(2) Adjusted EBITDA margin is defined as adjusted EBITDA as a percentage of net revenue. (3) Adjusted net operating income (Adjusted NOI) is defined as net income or net loss (computed in accordance with GAAP), excluding: net interest expenses, income tax expenses (benefits), depreciation and amortization, accretion expenses for asset retirement costs, share-based compensation expenses, selling and marketing expenses, general and administrative expenses, research and development expenses, foreign currency exchange loss (gain), government grants and others. (4) Adjusted NOI margin is defined as adjusted NOI as a percentage of net revenue. Our management and board of directors use adjusted EBITDA, adjusted EBITDA margin, adjusted NOI, and adjusted NOI margin, which are non-GAAP financial measures, to evaluate our operating performance, establish budgets and develop operational goals for managing our business. In particular, we believe that the exclusion of the income and expenses eliminated in calculating adjusted EBITDA and adjusted NOI can provide a useful measure of our core operating performance. 4 We also present these non-GAAP measures because we believe these non-GAAP measures are frequently used by securities analysts, investors and other interested parties as measures of the financial performance of companies in our industry. These non-GAAP financial measures are not defined under U.S. GAAP and are not presented in accordance with U.S. GAAP. These non-GAAP financial measures have limitations as analytical tools, and when assessing our operating performance, cash flows or our liquidity, investors should not consider them in isolation, or as a substitute for net income (loss), cash flows provided by operating activities or other consolidated statements of operations and cash flow data prepared in accordance with U.S. GAAP. There are a number of limitations related to the use of these non-GAAP financial measures instead of their nearest GAAP equivalent. First, adjusted EBITDA, adjusted EBITDA margin, adjusted NOI, and adjusted NOI margin are not substitutes for gross profit, net income (loss), cash flows provided by operating activities or other consolidated statements of operation and cash flow data prepared in accordance with U.S. GAAP. Second, other companies may calculate these non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of these non-GAAP financial measures as tools for comparison. Finally, these non-GAAP financial measures do not reflect the impact of net interest expenses, incomes tax benefits, depreciation and amortization, accretion expenses for asset retirement costs, and share-based compensation expenses, each of which have been and may continue to be incurred in our business. We mitigate these limitations by reconciling the non-GAAP financial measure to the most comparable U.S. GAAP performance measure, all of which should be considered when evaluating our performance. The following table reconciles our adjusted EBITDA in the years presented to the most directly comparable financial measure calculated and presented in accordance with U.S. GAAP, which is net income or net loss: Year Ended December 31, 2015 RMB 2016 RMB (in thousands, except for numbers of shares and per share data) 2017 RMB 2018 RMB RMB 2019 US$ Net loss Net interest expenses Income tax (benefits) expenses Depreciation and amortization Accretion expenses for asset retirement costs Share-based compensation expenses Adjusted EBITDA (98,584) (276,412) (326,900) 406,403 263,164 125,546 (6,076) (8,315) (11,983) 378,130 227,355 145,406 949 588 255 64,165 4,061 59,843 270,545 164,701 (442,083) (63,502) 915,676 131,529 2,248 741,507 1,142,032 164,043 429 27,257 512,349 1,046,538 1,824,021 262,004 (430,268) 636,973 (9,391) 2,990 189,756 1,840 105,877 15,650 The following table reconciles our adjusted NOI in the years presented to the most directly comparable financial measure calculated and presented in accordance with U.S. GAAP, which is net income or net loss: Year Ended December 31, 2015 RMB 2016 RMB (in thousands, except for numbers of shares and per share data) 2017 RMB 2018 RMB RMB 2019 US$ Net loss Net interest expenses Income tax (benefits) expenses Depreciation and amortization Accretion expenses for asset retirement costs Share-based compensation expenses Selling and marketing expenses (1) General and administrative expenses (1) Research and development expenses (1) Foreign currency exchange (gain) loss, net Government grants Others, net Adjusted NOI 15,650 (430,268) 636,973 (9,391) (98,584) (276,412) (326,900) 406,403 263,164 125,546 (6,076) (8,315) (11,983) 378,130 227,355 145,406 949 588 255 59,843 64,165 4,061 71,728 64,988 57,263 165,785 152,054 111,403 6,062 8,324 3,304 12,299 (18,310) (11,107) (3,062) (2,217) (3,915) (284) (1,174) (435) 475,100 320,475 (442,083) (63,502) 915,676 131,529 2,248 741,507 1,142,032 164,043 429 27,257 12,994 34,535 2,584 862 (1,422) (799) 764,726 1,322,585 2,163,442 310,758 1,840 105,877 85,357 207,255 12,394 (20,306) (3,217) (5,436) 2,990 189,756 90,465 240,433 17,986 6,000 (9,898) (5,565) (1) Selling and marketing expenses, general and administrative expenses and research and development expenses exclude depreciation and amortization and share- based compensation expenses. 5 B. Capitalization and Indebtedness Not required. C. Reasons for the Offer and Use of Proceeds Not required. D. Risk Factors Risks Relating to Our Business and Industry A slowdown in the demand for data center capacity or managed services could have a material adverse effect on us. Adverse developments in the data center market, in the industries in which our customers operate, or in demand for cloud computing could lead to a decrease in the demand for data center capacity or managed services, which could have a material adverse effect on us. We face risks including: a decline in the technology industry, such as a decrease in the use of mobile or web-based commerce, business layoffs or downsizing, relocation of businesses, increased costs of complying with existing or new government regulations and other factors; a reduction in cloud adoption or a slowdown in the growth of the internet generally as a medium for commerce and communication and the use of cloud-based platforms and services in particular; a downturn in the market for data center capacity generally, which could be caused by an oversupply of or reduced demand for space, and a downturn in cloud-based data center demand in particular; and the rapid development of new technologies or the adoption of new industry standards that render our or our customers’ current products and services obsolete or unmarketable and, in the case of our customers, that contribute to a downturn in their businesses, increasing the likelihood of a default under their service agreements or that they become insolvent. To the extent that any of these or other adverse conditions occur, they are likely to impact market demand and pricing for our services. Any inability to manage the growth of our operations could disrupt our business and reduce our profitability. We have experienced significant growth in recent years. Our net revenue grew from RMB1,616.2 million in 2017 to RMB2,792.1 million in 2018, representing an increase of 72.8%, and further increased to RMB4,122.4 million (US$592.1 million) in 2019, representing an increase of 47.6%. We derive net revenue primarily from colocation services and, to a lesser extent, managed services. In addition, we also sell IT equipment either on a stand-alone basis or bundled in a managed service agreement and provide consulting services. Our net revenues from colocation services were RMB1,219.1 million, RMB2,104.3 million and RMB3,261.7 million (US$468.5 million) in 2017, 2018 and 2019, representing 75.4%, 75.4% and 79.1% of total net revenue over the same periods, respectively. Our net revenues from managed services and other services were RMB372.8 million, RMB655.2 million and RMB832.8 million (US$119.6 million) in 2017, 2018 and 2019, representing 23.1%, 23.4% and 20.2% of total net revenue over the same periods, respectively. Our net revenue from IT equipment sales were RMB24.3 million, RMB32.6 million and RMB27.9 million (US$4.0 million) in 2017, 2018 and 2019, representing 1.5%, 1.2% and 0.7% of total net revenue, respectively. Our operations have also expanded in recent years through increases in the number and size of the data center facilities we operate, which we expect will continue to grow. Our rapid growth has placed, and will continue to place, significant demands on our management and our administrative, operational and financial systems. Continued expansion increases the challenges we face in: obtaining suitable sites or land to build new data centers; 6 establishing new operations at additional data centers and maintaining efficient use of the data center facilities we operate; managing a large and growing customer base with increasingly diverse requirements; expanding our service portfolio to cover a wider range of services, including managed cloud services; creating and capitalizing on economies of scale; obtaining additional capital to meet our future capital needs; recruiting, training and retaining a sufficient number of skilled technical, sales and management personnel; maintaining effective oversight over personnel and multiple data center locations; coordinating work among sites and project teams; and developing and improving our internal systems, particularly for managing our continually expanding business operations. In addition, we have grown our business through acquisitions in the past and intend to continue selectively pursuing strategic partnerships and acquisitions to expand our business. From time to time, we may have a number of pending investments and acquisitions that are subject to closing conditions. See "Item 4. Information on the Company-A. History and Development of the Company." There can be no assurance that we will be able to identify, acquire and successfully integrate other businesses and, if necessary, to obtain satisfactory debt or equity financing to fund those acquisitions. See "-We have expanded in the past and expect to continue to expand in the future through acquisitions of other companies, each of which may divert our management's attention, result in additional dilution to stockholders or use resources that are necessary to operate our business." If we fail to manage the growth of our operations effectively, our businesses and prospects may be materially and adversely affected. If we are not successful in expanding our service offerings, we may not achieve our financial goals and our results of operations may be adversely affected. We have been expanding, and plan to continue to expand, the nature and scope of our service offerings, particularly into the area of managed cloud services, including direct private connection to major cloud platforms , an innovative service platform for managing hybrid clouds and, where required, the resale of public cloud services. The success of our expanded service offerings depends, in part, upon demand for such services by new and existing customers and our ability to meet their demand in a cost- effective manner. We may face a number of challenges expanding our service offerings, including: acquiring or developing the necessary expertise in IT; maintaining high-quality control and process execution standards; maintaining productivity levels and implementing necessary process improvements; controlling costs; and successfully attracting existing and new customers for new services we develop. 7 A failure by us to effectively manage the growth of our service portfolio could damage our reputation, cause us to lose business and adversely affect our results of operations. In addition, because managed cloud services may require significant upfront investment, we expect that continued expansion into these services will reduce our profit margins. In the event that we are unable to successfully grow our service portfolio, we could lose our competitive edge in providing our existing colocation and managed services, since significant time and resources that are devoted to such growth could have been utilized instead to improve and expand our existing colocation and managed services. We face risks associated with having a long selling and implementation cycle for our services that requires us to make significant capital expenditures and resource commitments prior to recognizing revenue for those services. We have a long selling cycle for our services, which typically requires significant investment of capital, human resources and time by both our customers and us. Constructing, developing and operating our data centers require significant capital expenditures. A customer’s decision to utilize our colocation services, our managed solutions or our other services typically involves time-consuming contract negotiations regarding the service level commitments and other terms, and substantial due diligence on the part of the customer regarding the adequacy of our infrastructure and attractiveness of our resources and services. Furthermore, we may expend significant time and resources in pursuing a particular sale or customer, and we do not recognize revenue for our services until such time as the services are provided under the terms of the applicable agreement. Our efforts in pursuing a particular sale or customer may not be successful, and we may not always have sufficient capital on hand to satisfy our working capital needs between the date on which we sign an agreement with a new customer and when we first receive revenue for services delivered to the customer. If our efforts in pursuing sales and customers are unsuccessful, or our cash on hand is insufficient to cover our working capital needs over the course of our long selling cycle, our financial condition could be negatively affected. The data center business is capital-intensive, and we expect our capacity to generate capital in the short term will be insufficient to meet our anticipated capital requirements. The costs of constructing, developing and operating data centers are substantial. Further, we may encounter development delays, excess development costs, or delays in developing space for our customers to utilize. We also may not be able to secure suitable land or buildings for new data centers or at a cost on terms acceptable to us. We are required to fund the costs of constructing, developing and operating our data centers with cash retained from operations, as well as from financings from bank and other borrowings. Moreover, the costs of constructing, developing and operating data centers have increased in recent years, and may further increase in the future, which may make it more difficult for us to expand our business and to operate our data centers profitably. Based on our current expansion plans, we do not expect that our net revenue in the short term will be sufficient to offset increases in these costs, or that our business operations in the short term will generate capital sufficient to meet our anticipated capital requirements. If we cannot generate sufficient capital to meet our anticipated capital requirements, our financial condition, business expansion and future prospects could be materially and adversely affected. Our substantial level of indebtedness could adversely affect our ability to raise additional capital to fund our operations, expose us to interest rate risk to the extent of our variable rate debt and prevent us from meeting our obligations under our indebtedness. We have substantial indebtedness. As of December 31, 2019, we had total consolidated indebtedness of RMB16,189.5 million (US$2,325.5 million), including borrowings, finance lease and other financing obligations and convertible bonds. Based on our current expansion plans, we expect to continue to finance our operations through the incurrence of debt. Our indebtedness could, among other consequences: make it more difficult for us to satisfy our obligations under our indebtedness, exposing us to the risk of default, which, in turn, would negatively affect our ability to operate as a going concern; require us to dedicate a substantial portion of our cash flows from operations to interest and principal payments on our indebtedness, reducing the availability of our cash flows for other purposes, such as capital expenditures, acquisitions and working capital; limit our flexibility in planning for, or reacting to, changes in our business and the industries in which we operate; increase our vulnerability to general adverse economic and industry conditions; 8 place us at a disadvantage compared to our competitors that have less debt; expose us to fluctuations in the interest rate environment because the interest rates on borrowings under our project financing agreements are variable; increase our cost of borrowing; limit our ability to borrow additional funds; and require us to sell assets to raise funds, if needed, for working capital, capital expenditures, acquisitions or other purposes. As a result of covenants and restrictions, we are limited in how we conduct our business, and we may be unable to raise additional debt or equity financing to compete effectively or to take advantage of new business opportunities. Our current or future borrowings could increase the level of financial risk to us and, to the extent that the interest rates are not fixed and rise, or that borrowings are refinanced at higher rates, our available cash flow and results of operations could be adversely affected. We have financing arrangements in place with various lenders to support specific data center construction projects. Certain of these financing arrangements are secured by share pledge over equity interests of our subsidiaries, our accounts receivable, property and equipment and land use rights. The terms of these financing arrangements may impose covenants and obligations on the part of our borrowing subsidiary and/or our consolidated VIEs, namely GDS Beijing and its subsidiaries, and our company as guarantor. For example, some of these agreements contain requirements to maintain a specified minimum cash balance at all times or require that the borrowing subsidiary maintain a certain debt-to-equity ratio. We cannot provide any assurances that we will always be able to meet any covenant tests under our financing arrangements. Other loan facility agreements of ours require that STT GDC, one of our major shareholders, maintain an ownership percentage in our company of at least 25%. If STT GDC’s ownership in our company were to decrease below this percentage, pursuant to the terms of relevant facility agreements we could be obligated to notify the lender or repay any loans outstanding immediately or on an accelerated repayment schedule. In addition, other loan facility agreements of ours require that the IDC license of GDS Beijing or the borrowing subsidiaries, or the authorization by GDS Beijing to one such subsidiary to operate the data center business and provide IDC services under the auspices of the IDC license held by GDS Beijing, be maintained and renewed on or before the expiry date of the IDC license or authorization thereunder, as applicable. However, we have learned that the Ministry of Commerce, or the MOFCOM and the MIIT will not allow subsidiaries authorized to provide IDC services by an IDC license holder to renew its current authorization in the future; instead, the MIIT will require subsidiaries of IDC license holders to apply for their own IDC licenses. See “—Risks Related to Doing Business in the People’s Republic of China—We may be regarded as being non-compliant with the regulations on VATS due to the lack of IDC licenses for which penalties may be assessed that may materially and adversely affect our business, financial condition, growth strategies and prospects.” If the subsidiaries of GDS Beijing cannot renew their authorizations to provide IDC services timely under the auspices of GDS Beijing’s IDC license timely, and such subsidiaries cannot apply for and obtain their own IDC licenses, we also could be obligated to notify the lender or repay any loans outstanding immediately or on an accelerated repayment schedule. In May 2019, one of GDS Beijing's subsidiaries, GDS Suzhou, obtained its own IDC license. In September and November 2019, the other two of GDS Beijing's subsidiaries, Beijing Wan Chang Yun Science & Technology Co., Ltd., or Beijing Wan Chang Yun, and Shenzhen Yaode Data Services Co., Ltd., or Shenzhen Yaode obtained their own IDC license respectively. Other subsidiaries of our VIEs plan to apply for their own IDC licenses in order to continue to maintain authorizations to provide IDC services. The terms of any future indebtedness we may incur could include more restrictive covenants. A breach of any of these covenants could result in a default with respect to the related indebtedness. If a default occurs, the relevant lenders could elect to declare the indebtedness, together with accrued interest and other fees, to be due and payable immediately. This, in turn, could cause our other debt, to become due and payable as a result of cross-default or acceleration provisions contained in the agreements governing such other debt. In the event that some or all of our debt is accelerated and becomes immediately due and payable, we may not have the funds to repay, or the ability to refinance, such debt. In mid-August 2019, the PBOC decided to reform the formation mechanism of the Loan Prime Rate ("LPR") and authorized the National Interbank Funding Center to release LPR monthly, which may have indirect impact on the interest rate. The LPR reform could contribute to the decline of the loan rate for enterprises and the reduction of the financing cost for the real economy. High quality enterprises may get cheaper loans from the bank due to this more market-oriented interest rate mechanism. However, there is still uncertainty over the long-term effect of the LPR reform and its impact on our indebtedness. 9 We will likely require additional capital to meet our future capital needs, which may adversely affect our financial position and result in additional shareholder dilution. To grow our operations, we will be required to commit a substantial amount of operating and financial resources. Our planned capital expenditures, together with our ongoing operating expenses, will cause substantial cash outflows. In the near term, we will likely be unable to fund our expansion plans solely through our operating cash flows. Accordingly, we will likely need to raise additional funds through equity, equity-linked or debt financings in the future in order to meet our operating and capital needs. In this regard, at our annual general meeting, or AGM, held on August 6, 2019, our shareholders passed ordinary resolutions authorizing our board of directors to approve the allotment or issuance, in the 12-month period from the date of the AGM, of ordinary shares or other equity or equity-linked securities of our company up to an aggregate twenty percent (20%) of our existing issued share capital at the date of the AGM, whether in a single transaction or a series of transactions (other than any allotment or issues of shares on the exercise of any options that have been granted by our company). Additional debt or equity financing may not be available when needed or, if available, may not be available on satisfactory terms. Our inability to obtain additional debt and/or equity financing or to generate sufficient cash from operations may require us to prioritize projects or curtail capital expenditures and could adversely affect our results of operations. If we raise additional funds through further issuances of equity or equity-linked securities, our existing shareholders could suffer significant dilution in their percentage ownership of our company, and any new equity securities we issue could have rights, preferences and privileges senior to those of holders of our ordinary shares. In addition, any debt financing that we may obtain in the future could have restrictive covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. The ongoing COVID-19 pandemic could materially and adversely affect our business, results of operations and financial condition. Beginning in early 2020, there was an outbreak of a novel strain of coronavirus, later named COVID-19, in China. In March, the World Health Organization declared COVID-19 to be a pandemic. As part of its intensified efforts to contain the spread of COVID-19, the PRC government took a number of actions, including extending the Chinese New Year holiday, quarantining and otherwise treating individuals in China who are infected with COVID-19, asking residents to remain at home and to avoid public gatherings, among other actions. COVID-19 has resulted in temporary closures of many corporate offices, retail stores, and manufacturing facilities and factories across China. Substantially all of our revenues are generated in and our workforce are located in China. Consequently, our business could be adversely impacted by the effects of COVID-19 or other pandemics or epidemics. The construction of new data centers or the expansion of existing data centers might be significantly delayed because of temporary closures of our construction sites and shortages of workers due to travel restrictions that have been or may be imposed in China. The completion of pending acquisitions of data centers might also be delayed or suffer other adverse impacts due to the impact of COVID-19. If the construction of new data centers, the expansion of existing data centers, or the completion of our pending acquisitions of data centers cannot be completed or delivered on time, we may be unable to meet our customer demand as expected, which may adversely and materially affect our business, results of operations and financial conditions. Business distributions caused by the COVID-19 pandemic may also adversely and materially affect the business operations and financial condition of many of our customers, especially those that are small and medium-sized enterprises. Any prolonged disruption of our businesses or those of our customers or business partners could negatively impact our results of operations and financial condition. Our customers may start to encounter cash flow or operating difficulties, which may reduce their demand for our services, delay their payments to us thereby increasing our accounts receivable turnover days, or even increase the risk that they may default on their payment obligations. Any of these events would negatively affect our operating results. In response to the pandemic, we suspended our offline customer acquisition activities and business travel to ensure the safety and health of our employees. These measures may reduce our business operation capacity and are likely to negatively affect our operating results. 10 In addition, our results of operations could be adversely affected to the extent that this pandemic harms the Chinese economy or global economy in general. The costs of constructing, developing and operating data centers are substantial. See “—The data center business is capital-intensive, and we expect our capacity to generate capital in the short term will be insufficient to meet our anticipated capital requirements.” Expanding our data center capacity and growing our business requires substantial amounts of capital. If our existing cash resources are insufficient to meet our needs to expand our data center capacity and grow our business, we may seek to raise capital by selling equity or equity-linked securities, debt securities or by arranging financing and incurring indebtedness through borrowing from banks. Any economic slowdown in China or worldwide due to COVID-19 may result in a shortage of available credit and insufficient funds for our future expansion or growth, and we may not be able to raise additional capital, obtain additional financing from banks or other financial institutions, or draw down our existing loans and financing facilities. We cannot assure you that financing will be available in the amounts we need or on terms acceptable to us, if at all. If we were unable to obtain additional equity or debt financing as required, our business, operations and prospects and our ability to maintain our desired level of revenue growth may suffer materially. This in turn could limit our capital expenditures and cause our revenues to decrease, and our business, results of operations and financial condition may be materially and adversely affected as a result. The extent to which COVID-19 impacts our business, results of operations and financial condition will depend on ongoing and future developments, including new information concerning its global severity, new regulations and policies adopted and actions taken in response, all of which are highly uncertain and unpredictable. Increased power costs and limited availability of power resources, together with stringent regulatory requirements or restrictions on data center development, may adversely affect our results of operations. We are a large consumer of power and costs of power account for a significant portion of our cost of revenue. We require power supply to provide many services we offer, such as powering and cooling our customers’ servers and network equipment and operating critical data center plant and equipment infrastructure. Since we rely on two suppliers, State Grid and Southern Grid, each of which has a monopoly in its area of operation, to provide our data centers with power, our data centers could have limited or inadequate access to power. More stringent requirements or restrictions imposed by local authorities in the Tier 1 markets, including Beijing, Shanghai, Shenzhen and Guangzhou, as to energy conservation or industrial policies may also limit our ability to obtain the regulatory approvals for the development and operation of data centers, which are essential for us to obtain power supply and expand our business. For example, the Development and Reform Commission of Shenzhen Municipality, or Shenzhen DRC, issued regulations in the first half of 2017 to tighten the requirements for energy conservation review of fixed-asset investment projects for data centers by requiring all such projects to obtain an energy conservation review opinion from Shenzhen DRC regardless of the amount of their energy consumption and conditioning its approval of power supply applications on the receipt of such energy conservation review opinion. In September 2018, the General Office of the People's Government of Beijing Municipality issued the Beijing Municipality's Catalogue for the Prohibition and Restriction of Newly Increased Industries (2018 Edition) to strictly control new construction or expansion of data centers in Beijing. In January 2019, the Shanghai Municipal Commission of Economy and Informatization and the Shanghai Municipal Development and Reform Commission jointly published their Guideline Opinion on Coordinated Construction of Internet Data Centers in Shanghai to control the aggregate number of newly increased IDC racks within the period from 2019 to 2020 in Shanghai. In April 2019, the Shenzhen DRC published a Notice on the Relevant Matters of Energy Conservation Examination for Data Centers to strictly control the newly increased amount of annual comprehensive energy consumption of data centers. While we endeavor to obtain the regulatory approvals for the development and operation of our data centers (including conducting relevant energy conservation examinations of our data center construction projects to meet the requirements under relevant laws and regulations (including requirements of local authorities), we may incur additional costs in order to fulfill such requirements, and we cannot assure you that all our data centers have met all the requirements or that we have obtained or will obtain all relevant approvals, the lack of which could have a material and adverse effect on our business and expected growth. 11 The amount of power required by our customers may increase as they adopt new technologies, for example, for virtualization of hardware resources and for specialized processing of artificial intelligence. As a result, the average amount of power utilized per server is increasing, which in turn increases power consumption required to cool the data center facilities. Pursuant to our colocation service agreements, we provide our customers with a committed level of power supply availability. Although we aim to improve the energy efficiency of the data center facilities that we operate, there can be no assurance such data center facilities will be able to provide sufficient power to meet the growing needs of our customers. Our customers’ demand for power may exceed the power capacity in our older data centers, which may limit our ability to fully utilize the net floor area of these data centers. We may lose customers or our customers may reduce the services purchased from us due to increased power costs, and limited availability of power resources, or we may incur costs for data center capacity which we cannot utilize, which would reduce our net revenue and have a material and adverse effect on our cost of revenue and results of operations. We attempt to manage our power resources and limit exposure to system downtime due to power outages from the electric grid by having redundant power feeds from the grid and by using backup generators and battery power. However, these protections may not limit our exposure to power shortages or outages entirely. Any system downtime resulting from insufficient power resources or power outages could damage our reputation and lead us to lose current and potential customers, which would harm our financial condition and results of operations. We have a history of net losses and may continue to incur losses in the future. We incurred net losses of RMB326.9 million RMB430.3 million and RMB442.1 million (US$63.5 million) in 2017, 2018 and 2019, respectively, and we may incur losses in the future. We expect our costs and expenses to increase as we expand our operations, primarily including costs and expenses associated with owning and leasing data center capacity, increasing our headcount and utility expenses. Our ability to achieve and maintain profitability depends on the continued growth and maintenance of our customer base, our ability to control our costs and expenses, the expansion of our service offerings and our ability to provide our services at the level needed to satisfy the stringent demands of our customers. In addition, our ability to achieve profitability is affected by many factors which are beyond our control, such as the overall demand for data center services in China and general economic conditions. If we cannot efficiently manage the data center facilities we operate, our financial condition and results of operations could be materially and adversely affected. We may continue to incur losses in the future due to our continued investments in leasing data center capacity, increased headcount and increased utility expenses. Any significant or prolonged failure in the data center facilities we operate or services we provide would lead to significant costs and disruptions and would reduce our net revenue, harm our business reputation and have a material adverse effect on our results of operation. The data center facilities we operate are subject to failure. Any significant or prolonged failure in any data center facility we operate or services that we provide, including a breakdown in critical plant, equipment or services, such as the cooling equipment, generators, backup batteries, routers, switches, or other equipment, power supplies, or network connectivity, whether or not within our control, could result in service interruptions and data losses for our customers as well as equipment damage, which could significantly disrupt the normal business operations of our customers and harm our reputation and reduce our net revenue. Any failure or downtime in one of the data center facilities that we operate could affect many of our customers. The total destruction or severe impairment of any of the data center facilities we operate could result in significant downtime of our services and catastrophic loss of customer data. Since our ability to attract and retain customers depends on our ability to provide highly reliable service, even minor interruptions in our service could harm our reputation and cause us to incur financial penalties. The services we provide are subject to failures resulting from numerous factors, including: power loss; equipment failure; human error or accidents; theft, sabotage and vandalism; failure by us or our suppliers to provide adequate service or maintenance to our equipment; network connectivity downtime and fiber cuts; 12 security breaches to our infrastructure; improper building maintenance by us or by the landlords of the data center buildings which we lease; physical, electronic and cyber security breaches; fire, earthquake, hurricane, tornado, flood and other natural disasters; extreme temperatures; water damage; public health emergencies; and terrorism. We have in the past experienced, and may in the future experience, interruptions in service due to power outages or other technical failures or for reasons outside of our control, including a service interruption that caused system downtime to certain banking and financial institution customers and other customers. These interruptions in service, regardless of whether they result in breaches of the service level agreements we have with customers, may negatively affect our relationships with customers, including resulting in customers terminating their agreements with us or seeking damages from us or other compensatory actions. Interruptions in service may also have consequences for customers, such as banking and financial institutions, that are under the oversight of industry regulators, including the China Banking and Insurance Regulatory Commission, or CBIRC, and other PRC regulatory agencies. In response to such interruptions in service, industry regulators have taken, and may in the future take, various regulatory actions, including notifications or citations to our customers, over which they have oversight. Such regulatory actions with respect to our customers, including banking and financial institutions, could negatively impact our relationships with such customers, lead to audits of our services, inspections of our facilities, place restrictions or prohibitions upon the ability of such institutions to use our services, and thereby negatively affect our business operations and results of operations. We have taken and continue to take steps to improve our infrastructure to prevent service interruptions, including upgrading our electrical and mechanical infrastructure and sourcing, designing the best facilities possible and implementing rigorous operational procedures to maintenance programs to manage risk. However, we cannot assure you that such interruptions in service will not occur again in the future, or that such incidents will not result in the loss of customers and revenue, our paying compensation to customers, reputational damage to us, penalties or fines against us, and would not have a material and adverse effect on our business and results of operations. See “Item 4. Information on the Company—B. Business Overview—Regulatory Matters—Regulations Related to Information Technology Outsourcing Services Provided to Banking Financial Institutions.” Service interruptions continue to be a significant risk for us and could affect our reputation, damage our relationships with customers and materially and adversely affect our business. Delays in the construction of new data centers or the expansion of existing data centers could involve significant risks to our business. In order to meet customer demand and the continued growth of our business, we need to expand existing data centers, lease buildings for conversion into new data center facilities or obtain suitable land to build new data centers. Expansion of existing data centers and/or construction of new data centers are currently underway or being contemplated and such expansion and/or construction require us to carefully select and rely on the experience of one or more designers, general contractors, and subcontractors during the design and construction process. If a designer or contractor experiences financial or other problems during the design or construction process, we could experience significant delays and/or incur increased costs to complete the projects, resulting in negative impacts on our results of operations. In addition, we need to work closely with the local power suppliers, and sometimes local governments, where our proposed data centers are located. Delays in actions that require the assistance of such third parties, or delays in receiving required permits and approvals from such parties, may also affect the speed with which we complete data center projects or result in their not being completed at all. We have experienced such delays in receiving approvals and permits or in actions to be taken by third parties in the past and may experience them again in the future. 13 If we experience significant delays in the supply of power required to support the data center expansion or new construction, either during the design or construction phases, the progress of the data center expansion and/or construction could deviate from our original plans, which could , among others, result in liability for penalties and loss of customers, and cause material and negative effect to our revenue growth, profitability and results of operations. The occurrence of a catastrophic event or a prolonged disruption may exceed our insurance coverage by significant amounts. Our operations are subject to hazards and risks normally associated with the daily operations of our data center facilities. Currently, we maintain insurance policies in eight categories: construction and installation, work interruption expense due to public health event, business interruption for lost profits, property and casualty, public liability, directors and officers liability, employer liability and commercial employee insurance. Our business interruption insurance for lost profits includes coverage for business interruptions, our property and casualty insurance includes coverage for equipment breakdowns and our commercial employee insurance includes employee group insurance and senior management medical insurance. We believe our insurance coverage adequately covers the risks of our daily business operations. However, our current insurance policies may be insufficient in the event of a prolonged or catastrophic event. The occurrence of any such event that is not entirely covered by our insurance policies may result in interruption of our operations and subject us to significant losses or liabilities and damage our reputation as a provider of business continuity services. In addition, any losses or liabilities that are not covered by our current insurance policies may have a material adverse effect on our business, financial condition and results of operations. We may be vulnerable to security breaches which could disrupt our operations and have a material adverse effect on our financial condition and results of operations. A party who is able to compromise the security measures protecting the data center facilities we operate or any of the data stored in such data center facilities could misappropriate our or our customers’ proprietary information or cause interruptions or malfunctions in our operations. As we provide assurances to our customers that we provide the highest level of security, such a compromise could be particularly harmful to our brand and reputation. We may be required to expend significant capital and resources to protect against such threats or to alleviate problems caused by breaches in security. In addition, as we continue expanding our service offerings in managed cloud services, including direct private connection to major cloud platforms and the provision of cloud infrastructure, we will face greater risks from potential attacks because the provision of cloud-related services will increase the flow of internet user data through the data center facilities we operate and create broader public access to our system. As techniques used to breach security change frequently and are often not recognized until launched against a target, we may not be able to implement new security measures in a timely manner or, if and when implemented, we may not be certain whether these measures could be circumvented. Any breaches that may occur could expose us to increased risk of lawsuits, regulatory penalties, loss of existing or potential customers, harm to our reputation and increases in our security costs, which could have a material adverse effect on our financial condition and results of operations. Security risks and deficiencies may also be identified in the course of government inspections, which could subject us to fines and other sanctions. During construction of certain of our facilities, government inspectors have cited security risks at our construction sites and subjected us and our legal representative to fines for such risks. We cannot assure you that similar fines and sanctions will not occur in the future, or that such fines and sanctions will not result in damage to our business and reputation, which could have a material and adverse effect on our results of operations. In addition, any assertions of alleged security breaches or systems failure made against us, whether true or not, could harm our reputation, cause us to incur substantial legal fees and have a material adverse effect on our business, reputation, financial condition and results of operations. 14 Our ability to provide data center services depends on the major telecommunications carriers in China providing sufficient network services to our customers in the data center facilities that we operate on commercially acceptable terms. Our ability to provide data center services depends on the major telecommunications carriers in China, namely China Telecom, China Unicom and China Mobile, providing sufficient network connectivity and capacity to enable our customers to transfer data to and from equipment that they locate in the data center facilities that we operate. Furthermore, given the limited competition among basic service providers in the telecommunications market in China, we depend on the dominant carrier in each location to provide such services to our customers on commercially acceptable terms. Although we believe we have maintained good relationships with China Telecom, China Unicom and China Mobile in the past, there can be no assurance that they will continue to provide the network services that our customers require on commercially acceptable terms at each of the data centers where we operate, if at all. In addition, if China Telecom, China Unicom or China Mobile increases the price of their network services, it would have a negative impact on the overall cost-effectiveness of data center services in China, which could cause our customers’ demand for our services to decline and would materially and adversely affect our business and results of operations. Our leases for self-developed data centers or our agreements for third-party data centers could be terminated early and we may not be able to renew our existing leases and agreements on commercially acceptable terms or our rent or payment under the agreements could increase substantially in the future, which could materially and adversely affect our operations. Most of our self-developed data centers are located in properties that we hold under long-term leases. Such leases generally have fifteen to twenty-year terms from inception. In some instances, we may negotiate an option to purchase the leased premises and facilities or a right of first refusal for the renewal of the existing leases according to the terms and conditions under the relevant lease agreements. However, upon the expiration of such leases, we may not be able to renew these leases on commercially reasonable terms, if at all. Under certain lease agreements, the lessor may terminate the agreement by giving prior notice and paying default penalties to us. However, such default penalties may not be sufficient to cover our losses. Even though the lessors for most of our data centers generally do not have the right of unilateral early termination unless they provide the required notice, the lease may nonetheless be terminated early if we are in material breach of the lease agreements. We may assert claims for compensation against the landlords if they elect to terminate a lease agreement early and without due cause. If the leases for our data centers were terminated early prior to their expiration date, notwithstanding any compensation we may receive for early termination of such leases, or if we are not able to renew such leases, we may have to incur significant cost related to relocation. In addition, we have entered into six agreements in respect of data centers in operation with parties who have not produced evidence of proper legal title of the premises, and although we may seek damages from such parties, such leases may be void and we may be forced to relocate. Four of our data centers are located in properties that were already mortgaged to third parties before the commencement of the lease. If such third parties claim their rights on the mortgaged properties in case of default or breach under the principal debt by the lessors or other relevant parties, we may not be able to protect our leasehold interest and may be ordered to vacate the affected premises. Any relocation could also affect our ability to provide continuous uninterrupted services to our customers and harm our reputation. As a result, our business and results of operations could be materially and adversely affected. Furthermore, certain portions of our data center operations are located in third-party data centers that we lease from wholesale data center providers. Our agreements with third parties are typically five years but may also be up to ten years. Under some of such agreements, we have the right of first refusal to renew the agreements subject to mutual agreement with the third parties. Some of such agreements allow the third parties to terminate the agreements early, subject to a notification period requirement and the payment of a pre-determined termination fee, which in some cases may not be sufficient to cover any direct and indirect losses we might incur as a result. Although historically we have successfully renewed all agreements we wanted to renew, and we do not believe that any of our agreements will be terminated early in the future, there can be no assurance that the counterparties will not terminate any of our agreements prior to its expiration date. We plan to renew our existing agreements with third parties upon expiration or migrate our operations to the data centers leased or owned by our company. However, we may not be able to renew these agreements on commercially acceptable terms, if at all, or the space in data centers that we lease or own may not be adequate for us to relocate such operations, and we may experience an increase in our payments under such agreements. Any adverse change to our ability to exert operational control over any of the data center facilities we operate could have a material adverse effect on our ability to operate these data center facilities at the standards required for us to meet our service level commitments to our customers. 15 We generate significant revenue from data centers located in only a few locations and a significant disruption to any location could materially and adversely affect our operations. We generate significant revenue from data centers located in only a few locations and a significant disruption to any single location could materially and adversely affect our operations. As of the date of this annual report, most of our data centers (self- developed and third-party) are located in our Tier 1 markets. Furthermore, several of our data centers are located on campuses or clusters in close proximity to each other in specific districts within our Tier 1 markets. The occurrence of a catastrophic event, or a prolonged disruption in any of these regions, could materially and adversely affect our operations. Our net revenue is highly dependent on a limited number of customers, and the loss of, or any significant decrease in business from, any one or more of our major customers could adversely affect our financial condition and results of operations. We consider our customers to be the end users of our data center services. We may enter into agreements directly with our end user customers or through intermediate contracting parties. See “Item 4. Information on the Company—B. Business Overview— Our Customers.” We have in the past derived, and believe that we will continue to derive, a significant portion of our net revenue from a limited number of customers. We had one end user customer that generated 25.2% of our total net revenue in 2017 and two end user customers that generated 27.0% and 17.4% of our total net revenue, respectively, in 2018. We had three end user customers that generated 27.2%, 19.1% and 10.8% of our total net revenue, respectively, in 2019. No other end user customer accounted for 10% or more of our total net revenue during those periods. We expect our net revenue will continue to be highly dependent on a limited number of end user customers who account for a large percentage of our total area committed. As of December 31, 2019, we had three end user customers who accounted for 30.6%, 21.1%, and 10.4%, respectively, of our total area committed (excluding joint venture data centers). No other end user customer accounted for 10% or more of our total area committed (excluding joint venture data centers). Moreover, for several of our data centers, a limited number of end user customers accounted for or are expected to account for a substantial majority of area committed or area utilized, including some cases where a single end user customer accounted for all area committed or area utilized. If there are delays in the move in, whereby the net floor area they are committed to is not utilized as expected, or there is contract termination in relation to these customers, then our net revenue and results of operations would be materially and adversely affected. There are a number of factors that could cause us to lose major customers. Because many of our agreements involve services that are mission-critical to our customers, any failure by us to meet a customer’s expectations could result in cancellation or non- renewal of the agreement. Our service agreements usually allow our customers to terminate their agreements with us before the end of the contract period under certain specified circumstances, including our failure to deliver services as required under such agreements, and in some cases without cause as long as sufficient notice is given. In addition, our customers may decide to reduce spending on our services due to a challenging economic environment or other factors, both internal and external, relating to their business such as corporate restructuring or changing their outsourcing strategy by moving more facilities in-house or outsourcing to other service providers. Furthermore, our customers, some of whom have experienced rapid changes in their business, substantial price competition and pressures on their profitability, may demand price reductions or reduce the scope of services to be provided by us, any of which could reduce our profitability. In addition, our reliance on any individual customer for a significant portion of our net revenue may give that customer a degree of pricing leverage against us when negotiating agreements and terms of services with us. The loss of any of our major customers, or a significant decrease in the extent of the services that they outsource to us or the price at which we sell our services to them, could materially and adversely affect our financial condition and results of operations. If we are unable to meet our service level commitments, our reputation and results of operation could suffer. Most of our customer agreements provide that we maintain certain service level commitments to our customers. If we fail to meet our service level commitments, we may be contractually obligated to pay the affected customer a financial penalty, which varies by agreement, and the customer may in some cases be able to terminate its agreement. Although we have not had to pay any material financial penalties for failing to meet our service level commitments in the past, there is no assurance that we will be able to meet all of our service level commitments in the future and that no material financial penalties may be imposed. In addition, if such a failure were to occur, there can be no assurance that our customers will not seek other legal remedies that may be available to them, including: requiring us to provide free services; 16 seeking damages for losses incurred; and cancelling or electing not to renew their agreements. Any of these events could materially increase our expenses or reduce our net revenue, which would have a material adverse effect on our reputation and results of operations. Our failure to meet our commitments could also result in substantial customer dissatisfaction or loss. As a result of such customer loss and other potential liabilities, our net revenue and results of operations could be materially and adversely affected. Our customer base may decline if our customers or potential customers develop their own data centers or expand their own existing data centers. Some of our customers may develop their own data center facilities. Other customers with their own existing data centers may choose to expand their data center operations in the future. In the event that any of our key customers were to develop or expand their data centers, we may lose business or face pressure as to the pricing of our services. Although we believe that the trend is for companies in China to outsource more of their data center facilities and operations to colocation data center service providers, there can be no assurance that this trend will continue. In addition, if we fail to offer services that are cost-competitive and operationally advantageous as compared with services provided in-house by our customers, we may lose customers or fail to attract new customers. If we lose a customer, there is no assurance that we would be able to replace that customer at the same or a higher rate, or at all, and our business and results of operations would suffer. We may be unable to achieve high agreement renewal rates. We seek to renew customer agreements when those agreements are due for renewal. We endeavor to provide high levels of customer service, support, and satisfaction to maintain long-term customer relationships and to secure high rates of agreement renewals for our services. Nevertheless, we cannot assure you that we will be able to renew service agreements with our existing customers or re-commit space relating to expired service agreements to new customers if our current customers do not renew their agreements. In the event of a customer’s termination or non-renewal of expired agreements, or a renewal of an expired agreement for fewer services or less area than it had previously utilized, our ability to enter into services agreements so that new or other existing customers utilize the expired existing space in a timely manner will impact our results of operations. If such expired existing space is not utilized by new or other existing customers in a timely manner, our service revenue and results of operations may be negatively impacted. Our quarterly churn rate, which we define as the ratio of quarterly service revenue from agreements which terminated or expired without renewal during the quarter to the total quarterly service revenue for the preceding quarter, averaged 2.1%, 0.9% and 0.5% in 2017, 2018 and 2019, respectively. During 2020, data center service agreements with our customers with respect to 8.9% of our total area committed (excluding joint venture data centers) as of December 31, 2019 will become due for renewal. If we do not succeed in attracting new customers for our services and/or growing revenue from existing customers, we may not achieve our revenue growth goals. We have been expanding our customer base to cover a range of industry verticals, particularly cloud service providers and other internet-based businesses. Our ability to attract new customers, as well as our ability to grow revenue from our existing customers, depends on a number of factors, including our ability to offer high-quality services at competitive prices, the strength of our competitors and the capabilities of our marketing and sales teams to attract new customers. If we fail to attract new customers, we may not be able to grow our net revenue as quickly as we anticipate or at all. As our customer base grows and diversifies into other industries, we may be unable to provide customers with services that meet the specific demand of such customers or their industries, or with quality customer support, which could result in customer dissatisfaction, decreased overall demand for our services and loss of expected revenue. In addition, our inability to meet customer service expectations may damage our reputation and could consequently limit our ability to retain existing customers and attract new customers, which would adversely affect our ability to generate revenue and negatively impact our results of operations. 17 Customers who rely on us for the colocation of their servers, the infrastructure of their cloud systems, and management of their IT and cloud operations could potentially sue us for their lost profits or damages if there are disruptions in our services, which could impair our financial condition. As our services are critical to many of our customers’ business operations, any significant disruption in our services could result in lost profits or other indirect or consequential damages to our customers. Although our customer agreements typically contain provisions attempting to limit our liability for breach of the agreement, including failing to meet our service level commitments, there can be no assurance that a court would enforce any contractual limitations on our liability in the event that one of our customers brings a lawsuit against us as the result of a service interruption that they may ascribe to us. The outcome of any such lawsuit would depend on the specific facts of the case and any legal and policy considerations that we may not be able to mitigate. In such cases, we could be liable for substantial damage awards. Since we do not carry liability insurance coverage, such damage awards could seriously impair our financial condition. Our customers operate in a limited number of industries, particularly in the cloud services, internet and financial services industries. Factors that adversely affect these industries or information technology spending in these industries may adversely affect our business. Our customers operate in a limited number of industries, particularly in the cloud services, internet and financial services industries. As of December 31, 2019, end user customers from the cloud services, internet and financial services industries accounted for 72.6%, 14.3% and 6.9% of our total area committed, respectively. Our business and growth depend on continued demand for our services from our current and potential customers in the cloud services, internet and financial services industries. Demand for our services, and technology services in general, in any particular industry could be affected by multiple factors outside of our control, including a decrease in growth or growth prospects of the industry, a slowdown or reversal of the trend to outsource information technology operations, or consolidation in the industry. In addition, serving a major customer within a particular industry may effectively preclude us from seeking or obtaining engagements with direct competitors of that customer if there is a perceived conflict of interest. Any significant decrease in demand for our services by customers in these industries, or other industries from which we derive significant net revenue in the future, may reduce the demand for our services. We enter into fixed-price agreements with many customers, and our failure to accurately estimate the resources and time required for the fulfillment of our obligations under these agreements could negatively affect our results of operations. Our data center services are generally provided on a fixed-price basis that requires us to undertake significant projections and planning related to resource utilization and costs. Although our past project experience helps to reduce the risks associated with estimating, planning and performing fixed-price agreements, we bear the risk of failing to accurately estimate our projected costs, including power costs as we may not accurately predict our customer’s ultimate power usage once the agreement is implemented, and failing to efficiently utilize our resources to deliver our services, and there can be no assurance that we will be able to reduce the risk of estimating, planning and performing our agreements. Any failure to accurately estimate the resources and time required for a project, or any other factors that may impact our costs, could adversely affect our profitability and results of operations. Our customer agreement commitments are subject to reduction and potential cancellation. Many of our customer agreements allow for early termination, subject to payment of specified costs and penalties, which are usually less than the revenues we would expect to receive under such agreements. Our customer agreement commitments could significantly decrease if any of the customer agreements is terminated either pursuant to, or in violation of, the terms of such agreement. In addition, our customer agreement commitments during a particular future period may be reduced for reasons outside of our customers’ control, such as general prevailing economic conditions. It is difficult to predict how market forces, or PRC or U.S. government policy, in particular, the outbreak of a trade war between the PRC and the U.S. and the imposition of additional tariffs on bilateral imports in 2018 and 2019, may continue to impact the PRC economy as well as related demand for our colocation and managed services going forward. If our customer agreement commitments are significantly reduced, our results of operations and the price of our ADSs could be materially and adversely affected. 18 Even if our current and future customers have entered into a binding agreement with us, they may choose to terminate such agreement prior to the expiration of its terms. Any penalty for early termination may not adequately compensate us for the time and resources we have expended in connection with such agreement, or at all, which could have a material adverse effect on our results of operations and cash flows. We may not be able to compete effectively against our current and future competitors. We offer a broad range of data center services and, as a result, we may compete with a wide range of data center service providers for some or all of the services we offer. We face competition from the state-owned telecommunications carriers, namely China Telecom, China Unicom and China Mobile, as well as other domestic and international carrier-neutral data center service providers. Our current and future competitors may vary by size and service offerings and geographic presence. See “Item 4. Information on the Company—B. Business Overview— Competition.” Competition is primarily centered on reputation and track record, quality and availability of data center capacity, quality of service, technical expertise, security, reliability, functionality, breadth and depth of services offered, geographic coverage, financial strength and price. Some of our current and future competitors may have greater brand recognition, marketing, technical and financial resources than we do. As a result, some of our competitors may be able to: bundle colocation services with other services or equipment they provide at reduced prices; develop superior products or services, gain greater market acceptance, and expand their service offerings more efficiently or rapidly; adapt to new or emerging technologies and changes in customer requirements more quickly; take advantage of acquisition and other opportunities more readily; and adopt more aggressive pricing policies and devote greater resources to the promotion, marketing and sales of their services. We operate in a competitive market, and we face pricing pressure for our services. Prices for our services are affected by a variety of factors, including supply and demand conditions and pricing pressures from our competitors. Although we offer a broad range of data center services, our competitors that specialize in only one of our services offerings may have competitive advantages in that offering. With respect to all of our colocation services, our competitors may offer such services at rates below current market rates or below the rates we currently charge our customers. With respect to both our colocation and managed services offerings, our competitors may offer services in a greater variety that are more sophisticated or that are more competitively priced than the services we offer. We may be required to lower our prices to remain competitive, which may decrease our margins and adversely affect our business prospects, financial condition and results of operations. An oversupply of data center capacity could have a material adverse effect on us. A buildup of new data centers or reduced demand for data center services could result in an oversupply of data center capacity in China’s large commercial centers. Excess data center capacity could lower the value of data center services and limit the number of economically attractive markets that are available to us for expansion, which could negatively impact our business and results of operations. 19 Our failure to comply with regulations applicable to our leased data center buildings may materially and adversely affect our ability to use such data centers. Among the data center buildings that we lease, including those under construction, a majority of the lease agreements have not been registered or filed with relevant authorities in accordance with the applicable PRC laws and regulations. The enforcement of this legal requirement varies depending on local practices. In case of failure to register or file a lease, the parties to the unregistered lease may be ordered to make rectifications (which would involve registering such leases with the relevant authority) before being subject to penalties. The penalty ranges from RMB1,000 to RMB10,000 for each unregistered lease, at the discretion of the relevant authority. The law is not clear as to which of the parties, the lessor or the lessee, is liable for the failure to register the lease, and the lease agreements of several of our data centers provide that the lessor is responsible for processing the registration and must compensate us for losses caused by any breach of the obligation. Although we have proactively requested that the applicable lessors complete or cooperate with us to complete the registration in a timely manner, we are unable to control whether and when such lessors will do so. In the event that a fine is imposed on both the lessor and lessee, and if we are unable to recover from the lessor any fine paid by us in accordance with the terms of the lease agreement, such fine will be borne by us. In the case of one data center in Beijing, a portion of the building has been constructed without obtaining the building ownership certificate, and the part of the lease in relation to such portion may be deemed invalid if the construction has not been duly approved by the government, in which event we would not be able to use that portion of property. In respect of some data centers, the usage of leased buildings for data center purposes may be deemed to be inconsistent with the designated usage as stated under the building ownership certificates. If the owners fail to obtain the necessary consents and/or to comply with the applicable legal requirements for the change of usage of these premises, and the relevant authority or the court orders us to use the relevant leased buildings for the designated usage only, we may not be able to continue to use these buildings for data center purposes and we may need relocate our operation there to other suitable premises. We may also be subject to administrative penalties for lack of fire safety approvals for renovation of the leased premises, and we may be ordered to suspend operations at applicable premises if we fail to timely cure any such defect. Construction or renovation of certain other of our data centers was carried out without obtaining construction (including zoning) related permits, and certain leased premises were put into use without fulfillment of construction inspection and acceptance procedures, which may cause administrative penalties to be imposed on us in the case of renovation, and may cause the use of the leased premises to be deemed illegal, and we may be forced to suspend our operations as a result. See also “—Risks Related to Doing Business in the People’s Republic of China—Our business operations are extensively impacted by the policies and regulations of the PRC government. Any policy or regulatory change may cause us to incur significant compliance costs.” We cannot assure you that we will be able to relocate such operations to suitable alternative premises, and any such relocation may result in disruption to our business operations and thereby result in loss of earnings. We may also need to incur additional costs for the relocation of our operation. There is also no assurance that we will be able to effectively mitigate the possible adverse effects that may be caused by such disruption, loss or costs. Any of such disruption, loss or costs could materially and adversely affect our financial condition and results of operations. Our failure to maintain our relationships with various cloud service providers may adversely affect our managed cloud services, and as a result, our business, operating results and financial condition. Our managed cloud services involve providing services to the customers of cloud service providers. If we do not maintain good relationships with cloud service providers, our business could be negatively affected. If these cloud service providers fail to perform as required under our agreements for any reason or suffer service level interruptions or other performance issues, or if our customers are less satisfied than expected with the services provided or results obtained, we may not realize the anticipated benefits of these relationships. Since our agreements with key cloud service providers in China are non-exclusive, these companies may decide in the future to partner with more of our competitors or they may decide to terminate their agreements with us, any of which could adversely and materially affect our business expansion plan and expected growth. 20 Our data center infrastructure may become obsolete or unmarketable and we may not be able to upgrade our power, cooling, security or connectivity systems cost-effectively or at all. The markets for the data centers we own and operate, as well as certain of the industries in which our customers operate, are characterized by rapidly changing technology, evolving industry standards, frequent new service introductions, shifting distribution channels and changing customer demands. As a result, the infrastructure at our data centers may become obsolete or unmarketable due to demand for new processes and/or technologies, including, without limitation: (i) new processes to deliver power to, or eliminate heat from, computer systems; (ii) customer demand for additional redundancy capacity; (iii) new technology that permits higher levels of critical load and heat removal than our data centers are currently designed to provide; and (iv) an inability of the power supply to support new, updated or upgraded technology. In addition, the systems that connect our self-developed data centers, and in particular, our third-party data centers, to the internet and other external networks may become outdated, including with respect to latency, reliability and diversity of connectivity. When customers demand new processes or technologies, we may not be able to upgrade our data centers on a cost-effective basis, or at all, due to, among other things, increased expenses to us that cannot be passed on to customers or insufficient revenue to fund the necessary capital expenditures. The obsolescence of our power and cooling systems and/or our inability to upgrade our data centers, including associated connectivity, could reduce revenue at our data centers and could have a material adverse effect on us. Furthermore, potential future regulations that apply to industries we serve may require customers in those industries to seek specific requirements from their data centers that we are unable to provide. If such regulations were adopted, we could lose customers or be unable to attract new customers in certain industries, which could have a material adverse effect on us. If we are unable to adapt to evolving technologies and customer demands in a timely and cost-effective manner, our ability to sustain and grow our business may suffer. To be successful, we must adapt to our rapidly changing market by continually improving the performance, features and reliability of our services and modifying our business strategies accordingly, which could cause us to incur substantial costs. We may not be able to adapt to changing technologies in a timely and cost-effective manner, if at all, which would adversely impact our ability to sustain and grow our business. In addition, new technologies have the potential to replace or provide lower cost alternatives to our services. The adoption of such new technologies could render some or all of our services obsolete or unmarketable. We cannot guarantee that we will be able to identify the emergence of all of these new service alternatives successfully, modify our services accordingly, or develop and bring new services to market in a timely and cost-effective manner to address these changes. If and when we do identify the emergence of new service alternatives and introduce new services to market, those new services may need to be made available at lower profit margins than our then-current services. Failure to provide services to compete with new technologies or the obsolescence of our services could lead us to lose current and potential customers or could cause us to incur substantial costs, which would harm our operating results and financial condition. Our introduction of new alternative services that have lower price points than our current offerings may also result in our existing customers switching to the lower cost products, which could reduce our net revenue and have a material adverse effect on our results of operation. We have limited ability to protect our intellectual property rights, and unauthorized parties may infringe upon or misappropriate our intellectual property. Our success depends in part upon our proprietary intellectual property rights, including certain methodologies, practices, tools and technical expertise we utilize in designing, developing, implementing and maintaining applications and processes used in providing our services. We rely on a combination of copyright, trademark, trade secrets and other intellectual property laws, nondisclosure agreements with our employees, customers and other relevant persons and other measures to protect our intellectual property, including our brand identity. Nevertheless, it may be possible for third parties to obtain and use our intellectual property without authorization. The unauthorized use of intellectual property is common in China and enforcement of intellectual property rights by PRC regulatory agencies is inconsistent. As a result, litigation may be necessary to enforce our intellectual property rights. Litigation could result in substantial costs and diversion of our management’s attention and resources, and could disrupt our business, as well as have a material adverse effect on our financial condition and results of operations. Given the relative unpredictability of China’s legal system and potential difficulties in enforcing a court judgment in China, there is no guarantee that we would be able to halt any unauthorized use of our intellectual property in China through litigation. 21 We may be subject to third-party claims of intellectual property infringement. We derive most our revenues in China and use , our figure trademark, in a majority of our services. We have registered the figure trademark in China in several categories that cover our services areas and we plan to register the figure trademark in China in certain additional categories. We have also registered the pure text of “GDS” as a trademark in several categories that cover our services areas, however, a third party has also registered the pure text of “GDS” as a trademark in certain IT-related services. As the services for which the third-party trademark is registered are also IT-related and could be construed as similar to ours in some respects, infringement claims may be asserted against us, and we cannot assure you that a government authority or a court will hold the view that such similarity will not cause confusion in the market. In this case, if we use the pure text of GDS (which we have not registered as a trademark with respect to all services we provide) as our trademark, we may be required to explore the possibility of acquiring this trademark or entering into an exclusive licensing agreement with the third party, which will cause us to incur additional costs. In addition, we may be unaware of intellectual property registrations or applications that purport to relate to our services, which could give rise to potential infringement claims against us. Parties making infringement claims may be able to obtain an injunction to prevent us from delivering our services or using trademark or technology containing the allegedly intellectual property. If we become liable to third parties for infringing upon their intellectual property rights, we could be required to pay a substantial damage award. We may also be subject to injunctions that require us to alter our processes or methodologies so as not to infringe upon a third party’s intellectual property, which may not be technically or commercially feasible and may cause us to expend significant resources. Any claims or litigation in this area, whether we ultimately win or lose, could be time-consuming and costly, could cause the diversion of management’s attention and resources away from the operations of our business and could damage our reputation. If our customers’ proprietary intellectual property or confidential information is misappropriated or disclosed by us or our employees in violation of applicable laws and contractual agreements, we could be exposed to protracted and costly legal proceedings and lose clients. We and our employees are in some cases provided with access to our customers’ proprietary intellectual property and confidential information, including technology, software products, business policies and plans, trade secrets and personal data. Many of our customer agreements require that we do not engage in the unauthorized use or disclosure of such intellectual property or information and that we will be required to indemnify our customers for any loss they may suffer as a result. We use security technologies and other methods to prevent employees from making unauthorized copies, or engaging in unauthorized use or unauthorized disclosure, of such intellectual property and confidential information. We also require our employees to enter into nondisclosure arrangements to limit access to and distribution of our customers’ intellectual property and other confidential information as well as our own. However, the steps taken by us in this regard may not be adequate to safeguard our customers’ intellectual property and confidential information. Moreover, most of our customer agreements do not include any limitation on our liability with respect to breaches of our obligation to keep the intellectual property or confidential information we receive from them confidential. In addition, we may not always be aware of intellectual property registrations or applications relating to source codes, software products or other intellectual property belonging to our customers. As a result, if our customers’ proprietary rights are misappropriated by us or our employees, our customers may consider us liable for such act and seek damages and compensation from us. Assertions of infringement of intellectual property or misappropriation of confidential information against us, if successful, could have a material adverse effect on our business, financial condition and results of operations. Protracted litigation could also result in existing or potential customers deferring or limiting their purchase or use of our services until resolution of such litigation. Even if such assertions against us are unsuccessful, they may cause us to lose existing and future business and incur reputational harm and substantial legal fees. We rely on third-party suppliers for key elements of our facilities, equipment, network infrastructure and software. We contract with third parties for the supply of facilities, equipment and hardware that we use in the provision of our services to our customers and that we sell to our customers in some cases. The loss of a significant supplier could delay expansion of the data center facilities that we operate, impact our ability to sell our services and hardware and increase our costs. If we are unable to purchase the hardware or obtain a license for the software that our services depend on, our business could be significantly and adversely affected. In addition, if our suppliers are unable to provide products that meet evolving industry standards or that are unable to effectively interoperate with other products or services that we use, then we may be unable to meet all or a portion of our customer service commitments, which could materially and adversely affect our results of operations. 22 We engage third-party contractors to carry out various services relating to our data center facilities. We engage third-party contractors to carry out various services relating to our data center facilities, including on-site security, cleaning and greening service, part of the 24/7 on duty operations and IT and customer service delivery. We endeavor to engage third- party companies with a strong reputation and proven track record, high-performance reliability and adequate financial resources. However, any such third-party contractor may still fail to provide satisfactory security services or quality outsourced labor, resulting in inappropriate access to our facilities or IT faults which, though non-critical, may cause poor service quality to customers. We have expanded in the past and expect to continue to expand in the future through acquisitions of other companies, each of which may divert our management’s attention, result in additional dilution to stockholders or use resources that are necessary to operate our business. In the past, we have grown our business through acquisitions and we expect to continue to evaluate and enter into discussions regarding potential strategic acquisition transactions and alliances to further expand our business, and, from time to time, we may have a number of pending investments and acquisitions that are subject to closing conditions. See “Item 4. Information on the Company— A. History and Development of the Company” for additional details. However, such pending acquisitions are subject to uncertainties and may not be completed due to failure to satisfy all closing conditions as a result of inaccuracy or breach of representations and warranties of, or non-compliance with covenants by, either party or other reasons. If we are presented with appropriate opportunities, we may acquire additional businesses, services, resources, or assets, including data centers, that are complementary to our core business. Our integration of the acquired entities or assets into our business may not be successful and may not enable us to generate the expected revenues or expand into new services, customer segments or operating locations as well as we expect. This would significantly affect the expected benefits of these acquisitions. Moreover, the integration of any acquired entities or assets into our operations could require significant attention from our management. The diversion of our management’s attention and any difficulties encountered in any integration process could have an adverse effect on our ability to manage our business. In addition, we may face challenges trying to integrate new operations, services and personnel with our existing operations. Our possible future acquisitions may also expose us to other potential risks, including risks associated with unforeseen or hidden liabilities, litigation, corrupt practices of prior owners, problems with data center design or operation, or other issues not discovered in the due diligence process or addressed through acquisition agreements, the diversion of resources from our existing businesses and technologies, our inability to generate sufficient revenue to offset the costs, expenses of acquisitions and potential loss of, or harm to, relationships with employees and customers as a result of our integration of new businesses. Our failure to address these risks or other problems encountered in connection with our past or future acquisitions and investments could cause us to fail to realize the anticipated benefits of these acquisitions or investments, cause us to incur unanticipated liabilities and harm our business generally. Future acquisitions could also result in the use of substantial amounts of our cash and cash equivalents, dilutive issuances of our equity securities, the incurrence of debt, contingent liabilities, amortization expenses or the write-off of goodwill, any of which could harm our financial condition. Also, the anticipated benefits of any acquisitions may not materialize, may be less beneficial, or may develop more slowly, than we expect. If we do not receive the benefits anticipated from these acquisitions and investments, or if the achievement of these benefits is delayed, our operating results may be adversely affected and our stock price could decline. The anticipated benefits of the joint venture cooperation may not be fully realized, or take longer to realize than expected. We have entered into joint venture cooperations with some partners, such as our strategic cooperation with GIC, Shanghai Yan Hua Data Technology Co., Ltd and Shanghai Yue Ang Enterprise Management Consulting Center. See "Item 4. Information on the Company-A. History and Development of the Company" for additional details. We may continue to evaluate and establish potential strategic joint venture cooperations with other appropriate partners to further develop our business. We may not realize all of the anticipated benefits from the joint venture. The success of the joint venture will depend, in part, on the successful partnership between the relevant partner and us. Such a partnership is subject to the risks outlined below and more generally, to the same types of business risks as would impact our business operations when pursued on a cooperative basis. A failure to successfully partner, or a failure to realize our expectations for the joint venture, could materially impact our business, financial condition and results of operations. we may not have the right to exercise sole decision-making authority regarding the joint venture; 23 our partner may become bankrupt or fail to pay the relevant consideration for the cooperation with us; our partner’s interests may not be aligned with our interests, our partner may have economic, tax or other business interests or goals which are inconsistent with our business interests or goals, and may take actions contrary to our policies or objectives; our partner may take actions unrelated to our business agreement but which reflect adversely on us because of our joint venture; disputes between us and our partner may result in litigation or arbitration that would increase our expenses and prevent our management from focusing their time and effort on our business; and we may in certain circumstances be liable for the actions of our partner or guarantee all or a portion of the joint venture's liabilities. The uncertain economic environment may have an adverse impact on our business and financial condition. The uncertain economic environment could have an adverse effect on our liquidity. While we believe we have a strong customer base, if the current market conditions were to worsen, some of our customers may have difficulty paying us and we may experience increased churn in our customer base and reductions in their commitments to us. We may also be required to make allowances for doubtful accounts and our results would be negatively impacted. Our sales cycle could also be lengthened if customers reduce spending on, or delay decision-making with respect to, our services, which could adversely affect our revenue growth and our ability to recognize net revenue. We could also experience pricing pressure as a result of economic conditions if our competitors lower prices and attempt to lure away our customers with lower cost solutions. Finally, our ability to access the equity and debt capital markets may be severely restricted at a time when we would like, or need, to do so, especially during times of increased volatility in global financial markets and stock markets, which could limit our ability to raise funds through additional equity sales. Any inability to raise funds from capital markets generally, and equity capital markets in particular, could adversely affect our liquidity as well as hinder our ability to pursue additional strategic expansion opportunities, execute our business plans and maintain our desired level of revenue growth in the future. A downturn in the PRC or global economy could reduce the demand for our services, which could materially and adversely affect our business and financial condition. The global financial markets have experienced significant disruptions between 2008 and 2009 and the United States, Europe and other economies have experienced periods of recessions. The recovery from the economic downturns of 2008 and 2009 has been uneven and is facing new challenges. These include the United Kingdom’s exit from the European Union, the outbreak of a trade war between the PRC and the United States and the imposition of additional tariffs on bilateral imports in 2018 and 2019, the slower growth of the PRC economy since 2012, as well as the outbreak and global spread of a novel strain of coronavirus, or COVID-19, in early 2020, all of which have contributed to uncertainty about the global economy. There is considerable uncertainty over the long- term effects of the expansionary monetary and fiscal policies adopted by the central banks and financial authorities of some of the world’s leading economies, including those of the United States and the PRC. There have been concerns about the economic effects of rising tensions between the PRC and surrounding Asian countries. Economic conditions in the PRC are sensitive to global economic conditions. International conditions and any new or escalating trade war can lead to disruption in our supply chain and higher costs of capital expenditures. There also have been concerns over unrest in the Middle East, Africa and Hong Kong, which have contributed to volatility in financial and other markets. In particular, actual or perceived social unrest in Hong Kong, one of our Tier 1 markets, could result in service interruptions and data losses for our customers as well as equipment damage, which could significantly disrupt the normal business operations of our customers and reduce our net revenue. Furthermore, any further social unrest in Hong Kong could have material and negative impact on the demand in Hong Kong for colocation or managed services, which in turn would materially and adversely affect our business and financial condition. 24 Any disruptions or continuing or worsening slowdown in the global economy or the PRC economy, whether as a result of the COVID-19 pandemic, trade conflicts, or other reasons, could significantly impact and reduce domestic commercial activities in China, which may lead to decreased demand for our colocation or managed services and have a negative impact on our business, financial condition and results of operations. A decrease in economic activity, whether actual or perceived, a further decrease in economic growth rates or an otherwise uncertain economic outlook in China could have a material adverse effect on our customers' expenditures and, as a result, may also adversely affect our business, financial condition and results of operations. Additionally, continued turbulence in the international markets may adversely affect our ability to access the capital markets to meet our liquidity needs. Any periods of continuing or worsening increased or heightened volatility in financial, equity and other markets, particularly due to investor concerns relating to the COVID-19 pandemic, could limit our ability to raise funds, pursue further business expansion and maintain revenue growth. See “—The uncertain economic environment may have an adverse impact on our business and financial condition” above. Changes in international trade or investment policies and barriers to trade or investment, and the ongoing trade conflict, may have an adverse effect on our business and expansion plans. In recent years, international market conditions and the international regulatory environment have been increasingly affected by competition among countries and geopolitical frictions. Changes to national trade or investment policies, treaties and tariffs, fluctuations in exchange rates or the perception that these changes could occur, could adversely affect the financial and economic conditions in the jurisdictions in which we operate, as well as our international and cross-border operations, our financial condition and results of operations. The U.S. administration under President Donald Trump has advocated for and taken steps toward restricting trade in certain goods, particularly from China. For example, in 2018 the United States announced tariffs that applied to products imported from China, totaling approximately US$250 billion, and in May 2019 the United States increased the rate of certain tariffs previously levied on Chinese products from 10% to 25%. In August 2019, the United States announced that it would apply an additional tariff of 10% on the remaining US$300 billion of goods and products coming from China. After several rounds of trade talks between China and the United States, the United States temporarily delayed an increase in tariffs on US$250 billion of products imported from China, and in September and October 2019, the United States announced several tariff exemptions for certain Chinese products. In August 2019, the U.S. Treasury labelled China a currency manipulator and withdrew such designation in January 2020. In addition, the United States is reported to be considering ways to limit U.S. investment portfolio flows into China, though no details in such regard have been officially announced. China and other countries have retaliated and may further retaliate in response to new trade policies, treaties and tariffs implemented by the United States. For instance, in response to the tariffs announced by the United States in May 2018, China imposed retaliatory tariffs on U.S. goods of a similar value, and in response to the tariff announcements by the United States in August 2019, China announced it would stop buying U.S. agricultural products and would not rule out import tariffs on newly purchased U.S. agricultural products. In September 2019, China unveiled several tariff exemptions for U.S. products, including various agricultural products. Even though, in January 2020, the “Phase One” agreement was signed between the United States and China on trade matters, there can be no assurances that the U.S. or China will not increase tariffs or impose additional tariffs in the future. Any further actions to increase existing tariffs or impose additional tariffs could result in an escalation of the trade conflict, may have tremendous negative impact on the economies of not merely the two countries concerned, but the global economy as a whole. If these measures and tariffs affect any of our customers and their business results and prospects, their demand for, or ability to pay for, our data center services may decrease, which would materially and adversely affect our results of operations. In addition, if China were to increase the tariff on any of the items imported by our suppliers and contract manufacturers from the U.S., they might not be able to find substitutes with the same quality and price in China or from other countries. As a result, our costs would increase and our business, financial condition and results of operations would be adversely affected. 25 Export control and economic or trade sanctions could subject us to regulatory investigations or other actions, which could materially and adversely affect our competitiveness and business operations. Recent economic and trade sanctions threatened and/or imposed by the U.S. government on a number of China-based technology companies, including ZTE Corporation, Huawei Technologies Co., Ltd., or Huawei, and certain of their respective affiliates and other China-based technology companies, as well as actions brought against Huawei and related persons by the U.S. and the Canadian governments, have raised further concerns as to whether, in the future, there may be additional regulatory challenges or enhanced restrictions involving other China-based technology companies including us in a wide range of areas such as data security, artificial intelligence, technologies deployed for surveillance purposes, import/export of technology or other business activities. For instance, the U.S. government announced several orders effectively barring sales of components and software subject to U.S. export controls to, among others, Huawei and certain other China-based technology companies and their respective affiliates. These restrictions, and similar or more expansive restrictions that may be imposed by the U.S. or other jurisdictions in the future, may materially and adversely affect certain of our customers’ abilities to acquire technologies, systems, devices or components that may be critical to their technology infrastructure, service offerings and business operations, and further cause a turmoil to or industries including telecommunications, information technology infrastructure and consumer electronics, which may, in turn, materially and adversely affect their demand for our services and affect our business, financial condition and results of operations. These restrictions or sanctions, even targeting specific entities unrelated to us, could nevertheless also negatively affect our and our technology partners’ abilities to recruit research and development talent or conduct technological collaboration with scientists and research institutes in the U.S., Europe or other countries, which could significantly harm our competitiveness. There can be no assurance that we will not be affected by current or future export controls or economic and trade sanctions regulations. Such potential restrictions, as well as any associated inquiries or investigations or any other government actions, may be difficult or costly to comply with and may, among other things, delay or impede the development of the technology, products and solutions of our customers, hinder the stability of our customers’ supply chain, and may result in negative publicity, any of which may have a material and adverse effect on our business, financial condition and results of operations. Our success depends to a substantial degree upon our senior management, including Mr. William Wei Huang, and key personnel, and our business operations may be negatively affected if we fail to attract and retain highly competent senior management. We depend to a significant degree on the continuous service of Mr. William Wei Huang, our founder, chairman and chief executive officer, and our experienced senior management team and other key personnel such as project managers and other middle management. If one or more members of our senior management team or key personnel resigns, it could disrupt our business operations and create uncertainty as we search for and integrate a replacement. If any member of our senior management leaves us to join a competitor or to form a competing company, any resulting loss of existing or potential clients to any such competitor could have a material adverse effect on our business, financial condition and results of operations. Additionally, there could be unauthorized disclosure or use of our technical knowledge, practices or procedures by such personnel. We have entered into employment agreements with our senior management and key personnel. We have also entered into confidentiality agreements with our personnel which contain nondisclosure covenants that survive indefinitely as to our trade secrets. Additionally, pursuant to these confidentiality agreements, any inventions and creations of our employees relating to the company’s business that are completed within twelve months after termination of employment shall be transferred to the company without payment of consideration, and the employees shall assist the company in applying for corresponding patents or other rights. However, these employment agreements do not ensure the continued service of these senior management and key personnel, and we may not be able to enforce the confidentiality agreements we have with our personnel. In addition, we do not maintain key man life insurance for any of the senior members of our management team or our key personnel. Competition for employees is intense, and we may not be able to attract and retain the qualified and skilled employees needed to support our business. We believe our success depends on the efforts and talent of our employees, including data center design, construction management, operations, engineering, IT, risk management, and sales and marketing personnel. Our future success depends on our continued ability to attract, develop, motivate and retain qualified and skilled employees. Competition for highly skilled personnel is extremely intense. We may not be able to hire and retain these personnel at compensation levels consistent with our existing compensation and salary structure. Some of the companies with which we compete for experienced employees have greater resources than we have and may be able to offer more attractive terms of employment. 26 In addition, we invest significant time and expenses in training our employees, which increases their value to competitors who may seek to recruit them. If we fail to retain our employees, we could incur significant expenses in hiring and training their replacements, and the quality of our services and our ability to serve our customers could diminish, resulting in a material adverse effect to our business. Our operating results may fluctuate, which could make our future results difficult to predict, and may fall below investor or analyst expectations. Our operating results may fluctuate due to a variety of factors, including many of the risks described in this section, which are outside of our control. You should not rely on our operating results for any prior periods as an indication of our future operating performance. Fluctuations in our net revenue can lead to even greater fluctuations in our operating results. Our budgeted expense levels depend in part on our expectations of long-term future net revenue. Given relatively large fixed cost of revenue for services, other than utility costs, any substantial adjustment to our costs to account for lower than expected levels of net revenue will be difficult. Consequently, if our net revenue does not meet projected levels, our operating performance will be negatively affected. If our net revenue or operating results do not meet or exceed the expectations of investors or securities analysts, the price of our ADSs may decline. Declining fixed asset valuations could result in impairment charges, the determination of which involves a significant amount of judgment on our part. Any impairment charge could have a material adverse effect on us. We review our fixed assets for impairment on an annual basis and whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Indicators of impairment include, but are not limited to, a sustained significant decrease in the market price of or the cash flows expected to be derived from a property. A significant amount of judgment is involved in determining the presence of an indicator of impairment. If the total of the expected undiscounted future cash flows is less than the carrying amount of a property on our balance sheet, a loss is recognized for the difference between the fair value and carrying value of the asset. The evaluation of anticipated cash flows requires a significant amount of judgment regarding assumptions that could differ materially from actual results in future periods, including assumptions regarding future occupancy, contract rates and estimated costs to service the contracts. Any impairment charge could have a material adverse effect on us. We may fail to acquire land use rights according to our investment and framework agreements and failure to commence or resume development of land that we have been granted right to use within the required timeframe or to fulfill the investment commitments under the land use right grant contracts and/or investment/framework agreements may cause us to lose such land use rights and subject us to liabilities under land use right grant contracts and investment/framework agreements. We have entered into, and may enter into additional, binding investment and framework agreements to reserve or acquire land use rights. The reservation or acquisition of land use rights under such investment and framework agreements are usually subject to certain grant conditions and subsequently entering into a land use right grant contract through relevant tender, auction or listing-for- sale procedures, and we cannot assure you that all these grant conditions will be satisfied or that ultimately we will be able to enter into the land use right grant contract, or that we will indeed acquire the land use right under the relevant investment and framework agreement. 27 Contracts for the grant of land use rights and some of the investment/framework agreements that we have entered into with the local governments as well as PRC regulations provide for the timeframe within which we are obligated to carry out the construction projects on the land parcels under these contracts and/or agreements. According to the relevant PRC regulations, the PRC government may impose an “idle land fee” equal to 20% of the land fees on land use if the relevant construction land has been identified as “idle land.” The construction land may be identified as “idle land” under any of the following circumstances: (i) where development of and construction on the land fails to commence for more than one year from the construction commencement date prescribed in the land grant contract; or (ii) the development and construction on the land have commenced but have been suspended when the area of the developed land is less than one-third of the total area to be developed or the invested amount is less than 25% of the total amount of investment, and the suspension of development attains for one year. Furthermore, the PRC government has the authority to confiscate any land without compensation if the construction does not commence within two years after the construction commencement date specified in the land grant contract, unless the delay is caused by force majeure, governmental action or preliminary work necessary for the commencement of construction. In addition, these contracts and agreements usually provide for certain investment commitments (such as total investment amount and amount of revenues and taxes generated by the investment projects on the land parcels). We may lose the land use rights and be subject to other liabilities under the land use right grant contracts and the investment/framework agreements if we fail to commence or resume development of land that we have been granted right to use within the required timeframe or to fulfill the investment commitments under the land use right grant contracts and/or investment/framework agreements. We have two parcels of land, one in Chengdu and one in Kunshan, over which we have obtained land use rights, but which may be treated as “idle land” by the respective local government authorities. We suspended the development of one parcel of land in Chengdu after completion of the construction of the then existing buildings thereon in November 2010, and upon such suspension, the area of the developed land was less than one third of the total land area. The development of one parcel of land in Kunshan was not timely commenced before the December 2012 deadline. As of the date of this annual report, we have received approval from the local government authorities to commence construction on the rest of such land parcel in Chengdu and the parcel of land in Kunshan, respectively, and we have commenced construction after receiving such approval. Nonetheless, the local government may treat both the land parcel in Kunshan and the land parcel in Chengdu as being formerly idle land, in which case we may be required to pay idle land fees or penalties, change the planned use of the land, find another parcel of land, or even be required to forfeit the land to PRC government. We may further be subject to penalties for breach of relevant land use right grant contracts and be required to pay damages. We have not been subject to any penalties or required to forfeit any land as a result of failing to commence or resume development or fulfill the relevant investment commitments we made pursuant to the relevant land grant contracts and/or the investment/framework agreements. However, we cannot assure you that we will not be subject to penalties as a result of any failure to commence development or fulfill our investment commitments in accordance with the relevant land grant contracts and/or the investment/framework agreements. If this occurs, our financial condition and results of operations could be materially and adversely affected. We may experience impairment of goodwill in connection with our acquisition of entities. We are required to perform an annual goodwill impairment test. As of December 31, 2019, we carried RMB1,905.8 million (US$273.8 million) of goodwill on our balance sheet. However, goodwill can become impaired. We test goodwill for impairment annually or more frequently if events or changes in circumstances indicate possible impairment, but the fair value estimates involved require a significant amount of difficult judgment and assumptions. We may not achieve the anticipated benefits of the acquisitions, which may result in the need to recognize impairment of some or all of the goodwill we recorded. 28 We are subject to anti-corruption laws of China and Hong Kong as well as the U.S. Foreign Corrupt Practices Act. Our failure to comply with these laws could result in penalties, which could harm our reputation and have an adverse effect on our business, financial condition and results of operations. We operate our business in China and Hong Kong and are thus subject to PRC and Hong Kong laws and regulations related to anti-corruption, which prohibit bribery to government agencies, state or government owned or controlled enterprises or entities, to government officials or officials that work for state or government owned enterprises or entities, as well as bribery to non-government entities or individuals. We are also subject to the U.S. Foreign Corrupt Practices Act, or the FCPA, which generally prohibits companies and any individuals or entities acting on their behalf from offering or making improper payments or providing benefits to foreign officials for the purpose of obtaining or keeping business, along with various other anti-corruption laws. Our existing policies prohibit any such conduct and we have implemented and conducted additional policies and procedures designed, and providing training, to ensure that we, our employees, business partners and other third parties comply with PRC anti-corruption laws and regulations, the FCPA and other anti-corruption laws to which we are subject. There is, however, no assurance that such policies or procedures will work effectively all the time or protect us against liability under the FCPA or other anti-corruption laws. There is no assurance that our employees, business partners and other third parties would always obey our policies and procedures. Further, there is discretion and interpretation in connection with the implementation of PRC anti-corruption laws. We could be held liable for actions taken by our employees, business partners and other third parties with respect to our business or any businesses that we may acquire. We operate in the data center services industry in China and generally purchase our colocation facilities and telecommunications resources from state or government-owned enterprises and sell our services domestically to customers that include state or government-owned enterprises or government ministries, departments and agencies. This puts us in frequent contact with persons who may be considered “foreign officials” under the FCPA, resulting in an elevated risk of potential FCPA violations. If we are found not to be in compliance with PRC anti-corruption laws, the FCPA and other applicable anti-corruption laws governing the conduct of business with government entities, officials or other business counterparties, we may be subject to criminal, administrative, and civil penalties and other remedial measures, which could have an adverse impact on our business, financial condition and results of operations. Any investigation of any potential violations of the FCPA or other anti-corruption laws by U.S., Chinese or Hong Kong authorities or the authorities of any other foreign jurisdictions, could adversely impact our reputation, cause us to lose customer sales and access to colocation facilities and telecommunications resources, and lead to other adverse impacts on our business, financial condition and results of operations. We face risks related to natural disasters, health epidemics and other outbreaks, which could significantly disrupt our operations. On May 12, 2008 and April 14, 2010, severe earthquakes hit part of Sichuan Province in southeastern China and part of Qinghai Province in western China, respectively, resulting in significant casualties and property damage. While we did not suffer any loss or experience any significant increase in cost resulting from these earthquakes, if a similar disaster were to occur in the future that affected our Tier 1 markets or another city where we have data centers or are in the process of developing data centers, our operations could be materially and adversely affected due to loss of personnel and damages to property. In addition, a similar disaster affecting a larger, more developed area could also cause an increase in our costs resulting from the efforts to resurvey the affected area. Even if we are not directly affected, such a disaster could affect the operations or financial condition of our customers and suppliers, which could harm our results of operations. In addition, our business could be materially and adversely affected by other natural disasters, such as snowstorms, typhoon, fires or floods, the outbreak of a widespread health epidemic or pandemic, such as swine flu, avian influenza, severe acute respiratory syndrome, or SARS, Ebola, Zika, COVID-19, or other events, such as wars, acts of terrorism, environmental accidents, power shortage or communication interruptions. If any of our employees is suspected of having contracted any contagious disease, we may under certain circumstances be required to quarantine such employees and the affected areas of our premises. Therefore, we may have to temporarily suspend part of or all of our operations. Furthermore, any future outbreak may restrict economic activities in affected regions, resulting in temporary closure of our offices or prevent us and our customers from traveling. Such closures could severely disrupt our business operations and adversely affect our results of operations. 29 If we fail to maintain proper and effective internal controls, our ability to produce accurate financial statements on a timely basis could be impaired. We are subject to the reporting requirements of the U.S. Securities Exchange Act of 1934, as amended, or the Exchange Act, the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, and the rules and regulations of Nasdaq. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal controls over financial reporting. Commencing with our year ended December 31, 2017, we have been obligated to perform system and process evaluation and testing of our internal controls over financial reporting to allow management to report on the effectiveness of our internal controls over financial reporting in our Form 20-F filing for that year, as required by Section 404 of the Sarbanes-Oxley Act. In addition, as of December 31, 2018, we ceased to be an “emerging growth company” as the term is defined in the JOBS Act, and our independent registered public accounting firm must attest to and report on the effectiveness of our internal control over financial reporting. Even if our management concludes that our internal control over financial reporting is effective, our independent registered public accounting firm, after conducting its own independent testing, may issue a report that is qualified if it is not satisfied with our internal controls or the level at which our controls are documented, designed, operated or reviewed, or if it interprets the relevant requirements differently from us. This will require that we incur substantial additional professional fees and internal costs to expand our accounting and finance functions and that we expend significant management efforts. We continue to enhance our accounting personnel and other resources to address our internal controls and procedures. We also continuously enhance our accounting procedures and internal controls. In addition, our internal control over financial reporting will not prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected. If we are not able to comply with the requirements of Section 404 of the Sarbanes-Oxley Act in a timely manner, or if we are unable to maintain proper and effective internal controls, we may not be able to produce timely and accurate financial statements. If that were to happen, the market price of our ADSs could decline and we could be subject to sanctions or investigations by the SEC, Nasdaq, or other regulatory authorities. 30 Risks Related to Our Corporate Structure If the PRC government deems that the contractual arrangements in relation to our consolidated variable interest entities do not comply with PRC regulatory restrictions on foreign investment in the relevant industries, or if these regulations or the interpretation of existing regulations change in the future, we could be subject to severe penalties or be forced to relinquish our interests in those operations. The PRC government regulates telecommunications-related businesses through strict business licensing requirements and other government regulations. These laws and regulations also include limitations on foreign ownership of PRC companies that engage in telecommunications-related businesses. Specifically, foreign investors are not allowed to own more than a 50% equity interest in any PRC company engaging in value-added telecommunications businesses, with certain exceptions relating to certain categories which do not apply to us. Any such foreign investor must also have experience and a good track record in providing value- added telecommunications services overseas. Because we are a Cayman Islands company, we are classified as a foreign enterprise under PRC laws and regulations, and our wholly owned PRC subsidiaries, GDS (Shanghai) Investment Co., Ltd.(formerly known as “Shanghai Free Trade Zone GDS Management Co., Ltd.”, “GDS Investment Company”), Shanghai Yungang EDC Technology Co., Ltd., Shanghai Wanshu Data Technology Co., Ltd., Shanghai Shuchang Data Science & Technology Co., Ltd., Shanghai Puchang Data Science & Technology Co., Ltd., Shanghai Shuyao Digital Technology Development Co., Ltd., Shanghai Lingying Data Technology Co., Ltd., Shanghai Shuge Data Technology Co., Ltd., Shanghai Shulan Data Science and Technology Co., Ltd., Shanghai Fengtu Data Science & Technology Co.

To comply with PRC laws and regulations, we conduct our business in China through contractual arrangements with our consolidated variable interest entities, or VIEs, and their shareholders. These contractual arrangements provide us with effective control over our consolidated VIEs, namely Shanghai Xinwan Enterprise Management Co., Ltd, or Management HoldCo, GDS Shanghai, GDS Beijing and its subsidiaries, and enable us to receive substantially all of the economic benefits of our consolidated VIEs in consideration for the services provided by our wholly-owned PRC subsidiaries, and have an exclusive option to purchase all of the equity interest in our consolidated VIEs when permissible under PRC laws. For a description of these contractual arrangements, see “Item 4. Information on the Company—C. Organizational Structure—Contractual Arrangements with Our Affiliated Consolidated Entities.” 31 We believe that our corporate structure and contractual arrangements comply with the current applicable PRC laws and regulations. Our PRC legal counsel, based on its understanding of the relevant laws and regulations, is of the opinion that each of the contracts among our wholly-owned PRC subsidiaries, our consolidated VIEs and their shareholders is valid, binding and enforceable in accordance with its terms. However, as there are substantial uncertainties regarding the interpretation and application of PRC laws and regulations, including the Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the M&A Rules, the telecommunications circular described above and the Telecommunications Regulations of the People’s Republic of China, or the Telecommunications Regulations, and the relevant regulatory measures concerning the telecommunications industry, there can be no assurance that the PRC government, such as the MIIT, or other authorities that regulates providers of data center service and other participants in the telecommunications industry would agree that our corporate structure or any of the above contractual arrangements comply with PRC licensing, registration or other regulatory requirements, with existing policies or with requirements or policies that may be adopted in the future. PRC laws and regulations governing the validity of these contractual arrangements are uncertain and the relevant government authorities have broad discretion in interpreting these laws and regulations. If our corporate and contractual structure is deemed by the MIIT, the MOFCOM or other regulators having competent authority to be illegal, either in whole or in part, we may lose control of our consolidated VIEs and have to modify such structure to comply with regulatory requirements. However, there can be no assurance that we can achieve this without material disruption to our business. Further, if our corporate and contractual structure is found to be in violation of any existing or future PRC laws or regulations, the relevant regulatory authorities would have broad discretion in dealing with such violations, including: revoking our business and operating licenses; levying fines on us; confiscating any of our income that they deem to be obtained through illegal operations; shutting down a portion or all of our networks and servers; discontinuing or restricting our operations in China; imposing conditions or requirements with which we may not be able to comply; requiring us to restructure our corporate and contractual structure; restricting or prohibiting our use of the proceeds from overseas offering to finance our PRC consolidated VIEs’ business and operations; and taking other regulatory or enforcement actions that could be harmful to our business. Furthermore, new PRC laws, rules and regulations may be introduced to impose additional requirements that may be applicable to our corporate structure and contractual arrangements. See “—Substantial uncertainties exist with respect to the interpretation and implementation of the newly enacted Foreign Investment Law of the PRC and how it may impact the viability of our current corporate structure, corporate governance and business operations.” Occurrence of any of these events could materially and adversely affect our business, financial condition and results of operations. In addition, if the imposition of any of these penalties or requirement to restructure our corporate structure causes us to lose the rights to direct the activities of our consolidated VIEs or our right to receive their economic benefits, we would no longer be able to consolidate in our consolidated financial statements such VIEs. However, we do not believe that such actions would result in the liquidation or dissolution of our company, our wholly-owned subsidiaries in China or our consolidated VIEs or their subsidiaries. For the years ended December 31, 2017, 2018 and 2019, our consolidated VIEs contributed 91.0%, 97.2% and 97.4%, respectively, of our total net revenue. 32 Our contractual arrangements with our consolidated VIEs may result in adverse tax consequences to us. We could face material and adverse tax consequences if the PRC tax authorities determine that our contractual arrangements with our consolidated VIEs were not made on an arm’s length basis and adjust our income and expenses for PRC tax purposes by requiring a transfer pricing adjustment. A transfer pricing adjustment could adversely affect us by (i) increasing the tax liabilities of our consolidated VIEs without reducing the tax liability of our subsidiaries, which could further result in late payment fees and other penalties to our consolidated VIEs for underpaid taxes; or (ii) limiting the ability of our consolidated VIEs to obtain or maintain preferential tax treatments and other financial incentives. We rely on contractual arrangements with our consolidated VIEs and their shareholders for our China operations, which may not be as effective as direct ownership in providing operational control and otherwise have a material adverse effect as to our business. We rely on contractual arrangements with our consolidated VIEs and their shareholders to operate our business in China. The shareholders of GDS Beijing and GDS Shanghai were Mr. William Wei Huang, our founder, chairman and chief executive officer, and his relative. As previously disclosed, in order to further improve our control over our variable interest entities, reduce key man risks associated with having certain individuals be the equity holders of the variable interest entities, and address the uncertainty resulting from any potential disputes between us and the individual equity holders of the variable interest entities that may arise, as of the date of this annual report, we have completed enhancing the structure of our variable interest entities and certain other variable interest entities, or the VIE Enhancement. As part of the VIE Enhancement, the entire equity interests of GDS Beijing and GDS Shanghai have been transferred from Mr. William Wei Huang and his relative to a newly established holding company, Management HoldCo. The entire equity interest in Management HoldCo is held by a number of management personnel designated by our board of directors. In conjunction with the transfer of legal ownership, GDS Investment Company, one of our subsidiaries, entered into a series of contractual arrangements with Management HoldCo, its shareholders, GDS Beijing and GDS Shanghai to replace the previous contractual arrangements with GDS Beijing and GDS Shanghai on substantially the same terms under such previous contractual arrangements. We also replaced the sole director of GDS Shanghai and certain subsidiaries of GDS Beijing with a board of three directors. Mr. William Wei Huang acts as the chairman of the board of directors of Management HoldCo, GDS Investment Company, GDS Beijing, and certain subsidiaries of GDS Beijing and GDS Shanghai, respectively. Other management members of us and board appointees serve as directors and officers of Management HoldCo, GDS Investment Company, GDS Beijing, and certain subsidiaries of GDS Beijing and GDS Shanghai. For a description of the abovementioned contractual arrangements, see “Item 4. Information on the Company— C. Organizational Structure—Contractual Arrangements with Our Affiliated Consolidated Entities.” In 2017, 2018 and 2019, 91.0%, 97.2% and 97.4%, of our total net revenue, respectively, were attributed to our consolidated VIEs. See “Item 4. Information on the Company—A. History and Development of the Company.” These contractual arrangements may not be as effective as direct ownership in providing us with control over our consolidated VIEs. If our consolidated VIEs or their shareholders fail to perform their respective obligations under these contractual arrangements, our recourse to the assets held by our consolidated VIEs is indirect and we may have to incur substantial costs and expend significant resources to enforce such arrangements in reliance on legal remedies under PRC law. These remedies may not always be effective, particularly in light of uncertainties in the PRC legal system. Furthermore, in connection with litigation, arbitration or other judicial or dispute resolution proceedings, assets under the name of any of record holder of equity interest in our consolidated VIEs, including such equity interest, may be put under court custody. As a consequence, we cannot be certain that the equity interest will be disposed pursuant to the contractual arrangement or ownership by the record holder of the equity interest. All of these contractual arrangements are governed by PRC law and provide for the resolution of disputes through arbitration in the PRC. Accordingly, these contracts would be interpreted in accordance with PRC laws and any disputes would be resolved in accordance with PRC legal procedures. The legal environment in the PRC is not as developed as in other jurisdictions, such as the United States. As a result, uncertainties in the PRC legal system could limit our ability to enforce these contractual arrangements. In the event that we are unable to enforce these contractual arrangements, or if we suffer significant time delays or other obstacles in the process of enforcing these contractual arrangements, it would be very difficult to exert effective control over our consolidated VIEs, and our ability to conduct our business and our financial conditions and results of operation may be materially and adversely affected. See “—Risks Related to Doing Business in the People’s Republic of China—There are uncertainties regarding the interpretation and enforcement of PRC laws, rules and regulations.” 33 The individual management shareholders of our Management HoldCo may have potential conflicts of interest with us, which may materially and adversely affect our business and financial condition. In connection with our operations in China, we rely on the individual management shareholders of our Management HoldCo to abide by the obligations under such contractual arrangements. In particular, GDS Beijing and GDS Shanghai are wholly-owned by Management HoldCo, which, as of the date of this annual report, is in turn owned by five individual management shareholders designated by our board, each holding 20% equity interest in Management HoldCo, namely Yilin Chen (senior vice president, product and service), Yan Liang (senior vice president, operation and delivery), Liang Chen (senior vice president, data center design), Andy Wenfeng Li (general counsel, compliance officer, and company secretary) and Qi Wang (head of cloud and network business) (together referred as “Individual Management Shareholders”). The interests of such Individual Management Shareholders in their individual capacities as the shareholders of Management HoldCo may differ from the interests of our company as a whole, as what is in the best interests of Management HoldCo, including matters such as whether to distribute dividends or to make other distributions to fund our offshore requirement, may not be in the best interests of our company. There can be no assurance that when conflicts of interest arise, any or all of these individuals will act in the best interests of our company or that conflicts of interest will be resolved in our favor. In addition, these individuals may breach or cause our consolidated VIEs and their subsidiaries to breach or refuse to renew the existing contractual arrangements with us. Currently, we do not have arrangements to address potential conflicts of interest the shareholders of Management HoldCo may encounter, on one hand, and as a beneficial owner of our company, on the other hand; provided that we could, at all times, exercise our option under the exclusive call option agreements to cause them to transfer all of their equity ownership in Management HoldCo to a PRC entity or individual designated by us as permitted by the then applicable PRC laws. In addition, if such conflicts of interest arise, we could also, in the capacity of attorney-in-fact of the then existing shareholders of Management HoldCo as provided under the shareholder voting rights proxy agreements, directly appoint new directors of Management HoldCo. We rely on the shareholders of our consolidated VIEs to comply with PRC laws and regulations, which protect contracts and provide that directors and executive officers owe a duty of loyalty to our company and require them to avoid conflicts of interest and not to take advantage of their positions for personal gains, and the laws of the Cayman Islands, which provide that directors and executive officers have a duty of care and a duty of loyalty to act honestly in good faith with a view to our best interests. However, the legal frameworks of China and Cayman Islands do not provide guidance on resolving conflicts in the event of a conflict with another corporate governance regime. If we cannot resolve any conflicts of interest or disputes between us and the shareholders of our consolidated VIEs, we would have to rely on legal proceedings, which could result in disruption of our business and subject us to substantial uncertainty as to the outcome of any such legal proceedings. In order to enhance corporate governance and facilitate administration of its VIEs, we have also replaced the sole director of GDS Shanghai and certain subsidiaries of GDS Beijing with a board of three directors. Mr. William Wei Huang acts as the chairman of the board of directors of Management HoldCo, GDS Investment Company, GDS Beijing , and certain subsidiaries of GDS Beijing and GDS Shanghai, respectively. Other management members of us and board appointees serve as directors and officers of Management HoldCo., GDS Investment Company, GDS Beijing, and certain subsidiaries of GDS Beijing and GDS Shanghai. These enhancements to the corporate governance and management of our VIEs may help to mitigate some of the conflict of interest and other risks detailed above, however we cannot assure you that the enhancements will be effective in preventing or mitigating such risks. Our corporate actions are substantially controlled by our principal shareholders, including our founder, chairman and chief executive officer, Mr. William Wei Huang, who have the ability to control or exert significant influence over important corporate matters that require approval of shareholders, which may deprive you of an opportunity to receive a premium for your ADSs and materially reduce the value of your investment. Our amended articles of association provide that Class B ordinary shares are entitled to 20 votes per share at general meetings of our shareholders with respect to the election of a simple majority of our directors. Mr. William Wei Huang beneficially owns 100% of the Class B ordinary shares issued and outstanding, and any additional Class A ordinary shares which are acquired by the Class B shareholders will be converted into Class B ordinary shares. In addition, for so long as there are Class B ordinary shares outstanding, the Class B shareholders are entitled (i) to nominate one less than a simple majority, or five, of our directors, and (ii) to have 20 votes per share with respect to the election and removal of a simple majority, or six, of our directors. In addition, our amended articles of association provide that STT GDC Pte Ltd, or STT GDC (a wholly owned subsidiary of Singapore Technologies Telemedia Pte Ltd, or ST Telemedia), has the right to appoint up to three directors to our board of directors for so long as they beneficially own certain percentages of our issued share capital. Such appointments will not be subject to a vote by our shareholders. See “Item 6. Directors, Senior Management and Employees—C. Board Practices—Appointment, Nomination and Terms of Directors.” 34 Furthermore, as of December 31, 2019, two of our principal shareholders—STT GDC and Mr. William Wei Huang, our founder, chairman and chief executive officer—beneficially owned approximately 38.3 % of our outstanding Class A ordinary shares and 100% of our outstanding Class B ordinary shares, respectively. On matters where Class A and Class B ordinary shares vote on a 1:1 basis, STT GDC exercises 35.1% of the aggregate voting power. On matters where Class A and Class B ordinary shares vote on a 1:20 basis, Mr. William Wei Huang exercises 54.2% of the aggregate voting power. As a result of these appointment rights, nomination rights, dual-class ordinary share structure and ownership concentration, these shareholders have the ability to control or exert significant influence over important corporate matters, investors may be prevented from affecting important corporate matters involving our company that require approval of shareholders, including: the composition of our board of directors and, through it, any determinations with respect to our operations, business direction and policies, including the appointment and removal of officers; any determinations with respect to mergers or other business combinations; our disposition of substantially all of our assets; and any change in control. These actions may be taken even if they are opposed by our other shareholders, including the holders of the ADSs. Furthermore, this concentration of ownership may also discourage, delay or prevent a change in control of our company, which could have the dual effect of depriving our shareholders of an opportunity to receive a premium for their shares as part of a sale of our company and reducing the price of the ADSs. As a result of the foregoing, the value of your investment could be materially reduced. If the custodians or authorized users of our controlling non-tangible assets, including chops and seals, fail to fulfill their responsibilities, or misappropriate or misuse these assets, our business and operations may be materially and adversely affected. Under PRC law, legal documents for corporate transactions, including agreements and contracts such as the leases and sales contracts that our business relies on, are executed using the chop or seal of the signing entity or with the signature of a legal representative whose designation is registered and filed with the relevant local branch of the State Administration for Industry and Commerce, or the SAIC. We generally execute legal documents by affixing chops or seals, rather than having the designated legal representatives sign the documents. We have three major types of chops—corporate chops, contract chops and finance chops. We use corporate chops generally for documents to be submitted to government agencies, such as applications for changing business scope, directors or company name, and for legal letters. We use contract chops for executing leases and commercial, contracts. We use finance chops generally for making and collecting payments, including, but not limited to issuing invoices. Use of corporate chops and contract chops must be approved by our legal department and administrative department, and use of finance chops must be approved by our finance department. The chops of our subsidiaries and consolidated VIEs are generally held by the relevant entities so that documents can be executed locally. Although we usually utilize chops to execute contracts, the registered legal representatives of our subsidiaries and consolidated VIEs have the apparent authority to enter into contracts on behalf of such entities without chops, unless such contracts set forth otherwise. In order to maintain the physical security of our chops, we generally have them stored in secured locations accessible only to the designated key employees of our legal, administrative or finance departments. Our designated legal representatives generally do not have access to the chops. Although we have approval procedures in place and monitor our key employees, including the designated legal representatives of our subsidiaries and consolidated VIEs, the procedures may not be sufficient to prevent all instances of abuse or negligence. There is a risk that our key employees or designated legal representatives could abuse their authority, for example, by binding our subsidiaries and consolidated VIEs with contracts against our interests, as we would be obligated to honor these contracts if the other contracting party acts in good faith in reliance on the apparent authority of our chops or signatures of our legal representatives. If any designated legal representative obtains control of the chop in an effort to obtain control over the relevant entity, we would need to have a shareholder or board resolution to designate a new legal representative and to take legal action to seek the return of the chop, apply for a new chop with the relevant authorities, or otherwise seek legal remedies for the legal representative’s misconduct. If any of the designated legal representatives obtains and misuses or misappropriates our chops and seals or other controlling intangible assets for whatever reason, we could experience disruption to our normal business operations. We may have to take corporate or legal action, which could involve significant time and resources to resolve while distracting management from our operations, and our business and operations may be materially and adversely affected. 35 Substantial uncertainties exist with respect to the interpretation and implementation of the newly enacted Foreign Investment Law of the PRC and how it may impact the viability of our current corporate structure, corporate governance and business operations. On March 15, 2019, the National People's Congress adopted the Foreign Investment Law of the PRC, which became effective on January 1, 2020 and replaced three existing laws regulating foreign investment in China, namely, the Wholly Foreign- Invested Enterprise Law of the PRC, the Sino-Foreign Cooperative Joint Venture Enterprise Law of the PRC and the Sino-Foreign Equity Joint Venture Enterprise Law of the PRC, together with their implementation rules and ancillary regulations. On December 26, 2019, the State Council issued the Regulations on Implementing the Foreign Investment Law of the PRC, which came into effect on January 1, 2020, and replaced the Regulations on Implementing the Sino-Foreign Equity Joint Venture Enterprise Law of the PRC, Provisional Regulations on the Duration of Sino-Foreign Equity Joint Venture Enterprise Law, the Regulations on Implementing the Wholly Foreign-Invested Enterprise Law of the PRC, and the Regulations on Implementing the Sino-Foreign Cooperative Joint Venture Enterprise Law of the PRC. The Foreign Investment Law of the PRC embodies an expected PRC regulatory trend to rationalize its foreign investment regulatory regime in line with prevailing international practice and the legislative efforts to unify the corporate legal requirements for both foreign and domestic investments. However, since it is relatively new, uncertainties still exist in relation to its interpretation and implementation. For example, the Foreign Investment Law of the PRC adds a catch-all clause to the definition of "foreign investment" so that foreign investment, by its definition, includes "investments made by foreign investors in China through other means defined by other laws or administrative regulations or provisions promulgated by the State Council" without further elaboration on the meaning of "other means." It leaves leeway for the future legislations to provide for contractual arrangements as a form of foreign investment. It is therefore uncertain whether our corporate structure will be seen as violating the foreign investment rules as we are currently leveraging the contractual arrangements to operate certain businesses in which foreign investors are prohibited from or restricted to investing. Furthermore, if future legislations mandate further actions to be taken by companies with respect to existing contractual arrangements, we may face substantial uncertainties as to whether we can complete such actions in a timely manner, or at all. If we fail to take appropriate and timely measures to comply with any of these or similar regulatory compliance requirements, our current corporate structure, corporate governance and business operations could be materially and adversely affected. Risks Related to Doing Business in the People’s Republic of China We may be regarded as being non-compliant with the regulations on VATS due to the lack of IDC licenses for which penalties may be assessed that may materially and adversely affect our business, financial condition, growth strategies and prospects. The laws and regulations regarding value-added telecommunications services, or VATS, licenses in the PRC are relatively new and are still evolving, and their interpretation and enforcement involve significant uncertainties. Investment activities in the PRC by foreign investors were principally governed by the Industry Catalog Relating to Foreign Investment, and currently by the Special Administrative Measures (Negative List) for the Access of Foreign Investment, or the Catalog. Industries not included in the Catalog are permitted industries. Industries such as VATS, including IDC services, restrict foreign investment. Specifically, the Administrative Regulations on Foreign-Invested Telecommunications Enterprises restrict the ultimate capital contribution percentage held by foreign investor(s) in a foreign-invested VATS enterprise to 50% or less. See “Item 4. Information on the Company—B. Business Overview—Regulatory Matters—Regulation on Foreign Investment Restrictions” for additional details. Under the Telecommunications Regulations, telecommunications service providers are required to procure operating licenses prior to their commencement of operations. The Administrative Measures for Telecommunications Business Operating License, which took effect on April 10, 2009 and was amended on September 1, 2017, set forth the types of licenses required to provide telecommunications services in China and the procedures and requirements for obtaining such licenses. Before 2013, the definition of the IDC services was subject to interpretation as to whether our services would fall within its scope. In addition, authorities in different localities had different interpretations. According to the Classification Catalogue of Telecommunications Services, or the Telecom Catalogue publicized in February 2003 by the Ministry of Information Industry, or MII, the predecessor of the MIIT, which took effect in April 2003, and our consultations with the MIIT, IDC services should be rendered through the connection with the internet or other public telecommunications networks. 36 On May 6, 2013, the “Q&A on the Application of IDC/ISP Business”, or the Q&A, was published on the website of China Academy of Telecom Research, an affiliate of the MIIT. The Q&A was issued together with the draft revised Telecom Catalogue of the 2013 version, which although not an official law or regulation, reflected the evolving attitude of the MIIT towards the legal requirements as to applications for IDC licenses. A national consulting body and certain telephone numbers, the Designated Numbers, are provided in the Q&A to answer any questions arising from the application of IDC licenses. Since then, even though the definition of IDC services under the Q&A is identical to that under the Telecom Catalogue, whether a business model should be deemed to be IDC services is subject to the unified clarifications under the Q&A and replies obtained from such Designated Numbers, rather than different replies which may be obtained from different officials from MIIT or its local branches. The draft revised Telecom Catalogue did not come into effect until March 2016, when it was further revised to adapt to developments in the telecommunications industry. During such period, we closely followed legislative developments and conducted feasibility studies for restructuring our business. Based on the Q&A and our consultation with both the Designated Numbers and MIIT officials in 2014 and 2015, IDC services which did not utilize public telecommunication networks would also require an IDC license and that IDC services could only be provided by a holder of an IDC license, or a subsidiary of such holder, with the authorization of the holder. GDS Beijing obtained a cross-regional IDC license in November 2013, the scope of which now includes Shanghai, Suzhou, Beijing, Shenzhen, Chengdu, Guangzhou, Zhangjiakou, Langfang and Tianjin. In order to adapt to the new regulatory requirements and address pre-existing customer agreements, we converted GDS Suzhou, into a domestic company wholly owned by GDS Beijing by acquiring all of the equity interests in GDS Suzhou from Further Success Limited, or FSL, a limited liability company established in the British Virgin Islands, in order to enable GDS Suzhou to provide IDC services with the authorization of GDS Beijing, and under the auspices of an IDC license held by GDS Beijing. MIIT approved GDS Beijing’s application to expand its IDC license coverage to include GDS Suzhou and Kunshan Wanyu Data Service Co., Ltd., or Kunshan Wanyu, so that they are now authorized to provide IDC services. As part of the VIE restructuring, we converted and changed the shareholding of Shanghai Waigaoqiao EDC Technology Co, Ltd., or EDC Shanghai Waigaoqiao, in the same way as GDS Suzhou, and MIIT has approved GDS Beijing’s application to expand its IDC license coverage to include EDC Shanghai Waigaoqiao so that EDC Shanghai Waigaoqiao is also authorized to provide IDC services, and MIIT has approved GDS Beijing’s application to expand its IDC license coverage to include Shenzhen Yaode. In addition, with regard to the other WFOEs that have not contributed substantial revenue, we are deliberating different measures to ensure that any business activity that may have to be conducted by IDC license holders will be conducted by our IDC license holders, which are our consolidated VIEs. See “Item 4. Information on the Company—B. Business Overview—Regulatory Matters—Regulations Related to Value-Added Telecommunications Business” for additional details. However, there can be no assurance that our contracts signed before the completion of the VIE restructuring with any of our WFOEs as the service provider will not be deemed as historical non-compliance. If the MIIT regards us as existing in a state of non- compliance, penalties could potentially be assessed against us. It is possible that the amount of any such penalties may be several times more than the net revenue generated from these services. Our business, financial condition, expected growth and prospects would be materially and adversely affected if such penalties were to be assessed upon us. It is also possible that the PRC government may prohibit a non-compliant entity from continuing to carry on its business, which would materially and adversely affect our results of operations, expected growth and prospects. We have learned that the MIIT will not approve any expansion of authorization by an IDC license holder to its subsidiary, and that it will not allow any such subsidiary of an IDC license holder to renew its current authorization in the future. Instead, the MIIT will require subsidiaries of IDC license holders to apply for their own IDC licenses. Although, to our knowledge, such policy is not supported by any published laws or regulations, we have been making efforts to comply with this regulatory development. GDS Suzhou has already obtained its own IDC license in May 2019. Beijing Wan Chang Yun and Shenzhen Yaode have obtained their own IDC license respectively in September and November 2019. The other subsidiaries of our VIEs currently plan to apply for their own IDC licenses in order to continually maintain authorizations to provide IDC services going forward. However, we cannot assure you that we will be able to obtain approvals from the MIIT for their own IDC Licenses in a timely manner or at all, or obtain approvals from the MIIT for an expansion of authorization from GDS Beijing under its IDC license to allow IDC services to be provided by the other subsidiaries of our VIEs, who rely on such authorizations and expansions to provide IDC services, or that we will be able to renew such authorizations and expansions in due course. If any of these situations occur, our business, financial condition, expected growth and prospects would be materially and adversely affected. 37 Some of our consolidated VIEs may be regarded as being non-compliant with the regulations on VATS, due to operating beyond the permitted scope of their IDC licenses. One of our consolidated VIEs, GDS Shanghai, obtained a regional IDC license for the Shanghai area in January 2012. Nevertheless, GDS Shanghai provided IDC services in cities outside of Shanghai, which were beyond the scope of its then-effective IDC license. GDS Shanghai upgraded its IDC license to a cross-regional license in April 2016, according to which GDS Shanghai is allowed to provide IDC services in Beijing, Shanghai, Suzhou, Shenzhen and Chengdu. A subsidiary of one of our consolidated VIEs, GDS Suzhou, was historically authorized to provide general IDC services under the auspices of an IDC license held by GDS Beijing but such authorization approved by MIIT did not include internet resources collaboration services. Nevertheless, GDS Suzhou signed agreements with clients to provide internet resources collaboration services. In 2018, we further expanded GDS Beijing’s authorization to GDS Suzhou so that GDS Suzhou also was allowed to provide internet resources collaboration services. In addition, in 2016, 2017 and 2018, GDS Beijing and GDS Suzhou entered into IDC service agreements with relevant customers, according to which GDS Beijing and GDS Suzhou have been providing IDC services to their respective customers through third-party data centers in Tianjin. In 2017, GDS Beijing entered into an IDC services agreement with a certain customer, according to which GDS Beijing has been providing IDC services since 2018 in our three data centers located at Zhangjiakou, Hebei Province. However, GDS Beijing’s IDC license and its authorization granted to GDS Suzhou have not included the Tianjin and Zhangjiakou areas until 2019, when GDS Beijing has upgraded its IDC license to cover the Zhangjiakou, Langfang and Tianjin areas, and GDS Suzhou has obtained its own IDC license whereby GDS Suzhou is also allowed to provide general IDC services in broad geographic scope including Tianjin and Zhangjiakou. However, although such approvals have been obtained, we cannot assure you that any agreements signed before GDS Beijing and GDS Suzhou obtained such approvals may not be deemed as historical non-compliance. If the MIIT regards GDS Shanghai, GDS Suzhou and GDS Beijing as being historically non-compliant, penalties which could be several times more than the net revenue generated from these services, could potentially be assessed against us, and as a result, our business, financial condition, expected growth and prospects would be materially and adversely affected. It is also possible that the PRC government may prohibit a historically non-compliant entity from continuing to carry on its business, which would materially and adversely affect our results of operations, expected growth and prospects. One of our subsidiaries, GDS (HK) Limited, entered into IDC service agreements with customers outside China, which may be regarded as non-compliance with the regulations on foreign investment restriction and value-added telecommunications services, by providing IDC service without qualification. In 2015 and 2016, GDS (HK) Limited, or GDS HK, which is one of our Hong Kong—incorporated subsidiaries, entered into IDC service agreements with a few customers outside China, while the actual service provider was intended to be GDS Beijing or EDC Shanghai Waigaoqiao. These IDC service agreements may be regarded as non-compliant, because the law prohibits foreign entities providing IDC services in the PRC. As of the date of this annual report, we have amended all of our IDC service agreements to specify GDS Beijing or its subsidiary as the contracting party for such agreements, so that such agreements are, in our belief, compliant. However, we cannot assure you that our IDC service agreements as amended will not be found to be non-compliant. If the MIIT regards such agreements as non-compliant, penalties could potentially be assessed against us, and as a result, our business, financial condition, expected growth and prospects would be materially and adversely affected. We may fail to obtain, maintain and update licenses and permits necessary to conduct our operations in the PRC, and our business may be materially and adversely affected as a result of any changes in the laws and regulations governing the VATS industry in the PRC. There can be no assurance that we will be able to maintain our existing licenses or permits necessary to provide our current IDC services in the PRC, renew any of them when their current term expires, or update existing licenses or obtain additional licenses necessary for our future business expansion. The failure to obtain, retain, renew or update any license or permit generally, and our IDC licenses in particular, could materially and adversely disrupt our business and future expansion plans. 38 For example, the revised Telecom Catalogue came into effect in March 2016 in which the definition of the IDC business also covers the internet resources collaboration services business to reflect the developments in the telecommunications industry in China and covers cloud-based services. Also, in January 2017, the MIIT issued Circular of the Ministry of Industry and Information Technology on Clearing up and Regulating the Internet Access Service Market, or the 2017 MIIT Circular, according to which an enterprise that obtained its IDC license prior to the implementation of the revised Telecom Catalogue and has actually carried out internet resources collaboration services shall make a written commitment to its original license issuing authority before March 31, 2017 to meet the relevant requirements for business licensing and obtain the corresponding telecommunication business license by the end of 2017. The 2017 MIIT Circular also requires that companies providing IDC services shall not construct communication transmission facilities without permission. Although we have successfully expanded the scope of our IDC licenses to cover internet resources collaboration services, fixed network domestic data transmission services and domestic internet virtual private network services as required under the 2017 MIIT Circular, changes in the regulatory environment of this kind can be disruptive to our business as they may require us to modify the way we conduct our business in order to receive licenses or otherwise comply with such requirements. We may also be deemed in non-compliance for failure to update our operation licenses in a timely manner according to such new regulatory requirements. Any such changes could increase our compliance costs, divert management’s attention or interfere with our ability to serve customers, any of which could harm our results of operations and lower the price of our ADSs. In addition, if future PRC laws or regulations governing the VATS industry require that we obtain additional licenses or permits or update existing licenses in order to continue to provide our IDC services, there can be no assurance that we would be able to obtain such licenses or permits or update existing licenses in a timely fashion, or at all. If any of these situations occur, our business, financial condition and prospects would be materially and adversely affected. Third-party data center providers from whom we lease data center capacity on a wholesale basis may fail to maintain licenses and permits necessary to conduct their operations in the PRC, and our business may be materially and adversely affected. As of December 31, 2019, we operated an aggregate net floor area of 9,884 sqm that we lease on a wholesale basis from other data center providers, and which we refer to as our third-party data centers. There can be no assurance that the wholesale data center providers from whom we lease will be able to maintain their existing licenses or permits necessary to provide our current IDC services in the PRC or renew any of them when their current term expires. Their failure to obtain, retain or renew any license or permit generally, and their IDC licenses in particular, could materially and adversely disrupt our business. In addition, if future PRC laws or regulations governing the VATS industry require that the wholesale data center providers from whom we lease obtain additional licenses or permits in order to continue to provide their IDC services, there can be no assurance that they would be able to obtain such licenses or permits in a timely fashion, or at all. If any of these situations occur, our business, financial condition and prospects could be materially and adversely affected. Changes in the political and economic policies of the PRC government may materially and adversely affect our business, financial condition and results of operations and may result in our inability to sustain our growth and expansion strategies. Substantially all of our operations are conducted in the PRC and a substantial majority of our net revenue is sourced from the PRC. Accordingly, our financial condition and results of operations are affected to a significant extent by economic, political and legal developments in the PRC. The PRC economy differs from the economies of most developed countries in many respects, including the extent of government involvement, level of development, growth rate, and control of foreign exchange and allocation of resources. Although the PRC government has implemented measures emphasizing the utilization of market forces for economic reform, the reduction of state ownership of productive assets, and the establishment of improved corporate governance in business enterprises, a substantial portion of productive assets in China is still owned by the government. In addition, the PRC government continues to play a significant role in regulating industry development by imposing industrial policies. The PRC government also exercises significant control over China’s economic growth by allocating resources, controlling payment of foreign currency-denominated obligations, setting monetary policy, regulating financial services and institutions and providing preferential treatment to particular industries or companies. 39 While the PRC economy has experienced significant growth in the past three decades, growth has been uneven, both geographically and among various sectors of the economy. The PRC government has implemented various measures to encourage economic growth and guide the allocation of resources. Some of these measures may benefit the overall PRC economy, but may also have a negative effect on us. Our financial condition and results of operation could be materially and adversely affected by government control over capital investments or changes in tax regulations that are applicable to us. In addition, the PRC government has implemented in the past certain measures to control the pace of economic growth. These measures may cause decreased economic activity, which in turn could lead to a reduction in demand for our services and consequently have a material adverse effect on our businesses, financial condition and results of operations. There are uncertainties regarding the interpretation and enforcement of PRC laws, rules and regulations. Substantially all of our operations are conducted in the PRC, and are governed by PRC laws, rules and regulations. Our PRC subsidiaries and consolidated VIEs are subject to laws, rules and regulations applicable to foreign investment in China. The PRC legal system is a civil law system based on written statutes. Unlike the common law system, prior court decisions may be cited for reference but have limited precedential value. In 1979, the PRC government began to promulgate a comprehensive system of laws, rules and regulations governing economic matters in general. The overall effect of legislation over the past three decades has significantly enhanced the protections afforded to various forms of foreign investment in China. However, China has not developed a fully integrated legal system, and enacted laws, rules and regulations may not sufficiently cover all aspects of economic activities in China or may be subject to significant degrees of interpretation by PRC regulatory agencies. In particular, because these laws, rules and regulations are relatively new, and because of the limited number of published decisions and the nonbinding nature of such decisions, and because the laws, rules and regulations often give the relevant regulator significant discretion in how to enforce them, the interpretation and enforcement of these laws, rules and regulations involve uncertainties and can be inconsistent and unpredictable. In addition, the PRC legal system is based in part on government policies and internal rules, some of which are not published on a timely basis or at all, and which may have a retroactive effect. As a result, we may not be aware of our violation of these policies and rules until after the occurrence of the violation. Any administrative and court proceedings in China may be protracted, resulting in substantial costs and diversion of resources and management attention. Since PRC administrative and court authorities have significant discretion in interpreting and implementing statutory and contractual terms, it may be more difficult to evaluate the outcome of administrative and court proceedings and the level of legal protection we enjoy than in more developed legal systems. These uncertainties may impede our ability to enforce the contracts we have entered into and could materially and adversely affect our business, financial condition and results of operations. Our business operations are extensively impacted by the policies and regulations of the PRC government. Any policy or regulatory change may cause us to incur significant compliance costs. We are subject to extensive national, provincial and local governmental regulations, policies and controls. Central governmental authorities and provincial and local authorities and agencies regulate many aspects of Chinese industries, including, among others and in addition to specific industry-related regulations, the following aspects: construction or development of new data centers or rebuilding or expansion of existing data centers; banking regulations, as a result of the colocation services we provide to banks and financial institutions, including regulations governing the use of subcontractors in the management and maintenance of facilities; environment laws and regulations; security laws and regulations; establishment of or changes in shareholder of foreign investment enterprises; foreign exchange; 40 taxes, duties and fees; customs; land planning and land use rights; energy conservation and emission reduction; and cyber security and information protection laws and regulations, including the Cyber Security Law of the People’s Republic of China, or the Cyber Security Law, and the Administrative Measures for the Graded Protection of Information Security. The liabilities, costs, obligations and requirements associated with these laws and regulations may be material, may delay the commencement of operations at our new data centers or cause interruptions to our operations. Failure to comply with the relevant laws and regulations in our operations may result in various penalties, including, among others the suspension of our operations and thus adversely and materially affect our business, prospects, financial condition and results of operations. Additionally, there can be no assurance that the relevant government agencies will not change such laws or regulations or impose additional or more stringent laws or regulations. For example, see “Item 4. Information on the Company—B. Business Overview—Regulatory Matters—Regulations Related to Information Technology Outsourcing Services Provided to Banking Financial Institutions” for information regarding regulations of banking and financial institutions that outsource their data center services to us, and “—Regulations Related to Land Use Rights” for information regarding restrictions on the new construction or expansion of data centers within the boundaries of the Beijing municipality. Compliance with such laws or regulations may require us to incur material capital expenditures or other obligations or liabilities. Additionally, the Cyber Security Law came into effect on June 1, 2017, which provides certain rules and requirements applicable to network service providers in China. The Cyber Security Law requires network operators to perform certain functions related to cyber security protection and the strengthening of network information management through taking technical and other necessary measures as required by laws and regulations to safeguard the operation of networks, responding to network security effectively, preventing illegal and criminal activities, and maintaining the integrity and confidentiality and usability of network data. In addition, the Cyber Security Law imposes certain requirements on network operators of critical information infrastructure, for example, network operators of critical information infrastructure generally shall, during their operations in the PRC, store the personal information and important data collected and produced within the territory of PRC, and shall perform certain security obligations as required under the Cyber Security Law. However, the Cyber Security Law still leaves a series of gaps to be filled due to the complex and sensitive nature of this regulatory area. While the Cyber Security law sets out a broad set of principles, certain key terms and clauses are uncertain and ambiguous, which appear intended to be clarified through a series of implementing regulations and guidelines to be issued by relevant authorities. For example, implementing regulations dealing with “personal information protection”, “security assessment of cross-border transfer of personal information and important data” and “protection of critical information infrastructure (CII)” are being formulated. Currently, the Cyber Security Law has not directly impacted our operations, but in light of rapid advances in its implementation, we believe the implementation of the Cyber Security Law involves potential risks to our business because we may be deemed as the network operator of critical information infrastructure thereunder. We are in the process of formulating internal rules to comply with the requirements under the Cyber Security Law, including without limitation, the appointment of designated personnel in charge of data protection, the formation of cyber security committee, the release of privacy protection polices and trainings in relation to the transferring of confidential documentation. However, we cannot assure you that the measures we have taken or will take are adequate under the Cyber Security Law. If further changes in our business practices are required under China’s evolving regulatory framework for the protection of information in cyberspace, our business, financial condition and results of operations may be adversely affected. 41 The approval of the China Securities Regulatory Commission, or the CSRC, may be required under a PRC regulation. The regulation also establishes more complex procedures for acquisitions conducted by foreign investors that could make it more difficult for us to grow through acquisitions. On August 8, 2006, six PRC regulatory agencies, including the MOFCOM, the State-Owned Assets Supervision and Administration Commission, or the SASAC, the State Administration of Taxation, or the SAT, the SAIC, the CSRC, and the State Administration of Foreign Exchange, or the SAFE jointly adopted the Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the M&A Rules, which came into effect on September 8, 2006 and were amended on June 22, 2009. The M&A Rules include, among other things, provisions that purport to require that an offshore special purpose vehicle formed for the purpose of an overseas listing of securities in a PRC company obtain the approval of the CSRC prior to the listing and trading of such special purpose vehicle’s securities on an overseas stock exchange. On September 21, 2006, the CSRC published on its official website procedures regarding its approval of overseas listings by special purpose vehicles. However, substantial uncertainty remains regarding the scope and applicability of the M&A Rules to offshore special purpose vehicles. While the application of the M&A Rules remains unclear, we believe, based on the advice of our PRC counsel, King & Wood Mallesons, that the CSRC approval was not required in the context of our initial public offering or follow-on public offerings because we had not acquired any equity interests or assets of a PRC company owned by its controlling shareholders or beneficial owners who are PRC companies or individuals, as such terms are defined under the M&A Rules. There can be no assurance that the relevant PRC government agencies, including the CSRC, would reach the same conclusion as our PRC counsel. If the CSRC or another PRC regulatory body subsequently determines that its approval was needed for our initial public offering or follow-on public offerings or such approval is needed for any future offerings, we may face adverse actions or sanctions by the CSRC or other PRC regulatory agencies. In any such event, these regulatory agencies may impose fines and penalties on our operations in China, limit our operating privileges in China, delay or restrict the repatriation of the proceeds from our initial public offering or follow-on public offerings into the PRC or take other actions that could have a material adverse effect on our business, financial condition, results of operations, reputation and prospects, as well as the trading price of our ADSs. The regulations also established additional procedures and requirements that are expected to make merger and acquisition activities in China by foreign investors more time-consuming and complex, including requirements in some instances that the MOFCOM be notified in advance of any change-of-control transaction in which a foreign investor takes control of a PRC domestic enterprise, or that the approval from the MOFCOM be obtained in circumstances where overseas companies established or controlled by PRC enterprises or residents acquire affiliated domestic companies. We may grow our business in part by acquiring other companies operating in our industry. Complying with the requirements of the new regulations to complete such transactions could be time-consuming, and any required approval processes, including approval from the MOFCOM, may delay or inhibit our ability to complete such transactions, which could affect our ability to expand our business or maintain our market share. See “Item 4. Information on the Company—B. Business Overview—Regulatory Matters—Regulations Related to M&A and Overseas Listings.” PRC regulations relating to investments in offshore companies by PRC residents may subject our PRC-resident beneficial owners or our PRC subsidiaries to liability or penalties, limit our ability to inject capital into our PRC subsidiaries or limit our PRC subsidiaries’ ability to increase their registered capital or distribute profits. SAFE promulgated the Circular on Relevant Issues Concerning Foreign Exchange Control on Domestic Residents’ Offshore Investment and Financing and Roundtrip Investment through Special Purpose Vehicles, or SAFE Circular 37, on July 4, 2014, which replaced the former circular commonly known as “SAFE Circular 75” promulgated by SAFE on October 21, 2005. SAFE Circular 37 requires PRC residents to register with local branches of SAFE in connection with their direct establishment or indirect control of an offshore entity, for the purpose of overseas investment and financing, with such PRC residents’ legally owned assets or equity interests in domestic enterprises or offshore assets or interests, referred to in SAFE Circular 37 as a “special purpose vehicle.” SAFE Circular 37 further requires amendment to the registration in the event of any significant changes with respect to the special purpose vehicle, such as increase or decrease of capital contributed by PRC individuals, share transfer or exchange, merger, division or other material event. In the event that a PRC shareholder holding interests in a special purpose vehicle fails to fulfill the required SAFE registration, the PRC subsidiaries of that special purpose vehicle may be prohibited from making profit distributions to the offshore parent and from carrying out subsequent cross-border foreign exchange activities, and the special purpose vehicle may be restricted in its ability to contribute additional capital into its PRC subsidiary. Moreover, failure to comply with the various SAFE registration requirements described above could result in liability under PRC law for evasion of foreign exchange controls. According to the Notice on Further Simplifying and Improving Policies for the Foreign Exchange Administration of Direct Investment released on February 13, 2015 by SAFE, local banks will examine and handle foreign exchange registration for overseas direct investment, including the initial foreign exchange registration and amendment registration, under SAFE Circular 37 from June 1, 2015. 42 Mr. William Wei Huang has completed the initial SAFE registration pursuant to SAFE Circular 75 in 2012, and is in the process of applying for amendment of such registration. We have notified substantial beneficial owners of ordinary shares who we know are PRC residents of their filing obligation. Nevertheless, we may not be aware of the identities of all of our beneficial owners who are PRC residents. We do not have control over our beneficial owners and there can be no assurance that all of our PRC-resident beneficial owners will comply with SAFE Circular 37 and subsequent implementation rules, and there is no assurance that the registration under SAFE Circular 37 and any amendment will be completed in a timely manner or will be completed at all. The failure of our beneficial owners who are PRC residents to register or amend their foreign exchange registrations in a timely manner pursuant to SAFE Circular 37 and subsequent implementation rules, or the failure of future beneficial owners of our company who are PRC residents to comply with the registration procedures set forth in SAFE Circular 37 and subsequent implementation rules, may subject such beneficial owners or our PRC subsidiaries to fines and legal sanctions. Failure to register or comply with relevant requirements may also limit our ability to contribute additional capital to our PRC subsidiaries and limit our PRC subsidiaries’ ability to distribute dividends to our company. These risks may have a material adverse effect on our business, financial condition and results of operations. Any failure to comply with PRC regulations regarding our employee share incentive plans may subject the PRC plan participants or us to fines and other legal or administrative sanctions. Pursuant to SAFE Circular 37, PRC residents who participate in share incentive plans in overseas non-publicly-listed companies due to their position as director, senior management or employees of the PRC subsidiaries of the overseas companies may submit applications to SAFE or its local branches for the foreign exchange registration with respect to offshore special purpose companies. Our directors, executive officers and other employees who are PRC residents and who were granted options may follow SAFE Circular 37 to apply for the foreign exchange registration before our company became an overseas listed company. Since our company became an overseas listed company upon completion of our initial public offering, we and directors, executive officers and other employees of our PRC subsidiaries and consolidated VIEs and who have been granted options have been subject to the Notice on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plan of Overseas Publicly Listed Company, issued by SAFE in February 2012, or SAFE Circular 7, according to which, among others, employees, directors, supervisors and other management members of PRC companies participating in any stock incentive plan of an overseas publicly listed company who are domestic individuals as defined therein are required to register and make regular periodic filings with SAFE through a domestic qualified agent, which could be a PRC subsidiary of such overseas listed company, and complete certain other procedures. One of our subsidiaries, as the domestic qualified agent, has completed the registration under SAFE Circular 7 for our share incentive plans and we are making efforts to comply with these requirements stipulated in SAFE Circular 7. Failure to complete the SAFE registrations or meet other requirements may subject relevant participants in our share incentive plans to fines and legal sanctions and may also limit the ability to make payment under our share incentive plans or receive dividends or sales proceeds related thereto, or our ability to contribute additional capital into our wholly-foreign owned enterprises in China and limit our wholly-foreign owned enterprises’ ability to distribute dividends to us. We also face regulatory uncertainties that could restrict our ability to adopt additional share incentive plans for our directors and employees under PRC law. The enforcement of the Labor Contract Law of the People’s Republic of China, or the PRC Labor Contract Law, and other labor- related regulations in the PRC may increase our labor costs, impose limitations on our labor practices and adversely affect our business and our results of operations. On June 29, 2007, the Standing Committee of the National People’s Congress of China enacted the PRC Labor Contract Law, which became effective on January 1, 2008 and was amended on December 28, 2012. The PRC Labor Contract Law introduces specific provisions related to fixed-term employment contracts, part-time employment, probation, consultation with labor unions and employee assemblies, employment without a written contract, dismissal of employees, severance, and collective bargaining, which together represent enhanced enforcement of labor laws and regulations. According to the PRC Labor Contract Law, an employer is obliged to sign an unfixed-term labor contract with any employee who has worked for the employer for 10 consecutive years. Further, if an employee requests or agrees to renew a fixed-term labor contract that has already been entered into twice consecutively, the resulting contract must have an unfixed term, with certain exceptions. The employer must pay economic compensation to an employee where a labor contract is terminated or expires in accordance with the PRC Labor Contract Law, except for certain situations which are specifically regulated. In addition, the government has issued various labor-related regulations to further protect the rights of employees. According to such laws and regulations, employees are entitled to annual leave ranging from five to 15 days and are able to be compensated for any untaken annual leave days in the amount of three times their daily salary, subject to certain exceptions. In the event that we decide to change our employment or labor practices, the PRC Labor Contract Law and its implementation rules may also limit our ability to effect those changes in a manner that we believe to be cost-effective. In addition, as the interpretation and implementation of these new regulations are still evolving, our employment practices may not be at all times deemed in compliance with the new regulations. If we are subject to severe penalties or incur significant liabilities in connection with labor disputes or investigations, our business and financial conditions may be adversely affected. 43 We rely to a significant extent on dividends and other distributions on equity paid by our principal operating subsidiaries to fund offshore cash and financing requirements. We are a holding company and rely to a significant extent on dividends and other distributions on equity paid by our principal operating subsidiaries and on remittances from the consolidated VIEs, for our offshore cash and financing requirements, including the funds necessary to pay dividends and other cash distributions to our shareholders, fund inter-company loans, service any debt we may incur outside of China and pay our expenses. When our principal operating subsidiaries or the consolidated VIEs incur additional debt, the instruments governing the debt may restrict their ability to pay dividends or make other distributions or remittances to us. Furthermore, the laws, rules and regulations applicable to our PRC subsidiaries and certain other subsidiaries permit payments of dividends only out of their retained earnings, if any, determined in accordance with applicable accounting standards and regulations. Under PRC laws, rules and regulations, each of our subsidiaries incorporated in China is required to set aside at least 10% of its net income each year to fund certain statutory reserves until the cumulative amount of such reserves reaches 50% of its registered capital. These reserves, together with the registered capital, are not distributable as cash dividends. As a result of these laws, rules and regulations, our subsidiaries incorporated in China are restricted in their ability to transfer a portion of their respective net assets to their shareholders as dividends, loans or advances. As of December 31, 2019, the restricted net assets were RMB7,367.5 million (US$1,058.3 million), which mainly consisted of paid-in registered capital. Our subsidiaries did not have any significant retained earnings available for distribution in the form of dividends as of December 31, 2019. In addition, paid-in registered share capital and capital reserve accounts are also restricted from withdrawal in the PRC, up to the amount of net assets held in each operating subsidiary. Limitations on the ability of VIEs to make remittance to the wholly-foreign owned enterprise and on the ability of our subsidiaries to pay dividends to us could limit our ability to access cash generated by the operations of those entities, including to make investments or acquisitions that could be beneficial to our businesses, pay dividends to our shareholders or otherwise fund and conduct our business. In January 2017, SAFE promulgated the Circular on Further Improving Reform of Foreign Exchange Administration and Optimizing Genuineness and Compliance Verification, or Circular 3, which stipulates several capital control measures with respect to the outbound remittance of profit from domestic entities to offshore entities, including (i) under the principle of genuine transactions, banks shall check board resolutions regarding profit distribution, original copies of tax filing records and audited financial statements; and (ii) domestic entities shall hold income to account for previous years’ losses before remitting any profits. Moreover, pursuant to Circular 3, domestic entities shall make detailed explanations of their sources of capital and utilization arrangements, and provide board resolutions, contracts and other proof when completing the registration procedures in connection with any outbound investment. We may be treated as a resident enterprise for PRC tax purposes under the PRC Enterprise Income Tax Law, and we may therefore be subject to PRC income tax on our global income. Under the PRC Enterprise Income Tax Law and its implementing rules, enterprises established under the laws of jurisdictions outside of China with “de facto management bodies” located in China may be considered PRC tax resident enterprises for tax purposes and may be subject to the PRC enterprise income tax at the rate of 25% on their global income. “De facto management body” refers to a managing body that exercises substantive and overall management and control over the production and business, personnel, accounting books and assets of an enterprise. The SAT issued the Notice Regarding the Determination of Chinese- Controlled Offshore-Incorporated Enterprises as PRC Tax Resident Enterprises on the Basis of De Facto Management Bodies, or Circular 82, on April 22, 2009. Circular 82 provides certain specific criteria for determining whether the “de facto management body” of a Chinese-controlled offshore-incorporated enterprise is located in China. Although Circular 82 only applies to offshore enterprises controlled by PRC enterprises, not those controlled by foreign enterprises or individuals, the determining criteria set forth in Circular 82 may reflect the SAT general position on how the “de facto management body” test should be applied in determining the tax resident status of offshore enterprises, regardless of whether they are controlled by PRC enterprises. If we were to be considered a PRC resident enterprise, we would be subject to PRC enterprise income tax at the rate of 25% on our global income. In such case, our profitability and cash flow may be materially reduced as a result of our global income being taxed under the Enterprise Income Tax Law. We believe that none of our entities outside of China is a PRC resident enterprise for PRC tax purposes. However, the tax resident status of an enterprise is subject to determination by the PRC tax authorities and uncertainties remain with respect to the interpretation of the term “de facto management body.” 44 We may not be able to obtain certain benefits under the relevant tax treaty on dividends paid by our PRC subsidiaries to us through our Hong Kong subsidiary. We are a holding company incorporated under the laws of the Cayman Islands and as such rely on dividends and other distributions on equity from our PRC subsidiaries to satisfy part of our liquidity requirements. Pursuant to the PRC Enterprise Income Tax Law, a withholding tax rate of 10% currently applies to dividends paid by a PRC “resident enterprise” to a foreign enterprise investor, unless any such foreign investor’s jurisdiction of incorporation has a tax treaty with China that provides for preferential tax treatment. Pursuant to the Arrangement between Mainland China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation and Prevention of Fiscal Evasion with Respect to Taxes on Income, such withholding tax rate may be lowered to 5% if a Hong Kong resident enterprise owns no less than 25% of a PRC enterprise. However, the 5% withholding tax rate does not automatically apply and certain requirements must be satisfied, including without limitation that (a) the Hong Kong enterprise must be the beneficial owner of the relevant dividends; and (b) the Hong Kong enterprise must directly hold no less than 25% share ownership in the PRC enterprise during the 12 consecutive months preceding its receipt of the dividends. Dividends payable to our foreign investors and gains on the sale of our ADSs or Class A ordinary shares by our foreign investors may become subject to PRC tax. Under the Enterprise Income Tax Law and its implementation regulations issued by the State Council, a 10% PRC withholding tax , subject to any reduction or exemption set forth in applicable tax treaties or under applicable tax arrangements between jurisdictions, is applicable to dividends payable to investors that are non-resident enterprises, which do not have an establishment or place of business in the PRC or which have such establishment or place of business but the dividends are not effectively connected with such establishment or place of business, to the extent such dividends are derived from sources within the PRC. Similarly, any gain realized on the transfer of ADSs or Class A ordinary shares by such investors is also subject to PRC tax at a current rate of 10%, subject to any reduction or exemption set forth in applicable tax treaties or under applicable tax arrangements between jurisdictions, if such gain is regarded as income derived from sources within the PRC. If we are deemed a PRC resident enterprise, dividends paid on our Class A ordinary shares or ADSs, and any gain realized from the transfer of our Class A ordinary shares or ADSs, would be treated as income derived from sources within the PRC and would as a result be subject to PRC taxation. Furthermore, if we are deemed a PRC resident enterprise, dividends payable to individual investors who are non-PRC residents and any gain realized on the transfer of ADSs or Class A ordinary shares by such investors may be subject to PRC tax at a current rate of 20%, subject to any reduction or exemption set forth in applicable tax treaties or under applicable tax arrangements between jurisdictions. If we or any of our subsidiaries established outside China are considered a PRC resident enterprise, it is unclear whether holders of our ADSs or Class A ordinary shares would be able to claim the benefit of income tax treaties or agreements entered into between China and other countries or areas. If dividends payable to our non-PRC investors, or gains from the transfer of our ADSs or Class A ordinary shares by such investors, are deemed as income derived from sources within the PRC and thus are subject to PRC tax, the value of your investment in our ADSs or Class A ordinary shares may decline significantly. 45 We and our shareholders face uncertainties with respect to indirect transfers of equity interests in PRC resident enterprises or other assets attributed to a Chinese establishment of a non-Chinese company, or immovable properties located in China owned by non-Chinese companies. On February 3, 2015, the SAT issued the Bulletin on Issues of Enterprise Income Tax on Indirect Transfers of Assets by Non- PRC Resident Enterprises, or Bulletin 7, which replaced or supplemented previous rules under the Notice on Strengthening Administration of Enterprise Income Tax for Share Transfers by Non-PRC Resident Enterprises, or Circular 698, issued by the SAT, on December 10, 2009. Pursuant to Bulletin 7, an “indirect transfer” of assets, including equity interests in a PRC resident enterprise, by non-PRC resident enterprises may be recharacterized and treated as a direct transfer of PRC taxable assets if such arrangement does not have a reasonable commercial purpose and was established for the purpose of avoiding payment of PRC enterprise income tax. As a result, gains derived from such indirect transfer may be subject to PRC enterprise income tax. According to Bulletin 7, “PRC taxable assets” include assets attributed to an establishment in China, immoveable properties located in China, and equity investments in PRC resident enterprises, in respect of which gains from their transfer by a direct holder, being a non-PRC resident enterprise, would be subject to PRC enterprise income taxes. When determining whether there is a “reasonable commercial purpose” of the transaction arrangement, features to be taken into consideration include: whether the main value of the equity interest of the relevant offshore enterprise derives from PRC taxable assets; whether the assets of the relevant offshore enterprise mainly consists of direct or indirect investment in China or if its income mainly derives from China; whether the offshore enterprise and its subsidiaries directly or indirectly holding PRC taxable assets have real commercial nature which is evidenced by their actual function and risk exposure; the duration of existence of the business model and organizational structure; the replicability of the transaction by direct transfer of PRC taxable assets; and the tax situation of such indirect transfer and applicable tax treaties or similar arrangements. In respect of an indirect offshore transfer of assets of a PRC establishment, the resulting gain is to be included with the enterprise income tax filing of the PRC establishment or place of business being transferred, and would consequently be subject to PRC enterprise income tax at a rate of 25%. Where the underlying transfer relates to the immoveable properties located in China or to equity investments in a PRC resident enterprise, which is not related to a PRC establishment or place of business of a non-resident enterprise, a PRC enterprise income tax of 10% would apply, subject to available preferential tax treatment under applicable tax treaties or similar arrangements, and the party who is obligated to make the transfer payments has the withholding obligation. Where the payor fails to withhold any or sufficient tax, the transferor shall declare and pay such tax to the tax authority by itself within the statutory time limit. Late payment of applicable tax will subject the transferor to default interest. Bulletin 7 does not apply to transactions of sale of shares by investors through a public stock exchange where such shares were acquired from a transaction through a public stock exchange. On October 17, 2017, the SAT issued the Announcement on Issues Relating to Withholding at Source of Income Tax of Non- resident Enterprises, or SAT Circular 37. SAT Circular 37 supersedes Circular 698 in its entirety, and amends certain provisions in Bulletin 7, but does not touch upon other provisions of Bulletin 7, which remain in full force. SAT Circular 37 purports to clarify certain issues in the implementation of the above regime, by providing, among others, the definitions of equity transfer income and tax basis, the foreign exchange rate to be used in the calculation of withholding amounts and the date of occurrence of the withholding obligation. Specifically, SAT Circular 37 provides that where the transfer income subject to withholding at its source is derived by a non-PRC resident enterprise by way of instalments, the instalments may first be treated as recovery of costs of previous investments; upon recovery of all costs, the tax amount to be withheld shall then be computed and withheld. There is uncertainty as to the application of Bulletin 7 and SAT Circular 37. Bulletin 7 and SAT Circular 37 may be determined by the tax authorities to be applicable to our historical or future offshore restructuring transactions or sale of our shares or ADSs or those of our offshore subsidiaries, with non-resident enterprises being the transferors. We may be subject to filing obligations or taxed as the transferor, or subject to withholding obligations as the transferee, in such transactions. For transfers of our shares or ADSs by investors that are non-PRC resident enterprises, our PRC subsidiaries may be requested to assist with filings under Bulletin 7 and SAT Circular 37. For example, in the past, we acquired EDC Holding Limited, or EDC Holding by issuing shares of GDS Holdings Limited, or GDS Holdings, to its shareholders in exchange for all of the outstanding shares of EDC Holding that were not held by us then. In addition, certain of our direct and indirect shareholders transferred some or all of their equity interest in us through indirect transfers conducted by their respective overseas holding companies which held shares in us. As a result, the transferors and transferees in these transactions, including us may be subject to the tax filing and withholding or tax payment obligation, while our PRC subsidiaries may be requested to assist in the filing. Furthermore, we, our non-resident enterprises and PRC subsidiaries may be required to spend valuable resources to comply with Bulletin 7 and SAT Circular 37 or to establish that we and our non-resident enterprises should not be taxed under Bulletin 7 and SAT Circular 37, for our previous and future restructuring or disposal of shares of our offshore subsidiaries, which may have a material adverse effect on our financial condition and results of operations. 46 Restrictions on currency exchange may limit our ability to utilize our net revenue effectively. Substantially all of our net revenue is denominated in Renminbi. The Renminbi is currently convertible under the “current account”, which includes dividends, trade and service-related foreign exchange transactions, but not under the “capital account”, which includes foreign direct investment and loans, including loans we may secure from our onshore subsidiaries or consolidated VIEs. Currently, certain of our PRC subsidiaries, may purchase foreign currency for settlement of “current account transactions”, including payment of dividends to us, without the approval of SAFE by complying with certain procedural requirements. However, the relevant PRC governmental authorities may limit or eliminate our ability to purchase foreign currencies in the future for current account transactions. Foreign exchange transactions under the capital account remain subject to limitations and require approvals from, or registration with, SAFE and other relevant PRC governmental authorities. Since a significant amount of our future net revenue will be denominated in Renminbi, any existing and future restrictions on currency exchange may limit our ability to utilize net revenue generated in Renminbi to fund our business activities outside of the PRC or pay dividends in foreign currencies to our shareholders, including holders of our ADSs, and may limit our ability to obtain foreign currency through debt or equity financing for our subsidiaries and consolidated VIEs. Fluctuations in exchange rates could result in foreign currency exchange losses and could materially reduce the value of your investment. The value of the Renminbi against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in political and economic conditions and the foreign exchange policy adopted by the PRC government. On July 21, 2005, the PRC government changed its policy of pegging the value of the Renminbi to the U.S. dollar. From December 31, 2015 to December 31, 2016, the Renminbi depreciated approximately 6.7% against the U.S. dollar. In 2017, however, the RMB appreciated approximately 6.7% against the U.S. dollar; and in 2018, the RMB depreciated approximately 5.7% against the U.S. dollar. Starting from the beginning of 2019, the Renminbi has depreciated significantly against the U.S. dollar again. In early August 2019, The People's Bank of China, or the PBOC, set the daily reference rate for the Renminbi at RMB7.0039 to US$1.00, the first time that the exchange rate of Renminbi to U.S. dollar exceeded RMB7.0000 to US$1.00 since 2008. It remains unclear what further fluctuations may occur or what impact this will have on our results of operations. Substantially all of our net revenue and costs are denominated in Renminbi. We are a holding company and we rely on dividends paid by our operating subsidiaries in China for our cash needs. Any significant revaluation of the Renminbi may materially reduce any dividends payable on, our ADSs in U.S. dollars. To the extent that we need to convert U.S. dollars we received from public offerings and issuance of convertible senior notes into Renminbi for our operations, appreciation of the Renminbi against the U.S. dollar would have an adverse effect on the Renminbi amount we would receive. Conversely, if we decide to convert our Renminbi into U.S. dollars for the purpose of making payments for dividends on our Class A ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against the Renminbi would have a negative effect on the U.S. dollar amount. The audit report included in this annual report on Form 20-F is prepared by an auditor who is not inspected by the Public Company Accounting Oversight Board and, as such, our investors are deprived of the benefits of such inspection. Our independent registered public accounting firm that issues the audit report included elsewhere in this annual report on Form 20-F filed with the SEC, as auditors of companies that are traded publicly in the United States and a firm registered with the U.S. Public Company Accounting Oversight Board, or the PCAOB, is required by the laws of the United States to undergo regular inspections by the PCAOB to assess its compliance with the laws of the United States and professional standards. Because our auditors are located in the Peoples’ Republic of China, a jurisdiction where the PCAOB is currently unable to conduct inspections without the approval of the Chinese authorities, our auditors are not currently inspected by the PCAOB. Inspections of other firms that the PCAOB has conducted outside China have identified deficiencies in those firms’ audit procedures and quality control procedures, which may be addressed as part of the inspection process to improve future audit quality. This lack of PCAOB inspections in China prevents the PCAOB from regularly evaluating our auditor’s audits and its quality control procedures. As a result, investors may be deprived of the benefits of PCAOB inspections. 47 The inability of the PCAOB to conduct inspections of auditors in China makes it more difficult to evaluate the effectiveness of our auditor’s audit procedures or quality control procedures as compared to auditors outside of China that are subject to PCAOB inspections. Investors may lose confidence in our reported financial information and procedures and the quality of our financial statements. If additional remedial measures are imposed on the “big four” PRC-based accounting firms, including our independent registered public accounting firm, in administrative proceedings brought by the SEC alleging such firms’ failure to meet specific criteria set by the SEC with respect to requests for the production of documents, we could be unable to timely file future financial statements in compliance with the requirements of the Exchange Act. Starting in 2011 the Chinese affiliates of the “big four” accounting firms, including our independent registered public accounting firm, were affected by a conflict between U.S. and Chinese law. Specifically, for certain U.S. listed companies operating and audited in mainland China, the SEC and the PCAOB sought to obtain from the Chinese accounting firms access to their audit work papers and related documents. The firms were, however, advised and directed that under Chinese law they could not respond directly to the U.S. regulators on those requests, and that requests by foreign regulators for access to such papers in China had to be channeled through the CSRC. In late 2012 this impasse led the SEC to commence administrative proceedings under Rule 102(e) of its Rules of Practice and also under the Sarbanes-Oxley Act against the Chinese accounting firms, including our independent registered public accounting firm. In January 2014, the administrative law judge reached an initial decision to impose penalties on the firms including a temporary suspension of their right to practice before the SEC. The accounting firms filed a petition for review of the initial decision. On February 6, 2015, before a review by the commissioners of the SEC had taken place, the firms reached a settlement with the SEC. Under the settlement, the SEC accepts that future requests by the SEC for the production of documents will normally be made to the CSRC. The firms will receive matching Section 106 requests and are required to abide by a detailed set of procedures with respect to such requests, which in substance require them to facilitate production via the CSRC. If they fail to meet specified criteria, the SEC retains authority to impose a variety of additional remedial measures on the firms depending on the nature of the failure. Remedies for any future noncompliance could include, as appropriate, an automatic six-month bar on a single firm’s performance of certain audit work, commencement of a new proceeding against a firm, or in extreme cases the resumption of the current proceeding against all four firms. Under the terms of the settlement, the underlying proceeding against the four PRC-based accounting firms was deemed dismissed with prejudice four years after entry of the settlement. The four-year mark occurred on February 6, 2019. It is uncertain whether the SEC will further challenge the four PRC-based accounting firms' compliance with U.S. laws in connection with U.S. regulatory requests for audit work papers or if the results of such challenge would result in the SEC imposing penalties such as suspensions. If additional remedial measures are imposed on the Chinese affiliates of the "big four" accounting firms, including our independent registered public accounting firm, we could be unable to timely file future financial statements in compliance with the requirements of the Exchange Act. In the event that the SEC restarts the administrative proceedings, depending upon the final outcome, listed companies in the United States with major PRC operations may find it difficult or impossible to retain auditors in respect of their operations in the PRC, which could result in financial statements being determined to not be in compliance with the requirements of the Exchange Act, including possible delisting. Moreover, any negative news about any such future proceedings against these audit firms may cause investor uncertainty regarding China-based, United States-listed companies and the market price of our ADSs may be adversely affected. In addition, proposed legislation, including the Equitable Act (Ensuring Quality Information and Transparency for Abroad- Based Listings on our Exchanges) and certain other newly introduced bills, also seek to impose requirements that, among other things, foreign issuers that do not make their audit reports subject to PCAOB review within three years would be delisted from American stock exchanges. If our independent registered public accounting firm were denied, even temporarily, the ability to practice before the SEC and we were unable to timely find another registered public accounting firm to audit and issue an opinion on our financial statements, our financial statements could be determined not to be in compliance with the requirements of the Exchange Act. Such a determination could ultimately lead to the delisting of our Class A ordinary shares from Nasdaq or deregistration from the SEC, or both, which would substantially reduce or effectively terminate the trading of our ADSs in the United States. 48 Risks Related to Our ADSs The trading price of our ADSs may be volatile, which could result in substantial losses to you. The trading prices of our ADSs have been, and are likely to continue to be, volatile and could fluctuate widely due to factors beyond our control. This may happen because of broad market and industry factors, like the performance and fluctuation in the market prices or the underperformance or deteriorating financial results of other listed companies based in China. The securities of some of these companies have experienced significant volatility since their initial public offerings, including, in some cases, substantial price declines in the trading prices of their securities. The trading performances of other Chinese companies’ securities after their offerings, including internet and e-commerce companies, may affect the attitudes of investors toward Chinese companies listed in the United States, which consequently may impact the trading performance of our ADSs, regardless of our actual operating performance. In addition, any negative news or perceptions about inadequate corporate governance practices or fraudulent accounting, corporate structure or matters of other Chinese companies may also negatively affect the attitudes of investors towards Chinese companies in general, including us, regardless of whether we have conducted any inappropriate activities. In addition, securities markets may from time to time experience significant price and volume fluctuations that are not related to our operating performance, such as the large decline in share prices in the United States, China and other jurisdictions in late 2008, early 2009, the second half of 2011, in 2015 and early 2020. In the first quarter of 2020 in particular, as business disruptions and the human impact of the COVID-19 pandemic have mounted around the globe, the Nasdaq, the S&P 500 and the Dow Jones Industrial Average all declined by approximately 14%, 20% and 23%, respectively. Any additional volatility or further declines in securities markets, including the Nasdaq, on which our ADSs are listed, may have a material and adverse effect on the trading price of our ADSs. In addition to the above factors, the price and trading volume of our ADSs may be highly volatile due to multiple factors, including the following: regulatory developments affecting us or our industry, customers or suppliers; announcements of studies and reports relating to the quality of our service offerings or those of our competitors; changes in the economic performance or market valuations of other data center services companies; actual or anticipated fluctuations in our quarterly results of operations and changes or revisions of our expected results; changes in financial estimates by securities research analysts; conditions in the market for data center services; announcements by us or our competitors of new product and service offerings, acquisitions, strategic relationships, joint ventures, capital raisings or capital commitments; additions to or departures of our senior management; fluctuations of exchange rates between the RMB and the U.S. dollar; release or expiry of lock-up or other transfer restrictions on our outstanding shares or ADSs; sales or perceived potential sales of additional Class A ordinary shares or ADSs; and attacks by short sellers, including the publication of negative opinions regarding us and our business prospects in order to create negative market momentum and generate profits for themselves after selling a stock short. See “—Techniques employed by short sellers may drive down the market price of our ADSs.” 49 If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, the market price for our ADSs and trading volume could decline. The trading market for our ADSs depends in part on the research and reports that securities or industry analysts publish about us or our business. If research analysts do not establish and maintain adequate research coverage or if one or more of the analysts who covers us downgrades our ADSs or publishes inaccurate or unfavorable research about our business, the market price for our ADSs would likely decline. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which, in turn, could cause the market price or trading volume for our ADSs to decline. Techniques employed by short sellers may drive down the market price of our ADSs. Short selling is the practice of selling securities that the seller does not own but rather has borrowed from a third party with the intention of buying identical securities back at a later date to return to the lender. The short seller hopes to profit from a decline in the value of the securities between the sale of the borrowed securities and the purchase of the replacement shares, as the short seller expects to pay less in that purchase than it received in the sale. As it is in the short seller’s best interests for the price of the stock to decline, many short sellers publish, or arrange for the publication of, negative opinions regarding the relevant issuer and its business prospects in order to create negative market momentum and generate profits for themselves after selling a stock short. These short attacks have, in the past, led to selling of shares in the market. Public companies that have substantially all of their operations in China have been the subject of short selling. Much of the scrutiny and negative publicity has centered on allegations of a lack of effective internal control over financial reporting resulting in financial and accounting irregularities and mistakes, inadequate corporate governance policies or a lack of adherence thereto and, in many cases, allegations of fraud. As a result, many of these companies are now conducting internal and external investigations into the allegations and, in the interim, are subject to shareholder lawsuits and/or SEC enforcement actions. We have in the past been, are currently, and may in the future be, the subject of unfavorable allegations made by a short seller. Any such allegations may be followed by periods of instability in the market price of our ADSs and negative publicity. Regardless of whether such allegations are proven to be true or untrue, it is not clear what effect such negative publicity could have on us, and we could have to expend a significant amount of resources to investigate such allegations and/or defend ourselves. While we would strongly defend against any such short seller attacks, we may be constrained in the manner in which it can proceed against the relevant short seller by principles of freedom of speech, applicable state law or issues of commercial confidentiality. Such a situation could be costly and time-consuming and could distract our management from growing our business. Even if such allegations are ultimately proven to be groundless, allegations against us could severely impact our business operations and stockholders equity, and any investment in our ADSs could be greatly reduced or rendered worthless. Because we do not expect to pay dividends in the foreseeable future, you must rely on price appreciation of our ADSs for return on your investment. We currently intend to retain most, if not all, of our available funds and any future earnings to fund the development and growth of our business. As a result, we do not expect to pay any cash dividends in the foreseeable future. See “Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Dividend Policy and Distributions.” Therefore, you should not rely on an investment in our ADSs as a source for any future dividend income. Our board of directors has complete discretion as to whether to distribute dividends. Even if our board of directors decides to declare and pay dividends, the timing, amount and form of future dividends, if any, will depend on, among other things, our future results of operations and cash flow, our capital requirements and surplus, the amount of distributions, if any, received by us from our subsidiaries, our financial condition, contractual restrictions and other factors deemed relevant by our board of directors. Accordingly, the return on your investment in our ADSs will likely depend entirely upon any future price appreciation of our ADSs. There is no guarantee that our ADSs will appreciate in value or even maintain the price at which you purchased the ADSs. You may not realize a return on your investment in our ADSs and you may even lose your entire investment in our ADSs. 50 Substantial future sales or perceived potential sales of our ADSs in the public market could cause the price of our ADSs to decline. Sales of our ADSs in the public market, or the perception that these sales could occur, could cause the market price of our ADSs to decline significantly. As of the date of this annual report, we have 1,216,432,715 ordinary shares outstanding, comprising 1,148,842,379 Class A ordinary shares (including 41,586,272 Class A ordinary shares held by JPMorgan Chase Bank, N.A., as depositary, which are reserved for future delivery upon exercise or vesting of share awards granted under our share incentive plans) and 67,590,336 Class B ordinary shares. All ADSs representing our Class A ordinary shares sold in our public offerings are freely transferable by persons other than our “affiliates” without restriction or additional registration under the U.S. Securities Act of 1933, as amended, or the Securities Act. All of the other Class A ordinary shares may be available for sale, subject to volume and other restrictions as applicable under Rules 144 and 701 under the Securities Act. Certain major holders of our Class A ordinary shares have the right to cause us to register under the Securities Act the sale of their shares, subject, in some cases, to the applicable lock-up periods in connection with our initial public offering and follow-on public offerings. Registration of these shares under the Securities Act would result in ADSs representing these shares becoming freely tradable without restriction under the Securities Act immediately upon the effectiveness of the registration. Sales of these registered shares in the form of ADSs in the public market could cause the price of our ADSs to decline significantly. We have adopted share incentive plans, under which we have the discretion to grant a broad range of equity-based awards to eligible participants. See “Item 6. Directors, Senior Management and Employees—B. Compensation—Share Incentive Plans.” We intend to register all ordinary shares that we may issue under these share incentive plans. Once we register these ordinary shares, they can be freely sold in the public market in the form of ADSs upon issuance, subject to volume limitations applicable to affiliates. If a large number of our ordinary shares or securities convertible into our ordinary shares are sold in the public market in the form of ADSs after they become eligible for sale, the sales could reduce the trading price of our ADSs and impede our ability to raise future capital. In addition, any ordinary shares that we issue under our share incentive plans would dilute the percentage ownership held by the investors who purchased ADSs. Our dual-class voting structure and concentrated ownership limits your ability to influence corporate matters and could discourage others from pursuing any change of control transactions that holders of our Class A ordinary shares and ADSs may view as beneficial. As discussed under “—Risks Related to Our Corporate Structure—Our corporate actions are substantially controlled by our principal shareholders, including our founder, chairman and chief executive officer, Mr. William Wei Huang, who have the ability to control or exert significant influence over important corporate matters that require approval of shareholders, which may deprive you of an opportunity to receive a premium for your ADSs and materially reduce the value of your investment” above, Mr. William Wei Huang, our founder, chairman and chief executive officer and our other principal shareholders have considerable influence over matters requiring shareholder approval. To the extent that their interests differ from yours, you may be disadvantaged by any action that they may seek to pursue. This concentrated control could also discourage others from pursuing any potential merger, takeover or other change of control transactions, which could have the effect of depriving the holders of our Class A ordinary shares and our ADSs of the opportunity to sell their shares at a premium over the prevailing market price. You, as holders of ADSs, may have fewer rights than holders of our ordinary shares and must act through the depositary to exercise those rights. Holders of ADSs do not have the same rights of our shareholders and may only exercise the voting rights with respect to the underlying Class A ordinary shares in accordance with the provisions of the deposit agreement. Under our amended articles of association, the minimum notice period required to convene a general meeting will be 10 days. When a general meeting is convened, you may not receive sufficient notice of a shareholders’ meeting to permit you to withdraw your Class A ordinary shares to allow you to cast your vote with respect to any specific matter. In addition, the depositary and its agents may not be able to send voting instructions to you or carry out your voting instructions in a timely manner. We will make all reasonable efforts to cause the depositary to extend voting rights to you in a timely manner, but there can be no assurance that you will receive the voting materials in time to ensure that you can instruct the depositary to vote your ADSs. Furthermore, the depositary and its agents will not be responsible for any failure to carry out any instructions to vote, for the manner in which any vote is cast or for the effect of any such vote. As a result, you may not be able to exercise your right to vote and you may lack recourse if your ADSs are not voted as you requested. In addition, in your capacity as an ADS holder, you will not be able to call a shareholders’ meeting. 51 Your right to participate in any future rights offerings may be limited, which may cause dilution to your holdings. We may from time to time distribute rights to our shareholders, including rights to acquire our securities. However, we cannot make rights available to you in the United States unless we register both the rights and the securities to which the rights relate under the Securities Act or an exemption from the registration requirements is available. Under the deposit agreement, the depositary will not make rights available to you unless both the rights and the underlying securities to be distributed to ADS holders are either registered under the Securities Act or exempt from registration under the Securities Act. We are under no obligation to file a registration statement with respect to any such rights or securities or to endeavor to cause such a registration statement to be declared effective and we may not be able to establish a necessary exemption from registration under the Securities Act. Accordingly, you may be unable to participate in our rights offerings and may experience dilution in your holdings. You may not receive cash dividends if the depositary decides it is impractical to make them available to you. The depositary will pay cash dividends on the ADSs only to the extent that we decide to distribute dividends on our ordinary shares or other deposited securities, and we do not have any present plan to pay any cash dividends in the foreseeable future. See “Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Dividend Policy and Distributions.” To the extent that there is a distribution, the depositary of our ADSs has agreed to pay to you the cash dividends or other distributions it or the custodian receives on our ordinary shares or other deposited securities after deducting its fees and expenses. You will receive these distributions in proportion to the number of Class A ordinary shares your ADSs represent. However, the depositary may, at its discretion, decide that it is inequitable or impractical to make a distribution available to any holders of ADSs. For example, the depositary may determine that it is not practicable to distribute certain property through the mail, or that the value of certain distributions may be less than the cost of mailing them. In these cases, the depositary may decide not to distribute such property to you. You may be subject to limitations on transfer of your ADSs. Your ADSs are transferable on the books of the depositary. However, the depositary may close its transfer books at any time or from time to time when it deems expedient in connection with the performance of its duties. In addition, the depositary may refuse to deliver, transfer or register transfers of ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary deems it advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason. Certain judgments obtained against us by our shareholders may not be enforceable. We are a company incorporated under the laws of the Cayman Islands. We conduct our operations outside the United States and substantially all of our assets are located outside the United States. In addition, all of our directors and executive officers and the experts named in this annual report on Form 20-F reside outside the United States, and most of their assets are located outside the United States. As a result, it may be difficult or impossible for you to bring an action against us or against them in the United States in the event that you believe that your rights have been infringed under the U.S. federal securities laws or otherwise. Even if you are successful in bringing an action of this kind, the laws of the Cayman Islands, the PRC or other relevant jurisdiction may render you unable to enforce a judgment against our assets or the assets of our directors and officers. You may face difficulties in protecting your interests, and your ability to protect your rights through U.S. courts may be limited, because we are incorporated under Cayman Islands law. We are an exempted company limited by shares incorporated under the laws of the Cayman Islands. Our corporate affairs are governed by our memorandum and articles of association, the Companies Law (2020 Revision) of the Cayman Islands and the common law of the Cayman Islands. The rights of shareholders to take action against the directors, actions by minority shareholders and the fiduciary duties of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from the common law of England, the decisions of whose courts are of persuasive authority, but are not binding, on a court in the Cayman Islands. The rights of our shareholders and the fiduciary duties of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands has a less developed body of securities laws than the United States. Some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands. In addition, Cayman Islands companies may not have standing to initiate a shareholder derivative action in a federal court of the United States. 52 Shareholders of Cayman Islands exempted companies like us have no general rights under Cayman Islands law to inspect corporate records or to obtain copies of lists of shareholders of these companies. Our directors will have discretion under the post- offering memorandum and articles of association we expect to adopt, to determine whether or not, and under what conditions, our corporate records may be inspected by our shareholders, but are not obliged to make them available to our shareholders. This may make it more difficult for you to obtain the information needed to establish any facts necessary for a shareholder resolution or to solicit proxies from other shareholders in connection with a proxy contest. As a result of all of the above, our public shareholders may have more difficulty in protecting their interests in the face of actions taken by management, members of the board of directors or controlling shareholders than they would as public shareholders of a company incorporated in the United States. Our articles of association contain anti-takeover provisions that could discourage a third party from acquiring us, which could limit our shareholders’ opportunity to sell their shares, including Class A ordinary shares represented by our ADSs, at a premium. We have adopted amended and restated articles of association that contain provisions to limit the ability of others to acquire control of our company or cause us to engage in change-of-control transactions. These provisions could have the effect of depriving our shareholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging third parties from seeking to obtain control of our company in a tender offer or similar transaction. For example, our board of directors has the authority, without further action by our shareholders, to issue preferred shares in one or more series and to fix their designations, powers, preferences, privileges, and relative participating, optional or special rights and the qualifications, limitations or restrictions, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of which may be greater than the rights associated with our ordinary shares, in the form of ADS or otherwise. Preferred shares could be issued quickly with terms calculated to delay or prevent a change in control of our company or make removal of management more difficult. If our board of directors decides to issue preferred shares, the price of our ADSs may fall and the voting and other rights of the holders of our ordinary shares and ADSs may be materially and adversely affected. In addition, our amended articles of association contain other provisions that could limit the ability of third parties to acquire control of our company or cause us to engage in a transaction resulting in a change of control, as defined in our amended articles of association, including: a provision that entitles Class B ordinary shares to 20 votes per share at general meetings of our shareholders with respect to the election of a simple majority of our directors; a provision that entitles Class B shareholders to nominate one less than a simple majority, or five of our directors; a provision that allows one of our principal shareholders to appoint up to three directors to our board of directors for so long as they beneficially own certain percentages of our issued share capital; and a classified board with staggered terms for our directors, which will prevent the replacement of a majority of directors at one time. These provisions could have the effect of depriving our shareholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging third parties from seeking to obtain control of our company in a tender offer or similar transaction. We are a foreign private issuer within the meaning of the rules under the Exchange Act, and as such we are exempt from certain provisions applicable to U.S. domestic public companies. Because we qualify as a foreign private issuer under the Exchange Act, we are exempt from certain provisions of the securities rules and regulations in the United States that are applicable to U.S. domestic issuers, including: the rules under the Exchange Act requiring the filing with the SEC of quarterly reports on Form 10-Q or current reports on Form 8-K; the sections of the Exchange Act regulating the solicitation of proxies, consents, or authorizations in respect of a security registered under the Exchange Act; the sections of the Exchange Act requiring insiders to file public reports of their stock ownership and trading activities and liability for insiders who profit from trades made in a short period of time; and the selective disclosure rules by issuers of material nonpublic information under Regulation FD. 53 We are required to file an annual report on Form 20-F within four months of the end of each fiscal year. In addition, we intend to publish our results on a quarterly basis as press releases, distributed pursuant to the rules and regulations of Nasdaq. Press releases relating to financial results and material events will also be furnished to the SEC on Form 6-K. However, the information we are required to file with or furnish to the SEC will be less extensive and less timely compared to that required to be filed with the SEC by U.S. domestic issuers. As a result, you may not be afforded the same protections or information that would be made available to you were you investing in a U.S. domestic issuer. As a company incorporated in the Cayman Islands, we are permitted to adopt certain home country practices in relation to corporate governance matters that differ significantly from the Nasdaq corporate governance listing standards; these practices may afford less protection to shareholders than they would enjoy if we complied fully with the Nasdaq corporate governance listing standards. As a Cayman Islands company listed on the Nasdaq Global Market, we are subject to the Nasdaq corporate governance listing standards. However, Nasdaq Stock Market Rules permit a foreign private issuer like us to follow the corporate governance practices of its home country. Certain corporate governance practices in the Cayman Islands, which is our home country, may differ significantly from the Nasdaq corporate governance listing standards. For instance, we are not required to: have a majority of the board be independent (although all of the members of the audit committee must be independent under the Exchange Act); have a compensation committee or a nominations or corporate governance committee consisting entirely of independent directors; or have regularly scheduled executive sessions with only independent directors each year. We have relied on and intend to continue to rely on some of these exemptions. As a result, you may not be provided with the benefits of certain corporate governance requirements of Nasdaq. We may become a passive foreign investment company, or PFIC, which could result in adverse United States federal income tax consequences to United States investors. Based on the past and projected composition of our income and assets, and the valuation of our assets, including goodwill, we do not believe we were a PFIC for our most recent taxable year and we do not expect to become one in the future, although there can be no assurance in this regard. The determination of whether or not we are a PFIC is made on an annual basis and will depend on the composition of our income and assets from time to time. Specifically, for any taxable year, we will be classified as a PFIC for United States federal income tax purposes if either (i) 75% or more of our gross income in that taxable year is passive income or (ii) the average percentage of our assets (which includes cash) by value in that taxable year which produce, or are held for the production of, passive income is at least 50%. The calculation of the value of our assets will be based, in part, on the quarterly market value of our ADSs, which is subject to change. See “Item 10. Additional Information—E. Taxation—Material United States Federal Income Tax Considerations—Passive Foreign Investment Company.” In addition, there is uncertainty as to the treatment of our corporate structure and ownership of our consolidated VIEs for United States federal income tax purposes. For United States federal income tax purposes, we consider ourselves to own the stock of our consolidated VIEs. If it is determined, contrary to our view, that we do not own the stock of our consolidated VIEs for United States federal income tax purposes (for instance, because the relevant PRC authorities do not respect these arrangements), we may be treated as a PFIC. If we are a PFIC for any taxable year during which you hold our ADSs or Class A ordinary shares, our PFIC status could result in adverse United States federal income tax consequences to you if you are a United States Holder, as defined under “Item 10. Additional Information-E. Taxation—Material United States Federal Income Tax Considerations.” For example, if we are or become a PFIC, you may become subject to increased tax liabilities under United States federal income tax laws and regulations and will become subject to burdensome reporting requirements. See “Item 10. Additional Information—E. Taxation—Material United States Federal Income Tax Considerations—Passive Foreign Investment Company.” There can be no assurance that we will not be a PFIC for 2020 or any future taxable year. 54 We will continue to incur increased costs as a result of being a public company, particularly since we have ceased to qualify as an “emerging growth company.” Since the completion of our initial public offering, we have incurred significant legal, accounting and other expenses that we did not incur as a private company. The Sarbanes-Oxley Act, as well as rules subsequently implemented by the SEC and Nasdaq, impose various requirements on the corporate governance practices of public companies. Since December 31, 2018, we have been deemed to be a “large accelerated filer” as the term is defined in Rule 12b-2 of the Exchange Act, and we thereby ceased to be an “emerging growth company” as the term is defined in the JOBS Act. These rules and regulations have increased our legal and financial compliance costs and made some corporate activities more time-consuming and costly. Since we have ceased to be an “emerging growth company”, we expect to incur significant expenses and devote substantial management effort toward ensuring compliance with the requirements of Section 404 of the Sarbanes-Oxley Act and the other rules and regulations of the SEC. Operating as a public company has also made it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. In addition, we have incurred additional costs associated with our public company reporting requirements. It may also be more difficult for us to find qualified persons to serve on our board of directors or as executive officers. We are currently evaluating and monitoring developments with respect to these rules and regulations, and we cannot predict or estimate with any degree of certainty the amount of additional costs we may incur or the timing of such costs. Shareholders of our company have in the past brought, and may in the future bring, securities class action lawsuits against our company following periods of instability in the market price of our ADSs. On August 2, 2018, a securities class action lawsuit was filed in the United States District Court in the Eastern District of Texas against GDS Holdings Limited, our Chief Executive Officer Mr. William Wei Huang, and our Chief Financial Officer Mr. Daniel Newman (collectively, “Defendants”) by Hamza Ramzan, a GDS shareholder. See “Item 4. Information on the Company—B. Business Overview—Legal Proceedings.” On April 7, 2020, the court granted Defendants’ motion to dismiss the amended complaint, and dismissed the action in its entirety against all Defendants. The dismissal of the action is not yet final, as Plaintiffs’ time to appeal or seek other relief from the judgment has not yet expired. Any further class action lawsuit could divert a significant amount of our management’s attention and other resources from our business and operations, which could harm our results of operations and require us to incur significant expenses to defend the suit. Any such class action lawsuit, whether or not successful, could harm our reputation and restrict our ability to raise capital in the future. ITEM 4. INFORMATION ON THE COMPANY A. History and Development of the Company We are an exempted company and were incorporated in the Cayman Islands in 2006. We own 100% of the shares in EDC Holding, an exempted company also incorporated in the Cayman Islands, through which we indirectly hold 100% of the equity interests in holding companies in Hong Kong, many of which own our data centers through one or more data center companies. Through EDC Holding we also indirectly hold 100% of the equity interests in GDS Investment Company. 55 Due to PRC regulations that limit foreign equity ownership of entities providing VATS at 50%, and the inclusion of IDC services within the scope of VATS, we conduct a substantial part of our operations in China through contractual arrangements among GDS Investment Company, our data center companies, two VIEs that hold licenses required to operate our business, GDS Beijing and GDS Shanghai and Management HoldCo and its shareholders. As a result of these contractual arrangements, we control Management HoldCo, GDS Shanghai, GDS Beijing and its subsidiaries, and have consolidated the financial information of these VIEs in our consolidated financial statements in accordance with U.S. GAAP. In order to adapt to regulatory requirements and address pre-existing customer agreements, in 2016, as part of a VIE restructuring, we converted GDS Suzhou into a domestic company wholly-owned by GDS Beijing by acquiring all of the equity interests in GDS Suzhou from FSL. MIIT has approved GDS Beijing’s application to expand its IDC license coverage to include GDS Suzhou and Kunshan Wanyu so that they are now authorized to provide IDC services. As part of the VIE restructuring in 2016, we converted and changed the shareholding of EDC Shanghai Waigaoqiao in the same way as GDS Suzhou, and MIIT has approved GDS Beijing’s application to expand its IDC license coverage to include EDC Shanghai Waigaoqiao so that EDC Shanghai Waigaoqiao is also authorized to provide IDC services. MIIT has also approved GDS Beijing’s application to expand its IDC license coverage to include Shenzhen Yaode, the company operating the data center we acquired in the SZ5 acquisition. In addition, with regard to the other WFOEs that have not contributed substantial revenue, we are deliberating different measures to ensure that any business activity that may have to be conducted by IDC license holders will be conducted by our IDC license holders, which are consolidated VIEs. See “Item 4. Information on the Company—B. Business Overview—Regulatory Matters—Regulations Related to Value-Added Telecommunications Business” for additional details. As of the date of this annual report, we conducted the substantial majority of our operations in China through GDS Beijing and its subsidiaries. Accordingly, going forward we expect that substantially all of our net revenue will be generated through our consolidated VIEs, namely Management HoldCo, GDS Shanghai, GDS Beijing and its subsidiaries. Due to PRC regulations that limit foreign equity ownership of entities providing IDC services, we conduct a substantial part of our operations in China through VIEs which are ultimately owned by PRC citizens and licensed or authorized to provide IDC services. To comply with such statutory requirements, as part of the 2016 VIE restructuring, we have also converted some entities which used to be our subsidiaries into subsidiaries of GDS Beijing. In addition, due to the same reason, we have consummated a number of acquisitions of target companies that are licensed or authorized to provide IDC services through our existing VIEs. In order to enhance corporate governance and facilitate administration of the VIEs, we initiated in November 2019, and as of the date of this annual report, have completed a further VIE restructuring and enhancement plan under which we transferred the ownership of the 100% equity interest of GDS Beijing and GDS Shanghai from Mr. William Wei Huang and his relative to a newly established holding company, Management HoldCo, 100% of the equity interest in which is owned by a number of management personnel designated by our board of directors. Currently, there are five individual management shareholders, each holding a 20% equity interest in Management HoldCo, namely Yilin Chen (senior vice president, product and service), Yan Liang (senior vice president, operation and delivery), Liang Chen (senior vice president, data center design), Andy Wenfeng Li (general counsel, compliance officer, and company secretary) and Qi Wang (head of cloud and network business). In conjunction with the transfer of ownership, we have, through GDS Investment Company, entered into a set of contractual arrangements with Management HoldCo, its shareholders, GDS Beijing and GDS Shanghai on substantially the same terms as those under the previous contractual arrangements with GDS Beijing and GDS Shanghai. We have also replaced the sole director of GDS Shanghai and certain subsidiaries of GDS Beijing with a board of three directors. Mr. William Wei Huang acts as the chairman of the board of directors of Management HoldCo, GDS Investment Company, GDS Beijing, and certain subsidiaries of GDS Beijing and GDS Shanghai, respectively. Other management members of us and board appointees serve as directors and officers of Management HoldCo, GDS Investment Company, GDS Beijing, and certain subsidiaries of GDS Beijing and GDS Shanghai. We believe that this restructuring reduces risk by allocating ownership of the VIEs among a larger number of individual management shareholders, and strengthens corporate governance with the establishment of the board of directors in the VIEs and their subsidiaries. We also believe that this restructuring creates a more stable ownership structure by avoiding reliance on a single or small number of natural persons, and by buffering the ownership of the VIEs with an additional layer of legal entities, creating an institutional structure that is tied to our management and culture. 56 We have been advised by our PRC legal counsel, King & Wood Mallesons, that such restructuring does not violate any current applicable PRC laws or regulations. We believe such restructuring would not give rise to any material tax charges and the consolidation of the VIEs will not be affected under the relevant accounting rules. As of the date of this annual report, this restructuring has been completed.

Business Overview We are a leading developer and operator of high-performance data centers in China. Our facilities are strategically located in China’s primary economic hubs where demand for high-performance data center services is concentrated. We also build-to-suit and operate data centers at lower-tier locations selected by our customers in order to fulfill their broader requirements. Our data centers have large net floor area, high power capacity, density and efficiency, and multiple redundancy across all critical systems. We are carrier and cloud-neutral, which enables our customers to access all the major PRC telecommunications networks, as well as the largest PRC and global public clouds which we host in many of our facilities. We offer colocation and managed services, including direct private connection to leading public clouds, an innovative service platform for managing hybrid clouds and, where required, the resale of public cloud services. We have a 19-year track record of service delivery, successfully fulfilling the requirements of some of the largest and most demanding customers for outsourced data center services in China. Our base of 624 customers consists predominantly of hyperscale cloud service providers, large internet companies, financial institutions, telecommunications carriers and IT service providers, and large domestic private sector and multinational corporations. As of December 31, 2019, we had an aggregate net floor area of 225,963 sqm in service, 91.9% of which was committed by customers, and an aggregate net floor area of 89,834 sqm under construction, 63.6% of which was pre-committed by customers, in each case excluding joint venture data centers. As of December 31, 2019, we had an additional aggregate net floor area of approximately 3,900 sqm in service and approximately 7,800 sqm under construction at joint venture data centers, 100% of which was committed or pre-committed by customers. We believe the market for high-performance data center services in China is experiencing strong growth. Demand is driven by the confluence of several secular technological, economic and industry trends, including: rapid growth of the internet, e-commerce, e-payments, cloud computing and big data; rising adoption of new technologies such as 5G, virtual and augmented reality, artificial intelligence, blockchain and the internet of things; increasing criticality of IT and data in the enterprise environment; and growing reliance by enterprises on outsourcing as a solution to the increasing complexity and cost of managing mission-critical IT infrastructure. Demand is also driven by PRC government policies which consistently and actively support technology-driven development and the growth of the digital economy. Recently, the PRC government has promoted the concept of “new infrastructure” which includes, among other things, largescale date centers, artificial intelligence and industrial internet. Such policy orientation is ushering in new waves of investment at all levels of the economy, which we believe will give rise to numerous opportunities we can take advantage of in the years to come. To satisfy this demand requires data centers which are largescale, both in terms of net floor area and power capacity, highly reliable in terms of uptime, and highly efficient in terms of power usage. With increasing scale, it has become increasingly challenging to source, develop and operate new facilities that meet the required standard, in particular to secure suitable land and buildings which can be developed or converted into data center facilities and to obtain the necessary regulatory approvals and power supply. As a result, we believe that there is a relative scarcity of high-performance data center capacity in China. Our portfolio of data centers and secured expansion capacity are strategically located to address this growing demand. We develop and operate our data centers predominantly in and around Shanghai, Beijing, Shenzhen, Guangzhou, Hong Kong , Chengdu and Chongqing, the primary financial, commercial, industrial and communications hubs in each region of China. We refer to the areas in and around these hubs as Tier 1 markets. Our customers typically use our data centers in Tier 1 markets to house their mission- critical, latency-sensitive data and applications. Our data center locations provide convenient access for our customers and, furthermore, the extensive multi-carrier telecommunications networks in these markets enable our customers to enhance the performance and lower the cost of connectivity to our facilities. In the past, our portfolio was mainly concentrated in key urban districts within each Tier 1 market in accordance with customer preference. However, more recently, in order to keep pace with demand and overcome the challenge of creating new supply, we are developing more data centers at strategic locations on the outer edge of these markets, including on campuses where we can expand capacity in multiple phases. These outer edge developments, which we still consider Tier 1 markets, enable our hyperscale customers to fulfill their requirement for larger deployments of IT capacity on a single site and to upscale over time, while remaining within acceptable parameters for network latency. In addition to our presence in Tier 1 markets, we build-to-suit and operate our own data centers and joint venture data centers at campuses in Hebei, Guangdong and Jiangsu Provinces and Inner Mongolia Autonomous Region for one of our largest customers. 62 Our data centers are largescale, highly reliable and highly efficient facilities that provide a flexible, modular and secure operating environment in which our customers can house, power and cool the computer systems and networking equipment that support their mission-critical IT infrastructure. We install large power capacity and optimize power usage efficiency, which enables our customers to deploy their IT infrastructure more efficiently and reduce their operating and capital costs. As a result of our advanced data center design, high technical specifications and robust operating procedures, we are able to make service level commitments related to service availability and other key metrics that meet our customers’ required standards. We currently serve 624 customers, including PRC and global hyperscale cloud service providers and large internet companies, a diverse community of financial institutions, telecommunications carriers and IT service providers and large domestic private sector and multinational corporations, many of which are leaders in their respective industries. We host the largest public cloud platforms operating in China, some of which are present in multiple GDS data centers. Agreements with our hyperscale cloud service provider and large internet customers generally have terms of three to ten years, while agreements with our financial institution and enterprise customers typically have terms of one to five years. As of December 31, 2019, we operated thirty-five self-developed data centers with an aggregate net floor area of 216,079 sqm in service. We also operated capacity at approximately 20 third-party data centers with an aggregate net floor area of 9,884 sqm in service, which we lease on a wholesale basis and use to provide colocation and managed services to our customers. As of the same date, we had a further fourteen new self-developed data centers with an aggregate net floor area of 89,834 sqm under construction. In addition to the above, we also operated one joint venture data center with a net floor area of approximately 3,900 sqm in service, and had two joint venture data centers with an aggregate net floor area of approximately 7,800 sqm under construction. As of the same date, we had an estimated aggregate developable net floor area of approximately 244,794 sqm held for potential future development. Our net revenue and results of operations are largely determined by the degree to which our data center capacity is committed or pre- committed as well as its utilization. We had commitment rates for our area in service (excluding joint venture date centers) of 91.8%, 94.9% and 91.9% as of December 31, 2017, 2018 and 2019, respectively. We had utilization rates for our area in service (excluding joint venture date centers) of 60.9%, 67.6% and 69.0% as of December 31, 2017, 2018 and 2019, respectively. The difference between commitment rate and utilization rate is primarily attributable to customers who have entered into agreements but have not yet started to use revenue-generating services. We have experienced significant growth in recent years. Our net revenue grew from RMB1,616.2 million in 2017 to RMB2,792.1 million in 2018, representing an increase of 72.8%, and increased to RMB4,122.4 million (US$592.1 million) in 2019, representing an increase of 47.6%. Our net loss increased from RMB326.9 million in 2017 to RMB430.3 million in 2018, and increased to RMB442.1 million (US$63.5 million) in 2019. Our adjusted EBITDA increased from RMB512.3 million in 2017 to RMB1,046.5 million 2018, and increased to RMB1,824.0 million (US$262.0 million) in 2019. As of December 31, 2017, 2018 and 2019, our accumulated deficit was RMB1,185.6 million, RMB1,615.1 million and RMB2,057.2 million (US$295.5 million), respectively. Our Business Model and the Data Center Lifecycle Our core business operations entail the planning and sourcing of new data centers, developing such facilities, securing customer commitments, providing our colocation and managed services to customers, and maintaining high levels of service and customer satisfaction to develop and maintain long-term relationships with our customers. We focus on developing and operating what we refer to as high-performance data centers. These are data centers that feature large net floor area, high power capacity, density, and efficiency, and multiple redundancy across all critical systems. Our strong customer and industry relationships afford us insight into the size, timing, and location of future demand which is reflected in our data center capacity development plan. We source new data center capacity by: (i) acquiring or leasing property which we develop for use as data center facilities, whether through constructing on greenfield land, redeveloping brownfield sites, converting existing industrial buildings, or fitting out and equipping purpose-built building shells; (ii) leasing existing data center capacity from third-party wholesale providers; and, (iii) acquiring high performance data centers from other companies. Regardless of the source of our data center capacity, we ensure that the facilities meet the high-performance standards required by our target customers. After procuring greenfield or brownfield sites or existing industrial buildings or purpose-built building shells, we design and, through cooperation with developers, contractors, and suppliers, build out the facility to our advanced design and high technical specifications. 63 We take a modular approach to developing, commissioning, equipping and fitting out of facilities, so that we can cater to a range of customer requirements with regard to redundancy, power density, cooling, rack configuration and other technical specifications. In addition, by taking a modular approach, we are able to phase our capital expenditures related to equipping and fitting out individual computer rooms in accordance with proven sales demand or contractual delivery commitments to customers. We usually commence marketing new data center facilities before we commence construction. We aim to secure pre- commitments from customers for a portion of the area under construction, typically from anchor customers who require largescale capacity, such as hyperscale cloud service providers and large internet companies. Through securing such pre-commitments, we are able to reduce investment risk and optimize resource planning. Due to the strength of demand, in some cases we deliberately do not seek pre-commitments, in order to hold back sufficient capacity for our financial institution and large enterprise customers who typically procure with a shorter lead time once data centers are in service. Our agreements provide flexibility to our customers with regard to utilization and the commencement of billing. Anchor customers with largescale commitments typically move in over 12 to 24 months, whereas financial institutions and large enterprise customers typically move in over a period of three to six months. During the period when customers are moving into our data centers, we bill our customers for services based on the higher of their actual utilization of the capacity and the minimum utilization commitments stated in the customer agreements. Once data center capacity becomes billable in accordance with the terms of customer agreements remaining in effect, customers are charged a fixed amount for services based on the capacity which is committed to them. In agreements for a substantial majority of our capacity, customers are also charged separately for actual power consumed. See “—Agreement Terms and Pricing.” Area committed is included in area utilized when we commence generating revenue from the customer under the terms of the agreement. For our in-service data centers, we aim to maintain high levels of long-term utilization. As of December 31, 2019, our commitment rate was 91.9% of aggregate net floor area in service, while our utilization rate was 69.0%, in each case excluding joint venture data centers. The difference between commitment rate and utilization rate reflects agreements which were not yet fully implemented with customers still in the process of moving into our data centers. If we secure pre-commitments from customers, particularly largescale capacity commitments from anchor customers, we expect that our utilization rate will continue to lag our commitment rate due to the longer time taken to move in associated with these types of agreements. Our business model provides us with high levels of revenue visibility due to the long-term nature of our customer agreements and substantial backlog. We endeavor to provide high levels of customer service, support, and satisfaction so as to maintain long-term customer relationships and high rates of agreement renewals for our services. Our Data Centers Our data centers are largescale, highly reliable and highly efficient facilities that provide a flexible, modular and secure operating environment in which our customers can house, power and cool the computer systems and networking equipment that support their mission-critical IT infrastructure. We install large power capacity, together with engineering technologies to optimize power usage efficiency, enabling our customers to deploy their IT infrastructure more efficiently and reduce their operating and capital costs. We develop and operate our data centers predominantly in and around Shanghai, Beijing, Shenzhen, Guangzhou, Hong Kong, Chengdu and Chongqing, the primary financial, commercial, industrial and communications hubs in each region of China. We refer to the areas in and around these hubs as Tier 1 markets. Our customers typically use our data centers in Tier 1 markets to house their mission-critical, latency-sensitive data and applications. Our data center locations provide convenient access for our customers and, furthermore, the extensive multi-carrier telecommunications networks in these markets enable our customers to enhance the performance and lower the cost of connectivity to our facilities. We also build-to-suit and operate data centers at lower-tier locations selected by our customers in order to fulfill their broader requirements. 64 In 2019, we commenced construction of 11 new self-developed data centers and the second phase of one existing self- developed data center in Tier 1 markets and one build-to-suit data center in a lower-tier location with a total net floor area of 74,000 sqm. As of December 31, 2019, this capacity was 62.9% committed or pre-committed. In 2019, we completed construction and brought into service nine new self-developed data centers and multiple phases of three existing self-developed data centers in Tier 1 markets with a total net floor area of 65,046 sqm. As of December 31, 2019, this capacity was 79.7% committed and 37.2% utilized. In addition to the above, in 2019, we also commenced construction of three joint venture data centers, with a total net floor area of approximately 11,700 sqm, one of which we completed and brought into service during the year. As of December 31, 2019, all three of the joint venture data centers were 100.0% committed or pre-committed. The following table presents certain information relating to our data center portfolio (excluding joint venture data centers) as of December 31, 2019: (Sqm) Location(2) Greater Shanghai Greater Beijing Greater Bay Area-Mainland Greater Bay Area-Hong Kong region Chengdu Hebei Province-ZB Total Type Self-developed Third party Total Area Area under Area held for in service(1) construction(1) development 70,881 52,888 72,263 963 14,512 14,456 23,074 47,699 7,000 7,061 0 5,000 76,742 83,664 55,442 7,440 21,506 0 225,963 89,834 244,794 216,079 9,884 89,834 0 244,794 0 225,963 89,834 244,794 (1) Excludes approximately 3,900 sqm net floor area relating to joint venture data centers in service, 100% of which was committed and approximately 7,800 sqm net floor area relating to joint venture data centers under construction, 100% of which was pre-committed as of December 31, 2019. (2) Greater Shanghai includes the area in and around Shanghai such as Kunshan and Changshu. Greater Beijing includes the area in and around Beijing such as Langfang. Greater Bay Area-Mainland includes Guangzhou, Shenzhen and Huizhou. Greater Bay Area-Hong Kong region includes Hong Kong and Macau. As of December 31, 2019, our total area committed (excluding joint venture data centers) was 264,878 sqm, of which 207,716 sqm and 57,162 sqm related to data centers in service and data centers under construction, respectively. Self-Developed Data Centers As of December 31, 2019, we operated thirty-five self-developed data centers with an aggregate net floor area of 216,079 sqm in service. As of the same date, we had a further fourteen new self-developed data centers with an aggregate net floor area of 89,834 sqm, under construction. In addition, we had an estimated aggregate developable net floor area of approximately 244,794 sqm held for potential future development in Tier 1 markets. In addition, subsequent to the 2019 year-end, we have secured a further estimated aggregate developable net floor area of approximately 106,156 sqm area held for potential future development in Tier 1 markets. High-Performance Features. Our self-developed data centers generally feature: High Availability. Over 90% of our self-developed data center capacity in service and under construction is equipped with 2N redundant delivery paths for power, cooling and other critical systems. 2N redundancy entails significant additional up-front investment and decreases the yield of net floor area in a building of a given size. By installing 2N redundancy and operating our facilities to the highest standards, we are able to satisfy the requirements of the most demanding customers for housing their mission-critical IT infrastructure. 65 High Power Density. Our self-developed data center capacity in service and under construction has an average power density of approximately 2.2 kW/m2, which we believe is far above the average for data centers in China. High power density must be incorporated into the data center design from inception and entails increased development cost per sqm of net floor area. By installing high power density, we enable our customers to deploy their IT infrastructure more efficiently and to optimize their IT infrastructure performance. This is of particular importance to hyperscale cloud service provider and large internet customers as it reduces their IT investment and operating costs. High Power Efficiency. Our self-developed data centers are designed to achieve high power efficiency, which is expressed conversely by a low Power Usage Effectiveness, or PUE, ratio. Our self-developed data centers had around 1.25-1.4 times PUE on average in stabilized operation, which we believe is significantly below the average for data centers in China. High power efficiency reduces operating costs, for the benefit of our customers and ourselves, and reduces our carbon footprint. A low PUE ratio is of particular importance to hyperscale cloud service provider and large internet customers who have the most demanding performance targets. In addition to the high-performance features described above, our data centers provide flexible fit-out, sufficient floor load bearing strength and clear slab-to-slab height to support dense deployment of IT hardware, multiple layers of physical security, early fire detection monitoring and fire suppression systems, diverse connectivity, and other amenities. This combination of high availability, high power density, high power efficiency and other features enables us to serve the most sophisticated and demanding users of data center services who seek cost efficient solutions for their requirements, without compromise on performance across multiple operating parameters. Types of Data Centers. We have a diversified and flexible approach to developing our data center portfolio. We categorize our self-developed data centers into the following three types: Purpose-Built. Purpose-built data centers are facilities which are designed and constructed specifically for use as data centers. Our purpose-built facilities comprise those that we design ourselves and for which we directly oversee the construction and fit out, as well as certain of the facilities that we lease or have acquired from third parties. Purpose-built and build-to-suit facilities represent approximately 42.6% by aggregate net floor area of our self-developed data centers in service and under construction as of December 31, 2019. Converted. Conversion involves repurposing existing industrial buildings for use as data centers. We undertake conversions in order to fulfill demand where time-to-market and site opportunity do not allow us to purpose-build. We carefully select such buildings based on their suitability for use as data centers. We design and construct to the same high technical specifications as our purpose-built data centers, so as to ensure that the end product is of a comparable standard. Converted facilities represent approximately 57.4% by aggregate net floor area of our self-developed data centers in service and under construction as of December 31, 2019. Build-To-Suit. Build-to-suit data centers are facilities which are located in lower-tier markets to fulfil the broader requirements of our strategic customers. We develop and operate build-to-suit projects independently, as well as through the joint ventures which we are establishing with GIC. The projects are typically greenfield developments on the customer’s own campus. Data Center Tenure. We hold our self-developed data center buildings either through direct ownership or lease. In China, land cannot be owned outright, but is secured through land use rights. For data center buildings which we own, we have the right to use the underlying land for up to 50 years, which is the longest permissible period, except for our Guangzhou Land where the period of the land use right is 20 years, plus ownership of the buildings and other fixed assets comprising the data center. In Hong Kong, almost all the land is leasehold land leased from the Hong Kong government. The tenure of the relevant government leases for the two parcels of brownfield land where our HK 1 and HK 2 are located that were purchased by GDS in 2018 and 2019 respectively will expire in June 2047 and the residue of the term of years of the relevant Government Leases is approximately 27 years. For data centers that we lease, we enter into long-term leases with the owners of the building generally for periods of fifteen to twenty years, which is the longest permitted lease period under PRC law. However, in the case of the build-to-suit projects which we have undertaken to date, where the owner of the building shell is our customer, the lease term is usually ten years. 66 Stage of Development. We categorize our data centers, and the corresponding net floor area, according to the following stages of development: In Service. Data centers are categorized as in service once the construction of the building is complete, critical systems have been installed, the facility has passed rigorous integrated system testing, government approvals for operation are obtained, and one or more computer rooms have been fully equipped and fitted out ready for utilization by customers. Once this stage has been reached, we categorize the entire net floor area of the data center (or phase of a data center) as area in service, including the net floor area of computer rooms, if any, which may require additional capex for equipping and fitting out prior to utilization by customers. Under Construction. Data centers are categorized as under construction once we have secured control of the site, obtained the necessary construction and other permits, established the design, and building and engineering works are in progress. We also categorize data centers as under construction when the shell and core are being developed by the building landlord under certain circumstances. We usually construct our data centers in a single phase. However, in some cases, we construct data centers in several distinct phases for reasons such as optimal design, sales plan, and timing of activation of power supply. When we successfully secure pre-commitments from customers, we calculate pre- commitment rate based on the area under construction. Held for Future Development. Area held for future development consist of the estimated data center net floor area that we have secured for potential future development by different means, including greenfield and brownfield land which we have acquired or which we expect to acquire pursuant to binding framework agreements with local governments, building shells which we have purpose-built on land which we own, and existing buildings which we have acquired or leased with the intention of converting or redeveloping into data centers, but which are not actively under construction. The developable net floor area estimates are subject to a number of contingencies and uncertainties.

Our self-developed area under construction had an average power density of approximately 2.5 kW/m2. Self-Developed Data Center Capacity Held for Future Development. We have also secured data center capacity that we classify as held for future development. We have acquired land and entered into binding framework agreements with local governments for further land acquisitions, and we have acquired and leased buildings which could potentially be developed into data centers with an estimated aggregate developable net floor area of approximately 244,794 sqm in Tier 1 markets. 68 Self-developed data center capacity held for future development in Tier 1 markets include: (i) SH14, an existing building in Shanghai, which we have acquired; (ii) Changshu Land Phase 1, a site in Changshu for which we have acquired the land; (iii) Changshu Land Remaining Phases, for which we have signed a binding framework agreement with local government, under which the government commits to initiate the sales process for acquiring the land use right and provide assistance to us in obtaining necessary government approvals and resources for the construction and operation of the project and to allocate power capacity, and we commit to invest in developing the land for data center use and to generate taxable income. The land is reserved subject to the completion of land expropriation and relocation, satisfaction of other grant conditions and subsequently entering into a land use right grant contract through relevant tender, auction or listing-for-sale procedures; (iv) LF4 and LF5, two data centers we intend to develop on the second phase of Langfang Land Site 1, for which we have acquired the land use right; (v) Langfang Land Site 1 Phase 3, for which we have signed a binding framework agreement with local government, under which the government commits to initiate the tender, auction or listing-for-sale process for the acquisition of the land use right and provide assistance to us in obtaining necessary government approvals and resources (including water supply, power supply, heating supply, among others) for the construction and operation of the project, and we commit to invest in developing the land for data center use and to generate taxable income. The major commitments of the government and us are subject to the completion of land expropriation and relocation, satisfaction of other grant conditions and subsequently entering into a land use right grant contract through relevant tender, auction or listing-for-sale procedures; (vi) Langfang Land Site 2, adjacent to our Langfang Land Site 1, for which we have acquired land use rights; (vii) SZ4 (Phase 2), an existing building in Shenzhen which we have leased and which we are developing in two phases; (viii) a site in Guangzhou for which we have acquired land use rights; (ix) GZ3 (Phase 3), extension of an existing building in Guangzhou which we have leased and are developing in three phases; (x) HZ1, an existing building in Huizhou, Guangdong Province, China, which we have leased; (xi) HK2, a brownfield site in Hong Kong nearby HK1, which we have acquired and intend to redevelop; (xii) CD2 (Phase 2), extension of an existing building shell in Chengdu which we own and are developing in two phases; and (xiii) CD3, a site in Chengdu adjacent to CD1 and CD2 for which we have secured land use rights.

The categorization of data centers by stage of development is applied to each phase of the SZ4, GZ3 and CD2 project. 69 As of December 31, 2019, 91.3% of our Tier-1 market self-developed area held for future development was related to property which we own or expect to own pursuant to binding framework agreements and 8.7% was related to property which we lease. The following table presents certain information relating to our self-developed data centers that have a further aggregate developable net floor area of approximately 106,156 sqm area held for future development in Tier 1 markets subsequent to December 31, 2019: Market Greater Shanghai Chongqing Data center Tenure Owned SH16 and SH17 Shanghai Pujiang Site Remaining Phases Owned Owned Chongqing Land Development 22,656 50,500 33,000 Area Held For Future Between August 2019 and March 2020, we have entered into several framework agreements or equivalent legal documents with relevant local governments and development agencies with a view to potentially acquiring the land use rights for certain parcels of land for the development of data centers in (i) Wulanchabu, located approximately 300 kilometers from Beijing, and (ii) Nantong, located approximately 100 kilometers from Shanghai. The acquisition of such land use rights is subject to execution of definitive agreements. We expect that the consummation of these acquisitions would provide us with additional developable net floor area of approximately 34,000 sqm in lower-tier locations. The developable net floor area estimates are subject to a number of contingencies and uncertainties. Third-Party Data Centers In addition to operating and providing services in our self-developed data centers, we also provide data center services with respect to net floor area that we lease from third-party data center providers on a wholesale basis and use to provide colocation and managed services to our customers. For this kind of facility, we typically enter into leases for fixed terms of three to ten years. As of December 31, 2019, we operated capacity at approximately 20 third-party data centers with an aggregate net floor area of 9,884 sqm in service. The third-party data centers where we lease capacity on a wholesale basis were not purpose-built or converted according to our design and technical specification. However, on a selective basis, we may carry out improvement work at third-party data centers in order to attain the performance levels required to serve our customers. In particular, one of our third-party data centers is a facility in which we leased increasing amounts of space over time, so that we now lease the entire data center. As we accumulated leased data center capacity in the data center over time, and we never conducted any comprehensive conversion or repurposing of the facility, we continue to categorize that data center as a third-party data center. Joint Venture Data Centers In August 2019, we entered into a strategic cooperation framework agreement with GIC to develop and operate ten hyperscale build-to-suit data centers at lower-tier locations in China for a leading internet and cloud service provider, which is a strategic customer of us. In parallel with the strategic cooperation framework agreement, we also signed a memorandum of understanding with the same strategic customer to develop seven build-to-suit data centers at several of its campuses serving different regions of China, including Nantong, Jiangsu Province, Heyuan, Guangdong Province and Wulanchabu, Inner Mongolia Autonomous Region. According to the strategic cooperation framework agreement, we will set up individual project companies to undertake the development of each data center and own 100% during the construction phase. Upon completion of each data center, we will sell a 90% equity interest in the project company to GIC and accordingly the project company will become a joint venture. We will continue to hold the remaining 10% equity interest of the project company and provide management and operating services to the joint venture, and GIC will pay us management fees for our provision of management services. As of December 31, 2019, we had approximately 3,900 sqm net floor area relating to one joint venture data center in service, 100% of which was committed, and approximately 7,800 sqm net floor area relating to two joint venture data centers under construction, 100% of which was pre-committed. We still held 100% of the equity interests in the project companies holding such joint venture data centers as of December 31, 2019, as certain equity transfer conditions had not been met. 70 Lease Agreements Relating to Our Data Centers We enter into leases in connection with our self-developed data centers. In addition, certain third-party data centers in which we lease capacity on a wholesale basis are subject to property lease agreements. Under relevant PRC laws and regulations, lease agreements are required to be registered or filed with the relevant housing authorities. Among the data centers that we lease, including those under construction, the majority of the lease agreements have not been filed with relevant authorities in accordance with the applicable PRC laws and regulations. The failure to register or file the lease will not affect the legal validity of the lease agreements but may subject us to fines. In order to address the situations where the relevant leases have not been registered by the lessors, we have communicated with the relevant lessors with regard to completing the registration of the relevant lease agreements to the extent practicable. However, there is no guarantee that the lessors will respond to our requests or take remedial action with regard to the lack of registration and filing, and we, or the third-party lessors, may be liable if timely rectifications are not made. A portion of any such losses will be recoverable from the lessors according to the terms of certain of the lease agreements. See “Item 3. Key Information— D. Risk Factors—Risk Factors Relating to Our Business and Industry—Our failure to comply with regulations applicable to our leased data centers may materially and adversely affect our ability to use such data centers.” Our Services We offer a broad range of services including colocation services and managed services, which includes managed hosting services and managed cloud services. We also provide certain other services, including consulting services. Colocation Services We offer our customers a highly secure, reliable and fault-tolerant environment in which to house their servers and related IT equipment. Our core colocation services primarily comprise the provision of critical facilities space, customer-available power, racks and cooling. Our customers have several choices for hosting their servers, networking and storage equipment. They can place their equipment in a shared or private space that can be customized to their requirements. We offer a variety of power options to suit individual customer requirements, including high power density racks. In some instances, colocation customers will request that we provide IT equipment for their use in our data centers. In such cases, we will sell such IT equipment to the colocation customer. Managed Services Managed Hosting Services. Our managed hosting services comprise a broad range of value-added services, covering each layer of the data center IT value chain. Our suite of managed hosting services includes business continuity and disaster recovery, or BCDR, solutions, network management services, data storage services, system security services, operating system services, database services and server middleware services. Our managed hosting services are tailored to meet the specific objectives of individual customers. We help our customers reduce their costs, re-engineer existing processes, improve the quality of service delivery and realize a better return on their investment. Our network management services help our customers to design and maintain their private network systems. Our data storage services provide storage architecture design and customization for specific requirements. Our system security services include identity and access control, firewall management, intrusion protection and vulnerability protection services. Our operating system services provide pro-active administration, management, monitoring and reporting across a wide range of operating systems. Our database services provide database customization and performance tuning operation, administration and monitoring services across a range of database platforms. Our server middleware services provide customization and performance tuning services across a range of platforms. We also offer consulting services for customers who request additional know-how and guidance relating to disaster recovery and other aspects of our managed hosting services. Our managed hosting services are provided on a continuous basis over the term of the agreement. Managed Cloud Services. The adoption of cloud computing continues to rise and has become a key element of IT strategy for enterprises globally. We believe that our data centers are well-suited for the hosting of cloud platforms. As a result, we have succeeded in attracting most of the largest cloud service providers in China to colocate their public cloud platforms in our data centers. 71 The presence of major public cloud platforms in our data centers enables us to offer our enterprise customers direct private connection to high capacity cloud resources of their choosing across our network infrastructure with a number of operational benefits, such as high reliability, high flexibility, and high efficiency. We also assist our enterprise customers to access cloud resources by providing and reselling public cloud services offered by major cloud service providers, including certain of our major customers. This has the added benefit of assisting our cloud service provider customers with their route to market. Large enterprises are increasingly deploying a combination of multiple private, hosted, or public cloud services, a configuration known as hybrid cloud. While this configuration can provide enterprises with greater flexibility, scalability, security and cost efficiency, it also presents new challenges in integrating and operating multiple systems. Leveraging our long track record as a provider of IT managed services, we are developing an innovative service platform to assist our enterprise customers to integrate and control every aspect of their hybrid cloud computing environment across their private servers and one or more public cloud service providers. In addition, we offer consulting services for customers who request additional know-how and assistance concerning the implementation of cloud-based solutions, such as migration from physical to cloud-based hosting. As part of the offering, we also provide our customers with cloud resources. Data Center Sourcing and Development We believe that the size, location, and quality of our facilities are key to maintaining our competitiveness. We apply the same rigor to the process of sourcing, design and construction as we do to our operations. We have a substantial in-house team dedicated to sourcing, feasibility analysis, technical design, costing and project management. The process is comprised of the following steps: Planning and Sourcing. Our strong customer and industry relationships, combined with our data center presence in key markets in each region and direct sales force, afford us insight into the size, timing, and location of future demand. We incorporate this insight into a multi-year resource plan for each of the key markets. Our in-house team begins sourcing potential sites up to three or more years in advance of planned delivery. We seek to secure sites both in close proximity to central business districts or to areas where there is a concentration of enterprise operations centers so as to satisfy the location preferences of our target customer segments. We consider both greenfield sites when available, and also existing industrial buildings suitable for conversion. We require security of tenure for a minimum of ten years. Our team works closely with local government authorities to obtain necessary permits and approvals, with electric utilities to obtain sufficient power infrastructure and supply, and with telecommunications carriers to ensure multi-carrier connectivity to our data centers. We generally seek to secure sites that can support a net floor area of at least 5,000 sqm per data center building and sufficient power capacity to fulfill the requirements of the customer segments which we expect to serve in the facility. Design and Construction. We undertake the technical design, specification and costing in-house as we believe that these are important to ensuring the data center meets our strategic requirements. This also enables us to achieve a high level of design standardization. We continuously study new engineering and technologies to maintain an advanced design. Our in-house team also takes responsibility for construction project management, which includes scheduling, vendor selection, procurement, budget control and cost analysis, and quality supervision and assurance. We believe that these elements are important to ensuring the project is completed on time, within budget and to the required quality standard. Commissioning and Fit Out. After the shell and core of a building are completed, we work with our contractors and suppliers to make the data center ready for service, or RFS. This involves: (i) obtaining necessary operating permits and approvals; (ii) equipping and fitting out the critical facilities area for utilization by customers; and, (iii) pre-operational testing, also referred to as commissioning, to ensure that the facility is fully functioning and capable of providing the required service levels. We have a team dedicated to testing and commissioning before operations commence. Operations We have separate teams for data center operations and service delivery. Our data center operations team is responsible for directing, coordinating and monitoring the daily operation of our data center facilities. Our service delivery team is responsible for delivery of the services which we provide to customers on a 24/7 basis. Our teams are deployed in regional operations centers, as well as on site, in order to provide two layers of management and support. We outsource part of the above operations and service delivery, primarily on-site security, cleaning and greening service, part of the 24/7 on duty operations and IT and customer service delivery to reputable third-party service providers. 72 We undertake in-house all technical functions which impact data center performance, including floor planning, equipment lifecycle management, optimizing data center efficiency, surveillance of the critical facilities environment and network performance, incident response management and rectification. We also undertake in-house substantially all activities which have a direct bearing on customers, including support for set up of customer IT equipment, remote hands services, outsourced IT operations, incident and compliance reporting, and response to customer requests. We have developed a proprietary Data Center Operation Management Platform which provides real-time information on many aspects of data center operating performance and enables us to streamline our data center management processes. We have also developed robust operating procedures, protocols and standards which enable us to meet or exceed the performance and quality levels specified in our service level agreements, or SLAs, with the most sophisticated customers. We have been certified ISO9001, ISO20000 and ISO27001 for almost ten years, and received certification for ISO 22301 in September 2016. By the end of 2019, we had 12 data centers awarded with “Management and Operations (“M&O”) Approved Site” awards by the Uptime Institute, an unbiased advisory organization focused on improving the performance, efficiency, and reliability of business-critical infrastructure. In 2019, we signed a three-year framework contract with the Uptime Institute to support continuous verification of operation and maintenance capabilities of our data centers. At the same time, in order to verify the unified regional operation and management capability based on our Data Center Operation Management Platform, the Uptime Institute also awarded the regional “M&O Approved Site” to GDS. By the end of 2019, the four GDS regions covering China have each been awarded the Uptime region-level “M&O Approved Site.” We will continue to apply for this award in 2020. We believe that our standard of data center operations, which reflects our history and culture as an IT service provider, set us apart from many data center service providers in China. Our Customers We consider our customers to be the end users of our data center services. We may enter into agreements directly with our end user customers or through intermediate contracting parties. We have long-standing relationships with all the major PRC telecommunications carriers who are both partners providing network services to our customers as well as intermediate contracting parties for the sale of colocation services to our customers. Because we negotiate with, maintain and support each of the end users of our services, even where the actual data center agreement is made with the telecommunications carrier, we consider the end user to be our end customer. The end user customer generally has separate decision-making authority and a services procurement budget that is distinct from that of the telecommunications carriers with whom we contract. We currently serve 624 customers, including hyperscale cloud service providers and large internet companies, a diverse community of PRC and foreign financial institutions as well as telecommunications carriers and IT service providers and large domestic private sector and multinational corporations, many of which are leaders in their respective industry verticals. We host the largest PRC and global public cloud platforms operating in China, some of which are present in multiple GDS data centers. Our cloud service provider, large internet and financial institution end user customers accounted for 72.6%, 14.3% and 6.9% of our total area committed (excluding joint venture data centers) as of December 31, 2019, respectively. Our three largest end user customers accounted for 30.6%, 21.1% and 10.4%, respectively, of our total area committed (excluding joint venture data centers) as of December 31, 2019. No other end user customer accounted for 10% or more of our total area committed as of that date. The following table presents the total area committed (excluding joint venture data centers) of our top five end user customers, all of which are cloud service providers or large internet companies, as of December 31, 2019: End User Customer Customer 1 Customer 2 Customer 3 Customer 4 Customer 5 Total area committed (sqm) (1)(2) Total area committed (%)(2) 81,113 55,767 27,575 19,186 8,219 30.6 % 21.1 % 10.4 % 7.2 % 3.1 % Includes data center area for which we have entered into non-binding agreements or letters of intent, or have received other confirmations from, certain customers. (1) (2) Excludes joint venture data centers. 73 We endeavor to establish strategic relationships with key customers, particularly hyperscale cloud service providers and large internet companies who have large data center capacity requirements and who can help enhance the value of our data center ecosystem. Agreement Terms and Pricing Agreements with our cloud service provider and large internet customers typically have an unbundled pricing structure, whereas agreements with our financial institution and large enterprise customers typically have a bundled pricing structure. In the case of agreements with unbundled pricing, we bill our customers for services based on a fixed charge for the amount of net floor area and/or power capacity which is committed to them for their use in the customer agreements. During the period when customers are moving into our data centers, we bill our customers based on the higher of the net floor area and/or power capacity which they are actually using and the minimum utilization commitments in the customer agreements. From the end of the move in period, which is typically after 12 to 24 months, until the end of the agreement, we bill our customers based on the full net floor area and/or power capacity committed to them in the customer agreements. In addition to commitment-based charges, we also bill our customers for services based on the actual amount of power which they consume that varies from billing period to period. In the case of agreements with bundled pricing, we bill our customers for services based on a fixed charge, often expressed as a price per rack or cabinet, for the amount of net floor area and power capacity which is committed to them and billable according to the terms of the customer agreements, without any additional charge for power consumed. Pricing is generally flat over the contract term, except for the price for power consumed which may be subject to adjustments when input power tariffs change. A substantial majority of our customer agreements are multi-year agreements. Agreements for our cloud service provider and large internet customers typically have terms of three to ten years, while agreements with our financial institution and enterprise customers are for between one to five years. Our typical service agreement provides a notice period of one to six months for early termination, and in certain cases, we are entitled to a substantial amount of early termination damages equivalent to up to 12 months’ service fee, in addition to payment for our services already provided before such early termination. Sales and Marketing Sales. Our sales activities are mainly conducted through our direct sales force. We organize our direct sales force into four geographic regions, Northern China, Southern China, Eastern China and Western China. We incentivize our sales force to meet their annual targets through performance-based bonuses. For new customers, our sales cycle typically begins with creating a sales plan for a particular region or industry and then identifying new customers in these regions or industries. We also receive referrals from our vendors and other relationships, and often our reputation attracts customers to our services without any directed sales efforts. For our existing customers, our sales team focuses on identifying upsell opportunities. Many of our customer agreements are won through a competitive bidding process. For new customers, the bidding process begins with evaluation of the potential customer’s requirements. We formulate a service proposal based on these requirements. Our team representing multiple departments prepares a proposal to meet the required service scope and level. We negotiate the agreement and service details. Marketing. To support our sales effort and to actively promote our brand, we conduct wide-ranging marketing programs. Our marketing strategies include active public relations and ongoing customer communications programs. We participate in a variety of IT industry and financial services industry conferences and workshops to raise awareness about the value of data center services. We also build our brand recognition by participating in industry and government workshops and industry standard-setting bodies, such as the China National Institute of Standardization Committee on Disaster Recovery for Information Systems. 74 Technology and Intellectual Property We rely on a combination of copyright, trademark, trade secrets and other intellectual property laws, nondisclosure agreements and other measures to protect our intellectual property, such as our proprietary storage and management system, for which we have registered a copyright. We also promote protection through contractual prohibitions, such as requiring our employees to enter into confidentiality and non-compete agreements which are applicable to selected employees. We derive most our revenues in China , our figure trademark, in a majority of our services. We have registered the figure trademark in China in several categories and use that cover our service areas and we plan to register the figure trademark in China in certain additional categories. We have also registered the pure text of “GDS” as a trademark in several categories that cover our services areas, however, a third party has also registered the pure text of “GDS” as a trademark in certain IT-related services. It is our belief, based on our industrial experience, that our business is different from the services for which the third party registered its trademark. Nevertheless, since the services for which the third party’s trademark is registered are also IT-related and could be deemed as similar to ours to some extent, we cannot assure you that a government authority or court will hold the same view with us that such similarity will not cause confusion in the market. In such a case, if we are to use the pure text of GDS as our trademark, we may be required to explore the possibility of acquiring this trademark, or entering into an exclusive licensing agreement with the third party, which will cause us to incur additional cost. See “Item 3. Key Information—D. Risk Factors—Risk Factors Relating to Our Business and Industry—We may be subject to third-party claims of intellectual property infringement.” Environmental and Operational Sustainability Initiatives As a leading developer and operator of high-performance data centers in China, we are dedicated to delivering cutting-edge, comprehensive data center solutions that offer high power efficiency, guaranteed uptime, a key market footprint, carrier neutrality, and rigorous operating standards. We are equally committed to delivering these solutions in a responsible, transparent manner that drives sustainability and enhances value creation for all our stakeholders. Environmental sustainability. Managing our data centers’ energy consumption and corresponding environmental impact is of great importance to us. We use energy conservation technology in our data centers, including recycling excess heat from the heating and ventilation system, and supply to our office area in the data centers or nearby offices. We also use high-efficiency transformers, modular high-efficiency uninterruptible power supplies, and high voltage direct current to reduce energy transmission and distribution loss. Moreover, we developed a customized energy efficiency assessment tool to more precisely manage our data centers’ PUE. In 2019, our self-developed data centers achieved an average PUE of 1.25-1.4 times, compared to a global average for data centers of 1.67 times in 2019.1 We are also making progress in reducing our greenhouse gas emissions by utilizing renewable energy whenever it is available at the location of our data centers. We use hydroelectric energy for our two self-developed data centers in Chengdu and wind power for our four build-to-suit data centers at Zhangbei, Hebei Province. Several of the joint venture data centers in our development program will also use renewable energy. As of December 31, 2019, seven of our self-developed data centers have been recognized and awarded sustainability related certifications by leading domestic and global organizations. Among the seven data centers, three have earned LEED certifications with two having been conferred with a gold award, two have been recognized as National Green Data Center by the MIIT and six have been honored as Green Data Center by Open Data Center Committee (ODCC) including one 5A Level data center, which is regarded as the highest standard of green data center in China. In addition, twelve of our facilities have obtained the Uptime Institute’s Management & Operation Stamp of Approval, which is widely recognized as the global standard of excellence for data center reliability, sustainability and efficiency. Information security. GDS is dedicated to offering our customers first class disaster recovery solutions and efficient high- availability hosting, network, and cloud services. We have established an information security management task force to be responsible for identifying, evaluating, and mitigating potential information security risks related to our business operations. We have formulated GDS cyber security management policy and information security management guidelines to provide a framework for the protection of information security and all valuable information, data and intellectual property within GDS. 1 Uptime Institute: 2019 Annual Data Center Survey Results 75 Anti-corruption. We have a zero-tolerance policy for corruption. We operate our business in China and Hong Kong and are thus subject to PRC and Hong Kong laws and regulations related to anti-corruption, which prohibit bribery to government agencies, state or government owned or controlled enterprises or entities, to government officials or officials that work for state or government owned enterprises or entities, as well as bribery to non-government entities or individuals. We are also subject to the FCPA, which generally prohibits companies and any individuals or entities acting on their behalf from offering or making improper payments or providing benefits to foreign officials for the purpose of obtaining or keeping business, along with various other anti-corruption laws. We have compliance policies in place that clearly define the company’s compliance requirements, including business ethics, vendor access and the acceptance and provision of travel and entertainment and gifts. We have also established an ethics committee under the oversight of the audit committee to supervise matters related to FCPA compliance. Our whistle blowing policy and the related reporting mechanism provide a confidential and protected channel for reporting suspected compliance violations. Regardless of position or location, we require all GDS employees to comply with our anti-corruption compliance policies and attend related trainings to embrace the highest standard on integrity. We constantly make improvements to our procurement policies and processes from the compliance perspective, and have implemented measures including conducting supplier due diligence, requiring our suppliers to enter into non-disclosure agreements and make commitments to act with integrity. Employment and talent development. GDS is committed to providing all of its employees with equal employment opportunities and a workplace culture of honesty, integrity, and mutual respect. We regularly update our employee handbook to address our talent recruitment principles and strongly oppose discrimination or harassment based on characteristics including race, religion, gender, age, and nationality. As of December 31, 2019, GDS had 1,087 full-time employees, of which, 20% were female. Female employees comprise 25% of our mid to senior level management staff and 18% of our board of directors are women. We aim to provide our employees with a fair and transparent career development platform, with training opportunities available to all employees. We adopt “growth mindset” and use 3E (Experience, Exposure and Education) as our main development methodology to provide a wide range of orientation for new hires, on-job training, internal and external knowledge sharing, formal professional training, job related certification and others. Competition We offer a broad range of data center services and, as a result, we may compete with a wide range of data center service providers for some or all of the services we offer. We face competition from the state-owned telecommunications carriers, namely China Telecom, China Unicom and China Mobile. One of the main purposes for which these carriers develop data centers is in order to facilitate the sale of related telecommunications network services. In locations outside of the key economic hubs, these three carriers may sometimes be the only available provider of data center services. We distinguish ourselves from these carriers because we are carrier-neutral, enabling our customers to connect within our facilities with all three carriers based on their cost and/or network and application requirements. We compete on the basis of our data center quality, operating track record and differentiated managed service capabilities. Although we compete with carriers for colocation customers, our customers also rely on the connectivity that carriers provide. We believe that we also have a mutually beneficial relationship with these carriers since our data center services often help carriers attract more customers for their telecommunications services. We also compete with other carrier-neutral data center service providers, including: Domestic carrier-neutral data center service providers. We compete with domestic carrier-neutral data center service providers with a presence in some of our markets, such as Sinnet, Dr. Peng, Baosight, AtHub, 21Vianet, Tenglong and ChinData. We believe that we are well positioned in terms of our operational track record and our ability to: deliver high-performance data center services in all key markets; maintain consistently high facility and service quality; continue capacity expansion in all key markets to accommodate growing demand; and provide differentiated managed service offerings with a unique value proposition. 76 International carrier-neutral data center service providers. We compete to a lesser extent with foreign carrier-neutral data center service providers such as Equinix, KDDI and NTT Global Data Centers, each of which has a presence in Shanghai and/or Beijing and primarily serve their international customers. We believe that we distinguish ourselves by our larger capacity and more extensive market presence across the key economics hubs in China, deep operating knowledge and long track record in the China market, and long-term relationships with the telecommunications carriers. Employees and Training We had 740, 893 and approximately 1,100 employees as of December 31, 2017, 2018 and 2019, respectively. The following table sets forth the number of our employees by function as of December 31, 2019: Colocation services Managed services Sales and marketing Management, finance and administration Total Number of Employees % of Total 605 97 81 317 1,100 55.0 % 8.8 % 7.4 % 28.8 % 100.0 % To maintain the highest level of service, employee training and certification is essential to ensure that our employees meet and exceed industry requirements. Many of our engineering employees have received training and certifications from globally- recognized IT service organizations, such as IBM AS/400 certifications, CCIE Safety Certified qualifications, Vmware VCP and CISP Certificates. We pay most of our employees a base salary and performance-based bonuses and provide welfare and other benefits required by law. In addition, we provide some of our employees with share-based compensation to align their interests more closely with our shareholders. We believe that our compensation and benefits packages are competitive within our industry. We have not had any labor disputes that materially interfered with our operations and we believe that our employee relations are good. We also outsource certain operations, primarily on-site security, cleaning and greening service, part of the 24/7 on duty operations and IT and customer service delivery to reputable third-party service providers. Facilities Our headquarters are located at F4/F5, Building C, Sunland International, No. 999 Zhouhai Road, Pudong, Shanghai 200137, People’s Republic of China. We have additional offices in Beijing, Suzhou, Shenzhen, Guangzhou, Hong Kong and Chengdu. Our offices are located on leased premises totaling approximately 8,700 sqm across China. We lease our office premises from third parties. Insurance We have in place insurance coverage up to a level which we consider to be reasonable and which covers the type of risks usually insured by companies on the same or similar types of business as ours in China. Our insurance broadly falls under the following eight categories: construction and installation, work interruption expense due to public health event, business interruption for lost profits, property and casualty, public liability, directors and officers liability, employer liability and commercial employee insurance. Legal Proceedings We may become subject to legal proceedings, investigations and claims incidental to the conduct of our business from time to time. 77 On August 2, 2018, a securities class action lawsuit was filed against GDS Holdings Limited, our Chief Executive Officer Mr. William Wei Huang, and our Chief Financial Officer Mr. Daniel Newman (collectively, “Defendants”) by Hamza Ramzan, a GDS shareholder in the United States District Court for the Eastern District of Texas. The complaint purports to assert claims on behalf of a class comprising purchasers of GDS’s ADS shares during the proposed class period from March 29, 2018 to July 31, 2018. On October 26, 2018 the Court appointed GDS shareholder Yuanli He as the lead plaintiff in the lawsuit, and on December 24, 2018 plaintiffs filed a consolidated amended complaint. The amended complaint alleged, among other things, that GDS made material misstatements and omissions in its 2017 Form 20-F Annual Report with respect to the commitment rate and utilization rate at GDS’s GZ1 data center, and inflated the purchase prices for its acquisitions of the GZ2, GZ3, and SZ5 data centers. The complaint alleged violations of Section 10(b) of the Exchange Act, 15 U.S.C. § 78j(b), and Rule 10b-5 promulgated thereunder by the SEC, against all Defendants and also alleged control person claims under Section 20(a) of the Exchange Act against our Chief Executive Officer Mr. William Wei Huang and our Chief Financial Officer Mr. Daniel Newman. The complaint sought, among other relief, class certification of the lawsuit, unspecified damages, prejudgment and postjudgment interest, costs and expenses. On February 22, 2019, Defendants filed a motion to dismiss the amended complaint in the United States District Court for the Eastern District of Texas and, alternatively, to transfer venue to the United States District Court for the Southern District of New York. On September 30, 2019, the court granted Defendants’ motion to transfer the case to the United States District Court for the Southern District of New York. Defendants then moved to dismiss the action in the United States District Court for the Southern District of New York on December 6, 2019. On April 7, 2020, the court granted Defendants’ motion and dismissed the action in its entirety against all Defendants. The dismissal of the action is not yet final, as Plaintiffs’ time to appeal or seek other relief from the judgment has not yet expired. We believe that Plaintiffs’ claims lack merit and we intend to continue to vigorously defend ourselves in this litigation. Other than as described above, we are not currently a party to, nor are we aware of, any legal proceeding, investigation or claim which, in the opinion of our management, could have a material adverse effect on our business, financial condition or results of operation. Regulatory Matters The following is a summary of the material laws and regulations or requirements that affect our business activities in China or the rights of our shareholders to receive dividends and other distributions from us. Our internet data center businesses are classified as value-added telecommunication businesses by the PRC government. Current PRC laws, rules and regulations restrict foreign ownership in value-added telecommunication services. As a result, we operate our internet data center businesses through our consolidated VIEs, each of which is ultimately owned by PRC citizens and certain of which hold the licenses associated with these businesses. As the development of the internet and telecommunications industry in China is still evolving, new laws and regulations may be adopted from time to time that will require us to obtain additional licenses and permits in addition to those that we currently have, and to address new issues that arise from time to time. As a result, substantial uncertainties exist regarding the interpretation and implementation of current and future Chinese laws and regulations applicable to the data center services industry. See “Item 3. Key Information—D. Risk Factors—Risk Relating to Doing Business in the People’s Republic of China.” Regulation on Foreign Investment Restrictions Investment activities in the PRC by foreign investors are principally governed by the Industry Catalog Relating to Foreign Investment, or the Catalog, which was promulgated and is amended from time to time by the MOFCOM and the National Development and Reform Commission, or the NDRC. The Catalog divides industries into three categories: encouraged, restricted and prohibited. Industries not listed in the Catalog are generally deemed as constituting a fourth “permitted” category and open to foreign investment unless specifically restricted by other PRC regulations. Industries such as value-added telecommunication services, including internet data center services, are restricted to foreign investment. On June 30, 2019, the MOFCOM and the NDRC promulgated the Special Management Measures (Negative List) for the Access of Foreign Investment, or the Negative List, which took effective from July 30, 2019. The Negative List expands the scope of industries in which foreign investment is permitted by reducing the number of industries that fall within the Negative List. Foreign investment in value-added telecommunications services (other than e-commerce, domestic multi-party communications, store-and- forward and call center), including internet data center services, still falls within the Negative List. 78 According to the Administrative Regulations on Foreign-Invested Telecommunications Enterprises issued by the PRC State Council on December 11, 2001 and amended on September 10, 2008 and February 6, 2016 respectively, foreign-invested value-added telecommunications enterprises must be in the form of a Sino-foreign equity joint venture. The regulations restrict the ultimate capital contribution percentage held by foreign investor(s) in a foreign-invested value-added telecommunications enterprise to 50% or less and require the primary foreign investor in a foreign invested value-added telecommunications enterprise to have a good track record and operational experience in the VATS industry. On July 13, 2006, the MIIT issued the Circular of the Ministry of Information Industry on Strengthening the Administration of Foreign Investment in Value-added Telecommunications Business, or the MIIT Circular, according to which, a foreign investor in the telecommunications service industry of China must establish a foreign invested enterprise and apply for a telecommunications businesses operation license. The MIIT Circular further requires that: (i) PRC domestic telecommunications business enterprises must not, through any form, lease, transfer or sell a telecommunications businesses operation license to a foreign investor, or provide resources, offices and working places, facilities or other assistance to support the illegal telecommunications services operations of a foreign investor; (ii) value-added telecommunications business enterprises or their shareholders must directly own the domain names and trademarks used by such enterprises in their daily operations; (iii) each value-added telecommunications business enterprise must have the necessary facilities for its approved business operations and to maintain such facilities in the regions covered by its license; and (iv) all VATS providers are required to maintain network and internet security in accordance with the standards set forth in relevant PRC regulations. If a license holder fails to comply with the requirements in the MIIT Circular and cure such noncompliance, the MIIT or its local counterparts have the discretion to take measures against such license holder, including revoking its value-added telecommunications business operation license. In light of the above restrictions and requirements, we conduct our value-added telecommunications businesses through our consolidated VIEs. Regulations Related to Value-Added Telecommunications Business Among all of the applicable laws and regulations, the Telecommunications Regulations of the People’s Republic of China, or the Telecom Regulations, promulgated by the PRC State Council on September 25, 2000 and amended on July 29, 2014 and February 6, 2016 respectively, is the primary governing law, and sets out the general framework for the provision of telecommunications services by domestic PRC companies. Under the Telecom Regulations, telecommunications service providers are required to procure operating licenses prior to their commencement of operations. The Telecom Regulations distinguish basic telecommunications services from VATS. The Telecom Catalogue, was issued as an attachment to the Telecom Regulations to categorize telecommunications services as either basic or value-added. The Telecom Catalogue amended on December 28, 2015 (which took effect from March 1, 2016 and was amended on June 6, 2019), or the 2015 Telecom Catalogue, categorizes internet data centers, online data and transaction processing, on-demand voice and image communications, domestic internet virtual private networks, message storage and forwarding (including voice mailbox, e-mail and online fax services), call centers, internet access and online information and data search, among others, as VATS. The “internet data center” business is defined under the 2015 Telecom Catalogue as a business that (i) uses relevant infrastructure facilities in order to render outsourcing services for housing, maintenance, system configuration and management services for clients’ internet or other network related equipment such as servers, (ii) provides the leasing of equipment, such as database systems or servers, and the storage space housing the equipment and (iii) provides lease agency services of connectivity lines and bandwidth of infrastructure facilities and other application services. Also, internet resources collaboration services business is incorporated into the definition of internet data center business under the 2015 Telecom Catalogue, and defined as “the data storage, internet application development environment, internet application deployment and running management and other services provided for users through internet or other networks in the manners of access at any time and on demand, expansion at any time and coordination and sharing, by using the equipment and resources built on database centers”. Under the 2015 Telecom Catalogue, “fixed network domestic data transmission services” is categorized as a basic telecommunications business and is defined as “a domestic end-to-end data transfer business by wired mode under fixed-net, except for the internet data transfer business”, and the “domestic internet virtual private networks service” is categorized as a value-added telecommunications business and is defined as “a customization business of internet closed user group network for domestic users by self-owned or leased internet network resources of the operators and adopting TCP/IP agreement.” 79 On March 1, 2009, the MIIT promulgated the Administrative Measures for Telecommunications Business Operating License, or the original Telecom License Measures, which took effect on April 10, 2009. The original Telecom License Measures set forth the types of licenses required to provide telecommunications services in China and the procedures and requirements for obtaining such licenses. With respect to licenses for value-added telecommunications businesses, the original Telecom License Measures distinguish between licenses for business conducted in a single province, which are issued by the provincial-level counterparts of the MIIT and licenses for cross-regional businesses, which are issued by the MIIT. The licenses for foreign invested telecommunications business operators need to be applied with MIIT. An approved telecommunications services operator must conduct its business in accordance with the specifications stated on its telecommunications business operating license. Pursuant to the original Telecom License Measures, cross-regional VATS licenses shall be approved and issued by the MIIT with five-year terms. On July 3, 2017, the MIIT issued the Telecom License Measures, which took effect on September 1, 2017 and replaced the original Telecom License Measures. The changes mainly include among others, (i) the establishment of a telecommunications business integrated management online platform; (ii) provisions allowing the holder of a telecommunications business license (including the IDC license) to authorize a company, of which such license holder holds at least 51% of the equity interests indirectly, to engage in the relevant telecommunications business; and (iii) the cancellation of the requirement of an annual inspection of telecommunications business licenses, instead requiring license holders to complete an annual report. On December 1, 2012, the MIIT issued the Circular of the Ministry of Industry and Information Technology of the People’s Republic of China on Further Standardizing the Market Access-related Work for Businesses Concerning Internet Data Centers and Internet Service Providers which clarifies the application requirements and verification procedures for the licensing of IDC and internet service provider, or ISP, businesses and states that entities intending to engage in the IDC or ISP business could apply for a license since December 1, 2012. On May 6, 2013, the Q&A was published on the website of China Academy of Telecom Research. The Q&A, although not an official law or regulation, is deemed by the market as a guideline in practice which reflected the attitude of MIIT as to the application for VATS licenses, especially as to IDC services. To comply with the above restrictions and requirements, among others, GDS Beijing has obtained a cross-regional value- added telecommunications license which permits it to provide data center services across nine cities in China: Beijing, Chengdu, Shanghai, Shenzhen, Suzhou, Guangzhou, Zhangjiakou, Langfang and Tianjin, GDS Shanghai has obtained a cross-regional value- added telecommunications license which permits it to provide data center services across five cities in China: Beijing, Chengdu, Shanghai, Shenzhen and Suzhou, and GDS Suzhou has obtained a cross-regional value-added telecommunications license which permits it to provide data center services across eight cities in China: Beijing, Chengdu, Shanghai, Shenzhen, Suzhou, Guangzhou, Zhangjiakou, and Tianjin. On January 17, 2017, the MIIT issued the Circular of the Ministry of Industry and Information Technology on Clearing up and Regulating the Internet Access Service Market, or the 2017 MIIT Circular, according to which the MIIT determined to clear up and regulate the internet access service market nationwide from the issuance date of the 2017 MIIT Circular until March 31, 2018. The 2017 MIIT Circular provides, among others, that (i) an enterprise that holds the corresponding telecom business license, including the relevant VATS license, shall not provide, in the name of technical cooperation or other similar ways, qualifications or resources to any unlicensed enterprises for their illegal operation of the telecom business, (ii) if an enterprise with its IDC license obtained prior to the implementation of 2015 Telecom Catalogue issued on March 1, 2016, has actually carried out internet resources collaboration services, it shall make a written commitment to its original license issuing authority before March 31, 2017 to meet the relevant requirements for business licensing and obtain the corresponding telecom business license by the end of 2017, failure of which will result in such enterprise not being able to continue operating the business of internet resources collaboration services as it currently does as of January 1, 2018, and (iii) without the approval of the MIIT, enterprises are not allowed to carry out cross-border business operations by setting up on its own or leasing private network circuits (including virtual private networks, or VPNs) or other information channels. We received approvals from the MIIT to expand the scope of GDS Beijing’s IDC license and enable GDS Suzhou’s IDC license to cover internet resources collaboration services, fixed network domestic data transmission services and domestic internet virtual private networks service which, among other things, enable us to provide connectivity services over our own network to cloud and enterprise customers colocated in all of our data centers. 80 Regulations Related to Information Technology Outsourcing Services Provided to Banking Financial Institutions On June 4, 2010, the CBIRC issued the Guidelines on the Management of Outsourcing Risks of Banking Financial Institutions, or the Guidelines, which requires that the banking financial institutions should manage risks in relation to outsourcing services, and thus, outsourcing services providers should meet the relevant standards and requirements with respect to their technical strength, service capacity, emergency response capacity, familiarity to the banking industry and etc., to pass the due diligence investigations conducted by the banking financial institutions pursuant to the Guidelines, and should also make commitments as to fulfilling reporting, cooperating, or other obligations as may be required by the banking financial institutions under the Guidelines. On February 16, 2013, the CBIRC issued the Circular of the China Banking Regulatory Commission on Printing and Distributing the Guidelines for the Regulation of Information Technology Outsourcing Risks of Banking Financial Institutions, or Circular 5. According to Circular 5, the CBIRC is responsible for supervising banking financial institutions in their access management of information technology outsourcing service providers, organizing relevant banking financial institutions to establish service management records for such service providers, and conducting risk assessment and rating of them. For the outsourcing services providers, including those that are engaged in providing outsourcing services of system operation and maintenance, such as outsourcing of operation and maintenance of data centers, disaster recovery centers, machine room ancillary facilities, and etc., a banking financial institution shall submit a report to the CBIRC or the local CBIRC office 20 business days before entering into an outsourcing contract, and the CBIRC or the local CBIRC office may take measures, such as risk alert, interview or regulatory inquiry, for outsourcing risks of the banking financial institution. Outsourcing service providers may not subcontract material services to others. In certain circumstances, including, among others, where the outsourcing service provider (i) commits a serious violation of applicable PRC laws, regulations or regulatory policies, (ii) steals or divulges sensitive information of banking financial institutions, the circumstance of which is severe, (iii) engages in repeated occurrences of service interruption of important information systems or data destruction, loss or divulgence due to such service provider’s negligence in management, (iv) provides low quality services which causes losses to multiple banking financial institutions, and fails to make rectification after being warned repeatedly, or (v) there is an occurrence of other severe information technology risk incident as determined by the CBIRC, the CBIRC may prohibit the banking financial institutions from engaging the services of such outsourcing service provider for a period of at least two years, and such prohibition period may be extended if such outsourcing service provider has not made rectification within two years. In addition, the CBIRC promulgated the Notice of the General Office of China Banking Regulatory Commission on Strengthening the Management of Risks Involved in the Offsite and Centralized Information Technology Outsourcing of Banking Financial Institutions on July 1, 2014, and the Circular of the General Office of the China Banking Regulatory Commission on Performing Supervision over and Evaluation on Offsite and Centralized Information Technology Outsourcing of Banking Financial Institutions on December 2, 2014. Pursuant to these regulations, in order to further administrate and supervise the offsite and centralized information technology outsourcing provided by the outsourcing services providers to the banking financial institutions, the CBIRC requires the contracts between the outsourcing services providers and the banking financial institutions specify, among other things, that outsourcing services providers should comply with the laws and regulations and other regulatory requirements for banking and accept the supervision and review as conducted by the CBIRC. Outsourcing service providers which are non-banking institutions can voluntarily apply to CBIRC to incorporate their services into the supervision and evaluation scope of CBIRC and such service providers, if they pass the inspection of CBIRC, may have priority in being selected to provide outsourcing services to banking financial institutions. However, failure to comply with these regulatory requirements and other incidents, including, among others, (i) violation of applicable PRC laws, regulations or regulatory policies, (ii) stealing or divulgence of sensitive information of banking financial institutions, (iii) repeated occurrences of service interruption of important information systems or data destruction, loss or divulgence due to the service provider’s negligence in management, (iv) low quality services which cause losses to multiple banking financial institutions, or breaches of undertakings or obligations pertinent to such application to CBIRC, and failure to make rectification after repeated warning, or (v) complaints from three or more banking financial institutions about negligence in management or low service quality, would cause such outsourcing services providers to be disqualified for incorporating their services into the supervision and evaluation scope of CBIRC, and CBIRC will not accept their applications for incorporating their outsourcing services into its supervision and evaluation scope within five years. Banking financial institutions are required to gradually terminate their cooperation with any such disqualified service providers. 81 Regulations Related to Land Use Rights and Construction On June 11, 2003, the Ministry of Land and Resources, or the MLR, promulgated the Regulation on Grant of State-owned Land Use Rights by Agreement, which became effective on August 1, 2003. According to such regulation, the land use rights (excluding land use rights of properties to be used for business purposes, such as commercial, tourism, entertainment and commodity residential properties, which land use rights must be granted by way of tender, auction or listing-for-sale according to relevant laws and regulations) may be granted by way of agreement. The local land bureau and the intended user will negotiate the land fees which shall not be lower than the minimum price approved by the relevant government and enter into the grant contract. Upon signing of the contract for the grant of land use rights, the grantee is required to pay the land fees pursuant to the terms of the contract and the contract is then submitted to the relevant local land bureau for the issue of the land use right certificate. If two or more entities are interested in the land use rights proposed to be granted, such land use rights shall be granted by way of tender, auction or listing-for-sale. Furthermore, according to the Provisions on the Grant of State-owned Construction Land Use Right by Way of Tender, Auction and Listing-for-Sale, which is effective from November 1, 2007, land use rights for properties for commercial use, tourism, entertainment and commodity residential purposes can only be granted through tender, auction and listing-for-sale. According to the Interim Regulations of the People’s Republic of China Concerning the Assignment and Transfer of the Right to the Use of the State-Owned Land in the Urban Areas, which is effective from May 19, 1990, after land use rights relating to a particular area of land have been granted by the State, unless any restriction is imposed, the party to whom such land use rights are granted may transfer (for a term not exceeding the term which has been granted by the State), lease or mortgage such land use rights on the conditions provided by laws and regulations. Upon a transfer of land use rights, all rights and obligations contained in the contract pursuant to which the land use rights were originally granted by the State are assigned from the transferor to the transferee. Upon expiration of the term of grant, the grantee may apply for renewal of the term. Upon approval by the relevant local land bureau, a new contract shall be entered into to renew the grant, and a grant fee shall be paid. According to the Land Registration Regulations promulgated by the State Land Administration Bureau, the predecessor of the MLR, on December 28, 1995 and implemented on February 1, 1996, all land use rights which are duly registered are protected by the law, and the land registration is achieved by the issue of a land use right certificate by the relevant authority to the land user. Under the Administration Law of Urban Real Property of the People’s Republic of China, which was amended by the SCNPC on August 26, 2019, and effective from January 1, 2020, the land must be developed in line with the purposes of the land and the deadline for commencement of construction as stipulated in the grant contract. Where construction does not commence within one year of commencement of construction as stipulated in the grant contract, an idle land fee may be charged at a rate of not more than 20% of the fee for the grant of land use rights. Where construction does not commence within two years, land use rights may be forfeited without compensation, except where the commencement of construction is delayed due to force majeure, an act of the government or relevant government departments, or preliminary work necessary for the commencement of construction. Regulations Related to Filing and Energy Conservation of Fixed-Asset Investment On March 8, 2017, the NDRC promulgated the Measures for the Administration of the Approval and Filing of Enterprises' Investment Projects, which became effective on April 8, 2017. Under such regulation, except those concerning national security or involving the allocation of major productive forces nationwide, strategic resource development or vital public interests, among others, investment projects shall be subject to filing administration. The projects subject to filing administration shall undergo the filing formalities under the territorial principle, except as otherwise provided by the State Council. After a project has completed the filing formalities, if the legal person of the project changes, there is any material change in the construction site, scale or content of the project, or the construction of the project is given up, the construction entity shall inform the project filing authority in a timely manner through the online platform, and modify the relevant information. Provinces in China have formulated the administrative measures for the project filing administration measures within their respective administrative regions, and specified the filing authorities and their power. 82 Under the Measures for the Energy Conservation Examination of Fixed-Asset Investment Projects, which was promulgated by the NDRC on November 27, 2016, and effective from January 1, 2017, for an enterprise investment project, the construction entity shall, before commencing construction, obtain the energy conservation examination opinion issued by the energy conservation examination authority. The construction entity shall not commence the construction of a project which fails to undergo energy conservation examination in accordance with the provisions of these Measures or fails to pass energy conservation examination, and if the project has been completed, it shall not be put into production and use. In the case of any major change in the construction content and energy efficiency level of a fixed-asset investment project passing energy conservation examination, the construction entity shall file an amendment application with the energy conservation examination authority. Shanghai, Beijing, Shenzhen, Guangdong, Chengdu, Hebei, Jiangsu, Inner Mongolia and other provinces and cities have formulated detailed regulations on the examination of energy conservation of fixed-asset investment within their jurisdictions, and reinforced interim and post-filing supervision. New regulations, policies and rules have been issued with respect to the construction or development of new data centers, and rebuilding or expansion of existing data centers. For example, on January 21, 2019, the MIIT, the National Government Office Administration and National Energy Administration jointly published the Guidance on Promotion of Green Data Center Construction, pursuant to which authorities encourage data centers to adhere to certain average levels of energy conservation and aim to reach several goals including, among others, reaching the PUE of newly constructed large and extra-large data centers at or below 1.4 as of the year 2022. On September 6, 2018, the GOPGB, issued the Beijing Municipality’s Catalogue for the Prohibition and Restriction of Newly Increased Industries (2018 Edition), or the 2018 Catalogue, which is a revised edition of the catalogue GOPGB issued in 2015. The 2018 Catalogue prohibits new construction or expansion within Beijing’s municipal boundaries of data centers which are involved in providing internet data services or information processing and storage support services, except for cloud computing data centers with PUE lower than 1.4. In addition, new construction or expansion of data centers which are involved in providing internet data services or information processing and storage support services with PUE lower than 1.4 is also prohibited within the boundaries of Beijing’s Dongcheng District, Xicheng District, Chaoyang District, Haidian District, Fengtai District, Shijingshan District and Tongzhou New Town. On January 2, 2019, the Shanghai CEI and the Shanghai DRC jointly issued the Guideline Opinion on Coordinated Construction of Internet Data Centers in Shanghai, pursuant to which the aggregate number of newly increased IDC racks within the period from 2019 to 2020 in Shanghai should be controlled to no more than 60,000, and the PUE of newly constructed internet data centers should be at or below 1.3 and reconstructed internet data centers be at or below 1.4. On April 11, 2019, the Shenzhen DRC published a Notice on the Relevant Matters of Energy Conservation Examination for Data Centers, pursuant to which key energy consumption entities (defined as those that consume the equivalent of more than 5,000 tons of standard coal in energy) should establish an online supervision system for energy consumption and access to Guangdong’s platform for supervising such key energy consumption entities. The Notice also specifies that the newly increased amount of annual comprehensive energy consumption of data centers should be strictly controlled and the practical replacement amount for newly increased amount of energy consumption will be supported based on the PUE of the data centers. Regulations Related to Information Security and Confidentiality of User Information Internet activities in China are regulated and restricted by the PRC government and are subject to penalties under the Decision Regarding the Protection of Internet Security, promulgated by the SCNPC on December 28, 2000 and amended on August 27, 2009. The Ministry of Public Security, or the MPS, has promulgated measures that prohibit use of the internet in ways that, among other things, divulge government secrets or disseminate socially destabilizing content. The MPS and its local counterparts have authority to supervise and inspect domestic websites to implement its measures. Internet information service providers that violate these measures may have their licenses revoked and their websites shut down. On June 22, 2007, the MPS, the State Secrecy Administration and other relevant authorities jointly issued the Administrative Measures for the Hierarchical Protection of Information Security, which divides information systems into five categories and requires the operators of information systems ranking above Grade II to file an application with the local Bureau of Public Security within 30 days of the date of its security protection grade determination or since its operation. 83 The PRC government regulates the security and confidentiality of internet users’ information. The Administrative Measures on Internet Information Service promulgated by the State Council on September 25, 2000 and amended on January 8, 2011, the Regulations on Technical Measures of Internet Security Protection promulgated by the Ministry of Public Security on December 13, 2005 and the Provisions on Protecting Personal Information of Telecommunication and Internet Users promulgated by the MIIT on July 16, 2013 set forth strict requirements to protect personal information of internet users and require internet information service providers to maintain adequate systems to protect the security of such information. Personal information collected must be used only in connection with the services provided by the internet information service provider. Moreover, the Rules for Regulating the Order in the Market for Internet Information Service which was promulgated by the MIIT on December 29, 2011 and came into effect on March 15, 2012 also protect internet users’ personal information by (i) prohibiting internet information service providers from unauthorized collection, disclosure or use of their users’ personal information and (ii) requiring internet information service providers to take measures to safeguard their users’ personal information. The Cyber Security Law of the People’s Republic of China, or the Cyber Security Law, which was approved by the SCNPC, came into effect on June 1, 2017, which provides certain rules and requirements applicable to network service providers in China. The Cyber Security Law requires network operators to perform certain functions related to cyber security protection and strengthening network information management by taking technical and other necessary measures as required by laws and regulations to safeguard the operation of networks, effectively addressing network security, preventing illegal and criminal activities, and maintaining the integrity, confidentiality and usability of network data. In addition, the Cyber Security Law imposes certain requirements on network operators of critical information infrastructure, including that such network operators with operations in the PRC shall store personal information and important data collected and produced within the territory of PRC, and shall perform certain security obligations as required under the Cyber Security Law. Regulations Related to Leases According to the Contract Law of the People’s Republic of China promulgated by the National People’s Congress on March 15, 1999 and effective from October 1, 1999, the lease agreement shall be in writing if its term is over six months, and the term of any lease agreement shall not exceed twenty years. During the lease term, any change of ownership to the leased property does not affect the validity of the lease contract. The tenant may sub-let the leased property if it is agreed by the landlord and the lease agreement between the landlord and the tenant is still valid and binding. When the landlord is to sell a leased housing under a lease agreement, it shall give the tenant a reasonable advance notice before the sale, and the tenant has the priority to buy such leased housing on equal conditions. The tenant must pay rent on time in accordance with the lease contract. In the event of default of rental payment without reasonable cause, the landlord may ask the tenant to pay within a reasonable period of time, failing which the landlord may terminate the lease. The landlord has the right to terminate the lease agreement if the tenant sub-lets the property without consent from the landlord, or causes loss to the leased properties resulting from its using the property not in compliance with the usage as stipulated in the lease agreement, or defaults in rental payment after the reasonable period as required by the landlord, or other circumstances occurs allowing the landlord terminate the lease agreement under relevant PRC laws and regulations, or otherwise, if the landlord wishes to terminate the lease before its expiry date, prior consent shall be obtained from the tenants. On December 1, 2010, Ministry of Housing and Urban-Rural Development promulgated the Administrative Measures for Leasing of Commodity Housing, which became effective on February 1, 2011. According to such measures, the landlords and tenants are required to enter into lease contracts which should generally contain specified provisions, and the lease contract should be registered with the relevant construction or property authorities at municipal or county level within 30 days after its conclusion. If the lease contract is extended or terminated or if there is any change to the registered items, the landlord and the tenant are required to effect alteration registration, extension of registration or deregistration with the relevant construction or property authorities within 30 days after the occurrence of the extension, termination or alteration. Regulations Related to Intellectual Property Rights The State Council and the National Copyright Administration, or the NCAC, have promulgated various rules and regulations relating to the protection of software in China. Under these rules and regulations, software owners, licensees and transferees may register their rights in software with the NCAC or its local branches and obtain software copyright registration certificates. Although such registration is not mandatory under PRC law, software owners, licensees and transferees are encouraged to go through the registration process to enjoy the better protections afforded to registered software rights. 84 The PRC Trademark Law, adopted in 1982 and revised in 1993, 2001, 2013 and 2019 respectively, with its implementation rules adopted in 2002 and revised in 2014, protects registered trademarks. The PRC Trademark Office of the State Administration for Industry and Commerce handles trademark registrations and grants a protection term of ten years to registered trademarks. On August 24, 2017, the MIIT replaced the Administrative Measures on China Internet Domain Names promulgated on November 5, 2004 with the Administration Measures of Internet Domain Names, which took effect on November 1, 2017. According to these measures, the MIIT is in charge of the overall administration of domain names in China. The registration of domain names in PRC is on a “first-apply-first-registration” basis. A domain name applicant will become the domain name holder upon the completion of the application procedure. On March 12, 1984, the SCNPC promulgated the Patent Law, which was amended in 1992, 2000 and 2008. On June 15, 2001, the State Council promulgated the Implementation Regulation for the Patent Law, which was amended on January 9, 2010. According to these laws and regulations, the State Intellectual Property Office is responsible for administering patents in the PRC. The Chinese patent system is premised upon the “first to file” principle, which means that where more than one person files a patent application for the same invention, a patent will be granted to the person who filed the application first. To be patentable, invention or utility models must meet three conditions: novelty, inventiveness and practical applicability. A patent is valid for 20 years in the case of an invention, and for ten years in the case of utility models and designs. A third-party user must obtain consent or a proper license from the patent owner in order to use the patent. Regulations Related to Employment On June 29, 2007, the SCNPC, adopted the Labor Contract Law, or LCL, which became effective as of January 1, 2008 and was revised on December 28, 2012 (effective from July 1, 2013). The LCL requires employers to enter into written contracts with their employees, restricts the use of temporary workers and aims to give employees long-term job security. Pursuant to the LCL, employment contracts lawfully concluded prior to the implementation of the LCL and continuing as of the date of its implementation will continue to be performed. Where an employment relationship was established prior to the implementation of the LCL but no written employment contract was concluded, a contract must be concluded within one month after the LCL’s implementation. According to the Social Insurance Law promulgated by SCNPC which became effective from July 1, 2011 and was amended on December 29, 2018, the Regulation of Insurance for Work-Related Injury promulgated by the State Council on April 27, 2003 and amended on December 20, 2010, the Provisional Measures on Insurance for Maternity of Employees promulgated by the Ministry of Labor on December 14, 1994, the Regulation of Unemployment Insurance promulgated by the State Council on January 22, 1999, the Decision of the State Council on Setting Up Basic Medical Insurance System for Staff Members and Workers in Cities and Towns promulgated by the State Council on December 14, 1998, and the Interim Regulation on the Collection and Payment of Social Insurance Premiums promulgated by the State Council on January 22, 1999 and amended on March, 24, 2019, an employer is required to contribute the social insurance for its employees in the PRC, including the basic pension insurance, basic medical insurance, unemployment insurance, maternity insurance and injury insurance. Under the Regulations on the Administration of Housing Funds, promulgated by the State Council on April 3, 1999 and as amended on March 24, 2019, an employer is required to make contributions to a housing fund for its employees. Regulations Related to Foreign Currency Exchange and Dividend Distribution Foreign Currency Exchange The principal regulations governing foreign currency exchange in China are the Foreign Exchange Administration Regulations, promulgated by the State Council on January 29, 1996 (effective from April 1, 1996) as amended on August 5, 2008. Under this regulation, the State does not restrict the international payment and transfer for current account items, including the goods and service-related foreign exchange transactions and other current exchange transactions, but not for capital account items, such as direct investments, loans, capital transfer and investments in securities, unless the prior approval of the SAFE is obtained and prior registration with the SAFE is made. 85 Pursuant to the Administration Rules of the Settlement, Sale and Payment of Foreign Exchange promulgated on June 20, 1996 by the PBOC, foreign-invested enterprises in China may purchase or remit foreign currency for settlement of current account transactions without the approval of the SAFE. Foreign currency transactions under the capital account are still subject to limitations and require approvals from, or registration with, the SAFE and other relevant PRC governmental authorities. In addition, the Notice of the General Affairs Department of SAFE on The Relevant Operation Issues Concerning the Improvement of the Administration of Payment and Settlement of Foreign Currency Capital of Foreign-invested Enterprises, or Circular 142, which was promulgated on August 29, 2008 by SAFE, regulates the conversion by foreign-invested enterprises of foreign currency into Renminbi by restricting how the converted Renminbi may be used. Circular 142 requires that Renminbi converted from the foreign currency-denominated capital of a foreign-invested enterprise may only be used for purposes within the business scope approved by the relevant government authority and may not be used to make equity investments in PRC, unless specifically provided otherwise. The SAFE further strengthened its oversight over the flow and use of Renminbi funds converted from the foreign currency-denominated capital of a foreign-invested enterprise. The use of such Renminbi may not be changed without approval from the SAFE, and may not be used to repay Renminbi loans if the proceeds of such loans have not yet been used. Any violation of Circular 142 may result in severe penalties, including substantial fines. On November 19, 2012, SAFE promulgated the Circular of Further Improving and Adjusting Foreign Exchange Administration Policies on Foreign Direct Investment, which substantially amends and simplifies the current foreign exchange procedure. Pursuant to this circular, the opening of various special purpose foreign exchange accounts, such as pre-establishment expenses accounts, foreign exchange capital accounts and guarantee accounts, the reinvestment of Renminbi proceeds by foreign investors in the PRC, and remittance of foreign exchange profits and dividends by a foreign-invested enterprise to its foreign shareholders no longer require the approval or verification of SAFE, and multiple capital accounts for the same entity may be opened in different provinces, which was not possible previously. In addition, SAFE promulgated the Circular on Printing and Distributing the Provisions on Foreign Exchange Administration over Domestic Direct Investment by Foreign Investors and the Supporting Documents in May 2013, which specifies that the administration by SAFE or its local branches over direct investment by foreign investors in the PRC shall be conducted by way of registration and banks shall process foreign exchange business relating to the direct investment in the PRC based on the registration information provided by SAFE and its branches. In July 2014, SAFE decided to further reform the foreign exchange administration system in order to satisfy and facilitate the business and capital operations of foreign invested enterprises, and issued the Circular on the Relevant Issues Concerning the Launch of Reforming Trial of the Administration Model of the Settlement of Foreign Currency Capital of Foreign-Invested Enterprises in Certain Areas, or Circular 36, on August 4, 2014. This circular suspends the application of Circular 142 in certain areas and allows a foreign-invested enterprise registered in such areas to use the Renminbi capital converted from foreign currency registered capital for equity investments within the PRC. On March 30, 2015, SAFE released the Notice on the Reform of the Management Method for the Settlement of Foreign Exchange Capital of Foreign-invested Enterprises, or Circular 19, which has made certain adjustments to some regulatory requirements on the settlement of foreign exchange capital of foreign-invested enterprises, lifted some foreign exchange restrictions under Circular 142, and annulled Circular 142 and Circular 36. However, Circular 19 continues to, prohibit foreign-invested enterprises from, among other things, using Renminbi fund converted from its foreign exchange capitals for expenditure beyond its business scope, providing entrusted loans or repaying loans between non-financial enterprises. On June 9, 2016, SAFE issued the Circular of the State Administration of Foreign Exchange on Reforming and Regulating Policies on the Control over Foreign Exchange Settlement of Capital Accounts, or Circular 16, which took effect on the same day. Compared to Circular 19, Circular 16 not only provides that, in addition to foreign exchange capital, foreign debt funds and proceeds remitted from foreign listings should also be subject to the discretional foreign exchange settlement, but also lifted the restriction, that foreign exchange capital under the capital accounts and the corresponding Renminbi capital obtained from foreign exchange settlement should not be used for repaying the inter-enterprise borrowings (including advances by the third party) or repaying the bank loans in Renminbi that have been sub-lent to the third party. 86 On January 26, 2017, SAFE promulgated the Circular on Further Improving Reform of Foreign Exchange Administration and Optimizing Genuineness and Compliance Verification, or Circular 3, which stipulates several capital control measures with respect to the outbound remittance of profit from domestic entities to offshore entities, including (i) under the principle of genuine transactions, banks shall check board resolutions regarding profit distribution, original copies of tax filing records and audited financial statements; and (ii) domestic entities shall hold income to account for previous years’ losses before remitting any profits. Moreover, pursuant to Circular 3, domestic entities shall make detailed explanations of their sources of capital and utilization arrangements, and provide board resolutions, contracts and other proof when completing the registration procedures in connection with any outbound investments. On October 23, 2019, the SAFE promulgated the Notice for Further Advancing the Facilitation of Cross-border Trade and Investment, or Circular 28, which in principle, among other things, allows all foreign-invested companies to use Renminbi converted from foreign currency-denominated capital for equity investments in China, as long as the equity investment is genuine, does not violate applicable laws, and complies with the negative list on foreign investment. However, since Circular 28 is newly promulgated, it is unclear how SAFE and competent banks will implement this in practice. Circular 37 On July 4, 2014, SAFE promulgated the Circular on Relevant Issues Concerning Foreign Exchange Control on Domestic Residents’ Offshore Investment and Financing and Roundtrip Investment through Special Purpose Vehicles, or Circular 37, which replaced the former circular commonly known as Circular 75 promulgated by SAFE on October 21, 2005. Circular 37 requires PRC residents to register with local branches of SAFE in connection with their direct establishment or indirect control of an offshore entity, for the purpose of overseas investment and financing, with such PRC residents’ legally owned assets or equity interests in domestic enterprises or offshore assets or interests, referred to in Circular 37 as a “special purpose vehicle.” Circular 37 further requires amendment to the registration in the event of any significant changes with respect to the special purpose vehicle, such as increase or decrease of capital contributed by PRC individuals, share transfer or exchange, merger, division or other material event. In the event that a PRC shareholder holding interests in a special purpose vehicle fails to fulfill the required SAFE registration, the PRC subsidiaries of that special purpose vehicle may be prohibited from making profit distributions to the offshore parent and from carrying out subsequent cross-border foreign exchange activities, and the special purpose vehicle may be restricted in its ability to contribute additional capital into its PRC subsidiary. Furthermore, failure to comply with the various SAFE registration requirements described above could result in liability under PRC law for evasion of foreign exchange controls. On February 13, 2015, SAFE released the Notice on Further Simplifying and Improving Policies for the Foreign Exchange Administration of Direct Investment, or Circular 13 (effective from June 1, 2015, and partially invalid according to the Circular on Repeating and Invalidaing Five Normative Documents Concerning Administration of Foreign Exchange and some Articles of Seven Normative Documents Concerning Administration of Foreign Exchange promulgate by the SAFE on December 30, 2019), which has amended Circular 37 by requiring PRC residents or entities to register with qualified banks rather than SAFE or its local branch in connection with their establishment or control of an offshore entity established for the purpose of overseas investment or financing. Share Option Rules Under the Administration Measures on Individual Foreign Exchange Control issued by the PBOC on December 25, 2006 (effective from February 1, 2007), all foreign exchange matters involved in employee share ownership plans and share option plans in which PRC citizens participate require approval from SAFE or its authorized branch. Pursuant to Circular 37, PRC residents who participate in share incentive plans in overseas non-publicly-listed companies may submit applications to SAFE or its local branches for the foreign exchange registration with respect to offshore special purpose companies. In addition, under the Notices on Issues concerning the Foreign Exchange Administration for Domestic Individuals Participating in Share Incentive Plans of Overseas Publicly-Listed Companies issued by SAFE on February 15, 2012, or the Share Option Rules, PRC residents who are granted shares or share options by companies listed on overseas stock exchanges under share incentive plans are required to (i) register with SAFE or its local branches, (ii) retain a qualified PRC agent, which may be a PRC subsidiary of the overseas listed company or another qualified institution selected by the PRC subsidiary, to conduct the SAFE registration and other procedures with respect to the share incentive plans on behalf of the participants, and (iii) retain an overseas institution to handle matters in connection with their exercise of share options, purchase and sale of shares or interests and funds transfers. 87 Dividend Distribution The principal regulations governing the distribution of dividends paid by wholly foreign-owned enterprises include the Company Law of the PRC last amended on October 26, 2018, the Foreign Investment Law of the PRC issued on March 15, 2019 (effective from January 1, 2020) and the Regulations on Implementing the Foreign Investment Law issued on December 26, 2019 (effective from January 1, 2020). Under these regulations, wholly foreign-owned enterprises in China may pay dividends only out of their accumulated profits, if any, as determined in accordance with PRC accounting standards and regulations. In addition, a wholly foreign-owned enterprise in China is required to set aside at least 10% of its after-tax profit based on PRC accounting standards each year to its general reserves until its cumulative total reserve funds reaches 50% of its registered capital. These reserve funds, however, may not be distributed as cash dividends. Regulations Related to Taxation Enterprise Income Tax Prior to January 1, 2008, according to Provisional Regulations of the People’s Republic of China on Enterprises Income Tax promulgated by the State Council on December 13, 1993 and Income Tax Law of the People’s Republic of China for Enterprises with Foreign Investment and Foreign Enterprises promulgated by the National People’s Congress on April 9, 1991, entities established in the PRC were generally subject to a 30% national and 3% local enterprise income tax rate. Various preferential tax treatments promulgated by PRC tax authorities were available to foreign-invested enterprises. In March 2007, the National People’s Congress enacted the Enterprise Income Tax Law, which was amended in December 2018, and in December 2007 the State Council promulgated the Implementing Rules of the Enterprise Income Tax Law, or the Implementing Rules, which was amended in April 2019, both of which became effective on January 1, 2008. The Enterprise Income Tax Law (i) reduces the top rate of enterprise income tax from 33% to a uniform 25% rate applicable to both foreign-invested enterprises and domestic enterprises and eliminates many of the preferential tax policies afforded to foreign investors, (ii) permits companies to continue to enjoy their existing tax incentives, subject to certain transitional phase-out rules and (iii) introduces new tax incentives, subject to various qualification criteria. The Enterprise Income Tax Law also provides that enterprises organized under the laws of jurisdictions outside China with their “de facto management bodies” located within China may be considered PRC resident enterprises and therefore be subject to PRC enterprise income tax at the rate of 25% on their worldwide income. The Implementing Rules further define the term “de facto management body” as the management body that exercises substantial and overall management and control over the production and operations, personnel, accounts and properties of an enterprise. If an enterprise organized under the laws of jurisdiction outside China is considered a PRC resident enterprise for PRC enterprise income tax purposes, a number of unfavorable PRC tax consequences could follow. First, it would be subject to the PRC enterprise income tax at the rate of 25% on its worldwide income. Second, a 10% withholding tax would be imposed on dividends it pays to its non-PRC enterprise shareholders and with respect to gains derived by its non-PRC enterprise shareholders from transfer of its shares. 88 Prior to January 1, 2008, according to Income Tax Law of the People’s Republic of China for Enterprises with Foreign Investment and Foreign Enterprises promulgated by the National People’s Congress on April 9, 1991 dividends payable to foreign investors derived by foreign enterprises from business operations in China were exempted from PRC enterprise income tax. However, such exemption was revoked by the Enterprise Income Tax Law and dividends generated after January 1, 2008 and payable by a foreign-invested enterprise in China to its foreign enterprise investors are subject to a 10% withholding tax, unless any such foreign investor’s jurisdiction of incorporation has a tax treaty with China that provides for a preferential withholding arrangement. Pursuant to the Notice of the State Administration of Taxation on Negotiated Reduction of Dividends and Interest Rates, which was issued by the SAT on January 29, 2008 and supplemented and revised on February 29, 2008, and the Arrangement between Mainland China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation and Prevention of Fiscal Evasion with Respect to Taxes on Income, which became effective on December 8, 2006 and applies to income derived in any year of assessment commencing on or after April 1, 2007 in Hong Kong and in any year commencing on or after January 1, 2007 in the PRC, such withholding tax rate may be lowered to 5% if a Hong Kong enterprise is deemed the beneficial owner of any dividend paid by a PRC subsidiary by PRC tax authorities and holds at least 25% of the equity interest in that particular PRC subsidiary at all times within the 12-month period immediately before distribution of the dividends. Furthermore, according to the Circular on Several Questions regarding the “beneficial owner” in Tax Treaties, which was issued by the SAT on February 3, 2018 and became effective on April 1, 2018, when determining an applicant’s status as a “beneficial owner” regarding tax treatments in connection with dividends, interest or royalties in the tax treaties, several factors, including without limitation, whether the applicant is obligated to pay more than 50% of his or her income in twelve months to residents in other countries or regions, whether the business operated by the applicant constitutes actual business activities, and whether the country or region which is a counterparty to the tax treaty does not levy any tax, grants tax exemption on relevant income, or levies tax at an extremely low rate, will be taken into account. Such factors will be analyzed according to the actual circumstances of each specific case. This circular further provides that applicants who intend to prove his or her status as a “beneficial owner” shall submit relevant documents to the relevant tax bureau according to the Announcement on Issuing the Measures for the Administration of Non-Resident Taxpayers’ Enjoyment of the Treatment under Agreements issued by the SAT on October 14, 2019. Value-Added Tax and Business Tax Pursuant to Provisional Regulations of the People’s Republic of China on Business Tax promulgated by the State Council on December 13, 1993 and annulled on November 19, 2017, any entity or individual conducting business in the service industry is generally required to pay a business tax at the rate of 5% on the revenues generated from providing such services. However, if the services provided are related to technology development and transfer, such business tax may be exempted subject to approval by the relevant tax authorities. Whereas, pursuant to the Provisional Regulations on Value-Added Tax of the PRC and its implementation regulations, unless otherwise specified by relevant laws and regulations, any entity or individual engaged in the sales of goods, provision of processing, repairs and replacement services, sales of services, intangible assets and real properties, and importation of goods are generally required to pay a value-added tax, or VAT. In November 2011, the Ministry of Finance and the SAT promulgated the Pilot Plan for Imposition of Value-Added Tax to Replace Business Tax. In March 2016, the Ministry of Finance and the SAT further promulgated the Notice on Fully Promoting the Pilot Plan for Replacing Business Tax by Value-Added Tax, which became effective on May 1, 2016. Pursuant to the pilot plan and relevant notices, VAT is generally imposed in the modern service industries, including the VATS, on a nationwide basis. VAT of a rate of 6% applies to revenue derived from the provision of some modern services. Unlike business tax, a taxpayer is allowed to offset the qualified input VAT paid on taxable purchases against the output VAT chargeable on the modern services provided. In April 2018, the Ministry of Finance and the SAT jointly promulgated the Circular of the Ministry of Finance and the State Administration of Taxation on Adjustment of Value-Added Tax Rates, or Circular 32, according to which (i) for VAT taxable sales acts or importation of goods originally subject to value-added tax rates of 17% and 11%, respectively, such tax rates shall be adjusted to 16% and 10%, respectively; (ii) for purchase of agricultural products originally subject to deduction rate of 11%, such deduction rate shall be adjusted to 10%; (iii) for purchase of agricultural products for the purpose of production and sales or consigned processing of goods subject to tax rate of 16%, such tax shall be calculated at a deduction rate of 12%; (iv) for exported goods originally subject to tax rate of 17% and export tax refund rate of 17%, the export tax refund rate shall be adjusted to 16%; and (v) for exported goods and cross-border taxable acts originally subject to tax rate of 11% and export tax refund rate of 11%, the export tax refund rate shall be adjusted to 10%. Circular 32 became effective on May 1, 2018 and shall supersede existing provisions which are inconsistent with Circular 32. 89 In March 2019, the Ministry of Finance, the SAT and General Administration of Customs jointly promulgated the Announcement on Policies for Deepening the VAT Reform, or Circular 39, according to which (i) for VAT taxable sales acts or importation of goods originally subject to value-added tax rates of 16% and 10% respectively, such tax rates shall be adjusted to 13% and 9%, respectively; (ii) for purchase of agricultural products originally subject to deduction rate of 10%, such deduction rate shall be adjusted to 9%; (iii) for purchase of agricultural products for the purpose of production and sales or consigned processing of goods subject to tax rate of 13%, such tax shall be calculated at the deduction rate of 10%; (iv) for exported goods originally subject to tax rate of 16% and export tax refund rate of 16%, the export tax refund rate shall be adjusted to 13%; and (v) for exported goods and cross-border taxable acts originally subject to tax rate of 10% and export tax refund rate of 10%, the export tax refund rate shall be adjusted to 9%. Circular 39 became effective on April 1, 2019 and shall supersede existing provisions which are inconsistent with Circular 39. Regulations Related to M&A and Overseas Listings On August 8, 2006, six PRC regulatory agencies, including the MOFCOM, the State-owned Assets Supervision and Administration Commission, the SAT, the SAIC, the CSRC, and the SAFE, jointly issued the Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the M&A Rules, which became effective on September 8, 2006 and was amended on June 22, 2009. The M&A Rules, among other things, require that (i) PRC entities or individuals obtain MOFCOM approval before they establish or control a special purpose vehicle, or SPV, overseas, provided that they intend to use the SPV to acquire their equity interests in a PRC company at the consideration of newly issued share of the SPV, or Share Swap, and list their equity interests in the PRC company overseas by listing the SPV in an overseas market; (ii) the SPV obtains MOFCOM’s approval before it acquires the equity interests held by the PRC entities or PRC individual in the PRC company by Share Swap; and (iii) the SPV obtains CSRC approval before it lists overseas. C. Organizational Structure Our Corporate Structure In order to comply with PRC regulations, particularly those with respect to restrictions on foreign ownership in entities providing IDC services and foreign exchange control, our preferred approach to structuring our data center operations and investments in China is to have VIEs and their subsidiaries which hold VATS licenses and provide services to customers and data center companies established as wholly foreign owned enterprises under the PRC Law which hold the data center property interests and assets. Our VIEs include Management HoldCo, GDS Shanghal, GDS Beijing, and 16 direct and indirect subsidiaries of GDS Beijing. The reasons we have various VIEs and their subsidairies are due to the historical development of our corporate structure at the early stage of GDS with different VIEs to serve different regions before certain of our VIEs obtained cross-regional VATS licenses, our internal restructuring conducted to comply with regulatory requirements and our various acquisitions of companies licensed to provide IDC services. See “Item 4. Information on the Company—A. History and Development of the Company”. For historical reasons and as a result of our acquisitions, several direct and indirect subsidiaries of GDS Beijing also hold data center property interests and assets. GDS Beijing, GDS Shanghai, Management HoldCo and their shareholders, have a contractual relationship with GDS Investment Company, which is the investment holding company we use to manage and control our overall data center business in the PRC. In addition, for our data centers in China, in order to comply with PRC regulatory requirements, particularly those with respect to company registration and tax filing, as well as local government requirements, and to facilitate the onshore financing of our data centers by financial institutions in the PRC which is generally provided on an individual data center basis, we generally establish one wholly foreign owned enterprise at the district where the data center is located to hold the property interests and assets for such data center. In a small number of cases, we establish one wholly foreign owned enterprise to hold the property interests and assets for two to three data centers located at the same or adjacent premises. Furthermore, in order to provide flexibility for obtaining offshore financing for our data centers, which usually requires the pledge of the shares of the holding companies of data centers as collateral, we usually establish Hong Kong holding companies to separately hold the equity interest of the wholly foreign owned enterprises. The following diagrams illustrate our corporate structure as of December 31, 2019. They omit certain entities that are immaterial to our results of operations, business and financial condition. Equity interests depicted in these diagrams are held as to 100%, except where noted. The relationships between each of GDS Shanghai and GDS Beijing, Management HoldCo and GDS Investment Company as illustrated in this diagram are governed by contractual arrangements and do not constitute equity ownership. 90 91 (1) Includes 43 direct and indirect subsidiaries incorporated in Hong Kong and 4 direct subsidiaries incorporated in the British Virgin Islands, Macau and Singapore, respectively. See the chart below for details on the data center holding companies. (2) Comprises 42 direct and indirect subsidiaries incorporated in China. See the chart below for details on the data center holding companies and their subsidiaries in China. (3) GDS Investment Company also holds equity interests of 23 subsidiaries in China. See the below chart for details on the subsidiaries of GDS Investment Company. (4) Each of the five management shareholders, namely Yilin Chen, Yan Liang, Liang Chen, Andy Wenfeng Li and Qi Wang, holds 20% of the total equity interests in Management HoldCo. (5) GDS Beijing holds equity interests of 1% in Zhangbei Yuntong Data Technology Co, Ltd., or Zhangbei Yuntong, and GDS Suzhou holds equity interests of 99% in Zhangbei Yuntong. (6) Weiteng Services, Weiteng Network, EDC Shanghai Waigaoqiao, Shanghai Cai Tuo and Zhangbei Yuntong operate the GZ1, GZ2, SH1, SH11 and ZB1/2/3 data centers, respectively. (7) In addition to the entities shown in the above diagram, GDS Shanghai holds a 20% equity interest in Wan Bo Zhi Yun Information Technology (Shanghai) Co., Ltd., or Wanbo. GDS Shanghai jointly invested in Wanbo alongside two third-party shareholders, Shanghai Yan Hua Data Technology Co., Ltd and Shanghai Yue Ang Enterprise Management Consulting Center in March 2019. The main business scope of Wanbo is to provide cloud-related services, including cloud migration, consultancy services, and resale of public cloud services offered by major cloud providers in China, including certain of our major customers. Except for the data centers listed in footnote 6 to the diagram above (i.e., GZ1, GZ2, SH1, SH11 and ZB1/2/3, which are operated by the direct and indirect subsidiaries of GDS Beijing as indicated in footnote 6), our data centers are operated by the data center companies indicated in the diagram above, which in turn are held by data center holding companies indicated in the diagram above. The following diagrams illustrate the structure and details of the data center holding companies and the data center companies established as wholly foreign owned enterprises that they hold respectively. Due to page size limitations, we have split the complete diagram into the following two parts: (1) GDS Investment Company holds a 98.4% equity interest in Beijing Shou Rong Yun, and LINKDC PTE. LTD. holds a 1.6% equity interest in Beijing Shou Rong Yun. (2) GDS Investment Company holds a 95% equity interest in Shanghai Shulan, the data center company for SH13. We will increase our equity interest to 100% when certain conditions are fulfilled by the landlord. 92 93 The following table sets forth the full legal names of the data center holding companies and corresponding data center companies, and corresponding data centers as of December 31, 2019: Data center holding company EDS (HK) Limited EDB II (HK) Limited FEP (HK) Limited EDE I (HK) Limited EDKS (HK) Limited EDC China Holdings Limited EDH (HK) Limited EDE II (HK) Limited EDCD (HK) Limited Data center company Shenzhen Yungang EDC Technology Co., Ltd., or EDC Shenzhen Beijing Hengpu’an Data Technology Development Co., Ltd., or EDC Beijing Heng Pu An Data center Shenzhen data centers SZ1, SZ2 and SZ3 Beijing data centers BJ1 and BJ2 Beijing Hengchang Data Technology Co., Ltd., or EDC Beijing Beijing data center BJ3 Hengchang Guojin Technology (Kunshan) Co., Ltd., or EDC Guojin Shanghai Yungang EDC Technology Co., Ltd., or EDC Shanghai Kunshan data center KS2 and KS3 Shanghai data center SH2 and SH3 Yungang Shenzhen Pingshan New Area Global Data Science & Technology Development Co., Ltd., or EDC Shenzhen Pingshan EDC (Chengdu) Industry Co., Ltd., or EDC Chengdu EDC Technology (Kunshan) Co., Ltd., or EDC Kunshan Shanghai Shuchang Data Science & Technology Co., Ltd., or Shanghai Shuchang Shenzhen data center SZ4 Chengdu data center CD1 and CD2 Kunshan data center KS1 Shanghai data center SH4 Shanghai Wanshu Data Technology Co., Ltd., or EDC Shanghai Wanshu Shanghai Puchang Data Science & Technology Co., Ltd., or Shanghai Shanghai data center SH5 Shanghai data centers SH6 and SH7 Puchang EBSD (HK) Limited Shanghai Shuyao Digital Technology Development Co., Ltd., or Shanghai Shanghai data center SH8 Shuyao EDP (HK) Limited EDSN (HK) Limited EBG (HK) Limited Shanghai Shuge Data Technology Co., Ltd., or Shanghai Shuge Shanghai Lingying Data Technology Co., Ltd., or Shanghai Lingying Beijing Wan Qing Teng Science & Technology Co., Ltd., or Beijing Wan Shanghai data center SH9, SH10 Shanghai data center SH12 Beijing data center BJ5 Qing Teng EDQ III (HK) Limited Langfang Shucheng Data Science & Technology Co., Ltd., or Langfang Langfang data center LF3 PSDC Limited RDTJ (HK) Limited EDF II (HK) Limited Shenzhen Qian Hai Wan Chang Technology Services Co., Ltd.

Key Information—D. Risk Factors” and elsewhere in this annual report on Form 20-F. 98 Overview We are a leading developer and operator of high-performance data centers in China. Our facilities are strategically located in China’s primary economic hubs where demand for high-performance data center services is concentrated. We also build-to-suit and operate data centers at lower-tier locations selected by our customers in order to fulfill their broader requirements. Our data centers have large net floor area, high power capacity, density and efficiency, and multiple redundancy across all critical systems. We are carrier and cloud-neutral, which enables our customers to access all the major PRC telecommunications networks, as well as the largest PRC and global public clouds which we host in many of our facilities. We offer colocation and managed services, including direct private connection to leading public clouds, an innovative service platform for managing hybrid clouds and, where required, the resale of public cloud services. We have a 19-year track record of service delivery, successfully fulfilling the requirements of some of the largest and most demanding customers for outsourced data center services in China. Our base of 624 customers consists predominantly of hyperscale cloud service providers, large internet companies, financial institutions, telecommunications carriers and IT service providers, and large domestic private sector and multinational corporations. As of December 31, 2019, we had an aggregate net floor area of 225,963 sqm in service, 91.9% of which was committed by customers, and an aggregate net floor area of 89,834 sqm under construction, 63.6% of which was pre-committed by customers, in each case excluding joint venture data centers. As of December 31, 2019, we had an additional aggregate net floor area of approximately 3,900 sqm in service and approximately 7,800 sqm under construction at joint venture data centers, 100% of which was committed or pre-committed by customers. We have experienced significant growth in recent years. Our net revenue grew from RMB1,616.2 million in 2017 to RMB2,792.1 million in 2018, representing an increase of 72.8%, and increased to RMB4,122.4 million (US$592.1 million) in 2019, representing an increase of 47.6%. Our net revenues from colocation services were RMB1,219.1 million, RMB2,104.3 million and RMB3,261.7 (US$468.5 million) in 2017, 2018 and 2019, representing 75.4%, 75.4% and 79.1% of total net revenue over the same periods, respectively. Our net revenues from managed services and other services were RMB372.8 million, RMB655.2 million and RMB832.8 (US$119.6 million) in 2017, 2018 and 2019, representing 23.1%, 23.4% and 20.2% of total net revenue over the same periods, respectively. Our net revenue from IT equipment sales were RMB24.3 million, RMB32.6 million and RMB27.9 million (US$4.0 million) in 2017, 2018 and 2019, representing 1.5%, 1.2% and 0.7% of total net revenue, respectively. Our net loss increased from RMB326.9 million in 2017 to RMB430.3 million in 2018, and increased to RMB442.1 million (US$63.5 million) in 2019. Our adjusted EBITDA increased from RMB512.3 million in 2017 to RMB1,046.5 million 2018, and increased to RMB1,824.0 million (US$262.0 million) in 2019. As of December 31, 2018 and 2019, our accumulated deficit was RMB1,615.1 million and RMB2,057.2 million (US$295.5 million), respectively. Key Factors Affecting Our Results of Operations Our business and results of operations are generally affected by the development of China’s data center services market. We have benefited from rapid growth in this market during recent years and any adverse changes in the data center services market in China may harm our business and results of operations. In addition, we believe that our results of operations are directly affected by the following key factors. Ability to Source and Develop Data Centers Our revenue growth depends on our ability to source and develop additional data centers. As it typically takes a minimum of twelve to eighteen months to develop a data center together with racks and equipment installed, we must commit to development in advance of realizing a benefit from our investment. We endeavor to ensure continuous availability of data center capacity to satisfy customer demand by maintaining a supply of high-performance data centers in various stages of development—from developing a pipeline of sites, to identifying appropriate sites, to data centers under construction to available net floor areas in existing data centers. We expand our sourcing of new data center area by (i) acquiring or leasing property which we develop for use as data center facilities, whether through constructing on greenfield land, redeveloping brownfield sites, converting existing industrial buildings, or fitting out and equipping purpose-built building shells, (ii) leasing existing data center capacity from third-party wholesale providers, and (iii) acquiring high-performance data centers from other companies. Our ability to maintain a growing supply of data center assets directly affects our revenue growth potential. If we are unable to obtain suitable land or buildings for new data centers or to do so at an acceptable cost to us or experience delays or increased costs during the data center design and construction development process which includes securing the power and relevant energy quota, our ability to grow our revenue and improve our results of operations would be negatively affected. Additionally, if demand slows unexpectedly or we source and develop data centers too rapidly, the resulting overcapacity would adversely affect our results of operations. 99 Ability to Secure Commitments for Data Center Services from Our Customers and Minimize Move-in Periods Due to the lengthy time period required to build data centers and the long-term nature of these investments, if we overestimate market demand for data center capacity, our utilization rate, which is the ratio of area utilized to area in service would be reduced, which would adversely affect our results of operations. Our revenue growth depends on our ability to secure commitments for our data center services. We focus on obtaining these commitments during the construction phase by entering into pre-commitment agreements with customers and endeavor to maximize total area committed. While providing flexibility to customers, we also aim to minimize move-in period so as to provide billable services and to start generating revenue as we typically charge our cloud service provider and large internet customers variable considerations that are primarily based on the customers’ usage of such services. Accordingly, our results of operations are highly influenced by our ability to maintain a high utilization rate. Our total area committed increased from 102,528 sqm as of December 31, 2017 to 183,743 sqm as of December 31, 2018, and further to 264,878 sqm as of December 31, 2019, while area utilized increased from 61,713 sqm as of December 31, 2017 to 108,326 sqm as of December 31, 2018, and further to 156,022 sqm as of December 31, 2019, in each case excluding joint venture data centers. Move-in periods, and minimum commitments over the move-in period, vary significantly from customer to customer. We strive to optimize our customer mix to achieve high commitment rates and utilization rates and a high proportion of long-term relationships. Pricing Structure and Power Costs Our results of operations will be affected by our ability to operate our data centers efficiently in terms of power consumption. Our data centers require significant levels of power supply to support their operations. Depending on the agreement, we agree with our customer to either charge them for actual power consumed or we factor it into a fixed price. Accordingly, the customer’s actual power usage during the life of the agreement will affect its profitability to us. Optimal configuration of customers and power usage within each data center will affect our results of operations. Utilization of Existing Capacity Our ability to maximize profitability depends on attaining high utilization of data center net floor area and power capacity. A substantial majority of our cost of revenue and operating expenses are fixed in nature. Such costs increase with each new data center and entail additional power commitment costs, depreciation from new property plant and equipment, rental costs on leased facilities and land use rights, personnel costs, and start-up costs. By adopting a modular development approach, we aim to optimize resource utilization and maximize capital efficiency to improve profitability. Cost Structure Depending on Data Center Tenure and Location We hold our data centers through a mix of those that we own or lease. The leases typically range from three years for third- party data centers to twenty years for self-developed data centers, all with different renewal periods. The tenure of the leases and the periods during which the amount are fixed or capped under the leases will affect our cost structure in the future. In addition, if many of our data centers continue to be located close to central business districts, where rental costs are generally higher, our cost structure will also be affected. Ability to Manage Our Development Costs Our ability to maximize our revenue depends on our ability to develop data centers on an economically feasible basis. We regularly monitor and review our equipment and construction costs related to our data center development capital expenditures to ensure we can optimize our cash outlay for capital expenditure. Our ability to manage an efficient supply chain will improve our cost of development and construction time. As part of our initiatives to improve the cost efficiency of our capital expenditure, we also participate in bulk purchasing programs for certain equipment with our strategic shareholders and major customers to leverage larger volume purchases to obtain a cost advantage. 100 Data Center Development and Financing Costs Our revenue growth depends on our ability to develop data centers at commercially acceptable terms. We have historically funded data center development through additional equity or debt financing. We expect to continue to fund future developments through debt financing or through the issuance of additional equity securities if necessary and when market conditions permit. Such additional financing may not be available, may not be on commercially acceptable terms or may result in an increase to our financing costs. In addition, we may encounter development delays, excess development costs, or challenges in attracting or retaining customers to use our data center services. We also may not be able to secure suitable land or buildings for new data centers or at a cost or terms acceptable to us. Ability to Identify and Acquire Other Business We have grown our business through acquisitions in the past and intend to continue selectively pursuing strategic partnerships and acquisitions to expand our business. Our ability to sustain our growth and maintain our competitive position may be affected by our ability to identify, acquire and successfully integrate other businesses and, if necessary, to obtain satisfactory debt or equity financing to fund those acquisitions. Key Performance Indicators Our net revenue and results of operations are largely determined by the amount of data center area in service, the degree to which data center capacity is committed or pre-committed as well as its utilization. Accordingly, our management uses the following key performance indicators as measures to evaluate our performance: Area in service: the entire net floor area of data centers (or phases of data centers) which are ready for service. Area under construction: the entire net floor area of data centers (or phases of data centers) which are actively under construction and have not yet reached the stage of being ready for service. Area committed: that part of our area in service which is committed to customers pursuant to customer agreements remaining in effect. Area pre-committed: that part of our area under construction which is pre-committed to customers pursuant to customer agreements remaining in effect. Total area committed: the sum of area committed and area pre-committed. Commitment rate: the ratio of area committed to area in service. Pre-commitment rate: the ratio of area pre-committed to area under construction. Area utilized: that part of our area in service that is committed to customers and revenue generating pursuant to the terms of customer agreements remaining in effect. Utilization rate: the ratio of area utilized to area in service. 101 The following table sets forth our key performance indicators for our data center portfolio (excluding joint venture data centers) as of December 31, 2017, 2018 and 2019. (Sqm, %) Area in service Area under construction Area committed Area pre-committed Total area committed Commitment rate Pre-commitment rate Area utilized Utilization rate 2017 101,258 24,505 92,961 (1) 9,567 (1) 102,528 (1) 91.8 % 39.0 % As of December 31, 2018 160,356 65,201 152,163 (1) 31,580 (1) 183,743 (1) 94.9 % 48.4 % 2019 225,963 (2) 89,834 (2) 207,716 (1) (2) 57,162 (1) (2) 264,878 (1) (2) 91.9 % 63.6 % 61,713 108,326 156,022 60.9 % 67.6 % 69.0 % (1) Includes data center area for which we have entered into non-binding agreements or letters of intent with, or have received other confirmations from, certain customers. (2) Excludes approximately 3,900 sqm net floor area relating to a joint venture data center in service, 100% of which was committed and approximately 7,800 sqm net floor area relating to joint venture data centers under construction, 100% of which was pre-committed as of December 31, 2019. Description of Selected Statement of Operations Items The following table sets forth our net revenue, cost of revenue and gross profit, both in an absolute amount and as a percentage of net revenue, for the years indicated. Year Ended December 31, 2017 2018 RMB % of Net Revenue % of Net RMB Revenue (in thousands, except for percentages) RMB 2019 US$ % of Net Revenue Net revenue Service revenue IT equipment sales Total Cost of revenue Gross profit Net Revenue 1,591,860 24,306 1,616,166 (1,207,694) 408,472 2,759,490 98.5 32,587 1.5 2,792,077 100.0 (74.7) (2,169,636) 622,441 25.3 4,094,571 27,834 4,122,405 588,148 98.8 3,998 1.2 592,146 100.0 (77.7) (3,079,679) (442,368) 149,778 22.3 1,042,726 99.3 0.7 100.0 (74.7) 25.3 We derive net revenue primarily from colocation services and, to a lesser extent, managed services, including managed hosting and managed cloud services. In addition, from time to time, we also sell IT equipment on a stand-alone basis or bundled in a managed service agreement to customers and provide consulting services. Substantially all of our service revenue is recognized on a recurring basis. Our colocation services primarily comprise the provision of space, power and cooling to our customers for housing servers and related IT equipment. Our customers have several choices for hosting their networking, server and storage equipment. They can place the equipment in a shared or private space that can be customized to their requirements. We offer power options customized to a customer’s individual power requirement. Our managed services include managed hosting and managed cloud services. Our managed hosting services comprise a broad range of value-added services, covering each layer of the data center IT value chain. Our suite of managed hosting services includes technical services, network management services, data storage services, system security services, database services and server middleware services. Our suite of managed cloud services includes direct private connection to leading public clouds, an innovative service platform for managing hybrid clouds and, where required, the resale of public cloud services. 102 Agreements with our cloud service provider and large internet customers typically charge variable considerations that are primarily based on customers’ usage of such services. Revenues under such variable consideration agreements are recognized based on the agreed usage-based fees as the services are rendered during the contract term. Agreements with our financial institution and enterprise customers typically charge a fixed amount which usually includes a stated amount of space, power commitment and other bundled services. Revenue under such fixed consideration agreements is recognized on a straight-line basis over the term of the contractual service period. We are subject to VAT at a rate of 6% on the IDC services we provide and 13% on equipment sales and power charges under the unbundled agreements, less any deductible VAT we have already paid or borne. We are also subject to surcharges on VAT payments in accordance with PRC law. During the periods presented, we were not subject to business tax on the services we provide. Revenue is recognized net of applicable VAT and related surcharges. We consider our customers to be the end users of our data center services. We may enter into agreements directly with our end user customers or through intermediate contracting parties. We have in the past derived, and believe that we will continue to derive, a significant portion of our total net revenue from a limited number of customers. We had one end user customer that generated 25.2% of our total net revenue in 2017, and two end user customers that generated 27.0% and 17.4% of our total net revenue, respectively, in 2018. We had three end user customers that generated 27.2%, 19.1% and 10.8% of our total net revenue, respectively, in 2019. No other end user customer accounted for 10% or more of our total net revenue during those periods. We expect our net revenue will continue to be highly dependent on a limited number of end user customers who account for a large percentage of our total area committed. As of December 31, 2019, we had three end user customers who accounted for 30.6%, 21.1% and 10.4%, respectively, of our total area committed (excluding joint venture data centers). Cost of Revenue Our cost of revenue consists primarily of utility costs, depreciation of property and equipment, rental costs related to our leased data centers, labor costs and others. Utility costs refer primarily to the cost of power needed to carry out our data center services. Depreciation of property and equipment primarily relates to depreciation of data center property and equipment, such as assets owned or acquired under finance leases, leasehold improvements to data centers and other long-lived assets. Rental costs relate to the data center capacity we lease under operating lease and use in providing services to our customers. Labor costs refer to compensation and benefit expenses for our engineering and operations personnel. These costs are largely fixed costs other than utility costs, for which there is a portion that varies proportionally to each customer’s power and utility consumption and a fixed portion consisting of a monthly power commitment fee. When a new data center comes into service, we mainly incur a level of fixed utility costs that are not directly correlated with net revenue. We expect that our cost of revenue will continue to increase as our business expands and we expect that utility costs, depreciation and amortization and rental costs will continue to comprise the largest portion of our cost of revenue. In addition, in any given period, the increase in our cost of revenue may also outpace the growth of our net revenue depending on the timing of the development of our data centers, our ability to secure customer agreements and the utilization rate of our data centers during the period. While we strive to both secure customer commitments to our data center services so that the most data center capacity will be utilized as possible and also to minimize the time as to when our data center area becomes operational and the customer occupies that area, these timing differences may result in fluctuation of our cost of revenue as a percentage of our net revenue between periods. 103 Operating Expenses Our operating expenses consist of selling and marketing expenses, general and administrative expenses, and research and development expenses. The following sets forth our selling and marketing expenses, general and administrative expenses and research and development expenses, both in an absolute amount and as a percentage of net revenue, for the years indicated. Year Ended December 31, 2017 2018 RMB % of Net Revenue RMB % of Net Revenue RMB Selling and marketing expenses General and administrative expenses Research and development expenses Total operating expenses Selling and Marketing Expenses 90,118 228,864 7,261 326,243 5.6 110,570 14.2 329,601 13,915 20.2 454,086 (in thousands, except for percentages) 4.0 129,901 11.8 411,418 21,627 16.3 562,946 0.5 0.4 2019 US$ % of Net Revenue 18,659 59,096 3,107 80,862 3.2 10.0 0.5 13.7 Our selling and marketing expenses consist primarily of compensation, including share-based compensation, and benefit expenses for our selling and marketing personnel, business development and promotion expenses and office and traveling expenses. As our business grows, we intend to increase the headcount of our selling and marketing staff and to continue to pursue aggressive branding and marketing campaigns and, as a result, our sales and marketing expenses are expected to increase. General and Administrative Expenses Our general and administrative expenses consist primarily of compensation, including share-based compensation, and benefit expenses for management and administrative personnel, start-up costs incurred prior to the operation of new data centers, depreciation and amortization, office and traveling expenses, professional fees and other fees. Depreciation relates primarily to our office equipment and facilities used by our management and staff in the administrative department. Start-up costs consist of costs incurred prior to commencement of operations of a new data center, including rental costs incurred pursuant to operating leases of buildings during the construction of leasehold improvements and other miscellaneous costs. Professional fees relate primarily to audit and legal expenses. We expect our general and administrative expenses to increase as we continue to increase our staff and office space as our business grows. In addition, as a public company, we have incurred increasing legal, accounting and other expenses, including costs associated with public company reporting requirements. We have also incurred costs in order to comply with the Sarbanes-Oxley Act of 2002 and the related rules and regulations implemented by the SEC and Nasdaq. We expect that such compliance, together with the growth and expansion of our business, will cause our general and administrative expenses to increase. Research and Development Expenses Research and development expenses consist primarily of compensation and benefit expenses for our research and development personnel. 104 Share-Based Compensation The table below shows the effect of the share-based compensation expenses on our cost of revenue and operating expense line items, both in an absolute amount and as a percentage of net revenues, for the years indicated. Cost of revenue Selling and marketing General and administrative Research and development Total share-based compensation expenses 2017 % of Net Revenue RMB Year Ended December 31, 2018 RMB % of Net Revenue RMB 2019 US$ % of Net Revenue 9,941 18,390 30,866 646 59,843 (in thousands, except for percentages) 46,007 18,008 0.6 0.6 0.9 25,213 39,436 1.1 2.2 101,949 61,707 1.9 0.1 0.1 2,364 949 3.8 189,756 3.7 105,877 6,608 5,665 14,644 340 27,257 1.1 0.9 2.5 0.1 4.6 We incurred higher share-based compensation expenses in 2019 as compared to 2018 due to grants of 12,941,952 restricted shares and 14,314,160 restricted shares in August 2018 and August 2019, respectively, to employees, officers and directors. We expect to continue to grant share options, restricted shares and other share-based awards under our share incentive plans and incur further share-based compensation expenses in future periods. See “—Critical Accounting Policies—Share-based Compensation” in this section for a description of what we account for the compensation cost from share-based payment transactions. Taxation Cayman Islands We are an exempted company incorporated in the Cayman Islands and conduct substantially all of our business through our PRC subsidiaries in the PRC. Under the current laws of the Cayman Islands, we are not subject to tax on income or capital gains. In addition, upon payment of dividends by us to our shareholders, no Cayman Islands withholding tax will be imposed. British Virgin Islands Under the current laws of the British Virgin Islands, we are not subject to tax on income or capital gains. In addition, upon payments of dividends by us to our shareholders, no British Virgin Islands withholding tax will be imposed. Hong Kong Our Hong Kong SAR entities are subject to the Hong Kong SAR profits tax at the rate of 16.5%. A two-tiered Profits Tax rates regime was introduced since year 2018 where the first HK$2.0 million of assessable profits earned will be taxed at half the current tax rate (8.25%) whilst the remaining profits will continue to be taxed at 16.5%. There is an anti-fragmentation measure where each group will have to nominate only one entity in the group to benefit from the progressive rates. Singapore Our subsidiaries in Singapore are subject to enterprise income tax on their taxable income in Singapore at a rate of 17%. PRC Generally, our subsidiaries and consolidated VIEs in China are subject to enterprise income tax on their taxable income in China at a rate of 25%. The enterprise income tax is calculated based on the entity’s global income as determined under PRC tax laws and accounting standards. 105 Dividends paid by our wholly foreign-owned subsidiaries in China to our intermediary holding company in Hong Kong will be subject to a withholding tax rate of 10%, unless the relevant Hong Kong entity satisfies all the requirements under the Arrangement between Mainland China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation and Prevention of Fiscal Evasion with Respect to Taxes on Income and receives approval from the relevant tax authority. If our Hong Kong subsidiary satisfies all the requirements under the tax arrangement and receives approval from the relevant tax authority, then the dividends paid to the Hong Kong subsidiary would be subject to withholding tax at the standard rate of 5%. Effective from November 1, 2015, the above mentioned approval requirement has been abolished, but a Hong Kong entity is still required to file an application package with the relevant tax authority, and settle overdue taxes if the preferential 5% tax rate is denied based on the subsequent review of the application package by the relevant tax authority. On October 14, 2019, SAT Announcement [2019] No. 35, Measures for the Administration of Non-Resident Taxpayers’ Enjoyment of Treaty Benefits, was issued to simplify the procedures for claiming China tax treaty benefits by non-resident taxpayers. If our holding company in the Cayman Islands or any of our subsidiaries outside of China were deemed to be a “resident enterprise” under the PRC Enterprise Income Tax Law, it would be subject to enterprise income tax on its worldwide income at a rate of 25%. See “Item 3. Key Information—D. Risk Factors—Risks Related to Doing Business in the People’s Republic of China—We may be treated as a resident enterprise for PRC tax purposes under the PRC Enterprise Income Tax Law, and we may therefore be subject to PRC income tax on our global income.” Effective from June 2014, all value-added telecommunication services provided in mainland China were subject to a VAT of 6% whereas basic telecommunication services are subject to a VAT of 11%. Effective from May 2018, the VAT rate on basic telecommunication services was replaced by a new rate of 10%, and is further replaced by the rate of 9% effective from April 2019. On March 20, 2019, the Ministry of Finance, the SAT and the General Administration of Customs jointly issued the Notice of Strengthening Reform of VAT Policies, or the Announcement No. 39. Pursuant to the Announcement No. 39, the generally applicable VAT rates are simplified to 13%, 9%, 6%, and nil, which became effective on April 1, 2019. In addition, a general VAT taxpayer is allowed to offset its qualified input VAT paid on taxable purchases against the output VAT chargeable on the telecommunication services and modern services provided by it. Critical Accounting Policies We prepare our financial statements in conformity with U.S. GAAP, which requires us to make judgments, estimates and assumptions. We continually evaluate these estimates and assumptions based on the most recently available information, our own historical experience and various other assumptions that we believe to be reasonable under the circumstances. Since the use of estimates is an integral component of the financial reporting process, actual results could differ from our expectations as a result of changes in our estimates. An accounting policy is considered critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time such estimate is made, and if different accounting estimates that reasonably could have been used, or changes in the accounting estimates that are reasonably likely to occur, could materially impact the consolidated financial statements. We believe that the following accounting policies involve a higher degree of judgment and complexity in their application and require us to make significant accounting estimates. The following descriptions of critical accounting policies, judgments and estimates should be read in conjunction with our consolidated financial statements and other disclosures included in this annual report on Form 20-F. 106 Consolidation of VIEs We account for entities qualifying as VIEs in accordance with Financial Accounting Standards Boards, or FASB, Accounting Standards Codification Topic 810, Consolidation, or ASC 810. Our operations are primarily conducted through our VIEs, Management HoldCo, GDS Beijing, GDS Beijing’s subsidiaries and GDS Shanghai, to comply with relevant PRC laws and regulations, which prohibit foreign investment in companies that are engaged in data center-related businesses in those regions. Individuals acting as nominee equity holders hold the legal equity interests of Management HoldCo on our behalf. The equity holders of Management HoldCo are Yilin Chen (senior vice president, product and service), Yan Liang (senior vice president, operation and delivery), Liang Chen (senior vice president, data center design), Andy Wenfeng Li (general counsel, compliance officer, and company secretary) and Qi Wang (head of cloud and network Business). Management HoldCo holds the legal equity interests of GDS Beijing and GDS Shanghai on our behalf. A series of contractual agreements, including equity interest pledge agreements, shareholder voting rights proxy agreements, exclusive technology license and service agreements, intellectual property rights license agreements, exclusive call option agreements and loan agreements, collectively, the VIE Agreements, were entered among GDS Investment Company, GDS Beijing, GDS Shanghai and Management HoldCo, as well as among GDS Investment Company, Management HoldCo and the equity holders of Management HoldCo. Through these agreements, Management HoldCo and the equity holders of Management HoldCo have granted all their legal rights, including voting rights, dividends rights, and disposition rights, of their equity interests in Management HoldCo, GDS Beijing and GDS Shanghai to us. Accordingly, Management HoldCo and the equity holders of Management HoldCo do not have (i) rights to make decisions about the activities of Management HoldCo, GDS Beijing and GDS Shanghai or (ii) rights to receive the expected residual returns of Management HoldCo, GDS Beijing and GDS Shanghai. Under the terms of the VIE Agreements, we have (i) the right to receive service fees on a yearly basis at an amount equivalent to all of the net profits of Management HoldCo, GDS Beijing and GDS Shanghai under the exclusive technology license and service agreements when such services are provided; (ii) the right to receive all dividends declared by Management HoldCo, GDS Beijing and GDS Shanghai and the right to all undistributed earnings of Management HoldCo, GDS Beijing and GDS Shanghai; (iii) the right to receive the residual benefits of the Management HoldCo, GDS Beijing and GDS Shanghai through its exclusive option to acquire 100% of the equity interests in Management HoldCo, GDS Beijing and GDS Shanghai, to the extent permitted under PRC law; and (iv) the right to require the shareholders of Management HoldCo, GDS Beijing, GDS Beijing’s subsidiaries and GDS Shanghai to appoint the PRC citizen (s) as designated by us to act as such shareholder’s exclusive attorney-in-fact to exercise all shareholder rights, including, but not limited to, voting on all matters of Management HoldCo, GDS Beijing, GDS Beijing’s subsidiaries and GDS Shanghai requiring shareholder approval, disposing of all or part of the shareholder’s equity interest in Management HoldCo, GDS Beijing and GDS Shanghai, and appointing directors and executive officers. During the periods presented, we provided loans to Management HoldCo, GDS Beijing and GDS Shanghai to support their working capital requirements and for capitalization purposes. In accordance with ASC 810, we have a controlling financial interest in Management HoldCo, GDS Beijing and GDS Shanghai because we have (i) the power to direct activities of Management HoldCo, GDS Beijing and GDS Shanghai that most significantly impact their economic performance; and (ii) the obligation to absorb the expected losses and the right to receive expected residual return of Management HoldCo, GDS Beijing and GDS Shanghai that could potentially be significant to Management HoldCo, GDS Beijing and GDS Shanghai. The significant judgments used and assumptions made in our determination that we are the primary beneficiary of Management HoldCo, GDS Beijing and GDS Shanghai were the terms of the VIE Agreements and our financial support to Management HoldCo, GDS Beijing and GDS Shanghai. Accordingly, we have included the financial statements of Management HoldCo, GDS Beijing and GDS Shanghai in our consolidated financial statements. Our PRC legal counsel, based on its understanding of the relevant laws and regulations, is of the opinion that each of the contracts among our wholly-owned PRC subsidiaries, our consolidated VIEs and their shareholders is valid, binding and enforceable in accordance with its terms. However, there are substantial uncertainties regarding the interpretation and application of PRC laws and future PRC laws and regulations. Any changes in PRC laws and regulations that affect our ability to control our PRC VIEs may preclude us from consolidating these companies in the future. 107 Revenue Recognition We adopted ASC 606 Revenue from Contracts with Customers on January 1, 2018. We applied ASC 606 using the cumulative effect method – i.e. by recognizing the cumulative effect of initially applying ASC 606 as an adjustment to the opening balance of accumulated deficit at January 1, 2018. We elect to apply this guidance retrospectively only to contracts that are not completed contracts as of January 1, 2018. We recognize revenue as we satisfy a performance obligation by transferring control over a good or service to a customer. For each performance obligation satisfied over time, we recognize revenue over time by measuring progress toward complete satisfaction of that performance obligation. If we do not satisfy a performance obligation over time, the performance obligation is satisfied at a point in time. Revenue is measured as the amount of consideration to which we expect to be entitled in exchange for transferring promised goods or services to a customer, excluding amounts collected on behalf of third parties. For contracts with customers that contain multiple performance obligations, we account for individual performance obligations separately if they are distinct or as a series of distinct obligations if the individual performance obligations meet the series criteria. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. The transaction price is allocated to the separate performance obligation on a relative standalone selling price basis. The standalone selling price is determined based on overall pricing objectives, taking into consideration market conditions, geographic locations and other factors. We derive revenue primarily from the delivery of colocation services and managed services, including managed hosting services and managed cloud services. The remainder of our revenue is from IT equipment sales that are either sold on a stand-alone basis or bundled in a managed hosting service contract arrangement and consulting services. Certain contracts with customers for colocation services and managed services provide for variable considerations that are primarily based on the usage of such services. Revenues on such contracts are recognized based on the agreed usage-based fees as the services are rendered throughout the contract term. Certain contracts with customers for colocation services and managed services provide for a fixed consideration over the contract service period. Revenue on such contracts are recognized on a straight-line basis over the term of the contract. In certain colocation and managed hosting service contracts, we agree to charge customers for their actual power consumption. Relevant revenue is recognized based on actual power consumption during each period. In certain other colocation and managed hosting service contracts, we specify a fixed power consumption limit each month for customers. If a customer’s actual power consumption is below the limit, no additional fee is charged, while if its actual power consumption is above the limit, we charge the customers additional power consumption fees calculated based on the portion of actual power consumption exceeding the limit, multiplied by a fixed unit price, which is determined based on market price and does not provide customers with rights to acquire additional goods or services. Accordingly, relevant revenue is recognized each month based on actual additional power consumption fees. Our colocation service and managed service contracts with customers contain both lease and nonlease components. We elected to adopt the practical expedient which allows lessors to combine lease and non-lease components and account for them as one component if i) they have the same timing and pattern of transfer; and ii) the lease component, if accounted for separately, would be classified as an operating lease. We elected to apply the practical expedient on the contracts that meet the conditions. In addition, we have performed a qualitative analysis to determine that the non-lease component is the predominant component of its revenue stream as the customer would ascribe more value to the services provided rather than to the lease component. Therefore, the combined component is accounted for in accordance with the current revenue accounting guidance (“Topic 606”). For contracts that do not meet the conditions required to adopt the practical expedient, the lease component is accounted for in accordance with the current lease accounting guidance (“Topic 842”), which is immaterial for the year ended December 31, 2019. We have elected to apply the practical expedient on a prospective basis. Revenue recognized for colocation or managed hosting and cloud services delivered prior to billing is recorded within accounts receivable. We generally bill the customer on a monthly or quarterly basis in arrears. Cash received in advance from customers prior to the delivery of the colocation or managed hosting and cloud services is recorded as deferred revenue. Revenue is generally recognized on a gross basis as we are primarily responsible for fulfilling the contract, assume inventory risk and have discretion in establishing the price when selling to the customer. To the extent we do not meet the criteria for recognizing revenue on a gross basis, we record the revenue on a net basis. 108 Leases We adopted ASC 842 using a modified retrospective transition method on all leases existing at January 1, 2019, the date of initial application. We lease a number of our data centers from third-party lessors. Each time we enter into a new lease or lease amendments, we analyze each lease or lease amendment for the proper accounting, including determining if an arrangement is or contains a lease at inception and making assessment of the leased properties to determine if they are operating or finance leases. Determination of accounting treatment, including the result of the lease classification test for each new lease or lease amendment, is dependent on a variety of judgments, such as identification of lease and non-lease components, allocation of total consideration between lease and non-lease components, determination of lease term, assessing the valuation of leased property and establishing the incremental borrowing rate to calculate the present value of the minimum lease payment for the lease test. The judgments used in the accounting for leases are inherently subjective. Different assumptions or estimates could result in different accounting treatment for a lease. Impairment of Goodwill Goodwill is an asset representing the future economic benefits arising from other assets acquired in the acquisition that are not individually identified and separately recognized. Goodwill is not amortized but is tested for impairment annually or more frequently if events or changes in circumstances indicate that it might be impaired. Goodwill is tested for impairment at the reporting unit level on an annual basis and between annual tests if an event occurs or circumstances change that would more-likely-than-not reduce the fair value of a reporting unit below its carrying value. These events or circumstances could include a significant change in the stock prices, business climate, legal factors, operating performance indicators, competition, or sale or disposition of a significant portion of a reporting unit. Application of the goodwill impairment test requires judgment, including the identification of the reporting unit, assignment of assets and liabilities to the reporting unit, assignment of goodwill to the reporting unit, and determination of the fair value of each reporting unit. We have the option to perform a qualitative assessment to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying value prior to performing the two-step goodwill impairment test. If it is more-likely-than-not that the fair value of a reporting unit is greater than its carrying amount, the two-step goodwill impairment test is not required. If the two- step goodwill impairment test is required, first, the fair value of the reporting unit is compared with its carrying amount (including goodwill). If the fair value of the reporting unit is less than its carrying amount, an indication of goodwill impairment exists for the reporting unit and we perform step two of the impairment test (measurement). Under step two, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation and the residual fair value after this allocation is the implied fair value of the reporting unit goodwill. Impairment of Long-Lived Assets Long-lived assets (primary including property and equipment, operating lease right-of-use assets and prepaid land use rights) are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, we first compare undiscounted cash flows expected to be generated by that asset or asset group to its carrying amount. If the carrying amount of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying amount exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary. Share-based Compensation We adopted an equity incentive plan in July 2014, or the 2014 share incentive plan, for the granting of share options to key employees, directors and external consultants in exchange for their services. The total number of shares that may be issued under the 2014 share incentive plan is 29,240,000 ordinary shares. 109 We adopted a second equity incentive plan in August 2016, or the 2016 share incentive plan, for the granting of share options and other equity awards to key employees and directors in exchange for their services. The maximum aggregate number of shares which may be subject to equity awards under the 2016 share incentive plan is 56,707,560 shares, provided, however, that such maximum aggregate number of shares shall be automatically increased on the first day of each fiscal year (i.e., January 1 of each calendar year) during which the 2016 share incentive plan remains in effect to three percent (3%) of our then total issued and outstanding shares, if and whenever the shares which may be subject to equity awards under the 2016 share incentive plan accounts for less than one and half percent (1.5%) of our then total issued and outstanding shares. Restricted shares to directors, officers and employees In July 2017, August 2018 and August 2019, we granted 13,475,060, 12,941,952 and 14,314,160 non-vested restricted shares, respectively, to employees, officers and directors. The restricted share awards were granted subject to service and market conditions, or service and performance conditions, which are tied to our financial performance. For restricted shares granted, the value of the restricted shares was determined by the fair value of the restricted shares on the grant date, on which all criteria for establishing the grant dates were satisfied. The value of restricted shares subject to service conditions and market conditions attached is recognized as a compensation expense using the graded-vesting method. The value of restricted shares subject to performance conditions attached is recognized as a compensation expense using the graded-vesting method only when achievement of the performance conditions becomes probable. For restricted shares with market conditions, the probability to achieve market conditions is reflected in the grant date fair value. A summary of the restricted share activity is as follows: Unvested at January 1, 2017 Granted Vested Forfeited Unvested at December 31, 2017 Granted Vested Forfeited Unvested at December 31, 2018 Granted Vested Forfeited Unvested at December 31, 2019 Number of Shares 12,910,080 13,977,060 (2,123,120) (238,400) 24,525,620 13,202,512 (7,326,620) (891,008) 29,510,504 14,551,472 (9,122,432) (1,582,248) 33,357,296 We recognized restricted share related share-based compensation expenses of RMB56.2 million, RMB89.8 million and RMB189.4 million (US$27.2 million) for the years ended December 31, 2017, 2018 and 2019, respectively. As of December 31, 2019, total unrecognized compensation expense relating to the unvested shares was RMB360.5 million (US$51.8 million). The expense is expected to be recognized over a weighted average period of 1.77 years using the graded-vesting attribution method. We did not capitalize any of the share-based compensation expenses as part of the cost of any asset for the years ended December 31, 2017, 2018 and 2019. The fair value of the restricted shares granted is estimated on the date of grant using the Monte Carlo simulation model with the following assumptions used. Grant date: Risk-free rate of return Volatility Expected dividend yield Share price at grant date Expected term 110 August 2018 August 2019 20.43~21.48 % July 2017 1.29~1.63 % 2.047% ~ 2.418 % 1.67% - 1.88 % 63.22 % — US$3.125 US$5.02375 (RMB34.6) 1~3 years — US$1.191 (RMB8.0) 2~4 years (RMB21.3) 1~3 years 71.85 % — (1) Volatility Expected volatility is assumed based on the historical volatility of our comparable companies or our historical volatility in the period equal to the expected term of each grant. (2) Risk-free interest rate Risk-free rate equal to the United States Government Treasury Yield Rates for a term equal to the remaining expected term. (3) Dividend yield We estimated the dividend yield based on our expected dividend policy over the expected terms of the restricted shares. Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for deferred tax assets for which it is more likely than not that the related tax benefits will not be realized. We recognize the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. We record interest related to unrecognized tax benefits in interest expense and penalties in general and administrative expenses. Uncertainties exist with respect to how the current income tax law in the PRC applies to our overall operations, and more specifically, with regard to tax residency status. The Enterprise Income Tax Law includes a provision specifying that legal entities organized outside the PRC are considered residents for Chinese income tax purposes if the place of effective management or control is within the PRC. The implementation rules to the Enterprise Income Tax Law provide that non-resident legal entities are considered PRC residents if substantial and overall management and control over the manufacturing and business operations, personnel, accounting, properties, etc., occurs within the PRC. Despite the present uncertainties resulting from the limited PRC tax guidance on the issue, we do not believe that the legal entities organized outside the PRC should be treated as residents for Enterprise Income Tax Law purposes. If the PRC tax authorities subsequently determine that we and our subsidiaries registered outside the PRC are deemed resident enterprises, we and our subsidiaries registered outside the PRC will be subject to the PRC income tax at a rate of 25%. If we were to be non-resident for PRC tax purposes, dividends paid to us from profits earned by the PRC subsidiaries after January 1, 2008 would be subject to a withholding tax. The Enterprise Income Tax Law and its relevant regulations impose a withholding tax at 10%, unless reduced by a tax treaty or agreement, for dividends distributed by a PRC-resident enterprise to its non- PRC-resident corporate investor for earnings generated beginning on January 1, 2008. Undistributed earnings generated prior to January 1, 2008 are exempt from such withholding tax. We have not recognized any deferred tax liability for the undistributed earnings of the PRC-resident enterprise as of December 31, 2017, 2018 and 2019, as we plan to permanently reinvest these earnings in the PRC. See “Item 3. Key Information—D. Risk Factors—Risks Related to Doing Business in the People’s Republic of China— Dividends payable to our foreign investors and gains on the sale of our ADSs or Class A ordinary shares by our foreign investors may become subject to PRC tax” and “—We and our shareholders face uncertainties with respect to indirect transfers of equity interests in PRC resident enterprises or other assets attributed to a Chinese establishment of a non-Chinese company, or immovable properties located in China owned by non-Chinese companies.” Recently Issued Accounting Standards In December 2019, the FASB issued Accounting Standards Update (“ASU”) 2019-12, Income Tax (Topic 740), Simplifying the Accounting for Income Taxes, which simplifies accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The ASU also improves consistent application of and simplifies GAAP for other areas of Topic 740 by clarifying and amending existing guidance. For public entities, the ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted including adoption in any interim period for periods for which financial statements have not yet been issued. We are currently evaluating the impact the adoption of this standard will have on our consolidated financial statements. 111 In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350- 40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force), which clarifies the accounting for implementation costs incurred in a hosting arrangement that is a service contract. Capitalization of these implementation costs are accounted for under the same guidance as implementation costs incurred to develop or obtain internal-use software and recorded as a prepaid asset. These capitalized costs are to be expensed ratably over the hosting arrangement term as an operating expense, along with the service fees. The guidance is effective for periods beginning after December 15, 2019. Early adoption is allowed. We do not plan to early adopt this guidance and the adoption of this standard is not expected to have a significant impact on our consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which changes the fair value measurement disclosure requirements of ASC 820. Under this ASU, key provisions include new, eliminated and modified disclosure requirements. The guidance is effective for periods beginning after December 15, 2019. Early adoption is allowed. We do not plan to early adopt this guidance and the adoption of this standard is not expected to have a significant impact on our consolidated financial statements. In January 2017, FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU simplifies the subsequent measurement of goodwill. The ASU eliminates step 2 from the goodwill impairment test and the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This ASU should be applied on a prospective basis. The amendments in this ASU are effective for us for our annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We do not plan to early adopt this guidance and the adoption of this standard is not expected to have a significant impact on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments, and issued subsequent amendments to the initial guidance within ASU 2018-19, ASU 2019-04, ASU 2019-05, ASU 2019-11 and ASU 2020-02, collectively referred to as “ASC 326”. ASC 326 requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. This ASU eliminates the probable initial recognition threshold in current GAAP and, instead, reflects an entity’s current estimate of all expected credit losses. ASC 326 is effective for us for our fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We will adopt ASC 326 on January 1, 2020. The adoption of this standard will result in a change of our provision policy primarily for accounts receivable, but is not expected to have a significant impact on our consolidated financial statements. 112 A. Results of Operations Selected Consolidated Financial Information The following table sets forth a summary of our consolidated results of operations for the years ended December 31, 2017, 2018 and 2019. This information should be read together with our audited consolidated financial statements as of December 31, 2018 and 2019 and for the years ended December 31, 2017, 2018 and 2019 and related notes included elsewhere in this annual report on Form 20-F.

After the acquisition, this target company had a net revenue of nil and a net loss of RMB8.8 million (US$1.3 million) from October 19, 2019 to December 31, 2019, which is included in our results of operations for the year ended December 31, 2019. Contingent consideration payables of RMB241.7 million (US$34.7 million) were outstanding as of December 31, 2019. Year Ended December 31, 2019 Compared to Year Ended December 31, 2018 Net Revenue Our net revenue increased by 47.6% to RMB4,122.4 million (US$592.1 million) in 2019 from RMB2,792.1 million in 2018. This increase was due to increases in service revenue of RMB1,335.1 million, partially offset by the decrease in IT equipment sales of RMB4.8 million. The increase in service revenue consisted of an increase in revenue from colocation services of RMB1,157.5 million and an increase in revenue from managed services and other services of RMB177.6 million. These increases in service revenue were mainly due to (i) an increase in area utilized from 108,326 sqm as of December 31, 2018 to 156,022 sqm as of December 31, 2019, as customers with commitments moved into the data center area, (ii) the signing of new service contracts by customers who commenced utilizing services during the period, (iii) the commencement of operations of new data centers since December 31, 2018 and (iv) the acquisition of two data centers in Guangzhou and Shanghai in 2018, and of a data center in Guangzhou in 2019, respectively. 113 Cost of Revenue Our cost of revenue increased by 41.9% to RMB3,079.7 million (US$442.4 million) in 2019 from RMB2,169.6 million in 2018. This increase was primarily due to an increase of 40.6% in utility costs to RMB922.8 million (US$132.6 million) in 2019 from RMB656.1 million in 2018, and an increase of 57.5% in depreciation and amortization costs to RMB1,071.7 million (US$153.9 million) in 2019 from RMB680.3 million in 2018. Increases in both utility costs and depreciation and amortization costs were largely a result of an increase in new data center facilities. In addition, the increase in cost of revenue was also due to (i) an increase in personnel costs of RMB47.9 million in connection with more data centers coming into service, (ii) an increase of RMB30.6 million in rental expense for operating lease and service fees for third-party data centers, (iii) an increase of RMB28.0 million for share-based compensation expenses, (iv) an increase of RMB19.5 million for network cost and (v) an increase of RMB126.0 million for maintenance and other costs. Cost of revenue as percentage of net revenue decreased to 74.7% in 2019 from 77.7% in 2018. Operating Expenses Our total operating expenses increased by 24.0% to RMB562.9 million (US$80.9 million) in 2019 as compared to RMB454.1 million in 2018. The increase was primary due to an increase in share-based compensation expenses of RMB55.9 million, personnel cost of RMB16.4 million, depreciation and amortization expenses of RMB9.1 million and office and travelling expenses of RMB7.5 million. Our total operating expenses as a percentage of our net revenue decreased to 13.7% in 2019 from 16.3% in 2018. Selling and Marketing Expenses. Our selling and marketing expenses increased by 17.5% to RMB129.9 million (US$18.7 million) in 2019 from RMB110.6 million in 2018. This increase was primarily attributable to (i) an increase in share-based compensation expenses of RMB14.2 million and (ii) an increase in personnel costs of RMB4.4 million, related to bonuses and the hiring of sales personnel. General and Administrative Expenses. Our general and administrative expenses increased by 24.8% to RMB411.4 million (US$59.1 million) in 2019 from RMB329.6 million in 2018. This increase was primarily a result of (i) an increase in share-based compensation expenses of RMB40.2 million, (ii) an increase in personnel costs of RMB8.7 million, (iii) an increase in depreciation and amortization expenses of RMB8.4 million and (iv) an increase in office and travelling expenses of RMB7.2 million due to the expansion of our business. Research and Development Expenses. Our research and development expenses increased by 55.4% to RMB21.6 million (US$3.1 million) in 2019 from RMB13.9 million in 2018, which was primarily due to an increase in research and development projects to enhance our existing operations. Other Income (Expenses) Interest Income. Our interest income increased by 175.9% to RMB53.0 million (US$7.6 million) in 2019 from RMB19.2 million in 2018. The increase was primarily a result of an increase in cash balance raised from our public offering and issuance of preferred shares. Interest Expenses. Our interest expenses increased by 47.6% to RMB968.7 million (US$139.1 million) in 2019 from RMB656.2 million in 2018. This increase was primarily a result of an increase of borrowings, finance lease and other financing obligations and convertible bonds payable. Government Grants. Income from government grants increased by 207.7% to RMB9.9 million (US$1.4 million) in 2019 from RMB3.2 million in 2018, primarily due to the additional deduction of input value-added tax. Foreign Currency Exchange Gain (Loss), net. Changes in currency rates resulted in a loss of RMB6.0 million (US$0.9 million) in 2019 as compared to a gain of RMB20.3 million in 2018, primarily due to the appreciation of the U.S. dollar relative to Renminbi. Income Tax Benefits (Expenses). Income tax expenses were RMB15.7 million (US$2.2 million) in 2019, compared to the income tax benefits of RMB9.4 million in 2018. The income tax expenses in 2019 were primarily due to the profit generated in certain of our subsidiaries as a result of increase in utilization in the related data centers. 114 Net Loss. As a result of the foregoing, net loss increased to RMB442.1 million (US$63.5 million) in 2019 from RMB430.3 million in 2018. Year Ended December 31, 2018 Compared to Year Ended December 31, 2017 Net Revenue Our net revenue increased by 72.8% to RMB2,792.1 million in 2018 from RMB1,616.2 million in 2017. This increase was due to increases in service revenue and IT equipment sales of RMB1,167.6 million and RMB8.3 million, respectively. The increase in service revenue consisted of an increase in revenue from colocation services of RMB885.1 million, an increase in revenue from managed services of RMB274.9 million and an increase in revenue from consulting services of RMB7.6 million. These increases in service revenue were mainly due to (i) an increase in area utilized from 61,713 sqm as of December 31, 2017 to 108,326 sqm as of December 31, 2018, as customers with commitments moved into the data center area, (ii) the signing of new service contracts by customers who commenced utilizing services during the period, (iii) the commencement of operations of new data centers since December 31, 2017 and (iv) the acquisition of two data centers in Shenzhen and Guangzhou in 2017, and two data centers in Guangzhou and Shanghai in 2018, respectively. Cost of Revenue Our cost of revenue increased by 79.7% to RMB2,169.6 million in 2018 from RMB1,207.7 million in 2017. This increase was primarily due to an increase of 80.6% in utility costs to RMB656.1 million in 2018 from RMB363.3 million in 2017, and an increase of 97.0% in depreciation and amortization costs to RMB680.3 million in 2018 from RMB345.4 million in 2017. Increases in both utility costs and depreciation and amortization costs were largely a result of an increase in new data center facilities. In addition, the increase in cost of revenue was also due to (i) an increase of RMB66.0 million in rental expense for operating lease and service fees for third-party data centers, (ii) an increase in personnel costs of RMB36.8 million in connection with more data centers coming into service, (iii) an increase of RMB13.1 million for network cost, (iv) an increase of RMB8.0 million for cost of equipment sold and (v) an increase of RMB210.3 million for maintenance and other costs. Cost of revenue as percentage of net revenue increased to 77.7% in 2018 from 74.7% in 2017. Operating Expenses Our total operating expenses increased by 39.2% to RMB454.1 million in 2018 as compared to RMB326.2 million in 2017. The increase was primary due to an increase in share-based compensation expenses of RMB38.0 million, personnel cost of RMB28.2 million, depreciation and amortization expenses of RMB28.4 million and professional service fees of RMB11.8 million. Our total operating expenses as a percentage of our net revenue decreased to 16.3% in 2018 from 20.2% in 2017. Selling and Marketing Expenses. Our selling and marketing expenses increased by 22.7% to RMB110.6 million in 2018 from RMB90.1 million in 2017. This increase was primarily attributable to (i) an increase in personnel costs of RMB13.3 million, related to bonuses and the hiring of sales personnel, and (ii) an increase in share-based compensation expenses of RMB6.8 million. General and Administrative Expenses. Our general and administrative expenses increased by 44.0% to RMB329.6 million in 2018 from RMB228.9 million in 2017. This increase was primarily a result of (i) an increase in share-based compensation expenses of RMB30.8 million, (ii) an increase in depreciation and amortization expenses of RMB28.4 million, (iii) an increase in personnel costs of RMB14.0 million and (iv) an increase in professional service fees of RMB11.8 million due to the expansion of our business. Research and Development Expenses. Our research and development expenses increased by 91.6% to RMB13.9 million in 2018 from RMB7.3 million in 2017, which was primarily due to an increase in research and development projects to enhance our existing operations. Other Income (Expenses) Interest Income. Our interest income increased by 243.1% to RMB19.2 million in 2018 from RMB5.6 million in 2017. The increase was primarily a result of an increase in cash balance raised from our public offering and issuance of convertible bonds. 115 Interest Expenses. Our interest expenses increased by 59.3% to RMB656.2 million in 2018 from RMB412.0 million in 2017. This increase was primarily a result of an increase of borrowings, finance lease and other financing obligations and convertible bonds payable. Government Grants. Income from government grants increased by 5.1% to RMB3.2 million in 2018 from RMB3.1 million in 2017. Foreign Currency Exchange Gain (Loss), net. Changes in currency rates resulted in a gain of RMB20.3 million in 2018 as compared to a loss of RMB12.3 million in 2017, primarily due to the appreciation of the U.S. dollar relative to Renminbi. Income Tax Benefits (Expenses). Income tax benefits increased to RMB9.4 million in 2018 from RMB6.1 million in 2017. This increase was primarily due to the realization of deferred tax liabilities arising from acquisitions. Net Loss. As a result of the foregoing, net loss increased to RMB430.3 million in 2018 from RMB326.9 million in 2017. B. Liquidity and Capital Resources Our primary sources of liquidity have been cash flow from short-term and long-term borrowings, including borrowings from related parties, and issuance of debt and equity securities, including in our initial public offering, follow-on public offering, private placement and convertible bonds, which have historically been sufficient to meet our working capital and substantially all of our capital expenditure requirements. Historically, we also have had finance lease and other financing obligations. As of December 31, 2019, we had cash of RMB5,810.9 million (US$834.7 million). In addition, as of December 31, 2019, total short-term debt was RMB1,360.2 million (US$195.4 million), comprised of short-term borrowings and the current portion of long-term borrowings of RMB1,137.7 million (US$163.4 million) and the current portion of finance lease and other financing obligations of RMB222.5 million (US$32.0 million). As of the same date, total long-term debt was RMB14,829.3 million (US$2,130.0 million), comprised of long-term borrowings (excluding current portion) of RMB8,028.5 million (US$1,153.2 million), the non-current portion of finance lease and other financing obligations of RMB4,751.1 million (US$682.4 million) and convertible bonds payable of RMB2,049.7 million (US$294.4 million). Based on our current level of operations and available cash, including the proceeds we received from our initial public offering, follow-on public offerings, private placement and offering of convertible bonds, we believe our available cash, cash flows from operations, will provide sufficient liquidity to fund our current obligations, projected working capital requirements, debt service requirements and capital spending requirements at least for the next 12 months. However, we may require additional cash resources due to changing business conditions or other future developments, including any investments or acquisitions we may decide to selectively pursue. If our existing cash resources are insufficient to meet our requirements, we may seek to sell equity or equity-linked securities, debt securities or borrow from banks. We cannot assure you that financing will be available in the amounts we need or on terms acceptable to us, if at all. The sale of additional equity securities, including convertible debt securities, would result in additional dilution to our shareholders. The incurrence of indebtedness and issuance of debt securities would result in debt service obligations and could result in operating and financial covenants that restrict our operations and our ability to pay dividends to our shareholders. If we were unable to obtain additional equity or debt financing as required, our business, operations and prospects and our ability to maintain our desired level of revenue growth may suffer materially. As a holding company with no material operations of our own, we are a corporation separate and apart from our subsidiaries and our consolidated VIEs and, therefore, provide for our own liquidity. We conduct our operations primarily through our PRC subsidiaries in China. As a result, our ability to pay dividends and to finance any debt we may incur depends upon dividends paid by our subsidiaries. If our PRC subsidiaries, or any newly formed PRC subsidiaries, incur debt on their own behalf in the future, the instruments governing their debt may restrict their ability to pay dividends to us. In addition, our PRC subsidiaries are permitted to pay dividends to us only out of their respective retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. Under applicable PRC laws and regulations, our PRC subsidiaries are each required to set aside a portion of their after-tax profits each year to fund certain statutory reserves, and funds from such reserves may not be distributed to us as cash dividends except in the event of liquidation of such subsidiaries. 116 The PRC government imposes controls on the convertibility of the RMB into foreign currencies and, in certain cases, the remittance of currency out of China. We receive substantially all of our revenues in RMB. Under our current corporate structure, our company in the Cayman Islands may rely on dividend payments from our PRC subsidiaries to fund any of our cash and financing requirements. Under China’s existing foreign exchange regulations, our PRC subsidiaries are able to make payments of current accounts, such as dividends, to their offshore holding companies, in foreign currencies, without prior approval from SAFE, by complying with certain procedural requirements. However, approval from appropriate government authorities will be required where RMB is to be converted into foreign currency and remitted out of China to pay capital expenses such as the repayment of loans denominated in foreign currencies. There is no requirement imposed on investors to complete registration or obtain approval from appropriate government authorities before they can receive dividend payments from our company in the Cayman Islands. See “Item 3. Key Information—D. Risk Factors—Risks Related to Doing Business in the People’s Republic of China—Restrictions on currency exchange may limit our ability to utilize our net revenue effectively.” These statutory limitations affect, and future covenant debt limitations might affect, our PRC subsidiaries’ ability to pay dividends to us. As of December 31, 2019, our cash and restricted cash were deposited in major financial institutions located in PRC, Hong Kong, United States and Singapore. We currently believe that such limitations will not impact our ability to meet our ongoing short- term cash obligations although we cannot assure you that such limitations will not affect our ability in the future to meet our short- term cash obligations and to distribute dividends to our shareholders. See “Item 3. Key Information—D. Risk Factors—Risks Related to Doing Business in the People’s Republic of China—We rely to a significant extent on dividends and other distributions on equity paid by our principal operating subsidiaries to fund offshore cash and financing requirements” and “—Statutory Reserves.” We do not plan for our PRC subsidiaries to pay dividends in the foreseeable future and we intend for those subsidiaries to retain any future earnings for use in the operation and expansion of our business in China. Accordingly, our ability to pay dividends and finance debt will be affected by this current plan. In the future, we may take advantage of financing options available to us in connection with any dividend payments we may make or repayments of any offshore indebtedness we may incur. For example, we may fund dividend payments through offshore debt, whether unsecured or secured by the assets of our onshore consolidated entities. In order to service offshore debt, we may rely upon financing options through the capital markets, including issuances of equity or debt securities, the proceeds of which we may use to service offshore debt. Pursuant to the PRC Enterprise Income Tax Law, a withholding tax rate of 10% currently applies to dividends paid by a PRC “resident enterprise” to a foreign enterprise investor, unless any such foreign investor’s jurisdiction of incorporation has a tax treaty with China that provides for preferential tax treatment. Accordingly, if in the future our PRC subsidiaries that are considered “resident enterprises” pay dividends to the Hong Kong subsidiary that holds such PRC subsidiary, any such dividend may be subject to a withholding tax of 10%. Such withholding tax rate may be lowered to 5% if a Hong Kong resident enterprise owns no less than 25% of a PRC enterprise. However, the 5% withholding tax rate does not automatically apply and certain requirements must be satisfied. See “Item 3. Key Information—D. Risk Factors—Risks Related to Doing Business in the People’s Republic of China—We may not be able to obtain certain benefits under the relevant tax treaty on dividends paid by our PRC subsidiaries to us through our Hong Kong subsidiary.” As a result of these laws, rules and regulations relating to statutory reserves, foreign exchange conversion and withholding taxes described above, our subsidiaries incorporated in China are restricted in their ability to transfer a portion of their respective net assets to their offshore holding companies as dividends, loans or advances. As of December 31, 2019, we had restricted net assets of RMB7,367.5 million (US$1,058.3 million), which mainly consisted of paid-in registered capital. 117 The following table sets forth a summary of our cash flows for the years indicated.

Net cash used in investing activities was RMB4,733.1 million in 2018, which was primarily due to the payments for purchase of property and equipment and land use rights of RMB4,258.0 million for the development of our data centers, including the deposit paid and net of the proceeds from disposal of property and equipment, and payments for acquisitions of RMB475.1 million. Net cash used in investing activities was RMB2,005.1 million in 2017, which was primarily due to the deposits and payments for purchase of property and equipment of RMB1,760.2 million for the development of our data centers, including the deposit paid, and payments related to acquisitions of RMB244.9 million. Financing Activities Net cash provided by financing activities was RMB8,361.9 million (US$1,201.1 million) in 2019, which was primarily due to proceeds from borrowings, net of issuance cost, of RMB5,311.5 million (US$763.0 million), net proceeds from issuance of ordinary shares of RMB4,934.1 million (US$708.7 million), net proceeds from issuance of redeemable preferred shares of RMB989.3 million (US$142.1 million), proceeds from a financial institution of RMB302.8 million (US$43.5 million), partially offset by repayment of short-term and long-term borrowings of RMB2,727.9 million (US$391.8 million), payment under finance lease and other financing obligations of RMB289.5 million (US$41.6 million) and payment of contingent consideration for acquisitions of RMB120.1 million (US$17.2 million).

Statutory Reserves Under applicable PRC laws and regulations, foreign-invested enterprises in China are required to provide for certain statutory reserves, namely a general reserve, an enterprise expansion fund and a staff welfare and bonus fund. Pursuant to such laws and regulations, we may pay dividends only out of our after-tax profits, if any, determined in accordance with PRC accounting standards and regulations. Further, we are required to allocate at least 10% of our after-tax profits to fund the general reserve until such reserve has reached 50% of our registered capital. In addition, we may also set aside, at our or our Board’s discretion, a portion of our after- tax profits to fund the employee welfare and bonus fund. These reserves may only be used for specific purposes and are not distributable to us in the form of loans, advances, or cash dividends. As of December 31, 2018 and 2019, we had RMB0.6 million and RMB15.7 million (US$2.3 million), respectively, in our statutory reserves. Capital Expenditures We had capital expenditures, excluding payments related to acquisitions, of RMB1,760.2 million, RMB4,258.0 million and RMB4,552.6 million (US$654.0 million)in 2017, 2018 and 2019, respectively. Our capital expenditures were primarily for the purchase of equipment, prepaid land use rights reported in investing activities in the Consolidated Financial Statements and leasehold- improvement of data centers. Our capital expenditures have been primarily funded by net cash provided by financing activities. 119 Project Financing Structure Our data center projects are financed with both equity and debt. We typically capitalize a portion of our data center project’s funding requirement with proceeds raised from financing offshore that is injected into China as registered capital through each of our data center project-specific legal entities. Under SAFE and PRC regulations, registered capital for each legal entity can only be used for its own business use or project-designated purposes, which also follows under its registered business scope. Once the registered capital is injected into China, it is often difficult to remit the proceeds back offshore or to lend it to our other onshore subsidiaries. Thus, we inject registered capital only as needed throughout the development phase of the data center project to remain flexible with our offshore capital. Concurrently, we capitalize each data center project through onshore project-specific loan facilities from banking or other financial institutions in China to finance the remaining capital required in completing the data center project. Under this arrangement, each data center’s estimated cash flows are matched and committed to service its own debt obligations during the term of its loan facilities. In conjunction with the registered capital injected, we sometimes inject a portion of our offshore capital to our onshore project entities through shareholder’s loans. In these instances, we utilize the shareholder’s loans as a temporary bridge to capitalize our projects until project-specific loan facilities have been obtained. Once the project loans are in place, subject to the agreement by lending bank(s), the shareholder’s loans are repaid back offshore. Convertible Bonds and Convertible Notes On November 17, 2017, the full principal amount of the outstanding US$150.0 million convertible bonds was voluntarily converted into ordinary shares by Ping An Insurance and STT GDC at a set conversion price of US$1.675262 per ordinary share, or US$13.40 per ADS. Upon conversion of the principal amount of and interest accrued on the convertible bonds, we issued approximately 97.9 million additional Class A ordinary shares, representing 10.4% of our enlarged issued share capital. On June 5, 2018, we issued and sold convertible senior notes due in 2025 in an aggregate principal amount of US$300 million, which notes bear interest at a rate of 2% per year, payable on June 1 and December 1 of each year, beginning on December 1, 2018. The convertible senior notes will mature on June 1, 2025, unless earlier redeemed, repurchased or converted in accordance with their terms. The convertible senior notes may be converted into our ADSs, at the option of the holders, at an initial conversion rate of 19.3865 of our ADSs per US$1,000 principal amount of notes, or approximately 5,815,950 ADSs, representing 46,527,600 Class A ordinary shares, assuming conversion of the entire US$300 million aggregate principal amount at the initial conversion rate. Convertible Preferred Shares In March 2019, Ping An Overseas Holdings made an investment in us, and we issued 150,000 Series A convertible preferred shares to an affiliate of Ping An Overseas Holdings for a total consideration of US$150 million. Pursuant to the terms of the investment, during the first eight years from their issuance date, the convertible preferred shares accrue a minimum 5.0% per annum dividend, payable quarterly in arrears, in cash or in kind in the form of additional convertible preferred shares, at our option. As of the eighth anniversary of the issuance date, the convertible preferred shares accrue a 7.0% per annum minimum dividend, payable quarterly in arrears, in cash only, which dividend rate will further increase by 50 basis points per quarter thereafter for so long as any convertible preferred shares remain outstanding. The convertible preferred shares are convertible into our Class A ordinary shares at the option of their holder, at a conversion rate corresponding to a conversion price of US$35.60 per ADSs, representing a premium of 13.3% to the volume weighted average price of our ADSs for the 30 trading days immediately preceding the date of signing the definitive agreement, subject to customary anti-dilution adjustments. We have the right to trigger a mandatory conversion at our election, beginning on March 15, 2022, provided certain conditions are met, including our Class A ordinary shares achieving a specified price threshold of 150% of the conversion price for a specified period. Holders will not have any redemption right or put option over the convertible preferred shares, except upon (i) the occurrence of a change of control, or (ii) our ADSs ceasing to be listed for trading on any of the New York Stock Exchange, the Nasdaq Global Select Market or the Nasdaq Global Market. After eight years, we will have certain rights in connection with the redemption of the convertible preference shares at 100% of their face value, plus accrued and unpaid dividends. In addition, Ping An Overseas Holdings has the right to designate one non-voting observer to attend any meetings of our board of directors, subject to maintaining its shareholding at or above a specified percentage threshold. 120 Loans and borrowings As of December 31, 2018 and 2019, we had short-term borrowings of RMB684.8 million with weighted average interest rate of 7.01%, and RMB397.2 million (US$57.1 million) with weighted average interest rate of 5.64%, respectively, and long-term borrowings (including current portion) of RMB5,802.2 million with weighted average interest rate of 7.42%, and RMB8,769.0 million (US$1,259.6 million) with weighted average interest rate of 7.40%, respectively, taking into consideration of debt issuance costs relating to the facilities. Our company, through one or more of our subsidiaries, entered into secured and unsecured loan agreements with various financial institutions for project development and working capital purpose with terms ranging from one to 13 years. More specifically, the terms of these secured loan facility agreements generally include one or more of the following conditions. If any of the below conditions were to be triggered, we could be obligated to notify the lender or repay any loans outstanding immediately or on an accelerated repayment schedule. See “Item 3.

We did not pay any other cash compensation or benefits in kind to our directors and executive officers. We set aside an aggregate of US$0.1 million for pensions, retirement or other benefits for our directors and executive officers in 2019. For information regarding options granted to our directors and executive officers, see “—Share Incentive Plans.” Share Incentive Plans 2014 Share Incentive Plan Our equity incentive plan adopted in 2014, or the 2014 share incentive plan, provides for the grant of options, share appreciation rights or other share-based awards, which we refer to collectively as equity awards. Up to 29,240,000 ordinary shares upon exercise of equity awards may be granted under the 2014 share incentive plan. We believe that the plan will aid us in recruiting, retaining and motivating key employees, directors and consultants of outstanding ability through the granting of equity awards. Administration The 2014 share incentive plan is administered by our board of directors (only with respect to options granted on the date of the completion of our initial public offering), the remuneration committee, or any subcommittee thereof to whom the board or the remuneration committee shall delegate the authority to grant or amend equity awards. The plan administrator is authorized to interpret the plan, to establish, amend and rescind any rules and regulations relating to the plan, and to make any other determinations that it deems necessary or desirable for the administration of the plan, as well as determine the provisions, terms and conditions of each award consistent with the provisions of the plan. 130 Change in Control In the event of a change in control, any outstanding awards that are unexercisable or otherwise unvested or subject to lapse restrictions, as determined by the plan administrator, will automatically be deemed exercisable or otherwise vested or no longer subject to lapse restrictions, as the case may be, immediately prior to such change in control. The plan administrator may also, in its sole discretion, decide to cancel such awards for fair value, provide for the issuance of substitute awards that will substantially preserve the otherwise applicable terms of any affected awards previously granted or provide that affected options will be exercisable for a period of at least 15 days prior to the change in control but not thereafter. A “change in control” under the 2014 share incentive plan is defined as (i) the sale of all or substantially all of our assets, (ii) any person or group (other than certain permitted holders) becomes the beneficial owner of more than 50% of the total voting power of our voting stock or (iii) a majority of our board of directors ceases to be continuing directors during any period of two consecutive years. Term Unless terminated earlier, the 2014 share incentive plan will continue in effect for a term of five years from the date of its adoption. Vesting Schedule In general, the plan administrator determines, or the award agreement specifies, the vesting schedule. Amendment and Termination of Plan Our board of directors may at any time amend, alter or discontinue the 2014 share incentive plan, subject to certain exceptions. Granted Options The total number of shares that may be issued under the 2014 share incentive plan is 29,240,000. As of the date of this annual report, options to purchase 14,621,096 ordinary shares were fully vested and outstanding. The table below summarizes, as of the date of this annual report, the options we have granted to our directors and executive officers.

(1) Note: Fully vested. As of the date of this annual report, individuals other than our directors and executive officers as a group held options to purchase a total of 1,698,000 ordinary shares of our company, with an exercise price of US$0.7792 per ordinary share. 131 2016 Share Incentive Plan Our second equity incentive plan adopted in 2016, or the 2016 share incentive plan, provides for the grant of share options, share appreciation rights, restricted share units, restricted shares or other share-based awards, which we refer to collectively as equity awards. We believe that the 2016 share incentive plan will aid us in recruiting, retaining and motivating key employees and directors of outstanding ability through the granting of equity awards. The maximum aggregate number of shares which may be subject to equity awards under the 2016 share incentive plan is 56,707,560 shares, provided, however, that such maximum aggregate number of shares shall be automatically increased on the first day of each fiscal year (i.e., January 1 of each calendar year) during which the 2016 share incentive plan remains in effect to three percent (3%) of our then total issued and outstanding shares, if and whenever the shares which may be subject to equity awards under the 2016 share incentive plan accounts for less than one and half percent (1.5%) of our then total issued and outstanding shares. Administration The 2016 share incentive plan is administered by our board of directors (only with respect to equity awards granted on the date of the completion of our initial public offering), the remuneration committee, or any subcommittee thereof to whom the board or the remuneration committee shall delegate the authority to grant or amend equity awards. The plan administrator is authorized to interpret the plan, to establish, amend and rescind any rules and regulations relating to the plan, and to make any other determinations that it deems necessary or desirable for the administration of the plan, as well as determine the provisions, terms and conditions of each award consistent with the provisions of the plan. Change in Control In the event of a change in control (as defined below), if determined by the plan administrator in an award agreement or otherwise, any outstanding equity awards that are non-exercisable or otherwise unvested or subject to lapse restrictions, will automatically be deemed exercisable or otherwise vested or no longer subject to lapse restrictions, as the case may be, immediately prior to such change in control. The plan administrator may also, in its sole discretion, decide to cancel such equity awards for fair value, provide for the issuance of substitute awards that will substantially preserve the otherwise applicable terms of any affected awards previously granted or provide that affected share options or share appreciation rights will be exercisable for a period of at least 15 days prior to the change in control and terminated upon the change in control if not previously exercised. A “change in control” under the 2016 share incentive plan is generally defined as (i) the sale of all or substantially all of our assets to any person or group (other than certain permitted holders), unless the primary purpose of the sale is to create a holding entity for us that will be directly or indirectly owned in substantially the same proportions by the same persons that held our shares immediately prior to the consummation of such sale, or (ii) one or more related transactions whereby any person or group (other than certain permitted holders) becomes the beneficial owner of more than 50% of the total voting power of our voting shares and controls the composition of a majority of our board of directors, unless the primary purpose of such transaction or transactions, as applicable, is to create a holding entity for us that will be directly or indirectly owned in substantially the same proportions by the same persons that held our shares immediately prior to the consummation of such transaction. Term Unless terminated earlier, the 2016 share incentive plan will continue in effect for a term of ten years from the date of its adoption. Award Agreements Generally, equity awards granted under the 2016 share incentive plan are evidenced by an award agreement providing for the number of ordinary shares subject to the award, and the terms and conditions of the award, which must be consistent with the 2016 share incentive plan. Vesting Schedule The plan administrator determines the vesting schedule of each equity award granted under the 2016 share incentive plan, which vesting schedule will be set forth in the award agreement for such equity award. 132 Amendment and Termination of Plan Our board of directors may at any time amend, alter or discontinue the 2016 share incentive plan, subject to certain exceptions.

C. Board Practices Duties of Directors Under Cayman Islands law, our directors have a fiduciary duty to act honestly in good faith with a view to our best interests. Our directors also have a duty to exercise the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances. In fulfilling their duty of care to us, our directors must ensure compliance with our Amended and Restated Memorandum and Articles of Association. A shareholder has the right to seek damages if a duty owed by our directors is breached. The functions and powers of our board of directors include, among others: conducting and managing the business of our company; representing our company in contracts and deals; appointing attorneys for our company; select senior management such as managing directors and executive directors; providing employee benefits and pension; managing our company’s finance and bank accounts; 134 exercising the borrowing powers of our company and mortgaging the property of our company; and exercising any other powers conferred by the shareholders meetings or under our Amended and Restated Memorandum and Articles of Association. Appointment, Nomination and Terms of Directors Pursuant to our amended articles of association, our board of directors are classified into three classes of directors designated as Class I, Class II and Class III, each generally serving a three-year term unless earlier removed and except as described below. The Class I directors consist of Gary J. Wojtaszek, Satoshi Okada and Bruno Lopez; the Class II directors consist of Lee Chong Kwong, Lim Ah Doo, Chang Sun, and Judy Qing Ye; and the Class III directors consist of William Wei Huang, Sio Tat Hiang, Bin Yu and Zulkifli Baharudin. Class I directors initially retired from office by rotation and were up for re-election or re-appointment one year after the completion of our initial public offering. Class II directors will initially retire from office by rotation and be up for re-election or re-appointment two years after the completion of our initial public offering. Class III directors will initially retire from office by rotation and be up for re-election three years after the completion of our initial public offering. Our board currently consists of eleven (11) directors. Unless otherwise determined by us in a general meeting, our board will consist of not less than two (2) directors. There is no maximum number of directors unless otherwise determined by our shareholders in a general meeting, provided, however, that for so long as STT GDC has the right to appoint one or more directors to our board of directors, any change in the total number of directors on our board shall require the prior approval of the director or directors appointed by STT GDC. Our amended articles of association provide that for so long as STT GDC beneficially owns: not less than 25% of our issued and outstanding share capital, they may appoint three directors to our board of directors, including our vice-chairman; less than 25%, but not less than 15%, of our issued and outstanding share capital, they may appoint two directors to our board of directors, including our vice-chairman; and less than 15%, but not less than 8%, of our issued and outstanding share capital, they may appoint one director to our board of directors, including our vice-chairman, none of which appointments will be subject to a vote by our shareholders. In addition, the above rights of STT GDC may not be amended without the approval of STT GDC. Where STT GDC beneficially owns: less than 25%, but 15% or more, of our issued and outstanding share capital, then of the directors appointed by STT GDC, only two may remain in office, and the other director, who shall be determined by STT, or failing which shall be the director whose term is due to expire soonest, shall retire at the expiry of his/her term; less than 15%, but 8% or more, of our issued and outstanding share capital, then of the directors appointed by STT GDC, only one may remain in office, and the other directors, who shall be determined by STT, or failing which shall be the directors whose terms are due to expire soonest, shall retire at the expiry of their respective terms; less than 8% of our issued and outstanding share capital, then the directors appointed by STT GDC may not remain in office and all shall retire at the expiry of their respective terms. Any director appointed by STT GDC who retires pursuant to the foregoing sentence may, in the sole discretion of our nominating and corporate governance committee, be re-nominated and subject to re-election at the next general meeting of our shareholders. Our amended articles of association further provide that for so long as there are Class B ordinary shares outstanding: (i) the Class B shareholders shall be entitled to nominate one less than a simple majority, or five, of our directors (and such Class B shareholders shall have 20 votes per shares with respect to the resolutions approving the appointment or removal of such directors); and (ii) the nominating and corporate governance committee shall nominate one director, which one shall satisfy the requirements for an “independent director” within the meaning of the Nasdaq Stock Market Rules including the requirements for audit committee independence. As of and after such time as there ceases to be any Class B ordinary shares outstanding, all of the directors nominated by Class B shareholders shall retire from office at the expiry of their respective terms, and, if re-nominated, be subject to re-election at a subsequent general meeting of shareholders. Prior to such time, if any of the directors nominated by or subject to election by Class B shareholders at 20 votes per share (i) is not elected or (ii) ceases to be a director, then the Class B shareholders may appoint an interim replacement for each such director. Any person so appointed shall hold office until the next general meeting of our shareholders and be subject to re-nomination and re-election at such meeting.

The restricted share awards were granted subject to service and market conditions, or service and performance conditions, which are tied to our financial performance. In May, August and November 2017, we issued an aggregate of 502,000 restricted shares to directors pursuant to equity awards under the 2016 share incentive plan. In March, May, August and November 2018, we issued a total of 260,560 restricted shares to directors pursuant to equity awards under the 2016 share incentive plan. In March, May, August and November 2019, we issued a total of 237,312 restricted shares to directors pursuant to equity awards under the 2016 share incentive plan. These restricted shares were fully vested upon the date of grant and were granted to our directors in lieu of cash to settle a portion of remuneration for their services previously rendered. 144 Members (Shareholders) Agreements Pursuant to our amended members agreement entered into on May 19, 2016, we granted the holders of our registrable securities certain preferential rights, including registration rights, information and inspection rights, drag-along rights and pre-emptive rights. The amended members agreement also provides that our board of directors consists of nine directors, including (i) four directors appointed by STT GDC, (ii) two directors appointed by holders of 75% of our then outstanding preferred shares other than the Series C preferred shares, such holders voting together as a separate class on an as-converted basis, and (iii) three directors appointed by holders of a majority of our then outstanding ordinary shares, such holders voting as a separate class. The board composition arrangements under the amended members agreement will terminate immediately prior to the effectiveness of this registration statement. In addition, pursuant to our amended voting agreement entered into on May 19, 2016, the holders of our registrable securities have agreed to exercise voting rights so as to maintain the composition of the board of directors as set forth in the amended members agreement and described above. The amended voting agreement terminated on the date of the closing of our initial public offering. The drag-along rights terminated effective upon the closing of our initial public offering. The pre-emptive rights terminated immediately prior to the closing of our initial public offering. On November 7, 2016, we entered into an information rights agreement with STT GDC, pursuant to which we granted certain information rights to STT GDC for so long as it has the right to appoint directors under our articles of association. A copy of the information rights agreement has been filed with this annual report. Registration Rights Pursuant to our amended members agreement, we have also granted certain registration rights to holders of our registrable securities, which include our preferred shares and ordinary shares converted from preferred shares, for a period of up to five years from the closing of the offering. Set forth below is a description of the registration rights under the amended members agreement. Demand Registration Rights Under the terms of the amended members agreement dated May 19, 2016, among us and our existing shareholders, certain holders of our registrable securities, at any time from after the earlier of (i) six months after our initial public offering and (ii) three years after August 13, 2014, until the date that is five years after the closing of our initial public offering, have the right to demand that we file a registration statement under the Securities Act covering the registration of all or part of their registrable securities. We, however, are not obligated to effect a demand registration if, among other things, we have already effected two demand registrations. We have the right to defer filing of a registration statement for up to 90 days if our board of directors determine in good faith that filing of a registration will be materially detrimental to us, but we cannot exercise the deferral right more than once in any twelvemonth period. Piggyback Registration Rights If we propose to file a registration statement in connection with a public offering of securities of our company other than relating to an employee incentive plan, corporate reorganization, demand registration or Form S-3/F-3 registration then we must offer each holder of the registrable securities the opportunity to include their shares in the registration statement. Such requests for registrations are not counted as demand registrations. Form S-3/F-3 Registration Rights When eligible for use of form S-3/F-3, holders of our registrable securities then outstanding may request in writing that we effect a registration on Form S-3/F-3 so long, among other things, the gross proceeds of the securities to be sold under the registration statement exceeds US$1 million. We, however, are not obligated to effect a registration on Form S-3/F-3 if, among other things, we have already effected a registration within any six-month period preceding the date of the registration request. We have the right to defer filing of a registration statement for up to 90 days if our board of directors determine in good faith that filing of a registration will be materially detrimental to us, but we cannot exercise the deferral right more than once in any twelve-month period. 145 Registration pursuant to Form S-3/F-3 registration rights is not deemed to be a demand registration, and there is no limit on the number of times the holders may exercise their Form S-3/F-3 registration rights. Expenses of Registration We will pay all expenses incurred by us relating to any demand, piggyback or Form S-3/F-3 registration, except that the requesting holders shall bear the expense of any underwriting discounts and selling commissions relating to the offering of their securities. We will not be required to pay for any expenses of any registration proceeding begun pursuant to demand registration rights, unless subject to certain exception, if the registration request is subsequently withdrawn at the request of a majority of the holders of the registrable securities to be registered. Investor Rights Agreements In October 2017, in connection with an investment from CyrusOne Inc., or CyrusOne, of US$100 million, we granted to CyrusOne, now a major shareholder of ours, registration rights substantially similar to the foregoing registration rights granted to holders of our registrable securities pursuant to our amended members agreement described above. In October 2017, we also agreed to grant to STT GDC and SBCVC, two of our major shareholders, preemptive rights with respect to future private issuances of equity or equity-linked securities we conduct anytime in the eighteen months following CyrusOne’s investment, whereby STT GDC and SBCVC will have the right to subscribe for pro rata portions of any such future offerings based on their shareholdings at the time of the agreement. Copies of these rights agreements have been filed with this annual report. In March 2019, in connection with an investment from Ping An Overseas Holdings, of US$150 million, we entered into an amendment of our investment rights agreement with STT GDC (“Amendment No. 1”) to extend their preemptive rights with respect to future private issuances of equity or equity-linked securities we conduct anytime in the eighteen months following the investment by Ping An Overseas Holdings, whereby STT GDC has the right to subscribe for pro rata portions of any such future offerings based on their shareholdings at the time of the agreement. A copy of the form of this Amendment No. 1 has been filed with this annual report. In December 2019, in connection with our follow-on public offering of ADSs representing Class A ordinary shares, we entered into an amendment of our investment rights agreement with STT GDC (“Amendment No. 2”) to extend their preemptive rights with respect to future private issuances of equity or equity-linked securities we conduct anytime in the eighteen months following the follow-on public offering, whereby STT GDC has the right to subscribe for up to 35% of any such future offerings. A copy of this Amendment No. 2 has been filed with this annual report. Share Options See “Item 6. Directors, Senior Management and Employees—B. Compensation—Share Incentive Plans.” C. Interests of Experts and Counsel Not applicable. ITEM 8. FINANCIAL INFORMATION A. Consolidated Statements and Other Financial Information Please refer to Item 18 for a list of our annual consolidated financial statements filed as part of this annual report on Form 20-F. Legal Proceedings See “Item 4. Information on the Company—B. Business Overview—Legal Proceedings.” 146 Dividend Policy and Distributions Since our inception, we have not declared or paid any dividends on our shares. We do not have any present plan to pay any dividends on our Class A ordinary shares or ADSs in the foreseeable future. We intend to retain most, if not all, of our available funds and any future earnings to operate and expand our business. Any future determination to pay dividends will be made at the discretion of our board of directors and may be based on a number of factors, including our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant. If we pay any dividends, we will pay our ADS holders to the same extent as holders of our Class A ordinary shares, subject to the terms of the deposit agreement, including the fees and expenses payable thereunder. Cash dividends on our ordinary shares, if any, will be paid in U.S. dollars. We are an exempted company incorporated in the Cayman Islands. In order for us to distribute any dividends to our shareholders and ADS holders, we may rely on dividends distributed by our PRC subsidiaries. Certain payments from our PRC subsidiaries to us may be subject to PRC withholding income tax. In addition, regulations in the PRC currently permit payment of dividends of a PRC company only out of accumulated distributable after-tax profits as determined in accordance with its articles of association and the accounting standards and regulations in China. Each of our PRC subsidiaries is required to set aside at least 10% of its after-tax profit based on PRC accounting standards every year to a statutory common reserve fund until the aggregate amount of such reserve fund reaches 50% of the registered capital of such subsidiary. Such statutory reserves are not distributable as loans, advances or cash dividends. B. Significant Changes We have not experienced any significant changes since the date of our audited consolidated financial statements included in this annual report. ITEM 9. THE OFFER AND LISTING A.

Our shareholders conditionally adopted our eighth amended and restated memorandum and articles of association by way of a special resolution passed on October 18, 2016. Our eighth amended and restated memorandum and articles of association became effective immediately upon the completion of our initial public offering on December 6, 2016. C. Material Contracts In the past three fiscal years, we have not entered into any material contracts other than in the ordinary course of business or other than those described elsewhere in this annual report. D. Exchange Controls See “Item 4. Information on the Company—B. Business Overview—Regulatory Matters—Regulations Related to Foreign Currency Exchange and Dividend Distribution.” E. Taxation Cayman Islands Taxation The Cayman Islands currently levies no taxes on individuals or corporations based upon profits, income, gains or appreciation and there is no taxation in the nature of inheritance tax or estate duty or withholding tax applicable to us or to any holder of our ADSs and ordinary shares. There are no other taxes likely to be material to us levied by the Government of the Cayman Islands except for stamp duties which may be applicable on instruments executed in, or after execution brought within the jurisdiction of the Cayman Islands. No stamp duty is payable in the Cayman Islands on transfers of shares of Cayman Islands companies except those which hold interests in land in the Cayman Islands. The Cayman Islands is a party to a double tax treaty entered with the United Kingdom in 2010 but is otherwise not party to any double tax treaties. There are no exchange control regulations or currency restrictions in the Cayman Islands. Pursuant to Section 6 of the Tax Concessions Law (1999 Revision) of the Cayman Islands, we have obtained an undertaking from the Governor-in-Council: (i) that no law which is enacted in the Cayman Islands imposing any tax to be levied on profits or income or gains or appreciation shall apply to us or our operations; and (ii) that the aforesaid tax or any tax in the nature of estate duty or inheritance tax shall not be payable on our shares, debentures or other obligations. The undertaking for us is for a period of twenty years from June 8, 2004. 148 People’s Republic of China Taxation In March 2007, the National People’s Congress of China enacted the Enterprise Income Tax Law, which became effective on January 1, 2008 and was amended on December 29, 2018. The Enterprise Income Tax Law provides that enterprises organized under the laws of jurisdictions outside China with their “de facto management bodies” located within China may be considered PRC resident enterprises and therefore subject to PRC enterprise income tax at the rate of 25% on their worldwide income. The Implementation Rules of the Enterprise Income Tax Law further defines the term “de facto management body” as the management body that exercises substantial and overall management and control over the business, personnel, accounts and properties of an enterprise. While we do not currently consider our company or any of our overseas subsidiaries to be a PRC resident enterprise, there is a risk that the PRC tax authorities may deem our company or any of our overseas subsidiaries as a PRC resident enterprise since a substantial majority of the members of our management team as well as the management team of some of our overseas subsidiaries are located in China, in which case we or the overseas subsidiaries, as the case may be, would be subject to the PRC enterprise income tax at the rate of 25% on worldwide income. If the PRC tax authorities determine that our Cayman Islands holding company is a “resident enterprise” for PRC enterprise income tax purposes, a number of unfavorable PRC tax consequences could follow. One example is a 10% withholding tax would be imposed on dividends we pay to our non-PRC enterprise shareholders and with respect to gains derived by our non-PRC enterprise shareholders from transferring our shares or ADSs. It is unclear whether, if we are considered a PRC resident enterprise, holders of our shares or ADSs would be able to claim the benefit of income tax treaties or agreements entered into between China and other countries or areas. Material United States Federal Income Tax Considerations The following summary describes the material United States federal income tax consequences of the purchase, ownership and disposition of our ADSs and ordinary shares as of the date hereof. This summary is only applicable to ADSs and ordinary shares held as capital assets by a United States Holder (as defined below). As used herein, the term “United States Holder” means a beneficial owner of our ADSs or ordinary shares that is for United States federal income tax purposes: an individual citizen or resident of the United States; a corporation (or other entity treated as a corporation for United States federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia; an estate the income of which is subject to United States federal income taxation regardless of its source; or a trust if it (i) is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust or (ii) has a valid election in effect under applicable United States Treasury regulations to be treated as a United States person. The discussion below is based upon the provisions of the Internal Revenue Code of 1986, as amended, or the Code, and regulations, rulings and judicial decisions thereunder as of the date hereof, and such authorities may be replaced, revoked or modified so as to result in United States federal income tax consequences different from those discussed below. In addition, this summary is based, in part, upon representations made by the depositary to us and assumes that the deposit agreement, and all other related agreements, will be performed in accordance with their terms. This summary does not represent a detailed description of the United States federal income tax consequences applicable to you if you are subject to special treatment under the United States federal income tax laws, including if you are: a dealer in securities or currencies; a financial institution; a regulated investment company; 149 a real estate investment trust; an insurance company; a tax-exempt organization; a person holding our ADSs or ordinary shares as part of a hedging, integrated or conversion transaction, a constructive sale or a straddle; a trader in securities that has elected the mark-to-market method of accounting for your securities; a person liable for alternative minimum tax; a person who owns or is deemed to own 10% or more of our stock (by vote or value); a partnership or other pass-through entity for United States federal income tax purposes; a person required to accelerate the recognition of any item of gross income with respect to our ADSs or ordinary shares as a result of such income being recognized on an applicable financial statement; or a person whose “functional currency” is not the United States dollar. If a partnership (or other entity treated as a partnership for United States federal income tax purposes) holds our ADSs or ordinary shares, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership holding our ADSs or ordinary shares, you should consult your tax advisors. This summary does not contain a detailed description of all the United States federal income tax consequences to you in light of your particular circumstances and does not address the Medicare tax on net investment income or the effects of any state, local or non-United States tax laws. If you are considering the purchase, ownership or disposition of our ADSs or ordinary shares, you should consult your own tax advisors concerning the United States federal income tax consequences to you in light of your particular situation as well as any consequences arising under the laws of any other taxing jurisdiction. ADSs If you hold ADSs, for United States federal income tax purposes, you generally will be treated as the owner of the underlying ordinary shares that are represented by such ADSs. Accordingly, deposits or withdrawals of ordinary shares for ADSs will not be subject to United States federal income tax. Taxation of Dividends Subject to the discussion under “—Passive Foreign Investment Company” below, the gross amount of any distributions on the ADSs or ordinary shares (including any amounts withheld to reflect PRC withholding taxes) will be taxable as dividends, to the extent paid out of our current or accumulated earnings and profits, as determined under United States federal income tax principles. Such income (including withheld taxes) will be includable in your gross income as ordinary income on the day actually or constructively received by you, in the case of the ordinary shares, or by the depositary, in the case of ADSs. Such dividends will not be eligible for the dividends received deduction allowed to corporations under the Code. 150 With respect to non-corporate United States Holders, certain dividends received from a qualified foreign corporation may be subject to reduced rates of taxation. A foreign corporation is treated as a qualified foreign corporation with respect to dividends received from that corporation on ordinary shares (or ADSs backed by such shares) that are readily tradable on an established securities market in the United States. Our ADSs are listed on the Nasdaq. United States Treasury Department guidance indicates that our ADSs are readily tradable on an established securities market in the United States. Thus, subject to the discussion under “— Passive Foreign Investment Company” below, we believe that dividends we pay on our ADSs will meet the conditions required for the reduced tax rate. Since we do not expect that our ordinary shares will be listed on an established securities market, we do not believe that dividends that we pay on our ordinary shares that are not represented by ADSs will meet the conditions required for these reduced tax rates. There also can be no assurance that our ADSs will continue to be readily tradable on an established securities market in later years. Consequently, there can be no assurance that our ADSs will continue to be afforded the reduced tax rates. A qualified foreign corporation also includes a foreign corporation that is eligible for the benefits of certain income tax treaties with the United States. In the event that we are deemed to be a PRC resident enterprise under the PRC tax law (see “—People’s Republic of China Taxation” above), we may be eligible for the benefits of the income tax treaty between the United States and the PRC, or the Treaty. In that case, dividends we pay on our ordinary shares would be eligible for the reduced rates of taxation whether or not the shares are readily tradable on an established securities market in the United States, and whether or not the shares are represented by ADSs. Non- corporate United States Holders that do not meet a minimum holding period requirement during which they are not protected from the risk of loss or that elect to treat the dividend income as “investment income” pursuant to Section 163(d)(4) of the Code will not be eligible for the reduced rates of taxation regardless of our status as a qualified foreign corporation. In addition, the rate reduction will not apply to dividends if the recipient of a dividend is obligated to make related payments with respect to positions in substantially similar or related property. This disallowance applies even if the minimum holding period has been met. You should consult your own tax advisors regarding the application of these rules given your particular circumstances. Non-corporate United States Holders will not be eligible for reduced rates of taxation on any dividends received from us if we are a passive foreign investment company, or PFIC, in the taxable year in which such dividends are paid or in the preceding taxable year (see “—Passive Foreign Investment Company” below). In the event that we are deemed to be a PRC resident enterprise under the PRC tax law, you may be subject to PRC withholding taxes on dividends paid to you with respect to the ADSs or ordinary shares. See “—People’s Republic of China Taxation.” In that case, subject to certain conditions and limitations (including a minimum holding period requirement), PRC withholding taxes on dividends may be treated as foreign taxes eligible for credit against your United States federal income tax liability. For purposes of calculating the foreign tax credit, dividends paid on the ADSs or ordinary shares will be treated as foreign- source income and will generally constitute passive category income. The rules governing the foreign tax credit are complex. You are urged to consult your tax advisor regarding the availability of the foreign tax credit under your particular circumstances. To the extent that the amount of any distribution exceeds our current and accumulated earnings and profits, as determined under United States federal income tax principles, the distribution ordinarily would be treated, first, as a tax-free return of capital, causing a reduction in the adjusted basis of the ADSs or ordinary shares (thereby increasing the amount of gain, or decreasing the amount of loss, to be recognized by you on a subsequent disposition of the ADSs or ordinary shares), and, second, the balance in excess of adjusted basis ordinarily would be taxed as capital gain recognized on a sale or exchange. However, we do not expect to determine our earnings and profits in accordance with United States federal income tax principles. Therefore, you should expect that distributions will generally be reported to the Internal Revenue Service, or IRS, and taxed to you as dividends (as discussed above), even if they might ordinarily be treated as a tax-free return of capital or as capital gain. Passive Foreign Investment Company Based on the past and projected composition of our income and assets, and the valuation of our assets, including goodwill, we do not believe we were a PFIC for our taxable year ended December 31, 2019 and we do not expect to be a PFIC for our taxable year ending December 31, 2020 or in future taxable years, although there can be no assurance in this regard, since the determination of our PFIC status cannot be made until the end of a taxable year and depends significantly on the composition of our assets and income throughout the year. In general, we will be a PFIC for any taxable year in which: at least 75% of our gross income is passive income, or 151 at least 50% of the value (based on a quarterly average) of our assets is attributable to assets that produce or are held for the production of passive income. For this purpose, passive income generally includes dividends, interest, royalties and rents (other than royalties and rents derived in the active conduct of a trade or business and not derived from a related person), as well as gains from the sale of assets (such as stock) that produce passive income, foreign currency gains, and certain other categories of income. If we own at least 25% (by value) of the stock of another corporation, we will be treated, for purposes of determining whether we are a PFIC, as owning our proportionate share of the other corporation’s assets and receiving our proportionate share of the other corporation’s income. However, it is not entirely clear how the contractual arrangements between us and our consolidated VIEs will be treated for purposes of the PFIC rules. For United States federal income tax purposes, we consider ourselves to own the stock of our consolidated VIEs. If it is determined, contrary to our view, that we do not own the stock of our consolidated VIEs for United States federal income tax purposes (for instance, because the relevant PRC authorities do not respect these arrangements), that would alter the composition of our income and assets for purposes of testing our PFIC status, and may cause us to be treated as a PFIC. The determination of whether we are a PFIC is made annually. Accordingly, it is possible that we may become a PFIC in the current or any future taxable year due to changes in our asset or income composition. The calculation of the value of our assets will be based, in part, on the quarterly market value of our ADSs, which is subject to change. If we are a PFIC for any taxable year during which you hold our ADSs or ordinary shares and you do not make a timely mark-to-market election, as described below, you will be subject to special—and generally very unfavorable—tax rules with respect to any “excess distribution” received and any gain realized from a sale or other disposition, including a pledge, of ADSs or ordinary shares. Distributions received in a taxable year that are greater than 125% of the average annual distributions received during the shorter of the three preceding taxable years or your holding period for the ADSs or ordinary shares will be treated as excess distributions. Under these special tax rules: the excess distribution or gain will be allocated ratably over your holding period for the ADSs or ordinary shares, the amount allocated to the current taxable year, and any taxable year prior to the first taxable year in which we were a PFIC, will be treated as ordinary income, and the amount allocated to each other year will be subject to tax at the highest tax rate in effect for that year and the interest charge generally applicable to underpayments of tax will be imposed on the resulting tax attributable to each such year. Although the determination of whether we are a PFIC is made annually, if we are a PFIC for any taxable year in which you hold our ADSs or ordinary shares, you will generally be subject to the special tax rules described above for that year and for each subsequent year in which you hold the ADSs or ordinary shares (even if we do not qualify as a PFIC in any subsequent years). However, if we cease to be a PFIC, you can avoid the continuing impact of the PFIC rules by making a special election to recognize gain as if your ADSs or ordinary shares had been sold on the last day of the last taxable year during which we were a PFIC. You are urged to consult your own tax advisor about this election. In certain circumstances, in lieu of being subject to the special tax rules discussed above, you may make a mark-to-market election with respect to your ADSs or ordinary shares provided such ADSs or ordinary shares are treated as “marketable stock.” The ADSs or ordinary shares generally will be treated as marketable stock if the ADSs or ordinary shares are “regularly traded” on a “qualified exchange or other market” (within the meaning of the applicable Treasury regulations). Under current law, the mark-to- market election may be available to holders of ADSs as the ADSs are listed on the Nasdaq, which constitutes a qualified exchange, although there can be no assurance that the ADSs will be “regularly traded” for purposes of the mark-to-market election. It should also be noted that only the ADSs and not the ordinary shares are listed on the Nasdaq. Consequently, if you are a holder of ordinary shares that are not represented by ADSs, you generally will not be eligible to make a mark-to-market election. If you make an effective mark-to-market election, for each taxable year that we are a PFIC, you will include as ordinary income the excess of the fair market value of your ADSs at the end of the year over your adjusted basis in the ADSs. You will be entitled to deduct as an ordinary loss in each such year the excess of your adjusted basis in the ADSs over their fair market value at the end of the year, but only to the extent of the net amount previously included in income as a result of the mark-to-market election. If you make an effective mark-to-market election, any gain you recognize upon the sale or other disposition of your ADSs in a year that we are a PFIC will be treated as ordinary income and any loss will be treated as ordinary loss, but only to the extent of the net amount previously included in income as a result of the mark-to-market election. 152 Your adjusted basis in the ADSs will be increased by the amount of any income inclusion and decreased by the amount of any deductions under the mark-to-market rules. If you make a mark-to-market election it will be effective for the taxable year for which the election is made and all subsequent taxable years unless the ADSs are no longer regularly traded on a qualified exchange or other market, or the IRS consents to the revocation of the election. You are urged to consult your tax advisor about the availability of the mark-to-market election, and whether making the election would be advisable in your particular circumstances. A different election, known as the “qualified electing fund,” or “QEF” election, is generally available to holders of PFIC stock, but requires that the corporation provide the holders with a “PFIC Annual Information Statement” containing certain information necessary for the election, including the holder’s pro rata share of the corporation’s earnings and profits and net capital gains for each taxable year, computed according to United States federal income tax principles. We do not intend, however, to determine our earnings and profits or net capital gain under United States federal income tax principles, nor do we intend to provide United States Holders with a PFIC Annual Information Statement. Therefore, you should not expect to be eligible to make this election. If we are a PFIC for any taxable year during which you hold our ADSs or ordinary shares and any of our non-United States subsidiaries is also a PFIC, you will be treated as owning a proportionate amount (by value) of the shares of the lower-tier PFIC for purposes of the application of these rules. You are urged to consult your tax advisors about the application of the PFIC rules to any of our subsidiaries. You will generally be required to file IRS Form 8621 if you hold our ADSs or ordinary shares in any year in which we are classified as a PFIC. You are urged to consult your tax advisors concerning the United States federal income tax consequences of holding ADSs or ordinary shares if we are considered a PFIC in any taxable year. Taxation of Capital Gains For United States federal income tax purposes, you will recognize taxable gain or loss on any sale or exchange of ADSs or ordinary shares in an amount equal to the difference between the amount realized for the ADSs or ordinary shares and your adjusted basis in the ADSs or ordinary shares. Subject to the discussion under “—Passive Foreign Investment Company” above, such gain or loss will generally be capital gain or loss and will generally be long-term capital gain or loss if you have held the ADSs or ordinary shares for more than one year. Long-term capital gains of non-corporate United States Holders (including individuals) are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations. Any gain or loss recognized by you will generally be treated as United States source gain or loss. However, if we are treated as a PRC resident enterprise for PRC tax purposes and PRC tax is imposed on any gain, and if you are eligible for the benefits of the Treaty, you may elect to treat such gain as PRC source gain. If you are not eligible for the benefits of the Treaty or you fail to make the election to treat any gain as PRC source, then you may not be able to use the foreign tax credit arising from any PRC tax imposed on the disposition of our ADSs or ordinary shares unless such credit can be applied (subject to applicable limitations) against United States federal income tax due on other income derived from foreign sources in the same income category (generally, the passive category). You are urged to consult your tax advisors regarding the tax consequences if any PRC tax is imposed on gain on a disposition of our ordinary shares or ADSs, including the availability of the foreign tax credit and the election to treat any gain as PRC source, under your particular circumstances. Information Reporting and Backup Withholding In general, information reporting will apply to dividends in respect of our ADSs or ordinary shares and the proceeds from the sale, exchange or other disposition of our ADSs or ordinary shares that are paid to you within the United States (and in certain cases, outside the United States), unless you are an exempt recipient such as a corporation. A backup withholding tax may apply to such payments if you fail to provide a taxpayer identification number or certification of exempt status or fail to report in full dividend and interest income. Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against your United States federal income tax liability provided the required information is furnished to the IRS in a timely manner. Certain United States Holders are required to report information relating to our ADSs or ordinary shares by attaching a complete Form 8938, Statement of Specified Foreign Financial Assets, with their tax returns for each year in which they hold ADSs or ordinary shares. Significant penalties can apply if you are required to file this form and you fail to do so. You are urged to consult your own tax advisor regarding this and other information reporting requirements relating to your ownership of the ADSs or ordinary shares. 153 F.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Interest Rate Risk Our exposure to interest rate risk primarily relates to interest expenses incurred in respect of bank borrowings, bonds payable and capital lease and other financing obligations and interest income generated by excess cash, which is mostly held in interest- bearing bank deposits. We have not used derivative financial instruments in our investment portfolio. Interest earning instruments and interest-bearing obligations carry a degree of interest rate risk. We have not been exposed to material risks due to changes in market interest rates. However, our future interest income and interest expenses may fluctuate due to changes in market interest rates. Foreign Exchange Risk All of our revenue and substantially all of our expenses are denominated in Renminbi. We do not believe that we currently have any significant direct foreign exchange risk and have not used any derivative financial instruments to hedge exposure to such risk. Although in general our exposure to foreign exchange risks should be limited, the value of your investment in our ADSs will be affected by the exchange rate between the U.S. dollar and the Renminbi because the value of our business is effectively denominated in Renminbi, while our ADSs will be traded in U.S. dollars. 154 The conversion of Renminbi into foreign currencies, including U.S. dollars, is based on rates set by the PBOC. On July 21, 2005, the PRC government changed its policy of pegging the value of the Renminbi to the U.S. dollar. The PRC government allowed the Renminbi to appreciate by more than 20% against the U.S. dollar between July 2005 and July 2008. Between July 2008 and June 2010, the exchange rate between the Renminbi and the U.S. dollar had been stable and traded within a narrow band. Since June 2010, the Renminbi has fluctuated against the U.S. dollar, at times significantly and unpredictably. On November 30, 2015, the Executive Board of the International Monetary Fund (IMF) completed the regular five-year review of the basket of currencies that make up the Special Drawing Right, or the SDR, and decided that with effect from October 1, 2016, Renminbi is determined to be a freely usable currency and will be included in the SDR basket as a fifth currency, along with the U.S. dollar, the Euro, the Japanese yen and the British pound. From December 31, 2015 to December 31, 2016, the Renminbi depreciated approximately 6.7% against the U.S. dollar. In 2017, however, the RMB appreciated approximately 6.7% against the U.S. dollar; and in 2018, the RMB depreciated approximately 5.7% against the U.S. dollar. With the development of the foreign exchange market and progress towards interest rate liberalization and approximately 5.7% against the U.S. dollar Renminbi internationalization, the PRC government may in the future announce further changes to the exchange rate system, and we cannot assure you that the Renminbi will not appreciate or depreciate significantly in value against the U.S. dollar in the future. Starting from the beginning of 2019, the Renminbi has depreciated significantly against the U.S. dollar again. In early August 2019, The People’s Bank of China, or the PBOC, set the daily reference rate for the Renminbi at RMB7.0039 to US$1.00, the first time that the exchange rate of Renminbi to U.S. dollar exceeded RMB7.0000 to US$1.00 since 2008. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the Renminbi and the U.S. dollar in the future. It remains unclear what further fluctuations may occur or what impact this will have on our results of operations. To the extent that we need to convert U.S. dollars into Renminbi for our operations, appreciation of the Renminbi against the U.S. dollar would have an adverse effect on the Renminbi amount we receive from the conversion. Conversely, if we decide to convert Renminbi into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against the Renminbi would have a negative effect on the U.S. dollar amounts available to us. Inflation Since our inception, inflation in China has not materially affected our results of operations. According to the National Bureau of Statistics of China, the consumer price index in China was 1.6%, 2.1% and 2.9% in 2017, 2018 and 2019, respectively. Although we have not been materially affected by inflation in the past, we may be affected if China experiences higher rates of inflation in the future. ITEM 12. DESCRIPTION OF SECURITIES OTHER THAN EQUITY SECURITIES A. Debt Securities Not applicable. B. Warrants and Rights Not applicable. C. Other Securities Not applicable. 155 D. American Depositary Shares Fees and Charges As an ADS holder, you will be required to pay the following service fees to the depositary bank: Service: Issuance of ADSs, including issuances resulting from a distribution of shares or rights or other property Cancellation of ADSs, including in the case of termination of the deposit agreement Distribution of cash dividends or other cash distributions Distribution of ADSs pursuant to share dividends, free share distributions or exercise of rights Distribution of securities other than ADSs or rights to purchase ADSs or additional ADSs Depositary services Transfer of ADRs $5.00 for each 100 ADSs (or portion thereof) issued Fee: $5.00 for each 100 ADSs (or portion thereof) cancelled Up to $0.05 per ADS held Up to $0.05 per ADS held A fee being in an amount equal to the fee for the execution and delivery of ADSs which would have been charged as a result of the deposit of such securities An aggregate fee of $0.05 per ADS per calendar year (or portion thereof) for services performed by the Depositary in administering the ADRs $1.50 per certificate presented for transfer As an ADS holder, you will also be responsible to pay certain fees and expenses incurred by the depositary bank and certain taxes and governmental charges such as: Fees for the transfer and registration of ordinary shares charged by the registrar and transfer agent for the ordinary shares in the Cayman Islands (i.e., upon deposit and withdrawal of ordinary shares). Expenses incurred for converting foreign currency into U.S. dollars. Expenses for cable, telex and fax transmissions and for delivery of securities. Taxes and duties upon the transfer of securities, including any applicable stamp duties, any stock transfer charges or withholding taxes (i.e., when ordinary shares are deposited or withdrawn from deposit). Fees and expenses incurred in connection with the delivery or servicing of ordinary shares on deposit. Fees and expenses incurred in connection with complying with exchange control regulations and other regulatory requirements applicable to ordinary shares, deposited securities, ADSs and ADRs. Any applicable fees and penalties thereon. The depositary fees payable upon the issuance and cancellation of ADSs are typically paid to the depositary bank by the brokers (on behalf of their clients) receiving the newly issued ADSs from the depositary bank and by the brokers (on behalf of their clients) delivering the ADSs to the depositary bank for cancellation. The brokers in turn charge these fees to their clients. Depositary fees payable in connection with distributions of cash or securities to ADS holders and the depositary services fee are charged by the depositary bank to the holders of record of ADSs as of the applicable ADS record date. 156 The depositary fees payable for cash distributions are generally deducted from the cash being distributed or by selling a portion of distributable property to pay the fees. In the case of distributions other than cash (i.e., share dividends, rights), the depositary bank charges the applicable fee to the ADS record date holders concurrent with the distribution. In the case of ADSs registered in the name of the investor (whether certificated or uncertificated in direct registration), the depositary bank sends invoices to the applicable record date ADS holders. In the case of ADSs held in brokerage and custodian accounts (via DTC), the depositary bank generally collects its fees through the systems provided by DTC (whose nominee is the registered holder of the ADSs held in DTC) from the brokers and custodians holding ADSs in their DTC accounts. The brokers and custodians who hold their clients’ ADSs in DTC accounts in turn charge their clients’ accounts the amount of the fees paid to the depositary banks. In the event of refusal to pay the depositary fees, the depositary bank may, under the terms of the deposit agreement, refuse the requested service until payment is received or may set off the amount of the depositary fees from any distribution to be made to the ADS holder. The depositary has agreed to reimburse us for a portion of certain expenses we incur that are related to establishment and maintenance of the ADR program, including investor relations expenses. There are limits on the amount of expenses for which the depositary will reimburse us, but the amount of reimbursement available to us is not related to the amounts of fees the depositary collects from investors. Further, the depositary has agreed to reimburse us certain fees payable to the depositary by holders of ADSs. Neither the depositary nor we can determine the exact amount to be made available to us because (i) the number of ADSs that will be issued and outstanding, (ii) the level of service fees to be charged to holders of ADSs and (iii) our reimbursable expenses related to the program are not known at this time. Payments by Depositary In 2019, we did not receive any payments from JPMorgan Chase Bank, N.A., the depositary bank for our ADR program, for reimbursement of investor relations expenses and other program related expenses. ITEM 13. DEFAULTS, DIVIDEND ARREARAGES AND DELINQUENCIES None of these events occurred in any of the years ended December 31, 2017, 2018 and 2019. PART II. ITEM 14. MATERIAL MODIFICATIONS TO THE RIGHTS OF SECURITY HOLDERS AND USE OF PROCEEDS A. Modifications of Rights In October 2017, in connection with an investment from CyrusOne Inc., or CyrusOne, of US$100 million, we granted to CyrusOne, now a major shareholder of ours, registration rights substantially similar to the registration rights granted to holders of our registrable securities pursuant to our amended members agreement. See “Item 10. Additional Information—B. Memorandum and Articles of Association” for a description of the rights of securities holders. In October 2017, we also agreed to grant to STT GDC and SBCVC, two of our major shareholders, preemptive rights with respect to future private issuances of equity or equity-linked securities we conduct anytime in the eighteen months following CyrusOne’s investment, whereby STT GDC and SBCVC had the right to subscribe for pro rata portions of any such future offerings based on their shareholdings at the time of the agreement. Copies of these rights agreements have been filed with this annual report. In March 2019, in connection with an investment from Ping An Overseas Holdings, of US$150 million, we entered into an amendment of our investment rights agreement with STT GDC (“Amendment No. 1”) to extend their preemptive rights with respect to future private issuances of equity or equity-linked securities we conduct anytime in the eighteen months following the investment by Ping An Overseas Holdings, whereby STT GDC has the right to subscribe for pro rata portions of any such future offerings based on their shareholdings at the time of the agreement. A copy of the form of this Amendment No. 1 has been filed with this annual report. 157 In December 2019, in connection with our follow-on public offering of ADSs representing Class A ordinary shares, we entered into an amendment of our investment rights agreement with STT GDC (“Amendment No. 2”) to extend their preemptive rights with respect to future private issuances of equity or equity-linked securities we conduct anytime in the eighteen months following the offering, whereby STT GDC has the right to subscribe for up to 35% of any such future offerings. A copy of this Amendment No. 2 has been filed with this annual report. E.

ITEM 15. CONTROLS AND PROCEDURES Evaluation of Disclosure Controls and Procedures As of the end of the period covered by this annual report, an evaluation has been carried out under the supervision and with the participation of our management, including our chief executive officer and our chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as such term is defined under Rules 13a-15(e) and 15d-15(e) promulgated under the Exchange Act. Based on that evaluation, our chief executive officer and chief financial officer have concluded that our disclosure controls and procedures are effective in ensuring that material information required to be disclosed in this annual report is recorded, processed, summarized and reported to them for assessment, and required disclosure is made within the time period specified in the rules and forms of the SEC. Management’s Annual Report on Internal Control over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended, for our company. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements in accordance with generally accepted accounting principles and includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets, (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with U.S. GAAP and that a company’s receipts and expenditures are being made only in accordance with authorizations of our management and directors, and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on our consolidated financial statements. As required by Section 404 of the Sarbanes-Oxley Act of 2002 and related rules as promulgated by the Securities and Exchange Commission, our management including our Chief Executive Officer and Chief Financial Officer assessed the effectiveness of internal control over financial reporting as of December 31, 2019 using the criteria set forth in the report “Internal Control— Integrated Framework (2013)” published by the Committee of Sponsoring Organizations of the Treadway Commission (known as COSO). Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2019. Because of its inherent limitations, a system of internal control over financial reporting can provide only reasonable assurance with respect to consolidated financial statements preparation and presentation and may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Our independent registered public accounting firm, KPMG Huazhen LLP, has audited the effectiveness of our internal control over financial reporting as of December 31, 2019, as stated in its report, which appears on page F-2 of this annual report. 159 Changes in Internal Control over Financial Reporting There were no changes in our internal control over financial reporting that occurred during the period covered by this annual report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. ITEM 16A. AUDIT COMMITTEE FINANCIAL EXPERT Our Board of Directors has determined that each of Lim Ah Doo and Bin Yu, who are independent directors, satisfies the criteria of an audit committee financial expert as defined in Item 16A of the instruction to Form 20-F. ITEM 16B. CODE OF ETHICS We have adopted a code of business conduct which applies to our directors, employees, advisors and officers, including our Chief Executive Officer and Chief Financial Officer. No changes have been made to the code of business conduct since its adoption and no waivers have been granted therefrom to our directors or employees. We have filed our code of business conduct as an exhibit to our F-1 registration statement (File No. 333-213951), as amended, initially filed with the SEC on October 4, 2016, and a copy is available to any shareholder upon request. This code of business conduct is also available on our website at investors.gds- services.com. ITEM 16C.

ITEM 16D. EXEMPTIONS FROM THE LISTING STANDARDS FOR AUDIT COMMITTEES None. 160 ITEM 16E. PURCHASE OF EQUITY SECURITIES BY THE ISSUER AND AFFILIATED PURCHASERS None. ITEM 16F. CHANGE IN REGISTRANT’S CERTIFYING ACCOUNTANT Not applicable. ITEM 16G. CORPORATE GOVERNANCE We are a “foreign private issuer” (as such term is defined in Rule 3b-4 under the Exchange Act), and our ADSs, each representing eight ordinary shares, are listed on the Nasdaq Global Market. Nasdaq Stock Market Rules permit a foreign private issuer like us to follow the corporate governance practices of its home country. Certain corporate governance practices in the Cayman Islands, which is our home country, may differ significantly from the Nasdaq corporate governance listing standards. For instance, we are not required to: have a majority of the board be independent (although all of the members of the audit committee must be independent under the Exchange Act); have a compensation committee or a nominations or corporate governance committee consisting entirely of independent directors; or have regularly scheduled executive sessions with only independent directors each year. We have relied on and intend to continue to rely on some of these exemptions. ITEM 16H. MINE SAFETY Not applicable. ITEM 17. FINANCIAL STATEMENTS PART III.

SIGNATURES Date: April 17, 2020 GDS Holdings Limited By: /s/ William Wei Huang Name: William Wei Huang Title: Chief Executive Officer 169 GDS HOLDINGS LIMITED AND SUBSIDIARIES Index to Consolidated Financial Statements Report of Independent Registered Public Accounting Firm Consolidated Balance Sheets as of December 31, 2018 and 2019 Consolidated Statements of Operations for the years ended December 31, 2017, 2018 and 2019 Consolidated Statements of Comprehensive Loss for the years ended December 31, 2017, 2018 and 2019 Consolidated Statements of Changes in Shareholders’ Equity for the years ended December 31, 2017, 2018 and 2019 Consolidated Statements of Cash Flows for the years ended December 31, 2017, 2018 and 2019 Notes to Consolidated Financial Statements Page F-2 F-4 F-5 F-6 F-7 F-8 F-10 F-1 Report of Independent Registered Public Accounting Firm To the Board of Directors and Shareholders GDS Holdings Limited: Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting We have audited the accompanying consolidated balance sheets of GDS Holdings Limited and subsidiaries (“the Company”) as of December 31, 2018 and 2019, the related consolidated statements of operations, comprehensive loss, changes in shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2019, and the related notes (collectively, the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2019, and the results of its operations and its cash flows for each of the years in the three- year period ended December 31, 2019, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019 based on criteria established in Internal Control — Integrated Framework (2013) issued by the COSO. Change in Accounting Principle As discussed in Note 2 to the consolidated financial statements, the Company has changed its method of accounting for leases in 2019 due to the adoption of Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842), and for revenue recognition in 2018 due to the adoption of ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). Basis for Opinions The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on these consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. F-2 Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates. Evaluation of the realizability of deferred tax assets associated with the Company’s net operating loss carry forwards As discussed in Notes 2 and 20 of the consolidated financial statements, the Company’s net deferred tax assets were RMB73 million as of December 31, 2019. This balance is net of a valuation allowance of RMB206 million recorded by the Company. The deferred tax assets for net operating loss carry forwards and related valuation allowance were RMB235 million and RMB182 million, respectively. The Company evaluated the realizability of the deferred tax assets associated with the Company’s net operating loss carry forwards to determine whether there was more than a 50% likelihood that these deferred tax assets would be realized, based on the Company’s expectations of future taxable income and timing of net operating losses carry forwards expirations. We identified the evaluation of the realizability of deferred tax assets associated with the Company's net operating loss carry forwards as a critical audit matter. A high degree of subjective auditor judgment was required to evaluate that sufficient future taxable income will be generated to support the realization of the net operating losses carry forwards before their expiration. The primary procedures we performed to address this critical audit matter included the following. We tested certain internal controls over the Company’s process for evaluating the realizability of deferred tax assets for the net operating loss carry forwards, including controls related to the development of the forecast of the future taxable income and the timing of utilization of net operating losses carry forwards. We evaluated the assumptions used in the development of forecast of future taxable income by comparing to historical actuals while considering the Company’s operation plans for the data centers' forecasted utilization rates.

F-9 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) 1 DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION (a) Description of business GDS Holdings Limited (the “Parent” or “GDS Holdings”) was incorporated in the Cayman Islands on December 1, 2006. GDS Holdings and its consolidated subsidiaries and consolidated variable interest entities (collectively referred to as “the Company”) are principally engaged in providing colocation, managed hosting and managed cloud services in the People’s Republic of China (the “PRC” excluding Taiwan, the Hong Kong Special Administrative Region (the “Hong Kong SAR”) and the Macao Special Administrative Region for the purposes of these consolidated financial statements only) and Hong Kong SAR. The Company operates its data centers in Hong Kong SAR, Shanghai Municipality, Beijing Municipality, Jiangsu Province, Guangdong Province, Sichuan Province and Hebei Province of the PRC and serves customers that primarily operate in the cloud, internet and banking industries. (b) Basis of presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“US GAAP”). The consolidated financial statements are presented in Renminbi (“RMB”), rounded to the nearest thousand. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (a) Principles of Consolidation The accompanying consolidated financial statements include the financial statements of GDS Holdings Limited, its subsidiaries and consolidated variable interest entities and variable interest entities’ subsidiaries for which the Company is the primary beneficiary. In certain regions of the PRC, the Company’s operations are conducted through Shanghai Xinwan Enterprise Management Co., Ltd. (“Management HoldCo”), Beijing Wanguo Chang’an Science and Technology Co., Ltd. (“GDS Beijing”), GDS Beijing’s subsidiaries and Shanghai Shu’an Data Services Co., Ltd. (“GDS Shanghai”) (referred to as the “VIEs”) to comply with the PRC laws and regulations, which prohibit foreign investments in companies that are engaged in data center related business in those regions. Individuals acting as nominee equity holders ultimately hold the legal equity interests of the VIEs on behalf of the Company. The equity holders of GDS Beijing and GDS Shanghai were William Wei Huang, CEO of the Company, and his relative. In order to enhance corporate governance and facilitate administration of the VIEs, in December 2019, GDS Holdings completed transfer of ownership of the 100% equity interest of GDS Beijing and GDS Shanghai from William Wei Huang and his relative to a newly established holding company, Management HoldCo. The entire equity interest in Management HoldCo is held by a number of management personnel designated by the Board of Directors of GDS Holdings. In conjunction with the transfer of legal ownership, GDS (Shanghai) Investment Co., Ltd. (“GDS Investment Company”), a subsidiary of GDS Holdings, entered into a series of contractual arrangements with Management HoldCo, its shareholders, GDS Beijing and GDS Shanghai to replace the previous contractual arrangements with GDS Beijing and GDS Shanghai on substantially the same terms under such previous contractual arrangements. The previous contractual arrangements were terminated simultaneously when the current contractual arrangements came into effect, and the subsidiary of GDS Holdings under the previous and current contractual arrangements is the same entity, namely GDS Investment Company. GDS Holdings also replaced the sole director of GDS Shanghai and certain subsidiaries of GDS Beijing with a board of three directors. William Wei Huang acts as the Chairman of the board of directors of Management HoldCo, GDS Investment Company, GDS Beijing and GDS Shanghai and their subsidiaries respectively. Other management members of GDS and board appointee serve as directors and officers of Management HoldCo., GDS Investment Company, GDS Beijing and GDS Shanghai and their subsidiaries. F-10 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) This restructuring could reduce risk by allocating ownership of the VIEs among a larger number of individual management shareholders, and strengthen corporate governance with the establishment of the board of directors in the VIEs and its subsidiaries. This restructuring could also create a more stable ownership structure by avoiding reliance on a single or small number of natural persons, and by buffering the ownership of the VIEs with an additional layer of legal entities, creating an institutional structure that is tied to the Company’s management philosophy and culture. VIE Agreements were entered into among GDS Beijing, GDS Shanghai, Management HoldCo, its shareholders and GDS Investment Company. The following is a summary of the contractual VIE Agreements entered among GDS Investment Company, GDS Beijing, GDS Shanghai, Management HoldCo and its shareholders. Equity Interest Pledge Agreements. Pursuant to the equity interest pledge agreements, each shareholder of Management HoldCo has pledged all of his or her equity interest in Management HoldCo as a continuing first priority security interest in favor of GDS Investment Company, as applicable, to respectively guarantee Management HoldCo’s and its shareholders’ performance of their obligations under the relevant contractual arrangement, and Management HoldCo has pledged all of its equity interest in GDS Beijing and GDS Shanghai as a continuing first priority security interest in favor of GDS Investment Company, as applicable, to respectively guarantee their performance of their obligations under the relevant contractual arrangement, which include the exclusive technology license and service agreement, loan agreement, exclusive call option agreement, and shareholder voting rights proxy agreement, and intellectual property rights license agreement. If GDS Beijing or GDS Shanghai or Management HoldCo or any of its shareholders breaches their contractual obligations under these agreements, GDS Investment Company, as pledgee, will be entitled to certain rights regarding the pledged equity interests, including receiving proceeds from the auction or sale of all or part of the pledged equity interests of Management HoldCo, GDS Beijing and GDS Shanghai in accordance with PRC law. Management HoldCo and each of its shareholders agrees that, during the term of the equity interest pledge agreements, it or he or she will not dispose of the pledged equity interests or create or allow creation of any encumbrance on the pledged equity interests without the prior written consent of GDS Investment Company. The equity interest pledge agreements remain effective until GDS Beijing and GDS Shanghai and Management HoldCo and its shareholders discharge all their obligations under the contractual arrangements. The equity pledge has been registered by Management HoldCo, GDS Beijing and GDS Shanghai in favor of GDS Investment Company with the relevant office of the Administration for Market Regulation in accordance with the PRC Property Rights Law. Shareholder Voting Rights Proxy Agreements. Pursuant to the shareholder voting rights proxy agreements, each of GDS Beijing, GDS Shanghai, Management HoldCo and each of its shareholders has irrevocably appointed the PRC citizen(s) as designated by GDS Investment Company to act as GDS Beijing’s, GDS Shanghai’s, Management HoldCo’s and its such shareholder’s exclusive attorney-in-fact to exercise all shareholder rights, including, but not limited to, voting on all matters of Management HoldCo, GDS Beijing, GDS Beijing’s subsidiaries and GDS Shanghai requiring shareholder approval, and appointing directors and executive officers. GDS Investment Company is also entitled to change the appointment by designating another PRC citizen(s) to act as exclusive attorney-in-fact of GDS Beijing, GDS Shanghai, Management HoldCo and its shareholders with prior notice to Management HoldCo or its such shareholders. Each shareholder voting rights proxy agreement will remain in force for so long as Management HoldCo remains a shareholder of GDS Beijing or GDS Shanghai and the shareholder remains a shareholder of Management HoldCo, as applicable. Exclusive Technology License and Service Agreements.

Loan Agreements. Pursuant to the loan agreements between GDS Investment Company and Management HoldCo or its shareholders, GDS Investment Company has agreed to extend loans in an aggregate amount of RMB310,100 to Management HoldCo solely for the capitalization of GDS Beijing and GDS Shanghai and RMB1,000 to the shareholders of Management HoldCo solely for the capitalization of Management HoldCo. Pursuant to the loan agreements, GDS Investment Company has the right to require repayment of the loans upon delivery of thirty- day’s prior notice to Management HoldCo or its shareholders, as applicable, and Management HoldCo or its shareholders can repay the loans by either sale of their equity interests in GDS Beijing and GDS Shanghai or Management HoldCo, as applicable, to GDS Investment Company or its designated person(s) pursuant to their respective exclusive call option agreements, or other methods as determined by GDS Investment Company pursuant to its articles of association and the applicable PRC laws and regulations. Under the terms of the VIE Agreements, the Company has (i) the right to receive service fees on a yearly basis at an amount equivalent to all of the net profits of the VIEs under the exclusive technology license and services agreements when such services are provided; (ii) the right to receive all dividends declared by the VIEs and the right to all undistributed earnings of the VIEs; (iii) the right to receive the residual benefits of the VIEs through its exclusive option to acquire 100% of the equity interests in the VIEs, to the extent permitted under PRC law; and (iv) the right to require each of the shareholder of the VIEs to appoint the PRC citizen(s) as designated by GDS Investment Company to act as such shareholder’s exclusive attorney-in-fact to exercise all shareholder rights, including, but not limited to, voting on all matters of the VIEs requiring shareholder approval, disposing of all or part of the shareholder’s equity interest in the VIEs, and appointing directors and executive officers. In accordance with Accounting Standards Codification (“ASC”) 810-10-25-38A, the Company has a controlling financial interest in the VIEs because the Company has (i) the power to direct activities of the VIEs that most significantly impact the economic performance of the VIEs; and (ii) the obligation to absorb the expected losses and the right to receive expected residual return of the VIEs that could potentially be significant to the VIEs. The terms of the VIE Agreements and the Company’s financial support to the VIEs were considered in determining that the Company is the primary beneficiary of the VIEs. Accordingly, the financial statements of the VIEs are consolidated in the Company’s consolidated financial statements. Under the terms of the VIE Agreements, the VIEs’ equity holders have no rights to the net assets nor have the obligations to fund the deficit, and such rights and obligations have been vested to the Company. All of the equity (net assets) or deficits (net liabilities) and net income (loss) of the VIEs are attributed to the Company. F-12 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) The Company has been advised by its PRC legal counsel that each of the VIE agreements is valid, binding and enforceable in accordance with its terms and applicable PRC laws and the ownership structure of the VIEs does not violate applicable PRC Laws. However, there are substantial uncertainties regarding the interpretation and application of PRC laws and future PRC laws and regulations. There can be no assurance that the PRC authorities will take a view that is not contrary to or otherwise different. If the current ownership structure of the Company and the VIE Agreements are determined to be in violation of any existing or future PRC laws and regulations, the PRC government could: Levy fines on the Company or confiscate income of the Company; Revoke or suspend the VIEs' business or operating licenses; Discontinue or place restrictions or onerous conditions on VIE's operations; Require the Company to discontinue their operations in the PRC; Require the Company to undergo a costly and disruptive restructuring; Take other regulatory or enforcement actions that could be harmful to the Company's business. The imposition of any of these government actions could result in the termination of the VIE agreements, which would result in the Company losing the (i) ability to direct the activities of the VIEs and (ii) rights to receive substantially all the economic benefits and residual returns from the VIEs and thus result in the deconsolidation of the VIEs in the Company’s consolidated financial statements. The assets and liabilities of VIEs are presented parenthetically on the face of the consolidated balance sheets, except for the exclusion of bank borrowings of VIEs totaling RMB1,444,176 and RMB1,562,198, net of debt issuance cost, as of December 31, 2018 and 2019, respectively, that are guaranteed by GDS Holdings. Accounts receivable and property and equipment of VIEs with carrying amounts of RMB83,468 and RMB114,344, respectively, as of December 31, 2019 that were pledged solely to secure banking borrowings of VIEs. As of December 31, 2018, RMB78,556 and RMB335,708 of accounts receivable and property and equipment respectively of VIEs were pledged solely to secure banking borrowings of VIEs. Net revenue, net income, operating, investing and financing cash flows of the VIEs that were included in the Company’s consolidated financial statements for the years ended December 31, 2017, 2018 and 2019 are as follows: Years ended December 31, 2018 2017 2019 Net revenue Net income (loss) Net cash provided by operating activities Net cash used in investing activities Net cash (used in) provided by financing activities 1,469,929 44,541 186,843 (286,476) (7,417) 2,712,875 (59,757) 739,848 (1,063,826) 614,575 4,013,561 99,857 414,424 (201,995) (43,547) The unrecognized revenue producing assets that are held by the VIEs comprise of internally developed software, intellectual property and trademarks which were not recorded on the Company’s consolidated balance sheets as they do not meet all the capitalization criteria. F-13 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) Costs recognized by the VIEs for outsourcing and other services provided by other entities within the Company were RMB658,617, RMB1,260,481 and RMB2,017,032 for the years ended December 31, 2017, 2018 and 2019, respectively, net of the services provided to other entities within the Company. These inter-company transactions are eliminated in the consolidated financial statements. (b) Use of estimates The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include, but are not limited to, the useful lives of long-lived assets, the fair values of assets acquired and liabilities assumed and the consideration transferred in a business combination, the fair value of the reporting unit for the goodwill impairment test, the allowance for doubtful accounts receivable, the valuation of derivatives, the realization of deferred income tax assets, the fair value of share-based compensation awards, the recoverability of long-lived assets, valuation of right-of-use assets and the fair value of the asset retirement obligation. Changes in facts and circumstances may result in revised estimates. Actual results could differ from those estimates, and as such, differences may be material to the consolidated financial statements. (c) Cash and cash equivalents The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. The Company does not have any cash equivalents as of December 31, 2018 and 2019. (d) Restricted cash Restricted cash represents amounts held by banks, which are not available for the Company’s use, as security for bank borrowings and related interests. Upon repayment of bank borrowings and the related interests, the deposits are released by the bank and available for general use by the Company. (e) Fair value of financial instruments The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels (note 16 to the consolidated financial statements): Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. Level 2 Inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. F-14 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) (f) Contract balances The timing of revenue recognition, billings and cash collections result in accounts receivable, contract assets and contract liabilities (i.e. deferred revenue). Accounts receivable are recorded at the invoice amount, net of an allowance for doubtful account and is recognized in the period when the Company has transferred products or provided services to its customers and when its right to consideration is unconditional. Amounts collected on accounts receivable are included in net cash provided by operating activities in the consolidated statements of cash flows. The Company maintains an allowance for doubtful accounts for estimated losses inherent in its accounts receivable portfolio. In establishing the required allowance, management considers historical losses adjusted to take into account current market conditions and customers’ financial condition, the amount of receivables in dispute, the accounts receivable aging, and the customers’ repayment patterns. The Company reviews its allowance for doubtful accounts on a customer-by-customer basis. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance- sheet credit exposure related to its customers. A contract asset exists when the Company has transferred products or provided services to its customers but customer payment is contingent upon satisfaction of additional performance obligations. Contract assets are recorded in other current assets and other assets in the consolidated balance sheet. Deferred revenue (a contract liability) is recognized when the Company has an unconditional right to a payment before it transfers goods or services to customers. (g) Equity Method Investments The Company’s investments in entities in which the Company can exercise significant influence but does not own a majority equity interest or control are generally accounted for under the equity method of accounting, as the Company concluded it does not have control, but has the ability to exercise significant influence over the investees. Equity method investments are initially measured at cost, and are subsequently adjusted for cash contributions, distributions and the Company's share of the income and losses of the investees. The Company records its equity method investment in other non-current assets in the consolidated balance sheet. The Company's proportionate share of the income or loss from its equity method investment are recorded in others, net in the consolidated statement of operations. The Company reviews its investment periodically to determine if any investment may be impaired considering both qualitative and quantitative factors that may have a significant impact on the investees' fair value. The Company did not record any impairment charges related to its equity method investment for the year ended December 31, 2019. Equity method investment is recorded in other non-current assets on the consolidated balance sheets. The Company’s share of the earnings or losses of equity method investee are recorded in others, net on the consolidated statements of operations. (h) Property and equipment Property and equipment are carried at cost less accumulated depreciation and any recorded impairment. Property and equipment acquired under finance leases are initially recorded at the present value of minimum lease payments. Gains or losses arising from the disposal of an item of property and equipment are determined based on the difference between the net disposal proceeds and the carrying amount of the item and are recognized in profit or loss on the date of disposal. F-15 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) The estimated useful lives are presented below. Land Buildings Data center equipment – Machinery – Other equipment Leasehold improvement Furniture and office equipment Vehicles Remaining lease terms Shorter of the lease term and 30 years 10 - 20 years 3 - 5 years Shorter of the lease term and the estimated useful lives of the assets 3 - 5 years 5 years Construction in progress primarily consists of the cost of data center buildings and the related construction expenditures that are required to prepare the data center buildings for their intended use. No depreciation is provided in respect of construction in progress until it is substantially completed and ready for its intended use. Once a data center building is ready for its intended use and becomes operational, construction in progress is transferred to the respective category of property and equipment and is depreciated over the estimated useful life of the underlying assets. Depreciation on property and equipment is calculated on the straight-line method over the estimated useful lives of the assets. For assets acquired under a finance lease, the assets are amortized in a manner consistent with the Company’s normal depreciation policy for owned assets if the lease transfers ownership to the Company by the end of the lease term or contains a bargain- purchase-option. Otherwise, assets acquired under a finance lease are amortized over the lease term. (i) Long-lived assets held for sale Long-lived assets are classified as held-for-sale if: (1) the Company has committed to a plan to sell the assets that are available for sale in its present condition, including initiating actions to complete the sale that is probable to qualify for as a completed sale within one year; (2) it is unlikely that significant changes to the plan will be made or the plan will be withdrawn; (3) the assets are being marketed for sale at a price that is reasonable in related to its current value. Long-lived assets held for sale are recorded at the lower of carrying value and fair value less cost to sell. A loss shall be recognized for any initial or subsequent write-down to fair-value less cost to sell. Long-lived assets held for sale are not depreciated while classified as held for sale. (j) Leases The Company is a lessee in several non-cancellable operating leases and finance leases, primarily for data centers, lands, offices and other equipment. The Company adopted ASC 842 on January 1, 2019, using a modified retrospective method. Accounting for leases before adoption of ASC 842, Leases Before adoption of ASC 842, the Company accounted for leases in accordance with ASC 840, Leases, according to which, leases were classified at the lease inception date as either a capital lease or an operating lease. A lease was a capital lease if any of the following conditions existed: a) ownership is transferred to the lessee by the end of the lease term, b) there is a bargain purchase option, c) the lease term is at least 75% of the property’s estimated remaining economic life, or d) the present value of the minimum lease payments at the beginning of the lease term is 90% or more of the fair value of the leased property to the lessor at the inception date. The Company recorded a capital lease as an asset and an obligation at an amount equal to the present value at the beginning of the lease term of minimum lease payments during the lease term. If at any time the lessee and lessor agree to change the provisions of the lease, other than by renewing the lease or extending its term, in a manner that would have resulted in a different classification of the lease under the lease classification criteria had the changed terms been in effect at lease inception, the revised agreement was considered as a new agreement over its term, and the lease classification criteria was applied for purposes of classifying the new lease. F-16 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) The Company recorded an asset and related financing obligation for the estimated construction costs under build-to-suit lease arrangements where it was considered the owner for accounting purposes, to the extent the Company was involved in the construction of the building or structural improvements or had construction risk prior to commencement of a lease. Upon completion of the construction and commencement of the lease terms, the Company assessed whether these arrangements qualify for sales recognition under the deemed sale-leaseback transaction. If the arrangements did not qualify for sales recognition under the sale-leaseback accounting guidance, the Company continued to be the deemed owner of the build-to-suit assets for financial reporting purposes. The Company kept the construction costs of the assets on its balance sheet. In addition, lease payments less the portion considered to be interest expense decreased the financing liability. Rental costs on operating leases were charged to expense on a straight-line basis over the lease term. Certain operating leases contain rent holidays and escalating rent. Rent holidays and escalating rent were considered in determining the straight-line rent expense to be recorded over the lease term. Rental costs associated with building operating leases that were incurred during the construction of leasehold improvements and to otherwise ready the property for the Company’s intended use were recognized as rental expenses and were not capitalized. Accounting for leases after adoption of ASC 842, Leases The Company determines if an arrangement is or contains a lease at its inception. The Company recognizes lease liabilities and right-of-use (“ROU”) assets at lease commencement date. Lease liabilities are initially and subsequently measured at the present value of unpaid lease payments at the lease commencement date and is subsequently measured at amortized cost using the effective-interest method. Since most of the Company's leases do not provide an implicit rate, the Company uses its own incremental borrowing rate on a collateralized basis in determining the present value of unpaid lease payments. ROU assets are initially measured at cost, which consist of (i) initial measurement of the lease liability; (ii) lease payments made to the lessor at or before the commencement date less any lease incentives received; and (iii) initial direct costs incurred by the Company. Variable lease payments are excluded from the measurement of ROU assets and lease liabilities and are recognized in the period in which the obligation for those payments is incurred. For operating leases, the Company recognizes a single lease cost on a straight-line basis over the remaining lease term. For finance leases, the ROU assets are subsequently amortized using the straight-line method from the lease commencement date to the earlier of the end of its useful life or the end of the lease term. Amortization of the ROU assets are recognized and presented separately from interest expense on the lease liability. ROU assets for operating and finance leases are periodically reduced by impairment losses. The Company uses the long-lived assets impairment guidance in ASC Subtopic 360-10, Property, Plant, and Equipment—Overall, to determine whether a ROU asset is impaired, and if so, the amount of the impairment loss to recognize. Prior to the adoption of ASC 842, prepayment for land use rights are presented as prepaid land use rights on the consolidated balance sheet and are measured at cost and subsequently amortized using the straight-line method. Upon the adoption of ASC 842 on January 1, 2019, land use rights acquired are assessed in accordance with ASC 842 and recognized in operating lease right-of- use assets if they meet the definition of operating lease, or property and equipment if they meet the definition of finance lease. The Company has elected not to recognize ROU assets and lease liabilities for short-term leases (i.e. leases that, at the commencement date, have a lease term of 12 months or less and do not include an option to purchase the underlying asset that the lessee is reasonably certain to exercise). F-17 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) The Company records an asset and related financing obligation for the estimated construction costs under build-to-suit lease arrangements where it controls the asset during construction. Upon completion of the construction and commencement of the lease terms, the Company assesses whether these arrangements qualify for sales recognition under the deemed sale-leaseback transaction. If the arrangements do not qualify for sales recognition under the sale-leaseback accounting guidance, the Company continues to be the deemed owner of the build-to-suit assets for financial reporting purposes. The Company keeps the construction costs of the assets on its balance sheet. In addition, lease payments less the portion considered to be interest expense decrease the financing liability. If a lease is modified and that modification is not accounted for as a separate contract, the classification of the lease is reassessed as of the effective date of the modification based on its modified terms and conditions and the facts and circumstances as of that date. (k) Asset retirement costs The Company’s asset retirement obligations are primarily related to its data center buildings, of which the majority are leased under long-term arrangements, and, in certain cases, are required to be returned to the landlords in their original condition. The fair value of a liability for an asset retirement obligation is recognized in the period in which it is incurred. The corresponding asset retirement costs are capitalized as part of the cost of leasehold improvements and are depreciated over the shorter of the asset or the term of the lease subsequent to the initial measurement. The Company accretes the liability in relation to the asset retirement obligations over time and the accretion expense is recorded in cost of revenue. Asset retirement obligations are recorded in other long-term liabilities. The following table summarizes the activity of the asset retirement obligation liability: Asset retirement obligations as of January 1, 2017 Additions Accretion expense Asset retirement obligations as of December 31, 2017 Additions Accretion expense Asset retirement obligations as of December 31, 2018 Additions Accretion expense Asset retirement obligations as of December 31, 2019 (l) Intangible assets Intangible assets acquired in the acquisitions comprised of customer relationships and licenses. The weighted-average amortization period by major intangible asset class is as follows: Customer relationships Licenses 9,305 7,394 949 17,648 16,391 1,840 35,879 13,572 2,990 52,441 5-15 years 20 years Customer relationships represent the orders, backlog and customer lists, which arise from contractual rights or through means other than contracts. Customer relationships are amortized using a straight-line method, as the pattern in which the economic benefits of the intangible assets are consumed or used up cannot be reliably determined. Licenses are amortized using a straight-line method over the estimated beneficial period. F-18 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) The intangible assets before January 1, 2019 also include favorable leases acquired in the acquisitions with weighted-average amortization period of 13 to 20 years. Favorable lease was recognized as an intangible asset if the terms of the acquiree’s operating lease were favorable relative to market terms. Favorable lease was amortized on a straight-line method over the lease term. Upon adoption of ASC 842, Leases on January 1, 2019, favorable leases were reclassified to operating lease ROU assets. (m) Prepaid land use rights The land use rights represent the amounts paid and relevant costs incurred for the rights to use land in the PRC and Hong Kong SAR acquired before the adoption of ASC 842, and are carried at cost less accumulated amortization. Amortization is provided on a straight-line basis over the remaining terms of the land use right ranging from 27 to 42 years. (n) Goodwill Goodwill is an asset representing the future economic benefits arising from other assets acquired in the acquisition that are not individually identified and separately recognized. Goodwill is not amortized but is tested for impairment annually or more frequently if events or changes in circumstances indicate that it might be impaired. Goodwill is tested for impairment at the reporting unit level on an annual basis and between annual tests if an event occurs or circumstances change that would more-likely-than-not reduce the fair value of a reporting unit below its carrying value. These events or circumstances could include a significant change in the stock prices, business climate, legal factors, operating performance indicators, competition, or sale or disposition of a significant portion of a reporting unit. Application of the goodwill impairment test requires judgment, including the identification of the reporting unit, assignment of assets and liabilities to the reporting unit, assignment of goodwill to the reporting unit, and determination of the fair value of each reporting unit. The Company has the option to perform a qualitative assessment to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying value prior to performing the two-step goodwill impairment test. If it is more- likely-than-not that the fair value of a reporting unit is greater than its carrying amount, the two-step goodwill impairment test is not required. If the two-step goodwill impairment test is required, first, the fair value of the reporting unit is compared with its carrying amount (including goodwill). If the fair value of the reporting unit is less than its carrying amount, an indication of goodwill impairment exists for the reporting unit and the Company performs step two of the impairment test (measurement). Under step two, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation and the residual fair value after this allocation is the implied fair value of the reporting unit goodwill. No impairment losses were recorded for goodwill for the years ended December 31, 2017, 2018 and 2019. (o) Impairment of long-lived assets Long-lived assets (primarily including property and equipment, operating lease right-of-use assets and prepaid land use rights) are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, the Company first compares undiscounted cash flows generated by that asset or asset group to its carrying amount. If the carrying amount of the long-lived assets or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying amount exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary. No impairment losses were recorded for long-lived assets for the years ended December 31, 2017, 2018 and 2019. F-19 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) (p) Value-added-tax (“VAT”) Entities that are VAT general taxpayers are permitted to offset qualified input VAT paid to suppliers against their output VAT upon receipt of appropriate supplier VAT invoices on an entity by entity basis. When the output VAT exceeds the input VAT, the difference is remitted to tax authorities, usually on a monthly basis; whereas when the input VAT exceeds the output VAT, the difference is treated as VAT recoverable which can be carried forward indefinitely to offset future net VAT payables. VAT related to purchases and sales which have not been settled at the balance sheet date is disclosed separately as an asset and liability, respectively, in the consolidated balance sheets. As of December 31, 2018 and 2019, the Company recorded a VAT recoverable of RMB163,476 and RMB129,994 in current assets, and RMB488,526 and RMB888,483 in non-current assets, respectively. The Company also recorded VAT payables of RMB11,350 and RMB7,886 in accrued expenses and other payables, in the consolidated balance sheets as of December 31, 2018 and 2019, respectively. (q) Derivative financial instruments Derivative financial instruments are recognized initially at fair value. At the end of each reporting period, the fair value is remeasured. The gain or loss on remeasurement to fair value is recognized immediately in profit or loss. The Company entered into interest rate swap and foreign currency forward contracts primarily for the purpose to manage the interest rate and foreign exchange risk for the long-term borrowings. The Company has elected not to apply hedge accounting to these derivative instruments and recognized all derivatives on the Company's consolidated balance sheets at fair value. The Company estimates the fair value of its interest rate swap and foreign currency forward contracts using a pricing model based on market observable inputs. Fair value gains or losses associated with interest rate swap and foreign currency forward contracts are recorded within interest expenses and foreign exchange gain/(loss) in the Company’s consolidated statements of operations. Cash received or paid for realized gains or losses associated with interest rate swap and foreign currency forward contracts are included in operating cash flows in the consolidated statements of cash flows. For further information on derivative financial instruments, see Note 15 below. (r) Commitment and contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines, and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred. (s) Revenue recognition The Company adopted ASC 606 Revenue from Contracts with Customers on January 1, 2018. The Company applied ASC 606 using the cumulative effect method – i.e. by recognizing the cumulative effect of initially applying ASC 606 as an adjustment to the opening balance of accumulated deficit at January 1, 2018. The Company elects to apply this guidance retrospectively only to contracts that are not completed contracts as of January 1, 2018. The Company recognizes revenue as the Company satisfies a performance obligation by transferring control over a good or service to a customer. For each performance obligation satisfied over time, the Company recognizes revenue over time by measuring the progress toward complete satisfaction of that performance obligation. If the Company does not satisfy a performance obligation over time, the performance obligation is satisfied at a point in time. Revenue is measured as the amount of consideration to which the Company expects to be entitled in exchange for transferring promised goods or services to a customer, excluding amounts collected on behalf of third parties. F-20 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) For contracts with customers that contain multiple performance obligations, the Company accounts for individual performance obligations separately if they are distinct or as a series of distinct obligations if the individual performance obligations meet the series criteria. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. The transaction price is allocated to the separate performance obligation on a relative standalone selling price basis. The standalone selling price is determined based on overall pricing objectives, taking into consideration market conditions, geographic locations and other factors. The Company derives revenue primarily from the delivery of (i) colocation services; and (ii) managed services, including managed hosting services and managed cloud services. The remainder of the Company’s revenue is from IT equipment sales that are either sold on a stand-alone basis or bundled in a managed service contract arrangement and consulting services. Colocation services are services where the Company provides space, power and cooling to customers for housing and operating their IT system equipment in the Company’s data centers. Managed hosting services are services where the Company provides outsourced services to manage the customers’ data center operations, including data migration, IT operations, security and data storage. Managed cloud services are services where the Company offers direct private connection to major cloud platforms, an innovative service platform for managing hybrid clouds and, where required, the resale of public cloud services. Certain contracts with customers for colocation services and managed services provide for variable considerations that are primarily based on the usage of such services. Revenues on such contracts are recognized based on the agreed usage-based fees as the actual services are rendered throughout the contract term. Certain contracts with remaining customers provide for a fixed consideration over the contract service period. Revenue on such contracts are recognized on a straight-line basis over the term of the contract. In certain colocation and managed hosting service contracts, the Company agrees to charge customers for their actual power consumption. Relevant revenue is recognized based on actual power consumption during each period. In certain other colocation and managed hosting service contracts, the Company specifies a fixed power consumption limit each month for customers. If a customer’s actual power consumption is below the limit, no additional fee is charged. If the actual power consumption is above the limit, the Company charges the customer additional power consumption fees calculated based on the portion of actual power consumption exceeding the limit, multiplied by a fixed unit price, which is determined based on market price, without providing the customer with any rights to acquire additional goods or services. Accordingly, relevant revenue is recognized each month based on actual additional power consumption fees. The Company’s colocation service and managed service contracts with customers contain both lease and nonlease components. The Company elected to adopt the practical expedient which allows lessors to combine lease and non-lease components and account for them as one component if i) they have the same timing and pattern of transfer; and ii) the lease component, if accounted for separately, would be classified as an operating lease. The Company elected to apply the practical expedient on the contracts that meet the conditions. In addition, the Company has performed a qualitative analysis to determine that the non-lease component is the predominant component of its revenue stream as the customer would ascribe more value to the services provided rather than to the lease component. Therefore, the combined component is accounted for in accordance with the current revenue accounting guidance (“Topic 606”). For contracts that do not meet the conditions required to adopt the practical expedient, the lease component is accounted for in accordance with the current lease accounting guidance (“Topic 842”), which is immaterial for the year ended December 31, 2019. The Company has elected to apply the practical expedient on a prospective basis. Revenue recognized for colocation or managed hosting and cloud services delivered prior to billing is recorded within accounts receivable. The Company generally bills the customer on a monthly or quarterly basis in arrears. Cash received in advance from customers prior to the delivery of the colocation or managed hosting and cloud services is recorded as deferred revenue. F-21 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) The sale of IT equipment is recognized when the customer obtains control of the equipment, which is typically when delivery has occurred, the customer accepts the equipment and the Company has no performance obligation after the delivery. In certain managed service contracts, the Company sells and delivers IT equipment such as servers and computer terminals prior to the delivery of the services. Since sale of equipment can be distinguished and is separately identifiable from other promises in the contract and it is distinct within the context of the contract, the sale of equipment is considered a separate performance obligation. Accordingly, the contract consideration is allocated to the equipment and the managed services based on their relative standalone selling prices. Consulting services are provided to customers for a fixed amount over the service period, usually less than one year. The Company recognizes revenues from consulting services over the period when the services were provided, since customers simultaneously receive and consume the benefit of the services. The Company uses the input method based on the pattern of service provided to the customers. Revenue is generally recognized on a gross basis as the Company is primarily responsible for fulfilling the contract, assumes inventory risk and has discretion in establishing the price when selling to the customer. To the extent the Company does not meet the criteria for recognizing revenue on a gross basis, the Company records the revenue on a net basis. (t) Cost of revenues Cost of revenues consists primarily of utility costs, depreciation of property and equipment, rental costs, labor costs and other costs directly attributable to the provision of the service revenue. (u) Research and development and advertising costs Research and development and advertising costs are expensed as incurred. Research and development costs amounted to RMB7,261, RMB13,915 and RMB21,627 in 2017, 2018 and 2019, respectively. Research and development costs consist primarily of payroll and related personnel costs for developing or significantly improving the Company’s services and products. Advertising costs amounted to RMB10,189, RMB6,332 and RMB7,454 in 2017, 2018 and 2019, respectively. (v) Government grants Government grants are recognized when received and when all the conditions for their receipt have been met. Subsidies that compensate the Company for expenses incurred are recognized as a reduction of expenses in the consolidated statements of operations. Subsidies that are not associated with expenses are recognized as other income. Subsidies for the acquisition of property and equipment are recorded as a liability until earned and then depreciated over the useful life of the related assets as a reduction of the depreciation charges. Subsidies for obtaining the rights to use land are recorded as a liability until earned and then amortized over the land use right period as a reduction of the amortization charges of the related land use rights. In 2010 and 2011, the Company received government subsidies that required the Company to operate in a particular area for a certain period. The Company recorded the subsidies in other long-term liabilities when the subsidies were received and subsequently recognized as government subsidy income ratably over the period the Company is required to operate in the area. In 2017, the Company received government subsidies that required the Company to pass certain inspection on the related project . The Company recorded such subsidies in other long-term liabilities when received , which are reclassified to accrued expenses and other payables when the inspection is expected to be completed within one year, and will be recorded as government subsidy income when the conditions are met. As of December 31, 2018 and 2019, deferred government grants of RMB9,771 and RMB6,507 are recorded in other long-term liabilities, respectively. Deferred government grants of RMB4,800 and RMB6,003 are recorded in accrued expenses and other payables in the consolidated balance sheets as of December 31,2018 and 2019, respectively. F-22 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) (w) Capitalized interest A reconciliation of total interest costs to “Interest expenses” as reported in the consolidated statements of operations for 2017, 2018 and 2019 is as follows: Years ended December 31, 2018 2019 2017 Total interest costs Less: interest costs capitalized Interest expenses 466,460 749,730 (54,457) (93,544) 1,040,898 (72,205) 412,003 656,186 968,693 Interest costs that are directly attributable to the construction of an asset which necessarily takes a substantial period of time to get ready for its intended use or sale are capitalized as part of the cost of that asset. The capitalization of interest costs as part of the cost of a qualifying asset commences when expenditure for the asset is being incurred, interest costs are being incurred and activities that are necessary to prepare the asset for its intended use or sale are in progress. Capitalization of interest costs is ceased when the asset is substantially complete and ready for its intended use. (x) Debt issuance costs Debt issuance costs are capitalized and are amortized over the life of the related debts based on the effective interest method. Such amortization is included as a component of interest expense. Unamortised debt issuance costs of RMB203,779 and RMB273,822 are presented as a reduction of debt as of December 31, 2018 and 2019, respectively. (y) Income tax Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for deferred tax assets for which it is more likely than not that the related tax benefits will not be realized. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company records interest related to unrecognized tax benefits in interest expense and penalties in general and administrative expenses. (z) Share-based compensation The Company accounts for the compensation cost from share-based payment transactions with employees based on the grant-date fair value of the equity instrument issued. The grant-date fair value of the award is recognized as compensation expense, net of forfeitures, over the period during which an employee is required to provide service in exchange for the award, which is generally the vesting period. When no future services are required to be performed by the employee in exchange for an award of equity instruments, and if such award does not contain a performance or market condition, the cost of the award is expensed on the grant date. The Company recognizes compensation cost for an award with only service conditions that has a graded vesting schedule on a straight-line basis over the requisite service period for the entire award, provided that the cumulative amount of compensation cost recognized at any date at least equals the portion of the grant-date value of such award that is vested at that date. F-23 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) Awards granted to employees with performance conditions attached are measured at fair value on the grant date and are recognized as the compensation expenses in the period and thereafter when the performance goal becomes probable to achieve. Awards granted to employees with market conditions attached are measured at fair value on the grant date and are recognized as the compensation expenses over the estimated requisite service period, regardless of whether the market condition has been satisfied if the requisite service period is fulfilled. The Company recognizes the estimated compensation cost of service-based restricted share based on the fair value of its ordinary shares on the date of the grant. The Company recognizes the compensation cost, net of forfeitures, over its respective vesting term. The Company recognizes the estimated compensation cost of performance-based restricted share based on the fair value of its ordinary shares on the date of the grant. The rewards are earned upon attainment of identified performance goals. The Company recognizes the compensation cost, net of forfeitures, over the performance period. The Company also adjusts the compensation cost based on the probability of performance goal achievement at the end of each reporting period. The Company accounts for forfeitures when they occur. Compensation cost previously recognized are reversed in the period the award is forfeited, for an award that is forfeited before completion of the requisite service period. Share-based payment transactions with nonemployees in which goods or services are received in exchange for equity instruments are accounted for based on the fair value of the consideration received or the fair value of the equity instrument issued, whichever is more reliably measurable. The measurement date of the fair value of the equity instrument issued is the earlier of either the date on which the counterparty’s performance is complete or the date at which a commitment for performance by the counterparty to earn the equity instrument is reached. For further information on share-based compensation, see Note 18 below. (aa) Employee benefits Pursuant to relevant PRC regulations, the Company is required to make contributions to various defined contribution plans organized by municipal and provincial PRC governments. The contributions are made for each PRC employee at rates ranging from 28% to 49% on a standard salary base as determined by local social security bureau. Contributions to the defined contribution plans are charged to the consolidated statements of operations when the related service is provided. (bb) Foreign currency translation and foreign currency risks The functional currency of GDS Holdings is the USD, whereas the functional currency of its subsidiaries and consolidated VIEs in PRC, subsidiaries in Hong Kong SAR and subsidiaries in Singapore is the RMB, Hong Kong dollar (“HKD”) and Singapore dollar (“SGD”), respectively. The reporting currency of the Company is RMB as the major operations of the Company are within the PRC. Transactions denominated in currencies other than the functional currency are re-measured into the functional currency at the exchange rates prevailing on the transaction dates. Monetary assets and liabilities denominated in foreign currencies are re- measured at the exchange rates prevailing at the balance sheet dates. Non-monetary items that are measured in terms of historical costs in foreign currency are re-measured using the exchange rates at the dates of the initial transactions. Exchange gains and losses are recognized in profit or loss and are reported in foreign currency exchange gain (loss) on a net basis. The results of foreign operations are translated into RMB at the exchange rates as of the balance sheet date for assets and liabilities, the average daily exchange rate for each month for income and expense items and the historical exchange rates for equity accounts. Translation gains and losses are recorded in other comprehensive income and accumulated in the translation adjustment component of equity until the sale or liquidation of the foreign entity. F-24 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) The RMB is not a freely convertible currency. The PRC State Administration for Foreign Exchange, under the authority of the PRC government, controls the conversion of RMB to foreign currencies. The value of the RMB is subject to changes of central government policies and international economic and political developments affecting supply and demand in the China foreign exchange trading system market. The Company’s cash and restricted cash denominated in RMB amounted to RMB1,134,694 and RMB2,119,758 as of December 31, 2018 and 2019, respectively. As of December 31, 2019, the Company’s cash and restricted cash were deposited in major financial institutions located in PRC, Hong Kong SAR, US and Singapore, and were denominated in the following currencies: In PRC In Hong Kong SAR In US In Singapore Total in original currency RMB equivalent (cc) Concentration of credit risk JPY USD — HKD 205,827 RMB 2,096,453 23,305 — — 2,119,758 2,119,758 3,634,318 215,312 — 46,973 240,357 27,547 — — 520,959 240,357 27,547 1,765 257,227 10,932 — — EUR SGD — — — 153 — — 176 — 176 153 909 1,200 Financial instruments that potentially expose the Company to concentrations of credit risk consist principally of cash and cash equivalent, restricted cash, and accounts receivable. The Company’s investment policy requires cash and cash equivalents and restricted cash to be placed with high-quality financial institutions and to limit the amount of credit risk from any one issuer. The Company regularly evaluates the credit standing of the counterparties or financial institutions. The Company conducts credit evaluations on its customers prior to delivery of goods or services. The assessment of customer creditworthiness is primarily based on historical collection records, research of publicly available information and customer on- site visits by senior management. Based on this analysis, the Company determines what credit terms, if any, to offer to each customer individually. If the assessment indicates a likelihood of collection risk, the Company will not deliver the services or sell the products to the customer or require the customer to pay cash, post letters of credit to secure payment or to make significant down payments. Historically, credit losses on accounts receivable have been insignificant. (dd) Earnings (loss) per share Basic earnings (loss) per ordinary share is computed by dividing net income (loss) attributable to the Company’s ordinary shareholders by the weighted average number of ordinary shares outstanding during the year using the two-class method. Under the two-class method, net income (loss) attributable to the Company’s ordinary shareholders is allocated between ordinary shares and other participating securities based on participating rights in undistributed earnings. The Company’s redeemable preferred shares (note 14) are participating securities since the holders of these securities participate in dividends on the same basis as ordinary shareholders. These participating securities are not included in the computation of basic loss per ordinary share in periods when the Company reports net loss, because these participating security holders have no obligation to share in the losses of the Company. Diluted earnings (loss) per share is calculated by dividing net income (loss) attributable to the Company’s ordinary shareholders as adjusted for the effect of dilutive ordinary share equivalents, if any, by the weighted average number of ordinary and dilutive ordinary share equivalents outstanding during the year. Ordinary share equivalents include the ordinary shares issuable upon the exercise of the outstanding share options (using the treasury stock method) and conversion of redeemable preferred shares and convertible bonds (using the as-if-converted method). Potential dilutive securities are not included in the calculation of diluted earnings (loss) per share if the impact is anti-dilutive. F-25 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) (ee) Changes in accounting principle The Company adopted ASC 842, Leases on January 1, 2019. The Company applied ASC 842 using a modified retrospective transition method on all leases existing at January 1, 2019, the date of initial application. As a result, the Company was not required to adjust its comparative period financial information for effects of the standard or make the new required lease disclosures for periods before January 1, 2019. The Company has elected the package of the transition practical expedients, including (1) not to reassess whether any expired or existing contracts, including land easements that were not previously accounted for as leases, are or contain leases, (2) not to reassess the lease classification for any expired or existing leases, and (3) not to reassess initial direct costs for any existing leases. As a practical expedient, the Company has elected that for all leases, where it is the lessee, not to separate non-lease components from lease components and instead to account for all lease and non-lease components associated with each lease as a single lease component. The Company did not elect the practical expedient to use hindsight for leases existing at the adoption date. Adoption of the standard had a significant impact on the Company's financial results, including the (1) recognition of new ROU assets and liabilities for operating leases; (2) reclassification of intangible assets for favourable leases for operating leases to ROU assets; and (3) de-recognition of other financing obligations and construction in progress for assets under construction in build-to- suit lease arrangements. The adoption of ASC 842 does not have impact to the accumulated deficit of the Company as of January 1, 2019. The impact for adoption of ASC 842 to the Company's condensed consolidated balance sheet as of January 1, 2019 is as follows: Assets Prepaid expenses Property and equipment, net Intangible assets, net Operating lease ROU assets Liabilities Accounts payable Accrued expenses and other payables Operating lease liabilities, current Operating lease liabilities, non-current Finance lease and other financing obligations, non-current Balances at Adjustments due to Balances at December 31, 2018 adoption of ASC 842 January 1, 2019 64,843 13,994,945 482,492 — 2,051 (336,719) (44,552) 513,961 66,894 13,658,226 437,940 513,961 1,508,020 476,564 — — 4,134,327 (3,864) (13,085) 67,006 416,601 (331,917) 1,504,156 463,479 67,006 416,601 3,802,410 In addition, the account caption of "Capital lease and other financing obligations" was changed to "Finance lease and other financing obligations" upon adoption of ASC 842. (ff) Recently Issued Accounting Standards In December 2019, the FASB issued ASU 2019-12, Income Tax (Topic 740), Simplifying the Accounting for Income Taxes, which simplifies accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The ASU also improves consistent application of and simplifies GAAP for other areas of Topic 740 by clarifying and amending existing guidance. For public entities, the ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted including adoption in any interim period for periods for which financial statements have not yet been issued. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements. F-26 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force), which clarifies the accounting for implementation costs incurred in a hosting arrangement that is a service contract. Capitalization of these implementation costs are accounted for under the same guidance as implementation costs incurred to develop or obtain internal-use software and recorded as a prepaid asset. These capitalized costs are to be expensed ratably over the hosting arrangement term as operating expenses, along with the service fees. The guidance is effective for periods beginning after December 15, 2019. Early adoption is allowed. The Company does not plan to early adopt this guidance and the adoption of this standard is not expected to have a significant impact on the Company's consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which changes the fair value measurement disclosure requirements of ASC 820. Under this ASU, key provisions include new, eliminated and modified disclosure requirements. The guidance is effective for periods beginning after December 15, 2019. Early adoption is allowed. The Company does not plan to early adopt this guidance and the adoption of this standard is not expected to have a significant impact on the Company's consolidated financial statements. In January 2017, FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU is to simplify the subsequent measurement of goodwill. The ASU eliminates step 2 from the goodwill impairment test and the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This ASU should be applied on a prospective basis. The amendments in this ASU are effective for the Company for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company does not plan to early adopt this guidance and the adoption of this standard is not expected to have a significant impact on the Company's consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments, and issued subsequent amendments to the initial guidance within ASU 2018-19, ASU 2019-04, ASU 2019-05, ASU 2019-11 and ASU 2020-02, collectively referred to as “ASC 326”. ASC 326 requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. ASC 326 eliminates the probable initial recognition threshold in current GAAP and, instead, reflects an entity’s current estimate of all expected credit losses. ASC 326 is effective for the Company for its fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted since fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company will adopt this ASC 326 on January 1, 2020. The adoption of this standard will result in a change of the Company’s provision policy primarily for accounts receivable, but is not expected to have a significant impact on the Company’s consolidated financial statements. F-27 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) 3 CASH AND RESTRICTED CASH A reconciliation of cash and restricted cash in the consolidated balance sheets to the amounts in the consolidated statements of cash flows is as follows: Cash Restricted cash - current assets Restricted cash - non-current assets As of December 31, 2018 2019 2,161,622 87 123,039 5,810,938 34,299 128,025 Total cash and restricted cash shown in the consolidated statements of cash flows 2,284,748 5,973,262 Restricted cash included in non-current assets was to secure the repayment of long-term bank borrowings and related interests. 4 CONTRACT BALANCES Accounts Receivable, Net Accounts receivable, net consisted of the following: Accounts receivable Less: allowance for doubtful accounts Accounts receivable, net Including: - Current portion - Non-current portion As of December 31, 2019 2018 541,355 (241) 541,114 881,177 (133) 881,044 536,842 4,272 879,962 1,082 The Company generally invoices its customers on a monthly or quarterly basis in accordance with the contract terms. Due to timing difference between the billing and revenue recognition, accounts receivable included an unbilled portion of RMB384,640 and RMB649,608 as of December 31, 2018 and 2019, respectively. As of December 31, 2018 and 2019, the accounts receivable expected to be received after one year amounted to RMB4,272 and RMB1,082 were recorded in other non-current assets in the consolidated balance sheet, respectively. Accounts receivable of RMB365,938 and RMB520,382 was pledged as security for bank loans (note 9) as of December 31, 2018 and 2019, respectively. F-28 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) An allowance for doubtful accounts is provided based on the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company assesses the collectability of accounts receivable by analyzing specific customer accounts that have known or potential doubt as to collectability. The following table presents the movement of the allowance for doubtful accounts: Years ended December 31, 2018 2019 2017 Balance at the beginning of the year Allowance made during the year Write-off during the year Balance at the end of the year — — — — — 241 — 241 241 274 (382) 133 During the years ended December 31, 2018 and 2019, the Company made an allowance on accounts receivable of RMB241 and RMB274, respectively. Management believes all other accounts receivable as of December 31, 2019 are to be collected in full. Deferred Revenue The opening and closing balances of the Company’s deferred revenue are as following: Beginning balance as of January 1, 2019 Closing balance as of December 31, 2019 Increase Deferred revenue 73,077 105,735 32,658 The difference between the opening and closing balances of the Company's deferred revenue primarily results from the timing difference between the satisfaction of the Company's performance obligation and the customer's payment. As of December 31, 2019, the deferred revenue expected to be recognized as revenue after one year amounted to RMB15,419 were recorded in other long-term liabilities in the consolidated balance sheet. The amounts of revenue recognized during the year ended December 31, 2019 and 2018 from the opening deferred revenue balance was RMB66,500 and RMB43,192, respectively. Remaining performance obligations The Company elected to apply the practical expedient that allows the Company not to disclose the remaining performance obligations for variable considerations. This includes usage-based contracts for certain colocation and managed hosting services. As of December 31, 2019, approximately RMB1,693,411 of total revenues and deferred revenues are expected to be recognized in future periods, the majority of which will be recognized over the next three years.

Accordingly, the Company kept the construction costs of the assets on its balance sheet. In addition, lease payments less the portion considered to be interest expense decrease the financing liability.

Upon completion of the construction, the Company will assess if the arrangement qualifies for sales recognition under the sale-lease back accounting guidance. As of December 31, 2019, the obligations under above lease arrangements are recognized as other financing obligations.

The dividends are 5.0% per annum of the respective preferred shares Stated Value (i.e. the subscription price of preferred shares plus any accrued dividends that are not paid on Regular Dividend Payment Date) (and shall be adjusted to an amount equal to the ordinary share dividend rate if higher). The dividend rate will increase to 7.0% per annum and further increase by 50 basis points each quarter thereafter if the Company has not redeemed all of the preferred shares outstanding as of the eighth anniversary of the Issue Date. The dividends are computed on a basis of a 360-day year and the actual number of days elapsed. Dividends may, at the option of the Company, be paid in cash only, be paid in cash or in additional preferred shares, or a combination thereof. Conversion The holders of preferred shares have the right to convert any or all of their holdings of preferred shares Stated Value into Class A Ordinary Shares based on the conversion rate then in effect. In addition, if, at any time beginning on March 15, 2022, (i) the volume-weighted average price ("VWAP") per ADS of the GDS Holdings equals or exceeds US$53.40 (adjusted as according to anti-dilution provisions) for at least 20 trading days in any period of 30 consecutive trading days and (ii) the average daily trading volume of the ADS for such 20 qualifying trading days is at least US$10,000 in the aggregate, at the Company's election, all of the preferred shares then outstanding shall be converted into a number of Class A Ordinary Shares based on the conversion rate then in effect. The initial conversion rate is corresponding to a conversion price of US$35.60 per ADS, and will be subject to adjustments for any split, subdivision, combination, consolidation, recapitalization or similar event. Liquidation preference Upon a liquidation, after satisfaction of all liabilities and obligations to creditors of the Company and before any distribution or payment shall be made to holders of ordinary shares, each holder of preferred shares shall be entitled to receive an amount per preferred share equal to the greater of: (1) the Stated Value of preferred shares plus any dividends accumulated but unpaid thereon after the immediately preceding Regular Dividend Payment Date to but excluding the date of liquidation; (2) the payment such holders would have received had such holders, immediately prior to such liquidation converted their preferred shares into Class A Ordinary Shares. Optional Redemption by the Company The preferred shares may be redeemed, in whole or in part, at any time after March 15, 2027, at the option of the Company at a redemption price per share equal to the sum of the Stated Value per preferred share to be redeemed plus an amount per share equal to accrued but unpaid dividends on such preferred shares after the immediately preceding Regular Dividend Payment Date to but excluding the date of redemption. F-46 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) Repurchase at the Option of the Holder Upon a Fundamental Change Upon the occurrence of a Fundamental Change, as defined in the share subscription agreement, each holder of preferred shares shall have the right to require the Company to repurchase all or any portion of such holder's preferred shares at a purchase price per preferred share equal to the greater of (i) the sum of (x) 100% multiplied by the Stated Value per preferred share plus (y) an amount equal to accrued but unpaid dividends on such preferred share after the immediately preceding Regular Dividend Payment Date to but excluding the date of repurchase, plus (z) solely in the event that such Fundamental Change occurs prior to the third anniversary of the Issue Date, the present value of all undeclared dividends from the date of redemption to, and including, the third anniversary of the Issue Date, in each case, discounted to the date of redemption on the basis of actual days elapsed (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, which is the yield to maturity at the time of computation of United States Treasury securities with a constant maturity, plus 50 basis points, and (ii) the amount of cash and/or other assets such holder would have received had such holder, immediately prior to the occurrence of such Fundamental Change, converted such preferred shares into Class A Ordinary Shares. Financing for Redemption of Convertible Preferred Shares In the event that any preferred shares remain outstanding from and after the tenth anniversary of the Issue Date, the holders of preferred shares constituting at least 90% of the preferred shares issued as of the Issue Date (as adjusted for any split, subdivision, combination, consolidation, recapitalization or similar event with respect to the preferred shares) shall have the right to require the Company to sell all or a portion of its business and/or to conduct other fundraising or refinancing activities, and use reasonable best efforts to consummate such sale or to issue equity or debt securities (or obtain other debt financing) in an amount sufficient to redeem in full in cash, and use best endeavors to as soon as reasonably practicable redeem in full in cash, all of the preferred shares then outstanding at a redemption price per share equal to the sum of the Stated Value per preferred share to be redeemed plus an amount per share equal to accrued but unpaid dividends on such preferred shares after the immediately preceding Regular Dividend Payment Date to but excluding the date of redemption. Voting rights The holders of the preferred shares have voting rights equivalent to the ordinary shareholders on an "if converted" basis. In addition, the Company shall not take certain actions without first obtaining the written consent or affirmative vote at a meeting called for that purpose by holders of at least 75% of the then outstanding preferred shares. The Company has classified these preferred shares as mezzanine equity in the consolidated balance sheets since they are contingently redeemable upon a Fundamental Change or include liquidation preference provisions that are not solely within the Company's control. The Company evaluated the embedded conversion, call and put options in the preferred shares to determine if they require bifurcation and are accounted for as derivatives, and concluded that there were no embedded derivatives to be bifurcated from the preferred share pursuant to ASC 815. The Company also determined that there was no BCF attributable to the preferred shares because the initial conversion price was higher than the fair value of the Company's ordinary shares. The Company incurred issuance cost of US$2,646 for the issuance of such preferred shares, which was treated as an adjustment to the initial value of the redeemable preferred shares. The Company has elected to measure the redeemable preferred shares by recognizing changes in the redemption value immediately as they occur and adjust the carrying amount to equal the redemption value at the end of each reporting period. As a result, such issuance cost is immediately recognized as a change in redemption value and charged against retained earnings or, in the absence of retained earnings, by charges against additional paid-in capital. 15 DERIVATIVE FINANCIAL INSTRMENTS As of December 31, 2018 and 2019, the Company had outstanding interest rate swap contracts with notional amounts of US$82,200 and US$118,500, respectively.

F-48 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) Long-term borrowings—fair value is based on the amount of future cash flows associated with each debt instrument discounted at the Company’s current borrowing rate for similar debt instruments of comparable terms. The carrying values of the long-term borrowings approximate their fair values as all the long-term debt carry variable interest rates which approximate rates currently offered by the Company’s bankers for similar debt instruments of comparable maturities. Convertible bonds payable—the estimated fair value was RMB2,448,646 as of December 31, 2019. The fair value was measured based on the price in the open market. 17 ORDINARY SHARES In October 2017, the Company issued 64,257,028 Class A ordinary shares to CyrusOne Inc., a third-party investor, at the price of $1.55625 per share.

Settlement of liability-classified restricted shares award In May, August and November 2017, the Company issued a total of 502,000 fully vested restricted shares to its directors to settle a portion of their remuneration for services provided by the directors, which had been recorded in general and administrative expenses. The number of restricted shares issued was determined by the fair value of the restricted shares on the date of settlement and the share-settled portion of the liability of RMB4,462. In March, May, August and November 2018, the Company issued a total of 260,560 fully vested restricted shares to its directors to settle a portion of their remuneration for services provided by the directors, which had been recorded in general and administrative expenses. The number of restricted shares issued was determined by the fair value of the restricted shares on the date of settlement and the share-settled portion of the liability of RMB6,357. In March, May, August and November 2019, the Company issued a total of 237,312 fully vested restricted shares to its directors to settle a portion of their remuneration for services provided by the directors, which had been recorded in general and administrative expenses. The number of restricted shares issued was determined by the fair value of the restricted shares on the date of settlement and the share-settled portion of the liability of RMB7,984. Upon issuance of the shares to settle the obligation, equity is increased by the amount of the liability settled in shares and no additional share-based compensation expense was recorded. Restricted shares to directors, officers and employees In December 2017, July 2018 and August 2019, the Company granted non-vested restricted shares of 13,475,060, 12,941,952 and 14,314,160, respectively, to employees, officers and directors. The restricted share awards contained service and market conditions, or service and performance conditions, which are tied to the financial performance of the Company. For restricted shares granted, the value of the restricted shares was determined by the fair value of the restricted shares on the grant date, on which all criteria for establishing the grant dates were satisfied. The value of restricted shares subject to service conditions and market conditions attached is recognized as the compensation expense using the graded-vesting method. The value of restricted shares with performance conditions attached is recognized as compensation expense using the graded-vesting method only when the achievement of performance conditions becomes probable. For restricted shares with market conditions, the probability to achieve market conditions is reflected in the grant date fair value.

This balance is net of a valuation allowance of RMB205,976 recorded by the Company. The deferred tax assets for net operating loss carry forwards and related valuation allowance were RMB235,057 and RMB181,985, respectively. This valuation allowance was related to the deferred tax assets of certain subsidiaries of the Company. These entities were in a cumulative loss position with net operating loss carry forwards which are subject to expiration. Management evaluated the realizability of the deferred tax assets associated with the Company's net operating loss carry forwards to determine whether there was more than a 50% likelihood that these deferred tax assets would be realized, based on the Company's expectations of future taxable income and timing of net operating losses carry forwards expirations. The ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible or utilized. Management considers the scheduled reversal of deferred income tax liabilities, projected future taxable income and tax planning strategies in making this assessment. F-55 GDS HOLDINGS LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of RMB, except share data and per share data, or otherwise noted) The net operating losses carry forwards of the Company’s PRC subsidiaries amounted to RMB978,738 as of December 31, 2019, of which RMB52,656, RMB70,408, RMB146,464, RMB292,983 and RMB416,227 will expire if unused by December 31, 2020, 2021, 2022, 2023 and 2024, respectively. Uncertainties exist with respect to how the current income tax law in the PRC applies to the Company’s overall operations, and more specifically, with regard to tax residency status. The 2008 Enterprise Income Tax Law (the " EIT Law”) includes a provision specifying that legal entities organized outside the PRC are considered residents for Chinese income tax purposes if the place of effective management or control is within the PRC. The implementation rules to the EIT Law provide that non-resident legal entities are considered PRC residents if substantial and overall management and control over the manufacturing and business operations, personnel, accounting, properties, etc., occurs within the PRC. Despite the present uncertainties resulting from the limited PRC tax guidance on the issue, the Company does not believe that the legal entities organized outside the PRC should be treated as residents for EIT Law purposes. If the PRC tax authorities subsequently determine that the Company and its subsidiaries registered outside the PRC are deemed resident enterprises, the Company and its subsidiaries registered outside the PRC will be subject to the PRC income tax at a rate of 25%. If the Company were to be non-resident for PRC tax purposes, dividends paid to it from profits earned by the PRC subsidiaries after January 1, 2008 would be subject to a withholding tax. The EIT Law and its relevant regulations impose a withholding tax at 10%, unless reduced by a tax treaty or agreement, for dividends distributed by a PRC-resident enterprise to its non-PRC-resident corporate investor for earnings generated beginning on January 1, 2008. Undistributed earnings generated prior to January 1, 2008 are exempt from such withholding tax. The Company has not recognized any deferred tax liability for the undistributed earnings of the PRC-resident enterprise as of December 31, 2018 and 2019, as the Company plans to permanently reinvest these earnings in the PRC. Each of the PRC subsidiaries does not have a plan to pay dividends in the foreseeable future and intends to retain any future earnings for use in the operation and expansion of its business in the PRC. 21 DISTRIBUTION OF PROFIT Pursuant to the laws and regulations of the PRC, the Company’s PRC entities are required to allocate at least 10% of their after tax profits, after making good of accumulated losses as reported in their PRC statutory financial statements, to the general reserve fund and have the right to discontinue allocations to the general reserve fund if the balance of such reserve has reached 50% of their registered capital. The general reserves are not available for distribution to the shareholders (except in liquidation) and may not be transferred in the form of loans, advances, or cash dividend. These PRC entities are restricted in their ability to transfer the registered capital and general reserve fund to GDS Holdings in the form of dividends, loans or advances. The restricted portion amounted to RMB4,768,715 and RMB7,367,536 as of December 31, 2018 and 2019, respectively, including non-distributable general reserve fund of RMB579 and RMB15,712 as of December 31, 2018 and 2019, respectively. The parent company financial information of GDS Holdings is disclosed in note 27.

No consideration was received by the Company for this issuance of ordinary shares. These ordinary shares are legally issued and outstanding but are treated as escrowed shares for accounting purposes and, therefore, have been excluded from the computation of loss per ordinary share. Any ordinary shares not used in the settlement of stock option and restricted share awards will be returned to the Company. The following securities were excluded from the computation of diluted loss per share as inclusion would have been anti-dilutive.
