Insights

Equity capital markets analyst

Form 144 discloses a planned 10,000‑share insider sale for NGS, alongside recent prior sales, and appears modest versus shares outstanding.

The filing shows Stephen Taylor intends to sell 10,000 shares of Natural Gas Services Group common stock through RBC Capital Markets LLC, with an indicated $310,069.00 aggregate market value on the NYSE. The class has 12,542,314 shares outstanding, suggesting this planned transaction is small relative to the total equity base. The shares to be sold were acquired via an RSU vest from the issuer on 02/21/2018, which is a typical executive compensation mechanism.

The disclosure of prior sales in the last three months indicates ongoing liquidity events rather than a single, large disposition. Examples include 20,000 shares sold on 08/22/2025 for $525,060.00 and 18,748 shares sold on 11/10/2025 for $558,095.00. Form 144 is a notice, not an execution report, so actual sales can differ from the proposed amount. The representation that the seller is not aware of undisclosed material adverse information aligns with regulatory expectations for insider trading safeguards.
