EchoStar Corporation (“EchoStar”) has elected not to make approximately $183 million in cash interest payments due on June 1, 2026 (the “Interest Payments”) with respect to its DISH DBS Corporation (“DDBS”) subsidiary’s 5.25% secured notes due 2026 (the “2026 Notes”), 5.75% secured notes due 2028 (the “2028 Notes”) and 5.125% unsecured notes due 2029 (the “2029 Notes, and collectively with the 2026 Notes and the 2028 Notes, the “DBS Notes”) comprised of approximately $72.2 million under the 2026 Notes, $71.9 million under the 2028 Notes and $38.4 million under the 2029 Notes. Under each of the indentures governing the DBS Notes (the “DBS Notes Indentures”), such non-payment is a default and we have a 30-day grace period to make the Interest Payments before such non-payment constitutes an Event of Default (as such term is defined in the DBS Notes Indenture) with respect to the DBS Notes.

​

EchoStar elected not to make the Interest Payments on the due date to defer liquidity utilization pending the receipt of net closing proceeds of $20.25 billion from the AT&T Transactions (as defined in EchoStar’s SEC filings). The AT&T Transactions have received regulatory approvals from both the Federal Communications Commission (FCC) and the Department of Justice (DOJ); however, the FCC’s approval remains subject to the FCC’s order becoming final. Consummation of the AT&T Transactions remains subject to the satisfaction or waiver of certain other closing conditions as described in EchoStar’s Current Report on Form 8-K filed on August 26, 2025.
