Masco Corporation (NYSE:MAS), today announced it has entered into an accelerated share repurchase ("ASR") agreement with Royal Bank of Canada to repurchase $300 million of Masco's common stock.

This agreement is part of Masco's existing share repurchase authorization under which $2 billion of authority was announced on February 10, 2026.

Under the ASR agreement, Masco will receive initial delivery of approximately 3.3 million shares on May 7, 2026 representing approximately 80 percent of the number of shares of common stock initially underlying the ASR agreement, based on the closing price of Masco's common stock of $71.95 on May 6, 2026.

The final number of shares to be repurchased will be based on Masco's volume-weighted average price during the term of the transaction, less a discount, and is expected to be completed no later than July 27, 2026.
