Quantumsphere Acquisition Corp Terminates Merger with SACH/Omnivate

What Happened
Quantumsphere Acquisition Corporation (QUMS) filed an 8-K stating that the Company and its affiliated purchaser entities delivered a Termination Notice on September 1, 2026, terminating the Agreement and Plan of Merger dated October 3, 2025 with Omnivate Global Ltd. and SACH Pte. Ltd. The Purchaser Parties had earlier provided SACH notice on July 14, 2026 allowing a thirty-day cure period under the Merger Agreement; after that period expired, the Purchaser Parties elected to terminate the agreement in accordance with Section 13.2(a). As a result, the transactions contemplated by the Merger Agreement will not be consummated.

Key Details

• Merger Agreement originally dated October 3, 2025 between QUMS, Omnivate Global Ltd., SACH Pte. Ltd., QUMS Pubco Ltd. and SACH Merge Sub Ltd.
• Purchaser Parties (the Company, QUMS Pubco Ltd. and SACH Merge Sub Ltd.) delivered a termination notice on September 1, 2026 pursuant to Section 13.2(a).
• Prior notice regarding issues under the Merger Agreement was given on July 14, 2026 with a 30-day period to address those matters.
• The Company filed the Termination Notice as Exhibit 10.1 and a related press release as Exhibit 99.1 to the Form 8-K.

Why It Matters
The announced termination means the previously contemplated merger/acquisition between QUMS and SACH/Omnivate will not occur. For investors, this closes the specific path to any strategic, operational or financial changes that would have resulted from that transaction. The filing also notes the Purchaser Parties have reserved their rights and remedies under the agreement and applicable law; investors should review the Termination Notice and the original Merger Agreement (previously filed) for details and monitor QUMS disclosures for next steps or alternative plans.
