PART III — NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

Altera Corporation (the “Company”) plans to file its Quarterly Report on Form 10-Q for the quarter ended June 30, 2006 as soon as practicable, but does not expect that it will be filed on or before the fifth calendar day following the required filing date as prescribed in Rule 12b-25.

As previously announced, the Company’s board of directors has established a special committee comprised of independent directors to conduct an internal review of the Company’s historical stock option practices and related accounting treatment. At this time, the special committee has not completed its work nor reached final conclusions and is continuing its review. Also as previously announced, the special committee has reached a preliminary conclusion that the actual measurement dates for certain past stock option grants differed from the recorded grant dates for such awards. As a result, the Company expects to record additional non-cash charges for stock-based compensation expense in prior periods. The Company believes that these charges are material, and accordingly, the Company expects to restate its financial statements for the fiscal years ended 1996 through 2005 to reflect these additional charges, although the Company does not anticipate that the charge for fiscal year 2005 will be material. The Company is also currently evaluating the impact of the potential restatement on its report on internal control over financial reporting, which may result in the determination that a material weakness exists. The Company intends to file any necessary restatements, its Quarterly Report on Form 10-Q for the quarter ended March 31, 2006 and its Quarterly Report on Form 10-Q for the quarter ended June 30, 2006 as soon as possible following the completion of the special committee’s review.

This Form 12b-25 contains forward-looking statements concerning the Company’s expected restatement of its historical financial statements and the Company’s review of its historical stock option practices and related accounting treatment. There can be no assurance concerning the outcome of the restatements or the conclusion of the special committee’s review. Important factors that could cause actual results to differ materially include the final determinations of the special committee concerning matters relating to the Company’s stock option grants and other actions that may be taken or required as a result of the special committee’s review. Forward-looking statements are made as of the date of this filing, and, except as required by law, the Company does not undertake an obligation to update its forward-looking statements to reflect future events or circumstances.
