Enact Holdings, Inc. Financial Supplement Third Quarter 2021 Use of Non-GAAP Measures 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). The chief operating decision maker evaluates performance and allocates resources on the basis of adjusted operating income (loss). The company defines adjusted operating income (loss) as net income (loss) excluding the after-tax effects of net investment gains (losses), restructuring costs and infrequent or unusual non-operating items. The company excludes net investment gains (losses) and infrequent or unusual non-operating items because the company does not consider them to be related to the operating performance of the company and other activities. 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 Enact Holdings, Inc.’s common stockholders or net income (loss) available to Enact Holdings, Inc.’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 Enact Holdings, Inc.’s common stockholders to adjusted operating income (loss) assume a 21% tax rate. Page 2

(3)The PMIERs sufficiency ratio is calculated as available assets divided by required assets as defined within PMIERs. The current period PMIERs sufficiency ratio is an estimate due to the timing of the PMIERs filing and does not take into consideration the impact of restrictions recently imposed by the government-sponsored enterprises (GSEs). The GSEs have imposed certain capital restrictions on the company which remain in effect until certain conditions are met. These restrictions currently require GMICO to maintain 115% of published PMIERs minimum required assets among other restrictions. 20202021 Page 15
