Filing under Rule 425 under the Securities Act of 1933 and deemed filed under Rules 14d-2 and 14a-12 of the Securities Exchange Act of 1934 Filing by: Carnival Corporation Subject Company: P&O Princess Cruises plc. SEC File No. of Princess: 001-15136 NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION IN OR INTO AUSTRALIA, CANADA, OR JAPAN 29 OCTOBER 2002 CARNIVAL CORPORATION - -------------------------------------------------------------------------------- LETTER TO ALL CARNIVAL CORPORATION EMPLOYEES COPIES TO: Carnival Corporation Board of Directors Pam Conover Bob Dickinson Pier Foschi Kirk Lanterman FROM: Micky Arison Howard S. Frank DATE: October 29, 2002 SUBJECT: Proposed Transaction With P&O Princess ================================================================================ By now, many of you have seen the Carnival Corporation and the P&O Princess (POC) announcements, and the many newspaper articles which followed, concerning a possible transaction between our two companies. If we are successful in completing the transaction with POC, Carnival Corporation will become one of the largest leisure companies in the world. The Carnival group would have 65 ships in the combined fleet, with approximately 94,000 berths, and would carry close to 5 million guests worldwide. The group would also have 20 new ships under contract for delivery over the next four years, which will add another 46,000 berths to the combined fleet. Given the substantial increase in our fleet over the next four years, our combined employee base of 53,000 would expand substantially, providing significant opportunities for all employees, including those presently working at POC. Because our offer has still not been approved by the POC board, we have not been in a position to have any discussions with POC management about how the combined group will operate. But, as you know, the Carnival Corporation philosophy of operating our cruise businesses has been on a decentralized basis with each of our cruise brands given considerable freedom in running their day-to-day business. It's anticipated that this organizational model would also carry over to the various POC cruise brands. We will also try to identify synergies which will mainly focus on ways to reduce costs, principally through the sharing of best practices, and taking advantage of greater economies of scale.Although newspaper articles have implied that the transaction is likely to be concluded, we still have several additional hurdles to overcome. The first of these hurdles would be the POC Board of Directors recommending our offer. We are hopeful that this will occur in January 2003. Once the POC board recommends the offer, we will need to gain the approval of 75% of the POC shares voting at a POC shareholder meeting in order to approve the transaction; such vote is expected to occur in February 2003. And, lastly, there is still the possibility that another competitive offer can be made by a third party company to acquire POC, which would compete with our offer. So, you can see, there is still considerable additional work to be done to conclude the transaction. We thank all of our employees for your continuing support through this almost yearlong saga. It should be over soon. Good luck and best wishes to all of you. /s/ Micky Arison /s/ Howard Frank CARNIVAL PLANS TO FILE A REGISTRATION STATEMENT ON FORM S-4, A PROXY STATEMENT ON SCHEDULE 14A AND A STATEMENT ON SCHEDULE TO WITH THE US SECURITIES AND EXCHANGE COMMISSION IN CONNECTION WITH COMMENCEMENT OF ITS PROPOSAL TO ACQUIRE P&O PRINCESS CRUISES PLC.
