Income Taxes

We have elected to treat PennyMac Corp. (“PMC”), as a TRS. Income from a TRS is only included as a component of REIT taxable income to the extent that the TRS makes dividend distributions of income to us. A TRS is subject to corporate federal and state income tax. Accordingly, a provision for income taxes for PMC is included in the accompanying consolidated statements of income.

The Company’s effective tax rate was 55.7% and (60.8)%with consolidated pretax income of $17.0 million and $10.7 million for the quarter and six months ended June 30, 2025. The Company’s TRS recognized a tax expense of $9.7 million on a pretax loss of $11.9 million and a tax benefit of $7.5 million on a pretax loss of $87.2 million for the quarter and six months ended June 30, 2025. For the same periods in 2024, the TRS recognized a tax expense of $3.0 million on pretax income of $9.9 million and a tax benefit of $12.0 million on a pretax loss of $51.0 million. The primary difference between the Company’s effective tax rate and the statutory tax rate is generally attributable to nontaxable REIT income resulting from the dividends paid deduction. The June 30, 2025 quarterly and six month results were impacted by the enactment of California Senate Bill 132, signed into law on June 27, 2025 and effective January 1,

2025. The law requires financial institutions to apportion their California income using a single sales factor instead of a factor equally weighted with property, payroll and sales. The change in apportionment method resulted in a higher provision tax rate and a repricing of the TRS’s net deferred tax liability.

The Company assesses the available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit use of the existing deferred tax assets. On the basis of this evaluation, as of June 30, 2025, the valuation allowance remains zero as a result of cumulative GAAP income at the TRS for the three-year period ended June 30, 2025. The amount of deferred tax assets considered realizable could be adjusted in future periods based on future income.

In general, cash dividends declared by the Company will be considered ordinary income to the shareholders for income tax purposes. Some portion of the dividends may be characterized as capital gain distributions or a return of capital. For tax years beginning after December 31, 2017, the 2017 Tax Cuts and Jobs Act (subject to certain limitations) provides a 20% deduction from taxable income for ordinary REIT dividends. One Big Beautiful Bill Act, signed into law on July 4, 2025, permanently extends the 20% deduction. The remainder of the Act’s provisions are not expected to have a material impact on the Company.
