He has made outstanding contributions to both Nucor’s strong record of profitable growth and our company’s unique culture. Under Mike’s leadership, our Bar Mill Group more than doubled in size to a current finished steel shipment capacity exceeding 9 million tons annually. With his team’s very successful work in optimizing existing operations and completing strategic acquisitions, the growth in the earnings power of our bar products business has been even greater. Mike’s retirement and Jim Darsey’s promotion result from the thoughtful and orderly succession planning that has been a top strategic initiative throughout the Nucor organization in recent years as we position our company for continued profitable growth. Jim Darsey is a proven Nucor leader. He has a strong record of success in managing both the steel mill and downstream products sides of our business. Jim and his team are well-prepared to continue building long-term profitable growth at Nucor’s bar products business.
