Vertical Aerospace Ltd. announced a long‑term supplier agreement with Syensqo on December 8 2025, securing advanced composite and adhesive materials for its VX4 eVTOL aircraft. The partnership will see Syensqo’s high‑performance composites integrated throughout the VX4 structure, providing the lightweight strength and durability required for high‑cycle operations.
The deal aligns with Vertical’s strategy of partnering with Tier‑1 aerospace suppliers such as Honeywell and Aciturri, and it strengthens the company’s supply‑chain resilience. By locking in a dedicated source of advanced composites, Vertical can reduce aircraft weight, improve performance, and lower manufacturing costs—critical factors for meeting its 2028 certification target and subsequent commercial launch.
Vertical’s Flightpath 2030 strategy, launched in November 2024, targets market leadership by the decade’s end and includes a high‑margin battery‑as‑a‑service model by 2035. The company currently holds a pre‑order book of roughly 1,500 VX4 aircraft across four continents, underscoring the commercial momentum behind the program.
CEO Stuart Simpson said the partnership is a vital step in bringing the VX4 to market. “Deepening our collaboration with Syensqo as our advanced‑materials supplier is a key milestone that will accelerate the VX4’s path to full‑scale production,” he noted.
The market reacted positively to the announcement, reflecting investor confidence in the de‑risking event. The partnership also dovetails with Vertical’s broader industrialisation plan, as Aciturri will manufacture the VX4 airframe and Syensqo’s materials will be critical to achieving the aircraft’s performance and certification goals.
Syensqo is a global leader in advanced composites, and its collaboration with Vertical complements the company’s existing relationships with other Tier‑1 suppliers, positioning the VX4 for a competitive entry into the advanced air mobility market.
