HEALTHSTREAM INC

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business

HealthStream, Inc. (the "Company") was incorporated in1990 as a Tennessee corporation and is headquartered in Nashville, Tennessee. The Company 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. The Company is 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 its One HealthStream approach, with its hStream technology platform at the center of that approach. Increasingly, SaaS-based applications in its diverse ecosystem of solutions utilize its proprietary hStream technology platform to enhance their value proposition by creating interoperability with and among other applications.

Recognition of Revenue

In accordance with Accounting Standards Codification ("ASC")606, Revenue from Contracts with Customers, the Company's 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 followingfive step model:

Subscription revenues primarily consist of fees in consideration of providing customers access toone or more of its SaaS-based solutions and/or courseware subscriptions, as well as fees related to licensing agreements, all of which include routine customer support and technology enhancements. Revenue is generally recognized over time during the contract term beginning when the service is made available to the customer. Subscription contracts are generally non-cancelable,one tofive years in length, and billed annually, semi-annually, quarterly, or monthly in advance.

Professional services revenues primarily consist of fees for implementation and onboarding services, consulting, and training. The majority of professional services contracts are billed in advance based on a fixed price basis, and revenue is recognized over time as the services are performed. For both subscription services and professional services, the time between billing the customer and when performance obligations are satisfied is generallynot significant.

Contracts with customers often contain promises for multiple goods and services. For these contracts, the Company accounts for the promised goods and services in its contracts as separate performance obligations if they are distinct. The contract price, which represents transaction price when the contract reflects a fixed fee arrangement, or management’s estimate of variable consideration including application of the constraint when the contract doesnot have a fixed fee, is allocated to the separate performance obligations on a relative standalone selling price basis. The Company generally determines standalone selling prices based on the standard list price for each product, taking into consideration certain factors, including contract length and the number of subscriptions within the contract.

The Company receives payments from customers based on billing schedules established in its contracts. Accounts receivable - unbilled represent contract assets related to its conditional right to consideration for subscription and professional services contracts where performance has occurred under the contract. Accounts receivable are primarily comprised of trade receivables that are recorded at the invoice amount, net of an allowance for credit losses, when the right to consideration becomes unconditional.

Deferred revenue represents contract liabilities that are recorded when cash payments are received or are due in advance of satisfaction of performance obligations.

Basis of Presentation

The Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Business Segments

The Company’s chief operating decision maker ("CODM") is its Chief Executive Officer. 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 the CODM), organization structure, compensation, performance assessment, and resource allocation. The Company’s CODM uses consolidated financial information to make operating decisions, assess financial performance, and allocate resources. Discrete financial information to measure profitability isnot prepared at any other level. Taking these factors into account, since* January 1, 2023**,* the Company has a single reportable segment, such that the Company has presented historical financial information and comparable performance on a single segment basis in this Annual Report on Form10-K for the year ended* December 31, 2023**.*

Use of Estimates

The Consolidated Financial Statements are prepared in accordance with United States generally accepted accounting principles. These accounting principles require management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates and such differences could be material to the Consolidated Financial Statements.

Cash Equivalents

The Company considers cash equivalents to be unrestricted, highly liquid investments with initial maturities of less thanthree months.

Marketable Securities

Marketable securities are classified as available for sale and are stated at fair market value, with the unrealized gains and losses, net of tax, reported in other accumulated comprehensive income (loss) on the accompanying Consolidated Balance Sheets. Realized gains and losses and declines in market value due to credit-related factors on investments in marketable securities are included in other income, net on the accompanying Consolidated Statements of Income. The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as available for sale are included in other income, net on the accompanying Consolidated Statements of Income. Premiums and discounts are amortized over the life of the related available for sale security as an adjustment to the yield using the effective interest method.

Deferred Commissions

Deferred commissions represent incremental costs to acquire contracts with customers, such as the sales commission payment and associated payroll taxes, which are capitalized and amortized consistent with the transfer of the goods or services to the customer over the expected period of benefit. Capitalized contract costs are included under the caption deferred commissions in the accompanying Consolidated Balance Sheets. The expected period of benefit is the contract term, except when the capitalized commission is expected to provide economic benefit to the Company for a period longer than the contract term, such as for new customer or incremental sales where renewals are expected and renewal commissions arenot commensurate with initial commissions. Non-commensurate commissions are amortized over the greater of the contract term or technological obsolescence period ofthree years.

Prepaid Royalties

Prepaid royalties represent advance payments to business partners under revenue sharing arrangements for which the Company sells and delivers such partner products to its customers. Royalties are typically paid in advance at the commencement of the subscription period or periodically throughout the subscription period, such as in quarterly, bi-annual, or annual installments. Royalty payments are amortized over the term of the underlying subscription contracts, which generally range fromone tofive years, in order to match the direct royalty costs to the same period the subscription revenue is recognized. Amortization of prepaid royalties is included under the caption cost of revenues (excluding depreciation and amortization) in the accompanying Consolidated Statements of Income.

47

Allowance for Credit Losses

The Company estimates its allowance for credit losses based on its historical collection experience, a review in each period of the aging status of the then-outstanding accounts receivable, and external market factors. Uncollectible receivables are written-off in the period management believes it has exhausted its ability to collect payment from the customer. Expected credit losses are recorded under the caption other general and administrative expenses in the accompanying Consolidated Statements of Income.

Changes in the allowance for credit losses and the amounts charged to bad debt expense for thethree years ended* December**31,* 2023 were as follows (in thousands):

Capitalized Software and Content Development

Capitalized software and content development is stated on the basis of cost and is presented net of accumulated amortization. The Company capitalizes costs incurred during the development phase for projects to develop software and content. These assets are generally amortized using the straight-line method over three years. The Company capitalized $25.5 million and $23.8 million during2023 and2022, respectively. Amortization of capitalized software development was $22.0 million, $18.9 million, and $15.6 million during2023,2022, and2021, respectively. Maintenance and operating costs are expensed as incurred. As of* December 31, 2023and2022*, there wereno capitalized software development costs for external computer software developed for resale.

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants at the measurement date. The fair value hierarchy prioritizes the inputs to valuation techniques used in measuring fair value. There arethree levels to the fair value hierarchy based on the reliability of inputs, as follows:

Level1 – Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 – Inputs other than quoted prices included in Level1 that are observable for the asset or liability, either directly or indirectly.

Level 3 – Unobservable inputs in which little orno market data exists, therefore requiring the Company to develop its own assumptions.

The Company evaluates assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level at which to classify them for each reporting period. This determination* mayrequire significant judgments to be made by the Company. At December 31, 2023and2022*, the Company's assets measured at fair value on a recurring basis consisted of marketable securities, which are classified as available for sale (see Note4 – Marketable Securities).

Property and Equipment

Property and equipment are stated on the basis of cost. Depreciation is provided on the straight-line method over the following estimated useful lives, except for leasehold improvements, which are amortized over the shorter of the estimated useful life or their respective lease term.

Goodwill

Goodwill represents the excess of purchase price in a business combination over the fair value of the net identifiable assets acquired, including intangible assets. The carrying amount of its goodwill is evaluated for impairment at least annually during thefourth quarter and whenever events or changes in facts or circumstances indicate that impairment* mayexist. In accordance with ASC350,* Intangibles–* Goodwill and Other*, companies* mayopt tofirst* assess qualitative factors to determine whether it is more likely thannot that the fair value of a reporting unit is less than its carrying amount. A qualitative assessment includes factors such as financial performance, industry and market metrics, and other factors affecting the reporting unit. If this assessment concludes that it is more likely thannot that the fair value of a reporting unit exceeds its carrying value, then goodwill isnot considered impaired andno further impairment testing is required. Conversely, if the qualitative assessment concludes that it is more likely thannot that the fair value of a reporting unit is less than its carrying value, the Company must then compare the fair value of the reporting unit to its carrying value. The Company determines fair value of the reporting unit using both income and market-based models. These models require the use of various assumptions relating to cash flow projections, growth rates, discount rates, and terminal value calculations. There wereno goodwill impairments identified or recorded for the years ended* December 31, 2023*,2022, or2021.

48

Intangible Assets

The Company estimates fair values of intangible assets using the income and cost methods, which are based on management’s estimates and assumptions. As of* December 31, 2023*, intangible assets include customer relationships, internally developed technologies, non-competition agreements, and trade names. Intangible assets that are considered to have definite useful lives are being amortized on a straight-line basis over periods ranging betweentwo andeighteen years. The weighted average amortization period for definite lived intangible assets as of* December 31, 2023* was 11.7 years. Intangible assets considered to have indefinite useful lives are evaluated for impairment at least annually during thefourth quarter, and all intangible assets are reviewed for impairment whenever events or changes in facts or circumstances indicate that the carrying amount of the assets* may**not* be recoverable. There wereno intangible asset impairments identified or recorded for the years ended* December 31, 2023*,2022, or2021.

Long-Lived Assets

Long-lived assets to be held for use are reviewed for events or changes in facts and circumstances, both internally and externally, which* mayindicate that an impairment of long-lived assets held for use is present. Purchases of long-lived assets (including capitalized software and content development costs) totaled $27.3 million, $25.9 million, and $23.4 million for the years ended December 31, 2023,2022, and2021, respectively. The Company measures any impairment using observable market values or discounted future cash flows from the related long-lived assets. The cash flow estimates and discount rates incorporate management’s best estimates, using appropriate and customary assumptions and projections at the date of evaluation. Management periodically evaluates whether the carrying value of long-lived assets, including intangible assets, property and equipment, capitalized software development, deferred commissions, and other assets will be recoverable. There wereno long-lived asset impairments identified or recorded for the years ended December 31, 2023*,2022, or2021.

Non-Marketable Equity Investments

Non-marketable equity investments in limited liability companies with specific ownership accounts for each investornot resulting in a controlling financial interest are accounted for using the equity method of accounting. Non-marketable equity investments of preferred stock in corporations that donot result in a controlling financial interest are accounted for using the measurement alternative for equity investments that donot have readily determinable fair values. Accounting Standards Update ("ASU")2016-01, Financial Instruments–* Overall (Subtopic825-10)* requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. The fair value of non-marketable equity investments isnot estimated if there areno identified events or changes in circumstances that* may*have a significant adverse effect on the fair value of the investment. The proportionate share of income or loss from equity method investments and any changes in fair value of investments accounted for using the measurement alternative are recorded under the caption other income, net in the accompanying Consolidated Statements of Income.

Financial Instruments

The Company has various financial instruments, including cash and cash equivalents, accounts receivable, accounts receivable-unbilled, accounts payable, and accrued liabilities. The carrying amounts of these financial instruments approximate fair value because of the short-term maturity or short-term nature of such instruments. The Company also has marketable securities, which are recorded at approximate fair value based on quoted market prices or alternative pricing sources (see Note4 – Marketable Securities) and non-marketable equity investments, which are recorded under the equity method or under the measurement alternative (see Note15 - Non-Marketable Equity Investments).

Advertising

The Company expenses the costs of advertising as incurred. Advertising expense for the years ended* December 31, 2023*,2022, and2021 was $1.5 million, $1.9 million, and $1.9 million, respectively, and is included under the caption sales and marketing expense in the accompanying Consolidated Statements of Income.

Shipping and Handling Costs

Shipping and handling costs that are associated with delivering products and services are included under the caption cost of revenues (excluding depreciation and amortization) in the accompanying Consolidated Statements of Income.

49

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. Management evaluates all available evidence, both positive and negative, to determine whether, based on the weight of that evidence, a valuation allowance is needed. Future realization of the tax benefit of an existing deductible temporary difference or carryforward ultimately depends on the existence of sufficient taxable income of the appropriate character within the carryback or carryforward period available under the tax law. There arefour possible sources of taxable income that* maybe available under the tax law to realize a tax benefit for deductible temporary differences and carryforwards:1) future reversals of existing taxable temporary differences,2) future taxable income exclusive of reversing temporary differences and carryforwards,3) taxable income in prior carryback year(s) if carryback is permitted under the tax law, and4*) tax-planning strategies that would, if necessary, be implemented to realize deductible temporary differences or carryforwards prior to their expiration. Management reviews the realizability of its deferred tax assets each reporting period to identify whether any significant changes in circumstances or assumptions have occurred that could materially affect the realizability of deferred tax assets. As of* December 31, 2023*, the Company had established a valuation allowance of $2.0 million for the portion of its net deferred tax assets that arenot more likely thannot expected to be realized. The Company accounts for income tax uncertainties using a more-likely-than-not recognition threshold based on the technical merits of the tax position taken. Tax positions that meet the more-likely-than-not recognition threshold are measured in order to determine the tax benefit to be recognized in the financial statements.

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 for the period by the weighted average number of 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 restricted share units subject to vesting. The dilutive effect of common equivalent shares is included in diluted earnings per share by application of the treasury stock method. Common equivalent shares that have an anti-dilutive effect on diluted net income per share are excluded from the calculation of diluted weighted average shares outstanding.

Concentrations of Credit Risk and Significant Customers

The Company’s credit risks relate primarily to cash and cash equivalents, marketable securities, and accounts receivable. The Company places its temporary excess cash in high quality, short-term money market instruments. At times, such investments* may*be in excess of the FDIC insurance limits. Marketable securities consist primarily of U.S. treasuries.

The Company sells its products and services to various companies in the healthcare industry that are primarily located in the United States. Customer credit worthiness evaluations are performed on an as-needed basis, and the Company generally requiresno collateral from customers. An allowance for credit losses is maintained for potentially uncollectible accounts receivable. The Company didnot have any single customer representing over10% of net revenues or accounts receivable during or as of the years ended* December 31, 2023*,2022, or2021, respectively.

Stock-Based Compensation

As of* December 31, 2023*, the Company maintainedtwo stock-based compensation plans under which awards are outstanding, as described in Note10. The Company accounts for stock-based compensation using the fair-value based method for costs related to share-based payments, including stock options and restricted share units. The Company uses the Black Scholes option pricing model for calculating the fair value of option awards issued under its stock-based compensation plans. The Company measures compensation cost of restricted share units based on the closing fair market value of the Company’s stock on the date of grant. Stock-based compensation cost is measured at the grant date, based on the fair value of the award that is ultimately expected to vest, and is recognized as an expense over the requisite service period. The Company recognizes tax benefits or deficiencies from stock-based compensation if an excess tax benefit or deficiency is realized. Excess tax benefits and deficiencies are reflected in the Consolidated Statements of Income as a component of the provision for income taxes when realized.

Leases

The Company has several non-cancelable agreements to lease office space. For leases with a lease term greater than12 months, the Company recognizes a right-of-use ("ROU") asset and a lease liability on the balance sheet at the lease commencement date. Lease liabilities and their corresponding ROU assets are recorded based on the present value of the future lease payments over the expected lease term.

The Company doesnot have any lease contracts that contain: (1) an option to extend that the Company is reasonably certain to exercise, (2) an option to terminate that the Company is reasonably certainnot to exercise, or (3) an option to extend (ornot to terminate) in which exercise of the option is controlled by the lessor. Additionally, the Company doesnot have any leases with residual value guarantees or material restrictive covenants. Most of the Company’s lease agreements contain provisions for escalating rent payments over the terms of the leases, which escalations are either fixed within the contract or are variable based on the consumer price index.

The Company’s leases donot contain readily determinable implicit discount rates, and as such the Company must use its incremental borrowing rate to discount the future lease payments based on information available at lease commencement. The incremental borrowing rate was estimated by determining the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment.

50

Foreign Currency

The functional currency for the Company’s subsidiaries is determined based on the primary economic environment in which the subsidiary operates. The Company translates the assets and liabilities of its non-U.S. dollar functional currency subsidiaries into U.S. dollars using exchange rates in effect at the end of each period. Revenues and expenses for these subsidiaries are translated using rates that approximate those in effect during the period. Gains and losses from these translations are recognized as cumulative translation adjustments included in accumulated other comprehensive income in the Consolidated Balance Sheets.

Recently Issued Accounting Pronouncements Not Yet Adopted

In* November 2023,the Financial Accounting Standards Board ("FASB") issued ASU2023*-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The new guidance requires disclosures of significant reportable segment expenses that are regularly provided to the CODM and other segment items on an interim and annual basis. Entities with a single reportable segment will also be required to apply the disclosure requirements in ASU2023-07 on an interim and annual basis. The ASU will be effective for annual periods beginning after* December 15, 2023,and interim periods within fiscal years beginning after December 15, 2024.Early adoption of the ASU is permitted and should be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the impact of adopting ASU2023*-07 and expects to adopt this ASU for the year ending* December 31, 2024.*

In* December 2023,the FASB issued ASU2023*-09, Income Taxes (Topic740*): Improvements to Income Tax Disclosures*, which requires public entities to provide disclosure of disaggregated information in the entity’s tax rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. The ASU is effective for fiscal years beginning after* December 15, 2024,*with early adoption permitted. The Company is currently evaluating the impact of adopting this ASU.

5. 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.

The following table represents revenues disaggregated by revenue source for thethree years ended* December 31, 2023*,2022, and2021 (in thousands). Sales taxes are excluded from revenues.

A reconciliation of income taxes at the statutory federal income tax rate to the provision for income taxes included in the accompanying Consolidated Statements of Income is as follows (in thousands):

Management periodically assesses the realizability of its deferred tax assets, and to the extent that a recovery isnot likely, a valuation allowance is established to reduce the deferred tax asset to the amount estimated to be recoverable. At* December 31, 2023*, the Company has a valuation allowance of $2.0 million recorded against deferred tax assets for state net operating losses and certain foreign deferred tax assets.

As of* December 31, 2023*, the Company had federal, state, and foreign net operating loss carryforwards of $3.3 million, $9.0 million, and $8.4 million, respectively. Certain losses have an indefinite carryforward period, while other loss carryforwards will expire in years2030 through2043. A portion of the net operating loss carryforwards are subject to annual limitations under Internal Revenue Code Section382.
