EXHIBIT 99.4 IBT BANCORP INC. AND THE FARWELL STATE SAVINGS BANK UNAUDITED COMBINED PRO FORMA FINANCIAL INFORMATION IBT BANCORP, INC. AND FARWELL STATE SAVINGS BANK UNAUDITED PRO FORMA FINANCIAL INFORMATION BASIS OF PRESENTATION The following unaudited pro forma combined balance sheet and income statements give effect to the merger. This pro forma financial information is based on the historical consolidated financial statements of IBT Bancorp Inc. (IBT) and The Farwell State Savings Bank (Farwell) under the assumptions, and including the adjustments, set forth in the accompanying notes to unaudited pro forma combined financial statements. The unaudited pro forma consolidated combined balance sheet present combined financial information as of September 30, 2006, and the unaudited pro forma consolidated combined statements of income presents combined financial information for the nine month period ended September 30, 2006, and for the year ended December 31, 2005. The unaudited pro forma consolidated combined balance sheet assumes the merger was consummated on September 30, 2006, and the unaudited pro forma consolidated combined statements of income give effect to the merger as if the merger occurred at the beginning of each period covered by such pro forma statements of income. Pro forma per share amounts are based on total merger consideration of $145 per share of Farwell common stock. IBT will account for the acquisition under the purchase method of accounting. Accordingly, IBT will establish a new basis for Farwell's assets and liabilities based upon the fair values thereof and the IBT purchase price, including direct and incremental costs of the acquisition. The purchase accounting adjustments made in connection with the development of the unaudited combined pro forma financial statements are preliminary and have been made solely for the purpose of developing such pro forma financial information and are based on the assumptions described in the notes thereto. The unaudited pro forma consolidated combined financial statements reflect the restructuring and other merger related expenses disclosed in the notes to such statements but do not reflect anticipated cost savings that may be achieved with respect to the combined businesses nor any adjustment to expenses for any future operating changes. IBT may incur integration related expenses not reflected in the pro forma financial statements, such as operational realignment. As a result of this and other factors, the pro forma consolidated combined financial condition and results of operations of IBT as of and after the effective time of the merger may not be indicative of the results that actually would have occurred if the merger had been in effect during the periods presented nor of the results that may be attained in the future. IBT is unaware of events that would require a material change to the preliminary purchase price allocation. IBT BANCORP, INC.
