LeonaBio, Inc.: what insiders have been doing
LeonaBio, Inc. is a listed company. Its insiders report their share dealings to SEC (Form 4). In the past year (18 October 2025 to 18 October 2026), 12 filings came from 6 insiders.
The filings describe grants, exercises and other transfers rather than trades on the open market. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.
Across the 5,458 companies tracked on its exchange, the median is 22 filings; at 12 filings, this issuer sits below that mark. Since 2021, the database holds 18 purchases and no sales by insiders of the company. The 10-K for the year ended 31 December 2025 shows -105.6 m USD of net income.
There has been no open-market purchase by an insider of LeonaBio, Inc. for at least a year. The median gap between a trade and its publication by SEC (Form 4) is 4 days. Section 16 rules allow two business days to file each Form 4.
In the same market, recent insider purchases at GameStop Corp. and Heico Corp also feature in our signals. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
