AeroEdge Co., Ltd., the Tochigi Prefecture manufacturer of titanium-aluminide turbine blades for the CFM International LEAP engine, disclosed in its annual securities report for the year to June 2026 that its supply-share agreement with Safran Aircraft Engines is set to expand from January 2028.
Under the contract, most recently updated on November 20, 2025 and running through December 2034, AeroEdge currently supplies 40% of the titanium-aluminide low-pressure turbine blades Safran needs to build LEAP engines. From January 2028 that share rises to what the filing calls the high-40s per cent range, covering both the blades AeroEdge machines from Safran-supplied material and a newly developed alloy the company is bringing into production.
| Period | Machined-blade share | New-material share |
|---|---|---|
| Through June 2026 | 40% | Not yet supplied |
| From July 2026 | 40% | Gradually rising to a maximum of 40% |
| From January 2028 | High-40s per cent | High-40s per cent |
AeroEdge is also developing its own titanium-aluminide alloy, working with Japan's National Institute for Materials Science, to cut reliance on the single European supplier that currently provides the raw material. New-material output is scheduled to begin gradually from July 2026, ramping toward the same high-40s per cent share as the existing machined-blade business by January 2028. AeroEdge says it will become the first company worldwide to handle titanium-aluminide LEAP blades from raw-material production through to finished parts.
The stakes are high for a company this dependent on one customer. Safran accounted for ¥4.93bn of AeroEdge's ¥5.08bn in sales for the year to June 2026, or 97% of revenue, and the filing's risk section lists several conditions under which the contract could end or AeroEdge's share be cut: if AeroEdge breaches the contract or becomes insolvent, if its controlling shareholder becomes a Safran competitor, if the LEAP engine business changes hands, if Safran executes an offset transaction, or if a rival matching AeroEdge's market share and geography emerges with superior price, quality or production capacity that AeroEdge cannot match. For now, the higher share remains a scheduled 2028 step, not a change already reflected in AeroEdge's order book.
