(“ENERGY RECOVERY” OR THE “COMPANY”) COMMON STOCK (TICKER SYMBOL: ERII) AS OF MAY 2, 2018, WHO CONTINUE TO OWN SUCH SHARES (“CURRENT ENERGY RECOVERY STOCKHOLDERS”).

IF THE COURT APPROVES THE SETTLEMENT AND DISMISSAL OF THE ACTION, STOCKHOLDERS OF ENERGY RECOVERY WILL BE FOREVER BARRED FROM CONTESTING THE APPROVAL OF THE PROPOSED SETTLEMENT AND FROM PURSUING RELEASED CLAIMS. THIS ACTION IS NOT A “CLASS ACTION.” THUS, THERE IS NO COMMON FUND UPON WHICH YOU CAN MAKE A CLAIM FOR A MONETARY PAYMENT. PLEASE TAKE NOTICE that this action is being settled on the terms in a Stipulation and Agreement of Settlement, dated May 2, 2018 (the “Stipulation”).1 The purpose of this Notice is to inform you of:  the existence of this derivative action (the “Action”),  the proposed settlement between the Plaintiffs and Defendants reached in this Action (the “Settlement”),  the hearing to be held by the Court to consider the fairness, reasonableness, and adequacy of the Settlement,  Plaintiffs’ Counsel’s application for fees and expenses, and  Plaintiffs’ Service Awards.

All capitalized terms not otherwise defined herein have the same meaning as set forth in the Stipulation. ENYNOT1

BASIC INFORMATION 1. Why did I get this notice package? The Superior Court of the State of California, County of Alameda (“Court”) ordered that this Notice be sent to you because you or someone in your family or an investment account for which you serve as custodian may own Energy Recovery common stock as of May 2, 2018. This Notice explains the lawsuit, the Settlement, and your legal rights in connection with the Settlement. 2. What is this lawsuit about? What has happened so far? The Action is pending before the Honorable Ioana Petrou in the Superior Court of the State of California, County of Alameda. This is a derivative action brought by stockholders of Energy Recovery and pleads claims for breach of fiduciary duty, waste of corporate assets, and unjust enrichment derivatively on behalf of Energy Recovery against the Individual Defendants, who are certain current and former officers and directors of Energy Recovery.2 The initial complaint in this Action was filed on February 18, 2016, which was consolidated with another action that was filed subsequently. The Action alleges that the Individual Defendants breached their fiduciary duties by knowingly or recklessly making and/or causing Energy Recovery to make false and misleading statements of material fact. Since the Action was commenced, Plaintiffs filed a consolidated complaint and Defendants filed a demurrer seeking to dismiss it. The Court sustained the demurrer, after which Plaintiffs filed an amended consolidated complaint, and Defendants filed a demurrer seeking to dismiss it, too. Plaintiffs had also requested that Defendants produce documents. Defendants objected to the request, and Plaintiffs filed a motion to compel the production of documents. During the pendency of the Action, the parties engaged in extensive settlement efforts including an in-person full-day mediation in October 2016. Ultimately, the parties agreed in principle to a settlement in November 2017. 3. Why is there a settlement? The Court has not decided in favor of the Defendants or the Plaintiffs. Instead, both sides agreed to the Settlement to avoid the distraction, costs, and risks of further litigation, and because the Settlement provides substantial benefits to, and is in the best interests of, Energy Recovery and its stockholders. Defendants deny each and every allegation of wrongdoing or liability arising out of or relating in any way to the events, conduct, statements, acts, or omissions alleged in the Action. Defendants further assert that, at all times, they acted in good faith, and in a manner they reasonably believed to be and that was in the best interests of Energy Recovery and Energy Recovery’s stockholders. Defendants assert that they have meritorious defenses to the claims in the Action. Nonetheless, Defendants have entered into the Stipulation, without admitting or conceding any fault, liability, wrongdoing, or damage whatsoever, in order to avoid the risks inherent in any lawsuit and the burden and expense of further litigation. 2 “Defendants” refers to individual defendants Joel Gay (current director, CEO and President), Hans Peter Michelet (current Chairman of the Board), Alexander J. Buehler (current director and former CFO), Arve Hanstveit (current director and Audit Committee member), Dominique Trempont (current director and Audit Committee Chairman), Robert Yu Lang Mao (current director and Audit Committee member), Thomas S. Rooney, Jr. (former director, CEO and President), Borja Sanchez-Blanco (former Sr. VP of Sales and VP of the mega products group), Audrey Bold (former Chief Marketing Officer), Paul M. Cook (former director), Marie-Elisabeth Paté-Cornell (former director), and Fred Olav Johannessen (former director and Audit Committee member), and nominal defendant Energy Recovery. - 2 -

4. What does the Settlement provide? The Settlement provides that, in exchange for the release of derivative claims by all Energy Recovery stockholders and dismissal of the Action, Energy Recovery will adopt, within sixty (60) days of the date the Settlement has become final, corporate governance reforms summarized below and described fully in Exhibit A to the Stipulation. These changes shall be maintained for a period of no less than four (4) years from the date the Settlement has become final. Energy Recovery acknowledges that the prosecution and settlement of the Action was a substantial and material factor for Energy Recovery in deciding to adopt and implement these changes to the Company’s policies and procedures, which are as follows:  The Company will adopt a new Regulation FD Compliance Policy;  The Company will create a Charter for the Disclosure Committee that formalizes and enhances the Disclosure Committee’s duties and responsibilities;  The Company will expand and improve its Code of Business Conduct and Ethics; and  The Company will incorporate what are currently three stand-alone documents – the Insider Trading Policy, the FCPA Policy, and the Code of Business Conduct and Ethics – into the Employee Handbook. In connection with the Court’s approval of the Settlement, the Action and all claims asserted by Plaintiffs derivatively on behalf of Energy Recovery and against the Individual Defendants will be dismissed with prejudice. The Stipulation contains the full terms of the release and discharge of claims. The Settlement, if approved, is intended to foreclose your ability to seek legal or equitable relief from the Defendants relating to the derivative claims and factual allegations in the Action. If you have questions concerning the scope of the release, or its impact, you are encouraged to seek independent legal advice. 5. How will the lawyers be paid? Plaintiffs’ Counsel has not received any payment for work in connection with the Action, nor have they been reimbursed for out-of-pocket expenses. Plaintiffs’ prosecution of the Action and participation in the settlement negotiations were substantial factors in obtaining the corporate governance reforms described above in paragraph 4. In recognition of the benefits conferred upon, and/or maintained by, Energy Recovery as a direct result of the prosecution and settlement of the Action, Energy Recovery has agreed to cause to be paid to Plaintiffs’ Counsel $350,000, subject to Court approval (the “Fee and Expense Amount”). Each of the two Plaintiffs may apply to the Court for a Service Award in the amount of $2,000 to be paid from the Fee and Expense Amount (“Service Awards”). The Settling Parties mutually agree that the Fee and Expense Amount is fair and reasonable in light of the substantial benefits conferred upon Energy Recovery and Current Energy Recovery Stockholders by the Settlement. Neither the Individual Defendants nor Energy Recovery’s stockholders are personally liable for the payment of the Fee and Expense Amount or the Service Awards. 6. How do I object to the Settlement? You can tell the Court that you do not agree with the Settlement or any part of it. You may object in writing. You may request to be heard at the Settlement Hearing whether or not you make a written objection. The Court will consider your views. IF YOU CHOOSE TO OBJECT, THEN YOU MUST COMPLY WITH THE FOLLOWING PROCEDURES.
