UNAUDITED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
NOTE 1 - ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
Spok Holdings, Inc. (NASDAQ: SPOK) ("Spok," "we," "our" or the "Company"), through its wholly owned subsidiary Spok, Inc., is proud to be the global leader in healthcare communications. We deliver clinical information to care teams when and where it matters most to improve patient outcomes. Top hospitals rely on Spok products and services to enhance workflows for clinicians, support administrative compliance, and provide a better experience for patients.
We offer a focused suite of unified clinical communication and collaboration solutions that include call center applications, clinical alerting and notifications, one-way and advanced two-way wireless messaging services, mobile communications and public safety solutions.
We provide one-way and advanced two-way wireless messaging services, including information services, throughout the United States. These services are offered on a local, regional and nationwide basis employing digital networks. One-way messaging consists of numeric and alphanumeric messaging services. Numeric messaging services enable subscribers to receive messages that are composed entirely of numbers, such as a phone number, while alphanumeric messages may include numbers and letters, which enable subscribers to receive text messages. Two-way messaging services enable subscribers to send and receive messages to and from other wireless messaging devices, including pagers, personal digital assistants and personal computers. We also offer voice mail, personalized greetings, message storage and retrieval, and equipment loss and/or maintenance protection to both one-way and two-way messaging subscribers. These services are commonly referred to as wireless messaging and information services.
We also develop, sell and support enterprise-wide systems for hospitals and other organizations needing to automate, centralize and standardize clinical communications. These solutions are used for contact centers, clinical alerting and notification, mobile communications and messaging and for public safety notifications. These areas of market focus complement the market focus of our wireless services outlined above.
Basis of Presentation
The accompanying Condensed Consolidated Financial Statements include our accounts and the accounts of our wholly owned direct and indirect subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Our Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). In management's opinion, the unaudited Condensed Consolidated Financial Statements include all adjustments and accruals that are necessary for the presentation of the results of all interim periods reported herein and all such adjustments are of a normal, recurring nature, with the exception of the revision to deferred revenue as discussed in more detail below.
Amounts shown in the Condensed Consolidated Statements of Operations within the operating expense categories of cost of revenue; research and development; technology operations; selling and marketing; and general and administrative are recorded exclusive of depreciation and accretion. These items are shown separately to the extent that they are considered material for the periods presented.
The financial information included herein, other than the Condensed Consolidated Balance Sheet as of December 31, 2022, is unaudited. The Condensed Consolidated Balance Sheet as of December 31, 2022, has been derived from, but does not include all, the disclosures contained in the audited Consolidated Financial Statements as of and for the year ended December 31, 2022.
These Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and accompanying notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 Annual Report”). The Condensed Consolidated Statements of Operations for the interim periods presented are not necessarily indicative of the results that may be expected for a full year.
Revision of Previously Issued Financial Statements
In connection with the preparation of its financial statements for the quarter ended June 30, 2023, the Company identified certain adjustments to correct an immaterial error related to the understatement of deferred revenue of approximately $1.0 million. These adjustments corrected an overstatement of our software revenue in 2018 stemming from non-recurring activity associated with the implementation of a new financial system in 2017. Based on our quantitative and qualitative analysis, we concluded that the adjustments were not material to any prior annual or interim periods. As such, we have revised the Condensed Consolidated Balance Sheets for the year ended December 31, 2022, relevant footnotes, and

UNAUDITED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
other financial information as applicable, included herein to reflect the reduction in opening retained earnings and a corresponding increase to deferred revenue.
Use of Estimates
The preparation of these Condensed Consolidated Financial Statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. On an ongoing basis, we evaluate estimates and assumptions, including, but not limited to, those related to the impairment of long-lived assets, goodwill, accounts receivable allowances, revenue recognition, determining the standalone selling price of performance obligations, variable consideration, depreciation expense, asset retirement obligations and income taxes. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
NOTE 2 - RISKS AND OTHER IMPORTANT FACTORS
See “Item 1A. Risk Factors” of Part II of this Quarterly Report on Form 10-Q (“Quarterly Report”) and "Item 1A. Risk Factors" of Part I of the 2022 Annual Report, which describe key risks associated with our operations and industry.
NOTE 3 - RECENT ACCOUNTING STANDARDS
The Company considers the applicability and impact of all Accounting Standards Updates ("ASUs") issued by the Financial Accounting Standards Board ("FASB"). The Company has determined that all recent ASUs issued by the FASB are either not applicable or are not expected to have a material impact on the Company's Condensed Consolidated Financial Statements.
NOTE 4 - SIGNIFICANT ACCOUNTING POLICIES UPDATE
Our significant accounting policies are detailed in Note 1, “Organization and Significant Accounting Policies” of the 2022 Annual Report.
NOTE 5 - RESTRUCTURING
In February 2022, the Company announced a new strategic business plan that included a restructuring of its business to discontinue Spok Go, eliminate all associated costs and optimize the Company’s existing structure to drive continued cost improvement.
As part of the restructuring program, the Company eliminated 176 positions, primarily in research and development, and also in professional services, selling and marketing, and back-office support functions.
For the three and nine months ended September 30, 2022, the Company incurred total severance and restructuring costs of $1.5 million and $6.4 million respectively, related to the restructuring program, which are included within the Condensed Consolidated Statements of Operations. These costs are as follows:

| For the Three Months Ended September 30, | For the Nine Months Ended September 30,
(Dollars in thousands) | 2022 |  | 2022
Severance and personnel related costs | $ | 791 |  |  | $ | 5,137 |
Contractual terminations | 712 |  |  | $ | 1311 |
Total severance and restructuring costs | $ | 1,503 |  |  | $ | 6,448 |

As of June 30, 2023, there were no outstanding restructuring-related liabilities. A summary of activity for the six months ended June 30, 2023 and the nine months ended September 30, 2022, for restructuring-related liabilities associated with the strategic business plan, which is included within accrued compensation and benefits and other current liabilities within the Condensed Consolidated Balance Sheet, is as follows:

NOTE 6 - REVENUE, DEFERRED REVENUE AND PREPAID COMMISSIONS
Wireless Revenue
Wireless revenue consists of two primary components: paging revenue and product and other revenue. Paging revenue consists primarily of recurring fees associated with the provision of messaging services and fees for paging devices and is net of a provision for service credits. Product and other revenue reflects system sales, the sale of devices and charges for paging devices that are not returned and are net of anticipated credits. Our core offering includes subscriptions to one-way or two-way messaging services for a periodic (monthly, quarterly, semiannual, or annual) service fee. This is generally based upon the type of service provided, the geographic area covered, the number of devices provided to the customer and the period of commitment. A subscriber to one-way messaging services may select coverage on a local, regional or nationwide basis to best meet their messaging needs. Two-way messaging is generally offered on a nationwide basis. (See Item 1. “Business,” in the 2022 Annual Report for more details.)
Software Revenue
Software revenue consists of two primary components: operations revenue and maintenance revenue. Operations revenue consists primarily of license revenues for our healthcare communications solutions, revenue from the sale of equipment that facilitates the use of our software solutions, and professional services revenue related to the implementation of our solutions. Maintenance revenue is for ongoing support of our software solutions or related equipment and access to when-and-if available software updates. Maintenance is generally purchased and renewed on an annual basis.
Revenue Recognition
Revenues are recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services.

SPOK HOLDINGS, INC.
UNAUDITED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Our software licenses and hardware are generally recognized at a point in time when we have transferred control to the customer. For software licenses, revenue is not recognized until the related license(s) has been made available to the customer and the customer can begin to benefit from its right to use the license(s). Our software licenses represent a right to use Spok’s intellectual property ("IP") as it exists at a point in time at which the license is granted. Many of our software licenses have significant standalone functionality due to their ability to process a transaction or perform a function or task, and we do not need to maintain those products, once provided to the customer, for value to exist. While the functionality of the IP that we license may substantively change during the license period, customers are not contractually or practically required to update their license as a result of those changes.
Our wireless, professional services, and maintenance are generally recognized over time due to a customer's simultaneous receipt and consumption of the benefit as we perform the work. As we transfer control over time, we recognize revenue based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires significant judgment and is based on the nature of the products or services to be provided. Generally, we use the time-elapsed measure of progress for performance obligations that include wireless or maintenance services. We believe this method best depicts the simultaneous transfer and consumption of the benefit based on our performance as these services are generally considered standby services. For professional services, we leverage an input methodology based on the number of hours worked on a project versus the total expected hours necessary to complete the project. Revenues are recognized proportionally as hours are incurred.
The following table presents our revenues disaggregated by revenue type:

| For the Three Months Ended September 30, |  | For the Nine Months Ended September 30,

Deferred Revenues
Our deferred revenues represent payments made by, or due from, customers in advance of our performance. Changes in the balance of total deferred revenue during the nine months ended September 30, 2023, are as follows:

(Dollars in thousands) | December 31, 2022 |  | Additions |  | Revenue Recognized |  | September 30, 2023
Deferred Revenue | $ | 27,505 |  |  | $ | 44,910 |  |  | $ | (46,910) |  |  | $ | 25,505 |

During the nine months ended September 30, 2023, the Company recognized $21.3 million related to amounts deferred as of December 31, 2022.
Prepaid Commissions
Our prepaid commissions represent payments made to employees in advance of our performance on the related underlying contracts. These costs have been incurred directly in relation to obtaining a contract. As such, these costs are amortized over the estimated period of benefit. Changes in the balance of total prepaid commissions during the nine months ended September 30, 2023 are as follows:

(Dollars in thousands) | December 31, 2022 |  | Additions |  | Commissions Recognized |  | September 30, 2023
Prepaid Commissions | $ | 1,745 |  |  | $ | 4,102 |  |  | $ | (3,429) |  |  | $ | 2,418 |

Prepaid commissions are included within prepaid expenses in the Condensed Consolidated Balance Sheets and commissions expense is included within selling and marketing in the Condensed Consolidated Statements of Operations.
Remaining Performance Obligations
The balance of remaining performance obligations at September 30, 2023, was $58.7 million. We expect to recognize approximately $41.6 million of our remaining performance obligations over the next 12 months, with the remaining balance recognized thereafter.
NOTE 7 - LEASES
We have operating lease arrangements for corporate offices, cellular towers, storage units and small building space. The building space is used to house infrastructure, such as transmitters, antennae and other various equipment for the Company’s wireless paging services. For leases with a term of 12 months or less, renewal terms are generally of an evergreen nature (either month-to-month or year-to-year). For leases with a term greater than 12 months, renewal terms are generally explicit and provide for one to five optional renewals consistent with the initial term. Many of our leases, with the exception of those for our corporate offices, include options to terminate the lease within one year. Variable lease payments, residual value guarantees or purchase options are not generally present in these leases.
In May 2022, we extended 23 site leases on a Master License Agreement which included a term of 10 years with an option to terminate within 45 days of notification of termination. At that time, we recorded a $2.9 million right-of-use asset and a corresponding operating lease liability for these leases.
In December 2022, we modified an office lease to reduce the leased space and optimize costs, which resulted in a reduction of $1.8 million in right-of-use assets and corresponding operating lease liabilities.
In September 2023, we exercised an early termination option for the lease of our corporate headquarters in Alexandria, Virginia. Upon exercising the option, the lease term was reduced by two years, with a revised end date of September 30, 2024. As a result of the early termination, the Company paid a one-time termination fee of $0.7 million, reflected in our cash balances as of September 30, 2023. A reduction of $1.3 million was made to right-of-use of assets and a corresponding reduction of $2.0 million was made to non-current operating lease liabilities. For additional details, please refer to our discussion on this topic under "Liquidity and Capital Resources" within the Management's Discussion and Analysis of Financial Condition and Results of Operations.
Lease costs are included in technology operations and general and administrative expenses in the Condensed Consolidated Statements of Operations. The following table presents lease costs disaggregated by type:

NOTE 9 - GOODWILL
During the three months ended September 30, 2023, we performed a qualitative assessment of goodwill and determined that a triggering event had not occurred. While an impairment assessment is performed annually in the fourth quarter, the Company monitors its business environment for potential triggering events on a quarterly basis. There is potential for further impairment charges being recognized in future periods based on these ongoing assessments.

The short-term portion of the balance above is included within other current liabilities in the Condensed Consolidated Balance Sheets as of September 30, 2023, and December 31, 2022.
The cost associated with the estimated removal costs and timing refinements due to ongoing network rationalization activities is expected to accrete to a total liability of $9.1 million. The total estimated liability is based on the transmitter locations remaining after we have consolidated the number of networks we operate and assuming the underlying leases continue to be renewed to that future date. Accretion expense related solely to asset retirement obligations and was recorded based on the interest method.
NOTE 11 - STOCKHOLDERS' EQUITY

Common Stock Repurchase Program
On February 16, 2022, our Board of Directors authorized a share repurchase program for up to $10 million of the Company’s common stock. Under the repurchase program, repurchases can be made from time to time using a variety of methods, which may include open market purchases, privately negotiated transactions or otherwise, all in accordance with the rules of the SEC and other applicable legal requirements. The specific timing, price and size of purchases will depend on prevailing stock prices, general economic and market conditions, legal requirements and other considerations. The repurchase program does not obligate the Company to acquire any particular amount of common stock, and the repurchase program may be suspended or discontinued at any time at the Company’s discretion. For the nine months ended September 30, 2023, we did not repurchase any common stock.

Net Income (Loss) per Common Share
Basic net income (loss) per common share is computed on the basis of the weighted average common shares outstanding. Diluted net income (loss) per common share is computed on the basis of the weighted average common shares outstanding plus the effect of all potentially dilutive common shares, including outstanding restricted stock and RSUs, which are treated as contingently issuable shares, using the “treasury stock” method.
The components of basic and diluted net income (loss) per common share were as follows for the periods stated:

Stock-Based Compensation Plans
On April 29, 2020, our Board of Directors adopted the Spok Holdings, Inc. 2020 Equity Incentive Award Plan (the “2020 Equity Plan”) that our stockholders subsequently approved on July 28, 2020. At July 28, 2020, a total of 1,699,950 shares of common stock had been reserved for issuance under the Equity Plans.
On April 10, 2023, our Board of Directors adopted an amendment and restatement of the Spok Holdings, Inc. 2020 Equity Incentive Award Plan (the “2020 Equity Plan”) to increase the number of shares available for issuance by 1,000,000 shares that our stockholders subsequently approved on July 25, 2023. At July 25, 2023, a total of 1,268,444 shares of common stock had been reserved for issuance under the Equity Plans.
Awards under the 2020 Equity Plan may be in the form of stock options, restricted common stock, RSUs, performance awards, dividend equivalents, stock payment awards, deferred stock, DSUs, stock appreciation rights or other stock or cash-based awards.
Restricted stock awards generally vest one year from the date of grant. Related dividends accumulate during the vesting period and are paid at the time of vesting.
Contingent RSUs generally vest over a three-year performance period upon successful completion of the performance objectives. Non-contingent RSUs generally vest in thirds, annually, over a three-year period. Dividend equivalent rights generally accompany each RSU award and those rights accumulate and vest along with the underlying RSU.
17

SPOK HOLDINGS, INC.
UNAUDITED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Dividend equivalent rights generally accompany each DSU award and are paid to participants in cash on the Company's applicable dividend payment date whether the DSU is vested or unvested. The dividend equivalent right associated with a DSU continues until delivery of the underlying shares of common stock is made.
Payment of the underlying shares of common stock occurs at the earliest of a participant's separation from service, disability, death, or a change in control.
The following table summarizes the activities under the Equity Plans from January 1, 2023, through September 30, 2023:

| Activity
Total equity securities available at January 1, 2023 | 683,052 |
Additional shares available for issuance under the amended and restated 2020 Equity Plan | 1,000,000 |
RSU, DSU, and restricted stock awarded to eligible employees, net of forfeitures | (398,588) |
Total equity securities available at September 30, 2023 | 1,284,464 |

The following table details activities with respect to outstanding RSUs, DSUs, and restricted stock under the Equity Plans for the nine months ended September 30, 2023:

| Shares |  | Weighted Average Grant Date Fair Value
Unvested at January 1, 2023 | 1,015,749 |  |  | $ | 10.25 |

Forfeited | (63,924) |  |  | 10.28 |
Unvested at September 30, 2023 | 1,036,651 |  |  | $ | 9.06 |

Of the 1,036,651 unvested RSUs, DSUs and restricted stock outstanding at September 30, 2023, 533,494 RSUs include contingent performance requirements for vesting purposes. At September 30, 2023, there was $3.5 million of unrecognized net compensation cost related to RSUs and restricted stock, which is expected to be recognized over a weighted average period of 1.7 years.
Employee Stock Purchase Plan
In 2016, our Board of Directors adopted the Spok Holdings, Inc. Employee Stock Purchase Plan (the "ESPP") that our stockholders subsequently approved on July 25, 2016. A total of 250,000 shares of common stock were reserved for issuance under this plan.
The ESPP allows employees to purchase shares of common stock at a discounted rate, subject to plan limitations. Under the ESPP, eligible participants can voluntarily elect to have contributions withheld from their pay for the duration of an offering period, subject to the ESPP limits. At the end of an offering period, contributions will be used to purchase the Company's common stock at a discount to the market price based on the first or last day of the offering period, whichever is lower.
Participants are required to hold common stock for a minimum period of two years from the grant date. Participants will begin earning dividends on shares after the purchase date. Each offering period will generally last for no longer than six months. Once an offering period begins, participants cannot adjust their withholding amount. If a participant chooses to withdraw, any previously withheld funds will be returned to the participant, with no stock purchased, and that participant will be eligible to participate in the ESPP during the next offering period. If the participant terminates employment with the Company during the offering period, all contributions will be returned to the employee and no stock will be purchased.
The Company uses the Black-Scholes model to calculate the fair value of the common stock to be purchased during each offering period on the offer date. The Black-Scholes model requires the use of estimates for the expected term, the expected volatility of the underlying common stock over the expected term, the risk-free interest rate and the expected dividend payment.

NOTE 12 - INCOME TAXES
Spok files a consolidated U.S. federal income tax return and income tax returns in various state, local and foreign jurisdictions as required.
Our quarterly tax provision and our quarterly estimate of our annual effective tax rate are subject to significant variation due to several factors, including variability in accurately predicting our pre-tax and taxable income and loss and the mix of jurisdictions to which they relate, changes in how we do business, changes in our stock price, foreign currency gains (losses), tax law developments (including changes in statutes, regulations, case law, and administrative practices), and relative changes of expenses or losses for which tax benefits are not recognized. Additionally, our effective tax rate can be more or less volatile based on the amount of pre-tax income or loss. For example, the impact of discrete items and non-deductible expenses on our effective tax rate is greater when our pre-tax income is lower.
For 2023, the anticipated effective income tax rate is expected to continue to differ from the federal statutory rate of 21%, primarily due to the effect of state income taxes, permanent differences between book and taxable income, and certain discrete items.
We had total net deferred income tax assets ("DTAs") of $47.0 million and $52.4 million as of September 30, 2023, and December 31, 2022, respectively. We had a valuation allowance of $2.3 million as of both September 30, 2023, and December 31, 2022.
We assess the recoverability of our deferred income tax assets, which represent the tax benefits of future tax deductions, based on available positive and negative evidence and by considering the adequacy of future taxable income from all sources, including prudent and feasible tax planning strategies. This assessment is required to determine whether, based on all available evidence, it is "more likely than not" (meaning a probability of greater than 50%) that all or some portion of the deferred income tax assets will be realized in future periods. During the fourth quarter of each year, we update our multi-year forecast of taxable income for our operations, which assists in analyzing the recoverability of our DTAs.

SPOK HOLDINGS, INC.
UNAUDITED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
The Company maintains a valuation allowance related to Federal Foreign Tax Credits and certain net operating losses and state tax credits, as we do not believe current projections of future taxable income will be sufficient to utilize those tax assets prior to expiration.
NOTE 13 - COMMITMENTS AND CONTINGENCIES
There have been no material changes during the nine months ended September 30, 2023, to the commitments and contingencies previously reported in the 2022 Annual Report.
NOTE 14 - RELATED PARTIES
A member of our Board of Directors, who was appointed at the beginning of 2020, serves as EVP and Chief Information Officer for an entity that is also a customer of the Company.

Business
See Note 1, "Organization and Significant Accounting Policies" in Item 1 of Part I of this Quarterly Report and Item 1. "Business" of Part I of the 2022 Annual Report, which describe our business in further detail.
Strategic Business Plan
In February 2022, our Board of Directors announced a new strategic business plan that included a restructuring of our business to discontinue Spok Go and eliminate all associated costs and optimize the Company’s existing structure to drive continued cost improvement. The strategic business plan included a renewed focus on our existing and established business, including the Spok Care Connect Suite and our wireless service offerings. These restructuring efforts were completed during the fourth quarter of 2022. As a result of the implementation of the plan, we eliminated 176 positions, primarily in research and development, and also in professional services, selling and marketing, and back-office support functions. These actions allowed us to better align costs and, as a result, return capital to stockholders in the form of increased quarterly dividends of $0.3125 per share starting in 2022. We will continue to focus on optimizing costs to allow us to prioritize cash flow generation and the return of capital to stockholders.
Further details can be found in Note 5 "Restructuring" in the Notes to Condensed Consolidated Financial Statements.

Revenue
We offer a focused suite of unified clinical communications and collaboration solutions that include call center applications, clinical alerting and notifications, one-way and advanced two-way wireless messaging services, mobile communications and public safety solutions.
We develop, sell and support enterprise-wide systems for healthcare, government, large enterprise and other organizations needing to automate, centralize and standardize their approach to clinical communications and collaboration. Our solutions can be found in prominent hospitals, large government agencies, leading public safety institutions, colleges and universities, large hotels, resorts and casinos, and well-known manufacturers. Our primary market is the healthcare provider industry, particularly hospitals. While we have historically identified hospitals with 200 or more beds as the primary targets for our software solutions, as well as our paging services, we have expanded our focus to include smaller hospitals with shorter sales cycles, including academic medical centers.
Revenue generated by wireless messaging services (including voice mail, personalized greeting, message storage and retrieval), equipment, maintenance plans and/or equipment loss protection for both one-way and two-way messaging subscribers is presented as wireless revenue in our Condensed Consolidated Statements of Operations. Revenue generated by the sale of our software solutions, which includes software license, professional services (installation, consulting and training), equipment (to be used in conjunction with the software), and post-contract support (ongoing maintenance), is presented as software revenue in our Condensed Consolidated Statements of Operations. Our software is licensed to end users under an industry standard software license agreement.
Refer to Note 6, "Revenue, Deferred Revenue and Prepaid Commissions" in the Notes to Condensed Consolidated Financial Statements for additional information on our wireless and software revenue streams.

Wireless Revenue
Wireless revenue is generally reflective of the number of units in service and measured monthly as Average Revenue Per User ("ARPU"). On a consolidated basis, ARPU is affected by several factors, including the mix of units in service and the pricing of the various components of our services. The number of units in service changes based on subscribers added, referred to as gross placements, less subscriber cancellations, or disconnects.
The decrease in wireless revenue for the three months ended September 30, 2023, compared to the same period in 2022, reflects the secular decrease in our wireless units in service, from 824 thousand as of September 30, 2022 to 785 thousand as of September 30, 2023. This was partially offset by an increase in the standard rate within ARPU, as a result of price increases initiated in September of 2023. ARPU was $7.59 for the three months ended September 30, 2023, as compared to $7.40 for the same periods in 2022.
23

The increase in wireless revenue for the nine months ended September 30, 2023, compared to the same period in 2022, continues to reflect increases in ARPU as a result of price increases initiated in the latter part of 2022, as well as the price changes initiated in September of 2023, and general increases in Universal Service Fees ("USF"). ARPU was $7.62 for the nine months ended September 30, 2023, as compared to $7.30 for the same period in 2022. Excluding pass-through items, ARPU increased by $0.23, as compared to the same period in 2022, as a result of the price increases. These were partially offset by the secular decrease in demand for our wireless units in service, as noted above.
We believe that demand for wireless services will continue to decline for the foreseeable future in line with recent trends, as our wireless products and services are replaced with other competing technologies, such as the shift from narrowband wireless service offerings to broadband technology services.
The following reflects the impact of subscribers and ARPU on the change in paging revenue:

|  |  |  | For the Three Months Ended September 30, |  | Change Due To:
(in thousands) |  |  |  |  |  |  |  | 2023 |  | 2022 |  | Change |  | ARPU |  | Units
Paging revenue |  |  |  |  |  |  |  | $ | 18,119 |  |  | $ | 18,419 |  |  | $ | (300) |  |  | $ | 453 |  |  | $ | (754) |
|  |  |  | For the Nine Months Ended September 30, |  | Change Due To:
(in thousands) |  |  |  |  |  |  |  | 2023 |  | 2022 |  | Change |  | ARPU |  | Units
Paging revenue |  |  |  |  |  |  |  | $ | 54,915 |  |  | $ | 54,873 |  |  | $ | 42 |  |  | $ | 2,336 |  |  | $ | (2,295) |

As demand for one-way and two-way messaging has declined, we have developed or added service offerings such as encrypted paging and Spok Mobile with a pager number to increase our revenue potential. These service offerings, along with the nominal increases in the standard rate, are designed to mitigate the decline in our wireless revenue. We will continue to explore ways to innovate and provide customers with the highest value possible.
In late 2021, we began offering our newest pager, GenA. This one-way alphanumeric pager features a high resolution ePaper display, intuitive modern user interface, advanced encryption and security features, over-the-air remote programming, and an antimicrobial housing. Users can select from various font sizes, and the large GenA display also leverages proportional fonts to maximize key information on a single screen.
The GenA pager is the only product available on the market with these capabilities, and we maintain an exclusive arrangement with the product's manufacturer. Given the product differentiation of the GenA pager, its development is a key initiative providing a competitive advantage, and we expect this new technology will be popular with our customers in clinical environments and may help slow our wireless revenue attrition.
Software Revenue
Software revenue consists of two components: operations revenue and maintenance revenue. Operations revenue consists primarily of license revenues for our healthcare communications solutions, revenue from the sale of equipment that facilitates the use of our software solutions, and professional services revenue related to the implementation of our solutions. Maintenance revenue is generated from our ongoing support of our software solutions or related equipment, typically for a period of one year after project completion.
To a large degree, software revenue corresponds to our backlog of performance obligations ready to deliver at some point in the future, and any delays in implementation may affect the timing of revenue recognition. Our software projects generally originate from fixed-bid contracts, although many involve a protracted sales cycle and may result in unforeseen complexity and deviation from the original scope. The time needed to complete projects, therefore, may not align with our original expectations, which affects our backlog. As a result, software revenue may fluctuate on a short-term basis, and we generally evaluate longer-term trends when managing this business.
Operations Revenue
Software operations revenue increased during the three and nine months ended September 30, 2023, when compared to the same periods in 2022. This increase in revenue was primarily due to license, professional services and equipment revenue. License and equipment revenue increases were driven by higher operations bookings as compared to the same periods in 2022. Professional services revenue increased primarily as a result of improvements in resource utilization.
24

Maintenance Revenue
For the three months ended September 30, 2023, maintenance revenue increased compared to the same period in 2022, as a result of certain one-time revenue benefits during the three months ended September 30, 2023 that were not incurred in the year prior, as well as in addition to improvement in gross churn.
For the nine months ended September 30, 2023, compared to the same period in 2022, maintenance revenue continues to decline at a slower pace than seen over the last several years. While the deterioration of maintenance revenue from new license bookings continues to create an environment where churn is greater than the inflow of new revenue, our gross churn rates are improving.
While we have seen some improvement in our normal customer churn, our ability to replace this churn with new revenues will not likely replicate what we have accomplished historically nor do we expect to fully offset this with annual increases of our existing base. Given these dynamics, we believe annual maintenance revenue is likely to continue decreasing, albeit at a slowing pace, until such time that we are able to enhance our existing software solutions, which would provide an avenue to sell additional licenses generating new maintenance revenue, as well as reduce levels of gross churn.
Operating Expenses
Our operating expenses are presented in functional categories. Certain of our functional categories are especially important to overall expense control and management. These operating expenses are categorized as follows:
•Cost of Revenue. These are expenses we incur for the delivery of products and services to our customers and consist primarily of hardware, third-party software, outside services expenses and payroll and related expenses for our professional services, logistics, customer support and maintenance staff.
•Research and Development. These expenses relate primarily to the development of new software products and the ongoing maintenance and enhancement of existing products. This classification consists primarily of employee payroll and related expenses, outside services related to the design, development, testing and enhancement of our solutions and to a lesser extent hardware equipment. Research and development expenses exclude any development costs that qualify for capitalization.
•Technology Operations. These are expenses associated with the operation of our paging networks. Expenses consist largely of site rent expenses for transmitter locations, telecommunication expenses to deliver messages over our paging networks, and payroll and related expenses for our engineering and pager repair functions. We actively pursue opportunities to consolidate transmitters and other service, rental and maintenance expenses in order to maintain an efficient network while simultaneously ensuring adequate service for our customers. We believe continued reductions in these expenses will occur for the foreseeable future as we continue to consolidate our networks, although the benefits of such network rationalization efforts and resulting costs savings will continue to decline.
•Selling and Marketing. The sales and marketing staff are involved in selling our communication solutions primarily in the United States. These expenses support our efforts to maintain gross placements of units in service, which mitigated the impact of disconnects on our wireless revenue base, and to identify business opportunities for additional or future software sales. We maintain a centralized marketing function that is focused on supporting our products and vertical sales efforts by strengthening our brand, generating sales leads and facilitating the sales process. These marketing functions are accomplished through targeted email campaigns, webinars, regional and national user conferences, monthly newsletters and participation at industry trade shows. Expenses consist largely of payroll and related expenses, commissions and other costs such as travel and advertising costs.
•General and Administrative. These are expenses associated with information technology and administrative functions, including finance and accounting, human resources and executive management. This classification consists primarily of payroll and related expenses, outside services expenses, taxes, licenses and permit expenses, and facility rent expenses.
•Depreciation, Amortization and Accretion. These are expenses that may be associated with one or more of the aforementioned functional categories. This classification generally consists of depreciation from capital expenditures or other assets that are core to our ongoing operations, amortization of intangible assets, amortization of capitalized software development costs, and accretion of asset retirement obligations.

For the nine months ended September 30, 2023, cost of revenue decreased compared to the same period in 2022, primarily driven by decreases in payroll and related, cost of sales, and partially offset by an increase in recoverable taxes and fees.
The decrease in payroll and related expenses is attributable to the restructuring activities and the related elimination of positions. Cost of sales expenses decreased primarily due to a reduction in third-party professional services utilized to augment company resources when short-term capacity constraints exist. Recoverable taxes and fees increased due to the rate change for USF fees, as established by the Federal Communications Commission on a quarterly basis. These fees are passed through to our wireless customer base and have a corresponding revenue impact.
Research and Development
Research and development expenses consisted of the following items:

| For the Three Months Ended September 30, |  | Change |  | For the Nine Months Ended September 30, |  | Change
(Dollars in thousands) | 2023 |  | 2022 |  | Total |  | % |  | 2023 |  | 2022 |  | Total |  | %

For the three months ended September 30, 2023, research and development expenses increased compared to the same period in 2022, primarily driven by an increase in payroll and related expenses as a result of higher average cost per employee. For the nine months ended September 30, 2023, research and development expenses decreased compared to the same periods in 2022, primarily driven by the decision to discontinue Spok Go in February 2022 and the resulting elimination of positions and associated outside services.

Technology Operations
Technology operations expenses consisted primarily of the following items:

| For the Three Months Ended September 30, |  | Change |  | For the Nine Months Ended September 30, |  | Change

FTE Employees | 69 |  |  | 78 |  |  | (9) |  |  | (11.5) | % |  |  |  |  |  |  |  |

For the three and nine months ended September 30, 2023, technology operations expenses decreased compared to the same periods in 2022, primarily due to a reduction in site rent expenses as a result of network rationalization efforts and payroll and related expenses attributable to the restructuring activities and the related elimination of positions. As a result of our network rationalization efforts, site rent and telecommunications costs decreased in response to a 3.2% decline in active transmitters from September 30, 2022 to September 30, 2023. As we reach certain minimum frequency commitments, as outlined by the United States Federal Communications Commission, we may be unable to continue our efforts to rationalize and consolidate our networks.
Selling and Marketing
Selling and marketing expenses consisted of the following items:

| For the Three Months Ended September 30, |  | Change |  | For the Nine Months Ended September 30, |  | Change

FTE Employees | 67 |  |  | 59 |  |  | 8 |  |  | 13.6 | % |  |  |  |  |  |  |  |

For the three months ended September 30, 2023, selling and marketing expenses increased compared to the same period in 2022, driven primarily by increases in payroll due to increase in headcount and commissions related to greater revenue. For the nine months ended September 30, 2023, selling and marketing expenses decreased compared to the same period in 2022, driven primarily by decreases in payroll and related expenses, advertising and events, and partially offset by an increase in commissions related to greater revenue.
Payroll and related expenses declined for the nine months ended September 30, 2023, largely due to restructuring activities and the related elimination of positions announced in February 2022.
The decrease in advertising and events expenses for the nine months ended September 30, 2023, largely reflects a decrease in costs spent related to trade show participation as compared to the same period in 2022.

For the three and nine months ended September 30, 2023, general and administrative expenses decreased compared to the same periods in 2022, primarily driven by decreases in outside services, facility rent, office and technology costs and bad debt. Payroll and related expenses increased for the three months ended September 30, 2023 and decreased for the nine months ended September 30, 2023.
Outside services decreased due to decreases in legal and other professional services for the three and nine months ended September 30, 2023.
The decreases in facility rent, office and technology costs were primarily due to a reduction in office space for the three and nine months ended September 30, 2023.
The decreases in bad debt were driven by improvements in collections on aging receivables for the three and nine months ended September 30, 2023.
Payroll and related expenses increased for the three months ended September 30, 2023, due to an increase in average cost per employee. Payroll and related expenses decreased for the nine months ended September 30, 2023, largely due to restructuring activities and the related elimination of positions announced in February 2022.
Depreciation and Accretion
For the three months ended September 30, 2023, and 2022, depreciation and accretion expenses were $1.3 million and $0.8 million, respectively. For the nine months ended September 30, 2023, and 2022, depreciation and accretion expenses were $3.8 million and $2.6 million, respectively. These expenses increased for the three and nine months ended September 30, 2023, compared to the same periods in 2022, primarily due to increases in asset retirement cost and pager depreciation.
Severance and Restructuring
For the three months ended September 30, 2023, and 2022, we incurred severance and restructuring expenses of $0.1 million and $1.5 million, and for the nine months ended September 30, 2023, and 2022 we incurred $0.2 million and $6.4 million respectively. The costs incurred in 2022 related to the restructuring program announced in February 2022. No similar severance and restructuring expenses were incurred for the three and nine months ended September 30, 2023 as the restructuring program reached its conclusion in the fourth quarter of 2022.
28

Income Taxes
Provision for income taxes was $2.0 million and $0.8 million for the three months ended September 30, 2023 and 2022, respectively. Provision for income taxes was $5.7 million and $0.1 million for the nine months ended September 30, 2023 and 2022, respectively. Provision for income taxes changed for the three and nine months ended September 30, 2023 compared to the same periods in 2022 primarily due to the generation of pre-tax book income as compared to a pre-tax book loss, along with the effect of the anticipated annual effective tax rate change resulting from certain permanent tax differences, estimated research and development tax credits and related valuation allowance, and certain discrete items. Further details can be found in Note 12, "Income Taxes" in the Notes to Condensed Consolidated Financial Statements.
Liquidity and Capital Resources
Cash and Cash Equivalents
As of September 30, 2023, we held cash and cash equivalents of $27.3 million. The available cash and cash equivalents consist of cash in our operating accounts and cash invested in interest-bearing funds managed by third-party financial institutions. The Company maintains a majority of its cash and cash equivalents in accounts with major U.S. and multi-national financial institutions, and the majority of our deposits at these institutions exceed insured limits. Market conditions can impact the viability of these institutions. In the event of failure of any of the financial institutions where we maintain our cash and cash equivalents, there can be no assurance that we would be able to access uninsured funds in a timely manner or at all. Any inability to access or delay in accessing these funds could adversely affect our business, financial condition and results of operations.
Cash Sources
Our primary sources of liquidity have been our cash flows generated from operations and existing cash and cash equivalents. We maintain a level of liquidity sufficient to allow us to meet our cash needs in both the short term (next 12 months) and long term (beyond 12 months). At any point in time, we maintain approximately $5.0 million to $10.0 million in our operating accounts at third-party financial institutions. While we monitor daily the cash balances in our operating accounts and adjust the cash balances as appropriate, these cash balances could be impacted if the underlying financial institutions fail or are subject to other adverse conditions in the financial markets. To date, we have experienced no loss or lack of access to cash in our operating accounts.
Cash Uses
We intend to use our cash on hand to provide working capital, to support operations, to invest in our business, and to return value to stockholders through cash dividends and repurchases of our common stock. We may also consider using cash to fund or complete opportunistic investments and acquisitions that we believe will provide a measure of growth or revenue stability while supporting our existing operations. As a result of our discontinuation of Spok Go, we will no longer invest heavily in its development, and, as a result, we anticipate that we will have more cash available for other uses than in prior years.
On February 16, 2022, the Board authorized a share repurchase program for up to $10 million of the Company’s common stock. Under the repurchase program, repurchases can be made from time to time using a variety of methods, which may include open market purchases, privately negotiated transactions or otherwise, all in accordance with the rules of the SEC and other applicable legal requirements. The specific timing, price and size of purchases will depend on prevailing stock prices, general economic and market conditions, legal requirements and other considerations. The repurchase program does not obligate the Company to acquire any particular amount of common stock, and the repurchase program may be suspended or discontinued at any time at the Company’s discretion.
With the successful completion of the restructuring plan and our ongoing efforts to stabilize revenue and optimize costs, we anticipate positive cash flow generation will continue in future operating periods.
In September 2023, we exercised an early termination option for the lease of our corporate headquarters in Alexandria, Virginia. Upon exercising the option, the lease term was reduced by two years, with a revised end date of September 30, 2024. As a result of the early termination, the Company paid a one-time termination fee of $0.7 million, reflected in our cash balances as of September 30, 2023. A reduction of $1.3 million was made to operating lease right-of-use assets and a corresponding reduction of $2.0 million was made to non-current operating lease liabilities. The termination fee and remaining lease costs, totaling approximately $1.3 million will be amortized to Severance and Restructuring over the remaining lease term between October 1, 2023 and September 30, 2024. Thereafter, we expect to save approximately $1.0 million annually as a result of this lease termination.
29

The Company anticipates relocation of its headquarters to the existing corporate location in Plano, Texas and does not expect material costs to be incurred as a result of this change. Approximately 30 employees will be impacted as a result of this decision. While these employees will formally transition to a remote work environment, this is largely consistent with how we have been operating since the onset of the COVID-19 pandemic in early 2020. While this decision was not made lightly, the Company expects to benefit greatly from the significant cash savings, greater flexibility for our employees and higher levels of productivity we have seen from the pre-existing work-from-home posture.
Cash Flows Overview
In the event that net cash provided by operating activities and cash on hand are not sufficient to meet future cash requirements, we may be required to reduce planned capital expenses, reduce or eliminate our cash dividends to stockholders, not repurchase shares of our common stock under the share repurchase program, sell assets or seek additional financing. We can provide no assurance that reductions in planned capital expenses or proceeds from asset sales would be sufficient to cover shortfalls in available cash or that outside financing would be available on acceptable terms.
Based on current and anticipated levels of operations, we anticipate that net cash provided by operating activities, together with the available cash on hand at September 30, 2023, should be adequate to meet our anticipated cash requirements for the short term (next 12 months) and long term (beyond 12 months).
The following table sets forth information on our net cash flows from operating, investing, and financing activities for the periods stated:

|  | Nine Months Ended September 30, |  | Change
(Dollars in thousands) |  | 2023 |  | 2022 |
Net cash provided by (used in) operating activities |  | $ | 14,396 |  |  | $ | (148) |  |  | $ | 14,544 |
Net cash (used in) provided by investing activities |  | (2,419) |  |  | 13,260 |  |  | (15,679) |
Net cash used in financing activities |  | (20,559) |  |  | (20,058) |  |  | (501) |

Operating Activities
As discussed above, we are dependent on cash flows from operating activities to meet our cash requirements. Cash from operations varies depending on changes in various working capital items, including deferred revenues, accounts payable, accounts receivable, prepaid expenses and various accrued expenses.
For the nine months ended September 30, 2023, net cash provided by operating activities was $14.4 million primarily due to the net income of $12.3 million, changes in accounts receivable of $1.3 million, depreciation, amortization and accretion of $3.8 million, deferred income tax expense of $5.6 million and stock-based compensation of $2.7 million. This was partially offset by changes in accounts payable, accrued liabilities and other of $7.4 million, deferred revenue of $2.0 million, net operating lease liabilities of $1.2 million and prepaid expenses and other assets of $1.1 million.
For the nine months ended September 30, 2022, net cash used in operating activities was $0.1 million primarily due to a net loss of $2.4 million, changes in accounts payable, accrued liabilities and other of $3.1 million, accounts receivable $1.3 million, and in prepaid expenses and other assets of $1.0 million. This was partially offset by changes in stock-based compensation of $3.0 million, depreciation and accretion of $2.6 million, and provision for credit losses, service credits and other of $1.2 million.
Investing Activities
For the nine months ended September 30, 2023 and 2022, net cash used in investing activities was $2.4 million and net cash provided was $13.3 million, respectively. Net cash used in investing activities reflects purchases of property and equipment. For the nine months ended September 30, 2022, the net cash provided reflects the purchase and maturity of short-term investments offset by purchases of property and equipment.
Financing Activities
For the nine months ended September 30, 2023, and 2022, net cash used in financing activities was $20.6 million and $20.1 million, respectively, primarily due to cash distributions to stockholders and the purchase of common stock for tax withholding purposes on vested equity awards.

On October 25, 2023, our Board of Directors declared a regular quarterly cash dividend of $0.3125 per share of common stock with a record date of November 16, 2023, and a payment date of December 8, 2023. This cash dividend of approximately $6.2 million, applicable to our common stock outstanding, will be paid from available cash on hand.
Commitments and Contingencies
In the ordinary course of our operations, we enter into certain contractual obligations. Such obligations include data processing services, operating leases for premises and equipment, agreements with respect to borrowed funds and deposit liabilities.
Purchase obligations are defined as agreements to purchase goods or services that are enforceable, legally binding, non-cancelable, have a remaining term in excess of one year and that specify all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum or variable pricing provisions; and the approximate timing of transactions. The amounts of such obligations are based on our contractual commitments, however, it is possible that we may be able to negotiate lower payments if we choose to exit these contracts before their expiration date.
Our contractual payment obligations for operating leases apply to leases for office space and transmitter locations. Substantially all of these leases have lease terms ranging from one month to five years. We continue to review our office and transmitter locations and intend to replace, reduce or consolidate leases where possible. As we reach certain minimum frequency commitments, as outlined by the United States Federal Communications Commission, we may be unable to continue our efforts to rationalize and consolidate our networks.
We do not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As such, we are not exposed to any financing, liquidity, market or credit risk that may have arisen if we had engaged in such relationships.
The Company evaluates contingencies on an ongoing basis and establishes loss provisions for matters in which losses are probable and the amount of loss can be reasonably estimated.
The following table provides the Company's significant commitments and contractual obligations as of September 30, 2023:

|  | Payments Due by Period
(Dollars in thousands) |  | Total |  | 1 year or Less |  | 1 to 3 years |  | 3 to 5 years |  | More than 5 years
Operating lease obligations |  | $ | 14,542 |  |  | $ | 1,540 |  |  | $ | 7,021 |  |  | $ | 3,362 |  |  | $ | 2,619 |
Unconditional purchase obligations |  | 4,160 |  |  | 2,386 |  | 1,772 |  |  | 2 |  |  | — |
Total contractual obligations |  | $ | 18,702 |  |  | $ | 3,926 |  |  | $ | 8,793 |  |  | $ | 3,364 |  |  | $ | 2,619 |

Critical Accounting Policies and Estimates
The preceding discussion and analysis of financial condition and operations is based on our Condensed Consolidated Financial Statements, which have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of our Condensed Consolidated Financial Statements requires management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosures. On an ongoing basis, we evaluate estimates and assumptions, including, but not limited to, those related to the impairment of long-lived assets and intangible assets subject to amortization and goodwill, accounts receivable, revenue recognition, asset retirement obligations, and income taxes. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
There have been no changes to the critical accounting policies reported in the 2022 Annual Report that affect our significant judgments and estimates used in the preparation of our Condensed Consolidated Financial Statements.
ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Interest Rate Risk
As of September 30, 2023, we had no outstanding debt and no revolving credit facility.
Foreign Currency Exchange Rate Risk
We conduct a limited amount of business outside the United States. The financial impact of transactions billed in foreign currencies is immaterial to our financial results and, consequently, we do not have any material exposure to the risk of foreign currency exchange rate fluctuations.
ITEM 4. CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
Our management carried out an evaluation, as required by Rule 13a-15(b) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), with the participation of our principal executive officer and our principal financial officer, of the effectiveness of our disclosure controls and procedures, as of the end of our last fiscal quarter. Disclosure controls and procedures are defined under Rule 13a-15(e) under the Exchange Act as controls and other procedures of an issuer that are designed to ensure that the information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act (i) is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and (ii) is accumulated and communicated to the issuer’s management, including its principal executive officer and principal financial officer, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure. Based upon this evaluation, our principal executive officer and our principal financial officer have concluded that our disclosure controls and procedures were effective as of September 30, 2023.
