Conclusion regarding disclosure controls and procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934) as of the end of the period covered by this report. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.

Changes in internal control over financial reporting

Effective June 30, 2026, our control environment was modified in response to our subsidiary, DISH DBS Corporation and certain of its subsidiaries (“DISH DBS Filing Entities”), including DISH Wireless L.L.C. and its subsidiaries (the “DISH Wireless Filing Entities,” and together with DISH DBS Filing Entities, the “Filing Entities”), having commenced voluntary cases under chapter 11 of the United States Bankruptcy Code (the “Prepackaged Chapter 11 Cases”) in the United States Bankruptcy Court for the Southern District of Texas (the “Bankruptcy Court”), Houston Division, to pursue confirmation of a joint prepackaged plan of reorganization (the "Prepackaged Chapter 11 Plan") that restructures certain liabilities of the DISH DBS Filing Entities and DISH Wireless Filing Entities.

We removed internal control activities unique to the operational environments of the Filing Entities from the scope of our integrated controls.

To address the resulting incremental financial reporting risks and ensure completeness and accuracy of our financial statements, management designed and implemented the following incremental internal controls as of June 30, 2026:

The modifications during the quarter ended June 30, 2026, described above, regarding the deconsolidation of the Filing Entities were also applied to the deconsolidation of the Hughes Filing Entities, described below.

Effective July 31, 2026, our control environment was modified in response to our subsidiary, Hughes Satellite Systems Corporation (“Hughes”) and certain of its U.S. subsidiaries, including Hughes Network Systems, LLC, (the “Hughes Filing Entities”), having commenced voluntary cases under chapter 11 of the United States Bankruptcy Code (the “Hughes Chapter 11 Cases”) in the United States Bankruptcy Court for the Southern District of Texas (the “Bankruptcy Court”), Houston Division, to pursue confirmation of a plan of reorganization (the "Hughes Chapter 11 Plan").

Apart from the modifications described above, there has been no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
