for the Fourth Quarter and Year Ended 2021 (Continued)

Financial Strength

At the end of the fourth quarter of 2021, Nucor had $2.76 billion in cash and cash equivalents, short-term investments and restricted cash and cash equivalents on hand. The Company’s $1.75 billion revolving credit facility remains undrawn and does not expire until November 2026. Nucor continues to have the strongest credit rating in the North American steel sector (Baa1/A-) with stable outlooks at both Moody’s and Standard & Poor’s.

Commitment to Returning Capital to Stockholders

During the fourth quarter of 2021, Nucor repurchased approximately 13.5 million shares of its common stock at an average price of $111.63 per share (33.8 million shares in the full year 2021 at an average price of $96.92 per share). On December 2, 2021, Nucor’s Board of Directors approved a new share repurchase program under which Nucor is authorized to repurchase up to $4.00 billion of Nucor’s common stock and terminated any previously authorized share repurchase programs. As of December 31, 2021, Nucor had approximately 272,000,000 shares outstanding and approximately $3.8 billion remaining available for repurchases under its share repurchase program.

On December 2, 2021, Nucor’s Board of Directors declared a cash dividend of $0.50 per share. This cash dividend is payable on February 11, 2022 to stockholders of record as of December 31, 2021 and is Nucor’s 195^th consecutive quarterly cash dividend. Nucor has increased its regular, or base, dividend for 49 consecutive years – every year since it first began paying dividends in 1973. For the full year 2021, Nucor returned approximately $3.76 billion to stockholders in the form of share repurchases and dividend payments.

Fourth Quarter of 2021 Analysis

Steel mills segment earnings in the fourth quarter of 2021 were comparable to the third quarter of 2021 despite lower volumes and a planned outage for the month of December at our sheet mill in Kentucky. The steel products segment generated increased earnings in the fourth quarter of 2021 as compared to the third quarter of 2021 as demand in nonresidential construction markets remained strong. Raw materials segment earnings decreased in the fourth quarter of 2021 as compared to the third quarter of 2021 primarily due to margin compression at our direct reduced iron facilities.

First Quarter of 2022 Outlook

End use market demand remains strong for steel and steel products, and we are confident that 2022 will be another year of strong profitability for Nucor. We expect consolidated net earnings attributable to Nucor stockholders in the first quarter of 2022 will be slightly reduced from the record results of the fourth quarter of 2021. Diluted earnings per share for first quarter of 2022 will benefit from lower weighted average shares outstanding.

Nucor Reports Record Quarterly and Annual Earnings

for the Fourth Quarter and Year Ended 2021 (Continued)

Steel mill segment earnings are expected to decline in the first quarter of 2022 due to decreased profitability of our sheet mills. The steel products segment is expected to achieve further margin expansion and profitability in the first quarter of 2022 as backlog pricing has improved reflecting higher steel costs. Earnings of the raw materials segment are expected to improve slightly in the first quarter of 2022 as compared to the fourth quarter of 2021 due to the improved profitability of our direct reduced iron facilities, partially offset by the impact of lower scrap prices on our scrap brokerage and processing operations.
