FAQ

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

What insider transaction did WESCO (WCC) director Michael Lonon report?

Michael Lonon reported receiving a grant of 659 restricted stock units in WESCO common stock. These RSUs are a form of equity compensation and do not involve a cash purchase, aligning the director’s interests with long-term company performance through future share delivery.

How many WESCO (WCC) shares are covered by Michael Lonon’s new RSU grant?

The grant covers 659 restricted stock units, each representing a contingent right to one share of WESCO common stock. If all units vest and settle in shares, the award would result in 659 additional shares being delivered to the director, subject to vesting conditions.

When do Michael Lonon’s WESCO (WCC) RSUs vest?

The restricted stock units vest in full on the first anniversary of the grant date. Vesting means the director earns the right to receive the underlying WESCO common shares, assuming any service or other conditions tied to the RSUs are satisfied at that time.

Did Michael Lonon pay cash for the 659 WESCO (WCC) RSUs?

No cash was paid for the 659 RSUs, which were granted at a price of $0.00 per unit. This indicates they were awarded as part of an equity compensation arrangement rather than purchased in an open-market or privately negotiated transaction for cash consideration.

What does each WESCO (WCC) RSU granted to Michael Lonon represent?

Each RSU represents a contingent right to acquire one share of WESCO common stock after vesting. Contingent rights mean the director only receives actual shares once specific vesting conditions, such as continued service through the first anniversary of the grant, are fully met.
