What ST Group does

ST Group is a French industrial company specializing in high-performance composite materials for aerospace and defense applications. The company manufactures complex composite parts — including structural components used in commercial and military aircraft — and supplies them as a Tier 2 supplier to major aerospace OEMs such as Airbus and Dassault Aviation. Its core competency is producing complex-geometry composite components that meet the weight, strength, and certification requirements of modern aerospace platforms, with operations based near Toulouse in France's principal aerospace cluster.

The company's go-to-market is sales-led, built on direct B2B relationships with OEMs and aerospace systems integrators rather than broad marketing campaigns. Revenue is generated through contract-based composite parts manufacturing, with current scale at €3M in 2025 (up 18.7% year-on-year) and a public target of €11M by 2030. Strategic customer engagements include an exclusive contract with Aerotec & Concept (Expleo Group) for the KEPPLAIR 72 firefighting bomber conversion program — an ATR 72-to-firefighting-bomber conversion targeting first delivery by end-2026/early-2027 with approximately €5M in lifetime revenue potential — and a broader forecasted pipeline of approximately €59M over the next decade from aerospace, defense, and space programs.

In April 2026, ST Group conducted Europe's first fully on-chain IPO on the Lise Lightning Stock Exchange, a blockchain-powered platform backed by BNP Paribas, CACEIS (Crédit Agricole), and Bpifrance, with Allinvest Group acting as financial adviser and bookrunner. The listing, conducted under the EU's DLT Pilot Regime, represents the company's first public capital raise and is intended to fund its 2030 growth ambitions. The company is privately held with 251–500 employees and is incorporated in France.
