Income Taxes

We have elected to treat PennyMac Corp. (“PMC”) as a taxable REIT subsidiary (“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 operations.

The Company’s effective tax rate was (54.3)% and (10.5)% with consolidated pretax loss of $16.4 million and pretax income of $27.3 million for the quarter and nine months ended September 30, 2026, respectively. The Company’s TRS recognized a tax expense of $10.1 million on pretax income of $41.1 million and tax benefit of $1.2 million on a pretax loss of $13.3 million for the quarter and nine months ended September 30, 2026, respectively. For the same periods in 2025, the TRS recognized a tax benefit of $11.2 million on a pretax loss of $43.8 million and a tax benefit of $18.7 million on a pretax loss of $131.0 million, respectively. 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 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 September 30, 2026, the valuation allowance remains zero. The TRS has a significant net deferred tax liability position, which indicates the TRS will utilize all of its deferred tax assets. 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. The 2017 Tax Cuts and Jobs Act (subject to certain limitations) provides a 20% deduction from taxable income for ordinary REIT dividends which was made permanent under the One Big Beautiful Bill Act of 2025.
