Securities Trading Plans of Directors and Executive Officers

On February 10, 2026, James C. Grech, President & Chief Executive Officer and a member of the Company’s Board of Directors, adopted a Rule 10b5-1 trading arrangement (as such term is defined in Item 408 of Regulation S-K), which is designed to be in effect until December 31, 2027, subject to customary exceptions. Mr. Grech’s Rule 10b5-1 trading arrangement calls for the sale of up to 54,500 shares, subject to certain conditions.

On February 23, 2026, Scott T. Jarboe, Chief Administrative Officer and Corporate Secretary, adopted a Rule 10b5-1 trading arrangement (as such term is defined in Item 408 of Regulation S-K), which is designed to be in effect until January 31, 2028, subject to customary exceptions. Mr. Jarboe’s Rule 10b5-1 trading arrangement calls for potential sales of a percentage of shares that he could receive upon the future vesting of certain outstanding equity awards, net of any shares withheld by Peabody to satisfy applicable taxes. The number of shares to be withheld, and thus the exact maximum number of shares to be sold pursuant to Mr. Jarboe’s Rule 10b5-1 trading arrangement, can only be determined upon the occurrence of the future vesting events. For purposes of this disclosure, without subtracting any shares to be withheld upon future vesting events, the maximum aggregate number of shares to be sold pursuant to Mr. Jarboe’s Rule 10b5-1 trading arrangement is 45,545.

Except as set forth above, during the three months ended March 31, 2026, none of Peabody’s directors or officers adopted orterminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as these terms are defined in Item 408 of Regulation S-K of the Exchange Act.
