Explanatory Note

The Reporting Persons (as defined below) previously filed a Schedule 13G pursuant to Rule 13d-1(d) under the Securities Exchange Act of 1934, as amended (the “Act”), with respect to their beneficial ownership of Common Stock (as defined below) of the Issuer (as defined below). In connection with the closing of the Business Combination (as defined below) and the transactions contemplated thereby, the Reporting Persons will now report their beneficial of such securities on a Schedule 13D.

Item 1.

Security and Issuer.

This statement on Schedule 13D (the “Schedule 13D”) is being filed with respect to the common stock, par value $0.0001 per share (the “Common Stock”), of Spectaire Holdings Inc., a Delaware corporation (f/k/a Perception Capital Corp. II) (the “Issuer”), whose principal executive offices are located at 155 Arlington St., Watertown, MA 02472.

Item 2.

Identity and Background.

(a-c, f) This Schedule 13D is filed jointly on behalf of Perception Capital Partners II LLC, a Delaware limited liability company (the “Sponsor”); Perception Capital Partners LLC, a Delaware limited liability company (“PCP”); Northern Pacific Group L.P., a Delaware limited partnership (“NPG”); Scott Honour, a United States citizen (“Mr. Honour”); and Marcy Haymaker, a United States citizen (“Ms. Haymaker”) (collectively, the “Reporting Persons” and each, a “Reporting Person”). The Sponsor is controlled by PCP, which is controlled by NPG, which is controlled by Mr. Honour and Ms. Haymaker. As such, each of PCP, NPG, Mr. Honour and Ms. Haymaker may be deemed to beneficially own the Common Stock held by the Sponsor by virtue of their shared control over the Sponsor.

The Sponsor is an entity formed for the purpose of investing in securities of the Issuer. The principal business of each of PCP and NPG is to manage the Sponsor and various other entities created for investment purposes. The principal business or occupation of each of Mr. Honour and Ms. Haymaker is to manage and oversee the aforementioned investments and investment activities of the Sponsor, PCP and NPG.

The principal business address of each of the Reporting Persons is 3109 W 50th St., #207, Minneapolis, MN 55410.

(d) None of the Reporting Persons has, during the last five years, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

(e) None of the Reporting Persons has, during the last five years, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and, as a result of such proceeding, was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3.

Source and Amount of Funds or Other Consideration.

In January 2021, the Sponsor paid an aggregate of $25,000 to cover certain expenses on behalf of the Issuer prior to the consummation of the Issuer’s initial public offering in exchange for the issuance of 7,187,500 Class B ordinary shares, $0.0001 per share (the “Class B Ordinary Shares”), of the Issuer. In April 2021, the Sponsor transferred 30,000 Class B Ordinary Shares to each of the Issuer’s then independent directors, or 90,000 Class B Ordinary Shares in the aggregate, and in August 2021, the Sponsor surrendered for no consideration 1,437,500 Class B Ordinary Shares, resulting in an effective purchase price of approximately $0.04 per Class B Ordinary Share. As a result of the foregoing transactions, the Sponsor held an aggregate of 5,660,000 Class B Ordinary Shares. Simultaneously with the closing of the Issuer’s initial public offering, the Sponsor purchased warrants of the Issuer in a private placement (the “Private Placement Warrants”), at a price of $1.00 per warrant.

On October 19, 2023, pursuant to that certain Agreement and Plan of Merger, dated as of January 16, 2023 (the “Merger Agreement”), by and among the Issuer, Perception Spectaire Merger Sub Corp., a wholly owned subsidiary of the Issuer (“Merger Sub”), and Spectaire Inc. (“Spectaire”), Merger Sub merged with and into Spectaire, with Spectaire as the surviving corporation and direct wholly-owned subsidiary of the Issuer (the “Business Combination”). In connection with the Business Combination, the Issuer changed its name to “Spectaire Holdings Inc.”

In connection with the Business Combination, the Issuer domesticated as a Delaware corporation (the “Domestication”). As a result of the Domestication, the 5,660,000 Class B ordinary shares held by the Sponsor converted, on a one-for-one basis, into 5,660,000 shares of Common Stock. To facilitate fundraising efforts of the Issuer in connection with the Business Combination, the Sponsor agreed to forfeit for cancellation 585,000 shares of Common Stock upon the closing of the Business Combination, pursuant to a letter agreement, dated October 4, 2023, between the Sponsor and the Issuer (the “Letter Agreement”). Following the closing of the Business Combination on October 19, 2023 (the “Closing”), and pursuant to the terms of the Letter Agreement, the Sponsor directly held 5,075,000 shares of Common Stock and 10,050,000 Private Placement Warrants, which become exercisable 30 days after the Closing.

Item 4.

The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Any actions the Reporting Persons might undertake with respect to securities of the Issuer may be made at any time and from time to time without prior notice and will be dependent upon the Reporting Persons’ review of numerous factors, including, but not limited to, an ongoing evaluation of the Issuer’s business, financial condition, operations and prospects; price levels of the Issuer’s securities; general market, industry and economic conditions; the relative attractiveness of alternative business and investment opportunities; and other future developments.
