Corporate Profile Wesco International (NYSE: WCC) builds, connects, powers and protects the world. Headquartered in Pittsburgh, Pennsylvania, Wesco is a FORTUNE 500® company with more than $22 billion in annual sales and a leading provider of business-to-business distribution, logistics services and supply chain solutions. Wesco offers a best-in-class product and services portfolio of Electrical and Electronic Solutions, Communications and Security Solutions, and Utility and Broadband Solutions. The Company employs approximately 20,000 people, partners with the industry’s premier suppliers, and serves thousands of customers around the world. With millions of products, end-to-end supply chain services, and leading digital capabilities, Wesco provides innovative solutions to meet customer needs across commercial and industrial businesses, contractors, government agencies, educational institutions, telecommunications providers, and utilities. Wesco operates nearly 800 branches, warehouses and sales offices in more than 50 countries, providing a local presence for customers and a global network to serve multi-location businesses and global corporations. To Our Stockholders, Employees, and Business Partners Strengthened balance sheet – rapidly de-levered our balance sheet by three turns, one year ahead of schedule. Superior shareholder returns – since closing the Anixter acquisition in June 2020 through the end of 2023, total shareholder return was 353% compared to 62% for the S&P 500. As we begin 2024, we remain laser-focused on the continued effective execution of our three enterprise strategies: 1. Extend our industry-leading scale and value proposition. 2. Further develop our team and our culture of excellence. 3. Digitalize and transform our B2B business. “ Following two years of double-digit sales growth, we set a new company record again in 2023 with 5% growth to over $22 billion in sales. ” Following two years of double-digit sales growth, we set a new company record again in 2023 with 5% growth to over $22 billion in sales. As a leading provider of business-to- business supply chain solutions, our Wesco team navigated through a mixed economic environment last year, while managing changing customer buying patterns as supply chains healed. We saw continued growth in utility, data center, industrial, security and network infrastructure applications, while others underperformed including broadband, select OEM and specific construction-related sectors. We finished the year with backlog near a historical high level. Our free cash flow generation strengthened as we moved through the year, and we returned one third of our full-year cash flow to shareholders through the initiation of a common stock dividend and share repurchases. 2023 also marked the successful completion of our three-year integration of Anixter. The acquisition of Anixter literally transformed Wesco. This combination not only established Wesco as the clear leader in several of our businesses, but it also mix- shifted our company to higher growth and higher margin end-markets, reducing our cyclicality and increasing our resilience across all phases of the economic cycle. Looking at our performance metrics since the acquisition underscores the extraordinary performance and commitment of the entire Wesco team. Synergy capture – far exceeded all our initial operational and synergy targets set at the time of the Anixter acquisition. Above-market sales and profit growth – sales increased 30% and adjusted EBITDA increased 89% versus the 2019 performance of the standalone companies, and EBITDA margin expanded 240 basis points. An Award Winning Company Extend Our Industry- Leading Scale and Value Proposition As a leading provider of B2B distribution, logistics services and supply chain solutions, we serve an impressive array of blue-chip customers. We sit in the middle of the value chain between our supplier partners and our customers, putting us in the best position to help them succeed. Our industry-leading value proposition utilizes our scale and expanded portfolio of products, services, and solutions to outperform the market and our competition. We are exceptionally well-positioned to capture the benefits of the ongoing secular growth trends and the increased infrastructure investments in our markets. We are continuing to invest in our core capabilities and execute our cross-sell initiatives to leverage these trends and outperform the market for years to come. Further Develop Our Team and Our Culture of Excellence The tremendous contributions our people are making to our business and in our communities are a testament to our continuous focus on our culture of excellence. Wesco was again recognized for our corporate responsibility and sustainability programs. We were named one of Fortune’s World’s Most Admired Companies again this year with a #2 ranking in the Diversified Wholesalers category. Our company strategy, performance and management were recognized as well. We were named the Best Sustainable Supply Chain Strategy, USA, by Capital Finance International for the second year and to The Drucker Institute’s list of the Best Managed Companies in the World. Wesco was also named Most Innovative B2B Supply Chain Solutions, North America, by Pan Finance magazine for the first time this year. In 2023, we published our new Global Human Rights Principles, formalizing our promise to respect human rights and implement business practices that align with principles outlined by the United Nations Global Compact. Our efforts to support our local communities also continued to grow and our colleagues around the world have increased their engagement. This past year we commemorated our inaugural Day of Caring and celebrated achieving our centennial anniversary goal of 100 new home builds with Habitat for Humanity. We launched our new giving platform that made it easier than ever for employees to volunteer and donate. Since then, our colleagues donated to over 260 organizations and volunteered with more than 50 charities. Our work to prevent injury and promote the health and safety of our employees around the world has continued to earn Wesco a strong reputation. Although one injury is too many, I am pleased to report that our total reportable injury rate (TRIR) for 2023 was 0.50, which is well below the distribution industry benchmark of 1.3. Digitalize and Transform Our B2B Business As a market leader, we expect to benefit from our global capabilities, leading scale, and expanded portfolio of products, services, and supply chain solutions. Our substantial investment and commitment to our digital transformation are expected to magnify those benefits as we roll out that program over the next 36 months. We’re building a new tech stack and digital IT ecosystem that includes best-in-class digital applications, products and services integrated into our proprietary architecture. We have established digital centers of excellence in India and Ireland to support our digital development efforts. Our new front-, middle- and back-office systems use artificial intelligence and machine learning to unlock the power of our big data and improve our business. Our investment in digital technologies and advanced data and analytics is intended to have a multiplying effect on our business and to generate even greater success for our customers and supplier partners.

(“Wesco International”) and its subsidiaries (collectively, “Wesco” or the “Company”), headquartered in Pittsburgh, Pennsylvania, is a leading provider of business-to-business distribution, logistics services and supply chain solutions. We employ approximately 20,000 people, maintain relationships with more than 50,000 suppliers, and serve nearly 150,000 customers worldwide. With millions of products, end-to-end supply chain services, and leading digital capabilities, Wesco provides innovative solutions to meet customer needs across commercial and industrial businesses, contractors, government agencies, educational institutions, telecommunications providers, and utilities. Our innovative value-added solutions include supply chain management, logistics and transportation, procurement, warehousing and inventory management, as well as kitting and labeling, limited assembly of products and installation enhancement. Wesco operates nearly 800 branches, warehouses and sales offices in approximately 50 countries, providing a local presence for customers and a global network to serve multi-location businesses and global corporations. Business Segments and Industry Overview Wesco has operating segments comprising three strategic business units consisting of Electrical & Electronic Solutions (“EES”), Communications & Security Solutions (“CSS”) and Utility & Broadband Solutions (“UBS”). The following is a description of each of our business segments and the industries in which they operate. Electrical & Electronic Solutions The EES segment, with approximately 6,800 employees supporting customers in more than 50 countries, supplies a broad range of products and solutions primarily to the construction, industrial and original equipment manufacturer (“OEM”) markets. Construction and industrial customers include a wide array of contractors, and engineering, procurement and construction firms for industrial, infrastructure, commercial, and data and broadband communications projects. Specific applications include projects for refineries, railways, wastewater treatment facilities, data centers, security installations, offices, and modular and mobile homes. OEM customers require products used in the manufacturing of automotive, industrial, medical, transportation, marine, military and communications equipment. The product portfolio in this business includes a broad range of electrical equipment and supplies, automation and connected devices (the “Internet of Things” or “IoT”), security, lighting, wire and cable, safety, and maintenance, repair and operating (“MRO”) products from industry-leading manufacturing partners. The EES service portfolio includes contractor solutions to improve project execution, direct and indirect manufacturing supply chain optimization programs, lighting and renewables advisory services, and digital and automation solutions to improve safety and productivity. The EES segment operates in highly fragmented markets that include thousands of small, regional and locally-based privately owned competitors, as well as several large, multi-national companies. 2 Communications & Security Solutions The CSS segment, with approximately 4,400 employees supporting customers in more than 50 countries, is a global leader in the network infrastructure and security markets. The network infrastructure market comprises cabling and connectivity, racks and cabinets, power, wireless, and associated products that enable network connectivity and communications in commercial buildings, and hyperscale, cloud-based and multi-tenant data centers. The security market includes video surveillance, fire and intrusion detection, access control, door locking and other solutions that create safe and smart environments for customers. Both the network infrastructure and security businesses are large, fragmented and diverse markets that include various industry groups such as technology, finance, telecommunications service providers, transportation, education, government, healthcare and retail. CSS sells products directly to end-users or through various channels including data communications contractors, security, network, professional audio/visual and systems integrators.

CSS products are often combined with supply chain services to increase efficiency and productivity, including installation enhancement, project deployment, advisory, and IoT and digital services. Utility & Broadband Solutions The UBS segment, with approximately 2,900 employees supporting customers primarily in the U.S. and Canada, provides products and services to investor-owned utilities, public power companies, including municipalities, as well as global service providers, wireless providers, broadband operators and the contractors that service these customers. Investor-owned utility companies provide a combination of electric generation, transmission and/or distribution and are owned by investors or shareholders while public power entities are generally non-profit entities owned by their members or governed by local, state, or municipal governments. These two markets comprise the vast majority of utility customers in the U.S. and Canada. The UBS segment also includes Wesco’s integrated supply business, which provides products and services to large industrial and commercial end-users to support their MRO spend. The products sold into the utility and broadband markets include wire and cable, transformers, transmission and distribution hardware, switches, protective devices, connectors, lighting, conduit, fiber and copper cable, connectivity products, pole line hardware, racks, cabinets, safety and MRO products, and point-to-point wireless devices.

We offer a tuition reimbursement program to eligible employees to encourage the pursuit of undergraduate and graduate education to prepare employees for expanded roles in our business. Our sales and operations development training program has been in place for more than ten years. The program is designed to systematically train and develop new college graduates through on-the-job rotations and cohort learning and development during the first year of employment. Graduates of the program move into various sales and operations roles after completing the one-year program. Additionally, we have a function-specific development program for recent college graduates seeking a career in IT, finance, or supply chain that provides members with eligibility for roles with increasing responsibilities commensurate with their career development goals. Individuals in this program have the opportunity to accelerate the development of their business and technical skills through three 8-month job rotations. We also sponsor a summer internship program to provide college students with work experience within staff or business functions and give them the opportunity to evaluate different career fields. We have developed aco llective approach to deliver personalized, successive development aligned with enterprise needs, known as “Leadership Essentials.” Leadership Essentials consists of separate programs curated for managers that are new to leading people, leaders of teams, or senior leaders. The programs include personalized development journeys which are aligned to both the individual's and the Company's needs. In 2023, Wesco also launched a development campaign to provide specific tools and resources to help leaders across the enterprise support ongoing transformational change. Inclusion and Diversity. Wesco’s focus on inclusion and diversity starts in our boardroom. As of December 31, 2023, Wesco’s Board of Directors was 60% diverse in terms of gender, race or ethnicity. Our inclusion and diversity initiatives extend to all levels of our organization, and we aim to increase the representation of diverse employees through internal promotions, new hires and improved retention, with an inclusion and diversity program that fosters ase nse of individual and group belonging. 7 The objectives of Wesco’s inclusion and diversity program are to 1) leverage the unique experiences and perspectives of our talented workforce to support Wesco’s mission, 2) engage employees and build an inclusive culture, 3) recruit and develop talent that brings new perspectives and thought processes to Wesco, 4) increase representation of suppliers that are owned and operated by teams with diverse backgrounds, and 5) support the communities in which we operate. Wesco’s Global Inclusion and Diversity Council (the “Council”) is led by our Vice President of Inclusion and Diversity and comprises members of senior management who help to ensure that Wesco is making progress toward achieving our program objectives. Wesco has six Business Resource Groups (“BRGs”) to support the following groups: women, BLIPOC (Black, Latino, Indigenous, and People of Color), LGBTQ+, people with diverse abilities, veterans of the armed forces and our early-career employees. These BRGs foster a sense of community and inclusion, provide opportunities to network, support advancement opportunities within the organization, and assist with recruiting. The BRGs are global and open to all employees regardless of any aspect of their personal identity. More than 3,300 employees from around the globe and at every level of the organization have joined one or more of the BRGs. Some of the many benefits of our BRGs include: • • • • Supporting our business initiatives; Creating a more inclusive work environment; Providing opportunities for employee development, education, training, recruitment, retention, and business outreach and development; and Supporting innovation by providing insights into new markets, product development, and multicultural marketing. Wesco has also established a diverse leadership program for the purpose of promoting the development of our diverse emerging leaders and providing direction for career advancement through exposure to new opportunities. Company Ethics. We are firmly committed to operating with the highest level of ethics and integrity. This commitment is reflected in our Code of Business Conduct, which applies to our Directors, officers, employees and other parties when they are acting on behalf of Wesco. Annually, employees must acknowledge that they have received, read and will comply with the Code of Business Conduct. Our global Ethics and Compliance program provides employees with the tools they need to understand our expectations for ethical business conduct. It also provides an anonymous reporting channel for employees and outside parties to report issues of concern regarding workplace activities or business practices without fear of retaliation. Compensation and Benefits Program. Wesco provides competitive compensation and benefits packages in our locations around the globe. In the U.S., we provide a comprehensive benefits program that offers choices to fit our employees’ diverse needs including health and disability benefits, paid time off (including a self-managed time off policy for certain eligible employees), life insurance, retirement programs, and access to other services that support health and wellness. To further improve the health of our employees, we offer a variety of activities and programs that assist our employees and their family members to better manage or overcome major well-being challenges, including an employee assistance program, wellness coaching, case/disease management and wellness discounts. Employee Engagement. We believe that employee engagement is not only good for our people; it also benefits various aspects of our business, from safety to improved productivity and customer service. Wesco regularly surveys employees to assess their engagement, as well as to solicit feedback and ideas on organizational changes, so senior management may more intelligently adjust to our employees’ evolving needs and support employee success. Wesco also promotes employee engagement through regular town hall discussions. Community. Wesco has established relationships with several charitable organizations and encourages employees to volunteer in the community by providing one day of paid volunteer time off per year. By connecting with and contributing to local charitable organizations, Wesco supports the development of strong, vibrant and diverse communities. Wesco Cares is our corporate philanthropy program focused on affordable housing and humanitarian aid and provides for corporate charitable donations, employee volunteerism, and employee gift-matching. In 2023, June 22nd became an annual day of caring for Wesco employees globally on which employees are encouraged to volunteer in their communities. 8 Environmental Management Environmental sustainability is a priority for Wesco. We strive to continually improve our environmental management by establishing and working towards various sustainability objectives. We leverage our environmental management experience in our offerings of products and services to our customers. The foundation of our environmental management is our Global Environmental, Health, Safety and Sustainability Policy, which aligns with key provisions of the ISO 14001:2015 environmental management standards. The policy includes clear management accountability for environmental sustainability, direct program responsibilities, key performance indicators and other metrics to track progress. We produce a Sustainability Report annually which is made public on our website. Information contained in the Sustainability Report is not part of, and should not be construed as being incorporated by reference into, this Annual Report on Form 10-K. We are working to reduce our environmental impact in the following areas: Energy. The vast majority of the energy we use is for lighting, heating, and cooling our nearly 800 branches, warehouses, and sales offices in approximately 50 countries around the world. Where practicable, we engage with the owners and agents of the buildings we lease to improve energy efficiency, and we include energy-efficiency requirements in new building leases. We have implemented lighting retrofit projects, identified participation plans to purchase green power through utility green tariffs, and installed solar systems at certain facilities. Adding to our energy consumption is a fleet of approximately 1,300 trucks and 1,700 cars for our distribution and sales activities. Our Fleet Efficiency Policy includes the use of fuel-efficient vehicles, determining the most efficient routes, and idling restrictions. Emissions. Our main source of direct and indirect GHG emissions from our own activities is attributed to the power and natural gas used by our facilities, which accounts for approximately 70% of total emissions from our own activities. As such, the energy efficiency of our buildings is a key focus of our emissions-reduction activities. A secondary source of our GHG emissions is our truck and car fleet, and part of our emissions is due to corporate travel and the lifecycle impact of our landfilled waste. We have implemented policies and technology to reduce the emissions impact of our fleet, which included evaluation of alternative fuel sources and an assessment of electric vehicle integration into our truck and sales fleet. We have a goal to reduce absolute direct and certain indirect GHG emissions by 30% from a 2021 baseline by 2030. Climate Impact. Wesco aligns with the Task Force on Climate-Related Financial Disclosures (“TCFD”) framework. We annually review environmental programs, policies, and data, including energy consumption and GHG emissions to identify and assess climate-related risks. The Board of Directors oversees the integration of ESG principles throughout our enterprise. This includes oversight of enterprise risk. Our Board of Directors receives regular updates and ongoing information on significant risks and risk mitigation plans. Our ESG management team also reports to the Board of Directors annually on the status of our ESG programs and progress on achieving sustainability goals. We have identified climate-related opportunities that include expanding our offering of energy-efficient and renewable energy products. As attention and interest grow for climate mitigation solutions, we believe that Wesco is well positioned to expand our business in these energy efficiency and renewable energy technologies and projects. Waste. Our top three waste streams are cardboard, wood pallets and reels, and plastic. We strive to reduce these waste streams by applying Lean principles and identifying opportunities for reuse and recycling. We have developed regional relationships with recycling vendors that recycle non-traditional waste streams, specifically metal and wood. We have a goal to reduce landfill waste intensity by 15% across our U.S. and Canadian locations from a 2020 baseline by 2030. Water. As a distributor and supply chain solutions provider, we are not a major consumer of water. Our facilities primarily use water for sanitation, cleaning, and irrigation purposes. We track water usage at our locations and use the data to identify unusual consumption patterns that could indicate undetected leaks or excessive usage that requires intervention. Intellectual Property We work to protect our intellectual property through a combination of trademarks, patents and trade secrets, applicable intellectual property laws, confidentiality procedures and contractual provisions. We currently have trademarks, patents and service marks registered with the U.S. Patent and Trademark Office and in various other countries. The “Wesco” and “Anixter” trademarks and service marks are registered in the U.S. and various foreign jurisdictions, and the “EECOL” service mark is 9 registered in Canada. The trademarks and service marks filed in the U.S. include, among others: “Wesco®” and our corporate logo. We have also applied to register international trademarks, patents, and service mark applications in various foreign jurisdictions. While our patents have value, none is so essential that its loss would materially affect our business. Environmental Matters Our facilities and operations are subject to federal, state and local laws and regulations relating to environmental protection and human health and safety. Some of these laws and regulations may impose strict, joint and several liabilities on certain persons for the cost of investigation or remediation of contaminated properties. These persons may include former, current or future owners or operators of properties and persons who arranged for the disposal of hazardous substances. Our owned and leased real property may give rise to such investigation, remediation and monitoring liabilities under environmental laws. In addition, anyone disposing of certain products we distribute, such as ballasts, fluorescent lighting and batteries, must comply with environmental laws that regulate certain materials in these products. We believe that we are in compliance, in all material respects, with applicable environmental laws. As a result, we do not anticipate making significant capital expenditures for environmental control matters either in the current year or in the near future. Seasonality Our operating results are not significantly affected by seasonal factors. Sales during the first and fourth quarters have historically been affected by a reduced level of activity due to the impact of weather on projects. Sales typically increase beginning in March, with slight fluctuations per month through October. During periods of economic expansion or contraction, our sales by quarter have varied significantly from this pattern. Website Access Our Internet address is www.wesco.com. Information contained on our website is not part of, and should not be construed as being incorporated by reference into, this Annual Report on Form 10-K.

In addition, the charters for our Audit, Compensation, Executive and Nominating and Governance committees, as well as our Corporate Governance Guidelines, Code of Principles for Senior Executives, Independence Policy, Global Antibribery and Anticorruption Policy, and Code of Business Conduct for our Directors, officers and employees, are all available on our website at the “Leadership” link under the “Our Company” heading. Forward-Looking Information This Annual Report on Form 10-K contains various “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These statements involve certain unknown risks and uncertainties, including, among others, those contained in Item 1, “Business,” Item 1A, “Risk Factors,” and Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” When used in this Annual Report on Form 10-K, the words “anticipates,” “plans,” “believes,” “estimates,” “intends,” “expects,” “projects,” “will” and similar expressions may identify forward-looking statements, although not all forward-looking statements contain such words.

The following factors, among others, could cause our actual results to differ materially from the forward-looking statements we make. All forward-looking statements attributable to us or persons working on our behalf are expressly qualified by the following factors. This information should be read in conjunction with Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations”, Item 7A, “Quantitative and Qualitative Disclosures about Market Risks” and the consolidated financial statements and related notes included in this Form 10-K. Risks Related to the Global Macroeconomic Environment and Our International Operations Adverse conditions in the global economy and disruptions of financial and commodities markets could negatively impact us and our customers. Our results of operations are affected by the level of business activity of our customers, which in turn is affected by global economic conditions and market factors impacting the industries and markets that they serve. Certain global economies and the financial and commodities markets continue to experience significant uncertainty and volatility. Adverse economic conditions, disruptions in financial markets or lack of liquidity in these markets, particularly in North America, including those caused by political risk or instability, may adversely affect our revenues and operating results. Disruptions in financial markets can cause increases in interest rates and borrowing costs. Economic and financial market conditions may also affect the availability or the cost of financing for projects and for our customers' capital or other expenditures, which can result in project delays or cancellations and thus affect demand for our products. There can be no assurance that any governmental responses to economic conditions or disruptions in the financial markets ultimately will stabilize the markets or increase our customers' liquidity or the availability of credit for us or our customers. Although no single customer accounts for more than 2% of our sales, a payment default by one of our larger customers could have a negative short-term impact on earnings or liquidity. A financial or industry downturn could have an adverse effect on the collectability of our accounts receivable, which could result in longer payment cycles, increased collection costs and defaults, and limit our ability to borrow additional funds. Should one or more of our larger customers declare bankruptcy, it could adversely affect the collectability of our accounts receivable, along with credit loss reserves and net income. In addition, our ability to access the capital markets may be restricted at a time when we would like, or need, to do so. The economic, political and financial environment may also affect our business and financial condition in ways that we currently cannot predict. The Russia-Ukraine and Middle East conflicts, and resulting international responses, have contributed to further volatility and uncertainty in the global financial and commodities markets, resulting in fluctuations in oil and commodity prices. There can be no assurance that economic and political instability, both domestically and internationally (for example, resulting from the Russia-Ukraine or Middle East conflicts, changes in the creditworthiness of the U.S. or any government, changes to economic or trade policies, sanctions, tariffs or participation in trade agreements or economic and political unions) will not adversely affect our results of operations, cash flows or financial position in the future. Our global operations expose us to political, economic, legal, currency and other risks. We operate a network of nearly 800 branches, warehouses and sales offices with operations in approximately 50 countries. Approximately one-third of our employee population are non-U.S. employees. We derive approximately 26% of our revenues from sales outside of the U.S. As a result, we are subject to additional risks associated with owning and operating businesses in these foreign markets and jurisdictions. Operating in the global marketplace exposes us to a number of risks including: • • • • geopolitical and security issues, including armed conflict and civil or military unrest (such as the evolving Russia- Ukraine and Middle East conflicts), political instability, terrorist activity and human rights concerns; natural disasters (including as a result of climate change) and public health crises (including pandemics such as COVID- 19), and other catastrophic events; global supply chain disruptions and large-scale outages or inefficient provision of services from utilities, transportation, data hosting, or telecommunications providers; abrupt changes in government policies, laws, regulations or treaties, including imposition of export, import, or doing- business regulations, trade sanctions, embargoes or other trade restrictions (such as sanctions and other restrictions 13 imposed against Russia in response to the Russia-Ukraine conflict, as well as those against China to mitigate the potential U.S. national security concerns related to critical infrastructure and technology); • • • tax or tariff increases; government restrictions on, or nationalization of, our operations in any country; changes in labor conditions and difficulties in staffing and managing international operations, including logistical and communication challenges; challenges in protecting our IP rights in certain countries; • monetary policy of the countries where we operate and related currency exchange rate fluctuations; • • • • local business and cultural factors that differ from our current standards and practices; other social, political and economic instability, including recessions and other economic crises in other regions. continuing uncertainty regarding social, political, immigration, and tax and trade policies in the U.S. and abroad; and In response to the Russia-Ukraine conflict, the United States, the European Union and other governments throughout the world imposed broad economic sanctions and other restrictions against Russia and Russian interests. In October 2023, Hamas militants attacked Israel, leading Israel to respond with air strikes and a major ground operation in Gaza. To the extent the Russia- Ukraine and Middle East conflicts escalate or are further prolonged, it may have the effect of heightening many of the risks described above or elsewhere in these risk factors. Our business and operations have been and may continue to be adversely affected by the COVID-19 pandemic, and the duration and extent to which COVID variants or other pandemics will affect our business, financial condition, results of operations, cash flows, liquidity, and stock price remains uncertain. The global COVID-19 pandemic created significant disruption to the broader economies, financial markets, workforces, business environment and supply chains, as well as to our suppliers and customers. Beginning in 2020, the pandemic caused significant disruptions to our business due to, among other things, disruptions to our suppliers and global supply chain, labor shortages, transportation disruptions, travel restrictions, the impact on our customers and their demand for our products and services and ability to pay for them, as well as temporary closures of facilities. Some of the actions we have taken in response to the COVID-19 pandemic, such as implementing remote working arrangements, may also create increased vulnerability to cybersecurity incidents and other risks. Remote working arrangements and the decrease in commercial office occupancy rates may adversely affect sectors of the economy or the bank or financial markets, which may affect our customers or lenders, or may increase market volatility. The full extent to which new COVID variants or new pandemics may impact our business, results of operations, and financial condition depends on many evolving factors and future developments for which there remains significant uncertainty; the availability, effectiveness and public acceptance of treatments or vaccines (including boosters); the impact of the imposition of governmental actions; and the impact of pandemics on the global supply chain and the broader economy and capital markets, as well as the matters noted above. In addition, COVID variants and other pandemics may adversely affect many of our suppliers’ and customers' businesses and operations, including the ability of our suppliers to manufacture or obtain the products we sell or to meet delivery requirements and commitments, and our customers’ demand for our products and services and the ability to pay for them, all of which could adversely affect our sales and results of operations. We may not be able to appropriately respond to or manage the impact of these events, and any of these events could materially adversely affect our business, financial condition, results of operations, cash flows, liquidity and stock price. We are subject to various laws and regulations globally and any failure to comply could adversely affect our business. We are subject to a broad range of laws and regulations in the jurisdictions where we operate globally, including, among others, those relating to data privacy and protection, cyber security, import and export requirements, anti-bribery and corruption, product compliance, supplier regulations regarding the sources of supplies or products, sustainability and environmental protection, health and safety requirements, intellectual property, foreign exchange controls and cash repatriation restrictions, labor and employment, human rights, e-commerce, advertising and marketing, anti-competition, artificial intelligence and tax. Compliance with these domestic and foreign laws, regulations and requirements may be burdensome, increasing our cost of compliance and doing business. In addition, as a supplier to federal, state, and local government agencies, we must comply with certain laws and regulations relating specifically to our governmental contracts. Although we have implemented policies and procedures designed to facilitate compliance with various laws, we cannot assure you that our employees, contractors, or agents 14 will not violate such laws and regulations, or our policies and procedures. Any such violations could result in the imposition of fines and penalties, damage to our reputation, and, in the case of laws and regulations relating to governmental contracts, the loss of those contracts. Fluctuations in foreign currency have an effect on our results from operations. The results of certain of our foreign operations are reported in the local currency and then translated into U.S. dollars at the applicable exchange rates for inclusion in our consolidated financial statements. The exchange rates between some of these currencies and the U.S. dollar have fluctuated significantly in recent years (particularly the Argentine Peso and the Egyptian Pound), and may continue to do so in the future. We may incur losses related to foreign currency fluctuations, and foreign exchange controls may prevent us from repatriating cash in countries outside the U.S. In addition, because our financial statements are stated in U.S. dollars, such fluctuations may also affect the comparability of our results between financial periods. Risks Related to Our Strategic Initiatives and Acquisitions Expansion into new business activities, industries, product lines or geographic areas could subject the Company to increased costs and risks and may not achieve the intended results. We have invested significantly in expanding our digital solutions and digitalization initiatives, including but not limited to, e- commerce capabilities, enhancing the online customer experience, software as a service (SaaS), internet of things (IoT) technology, electrification, automation, grid modernization, security, smart building technology and advisory services. If our efforts to expand our digital and service capabilities are not successful, we may not realize the return on our investments as anticipated, or our operating results could be adversely affected by slower than expected sales growth or additional costs. Furthermore, engaging in or significantly expanding business activities in product sourcing, sales and services could subject the Company to unexpected costs and risks. Such activities could subject us to increased operating costs, product liability, regulatory requirements and reputational risks. Our expansion into new and existing markets, including manufacturing related or regulated businesses, may present competitive distribution and regulatory challenges that differ from current ones. We may be less familiar with the target customers and may face different or additional risks, as well as increased or unexpected costs, compared to existing operations. Growth into new markets may also bring us into direct competition with companies with whom we have little or no past experience as competitors. To the extent we are reliant upon expansion into new geographic, industry and product markets for growth and do not meet the new challenges posed by such expansion, our future sales growth could be negatively impacted, our operating costs could increase, and our business operations and financial results could be negatively affected. Our strategic and operational initiatives, including our digital transformation initiatives, are subject to various risks and uncertainties, and we may be unable to implement the initiatives successfully. We are engaged in a number of strategic and operational initiatives, including our digital transformation initiatives, designed to optimize costs and improve operational efficiency. Our ability to successfully execute these initiatives is subject to various risks and uncertainties and there can be no assurance regarding the timing of or extent to which we will realize the anticipated benefits, if at all. We may not be able to fully realize the anticipated benefits and cost savings of mergers and acquisitions. In 2020, we completed our merger with Anixter and in 2022, we completed the acquisition of Rahi Systems. We consider and may pursue other acquisitions on an on-going basis. The success of these and future acquisitions, including anticipated benefits and cost savings, depends on the successful combination and integration of the companies’ businesses. It is possible that the integration process of an acquired business could result in the loss of key employees, higher than expected costs, diversion of management attention, the disruption of either company’s ongoing legacy businesses or inconsistencies in standards, controls, procedures and policies that adversely affect the Company’s ability to maintain relationships with customers, suppliers and employees or to achieve the anticipated benefits and cost savings of the transaction. We have incurred, and expect to continue to incur, a number of non-recurring costs associated with recent acquisitions and related integration activities. This includes transaction fees and expenses related to formulating and implementing integration plans, including facilities, systems consolidation and employment-related costs. We continue to assess the magnitude of these costs, and additional unanticipated costs may be incurred in the integration of the acquired companies’ businesses. Although we 15 anticipate that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, should allow us to offset integration-related costs over time, this net benefit may not be achieved in the near term, or at all. If we experience difficulties with the integration process, the anticipated benefits of recent or future mergers or acquisitions may not be realized or may take longer to realize than expected. These integration matters could have an adverse effect on us for an undetermined period. Any future acquisitions that we may undertake will involve a number of inherent risks, any of which could cause us not to realize the anticipated benefits. We have expanded our operations through organic growth and selected acquisitions of businesses and assets, such as our acquisition of Rahi Systems in 2022, and may seek to do so in the future. Acquisitions involve various inherent risks, including: problems that could arise from the integration of the acquired business; uncertainties in assessing the value, strengths, weaknesses, contingent and other liabilities and potential profitability of acquisition candidates; the potential loss of key employees of an acquired business; the ability to achieve identified operating and financial synergies anticipated to result from an acquisition or other transaction; unanticipated changes in business, industry or general economic conditions that affect the assumptions underlying the acquisition or other transaction rationale; and expansion into new countries or geographic markets where we may be less familiar with operating requirements, target customers and regulatory compliance. Any one or more of these factors could increase our costs or cause us not to realize the benefits anticipated to result from the acquisition of a business or assets. Risks Related to Our Information Systems and Technology and Intellectual Property Any significant disruption or failure of our information systems could lead to interruptions in our operations, which may materially adversely affect our business operations, financial condition, and results of operations. We operate a number of facilities and we coordinate company activities, including information technology systems, administrative services, and similar systems, through our headquarters operations. We rely on the proper functioning and availability of our information systems to successfully operate our business, including managing inventory, processing customer orders, shipping products, providing service to customers, maintaining customer and supplier information, and compiling financial results. Our operations depend on our ability to maintain existing systems and implement new technology, which includes allocating sufficient resources to upgrade our information technology systems, and to protect our equipment and the information stored in our databases against both man-made and natural disasters (including those as a result of climate change), as well as power losses, computer and telecommunications failures, technological breakdowns, unauthorized intrusions, cyber- attacks, and other events. Further, many of the products and services we provide to customers rely on information technology to transmit and store data in Company, cloud-based and third-party systems. Even where Company-managed information systems remain fully operational, a failure by a third-party's systems or procedures could have negative effects on our operations. Any significant or prolonged unavailability or failure of critical information systems could materially impair our ability to maintain proper levels of inventories, process orders, meet the demands of our customers and suppliers in a timely manner, and other harmful effects on our business operations, which could negatively affect our financial results. We may not be able to realize the anticipated benefits and cost savings of our digital transformation initiatives or enhancing existing, and deploying new, technology, digital products and information systems in our operations. We are executing our digital transformation strategy and seek to continually enhance existing and deploy new technology, digital products and information systems as a part of our technology-enablement strategy. Such changes could fail to realize anticipated benefits, create new liability or disrupt our existing information systems or other aspects of our operations. Conversions to new information technology systems may result in cost overruns, delays or business interruptions. Efforts to align portions of our business on common enterprise platforms, systems and processes could result in unforeseen interruptions, increased costs or liability, and other negative effects. Sales enablement initiatives that improve data analytics and automate, optimize, digitize or outsource tasks could result in unforeseen consequences, including our ability to process orders, receive and ship products, maintain inventories, collect accounts receivable and pay expenses, therefore impacting our results of operations. Additionally, exploring and deploying use cases for artificial intelligence, generative artificial intelligence and large language models to empower our employees and streamline our operations may introduce new risks such as biased output, inaccurate output, security vulnerabilities and increased stakeholder or regulatory scrutiny, which could impact the integrity of our business 16 processes, expose us to litigation or fines, or erode the trust of our stakeholders. If our technology systems are disrupted, become obsolete or do not adequately support our strategic, operational or compliance needs, or if the controls placed over the use of new and existing technology prove inadequate, it could result in a competitive disadvantage or adversely affect our business operations, reputation or financial condition. Our business depends on cloud-based services operated by various third-party service providers, and any disruption in or interference with our use of these services could have adverse effects on our business, operational results, and financial condition. We rely heavily on cloud-based services, systems and networks operated or supported by various third-party service providers to operate critical business systems, to process, transmit and store information, and to conduct our business activities and transactions with employees, customers, vendors and other third parties. Our utilization of these cloud-based services and systems will increase as we continue to implement our digital transformation initiatives. This reliance makes us vulnerable to service malfunctions, interruptions, or outages caused by technical failures, natural disasters, or cybersecurity and other security breaches. Such disruptions can adversely impact our operations as well as our ability to serve our customers, diminishing customer satisfaction and potentially damaging our business reputation. Moreover, we have limited control over these third-party providers and the need to manage multiple external service providers increases operational complexity. If any of our cloud service providers do not perform effectively, or if we fail to adequately monitor their performance (including their failure to comply with service- level agreements or regulatory requirements), we could incur additional expenses to remediate errors made by such providers, or could be subject to litigation, claims or regulatory investigations and actions. In addition, our third-party service providers might unilaterally discontinue or limit our access to services, increase pricing, alter service terms, or seek to terminate their contractual relationship with us, negatively affecting our operations. The failure to maintain our relationships or renew our contracts with cloud service providers on commercially favorable terms could pose serious challenges to our business. Although we could seek alternative providers, we may incur significant costs in connection with the transition or experience operational disruptions. In light of these factors, the cumulative impact of such issues, whether service disruptions, regulatory challenges, litigation or remediation costs, reputational harm, or cost escalations, could pose substantial risks to our operational efficiency and our ability to meet our strategic objectives, thereby potentially leading to material adverse effects on our overall business performance and financial results. We may experience a failure in or breach of our information security systems, or those of our third-party product suppliers or service providers, as a result of cyber-attacks or information security breaches. Because we rely heavily on information technology both in serving our customers and in our enterprise infrastructure in order to achieve our objectives, we may be vulnerable to damage or intrusion from a variety of cyber-attacks, including computer viruses, ransomware, worms or other malicious software programs that seek to gain to access our systems and networks, or those of our third-party service providers. Additionally, third parties may fraudulently attempt to induce employees or customers into disclosing sensitive information such as user names, passwords and other information in order to gain access to our customers’ data or our data, including our intellectual property and other confidential business information, or our information technology systems. Information technology security threats to our systems, networks and data have dramatically increased in recent years due to the proliferation of new technologies and the increased sophistication and activities of perpetrators. We have seen, and will continue to see, industry-wide vulnerabilities, which could cause widespread disruptions to our or other parties' systems. In addition, the risk of retaliatory cyber-attacks has increased as a result of geopolitical conflicts, including the Middle East and Russia-Ukraine conflicts. These threats and vulnerabilities pose a risk to the security of our systems and networks and the confidentiality, availability and integrity of our proprietary and confidential information. Although we actively manage information technology security risks within our control and continually seek to enhance our controls and processes designed to protect our systems, computers, networks and data, there can be no assurance that such actions will be sufficient to mitigate all potential risks. As cyber threats continue to evolve, we may be required to expend additional resources to continue to enhance our information security measures and remediate any information security vulnerabilities. Despite the precautions we take to mitigate the risks of such events, an attack on our enterprise information technology system, or those of third parties with which we do business, could result in theft or unauthorized disclosure of our proprietary or confidential information or a breach of confidential customer, supplier or employee information. Such events could impair our ability to conduct our operations or cause disruptions to our supply chain, which could have an adverse impact on revenue and 17 harm our reputation. Additionally, such an event could expose us to regulatory sanctions or penalties, lawsuits or other legal action or cause us to incur legal liabilities and costs, which could be significant, in order to address and remediate the effects of an attack and related security concerns. The insurance coverage we maintain may be inadequate to cover claims or liabilities relating to a cybersecurity attack. In addition, the legal and regulatory environment surrounding information security and privacy in the U.S. and international jurisdictions is constantly evolving and additional laws and regulations regarding artificial intelligence are being considered and implemented. Violation or non-compliance with any of these laws or regulations, contractual requirements relating to data security and privacy, or our own privacy and security policies, either intentionally or unintentionally, or through the acts of intermediaries could have a material adverse effect on our brand, reputation, business, financial condition and results of operations, as well as subject us to significant fines, litigation losses, third-party damages and other liabilities. We could incur significant and unexpected costs in our efforts to successfully avoid, manage, defend and litigate intellectual property matters. We rely on certain trademarks, patents, trade secrets, copyrights, and other intellectual property, and are continuing to develop intellectual property in connection with the digital transformation of our business and operations. We cannot be certain that others have not or will not infringe upon our intellectual property, or that in-house or third-party solutions, including the output of large language models, will not potentially infringe upon the intellectual property rights of others. Intellectual property litigation could be costly and time consuming, and we could incur significant legal expenses pursuing these claims against others. From time to time, we may receive notices from third parties that allege intellectual property infringement. Any dispute or litigation involving intellectual property could be costly and time-consuming due to its complexity and uncertainty. Our intellectual property portfolio may not be useful in asserting a counterclaim or negotiating a license in response to aclai m of infringement or misappropriation. In addition, as a result of such claims, we may lose our rights to utilize critical technology or may be required to pay substantial damages or license fees with respect to infringed rights or be required to redesign or restructure our products or services at a substantial cost, any of which could negatively impact our operating results. Risks Related to Our Industry, Markets and Business Operations Loss of key suppliers could decrease sales, profit margins and earnings. Most of our agreements with suppliers are terminable by either party on 60 days' notice or less for any reason. We currently source products from thousands of suppliers. However, our 10 largest suppliers in 2023 accounted for approximately 27% of our purchases by dollar volume for the period. The loss of, or a substantial decrease in the availability of, products from any of these suppliers, asuppl ier's change in sales strategy to reduce its reliance on distribution channels, the loss of key preferred supplier agreements, or disruptions in a key supplier's operations could have ama terial adverse effect on our business. Although we believe our relationships with our key suppliers are good, they could change their strategies as aresult of a change in control, expansion of their direct sales force, changes in the marketplace or other factors beyond our control, including a key supplier becoming financially distressed which could materially affect our supply chain, increase our costs or disrupt our ability to deliver products to our customers in atim ely and cost-effective manner. We have been and may continue to be adversely affected by supply chain challenges, including product shortages, delays and price increases, which could decrease sales, profit margins and earnings. Supply interruptions could arise from shortages of raw materials, effects of economic, political or financial market conditions on a supplier's operations, labor disputes or weather conditions affecting products or shipments, transportation disruptions, natural disasters, outbreaks of disease, information system disruptions or other reasons beyond our control. Since the start of the COVID-19 pandemic, our industry and the broader economy experienced supply chain challenges, including shortages in raw materials and components, labor shortages and transportation constraints, leading to product delays, backlogged orders, increased transportation cost and longer lead times. In 2023, we saw varying degrees of supply chain improvements, with manufacturers adjusting their production footprints through diversification, reshoring, nearshoring and other strategies designed at mitigating supply chain risks, alongside continued volatility in the availability of certain raw materials, components and products. While we continue to aggressively and proactively manage supply chain developments, we have experienced, and may continue to experience, some delays in receiving products from our suppliers. We cannot be certain that 18 particular products will be available to us, or available in quantities sufficient to meet customer demand. Any product shortages and delays could impair our ability to make scheduled deliveries to our customers in a timely manner and cause us to be at a competitive disadvantage. Product shortages and delays in deliveries, along with other factors such as price inflation and higher transportation costs, could result in price increases from our suppliers. We may be unable to pass these price increases on to our customers, which could erode our profit margins. Supply chain constraints, increased product costs and inflationary pressures could continue or escalate in the future, for example if the Russia-Ukraine, Middle East and other geopolitical conflicts escalate or are further prolonged, which would have an adverse impact on our business and results of operations. We conducted a climate risk assessment in 2022 aligned to the Task Force on Climate-Related Financial Disclosures (“TCFD”) to determine the materiality of climate-related risks to our business. The effects of global climate change could increase the frequency and intensity of natural disasters or extreme weather conditions, such as tropical storms, severe winter weather, drought, flooding, heat waves, wildfires and rising sea levels, which could cause or exacerbate supply chain interruptions. For example, some of our customers’, suppliers’ and our operations are in water-stressed regions or areas prone to flooding or wildfires, and our facilities depend on power grids that may be impacted by severe weather. With global climate change increasing the frequency and severity of such events, it is possible that we could face greater climate-related risks in the future, which could result in temporary or prolonged interruptions in operations, increase our operating costs and capital expenditures, and reduce revenue and profitability. The profitability of our business is also dependent upon the efficiency of our supply chain. An inefficient or ineffective supply chain strategy or operations could increase operational costs, decrease sales, profit margins and earnings, which could adversely affect our business. Product cost fluctuations could decrease sales, profit margins and earnings. Some of our products, such as wire and conduit, are commodity price based products and may be subject to significant price fluctuations which are beyond our control. Recently, we have experienced fluctuations in commodity costs, as well as in the costs of raw materials and components generally, as a result of global economic conditions and other trends. Increases in these costs could erode our profit margin and negatively impact our results of operations to the extent we are unable to successfully mitigate and offset the impact of these costs. While increases in the cost of energy or products could have adverse effects, decreases in those costs, particularly if severe, could also adversely impact us by creating deflation in selling prices, which could cause our profit margin to deteriorate. Fluctuations in energy or raw materials costs can also adversely affect our customers. Challenges in managing working capital and inventory in response to evolving customer demands, supply chain disruptions, and market fluctuations could significantly impact our cash flow, profit margins, and overall business performance. Our ability to manage our working capital, including our inventory position, as well as efficiently managing our receivables and payables, is important to the successful operation of our business and resulting cash flow, and if we do not manage our working capital adequately, it can affect our cash flows, results of operations, and financial performance. Evolving customer demand patterns and supply chain disruptions may require rapid adjustments in inventory management strategies. Additionally, our business may continue to adjust the proportion of direct ship sales versus stock sales. An increase in direct ship sales could negatively impact product margins and other financial metrics, while an increase in stock sales could negatively impact inventory carrying costs and free cash flow, either of which could have a negative impact on our business and financial performance. Furthermore, fluctuations in foreign exchange rates, particularly in international markets, combined with varying interest rates, can significantly affect the cost of inventory, the value of receivables, and the cost of debt, thereby impacting our working capital efficiency, ability to fund growth initiatives and overall financial stability. A decline in project volume could adversely affect our sales and earnings. While much of our sales and earnings are generated by comparatively smaller and more frequent orders, the fulfillment of large orders for large capital projects generates significant sales and earnings. Accordingly, our results of operations can fluctuate depending on whether and when large project awards occur and the commencement and progress of work under large contracts already awarded. 19 The awarding and timing of projects is unpredictable and depends on many factors outside of our control. Project awards often involve complex and lengthy negotiations and competitive bidding processes. These processes can be impacted by a wide range of factors including a customer’s decision to not proceed with a project or its inability to obtain necessary governmental approvals or financing, commodity prices, and overall market and economic conditions. Slow macro-economic growth rates, difficult credit market conditions for our customers, weak demand for our customers’ products or other customer spending constraints can result in project delays or cancellations. In addition, some our competitors may also be more willing to take greater or unusual risks or include terms and conditions in a contract that we might not deem acceptable. We have risks associated with the sale of nonconforming products and services. Historically, we have experienced a small number of cases in which our vendors supplied us with products that did not conform to the agreed upon specifications without our knowledge. Additionally, we may inadvertently sell a product not suitable for a customer’s application. We address this risk through our quality control processes, by seeking to limit liability and our warranty in our customer contracts, and by obtaining indemnification rights from vendors. However, there can be no assurance that we will be able to include protective provisions in all of our contracts or that vendors will have the financial capability to fulfill their indemnification obligations to us. Disruptions to our logistics capability, or our failure to effectively manage supply chain logistics during periods of disruption, may have an adverse impact on our operations. Our global logistics services are operated through distribution centers around the world. An interruption of operations at any of our distribution centers could have a material adverse effect on the operations of branches served by the affected distribution center. Such disaster related risks and effects are not predictable with certainty and, although they typically can be mitigated, they cannot be eliminated. We seek to mitigate our exposures to disaster events in a number of ways. For example, where feasible, we design the configuration of our facilities to reduce the consequences of disasters. We also maintain insurance for our facilities against casualties, and we evaluate our risks and develop contingency plans for dealing with them. Disruptions to our logistics capability or supply chain may have an adverse impact on ability to serve our customers, based on factors such as a lack of depth and breadth in the suppliers we do business with, failure to utilize and optimize warehouse space availability in key markets, failure to achieve network optimization and last mile solutions, and failure to improve our supply chain resiliency through technological improvements. Although we have reviewed and analyzed a broad range of risks applicable to our business, the risks that most significantly affect us may not be those that we have concluded are most likely to occur. Furthermore, although our reviews have led to more systematic business continuity and contingency planning, our plans are in varying stages of development and execution, such that they may not be adequate at the time of occurrence for the magnitude of any particular disaster event that we may encounter. We also depend on transportation service providers for the delivery of products to our customers. Any significant interruption or disruption in service at one or more of our distribution centers due to severe weather or natural disasters (including as a result of climate change), information technology upgrades, operating issues, disruptions to our transportation network, public heath crises, pandemics, or other unanticipated events, could impair our ability to obtain or deliver inventory in ati mely manner, increase transportation costs, cause cancellations or delays in shipments to customers or otherwise disrupt our normal business operations. Our reliance on third-party service providers for outsourced functions could negatively impact our reputation, operations or financial results. We engage third-party suppliers for various outsourced services. This approach aims to enhance efficiency and generate cost savings. However, it also increases our operational complexity and reduces our direct control over these functions. Dependence on these providers subjects us to risks such as inadequate service levels, untimely support, non-compliance with legal requirements and industry standards, and potential disruptions if these relationships are terminated or not renewed. These factors could lead to missed deadlines, reputational harm, or challenges in adapting to regulatory or market changes. In the event of substandard performance by our service providers, or if we are unable to promptly replace them with competent alternatives, our business, reputation, and financial condition could be adversely affected. We may consider outsourcing additional functions in the future, further heightening these risks. 20 An increase in competition could decrease sales, profit margins, and earnings. We operate in a highly competitive industry and compete directly with global, national, regional and local providers of like products and services. Some of our existing competitors have, and new market entrants may have, greater resources than us. Competition is generally based on product line breadth, product availability, service capabilities and price. Other sources of competition are buying groups formed by smaller distributors to increase purchasing power and provide some cooperative marketing capability, as well as e-commerce companies. There may be new market entrants with non-traditional business and customer service models, resulting in increased competition and changing industry dynamics. Existing or future competitors may seek to gain or retain market share by reducing prices, and we may be required to lower our prices or may lose business, which could adversely affect our financial results. We may be subject to supplier price increases while not being able to increase prices to customers. Also, to the extent that we do not meet changing customer preferences or demands, or to the extent that one or more of our competitors becomes more successful with private label products, on-line offerings or otherwise, our ability to attract and retain customers could be materially adversely affected. Existing or future competitors also may seek to compete with us for acquisitions, which could have the effect of increasing the price and reducing the number of suitable acquisitions. These factors, in addition to competitive pressures resulting from the fragmented nature of our industry, could affect our sales, profit margins and earnings. Our continued success may depend on our ability to execute environmental, social and governance (“ESG”) programs as planned and may impact our reputation and operating costs. Customers, suppliers, employees, community partners, shareholders and regulatory agencies in various jurisdictions globally are increasingly requesting disclosure and action relating to ESG objectives and performance. We commit time and resources to ESG efforts, consistent with our corporate values and in ways designed to strengthen our business, including programs focused on sustainability, corporate responsibility, human rights, ethics, diversity and inclusion. Our failure to execute our ESG programs and objectives as planned, or in accordance with the evolving expectations of various stakeholders or regulators in the United States, Europe and globally, could adversely affect the Company’s reputation, business and financial performance. For example, an isolated incident of non-compliance, underperformance or inaccuracy in reporting, the aggregate effect of individually insignificant incidents or the failures of suppliers in our supply chain, can erode trust and confidence in the Company and our brand and adversely affect our business and financial performance, particularly if such events result in adverse publicity, governmental investigations or litigation. Simultaneously, increased expectations and regulations around ESG reporting and performance may result in higher operating expenses, capital expenditures and costs of goods sold (including those related to deploying low-carbon technologies, expanding our electric vehicle fleet, strengthening ESG monitoring and reporting programs, calculating and disclosing different scopes of greenhouse gas emissions in the manner and timeline expected by regulators and other stakeholders, enhancing supply chain transparency programs, transitioning suppliers due to their ESG programs, other costs to pursue our ESG goals or supplier price increases as manufacturers and services providers accommodate their own ESG-related expenses), which could reduce our profitability and cash flow. Additionally, certain customers may set net-zero emissions targets, and we could face pressure from such customers to further reduce emissions to assist them in the achievement of such targets or risk the loss of their business, which could result in increased costs or decreased revenue and may adversely impact financial performance. Risks Related to Tax Matters Changes in tax laws or challenges to the Company's tax positions by taxing authorities could adversely impact the Company's results of operations and financial condition. We are subject to taxes in jurisdictions in which we do business, including but not limited to taxes imposed on our income, receipts, stockholders' equity, property, sales, purchases and payroll. As a result, the tax expense we incur can be adversely affected by changes in tax law. We cannot anticipate these changes in tax law, which can cause unexpected volatility in our results of operations. Changes in the tax law at the federal and state/provincial levels, in particular in the U.S. and Canada, jurisdictions which account for most of our income before taxes, can have a material adverse effect on our results of operations. The Organization for Economic Cooperation and Development (the “OECD”) issued proposed rules to address the tax challenges arising from the digitalization of the global economy. The so-called two-pillar solution is intended to implement rules 21 addressing 1) nexus and profit allocation in cases where businesses profit from markets in other countries while paying little to no tax in those countries under the current physical presence-based global tax system, 2) standardized intercompany pricing for routine marketing and distribution activities, and 3) a global minimum tax as a catch-all to address residual base erosion and profit shifting. Each of the OECD’s member states must enact domestic legislation implementing the OECD’s proposed rules for them to become law, which a number of jurisdictions either did during 2023 or are expected to do in 2024. The Company is evaluating the impact of the guidance released by the OECD and proposed and enacted domestic legislation in relevant member states, as well as information released by the Financial Accounting Standards Board, to determine the effect on the Company. While a comprehensive analysis of the proposed and enacted domestic legislation and OECD proposals is still being conducted, the Company’s preliminary conclusions are that the current proposed and enacted rules are not likely to have a material impact on the Company’s worldwide tax expense but are likely to create significant compliance obligations. Finally, the tax laws to which the Company is subject are inherently complex and ambiguous. Therefore, we must interpret the applicable laws and make subjective judgments about the expected outcome upon challenge by the applicable taxing authorities. As a result, the impact on our results from operations of the application of enacted tax laws to our facts and circumstances is sometimes uncertain. If atax a uthority successfully challenges our interpretation and application of the tax law to our facts and circumstances, there can be no assurance that we can accurately predict the outcome and the taxes ultimately owed upon effective settlement, which may differ from the tax expense recognized in our Consolidated Statements of Income and Comprehensive Income and accrued in our Consolidated Balance Sheets. Additionally, if we cannot meet liquidity requirements in the U.S., we may have to repatriate funds from overseas to meet these liabilities, which would result in additional income taxes being incurred on the amount repatriated. Risks Related to Our Indebtedness and Capital Structure Our outstanding indebtedness requires debt service commitments that could adversely affect our ability to fulfill our obligations and could limit our growth and impose restrictions on our business, and fluctuations in interest rates could affect the cost of our indebtedness. In 2020, we incurred significant additional indebtedness to finance the merger with Anixter. As a result, a substantial portion of our cash flow from operations must be dedicated to the payment of principal and interest on our indebtedness, thereby reducing the funds available to us for other purposes. As of December 31, 2023, excluding debt discount and debt issuance costs, we had $5.4 billion of consolidated indebtedness. We and our subsidiaries may also undertake additional borrowings in the future, subject to certain limitations contained in the debt instruments governing our indebtedness. Our debt service obligations impact our ability to operate and grow our business. Our payments of principal and interest on our indebtedness reduce the amount of funds available to us to invest in operations, future business opportunities, acquisitions, and other potentially beneficial activities. Our debt service obligations also reduce our flexibility to adjust to changing market conditions and may increase our vulnerability to adverse economic, political, financial market and industry conditions. A portion of our indebtedness, including amounts outstanding under our accounts receivable securitization and revolving credit facilities, bears interest at variable rates. In the future, we may also incur additional indebtedness that bears interest at variable rates. In a rising interest rate environment, or one in which interest rates may be affected by market disruptions, the interest expense on our variable rate borrowings will increase. Our ability to service and refinance our indebtedness, make scheduled payments on our operating leases, fund capital expenditures, acquisitions or other business opportunities, repurchase shares, and pay dividends will depend in large part on both our future performance and the availability of additional financing in the future, as well as prevailing interest rates and other market conditions and other factors beyond our control. We cannot assure you that we will be able to obtain additional financing on terms acceptable to us or at all. There can be no assurance that our business will continue to generate sufficient cash flows from operations in the future to service our debt, make necessary capital expenditures, or meet other cash needs. If the financial performance of the Company does not meet current expectations, then our ability to service or repay our indebtedness may be adversely impacted. If unable to do so, we may be required to refinance all or a portion of our existing debt, sell assets, or obtain additional financing. If we are unable to repay indebtedness, lenders having secured obligations could proceed against the collateral securing these obligations. 22 Our debt agreements contain restrictive covenants that may limit our ability to operate our business. Our credit facilities and our other debt agreements contain various covenants that restrict or limit our ability to, among other things: incur additional indebtedness or create liens on assets; engage in mergers, acquisitions or consolidations; • • • make loans or other investments; • • transfer, lease or dispose of assets outside the ordinary course of business; pay dividends, repurchase equity interests, make other payments with respect to equity interests, repay or repurchase subordinated debt; and • engage in affiliate transactions. In addition, certain of these debt agreements contain financial covenants that may require us to maintain certain financial ratios and other requirements in certain circumstances. As a result of these covenants, our ability to respond to changes in business and economic conditions and to obtain additional financing, if needed, may be significantly restricted, and we may be prevented from engaging in transactions or taking advantage of new business opportunities that might otherwise be beneficial to us. Our ability to comply with these covenants and restrictions may be affected by economic, financial and industry conditions or regulatory changes beyond our control. Failure to comply with these covenants or restrictions could result in an event of default, under our revolving lines of credit or the indentures governing certain of our outstanding notes which, if not cured or waived, could accelerate our repayment obligations. See the Liquidity and Capital Resources section in Item 7, “Management's Discussion and Analysis” for further details. General Risk Factors We are subject to costs and risks associated with global laws and regulations affecting our business, as well as litigation for product liability or other matters affecting our business. The global legal and regulatory environment is complex and exposes us to compliance costs and risks, as well as litigation and other legal proceedings, which could materially affect our operations and financial results. These laws and regulations may change, sometimes significantly, as a result of political or economic events, and some changes are anticipated to occur in the future. They include laws and regulations covering taxation, trade, import and export, labor and employment (including wage and hour), product safety, product labeling, occupational safety and health, data privacy, data protection, intellectual property, artificial intelligence, and sustainability and environmental matters (including those relating to global climate change and its impact). We are also subject to securities and exchange laws and regulations and other laws applicable to publicly-traded companies such as the Foreign Corrupt Practices Act. Furthermore, as a government contractor selling to federal, state and local government entities, we are also subject to a wide variety of additional laws and regulations. Proposed laws and regulations in these and other areas could affect the cost of our business operations. From time to time we are involved in legal proceedings, audits or investigations which may relate to, for example, product liability, labor and employment (including wage and hour), tax, escheat, import and export compliance, government contracts, worker health and safety, intellectual property misappropriation or infringement, and general commercial and securities matters. While we believe the outcome of any pending matter is unlikely to have a material adverse effect on our financial condition or liquidity, additional legal proceedings may arise in the future and the outcome of these as well as other contingencies could require us to take actions, which could adversely affect our operations, could diminish our intellectual property portfolio or could require us to pay substantial amounts of money. Even if we successfully defend against claims, we may incur significant costs that could adversely affect our results of operations, financial condition and cash flow. 23 We must attract, retain and motivate our employees, and the failure to do so may adversely affect our business. Our success depends on hiring, retaining and motivating our employees, including executive, managerial, sales, technical, operations, marketing and support personnel. We may have difficulty locating and hiring qualified personnel. In addition, we may have difficulty retaining such personnel once hired, and key people may leave and compete against us. The loss of key personnel or our failure to attract and retain other qualified and experienced personnel could disrupt or adversely affect our business, its sales and operating results. In addition, our operating results could be adversely affected by increased costs due to increased competition for employees, higher employee turnover, increasing levels of retirement, the possibility of a shrinking workforce in various regions globally, which may also result in increased employee benefit or other costs or the loss of significant customer business, proprietary information, or tacit knowledge, which could negatively impact our operational efficiency, innovation capabilities, and customer relationships. Furthermore, inadequate talent management and succession planning, along with potential challenges in adapting to evolving workplace trends and expectations, could hinder our ability to respond to market changes and maintain a competitive edge, which could lead to decreased productivity, reduced market share, and ultimately, a decline in financial performance. Item 1B. Unresolved Staff Comments. None. Item 1C. Cybersecurity. Risk Management and Strategy Information security and protection of our data is important to Wesco, our customers and suppliers. We take aco mprehensive, multi-layered approach to securing our data and business systems from attack, compromise or loss. This includes the combination of leading technologies, physical and organizational safeguards, including a robust suite of security policies and procedures. We have a dedicated 24 hours per day/seven days per week Cybersecurity Operations team, with a third-party service provider, monitoring our environment for signs of attack and responding in real-time. The implementation of a multi-layer and multi-provider portfolio of technologies is designed to deliver overlapping coverage against today’s cybersecurity threats with a strong defensive and response driven security posture. We evaluate risks, threats, intelligence feeds and vulnerabilities to adapt, mitigate or respond as appropriate to preserve a secure state. Additionally, Wesco has aco mprehensive third-party risk management program to evaluate partners prior to onboarding, throughout the life of the relationship, and through the close out of the relationship. This program is designed to ensure our third-party partners adhere to Wesco’s security policies and expectations as the threat landscape evolves and the relation between the organization changes. Wesco’s cybersecurity programs are reviewed as part of our information security management system (“ISMS”) by external, independent third parties and in 2022, we achieved ISO 27001 certification for our ISMS. We conduct mandatory information security awareness training for our employees at least annually and enhanced training for specialized personnel. We have instituted regular attack or malicious activity simulations for employees to enhance awareness and responsiveness to such possible threats, and we also employ third parties to perform penetration and vulnerability tests. While we focus on prevention and detection, we have response and recovery plans in place, as well as service agreements and partner engagements should there be a need for us to respond to an attack. We have adopted a cybersecurity incident response plan that provides direction and a defined approach for preparing for, identifying and responding to cybersecurity incidents that may pose apo tential threat to our information systems, networks and data. The plan defines the roles and responsibilities of our IT and security teams and other functional teams that comprise the cybersecurity incident response team, as well as provides controls and procedures for timely and accurate reporting of material cybersecurity incidents. Significant cybersecurity incidents are reviewed by acr oss-functional team to determine whether further escalation is appropriate. Any incident that potentially is, or may become, material is reported to senior management for materiality and disclosure determinations. We also maintain cyber liability insurance coverage. While we did not experience any material data breaches in 2023 and no risks from cybersecurity threats have materially impacted or are reasonably likely to materially impact the Company’s business strategy, operations, or financial condition, we cannot provide assurance that they will not be materially affected in the future by such risks or any future material incidents. For more information on our cybersecurity related risks, see Item 1A, “Risk Factors” of this Annual Report on Form 10-K. 24 Governance To more effectively prevent, detect and respond to information security threats, we have a dedicated Chief Information Security Officer (“CISO”) whose team is responsible for leading enterprise-wide information security strategy, policy, standards, architecture and processes. The CISO, with over 30 years of technology experience, has been in this role with Wesco since 2020, has ato tal of eight years of experience serving in the role of Chief Information Security Officer, and has twelve years of experience dedicated to cybersecurity. The CISO reports to our Executive Vice President, Chief Information and Digital Officer (“CIDO”), who reports directly to our Chief Executive Officer. The CISO and CIDO regularly review cybersecurity matters with our Chief Executive Officer and other members of our senior management, including cybersecurity risks and threats and the status of our cybersecurity incident response plan and related processes relating to the prevention, detection, mitigation and remediation of cybersecurity incidents. As part of its oversight responsibility of cybersecurity risk and the overall enterprise risk management process, the Audit Committee of our Board of Directors meets at least quarterly with our CISO, CIDO, and other senior leaders to receive updates on cybersecurity risks and threats (and should they arise, any material incidents), the status of initiatives to strengthen our information security systems, management's assessments of our security program, and compliance with disclosure requirements. The Audit Committee and senior management report any findings and recommendations, as appropriate to the full Board of Directors for consideration. Wesco’s cybersecurity program is regularly evaluated by internal and external experts with the results of those reviews reported to senior leadership and the Board of Directors. We also actively engage with strategic partners, industry groups, and intelligence and law enforcement to better understand macro trends and significant risk concerns to better inform and enhance our cybersecurity policies and procedures. Item 2. Properties. We operate a network of approximately 625 branches and warehouse locations that hold inventory, and approximately 140 sales offices, with operations in approximately 50 countries throughout the world. This includes 54 facilities with square footage between 100,000 and 500,000 that operate as regional distribution centers or large branch locations, of which 42 are located in the U.S., eight in Canada, two in Europe and two in South America. Approximately 8% of our facilities are owned, and the remainder are leased. We also lease our 118,000 square-foot headquarters in Pittsburgh, Pennsylvania. We do not regard the real property associated with any single facility as material to our operations. We believe our facilities are in good operating condition and are adequate for their respective uses. Item 3. Legal Proceedings. From time to time, a number of lawsuits and claims have been or may be asserted against us relating to the conduct of our business, including litigation relating to commercial, product and employment matters (including wage and hour). The outcome of any litigation cannot be predicted with certainty, and some lawsuits may be determined adversely to us. However, management does not believe that the ultimate outcome of any such pending matters is likely to have amaterial adverse effect on our financial condition or liquidity, although the resolution in any fiscal period of one or more of these matters may have a material adverse effect on our results of operations for that period. Information relating to legal proceedings is disclosed in Note 15, “Commitments and Contingencies” of the Notes to Consolidated Financial Statements and is incorporated herein by reference. Item 4. Mine Safety Disclosures. Not applicable. 25 PART II Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities. Market, Stockholder, and Dividend Information. Our common stock is listed on the New York Stock Exchange under the symbol “WCC”. As of February 16, 2024, there were 50,953,600 shares of common stock outstanding held by approximately 860 holders of record. We began paying a quarterly cash dividend on our common stock starting in the first quarter of 2023. During each of the quarters in the fiscal year ended December 31, 2023, we paid a quarterly cash dividend of $0.375 per common share to our shareholders. The payment of dividends is within the discretion of our Board of Directors and any decision to pay dividends in the future, and the amount of any such dividend, will depend on an evaluation of a number of factors, including our financial condition, earnings, capital requirements, debt service obligations, restrictive covenants contained in our debt agreements, and other factors deemed relevant by our Board of Directors. As disclosed in Note 9, “Debt” of our Notes to Consolidated Financial Statements, the terms of the Revolving Credit Facility, as well as the indentures governing the 7.125% Senior Notes due 2025 and 7.250% Senior Notes due 2028 contain various restrictive covenants that limit the amount of dividends and common stock repurchases that can be made. We were in compliance with these conditions in 2023 and expect to be in 2024. Issuer Purchases of Equity Securities. The following table sets forth all issuer purchases of common stock during the three months ended December 31, 2023: Period October 1, 2023 - October 31, 2023 November 1, 2023 - November 30, 2023 December 1, 2023 - December 31, 2023 Total Total Number of Shares Purchased(1) Average Price Paid Per Share Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs(2) Approximate Dollar Value of Shares That May Yet be Purchased Under the Plans or Programs(2) (In millions) 57 $ 178,886 $ 1,325 $ 180,268 $ 143.52 139.75 174.90 140.01 — $ 178,886 $ — $ 178,886 938.9 913.9 913.9 (1) There were 1,382 shares purchased during the quarterly period ended December 31, 2023 that were not part of the publicly announced share repurchase program. These shares were surrendered by stock-based compensation plan participants to satisfy tax withholding obligations arising from the exercise of stock-settled stock appreciation rights, and vesting of restricted stock units and performance-based awards. (2) On June 1, 2022, Wesco announced that its Board of Directors authorized, on May 31, 2022, the repurchase of up to $1 billion of the Company's common stock and Series A Preferred Stock. The share repurchase authorization has no expiration date and may be modified, suspended, or terminated at any time without prior notice. During the three months ended December 31, 2023, the Company entered into spot repurchase transactions through a broker to purchase 178,886 shares of its common stock in the open market for cash totaling $25.0 million. Wesco funded the repurchases with available cash and borrowings under its revolving credit facility. 26 Company Performance.

The following discussion should be read in conjunction with the audited consolidated financial statements and notes thereto included in Item 8 of this Annual Report on Form 10-K. The matters discussed herein may contain forward-looking statements that are subject to certain risks and uncertainties that could cause actual results to differ materially from expectations. Certain of these risks are set forth in Item 1A of this Annual Report on Form 10-K. In this Item 7, “Wesco” refers to WESCO International, Inc., and its subsidiaries and its predecessors unless the context otherwise requires. References to “we,” “us,” “our” and the “Company” refer to Wesco and its subsidiaries. In addition to the results provided in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), our discussion and analysis of financial condition and results of operations includes certain non-GAAP financial measures, which are defined further below. These financial measures include organic sales growth, earnings before interest, taxes, depreciation and amortization (“EBITDA”), adjusted EBITDA, adjusted EBITDA margin, financial leverage, adjusted selling, general and administrative expenses, adjusted income from operations, adjusted other non-operating expense (income), adjusted provision for income taxes, adjusted income before income taxes, adjusted net income, adjusted net income attributable to WESCO International, Inc., adjusted net income attributable to common stockholders, and adjusted earnings per diluted share. We believe that these non-GAAP measures are helpful to users of our financial statements as they provide a better understanding of our financial condition and results of operations on a comparable basis. Additionally, certain non-GAAP measures either focus on or exclude items impacting comparability of results, allowing users to more easily compare our financial performance from period to period. Management uses certain non-GAAP financial measures in its evaluation of the performance of the Company's operating segments and in the determination of incentive compensation. Management does not use these non-GAAP financial measures for any purpose other than the reasons stated above. In the first quarter of the fiscal year ended December 31, 2023, we changed our presentation in tables from thousands to millions. Certain amounts as of and for the year ended December 31, 2022 in Management’s Discussion and Analysis of Financial Condition and Results of Operations may not foot or recalculate due to rounding. Company Overview Wesco, headquartered in Pittsburgh, Pennsylvania, is alead ing provider of business-to-business distribution, logistics services and supply chain solutions. We employ approximately 20,000 people, maintain relationships with more than 50,000 suppliers, and serve nearly 150,000 customers worldwide. With millions of products, end-to-end supply chain services, and leading digital capabilities, we provide innovative solutions to meet customer needs across commercial and industrial businesses, contractors, government agencies, educational institutions, telecommunications providers, and utilities. Our innovative value-added solutions include supply chain management, logistics and transportation, procurement, warehousing and inventory management, as well as kitting and labeling, limited assembly of products and installation enhancement. We operate nearly 800 branches, warehouses and sales offices in approximately 50 countries, providing a local presence for customers and a global network to serve multi-location businesses and global corporations. In 2021, we established ane w corporate brand strategy to adopt a single, master brand architecture. This initiative reflects our corporate integration strategy and simplifies engagement for our customers and suppliers. In 2022, we launched the master brand identity in North America and began migrating certain legacy sub-brands to the master brand architecture, a process that will continue for the next several years. In 2023, we launched the Wesco Anixter go-to-market brand in all markets outside of the U.S. and Canada, as part of our master brand deployment strategy. Due to the strength of its recognition with customers and suppliers, we will continue to use the Anixter brand name globally for the foreseeable future. We have operating segments comprising three strategic business units consisting of Electrical & Electronic Solutions (“EES”), Communications & Security Solutions (“CSS”) and Utility & Broadband Solutions (“UBS”). These operating segments are equivalent to our reportable segments. See Item 1, “Business” in this Annual Report on Form 10-K for adesc ription of each of our reportable segments and their business activities. 28 Overall Financial Performance Our financial results for 2023 compared to 2022 reflect single-digit sales growth driven by the benefits of price inflation, increased scale, and secular demand trends. These impacts were partially offset by volume declines in certain businesses, as well as slight margin contraction, and higher payroll and payroll-related expenses, costs to operate our facilities, along with expenses associated with our digital transformation initiatives. Net sales for 2023 increased $965.1 million, or 4.5%, over the prior year. The increase reflects the estimated impact of changes in price of approximately 3% and the favorable impact of 2.1% from the acquisition of Rahi Systems Holdings, Inc. (“Rahi Systems”), which closed in November of 2022. These positive factors were partially offset by the negative impacts of fluctuations in foreign exchange rates of 0.4% and the number of workdays of 0.4%. Volume growth did not have a material impact on the year-over-year increase in organic sales. Cost of goods sold as a percentage of net sales was 78.4% and 78.2% for 2023 and 2022, respectively. The unfavorable increase of 20 basis points reflects lower supplier volume rebates and ash ift in sales mix, partially offset by our continued focus on a strategy of pricing products and services to realize the value that we provide to our customers as a result of our broad portfolio of product and service offerings, global footprint and capabilities (“value-driven pricing”). Income from operations was $1,406.4 million for 2023, compared to $1,438.1 million for 2022, a decrease of $31.7 million, or 2.2%. Income from operations as a percentage of net sales was 6.3% for the current year, compared to 6.7% for the prior year. Income from operations for 2023 includes merger-related and integration costs of $55.4 million, restructuring costs of $16.7 million, and accelerated trademark amortization expense of $1.6 million. Adjusted for these items, income from operations was 6.6% of net sales in 2023. For 2022, income from operations was 7.1% of net sales, as adjusted for merger-related and integration costs of $67.4 million and accelerated trademark amortization expense of $9.8 million. For 2023, income from operations declined compared to the prior year due to higher cost of goods sold as a percentage of net sales, higher salaries and benefits due to wage inflation and increased headcount, including the impact of the Rahi Systems acquisition, as well as an increase in volume-related costs such as commissions and marketing costs. The costs to operate our facilities also unfavorably affected income from operations. In addition, digital transformation initiatives contributed to higher expenses in 2023. These negative factors were partially offset by sales growth as well as the realization of integration synergies and aredu ction to incentive compensation expense. Earnings per diluted share for 2023 was $13.54, based on 52.3 million diluted shares, compared to $15.33 for 2022, based on 52.4 million diluted shares, a decrease of 11.7%. Adjusted for merger-related and integration costs, restructuring costs, accelerated trademark amortization expense, net pension settlement cost, and the related income tax effects, earnings per diluted share for 2023 was $14.60. Adjusted for merger-related and integration costs, accelerated trademark amortization expense, and the related income tax effects, earnings per diluted share for 2022 was $16.42. Adjusted earnings per diluted share decreased 11.1% year- over-year. Our industry and the broader economy have experienced supply chain challenges, including product delays and backlogged orders, shortages in raw materials and components, labor shortages, transportation challenges, and higher costs. We have aggressively responded to these supply chain issues which have largely improved and progressively become manageable throughout 2023. Cash Flow Operating cash flow for 2023 was $493.2 million. Net cash provided by operating activities included net income of $766.1 million and non-cash adjustments to net income totaling $235.8 million, which primarily consisted of depreciation and amortization of $181.3 million, stock-based compensation expense of $48.1 million, amortization of debt discount and debt issuance costs of $14.8 million, and deferred income taxes of $7.9 million. Operating cash flow was negatively impacted by net changes in assets and liabilities of $508.7 million, which primarily consisted of a decrease in accounts payable of $319.7 million, mainly due to a reduction in inventory purchases in the fourth quarter, and an increase in inventories of $68.4 million. Inventories grew at a slower rate than sales, as supply chain lead times have normalized. These cash usage factors were partially offset by cash inflow from a decrease in trade accounts receivable of $52.2 million. Additionally, the payment of management incentive compensation earned in 2022 resulted in a cash outflow of approximately $153.9 million in 2023, which was partially offset by the accrual of management incentive compensation earned in the current year. 29 Investing activities primarily included $92.3 million of capital expenditures mostly consisting of internal-use computer software and information technology hardware to support our digital transformation initiatives, as well as equipment and leasehold improvements to support our global network of branches, warehouses and sales offices. Financing activities primarily consisted of net repayments of $70.3 million related to our revolving credit facility (the “Revolving Credit Facility”) and the repayment of our $58.6 million aggregate principal amount of 5.50% Anixter Senior Notes due 2023, which matured on March 1, 2023, partially offset by net borrowings of $15.0 million related to our accounts receivable securitization facility (the “Receivables Facility”). Financing activities for 2023 also included $76.6 million and $57.4 million of dividends paid to holders of our common stock and Series A Preferred Stock, respectively, $75.0 million of common stock repurchases, and $68.3 million of payments for taxes related to the exercise and vesting of stock-based awards. Financing Availability As of December 31, 2023, we had $736.0 million in total available borrowing capacity under our Revolving Credit Facility and $75.0 million of available borrowing capacity under our Receivables Facility. The Revolving Credit Facility and the Receivables Facility mature in March 2027 and March 2025, respectively. As of December 31, 2023, we also had $8.2 million of borrowing capacity available under our international lines of credit that did not directly reduce availability under the Revolving Credit Facility. Critical Accounting Estimates Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates that involve a significant level of estimation uncertainty and have had or are reasonably likely to have a material impact on the financial condition or results of operations, including those related to goodwill and indefinite-lived intangible assets, defined benefit pension plans, and income taxes. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. If actual market conditions are less favorable than those projected by management, additional adjustments to reserve items may be required. We believe the following accounting estimates are the most critical to the understanding of our consolidated financial statements as they require subjective or complex judgments by management. Goodwill and Indefinite-Lived Intangible Assets Goodwill and indefinite-lived intangible assets are tested for impairment annually as of October 1, or more frequently if triggering events occur, indicating that their carrying values may not be recoverable. We test for goodwill impairment on a reporting unit level. We performed our annual impairment tests of goodwill and indefinite-lived intangible assets during the fourth quarter of 2023 by assessing qualitative factors to determine whether it was more likely than not that the fair values of our reporting units and indefinite-lived intangible assets were less than their respective carrying amounts. As a result of this assessment, we determined that it was more likely than not that the fair values of our reporting units and indefinite-lived intangible assets continued to exceed their respective carrying amounts and, therefore, aqua ntitative impairment test was not necessary. The determination of fair value involves significant management judgment, particularly as it relates to the underlying assumptions and factors around future expected operating margins and discount rate. Management applies its best judgment when assessing the reasonableness of financial projections. Fair values are sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of the annual goodwill and indefinite- lived intangible impairment tests will prove to be an accurate prediction of future results. See Note 2, “Accounting Policies” and Note 5, “Goodwill and Intangible Assets” of our Notes to Consolidated Financial Statements for additional disclosure regarding goodwill and indefinite-lived intangible assets. 30 Defined Benefit Pension Plans Liabilities and expenses for defined benefit pension plans are determined using actuarial methodologies and incorporate significant assumptions, including the interest rate used to discount the future estimated cash flows, the expected long-term rate of return on plan assets, and several assumptions relating to the employee workforce (salary increases, retirement age, and mortality). Liabilities for defined benefit pension plans are particularly sensitive to changes in the discount rate. At the end of each fiscal year, we determine the discount rate to measure our defined benefit pension plan liabilities at their present value. The discount rate reflects the current rate at which the defined benefit pension plan liabilities could be effectively settled at the end of the year. This rate is estimated using a yield curve based on corporate bond data, which we believe is consistent with observable market conditions and industry standards for developing spot rate curves. The consolidated weighted-average discount rate used to measure the projected benefit obligation of all plans was 4.4% and 4.6% at December 31, 2023 and 2022, respectively. As a sensitivity measure, the effect of a 50-basis-point decline in the assumed discount rate would result in no change in the expense for 2024, and an increase in our projected benefit obligations at December 31, 2023 of $31.0 million. The impact of a 50-basis- point increase in the assumed discount rate would result in a decrease in the expense for 2024 of approximately $1.0 million, and a decrease in our projected benefit obligations at December 31, 2023 of $29.0 million. Changes in the expected long-term rate of return on plan assets and assumptions relating to the employee workforce are less likely to have a material impact on the measurement of defined benefit pension plan liabilities. See Note 2, “Accounting Policies” and Note 13, “Employee Benefit Plans” of our Notes to Consolidated Financial Statements for additional disclosure regarding defined benefit pension plans. Income Taxes We recognize deferred tax assets consistent with amounts expected to be realized. To make such determination, management evaluates all positive and negative evidence, including but not limited to, prior, current and future taxable income, tax planning strategies and future reversals of existing taxable temporary differences. A valuation allowance is recognized if it is “more-likely- than-not” that some or all of a deferred tax asset will not be realized. We regularly assess the realizability of deferred tax assets. We account for uncertainty in income taxes using a “more-likely-than-not” recognition threshold. Due to the subjectivity inherent in the evaluation of uncertain tax positions, the tax benefit ultimately recognized may materially differ from the estimate recognized in the consolidated financial statements. We recognize interest and penalties related to uncertain tax benefits as part of interest expense and income tax expense, respectively. See Note 2, “Accounting Policies” and Note 11, “Income Taxes” of our Notes to Consolidated Financial Statements for additional disclosure regarding income taxes. Results of Operations 2023 Compared to 2022 Net Sales The following table sets forth net sales and organic sales growth for the periods presented: Year Ended December 31, Growth/(Decline) 2023 2022 Reported Acquisition (In millions) Foreign Exchange Workday Organic Sales Net sales $ 22,385.2 $ 21,420.1 4.5 % 2.1 % (0.4)% (0.4)% 3.2 % 31 Note: Organic sales growth is a non-GAAP financial measure of sales performance. Organic sales growth is calculated by deducting the percentage impact from acquisitions and divestitures for one year following the respective transaction, fluctuations in foreign exchange rates and number of workdays from the reported percentage change in consolidated net sales. Workday impact represents the change in the number of operating days period-over-period after adjusting for weekends and public holidays in the United States; 2023 had one less workday compared to 2022. Net sales were $22.4 billion for 2023 compared with $21.4 billion for 2022, an increase of 4.5%. Adjusting for the favorable impact from the acquisition of Rahi Systems of 2.1%, the unfavorable impacts from fluctuations in foreign exchange rates of 0.4% and the number of workdays of 0.4%, organic sales for 2023 grew by 3.2%. The increase was primarily due to the impact of changes in price, which favorably impacted organic sales by approximately 3%. Volume growth did not have a material impact on the year-over-year increase in organic sales, as increases in sales volume in the CSS and UBS operating segments were offset by a decrease in sales volume in the EES segment. Cost of Goods Sold Cost of goods sold for 2023 was $17.5 billion compared to $16.8 billion for 2022. Cost of goods sold as a percentage of net sales was 78.4% and 78.2% for 2023 and 2022, respectively. The unfavorable increase of 20 basis points reflects a shift in sales mix and lower supplier volume rebates, partially offset by our continued focus on a strategy of pricing products and services to realize the value that we provide to our customers as aresu lt of our broad portfolio of product and service offerings, global footprint and capabilities (“value-driven pricing”). Selling, General and Administrative Expenses Selling, general and administrative (“SG&A”) expenses primarily include payroll and payroll-related costs, shipping and handling, travel and entertainment, facilities, utilities, information technology expenses, professional and consulting fees, credit losses, gains (losses) on the sale of property and equipment, as well as real estate and personal property taxes. SG&A expenses for 2023 totaled $3.3 billion versus $3.0 billion for 2022, an increase of 7.0%. As a percentage of net sales, SG&A expenses were 14.5% and 14.2% for 2023 and 2022, respectively. SG&A expenses for 2023 and 2022 include merger-related and integration costs of $55.4 million and $67.4 million, respectively. SG&A expenses for 2023 also include $16.7 million of restructuring costs. Adjusted for merger-related and integration costs, and restructuring costs, SG&A expenses for 2023 were 14.2% of net sales for 2023 and 13.9% of net sales for 2022. SG&A payroll and payroll-related expenses for 2023 of $2.1 billion increased by $89.4 million compared to 2022 as a result of higher salaries and benefits due to wage inflation and increased headcount, including the impact of the Rahi Systems acquisition, partially offset by the impact of headcount reductions taken at the end of the second quarter of 2023. This increase in payroll and payroll-related expenses also includes an increase in sales commissions of $31.9 million and a reduction to incentive compensation expense of $98.3 million. SG&A expenses not related to payroll and payroll-related costs for 2023 were $1.2 billion, an increase of $122.4 million compared to 2022, which primarily reflects higher costs to operate our facilities of $49.2 million, increased marketing costs of $11.5 million, as well as higher employee expenses of $6.6 million due to increased headcount. In addition, digital transformation initiatives contributed to higher expenses of $22.4 million in 2023, which includes higher professional and consulting expenses. These increases were partially offset by the realization of integration cost synergies. Depreciation and Amortization Depreciation and amortization increased $2.3 million to $181.3 million for 2023, compared to $179.0 million for 2022. Depreciation and amortization for 2023 and 2022 includes $1.6 million and $9.8 million, respectively, of accelerated amortization expense resulting from changes in the estimated useful lives of certain legacy trademarks that are migrating to our master brand architecture. Income from Operations Income from operations was $1,406.4 million for 2023 compared to $1,438.1 million for 2022. The decrease of $31.7 million, or 2.2%, reflects slightly higher cost of goods sold as a percentage of net sales and higher SG&A expenses, as described above, partially offset by sales growth and the realization of integration synergies. 32 Interest Expense, net Net interest expense totaled $389.3 million for 2023 compared to $294.4 million for 2022. The increase of $94.9 million, or 32.2%, reflects higher borrowings and an increase in variable interest rates. Other Expense, net Other non-operating expense totaled $25.1 million for 2023 compared to $7.0 million for 2022. Due to fluctuations in the U.S. dollar against certain foreign currencies, particularly the Argentine Peso and the Egyptian Pound, a net foreign currency exchange loss of $22.9 million was recognized for 2023 compared to a net loss of $19.9 million for 2022. We recognized net costs of $0.2 million and net benefits of $14.8 million associated with the non-service cost components of net periodic pension cost (benefit) for 2023 and 2022, respectively. The year-over-year change was primarily due to ade crease in expected return on plan assets and an increase in interest cost. Other non-operating expense for 2023 includes net pension settlement cost of $2.8 million primarily related to the partial settlement of the Company's pension plan in the U.S., partially offset by pension settlement gains related to other plans. Adjusted for this amount, other non-operating expense was $22.3 million for 2023. Income Taxes The provision for income taxes was $225.9 million for 2023 compared to $274.5 million for 2022, resulting in effective tax rates of 22.8% and 24.2%, respectively. The effective tax rate for both the current year and the prior year were favorably impacted by the tax benefits related to the exercise and vesting of stock-based awards and reductions in the valuation allowance recorded against certain deferred tax assets. The lower effective tax rate in the current year is due primarily to higher tax benefits from stock-based compensation deductions and foreign tax credit utilization as compared to the prior year. Net Income and Earnings per Share Net income and earnings per diluted share attributable to common stockholders were $708.1 million and $13.54, respectively, for 2023 compared to $803.1 million and $15.33, respectively, for 2022. Adjusted for merger-related and integration costs, restructuring costs, accelerated trademark amortization expense, net pension settlement cost, and the related income tax effects, net income and earnings per diluted share attributable to common stockholders were $763.6 million and $14.60, respectively, for the year ended December 31, 2023. Adjusted for merger-related and integration costs, accelerated trademark amortization expense, and the related income tax effects, net income and earnings per diluted share attributable to common stockholders were $860.1 million and $16.42, respectively, for the year ended December 31, 2022. Adjusted EBITDA Adjusted EBITDA, a non-GAAP financial measure, was $1,705.3 million for 2023 compared to $1,725.6 million for 2022. Adjusted EBITDA decreased $20.3 million, or 1.2% year-over-year. The decrease primarily reflects the $211.8 million increase in SG&A expenses, as well as the increase in cost of goods sold of $782.7 million, partially offset by the $1.0 billion increase in net sales, as described above. Included in the increase in SG&A expenses was restructuring costs of $16.7 million, partially offset by a decrease in merger-related and integration costs of $12.0 million. Segment Results The following is a discussion of the financial results of our operating segments comprising three strategic business units consisting of EES, CSS and UBS for the year ended December 31, 2023. As further described below and in Note 16, “Business Segments” of our Notes to the Consolidated Financial Statements, the performance of our operating segments is based on net sales, adjusted EBITDA, and adjusted EBITDA margin percentage. Adjusted EBITDA and adjusted EBITDA margin percentage are non-GAAP financial measures. 33 Electrical & Electronic Solutions Year Ended December 31, 2023 2022 (In millions) Reported Acquisition Growth/(Decline) Foreign Exchange Workday Organic Sales Net sales Adjusted EBITDA Adjusted EBITDA margin % $ $ $ $ 8,610.3 727.4 8.4 % 8,823.3 851.3 9.6 % (2.4)% — % (0.6)% (0.4)% (1.4)% EES reported net sales of $8.6 billion for 2023 compared to $8.8 billion for 2022, a decrease of 2.4%. Adjusting for the unfavorable impact from fluctuations in foreign exchange rates of 0.6% and the number of workdays of 0.4%, EES organic sales for 2023 declined 1.4%, reflecting volume declines of approximately 2%, primarily as aresu lt of declines in construction and original equipment manufacturers, partially offset by continued positive momentum in industrial and the benefits of selling the broader company portfolio (“cross selling”). In addition, a transfer of certain customer accounts to the CSS segment negatively impacted organic net sales for EES by approximately 2%. These negative factors were partially offset by the impact of changes in price, which favorably impacted organic sales by approximately 3%. EES reported adjusted EBITDA of $727.4 million for 2023, or 8.4% of net sales, compared to $851.3 million for 2022, or 9.6% of net sales. Adjusted EBITDA decreased $123.9 million, or 14.6% year-over-year. The decrease primarily reflects the decline in net sales, as described above, and an increase in SG&A expenses as a percentage of net sales, partially offset by a decrease in cost of goods sold of $131.8 million, which is inclusive of higher inventory write-downs and lower supplier volume rebates totaling approximately $28.7 million and the negative impact of a shift in sales mix. SG&A expenses increased $41.6 million as compared to the prior year, which was primarily attributed to higher payroll and payroll-related expenses of $43.6 million as a result of higher salaries due to wage inflation and increased headcount. This increase in payroll and payroll-related expenses also includes a reduction to incentive compensation expense of $31.4 million. Communications & Security Solutions Year Ended December 31, 2023 2022 (In millions) Reported Acquisition Growth/(Decline) Foreign Exchange Workday Organic Sales Net sales Adjusted EBITDA Adjusted EBITDA margin % $ $ $ $ 7,152.2 683.8 9.6 % 6,401.5 599.0 9.4 % 11.7 % 7.1 % (0.4)% (0.4)% 5.4 % CSS reported net sales of $7.2 billion for 2023 compared to $6.4 billion for 2022, an increase of 11.7%. Adjusting for the favorable impact from the acquisition of Rahi Systems of 7.1%, the unfavorable impacts from fluctuations in foreign exchange rates of 0.4% and the number of workdays of 0.4%, CSS organic sales for 2023 grew 5.4%, reflecting the impact of changes in price, which favorably impacted organic sales by approximately 1%. Volume growth, which includes growth in data center, security solutions and enterprise network infrastructure and the benefits of cross selling, favorably impacted organic sales by approximately 1%. The transfer of certain customer accounts from the EES segment also positively impacted organic net sales for CSS by approximately 3%. CSS reported adjusted EBITDA of $683.8 million for 2023, or 9.6% of net sales, compared to $599.0 million for 2022, or 9.4% of net sales. Adjusted EBITDA increased $84.8 million, or 14.2% year-over-year. The increase primarily reflects the increase in net sales, as described above, partially offset by a corresponding increase in cost of goods sold of $580.2 million. SG&A expenses increased $90.5 million as compared to the prior year, which was primarily attributed to higher payroll and payroll- related expenses of $45.1 million as a result of higher salaries due to wage inflation and increased headcount, including the impact of the Rahi Systems acquisition. This increase in payroll and payroll-related expenses also includes an increase in sales commissions of $26.1 million and a reduction to incentive compensation expense of $29.9 million. Additionally, higher costs to operate our facilities of $15.9 million, higher marketing costs of $6.8 million due to increased sales volume, and higher employee expenses of $5.9 million due to increased headcount contributed to the year-over-year increase in SG&A expenses. 34 Utility & Broadband Solutions Year Ended December 31, 2023 2022 (In millions) Reported Acquisition Growth/(Decline) Foreign Exchange Workday Organic Sales Net sales Adjusted EBITDA Adjusted EBITDA margin % $ $ $ $ 6,622.7 739.3 11.2 % 6,195.3 677.3 10.9 % 6.9 % — % (0.2)% (0.4)% 7.5 % UBS reported net sales of $6.6 billion for 2023 compared to $6.2 billion for 2022, an increase of 6.9%. Adjusting for the unfavorable impacts of fluctuations in foreign exchange rates of 0.2% and the number of workdays of 0.4%, UBS organic sales for 2023 grew 7.5%, reflecting the impact of changes in price, which favorably impacted organic sales by approximately 6%. Volume growth, which includes growth in utility and integrated supply, and the benefits of cross selling, partially offset by lower sales in broadband, particularly in Canada, favorably impacted organic sales by approximately 2%. UBS reported adjusted EBITDA of $739.3 million for 2023, or 11.2% of net sales, compared to $677.3 million for 2022, or 10.9% of net sales. Adjusted EBITDA increased $62.0 million, or 9.2% year-over-year. The increase primarily reflects the $427.4 million increase in net sales, as described above, partially offset by a corresponding increase in cost of goods sold of $334.4 million. SG&A expenses increased $31.2 million as compared to the prior year, which was primarily attributed to higher payroll and payroll-related expenses of $13.2 million as a result of higher salaries due to wage inflation and increased headcount. This increase in payroll and payroll-related expenses includes a reduction to incentive compensation expense of $6.5 million and a decrease in sales commissions of $1.1 million. Additionally, higher costs to operate our facilities of $13.9 million and increased transportation costs of $4.1 million as aresu lt of sales growth, contributed to the year-over-year increase in SG&A expenses.

Note: Adjusted EBITDA and Adjusted EBITDA margin % are non-GAAP financial measures that provide indicators of our performance and ability to meet debt service requirements. Adjusted EBITDA is defined as earnings before interest, taxes, depreciation and amortization before other non-operating expenses (income), non-cash stock-based compensation expense, merger-related and integration costs, and restructuring costs. Adjusted EBITDA margin % is calculated by dividing Adjusted EBITDA by net sales. 36 The following tables reconcile selling, general and administrative expenses, income from operations, other non-operating expense, provision for income taxes and earnings per diluted share to adjusted selling, general and administrative expenses, adjusted income from operations, adjusted other non-operating expense, adjusted provision for income taxes and adjusted earnings per diluted share, which are non-GAAP financial measures, for the periods presented: Adjusted SG&A Expenses: Selling, general and administrative expenses Merger-related and integration costs(1) Restructuring costs(2) Adjusted selling, general and administrative expenses Adjusted Income from Operations: Income from operations Merger-related and integration costs(1) Restructuring costs(2) Accelerated trademark amortization(3) Adjusted income from operations Adjusted Other Expense, net: Other expense, net Pension settlement cost(4) Adjusted other expense, net Adjusted Provision for Income Taxes: Provision for income taxes Income tax effect of adjustments to income from operations(5) Adjusted provision for income taxes Year Ended December 31, 2023 2022 (In millions) 3,256.0 (55.4) (16.7) 3,183.9 1,406.4 55.4 16.7 1.6 1,480.1 25.1 (2.8) 22.3 225.9 21.0 246.9 $ $ $ $ $ $ $ $ 3,044.2 (67.4) — 2,976.8 1,438.1 67.4 — 9.8 1,515.3 7.0 — 7.0 274.5 20.2 294.7 $ $ $ $ $ $ $ $ (1) Merger-related and integration costs include integration and professional fees associated with the integration of Wesco and Anixter, including digital transformation costs, as well as advisory, legal, and separation costs associated with the merger between the two companies.

For the year ended December 31, 2022, SG&A expenses, income from operations, the provision for income taxes and earnings per diluted share have been adjusted to exclude merger-related and integration costs, accelerated trademark amortization expense associated with migrating to our master brand architecture, and the related income tax effects. These non-GAAP financial measures provide a better understanding of our financial results on a comparable basis. Liquidity and Capital Resources Our liquidity needs generally arise from fluctuations in our working capital requirements, information technology investments, capital expenditures, acquisitions, the payment of dividends, and debt service obligations. As of December 31, 2023, we had $736.0 million in available borrowing capacity under our Revolving Credit Facility, after giving effect to outstanding letters of credit and certain borrowings under our international lines of credit, and $75.0 million in available borrowing capacity under our Receivables Facility, which combined with available cash of $250.1 million, provided liquidity of $1.1 billion. Cash included in our determination of liquidity represents cash in certain deposit and interest-bearing investment accounts. We monitor the depository institutions that hold our cash and cash equivalents on a regular basis, and we believe that we have placed our deposits with creditworthy financial institutions. We regularly review our mix of fixed versus variable rate debt, and we may, from time to time, issue or retire borrowings and/or refinance existing debt in an effort to mitigate the impact of interest rate and foreign exchange rate fluctuations, and to maintain a cost-effective capital structure consistent with our anticipated capital requirements. Economic conditions contributed to increases in interest rates during 2023 and 2022. Further increases will raise the rates we pay on our variable rate debt and will contribute to higher interest expense versus prior periods. At December 31, 2023, approximately 53% of our debt portfolio consisted of fixed rate debt. We believe our capital structure has an appropriate mix of fixed versus variable rate debt and secured versus unsecured instruments. Over the next several quarters, we expect that our excess liquidity will be directed primarily at debt reduction, digital transformation initiatives, returning capital to shareholders through the payment of dividends and our existing share repurchase authorization, or potential acquisitions and related integration activities. We expect to maintain sufficient liquidity through our credit facilities and cash balances. We believe cash provided by operations and financing activities will be adequate to cover our operational and business needs for at least the next twelve months. 38 We communicate on a regular basis with our lenders regarding our financial and working capital performance, and liquidity position. We were in compliance with all financial covenants and restrictions contained in our debt agreements as of December 31, 2023. We also measure our ability to meet our debt obligations based on our financial leverage ratio, which was 2.8x as of December 31, 2023 and 2.9x as of December 31, 2022. The following table sets forth our financial leverage ratio, which is a non-GAAP financial measure, for the periods presented: (In millions of dollars, except ratios) Net income attributable to common stockholders Net income attributable to noncontrolling interests Preferred stock dividends Provision for income taxes Interest expense, net Depreciation and amortization EBITDA Other expense, net Stock-based compensation expense Merger-related and integration costs(1) Restructuring costs(2) Adjusted EBITDA Short-term debt and current portion of long-term debt, net Long-term debt, net Debt discount and debt issuance costs(3) Fair value adjustments to Anixter Senior Notes due 2023 and 2025(3) Total debt Less: Cash and cash equivalents Total debt, net of cash Twelve months ended December 31, 2023 December 31, 2022 $ $ $ $ $ 708.1 0.6 57.4 225.9 389.3 181.3 1,562.6 25.1 45.5 55.4 16.7 1,705.3 $ $ $ As of 803.1 1.7 57.4 274.5 294.4 179.0 1,610.1 7.0 41.0 67.4 — 1,725.6 December 31, 2023 8.6 5,313.1 43.0 (0.1) 5,364.6 524.1 4,840.5 December 31, 2022 70.5 5,346.0 57.9 (0.3) 5,474.1 527.3 4,946.8 $ $ Financial leverage ratio 2.8 2.9 (1) Merger-related and integration costs include integration and professional fees associated with the integration of Wesco and Anixter, including digital transformation costs, as well as advisory, legal, and separation costs associated with the merger between the two companies. (2) Restructuring costs include severance costs incurred pursuant to an ongoing restructuring plan. (3) Debt is presented in the Consolidated Balance Sheets net of debt discount and debt issuance costs, and includes adjustments to record the long-term debt assumed in the merger with Anixter at its acquisition date fair value. Note: Financial leverage ratio is a non-GAAP measure of the use of debt. Financial leverage ratio is calculated by dividing total debt, excluding debt discount, debt issuance costs and fair value adjustments, net of cash, by adjusted EBITDA. EBITDA is defined as the trailing twelve months earnings before interest, taxes, depreciation and amortization. Adjusted EBITDA is defined as the trailing twelve months EBITDA before other non-operating expense (income), non-cash stock-based compensation expense, merger-related and integration costs, and restructuring costs. 39 The undistributed earnings of our foreign subsidiaries amounted to approximately $2,194.1 million at December 31, 2023. Most of these earnings have been taxed in the U.S. under either the one-time tax on the deemed repatriation of undistributed foreign earnings (the “transition tax”), or the global intangible low-taxed income (“GILTI”) tax regime imposed by the Tax Cuts and Jobs Act of 2017. We have elected to pay the transition tax in installments over an eight year period, which ends in 2026. As of December 31, 2023, our remaining liability for the transition tax was $53.8 million. We continue to assert that the remaining undistributed earnings of our foreign subsidiaries are indefinitely reinvested. The distribution of earnings by our foreign subsidiaries in the form of dividends, or otherwise, may be subject to additional taxation. We estimate that additional taxes of approximately $119.3 million would be payable upon the remittance of all previously undistributed foreign earnings as of December 31, 2023, based upon the laws in effect on that date. We believe that we are able to maintain sufficient liquidity for our domestic operations and commitments without repatriating cash from our foreign subsidiaries. We finance our operating and investing needs primarily with borrowings under our Revolving Credit Facility and Receivables Facility, as well as uncommitted lines of credit entered into by certain of our foreign subsidiaries to support local operations, some of which are overdraft facilities. The Revolving Credit Facility has a borrowing limit of $1,725 million and the purchase limit under the Receivables Facility is $1,625 million. As of December 31, 2023, we had $953.0 million and $1,550.0 million outstanding under the Revolving Credit Facility and Receivables Facility, respectively. The maximum borrowing limits of our international lines of credit vary by facility and range between $0.6 million and $10.0 million. Our international lines of credit generally are renewable on an annual basis and certain facilities are fully and unconditionally guaranteed by Wesco Distribution. Accordingly, certain borrowings under these lines directly reduce availability under our Revolving Credit Facility. As of December 31, 2023, there was $8.2 million of borrowing capacity available under the international lines of credit that did not directly reduce availability under the Revolving Credit Facility. As of December 31, 2023, we had $1.0 million outstanding under our international lines of credit. On March 1, 2023, we repaid the $58.6 million aggregate principal amount of our 5.50% Anixter Senior Notes due 2023. The repayment was funded with borrowings under our Revolving Credit Facility and had no impact on our results of operations. Our $1,500 million of 7.125% Senior Notes will mature on June 15, 2025 (“2025 Notes”). On and after June 15, 2024, all or part of the 2025 Notes may be redeemed at a redemption price equal to 100% of the principal amount. We expect to complete a transaction or transactions to refinance the 2025 Notes during 2024. For information regarding amendments to the Receivables Facility and Revolving Credit Facility as well as disclosure of our debt instruments, including our outstanding indebtedness as of December 31, 2023, see Note 9, “Debt” of our Notes to Consolidated Financial Statements. An analysis of cash flows for 2023 and 2022 follows: Operating Activities Net cash provided by operating activities for 2023 totaled $493.2 million, compared to $11.0 million of cash generated in 2022. Net cash provided by operating activities for 2023 included net income of $766.1 million and non-cash adjustments to net income totaling $235.8 million, which primarily consisted of depreciation and amortization of $181.3 million, stock-based compensation expense of $48.1 million, and amortization of debt discount and debt issuance costs of $14.8 million, partially offset by deferred income taxes of $7.9 million. Other sources of cash in 2023 included a decrease in trade accounts receivable of $52.2 million due to the timing of receipts from customers and a decrease in net sales in the fourth quarter of 2023 compared to the fourth quarter of the prior year and a decrease in other accounts receivable of $3.6 million due primarily to the collection of supplier volume rebates earned in 2022 in excess of income accrued during the current period, partially offset by an increase in value-added tax receivables. Primary uses of cash in 2023 included a decrease in accounts payable of $319.7 million primarily due to a reduction in inventory purchases in the fourth quarter, a decrease in accrued payroll and benefit costs of $92.3 million resulting primarily from the payment of management incentive compensation earned in 2022, partially offset by the accrual of management incentive compensation earned in the current year. Net operating cash flow was also negatively impacted by $68.4 million from an increase in inventories. Inventories grew at a slower rate than sales, as supply chain lead times have normalized. Uses of cash in 2023 also included an increase in other current and noncurrent assets of $60.6 million primarily due to an increase in capitalized costs associated with 40 developing cloud computing arrangements to support our digital transformation initiatives, as well as ade crease in other current and noncurrent liabilities of $23.5 million. Net cash provided by operating activities for 2022 totaled $11.0 million. Net cash provided by operating activities for 2022 included net income of $862.1 million and non-cash adjustments to net income totaling $243.1 million, which primarily consisted of depreciation and amortization of $179.0 million, stock-based compensation expense of $46.4 million, and amortization of debt discount and debt issuance costs of $15.2 million, partially offset by deferred income taxes of $1.2 million. Other sources of cash in 2022 included an increase in accounts payable of $552.9 million due to higher purchases of inventory and an increase in other current and noncurrent liabilities of $131.6 million, primarily due to increases in deferred revenue and accrued taxes. Primary uses of cash in 2022 included an increase in inventories of $817.0 million due to supply chain challenges and to support growth in our sales backlog, including project-based business, an increase in trade accounts receivable of $690.6 million resulting from significant sales growth, an increase in other current and noncurrent assets of $153.2 million, primarily due to an increase in capitalized costs associated with developing cloud computing arrangements to support our digital transformation initiatives, an increase in other receivables of $54.8 million associated with higher supplier volume rebate income accruals, and a decrease in accrued payroll and benefit costs of $63.1 million due to lower incentive compensation accruals. Investing Activities Net cash used in investing activities in 2023 was $89.6 million, compared to $283.6 million in 2022. Included in 2023 were capital expenditures of $92.3 million which primarily consisted of internal-use computer software and information technology hardware to support our digital transformation initiatives, as well as equipment and leasehold improvements to support our global network of branches, warehouses and sales offices. Net cash used in investing activities in 2022 was $283.6 million. Included in 2022 was $255.4 million of cash paid to acquire Rahi Systems, less cash acquired of $68.6 million, as described in Note 6, “Acquisitions and Disposals” of our Notes to Consolidated Financial Statements. Capital expenditures were $99.4 million in 2022. Financing Activities Net cash used in financing activities in 2023 was $403.9 million, compared to $584.0 million of net cash provided by financing activities in 2022. During 2023, financing activities primarily consisted of net repayments of $70.3 million related to our Revolving Credit Facility and the repayment of our $58.6 million aggregate principal amount of 5.50% Anixter Senior Notes due 2023, partially offset by net borrowings of $15.0 million related to our Receivables Facility. Financing activities for 2023 also included $76.6 million and $57.4 million of dividends paid to holders of our common stock and Series A Preferred Stock, respectively, $75.0 million of common stock repurchases, $68.3 million of payments for taxes related to the exercise and vesting of stock-based awards, and net repayments on our various international lines of credit of approximately $6.0 million. Net cash provided by financing activities in 2022 was $584.0 million. During 2022, financing activities primarily consisted of net borrowings of $433.0 million related to our Revolving Credit Facility and net borrowings of $265.0 million related to our Receivables Facility. Financing activities for 2022 also included $57.4 million of dividends paid to holders of our Series A Preferred Stock, $25.8 million of payments for taxes related to the exercise and vesting of stock-based awards, borrowings and repayments of $19.5 million and $19.5 million, respectively, related to our various international lines of credit, and $11.1 million of common stock repurchases. The following table summarizes our material cash requirements from known contractual and other obligations at December 31, 2023, including interest, and the expected effect on our liquidity and cash flow in future periods: 2024 2025 to 2026 2027 to 2028 2029 - After Total (In millions) Debt, excluding debt discount and debt issuance costs $ Interest on indebtedness(1) Non-cancelable operating leases Transition tax installments Defined benefit pension plans(2) Total $ 8.6 365.4 191.2 16.1 7.0 588.3 $ $ 3,070.0 393.5 319.0 37.7 — 3,820.2 $ $ 2,284.5 155.0 206.4 — — 2,645.9 $ $ 1.5 — 188.8 — — 190.3 $ $ 5,364.6 913.9 905.4 53.8 7.0 7,244.7 41 (1) Interest on variable rate debt was calculated using the rates and balances outstanding at December 31, 2023. (2) As disclosed in Note 13, “Employee Benefit Plans” of our Notes to Consolidated Financial Statements, the majority of our various defined benefit pension plans are non-contributory and, with the exception of the U.S. and Canada, cover substantially all full-time employees in their respective countries. Retirement benefits are provided based on compensation as defined in the plans. Our policy is to fund these plans as required by the Employee Retirement Income Security Act, the Internal Revenue Service and local statutory law. We currently estimate that we will contribute $7.0 million to our foreign pension plans in 2024. Due to the future impact of various market conditions, rates of return and changes in plan participants, we cannot provide a meaningful estimate of our future contributions beyond 2024. In addition to the cash requirements disclosed in the table above, we expect future uses of cash to include working capital requirements, capital expenditures, investments in our digital capabilities, dividend payments to holders of our common stock and Series A Preferred Stock, benefit payments to participants in our deferred compensation plan, and other organic opportunities. Future uses of cash could also include acquisitions of businesses and the repurchase of common or preferred stock. We expect to spend approximately $100 million in 2024 on capital expenditures for information technology investments and to support our global network of branches, warehouses and sales offices. We expect to fund future uses of cash with a combination of existing cash balances, cash generated from operating activities, borrowings under our revolving credit and accounts receivable securitization facilities, or new issuances of debt. Purchase orders for inventory requirements and service contracts are not included in the table above. Generally, our purchase orders and contracts contain clauses allowing for cancellation. We do not have significant agreements to purchase material or goods that would specify minimum order quantities. Liabilities related to unrecognized tax benefits, including interest and penalties, of $133.7 million were excluded from the table above as we cannot reasonably estimate the timing of these potential cash settlements with taxing authorities. See Note 11, “Income Taxes” in our Notes to Consolidated Financial Statements for further information related to unrecognized tax benefits. Seasonality Our operating results are not significantly affected by seasonal factors. Sales during the first and fourth quarters have historically been affected by a reduced level of activity due to the impact of weather on projects. Sales typically increase beginning in March, with slight fluctuations per month through October. During periods of economic expansion or contraction, our sales by quarter have varied significantly from this pattern. Recent Accounting Standards See Note 2, “Accounting Policies” of our Notes to Consolidated Financial Statements for a description of recently adopted and recently issued accounting standards.

Foreign Currency Risks In 2023, approximately 26% of our sales were from our foreign subsidiaries and are denominated in foreign currencies. Our exposure to currency rate fluctuations primarily relate to Canada (Canadian dollar), certain countries in the European Union (euro), the United Kingdom (British pound), Sweden (Swedish krona), Switzerland (Swiss franc), and Australia (Australian dollar). We also have exposure to currency rate fluctuations related to more volatile markets including Argentina (peso), Brazil (real), Chile (peso), Colombia (peso), Egypt (pound), Mexico (peso), and Turkey (lira). We may establish additional foreign subsidiaries in the future. Accordingly, we may derive alarg er portion of our sales from international operations, and a portion of these sales may be denominated in foreign currencies. As a result, our future operating results could be subject to further fluctuations in foreign exchange rates relative to the U.S. dollar. Furthermore, to the extent that we engage in international sales denominated in U.S. dollars, an increase in the value of the U.S. dollar relative to foreign currencies could make our products less competitive in international markets. 42 We purchase foreign currency forward contracts to reduce the effect of fluctuating foreign currency-denominated accounts on our reported earnings. The foreign currency forward contracts are not designated as hedges for accounting purposes. At December 31, 2023 and 2022, the gross and net notional amounts of foreign currency forward contracts outstanding were approximately $168.4 million and $172.8 million, respectively. We prepared a sensitivity analysis of our foreign currency forward contracts assuming a10 % adverse change in the value of foreign currency contracts outstanding. The hypothetical adverse changes would have resulted in recording a $16.8 million and $17.3 million loss in 2023 and 2022, respectively. However, since these forward contracts are intended to be effective economic hedges, we would record offsetting gains as a result of the remeasurement of the underlying foreign currency denominated monetary amounts being hedged. Interest Rate Risk Fixed Rate Borrowings: As of December 31, 2023, approximately 53% of our debt portfolio comprises fixed rate debt. As our 6.00% Anixter Senior Notes due 2025, 7.125% Senior Notes due 2025, and 7.250% Senior Notes due 2028 were issued at fixed rates, interest expense would not be impacted by interest rate fluctuations. However, the fair value of our fixed rate debt will generally fluctuate with movements of interest rates, increasing in periods of declining rates of interest and declining in periods of increasing rates of interest. The fair value of our debt instruments with fixed interest rates is disclosed in Note 4, “Fair Value of Financial Instruments” of our Notes to Consolidated Financial Statements. Floating Rate Borrowings: Our variable rate borrowings comprise the Revolving Credit Facility, the Receivables Facility, and international lines of credit. The fair value of these debt instruments at December 31, 2023 approximated carrying value. We borrow under our Revolving Credit Facility and Receivables Facility for general corporate purposes, including working capital requirements and capital expenditures. As disclosed in Note 9, “Debt” of our Notes to Consolidated Financial Statements, these facilities were amended during 2022 to, among other things, replace the respective LIBOR-based interest rate options with SOFR- based interest rate options, including term SOFR and daily simple SOFR. The use of SOFR in place of LIBOR for such facilities has not had a material impact on our results from operations. A 100 basis point rise or decline in interest rates would result in an increase or decrease to interest expense of $25.2 million under our current capital structure. 43 Item 8. Financial Statements and Supplementary Data. The information required by this item is set forth in our Consolidated Financial Statements contained in this Annual Report on Form 10-K. Specific financial statements can be found at the pages listed below: Report of Independent Registered Public Accounting Firm (PCAOB ID 238) Consolidated Balance Sheets as of December 31, 2023 and 2022 Consolidated Statements of Income and Comprehensive Income for the years ended December 31, 2023, 2022 and 2021 Consolidated Statements of Stockholders’ Equity for the years ended December 31, 2023, 2022 and 2021 Consolidated Statements of Cash Flows for the years ended December 31, 2023, 2022 and 2021 Notes to Consolidated Financial Statements PAGE 45 47 48 49 50 51 44 Report of Independent Registered Public Accounting Firm To the Board of Directors and Stockholders of WESCO International, Inc. Opinions on the Financial Statements and Internal Control over Financial Reporting We have audited the accompanying consolidated balance sheets of WESCO International, Inc. and its subsidiaries (the “Company”) as of December 31, 2023 and 2022, and the related consolidated statements of income and comprehensive income, of stockholders’ equity and of cash flows for each of the three years in the period ended December 31, 2023, including the related notes and schedule of valuation and qualifying accounts for each of the three years in the period ended December 31, 2023 appearing under Item 15 (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO. Basis for Opinions The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on ate st basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. 45 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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Critical Audit Matters The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as awh ole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Revenue Recognition As described in Note 2 to the consolidated financial statements, the Company’s revenue arrangements generally consist of single performance obligations to transfer a promised good or service, or a combination of goods and services. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring goods or providing services. Revenue is recognized when control has transferred to the customer, which is generally when the product has shipped from the Company’s facility or directly from a supplier. For the year ended December 31, 2023, the Company’s net sales were $22,385 million. The principal consideration for our determination that performing procedures relating to revenue recognition is a critical audit matter is the significant audit effort in performing procedures related to the Company’s revenue recognition. Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the revenue recognition process. These procedures also included, among others, for certain components, evaluating revenue transactions on a sample basis by inspecting evidence of consideration received in exchange for transferring goods, and for other components, (i) evaluating revenue transactions by testing the issuance and settlement of invoices and credit memos, (ii) tracing transactions not settled to a detailed listing of accounts receivable, (iii) confirming a sample of outstanding customer invoice balances at year end and obtaining and inspecting source documents, including invoices, sales contracts, and subsequent cash receipts, where applicable, for confirmations not returned, and (iv) testing the completeness and accuracy of data provided by management. /s/ PricewaterhouseCoopers LLP Pittsburgh, Pennsylvania February 20, 2024 We have served as the Company’s auditor since 1994. 46 WESCO INTERNATIONAL, INC.

All intercompany accounts and transactions have been eliminated in consolidation. In the first quarter of the fiscal year ended December 31, 2023, we changed our presentation in tables from thousands to millions. Certain amounts as of December 31, 2023 and 2022 and for the years ended December 31, 2023, 2022 and 2021 in the consolidated financial statements and associated notes may not foot or recalculate due to rounding. Reclassifications The Consolidated Statements of Cash Flows and the reconciliation between the federal statutory income tax rate and the effective tax rate in Note 11, “Income Taxes” for the years ended December 31, 2022 and 2021, respectively, include certain reclassifications to previously reported amounts to conform to the current period's presentation. Such reclassifications had no impact on the totals of operating, investing and financing cash flow activities or the effective tax rates for those years. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Although these estimates are based on management’s best knowledge of current events and actions Wesco may undertake in the future, actual results may ultimately differ from the estimates. Revenue Recognition Wesco’s revenue arrangements generally consist of single performance obligations to transfer a promised good or service, or a combination of goods and services. Revenue is measured as the amount of consideration Wesco expects to receive in exchange for transferring goods or providing services. Revenue is recognized when control has transferred to the customer, which is generally when the product has shipped from a Wesco facility or directly from a supplier. However, transfer may occur at ala ter date depending on the agreed upon terms, such as delivery at the customer's designated location, or based on consignment terms. For products that ship directly from suppliers to customers, Wesco generally acts as the principal in the transaction and recognizes revenue on a gross basis. When providing services, sales are recognized over time as control transfers to the customer, which occurs as services are rendered. Wesco generally satisfies its performance obligations within a year or less. Wesco generally does not have significant financing terms associated with its contractual arrangements; payments are normally received within 60 days. There are generally no significant costs associated with obtaining customer contracts. Wesco typically passes through warranties offered by manufacturers or suppliers to its customers. Sales taxes (and value added taxes in foreign jurisdictions) collected from customers and remitted to governmental authorities are excluded from net sales. Supplier Volume Rebates Wesco receives volume rebates from certain suppliers based on contractual arrangements with such suppliers. Volume rebates are included within other receivables in the Consolidated Balance Sheets, and represent the estimated amounts due to Wesco based on forecasted purchases and the rebate provisions of the various supplier contracts. The corresponding rebate income is 51 WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) recorded as a reduction to cost of goods sold. Receivables under the supplier rebate program were $233.1 million at December 31, 2023 and $246.2 million at December 31, 2022. Supplier volume rebate income as a percentage of net sales was 1.4% in 2023, 1.6% in 2022 and 1.4% in 2021. Supplier Finance Programs The Company has supplier finance programs that are administered by intermediaries. Under these arrangements, participating suppliers may elect to receive early payment of invoices that have been confirmed by the Company, less an interest deduction or fees paid by the supplier, which is paid to the supplier by third-party finance providers. Wesco agrees to pay the stated amount of confirmed invoices in full on the original due date of the invoices, which is typically within 45 to 180 days of the invoice date, regardless of whether the supplier elects to receive early payment from the third-party finance providers. The Company does not provide assets pledged as security or other forms of guarantees to the finance providers or intermediaries under these arrangements. As of December 31, 2023 and 2022, the amounts due to suppliers that participate in the Company's supplier finance programs were approximately $32.6 million and $30.7 million, respectively, which are included in accounts payable in the Consolidated Balance Sheets. Cash and Cash Equivalents Cash equivalents are defined as highly liquid investments with original maturities of 90 days or less when purchased. Cash and cash equivalents in the Consolidated Balance Sheets include $21.9 million and $21.2 million as of December 31, 2023 and 2022, respectively, that is restricted from use to fund operations. Allowance for Expected Credit Losses Wesco recognizes expected credit losses resulting from the inability of its customers to make required payments through an allowance account that is measured each reporting period. Wesco estimates credit losses over the life of its trade accounts receivable using a combination of historical loss data, current credit conditions, specific customer circumstances, and reasonable and supportable forecasts of future economic conditions. The allowance for expected credit losses was $55.9 million at December 31, 2023 and $46.5 million at December 31, 2022. The total amount recorded as selling, general and administrative expense related to credit losses was $18.6 million, $18.0 million and $12.9 million for 2023, 2022 and 2021, respectively. Inventories Inventories primarily consist of merchandise purchased for resale and are stated at the lower of cost or net realizable value. Cost is determined principally under the average cost method. Wesco reduces the carrying value of its inventories at the earlier of identifying an item that is considered to be obsolete or in excess of supply relative to demand, or no movement in a prescribed number of months. The carrying value of inventories reflect reductions for excess and obsolescence of $113.4 million and $70.0 million at December 31, 2023 and 2022, respectively. The total expense related to excess and obsolete inventories, which is included in cost of goods sold, was $63.1 million, $43.2 million and $37.1 million for 2023, 2022 and 2021, respectively. Property, Buildings and Equipment Property, buildings and equipment are recorded at cost. Depreciation expense is determined using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized over either their respective lease terms or their estimated lives, whichever is shorter. Estimated useful lives range from five to forty years for buildings and leasehold improvements and three to eight years for furniture, fixtures and equipment. Costs incurred during the application development stage of internally developed software are capitalized and are reported at the lower of unamortized cost or net realizable value. Costs incurred during the preliminary project and post-implementation stages are expensed as incurred. Capitalized costs include external direct costs of materials and services consumed in developing internal-use computer software, payroll and payroll-related costs for employees who are directly associated with and who devote time to the internal-use computer software project, as well as interest costs. Internal-use computer software is amortized using the straight-line method over its estimated useful life, typically three to seven years. 52 WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) Expenditures for new facilities and improvements that extend the useful life of an asset are capitalized. Ordinary repairs and maintenance are expensed as incurred. When property is retired or otherwise disposed, the cost and the related accumulated depreciation are removed from the accounts and any resulting gains or losses are recorded and reported as selling, general and administrative expenses. Of Wesco’s $423.6 million net book value of property, buildings and equipment as of December 31, 2023, $152.8 million consists of land, buildings and leasehold improvements that are geographically dispersed among Wesco’s nearly 800 branches, warehouses and sales offices, mitigating the risk of impairment. Wesco assesses its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of any such assets may not be fully recoverable. Changes in circumstances include, among others, technological advances, changes in the business model, capital structure, economic conditions or operating performance. The evaluation is based upon, among other things, utilization, serviceability and assumptions developed by management, which are categorized as Level 3 of the fair value hierarchy, related to the estimated future undiscounted cash flows that these assets are expected to generate. When the sum of the undiscounted cash flows is less than the carrying value of the asset (asset group), an impairment loss is recognized to the extent that carrying value exceeds fair value. Management applies its best judgment when performing these evaluations. Leases The determination of whether an arrangement is, or contains, alease i s performed at the inception of the arrangement. Classification and initial measurement of the right-of-use asset and lease liability are determined at the lease commencement date. The Company has elected the short-term lease measurement and recognition exemption; therefore, leases with an initial term of twelve months or less are not recorded on the balance sheet. Operating lease expense is recognized on a straight-line basis over the lease term. Operating lease assets and liabilities are recognized at the commencement date based on the present value of the future minimum lease payments. Certain leases contain rent escalation clauses that are either fixed or adjusted periodically for inflation or market rates and such clauses are factored into the Company's determination of lease payments. Wesco also has variable lease payments that do not depend on a rate or index, primarily for items such as common area maintenance and real estate taxes, which are recorded as variable expense when incurred. The operating lease asset includes advance payments and excludes incentives and initial direct costs incurred. The Company's arrangements include certain non-lease components such as common area and other maintenance for leased real estate, as well as mileage, fuel and maintenance costs related to leased automobiles and trucks. Wesco accounts for these non-lease components separately from the associated lease components. The Company does not guarantee any residual value in its lease agreements, and there are no material restrictions or covenants imposed by lease arrangements. Real estate leases typically include one or more options to extend the lease, or terminate early. The Company regularly evaluates the renewal options, and when they are reasonably certain of exercise, the Company includes the renewal period in its lease term. For most of Wesco’s leases, the discount rate implicit in the lease is not readily determinable. Accordingly, the Company uses its incremental borrowing rate on a secured basis based on the information available at the lease commencement date to discount lease payments to the present value. 53 WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) Goodwill and Indefinite-Lived Intangible Assets Goodwill and indefinite-lived intangible assets are tested for impairment annually as of October 1, or more frequently if triggering events occur, indicating that their carrying value may not be recoverable. Wesco tests for goodwill impairment on a reporting unit level. The Company first assesses qualitative factors, including macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, other relevant events such as changes in key personnel, changes in the composition or carrying amount of the net assets of a reporting unit, and changes in share price, to determine whether it is more likely than not that the fair value of Wesco's reporting units are less than their carrying values. If the qualitative assessment indicates that the fair values of the Company's reporting units may not exceed their respective carrying values, then Wesco performs aqua ntitative test for impairment by comparing the fair value of each reporting unit to its carrying value. The Company determines the fair values of its reporting units using a discounted cash flow analysis and consideration of market multiples. The discounted cash flow analysis uses certain assumptions, including expected operating margins supported by a combination of historical results, current forecasts, market data and recent economic events, which are categorized within Level 3 of the fair value hierarchy. The Company uses a discount rate that reflects market participants' cost of capital. Wesco evaluates the recoverability of indefinite-lived intangible assets using the relief-from-royalty method based on projected financial information. Significant inputs used in the relief-from-royalty method include projected revenues, discount rates, royalty rates, and applicable income tax rates. At December 31, 2023 and 2022, goodwill and indefinite-lived trademarks totaled $4.1 billion and $4.0 billion, respectively. The determination of fair value involves significant management judgment, particularly as it relates to the underlying assumptions and factors around future expected operating margins and discount rate. Management applies its best judgment when assessing the reasonableness of financial projections. Fair values are sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of the annual goodwill and indefinite- lived intangible impairment tests will prove to be an accurate prediction of future results. Definite-Lived Intangible Assets Definite-lived intangible assets are amortized over 5 to 20 years. Certain customer relationships are amortized using an accelerated method whereas all other definite-lived intangible assets subject to amortization use a straight-line method. In either case, the amortization method reflects the pattern in which the economic benefits of the respective assets are consumed or otherwise used. Wesco continually evaluates whether events or circumstances have occurred that would indicate the remaining estimated useful lives of definite-lived intangible assets require revision or that the remaining carrying value of such assets may not be recoverable. Cloud Computing Arrangements The Company capitalizes costs associated with implementing its various cloud computing arrangements. Capitalized implementation costs, which are recorded as a component of other assets in the Consolidated Balance Sheets, were $195.4 million and $104.1 million as of December 31, 2023 and 2022, respectively, and the related accumulated amortization was $15.5 million and $6.1 million, respectively. Insurance Programs Wesco uses commercial insurance for auto, workers’ compensation, casualty and health claims, and information technology as a risk-reduction strategy to minimize catastrophic losses. The Company’s strategy involves large deductible policies where Wesco must pay all costs up to the deductible amount. Wesco estimates the reserve for these programs based on historical incident rates and costs. The assumptions included in developing this accrual include the period of time between the incurrence and payment of a claim. The total liability related to insurance programs was $28.1 million and $28.0 million at December 31, 2023 and 2022, respectively. Income Taxes Wesco accounts for income taxes under the asset and liability method, which requires the recognition of deferred income taxes for events that have future tax consequences. Under this method, deferred income taxes are recognized (using enacted tax laws and rates) based on the future income tax effects of differences in the carrying amounts of assets and liabilities for financial 54 WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) reporting and tax purposes. The effect of a tax rate change on deferred tax assets and liabilities is recognized in income in the period of change. Wesco recognizes deferred tax assets consistent with amounts expected to be realized. To make such determination, management evaluates all positive and negative evidence, including but not limited to, prior, current and future taxable income, tax planning strategies and future reversals of existing taxable temporary differences. A valuation allowance is recognized if it is “more-likely-than-not” that some or all of a deferred tax asset will not be realized. Wesco regularly assesses the realizability of deferred tax assets. Wesco accounts for uncertainty in income taxes using a “more-likely-than-not” recognition threshold. Due to the subjectivity inherent in the evaluation of uncertain tax positions, the tax benefit ultimately recognized may materially differ from the estimate recognized in the consolidated financial statements. Wesco recognizes interest and penalties related to uncertain tax benefits as part of interest expense and income tax expense, respectively. The Tax Cuts and Jobs Act of 2017 (the “TCJA”) imposed a one-time tax on the deemed repatriation of undistributed foreign earnings (the “transition tax”). Except for a portion of foreign earnings previously taxed in the U.S. that can effectively be distributed without further material U.S. or foreign taxation, the Company continues to assert that the undistributed earnings of its foreign subsidiaries are indefinitely reinvested. To the extent the earnings of the Company's foreign subsidiaries are distributed in the form of dividends, such earnings may be subject to additional taxes. The Company believes that it is able to maintain a sufficient level of liquidity for its domestic operations and commitments without incurring any material tax cost to repatriate cash held by its foreign subsidiaries. The provisions of the TCJA also introduced U.S. taxation on certain global intangible low-taxed income (“GILTI”). Wesco has elected to account for GILTI tax as a component of income tax expense. Foreign Currency The functional currency for most of the Company's operations outside the U.S. is generally the applicable local currency. Assets and liabilities of these operations are translated to U.S. dollars at the exchange rate in effect at the end of each period. Income statement accounts are translated at an exchange rate that approximates the average for the period. Translation adjustments arising from the use of differing exchange rates from period to period are included as a component of other comprehensive income (loss) within stockholders’ equity. Gains and losses from foreign currency transactions are included in net income for the period. The Company may re-evaluate the functional currencies of certain operations outside the U.S. if there are significant changes to operations that indicate that a change in functional currency may be necessary. Defined Benefit Pension Plans Liabilities and expenses for defined benefit pension plans are determined using actuarial methodologies and incorporate significant assumptions, including the interest rate used to discount the future estimated cash flows, the expected long-term rate of return on plan assets, and several assumptions relating to the employee workforce (salary increases, retirement age, and mortality). Unrealized gains and losses related to the Company's defined benefit pension obligations are recognized as a component of other comprehensive income (loss) within stockholders' equity. Gains or losses resulting from plan amendments, curtailments, and settlements are recognized as a component of other non-operating income and expenses (“other expense (income), net”) in the period of the remeasurement. Fair Value of Financial Instruments The Company measures the fair value of assets and liabilities on a recurring and nonrecurring basis according to a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of the fair value hierarchy are as follows: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that are accessible at the measurement date; Level 2 inputs include inputs other than Level 1 that are observable, either directly or indirectly, and Level 3 inputs are unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to measurements involving significant unobservable inputs (Level 3). 55 WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) The Company measures the fair values of goodwill, intangible assets and property, buildings and equipment on a nonrecurring basis if required by impairment tests applicable to these assets, as described above. Other, net Other non-operating income and expenses (“other expense (income), net”) primarily includes the non-service cost components of net periodic pension cost (benefit) and foreign exchange gains and losses. Recently Adopted and Recently Issued Accounting Standards In September 2022, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2022-04, Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations, which requires that a buyer in a supplier finance program disclose sufficient information about the program to allow aus er of financial statements to understand the program's nature, activity during the period, changes from period to period, and potential magnitude. The amendments in this ASU are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, except for the amendment on rollforward information, which is effective for fiscal years beginning after December 15, 2023. The Company adopted this ASU in the first quarter of 2023, except for the amendment on rollforward information, which the Company will begin disclosing in its Annual Report on Form 10-K for the fiscal year ending December 31, 2024. The adoption of this ASU resulted in additional disclosure of the Company's supplier finance programs. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which enhances prior reportable segment disclosure requirements in part by requiring entities to disclose significant expenses related to their reportable segments. The amendments in this ASU are effective on a retrospective basis for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Management is currently evaluating the impact that this accounting standard will have on its consolidated financial statements and notes thereto. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this ASU are effective for annual periods beginning after December 15, 2024 on a prospective basis. Management is currently evaluating the impact that this accounting standard will have on its consolidated financial statements and notes thereto. Other pronouncements issued by the FASB or other authoritative accounting standards groups with future effective dates are either not applicable or are not expected to be significant to Wesco’s financial position, results of operations or cash flows. 3. REVENUE Wesco distributes products and provides services to customers globally in various end markets within its business segments. The segments, which consist of EES, CSS and UBS operate in the United States, Canada and various other countries. The following tables disaggregate Wesco’s net sales by segment and geography for the periods presented: (In millions) Electrical & Electronic Solutions Communications & Security Solutions Utility & Broadband Solutions Total by segment Year Ended December 31, 2023 2022 2021 $ $ 8,610.3 $ 8,823.3 $ 7,152.2 6,622.7 22,385.2 $ 6,401.5 6,195.3 21,420.1 $ 7,621.3 5,715.2 4,881.0 18,217.5 56 WESCO INTERNATIONAL, INC.

(2) Wesco attributes revenues from external customers to individual countries on the basis of point of sale. Due to the terms of certain contractual arrangements, Wesco bills or receives payment from its customers in advance of satisfying the respective performance obligation. Such advance billings or payments are recorded as deferred revenue and recognized as revenue when the performance obligation has been satisfied and control has transferred to the customer, which is generally upon shipment. Deferred revenue is usually recognized within a year or less from the date of the advance billing or payment. At December 31, 2023 and 2022, $111.9 million and $99.6 million, respectively, of deferred revenue was recorded as a component of other current liabilities in the Consolidated Balance Sheets. The Company recognized $74.0 million of revenue during 2023 that was included in the deferred revenue balance as of December 31, 2022. The amount of revenue recognized during 2022 and 2021 that was deferred as of December 31, 2021 and 2020, respectively, was not material. The Company also has certain long-term contractual arrangements where revenue is recognized over time based on the cost- to-cost input method. As of December 31, 2023 and 2022, the Company had contract assets of $35.4 million and $27.5 million, respectively, resulting from contracts where the amount of revenue recognized exceeded the amount billed to the customer. Contract assets are recorded in the Consolidated Balance Sheets as aco mponent of prepaid expenses and other current assets. Wesco’s revenues are adjusted for variable consideration, which includes customer volume rebates, returns and discounts. Wesco measures variable consideration by estimating expected outcomes using analysis and inputs based upon historical data, as well as current and forecasted information. Variable consideration is reviewed by management on a monthly basis and revenue is adjusted as necessary. Variable consideration reduced revenue for the years ended December 31, 2023, 2022 and 2021 by approximately $427.8 million, $417.1 million and $360.6 million, respectively. As of December 31, 2023 and 2022, the Company's estimated product return obligation was $41.3 million and $46.5 million, respectively. Billings to customers for shipping and handling are recognized in net sales. Wesco has elected to recognize shipping and handling costs as a fulfillment cost. Shipping and handling costs recorded as a component of selling, general and administrative expenses totaled $306.8 million, $302.3 million and $248.3 million for the years ended December 31, 2023, 2022 and 2021, respectively. 4. FAIR VALUE OF FINANCIAL INSTRUMENTS The Company’s financial instruments primarily consist of cash and cash equivalents, accounts receivable, accounts payable, bank overdrafts, outstanding indebtedness, foreign currency forward contracts, and benefit plan assets. The fair value of the Company's benefit plan assets is disclosed in Note 13, “Employee Benefit Plans” and except for outstanding indebtedness and foreign currency forward contracts, the carrying value of the Company’s remaining financial instruments approximates fair value. The Company uses a market approach to determine the fair value of its debt instruments, utilizing quoted prices in active markets, interest rates and other relevant information generated by market transactions involving similar instruments. Therefore, the inputs used to measure the fair value of the Company's debt instruments are classified as Level 2 within the fair value hierarchy. The carrying value of Wesco's debt instruments with fixed interest rates was $2,823.7 million and $2,881.2 million as of December 31, 2023 and 2022, respectively. The estimated fair value of this debt was $2,880.3 million and $2,929.5 million as of December 31, 2023 and 2022, respectively. The reported carrying values of Wesco's other debt instruments, including those with variable interest rates, approximated their fair values as of December 31, 2023 and 2022. 57 WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) The Company purchases foreign currency forward contracts to reduce the effect of fluctuations in foreign currency- denominated accounts on its earnings. The foreign currency forward contracts are not designated as hedges for accounting purposes. The Company's strategy is to negotiate terms for its derivatives and other financial instruments to be highly effective, such that the change in the value of the derivative offsets the impact of the underlying hedge. Its counterparties to foreign currency forward contracts have investment-grade credit ratings. The Company regularly monitors the creditworthiness of its counterparties to ensure no issues exist that could affect the value of its derivatives. The Company does not hedge 100% of its foreign currency-denominated accounts. In addition, the results of hedging can vary significantly based on various factors, such as the timing of executing foreign currency forward contracts versus the movement of currencies, as well as fluctuations in the account balances throughout each reporting period. The fair value of foreign currency forward contracts is based on the difference between the contract rate and the current price of a forward contract with an equivalent remaining term. The fair value of foreign currency forward contracts is measured using observable market information. These inputs are considered Level 2 in the fair value hierarchy. At December 31, 2023 and 2022, foreign currency forward contracts were revalued at then-current foreign exchange rates with the changes in valuation reflected directly in other non-operating expense (income) in the Consolidated Statements of Income and Comprehensive Income offsetting the transaction gain (loss) recorded on foreign currency-denominated accounts. At December 31, 2023 and 2022, the gross and net notional amounts of foreign currency forward contracts outstanding were approximately $168.4 million and $172.8 million, respectively. While all of the Company's foreign currency forward contracts are subject to master netting arrangements with its counterparties, assets and liabilities related to these contracts are presented on a gross basis within the Consolidated Balance Sheets. The gross fair value of assets and liabilities related to foreign currency forward contracts were immaterial. 5. GOODWILL AND INTANGIBLE ASSETS The following table sets forth the changes in the carrying value of goodwill by reportable segment for the periods presented: (In millions) Balance as of December 31, 2021 Adjustments to goodwill for acquisitions(1) Foreign currency exchange rate changes Balance as of December 31, 2022 Adjustments to goodwill for acquisitions(1) Foreign currency exchange rate changes Balance as of December 31, 2023 EES CSS UBS Total $ $ $ 861.0 $ — (35.5) 825.5 $ — 12.6 838.1 $ 1,121.7 $ 97.4 (10.2) 1,208.9 $ 0.9 1.8 1,211.6 $ 1,225.7 — (19.1) 1,206.5 — 6.1 1,212.6 $ $ $ 3,208.3 97.4 (64.8) 3,240.9 0.9 20.5 3,262.3 (1) Adjustments to goodwill reflect the preliminary allocation of the purchase price paid to acquire Rahi Systems, which is part of the CSS segment, and adjustments to the assets acquired and liabilities assumed since their initial measurement, as disclosed in Note 6, “Acquisitions and Disposals”.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) (1) Excludes the original cost and related accumulated amortization of fully-amortized intangible assets. Amortization expense related to intangible assets totaled $88.6 million, $92.9 million and $119.6 million for the years ended December 31, 2023, 2022 and 2021, respectively. The following table sets forth the remaining estimated amortization expense for intangible assets for the next five years and thereafter: For the year ending December 31, (In millions) 2024 2025 2026 2027 2028 Thereafter $ 86.3 83.2 77.8 74.9 73.2 669.2 The Company performed its annual impairment tests of goodwill and indefinite-lived intangible assets during the fourth quarter of 2023 by assessing qualitative factors to determine whether it was more likely than not that the fair values of its reporting units and indefinite-lived intangible assets were less than their respective carrying amounts. In performing this qualitative assessment, the Company assessed relevant events and circumstances, including macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, other relevant events such as changes in key personnel, changes in the composition or carrying amount of the net assets of a reporting unit, and changes in share price. As a result of this assessment, the Company determined that it was more likely than not that the fair values of its reporting units and indefinite-lived intangible assets continued to exceed their respective carrying amounts and, therefore, aqua ntitative impairment test was not necessary. The annual impairment tests of goodwill and indefinite-lived intangible assets involve the assessment of factors, events and circumstances at apoi nt in time that are subject to change. As a result, there can be no assurance that the fair values of the Company's reporting units and indefinite-lived intangible assets will exceed their carrying values in the future, and that goodwill and indefinite-lived intangible assets will be fully recoverable. 6. ACQUISITIONS AND DISPOSALS Rahi Systems Holdings, Inc. On November 1, 2022, through its wholly-owned subsidiary WESCO Distribution, Inc. (“Wesco Distribution”), the Company acquired 100% of the equity securities of Rahi Systems Holdings, Inc. (“Rahi Systems” or “Rahi”). Headquartered in Fremont, California, Rahi Systems is ale ading provider of global hyperscale data center solutions with over 900 employees in 25 countries.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) The purchase consideration was allocated to the identified assets acquired and liabilities assumed based on their respective acquisition date fair value, with the excess allocated to goodwill. The Company identified acu stomer relationship intangible asset and estimated its fair value using an income valuation method. The excess purchase consideration recorded as goodwill is not deductible for income tax purposes, and has been assigned to the Company's CSS reportable segment, as disclosed in Note 5, “Goodwill and Intangible Assets”. The resulting goodwill is primarily attributable to Rahi’s workforce and cross-selling opportunities in additional geographies. The estimated fair values of assets acquired and liabilities assumed were based on preliminary calculations and valuations using estimates and assumptions at the time of acquisition. During the fourth quarter of 2023, the Company finalized its allocation of the purchase consideration to the respective fair values of assets acquired and liabilities assumed in the acquisition of Rahi. As the Company obtained additional information during the measurement period, it recorded adjustments to its preliminary estimates of fair value, which were as of November 1, 2022. As presented in the table below, the net impact of these measurement period adjustments was an increase to goodwill of $0.9 million. The results of operations of Rahi Systems are included in the consolidated financial statements beginning on November 1, 2022, the acquisition date. For the years ended December 31, 2023 and 2022, the Consolidated Statements of Income and Comprehensive Income include $543.9 million and $111.5 million of net sales, respectively, and an immaterial amount of income from operations for Rahi Systems. The Company has not presented supplemental pro forma revenue and earnings of the combined business as the acquisition of Rahi Systems is not material to Wesco's consolidated financial statements. 60 WESCO INTERNATIONAL, INC.

International Lines of Credit Certain foreign subsidiaries of Wesco have entered into uncommitted lines of credit, some of which are overdraft facilities, to support local operations. The maximum borrowing limit varies by facility and ranges between $0.6 million and $10.0 million. The international lines of credit generally are renewable on an annual basis and certain facilities are fully and unconditionally guaranteed by Wesco Distribution. Accordingly, certain borrowings under these lines directly reduce availability under the Company's revolving credit facility. The applicable interest rate for borrowings under these lines of credit varies by country and is governed by the applicable loan agreement. The average interest rate for these facilities was 0.85% and 4.84% at December 31, 2023 and 2022, respectively. Accounts Receivable Securitization Facility Wesco Distribution has an accounts receivable securitization facility (the “Receivables Facility”) pursuant to the terms and conditions of a Fifth Amended and Restated Receivables Purchase Agreement (the “Receivables Purchase Agreement”), by and among WESCO Receivables Corp. (“Wesco Receivables”), Wesco Distribution, the various purchaser groups from time to time party thereto and PNC Bank, National Association, as Administrator, dated as of June 22, 2020. The Receivables Purchase Agreement amended and restated the receivables purchase agreement entered into on September 24, 2015 (the “Prior Receivables Purchase Agreement”). As of December 31, 2023, the Receivables Facility has apu rchase limit of $1,625 million, with the opportunity to exercise an accordion feature that permits increases in the purchase limit up to an aggregate commitment of $1,750 million, subject to customary conditions, and a maturity date of March 1, 2025. The Receivables Facility has an interest rate spread of 1.05% and a commitment fee of 0.45%. 64 WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) As of December 31, 2023 and 2022, accounts receivable eligible for securitization totaled $2,146.9 million and $2,028.2 million, respectively. The Consolidated Balance Sheets as of December 31, 2023 and 2022 include $1,550.0 million and $1,535.0 million, respectively, of senior undivided interests in accounts receivable balances sold to third parties, as well as borrowings for equal amounts. At December 31, 2023, the interest rate for this facility was approximately 6.23%. Under the Receivables Facility, Wesco Distribution sells, on a continuous basis, an undivided interest in all domestic accounts receivable to Wesco Receivables, a wholly-owned special purpose entity (the “SPE”). The SPE sells, without recourse, asenior undivided interest in the receivables to financial institutions for cash while maintaining a subordinated undivided interest in the receivables, in the form of overcollateralization. Since Wesco maintains control of the transferred receivables, the transfers do not qualify for “sale” treatment. As a result, the transferred receivables remain on the Company's balance sheet, and Wesco recognizes the related secured borrowing. Wesco has agreed to continue servicing the receivables for the third-party conduits and financial institutions at market rates; accordingly, no servicing asset or liability has been recorded. On October 31, 2022, Wesco Distribution amended its Receivables Facility pursuant to the terms and conditions of a Sixth Amendment to Fifth Amended and Restated Receivables Purchase Agreement (the “Sixth Receivables Amendment”). The Sixth Receivables Amendment amended the Receivables Purchase Agreement to increase its purchase limit from $1,525 million to $1,625 million.

On August 2, 2022, Wesco Distribution amended its Receivables Facility pursuant to the terms and conditions of a Fifth Amendment to Fifth Amended and Restated Receivables Purchase Agreement (the “Fifth Receivables Amendment”). The Fifth Receivables Amendment amended the Receivables Purchase Agreement to, among other things, increase the purchase limit under the Receivables Facility from $1,400 million to $1,525 million and to decrease the interest rate spread from 1.10% to 1.05%. The maturity date and commitment fee of the Receivables Facility remained unchanged. On March 1, 2022, Wesco Distribution amended its Receivables Facility pursuant to the terms and conditions of a Fourth Amendment to Fifth Amended and Restated Receivables Purchase Agreement (the “Fourth Receivables Amendment”). The Fourth Receivables Amendment, among other things, (i) increased the purchase limit under the Receivables Facility from $1,300 million to $1,400 million, (ii) increased the aggregate commitment under the accordion feature from $1,500 million to $1,750 million, and (iii) extended the maturity date from June 21, 2024 to March 1, 2025. Additionally, the Fourth Receivables Amendment replaced the LIBOR interest rate option with Secured Overnight Financing Rate-based (“SOFR”) interest rate options, including term SOFR and daily simple SOFR, and decreased the interest rate spread from 1.15% to 1.10%. The commitment fee of the Receivables Facility remained unchanged. On June 1, 2021, Wesco Distribution amended its Receivables Facility pursuant to the terms and conditions of a Third Amendment to the Fifth Amended and Restated Receivables Purchase Agreement (the “Third Receivables Amendment”).

The commitment fee of the Receivables Facility remained unchanged. On December 14, 2020, Wesco Distribution amended its Receivables Facility pursuant to the terms and conditions of a First Amendment to the Fifth Amended and Restated Receivables Purchase Agreement (the “First Receivables Amendment”). The First Receivables Amendment amended the Receivables Purchase Agreement and permitted an increase to the purchase limit from $1,025 million to $1,200 million. The maturity date, interest rate spread, and commitment fee of the Receivables Facility remained unchanged. The Receivables Purchase Agreement, among other things, increased the purchase limit under the Prior Receivables Purchase Agreement from $600 million to $1,025 million, with the opportunity to exercise an accordion feature that permits increases in the purchase limit up to an aggregate commitment of $1,400 million, subject to customary conditions, extended the maturity date to June 22, 2023 and added and amended certain defined terms. Borrowings under the Receivables Facility bear interest at the 30-day LIBOR rate, with a LIBOR floor, plus applicable spreads. The interest rate spread under the Receivables Purchase Agreement of 1.20% increased from 0.95% under the Prior Receivables Purchase Agreement. The Receivables Facility has a commitment fee of 0.45%. 65 WESCO INTERNATIONAL, INC.

The Revolving Credit Facility has a maturity date of March 1, 2027 and permits the Company to declare and pay an aggregate amount of common stock dividends of up to $80 million per year. The applicable interest rate for borrowings under the Revolving Credit Facility, as amended, includes interest rate spreads based on available borrowing capacity that range from 1.00% to 1.50% for SOFR-based borrowings and from 0.00% to 0.50% for prime rate-based borrowings. At December 31, 2023, the interest rate for this facility was approximately 6.89%.

The Notes Indenture contains certain covenants that, among other things, limit (i) the Company’s and its subsidiaries’ ability to pay dividends on or repurchase the Company’s capital stock, incur liens on assets, engage in certain sale and leaseback transactions or sell certain assets, and (ii) the Company’s and any guarantor’s ability to sell all or substantially all of its assets to, or merge or consolidate with or into, other persons, in the case of each of the foregoing, subject to certain qualifications and exceptions, including the termination of certain of these covenants upon the Notes receiving investment grade credit ratings. The Notes Indenture contains certain events of default, including, among other things, failure to make required payments, failure to comply with certain agreements or covenants, failure to pay or acceleration of certain other indebtedness, certain events of bankruptcy and insolvency, and failure to pay certain judgments. An event of default under the Notes Indenture will allow either the Trustee or the holders of at least 25% in aggregate principal amount of the applicable series of the then-outstanding Notes to accelerate, or in certain cases, will automatically cause the acceleration of the amounts due under the applicable series of Notes. Debt Issuance Costs Wesco capitalizes certain costs associated with the issuance of debt and such costs are amortized over the term of the respective debt instrument on a straight-line basis. Debt issuance costs are presented in the Consolidated Balance Sheets as a direct reduction to the carrying amount of the related debt liability. Upon prepayment of debt, the Company accelerates the recognition of an appropriate amount of the costs as refinancing or extinguishment of debt. As of December 31, 2023 and 2022, unamortized debt issuance costs of $37.4 million and $51.1 million were recorded in the Consolidated Balance Sheets, respectively. Covenant Compliance Wesco’s credit agreements contain various restrictive covenants that, among other things, impose limitations on: (i) dividend payments or certain other restricted payments or investments; (ii) the incurrence of additional indebtedness and guarantees; (iii) creation of liens; (iv) mergers, consolidation or sales of substantially all of Wesco’s assets; (v) certain transactions among affiliates; (vi) payments by certain subsidiaries to Wesco, and (vii) capital expenditures. In addition, the Revolving Credit Facility and the Receivables Facility require Wesco to meet certain fixed charge coverage tests depending on availability or liquidity, respectively. Wesco was in compliance with all financial covenants contained in its debt agreements as of December 31, 2023. 69 WESCO INTERNATIONAL, INC.

STOCKHOLDERS' EQUITY Preferred Stock There are 20 million shares of preferred stock authorized at a par value of $0.01 per share; there are no shares issued or outstanding. The Company's Board of Directors has the authority, without further action by the stockholders, to issue all authorized preferred shares in one or more series and to fix the number of shares, designations, voting powers, preferences, optional and other special rights and the restrictions or qualifications thereof. The rights, preferences, privileges and powers of each series of preferred stock may differ with respect to dividend rates, liquidation values, voting rights, conversion rights, redemption provisions and other matters. Series A Preferred Stock The Company's Board of Directors authorized 25,000 shares of fixed-rate reset cumulative perpetual preferred stock, Series A, with a liquidation preference of $25,000 per whole preferred share and apa r value of $0.01 per share (the “Series A Preferred Stock”). Depositary shares, each representing a 1/1,000th interest in a share of Series A Preferred Stock, are registered under the Securities Act. In connection with the Company’s merger with Anixter, the Company issued 21,611,534 depositary shares, representing an interest in approximately 21,612 shares of Series A Preferred Stock. Holders of shares of the Series A Preferred Stock are entitled to receive, when, as and if declared by the Company's Board of Directors, cumulative cash dividends at an initial rate of 10.625% per annum of the $25,000 liquidation preference per share. On June 22, 2025, and every five-year period thereafter, the dividend rate on the Series A Preferred Stock resets and will be equal to the Five-year U.S. Treasury Rate plus a spread of 10.325%. Holders of the Series A Preferred Stock are not entitled to convert or exchange their shares of Series A Preferred stock into shares of any of Wesco’s other classes or series of stock or into any other security of Wesco (other than upon a change of control involving the issuance of additional shares of common stock or other change of control transaction, in each case, approved by holders of common stock). The Series A Preferred Stock has no stated maturity and will not be subject to any sinking fund, retirement fund or purchase fund or any other obligation of Wesco to redeem, repurchase or retire the Series A Preferred Stock. On June 22, 2025, Wesco may redeem the Series A Preferred Stock, in whole or in part, for cash at a redemption price of $25,000 per share, plus all accrued and unpaid dividends. Holders of the Series A Preferred Stock will have limited voting rights, including the right to elect two directors to the Board of Directors of the Company in the event dividends on the Series A Preferred Stock remain unpaid for the equivalent of six or more full quarterly dividend periods. 70 WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) Common Stock There are 210 million shares of common stock and 20 million shares of Class B common stock authorized at a par value of $0.01 per share. The Class B common stock is identical to the common stock, except for voting and conversion rights. The holders of Class B common stock have no voting rights. With certain exceptions, Class B common stock may be converted, at the option of the holder, into the same number of shares of common stock. The terms of the Revolving Credit Facility, as well as the indentures governing the 2025 Notes and 2028 Notes, place certain limits on the Company's ability to declare or pay dividends and repurchase common stock. These restrictions are based on availability, as defined in the respective credit agreements, as well as Wesco's compliance with certain fixed charge coverage tests. At December 31, 2023 and 2022, no dividends had been declared that remained unpaid and, therefore, no retained earnings were reserved for dividend payments. Treasury Stock Common stock purchased for treasury is recorded at cost. At the date of subsequent reissue, the treasury stock account is reduced by the cost of such stock, with cost determined on a weighted-average basis. Share Repurchases On May 31, 2022, the Company's Board of Directors adopted a resolution authorizing the repurchase of up to $1 billion of the Company's common stock and Series A Preferred Stock. The share repurchase authorization has no expiration date and may be modified, suspended, or terminated at any time without prior notice. During the years ended December 31, 2023 and 2022, the Company entered into spot repurchase transactions through a broker to purchase 504,335 and 87,502 shares, respectively, of its common stock in the open market for cash totaling $75.0 million and $11.1 million, respectively. Wesco funded the repurchases with available cash and borrowings under its revolving credit facility and the repurchases were made within the limits described above. Dividends The Company's dividends on common stock are declared at the discretion of the Board of Directors. During the fiscal year ended December 31, 2023, the Board of Directors declared and the Company paid quarterly cash dividends totaling $76.6 million to common stockholders.

The CAMT imposes a minimum tax of 15% on the adjusted financial statement income (“AFSI”) of certain corporations with average annual AFSI over a three-year period in excess of $1 billion, so-called “applicable corporations”. CAMT is effective for tax years beginning after December 31, 2022. The Company was not subject to CAMT in 2023 and does not expect to be subject to it in 2024. The undistributed earnings of the Company's foreign subsidiaries amounted to approximately $2,194.1 million as of December 31, 2023. Most of these earnings have been taxed in the U.S. under either the one-time transition tax or the GILTI tax regime imposed by the TCJA. Wesco has elected to pay the transition tax in installments over an eight year period ending in 2026. As of December 31, 2023, the Company's remaining liability for the transition tax was $53.8 million, which is recorded as components of other current and noncurrent liabilities in the Consolidated Balance Sheet. The Company continues to assert that the remaining undistributed earnings of its foreign subsidiaries are indefinitely reinvested. The distribution of earnings by Wesco's foreign subsidiaries in the form of dividends, or otherwise, may be subject to additional taxation. The Company estimates that additional taxes of approximately $119.3 million would be payable upon the remittance of all previously undistributed foreign earnings as of December 31, 2023, based upon the laws in effect on that date. The Company believes that it is able to maintain sufficient liquidity for its domestic operations and commitments without repatriating cash from Wesco's foreign subsidiaries. 72 WESCO INTERNATIONAL, INC.

These net operating loss carryforwards expire beginning in 2026 through 2043, while some may be carried forward indefinitely. The Company has determined that certain foreign net operating loss carryforwards will not be realized before they expire. Accordingly, the Company has recorded a valuation allowance of $12.9 million and $16.7 million against deferred tax assets related to certain foreign net operating loss carryforwards as of December 31, 2023 and 2022, respectively. Additionally, these foreign jurisdictions had deferred tax assets of $6.1 million and $10.9 million as of December 31, 2023 and 2022, respectively, related to other future deductible temporary differences. The Company has recorded a full valuation allowance against these amounts as of December 31, 2023 and 2022, respectively. As of December 31, 2023 and 2022, Wesco had deferred tax assets of $3.0 million and $4.4 million, respectively, related to state net operating loss carryforwards. These net operating loss carryforwards expire beginning in 2024 through 2041, while some may be carried forward indefinitely. The Company has determined that certain state net operating loss carryforwards will not be realized. Accordingly, the Company has recorded a valuation allowance of $1.0 million against deferred tax assets related to certain state net operating loss carryforwards as of December 31, 2023. As of December 31, 2023 and 2022, Wesco had deferred tax assets of $1.9 million and $4.8 million, respectively, related to disallowed business interest expense for state income tax purposes. The carryforward period for disallowed business interest expense is indefinite. The Company has determined that certain state disallowed business interest expense carryforwards will not be realized. Accordingly, the Company has recorded a valuation allowance of $0.5 million against deferred tax assets related to certain state disallowed business interest expense carryforwards as of December 31, 2023. As of December 31, 2023 and 2022, Wesco had deferred tax assets of $41.1 million and $52.2 million, respectively, related to foreign tax credit carryforwards. The foreign tax credit carryforwards expire beginning in 2027 through 2033. The Company has determined that certain foreign tax credit carryforwards will not be realized before they expire. Accordingly, the Company has recorded a valuation allowance of $2.9 million and $6.1 million against these deferred tax assets as of December 31, 2023 and 2022, respectively. Wesco’s ability to realize its deferred tax assets related to foreign tax credit carryforwards may be impacted by U.S. tax legislation, our ability to generate sufficient foreign source taxable income, and tax planning strategies that the Company may implement. The impact of these items, if any, on Wesco's assessment of the realizability of these deferred tax assets will be recorded as a discrete item in the period in which the Company's assessment changes. 73 WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) The Company is under examination by tax authorities in various jurisdictions and remains subject to examination until the applicable statutes of limitation expire. The statutes of limitation for the material jurisdictions in which the Company files income tax returns remain open as follows: United States —Fe deral United States — Material States Canada UK Australia 2020 and forward 2017 and forward 2012 and forward 2018 and forward 2018 and forward The following table sets forth the reconciliation of gross unrecognized tax benefits: Beginning balance January 1 Additions for current year tax positions Additions for prior year tax positions Additions for acquired tax positions Reductions for prior year tax positions Settlements Lapse in statute of limitations Foreign currency exchange rate changes Ending balance December 31 2023 As of December 31, 2022 (In millions) 2021 109.3 29.2 6.6 0.9 (6.7) (2.5) (15.8) 0.3 121.3 $ $ 107.3 14.4 0.9 5.5 (1.8) — (14.5) (2.6) 109.3 $ $ 68.1 39.8 8.4 — (3.9) (0.1) (3.8) (1.2) 107.3 $ $ The amount of unrecognized tax benefits that would affect the effective tax rate if recognized in the consolidated financial statements for the years ended December 31, 2023, 2022 and 2021 were $40.1 million, $40.6 million, and $36.1 million, respectively. Within the next twelve months, the amount of unrecognized tax benefits is expected to decrease by $16.5 million due to the expiration of statutes of limitation. Such change would result in a$7 .6 million reduction in income tax expense. The Company classifies interest related to unrecognized tax benefits as a component of interest expense, net in the Consolidated Statements of Income and Comprehensive Income. The Company recognized interest income on unrecognized tax benefits of $1.1 million for the year ended December 31, 2023. The Company recognized interest expense on unrecognized tax benefits of $2.3 million and $0.9 million for the years ended December 31, 2022 and 2021, respectively. As of December 31, 2023 and 2022, Wesco had a liability of $8.9 million and $9.6 million, respectively, for interest expense related to unrecognized tax benefits. The Company classifies penalties related to unrecognized tax benefits as part of income tax expense. Penalties recorded in income tax expense for the years ended December 31, 2023 , 2022 and 2021 were immaterial. As of December 31, 2023 and 2022, Wesco had a liability of $4.7 million and $4.8 million, respectively, for penalties related to unrecognized tax benefits. On October 22, 2021, one of the Company's Mexican affiliates received ata x assessment from the Mexican tax authorities in the amount of approximately $26.0 million related to its 2012 income tax return. This amount, updated for adjustments required under Mexican law, was approximately $33.0 million as of December 31, 2023. The Company believes the assessment is without merit and has filed an annulment lawsuit in the Mexican Federal Court of Administrative Justice. The Company expects to prevail in this litigation and, accordingly, has not recognized a liability for this assessment in its consolidated financial statements. 74 WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) In July 2022, one of the Company's Canadian affiliates received tax assessments from the Canada Revenue Agency (“CRA”) totaling approximately $11.0 million, including tax and interest, related to its 2012 through 2014 income tax returns. The Company's Canadian affiliate received a related penalty assessment of approximately $2.7 million in May 2023. The Company believes these assessments are without merit and has appealed to the Tax Court of Canada. The Company intends to avail itself of all avenues to appeal, as necessary to overturn the assessments and expects to prevail. Therefore, the Company has not recognized a liability for these assessments in its consolidated financial statements. The CRA continues to audit the 2015 and 2016 tax years of Wesco's Canadian affiliates and has made inquiries into their 2017 through 2019 income tax returns. The Company expects to eventually receive similar assessments for these tax years. 75 WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) 12. EARNINGS PER SHARE Basic earnings per share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding during the periods. Diluted earnings per share is computed by dividing net income attributable to common stockholders by the weighted-average common shares and common share equivalents outstanding during the periods. The dilutive effect of common share equivalents is considered in the diluted earnings per share computation using the treasury stock method, which includes consideration of equity awards. The following table sets forth the details of basic and diluted earnings per share: (In millions, except per share data) Net income attributable to WESCO International, Inc.

For the years ended December 31, 2023 and 2022, there were approximately 0.2 million and 0.1 million antidilutive stock-based awards, respectively. For the year ended December 31, 2021, there were no antidilutive stock-based awards. 13. EMPLOYEE BENEFIT PLANS Defined Contribution Plans Wesco Distribution sponsors a defined contribution retirement savings plan for the majority of its U.S. employees (the “WESCO Distribution, Inc. Retirement Savings Plan”), which provides employer matching contributions. Contributions are made in cash and employees have the option to transfer balances allocated to their accounts into any of the available investment options. Prior to January 1, 2022, the Company could also make, subject to the Board of Directors' approval, a discretionary contribution to the WESCO Distribution, Inc. Retirement Savings Plan if certain predetermined profit levels were attained. The amendments to the WESCO Distribution, Inc. Retirement Savings described below eliminated the discretionary employer contributions. Discretionary employer contribution charges of $13.1 million were incurred for the year ended December 31, 2021. Anixter Inc. sponsored a defined contribution plan that covered all of its non-union U.S. employees (the “Anixter Inc. Employee Savings Plan”). The employer match for the Anixter Inc. Employee Savings Plan was equal to 50% of a participant's contribution up to 5% of the participant's compensation. Anixter Inc. also made an annual contribution to the Anixter Inc. Employee Savings Plan on behalf of each active participant who was hired or rehired on or after July 1, 2015, or was not participating in the Anixter Inc. Pension Plan. The amount of the employer annual contribution was equal to either 2% or 2.5% of the participant’s compensation, as determined by the participant’s years of service. This contribution was in lieu of being eligible for the Anixter Inc. Pension Plan. Certain of Anixter Inc.'s foreign subsidiaries also have defined contribution plans. Contributions to these plans are based upon various levels of employee participation and legal requirements. 76 WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) Effective January 1, 2022, the Anixter Inc. Employee Savings Plan was merged with and into the WESCO Distribution, Inc. Retirement Savings Plan (the “U.S. Defined Contribution Plan Merger”). On December 31, 2021, participant account balances were transferred from the Anixter Inc. Employee Savings Plan to the WESCO Distribution, Inc. Retirement Savings Plan. In connection with the U.S. Defined Contribution Plan Merger, the WESCO Distribution, Inc. Retirement Savings plan was amended to change the employer matching contribution from an amount equal to 50% of participants' total monthly contributions up to 6% of eligible compensation to an amount equal to 100% of a participant’s eligible elective deferrals up to 3% of the participant’s eligible compensation and 50% of the next 4% of eligible compensation, and to eliminate the discretionary employer contributions. WESCO Distribution Canada LP, a wholly-owned subsidiary of the Company, sponsors ade fined contribution plan covering the current full-time employees of WESCO Distribution Canada LP and part-time employees meeting certain requirements for continuous service, earnings and minimum hours of employment (the “Wesco Canadian Defined Contribution Plan”).

For employees having completed between 20 and 25 or more years of service as of January 1, 2015, the Company's contribution ranged from 5% to 7% of the respective participants' eligible compensation. Anixter Canada Inc. sponsored a defined contribution plan for certain employees of Anixter Canada Inc. and Anixter Power Solutions Canada Inc. (the “Anixter Canadian Defined Contribution Plan”), which provided for core employer contributions in amounts ranging from 3% to 4% of participants' eligible compensation based on years of continuous service, plus a matching contribution equal to 25% of a participant’s elective contributions up to 6% of eligible compensation (for a maximum total employer contribution equal to 5.5%). Effective January 1, 2022, the Anixter Canadian Defined Contribution Plan was merged with and into an amended Wesco Canadian Defined Contribution Plan. During the first quarter of 2022, participant account balances were transferred from the Anixter Canadian Defined Contribution Plan to the amended Wesco Canadian Defined Contribution Plan. The amended Wesco Canadian Defined Contribution Plan provides acore employer contribution of 3% of a participant’s eligible compensation, plus a matching contribution equal to 50% of apa rticipant’s elective contributions up to 4% of eligible compensation (for a maximum total employer contribution equal to 5%). The amended Wesco Canadian Defined Contribution Plan also requires employees of EECOL Electric Corp. hired on or after January 1, 2022 to join this defined contribution plan, and permits enrollment for those not participating in the defined benefit plan described below. Wesco incurred charges of $73.4 million, $58.2 million, and $54.7 million for the years ended December 31, 2023, 2022 and 2021, respectively, for all defined contribution plans. Deferred Compensation Plans Wesco Distribution sponsors a non-qualified deferred compensation plan (the “Wesco Deferred Compensation Plan”) that permits select employees to make pre-tax deferrals of salary and bonus. Employees have the option to transfer balances allocated to their accounts in the Wesco Deferred Compensation Plan into any of the available investment options. The Wesco Deferred Compensation Plan is an unfunded plan. As of December 31, 2023 and 2022, the Company's obligation under the Wesco Deferred Compensation Plan was $27.4 million and $20.3 million, respectively, which is included in other noncurrent liabilities in the Consolidated Balance Sheet. Anixter Inc. sponsored a non-qualified deferred compensation plan (the “Anixter Deferred Compensation Plan”) that permitted select employees to make pre-tax deferrals of salary and bonus. Interest was accrued monthly on the deferred compensation balances based on the average ten-year Treasury note rate for the previous three months times a factor of 1.4, and the rate was further adjusted if certain financial goals were achieved. In the fourth quarter of 2020, the Company terminated the Anixter Deferred Compensation Plan and settled it in the second quarter of 2021 by making lump sum payments of $42.8 million directly to participants. The Company used the proceeds from liquidating certain assets held in a Rabbi Trust arrangement of approximately $39.7 million, plus available cash, to fund the settlement of the Anixter Deferred Compensation Plan. 77 WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) Defined Benefit Plans Wesco sponsors aco ntributory defined benefit plan covering substantially all Canadian employees of EECOL Electric Corp., a wholly-owned subsidiary of the Company (the “EECOL Plan”). The EECOL Plan provides retirement benefits based on earnings and credited service, and participants contribute 2% of their earnings to the EECOL Plan. Participants become 100% vested after two years of continuous service or, if earlier, at the participant's normal retirement age. Wesco also sponsors aSu pplemental Executive Retirement Plan for certain executives of EECOL Electric Corp. (the “EECOL SERP”), which provides additional pension benefits based on earnings and credited service.

Participants of the EECOL SERP now contribute 4% of their earnings to the EECOL Plan. Anixter Inc. sponsors the Anixter Inc. Pension Plan, which was closed to entrants first hired or rehired on or after July 1, 2015, and various defined benefit pension plans covering employees of foreign subsidiaries in Canada and Europe (together with the EECOL Plan and the EECOL SERP, the “Foreign Plans”). The majority of the Company's defined benefit pension plans are non- contributory, and with the exception of the U.S. and Canada, cover substantially all full-time employees in their respective countries. Retirement benefits are provided based on compensation as defined in each of the plan agreements. The Anixter Inc. Pension Plan is funded as required by the Employee Retirement Income Security Act of 1974 (“ERISA”) and the Internal Revenue Service. With the exception of the EECOL SERP, which is an unfunded plan, the Foreign Plans are funded as required by applicable foreign laws. Anixter Inc. also sponsored the Anixter Inc. Executive Benefit Plan and the Supplemental Executive Retirement Plan (the “Anixter SERP”) (together with the Anixter Inc. Pension Plan, the “Domestic Plans”). In the fourth quarter of 2020, the Company terminated both the Anixter Inc. Executive Benefit Plan and the Anixter SERP. During the year ended December 31, 2021, the Company settled its liabilities for these plans by making lump sum payments directly to participants totaling $17.9 million. During the fourth quarter of 2021, the Company adopted certain plan amendments to: (i) freeze the benefits provided under the Anixter Inc. Pension Plan effective December 31, 2021, (ii) close participation in the EECOL Plan effective December 31, 2021, and (iii) freeze the benefit accruals under the Pension Plan for Employees of Anixter Canada Inc., the EECOL Plan and the EECOL SERP effective December 31, 2023. These amendments required the Company to remeasure the projected benefit obligations associated with these plans, resulting in aga in from curtailment recognized during the fourth quarter of 2021. During the fourth quarter of 2022, the Company terminated the Anixter Inc. Pension Plan effective December 31, 2022. Accordingly, certain estimates that reflect the pending settlement of this plan were incorporated into the assumptions used to measure the respective projected benefit obligation as of December 31, 2023 and 2022. As the Anixter Inc. Pension Plan had previously been frozen, its termination did not result in any curtailment gain or loss for the years ended December 31, 2023 or 2022. The benefit obligation associated with this plan was partially settled during the fourth quarter of 2023 by making lump sum cash payments to participants totaling $110.9 million and the Company recognized settlement cost of $4.7 million. On February 12, 2024, the remaining benefit obligation of the Anixter Inc. Pension Plan was settled through the purchase of single premium annuity contracts for total cash of $138.8 million. The purchase was funded entirely by the assets of the plan. The final remeasurement of the plan will occur in the first quarter of 2024. Unrealized gains or losses currently reported as components of other comprehensive income (loss) related to the benefit obligation of the Anixter Inc. Pension Plan will be recognized in a final settlement charge at that time. 78 WESCO INTERNATIONAL, INC.

Accordingly, at the end of each fiscal year, the Company determines the discount rate to measure the plan liabilities at their present value. The discount rate reflects the current rate at which the pension liabilities could effectively be settled at the measurement date. This rate was estimated at the end of 2023 and 2022 using a yield curve based on corporate bond data, which the Company concluded was consistent with observable market conditions and industry standards for developing spot rate curves. The Company had nine plans at December 31, 2023 and seven plans at December 31, 2022 for which the projected benefit obligation was in excess of the fair value of plan assets. For these plans, the aggregate projected benefit obligation was $215.0 million and $119.0 million, respectively, and the aggregate fair value of plan assets was $183.8 million and $91.0 million, respectively. 79 WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) At December 31, 2023 and 2022, the Company's accumulated benefit obligation was $147.5 million and $253.5 million, respectively, for the Domestic Plans and $302.5 million and $253.2 million, respectively, for the Foreign Plans. The Company had nine plans at December 31, 2023 and seven plans at December 31, 2022 for which the accumulated benefit obligation was in excess of the fair value of plan assets. For these plans, the aggregate accumulated benefit obligation was $208.6 million and $113.7 million, respectively, and the aggregate fair value of plan assets was $183.8 million and $91.0 million, respectively.

The other components of net periodic pension cost (benefit) totaling net cost of $0.2 million for the year ended December 31, 2023 and net benefits of $14.8 million and $53.2 million for the years ended December 31, 2022 and 2021, respectively, are presented as components of other non- operating expense (income) (“other expense (income), net”). The following weighted-average actuarial assumptions were used to determine net periodic pension cost (benefit): Domestic Plans Foreign Plans 2023 2022 2021 2023 2022 2021 2023 Discount rate Expected return on plan assets Rate of compensation increase 4.4 % 4.8 % — % 2.9 % 4.3 % — % 2.6 % 5.3 % 3.8 % 4.8 % 5.5 % 3.4 % 2.4 % 5.0 % 3.4 % 2.0 % 4.9 % 3.2 % 4.6 % 5.1 % 3.4 % Total 2022 2.6 % 4.6 % 3.4 % 2021 2.3 % 5.1 % 3.4 % The expected long-term rate of return on plan assets reflects the average rate of earnings expected on the invested assets and future assets to be invested to provide for the benefits included in the projected benefit obligation. The Company uses historical plan asset returns combined with current market conditions to estimate the rate of return. As a result of the combined effect of valuation changes in both the equity and bond markets, the plan assets produced an actual gain of 7.0% in 2023. The difference between the expected return and actual return on plan assets is amortized into expense over the service lives of the plan participants. These amounts are reflected on the balance sheet through charges to accumulated other comprehensive (income) loss. 80 WESCO INTERNATIONAL, INC.

The Company does not expect to make a contribution to its domestic qualified pension plan in 2024 due to its overfunded status and anticipated settlement in the first quarter of 2024, as described above. The assets of the various defined benefit plans are held in separate independent trusts and managed by independent third party advisors. The investment objective for the defined benefit plans is to ensure an adequate level of assets is available to fund the benefits owed to employees and their beneficiaries when they become payable. In meeting this objective, the Company seeks to achieve a level of absolute investment return consistent with a prudent level of portfolio risk. The Company's risk preference is to refrain from exposing the plans to higher volatility in pursuit of potential higher returns. 81 WESCO INTERNATIONAL, INC.

For 2023, the investment policy guidelines of the Domestic Plans were as follows: Each asset class is managed by one or more active and passive investment managers Each asset class may be invested in a commingled fund, mutual fund, or separately managed account • • • • • Derivative instruments such as futures, swaps and options may be used on alimited basis; for funds that employ Each manager is expected to be “fully invested” with minimal cash holdings Investment in Exchange Traded Funds is permissible • • derivatives, the loss of invested capital to the trust should be limited to the amount invested in the fund The equity portfolio is diversified by sector and geography The fixed income is invested in U.S. Treasuries, investment grade corporate debt (denominated in U.S. dollars), and other credit investments including below investment grade rated bonds and loans, securitized credit, and emerging market debt The investment policies for the Foreign Plans are the responsibility of the various trustees. Generally, the investment policy guidelines are as follows: • Make sure that the obligations to the beneficiaries of the plan can be met • Maintain funds at a level to meet the minimum funding requirements • The investment managers are expected to provide a return, within certain tracking tolerances, close to that of the relevant market’s indices 83 WESCO INTERNATIONAL, INC.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) The assets of the Domestic Plans and Foreign Plans are measured at fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Financial assets and liabilities are classified in the fair value hierarchy based on the lowest level of any input that is significant to the measurement of fair value. Investments for which fair value is measured using the net asset value per share practical expedient are not classified in the fair value hierarchy. The majority of pension assets are comprised of common/collective/pool funds (i.e., mutual funds). These funds are valued at the net asset value of shares held in the underlying funds. The fair value methods described above may not be indicative of net realizable value or reflective of future fair values. Additionally, while the Company believes the valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. Other Benefits Prior to its acquisition by Wesco on June 22, 2020, Anixter granted restricted stock units in the ordinary course of business to its employees and directors. These awards, for which vesting did not accelerate solely as a result of the Company's merger with Anixter, were converted into cash-only settled Wesco phantom stock units, which vested ratably over a 3-year period. As of December 31, 2023, these awards had fully vested and have no remaining fair value or liability. As of December 31, 2022, the estimated fair value of these awards was $8.1 million and the Company's liability for these awards was $8.0 million, which is included in accrued payroll and benefit costs in the Consolidated Balance Sheet. The Company recognized compensation expense associated with these awards of $0.1 million, $2.6 million, and $13.6 million for the years ended December 31, 2023, 2022, and 2021, respectively, which is reported as aco mponent of selling, general and administrative expenses. 14. STOCK-BASED COMPENSATION Wesco sponsors ast ock-based compensation plan. On May 27, 2021, the Company's stockholders approved the WESCO International, Inc. 2021 Omnibus Incentive Plan (the “2021 Plan”). The 2021 Plan is administered by the Compensation Committee of the Company's Board of Directors. The 2021 Plan was designed to be the successor plan to all prior stock-based compensation plans. Accordingly, no new awards may be granted under the Company’s 1999 Long-Term Incentive Plan, as amended and restated (the “1999 Plan”) or any other prior plan. Awards outstanding under any such prior plans will remain in full force and effect under such plans according to their respective terms. To the extent that any such award is forfeited, terminates, expires or lapses without being exercised, or is settled for cash, the shares subject to such award not delivered will again be available for awards under the 2021 Plan. The maximum number of shares of the Company’s common stock that may be granted pursuant to awards under the 2021 Plan is 2,150,000, less any shares issued under the 1999 Plan between March 31, 2021 and May 27, 2021. If any award granted under the 2021 Plan is forfeited, terminates, expires or lapses instead of being exercised, or is settled for cash, the shares subject to such award will again be available for grant under the 2021 Plan. Shares delivered by participants or withheld by the Company to pay all or a portion of the exercise price or withholding taxes with respect to stock option or stock appreciation right awards will not again be available for issuance. Shares delivered by participants or withheld by the Company to satisfy applicable tax withholding obligations with respect to restricted shares or restricted stock units will again be available for grant under the 2021 Plan. As of December 31, 2023, 1,877,701 shares of common stock were reserved under the 2021 Plan for future equity award grants. Stock-based compensation awards outstanding under Wesco's plans comprise stock options, stock-settled stock appreciation rights, restricted stock units and performance-based awards. Compensation cost for all stock-based awards is measured at fair value on the date of grant and compensation cost is recognized, net of estimated forfeitures, over the service period for awards expected to vest. The fair value of stock options and stock-settled stock appreciation rights is determined using the Black-Scholes model. The fair value of restricted stock units and performance-based awards with performance conditions is determined by the grant-date closing price of Wesco’s common stock. The forfeiture assumption is based on Wesco’s historical participant behavior 86 WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) that is reviewed on at least an annual basis. For stock options and stock-settled stock appreciation rights that are exercised, and for restricted stock units and performance-based awards that vest, shares are issued out of Wesco's outstanding common stock. Stock options and stock-settled stock appreciation rights vest ratably over a three-year period and terminate on the tenth anniversary of the grant date unless terminated sooner under certain conditions. Restricted stock unit awards that were granted under the 1999 Plan vest fully on the third anniversary of the date of grant, except for the special award described below, which vested in tranches. Restricted stock units awarded under the 2021 Plan vest ratably over a three-year period on each of the first, second and third anniversaries of the grant date. Vesting of performance-based awards is based on a three-year performance period, and the number of shares earned, if any, depends on the attainment of certain performance levels, as described below. Outstanding awards would vest upon the consummation of a change in control transaction with performance-based awards vesting at the target level. On July 2, 2020, a special award of restricted stock units was granted to certain officers of the Company. These awards vested in tranches of 30% on each of the first and second anniversaries of the grant date and 40% on the third anniversary of the grant date, subject to continued employment through the applicable anniversary date. Performance-based awards are based on two equally-weighted performance measures: the three-year average growth rate of Wesco's net income attributable to common stockholders and the three-year cumulative return on net assets. These awards are accounted for as awards with performance conditions; compensation cost is recognized over the performance period based upon Wesco's determination of whether it is probable that the performance targets will be achieved. Wesco recognized $48.1 million, $46.4 million and $30.8 million of non-cash stock-based compensation expense for the years ended December 31, 2023, 2022 and 2021, respectively, which is included in selling, general and administrative expenses for all such periods. As of December 31, 2023, there was $50.2 million of total unrecognized compensation expense related to non- vested stock-based compensation arrangements for all awards previously made, which is expected to be recognized as follows: For the year ending December 31, (In millions) 2024 2025 2026 $ 32.2 16.1 1.9 The aggregate intrinsic value of awards exercised during the years ended December 31, 2023, 2022, and 2021 was $172.8 million, $68.3 million, and $69.7 million, respectively. The gross income tax benefit associated with the exercise of stock-based awards totaled $40.8 million, $15.8 million, and $16.8 million in 2023, 2022, and 2021, respectively. During the years ended December 31, 2023, 2022 and 2021, Wesco granted the following stock options, stock-settled stock appreciation rights, restricted stock units, and performance-based awards at the following weighted-average fair values: Stock options granted Weighted-average fair value Stock-settled stock appreciation rights granted Weighted-average fair value Restricted stock units granted Weighted-average fair value Performance-based awards granted(1) Weighted-average fair value(1) $ $ $ 87 Year Ended December 31, 2022 92,799 57.15 2023 78,729 76.69 $ 2021 — n/a — n/a — 139,592 33.19 n/a $ 177,659 169.65 234,800 $ 122.13 212,656 87.04 83,991 $ 122.09 314,480 77.81 122,812 76.76 $ $ WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) (1) As described further below, the year ended December 31, 2023 includes performance-based awards granted in February 2020 for which actual achievement levels were certified in February 2023, as well as performance-based awards granted during the year ended December 31, 2023. The fair values of stock options and stock-settled stock appreciation rights, as disclosed in the table above, were estimated using the following weighted-average assumptions in the respective periods: Risk free interest rate Expected life (in years) Expected volatility Expected dividend yield Year Ended December 31, 2022 2.0% 7 43% n/a 2023 4.1% 5 50% 0.89% 2021 0.8% 7 41% n/a The risk-free interest rate is based on the U.S. Treasury Daily Yield Curve rate as of the grant date.

COMMITMENTS AND CONTINGENCIES From time to time, a number ofla wsuits and claims have been or may be asserted against the Company relating to the conduct of its business, including litigation relating to commercial, product and employment matters (including wage and hour). The outcome of any litigation cannot be predicted with certainty, and some lawsuits may be determined adversely to Wesco. However, management does not believe that the ultimate outcome of any such pending matters is likely to have a material adverse effect on Wesco's financial condition or liquidity, although the resolution in any fiscal period of one or more of these matters may have a material adverse effect on Wesco's results of operations for that period. As of December 31, 2023, the Company had $60.9 million in outstanding letters of credit and guarantees. 16. BUSINESS SEGMENTS The Company has operating segments comprising three strategic business units consisting of EES, CSS and UBS. These operating segments are equivalent to the Company's reportable segments. The Company's chief operating decision maker evaluates the performance of its operating segments based on net sales, adjusted earnings before interest, taxes, depreciation and amortization (“EBITDA”), and adjusted EBITDA margin percentage. 89 WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED) The Company incurs corporate costs primarily related to treasury, tax, information technology, legal and other centralized functions. The Company also has various corporate assets. Segment assets may not include jointly used assets, but segment results include depreciation expense or other allocations related to those assets. Interest expense and other non-operating items are either not allocated to the segments or reviewed on ase gment basis. Corporate expenses and assets not directly identifiable with a reportable segment are reported in the tables below to reconcile the reportable segments to the consolidated financial statements. The following is a description of each of the Company's reportable segments and their business activities. Electrical & Electronic Solutions The EES segment, with approximately 6,800 employees supporting customers in more than 50 countries, supplies a broad range of products and solutions primarily to the construction, industrial and original equipment manufacturer (“OEM”) markets. The product portfolio in this business includes a broad range of electrical equipment and supplies, automation and connected devices (the “Internet of Things” or “IoT”), security, lighting, wire and cable, safety, and maintenance, repair and operating (“MRO”) products from industry-leading manufacturing partners. The EES service portfolio includes contractor solutions to improve project execution, direct and indirect manufacturing supply chain optimization programs, lighting and renewables advisory services, and digital and automation solutions to improve safety and productivity. Communications & Security Solutions The CSS segment, with approximately 4,400 employees supporting customers in more than 50 countries, is a global leader in the network infrastructure and security markets. CSS sells products directly to end-users or through various channels including data communications contractors, security, network, professional audio/visual and systems integrators. In addition to the core network infrastructure and security portfolio, CSS has a broad offering of safety and energy management solutions. CSS products are often combined with supply chain services to increase efficiency and productivity, including installation enhancement, project deployment, advisory, and IoT and digital services. Utility & Broadband Solutions The UBS segment, with approximately 2,900 employees supporting customers primarily in the U.S. and Canada, provides products and services to investor-owned utilities, public power companies, including municipalities, as well as global service providers, wireless providers, broadband operators and the contractors that service these customers. The UBS segment also includes Wesco’s integrated supply business, which provides products and services to large industrial and commercial end-users to support their MRO spend. The products sold into the utility and broadband markets include wire and cable, transformers, transmission and distribution hardware, switches, protective devices, connectors, lighting, conduit, fiber and copper cable, connectivity products, pole line hardware, racks, cabinets, safety and MRO products, and point-to-point wireless devices. The UBS segment also offers a complete set of service solutions to improve customer supply chain efficiencies.

Controls and Procedures. Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of our disclosure controls and procedures (as defined in Exchange Act Rules 13a- 15(e) and 15d-15(e)). Based on this evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report. Management’s Report on Internal Control Over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). 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. Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the updated framework in Internal Control — Integrated Framework (2013) (2013 Framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission on May 14, 2013. Based on our evaluation under the 2013 Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2023. The effectiveness of the Company’s internal control over financial reporting as of December 31, 2023 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report, which is included herein. Changes in Internal Control Over Financial Reporting During the last fiscal quarter of 2023, there were no changes in the Company’s internal control over financial reporting identified in connection with management’s evaluation of the effectiveness of the Company’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
