Spark I Acquisition Corp. held an extraordinary general meeting on September 25, 2026, to approve extending the deadline for its initial business combination from September 29, 2026, to March 29, 2027.
In connection with the meeting, holders of 609,668 Class A ordinary shares exercised redemption rights for a pro rata portion of trust funds, including interest. As of October 2, 2026, approximately $7.1 million (approximately $11.68 per share) was removed from the Trust Account to pay holders, leaving approximately $19.0 million. Spark I reported 6,445,104 Class A ordinary shares outstanding following the redemptions.
Spark I Acquisition Corp. (SPKL) received Nasdaq notice that its securities will be delisted because it did not complete an initial business combination by September 29, 2026, as required by Nasdaq Interpretive Material IM-5101-2. Trading in its Class A ordinary shares, units and warrants is scheduled to be suspended at the opening of business on October 7, 2026; Nasdaq said it will file a Form 25-NSE to remove the securities from listing and registration.
After delisting, Spark I expects the securities to be quoted on the Pink Limited Market under SPKL, SPKLU and SPKLW, respectively, but said there is no guarantee a broker will make a market or trading will continue. Spark I still intends to complete its proposed business combination with ZincFive and seek a listing on Nasdaq or another national securities exchange in connection with it, as soon as practicable, but gave no assurance the transaction or listing will succeed. The related registration statement filed September 30, 2026, was not yet effective, and its preliminary proxy statement/prospectus was incomplete and subject to change.
Spark I Acquisition Corporation furnished an investor presentation about its proposed business combination with ZincFive, which supplies nickel-zinc batteries and solutions for data-center backup power and AI-related power demands. The presentation states a proposed $762 million enterprise value, describes $100 million in proceeds from a committed Preferred Equity PIPE, and says ZincFive shareholders would roll over 100% of their equity. Spark I had $26 million in trust as of September 30, 2026; the presentation’s closing capitalization assumes no Spark I shareholder redemptions.
ZincFive reported first-half 2026 revenue of $38.9 million, versus $34.9 million in first-half 2025, and an operating loss of $26.3 million versus $24.7 million. Revenue was $28.7 million in 2024 and $65.0 million in 2025. Contracted backlog was $126.5 million as of June 30, 2026, and its 2026 revenue forecast was $90.0 million to $105.0 million. The forecast is illustrative; the Form S-4 filed September 30, 2026 had not been declared effective, and the proposed transaction is to be submitted to Spark I shareholders.
Spark I Acquisition Corp (SPKL) will make a one-time additional deposit into its Trust Account of $0.10 per public share not redeemed in connection with its extraordinary general meeting, scheduled for October 5, 2026. The contribution will be in addition to monthly Sponsor Contributions and will increase the per-share price payable for EGM-related redemptions or upon liquidation, whichever occurs first.
Public shareholders who already submitted an EGM redemption request may withdraw it by contacting Continental by 5:00 p.m. Eastern time on October 2, 2026. Those who do not withdraw by then will receive the original redemption price, estimated at approximately $11.60 per share.
Spark I Acquisition Corp (SPKL) shareholders approved extending the deadline for an initial business combination from September 29, 2026, to March 29, 2027, or an earlier date set by the board. The vote was 7,074,069 for, 57,456 against and zero abstentions; the amendment took effect upon approval.
Under the extension, the sponsor, SLG SPAC Fund LLC, agreed to make trust-account loans beginning October 1 at $0.015 per public share outstanding after redemptions, up to approximately $201,304 in aggregate. The company issued the sponsor a no-interest note with principal up to $400,000, repayable in full upon the earlier of a business combination or March 29, 2027. If no combination is completed by then, repayment is limited to funds outside the trust account or the note may be forfeited, eliminated or forgiven. The company also plans a one-time $0.10 deposit per public share not redeemed in connection with the meeting, scheduled for October 5; it will increase the per-share price payable in connection with a vote on the proposed ZincFive combination or liquidation, whichever is earlier. Holders who submitted redemption requests may withdraw them by October 2 at 5:00 p.m. Eastern; otherwise, the estimated original redemption price is approximately $10.92 per share.
Spark I Acquisition Corporation agreed to merge with ZincFive, Inc., taking the nickel‑zinc battery maker public in a SPAC business combination. The deal assigns ZincFive an equity value of $600 million, with a separate press release citing a pro forma enterprise value of about $752 million. Spark I will domesticate from Cayman to Delaware and be renamed New ZincFive, Inc., with all SPAC shares, warrants and units converting into New ZincFive equity.
ZincFive shareholders will roll their interests into New ZincFive and receive common stock based on an exchange ratio derived from the $600 million equity value. Concurrently, institutional investors agreed to purchase 10,441,174 shares of New ZincFive 12.0% Series A Cumulative Convertible Preferred Stock plus matching common stock warrants for total proceeds of $106.5 million. The preferred carries a 12% in‑kind or 10% cash dividend, strong protective rights and is convertible at an initial $12.00 price.
Closing is targeted for the second half of 2026, subject to shareholder approvals, a minimum $100 million “Available Closing Cash” condition, effectiveness of a Form S‑4 registration statement, domestication, and stock exchange listing of New ZincFive. Sponsor and company support agreements, lock‑ups and an amended registration rights agreement align insiders and key holders to back the transaction and govern future share sales.
