Lanvin Group Resiliency was Key in 2023

Preliminary Revenues Up 1% Year-on-Year

• Revenue of €426 million for FY2023, a 1% increase over FY 2022

• Despite challenging conditions, Lanvin Group grew revenue by 8% in APAC

• Resiliency through creative transition at Lanvin brand helped improve sales trend in the second half of 2023

• Positive signals in the DTC channel, including e-Commerce are proving the effectiveness of the Group’s strategy

• Ongoing implementation of strategic plans in 2023 to drive further revenue growth and margin improvement

February 21, 2024 - Lanvin Group (NYSE: LANV, the “Group”), a global luxury fashion group with Lanvin, Wolford, St. John, Sergio Rossi, and Caruso in its portfolio of brands, today announced its preliminary, unaudited revenues for the full-year 2023. The Group achieved revenues of €426 million, a 1% increase year-over-year versus 2022.

Eric Chan, CEO of Lanvin Group, said: “2023 was a year full of macroeconomic headwinds and global challenges. Lanvin Group showed tremendous resilience and continued on its growth trajectory. 2023 was also a year that our group and our brands proved their ability to manage through adverse market conditions and execute their strategy. A softening second half saw the luxury fashion industry in a position it has not been in, in quite some time. Therefore, I am pleased to report that Lanvin Group maintained growth for the year; and I am confident in our management’s ability to continue to build upon the foundation we have built on our path to profitability.”

Selected Highlights

The Group drove results through a softening market in the second half: Lanvin Group maintained growth through a transitional year with 1% year-on-year growth. The Group continued improving its retail network and expanding its e-commerce footprint. Successful product launches and marketing campaigns generated brand heat allowing for resiliency in revenues during a challenging market.

Store network rationalization: The Group continued to rationalize its store footprint and had an overall reduction in its store-base by a total of 12 stores. Despite the smaller store base, Group DTC sales remained flat on a like-for-like basis. St. John and Sergio Rossi posted strong store like-for-like growth with 13% and 6%, respectively.

Lanvin brand showed improving result in the second half: Lanvin brand performed better in the second half of the year in spite of the increasingly softening market. The brand successfully managed through a year of creative transition, but was impacted by a softer wholesale market. The establishments of the Leather Goods and Accessories department and Lanvin Lab, with the first Lanvin Lab capsule successfully launched with the Grammy-winning artist, Future in Q4, started to make positive impacts in the second half and will continue to do so in 2024. While first half revenue decreased by 11%, the brand ended the year down 7%.

Stability in North America and EMEA, and growth in APAC despite economic challenges: Management successfully navigated an increasingly challenging market to maintain revenue growth for 2023. North America grew slightly while EMEA decreased slightly. In Asia, despite a slow start to the year in China in the first half, Greater China posted 8% growth and overall, the APAC region grew by 8%.

Continuing transition to core products and accessories: The Group continued its focus on refining products and categories to provide stability and resiliency to revenue and profitability. With a refocused strategy on their brand and product offerings, St. John grew its DTC channel by 7%, in 2023. Additionally, Caruso achieved 30% growth in global revenue by continuing to drive its playful elegance approach and expanding its production capacity and its specialized workforce.

e-Commerce revenue continued its growth trend: Digital revenue continued to grow with the Group-level posting a 3% year-on-year growth in e-Commerce. Notably, St. John showed 14% growth in e-Commerce revenue and Sergio Rossi showed 5% growth. Lanvin and Wolford remained flat for the year.

2024 Outlook

The Group anticipates that while continued softness in the overall global market will impact the business, regional economies will fare better and present opportunities for growth. Furthermore, the APAC region shows opportunities for market share gains. The Group plans to pursue tactical growth opportunities in 2024.

At both Group and brand-level, ongoing initiatives will continue to drive improved margin profile. Planned marketing initiatives and product launches are expected to drive sales in 2024 which will lead to improving scale as the Group capitalizes on the operating leverage it built in 2023.
