Altaris Capital Partners has agreed to buy imaging technology developer Analogic Corp. (Nasdaq: ALOG) in a take-private deal for about $1.1 billion. Analogic, based in Peabody, Massachusetts, makes advanced imaging and real-time guidance technologies used for disease diagnosis and treatment, as well as for automated threat detection. Analogic’s ultrasound systems, led by its flagship BK Ultrasound brand, are used in procedure-driven markets such as urology, surgery, and point-of-care. The company’s technologies are also used in computed tomography, magnetic resonance imaging, and digital mammography systems, as well as automated threat detection systems for aviation security. Over the last 15 years, Altaris made 34 investments and has “deep experience in the manufacturing and marketing of medical devices, imaging technologies and diagnostic equipment,” says the company. The transaction follows a comprehensive strategic review process that was publicly announced on June 6. “Analogic’s three business units present a range of business models and investment needs, each of which is subject to its own market conditions,” Analogic chairman Bernard Bailey said in a statement. “In light of these factors, the board considered the long-term positioning of Analogic in each of its markets. Analogic’s growth outlook requires continued strategic investment into new channels to market, which involves risk, especially given the pace of change in its served markets.” Analogic will represent Altaris’ 17th company to design and manufacture high-value, FDA-regulated medical products. “Analogic has a rich history of developing advanced technologies that have enabled innovation in medical imaging and security screening,” said George Aitken-Davies, co-founder and managing director of Altaris. “We look forward to building on this heritage and continuing to provide technology-driven imaging solutions and world-class service to the industry.” Citigroup Global Markets Inc. (NYSE: C) and Wilmer Cutler Pickering Hale are advising Analogic. Schiff Hardin LLP is representing Altaris.
