How were the 40 new NGS shares acquired by the director?

Following the dividend reinvestment, indirect holdings total 13,704 NATURAL GAS SERVICES common shares. These shares are held in a Rabbi Trust tied to the company’s deferred compensation plan, reflecting equity accumulated on the director’s behalf rather than shares bought directly on the open market.

How many NGS Restricted Stock Units does the director hold after this filing?

After the reported transactions, the director holds 4,456 Restricted Stock Units in NATURAL GAS SERVICES. Each unit represents the right to receive one share of common stock upon vesting, providing future potential equity, separate from his directly and indirectly held common stock positions.

What are the director’s direct NGS common stock holdings after the Form 4?

Direct holdings total 1,509 NATURAL GAS SERVICES common shares after the Form 4. These directly held shares are separate from the 13,704 shares held indirectly through the Rabbi Trust and from the 4,456 Restricted Stock Units that may convert into common stock upon vesting.
