Schott AG

Schott AG is a German multinational glass company specializing in the manufacture of glass and glass-ceramics. Headquartered in Mainz, Rhineland-Palatinate, Germany, it is owned by the Carl Zeiss Foundation. The company's founder and namesake, Otto Schott, is credited with the invention of borosilicate glass.

History

Founding

In 1884, Otto Schott, Ernst Abbe, Carl Zeiss and his son Roderich Zeiss founded the ''Glastechnische Laboratorium Schott & Genossen'' (Glass Technical Laboratory Schott & Associates) in Jena, Thuringia, Germany which initially produced optical glasses for microscopes and telescopes. In 1891, the Carl Zeiss Foundation, founded two years earlier by Ernst Abbe, became a partner in the glass laboratory. Jena glass, an early borosilicate glass, was one of its early manufactured products. Otto Schott's invention of borosilicate glass, resistant to chemicals, heat and temperature change, paved the way for new technical glasses for thermometers, laboratory equipment and gas lamps.

The company experienced economic success. The workforce had grown to 1,233 by 1919. Sales had doubled to 28 million marks by 1920. Otto Schott transferred his shares to the Carl Zeiss Foundation in 1919, fully rendering the glass laboratory a foundation company and renaming it ''Jenaer Glaswerk Schott & Gen'' (Jena Glassworks Schott & Assoc.). Erich Schott, the founder's son, took over management of the glass factory in 1927. Erich Schott founded new production areas for specialty glass components used in electrical engineering as well as heat resistant borosilicate glassware for household use.

Split

In the midst of Germany's political division after World War II, the Jena factory was expropriated and transformed into a Publicly Owned Enterprise (VEB) in 1948. The company was divided in half: ''VEB Jenaer Glaswerk'' in Jena in East Germany, later integrated into the ''VEB Carl Zeiss Jena collective'', and ''Jenaer Glaswerk Schott & Gen'' in Mainz in West Germany. While ''VEB Jenaer Glaswerk'' developed into a specialty glass supplier in the Eastern Bloc, the other half developed into an international group in Mainz with sales offices abroad. The company became a specialist glass manufacturer with products including glass components for television tubes, fiber optics for light and image conductors, mirror substrates for giant telescopes, glass-ceramic cooktop panels (serial production from 1973) and glass tubes for parabolic trough power plants. Following the German reunification, the Mainz plant assumed Jena's company shares.

Late 20th century

The company experienced growth in the first decade after the fall of the Berlin Wall. ''Schott Glas'', as it became known in 1998, developed into a technology group with 80 companies in 32 countries and global sales of over 3 billion Deutschmark. Schott had been operating at only 40 sites in ten countries with global sales of DM 1.31 billion in 1984. In 2004, Schott Glas converted from a dependent enterprise of its sister enterprise Carl Zeiss (Oberkochen) to become a legally independent ''Aktiengesellschaft''—Schott AG. The Carl Zeiss Foundation remains the sole shareholder of Schott AG. The Foundation Statute does not permit to sell its shares, ruling out the prospect of an IPO.

Solar industry

The technology group entered the solar industry in 2001, founding ''Schott Solar GmbH'' in 2005 (renamed Schott Solar AG in 2008).
In 2008, Schott announced that it planned to produce crystalline photovoltaic cells and modules with a total of 450 MW annually. It also planned to produce thin-film PV wafers with a capacity of 100 MW. In 2009, the company inaugurated a US$100 million solar manufacturing facility in Albuquerque, New Mexico, USA to build solar receivers for concentrated solar thermal power plants (CSP) and 64 MW of photovoltaic modules. They had already been making 15 MW of photovoltaics annually in Billerica, Massachusetts, until the factory was closed in 2009.
The company was also engaged in concentrated solar power technology, by manufacturing solar receiver tubes.
In June 2012, Schott announced that its Albuquerque plant would close down, laying off all photovoltaic cell manufacturing employees immediately and ramping down the remaining employees over the rest of the summer. Schott withdrew from its solar business in 2012 and Schott Solar AG was dissolved.

Company profile

Torsten Derr is the company's CEO. He took over in January 2025 from Frank Heinricht, who had held the position from 2013 to 2024.

SCHOTT reported sales worth 2.05 billion Euros in its fiscal year 2016–2017. In 2017–2018 sales increase to 2.08 billion euros with an annual profit of 208 million euros. In 2019, SCHOTT reported sales worth 2.2. billion Euros with an annual profit of 206 million euros. SCHOTT AG employs around 16.200 people in production and sales facilities in 34 countries, including around 5,800 in Germany (as of 2019). SCHOTT increased its global sales by 2.2% in 2020 to reach US$2.5 billion, with an improved operating profit (EBIT) of US$320 million. The number of employees rose to around 16,500.

The sole owner of Schott AG is the Carl Zeiss Foundation, which holds all shares and is partly financed from the dividends.

Operations

Schott's corporate headquarters and largest site is located in Mainz, Germany. Its main business regions are Europe, North America, and Asia. In Europe, it operates production sites in six locations in Germany, as well as in the Czech Republic, Finland, France, Hungary, Italy, Switzerland, and Turkey. In addition to its North American corporate office in Rye Brook, New York, it has six US production sites in Duryea and Lebanon, Pennsylvania; Southbridge, Massachusetts; Louisville, Kentucky; Vincennes, Indiana; and Phoenix, Arizona. In Asia, Schott has productions in India, Malaysia, and China.

Products

Schott produces products made of specialty glass, glass-ceramics, and polymers for industries such as home appliances, pharmaceuticals, electronics, semiconductors, optics, life sciences, automotive, aerospace and astronomy.

In the consumer market, glass-ceramics from Schott are used in cooktops for electric, gas, and induction cooking under the brand name CERAN.

In industry, its glass-ceramic Zerodur is used in microlithography and as mirror substrates for large optical telescopes such as:

* European Southern Observatory’s Very Large Telescope and Extremely Large Telescope in Chile,
* Gran Telescopio Canarias in Spain,
* Keck I and II telescopes at the W.M. Keck Observatory in Hawaii.

Other applications include flat glass for home appliances, components for consumer electronics and semiconductor manufacturing. It also produces glass and filters with applications in digital cameras, laser optics, machine vision, and metrology. Some of its more recent applications include ultra-thin and flexible cover glass for smartphone displays and glass wafers for augmented reality.

Schott's subsidiary Schott Pharma develops and produces pharmaceutical packaging such as ampoules, cartridges, syringes, and vials.
