Fluorescent light bulbs, low- flow shower heads, and vehicle mileage standards were designed to make the U.S. more secure. We were driven not by the risk of climate change, but instead by the risk of supply shortages and price volatility. The progress the clean energy business has made since the 1970s is built on the fundamental need to have secure energy supplies at reliable prices. The invasion of Ukraine by Russia is a reminder to Europe, and to a lesser extent the U.S., of the importance of controlling, as much as possible, a country’s energy supplies, lest one become beholden to hostile regimes. Europe’s reliance on Russian natural gas for heating buildings is a lesson not learned from the shocks of the 1970s. Heating buildings could be easily and more economically accomplished by the electrification of homes and buildings using heat pumps and distributed solar. Shutting down nuclear plants might make sense once Europe’s electric power needs have been secured with renewables and storage but is premature if still reliant on Russian natural gas. Energy security is national security. In some respects, energy markets have been too stable since the 1970s, causing us to forget this fundamental lesson from history. In the very short term, like in times of war, worrying about climate change is a luxury. But after the conflict ends, for better or for worse, the need to accelerate investments in climate solutions is even more obvious and urgent. A country can and should improve its national security and climate security by scaling up investments in climate solutions. Countries can and should improve their national security and climate security by scaling up investments in climate solutions. Dear Stakeholders: This annual letter was originally about how the integrity and rigor of our ESG approach produces tangible shareholder value due to high employee retention, which is crucial for solving client problems, building institutional memory, and achieving operating efficiencies. These are important advantages for our business. But the tragic events unfolding in Ukraine cause me to go back to the beginning of my journey in the energy industry in the 1970s and remember the origins of energy efficiency, solar, and wind in the U.S. The twin Arab oil embargoes of 1973 and 1978 shocked the world, causing us all to realize how reliance on fossil fuels from unstable countries creates significant risk for economies and people. The price shocks launched the energy efficiency and renewable energy industries to reduce reliance on oil in the electric power and Investment in “Black Rock,” a 115 MW wind farm located in Grant and Mineral Counties, West Virginia, USA. Conclusion Our hearts are with the people of Ukraine during this horrific war. Meanwhile, we will continue to expand our efforts in climate solutions investing, making the U.S. stronger while reducing our risks to climate change. Respectfully, Jeffrey W. Eckel Chairman and CEO March 2022 2021 Review and Outlook for 2022 We invested more than $1.7 billion in climate solutions in 2021, resulting in a 24% increase in our Portfolio and a corresponding 52% increase in Distributable Net Investment Income. As a result, HASI continued its strong financial performance in 2021, increasing Distributable Earnings per Share by 21%. The market opportunity for climate solutions has never been larger, and we continue to see an attractive and diversified set of expanding markets in which to invest. Despite the well- noted supply chain and inflation issues impacting most industries, strong demand for climate solutions will continue for decades. We invested heavily in talent and technology in 2021, increasing our capacity to grow our business and serve our clients. As a result, we maintained our Portfolio yield at 7.5% and expect it to remain attractive if interest rates move higher. We also reduced our average cost of funds, primarily driven by a large fixed-rate borrowing issued at a ver y l o w c o u p o n a n d b y o b t a i n i n g a revolving line-of-credit and a first-of-its- kind CarbonCount ®-based Commercial Paper program. We look for ward to strong growth in 2022 as our dual revenue business model continues to perform in the growing climate solutions investment market. HASI’s breadth of end markets generates diverse investment opportunities, increasing the stability of our business. As an example, our Portfolio of almost 300 discrete investments across all our end markets provides robust recurring revenue streams. Finally, the flexibility we enjoy in funding our liabilities, including our securitization platform, allows us to grow in any interest rate environment. Considering all of this, we increased and extended our Distributable Earnings guidance to 10% - 13% through 2024. Given the strong earnings growth, our Board felt it appropriate to also raise our dividend by 7% in the first quarter of 2022. 0 4 | | 0 5 HANNON ARMSTRONG | 2021 ANNUAL REPORTHANNON ARMSTRONG | 2021 ANNUAL REPORT R E C E N T H I G H L I G H T S G R O W T H H I G H L I G H T S Key Performance Indicators GAAP and Distributable EPS1 NII1 and Gain on Sale and Fees EPS NII Portfolio Yield1 Portfolio2 Managed Assets1 Distributable ROE3 Pipeline Transactions Closed GAAP Distributable1 GAAP-based FY21 $1.51 $1.88 $11m Distributable1 $134m 7.5% $3.6b $8.8b 11.2% >$4b $1.7b Growth (YOY) +21% +52% +24% FY20 $1.10 $1.55 $29m $88m 7.6% $2.9b $7.2b 10.7% >$3b $1.9b FY21 0.5 4 FY20 1.0 Incremental Annual Reduction in Carbon Emissions ~817k MT ~2.0m MT TM 5 FY20 303 FY21 140 Incremental Annual Water Savings ~228 MG ~576 MG Increase and Extension of Guidance Distributable EPS Expected Compounded Annual Growth Guidance Distributable EPS (2021 – 2024)1,6 10% – 13% (CAGR) e c n a u i d G $2.53 $2.40 $2.27 +21% YOY $1.88 $1.51 $1.55 +52% YOY $134 $1.10 $88 +23% YOY $80 $65 2020 2021 2020 2021 2020 2021 2020 2021 GAAP Distributable Distributable NII Gain on Sale and Fees Managed Assets1 Portfolio Yield1 and Distributable ROE2 17 % CAGR $4.7b $5.3b $8.8b $6.2b $7.2b 10.2% 11.1% 10.5% 10.7% 11.2% 6.1% 6.8% 7.6% 7.6% 7.5% Dividends Per Share Guidance: 5% - 8% $1.55 2020 $1.88 2021 2022 2023 2024 $2.0 2017 $2.0 2018 $2.1 2019 $2.9 2020 $3.6 2021 Off Balance Sheet Balance Sheet Portfolio Off Balance Sheet Balance Sheet Portfolio 2017 2018 2019 2020 2021 Portfolio Yield Distributable ROE 1) See Appendix for an explanation of Distributable Earnings, Distributable Net Investment Income, Portfolio Yield and Managed Assets, including reconciliations to the relevant GAAP measures, where applicable. 2) GAAP-based. 3) Distributable ROE is calculated using Distributable Earnings for the period and the average of the quarterly ending equity balances for the period. 4) CarbonCount is a scoring tool that evaluates investments in U.S.-based energy efficiency and renewable energy projects to estimate the expected CO2 emission reduction per $1,000 of investment. 5) WaterCount is a scoring tool that evaluates investments in U.S.-based projects to estimate the expected water consumption reduction per $1,000 of investment. 6) Relative to the 2020 baseline. 1) See Appendix for an explanation of Distributable Earnings, Distributable Net Investment Income, Managed Assets, and Portfolio Yield, including reconciliations to the relevant GAAP measures, where applicable. 2) Distributable ROE is calculated using Distributable Earnings for the period and the average of the quarterly ending equity balances for the period. 0 6 | | 0 7 HANNON ARMSTRONG | 2021 ANNUAL REPORTHANNON ARMSTRONG | 2021 ANNUAL REPORT I N V E S T M E N T S P O T L I G H T S GRID-CONNECTED BEHIND-THE-METER BEHIND-THE-METER >$660m CARBONCOUNT: 1.06 Preferred equity investment with Clearway Energy in a 2 GW portfolio of contracted, grid- connected wind, solar, and s o l a r - p l u s - s t o r a g e p r o j e c t s , located across four states, with predominantly investment-grade counterparties and a weighted- average contract life of 14 years.

CarbonCount is a scoring tool that evaluates investments in U.S.-based, energy efficiency and renewable energy projects to determine estimated CO2 emissions avoided annually per $1,000 of investment. Estimated carbon savings are calculated using the estimated kilowatt hours (“kWh”), gallons of fuel oil, million British thermal units (“MMBtus”) of natural gas and gallons of water saved as appropriate, for each project. The energy savings are converted into an estimate of metric tons of CO2 equivalent emissions based upon the project’s location and the corresponding emissions factor data from the U.S. Government and International Energy Administration. Portfolios of projects are represented on an aggregate basis. Estimated water savings are calculated as the sum of the direct annual estimated water savings from energy efficiency measures such as low - flow water fixtures and the annual indirect water savings associated with the annual kWh generated and saved by our investments. The annual kWh of electricity generated and saved by our investments are multiplied by the amount of water withdrawn and not returned to local water systems based upon the project’s location and the existing grid electricity generating units in that region. Indirect water savings is estimated using data prepared by the U.S. Government’s Energy Information Administration and the Union of Concerned Scientists. L E A D E R S H I P T E A M JEFFREY W.

You should carefully consider the risks summarized in Item 1A, “Risk Factors” included in this report. These risks include, but are not limited to, the following: Risks Related to Our Business and Our Industry z Our business depends in part on U.S. federal, state and local government policies and a decline in the level of government support could harm our business. z A change in the fiscal health, level of appropriations or budgets of U.S. federal, state and local governments could reduce demand for the projects in which we invest and the capital we provide. z If the cost of energy generated by traditional sources of energy declines or continues to remain low, demand for the projects in which we invest may decline. z We operate in a competitive market and future competition may impact the terms of the investments we make. Risks Related to Our Assets and Projects in Which We Invest z The lack of liquidity of our assets may adversely affect our business, including our ability to value our assets. z We rely on our project sponsors for financial reporting related to our project companies, and our financial statements may be materially affected if the financial reporting related to our project companies proves to be incorrect. z Our investments are subject to delinquency, foreclosure and loss, any or all of which could result in losses to us. z Our mezzanine or subordinated loans are riskier, less protected against loss than, and generally less liquid than, other forms of debt with more senior preference. z Our equity investments, many of which are illiquid with no readily available market, involve a substantial degree of risk. z We generally do not control the projects in which we invest, which may result in the project owner making certain business decisions or taking risks with which we disagree. z Portions of the electricity our assets generate is sold on the open market at spot-market prices. A prolonged environment of low prices for natural gas, or other conventional fuel sources may have a material adverse effect on our long-term business prospects, financial condition and results of operations. z Some of the projects in which we invest may require substantial operating or capital expenditures in the future. z We invest in projects which rely on third parties to manufacture quality products or provide reliable services in a timely manner and the failure of these third parties could cause project performance to be adversely affected. z Our insurance and contractual protections may not always cover lost revenue, increased expenses or liquidated damages payments. z Energy efficiency, renewable energy and other sustainable infrastructure projects are subject to performance risks, including risks due to extreme weather events, that could impact the repayment of and the return on our assets. Risks Related to Our Company z We may change our operational policies (including our investment guidelines and strategies) with the approval of our board of directors (“Board”) but without stockholder consent at any time, which may adversely affect the market value of our common stock and our ability to make distributions to our stockholders. z An increase in our borrowing costs relative to the interest we receive on our assets may adversely affect our profitability and our cash available for distribution to our stockholders. Our borrowings may have a shorter duration than our assets. z While we have an established Board-approved leverage limit, our Board may change our financial leverage guidelines without stockholder consent. Risks Related to Our Common Stock z We cannot assure you of our ability to make distributions in the future. Although we currently do not intend to do so, if our portfolio of assets does not generate sufficient income and cash flow, we could be required to sell assets, borrow funds or make a portion of our distributions in the form of a taxable stock distribution or distribution of debt securities in order to maintain our qualification as a REIT. Risks Related to Our Organization and Structure z Our qualification as a REIT depends on interpretations of highly technical and complex legal provisions, and our failure to qualify or remain qualified as a REIT would subject us to taxes that would negatively impact the results of our operations and reduce the amount of cash available for distribution to our stockholders. Risks Related to Our Taxation as a REIT z Complying with REIT requirements may force us to liquidate assets or forego otherwise attractive investments. Risks Related to COVID-19 z The current outbreak and spread of COVID-19 continues to disrupt the U.S. and global economies and financial markets and create widespread business continuity and viability issues. 4 | HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I PART I In this Form 10-K, unless specifically stated otherwise or the context otherwise indicates, references to “we,” “our,” “us,” “HASI,” and “our company” refer to Hannon Armstrong Sustainable Infrastructure Capital, Inc., a Maryland corporation and any of our subsidiaries. Hannon Armstrong Sustainable Infrastructure, L.P., a Delaware limited partnership, is a subsidiary of which we are the sole general partner and to which we refer in this Form 10-K as our “Operating Partnership.” Our business is focused on reducing the impact of greenhouse gases that have been scientifically linked to climate change. We refer to these gases, which are often for consistency expressed as carbon dioxide equivalents, as carbon emissions. ITEM 1.

We have long-standing relationships with the leading energy service companies (“ESCOs”), manufacturers, project developers, utilities, owners and operators, which provide recurring, programmatic investment and fee-generating opportunities. Additionally, we have relationships with leading commercial and investment banks and institutional investors from which we are referred additional investment and fee-generating opportunities. We completed approximately $1.7 billion of transactions during 2021, compared to approximately $1.9 billion during 2020. As of December 31, 2021, we held approximately $3.6 billion of transactions on our balance sheet, which we refer to as our “Portfolio.” For those transactions that we choose not to hold on our balance sheet, we transfer all or a portion of the economics of the transaction, typically using securitization trusts, to institutional investors in exchange for cash and, in certain cases, residual interests in the trusts and ongoing fees. As of December 31, 2021, we managed approximately $5.2 billion in these trusts or vehicles that are not consolidated on our balance sheet. When we combine these assets with our Portfolio, as of December 31, 2021, we manage approximately $8.8 billion of assets, which we refer to as our “Managed Assets.” Our investments take many forms, including equity, joint ventures, land ownership, loans, and other financing transactions. We also generate ongoing fees via off-balance sheet securitization transactions, advisory services, and asset management. We use borrowings as part of our strategy to fund our investments in climate solutions and have available to us a broad range of financing sources including short-term commercial paper issuances, revolving credit facilities, non-recourse or recourse debt, equity, and off-balance sheet securitization structures. We calculate the estimated carbon emission savings using CarbonCount®, a proprietary tool which measures the efficiency with which our investments reduce carbon emissions, and generally provide the associated CarbonCount metrics for our debt issuances. In addition, certain of our debt issuances meet the environmental eligibility criteria for green bonds as defined by the International Capital Markets Association’s Green Bond Principles, which we believe makes our debt more attractive for many investors compared to such offerings that do not qualify under these principles. A further description of our financing activities can be found herein. We have a large and active pipeline of potential new opportunities that are in various stages of our underwriting process. We refer to potential opportunities as being part of our pipeline if we have determined that the project fits within our climate solutions investment strategy and exhibits the appropriate risk and reward characteristics through an initial credit analysis, including a quantitative and qualitative assessment of the opportunity, as well as research on the relevant market and sponsor. Our pipeline of transactions that could potentially close in the next 12 months consists of opportunities in which we | 5 HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1. BUSINESS will be the lead originator as well as opportunities in which we may participate with other institutional investors. As of December 31, 2021, our pipeline consisted of more than $4.0 billion in new equity, debt and real estate opportunities. There can, however, be no assurance with regard to any specific terms of such pipeline transactions or that any or all of the transactions in our pipeline will be completed. We are committed to leadership in transparent disclosure on environmental, social, and governance (“ESG”) matters. Beginning in 2013, we became one of the first capital providers to evaluate the carbon efficiency of our Portfolio by utilizing CarbonCount. In 2017, we believe we were the first U.S-based public company to commit to the Climate Disclosure Standards Board led initiative on implementing the recommendations of the Financial Stability Board’s Task Force for Climate-related Financial Disclosures (“TCFD”) and provide the recommended disclosures in our Form 10-K. In 2020, we joined the Partnership for Carbon Accounting Financials (“PCAF”), a global financial industry-led partnership to implement a consistent and transparent disclosure framework to report carbon emissions and avoided emissions resulting from financed assets. We anticipate that our reporting in accordance with PCAF will be implemented by 2023. For further information on our ESG disclosures, see the discussion in the sections titled “Investment Strategy” and “Environmental and Social Responsibility and Corporate Governance” herein. We are committed to providing transparent disclosures on our human capital management, which can be found herein in the section titled “Human Capital Strategy.” In 2021, we founded the Hannon Armstrong Foundation, which provides cash and in-kind support to programs that align with our philanthropic priorities of ensuring equal access to climate solutions, empowering and creating opportunity for marginalized individuals and communities, and creating a local impact. We elected to be taxed as a REIT for U.S. federal income tax purposes commencing with our taxable year ended December 31, 2013, and operate our business in a manner that permits us to maintain our exemption from registration as an investment company under the 1940 Act. Investment strategy With scientific consensus that global-warming trends are linked to human activities and result in various extreme weather events, we believe our firm is well-positioned to generate attractive risk-adjusted returns by investing in, and managing a portfolio of, assets that address climate-changing greenhouse gas emissions. Further, with increasing weather-related disasters, we see similar investment opportunities in infrastructure assets that mitigate the impact of, and increase the resiliency to, these weather events and other adverse impacts of climate change. Our vision is that every investment improves our climate future and thus the carbon impact of an investment is at the core of our business model. We believe that climate positive investments will produce attractive risk adjusted returns and we require investments to be neutral to negative on incremental carbon emissions or have some other tangible environmental benefit such as reducing water consumption or increasing resilience to climate change influenced weather events. Our climate-positive investment thesis is based on the following theories: z more efficient technologies are more productive and thus should lead to higher economic returns; z lower portfolio risk is inherent in a portfolio of smaller investments, generated by trends of increasing decentralization and digitalization of energy assets; z investing in assets aligned with scientific consensus and broadly held societal values will reduce potential regulatory and social costs through more internalization of externalities; and z assets that reduce carbon emissions represent an embedded option that may increase in value if regulatory authorities were to set a price on carbon emissions. We believe combining this investment thesis with our multi-decade experience in investing in our markets through multiple interest rate and business cycles, intermittent governmental support for reducing carbon emissions and several cycles of business expansions in renewable and other sustainable infrastructure markets, allows us to earn attractive risk-adjusted returns on the assets in which we invest. We also believe there is a very large potential market opportunity 6 | as the legacy technologies for generating and using energy and the systems that produce carbon emissions are retired and replaced by low-to-no carbon emission systems. Mitigation and resiliency investments continue to grow to address severe weather events and other climate change impacts. Our investments in climate solutions are focused on three markets: z Behind-the-Meter (“BTM”): distributed building or facility projects, which reduce energy usage or cost through the use of solar generation and energy storage or energy efficiency improvements including heating, ventilation and air conditioning systems (“HVAC”), lighting, energy controls, roofs, windows, building shells, and/or combined heat and power systems; z Grid-Connected (“GC”): projects that deploy cleaner energy sources, such as solar and wind to generate power where the off-taker or counterparty is part of the wholesale electric power grid; and z Sustainable Infrastructure (“SI”): upgraded transmission and distribution systems, water and storm water infrastructure, and other projects that improve water or energy efficiency, increase resiliency, positively impact the environment or more efficiently use natural resources. Of our pipeline, 48% is related to BTM assets and 37% is related to GC assets, with the remainder related to SI. We prefer investments in which the assets use proven technology and have a long-term, creditworthy off-taker or counterparties. For BTM assets, the off-taker or counterparty may be the building owner or occupant, and our investment may be secured by the installed improvements or other real estate rights. For GC assets, the off-takers or counterparties may be utility or electric users who have entered into contractual commitments, such as power purchase agreements (“PPAs”), to purchase power produced by a renewable energy project at a specified price with potential price escalators for a portion of the project’s estimated life. We make our investments utilizing a variety of structures, including: z equity investments in either preferred or common structures in unconsolidated entities which own renewable energy or energy efficiency projects; HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1. BUSINESS z commercial and government receivables or securities, such as loans for renewable energy and energy efficiency projects; and z real estate, such as land or other assets leased for use by GC projects typically under long term leases. Our equity investments in renewable energy and energy efficiency projects are operated by various renewable energy companies or by joint ventures in which we participate. These transactions allow us to participate in the cash flows associated with these projects, typically on a priority basis. Our energy efficiency debt investments are usually assigned the payment stream from the project savings and other contractual rights, often using our pre-existing master purchase agreements with the ESCOs. Our debt investments in various renewable energy or other sustainable infrastructure project companies or portfolios of project companies are in many cases secured by the installed improvements, or other real estate rights. We also own, directly or through equity investments, land that is leased under long-term agreements to renewable energy projects where our investment returns are typically senior to most project costs, debt, and equity. We often make investments where we hold a preferred or mezzanine position in a project company where we are subordinated to project debt and/or preferred forms of equity. Investing greater than 10% of our assets in any individual project company requires the approval of a majority of our independent directors. We may adjust the mix and duration of our assets over time in order to allow us to manage various aspects of our Portfolio, including expected risk-adjusted returns, macroeconomic conditions, liquidity, availability of adequate financing for our assets, and the maintenance of our REIT qualification and our exemption from registration as an investment company under the 1940 Act. Financing strategy We believe we have available a broad range of financing sources as part of our strategy to fund our investments in climate solutions. We may finance our investments through the use of non-recourse debt, recourse debt or equity and may also decide to finance such transactions through the use of off-balance sheet securitization structures. When issuing debt, we generally provide the estimated carbon emission savings using CarbonCount. In addition, certain of our debt issuances meet the environmental eligibility criteria for green bonds as defined by the International Capital Markets Association’s Green Bond Principles, which we believe makes our debt more attractive for many investors compared to such offerings that do not qualify under these principles. We plan to raise additional equity capital and continue to use fixed and floating rate borrowings, which may be in the form of short-term commercial paper issuances, revolving credit facilities, term loans, repurchase agreements, and public and private debt issuances as a means of financing our business. We also expect to use both on-balance sheet and off-balance sheet securitizations. We may also consider the use of special purpose entities or funds in which outside investors participate to allow us to expand the investments that we make or to manage our Portfolio diversification. The decision on how we finance specific assets or groups of assets is largely driven by market conditions including the overall interest rate environment, prevailing credit spreads and the terms of available financing. During periods of market disruption, certain sources of financing may be more readily accessible than others which may impact our financing decisions. Over time, as market conditions change, we may use other forms of financial leverage in addition As of December 31, 2021, our Portfolio consisted of over 285 investments, with approximately 53% of our Portfolio invested in BTM assets and approximately 47% invested in GC assets, which include our land holdings. The mix of our Portfolio is expected to vary over time, as we seek to manage the diversity of our Portfolio by, among other factors, project type, project operator, type of investment, type of technology, transaction size, geography, obligor, and maturity. As part of our investment process, we calculate the ratio of the estimated first year of metric tons of carbon emissions avoided by our investments divided by the capital invested to quantify the carbon impact of our investments. In this calculation, which we refer to as CarbonCount, we use emissions factor data, expressed on a CO2 equivalent basis, from the U.S. Government or the International Energy Administration to an estimate of a project’s energy production or savings to compute an estimate of metric tons of carbon emissions avoided. We estimate that our investments originated in 2021 will reduce annual carbon emissions by approximately 0.8 million metric tons, equating to a CarbonCount of 0.50. In addition to carbon, we also consider other environmental attributes, such as water use reduction, stormwater remediation benefits and stream restoration benefits. We believe that our long history of climate solutions investing, the experience, expertise and relationships of our management team, the anticipated credit strength of the obligors or investees involved in our investments and the size and growth potential of our market, position us well to capitalize on our strategy. Refer to Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations, for additional discussion on the performance of our Portfolio. to these financing arrangements. Although we are not restricted by any regulatory requirements as to the type or amount of financial leverage we may use, we do seek to, but are not required to, operate within certain metrics, including maintaining a financial leverage ratio, defined as the ratio of debt to equity, at or below 2.5 to 1. In addition, our board of directors (our “Board”) has established a current target range for our percentage of fixed rate debt to total debt of between 75% and 100%. See additional discussion in “Item 7. Management’s Discussion and Analysis of Financial Conditions and Results of Operations—Liquidity and Capital Resources” regarding our ongoing evaluation of our leverage limits and fixed-rate debt targets. For those transactions that we choose not to hold on our balance sheet, we transfer all or a portion of the economics of the transaction, typically using securitization trusts, to institutional investors in exchange for cash and/or residual interests in the assets and in some cases, ongoing fees. The availability of securitization counterparties has remained high throughout various market cycles due to investor demand for high credit quality, long-term climate-positive investments. We may arrange such securitizations of loans or other assets prior to originating the transaction and thus avoid exposure to credit spread, interest rate and funding risks. We also typically manage and service these assets in exchange for fees. We may also use other funds or structures where institutional investors purchase all or a portion of the economics of the transaction and where we may receive upfront or ongoing fees for managing the assets. We periodically provide other services, including arranging financings that are held on the balance sheets of other investors and advising various companies with respect to structuring investments. | 7 HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1. BUSINESS Refer to Item 7. Management’s Discussion and Analysis of Financial Conditions and Results of Operations—Liquidity and Capital Resources, for additional discussion on our financings and our ratios and Item 8. Financial Statements and Supplementary Data, Notes 5, 7 and 8 to our financial statements for further information on the types and amounts of our financing activities. Human capital strategy An emphasis on a durable social fabric, including diverse, engaged, and fairly compensated staff, is an important factor in our financial success. Our culture is focused on hiring and retaining highly talented employees with diverse backgrounds and empowering them to create value for our stockholders, and our success is dependent on employee understanding of and investment in their role in that value creation. Our employees are responsible for upholding our purpose, values, strategy, and talent leadership expectations. It is important to us that our employees are engaged in our mission of sustainability because we believe engagement improves their performance, as well as our employee recruitment and retention. Our chief executive officer periodically leads employee meetings intended to reinforce the importance of sustainability and regularly meets with small groups of employees to receive their feedback on our business. We also meet no less than quarterly as a Company to provide information to employees on our mission, strategic planning and financial results. We continuously evaluate our employees’ level of engagement through in-person meetings or remote one-on-one check- in calls that include asking open-ended questions and through formal surveys or similar tools administered on a periodic basis. We adhere to a blended learning approach with the understanding that our people learn from experiences (on the job and in life), from other people (mentors or supportive managers), and from formal learning and training programs. We acknowledge that learning is highly individualized and needs to be offered in a way that is most conducive to a specific learner’s needs. We run a periodic education series that includes internal and external speakers presenting topics of interest that are relevant to our employees. We provide multiple learning solutions that cover a wide range of areas such as diversity, equity, and inclusion training, leadership skills, financial knowledge, technology training, and presentation skills. We also support the pursuit of advanced certifications and degrees in areas including business, science and engineering, and liberal and fine arts and employ formal and informal coaching arrangements. We care about our employees’ employment experience and recognize them as individuals who are motivated in different ways. Managers hold performance conversations with their employees on a periodic basis (targeting a minimum of twice a year) to ensure they receive the performance feedback they deserve, and to allow managers to obtain insight into how to support the development of their staff, and to ensure that performance expectations are clear and aligned with the overarching objectives of the Company. We also provide continuous dialogue in between these formal touchpoints. We believe we provide attractive benefits that promote the health of our employees and their families and design compelling job opportunities, aligned with our mission, in an energizing work environment. We also encourage our employees to continue to develop in their careers, including by obtaining advanced degrees or professional certifications. We compensate our employees according to our fair remuneration policies and believe in paying for performance. Therefore, employees generally receive a portion of their compensation in the form of annual bonuses as well as equity grants which are both tied in part to the Company’s financial performance. We encourage our employees to contribute their time to support various community and charitable activities and sponsor several local community organizations with a primary focus on organizations addressing issues around environmental and social justice. In addition to competitive base salaries, cash bonuses, and equity participation for most employees, we are committed to continuously evaluating and ensuring the competitiveness of our benefits offerings so that we meet the various needs of our employees and their families. Despite a healthcare environment that is facing rising costs, we continue to pay substantially all of the cost of our employees’ healthcare insurance. Further, in addition to what we believe to be market total rewards benefits, we provide additional benefits, such as on-site influenza and COVID-19 vaccination clinics and a tuition reimbursement program. We take a values-driven, broad view of diversity, equity, and inclusion. We believe that fostering an internal climate that is supportive and allows people of all backgrounds to flourish lends itself to the highest levels of company performance and facilitates the attraction and retention of best-in-class talent. We also believe it is inherently the right way to conduct business. We support an innovative, creative culture where people can bring their best and most authentic selves to work. Employees who hold divergent opinions are encouraged to voice their views. We track and report internally on key talent metrics including workforce demographics, critical role pipeline data, diversity data, and engagement and inclusion indices. Decisions regarding staffing, selection, and promotions are made on the basis of individual qualifications related to the requirements of the position. We are committed to identifying and developing the talents of our next generation of leaders. We endeavor to select qualified individuals from a diverse pool of candidates derived from broad outreach efforts when we are recruiting. We are committed to the sourcing and/or promotion of highly-qualified women, people of color and other under-represented groups for management and Board positions. To better support our female and underrepresented employees in their onboarding, training, development and progression within the Company, we have established a mentorship program where certain members of our Board mentor female employees who are developing managers. Our policy is “equal pay for equal work” in compliance with applicable state law. Compensation for our employees is based upon experience, seniority, educational attainment, and individual contribution and company performance against goals. As of December 31, 2021, we employed 99 people. We intend to hire additional business professionals as needed to assist in the implementation of our business strategy. Refer to “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Results of Operations – Human Capital Metrics” for discussion of metrics related to our Human Capital Strategy. 8 | HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1. BUSINESS Environmental and social responsibility and corporate governance We own and invest in a diversified portfolio of climate solutions projects focused on reducing or mitigating the impacts of climate change. Under the direction of our chief executive officer and the Board, we are focused on achieving a high level of environmental and social responsibility and strong corporate governance. The Nominating, Governance and Corporate Responsibility Committee of our Board is responsible for our ESG oversight, including related policies and communications. Additionally, we have a committee of employees from across our organization that is focused on implementing ESG strategies and policies and reports directly to our chief executive officer. Annually we publish a report that illustrates our progress on these matters. We are determined to incorporate climate justice ideals and actions across our entire business, including in our process for underwriting investments, our engagement with business partners, our human capital strategy, philanthropy, and policy advocacy efforts. In 2021, we established the Hannon Armstrong Foundation, that provides cash and in-kind support to programs which provide climate solutions investments and career opportunities for those from historically underrepresented communities, as well as organizations across our local region that seek to strengthen the social fabric and promote economic and climate resiliency. Environmental Responsibility. Our business and business strategy are focused on addressing climate change, in part through the reduction of carbon emissions that have been scientifically linked to climate change. As described under “Investment Strategy”, we quantify the carbon impact of each of our investments. In addition, we operate our business in a manner intended to reduce our own environmental impact, including by purchasing carbon-free renewable energy for our office, encouraging recycling and composting, and offering clean transportation employee incentives for electric and hybrid vehicles. We have also adopted policies focused on minimizing the environmental impact of our operations. Through our membership in the Net Zero Asset Managers Initiative, we are pleased to participate in the Glasgow Financial Alliance for Net Zero, which brings the financial sector together to accelerate a shared commitment to decarbonizing the global economy. In 2021, we established targets for our transition to net-zero carbon emissions by 2050 using the foundational framework developed by the Science Based Targets Initiative. We are a signatory to the United Nations Global Compact, an initiative focused on responsible business practices related to human rights, labor, the environment and anti-corruption. We participate in a number of initiatives and coalitions that share our commitment to climate action, corporate sustainability, climate-risk disclosure and reporting, and the expansion of clean energy including the United Nations-supported Principles for Responsible Investment, the United Nations Global Compact campaign entitled Business Ambition for 1.5°, Climate Action 100+, and the reporting framework established by an international consortium of business and environmental NGOs referred to as the Climate Disclosure Standards Board. Social Responsibility. We recognize that the effects of pollution, environmental degradation, increased climate-fueled extreme weather events, and the economic transition away from fossil fuels fall most heavily on marginalized communities in our society, especially communities of color. We know that the effects of climate change are already disproportionately impacting disadvantaged communities, and these adverse outcomes will be exacerbated if we do not eliminate harmful greenhouse gas emissions. Equally so, we acknowledge the legacy of discriminatory policies in creating and perpetuating this imbalance. We believe in every person’s inherent worth and dignity and that we should all have access to clean water, clean air, healthy food, resilient and reliable shelter and energy, and good paying jobs. We believe these disparities must be addressed while society works to accelerate the transition to a net-zero economy, both here in the United States and across the globe, a concept we refer to as “climate justice”. Corporate Governance. We are focused on achieving best-in-class corporate governance practices to help ensure that our team will operate in a manner consistent with our organizational mission and deliver attractive risk-adjusted returns. Our corporate governance philosophy is based on maintaining a close alignment of our interests with those of our stakeholders. Notable features of our corporate governance structure include the following: z our Corporate Governance Guidelines provide for a majority vote policy for the election of directors pursuant to which any nominee who receives a greater number of votes “withheld” from his or her election than votes “for” such election shall promptly tender his or her resignation to our Board for their consideration to accept or reject such resignation; z our Board is not staggered, with each of our directors subject to re-election annually; z our Board has determined that eight of our nine directors are independent for purposes of the New York Stock Exchange (“NYSE”) corporate governance listing standards and Rule 10A-3 under the Exchange Act; z we have a lead independent director of the Board that convenes and chairs executive sessions of the independent directors to discuss certain matters without management or the chairman present; z four of our directors qualify as an “audit committee financial expert” as defined by the Securities and Exchange Commission (the “SEC”); z three of our directors (including our lead independent director) are women and one of our directors is a person of color constituting 33% and 11% respectively, of our Board in furtherance of our board diversity policy; z a target retirement age of 75 has been established for our directors; z we have an active stockholder outreach program, including providing stockholders the right to vote on an advisory basis on the fairness of the remuneration of executives; z our Board members and named executive officers are required to maintain certain levels of stock ownership in our company ranging between three and six times their base salary or retainer, depending on position; z we have a Clawback Policy that provides for the possible recoupment of performance or incentive-based compensation in the event of an accounting restatement due to material noncompliance by us with any financial reporting requirements under the securities laws (other than due to a change in applicable accounting methods, rules or interpretations); z we have opted out of the control share acquisition statute in the Maryland General Corporations Law (the “MGCL”); | 9 HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1. BUSINESS z stockholders have the ability to amend the Company’s bylaws by the affirmative vote of the holders of a majority of the outstanding shares of common stock of the Company pursuant to a binding proposal submitted by a stockholder; z we have exempted from the business combinations statute in the MGCL transactions that are approved by our Board (including a majority of our directors who are not affiliates or associates of the acquiring person); and z we do not have a stockholder rights plan (i.e., no poison pill). In order to foster the highest standards of ethics and conduct in all business relationships, we have adopted a Code of Business Conduct and Ethics policy (the “Code of Conduct”). This policy covers a wide range of business practices and procedures and applies to our officers, directors, employees, agents, representatives, and consultants. In addition, we have implemented whistleblowing procedures designed to facilitate the report of accounting and auditing matters as well as Code of Conduct matters (the “Whistleblower Policy”) that sets forth procedures by which any Covered Persons (as defined in the Whistleblower Policy) may report, on a confidential basis, concerns Our focus on transparent ESG reporting We believe in transparent reporting relating to ESG matters because we believe such reporting improves the understanding of our financial results. As discussed in the “Investment Strategy” section above, we quantify the environmental impact of every transaction we execute through the application of CarbonCount. Our 2021 CarbonCount and avoided emissions for investments originated in 2021 can be found in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Results of Operations — Environmental Metrics”. We continue to implement the TCFD recommendations, and the recommended disclosures are located in this filing as follows; z Governance - “Environmental and Social Responsibility and Corporate Governance”, z Strategy - “Investment Strategy”, z Risk Management - “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Factors Impacting our Operating Results — Impact of climate of climate change on our future operations (Scenario Analysis)” and “Item 7A. Quantitative and Qualitative Disclosures About Market Risk — Risk Management”, and Competition We compete against a number of parties, including banks, private equity, hedge or infrastructure investment funds, insurance companies, mutual funds, institutional investors, investment banking firms, specialty finance companies, utilities, independent power producers, project developers, pension funds, governmental bodies, private credit platforms, and public entities established to own infrastructure assets and other entities. We compete primarily on the basis of service, price, structure and flexibility as well as the breadth and depth of our expertise. We may at times compete and at other times partner or work as a participant with alternative financing sources. The continued low yields in alternative regarding, among other things, any questionable or unethical accounting, internal accounting controls or auditing matters with our Audit Committee as well as any potential Code of Conduct or ethics violations with our Nominating, Governance and Corporate Responsibility Committee or our Chief Legal Officer. We have adopted a Statement of Corporate Policy Regarding Equity Transactions that governs the process to be followed in the purchase or sale of our securities by any of our directors, officers, employees and consultants and prohibits any such persons from buying or selling our securities on the basis of material nonpublic information, and also prohibits our directors and officers from hedging equity securities of the Company, holding such securities in a margin account or pledging such securities as collateral for a loan. We review all of these policies on a periodic basis with our employees. Our business is managed by our leadership team, subject to the supervision and oversight of our Board. Our directors stay informed about our business by attending meetings of our Board and its committees and through supplemental reports and communications. z Metrics and Targets - “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Results of Operations - Environmental Metrics”. In addition to the above environmental reporting initiatives, in 2020, we joined PCAF, a global financial industry-led partnership to implement a consistent and transparent disclosure framework to report carbon emissions and avoided emissions resulting from financed assets. We expect to implement our reporting in accordance with PCAF by 2023. We also disclose metrics related to our Human Capital Strategy. Refer to “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Results of Operations — Human Capital Metrics”. When issuing debt, including our CarbonCount Green Commercial Paper Notes, we generally provide the estimated carbon emission savings using CarbonCount, and in some instances are able to achieve better borrowing rates by achieving certain CarbonCount scores. Certain of our debt issuances have been evaluated to determine that they meet the environmental eligibility criteria for green bonds as defined by the International Capital Markets Association’s Green Bond Principles. investment opportunities and increasing investor acceptance of the climate solutions market has increased the level of competition we experience. We may also encounter competition in the form of potential customers or our origination partners electing to use their own capital rather than engaging us as an outside capital provider. In addition, we may also face competition based on technological developments that reduce demand for electricity, increase power supplies through existing infrastructure or that otherwise compete with climate solutions projects in which we have invested. We believe that a significant part of our competitive advantage is our management team’s experience and industry expertise. 1 0 | HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1.

Our business and operations are subject to a number of risks and uncertainties, the occurrence of which could adversely affect our business, financial condition, consolidated results of operations and ability to make distributions to stockholders and could cause the value of our capital stock to decline. We may refer to the energy efficiency, renewable energy and the other sustainable infrastructure projects or market collectively as climate solutions projects or the industry. Please also refer to the sections entitled “Forward-Looking Statements” and “Risk Factor Summary”. Risks related to our business and our industry Our business depends in part on U.S. federal, state and local government policies, and a decline in the level of government support could harm our business. The projects in which we invest typically depend in part on various U.S. federal, state or local governmental policies and incentives that support or enhance project economic feasibility. Such policies may include governmental initiatives, laws and regulations designed to reduce energy usage and impact the use of renewable energy or the investment in and the use of climate solutions. U.S. federal policies and incentives include, for example, tax credits (including credits that have been recently reduced and scheduled to be eliminated or phased out in the future), tax deductions, bonus depreciation, federal grants and loan guarantees and energy market regulations. State and local governments policies and incentives include, for example, renewable portfolio standards (“RPS”), commercial property assessed clean energy (“C-PACE”) programs, feed-in tariffs, other tariffs, tax incentives and other cash and non-cash payments. Governmental agencies, commercial entities and developers of climate solutions projects frequently depend on these policies and incentives to help defray the costs associated with, and to finance, various projects. Government regulations also impact the terms of third-party financing provided to support these projects, including through energy savings performance contracts. If any of these government policies, incentives or regulations are adversely amended, delayed, eliminated, reduced, retroactively changed or not extended beyond their current expiration dates, or there is a negative impact from the recent federal law changes or proposals, the operating results of the projects we finance and the demand for, and the returns available from, the investments we make may decline, which could harm our business. U.S. federal, state and local government entities are major participants in, and regulators of, the energy industry, and their actions could be adverse to our project companies or our company. The projects we invest in are subject to substantial regulation by U.S. federal, state and local governmental agencies. For example, many projects require government permits, licenses, concessions, leases 1 2 | HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS or contracts. Government entities, due to the wide-ranging scope of their authority, have significant leverage in setting their contractual and regulatory relationships with third parties. In addition, government permits, licenses, concessions, leases and contracts are generally very complex, which may result in periods of non-compliance, or disputes over interpretation or enforceability. If the projects in which we invest fail to obtain or comply with applicable regulations, permits, or contractual obligations, they could be prevented from being constructed or subjected to monetary penalties or loss of operational rights, which could negatively impact project operating results and the returns on our assets. In addition, government counterparties also may have the discretion to change or increase regulation of project operations, or implement laws or regulations affecting project operations, separate from any contractual rights they may have. These actions could adversely impact the efficient and profitable operation of the projects in which we invest. Contracts with government counterparties that support the projects in which we invest may be more favorable to the government counterparties compared to commercial contracts with private parties. For example, a lease, concession or general service contract may enable the government to modify or terminate the contract without requiring the payment of adequate compensation. Typically, our contracts with government counterparties contain termination provisions including prepayment amounts. In most cases, the prepayment amounts provide us with amounts sufficient to repay the financing we have provided but may be less than amounts that would be payable under “make whole” provisions customarily found in commercial lending arrangements. Government entities may also suspend or debar contractors from doing business with the government or pursue various criminal or civil remedies under various government contract regulations. They may also issue new government contracts or fail to extend existing government contracts. Our ability to originate new assets could be adversely affected if one or more of the ESCOs or other origination sources with whom we have relationships are suspended or debarred or fail to win new, or renew existing, contracts. A change in the fiscal health, level of appropriations or budgets of U.S. federal, state and local governments could reduce demand for our investments. Although our energy efficiency investments do not normally require additional governmental appropriations to cover repayment due to the energy and operating savings derived from the newly installed equipment and systems, a significant decline in the fiscal health, level of appropriations or budgets of government customers may make it difficult for them to remain current on existing payment obligations or undesirable to enter into new energy efficiency improvement projects. Alternatively, some government entities may choose to provide appropriations or other credit support for climate solutions projects, which would negatively impact the use of private capital such as ours. This could have a material and adverse effect on the return of and return on our investments for existing projects and on our ability to originate new assets. Moreover, other changes in resources available to governments may also impact their willingness to undertake energy efficiency projects. For example, an increase in money set aside for government expenditures for energy efficiency projects may reduce demand for our investments. In addition, to the extent we make investments that involve direct appropriations, we will depend on approval of the necessary spending for the projects. The repayment of the investment, or the return on our asset, could be adversely affected if appropriations for any such projects are delayed or terminated. If the cost of energy generated by traditional sources of energy continues to stay or further declines from present levels, demand for the projects in which we invest may decline. Many traditional sources of energy such as coal, petroleum-based fuels and natural gas can be influenced by the price of underlying or substitute commodities. Such prices, which have decreased and may continue to decrease, may reduce the demand for energy efficiency projects or other projects, including renewable energy facilities, that do not rely on fossil fuel energy sources. For example, low natural gas prices may reduce the demand for projects like renewable energy that can substitute for natural gas, as well as adversely affect both the price available to renewable energy projects under future power sale agreements and the price of the electricity the projects sell on either a forward or a spot-market basis. Technological progress in electricity generation, storage or in the production of traditional fuels or the discovery of large new deposits of traditional fuels could reduce the cost of energy generated from those sources and consequently reduce the demand for the types of projects in which we invest, which could harm our new business origination prospects as well as the value of our existing Portfolio. In addition, volatility in commodity prices, including energy prices, may cause building owners and other parties to be reluctant to commit to projects for which repayment is based upon a fixed monetary value for energy savings that would not decline if the price of energy declines. Any resulting decline in demand for our investments or the price that industry participants receive for the sale of fossil fuel could adversely impact our operating results. If the market for various types of climate solutions projects or the investment techniques related to such projects do not develop as we anticipate, new business generation in this target area may be adversely impacted. The market for various types of climate solutions projects is emerging and rapidly evolving, leaving their future success uncertain. Similarly, various investing techniques, such as leasing land for renewable energy projects, purchasing interests in existing renewable energy projects, the use of C-PACE financing and the use of taxable debt for state and local energy efficiency or sustainable infrastructure financings are emerging and the future success of these investing techniques is also uncertain. If some or all market segments or investing techniques prove unsuitable for widespread commercial deployment or if demand for such projects or techniques fail to grow sufficiently, the demand for our capital may decline or develop more slowly than we anticipate. Many factors will influence the widespread adoption and demand for such projects and investing techniques, including general and local economic conditions, commodity prices of fossil fuel energy sources, the cost and availability of energy storage, the cost-effectiveness of various projects and techniques, performance and reliability of such technologies compared to conventional power sources and technologies, and the extent of government subsidies and regulatory developments. Any changes in the markets, products, technologies, financing techniques, or the regulatory environment could adversely impact the demand or financial performance for such projects and our investments. | 1 3 HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS Some projects in which we invest rely on net metering and related policies to improve project economics which if reduced could impact repayment of our investments or the return on our assets. There has been a nationwide increase in distributed generation which has prompted discussions among policy makers and regulators regarding ways to both better integrate distributed energy resources into the electric grid and how to compensate distributed generators. Many states have a regulatory policy known as net energy metering, or net metering. Net metering typically allows some project customers to interconnect their on-site solar or other renewable energy systems to the utility grid and offset their utility electricity purchases by receiving a bill credit at the utility’s retail rate for the amount of energy in excess of their electric usage that is generated by their renewable energy system and is exported to the grid. At the end of the billing period, the customer simply pays for the net energy used or receives a credit at the retail rate if more energy is produced than consumed. Net metering policies are under review or have been limited or amended in a number of states. The ability and willingness of customers to pay for renewable energy systems which benefit from net metering rules may be reduced if net metering rules are eliminated or their benefits reduced, which may also impact our returns on such systems. Existing electric utility industry regulations, and changes to regulations, may present technical, regulatory and economic barriers to the purchase and use of renewable energy and energy efficiency systems that may significantly reduce demand for systems and projects in which we invest or may adversely affect the profitability of such projects. Federal, state and local government regulations and policies concerning the electric utility industry, and internal policies and regulations promulgated by electric utilities, heavily influence the market for electricity products and services. These regulations and policies often relate to electricity pricing and the interconnection of customer- owned electricity generation. In the United States, governments and utilities continuously modify these regulations and policies. These regulations and policies could deter customers from purchasing energy efficiency and renewable energy systems. For example, Federal Energy Regulatory Commission (“FERC”) recently conducted its own review of grid resiliency and the functioning of electricity markets and has made, and could continue to make, changes to policies and regulations related to the function of the electricity markets and grid resiliency which may negatively impact the use of renewable energy or encourage the use of fossil fuel energy over renewable energy. This could result in a significant reduction in the potential demand for such systems. Utilities commonly charge fees to larger, industrial customers for disconnecting from the electric grid or for having the capacity to use power from the electric grid for back-up purposes. In addition, there is an increasing trend towards initiating or increasing fixed fees for users to have electricity service from a utility. These fees could increase our customers’ cost to use energy efficiency and renewable energy systems not supplied by the utility and make them less desirable, thereby harming our business, prospects, financial condition and results of operations. In addition, any changes to government or internal utility regulations and policies that favor electric utilities could reduce competitiveness and cause a significant reduction in demand for systems in which we invest. Further, certain climate solutions projects in which we invest may be “qualifying facilities” that are exempt from rate regulation as public utilities by FERC under the Federal Power Act, (the “FPA”). FERC regulations under the FPA confer upon these qualifying facilities key rights to interconnection with local utilities and can entitle such facilities to enter into PPAs with local utilities, from which the qualifying facilities benefit. Changes to these U.S. federal laws and regulations could increase the regulatory burdens and costs and could reduce the revenue of the project. In addition, modifications to the pricing policies of utilities could require climate solutions projects to achieve lower prices in order to compete with the price of electricity from the electric grid and may reduce the economic attractiveness of certain energy efficiency measures. To the extent that the projects in which we invest are subject to rate regulation, the project owners will be required to obtain FERC acceptance of their rate schedules for wholesale sales of energy, capacity and ancillary services. Any adverse changes in the rates project owners are permitted to charge could negatively impact the repayment of our investments, or the return on our assets. In addition, the operation of, and electrical interconnection for, our climate solutions projects may be subject to U.S. federal, state or local interconnection and federal reliability standards, some of which are set forth in utility tariffs. These standards and tariffs specify rules, business practices and economic terms to which the projects in which we invest are subject and that may impact a project’s ability to deliver the electricity it produces or transports to its end customer. The tariffs are drafted by the utilities and approved by the utilities’ state and U.S. federal regulatory commissions. These standards and tariffs change frequently and it is possible that future changes will increase our administrative burden or adversely affect the terms and conditions under which the projects render services to their customers. Under certain circumstances, we may also be subject to the reliability standards of the North American Electric Reliability Corporation. If project owners fail to comply with the mandatory reliability standards, they could be subject to sanctions, including substantial monetary penalties, which could also raise credit risks for, or lower the returns available from, the project companies in which we invest. These various regulations may also limit the transferability or sale of renewable energy projects and any such limits could negatively impact our returns from such projects. We are subject to risks related to our ESG activities and disclosures. Our ESG strategy and practices and the level of transparency with which we are approaching them are foundational to our business and expose us to several risks, including: z that we may fail or be unable to fully achieve one or more of our ESG goals due to a range of factors within or beyond our control, or that we may adjust or modify our goals in light of new information, adjusted projections, or a change in business strategy, which could negatively impact our reputation and our business; z that a failure to or perception of a failure to disclose metrics and set goals that are rigorous enough or in an acceptable format, a failure to appropriately manage selection of goals, a failure to or perception of a failure to make appropriate disclosures, stockholder perception of a failure to prioritize the “correct” ESG goals, or an unfavorable ESG-related rating by a third party, which could negatively impact our reputation and our business; 1 4 | HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS z that certain data we utilize in our CarbonCount or similar metric calculations is prepared by third parties or receives limited assurance from and/or verification by third parties and may undergo a less rigorous review process than assurance sought in connection with more traditional audits and such review process may not identify errors and may not protect us from potential liability under the securities laws, and, if errors are identified our reputation and our business could be negatively impacted and if we were to seek more extensive assurance or attestation with respect to such ESG metrics, we may be unable to obtain such assurance or attestation or may face increased costs related to obtaining and/or maintaining such assurance or attestation; z that the ESG or sustainability standards, norms, or metrics, which are constantly evolving, change in a manner that impacts us negatively or requires us to change the content or manner of our disclosures, and our stockholders or third parties view such changes negatively, we are unable to adequately explain such changes, or we are required to expend significant resources to update our disclosures, any of which could negatively impact our reputation and our business; and z that our business could be negatively impacted if any of our disclosures, including our CarbonCount or similar metrics, reporting to third-party ESG standards, or reporting against our goals, are inaccurate, perceived to be inaccurate, or alleged to be inaccurate. We operate in a competitive market and future competition may impact the terms of our investments. We compete against a number of parties who may provide alternatives to our investments including specialty finance companies, savings and loan associations, banks, private equity, hedge or infrastructure investment funds, insurance companies, mutual funds, institutional investors, investment banking firms, financial institutions, utilities, independent power producers, project developers, pension funds, government entities, public entities established to own infrastructure assets and other entities. The continued low interest rate environment and increasing investor acceptance of the climate solutions market have increased the level of competition we experience. We also encounter competition in the form of potential customers or our origination partners electing to use their own capital rather than engaging an outside provider such as us. In addition, we may also face competition based on technological developments that reduce demand for electricity, increase power supplies through existing infrastructure or that otherwise compete with our climate solutions projects. Some of our competitors are significantly larger than we are, have access to greater capital and other resources than we do and may have other advantages over us. In addition, some of our competitors may have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments and establish more relationships than we can. Further, many of our competitors are not subject to the operating constraints associated with REIT tax compliance or maintenance of an exemption from the 1940 Act. These characteristics could allow our competitors to consider a wider variety of opportunities, establish more relationships and offer better pricing and more flexible structuring than we can offer. We may lose business opportunities if we do not match our competitors’ pricing, terms and structure. If we match our competitors’ pricing, terms and structure, we may not be able to achieve acceptable risk-adjusted returns on our assets or we may be forced to bear greater risks of loss. The increase in the number or the size of our competitors in this market has resulted, and could continue to result, in less attractive terms on our investments or the need to accept a higher level of risks associated with our investments. As a result, competitive pressures we face could have a material adverse effect on our business, financial condition and results of operations. Our business is affected by seasonal trends and construction cycles, and these trends and cycles could have an adverse effect on our operating results. The volume and timing of our originations are subject to seasonal fluctuations and construction cycles, particularly in climates that experience colder weather during the winter months or at educational institutions, where large projects are typically carried out during summer months when their facilities are unoccupied. In addition, government customers, many of which have fiscal years that do not coincide with ours, typically follow annual procurement cycles. Further, government contracting cycles can be affected by the timing of, and delays in, the legislative process related to government programs, funding, or incentives that help drive demand for climate solutions projects. As a result of such fluctuations, we may occasionally experience fluctuations in the timing of new asset opportunities or declines in revenue or earnings as compared to the immediately preceding quarter, and comparisons of our operating results on a period-to-period basis may not be meaningful. Risks related to our assets and projects in which we invest Changes in interest rates could adversely affect the value of our assets and negatively affect our profitability. Interest rates are highly sensitive to many factors, including governmental monetary and tax policies, domestic and international economic and political considerations and other factors beyond our control. Many of our assets pay a fixed rate of interest or provide a fixed preferential return. With respect to our business operations, increases in interest rates, in general, may over time cause: (1) project owners to be less interested in borrowing or raising equity and thus reduce the demand for our investments; (2) the interest expense associated with our borrowings to increase; (3) the market value of our fixed rate or fixed return assets to decline; and (4) the market value of our interest rate swap agreements to increase. Decreases in interest rates, in general, may over time cause: (1) project owners to be more interested in borrowing or raising equity thus increase the demand for our assets; (2) prepayments on our assets, to the extent allowed, to increase; (3) the interest expense associated with our borrowings to decrease; (4) the market value of our fixed rate or fixed return assets to increase; and (5) the market value of our interest rate swap agreements to decrease. Adverse developments resulting from changes in interest rates could have a material adverse effect on our business, financial condition and results of operations. | 1 5 HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS The lack of liquidity of our assets may adversely affect our business, including our ability to value our assets. Volatile market conditions could significantly and negatively impact the liquidity of our assets. Illiquid assets typically experience greater price volatility, as a ready market does not exist, and can be more difficult to value. In addition, validating third-party pricing for illiquid assets may be more subjective than more liquid assets. The illiquidity of our assets may make it difficult for us to sell such assets if the need or desire arises. In addition, if we are required to liquidate all or a portion of our Portfolio quickly, we may realize significantly less than the value at which we have previously recorded our assets. To the extent that we utilize leverage to finance our investments that are or become illiquid, the negative impact on us related to trying to sell assets in a short period of time for cash could be greatly exacerbated. As a result, our ability to vary our Portfolio in response to changes in economic and other conditions may be relatively limited, which could adversely affect our results of operations and financial condition. Some of the assets in our Portfolio may be recorded at fair value and, as a result, there could be uncertainty as to the value of these assets. Further, we may experience a decline in the fair value of our assets. Our investments are not publicly traded. The fair value of assets that are not publicly traded may not be readily determinable. In accordance with GAAP, we record certain of our assets at fair value, which may include unobservable inputs. Because such valuations are subjective, the fair value of these assets may fluctuate over short periods of time and our determinations of fair value may differ materially from the values that would have been used if a ready market for these assets existed. The value of our common stock could be adversely affected if our determinations regarding the fair value of these assets were materially higher than the values that we ultimately realize upon their disposal. Additionally, our results of operations for a given period could be adversely affected if our determinations regarding the fair value of these assets were materially higher than the values that we ultimately realize upon their disposal. The valuation process can be particularly challenging during periods when market events make valuations of certain assets more difficult, unpredictable and volatile. A decline in the fair market value of any asset we carry at fair value, may require us to reduce the value of such assets under GAAP. In addition, our other financial assets are subject to an impairment assessment that could result in adjustments to their carrying values. Upon the subsequent disposition or sale of such assets, we could incur future losses or gains based on the difference between the sale price received and adjusted value of such assets as reflected on our balance sheet at the time of sale. The preparation of our financial statements, including provision for loan losses, involves use of estimates, judgments and assumptions, and our financial statements may be materially affected if our estimates prove to be incorrect. Financial statements prepared in accordance with GAAP require the use of estimates, judgments and assumptions that affect the reported amounts. Different estimates, judgments and assumptions reasonably could be used that would have a material effect on the financial statements, and changes in these estimates, judgments and assumptions are likely to occur from period to period in the future. Significant areas of accounting requiring the application of management’s judgment include but are not limited to determining the fair value of our assets. These estimates, judgments and assumptions are inherently uncertain, and, if they prove to be wrong, then we face the risk that charges to income will be required. Any charges could significantly harm our business, financial condition, results of operations and the price of our securities. See Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Use of Estimates for a discussion of the accounting estimates, judgments and assumptions that we believe are the most critical to an understanding of our business, financial condition and results of operations. Further, our provision for loan losses is evaluated on a quarterly basis. The determination of our provision for loan losses requires us to make certain estimates and judgments, which may be difficult to determine. Our estimates and judgments are based on a number of factors and may not be correct. If our estimates or judgments are incorrect, our results of operations and financial condition could be severely impacted. See Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Use of Estimates for a discussion of the accounting estimates, judgments and assumptions that we believe are the most critical to our provision of loan losses. We rely on our project sponsors for financial reporting related to our project companies, and our financial statements may be materially affected if the financial reporting related to our project companies proves to be incorrect. We have equity investments in climate solutions project companies which we account for under the equity method of accounting, which requires us to rely on the project sponsor for the reporting of the financial results of those project companies, including in some instances the allocation of earnings under the hypothetical liquidation at book value (“HLBV”) method. The HLBV method involves complex judgments around the interpretation of legal provisions governing liquidation of the entity in which we are invested. To the extent the reporting inclusive of these HLBV allocations we are provided is incorrect, our financial results reported using that information may be incorrect. The majority of our investments are not rated by a rating agency, which may result in an amount of risk, volatility or potential loss of principal that is greater than that of alternative asset opportunities. The majority of our investments are not rated by any rating agency and we expect that most of the assets we originate and acquire in the future will not be rated by any rating agency. Although we focus on climate solutions project companies with high credit quality obligors, we believe that some of the projects or obligors in which we invest, if rated, would be rated below investment grade, due to speculative characteristics of the project or the obligor’s capacity to pay interest and repay principal or pay dividends. Some of our assets may result in an amount of risk, volatility or potential loss of principal that is greater than that of alternative asset opportunities. 1 6 | HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS Any credit ratings assigned to our assets, debt or obligors are subject to ongoing evaluations and revisions and we cannot assure you that those ratings will not be downgraded. To the extent our assets, their underlying obligors, or our debt are rated by credit rating agencies or by our internal rating process, such assets, obligors or our debt will be subject to ongoing evaluation by credit rating agencies and our internal rating process, and we cannot assure you that any ratings will not be changed or withdrawn in the future. If rating agencies assign a lower-than-expected rating or if a rating is further reduced or withdrawn by a rating agency or us, or if there are indications of a potential reduction or withdrawal of the ratings of our assets, the underlying obligors or our debt in the future, the value of these assets could significantly decline, the level of borrowings based on such asset could be reduced or we could incur higher borrowing costs or incur losses upon disposition or the failure of obligors to satisfy their obligations to us. Our investments are subject to delinquency, foreclosure and loss, any or all of which could result in losses to us. Our investments are subject to risks of delinquency, foreclosure and loss. In many cases, the ability of a borrower to return our invested capital and our expected return is dependent primarily upon the successful development, construction and operation of the underlying project. If the cash flow of the project is reduced, the borrower’s ability to return our capital and our expected return may be impaired. We make certain estimates regarding project cash flows or savings during the underwriting of our investment. These estimates may not prove accurate, as actual results may vary from estimates. The cash flows or cost savings of a project can be affected by, among other things: the terms of the power purchase or other use agreements used in such project; the creditworthiness of the off-taker or project user; price of power or services now and in the future; the technology deployed; unanticipated expenses in the development or operation of the project and changes in national, regional, state or local economic conditions, laws and regulations; and acts of God, terrorism, social unrest and civil disturbances. In the event of any default or shortfall of an investment, we will bear a risk of loss of principal or equity to the extent of any deficiency between the value of the collateral, if any, and the amount of our investment, which could have a material adverse effect on our cash flow from operations and may impact the cash available for distribution to our stockholders. Many of the projects are structured as special purpose limited liability companies which limits our ability to realize any recovery to the collateral or value of the project itself. In the event of the bankruptcy of a project owner, obligor, or other borrower, our investment or the project will be deemed to be subject to the avoidance powers of the bankruptcy trustee or debtor-in-possession and our or the project’s contractual rights may be unenforceable under federal bankruptcy or state law. Foreclosure proceedings against a project can be an expensive and lengthy process, which could have a substantial negative effect on our anticipated return on the foreclosed investment. Our climate solutions project companies may incur liabilities that rank equally with, or senior to, our investments in such projects. We provide a range of investment structures, including various types of debt and equity securities, senior and subordinated loans, real property leases, mezzanine debt, preferred equity and common equity. Our projects may have, or may be permitted to incur, other liabilities or equity preferences that rank equally with, or senior to, our positions or investments in such projects or businesses, as the case may be, including with respect to grants of collateral. By their terms, such instruments may entitle the holders to receive payment of interest, principal payments or other distributions on or before the dates on which we are entitled to receive payments with respect to the instruments in which we invest. Also, in the event of insolvency, liquidation, dissolution, reorganization or bankruptcy of an entity in which we have invested, holders of instruments ranking senior to our investment in that project or business would typically be entitled to receive payment in full before we receive any distribution. After repaying such senior stakeholders, such project may not have any remaining assets to use for repaying its obligation to us. In the case of securities ranking equally with instruments we hold, we would have to share on an equal basis any distributions with other stakeholders holding such instruments in the event of an insolvency, liquidation, dissolution, reorganization or bankruptcy of the relevant project. Our subordinated and mezzanine debt and equity investments, many of which are illiquid with no readily available market, involve a substantial degree of risk. Subordinated and mezzanine debt and equity investments involve a number of significant risks, including: z such investments could be subject to further dilution as a result of the issuance of additional debt or equity interests and to additional risks because subordinated and mezzanine debt are subordinate to other indebtedness and in some cases, project tax equity, and equity interests are subordinate to all indebtedness (including trade creditors) and any senior securities in the event that the issuer is unable to meet its obligations or becomes subject to a bankruptcy process; z to the extent that a project company in which we invest requires additional capital and is unable to obtain it, we may not recover our investment; and z in some cases, subordinated and mezzanine debt may not pay current interest or principal or equity investments may not pay current dividends, and our ability to realize a return on our investment, as well as to recover our investment, will be dependent on the success of the project company in which we invest. The project may face unanticipated costs or delays or may not generate projected cash flows which could lead to the project generating lower than expected rates of return. We generally do not control the projects in which we invest. Although the covenants in our financing or investment documentation generally restrict certain actions that may be taken by project owners, we generally do not control the projects in which we invest. As a result, we are subject to the risk that the project owner may make certain business decisions or take risks with which we disagree or otherwise act in ways that do not serve our interests. We invest in joint ventures and other similar arrangements that subject us to additional risks. Some of our project companies are structured as joint ventures, partnerships, securitizations, syndications and consortium arrangements. Part of our strategy is to participate with other institutional investors or the project’s sponsor on various climate solutions transactions. | 1 7 HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS These arrangements are driven by the magnitude of capital required to complete acquisitions and the development of climate solutions projects and other industry-wide trends that we believe will continue. Such arrangements involve risks not present where a third party is not involved, including the possibility that partners or co-venturers might become bankrupt or otherwise fail to fund their share of required capital contributions. Additionally, partners or co-venturers might at any time have economic or other business interests or goals different from ours. These investments generally provide for a reduced level of control over an acquired project because governance rights are shared with others. Accordingly, project decisions relating to the management, operation and the timing and nature of any exit, are often made by a majority vote of the investors or by separate agreements that are reached with respect to individual decisions. In addition, project operations may be subject to the risk that the project owners may make business, financial or management choices with which we do not agree or the management of the project may take risks or otherwise act in a manner that does not serve our interests. Because we may not have the ability to exercise control, we may not be able to realize some or all of the benefits expected from our investment. If any of the foregoing were to occur, our business, financial condition and results of operations could suffer as a result. In addition, some of our joint ventures, partnerships, and equity investments, subject the sale or transfer of our interests in these project companies to rights of first refusal or first offer, tag along or drag along rights and buy-sell, call-put or other restrictions. Such rights may be triggered at a time when we may not want them to be exercised and such rights may inhibit our ability to sell our interest in an entity within our desired time frame or on any other desired terms. Many of our assets depend on revenues from third-party contractual arrangements. Many of the projects in which we invest rely on revenue or repayment from contractual commitments of end-customers, including federal, state, or local governments for energy efficiency projects or utilities or other customers under PPAs. There is a risk that these customers may default under their contracts. In addition, many of these end-customers are large entities with wide ranging activities. An event in a non-related part of the business could have a material adverse impact on the financial strength of such end-customer, such as the effect of recent wildfires on the California utilities. Furthermore, the bankruptcy, insolvency, or other liquidity constraints of one or more customers may result in a renegotiation or rejection of the third-party contract, delay the receipt of any obligations or reduce the likelihood of collecting defaulted obligations. Some projects rely on one customer for their revenue and thus the project could be materially and adversely affected by any material change in the financial condition of that customer. While there may be alternative customers for such a project, there can be no assurance that a new contract on the same terms will be able to be negotiated for the project. Certain of our projects with contractually committed revenues or other sources of repayment under long term contracts will be subject to re- contracting risk in the future. We cannot provide assurance that these contracts can be re-negotiated once their terms expire on equally favorable terms or at all. If it is not possible to renegotiate these contracts on favorable terms, our business, financial condition, results of operations, and prospects could be materially and adversely affected. Revenues at some of the projects in which we invest depend on reliable and efficient metering, or other revenue collection systems, which are often specified in the contract. If one or more of such projects are not able to operate and maintain the metering or other revenue collection systems in the manner expected, if the operation and maintenance costs, are greater than expected, or if the customer disputes the output of the revenue collection system, the ability of the project to repay our investments or provide a return to us on our asset could be materially and adversely affected. We are exposed to the credit risk of ESCOs, various project sponsors, and others. We are subject to varying degrees of credit risk related to ESCOs in government energy efficiency projects in which guarantees provided by ESCOs under energy savings performance contracts are required in the event that certain energy savings are not realized by the customer. We are also exposed to credit risk in projects in which we invest that do not depend on funding from governments. Where we make loans to or own equity interests in special purposes entities such as those that lease solar energy systems to residential customers, those special purpose entities often enter into various contractual arrangements with, or receive performance guarantees from the affiliate project sponsor to ensure satisfactory equipment or other project performance over the term of the lease or power purchase agreement. To the extent those parties are unable to perform on their contractual obligations or performance guarantees we may see diminished equity returns or the special purpose entity may be unable to repay their loan timely or at all. We seek to mitigate these credit risks by employing a comprehensive review and asset selection process and careful ongoing monitoring of acquired assets. Nevertheless, unanticipated credit losses could occur which could adversely impact our operating results. During periods of economic downturn in the global economy, the solvency and financial wherewithal of counterparties with whom we do business could be impacted and our exposure to credit risks from obligors increases, and our efforts to monitor and mitigate the associated risks may not be effective in reducing our credit risks. In the event a counterparty to us or one of our climate solutions projects becomes insolvent or unable to make payments, we may fail to recover the full value of our investment or realize the value from the counterparty’s contract, thus reducing our earnings and liquidity. In addition, the insolvency of one or more of our, or one of our climate solutions projects’, counterparties could reduce the amount of financing available to us, which would make it more difficult for us to leverage the value of our assets and obtain substitute financing on attractive terms or at all. A material reduction in our financing sources or an adverse change in the terms of our financings could have a material adverse effect on our financial condition and results of operations. Certain participants in the sustainable energy industry have experienced significant declines in the value of their equity and difficulty in raising or refinancing debt, which increases the credit risk to these companies and there can be no assurance they will be able to fulfill their obligations which could adversely impact our operating results. Some of the projects in which we invest have sold their output under PPAs that expose the projects to various risks. Some of our projects enter into PPAs when they contract to sell all or a fixed proportion of the electricity generated by the project, sometimes bundled with renewable energy credits and capacity or 1 8 | HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS other environmental attributes, to a power purchaser, often a utility, or increasingly, a corporation. PPAs are used to stabilize our revenues from that project. We are exposed to the risk that the power purchaser, who we consider an obligor, will fail to perform under a PPA or the PPA will be terminated or expire, which will lead to that project needing to sell its electricity at the then market price, which could be substantially lower than the price provided in the applicable PPA. In most instances, the project also commits to sell minimum levels of generation. If the project generates less than the committed volumes, it may be required to buy the shortfall of electricity on the open market or make payments of liquidated damages or be in default under a PPA, which could result in its termination. In the event that any of these events were to occur, our business, financial condition, and results of operations could suffer as a result. Portions of the electricity and environmental attributes our assets generate are sold on the open market at spot-market prices. A prolonged environment of low prices for natural gas, or other conventional fuel sources such as we are experiencing may, and could continue to, have a material adverse effect on our long-term business prospects, financial condition and results of operations. Low prices for traditional fossil fuels, particularly natural gas, could cause demand for renewable energy to decrease and prices have, and may continue to, adversely affect both the future sale price of energy under new PPAs and the current sale price of energy sold on a spot-market basis. Low PPA and spot market power prices, if combined with other factors, can have a material adverse effect on our projects and their respective values and our expected returns, results of operations and cash available for distribution. Some of the projects we invest in, or may plan to invest in, sell environmental attributes such as renewable energy credits or other similar credits on an uncontracted basis. To the extent merchant prices for these attributes are lower than expected, our projects revenues could be adversely impacts, and our business, financial condition, and results of operations could suffer as a result. The ability of our assets to generate revenue from certain projects depends on having interconnection arrangements and services. The future success of our assets will depend, in part, on their ability to maintain satisfactory interconnection agreements. If the interconnection or transmission agreement of a project is terminated for any reason, they may not be able to replace it with an interconnection and transmission arrangement on terms as favorable as the existing arrangement, or at all, or they may experience significant delays or costs in connection with securing a replacement. If a network to which one or more of the projects is connected experiences equipment or operational problems or other forms of “down time,” the affected project may lose revenue and be exposed to non-performance penalties and claims from its customers. These may include claims for damages incurred by customers, such as the additional cost of acquiring alternative electricity supply at then-current spot market rates. The owners of the network will not usually compensate electricity generators for lost income due to down time. In addition, our projects may be exposed to a locational basis risk resulting from a difference between where the power is generated and the contracted delivery point. These factors could materially affect these projects, which could negatively affect our business, results of operations, financial condition, and cash flow. Our projects and their obligors are exposed to an increase in climate change or other change in meteorological conditions which could have an impact on electric generation, revenue, insurance costs or the ability of the projects or their obligors to honor their contract obligations, all of which could adversely affect our business, financial condition and results of operations and cash flows. The electricity produced and revenues generated by a renewable electric generation facility are highly dependent on suitable weather conditions, which are beyond our control. Components of renewable energy systems, such as turbines, solar panels and inverters, could be damaged by natural disasters or severe weather, including extreme temperatures, wildfires, hurricanes, hailstorms or tornadoes. Furthermore, the potential physical impacts of climate change may impact our projects, including the result of changes in weather patterns (including floods, tsunamis, drought, and rainfall levels), wind speeds, water availability, storm patterns and intensities, and temperature levels. The projects in which we invest will be obligated to bear the expense of repairing the damaged renewable energy systems and replacing spare parts for key components and insurance may not cover the costs or the lost revenue. Natural disasters or unfavorable weather and atmospheric conditions, such as extreme cold temperatures impacting Texas in February 2021, could impair the effectiveness of the renewable energy assets, reduce their output beneath their rated capacity, require shutdown of key equipment or impede operation of the renewable energy assets, which could adversely affect our business, financial condition and results of operations and cash flows. Sustained unfavorable weather could also unexpectedly delay the installation of renewable energy systems, which could result in a delay in our investing in new projects or increase the cost of such projects. The resulting effects of climate change can also have an impact on the cost of, and the ability of a project to obtain, adequate insurance coverage to protect against related losses. We typically base our investment decisions with respect to each renewable energy facility on the findings of studies conducted on-site prior to construction or based on historical conditions at existing facilities. However, actual climatic conditions at a facility site may not conform to the findings of these studies. Even if an operating project’s historical renewable energy resources are consistent with the long-term estimates, the unpredictable nature of weather conditions often results in daily, monthly and yearly material deviations from the average renewable resources anticipated during a particular period. Therefore, renewable energy facilities in which we invest may not meet anticipated production levels or the rated capacity of the generation assets, which could adversely affect our business, financial condition and results of operations and cash flows. In addition, many of the project’s end-customers are large entities with wide ranging activities. A climate related event in a non-related part of the business could have a material adverse impact on the financial strength of such end-customer and their ability to honor their contractual obligations which could negatively impact on revenue and the cash flow of the project and our business. | 1 9 HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS Operation of the projects in which we invest involves significant risks and hazards that could have a material adverse effect on our business, financial condition, results of operations and cash flows. Climate projects are subject to various construction and operating delays and risks that have in the past caused them to, and may in the future cause them to, incur higher than expected costs or generate less than expected amounts of savings or outputs, such as electricity in the case of a renewable energy project. The ongoing operation of the projects in which we invest involves risks that include construction delays, the breakdown or failure of equipment or processes or performance below expected levels of output or efficiency due to wear and tear, latent defect, design error or operator error or force majeure events, among other things. In addition to natural risks such as earthquake, flood, drought, lightning, wildfire, hurricane, ice, wind, and temperature extremes, other hazards, such as fire, explosion, structural collapse and machinery failure, acts of terrorism or related acts of war, hostile cyber intrusions, pandemics, or other catastrophic events are inherent risks in the construction and operation of a project. These and other hazards can cause significant personal injury or loss of life, severe damage to and destruction of property, plant and equipment and contamination of, or damage to, the environment and suspension of operations. Operation of a project also involves risks that the operator will be unable to transport its product to its customers in an efficient manner due to a lack of transmission capacity. Unplanned outages of projects, including extensions of scheduled outages due to mechanical failures or other problems, occur from time to time and are an inherent risk of the business. Unplanned outages typically increase operation and maintenance expenses and may reduce revenues as a result of selling less electricity or require the project to incur significant costs as a result of obtaining replacement power from third parties in the open market to satisfy forward power sales obligations. Any extended interruption in a project’s construction or operation, a project’s inability to operate its assets efficiently, manage capital expenditures and costs and generate earnings and cash flow could have a material adverse effect on the repayment of and return on our investment and our business, financial condition, results of operations and cash flows. While the projects maintain insurance, obtain warranties from vendors and obligate contractors to meet certain performance levels, the proceeds of such insurance, warranties or performance guarantees may not cover the lost revenues, increased expenses or liquidated damages payments should the project experience any equipment breakdowns, insurance claims or non-performance by contractors or vendors. Some of the projects in which we invest may require substantial operating or capital expenditures in the future. Many of the projects in which we invest are capital intensive and require substantial ongoing expenditures for, among other things, additions and improvements, and maintenance and repair of plant and equipment related to project operations. In addition, there may be cash needs to settle certain contractual obligations of the projects, such as settlements or margining requirements related to hedging activities. While we do not typically bear the responsibility for these expenditures, any failure by the equity owner to make necessary operating or capital expenditures could adversely impact project performance. In addition, some of these expenditures may not be recoverable from current or future contractual arrangements. The use of real property rights that we acquire or are used for our climate solutions projects may be adversely affected by the rights of lienholders and leaseholders that are superior to those of the grantors of those real property rights to us. The projects in which we invest often require large areas of land for construction and operation or other easements or access to the underlying land. In addition, we may acquire rights to land or other real property. Although we believe that we, or our projects in which we invest, have valid rights to all material easements, licenses and rights of way, not all of such easements, licenses and rights of way are registered against the lands to which they relate and may not bind subsequent owners. Some of our real property rights and projects generally are, and are likely to continue to be, located on land occupied pursuant to long-term easements and leases. The ownership interests in the land subject to these easements and leases may be subject to mortgages securing loans or other liens (such as tax liens) and other easement and lease rights of third parties (such as leases of water, oil or mineral rights) that were created prior to, or are superior to, our or our projects’ easements and leases. As a result, our rights may be subject, and subordinate, to the rights of those third parties. We typically obtain representations or perform title searches or obtain title insurance to protect our real property interest and our investments in our projects against these risks. Such measures may, however, be inadequate to protect against all risk of loss of rights to use the land rights we have acquired or the land on which these projects are located, which could have a material and adverse effect on our land rights, our projects and their financial condition and operating results. We own land or leasehold interests that are used by renewable energy projects. Negative market conditions or adverse events affecting tenants, or the industries in which they operate, could have an adverse impact on our underwritten returns. Moreover, many of our real estate assets are concentrated in similar geographic locations, which subjects us to an increased risk of significant loss if any property declines in value, incurs a natural disaster or if we are unable to lease a property. We own land or leasehold interests used by renewable energy projects that are concentrated in a limited number of geographic locations. One consequence of this is that the aggregate returns we realize may be substantially adversely affected by the unfavorable performance of a small number of leases, a significant decline in the market value of any single property or a natural disaster in a concentrated area. Our cash flow depends in part on the ability to lease the real estate to projects or other tenants on economically favorable terms. We could be adversely affected by various facts and events over which we have limited or no control, such as: z lack of demand in areas where our properties are located; z inability to retain existing tenants and attract new tenants; z oversupply of space and changes in market rental rates; z our tenants’ creditworthiness and ability to pay rent, which may be affected by their operations, the current economic situation and competition within their industries from other operators; z defaults by and bankruptcies of tenants, failure of tenants to pay rent on a timely basis, or failure of tenants to comply with their contractual obligations; 2 0 | HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS z economic or physical decline of the areas where the properties are located; and z destruction from natural disasters. At any time, any tenant may experience a downturn in its business, including increased operating costs, termination of a PPA or low spot- market prices of products, that may weaken its operating results or overall financial condition, a tenant may delay lease commencement, fail to make rental payments when due, decline to extend a lease upon its expiration, become insolvent or declare bankruptcy. Any tenant bankruptcy or insolvency, leasing delay or failure to make rental payments when due could result in the termination of the tenant’s lease and material losses to us. If a tenant elects to terminate its lease prior to or upon its expiration or does not renew its lease as it expires, we may not be able to rent or sell the properties or realize our expected value. Furthermore, leases that are renewed and some new leases for properties that are re-leased, may have terms that are less economically favorable than expiring lease terms, or may require us to incur significant costs, such as lease transaction costs. In addition, negative market conditions or adverse events affecting tenants, or the industries in which they operate, may force us to sell vacant properties for less than their carrying value, which could result in impairments. Any of these events could adversely affect the value of our asset, the cash flow from operations and our ability to make distributions to stockholders and service indebtedness. A significant portion of the costs of owning property, such as real estate taxes, insurance and maintenance, are not necessarily reduced when circumstances cause a decrease in rental revenue from the properties. In a weakened financial condition, tenants may not be able to pay these costs of ownership and we may be unable to recover these operating expenses from them. Further, the occurrence of a tenant bankruptcy or insolvency could diminish the income we receive from the tenant’s lease or leases. For instance, a bankruptcy court might authorize the tenant to terminate its leases with us. If that happens, our claim against the bankrupt tenant for unpaid future rent would be subject to statutory limitations that most likely would be substantially less than the remaining rent we are owed under the leases. In addition, any claim we have for unpaid past rent, if any, may not be paid in full. As a result, tenant bankruptcies may have a material adverse effect on our results of operations. In addition, since renewable energy projects are often concentrated in certain states, we would also be subject to any adverse change in the political or regulatory climate in those states or specific counties where such properties are located that could adversely affect our properties and our ability to lease such properties. Performance of projects where we invest may be harmed by future labor disruptions and economically unfavorable collective bargaining agreements. A number of the projects where we invest could have workforces that are unionized or that in the future may become unionized and, as a result, are required to negotiate the wages, benefits and other terms with many of their employees collectively. If these projects were unable to negotiate acceptable contracts with any of their unions as existing agreements expire, they could experience a significant disruption of their operations, higher ongoing labor costs and restrictions on their ability to maximize the efficiency of their operations, which could have a material and adverse effect on our business, financial condition and results of operations. In addition, in some jurisdictions where our projects have operations, labor forces have a legal right to strike which may have a negative impact on our business, financial condition and results of operations, either directly or indirectly, for example if a critical upstream or downstream counterparty was itself subject to a labor disruption which impacted the ability of our projects to operate. We invest in projects that rely on third parties to manufacture quality products or provide reliable services in a timely manner and the failure of these third parties could cause project performance to be adversely affected. We invest in projects that typically rely on third parties to select, manage or provide equipment or services. Third parties may be responsible for choosing vendors, including equipment suppliers and subcontractors. Project success often depends on third parties who are capable of installing and managing projects and structuring contracts that provide appropriate protection against construction and operational risks. In many cases, in addition to contractual protections and remedies, project owners may seek guaranties, warranties and construction bonding to provide additional protection. The warranties provided by the third parties and, in some cases, their subcontractors, typically limit any direct harm that results from relying on their products and services. However, there can be no assurance that a supplier or subcontractor will be willing or able to fulfill its contractual obligations and make necessary repairs or replace equipment. In addition, these warranties generally expire within one to five years or may be of limited scope or provide limited remedies. If projects are unable to avail themselves of warranty protection or receive the expected protection under the terms of the guaranties or bonding, we may need to incur additional costs, including replacement and installation costs, which could adversely impact our investment. In addition, renewable energy projects rely on electric and other types of transmission lines and facilities owned and operated by third parties to receive and distribute their energy. Any substantial access barriers to these lines and facilities could adversely impact the demand or financial performance for such projects and our investments. Liability relating to environmental matters may impact the value of properties that we may acquire or the properties underlying our assets. Under various U.S. federal, state and local laws, an owner or operator of real estate or a project may become liable for the costs of removal of certain hazardous substances released from the project or any underlying real property. These laws often impose liability without regard to whether the owner or operator knew of, or was responsible for, the release of such hazardous substances. The presence of hazardous substances may adversely affect our, or another owner’s, ability to sell a contaminated project or borrow using the project as collateral. To the extent that we, or another project owner, become liable for removal costs, our investment, or the ability of the owner to make payments to us, may be negatively impacted. | 2 1 HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS We acquire real property rights, make investments in projects that own real property, have collateral consisting of real property and in the course of our business, we may take title to a project or its underlying real estate assets relating to one of our debt financings. In these cases, we could be subject to environmental liabilities with respect to these assets. To the extent that we become liable for the removal costs, our results of operation and financial condition may be adversely affected. The presence of hazardous substances, if any, may adversely affect our ability to sell the affected real property or the project and we may incur substantial remediation costs, thus harming our financial condition. Our insurance and contractual protections may not always cover lost revenue, increased expenses or liquidated damages payments. Although our assets or projects generally have insurance, supplier warranties, subcontractors performance assurances such as bonding and other risk mitigation measures, the proceeds of such insurance, warranties, bonding or other measures may not be adequate to cover lost revenue, increased expenses or liquidated damages payments that may be required in the future. Risks related to our company We may change our operational policies (including our investment guidelines and strategies) with the approval of our Board but without stockholder consent at any time, which may adversely affect the market value of our common stock and our ability to make distributions to our stockholders. Our board of directors determines our operational policies and may amend or revise our policies, including our policies with respect to acquisitions, dispositions, growth, operations, compensation, indebtedness, capitalization and dividends, or approve transactions that deviate from these policies, without a vote of, or notice to, our stockholders at any time. We may change our investment guidelines, underwriting process and our strategy at any time with the approval of our Board, but without the consent of our stockholders, which could result in originating assets that are different in type from, and possibly riskier than, the assets initially contemplated. In addition, our charter provides that our Board may authorize us to revoke or otherwise terminate our REIT election, without the approval of our stockholders, if it determines that it is no longer in our best interests to qualify as a REIT. These changes could adversely affect our business, financial condition, results of operations and our ability to make distributions to our stockholders. Our management and employees depend on information systems and system failures could significantly disrupt our business, which may, in turn, negatively affect the market price of our common stock and our ability to make distributions to our stockholders. Our underwriting process and our asset and financial management and reporting are dependent on our present and future communications and information systems. Any failure or interruption of these systems could cause delays or other problems in our originating, financing, investing, asset and financial management and reporting activities, which could have a material adverse effect on our operating results. 2 2 | The repayment of certain of our assets is dependent upon collection of payments from residential customers and we may be indirectly subject to consumer protection laws and regulations. Certain obligors to which we have credit exposure are, or may be, subject to consumer protection laws, such as federal truth-in-lending, consumer leasing, and equal credit opportunity laws and regulations, as well as state and local sales and finance laws and regulations. Claims arising out of actual or alleged violations of law may be asserted against those obligors by individuals or governmental entities and may exposure them to significant damages or other penalties, including fines, or could reduce the likelihood the residential customer may pay their obligation, which could limit their ability to repay borrowings or make equity distributions to us. We contract with information technology service providers where, in part, we rely upon their systems and controls for the quality of the data provided. The inappropriate establishment and maintenance of these systems and controls could cause information that we use to operate our business to be unavailable or inaccurate and could negatively impact our financial results. Our information technology architecture is partially outsourced. These systems and processes may be either internet based or through traditional outsourced functions and certain of these arrangements are new or emerging. When we contract with these service providers we attempt to evaluate the quality of their systems and controls before we execute the arrangement and may rely on third party reviews and audits of these service providers and attempt to implement certain processes to ensure the quality of the data received from these service providers. Because of the nature and maturity of the technology such efforts may be unsuccessful or incomplete and the unavailability of these systems or the inaccurate data provided from these service providers could negatively impact our financial results. Cybersecurity risks and cyber incidents may adversely affect our business by causing a disruption to our operations, a compromise or corruption of our confidential information, a misappropriation of funds, and/or damage to our business relationships, all of which could negatively impact our financial results. A cyber incident is considered to be any adverse event that threatens the confidentiality, integrity or availability of our information resources. These incidents may be an intentional attack or an unintentional event and could involve gaining unauthorized access to our information systems for purposes of misappropriating assets, stealing confidential information, corrupting data or causing operational disruption. The risk of a security breach or disruption, particularly through cyber-attacks or cyber intrusions, including by computer hackers, nation-state affiliated HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS United States in the future. These operations will be subject to a variety of risks that we do not face in the United States, including risk from changes in foreign country regulations, infrastructure, legal systems and markets. Other risks include possible difficulty in repatriating overseas earnings and fluctuations in foreign currencies. Our overall success in international markets will depend, in part, on our ability to succeed in different legal, regulatory, economic, social and political conditions. We may not be successful in developing and implementing policies and strategies that will be effective in managing these risks in each country where we decide to do business. Our failure to manage these risks successfully could harm our international projects, reduce our international income or increase our costs, thus adversely affecting our business, financial condition and operating results. We grow our business in part through future acquisitions or other similar investments. As we grow our business, we have used, and will continue to use, acquisitions of, or other types of transactions such as equity or convertible debt investments in, companies or assets to invest in new or different projects or markets, expand our project skill-sets and capabilities, expand our geographic markets, add experienced management and increase our product and service offerings. There are a number of risks associated with these transactions and we may not achieve our goals in the transaction. Such transaction could disrupt our business, cause dilution to our stockholders and harm our business, financial condition or operating results. In addition, the time and effort involved to identify candidates and consummate such transactions may divert members of our management from the operations of our company. actors, and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. The result of these incidents may include disrupted operations, misstated or unreliable financial data, disrupted market price of our common stock, misappropriation of assets, liability for stolen assets or information, increased cybersecurity protection and insurance cost, regulatory enforcement, litigation and damage to our relationships. These risks require continuous and likely increasing attention and other resources from us to, among other actions, identify and quantify these risks, upgrade and expand our technologies, systems and processes to adequately address them and provide periodic training for our employees to assist them in detecting phishing, malware and other schemes. Such attention diverts time and other resources from other activities and there is no assurance that our efforts will be effective. Potential sources for disruption, damage or failure of our information technology systems include, without limitation, computer viruses, security breaches, human error, cyber- attacks, natural disasters and defects in design. Additionally, due to the size and nature of our company, we rely on third-party service providers for many aspects of our business. We can provide no assurance that the networks and systems that our third-party vendors have established or use will be effective. As our reliance on technology has increased, so have the risks posed to both our information systems and those provided by third-party service providers. Our processes, procedures and internal controls that are designed to mitigate cybersecurity risks and cyber intrusions do not guarantee that a cyber incident will not occur or that our financial results, operations or confidential information will not be negatively impacted by such an incident. We may seek to expand our business internationally, which will expose us to additional risks that we do not face in the United States, which could have an adverse effect on our business, financial condition and operating results. We generate substantially all of our revenue from operations in the United States. We may seek to expand our projects outside of the Risks relating to regulation We cannot predict the unintended consequences and market distortions that may stem from far-ranging governmental intervention in the economic and financial system or from regulatory reform of the oversight of financial markets. The U.S. federal government, the Federal Reserve Board of Governors, the U.S. Treasury, the SEC, U.S. Congress and other governmental and regulatory bodies have taken, are taking or may in the future take, various actions to address financial crises or other areas of regulatory concern. Such actions could have a dramatic impact on our business, results of operations and financial condition, and the cost of complying with any additional laws and regulations or the elimination or reduction in scope of various existing laws and regulations could have a material adverse effect on our financial condition and results of operations. The far-ranging government intervention in the economic and financial system may carry unintended consequences and cause market distortions. We are unable to predict at this time the extent and nature of such unintended consequences and market distortions, if any. The inability to evaluate the potential impacts could have a material adverse effect on the operations of our business. Loss of our 1940 Act exemptions would adversely affect us, the market price of shares of our common stock and our ability to distribute dividends. We conduct our operations so that we are not required to register as an investment company under the 1940 Act. Section 3(a)(1)(A) of the 1940 Act defines an investment company as any issuer that is or holds itself out as being engaged primarily in the business of investing, reinvesting or trading in securities. Section 3(a)(1)(C) of the 1940 Act defines an investment company as any issuer that is engaged or proposes to engage in the business of investing, reinvesting, owning, holding or trading in securities and owns or proposes to acquire investment securities having a value exceeding 40% of the value of the issuer’s total assets (exclusive of U.S. Government securities and cash items) on a non-consolidated basis, which we refer to as the 40% test. Excluded from the term “investment securities,” among other things, are U.S. Government securities and securities issued by majority-owned subsidiaries that are not themselves investment companies and are not relying on the exemption from the definition of investment company set forth in Section 3(c)(1) or Section 3(c)(7) of the 1940 Act. | 2 3 HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS We conduct our businesses primarily through our subsidiaries and our operations so that we comply with the 40% test. The securities issued by any wholly-owned or majority-owned subsidiaries that we hold or may form in the future that are exempted from the definition of “investment company” based on Section 3(c)(1) or 3(c)(7) of the 1940 Act, together with any other investment securities we may own, may not have a value in excess of 40% of the value of our total assets on a non-consolidated basis. Certain of our subsidiaries rely on or will rely on an exemption from registration as an investment company under the 1940 Act pursuant to Section 3(c)(5)(C) of the 1940 Act, which is available for entities which are not primarily engaged in issuing redeemable securities, face-amount certificates of the installment type or periodic payment plan certificates and which are primarily engaged in the business of purchasing or otherwise acquiring mortgages and other liens on and interests in real estate. This exemption generally requires that at least 55% of such subsidiaries’ portfolios must be comprised of qualifying assets and at least 80% of each of their portfolios must be comprised of qualifying assets and real estate-related assets under the 1940 Act. Consistent with guidance published by the SEC staff, we intend to treat as qualifying assets for this purpose loans secured by projects for which the original principal amount of the loan did not exceed 100% of the value of the underlying real property portion of the collateral when the loan was made. We intend to treat as real estate-related assets non- controlling equity interests in joint ventures that own projects whose assets are primarily real property. In general, with regard to our subsidiaries relying on Section 3(c)(5)(C), we rely on other guidance published by the SEC or its staff or on our analyses of guidance published with respect to other types of assets to determine which assets are qualifying real estate assets and real estate-related assets. In addition, one or more of our subsidiaries qualifies for an exemption from registration as an investment company under the 1940 Act pursuant to either Section 3(c)(5)(A) of the 1940 Act, which is available for entities which are not engaged in the business of issuing redeemable securities, face-amount certificates of the installment type or periodic payment plan certificates, and which are primarily engaged in the business of purchasing or otherwise acquiring notes, drafts, acceptances, open accounts receivable, and other obligations representing part or all of the sales price of merchandise, insurance, and services, or Section 3(c)(5)(B) of the 1940 Act, which is available for entities primarily engaged in the business of making loans to manufacturers, wholesalers, and retailers of, and to prospective purchasers of, specified merchandise, insurance, and services. These exemptions generally require that at least 55% of such subsidiaries’ portfolios must be comprised of qualifying assets that meet the requirements of the exemption. We intend to treat energy efficiency loans where the loan proceeds are specifically provided to finance equipment, services and structural improvements to properties and other facilities and renewable energy and other climate solutions projects or improvements as qualifying assets for purposes of these exemptions. In general, we also expect, with regard to our subsidiaries relying on Section 3(c)(5)(A) or (B), to rely on guidance published by the SEC or its staff, including reliance on a no-action letter obtained in connection with Sections 3(c)(5)(A) and 3(c)(5)(B) of the 1940 Act, or on our analyses of guidance published with respect to other types of assets to determine which assets are qualifying assets under the exemptions. Although we monitor the portfolios of our subsidiaries relying on the Section 3(c)(5)(A), (B) or (C) exemptions periodically and prior to each acquisition, there can be no assurance that such subsidiaries will be able to maintain their exemptions. Qualification for exemptions from registration under the 1940 Act will limit our ability to make certain investments. For example, these restrictions will limit the ability of these subsidiaries to make loans that are not secured by real property or that do not represent part or all of the sales price of merchandise, insurance, and services. There can be no assurance that the laws and regulations governing the 1940 Act, including the Division of Investment Management of the SEC providing more specific or different guidance regarding these exemptions, will not change in a manner that adversely affects our operations. For example, on August 31, 2011, the SEC issued a concept release (No. IC-29778; File No. SW7-34-11, Companies Engaged in the Business of Acquiring Mortgages and Mortgage-Related Instruments) pursuant to which it is reviewing the scope of the exemption from registration under Section 3(c)(5)(C) of the 1940 Act. While the SEC has yet to provide additional information on its position relating to these exemptions and timing of any future changes to the exemptions remain unknown, any additional guidance from the SEC or its staff from this process or in other circumstances could provide additional flexibility to us, or it could further inhibit our ability to pursue the strategies we have chosen. If we or our subsidiaries fail to maintain an exemption from the 1940 Act, we could, among other things, be required either to (1) change the manner in which we conduct our operations to avoid being required to register as an investment company, (2) effect sales of our assets in a manner that, or at a time when, we would not otherwise choose to do so or (3) register as an investment company, any of which could negatively affect our business, our ability to make distributions, our financing strategy and the market price for our shares of common stock. We have not requested the SEC or its staff to approve our treatment of any company as a majority-owned subsidiary and neither the SEC nor its staff has done so. If the SEC or its staff were to disagree with our treatment of one or more companies as majority-owned subsidiaries, we would need to adjust our strategy and our assets in order to continue to pass the 40% test. Any such adjustment in our strategy could have a material adverse effect on us. Rapid changes in the values of our assets may make it more difficult for us to maintain our qualification as a REIT or our exemption from the 1940 Act. If the market value or income potential of our assets changes as a result of changes in interest rates, general market conditions, government actions or other factors, we may need to adjust the portfolio mix of our real estate assets and income or liquidate our non-qualifying assets to maintain our REIT qualification or our exemption from the 1940 Act. If changes in asset values or income occur quickly, this may be especially difficult to accomplish. This difficulty may be exacerbated by the illiquid nature of the assets we may own. We may have to make decisions that we otherwise would not make absent the REIT and 1940 Act considerations. Because we expect to distribute substantially all of our REIT taxable income to our stockholders, we will need additional capital to finance our growth and such capital may not be available on favorable terms or at all. We will need additional capital to fund our growth. U.S. federal income tax law generally requires that a REIT distribute annually at least 90% of its REIT taxable income, without regard to the deduction for dividends paid and excluding net capital gains, and that it pay tax at regular corporate rates to the extent that it annually distributes 2 4 | HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS greater than 90% but less than 100% of such REIT taxable income. Because we intend to grow our business, this limitation may require us to incur additional debt or raise additional equity at a time when it may be disadvantageous to do so. We cannot make any assurance that debt and equity financing will be available to us on favorable terms, or at all, and debt financings may be restricted by the terms of any of our outstanding borrowings. If additional funds are not available to us, we could be forced to curtail or cease new asset originations and acquisitions, which could have a material adverse effect on our business and financial condition. Risks related to our borrowings and hedging We use financial leverage in executing our business strategy, which may adversely affect the returns on our assets and may reduce cash available for distribution to our stockholders, as well as increase losses when economic conditions are unfavorable. We use debt to finance our assets, including credit facilities, recourse and non-recourse debt, securitizations, and syndications. Changes in the financial markets and the economy generally could adversely affect one or more of our lenders or potential lenders and could cause one or more of our lenders, potential lenders or institutional investors to be unwilling or unable to provide us with financing or participate in securitizations or could increase the costs of that financing or securitization. Some of our borrowings will have a remaining balance when they come due. If we are unable to repay or refinance the remaining balance of this debt, or if the terms of any available refinancing are not favorable, we may be forced to liquidate assets or incur higher costs which may significantly harm our business, financial condition, results of operations, and our ability to make distributions, which could cause the value of our common stock to decline. The return on our assets and cash available for distribution to our stockholders may be reduced to the extent that market conditions prevent us from leveraging our assets or increase the cost of our financing relative to the income that can be derived from the assets acquired. Increases in our financing costs will reduce cash available for distributions to stockholders. We may not be able to meet our financing obligations and, to the extent that we cannot, we risk the loss of some or all of our assets to liquidation or sale to satisfy the obligations. An increase in our borrowing costs relative to the interest we receive on our assets may adversely affect our profitability and our cash available for distribution to our stockholders. Our borrowings may have a shorter duration than our assets. As some of our borrowings will have a remaining balance at maturity, we may be required to enter into new borrowings at higher rates or to sell certain of our assets to repay the loan. In addition, any increases in the federal funds rate announced by the Federal Reserve Board of Governors is likely to increase shorter-term interest rates and may lower the difference between shorter-term interest rates and longer-term interest rates which would result in a flattening or inversion of the yield curve. The Federal Reserve Board of Governors raised the federal funds rate nine times during the period between December 2015 and December 2018 and has announced its intention to determine what future adjustments are appropriate to the federal funds rate over time, including as a result of increased concerns over inflation, but such changes in fiscal and monetary policies are beyond our control and are difficult to predict. Our credit facilities have rates that adjust on a frequent basis based on prevailing short-term interest rates. An increase in interest rates, or a flattening or inversion of the yield curve, would reduce the spread between the returns on our assets which are typically priced using longer-term interest rates and the cost of any new borrowings or borrowings where the interest rate adjusts to market rates or is based on shorter-term rates. This change in interest rates would adversely affect our earnings and, in turn, cash available for distribution to our stockholders. In addition, as we may use short-term borrowings including repurchase agreements and warehouse facilities that are generally short-term commitments of capital, lenders may respond to market conditions making it more difficult for us to obtain continued financing. If we are not able to renew our then existing facilities or arrange for new financing on terms acceptable to us, or if we default on our covenants or are otherwise unable to access funds under any of these facilities, we may have to curtail entering into new transactions and/or dispose of assets. We will face these risks given that a number of our borrowings have a shorter duration than the assets they finance. While we have an established Board-approved leverage limit, our Board may change our leverage limits without stockholder approval. We are not restricted by any regulatory requirements to maintain our leverage ratio at or below any particular level. The amount of leverage we may deploy for particular assets will depend upon the availability of particular types of financing and our assessment of the credit, liquidity, price volatility and other risks of those assets and the credit quality of our financing counterparties. We have established leverage limits which are discussed in Item 7, Management’s Discussion and Analysis of Financial Conditions and Results of Operations—Liquidity and Capital Resources. However, our charter and bylaws do not limit the amount or type of indebtedness we can incur, and our board of directors has changed, and has the discretion to deviate from or change at any time in the future, our leverage policy, which could result in an investment portfolio with a different risk profile. We utilize non-recourse facilities on certain types of assets that have significantly higher leverage. On these facilities, the lenders’ primary recourse is to the pledged assets. If the value of the pledged assets is below the value of the debt or if we default on a facility, the lender would be able to foreclose on all the pledged assets, which would result in losses and reduce our assets and the cash available for distributions to stockholders. We may apply too much leverage to our assets or may employ an inefficient financing strategy to our assets. The use of securitizations and special purpose entities exposes us to additional risks. We hold securitized loans and often hold the most junior certificates or the residual value associated with a securitization. We have also established funds and special purpose entities through which we hold only a partial or subordinate interest or a residual value after taking into account our non-recourse debt facilities or a right to participate in the profits of such entity once it achieves a predefined threshold. As a holder of the residual value or other such interests, we are more exposed to losses on the underlying collateral because the interest we | 2 5 HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS retain in the securitization vehicle or other entity would be subordinate to the more senior notes or interests issued to investors and we would, therefore, absorb all of the losses, up to the value of our interests, sustained with respect to the underlying assets before the owners of the notes or other interests experience any losses. In addition, the inability to securitize our Portfolio or assets within our Portfolio could hurt our performance and our ability to grow our business. We also use various special purpose entities to own and finance our assets. These subsidiaries incur various types of debt, that can be used to finance one or more of our assets. This debt is typically structured as non-recourse debt, which means it is repayable solely from the revenue from the investment financed by the debt and is secured by the related physical assets, major contracts, cash accounts and in some cases, a pledge of our ownership interests in the subsidiaries involved in the projects. Although this subsidiary debt is typically non-recourse to us, we make certain representations and warranties or enter into certain guaranties of our subsidiary’s obligations or covenants to the non-recourse debt holder, the breach of which may require us to make payments to the lender. We may also from time to time determine to provide financial support to the subsidiary in order to maintain rights to the project or otherwise avoid the adverse consequences of a default. In the event a subsidiary defaults on its indebtedness, its creditors may foreclose on the collateral securing the indebtedness, which may result in us losing our ownership interest in some or all of the subsidiary’s assets. The loss of our ownership interest in a subsidiary or some or all of a subsidiary’s assets could have a material adverse effect on our business, financial condition and operating results. Our existing credit facilities and debt contain, and any future financing facilities may contain, covenants that restrict our operations and may inhibit our ability to grow our business and increase revenues. Our existing credit facilities and debt contain, and any future financing facilities may contain, various affirmative and negative covenants, including maintenance of an interest coverage ratio and limitations on the incurrence of liens and indebtedness, investments, fundamental organizational changes, dispositions, changes in the nature of business, transactions with affiliates, use of proceeds and stock repurchases. In addition, the terms of our non-recourse debt include restrictions and covenants, including limitations on our ability to transfer or incur liens on the assets that secure the debt. For further information see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources. The covenants and restrictions included in our existing financings do, and the covenants and restrictions to be included in any future financings may, restrict our ability to, among other things: z incur or guarantee additional debt; z make certain investments, originations or acquisitions; z make distributions on or repurchase or redeem capital stock; z engage in mergers or consolidations; z reduce liquidity below certain levels; z grant liens; z have a tangible net worth below a defined threshold; z incur operating losses for more than a specified period; and z enter into transactions with affiliates. Our non-recourse debt limits our ability to take action with regard to the assets pledged as security for the debt. These restrictions, as well as any other covenants contained in any future financings, may interfere with our ability to obtain financing, or to engage in other business activities, which may significantly limit or harm our business, financial condition, liquidity and results of operations. Certain financing agreements also contain cross-default provisions, so that if a default occurs under any one agreement, the lenders under our other agreements could also declare a default. A default and resulting repayment acceleration could significantly reduce our liquidity, which could require us to sell our assets to repay amounts due and outstanding. This could also significantly harm our business, financial condition, results of operations, and our ability to make distributions, which could cause the value of our common stock to decline and adversely affect our ability to qualify, or remain qualified, as a REIT. A default will also significantly limit our financing alternatives such that we will be unable to pursue our leverage strategy, which could curtail the returns on our assets. In addition, certain of our financing arrangements contain provisions that provide for a preference in cash flow allocations to the lender from our assets or an acceleration of principal payments owed when certain conditions are present related to the underlying assets that serve as collateral for the financing. These provisions may limit our ability to obtain distributions from the underlying assets and could impact our cash flow and expected returns. We have issued senior unsecured notes which require us to maintain a certain amount of unencumbered assets as a part of our Portfolio, as well as to maintain certain debt coverage service ratios in order to issue additional notes. These provisions may limit our ability to leverage certain assets and limit our overall debt levels. We will have to pay off the remaining balance or refinance our borrowings when they become due. The failure to be able to pay off the remaining balance or refinance such borrowings or an increase in interest rates of such refinancing could have a material impact on our business. Some of our borrowings will have a remaining balance when they become due. If our subsidiary is unable to repay or refinance the remaining balance of this debt, or if the terms of any available refinancing are not favorable, we may be forced to liquidate assets or incur higher costs which may significantly harm our business, financial condition, results of operations, and our ability to make distributions, which could cause the value of our common stock to decline. If a counterparty to repurchase transactions defaults on its obligation to resell the underlying security back to us at the end of the transaction term, or if the value of the underlying security has declined as of the end of that term, or if we default on obligations under the repurchase agreement, we may lose money on repurchase transactions. In repurchase transactions, we will generally sell certain of our assets to lenders (i.e., repurchase agreement counterparties) and receive cash from the lenders. The lenders will be obligated to resell the same assets back to us at the end of the term of the transaction. Because the cash we will receive from the lender when we initially sell the assets to the lender is less than its value, if the lender defaults on its obligation to resell the same asset back to us we would incur a loss 2 6 | HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS on the transaction equal to the differential in value at which the lender purchased the asset (assuming there was no other change in value). We would also lose money on a repurchase transaction if the value of the underlying asset has declined as of the end of the transaction term, as we would have to repurchase the assets for their initial value but would receive loans worth less than that amount. We may also be forced to sell assets at significantly depressed prices to meet margin calls, post additional collateral and maintain adequate liquidity, which could cause us to incur losses. Moreover, to the extent we are forced to sell assets at such time, given market conditions, we may be selling at the same time as others facing similar pressures, which could exacerbate a difficult market environment and which could result in our incurring significantly greater losses on our sale of such assets. In an extreme case of market duress, a market may not even be present for certain of our assets at any price. Such a situation would likely result in a rapid deterioration of our financial condition and possibly necessitate a filing for protection under the United States Bankruptcy Code (the “Bankruptcy Code”). Further, if we default on one of our obligations under a repurchase transaction, the lender will be able to terminate the transaction and cease entering into any other repurchase transactions with us. Our repurchase agreements may contain cross- default provisions, so that if a default occurs under any one agreement, the lenders under any other of our agreements could also declare a default. If a default occurs under any of our repurchase agreements and the lenders terminate one or more of our repurchase agreements, we may need to enter into replacement repurchase agreements with different lenders. There can be no assurance that we will be successful in entering into such replacement repurchase agreements on the same terms as the repurchase agreements that were terminated or at all. Any losses we incur on our repurchase transactions could adversely affect our earnings and thus our cash available for distribution to our stockholders. In the event of our insolvency or bankruptcy, certain repurchase agreements may qualify for special treatment under the Bankruptcy Code, the effect of which, among other things, would be to allow the lender under the applicable repurchase agreement to avoid the automatic stay provisions of the Bankruptcy Code and to foreclose on the collateral agreement without delay, which could ultimately reduce the amounts we could otherwise recover. The discontinuation of U.S. dollar London Interbank Offered Rate (“LIBOR”) may adversely affect our borrowing costs and the costs of any related hedging transactions. The terms of certain of our revolving credit facilities and interest rate hedge agreements refer to U.S. dollar LIBOR. As announced on March 5, 2021 by the ICE Benchmark Administration Limited (“IBA”) and the U.K. Financial Conduct Authority, the IBA will cease publishing the overnight, 1-month, 3-month, 6-month and 12-month settings of U.S. dollar LIBOR rates immediately after June 30, 2023. The Alternative Reference Rates Committee (“ARCC”), which was convened by the Federal Reserve Board and the New York Federal Reserve Bank, has identified the Secured Overnight Financing Rate (“SOFR”) as the recommended risk-free alternative rate for U.S. dollar LIBOR. Some of our financing arrangements may not include robust fallback language that would facilitate replacing U.S. dollar LIBOR with a clearly defined alternative reference rate. We may not able to amend or refinance these credit facilities and interest rate hedge agreements prior to the discontinuation of U.S. dollar LIBOR, or applicable legislation or regulations may provide a benchmark replacement rate based on SOFR, a spread adjustment and conforming changes. Even when robust fallback language is included in financing arrangements, there can be no assurance that the benchmark replacement rate plus any spread adjustment will be economically equivalent to U.S. dollar LIBOR. In addition, market practices related to calculation conventions for replacement benchmark rates continue to develop and may vary, and inconsistent conventions may develop among financial products. Inconsistent use of replacement rates or calculation conventions among financial products could expose us to additional financial risks and increase the cost of any related hedging transactions. It is not possible to predict all consequences of the IBA’s plans to cease publishing LIBOR, any related regulatory actions and the expected discontinuance of the use of LIBOR as a reference rate for financial contracts. Any transition from LIBOR to alternative reference rates could result in financial market disruptions or significant increases in our borrowing costs or the costs of any related hedging, any of which could have an adverse effect on our business, results of operations, financial condition, and the market price of our common stock. Borrowings under our CarbonCount®-Based Revolving Credit Facility bear interest at a variable rate that is based on the SOFR, which may have consequences for us that cannot be reasonably predicted and may adversely affect our liquidity, financial condition, and results of operations. Borrowings under our CarbonCount®-Based Revolving Credit Facility may bear interest at a rate per annum that is based upon SOFR. Although SOFR has been endorsed by the Alternative Reference Rates Committee as its preferred replacement for LIBOR, it remains uncertain whether or when SOFR or other alternative reference rates will be widely accepted by lenders as the replacement for LIBOR. This may, in turn, impact the liquidity of the SOFR loan market, and SOFR itself. Since the initial publication of SOFR, daily changes in the rate have, on occasion, been more volatile than daily changes in comparable benchmark or market rates, and SOFR over time may bear little or no relation to the historical actual or historical indicative data and use of SOFR may result in interest rates and/or payments that are higher or lower than the rates and payments that we might have experienced using LIBOR. Also, the use of SOFR based rates is relatively new, and there could be unanticipated difficulties or disruptions with the calculation and publication of SOFR based rates. In particular, if the agent under the CarbonCount®-Based Revolving Credit Facility determines that SOFR based rates cannot be determined or the agent or the lenders determine that SOFR based rates do not adequately reflect the cost of funding the SOFR loans, outstanding SOFR loans will be converted into ABR Loans (as defined in the CarbonCount®-Based Revolving Credit Facility). The possible volatility of and uncertainty around SOFR as a LIBOR replacement rate and the potential conversion to ABR Loans could result in higher borrowing costs for us, which would adversely affect our liquidity, financial condition, and results of operations. We, or the projects in which we invest, enter into hedging transactions that could expose us to contingent liabilities or additional credit risk in the future and adversely impact our financial condition. Subject to maintaining our qualification as a REIT, part of our strategy, or the strategy of the projects in which we invest, involves entering into hedging transactions that could require us to fund cash payments in certain circumstances (e.g., the early termination of the hedging | 2 7 HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS instrument caused by an event of default or other early termination event, or the decision by a counterparty to request margin it is contractually owed under the terms of the hedging instrument). The amount due would be equal to the unrealized loss of the open swap positions with the respective counterparty and could also include other fees and charges. These economic losses will be reflected in our, or the project’s, financial statements, and our, or the project’s, ability to fund these obligations will depend on the liquidity of our, or the project’s, assets and access to capital at the time, and the need to fund these obligations could adversely impact our financial condition. In addition, over-the-counter hedges entered into to hedge interest rates, credit risk or commodity prices involve risk since they often are not traded on regulated exchanges or cleared through a central counterparty. We would remain exposed to our counterparty’s ability to perform on its obligations under each hedge and cannot look to the creditworthiness of a central counterparty for performance. As a result, if a hedging counterparty cannot perform under the terms of the hedge, we would not receive payments due under that hedge, we may lose any unrealized gain associated with the hedge and the hedged liability would cease to be hedged. While we would seek to terminate the relevant hedge transaction and may have a claim against the defaulting counterparty for any losses, including unrealized gains, there is no assurance that we would be able to recover such amounts or to replace the relevant hedge on economically viable terms or at all. In such case, we could be forced to cover our unhedged liabilities at the then current market price. We may also be at risk for any collateral we have pledged to secure our obligations under the hedge if the counterparty becomes insolvent or files for bankruptcy. Furthermore, our interest rate swaps and other hedge transactions are subject to increasing statutory and other regulatory requirements and, depending on the identity of the counterparty, applicable international requirements. Recently, new regulations have been promulgated by U.S. and foreign regulators to strengthen the oversight of swaps, and any further actions taken by such regulators could constrain our strategy or increase our costs, either of which could materially and adversely impact our results of operations. Additionally, applicable regulations require certain derivatives, including certain interest rate swaps, to be executed on a regulated market and cleared through a central counterparty. Unlike over-the- counter swaps, the counterparty for the cleared swaps is the clearing house, which reduces counterparty risk. However, cleared swaps require us to appoint clearing brokers and to post margin in accordance with the clearing house’s rules, which has resulted in increased costs Risks related to our common stock for cleared swaps compared to over-the-counter swaps. Our over-the- counter hedges with swap dealers are subject to margin regulations which prescribe the required margin, limit eligible margin to cash and specified types of securities. These margin regulations have the effect, therefore, of increasing the costs of hedging and could induce us to limit our use of certain hedging transactions. Also, any mortgage real estate investment trust that trades in swaps may be considered a “commodity pool,” which would cause its operator to be regulated as a “commodity pool operator” (a “CPO”). Operators of mortgage REITs are currently exempt from CPO registration requirements, subject to certain qualification parameters. The need to operate within these parameters could limit the use of swaps and other commodity interests by us below the level that we would otherwise consider optimal or may lead to the registration of our company, our management team or our directors as commodity pool operators, which will subject us to additional regulatory oversight, compliance and costs. Moreover, the projects in which we invest, may enter into various forms of hedging including interest rate and power price hedging. To the extent they enter into such hedges, the financial results of the project will be exposed to similar risks as described above which could adversely impact our results of operations. If we, or our projects, choose not to pursue, or fail to qualify for, hedge accounting treatment, our operating results may be impacted because losses on the derivatives that we enter into may not be offset by a change in the fair value of the related hedged transaction. We, or our projects, may choose not to pursue, or fail to qualify for, hedge accounting treatment relating to derivative and hedging transactions. We, or our projects, may fail to qualify for hedge accounting treatment for a number of reasons, including if we, or our projects, use instruments that do not meet the Accounting Standards Codification (“ASC”) Topic 815 definition of a derivative, we, or our projects, fail to satisfy ASC Topic 815 hedge documentation and hedge effectiveness assessment requirements or the hedge relationship is not highly effective. If we, or our projects, fail to qualify for, or choose not to pursue, hedge accounting treatment, our, or our projects, operating results may be impacted because losses on the derivatives that we, or our projects, enter into may not be offset by a change in the fair value of the related hedged transaction. An active trading market for our common stock may not continue, which could cause our common stock to trade at a discount and make it difficult for holders of our common stock to sell their shares. Our common stock is listed on the New York Stock Exchange (“NYSE”). However, an active trading market for our common stock may not continue, which could cause our common stock to trade at a discount to historical prices. Some of the factors that have or in the future could negatively affect the market price of our common stock include: z our actual or projected operating results, financial condition, cash flows and liquidity or changes in business strategy or prospects; z changes in the mix of our investment products and services, including the level of securitizations or fee income in any quarter; z actual or perceived conflicts of interest with individuals, including our executives; z our ability to arrange financing for projects; z equity issuances by us, or share resales by our stockholders, or the perception that such issuances or resales may occur; z seasonality in construction and demand for our investments; z actual or anticipated accounting problems; z publication of research reports about us or the climate solutions industry; 2 8 | HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS z changes in market valuations of similar companies; z adverse market reaction to any increased indebtedness we may incur in the future; z commodity price changes; z interest rate changes; z additions to or departures of our key personnel; z speculation or negative publicity in the press or investment community; z our failure to meet, or the lowering of, our earnings estimates or those of any securities analysts; z increases in market interest rates, which may lead investors to demand a higher distribution yield for our common stock, and would result in increased interest expenses on certain of our debt; z changes in governmental policies, regulations or laws; z failure to qualify, or maintain our qualification, as a REIT or failure to maintain our exemption from registration as an investment company under the 1940 Act; z price and volume fluctuations in the stock market generally; and z general market and economic conditions, including the current state of the credit and capital markets. Market factors unrelated to our performance also have, and could in the future, negatively impact the market price of our common stock. One of the factors that investors may consider in deciding whether to buy or sell our common stock is our distribution rate as a percentage of our stock price relative to market interest rates. If market interest rates increase, prospective investors may demand a higher distribution rate or seek alternative investments paying higher dividends or interest. As a result, interest rate fluctuations and conditions in capital markets have, or in the future could, affect the market value of our common stock. Common stock and preferred stock eligible for future sale may have adverse effects on our share price. Subject to applicable law, our Board, without stockholder approval, may authorize us to issue additional authorized and unissued shares of common stock and preferred stock on the terms and for the consideration it deems appropriate. We cannot predict the effect, if any, of future sales of our common stock or the availability of shares for future sales, on the market price of our common stock. Sales of substantial amounts of common stock or the perception that such sales could occur may adversely affect the prevailing market price for our common stock. We cannot assure you of our ability to make distributions in the future. If our portfolio of assets fails to generate sufficient income and cash flow, we could be required to sell assets, borrow funds, raise additional equity or make a portion of our distributions in the form of a taxable stock distribution or distribution of debt securities. We are generally required to distribute to our stockholders at least 90% of our REIT taxable income (without regard to the deduction for dividends paid and excluding net capital gains) each year for us to qualify, and maintain our qualification, as a REIT under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). Our current policy is to pay quarterly distributions, which on an annual basis is expected to equal or substantially exceed 90% or more of our REIT taxable income. In the event that our Board authorizes distributions in excess of the income or cash flow generated from our assets, we may make such distributions from the proceeds of future offerings of equity or debt securities or other forms of debt financing or the sale of assets. Our ability to make distributions may be adversely affected by a number of factors. Therefore, although we anticipate making quarterly distributions to our stockholders, our Board has the sole discretion to determine the timing, form and amount of any distributions to our stockholders. If our portfolio of assets fails to generate sufficient income and cash flow, we could be required to sell assets, borrow funds, raise additional equity or make a portion of our distributions in the form of a taxable stock distribution or distribution of debt securities. To the extent that we are required to sell assets in adverse market conditions or borrow funds at unfavorable rates, our results of operations could be materially and adversely affected. If we raise additional equity, our stock price could be materially and adversely affected. Our Board will make determinations regarding distributions based upon various factors, including our earnings, our financial condition, our liquidity, our debt covenants, maintenance of our REIT qualification, applicable provisions of the MGCL and other factors as our Board may deem relevant from time to time. We believe that a change in any one of the following factors could adversely affect our results of operations and impair our ability to make distributions to our stockholders: z our ability to make profitable investments; z margin calls or other expenses that reduce our cash flow; z defaults in our asset portfolio or decreases in the value of our portfolio; z the cash flow we receive from our assets, including those subject to non-recourse debt; and z the fact that anticipated operating expense levels may not prove accurate, as actual results may vary from estimates. As a result, no assurance can be given that we will be able to make distributions to our stockholders at any time in the future or that the level of any distributions we do make to our stockholders will achieve a market yield or increase or even be maintained over time, any of which could materially and adversely affect us. In addition, all or a portion of the distributions that we make to our stockholders will be taxable as ordinary income, subject to a potential deduction equal to 20% of the amount of such dividends for taxable years beginning in 2018 and ending in 2025, which generally reduces the effective U.S. federal income tax rate applicable to such dividends. However, a portion of our distributions may be designated by us as long-term capital gains to the extent that they are attributable to capital gain income recognized by us or may constitute a return of capital to the extent that they exceed our earnings and profits as determined for tax purposes. A return of capital is not taxable income but has the effect of reducing the basis of a stockholder’s investment in shares of our common stock. Future offerings of debt or equity securities, which may rank senior to our common stock, may adversely affect the market price of our common stock. Our present debt ranks, and any future debt would rank, senior to our common stock. Such debt is, and likely will be, governed by a loan agreement, an indenture, or other instrument containing covenants restricting our operating flexibility. Additionally, our convertible | 2 9 HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS securities, and any equity securities or convertible or exchangeable securities that we issue in the future may have rights, preferences and privileges more favorable than those of our common stock and may result in dilution to owners of our common stock. We and, indirectly, our stockholders will bear the cost of issuing and servicing such debt or securities. Because our decision to issue debt or equity securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing, or nature of our future offerings. Thus, holders of our common stock will bear the risk of our future offerings reducing the market price of our common stock and diluting the value of their stock holdings in us. Risks related to our organization and structure Our business could be harmed if key personnel terminate their employment with us. Our success depends, to a significant extent, on the continued services of our senior management team. We have entered into employment agreements with certain members of our senior management team. Notwithstanding these agreements, there can be no assurance that any or all members of our senior management team will remain employed by us. We do not maintain key person life insurance on any of our officers other than two policies we maintain for Mr. Eckel under which we are a beneficiary in the amount of approximately $500 thousand. The loss of services of one or more members of our senior management team could harm our business and our prospects. Conflicts of interest could arise as a result of our structure. Conflicts of interest could arise in the future as a result of the relationships between us and our affiliates, on the one hand, and our Operating Partnership or any partner thereof, on the other. Our directors and officers have duties to our company under applicable Maryland law in connection with our management. Our duties, as the general partner, to our Operating Partnership and our partners may come into conflict with the duties of our directors and officers to us. Under Delaware law, a general partner of a Delaware limited partnership owes its limited partners the duties of good faith and fair dealing. Other duties, including fiduciary duties, may be modified or eliminated in the partnership’s partnership agreement, except that conflict of interest transactions may still run afoul of implied contractual standards under Delaware law. The partnership agreement of our Operating Partnership provides that, for so long as we own a controlling interest in our Operating Partnership, any conflict that cannot be resolved in a manner not adverse to either our stockholders or the limited partners will be resolved in favor of our stockholders. We have not obtained an opinion of counsel covering the provisions set forth in the partnership agreement of our Operating Partnership that purport to waive or restrict our fiduciary duties that would be in effect under common law were it not for the partnership agreement of our Operating Partnership. Additionally, the partnership agreement of our Operating Partnership expressly limits our liability by providing that neither we, as the general partner of the Operating Partnership, nor any of our directors or officers, will be liable or accountable in damages to our Operating Partnership, its limited partners or their assignees for errors in judgment, mistakes of fact or law or for any act or omission if the general partner, director or officer, acted in good faith. In addition, our Operating Partnership is required to indemnify us, our affiliates and each of our and their respective officers, directors, employees and agents to the fullest extent permitted by applicable law against any and all losses, claims, damages, liabilities (whether joint or several), expenses (including, without limitation, attorneys’ fees and other legal fees and expenses), judgments, fines, settlements and other amounts arising 3 0 | from any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative, that relate to the operations of the Operating Partnership, provided that our Operating Partnership will not indemnify any such person for (1) willful misconduct or a knowing violation of the law, (2) any transaction for which such person received an improper personal benefit in violation or breach of any provision of the partnership agreement of our Operating Partnership, or (3) in the case of a criminal proceeding, the person had reasonable cause to believe the act or omission was unlawful. Certain provisions of Maryland law could inhibit changes in control. Certain provisions of the MGCL may have the effect of deterring a third party from making a proposal to acquire us or of impeding a change in control under circumstances that otherwise could provide the holders of our common stock with the opportunity to realize a premium over the then-prevailing market price of our common stock. We are subject to the “business combination” provisions of the MGCL that, subject to limitations, prohibit certain business combinations between us and an “interested stockholder” (defined generally as any person who beneficially owns 10% or more of our then outstanding voting stock or an affiliate or associate of ours who, at any time within the two-year period prior to the date in question, was the beneficial owner of 10% or more of our then outstanding voting stock) or an affiliate thereof for five years after the most recent date on which the stockholder becomes an interested stockholder and, thereafter, impose fair price and/or supermajority stockholder voting requirements on these combinations. The “control share” provisions of the MGCL provide that, subject to certain exemptions, a holder of “control shares” of a Maryland corporation (defined as shares which, when aggregated with all other shares controlled by the stockholder (except solely by virtue of a revocable proxy), entitle the stockholder to exercise one of three increasing ranges of voting power in electing directors) acquired in a “control share acquisition” (defined as the direct or indirect acquisition of ownership or control of issued and outstanding “control shares”) has no voting rights with respect to such shares except to the extent approved by our stockholders by the affirmative vote of at least two thirds of all the votes entitled to be cast on the matter, excluding votes entitled to be cast by the acquirer of control shares, our officers and our directors who are also our employees. The “unsolicited takeover” provisions of Title 3, Subtitle 8 of the MGCL permit our Board, without stockholder approval and regardless of what is currently provided in our charter or bylaws, to implement certain takeover defenses, some of which (for example, a classified board) we do not yet have. As permitted by the MGCL, our Board has by resolution exempted from the “business combination” provision of the MGC business combinations (1) between us and any other person, provided, that such business combination is first approved by our Board (including HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS a majority of our directors who are not affiliates or associates of such person), (2) the Predecessor and its affiliates and associates as part of our formation transactions and (3) persons acting in concert with any of the foregoing. Our bylaws contain a provision exempting from the control share acquisition statute any and all acquisitions by any person of shares of our stock. There can be no assurance that our Board will not amend or revoke the exemption at any time. Our authorized but unissued shares of common and preferred stock may prevent a change in our control. Our charter permits our Board to authorize us to issue additional shares of our authorized but unissued common or preferred stock. In addition, our Board may, without common stockholder approval, amend our charter to increase the aggregate number of our shares of stock or the number of shares of stock of any class or series that we have the authority to issue and classify or reclassify any unissued shares of common or preferred stock and set the terms of the classified or reclassified shares. As a result, our Board may establish a series of common or preferred stock that could delay or prevent a transaction or a change in control that might involve a premium price for shares of our common stock or otherwise be in the best interest of our stockholders. Our rights and the rights of our stockholders to take action against our directors and officers are limited, which could limit stockholder recourse in the event of actions not in our stockholders’ best interests. Our charter eliminates the liability of our present and former directors and officers to us and our stockholders for money damages to the maximum extent permitted under Maryland law. Our charter authorizes us, and our bylaws and indemnification agreements entered into with each of our directors and executive officers require us, to the maximum extent permitted by Maryland law, to indemnify and, without requiring a preliminary determination of their ultimate entitlement to indemnification, to pay or reimburse defense costs and other expenses of each of our directors and officers in the defense of any proceeding to which he or she is made, or threatened to be made, a party or witness by reason of his or her service to us. Risks related to our taxation as a REIT Qualifying as a REIT involves highly technical and complex provisions of the Internal Revenue Code, and our failure to qualify or remain qualified as a REIT would subject us to U.S. federal income tax and applicable state and local tax, which would negatively impact the results of our operations and reduce the amount of cash available for distribution to our stockholders. We have elected to be treated, and qualify, as a REIT for U.S. federal income tax purposes. The U.S. federal income tax laws governing REITs are complex, and judicial and administrative interpretations of the U.S. federal income tax laws governing REIT qualification are limited. To qualify as a REIT and remain so qualified, we must meet, on an ongoing basis through actual operating results, various tests regarding the nature and diversification of our assets and our income, the ownership of our outstanding shares, and the amount of our distributions. Even a technical or inadvertent violation could jeopardize our REIT qualification. Our ability to satisfy the asset tests depends Our charter contains provisions that make removal of our directors difficult, which could make it difficult for our stockholders to effect changes to our management. Our charter provides that, subject to the rights of holders of any series of preferred stock, a director may be removed with or without cause upon the affirmative vote of holders of at least two thirds of the votes entitled to be cast generally in the election of directors. Vacancies may be filled only by a majority of the remaining directors in office, even if less than a quorum. These requirements make it more difficult to change our management by removing and replacing directors and may prevent a change in control of our company that is in the best interests of our stockholders. Ownership limitations may restrict change of control or business combination opportunities in which our stockholders might receive a premium for their shares. In order for us to qualify as a REIT for each taxable year after 2013, no more than 50% in value of our outstanding capital stock may be owned, directly or constructively, by five or fewer individuals during the last half of any calendar year, and at least 100 persons must beneficially own our stock during at least 335 days of a taxable year of 12 months, or during a proportionate portion of a shorter taxable year. “Individuals” for this purpose include natural persons, private foundations, some employee benefit plans and trusts, and some charitable trusts. To assist us in preserving our REIT qualification, among other purposes, our charter generally prohibits any person from directly or indirectly owning more than 9.8% in value or in number of shares, whichever is more restrictive, of the aggregate outstanding shares of our capital stock, the outstanding shares of any class or series of our preferred stock or the outstanding shares of our common stock. These ownership limits could have the effect of discouraging a takeover or other transaction in which holders of our common stock might receive a premium for their shares over the then prevailing market price or which holders might believe to be otherwise in their best interests. Our Board has established exemptions from these ownership limits that permit certain institutional investors and their clients to hold shares of our common stock in excess of these ownership limits. upon our analysis of the characterization and fair market values of our assets, some of which are not susceptible to a precise determination, and for which we will not obtain independent appraisals. We received a private letter ruling from the Internal Revenue Service (“IRS”), which we refer to as the Ruling, relating to our ability to treat certain of our assets as qualifying REIT assets. We are entitled to rely on this Ruling for those assets which fit within the scope of the Ruling only to the extent that we have the legal and contractual rights described therein, we continue to operate in accordance with the relevant facts described in the ruling request we submitted, that such facts were accurately presented and to the extent such ruling is not inconsistent with the Real Property Regulations (as discussed in more detail below). As a result, no assurance can be given that we will always be able to rely on this Ruling. In August of 2016, the Treasury Department and the IRS published regulations which we refer to as the Real Property Regulations relating to the definition of “real property” for purposes of the REIT income | 3 1 HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS and asset tests with respect to our taxable years beginning after December 31, 2016. Among other things, the Real Property Regulations provide that an obligation secured by a structural component of a building or other inherently permanent structure qualifies as a real estate asset for REIT qualification purposes only if such obligation is also secured by a real property interest in the inherently permanent structure served by such structural component. This aspect of the Real Property Regulations has important implications for our qualification as a REIT since a significant portion of our REIT qualifying assets consists of receivables that are secured by liens on installed structural improvements designed to improve the energy efficiency of buildings and a significant portion of our REIT qualifying gross income is interest income earned with respect to such receivables. The structural improvements securing our receivables generally qualify as “fixtures” under local real property law, as well as under the Uniform Commercial Code, or the UCC, which governs rights and obligations of parties in secured transactions. Although not controlling for REIT purposes, the general rule in the United States is that once improvements are permanently installed in real properties, such improvements become fixtures and thus take on the character of and are considered to be real property for certain state and local law purposes. In general, in the United States, laws governing fixtures, including the UCC and real property law, afford lenders who have secured their financings with security interests in fixtures with rights that extend not just to the fixtures that secure their financings, but also to the real properties in which such fixtures have been installed. By way of example only, Section 9-604(b) of the UCC, which has been adopted in all but two states in the United States, permits a lender secured by fixtures, upon a default, to enforce its rights under the UCC or under applicable real property laws. Although there is limited authority directly on point, given the nature of, and the extent to which, the structural improvements securing our receivables are integrated into and serve the related buildings, we believe that the better view is that the nature and scope of our rights in such buildings that inure to us as a result of our receivables are sufficient to satisfy the requirements of the Real Property Regulations described above. In addition to the limited authority directly on point, two other important caveats apply in this regard. First, the Real Property Regulations do not define what is required for an obligation secured by a lien on a structural component to also be secured by a real property interest in the building served by such structural component. However, the initial proposed version of the Real Property Regulations, which never became effective, included a requirement that the interest in the real property held by a REIT be “equivalent” to the interest in a structural component held by the REIT in order for the structural component to be treated as a real estate asset. This requirement was ultimately not included in the final Real Property Regulations, in part in response to comments that such requirement may negatively affect investment in energy efficiency and renewable energy assets. We believe the deletion of this requirement implies that under the final Real Property Regulations, our rights in the building need not be equivalent to our rights in the structural components serving the building. Second, real property law is typically relegated to the states and the specific rights available to any lien or mortgage holder, including our rights as a fixture lien holder described above, may vary between jurisdictions as a result of a range of factors, including the specific local real property law requirements and judicial and regulatory interpretations of such laws, and the competing rights of mortgage and other lenders. We have applied the analysis described above in a number of states that have adopted Section 9-604(b) of the UCC. In addition, in states where Section 9-604(b) of the UCC has not been adopted, we apply the analysis described above based on the application of the local real property laws of that state to the extent that we have received advice from counsel in those jurisdictions that local real property law provides us with appropriate rights to the buildings in which the structural improvements securing our receivables have been installed. Furthermore, we have applied the analysis described above to certain receivables secured by liens on structural improvements installed in buildings located in certain U.S. installations outside of the United States, based on our view that such installations are subject to U.S. sovereignty and as a result the UCC applies in such installations. While a number of cases have addressed the rights of fixture lien holders generally, there are limited judicial interpretations in only a few jurisdictions that directly address the rights and remedies available to a fixture lien holder in the real property in which the fixtures have been installed. Such rights have been addressed in some cases that support our position and, in factual circumstances distinguishable from our own, in some cases where the courts have found these rights to be more limited. The resolution of these issues in many jurisdictions therefore remains uncertain. As a result of the foregoing, no assurance can be given that the IRS will not challenge our position that our receivables meet the requirements of the Real Property Regulations or that, if challenged, such position would be sustained. The preamble to the Real Property Regulations provides that, to the extent a private letter ruling issued prior to the issuance of the Real Property Regulations is inconsistent with the Real Property Regulations, the private letter ruling is revoked prospectively from the applicability date of the Real Property Regulations. We do not believe that the Ruling is inconsistent with the Real Property Regulations because we believe the analysis in the Ruling was based on similar principles as the relevant portions of the Real Property Regulations, and accordingly we do not believe that the Real Property Regulations impact our ability to rely on the Ruling. However, no assurance can be given that the IRS would not successfully assert that we are not permitted to rely on the Ruling because the Ruling has been revoked by the Real Property Regulations. If the IRS were to assert that a significant portion of our receivables do not qualify as real estate assets and do not generate income treated as interest income from mortgages on real property, we would fail to satisfy both the gross income requirements and asset requirements applicable to REITs. If this were to occur, we would be required to restructure the manner in which we receive such income and we may realize significant income that does not qualify for the REIT 75% gross income test, which could cause us to fail to qualify as a REIT. In addition, our compliance with the REIT income and quarterly asset requirements also depends upon our ability to successfully manage the composition of our income and assets on an ongoing basis in accordance with existing REIT regulations and rules and interpretations thereof. Moreover, the IRS, new legislation, court decisions or other administrative guidance, in each case possibly with retroactive effect, may make it more difficult or impossible for us to qualify as a REIT. Our ability to satisfy the requirements to qualify as a REIT also depends in part on the actions of third parties over which we have no control or only limited influence, including in cases where we own an equity interest in an entity that is classified as a partnership for U.S. federal income tax purposes. Thus, given the highly complex nature of the rules governing REITs, the ongoing importance of factual determinations, and the possibility of future changes in our circumstances, no assurance 3 2 | HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS can be given that we will so qualify for any particular year. Further, differences in timing between the recognition of taxable income, our GAAP income and the actual receipt of cash may occur. For example, we may be required to accrue interest and discount income on debt securities or interests in debt securities before we receive any payments of interest or principal on such assets, and there may be timing differences in the accrual of such interest and discount income for tax purposes and for GAAP purposes. If we fail to qualify as a REIT in any taxable year, and we do not qualify for certain statutory relief provisions, we would be required to pay U.S. federal income tax on our net taxable income, and distributions to our stockholders would not be deductible by us in determining our taxable income. In such a case, we might need to borrow money or sell assets in order to pay our taxes. Our payment of income tax would negatively impact the results of our operations and decrease the amount of our income available for distribution to our stockholders. Furthermore, if we fail to maintain our qualification as a REIT, we no longer would be required to distribute substantially all of our taxable income to our stockholders, which would leave our Board with more discretion over our future distribution levels. In addition, unless we were eligible for certain statutory relief provisions, we could not re-elect to qualify as a REIT for the subsequent four taxable years following the year in which we failed to qualify. Complying with REIT requirements may force us to liquidate or forego otherwise attractive investments, incur debt, or sell assets at inopportune times. To qualify as a REIT, we must ensure that we meet the REIT gross income tests annually and that, at the end of each calendar quarter, at least 75% of the value of our total assets consists of cash, cash items, government securities, shares in REITs and other qualifying real estate assets. In addition, certain other limitations apply to the asset we may hold, which generally limit the concentration we may hold in assets that are not qualifying real estate assets. If we fail to comply with these requirements at the end of any calendar quarter, we must correct the failure within 30 days after the end of the calendar quarter or qualify for certain statutory relief provisions to avoid losing our REIT qualification and suffering adverse tax consequences. In addition, in order to qualify as a REIT, we must distribute to our stockholders, each calendar year, at least 90% of our REIT taxable income (including certain items of non-cash income), determined without regard to the deduction for dividends paid and excluding net capital gain. To the extent that we satisfy the 90% distribution requirement, but distribute less than 100% of our REIT taxable income, we will be subject to U.S. federal corporate income tax on our undistributed income. In addition, we will incur a 4% non-deductible excise tax on the amount, if any, by which our distributions in any calendar year are less than a minimum amount specified under U.S. federal income tax laws. We intend to distribute our taxable income to our stockholders in a manner intended to satisfy the REIT 90% distribution requirement and to avoid the 4% non-deductible excise tax. These requirements may require us to liquidate from our portfolio, or contribute to a taxable REIT subsidiary (a “TRS”), otherwise attractive investments, and we may be unable to pursue investments that would be otherwise advantageous to us in order to satisfy the source of income or asset diversification requirements for qualifying as a REIT. These actions could have the effect of reducing our income and amounts available for distribution to our stockholders. In addition, if we are compelled to liquidate our assets, such as to repay obligations to our lenders, this could impact our qualification with the REIT requirements, and we may be required to take actions to satisfy the REIT income, asset, or distribution tests, or else fail to qualify as a REIT. No assurance can be provided that we will satisfy these requirements under all circumstances. Furthermore, in order to meet the REIT distribution requirements, we may be required to: (i) sell assets in adverse market conditions, (ii) raise debt or equity on unfavorable terms, (iii) distribute amounts that would otherwise be invested in future acquisitions, capital expenditures or repayment of debt, (iv) make a taxable distribution of our shares as part of a distribution in which stockholders may elect to receive shares or (subject to a limit measured as a percentage of the total distribution) cash or (v) use cash reserves, in order to comply with the REIT distribution requirements and to avoid U.S. federal corporate income tax and the 4% non-deductible excise tax. Thus, compliance with the REIT distribution requirements may hinder our ability to grow, which could adversely affect the value of our common stock. Even though we qualify as a REIT, we may face tax liabilities that reduce our cash flow. Even though we qualify for taxation as a REIT, we may be subject to certain U.S. federal, state and local taxes on our income and assets, including taxes on any undistributed income, tax on income from some activities conducted as a result of a foreclosure, and state or local income, franchise, property and transfer taxes, including mortgage recording taxes. In addition, any TRSs we own will be subject to U.S. federal, state and local corporate income or franchise taxes. In order to meet the REIT qualification requirements, or to avoid the imposition of a 100% tax that applies to certain gains derived by a REIT from sales of inventory or property held primarily for sale to customers in the ordinary course of business, we may hold some of our assets through TRSs. Any taxes paid by such TRSs would decrease the cash available for distribution to our stockholders. The failure of assets subject to a repurchase agreement to be considered owned by us or mezzanine loans or other assets to qualify as real estate assets may adversely affect our ability to qualify as a REIT. We may enter into repurchase agreements under which we will nominally sell certain of our assets to a counterparty and simultaneously enter into an agreement to repurchase the sold assets. We believe that we will be treated for U.S. federal income tax purposes as the owner of the assets that are the subject of any such agreements and that the repurchase agreements will be treated as secured lending transactions notwithstanding that such agreements may transfer record ownership of the assets to the counterparty during the term of the agreement. It is possible, however, that the IRS could assert that we did not own the assets during the term of the repurchase agreement, in which case our REIT asset test could be adversely affected. In addition, we may acquire mezzanine loans, which are loans secured by equity interests in a partnership or limited liability company that directly or indirectly owns real property. In IRS Revenue Procedure 2003-65, the IRS provided a safe harbor pursuant to which a mezzanine loan, if it meets each of the requirements contained in the Revenue Procedure, will be treated by the IRS as a real estate asset for purposes of the REIT asset tests, and interest derived from the mezzanine loan will be treated as qualifying mortgage interest for purposes of the REIT 75% gross income test. Although IRS Revenue | 3 3 HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS Procedure 2003-65 provides a safe harbor on which taxpayers may rely, it does not prescribe rules of substantive tax law. We may acquire mezzanine loans that may not meet all of the requirements for reliance on this safe harbor. In the event we own a mezzanine loan that does not meet the safe harbor, the IRS could challenge such loan’s treatment as a real estate asset for purposes of the REIT asset and income tests, and if such a challenge were sustained, we could fail to qualify as a REIT. Further, we invest in assets such as C-PACE bonds and assessments, that we believe are secured by real property for purposes of the REIT income and asset tests but with respect to which no authority is directly on point. If the IRS were to successfully assert that such C-PACE assets are not qualifying assets for purposes of the REIT gross asset tests or do not generate qualifying income for purposes of the 75% gross income test, our REIT qualification could be adversely affected. Further, under certain circumstances, interest from debt instruments that are secured by real property and other property is required to be apportioned between qualifying real estate interest and nonqualifying interest based on the principal amount of the debt instrument and the fair market value of the underlying real property. If debt instruments that we hold were to generate a greater amount of nonqualifying interest than we anticipate, we could fail to satisfy the REIT gross income test, and could lose our REIT qualification or be required to pay a penalty tax to preserve our REIT compliance. We may be required to report taxable income for certain investments in excess of the economic income we ultimately realize from them. To the extent we acquire debt investments in the secondary market for less than their face amount, the amount of such discount will generally be treated as “market discount” for U.S. federal income tax purposes. Market discount is generally accrued on the basis of a constant yield to maturity of a debt investment. Accrued market discount is reported as income when, and to the extent that, any payment of principal of the debt instrument is made, unless we elect to include accrued market discount in income as it accrues. Principal payments on certain loans are made monthly, and consequently accrued market discount may have to be included in income each month as if the debt investment was assured of ultimately being collected in full. If we collect less on the debt investment than our purchase price plus the market discount we had previously reported as income, we may not be able to benefit from any offsetting loss deductions. Similarly, some of the debt investments that we acquire may have been issued with an original issue discount. We will generally be required to report such original issue discount based on a constant yield method and will be taxed based on the assumption that all future projected payments due on such debt investments will be made. If such debt investments turn out not to be fully collectible, an offsetting loss deduction will become available only in the later year that uncollectability is provable. In addition, in the event that any debt investments acquired by us are delinquent as to mandatory principal and interest payments, or in the event payments with respect to a particular debt investment are not made when due, we may nonetheless be required to continue to recognize the unpaid interest as taxable income as it accrues, despite doubt as to its ultimate collectability. While we would in general ultimately have an offsetting loss deduction available to us when such interest was determined to be uncollectible, the utility of that deduction could depend on our having taxable income in that later year or thereafter. Although we do not presently intend to, we may, in the future, acquire debt investments that are subsequently modified by agreement with the borrower. If such amendments are “significant modifications” under the applicable Treasury Regulations, we may be required to recognize taxable income as a result of such amendments. In addition, we may be required to accelerate our accrual for U.S. federal income tax purposes of certain items of income to the extent that we would otherwise recognize such items of income for U.S. federal income tax purposes later than we would report such items on our financial statements. Finally, we may be required under the terms of indebtedness that we incur with private lenders to use cash received from interest payments to make principal payments on that indebtedness, with the effect of recognizing income but not having a corresponding amount of cash available for distribution to our stockholders. These circumstances could affect our ability to satisfy the REIT distribution requirements. The “taxable mortgage pool” rules may increase the taxes that we or our stockholders may incur and may limit the way we effect future securitizations. Securitizations by us or our subsidiaries could result in the creation of taxable mortgage pools for U.S. federal income tax purposes. As a result, we could have “excess inclusion income.” Certain categories of stockholders, such as non-U.S. stockholders eligible for treaty or other benefits, U.S. stockholders with net operating losses, and certain U.S. tax-exempt stockholders that are subject to unrelated business income tax, could be subject to increased taxes on a portion of their dividend income from us that is attributable to any such excess inclusion income. In the case of a stockholder that is a REIT, a regulated investment company (a “RIC”), common trust fund or other pass-through entity, our allocable share of our excess inclusion income could be considered excess inclusion income of such entity. In addition, to the extent that our common stock is owned by U.S. tax-exempt “disqualified organizations,” such as certain government-related entities and charitable remainder trusts that are not subject to tax on unrelated business income, we may incur a corporate level tax on a portion of any excess inclusion income. Because this tax generally would be imposed on us, all of our stockholders, including stockholders that are not disqualified organizations, generally will bear a portion of the tax cost associated with the classification of us or a portion of our assets as a taxable mortgage pool. A RIC, or other pass-through entity owning our common stock in record name will be subject to tax at the highest U.S. federal corporate income tax rate on any excess inclusion income allocated to their owners that are disqualified organizations. Moreover, we could face limitations in selling equity interests in these securitizations to outside investors, or selling any debt securities issued in connection with these securitizations that might be considered to be equity interests for tax purposes. Finally, if we were to fail to qualify as a REIT, any taxable mortgage pool securitizations would be treated as separate taxable corporations for U.S. federal income tax purposes that could not be included in any consolidated U.S. federal corporate income tax return. These limitations may prevent us from using certain techniques to maximize our returns from securitization transactions. Our ownership of and relationship with our TRSs is limited and a failure to comply with the limits would jeopardize our REIT qualification and may result in the application of a 100% excise tax. Overall, no more than 20% of the value of a REIT’s total assets may consist of stock or securities of one or more TRSs. In order to satisfy 3 4 | HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS the TRS limitation, we may make loans to our TRSs that meet the requirements to be treated as qualifying investments of new capital, which are generally treated as real estate assets under the Internal Revenue Code. Because such loans are treated as real estate assets for purposes of the REIT requirements, we do not treat these loans as TRS securities for purposes of the TRS asset limitation. However, no assurance can be provided that the IRS may not successfully assert that such loans should be treated as securities of our TRSs, which could adversely impact our qualification as a REIT. In addition, our TRSs have obtained financing in transactions in which we and our other subsidiaries have provided guaranties and similar credit support. Although we believe that these financings are properly treated as financings of our TRSs for U.S. federal income tax purposes, no assurance can be provided that the IRS would not assert that such financings should be treated as issued by other entities in our structure, which could impact our compliance with the TRS limitation and the other REIT requirements. While we will be monitoring the aggregate value of the securities of our TRSs and intend to conduct our affairs so that such securities will represent less than 20% of the value of our total assets, there can be no assurance that we will be able to comply with the TRS limitation in all market conditions. Further, the TRS rules limit the deductibility of interest paid or accrued by a TRS to its parent REIT to assure that the TRS is subject to an appropriate level of corporate taxation. The rules also impose a 100% excise tax on certain transactions between a TRS and its parent REIT that are not conducted on an arm’s-length basis. The tax on prohibited transactions limits our ability to engage in certain types of transactions, including certain methods of securitizing loans, which would be treated as sales for U.S. federal income tax purposes. A REIT’s net income from prohibited transactions is subject to a 100% tax. In general, prohibited transactions are sales or other dispositions of property, other than foreclosure property, but including loans, held as inventory or primarily for sale to customers in the ordinary course of business. We might be subject to this tax if we were to sell or securitize loans in a manner that was treated as a sale of the loans as inventory for U.S. federal income tax purposes. Therefore, in order to avoid the prohibited transactions tax, we may choose not to engage in certain sales of loans, other than through a TRS, and we may be required to limit the structures we use for our securitization transactions, even though such sales or structures might otherwise be beneficial for us. Risks related to COVID-19 Complying with REIT requirements may limit our ability to hedge effectively. The REIT provisions of the Internal Revenue Code may limit our ability to hedge our assets and operations. Under these provisions, any income that we generate from transactions intended to hedge our interest rate exposure will be excluded from gross income for purposes of the REIT 75% and 95% gross income tests if (i) the instrument (A) hedges interest rate risk on liabilities used to carry or acquire real estate assets or certain other specified types of risk, or (B) hedges an instrument described in clause (A) for a period following the extinguishment of the liability or the disposition of the asset that was previously hedged by the hedged instrument, and (ii) such instrument is properly identified under applicable Treasury Regulations. Income from hedging transactions that do not meet these requirements will generally constitute non-qualifying income for purposes of both the REIT 75% and 95% gross income tests. As a result of these rules, we may have to limit our use of hedging techniques that might otherwise be advantageous or implement those hedges through a TRS. This could increase the cost of our hedging activities because our TRS would be subject to tax on gains or the limits on our use of hedging techniques could expose us to greater risks associated with changes in interest rates than we would otherwise want to bear. In addition, losses in our TRS will generally not provide any tax benefit to us, although subject to limitation, such losses may be carried forward to offset future taxable income of the TRS. Legislative, regulatory, or administrative changes could adversely affect us. The U.S. federal income tax laws and regulations governing REITs and their stockholders, as well as the administrative interpretations of those laws and regulations, are constantly under review and may be changed at any time, possibly with retroactive effect. Recently, the Biden administration has indicated an intention to enact tax legislation that could impact the taxation of an investment in our common stock. No assurance can be given as to whether, when, or in what form, the U.S. federal income tax laws applicable to us and our stockholders may be enacted. Changes to the U.S. federal income tax laws and interpretations of U.S. federal tax laws could adversely affect an investment in our common stock. Your investment has various U.S. federal income tax risks. We urge you to consult your tax advisor concerning the effects of U.S. federal, state, local and foreign tax laws to you regarding an investment in shares of our common stock. The current outbreak and spread of the COVID-19 outbreak has disrupted, and is likely to further cause severe disruptions in, the U.S. and global economies and financial markets and create widespread business continuity and viability issues. COVID-19 is having significant repercussions across regional, national and global economies and financial markets, and could trigger further periods of regional, national and global economic slowdown or regional, national or global recessions. COVID-19 continues to adversely impact regional, national and global economic activity and has contributed to significant volatility and negative pressure in financial markets. The impact of the outbreak continues to rapidly evolve. In an attempt to control COVID-19 the Federal government and most states and/or local governments, including the state in which we are headquartered and in regions where our projects and other investments are located or where they are managed, have implemented various restrictions, rules, or guidelines including quarantines, restrictions on travel, “shelter in place”, “stay at home”, or “safer at home” rules, restrictions on types of business that may continue to operate, and/ or restrictions on types of construction projects allowed. While some of these restrictions have been relaxed or phased out, many of these or similar restrictions remain in place, continue to be implemented, or additional restrictions are being considered. Although, in certain cases, exceptions may be available for certain essential operations and businesses which generally include the renewable energy projects | 3 5 HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 1A. RISK FACTORS in which we invest, there is no assurance that such exceptions will enable us to avoid adverse effects to our results of operations and business. Further, such actions create disruption in energy efficiency, renewable energy, real estate and other climate solutions markets and adversely impact a number of industries. We believe that our ability to operate and our level of business activity has been, and will in all likelihood continue to be, impacted by effects of COVID-19 and could in the future be impacted by another pandemic and that such impacts could adversely affect the profitability of our business, as well as the values of, and the cash flows from, the assets we own. For example, the effects of COVID-19 or another pandemic could adversely impact our financial condition and results of operations due to, among other factors: z interrupted service and availability of personnel, including our executive officers and other employees that are part of our management team and an inability to recruit, attract and retain skilled personnel-to the extent our management or personnel are impacted by the outbreak of pandemic or epidemic disease and are not available or allowed to conduct work, our business and operating results may be negatively impacted; z difficulty accessing debt and equity capital on attractive terms, or at all, and severe disruption or instability in the global financial markets or deterioration in credit and financing conditions may affect our ability or the ability of our climate solutions projects and our ultimate off-taker or project users to make regular payments of principal, interest or project revenue (e.g., due to unemployment, underemployment, or reduced income or revenues) or to access savings or capital necessary to fund business operations or replace or renew maturing liabilities on a timely basis, and may adversely affect the valuation of financial assets and liabilities, any of which could result in the inability to make payments under our borrowing facilities or notes, affect our or our projects’ ability to meet liquidity, net worth, and leverage covenants under borrowing facilities or have a material adverse effect on the value of investments we hold or on our business, financial condition, results of operations and cash flows; z temporary or lasting changes involving the status, practices and procedures of our operations or our projects or our projects’ sponsors’ operations, including with respect to new originations of investments - to the extent we elect or are required to limit or be more selective in making new originations of investments, we may strain our relationships with business partners, customers and counterparties, breach actual or perceived obligations to them, and be subject to litigation and claims from such partners, customers and counterparties, any of which could have a material adverse effect on our reputation, business, financial condition, results of operations and cash flows; moreover, some of our ultimate off- taker or project users’ operations, or our operations, the climate solutions markets or projects and our ultimate off-taker or project users have not been able to and others may not be able to function effectively because of, among other factors, disruptions in the normal operation of climate solutions markets or projects, any inability to access short-term or long-term financing, a disruption in the market for securitization transactions, or the inability to access these markets or execute securitization transactions due to negative impacts to our, our projects or our ultimate off-taker or project users financial condition or operating capabilities resulting from the COVID-19 pandemic or future pandemics; any or all of these impacts could result in reduced net investment income and cash flow, as well as an impairment of our investments which reductions and impairments could be material; z to the extent ultimate off-taker or other project users that have been negatively impacted by the COVID-19 or other pandemics do not timely remit payments of principal, interest or other payments (whether due to an inability to make such payments, an unwillingness to make such payments, or a waiver of the requirement to make such payments on a timely basis or at all, including under the terms of any applicable forbearance, modification, or maturity extension agreement or program (which forbearance, waiver, or maturity extension may be available as a result of a government-sponsored or -imposed program or under any such agreement or program we or our project sponsors may otherwise offer)), then the value of our investments will likely be impaired, potentially materially; moreover, to the extent any such pandemic impacts local, regional or national economic conditions, the value of a climate solutions project is likely to decline, which would likely negatively impact the value of our investments, potentially materially; z some of our climate solutions projects are being constructed and others are subject to ongoing maintenance; planned construction or maintenance of some of these projects have not been able to proceed on a timely basis or at all and others may be similarly affected as a result of being negatively impacted by the COVID-19 pandemic and could be similarly affected by a future pandemic, including due to operating disruptions or government mandated moratoriums on construction, development or redevelopment or the inability to source the necessary construction personnel, equipment or parts; all of the foregoing factors would likely negatively impact the value of our investments, potentially materially; z the inability of our project sponsors to operate in affected areas, including the bankruptcy of one or more project sponsors or their suppliers, or inability of our internal resources to effectively manage our investments in certain of their activities or perform certain administration functions; z the inability of other third-party vendors we rely on to conduct our business to operate effectively and continue to support our business and operations, including vendors that provide IT services, legal and accounting services, or other operational support services; z the inability of our or our investments’ counterparties to make or satisfy the conditions, covenants or representations and warranties in agreements they have entered into with us or our counterparties; and z our ability to ensure operational continuity in the event our business continuity plan is not effective or ineffectually implemented or deployed during a disruption. COVID-19 or a future pandemic and the impacts thereof on the current financial, economic and capital markets environments and other areas are difficult to predict and could present material uncertainty and risk with respect to our performance, financial condition, volume of business, results of operations and cash flows. To the extent the COVID-19 or a future pandemic adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described in this ‘‘Risk Factors’’ section, as well as the Risk Factors in the Form 10-K, such as those relating to changes in interest rates, declining demand for our projects due to declining costs of traditionally-sourced energy, the lack of liquidity of our assets and investments, changes in the fair value of our assets, negative market conditions, our dependence on third-party contractual arrangements, our dependence on the availability of capital, changes in credit ratings assigned to our assets, counterparties to repurchase transactions’ defaulting on their obligations and our investments’ subjectivity to delinquency, foreclosure and loss. 3 6 | HANNON ARMSTRONG | 2021 ANNUAL REPORT PA R T I ITEM 4.

Overview We invest in climate solutions developed or sponsored by leading companies in the energy efficiency, renewable energy and other sustainable infrastructure markets. We believe we are one of the first U.S. public companies solely dedicated to climate solutions. Our goal is to generate attractive returns from a diversified portfolio of project company investments with long-term, predictable cash flows from proven technologies that reduce carbon emissions or increase resilience to climate change. We are internally managed, and our management team has extensive relevant industry knowledge and experience, dating back more than 30 years. We have long-standing relationships with the leading energy service companies (“ESCOs”), manufacturers, project developers, utilities, owners and operators which provide recurring, programmatic investment and fee-generating opportunities. Additionally, we have relationships with leading banks, investment banks, and institutional investors from which we are referred additional investment and fee generating opportunities. We completed approximately $1.7 billion of transactions during 2021, compared to approximately $1.9 billion during 2020. As of December 31, 2021, we held approximately $3.6 billion of Market Conditions As a result of increasing global awareness of and aversion to climate change impacts, we believe the climate solutions markets in which we invest, and investment in climate solutions more broadly, will continue to grow as the impact of climate change increases. In January 2022, National Oceanic and Atmospheric Administration (“NOAA”) reported that globally, 2021 was the fourth warmest year on record, with all six of the warmest years on record having occurred since 2012. Further, communities across the globe are increasingly experiencing the destructive economic impacts of climate change, which are only expected to increase in frequency and severity. According to NOAA, there were 20 natural disaster events in the United States in 2021, with an estimated individual cost of greater than $1 billion and an aggregate cost of approximately $145 billion. NOAA reports, that the total cost of climate related disasters over the last five years exceeds $742 billion. In its Weather, Climate & Catastrophe Insight: 2021 Annual Report, Aon reports that there were 401 natural catastrophe events globally in 2021, resulting in economic losses of $343 billion, making it the third costliest year on record. transactions on our balance sheet, which we refer to as our “Portfolio.” For those transactions that we choose not to hold on our balance sheet, we transfer all or a portion of the economics of the transaction, typically using securitization trusts, to institutional investors in exchange for cash and/or residual interests in the assets and in some cases, ongoing fees. As of December 31, 2021, we managed approximately $5.2 billion in these trusts or vehicles that are not consolidated on our balance sheet. When we combine these assets with our Portfolio, as of December 31, 2021, we manage approximately $8.8 billion of assets, which we refer to as our “Managed Assets”. Our investments have taken many forms, including equity, joint ventures, land ownership, lending, or other financing transactions. We also generate ongoing fees through off-balance sheet securitization transactions, advisory services, and asset management. We use borrowings as part of our strategy to increase potential returns to our stockholders and have available a broad range of financing sources including non-recourse or recourse debt, equity and off-balance sheet securitization structures. See Item 1. Business for a further discussion of our business, investing strategy, and financing strategy. In its Energy Efficiency 2021 report, the International Energy Agency (“IEA”) estimates global spending on energy efficiency at almost $300 billion, and forecasts that overall investment in energy efficiency will need to triple by 2030 in order to achieve certain net-zero carbon by 2050 targets. Given that many projects are often self-financed (especially energy efficiency), we believe our total addressable market is likely a subset of these overall industry estimates. However, we believe these estimates are reliable indicators of market trends. These positive industry trends coupled with the increasing environmental and economic imperative to reduce carbon emissions are expected to further broaden our investable universe. Investments in energy efficiency as a service allow organizations to avoid the upfront costs of efficiency investments by paying for efficiency-enabled cost savings as operating rather than capital expenses. In its Annual Energy Outlook 2021, the U.S. Energy Information Administration (“EIA”) estimates that decreasing energy intensity resulting from energy efficiency improvements will continue until at least 2050. In addition, Lazard’s 2021 Levelized Cost of Energy Analysis shows that renewables 4 0 | HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7. mANAGemeNT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND ReSULTS OF OPeRATIONS PA R T I I continue to be competitive with traditional generation sources on a new-built cost basis with certain renewable technologies achieving competitiveness with existing conventional generation technologies on a marginal basis, making renewables even more attractive investment targets. Further, in its New Energy Outlook 2021, Bloomberg New Energy Finance (“BNEF”) states global annual investment in energy supply and infrastructure will need to double from around $1.7 trillion per year today to between $3.1 trillion and $5.8 trillion per year on average over the next thirty years. We expect the federal government to take, and they have taken, certain actions which are supportive of the industry for climate solutions. In 2021, Congress passed the Infrastructure Investment and Jobs Act which provides funding opportunities for a variety of traditional infrastructure projects including approximately $65 billion for energy and electric grid development which is critical for further development of renewable energy projects. In December 2021, President Biden signed an executive order committing the U.S. federal government to achieve 100 percent carbon pollution-free electricity and to achieve a net-zero emissions building portfolio by 2045, including a 50 percent emissions reduction from buildings, campuses, and installations by 2032 from 2008 levels. Corporates are also responding to climate change risks - in part through renewable energy sourcing commitments. BNEF states that in 2021, a record 31 gigawatts of clean energy were purchased through corporate PPAs, an increase of over 20% from the previous year, with two-thirds of this purchasing occurring in the United States. In its 2021 Annual Report, the RE 100, a global corporate leadership initiative bringing together influential businesses committed to 100% renewable electricity, reported that over 300 multinational companies have pledged to achieve 100% renewable energy with an average target date of 2030, with the average target year for North American companies being 2027. Federal Energy Savings Performance Contracts (“ESPCs”) are an example of a public-private partnership that eliminate the need for a federal agency to find appropriated funds to replace, operate, and maintain energy-intensive equipment while also providing multiple ancillary benefits, including saving taxpayer dollars currently spent on energy consumption, improving conditions for federal workers and service men and women, and creating private sector jobs. Support for ESPCs remain bipartisan, and the presidential administration is expected to continue to support the program. Almost $3.4 billion in ESPC contracts have been awarded over the last five government fiscal years. Factors Impacting our Operating Results We expect that our results of operations will be affected by a number of factors and will primarily depend on the size of our Portfolio, including the mix of transactions which we hold in our Portfolio, the income we receive from securitizations, syndications and other services, our Portfolio’s credit risk profile, changes in market interest rates, commodity prices, federal, state and/or municipal governmental policies, general market conditions in local, regional and national economies, our ability to qualify as a REIT and maintain our exemption from registration as an investment company under the 1940 Act and, the impact of climate change, and the impact of the novel coronavirus (COVID-19). While we believe that the long-term growth prospects for our business remain positive, volatility in financial markets and higher inflation along with interest rate movements could impact the markets we serve. The Federal Reserve Board of Governors has indicated that it will begin to reduce its asset purchases and increase the rate at which banks lend to one another (known as the federal funds rate) while monitoring the economic outlook. We believe higher interest rates and inflation are likely to have a minimal impact on our existing portfolio, and that PPA prices for future deals are rising to compensate with regards to new investments. See “Item 7A. Quantitative and Qualitative Disclosures about Market Risk-Interest Rate and Borrowing Risks” for an analysis of the impact of rates on our business. According to the Department of Energy, average annual Henry Hub natural gas prices for the years from 2012 to 2021 were over 45% lower than the same prices from 2002 to 2011, and its 2021 outlook forecasts that prices will stay below pre-2010 levels through 2050. As wholesale electricity prices are closely tied to wholesale natural gas prices in many parts of the United States, lower natural gas prices have negatively impacted, and are expected to continue to negatively impact, renewable energy projects that sell wholesale power on a “merchant” basis at spot market prices. For more detail on commodity price impacts, see “Item 7A. Quantitative and Qualitative Disclosures about Market Risk-Commodity Price Risk”. We attempt to mitigate our exposure to these low commodity prices and future volatility, as well as any credit risk associated with these prices, by acquiring projects with contracted revenues, negotiating certain structural protections such as preferred returns, and through active asset management and portfolio monitoring. Similarly, we seek to manage credit risk that might arise from commodity price declines through our due diligence and underwriting processes, strong structural protections in our transaction agreements with customers, and active asset management and portfolio monitoring. Notwithstanding any concerns that current market conditions have raised for our business, we believe significant opportunities exist for us to grow our business. As a long-term participant committed to providing capital for climate solutions, we plan to continue to fund projects that meet our underwriting standards and look for opportunities to expand our business. Portfolio Size The size of our Portfolio will be a key revenue driver. Generally, as the size of our Portfolio on our balance sheet grows the amount of our revenue will increase. Our Portfolio may grow at an uneven pace as opportunities to originate new assets may be irregularly timed, and the timing and extent of our success in such originations cannot be predicted. To the extent the size of our Portfolio changes due to equity method investment activity, the income or loss from such investments will not be included in revenue but are reflected as income (loss) from equity method investments in our income statement and will vary | 4 1 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7. mANAGemeNT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND ReSULTS OF OPeRATIONS PA R T I I over time. In addition, we may decide for any particular asset that we should securitize or otherwise sell a portion, or all, of the asset, which would result in gain on sale of receivables and investments or fee income as described below. The level of portfolio activity will fluctuate from period to period based upon the market demand for the capital we provide, our view of economic fundamentals including interest rates, the present mix of our Portfolio, our ability to identify new opportunities that meet our investment criteria, the volume of projects that have advanced to stages where we believe a transaction is appropriate, seasonality in our activities and in the various projects where we may provide debt or equity and our ability to consummate the identified opportunities, including as a result of our available capital. The level of our new origination activity, the percentage of the originations that we choose to retain on our balance sheet and the related income, will directly impact our interest and rental revenue and income from equity method investments. Income from Securitization, Syndication and Other Services We earn gain on sale of financial assets or fee income by securitizing or selling all or a portion of certain transactions. For transactions that we securitize via a non-consolidated trust, we recognize a gain on the securitization. The gain may be comprised of either or both cash received and a residual interest in securitized assets. We may also recognize additional income from servicing fees from these securitized assets over the life of the asset. We view the revenue from such activities as a valuable component of our earnings and an important source of franchise value. In many cases, we arrange the securitization of the loan or other asset prior to originating the transaction and thus avoid exposure to credit spread and interest rate risks. In these cases, we avoid funding risks for these financings or other assets given that our securitization partners contractually agree to fund such assets before the origination transaction is completed. We also generate fee income for syndications where we arrange financings that are held by other investors or if we sell existing transactions to other investors. In these transactions, unless we decide to hold a portion of the economic interest of the transaction on our balance sheet, we have no exposure to risks related to ownership of those financings. We may charge advisory, retainer or other fees, including through our broker dealer subsidiary. The total amount of income from securitizations, syndications, and other services will vary from quarter to quarter depending on various factors, including the level of our originations, the duration, credit quality and types of assets we originate, current and anticipated future interest rates, the impact on our leverage, the mix of our Portfolio and our need to tailor our mix of assets in order to allow us to qualify as a REIT for U.S. federal income tax purposes and maintain our exemption from registration under the 1940 Act. Credit Risks We source and identify quality opportunities within our broad areas of expertise and apply our rigorous underwriting processes to our transactions, which, we believe, will generally enable us to minimize our credit losses and maintain our current level of financing costs. In the case of various renewable energy and other sustainable infrastructure projects, we will be exposed to the credit risk of the obligor of the project’s PPA or other long-term contractual revenue commitments, as well as to the credit risk of certain suppliers and project operators. While we do not anticipate facing significant credit risk in our assets related to government energy efficiency projects, we are subject to varying degrees of credit risk in these projects in relation to payment guarantees provided by ESCOs that are required in the event that certain energy savings are not realized by the customer. We are also exposed to credit risk in our other projects that do not benefit from governments as the obligor such as on balance sheet financing of projects undertaken by universities, schools and hospitals, as well as privately owned commercial projects. We have extended mezzanine loans to various special purpose entities which own residential or community solar projects, and the ultimate repayment of those loans is dependent on the creditworthiness of the related residential obligors. As a result of investing in these and other mezzanine loans, we are exposed to additional credit risk. In certain instances interest is paid on our mezzanine loans in-kind, which increases our outstanding loan balances and causes the ultimate repayment of cash to occur later. We seek to manage credit risk through thorough due diligence and underwriting processes, strong structural protections in our transaction agreements with customers and continual, active asset management and portfolio monitoring. Nevertheless, unanticipated credit losses could occur and during periods of economic downturn in the global economy, our exposure to credit risks from obligors increases, and our efforts to monitor and mitigate the associated risks may not be effective in reducing our credit losses. See Item 7A. Quantitative and Qualitative Disclosures about Credit Risks for further information on our credit risks and see Note 6 to our audited financial statements in this Form 10-K for additional detail of the credit risks surrounding our Portfolio. Changes in market Interest Rates and Liquidity Interest rate risk is highly sensitive to many factors, including governmental monetary and tax policies, domestic and international economic and political considerations and other factors beyond our control. We are subject to interest rate risk in connection with new asset originations and our borrowings, including our revolving credit facilities, and in the future, to the extent we choose to enter into any new floating rate assets, revolving credit facilities or other borrowings. See Item 7A. Quantitative and Qualitative Disclosures about Market Risk for further information on interest rates risks and liquidity. Commodity Prices When we make investments in a project that act as a substitute for an underlying commodity, we may be exposed to volatility in prices for that commodity. For example, the performance of renewable energy projects that produce electricity can be impacted by volatility in the market prices of various forms of energy, including electricity, coal and natural gas. This is especially true for utility scale projects that sell power on a wholesale basis such as many of our Grid-Connected projects as opposed to Behind-the-Meter projects which compete against the retail or delivered costs of electricity which includes the cost of transmitting and distributing the electricity to the end user. See Item 7A. Quantitative and Qualitative Disclosures about Market Risk for further information on the impact of commodity prices. Government Policies We make investments in renewable energy projects that typically depend in part on various federal, state or local governmental policies that support or enhance the project’s economic feasibility. Such policies may include governmental initiatives, laws and regulations designed to 4 2 | HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7. mANAGemeNT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND ReSULTS OF OPeRATIONS PA R T I I reduce energy usage and impact the use of renewable energy or the investment in, and the use of, climate solutions. Policies and incentives provided by the U.S. federal government may include tax credits (with some of these tax credits that are related to renewable energy scheduled to be reduced or eliminated in the future), tax deductions, bonus depreciation, federal grants and loan guarantees, and energy market regulations. The value of tax credits, deductions and incentives and how they can be realized may be impacted by changes in tax laws, rates, or regulations. Incentives provided by state and local governments may include an RPS or similar clean energy standard, which specify the portion of the power utilized by local utilities that must be derived from renewable or clean energy sources as well as the state or local government sponsored programs where the financing of energy efficiency or renewable energy projects is repaid through an assessment in the property tax bill in a program commonly referred to as PACE. Additionally, certain states have implemented feed-in or net metering tariffs, pursuant to which electricity generated from renewable energy sources is purchased at a higher rate than prevailing wholesale rates. Other incentives include tariffs, tax incentives and other cash and non-cash payments. Governmental agencies, commercial entities and developers of climate solutions projects frequently depend on these policies and incentives to help defray the costs of various projects. Government regulations also impact the terms of third party financing provided to support these projects. If any of these government policies, incentives or regulations are adversely amended, delayed, eliminated, reduced, retroactively changed or not extended beyond their current expiration dates or there is a negative impact from the recent federal law changes or proposals, the operating results of the projects we finance and the demand for, and the returns available from our investments may decline, which could harm our business. Impacts of Climate Change on our Future Operations As our business is focused on reducing carbon emissions and increasing resiliency to climate change, we are impacted by the effects of climate change and various related regulatory responses. In managing our business, we consider the potential impacts to our operations that may result in certain climate-related scenarios. We have implemented the recommendations of the TCFD, which provides a framework to consider and disclose our processes for managing the risks and opportunities associated with climate change. We have disclosed the components of the TCFD framework throughout this document. The following tables highlight our evaluation of potential impacts to our business in two climate related scenarios as well as our resilience to and strategy for handling the potential impacts. Transition Risks and Opportunities - We believe our Portfolio will be impacted by the transition risks and opportunities contemplated by the Paris Accords and the achievement of its objectives. Scenario 1 - Global action is taken to limit the global temperature increase to 1.5 degrees Celsius above pre-industrial levels Assumption Qualitative impacts Quantitative impacts If the overall price level of RECs increased by 5% we would not expect a material impact to the overall cash flows from our existing investments. This is largely due to the lower value of RECs in comparison to power prices in most of the markets where our investments are located. The price of Renewable energy Credits (“ReCs”) or similar structures increase as more aggressive renewable portfolio standards and corporate renewable energy targets are implemented Increased expected cash flows and financial returns for certain of our investments to the extent the RECs are sold at higher market prices. Increased debt/lease service coverage ratio for the obligors of our renewable energy debt investments and solar real estate leases that sell RECs at higher market pricing. The resulting increase in cash flows may also allow us to apply greater financial leverage to these investments and enhance our profitability. If there was a material increase in value associated with RECs, it is likely that more renewable energy projects would be developed in geographic areas where the RECs were more valuable, leading to more potential investment opportunities for us. Considerations of and impact on our management strategy We may identify more investment opportunities resulting from the increased REC value. In addition, to the extent that our investments become more valuable we would consider whether it would be more economical to our stockholders to either monetize the investment given the increase in value or continue to hold in our Portfolio and maximize our returns from adding additional leverage to our financing. | 4 3 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7. mANAGemeNT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND ReSULTS OF OPeRATIONS PA R T I I Assumption Qualitative impacts Quantitative impacts A carbon tax or similar carbon pricing mechanism is implemented by governmental authorities which may cause an increase to (i) power prices, (ii) operating costs for certain entities, and (iii) the competitiveness of renewable energy, energy efficiency and storage projects A significant increase in research and re-development investment in renewable energy, energy storage, and energy efficiency technologies by public and private entities Increased cash flows and financial returns from certain investments to the extent power is sold at higher market prices due to the increase in cost imposed on fossil fueled energy projects. Increases in the debt/lease service coverage ratio for the obligors of our renewable energy debt investments and solar real estate leases that sell power at higher market pricing. The resulting increase in cash flows may also allow us to apply greater financial leverage to these investments and enhance our profitability. Increased energy cost savings from energy efficiency solutions. Increased competitiveness of renewable energy projects with fossil fueled power plants, due to an increase in power prices. An increase in the items mentioned above may increase the volume of assets available in which we can invest. However, the implementation of a carbon tax may also have a negative impact on the financial health of utilities and corporate entities who also purchase power from renewable energy projects in which we have invested. The credit ratings of these entities may be downgraded due to additional operating expenses resulting from a carbon tax. A credit rating downgrade may reduce the amount of financial leverage we are able to utilize. If this were to occur, our overall profitability could decline. Continued decreases in cost could make renewable energy, energy storage, and energy efficiency technologies more cost competitive. As a result, we may experience an increase in investment opportunities available to us. Significant growth in positive public sentiment for climate solutions investment Increased demand for investment in climate solutions may increase the volume of transactions in which we may invest, reduce our overall cost of capital and increase our profitability. 4 4 | A portion of our Portfolio is exposed to changes in the market price of power. Whether it is due to sales of energy at the then current market price or through a re-contracting of fixed price power purchase agreements. Under a scenario where a carbon tax drives the price of power up by 10%, our wind equity investments may generate approximately 7% in additional cash flows over their life as compared to the cash flow the investments are expected to generate under the current baseline scenario. We would not expect a material impact to our solar equity, renewable energy debt, solar real estate or energy efficiency investments. Considerations of and impact on our management strategy In relation to new business, there is the potential that more competitors enter our markets and put pressure on our asset pricing strategies as renewable energy and energy efficiency projects become more cost competitive with fossil fuel electricity generation assets. We are constantly reviewing our pricing strategies and would continue to do so in this scenario to understand how we can continue to make investments with acceptable risk adjusted returns. In addition, to the extent that our investments become more valuable we would consider whether it would be more economical to our stockholders to either monetize the investment given the increase in value or continue to hold in our Portfolio and maximize our returns from adding additional leverage to our financing. Given the nature of our business activities and focus on structuring transactions to meet the capital needs of our clients, it is difficult to reliably quantify the positive impact on our investment opportunities. However, we would expect to achieve accretive economics from this assumption. Given the nature of our business activities and focus on structuring transactions to meet the capital needs of our clients, it is difficult to reliably quantify the positive impact on our investment opportunities. However, we would expect to achieve accretive economics from this assumption. In the development of our investment strategies we would consider investment in different technologies that we may not have historically invested based upon the additional development and maturation gained through the prospective increase in research and development. Additionally, the lower cost of projects may influence the amount of investment we would make in each opportunity. An increased demand for climate solutions may increase competition and influence our pricing strategy. We would continue to review our pricing strategies with these opportunities. HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7. mANAGemeNT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND ReSULTS OF OPeRATIONS PA R T I I Assumption Qualitative impacts Quantitative impacts Customer preference shifting to match electricity demand with carbon-free energy generation from resources on the same regional grids Increased demand for climate solutions investment in particular regions increase the volume of transactions in which we may invest, reduce our overall cost of capital and increase our profitability. Given the nature of our business activities and focus on structuring transactions to meet the capital needs of our clients, it is difficult to reliably quantify the positive impact on our investment opportunities. However, we would expect to achieve accretive economics from this assumption. Scenario 2 - Global temperatures increase more than 2 degrees Celsius above pre-industrial levels Assumption Qualitative impacts Quantitative impacts Given the nature of our business activities and focus on structuring transactions to meet the capital needs of our clients, it is difficult to reliably quantify the impact on our investment opportunities. However, we would expect to achieve accretive economics from this assumption. Given the nature of our business activities and focus on structuring transactions to meet the capital needs of our clients, it is difficult to reliably quantify the positive impact on our investment opportunities. However, we would expect to achieve accretive economics from this assumption. We believe any mentioned impacts that are realized, are short-term in nature and we would not expect a material impact on our investments. No meaningful government policy to shift the trajectory of global climate change An increase in demand for climate change resiliency solutions Greater variability and instability in the commodity markets Given current trends, even without an increase in government support, we might expect increased demand for climate solutions due to the improving economics and cost competitiveness of these technologies. Such growth in demand may increase the volume of investment opportunities available to us. Flooding and storm surges may become more frequent, resulting in an increase in demand for storm water management assets. Greater instability in the power grid may increase the demand for on-site and distributed power generation systems and battery storage. If the above events occur, we may experience an increase in the volume of investment opportunities available to us. Potential increases in the price of commodities (e.g., natural gas) due to climate change induced supply chain and transport disruptions, such as a major hurricane striking a series of gulf coast pipelines, may drive power prices higher, thus increasing financial returns from certain of our investments to the extent the power is sold at market prices rather than under fixed price contracts. However, climate change-related impacts to the amount of potable water supplies, such as irregular rainfall and salt water intrusion, may drive increases in the price of water. These increases in cost may increase the demand for assets that increase water use efficiency, resulting in an increase in the volume of investment opportunities available to us. Considerations of and impact on our management strategy Changing consumer preference can drive investments in renewable deployments in new areas to improve the localization of clean energy supplies and can drive development of multi-technology portfolios of intelligent generation and storage, both of which may increase the total investment opportunities available to us. Considerations of and impact to our management strategy The increased demand in climate solutions may increase competition and influence our pricing strategy. The increased demand in climate solutions may increase competition and influence our pricing strategy. We currently have risk management processes which include a recurring review of our investments through our portfolio management function to assess any increasing operational costs of our investments. For our Portfolio, we will actively manage the risk to make appropriate adjustments to budget approvals, operational approvals, and other asset management tasks. For any new investments, we make conservative assumptions to protect our investments from such types of pricing volatility and will continue to do so, including new assumptions around commodity volatility as relevant. | 4 5 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7. mANAGemeNT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND ReSULTS OF OPeRATIONS PA R T I I Physical Risks and Opportunities - Given the assessments of the United Nation’s Intergovernmental Panel on Climate Change and other leading climate research organizations regarding the probability of a 1.5 Celsius increase in global temperature and serious climatic impacts even with the most aggressive emissions reduction initiatives, we believe our Portfolio will be impacted by physical risks regardless of the actions taken as discussed above. We assume the types of risks to which our Portfolio is exposed are similar under either Scenario 1 or 2 (albeit at varying degrees of severity). Scenario 1 - Global action is taken to limit the global temperature increase to 1.5 degrees Celsius above pre-industrial levels and Scenario 2 - Global temperatures increase more than 2 degrees Celsius above pre-industrial levels. Assumption Qualitative impacts Quantitative impacts Increased (i) flooding events due to heavier rainfalls and increased storm surge due to rising sea levels, (ii) the probability and severity of wildfires and (iii) increased frequency and severity of storms and other weather- related events Our existing investments in low lying areas are exposed to potential flooding events and other storm damage and such events may cause construction delays, operational shutdowns, and more significant site damage. We would not expect a material risk to the cash flows from our investments as we typically require insurance coverage for these events where the project owner bears this cost. Refer to later discussion on the impacts of the increase in insurance costs. A portion of our investments are located in high wildfire risk regions and are exposed to catastrophic damage from wildfire events. We would not expect a material risk to the cash flows from our investments as we typically require insurance coverage for these events where the project owner bears this cost. Refer to later discussion on the impacts of the increase in insurance costs. Solar energy assets that are not in the direct path of wildfires but are within the proximity thereof may have reduced power production due to ash soiling on the panels or reduced solar insolation due to ash clouds. The potential impact of additional soiling of panels or ash clouds was assessed and is not expected to have a material impact on the cashflows and value of our portfolio. If the events above were to occur, we may experience reduced cash flows and financial returns from these investments, which may cause us to reduce the amount of financial leverage we utilize and cause a decline in our overall profitability. Considerations of and impact to our management strategy When underwriting our investments we negotiate structural protections to mitigate any loss we may incur from operations or inability of the projects to operate (this includes project insurance). For any new investment opportunities we would evaluate the exposure to rising sea levels and structure our investment terms such that we protect our invested capital. When underwriting our investments we negotiate structural protections to mitigate any loss we may incur from operations or inability of the projects to operate (this includes project insurance). For any new investment opportunities we would evaluate the exposure to wildfires and structure our investment terms such that we protect our invested capital. To the extent this became a material issue we would seek out protections to mitigate any impact of this, such as adding panel washing requirements to contracts. 4 6 | HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7. mANAGemeNT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND ReSULTS OF OPeRATIONS PA R T I I Assumption Qualitative impacts Quantitative impacts Solar portfolio production can be affected by an increase in global temperature depending on the geography. If solar production decreases by 5% we may expect there to be a 8% decrease in expected cash flows from our solar equity investments. High temperatures have a significant efficiency impact on wind turbines as high temperature faults create more wear and tear on equipment. If wind production decreases by 5% the cash flows from our wind equity investments would be expected to decrease by 5%. We would not expect a material impact on our renewable energy debt, solar real estate and energy efficiency investments. An increase in operating expenses would result and if there was 5% higher operating expenses the cash flows from our wind equity investments would be expected to decrease by 1%. If there were both a decrease in production of 5% and higher operating expenses of 5% our cash flows from our wind equity and solar equity investments would be expected to decline by 8% and 9%, respectively. We would not expect a material impact on our renewable energy debt, solar real estate and energy efficiency investments. The impact of water scarcity and increased prices to our Portfolio is not expected to have a material impact on the cash flows of our investments. Operational performance of the projects in which we invest are impacted by the global temperature increase A decrease in performance and power generation of the solar and wind energy assets related to our investments, as the performance of these assets vary based upon the ambient temperatures (in the case of solar) and air density (in the case of wind). Both conditions may be caused by increases in global temperatures. An increase in water scarcity potentially resulting in an increase in the price of water Increased wind variability and increased wear on wind turbine components, which may increase operating costs. Increased operating costs and lower generation from the increase in temperatures may reduce our expected cash flows and financial returns from our investments, which may cause us to reduce the amount of financial leverage we utilize and cause a decline in our overall profitability. Water is used to clean the panels on solar energy assets to maintain their efficiency. An increase in water prices may reduce the cash flows and financial returns from our related investments, which may cause us to reduce the amount of financial leverage we utilize and cause a decline in our overall profitability. Climate change related impacts to the amount of potable water supplies, such as irregular rainfall and salt water intrusion, may drive increases in the price of water. These increases in cost may increase the demand for assets that increase water use efficiency resulting in an increase in the volume of investment opportunities available to us. Considerations of and impact to our management strategy When underwriting our investment opportunities we make conservative assumptions regarding performance and operational expenses that protect our returns from some level of unexpected performance or operation issues in the future. We will continue to adjust our assumptions as additional risks and severity of climate risk are assessed. We actively manage our Portfolio to preemptively and proactively address any operational or maintenance issues. To the extent this becomes a material matter we would seek out protections to mitigate any impact of additional water related costs. The increased demand in these projects may increase competition and influence our pricing strategy. | 4 7 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7. mANAGemeNT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND ReSULTS OF OPeRATIONS PA R T I I Assumption Qualitative impacts Quantitative impacts An increase in the cost, or a change in the availability of insurance In anticipation of climate change related physical risks, projects related to our investments in particularly vulnerable regions, such as low-lying coastal areas, may face increases in insurance costs. An increase in insurance costs may reduce the cash flows and financial returns from these investments and may cause us to reduce the amount of financial leverage we utilize and cause a decline in our overall profitability. Insurance policies are executed on an annual basis and in some regions the price of insurance could increase such that the cashflow and value of our projects in high risk geographic regions are affected. This increase in insurance cost would drive an increase in total operating expenses. We have estimated that an increase in operating expenses of 5% would be expected to reduce our cash flows from solar equity projects by 1%. We would not expect a material impact on our wind equity, renewable energy debt, solar real estate and energy efficiency investments. Considerations of and impact to our management strategy We require that the projects in which we invest are insured against casualty events that could impact our cash distributions. We continually evaluate whether there are superior asset or portfolio level policies that are available that optimize our insurance coverage and premium costs. Impact of COVID-19 The current outbreak of the novel coronavirus (COVID-19) is having an ongoing impact on the U.S., regional and global economies, the U.S. climate solutions market and the broader financial markets, including supply chain disruptions, tightening labor markets, and inflation. Our financial results for 2021 have not been adversely impacted by COVID-19 to a material degree. We believe that the cost- savings attributes of the projects in which we invest provide incentive to borrowers and other obligors to continue to make their contractual payments. COVID-19 and the current financial, economic and capital markets environment, and future developments in these and other areas present material uncertainty and risk with respect to our performance, financial condition, volume of business, results of operations and cash flows. We expect to continue to review and adjust our efforts as the circumstances and impacts of the pandemic develop and respond to the shifting business and financial landscape and heightened volatility in, among other things, financial markets as well as the general economy and the various federal, state and local guidelines on business operations. See the Risk Factors section of this Form 10-K for additional discuss of certain potential risks to our business arising from COVID-19. Critical Accounting Policies and Use of Estimates Our financial statements are prepared in accordance with GAAP, which requires the use of estimates and assumptions that involve the exercise of judgment and use of assumptions as to future uncertainties. The following discussion addresses the accounting policies that we use including areas that involve the use of significant estimates. Our most critical accounting policies involve decisions and assessments that could affect our reported assets and liabilities, as well as our reported revenues and expenses. We believe that all of the decisions and assessments upon which our financial statements are based are reasonable at the time made and based upon information available to us at that time. Our critical accounting policies and accounting estimates may be expanded over time. Those material accounting policies and estimates that we expect to be most critical to an investor’s understanding of our financial results and condition and require complex management judgment are discussed below. See Note 2 to our audited financial statements in this Form 10-K for further details on our accounting policies. We evaluate our critical accounting estimates and judgments on an ongoing basis and update them, as necessary, based on changing conditions. We have identified the following accounting policies as critical because they require significant judgments and assumptions about highly complex and inherently uncertain matters and the use of reasonably different estimates and assumptions could have a material impact on our reported results of operations or financial condition. 4 8 | Consolidation We account for our investment in entities that are considered voting or variable interest entities under ASC 810, Consolidation. We perform an ongoing assessment and make judgments to determine the primary beneficiary of each entity as required by ASC 810, which includes an assessment of the type and degree of control we have over the entity. If we would conclude that certain of these entities should be consolidated, we would include the entities’ assets, liabilities and related activity in our financial statements. Refer to discussion below relating to additional consolidation considerations related to the securitization of receivables. We further discuss our process for evaluating these judgments in Note 2 to our audited financial statements in this Form 10-K. equity method Investments For our non-consolidated equity investments, we generally determine our income allocations under the equity method of accounting based on the change in our claim on net assets of the investee entity as reported by the investee using a method commonly referred to as the hypothetical liquidation at book value method or (“HLBV”). This method uses a hypothetical liquidation scenario that may require judgment in its application and could have a material impact on our reported financial results. Any changes in this method of application HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7. mANAGemeNT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND ReSULTS OF OPeRATIONS PA R T I I or in certain assumptions could either increase or decrease our net income. We further discuss our process for applying this method of income allocations in Note 2 to our audited financial statements in this Form 10-K. Impairment of our Portfolio We evaluate the various assets in our Portfolio on at least a quarterly basis, and more frequently when economic or other conditions warrant such an evaluation, for delinquencies or other events that may indicate a potential impairment or specific consideration in the development of the allowance for credit losses. For our equity method investments and real estate, if an impairment charge is deemed appropriate it would be recorded in our income statement and reduce our net income. In addition, for our receivables, we make judgments about our expected losses related to the receivables in our Portfolio and record an allowance for credit losses on such receivables with a provision for loss on receivables in our income statement. We further discuss our process for evaluating these judgments in Note 2 to our audited financial statements in this Form 10-K. Results of Operations For a comparison of our results of operations for the fiscal years ended December 31, 2020 and December 31, 2019, see “Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our annual report on Form 10-K for the fiscal year ended December 31, 2020, filed with the SEC on February 22, 2021. We invest in climate solutions developed or sponsored by leading companies in the energy efficiency, renewable energy and other sustainable infrastructure markets. We believe we are one of the first U.S. public companies solely dedicated to such climate solutions. Our goal is to generate attractive returns from a diversified portfolio of project company investments with long-term, predictable cash flows that reduce carbon emissions or increase resilience to climate change. We completed approximately $1.7 billion of transactions during 2021, compared to approximately $1.9 billion during 2020. Our strategy includes holding a large portion of these transactions on our balance sheet. We refer to the transactions we hold on our balance sheet as of a given date as our “Portfolio”. Our Portfolio was approximately $3.6 billion as of December 31, 2021 and $2.9 billion December 31, 2020. Securitization of Financial Assets We have established various special purpose entities or securitization trusts for the purpose of securitizing certain receivables or other debt investments. We make judgments, based in part, on supporting legal opinions, on whether these entities should be consolidated as a variable interest entity, as defined in ASC 810, Consolidation, and whether the transfers to these entities are accounted for as a sale of a financial asset or a secured borrowing under ASC 860, Transfers and Servicing. If we would conclude that certain of these special purpose entities or securitization trusts should be consolidated, we would include the assets and liabilities of the entity and their related activity in our financial statements. If sale accounting is not met in these transactions it would be treated as a secured borrowing rather than a sale in our financial statements, which would result in reduced revenue in the current period and an increase in assets and non-recourse debt. We further discuss our process for evaluating these judgments in Note 2 to our audited financial statements in this Form 10-K. We also make assumptions regarding the fair value of our securitization assets in these transferred assets. If our determination of fair value is determined to be incorrect, our gain on sale of receivables and investments in our income statement and securitization assets on our balance sheet will be inaccurate. See Note 3 to our audited financial statements in this Form 10-K for a discussion around fair value measurements. Portfolio Our Por tfolio totaled approximately $3.6 billion as of December 31, 2021, and included approximately $1.9 billion of BTM assets and approximately $1.7 billion of GC assets. Approximately 49% of our Portfolio consisted of unconsolidated equity investments in renewable energy related projects. Approximately 41% consisted of fixed-rate government and commercial receivables and debt securities, which are classified as investments, on our balance sheet and approximately 10% of our Portfolio was real estate leased to renewable energy projects under long-term operating lease agreements. Our Portfolio consisted of over 285 transactions with an average size of $12 million and the weighted average remaining life of our Portfolio (excluding match-funded transactions) of approximately 17 years as of December 31, 2021. | 4 9 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7. mANAGemeNT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND ReSULTS OF OPeRATIONS PA R T I I The table below provides details on the interest rate and maturity of our receivables and debt securities as of December 31, 2021: (in millions) Fixed-rate receivables, interest rates less than 5.00% per annum $ Fixed-rate receivables, interest rates from 5.00% to 6.50% per annum(1) Fixed-rate receivables, interest rates from 6.50% to 8.00% per annum Fixed-rate receivables, interest rates greater than 8.00% per annum Receivables Less: Allowance for loss on receivables Receivables, net of allowance Fixed-rate investments, interest rates less than 5.00% per annum Fixed-rate investments, interest rates from 5.00% to 6.50% per annum TOTAL RECEIVABLES AND INVESTMENTS (1) Excludes receivables held-for-sale of $22 million.

These results do not include the Non-GAAP earnings adjustment related to equity method investments, which is discussed in the Non-GAAP Financial Measures section. z Interest and rental income increased by $11 million due to the addition of higher yielding assets and a larger portfolio. Gain on sale and fee income increased by $15 million primarily from a change in mix of assets being securitized, partially offset by lower advisory fee generating opportunities. z Interest expense for the year increased by approximately $30 million due to a one time $15 million loss on the redemption of the 2024 senior unsecured notes, as well as additional expense from a larger average outstanding debt balance partially offset by a lower cost of debt. Provision for loss on receivables decreased by $10 million compared to the prior period, as the provision related to the current year loan and loan commitments were largely offset by the release of certain loan-specific reserves. z Compensation and benefits increased by $15 million as a result of an increase in our employee headcount, compensation and one-time employee-related costs. General and administrative increased by $5 million due to additional investment in corporate infrastructure. z Income from equity method investments increased by $78 million, primarily due to new investments in our Portfolio, which had large one-time allocations of income under HLBV due to tax benefits recognized by our co-investors. z We recorded income tax expense of $17 million primarily due to the HLBV income described above, compared with an income tax benefit of $3 million in the previous year. Non-GAAP Financial measures We consider the following non-GAAP financial measures useful to investors as key supplemental measures of our performance: (1) distributable earnings, (2) distributable net investment income, and (3) managed assets. These non-GAAP financial measures should be considered along with, but not as alternatives to, net income or loss as measures of our operating performance. These non-GAAP financial measures, as calculated by us, may not be comparable to similarly named financial measures as reported by other companies that do not define such terms exactly as we define such terms. | 5 1 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7. mANAGemeNT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND ReSULTS OF OPeRATIONS PA R T I I Distributable earnings We calculate distributable earnings as GAAP net income (loss) excluding non-cash equity compensation expense, provisions for loss on receivables, amortization of intangibles, non-cash provision (benefit) for taxes, losses or (gains) from modification or extinguishment of debt facilities, any one- time acquisition related costs or non-cash tax charges and the earnings attributable to our non-controlling interest of our Operating Partnership. We also make an adjustment to our equity method investments in the renewable energy projects as described below. We will use judgment in determining when we will reflect the losses on receivables in our distributable earnings, and will consider certain circumstances such as the time period in default, sufficiency of collateral as well as the outcomes of any related litigation. In the future, distributable earnings may also exclude one-time events pursuant to changes in GAAP and certain other adjustments as approved by a majority of our independent directors. We believe a non-GAAP measure, such as distributable earnings, that adjusts for the items discussed above is and has been a meaningful indicator of our economic performance and is useful to our investors as well as management in evaluating our performance as it relates to expected dividend payments over time. As a REIT, we are required to distribute substantially all of our taxable income to investors in the form of dividends, which is a principal focus of our investors. Additionally, we believe that our investors also use distributable earnings, or a comparable supplemental performance measure, to evaluate and compare our performance to that of our peers, and as such, we believe that the disclosure of distributable earnings is useful to our investors. Certain of our equity method investments in renewable energy and energy efficiency projects are structured using typical partnership “flip” structures where the investors with cash distribution preferences receive a pre-negotiated return consisting of priority distributions from the project cash flows, in many cases, along with tax attributes. Once this preferred return is achieved, the partnership “flips” and the common equity investor, often the operator or sponsor of the project, receives more of the cash flows through its equity interests while the previously preferred investors retain an ongoing residual interest. We have made investments in both the preferred and common equity of these structures. Regardless of the nature of our equity interest, we typically negotiate the purchase prices of our equity investments, which have a finite expected life, based on our assessment of the expected cash flows we will receive from these projects discounted back to the net present value, based on a target investment rate, with the expected cash flows to be received in the future reflecting both a return on the capital (at the investment rate) and a return of the capital we have committed to the project. We use a similar approach in the underwriting of our receivables. Under GAAP, we account for these equity method investments utilizing the HLBV method. Under this method, we recognize income or loss based on the change in the amount each partner would receive, typically based on the negotiated profit and loss allocation, if the assets were liquidated at book value, after adjusting for any distributions or contributions made during such quarter. The HLBV allocations of income or loss may be impacted by the receipt of tax attributes, as tax equity investors are allocated losses in proportion to the tax benefits received, while the sponsors of the project are allocated gains of a similar amount. In addition, the agreed upon allocations of the project’s cash flows may differ materially from the profit and loss allocation used for the HLBV calculations. The cash distributions for those equity method investments where we apply HLBV are segregated into a return on and return of capital on our cash flow statement based on the cumulative income (loss) that has been allocated using the HLBV method. However, as a result of the application of the HLBV method, including the impact of tax allocations, the high levels of depreciation and other non-cash expenses that are common to renewable energy projects and the differences between the agreed upon profit and loss and the cash flow allocations, the distributions and thus the economic returns (i.e. return on capital) achieved from the investment are often significantly different from the income or loss that is allocated to us under the HLBV method. Thus, in calculating distributable earnings, for certain of these investments where there are characteristics as described above, we further adjust GAAP net income (loss) to take into account our calculation of the return on capital (based upon the underwritten investment rate) from our renewable energy equity method investments, as adjusted to reflect the performance of the project and the cash distributed. We believe this equity method investment adjustment to our GAAP net income (loss) in calculating our distributable earnings measure is an important supplement to the HLBV income allocations determined under GAAP for an investor to understand the economic performance of these investments where HLBV income can differ substantially from the economic returns. In 2021, we acquired equity investments in portfolios of renewable energy projects which have the majority of the distributions payable to more senior investors in the first few years of the project. The following table provides results related to our equity method investments for the last three years: (dollars in millions) Income (loss) under GAAP Distributable earnings Return of capital/(deferred cash collections) CASH COLLECTED Years ended December 31, 2021 2020 2019 $ $ $ 126 104 (51) 53 $ $ $ 48 55 102 157 $ $ $ 64 41 60 101 Distributable earnings does not represent cash generated from operating activities in accordance with GAAP and should not be considered as an alternative to net income (determined in accordance with GAAP), or an indication of our cash flow from operating activities (determined in accordance with GAAP), or a measure of our liquidity, or an indication of funds available to fund our cash needs, including our ability to make cash distributions. In addition, our methodology for calculating distributable earnings may differ from the methodologies employed by other companies to calculate the same or similar supplemental performance measures, and accordingly, our reported distributable earnings may not be comparable to similar metrics reported by other companies. 5 2 | HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7. mANAGemeNT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND ReSULTS OF OPeRATIONS PA R T I I We have calculated our distributable earnings for the years ended December 31, 2021, 2020 and 2019. The table below provides a reconciliation of our GAAP net income to distributable earnings: (dollars in thousands, except per share amounts) $ Per Share $ Per Share $ Per Share 2021 2020 2019 Years Ended December 31, Net income attributable to controlling stockholders(1) Distributable earnings adjustments $ 126,579 $ 1.51 $ 82,416 $ 1.10 $ 81,564 $ 1.24 Reverse GAAP income from equity method investments Add equity method investments earnings adjustment (126,421) 103,707 Non-cash equity-based compensation charges 17,047 Non-cash provision for loss on receivables Loss (gain) on debt modification or extinguishment Amortization of intangibles Non-cash provision (benefit) for taxes Current year earnings attributable to non- controlling interest 496 16,083 3,307 17,158 767 (47,963) (64,174) 55,305 16,791 10,096 — 3,291 (2,779) 343 41,437 14,160 8,027 — 3,285 8,091 356 DISTRIBUTABLE EARNINGS(2) $ 158,723 $ 1.88 $ 117,500 $ 1.55 $ 92,746 $ 1.40 (1) The per share data reflects the GAAP diluted earnings per share and is the most comparable GAAP measure to our distributable earnings per share. (2) Distributable earnings per share are based on 84,268,341 shares, 75,588,286 shares and 66,046,401 shares for the years ended December 31, 2021, 2020 and 2019, respectively, which represents the weighted average number of fully-diluted shares outstanding including our restricted stock awards, restricted stock units, long- term incentive plan units and the non-controlling interest in our Operating Partnership. We include any potential common stock issuance in this calculation related to our convertible notes using the treasury stock method and any potential common stock issuances related to share based compensation units in the amount we believe is reasonably certain to vest. To the extent a convertible note is converted during the period, we include its dilution using the treasury stock method until the date of conversion, after which we include the shares issued upon conversion. We believe the use of the treasury stock method is an appropriate representation of the potential dilution when considering the economic behaviors of the holders of the instrument. Distributable Net Investment Income We have a portfolio of investments in climate solutions that we finance using a combination of debt and equity. We calculate distributable net investment income as shown in the table below by adjusting GAAP-based net investment income for the equity method earnings adjustments which are applicable to distributable net investment income. We believe that this measure is useful to investors as it shows the recurring income generated by our Portfolio after the associated interest cost of debt financing. Our management also uses distributable net investment income in this way. Our non-GAAP distributable net investment income measure may not be comparable to similarly titled measures used by other companies. Also refer to discussion above related to Distributable Earnings. The following is a reconciliation of our GAAP-based net investment income to our distributable net investment income for the years ended December 31, 2021, 2020 and 2019: (in thousands) Interest income Rental income GAAP-based investment revenue Interest expense GAAP-based net investment income Equity method earnings adjustment Loss (gain) on debt modification or extinguishment Amortization of real estate intangibles Distributable net investment income $ $ $ $ Years Ended December 31, 2021 2020 2019 $ $ $ 106,889 25,905 132,794 121,705 11,089 103,707 16,083 3,089 95,559 $ 25,878 76,200 25,884 121,437 $ 102,084 92,182 29,255 $ 55,305 — 3,089 133,968 $ 87,649 $ 64,241 37,843 41,437 — 3,082 82,362 | 5 3 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7. mANAGemeNT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND ReSULTS OF OPeRATIONS PA R T I I managed Assets As we both consolidate assets on our balance sheet and securitize assets off-balance sheet, certain of our receivables and other assets are not reflected on our balance sheet where we may have a residual interest in the performance of the investment, such as servicing rights or a retained interest in cash flows. Thus, we present our investments on a non-GAAP “Managed Assets” basis, which assumes that securitized receivables are not sold. We believe that our Managed Asset information is useful to investors because it portrays the amount of both on- and off-balance sheet receivables that we manage, which enables investors to understand and evaluate the credit performance associated with our portfolio of receivables, investments and residual assets in off-balance sheet securitized receivables. Our management also uses Managed Assets in this way. Our non-GAAP Managed Assets measure may not be comparable to similarly titled measures used by other companies. The following is a reconciliation of our GAAP-based Portfolio to our Managed Assets as of December 31, 2021 and 2020: (dollars in millions) Equity method investments Commercial receivables, net of allowance Government receivables Receivables held-for-sale Real estate Investments GAAP-based Portfolio Assets held in securitization trusts Managed assets Other measures and metrics Portfolio Yield We calculate portfolio yield as the weighted average underwritten yield of the investments in our Portfolio as of the end of the period. Underwritten yield is the rate at which we discount the expected cash flows from the assets in our Portfolio to determine our purchase price. In calculating underwritten yield, we make certain assumptions, including the timing and amounts of cash flows generated by our investments, which may differ from actual results, and may update this yield to reflect our most current estimates of project performance. We believe that portfolio yield provides an additional metric to understand certain characteristics of our Portfolio as of a point in time. Our management uses portfolio yield this way and we believe that our investors use it in a similar fashion to evaluate certain characteristics of our Portfolio compared to our peers, and as such, we believe that the disclosure of portfolio yield is useful to our investors. Our Portfolio totaled approximately $3.6 billion as of December 31, 2021. Unlevered portfolio yield was 7.5% as of December 31, 2021 and 7.6% as of December 31, 2020. See Note 6 to our financial statements and MD&A - Our Business in this Form 10-K for additional discussion of the characteristics of our Portfolio as of December 31, 2021. Environmental Metrics As discussed in Item 1. Business, as part of our investment process, we calculate the estimated metric tons of CO2 equivalent emissions, or carbon emissions avoided by our investments by applying emissions factor data from the U.S. Government or the International Energy Administration to an estimate of a project’s energy production or As of December 31, 2021 2020 $ 1,760 $ 1,280 1,299 125 22 356 18 3,580 5,199 $ 8,779 $ 965 248 — 359 55 2,907 4,308 7,215 savings to compute an estimate of metric tons of carbon emissions avoided. We then determine the metric tons of carbon emissions avoided per thousand dollars of investments, in a calculation we refer to as CarbonCount, which enables us to measure the impact our investments have on reducing carbon emissions. We estimate that our investments originated in 2021 will reduce annual carbon emissions by approximately 0.8 million metric tons, equating to a CarbonCount of 0.50. In assessing our performance and results of operations, we also consider the impact of our operations on the environment. We utilize the carbon emissions categorizations established by the World Resources Institute Greenhouse Gas Protocol Corporate Standards (“Standards”) to set goals and calculate our estimated emissions. The categorizations are as follows: z Scope 1 GHG emissions – Direct emissions – Emissions from operations that are owned or controlled by the reporting company. Due to the nature of our operations, we do not have Scope 1 GHG emissions. z Scope 2 GHG emissions – Indirect emissions – Emissions from the generation of purchased or acquired energy such as electricity, steam, heating or cooling, consumed by the reporting company. As we purchase power for our offices from renewable, zero-carbon energy sources, we do not have market-based Scope 2 emissions. z Scope 3 GHG emissions – Indirect emissions – All other indirect emissions that occur in the value chain of the reporting company, including both upstream and downstream emissions. This includes the estimated emissions associated with employee commuting and business travel. 5 4 | HANNON ARMSTRONG | 2021 ANNUAL REPORT Item 7. mANAGemeNt’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDItION AND ReSULtS OF OPeRAtIONS PA R t I I The table below illustrates our goals and performance for 2021 in metric tons (“MT”).

The first year estimated carbon emissions avoided as a result of our investments originated in 2021 are 817 thousand MT. Human Capital Metrics As part of our broader human capital strategy, we monitor and disclose certain metrics which help us understand our workforce and our progress in fostering a diverse and inclusive work environment. As of December 31, 2021, we employed 97 people full-time, 2 person part-time, and 9 people as independent contractors. The average tenure of our employees as of December 31, 2021, was approximately 4.3 years, and more than 36% of our employees had been employed by us for more than 4 years. For the year ended December 31, 2021, we had an employee turnover rate of 3%, including one retirement. There were no retirements or resignations related to ill health. As discussed in Item 1. Business - Human Capital and Social Strategy, we are undertaking studies and are focused on continuing to increase the diversity of our workforce at all levels of our organization and are in the process of developing goals to enhance diversity and inclusion. These metrics are and will continue to be actively managed and will be reported along with the results of the studies to our executive leadership as well as our board of directors. Metrics surrounding the diversity and inclusion of our workforce are shown below: Percentage of various levels of the workforce who identify as male or female as of December 31, 2021 WORKFORCE 37% Female- Identifying 63% Male- Identifying MANAGERIAL ROLES 37% Female- Identifying 63% Male- Identifying 17% Female- Identifying LEADERSHIP TEAM 83% Male- Identifying 33% Female- Identifying BOARD OF DIRECTORS 67% Male- Identifying | 5 5 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7. mANAGemeNT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND ReSULTS OF OPeRATIONS PA R T I I Percentage of various levels of the workforce who identify as racial- or ethnic-minorities as of December 31, 2021 16% Black or African American 3% Hispanic or Latino 7% Asian 3% Two or More Races WORKFORCE 71% White 19% Black or African American MANAGERIAL ROLES 3% Hispanic or Latino 3% Asian 75% White LEADERSHIP TEAM 100% White Demographic data of promoted employees during the year ended December 31, 2021 32% Female- Identifying GENDER OF 2021 PROMOTEES 68% Male- Identifying 11% Black or African American BOARD OF DIRECTORS 89% White 11% Black or African- American 11% Hispanic or Latino 2021 PROMOTEES BY ETHNIC OR RACIAL SELF- IDENTIFICATION 78% White Of both our workforce and our managerial roles, 3% represent as LGBTQ.

We will use significant cash to make investments in climate solutions, repay principal and interest on our borrowings, make distributions to our stockholders and fund our operations. We use borrowings as part of our financing strategy to increase potential returns to our stockholders and have available to us a broad range of financing sources. We finance our investments primarily with non- recourse or recourse debt, equity and off-balance sheet securitization structures. We have adequate liquidity as of December 31, 2021, with unrestricted cash balances of $226 million, an unsecured revolving credit facility with an unused capacity of $350 million, and $25 million of available capacity in our secured revolving credit facilities. In 2021 we established our $100 million CarbonCount Green Commercial Paper Notes Program, offering us another potential short-term liquidity source, of which $50 million is available as of December 31, 2021. During 2021, we entered into a $400 million unsecured revolving credit facility which was upsized to $600 million in February 2022, we issued $201 million in equity, and issued $1 billion in senior unsecured notes, with $500 million of the proceeds of such issuance being used to redeem our 2024 senior unsecured notes. As of December 31, 2021, we had $440 million of non-recourse borrowings. We have $1.8 billion of senior unsecured notes and $152 million of convertible notes outstanding. $142 million of our 2022 senior convertible notes were converted into equity in 2021, representing a non-cash settlement of those notes. We also continue to utilize off-balance sheet securitization transactions, where we transfer the loans or other assets we originate to securitization trusts or other bankruptcy remote special purpose funding vehicles that are not consolidated on our balance sheet. We have continued to complete off-balance sheet securitization transactions with large institutional investors such as life insurance companies. As of December 31, 2021, the outstanding principal balance of our assets financed through the use of these off-balance sheet transactions was approximately $5.2 billion. In addition to general operational obligations, which are typically paid as incurred, and dividends, which are declared by our board of directors quarterly, we will have future cash needs related to the maturity of the non-amortizing balances of our Senior Unsecured Notes and the balances of our short-term commercial paper issuances and revolving credit facilities. We also have maturities related to our non- recourse debt and Senior Convertible Notes. However, as it relates to the non-recourse debt, to the extent there are not sufficient cash flows received from those investments pledged as collateral, the investor has no recourse against other corporate assets to recover any shortfalls and corporate cash contributions would not be required. As it relates to the Senior Convertible Notes, those obligations may be settled prior to maturity with the issuance of shares or a restructuring of the debt or at maturity with cash. For further information on our long-term debt, see Note 8 to our financial statements of this Form 10-K. The maturity profile of these obligations (excluding non-recourse debt) are shown below: Cash Maturities of Outstanding Debt $1,100 $1,000 $900 $800 $700 $600 $500 $400 $300 $200 $100 $— 2022 2023 2024 2025 2026 2027 2028 2029 2030 Senior Unsecured Notes Credit Facilities(1) Green Commercial Paper Notes (1) Our unsecured senior credit facility was amended in 2022 to have a maturity in 2025. We plan to raise additional equity capital and continue to use fixed and floating rate borrowings, which may be in the form of short-term commercial paper issuances, revolving credit facilities, recourse or non-recourse debt, repurchase agreements, and public and private debt issuances as a means of financing our business. We also expect to use both on-balance sheet and off-balance sheet securitizations. We may also consider the use of separately funded special purpose entities or funds to allow us to expand the investments that we make or to manage Portfolio diversification. The decision on how we finance specific assets or groups of assets is largely driven by risk and portfolio and financial management considerations, including the potential for gain on sale or fee income, as well as the overall interest rate environment, prevailing credit spreads and the terms of available financing and market conditions. During periods of market disruptions, certain sources of financing may be more readily accessible than others which may impact our financing decisions. Over time, as market conditions change, we may use other forms of debt and equity in addition to these financing arrangements. The amount of financial leverage we may deploy for particular assets will depend upon the availability of particular types of financing and our assessment of the credit, liquidity, price volatility and other risks of those assets, and the interest rate environment. As shown in the table below, our debt to equity ratio was approximately 1.6 to 1 as of December 31, 2021, which is below our current board-approved leverage limit of up to 2.5 to 1. Our percentage of fixed rate debt was approximately 96% as of December 31, 2021, which is within our targeted fixed rate debt percentage range of 75% to 100%. | 5 7 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7. mANAGemeNT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND ReSULTS OF OPeRATIONS PA R T I I The calculation of our fixed-rate debt and financial leverage as of December 31, 2021 and 2020 is shown in the chart below: (dollars in millions) Floating-rate borrowings Fixed-rate debt TOTAL DEBT(1) Equity Leverage December 31, 2021 % of Total December 31, 2020 % of Total $ $ $ 101 2,392 2,493 1,567 1.6 to 1 4% $ 96% 100% $ $ 23 2,166 2,189 1,210 1.8 to 1 1% 99% 100% (1) Floating-rate borrowings include borrowings under our floating-rate credit facilities. Debt excludes securitizations that are not consolidated on our balance sheet. We intend to use financial leverage for the primary purpose of financing our Portfolio and business activities and not for the purpose of speculating on changes in interest rates. While we may temporarily exceed the leverage limit, if our board of directors approves a material change to this limit, we anticipate advising our stockholders of this change through disclosure in our periodic reports and other filings under the Exchange Act. While we generally intend to hold our target assets that we do not securitize upon acquisition as long term investments, certain of our investments may be sold in order to manage our interest rate risk and liquidity needs, to meet other operating objectives and to adapt to market conditions. The timing and impact of future sales of receivables and investments, if any, cannot be predicted with any certainty. We believe our identified sources of liquidity will be adequate for purposes of meeting our short-term and long-term liquidity needs, which include funding future investments, debt service, operating costs and distributions to our stockholders. To qualify as a REIT, we must distribute annually at least 90% of our REIT’s taxable income without regard to the deduction for dividends paid and excluding net capital gains. These dividend requirements limit our ability to retain earnings and thereby increase the need to replenish capital for growth and our operations. Sources and Uses of Cash We had approximately $251 million and $310 million in unrestricted cash, cash equivalents, and restricted cash as of December 31, 2021 and 2020, respectively. Cash Flows Relating to Operating Activities Net cash provided by operating activities was approximately $13 million for the year ended December 31, 2021, driven primarily by net income of $127 million, less adjustments for non-cash and other items of $114 million. The non-cash and other adjustments consisted of decreases of $94 million related to equity method investments, $48 million related to non-cash gain on securitization, $22 million related to changes in receivables held for sale, and $7 million in accrued interest and other. These were partially offset by increases of $17 million for equity based compensation, $14 million of non-cash loss on debt extinguishment, $11 million of changes in accounts payable and accrued expenses, $11 million in amortization of financing costs, and $4 million of depreciation and amortization. Net cash provided by operating activities was approximately $73 million for the year ended December 31, 2020, driven primarily by net income of $83 million, less adjustments for non-cash and other items of $10 million. The non-cash and other adjustments consisted of increases of $3 million of depreciation and amortization, $8 million for amortization of finance costs, $17 million related to equity-based compensation, $13 million for equity method investments, $8 million related to accounts payable and accrued expenses, $14 million for gain on sale of receivables and investments, and $10 million for provision for loss on receivables. These increases were offset by $56 million related to non-cash gains on securitizations and $27 million related to other items. Cash Flows Relating to Investing Activities Net cash used in investing activities was approximately $703 million for the year ended December 31, 2021. We made equity method investments of $402 million, investments in receivables and fixed rate debt securities of $558 million, and funded escrow accounts of $12 million. These were offset by collected payments of $149 million from receivables and fixed rate debt securities and the receipt of $91 million from the sale of financial assets. We also collected $21 million from equity method investments in excess of income recognized to date under GAAP, withdrew $2 million from escrow accounts, and had other cash inflows of $6 million. Net cash used in investing activities was approximately $831 million for the year ended December 31, 2020. We made equity method investments of $886 million, investments in receivables and fixed rate debt securities of $296 million, and funded escrow accounts of $23 million. These were offset by collected payments of $135 million from receivables and fixed rate debt securities and the receipt of $128 million from the sale of financial assets. We also collected $99 million from equity method investments which are considered return of capital determined under GAAP, withdrew $8 million from escrow accounts, and had other cash inflows of $3 million. Cash Flows Relating to Financing Activities Net cash provided by financing activities was approximately $631 million for the year ended December 31, 2021. We received proceeds from the issuance of senior unsecured debt of $1 billion, net proceeds from common stock issuances of $201 million, and proceeds from credit facilities and commercial paper notes of $150 million. These were partially offset by the redemption of senior unsecured notes of $514 million, principal payments on credit facilities of $22 million, principal payments on non-recourse debt of $38 million, payments of $14 million for withholding requirements as a result of the vesting of employee shares, payment of debt issuance costs of $18 million and payments of dividends, distributions, and other financing activities of $114 million. 5 8 | HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7. mANAGemeNT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND ReSULTS OF OPeRATIONS PA R T I I Net cash provided by financing activities was approximately $962 million for the year ended December 31, 2020. We received proceeds from the issuance of senior unsecured debt of $771 million, net proceeds from common stock issuances of $298 million, proceeds from the issuance of convertible notes of $144 million, proceeds from credit facilities of $126 million, and proceeds from non-recourse debt of $16 million.

Off-Balance Sheet Arrangements We have relationships with non-consolidated entities or financial partnerships, such as entities often referred to as structured investment vehicles, or special purpose or variable interest entities, established to facilitate the sale of securitized assets. Other than our securitization assets (including any outstanding servicer advances) of approximately $210 million as of December 31, 2021, that may be at risk in the event of defaults or prepayments in our securitization trusts and as discussed below, and except as disclosed in Note 9 to our audited financial statements in this Form 10-K, we have not guaranteed any obligations of non-consolidated entities or entered into any commitment or intent to provide additional funding to any such entities. A more detailed description of our relations with non-consolidated entities can be found in Note 2 of our audited financial statements in this Form 10-K. Dividends U.S. federal income tax law generally requires that a REIT distribute annually at least 90% of its REIT taxable income, without regard to the deduction for dividends paid and excluding net capital gains, and that it pays tax at regular corporate rates to the extent that it annually distributes less than 100% of its REIT taxable income. Our current policy is to pay quarterly distributions, which on an annual basis will equal or exceed substantially all of our REIT taxable income. The taxable income of the REIT can vary from our GAAP earnings due to a number of different factors, including the book to tax timing differences of income and expense recognition from our transactions as well as the amount of taxable income of our TRS distributed to the REIT. See Note 10 to our financial statements in this Form 10-K regarding the amount of our distributions that are treated as ordinary taxable income to our stockholders. Any distributions we make will be at the discretion of our board of directors and will depend upon, among other things, our actual results of operations. These results and our ability to pay distributions will be affected by various factors, including the net interest and other income from our assets, our operating expenses and any other expenditures. In the event that our board of directors determines to make distributions in excess of the income or cash flow generated from our assets, we may make such distributions from the proceeds of future offerings of equity or debt securities or other forms of debt financing or the sale of assets. To the extent, that in respect of any calendar year, cash available for distribution is less than our taxable income, or our declared distribution we could be required to sell assets, borrow funds or raise additional Book Value Considerations As of December 31, 2021, we carried only our investments and residual assets in securitized financial assets at fair value on our balance sheet. As a result, in reviewing our book value, there are a number of important factors and limitations to consider. Other than our In connection with some of our transactions, we have provided certain limited guarantees to other transaction participants covering the accuracy of certain limited representations, warranties or covenants and provided an indemnity against certain losses from “bad acts” including fraud, failure to disclose a material fact, theft, misappropriation, voluntary bankruptcy or unauthorized transfers. In some transactions, we have also guaranteed our compliance with certain tax matters, such as negatively impacting the investment tax credit and certain other obligations in the event of a change in ownership or our exercising certain protective rights. capital to make cash distributions or make a portion of the required distribution in the form of a taxable stock distribution or distribution of debt securities. We will generally not be required to make distributions with respect to activities conducted through our domestic TRS. To the extent that we generate taxable income, distributions to our stockholders generally will be taxable as ordinary income, although all or a portion of such distributions may be designated by us as a qualified dividend or capital gain. Beginning in 2018 (and through taxable years ending in 2025), a deduction is permitted for certain pass-through business income, including “qualified REIT dividends” (generally, dividends received by a REIT shareholder that are not designated as capital gain dividends or qualified dividend income), which will allow U.S. individuals, trusts and estates to deduct up to 20% of such amounts, subject to certain limitations, resulting in an effective maximum U.S. federal income tax rate of 29.6% on such qualified REIT dividends. In the event we make distributions to our stockholders in excess of our taxable income, the excess will constitute a return of capital. In addition, a portion of such distributions may be taxable stock dividends payable in our shares. We will furnish annually to each of our stockholders a statement setting forth distributions paid during the preceding year and their characterization as ordinary income, return of capital, qualified dividend income or capital gain. The dividends declared in 2021 and 2020 are described in Note 11 to our audited financial statements in this Form 10-K. investments and the residual assets in securitized financial assets that are carried on our balance sheet at fair value as of December 31, 2021, the carrying value of our remaining assets and liabilities are calculated as of a particular point in time, which is largely determined | 5 9 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7A. QUANTITATIVe AND QUALITATIVe DISCLOSUReS ABOUT mARKeT RISK PA R T I I at the time such assets and liabilities were added to our balance sheet using a cost basis in accordance with GAAP. Other than the allowance for current expected credit losses applied to our commercial and government receivables, our remaining assets and liabilities do not incorporate other factors that may have a significant impact on their value, most notably any impact of business activities, changes in estimates, or changes in general economic conditions, interest rates or commodity prices since the dates the assets or liabilities were initially recorded. Accordingly, our book value does not necessarily represent an estimate of our net realizable value, liquidation value or our market value. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK We anticipate that our primary market risks will be related to the credit quality of our counterparties and project companies, market interest rates, the liquidity of our assets, commodity prices and environmental factors. We will seek to manage these risks while, at the same time, seeking to provide an opportunity to stockholders to realize attractive returns through ownership of our common stock. Many of these risks have been magnified due to the continuing economic disruptions caused by the COVID-19 pandemic; however, while we continue to monitor the pandemic its impact on such risks remains uncertain and difficult to predict. Credit Risks We source and identify quality opportunities within our broad areas of expertise and apply our rigorous underwriting processes to our transactions, which, we believe, will generally enable us to minimize our credit losses and maintain access to attractive financing. In the case of various renewable energy and other sustainable infrastructure projects, we will be exposed to the credit risk of the obligor of the project’s PPA or other long-term contractual revenue commitments, as well as to the credit risk of certain suppliers and project operators. While we do not anticipate facing significant credit risk in our assets related to government energy efficiency projects, we are subject to varying degrees of credit risk in these projects in relation to guarantees provided by ESCOs where payments under energy savings performance contracts are contingent upon achieving pre- determined levels of energy savings. We are exposed to credit risk in our other projects that do not benefit from governments as the obligor such as on balance sheet financing of projects undertaken by universities, schools and hospitals, as well as privately owned commercial projects. We have invested in mezzanine loans and, as a result, we are exposed to additional credit risk. We seek to manage credit risk through thorough due diligence and underwriting processes, strong structural protections in our transaction agreements with customers and continual, active asset management and portfolio Interest Rate and Borrowing Risks Interest rate risk is highly sensitive to many factors, including governmental monetary and tax policies, domestic and international economic and political considerations and other factors beyond our control. We are subject to interest rate risk in connection with new asset originations and our borrowings, including our credit facilities, and in the future, any new floating rate assets, credit facilities or other borrowings. Because short-term borrowings are generally short-term commitments of capital, lenders may respond to market conditions, making it more difficult for us to secure continued financing. If we are not able to renew our then existing borrowings or arrange for new financing on terms acceptable to us, or if we default on our covenants or are otherwise unable to access funds under any of these borrowings, we may have to curtail our origination of new assets and/or dispose of assets. We face particular risk in this regard given that we expect many of our borrowings will have a shorter duration 6 0 | monitoring. Nevertheless, unanticipated credit losses could occur and during periods of economic downturn in the global economy, our exposure to credit risks from obligors increases, and our efforts to monitor and mitigate the associated risks may not be effective in reducing our credit risks. We utilize a risk rating system to evaluate projects that we target. We first evaluate the credit rating of the obligors involved in the project using an average of the external credit ratings for an obligor, if available, or an estimated internal rating based on a third-party credit scoring system. We then estimate the probability of default and estimated recovery rate based on the obligors’ credit ratings and the terms of the contract. We also review the performance of each investment, including through, as appropriate, a review of project performance, monthly payment activity and active compliance monitoring, regular communications with project management and, as applicable, its obligors, sponsors and owners, monitoring the financial performance of the collateral, periodic property visits and monitoring cash management and reserve accounts. The results of our reviews are used to update the project’s risk rating as necessary. Additional detail of the credit risks surrounding our Portfolio can be found in Note 6 to our financial statements in this Form 10-K. than the assets they finance. Increasing interest rates may reduce the demand for our investments while declining interest rates may increase the demand. Both our current and future revolving credit facilities and other borrowings may be of limited duration and are periodically refinanced at then current market rates. We attempt to reduce interest rate risks and to minimize exposure to interest rate fluctuations through the use of fixed rate financing structures, when appropriate, whereby we seek to (1) match the maturities of our debt obligations with the maturities of our assets, (2) borrow at fixed rates for a period of time or (3) match the interest rates on our assets with like-kind debt (i.e., we may finance floating rate assets with floating rate debt and fixed-rate assets with fixed-rate debt), directly or through the use of interest rate swap agreements, interest rate cap agreements or other financial instruments, or through a combination of these strategies. We expect these instruments will allow us to minimize, but not eliminate, the risk that we must refinance our liabilities before the maturities of our assets and to reduce the impact of changing interest rates on our earnings. HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7A. QUANTITATIVe AND QUALITATIVe DISCLOSUReS ABOUT mARKeT RISK PA R T I I In addition to the use of traditional derivative instruments, we also seek to mitigate interest rate risk by using securitizations, syndications and other techniques to construct a portfolio with a staggered maturity profile. We monitor the impact of interest rate changes on the market for new originations and often have the flexibility to negotiate the term of our investments to offset interest rate increases. Typically, our long-term debt is at fixed rates or we may at times use interest rate hedges that convert most of the floating rate debt to fixed rate debt. If interest rates rise, and our fixed rate debt balance remains constant, we expect the fair value of our fixed rate debt to decrease and the value of our hedges on floating rate debt to increase. See Note 3 to our audited financial statements in this Form 10-K for the estimated fair value of our fixed rate long-term debt, which is based on having the same debt service requirements that could have been borrowed at the date presented, at prevailing current market interest rates. Our revolving credit facilities are variable rate lines of credit with approximately $100 million outstanding as of December 31, 2021. Increases in interest rates would result in higher interest expense while Liquidity and Concentration Risk The assets that comprise our Portfolio are not and are not expected to be publicly traded. A portion of these assets may be subject to legal and other restrictions on resale or will otherwise be less liquid than publicly-traded securities. The illiquidity of our assets may make it difficult for us to sell such assets if the need or desire arises, including in response to changes in economic and other conditions. Certain of the projects in which we invest have one obligor and thus we are Commodity Price Risk When we make equity or debt investments for a renewable energy project that acts as a substitute for an underlying commodity, we may be exposed to volatility in prices for that commodity. The performance of renewable energy projects that produce electricity can be impacted by volatility in the market prices of various forms of energy, including electricity, coal and natural gas. This is especially true for GC utility scale projects that sell power on a wholesale basis as opposed to BTM projects which compete against the retail or delivered costs of electricity which includes the cost of transmitting and distributing the electricity to the end user. Although we generally focus on renewable energy projects that have the majority of their operating cash flow supported by long-term PPAs or leases, many of our projects have shorter term contracts (which may have the potential of producing higher current returns) or sell their power in the open market on a merchant basis. The cash flows of such projects, and thus the repayment of, or the returns available for, our assets, are subject to risk if energy prices change. We also attempt to mitigate our exposure through structural protections. These structural protections, which are typically in the form of a preferred return mechanism, are designed to allow recovery of our capital and an acceptable return over time. When structuring and underwriting these transactions, we evaluate these transactions using a variety of decreases in interest rates would result in lower interest expense. As described above, we may use various financing techniques including interest rate swap agreements, interest rate cap agreements or other financial instruments, or a combination of these strategies to mitigate the variable interest nature of these facilities. A 50 basis point increase in LIBOR would increase the quarterly interest expense related to the $101 million in variable rate borrowings by $126 thousand. Such hypothetical impact of interest rates on our variable rate borrowings does not consider the effect of any change in overall economic activity that could occur in a rising interest rate environment. Further, in the event of such a change in interest rates, we may take actions to further mitigate our exposure to such a change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, the analysis assumes no changes in our financial structure. We record certain of our assets at fair value in our financial statements and any changes in the discount rate would impact the value of these assets. See Note 3 to our audited financial statements in this Form 10-K. subject to concentration risk for these investments and could incur significant losses if any of these projects perform poorly or if we are required to write down the value of any of these projects. Many of our assets, or the collateral supporting those assets, are concentrated in certain geographic areas, which may make those assets or the related collateral more susceptible to natural disasters or other regional events. See also “Credit Risks” discussed above. scenarios, including natural gas prices remaining low for an extended period of time. Despite these protections, as natural gas price volatility continues or PPAs expire, the cash flows from certain of our projects are exposed to these market conditions and we work with the projects sponsors to minimize any impact as part of our on-going active asset management and portfolio monitoring. In the case of utility scale solar projects, we focus on owning the land under the project where our rent is paid out of project operational costs before the debt or equity in the project receives any payments. Certain of the projects in which we invest may also be obligated to physically deliver energy under PPAs or related agreements, and to the extent they are unable to do so may be negatively impacted. We believe that low prices in natural gas will increase demand for some types of our projects, such as combined heat and power, but may reduce the demand for other projects such as renewable energy that may be a substitute for natural gas. We seek to structure our energy efficiency investments so that we typically avoid exposure to commodity price risk. However, volatility in energy prices may cause building owners and other parties to be reluctant to commit to projects for which repayment is based upon a fixed monetary value for energy savings that would not decline if the price of energy declines. | 6 1 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITem 7A. QUANTITATIVe AND QUALITATIVe DISCLOSUReS ABOUT mARKeT RISK PA R T I I Environmental Risks Our business is impacted by the effects of climate change and various related regulatory responses. We discuss the risks and opportunities associated with the impacts of climate change in Item 7. Management’s Discussion and Analysis of Financial Condition Risk Management Our ongoing active asset management and portfolio monitoring processes provide investment oversight and valuable insight into our origination, underwriting and structuring processes. These processes create value through active monitoring of the state of our markets, enforcement of existing contracts and asset management. As described above, we engage in a variety of interest rate management techniques that seek to mitigate the economic effect of interest rate changes on the values of, and returns on, some of our assets. While we have either written off or specifically identified only two transactions, amounting to approximately $19 million (net of recoveries) on the approximately $8 billion of debt and real estate transactions we originated since 2012, which represents an aggregate loss of approximately 0.2% on cumulative transactions originated over this time period, there can be no assurance that we will continue to be as successful, particularly as we invest in more credit sensitive assets or more equity investments and engage in increasing numbers of transactions with obligors other than U.S. federal government agencies. We seek to manage credit risk using thorough due diligence and underwriting processes, strong structural protections in our and Results of Operations - Impact of climate change on our future operations. This discussion outlines potential qualitative impacts to our business, quantitative illustrations of sensitivity as well as our strategy and resilience to these risks and opportunities. agreements with customers and continual, active asset management and portfolio monitoring. Additionally, we have a Finance and Risk Committee of our board of directors which discusses and reviews policies and guidelines with respect to our risk assessment and risk management for various risks, including, but not limited to, our interest rate, counter party, credit, capital availability, and refinancing risks. As it relates to environmental risks, when we underwrite and structure our investments the environmental risks and opportunities are an integral consideration to our investment parameters. While we cannot fully protect our investments, we seek to mitigate these risks by using third party experts to conduct engineering and weather analysis and insurance reviews as appropriate. Weather related risks are at times managed in cooperation with our clients where they buy offsetting power positions to mitigate power market disruptions or operational impacts. Once a transaction has closed we continue to monitor the environmental risks to the Portfolio. We further discuss our strategy to managing these risks in Item 7.

Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of Hannon Armstrong Sustainable Infrastructure Capital, Inc. (the Company) as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive income, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021, and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with U.S. generally accepted accounting principles. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 22, 2022 expressed an unqualified opinion thereon. Adoption of ASU 2016-13 As discussed in Note 2 to the consolidated financial statements, the Company changed its method of accounting for credit losses in 2020 due to the adoption of Accounting Standards Update (ASU) No. 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and the related amendments. Basis for Opinion These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the 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 audit to obtain reasonable assurance about whether the financial statements Critical Audit Matter The critical audit matter communicated below is a matter arising from the current period audit of the 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 financial statements and (2) involved our especially challenging, subjective or are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion. complex judgments. The communication of the 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 a separate opinion on the critical audit matter or on the account or disclosure to which it relates. 6 4 | HANNON ARMSTRONG | 2021 ANNUAL REPORT ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA PA R T I I Accounting for Equity Investments in Renewable Energy and Energy Efficiency Projects Description of the Matter As discussed in Note 2 to the consolidated financial statements, the Company makes equity investments in renewable energy and energy efficiency projects that are accounted for under the equity method of accounting. During the year ended December 31, 2021, the Company made new equity investments in renewable energy and energy efficiency projects amounting to $401.9 million and held $1.8 billion of equity investments in renewable energy and energy efficiency projects as of December 31, 2021. The Company’s determination that it does not have the power to direct the significant activities impacting each of the investees’ economic performance (“power”) is critical to its determination that it is not the primary beneficiary of the investee. Also, as described in Note 2 to the consolidated financial statements, for equity method investments that contain preferences with regard to cash flows from operations, capital events and liquidation in their respective limited liability company agreements (“LLC Agreements”), the Company applies the Hypothetical Liquidation at Book Value (“HLBV”) method to record its share of profits and losses on these investments, which is done one quarter in arrears to allow for receipt of financial information from its investees. How We Addressed the Matter in our Audit Auditing the Company’s determination of whether it has power was complex and required significant judgment to determine both the activities of the investee that most significantly impact the investee’s economics, and the distribution of the power among the members of the investee that ultimately determine the outcome of such activities. In addition, auditing the Company’s application of the HLBV method was challenging and inherently complex, because the application is based on its interpretations of the liquidation provisions outlined within investees’ LLC Agreements. We tested controls that address the risks of material misstatement relating to: i) the determination of whether the Company has the power to direct the significant activities of the investees and ii) the recognition of its share of investees’ profits and losses through use of the HLBV method based on financial information reported to the Company from its investees. For example, we tested controls over management’s review of the variable interest model and determination of whether the Company has power. We also tested controls over management’s review of the HLBV method, including the application of the liquidation provisions and the financial information reported from their investees. To evaluate whether the Company has power over each investee, our audit procedures included, among others, inspecting LLC Agreements and evaluating management’s analysis of the significant activities of the investee and which parties can direct those significant activities. For example, as part of our evaluation, we considered the purpose and design of the investee and the legal rights of each of the involved parties, including the significance of the decisions that each party makes. We also tested the rights of each party included in management’s analysis by comparing such rights to the LLC Agreements. We tested the Company’s application of the HLBV method for a sample of both new and existing investments. Our audit procedures included, among others, involving tax professionals to assist in evaluating the Company’s application of the liquidation provisions within the LLC Agreements. Specifically, we assessed the Company’s HLBV calculations by agreeing provisions of the calculations, such as the application of stated preferred returns and allocation of tax attributes, to the terms of the LLC Agreements for each of these investments. We also performed additional procedures on the Company’s HLBV calculations that included, but were not limited to, recalculating the stated preferred returns, recalculating allocations of tax attributes, comparing inputs included within the calculations to the information reported to the Company by its investee, and recalculating the Company’s share of profits and losses of the investee. /s/ Ernst & Young LLP We have served as the Company’s auditor since 1983.

FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA PA R T I I REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Stockholders and the Board of Directors of Hannon Armstrong Sustainable Infrastructure Capital, Inc. Opinion on Internal Control Over Financial Reporting We have audited Hannon Armstrong Sustainable Infrastructure Capital, Inc.’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Hannon Armstrong Sustainable Infrastructure Capital, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive income, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2021, and the related notes and our report dated February 22, 2022 expressed an unqualified opinion thereon. Basis for Opinion The Company’s management is responsible 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 Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. 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. /s/ Ernst & Young LLP Tysons, Virginia February 22, 2022 6 6 | HANNON ARMSTRONG | 2021 ANNUAL REPORT ITEM 8.

FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA PA R T I I Hannon Armstrong Sustainable Infrastructure Capital, Inc. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS December 31, 2021 The Company 1. Hannon Armstrong Sustainable Infrastructure Capital, Inc. (the “Company”) invests in climate solutions by providing capital to leading companies in the energy efficiency, renewable energy and other sustainable infrastructure markets. Our goal is to generate attractive returns from a diversified portfolio of projects with long-term and predictable cash flows from proven technologies that reduce carbon emissions or increase resilience to climate change. The Company and its subsidiaries are hereafter referred to as “we,” “us” or “our.” Our investments take various forms, including equity, joint ventures, real estate ownership, or lending or other financing transactions, and typically benefit from contractually committed high credit quality obligors. We also generate on-going fees through off- balance sheet securitization transactions, advisory services and asset management. We refer to the income producing assets that we hold on our balance sheet as our “Portfolio.” Our Portfolio may include: z equity investments in either preferred or common structures in unconsolidated entities which own renewable energy or energy efficiency projects; z commercial and government receivables, such as loans for renewable energy and energy efficiency projects; z real estate, such as land or other assets leased for use by climate solutions projects typically under long-term leases; and z investments in debt securities of renewable energy or energy efficiency projects. We finance our business through cash on hand, borrowings through short-term commercial paper issuances and revolving credit facilities, issuances of unsecured debt, asset-backed securitization transactions and equity issuances. We also generate fee income through securitizations and syndications, by providing broker/dealer services and by managing and servicing assets owned by third parties. Our common stock is listed on the New York Stock Exchange (“NYSE”) under the symbol “HASI.” We have qualified as a real estate investment trust (“REIT”) and also intend to continue to operate our business in a manner that will maintain our exemption from registration as an investment company under the Investment Company Act of 1940 (the “1940 Act”), as amended. We operate our business through, and serve as the sole general partner of, our operating partnership subsidiary, Hannon Armstrong Sustainable Infrastructure, L.P., (the “Operating Partnership”), which was formed to acquire and directly or indirectly own our assets. 2. Summary of Significant Accounting Policies Basis of Presentation Consolidation The preparation of financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates and such differences could be material. In the opinion of management, all adjustments necessary to present fairly our financial position, results of operations and cash flows have been included. Certain amounts in the prior years have been reclassified to conform to the current year presentation. The consolidated financial statements include our accounts and controlled subsidiaries, including the Operating Partnership. All material intercompany transactions and balances have been eliminated in consolidation. We account for our investments in entities that are considered voting interest entities or variable interest entities (“VIEs”) under ASC 810 and assess whether we should consolidate these entities on an ongoing basis. We have established various special purpose entities or securitization trusts for the purpose of securitizing certain assets that are not consolidated in our financial statements as described below in Securitization of Financial Assets. Since we have assessed that we have power over and receive the benefits from those special purpose entities that are formed for the purpose of holding our assets on our balance sheet, we have concluded we are the primary beneficiary and should consolidate these entities under the provisions of ASC 810. We also have certain subsidiaries we deem to be voting interest entities that we control through our ownership of voting interests and accordingly consolidate. Following the guidance for non-controlling interests in Financial Accounting Standards Board Accounting Standards Codification (“ASC”) 810, Consolidation (“ASC 810:), references in this report to our earnings per share and our net income and stockholders’ equity attributable to common stockholders do not include amounts attributable to non-controlling interests. Certain of our equity method investments were determined to be interests in VIEs in which we are not the primary beneficiary, as we do not direct the significant activities of these entities, and thus we account for those investments as Equity Method Investments as discussed below. Our maximum exposure to loss through these investments is limited to their recorded values. However, we may provide financial | 7 3 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA PA R T I I commitments to these VIEs or guarantees of certain of their obligations. Certain other entities in which we have equity investments have been assessed to be voting interest entities and are not consolidated as we exert significant influence rather than control through our ownership of voting interests, and accordingly we account for them as equity method investments described below. Equity Method Investments We have made equity investments in various renewable energy and energy efficiency projects. These investments are typically owned in holding companies (using limited liability companies (“LLCs”) taxed as partnerships) where we partner with either the operator of the project or other institutional investors. We share in the cash flows, income, and tax attributes according to a negotiated schedule which typically does not correspond with our ownership percentages. Investors, if any, in a preferred return position typically receive a priority distribution of all or a portion of the project’s cash flows, and in some cases, tax attributes. Once the preferred return, if applicable, is achieved, the partnership “flips” and the operator of the project along with any other common equity investors receive a larger portion of the cash flows, with the previously preferred investors retaining an on-going residual interest. Our equity investments in renewable energy or energy efficiency projects are accounted for under the equity method of accounting. Under the equity method of accounting, the carrying value of these equity method investments is determined based on amounts we invested, adjusted for the equity in earnings or losses of the investee allocated based on the LLC agreement, less distributions received. For the LLC agreements that contain preferences with regard to cash flows from operations, capital events and liquidation, we reflect our share of profits and losses by determining the difference between our claim on the investee’s reported book value at the beginning and the end of the period, which is adjusted for distributions received and contributions made. This claim is calculated as the amount we would receive if the investee were to liquidate all of its assets at the recorded amounts determined in accordance with GAAP and distribute the resulting cash to creditors and investors in accordance with their respective priorities. This method is referred to as the hypothetical liquidation at book value method (“HLBV”). Our exposure to loss to these investments is limited to the amount of our equity investment, as well as other investments we may have in the same investee. Any difference between the amount of our investment and the amount of underlying equity in net assets is generally amortized over the life of the assets and liabilities to which the difference relates. Cash distributions received from each equity method investment are classified as operating activities to the extent of cumulative earnings for each investment in our consolidated statements of cash flows. Our initial investment and additional cash distributions beyond that which are classified as operating activities are classified as investing activities in our consolidated statements of cash flows. We typically recognize earnings one quarter in arrears for certain of these investments to allow for the receipt of financial information. We evaluate on a quarterly basis whether our investments accounted for using the equity method have an other than temporary impairment (“OTTI”). An OTTI occurs when the estimated fair value of an investment is below the carrying value and the difference is determined to not be recoverable. This evaluation requires significant judgment regarding, but not limited to, the severity and duration of the impairment; the ability and intent to hold the securities until recovery; financial condition, liquidity, and near-term prospects of the issuer; specific events; and other factors. Commercial and Government Receivables Commercial and government receivables (“receivables”) include project loans and receivables. These receivables are separately presented in our balance sheet to illustrate the differing nature of the credit risk related to these assets. Unless otherwise noted, we generally have the ability and intent to hold our receivables for the foreseeable future and thus they are classified as held for investment. Our ability and intent to hold certain receivables may change from time to time depending on a number of factors including economic, liquidity and capital market conditions. At inception of the arrangement, the carrying value of receivables held for investment represents the present value of the note, lease or other payments, net of any unearned fee income, which is recognized as income over the term of the note or lease using the effective interest method. Receivables that are held for investment are carried at amortized cost, net of any unamortized acquisition premiums or discounts and include origination and acquisition costs, as applicable. Our initial investment and principal repayments of these receivables are classified as investing activities and the interest collected is classified as operating activities in our consolidated statements of cash flows. Receivables that we intend to sell in the short-term are classified as held-for-sale and are carried at the lower of amortized cost or fair value on our balance sheet, which is assessed on an individual asset basis. The purchases and proceeds from receivables that we intend to sell at origination are classified as operating activities in our consolidated statements of cash flows. Interest collected is classified as an operating activity in our consolidated statements of cash flows. Certain of our receivables may include the ability to defer required interest payments in exchange for increasing the receivable balance at the borrower’s option. We generally accrue this paid-in-kind (“PIK”) interest when collection is expected, and cease accruing PIK interest if there is insufficient value to support the accrual or we expect that any portion of the principal or interest due is not collectible. We evaluate our receivables for an allowance as determined under ASC Topic 326 Financial Instruments- Credit Losses (“Topic 326”) and for our internally derived asset performance categories included in Note 6 to our financial statements on at least a quarterly basis and more frequently when economic or other conditions warrant such an evaluation. When a receivable becomes 90 days or more past due, and if we otherwise do not expect the debtor to be able to service all of its debt or other obligations, we will generally consider the receivable delinquent or impaired and place the receivable on non- accrual status and cease recognizing income from that receivable until the borrower has demonstrated the ability and intent to pay contractual amounts due. If a receivable’s status significantly improves regarding the debtor’s ability to service the debt or other obligations, we will remove it from non-accrual status. We determine our allowance based on the current expectation of credit losses over the contractual life of our receivables as required by Topic 326, which we adopted in the year ended December 31, 2020. We use a variety of methods in developing our allowance including discounted cash flow analysis and probability-of-default/ loss given default (“PD/LGD”) methods. In developing our estimates, we consider our historical experience with our and similar assets in addition to our view of both current conditions and what we expect to occur within a period of time for which we can develop reasonable and supportable forecasts, typically two years. For periods following the reasonable and supportable forecast period, we revert to historical information when developing assumptions used in our estimates. In 7 4 | HANNON ARMSTRONG | 2021 ANNUAL REPORT ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA PA R T I I developing our forecasts, we consider a number of qualitative and quantitative factors in our assessment, including a project’s operating results, loan-to-value ratio, any cash reserves, the ability of expected cash from operations to cover the cash flow requirements currently and into the future, key terms of the transaction, the ability of the borrower to refinance the transaction, other credit support from the sponsor or guarantor and the project’s collateral value. In addition, we consider the overall economic environment, the climate solutions sector, the effect of local, industry, and broader economic factors such as unemployment rates and power prices, the impact of any variation in weather and the historical and anticipated trends in interest rates, defaults and loss severities for similar transactions. For those assets where we record our allowance using a discounted cash flow method, we have elected to record the change in allowance due solely to the passage of time through the provision for loss on receivables in our income statement. For assets where the obligor is a publicly rated entity, we consider the published historical performance of entities with similar ratings in developing our estimate of an allowance, making adjustments determined by management to be appropriate during the reasonable and supportable forecast period. We have made certain loan commitments that are within the scope of Topic 326. When estimating an allowance for these loan commitments we consider the probability of certain amounts to be funded and apply either a discounted cash flow or PD/LGD methodology as described above. We charge off receivables against the allowance, if any, when we determine the unpaid principal balance is uncollectible, net of recovered amounts. Any provision we record for an allowance is a non-cash reconciling item to cash from operating activities in our consolidated statements of cash flows. Real Estate Real estate consists of land or other real property and its related lease intangibles, net of any amortization. Our real estate is generally leased to tenants on a triple net lease basis, whereby the tenant is responsible for all operating expenses relating to the property, generally including property taxes, insurance, maintenance, repairs and capital expenditures. Certain real estate transactions may be characterized as “failed sale-leaseback” transactions as defined under ASC Topic 842, Leases, and thus are accounted for similarly to our commercial receivables as described above in Government and Commercial Receivables. For our other real estate lease transactions that are classified as operating leases, the scheduled rental revenue typically varies during the lease term and thus rental income is recognized on a straight-line basis, unless there is considerable risk as to collectability, so as to produce a constant periodic rent over the term of the lease. Accrued rental income is the aggregate difference between the scheduled rents that vary during the lease term and the income recognized on a straight-line basis and is recorded in other assets. Expenses, if any, related to the ongoing operation of leases where we are the lessor are charged to operations as incurred. Our initial investment is classified as investing activities and income collected for rental income is classified as operating activities in our consolidated statements of cash flows. When our real estate transactions are treated as an asset acquisition with an operating lease, we typically record our real estate purchases at cost, including acquisition and closing costs, which is allocated to each tangible and intangible asset acquired on a relative fair value basis. The fair value of the tangible assets of an acquired leased property is determined by valuing the property as if it were vacant, and the “as-if-vacant” value is then allocated to land, building and tenant improvements, if any, based on the determination of the fair values of these assets. The as-if-vacant fair value of a property is typically determined by management based on appraisals by a qualified appraiser. In determining the fair value of the identified intangibles of an acquired property, above-market and below-market in-place lease values are valued based on the present value (using an interest rate that reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases, and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining term of the lease, including renewal periods reasonably certain of being exercised by the lessee. The capitalized off-market lease values are amortized as an adjustment of rental income over the term used to value the intangible. We also record, as appropriate, an intangible asset for in-place leases. The value of the leases in place at the time of the transaction is equal to the potential income lost if the leases were not in place. The amortization of this intangible occurs over the initial term unless management believes that it is reasonably certain that the tenant would exercise the renewal option, in which case the amortization would extend through the renewal period. If a lease were to be terminated, all unamortized amounts relating to that lease would be written off. Investments Investments are debt securities that meet the criteria of ASC 320, Investments-Debt and Equity Securities. We have designated our debt securities as available-for-sale and carry these securities at fair value on our balance sheet. Unrealized gains and losses, to the extent not considered to be credit related, on available-for-sale debt securities are recorded as a component of accumulated other comprehensive income (“AOCI”) in equity on our balance sheet. When a security is sold, we reclassify the AOCI to earnings based on specific identification. Our initial investment and principal repayments of these investments are classified as investing activities and the interest collected is classified as operating activities in our consolidated statements of cash flows. We evaluate our investments for impairment on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. Our impairment assessment is a subjective process requiring the use of judgments and assumptions. Accordingly, we regularly evaluate the extent and impact of any credit deterioration associated with the financial and operating performance and value of the underlying project. We consider several qualitative and quantitative factors in our assessment. The primary factor in our assessment is the current fair value of the security, while other factors include changes in the credit rating, performance of the underlying project, key terms of the transaction, the value of any collateral and any support provided by the sponsor or guarantor. To the extent that we have identified an impairment for a security, intend to hold the investment to maturity, and do not expect that we will be required to sell the security prior to recovery of the amortized cost basis, we will recognize only the credit component of the unrealized loss in earnings by recording an allowance against the amortized cost of the asset as required by Topic 326. We determine the credit component using the difference between the security’s amortized cost basis and the present value of its expected future cash flows, | 7 5 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA PA R T I I discounted using the effective interest method or its estimated collateral value. Any remaining unrealized loss due to factors other than credit is recorded in AOCI. To the extent we hold investments with a fair value less than the amortized cost and we have made the decision to sell the security or it is more likely than not that we will be required to sell the security prior to recovery of its amortized cost basis, we recognize the entire portion of the impairment in earnings. Premiums or discounts on investment securities are amortized or accreted into interest income using the effective interest method. Securitization of Financial Assets We have established various special purpose entities or securitization trusts for the purpose of securitizing certain financial assets. We determined that the trusts used in securitizations are VIEs, as defined in ASC 810. When we conclude that we are not the primary beneficiary of certain trusts because we do not have power over those trusts’ significant activities, we do not consolidate the trust. We typically serve as primary or master servicer of these trusts; however, as the servicer, we do not have the power to make significant decisions impacting the performance of the trusts. We account for transfers of financial assets to these securitization trusts as sales pursuant to ASC 860, Transfers and Servicing (“ASC 860”), when we have concluded the transferred assets have been isolated from the transferor (i.e., put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership) and we have surrendered control over the transferred assets. When we are unable to conclude that we have been sufficiently isolated from the securitized financial assets, we treat such trusts as secured borrowings, retaining the assets on our balance sheet and recording the amounts due to the trust investor as non-recourse debt. For transfers treated as sales under ASC 860, we have received true-sale-at-law and non-consolidation legal opinions for all of our securitization trust structures to support our conclusion regarding the transferred financial assets. When we sell financial assets in securitizations, we generally retain interests in the form of servicing rights and residual assets, which we refer to as securitization assets. Gain or loss on the sale of financial assets is calculated based on the excess of the proceeds received from the securitization (less any transaction costs) plus any retained interests obtained over the cost basis of the assets sold. For retained interests, we generally estimate fair value based on the present value of future expected cash flows using our best estimates of the key assumptions of anticipated losses, prepayment rates, and current market discount rates commensurate with the risks involved. Cash flows related to our securitizations at origination are classified as operating activities in our consolidated statements of cash flows. We initially account for all separately recognized servicing assets and servicing liabilities at fair value and subsequently measure such servicing assets and liabilities using the amortization method. Servicing assets and liabilities are amortized in proportion to, and over the period of, estimated net servicing income with servicing income recognized as earned. We assess servicing assets for impairment at each reporting date. If the amortized cost of servicing assets is greater than the estimated fair value, we will recognize an impairment in net income. Our other retained interest in securitized assets, the residual assets, are accounted for similar to available-for-sale debt securities and carried at fair value. Income related to the residual assets is recognized using the effective interest rate method and included in fee income in our income statement. Our residual assets are evaluated for impairment on a quarterly basis. A residual asset is impaired if its fair value is less than its carrying value. The credit component of impairments, if any, are recognized by recording an allowance against the amortized cost of the asset. For changes in expected cash flows, we will calculate a new yield based on the current amortized cost of the residual assets and the revised expected cash flows. This yield is used prospectively to recognize our income related to these assets. Cash and Cash Equivalents Cash and cash equivalents include short-term government securities, certificates of deposit and money market funds, all of which had an original maturity of three months or less at the date of purchase. These securities are carried at their purchase price, which approximates fair value. Restricted Cash Restricted cash includes cash and cash equivalents set aside with certain lenders primarily to support obligations outstanding as of the balance sheet dates. Restricted cash is reported as part of other assets in our consolidated balance sheets. Refer to Note 3 to our financial statements in this Form 10-K for disclosure of the balances of restricted cash included in other assets. Convertible Notes We have issued convertible senior notes that are accounted for in accordance with ASC 470-20, Debt with Conversion and Other Options, and ASC 815, Derivatives and Hedging (“ASC 815”). Under ASC 815, issuers of certain convertible debt instruments are generally required to separately account for the conversion option of the convertible debt instrument as either a derivative or equity, unless it meets the scope exemption for contracts indexed to, and settled in, an issuer’s own equity. Since this conversion option is both indexed to our equity and can only be settled in our common stock, we have met the scope exemption, and therefore, we are not separately accounting for the embedded conversion option. The initial issuance and any principal repayments are classified as financing activities and interest payments are classified as operating activities in our consolidated statements of cash flows. If converted, the carrying value of each convertible note is reclassified into stockholders’ equity. Income Taxes We elected and qualified to be taxed as a REIT for U.S. federal income tax purposes, commencing with our taxable year ended December 31, 2013. We also have taxable REIT subsidiaries (“TRS”) that are taxed separately, and that will generally be subject to U.S. federal, state, and local income taxes as well as taxes of foreign jurisdictions, if any. To qualify as a REIT, we must meet on an ongoing basis several organizational and operational requirements, including a requirement that we currently distribute at least 90% of our REIT’s net taxable income before dividends paid, excluding capital gains, to our stockholders. As a REIT, we are not subject to U.S. federal corporate income tax on that portion of net income that is currently distributed to our owners. 7 6 | HANNON ARMSTRONG | 2021 ANNUAL REPORT ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA PA R T I I We account for income taxes under ASC 740, Income Taxes (“ASC 740”) for our TRS using the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to the differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities from a change in tax rates is recognized in earnings in the period when the new rate is enacted. We evaluate any deferred tax assets for valuation allowances based on an assessment of available evidence including sources of taxable income, prior years taxable income, any existing taxable temporary differences and our future investment and business plans that may give rise to taxable income. We treat any tax credits we receive from our equity investments in renewable energy projects as reductions of federal income taxes of the year in which the credit arises. Any deferred tax impacts resulting from transfers of assets to or from our TRS are recorded as an adjustment to additional paid-in capital, as it is a transfer amongst entities under common control. We apply ASC 740 with respect to how uncertain tax positions should be recognized, measured, presented, and disclosed in the financial statements. This guidance requires the accounting and disclosure of tax positions taken or expected to be taken in the course of preparing our tax returns to determine whether the tax positions are “more likely than not” to be sustained by the applicable tax authority. We are required to analyze all open tax years, as defined by the statute of limitations, for all major jurisdictions, which includes U.S. federal and certain states. Equity-Based Compensation In 2013, we adopted the 2013 Hannon Armstrong Sustainable Infrastructure Capital, Inc. Equity Incentive Plan (as amended, the “2013 Plan”), which provides for grants of stock options, stock appreciation rights, restricted stock units, shares of restricted common stock, phantom shares, dividend equivalent rights, long-term incentive- plan units (“LTIP units”) and other restricted limited partnership units issued by our Operating Partnership and other equity-based awards. From time to time, we may grant equity or equity-based awards as compensation to our independent directors, employees, advisors, consultants and other personnel under our 2013 Plan. Certain awards earned under the plan are based on achieving various performance targets, which are generally earned between 0% and 200% of the initial target, depending on the extent to which the performance target is met. In addition to performance targets, certain LTIP units issued by our Operating Partnership also require a certain level of appreciation of partnership interests to occur before parity is reached and LTIP units can be converted to limited partnership units. We record compensation expense for grants made under the 2013 Plan in accordance with ASC 718, Compensation—Stock Compensation. We record compensation expense for unvested grants that vest solely based on service conditions on a straight-line basis over the vesting period of the entire award based upon the fair market value of the grant on the date of grant. Fair market value for restricted common stock is based on our share price on the date of grant. For awards where the vesting is contingent upon achievement of certain performance targets, compensation expense is measured based on the fair market value on the grant date and is recorded over the requisite service period (which includes the performance period). Actual performance results at the end of the performance period determines the number of shares that will ultimately be awarded. We have also issued awards where the vesting is contingent upon service being provided for a defined period and certain market conditions being met. The fair value of these awards, as measured at the grant date, is recognized over the requisite service period, even if the market conditions are not met. The grant date fair value of these awards was developed by an independent appraiser using a Monte Carlo simulation. Earnings Per Share We compute earnings per share of common stock in accordance with ASC 260, Earnings Per Share. Basic earnings per share is calculated by dividing net income attributable to controlling stockholders (after consideration of the earnings allocated to unvested grants under the 2013 Plan, if applicable) by the weighted-average number of shares of common stock outstanding during the period excluding the weighted average number of unvested grants under the 2013 Plan, if applicable (“participating securities” as defined in Note 12 to our financial statements in this Form 10-K). Diluted earnings per share is calculated by dividing net income attributable to controlling stockholders (after consideration of the earnings allocated to unvested grants under the 2013 Plan, if applicable) by the weighted-average number of shares of common stock outstanding during the period plus other potential common stock instruments if they are dilutive. Other potentially dilutive common stock instruments include our unvested restricted stock, other equity-based awards, and convertible notes. The restricted stock and other equity-based awards are included if they are dilutive using the treasury stock method. The treasury stock method assumes that theoretical proceeds received for future service provided is used to purchase shares of treasury stock at the average market price per share of common stock, which is deducted from the total shares of potential common stock included in the calculation. When unvested grants are dilutive, the earnings allocated to these dilutive unvested grants are not deducted from the net income attributable to controlling stockholders when calculating diluted earnings per share. The convertible notes are included if they are dilutive using the if- converted method. The if-converted method removes interest expense related to the convertible notes from the net income attributable to controlling stockholders and includes the weighted average shares of potential common stock over the period issuable upon conversion of the note. No adjustment is made for shares of potential common stock that are anti-dilutive during a period. Segment Reporting We make equity and debt investments in the climate solutions markets. We manage our business as a single portfolio and report all of our activities as one business segment. Recently Issued Accounting Pronouncements There were no accounting standards that became effective in the year ended December 31, 2021 that had a material effect on our consolidated financial statements and related disclosures. Accounting standards updates issued before February 22, 2022 and effective after December 31, 2021, are not expected to have a material effect on our consolidated financial statements and related disclosures. | 7 7 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA PA R T I I Fair Value Measurements 3. Fair value is defined as the price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. The fair value accounting guidance provides a three-level hierarchy for classifying financial instruments. The levels of inputs used to determine the fair value of our financial assets and liabilities carried on the balance sheet at fair value and for those which only disclosure of fair value is required are characterized in accordance with the fair value hierarchy established by ASC 820, Fair Value Measurements. Where inputs for a financial asset or liability fall in more than one level in the fair value hierarchy, the financial asset or liability is classified in its entirety based on the lowest level input that is significant to the fair value measurement of that financial asset or liability. We use our judgment and consider factors specific to the financial assets and liabilities in determining the significance of an input to the fair value measurements. As of December 31, 2021 and December 31, 2020, only our residual assets related to our securitization trusts and investments were carried at fair value on the consolidated balance sheets on a recurring basis. The three levels of the fair value hierarchy are described below: z Level 1—Quoted prices (unadjusted) in active markets that are accessible at the measurement date. z Level 2—Observable prices that are based on inputs not quoted on active markets, but corroborated by market data. z Level 3—Unobservable inputs are used when little or no market data is available. The tables below illustrate the estimated fair value of our financial instruments on our balance sheet. Unless otherwise discussed below, fair value for our Level 2 and Level 3 measurements is measured using a discounted cash flow model, contractual terms and inputs which consist of base interest rates and spreads over base rates which are based upon market observation and recent comparable transactions. An increase in these inputs would result in a lower fair value and a decline would result in a higher fair value. Our senior unsecured notes and convertible notes are valued using a market based approach and observable prices. The receivables held-for-sale, if any, are carried at the lower of cost or fair value.

FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA PA R T I I Non-recurring Fair Value Measurements Our financial statements may include non-recurring fair value measurements related to acquisitions and non-monetary transactions, if any. Assets acquired in a business combination are recorded at their fair value. We may use third party valuation firms to assist us with developing our estimates of fair value. See Note 6 for a discussion of a fair value measurement recorded during the year ended December 31, 2021 related to an equity method investment. Concentration of Credit Risk Commercial and government receivables, real estate leases, and debt investments consist primarily of receivables from various projects, U.S. federal government-backed receivables, and investment grade state and local government receivables and do not, in our view, represent a significant concentration of credit risk. Additionally, certain of our investments are collateralized by projects concentrated in certain geographic regions throughout the United States. These investments typically have structural credit protections to mitigate our risk exposure and, in most cases, the projects are insured for estimated physical loss which helps to mitigate the possible risk from these concentrations. We had cash deposits that are subject to credit risk as shown below: (in millions) Cash deposits Restricted cash deposits (included in other assets) TOTAL CASH DEPOSITS Amount of cash deposits in excess of amounts federally insured Non-Controlling Interest 4. Units of limited partnership interests in the Operating Partnership (“OP units”) that are owned by limited partners other than us are included in non-controlling interest on our consolidated balance sheets. The non-controlling interest holders are generally allocated their pro rata share of income, other comprehensive income and equity transactions. The outstanding OP units held by outside limited partners represent less than 1% of our outstanding OP units and are redeemable by the limited partners for cash, or at our option, for a like number of shares of our common stock. No OP units were exchanged by non-controlling interest holders during the year ended December 31, 2021. Non- controlling interest holders exchanged 57,400 OP units for the same number of shares of our common stock during the year ended December 31, 2020. We have also granted to members of our leadership team and directors LTIP Units pursuant to the 2013 Plan. The LTIP Units issued to employees are held by HASI Management HoldCo LLC. The LTIP Units are designed to qualify as profits interests in the Operating Partnership and initially will have a capital account balance of zero and, therefore, will not have full parity with OP units with respect to December 31, 2021 2020 $ $ $ 226 $ 25 251 $ 249 $ 286 24 310 309 liquidating distributions or other rights. However, the amended and restated agreement of limited partnership of the Operating Partnership (the “OP Agreement”) provides that “book gains,” or economic appreciation, in the Operating Partnership will be allocated first to the LTIP Units until the capital account per LTIP Units is equal to the capital account per-unit of the OP units. Under the terms of the OP Agreement, the Operating Partnership will revalue its assets upon the occurrence of certain specified events, and any increase in valuation from the time of grant until such event will be allocated first to the holders of LTIP Units to equalize the capital accounts of such holders with the capital accounts of OP unit holders. Once this has occurred, the LTIP Units will achieve full parity with the OP units for all purposes, including with respect to liquidating distributions and redemption rights. In addition to these attributes, there are vesting and settlement conditions similar to our other equity-based awards as discussed in Notes 2 and 11 to our financial statements in this Form 10-K. | 8 1 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA PA R T I I Securitization of Financial Assets 5. The following summarizes certain transactions with securitization trusts: (in millions) Gains on securitizations Cost of financial assets securitized Proceeds from securitizations Residual and servicing assets Cash received from residual and servicing assets As of and for the year ended December 31, 2021 2020 2019 $ 68 $ 50 $ 810 878 210 18 292 342 164 12 24 853 877 124 7 In connection with securitization transactions, we typically retain servicing responsibilities and residual assets. We generally receive annual servicing fees that are typically up to 0.20% of the outstanding balance. We may periodically make servicer advances, that are subject to credit risk. Included in securitization assets in our consolidated balance sheets are our servicing assets at amortized cost and our residual assets at fair value. Our residual assets are subordinate to investors’ interests, and their values are subject to credit, prepayment and interest rate risks on the transferred financial assets. Other than our securitization assets representing these residual interests in the trusts’ assets, the investors and the securitization trusts have no recourse to our other assets for failure of debtors to pay when due. In computing gains and losses on securitizations, we use discount rates based on a review of comparable market transactions including Level 3 unobservable inputs which consist of base interest rates and spreads over these base rates. Depending on the nature of the transaction risks, the discount rate ranged from 2% to 8%. As of December 31, 2021 and December 31, 2020, our managed assets totaled $8.8 billion and $7.2 billion, respectively, of which $5.2 billion and $4.3 billion, respectively, were securitized assets held in unconsolidated securitization trusts. There were no securitization credit losses in the years ended December 31, 2021, 2020, or 2019. As of December 31, 2021, there were no material payments from debtors to the securitization trusts that were greater than 90 days past due. Receivables from contracts for the installation of energy efficiency and other technologies are the source of cash flows for $104 million of our securitization residual assets. These technologies are installed in facilities owned by, or operated for or by, federal, state or local government entities where the ultimate obligor for the receivable is a governmental entity. The contracts may have guarantees of energy savings from third-party service providers, which typically are entities rated investment grade by an independent rating agency. The remainder of our securitization residual assets are related to contracts where the underlying cash flows are secured by an interest in real estate which are typically senior in terms of repayment to other financings. Our Portfolio 6. As of December 31, 2021, our Portfolio included approximately $3.6 billion of equity method investments, receivables, real estate and investments on our balance sheet. The equity method investments represent our non-controlling equity investments in renewable energy and energy efficiency projects and land. The receivables and investments are typically collateralized by contractually committed debt obligations of government entities or private high credit quality obligors and are often supported by additional forms of credit enhancement, including security interests and supplier guaranties. The real estate is typically land and related lease intangibles for long-term leases to wind and solar projects. In developing and evaluating performance against our credit criteria, we consider a number of qualitative and quantitative criteria including a project’s operating results, loan-to-value ratio, any cash reserves, the ability of expected cash from operations to cover the cash flow requirements currently and into the future, key terms of the transaction, the ability of the borrower to refinance the transaction, the financial and operating capability of the borrower, its sponsors or the obligor as well as any guarantors and the project’s collateral value. In addition, we consider the overall economic environment, the climate solutions sector, the effect of local, industry and broader economic factors, the impact of any variation in weather and the historical and anticipated trends in interest rates, defaults and loss severities for similar transactions. 8 2 | HANNON ARMSTRONG | 2021 ANNUAL REPORT ITEM 8.

(2) This category includes our assets where based on our credit criteria and performance to date we believe there is a moderate level of risk to not receiving some or all of our invested capital. (3) This category includes our assets where based on our credit criteria and performance to date, we believe there is substantial doubt regarding our ability to recover some or all of our invested capital. Included in this category are two commercial receivables with a combined total carrying value of approximately $8 million as of December 31, 2021 which we have held on non-accrual status since 2017. We expect to continue to pursue our legal claims with regards to these assets. This category previously contained an equity method investment in a wind project with no book value due to our allocation of impairment losses recorded by the project sponsor. We sold this equity method investment in the third quarter for nominal proceeds. (4) Total reconciles to the total of the government receivables and commercial receivables lines of the consolidated balance sheets. (5) Some of the individual projects included in portfolios that make up our equity method investments have government off-takers. As they are part of large portfolios, they are not classified separately. (6) Average remaining balance is calculated gross of allowance for loss on receivables and excludes approximately 174 transactions each with outstanding balances that are less than $1 million and that in the aggregate total $84 million. Receivables As of December 31, 2021 our allowance for loan losses was $36 million based on our expectation for credit losses over the lives of the receivables in our Portfolio. During 2021, our reserve was unchanged, as additional allowances associated with loans and loan commitments were offset by the release of certain loan-specific reserves. Below is a summary of the carrying value, expected loan funding commitments, and allowance by type of receivable or “Portfolio Segment,” as defined by Topic 326, as of December 31, 2021 and 2020: (in millions) Commercial(1) Government(2) TOTAL December 31, 2021 December 31, 2020 Gross Carrying Value Loan Funding Commitments Allowance Gross Carrying Value Loan Funding Commitments Allowance $ $ 1,335 $ 184 $ 125 — 1,460 $ 184 $ 36 — 36 $ $ 1,002 $ 282 $ 248 — 1,250 $ 282 $ 36 — 36 | 8 3 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA PA R T I I (1) As of December 31, 2021, this category of assets include $776 million of mezzanine loans made on a non-recourse basis to special purpose subsidiaries of residential solar companies which are secured by residential solar assets where we rely on certain limited indemnities, warranties, and other obligations of the residential solar companies or their other subsidiaries. Approximately $684 million of our commercial receivables are loans made to entities in which we also have non-controlling equity investments of approximately $108 million. This total also includes $48 million of lease agreements where we hold legal title to the underlying real estate which are treated under GAAP as receivables since they were deemed to be failed sale/leaseback transactions as described in Note 2. Risk characteristics of our commercial receivables include a project’s operating risks, which include the impact of the overall economic environment, the climate solutions sector, the effect of local, industry, and broader economic factors, the impact of any variation in weather and trends in interest rates. We use assumptions related to these risks to estimate an allowance using a discounted cash flow analysis or the PD/LGD method as discussed in Note 2. All of our commercial receivables are included in Performance Rating 1 in the Portfolio Performance table above, except for $11 million of receivables included in Performance Category 2 and the $8 million of receivables we have placed on non-accrual status which are included in Performance Rating 3. For those assets in Performance Rating 1, the credit worthiness of the obligor combined with the various structural protections of our assets cause us to believe we have a low risk we will not receive our invested capital, however we recorded a $25 million allowance on these $1.3 billion in assets as a result of lower probability assumptions utilized in our allowance methodology. (2) As of December 31, 2021, our government receivables include $28 million of U.S. federal government transactions and $97 million of transactions where the ultimate obligors are state or local governments. Risk characteristics of our government receivables include the energy savings or the power output of the projects and the ability of the government obligor to generate revenue for debt service, via taxation or other means. Transactions may have guarantees of energy savings or other performance support from third-party service providers, which typically are entities, directly or whose ultimate parent entity is, rated investment grade by an independent rating agency. All of our government receivables are included in Performance Rating 1 in the Portfolio Performance table above. Our allowance for government receivables is primarily calculated by using PD/LGD methods as discussed in Note 2. Our expectation of credit losses for these receivables is immaterial given the high credit-quality of the obligors. The following table reconciles our beginning and ending allowance for loss on receivables by Portfolio Segment for the year ended December 31, 2021: (in millions) Beginning balance - January 1, 2020(1) Provision for loss on receivables Ending balance - December 31, 2020 Provision for loss on receivables Ending balance - December 31, 2021 Commercial Government $ $ 26 $ 10 36 — 36 $ — — — — — (1) Balance as of the adoption of Topic 326, which includes the pre-tax allowance for loss on receivables of $17 million recorded upon adoption which reflects our estimated loss as of that date under the new standard as well as the $8 million of receivables which were previously on non-accrual status and fully reserved. Other than the $8 million of receivables discussed above with a Performance Rating of 3, we have no receivables which are on non-accrual status.

FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA PA R T I I Real Estate Our real estate is leased to renewable energy projects, typically under long-term triple net leases with expiration dates that range between the years 2033 and 2057 under the initial terms and 2047 and 2080 if all renewals are exercised. The components of our real estate portfolio as of December 31, 2021 and 2020, were as follows: (in millions) Real estate Land Lease intangibles Accumulated amortization of lease intangibles REAL ESTATE December 31, 2021 2020 $ $ 269 $ 104 (17) 356 $ 269 104 (14) 359 As of December 31, 2021, the future amortization expense of the intangible assets and the future minimum rental income payments under our land lease agreements are as follows: (in millions) Year Ending December 31, 2022 2023 2024 2025 2026 Thereafter TOTAL Future Amortization Expense Minimum Rental Payments $ $ 3 $ 3 3 3 3 72 87 $ 22 24 24 24 24 723 841 Equity Method Investments We have made non-controlling equity investments in a number of renewable energy and energy efficiency projects as well as in a joint venture that owns land with long-term triple net lease agreements to several solar projects that we account for as equity method investments. As of December 31, 2021, we held the following equity method investments: (in millions) Investment Date Various Jupiter Equity Holdings, LLC December 2020 Lighthouse Partnerships(1) March 2020 University of Iowa Energy Collaborative Holdings LLC Various Other investees TOTAL EQUITY METHOD INVESTMENTS (1) Represents the total of three equity investments in a portfolio of a renewable energy projects discussed below. $ $ 540 390 123 707 1,760 Investee Carrying Value Jupiter Equity Holdings, LLC We have a preferred equity interest in Jupiter Equity Holdings, LLC (“Jupiter”) that owns nine operating onshore wind projects and four operating utility-scale solar projects with an aggregate capacity of approximately 2.3 gigawatts. We have made capital contributions to Jupiter of approximately $540 million related to these projects. The projects feature cash flows from fixed-price power purchase agreements and financial hedges with a weighted average contract life of 13 years, contracted with highly creditworthy off-takers and counterparties. Jupiter is governed by an amended and restated limited liability company agreement, dated July 1, 2020, by and among Jupiter, one of our subsidiaries and a subsidiary of the project sponsor, and contains customary terms and conditions. We own 100% of the Class A Units in Jupiter corresponding to 49% of the distributions from Jupiter subject to the preferences discussed below. Most major decisions that may impact Jupiter, its subsidiaries or its assets, require the majority vote of a four person committee in which we and the project sponsor each have two representatives. Through Jupiter, we will be entitled to preferred distributions until certain return targets are | 8 5 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA PA R T I I achieved. Once these return targets are achieved, distributions will be allocated approximately 33% to us and approximately 67% to the sponsor. We and the sponsor each have a right of first offer if the other party desires to transfer any of its equity ownership to a third party on or after July 1, 2023. We use the equity method of accounting to account for our preferred equity interest in Jupiter, and have elected to recognize earnings from this investment one quarter in arrears to allow for the receipt of financial information. Lighthouse Renewables Portfolio In December 2020, we entered into certain agreements relating to the acquisition, ownership and management of approximately $663 million in preferred cash equity investments in three partnerships that expect to own cash equity interests in an approximately 1.6 gigawatt portfolio of onshore wind, utility-scale solar and solar-plus-storage projects (the “Renewables Portfolio”) developed and managed by the project sponsor. In 2021, we modified this structure to include an additional project in the renewables portfolio and to be held through the four partnerships (“Lighthouse Partnerships”), bringing our total expected investment to $870 million. We have made initial investments in the preferred cash equity interests of the Lighthouse Partnerships of approximately $388 million through December 31, 2021, and additional investments are expected to be made in 2022 as the projects become commercially operational. The Renewables Portfolio currently has contracted cash flows with a combined weighted average contract life of greater than 15 years with a diversified group of predominately investment grade corporate, utility, university, and municipal offtakers. In 2021, we made approximately $15 million in equity contributions and made $10 million in member loans to one of the Lighthouse Partnerships for the settlement of hedging activity under one of the project’s power hedge agreements as a result of the February 2021 winter storms in Texas. Each of the Lighthouse Partnerships are or will be governed by a limited liability company agreement between us and the sponsor serving as managing member and contain customary terms and conditions. Most major decisions that may impact each of the Lighthouse Partnerships, its subsidiaries or its assets, require a unanimous vote of the representatives present at a meeting of a review committee in which a quorum is present. The review committee is a four person committee, which includes two Company representatives and two sponsor representatives. Through each Lighthouse Partnership, commencing on a certain date following the effective date of the applicable limited liability company agreement, we will be entitled to preferred distributions until certain return targets of the Renewables Portfolio are achieved. Subject to customary exceptions, no member of a Lighthouse Partnership can transfer any of its equity ownership in any Lighthouse Partnership to a third party without approval of the review committee of that Lighthouse Partnership. We use the equity method of accounting to account for our preferred equity interest in each Lighthouse Partnership, and have elected to recognize earnings from this investment one quarter in arrears to allow for the receipt of financial information. Other Equity Method Investments In 2021 we restructured an equity method investment with a GAAP carrying value of $24 million to convert it to a $17 million loan. The GAAP carrying value of this investment included amounts related to non-cash HLBV income that in normal course would have reversed over time. Upon restructuring, we accelerated the reversal of $7 million of previously recorded non-cash HLBV income included in the carrying value of this investment through income from equity method investments on our income statement. Also in 2021, we had a working capital loan with an outstanding principal balance of $18 million to one of our equity method investments which we exchanged for an additional equity investment in that investee. 7. Credit facilities and commercial paper notes Secured Credit Facilities We have two secured revolving credit facilities (our “Secured Credit Facilities”), a representation-based loan agreement (the “Rep-Based Facility”) and an approval-based loan agreement (the “Approval-Based Facility”) with various lenders, which mature in July 2023. The Rep-Based Facility is a secured revolving limited-recourse credit facility, which we modified in March 2021 to have a maximum outstanding principal amount of $100 million, lowered from a previous amount of $250 million. This modification resulted in a $1.5 million loss due to the acceleration of a portion of the related unamortized financing costs that was recognized in interest expense in 2021. The Approval-Based Facility is a secured revolving recourse credit facility with a maximum outstanding principal amount of $200 million. The following table provides additional detail on our Secured Credit Facilities as of December 31, 2021: (dollars in millions) Outstanding balance Value of collateral pledged to credit facility Available capacity based on pledged assets Weighted average short-term borrowing rate Rep-Based Facility Approval-Based Facility $ — $ 24 11 N/A 50 90 14 2.1% Loans under the Rep-Based Facility bear interest at a rate equal to one-month LIBOR plus 1.40% or 1.85% (depending on the type of collateral) or, in certain circumstances, the Federal Funds Rate plus 0.40% or 0.85% (depending on the type of collateral). Loans under the Approval-Based Facility bear interest at a rate equal to one-month LIBOR plus 1.50% or 2.00% (depending on the type of collateral) or, under certain circumstances, the Federal Funds Rate plus 0.50% or 1.00% (depending on the type of collateral). Inclusion of any financings of the Company in the borrowing base as collateral under the Rep-Based Facility will be subject to the Company 8 6 | HANNON ARMSTRONG | 2021 ANNUAL REPORT ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA PA R T I I making certain agreed upon representations and warranties. We have provided a limited guarantee covering the accuracy of the representations and warranties, and the repayment by the borrowers of certain amounts relating to any such financing is the exclusive remedy with respect to any breach of such representations and warranties under the Rep-Based Facility. Inclusion of any financings of the Company in the borrowing base as collateral under the Approval-Based Facility will be subject to the approval of a super-majority of the lenders, and we have provided a guarantee of the Approval-Based Facility. The amount eligible to be drawn under the Secured Credit Facilities is based on a discount to the value of each included investment based upon the type of collateral or an applicable valuation percentage. The sum of included financings after taking into account the applicable valuation percentages and any changes in the valuation of the financings in accordance with the Secured Credit Facilities determines the borrowing capacity, subject to the overall facility limits described above. Under the Rep-Based Facility, the applicable valuation percentage is 85% in the case of a land-lease obligor or a U.S. Federal Government obligor, 80% in the case of an institutional obligor or state and local obligor, and with respect to other obligors or in certain circumstances, such other percentage as the administrative agent may prescribe. Under the Approval-Based Facility, the applicable valuation percentage is 85% in the case of certain approved financings and 67% or such other percentage as the administrative agent may prescribe. The Approval-Based Facility previously had an outstanding draw with a fixed amortization schedule that was prepaid in 2021. We have approximately $2 million of remaining unamortized financing costs associated with the Secured Credit Facilities that have been capitalized and included in other assets on our balance sheet and are being amortized on a straight-line basis over the term of the Secured Credit Facilities. Administrative fees are payable annually to the administrative agent under each of the Secured Credit Facilities and letter agreements with the administrative agent. Under the Rep- Based Facility, we pay to the administrative agent on each monthly payment date, for the benefit of the lenders, certain availability fees for the Rep-Based Facility equal to 0.60%, divided by 365 or 366, as applicable, multiplied by the excess of the available total commitments under the Rep-Based Facility over the actual amount borrowed under the Rep-Based Facility. The Secured Credit Facilities contain terms, conditions, covenants, and representations and warranties that are customary and typical for a transaction of this nature, including various affirmative and negative covenants, and limitations on the incurrence of liens and indebtedness, investments, fundamental organizational changes, dispositions, changes in the nature of business, transactions with affiliates, use of proceeds and stock repurchases. We were in compliance with our covenants as of December 31, 2021. The Secured Credit Facilities also include customary events of default, including the existence of a default in more than 50% of the value of underlying financings. The occurrence of an event of default may result in termination of the credit facilities, acceleration of amounts due under the Secured Credit Facilities, and accrual of default interest at a rate of LIBOR plus 2.00% in the case of both the Rep-Based Facility and the Approval-Based Facility. Unsecured Revolving Credit Facilities In April 2021, we entered into a $400 million 364-day unsecured revolving credit facility (“Existing Revolving Credit Facility”) pursuant to a revolving credit agreement with a syndicate of lenders, replacing our then-existing $50 million unsecured revolving credit facility entered into in February 2021. As of December 31, 2021, the outstanding balance on the Existing Revolving Credit Facility was $50 million, and it beared interest at a rate of 2.35%. As of December 31, 2021, we had less than $1 million of remaining unamortized financing costs associated with the Existing Revolving Credit Facility that have been capitalized and included in other assets on our balance sheet and are being amortized on a straight-line basis over the term of the Existing Revolving Credit Facility. In February 2022, the Existing Revolving Credit Facility was replaced with a $600 million unsecured revolving credit facility (“New Revolving Credit Facility”), which matures in February 2025. The Existing Revolving Credit Facility bears interest at a rate of the LIBOR or prime rate plus applicable margins based on our current credit rating, which may be adjusted downward up to 0.05% to the extent our Portfolio achieves certain targeted levels of carbon emissions avoidance as measured by our CarbonCount metric. As of the inception of the unsecured revolving credit facility, the applicable margins are 2.25% for LIBOR-based loans and 1.25% for prime rate- based loans. The New Revolving Credit facility bears interest at a rate of SOFR plus applicable margins, which may be adjusted downward up to 0.10% to the extent our Portfolio achieves certain targeted levels of carbon emissions avoidance. The initial applicable margins are 1.875% for Term SOFR Rate-based loans and 0.875% for prime rate- based loans. Both unsecured revolving credit facilities have commitment fee based on our current credit rating. Both unsecured revolving credit facilities contain terms, conditions, covenants, and representations and warranties that are customary and typical for transactions of this nature, including various affirmative and negative covenants, and limitations on the incurrence of liens and indebtedness, investments, fundamental organizational changes, dispositions, changes in the nature of business, transactions with affiliates, use of proceeds, stock repurchases, and dividends we can declare. Both unsecured revolving credit facilities also include customary events of default and remedies. At our option, upon maturity of the New Revolving Credit Facility, we have the ability to convert amounts borrowed into term loans for a fee equal to 1.875% of the term loan amounts. CarbonCount Green Commercial Paper Note Program In September 2021, we entered into an agreement allowing us to issue commercial paper notes, in amounts up to $100 million outstanding at any time. We obtained an irrevocable direct-pay letter of credit in an amount not to exceed $100 million from Bank of America, N.A, to support these obligations which expires in December 2022. Commercial paper notes will not be redeemable, will not be subject to voluntary prepayment and are not to exceed 397 days. The proceeds of our commercial paper notes are used to acquire or refinance, in whole or in part, eligible green projects, including assets that are neutral to negative on incremental carbon emissions. In December 2021, we issued $50 million in green commercial paper notes which mature in March 2022, bearing a total borrowing rate of 1.26%. | 8 7 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA PA R T I I Green commercial paper notes will be issued at a discount based on market pricing, subject to broker fees of 0.10%. For issuance of the letter of credit, we will pay 0.95% on any drawn letter of credit amounts to Bank of America, N.A., and 0.40% on any unused letter of credit capacity. Fees paid on the drawn letters of credit may be reduced by up to 0.05% to the extent our Portfolio achieves certain targeted levels of carbon emissions avoidance as measured by our CarbonCount metric. As of December 31, 2021, we have approximately $1 million of remaining unamortized financing costs associated with the commercial paper program and associated letter of credit that have been capitalized and included in other assets on our balance sheet and are being amortized on a straight-line basis over the term of the commercial paper program. The associated letter of credit contains terms, conditions, covenants, and representations and warranties that are customary and typical for a transaction of this nature, including various affirmative and negative covenants, and limitations on the incurrence of liens and indebtedness, investments, fundamental organizational changes, dispositions, changes in the nature of business, transactions with affiliates, use of proceeds, stock repurchases and dividends we declare. The letter of credit also includes customary events of default and remedies. 8.

(2) In 2021, contractual terms were modified resulting in the deconsolidation of both this debt and the related pledged assets. We recognized a loss of approximately $3 million, which is included in gain on sale of receivables and investments in our income statement. (3) Other non-recourse debt consists of various debt agreements used to finance certain of our receivables. Scheduled debt service payment requirements are equal to or less than the cash flows received from the underlying receivables. (4) The total collateral pledged against our non-recourse debt was $573 million and $723 million as of December 31, 2021 and December 31, 2020, respectively. In addition, $24 million and $23 million of our restricted cash balance was pledged as collateral to various non-recourse loans as of December 31, 2021 and December 31, 2020, respectively. We have pledged the financed assets, and typically our interests in one or more parents or subsidiaries of the borrower that are legally separate bankruptcy remote special purpose entities as security for the non-recourse debt. There is no recourse for repayment of these obligations other than to the applicable borrower and any collateral pledged as security for the obligations. Generally, the assets and credit of these entities are not available to satisfy any of our other debts and obligations. The creditors can only look to the borrower, the cash flows of the pledged assets and any other collateral pledged, to satisfy the debt and we are not otherwise liable for nonpayment of such cash flows. The debt agreements contain terms, conditions, covenants, and representations and warranties that are customary and typical for transactions of this nature, including limitations on the incurrence of liens and indebtedness, investments, fundamental organizational changes, dispositions, changes in the nature of business, transactions with affiliates, use of proceeds and stock repurchases. The agreements also include customary events of default, the occurrence of which may result in termination of the agreements, acceleration of amounts due, and accrual of default interest. We typically act as servicer for the debt transactions. We were in compliance with all covenants as of December 31, 2021 and 2020. We have guaranteed the accuracy of certain of the representations and warranties and other obligations of certain of our subsidiaries under certain of the debt agreements and provided an indemnity against certain losses from “bad acts” of such subsidiaries including fraud, failure to disclose a material fact, theft, misappropriation, voluntary bankruptcy or unauthorized transfers. 8 8 | HANNON ARMSTRONG | 2021 ANNUAL REPORT ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA PA R T I I The stated minimum maturities of non-recourse debt as of December 31, 2021, were as follows: (in millions) Year Ending December 31, 2022 2023 2024 2025 2026 Thereafter Total minimum maturities Unamortized financing costs TOTAL NON-RECOURSE DEBT Future minimum maturities $ $ 25 26 30 26 25 308 440 (10) 430 The stated minimum maturities of non-recourse debt above include only the mandatory minimum principal payments. To the extent there are additional cash flows received from our investments in climate solutions projects serving as collateral for certain of our non-recourse debt facilities, these additional cash flows may be required to be used to make additional principal payments against the respective debt. Any additional principal payments made due to these provisions may impact the anticipated balance at maturity of these financings. To the extent there are not sufficient cash flows received from those investments pledged as collateral, the investor has no recourse against other corporate assets to recover any shortfalls. Senior Unsecured Notes We have outstanding senior unsecured notes issued jointly by certain of our TRS and are guaranteed by the Company and certain other subsidiaries (the “Senior Unsecured Notes”), including $1 billion The following are summarized terms of the Senior Unsecured Notes: of senior notes due 2026 (“2026 Notes”) issued in June 2021. Proceeds from the 2026 Notes were used to redeem the 2024 Notes as described below. The Senior Unsecured Notes are subject to covenants that limit our ability to incur additional indebtedness and require us to maintain unencumbered assets of not less than 120% of our unsecured debt. These covenants will terminate on any date at which the Senior Unsecured Notes have been rated investment grade by two of the three major credit rating agencies and no event of default has occurred. We are in compliance with all of our covenants as of December 31, 2021 and 2020. The Senior Unsecured Notes impose certain requirements in the event that we merge with or sell substantially all of our assets to another entity. The proceeds of our Senior Unsecured Notes are used to acquire or refinance, in whole or in part, eligible green projects, including assets that are neutral to negative on incremental carbon emissions.

We subsequently issued $150 million of the $500 million aggregate principal amount of the 2024 Notes for total proceeds of $157 million ($155 million net of issuance costs) at an effective interest rate of 4.13%. The 2024 Notes were redeemed in June 2021 using a portion of the proceeds from the 2026 Notes. We recognized a loss of $15 million upon redemption for the redemption premium and the acceleration of debt issuance cost and premium amortization which is recorded in interest expense in our income statement. (2) Prior to this date, we may redeem, at our option, some or all of the 2025 Notes or 2026 Notes for the outstanding principal amount plus the applicable “make-whole” premium as defined in the indenture governing the 2025 Notes or 2026 Notes plus accrued and unpaid interest through the redemption date. In addition, prior to this date, we may redeem up to 40% of the Senior Unsecured Notes using the proceeds of certain equity offerings at a price equal to par plus the coupon percentage of the principal amount thereof, plus accrued but unpaid interest, if any, to, but excluding, the applicable redemption date. On, or subsequent to, this date we may redeem the 2025 or 2026 Notes in whole or in part at redemption prices defined in the indenture governing the 2025 Notes or 2026 Notes, plus accrued and unpaid interest though the redemption date. (3) We issued the $375 million aggregate principal amount of the 2030 Notes for total proceeds of $371 million ($367 million net of issuance costs) at an effective interest rate of 3.87%. (4) Prior to this date, we may, at our option on one or more occasions redeem up to 40% of the 2030 Notes using the proceeds of certain equity offerings at a price equal to 103.75% of the principal amount thereof; plus accrued but unpaid interest, if any, to, but excluding the applicable redemption date. At any point prior to maturity, we may redeem, at our option, some or all of the 2030 Notes plus the applicable “make-whole” premium as defined in the indenture governing the 2030 Notes plus accrued and unpaid interest through the redemption date. | 8 9 HANNON ARMSTRONG | 2021 ANNUAL REPORT ITEM 8.

For both the 2022 Convertible Senior Notes and the 2023 Convertible Senior Notes, following the occurrence of a make-whole fundamental change, we will, in certain circumstances, increase the conversion rate for a holder that converts its convertible notes in connection with such make-whole fundamental change. There are no cash settlement provisions in the convertible notes and the conversion option can only be settled through physical delivery of our common stock. Additionally, upon the occurrence of certain fundamental changes involving us, holders of the convertible notes may require us to redeem all or a portion of their convertible notes for cash at a price of 100% of the principal amount outstanding, plus accrued and unpaid interest. We have a redemption option to call the 2022 Convertible Senior Notes prior to maturity (i) on or after March 1, 2022 and (ii) at any time if such a redemption is deemed reasonably necessary to preserve our qualification as a REIT, with the holder of the notes having the option of converting prior to our redemption becoming effective. The redemption price will be equal to the principal of the notes being redeemed, plus accrued and unpaid interest.

FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA PA R T I I 9. Commitments and Contingencies Leases Guarantees and Other Commitments We lease office space at our headquarters in Annapolis, Maryland under an operating lease entered into in 2011 and amended in 2013 and 2017. Lease payments under this lease commenced in 2012 and incremental payments related to the amendments commenced in 2014 and 2017. The lease expires in 2027. In 2021, we signed a lease for new office space which expires in 2033, and expect to begin subleasing the prior space in 2023. The leases provide for operating expense reimbursements and annual escalations that are amortized over the respective lease terms on a straight-line basis. Rent expense was less than $1 million for each of the years ended December 31, 2021, 2020, and 2019, respectively. Future gross minimum lease payments are approximately $1 million per year during the remaining term of the leases. Litigation The nature of our operations exposes us to the risk of claims and litigation in the normal course of our business. We are not currently subject to any legal proceedings that are probable of having a material adverse effect on our financial position, results of operations or cash flows. We made a guarantee related to the financing of one of our joint venture entities that owns debt securities of energy efficiency projects. The entity entered into a financing arrangement where we had guaranteed the obligations of the entity related to this financing, which includes collateral posting requirements as well as repayment of the financing at maturity in December 2021, which was paid as scheduled. We have no performance obligations remaining under this guarantee as of December 31, 2021. In connection with some of our transactions, we have provided certain limited representations, warranties, covenants and/or provided an indemnity against certain losses resulting from our own actions, including related to certain investment tax credits. As of December 31, 2021, there have been no such actions resulting in claims against the Company. COVID-19 The COVID-19 global pandemic has brought forth uncertainty and disruption to the global economy. As of December 31, 2021, we have not recorded any contingencies on our balance sheet related to COVID-19 with the exception of any allowances related to our receivables described in Note 6. To the extent COVID-19 continues to cause dislocations in the global economy, our financial condition, results of operations, and cash flows may be adversely impacted. Income Tax 10. We recorded an income tax benefit (expense) of approximately $(17) million for the year ended December 31, 2021, a $3 million tax benefit (expense) for the year ended December 31, 2020, and an $(8) million tax benefit (expense) for the year for the year ended 2019 related to the activities of our TRS. The federal income tax expense and benefits recorded were determined using a rate of 21%. Our deferred tax assets and liabilities were measured using a federal rate of 21%.

Our deferred tax liability is included in accounts payable, accrued expenses and other on our consolidated balance sheet. Deferred income taxes represent the tax effect from continuing operations of the differences between the book and tax basis of assets and liabilities.

Approximately, $87 million of our NOLs will begin to expire in 2034. If our TRS entities were to experience a change in control as defined in Section 382 of the Internal Revenue Code, the TRS’s ability to utilize NOLs in the years after the change in control would be limited. Similar rules and limitation may apply for state tax purposes as well. Of our NOLs, $219 million were added in taxable years after 2018 which are not subject to expiration but are limited to 80% of taxable income. Our tax credits begin to expire in 2034. We have no examinations in progress, none are expected at this time, and years 2018 through 2021 are open. As of December 2021 and 2020, we had no uncertain tax positions. Our policy is to recognize interest expense and penalties related to income tax matters as a component of general and administrative expense. There were no accrued interest and penalties as of December 31, 2021 and 2020, and no interest and penalties were recognized during the years ended December 31, 2021, 2020, or 2019.

Both the net income or loss attributable to the non-controlling OP units and the non-controlling limited partners’ outstanding OP units have been excluded from the basic earnings per share and the diluted earnings per share calculations attributable to common stockholders. Unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and are excluded from net income available to common shareholders in the computation of earnings per share pursuant to the two-class method. Certain share-based awards are included in the diluted share count to the extent they are dilutive as discussed in Note 2. To the extent our Senior Convertible Notes are dilutive under the if-converted method, we add back the interest expense to the numerator and include the weighted average shares of potential common stock over the period issuable upon conversion of the note in the denominator in calculating dilutive EPS as described in Note 2.

Based on that review and evaluation, the chief executive officer and chief financial officer have concluded that our current disclosure controls and procedures, as designed and implemented, were effective. Notwithstanding the foregoing, a control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that it will detect or uncover failures within our company to disclose material information otherwise required to be set forth in our periodic reports. Management’s Report on Internal Control Over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, our principal executive and principal financial officers and effected by our board of directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. GAAP and includes those policies and procedures that: • pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of our company; 9 8 | • provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and • provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our 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. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate. Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2021. In making this assessment, our management used criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013 Framework). Based on this assessment, our management believes that, as of December 31, 2021, our internal control over financial reporting was effective based on those criteria. Changes in Internal Control Over Financial Reporting There have been no changes in our internal control over financial reporting that occurred during the quarter ended December 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
