MRM
MEDIROM Healthcare Technologies Inc.
stock NASDAQ ADR

This is Himax, they are currently trading at $18.44, with a +131% gain in just 6 months.
This company is important because NVIDIA is using Co-Packaged Optics (CPO). Rather than relying on external transceivers to convert electricity into light, CPO integrates this process directly into the network switch’s housing. By utilizing TSMC’s COUPE platform and micro ring modulators (MRM), this slashes power usage by roughly 3.5x.
The Fiber Array Unit (FAU) serves as the critical physical interface for this system:
\- The COUPE engine emits laser data vertically. A prism and microlens array within the FAU must pivot these beams 90 degrees to align with horizontal fibers. Because these optical fibers are thinner than a human hair, the FAU uses a V-groove substrate to lock them into the exact position required for a seamless connection.
Himax manufactures the optical components inside this FAU (microlens arrays + prisms + V-groove substrates) using nanoimprint lithography.

There is also analyst confirmation backing this up. Digitimes, citing Tianfeng Securities analysts, reported that Himax is the sole microlens array supplier for both COUPE Gen 1 and Gen 2.
The risk: this business has a lot of automotive exposure.
Just 2 days they beat and raised guidance.
