TRINGALI DONALD J 4

What Happened

• Donald J. Tringali, a director of Natural Gas Services Group, had restricted stock units (RSUs) vest on June 5, 2026, resulting in the acquisition of 4,456 shares (446 + 4,010). The filing shows a conversion/exercise of a derivative instrument for 4,456 shares at a $0.00 exercise price (i.e., the RSUs converted into common shares rather than a market purchase or sale).

Key Details

• Transaction date: June 5, 2026; Form 4 filed June 8, 2026 (appears timely).
• Shares acquired via RSU vesting: 4,456 total (446 and 4,010 reported in two award lines).
• Exercise/conversion: 4,456 shares at $0.00 (derivative converted to common stock).
• Shares owned after transaction: not specified in the supplied data.
• Footnotes: F1 notes the shares were acquired upon RSU vesting; F2 clarifies each RSU equals one share at vesting, with an election allowance of up to 50% in cash.

Context

• This was an award/vesting event, not an open-market purchase or sale. The $0.00 exercise price reflects conversion of RSUs into shares rather than a cash exercise. The filing does not indicate any immediate sale of the shares; RSU vesting and conversions are typically routine compensation events rather than direct signals of insider buying or selling.
