Daily closes. Earnings/event dots are placed inline.
Industries move in repeating boom-and-bust cycles. This shows where this stock’s industry sits in that cycle, stage by stage (recovery → expansion → supercycle → steady → deceleration → contraction), from its fundamentals (orders, revenue, capital spending), not the stock’s price.
A booming industry is a tailwind for the names in it; a contracting one is a headwind. Companies in the same industry tend to rise and fall together with the cycle, the way a tide lifts and lowers every boat in the harbor at once, so a large part of a stock’s swing can come from where its industry sits rather than from the company itself. It’s context for reading the company’s results, not a buy/sell call. Full explanation →
Environmental & Facilities Services is in steady. Describes the industry's cycle state, not a call on this stock.
The stage band shows the industry’s cycle over the chart’s timeline (each color a stage); a ▼ marks a quarter its growth inflected down — amber is an unconfirmed watch, red is confirmed the next quarter. Use “Overlay cycle on chart” to tint the price chart by stage. The industry’s fundamentals, not a signal on this stock.
Primary pillar under pressure — Move towards positive earnings and free cash flow: Comparison needs review.
View ThesisRevenue growth is slowing — up about 5% over the past year and decelerating.
View GrowthMiddle-of-the-pack management execution.
View ManagementExpectations look reasonable — what the market is pricing in sits in line with or below what analysts forecast.
View ValuationThis stock is highly volatile — it swings about 2% on a typical day and fell roughly 75% in its worst 12-month stretch.
View RiskARQ’s thesis rests on PFAS product commercialization, but its latest revenue growth was modest and earnings missed. Revenue grew 5% year over year in Q2 FY2026, when reported EPS missed consensus. ARQ trades at 1× sales versus a 3× peer median; expectations look modest versus our view. Our model puts the next-quarter miss probability near 50%. The move toward positive earnings and free cash flow remains unverified. Peer multiples imply a price about 66% above where it trades; the thesis is on watch. This read is provisional.
Trailing returns as of 2026-10-30. ARQ is total return (includes dividends); the S&P 500 benchmark is price return (the index excludes dividends).

A consensus fair price across 2 valuation methods, at three horizons. As of 2026-10-29. Estimates are diagnostics, not price targets. Short-horizon estimates are close to coin-flips, so confidence is a method-agreement read, not a prediction.
Today's peer multiple on trailing earnings, with no growth credited. This is the headline read.
Adds projected growth, so it leans optimistic by design. Read it as upside context, not a base case.
