Smart Money Convergence

OIS does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.

13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

Oil States International amended its CEO Lloyd Hajdik's executive agreement to change how severance is calculated. Under the new terms, if he is let go without cause or resigns for good reason within 24 months after a change in control, he gets a lump sum equal to 3 times his base salary and target bonus. If the termination happens outside that window, he gets 1.5 times. The rest of the agreement stays the same.
