"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.

Rule 144 notice regulatory

"Form type indicated as 144 and securities sold during the past 3 months"

A Rule 144 notice is a public filing that an insider or holder of restricted stock submits when they plan to sell shares that aren’t freely tradable yet; it lists how many shares they intend to sell and under what conditions. For investors, it matters because it signals potential insider selling and an upcoming increase in shares available to the market—similar to someone announcing a big garage sale, which can affect supply and price expectations.

FAQ

What Class A sales did Nancy J. Johnson report for BLLN?

Nancy J. Johnson reported two sales: 3,418 shares on 06/08/2026 for $339,347.28 and 10,582 shares on 06/09/2026 for $1,063,192.55. The filing lists dates, share counts, and gross proceeds for each transaction.

Does the filing show whether proceeds went to the issuer or selling holder (BLLN)?

The excerpt attributes the transactions to the selling holder, showing gross proceeds for each sale. It does not state that proceeds were received by the issuer; the entries list the selling holder and cash amounts associated with each disposition.

What is the meaning of the "Pre-IPO Shares" line in this filing?

The excerpt includes a line labeled Pre-IPO Shares dated 07/03/2020 showing 801 Class A shares. This line appears as a security description in the filing; the excerpt does not explain any transfer or registration beyond that label.

Was a broker or clearing agent listed for these transactions in the filing?

The excerpt names Fidelity Brokerage Services LLC with an address and lists Class A alongside numeric fields. That entry appears on the filing page, but the excerpt does not explicitly map the broker role to each sale beyond the name and address shown.
