SMITH A O CORP 10-Q

ITEM 2 - UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS In the first quarter of 2021, our Board of Directors approved adding 7,000,000 shares of common stock to the existing discretionary share repurchase authority. Under the share repurchase program, the Common Stock may be purchased through a combination of Rule 10b5-1 automatic trading plan and discretionary purchases in accordance with applicable securities laws. The number of shares purchased and the timing of the purchases will depend on a number of factors, including share price, trading volume and general market conditions, as well as working capital requirements, general business conditions and other factors, including alternative investment opportunities. The stock repurchase authorization remains effective until terminated by our Board of Directors which may occur at any time, subject to the parameters of any Rule 10b5-1 automatic trading plan that we may then have in effect. In the third quarter of 2021, we repurchased 198,810 shares at an average price of $69.48 per share and at a total cost of $13.8 million. As of September 30, 2021, there were 5,436,357 shares remaining on the existing repurchase authorization.
