3 terms

weighted average price financial

"The price reported in Column 4 is a weighted average price."

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

tax withholding obligations financial

"shares ... sold to satisfy tax withholding obligations relating to the acquisition"

restricted stock unit agreement financial

"pursuant to provisions of a restricted stock unit agreement by and between the Issuer"

A restricted stock unit agreement is a written contract between a company and an individual that describes a promise to deliver company shares or cash later, subject to conditions such as time-based vesting or performance targets. Think of it like a timed gift: the recipient only receives the shares if they meet the agreed conditions. Investors care because these agreements create future share issuance, affect potential dilution, corporate expenses and incentives for insiders, and influence when insiders may sell shares.
