Unaudited Interim Financial Information

The interim condensed consolidated financial statements include the accounts of the Company, are prepared in conformity with U.S. generally accepted accounting principles (“GAAP”), and are unaudited. In the opinion of the Company’s management, all adjustments of a normal recurring nature necessary for a fair presentation have been reflected. Certain financial information that is normally included in annual financial statements prepared in accordance with GAAP, but that is not required for interim reporting purposes, has been omitted. The preparation of the interim condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the interim condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results and outcomes could differ from management’s estimates and assumptions. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

In 2022, the Board approved a stock repurchase program of up to $500.0 million. In the first quarter of 2025, the Board approved an increase of $600.0 million to the Company’s stock repurchase program bringing the total repurchase authorization up to $1.1 billion. During the three months ended March 31, 2025, the Company repurchased 1,193,011 shares for $389.8 million. The Company didnot execute any share repurchases during the three months ended March 31, 2024. As of March 31, 2025, the Company has remaining authorization of $344.8 million under the repurchase program.

On April 17, 2025, the Company's Board of Directors approved an increase of $1.0 billion to the Company's stock repurchase program.

Repurchases under the share repurchase program are executed in the open market or negotiated transactions under trading plans put in place pursuant to Rule 10b5-1. The Company constructively retired the repurchased shares associated with these approved share repurchases, except for a small portion which were retained as Treasury Shares on the condensed consolidated statements of shareholders' equity. Retired share repurchase amounts paid in excess of par value are reflected within Accumulated deficit/Retained earnings in the Company’s condensed consolidated balance sheets.

Recently Issued Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" which requires entities to enhance disclosures around income taxes. The guidance is effective for annual periods beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the effect this standard will have on its consolidated financial statements and related disclosures.

In November 2024, the FASB issued ASU 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses” to improve disclosures by

-8- providing more detailed information about the types of expenses in commonly presented expense captions. The guidance is effective for annual reporting periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the effect this standard will have on its consolidated financial statements and related disclosures.

(2)Net Income Per Share

Basic and diluted earnings or loss per share (“EPS”) are computed using the two-class method, which is an earnings allocation that determines EPS for each class of common stock and participating securities according to dividends declared and participation rights in undistributed earnings. The Company’s Restricted Stock Awards (“RSA”) are considered participating securities because they are legally issued at the date of grant and holders are entitled to receive non-forfeitable dividends during the vesting term.

The computation of diluted EPS includes additional common shares, such as unvested Restricted Stock Units (“RSU”) and stock options with exercise prices less than the average market price of the Company’s common stock during the period (“in-the-money options”), which would be considered outstanding. This assumes that additional shares would have to be issued in cases where the exercise price of stock options is less than the value of the common stock being acquired because the cash proceeds received from the stock option holder would not be sufficient to acquire that same number of shares. The Company does not compute diluted EPS in cases where the inclusion of such additional shares would be anti-dilutive in effect.

The following table sets forth the computation of basic and diluted earnings per share for the three months ended March 31, 2025 and 2024 (in thousands, except for earnings per share):

During the three months ended March 31, 2025 and 2024, the Company had (in thousands)80.1 and 0 stock options, respectively, that were excluded due to the exercise price exceeding the average fair value of the Company’s common stock during the period.

(3)Fair Value Measurements

The Company follows accounting guidance related to fair value measurements that defines fair value, establishes a framework for measuring fair value, and establishes a hierarchy for inputs used in measuring fair value. This hierarchy

-9- maximizes the use of “observable” inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. The hierarchy specifies three levels based on the inputs, as follows:

Level 1: Valuations based on quoted prices in active markets for identical assets or liabilities.

Level 2: Valuations based on directly observable inputs or unobservable inputs corroborated by market data.

Level 3: Valuations based on unobservable inputs supported by little or no market activity representing management’s determination of assumptions of how market participants would price the assets or liabilities.

The fair value of financial instruments such as cash and cash equivalents, accounts receivable and unbilled, net, accounts payable, accrued expenses and advanced billings approximate their carrying amounts due to their short term maturities.

The Company does not have material recurring fair value measurements as of March 31, 2025 and December 31, 2024. There were no material transfers between Level 1, Level 2 or Level 3 during the three months ended March 31, 2025 and 2024.
