Ermenegildo Zegna N.V., also known as Zegna Group (Italian pronunciation: [ˈdzeɲɲa]) or the Ermenegildo Zegna Group, is an Italian luxury fashion house headquartered in Milan. It was founded in 1910 by Ermenegildo Zegna in Trivero, Biella, in the Piedmont region of northern Italy. It is led by the Zegna family and is one of the most renowned Italian men’s clothing businesses internationally. As of 2021, it is a public company that is listed on the New York Stock Exchange.

The origins of the family business date back to the late 19th and early 20th centuries, when Michelangelo (Angelo) Zegna (1859–1923), a watchmaker from Trivero, Biella, decided to open a textile factory in the nearby town of Flecchia. In 1910, three of Angelo’s ten children, including the youngest Ermenegildo (born in 1892), along with a fourth partner, Costanzo Giardino Vitri, founded Lanificio Zegna & Giardino Vitri in Trivero in the Biellese Alps. With the early departure of Vitri and one of the brothers, Ermenegildo took the helm from the beginning, joined by his brother Mario until the early 1940s.

Zegna's vision was to create high-quality fabrics, so he began to source wool directly from several countries around the world, such as Mongolia, Australia, South Africa; he also bought modern machinery from England.

During the Interwar period, Zegna's business started to flourish. In the late 1920s, the Lanificio (wool mill) employed more than 700 workers, growing to more than 1,000 in the late 1930s. In 1938 the company began to export fabrics in the US, through its subsidiary Zegna Woollens Corporation established in New York City.

In 1942, Ermenegildo's sons Aldo (born in 1920) and Angelo (born in 1924) entered the company, which was renamed Ermenegildo Zegna and Sons. In the mid-1950s, the company employed 1,400 workers.

Ermenegildo Zegna's sons, Aldo and Angelo, took over the company in the mid-1960s. Under their guidance, the label both expanded its business to ready-made suits and established new plants and distribution networks abroad. In 1968, the first factory producing sleeve-units and trousers was opened in Novara, followed by openings in Spain, Greece, and Switzerland. Sales and marketing departments were also established in France, Germany, the U.K., and the U.S.

In 1972, Zegna launched its made-to-measure service called Su Misura.

Zegna's attention to wool quality continued through 1960s and 1970s, as the company established the Wool Awards in Australia (1963) and the Mohair Trophy in South Africa (1970).

The international development strategy run by the Zegna brothers brought to the openings of the first owned boutique in Paris in 1980, followed by Milan in 1985. In 1991 Zegna became the first luxury label to open a store in China.

During the 1990s, the third generation of the Zegna family entered the business. Angelo's son, and namesake of the company's founder, Ermenegildo "Gildo" Zegna, became CEO of the Group in 1997; his cousin Paolo became the chairman. Under their governance, the company began a strategy of brand extension and full verticalization.

From 1990 to 2020, Zegna held the majority in women’s fashion brand Agnona brand; it was subsequently sold to the Aimone family, another branch of the Zegna family, with the Zegna group keeping 30 percent.

In 1991 Zegna was the first luxury brand to enter the China market, with a flagship store in Beijing; and one of the first to access the Indian market.

In 2008, the Group established its new headquarters in Milan, in a building designed by architects Antonio Citterio and Gianmaria Beretta.

Starting from the late 1990s, the Group has undertaken a series of acquisitions of Italian and foreign companies that have expanded its business scope and now form the “Filiera”, a unique, company-owned and controlled entity, comprising selected Italian textile producers, integrated with the distinctive manufacturing capabilities of luxury, ensuring excellence, quality, and innovation.

In 2009, the Ermenegildo Zegna Group acquired a majority stake in Tessitura di Novara, a company specialized in high-quality silk weaving.

In 2012, it acquired a minority stake in Pettinatura di Verrone, a company specializing in the combing of fine wools and natural fibers.

In 2014, Zegna acquired the majority of Achill, an Australian wool farm counting about 12,500 sheep in its flock.

In 2016, the Group acquired a majority stake in Bonotto, a high-end textile manufacturer based in Molvena, Vicenza, giving the Group the possibility to explore new areas such as furnishing and experimental fabrics.

Two years later, Zegna – through its subsidiary ZECA company – took over the historic Cappellificio Cervo hat-maker.

In 2018, Zegna – already present in India with three stores – together with Reliance, acquired a stake into Indian fashion designer Raghavendra Rathore's firm. In the same year Zegna announced that they purchased 85% of the eponymously named Thom Browne, a New York City-based menswear and womenswear brand, founded in 2001.

In 2019, Zegna bought a 65% stake of Italian jersey fabrics manufacturer Dondi, increasing its control over the textile supply chain.

In June 2021, the Zegna Group bought a 60% majority stake in Tessitura Ubertino, a high-end fabric maker based in Piedmont. A few weeks later, Zegna also bought a 40% share in Tessitura Biagioli Modesto, an Italian spinning mill specialized in cashmere production.

In 2023, the Prada Group and the Ermenegildo Zegna Group announced an agreement to acquire a minority stake in Luigi Fedeli e Figlio S.r.l., an Italian family-owned company founded in 1934 in Monza, now in its third generation, recognized worldwide as an excellence in Made in Italy knitwear in fine yarns.

In 2021, Zegna agreed to go public by combining with a US special-purpose acquisition company launched by European private equity group Investindustrial.

On December 20, 2021, the Zegna Group went public in New York with a valuation of $3.1 billion and a market capitalization of $2.4 billion . It is the first Italian fashion company to be listed in New York.

The Zegna family retains control of the company with more than 60% of the capital, held directly by Ermenegildo Zegna and the family company, Monterubello SS. Since 2022, the company’s legal headquarters have been in the Netherlands, while its operational headquarters remain in Italy.

The Ermenegildo Zegna Group operates in the market through three complementary brands: ZEGNA, Thom Browne, and TOM FORD FASHION.

ZEGNA was founded in 1910 as a textile company (“Lanificio Zegna”). Formerly known as Ermenegildo Zegna, in 2021, in parallel with the Group's stock market listing, the brand name became simply ZEGNA. A new logo was also adopted, referencing the road from which it all began, in homage to the founder’s vision and commitment, who in the 1930s promoted the construction of the provincial road 232 Panoramica Zegna, crossing the company’s original territories.

In 2003 Zegna entered the fragrance market. Over the years, it has also signed partnerships with other major brands such as Maserati, Marcolin and Real Madrid.

Since June 2016, the artistic director of ZEGNA has been Alessandro Sartori, who is entrusted with the creative functions of all ZEGNA brands.

In 2021, Zegna branded products accounted for 66% of Group revenues.

Thom Browne is a New York City-based luxury fashion brand, founded by American designer Thom Browne in 2001. Ermenegildo Zegna Group acquired an 85% stake in Thom Browne in August 2018, at a $500 million valuation. The founder retained the role of Chief Creative Officer of the company.

The brand is offered in some 300 stores in 40 countries; in 2021, it accounted for 20% of Group revenues.

As of April 29, 2023, following completion of the acquisition of Tom Ford International, Ermenegildo Zegna Group acquired from Estée Lauder the license for the Tom Ford brands for men’s and women’s lines, accessories, lingerie, fine jewelry, children’s clothing, home textiles, and design products. The contract has a twenty-year term and includes an automatic renewal for an additional decade.

The Ermenegildo Zegna Group controls the entire value chain of its products, from the purchase of raw materials through fabric production to the design and sale of finished products. The Group controls and participates in nine companies known as the Filiera, comprising Italian textile manufacturers specializing in all areas of interest.

Lanificio Ermenegildo Zegna (“Ermenegildo Zegna Wool Mill”) is located in Trivero, in the Piedmont region of Northern Italy. It was founded by Ermenegildo Zegna in 1910, when he was 18. Under the Zegna Group supervision, shorn fleeces coming from several countries are processed at the Lanificio, combining artisanal activities and modern technologies, from raw material to finishing.

Bonotto is known for following a “slow factory” model, aiming at craftsmanship and rejecting standardization and low cost chain production. Bonotto is also famous for the rich archive of its Foundation, which houses over 24,000 works of art.

Based in Sagliano Micca (Biella), Cappellificio Cervo is a historic hattery (founded in 1897) acquired by Zegna-controlled ZECA company in 2018, with the aim of relaunching it, in partnership with entrepreneur Vincenzo Caldesi and Artigiana Cappellai.

Based in the Carpi textile hub, near Modena, Dondi was founded in the 1970s as Dondi Jersey and is a renowned manufacturer of high-end knitwear for men and women.

Tessitura Ubertino is a fabric maker specialized in high-end fabrics for womenswear, such as tweed and jacquard. It was founded in 1981 by Adalgiso Ubertino and is based near Biella.

Approximately 35% of sales were generated in the EMEA region, 41% in APAC, 22% in North America, and 2% in Latin America.

In 2021, the Group has become a public company. Consequently, Ermenegildo (Gildo) Zegna, grandson of founder Ermenegildo, took on the role of chairman in addition to CEO, while his cousins Paolo and Anna Zegna joined the board of directors.

Zegna is the largest and finest quality fabric producer in the world.

The Ermenegildo Zegna Group is particularly active in corporate social responsibility, which began in the 1930s when the founder distinguished himself for promoting a series of social welfare initiatives in favor of the Trivero community.
