Explanatory Note

This Amendment No. 2 to Schedule 13D (this “Amendment No. 2”) is being filed to amend the statement on Schedule 13D filed by Douglas Campbell (the “Reporting Person”) on December 15, 2021 (the “Original Statement”), as amended by Amendment No. 1 to the Original Statement filed on January 13, 2022, (as so amended, the “Schedule 13D”) and relates to shares of common stock, par value $0.0001 per share (the “Common Stock”), of Solid Power, Inc. (f/k/a Decarbonization Plus Acquisition Corporation III), a Delaware corporation (the “Issuer”).

The Schedule 13D is hereby amended and supplemented as detailed below, and, except as amended and supplemented hereby, the Schedule 13D remains in full force and effect. All capitalized terms not otherwise defined herein shall have the meaning ascribed to such terms in the Schedule 13D.

Item 3. Source and Amount of Funds or Other Consideration.

Item 3 of the Schedule 13D is hereby amended and restated in its entirety to read as follows:

Pursuant to the Business Combination Agreement, dated June 15, 2021 (as amended, the “Business Combination Agreement”), by and among the Issuer, DCRC Merger Sub Inc., a Delaware corporation and wholly owned subsidiary of the Issuer (“Merger Sub”), and Solid Power Operating, Inc., a Colorado corporation (f/k/a Solid Power, Inc., “Legacy Solid Power”), a business combination between the Issuer and Legacy Solid Power was effected through the merger of Merger Sub with and into Legacy Solid Power, with Legacy Solid Power surviving as the surviving company and as a wholly owned subsidiary of Issuer (the “Merger” and, collectively with the other transactions described in the Business Combination Agreement, the “business combination”). The business combination closed on December 8, 2021 (the “Closing”).

In connection with the Closing, and subject to the terms and conditions of the Business Combination Agreement, each outstanding share of Legacy Solid Power’s common stock was canceled and converted into the right to receive the number of shares of the Issuer’s Common Stock equal to such number of shares multiplied by approximately 3.182 (the “Exchange Ratio”), and each outstanding Legacy Solid Power option was converted into an Issuer option based on the Exchange Ratio applicable to shares of Legacy Solid Power common stock. Following the Closing, each exchanged Legacy Solid Power option continued to be governed by the same terms and conditions (including vesting and exercisability terms) as were applicable to the corresponding Legacy Solid Power option immediately prior to the Closing.

In connection with the Closing, the Reporting Person tendered (i) 2,100,000 shares of Legacy Solid Power common stock in exchange for 6,682,160 shares of Common Stock and (ii) fully vested options to purchase 1,600,000 shares of Legacy Solid Power common stock in exchange for options to purchase 5,091,169 shares of Common Stock (the “Exchanged Option”). The Reporting Person also tendered unvested options to purchase shares of Legacy Solid Power common stock, which resulted in the Reporting Person owning options to an additional 477,296 shares of Common Stock, which options are subject to certain ongoing vesting conditions.

On January 12, 2022, the Reporting Person exercised the Exchanged Option and acquired 5,091,169 shares of Common Stock.

On June 27, 2022, the Reporting Person transferred 162,338 shares of Common Stock as a gift to The University of New Mexico Foundation, Inc.

The information set forth in or incorporated by reference into Items 4, 5 and 6 of this Schedule 13D is hereby incorporated by reference in its entirety into this Item 3.

Item 5. Interest in Securities of the Issuer.

Item 5 of the Schedule 13D is hereby amended and restated in its entirety to read as follows:

(a) As of the date of this Amendment No. 2, the Reporting Person beneficially owns an aggregate of 11,729,615 shares of Common Stock, or approximately 6.7% of the Issuer’s Common Stock. The beneficial ownership percentages used in this Schedule 13D are calculated based on a total of 174,074,861 shares of Common Stock outstanding as of May 6, 2022, which equals the number of shares of Common Stock as set forth in the Issuer’s Form 10-Q filed with the Securities and Exchange Commission on May 11, 2022, plus 118,624 shares of Common Stock deemed to be beneficially owned by Mr. Campbell that are issuable upon exercise of options scheduled to vest within 60 days of the date of this Amendment No. 2 and held by Mr. Campbell.

(b) The Reporting Person has sole voting and dispositive power with respect to 11,610,991 shares of Common Stock and 118,624 shares of Common Stock issuable upon exercise of options that are scheduled to vest within 60 days of the date of this Amendment No. 2.

(c) Except as described in Items 3 and 4 of this Schedule 13D, which descriptions are incorporated herein by reference, the Reporting Person has not effected any transactions in the Common Stock during the past 60 days.

(d) Except as disclosed in Item 2, no person is known to the Reporting Person to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, any securities covered by this Schedule 13D.

(e) Not Applicable.
