NEWS RELEASE

"I am very proud of our Spok team as they were able to regain the positive momentum that we saw in the beginning of 2025,” said Vincent D. Kelly, chief executive officer of Spok Holdings, Inc. “In the fourth quarter, we generated a nearly 83% sequential increase in software operations bookings, while continued growth in average revenue per wireless unit drove a slight increase in wireless revenue. Our focus continues to be to generate cash flow and return capital to stockholders, while responsibly investing for future growth. In 2025, we demonstrated our ability to do this and have positioned ourselves to continue this tradition in 2026. In addition to returning $27.3 million to our stockholders in 2025, we continued to invest in our Spok Care Connect and Wireless solutions with over $12 million devoted to developing our world-class product platform. We believe that these investments will continue to create stockholder value.

"Spok continues its proud legacy of balancing the necessary investments in our products and infrastructure with returning capital to our stockholders," continued Kelly. "In 2025, we generated $29 million of adjusted EBITDA and returned the majority of that amount to our stockholders in the form of our regular quarterly dividend. After hitting its low point in the first quarter due to seasonal working capital needs, our cash, and cash equivalents balances continued to grow throughout the year, totaling nearly $25.3 million at year-end, up approximately $4 million from the prior quarter.

"Based on our positive momentum in the fourth quarter of 2025, and our visibility into our very robust product sales pipeline, we provided full year 2026 financial guidance estimates for revenue and adjusted EBITDA. At the high-end of the guidance range, we are on track to again grow consolidated revenue in 2026, on a year-over-year basis, with continued growth in software revenue, partially offset with declines in wireless revenue. The midpoint of our adjusted EBITDA guidance is also up from 2025." concluded Kelly.

Non-GAAP Financial Measures
This press release contains the following non-GAAP financial measures: adjusted operating expenses and adjusted EBITDA. Adjusted operating expenses excludes depreciation and accretion expense, impairment of intangible assets and severance and restructuring costs. Adjusted EBITDA represents net income/(loss) before interest income/expense, income tax benefit/expense, depreciation and accretion expense, stock-based compensation expense, impairment of intangible assets, legal costs unrelated to core business activities and non-recurring in nature, and severance and restructuring. With respect to our expectations under "Financial Outlook" above, reconciliation of adjusted EBITDA to net income is not available without unreasonable efforts on a forward-looking basis due to the high variability, complexity and uncertainty with respect to certain items included in net income that are excluded from adjusted EBITDA, in particular, income tax benefit/expense, stock-based compensation expenses, impairment of intangible assets, severance and restructuring and other non-recurring expenses. These items can have unpredictable fluctuations based on unforeseen activity that is out of our control and/or cannot be reasonably predicted.
We believe that these non-GAAP financial measures provide useful information to management and investors regarding certain financial and business trends relating to Spok's financial condition and results of operations. We use these non-GAAP measures for financial, operational, and budgetary decision-making purposes, to understand and evaluate our core operating performance and trends, and to generate future operating plans. We believe that these non-GAAP financial measures permit

us to more thoroughly analyze key financial metrics used to make operational decisions and allow us to assess our core operating results. We believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing our financial measures with other software companies who present similar non-GAAP financial measures. We adjust for certain items because we do not regard these costs as reflective of normal costs related to the ongoing operation of the business in the ordinary course. In general, these items possess one or more of the following characteristics: non-cash expenses, factors outside of our control, items that are non-operational in nature, and unusual items not expected to occur in the normal course of business. We believe it is important to exclude these costs, given that they do not represent future operational costs under this strategic business plan. This allows us to assess the underlying performance of our core business under this new strategic business plan.
We do not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principle of these non-GAAP financial measures is that they exclude significant amounts that are required by GAAP to be recorded in the Company's financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgment by management about which items are excluded or included in determining these non-GAAP financial measures. In order to compensate for these limitations, management presents non-GAAP financial measures in connection with GAAP results. We urge investors to review the reconciliation of our non-GAAP financial measures to the comparable GAAP financial measures, which are included in this press release, and not to rely on any single financial measure to evaluate our business.
Safe Harbor Statement under the Private Securities Litigation Reform Act
Statements contained herein or in prior press releases which are not historical fact, such as statements regarding our future operating and financial performance, are forward-looking statements for purposes of the safe harbor provisions under the Private Securities Litigation Reform Act of 1995. These forward-looking statements involve risks and uncertainties that may cause our actual results to be materially different from the future results expressed or implied by such forward-looking statements. Factors that could cause actual results to differ materially from those expectations include, but are not limited to, our ability to manage wireless network rationalization to lower our costs without causing disruption of service to our customers; our ability to retain key management personnel and to attract and retain talent within the organization; the productivity of our sales organization and our ability to deliver effective customer support; our ability to identify potential acquisitions, finance, consummate and successfully integrate such acquisitions, and achieve the expected benefits of such acquisitions; economic conditions, such as recessionary economic cycles, the impact of trade disputes, tariffs and other trade protection measures, higher interest rates, inflation and higher levels of unemployment; risks related to our overall business strategy, including maximizing revenue and cash generation from our established businesses and returning capital to stockholders through dividends and repurchases of shares of our common stock; competition for our services and products from new technologies or those offered and/or developed from firms that are substantially larger and have much greater financial and human capital resources; continuing decline in the number of paging units we have in service with customers, commensurate with a continuing

decline in our wireless revenue; our ability to address changing market conditions with new or revised software solutions; undetected defects, bugs, or security vulnerabilities in our products; our dependence on the United States healthcare industry; long sales cycle of our software solutions and services; our reliance on third-party vendors to supply us with wireless paging equipment; our ability to maintain successful relationships with our channel partners; our ability to protect our rights in intellectual property that we own and develop and the potential for material litigation claiming intellectual property infringement by us; our use of open source software, third-party software and other intellectual property; our reliance on data centers and other computer systems, hardware, software and satellite networks and telecommunications systems infrastructure (collectively, "IT Systems") and technologies provided by third parties, and technology systems and electronic networks supplied and managed by third parties; cyberattacks, data breaches, system disruptions or other compromises to our or our critical third parties’ IT Systems, data, products or services; our ability to realize the benefits associated with our deferred income tax assets; future impairments of our long-lived assets or goodwill; risks related to data privacy and protection-related laws and regulation; and our ability to manage changes related to regulation, including laws and regulations affecting hospitals and the healthcare industry generally, as well as other risks described from time to time in our periodic reports and other filings with the Securities and Exchange Commission. Although Spok believes the expectations reflected in the forward-looking statements are based on reasonable assumptions, it can give no assurance that its expectations will be attained. Spok disclaims any intent or obligation to update any forward-looking statements.
