These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of October 3, 2006 and September 30, 2006 and 2005, and the changes in its net assets available for benefits for the period ended October 3, 2006 and for the year ended September 30, 2006, in conformity with accounting principles generally accepted in the United States of America. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules as of September 30, 2006, are presented for the purpose of additional analysis and are not a required part of the basic financial statements, but are supplementary information required by the United States Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. These supplemental schedules are the responsibility of the Plan's management. The supplemental schedules have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated, in all material respects, in relation to the basic financial statements taken as a whole. As discussed in Note 6 to the financial statements, the Board of Directors of Timberland Bank, the Plan's sponsor, voted on September 26, 2006, to merge the Plan into the Timberland Bank Employee Stock Ownership Plan effective October 1, 2006. All plan assets were transferred to Timberland Bank Employee Stock Ownership and 401(k) Plan on October 3, 2006. /s/McGladrey & Pullen, LLP Tacoma, Washington March 16, 2007 Financial Statements Statements of Net Assets Available for Benefits ------------------------------------------------------------------------------ Timberland Bank 401(k) Profit Sharing Plan October 3, 2006, September 30, 2006 and 2005 October 3, September 30, September 30, 2006 2006 2005 Assets Investments (participant-directed) $ - - $ 10,533,494 $ 6,882,117 Employer contributions receivable - - - - 640,660 Employee receivable - - - - 305 Cash - - 12,814 10,696 Accrued income - - 2,927 1,667 Total assets - - 10,549,235 7,535,445 Liabilities - - - - - - Net assets available for benefits $ - - $ 10,549,235 $ 7,535,445 See notes to financial statements. 2 Statement of Changes in Net Assets Available for Benefits ------------------------------------------------------------------------------ Timberland Bank 401(k) Profit Sharing Plan Period Ended October 3, 2006 and Year Ended September 30, 2006 October 3, September 30, 2006 2006 Additions to Net Assets Investment income: Net appreciation (depreciation) in fair value of investments ($15,276) $ 2,292,733 Dividends - - 147,403 Total investment income (loss) (15,276) 2,440,136 Contributions: Employer - - 558,417 Participant - - 426,691 Total contributions - - 985,108 Total additions (15,276) 3,425,244 Deductions from Net Assets Benefits paid - - 380,146 Administrative expenses 2,661 31,308 Total deductions 2,661 411,454 Net increase (decrease) before transfer of assets to other qualified plan (17,937) 3,013,790 Transfer to Timberland Bank Employee Stock Ownership and 401(k) Plan 10,531,298 - - Net increase (decrease) (10,549,235) 3,013,790 Net Assets Available for Benefits Beginning of period 10,549,235 7,535,445 End of period $ - - $ 10,549,235 See notes to financial statements. 3 Notes to Financial Statements ------------------------------------------------------------------------------ Timberland Bank 401(k) Profit Sharing Plan October 3, 2006, September 30, 2006 and 2005 Note 1 - Plan Description The following description of Timberland Bank 401(k) Profit Sharing Plan (the Plan) provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. General The Plan is a defined contribution plan covering substantially all full-time employees of Timberland Bank (the Company) who have one year of service and are 21 years of age or older. It is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). The Company is the wholly owned subsidiary of Timberland Bancorp, Inc. These financial statements include the year ended September 30, 2006 and the three day period ended October 3, 2006. The Plan elected to defer the filing of its financial statements with its Form 5500 for the short year ended October 3, 2006, as permitted by 29 CFR 2520.104-50, since the following Plan year ended September 30, 2007 is a short year of seven months or less. Accordingly, the Plan has included statements of net assets as of October 3, 2006 and September 30, 2006 and 2005, along with statements of changes in net assets for the period ended October 3, 2006 and year ended September 30, 2006, as required by DOL regulations when such election is made. Contributions and Participant Investment Options The Plan participants may contribute up to the maximum of pretax annual compensation as set by law. Participants may also contribute amounts representing distributions from other qualified defined benefit or defined contribution plans. The Company makes an annual safe harbor contribution of 3 percent of eligible compensation, with additional amounts contributed at the option of its board of directors. For the year ended September 30, 2006, the board of directors authorized a 5 percent profit sharing contribution of total eligible participant compensation in addition to the safe harbor contribution. Participants must direct their salary deferral contributions and their allocated shares of the safe harbor contribution and the employer contribution, if any, into a variety of investment choices, as made available and determined by the Plan administrator, which are more fully described in the Plan's literature. Participant Accounts Each participant's account is credited with the participant's contributions and allocations of: (a) the Company's contributions, (b) Plan earnings, and (c) the forfeitures of terminated participants' nonvested accounts, and charged with an allocation of administrative expenses. Allocations are based on participant earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. (continued) 4 Notes to Financial Statements ------------------------------------------------------------------------------ Timberland Bank 401(k) Profit Sharing Plan October 3, 2006, September 30, 2006 and 2005 Note 1 - Plan Description (concluded) Vesting Participants are immediately vested in all deferral, rollover and safe harbor contributions, plus actual earnings thereon. Vesting in the Company's discretionary contribution portion of accounts, plus earnings thereon, is based on years of credited service. Participants are fully vested after six years of credited service. A participant's accrued benefit derived from employer contributions is also 100% nonforfeitable upon attaining the age of 62, or if the participant's separation from service is a result of death or disability. Payment of Benefits On termination of service, a participant with an accrued benefit of $1,000 or less will receive a lump-sum amount equal to the value of the vested interest in their account. A terminated participant with accrued benefits over $1,000, but less than or equal to $5,000, who does not take a distribution after termination, may have their accrued benefit directly transferred to an Individual Retirement Account (IRA). The distribution date will be the earliest administratively feasible date for participants who attain normal retirement at the age of 62 or early retirement at the age of 55 with 10 years of service. Distributions for participants who do not meet these requirements will be made as soon as administratively feasible in the Plan year following separation of service. A Participant with an accrued benefit in excess of $5,000 may leave the funds in the Plan or elect to receive a lump sum distribution equal to the value of the vested interest in his or her accounts. Forfeited Accounts Forfeited balances of terminated participant nonvested accounts are treated as discretionary contributions for the Plan year in which the forfeitures occur. Forfeitures allocated for the year ended September 30, 2006, totaled $22,012. There are no unallocated forfeitures as of September 30, 2006 or October 3, 2006. Note 2 - Summary of Significant Accounting Policies Basis of Accounting The financial statements of the Plan are prepared under the accrual method of accounting. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and changes therein, and the disclosure of contingent assets and liabilities. Actual results could differ from those estimates. 5 Notes to Financial Statements ------------------------------------------------------------------------------ Timberland Bank 401(k) Profit Sharing Plan October 3, 2006, September 30, 2006 and 2005 Note 2 - Summary of Accounting Policies (concluded) Investment Valuation and Income Recognition The Plan's investments are stated at fair value. Quoted market prices are used to value common stock and mutual funds. Shares of mutual funds are valued at the net asset value of shares held by the Plan at year-end. Purchases and sales of securities are recorded on the trade-date basis. Dividends are recorded on the ex-dividend date. Payment of Benefits Benefits are recorded when paid.

The prototype plan received an opinion letter dated April 8, 2002, from the Internal Revenue Service, which stated that the Plan, as then designed, was in compliance with the applicable requirements of the Internal Revenue Code. The Plan has been amended subsequent to receiving the opinion letter. However, the Plan administrator believes the Plan is designed and operated in compliance with applicable provisions of the Internal Revenue Code. Note 5 - Administration of Plan Assets Certain Plan investments are shares of mutual funds managed by US Bank. US Bank is the trustee, as defined by the Plan; therefore, these transactions qualify as party-in-interest transactions. Fees paid by the Plan for investment management services totaled $31,308 for the year ended September 30, 2006 and $2,661 for the period ended October 3, 2006. Certain administrative functions of the Plan are performed by officers or employees of the Company. No such officers or employees receive compensation from the Plan. Other administrative and management fees of the Plan are paid directly by the Company. Note 6 - Plan Merger Effective October 1, 2006, Timberland Bank 401(k) and Profit Sharing Plan and Timberland Bank Employee Stock Ownership Plan were merged with the surviving plan being the Timberland Bank Employee Stock Ownership Plan. The surviving plan's name was changed to the Timberland Bank Employee Stock Ownership and 401(k) Profit Sharing Plan (KSOP). All plan assets were transferred to Timberland Bank Employee Stock Ownership and 401(k) Plan on October 3, 2006. The KSOP is administered by Pentegra Retirement Services, and the trustee for the plan is HomeFederal Bank. 7 Supplemental Schedules Schedule of Assets (Held at End of Year) ------------------------------------------------------------------------------ Timberland Bank 401(k) Profit Sharing Plan September 30, 2006 EIN: 91-0260220 Plan Number: 001 (a) and (b) (c) (d) (e) Identity of Issue, Description of Investment, Including Cost Current Borrower, Lessor Maturity Date, Rate of Interest, Value or Similar Party Collateral, Par or Maturity Value (pv or mv) ** Timberland Bancorp, Inc.
