Introduction to Pro Forma Condensed Combined Financial Information (Unaudited)

On May 11, 2010, Green Mountain Coffee Roasters, Inc. (“GMCR”) acquired Diedrich Coffee, Inc. (“Diedrich”) for $35 per share of common stock in cash, pursuant to a cash tender offer, for a total purchase price of approximately $313,143,000. The transaction was financed using existing cash and GMCR’s existing credit facility, as increased by an amendment on the acquisition date. Diedrich will be maintained as a wholly-owned subsidiary, with operations integrated into GMCR’s Specialty Coffee Business Unit segment. In addition, on November 13, 2009, GMCR entered into a Share Purchase Agreement to acquire all of Timothy’s Coffees of the World Inc. (“Timothy’s”) issued and outstanding stock for a purchase price of $156,274,000. The accompanying unaudited pro forma condensed combined financial information is based on the historical financial statements of GMCR, Diedrich and Timothy’s. The information attempts to illustrate the effect that GMCR’s acquisition of Diedrich and Timothy’s would have had on GMCR’s financial statements if the transaction had been consummated at earlier dates as described below. This information is hypothetical and does not necessarily reflect the financial performance that would have actually resulted if the acquisition of Diedrich and Timothy’s had been completed on the dates assumed.

The Unaudited Pro Forma Condensed Combined Balance Sheet presents the historical financial position of GMCR as though the Diedrich acquisition was consummated on March 27, 2010, the end of GMCR’s second fiscal quarter. Because the Timothy’s acquisition occurred prior to the balance sheet date there are no pro forma adjustments for this acquisition. The Unaudited Pro Forma Condensed Combined Statements of Operations present the historical results of operations of GMCR for the twenty-six weeks ended March 27, 2010 and the fifty-two weeks ended September 26, 2009. The accompanying Unaudited Pro Forma Condensed Combined Statements of Operations reflect pro forma adjustments for both Diedrich and Timothy’s as though the acquisitions were consummated on September 28, 2008, the beginning of GMCR’s 2009 fiscal year.

GMCR’s historical results as of and for the twenty–six weeks ended March 27, 2010 are derived from GMCR’s unaudited consolidated financial statements included in its Quarterly Report on Form 10-Q for the quarter ended March 27, 2010. GMCR’s historical results for the fifty-two weeks ended September 26, 2009 are derived from GMCR’s audited consolidated financial statements included in its Annual Report on Form 10-K for the fifty-two weeks ended September 26, 2009. The Unaudited Pro Forma Condensed Combined Balance Sheet was prepared using Diedrich’s historical balance sheet as of March 3, 2010. The Unaudited Pro Forma Condensed Combined Statement of Operations for the twenty-six weeks ended March 27, 2010 was prepared using Diedrich’s historical results of operations for the twenty-four weeks ended March 3, 2010 and Timothy’s historical results of operations for the six weeks ended November 12, 2009, the period prior to the acquisition. For the period of November 12, 2009 through March 27, 2010, Timothy’s results of operations are included in GMCR’s historical results. The Unaudited Pro Forma Condensed Combined Statement of Operations for the fifty-two weeks ending September 26, 2009 was prepared using Diedrich historical results of operations for the fifty-two weeks ending September 16, 2009 and Timothy’s historical results of operations for the fifty-two weeks ending July 26, 2009.

The unaudited pro forma condensed combined financial statements have been prepared using the acquisition method of accounting. The allocation of the purchase price to the fair values of the identified tangible and intangible assets acquired and liabilities assumed was based upon an independent valuation and management estimates. The historical financial information has been adjusted to give effect to matters that are (1) directly attributable to the acquisition, (2) factually supportable, and (3) with respect to the statement of operations, expected to have a continuing impact on the operating results of the combined company.

The accompanying unaudited pro forma condensed combined financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto included on GMCR’s 2009 Annual Report on Form 10-K, Quarterly Report on Form 10-Q for the twenty-six weeks ended March 27, 2010, Current Report on Form 8-K for the Timothy’s acquisition filed on November 13, 2009, as amended and; Diedrich’s 2009 Annual Report on Form 10-K, Quarterly Report on Form 10-Q for the twelve-weeks ended December 9, 2009 and Quarterly Report on Form 10-Q for the twelve weeks ended March 3, 2010. GMCR’s management believes that the assumptions used in preparing these unaudited pro forma condensed combined financial statements provide a reasonable basis for presenting all of the significant effects of the acquisitions. These unaudited pro forma condensed combined financial statements presented are for informational purposes only and do not purport to be indicative of the results that would have actually occurred if the acquisitions had been consummated on the dates indicated or of those results that may be achieved in the future. In addition, the allocation of the Diedrich purchase price is preliminary and, accordingly, the purchase accounting adjustments made in the preparation of the unaudited pro forma condensed combined financial statements may be subject to adjustment which could have a material impact on the accompanying unaudited pro forma condensed combined financial statements.

(C) The total purchase price associated with the Diedrich acquisition was $313,143,000 of which approximately $143,643,000 was financed with cash on hand, $29,500,000 from the existing credit facility and $140,000,000 from the Amendment to the Credit Agreement in the form of a term loan.

(D) Represents the elimination of trade accounts receivable and accounts payable for the sale of coffee, brewers and related royalties between GMCR and Diedrich.

(E) Represents the estimated fair value adjustment to Diedrich’s acquired inventory. The Unaudited Pro Forma Condensed Combined Statements of Operations exclude any adjustment to cost of sales for the estimated fair value adjustment due to the non-recurring nature of the adjustment.

(F) Represents a current net tax asset of $1,733,000 and a long-term net tax liability of $30,361,000 calculated as of the date of the Diedrich acquisition. The current net tax asset is primarily related to accrued compensation expenses. The net long-term tax liability is related to the amortization on the intangible assets, which are deductible for book purposes but not for tax, offset by a long-term tax benefit for net operating loss carryforwards.

(G) Represents the estimated fair value adjustment to Diedrich’s acquired fixed assets for a decrease of approximately $1,994,000. In addition, this adjustment reflects the acquisition of certain leased equipment as required by the Agreement and Plan of Merger for approximately $6,509,000.

(H) Reflects estimated fair value of identified intangible assets based upon an independent valuation and management’s estimates as of the date of acquisition, as follows:

(I) Reflects residual of the acquisition price for Diedrich of $313,143,000 over the fair value of the assets acquired and liabilities assumed as of March 27, 2010 as follows:

The final allocation will be based on the fair value of assets acquired and liabilities assumed as of the acquisition date of May 11, 2010.

(J) Reflects the additional borrowing GMCR incurred to finance the acquisition. GMCR incurred $29,500,000 from its existing credit facility and $140,000,000 from the Amendment to the Credit Agreement in the form of a term loan. In addition, this adjustment reflects the elimination of Diedrich’s debt of $3,501,000 that was not assumed in the acquisition.

(R) Reflects the interest that would have been incurred on debt used to finance the acquisition using the rate in effect at the time of acquisition. The rate on the existing credit facility was 1.09% (one-month LIBOR plus 75 basis points) and the rate on the term loan was 2.84% (one-month LIBOR plus 250 basis points). In addition, this adjustment reflects the elimination of interest expense on Diedrich and Timothy’s long-term debt that was not assumed in the acquisitions.

Debt incurred to finance the acquisition that was subject to variable interest rates was $159,000,000 for the twenty-six weeks ended March 27, 2010 and $169,500,000 for the fifty-two weeks ended September 26, 2009. Had interest rates increased by 125 basis points, the effect on net income would have been additional interest expense of $994,000 during the twenty-six weeks ended March 27, 2010 and $2,119,000 during the fifty-two weeks ended September 26, 2009.

(S) Reflects elimination of acquisition related expenses incurred by Diedrich.
