Insights

Insider trading and governance analyst

CFO’s pre-planned sale is modest relative to remaining holdings.

Liberty Energy’s CFO, Michael Stock, sold 19,998 shares of Class A common stock in an open-market transaction at a weighted average price of $33.48 per share. This is reported as a straightforward sale of non-derivative shares.

The sale was executed under a Rule 10b5-1 trading plan adopted on February 17, 2026 for transactions beginning in May 2026, indicating it was pre-scheduled rather than opportunistic. Such plans are commonly used to systematize insider sales and reduce concerns about trade timing.

After this transaction, Stock directly holds 800,375 shares, suggesting he maintains substantial exposure to Liberty Energy Inc. The filing notes a price range of $33.37 to $34.00 for the individual trades within the reported average. Future filings will show whether additional scheduled sales occur under the same plan.

4 terms

Rule 10b5-1 trading plan regulatory

"The sales were effected pursuant to a Rule 10b5-1 trading plan adopted by the Reporting Person"

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.

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.

Class A Common Stock financial

"security_title: "Class A Common Stock""

Class A common stock is a category of a company’s shares that carries a specific set of ownership rights—most commonly defined voting power and claims on dividends—set out in the company’s charter. For investors it matters because the class determines how much influence you have over corporate decisions, the share’s likely dividend and trading behavior, and how it compares in value to other share classes, like choosing a particular seat with different privileges at the company’s decision-making table.
