Subsequent Events	15. Subsequent Event On August 3, 2026, BBBC entered into an agreement to acquire certain assets of Detroit Chassis LLC, a Michigan limited liability company and the longtime manufacturer of Ford Motor Company’s (“Ford”) F53 (Class A motorhome) and F59 commercial (step-van, delivery, and logistics market) stripped chassis for Ford’s “F5X” commercial vehicle business. Also on August 3, 2026 but effective July 31, 2026, BBBC entered into a Master Collaboration Agreement with Ford, pursuant to which the BBBC will assume responsibility from Ford for the design and manufacture of the next generation F53 and F59 chassis, which will be paired with Ford’s powertrain solutions. The parties expect this collaboration agreement to support the continued evolution of the stripped chassis vehicle market and offerings, and ensure a seamless transition for Ford customers and fleets. Company management believes that the F53 and F59 chassis market represents a significant long-term growth opportunity for stockholders. Asset Purchase Agreement The Asset Purchase Agreement ("Purchase Agreement") pertaining to the Detroit Chassis Plant ("DCP") was executed by BBBC, Detroit Chassis LLC and Spectra LMP, LLC, a Michigan limited liability company (the “Member” and referred to with the DCP collectively as the “Sellers”). Pursuant to the Purchase Agreement, BBBC will acquire certain of Sellers' assets, including but not limited to, equipment, tooling, inventory, rights to leased real property, intellectual property, certain contracts and rights related thereto, permits, and goodwill and going concern value, all related solely to the F53/F59 chassis production (“Acquired Assets”) and will assume only the liabilities associated with the acquired assets and contracts (“Assumed Liabilities”). The purchase price (“Purchase Price”) to be paid to Sellers will be $7.0 million plus the assumption of the Assumed Liabilities. BBBC owes $700,000 of the Purchase Price to Sellers upon execution of the Purchase Agreement. At the closing of the transaction, BBBC will pay the balance of $6.3 million to Sellers minus the amount of any indebtedness of Sellers secured by any lien on the Acquired Assets. The transaction closing is anticipated to occur in the first calendar quarter of 2027, expected approximately thirty (30) days after the date that Ford ceases production of the F53/F59 commercial chassis. The DCP will continue to manufacture chassis under its agreement with Ford through the end of Ford production. The DCP’s workforce is covered under a collective bargaining agreement with United Auto Workers Local 155 (“UAW”). As part of its manufacturing assessment for the next-generation F-53/F-59 stripped chassis, BBBC intends to prioritize the existing DCP facility located in Detroit, Michigan as the primary path under evaluation, while collaborating with the UAW to leverage the experience of the existing workforce. The parties made customary representations, warranties, and covenants in the Purchase Agreement, including, but not limited to, the agreement of the parties to indemnify each other for certain breaches of representations and covenants, as well as other pre-closing matters. The Sellers agreed to certain non-competition and non-solicitation restricted periods following the transaction closing, subject to certain continued access and cooperation agreements between the parties. Master Collaboration Agreement The Master Collaboration Agreement (“MCA”) executed by Ford and BBBC is intended to further expand and strengthen the long-standing collaboration between the parties and will result in BBBC taking over the F53/F59 chassis business from Ford. New production is anticipated to begin in the first half of calendar year 2028. The new platform is expected to build on the strong legacy of the F53/F59 stripped chassis products while introducing a next-generation solution to address evolving customer requirements and regulatory standards. While no assurances can be given that the following can be achieved, Company management believes that the growth opportunity in this market represents the potential to achieve annual volume of approximately 10,000 units with potential annual revenue generation of $600 million or more. Pursuant to the MCA, Ford will supply BBBC with its proprietary powertrains and provide limited transition support services. BBBC will strive to utilize Ford’s powertrain technology, existing customer relationships, and transition support to capture profitable market share in this chassis segment. The parties will also enter into a powertrain supply agreement governing the specific terms related to the sale and purchase of the powertrains. The primary objectives of the MCA are: (i) the development by BBBC of a next generation replacement portfolio of stripped chassis products for the motorhome/recreational vehicle and commercial step-van, delivery, and logistics markets, and (ii) to ensure continuity of supply for Ford’s long-standing customer base, and to preserve and expand the customer base. The parties will conduct collaborative initial concentrated reviews of the feasibility and viability of the objectives under the MCA. Upfront investment and manufacturing costs will be borne by BBBC, with cooperative efforts by Ford. The target launch date for the replacement prototypes is January 1, 2028, or as mutually agreed between BBBC and Ford. All tooling and equipment related to the F5X commercial vehicle business owned by Ford will be sold and transferred to BBBC, with closing to be within thirty (30) days after the date that Ford ceases production of the F53/F59 commercial chassis. Ford has also agreed to a multi-year exclusivity period in favor of BBBC with respect to sales of its powertrain to non-Ford affiliated third party competitors in this market. Ford will support the transition of its existing customer base to BBBC.
