For release July 30, 2025

(Cleveland, OH - July 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 nine months ended June 30, 2025.

“This quarter’s performance further reinforces my optimism for this year,” said Chairman and CEO Marc A. Stefanski. “Equity lines of credit originations have grown 17% from 2024, and our net interest margin improved six basis points this quarter to 1.81%, a nine quarter high. Our purchase mortgage activity is strong as we navigate a weaker-than-typical home buying season. Originations and acquired mortgage loans have totaled almost $700 million year-to-date. Our Tier 1 capital ratio of nearly 11% shows that we are well capitalized, and further demonstrates our strength and stability.”

The Company reported net income of $21.5 million for the quarter ended June 30, 2025 compared to net income of $21.0 million for the quarter ended March 31, 2025. The increase was mainly attributable to an increase in net interest income, partially offset by an increase in non-interest expense.

Net interest income increased $3.0 million, or 4.2%, to $75.0 million for the quarter ended June 30, 2025 from $72.0 million for the quarter ended March 31, 2025. The increase was primarily due to a ten basis point increase in the weighted average yield of interest-bearing assets, primarily loans, partially offset by a five basis point increase in the weighted average cost of interest-bearing liabilities. 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 equity loans and lines of credit. The interest rate spread for the quarter ended June 30, 2025 increased five basis points from the previous quarter, to 1.50%, and the net interest margin increased six basis points during the quarter to 1.81%.

The Company recorded a provision for credit losses of $1.5 million for both the quarter ended June 30, 2025 and the quarter ended March 31, 2025. The total allowance for credit losses increased $2.4 million during the quarter to $102.4 million, or 0.66% of total loans receivable, from $99.9 million, or 0.65% of total loans receivable, at March 31, 2025. The increase was primarily due to growth in the equity loans and lines of credit portfolios and a slight deterioration in economic factors utilized in estimating losses. The allowance for unfunded commitments, included in other liabilities, increased $0.4 million, to $29.8 million at June 30, 2025, from $29.4 million at March 31, 2025. Net recoveries were $0.9 million for the quarter ended June 30, 2025 compared to $0.7 million for the previous quarter.

Total non-interest expense increased $2.1 million, or 4.1%, to $53.2 million for the quarter ended June 30, 2025 from $51.1 million for the quarter ended March 31, 2025. The change included increases of $1.2 million in marketing services and $1.0 million in other expenses. Other expenses increased primarily due to a $1.0 million increase in costs related to originating loans, including appraisal and credit report fees and down payment assistance.

Total assets increased by $263.9 million to $17.38 billion at June 30, 2025 from $17.11 billion at March 31, 2025. The increase was mainly due to increases in loans held for investment and loans held for sale.

Loans held for investment, net of allowance and deferred loan expenses, increased $235.9 million, or 1.5%, to $15.60 billion at June 30, 2025 from $15.36 billion at March 31, 2025. During the quarter ended June 30, 2025, the combined balances of home equity loans and lines of credit increased $260.9 million to $4.58 billion and residential core mortgage loans decreased $25.0 million to $10.97 billion. Loans held for sale increased $25.2 million to $31.0 million at June 30, 2025, from $5.8 million at March 31, 2025, due to an increase in loans committed to future delivery contracts with Fannie Mae.

Deposits decreased $56.1 million, or less than 1%, to $10.34 billion at June 30, 2025, compared to $10.40 billion at March 31, 2025, consisting of a $20.4 million increase in certificates of deposit ("CDs") and decreases of $16.4 million in money market deposit accounts, $16.9 million in checking accounts, and $38.8 million in savings accounts.

Borrowed funds increased $295.7 million to $4.88 billion at June 30, 2025 from $4.59 billion at March 31, 2025. The increase was primarily used to fund growth in the loan portfolio. The total balance of borrowed funds at June 30, 2025, all from the FHLB, included $435.0 million of overnight advances, $1.51 billion of term advances with a weighted average maturity of approximately 1.8 years, and $2.93 billion of term advances aligned with interest rate swap contracts, with a remaining weighted average effective maturity of approximately 2.7 years. Additional borrowing capacity at the FHLB was $1.77 billion at June 30, 2025.

The Company reported net income of $65.0 million for the nine months ended June 30, 2025, an increase of $3.6 million compared to net income of $61.4 million for the nine months ended June 30, 2024. The increase was primarily due to increases in net interest income and non-interest income and a decrease in non-interest expense, partially offset by an increase in the provision for credit losses.

Net interest income increased $5.7 million, or 2.7%, to $215.4 million for the nine months ended June 30, 2025 compared to $209.7 million for the nine months ended June 30, 2024. The yield on interest-earning assets for the nine months ended June 30, 2025 increased 15 basis points compared to the same period a year ago, while the cost of interest-bearing liabilities increased 11 basis points. The interest rate spread was 1.43% for the nine months ended June 30, 2025 compared to 1.39% for the nine months ended June 30, 2024. The net interest margin was 1.74% for the nine months ended June 30, 2025 and 1.69% for the nine months ended June 30, 2024.

During the nine months ended June 30, 2025, there was a $1.5 million provision for credit losses compared to a $2.5 million release of provision for the nine months ended June 30, 2024. Net loan recoveries totaled $3.1 million for the nine months ended June 30, 2025 and $3.6 million for the same period in the prior year.

Due to the combined effect of the provision for credit losses and net loan recoveries during the nine months ended June 30, 2025, the total allowance for credit losses increased $4.6 million to $102.4 million, or 0.66% 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 equity lines of credit portfolio and commitments to originate both residential mortgage loans and equity loans and lines of credit. Also contributing to the increase was a slight deterioration in economic factors utilized to estimate losses. The allowance for credit losses included $29.8 million and $27.8 million in liabilities for unfunded commitments at June 30, 2025 and September 30, 2024, respectively. Total loan delinquencies increased to $34.3 million, or 0.22% of total loans receivable, at June 30, 2025 from $31.9 million, or 0.21% of total loans receivable, at September 30, 2024. Non-accrual loans totaled $37.3 million, or 0.24% of total loans receivable, at June 30, 2025, compared to $33.6 million, or 0.22% of total loans receivable, at September 30, 2024.

Total non-interest income increased $2.3 million, or 12.6%, to $20.6 million for the nine months ended June 30, 2025, from $18.3 million for the nine months ended June 30, 2024, primarily due to a $1.2 million increase in fees and service charges, net of amortization, and a $1.4 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 equity lines of credit.

Total non-interest expense decreased $1.1 million, or 0.7%, to $152.2 million for the nine months ended June 30, 2025, from $153.3 million for the nine months ended June 30, 2024. The decrease was mainly due to a decrease of $1.6 million in other expenses, partially offset by a $0.9 million increase in office property, equipment and software expenses. The decrease in other expenses included a $1.3 million positive change in net benefit related to the defined benefit plan.

Total assets increased $284.9 million, or 1.7%, to $17.38 billion at June 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 $273.9 million, or 1.8%, to $15.60 billion at June 30, 2025 from $15.32 billion at September 30, 2024. Home equity loans and lines of credit increased $690.8 million to $4.58 billion and the residential core mortgage loan portfolio decreased $415.2 million to $10.97 billion. Loans held for sale increased $13.2 million to $31.0 million at June 30, 2025 from $17.8 million at September 30, 2024. Loans originated and acquired during the nine months ended June 30, 2025 included $760.2 million of residential mortgage loans and $1.87 billion of equity loans and lines of credit compared to $598.7 million of residential mortgage loans and $1.62 billion of equity loans and lines of credit originated or acquired during the nine months ended June 30, 2024. Of the mortgage loans originated during the nine months ended June 30, 2025, 86% were purchases and 12% were adjustable rate loans.

Deposits increased $146.4 million, or 1.4%, to $10.34 billion at June 30, 2025 from $10.20 billion at September 30, 2024. The increase was the result of a $250.5 million increase in primarily retail certificates of deposit, partially offset by decreases of $26.7 million in savings accounts, $19.3 million in checking accounts and $49.7 million in money market deposit accounts. There were $976.5 million in brokered deposits at June 30, 2025 compared to $1.22 billion at September 30, 2024. The increase in retail certificate of deposit accounts was achieved through competitive rates and enhanced product offerings, supported by marketing efforts.

Borrowed funds increased $90.1 million, or 1.9%, to $4.88 billion at June 30, 2025 from $4.79 billion at September 30, 2024. The increase was primarily used to fund loan growth.

Total shareholders' equity increased $25.4 million, or 1.4%, to $1.89 billion at June 30, 2025 from $1.86 billion at September 30, 2024. Activity reflects $65.0 million of net income, dividends paid of $44.7 million, $0.7 million in repurchases of the Company's common stock, a $0.4 million net decrease in accumulated other comprehensive income and net positive adjustments of $6.3 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 nine months ended June 30, 2025, a total of 57,500 shares of the Company's common stock were repurchased at an average cost of $12.87 per share. The Company's eighth stock repurchase program allows for a total of 10,000,000 shares to be repurchased, with 5,134,451 remaining shares authorized for repurchase at June 30, 2025.

The Company declared and paid a quarterly dividend of $0.2825 per share during each of the first three fiscal quarters of 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. At a July 8, 2025 special meeting of members of the MHC, the members (depositors and certain loan customers of the Association) voted to approve the MHC’s proposed waiver of dividends, aggregating up to $1.13 per share, to be declared on the Company’s common stock during the twelve months subsequent to the members’ approval (i.e., through July 8, 2026). The MHC has filed a notice with, and a request for non-objection from, the Federal Reserve Bank of Cleveland for the proposed dividend waivers. Both the non-objection from the Federal Reserve Bank and the timing of the non-objection are unknown at this point. The MHC has conducted the member vote to approve the dividend waiver each of the past twelve years under Federal Reserve regulations and for each of those twelve years, approximately 97% of the votes cast were in favor of the waiver.

The Company operates under the capital requirements for the standardized approach of the Basel III capital framework

for U.S. banking organizations (“Basel III Rules”). At June 30, 2025 all of the Company's capital ratios exceed the amounts required for the Company to be considered "well capitalized" for regulatory capital purposes. The Company's Tier 1 leverage ratio was 10.86%, its Common Equity Tier 1 and Tier 1 ratios were each 17.75% and its total capital ratio was 18.61%.
