HOQUIAM, WA – April 24, 2018 - Timberland Bancorp, Inc. (NASDAQ: TSBK) ("Timberland" or "the Company") today reported net income increased 36% to $4.27 million, or $0.57 per diluted common share, for its second fiscal quarter ended March 31, 2018, from $3.13 million, or $0.42 per diluted common share, for the quarter ended March 31, 2017, and increased 18% from $3.61 million, or $0.48 per diluted common share, for the preceding quarter ended December 31, 2017.

For the first six months of fiscal 2018, Timberland earned $7.88 million, or $1.05 per diluted common share, an increase in net income of 26% and an increase in earnings per diluted common share ("EPS") of 22% from $6.28 million, or $0.86 per diluted common share, reported for the first six months of fiscal 2017.

Timberland's Board of Directors also declared a quarterly cash dividend to shareholders of $0.13 per common share and a special one-time dividend of $0.10 per common share payable on May 25, 2018, to shareholders of record on May 11, 2018.

"We have continued to emphasize our operations along Western Washington's economically important I-5 corridor and, correspondingly, have continued to significantly and consistently improve the Company's financial metrics year over year," said Michael Sand, President and CEO. "We have expended considerable efforts developing and profitably growing our franchise within our primary markets and have specifically focused on increasing core deposits. Particular attention has been devoted to growing transaction account balances, and we have successfully expanded this segment of our funding base. Strong economic conditions persist in the northwest markets we serve, and we see ample opportunity for the continued profitable growth of our franchise."

"Additionally, based on a number of factors, including the Company's sustained strong financial performance, Timberland's Board of Directors voted to pay a one-time special dividend of $0.10 per share in addition to the regular $0.13 per share quarterly dividend. This special dividend marks the third special dividend the Company has paid in the past three years."

Operating Results

Operating revenue (net interest income before the recapture of loan losses, plus non-interest income excluding gains or losses on the sale of investment securities and other than temporary impairment ("OTTI") charges (recoveries) on investment securities) increased 12% for the current quarter to $12.69 million from $11.30 million for the comparable quarter one year ago and increased 1% from $12.55 million for the preceding quarter. Operating revenue increased 11% to $25.24 million for the first six months of fiscal 2018 from $22.83 million for the comparable period one year ago.

Net interest income for the current quarter increased 14% to $9.62 million from $8.45 million for the comparable quarter one year ago and increased 2% from $9.43 million for the preceding quarter. The increase in net interest income compared to the preceding quarter was primarily due to an increase in average total interest-earning assets and an increase in the yield earned on average total interest-earning assets and was partially offset by an increase in the cost of interest-bearing deposits. The increase in net interest income relative to the comparable quarter one year ago was also partially due to paying off FHLB borrowings and eliminating the associated interest expense. For the first six months of fiscal 2018 net interest income increased 14% to $19.06 million from $16.76 million for the first six months of fiscal 2017.

The net interest margin ("NIM") for the current quarter improved to 4.19% from 3.88% for the comparable quarter one year ago and matched the 4.19% recorded for the preceding quarter. The NIM for the current quarter was increased by approximately six basis points due to the collection of a $134,000 loan prepayment penalty and the collection of $2,000 of non-accrual interest. The NIM for the comparable quarter one year ago was increased by approximately nine basis points due to the collection of $204,000 of non-accrual interest and the NIM for the preceding quarter was increased by approximately two basis points due to the collection of $45,000 of non-accrual interest. Timberland's net interest margin for the first six months of fiscal 2018 improved to 4.19% from 3.90% for the first six months of fiscal 2017.

Non-interest income increased 8% to $3.08 million for the current quarter from $2.85 million for the comparable quarter one year ago and decreased 2% from $3.14 million for the preceding quarter. The decreased non-interest income for the current quarter compared to the preceding quarter was primarily due to a decrease in service charges on deposits and a decrease in gain on sales of loans, which was partially offset by an increase in ATM and debit card interchange transaction fees. Fiscal year-to-date non-interest income increased 2% to $6.22 million from $6.07 million for the first six months of fiscal 2017.

Total operating expenses for the current quarter increased 5% to $7.22 million from $6.86 million for the comparable quarter one year ago and increased 1% from $7.18 million for the preceding quarter. The increased expenses for the current quarter compared to the preceding quarter were primarily due to an increase in salaries and employee benefits and smaller increases in several other categories. These increases were partially offset by a $113,000 gain on the sale of excess land. The efficiency ratio for the current quarter improved to 56.83% compared to 57.08% for the preceding quarter and 60.67% for the comparable quarter one year ago. Fiscal year-to-date operating expenses increased 5% to $14.40 million from $13.67 million for the first six months of fiscal 2017. The efficiency ratio improved for the first six months of fiscal 2018 to 56.96% from 59.86% for the first six months of fiscal 2017.

The provision for income taxes decreased $565,000 to $1.22 million from $1.78 million for the preceding quarter and was impacted by the Tax Cuts and Jobs Act Legislation which was signed into law on December 22, 2017. As a result of the new legislation (which decreases the federal corporate income tax rate to 21.0% from 35.0%), Timberland recorded a one-time income tax expense of $548,000 in conjunction with writing down its net deferred tax asset ("DTA") during the quarter ended December 31, 2017. Since Timberland is a September 30^th fiscal year-end corporation, it will use a blended tax rate of 24.5% for the fiscal year ending September 30, 2018, and a 21.0% rate thereafter. Timberland's effective tax rate for the quarter ended March 31, 2018, was 22.2%.

Balance Sheet Management

Total assets increased $7.31 million, or 1%, to $1.00 billion at March 31, 2018, from $993.90 million at December 31, 2017. The increase was primarily due to a $3.87 million increase in net loans receivable and loans held for sale, and a $3.20 million increase in total cash and cash equivalents. These increases were primarily funded by increased deposits.

Liquidity, as measured by the sum of cash and cash equivalents, CDs held for investment and available for sale investment securities, was 25.3% of total liabilities at March 31, 2018, compared to 25.1% at December 31, 2017, and 24.0% one year ago.

Net loans receivable increased $3.30 million, or 1%, to $708.57 million at March 31, 2018, from $705.27 million at December 31, 2017. The increase was primarily due to an $8.76 million increase in commercial real estate loans, a $3.62 million increase in speculative one- to four-family loans, a $3.17 million increase in commercial construction loans, a $2.95 million increase in land development loans, a $1.34 million decrease in the undisbursed portion of construction loans in process and smaller increases in several other categories. These increases were partially offset by a $6.21 million decrease in multi-family loans, a $4.14 million decrease in one- to four-family construction loans, a $4.11 million decrease in one- to four-family mortgage loans and smaller decreases in several other categories.

Timberland originated $78.99 million in loans during the quarter ended March 31, 2018, compared to $79.50 million for the comparable quarter one year ago and $82.51 million for the preceding quarter. Timberland continues to sell fixed-rate one- to four-family mortgage loans into the secondary market for asset-liability management purposes and to generate non-interest income. Timberland also (on a much smaller volume) periodically sells the guaranteed portion of U.S. Small Business Administration ("SBA") loans. During the second quarter of fiscal 2018 fixed-rate one- to four-family mortgage loans and SBA loans totaling $15.31 million were sold compared to $15.01 million for the comparable quarter one year ago and $15.91 million for the preceding quarter.

Timberland's investment securities and other investments increased $965,000, or 9%, to $12.26 million at March 31, 2018, from $11.30 million at December 31, 2017, primarily due to the purchase of a $1.11 million agency investment security.

Total deposits	$	880,411		100	%	$	876,074		100	%	$	808,852		100	%

Total deposits increased $4.34 million, or 1%, to $880.41 million at March 31, 2018, from $876.07 million at December 31, 2017. This increase was primarily due to a $13.19 million increase in non-interest-bearing demand account balances, an $8.65 million increase in NOW checking account balances, a $5.09 million increase in savings account balances and a $4.65 million increase in certificates of deposit account balances. These increases were partially offset by a $25.82 million decrease in money market account balances. The decrease in money market account balances was primarily due to a commercial customer withdrawing funds in January 2018 that were initially deposited in December 2017.

Shareholders' Equity

Total shareholders' equity increased $3.73 million to $117.84 million at March 31, 2018, from $114.11 million at December 31, 2017. The increase in shareholders' equity was primarily due to net income of $4.27 million for the quarter, which was partially offset by dividend payments to shareholders of $959,000.

Capital Ratios and Asset Quality

Timberland remains well capitalized with a total risk-based capital ratio of 18.01% and a Tier 1 leverage capital ratio of 11.66% at March 31, 2018.

No provision for loan losses was made for the quarters ended March 31, 2018, and December 31, 2017. Timberland recorded a $250,000 loan loss reserve recapture during the comparable quarter one year ago. Net charge-offs totaled $21,000 for the current quarter compared to a net recovery of $12,000 for the preceding quarter and net charge-offs of $3,000 for the comparable quarter one year ago. The allowance for loan losses was 1.33% of loans receivable at March 31, 2018, compared to 1.34% at December 31, 2017, and 1.40% at March 31, 2017.

Total delinquent loans (past due 30 days or more) and non-accrual loans increased 5% to $3.29 million at March 31, 2018, from $3.12 million at December 31, 2017, and increased 23% from $2.66 million one year ago. Non-accrual loans decreased 9% to $1.93 million at March 31, 2018, from $2.11 million at December 31, 2017, and increased 2% from $1.89 million one year ago.

Non-GAAP Financial Measures

In addition to results presented in accordance with generally accepted accounting principles ("GAAP"), this press release contains certain non-GAAP financial measures. Timberland believes that certain non-GAAP financial measures provide investors with information useful in understanding the Company's financial performance; however, readers of this report are urged to review these non-GAAP financial measures in conjunction with GAAP results as reported.

Financial measures that exclude intangible assets are non-GAAP measures. To provide investors with a broader understanding of capital adequacy, Timberland provides non-GAAP financial measures for tangible common equity, along with the GAAP measure. Tangible common equity is calculated as shareholders' equity less goodwill. In addition, tangible assets equal total assets less goodwill.
