Exhibit 99(a)(3) PRESS RELAEASE - -------------------------------------------------------------------------------- [LOGO] FOR IMMEDIATE RELEASE CONTACT: ANNE BUGGE, U.S.A., (425) 487-7427 JEREMY COHEN, AMSTERDAM, 31 20 59 77213 PHILIPS TO ACQUIRE ATL IN $800 MILLION TRANSACTION AMSTERDAM AND SEATTLE, JULY 29, 1998--Royal Philips Electronics of the Netherlands (AEX:PHI, NYSE:PHG) and ATL Ultrasound of the United States (NASDAQ:ATLI) announced today that ATL and Philips have signed a definitive merger agreement for Philips to acquire all of the outstanding shares of ATL for approximately $800 million or $50.50 per share for each outstanding share of ATL common stock. The transaction will be a cash tender offer followed by a cash merger to acquire any shares not previously tendered. As a result of the transaction, ATL will become a wholly owned subsidiary of Philips Medical Systems. The ATL Board of Directors has unanimously approved the transaction. Philips expects to commence its cash tender offer August 4, 1998. The cash tender offer is subject to Philips receiving at least a majority of the fully diluted shares of ATL in the tender offer as well as the receipt of customary regulatory approvals. ATL, with annual revenues of $430 million in 1997 and 2,600 employees, pioneered the development of broadband digital ultrasound and software technologies and is a leader in the high performance ultrasound market. The ultrasound sector is the only part of the diagnostic imaging business in which Philips Medical Systems does not play a major role. "ATL is a technological leader in diagnostic ultrasound and offers a key growth opportunity for Philips Medical," says Hans (J.M.) Barella, Chairman and CEO of Philips Medical Systems. "This acquisition underscores our commitment to global leadership in worldwide diagnostic imaging by building on the success of ATL." Philips Medical Systems is already a global leader in the x-ray business and diagnostic imaging systems and services. 2 ATL has an especially strong presence in the United States and Europe. The complementary businesses of Philips Medical Systems and ATL allow for the building of significant synergies. ATL's strong management, solid financial performance and business growth opportunity make this an excellent acquisition for Philips. The merger will provide ATL access to Philips Medical Systems' considerable research and technology base, expand its service support and further increase sales. "Combining the strengths of Philips Medical Systems and ATL creates a diagnostic imaging business second to none," said Dennis C. Fill, ATL Chairman and CEO. "With essentially no overlap in our products and technologies, we believe this combination is the perfect match for both companies. This merger is particularly good for the long-term prospects of ATL and all our employees as we will become the worldwide center of Philips for ultrasound with our headquarters remaining in Bothell. ATL will be an even stronger force in ultrasound than it already is." Ultrasound is the fastest growing sector of the medical imaging business today, and worldwide revenues for ultrasound are approximately $2.5 billion per year. Ultrasound is a non-invasive technology that uses high frequency soundwaves to image the body's organs, soft tissue and blood flow in real time. Three-dimensional imaging has led to a growing diagnostic role for ultrasound. Philips has recently stated that it would only look for acquisitions that would strengthen its existing portfolio, and this agreement reflects that strategy. The transaction affirms Philips' commitment to its Medical Division as one of the building blocks of the company and one where value can be added and increasing profits realized. Philips Medical Systems is delivering a consistently profitable performance with steady growth and a strong cash flow, and this merger will enable the division to contribute more significantly to the sales and results of the Philips Group. The transaction is expected to have a positive impact on earnings per share for Philips.
