Strengthening Our Core

4 RELIANCE STEEL & ALUMINUM CO.

Reliance prioritizes maintaining a strong balance sheet so that as we grow our business, we increase our capacity to give back and provide meaningful stockholder returns. Over $1 billion has been paid to stockholders through dividends and share repurchases during the past five years. In 2017, we achieved our second- highest annual diluted earnings per share of $5.52. * Confidence in Reliance’s outlook led us to repurchase $25 million of our company stock in the fourth quarter of 2017. And believing in our ability to execute profitably and grow our business has resulted in substantial dividend increases over the last several years. In 2017, we paid out $132 million in cash dividends; in the first quarter of 2018 we increased our regular quarterly dividend 11.1% to $0.50 per share, or an annual dividend of $2.00 per share.
