PART I

Item 1. Business.

The Company

Uniti Group Inc. (the “Company”, “Uniti”, “we”, “us” or “our”) was incorporated in the state of Delaware in February 2014 and reorganized in the state of Maryland on September 4, 2014. Uniti is an independent, internally managed real estate investment trust (“REIT”) engaged in the acquisition and construction of mission critical infrastructure in the communications industry. We are principally focused on acquiring and constructing fiber optic broadband networks, wireless communications towers, copper and coaxial broadband networks and data centers.

On April 24, 2015, we were separated and spun-off (the “Spin-Off”) from Windstream Holdings, Inc. (“Windstream Holdings” and together with its subsidiaries, “Windstream”) pursuant to which Windstream contributed certain telecommunications network assets, including fiber and copper networks and other real estate (the “Distribution Systems”) and a small consumer competitive local exchange carrier (“CLEC”) business (the “Consumer CLEC Business”) to Uniti and Uniti issued common stock and indebtedness and paid cash obtained from borrowings under Uniti’s senior credit facilities to Windstream. In connection with the Spin-Off, we entered into a long-term exclusive triple-net lease (the “Master Lease”) with Windstream, pursuant to which we lease the Distribution Systems back to Windstream.

Uniti operates as a REIT for U.S. federal income tax purposes. As a REIT, the Company is generally not subject to U.S. federal income taxes on income generated by its REIT operations, which includes income derived from the Master Lease.  We have elected to treat the subsidiaries through which we operate Uniti Fiber and Consumer CLEC Business as taxable REIT subsidiaries (“TRSs”).  TRSs enable us to engage in activities that do not result in income that would be qualifying income for a REIT.  Our TRSs are subject to U.S. federal, state and local corporate income taxes.

The Company operates through a customary up-REIT structure, pursuant to which we hold substantially all of our assets through a partnership, Uniti Group LP, a Delaware limited partnership (the “Operating Partnership”), that we control as general partner. The only significant difference between the financial position and results of operations of the Operating Partnership and its subsidiaries compared to the consolidated financial position and consolidated results of operations of Uniti is that the results for the Operating Partnership and its subsidiaries do not include the Consumer CLEC Business, which is operated through Talk America Services, LLC (“Talk America”), a direct, wholly-owned subsidiary of Uniti. This structure is intended to facilitate future acquisition opportunities by providing the Company with the ability to use common units of the Operating Partnership as a tax-efficient acquisition currency. As of December 31, 2017, we are the sole general partner of the Operating Partnership and own approximately 97.7% of the partnership interests in the Operating Partnership.

For the year ended December 31, 2017, we had revenues of $916.0 million, net loss attributable to common shareholders of $16.6 million, Funds From Operations (“FFO”) of $352.5 million and Adjusted Funds From Operations (“AFFO”) of $424.8 million. Both FFO and AFFO are non-GAAP financial measures, which we use to analyze our results. Refer to Part II, Item 7 Management’s Discussion and Analysis of Financial Condition and Results of Operations, of this Annual Report for additional information regarding these non-GAAP measures. As of December 31, 2017, we managed our operations in four reportable business segments, which are described in more detail in Note 13 to our consolidated financial statements contained in Part II, Item 8 Financial Statements and Supplementary Data.

Business

We are an independent, internally-managed REIT engaged in the acquisition and construction of mission critical infrastructure in the communications industry. We manage our operations in four separate lines of business: Uniti Fiber, Uniti Towers, Uniti Leasing and Talk America.

Table of Contents

Uniti Fiber

Uniti Fiber is a leading provider of infrastructure solutions, including cell site backhaul and small cell for wireless operators and Ethernet, wavelengths and dark fiber for telecommunications carriers and enterprises. With Uniti Fiber, our goal is to capitalize on the rising demand by carriers and enterprises for dark fiber, establish ourselves as a proven small-cell systems provider and leverage wholesale enterprise opportunities as well as opportunities through the School and Libraries Program (commonly referred to as E-Rate) administered by the Universal Service Administrative Company. We believe Uniti Fiber is the mission-critical focal point in the modern communications infrastructure industry and will accelerate our growth and diversification strategy and expand our relationships with high quality national and international wireless carriers.  

On July 3, 2017, we acquired Southern Light and Hunt. Southern Light is a provider of data transport services along the Gulf Coast region serving twelve attractive Tier II and Tier III markets across Florida, Alabama, Louisiana, and Mississippi, and Hunt is a provider of data transport to K-12 schools and government agencies with a dense fiber network in Louisiana.  These acquisitions allow us to scale our products and capacity with wireless carriers, enterprise, wholesale, and E-Rate customers across a significantly expanded Uniti Fiber network.

At December 31, 2017, Uniti Fiber’s revenues under contract were over $1.3 billion, with a network consisting of 1.4 million strand miles of fiber and approximately 16,750 customer connections.  Results for Uniti Fiber are reported in our consolidated financial statements in our Fiber Infrastructure business segment.

Uniti Towers

The strategy of Uniti Towers is to acquire and construct tower and tower-related real estate in the United States and Latin America. We are focused on markets with strong macroeconomic fundamentals, politically stable environments and strong underlying communications growth trends. Specifically, our focus is on markets where numerous investment grade carriers operate and there is strong communications infrastructure potential due to underpenetrated 5G, 4G or even 3G technology.  Uniti Towers also provides build-to-suit opportunities using customized master lease agreements designed for long-term carrier partnerships. We believe that our strategy of focusing on fiber and towers in the United States and Latin America through Uniti Fiber and Uniti Towers is highly synergistic and will drive incremental growth opportunities.

On January 31, 2017, Uniti Towers completed the acquisition of Network Management Holdings LTD (“NMS”).  At close, NMS owned and operated 366 wireless communications towers across Mexico, Colombia, and Nicaragua.

At December 31, 2017, the Uniti Towers’ portfolio consisted of 227 wireless communications towers located in 20 states across the eastern and central United States and 440 wireless communications towers in Latin America.  Results for Uniti Towers are reported in our consolidated financial statements in our Towers business segment.

Uniti Leasing

Uniti Leasing is engaged in acquiring mission-critical communications assets, such as fiber, data centers, next-generation consumer broadband, coaxial and upgradeable copper, and leasing them back to anchor customers on either an exclusive or shared-tenant basis.   Presently, Uniti Leasing’s primary source of revenue is rental revenues from leasing the Distribution Systems to Windstream under the Master Lease.  We believe our attractive cost of capital and advantaged REIT structure will enable Uniti Leasing to provide creative and tax-efficient solutions to additional customers, including (i) sale leaseback transactions, whereby Uniti Leasing acquires existing infrastructure assets from communications service providers and leases them back on a long-term basis; (ii) capital investment financing, whereby Uniti Leasing offers communications service providers a cost-efficient method of raising funds for discrete capital investments to upgrade or expand their network; and (iii) mergers and acquisitions financing, whereby Uniti Leasing facilitates mergers and acquisition transactions as a capital partner.  Results for Uniti Leasing are reported in our consolidated financial statements in our Leasing business segment.

Talk America

Table of Contents

We conduct the Consumer CLEC Business through Talk America Services, LLC. Talk America provides local telephone, high-speed Internet and long distance service to approximately 28,500 customers principally located in 17 states across the eastern and central United States. Substantially all of the network assets used to provide these services to customers are contracted through interconnection agreements with other telecommunications carriers.  Results for Talk America are reported in our in our consolidated financial statements in our Consumer CLEC business segment.

Industry

The current communications infrastructure industry is marked by the growing demand for and use of bandwidth-intensive devices and applications, such as smart devices, real-time and online streaming video, cloud-based applications, social media and mobile broadband. This growth in consumption requires the support of robust communications infrastructure, of which fiber networks and communications towers are critical components. Substantial investments have been made in recent years in fiber networks, lit services and colocation facilities to keep pace with the increased bandwidth use of both enterprise- and consumer-end users. As companies attempt to keep pace with this rapidly evolving business sector, communications infrastructure continues to increase in priority and economic importance. We believe this considerable demand creates tremendous opportunities for us as an acquirer and operator and as a funding source for operators seeking to capitalize on these trends through build outs and acquisitions of infrastructure assets.

The wireless communications industry is a prime example of the growing importance of the bandwidth infrastructure industry. As wireless traffic and mobile data consumption continue to grow worldwide, participants in the wireless communications industry are increasing their network capacity through the development of new wireless cell sites and the addition of bandwidth capacity.  Consumers are demanding network quality and coverage, and as a result wireless carriers are making significant capital investments to improve quality, expand their coverage and remain relevant in a highly competitive industry. We expect this continued growth in capital expenditures to generate high demands for wireless towers (including strong growth in long-term tower leasing), tower space and bandwidth infrastructure services.

Strategy

Our primary goal is to create long-term stockholder value by (i) generating reliable and growing cash flows, (ii) diversifying our tenant and asset base, (iii) paying a consistent dividend, and (iv) maintaining our financial strength and liquidity. To achieve this goal, we employ a business strategy that leverages our first mover advantages in the sector and our strong access to the capital markets. The key components of our business strategy are:

Acquire Additional Infrastructure Assets Through Sale Leaseback Transactions

We are actively seeking to acquire communications infrastructure assets from communication service providers and lease these assets back to the communication service providers on a long-term basis. We believe this type of transaction benefits the communication service providers with incremental liquidity which can be used to reduce indebtedness or for other investments, while they continue to focus on their existing business. We will employ a disciplined, opportunistic acquisition strategy and seek to price transactions appropriately based on, among other things, growth opportunities, the mix of assets acquired, length and terms of the lease, and credit worthiness of the tenant.

This strategy will also expand our mix of tenants and other real property and will reduce our revenue concentration with Windstream. We expect that this objective will be achieved over time as part of our overall strategy to acquire new distribution systems and other real property within the communications infrastructure industry to further diversify our overall portfolio.

Capitalize on the Market Demand for Increased Bandwidth Infrastructure and Performance

Bandwidth intensive devices and applications are rapidly fueling worldwide consumption of bandwidth, which in turn fuels a continuously growing demand for stable and secure bandwidth.  Communications service providers and other enterprises whose services and businesses require substantial amounts of bandwidth are increasingly looking

7

Table of Contents

to infrastructure providers to support their bandwidth needs and to expand the reach, performance and security of their networks.  We believe Uniti Fiber is well positioned to capitalize on this ongoing demand for bandwidth infrastructure solutions.  

Fund Capital Extensions and Improvements of Infrastructure Assets for Existing and New Tenants

We believe the communications infrastructure industry in the United States is currently going through an upgrade cycle driven by the consumer’s general desire for greater bandwidth and wireless services. These upgrades require significant capital expenditures, and we believe Uniti provides an attractive, non-competitive funding source for communication service providers to help accelerate the expansion of their networks at an attractive cost of capital.

We intend to support our tenant operators and other communication service providers by providing capital to them for a variety of purposes, including capacity augmentation projects, tower construction and network expansions. We expect to structure these investments as lease arrangements that produce additional rents.

Facilitate M&A Transactions in the Communication Service Sector as a Capital Partner

We believe Uniti can provide cost efficient funds to potential acquirors in the communication service sector, and thereby facilitate M&A transactions as a capital partner. The highly fragmented nature of the communication service sector is expected to result in more consolidation, which we believe will provide us ample opportunity to pursue these types of transactions.

Maintain Balance Sheet Strength and Liquidity

We seek to maintain a capital structure that provides the resources and financial flexibility to position us to capitalize on strategic growth opportunities. Our access to, and cost of, external capital is dependent on various factors, including general market conditions, credit ratings on our securities, interest rates and expectations of our future business performance. We intend to maintain a strong balance sheet through disciplined use of leverage, aiming to lower our relative cost of capital over time, and continuing to have access to multiple sources of capital and liquidity. As of December 31, 2017, we had $59.8 million of unrestricted cash and cash equivalents, and $470 million of undrawn borrowing capacity under our revolving credit facility. All of our debt is either fixed-rate debt, or floating-rate debt that we have fixed through the use of interest rate swaps.

Competition

We compete for investments in the communications industry with telecommunications companies, investment companies, private equity funds, hedge fund investors, sovereign funds and other REITs who focus primarily on specific segments of the communications infrastructure industry. The communications infrastructure industry is characterized by a high degree of competition among a large number of participants, including many local, regional and global corporations.  Some of our competitors are significantly larger and have greater financial resources and lower costs of capital than we have. In addition, revenues from our network properties are dependent, to an extent, on the ability of our operating partners, like Windstream, to compete with other communication service providers.

However, we believe we are positioned to identify and successfully capitalize on acquisition opportunities that meet our investment objectives and that we have significant competitive advantages that support our leadership position in owning, funding the construction of and leasing communications infrastructure, including:

First-Mover Advantage; Uniquely Positioned to Capitalize on Expansion Opportunities

We are the first and only REIT primarily focused on the acquisition and construction of mission critical infrastructure in the communications industry. We believe this provides us with a significant first-mover competitive advantage to capitalize on the large and fragmented communications infrastructure industry. Additionally, we believe our position, scale and national reach will help us achieve operational efficiencies and support future growth opportunities.

Large Scale Anchor Tenant; Stable Rent Revenues

We believe the assets we lease to Windstream under the Master Lease are critical for Windstream to successfully run its business and operations. Windstream, as our anchor tenant, provides us with a base of stable and highly predictable rent revenues as an initial platform for us to grow and diversify our portfolio and tenant base.

Windstream is a publicly-traded company that provides advanced network communications, including cloud computing and managed services, to businesses nationwide. Windstream also offers broadband, phone and digital TV services to consumers primarily in rural areas. Windstream continues to operate the Distribution Systems, hold the associated regulatory licenses and own and operate other assets, including distribution systems in select states not included in the Spin-Off.

Windstream has a diverse customer base, encompassing enterprise and small business customers, carriers and consumers. The Distribution Systems we lease to Windstream are located in 29 different states across the continental United States. The fiber assets in any one state do not account for more than 20% of the total route miles in our network. We believe this geographic diversification will limit the effect of changes in any one market on our overall performance.

Windstream is subject to the reporting requirements of the SEC, which include the requirements to file annual reports containing audited financial information and quarterly reports containing unaudited financial information. Windstream’s filings with the SEC can be found at www.sec.gov. Windstream’s filings are not incorporated by reference into this Annual Report.

Strong Relationships with Communication Service Providers

Members of our management team have developed an extensive network of relationships with qualified local, regional and national communication service providers across the United States. This extensive network has been built by our management team through decades of operating experience, involvement in industry trade organizations and the development of banking relationships and investor relations within the communications infrastructure industry. We believe these strong relationships will allow us to effectively source investment opportunities from communication service providers other than Windstream. We intend to work collaboratively with our operating partners in providing expansion capital at attractive rates to help them achieve their growth and business objectives. We will seek to partner with communication service providers who possess local market knowledge, demonstrate hands-on management and have proven track records.

Experienced and Committed Management Team

Our senior management team is comprised of veteran leaders with strong backgrounds in their respective disciplines. As a result of extensive public company experience, our senior management team has over 100 years of combined experience in managing telecommunications operations, consummating mergers and acquisitions and accessing both debt and equity capital markets to fund growth and maintain a flexible capital structure.

Insurance

We maintain, or will require in our leases, including the Master Lease, that our tenants maintain, all applicable lines of insurance on our properties and their operations. Under the Master Lease, Windstream has the right to self-insure or use a captive provider with respect to its insurance obligations. We believe that the amount and scope of insurance coverage provided by our policies and the policies maintained by our tenants are customary for similarly situated companies in the telecommunications industry. However, our tenants may elect not to, or be able to, maintain the required insurance coverages, and the failure by any of them to do so could have a material adverse effect on us. We may not continue to require the same levels of insurance coverage under our leases, including the Master Lease, and such insurance may not be available at a reasonable cost in the future or fully cover all losses on our properties upon the occurrence of a catastrophic event.  Moreover, we cannot guarantee the future financial viability of the insurers.

Employees

At December 31, 2017, we had 654 full-time employees. Except for 18 employees in Mexico, none of our employees are subject to a collective bargaining agreement.

Significant Customers

For the years ended December 31, 2017 and 2016 and for the period from April 24, 2015 to December 31, 2015, 74.8%, 87.9% and 96.3% of our revenues, respectively, were derived from leasing our Distribution Systems to Windstream Holdings pursuant to the Master Lease.  

Government Regulation, Licensing and Enforcement

U.S. Telecommunications Regulatory Overview

Market Overview

Our subsidiaries and our tenants operate in a regulated and highly competitive market.  Current and potential competitors include other communications tower owners, providers of voice and data services, providers of fiber and other backhaul services, traditional telephone companies, cable companies, Internet service providers, and other companies. As operators of telecommunications facilities and services, both we and the current and future tenants of our telecommunications assets are typically subject to extensive and complex federal, state and local telecommunications laws and regulations. The Federal Communications Commission (“FCC”) regulates the provision of interstate and international telecommunications services, and state public utility commissions (“PUCs”) regulate intrastate telecommunications services. Both FCC and PUC telecommunications regulations are wide-ranging and can subject us and our tenants to civil, criminal and administrative sanctions. We expect that the telecommunications industry, in general, will continue to face increased competition and regulation. Changes in laws and regulations and regulatory non-compliance by us or our tenants could have a significant direct or indirect effect on our operations and financial condition, as detailed below and set forth under “Risk Factors—Risks Related to Our Business.”

Our operations require that certain of our subsidiaries hold licenses or other forms of authorization from the FCC and state PUCs in those states where we operate, and in some jurisdictions our subsidiaries must file tariffs or other price lists describing their rates, terms and conditions of the services they provide.  The FCC and PUCs can modify or terminate a service provider’s license or other authority to provide telecommunications services for failure to comply with applicable laws and regulations.  The FCC and PUCs may also investigate our subsidiaries’ operations and may impose fines or other penalties for violations of the same.  In addition, our subsidiaries are required to submit periodic reports to the FCC and PUCs documenting their revenues and other data.  Some of this information is used as the basis for the imposition of various regulatory fees and other assessments. In order to engage in certain transactions in some jurisdictions, including changes of control, the encumbrance of certain assets, the issuance of securities, the incurrence of indebtedness, the guarantee of indebtedness of other entities, including subsidiaries of ours, and the transfer of our assets, we are required to provide notice and/or obtain prior approval from certain governmental agencies.  

Our subsidiaries are subject to a number of federal and state regulations that govern the way we can conduct our business.  Such regulations also impose certain operating costs on our businesses.  These regulations can include restrictions on pricing flexibility for certain products, minimum service quality standards, service reporting, intercarrier compensation, universal service funding, and other obligations.  

We believe that we have structured the operations for our core real estate business in a manner that will not require us to become regulated as a public utility or common carrier by the FCC or PUCs.  But, a number of our business operations nonetheless are subject to federal, state, and local regulation.

Consumer CLEC Business

10

Table of Contents

Talk America Services operates the Consumer CLEC Business as a reseller of telecommunication services pursuant to a Wholesale Master Services Agreement and a Master Service Agreement with Windstream.  In almost all cases, Windstream does not own the underlying telecommunication facilities required to support the Consumer CLEC Business, rather it is a reseller of facility-based services pursuant to wholesale interconnection agreements with third-party carriers that own the underlying telecommunication facilities. Talk America Services is authorized and regulated as a CLEC and an interexchange (long-distance) service provider in most states where it has Consumer CLEC Business customers. These certifications subject Talk America Services to regulations requiring it to file and maintain tariffs for the rates charged to its Consumer CLEC Business customers for regulated services and to comply with service quality, service reporting and other regulatory obligations. Talk America Service’s ability to operate the Consumer CLEC Business is dependent on existing telecommunication regulations that allow access to such underlying facilities of other carriers at reasonable rates.

With respect to the broadband Internet services that we provide, traditionally, the FCC has recognized that broadband Internet access services are “information services” subject to limited regulation. In 2015, the FCC issued a “network neutrality” decision that declared broadband Internet access services to be subject to certain “telecommunications services” regulation under Title II of the Communications Act of 1934. This decision creates uncertainty concerning the level of regulation that will apply to broadband services going forward. These regulations will limit the ways that broadband Internet access service providers can structure business arrangements and manage their networks and could spur additional restrictions, including rate regulation, which could adversely affect broadband investment and innovation. The proper scope of such regulations is being debated in Congress and may be revisited by the FCC. It is unclear at this time how broadband services will be regulated in the future, and the potential impact those regulations may have on our broadband Internet service business.

Uniti Towers

Uniti Towers is subject to international, federal, state and local regulatory requirements with respect to the registration, siting, construction, lighting, marking and maintenance of our towers. In the United States, the construction of new towers or modifications to existing towers may require pre-approval by the FCC and the Federal Aviation Administration (“FAA”), depending on factors such as tower height and proximity to public airfields. Towers requiring pre-approval must be registered with the FCC and maintained in accordance with FCC and FAA standards. Similar requirements regarding pre-approval of the construction and modification of towers are imposed by regulators in other countries where Uniti Towers owns and operates towers. Non-compliance with applicable tower-related requirements may lead to monetary penalties or site deconstruction orders.

Regulatory regimes outside of the U.S. and its territories vary by country and locality; however, these regulations typically require 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. 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.

In all countries where Uniti Towers operates, it is subject to zoning restrictions and restrictive covenants imposed by local authorities or community organizations. While these regulations vary, they typically require approval from local authorities or community standards organizations prior to tower construction or the addition of a new antenna to an existing tower. Opposition by local zoning authorities and community residents can delay or prevent new tower construction or site upgrade projects, thereby increasing the costs and timing of new tower construction and modifications or site upgrades.

The failure to properly maintain towers pursuant to applicable regulatory requirements, such as but not limited to, lighting, painting, and other safety standards, can subject us to significant enforcement actions, including monetary penalties both within the U.S. and abroad.

Uniti Fiber

11

Table of Contents

Our subsidiaries that compose Uniti Fiber own and operate significant fiber and other communications backhaul facilities throughout various regions of the U.S.  The provision of such services is subject to FCC and PUC licensure in many jurisdictions, and the companies are typically licensed as CLECs and/or interexchange carriers in those states where they operate.  The companies also hold various FCC wireless licenses in order to provide microwave backhaul services.  Because of the nature of the licenses that these companies hold, and the nature of the services that they provide, they are subject to various federal and state regulatory requirements, including, but not limited to, revenue and other reporting requirements and tariffing requirements.  The companies must also maintain their wireless licenses with the FCC, which requires construction and notification reporting and other regulatory requirements.  The construction of additions to our current fiber network through our Uniti Fiber subsidiary is also subject to certain state and local governmental permitting and licensing requirements  

Regulatory Changes

Future revenues, costs and capital investment in the communication businesses of our tenants, Talk America Services, Uniti Fiber, Uniti Towers, and other related entities could be adversely affected by material changes to, or decisions regarding applicability of, government requirements, including, but not limited to, changes in rules governing inter-carrier compensation, interconnection access to network facilities, state and federal universal service fund (“USF”) support, rules governing the prices that can be charged for business data services, infrastructure location and siting rules, and other requirements.  Federal and state communications laws may be amended in the future, and other laws may affect our business.  In addition, certain laws and regulations applicable to us and our competitors may be, and have been, challenged in the courts and could be changed at any time. We cannot predict future developments or changes to the regulatory environment or the impact such developments or changes would have on our business.

In addition, regulations could create significant compliance costs for us.  Delays in obtaining FCC and PUC certifications and regulatory approvals could cause us to incur substantial legal and administrative expenses, and conditions imposed in connection with such approvals could adversely affect the rates that we are able to charge our customers. Both our subsidiaries and our tenants may also be affected by legislation and/or regulation imposing new or additional obligations related to, for example, law enforcement assistance, cyber-security protection, intellectual property rights protections, environmental protections, consumer privacy, tax, or other areas.  We can’t predict how any such future changes may impact our business, or the business of our tenants.

Environmental Matters

A wide variety of federal, state and local environmental and occupational health and safety laws and regulations affect telecommunications operations and facilities. These complex laws, and their enforcement, involve a myriad of regulations, many of which involve strict liability. Some of these federal, state and local laws may directly impact us. Under various federal, state and local environmental laws, ordinances and regulations, an owner of real property, such as us, may be liable for the costs of removal or remediation of hazardous or toxic substances at, under or disposed of in connection with such property, as well as other potential costs relating to hazardous or toxic substances (including government fines and damages for injuries to persons and adjacent property). The cost of any required remediation, removal, fines or personal property damages and the owner’s liability therefore could exceed or impair the value of the property and/or the assets of the owner. In addition, the presence of such substances, or the failure to properly dispose of or remediate such substances, may adversely affect the owner’s ability to sell or rent such property or to borrow using such property as collateral, which, in turn, could reduce revenues.

We are dependent on Windstream Holdings to make payments to us under the Master Lease, and an event that materially and adversely affects Windstream’s business, financial position or results of operations could materially and adversely affect our business, financial position or results of operations.

Windstream is the lessee of the Distribution Systems pursuant to the Master Lease and, therefore, is presently the source of a substantial portion of our revenues. There can be no assurance that Windstream will have sufficient assets, income and access to financing to enable it to satisfy its payment and other obligations under the Master Lease. In recent years, Windstream has experienced annual declines in its total revenue and sales.  Most recently, Windstream has endured a challenge from an entity who acquired certain Windstream debt securities for the purpose of seeking an “event of default” under such securities relating to the Spin-Off.  An actual “event of default” would permit the trustee or holders of at least 25% in aggregate principal amount of outstanding of such Windstream debt securities to declare the principal amount of all outstanding Windstream debt to be immediately due and payable. Such an outcome would trigger cross-default provisions in Windstream’s other debt instruments, including Windstream’s existing credit facility, which, in turn, would trigger a default under the Master Lease. A default by Windstream under the Master Lease could materially adversely affect our business, assets, financial position, and results of operations, including our ability to pay dividends to our stockholders as required to maintain our status as a REIT.

If the Spin-Off, together with certain related transactions, fails to qualify as a tax-free transaction for U.S. federal income tax purposes, both we and Windstream could be subject to significant tax liabilities and, in certain circumstances, we could be required to indemnify Windstream for material taxes pursuant to indemnification obligations under the tax matters agreement entered into in connection with the Spin-Off.

Windstream received a private letter ruling (the “IRS Ruling”) from the Internal Revenue Service (the “IRS”) to the effect that, on the basis of certain facts presented and representations and assumptions set forth in the request submitted to the IRS, the Spin-Off will qualify as tax-free under Sections 355 and 368(a)(1)(D) of the Internal Revenue Code of 1986, as amended (the “Code”). Although a private letter ruling from the IRS generally is binding on the IRS, if the factual representations and assumptions made in the letter ruling request are untrue or incomplete in any material respect, then Windstream will not be able to rely on the IRS Ruling. In addition, the IRS Ruling does not address certain requirements for tax-free treatment of the Spin-Off under Sections 355 and 368(a)(1)(D) of the Code and Windstream’s use of Uniti indebtedness and common stock to retire certain of Windstream’s indebtedness (the “debt exchanges”). Accordingly, the Spin-Off was conditioned upon the receipt by Windstream of a tax opinion from its counsel with respect to the requirements on which the IRS did not rule, which concluded that such requirements also should be satisfied. The tax opinion was based on, among other things, the IRS Ruling, then current law and certain representations and assumptions as to factual matters made by Windstream and us. Any change in currently applicable law, which may or may not be retroactive, or the failure of any factual representation or assumption to be true, correct and complete in all material respects, could adversely affect the conclusions reached in the tax opinion. In addition, the tax opinion is not binding on the IRS or the courts, and the IRS or the courts may not agree with the tax opinion.

If the Spin-Off were determined to be taxable, Windstream would recognize taxable gain. Under the terms of the tax matters agreement entered into with Windstream in connection with the Spin-Off (the “Tax Matters Agreement”), we are generally responsible for any taxes imposed on Windstream that arise from the failure of the Spin-Off and the debt exchanges to qualify as tax-free for U.S. federal income tax purposes, within the meaning of Section 355 and Section 368(a)(1)(D) of the Code, as applicable, to the extent such failure to qualify is attributable to certain actions, events or transactions relating to our stock, indebtedness, assets or business, or a breach of the relevant representations or any covenants made by us in the Tax Matters Agreement, the materials submitted to the IRS in

connection with the request for the IRS Ruling or the representations provided in connection with the tax opinion. Our indemnification obligations to Windstream are not limited by any maximum amount and such amounts could be substantial. If we are required to indemnify Windstream under the circumstances set forth in the Tax Matters Agreement, we may also be subject to substantial tax liabilities.

In addition, if the Spin-Off or the debt exchanges failed to qualify as tax free for U.S. federal income tax purposes, Windstream may incur significant tax liabilities that could materially affect Windstream’s ability to make payments under the Master Lease.

Our level of indebtedness could materially and adversely affect our financial position, including reducing funds available for other business purposes and reducing our operational flexibility.

As of December 31, 2017, we had outstanding long term indebtedness of approximately $4.5 billion consisting of a combination of senior notes and term loans. Additionally, we have a revolving credit facility in an aggregate principal amount of up to $750 million, $470 million of which was undrawn as of December 31, 2017, provided by a syndicate of banks and other financial institutions. Subject to the restrictions set forth in our debt agreements, our board of directors may establish and change our leverage policy at any time without stockholder approval. Any significant additional indebtedness could require a substantial portion of our cash flow to make interest and principal payments due on our indebtedness. Greater demands on our cash resources may reduce funds available to us to pay dividends, make capital expenditures and acquisitions, or carry out other aspects of our business strategy. Increased indebtedness can also limit our ability to adjust rapidly to changing market conditions, make us more vulnerable to general adverse economic and industry conditions and create competitive disadvantages for us compared to other companies with relatively lower debt levels. Increased future debt service obligations may limit our operational flexibility, including our ability to acquire assets, finance or refinance our assets or sell assets as needed.

We intend to pursue acquisitions of additional properties and seek other strategic opportunities, which may result in the use of a significant amount of management resources or significant costs, and we may not fully realize the potential benefits of such transactions.

We intend to pursue acquisitions of additional properties and seek acquisitions and other strategic opportunities. Accordingly, we currently are, and expect in the future to be, engaged in evaluating potential transactions and other strategic alternatives. Although there is uncertainty that any of these discussions will result in definitive agreements or the completion of any transaction, we may devote a significant amount of our management resources to such a transaction, which could negatively impact our operations. We may incur significant costs in connection with seeking acquisitions or other strategic opportunities regardless of whether the transaction is completed. In the event that we consummate an acquisition or strategic alternative in the future, there is no assurance that we would fully realize the potential benefits of such a transaction. Integration may be difficult and unpredictable, and acquisition-related integration costs, including certain non-recurring charges, could materially and adversely affect our results of operations. Moreover, integrating assets and businesses may significantly burden management and internal resources, including the potential loss or unavailability of key personnel. If we fail to successfully integrate the assets and businesses we acquire, we may not fully realize the potential benefits we expect, and our operating results could be adversely affected.

Risks Related to the Status of Uniti as a REIT

If we do not qualify as a REIT, or fail to remain qualified as a REIT, we will be subject to U.S. federal income tax as a regular corporation and could face a substantial tax liability, which could reduce the amount of cash available for distribution to our stockholders and to service debt.

We operate as a REIT for U.S. federal income tax purposes.  Our qualification as a REIT will depend on our satisfaction of certain highly technical and complex asset, income, organizational, distribution, stockholder 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 may not obtain independent appraisals.

14

Table of Contents

If we were to fail to qualify as a REIT in any taxable year, we would be subject to U.S. federal income tax on our taxable income at regular corporate rates, including any applicable alternative minimum tax, and dividends paid to our stockholders would not be deductible by us in computing our taxable income. Any resulting corporate liability could be substantial and could reduce the amount of cash available for distribution to our stockholders, which in turn could have an adverse impact on the value of our common stock and to service debt. Unless we were entitled to relief under certain Code provisions, we also would be disqualified from reelecting to be taxed as a REIT for the four taxable years following the year in which we failed to qualify as a REIT.

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

The rules dealing with federal income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Department of the Treasury (“Treasury”). Changes to the tax laws affecting REITs or TRSs, which may have retroactive application, could adversely affect our stockholders or us. We cannot predict how changes in the tax laws might affect our stockholders or us. Accordingly, we cannot provide assurance that new legislation, Treasury regulations, administrative interpretations or court decisions will not significantly affect our ability to remain qualified as a REIT, the federal income tax consequences of such qualification, the determination of the amount of REIT taxable income or the amount of tax paid by the TRSs.

We could fail to qualify as a REIT if income we receive from Windstream is not treated as qualifying income.

Under applicable provisions of the Code, we will not be treated as a REIT unless we satisfy various requirements, including requirements relating to the sources of our gross income. Rents received or accrued by us from Windstream will not be treated as qualifying rent for purposes of these requirements if the Master Lease is not respected as a true lease for U.S. federal income tax purposes and is instead treated as a service contract, joint venture or some other type of arrangement. If the Master Lease is not respected as a true lease for U.S. federal income tax purposes, we may fail to qualify as a REIT.

REIT distribution requirements could adversely affect our ability to execute our business plan.

We generally must distribute annually at least 90% of our REIT taxable income, determined without regard to the dividends paid deduction and excluding any net capital gains, in order for us to qualify as a REIT (assuming that certain other requirements are also satisfied) so that U.S. federal corporate income tax does not apply to earnings that we distribute. To the extent that we satisfy this distribution requirement and qualify for taxation as a REIT but distribute less than 100% of our REIT taxable income, determined without regard to the dividends paid deduction and excluding any net capital gains, we will be subject to U.S. federal corporate income tax on our undistributed net taxable income. In addition, we will be subject to a 4% nondeductible excise tax if the actual amount that we distribute to our stockholders in a calendar year is less than a minimum amount specified for REITs under U.S. federal income tax laws. We intend to make distributions to our stockholders to comply with the REIT requirements of the Code.

Our FFO is currently generated primarily by rents paid under the Master Lease. From time to time, we may generate 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 could be required to borrow funds on unfavorable terms, sell assets at disadvantageous prices or distribute amounts that would otherwise be invested in future acquisitions in order to make distributions sufficient to enable us to pay out enough of our taxable income to satisfy the REIT distribution requirement and to avoid corporate income tax, including the 4% excise tax in a particular year. These alternatives could increase our costs or reduce our equity. Thus, compliance with the REIT requirements may hinder our ability to grow, which could adversely affect the value of our common stock and decrease cash available to service debt.

Even if we remain qualified as a REIT, we may face other tax liabilities that reduce our cash flow.

Even if we remain qualified for taxation as a REIT, we may be subject to certain U.S. federal, state and local taxes on our income and assets, including taxes on any undistributed income and state or local income, property and

15

Table of Contents

transfer taxes. For example, we hold some of our assets and conduct certain of our activities through a TRS that is subject to U.S. federal, state and local corporate-level income taxes as a regular C corporation. In addition, we may incur a 100% excise tax on transactions with a TRS if they are not conducted on an arm’s-length basis. Any of these taxes could decrease cash available for distribution to our stockholders and servicing our debt.

Complying with the REIT requirements may cause us to forego otherwise attractive acquisition opportunities.

To qualify as a REIT for U.S. federal income tax purposes, 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). The remainder of our investments (other than government securities, qualified real estate assets and securities issued by a TRS) generally cannot 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) can consist of the securities of any one issuer, no more than 20% of the value of our total assets can be represented by securities of one or more TRSs, and no more than 25% of the value of our total assets can be represented by nonqualified publicly offered REIT debt instruments (as defined in the Code). 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 of such asset limitations, we may be required to forego otherwise attractive investments. These actions could have the effect of reducing our income and amounts available for distribution to our stockholders and servicing our debt.

Risks Related to our Business

We are dependent on the communications industry and may be susceptible to the risks associated with it, which could materially adversely affect our business, financial position or results of operations.

As the owner, lessor and provider of communications services and distribution systems serving the communications industry, we are impacted by the risks associated with the communications industry. Therefore, our success is to some degree dependent on the communications industry, which could be adversely affected by economic conditions in general, changes in consumer trends and preferences, changes in communications technology and other factors over which we and our tenants have no control. As we are subject to risks inherent in substantial investments in a single industry, a decrease in the communications business would likely have an adverse effect on our revenues.

Our business is subject to government regulations and changes in current or future laws or regulations could restrict our ability to operate our business in the manner currently contemplated.

Our business, and that of our tenants, is subject to federal, state, local and foreign regulation. In certain jurisdictions these regulations could be applied or enforced retroactively. Local zoning authorities and community organizations are often opposed to construction in their communities and these regulations can delay, prevent or increase the cost of new distribution system construction and modifications, thereby limiting our ability to respond to customer demands and requirements. Existing regulatory policies may materially and adversely affect the associated timing or cost of such projects and additional regulations may be adopted which increase delays or result in additional costs to us, or that prevent such projects in certain locations. These factors could materially and adversely affect our business, results of operations or financial condition. For more information regarding the regulations we are subject to, please see the section entitled “Business – Government Regulation, Licensing and Enforcement.”

Any failure of Uniti Fiber’s physical infrastructure or services could lead to significant costs and disruptions.

Uniti Fiber’s business depends on providing customers with highly reliable service. The services provided are subject to failure resulting from numerous factors, including human error, power loss, improper maintenance, physical or electronic security breaches, fire, earthquake, hurricane, flood and other natural disasters, water damage, the effect of war, terrorism and any related conflicts or similar events worldwide, and sabotage and vandalism. Problems within Uniti Fiber’s networks or facilities, whether within our control or the control of third-party providers, could result in service interruptions or equipment damage. We may not be able to efficiently upgrade or change Uniti Fiber’s networks or facilities to meet new demands without incurring

16

Table of Contents

significant costs that we may not be able to pass on to customers. Given the service guarantees that may be included in Uniti Fiber’s agreements with customers, such disruptions could result in customer credits; however, we cannot assume that customers will accept these credits as compensation in the future, and we may face additional liability or loss of customers.

Uniti Fiber uses franchises, licenses, permits, rights-of-way, conduit leases, fiber agreements, and property leases, which could be canceled or not renewed.

Uniti Fiber must maintain rights-of-way, franchises, and other permits from railroads, utilities, state highway authorities, local governments, transit authorities, and others to operate its fiber network. We cannot be certain that we will be successful in maintaining these rights-of-way agreements or obtaining future agreements on acceptable terms. Some of these agreements are short-term or revocable at will, and we cannot assure you that we will continue to have access to existing rights-of-way after they have expired or terminated. If a material portion of these agreements are terminated or are not renewed, we might be forced to abandon these networks. In order to operate these networks, we must also maintain fiber leases and indefeasible right of use (“IRU”) agreements between Uniti Fiber and both public and private entities, and there is no assurance that we will be able to renew those fiber leases and IRU agreements on favorable terms, or at all. If we are unable to renew those fiber leases and IRU agreements on favorable terms, we may face increased costs or reduced revenues.

In order to expand Uniti Fiber’s network to new locations, we often need to obtain additional rights-of-way, franchises, and other permits. Our failure to obtain these rights in a prompt and cost-effective manner may prevent us from expanding our network, which may be necessary to meet our contractual obligations to our customers and could expose us to liabilities.

If we lose or are unable to renew key real property leases where Uniti Fiber has located networks or facilities, it could adversely affect our services and increase our costs, as we would be required to restructure or move these networks or facilities.

New technologies or changes in a tenant’s business model could make our business less desirable

and result in decreasing revenues.

The development and implementation of new technologies designed to enhance the efficiency of communications distribution systems, including lit fiber networks and wireless equipment, or changes in a tenant’s business model due to such technological changes, could reduce the need for our services, decrease demand for tower space or fiber or reduce previously obtainable lease rates for communications infrastructure. In addition, tenants may allocate less of their budgets to certain types of communications infrastructure, as the industry is trending towards deploying increased capital to the development and implementation of new technologies. Further, a tenant may decide to no longer outsource certain types of communications infrastructure or otherwise change its business model, which would result in a decrease in our revenue. The development and implementation of any of these and similar technologies to any significant degree or changes in a tenant’s business model could have a material adverse effect on our business, results of operations or financial condition.

If we determine that our goodwill has become impaired, we may incur impairment charges, which would negatively impact our operating results.

At December 31, 2017, we had $673.7 million of goodwill on our consolidated balance sheet. Goodwill represents the excess of cost over the fair value of net assets acquired in business combinations. We assess potential impairment of our goodwill at least annually. Impairment may result from significant changes in the manner of use of the acquired assets, negative industry or economic trends and/or significant underperformance relative to historic or projected operating results. Changes in these events and conditions or other assumptions could result in an impairment charge in the future, which could have a significant adverse impact on our reported earnings.  For a discussion of our goodwill impairment testing, see “Critical Accounting Policies-Evaluation of Goodwill Impairment” in Part II, Item 7A-Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Our foreign operations are subject to economic, political and other risks that could materially and adversely affect our results of operations and financial condition.

Our international business operations expose us to potential adverse financial and operational problems not typically experienced in the United States, including:

In addition, many of our tenants in our international operations are subsidiaries of global telecommunications companies. These subsidiaries may not have the explicit or implied financial support of their parent entities. Any of these factors could adversely affect our results of operations and financial condition.

Our continued operation and expansion outside the United States, including in developing countries, increase the risk of violations of applicable anti-corruption in the future.

Our internal policies provide for compliance with all applicable anti-corruption laws, but despite our training and compliance programs, we cannot assure you that our internal control policies and procedures will always protect us from unauthorized, reckless or criminal acts committed by our employees, agents or partners.  A finding that the Company or its affiliates have violated the U.S. Foreign Corrupt Practices Act (“FCPA”) or similar foreign anti-corruption laws may result in severe criminal or civil sanctions, which could disrupt our business and result in a material adverse effect on our reputation, financial condition and results of operations.

We or our tenants may experience uninsured or underinsured losses, which could result in a significant loss of the capital we have invested in a property, decrease anticipated future revenues or cause us to incur unanticipated expenses.

The Master Lease requires, and we expect that new lease agreements that we enter into will require, that the tenant maintain comprehensive insurance and hazard insurance or self-insure its insurance obligations. However, there are certain types of losses, generally of a catastrophic nature, such as earthquakes, hurricanes and floods that may be uninsurable or not economically insurable. Insurance coverage may not be sufficient to pay the full current market value or current replacement cost of a loss. Inflation, changes in ordinances, environmental considerations, and other factors also might make it infeasible to use insurance proceeds to replace the property after such property has been damaged or destroyed. Under such circumstances, the insurance proceeds received might not be adequate to restore the economic position with respect to such property.

In addition, even if damage to our properties is covered by insurance, a disruption of business caused by a casualty event may result in loss of revenue for our tenants or us. Any business interruption insurance may not fully compensate them or us for such loss of revenue. If one of our tenants experiences such a loss, it may be unable to satisfy its payment obligations to us under its lease with us.

We rely on information technology in our operations, and any material failure, inadequacy, interruption or security failure of that technology could harm our business.

We rely on information technology networks and systems, including the Internet, to process, transmit and store electronic information and to manage or support a variety of our business processes, including financial transactions and maintenance of records. We rely on commercially available systems, software, tools and monitoring to provide

18

Table of Contents

security for processing, transmitting and storing confidential information. Although we have taken steps to protect the security of the data maintained in our information systems, it is possible that our security measures will not be able to prevent the systems’ improper functioning, or the improper disclosure of information in the event of cyber-attacks. Physical or electronic break-ins, computer viruses, attacks by hackers and similar security breaches, can create system disruptions, shutdowns or unauthorized disclosure of confidential information. Any failure to maintain proper function, security and availability of our information systems could interrupt our operations, damage our reputation, subject us to liability claims or regulatory penalties and could materially and adversely affect us.

Risks Related to Our Common Stock

We cannot assure you of our ability to pay dividends in the future.

It is expected that our dividend will be $2.40 per share per annum, subject to approval of our board of directors. The qualify as a REIT, the annual dividend must not be less than 90% of our REIT taxable income on an annual basis, determined without regard to the dividends paid deduction and excluding any net capital gains. Our ability to pay dividends may be adversely affected by a number of factors, including the risk factors herein. Dividends will be authorized by our board of directors and declared by us based upon a number of factors, including actual results of operations, restrictions under Maryland law or applicable debt covenants, our financial condition, our taxable income, the annual distribution requirements under the REIT provisions of the Code, our operating expenses and other factors our directors deem relevant. We cannot assure you that we will achieve investment results that will allow us to make a specified level of cash dividends or year-to-year increases in cash dividends in the future.

Furthermore, while we are required to pay dividends in order to maintain our REIT status (as described above under “Risks Related to Our Status as a REIT- REIT distribution requirements could adversely affect our ability to execute our business plan”), we may elect not to maintain our REIT status, in which case we would no longer be required to pay such dividends. Moreover, even if we do maintain our REIT status, after completing various procedural steps, we may elect to comply with the applicable distribution requirements by distributing, under certain circumstances, shares of our common stock in lieu of cash. If we elect not to maintain our REIT status or to satisfy any required distributions in shares of common stock in lieu of cash, such action could negatively affect our business and financial condition as well as the market price of our common stock. No assurance can be given that we will pay any dividends on shares of our common stock in the future.

Our charter restricts the ownership and transfer of our outstanding stock, which may have the effect of delaying, deferring or preventing a transaction or change of control of our company.

In order for us to qualify as a REIT, not more than 50% in value of our outstanding shares of stock may be owned, beneficially or constructively, by five or fewer individuals at any time during the last half of each taxable year after the first year for which we elect to be taxed and qualify as a REIT. Additionally, at least 100 persons must beneficially own our stock during at least 335 days of a taxable year (other than the first taxable year for which we elect to be taxed and qualify as a REIT). Our charter, with certain exceptions, authorizes our board of directors to take such actions as are necessary or advisable to preserve our qualification as a REIT. Our charter also provides that, unless exempted by the board of directors, no person may own more than 9.8% in value or in number, whichever is more restrictive, of the outstanding shares of our common stock or more than 9.8% in value of the aggregate of the outstanding shares of all classes and series of our stock. The constructive ownership rules are complex and may cause shares of stock owned directly or constructively by a group of related individuals or entities to be constructively owned by one individual or entity. These ownership limits could delay or prevent a transaction or a change in control of us that might involve a premium price for shares of our stock or otherwise be in the best interests of our stockholders.

Pursuant to the Separation and Distribution Agreement, Windstream has agreed to indemnify us (including our subsidiaries, directors, officers, employees and agents and certain other related parties) for any liability arising from or relating to legal proceedings involving Windstream's telecommunications business prior to the Spin-Off, and, pursuant to the Master Lease, Windstream has agreed to indemnify us for, among other things, any use, misuse, maintenance or repair by Windstream with respect to the Distribution Systems. Windstream is currently a party to various legal actions and administrative proceedings, including various claims arising in the ordinary course of its telecommunications business, which are subject to the indemnities provided by Windstream to us. While these actions and proceedings are not believed to be material, individually or in the aggregate, the ultimate outcome of these matters cannot be predicted.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following management’s discussion and analysis of financial condition and results of operations describes the principal factors affecting the results of our operations, financial condition, and changes in financial condition, as well as our critical accounting estimates.

Overview

Company Description

Uniti Group Inc. (the “Company”, “Uniti”, “we”, “us” or “our”) is an independent, internally managed real estate investment trust (“REIT”) engaged in the acquisition and construction of mission critical infrastructure in the communications industry. We are principally focused on acquiring and constructing fiber optic broadband networks, wireless communications towers, copper and coaxial broadband networks and data centers.

On April 24, 2015, we were separated and spun-off (the “Spin-Off”) from Windstream Holdings, Inc. (“Windstream Holdings” and together with its subsidiaries, “Windstream”) pursuant to which Windstream contributed certain telecommunications network assets, including fiber and copper networks and other real estate (the “Distribution Systems”) and a small consumer competitive local exchange carrier (“CLEC”) business (the “Consumer CLEC Business”), to Uniti and Uniti issued common stock and indebtedness and paid cash obtained from borrowings under Uniti’s senior credit facilities to Windstream. In connection with the Spin-Off, we entered into a long-term exclusive triple-net lease (the “Master Lease”) with Windstream, pursuant to which a substantial portion of our real property is leased to Windstream and from which substantially all of our leasing revenues are currently derived.

Uniti operates as a REIT for U.S. federal income tax purposes. As a REIT, the Company is generally not subject to U.S. federal income taxes on income generated by its REIT operations, which includes income derived from the Master Lease. We have elected to treat the subsidiaries through which we operate our fiber business, Uniti Fiber, and Talk America Services, LLC, which operates the Consumer CLEC Business (“Talk America”), as taxable REIT subsidiaries (“TRSs”). TRSs enable us to engage in activities that result in income that does not constitute qualifying income for a REIT. Our TRSs are subject to U.S. federal, state and local corporate income taxes.

The Company operates through a customary up-REIT structure, pursuant to which we hold substantially all of our assets through a partnership, Uniti Group LP, a Delaware limited partnership (the “Operating Partnership”), that we control as general partner. This structure is intended to facilitate future acquisition opportunities by providing the Company with the ability to use common units of the Operating Partnership as a tax-efficient acquisition currency. As of the date of this report, we are the sole general partner of the Operating Partnership and own approximately 97.7% of the partnership interests in the Operating Partnership.

We expect to grow and diversify our portfolio and tenant base by pursuing a range of transaction structures with communication service providers, including, (i) sale leaseback transactions, whereby we acquire existing infrastructure assets from third parties, including communication service providers, and lease them back on a long-term triple net basis; (ii) whole company acquisitions, which may include the use of one or more TRSs that are permitted under the tax laws to acquire and operate non-REIT businesses and assets subject to certain limitations; (iii) capital investment financing, whereby we offer communication service providers a cost efficient method of raising funds for discrete capital investments to upgrade or expand their network; and (iv) mergers and acquisitions financing, whereby we facilitate mergers and acquisition transactions as a capital partner.

We manage our operations as four reportable business segments in addition to our corporate operations:

Leasing Segment: Represents our REIT operations and includes the results from our leasing business, Uniti Leasing, which is engaged in the acquisition of mission-critical communications assets and leasing them to anchor customers on either an exclusive or shared-tenant basis.

Fiber Infrastructure Segment: Represents the operations of our fiber business, Uniti Fiber, which is a leading provider of infrastructure solutions, including cell site backhaul and dark fiber, to the telecommunications industry.

Towers Segment: Represents the operations of our towers business, Uniti Towers, through which we acquire and construct tower and tower-related real estate in the United States and Latin America.

Consumer CLEC Segment: Represents the operations of Talk America through which we operate the Consumer CLEC Business, that prior to the Spin-Off was reported as an integrated operation within Windstream. Talk America provides local telephone, high-speed internet and long distance services to customers in the eastern and central United States.

Corporate Operations: Represents our corporate and back office functions. Certain costs and expenses, primarily related to headcount, insurance, professional fees and similar charges, that are directly attributable to operations of our business segments are allocated to the respective segments.  

We evaluate the performance of each segment based on Adjusted EBITDA, which is a segment performance measure we define as net income determined in accordance with GAAP, before interest expense, provision for income taxes, depreciation and amortization, stock-based compensation expense, the impact, which may be recurring in nature, of transaction and integration related expenses, the write off of unamortized deferred financing costs, costs incurred as a result of the early repayment of debt, changes in the fair value of contingent consideration and financial instruments, and other similar items. For more information on Adjusted EBITDA, see “Non-GAAP Financial Measures.” Detailed information about our segments can be found in Note 13 to our consolidated financial statements contained in Part II, Item 8 Financial Statements and Supplementary Data.

Significant Business Developments

Tax Reform.  On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Act”) was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017. We have calculated our best estimate of the impact of the Act in our year end income tax provision in accordance with our understanding of the Act and guidance available as of the date of this filing and as a result have recorded $17.4 million as additional income tax benefit in the fourth quarter of 2017, the period in which the legislation was enacted. The provisional amount relates to the remeasurement of certain deferred tax assets and liabilities, based on the rates at which they are expected to reverse in the future.

Acquisition of Southern Light, LLC. On July 3, 2017, we completed the previously announced acquisition of Southern Light, LLC (“Southern Light”). We acquired all of the outstanding membership interests of Southern Light for approximately $638 million in cash, including the payoff of existing indebtedness and unpaid transaction expenses, and the issuance of 2.5 million common units in the Operating Partnership with an acquisition date fair value of $64.3 million. Southern Light is a leading provider of data transport services along the Gulf Coast region serving twelve attractive Tier II and Tier III markets across Florida, Alabama, Louisiana, and Mississippi. Southern Light’s dense regional fiber network comprises nearly 540,000 fiber strand miles, 5,700 fiber route miles, and over 4,500 on-net locations.  The results of operations of Southern Light are reflected in the Fiber Infrastructure segment beginning July 3, 2017.

Acquisition of Hunt Telecommunications, LLC. On July 3, 2017, we completed the previously announced acquisition of Hunt Telecommunications, LLC (“Hunt”). The Company acquired all of the outstanding equity interests of Hunt for approximately $129 million in cash, including the payoff of existing indebtedness and unpaid transaction expenses, and approximately 1.6 million units in the Operating Partnership with an acquisition date fair value of $41.6 million. Additional contingent consideration of up to $17 million, with an acquisition date fair value of $16.4 million will be paid upon the achievement of certain defined financial revenue milestones. Hunt is a leading provider of data transport to K-12 schools and government agencies with a dense fiber network in Louisiana.  The results of operations of Hunt are reflected in the Fiber Infrastructure segment beginning July 3, 2017.

up-REIT Reorganization.  On May 9, 2017, we completed our reorganization (the “up-REIT Reorganization”) to operate through a customary “up-REIT” structure. Under this structure, the Operating Partnership, which we control as a general partner, holds substantially all of our assets. The financial position and results of operations of the

Operating Partnership do not include the Consumer CLEC Business because Talk America is a direct, wholly-owned subsidiary of Uniti. This structure is intended to facilitate future acquisition opportunities by providing the Company with the ability to use common units of the Operating Partnership (the “OP Units”) as a tax-efficient acquisition currency for future acquisitions of assets or entities. Each OP Unit is exchangeable on a one-for-one basis for shares of our common stock or, at our election, cash of equivalent value.

Issuance of Senior Unsecured Notes. On May 8, 2017, the Company, CSL Capital, LLC and Uniti Fiber Holdings Inc. co-issued $200 million aggregate principal amount of 7.125% Senior Unsecured Notes due December 15, 2024 (the “May 2017 Notes”).  The proceeds from the offering were used to fund a portion of the cash consideration payable in connection with the acquisition of Southern Light. In connection with the up-REIT Reorganization on May 9, 2017, the Operating Partnership replaced the Company as a co-issuer of the May 2017 Notes, and the Company and Uniti Group Finance Inc. became guarantors of the May 2017 Notes. On August 11, 2017, the May 2017 Notes were mandatorily exchanged for notes issued as “additional notes” under the indenture governing our 7.125% Senior Unsecured Notes due December 15, 2024 (the “2024 Notes”).

Issuance of Common Stock. On April 25, 2017, we issued 19.5 million shares of our common stock at a public offering price of $26.50, resulting in proceeds to the Company of $499 million, net of underwriting discounts and commissions, which were used to fund a portion of the cash consideration payable in connection with the acquisitions of Southern Light and Hunt.

Acquisition of NMS. On January 31, 2017, we completed the previously announced acquisition of Network Management Holdings LTD (‘‘NMS’’). At close, NMS owned and operated 366 wireless communications towers in Latin America with an additional 105 build-to-suit tower sites under development. The NMS portfolio spans three Latin America countries with 212 towers in Mexico, 54 in Nicaragua, and 100 in Colombia. The consideration for the 366 wireless towers currently in operation was $62.6 million, which was funded through cash on hand. Under the terms of the purchase agreement, we will acquire the towers under development when construction is completed. As of December 31, 2017, construction was completed on 50 of the 105 towers that were under development at the time of the NMS acquisition, and we acquired the completed towers pursuant to the purchase agreement for approximately $5.1 million.  The results of operations of NMS are reflected in the Towers segment beginning January 31, 2017.

The following table sets forth, for the years ended December 31, 2017 and 2016, revenues and Adjusted EBITDA of our reportable segments:

Revenues

Leasing – Leasing revenues are primarily attributable to rental revenue from leasing our Distribution Systems to Windstream Holdings pursuant to the Master Lease. Under the Master Lease, Windstream Holdings is responsible for the costs related to operating the Distribution Systems, including property taxes, insurance, and maintenance and repair costs. As a result, we do not record an obligation related to the payment of property taxes, as Windstream makes direct payments to the taxing authorities. The Master Lease has an initial term of 15 years with four five-year renewal options and encompasses properties located in 29 states. Rent under the Master Lease is an annual fixed amount of approximately $654 million. Beginning May 2018 and continuing for the remainder of the initial term, rent under the Master Lease is subject to an annual escalation of 0.5%. Rental revenues over the initial term of the Master Lease are recognized in the financial statements on a straight-line basis, representing approximately $670.8 million per year.

The Master Lease provides that tenant funded capital improvements (“TCIs”), defined as maintenance, repair, overbuild, upgrade or replacement to leased network, including without limitation, the replacement of copper

Table of Contents

distribution systems with fiber distribution systems, automatically become property of Uniti upon their construction by Windstream. We receive non-monetary consideration related to TCIs as they automatically become our property, and we recognize the cost basis of TCIs that are capital in nature as real estate investments and deferred revenue. We depreciate the real estate investments over their estimated useful lives and amortize the deferred revenue as additional leasing revenues over the same depreciable life of the TCI assets.

For the year ended December 31, 2017, we recognized $685.1 million of revenue under the Master Lease, which included $14.3 million of TCI revenue. For the year ended December 31, 2016, we recognized $677.4 million of revenue under the Master Lease, which included $6.1 million of TCI revenue. The increase in TCI revenue is attributable to increased investment by Windstream in TCIs. Windstream invested $228 million in TCIs during the year ended December 31, 2017, an increase from $157 million it invested in TCIs during the year ended December 31, 2016. Since the inception of the Master Lease, Windstream has invested a total of $453.5 million in such improvements.

Because a substantial portion of our revenue is derived from lease payments by Windstream pursuant to the Master Lease, there could be a material adverse impact on our consolidated results of operations, liquidity and/or financial condition if Windstream were to default under the Master Lease or otherwise experience operating difficulties and becomes unable to generate sufficient cash to make payments to us. In recent years, Windstream has experienced annual declines in its total revenue and sales.  Most recently, Windstream has endured a challenge from an entity who acquired certain Windstream debt securities for the purpose of seeking an “event of default” under such securities relating to the Spin-Off.  An actual “event of default” would permit the trustee or holders of at least 25% in aggregate principal amount of outstanding of such Windstream debt securities to declare the principal amount of all outstanding Windstream debt to be immediately due and payable. Such an outcome would trigger cross-default provisions in Windstream’s other debt instruments, including Windstream Services’ existing credit facility, which, in turn, would trigger a default under the Master Lease. Accordingly, we monitor the credit quality of Windstream through numerous methods, including by (i) reviewing the credit ratings of Windstream by nationally recognized credit rating agencies, (ii) reviewing the financial statements of Windstream that are publicly available and that are required to be delivered to us pursuant to the Master Lease, (iii) monitoring ongoing litigation and news reports regarding Windstream and its businesses, (iv) conducting research to ascertain industry trends potentially affecting Windstream, and (v) monitoring the timeliness of its lease payments.

In addition to periodic financial statements, Windstream is obligated under the Master Lease to provide us (i) a detailed consolidated budget on an annual basis and any significant revisions approved by Windstream’s board of directors, (ii) prompt notice of any adverse action or investigation by a governmental authority relating to Windstream’s licenses affecting the leased property, and (iii) any information we require to comply with our reporting and filing obligations with the SEC. Furthermore, pursuant to the Master Lease, we may inspect the properties leased to Windstream upon reasonable advance notice, and, no more than twice per year, we may require Windstream to deliver an officer’s certificate certifying, among other things, its material compliance with the covenants under the Master Lease, the amount of rent and additional charges payable thereunder, the dates the same were paid, and any other questions or statements of fact we reasonably request.

Fiber Infrastructure – In our Fiber Infrastructure segment, we recognized $202.8 million of revenue for the year ended December 31, 2017, of which approximately 55.1% was derived from lit backhaul services, approximately 20.6% was derived from internet and voice revenue, approximately 11.3% was derived from construction revenue and approximately 13.0% was derived from other services. For the year ended December 31, 2016, we recognized $70.6 million of revenue Fiber Infrastructure segment, approximately 78% of which was derived from lit backhaul services.  The revenue increase is primarily driven by the timing of the acquisitions of PEG Bandwidth, LLC (“PEG” or “PEG Bandwidth”), Tower Cloud, Southern Light and Hunt.  At December 31, 2017, we had approximately 16,750 customer connections, up from 5,450 customer connections at December 31, 2016. The increase is primarily attributable to the July 3, 2017 acquisitions of Southern Light and Hunt.

Towers – For the year ended December 31, 2017, we recognized $10.1 million of revenue in our Towers segment, of which $7.5 million relates to our Latin American operations, primarily driven by revenues associated with our January 2017 acquisition of NMS.

Table of Contents

At December 31, 2017, the Uniti Towers’ portfolio consisted of 227 wireless communications towers located on 20 states across the Eastern and Central regions in the United States, and 440 wireless communications towers in Latin America.

Consumer CLEC – For the year ended December 31, 2017, we recognized $18.1 million of revenue from the Consumer CLEC Business, compared to $22.5 million for the period for the year ended December 31, 2016. The decrease is primarily attributable to a loss of customers during the period. We served approximately 28,500 customers as of December 31, 2017, a 23% decrease from 37,000 at December 31, 2016. The decrease in customers is due to the effects of competition and customer attrition.

Interest Expense

Interest expense for the year ended December 31, 2017, totaled $306.0 million, which includes non-cash interest expense of $23.1 million resulting from the amortization of our debt discounts and debt issuance costs. Interest expense for the year ended December 31, 2016, totaled $275.4 million, which includes non-cash interest expense of $16.0 million resulting from the amortization of our debt discounts and debt issuance costs. The increase is primarily related to interest expense on the additional $150 million aggregate principal amount of 6.00% Senior Secured Notes issued on June 16, 2016 as an add-on to the Company’s existing senior secured notes (the “add-on Secured Notes”) and the 2024 Notes of $41 million. This increase was partially offset by approximately $19 million of interest savings related to the repricing of $2.1 billion of term loans outstanding under our senior secured credit agreement. Effective February 9, 2017, interest on the term loans was LIBOR plus 3.00% per annum (with a minimum LIBOR rate of 1.0%), compared to LIBOR plus 4.0% per annum (with a minimum LIBOR rate of 1.0%) for the year ended December 31, 2016.

Depreciation and Amortization Expense

We incur depreciation and amortization expense related to our property, plant and equipment, corporate assets and intangible assets. Charges for depreciation and amortization for the year ended December 31, 2017 totaled $434.2 million (47.4% of revenue), which included property, plant and equipment depreciation of $415.9 million and intangible asset amortization of $18.3 million. Charges for depreciation and amortization for the year ended December 31, 2016 totaled $376.0 million (48.8% of revenue), which included property, plant and equipment depreciation of $369.9 million and intangible asset amortization of $6.1 million. The increase is primarily driven by the timing of the acquisitions of PEG, Tower Cloud, Southern Light and Hunt.

General and Administrative Expense

General and administrative expenses include compensation costs (including stock-based compensation awards), professional and legal services, corporate office costs and other costs associated with the administrative activities of our segments. For the year ended December 31, 2017, general and administrative costs totaled $72.0 million (7.9% of revenue), which includes $7.7 million of stock-based compensation expense. For the year ended December 31, 2016, general and administrative costs totaled $35.4 million (4.6% of revenue), which includes $4.8 million of stock-based compensation expense. The increase is primarily driven by the timing of the acquisitions of PEG and Tower Cloud, which closed on May 2, 2016 and August 31, 2016, respectively, as well as the acquisition of Southern Light and Hunt that closed on July 3, 2017.

Operating Expense

Operating expense for the year ended December 31, 2017, totaled $102.2 million (11.2% of revenue), and consisted of $83.5 million (9.1% of revenue) of expense related to the operation of the Fiber Infrastructure operations, $5.1 million (0.6% of revenue) of expense related to the Tower operations and $13.5 million (1.5% of revenue) of expense related to the Consumer CLEC Business. For the year ended December 31, 2016, operating expenses totaled $49.7 million (6.4% of revenue), which related to the operation of the Consumer CLEC Business ($17.4 million) and Fiber Infrastructure operations ($32.1 million).

33

Table of Contents

The increase to Fiber Infrastructure operating expense is primarily driven by the timing of the acquisitions of PEG and Tower Cloud, which closed on May 2, 2016 and August 31, 2016, respectively, as well as the acquisition of Southern Light and Hunt that closed on July 3, 2017.  For the year ended December 31, 2017, Fiber Infrastructure operating expenses included $21.1 million of construction-related expenses, $15.9 million of lit service expense, $11.0 million of tower rent, $10.4 million of maintenance expense, $7.0 million of dark fiber rent and $4.8 million of payroll-related expense. For the year ended December 31, 2016, Fiber Infrastructure operating expenses included $7.0 million of tower rent, $5.3 million of payroll-related expense and $4.3 million of lit service expense.

The increase to Tower operating expense is primarily driven by the timing of the acquisition of NMS, which closed on January 31, 2017.  For the year ended December 31, 2017, Tower operating expenses included $3.2 million of tower rent, $0.9 million of site monitoring expenses and $0.2 million of insurance expense.

Expense associated with the Consumer CLEC Business is primarily attributable to the Wholesale Agreement and the Master Services Agreement entered between us and Windstream in connection with the Spin-Off, and also included costs arising under the interconnection agreements with other telecommunication carriers. Expense associated with the Wholesale Agreement and Master Services Agreement for the year ended December 31, 2017 totaled $10.2 million (1.1% of revenue) and $1.3 million (0.1% of revenue), respectively, and expense associated with the Wholesale Agreement and the Master Services Agreement for the year ended December 31, 2016 totaled $12.5 million (1.6% of revenue) and $1.7 million (0.2% of revenue), respectively.

Other Expense

Other expense for the year ended December 31, 2017, totaled $11.3 million (1.2% of revenue), primarily as a result of a net unrealized loss of $10.7 million for mark-to-market adjustments on our contingent consideration arrangements.

Income Tax (Benefit) Expense

We recorded a $38.8 million benefit in income tax benefit for the year ended December 31, 2017. This benefit was primarily driven by the release of valuation allowance and impact of corporate tax reform. Income tax benefit of $8.2 million was recorded for the release of a valuation allowance related to the acquisitions of Southern Light and Hunt. The Southern Light and Hunt transactions resulted in the recording of a deferred tax liability, and this future reversal of taxable temporary differences supports the realization of deferred tax assets which previously had a valuation allowance. $17.0 million relates to revision of ending net deferred tax asset balances to the lower future corporate tax rate.

Comparison of the year ended December 31, 2016 to the period from April 24, 2015 to December 31, 2015

Because we were formed in connection with the Spin-Off from Windstream Holdings on April 24, 2015, the comparable period results discussed in this section cover only the 252-day period from April 24, 2015 to December 31, 2015. As such, there are inherent limitations to period over period comparability. This discussion should be read in conjunction with the accompanying audited financial statements, and the notes thereto set forth in Part II, Item 8 of this Annual Report on Form 10-K.
