"Spok continues to execute at a high level and we remain confident in our full year financial projections,” said Vincent D. Kelly, chief executive officer of Spok Holdings, Inc. “Our focus is to generate cash flow and return capital to stockholders, while responsibly investing for future growth. On a year-to-date basis, we have done and will continue to do so. We also continue to make progress in key performance areas, including net income and cash generation, wireless ARPU trends, software revenue growth and backlog levels. We were able to accomplish this while continuing to invest in our Spok Care Connect and Wireless solutions. Through the first nine months of the year, we have invested more than $9 million in our world-class product platform and believe that these investments will create shareholder value into the future.

"Spok continues its proud legacy of balancing the necessary investments in our products and infrastructure with returning capital to our stockholders," continued Kelly. "In the third quarter, we generated more than $6.6 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 balances continued to grow in the third quarter, totaling nearly $21.4 million at September 30, 2025. All else remaining equal, we expect cash balances to continue to grow through the remainder of the year.

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 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.

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 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.
