A discount this large is often a warning rather than a bargain — the market may expect earnings to keep falling. See the revenue trend above.
How to read this
What today’s price assumes: owner earnings shrinking ~7%/yr over 5 years. The estimate assumes owner earnings stay flat (0% growth).
We solve for the constant annual change in owner earnings that would make the five-year zero-growth estimate equal today’s price. This keeps the existing model inputs and calculation unchanged; it is an expectations lens, not a forecast.
This zero-growth estimate assumes trailing owner earnings persist — unreliable for declining businesses. The recent FY revenue series does not trigger the three-consecutive-declines flag.
Among the current top-score group, the median current price is 239% above the zero-growth estimate across 48 of the current top 50 companies by Moat Score with both values.
Missing a usable price or zero-growth estimate: ANF, BKNG.
Model details under moat-index@3.0.0: zero-growth multiple 11.1×, capped-growth comparison at no more than 18×; 9% discount rate; high-end growth 0% (capped at 4%) using min(5y revenue CAGR, 5y diluted-EPS CAGR), clamped to 0%–4%; maintenance capex uses min(capex, D&A); abstain when D&A is unavailable. This is a disclosed model range, not intrinsic value as fact.
17 years of fundamentals
The business, in plain English
HUDSON TECHNOLOGIES INC /NY booked $247M of revenue in FY2025 in the Industrials sector and kept 25.2% of it as gross profit — a moderate-margin business by that measure. After every other cost, 6.8% of each revenue dollar reached the bottom line.
Across the filed record, revenue grew from $37.3M (FY2010) to $247M (FY2025) — about 13.4% a year compounded over 15 years.
It earned 6.7% on invested capital in the latest filed year, FY2025. Across the full 16-year measurable filed record, median ROIC was 10.5%. Over the v3 recent window (10 measurable filed years), median ROIC was 9.7%. The Returns on Capital filter above scores it 38/100.
HDSN's latest filed year, FY2025, doesn't disclose total debt in a form the methodology can use, so current leverage is treated as unmeasured — never assumed to be zero.
Put together: Balance-Sheet Safety is the strongest of the five filters (100/100) and Pricing Power the weakest (19/100), which is how HDSN lands at 50/100 — a Shallow 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.

Insider activity
Form 4 reports mix P/S market or private transactions with compensation-plan mechanics. Activity casually described as “insider selling” can include compensation mechanics; awards, tax withholding, and option exercises are shown by their exact filed class here, never collapsed into “Bought” or “Sold.”
These are disclosed filing facts and arithmetic aggregates, not a signal or verdict.

Track record
How HUDSON TECHNOLOGIES INC /NY’s moat rated in each of the years we can reconstruct from its filings — scored only on what was knowable at the time — and what its price and returns did afterward. The score never saw a price; the two are joined only in hindsight, for education, not as a signal.
Point-in-time scores 2011–2025, one methodology version · reconstructed from filings on file each Dec 31 — never with hindsight
Point-in-time Moat Score (dot colored by tier)Indexed price (total-return (dividends reinvested))Rated Wide-moat that year
How to read this: each dot is what the engine would have scored HDSN on that December 31; the line below is its total-return price path (dividends reinvested) in the years since.
Two tracks, one timeline: the score has its own 0–100 scale (top), the price its own 100-based scale (bottom) — never a shared axis. The price path is a total-return (dividends reinvested) index built from the same data the forward returns use; gaps in the score line are years with no reconstructed rating (see the table for why). The Table view carries every value.
What followed, in the years it rated Wide
In the reconstructed history shown, HDSN did not rate Wide-moat in any year, so there is no wide-moat track record to report. That absence is itself the honest answer — we don’t manufacture a comparison where the rating never earned one.

Does HUDSON TECHNOLOGIES INC /NY have an economic moat?
Based on its FY2025 SEC filings, the Moat Index scores HUDSON TECHNOLOGIES INC /NY (HDSN) 49.9 out of 100 — a Shallow moat. The five questions behind that score begin at 20% each; if exactly one genuinely lacks data, the other four weights are renormalized and disclosed. revenue and EPS trend 38, pricing power 19, returns on capital 38, balance-sheet safety 100, capital allocation 55.
Is HDSN trading below the conservative owner-earnings estimate?
The value if growth stopped today — a zero-growth baseline — is $9.00 per share. It capitalizes normalized owner earnings at a 9% rate and assumes 0% growth. Versus a recent price of $6.34, that is 30% below value if growth stopped today. The model also publishes a capped-growth comparison, but the zero-growth estimate is the cautious baseline. It assumes trailing owner earnings persist and is unreliable for declining businesses. This is an educational estimate from primary SEC filings, not intrinsic value as a fact or investment advice.
How has HDSN's Moat Score changed over time?
The record logs 15 readings since Jul 17, 2026; the latest reads 49.9 out of 100 (shallow moat). No tier changes on record yet. (Methodology or normalizer upgrades on Jul 20, 2026, Jul 23, 2026, Jul 26, 2026 re-based the score; readings across versions aren't compared.) The history is append-only — readings are only ever added, never rewritten.
