AI Analysis

AI-generated, general educational analysis — not personal investment advice.

Birchtech is a tiny pollution-control company selling specialty activated carbon and mercury-capture technology, with water-treatment work on PFAS/PFOS. In fiscal Q2 2026, the quarter ended 2026-06-30, revenue was $3.8M but net income was -$3.0M, a -79.6% margin; fiscal Q1 2026, ended 2026-03-31, had $4.2M revenue and -$1.3M net loss. FY2025, ended 2025-12-31, produced $17.6M revenue, -$3.0M net income, and -$0.16 EPS. The record is volatile: FY2024 lost $10.8M, while FY2023 earned $5.7M. FairStock labels it a TURNAROUND — loss in the latest year after earlier profits. That label fits, but a turnaround is not a moat. I see no durable competitive advantage in these numbers; revenue growth of 16.50% is not reaching the bottom line, with supplied profit growth of -95.70%. Financial health is mixed: debt is low at D/E 0.03, yet TTM free cash flow is -$3.8M and FCF yield is -11.8%. FairStock’s Piotroski F-score is 2/9 and Altman Z-score is -3.99. At the $1.24 close on 2026-10-26, market cap is $32.6M; FairStock P/E is -7.29, P/B is 4.00, ROE is -134.41%, and ROCE is -14.40%. Paying four times book for negative earnings and negative cash flow offers no Graham margin of safety. I would need evidence of positive cash earnings and a lower conservative valuation before calling this cheap.

In plain English: Birchtech makes special carbon products used to clean mercury and other pollutants from air and water. The business looks weak right now because it is losing money and using up cash. At $1.24, the stock does not look cheap compared with its losses and accounting value.
