Tyson Foods, Inc. (NYSE: TSN) announced yesterday it is commencing a cash tender offer to purchase up to 50.1% of the outstanding shares of common stock of IBP, inc. (NYSE: IBP) for $26.00 per share.

John Tyson, Tyson’s Chairman, President and CEO, said, “We have begun the due diligence process, and at this point have identified up to $100 million in annual synergies, and expect to achieve half of that in the first year. Obviously, this adds to the significant accretion that we expect to realize on both a GAAP and cash basis, as we announced in our proposal last week.”

Tyson added, “We believe IBP has an excellent strategy to drive change through convenience, value added, and retail case ready products. We firmly believe that with our experience in these areas we can accelerate their progress and insure their success. This will allow us significant opportunity for top line growth and margin expansion as we go forward.

“Additionally, Tyson’s leadership position in foodservice makes us uniquely qualified to capitalize on the scale IBP has created with their Foodbrands group. The synergies between our value added business and our prepared foods subsidiaries, when coupled with Foodbrands broad offerings are significant. We are excited about the possibilities.”

The offer is part of a proposal by Tyson to acquire all of the outstanding shares of IBP in a negotiated transaction. Tyson has delivered to IBP a form of merger agreement and intends to seek to negotiate with IBP with respect to the proposed acquisition. The merger agreement contemplates a second step merger in which all remaining IBP shareholders would receive in exchange for their shares, shares of Tyson Class A common stock having a value of $26.00 per share, if during the relevant pricing period before the merger, the average per share price of Tyson’s Class A common stock is at least $12.60 and no more than $15.40.

A Special Committee of independent directors of IBP is currently evaluating various acquisition proposals, including Tyson’s. As part of the process, Tyson entered into a confidentiality agreement with the Company that permits Tyson to make the offer. Tyson is commencing the offer at this time in order to begin to clear regulatory hurdles and to give IBP shareholders the opportunity, when Tyson and IBP enter into a merger agreement as proposed by Tyson, to quickly receive the cash consideration offered by Tyson.

The tender offer and withdrawal rights are scheduled to expire at 12:00 midnight, Eastern Standard Time, on Wednesday, January 10, 2001, unless extended.

The tender offer is conditioned upon, among other things: (1) there being validly tendered and not withdrawn prior to the expiration of the offer a number of shares of IBP common stock representing, together with the shares owned by Tyson, at least 50.1% of the total number of shares outstanding; (2) Tyson being satisfied, in its sole discretion, that the existing Agreement and Plan of Merger dated October 1, 2000 among the IPB, Rawhide Holdings Corporation and Rawhide Acquisition Corporation has been terminated; (3) the execution by Tyson of a definitive merger agreement with IBP, in form satisfactory to Tyson in its sole discretion; (4) Tyson being satisfied that the provisions of section 203 of the Delaware General Corporation Law do not apply to or otherwise restrict Tyson’s tender offer and the proposed merger; and (5) any waiting periods under applicable antitrust laws having expired or been terminated. The Offer is also subject to other customary conditions, but is not conditioned upon financing.

Merrill Lynch & Co. is acting as Dealer Manager for the tender offer and MacKenzie Partners , Inc. is acting as Information Agent.
