Summary
Spok Holdings closed fiscal 2024 with fourth-quarter revenue of $33.9 million, essentially flat from the prior-year quarter. Operating income rose 13.6% to $4.6 million, and net income increased 8.3% to $3.6 million. Operating margin was 13.7%, up from the prior-year quarter. The quarter's operating cash flow was $8.4 million, down 28.7% from a year earlier.
For the full year, revenue fell 1.0% to $137.7 million. Full-year operating income was $19.0 million, down 10.7%, and net income was $15.0 million, down 4.5%. Diluted earnings per share for the full year were $0.73, down 5.2%. Full-year operating margin was 13.8%, down from the prior year. Full-year operating cash flow was $28.9 million, up 10.5%, while capital expenditures were $3.2 million, down 6.1%. Deferred revenue at December 31, 2024 was $28.9 million, up 7.4% from a year earlier. Fourth-quarter adjusted operating expenses were $28.3 million, down 1.6%, and full-year adjusted operating expenses were $113.4 million, up 0.6%.
Software operations bookings totaled $7.1 million in the fourth quarter, up 73.2% from the fourth quarter of 2023, and full-year bookings were $34.1 million, up 13.2%. The company signed 20 six- and seven-figure contracts in the quarter and 82 for the year, which exceeded prior-year levels by more than 22%. 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% year over year. Management said it strengthened its sales, product, and development teams while making progress on its product roadmap. Software backlog ended 2024 at $62.4 million, up 21.7% from a year earlier. That backlog excludes $5.6 million and $4.9 million of contractual obligations deemed cancellable by the customer without significant penalty as of December 31, 2024 and 2023, respectively.
Wireless trends remained challenging. Units in service fell to 720,000 at December 31, 2024 from 765,000 a year earlier, a decline of 5.9%. Active transmitters fell 5.2% to 3,048. Spok returned $6.3 million to stockholders in the fourth quarter and $26.4 million for the full year. The board declared a regular quarterly dividend of $0.3125 per share, payable March 31, 2025.
Management provided full-year 2025 guidance. The company expects total revenue of $134.0 million to $142.0 million. Adjusted EBITDA is guided to $27.5 million to $32.5 million. At the midpoint, Spok expects consolidated revenue growth in 2025, led by continued software growth that is partially offset by slight declines in wireless revenue. The midpoint of adjusted EBITDA guidance is expected to be consistent with 2024, with additional growth potential at the high end of the range. Adjusted EBITDA was $7.1 million in the fourth quarter, up 8.4%, and $29.2 million for the full year, down 3.9%. The company said adjusted EBITDA of $29.2 million more than covered the $26.4 million returned to stockholders.
Risks remain. Spok's wireless business faces a secular decline in paging units, and management expects demand for wireless services to keep falling as customers shift to broadband technologies. The company's ability to rationalize its wireless network to lower costs without disrupting service is a named risk. Software revenue can be lumpy because of long sales cycles, fixed-bid contracts, and project complexity that may affect the timing of revenue recognition. Spok's primary market is healthcare, particularly hospitals, and it has expanded its focus to smaller hospitals with shorter sales cycles. Spok depends on the healthcare industry, competes with larger firms that have greater resources, and relies on third-party vendors, data centers, and IT systems. Cybersecurity and data breaches, product defects, regulatory changes, and the retention of key personnel are also cited risks. The company's dividend and share repurchase program depend on cash generation and could be reduced if operating cash flow and cash on hand are not sufficient.

Risks
Spok expects wireless subscriber results, units in service and revenue to continue to decline for the foreseeable future; MD&A reports units in service fell from approximately 765 thousand at December 31, 2023 to approximately 720 thousand at December 31, 2024. Maintaining positive wireless operating cash flow depends on timely expense reductions as vendor negotiating leverage diminishes.
The active network rationalization program consolidates wireless networks and transmitter locations to match a smaller subscriber base; active transmitters declined 5.2% from December 31, 2023 to December 31, 2024. Service disruptions from rationalization could increase gross subscriber cancellations and wireless revenue erosion, and FCC minimum frequency commitments may limit further consolidation.
More than 75% of revenue comes from sales to United States hospitals and other healthcare provider organizations, exposing Spok to healthcare reform, reimbursement policies, and macroeconomic pressures that can lengthen sales cycles and reduce customer spending. MD&A notes the primary market remains healthcare with a focus on prominent hospitals.
The FCC in early 2025 proposed expanding adjacent 900 MHz broadband use and eliminating 500 KHz guard bands between those frequencies and Spok's paging spectrum, which could cause harmful interference and make paging services less effective and affected spectrum licenses less valuable. FDA regulation of certain software products and potential universal service fee changes add compliance and cost risks.
A substantial portion of revenue comes from healthcare customers, and many customers use Spok wireless devices that do not encrypt text messages; despite disclaimers, Spok could be held responsible for HIPAA or other privacy violations. Evolving GDPR, CCPA and similar laws increase compliance costs and enforcement risk.
Software revenue growth depends on a sales cycle that may take six to 18 months from initial contact to final sales order, and healthcare customer budget constraints and multiple approvals can cause bookings and revenue to fluctuate month to month, quarter to quarter and year to year.
Execution of the growth plan requires retaining highly skilled software engineers and sales personnel, and competition for talent remains intense with upward compensation pressure from inflation. If equity awards decline in perceived value, Spok may have greater difficulty hiring and retaining employees than competitors with greater name recognition and financial resources.
Spok maintained a $2.3 million valuation allowance at December 31, 2024 and 2023 against federal foreign tax credits and certain state net operating losses; if future taxable income is insufficient to use deferred tax assets, financial condition and results could be materially affected.
The company uses cash on hand and operating cash flow to pay quarterly dividends of $0.3125 per share; MD&A states that if operating cash flow and cash on hand are insufficient, it may need to reduce or eliminate cash dividends.
Spok purchases paging equipment from third-party vendors, and reduced industry demand has caused some suppliers to cease manufacturing paging devices or increase prices. A lack of paging equipment could impair Spok's ability to provide certain wireless messaging services and lead to additional wireless revenue erosion.
Spok faces intense competition for wireless subscribers from other paging providers and alternate wireless communications providers such as mobile phone and mobile data service providers, which could pressure prices, reduce margins and cause loss of market share. Competitors may innovate or partner faster in clinical communication solutions.
Recessionary cycles, higher interest rates, inflation, unemployment, and tax law changes could increase wireless subscriber cancellations, accelerate revenue erosion, and delay or reduce software bookings and revenue. Healthcare customers are sensitive to regulatory and reimbursement uncertainty, which can lengthen sales cycles and limit price increases.
