SCHEDULE 13D/A

Rhea-AI Filing Summary

Sofinnova Crossover I SLP and related parties filed Amendment No. 6 to their Schedule 13D on Abivax S.A. after a series of open‑market sales of American depositary shares (ADSs) and ordinary shares on NASDAQ and Euronext.

Between June 30 and July 6, 2026, Sofinnova sold blocks of ADSs and ordinary shares at weighted average prices mostly above $130 per share. Following these transactions, Sofinnova held 2,474,299 ordinary shares, representing about 3.1% of Abivax’s outstanding ordinary shares, and 3,535,843 voting rights, or about 4.3% of outstanding voting rights as of May 31, 2026.

The filing emphasizes that Sofinnova acquired its position for investment purposes but may buy or sell additional Abivax securities over time, and that individual investment committee members disclaim beneficial ownership beyond their economic interest.

Schedule 13D regulatory
"This Amendment No. 6 … amends and supplements the filed with the Securities and Exchange Commission…"
A Schedule 13D is a legal document that investors file with regulators when they buy a large enough stake in a company to potentially influence its management or decisions. It provides details about the investor’s intention, ownership stake, and plans, helping other investors understand who is gaining control and what their motives might be.
beneficially owns financial
"The Reporting Person beneficially owns 2,474,299 Ordinary Shares…"
Beneficially owns means a person or entity enjoys the economic benefits and control of a security even if the legal title or registration is held in another name. Think of it like having the keys and profits from a car that is registered to a friend: you use it, benefit from it, and make decisions about it even though the official paperwork lists someone else. For investors, this matters because it reveals who truly controls shares, affects voting power, potential conflicts of interest, and regulatory disclosure obligations.
voting rights financial
"…and has 3,535,843 voting rights related to such shares."
Voting rights are the ability of shareholders to have a say in important company decisions, like choosing leaders or approving big changes. They matter because they give owners a voice in how the company is run, similar to how voters influence elections, ensuring the company acts in shareholders’ interests.
American depositary shares financial
"…including ordinary shares represented by American depositary shares…"
American depositary shares (ADSs) are a way for investors in the United States to buy shares of foreign companies without dealing with international markets directly. They represent ownership in a foreign company's stock and are traded on U.S. stock exchanges, making it easier for American investors to buy, sell, and own parts of companies from around the world.
weighted average price financial
"…at a weighted average price of $132.7347 per share."
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.
investment committee financial
"…the members of the investment committee of SC…"
An investment committee is a small group of experienced people who set the rules and make the key decisions about what investments to buy, hold, or sell for a fund, pension, or portfolio. Think of them as the steering team that balances goals, potential returns and risk—their choices shape how much money investors are likely to gain or lose and provide consistent oversight so decisions aren’t made impulsively.
