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.

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 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 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.
