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.
