(NASDAQ: SPOK), a global leader in healthcare communications, today announced results for the fourth quarter and full year ended December 31, 2024.

"I am proud of the very strong finish to 2024 that our team was able to deliver in the fourth quarter and their continued dedication to Spok's mission to grow software revenue, generate cash flow and

return capital to stockholders,” said Vincent D. Kelly, chief executive officer of Spok Holdings, Inc. “In 2024 we achieved numerous operational and financial milestones as a year-over-year increase in software revenue was coupled with essentially flat year-over-year operating expenses, despite continued growth in our investment in Spok's products and services. In addition, we strengthened our sales, product and development teams while making tremendous progress 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 22% from 2023. Software operations bookings for the year totaled $34.1 million and were up more than 13% from an already strong level of bookings in 2023. Included in this performance were 82 six- and seven-figure customer contracts, which exceeded prior year levels by more than 22%. Additionally, software operations bookings included 40 multi-year engagements, up significantly from the prior year, and the fourth quarter average new contract size increased by more than 50% on a year-over-year basis. Lastly, we were able to generate this growth, while increasing customer satisfaction scores and retention.

"I believe Spok has done an excellent job of balancing the necessary investments required for 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 2024, we generated $15.0 million of net income and $29.2 million of adjusted EBITDA, which more than covered the $26.4 million we returned to our stockholders. However, at the same time, we invested more than $11.5 million in our products and services through our R&D efforts. We remain committed to this approach of balancing cash returned to our stockholders with investments in our product offering and believe our extensive experience operating our established and well-regarded communication solutions will create significant value going forward. In short, we believe it is important to make money and regularly return capital to our stockholders as we move forward.

"Based on our performance in 2024, and the numerous financial and operational milestones we achieved during the year, we are providing 2025 guidance estimates for revenue and adjusted EBITDA. This guidance reflects the team's confidence in being able to outpace our last year's performance. At the midpoint of the guidance range, we believe we are on track to again grow consolidated revenue in 2025, on a year-over-year basis, with continued growth in software revenue, partially offset with slight declines in wireless 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) 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.

(2) Software backlog excludes $5.6 million and $4.9 million of contractual obligations that are deemed cancellable by the customer without significant penalty as of December 31, 2024 and 2023, respectively.

Regarding financial guidance, the Company expects the following for the full year 2025:

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 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.
