HOQUIAM, WA – October 30, 2025 – Timberland Bancorp, Inc. (NASDAQ: TSBK) (“Timberland” or “the Company”), the holding company for Timberland Bank (the “Bank”), today reported that net income increased 20% to $29.16 million for the fiscal year ended September 30, 2025, from $24.28 million for the fiscal year ended September 30, 2024.  Earnings per diluted common share (“EPS”) increased 22% to $3.67 for the 2025 fiscal year from $3.01 for the 2024 fiscal year.

Timberland also reported net income of $8.45 million, or $1.07 per diluted common share for the quarter ended September 30, 2025.  This compares to net income of $7.10 million, or $0.90 per diluted common share for the preceding quarter, and $6.36 million, or $0.79 per diluted common share, for the comparable quarter one year ago.

“We closed our fiscal year with record results, reflecting the hard work and dedication of our employees in serving our customers, communities and shareholders,” stated Dean Brydon, Chief Executive Officer.  “For the full year, net income and earnings per share reached new highs with year-over-year gains across every major profitability measure, while tangible book value per share continued its steady climb.  In the fourth quarter, net income increased 33% from a year ago and 19% from the prior quarter, with earnings per share up 35% and 19%, respectively.  We also recorded a $1.04 million bank owned life insurance benefit claim during the quarter, which contributed to net income; however, even excluding this item, all comparisons to prior periods remain favorable.  These strong quarterly results were driven by continued expansion in our net interest margin, balance sheet growth, and higher non-interest income.”

“As a result of Timberland’s strong earnings and capital position, our Board of Directors announced an 8% increase to the quarterly cash dividend to shareholders to $0.28 per share, payable on November 28, 2025, to shareholders of record on November 14, 2025,” stated Jonathan Fischer, President and Chief Operating Officer.  “This represents the 52nd consecutive quarter Timberland will have paid a cash dividend and demonstrates the Board’s continued confidence in our long-term outlook.”

“Our net interest margin strengthened again in the fourth fiscal quarter, increasing to 3.82%,” said Marci Basich, Chief Financial Officer.  “This marks a two-basis point increase from the prior quarter and a 24-basis point improvement year-over- year, underscoring the benefits of our disciplined asset-liability management and the improvement in earning asset yields.  Total deposits increased by $47 million, or 3%, with more than half of that growth driven by higher non-interest-bearing balances.  This continued deposit momentum reflects the depth of our customer relationships and the success of our funding strategies.  We remain committed to maintaining a balanced funding profile and sustaining stable margin performance in the periods ahead.”

“Timberland delivered solid balance sheet growth during the fourth fiscal quarter, highlighted by total assets increasing 3% and surpassing the $2 billion dollar mark for the first time in our Company’s history,” Brydon continued.  “Credit quality remains an area we continue to monitor closely.  Overall, performance across the portfolio remains solid, with no net charge-offs for the quarter.  While our non-performing assets (“NPA”) ratio increased modestly to 0.23% at September 30, 2025 from 0.21% in the prior quarter, we also saw total delinquencies decline during the period.  We remain confident in the overall health of our loan portfolio and our disciplined approach to credit risk management.”

“We are excited to announce the opening of a new full-service branch in University Place later this quarter, marking an important milestone in our growth strategy,” said Fischer.  “This expansion positions us to serve a growing market with strong business potential and deepen our commercial banking relationships in the area.  We are enthusiastic about the opportunities ahead to welcome new clients, strengthen existing partnerships, and further advance our commitment to supporting the region’s economic growth,” stated Matt DeBord, Chief Lending Officer.

Operating revenue (net interest income before the provision for credit losses plus non-interest income) for the current quarter increased 10% to $22.49 million from $20.50 million for the preceding quarter and increased 15% from $19.48 million for the comparable quarter one year ago.  The increase in operating revenue compared to the preceding quarter was primarily due to increases in non-interest income and interest income from loans and interest-bearing deposits in banks, which were partially offset by an increase in total funding costs.  The increase in non-interest income was primarily due to a $1.04 million bank owned life insurance (“BOLI”) death benefit claim.  Operating revenue increased 10% to $82.55 million for the 2025 fiscal year from $75.30 million for the 2024 fiscal year, primarily due to an increase in total interest and dividend income, which was partially offset by an increase in funding costs.

Net interest income increased $773,000, or 4%, to $18.40 million for the current quarter from $17.62 million for the preceding quarter and increased $1.85 million, or 11%, from $16.55 million for the comparable quarter one year ago.  The increase in net interest income compared to the preceding quarter was primarily due to a $48.52 million increase in the average balance of total interest-earning assets and, to a lesser extent, a three-basis point increase in the weighted average yield on total interest-earning assets to 5.53% from 5.50%.  These increases were partially offset by a $21.64 million increase in the average balance of interest-bearing liabilities and a two-basis point increase in the weighted average cost of interest-bearing liabilities.  Timberland’s NIM for the current quarter improved to 3.82% from 3.80% for the preceding quarter and 3.58% for the

comparable quarter one year ago.  The NIM for the current quarter was increased by approximately two basis points due to the collection of $102,000 in pre-payment penalties, non-accrual interest, and late fees, and the accretion of $11,000 of the fair value discount on acquired loans.  The NIM for the preceding quarter was increased by approximately four basis points due to the collection of $102,000 in pre-payment penalties, non-accrual interest, and late fees, and the accretion of $68,000 of the fair value discount on acquired loans.  The NIM for the comparable quarter one year ago was increased by approximately one basis point due to the collection of $20,000 in pre-payment penalties, non-accrual interest, and late fees, and the accretion of $7,000 of the fair value discount on acquired loans.

Net interest income for the 2025 fiscal year increased $6.03 million, or 9%, to $70.20 million from $64.17 million for the 2024 fiscal year, primarily due to a 24-basis point increase in the weighted average yield of total interest-earning assets to 5.48% from 5.24% and a $55.19 million increase in the average balance of total interest-earning assets.  These increases to net interest income were partially offset by a $54.78 million increase in the average balance of total interest-bearing liabilities. Timberland’s NIM improved to 3.76% for the 2025 fiscal year from 3.54% for the 2024 fiscal year.  A $213,000 provision for credit losses on loans was recorded for the quarter ended September 30, 2025.  The provision was primarily due to loan portfolio growth and changes in the composition of the loan portfolio.  This compares to a $351,000 provision for credit losses on loans for the preceding quarter and a $444,000 provision for credit losses on loans for the comparable quarter one year ago.  In addition, a $18,000 provision for credit losses on unfunded commitments and a $10,000 recapture of credit losses on investment securities were recorded for the current quarter.

Non-interest income increased $1.22 million, or 42%, to $4.09 million for the current quarter from $2.88 million for the preceding quarter and increased $1.16 million, or 40%, from $2.93 million for the comparable quarter one year ago.  The increase in non-interest income compared to the preceding quarter was primarily due to an increase in BOLI net income (from a $1.04 million death benefit claim) and, to a lesser extent, smaller increases in several other categories.  Non-interest income for the 2025 fiscal year increased $1.22 million, or 11%, to $12.35 million for the 2025 fiscal year from $11.14 for the 2024 fiscal year, primarily due to a $1.06 million increase in BOLI net earnings and smaller changes in several other categories.

Total operating (non-interest) expenses for the current quarter increased $792,000, or 7%, to $11.96 million from $11.17 million for the preceding quarter and increased $897,000, or 8%, from $11.06 million for the comparable quarter one year ago.  The increase in operating expenses compared to the preceding quarter was primarily due to increases in salaries and employee benefits, premises and equipment, technology and communications, professional fees, and smaller increases in several other expense categories.  These increases were partially offset by decreases in state and local taxes and smaller decreases in several other expense categories.  The efficiency ratio for the current quarter improved to 53.18% from 54.48% for the preceding quarter and 56.79% for the comparable quarter one year ago.  For the 2025 fiscal year, operating expenses increased $1.64 million, or 4% to $45.39 million from $43.75 million for the 2024 fiscal year. The efficiency ratio for the 2025 fiscal year improved to 54.98% from 58.09% for the 2024 fiscal year.

The provision for income taxes for the current quarter increased $71,000, or 4%, to $1.86 million from $1.79 million for the preceding quarter, primarily due to higher taxable income. Timberland’s effective income tax rate was 18.1% for the quarter ended September 30, 2025, compared to 20.1% for the quarter ended June 30, 2025, and 19.8% for the quarter ended September 30, 2024.  The lower effective income tax rate for the current quarter was primarily due to a higher percentage of non-taxable income as a result of the increase in BOLI net earnings.  Timberland’s effective income tax rate was 19.5% for fiscal year 2025 compared to 20.1% for fiscal year 2024.

Total assets increased $55.58 million, or 3%, during the quarter to $2.01 billion at September 30, 2025, from $1.96 billion at June 30, 2025, and increased $89.30 million, or 5%, from $1.92 billion one year ago.  The increase during the current quarter was primarily due to a $49.80 million increase in cash and cash equivalents and a $22.09 million increase in net loans receivable, which was partially offset by a $14.18 million decrease in investment securities and CDs held for investment.

Liquidity

Timberland has continued to maintain a strong liquidity position, both on-balance sheet and off-balance sheet.  Liquidity, as measured by the sum of cash and cash equivalents, CDs held for investment, and available for sale investment securities, was 18.8% of total liabilities at September 30, 2025, compared to 17.0% at June 30, 2025, and 14.7% one year ago.  Timberland also had secured borrowing line capacity of $690 million available through the FHLB and the Federal Reserve at

September 30, 2025.  With a strong and diversified deposit base, only 20% of Timberland’s deposits were uninsured or uncollateralized at September 30, 2025.  (Note: This calculation excludes public deposits that are fully collateralized.)

Loans

Net loans receivable increased $22.09 million, or 2%, during the quarter to $1.46 billion at September 30, 2025, from $1.44 billion at June 30, 2025.  This increase was primarily due to a $21.21 million increase in construction loans, a $7.35 million increase in multi-family loans, a $2.99 million increase in home equity loans, a $2.77 million increase in commercial real estate loans and smaller increases in several other loan categories.  These increases were partially offset by a $12.02 million increase in the undisbursed portion of construction loans and smaller decreases in several other loan categories.

CRE Loan Portfolio Breakdown by Collateral

($ in thousands)

Timberland originated $100.09 million in loans during the quarter ended September 30, 2025, compared to $81.99 million for the preceding quarter and $48.82 million for the comparable quarter one year ago.  Timberland continues to originate fixed-rate one- to four-family mortgage loans, a portion of which are sold into the secondary market for asset-liability management purposes and to generate non-interest income.  During the current quarter, fixed-rate one- to four-family mortgage loans totaling $9.01 million were sold compared to $6.11 million for the preceding quarter and $5.62 million for the comparable quarter one year ago.

Investment Securities

Timberland’s investment securities and CDs held for investment decreased $14.18 million, or 6%, to $223.18 million at September 30, 2025, from $237.36 million at June 30, 2025. The decrease was primarily due to the maturities of U.S. Treasury Securities and scheduled amortization, and was partially offset by the purchase of additional U.S. government agency mortgaged-backed investment securities and U.S. Treasury investment securities.

Deposits

Total deposits increased $47.16 million, or 3%, during the quarter to $1.72 billion at September 30, 2025, from $1.67 billion at June 30, 2025.  The quarter’s increase consisted of a $25.22 million increase in certificate of deposit account balances, a $24.46 million increase in non-interest deposit account balances and a $10.68 million increase in NOW checking account balances.  These increases were partially offset by a $9.06 million decrease in money market account balances and a $4.15 million decrease in savings account balances.

Borrowings

Total borrowings were $20.00 million at both September 30, 2025 and June 30, 2025.  At September 30, 2025, the weighted average rate on the borrowings was 3.97%.

Shareholders’ Equity and Capital Ratios

Total shareholders’ equity increased $5.95 million, or 2%, to $262.61 million at September 30, 2025, from $256.66 million at June 30, 2025, and increased $17.20 million, or 7%, from $245.41 million at September 30, 2024.  The increase in shareholders’ equity during the quarter was primarily due to net income of $8.45 million, proceeds from stock option exercises of $847,000, and a $477,000 recovery of accumulated other comprehensive loss.  These increases to shareholders’ equity were partially offset by the payment of $2.05 million in dividends to shareholders and the repurchase of 56,562 shares of common stock for $1.89 million (an average price of $33.34 per share).  At September 30, 2025, Timberland had 337,280 shares available to be repurchased in accordance with the terms of its existing stock repurchase plan.

Timberland remains well capitalized with a total risk-based capital ratio of 20.67%, a Tier 1 leverage capital ratio of 12.59%, a tangible common equity to tangible assets ratio (non-GAAP) of 12.38%, and a shareholders’ equity to total assets ratio of 13.05% at September 30, 2025.  Timberland’s held to maturity investment securities were $136.86 million at September 30, 2025, with a net unrealized loss of $4.56 million (pre-tax).  Although not permitted by U.S. Generally Accepted Accounting Principles (“GAAP”), including these unrealized losses in accumulated other comprehensive income (loss) (“AOCI”) would result in a ratio of shareholders’ equity to total assets of 12.89%, compared to 13.05%, as reported.

Timberland’s non-performing assets to total assets ratio was 0.23% at September 30, 2025, compared to 0.21% at June 30, 2025, and 0.20% at September 30, 2024.  Net charge-offs totaled less than $1,000 for the current quarter compared to net recoveries of $1,000 for the preceding quarter and net charge-offs of $12,000 for the comparable quarter one year ago.  During the current quarter, provisions for credit losses of $213,000 on loans and $18,000 unfunded commitments were made, which was partially offset by a $10,000 recapture of credit losses on investment securities.  The allowance for credit losses (“ACL”) for loans as a percentage of loans receivable was 1.22% at September 30, 2025, compared to 1.23% at June 30, 2025, and 1.21% one year ago.

Total delinquent loans (past due 30 days or more) and non-accrual loans decreased $515,000 or 8%, to $5.66 million at September 30, 2025, from $6.18 million at June 30, 2025, and increased $1.18 million, or 26%, from $4.49 million at September 30, 2024.  Non-accrual loans increased $564,000, or 15%, to $4.41 million at September 30, 2025 from $3.84 million at June 30, 2025, and increased $522,000, or 13%, from $3.89 million at September 30, 2024.  The quarterly increase in non-accrual loans was primarily due to one single-family construction loan being placed on non-accrual status.  Loans graded “Substandard” totaled $32.80 million (or 2% of total loans receivable) at September 30, 2025.  (Note: Subsequent to September 30, 2025, the Bank’s largest “Substandard” loan, an $11.55 million land development loan, paid off in full.)
