PURE-PLAY ADDITIVE MANUFACTURING 2.0 COMPANY

Desktop Metal Completes Its Business Combination with Trine Acquisition Corp. as Trading Begins Today on the NYSE under the Ticker Symbol “DM”

BURLINGTON, MA (December 10, 2020) – Desktop Metal, Inc. (“Desktop Metal” or the “Company”) a leader in mass production and turnkey additive manufacturing solutions, and Trine Acquisition Corp. (NYSE: TRNE), (“Trine”) a special purpose acquisition company led by Leo Hindery, Jr. and HPS Investment Partners, a global credit investment firm with over $60 billion in assets under management, today announced the completion of their previously announced business combination. The resulting company is named Desktop Metal, Inc. and its common stock and warrants are expected to commence trading on the New York Stock Exchange under the new ticker symbol “DM” and “DM.WT” on December 10, 2020.

The transaction was unanimously approved by the board of directors of Trine and was also approved at a special meeting of Trine’s stockholders on December 8, 2020. As a result of this transaction, Desktop Metal has received approximately $580 million of gross proceeds from Trine’s trust account and concurrent equity private placements.

“Today is an exciting moment and major milestone for our company and for the additive manufacturing (AM) industry at large,” said Ric Fulop, Co-founder and Chief Executive Officer of Desktop Metal. “With a broad portfolio of solutions offering revolutionary ease-of-use and productivity for the AM industry, Desktop Metal is uniquely positioned to disrupt how parts are made across a wide range of industries. The capital raised through our transition to a publicly traded company will accelerate our global go-to-market efforts, enhance our relentless efforts in R&D, and allow us to capitalize on the tremendous growth opportunities we see over the next decade as we integrate industry-leading technology and intellectual property with strong secular growth trends around AM. We are excited to bring Desktop Metal to the public markets as the only pure play Additive Manufacturing 2.0 (AM 2.0) company and offer everyone the opportunity to invest in a company aiming to transform the manufacturing industry.”

Founded in 2015 with a vision to pioneer technology that changes the way parts are produced through AM, Desktop Metal has quickly grown to become a global enterprise offering a diverse suite of AM solutions. Led by an experienced team with deep operational and scientific pedigree, Desktop Metal has distribution in more than 60 countries around the world and adoption from leading companies spanning a broad array of industries, including automotive, consumer products, industrial automation, medical devices, aerospace and defense.

The Company’s product portfolio is anchored by its flagship Production System^TM P-50, which is scheduled to begin volume commercial shipments in the second half of 2021. The P-50 is designed to achieve print speeds up to 100 times those of legacy technologies⁽¹⁾, delivering thousands of parts per day at costs competitive with conventional manufacturing. The recently revealed Production System P-1 leverages the same patent-pending Single Pass Jetting^TM technology as the P-50 and begins initial shipments to customers in Q4 2020. Desktop Metal’s AM 2.0 portfolio also includes Shop System^TM, a mid-volume, flexible manufacturing solution designed for machine shops which began volume manufacturing and global shipments in Q4 2020; Studio System^TM, an office-friendly metal 3D printing system for low-volume production which has been shipping in volume globally since 2018; and Fiber^TM, a continuous fiber composite printer, scheduled to begin volume commercial shipments in Q4 2020.

The AM 2.0 Revolution and Its Impact to Industry 4.0

The AM industry grew at a 20 percent annual compound rate between 2006 and 2016 before accelerating to 25 percent compound annual growth over the last three years, a rate that is expected to continue over the next decade as the market grows from $12 billion in 2019 to an estimated $146 billion in 2030⁽²⁾.

“We believe the AM industry is at a major inflection point and that Desktop Metal is at the forefront of this transformation,” said Fulop. “This market inflection is being driven by the emergence of AM 2.0 a wave of next-generation AM technologies that unlocks throughput, repeatability, and competitive part costs with a focus on making AM an easy to use, economic solution for mass production. These solutions feature key innovations across printers, materials, and software to pull AM into direct competition with conventional processes used to manufacture $12 trillion in goods annually⁽³⁾.”

“Desktop Metal is poised to revolutionize the manufacturing industry by applying transformative AM 2.0 technologies to the products and industries that will drive the economy in the 21st century,” said Leo Hindrey, Jr., Desktop Metal board member and Chairman and CEO of Trine Acquisition Corp. “The company has a distinct first-mover advantage over competitors and the injection of capital from this transaction, a large portion of which will be dedicated to continuous product innovation, will protect and extend this first-mover advantage.”
