On June 25, 2012, GT Advanced Technologies Inc. (the "Company"), its U.S. operating subsidiary (the "U.S. Borrower") and its Hong Kong subsidiary (the "Hong Kong Borrower") requested and received approval for increases in the term loan for the U.S. Borrower in an aggregate amount equal to $5 million (the "Incremental Term Loan") pursuant to that certain credit agreement (the "Credit Agreement"), by and among the Company, the U.S. Borrower, the Hong Kong Borrower, each lender from time to time party thereto and Bank of America, N.A., as administrative agent, Swing Line Lender and L/C Issuer ("Bank of America") that was entered into on January 31, 2012.

As a result of the Incremental Term Loan, as well as additional incremental term loans entered into between June 15, 2012 and June 21, 2012 in an aggregate amount of $65 million (such additional incremental term loans were previously reported on a Current Report on Form 8-K on June 21, 2012), the aggregate term loan under the Credit Agreement was increased from $75 million to $145 million, all of which was borrowed by the U.S. Borrower.

All of the material terms and conditions related to the Incremental Term Loan were identical to the terms and conditions that apply to the existing term loan issued on January 31, 2012 under the Credit Agreement, including the final maturity date of January 30, 2016 and the interest rate, which in each case is equal to, at the option of the U.S. Borrower, Bank of America's prime rate plus a margin of 2.00% or LIBOR plus a margin of 3.00%. The Incremental Term Loan amortizes at the same times, and in proportional amounts, as the existing term facility, commencing with the first amortization payment under both term facilities being made in June 2012.

The Incremental Term Loan was entered into pursuant to a Supplement No. 3 (the "Supplement") to the Joinder to the Credit Agreement between the Company, the U.S. Borrower, the Hong Kong Borrower, the lenders party thereto and Bank of America, as administrative agent. Such Supplement was dated as of June 25, 2012.

The foregoing descriptions of the Supplement are not meant to be exhaustive and are qualified in their entirety by the Credit Agreement (previously filed on a Current Report on Form 8-K on February 3, 2012) and the Joinder (previously filed on a Current Report on Form 8-K on June 21, 2012), a copy of which is attached hereto as Exhibit 10.1 and is incorporated herein by reference.

The information set forth in Item 1.01 above is hereby incorporated by reference into this Item 2.03.
