On May 20, 2026, BKV Corporation and its subsidiaries entered into the Sixth Amendment to their Credit Agreement with Citibank, N.A. This amendment modifies the reserve-based lending agreement dated June 11, 2024. Key changes include an increase in the maximum permitted net leverage ratio for restricted payments and voluntary debt prepayments/redemptions. Specifically, the ratio for restricted payments calculated based on distributable free cash flow increased from a range of 2.00-1.00 to 2.25-1.00, and for additional restricted payments, it increased from 1.75-1.00 to 2.00-1.00.
