Solid Power, Inc. Announces Full Year 2021 Financial Results

Financial results and business update call scheduled for 5:00 PM ET today

LOUISVILLE, Colo., March 22, 2022 – Solid Power, Inc. (Nasdaq: SLDP), an industry-leading developer of all-solid-state battery cells for electric vehicles, today announced its financial results for the full year ended December 31, 2021.

Recent business highlights:

• The completion of Solid Power’s business combination on December 8, 2021, resulting in net cash proceeds of $495 million to fund its product development and strategic growth plans

• Completion of all planned 2021 milestones, including the start of production of 20 Ah high-content silicon anode cells (“Silicon EV Cells”) on the Company’s pilot production line

• Partnership with leading lithium-ion cell producer SK Innovation Co., Ltd. to validate that Solid Power’s all-solid-state cell designs and production processes are scalable and to produce EV-scale cells as part of the Company’s automotive qualification process

• Nearing completion of first EV-scale pilot manufacturing line

• Continued progress on electrolyte production facility, which will support the Company‘s EV cell line and automotive qualification endeavors

“2021 was a transformational year for Solid Power, highlighted by key operational and strategic successes that accelerated the company’s growth potential,” said Doug Campbell, Chief Executive Officer of Solid Power. “Having secured substantial funding, we are focused on executing on our development roadmap while putting into place key operating capabilities to produce full-scale all-solid-state EV battery cells for our partner’s automotive qualification processes. We are also strengthening our team and processes to ensure our governance and operations reflect our high standards while we deliver value to our stakeholders.”

Campbell continued, “As the pace of EV technology adoption continues to increase, we are seeing battery customers intensify their interest and commitment to our all-solid-state value proposition. To meet the anticipated demand, we are accelerating investments in our operations, production equipment, and technology development. While these actions will not speed up our timeline to complete automotive qualification, we believe they can lower execution risk associated with our product development and associated revenue plan. We expect these efforts will also enhance cooperation with our current partners and give us the flexibility to onboard additional partners as we see fit.”

Solid Power is focused on delivering the following key milestones for 2022:

• Delivering 2 Ah and 20 Ah Silicon EV Cells to automotive partners

• Completing pilot EV line and commencing cell production

• Completing construction of electrolyte production facility

• Delivering EV-scale Silicon EV Cells to our automotive partners by the end of the year
