Introductory Note

This Amendment No. 1 to Schedule 13D is filed by and on behalf of each of the Reporting Persons to amend and supplement the Schedule 13D related to the Class A Common Stock, par value $0.0001 per share, of Decarbonization Plus Acquisition Corporation III (the “Issuer”), previously filed by the Reporting Persons with the Securities and Exchange Commission (the “SEC”) on August 2, 2021 (as amended, the “Schedule 13D”). Each capitalized term used and not defined herein shall have the meaning assigned to such term in the Schedule 13D. Except as provided herein, each Item of the Schedule 13D remains unchanged.

Item 5. Interest in Securities of the Issuer

Item 5 of the Schedule 13D is hereby amended and supplemented as follows:

(a), (b) Based upon the Issuer’s Form S-4/A filed with the SEC on November 2, 2021, there were 43,710,000 Common Shares issued and outstanding as of October 29, 2021. The 1,791,470 Common Shares beneficially owned by Valence (the “Valence Shares”) represent approximately 4.09% of the Common Shares issued and outstanding. The 393,087 Common Shares beneficially owned by Oculus (the “Oculus Shares”) represent approximately 0.89% of the Common Shares issued and outstanding.

DESCO LLC, as the manager of Oculus and Valence, may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) the Valence Shares and the Oculus Shares (collectively, the “Subject Shares”).

DESCO LP, as the investment adviser of Valence and Oculus, may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) the Subject Shares. On November 10, 2021, the Reporting Persons beneficially owned 4.99% of the outstanding shares. Neither DESCO LP nor DESCO LLC owns any of the Subject Shares directly, and each of DESCO LP and DESCO LLC disclaims beneficial ownership of the Subject Shares.

David E. Shaw does not own any shares directly. By virtue of David E. Shaw’s position as President and sole shareholder of DESCO Inc., which is the general partner of DESCO LP, which in turn is the investment adviser of Valence and Oculus, and by virtue of David E. Shaw’s position as President and sole shareholder of DESCO II Inc., which is the managing member of DESCO LLC, which in turn is the manager of Valence and Oculus, David E. Shaw may be deemed to have the shared power to vote or direct the vote of, and the shared power to dispose or direct the disposition of, the Subject Shares as described above and, therefore, David E. Shaw may be deemed to be the beneficial owner of the Subject Shares. David E. Shaw disclaims beneficial ownership of the Subject Shares.

As of November 10, 2021, neither any Reporting Person nor, to the best knowledge of any Reporting Person, any of the persons set forth in Item 2, owned any Common Shares other than those set forth in Item 5.

(c) The trading dates, number of Common Shares purchased or sold, and the price per share for all transactions by the Reporting Persons (or certain entities affiliated with the Reporting Persons) in the Common Shares from September 11, 2021 through November 10, 2021, which were all brokered transactions, are set forth below:

Name	Date	Price per Share1	Number of Shares Purchased/(Sold)
Oculus	10/27/2021	$10.53942	(5,200)
Valence	10/27/2021	$10.54112	(15,505)
Oculus	10/28/2021	$11.10153	(19,689)
Valence	10/28/2021	$11.09284	(63,465)
Oculus	10/29/2021	$11.94085	(31,063)
Oculus	10/29/2021	$12.33376	(848)
Valence	10/29/2021	$11.91157	(120,912)
Valence	10/29/2021	$12.32148	(5,226)
Oculus	11/2/2021	$12.66979	(4,100)
Valence	11/2/2021	$12.670910	(12,135)
Oculus	11/5/2021	$11.4207	(41,855)
Valence	11/5/2021	$11.4207	(190,745)
Oculus	11/8/2021	$12.2862	(41,855)
Valence	11/8/2021	$12.2862	(190,745)
Oculus	11/9/2021	$11.6413	(41,855)
Valence	11/9/2021	$11.6413	(190,745)
Oculus	11/10/2021	$11.3084	(38,148)
Valence	11/10/2021	$11.3084	(173,852)

(e) On November 8, 2021, Valence ceased to be the beneficial owner of more than 5% of the outstanding Common Shares. On November 10, 2021, DESCO LLC, DESCO LP, and David E. Shaw ceased to be beneficial owners of more than 5% of the outstanding Common Shares.

¹ Where weighted average price is used for the reported transactions, the Reporting Persons undertake to provide upon request by the SEC, full information regarding the number of shares purchased or sold at each separate price.

² A weighted average price based on prices ranging from $10.40 to $10.65.
