As a Buffett/Graham-style investor, I look first for a durable business earning consistent profits. Nuburu fails that test. It sells high-power blue lasers, but in fiscal Q2 2026, the quarter ended June 30, 2026, revenue was only $524,927, with a net loss of $6.5 million. In fiscal Q1 2026, the quarter ended March 31, 2026, revenue was $407,644 and net loss was $459,898. These are tiny numbers. The company has lost money in each of the last four years, so FairStock assigns no Peter Lynch category. In fiscal year 2025, the year ended December 31, 2025, net loss was $79.1 million; in fiscal year 2024, the year ended December 31, 2024, net loss was $34.5 million; and in fiscal year 2023, the year ended December 31, 2023, net loss was $20.7 million. Revenue for fiscal year 2025 was not available in the filed figures; in fiscal year 2024, revenue was $152,127. The balance sheet is the bigger worry. FairStock calculates debt-to-equity of 4.04, ROCE of -49.69%, an Altman Z-Score of -4.26, and trailing free cash flow of -$27.2 million, a -45.3% FCF yield. That is a cash-consuming enterprise dependent on external capital. At the 2026-10-13 close of $0.99, FairStock computes P/B of 0.59 and P/E of -1.71. The $60 million market cap may look low versus book value, but negative earnings and cash flow mean book value can erode quickly. The 52-week range of $0.03 to $2.95 shows extreme volatility. A true moat is unproven; the technology may be promising in EV batteries, medical devices, and defense, but commercial adoption is not yet visible in revenue. Unless revenue scales materially and cash burn reverses, this is speculation, not a value investment. FairStock Score is 13/100.

In plain English: Nuburu makes powerful blue lasers for industrial welding and 3D printing, and it also works on defense-related systems. The business looks weak: it has lost money for years, brings in very little revenue, and spends more cash than it takes in. At the recent $0.99 close, the whole company is valued at $60 million, which is below its stated accounting net assets, but that low-looking price comes with very high financial risk.
