3 terms

10b5-1 plan regulatory

"Shares sold pursuant to a 10b5-1 plan dated June 15, 2026."

A 10b5-1 plan is a pre-arranged strategy that allows company insiders to buy or sell their shares at predetermined times and prices, even while they are aware of confidential information. It acts like a scheduled appointment for trading, helping ensure transactions happen transparently and legally, which can reassure investors that trades are not based on insider knowledge.

weighted-average sales price financial

"Price reported is a weighted-average sales price."

Revocable Trust financial

"Shares are held by the Alexis Le-Quoc Revocable Trust."

A revocable trust is a legal arrangement where the person who creates it keeps control and can change or cancel the trust at any time, while naming who will manage and receive the assets later. Think of it like a flexible folder for your investments and property that can be relabeled or reworked as circumstances change; it matters to investors because it determines how ownership is recorded, how easily assets transfer on incapacity or death, and whether holdings bypass public probate proceedings.
