BOIRON
This page covers one establishment of BOIRON. It is not a separate company. The SIRET number 967 504 697 00673 identifies BOIRON’s site at 18 rue de l’Innovation, 42000 Saint-Étienne, France. In the INSEE Sirene register this establishment was created on 27 August 2001. It replaced an earlier Saint-Étienne establishment at 24 rue de la Télématique, which operated from 1988 to 2001. The site is recorded as closed (fermé) since 7 February 2020. It was not the registered office.
The legal entity is BOIRON, a French société anonyme à conseil d’administration (an SA with a board of directors). Its SIREN is 967 504 697 and it is registered with the RCS Lyon. Sirene gives the legal unit a creation date of 1 January 1967, and GLEIF records the same date (LEI 9695000UMPNY21KKDO98). The laboratories themselves were founded in 1932 by the pharmacists Jean and Henri Boiron. The legal unit is active. Its registered office is at 2 avenue de l’Ouest Lyonnais, 69510 Messimy, and its main activity code is NAF 21.20Z (manufacture of pharmaceutical preparations). On 22 October 2026 Sirene listed 98 establishments for the SIREN, 14 of them open. So the closed status on this page describes the Saint-Étienne site, not the company.
BOIRON develops, manufactures and distributes homeopathic medicines. These include common-name products sold as granules and globules, branded homeopathic specialities for self-medication, and other health products such as medical devices, food supplements, herbal products and cosmetics. According to its 2025 annual financial report, BOIRON supplies about 20,000 French pharmacies through eleven distribution establishments, operates in about fifty countries, and made 59% of its 2025 sales outside France. Its shares trade on Euronext Paris under the ticker BOI (ISIN FR0000061129).
Consolidated BOIRON group revenue for 2025 was €501.1 million, up 2.8%, and group-share net profit was €32.6 million. At the level of the legal entity alone, BOIRON SA reported 2025 revenue of €335.2 million and a net loss of €0.33 million, with an average of 1,685 full-time-equivalent employees. The group as a whole had 2,634 employees at the end of 2025, 1,725 of them in France. In the first half of 2026, group-share net profit was €4.9 million and revenue was 0.3% lower at constant exchange rates.
Recent changes to the French network: a reorganisation presented on 21 November 2024 led to the closure of four establishments and seven preparation units in the second half of 2025, and the Antibes (Sophia Antipolis) site was sold in the first half of 2026. The closure of the Saint-Étienne site in February 2020 came before the restructuring plan announced in March 2020. None of the filings reviewed gives a reason for it.

Registration details
Officers
Directors and officers of BOIRON
French registers record officers against the legal entity, BOIRON SA (SIREN 967 504 697). They do not record officers for an establishment such as the closed Saint-Étienne site (SIRET 96750469700673). This block therefore describes the management of the company.
BOIRON is a société anonyme with a board of directors, and the roles of chairman and chief executive are held by different people. The board has had thirteen members since the general meeting of 23 May 2024. They include one director representing employee shareholders and two directors representing employees. According to the BODACC notices, the current officers are:
- Anabelle Flory-Boiron, Chairman of the Board (Président du conseil d’administration). The BODACC notice recording this was published on 20 October 2024.
- Pascal Houdayer, Chief Executive (Directeur général) from 1 January 2025. He has also been a director since 2025.
- Frédéric Riou, Deputy Chief Executive (Directeur général délégué) and Pharmacien responsable (responsible pharmacist) from 1 June 2025.
Three companies sit on the board as corporate directors. Each acts through a permanent representative, as listed in the 2025 report:
- BOIRON DÉVELOPPEMENT (SIREN 953 894 037), represented by Laurence Boiron.
- DOMINO FUND 3 HOLDCO GP LLC, a company incorporated outside France, represented by Evis Hursever.
- FIDENTIS, represented by Philippe Brun. FIDENTIS is classed as independent.
The statutory auditors are FORVIS MAZARS and GRANT THORNTON. Grant Thornton replaced Deloitte & Associés, as published in BODACC on 19 October 2023. The registers do not record nationality for these officers, so it is not disclosed here.
Recent officer changes
- 31 December 2025: Thierry Boiron left his role as Deputy Chief Executive. He remains a director of BOIRON (BODACC notice published 16 January 2026; 2025 annual financial report).
- 1 June 2025: Frédéric Riou became Deputy Chief Executive and responsible pharmacist, replacing Jean-Christophe Bayssat, who retired (BODACC notice published 15 June 2025).
- 1 January 2025: Pascal Houdayer became Chief Executive, replacing Thierry Boiron. The board had appointed him on 11 December 2024 (BODACC notices published 9 and 14 February 2025).
Data availability
Availability is full for the legal entity: BODACC publishes a dated notice each time the administration changes, and the annual report lists every board seat. The consolidated list in the RNE / recherche-entreprises service is out of date. On 22 October 2026 it still named Jean-Christophe Bayssat as Deputy Chief Executive, although he left on 31 May 2025, so the dated BODACC notices were used instead. Nationality is not published in these sources.

Group Structure
Group structure of BOIRON
The Saint-Étienne site (SIRET 96750469700673) was a branch-type establishment of BOIRON SA (SIREN 967 504 697), not a subsidiary. It was part of the same legal person and has been closed since 7 February 2020. BOIRON SA is the parent of the BOIRON group.

It held 78.98% of BOIRON’s capital at 31 December 2025. The 2025 annual financial report describes it as the group’s lead holding company (“holding animatrice”) and says it consolidates BOIRON in its own accounts. The report places control of BOIRON DÉVELOPPEMENT with a family-led concert, which includes the family holding companies SODEVA and SHB. Ownership percentages above BOIRON DÉVELOPPEMENT are not published.
BOIRON SA fully consolidates 25 subsidiaries. They are in Belgium, Italy, the United States, Spain, Canada, the French overseas departments (Martinique and La Réunion), the Czech Republic, Slovakia, Poland, Romania, Tunisia, Hungary, Russia, Brazil, Switzerland, Bulgaria, Portugal, India, Colombia, Hong Kong and China. Most are held at 99–100%. One is indirect: BOIRON (HANGZHOU) TRADING is wholly owned through BOIRON ASIA LIMITED.

Can I access BOIRON's data through an API?
