⁽¹⁾	These measures are not based on U.S. generally accepted accounting principles (“GAAP”), are defined in “Information Regarding GAAP and Non-GAAP Measures” and are reconciled to the most directly comparable GAAP measures in “Supplemental Schedules.”

⁽²⁾

Both net premiums earned and net premiums written for the nine months ended September 30, 2025 include $101 million of increased ceded premiums due to the reinstatement premiums paid and recorded in the first half of 2025 to reinstate the fully exhausted reinsurance coverage layers of its catastrophe reinsurance treaty ended June 30, 2025 following the Palisades and Eaton wildfires in January 2025.

⁽³⁾

Net realized investment (losses) gains before tax was $(262) million and $84 million for the three months ended September 30, 2026 and 2025, respectively, and $(180) million and $131 million for the nine months ended September 30, 2026 and 2025, respectively. Net realized investment losses for the three and nine months ended September 30, 2026 resulted largely from the decreases in fair value of the Company’s investments during the third quarter of 2026 primarily caused by large increases in overall market interest rates. The changes in fair value of the Company’s investments are recorded as part of net realized investment gains or losses in its consolidated statements of operations due to the adoption of the fair value option under GAAP.

⁽⁴⁾	The majority of 2026 catastrophe losses resulted from storms in Oklahoma and Texas and adverse reserve development on the Palisades and Eaton wildfires. The majority of 2025 catastrophe losses resulted from the Palisades and Eaton wildfires in California and storms in Texas and Oklahoma.

⁽⁵⁾

The Company experienced favorable development of approximately $58 million and $27 million on prior accident years’ loss and loss adjustment expense reserves for the three months ended September 30, 2026 and 2025, respectively, and favorable development of approximately $102 million and $74 million on prior accident years’ loss and loss adjustment expense reserves for the nine months ended September 30, 2026 and 2025, respectively. The year-to-date favorable development in 2026 was primarily attributable to lower than estimated losses and loss adjustment expenses in the automobile line of insurance business, partially offset by adverse development on the homeowners line of insurance business primarily related to the Palisades and Eaton wildfires. The year-to-date favorable development in 2025 was primarily attributable to lower than estimated losses and loss adjustment expenses in the automobile and homeowners lines of insurance business.

⁽¹⁾	Fixed maturities and short-term bonds at amortized cost; equities and other short-term investments at cost. Average invested assets at cost are based on the monthly amortized cost of the invested assets excluding cash for each period.

⁽²⁾

Net investment income includes interest income earned on cash of approximately $12.0 million and $12.9 million ($9.5 million and $10.2 million after tax) for the three months ended September 30, 2026 and 2025, respectively, and approximately $35.1 million and $38.4 million ($27.7 million and $30.4 million after tax) for the nine months ended September 30, 2026 and 2025, respectively. Average annual yield on investments does not include interest income earned on cash.

⁽³⁾

Higher net investment income before and after income taxes for the three and nine months ended September 30, 2026 compared to the corresponding periods in 2025 resulted largely from higher average invested assets, partially offset by decreases in average annual yield on investments and interest income earned on cash before and after taxes. Average annual yield on investments before income taxes for the three months ended September 30, 2026 decreased from the corresponding period in 2025, primarily due to an increase in tax-exempt investments with lower pre-tax yields combined with lower yields on floating rate investments resulting from lower short-term market interest rates, partially offset by higher yields on long-term investments. Average annual yield on investments after income taxes for the three months ended September 30, 2026 decreased from the corresponding period in 2025, primarily due to lower yields on floating rate investments resulting from lower short-term market interest rates, partially offset by higher yields on long-term investments. Average annual yield on investments before income taxes for the nine months ended September 30, 2026 decreased from the corresponding period in 2025, primarily due to an increase in tax-exempt investments with lower pre-tax yields combined with lower yields on floating rate investments resulting from lower short-term market interest rates. Average annual yield on investments after income taxes for the nine months ended September 30, 2026 decreased from the corresponding period in 2025, primarily due to lower yields on floating rate investments resulting from lower short-term market interest rates.

The Board of Directors declared a quarterly dividend of $0.3175 per share. The dividend will be paid on December 31, 2026 to shareholders of record on December 17, 2026.

Information Regarding GAAP and Non-GAAP Measures

The Company has presented information within this document containing operating measures which in management’s opinion provide investors with useful, industry specific information to help them evaluate, and perform meaningful comparisons of, the Company’s performance, but that may not be presented in accordance with GAAP. These measures are not intended to replace, and should be read in conjunction with, the GAAP financial results.

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. See “Supplemental Schedules” above for a reconciliation of net income (loss) to operating income (loss).

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. See “Supplemental Schedules” above for a reconciliation of net premiums earned to net premiums written and direct premiums written.

Incurred losses and loss adjustment expenses is the most directly comparable GAAP measure to paid losses and loss adjustment expenses. Paid losses and loss adjustment expenses excludes the effects of changes in the loss reserve accounts. Paid losses and loss adjustment expenses is provided as supplemental information and is not intended to replace incurred losses and loss adjustment expenses. It should be read in conjunction with the GAAP financial results. See “Supplemental Schedules” above for a reconciliation of incurred losses and loss adjustment expenses to paid losses and loss adjustment expenses.

Combined ratio is the most directly comparable measure to combined ratio-accident period basis. Combined ratio-accident period basis is computed as the difference between two GAAP operating ratios: the combined ratio and prior accident periods’ loss development ratio. Management believes that combined ratio-accident period basis is useful to investors and it is used to reveal the trends in the Company’s results of operations that may be obscured by development on prior accident periods’ loss reserves. Combined ratio-accident period basis is meant as supplemental information and is not intended to replace the GAAP combined ratio. It should be read in conjunction with the GAAP financial results. See “Supplemental Schedules” above for a reconciliation of GAAP combined ratio to combined ratio-accident period basis.
