Martinez Magdalena 4/A

What Happened

• Magdalena Martinez, Chief Operating Officer of Sensus Healthcare (SRTS), had 741 shares withheld on December 19, 2023 to cover her tax withholding obligation arising from the vesting of restricted stock. The shares were withheld at an effective price of $2.66 per share for a total value of about $1,971. This was a tax-withholding event (routine) rather than an open-market sale or purchase.

Key Details

• Transaction date and price: December 19, 2023 — 741 shares withheld at $2.66/share (total ~ $1,971).
• Shares owned after transaction: The filing corrects prior reporting — Martinez held 12,013 shares as of December 19, 2023 (including 7,500 restricted shares). A prior Form 4 had incorrectly reported 9,759 shares.
• Footnotes: F1 indicates shares were withheld solely to pay withholding tax on vested restricted stock. F2 is the correction to previously misstated ownership.
• Filing status/timeliness: This is an amended Form 4 filed April 22, 2026 that corrects the earlier ownership figure; the amendment indicates the original report contained an ownership error.

Context

• Tax-withholding (code F) is a routine administrative action when restricted stock vests and generally does not indicate a change in insider sentiment about the company. No open-market sale or purchase occurred in this transaction.
