Description of Business	Description of Business Sterling Check Corp. (the “Company”), a Delaware corporation headquartered in Independence, Ohio, is a global provider of technology-enabled background and identity verification services. The Company provides the foundation of trust and safety its clients need to create effective environments for their most essential resource—people. The Company offers a comprehensive hiring and risk management solution that begins with identity verification, followed by criminal background screening, credential verification, drug and health screening, employee onboarding document processing and ongoing risk monitoring. As of March 31, 2024, the Company is 51% owned by an investment group consisting of entities advised by or affiliated with The Goldman Sachs Group, Inc. (“Goldman Sachs”) and Caisse de dépôt et placement du Québec (“CDPQ” and, together with Goldman Sachs, our “Sponsor”).

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation and Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. These unaudited condensed consolidated financial statements are unaudited; however, in the opinion of management, they reflect all adjustments including those of a normal recurring nature necessary to state fairly the financial position, results of operations and cash flows for the periods presented in conformity with GAAP applicable to interim periods. The results of operations for the interim periods presented are not necessarily indicative of results for the full year or future periods. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements as of December 31, 2023 and notes thereto included in the Company’s Annual Report on Form 10-K filed with the SEC on March 6, 2024. Out-of-Period Adjustments The unaudited condensed consolidated financial statements for the three months ended March 31, 2024 include an adjustment of $4.0 million to increase selling, general and administrative expense and other current liabilities to correct for an error identified by management during the preparation of the unaudited condensed consolidated financial statements. The Company identified that the fair value of the contingent consideration related to the acquisition of Employment Background Investigations, Inc. (“EBI”) was understated by $4.0 million as of December 31, 2023. This out-of-period adjustment represents a correction of an understatement of expenses and an overstatement of net income of $2.0 million in each of the years ended December 31, 2023 and 2022 and an understatement of the related liabilities of $4.0 million and $2.0 million as of December 31, 2023 and 2022, respectively. In addition, the unaudited condensed consolidated financial statements for the three months ended March 31, 2024 include an adjustment of $0.7 million to increase the income tax benefit to correct for an error identified by management. This out-of-period adjustment represents a correction of an overstatement of the income tax provision for the year ended December 31, 2023.The Company evaluated the impact of these errors and out-of-period adjustments and concluded they are not material to any previously issued interim or annual consolidated financial statements and the adjustments are not expected to be material to the consolidated financial statements for the year ending December 31, 2024. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that can affect the reported amount of assets, liabilities, revenues, expenses and the disclosure of contingent assets and liabilities. Significant estimates include the impairment of long-lived assets, goodwill impairment, derivative instruments and hedging activities, and the determination of the fair value of acquired assets and liabilities. The Company believes that the estimates used in the preparation of these unaudited condensed consolidated financial statements are reasonable; however, actual results could differ materially from these estimates. Risks and Uncertainties The Company operates in an industry that is subject to intense competition, government regulation and rapid technological change. The Company’s operations are subject to significant risk and uncertainties including financial, operational, technological, regulatory, foreign operations, and other risks. Segment Information The Company has one operating and reportable segment. The Company’s chief operating decision maker is its Chief Executive Officer, who reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. Cash and Cash Equivalents Cash and cash equivalents of $67.0 million and $54.2 million as of March 31, 2024 and December 31, 2023, respectively, include money market instruments with maturities of three months or less. The Company maintained cash outside the U.S. as of March 31, 2024 of $23.4 million with the largest deposits being held in Australia and India, with balances of $6.7 million and $4.0 million, respectively. Cash outside the U.S. was $19.3 million as of December 31, 2023, with the largest deposits being held in Australia and India, with balances of $6.2 million and $3.2 million , respectively. Foreign Currency Assets and liabilities of operations having non-USD functional currencies are translated at period-end exchange rates, and income statement accounts are translated at weighted average exchange rates for the period. Gains or losses resulting from translating foreign currency financial statements, net of any related tax effects, are reflected in accumulated other comprehensive income or loss (“OCI”), a separate component of stockholders’ equity on the unaudited condensed consolidated balance sheets. Gains or losses resulting from foreign currency transactions incurred in currencies other than the local functional currency are included in other income in the unaudited condensed consolidated statements of operations and comprehensive loss. The cumulative translation adjustment resulted in losses of $5.1 million and $2.9 million as of March 31, 2024 and December 31, 2023, respectively. Accounts Receivable and Allowance for Credit Losses Accounts receivable balances consist of trade receivables that are recorded at the invoiced amount, net of allowances for expected credit losses and for potential sales credits and reserves. Sales credits and reserves were $0.7 million and $1.2 million as of March 31, 2024 and December 31, 2023 , respectively. The Company maintains an allowance for expected credit losses in order to record accounts receivable at their net realizable value. Inherent in the assessment of the allowance for expected credit losses are certain judgments and estimates relating to, among other things, the Company’s customers’ access to capital, customers’ willingness and ability to pay, general economic conditions and the ongoing relationship with customers. Allowances have been recorded for receivables believed to be uncollectible, including amounts for the resolution of potential credit and other collection issues such as disputed invoices. The allowance for expected credit losses is determined by analyzing the Company’s historical write-offs, the current aging of receivables, the financial condition of customers and the general economic climate. Adjustments to the allowance may be required in future periods depending on how such potential issues are resolved or if the financial condition of the Company’s customers were to deteriorate resulting in an impairment of their ability to make payments. The Company has not historically had material write-offs due to uncollectible accounts receivable. Allowances for expected credit losses were $2.9 million and $2.8 million as of March 31, 2024 and December 31, 2023, respectively. The following table summarizes changes in the allowance for expected credit losses for the periods presented: Three Months Ended (in thousands) 2024 2023 Balance as of beginning of period $ 2,816 $ 2,304 Additions 204 244 Write-offs, net of recoveries (82) (78) Foreign currency translation adjustment (5) 3 Balance as of end of period $ 2,933 $ 2,473 Corporate Technology and Production Systems Corporate technology and production systems includes costs related to maintaining the Company’s corporate information technology infrastructure and non-capitalizable costs to develop and maintain its production systems. The following table sets forth expenses included in each category of corporate technology and production systems for the periods presented: Three Months Ended (in thousands) 2024 2023 Corporate information technology $ 4,826 $ 5,267 Development of platform and product initiatives 5,560 4,414 Production support and maintenance 2,828 2,271 Total production systems 8,388 6,685 Total corporate technology and production systems $ 13,214 $ 11,952 Corporate information technology consists of salaries and benefits of personnel (including stock-based compensation expense) supporting internal operations such as information technology support and the maintenance of information security and business continuity functions. Also included are third-party costs including cloud computing costs that support the Company’s corporate internal systems, software licensing and maintenance, telecommunications and other technology infrastructure costs. Production systems costs consist of non-capitalizable personnel costs including contractor costs incurred for the development of platform and product initiatives and production support and maintenance. Platform and product initiatives facilitate the development of the Company’s technology platform and the launch of new screening products. Production support and maintenance includes costs to support and maintain the technology underlying the Company’s existing screening products and to enhance the ease of use of the Company’s cloud applications. Certain personnel costs related to new products and features are capitalized and amortized to depreciation and amortization. Included within corporate technology and production systems are non-capitalizable production system and corporate information technology expenses related to Project Ignite, a three-phase strategic investment initiative. Phase one of Project Ignite modernized client and candidate experiences and is complete. Phase two of Project Ignite focused on decommissioning the Company’s on-premises data centers and migrating the Company’s production systems and corporate information technological infrastructure to a managed service provider in the cloud. During the first half of 2021, the Company completed phase two initiatives related to the migration of its production and fulfillment systems to the cloud, and as a result, approximately 98% of revenue is processed through platforms hosted in the cloud. The Company incurred expenses related to phase two to complete the decommissioning of on-premises data centers for internal corporate technology infrastructure and migration to the cloud which was completed as of September 30, 2022. Phase three of Project Ignite was decommissioning of the platforms purchased over the prior ten years and the migration of the clients to one global platform. This third and final phase, which was completed in the first quarter of 2023, unified clients onto a single global platform. The Company’s core platform now processes approximately 77% of its global revenue.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Standards Updates	Recent Accounting Standards Updates The Company qualifies as an emerging growth company under the Jumpstart Our Business Startups Act (the “JOBS Act”).

Business Combination and Asset Acquisition [Abstract]
Acquisitions	Acquisitions Vault Acquisition On January 2, 2024, the Company acquired the equity interests of Vault Workforce Screening (“Vault”), a U.S. clinic management platform, bringing a network of 17,000 clinics and a flexible service model to enhance our existing drug and health services. The purchase price for the Vault acquisition totaled approximately $76.1 million, was funded with $65.0 million of proceeds from the Revolving Credit Facility and available cash on hand and includes initial contingent consideration of $2.8 million recorded at fair value. The Company incurred approximately $0.1 million of transaction expenses related to the Vault acquisition during the three months ended March 31, 2024. The preliminary allocation of the purchase price is based on the fair value of assets acquired and liabilities assumed as of the applicable acquisition date. The following table summarizes the consideration paid and the amounts recognized for the assets acquired and liabilities assumed (in thousands): Consideration Cash $ 2,907 Accounts receivable 8,514 Other current assets 583 Property and equipment 38 Intangible assets 44,500 Total assets acquired $ 56,542 Accounts payable and accrued expenses 4,609 Total liabilities assumed $ 4,609 Total identifiable net assets 51,933 Goodwill 24,203 Total consideration $ 76,136 Goodwill recognized is primarily attributable to assembled workforce and expected synergies and is tax deductible in future years. Intangible assets acquired consist largely of customer lists in the amount of $39.0 million to be amortized over 12 years. The remaining intangible assets include trade names and developed technology, which will be amortized over two years and seven years, respectively. As the acquisition of Vault occurred on January 2, 2024, Vault’s results have been fully consolidated in our unaudited condensed consolidated statement of operations and comprehensive loss for the three months ended March 31, 2024. Our revenues for the three months ended March 31, 2024 include $13.3 million of revenues attributable to Vault. The following unaudited pro forma results for the three months ended March 31, 2023 show the effect on the Company’s revenues as if the acquisition of Vault had occurred on January 1, 2023. The pro forma results presented are the result of combining the revenues of the Company with the revenues of Vault for the three months ended March 31, 2023: (in thousands) Three Months Ended March 31, 2023 Revenues $ 195,638 Pro forma net operating results are not presented as they were determined to not be material to the total net operating results of the Company. The Company did not have any material, non-recurring pro forma adjustments directly attributable to the business combination included in the reported pro forma revenue. The pro forma information is presented for illustrative purposes only and may not be indicative of the future results or results of operations that would have actually occurred had the acquisition of Vault occurred as presented. Further, the above pro forma amounts do not consider any potential synergies that may result from the transaction. In addition, future results may vary significantly from the results reflected in such pro forma information. Socrates and A-Check Acquisitions On January 4, 2023, the Company acquired all of the outstanding shares of Socrates Limited and its affiliates (“Socrates”), a screening company in Latin America, pursuant to a share purchase agreement. The Socrates acquisition expands the Company’s global presence into Latin America to serve the rapidly growing regional hiring needs of both multi-national and local clients. On March 1, 2023, the Company acquired all of the outstanding shares of A-Check Global (“A-Check”), a U.S.-based employment screening organization, pursuant to a share purchase agreement. The A-Check acquisition provides the Company access to a high quality, enterprise-focused customer base diversified across verticals including healthcare and telecom. The aggregate adjusted purchase price for the acquisitions totaled approximately $66.2 million, of which $49.5 million was funded with available cash on hand and is subject to certain closing adjustments specified in the share purchase agreements and includes initial contingent consideration related to the A-Check acquisition of $4.7 million recorded at fair value. The contingent consideration was determined based on actual future results. The initial fair value of the contingent consideration consisted of $2.6 million for an earn-out payable one year after the acquisition based upon revenue retention and a $2.1 million payable throughout the second and third year following the acquisition based on revenue retention and referral revenue. The Company recorded an allocation of the purchase price to assets acquired and liabilities assumed based on their estimated fair values as of their respective purchase dates. Additionally, in connection with the Socrates acquisition, $5.0 million is payable to certain senior employees two years after the acquisition date , based on certain retention requirements. The Company incurred approximately $0.2 million and $2.7 million of transaction expenses related to these acquisitions during the three months ended March 31, 2024 and March 31, 2023, respectively. The allocation of the purchase price is based on the fair value of assets acquired and liabilities assumed as of the applicable acquisition date.

Intangible assets acquired consist largely of customer lists in the amount of $28.0 million to be amortized over 15 years. The remaining intangible assets include trade names, developed technology and a non-compete agreement, which will be amortized over two years, eight years, and five years, respectively. The acquisitions are not material to the Company's financial position as of March 31, 2024 or results of operations for the three months ended March 31, 2024, and therefore, pro forma operating results and other disclosures for the acquisitions are not presented. EBI Acquisition On November 30, 2021, the Company acquired all of the outstanding shares of EBI for a purchase price of $67.8 million, consisting of $66.3 million of cash and $1.5 million of contingent consideration recorded at fair value.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is defined as the price that would be received to sell an asset or that would be paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. A three-level fair value hierarchy prioritizes the inputs used to measure fair value. An asset or liability’s level in the hierarchy is based on the lowest level of input that is significant to the fair value measurement. The three levels of inputs used to measure fair value are as follows: Level 1 Quoted prices in active markets for identical assets and liabilities. Level 2 Quoted prices in active markets for similar assets and liabilities, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flows methodologies and similar techniques that use significant unobservable inputs. The Company considers the recorded value of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses to approximate the fair value of the respective assets and liabilities as of March 31, 2024 and December 31, 2023 based upon the short-term nature of such assets and liabilities (Level 1). See Note 9, “Debt” for discussion of the fair value of the Company’s debt. Interest rate swaps are measured at fair value on a recurring basis in the Company’s financial statements and are considered Level 2 financial instruments. Interest rate swaps are measured based on quoted prices for similar financial instruments and other observable inputs recognized. The currency forward agreements are typically cash settled in U.S. dollars for their fair value at or close to their settlement date. Contingent consideration related to acquisitions is considered a Level 3 financial instrument. As of March 31, 2024, the fair value of contingent consideration related to the January 2, 2024 acquisition of Vault, the March 1, 2023 acquisition of A-Check and the November 30, 2021 acquisition of EBI. As of December 31, 2023, the fair value of contingent consideration related to the March 1, 2023 acquisition of A-Check and the November 30, 2021 acquisition of EBI. The contingent consideration consists of estimated future payments related to the Company’s acquisitions, based on metrics such as revenue retention and referral revenue. The fair value is determined using various assumptions and estimates, including revenue and customer projections to forecast a range of outcomes for the contingent consideration. The Company reassesses the estimated fair value of the contingent consideration at the end of each reporting period based on the information available at the time. Changes in the significant unobservable inputs used may result in a significantly higher or lower fair value measurement. Changes in fair value of contingent consideration are recorded in selling, general and administrative expense in the condensed consolidated statements of operations and comprehensive loss. The following tables present information about the Company’s financial assets and liabilities that are measured at fair value on a recurring basis and their assigned levels within the valuation hierarchy as of the periods presented: March 31, 2024 (in thousands) Level 1 Level 2 Level 3 Total Assets Cash equivalents from money market funds $ 13,600 $ — $ — $ 13,600 Interest rate swaps $ — $ 1,952 $ — $ 1,952 Liabilities Interest rate swaps — 2,061 — 2,061 Contingent consideration — — 9,739 9,739 December 31, 2023 (in thousands) Level 1 Level 2 Level 3 Total Assets Cash equivalents from money market funds 11,593 — — 11,593 Interest rate swaps — 1,187 — 1,187 Liabilities Interest rate swaps — 5,357 — 5,357 Contingent consideration $ — $ — $ 2,989 $ 2,989 The following table summarizes the change in fair value of the Level 3 liabilities with significant unobservable inputs for the periods presented: Three Months Ended (in thousands) 2024 2023 Fair value of contingent consideration, beginning of period $ 2,989 $ 1,219 Acquired liabilities 2,750 4,706 Cash payments — — Change in fair value of contingent consideration, net (1) 4,000 (305) Fair value of contingent consideration, end of period (2) $ 9,739 $ 5,620 _________________________ (1) During the three months ended March 31, 2024, the Company recorded a $4.0 million increase in the fair value of the contingent consideration, in accordance with the purchase agreement with EBI.

Based on current interest rates, during the next twelve months, the Company estimates that an additional $2.0 million net gain will be reclassified from accumulated OCI as a decrease to interest expense. No gain or loss was reclassified from accumulated OCI into earnings as a result of forecasted transactions that failed to occur during the periods presented.

Income Taxes	Income Taxes The computation of the provision for or benefit from income taxes for interim periods is determined by applying the estimated annual effective tax rate to year-to-date income before tax and adjusting for discrete tax items recorded in the period, if any. The Company recorded a tax benefit of $9.0 million for the three months ended March 31, 2024 and a tax expense of $1.1 million for the three months ended March 31, 2023, which resulted in an effective tax rate of 53.1% and 65.1%, respectively. For the three months ended March 31, 2024 and 2023, the effective rate differs from the statutory rate mainly due to a jurisdictional mix of earnings and permanent items including the impact of stock-based compensation.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Performance Obligations Substantially all of the Company’s revenues are recognized at a point in time as results from services are provided through a screening report and the customer takes control of the product when the report is completed. Accordingly, revenue is generally recognized at the point in time when the customer receives and can use the report. For revenue arrangements containing multiple products or services, the Company accounts for the individual products or services as separate performance obligations if they are distinct, the product or service is separately identifiable from other terms in the contract, and if a customer can benefit from it on its own or with other resources that are readily available to the customer. If these criteria are not met, the promised products or services are accounted for as a combined performance obligation. The Company allocates the contract price to each performance obligation based on the standalone selling prices of each distinct product or service in the contract. Disaggregation of Revenues The following tables set forth total revenue by type of service for the periods presented: Three Months Ended (in thousands) 2024 2023 Screening services $ 183,019 $ 176,871 Other services 2,980 2,403 Total revenue $ 185,999 $ 179,274 The following table sets forth total revenue by geographic area in which the revenues and invoicing are recorded for the periods presented: Three Months Ended (in thousands) 2024 2023 United States $ 159,827 $ 149,742 All other countries 26,172 29,532 Total revenue $ 185,999 $ 179,274 Other than the U.S., no single country accounted for more than 10% of the Company’s total revenues during the three months ended March 31, 2024 and 2023. Substantially all of the Company’s long-lived assets were located in the U.S. as of March 31, 2024 and December 31, 2023. Contract Assets and Liabilities The incremental costs of obtaining a contract with a customer are recognized as an asset if the benefit of such costs is expected to be longer than one year, with a majority of contracts being multi-year. Incremental costs include commissions to the sales force and are amortized over three years, as management estimates that this corresponds to the period over which a customer benefits from the contract. As of March 31, 2024 and December 31, 2023, $3.4 million of deferred commissions are included in other current assets on the unaudited condensed consolidated balance sheets and approximately $2.6 million and $2.7 million, respectively, of deferred commissions are included in other noncurrent assets, net on the unaudited condensed consolidated balance sheets. The Company did not have any material contract liabilities as of March 31, 2024 and December 31, 2023. Concentrations For the three months ended March 31, 2024 and 2023, no single customer accounted for more than 10% of the Company’s revenue. No single customer had an accounts receivable balance greater than 10% of total accounts receivable as of March 31, 2024 and December 31, 2023.

Basis of Presentation	Basis of Presentation and Consolidation These unaudited condensed consolidated financial statements are unaudited; however, in the opinion of management, they reflect all adjustments including those of a normal recurring nature necessary to state fairly the financial position, results of operations and cash flows for the periods presented in conformity with GAAP applicable to interim periods. The results of operations for the interim periods presented are not necessarily indicative of results for the full year or future periods. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements as of December 31, 2023 and notes thereto included in the Company’s Annual Report on Form 10-K filed with the SEC on March 6, 2024.
Consolidation	All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that can affect the reported amount of assets, liabilities, revenues, expenses and the disclosure of contingent assets and liabilities. Significant estimates include the impairment of long-lived assets, goodwill impairment, derivative instruments and hedging activities, and the determination of the fair value of acquired assets and liabilities. The Company believes that the estimates used in the preparation of these unaudited condensed consolidated financial statements are reasonable; however, actual results could differ materially from these estimates.
Risks And Uncertainties	Risks and Uncertainties The Company operates in an industry that is subject to intense competition, government regulation and rapid technological change. The Company’s operations are subject to significant risk and uncertainties including financial, operational, technological, regulatory, foreign operations, and other risks.

Foreign Currency	Foreign Currency
Accounts Receivable and Allowance for Credit Losses	Accounts Receivable and Allowance for Credit Losses Accounts receivable balances consist of trade receivables that are recorded at the invoiced amount, net of allowances for expected credit losses and for potential sales credits and reserves. Sales credits and reserves were $0.7 million and $1.2 million as of March 31, 2024 and December 31, 2023 , respectively. The Company maintains an allowance for expected credit losses in order to record accounts receivable at their net realizable value. Inherent in the assessment of the allowance for expected credit losses are certain judgments and estimates relating to, among other things, the Company’s customers’ access to capital, customers’ willingness and ability to pay, general economic conditions and the ongoing relationship with customers. Allowances have been recorded for receivables believed to be uncollectible, including amounts for the resolution of potential credit and other collection issues such as disputed invoices. The allowance for expected credit losses is determined by analyzing the Company’s historical write-offs, the current aging of receivables, the financial condition of customers and the general economic climate. Adjustments to the allowance may be required in future periods depending on how such potential issues are resolved or if the financial condition of the Company’s customers were to deteriorate resulting in an impairment of their ability to make payments. The Company has not historically had material write-offs due to uncollectible accounts receivable.
Corporate Technology and Production Systems	Corporate Technology and Production Systems Corporate technology and production systems includes costs related to maintaining the Company’s corporate information technology infrastructure and non-capitalizable costs to develop and maintain its production systems. Corporate information technology consists of salaries and benefits of personnel (including stock-based compensation expense) supporting internal operations such as information technology support and the maintenance of information security and business continuity functions. Also included are third-party costs including cloud computing costs that support the Company’s corporate internal systems, software licensing and maintenance, telecommunications and other technology infrastructure costs. Production systems costs consist of non-capitalizable personnel costs including contractor costs incurred for the development of platform and product initiatives and production support and maintenance. Platform and product initiatives facilitate the development of the Company’s technology platform and the launch of new screening products. Production support and maintenance includes costs to support and maintain the technology underlying the Company’s existing screening products and to enhance the ease of use of the Company’s cloud applications. Certain personnel costs related to new products and features are capitalized and amortized to depreciation and amortization. Included within corporate technology and production systems are non-capitalizable production system and corporate information technology expenses related to Project Ignite, a three-phase strategic investment initiative. Phase one of Project Ignite modernized client and candidate experiences and is complete. Phase two of Project Ignite focused on decommissioning the Company’s on-premises data centers and migrating the Company’s production systems and corporate information technological infrastructure to a managed service provider in the cloud. During the first half of 2021, the Company completed phase two initiatives related to the migration of its production and fulfillment systems to the cloud, and as a result, approximately 98% of revenue is processed through platforms hosted in the cloud. The Company incurred expenses related to phase two to complete the decommissioning of on-premises data centers for internal corporate technology infrastructure and migration to the cloud which was completed as of September 30, 2022. Phase three of Project Ignite was decommissioning of the platforms purchased over the prior ten years and the migration of the clients to one global platform. This third and final phase, which was completed in the first quarter of 2023, unified clients onto a single global platform. The Company’s core platform now processes approximately 77% of its global revenue.
