Explanatory Note

This Amendment No. 1 to Schedule 13D (“Amendment No. 1”) is being filed on behalf of the undersigned, Craig Evans and Dr. Yang (Julia) Song (the “Reporting Persons,” and each, a “Reporting Person”), to amend the Schedule 13D filed with the Securities and Exchange Commission on July 13, 2023 ( as amended, the “Schedule 13D”). This Amendment No. 1 is being filed to disclose that the Reporting Persons have ceased to be the beneficial owner of more than five percent of the outstanding shares of Common Stock of the Issuer. This Amendment No. 1 is the final amendment to the Schedule 13D and constitutes an exit filing for the Reporting Persons. Except as specifically amended and supplemented by this Amendment No. 1, the Schedule 13D remains in full force and effect. All capitalized terms contained herein but not otherwise defined shall have the meaning ascribed to such terms in the Schedule 13D. This Amendment No. 1 constitutes a late filing due to administrative error.

Item 2. Identity and Background.

Item 2 of the Schedule 13D is hereby amended and supplemented as follows:

(c) The present principal occupation of each Reporting Person is as follows: Craig Evans, retired. Dr. Julia Song, member of the Advisory Board of Materials Discovery Research Institute (MDRI) and industrial expert to the MRS Energy & Sustainability Editorial Advisory Board, Materials Research Society, 506 Keystone Drive, Warrendale, PA 15086-7537.

Item 4. Purpose of Transaction.

Item 4 of the Schedule 13D is hereby amended and supplemented as follows:

Dr. Song resigned from her position as Chief Technology Officer of the Issuer on June 1, 2024, and consequently no longer has influence over the corporate activities of the Issuer.

Item 5. Interest in Securities of the Issuer.

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

The responses of the Reporting Persons to rows (7) through (13) of the cover pages and Items 2, 3, 4 and 6 of this Amendment No. 1 are incorporated into this Item 5 by reference.

(a)and (b) As of the date hereof, the Reporting Persons beneficially own 334,707 shares of Common Stock representing approximately 2.8% of the issued and outstanding shares of the Issuer’s Common Stock, consisting of: (i) 291,342 shares of Common Stock held by Mr. Evans, (ii) 7,026 shares of Common Stock held by Dr. Julia Song, (iii) 14,006 shares of Common Stock underlying stock options held by Mr. Evans exercisable within 60 days of the date hereof and (iv) 22,333 shares of Common Stock underlying stock options held by Dr. Song exercisable within 60 days of the date hereof. Mr. Evans and Dr. Song are married and may be deemed to share voting and dispositive power over shares held of record by each other

(d) To the knowledge of the Reporting Persons, no other person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, any shares of Common Stock beneficially owned by the Reporting Persons.

(e) As a result of the issuance of shares of Common Stock to Honeywell ACS Ventures LLC (as described in the Issuer’s Form 8-K filed on September 25, 2023), the Reporting Persons ceased to beneficially own in excess of 5% of the Issuer’s Common Stock on September 21, 2023. However, the Reporting Persons deem May 15, 2024 to be the relevant date of event for this final amendment to the Schedule 13D, as it is the date on which a material change occurred in the number of shares of the Issuer’s Common Stock beneficially owned or deemed to be beneficially owned by the Reporting Persons, as the case may be, since the filing of the initial Schedule 13D.
