Elmos Semiconductor SE stock (ISIN DE0005677108) is drawing investor attention after the company agreed on a long-term wafer capacity deal with SK keyfoundry for 130nm technology on September 9, 2026, while the shares most recently closed at EUR 144.00 on Xetra on September 7, 2026 following a 2.9 percent gain versus the prior day.

Long-term wafer deal underpins chip supply

According to EQS News on September 9, 2026, Elmos Semiconductor SE and its South Korean foundry partner SK keyfoundry signed an agreement to expand their collaboration on 130nm technology and secure long-term wafer capacity.

As MarketScreener reports in its summary of the signing ceremony dated September 9, 2026, the agreement gives Elmos the ability to secure wafer production capacity for 130nm mixed-signal automotive semiconductors through 2037, ensuring stable supply for long-term customer programs.

Automotive mixed-signal positioning and MDAX role

The same report from MarketScreener highlights that Elmos is a worldwide supplier of mixed-signal semiconductors for automotive applications and that the stock is included in the MDAX and TecDAX indices, which ties the share into the broader German mid-cap and technology benchmarks.

For long-term planning, the wafer capacity agreement up to 2037 gives Elmos visibility on a key input factor over more than a decade, which is particularly relevant for automotive chip programs that often run for many years and require stable production capability.
