During this time, MSC's Executive Management Team and Board of Directors will be conducting a comprehensive search to identify a permanent CFO.

Mr. Gershwind said, "During her nearly five-year tenure as CFO, Kristen has contributed to our performance and built a strong team.

Gershwind continued, "I am encouraged by our start to the fiscal fourth quarter and remain confident in our long-term trajectory. Average daily sales for the fiscal month of June came in ahead of expectations and were up 2.5% year-over-year. July's average daily sales growth rate remains in positive territory. As of now, based upon June and July results quarter to date, our fiscal fourth quarter performance is trending towards the upper half of our average daily sales and adjusted operating margin ranges that we provided in our July 1, 2025 earnings release."
