History

Since its foundation on 29 July 1933, Faes Farma—specializing in the pharmaceutical industry—has been one of the foremost chemical companies in Biscay. Its original 4,000 m² plant on the banks of the Ibaizábal River in Lamiaco produced bismuth salts, chlorides and yellow mercury oxide from minerals sourced in Córdoba, Spain and Almadén.
Early therapeutic efforts targeted endemic conditions such as syphilis, recurrent fevers and Malta fever. Its flagship product was NEO‑FAES, selling 300 000 units in its first year. During the post‑Civil War autarky period, FAES was Spain’s sole producer of arsenobenzoles and other antiluetic arsenicals—early antibiotic agents—marketing SULFO‑FAES, CALCIO‑FAES and URO‑FAES.
In the 1940s the company added sulfopyridine, sulfathiazole and arsenoxide to its portfolio, and began processing saccharin and barium salts for radiology. During the 1950s–60s it produced herbicides and pesticides such as camphor‑chloride, polychlorocamphene and dinitronaphthalene, but from the 1970s refocused on pharmaceuticals—manufacturing 73 different medicines across therapeutic areas—and in 1978 synthesized hydrosmin.
International alliances began in the 1990s. In 2007 Faes Farma diversified into animal nutrition and health with the purchase of Ingaso, followed in 2017 by acquisitions of Initial Technical Foods and Tecnovit.
In June 2025 Faes Farma reinforced its ophthalmology portfolio by acquiring Portuguese specialist Edol for €75 M and Italian ophthalmic company SIFI for €270 M—the largest acquisition in its history—raising ophthalmology to nearly 20% of group revenues.

Facilities

The original 1935 production and office buildings were designed by Enrique Belda and later expanded in the 1950s–70s by Rafael Fontán, Pedro Ispizua Susunaga, Gregorio Viteli and Francisco Javier Ispizua Uribarri. The complex is arranged in pavilions around internal plazas, with reinforced concrete structures and brick façades featuring classical decorative elements.

Derio Plant

In mid‑2024 Faes Farma completed a new 60 000 m² factory at the Bizkaia Science and Technology Park, built for €200 M to double—and potentially triple—production capacity. Since January 2025 it has EU authorization as a pharmaceutical laboratory and production center, with gradual transfer from Lamiaco scheduled through 2027 to reach 100 million units per year. The plant features one‑third production area and two‑thirds logistics—including a robotic warehouse—and was designed with abundant natural light to enhance the work environment.
