For release October 30, 2025

(Cleveland, OH - October 30, 2025) - TFS Financial Corporation (NASDAQ: TFSL) (the "Company", "we", "our"), the holding company for Third Federal Savings and Loan Association of Cleveland (the "Association"), today announced results for the quarter and fiscal year ended September 30, 2025.

“Third Federal saw record earnings of $91 million in our fiscal year, driven by a continued focus on improving our net interest margin, and an increase in first mortgage and home equity originations,” said Chairman and CEO Marc A. Stefanski. “Retail deposits stayed strong in fiscal year 2025, showing a $567 million increase. With confidence, we resumed stock buybacks, while continuing to report a Tier 1 capital ratio near 11%."

Net income grew by $4.5 million, or 20.9%, to $26.0 million for the quarter ended September 30, 2025 from $21.5 million for the quarter ended June 30, 2025. The increase was driven by increases in net interest income and non-interest income and decreases in the provision for credit losses and non-interest expense.

Net interest income increased $2.3 million, or 3.1%, to $77.3 million for the quarter ended September 30, 2025 from $75.0 million for the quarter ended June 30, 2025. The increase was primarily due to a 13 basis point increase in the weighted average yield on loans. Residential mortgage loans originated during a lower interest rate environment continue to amortize and be replaced with higher-yielding residential loans, including mortgage loans and home equity loans and lines of credit. The increase in loan yield was partially offset by an eight basis point increase in the weighted average cost of interest-bearing liabilities. The interest rate spread for the quarter ended September 30, 2025 increased four basis points from the previous quarter, to 1.54%, and the net interest margin increased three basis points during the quarter to 1.84%.

The Company recorded a provision for credit losses of $1.0 million for the quarter ended September 30, 2025 compared to $1.5 million for the quarter ended June 30, 2025. The total allowance for credit losses increased $2.0 million during the quarter to $104.4 million, or 0.67% of total loans receivable, from $102.4 million, or 0.66% of total loans receivable, at June 30, 2025. The increase was primarily due to growth in the home equity loan and lines of credit portfolios. The allowance for unfunded commitments, included in other liabilities, increased $0.3 million, to $30.1 million at September 30, 2025, from $29.8 million at June 30, 2025. Net recoveries were $1.0 million for the quarter ended September 30, 2025 compared to $0.9 million for the previous quarter.

Total non-interest income increased $1.2 million, or 17.0%, to $8.2 million for the quarter ended September 30, 2025 from $7.0 million for the quarter ended June 30, 2025. The increase was primarily due to a $1.6 million increase in net gain on the sale of loans, partially offset by a $0.5 million decrease in other non-interest income.

Total non-interest expense decreased $1.2 million, or 2.3%, to $52.0 million for the quarter ended September 30, 2025 from $53.2 million for the quarter ended June 30, 2025. The decrease was mainly due to a decrease of $1.3 million in marketing services which are expensed as incurred.

Total assets increased by $80.9 million to $17.46 billion at September 30, 2025 from $17.38 billion at June 30, 2025. The increase was mainly due to increases in loans held for investment and loans held for sale, partially offset by a decrease in cash and cash equivalents.

Cash and cash equivalents decreased $23.1 million, or 5.1%, to $429.4 million at September 30, 2025 from $452.6 million at June 30, 2025, due to normal fluctuations and liquidity management.

Loans held for investment, net of allowance and deferred loan expenses, increased $67.3 million, or less than 1%, to $15.66 billion at September 30, 2025 from $15.60 billion at June 30, 2025. During the quarter ended September 30, 2025, the combined balances of home equity loans and lines of credit increased $236.2 million to $4.81 billion and residential core mortgage loans decreased $166.1 million to $10.80 billion. Loans held for sale increased $26.7 million to $57.7 million at September 30, 2025, from $31.0 million at June 30, 2025, due to an increase in loans committed to future delivery contracts with Fannie Mae.

Deposits increased $105.5 million, or 1%, to $10.45 billion at September 30, 2025, compared to $10.34 billion at June 30, 2025, consisting of a $202.9 million increase in certificates of deposit ("CDs") and decreases of $15.1 million in money market deposit accounts, $24.8 million in checking accounts, and $57.4 million in savings accounts.

The Company reported net income of $91.0 million for the fiscal year ended September 30, 2025, an increase of $11.4 million, or 14.3%, compared to net income of $79.6 million for the fiscal year ended September 30, 2024. The increase was primarily driven by increases in net interest income and non-interest income, partially offset by an increase in the provision for credit losses.

Net interest income increased $14.2 million, or 5.1%, to $292.7 million for the fiscal year ended September 30, 2025 compared to $278.5 million for the fiscal year ended September 30, 2024. The yield on interest-earning assets for the fiscal year ended September 30, 2025 increased 15 basis points compared to the same period a year ago, while the cost of interest-bearing liabilities increased 8 basis points. The interest rate spread was 1.45% for the fiscal year ended September 30, 2025 compared to 1.38% for the fiscal year ended September 30, 2024. The net interest margin was 1.76% for the fiscal year ended September 30, 2025 and 1.69% for the fiscal year ended September 30, 2024.

During the fiscal year ended September 30, 2025, there was a $2.5 million provision for credit losses compared to a $1.5 million release of provision for the fiscal year ended September 30, 2024. Net loan recoveries totaled $4.0 million for the fiscal year ended September 30, 2025 and $4.7 million for the prior fiscal year.

The total allowance for credit losses increased $6.5 million to $104.4 million, or 0.67% of total loans receivable, from $97.8 million, or 0.64% of total loans receivable, at September 30, 2024. The increase was primarily related to increases in the home equity loan and lines of credit portfolios, as well as an increase in commitments to originate residential loans, including mortgage loans and home equity loans and lines of credit. The allowance for credit losses included $30.1 million and $27.8 million in liabilities for unfunded commitments at September 30, 2025 and September 30, 2024, respectively. Total loan delinquencies increased $2.8 million to $34.7 million, or 0.22% of total loans receivable, at September 30, 2025 from $31.9 million, or 0.21% of total loans receivable, at September 30, 2024. Non-accrual loans totaled $38.7 million, or 0.25% of total loans receivable, at September 30, 2025, compared to $33.6 million, or 0.22% of total loans receivable, at September 30, 2024.

Total non-interest income increased $4.1 million, or 16.6%, to $28.8 million for the fiscal year ended September 30, 2025, from $24.7 million for the fiscal year ended September 30, 2024, primarily due to a $1.4 million increase in fees and service charges, net of amortization, and a $2.6 million increase in net gain on the sale of loans. The increase in fees and service charges was mainly due to an increase in fee income earned on home equity lines of credit. During the fiscal years ended September 30, 2025 and 2024, there were $411.3 million and $247.4 million of loans sold with net gains on the sale of loans totaling $5.3 million and $2.6 million, respectively.

Total non-interest expense for the fiscal year ended September 30, 2025 was consistent with the prior fiscal year at $204.3 million. Compared to the prior fiscal year, there were increases of $1.7 million in salaries and employee benefits and $1.1 million in office property, equipment and software expenses, offset by decreases of $1.1 million in marketing services, $0.4 million in federal insurance premium and assessments and $1.2 million in other expenses. The decrease in other expenses included a $1.7 million positive change in net benefit related to the defined benefit plan, due to the expected return on plan assets exceeding the projected increase in benefit obligation. Additionally, there was a decrease of $0.8 million in down payment subsidies and increases of $0.6 million in each legal and professional consulting expenses.

Total assets increased $365.8 million, or 2.1%, to $17.46 billion at September 30, 2025 from $17.09 billion at September 30, 2024. The increase was mainly the result of an increase in loans held for investment.

Loans held for investment, net of allowance and deferred loan expenses, increased $341.3 million, or 2.2%, to $15.66 billion at September 30, 2025 from $15.32 billion at September 30, 2024.

Of the mortgage loans originated and acquired during the fiscal year ended September 30, 2025, 89% were purchases and 9% were adjustable rate loans.

Deposits increased $251.9 million, or 2.5%, to $10.45 billion at September 30, 2025 from $10.20 billion at September 30, 2024. The increase was the result of a $453.4 million increase in certificates of deposit, partially offset by decreases of $84.1 million in savings accounts, $44.1 million in checking accounts and $64.8 million in money market deposit accounts.

The increase in certificates of deposit was achieved through competitive rates and enhanced product offerings, supported by marketing efforts, and included a $768.9 million increase in retail certificates of deposit offset by a $315.5 million decrease in brokered accounts. There were $900.9 million in brokered certificates of deposit at September 30, 2025 compared to $1.22 billion at September 30, 2024.

Borrowed funds decreased $77.4 million, or 1.6%, to $4.87 billion at September 30, 2025 from $4.79 billion at September 30, 2024.

Activity reflects $91.0 million of net income, dividends paid of $59.7 million, $3.2 million in repurchases of the Company's common stock, a $5.6 million net decrease in accumulated other comprehensive income and net positive adjustments of $8.9 million related to our stock compensation and employee stock ownership plans. The change in accumulated other comprehensive income was primarily due to a net decrease in unrealized gains on swap contracts. During the fiscal year ended September 30, 2025, a total of 247,865 shares of the Company's common stock were repurchased at an average cost of $13.05 per share.

The Company declared and paid a quarterly dividend of $0.2825 per share during each quarter of fiscal year 2025. As a result of a mutual member vote, Third Federal Savings and Loan Association of Cleveland, MHC (the "MHC"), the mutual holding company that owns approximately 81% of the outstanding stock of the Company, was able to waive its receipt of its share of the dividends paid. Under Federal Reserve regulations, the MHC is required to obtain the approval of its members every 12 months for the MHC to waive its right to receive dividends. As a result of a July 8, 2025 member vote and subsequent non-objection of the Federal Reserve, the MHC has the approval to waive receipt of up to $1.13 per share of possible dividends to be declared on the Company’s common stock during the twelve months subsequent to the members’ approval (i.e., through July 8, 2026), including a total of up to $0.8475 remaining.
