Exhibit 99.4 UNAUDITED PRO FORMA FINANCIAL INFORMATION CADENCE AND AMBIT UNAUDITED PRO FORMA FINANCIAL INFORMATION On September 30, 1998, Cadence Design Systems, Inc. ("Cadence") acquired Ambit Design Systems, Inc. ("Ambit"), a privately held California corporation that specializes in developing, manufacturing and marketing specialized Electronic Design Automation (EDA) application software products. The acquisition was accounted for as a purchase. The following unaudited pro forma combined financial statements give effect to the acquisition and should be read in conjunction with the historical financial statements and related notes thereto for both Cadence and Ambit. The unaudited pro forma condensed combined statements of operations for the fiscal year ended January 3, 1998 and the nine-month period ended October 3, 1998 give effect to the acquisition as if the acquisition was completed at the beginning of each period, and combines Cadence's and Ambit's statements of operations for each company's respective period. The required pro forma balance sheet with respect to the acquired business is incorporated by reference to Cadence's Quarterly Report on Form 10-Q for the period ended October 3, 1998 filed with the Commission on November 16, 1998. The pro forma combined results for the nine-month period ended October 3, 1998 excludes acquisition-related charges of $214.4 million for purchased in-process technology related to Ambit. This method of combining historical financial statements for the preparation of the pro forma condensed combined financial statements is for presentation only. Actual statements of operations of the companies will be combined from the acquisition date with no retroactive restatements. The unaudited pro forma condensed combined financial statements are presented for illustrative purposes only and are not necessarily indicative of the combined financial position or combined results of operations of future periods or the results that actually would have resulted had the acquisition occurred on the dates indicated.

CADENCE DESIGN SYSTEMS, INC. AND AMBIT DESIGN SYSTEMS, INC. NOTES TO THE PRO FORMA CONDENSED COMBINED STATEMENTS OF OPERATIONS (UNAUDITED) BASIS OF PRESENTATION The pro forma condensed combined financial statements included herein have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These pro forma condensed combined financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended January 3, 1998 and the Quarterly Report on Form 10-Q for the quarter ended October 3, 1998. The preparation of pro forma condensed combined financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the pro forma condensed combined financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. PRO FORMA ADJUSTMENTS Certain pro forma adjustments have been made to the accompanying pro forma condensed combined Statements of Operations as described below: a) Reflects amortization of goodwill and identified intangible assets for nine month period ended October 3, 1998 ($5.2 million per year for 7 years). b) Reflects amortization of goodwill and identified intangible assets for twelve month period ended January 3, 1998 ($5.2 million per year for 7 years). c) Reflects tax benefit at the statutory rate of 40% relating to the pro forma adjustments. PURCHASE PRICE The purchase price for the acquisition of Ambit is computed as follows (in thousands): Cash payment to Ambit Shareholders $ 252,990 Cadence ownership prior to acquisition 2,000 -------------- Total purchase price $ 254,990 -------------- -------------- IN-PROCESS TECHNOLOGY The acquisition of Ambit was accounted for as a purchase, allocating the purchase price based upon the estimated fair value of the assets acquired and the liabilities assumed. In connection with the acquisition, net intangibles of $250.9 million were acquired. Management estimates that $214.4 million of the purchased intangibles was purchased in-process technology that had not yet reached technological feasibility and has no alternative future use. This amount was expensed in the period ended October 3, 1998 but is excluded from the pro forma condensed combined statement of operations for that period included herein. The value assigned to purchased in-process technology, based on a valuation prepared by a third-party appraisal company, was determined by identifying research projects in areas for which technological feasibility has not been established. The remaining intangible assets of $36.5 million were assigned to goodwill and identified intangible assets and will be amortized on a straight-line basis over their estimated useful lives of seven years. Management believes that the unamortized balance is recoverable through future operating results. If these projects are not successfully developed, business, operating results, and financial condition of the Company may be adversely affected. Additionally, the value of the other intangible assets acquired may become impaired.
