Why did Michael Lonon receive only 0.9556 WESCO share equivalents in this award?

The 0.9556 share equivalents reflect the calculated dividend equivalent rights on his outstanding restricted stock units. The figure is fractional because it is based on the dividend rate and RSU balance, producing a precise economic equivalent rather than a rounded whole-share grant.

4 terms

dividend equivalent rights financial

"Represents dividend equivalent rights ("DERs") in connection with the Issuer's quarterly dividend"

Dividend equivalent rights are promises that mirror the cash payments shareholders get from a company’s profits, but they are paid to holders of certain awards (like stock options or restricted stock units) rather than to actual shares. Think of them as a paycheck top‑up that matches dividends while the award is not yet a real stock, and they matter to investors because they add to employee compensation costs and potential share dilution, affecting company profitability and per‑share value.

DERs financial

"Each DER is the economic equivalent of one share of Issuer's common stock"

restricted stock units financial

"accrued to the Reporting Person on restricted stock units ("RSUs") held by the Reporting Person"

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.

Form 4 regulatory

"INSIDER FILING DATA (Form 4):"

Form 4 is a official document that company insiders, such as executives or major shareholders, file with regulators whenever they buy or sell company shares. It provides transparency about how those with inside knowledge are trading, helping investors see if insiders are confident in the company's prospects or may be selling for personal reasons. This information can influence investor decisions by revealing insiders' perspectives on the company's value.
