Natarajan Ramanan, the Chief Technology Officer at Energy Recovery, Inc. (NASDAQ:ERII), disposed of 272 shares of common stock on March 5, 2026, according to a Form 4 filing with the Securities and Exchange Commission. The shares were sold at $10.57 each, producing a total transaction value of $2,875.
The filing indicates the sale was carried out under a power of attorney, with William Yeung executing the transaction on Ramanan’s behalf. Following the sale, Ramanan is recorded as directly owning 52,565 shares of Energy Recovery.
The insider sale occurs against a backdrop of recent operating and financial developments at Energy Recovery. In its fourth-quarter 2025 results the company reported earnings per share of $0.53, below the consensus expectation of $0.64. Revenue for the quarter was $66.9 million, which missed the anticipated $82.59 million figure.
For full-year 2026 the company issued a revenue outlook in the range of $115 million to $140 million. That guidance is below the average analyst estimate of $165 million. Energy Recovery also provided adjusted earnings-per-share guidance of $0.50 to $0.70, versus the analyst projection of $0.88.
In related strategic moves, Energy Recovery said it will exit its carbon dioxide retail grocery business. The company’s updated results and outlook prompted Freedom Capital Markets to reduce its price target for Energy Recovery from $18.20 to $13.00, while keeping a Buy rating in place. Freedom cited uncertainties around the timing of megaprojects as a key consideration in its revision.
Taken together, the insider transaction, the quarterly shortfalls, downward guidance and the analyst price-target cut illustrate a period of adjustment for Energy Recovery. The company is managing weaker near-term demand and recalibrating its business footprint as it steps away from the carbon dioxide retail grocery operation.
Market indicators show the stock trading close to its 52-week low of $9.59 and reflecting a 32% decline over the past year, context that surrounds this insider sale and the company’s recent financial disclosures.
Given the limited information in the filings and public statements, the precise motivations behind the individual sale were not disclosed beyond the mechanics noted on the Form 4. The company’s reported results, guidance and strategic actions remain the principal publicly available signals for investors and analysts assessing Energy Recovery’s near-term trajectory.
