Lightwave Logic Inc is a specialty materials and intellectual property company focused on the development and commercialization of proprietary electro-optic (EO) polymer materials designed to enable high-speed optical modulators for data communications and other photonic applications. Its Perkinamine family of EO polymers is designed for integration into silicon photonics (SiPh) and other photonic integrated circuit (PIC) platforms, supporting high-speed optical modulation with lower drive voltage requirements compared with some conventional silicon-based and III-V compound semiconductor approaches. The company operates as a single reportable segment.

Sandisk is one of the five largest suppliers of NAND flash memory semiconductors globally. Sandisk is vertically integrated, producing substantially all of its flash chips at manufacturing sites across Japan via a joint-venture framework with Kioxia. Sandisk then repackages most of its chips into SSDs for consumer electronics, external storage, or cloud storage. Sandisk was formerly a piece of Western Digital for nine years (after being acquired in 2016) and was spun off as an independent company in 2025.
