Northfield Bancorp EVP Robin Lefkowitz Surrenders Shares in Merger

What Happened
Robin Lefkowitz, Executive Vice President of Northfield Bancorp, reported multiple dispositions to the issuer on July 20, 2026 totaling 141,937.26 shares/derivative units. The filing lists five dispositions: 23,534; 26,135.8; 38,388.46 (common shares) and 13,879; 40,000 (derivative items). No per-share sale price is reported (listed as N/A) because these were conversions/dispositions under the merger rather than open-market trades. Under the merger agreement, each Northfield common share was converted into the right to receive either 1.425 shares of Newco common stock or $14.25 in cash; if the cash election applied to the 88,058.26 common-share portion, that would imply roughly $1.255M in cash (actual consideration depends on holder elections and treatment of derivative awards).

Key Details

  • Transaction date: 2026-07-20 (report period 2026-07-20).
  • Shares/units disposed: total 141,937.26 — common shares: 88,058.26 (23,534; 26,135.8; 38,388.46); derivatives: 53,879 (13,879; 40,000).
  • Price: N/A in filing (dispositions were conversion/settlements under the merger).

    • F1: Each outstanding Northfield common share converted to the right to elect either 1.425 Newco shares or $14.25 cash at merger close.
    • F2: Restricted stock units were converted into 1.425 units to be settled in cash based on Newco’s closing price on vesting.

  • Filing timeliness: reported with period date 2026-07-20 (no late filing flag shown).

Context
These were issuer dispositions tied to the Columbia/Newco merger—not open-market sales—so they reflect conversion/settlement mechanics (stock-for-stock or cash election) rather than a discretionary sell decision. Derivative items (RSUs/options) are treated differently: RSUs were converted into cash-settled units per the agreement, and options were converted into Newco options rather than immediately cashed out. For retail investors, merger-driven conversions are routine corporate actions and do not necessarily signal insider sentiment about future company performance.
