(1) As described in the issuer's registration statement on Form S-1 (File No. 333-229853) under the heading "Description of Securities--Founder Shares," the shares of Class B common stock will automatically convert into shares of Class A common stock of the issuer at the time of the issuer's initial business combination or earlier at the option of the holder, in each case, on a one-for-one basis, subject to adjustment for stock splits, stock dividends, reorganizations, recapitalizations and the like, and certain anti-dilution rights.
(2) These shares represent Class B common stock held by Trine Sponsor IH, LLC (the "Sponsor"), which were originally acquired pursuant to a subscription agreement by and between Trine Sponsor, LLC, the prior sponsor of the issuer, and the issuer and subsequently transferred by Trine Sponsor, LLC to the Sponsor. The Class B common stock owned by the Sponsor includes up to 978,750 shares that are subject to forfeiture in the event the underwriters of the issuer's initial public offering do not exercise in full their over-allotment option as described in the issuer's registration statement.
(3) Robin Trine Holdings, LLC ("RTH") and HPS Investment Partners, LLC ("HPS") are the members of the Sponsor, and as such each of HPS and RTH has appointed a member to the board of the Sponsor, which board has voting and investment discretion with respect to the common stock held of record by the Sponsor. Leo Hindery, Jr., Chairman and Chief Executive Officer of the issuer, is the managing member of RTH. Based on the foregoing, Mr. Hindery, RTH and HPS may be deemed to have shared beneficial ownership of the common stock held directly by the Sponsor. Each such entity or person disclaims any beneficial ownership of the reported shares other than to the extent of any pecuniary interest they may have therein, directly or indirectly.
