"restricted stock units became fully vested on 5/19/2026, of which 1,961 shares were traded"
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

How many CMCO shares does the CFO hold after these transactions?

Following the tax-withholding dispositions, Gregory Rustowicz directly holds 93,063.71 shares of Columbus McKinnon common stock. This figure reflects his remaining direct ownership after 2,694 shares were used to cover tax liabilities on vested restricted stock units.

What CMCO equity awards vested for the CFO in May 2026?

Restricted stock units vested for the CFO on May 19 and May 20, 2026. One tranche of 4,521.063 units and another of 1,685.826 units became fully vested, triggering associated tax obligations settled with a portion of the resulting shares.

Does the CMCO CFO still have unvested restricted stock?

Yes. After these transactions, 13,461.821 shares of restricted stock remain subject to forfeiture for the CFO. These shares vest over time through May 2027 and May 2028, provided he continues as an employee of Columbus McKinnon.

What do the F-coded transactions mean in the CMCO Form 4?

The F-coded transactions indicate payment of tax liability by delivering securities. In this case, the CFO used shares of Columbus McKinnon common stock received from vesting restricted stock units to cover withholding taxes instead of making a separate cash payment.
