Pursuant to the Order, upon issuance, the Settlement Shares may be resold without restriction, subject to a partial lock-up provision. Under the lock-up, each Holder may not sell more than its pro rata portion of 20% of the daily trading volume of the Company’s common shares on any trading day. This restriction is subject to early termination under certain conditions, including a capital raise by the Company or a sustained increase in trading volume.

Mutual Releases; Effectiveness

The mutual releases of all claims related to the Matter as set forth in the Settlement Agreement became effective upon entry of the Order on August 13, 2025.

Status and Next Steps

The Company expects to issue the Settlement Shares to the Holders on or about August 15, 2025, in accordance with the Order and the Settlement Agreement, and will cause its transfer agent to register such shares accordingly. The Company may make additional disclosures in future reports to reflect the completion of issuance(s) under the Settlement Agreement and any subsequent developments.
