Trine Warrants

In Trine’s initial public offering, it sold units at a price of $10.00 per unit, which consisted of one share of Common Stock, $0.0001 par value, and one-half of a redeemable warrant (each, a “Public Warrant”). Each whole Public Warrant entitles the holder to purchase one share of Common Stock at a price of $11.50 per share and became exercisable as of 30 days from the date of the Business Combination. Unless earlier redeemed, the Public Warrants will expire five years from the completion of the Business Combination. The Company may redeem the outstanding Public Warrants in whole and not in part at a price of $0.01 per Public Warrant upon a minimum of 30 days’ prior written notice of redemption, and only in the event that the last sale price of the Company’s Common Stock is at least $18.00 per share for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which notice of redemption is given. If the Company redeems the Public Warrants as described above, it will have the option to require all Public Warrant holders that wish to exercise to do so on a “cashless basis”. On February 26, 2021, the Company delivered a notice to redeem all of its outstanding Public Warrants that remain unexercised at 5:00 p.m. New York City time on March 29, 2021. During the three months ended March 31, 2021, Public Warrants for 14,840,589 shares of the Company’s Common Stock were exercised for cash, resulting in the Company receiving net proceeds of $170.7 million. On March 29, 2021, the 166,905 outstanding Public Warrants were redeemed by the Company for $0.01 per Public Warrant. As of March 31, 2021, none of the Public Warrants remain outstanding.

The Warrant Agreement, dated as of March 14, 2019, by and between the Company and Continental Stock Transfer & Trust Company also obligated the Company to use its best efforts to file with the SEC a registration statement for the registration, under the Securities Act of 1933, as amended (the “Securities Act”), of the issuance of the shares of Common Stock issuable upon exercise of the Public Warrants, and to cause the same to become effective and remain effective while the Public Warrants remain outstanding. On February 4, 2021, the Company’s registration statement covering such shares became effective.

Simultaneously with the consummation of Trine’s initial public offering, Trine Sponsor IH, LLC (the “Sponsor”) purchased an aggregate of 8,503,000 warrants to purchase one share of Common Stock at an exercise price of $11.50 (the “Private Placement Warrants”) at a price of $1.00 per warrant ($8,503,000) in the aggregate in a private placement.

The Private Placement Warrants are identical to the Public Warrants except that the Private Placement Warrants are not redeemable by Desktop Metal, and may be exercised for cash or on a cashless basis so long as they are held by the Sponsor or any of its permitted transferees. Additionally, pursuant to the terms of the amended and restated registration rights agreement entered in connection with the Business Combination, the Sponsor had the right to have the resale of the shares of Common Stock acquired upon

exercise of the Private Placement Warrants registered under the Securities Act. On February 4, 2021, the Company’s registration statement covering such shares became effective.

On February 24, 2020, Trine issued an unsecured promissory note (the “2020 Note”) to the Sponsor. The 2020 Note bore no interest and was repayable in full upon consummation of the Business Combination. The Sponsor had the option to convert any unpaid balance of the 2020 Note into warrants equal to the principal amount of the 2020 Note so converted divided by $1.00. Upon closing of the Business Combination, the 2020 Note was converted into a Private Placement Warrant for 1,500,000 shares of Common Stock, with an exercise price of $11.50. The terms of these warrants are identical to the terms of the Private Placement Warrants. Pursuant to the terms of the amended and restated registration rights agreement entered in connection with the Business Combination, the Sponsor had the right to have the resale of the shares of Common Stock acquired upon exercise of such warrant registered under the Securities Act. On February 4, 2021, the Company’s registration statement covering such shares became effective.

The Company’s Private Placement Warrants are classified as liabilities, and are measured at fair value through earnings. During the three months ended March 31, 2021, the Company recorded a $56.6 million loss related to the change in fair value of the Private Placement Warrants, which were remeasured through the date of each exercise, calculated using the Black-Scholes warrant pricing model with the following assumptions:

During the three months ended March 31, 2021, all of the Private Placement Warrants were exercised on a cashless basis, and an aggregate of 5,850,346 shares of the Company’s Common Stock were issued in connection with these exercises. As of March 31, 2021, none of the Private Placement Warrants remain outstanding.
