Exhibit 99.1

IHOP CORP. DETAILS STRATEGIC FINANCIAL DECISIONS

GLENDALE, Calif., March 24, 2003—IHOP Corp. (NYSE: IHP) today announced that it has reached several strategic financial decisions and adopted a plan designed to distribute cash to shareholders. The Company's new operating model is expected to begin generating substantial positive free cash flows commencing in 2004. In recognition of the Company's reduced need for capital and anticipated improved cash generation, the Board of Directors declared its first quarterly cash dividend of $0.25 per common share and indicated its intent to pay a recurring quarterly dividend going forward. The dividend will be payable May 19, 2003 to shareholders of record as of May 1, 2003. Future dividend declarations will be made at the discretion of the Board of Directors and will be based on such factors as the Company's earnings, financial condition, cash requirements, future prospects and other factors.

        Julia A. Stewart, IHOP Corp. President and Chief Executive Officer, said, "We have taken into consideration what is right for the business and our shareholders. We believe that the implementation of regular quarterly dividend payments is the most viable and attractive option we have today with regard to returning cash to shareholders."

        After a review of its strategic alternatives, the Company has decided that implementing a recurring quarterly dividend and pursuing its previously announced share repurchase program are the most cost-effective and beneficial ways to return cash to shareholders. The Company has reviewed and considered a sale and monetization of approximately $200 million in receivables with a distribution of the proceeds to its shareholders. Management and the Board have determined that these alternatives are not financially attractive due to associated high transaction costs and insufficient returns for the Company and its shareholders.

        IHOP also reiterated its 2.6 million share repurchase authorization and indicated that it continues to monitor the market for its stock and intends to effect purchases on the open market and in block transactions whenever it deems appropriate. Additionally, IHOP reaffirmed its EPS guidance for fiscal 2003 of $1.55 to $1.70 per diluted share.

Sale or Monetization of Receivables

        The Company's management and Board of Directors reviewed the potential sale of its franchisee note and equipment lease receivables and determined, for various reasons, that a sale is not a financially attractive alternative for the Company. The amounts suggested by third parties that they would be willing to pay for the receivables were deemed by management to be inadequate. In addition, upon a sale of the receivables, IHOP might incur an immediate significant tax liability. The sale of these receivables might also cause the Company to violate covenants under existing debt instruments. In order to sell the receivables IHOP would be required to renegotiate or prepay these debt instruments and incur substantial prepayment penalties. The combination of the inadequate suggested values and tax liability would yield net proceeds from a sale insufficient to fund the resulting debt repayment obligation let alone allow for proceeds for a distribution to shareholders.

        Stewart concluded, "The sale of our receivables would have been subject to a significant discount, immediate tax liability and penalties under existing debt instruments. The economics of such a transaction provide negligible upside to IHOP and our shareholders and is not a feasible vehicle to return cash to shareholders."

        IHOP also researched the possibility of selling its direct financing receivables, or otherwise monetizing its rental income, and determined that such a sale was not practical. The Company's direct financing receivables and rental income are encumbered by capital and operating lease obligations. In order to effect a sale, IHOP would need to obtain, in many cases, consents from leaseholders and lessees and, in some cases, modifications to the underlying leases. IHOP's management determined that

obtaining such consents and modifications would be cumbersome, time consuming and expensive and provide no guarantee of success.

        In lieu of a sale of receivables, management and the Board also explored raising incremental borrowings to fund a large, one time, distribution to shareholders. This included a possible securitization of its receivables, as well as other forms of debt secured by such receivables. While the Company has determined that it has the ability to raise additional borrowings, it decided that it would not be prudent, at this time, to incur substantial incremental debt.

New Segment Reporting

        The Company also announced that effective with the publication of its first quarter 2003 10Q report, it will report its results across four key segments of its business. This new segment reporting should be more transparent and help investors to better understand the Company's business operations and results in light of its new operating model. The makeup of the four segments—Franchise Operations, Financing Operations, Rental Operations and Company Operations—will be discussed in detail on the Investor Conference Call scheduled for Monday, March 24, 2003.
