Use of Non-GAAP financial measures

We believe that use of the Non-GAAP financial measures of adjusted pre-tax operating income (loss), adjusted net operating income (loss) and adjusted net operating income (loss) per diluted share facilitate the evaluation of the company's core financial performance thereby providing relevant information to investors. These measures are not recognized in accordance with accounting principles generally accepted in the United States of America (GAAP) and should not be viewed as alternatives to GAAP measures of performance.

Adjusted pre-tax operating income (loss) is defined as GAAP income (loss) before tax, excluding the effects of net realized investment gains (losses), gain and losses on debt extinguishment and infrequent or unusual non-operating items where applicable.

Adjusted net operating income (loss) is defined as GAAP net income (loss) excluding the after-tax effects of net realized investment gains (losses), gain and losses on debt extinguishment and infrequent or unusual non-operating items where applicable. The amounts of adjustments to components of pre-tax operating income (loss) are tax effected using a federal statutory tax rate of 21%.

Adjusted net operating income (loss) per diluted share is calculated in a manner consistent with the accounting standard regarding earnings per share by dividing (i) adjusted net operating income (loss) by (ii) diluted weighted average common shares outstanding, which reflects share dilution from unvested restricted stock units.

Although adjusted pre-tax operating income (loss) and adjusted net operating income (loss) exclude certain items that have occurred in the past and are expected to occur in the future, the excluded items represent items that are: (1) not viewed as part of the operating performance of our primary activities; or (2) impacted by both discretionary and other economic or regulatory factors and are not necessarily indicative of operating trends, or both. These adjustments, along with the reasons for their treatment, are described below. Trends in the profitability of our fundamental operating activities can be more clearly identified without the fluctuations of these adjustments. Other companies may calculate these measures differently. Therefore, their measures may not be comparable to those used by us.

(1)Net realized investment gains (losses). The recognition of net realized investment gains or losses can vary significantly across periods as the timing of individual securities sales is highly discretionary and is influenced by such factors as market opportunities, our tax and capital profile, and overall market cycles.

(2)Gains and losses on debt extinguishment. Gains and losses on debt extinguishment result from discretionary activities that are undertaken to enhance our capital position, and/or improve our debt profile.

(3)Infrequent or unusual non-operating items. Items that are non-recurring in nature and are not part of our primary operating activities.

NON-GAAP RECONCILIATIONS

(1) Total direct premiums earned, excluding premium refunds and accelerated premiums from single premium policy cancellations divided by average primary insurance in force.

(2) Premium refunds and our estimate of refundable premium on our delinquency inventory divided by average primary insurance in force.

(3) Ceded premiums earned, net of profit commissions and assumed premiums. Assumed premiums include our participation in GSE Credit Risk Transfer programs, of which the impact on the net premium yield was 0.3 bps in the second quarter of 2026.

(4) The credit score at the time of origination for a loan with multiple borrowers is the lowest of the borrowers’ “decision credit scores.” A borrower’s “decision credit score” is determined as follows: if there are three credit scores available, the middle credit score is used; if two credit scores are available, the lower of the two is used; if only one credit score is available, it is used.

(1) Items removed from inventory are associated with commutations of coverage on non-performing policies.

(1) Net paid claims, as presented, does not include amounts received in conjunction with terminations or commutations of reinsurance agreements.

(2) Excludes amounts paid in settlement disputes for claims paying practices and/or commutations of policies.

Safe Harbor Statement

Forward Looking Statements and Risk Factors:

This release contains forward looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. These statements are based on current assumptions, expectations, and projections and are subject to risks and uncertainties that could cause actual results to differ materially. Forward-looking statements consist of statements which relate to matters other than historical fact, including matters that inherently refer to future events. Among others, statements that include words such as "believe," "anticipate," "will" or "expect," or words of similar import, are forward-looking statements. Our actual results may differ, possibly materially, from those expressed or implied in such forward-looking statements. Factors and uncertainties that could cause actual results to differ can be found in the “Risk Factors” and “Forward-Looking Statements” sections included in MGIC Investment Corporation’s Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q. Such factors and uncertainties include, without limitation:

•Our results are dependent on U.S. economic and housing market conditions; adverse conditions may cause a decrease in new insurance written and/or an increase in delinquencies, claim frequency, and claim severity. Additionally, if the volume of low down payment home mortgage originations declines, the amount of new insurance that we write could decline.

•The substantial majority of MGIC’s new insurance written is for loans purchased by Fannie Mae and Freddie Mac (“the GSEs”); therefore, changes to their business practices or legislative, regulatory or administrative reforms could materially affect our business and financial results.

•Failure to comply with the GSEs’ Private Mortgage Insurance Eligibility Requirements (“PMIERs”) could limit our operations, or at the extreme, lead to suspension or termination of eligibility to insure loans purchased by the GSEs.

•Loss reserve estimates are subject to uncertainties; actual losses may differ materially from estimates. Additionally, because reserves are established only upon delinquency, losses may disproportionately impact earnings in certain periods.

•We operate in a highly regulated environment at both the federal and state levels; regulatory changes or enforcement actions may adversely affect our operations and/or financial results.

•If we fail to meet the State Capital Requirements of Wisconsin, we could be prevented from writing new business in all jurisdictions; we could be prevented from writing new business in a particular jurisdiction if we fail to meet the state capital requirements of that jurisdiction.

•Pandemics, severe weather events, and climate related developments may negatively affect home prices and affordability, potentially leading to an increase in delinquencies, claim frequency, and claim severity. Actions by government authorities, including FHFA and the GSEs, to address climate related issues could similarly affect our results.

•The availability, cost, and capital credit for reinsurance may change due to market conditions or GSE actions, potentially requiring us to retain more risk and maintain additional capital.

•Our financial results may be impacted if lenders and investors seek alternatives to private mortgage insurance. In addition, changes in GSE programs, growth in government market share, or changes to regulatory capital rules to limit capital relief for mortgage insurance could affect our business in similar ways.

•The premium rates we charge may prove inadequate due to unknown future economic conditions, modelling limitations or errors, or other unexpected events.

•The length of time our insurance policies remain in force (“persistency”) affects our results. Among other things, persistency can be influenced by interest rates, borrower equity, refinancing activity, and mortgage insurance cancellation requirements.

•Instability in financial markets or counterparty failures, including by reinsurers or mortgage servicers, could increase our credit risk and losses.

•Ineffective risk management programs, inaccurate data or model errors could impair our ability to identify and respond to risks, and materially adversely affect our business, results of operations, and financial condition.

•Technology system failures, cybersecurity breaches, or data privacy incidents could materially disrupt operations and cause financial and reputational damage.

•Changes in our underwriting practices and mix of business have the potential to increase risk and negatively affect our financial results.

•Our business depends on hiring and retaining experienced management and key personnel; the failure to do so could disrupt operations and negatively impact our financial condition.

•The mortgage insurance market is highly competitive. Competition from private mortgage insurers, government programs, and potential new market entrants —combined with pricing pressure and shifting customer preferences and relationships—could lead to a reduction in our new insurance written.

•Adverse rating agency actions could affect our competitiveness, GSE eligibility, and access to capital.

•Litigation and regulatory proceedings could result in fines, settlements, operational restrictions, or reputational harm.

•Our investment portfolio is exposed to risks that could adversely impact our operations and financial results. Future capital needs could require issuance of debt or equity, potentially diluting shareholders.

•Our stock price may fluctuate due to economic, industry, regulatory, or company specific developments.

•Regulatory limits on dividends from our insurance subsidiaries have the potential to constrain holding company liquidity and our ability to pay shareholder dividends or repurchase stock in the future.

We are not undertaking any obligation to update any forward-looking statements or other statements we may make even though these statements may be affected by events or circumstances occurring after the forward looking statements or other statements were made. No investor should rely on the fact that such statements are current at any time other than the time at which this press release was delivered for dissemination to the public.
