FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What did RGR Treasurer and CFO Thomas Dineen report on this Form 4?

He reported the vesting of 8,485 cash-settled restricted stock units. The vesting is shown as both a deemed acquisition and disposition of common shares, reflecting how the cash-settled RSUs are accounted for when they convert based on the share price at vesting.

How many restricted stock units vested for the RGR CFO and when?

A total of 8,485 cash-settled restricted stock units vested for the CFO on March 1, 2026. These units were originally granted on June 8, 2023 and each unit represents the fair market value of one share of Sturm Ruger common stock at the vesting date.

Are the vested RSUs in RGR stock or cash-settled for the CFO?

The RSUs are cash-settled and not traditional stock awards. Each unit represents the contingent right to receive the fair market value of one Sturm Ruger common share on the vesting date, and the Form 4 reflects this as deemed share acquisitions and dispositions.

Why does the RGR Form 4 show both acquisition and disposition of the same 8,485 shares?

The filing explains that vesting of cash-settled RSUs is reported as a deemed acquisition and disposition of the underlying shares. This accounting treatment records the RSU vesting economically as if shares were acquired and then disposed of, rather than an open-market stock trade.

How are indirect holdings with the spouse reported in this RGR Form 4?

Some common stock positions are reported as indirectly owned "with spouse." The Form 4 shows both an issuer disposition and a corresponding acquisition in these indirect holdings, consistent with how the vested cash-settled RSUs are treated for reporting the CFO’s beneficial ownership changes.
