Delcath (DCTH) COO Martha Rook Receives Equity Awards

What Happened
Martha S. Rook, Chief Operating Officer of Delcath Systems, Inc. (DCTH), was granted two equity awards on February 17, 2026: 56,500 derivative option units and 28,250 restricted stock units (RSUs), for a combined 84,750 award units. Both awards are reported with an acquisition price of $0 because they are compensation grants (transaction code A), not open-market purchases. No sale or exercise of shares was reported.

Key Details

  • Transaction date: February 17, 2026; Form 4 filed February 18, 2026 (timely).
  • Reported amounts: 56,500 derivative option units @ $0.00; 28,250 RSUs @ $0.00 (total 84,750 units).
  • Shares owned after transaction: not specified in this filing.
  • Footnotes:
    • F1 (options): Vest and become exercisable at 1/36th per month beginning Feb 17, 2026, subject to continued employment and plan terms.
    • F2 (RSU definition): Each RSU represents a contingent right to receive one share of common stock.
    • F3 (RSU vesting): One-third of the RSUs vest on Feb 17, 2027; the remaining two-thirds vest in equal annual installments over the following two years, subject to continuous service.
  • Transaction code: A = Award/Grant (derivative equity compensation).

Context
These grants are compensation awards (options + RSUs) with multi-year vesting schedules and do not involve an immediate cash purchase or sale. That means they reflect company compensation policy rather than an open-market trade; they should be viewed as long-term retention/compensation instruments rather than an immediate bullish or bearish trading signal.
