Class A market

"Class A | Fidelity Brokerage Services LLC 900 Salem Street"

Class A denotes a specific group of a company’s shares that carry a particular set of rights—most commonly different voting power or dividend priority compared with other share classes. Think of it like different seats on a bus where some seats let you steer and others only ride: knowing whether a share is Class A tells investors how much influence they have over company decisions and how returns might be distributed, which affects control and value.

Gross proceeds financial

"16257 | 975420.00"

The total amount of cash a company receives from a financing event or sale before any fees, expenses, taxes or deductions are taken out. Investors watch gross proceeds because it shows the raw scale of new capital being raised—think of it as the paycheck amount before withholdings—which helps assess how much funding is available for operations, growth, debt payoff or how much shareholder dilution might occur once costs are removed.

What does OKLO's Form 144 disclosure mean?

It notifies the SEC of proposed sales of restricted or affiliate Class A shares. The filing lists specific sale dates, share counts, and gross proceeds so brokers and the market can note planned dispositions.

The filing lists 72,090 shares sold on 03/13/2026 for $4,325,320.70. This line shows the transaction date, share count, and reported gross proceeds for that disposition.

Who is the broker handling the reported OKLO sales?

The filing names Fidelity Brokerage Services LLC at 900 Salem Street, Smithfield, RI, as the broker. The broker is recorded alongside the Class A securities and sale notifications.

Does the Form 144 show how the shares were acquired?

Yes; the notice references Options Granted 12/23/2023 as the acquisition source for the Class A shares. That indicates the shares arise from option exercises tied to that grant date.
