Loss: no P/E
Operating margin is operating income as a share of revenue. Free cash flow is cash from operations minus capital spending. Return on equity is net income as a share of shareholders' equity. Market cap is the last closing share price times the latest diluted share count, so it is approximate. P/E is the last close divided by diluted earnings per share over the last four quarters, or the latest fiscal year where the quarters aren't available; there is none when the company made a loss.
About these figures. In fiscal 2026 the SEC's structured data shows assets that differ from liabilities plus equity by more than 3%, so total liabilities may be incomplete. Return on capital for fiscal 2026 is blank: invested capital is small next to total assets (cash nearly matches equity and debt), so the ratio isn't meaningful. Piotroski F-score for fiscal 2026 is blank: the 10-K's structured data doesn't include every figure it needs.
Charts show fiscal years, from the 10-K filings.

From fiscal 2017 to 2020, earnings per share fell 56.3% a year and net income 51.1% a year, as new shares raised the share count by 27% and diluted each share's earnings. LightPath Technologies then lost money in fiscal 2021, 2022, 2023, 2024, 2025 and 2026.

US$ millions unless stated, at each fiscal year end. Net debt to EBITDA is debt minus cash, divided by operating income before depreciation and amortization: roughly how many years of those earnings the net debt equals. Debt to equity is debt as a multiple of shareholders' equity. Interest coverage is operating income divided by interest expense. The current ratio is current assets over current liabilities; the quick ratio leaves out inventory.

The latest 12 of 18 trades. Open-market purchases and sales by officers, directors and 10% owners, from their Form 4 filings with the SEC: one row per person, day and filing, at the day's average price. Grants, option exercises and shares withheld for tax aren't counted. Insiders buy and sell for many reasons, such as taxes, spreading their savings or a plan set up months earlier, so a trade on its own says little about where a company is heading.

Indicators
Four widely used measures, worked out from the company's filings. The cutoffs are the ones their authors or users go by, not a verdict of ours.
| Indicator | FY24 | FY25 | FY26 |
|---|---|---|---|
| Piotroski F-score | 3 of 9 | 3 of 9 | — |
| Rule of 40 | −8.9% | −8.5% | 69.8% |
| Altman Z'' | −12.93 | −8.78 | 3.01 |
| Accruals ratio | −16.8% | −10.1% | −7.5% |
Piotroski F-score: how many of nine simple tests of profitability, funding and efficiency the company passed in the year (Piotroski, 2000); 8 or 9 is strong, 0 to 2 weak. Rule of 40: revenue growth plus free cash flow margin; software investors treat 40% or more as the bar. Altman Z'': working capital, retained earnings, operating income and equity weighed against assets and liabilities (Altman, 1995); Altman puts above 2.6 in the safe zone and below 1.1 in the distress zone. Accruals ratio: net income minus cash from operations, over average total assets; lower means profit is backed by cash.
