INGRAM MICRO PROVIDES THIRD QUARTER EARNINGS UPDATE

SANTA ANA, Calif., October 17, 2011 — Ingram Micro Inc. (NYSE: IM), the world’s largest technology distributor and supply-chain services provider, today provided a preliminary update on certain expected financial results for the fiscal third quarter that ended October 1, 2011.

Worldwide sales for the third quarter are expected to be approximately $8.9 billion, in-line with the company’s expectations and growing modestly in local currencies compared with both the second quarter of this year and the third quarter of the prior year.

Third-quarter earnings per share are expected to range from a non-GAAP $0.32 to $0.34 per share (or $0.13 to $0.15 on a GAAP basis, which includes the non-recurring charges described below). Earnings per share were impacted by the following factors:

These factors dampened gross margins and operating leverage, which brought earnings per share below the company’s expectations for the quarter, explained Gregory Spierkel, chief executive officer.

“Demand in our key customer segment, which serves small and medium businesses, remained relatively solid in most parts of the world,” Spierkel said. “Most areas of our business are performing well, outside of the recovery efforts in Australia and the effects of the European economy. We look forward to providing greater detail on our operations and results during our conference call with investors on October 27.”

Expected Third-Quarter Charges

The company also expects to record third-quarter charges totaling approximately $29 million, or $0.19 per diluted share, consisting of: a non-cash valuation allowance of approximately $25 million recorded against the company’s deferred tax assets in Brazil, driven by the continuing losses generated in that business unit; and, a charge of approximately $4 million after tax related to the termination of the company’s interest rate swap associated with the repayment of its $250 million term loan, which was replaced by a more flexible $750 million revolver in September.

Preliminary Nature of Results

The company has not yet finalized financial results for the 2011 third quarter ended October 1, 2011. The preliminary estimated financial results described in this release are unaudited and subject to revision pending the completion of the accounting and financial reporting processes necessary to complete the financial closing procedures and financial statements for the fiscal third quarter ended October 1, 2011.

Full financial results will be reported on Thursday, October 27, 2011, after the market close followed by a conference call with executive management at 5 p.m. ET (2 p.m. PT).
