The business, in plain English

Lightwave Logic, Inc. booked $236855 of revenue in FY2025 in the Materials sector and kept 97.1% of it as gross profit — a high-margin business by that measure. After every other cost, −8576.5% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $3200 (FY2010) to $236855 (FY2025) — about 33.2% a year compounded over 15 years.

It earned −291.4% on invested capital in FY2025, with a median of −298.1% across 12 filed years. The Returns on Capital filter above scores it 0/100.

LWLG's filings don't disclose total debt in a form the methodology can use, so leverage is treated as unmeasured — never assumed to be zero.

The share count rose 191.2% between FY2012 and FY2025 — existing owners have been diluted over the record. Capital Discipline scores it 24/100.

Put together: Pricing Power is the strongest of the four filters (70/100) and Returns on Capital the weakest (0/100), which is how LWLG lands at 37/100 — a None moat.

This breakdown is generated from the filed numbers and sub-scores above — no outside narrative, no estimates. Where a filing doesn’t disclose an input, the sentence that would need it is omitted instead of guessed.
