"Al Costello is the right person to lead the continued global growth of W. R. Grace," said Thomas A. Holmes, who headed the Board's CEO Search Committee and had served as acting CEO since March 2. "He brings to Grace nearly four decades of man- agement and leadership experience." "There is a tremendous potential for continued growth within the businesses of W. R. Grace," said Costello, "and I am excited about being a part of that." PAGE W. R. Grace reported its 1995 first quarter results last week, noting a 56 percent increase in net operating earnings over the prior year quarter, and a 25 percent increase in sales. All of the Company's six core businesses and every geographic region contributed to the excellent results of the quarter. "The performance improvement recorded in 1994 appears to be gaining momentum in 1995," said Costello. "My focus will be on maintaining that momentum and enhancing value and opportunity for our shareholders, employees, customers and communities." The Company has agreed that Costello will be elected by the Board as a director and Chairman of the Board promptly after the Company's May 10, 1995 Annual Meeting. Under New York law, Costello will stand for reelection at the 1996 Annual Meeting. "Once I am elected Chairman, I will move expeditiously to fulfill the Board's commitment to its shareholders, and oversee the Company's governance in the best interests of all sharehold- ers," said Costello. "The Board is eager to move forward deci- sively, making sure that W. R. Grace's excellent current perfor- mance can continue uninterrupted." The CEO Search Committee comprised Holmes, Harold Eck- mann, Edward Duffy, Dr. George Dacey and Dr. James Frick -- all independent directors.
