Note 1 — Description of Organization and Business Operations

Organization and General

Trine Acquisition Corp. (the "Company") is a blank check company incorporated in Delaware on September 26, 2018. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the "Initial Business Combination"). The Company is an "emerging growth company," as defined in Section 2(a) of the Securities Act of 1933, as amended, (the "Securities Act"), as modified by the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act").

As of December 31, 2019, the Company had not commenced any operations. All activity for the period from September 26, 2018 (inception) through December 31, 2019 relates to the Company's formation, the initial public offering (the "Initial Public Offering"), which is described below, and identifying a target business for a Business Combination. The Company will not generate any operating revenues until after the completion of its Initial Business Combination, at the earliest. The Company generates non-operating income in the form of interest income on cash and marketable securities from the proceeds derived from the Initial Public Offering.

Sponsor and Initial Public Offering

The registration statements for the Company's Initial Public Offering were declared effective on March 14, 2019. On March 19, 2019, the Company consummated the Initial Public Offering of 26,100,000 units (the "Units") at $10.00 per Unit, generating gross proceeds of $261,000,000, which is described in Note 3.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 7,720,000 warrants (the "Private Placement Warrants") at a price of $1.00 per Unit in a private placement to the Company's sponsor, Trine Sponsor IH, LLC, a Delaware limited liability company (the "Sponsor"), generating gross proceeds of $7,720,000, which is described in Note 4.

On March 29, 2019, in connection with the underwriters' election to fully exercise their over-allotment option, the Company sold an additional 3,915,000 Units at $10.00 per Unit and sold an additional 783,000 Private Placement Warrants at $1.00 per Private Placement Warrant, generating total gross proceeds of $39,933,000. Following such closing, an additional $39,150,000 of net proceeds ($10.00 per Unit) was deposited in the Trust Account, resulting in $300,150,000 ($10.00 per Unit) held in the Trust Account.

Transaction costs amounted to $17,082,640, consisting of $6,003,000 of underwriting fees, $10,505,250 of deferred underwriting fees and $574,390 of other offering costs. In addition, as of December 31, 2019, cash of $138,533 was held outside of the Trust Account (as defined below) and is available for working capital purposes.

The Trust Account

Following the closing of the Initial Public Offering, an amount of $300,150,000 ($10.00 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Private Placement Warrants was placed in a trust account (the "Trust Account"), and invested only in U.S. government treasury bills with a maturity of one hundred eighty (180) days or less or in money market funds that meet certain conditions under Rule 2a-7 under the Investment Company Act of 1940 and that invest only in direct U.S. government obligations. Funds will remain in the Trust Account until the earlier of (i) the consummation of the Initial Business Combination or (ii) the distribution of the Trust Account proceeds as described below. The remaining proceeds held outside the Trust Account may be used to pay for business, legal and accounting due diligence on prospective acquisitions and continuing general and administrative expenses.

The Company's amended and restated certificate of incorporation provides that, other than the withdrawal of interest to pay taxes, if any, none of the funds held in the Trust Account will be released until the earlier of: (i) the completion of the Initial Business Combination; (ii) the redemption of any shares of Class A common stock included in the Units (the "Public Shares" ) sold in the Initial Public Offering that have been properly tendered in connection with a stockholder vote to amend the Company's certificate of incorporation to modify the substance or timing of its obligation to redeem 100% of the Public Shares if it does not complete the Initial Business Combination by March 19, 2021 (the "Combination Period"); and (iii) the redemption of 100% of the Public Shares if the Company is unable to complete an Initial Business Combination within the Combination Period (subject to the requirements of law). The proceeds deposited in the Trust Account could become subject to the claims of the Company's creditors, if any, which could have priority over the claims of the Company's public stockholders.

Initial Business Combination

The Company's management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating an Initial Business Combination. The Initial Business Combination must be with one or more target businesses that together have an aggregate fair market value of at least 80% of the assets held in the Trust Account (excluding deferred underwriting fees and taxes payable) at the time of the agreement to enter into the Initial Business Combination. Furthermore, there is no assurance that the Company will be able to successfully effect an Initial Business Combination. 

NYSE rules require that the Company must complete one or more business combinations having an aggregate fair market value of at least 80% of the value of the assets held in the Trust Account (excluding deferred underwriting fees and taxes payable) at the time of the signing a definitive agreement in connection with an Initial Business Combination. The Company's board of directors will make the determination as to the fair market value of the Initial Business Combination. If the Company's board of directors is not able to independently determine the fair market value of an Initial Business Combination, then Company will obtain an opinion from an independent investment banking firm or another independent entity that commonly renders valuation opinions with respect to the satisfaction of such criteria. While the Company considers it unlikely that its board of directors will not be able to make an independent determination of the fair market value of an Initial Business Combination, it may be unable to do so if it is less familiar or experienced with the business of a particular target or if there is a significant amount of uncertainty as to the value of a target's assets or prospects.

The Company, after signing a definitive agreement for an Initial Business Combination, will either (i) seek stockholder approval of the Initial Business Combination at a meeting called for such purpose in connection with which stockholders may seek to redeem their Public Shares, regardless of whether they vote for or against the Initial Business Combination, for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination, including interest but less taxes payable, or (ii) provide stockholders with the opportunity to sell their Public Shares to the Company by means of a tender offer (and thereby avoid the need for a stockholder vote) for an amount in cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination, including interest but less taxes payable. The decision as to whether the Company will seek stockholder approval of the Initial Business Combination or will allow stockholders to sell their Public Shares in a tender offer will be made by the Company, solely in its discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would otherwise require the Company to seek stockholder approval, unless a vote is required by law or under NYSE rules. If the Company seeks stockholder approval, it will complete its Initial Business Combination only if a majority of the outstanding shares of common stock voted are voted in favor of the Initial Business Combination. However, in no event will the Company redeem its Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001 upon consummation of the Initial Business Combination. In such case, the Company would not proceed with the redemption of its Public Shares and the related Initial Business Combination, and instead may search for an alternate Initial Business Combination.

If the Company holds a stockholder vote or there is a tender offer for shares in connection with an Initial Business Combination, a public stockholder will have the right to redeem its Public Shares for an amount in cash equal to its pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination, including interest but less taxes payable.

Pursuant to the Company's amended and restated certificate of incorporation, if the Company is unable to complete the Initial Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, subject to lawfully available funds therefor, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to the Company to pay taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish public stockholders' rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company's remaining stockholders and the Company's board of directors, dissolve and liquidate, subject in each case to the Company's obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. The Sponsor and the Company's officers and directors entered into a letter agreement (the "Letter Agreement") with the Company, pursuant to which they agreed to waive their rights to liquidating distributions from the Trust Account with respect to any Founder Shares (as defined below) held by them if the Company fails to complete the Initial Business Combination within the Combination Period. However, if the Sponsor or any of the Company's directors, officers or affiliates acquire shares of Class A common stock during or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such shares if the Company fails to complete the Initial Business Combination within the prescribed time period.

In the event of a liquidation, dissolution or winding up of the Company after an Initial Business Combination, the Company's stockholders are entitled to share ratably in all assets remaining available for distribution to them after payment of liabilities and after provision is made for each class of stock, if any, having preference over the common stock. The Company's stockholders have no preemptive or other subscription rights. There are no sinking fund provisions applicable to the common stock, except that the Company will provide its stockholders with the opportunity to redeem their Public Shares for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account, upon the completion of the Initial Business Combination, subject to the limitations described herein.
