Winston Score History

The full picture

Lightwave Logic is a technology development company working on a special type of material called electro-optic polymers. These materials can convert electrical signals into light signals extremely fast, which is useful for fiber optic communications, data centers, and high-speed internet infrastructure. The company holds patents on its polymer technology and is focused on making chips that move data using light instead of electricity.

The company does not yet sell products commercially — it earns no meaningful revenue and funds its operations through stock issuances and grants while it develops its technology. It is based in Colorado and operates entirely in the United States at this stage. Its potential moat lies in its proprietary polymer materials and patent portfolio, but the core risk is that it remains pre-revenue with deeply negative margins, meaning it must continue raising capital to survive while competing against established photonics companies and other polymer developers racing toward commercialization.

Strong grower

Lightwave Logic is growing revenue at 28% year-over-year. The Winston Score penalises unprofitable companies, but revenue at this pace tells a different story — this is a company still in "build mode."

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
