Business	1. Business Waystar Holding Corp. (“Waystar”, “we” or “our”) is a provider of mission-critical cloud technology to healthcare organizations. Our enterprise-grade platform transforms the complex and disparate processes comprising healthcare payments received by healthcare providers from payers and patients, from pre-service engagement through post-service remittance and reconciliation. Our platform enhances data integrity, eliminates manual tasks, and improves claim and billing accuracy, which results in better transparency, reduced labor costs, and faster, more accurate reimbursement and cash flow. The market for our solutions extends throughout the United States and includes Puerto Rico and other U.S. Territories. Risks and Uncertainties— On occasion, we enter into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, we indemnify, hold harmless, and agree to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, in connection with any trade secret, copyright, patent, or other intellectual property infringement claim by any third-party with respect to its technology. The terms of these indemnification agreements are generally perpetual any time after the execution of the agreement. The maximum potential future payments we could be required to make under these agreements is not determinable because it involves claims that may be made against us in the future but have not yet been made. Historically, we have not incurred costs to defend lawsuits or settle claims related to these indemnification agreements. We have entered into agreements with our directors or officers that may require us to indemnify them against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from their willful misconduct. No liability associated with such indemnifications was recorded as of June 30, 2024 and December 31, 2023. Reverse Stock Split On May 15, 2024, we effected a 0.605-for-1 reverse stock split of our common stock and a 0.605-for-1 reverse stock split of our Class A common stock. The reverse stock split did not result in an adjustment to the par value of common stock or Class A common stock. The reverse stock split was originally made effective on May 15, 2024 with a 0.62-for-1 ratio and this was retroactively amended on May 22, 2024 which updated the ratio to 0.605-for-1. All references in the accompanying condensed consolidated financial statements and related Note 13, Note 15, and Note 17 have been updated to reflect the effects of the reverse stock split at the amended 0.605-for-1 ratio. The number of shares of common stock, Class A common stock, additional paid-in-capital, options to purchase common stock, and loss per share amounts, which are presented and disclosed in the financial statements and aforementioned footnotes, have been restated on a retroactive basis for all periods presented to reflect the effects of this action. Initial Public Offering In June 2024, we completed our initial public offering (“IPO”) in which we issued and sold 45,000,000 shares of our common stock at $21.50 per share. We received total proceeds of $914.3 million after deducting the underwriters’ discounts and commissions of $53.2 million. Deferred offering costs, which consist of direct incremental legal, accounting and other third-party fees that are directly related to the IPO, were capitalized and offset against proceeds upon the consummation of the IPO. Through the date of the IPO, we had capitalized $8.8 million of deferred offering costs, of which $1.4 million were unpaid as of June 30, 2024. These costs were offset against proceeds upon the consummation of the IPO. As part of the IPO we granted the underwriters the right, for a period of 30 days from the date of the prospectus, to purchase up to 6,750,000 additional shares of common stock from us at the initial public offering price less the underwriting discount. We used the net proceeds from the IPO to repay $909.1 million of outstanding principal indebtedness under our First Lien Credit Facility. See Note 10 below for details.

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Financial Statement Presentation The financial statements include the consolidated balance sheets, statements of operations, statements of comprehensive loss, statements of changes in stockholders’ equity, and statements of cash flows of Waystar and its subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The accompanying unaudited consolidated financial statements and notes have been prepared in accordance with GAAP and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the Company’s financial position, results of operations, changes in stockholders’ equity and cash flows. The results of operations for the six months ended June 30, 2024 are not necessarily indicative of the results for the full year or the results for any future periods. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes for the year ended December 31, 2023 in the prospectus filed with the SEC on June 6, 2024 (the “Prospectus”). We operate as a single business unit. As such, we report our results as a single operating segment that encompasses our entire organization. Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Significant estimates and assumptions are used for, but are not limited to: (1) revenue recognition, including estimated expected customer life; (2) recoverability of accounts receivable and taxes receivable; (3) impairment assessment of goodwill and long-lived intangible assets; (4) fair value of intangibles acquired in business combinations; (5) litigation reserves; (6) depreciation and amortization; (7) fair value of stock options issued to employees and assumed as part of business combinations; (8) fair value of interest rate swaps; and (9) leases, including incremental borrowing rate. Future events and their effects cannot be predicted with certainty, and accordingly, accounting estimates require the exercise of judgment. We evaluate and update assumptions and estimates on an ongoing basis and may employ outside experts to assist in evaluations. Actual results could differ from the estimates used. Revenue Recognition We derive revenue primarily from providing access to our solutions for use in the healthcare industry and in doing so generate two types of revenue: (i) subscription revenue and (ii) volume-based revenue, which account for 99% of total revenue for all periods presented. We also derive revenue from implementation fees for our software, as well as hardware sales to facilitate patient payments. We recognize revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers ● identification of the contract, or contracts, with a client; ● 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; and ● recognition of revenue when, or as, we satisfy a performance obligation Our customers, referred to as clients elsewhere in this report, represent healthcare providers across all types of care settings, including physician practices, clinics, surgical centers, and laboratories, as well as large hospitals and health systems. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. The length of our contracts vary but are typically two three years Revenue from our subscription services as well as from our volume-based services represents a single promise to provide continuous access (i.e., a stand-ready obligation) to our software solutions in the form of a service. Our software products are made available to our clients via a cloud-based, hosted platform where our clients do not have the right or practical ability to take possession of the software. As each day of providing access to the software solutions is substantially the same and the client simultaneously receives and consumes the benefits as services are provided, these services are viewed as a single performance obligation comprised of a series of distinct daily services. Revenue from our subscription services is recognized over time on a ratable basis over the contract term beginning on the date that the service is made available to the client. Volume-based services are priced based on transaction, dollar volume or provider count in a given period. Given the nature of the promise is based on unknown quantities or outcomes of services to be performed over the contract term, the volume-based fee is determined to be variable consideration. The volume-based transaction fees are recognized each day using a time- elapsed output method based on the volume or transaction count at the time the clients’ transactions are processed. Our other services are generally related to implementation activities across all solutions and hardware sales to facilitate patient payments. Implementation services are not considered performance obligations as they do not provide a distinct service to clients without the use of our software solutions. As such, implementation fees related to our solutions are billed upfront and recognized ratably over the contract term. Implementation fees and hardware sales represent less than 1% of total revenue for all periods presented. Our contracts with clients typically include various combinations of our software solutions. Determining whether such software solutions are considered distinct performance obligations that should be accounted for separately versus together requires significant judgment. Specifically, judgment is required to determine whether access to the Company’s SaaS solutions is distinct from other services and solutions included in an arrangement. We follow the requirements of ASC 606-10-55-36 through -40, Revenue from Contracts with Customers, Principal Agent Considerations, in determining the gross versus net revenue presentations for our performance obligations in the contract with a client. Revenue recorded where we act in the capacity of a principal is reported on a gross basis equal to the full amount of consideration to which we expect in exchange for the good or service transferred. Revenue recorded where we act in the capacity of an agent is reported on a net basis, exclusive of any consideration provided to the principal party in the transaction. The principal versus agent evaluation is a matter of judgment that depends on the facts and circumstances of the arrangement and is dependent on whether we control the good or service before it is transferred to the client or whether we are acting as an agent of a third party. This evaluation is performed separately for each performance obligation identified. For the majority of our contracts, we are considered the principal in the transaction with the client and recognize revenue gross of any related channel partner fees or costs. We have certain agency arrangements where third parties control the goods or services provided to a client and we recognize revenue net of any fees owed to these third parties. Payment terms and conditions vary by contract type, although our standard payment terms generally require payment within 30 to 60 days. In instances where the timing of revenue recognition differs from the timing of payment, we have determined our contracts do not generally include a significant financing component. The primary purpose of our invoicing terms is to provide clients with simplified and predictable ways of purchasing our products and services, not to receive financing from our clients or to provide clients with financing. Contract Costs Incremental Costs of Obtaining a Contract Incremental costs of obtaining a contract primarily include commissions paid to our internal sales personnel. We consider all such commissions to be both incremental and recoverable since they are only paid when a contract is secured. These capitalized costs are amortized on a straight-line basis over the expected period of benefit, which is determined based on the average customer life, which includes anticipated renewals of contracts. As of June 30, 2024 and December 31, 2023, the total unamortized costs reported as deferred costs on our balance sheet amounted to $28.3 million and $22.8 million, respectively, for internal sales commissions. For the three months ended June 30, 2024 and 2023, amortization related to the sales commission asset was $2.6 million and $1.8 million, respectively. For the six months ended June 30, 2024 and 2023, amortization related to the sales commission asset was $5.0 million and $3.5 million, respectively. The aforementioned amortization amounts are included in sales and marketing in our consolidated statements of operations. Costs to Fulfill a Contract We capitalize costs incurred to fulfill contracts that i) relate directly to the contract, ii) are expected to generate resources that will be used to satisfy performance obligations under the contract, and iii) are expected to be recovered through revenue generated under the contract. Costs incurred to implement clients on our solutions (e.g., direct labor) are capitalized and amortized on a straight-line basis over the estimated customer life if we expect to recover those costs. As of June 30, 2024 and December 31, 2023, the total unamortized costs reported as deferred costs on our balance sheet amounted to $48.8 million and $43.0 million, respectively, for fulfillment costs. For the three months ended June 30, 2024 and 2023, amortization related to the fulfillment cost asset was $3.0 million and $2.1 million, respectively. For the six months ended June 30, 2024 and 2023, amortization related to the fulfillment cost asset was $5.7 million and $4.0 million, respectively. The aforementioned amortization amounts are included in the costs of revenue in our consolidated statements of operations. There were no impairment losses relating to deferred costs during the periods presented. Channel Partners We account for fees paid to channel partners within sales and marketing expenses in the accompanying statements of operations. For the three months ended June 30, 2024 and 2023, we recorded fees to all channel partners of $16.1 million and $13.0 million, respectively. For the six months ended June 30, 2024 and 2023, we recorded fees to all channel partners of $30.6 million and $25.8 million, respectively. As we are primarily responsible for contracting with and fulfilling contracts for the end user, we record revenue gross of related channel partner fees. Deferred Offering Costs We capitalize within other assets certain legal, accounting and other third-party fees that are directly related to our in-process equity financings, including the planned initial public offering, until such financings are consummated. After consummation of the equity financing, these costs are recorded as a reduction of the proceeds received as a result of the offering. Should a planned equity financing be abandoned, terminated or significantly delayed, the deferred offering costs are immediately written off to operating expenses. Through June 6, 2024, the effective date of our Prospectus, we had capitalized $8.8 million of deferred offering costs, which were charged to shareholders’ equity upon the completion of the IPO (see Note 1). As of December 31, 2023, deferred offering costs capitalized were $5.4 million. Goodwill We account for business combinations under the acquisition method of accounting in accordance with Accounting Standards Codification (“ASC”) 805, Business Combinations, where the total purchase price is allocated to the tangible and identified intangible assets acquired and liabilities assumed based on their estimated fair values. The purchase price is allocated using the information currently available, and may be adjusted, up to one year from acquisition date, after obtaining more information regarding, among other things, asset valuations, liabilities assumed and revisions to preliminary estimates. The purchase price in excess of the fair value of the tangible and identified intangible assets acquired less liabilities assumed is recognized as goodwill. We account for goodwill under the provisions of ASC 350, Intangibles—Goodwill and Other. Goodwill is evaluated for impairment annually on October 1st or whenever there is an impairment indicator. There was no impairment to goodwill during the six months ended June 30, 2024 and 2023, respectively. Refer to Note 6 for more information on goodwill. Debt Issuance Costs Debt issuance costs, net of amortization, are reflected on our balance sheet as a direct reduction in the carrying amount of our long-term debt. In addition, debt issuance costs, net of amortization, related to our revolver debt are included in other assets. Debt issuance costs include fees paid to creditors and third party fees incurred for the issuance of new debt. Debt issuance costs are amortized over the respective term of the debt instruments using the effective interest method, and amortization charges are included in interest expense. Recently Issued Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, “Segment Reporting-Improvements to Reportable Segment Disclosures.” The standard is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. For public business entities, the ASU will be effective for annual periods beginning after December 15, 2023. The guidance will be applied retrospectively unless it is impracticable to do so. Early adoption is permitted. We are currently evaluating the effect of the adoption of this amendment on our consolidated and condensed consolidated financial statements. In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, “Improvements to Income Tax Disclosures”, which requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. For public business entities, the ASU will be effective for annual periods beginning after December 15, 2024. The guidance will be applied on a prospective basis with the option to apply the standard retrospectively. Early adoption is permitted. We are currently evaluating the effect of the adoption of this amendment on our consolidated and condensed consolidated financial statements.

Our payment terms with the client generally comprise an initial payment for implementation services, which includes client enrollment and the setup of contracted solutions on our platform. These implementation fees are due upon contract execution. Additionally, subscription fees are earned on an ongoing basis, which are invoiced monthly. Client payments received in advance of fulfilling the corresponding performance obligations are recorded as contract liabilities. Implementation fees are recognized over the customer life, with any unrecognized amounts deferred as contract liabilities. These amounts are reported as deferred revenue on our consolidated balance sheet.

The transaction price allocated to performance obligations that are unsatisfied (or partially unsatisfied) for executed contracts does not include revenue related to performance obligations that are part of a contract with an original expected duration of one year or less. Additionally, the balance does not include variable consideration that is allocated entirely to wholly unsatisfied promises that form part of a single performance obligation comprised of a series of distinct daily services. Remaining performance obligation estimates are subject to change and are affected by several factors, including terminations and changes in the timing and scope of contracts, arising from contract modifications.

The future cash flows are derived based on the terms of our interest rate swaps, as well as considering published discount factors, and projected SOFR. The fair value of long-term debt was determined using the present value of future cash flows based on the borrowing rates currently available for debt with similar terms and maturities. The carrying value of our first lien term loan facility was $1,290.9 million and $1,730.8 million compared to a fair value of $1,290.9 million and $1,735.1 million at June 30, 2024 and December 31, 2023, respectively. As of June 30, 2024, there is no balance for our second lien term loan facility given the paydown outlined below in Note 10. The carrying value of our second lien term loan facility approximated fair value at December 31, 2023. There were no transfers in or out of Level 3 during the periods presented. ​ As of June 30, 2024 and December 31, 2023, the carrying value of cash equivalents, accounts receivable, accounts payable, accrued liabilities, and other current assets and liabilities approximates fair value due to the short maturities of these instruments. Swaps are Level 2 instruments whose fair value is derived from discounted cash flows adjusted for nonperformance risk.

Pursuant to the Receivables Facility, we sell and/or contribute current and future receivables to Waystar RC, LLC as the Special Purpose Entity (“SPE”). The SPE, in turn, pledges its interests in the receivables to the counterparty, which either makes loans or issues letters of credit on behalf of the SPE. All receivables remain on our balance sheet as they continue to be the property of our consolidated entities under the securitization. The interest rate under the Receivables Facility is 2.36% per annum above the SOFR rate with a minimum base of 0%. The SOFR is adjusted each thirty-day period to the thirty-day SOFR rate. Interest under the Receivables Facility is paid monthly in arrears. At June 30, 2024, the effective interest rate for the Receivables Facility is 7.70%. All principal under the Receivables Facility is due on October 31, 2026. The Receivables Facility contains certain covenants which, among other things, require we maintain certain collection thresholds with respect to our accounts receivable. We were in compliance with all such debt covenants during the periods presented.

We utilized proceeds from the amended First Lien Credit Facility to paydown the remaining principal and interest on the Second Lien Credit Facility (“February 2024 Second Lien Paydown”). In connection with the closing of the IPO in June 2024 (See Note 1), we repaid $909.1 million outstanding principal and $2.8 million accrued interest on our First Lien Credit Facility. Subsequent to this paydown, the remaining principal outstanding on the First Lien Credit Facility is $1.29 billion (“June 2024 First Lien Paydown”). Additionally on June 27, 2024, we entered into the Ninth Amendment to the First Lien Credit Agreement whereby the outstanding balance was repriced bearing an interest rate of 2.75% per annum above the SOFR rate Debt instruments consist primarily of term notes, revolving lines of credit, and a Receivables Facility as follows (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ June 30, December 31, ​ ​ 2024 ​ 2023 First lien term loan facility outstanding debt ​ $ 1,290,900 ​ $ 1,730,816 Second lien term loan facility outstanding debt ​ — ​ 448,000 Receivables facility outstanding debt ​ 70,000 ​ 70,000 Total outstanding debt ​ 1,360,900 ​ 2,248,816 Unamortized debt issuance costs ​ (13,901) ​ (31,155) Current portion of long-term debt ​ (12,909) ​ (17,983) Total long-term debt, net ​ $ 1,334,090 ​ $ 2,199,678 ​ The maturity of long-term principal payments (excluding debt discount) at June 30, 2024 is as follows (in thousands): ​ ​ ​ ​ 2024 $ 6,455 2025 ​ 12,909 2026 ​ 82,909 2027 ​ 12,909 2028 ​ 12,909 Thereafter ​ 1,232,809 ​ ​ $ 1,360,900 ​ As of June 30, 2024 and December 31, 2023, there is no outstanding balance on our revolving credit facility. The interest rate under the revolving credit facility is 3.00% per annum above the SOFR rate with a minimum base of 0.00%. The SOFR is adjusted each thirty-day period to the thirty-day SOFR rate. At June 30, 2024, the effective interest rate for the revolving credit facility is 8.34%. The interest rate under the amended First Lien Credit Facility is 2.75% per annum above the SOFR rate with a minimum base of 0.00%.

As of June 30, 2024, there are 21 payments remaining. The First Lien Credit Agreement contains certain covenants which, among other things, restrict our ability to incur additional indebtedness. We were in compliance with such debt covenants as of June 30, 2024. In connection with the February 2024 First Lien Refinancing, we capitalized creditor fees of $2.8 million and $1.4 million of third-party fees in connection with the issuance of new debt. Additionally, we recorded $10.3 million in third party fees that were expensed immediately, which were recorded in general and administrative expense in our condensed consolidated statements of operations.

Derivative Financial Instruments	11. Derivative Financial Instruments To mitigate the risk of a rise in interest rates on the First Lien Credit Facility, we entered into two interest rate swaps on October 13, 2021 and January 13, 2023. We attempt to minimize our interest risk exposure by fixing our rate through the utilization of interest rate swaps, which are derivative instruments. The interest rate swaps mitigate the exposure on the variable component of interest on our First Lien Credit Facility. Our swaps are entered into with financial institutions that participate in the First Lien Credit Facility. By using a derivative instrument to hedge exposures to changes in interest rates, we expose ourselves to credit risk due to the possible failure of the counterparty to perform under the terms of the derivative contract. As of June 30, 2024 and December 31, 2023, we have the following interest rate swap agreements designated as a hedging instruments: ​ ​ ​ ​ ​ ​ ​ Effective Dates Floating Rate Debt Fixed Rates October 29, 2021 through October 31, 2024 ​ $ 604.1 million 0.67 % January 31, 2023 through January 31, 2026 ​ $ 506.7 million 3.87 % ​ The gain or loss on the swaps is recognized in accumulated other comprehensive loss and reclassified into earnings as adjustments to interest expense in the same period or periods during which the swaps affect earnings.

Related Party Transactions At June 30, 2024 and December 31, 2023, we had $33.2 million and $65.3 million, respectively, of outstanding debt as part of the first lien term loan facility from Bain Affiliated Funds and CPPIB Credit Investments III Inc., affiliates of Bain Capital LP and Canada Pension Plan Investment Board (“Affiliated Debtholders”). Interest expense associated with and paid to Affiliated Debtholders was $1.3 million and $2.0 million for the three months ended June 30, 2024 and 2023, respectively, and $2.7 million and $4.4 million for the six months ended June 30, 2024 and 2023, respectively.

Participants may contribute a portion of their compensation to the plans, up to the maximum amount permitted under Section 401(k) of the Internal Revenue Code. Under these plans, we contribute various percentages of employees’ salaries to the plans. Total expenses included in operating expenses in the accompanying consolidated statement of operations related to the plans were $1.3 million and $1.0 million for the three months ended June 30, 2024 and 2023, respectively, and $2.4 million and $2.1 million for the six months ended June 30, 2024 and 2023, respectively.

Stock-based Compensation
Stock-based Compensation	15. Stock-based Compensation Equity incentive plans On October 22, 2019, the Board of Directors approved the Waystar Holding Corp. 2019 Stock Incentive Plan (“2019 Waystar Holding Plan”). Under this plan, we can issue up to 9.9 million options or other equity awards. The granted awards contain service criteria, performance criteria, market conditions, or a combination thereof for vesting and have a 10-year contractual term. Options with a service condition generally vest over 5 years with 20% vesting in equal vesting installments. Options with a performance condition and a market condition vest based upon a change in control, initial public offering, or a sponsor distribution or deemed return if the investors have achieved specified levels of return on investment. In addition, as part of a change in control in 2019, 3.8 million fully vested rollover options remain outstanding. The Board of Directors approved the Waystar Holding Corp. 2024 Equity Incentive Plan (the “2024 Equity Incentive Plan”), effective as of June 6, 2024, the date of pricing of our IPO. Under this plan, we can issue non-qualified stock options, incentive stock options, stock appreciation rights, restricted shares of the Company’s Common Stock, restricted stock units, and other equity-based awards tied to the value of the Company’s shares. Under this plan, we can issue up to 10 million options and other equity awards. The number of shares available to be issued automatically increases on the first day of each fiscal year beginning next year by a number of shares equal to the lesser of the positive difference, if any, between 5% of the outstanding common stock on the last day of the immediately preceding fiscal year, minus the plan share reserve on the last day of the immediately preceding fiscal year or such lesser number of shares as may be determined by the Board of Directors. Options with a service condition generally vest over 5 years with 20% vesting in equal vesting installments. The restricted stock units (“RSUs”) under the 2024 Equity Incentive Plan generally vest over 4 or 5 years with 25% or 20% vesting, respectively, in equal vesting installments. As of June 30, 2024, 4.7 million shares were available for future grants under the plan. The Board of Directors approved the Waystar Holding Corp. 2024 Employee Stock Purchase Plan (the “ESPP”), effective as of June 6, 2024, the date of pricing of our IPO On June 6, 2024, the effective date of our Prospectus, the Board of Directors approved the Waystar Holding Corp. 2024 Employee Stock Purchase Plan (the “ESPP”). A total of 3,250,000 shares of common stock are initially reserved for the ESPP. The number of shares available to be issued for the ESPP will automatically increase each fiscal year beginning next year by a number of shares equal to the lesser of the positive difference, if any, between 1% of the outstanding common stock on the last day of the immediately preceding fiscal year and the number of shares of common stock available for the issuance of shares pursuant to the plan on the last day of the immediately preceding fiscal year or such lesser number of shares as may be determined by the Board of Directors. The number of shares available to be issued for the ESPP will not exceed 27,000,000 as outlined in the plan agreement. As of June 30, 2024, the ESPP has not been made available to employees and no shares have been issued. Stock Options We utilize the Black-Scholes option pricing model to estimate the fair value of the service condition options under all plans and the Monte Carlo pricing model to estimate the fair value of the performance condition options under the 2019 Waystar Holding Corp. Plan. We value both types of options at the grant date using the following assumptions: ● Risk-free interest rate — reflects the average rate on the United States Treasury bond with maturity equal to the expected term of the option; ● Expected dividend yield — as we do not currently pay dividends or expect to pay dividends in the near future, the expected dividend yield is zero ; ● Expected term of stock award – under the 2024 Equity Incentive Plan, we utilized the simplified method due to the lack of historical experience activity for our Company. The simplified method calculates the expected term as the mid-point between the vesting date and the contractual expiration date of the award. Under the 2019 Waystar Holding Corp. Plan, it is based on historical experience that is modified based on expected future changes; ● Expected volatility in stock price — reflects the historical volatility of comparable public companies over the expected term of the stock option. The weighted average grant date fair value of options granted during the three months ended June 30, 2024 and 2023 was $12.59 and $19.58 per share, respectively. The weighted average grant date fair value of options granted during the six months ended June 30, 2024 and 2023 was $12.89 and $19.49 per share, respectively. As of June 30, 2024, we had 7.1 million fully vested options with a weighted average exercise price of $10.61 per share, an aggregate intrinsic value of $80.3 million and an average remaining contractual term of 4.4 years. The total fair value of options vested for the three months ended June 30, 2024 and 2023 were $0.5 million and $0.1 million, respectively. The total fair value of options vested for the six months ended June 30, 2024 and 2023 were $1.8 million and $1.3 million, respectively. We determined the vesting of all our performance condition options became probable as a result of the IPO (see Note 1). Therefore, we recognized an additional $33.1 million of stock-based compensation for the three and six months ended June 30, 2024 as the implicit service period for the awards established at the grant date had elapsed. As of June 30, 2024, there is no remaining unrecognized compensation expense related to the performance condition options issued under the 2019 Waystar Holding Corp. Plan.

Summary of Significant Accounting Policies
Basis of Financial Statement Presentation	Basis of Financial Statement Presentation The financial statements include the consolidated balance sheets, statements of operations, statements of comprehensive loss, statements of changes in stockholders’ equity, and statements of cash flows of Waystar and its subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The accompanying unaudited consolidated financial statements and notes have been prepared in accordance with GAAP and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the Company’s financial position, results of operations, changes in stockholders’ equity and cash flows. The results of operations for the six months ended June 30, 2024 are not necessarily indicative of the results for the full year or the results for any future periods. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes for the year ended December 31, 2023 in the prospectus filed with the SEC on June 6, 2024 (the “Prospectus”). We operate as a single business unit. As such, we report our results as a single operating segment that encompasses our entire organization.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Significant estimates and assumptions are used for, but are not limited to: (1) revenue recognition, including estimated expected customer life; (2) recoverability of accounts receivable and taxes receivable; (3) impairment assessment of goodwill and long-lived intangible assets; (4) fair value of intangibles acquired in business combinations; (5) litigation reserves; (6) depreciation and amortization; (7) fair value of stock options issued to employees and assumed as part of business combinations; (8) fair value of interest rate swaps; and (9) leases, including incremental borrowing rate. Future events and their effects cannot be predicted with certainty, and accordingly, accounting estimates require the exercise of judgment. We evaluate and update assumptions and estimates on an ongoing basis and may employ outside experts to assist in evaluations. Actual results could differ from the estimates used.
Revenue Recognition	Revenue Recognition We derive revenue primarily from providing access to our solutions for use in the healthcare industry and in doing so generate two types of revenue: (i) subscription revenue and (ii) volume-based revenue, which account for 99% of total revenue for all periods presented. We also derive revenue from implementation fees for our software, as well as hardware sales to facilitate patient payments. We recognize revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers ● identification of the contract, or contracts, with a client; ● 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; and ● recognition of revenue when, or as, we satisfy a performance obligation Our customers, referred to as clients elsewhere in this report, represent healthcare providers across all types of care settings, including physician practices, clinics, surgical centers, and laboratories, as well as large hospitals and health systems. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. The length of our contracts vary but are typically two three years Revenue from our subscription services as well as from our volume-based services represents a single promise to provide continuous access (i.e., a stand-ready obligation) to our software solutions in the form of a service. Our software products are made available to our clients via a cloud-based, hosted platform where our clients do not have the right or practical ability to take possession of the software. As each day of providing access to the software solutions is substantially the same and the client simultaneously receives and consumes the benefits as services are provided, these services are viewed as a single performance obligation comprised of a series of distinct daily services. Revenue from our subscription services is recognized over time on a ratable basis over the contract term beginning on the date that the service is made available to the client. Volume-based services are priced based on transaction, dollar volume or provider count in a given period. Given the nature of the promise is based on unknown quantities or outcomes of services to be performed over the contract term, the volume-based fee is determined to be variable consideration. The volume-based transaction fees are recognized each day using a time- elapsed output method based on the volume or transaction count at the time the clients’ transactions are processed. Our other services are generally related to implementation activities across all solutions and hardware sales to facilitate patient payments. Implementation services are not considered performance obligations as they do not provide a distinct service to clients without the use of our software solutions. As such, implementation fees related to our solutions are billed upfront and recognized ratably over the contract term. Implementation fees and hardware sales represent less than 1% of total revenue for all periods presented. Our contracts with clients typically include various combinations of our software solutions. Determining whether such software solutions are considered distinct performance obligations that should be accounted for separately versus together requires significant judgment. Specifically, judgment is required to determine whether access to the Company’s SaaS solutions is distinct from other services and solutions included in an arrangement. We follow the requirements of ASC 606-10-55-36 through -40, Revenue from Contracts with Customers, Principal Agent Considerations, in determining the gross versus net revenue presentations for our performance obligations in the contract with a client. Revenue recorded where we act in the capacity of a principal is reported on a gross basis equal to the full amount of consideration to which we expect in exchange for the good or service transferred. Revenue recorded where we act in the capacity of an agent is reported on a net basis, exclusive of any consideration provided to the principal party in the transaction. The principal versus agent evaluation is a matter of judgment that depends on the facts and circumstances of the arrangement and is dependent on whether we control the good or service before it is transferred to the client or whether we are acting as an agent of a third party. This evaluation is performed separately for each performance obligation identified. For the majority of our contracts, we are considered the principal in the transaction with the client and recognize revenue gross of any related channel partner fees or costs. We have certain agency arrangements where third parties control the goods or services provided to a client and we recognize revenue net of any fees owed to these third parties. Payment terms and conditions vary by contract type, although our standard payment terms generally require payment within 30 to 60 days. In instances where the timing of revenue recognition differs from the timing of payment, we have determined our contracts do not generally include a significant financing component. The primary purpose of our invoicing terms is to provide clients with simplified and predictable ways of purchasing our products and services, not to receive financing from our clients or to provide clients with financing.
Contract Costs	Contract Costs Incremental Costs of Obtaining a Contract Incremental costs of obtaining a contract primarily include commissions paid to our internal sales personnel. We consider all such commissions to be both incremental and recoverable since they are only paid when a contract is secured. These capitalized costs are amortized on a straight-line basis over the expected period of benefit, which is determined based on the average customer life, which includes anticipated renewals of contracts. As of June 30, 2024 and December 31, 2023, the total unamortized costs reported as deferred costs on our balance sheet amounted to $28.3 million and $22.8 million, respectively, for internal sales commissions. For the three months ended June 30, 2024 and 2023, amortization related to the sales commission asset was $2.6 million and $1.8 million, respectively. For the six months ended June 30, 2024 and 2023, amortization related to the sales commission asset was $5.0 million and $3.5 million, respectively. The aforementioned amortization amounts are included in sales and marketing in our consolidated statements of operations. Costs to Fulfill a Contract We capitalize costs incurred to fulfill contracts that i) relate directly to the contract, ii) are expected to generate resources that will be used to satisfy performance obligations under the contract, and iii) are expected to be recovered through revenue generated under the contract. Costs incurred to implement clients on our solutions (e.g., direct labor) are capitalized and amortized on a straight-line basis over the estimated customer life if we expect to recover those costs. As of June 30, 2024 and December 31, 2023, the total unamortized costs reported as deferred costs on our balance sheet amounted to $48.8 million and $43.0 million, respectively, for fulfillment costs. For the three months ended June 30, 2024 and 2023, amortization related to the fulfillment cost asset was $3.0 million and $2.1 million, respectively. For the six months ended June 30, 2024 and 2023, amortization related to the fulfillment cost asset was $5.7 million and $4.0 million, respectively. The aforementioned amortization amounts are included in the costs of revenue in our consolidated statements of operations. There were no impairment losses relating to deferred costs during the periods presented.
Channel Partners	Channel Partners We account for fees paid to channel partners within sales and marketing expenses in the accompanying statements of operations. For the three months ended June 30, 2024 and 2023, we recorded fees to all channel partners of $16.1 million and $13.0 million, respectively. For the six months ended June 30, 2024 and 2023, we recorded fees to all channel partners of $30.6 million and $25.8 million, respectively. As we are primarily responsible for contracting with and fulfilling contracts for the end user, we record revenue gross of related channel partner fees.
Deferred Offering Costs	Deferred Offering Costs We capitalize within other assets certain legal, accounting and other third-party fees that are directly related to our in-process equity financings, including the planned initial public offering, until such financings are consummated. After consummation of the equity financing, these costs are recorded as a reduction of the proceeds received as a result of the offering. Should a planned equity financing be abandoned, terminated or significantly delayed, the deferred offering costs are immediately written off to operating expenses. Through June 6, 2024, the effective date of our Prospectus, we had capitalized $8.8 million of deferred offering costs, which were charged to shareholders’ equity upon the completion of the IPO (see Note 1). As of December 31, 2023, deferred offering costs capitalized were $5.4 million.
Goodwill	Goodwill We account for business combinations under the acquisition method of accounting in accordance with Accounting Standards Codification (“ASC”) 805, Business Combinations, where the total purchase price is allocated to the tangible and identified intangible assets acquired and liabilities assumed based on their estimated fair values. The purchase price is allocated using the information currently available, and may be adjusted, up to one year from acquisition date, after obtaining more information regarding, among other things, asset valuations, liabilities assumed and revisions to preliminary estimates. The purchase price in excess of the fair value of the tangible and identified intangible assets acquired less liabilities assumed is recognized as goodwill. We account for goodwill under the provisions of ASC 350, Intangibles—Goodwill and Other. Goodwill is evaluated for impairment annually on October 1st or whenever there is an impairment indicator. There was no impairment to goodwill during the six months ended June 30, 2024 and 2023, respectively. Refer to Note 6 for more information on goodwill.
Debt Issuance Costs	Debt Issuance Costs Debt issuance costs, net of amortization, are reflected on our balance sheet as a direct reduction in the carrying amount of our long-term debt. In addition, debt issuance costs, net of amortization, related to our revolver debt are included in other assets. Debt issuance costs include fees paid to creditors and third party fees incurred for the issuance of new debt. Debt issuance costs are amortized over the respective term of the debt instruments using the effective interest method, and amortization charges are included in interest expense.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, “Segment Reporting-Improvements to Reportable Segment Disclosures.” The standard is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. For public business entities, the ASU will be effective for annual periods beginning after December 15, 2023. The guidance will be applied retrospectively unless it is impracticable to do so. Early adoption is permitted. We are currently evaluating the effect of the adoption of this amendment on our consolidated and condensed consolidated financial statements. In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, “Improvements to Income Tax Disclosures”, which requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. For public business entities, the ASU will be effective for annual periods beginning after December 15, 2024. The guidance will be applied on a prospective basis with the option to apply the standard retrospectively. Early adoption is permitted. We are currently evaluating the effect of the adoption of this amendment on our consolidated and condensed consolidated financial statements.
