"I am so proud of the very strong performance our team was able to deliver in 2023, and their continued dedication to Spok's mission to grow revenue, generate cash flow and return capital to stockholders,” said Vincent D. Kelly, chief executive officer of Spok Holdings, Inc. “Last year we achieved numerous operational and financial milestones as a 3.3% year-over-year increase in total revenue, the first in the Company's history, was coupled with a more than 12% decline in operating expenses. In addition, we strengthened our sales team and made tremendous progress in executing our product roadmap and building a robust product pipeline, both in terms of size and quality. We exited last year with record Software backlog levels, which were up nearly 28% from 2022. Software operations bookings for the year totaled $30.1 million and were up 22% from an already strong level of bookings in 2022. Included in this performance were 67 six-figure customer contracts, which exceeded prior year levels. Software operations bookings included the largest customer contract ever signed in the Company's history and we saw a doubling of our average new contract size. Most importantly, last year's performance included 30 multi-year engagements, up approximately 60% from the level generated in 2022. Lastly, we were able to generate this growth, while increasing customer satisfaction scores and retention.

"In short, I believe Spok has done an excellent job of balancing the necessary investments we needed to make in our products and infrastructure in order to fuel future growth, while continuing to create stockholder value and return capital to our stockholders," continued Kelly. "In 2023, we generated nearly $16 million of net income and more than $30 million of adjusted EBITDA, which more than covered the $25.6 million we returned to our stockholders. However, at the same time, we invested more than $10.5 million in our products and services. We remain committed to this approach and believe our extensive experience operating our established and well-regarded communication solutions will create significant value going forward.

"Based on our performance in 2023, and the numerous financial and operational milestones we achieved during the year, we are providing guidance estimates for revenue and adjusted EBITDA generation for this year. This guidance reflects the team's confidence in being able to outpace our 2023 performance. At the midpoint of the guidance range, we believe we are on track to again grow consolidated revenue in 2024, on a year-over-year basis, with slight declines in wireless revenue being more than offset by continued growth in software revenue. We also anticipate that the midpoint of our adjusted EBITDA guidance will be consistent with last year, with additional growth potential at the high-end of the guidance range. Of course, we will continue to update you on our outlook each quarter when we report our results," concluded Kelly.

Financial Highlights:

(1) For the three months and year ended December 31, 2022 Net income includes a non-cash benefit of $21.9 million related to the release of a previously established valuation allowance in alignment with our projections of future taxable income.

(1) Software operations bookings includes net new (i.e., new customers or incremental add-on sales to existing customers) sales of license, professional services, equipment, and first-year maintenance.

This press release contains the following non-GAAP financial measures: adjusted operating expenses and adjusted EBITDA. Adjusted operating expenses excludes depreciation, amortization 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, amortization and accretion expense, stock-based compensation expense, impairment of intangible assets and severance and restructuring. With respect to our expectations under "Financial Guidance" 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; economic conditions such as recessionary economic cycles, 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 U.S. healthcare industry; the sales cycle of our software solutions and services can run from six to eighteen months, making it difficult to plan for and meet our sales objectives and bookings on a steady basis quarter-to-quarter and year-to-year; 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; the reliability of our networks and servers and our ability to prevent cyber-attacks and other security issues and disruptions; our reliance on data centers and other systems and technologies provided by third parties, and technology systems and electronic networks supplied and managed by third parties; cyberattacks, data breaches or other compromises to our or our critical third parties' 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.
