This Amendment No. 4 to the joint statement on Schedule 13D with respect to the common stock, par value $0.01 per share (the “Common Stock”), of Natural Gas Services Group, Inc., a Colorado corporation (the “Issuer”), filed by Mill Road Capital III, L.P., a Cayman Islands exempted limited partnership (the “Fund”), Mill Road Capital III GP LLC, a Cayman Islands limited liability company and the sole general partner of the Fund (the “GP”), and Thomas E. Lynch (together with the Fund and the GP, the “Reporting Persons”) on January 4, 2021, as amended by Amendment No. 1 filed by the Reporting Persons on December 23, 2022, as amended by Amendment No. 2 filed by the Reporting Persons on March 10, 2023, and as amended by Amendment No. 3 filed by the Reporting Persons on May 2, 2023 (such joint statement, as so amended and as amended herein, the “Schedule 13D”), amends the Schedule 13D as follows:

1. The first paragraph of Item 2(a) of the Schedule 13D shall hereby be amended and restated in full as follows:

(a) This joint statement on Schedule 13D is being filed by Thomas E. Lynch, Mill Road Capital III GP LLC, a Cayman Islands limited liability company (the “GP”), and Mill Road Capital III, L.P., a Cayman Islands exempted limited partnership (the “Fund”). Each of the foregoing is referred to in this Schedule 13D as a “Reporting Person” and, collectively, as the “Reporting Persons.” Mr. Lynch, Deven Petito and Eric Yanagi are the Management Committee Directors of the GP and, in this capacity, are referred to in this Schedule 13D as the “Managers.” The GP is the sole general partner of the Fund. Mr. Lynch has shared authority to vote and dispose of the shares of Common Stock reported in this Schedule 13D.

2. Item 2(b) of the Schedule 13D shall hereby be amended and restated in full as follows:

(b) The business address of Mr. Lynch, Mr. Petito and Mr. Yanagi, and the address of the principal business and the principal office of the Fund and the GP, is 334 Pemberwick Road, Second Floor, Greenwich, CT 06831.

3. Item 3 of the Schedule 13D shall hereby be amended and restated in its entirety as follows:

The Reporting Persons acquired beneficial ownership of an aggregate of 829,808 shares of Common Stock for $8,181,681.78, using working capital from the Fund and the proceeds of margin loans under margin loan facilities maintained in the ordinary course of business by the Fund with a broker on customary terms and conditions. The purchase price of shares acquired pursuant to the assignment of standard American-style, exchange-traded put options (“Put Options”) is not reduced by the premium received by the Reporting Persons upon sale of the Put Options.

CUSIP No. 63886Q109				Page 6 of 8 Pages

 

4. Paragraphs (a), (b) and (c) of Item 5 of the Schedule 13D shall hereby be amended and restated in full as follows:

(a, b) The percentages of beneficial ownership reported in this Item 5, and on each Reporting Person’s cover page to this Schedule 13D, are based on a total of 12,474,020 shares of the Common Stock issued and outstanding as of November 8, 2024, as reported in the most recent quarterly report of the Issuer on Form 10-Q for the fiscal quarter ended September 30, 2024. All of the share numbers reported below, and on each Reporting Person’s cover page to this Schedule 13D, are as of November 25, 2024, unless otherwise indicated. The cover page to this Schedule 13D for each Reporting Person is incorporated by reference in its entirety into this Item 5(a, b).

The Fund directly holds, and thus has sole voting and dispositive power over, 829,808 shares of Common Stock. The GP, as sole general partner of the Fund, also has sole authority to vote (or direct the vote of), and to dispose (or direct the disposal) of, these shares of Common Stock on behalf of the Fund, and Mr. Lynch has shared authority to vote (or direct the vote of), and to dispose (or direct the disposal) of, these shares on behalf of the GP. Accordingly, each of the Reporting Persons beneficially owns 829,808 shares of Common Stock, or approximately 6.7% of the outstanding shares of Common Stock, and the Reporting Persons beneficially own, in the aggregate, 829,808 shares of Common Stock, or approximately 6.7% of the outstanding shares of Common Stock. Neither of Messrs. Petito nor Yanagi has beneficial ownership of any shares of Common Stock.

(c) Except as otherwise described in this Schedule 13D, no Reporting Person, other than the Fund as set forth in the table below, effected any transaction in shares of Common Stock during the period (the “Reporting Period”) from September 26, 2024 (the date 60 days prior to the filing of this Schedule 13D) to November 25, 2024:

 

Date of Sale		Shares Sold (#)				Sale Price per Share ($)
11/21/2024			55,508				27.0530
11/22/2024			35,094				27.8905
11/25/2024			1,098				27.6840

The above listed transactions were conducted in the ordinary course of business on the open market for cash, and the sale prices do not reflect brokerage commissions paid.

In addition, during the Reporting Period, the Fund sold the standard American-style, exchange-traded call options described in Item 6, which is incorporated by reference into this Item 5(c).

5. Item 6 of the Schedule 13D shall hereby be amended and restated in full as follows:

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

The table below lists the standard American-style, exchange-traded call options (“Call Options”) sold by the Fund during the Reporting Period, all of which are outstanding as of November 25, 2024. Each of the below listed transactions was conducted in the ordinary course of business on the open market for cash, and the sale prices do not reflect brokerage commissions paid.

CUSIP No. 63886Q109				Page 7 of 8 Pages

 

Date of Sale		Value per Underlying Share at which Call Options were Sold ($)				Shares Underlying Call Options (100s)				Call Options’ Strike Price per Share ($)				Call Options’ Expiration Date
11/18/2024		$	0.8530				150			$	27.50				01/17/2025
11/19/2024		$	0.9667				150			$	27.50				01/17/2025
11/20/2024		$	1.0500				200			$	27.50				01/17/2025
11/21/2024		$	0.8500				250			$	27.50				12/20/2024
11/22/2024		$	1.0500				200			$	30.00				01/17/2025
11/25/2024		$	1.1273				33			$	27.50				12/20/2024
11/25/2024		$	0.9158				653			$	30.00				01/17/2025

Each of these Call Options gives the option’s counterparty the right (but not the obligation) to purchase from the Fund, on or before the option’s expiration date, the number of shares of Common Stock underlying the option, at a purchase price per share equal to the option’s strike price per share. If a Call Option is exercised on or before its expiration date, the Fund must deliver the shares of Common Stock underlying the option in exchange for the option’s aggregate exercise price.

Except as otherwise described in this Schedule 13D, including the Exhibits attached hereto, there are no contracts, arrangements, understandings, or relationships (legal or otherwise) among the Reporting Persons, or between any Reporting Person(s) and any third party, with respect to any securities of the Issuer, including, but not limited to, those involving the transfer or voting of any of the securities, finder’s fees, joint ventures, loan or option arrangements, put or calls, guarantees of profits, division of profits or losses, or the giving or withholding of proxies.

6. Except as expressly modified hereby, all provisions of the Schedule 13D shall continue in full force and effect.
