Plum Acquisition Corp. III filed a Form 15 to terminate the registration of its securities under Section 12(g) of the Exchange Act and to suspend its duty to file periodic reports under Sections 13 and 15(d). The filing covers its units, Class A ordinary shares, and redeemable warrants, each whole warrant exercisable for one Class A ordinary share at an exercise price of $11.50. The company reports an approximate number of holders of record of these securities as none as of the certification date.
Plum Acquisition Corp. III reports that Marcum LLP resigned as its independent registered public accounting firm on June 3, 2026. Marcum’s attest business was acquired by CBIZ CPAs P.C. effective November 1, 2024, and Marcum continued as auditor through the resignation date.
For the fiscal years ended December 31, 2025 and 2024, Marcum’s audit reports contained no adverse opinions, disclaimers, or qualifications regarding uncertainty, scope, or accounting principles. The company states there were no disagreements or reportable events with Marcum over accounting, disclosure, or audit procedures, except for a previously disclosed material weakness in internal control over financial reporting referenced in its 2025 Form 10-K and March 31, 2026 Form 10-Q. The company provided this disclosure to Marcum and filed Marcum’s related letter as Exhibit 16.1.
Plum Acquisition Corp. III completed a change of jurisdiction on July 27, 2026, continuing from the Cayman Islands to the Province of British Columbia, Canada under the Cayman Companies Act and the Business Corporations Act (British Columbia). After this Domestication, the entity operates as Canadian Plum, subject to Canadian and provincial law.
Each outstanding Class A ordinary share, warrant and unit automatically became a registered security of Canadian Plum. The Class A shares, warrants and units continue to trade on the OTC Markets under the symbols PLMJF, PLMWF and PLMUF, and are deemed registered under Section 12(b) of the Exchange Act pursuant to Rule 12g-3(a). The Domestication was undertaken in anticipation of a planned Business Combination among Canadian Plum, Pubco, Amalco and Tactical Resources Corp., involving successive amalgamations in which Pubco and Tactical would be the surviving entities, as further detailed in Pubco’s F-4 registration statement.
Plum Acquisition Corp. III has called a July 29, 2026 extraordinary meeting to ask shareholders to extend the deadline to complete its previously approved business combination with Tactical Resources Corp. from July 30, 2026 to December 31, 2026 through an Articles Extension.
Holders of Class A Public Shares may redeem for their pro rata share of the Trust Account if the extension is implemented. As of July 15, 2026, the Trust held approximately $501,297, implying a redemption price of about $11.80 per share, compared with a May 1, 2026 OTC Pink trading price of $10.40.
If the extension is not approved and the business combination is not completed by July 30, 2026, Plum would cease operations, redeem all Public Shares from the Trust Account and liquidate, and its warrants would expire worthless. Initial shareholders, who hold 97.0% of outstanding ordinary shares, intend to vote in favor of both the extension and a related adjournment proposal.
Plum Acquisition Corp. III reported Q1 2026 net income of $4.4 million, mainly from a $4.6 million non‑cash gain on warrant liabilities. Core operations remain minimal, with general and administrative expenses of $0.24 million versus $0.53 million a year earlier.
The SPAC held $497,828 in its trust account and only $438 of cash outside the trust as of March 31, 2026, against a working capital deficit of $6.2 million and related‑party promissory notes totaling $2.16 million. Extensive redemptions have reduced Class A shares subject to redemption to 42,486, and the company must complete its business combination by July 30, 2026 or liquidate, leading management to highlight substantial doubt about its ability to continue as a going concern.
Plum Acquisition Corp. III submitted a Form 12b-25 notification stating it cannot timely file its Quarterly Report on Form 10-Q for the period ended March 31, 2026 because it needs additional time to complete its final review of financial statements and other disclosures. The company states it expects to file within the five-day extension provided under Rule 12b-25. The notification is signed by Kanishka Roy, President and Chief Executive Officer, dated May 18, 2026.
Plum Acquisition Corp. III reported that Tactical Resources Corp. entered into an Asset Purchase Agreement to buy approximately 1.5 million tons of processed tailings from Sierra Blanca Quarry in Texas. At closing, Plum’s post‑combination entity, PubCo, is expected to issue about 3,000,000 common shares to the seller as consideration, conditional on completion of Plum’s previously announced business combination with Tactical.
The attached Tactical press release explains that these crushed aggregate tailings are intended as potential feedstock for Tactical’s Peak Rare Earth Project and could help reduce traditional mining and permitting timelines. A prior Purchase and Sale Agreement also gives Tactical an option to acquire 100% of Sierra Blanca Quarry’s membership interests for US$29,000,000, half in cash and half in equity, along with access to additional tailings.
Plum Acquisition Corp. III, a Cayman Islands SPAC, reports on its efforts to complete a business combination, currently planned with Tactical Resources Corp. under an August 2024 Business Combination Agreement. The SPAC raised $250.0 million in its IPO and placed about $282.5 million into a trust account.
Successive shareholder redemptions have sharply reduced the trust, leaving about $486,624 after the July 2025 meeting and additional contingent redemptions approved in December 2025. The company faces a July 30, 2026 deadline to close a deal or liquidate, and its 10‑K notes substantial doubt about its ability to continue as a going concern.
Plum’s securities were delisted from Nasdaq in January 2025 and now trade on the OTC Markets under tickers PLMJF, PLMWF, and PLMUF. Shareholders retain redemption rights in connection with the current or any alternative business combination and in the event of further charter amendments or liquidation.
Plum Acquisition Corp. III reported the results of its Extraordinary General Meeting held on December 22, 2025, where shareholders overwhelmingly approved its cross-border reorganization and planned business combination. Holders of 7,911,075 Common Shares, or 99.26% of shares entitled to vote, were present, providing a strong quorum.
Shareholders approved the Domestication Proposal to move from the Cayman Islands to British Columbia and the Business Combination Proposal with Tactical Resources Corp., enabling the multi-step amalgamation structure described in the Business Combination Agreement. They also backed new governance documents, including changing the authorized capital to an unlimited number of PubCo common shares and renaming the company to Tactical Resources Corporation.
Investors further approved a Nasdaq-related proposal covering the issuance of PubCo common shares for the business combination and authorizing issuance of up to $100,000,000 of PubCo common shares to Yorkville over 36 months, as well as an omnibus equity incentive plan. An adjournment proposal was not needed because sufficient votes were already obtained.
Plum Acquisition Corp. III disclosed a financing arrangement tied to its proposed business combination: Pubco (Plum III Merger Co.) and Tactical Resources Corp. entered a standby equity purchase agreement with Yorkville for up to $100,000,000, plus staged pre‑paid advances. Yorkville will provide a $7,500,000 pre‑paid advance via a convertible promissory note at closing of the business combination, a further $2,500,000 pre‑paid advance via a non‑convertible note when the initial Form F‑1 becomes effective, and up to $30,000,000 may be available as a third pre‑paid advance via a convertible note if agreed by Yorkville and Pubco.
Each pre‑paid advance carries an original issue discount, and additional draws under the equity line are subject to conditions in the SEPA. The SEPA ends on the earlier of 36 months or use of the full $100,000,000. Yorkville also receives a 24‑month right of first refusal on any at‑the‑market program. Pubco will file a Form F‑1 within 30 days after closing to register the SEPA and will use best efforts to have it declared effective as soon as practicable, but no later than 60 days after filing.
