Enact Holdings, Inc. Financial Supplement Third Quarter 2025 GAAP/Non-GAAP Disclosure Discussion This document includes the non-GAAP financial measures entitled “adjusted operating income (loss),” “adjusted operating income (loss) per share," and “adjusted operating return on equity." Adjusted operating income (loss) per share is derived from adjusted operating income (loss). Enact Holdings, Inc. (the "Company") defines adjusted operating income (loss) as net income (loss) excluding the after-tax effects of net investment gains (losses), restructuring costs, gains (losses) on debt extinguishment and infrequent or unusual non-operating items. The Company excludes net investment gains (losses), gains (losses) on the extinguishment of debt and infrequent or unusual non-operating items because the Company does not consider them to be related to the operating performance of the Company. The recognition of realized investment gains or losses can vary significantly across periods as the activity is highly discretionary based on the timing of individual securities sales due to such factors as market opportunities or exposure management. Trends in the profitability of our fundamental operating activities can be more clearly identified without the fluctuations of these realized gains and losses. We do not view them to be indicative of our fundamental operating activities. Therefore, these items are excluded from our calculation of adjusted operating income. In addition, adjusted operating income (loss) per share is derived from adjusted operating income (loss) divided by shares outstanding. Adjusted operating return on equity is calculated as annualized adjusted operating income for the period indicated divided by the average of current period and prior periods’ ending total stockholders’ equity. While some of these items may be significant components of net income (loss) in accordance with U.S. GAAP, the Company believes that adjusted operating income (loss) and measures that are derived from or incorporate adjusted operating income (loss), including adjusted operating income (loss) per share on a basic and diluted basis and adjusted operating return on equity, are appropriate measures that are useful to investors because they identify the income (loss) attributable to the ongoing operations of the business. Management also uses adjusted operating income (loss) as a basis for determining awards and compensation for senior management and to evaluate performance on a basis comparable to that used by analysts. Adjusted operating income (loss) and adjusted operating income (loss) per share on a basic and diluted basis are not substitutes for net income (loss) available to Company’s common stockholders or net income (loss) available to Company’s common stockholders per share on a basic and diluted basis determined in accordance with U.S. GAAP. In addition, the Company’s definition of adjusted operating income (loss) may differ from the definitions used by other companies. Adjustments to reconcile net income (loss) available to Company’s common stockholders to adjusted operating income (loss) assume a 21% tax rate. Page 2

Average paid claims in 3Q25 and each quarter of 2024 include payments in relation to agreements on non-performing loans. (2) Provides additional breakdown of incurred losses, which includes the impact of new delinquencies within each quarterly period reported. We believe providing loss information in this manner allows transparency and consistency for investors to understand performance. (3) Defaulted loans with most recent delinquency notice in the quarter indicated. (1) Direct primary case excludes loss adjustment expenses (LAE), pool, incurred but not reported (IBNR) and reinsurance reserves. (4) Development of current quarter delinquencies within the current quarter. This includes reserve impact from current period delinquencies that cure in the period and reserve development from the date of delinquency to quarter end. Page 10
