Hologic Announces Completion of Acquisition of Trex Medicals' U.S. Assets
Hologic positioned to capture a dominant stake in bone densitometry, mammography and direct-to-digital radiography markets.

Hologic, Inc. (NASDAQ: HOLX), a leading manufacturer of bone densitometers and digital general radiography systems, today announced that it has completed the acquisition of the U.S. business assets of Trex Medical Corporation (AMEX: TXM), a Thermo Electron company. Trex Medical manufactures the leading X-ray mammography systems used worldwide for the detection and diagnosis of breast cancer. In addition, Hologic acquired the business activities of Trex Medical in the areas of mobile x-ray systems, X-ray systems for non-destructive testing, specialized medical X-ray imaging equipment for cardiac catheterization laboratories, digital radiographic/fluoroscopic (R/F) systems, electrophysiology products and general radiography products. Hologic has taken over approximately 550 employees at Trex Medical's current 62,500 square foot research and development, manufacturing and administrative site in Danbury, Connecticut and Trex Medical's 156,000 square foot leased facility in Littleton, Massachusetts; and has acquired 49 issued U.S. and foreign patents. Revenues associated with the acquired business for the quarter ended July 1, 2000 totaled approximately $30 million.

The acquisition, which was announced on August 15, 2000, is valued at approximately $55 million and is comprised of $30 million in cash and a secured note in the amount of $25 million (with a term of 3 years). Hologic will use the purchase accounting method for the acquisition. Since the current operations of Trex Medical are unprofitable, management expects this transaction initially to be dilutive to earnings.

Trex Medical's products address the general-purpose and specialized medical X-ray markets with a broad range of products. The company serves the mammography market with state-of-the-art breast-imaging units and minimally invasive breast-biopsy systems. The breast-biopsy systems offer women a less traumatic option to open surgical breast biopsy.

Trex's mammography systems incorporate the High Transmission Cellular (HTC™) Imaging System, the most effective contrast improvement in 20 years of breast imaging. The patented HTC technology is unique in that it reduces X-ray scatter in both the x and y dimensions, delivering superior contrast and resolution without an increase in dose.

S. David Ellenbogen, Hologic's Chairman and CEO stated, "This acquisition solidifies our position as the leading x-ray manufacturer for women's health. Our key business assets remain technological leadership and the ability to pioneer new markets. We are committed to expanding our contributions in the field of osteoporosis management and breast cancer detection. At the same time, we will continue to develop new x-ray systems that incorporate our direct-to-digital radiographic imaging technology for both women's health and general radiographic applications. We believe that the digital x-ray equipment market has the potential to exceed $1 billion within the next few years. Our goal is to position the Company to generate sales in excess of $200 million in calendar 2001 from bone densitometry, mammography, c-arm imaging and digital radiography."
