Energy Recovery, Inc. (ERII)
The near-monopoly of seawater desalination energy recovery, sold off on a temporary Mideast guidance withdrawal. A delay-not-cancel backlog plus the PX Q650 product cycle frames a path to ~2x by mid-2028.
Thesis
- ERII is a ~98%-share monopoly in the energy-recovery device (ERD) layer of seawater reverse-osmosis desalination — >35,000 PX devices installed, ~36M m3/day produced, >$6B/yr of customer energy savings — riding a desalination capex super-cycle (~$21-24B in 2025 growing to ~$47-58B by 2030-2033, ~9-12% CAGR). The direct ERD niche alone runs ~$2.1B (2024) to ~$5.2B (2033) at 10.2% CAGR. This is a structurally advantaged, ~65% gross-margin, net-cash compounder.
- The Q1 2026 selloff is a gift, not a fundamental break. Management WITHDREW FY2026 guidance on May 6, 2026 purely on Middle East/Iran conflict timing — explicitly 'project delays will be just that' (slip 2026->2027), driven by water scarcity that 'isn't going away.' The stock is down ~20% over six months and trades at $8.82 vs. an average analyst PT of ~$15 (+70%) and highs of $19-22.
- The PX Q650 (launched Mar 2026; +63% peak capacity vs. Q400, up to 99% efficiency, 30-yr life) is a multi-year ASP/mix tailwind: first commercial order already booked, multiple large customers in design integration, becomes the primary product ~2028 — directly addressing the world's largest plants (Saudi ~9M m3/day pipeline, the $32.8M Saudi + >$12M UAE bookings).
- PATH TO 2x (~mid-2028): revenue recovery from the FY2025 $135.0M base back to/above the prior ~$145M record as delayed GCC megaprojects convert in 2027-2028 (~$150-155M), Q650 mix lifting ASP, and a re-rating of the depressed ~3.4x P/S toward the water-comp median (~4-5x). $150M x ~4.5x P/S ≈ $675M market cap ≈ $13 base / ~$17 bull — roughly a double off today's $453M cap. The current ~$15 average PT already covers +70%; the $19-22 highs reach the 2x line.
- Optionality is free: industrial/ZLD wastewater (Ultra High-Pressure PX; sales-team expansion across US/China/India/South America/Taiwan) is a genuine second leg, and the CO2 retail-grocery wind-down (Feb 2026) is a de-risking cost cut — neither is in the base-case number, so both are upside.
Q1 FY27 Earnings Snapshot

The Q1 2026 print was a beat that the market initially rewarded (+2.7% after-hours) before the bigger story — the temporary withdrawal of FY2026 guidance — drove the six-month ~20% drawdown. Revenue of $9.7M (+20.3% YoY vs. $8.1M in Q1'25) topped the ~$8.3M consensus by ~17%, and adjusted EPS of -$0.11 beat the -$0.13 estimate. ERII's quarterly cadence is extreme: Q1 is structurally the smallest quarter (it shipped $32.0M in Q3'25 and $38.6M in Q3'24), so the headline Q1 operating loss of $14.9M and 27.8% gross margin are seasonal artifacts of fixed opex against a thin revenue base — the full-year gross margin runs ~65% (FY2025: 87.9/135.0 = 65.1%). The substantive news was qualitative and forward-looking: (1) CEO David Moon announced his intention to retire (search underway, internal and external on the table) and CFO Mike Mancini resigned, with Aidan Ryan stepping in as interim CFO; (2) management withdrew 2026 guidance on Iran/Middle East conflict uncertainty, framing the impact as TIMING — 'our original financial guidance for 2026 is no longer reliable... the project delays will be just that... [as] we move from 2026 into 2027'; and (3) the PX Q650 'is off to a strong start,' with the first commercial order booked and multiple large customers designing it in. Net: a de-risked balance sheet (cash > debt, current ratio >10), an intact secular demand backdrop ('water scarcity... isn't going away'), and a self-inflicted-by-conflict air pocket in 2026 that we read as a 2027 catch-up rather than demand destruction.
