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

  1. 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.
  2. 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.
  3. 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).
  4. 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.
  5. 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.
