Employee Stock Purchase Plan financial

"acquisition of shares of the Issuer's Class A Common Stock pursuant to the Rivian Automotive, Inc. 2021 Employee Stock Purchase Plan"

An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.

Rule 16b-3(c) regulatory

"The acquisition of those 2,756 shares of Class A Common Stock was also exempt pursuant to Rule 16b-3(c)."

An SEC rule that lets corporate insiders avoid automatic "short‑swing" profit recovery when they buy or sell their company’s stock under a pre‑approved, written plan that meets specific conditions. For investors, it matters because it clarifies when insider trades are treated as routine, reducing legal uncertainty and helping distinguish trades made for ordinary compensation or pre‑planned reasons from those that might signal opportunistic or timely insider advantage.

Offering Period financial

"for the purchase period of November 21, 2025 through May 20, 2026 (the "Offering Period")."

Class A Common Stock financial

"The acquisition of those 2,756 shares of Class A Common Stock was also exempt"

Class A common stock is a category of a company’s shares that carries a specific set of ownership rights—most commonly defined voting power and claims on dividends—set out in the company’s charter. For investors it matters because the class determines how much influence you have over corporate decisions, the share’s likely dividend and trading behavior, and how it compares in value to other share classes, like choosing a particular seat with different privileges at the company’s decision-making table.
