Exhibit 99 FOR IMMEDIATE RELEASE NEWS RELEASE Contact: Glenn P. Muir Susan Schoenhals Executive Vice President and CFO Manager, Investor Relations Hologic, Inc. Hologic, Inc. (781) 999-7300 (781) 999-7377 Hologic Adopts New Shareholder Rights Plan BEDFORD, Mass., (September 26, 2002) -- Hologic, Inc. (NASDAQ: HOLX), a leading provider of women's diagnostic imaging systems and state-of-the-art general digital radiography systems, today announced that its Board of Directors has adopted a new shareholder rights plan. The new shareholder rights plan replaces Hologic's current rights plan when it expires on December 31, 2002. In addition to certain other modifications, the new rights plan uses preferred stock purchase rights rather than common stock purchase rights. To effect the new rights plan, the Board of Directors has declared a distribution of one right for each share of Hologic Common Stock outstanding as of the close of business on December 31, 2002. Initially, the rights will trade automatically with the Common Stock and separate Right Certificates will not be issued. Each right entitles the registered holder to purchase one one-thousandth of a share of Hologic's Series A Junior Participating Preferred Stock at a purchase price of $60.00. The rights will be exercisable if a person or group acquires beneficial ownership of 15% or more of Hologic's Common Stock or announces a tender or exchange offer for 15% or more of the Common Stock. At such time, each holder of a right (other than the 15% holder) will thereafter have a right to purchase, upon payment of the purchase price of the right, that number of shares of Hologic Common Stock which have a market value of twice the purchase price of the right. The new rights plan is designed to deter coercive or unfair takeover tactics and to ensure that all Hologic shareholders receive fair and equal treatment in the event of an unsolicited attempt to acquire the Corporation. The new rights plan was not adopted in response to any effort to acquire Hologic, and the Board is not aware of any such effort. A detailed summary of the rights will be mailed to stockholders of record on December 31, 2002, and a complete copy of the plan will be filed with the SEC.
