ADAPTEC ANNOUNCES PRELIMINARY REVENUE AND EARNINGS FOR THE THIRD QUARTER
OF FISCAL 2007

MILPITAS, Calif. - January 9, 2007 - Adaptec, Inc. (NASDAQ: ADPT), a global leader in storage solutions, today reported preliminary results for the third quarter of fiscal 2007 that are lower than the ranges projected during the Company's second quarter earnings conference call on October 30, 2006.

The Company expects revenue of approximately $60.0 million to $61.0 million and a loss per share from continuing operations, computed on a Generally Accepted Accounting Principles (GAAP) basis, of approximately $(0.08) to $(0.05) for the third quarter of fiscal 2007. The Company expects a non-GAAP loss per share from continuing operations of approximately $(0.05) to $(0.02) for the third quarter of fiscal 2007. GAAP loss per share differs from non-GAAP loss per share in that the GAAP loss per share includes approximately $1.5 million of amortization expense and approximately $2.5 million related to FAS 123(R) compensation expense.

The Company primarily attributed its lower revenue expectations for the third quarter of fiscal 2007 to a significant decrease in actual revenue versus forecasts from its largest Original Equipment Manufacturer (OEM) customer, IBM, which had accounted for approximately 30 percent of total revenue over the past several quarters.

Adaptec noted that the financial statements for the third quarter of its fiscal year 2007 have not been completed. The revenue and earnings described in this release are based on management's best estimates and remain subject to changes and refinements that could occur during the quarter-end close process. The Company has included a normalized tax expense of $0.5 million in both the GAAP and non-GAAP estimations, as the final GAAP tax impact is still being calculated and could differ significantly from this estimate.

Adaptec will announce its final third quarter fiscal 2007 financial and operating results during its regularly scheduled quarterly conference call on January 30, 2007 at 1:45 p.m. Pacific Standard Time (PST). Adaptec Chief Executive Officer, S. `Sundi' Sundaresh and Chief Financial Officer, Chris O'Meara will host the call. A question-and-answer session will follow their presentations.
