Subsequent Events [Abstract]
SUBSEQUENT EVENTS	NOTE 10. SUBSEQUENT EVENTS The Company evaluated subsequent events and transactions that occurred after the balance sheet date up to the date that the financial statements were issued. Based upon this review, other than as described below, the Company did not identify any subsequent events that would have required adjustment or disclosure in the financial statements. Proposed Business Combination On February 1, 2021, Tuscan entered into an agreement and plan of merger (the “Merger Agreement”) with Microvast, Inc., a Delaware corporation (“Microvast”) and Merger Sub. Pursuant to the Merger Agreement, Merger Sub will merge with and into Microvast and Microvast will survive the merger and become a wholly owned subsidiary of Tuscan. Under the Merger Agreement, all of the equity interests of Microvast will be converted into an aggregate of 210,000,000 shares of common stock (“closing shares”). The Microvast shareholders and the investors in Microvast’s majority-owned subsidiary, Microvast Power System (Houzhou) Co. Ltd. (“MPS”), will also have the ability to earn an additional 20,000,000 shares of common stock (“earnout shares”) if the daily volume weighted average price of the common stock is greater than or equal to $18.00 for any 20 trading days within a 30 trading day period (or a change of control occurs that results in the holders of common stock receiving a per share price equal to or in excess of $18.00), during the period commencing on the closing date and ending on the third anniversary of the closing date. Concurrently with the execution of the Merger Agreement, Tuscan and Microvast will jointly acquire 100% ownership of MPS and will discharge certain convertible loans of MPS. The Merger will be accounted for as a reverse recapitalization in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Under this method of accounting, Tuscan will be treated as the “acquired” company for accounting purposes and the Business Combination will be treated as the equivalent of Microvast issuing stock for the net assets of Tuscan, accompanied by a recapitalization. The net assets of Tuscan will be stated at historical cost, with no goodwill or other intangible assets recorded. Additionally, the Merger Agreement provides that Tuscan will issue an aggregate of 6,736,111 shares of common stock upon conversion (the “Bridge Notes Conversion”) of an aggregate of $57,500,000 outstanding promissory notes issued by Microvast. Further, on February 1, 2021, Tuscan, the Sponsor, Microvast and certain stockholders of Tuscan entered into the Sponsor Support Agreement (the “Sponsor Support Agreement”), pursuant to which the Sponsor and certain officers and directors of Tuscan (collectively, the “Sponsor Group”) agreed, among other things, to vote all equity interests of Tuscan held by such member of the Sponsor Group in favor of the approval and adoption of the proposed business combination with Microvast. Additionally, such members of the Sponsor Group have agreed not to (a) transfer any of their equity interests in the Company (or enter into any arrangement with respect thereto) other than as set forth therein or (b) exercise any conversion rights of any equity interests held by such member of the Sponsor Group in connection with the approval of the proposed business combination. The Sponsor also agreed that, to the extent that certain expenses of Tuscan are in excess of $46,000,000 (unless such expenses shall have been approved by Microvast), the Sponsor will either (i) pay any such excess amount in cash or (ii) forfeit to Tuscan such number of shares of common stock held by the Sponsor that would have a value equal to such excess. The Sponsor also agreed to amend the escrow agreement to make certain adjustments to the terms of the escrow of its shares of common stock as set forth in the Sponsor Support Agreement. Contemporaneously with the execution of the Merger Agreement, certain investors entered into subscription agreements (the “Subscription Agreements”), pursuant to which such investors subscribed for an aggregate value of $482,500,000, representing 48,250,000 shares of Tuscan common stock at a purchase price of $10.00 per share in a private placement (the “PIPE Financing”) to be consummated immediately prior to the consummation of the Transactions. Affiliates of InterPrivate, a co-sponsor of Tuscan, subscribed to purchase 6.5 million shares in the PIPE Financing for an aggregate purchase price of $65 million. Immediately following the Closing, the former equityholders of Microvast will hold approximately 69.9% of the issued and outstanding shares of common stock and the current stockholders of Tuscan will hold approximately 9.2% of the issued and outstanding shares of common stock, which pro forma ownership (1) assumes no holder of the common stock sold in Tuscan’s initial public offering (such persons, the “Public Stockholders”) exercises its conversion rights in connection with the business combination, and (2) reflects the issuance of an aggregate of 48,250,000 shares of Common Stock in the PIPE Financing and 6,736,111 shares of common stock in the Bridge Notes Conversion, but does not include the effect of any other financing of Tuscan. If the maximum number of Public Shares are converted into cash such that Microvast does not have the right to terminate the Merger Agreement (i.e., Tuscan has at least $5,000,001 of net tangible assets immediately prior to or upon consummation of the business combination), such percentages will be approximately 76.8% and 0.2%, respectively. Consummation of the proposed business combination is subject to customary conditions and covenants of the respective parties, including approval of Tuscan’s stockholders and Tuscan having available cash of at least $250,000,000. Extension Amendment On March 12, 2021, Tuscan filed a preliminary proxy statement seeking approval from its stockholders to amend Tuscan’s charter to extend the date by which Tuscan is required to complete its initial business combination from April 30, 2021 to July 31, 2021 and to hold an annual meeting for the election of directors in accordance with Nasdaq listing rules. Nasdaq Compliance On January 6, 2021, we received a notice from the Listing Qualifications Department of The Nasdaq Stock Market stating that we failed to hold an Annual Meeting of stockholders within 12 months after our fiscal year ended December 31, 2019, as required by Nasdaq Listing Rule 5620(a). In accordance with Nasdaq Listing Rule 5810(c)(2)(G), we submitted a plan to regain compliance on February 4, 2021. Nasdaq accepted our plan and granted us an extension through June 29, 2021 to hold an annual meeting. Nasdaq’s decision is subject to certain conditions, including that we provide periodic updates with respect to our proposed business combination with Microvast. Loan Commitment On February 12, 2021, the Sponsor extended a loan to Tuscan in the aggregate principal amount totaling $1.2 million, of which $400,000 was drawn upon on such date. This loan was in addition to the previous $200,000 drawn upon the $300,000 convertible note that was committed by the Sponsor on April 21, 2020. As a result of the February 12, 2021 commitment, the Sponsor had committed to Tuscan a total of $1.5 million, of which a total of $600,000 has been drawn upon, with $400,000 of the drawn amount pursuant to the February 12, 2021 note. The Sponsor intends to convert the $1.5 million total loan balance into 150,000 Units immediately prior to the closing of the proposed business combination with Microvast. Such units will have terms identical to the terms of the Company’s Private Units and will consist of (i) 150,000 shares of common stock and (ii) warrants to purchase 150,000 shares of common stock at an exercise price of $11.50 per share, subject to adjustment.
