Share price reaction
The filing reached SEC EDGAR on 30 September 2026 at 12:44 New York time, during trading hours, so day 0 is that same day. Day 0 is marked by the vertical line.
| Window | MAT | S&P 500 | Abnormal |
|---|---|---|---|
| Days 0 to +1 | +13.8% | −0.0% | +14.8% |
| Days 0 to +3 | +21.4% | +1.4% | +20.7% |
| 1 month (days 0 to +21)so far, 20 of 22 days | +16.7% | +0.7% | +19.6% |
| 3 months (days 0 to +63)so far, 20 of 64 days | +16.7% | +0.7% | +19.6% |
The abnormal return is the stock's return beyond what its usual relationship with the market (beta 0.74) predicts. A single stock's move can reflect other news on the same days, so it describes what happened rather than measuring the effect of the CEO change; averages across many events are on the Research design page as they are completed.
