Insights

Pre-planned insider share sales represent a modest, routine disposition.

Kristopher Hanson, General Counsel of MapLight Therapeutics, sold 13,917 shares of Voting Common Stock in four open-market transactions. All trades occurred on May 11, 2026 pursuant to a pre-arranged Rule 10b5-1 trading plan, indicating the timing was scheduled in advance.

The reported sale prices are weighted averages, with underlying trades executed in ranges from $27.26 to $30.90 per share. Following the sales, Hanson continues to hold 175,964 shares directly, and the filing shows no remaining derivative positions such as options or warrants.

4 terms

Rule 10b5-1 trading plan regulatory

"This transaction was made pursuant to a Rule 10b5-1 trading plan adopted by the Reporting Person on December 29, 2025."

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.

Voting Common Stock financial

"security_title: "Voting Common Stock""

open-market sale financial

"transaction_action: "open-market sale""

An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.
