LightPath Q3 Revenue Surges 109% YoY, But DeepValue Remains Cautious on Valuation

What happened

LightPath Technologies reported a strong fiscal Q3 with revenue jumping 109% year-over-year to $19.1 million, gross margin expanding 700 basis points to 36%, and adjusted EBITDA remaining positive for a third consecutive quarter. The company also disclosed a record backlog of $110 million, bolstered by its recent Amorphous Materials acquisition and the strategic shift to BlackDiamond glass to replace germanium. Despite these operational improvements, the DeepValue master report maintains a STRONG SELL rating, citing a market cap of ~$599 million at last report (Jan 2026) and a history of negative free cash flow and GAAP losses. The report's base case suggests an implied value of $11 per share, well below recent trading levels, and it warns that margin expansion has not yet translated into durable profitability. While the Q3 results align more closely with the bull case scenario, the lack of GAAP net income and reliance on backlog conversion keep the risk-reward unfavorable for new capital.

Implication

The Q3 results reduce the probability of the bear case but do not invalidate the DeepValue thesis that the stock is overvalued relative to earnings power. While backlog exceeds $100M (a key increase condition), EBITDA margin has not yet reached 10%, and free cash flow remains negative. The equity raise in December 2025 provides cash but dilutes existing shareholders. Any pullback in defense spending or program delays could still derail the growth story. Therefore, until the company achieves consistent GAAP profitability and positive free cash flow, the stock remains a speculative hold rather than a buy.

Thesis delta

The strong Q3 execution and record backlog pull the company closer to the bull case scenario, but the core thesis of overvaluation persists as GAAP losses and negative free cash flow continue. The DeepValue report's increase condition (EBITDA margin >10% and positive FCF) is not yet met, so the STRONG SELL rating remains appropriate despite operational progress. Investors should monitor upcoming quarters for evidence of sustainable margin expansion and cash generation before reconsidering the position.
