ITEM 1. BUSINESS

General

We are a leading independent owner and operator of wireless communications infrastructure, including tower structures, rooftops, and other structures that support antennas used for wireless communications, which we collectively refer to as “towers” or “sites.” Our principal operations are in the United States and its territories. In addition, we own and operate towers in South America, Central America, Canada, South Africa, the Philippines, and Tanzania. Our primary business line is our site leasing business, which contributed 97.4% of our total segment operating profit for the year ended December 31, 2023. In our site leasing business, we (1) lease space to wireless service providers and other customers on assets that we own or operate and (2) manage rooftop and tower sites for property owners under various contractual arrangements. As of December 31, 2023, we owned 39,618 towers, a substantial portion of which have been built by us or built by other tower owners or operators who, like us, have built such towers to lease space to multiple wireless service providers. Our other business line is our site development business, through which we assist wireless service providers in developing and maintaining their own wireless service networks.

Business Strategy

Our primary strategy is to continue to focus on expanding our site leasing business through organic growth and expansion of our tower portfolio to create shareholder value. We believe that the long-term and repetitive nature of our site leasing business will permit us to maintain a stable, recurring cash flow stream and reduce our exposure to cyclical changes in customer spending which arises in our site development business. We believe that our tower operations are highly scalable. Consequently, we believe that we are able to materially increase our domestic and international tower portfolio without proportionately increasing selling, general, and administrative expenses. Key elements of our strategy include:

Organic Growth.

Maximizing our Tower Capacity. We generally have constructed or acquired towers that accommodate multiple tenants and a majority of our towers are high capacity tower structures. Most of our towers have significant capacity available for additional antennas, and we believe that increased use of our towers’ structural capacity can generate additional lease revenue and be achieved at a low incremental cost. We measure the available capacity of our existing sites to support additional tenants by assessing several factors, including tower height, tower type, wind loading, environmental conditions, existing equipment on the tower and zoning and permitting regulations in effect in the jurisdiction where the tower is located. We actively market space on our towers through our internal sales force. As of December 31, 2023, we had an average of 1.9 tenants per tower.

Capitalizing on our Scale and Management Experience. We are a large owner, operator and developer of towers, with substantial capital, human, and operating resources. We have been developing towers for wireless service providers in the U.S. since 1989 and owned and operated towers for ourselves since 1997. We believe our size, experience, capabilities, and resources make us a preferred partner for wireless service providers both in the U.S. and internationally. Our management team has extensive experience in site leasing and site development, with some of the longest tenures in the tower and site development industries. We believe that our industry expertise and strong relationships with wireless service providers will permit us to continue to organically grow our site leasing and site development services.

Systematic Tower Portfolio Growth. We intend to continue to grow our tower portfolio, domestically and internationally, through tower acquisitions and the construction of new tower structures. We believe that one of the best uses of our liquidity, including cash from operating activities and borrowings, is to acquire and/or build new towers at prices that we believe will be accretive to our shareholders both in the short and long term and which allow us to maintain our long-term target leverage ratios.

Disciplined Tower Acquisitions. In our tower acquisition program, we pursue towers from third parties that meet or exceed our internal guidelines regarding current and future potential returns. For each acquisition, we prepare various analyses that include projections of several different investment return metrics, review of available capacity, future lease up projections, and a summary of current and future tenant/technology mix.

New Build Program. We build new towers domestically and internationally. In our new build program, we construct tower structures (1) under build-to-suit arrangements or (2) in locations that are strategically chosen by us. Under build-to-suit arrangements, we build tower structures for wireless service providers at locations that they have identified. Under these arrangements, we retain ownership of the tower structure and the exclusive right to co-locate additional tenants. When we construct tower structures in locations chosen by us, we utilize our knowledge of our customers’ network requirements to identify locations where we believe multiple wireless service providers need, or will need, to locate antennas to meet capacity or service demands. We seek to identify attractive locations for new tower structures and complete pre-construction procedures necessary to secure the site concurrently with our leasing efforts. We generally will have at least

1

one signed tenant lease for each new build tower structure on the day that it is completed and expect that some will have multiple tenants.

International Tower Growth. The majority of our international markets typically have less mature wireless networks with limited wireline infrastructure and lower wireless data penetration rates than those in the United States. Accordingly, our tower growth in these markets is primarily driven by (1) wireless service providers seeking to increase the quality and coverage of their networks, (2) increased consumer mobile data traffic, such as media streaming, mobile apps and games, web browsing, and email, and (3) incremental spectrum auctions as well as incremental voice and data network deployments.

Opportunistic International Market Expansion. We believe that we can create substantial value by expanding our site leasing services into select international markets which we believe have an attractive wireless industry and relatively stable political and regulatory environments. We continually evaluate various factors when identifying potential markets for new expansion or continued involvement (as noted by our exit of the Argentinian market in the fourth quarter of 2023), including:

o Country analysis – We consider the country’s economic and political stability and whether the country’s general business, legal, and regulatory environment is conducive to the sustainability and growth of our business.

o Market potential – We periodically analyze the expected demand for wireless services and whether a country has multiple wireless service providers who are actively seeking to invest in deploying voice and data networks, as well as spectrum auctions that have occurred or that are anticipated to occur and update this analysis when there have been material developments in the industry within the country, whether due to consolidation, spectrum allocation, new participants or changes in the legal and regulatory environment.

o Risk adjusted return criteria – We continually evaluate whether buying or building towers in a country and providing our management and leasing services will meet our return criteria. As part of this analysis, we consider the risk associated with an international market (for example, the impact of foreign currency exchange rates and inflation, real estate, permitting, and taxation risks) and how a particular market meets our long-term strategic and financial objectives and our business generally.

Using our Local Presence to Build Strong Relationships with Major Wireless Service Providers. Given the nature of towers as location-specific communications facilities, we believe that substantially all of what we do is done best locally. Consequently, we have a broad field organization that allows us to develop and capitalize on our experience, expertise, and relationships in each of our local markets which in turn enhances our customer relationships. We seek to replicate this operating model internationally. Due to our presence in local markets, we believe we are well positioned to organically grow our site leasing business and to capture new tower build opportunities in our markets and identify and participate in site development projects across our markets.

Controlling our Underlying Land Positions. We believe that a primary component of a strong site leasing business is the ability to control the underlying land positions. Consequently, we have acquired perpetual easements, long-term leases, or other property interests for the land that underlies our tower structures and intend to continue to do so to the extent available at commercially reasonable prices. We believe that these perpetual easements, long-term leases, and other property interests will increase our margins, improve our cash flow from operations, and minimize our exposure to increases in rents for property interests in the future. As of December 31, 2023, approximately 71% of our tower structures were located on land that we own or control for more than 20 years and the average remaining life under our ground leases and other property interests, including renewal options under our control, was 36 years. As of December 31, 2023, approximately 10.3% of our tower structures had ground leases or other property interests maturing in the next 10 years.

Exploring Opportunities in Evolving Technologies and Ancillary Services. In addition to our traditional tower-related services, we continue to explore ancillary services and evolving technologies that we believe will allow us to create additional value by leveraging our current assets, capabilities, and relationships with wireless service providers and others by expanding SBA’s business within the growing communications ecosystem. This includes supporting efforts for edge data centers and private networks utilizing cellular and Wi-Fi technologies. For example, we are exploring ways to participate in edge computing infrastructure to support existing and future customers’ increasing need to deploy computing capabilities to locations closer to their end users, such as regional data centers and smaller local data centers located at the base of our towers. SBA owns three regional data centers and multiple tower-based data centers in support of this initiative. With regard to open-access networks, SBA works with real estate developers in deploying networks that are accessible throughout a community’s various common areas and resident amenities. We have also partnered with carriers and high-traffic consumer retailers in developing systems for the offloading of data to wireless networks. Additionally, we are exploring opportunities to leverage tower assets and infrastructure to provide energy as a service, including through the deployment of on-site battery backup systems and solar energy solutions.

Industry Developments

We believe that growing wireless data traffic will require wireless service providers to continue to increase the capacity of their networks, and we believe that the continued capacity increases will require our customers to install equipment at new sites and add new equipment at existing sites. We expect that the wireless communications industry will continue to experience growth as a result of the following trends:

Consumers are increasing their demand for wireless connectivity due to the adoption of bandwidth-intensive wireless data applications, such as high-definition streaming, banking, gaming, social networking, enhanced web browsing, and machine-to-machine applications. According to a report published by Ericsson in November 2023, global total mobile data traffic was estimated to reach around 130 exabytes per month by the end of 2023 and is projected to grow by a factor of 3x to reach 403 exabytes per month in 2029.

The velocity of spectrum development is expected to remain dynamic as carriers continue to deploy new bands and optimize bands that are currently in service, both of which activities we expect will require carriers to install equipment at new sites and add new equipment at existing sites. For example, recent and future spectrum auctions, such as the C-Band auction, Auction 108, and Auction 110 in the U.S. are expected to continue to contribute to growth in the upcoming years. In addition, the continued deployment of 5G wireless technologies is expected to increase equipment installation at existing sites.

Consumers list network quality as a key contributor when terminating or changing service. To remain competitive and to decrease subscriber churn rates, wireless carriers have made substantial capital investments into their wireless networks to improve service quality and expand coverage. We expect wireless carriers to continue to expend capital to differentiate their product offerings.

We believe that the worldwide wireless industry will continue to grow and is reasonably well-capitalized, highly competitive and focused on quality and advanced services. Therefore, we expect that we will see a multi-year trend of additional demand for tower space from our customers, which we believe will translate into steady leasing growth for us.

Our Businesses

Site Leasing Services

Our primary focus is the leasing of antenna space on our multi-tenant towers to a variety of wireless service providers under long-term lease contracts in the United States, South America, Central America, Canada, South Africa, the Philippines, and Tanzania. We derive site leasing revenues primarily from wireless service provider tenants. Wireless service providers enter into (1) individual tenant site leases with us, each of which relates to the lease or use of space at an individual site or (2) master lease agreements with us, which provide for the material terms and conditions that will apply to multiple sites; although, in most cases, each individual site under a master lease agreement is also governed by its own site leasing agreement which sets forth pricing and other site specific terms. Our site leasing business generates substantially all of our total segment operating profit, representing 96.2% or more of our total segment operating profit for the past three fiscal years. Our site leasing business is classified into two reportable segments, domestic site leasing and international site leasing.

Domestic Site Leasing

As of December 31, 2023, we owned 17,487 sites in the United States and its territories. For the year ended December 31, 2023, we generated 73.4% of our total site leasing revenue from these sites. We derive domestic site leasing revenues primarily from T-Mobile, AT&T Wireless, Verizon Wireless, and DISH Wireless. In the United States, our tenant leases are generally for an initial term of five years to ten years with multiple renewal periods at the option of the tenant. These tenant leases typically contain specific annual rent escalators, including renewal option periods. Our ground leases and other property interests in the United States are generally for an initial term of five years or more with multiple renewal periods, which are at our option, and provide for specific annual rent escalators. As of December 31, 2023, no U.S. state or territory accounted for more than 10% of our total tower portfolio by tower count, and no U.S. state or territory accounted for more than 10% of our total revenues for the year ended December 31, 2023.

International Site Leasing

We currently own and operate towers in 14 international markets throughout South America, Central America, Canada, South Africa, the Philippines, and Tanzania. As of December 31, 2023, we owned 22,131 sites in our international markets, of which approximately 30% of our total towers are located in Brazil and no other international markets (each country is considered a market) represented more than 5% of our total towers. Our operations in our international markets are primarily in the site leasing business,

Table of Contents

and we continue to focus on growing our international site leasing business through the acquisition and development of towers and organic growth.

We derive international site leasing revenues from all the major carriers in each of the 14 countries in which we operate. Our tenant leases are generally for an initial term of five years to fifteen years with multiple renewal periods at the option of the tenant. Our tenant leases typically either (1) contain specific annual rent escalators, (2) escalate annually in accordance with an inflationary index, or (3) escalate using a combination of fixed and inflation adjusted escalators. In addition, our international site leases may include pass-through charges, such as rent related to ground leases and other property interests, utilities, and fuel.

In our international markets, ground leases and other property interests are generally for an initial term of five years or more with multiple renewal periods, which are at our option. Our ground leases typically either (1) contain specific annual rent escalators or (2) escalate annually in accordance with an inflationary index.

In Ecuador, El Salvador, Guatemala, Nicaragua, and Panama, significantly all of our revenue, expenses, and capital expenditures arising from our activities are denominated in U.S. dollars. Specifically, most of our ground leases and other property interests, tenant leases, and tower-related expenses are paid in U.S. dollars. In our Central American markets, our local currency obligations are principally limited to (1) permitting and other local fees, (2) utilities, and (3) taxes. In Brazil, Canada, Chile, South Africa, and the Philippines, significantly all of our revenue, expenses, and capital expenditures, including tenant leases, ground leases and other property interests, and other tower-related expenses are denominated in local currency. In Colombia, Costa Rica, Peru, and Tanzania, our revenue, expenses, and capital expenditures, including tenant leases, ground leases and other property interests, and other tower-related expenses are denominated in a mix of local currency and U.S. dollars.

Site Development Services

Our site development business, which is conducted in the United States only, is complementary to our site leasing business and provides us the ability to keep in close contact with the wireless service providers that generate substantially all of our site leasing revenue and to capture ancillary revenues that are generated by our site leasing activities, such as antenna and equipment installation at our tower locations. Site development services revenues are earned primarily from providing a full range of end-to-end services to wireless service providers or companies providing development or project management services to wireless service providers. Our services include: (1) network pre-design; (2) site audits; (3) identification of potential locations for towers and antennas on existing infrastructure; (4) support in leasing of the location; (5) assistance in obtaining zoning approvals and permits; (6) tower and related site construction; (7) antenna installation; and (8) radio equipment installation, commissioning, and maintenance. We provide site development services at our towers and at towers owned by others on a local basis through regional, market, and project offices. These market offices are responsible for all site development operations.

Customers

We depend on a relatively small number of customers for our site leasing and site development revenues. The following customers represented at least 10% of our total revenues during the last three years:

|  |  |  | For the year ended December 31,
Percentage of Total Revenues |  |  |  | 2023 |  | 2022 |  | 2021
T-Mobile |  |  |  | 32.5% |  | 36.4% |  | 36.2%
AT&T Wireless |  |  |  | 19.5% |  | 19.6% |  | 22.2%
Verizon Wireless |  |  |  | 14.6% |  | 14.5% |  | 14.7%

In addition to the Big 4 wireless carriers (T-Mobile, AT&T Wireless, Verizon Wireless, and DISH Wireless), we have also provided services or leased space to a number of customers including:

Airtel Tanzania | Liberty Technologies | Tigo
Cellular South | MTN | TIM
Claro | Oi S.A. | Telefonica
Digicel | SouthernLinc | U.S. Cellular
Freedom Mobile | Telkom | Vodacom

Sales and Marketing

Our sales and marketing goals are to:

use existing relationships and develop new relationships with wireless service providers to lease antenna space on and sell related services with respect to our owned towers or managed properties, enabling us to grow our site leasing business; and

successfully bid and win those site development services contracts that will contribute to our operating margins and/or provide a financial or strategic benefit to our site leasing business.

We approach sales on a company-wide basis, involving many of our employees. We have a dedicated sales force that is supplemented by members of our executive management team. Our dedicated salespeople are based regionally as well as in our corporate office. We also rely on our vice presidents, directors, and other operations personnel to sell our services and cultivate customer relationships. Our strategy is to delegate sales efforts by geographic region or to those employees of ours who have the best relationships with our customers. Most wireless service providers have national corporate headquarters with regional and local offices. We believe that wireless service providers make most decisions for site development and site leasing services at the regional and local levels with input from their corporate headquarters. Our sales representatives work with wireless service provider representatives at the regional and local levels and at the national level when appropriate. Our sales staff’s compensation is heavily weighted to incentive-based goals and measurements.

Competition

Domestic Site Leasing – In the U.S., our primary competitors for our site leasing activities are (1) large independent tower companies including American Tower Corporation and Crown Castle International; (2) a number of regional independent tower owners; (3) wireless service providers that own and operate their own towers and lease, or may in the future decide to lease, antenna space to other providers; (4) owners and operators of alternative facilities such as rooftops, outdoor and indoor distributed antenna system (“DAS”) networks, billboards, utility poles, and electric transmission towers; and (5) owners and operators of alternative wireless technology systems and architectures.

International Site Leasing – Internationally, our competition consists of wireless service providers that own and operate their own tower networks, large multinational, national, and regional independent tower companies, and alternative facilities such as rooftop, outdoor and indoor networks, billboards, utility poles, and electric transmission towers.

We believe that tower location and capacity, quality of service, density within a geographic market, and price historically have been and will continue to be the most significant competitive factors affecting the domestic and international site leasing business.

Site Development – The site development business is competitive and price sensitive. We believe that the majority of our competitors in the U.S. site development business operate within local region and market areas, while some firms offer their services nationally. The market includes participants from a variety of market segments offering individual, or combinations of, competing services. The field of competitors includes site development companies, zoning consultants, real estate firms, wireless construction companies, tower owners, telecommunications equipment vendors, which provide end-to-end site development services through multiple subcontractors, and wireless service providers’ internal staff. We believe that providers base their decisions for site development services on a number of criteria, including company experience, price, track record, local reputation, geographic reach, and time for completion of a project.

Human Capital

Our corporate offices are located in Boca Raton, Florida. We also have employees located in our international, regional, and local offices. We consider our employee relations to be good. As of December 31, 2023, we had 1,787 employees of which 644 were based outside of the U.S. and its territories.

Talent Management. We recognize and appreciate the impact that our employees have on the success of our company, our customers, and the communities we serve. We pride ourselves in promoting an inclusive environment that celebrates and encourages all forms of diversity. We also value all those who serve our country and are proud to support military veterans and their families as they transition out of the military. As of December 31, 2023, women represented 41% of our global workforce and 43% of our U.S. employees identified as a racial or ethnic minority.

We recognize the value of attracting, developing, engaging, and retaining our talent. We invest in our employees’ professional growth and development by providing resources and opportunities to develop their skills and expand their expertise. We

see diversity of thought and experiences as critical factors to the long-term success of SBA. As such, we are committed to building a pipeline of future business leaders by strategically recruiting and retaining talent reflective of the communities and markets we serve.

Employee Well-Being. The well-being of our employees is a critical element of our culture, employee engagement, and productivity. Our global compensation and benefits strategy provides programs and resources focused on overall well-being. We offer a competitive total rewards package which includes market-based pay, performance-based annual incentive awards, healthcare and retirement benefits, holiday and paid time off, and tuition assistance.

Health and Safety. At SBA, providing a safe and healthy work environment for the protection of our employees is paramount. The safety of our tower climbers has been a key focus of the company since its founding. In 2013, we opened our internal training facility "Tower U" which provides a rigorous multi-day safety certification program that is required for our employed tower climbers. We are proud that our average lost-day incident rate in the U.S. (days away from work due to workplace incidents) for 2023 was below the 2022 Bureau of Labor benchmark.

Regulatory and Environmental Matters

Federal Regulations. In the U.S., which accounted for 73.4% of our total site leasing revenue for the year ended December 31, 2023, both the Federal Communications Commission (the “FCC”) and the Federal Aviation Administration (the “FAA”) regulate towers. Many FAA requirements are implemented in FCC regulations. These regulations govern the construction, lighting, and painting or other marking of towers, as well as the maintenance, inspection, and record keeping related to towers, and may, depending on the characteristics of particular towers, require prior approval and registration of towers before they may be constructed, altered or used. Wireless communications equipment and radio or television stations antennas operating on towers are separately regulated and may require independent customer licensing depending upon the particular frequency or frequency band used. In addition, any applicant for an FCC tower structure registration (through the FCC’s Antenna Structure Registration System) must certify that, consistent with the Anti-Drug Abuse Act of 1988, neither the applicant nor its principals are subject to a denial of federal benefits because of a conviction for the possession or distribution of a controlled substance. New tower construction also requires approval from the state or local governing authority for the proposed site, compliance with the National Environmental Policy Act (“NEPA”), compliance with the National Historic Preservation Act (“NHPA”), compliance with the Endangered Species Act (“ESA”), and may require notification to the FAA and registration with the FCC.

Pursuant to the requirements of the Communications Act of 1934, as amended, the FCC, in conjunction with the FAA, has developed standards to consider proposals involving new or modified towers. These standards mandate that the FCC and the FAA consider the height of the proposed tower, the relationship of the tower to existing natural or man-made obstructions, and the proximity of the tower to runways and airports. Proposals to construct or to modify existing towers above certain heights must be reviewed by the FAA to ensure the structure will not present a hazard to air navigation. The FAA may condition its issuance of a no-hazard determination upon compliance with specified lighting and/or painting requirements. Towers that meet certain height and location criteria must also be registered with the FCC. A tower that requires FAA clearance will not be registered with the FCC until it is cleared by the FAA. Upon registration, the FCC may also require special lighting and/or painting. Owners of wireless communications towers may have an obligation to maintain painting and lighting or other marking in conformance with FAA and FCC regulations. Tower owners and FCC spectrum licensees that operate on those towers also bear the responsibility of monitoring any lighting systems and notifying the FAA of any lighting outage or malfunction.

Owners and operators of towers may be subject to, and therefore must comply with, environmental laws, including NEPA, NHPA, and ESA. Any licensed radio facility on a tower is subject to environmental review pursuant to NEPA, among other statutes, which requires federal agencies to evaluate the environmental impact of their decisions under certain circumstances. The FCC has issued regulations implementing NEPA. These regulations place responsibility on applicants to investigate potential environmental effects of their operations and to disclose any potential significant effects on the environment in an environmental assessment prior to constructing or modifying a tower and prior to commencing certain operations of wireless communications or radio or television stations from the tower. In the event the FCC determines the proposed structure or operation would have a significant environmental impact based on the standards the FCC has developed, the FCC would be required to prepare an environmental impact statement, which will be subject to public comment. This process could significantly delay the registration of a particular tower.

We generally indemnify our customers against any failure to comply with legal and regulatory compliance requirements applicable to tower owners or operators relating to the construction, modification, or placement of towers. Failure to comply with the applicable requirements may lead to civil penalties.

The Telecommunications Act of 1996 amended the Communications Act of 1934 by preserving state and local zoning authorities’ jurisdiction over the construction, modification, and placement of towers. The law, however, limits local zoning authority by prohibiting any action that would discriminate among different providers of personal wireless services or ban altogether the

6

Table of Contents

construction, modification or placement of radio communication towers. Finally, the Telecommunications Act of 1996 and the FCC’s rules implementing that Act require the federal government to help licensees for wireless communications services gain access to preferred sites on federal property for their facilities. This may require that federal agencies and departments work directly with licensees to make federal property available for tower facilities.

Operators of towers must also take into consideration certain radio frequency (“RF”) emissions regulations that impose a variety of procedural and operating requirements. Certain proposals to operate wireless communications and radio or television stations from tower structures are also reviewed by the FCC to ensure compliance with requirements relating to human exposure to RF emissions.

Environmental Regulation. As an owner and operator of real property, we are subject to certain environmental laws that impose strict, joint and several liability for the cleanup of on-site or off-site contamination and related personal injury or property damage. We are also subject to certain environmental laws that govern tower placement and may require pre-construction environmental studies. Our screening for environmental impacts includes evaluation of those of our tower site locations (1) that might be located in a wilderness area or a wildlife preserve, (2) that might affect threatened and endangered species or their habitat (ESA), (3) that might affect properties included in, or eligible for inclusion, in the National Register of Historic Places (NRHP) or Indian religious and cultural sites, (4) that might affect World Heritage areas and IUCN Category I-IV protected areas, (5) that will be located in a floodplain and where facility equipment will not be placed at least one foot above the base flood elevation of the floodplain, (6) whose construction will involve significant changes in surface features (e.g., in wetlands, water diversions, considerable ground disturbance, deforestation), (7) that might affect migratory birds if the towers are over 450 feet, (8) that involve high-intensity lighting in a residential area or would cause RF radiation over FCC-established limits, and (9) that would involve similar considerations under the laws or best practices of our international markets. When a tower site is impacted by any of the listed categories, we promptly complete an environmental assessment and obtain approval from the appropriate regulatory agency, which may include steps to mitigate the impact of construction or operation of the site. Our regional site managers regularly inspect our tower sites and report on any environmental or compliance issues. This ensures we minimize our environmental impact and remain compliant during the operational life of our assets.

We believe that we are in substantial compliance with and we have no material liability under any applicable environmental laws. These costs of compliance with existing or future environmental laws and liability related thereto may have a material adverse effect on our prospects, financial condition or results of operations.

State and Local Regulations. Most states regulate certain aspects of real estate acquisition, leasing activities, and construction activities. Where required, we conduct the site acquisition portions of our site development services business through licensed real estate brokers’ agents, who may be our employees or hired as independent contractors, and conduct the construction portions of our site development services through licensed contractors, who may be our employees or independent contractors. Local regulations include city and other local ordinances, zoning restrictions, and restrictive covenants imposed by community developers. These regulations vary greatly from jurisdiction to jurisdiction, but typically require tower owners to obtain approval from local officials or community standards organizations, or certain other entities prior to tower construction and establish regulations regarding maintenance and removal of towers. FCC rules establish presumptively reasonable time periods for state and local authorities to act on applications to collocate a facility or deploy a facility, such as a tower. In addition, many local zoning authorities require tower owners to post bonds or cash collateral to secure their removal obligations. Local zoning authorities generally have been unreceptive to construction of new towers in their communities because of the height and visibility of the towers, and have, in some instances, instituted moratoria. However, in August 2018, the FCC issued a declaratory ruling stating that express and de facto moratoria on deployment of telecommunications facilities violate the Communications Act. This FCC ruling has been affirmed by a federal appellate court.

International Regulations. Regulatory regimes outside of the U.S. and its territories vary by country and locality; however, these regulations typically require tower owners and/or licensees to obtain approval from local officials or government agencies prior to tower construction or modification or the addition of a new antenna to an existing tower. Additionally, some regulations include ongoing obligations regarding painting, lighting, and maintenance. Our international operations may also be subject to limitations on foreign ownership of land in certain areas. Based on our experience to date, these regimes have been similar to, but not more rigorous, burdensome or comprehensive than, those in the U.S. Non-compliance with such regulations may lead to monetary penalties or deconstruction orders. Our international operations are also subject to various regulations and guidelines regarding employee relations and other occupational health and safety matters. As we expand our operations into additional international geographic areas, we will be subject to regulations in these jurisdictions.

ITEM 1A. RISK FACTORS

Risks Related to Our Business

If our wireless service provider customers combine their operations to a significant degree, our future operating results, ability to service our indebtedness, and stock price could be adversely affected.

Our domestic and international wireless service providers have and may continue to be subject to consolidation pressures arising from competitive pressures, spectrum limitations, the significant capital expenditures necessary to build out national networks on evolving technology and governmental policies seeking to limit the telecommunications infrastructure footprint within a market. Significant consolidation among our wireless service provider customers has resulted, and is expected to continue to result, in our customers failing to renew existing leases for tower space as a result of overlapping coverage, nearby locations, or reducing future capital expenditures in the aggregate because their existing networks and expansion plans may overlap or be very similar.

Historically, the three largest domestic wireless service providers, T-Mobile, AT&T Wireless, and Verizon Wireless, have grown through acquisitions of other wireless service providers. As a result, the combined companies have rationalized duplicative parts of their networks, or networks have been discontinued. During 2020, the consolidation of T-Mobile and Sprint was completed, and we began to experience non-renewal (“churn”) of certain leases as a result of this merger. We currently expect that this churn will represent an aggregate of between $125.0 million and $150.0 million of cash site leasing revenue from 2024 through 2028. The aggregate churn estimate includes both overlapping and adjacent Sprint leases. We do not expect the annual churn to be uniform over this period as the timing of the churn will depend on termination rights as well as the needs of the carrier.

Internationally, Oi S.A. (“Oi”) in Brazil and some of our wireless service providers in Central America have recently used consolidation to address financial or other competitive pressures. For example, in Brazil, Oi’s restructuring, which was substantially completed in December 2022, resulted in the sale of all of Oi’s wireless assets to the three other telecommunications providers in Brazil: Telefonica, Claro, and TIM. We currently expect this sale to result in churn of between $13.0 million and $23.0 million (including churn on our acquired sites from Grupo TorreSur (“GTS”)). The range excludes the impact of $10.0 million in churn related to TIM experienced in 2023. While our leases with Oi have an average of five years remaining on the current term, we expect that churn associated with these leases could occur sooner than the current term end dates depending upon negotiations with each of the carriers.

If our domestic or international wireless service provider customers continue to consolidate, these consolidations could significantly impact the number of our tower leases that are not renewed or the number of new leases that our wireless service provider customers require to expand their networks, which could materially and adversely affect our future operating results.

We depend on a relatively small number of customers for most of our revenue, and the loss, consolidation or financial instability of any of our significant customers may materially decrease our revenue and adversely affect our financial condition.

We derive a significant portion of our revenue from a small number of customers. Consequently, a reduction in demand for site leasing, reduced future capital expenditures or operating expenses on the networks, or the loss, as a result of bankruptcy, merger with other customers of ours or otherwise, of any of our largest customers could materially decrease our revenue and have an adverse effect on our growth. Our growth projections are based on our beliefs regarding future revenue from these customers, and such projections could be adversely affected by the loss, consolidation or financial instability of these customers.

We derive revenue through numerous site leasing and site development contracts. In the United States and our international markets, each site leasing contract relates to the lease of space at an individual tower and is generally for an initial term of five years to fifteen years with multiple renewal periods at the option of the tenant. However, if any of our significant site leasing customers were to experience financial difficulty, substantially reduce their capital expenditures or reduce their dependence on leased tower space on our sites and fail to renew their leases with us, our revenues, future revenue growth and results of operations would be adversely

affected. For example, in 2023 Oi entered into its second judicial recovery process related to Oi’s wireline business due to financial difficulties. Oi’s wireline business and their concession rights from the Federal Republic of Brazil to the land underneath 2,113 of our towers continue to be subject to the judicial recovery process. We currently have approximately $24 million in annual revenue from Oi’s wireline business, which is principally contractually committed through 2048. It is unclear the extent to which the judicial recovery process may affect the amount, term or timing of the remaining Oi wireline revenue or our rights to the land underlying the affected towers. In addition, many of our tenants in our international markets are subsidiaries of global telecommunications companies. These subsidiaries may not have the explicit or implied financial support of their parent entities, which may impact their creditworthiness.

Our site development customers engage us on a project-by-project basis, and a customer can generally terminate an assignment at any time without penalty. In addition, a customer’s need for site development services can decrease, and we may not be successful in establishing relationships with new customers. Furthermore, our existing customers may not continue to engage us for additional projects.

While the U.S. wireless service provider market has recently reduced to three nationwide wireless service providers, AT&T Wireless, T-Mobile, and Verizon Wireless, we and most of the industry anticipate that the number of nationwide wireless service providers will increase to four again once DISH Wireless successfully builds out its nationwide network. If DISH Wireless is unable to successfully build-out its wireless network or is unable to successfully compete for customers once its network is built out, then our dependence on the three U.S. wireless service providers for our financial and operational growth will be exacerbated. Additionally, as a result of the Oi restructuring discussed above, our operations in Brazil are significantly dependent on three wireless service providers.

The following is a list of significant customers (representing at least 10% of revenue in any of the last three years) and the percentage of our total revenues for the specified time periods derived from these customers:

|  |  |  | For the year ended December 31,
Percentage of Total Revenues |  |  |  | 2023 |  | 2022 |  | 2021

If our wireless service provider customers are unable to access sufficient capital, or unwilling based on the economic cost of such capital or other reasons, to invest in their infrastructure or spectrum, it could reduce our ability to meet our growth expectations.

Each wireless service provider must have substantial capital resources and capabilities to deploy new spectrum in their wireless networks, including licenses for spectrum. Increasing interest rates have impacted, and are expected to continue to impact, the ability and willingness of wireless service providers to incur capital expenditures at historic levels to expand their networks, which would adversely affect our future revenue growth rates. For example, certain providers have said they expect to decrease capital expenditures in 2024. Higher interest rates increase the economic cost of available capital and may make it less favorable for wireless service providers to obtain capital for investment. If some or all of our wireless service provider customers, or potential customers, are unable to access sufficient capital, or unwilling based on the economic cost of such capital, to invest in the expansion of their networks, it could adversely affect our revenue growth. Wireless capital expenditures may also be adversely impacted by service provider decisions on debt levels, dividends, free cash flow goals, and a variety of other factors.

Our variable rate indebtedness and refinancing obligations subject us to interest rate risk, which could cause our debt service obligations to increase significantly.

Pursuant to the terms of our Credit Agreement, the interest rate that we pay on indebtedness incurred under the Revolving Credit Facility and the Term Loans varies based on a fixed margin over either a base rate or a Eurodollar rate which references the SOFR rate. As of December 31, 2023, this indebtedness represented approximately $2.4 billion, or 19.8% of our total indebtedness. As a result, we are exposed to interest rate risk. Interest rates, including SOFR, fluctuate periodically and as such may increase in future periods. If interest rates increase, our debt service obligations on the variable rate indebtedness will increase even though the amount borrowed remained the same, and our net income and cash flows, including cash available for servicing our indebtedness, will correspondingly decrease. Due to inflationary pressures on the U.S. economy and governmental action to combat inflation, interest rates have risen significantly in the past two years, and interest rates may increase in the future, which will likely increase our interest expense on our variable rate indebtedness and decrease our net income. In addition, increasing interest rates may result in higher interest expense on our current fixed rate indebtedness upon a refinancing.

Although we have used interest rate swaps to mitigate our interest rate risk from time to time, we may not maintain interest rate swaps with respect to all of our variable rate indebtedness, and any swaps we enter into may not fully mitigate our interest rate risk. Furthermore, the increase in our use of derivative instruments increases our exposure to counterparty credit risk to the extent that a counterparty to the instrument fails to meet or perform the terms of the instrument. Throughout 2023, we had interest rate swaps on a portion of our 2018 Term Loan that fixed $1.95 billion in notional value receiving interest at (i) one month LIBOR plus 175 basis points and paying an all-in fixed rate of 1.874% per annum through July 31, 2023 and (ii) one month Term SOFR plus 185 basis points (inclusive of a credit spread adjustment (“CSA”) of 0.10%) and paying an all-in fixed rate of 1.900% per annum from August 1, 2023 through March 31, 2025. On January 25, 2024, we issued a new $2.3 billion, seven-year, senior secured Term Loan B (“2024 Term Loan”) which replaced the 2018 Term Loan. Including the impact of the interest rate swap, the 2024 Term Loan receives interest at one month Term SOFR plus 200 basis points and pays an all-in fixed rate of 2.050% per annum from January 25, 2024 through March 31, 2025. On November 3, 2023, we, through our wholly owned subsidiary, SBA Senior Finance II, entered into a forward-starting interest rate swap agreement which will swap $1.0 billion of notional value accruing interest at one month Term SOFR plus 200 basis points for an all-in fixed rate of 5.830% per annum. The swap has an effective start date of March 31, 2025 and a maturity date of April 11, 2028.

We have a substantial level of indebtedness which may have an adverse effect on our business or limit our ability to take advantage of business, strategic or financing opportunities.

As indicated below, we have and will continue to have a significant amount of indebtedness. The following table sets forth our total principal amount of debt and shareholders’ deficit as of December 31, 2023 and 2022:

|  | As of December 31,
|  | 2023 |  | 2022
|  | (in thousands)
Total principal amount of indebtedness |  | $ | 12,388,000 |  | $ | 12,952,000
Shareholders' deficit |  | $ | (5,170,882) |  | $ | (5,276,315)

Our substantial level of indebtedness increases the possibility that we may be unable to generate cash sufficient to pay the principal, interest, or other amounts due on our indebtedness. Subject to certain restrictions under our existing indebtedness, we and our subsidiaries may also incur significant additional indebtedness in the future, which may have the effect of increasing our total leverage.

Table of Contents

As a consequence of our indebtedness, (1) demands on our cash resources may increase, (2) we are subject to restrictive covenants that further limit our financial and operating flexibility, and (3) we may choose to institute self-imposed limits on our indebtedness based on certain considerations including market interest rates, our relative leverage and our strategic plans. For example, as a result of our substantial level of indebtedness and the uncertainties arising in the credit markets and the U.S. economy:

•we may be more vulnerable to general adverse economic and industry conditions;

•we may have to pay higher interest rates upon refinancing or on our variable rate indebtedness if interest rates rise, thereby reducing our cash flows;

•we may find it more difficult to obtain additional financing to fund future working capital, capital expenditures, and other general corporate requirements that would be in our best long-term interests;

•we may be required to dedicate a substantial portion of our cash flow from operations to the payment of principal and interest on our debt, reducing the available cash flow to fund other investments, including share repurchases, tower acquisition, and new build capital expenditures, or to satisfy our REIT distribution requirements;

•we may have limited flexibility in planning for, or reacting to, changes in our business or in the industry;

•we may have a competitive disadvantage relative to other companies in our industry that are less leveraged; and

•we may be required to sell debt or equity securities or sell some of our core assets, possibly on unfavorable terms, in order to meet payment obligations.

Increasing competition in the tower industry may create pricing pressures or result in non-renewals that may materially and adversely affect us.

Our industry is highly competitive, and our wireless service provider customers sometimes have alternatives for leasing antenna space. We believe that tower location and capacity, quality of service, density within a geographic market, and price historically have been and will continue to be the most significant competitive factors affecting the site leasing business. However, competitive pricing pressure for tenants on towers from our competitors have and may in the future result in us entering into master lease agreements that may impact certain terms of existing or future individual site lease agreements. Terms that may be impacted include pricing discounts, term concessions, and equipment rights. Competition for tenants, whether or not resulting in master lease agreements, may materially and adversely affect our lease rates or lead to non-renewal of existing leases. Furthermore, pricing pressures could lead to more prevalent network sharing, both domestically and internationally, which could reduce the demand for our tower space or lead to non-renewals of existing leases. In addition, the increasing number of towers (1) may provide customers the ability to relocate their antennas to other towers if they determine that a more suitable, efficient or economical location exists, which could lead to non-renewal of existing leases, or (2) may adversely impact our ability to enter into new customer leases. This impact may be exacerbated if competitors construct towers near our existing towers. Any of these factors could materially and adversely affect our growth rate and our future operations.

In the site leasing business, we compete with:

•wireless service providers that own and operate their own towers and lease, or may in the future decide to lease, antenna space to other providers;

•national and regional tower companies who may be substantially larger and have greater financial resources than we do;

•international tower companies who have been in the international market for a longer period of time than we have; and

•alternative facilities such as rooftops, outdoor and indoor DAS networks, billboards, and electric transmission towers.

The site development segment of our industry is also competitive. There are numerous large and small companies that offer one or more of the services offered by our site development business. As a result of this competition, margins in this segment may come under pressure. Many of our competitors have lower overhead expenses and therefore may be able to provide services at prices that we consider unprofitable. If margins in this segment were to decrease, our consolidated revenues and our site development segment operating profit could be adversely affected.

A slowdown in demand for wireless services could materially and adversely affect our future growth and revenues.

We expect a significant portion of our future revenue growth will result from investments in the deployment of new or fallow spectrum by our wireless service provider customers, including the build-out by DISH Wireless of a fourth nationwide network in the U.S. Wireless service providers typically invest in their networks in response to consumer demand for additional or higher quality service. Potential periods of economic downturn or decreases in discretionary income may also reduce consumer spending on, and demand for additional or higher quality wireless services. If consumers significantly reduce their use of wireless services or fail to widely adopt and use new wireless technologies and their products and applications, our wireless service provider customers could experience a reduction in the rate of growth of or a decrease in demand for their services and therefore reduce the amount they invest in their network. In addition, a slowdown may increase competition in the tower industry which may in turn increase our exposure to the risks described herein.

Increasing competition may negatively impact our ability to grow our communication site portfolio long term.

We intend to continue growing our tower portfolio, domestically and internationally, through acquisitions and new builds. Our ability to meet our growth targets significantly depends on our ability to build or acquire existing towers that meet our investment requirements. Traditionally, our acquisition strategy has focused on acquiring towers from smaller tower companies, independent tower developers, and wireless service providers. However, as a result of consolidation in the tower industry, there are fewer of these tower transactions available, and there is more competition to acquire existing towers. Increased competition for acquisitions may result in fewer acquisition opportunities for us, higher acquisition prices, and increased difficulty in negotiating and acquiring such towers. Furthermore, to the extent that the tower acquisition opportunities are for significant tower portfolios, some of our competitors and financial sponsors are significantly larger and have greater financial resources than we do. Finally, laws regulating competition, domestically and internationally, may limit our ability to acquire certain portfolios. As a result of these risks, the cost of acquiring these towers may be higher than we expect, or we may not be able to meet our annual and long-term tower portfolio growth targets. If we are not able to successfully address these challenges, we may not be able to materially increase our tower portfolio in the long-term through acquisitions.

Our ability to build new towers is dependent upon our wireless customers’ needs and the availability of sufficient capital to fund construction, our ability to locate, and acquire at commercially reasonable prices, attractive locations for such towers and our ability to obtain the necessary zoning and permits. Local regulations, including municipal or local ordinances, zoning restrictions and restrictive covenants imposed by community developers, vary greatly, but typically require antenna tower and structure owners to obtain approval from local officials or community standards organizations prior to tower or structure construction or modification. With respect to our international new builds, our tower construction may be delayed or halted as a result of local zoning restrictions, inconsistencies between laws or other barriers to construction in international markets. Due to these risks, it may take longer to complete our new tower builds than anticipated, domestically and internationally, and the costs of constructing these towers may be higher than we expect, or we may not be able to add as many towers as planned in 2024. If we are not able to increase our new build tower portfolio as anticipated, it could negatively impact our ability to achieve our financial goals.

Our international operations are subject to economic, political, and other risks that could materially and adversely affect our revenues or financial position.

Our current business operations in developing markets, and our expansion into any other international markets in the future, could result in adverse financial consequences and operational problems not typically experienced in the United States. The site leasing revenues generated by our international operations were approximately 24.7% of our total revenues during the year ended December 31, 2023, and we anticipate that our revenues from our international operations will continue to grow in the future. Accordingly, our business is and will be subject to risks associated with doing business internationally, including:

•laws and regulations that dictate how we operate our towers and conduct business and which may be uncertain, be inconsistent or adversely change, including those relating to zoning, construction, maintenance and environmental matters, and laws related to ownership of real property;

•changes in a specific country’s or region’s political or economic conditions, including inflation or currency devaluation;

•laws affecting telecommunications infrastructure including the sharing of such infrastructure;

•laws and regulations that tax or otherwise restrict repatriation of earnings or other funds or otherwise limit distributions of capital;

•changes to existing or new domestic or international tax laws, new or significantly increased municipal fees directed specifically at the ownership and operation of towers, which may be applied and enforced retroactively and could materially affect the profitability of our operations;

•expropriation and governmental regulation restricting foreign ownership or requiring reversion or divestiture;

•governmental regulations and restrictions impacting tower licenses, spectrum licenses and concessions, including additional restrictions on the use or revocation of such licenses, concessions or spectrum and additional conditions to receive or maintain such licenses;

•laws and regulations governing our employee relations, including occupational health and safety matters and employee compensation and benefits matters;

•our ability to comply with, and the costs of compliance with, anti-bribery laws such as the Foreign Corrupt Practices Act and similar local anti-bribery laws;

•our ability to negotiate, and enforce, leases or other contracts on similar terms as that of our U.S. operations;

•uncertainties regarding legal or judicial systems, including inconsistencies between and within laws, regulations and decrees, and judicial application thereof, and delays in the judicial process;

•challenges arising from less-developed infrastructure in certain markets;

•difficulty in recruiting and retaining trained personnel; and

•our ability to provide power to our sites in those international markets that do not have an available electric grid at our tower sites.

We are also exposed to risks operating in countries with high levels of inflation, including the risk that inflation rates exceed our fixed escalator percentages in markets where our leases include fixed escalators and the risk that adverse economic conditions may discourage growth in consumer demand and consequently reduce our customers’ demand for our site leasing services. As of December 31, 2023, approximately 15.2% of our tenant leases in our international markets include fixed escalators.

Currency fluctuations may negatively affect our results of operations.

In Ecuador, El Salvador, Guatemala, Nicaragua, and Panama, significantly all of our revenue, expenses, and capital expenditures arising from our activities are denominated in U.S. dollars. Specifically, most of our ground leases and other property interests, tenant leases, and tower-related expenses are paid in U.S. dollars. In Brazil, Canada, Chile, South Africa, and the Philippines, significantly all of our revenue, expenses, and capital expenditures, including tenant leases, ground leases and other property interests, and other tower-related expenses are denominated in local currency. In Colombia, Costa Rica, Peru, and Tanzania, our revenue, expenses, and capital expenditures, including tenant leases, ground leases and other property interests, and other tower-related expenses are denominated in a mix of local currency and U.S. dollars. Our foreign currency denominated revenues and expenses are translated into U.S. dollars at average exchange rates for inclusion in our consolidated financial statements.

For the year ended December 31, 2023, approximately 26.6% of our total site leasing revenue was generated by our international operations, of which 23.3% was generated in non-U.S. dollar currencies, including 15.6% which was denominated in Brazilian Reais. The exchange rates between our foreign currencies and the U.S. Dollar have fluctuated significantly in recent years and may continue to do so in the future. For example, the Brazilian Real has historically been subject to substantial volatility and strengthened 3.2% when comparing the average rate for the years ended December 31, 2023 and 2022. This fluctuation has affected, and may in the future continue to affect, our reported results of operations.

Changes in exchange rates between these local currencies and the U.S. dollar will affect the recorded levels of site leasing revenue, segment operating profit, assets and/or liabilities. Volatility in foreign currency exchange rates can also affect our ability to plan, forecast, and budget for our international operations and expansion efforts.

Furthermore, we have intercompany loan agreements with our foreign subsidiaries to borrow in U.S. Dollars. As of December 31, 2023 and 2022, the aggregate amount outstanding under the intercompany loan agreements subject to remeasurement with our foreign subsidiaries was $1.3 billion and $1.5 billion, respectively. In accordance with Accounting Standards Codification (“ASC”) 830, we remeasure foreign denominated intercompany loans with the corresponding change in the balance being recorded in Other income (expense), net in our Consolidated Statements of Operations as settlement is anticipated or planned in the foreseeable future. Consequently, if the U.S. Dollar strengthens against the Brazilian Real, South African Rand, or the Tanzanian Shilling, our results of operations would be adversely affected. For the years ended December 31, 2023 and 2022, we recorded a $52.4 million gain and a $12.9 million gain, net of taxes, respectively, on the remeasurement of intercompany loans due to changes in foreign exchange rates. For the year ended December 31, 2023, we funded $4.2 million and repaid $223.4 million under our intercompany loan agreements. Subsequent to year end, we repaid an additional $15.0 million under our intercompany loan agreements.

Delays in the roll-out of new spectrum or deployment of new technologies could materially and adversely affect our future growth and revenues.

Our ability to grow is dependent on the ability and willingness of our wireless service provider customers to invest in the roll-out of new spectrum or new technologies. Much of the future capital investment by domestic wireless service providers is expected to result from the roll-out of 5G. However, the roll-out of prior spectrum, including 3G and 4G was often delayed and the roll-out of this spectrum may encounter similar interruptions. For example, in January 2022, several major U.S. wireless carriers had to temporarily delay deployment of new wireless facilities that were meant to facilitate the evolution of their wireless networks to 5G technology in response to concerns of the aviation industry that those 5G facilities could interfere with equipment used for aviation and could impede aviation safety. Although this issue has been substantially resolved, the deployment of new technologies has resulted, and may continue to result, in unexpected issues that could increase the cost or delay the deployment of new technologies.

The FCC continues to auction new bands of spectrum, including C-Band, Auction 108, and Auction 110. Our customers have been and are expected to be the primary winners of these auctions and subsequently deploy this spectrum on our portfolio which would provide us with a revenue growth opportunity. Any delays or failure of these auctions could negatively impact future demand for our towers. Similarly, any delays in the clearing or availability of this spectrum subsequent to these auctions could delay the related demand for our towers.

New technologies or network architecture or changes in a customer’s business model may reduce demand for our wireless infrastructure or negatively impact our revenues.

Improvements or changes in the efficiency, architecture, and design of wireless networks or changes in a wireless service provider customer's business model may reduce the demand for our wireless infrastructure. Also, as customers deploy increased capital to develop and implement new technologies, they may allocate less of their budgets to lease space on our towers. For example, new technologies that may promote network sharing, joint development, or resale agreements by our wireless service provider customers, such as signal combining technologies or network functions virtualization, may reduce the need for our wireless infrastructure, or may result in the decommissioning of equipment on certain sites because portions of the customers' networks may become redundant. In addition, other technologies and architectures, such as WiFi, DAS, femtocells, other small cells, or satellite (such as low earth orbiting) and mesh transmission systems may, in the future, serve as substitutes for, or alternatives to, the traditional macro site communications architecture that is the basis of substantially all of our site leasing business. The majority of our tower portfolio comprises traditional macro sites and therefore is not as diversified into non-macro sites and other technologies and architectures as some of our competitors. In addition, new technologies that enhance the range, efficiency, and capacity of wireless equipment could reduce demand for our wireless infrastructure. For example, our wireless service provider customers have engaged in increased use of network sharing, roaming, or resale arrangements, resulting in reduced capital spending or a decision to sell or not renew their spectrum licenses or concessions. Any significant reduction in demand for our wireless infrastructure resulting from new technologies or new architectures or changes in a customer's business model may negatively impact our revenues or otherwise have a material adverse effect on our business and results of operations. Any such event may have a disproportionate impact on our business compared to our competitors, whose portfolios may be more technologically and architecturally diversified than ours. In addition, while we are exploring and investing in ancillary services and emerging technologies, including our mobile edge computing initiative and private networks, those investments may not prove to be profitable.

These factors could also have a material adverse effect on our growth rate since growth opportunities and demand for our tower space as a result of new technologies may not be realized at the times or to the extent anticipated. Any of these factors could have a material adverse effect on our business, results of operations, and financial condition.

If we are unable to protect our rights to the land under our towers, it could adversely affect our business and operating results.

Our real property interests relating to the land under our tower structures consist primarily of leasehold and sub-leasehold interests, fee interests, easements, licenses, rights-of-way, and other similar interests. From time to time, we experience disputes with landowners regarding the terms of the agreements for the land under our tower structures, which can affect our ability to access and operate such towers. Further, landowners may not want to renew their agreements with us, they may lose their rights to the land, or they may transfer their property interests to third parties, including property interest aggregators and our competitors, which could affect our ability to renew agreements on commercially viable terms or at all. Further, for various reasons, title to property interests in some of the foreign jurisdictions in which we operate may not be as certain as title to our property interests in the United States.

For example, the land underneath 3,868 towers subject to non-terminable leases in Brazil is currently subject to concessions from the Federal Republic of Brazil. Brazil adopted a new telecommunications law in 2021 that provides that these concessions may be converted into perpetual authorizations at the end of their terms and that provides a seller and/or the Brazilian government rights to sell the land underlying these assets. The amount, if any, that would be required to be paid to convert these concessions into authorizations and/or that we would be required to pay to purchase such interests has not yet been determined. At the end of the concession terms, in the event our customers have not opted to convert their concessions into authorizations, the Brazilian government may terminate the concessions and take possession of the land and the tower on such land. If the concessions are not renewed and we are unable to purchase the land, then our site leasing revenue from co-located tenants would terminate prior to the end of such leases. Of these 3,868 towers, 2,113 towers are located on land that is subject to a concession with Oi from the Federal Republic of Brazil with respect to which we have negotiated a right of first refusal. As discussed above, in 2023 Oi entered into its second judicial recovery process related to its wireline business due to financial difficulties and their concession rights to the land underneath 2,113 of our towers continues to be subject to the recovery process. It is unclear the extent to which the recovery process may affect our rights to the land underlying the affected towers. For the year ended December 31, 2023, we generated approximately 14.7% of our total international site leasing revenue from these 3,868 towers.

As of December 31, 2023, the average remaining life under our ground leases and other property interests, including renewal options under our control, was approximately 36 years, and approximately 10.3% of our tower structures have ground leases or other property interests maturing in the next 10 years. Failure to protect our rights to the land under our towers may have a material adverse effect on our business, results of operations or financial condition.

We may not be able to fully recognize the anticipated benefits of towers that we acquire.

A key element of our growth strategy is to increase our tower portfolio through acquisitions. We are subject to a number of risks and uncertainties as a result of those acquisition activities. These activities may fail to achieve the benefits we expected from the acquisition, or the acquired assets may not meet our internal guidelines for current and future returns, particularly if we are required to place greater reliance on the financial and operational representations and warranties of the sellers in individually material acquisitions. The impact of these risks is further enhanced in acquisitions of towers in international markets, where it may be more difficult to verify all relevant information with respect to the assets being acquired. These risks could adversely affect our revenues and results of operations.

In addition, acquisitions which would be material in the aggregate may exacerbate the risks inherent with our growth strategy, such as (1) an adverse financial impact if the acquired towers do not achieve the projected financial results, (2) the impact of unanticipated costs associated with such acquisitions on our results of operations, (3) increased demands on our cash resources that may impact our ability to explore other opportunities, (4) undisclosed and assumed liabilities that we may be unable to recover, (5) an adverse impact on our existing customer relationships, (6) additional expenses and exposure to new regulatory, political, and economic risks, and (7) diversion of managerial attention.

As part of new acquisitions of tower assets in natural disaster-prone areas, we may assess asset exposure to physical risks and inspect assets for signs of climate-related damage to help us understand the degree of exposure to tornadoes, fires, hurricanes, floods, and earthquakes the site may face over the longer term. However, our environmental due diligence may not uncover all natural disaster-related risks to tower assets that we acquire, and our mitigation measures may not be successful, which could require us to incur significant expenditures and may have an adverse effect on our operations or financial condition.

The process of integrating any acquired towers into our operations is also subject to a number of risks and financial impacts, including unforeseen operating difficulties, large expenditures, diversion of management attention, the loss of key customers and/or personnel, our inability to retain or timely find suitable replacements for key employees and management needed to operate the acquired business, and exposure to unanticipated liabilities. These risks may be exacerbated in acquisitions of a material number of towers. There can be no assurance that we will be successful in integrating domestic and international acquisitions into our existing business.

The documents governing our indebtedness contain restrictive covenants that could adversely affect our business by limiting our flexibility.

The indentures governing the 2020 Senior Notes and the 2021 Senior Notes, the Senior Credit Agreement, and the agreement for the mortgage loan underlying the Tower Securities contain restrictive covenants imposing significant operational and financial restrictions on us, including restrictions that may limit our ability to engage in acts that may be in our long-term best interests. Among other things, the covenants under each instrument limit our ability to:

•merge, consolidate or sell assets;

•make restricted payments, including pay dividends or make other distributions;

•enter into transactions with affiliates;

•enter into sale and leaseback transactions; and

•issue guarantees of indebtedness.

Additionally, the agreement governing the mortgage loan relating to our Tower Securities contains financial covenants that require that the borrowers maintain, on a consolidated basis, a minimum debt service coverage ratio. To the extent that the debt service coverage ratio, as of the end of any calendar quarter, falls to 1.30 times or lower, then all cash flow in excess of amounts required to make debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other payments required under the loan documents, referred to as “excess cash flow,” will be deposited into a reserve account instead of being released to the borrowers. The funds in the reserve account will not be released to the borrowers unless the debt service coverage ratio exceeds 1.30 times for two consecutive calendar quarters. If the debt service coverage ratio falls below 1.15 times as of the end of any calendar quarter, then an “amortization period” will commence and all funds on deposit in the reserve account will be applied to prepay the mortgage loan until such time that the debt service coverage ratio exceeds 1.15 times for a calendar quarter.

The Senior Credit Agreement, as amended, requires SBA Senior Finance II LLC (“SBA Senior Finance II”) to maintain specific financial ratios, including (1) a ratio of Consolidated Net Debt to Annualized Borrower EBITDA not to exceed 6.5 times for any fiscal quarter and (2) a ratio of Annualized Borrower EBITDA to Annualized Cash Interest Expense (calculated in accordance with the Senior Credit Agreement) of not less than 2.0 times for any fiscal quarter.

These covenants could place us at a disadvantage compared to some of our competitors which may have fewer restrictive covenants and may not be required to operate under these restrictions. Further, these covenants could have an adverse effect on our business by limiting our ability to take advantage of financing, new tower development, merger and acquisitions, or other opportunities. If we fail to comply with these covenants, it could result in an event of default under our debt instruments. If any default occurs, all amounts outstanding under our outstanding notes and the Senior Credit Agreement may become immediately due and payable.

Our dependence on our subsidiaries for cash flow may negatively affect our business.

We are a holding company with no business operations of our own. Our only significant assets are, and are expected to be, the outstanding capital stock and membership interests of our subsidiaries. We conduct, and expect to continue conducting, all of our business operations through our subsidiaries. Accordingly, our ability to pay our obligations is dependent upon dividends and other distributions from our subsidiaries to us. Most of our indebtedness is owed directly by our subsidiaries, including the mortgage loan underlying the Tower Securities and any amounts that we may borrow under the Senior Credit Agreement. Consequently, the first use of any cash flow from operations generated by such subsidiaries will be payments of interest and principal, if any, under their respective indebtedness. Other than the cash required to repay amounts due under our 2020 Senior Notes and 2021 Senior Notes and funds to be utilized for stock repurchases and dividend payments, we currently expect that substantially all the earnings and cash flow of our subsidiaries will be retained and used by them in their operations, including servicing their respective debt obligations. The ability of our operating subsidiaries to pay dividends or transfer assets to us is restricted by applicable state law and contractual restrictions, including the terms of their outstanding debt instruments.

The loss of the services of key personnel or a significant number of our employees may negatively affect our business.

Our success depends to a significant extent upon performance and active participation of our key personnel. Effective December 31, 2023, Jeffrey A. Stoops retired from his position as President and Chief Executive Officer, and Brendan T. Cavanagh assumed the position of Chief Executive Officer. Marc Montagner assumed the position of Executive Vice President and Chief Financial Officer, which was previously held by Mr. Cavanagh. Additionally, Jason Silberstein, our Executive Vice President, Site Leasing, will retire effective August 1, 2024. In connection with the transition of these senior executive officers, there is a risk that our new executives may not have the same level of institutional knowledge or industry relationships as their predecessors or that we may not be able to retain these executives long-term. If any of our key personnel were to leave or retire, we may not be able to find an appropriate replacement on a timely basis and our results of operations could be negatively affected. Further, the loss of a significant number of employees or our inability to hire a sufficient number of qualified employees could have a material adverse effect on our business.

Our business is subject to government regulations and changes in current or future regulations could harm our business.

We are subject to federal, state, and local regulation of our business, both in the U.S. and internationally. In the U.S., both the FAA and the FCC regulate the construction, modification, and maintenance of towers and structures that support antennas used for wireless communications and radio and television broadcasts. In addition, the FCC separately licenses or otherwise regulates wireless communications equipment, wireless radio stations, and radio and television broadcast stations operating from such towers. FAA and FCC regulations govern construction, lighting, painting, and marking of towers and may, depending on the characteristics of the tower, require registration of the tower. Certain proposals to construct new towers, or to modify or add new equipment to existing towers, are reviewed by the FAA to ensure that the tower will not present a hazard to air navigation. Further, in connection with our previous acquisition of a building containing a data center, we also acquired a limited number of residential apartment units and became subject to additional federal, state, and local laws and regulations such as building, zoning, landlord/tenant, health and safety, and accessibility governing residential housing.

Tower owners may have an obligation to mark or paint such towers or install lighting to conform to FAA and FCC regulations and to maintain such marking, painting, and lighting. Tower owners may also bear the responsibility of notifying the FAA of any lighting outages. Certain proposals to operate wireless communications and radio or television broadcast stations from towers are also reviewed by the FCC to ensure compliance with environmental impact requirements established in federal statutes, including NEPA, NHPA, and ESA. Failure to comply with existing or future applicable requirements may lead to civil penalties or other liabilities and may subject us to significant indemnification liability to our customers against any such failure to comply. In addition, new regulations may impose additional costly burdens on us, which may affect our revenues and cause delays in our growth. Local regulations, including municipal or local ordinances, zoning restrictions, and restrictive covenants imposed by community developers, vary greatly, but typically require tower owners to obtain approval from local officials or community standards organizations prior to tower construction or modification. Local regulations can delay, prevent, or increase the cost of new construction, co-locations, or site upgrades, thereby limiting our ability to respond to customer demand. In addition, new regulations may be adopted that increase delays or result in additional costs to us. In our international operations, the impact of zoning, permitting, and related regulations and

16

Table of Contents

restrictive covenants on our new builds, co-locations, and operations could be exacerbated as some of these markets may lack established permitting processes for towers, have inconsistencies between national and local regulations, and have other barriers to timely construction and permitting of towers. As a result, tower construction in some of our international markets may be delayed or halted or our acquired towers may not perform as anticipated. These factors could have a material adverse effect on our future growth and operations.

Cybersecurity breaches and other disruptions could compromise our information, which would cause our business and reputation to suffer.

As part of our day-to-day operations, we rely on information technology and other computer resources and infrastructure to carry out important business activities and to maintain our business records. Our computer systems, or those of our cloud or Internet-based providers, could fail on their own accord and are subject to interruption or damage from power outages, computer and telecommunications failures, computer viruses, security breaches (including through cyber-attack, data theft, and exploiting potentially vulnerable services, such as virtual private networks and collaboration platforms as a result of remote working), errors, catastrophic events such as natural disasters, and other events beyond our control. If our or our vendors’ computer systems and backup systems are compromised, degraded, damaged, or breached, or otherwise cease to function properly, we could suffer interruptions in our operations or unintentionally allow misappropriation of proprietary or confidential information (including information about our tenants or landlords). This could damage our reputation and disrupt our operations and the services we provide to customers, which could adversely affect our business and operating results. In addition, security incidents that impact our customers and other business partners could adversely affect our business and operating results. Furthermore, our investments in ancillary services and emerging technologies, including data centers and our mobile edge computing initiative, may leave us more vulnerable to security incidents, create new exposure for us to different types of security incidents or exacerbate the impact of such incidents on our business and operating results.

Data privacy and protection laws are evolving globally and present risks related to our handling of sensitive data that could result in regulatory penalties or litigation.

A portion of the activities that support our business involve collection, storage, and transfer of sensitive data of our employees, tenants, ground lessors, and other third parties, including residential tenants as a result of our previous data center acquisition that included a limited number of residential apartment units. In recent years, there has been increased public attention regarding the protection of personal data and security of data transfers, accompanied by legislation and regulations intended to strengthen data protection and information security. The evolving nature of privacy laws in the U.S. and the other countries where we have operations could impact our compliance costs in handling such data. Many data privacy regulations also grant private rights of action, including Brazil's General Data Protection Law and certain state laws, such as California's Consumer Privacy Act. As interpretation and enforcement of these and other future data privacy regulations and industry standards evolve, we may incur costs related to litigation or regulatory penalties if we are alleged to be non-compliant.

Damage from natural disasters and other unforeseen events could adversely affect us.

Our towers are subject to physical climate-related risks and natural disasters (including as a result of any potential effects of climate change) such as tornadoes, fires, hurricanes, floods, and earthquakes or may collapse for any number of reasons, including structural deficiencies. In addition, we have energy sources on some of our tower sites, and any unforeseen incident may cause damage to surrounding property. We maintain insurance to cover the estimated cost of replacing damaged towers and damage to surrounding property, but these insurance policies are subject to loss limits, deductibles, and retentions. We also maintain third party liability insurance, subject to loss limits, deductibles, and retentions, to protect us in the event of an accident involving a tower. An incident involving our towers or tower sites for which we are uninsured or underinsured, or damage to a significant number of our towers or surrounding property, could require us to incur significant expenditures and may have a material adverse effect on our operations or financial condition and may harm our reputation.

To the extent that we are not able to meet our contractual obligations to our customers, due to a natural disaster or other catastrophic circumstances, our customers may not be obligated or willing to pay their lease expenses; however, we may be required to continue paying our fixed expenses related to the affected tower, including expenses for ground leases and other property interests. If we are unable to meet our contractual obligations to our customers for a material portion of our towers, our operations could be materially and adversely affected.

We could have liability under environmental laws that could have a material adverse effect on our business, financial condition and results of operations.

Our operations, like those of other companies engaged in similar businesses, are subject to the requirements of various federal, state, local, and foreign environmental and occupational safety and health laws and regulations (including climate-related laws and regulations), including those relating to the management, use, storage, disposal, emission and remediation of, and exposure to, hazardous and non-hazardous substances, materials, and wastes. As owner, lessee, or operator of numerous tower structures, we may be liable for substantial costs of remediating soil and groundwater contaminated by hazardous materials without regard to whether we, as the owner, lessee, or operator, knew of or were responsible for the contamination. We may be subject to potentially significant fines, penalties, or taxes if we fail to comply with any of these requirements. The current cost of complying with these laws is not material to our financial condition or results of operations. However, the requirements of these laws and regulations are complex, change frequently, and could become more stringent in the future. It is possible that these requirements will change or that liabilities will arise in the future in a manner that could have a material adverse effect on our business, financial condition, and results of operations.

We could suffer adverse tax and other financial consequences if taxing authorities do not agree with our tax positions.

We are periodically subject to a number of tax examinations by taxing authorities in the states and countries where we do business. We also have significant net operating losses (“NOLs”) in U.S. federal and state taxing jurisdictions. Generally, for U.S. federal and state tax purposes, NOLs generated prior to the 2018 tax year can be carried forward and used for up to 20 years, and all of our NOLs will remain subject to examination until three years after our NOLs are used or expire. NOLs generated starting in the 2018 tax year can be carried forward indefinitely but are subject to the 80% utilization limitation. We expect that we will continue to be subject to tax examinations in the future. In addition, U.S. federal, state, and local, as well as international, tax laws and regulations are extremely complex and subject to varying interpretations. If our tax benefits, including from our use of NOLs or other tax attributes, are challenged successfully by a taxing authority, we may be required to pay additional taxes or penalties, or make additional distributions, which could have a material adverse effect on our business, results of operations and financial condition.

We are subject to income tax and other taxes in the geographic areas where we hold assets or operate, and we periodically receive notifications of audits, assessments, or other actions by taxing authorities. In certain jurisdictions, taxing authorities may issue notices and assessments that may not be reflective of the actual tax liability for which we will ultimately be liable.

In connection with a current assessment in Brazil, the taxing authorities have issued income tax deficiencies related to purchase accounting adjustments for tax years 2016 through 2019. We disagree with the assessment and have filed an appeal with the higher appellate taxing authorities. We will continue to vigorously contest the adjustments and expect to exhaust all administrative and judicial remedies necessary to resolve the matters, which could be a lengthy process. There can be no assurance that these matters will be resolved in our favor, and an adverse outcome, or any future tax examinations involving similar assertions, could have a material effect on our results of operations or cash flows in any one period. As of December 31, 2023, we estimate the aggregate range of reasonably possible losses in excess of amounts accrued to be between zero and $97.8 million. This range excludes penalties and interest, which as of such date would have been $104.6 million.

Our issuance of equity securities and other associated transactions may trigger a future ownership change which may negatively impact our ability to utilize NOLs in the future.

The issuance of equity securities and other associated transactions may increase the chance that we will have a future ownership change under Section 382 of the Internal Revenue Code of 1986 (“Code”). We may also have a future ownership change, outside of our control, caused by future equity transactions by our current shareholders. Depending on our market value at the time of such future ownership change, an ownership change under Section 382 could negatively impact our ability to utilize our NOLs and could result in us having to make additional cash distributions.

Our costs could increase and our revenues could decrease due to perceived health risks from RF energy.

The U.S. and other foreign governments impose requirements and other guidelines relating to exposure to RF energy. Exposure to high levels of RF energy can cause negative health effects. The potential connection between exposure to low levels of RF energy and certain negative health effects, including some forms of cancer, has been the subject of substantial study by the scientific community in recent years. According to the FCC, the results of these studies to date have been inconclusive. However, public perception of possible health risks associated with cellular and other wireless communications technologies (such as 5G) could slow the growth of wireless companies and deployment of new technologies, which could in turn slow our growth. In particular, negative public perception of, and regulations regarding, health risks could cause a decrease in the demand for wireless

18

Table of Contents

communications services. Moreover, if a connection between exposure to low levels of RF energy and possible negative health effects, including cancer, were demonstrated, we could be subject to numerous claims. Our current policies provide no coverage for claims based on RF energy exposure. If we were subject to claims relating to exposure to RF energy, even if such claims were not ultimately found to have merit, our financial condition could be materially and adversely affected.

Risks Related to Our Status as a REIT

Complying with the REIT requirements may cause us to liquidate assets or hinder our ability to pursue otherwise attractive asset acquisition opportunities.

To qualify as a REIT for federal income tax purposes, we must continually satisfy tests concerning, among other things, the nature and diversification of our assets, the sources of our income and the amounts we distribute to our shareholders. For example, to qualify as a REIT, we must ensure that, at the end of each calendar quarter, at least 75% of the value of our assets consists of cash, cash items, government securities and “real estate assets” (as defined in the Code), including towers and certain mortgage loans and securities. The remainder of our investments (other than government securities, qualified real estate assets and securities issued by a taxable REIT subsidiary (“TRS”)) generally may not include more than 10% of the outstanding voting securities of any one issuer or more than 10% of the total value of the outstanding securities of any one issuer. In addition, in general, no more than 5% of the value of our total assets (other than government securities, qualified real estate assets, and securities issued by a TRS) may consist of the securities of any one issuer, and no more than 20% of the value of our total assets may be represented by securities of one or more TRSs. If we fail to comply with these requirements at the end of any calendar quarter, we must correct the failure within 30 days after the end of the calendar quarter or qualify for certain statutory relief provisions to avoid losing our REIT qualification and suffering adverse tax consequences. As a result, we may be required to liquidate assets in adverse market conditions or forgo otherwise attractive investments. These actions may reduce our income and amounts available for distributions to our shareholders.

In addition to the asset tests set forth above, to qualify and be subject to tax as a REIT, we will be required generally to distribute at least 90% of our REIT taxable income after the utilization of any available NOLs (determined without regard to the dividends paid deduction and excluding net capital gain) each year to our shareholders. Our determination as to the timing or amount of future dividends will be based on a number of factors, including investment opportunities around our core business and the availability of our existing NOLs. To the extent that we satisfy the 90% distribution requirement but distribute less than 100% of our REIT taxable income (after the application of available NOLs, if any), we will be subject to U.S. federal corporate income tax on our undistributed taxable income. In addition, we will be subject to a 4% nondeductible excise tax if the actual amount that we pay out to our shareholders for a calendar year is less than a minimum amount specified under the Code. These distribution requirements could hinder our ability to pursue otherwise attractive asset acquisition opportunities. Furthermore, our ability to compete for acquisition opportunities in domestic and international markets may be adversely affected if we need, or require, the target company to comply with certain REIT requirements. These actions could have the effect of reducing our income, amounts available for distribution to our shareholders, and amounts available for making payments on our indebtedness.

Qualifying as a REIT involves highly technical and complex provisions of the Code. If we fail to remain qualified as a REIT, to the extent we have REIT taxable income and have utilized our NOLs, we would lose the ability to deduct dividends paid to our shareholders in computing our taxable income, be subject to U.S. federal income tax as a regular corporation on such taxable income and could face a substantial tax liability, which would reduce the amount of cash available for distribution to our shareholders.

Qualification as a REIT involves the application of highly technical and complex Code provisions for which only limited judicial and administrative authorities exist. Even a technical or inadvertent violation could jeopardize our REIT qualification. Our qualification as a REIT will depend on our satisfaction of certain asset, income, organizational, distribution, shareholder ownership, and other requirements on a continuing basis. Our ability to satisfy the asset tests depends upon our analysis of the characterization and fair market values of our assets, some of which are not susceptible to a precise determination, and for which we will not obtain independent appraisals.

If we fail to qualify as a REIT in any taxable year, to the extent we have REIT taxable income and have utilized our NOLs, we would be subject to U.S. federal income tax on our taxable income at regular corporate rates, and dividends paid to our shareholders would not be deductible by us in computing our taxable income. Any resulting corporate tax liability could be substantial and would reduce the amount of cash available for distribution to our shareholders, which in turn could have an adverse impact on the value of our common stock. Unless we were entitled to relief under certain provisions of the Code, we also would be disqualified from re-electing to be taxed as a REIT for the four taxable years following the year in which we failed to qualify as a REIT. If we fail to qualify for taxation as a REIT, we may need to borrow additional funds or liquidate assets to pay any additional tax liability. Accordingly, funds available for investment and making payments on our indebtedness would be reduced.

We may be required to borrow funds, sell assets, or raise equity to satisfy our REIT distribution requirements.

From time to time, we may generate REIT taxable income greater than our cash flow as a result of differences in timing between the recognition of taxable income and the actual receipt of cash or the effect of nondeductible capital expenditures, the creation of reserves or required debt or amortization payments. If we do not have other funds available in these situations, we may need to borrow funds, sell assets or raise equity, even if the then-prevailing market conditions are not favorable for these borrowings, sales, or offerings, to enable us to satisfy the REIT distribution requirement and to avoid U.S. federal corporate income tax and the 4% excise tax in a particular year. These alternatives could increase our costs and our leverage, decrease our Adjusted Funds From Operations, or require us to distribute amounts that would otherwise be invested in future acquisitions or stock repurchases.

Thus, compliance with the REIT requirements may hinder our ability to grow, which could adversely affect the value of our common stock. Furthermore, compliance with the REIT distribution requirements may increase the financing we need to fund capital expenditures, future growth, or expansion initiatives, which would increase our total leverage.

Covenants specified in our current and future debt instruments may limit our ability to make required REIT distributions.

The mortgage loan agreement related to our securitization transactions, the Senior Credit Agreement, and the indentures governing our 2020 Senior Notes and 2021 Senior Notes contain certain covenants that could limit our ability to make distributions to our shareholders. Under the mortgage loan agreement related to our securitization transactions, a failure to comply with the Debt Service Coverage Ratio in that agreement could prevent our borrower subsidiaries from distributing any excess cash from the operation of their towers to us. In addition, while the Senior Credit Agreement permits our subsidiaries to make distributions to us to satisfy our REIT distribution requirements, this authority is subject to condition that our subsidiaries are not then in default of their payment obligations under the Senior Credit Agreement or that we or any of our subsidiaries have filed an action relating to bankruptcy, insolvency, reorganization or relief of debtors. Furthermore, while the indentures governing the 2020 Senior Notes and 2021 Senior Notes permit us to make distributions to our shareholders to the extent such distributions are necessary to maintain our status as a REIT or to avoid entity level taxation, this authority is subject to the conditions that no default or event of default exists or would result therefrom and that the obligations under the 2020 Senior Notes or 2021 Senior Notes, as applicable, have not otherwise been accelerated.

If these limitations prevent us from satisfying our REIT distribution requirements, we could fail to qualify for taxation as a REIT. If these limitations do not jeopardize our qualification for taxation as a REIT but do nevertheless prevent us from distributing 100% of our REIT taxable income, we will be subject to U.S. federal corporate income tax, and potentially the nondeductible 4% excise tax, on the retained amounts.

Our payment of cash distributions in the future is not guaranteed and the amount of any future cash distributions may fluctuate, which could adversely affect the value of our Class A common stock.

REITs are required to distribute annually at least 90% of their REIT taxable income (determined before the deduction for dividends paid and excluding any net capital gain). We may use our NOLs to offset our REIT taxable income, and thus any required distributions to shareholders may be reduced or eliminated until such time as the NOLs have been fully utilized, which may adversely affect the market value of our Class A common stock. The Code places limitations upon the future availability of NOLs based upon changes in our equity. If these occur, our ability to offset future income with existing NOLs may be limited.

The amount of future distributions will be determined, from time to time, by our Board of Directors to balance our goal of increasing long-term shareholder value and retaining sufficient cash to implement our current capital allocation policy, which prioritizes investment in quality assets that meet our return criteria, and then stock repurchases, when we believe our stock price is below its intrinsic value. The actual timing and amount of distributions will be as determined and declared by our Board of Directors and will depend on, among other factors, our NOLs, our financial condition, earnings, debt covenants, and other possible uses of such funds. Consequently, our future distribution levels may fluctuate.

Certain of our business activities may be subject to corporate level income tax and foreign taxes, which would reduce our cash flows, and would have potential deferred and contingent tax liabilities.

We may be subject to certain federal, state, local, and foreign taxes on our income and assets, including alternative minimum taxes, taxes on any undistributed income, and state, local, or foreign income, franchise, property, and transfer taxes. In addition, we could be required, in certain circumstances, to pay an excise or penalty tax, which could be significant in amount, in order to utilize one or more relief provisions under the Code to maintain qualification for taxation as a REIT. In addition, we may incur a 100%

20

Table of Contents

excise tax on transactions with a TRS if they are not conducted on an arm’s length basis. Any of these taxes would decrease our earnings and our available cash.

Our TRS assets and operations also will continue to be subject, as applicable, to federal and state corporate income taxes and to foreign taxes in the jurisdictions in which those assets and operations are located. Any of these taxes would decrease our earnings and our available cash.

Our use of TRSs may cause us to fail to qualify as a REIT.

The net income of our TRSs is not required to be distributed to us, and such undistributed TRS income is generally not subject to our REIT distribution requirements. However, if the accumulation of cash or reinvestment of significant earnings in our TRSs causes the fair market value of our securities in those entities, taken together with other non-qualifying assets, to represent more than 20% of the value of our total assets, in each case, as determined for REIT asset testing purposes, we would, absent timely responsive action, fail to qualify as a REIT. If we continue our international expansion, our TRS fair market value may cause us to exceed the above thresholds.

Legislative or other actions affecting REITs could have a negative effect on us.

The rules dealing with U.S. federal income taxation are constantly under review by persons involved in the legislative process and by the IRS and the Treasury. Changes to the tax laws or interpretations thereof, with or without retroactive application, could materially and adversely affect our investors or us. We cannot predict how changes in the tax laws might affect our investors or us. New legislation, U.S. Treasury Regulations, administrative interpretations, or court decisions could affect significantly and negatively our ability to qualify as a REIT or the U.S. federal income tax consequences to our investors and us of such qualification.

Our Board’s ability to revoke our REIT qualification, without shareholder approval, may cause adverse consequences to our shareholders.

Our articles of incorporation provide that our Board of Directors may revoke or otherwise terminate our REIT election, without the approval of our shareholders, if it determines that it is no longer in our best interests to continue to qualify as a REIT. If we cease to be a REIT, we will not be allowed a deduction for dividends paid to shareholders, if any, in computing our taxable income, and to the extent we have taxable income and have utilized our NOLs, we will be subject to U.S. federal income tax at regular corporate rates and state and local taxes, which may have adverse consequences on our total return to our shareholders.

We began operating as a REIT in 2016, which may adversely affect our financial condition, results of operations, cash flow, per share trading price of our common stock and ability to satisfy debt service obligations.

We began operating as a REIT in 2016 and may not be able to continue to operate successfully as a REIT. In addition, we are required to maintain substantial control systems and procedures in order to maintain our status as a REIT. We have also incurred additional legal, accounting, and other expenses that we did not incur prior to operating as a REIT and our management and other personnel have devoted additional time to comply with these rules and regulations and controls required for continued compliance with the Code. These factors may adversely affect our performance as a REIT. If our performance is adversely affected, it could affect our financial condition, results of operations, cash flow, and ability to satisfy our debt service obligations.

Dividends payable by REITs generally do not qualify for the reduced tax rates available for some dividends.

The maximum U.S. federal income tax rate applicable to income from “qualified dividends” payable to U.S. shareholders that are individuals, trusts, and estates is currently 20%. Dividends payable by REITs, however, generally are not eligible for the reduced rates applicable to qualified dividends and instead generally are taxable at ordinary income rates. Although these rules do not adversely affect the taxation of REITs, the more favorable rates applicable to qualified dividends could cause investors who are individuals, trusts, and estates to perceive investments in REITs to be relatively less attractive than investments in the stocks of non-REIT corporations that pay dividends, which could adversely affect the value of the stock of REITs, including our common stock. However, for taxable years beginning before 2026, our non-corporate U.S. shareholders generally may deduct up to 20% of dividends paid by us, other than capital gain dividends and dividends treated as “qualified dividends.” Without further legislative action, this 20% deduction will expire on January 1, 2026.

Risks Related to Ownership of our Class A Common Stock

The REIT-related ownership and transfer restrictions may restrict or prevent our shareholders from engaging in certain transfers of our common stock.

In order for us to satisfy the requirements for REIT qualification, no more than 50% in value of all classes or series of our outstanding shares of stock may be owned, beneficially or constructively, by 5 or fewer individuals (as defined in the Code to include certain entities) at any time during the last half of each taxable year (other than the first year for which an election to be subject to tax as a REIT has been made). In addition, our capital stock must be beneficially owned by 100 or more persons during at least 335 days of a taxable year of 12 months or during a proportionate part of a shorter taxable year (other than the first year for which an election to be taxed as a REIT has been made). Our articles of incorporation contain REIT-related ownership and transfer restrictions that generally restrict shareholders from owning more than 9.8%, by value or number of shares, whichever is more restrictive, of our outstanding shares of Class A common stock, or 9.8% in aggregate value of the outstanding shares of all classes and series of our capital stock. Under applicable constructive ownership rules, any shares of stock owned by certain affiliated owners generally would be added together for purposes of the ownership limits. These ownership and transfer restrictions could have the effect of delaying, deferring, or preventing a transaction or a change in control that might involve a premium price for our capital stock or otherwise be in the best interest of our shareholders.

Our articles of incorporation, our bylaws and Florida law provide for anti-takeover provisions that could make it more difficult for a third party to acquire us.

Provisions of our articles of incorporation, our bylaws and Florida law could make it more difficult for a third party to acquire us, even if doing so would be beneficial to our shareholders. These provisions, alone or in combination with each other, may discourage transactions involving actual or potential changes of control, including transactions that otherwise could involve payment of a premium over prevailing market prices to holders of our Class A common stock, or could limit the ability of our shareholders to approve transactions that they may deem to be in their best interests.

ITEM 1C. CYBERSECURITY

Risk Management & Strategy

A cybersecurity threat is any potential unauthorized occurrence, on or conducted through, our information systems that may result in adverse effects on the confidentiality, integrity or availability of our information systems or any information residing therein. We have a comprehensive, cross-functional approach to cybersecurity risk management, driven by our information security management systems and propelled by industry-leading expertise from both our internal information technology security team and top-tier third-party consultants and firms that we engage. Our cyber risk management process is supported by both management and our Board of Directors.

Our cybersecurity risk management strategies represent an integral component of our overall approach to enterprise risk management (“ERM”). Our cybersecurity policies, standards, processes, and practices are fully integrated into our ERM program and based on the recognized National Institute of Standards and Technology (NIST) Cybersecurity Framework. We continuously seek to adopt market-leading standards and procedures to protect our tower infrastructure, data, and carrier and consumer information. Key elements of our cybersecurity risk management strategy include:

(1)System Monitoring and Testing. We work collaboratively with third-party industry experts and consultants to conduct regular vulnerability assessments and penetration testing from both outside and within our system networks. Our information security team utilizes endpoint software together with technology platforms and applications designed to enable it to monitor user and network behavior and origination points in real time both at our corporate headquarters as well as any of our sites globally. In addition, we conduct quarterly phishing campaign simulations which include notification of the respective Executive Vice President in the event of a failure by an employee in their department.

(2)Threat Identification & Response. Our internal information security team works collaboratively with our external industry consultants to identify threats utilizing analytics and metrics, which are aligned with the MITRE ATT&CK (Adversarial Tactics, Techniques, and Common Knowledge) Framework, and mitigate attacks across various layers of our enterprise systems. We

22

Table of Contents

leverage the core functions of the NIST Cybersecurity Framework (Identify, Protect, Detect, Respond, and Recover) to constantly work toward identifying opportunities for further improvement and development of our risk mitigation strategies. We also build upon the principles of the ISO 27001 standard and have achieved ISO 27001:2013 certification for one of our data centers. As part of our response preparedness, our executive management team participates in comprehensive tabletop exercises annually simulating cybersecurity breaches or other incidents which simulate identifying, responding and reporting of such an incident in accordance with our risk management programs.

(3)Defense Procedures & Preparedness. We have established and maintain a data incident response and a business continuity management plan to timely, consistently, and appropriately address cyber threats that may occur despite our safeguards. The response plan is global in scope and covers the major phases of the incident response process, including preparation, detection and analysis, containment and investigation, notification (which may include timely notice to our Board if deemed material or appropriate), eradication and recovery, and incident closure and post-incident analysis. Our response plan is reviewed annually, regularly tested, and updated based on developments in the industry. Our business continuity management system includes targets and objectives, impact analyses and risk assessments, exercise and testing, training and awareness, documentation and standards for data centers and servers.

(4)Outside Consultants & Industry Experts. In addition to the broad capabilities of our internal information security team, we also engage various outside consultants, including contractors, security firms, auditors, and other third-party subject matter experts, to among other things, conduct regular testing of our networks and systems to identify vulnerabilities through penetration testing, while also measuring and advising on potential improvements to our cybersecurity programs. We are also members of recognized global industry organizations such as the Information Systems Audit and Control Association (ISACA), International Information System Security Certification Consortium (ISC), and International Association of Privacy Professionals (IAPP).

(5)Third-Party Risk Assessments. We maintain a comprehensive risk-based approach to identifying and overseeing potential cybersecurity risks presented by third parties, including our vendors and service providers. We have a dedicated information technology vendor management team that reports to our Chief Information Officer (“CIO”). We conduct initial and regular cybersecurity assessments of third-party vendors that we engage with in our operations and their information security policies and systems in order to identify, evaluate, and address potential vulnerabilities.

(6)Team Member Education & Awareness. We remain dedicated to fostering an internal culture of cybersecurity, where all of our team members are trained to identify, respond, and report potential cybersecurity threats that may arise. New hires are required to participate in cybersecurity onboarding training, and current employees are responsible for completing mandatory cybersecurity training annually and phishing awareness training quarterly. Our leadership team participates in advanced, targeted cybersecurity training and exercises to ensure additional security.

As part of our cybersecurity risk management strategy, each cyber threat is evaluated for materiality and escalated based upon evaluation of the potential severity and risk impact on our operations. We have not experienced a material cybersecurity breach in the past three years. As such, we have not incurred any material expenses from cybersecurity breaches or any expenses from penalties or settlements related to a cybersecurity breach during that time. For more information regarding cybersecurity-related risks that could materially affect our business strategies, results of operations, or financial condition, please see Item 1A in this Form 10-K under the headings “Security breaches and other disruptions could compromise our information, which would cause our business and reputation to suffer.”

Governance & Personnel

Our Board believes a robust cybersecurity strategy is vital to protect our business, customers, and assets. The Board has delegated to the Audit Committee responsibility for oversight and review of our cybersecurity and other information technology and data privacy risk management program, controls, strategies, and procedures. The Audit Committee periodically evaluates our cybersecurity strategies to ensure effectiveness and, if appropriate, includes a review from third-party experts. In addition, our Board also may review and assess cybersecurity risks as part of its responsibilities for general risk oversight.

Our CIO reports to the Audit Committee at every regularly scheduled meeting (or more frequently, as needed) to discuss cybersecurity risk exposure and risk management strategy. Our CIO has over 25 years of experience in the information technology and security industry with global organizations. Our executive leadership team, which includes our CIO, reviews and manages implementation of our cybersecurity strategy and programs through regularly scheduled meetings.

Our information security team, led by our CIO and Senior Director, IT Security and Compliance, has over 75 years of collective cybersecurity experience and maintain numerous active industry-recognized cyber certifications, such as Certified Information Security Manager (CISM), Certified Information Systems Security Professional (CISSP), and Certified Information Systems Auditor (CISA). Our information security team undertakes a variety of measures in the daily monitoring and management of cybersecurity risks across our business. For example, the information security team monitors our technology infrastructure with tools

23

Table of Contents

designed to detect suspicious behavior and decrypt VPN traffic on our systems globally. The information security team conducts regular internal and external audits with third-party cybersecurity experts to identify and evaluate potential weaknesses in its cybersecurity systems. Some of these third-party monitoring functions continue throughout the year while other third-party security experts are periodically retained to audit specific areas of our cybersecurity program. In addition, our information security team works with our internal audit function to monitor reporting and escalation of cybersecurity incident reports from across our business.

ITEM 2. PROPERTIES

We own our headquarters in Boca Raton, Florida where we currently have approximately 160,000 square feet of office space. We also own or have entered into long-term leases for international and regional locations convenient for the management and operation of our site leasing activities, and in certain site development office locations where we expect our activities to be longer-term. We believe our existing facilities are adequate for our current and planned levels of operations and that additional office space suited for our needs is reasonably available in the markets within which we operate.

Our interests in towers and the land beneath them are comprised of a variety of fee interests, leasehold interests created by long-term lease agreements, perpetual easements, easements, licenses, rights-of-way, right-of-use, and other similar interests. As of December 31, 2023, approximately 71% of our tower structures were located on parcels of land that we own, land subject to perpetual easements, or parcels of land that have an interest that extends beyond 20 years. The average remaining life under our ground leases and other property interests, including renewal options under our control, is 36 years. In rural areas, support for our towers, equipment shelters, and related equipment requires a tract of land typically up to 10,000 square feet. Less than 2,500 square feet is required for a monopole or self-supporting tower of the kind typically used in metropolitan areas for wireless communications towers. Ground leases and other property interests are generally for an initial term of five years or more with multiple renewal periods, for a total of 30 years or more.

Most of our towers have significant capacity available for additional antennas. We measure the available capacity of our existing facilities to support additional tenants and generate additional lease revenue by assessing several factors, including tower height, tower type, wind loading, environmental conditions, existing equipment on the tower and zoning and permitting regulations in effect in the jurisdiction where the tower is located. As of December 31, 2023, we had an average of 1.9 tenants per tower.

ITEM 3. LEGAL PROCEEDINGS

We are involved in various legal proceedings relating to claims arising in the ordinary course of business. We do not believe that the ultimate resolution of these matters will have a material adverse effect on our business, financial condition, results of operations, or liquidity.

ITEM 4. MINE SAFETY DISCLOSURE

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Market for our Class A Common Stock

Our Class A common stock commenced trading under the symbol “SBAC” on The NASDAQ National Market System on June 16, 1999. We now trade on the NASDAQ Global Select Market, a segment of the NASDAQ Global Market, formally known as the NASDAQ National Market System.

As of February 15, 2024, there were 283 record holders of our Class A common stock.

Dividends

As a REIT, we are required to distribute annually at least 90% of our REIT taxable income after the utilization of any available NOLs (determined before the deduction for dividends paid and excluding any net capital gain). As of December 31, 2023, $382.3 million of the federal NOLs are attributes of the REIT. We may use these NOLs to offset our REIT taxable income, and thus

24

Table of Contents

any required distributions to shareholders may be reduced or eliminated until such time as our NOLs have been fully utilized. The amount of future distributions will be determined, from time to time, by our Board of Directors to balance our goal of increasing long-term shareholder value and retaining sufficient cash to implement our current capital allocation policy, which prioritizes investment in quality assets that meet our return criteria, and then stock repurchases when we believe our stock price is below its intrinsic value. The actual amount, timing, and frequency of future dividends, will be at the sole discretion of our Board of Directors and will be declared based upon various factors, many of which are beyond our control.

ITEM 6. RES ERVED

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of our financial condition and results of operations should be read in conjunction with the information contained in our consolidated financial statements and the notes thereto. The following discussion includes forward-looking statements that involve certain risks and uncertainties, including, but not limited to, those described in Item 1A. Risk Factors. Our actual results may differ materially from those discussed below. See “Special Note Regarding Forward-Looking Statements” and Item 1A. Risk Factors.

We are a leading independent owner and operator of wireless communications infrastructure, including tower structures, rooftops, and other structures that support antennas used for wireless communications, which we collectively refer to as “towers” or “sites.” Our principal operations are in the United States and its territories. In addition, we own and operate towers in South America, Central America, Canada, South Africa, the Philippines, and Tanzania. Our primary business line is our site leasing business, which contributed 97.4% of our total segment operating profit for the year ended December 31, 2023. In our site leasing business, we (1) lease space to wireless service providers and other customers on assets that we own or operate and (2) manage rooftop and tower sites for property owners under various contractual arrangements. As of December 31, 2023, we owned 39,618 towers, a substantial portion of which have been built by us or built by other tower owners or operators who, like us, have built such towers to lease space to multiple wireless service providers. Our other business line is our site development business, through which we assist wireless service providers in developing and maintaining their own wireless service networks.

Site Leasing

Our primary focus is the leasing of antenna space on our multi-tenant towers to a variety of wireless service providers under long-term lease contracts in the United States, South America, Central America, Canada, South Africa, the Philippines, and Tanzania. As of December 31, 2023, no U.S. state or territory accounted for more than 10% of our total tower portfolio by tower count, and no U.S. state or territory accounted for more than 10% of our total revenues for the year ended December 31, 2023. In addition, as of December 31, 2023, approximately 30% of our total towers are located in Brazil and no other international market (each country is considered a market) represented more than 5% of our total towers.

25

Table of Contents

We derive site leasing revenues from all the major carriers in each of the 15 countries in which we operate. Our tenant leases are either (1) individual tenant site leases by tower site or (2) governed by master lease agreements which provide for the material terms and conditions that will apply to multiple sites; although, in most cases, each individual site under a master lease agreement is also governed by its own site leasing agreement which sets forth pricing and other site specific terms. Our tenant leases are generally for an initial term of five years to fifteen years with multiple renewal periods at the option of the tenant. Our tenant leases typically either (1) contain specific annual rent escalators, (2) escalate annually in accordance with an inflationary index, or (3) escalate using a combination of fixed and inflation adjusted escalators. In addition, our international site leases may include pass-through charges, such as rent related to ground leases and other property interests, utilities, property taxes, and fuel.

Cost of site leasing revenue primarily consists of:

•Cash and non-cash rental expense on ground leases, right-of-use, and other underlying property interests;

•Property taxes;

•Site maintenance and monitoring costs (exclusive of employee related costs);

•Utilities;

•Property insurance;

•Fuel (in those international markets that do not have an available electric grid at our tower sites); and

•Lease initial direct cost amortization.

Ground leases and other property interests are generally for an initial term of five years or more with multiple renewal periods, which are at our option. Our ground leases typically either (1) contain specific annual rent escalators or (2) escalate annually in accordance with an inflationary index. As of December 31, 2023, approximately 71% of our tower structures were located on parcels of land that we own, land subject to perpetual easements, or parcels of land in which we have a leasehold interest that extends beyond 20 years. For any given tower, costs are relatively fixed over a monthly or an annual time period. As such, operating costs for owned towers do not generally increase as a result of adding additional customers to the tower. The amount of property taxes varies from site to site depending on the taxing jurisdiction and the height and age of the tower. The ongoing maintenance requirements are typically minimal and include replacing lighting systems, painting a tower, or upgrading or repairing an access road or fencing.

In Ecuador, El Salvador, Guatemala, Nicaragua, and Panama, significantly all of our revenue, expenses, and capital expenditures arising from our activities are denominated in U.S. dollars. Specifically, most of our ground leases and other property interests, tenant leases, and tower-related expenses are paid in U.S. dollars. In our Central American markets, our local currency obligations are principally limited to (1) permitting and other local fees, (2) utilities, and (3) taxes. In Brazil, Canada, Chile, South Africa, and the Philippines, significantly all of our revenue, expenses, and capital expenditures, including tenant leases, ground leases and other property interests, and other tower-related expenses are denominated in local currency. In Colombia, Costa Rica, Peru, and Tanzania, our revenue, expenses, and capital expenditures, including tenant leases, ground leases and other property interests, and other tower-related expenses are denominated in a mix of local currency and U.S. dollars.

As indicated in the table below, our site leasing business generates substantially all of our total segment operating profit. For information regarding our operating segments, see Note 15 of our Consolidated Financial Statements included in this annual report.

|  | For the year ended
Segment operating profit as a percentage of |  | December 31,
total operating profit |  | 2023 |  | 2022 |  | 2021
Domestic site leasing |  |  | 75.2% |  |  | 77.0% |  |  | 80.7%
International site leasing |  |  | 22.2% |  |  | 19.2% |  |  | 16.7%
Total site leasing |  |  | 97.4% |  |  | 96.2% |  |  | 97.4%

We believe that the site leasing business continues to be attractive due to its long-term contracts, built-in rent escalators, high operating margins, and low customer churn (which refers to a lease that is non-renewed, cancelled, or discounted prior to the end of its term) other than in connection with customer consolidation or cessations of specific technology. We believe that over the long-term, site leasing revenues will continue to grow as wireless service providers lease additional antenna space on our towers due to increasing minutes of network use and data transfer, network expansion, and network coverage requirements.

During 2024, we expect organic site leasing revenue in both our domestic and international segments to increase over 2023 levels due in part to wireless carriers deploying unused spectrum. We believe our site leasing business is characterized by stable and long-term recurring revenues, predictable operating costs, and minimal non-discretionary capital expenditures. Due to the relatively young age and mix of our tower portfolio, we expect future expenditures required to maintain these towers to be minimal. Consequently, we expect to grow our cash flows by (1) adding tenants to our towers at minimal incremental costs by using existing tower capacity or requiring wireless service providers to bear all or a portion of the cost of tower modifications and (2) executing monetary amendments as wireless service providers add or upgrade their equipment. Furthermore, because our towers are strategically

positioned, we have historically experienced low tenant lease terminations as a percentage of revenue other than in connection with customer consolidation or cessations of a specific technology.

During 2020, the consolidation of T-Mobile and Sprint was completed, and we began to experience non-renewal of certain leases as a result of this merger. We currently expect that this churn will represent an aggregate of between $125.0 million and $150.0 million of cash site leasing revenue from 2024 through 2028. The aggregate churn estimate includes both overlapping and adjacent Sprint leases.

Site Development

Our site development business, which is conducted in the United States only, is complementary to our site leasing business and provides us the ability to keep in close contact with the wireless service providers who generate substantially all of our site leasing revenue and to capture ancillary revenues that are generated by our site leasing activities, such as antenna and equipment installation at our tower locations. Site development revenues are earned primarily from providing a full range of end-to-end services to wireless service providers or companies providing development or project management services to wireless service providers. Our services include: (1) network pre-design; (2) site audits; (3) identification of potential locations for towers and antennas on existing infrastructure; (4) support in leasing of the location; (5) assistance in obtaining zoning approvals and permits; (6) tower and related site construction; (7) antenna installation; and (8) radio equipment installation, commissioning, and maintenance. We provide site development services at our towers and at towers owned by others on a local basis, through regional, market, and project offices. The market offices are responsible for all site development operations.

For information regarding our operating segments, see Note 15 of our Consolidated Financial Statements included in this annual report.

Capital Allocation Strategy

Our capital allocation strategy is aimed at increasing shareholder value through investment in quality assets that meet our return criteria, stock repurchases when we believe our stock price is below its intrinsic value, and by returning cash generated by our operations in the form of cash dividends. While the addition of a cash dividend to our capital allocation strategy has provided us with an additional tool to return value to our shareholders, we continue to believe that our priority is to make investments focused on increasing Adjusted Funds From Operations per share. Key elements of our capital allocation strategy include:

Portfolio Growth. We intend to continue to grow our asset portfolio, domestically and internationally, primarily through tower acquisitions and the construction of new towers that meet our internal return on invested capital criteria.

Stock Repurchase Program. We currently utilize stock repurchases as part of our capital allocation policy when we believe our share price is below its intrinsic value. We believe that share repurchases, when purchased at the right price, will facilitate our goal of increasing our Adjusted Funds From Operations per share.

Dividend. Cash dividends are an additional component of our strategy of returning value to shareholders. We do not expect our dividend to require any changes in our leverage and believe that, due to our low dividend payout ratio, we can continue to focus on building and buying quality assets and opportunistically buying back our stock. While the timing and amount of future dividends will be subject to approval by our Board of Directors, we believe that our future cash flow generation will permit us to grow our cash dividend in the future.

Critical Accounting Policies and Estimates

We have identified the policies and significant estimation processes below as critical to our business operations and the understanding of our results of operations. The listing is not intended to be a comprehensive list. In many cases, the accounting treatment of a particular transaction is specifically dictated by accounting principles generally accepted in the United States, with no need for management’s judgment in their application. In other cases, management is required to exercise judgment in the application of accounting principles with respect to particular transactions. The impact and any associated risks related to these policies on our business operations is discussed throughout “Management’s Discussion and Analysis of Financial Condition and Results of Operations” where such policies affect reported and expected financial results. For a detailed discussion on the application of these and other accounting policies, see Note 2 of our Consolidated Financial Statements for the year ended December 31, 2023, included herein. Our preparation of our financial statements requires us to make estimates and assumptions that affect the reported amount of assets and liabilities, disclosure of contingent assets and liabilities at the date of our financial statements, and the reported amounts of revenue and expenses during the reporting periods. Management bases its estimates on historical experience and on various other

27

Table of Contents

assumptions that are believed to be reasonable under the circumstances. There can be no assurance that actual results will not differ from those estimates and such differences could be significant.

Our significant accounting policies are described in Note 2 of our Consolidated Financial Statements included in this annual report. There have been no material changes to our significant accounting policies during the year ended December 31, 2023. We are in the process of reviewing the remaining estimated useful lives of our towers and intangible assets and are considering, for U.S. GAAP purposes, whether we should modify our current estimates for asset lives based on our historical operating experience. We have retained an independent consultant to assist in completing this review and analysis. We currently depreciate our towers on a straight-line basis over the shorter of the term of the underlying ground lease (including renewal options) taking into account residual value or the estimated useful life of the tower, which we have historically estimated to be 15 years. Additionally, certain of our intangible assets are amortized on a similar basis to our tower assets, as the estimated useful lives of such intangible assets correlate to the useful life of the towers. If we conclude that a revision in the estimated useful lives of our towers and intangible assets is appropriate based on our review and analysis, we will account for any changes in the useful lives as a change in accounting estimate under ASC 250 Accounting Changes and Error Corrections, which will be recorded prospectively beginning in the period of change. Based on preliminary information obtained to date, we expect that our estimated asset lives may be extended, which would result in prospective (i) decreases in depreciation and amortization and (ii) increases in the right of use asset and operating lease liability, and such changes could be material to future depreciation and amortization and our consolidated results of operations. We expect to conclude our analysis in the first quarter of 2024.

Revenue Recognition and Accounts Receivable

Site leasing revenues

Revenue from site leasing is recognized on a straight-line basis over the current term of the related lease agreements, which are generally five years to fifteen years. Receivables recorded related to the straight-lining of site leases are reflected in other assets on the Consolidated Balance Sheets. Rental amounts received in advance are recorded as deferred revenue on the Consolidated Balance Sheets. Revenue from site leasing represents 93% of our total revenue for the year ended December 31, 2023.

Site development revenues

Site development projects in which we perform consulting services include contracts on a fixed price basis that are billed at contractual rates. Revenue is recognized over time based on milestones achieved, which are determined based on costs incurred. Amounts billed in advance (collected or uncollected) are recorded as deferred revenue on our Consolidated Balance Sheets.

Revenue from construction projects is recognized over time, determined by the percentage of cost incurred to date compared to management’s estimated total cost for each contract. This method is used because management considers total cost to be the best available measure of progress on the contracts. These amounts are based on estimates, and the uncertainty inherent in the estimates initially is reduced as work on the contracts nears completion. Refer to Note 5 in our Consolidated Financial Statements included in this annual report for further detail of costs and estimated earnings in excess of billings on uncompleted contracts. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined to be probable.

The site development segment represents approximately 7% of our total revenues for the year ended December 31, 2023. We account for site development revenue in accordance with ASC 606, Revenue from Contracts with Customers. Payment terms do not result in any significant financing arrangements. Furthermore, these contracts do not typically include variable consideration; therefore, the transaction price that is recognized over time is generally the amount of the total contract.

Accounts receivable

The accounts receivable balance for the years ended December 31, 2023 and 2022 was $182.7 million and $184.4 million, respectively, of which $32.3 million and $59.6 million related to the site development segment, respectively. We perform periodic credit evaluations of our customers. In addition, we monitor collections and payments from our customers and maintain a provision for estimated credit losses based upon historical experience, specific customer collection issues identified, and past due balances as determined based on contractual terms. Interest is charged on outstanding receivables from customers on a case by case basis in accordance with the terms of the respective contracts or agreements with those customers. Amounts determined to be uncollectible are written off against the allowance for doubtful accounts in the period in which uncollectibility is determined to be probable. Refer to Note 15 in our Consolidated Financial Statements included in this annual report for further detail of the site development segment.

Lease Accounting

ASU No. 2016-02, Leases (“Topic 842”) requires all lessees to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments. We have elected not to separate nonlease components from the associated lease component for all underlying classes of assets. In order to calculate our lease liability, we make certain assumptions related to lease term and discount rate. To determine the lease term, we consider all renewal periods that are reasonably certain to be exercised, taking into consideration all economic factors, including the communications site’s estimated economic life and the respective lease terms of our tenants under the existing lease arrangements on such site. For the discount rate, we use the rate implicit in the lease when available to discount lease payments to present value. However, our ground leases and other property interests generally do not provide a readily determinable implicit rate. Therefore, we estimate the incremental borrowing rate to discount lease payments based on the lease term and lease currency. We use publicly available data for instruments with similar characteristics when calculating our incremental borrowing rates. Refer to Note 2 in our Consolidated Financial Statements included in this annual report for further discussion on lease accounting.

Reference Rate Reform

On June 21, 2023, we amended our interest rate swap to change from LIBOR as an interest rate benchmark to the replacement benchmark of Term SOFR effective on August 1, 2023. We have elected the optional expedient which allows companies to change the reference rate and other critical terms related to the reference rate reform in derivative hedge documentation without having to de-designate the hedging relationship, allowing us to continue applying hedge accounting to our cash flow hedge. On July 3, 2023, we amended our 2018 Term Loan and our Revolving Credit Facility to use Term SOFR as the benchmark rate. The transition from LIBOR to Term SOFR did not have a material impact on the consolidated financial statements. Refer to “Debt Instruments and Debt Service Requirements” below for further discussion of the 2018 Term Loan, Revolving Credit Facility, and the interest rate swap.

RESULTS OF OPERATIONS

This report presents our financial results and other financial metrics on a GAAP basis and, with respect to our international and consolidated results, after eliminating the impact of changes in foreign currency exchange rates. We believe that providing these financial results and metrics on a constant currency basis, which are non-GAAP measures, gives management and investors the ability to evaluate the performance of our business without the impact of foreign currency exchange rate fluctuations. We eliminate the impact of changes in foreign currency exchange rates by dividing the current period’s financial results by the average monthly exchange rates of the prior year period, as well as by eliminating the impact of realized and unrealized gains and losses on our intercompany loans.

Revenues

Domestic site leasing revenues increased $69.0 million for the year ended December 31, 2023, as compared to the prior year, primarily due to (1) organic site leasing growth, primarily from monetary lease amendments (due in part to the new MLA with AT&T) for additional equipment added to our towers as well as new leases and contractual rent escalators and (2) revenues from 135 towers acquired and 22 towers built since January 1, 2022, partially offset by lease non-renewals.

International site leasing revenues increased $111.4 million for the year ended December 31, 2023, as compared to the prior year. On a constant currency basis, international site leasing revenues increased $109.4 million. These changes were primarily due to (1) revenues from 3,301 towers acquired (including 2,632 sites from GTS in Brazil) and 779 towers built since January 1, 2022, (2) an increase in reimbursable pass-through expenses due primarily to increases in consumer price index escalators on our ground leases, and (3) organic site leasing growth from new leases, amendments, and contractual escalators, partially offset by lease non-renewals. Site leasing revenue in Brazil represented 15.6% of total site leasing revenue for the period. No other individual international market represented more than 5% of our total site leasing revenue.

Site development revenues decreased $102.2 million for the year ended December 31, 2023, as compared to the prior year, as a result of decreased carrier activity driven primarily by T-Mobile and DISH Wireless, partially offset by an increase in activity from Verizon Wireless.

Operating Profit

Domestic site leasing segment operating profit increased $64.5 million for the year ended December 31, 2023, as compared to the prior year, primarily due to additional profit generated by (1) towers acquired and built since January 1, 2022, (2) organic site leasing growth as noted above, and (3) continued control of our site leasing cost of revenue.

International site leasing segment operating profit increased $88.8 million for the year ended December 31, 2023, as compared to the prior year. On a constant currency basis, international site leasing segment operating profit increased $86.7 million. These changes were primarily due to (1) additional profit generated by towers acquired and built since January 1, 2022 and (2) organic site leasing growth as noted above.

Site development segment operating profit decreased $19.2 million for the year ended December 31, 2023, as compared to the prior year, as a result of decreased carrier activity driven primarily by T-Mobile and DISH Wireless, partially offset by an increase in activity from Verizon Wireless.

Asset impairment and decommission costs increased $126.2 million for the year ended December 31, 2023, as compared to the prior year. On a constant currency basis, asset impairment and decommission costs increased $125.8 million for the year ended December 31, 2023. These changes were primarily as a result of an increase in impairment charges resulting from the planned abandonment of identified sites with minimal expectations of future economic benefit (primarily from Sprint and Oi related churn), partially offset by a $45.1 million benefit from the reassessment of the lease terms. The reassessment resulted in an overall shortening of the lease term and a reduction to the lease liability and right-of-use asset. For further information regarding our asset impairment and decommission costs, see Note 3 of our Consolidated Financial Statements included in this report.

Domestic site leasing depreciation, accretion, and amortization expense decreased $31.9 million for the year ended December 31, 2023, as compared to the prior year. This change was primarily due to the impact of assets that became fully depreciated since the prior year period, partially offset by an increase in the number of towers we acquired and built since January 1, 2022.

International site leasing depreciation, accretion, and amortization expense increased $39.2 million for the year ended December 31, 2023, as compared to the prior year. On a constant currency basis, depreciation, accretion, and amortization expense increased $37.8 million. These changes were primarily due to the increase in the number of towers we acquired and built since January 1, 2022, partially offset by the impact of assets that became fully depreciated since the prior year period.

Domestic site leasing operating income decreased $5.1 million for the year ended December 31, 2023, as compared to the prior year, primarily due to an increase in asset impairment and decommission costs, partially offset by higher segment operating profit and decreases in depreciation, accretion, and amortization expense and acquisition and new business initiatives related adjustments and expenses.

International site leasing operating income increased $29.7 million for the year ended December 31, 2023, as compared to the prior year. On a constant currency basis, international site leasing operating income increased $29.0 million. These changes were primarily due to higher segment operating profit and a decrease in acquisition and new business initiatives related adjustments and expenses, partially offset by increases in depreciation, accretion, and amortization expense, asset impairment and decommission costs, and selling, general, and administrative expenses.

Site development operating income decreased $19.2 million for the year ended December 31, 2023, as compared to the prior year, primarily due to lower segment operating profit driven by lower activity from T-Mobile and DISH Wireless and an increase in depreciation, accretion, and amortization expense, partially offset by a decrease in selling, general, and administrative expenses.

Other operating expense increased $7.2 million for the year ended December 31, 2023, as compared to the prior year, primarily due to increases in selling, general, and administrative expenses and asset impairment and decommission costs.

Interest income increased $8.2 million for the year ended December 31, 2023, as compared to the prior year. This change was primarily due to interest received on a loan to an unconsolidated joint venture, a higher amount of interest-bearing deposits held, as well as higher effective interest rates on those deposits as compared to the prior year.

Interest expense increased $46.6 million for the year ended December 31, 2023, as compared to the prior year. This change was primarily due to a higher weighted-average interest rate on our cash-interest bearing debt outstanding which remained flat year over year.

Non-cash interest expense decreased $10.2 million for the year ended December 31, 2023, as compared to the prior year. This change was primarily due to lower amortization of accumulated losses related to our interest rate swaps de-designated as cash flow hedges which reached their term end date in 2023.

Other income, net includes an $81.2 million gain on the remeasurement of U.S. dollar denominated intercompany loans with foreign subsidiaries and a $7.6 million loss on the sale of tower assets for the year ended December 31, 2023, while the prior year period included a $20.3 million gain on the remeasurement of U.S. dollar denominated intercompany loans with foreign subsidiaries.

Provision for income taxes decreased $15.0 million for the year ended December 31, 2023, as compared to the prior year. On a constant currency basis, provision for income taxes decreased $35.5 million. These changes were primarily due to a decrease in deferred domestic taxes, partially offset by an increase in foreign current and deferred taxes.

Net income increased $37.6 million for the year ended December 31, 2023, as compared to the prior year. This change was primarily due to fluctuations in foreign currency exchange rates including changes recorded on the remeasurement of the U.S. dollar denominated intercompany loans with foreign subsidiaries, decreases in provision for income taxes and non-cash interest expense and increases in operating income and interest income. This was partially offset by an increase in interest expense and a decrease in other income, net.

Year Ended 2022 Compared to Year Ended 2021

For a discussion of our 2022 Results of Operations, including a discussion of our financial results for the fiscal year ended December 31, 2022 compared to the fiscal year ended December 31, 2021, refer to Part I, Item 7 of our annual report on Form 10-K filed with the SEC on March 1, 2023.

NON-GAAP FINANCIAL MEASURES

This report contains information regarding Adjusted EBITDA, a non-GAAP measure. We have provided below a description of Adjusted EBITDA, a reconciliation of Adjusted EBITDA to its most directly comparable GAAP measure and an explanation as to why management utilizes this measure. This report also presents our financial results and other financial metrics after eliminating the impact of changes in foreign currency exchange rates. We believe that providing these financial results and metrics on a constant currency basis, which are non-GAAP measures, gives management and investors the ability to evaluate the performance of our business without the impact of foreign currency exchange rate fluctuations. We eliminate the impact of changes in foreign currency exchange rates by dividing the current period’s financial results by the average monthly exchange rates of the prior year period, as well as by eliminating the impact of the remeasurement of our intercompany loans.

Adjusted EBITDA

We define Adjusted EBITDA as net income excluding the impact of non-cash straight-line leasing revenue, non-cash straight-line ground lease expense, non-cash compensation, net loss from extinguishment of debt, other income and expenses, acquisition and new business initiatives related adjustments and expenses, asset impairment and decommission costs, interest income, interest expenses, depreciation, accretion, and amortization, and income taxes.

We believe that Adjusted EBITDA is useful to investors or other interested parties in evaluating our financial performance. Adjusted EBITDA is the primary measure used by management (1) to evaluate the economic productivity of our operations and (2) for purposes of making decisions about allocating resources to, and assessing the performance of, our operations. Management believes that Adjusted EBITDA helps investors or other interested parties to meaningfully evaluate and compare the results of our operations (1) from period to period and (2) to our competitors, by excluding the impact of our capital structure (primarily interest charges from our outstanding debt) and asset base (primarily depreciation, amortization, and accretion) from our financial results. Management also

believes Adjusted EBITDA is frequently used by investors or other interested parties in the evaluation of REITs. In addition, Adjusted EBITDA is similar to the measure of current financial performance generally used by our lenders to determine compliance with certain covenants under our Senior Credit Agreement and the indentures relating to the 2020 Senior Notes and 2021 Senior Notes. Adjusted EBITDA should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.

(2)Provision for income taxes includes $0.8 million and $2.1 million of franchise taxes for the year ended 2023 and 2022, respectively, reflected in selling, general, and administrative expenses on the Consolidated Statement of Operations.

Adjusted EBITDA increased $124.9 million for the year ended December 31, 2023, as compared to the prior year. On a constant currency basis, Adjusted EBITDA increased $122.4 million. These changes were primarily due to an increase in site leasing segment operating profit, partially offset by a decrease in site development segment operating profit and an increase in cash selling, general, and administrative expenses.

LIQUIDITY AND CAPITAL RESOURCES

SBAC is a holding company with no business operations of its own. SBAC’s only significant asset is 100% of the outstanding capital stock of SBA Telecommunications, LLC (“Telecommunications”), which is also a holding company that owns equity interests in entities that directly or indirectly own all of our domestic and international towers and assets. We conduct all of our business operations through Telecommunications’ subsidiaries. Accordingly, our only source of cash to pay our obligations, other than financings, is distributions with respect to our ownership interest in our subsidiaries from the net earnings and cash flow generated by these subsidiaries.

Operating Activities

Cash provided by operating activities was $1.5 billion for the year ended December 31, 2023 as compared to $1.3 billion for the year ended December 31, 2022. The increase was primarily due to an increase in cash inflows associated with working capital changes related to the timing of customer payments and increases in site leasing segment operating profit and interest income, partially offset by increases in cash interest expense, cash selling, general, and administrative expenses, and cash asset impairment and decommission costs as well as a decrease in site development segment operating profit.

(1)During the year ended December 31, 2022, we closed on 1,445 sites from Airtel Tanzania for $176.1 million.

(2)During the year ended December 31, 2022, we acquired 2,632 sites from GTS in Brazil for $728.2 million, net of working capital adjustments, of which $168.5 million is included in acquisitions of towers and related intangible assets and $559.8 million is included in acquisition of right of use assets.

(3)Excludes $17.6 million and $17.9 million spent to extend ground lease terms for the years ended December 31, 2023 and 2022, respectively.

(4)The year ended December 31, 2022 includes amounts paid related to the acquisition of a data center.

(5)The year ended December 31, 2023 includes $100.5 million of loan payments made to an unconsolidated joint venture.

Subsequent to December 31, 2023, we purchased or are under contract to purchase 281 communication sites for an aggregate consideration of $87.8 million in cash. We anticipate that these acquisitions will be consummated by the end of the third quarter of 2024.

For 2024, we expect to incur non-discretionary cash capital expenditures associated with tower maintenance and general corporate expenditures of $51.0 million to $61.0 million and discretionary cash capital expenditures, based on current or potential acquisition obligations, planned new tower construction, forecasted tower augmentations, and forecasted ground lease purchases, of $320.0 million to $340.0 million. We expect to fund these cash capital expenditures from cash on hand, cash flow from operations, and borrowings under the Revolving Credit Facility or new financings. The exact amount of our future cash capital expenditures will depend on a number of factors, including amounts necessary to support our tower portfolio, our new tower build and acquisition programs, and our ground lease purchase program.

The amount of future distributions will be determined, from time to time, by our Board of Directors to balance our goal of increasing long-term shareholder value and retaining sufficient cash to implement our current capital allocation policy, which prioritizes investment in quality assets that meet our return criteria, and then stock repurchases when we believe our stock price is below its intrinsic value. The actual amount, timing, and frequency of future dividends will be at the sole discretion of our Board of Directors and will be declared based upon various factors, many of which are beyond our control.

Debt Instruments and Debt Service Requirements

Terms of the Senior Credit Agreement

The Senior Credit Agreement requires SBA Senior Finance II to maintain specific financial ratios, including (1) a ratio of Consolidated Net Debt to Annualized Borrower EBITDA not to exceed 6.5 times for any fiscal quarter, (2) a ratio of Consolidated Net Debt (calculated in accordance with the Senior Credit Agreement) to Annualized Borrower EBITDA for the most recently ended fiscal quarter not to exceed 6.5 times for 30 consecutive days, and (3) a ratio of Annualized Borrower EBITDA to Annualized Cash Interest Expense (calculated in accordance with the Senior Credit Agreement) of not less than 2.0 times for any fiscal quarter. The Senior Credit Agreement contains customary affirmative and negative covenants that, among other things, limit the ability of SBA Senior Finance II and its subsidiaries to incur indebtedness, grant certain liens, make certain investments, enter into sale leaseback transactions, merge or consolidate, make certain restricted payments, enter into transactions with affiliates, and engage in certain asset dispositions, including a sale of all or substantially all of their property. The Senior Credit Agreement is also subject to customary events of default. Pursuant to the Second Amended and Restated Guarantee and Collateral Agreement, amounts borrowed under the Revolving Credit Facility, the Term Loans and certain hedging transactions that may be entered into by SBA Senior Finance II or the Subsidiary Guarantors (as defined in the Senior Credit Agreement) with lenders or their affiliates are secured by a first lien on the membership interests of SBA Telecommunications, LLC, SBA Senior Finance, LLC and SBA Senior Finance II and on substantially all of the assets (other than leasehold, easement and fee interests in real property) of SBA Senior Finance II and the Subsidiary Guarantors.

The Senior Credit Agreement permits SBA Senior Finance II, without the consent of the other lenders, to request that one or more lenders provide SBA Senior Finance II with increases in the Revolving Credit Facility or additional term loans provided that after giving effect to the proposed increase in Revolving Credit Facility commitments or incremental term loans the ratio of Consolidated Net Debt to Annualized Borrower EBITDA would not exceed 6.5 times. SBA Senior Finance II’s ability to request such increases in the Revolving Credit Facility or additional term loans is subject to its compliance with customary conditions set forth in the Senior Credit Agreement including compliance, on a pro forma basis, with the financial covenants and ratios set forth therein and, with respect to any additional term loan, an increase in the margin on existing term loans to the extent required by the terms of the Senior Credit Agreement. Upon SBA Senior Finance II’s request, each lender may decide, in its sole discretion, whether to increase all or a portion of its Revolving Credit Facility commitment or whether to provide SBA Senior Finance II with additional term loans and, if so, upon what terms. As of December 31, 2023, SBA Senior Finance II was in compliance with the financial covenants contained in the Senior Credit Agreement.

On July 3, 2023, we, through our wholly owned subsidiary, SBA Senior Finance II, amended our 2018 Term Loan and Revolving Credit Facility to replace LIBOR with Term SOFR as the benchmark interest rate and make related changes.

On January 25, 2024, we, through our wholly owned subsidiary SBA Senior Finance II, amended and restated our Senior Credit Agreement to (1) issue a new $2.3 billion Term Loan, (2) increase the total commitments under the Revolving Credit Facility from $1.5 billion to $1.75 billion, (3) extend the maturity date of the Revolving Credit Facility to January 25, 2029, and (4) amend certain other terms and conditions under the Senior Credit Agreement. The proceeds from the 2024 Term Loan were used to retire our 2018 Term Loan and to pay related fees and expenses.

On February 23, 2024, we, through our wholly owned subsidiary, SBA Senior Finance II LLC, further increased the total commitments under the Revolving Credit Facility from $1.75 billion to $2.0 billion.

Revolving Credit Facility under the Senior Credit Agreement

The Revolving Credit Facility consists of a revolving loan under which up to $1.5 billion ($2.0 billion as amended February 23, 2024) aggregate principal amount may be borrowed, repaid and redrawn, based upon specific financial ratios and subject to the satisfaction of other customary conditions to borrowing through the maturity date of July 7, 2026 (January 25, 2029 as amended). Amounts borrowed under the Revolving Credit Facility accrue interest, at SBA Senior Finance II’s election, at either (1) the Eurodollar Rate (or Term SOFR as amended July 3, 2023) plus a margin that ranges from 112.5 basis points to 150.0 basis points or (2) the Base Rate plus a margin that ranges from 12.5 basis points to 50.0 basis points, in each case based on the ratio of Consolidated

Table of Contents

Net Debt to Annualized Borrower EBITDA, calculated in accordance with the Senior Credit Agreement. In addition, SBA Senior Finance II is required to pay a commitment fee of between 0.15% and 0.25% per annum on the amount of unused commitment. Furthermore, the Revolving Credit Facility incorporates sustainability-linked targets which will adjust the Revolving Credit Facility’s applicable interest and commitment fee rates upward or downward based on how the Company performs against those targets. Borrowings under the Revolving Credit Facility may be used for general corporate purposes. SBA Senior Finance II may, from time to time, borrow from and repay the Revolving Credit Facility. Consequently, the amount outstanding under the Revolving Credit Facility at the end of the period may not be reflective of the total amounts outstanding during such period.

The key terms of the Revolving Credit Facility are as follows:

|  |  |  | Unused
|  | Interest Rate |  | Commitment
|  | as of |  | Fee as of
|  | December 31, 2023 (1) |  | December 31, 2023 (2)
Revolving Credit Facility |  | 6.435% |  | 0.140%

(1)The rate reflected includes a 0.050% reduction in the applicable spread as a result of meeting certain sustainability-linked targets as of December 31, 2022.

(2)The rate reflected includes a 0.010% reduction in the applicable commitment fee as a result of meeting certain sustainability-linked targets as of December 31, 2022.

The table below summarizes the Revolving Credit Facility’s activity during the years ended December 31, 2023 and 2022 (in thousands):

Subsequent to December 31, 2023, we repaid $110.0 million under the Revolving Credit Facility, and as of the date of this filing, $70.0 million was outstanding.

Term Loan under the Senior Credit Agreement

2018 Term Loan

On April 11, 2018, we, through our wholly owned subsidiary, SBA Senior Finance II, issued a term loan (the “2018 Term Loan”) under the amended and restated Senior Credit Agreement. The 2018 Term Loan consists of a senior secured term loan with an initial aggregate principal amount of $2.4 billion that matures on April 11, 2025. The 2018 Term Loan accrues interest, at SBA Senior Finance II’s election, at either the Base Rate plus 75 basis points (with a zero Base Rate floor) or the Eurodollar Rate plus 175 basis points (with a zero Eurodollar Rate floor). The 2018 Term Loan was issued at 99.75% of par value. As of December 31, 2023, the 2018 Term Loan was accruing interest at 7.210% per annum. On July 3, 2023, we, through our wholly owned subsidiary, SBA Senior Finance II, amended our 2018 Term Loan to replace LIBOR with Term SOFR as the benchmark interest rate. The amendment to Term SOFR includes a CSA of 0.10% which we include as part of interest expense. On January 25, 2024, we, through our wholly owned subsidiary, SBA Senior Finance II, retired the 2018 Term Loan using the proceeds from the issuance of the 2024 Term Loan.

Principal payments on the 2018 Term Loan were made in quarterly installments on the last day of each March, June, September, and December in an amount equal to $6.0 million. We incurred financing fees of approximately $16.8 million in relation to this transaction, which were being amortized through the maturity date.

During the year ended December 31, 2023, we repaid an aggregate of $24.0 million of principal on the 2018 Term Loan. As of December 31, 2023, the 2018 Term Loan had a principal balance of $2.3 billion.

2024 Term Loan

On January 25, 2024, we, through our wholly owned subsidiary, SBA Senior Finance II, issued a term loan (the “2024 Term Loan”) under the amended and restated Senior Credit Agreement. The 2024 Term Loan consists of a senior secured term loan with an initial aggregate principal amount of $2.3 billion that matures on January 25, 2031. The 2024 Term Loan accrues interest, at SBA Senior Finance II’s election, at either the Base Rate plus 100 basis points (with a zero Base Rate floor) or at Term SOFR plus 200 basis points (with a floor of 0%). The 2024 Term Loan was issued at 99.75% of par value. The proceeds from the 2024 Term Loan were used to retire our 2018 Term Loan and to pay related fees and expenses.

Principal payments on the 2024 Term Loan will be made in quarterly installments o n the last day of each March, June, September, and December in an amount equal to $5.75 million beginning on June 30, 2024. We incurred financing fees of approximately $19.5 million in relation to this transaction, which are being amortized through the maturity date.

Interest Rate Swaps

On August 4, 2020, we, through our wholly owned subsidiary, SBA Senior Finance II, entered into an interest rate swap which swapped $1.95 billion of notional value accruing interest at one month LIBOR plus 175 basis points for an all-in fixed rate of 1.874% per annum through July 31, 2023.

On June 21, 2023, we, through our wholly owned subsidiary, SBA Senior Finance II, amended our interest rate swap agreement which swapped $1.95 billion of notional value accruing interest at one month Term SOFR plus 185 basis points (inclusive of a CSA of 0.10%) for an all-in fixed rate of 1.900% from August 1, 2023 through January 25, 2024 (the repayment date of the 2018 Term Loan and issuance date of the 2024 Term Loan). The swap will remain in effect under the 2024 Term Loan and will swap $1.95 billion of notional value accruing interest at one month Term SOFR plus 200 basis points for an all-in fixed rate of 2.050% per annum through March 31, 2025. We concluded that the amendment to the interest rate swap qualifies for the relief provided by ASU 2021-01 and ASU 2022-06 and as such, have not de-designated our cash flow hedge.

On November 3, 2023, we, through our wholly owned subsidiary, SBA Senior Finance II, entered into a forward-starting interest rate swap agreement which will swap $1.0 billion of notional value accruing interest at one month Term SOFR plus 200 basis points for an all-in fixed rate of 5.830% per annum. The swap has an effective start date of March 31, 2025 and a maturity date of April 11, 2028.

Secured Tower Revenue Securities

Tower Revenue Securities Terms

As of December 31, 2023, we, through a New York common law trust (the “Trust”), had issued and outstanding an aggregate of $6.9 billion of Secured Tower Revenue Securities (“Tower Securities”). The sole asset of the Trust consists of a non-recourse mortgage loan made in favor of certain of our subsidiaries that are borrowers on the mortgage loan (the “Borrowers”) under which there is a loan tranche for each Tower Security outstanding with the same interest rate and maturity date as the corresponding Tower Security. The mortgage loan will be paid from the operating cash flows from the aggregate 9,892 tower sites owned by the Borrowers as of December 31, 2023. The mortgage loan is secured by (1) mortgages, deeds of trust, and deeds to secure debt on a substantial portion of the tower sites, (2) a security interest in the tower sites and substantially all of the Borrowers’ personal property and fixtures, (3) the Borrowers’ rights under certain tenant leases, and (4) all of the proceeds of the foregoing. For each calendar month, SBA Network Management, Inc., an indirect subsidiary (“Network Management”), is entitled to receive a management fee equal to 4.5% of the Borrowers’ operating revenues for the immediately preceding calendar month.

The Borrowers may prepay any of the mortgage loan components, in whole or in part, with no prepayment consideration, (1) within twelve months (in the case of the component corresponding to the 2019-1C Tower Securities, 2020-1C Tower Securities, 2021-1C Tower Securities, 2021-2C Tower Securities, and 2022-1C Tower Securities) or eighteen months (in the case of the components corresponding to the 2014-2C Tower Securities, 2020-2C Tower Securities, and 2021-3C Tower Securities) of the anticipated repayment date of such mortgage loan component, (2) with proceeds received as a result of any condemnation or casualty of any tower owned by the Borrowers or (3) during an amortization period. In all other circumstances, the Borrowers may prepay the mortgage loan, in whole or in part, upon payment of the applicable prepayment consideration. The prepayment consideration is determined based on the class of the Tower Securities to which the prepaid mortgage loan component corresponds and consists of an amount equal to the net present value associated with the portion of the principal balance being prepaid and calculated in accordance with the formula set forth in the mortgage loan agreement.

Table of Contents

To the extent that the mortgage loan components corresponding to the Tower Securities are not fully repaid by their respective anticipated repayment dates, the interest rate of each such component will increase by the greater of (1) 5% and (2) the amount, if any, by which the sum of (x) the 10 year U.S. treasury rate plus (y) the credit-based spread for such component (as set forth in the mortgage loan agreement) plus (z) 5%, exceeds the original interest rate for such component.

Pursuant to the terms of the Tower Securities, all rents and other sums due on any of the towers owned by the Borrowers are directly deposited by the lessees into a controlled deposit account and are held by the indenture trustee. The monies held by the indenture trustee after the release date are classified as short-term restricted cash on the Consolidated Balance Sheets (see Note 4). However, if the Debt Service Coverage Ratio, defined as the net cash flow (as defined in the mortgage loan agreement) divided by the amount of interest on the mortgage loan, servicing fees and trustee fees that the Borrowers are required to pay over the succeeding twelve months, as of the end of any calendar quarter, falls to 1.30x or lower, then all cash flow in excess of amounts required to make debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other payments required under the loan documents, referred to as “excess cash flow,” will be deposited into a reserve account instead of being released to the Borrowers. The funds in the reserve account will not be released to the Borrowers unless the Debt Service Coverage Ratio exceeds 1.30x for two consecutive calendar quarters. If the Debt Service Coverage Ratio falls below 1.15x as of the end of any calendar quarter, then an “amortization period” will commence and all funds on deposit in the reserve account will be applied to prepay the mortgage loan until such time that the Debt Service Coverage Ratio exceeds 1.15x for a calendar quarter. In addition, if any of the Tower Securities are not fully repaid by their respective anticipated repayment dates, the cash flow from the towers owned by the Borrowers will be trapped by the trustee for the Tower Securities and applied first to repay the interest, at the original interest rates, on the mortgage loan components underlying the Tower Securities, second to fund all reserve accounts and operating expenses associated with those towers, third to pay the management fees due to Network Management, fourth to repay principal of the Tower Securities and fifth to repay the additional interest discussed above. Furthermore, the advance rents reserve requirement states that the Borrowers are required to maintain an advance rents reserve at any time the monthly tenant Debt Service Coverage Ratio is equal to or less than 2:1 and for two calendar months after such coverage ratio again exceeds 2:1. The mortgage loan agreement, as amended, also includes covenants customary for mortgage loans subject to rated securitizations. Among other things, the Borrowers are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets.

Subsequent to such date, the senior notes become redeemable until maturity at 100% of the principal plus accrued and unpaid interest.

Indentures Governing Senior Notes

The Indentures governing the Senior Notes contain customary covenants, subject to a number of exceptions and qualifications, including restrictions on the ability of SBAC and Telecommunications to (1) incur additional indebtedness unless the Consolidated Indebtedness to Annualized Consolidated Adjusted EBITDA Ratio (as defined in the Indenture), pro forma for the additional indebtedness does not exceed, with respect to any fiscal quarter, 9.5x for SBAC, (2) merge, consolidate, or sell assets, (3) make restricted payments, including dividends or other distributions, (4) enter into transactions with affiliates, and (5) enter into sale and leaseback transactions and restrictions on the ability of the Restricted Subsidiaries of SBAC (as defined in the Indentures) to incur liens securing indebtedness.

Debt Service

As of December 31, 2023, we believe that our cash on hand, capacity available under our Revolving Credit Facility, and cash flows from operations for the next twelve months will be sufficient to service our outstanding debt during the next twelve months.

The following table illustrates our estimate of our debt service requirement for the twelve months ended December 31, 2024 based on the amounts outstanding as of December 31, 2023 and the interest rates accruing on those amounts on such date (in thousands):

Revolving Credit Facility (1) |  | $ | 13,431
2018 Term Loan (2)(3) |  |  | 83,978
2014-2C Tower Securities |  |  | 639,078
2019-1C Tower Securities |  |  | 33,409
2020-1C Tower Securities |  |  | 14,368

2020 Senior Notes |  |  | 58,125
2021 Senior Notes |  |  | 46,875
Total debt service for the next 12 months (4) |  | $ | 1,019,399

41

Table of Contents

(1)As of December 31, 2023, $180.0 million was outstanding under the Revolving Credit Facility. Subsequent to December 31, 2023, we repaid $110.0 million under the Revolving Credit Facility, and as of the date of this filing, $70.0 million was outstanding.

(2)Total debt service on the 2018 Term Loan includes the impact of the interest rate swaps amended on June 21, 2023, which swapped $1.95 billion of notional value accruing interest at Term SOFR plus 185 basis points (inclusive of a CSA of 0.10%) for an all-in fixed rate of 1.900% per annum from August 1, 2023 through March 31, 2025.

(3)On January 25, 2024, we repaid in full the 2018 Term Loan with proceeds from the 2024 Term Loan.

(4)Our total debt service does not include any amounts for the 2024 Term Loan. Total debt service for the twelve months ended December 31, 2024 related to the 2024 Term Loan is projected to be $78.8 million, which reflects interest from January 25, 2024 (the issuance date of the 2024 Term Loan) and three quarterly installment payments.

Inflation

The impact of inflation on our operations has not been material to date. However, the impact of rising interest rates, due to actions by the Federal Reserve to combat inflation, has impacted, and is expected to continue to impact, our growth rate and future operating results. Increasing interest rates has impacted, and is expected to continue to impact, the ability and willingness of wireless service providers to incur capital expenditures at prior levels to expand their networks, which could adversely affect our future revenue growth rates. In addition, increased interest rates may adversely affect our costs to refinance our indebtedness at maturity. In addition, persistent high rates of inflation could adversely affect our future operating results particularly in light of the fact that our site leasing revenues are governed by long-term contracts with pre-determined pricing that we will not be able to increase in response to increases in inflation other than our contracts in South America, South Africa, the Philippines, and Tanzania which have inflationary index based rent escalators.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to certain market risks that are inherent in our financial instruments. These instruments arise from transactions entered into in the normal course of business.

(1)On January 25, 2024, we repaid our 2018 Term Loan and issued a new $2.3 billion Term Loan with a maturity date of January 25, 2031 and extended the maturity date of the Revolving Credit Facility to January 25, 2029.

Table of Contents

Revolving Credit Facility at an average interest rate of 6.435% as of December 31, 2023, the 2020 Senior Notes interest rate of 3.875%, and the 2021 Senior Notes interest rate of 3.125%.

Our current primary market risk exposure is (1) interest rate risk relating to our ability to refinance our debt at commercially reasonable rates, if at all, and (2) interest rate risk relating to the impact of interest rate movements on the variable portion of our 2018 Term Loan, 2024 Term Loan, and any borrowings that we may incur under our Revolving Credit Facility, which are at floating rates. We manage the interest rate risk on our outstanding debt through our large percentage of fixed rate debt, including interest rate swaps. On August 4, 2020, and amended June 21, 2023, we, through our wholly owned subsidiary, SBA Senior Finance II, entered into an interest rate swap which swapped $1.95 billion of notional value accruing interest at (i) one month LIBOR plus 175 basis points for an all-in fixed rate of 1.874% per annum through July 31, 2023, (ii) one month Term SOFR plus 185 basis points (inclusive of a CSA of 0.10%) for an all-in fixed rate of 1.900% per annum from August 1, 2023 through January 25, 2024, and (iii) one month Term SOFR plus 200 basis points for an all-in fixed rate of 2.050% per annum from January 25, 2024 through March 31, 2025. On November 3, 2023, we entered into a forward-starting interest rate swap agreement which will swap $1.0 billion of notional value accruing interest at one month Term SOFR plus 200 basis points for an all-in fixed rate of 5.830% per annum. The swap has an effective start date of March 31, 2025 and a maturity date of April 11, 2028. While we cannot predict our ability to refinance existing debt or the impact interest rate movements will have on our existing debt, we continue to evaluate our financial position on an ongoing basis.

We have performed a sensitivity analysis assuming a hypothetical 1% increase in our variable interest rates as of December 31, 2023. As of December 31, 2023, the analysis indicated that such an adverse movement would have caused our interest expense to increase by approximately 4.8% for the year ended December 31, 2023.

We are exposed to market risk from changes in foreign currency exchange rates in connection with our operations in Brazil, Canada, Chile, Peru, Colombia, Costa Rica, South Africa, the Philippines, Tanzania, and to a lesser extent, our markets in Central America. In each of these countries, we pay most of our selling, general, and administrative expenses and a portion of our operating expenses, such as taxes and utilities incurred in the country in local currency. In addition, in Brazil, Canada, Chile, South Africa, and the Philippines, we receive significantly all of our revenue and pay significantly all of our operating expenses in local currency. In Colombia, Costa Rica, Peru, and Tanzania, we receive our revenue and pay our operating expenses in a mix of local currency and U.S. dollars. All transactions denominated in currencies other than the U.S. Dollar are reported in U.S. Dollars at the applicable exchange rate. All assets and liabilities are translated into U.S. Dollars at exchange rates in effect at the end of the applicable fiscal reporting period, and all revenues and expenses are translated at average rates for the period. The cumulative translation effect is included in equity as a component of Accumulated other comprehensive income (loss). For the year ended December 31, 2023, approximately 21.7% of our revenues and approximately 26.9% of our total operating expenses were denominated in foreign currencies.

We have performed a sensitivity analysis assuming a hypothetical 10% adverse movement in the Brazilian Real from the quoted foreign currency exchange rates at December 31, 2023. The analysis indicated that such an adverse movement would have caused our revenues and operating income to decline by approximately 1.3% and 0.9%, respectively, for the year ended December 31, 2023.

As of December 31, 2023, we had intercompany debt, which is denominated in a currency other than the functional currency of the subsidiary in which it is recorded. As settlement of this debt is anticipated or planned in the foreseeable future, any changes in the foreign currency exchange rates will result in unrealized gains or losses, which will be included in our determination of net income. A change of 10% in the underlying exchange rates of our unsettled intercompany debt at December 31, 2023 would have resulted in approximately $119.7 million of unrealized gains or losses that would have been included in Other income (expense), net in our Consolidated Statements of Operations for the year ended December 31, 2023.

ITEM 9A. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures – We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Exchange Act, is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, as ours are designed to do, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

In connection with the preparation of this Annual Report on Form 10-K, as of December 31, 2023, an evaluation was performed under the supervision and with the participation of our management, including the CEO and CFO, of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act). Based on such evaluation, our CEO and CFO concluded that, as of December 31, 2023, our disclosure controls and procedures were effective.

There has been no change in our internal control over financial reporting during the quarter ended December 31, 2023 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Management’s Annual Report on Internal Control over Financial Reporting – Management is responsible for establishing and maintaining adequate internal control over financial reporting, and for performing an assessment of the effectiveness of internal control over financial reporting as of December 31, 2023. 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. Our system of internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of SBAC; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of SBAC are being made only in accordance with authorizations of management and directors of SBAC; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of SBAC’s assets that could have a material effect on the financial statements.

Management performed an assessment of the effectiveness of SBAC’s internal control over financial reporting as of December 31, 2023 based upon criteria in Internal Control – Integrated Framework (2013 Framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on our assessment, management determined that SBAC’s internal control over financial reporting was effective as of December 31, 2023 based on the criteria in Internal Control – Integrated Framework (2013 Framework) issued by COSO.

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.

Ernst & Young LLP, the independent registered public accounting firm that audited the financial statements included in this Annual Report on Form 10-K, has issued an attestation report on SBAC’s internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of SBA Communications Corporation

Opinion on Internal Control Over Financial Reporting

We have audited SBA Communications Corporation and subsidiaries’ internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, SBA Communications Corporation and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income, shareholders’ deficit and cash flows for each of the three years in the period ended December 31, 2023, and the related notes and financial statement schedule listed in the Index at Item 15(a) and our report dated February 28, 2024 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

ITEM 9B. OTHER INFORMATION

(a) Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

Cavanagh Employment Agreement

On February 19, 2024, the Company entered into an amended and restated employment agreement with Brendan T. Cavanagh (the “Employment Agreement”), which reflects Mr. Cavanagh’s promotion to President and Chief Executive Officer and extends the term of his employment until December 31, 2026. The Employment Agreement increases Mr. Cavanagh’s annual base salary to $920,000 and his target bonus to 150% of his annual base salary in effect at the start of such year, each effective as of January 1, 2024. Payment of the bonus is contingent upon the achievement of performance goals established and assessed solely at the discretion of the Compensation Committee of the Company’s Board of Directors.

Pursuant to the Employment Agreement, Mr. Cavanagh is entitled to a severance payment, upon his termination without Cause or for Good Reason (each as defined in the Employment Agreement), equal to the sum of (i) an amount equal to the pro rata portion of the minimum annual bonus target for the period of service in the year in which the termination or resignation occurs, and (ii) an amount equal to the applicable multiple multiplied by the sum of (a) Mr. Cavanagh’s base salary for the year in which the termination or resignation occurs, (b) the minimum annual bonus target, and (c) the greater of (1) $33,560 and (2) the value of all medical, dental, health, life and other fringe benefit plans for the year in which the termination or resignation occurs (the “Severance Payment”). The Severance Payment is payable in a lump sum. The applicable multiple for Mr. Cavanagh will be two, in the event the termination occurs for Cause or Good Reason and three, in the event the termination occurs on or after a change in control of the Company.

Additionally, upon the occurrence of a change in control (i) the term of Mr. Cavanagh’s employment will automatically be extended for three years following the effective date of such change in control, and (ii) Mr. Cavanagh will be entitled to an amount equal to the Severance Payment. All other material terms of the Employment Agreement remain the same, including the provisions for severance benefits, change in control benefits, and the provisions for non-competition, non-interference, non-disparagement and non-disclosure provisions during his employment and for a period of twelve months after termination.

Executive Severance Plan

On October 25, 2023, the Company adopted the SBA Communications Corporation Executive Severance Plan (the “Executive Severance Plan”) in order to retain certain executives of the Company and to ensure their continued dedication to their duties, including in the event of a change in control. The Executive Severance Plan provides severance benefits to the Executive Vice Presidents of the Company, which includes Messrs. Richard M. Cane, Mark Ciarfella, Joshua Koenig, Marc Montagner, and Jason Silberstein (each, a “Participant”) whose employment is terminated by the Company for any reason or by the Participant for Good Reason (as defined in the Executive Severance Plan).

Pursuant to the Executive Severance Plan, if a Participant’s employment with the Company is terminated by the Company without Cause or if the Participant resigns for Good Reason, then a Participant is entitled to (i) an amount equal to the sum of (a) an amount equal to the pro rata portion of the target annual incentive bonus for the period of service in the year in which the termination or resignation occurs, and (b) an amount equal to the applicable multiple multiplied by the sum of (x) the Participant’s respective base salary in effect for the year of termination or resignation, and (y) the Participant’s target annual incentive bonus in effect immediately prior to the Participant’s termination of employment; and (ii) continuation of applicable medical, dental and life insurance benefits, subject to the terms of the Executive Severance Plan. The applicable multiple, with respect to the Executive Severance Plan means one, in the event the termination occurs for Cause or Good Reason and two, in the event the termination occurs on or after a change in control of the Company.

Additionally, if the Participant’s employment is terminated due to Death or Disability (as defined in the Executive Severance Plan), the Participant is entitled to receive an amount equal to the pro rata portion of the Participant’s respective target annual incentive bonus for the period of service in the year in which the Death or Disability occurs.

(b) 10b5-1 Trading Plans

During the three months ended December 31, 2023, none of our officers (as defined in Rule 16a-1(f) of the Exchange Act) or directors adopted or terminated a "Rule 10b5-1 trading arrangement" or "non-Rule 10b5-1 trading arrangement," as each term is defined in Item 408(d) of Regulation S-K.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of SBA Communications Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of SBA Communications Corporation and subsidiaries (the Company) as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income, shareholders' deficit and cash flows for each of the three years in the period ended December 31, 2023, and the related notes and financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 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 U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control–Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 28, 2024 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

|  | Accounting for Ground Leases
Description of the Matter |  | As more fully described in Note 2 to the consolidated financial statements, the Company recognizes a right-of-use asset and a lease liability for its operating lease contracts, initially measured at the present value of the lease payments over the lease term. As of December 31, 2023, the Company had $2.2 billion of operating lease right-of-use assets, net, $271.8 million of current operating lease liabilities, and $1.9 billion of long-term lease liabilities. For the period ended December 31, 2023, the total operating lease right-of-use assets obtained for new operating lease liabilities were $55.3 million and adjustments associated with lease modifications and reassessments were a reduction of $86.7 million. The Company’s primary operating lease obligations are its long-term lease contracts for land that underlies its tower structures. The Company’s ground leases generally do not provide a readily determinable implicit discount rate. When the rate implicit in the lease is not readily determinable, the Company calculates the present value of the lease payments by estimating the Company’s incremental borrowing rate (“IBR”). The IBR is the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term in a similar economic environment. The IBR is computed on a lease-by-lease basis when the Company enters into a new lease, upon a lease modification, or upon a lease reassessment event. Auditing the Company’s accounting for ground leases was complex because of the significant uncertainty associated with inputs into the IBR. The process to estimate the Company’s IBR includes the use of subjective inputs, considers the public credit rating of the Company, observable debt yields of the Company and the related debt’s seniority, and adjustments for leases denominated in different currencies, to determine the IBR over the remaining lease term.
How We Addressed the Matter in Our Audit |  | We obtained an understanding, evaluated and tested the design and operating effectiveness of the Company’s internal controls related to determining the IBR used in accounting for ground leases. For example, we tested the Company’s controls over the review of the accounting policy, including the methodology and assumptions used to estimate the IBR. To test the Company’s accounting for ground leases, our audit procedures included, among others, evaluating the methodology used to calculate the IBR, and evaluating the assumptions and underlying data used by the Company to estimate the IBR. We involved our valuation specialists to assist in the evaluation of the methodologies and assumptions applied to estimate the IBR. We compared the Company’s credit rating used in the IBR estimate to independent third-party sources and compared the Company’s existing borrowing rate for collateralized assets to observable debt yields of the Company. We also evaluated the Company’s disclosures included in Note 2 to the consolidated financial statements.

We have served as the Company’s auditor since 2002.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A summary of the significant accounting policies applied in the preparation of the accompanying consolidated financial statements is as follows:

Principles of Consolidation

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the Company and its majority and wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The significant estimates made by management relate to the allowance for doubtful accounts, the costs and revenue relating to the Company’s construction contracts, stock-based compensation assumptions, valuation allowance related to deferred tax assets, fair value of long-lived assets, the useful lives of towers and intangible assets, anticipated property tax assessments, incremental borrowing rate for lease accounting, fair value of investments, and asset retirement obligations. Management develops estimates based on historical experience and on various assumptions about the future that are believed to be reasonable based on the information available. These estimates ultimately may differ from actual results and such differences could be material.

The Company is in the process of reviewing the remaining estimated useful lives of its towers and intangible assets and is considering, for U.S. GAAP purposes, whether it should modify its current estimates for asset lives based on its historical operating experience. The Company has retained an independent consultant to assist in completing this review and analysis. The Company currently depreciates its towers on a straight-line basis over the shorter of the term of the underlying ground lease (including renewal options) taking into account residual value or the estimated useful life of the tower, which the Company has historically estimated to be 15 years. Additionally, certain of the Company’s intangible assets are amortized on a similar basis to its tower assets, as the estimated useful lives of such intangible assets correlate to the useful life of the towers. If the Company concludes that a revision in the estimated useful lives of its towers and intangible assets is appropriate based on its review and analysis, the Company will account for any changes in the useful lives as a change in accounting estimate under Accounting Standards Codification (“ASC”) 250

F-9

Table of Contents

Accounting Changes and Error Corrections, which will be recorded prospectively beginning in the period of change. Based on preliminary information obtained to date, the Company expects that its estimated asset lives may be extended, which would result in prospective (i) decreases in depreciation and amortization and (ii) increases in the right of use asset and operating lease liability, and such changes could be material to future depreciation and amortization and the Company’s consolidated results of operations. The Company expects to conclude its analysis in the first quarter of 2024.

Cash and Cash Equivalents

Cash and cash equivalents consist primarily of cash in banks, money market funds, commercial paper, highly liquid short-term investments, and other marketable securities with an original maturity of three months or less at the time of purchase. These investments are carried at cost, which approximates fair value.

Restricted Cash

The Company classifies all cash pledged as collateral to secure certain obligations and all cash whose use is limited as restricted cash. This includes cash held in escrow to fund certain reserve accounts relating to the Tower Securities as well as for payment and performance bonds and surety bonds issued for the benefit of the Company in the ordinary course of business, as well as collateral associated with workers’ compensation plans (see Note 4).

Investments

Investment securities with original maturities of more than three months but less than one year at time of purchase are considered short-term investments and are classified in prepaid expenses and other current assets on the accompanying Consolidated Balance Sheets. The Company’s short-term investments primarily consist of certificates of deposit with maturities of less than a year. Investment securities with maturities of more than a year are considered long-term investments and are classified in other assets on the accompanying Consolidated Balance Sheets. Long-term investments consist of strategic investments in companies and are accounted for under the cost and equity method. Gross purchases and proceeds from sales of the Company’s investments are presented within Cash flows from investing activities on the Company’s Consolidated Statements of Cash Flows. During the year ended December 31, 2023 and 2022, no gain or loss was recorded related to the sale or maturity of investments.

Property and Equipment

Property and equipment are recorded at cost or at estimated fair value (in the case of acquired properties), adjusted for asset impairment and estimated asset retirement obligations. Costs for self-constructed towers include direct materials and labor, indirect costs and capitalized interest. Approximately $0.9 million, $0.6 million, and $0.5 million of interest cost was capitalized in 2023, 2022 and 2021, respectively.

Depreciation on towers and related components is provided using the straight-line method over the estimated useful lives, not to exceed the minimum lease term of the underlying ground lease. To determine the lease term, the Company considers all renewal periods that are reasonably certain to be exercised, taking into consideration all economic factors, including the communications site’s estimated economic life and the respective lease terms of the Company’s tenants under the existing lease arrangements on such site. Leasehold improvements are amortized on a straight-line basis over the shorter of the useful life of the improvement or the minimum lease term of the lease. For all other property and equipment, depreciation is provided using the straight-line method over the estimated useful lives.

The Company performs ongoing evaluations of the estimated useful lives of its property and equipment for depreciation purposes. The estimated useful lives are determined and continually evaluated based on the period over which services are expected to be rendered by the asset. If the useful lives of assets are reduced, depreciation may be accelerated in future years. Property and equipment under capital leases are amortized on a straight-line basis over the term of the lease or the remaining estimated life of the leased property, whichever is shorter, and the related amortization is included in depreciation expense. Expenditures for maintenance and repair are expensed as incurred.

Asset classes and related estimated useful lives are as follows:

Towers and related components | 3 - 15 years
Furniture, equipment, and vehicles | 2 - 7 years
Data Centers, buildings, and leasehold improvements | 10 - 30 years

F-10

Table of Contents

Betterments, improvements, and significant repairs, which increase the value or extend the life of an asset, are capitalized and depreciated over the estimated useful life of the respective asset. Changes in an asset’s estimated useful life are accounted for prospectively, with the book value of the asset at the time of the change being depreciated over the revised remaining useful life. There has been no material impact for changes in estimated useful lives for any years presented.

Deferred Financing Fees

Financing fees related to the issuance of debt have been deferred and are being amortized using the effective interest rate method over the expected duration of the related indebtedness (see Note 11). For all of the Company’s debt, except for the Revolving Credit Facility where the debt issuance costs are being presented as an asset on the accompanying Consolidated Balance Sheets, debt issuance costs are presented on the balance sheet as a direct deduction from the related debt liability rather than as an asset.

Intangible Assets

The Company classifies as intangible assets the fair value of current leases in place at the acquisition date of towers and related assets (referred to as the “Current contract intangibles”), and the fair value of future tenant leases anticipated to be added to the acquired towers (referred to as the “Network location intangibles”). These intangibles are estimated to have a useful life consistent with the useful life of the related tower assets, which is typically 15 years. For all intangible assets, amortization is provided using the straight-line method over the estimated useful lives as the benefit associated with these intangible assets is anticipated to be derived evenly over the life of the asset.

Impairment of Long-Lived Assets

The Company evaluates its individual long-lived and related assets with finite lives for indicators of impairment to determine when an impairment analysis should be performed. The Company evaluates its tower assets and Current contract intangibles at the tower level, which is the lowest level for which identifiable cash flows exists. The Company evaluates its Network location intangibles for impairment at the tower leasing business level. The Company has established a policy to at least annually, or earlier if indicators of impairment arise, evaluate its tower assets and Current contract and Network location intangibles for impairment.

The Company records an impairment charge when an investment in towers or related assets has been impaired, such that future undiscounted cash flows would not recover the then current carrying value of the investment in the tower and related intangible. If the future undiscounted cash flows are lower than the carrying value of the investment in the tower and related intangible, the Company calculates future discounted cash flows and compares those amounts to the carrying value. The Company records an impairment charge for any amounts lower than the carrying value. Estimates and assumptions inherent in the impairment evaluation include, but are not limited to, general market and economic conditions, historical operating results, geographic location, lease-up potential, and expected timing of lease-up. In addition, the Company makes certain assumptions in determining an asset’s fair value for the purpose of calculating the amount of an impairment charge.

The Company recognized impairment charges of $169.4 million, $43.2 million, and $33.0 million for the years ended December 31, 2023, 2022 and 2021, respectively. Refer to Note 3 for further detail of these amounts.

Fair Value Measurements

The Company determines the fair market values of its financial instruments based on the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The following three levels of inputs may be used to measure fair value:

Level 1 | Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
Level 2 | Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3 | Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Revenue Recognition and Accounts Receivable

Site leasing revenues

Revenue from site leasing is recognized on a straight-line basis over the current term of the related lease agreements. Receivables recorded related to the straight-line impact of site leases are reflected in other assets on the Consolidated Balance Sheets. Rental amounts received in advance are recorded as deferred revenue on the Consolidated Balance Sheets. Revenues from site leasing represent 93% of the Company’s total revenues for the year ended December 31, 2023. For additional information on tenant leases, refer to the Leases section below.

Site development revenues

Site development projects in which the Company performs consulting services include contracts on a fixed price basis that are billed at contractual rates. Revenue is recognized over time based on milestones achieved, which are determined based on costs incurred. Amounts billed in advance (collected or uncollected) are recorded as deferred revenue on the Consolidated Balance Sheets.

Revenue from construction projects is recognized over time, determined by the percentage of cost incurred to date compared to management’s estimated total cost for each contract. This method is used because management considers total cost to be the best available measure of progress on the contracts. These amounts are based on estimates, and the uncertainty inherent in the estimates initially is reduced as work on the contracts nears completion. Refer to Note 5 for further detail of costs and estimated earnings in excess of billings on uncompleted contracts. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined to be probable.

The site development segment represents approximately 7% of the Company’s total revenues for the year ended December 31, 2023. The Company accounts for site development revenue in accordance with ASC 606, Revenue from Contracts with Customers. Payment terms do not result in any significant financing arrangements. Furthermore, these contracts do not typically include variable consideration; therefore, the transaction price that is recognized over time is generally the amount of the total contract.

Accounts receivable

The accounts receivable balance was $182.7 million and $184.4 million as of December 31, 2023 and 2022, respectively, of which $32.3 million and $59.6 million related to the site development segment as of December 31, 2023 and 2022, respectively. Refer to Note 15 for further detail of the site development segment.

Credit Losses

According to ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, an expected credit loss impairment model is used for financial instruments, including trade receivables, which requires entities to consider forward-looking information to estimate expected credit losses over the lifetime of the asset, resulting in earlier recognition of losses for receivables that are current or not yet due. The Company’s expected credit loss allowance methodology for accounts receivable is developed using historical collection experience, current and future economic and market conditions, and a review of the current status of customers’ trade accounts receivables. Due to the short-term nature of such receivables, the estimate of the amount of accounts receivable that may not be collected considers aging of the accounts receivable balances and the financial condition of customers. Additionally, specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default. The Company’s monitoring activities include timely account reconciliation, dispute resolution, payment confirmation, consideration of customers’ financial condition, and macroeconomic conditions. Balances are written off when determined to be uncollectible. ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments – Credit Losses (“ASU 2018-19”) clarified that operating lease receivables are not within the scope of ASC 326-20 and should instead be accounted for under the new leasing standard, ASC 842. The Company is exposed to credit losses which are subject to this standard primarily through the site development business segment which provides consulting and construction related services.

(2)Amounts include annual installment payments related to the Oi S.A. reorganization. The fourth and final annual installment payment was received during the year ended December 31, 2022.

Cost of Revenue

Cost of site leasing revenue includes ground lease rent, property taxes, amortization of deferred lease costs, maintenance, fuel, energy, and other tower operating expenses. Cost of site development revenue includes the cost of materials, salaries, and labor costs, including payroll taxes, subcontract labor, vehicle expense, and other costs directly and indirectly related to the projects. All costs related to site development projects are recognized as incurred.

Income Taxes

The Company recognizes deferred tax assets and liabilities for the estimated future tax consequences attributable to differences between the financial reporting and tax bases of existing assets and liabilities. Deferred tax assets and liabilities are measured using tax rates in effect for the year in which the temporary differences are expected to reverse. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets if it is "more-likely-than-not" that those assets will not be realized. The Company considers many factors when assessing the likelihood of future realization, including the Company’s recent cumulative earnings by taxing jurisdiction, expectations of future taxable income, prudent and feasible tax planning strategies that are available, the carryforward periods available to the Company for tax reporting purposes and other relevant factors.

The Company began operating as a REIT for federal income tax purposes effective January 1, 2016. As a REIT, the Company generally is not subject to corporate level federal income tax on taxable income it distributes to its stockholders as long as it meets the organizational and operational requirements under the REIT rules. However, certain subsidiaries have made an election with the IRS to be treated as a taxable REIT subsidiary (“TRS”) in conjunction with the Company's REIT election. The TRS elections permit the Company to engage in certain business activities in which the REIT may not engage directly, so long as these activities are conducted in entities that elect to be treated as TRSs under the Code. A TRS is subject to federal and state income taxes on the income from these activities. Additionally, the Company has included in TRSs the Company’s tower operations in most foreign jurisdictions; however, the REIT holds selected tower assets in certain foreign jurisdictions. Those operations will continue to be subject to foreign taxes in the jurisdiction in which such assets and operations are located regardless of whether they are included in a TRS.

The Company will continue to file separate federal tax returns for the REIT and TRS for the year ended December 31, 2023. The REIT had taxable income during the year ended December 31, 2023 and paid a dividend and utilized net operating losses (“NOLs”) to offset its remaining 2023 distribution requirement. Some of the Company’s TRSs generated NOLs which will be carried forward to use in future years. A portion of the deferred tax asset generated by the NOLs are reserved by a valuation allowance.

Stock-Based Compensation

The Company measures and recognizes compensation expense for all share-based payment awards made to employees and directors, including stock options, restricted stock units (“RSUs”), performance-based restricted stock units (“PSUs”), and purchases under the Company’s employee stock purchase plans. The Company records compensation expense, for stock options, RSUs, and PSUs on a straight-line basis over the vesting period; however, compensation expense related to certain PSUs are subject to adjustment on performance relative to the established targets. Compensation expense for stock options is based on the estimated fair value of the options on the date of the grant using the Black-Scholes option-pricing model. Compensation expense for RSUs and PSUs

F-13

Table of Contents

is based on the fair market value of the units awarded at the date of the grant. Fair value for a portion of the PSUs was calculated using a Monte Carlo simulation model.

Asset Retirement Obligations

The Company has entered into ground leases for the land underlying the majority of the Company’s towers. A majority of these leases require the Company to remove improvements only or restore land interests to their original condition upon termination of the ground lease.

In determining the measurement of the asset retirement obligations, the Company considered the nature and scope of the contractual restoration obligations contained in the Company’s ground leases, the historical retirement experience as an indicator of future restoration probabilities, intent in renewing existing ground leases through lease termination dates, current and future value, timing of estimated restoration costs, and the credit adjusted risk-free rate used to discount future obligations.

The Company recognizes asset retirement obligations in the period in which they are incurred, if a reasonable estimate of a fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the related tower fixed assets, and over time, the liability is accreted to its present value each period and the capitalized cost is depreciated over the estimated useful life of the tower. As of December 31, 2023 and 2022, the asset retirement obligation was $119.3 million and $79.8 million, respectively, and is included in other long-term liabilities on the Consolidated Balance Sheets. Upon settlement of the obligations, any difference between the cost to retire an asset and the recorded liability is recorded in Asset impairment and decommission costs on the Consolidated Statements of Operations.

Comprehensive Income (Loss)

Comprehensive income (loss) is defined as the change in equity (net assets) of a business enterprise during a period from transactions and other events and circumstances from non-owner sources, and is comprised of net income (loss), foreign currency adjustments, and adjustments related to interest rate swaps designated as cash flow hedges.

Foreign Currency Translation

All assets and liabilities of foreign subsidiaries that do not utilize the U.S. dollar as its functional currency are translated at period-end exchange rates, while revenues and expenses are translated at monthly average exchange rates during the year. Unrealized translation gains and losses are reported as foreign currency translation adjustments through Accumulated other comprehensive loss, net in the Consolidated Statement of Shareholders’ Deficit.

For foreign subsidiaries where the U.S. dollar is the functional currency, monetary assets and liabilities of such subsidiaries, which are not denominated in U.S. dollars, are remeasured at exchange rates in effect at the balance sheet date, and revenues and expenses are remeasured at monthly average rates prevailing during the year. Remeasurement gains and losses are reported as Other income (expense), net in the Consolidated Statements of Operations.

Intercompany Loans Subject to Remeasurement

In accordance with ASC 830, the Company remeasures foreign denominated intercompany loans with the corresponding change in the balance being recorded in Other income (expense), net in the Consolidated Statements of Operations as settlement is anticipated or planned in the foreseeable future. The Company recorded a $52.4 million gain, a $12.9 million gain, and a $44.3 million loss, net of taxes, on the remeasurement of intercompany loans for the years ended December 31, 2023, 2022, and 2021, respectively. During the year ended December 31, 2023, the Company funded $4.2 million and repaid $223.4 million under its intercompany loan agreements. As of December 31, 2023 and 2022, the aggregate amount outstanding under the intercompany loan agreements subject to remeasurement with the Company’s foreign subsidiaries was $1.3 billion and $1.5 billion, respectively. Subsequent to year end, the Company repaid an additional $15.0 million under its intercompany loan agreements.

Acquisitions

Under ASU 2017-01, Clarifying the Definition of a Business, the Company’s acquisitions will generally qualify for asset acquisition treatment under ASC 360, Property, Plant, and Equipment, rather than business combination treatment under ASC 805 Business Combinations. For acquisitions, the aggregate purchase price is allocated on a relative fair value basis to towers and related intangible assets. The fair values of these net assets acquired are based on management’s estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary valuation procedures and techniques. The fair value

F-14

Table of Contents

estimates are based on available historical information and on future expectations and assumptions deemed reasonable by management at the time. If the actual results differ from the estimates and judgments used in these fair values, the amounts recorded in the consolidated financial statements could be subject to a possible impairment of the intangible assets or require acceleration of the amortization expense of intangible assets in subsequent periods. External, direct transaction costs will be capitalized as a component of the cost of the asset acquired. The Company will continue to expense internal acquisition costs as incurred. For business combinations, the estimates of the fair value of the assets acquired and liabilities assumed at the date of an acquisition are subject to adjustment during the measurement period (up to one year from the particular acquisition date). During the measurement period, the Company will adjust assets and/or liabilities if new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would have resulted in a revised estimated value of those assets and/or liabilities as of that date. As of December 31, 2023, there were no material acquisitions with purchase price allocations that were preliminary.

In connection with certain acquisitions, the Company may agree to pay contingent consideration (or earnouts) in cash or stock if the communication sites or businesses that are acquired meet or exceed certain performance targets over a period of one year to three years after they have been acquired. Contingent consideration in connection with asset acquisitions will be recognized at the time when the contingency is resolved or becomes payable and will increase the cost basis of the assets acquired.

Leases

ASU No. 2016-02, Leases (“Topic 842”) requires all lessees to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments and any prepaid rent amounts. The Company has elected not to separate nonlease components from the associated lease component for all underlying classes of assets.

The components of the right-of-use lease liabilities as of December 31, 2023 and 2022 are as follows (in thousands):

|  |  |  |  | December 31, |  | December 31,
|  |  |  |  | 2023 |  | 2022

Long-term lease liabilities |  |  |  |  | $ | 1,865,686 |  | $ | 2,040,628

Operating Leases

Ground leases. The Company enters into long-term lease contracts for land that underlies its tower structures. Ground lease agreements generally include renewal options which can be exercised exclusively at the Company’s election. To determine the lease term, the Company considers all renewal periods that are reasonably certain to be exercised, taking into consideration all economic factors, including the communications site’s estimated economic life and the respective lease terms of the Company’s tenants under the existing lease arrangements on such site.

Substantially all leases provide for rent rate escalations. In the United States and the Company’s international markets, ground leases and other property interests typically either (1) contain specific annual rent escalators or (2) escalate annually in accordance with an inflationary index. Increases or decreases in lease payments that result from subsequent changes in the index or rate are accounted for as variable lease payments.

Office leases. The Company’s office leases consist of long-term leases for international, regional, and certain site development office locations. Office leases include a single lease component, lease of the office space, and sometimes nonlease components such as common area maintenance expenses. The lease term for office leases are generally considered to be the contractually committed term.

Finance Leases

Vehicle leases. The Company leases vehicles that are used in its site development business. These leases are accounted for as financing leases and have lease terms that are contractually committed and do not include optional renewal terms.

F-15

Table of Contents

Acquired right-of-use assets. In connection with certain acquisitions, the Company may acquire the exclusive right to lease and operate communication sites for a period that represents (1) a major part of the remaining economic life of the underlying assets and/or (2) the purchase price represents substantially all of the fair value of the underlying asset. The Company accounts for these arrangements as financing leases. Payments associated with the right-of-use of these assets are typically fully funded at the acquisition date and will be recognized over the respective lease term. The right-of-use assets related to these transactions are recorded in Acquired and other right-of-use assets, net on the Consolidated Balance Sheets.

Discount Rate

When available, the Company uses the rate implicit in the lease to discount lease payments to present value. However, the Company’s ground leases generally do not provide a readily determinable implicit rate. Therefore, the Company estimates the incremental borrowing rate to discount lease payments based on information available at lease commencement or upon a modification. The Company uses publicly available data for instruments with similar characteristics when calculating its incremental borrowing rates.

Lease Cost

Variable lease payments include escalations based on an inflationary index and are initially recognized using the prevailing index at the date of initial measurement or upon reassessment of the lease term. Subsequent changes in standard cost of living increases are recognized as variable lease costs. Variable lease payments also include contingent rent provisions.

The components of lease cost, lease term, and discount rate as of December 31, 2023 and 2022 are as follows:

|  |  |  |  | For the year ended December 31,
|  |  |  |  | 2023 |  | 2022

Tenant (Operating) Leases

The Company enters into long-term lease contracts with wireless service providers to lease antenna space on towers that it owns or operates. Each tenant lease relates to the lease or use of space at an individual site. Tenant leases are generally for an initial term of five years to fifteen years with multiple renewal periods, which are at the option of the tenant. Tenant leases typically (1) contain specific annual rent escalators, (2) escalate annually in accordance with an inflationary index, or (3) escalate using a combination of fixed and inflation adjusted escalators, including the renewal option periods.

Tenant lease agreements generally include renewal options which can be exercised exclusively at the tenant’s election. The only common exception is if the Company no longer has a right to the ground underlying the site, the lease agreements permit the

F-16

Table of Contents

Company to terminate the lease. Despite high frequency of renewal of options to extend the lease by its tenants, the Company has concluded that the exercise of a renewal option by a tenant is not reasonably certain of occurrence; therefore, only the current committed term is included in the determination of the lease term.

Certain tenant leases provide for a reimbursement of costs incurred by the Company. The Company pays these costs directly and is not relieved of the primary obligation for the expenses. These reimbursements are recorded as revenue on the Statements of Operations.

Deferred Lease Costs

ASU 2016-02 defines initial direct costs as incremental costs that would not have been incurred if the lease had not been obtained. These costs, including commissions paid related to the origination of specific tenant leases, are deferred and amortized over the remaining lease term. Initial direct costs were approximately $3.2 million, $3.3 million, and $2.9 million for the years ended December 31, 2023, 2022, and 2021, respectively. Amortization expense related to deferred initial direct costs was $2.3 million, $1.9 million, and $1.4 million for the years ended December 31, 2023, 2022, and 2021, respectively. As of December 31, 2023 and 2022, unamortized deferred initial direct costs were $8.7 million and $7.7 million, respectively, and are included in other assets on the Consolidated Balance Sheets.

Reference Rate Reform

On June 21, 2023, the Company amended its interest rate swap to change from LIBOR as an interest rate benchmark to the replacement benchmark of Term SOFR effective on August 1, 2023. The Company elected the optional expedient which allows companies to change the reference rate and other critical terms related to the reference rate reform in derivative hedge documentation without having to de-designate the hedging relationship, allowing the Company to continue applying hedge accounting to its cash flow hedge. On July 3, 2023, the Company amended its 2018 Term Loan and its Revolving Credit Facility to use Term SOFR as the benchmark rate. The transition from LIBOR to Term SOFR did not have a material impact on the consolidated financial statements. Refer to Notes 11 and 21 for further discussion of the 2018 Term Loan, Revolving Credit Facility, and the Company’s interest rate swap.

Derivatives and Hedging Activities

The Company enters into interest rate swaps to hedge the future interest expense from variable rate debt and reduce the Company’s exposure to fluctuations in interest rates. At inception, the Company evaluates the interest rate swaps to determine whether they qualify for hedge accounting. In accordance with ASU 2017-12 (ASC 815 - Derivatives and Hedging), hedge accounting should be provided only if the derivative hedging instrument is expected to be, and actually is, effective at offsetting changes in fair values or cash flows of the hedged item. The effective portion of the gain or loss is recorded in Accumulated other comprehensive loss, net on the Consolidated Balance Sheets. The ineffective portion of the gain or loss from the interest rate swap is recognized in earnings immediately. On a quarterly basis, the Company evaluates whether the cash flow hedge remains highly effective in offsetting changes in cash flows. Refer to Note 21 for further discussion of the interest rate swaps.

3.FAIR VALUE MEASUREMENTS

Items Measured at Fair Value on a Recurring Basis—The Company’s asset retirement obligations are measured at fair value on a recurring basis using Level 3 inputs and are recorded in Other long-term liabilities in the Consolidated Balance Sheets. The fair value of the asset retirement obligations is calculated using a discounted cash flow model.

Refer to Note 20 for discussion of the Company’s redeemable noncontrolling interests.

Items Measured at Fair Value on a Nonrecurring Basis— The Company estimates the fair value of assets subject to impairment using a discounted cash flow ("DCF") (Level 3 input) analysis. Determining fair value requires the exercise of significant judgments, including the amount and timing of expected future cash flows, long-term growth rates, discount rates and relevant comparable earnings and trading multiples. The cash flows employed in the DCF analysis are based on estimates of future revenues, earnings, and cash flows after considering factors such as tower location demographics, timing of additions of new tenants, lease rates, rate and term of renewal, attrition, ongoing cash requirements, and market multiples. Each of the assumptions are applied based on the specific facts and circumstances of the identified assets at the lowest level of identifiable cash flows. The DCF analysis used an average discount rates ranging from 6.5%- 8.8%.

(1)Represents impairment charges resulting from the Company’s regular analysis of whether the anticipated future cash flows from certain towers are sufficient to recover the carrying value of the investment in those towers. Impairment charges for the year ended December 31, 2023 includes the impact of the planned abandonment of identified sites with minimal expectations of future economic benefit (primarily from Sprint and Oi related churn), partially offset by a $45.1 million benefit from the reassessment of the lease terms. The reassessment resulted in an overall shortening of the lease term and a reduction to the lease liability and right-of-use asset.

The Company’s long-term investments were $24.5 million and $40.7 million as of December 31, 2023 and 2022, respectively, and are recorded in Other assets on the Consolidated Balance Sheets. The estimation of the fair value of the investment involves the use of Level 3 inputs. The Company evaluates these investments for indicators of impairment. The Company considers impairment indicators such as negative changes in industry and market conditions, financial performance, business prospects, and other relevant events and factors. If indicators exist and the fair value of the investment is less than the carrying amount, an impairment charge will be recorded. During the year ended December 31, 2023 and 2022, the Company recognized an impairment loss of $4.7 million and $0.9 million, respectively, associated with its investments. The Company did not recognize any impairment loss associated with its investments during the years ended December 31, 2021.

Fair Value of Financial Instruments— The carrying values of cash and cash equivalents, accounts receivable, restricted cash, accounts payable, and short-term investments approximate their estimated fair values due to the short maturity of these instruments. The Company’s estimate of its short-term investments is based primarily upon Level 1 reported market values. As of December 31, 2023 and 2022, the Company had $1.0 million and $1.3 million of short-term investments, respectively. The Company purchased and sold $1.3 billion, $0.9 billion, and $1.7 billion of short-term investments for the years ended December 31, 2023, 2022, and 2021, respectively.

The Company determines fair value of its debt instruments utilizing various Level 2 sources including quoted prices and indicative quotes (non-binding quotes) from brokers that require judgment to interpret market information including implied credit spreads for similar borrowings on recent trades or bid/ask prices. The fair value of the Revolving Credit Facility is considered to approximate the carrying value because the Company does not believe its credit risk has changed materially from the date the applicable Eurodollar Rate (or Term SOFR as amended July 3, 2023) was set for the Revolving Credit Facility (112.5 to 150.0 basis points). Refer to Note 11 for the fair values, principal balances, and carrying values of the Company’s debt instruments.

Pursuant to the terms of the Tower Securities (see Note 11), the Company is required to establish a securitization escrow account, held by the indenture trustee, into which all rents and other sums due on the towers that secure the Tower Securities are directly deposited by the lessees. These restricted cash amounts are used to fund reserve accounts for the payment of (1) debt service costs, (2) ground rents, real estate and personal property taxes, and insurance premiums related to towers, (3) trustee and servicing expenses, and (4) management fees. The restricted cash in the securitization escrow account in excess of required reserve balances is subsequently released to the Borrowers (as defined in Note 11) monthly, provided that the Borrowers are in compliance with their debt service coverage ratio and that no event of default has occurred. All monies held by the indenture trustee are classified as restricted cash on the Company’s Consolidated Balance Sheets.

Payment and performance bonds relate primarily to collateral requirements for tower construction currently in process by the Company. Other restricted cash includes $6.1 million and $6.0 million held in escrow as of December 31, 2023 and 2022, respectively, related to the Company’s acquisition activities. Cash is pledged as collateral related to surety bonds issued for the benefit of the Company or its affiliates in the ordinary course of business and primarily related to the Company’s tower removal obligations. As of December 31, 2023 and 2022, the Company had $42.0 million and $42.3 million in surety and payment and performance bonds, respectively, for which no collateral was required to be posted.

Terms of the Senior Credit Agreement

The Senior Credit Agreement requires SBA Senior Finance II to maintain specific financial ratios, including (1) a ratio of Consolidated Net Debt to Annualized Borrower EBITDA not to exceed 6.5 times for any fiscal quarter, (2) a ratio of Consolidated Net Debt (calculated in accordance with the Senior Credit Agreement) to Annualized Borrower EBITDA for the most recently ended fiscal quarter not to exceed 6.5 times for 30 consecutive days and (3) a ratio of Annualized Borrower EBITDA to Annualized Cash Interest Expense (calculated in accordance with the Senior Credit Agreement) of not less than 2.0 times for any fiscal quarter. The Senior Credit Agreement contains customary affirmative and negative covenants that, among other things, limit the ability of SBA Senior Finance II and its subsidiaries to incur indebtedness, grant certain liens, make certain investments, enter into sale leaseback transactions, merge or consolidate, make certain restricted payments, enter into transactions with affiliates, and engage in certain asset dispositions, including a sale of all or substantially all of their property. The Senior Credit Agreement is also subject to customary events of default. Pursuant to the Second Amended and Restated Guarantee and Collateral Agreement, amounts borrowed under the Revolving Credit Facility, the Term Loans and certain hedging transactions that may be entered into by SBA Senior Finance II or the Subsidiary Guarantors (as defined in the Senior Credit Agreement) with lenders or their affiliates are secured by a first lien on the membership interests of SBA Telecommunications, LLC, SBA Senior Finance, LLC and SBA Senior Finance II and on substantially all of the assets (other than leasehold, easement and fee interests in real property) of SBA Senior Finance II and the Subsidiary Guarantors.

The Senior Credit Agreement permits SBA Senior Finance II, without the consent of the other lenders, to request that one or more lenders provide SBA Senior Finance II with increases in the Revolving Credit Facility or additional term loans provided that after giving effect to the proposed increase in Revolving Credit Facility commitments or incremental term loans the ratio of Consolidated Net Debt to Annualized Borrower EBITDA would not exceed 6.5 times. SBA Senior Finance II’s ability to request such increases in the Revolving Credit Facility or additional term loans is subject to its compliance with customary conditions set forth in the Senior Credit Agreement including compliance, on a pro forma basis, with the financial covenants and ratios set forth therein and, with respect to any additional term loan, an increase in the margin on existing term loans to the extent required by the terms of the Senior Credit Agreement. Upon SBA Senior Finance II’s request, each lender may decide, in its sole discretion, whether to increase all or a portion of its Revolving Credit Facility commitment or whether to provide SBA Senior Finance II with additional term loans and,

if so, upon what terms. As of December 31, 2023, SBA Senior Finance II was in compliance with the financial covenants contained in the Senior Credit Agreement.

On July 3, 2023, the Company, through its wholly owned subsidiary, SBA Senior Finance II, amended its 2018 Term Loan and Revolving Credit Facility to replace LIBOR with Term SOFR as the benchmark interest rate and make related changes.

On January 25, 2024, the Company, through its wholly owned subsidiary SBA Senior Finance II, amended and restated its Senior Credit Agreement to (1) issue a new $2.3 billion Term Loan, (2) increase the total commitments under its Revolving Credit Facility from $1.5 billion to $1.75 billion, (3) extend the maturity date of its Revolving Credit Facility to January 25, 2029, and (4) amend certain other terms and conditions under the Senior Credit Agreement.

On February 23, 2024 the Company, through its wholly owned subsidiary, SBA Senior Finance II LLC, further increased the total commitments under the Revolving Credit Facility from $1.75 billion to $2.0 billion.

Revolving Credit Facility under the Senior Credit Agreement

The Revolving Credit Facility consists of a revolving loan under which up to $1.5 billion ($2.0 billion as amended February 23, 2024) aggregate principal amount may be borrowed, repaid and redrawn, based upon specific financial ratios and subject to the satisfaction of other customary conditions to borrowing through the maturity date of July 7, 2026 (January 25, 2029 as amended). Amounts borrowed under the Revolving Credit Facility accrue interest, at SBA Senior Finance II’s election, at either (1) the Eurodollar Rate (or Term SOFR as amended July 3, 2023) plus a margin that ranges from 112.5 basis points to 150.0 basis points or (2) the Base Rate plus a margin that ranges from 12.5 basis points to 50.0 basis points, in each case based on the ratio of Consolidated Net Debt to Annualized Borrower EBITDA, calculated in accordance with the Senior Credit Agreement. In addition, SBA Senior Finance II is required to pay a commitment fee of between 0.15% and 0.25% per annum on the amount of unused commitment. Furthermore, the Revolving Credit Facility incorporates sustainability-linked targets which will adjust the Revolving Credit Facility’s applicable interest and commitment fee rates upward or downward based on how the Company performs against those targets. Borrowings under the Revolving Credit Facility may be used for general corporate purposes. SBA Senior Finance II may, from time to time, borrow from and repay the Revolving Credit Facility. Consequently, the amount outstanding under the Revolving Credit Facility at the end of the period may not be reflective of the total amounts outstanding during such period.

The key terms of the Revolving Credit Facility are as follows:

|  |  |  | Unused
|  | Interest Rate |  | Commitment
|  | as of |  | Fee as of
|  | December 31, 2023 (1) |  | December 31, 2023 (2)
Revolving Credit Facility |  | 6.435% |  | 0.140%

(1)

(1)The rate reflected includes a 0.050% reduction in the applicable spread as a result of meeting certain sustainability-linked targets as of December 31, 2022.

(2)The rate reflected includes a 0.010% reduction in the applicable commitment fee as a result of meeting certain sustainability-linked targets as of December 31, 2022.

Secured Tower Revenue Securities

Tower Revenue Securities Terms

As of December 31, 2023, the Company, through a New York common law trust (the “Trust”), had issued and outstanding an aggregate of $6.9 billion of Secured Tower Revenue Securities (“Tower Securities”). The sole asset of the Trust consists of a non-recourse mortgage loan made in favor of certain of the Company’s subsidiaries that are borrowers on the mortgage loan (the “Borrowers”) under which there is a loan tranche for each Tower Security outstanding with the same interest rate and maturity date as the corresponding Tower Security. The mortgage loan will be paid from the operating cash flows from the aggregate 9,892 tower sites owned by the Borrowers as of December 31, 2023. The mortgage loan is secured by (1) mortgages, deeds of trust, and deeds to secure debt on a substantial portion of the tower sites, (2) a security interest in the tower sites and substantially all of the Borrowers’ personal property and fixtures, (3) the Borrowers’ rights under certain tenant leases, and (4) all of the proceeds of the foregoing. For each calendar month, SBA Network Management, Inc., an indirect subsidiary (“Network Management”), is entitled to receive a management fee equal to 4.5% of the Borrowers’ operating revenues for the immediately preceding calendar month.

The Borrowers may prepay any of the mortgage loan components, in whole or in part, with no prepayment consideration, (1) within twelve months (in the case of the component corresponding to the 2019-1C Tower Securities, 2020-1C Tower Securities, 2021-1C Tower Securities, 2021-2C Tower Securities, and 2022-1C Tower Securities) or eighteen months (in the case of the components corresponding to the 2014-2C Tower Securities, 2020-2C Tower Securities, and 2021-3C Tower Securities) of the anticipated repayment date of such mortgage loan component, (2) with proceeds received as a result of any condemnation or casualty of any tower owned by the Borrowers or (3) during an amortization period. In all other circumstances, the Borrowers may prepay the mortgage loan, in whole or in part, upon payment of the applicable prepayment consideration. The prepayment consideration is determined based on the class of the Tower Securities to which the prepaid mortgage loan component corresponds and consists of an amount equal to the net present value associated with the portion of the principal balance being prepaid and calculated in accordance with the formula set forth in the mortgage loan agreement.

To the extent that the mortgage loan components corresponding to the Tower Securities are not fully repaid by their respective anticipated repayment dates, the interest rate of each such component will increase by the greater of (1) 5% and (2) the amount, if any, by which the sum of (x) the 10 year U.S. treasury rate plus (y) the credit-based spread for such component (as set forth in the mortgage loan agreement) plus (z) 5%, exceeds the original interest rate for such component.

Pursuant to the terms of the Tower Securities, all rents and other sums due on any of the towers owned by the Borrowers are directly deposited by the lessees into a controlled deposit account and are held by the indenture trustee. The monies held by the indenture trustee after the release date are classified as short-term restricted cash on the Consolidated Balance Sheets (see Note 4). However, if the Debt Service Coverage Ratio, defined as the net cash flow (as defined in the mortgage loan agreement) divided by the amount of interest on the mortgage loan, servicing fees and trustee fees that the Borrowers are required to pay over the succeeding twelve months, as of the end of any calendar quarter, falls to 1.30 x or lower, then all cash flow in excess of amounts required to make debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other payments required under the loan documents, referred to as “excess cash flow,” will be deposited into a reserve account instead of being released to the Borrowers. The funds in the reserve account will not be released to the Borrowers unless the Debt Service Coverage Ratio exceeds 1.30 x for two consecutive calendar quarters. If the Debt Service Coverage Ratio falls below 1.15 x as of the end of any calendar quarter, then an “amortization period” will commence and all funds on deposit in the reserve account will be applied to prepay the mortgage loan until such time that the Debt Service Coverage Ratio exceeds 1.15 x for a calendar quarter. In addition, if any of the Tower Securities are not fully repaid by their respective anticipated repayment dates, the cash flow from the towers owned by the Borrowers will be trapped by the trustee for the Tower Securities and applied first to repay the interest, at the original interest rates, on the mortgage loan components underlying the Tower Securities, second to fund all reserve accounts and operating expenses associated with those towers, third to pay the management fees due to Network Management, fourth to repay principal of the Tower Securities and fifth to repay the additional interest discussed above. Furthermore, the advance rents reserve requirement states that the Borrowers are required to maintain an advance rents reserve at any time the monthly tenant Debt Service Coverage Ratio is equal to or less than 2:1 and for two calendar months after such coverage ratio again exceeds 2:1. The mortgage loan agreement, as amended, also includes covenants customary for mortgage loans subject to rated securitizations. Among other things, the Borrowers are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets.

12.SHAREHOLDERS’ EQUITY

Common Stock Equivalents

The Company has outstanding stock options, time-based restricted stock units (“RSUs”), and performance-based restricted stock units (“PSUs”) which were considered in the Company’s diluted earnings per share calculation (see Note 16).

Registration of Additional Shares

The Company filed a shelf registration statement on Form S-4 with the Securities and Exchange Commission registering 4.0 million shares of its Class A common stock in 2007. These shares may be issued in connection with acquisitions of wireless communication towers or antenna sites and related assets or companies that own wireless communication towers, antenna sites, or related assets. During the years ended December 31, 2023 and 2022, the Company did not issue any shares of Class A common stock under this registration statement. As of December 31, 2023, the Company had approximately 1.2 million shares of Class A common stock remaining under this registration statement.

On February 26, 2021, the Company filed with the Securities and Exchange Commission an automatic shelf registration statement for well-known seasoned issuers on Form S-3ASR, which enables the Company to issue shares of its Class A common stock, preferred stock, debt securities, warrants, or depositary shares as well as units that include any of these securities. The Company will file a prospectus supplement containing the amount and type of securities each time it issues securities using its automatic shelf registration statement on Form S-3ASR. For the years ended December 31, 2023 and 2022, the Company did no t issue any securities under this automatic shelf registration statement.

On August 6, 2020, the Company filed a registration statement on Form S-8 with the Securities and Exchange Commission registering 3.4 million shares of the Company’s Class A common stock, consisting of 3.0 million shares of Class A common stock issuable under the 2020 Performance and Equity Incentive Plan (the “2020 Plan”) and 400,000 shares of Class A common stock subject to awards granted under the 2010 Performance and Equity Incentive Plan (the “2010 Plan”) that may become available for issuance or reissuance, as applicable, under the 2020 Plan if such awards are forfeited or are settled in cash or otherwise expire or terminate without the delivery of the shares (see Note 13).

Stock Repurchases

The Company’s Board of Directors authorizes the Company to purchase, from time to time, outstanding Class A common stock through open market repurchases in compliance with Rule 10b-18 under the Exchange Act, and/or in privately negotiated transactions at management’s discretion based on market and business conditions, applicable legal requirements, and other factors. Once authorized, the repurchase plan has no time deadline and will continue until otherwise modified or terminated by the Company’s Board of Directors at any time in its sole discretion. Shares repurchased are retired. On October 28, 2021, the Company’s Board of Directors authorized a new $1.0 billion stock repurchase plan, replacing the prior plan. As of the date of this filing, the Company had $404.7 million of authorization remaining under the new plan.

Dividends

As a REIT, the Company is required to distribute annually at least 90% of its REIT taxable income after the utilization of any available NOLs (determined before the deduction for dividends paid and excluding any net capital gain). As of December 31, 2023, $382.3 million of the federal NOLs are attributes of the REIT. The Company may use these NOLs to offset its REIT taxable income, and thus any required distributions to shareholders may be reduced or eliminated until such time as the Company’s NOLs have been fully utilized. The amount of future distributions will be determined, from time to time, by the Board of Directors to balance the Company’s goal of increasing long-term shareholder value and retaining sufficient cash to implement the Company’s current capital allocation policy, which prioritizes investment in quality assets that meet the Company’s return criteria, and then stock repurchases when the Company believes its stock price is below its intrinsic value. The actual amount, timing, and frequency of future dividends will be at the sole discretion of the Board of Directors and will be declared based upon various factors, many of which are beyond the Company’s control.

For the year ended December 31, 2023, the Company paid the following cash dividends:

13.STOCK-BASED COMPENSATION

On February 25, 2020, the Company’s 2010 Plan expired by its terms. On May 14, 2020, the Company’s shareholders approved the 2020 Plan which provides for the issuance of up to 3.0 million shares of the Company’s Class A common stock (of which approximately 2.2 million shares remain available for future issuance as of December 31, 2023), plus additional shares of Class A common stock (a) subject to awards granted under the 2010 Plan that may become available for issuance or reissuance, as applicable, under the 2020 Plan if such awards are forfeited or are settled in cash or otherwise expire or terminate without the delivery of the shares or (b) which become issuable under the 2020 Plan by reason of any stock dividend, stock split, recapitalization or other similar transaction effected without the receipt of consideration which results in an increase in the number of outstanding shares of Class A common stock.

Commencing with the 2020 equity award, the Company modified the type of equity granted to certain employees to align long-term compensation with Company performance. Under the new structure, the Company continued to issue RSUs; however, RSUs will now vest ratably over three years rather than four years. The Company further replaced stock options with PSUs which will cliff vest at the end of three year s. PSUs have performance metrics for which threshold, target, and maximum parameters are established at the time of the grant. The performance metrics are used to calculate the number of shares that will be issuable when the

awards vest, which may range from zero to 200% of the target amounts. At the end of each three year performance period, the number of shares that vest will depend on the results achieved against the pre-established performance metrics. Furthermore, effective with the 2020 grant, RSUs and PSUs will accrue dividend equivalents prior to vesting, which will be paid out only in respect to shares that actually vest.

Stock Options

The Company records compensation expense for employee stock options based on the estimated fair value of the options on the date of grant using the Black-Scholes option-pricing model with the assumptions included in the table below. The Company uses a combination of historical data and historical volatility to establish the expected volatility, as well as to estimate the expected option life. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the estimated life of the option. The following assumptions were used to estimate the fair value of options granted using the Black-Scholes option-pricing model:

|  |  |  |  | For the year ended December 31,
|  |  |  |  | 2023 |  | 2022
Risk free interest rate |  |  |  |  |  | 3.96% |  |  | 2.53%
Dividend yield |  |  |  |  |  | 1.50% |  |  | 0.9%
Expected volatility |  |  |  |  |  | 30.0% |  |  | 27.2%
Expected lives |  |  |  |  |  | 4.4 years |  |  | 4.3 years

There were no options granted during the year ended December 31, 2021.

14.INCOME TAXES

A s discussed in Note 2, the Company began operating in compliance with REIT requirements for federal income tax purposes effective January 1, 2016. As a REIT, the Company must distribute at least 90 percent of its taxable income (including dividends paid to it by its TRSs) except to the extent offset by NOLs. In addition, the Company must meet a number of other organizational and operational requirements. It is management's intention to adhere to these requirements and maintain the Company's REIT status. Most states where the Company operates conform to the federal rules recognizing REITs. Certain subsidiaries have made an election with the Company to be treated as TRSs in conjunction with the Company's REIT election; the TRS elections permit the Company to engage in certain business activities in which the REIT may not engage directly. A TRS is subject to federal and state income taxes on the income from these activities. A provision for taxes of the TRSs and of foreign branches of the REIT is included in its consolidated financial statements.

As of December 31, 2022, $16,173 and $60,939 are included in Other assets and Other long-term liabilities, respectively, on the accompanying Consolidated Balance Sheet.

A deferred tax asset is reduced by a valuation allowance if based on the weight of all available evidence, including both positive and negative evidence, it is more likely than not (a likelihood of more than 50%) that the value of such assets will not be realized. The valuation allowance should be sufficient to reduce the deferred tax asset to the amount that is more likely than not to be realized. The realization of deferred tax assets, including carryforwards and deductible temporary differences, depends upon the existence of sufficient taxable income of the same character during the carryback or carryforward period. All sources of taxable income available to realize the deferred tax asset, including the future reversal of existing temporary differences, future taxable income exclusive of reversing temporary differences and carryforwards, taxable income in carryback years and tax-planning strategies, should be considered.

The Company has recorded a valuation allowance for certain deferred tax assets as management believes that it is not “more-likely-than-not” that the Company will generate sufficient taxable income in future periods to recognize the assets. Valuation allowances of $16.1 million and $73.5 million were being carried to offset net deferred income tax assets as of December 31, 2023 and 2022, respectively. The net change in the valuation allowance for the years ended December 31, 2023 and 2022 was a decrease of $57.4 million and an increase of $7.4 million, respectively. The primary reason for the reduction in the valuation allowance was the Company released the valuation allowance related to the deferred tax asset balance of the domestic TRS.

The Company has available at December 31, 2023, a federal NOL carry-forward of approximately $4 34.5 million. $4 00.3 million of these NOL carry-forwards will expire between 2026 and 2037, and $34.2 million have an indefinite carry-forward. As of December 31, 2023, $382.3 million of the federal NOLs are attributes of the REIT. The Company may use these NOLs to offset its REIT taxable income, and thus any required distributions to shareholders may be reduced or eliminated until such time as the NOLs have been fully utilized. The Internal Revenue Code places limitations upon the future availability of NOLs based upon changes in the equity of the Company. If these occur, the ability of the Company to offset future income with existing NOLs may be limited. In addition, the Company has available at December 31, 2023, a foreign NOL carry-forward of $89.4 million and a net state operating tax loss carry-forward of approximately $2 62.5 million. These net operating tax loss carry-forwards began to expire in 2024.

The tax losses generated in tax years 2006 and forward remain subject to audit adjustment, and tax years 2016 and forward are op en to examination by the major jurisdictions in which the Company operates.

The Company is subject to income tax and other taxes in the geographic areas where it holds assets or operates, and the Company periodically receives notifications of audits, assessments, or other actions by taxing authorities. In certain jurisdictions, taxing authorities may issue notices and assessments that may not be reflective of the actual tax liability for which the Company will ultimately be liable. In the process of responding to assessments of taxes that the Company believes are not reflective of the Company’s actual tax liability, the Company avails itself of both administrative and judicial remedies. The Company evaluates the circumstances of each notification or assessment based on the information available and, in those instances in which the Company does not anticipate a successful defense of positions taken in its tax filings, a liability is recorded in the appropriate amount based on the underlying assessment.

The Company records a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return if applicable. As of December 31, 2023 and 2022, the total amount of unrecognized tax benefits are $14.2 million and $0.0 million, respectively, all of which would impact the effective rate if recognized. The Company expects the unrecognized tax benefits to change over the next 12 months if the applicable statute of limitations expire and the impact could range from zero to $2.3 million. For the period ended December 31, 2023 the Company recorded penalties and interest expense related to unrecognized tax benefits of $4.5 million as interest expense.

A reconciliation of the beginning and ending amount of unrecognized tax benefits are as follows:

In connection with a current assessment in Brazil, the taxing authorities have issued income tax deficiencies related to purchase accounting adjustments for tax years 2016 through 2019. The Company disagrees with the assessment and have filed an appeal with the higher appellate taxing authorities. The Company estimates that there is a more likely than not probability that the Company’s position will be sustained upon appeal. Accordingly, no liability has been recorded. The Company will continue to vigorously contest the adjustments and expect to exhaust all administrative and judicial remedies necessary to resolve the matters, which could be a lengthy process. There can be no assurance that these matters will be resolved in the Company’s favor, and an adverse outcome, or any future tax examinations involving similar assertions, could have a material effect on the Company’s results of operations or cash flows in any one period. As of December 31, 2023, the Company estimates the aggregate range of reasonably possible losses in excess of amounts accrued to be between zero and $97.8 million. This range excludes penalties and interest, which as of such date would have been $104.6 million.

The Company removed the permanent reinvestment assertion as of December 31, 2018 for all foreign earnings of the Company’s foreign jurisdictions. The Company subsequently also removed its permanent reinvestment assertion on the investment in the Company’s Guatemala, El Salvador, and Nicaragua subsidiaries. As a result, the Company has recorded cumulative deferred foreign withholding taxes of $8.3 million at December 31, 2023. No additional income taxes have been provided for any additional outside basis difference inherent in these entities, as these amounts continue to be indefinitely reinvested in foreign operations except as noted in Guatemala, El Salvador, and Nicaragua. The deferred incomes taxes related to the Guatemala, El Salvador, and Nicaragua subsidiaries are immaterial and determining the amount of unrecognized deferred tax liability for any additional outside basis differences in indefinitely reinvested entities is not practicable.

The U.S. government enacted comprehensive tax legislation in the form of the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act subjects a U.S. shareholder to tax on Global Intangible Low-Taxed Income (“GILTI”) earned by certain foreign subsidiaries. The FASB Staff Q&A, Topic 740, No. 5, Accounting for Global Intangible Low-Taxed Income, states that an entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or to provide for the tax expense related to GILTI in the year the tax is incurred as a period expense only. The Company has elected to account for GILTI in the year it is incurred.

15.SEGMENT DATA

The Company operates principally in two business segments: site leasing and site development.

operations. The site leasing segment includes results of the managed and sublease businesses. The site development segment includes the results of both consulting and construction related activities. The Company’s Chief Operating Decision Maker utilizes segment operating profit and operating income as his two measures of segment profit in assessing performance and allocating resources at the reportable segment level. The Company has applied the aggregation criteria to operations within the international site leasing segment on a basis that is consistent with management’s review of information and performance evaluations of the individual markets in this region. Revenues, cost of revenues (exclusive of depreciation, accretion and amortization), capital expenditures (including assets acquired through the issuance of shares of the Company’s Class A common stock) and identifiable assets pertaining to the segments in which the Company continues to operate are presented below.

16.EARNINGS PER SHARE

Basic earnings per share was computed by dividing net income attributable to SBA Communications Corporation by the weighted-average number of shares of Class A common stock outstanding for each respective period. Diluted earnings per share was calculated by dividing net income attributable to SBA Communications Corporation by the weighted-average number of shares of Class A common stock outstanding adjusted for any dilutive Class A common stock equivalents, including unvested RSUs, PSUs, and shares issuable upon exercise of stock options as determined under the “Treasury Stock” method.

The following table sets forth basic and diluted net income per common share attributable to common shareholders for the years ended December 31, 2023, 2022, and 2021 (in thousands, except per share data):

20.REDEEMABLE NONCONTROLLING INTERESTS

The Company allocates income and losses to its redeemable noncontrolling interest holders based on the applicable membership interest percentage. At each reporting period, the redeemable noncontrolling interest is recognized at the greater of (1) the initial carrying amount of the noncontrolling interest as adjusted for accumulated income or loss attributable to the noncontrolling interest holder or (2) the redemption value as of the balance sheet date. Adjustments to the carrying amount of redeemable noncontrolling interest are charged against retained earnings (or additional paid-in capital if there are no retained earnings). The fair value of the redeemable noncontrolling interest is estimated using Level 3 inputs.

21.DERIVATIVES AND HEDGING ACTIVITIES

The Company enters into interest rate swaps to hedge the future interest expense from variable rate debt and reduce the Company’s exposure to fluctuations in interest rates. On August 4, 2020, the Company, through its wholly owned subsidiary, SBA Senior Finance II, terminated an existing $1.95 billion cash flow hedge on a portion of its 2018 Term Loan in exchange for a payment of $176.2 million. On the same date, the Company entered into an interest rate swap which swapped $1.95 billion of notional value accruing interest at one month LIBOR plus 175 basis points for an all-in fixed rate of 1.874% per annum through the maturity date of the 2018 Term Loan. The Company designated this interest rate swap as a cash flow hedge as it is expected to be highly effective at offsetting changes in cash flows of the LIBOR based component interest payments of its 2018 Term Loan.

On August 4, 2020, the Company also terminated its existing interest rate swaps, which were previously de-designated as cash flow hedges. There was no cash transferred in connection with the termination of these swaps. The Company reclassifies the fair value of its interest rate swaps recorded in Accumulated other comprehensive loss, net on their de-designation date to non-cash interest expense on the Consolidated Statements of Operations over their respective remaining term end dates which range from 2023 to 2025.

In order to transition from LIBOR to Term SOFR as a result of Reference Rate Reform, on June 21, 2023, the Company, through its wholly owned subsidiary, SBA Senior Finance II, amended its existing interest rate swap agreement which swapped $1.95 billion of notional value accruing interest at one month Term SOFR plus 185 basis points (inclusive of a CSA of 0.10%) for an all-in fixed rate of 1.900% per annum from August 1, 2023 through January 25, 2024 (the repayment date of the 2018 Term Loan and issuance date of the 2024 Term Loan). The swap will remain in effect under the 2024 Term Loan and will swap $1.95 billion of notional value accruing interest at one month Term SOFR plus 200 basis points for an all-in fixed rate of 2.050% per annum through March 31, 2025. The Company concluded that the amendment to the interest rate swap qualifies for the relief provided by ASU 2021-01 and ASU 2022- 06 and as such, did not de-designate its cash flow hedge. Refer to Note 2 for further discussion of the expedient adopted under ASU 2021-01 and ASU 2022-06.

On November 3, 2023, the Company, through its wholly owned subsidiary, SBA Senior Finance II, entered into a forward-starting interest rate swap agreement which will swap $1.0 billion of notional value accruing interest at one month Term SOFR plus 200 basis points for an all-in fixed rate of 5.830% per annum. The swap has an effective start date of March 31, 2025 and a maturity date of April 11, 2028. The Company designated this interest rate swap as a cash flow hedge as it is expected to be highly effective at offsetting changes in cash flows of the SOFR based component interest payments of its 2024 Term Loan.

As of December 31, 2023, the hedges remain highly effective; therefore, changes in fair value are recorded in Accumulated other comprehensive loss, net. The table below outlines the effects of the Company’s interest rate swaps on the Consolidated Balance Sheets as of December 31, 2023 and 2022.
