4 terms

Restricted Units financial

"elected to receive a grant of Series 2026I restricted limited partnership interests ("RUs")"

OP Units financial

"automatically convert into an equal number of limited partnership interests of the OP ("OP Units")"

OP units are ownership stakes in an operating partnership that sits beneath a public parent company, commonly used by real estate and energy firms to hold assets and distributions. Think of them like special shares in a subsidiary: they give economic rights to profits and cash payouts but are structured differently from the parent’s common stock, so investors watch OP unit issuance because it can change the effective ownership, future distributions, and potential dilution of the parent company’s equity.

holding restriction financial

"RUs (including any OP Units into which they may automatically convert) are subject to a holding restriction"

weighted average price financial

"The price represents the weighted average price of the shares sold."

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.
