The information presented below is a summary only and should be read in conjunction with Mercury General's "Management's Discussion and Analysis of Financial Condition and Results of Operations" and Mercury General's consolidated financial statements and the related notes included in Mercury General's Annual Report on Form 10-K for the year ended December 31, 2025 and Quarterly Report on Form 10-Q for the quarter ended March 31, 2026.

The following tables reconcile the most directly comparable GAAP financial measures to each of these operating measures.

Net income (loss) is the GAAP measure that is most directly comparable to operating income (loss). Operating income (loss) is net income (loss) excluding realized investment gains and losses, net of tax. Operating income (loss) is used by management along with the other components of net income (loss) to assess the Company's performance. Management uses operating income (loss) as an important measure to evaluate the results of the Company's insurance business. Management believes that operating income (loss) provides investors with a valuable measure of the Company's ongoing performance as it reveals trends in the Company's insurance business that may be obscured by the effect of net realized investment gains and losses. Realized investment gains and losses may vary significantly between periods and are generally driven by external economic developments such as capital market conditions. Accordingly, operating income (loss) highlights the results from ongoing operations and the underlying profitability of the Company's core insurance business. Operating income (loss), which is provided as supplemental information and should not be considered as a substitute for net income (loss), does not reflect the overall profitability of the Company's business. It should be read in conjunction with the GAAP financial results.

Net premiums earned, the most directly comparable GAAP measure to net premiums written and direct premiums written, represents the portion of premiums written that is recognized as revenue in the financial statements for the periods presented and earned on a pro-rata basis over the term of the policies. Net premiums written is a statutory financial measure which represents the premiums charged on policies issued during a fiscal period net of any applicable reinsurance; direct premiums written is such a measure before any applicable reinsurance. Net premiums written and direct premiums written are designed to determine production levels and are meant as supplemental information and not intended to replace net premiums earned. Such information should be read in conjunction with the GAAP financial results.
