Rule 10b5-1 trading plan regulatory

"The filer indicated the trade was made under a Rule 10b5-1 trading plan."

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

beneficially owned financial

"Reflects 2,857,490 shares of Common Stock beneficially owned by the Reporting Person immediately prior"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

ten percent owner regulatory

"The reporting person is identified as a ten percent owner of Lyell Immunopharma, Inc."
