ITEM 7.01 — REGULATION FD DISCLOSURE

The Updated Earnings Release referenced in Item 2.02 above refers to certain supplemental information that was posted as a supplemental information package on the Company's website on November 4, 2026, which replaces and supersedes the Original Supplemental Package (the "Updated Supplemental Information Package").
