Insights

CEO’s entity sells 75,000 shares under a pre-set 10b5-1 plan while retaining a large overall stake.

Liquidia’s CEO, Roger Jeffs, reported three indirect open-market sales totaling 75,000 shares of common stock at volume-weighted average prices between $40.10 and $42.09. The shares were sold by Serendipity BioPharma LLC, where Jeffs has sole voting and dispositive power.

A footnote states the transactions were executed pursuant to a Rule 10b5-1 plan adopted on November 5, 2025, indicating the sales were pre-arranged rather than timed opportunistically. The filing also corrects a prior administrative error that had miscounted 91 shares in an earlier Form 4.

Following these sales, Serendipity reports holding 1,348,095 shares indirectly, a living trust holds 46,595 shares indirectly, and Jeffs directly owns 1,137,508 shares, alongside substantial unvested RSU awards. This context suggests the sales represent a minority portion of his total reported economic exposure.

Rule 10b5-1 plan financial
"Transaction effected pursuant to a Rule 10b5-1 plan adopted by the Reporting Person"
A Rule 10b5-1 plan is a prearranged, written schedule that lets corporate insiders buy or sell company stock at set times or amounts, even if they later learn material nonpublic information. Think of it like setting an automatic thermostat for trades: it creates a clear record that trades were planned in advance, reducing the risk of insider-trading accusations and helping investors trust that insider transactions are routine rather than based on secret information.
restricted stock units ("RSUs") financial
"Includes (i) 54,281 unvested restricted stock units ("RSUs") of the 289,500 RSUs granted"
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.
volume weighted average price financial
"Price is the volume weighted average price of all transactions made by the Reporting Person"
The volume weighted average price (VWAP) is a way to measure the average price of a security, such as a stock, over a specific period, taking into account how many units were traded at each price. It’s similar to calculating the average cost of items bought when some are more frequently purchased than others. Investors use VWAP to assess whether a security is being bought or sold at a fair price during trading.
beneficially owned financial
"The amount of securities beneficially owned by the Reporting Person following the transactions reported herein has been corrected"
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.
dispositive power financial
"The Reporting Person is a manager of Serendipity and has sole voting and dispositive power"
Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.

FAQ

What insider transaction did Liquidia (LQDA) CEO Roger Jeffs report in this Form 4?

Roger Jeffs reported indirect open-market sales of 75,000 Liquidia common shares over three days. The shares were sold by Serendipity BioPharma LLC, an entity he manages, at volume-weighted average prices around the low-$40 range as disclosed in the filing’s transaction details.

How many Liquidia (LQDA) shares did Serendipity BioPharma LLC sell and at what prices?

Serendipity BioPharma LLC sold 75,000 Liquidia shares in three blocks of 25,000. The reported volume-weighted average prices were $40.1037, $40.7829, and $42.0854, each representing aggregated trades within stated intraday price ranges outlined in the footnotes.

Were Roger Jeffs’ Liquidia (LQDA) share sales made under a Rule 10b5-1 plan?

Yes. A footnote explains the transactions were effected pursuant to a Rule 10b5-1 plan adopted on November 5, 2025. Such plans pre-schedule trades, indicating these sales followed a predetermined arrangement rather than being initiated at Jeffs’ discretion on the trade dates.

How many Liquidia (LQDA) shares does Roger Jeffs report owning after these transactions?

After the reported sales, Serendipity BioPharma LLC holds 1,348,095 Liquidia shares indirectly, a living trust holds 46,595 shares indirectly, and Jeffs directly owns 1,137,508 shares. The filing also lists multiple grants of unvested restricted stock units that add to his overall equity exposure.

What restricted stock unit (RSU) awards for Liquidia (LQDA) does Roger Jeffs disclose?

The filing notes unvested RSUs from several grants: 54,281 from a 2023 grant, 96,835 from a 2024 grant, 157,662 from a 2025 grant, and 115,344 from a 2026 grant. None of these RSUs had vested as of the Form 4’s reporting date, enhancing Jeffs’ future equity alignment.

Did this Liquidia (LQDA) Form 4 correct any prior reporting errors for Roger Jeffs?

Yes. A footnote states the beneficially owned amount was corrected because a previous Form 4 filed January 14, 2025 inadvertently excluded 91 common shares from a reported sale. This filing updates the total to reflect that earlier administrative error and clarifies current holdings.
