Revolving Credit Facility

On October 28, 2020, the Company entered into a Third Amendment to Revolving Credit Agreement ("Revolving Credit Facility"), amending the Revolving Credit Facility dated as of November 24, 2014 with Truist Bank, successor by merger to SunTrust Bank ("Truist"), which extended the maturity date to October 28, 2023. As described in Note 9 to these Condensed Consolidated Financial Statements, the Revolving Credit Facility was amended by a new revolving credit facility entered into by the Company on October 6, 2023, which replaced the Revolving Credit Facility.

Under the Revolving Credit Facility, the Company was permitted to borrow up to $65.0 million, which included a $5.0 million swingline sub-facility and a $5.0 million letter of credit sub-facility, as well as an accordion feature that allowed the Company to increase the Revolving Credit Facility by a total of up to $25.0 million, subject to securing additional commitments from existing lenders or new lending institutions.

At the Company’s election, the borrowings under the Revolving Credit Facility would bear interest at either (1) a rate per annum equal to the highest of Truist’s prime rate or 0.5% in excess of the Federal Funds Rate or 1.0% in excess of one-month LIBOR (the "Base Rate"), plus an applicable margin, or (2) the one, two, three, or six-month per annum LIBOR for deposits in the applicable currency (the "Eurocurrency Rate"), as selected by the Company, plus an applicable margin. The applicable margin for Eurocurrency Rate loans would depend on the Company’s funded debt leverage ratio and would vary from 1.50% to 1.75%. The applicable margin for Base Rate loans would depend on the Company’s funded debt leverage ratio and would vary from 0.50% to 0.75%. Commitment fees and letter of credit fees were also payable under the Revolving Credit Facility. Principal would be payable in full at maturity on October 28, 2023, and there were no scheduled principal payments prior to maturity. The Company was required to pay a commitment fee ranging between 20 and 30 basis points per annum of the average daily unused portion of the Revolving Credit Facility, depending on the Company’s funded debt leverage ratio. The obligations under the Revolving Credit Facility were guaranteed by each of the Company’s subsidiaries.

The Revolving Credit Facility contained certain covenants that, among other things, restricted additional indebtedness, liens and encumbrances, changes to the character of the Company’s business, acquisitions, asset dispositions, mergers and consolidations, sale or discount of receivables, creation or acquisitions of additional subsidiaries, and other matters customarily restricted in such agreements.

In addition, the Revolving Credit Facility required the Company to meet certain financial tests, including, without limitation:

•	a funded debt leverage ratio (consolidated debt/consolidated EBITDA) of not greater than 3.0 to 1.0; and

•	an interest coverage ratio (consolidated EBITDA/consolidated interest expense) of not less than 3.0 to 1.0.

As of September 30, 2023, the Company was in compliance with all covenants. There were no balances outstanding on the Revolving Credit Facility as of or during the three and nine months ended September 30, 2023.

On February 20, 2023, the Company's Board of Directors ("Board") approved a dividend policy, marking the first quarterly cash dividend policy adopted by the Company ("Dividend Policy"). During the nine months ended September 30, 2023, the Board declared the following quarterly dividends under the Dividend Policy:

Dividend Payment Date	Dividend Declaration Date	Dividend Per Share		Record Date	Cash Outlay
April 28, 2023	February 20, 2023	$	0.025	April 17, 2023	$	767,000

September 29, 2023	July 24, 2023		0.025	September 18, 2023		767,000
Total dividends		$	0.075		$	2,301,000

Additionally, on October 23, 2023, the Board approved the Company’s fourth quarterly cash dividend of $0.025 per share, payable on December 22, 2023 to holders of record on December 11, 2023.

Stock-Based Compensation

The Company has stock awards outstanding under its 2016 Omnibus Incentive Plan and 2022 Omnibus Incentive Plan. The Company accounts for its stock-based compensation plans using the fair-value based method for costs related to share-based payments, including restricted share units (“RSUs”) and stock options. During the nine months ended September 30, 2023, the Company issued 128,942 RSUs subject to service-based time vesting, with a weighted average grant date fair value of $23.61 per share, measured based on the closing fair market value of the Company's stock on the date of the grant. During the nine months ended September 30, 2022, the Company issued 140,473 RSUs subject to service-based time vesting, with a weighted average grant date fair value of $20.31 per share, measured based on the closing fair market value of the Company’s stock on the date of grant.

During the nine months ended September 30, 2023, the Company granted 138,000 performance-based RSUs, the vesting of which occurs over a five-year period and is contingent upon continued service and achieving certain performance criteria established by the Compensation Committee on an annual basis in increments of 15%, 20%, 20%, 20%, and 25% based on performance in 2023, 2024, 2025, 2026, and 2027, respectively. The performance criteria for the first-year tranche, or 20,700 of these performance-based RSUs, is based on 2023 adjusted EBITDA. The measurement date for these 20,700 performance-based RSUs was established during the first quarter of 2023 with a grant date fair value of $26.25 per share, measured based on the closing fair market value of the Company's stock on the date the performance criteria was established. The performance criteria for the remaining 117,300 performance-based RSUs has not yet been determined and will be established on an annual basis in 2024, 2025, 2026, and 2027, as applicable; therefore, the measurement date for these remaining 117,300 performance-based RSUs cannot be determined until the performance criteria have been established.

During the nine months ended September 30, 2022, the Company granted 91,042 performance-based RSUs, the vesting of which occurs over a five-year period and is contingent upon continued service and achieving certain performance criteria established by the Compensation Committee on an annual basis in increments of 15%, 20%, 20%, 20%, and 25% based on performance in 2022, 2023, 2024, 2025, and 2026, respectively. The performance criteria for the second-year tranche, or 18,210 of these performance-based RSUs, is based on 2023 adjusted EBITDA. The measurement date for these 18,210 performance-based RSUs was established during the first quarter of 2023 with a grant date fair value of $26.25 per share, measured based on the closing fair market value of the Company's stock on the date the performance criteria was established. The performance criteria for the remaining 59,178 performance-based RSUs has not yet been determined and will be established on an annual basis in 2024, 2025, and 2026, as applicable; therefore, the measurement date for these remaining 59,178 performance-based RSUs cannot be determined until the performance criteria have been established.

Total stock-based compensation expense recognized in the Condensed Consolidated Statements of Income is as follows (in thousands):

	*Three Months Ended September 30,*				*Nine Months Ended September 30,*
	*2023*		*2022*		*2023*		*2022*

Business Description and Basis of Presentation [Text Block]

1. OVERVIEW AND BASIS OF PRESENTATION

Company Overview

HealthStream primarily provides Software-as-a-Service ("SaaS") based applications for healthcare organizations—all designed to improve business and clinical outcomes by supporting the people who deliver patient care. We are focused on helping healthcare organizations meet their ongoing clinical development, talent management, training, education, assessment, competency management, safety and compliance, scheduling, and provider credentialing, privileging, and enrollment needs. The Company is organized and operated according to our One HealthStream approach, with our hStream technology platform at the center of that approach. Increasingly, SaaS based applications in our diverse ecosystem of solutions utilize our proprietary hStream technology platform to enhance their value proposition by creating interoperability with and among other applications. As used in this Report, “HealthStream,” “Company,” “we,” “us,” and “our” mean HealthStream, Inc. and its subsidiaries, unless the context indicates otherwise.

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (“US GAAP”) for interim financial information and with the instructions to Form 10‑Q and Article 10 of Regulation S‑X. Accordingly, condensed consolidated financial statements do not include all of the information and footnotes required by US GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. All intercompany transactions have been eliminated in consolidation. Operating results for the three and nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023.

The Condensed Consolidated Balance Sheet at December 31, 2022 was derived from the audited Consolidated Financial Statements at that date but does not include all of the information and footnotes required by US GAAP for a complete set of financial statements. For further information, refer to the Consolidated Financial Statements and Notes thereto for the year ended December 31, 2022 (included in the Company's Annual Report on Form 10-K, filed with the Securities and Exchange Commission on February 28, 2023).

Consolidated Segment Information

Our business is managed and organized around a single platform strategy, also referred to as our One HealthStream approach. At the center of this single platform strategy is our hStream technology platform. By facilitating interoperability among our applications, as well as third party applications, we believe that our hStream technology platform is allowing stand-alone applications to leverage each other to more efficiently and effectively empower our customers to manage their business and improve their outcomes.

As indicated in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, filed on February 28, 2023, the Company reached an inflection point in its efforts to operate according to its single platform strategy, One HealthStream. Since January 1, 2023, the Company’s business has been organized and managed around a consolidated, enterprise approach, including with regard to technology, operations, accounting, internal reporting (including the nature of information reviewed by our key decision maker), organization structure, compensation, performance assessment, and resource allocation.

As the result of these developments, the Company determined that Workforce Solutions and Provider Solutions were no longer separate operating segments or separate reportable segments as of January 1, 2023, such that the Company would no longer present two reportable segments for periods beginning on and after this date. As such, since January 1, 2023, the Company has had a single reportable segment, such that the Company is presenting historical financial information on a single segment basis in this Quarterly Report on Form 10-Q for the three and nine months ended September 30, 2023. For purposes of reporting historical 2022 results in this Quarterly Report on Form 10-Q, we are reporting comparable performance on a consolidated basis unless otherwise indicated.

7. BUSINESS COMBINATIONS

On December 31, 2022, the Company acquired substantially all of the assets of Electronic Education Documentation System, LLC (d/b/a eeds) ("eeds"), an Asheville, North Carolina-based healthcare technology company offering a SaaS-based continuing education (CME/CE) management system for healthcare organizations, for approximately $6.6 million in cash, reflecting customary purchase price adjustments made to the purchase price paid of $7.0 million. During the nine months ended September 30, 2023, the Company made adjustments to customer relationships, developed technology, non-compete, and trade name intangibles based on updated information obtained since the preliminary estimates were made. As a result, the Company recorded a measurement period adjustment which increased customer relationships and non-compete intangible assets by $2.0 million and $0.1 million, respectively, while the developed technology and trade name intangible assets were decreased by $0.8 million and $20,000, respectively, resulting in a decrease to goodwill of $1.3 million for the net change in the fair value of identifiable intangible assets.

Earnings Per Share [Text Block]

5. EARNINGS PER SHARE

Basic earnings per share is computed by dividing the net income available to common shareholders for the period by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing the net income available to common shareholders for the period by the weighted average number of potentially dilutive common and common equivalent shares outstanding during the period. Common equivalent shares are composed of incremental common shares issuable upon the exercise of stock options and RSUs subject to vesting. The dilutive effect of common equivalent shares is included in diluted earnings per share by application of the treasury stock method. The total number of common equivalent shares excluded from the calculations of diluted earnings per share, due to their anti-dilutive effect or contingent performance conditions, was approximately 340,000 and 205,000 for the three months ended September 30, 2023 and 2022, respectively, and 278,000 and 217,000 for the nine months ended September 30, 2023 and 2022, respectively.

The following table sets forth the computation of basic and diluted earnings per share (in thousands, except per share data):

Revenue from Contract with Customer [Text Block]

2. REVENUE RECOGNITION AND SALES COMMISSIONS

Revenue Recognition

Revenues are recognized when control of the promised goods or services is transferred to the customer in an amount that reflects the consideration the Company expects to be entitled in exchange for transferring those goods or services. Revenue is recognized based on the following five step model:

•

Identification of the contract with a customer

•

Identification of the performance obligations in the contract

•

Determination of the transaction price

•

Allocation of the transaction price to the performance obligations in the contract

•

Recognition of revenue when, or as, the Company satisfies a performance obligation

The following table represents revenues disaggregated by revenue source (in thousands). Sales taxes are excluded from revenues.

	*Three Months Ended September 30,*				*Nine Months Ended September 30,*
	*2023*		*2022*		*2023*		*2022*
Subscription services	$	67,473	$	64,067	$	199,993	$	188,613
Professional services		2,866		3,218		8,489		9,677
Total revenues, net	$	70,339	$	67,285	$	208,482	$	198,290

For the three months ended September 30, 2023 and 2022, the Company recognized a charge of $0.3 million and a reduction of $44,000 in impairment losses on receivables and contract assets arising from the Company's contracts with customers, respectively. For the nine months ended September 30, 2023 and 2022, the Company recognized $0.7 million and $0.4 million in impairment losses on receivables and contract assets arising from the Company’s contracts with customers.

Deferred revenue represents contract liabilities that are recorded when cash payments are received or are due in advance of our satisfaction of performance obligations. During the three months ended September 30, 2023 and 2022, we recognized revenues of approximately $42.2 million and $39.9 million, respectively, from amounts included in deferred revenue at the beginning of the respective periods. During the nine months ended September 30, 2023 and 2022, we recognized revenues of approximately $76.0 million and $67.9 million, respectively, from amounts included in deferred revenue at the beginning of the respective periods. As of September 30, 2023, approximately $511 million of revenue is expected to be recognized from remaining performance obligations under contracts with customers. We expect to recognize revenue related to approximately 44% of these remaining performance obligations over the next 12 months, with the remaining amounts recognized thereafter.

Sales Commissions

Sales commissions earned by our sales force are considered incremental and recoverable costs of obtaining a contract with a customer. The Company recorded amortization of deferred commissions of approximately $3.0 million and $2.8 million for the three months ended September 30, 2023 and 2022, and $8.5 million and $7.8 million for the nine months ended September 30, 2023 and 2022, respectively, which is included in sales and marketing expenses in the accompanying Condensed Consolidated Statements of Income.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

3. INCOME TAXES

Income taxes are accounted for using the asset and liability method, whereby deferred tax assets and liabilities are determined based on the temporary differences between the financial statement and tax bases of assets and liabilities measured at tax rates that will be in effect for the year in which the differences are expected to affect taxable income.

The Company computes its interim period provision for income taxes by applying the estimated annual effective tax rate to year-to-date pretax income or loss and adjusts the provision for discrete tax items recorded in the period. During the three months ended September 30, 2023 and 2022, the Company recorded a provision for income taxes of approximately $1.6 million and $1.3 million, respectively. During the nine months ended September 30, 2023 and 2022, the Company recorded a provision for income taxes of $2.5 million and $2.7 million, respectively.

The Company’s effective tax rate was 19% and 22% for the nine months ended September 30, 2023 and 2022, respectively. The Company’s effective tax rate primarily reflects the statutory corporate income tax rate, the net effect of state taxes, foreign income taxes, and the effect of various permanent tax differences. The Company recognizes excess tax benefits and tax deficiencies associated with stock-based awards as a component of its provision for income taxes. During the nine months ended September 30, 2023, the Company recorded discrete tax benefits of $0.1 million, which consisted primarily of tax benefits associated with changes in state apportionment rules in Tennessee upon the enactment of the Tennessee Works Tax Act, in the amount of $0.6 million and stock-based awards in the amount of $0.1 million, partially offset by $0.3 million of discrete tax expense related to reserves for uncertain tax positions and $0.3 million of discrete tax expense associated with the Company merging VerityStream, Inc. ("VerityStream") into HealthStream. During the nine months ended September 30, 2022, the Company recorded discrete tax benefits of $16,000, which consisted primarily of a $0.3 million tax benefit associated with a nontaxable gain of $0.9 million recognized from the change in fair value of our previously held minority interest in CloudCME, LLC ("CloudCME") as well as a $0.1 million tax benefit for changes in estimated tax credits. This tax benefit was partially offset by $0.3 million of tax expense related to uncertain tax positions and $0.1 million of excess tax deficiencies associated with stock-based awards.

9. SUBSEQUENT EVENT

On October 6, 2023, the Company entered into an Amended and Restated Revolving Credit Agreement ("New Revolving Credit Facility"), amending the Revolving Credit Facility dated as of November 24, 2014, as amended, with certain lenders party thereto from time to time, and Truist, as Administrative Agent for the lenders. Under the New Revolving Credit Facility, the Company may borrow up to $50.0 million, which includes a $5.0 million swingline sub-facility and a $5.0 million letter of credit sub-facility, as well as an accordion feature that allows the Company to increase the Revolving Credit Facility by a total of up to $25.0 million, subject to securing additional commitments from existing lenders or new lending institutions. The New Revolving Credit Facility has a maturity date of October 6, 2026.

The Company's obligations under the New Revolving Credit Facility are unsecured. In addition, if the Company forms or acquires any domestic subsidiaries, the loans and other obligations under the New Revolving Credit Facility will be guaranteed by such domestic subsidiaries.

At the Company’s election, the borrowings under the New Revolving Credit Facility, other than the swingline loans, bear interest at either (1) a base rate defined as the highest of (a) the rate which the Administrative Agent announces from time to time as its prime lending rate, as in effect from time to time, or (b) the Federal Funds Rate, as in effect from time to time, plus one-half of one percent (0.50%) per annum (any changes in such rates to be effective as of the date of any change in such rate), plus in each case an applicable margin that varies with the company’s funded debt leverage ratio; or (2) a term secured overnight financing rate (“SOFR”) defined as the greater of (a)(i) the forward-looking term rate based on SOFR determined as of the reference time for such interest period with a term equivalent to such interest period plus (ii) a term SOFR adjustment equal to 0.10% per annum and (b) zero, plus, in each case, an applicable margin that varies with the Company’s consolidated total leverage ratio. The Company’s borrowings under the swingline loans bear interest at the base rate plus the applicable margin. The initial applicable margin for base rate loans is 0.50% and the initial applicable margin SOFR loans is 1.50%. The applicable margins will be adjusted quarterly, in each case two (2) business days after the Administrative Agent's receipt of the Company's quarterly financial statements. The Company is also required to pay a commitment fee accruing on the unused revolving commitment, which fee initially is 20 basis points per annum and a letter of credit fee, accruing at a rate per annum equal to the applicable margin for SOFR loans then in effect on the daily average amount of such lender’s letter of credit exposure.

Principal is payable in full at maturity on October 6, 2026, and there are no scheduled principal payments prior to maturity. Interest on base rate loans and swingline loans is payable quarterly in arrears, and interest on SOFR loans is payable at the end of each interest period, and in the case of interest periods longer than three months, on each day which occurs every three months after the initial date of such interest period.

In addition, the New Revolving Credit Facility requires the Company to meet certain financial tests, including, without limitation:

•	a funded debt leverage ratio of not greater than 3.0 to 1.0; and

•	an interest coverage ratio of not less than 3.0 to 1.0.

In addition, the New Revolving Credit Facility contains certain customary affirmative and negative covenants that, among other things, restrict additional indebtedness, liens and encumbrances, changes to the character of the Company’s business, acquisitions, asset dispositions, mergers and consolidations, sale or discount of receivables, creation or acquisitions of additional subsidiaries, and other matters customarily restricted in such agreements.
