Rule 10b5-1 trading plan regulatory

"These sales were effected by the Reporting Person pursuant to a Rule 10b5-1 trading plan adopted on June 11, 2026."

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.

weighted average price financial

"The price reported in Column 4 is a weighted average price."

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

multiple transactions financial

"These shares were sold in multiple transactions at prices ranging from $2.135 to $2.148, inclusive."
