Spok Holdings, Inc. (NASDAQ:SPOK), a global leader in healthcare communications, today announced results for the first quarter ended March 31, 2021. In addition, the Company's Board of Directors declared a regular quarterly dividend of $0.125 per share, payable on June 24, 2021, to stockholders of record on May 25, 2021.

Key First Quarter 2021 Operating Highlights:

First quarter 2021 software revenue of $15.9 million included $9.4 million of maintenance revenue and $6.5 million of operations revenue. This was consistent with first quarter 2020 software revenue of $15.9 million, which included $9.7 million of maintenance revenue and $6.2 million of operations revenue.
Software bookings in the first quarter of 2021 totaled $14.6 million, compared to $15.6 million in the prior year quarter. First quarter software bookings included Spok Go® deals with an aggregate total contract value of approximately $0.7 million. First quarter software bookings also included $5.9 million of legacy operations bookings and $8.0 million of maintenance renewals. As of March 31, 2021, the software revenue backlog totaled $48.8 million, compared to the backlog of $49.1 million at March 31, 2020.
The quarterly rate of paging unit erosion was 1.2% in the first quarter of 2021, compared to paging unit erosion of 1.3% in the first quarter of 2020. Gross disconnects were down on a year-over-year basis.
Total paging ARPU (average revenue per unit) in the first quarter of 2021 totaled $7.34, up from ARPU of $7.31 in the first quarter of 2020, primarily due to the recovery of Telecommunications Service Charges (TRS) that began in early 2021, and general increases of Universal Service Fees (USF). USF and TRS fees are effectively pass-through items that have corresponding costs associated with them. Excluding these pass-through items, ARPU would have declined in-line with historical trends.
Operating expenses in the first quarter of 2021 totaled $37.8 million, down from $41.4 million in the first quarter of 2020. Adjusted operating expenses (which excludes depreciation, amortization and accretion charges, and includes capitalized software development costs) totaled $38.0 million in the first quarter of 2021, down more than 7% from adjusted operating expenses of $40.9 million in the first quarter of 2020.
Capital expenses were $0.7 million in the first quarter of 2021, compared to $1.0 million in the first quarter of 2020.
The number of full-time equivalent employees as of March 31, 2021 totaled 603, compared to 620 at March 31, 2020.
Capital paid to stockholders in the first quarter of 2021 aggregated $2.7 million. This came in the form of the Company's regular quarterly dividend.
The Company's cash, cash equivalents and short-term investments balance as of March 31, 2021, was $71.6 million, compared to $78.7 million at December 31, 2020.

Management Commentary:

"We are encouraged by our performance in the first quarter and believe it sets a solid foundation for the remainder of 2021, as we continue our transition from a traditional communications company to an integrated clinical software-based business," said Vincent D. Kelly, president and chief executive officer. "While we are still operating in a very challenging environment, we are making tangible progress executing against our strategy, and we are beginning to see benefits to our business as a result of the increasing prevalence of COVID-19 vaccines. Notably, our sales and services teams are resuming more normalized travel schedules and visiting customer sites in-person that they had been prevented from visiting since early last year.

"We launched Spok Go, our software-as-a-service, cloud-native platform just over a year ago, at the onset of the pandemic. Despite unprecedented challenges, our team was able to generate initial sales of this platform in the second half of last year, and that momentum has carried into 2021. In the first quarter, we announced the international expansion of the Spok Go platform in Canada and Australia, with localized capabilities to meet compliance and language requirements. We also added two more Spok Go wins in these markets. We also made significant progress in clinical innovation partner development, collaborating with both Mayo Clinic and St. Joseph's Healthcare Hamilton to enhance the clinical optimization of the Spok Go platform. These partnerships are very valuable to us, as they are further evidence of the broad acceptance that our Spok Go platform is receiving and provide us insights from best-in-class organizations to enhance the capabilities of Spok Go.

"In the first quarter, we slightly grew software revenue, and our backlog was consistent with prior year levels. We believe these are significant milestones in our recovery to pre-pandemic operating performance, as it shows a comparison to the last quarter that was not materially impacted by COVID-19. Additionally, in the first quarter, we saw continued solid trends in our wireless business. We are focused on maintaining our cash, cash equivalents and short-term investments balances, and in the first quarter, we generated slightly positive cash flow from operations. We achieved these results while continuing to support our Spok Care Connect® platform and investing in Spok Go. Last year we implemented a furlough program designed to conserve cash, prevent layoffs and continue our investment while our healthcare customers struggled with the pandemic. We continued that plan into 2021 with across-the-board furloughs of one week in each of the 1st and 2nd quarters. We are ending furloughs after the second quarter and have no plans to continue them going forward," concluded Kelly.

Business Outlook:

Michael W. Wallace, chief operating officer and chief financial officer, said, "Disciplined expense management continues to be a key focus, as we further align expense levels with market demand for our products. During the first quarter, operating expenses were down nearly 9% and adjusted operating expenses were down more than 7% from prior year levels, with improvements in most expense categories over that period. Spok's balance sheet remains strong, as the cash, cash equivalents and short-term investments balance was $71.6 million at March 31, 2021 and we are still operating with no debt."

Regarding financial guidance for 2021, based on the increased visibility the Company has into the operating environment through the end of the year, and the discontinuance of the furlough program after the second quarter, Spok revised its 2021 financial guidance ranges. Spok's revised expectations are summarized in the following table:

(Unaudited and in millions)	Previous Guidance Full Year 2021					Current Guidance Full Year 2021
Revenue
Wireless	$	74.0	to	$	80.0	$	77.0	to	$	81.0

On April 14, 2021, in support of the Company's Board of Directors' ongoing annual refreshment process, Brian O'Reilly informed the Company that he will not stand for re-election to the Board at the Company's 2021 annual meeting of stockholders. Mr. O'Reilly will remain a director and maintain his committee memberships through the 2021 annual meeting. Royce Yudkoff, chairman of the board of directors, said, "On behalf of my fellow directors, I would like to thank Brian for his many years of leadership on the Board and the significant contributions he has made to the Company."

In addition, on June 1, 2021, the Company will publish its inaugural Environmental, Social, and Governance (ESG) Report, reflecting a continued commitment to advancing the Company's ESG goals and sustainable business practices.

Non-GAAP Financial Measures

This press release contains the following non-GAAP financial measures: adjusted operating expenses and adjusted EBITDA. Adjusted operating expenses excludes depreciation, amortization and accretion, and includes capitalized software development costs. Adjusted EBITDA represents net income/(loss) before interest income/expense, income tax expense/benefit, depreciation, amortization and accretion expense, stock based compensation expense, and includes capitalized software development costs.

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 do not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal of these non-GAAP financial measures is that they exclude significant expenses and income 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 expenses and income 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.
