Le Slip Français plans Bastille Day listing on Euronext Growth Paris

Le Slip Français will debut on Euronext Growth Paris on Bastille Day, July 14, at €14.80 a share, with Euronext’s IPO showcase listing the ticker as ALLSF, the ISIN as FR0014018Y10 and Euroland Corporate as sponsor and agent. The underwear maker is aiming to raise €5 million through a mix of new shares and secondary sales.

Founded in 2011, the company responded to pressure on French textile makers from Inditex, H&M and, later, Shein. Its first products were men’s underwear in the colors of the French flag, a deliberate national badge that later expanded into women’s wear, pajamas and other clothing. Guillaume Gibault, the chief executive, said the business was an attempt to change the world by changing underwear.

Le Slip Français is an “entreprise à mission” under France’s 2019 Pacte law and is B Corp certified. Annual clothing sales are about €21.1 million, and net profit was €700,000 last year. Recent figures put 2025 revenue at about €21 million, with an EBITDA margin of 10%, or roughly €2.1 million.

Le Slip Français closed 17 of its 20 stores and now generates about 70% of revenue online, after once reaching 22 stores and 120 employees. The company was under financial strain in 2023, but returned to profitability in 2025 after closing stores and shifting away from physical retail. The offering would give public investors about 27% of the capital, existing shareholders can also sell stock, and the deal could expand to as much as €15.8 million if the overallotment option is fully exercised. Institutional investors had already committed €6.85 million before the listing.
