Spok Holdings, Inc. (NASDAQ:SPOK), a global leader in healthcare communications, today announced results for the third quarter ended September 30, 2021. In addition, the Company's Board of Directors declared a regular quarterly dividend of $0.125 per share, payable on December 10, 2021, to stockholders of record on November 16, 2021.

Third Quarter 2021 Highlights:

Received record-level software maintenance renewal bookings of $12.1 million
Continued improvement in year-over-year pager unit erosion on a trailing twelve-month basis
Added further development enhancements to the Spok Go®platform
Introduced the ReadyCall® Text pager
For nine consecutive years, has partnered with all of the adult Best Hospitals, and in eight of the past nine years, provided solutions to all of the children's Best Hospitals named to U.S. News & World Report's 2021-22 Best Hospitals Honor Roll
Completed Eleventh Annual State of Healthcare Communications Survey
Subsequent to the end of the third quarter 2021, hosted annual Connect 21 Conference for customers in a virtual format

Management Commentary:

"We welcomed four new customers to the Spok family during the quarter of which three were software and one was wireless," said Vincent D. Kelly, president and chief executive officer. "Additionally, we successfully closed 12 six-figure deals from our pipeline. Software bookings were driven by strength in maintenance renewals, supporting our strong recurring revenue base. We added an additional Spok Go win during the quarter and remain encouraged by the size and quality of our pipeline, with the signing of three more Spok Go deals so far in the fourth quarter. We had continued improvement in year-over-year pager unit erosion on a trailing twelve-month basis, and software revenue was up in the third quarter of 2021 compared to the second quarter of 2021.

"During the third quarter 2021, we made several key product announcements, such as the newest version of Spok Go and the ReadyCall® Text pager to improve the patient experience. We also received recognition as a solutions provider to all 20 adult hospitals named to U.S. News & World Report's 2021-22 Best Hospitals Honor Roll and conducted our eleventh annual survey on the state of healthcare communications to more thoroughly understand the unique challenges facing clinicians, particularly in the current environment. Finally, subsequent to the end of the third quarter 2021, the Company held its annual Connect 21 Conference for customers on October 11-12, 2021, in a virtual format, which was well received by both current and prospective customers. Tim Tindle, Spok's Chief Information Officer, led a session on implementing a secure HIPAA-compliant messaging solution, using our new GenA™ pager, resulting in several new leads and orders. The success of the conference should create additional opportunities for 2022 and beyond," concluded Kelly.

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 and 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.

Safe Harbor Statement under the Private Securities Litigation Reform Act

Statements contained herein or in prior press releases which are not historical fact, such as statements regarding Spok's 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.
