**ADDITIONAL DEFINITIVE PROXY SOLICITING MATERIAL** 

This additional definitive proxy soliciting material is being filed to correct typographical errors contained in the Definitive Proxy Statement on Schedule 14A filed by SunCoke Energy, Inc. (the "Company") with the Securities and Exchange Commission (the "SEC") on April 1, 2026 (the "Proxy Statement") in connection with the Company's Annual Meeting of Stockholders to be held on May 14, 2026 at 8:00 a.m. Central Time (the "Annual Meeting").

**Corrections** 

The second table appearing on page 11 of the Proxy Statement under the heading "THE BOARD OF DIRECTORS AND ITS COMMITTEES" contained typographical errors. Specifically, Katherine T. Gates was incorrectly indicated as a member of the Compensation Committee and Arthur F. Anton was inadvertently omitted as a member of the Compensation Committee. The corrected table is set forth below and supersedes the corresponding table in the Proxy Statement in its entirety. The only changes from the table as it appeared in the Proxy Statement are the removal of the checkmark (✓) next to Katherine T. Gates' name and the addition of the checkmark (✓) next to Arthur F. Anton's name, in each case under the "Compensation" column.

The following table shows the proposed membership of our Committees following SunCoke Energy's 2026 Annual Meeting:
