Trine Acquisition Corp, which completed its initial public offering in 2019 and subsequently merged with additive manufacturing company Desktop Metal, Inc. to form NYSE-listed DM, filed an S-4/A amendment with the Securities and Exchange Commission in October 2021. Sponsored by Trine Capital, the blank-check vehicle targeted the industrial technology and advanced manufacturing sector before completing its de-SPAC transaction. The S-4/A, an amendment to a previously filed registration statement, reflects continued corporate activity at the combined entity in the period following the business combination.
