Stock Repurchase Program	NOTE 12 — STOCK REPURCHASE PROGRAM On January 8, 2008, we announced our authorization of a stock repurchase program under which we may repurchase shares of RPM International Inc. common stock at management’s discretion. As announced on November 28, 2018, our goal was to return $1.0 billion in capital to stockholders by May 31, 2021 through share repurchases and the retirement of our convertible note during fiscal 2019. On April 16, 2019, after taking into account share repurchases under our existing stock repurchase program to date, our Board of Directors authorized the repurchase of the remaining $600.0 million in value of RPM International Inc. common stock by May 31, 2021. As previously announced, given macroeconomic uncertainty resulting from the Covid pandemic, we had suspended stock repurchases under the program, but in January 2021, our Board of Directors authorized the resumption of our stock repurchase program. At the time of resuming the program, $469.7 million of shares of common stock remained available for repurchase. The Board of Directors also extended the stock repurchase program beyond its original May 31, 2021 expiration date until such time that the remaining $469.7 million of capital has been returned to our stockholders. As a result, we may repurchase shares from time to time in the open market or in private transactions at various times and in amounts and for prices that our management deems appropriate, subject to insider trading rules and other securities law restrictions. The timing of our purchases will depend upon prevailing market conditions, alternative uses of capital and other factors. We may limit or terminate the repurchase program at any time. During the three and nine months ended February 28, 2023, we repurchased 143,096 and 446,175 shares of our common stock at a cost of approximately $12.5 million and $37.5 million, or an average of $87.35 per share and $84.05 per share. During the three and nine months ended February 28, 2022, we repurchased 171,933 and 305,321 shares of our common stock at a cost of approximately $15.0 million and $27.5 million, or an average of $87.24 per share and $90.07 per share. The maximum dollar amount that may yet be repurchased under our stock repurchase program was approximately $329.8 million at February 28, 2023.
