| 2 This presentation includes forward-looking statements that are subject to risks and uncertainties that could cause actual future events and results to differ materially from those expressed in the forward-looking statements. Forward-looking statements are typically identified by words or phrases such as “will,” “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” “target,” “forecast” and other words and terms of similar meaning. Forward-looking statements include, but are not limited to, guidance regarding 2025 financial and operational results and our ability to execute our 2025 strategic goals supporting the guidance, including the planned acceleration of our fiber deployment and our ability to increase our fiber penetration; the number of households or locations that we may be able to serve generally and related to funding from various current or future state and federal broadband programs, public-private partnerships with government entities, the Rural Digital Opportunity Fund, and the BEAD program; opportunities related to strategic sales, products, and strategic revenue growth across our business units; expectations regarding expense management activities, and the timing and benefit of such activities; statements regarding possible benefits and opportunities related to the proposed transaction with Until Group, Inc., announced publicly in May 2024; and any other statements regarding plans, objectives, expectations and intentions and other statements that are not historical facts. These statements, along with other forward-looking statements regarding Windstream’s overall business outlook, are based on estimates, projections, beliefs, and assumptions that Windstream believes are reasonable but are not guarantees of future events, performance, or results. Actual future events and results may differ materially from those expressed in these forward-looking statements as the result of a number of important factors. Important factors that could cause actual results to differ materially from those indicated by such forward-looking statements include risks and uncertainties relating to increased competitive pressures as state and federal broadband funding programs provide opportunities for new entrants in our markets, or prefer municipal cooperatives, leading to possible overbuilding of our network; our ability to, and the extent to which, we participate in broadband funding programs, such as BEAD, and are able to successfully secure funding via competitive bidding processes over competitors; the uncertainty surrounding the BEAD program in light of increased focus on the program by members of the federal legislative and executive branches, including changes to the program, timing of implementation of the program or in what form the program continues; the effect of any changes in federal or state governmental regulations or statutes or new requirements or restrictions contained in executive orders that could impact our business or the business of our customers; uncertainty created in the federal Universal Service Fund program based on the pending legal case at the U.S. Supreme Court, including possible impact on future funding under the Rural Digital Opportunity Fund; increased oversight or enforcement activities by state or federal agencies, particularly based on our status as a federal and state government contractor; that the proposed transaction with Uniti Group, Inc., could cause distraction by management and an allocation of resources that otherwise would have been attributed to the business; risks and uncertainties from cost pressures, tariffs, trade disputes, or inflation on our business or on our customers’ communications and payment decisions and on the business of our vendors; adverse economic, political or market conditions related to foreign wars or unrest, political upheaval epidemics, pandemics, or disease outbreaks, and the impact of these conditions on our business operations and financial position and on our customers; any supply chain impact from tariffs or trade disputes on our vendors that may impact our business operations and our customers’ ability to operate their business; that the expected benefits of cost and expense management activities are not realized or adversely affect our sales and operations or are otherwise disruptive to our business and personnel; the impact of new, emerging, or competing technologies and our ability to utilize these technologies to provide services to our customers; and general U.S. and worldwide economic conditions and related uncertainties. Windstream does not undertake any obligation to publicly update any forward-looking statement, whether as a result of new information, future events or otherwise.
