Summary
Spok Holdings reported flat fourth quarter revenue and lower quarterly profit. Total revenue was $33.86 million, flat versus the prior-year quarter. Full year revenue rose 1.5% to $139.71 million. Operating income fell 15.0% to $3.94 million in the quarter. Net income fell 19.6% to $2.93 million. Operating margin was 11.6%, down 2.0 percentage points. The quarter showed a split between the top and bottom lines. Revenue held steady, but lower operating income weighed on profit. Full year results were better. Operating income rose 3.9% to $19.71 million. Net income rose 6.1% to $15.88 million. Diluted EPS was $0.75, up 2.7%. Full year operating margin was 14.1%, up 0.3 percentage points.
Cash flow improved in the quarter. Operating cash flow rose 37.1% to $11.52 million in Q4. Full year operating cash flow was flat at $28.95 million. Capital expenditures rose 63.2% to $1.40 million in Q4 and 17.0% to $3.75 million for the full year. The company kept investing in property and equipment. Deferred revenue rose 7.4% to $31.08 million. Remaining performance obligations, reported as software backlog, fell 6.7% to $58.20 million. The press release notes backlog excludes $16.1 million and $5.6 million of contractual obligations deemed cancellable by customers at December 31, 2025 and 2024, respectively.
Operational metrics were mixed. Q4 software operations bookings rose 14% year over year and nearly 83% sequentially. The quarter included 12 six-figure and 2 seven-figure customer contracts. Full year bookings fell 4.5% to $32.6 million. Wireless ARPU was $8.26 in Q4, up 1.2% year over year. Full year ARPU was $8.20, up 2.9%. Wireless units in service ended the year at 675 thousand, down from 720 thousand. Quarterly net churn improved to 1.3%, a 12-basis point improvement from the prior quarter. Active transmitters fell 5.9% to 2,869 and FTEs rose 2.7% to 421. Adjusted EBITDA fell 5.0% to $6.7 million in Q4, and full year adjusted EBITDA was $29.0 million. Bookings strength in the quarter contrasts with the full year decline, and the wireless base kept shrinking.
The board declared a regular quarterly dividend of $0.3125 per share, payable March 31, 2026. Capital returned to stockholders was $6.4 million in Q4 and $27.3 million for the full year. Management provided full year 2026 guidance for total revenue and adjusted EBITDA of $27.5 million to $32.5 million. The CEO said the high end of the guidance range would mean consolidated revenue growth in 2026, led by software revenue and partly offset by wireless declines. The midpoint of adjusted EBITDA guidance is up from 2025. Guidance covers the full fiscal year.
Risks stay concentrated in wireless. The company depends on the healthcare industry and faces a long sales cycle for software. Competition comes from larger firms and new technologies. Named risks include wireless network rationalization, retaining key personnel, sales productivity, acquisition integration, recession, trade disputes, tariffs, higher interest rates, inflation, unemployment, cyberattacks and data breaches, data privacy laws, and reliance on third-party vendors and IT systems. Spok also cites undetected defects, bugs or security vulnerabilities in its products. The company ended 2025 with no debt and plans to use cash for working capital, investments, dividends and share repurchases. The wireless decline remains a structural headwind.

Risks
Spok expects wireless subscriber results, units in service and revenue will continue to decline for the foreseeable future; paging revenue decreased 3.4% for the year ended December 31, 2025 compared to 2024, and active transmitters declined 5.9% from December 31, 2024 to December 31, 2025. Maintaining positive wireless operating cash flow depends on substantial and timely reductions in wireless operating expenses, but negotiating leverage with vendors diminishes as service and product volumes fall.
The company's network rationalization program consolidates wireless networks and transmitter locations to match a smaller subscriber base; active transmitters declined 5.9% from December 31, 2024 to December 31, 2025, and implementation could adversely impact service, increase gross subscriber cancellations or accelerate wireless revenue erosion.
Spok generates more than 75% of revenue from U.S. hospitals and other healthcare provider organizations, making results sensitive to healthcare regulation, reimbursement policy, macroeconomic conditions and customer budget constraints. These factors can lengthen the sales cycle and limit the company's ability to increase prices.
Software revenue growth depends on a long sales cycle of six to 18 months, and new sales hires may take nine to 12 months to reach full productivity. Bookings and revenue can fluctuate because of customer budget constraints, multiple approvals and administrative issues in the healthcare market; remaining performance obligations were $58.20 million at FY2025 Q4, down 6.7% compared with FY2024 Q4.
Execution of the software growth plan requires retaining and hiring highly skilled software engineers and sales personnel; competition for talent is intense, compensation faces upward pressure, and stock price volatility or lower equity award value could impair recruiting and retention.
In early 2025, the FCC proposed to expand adjacent 900 MHz spectrum use for broadband by eliminating 500 KHz guard bands, which could cause harmful interference, make paging services less effective and reduce the value of affected spectrum licenses. The FCC has also considered a numbers-based universal service fee methodology that could increase costs and reduce demand if passed through to customers.
Certain software products are regulated by the FDA as medical devices, requiring registration, labeling, medical device reporting, removal and correction, and good manufacturing practice compliance; delays in FDA clearance or changes to FDA regulations could restrict marketing or sales.
More than 75% of revenue comes from healthcare customers, and many use Spok wireless devices that do not encrypt text messages; increasing HIPAA/HITECH compliance concerns are causing healthcare organizations to re-evaluate paging subscriptions for clinical use cases when users lack encrypted pagers, and GDPR/CCPA obligations add compliance risk.
Spok and its service providers regularly experience cyberattacks, including DDoS, phishing/BEC, supply chain attacks and malware; attackers increasingly use artificial intelligence to evade detection, and any material incident could cause data loss, regulatory action, litigation and reputational harm.
The company had a valuation allowance of $1.9 million at December 31, 2025 and $2.3 million at December 31, 2024 against deferred income tax assets, and realization of net operating loss carryforwards depends on generating sufficient taxable income as software revenue grows and wireless subscribers and revenue decline.
Spok continues to evaluate acquisitions that may require cash, debt or equity issuance; integration challenges, unforeseen liabilities, dilution and failure to achieve expected synergies could adversely affect financial condition and cash flows.
The company depends on third-party vendors for paging equipment, and reduced industry demand has caused some suppliers to cease manufacturing or increase prices; a lack of paging equipment could impair wireless messaging services and lead to additional wireless revenue erosion.
Recessionary cycles, trade disputes, tariffs, higher interest rates, inflation and tax law changes could reduce demand for Spok's services and delay or reduce software revenue and bookings, with particular sensitivity in the healthcare customer base.
Spok evaluates goodwill for impairment at least annually in the fourth quarter; a decline in the fair value of the reporting unit could require significant impairment charges. No goodwill impairment was recorded for 2025, 2024 or 2023.
