ERI0340_2024 Proxy Cover_v1r0_FNL_Front.jpg
Dear Fellow Stakeholders,
In 2023, we had another record year
with annual revenue of over $128 million –
our 9th year of consecutive revenue
growth.  We have a healthy core business in
desalination.  Our wastewater business is
beginning to show promise, nearly doubling
in size in 2023.  We continue to strengthen
our balance sheet as we generate more
cash. And we are achieving all of this based
on our pressure exchanger technology,
which has demonstrated potential to grow
in other verticals, such as CO2 refrigeration.
Energy Recovery’s strong foundation and
prospects for even greater growth are what
originally drew me to the company.  We are
proud of the fact that our PX® Pressure
Exchanger® (“PX”) creates such substantial
financial and environmental value for our
customers, andfranklyfor the world.
I firmly believe our strategy of PX-based
diversification and growth is the right path
forward, and I have been focused squarely
on making sure we continue to capitalize on
this potential since taking on the CEO role
last Fall.
As we look forward to 2024, we
anticipate a 10th year of growth in our water
business with expected revenue between
$140 to $150 million.  Our desalination
customers are starting to embrace the PX
Q400, our newest top-of-the-line energy
recovery device for desalination, which we
launched only 18 months ago.  We expect
up to half of our mega project desalination
revenue will come from the PX Q400 this
year, double what we had initially
projected. The early success of this product
shows we continue to be a marketleader in
the industry.
While growth has already been
robust, we aim to once again potentially
double our wastewater revenue, which
could comprise up to 10% of our overall
water sales.Not only have we hit our
targets in wastewater, but we are selling
into a diverse set of geographies and
industries.  This multi-industry capability,
which has been proven in the field over the
last few years, clearly demonstrates the
versatility of the PX and is a strong
foundation for future growth in this
business.
In CO2 refrigeration there are two
main milestones I hope to achieve this year:
performance testing improvements to the
PX G1300® design, and 30 to 50 new
installations in the U.S. and Europe.  We
have been steadily building relationships
with manufacturers and large, influential
supermarket chains in both the U.S. and
Europe.
This year we are also working on
moving into the next phase of our
sustainability strategy.  Sustainability has
always been part of Energy Recovery’s DNA,
and I remain committed to this in the
products we develop and produce, as well
as in our own internal operations.  We have
already achieved several of our major

2024 Proxy Statement

sustainability goals, and we must continue
challenging ourselves to do better.  In 2023,
we announced our first ever corporate
emissions reduction target and conducted a
new materiality assessment, a process in
which many of you participated, to help
guide the refinement of our goals.Your
feedback will directly contribute to Energy
Recovery’s new sustainability goals, which
we plan to publish by the end of the year.
Importantly, this year I am also
focused on further building out the long-
term growth strategy that will guide us for
the next three to five years, what I call our
“playbook.”  Energy Recovery has come a
long way in developing and executing our
diversification strategy.  Since that strategy
was laid out a few years ago, the
desalination market has continued to
evolve to the point where we are now
competing in new geographies within an
evolving competitive landscape, all of which
creates new risks and opportunities for our
foundational business.  We have found
tremendous initial success in wastewater,
and now we must focus on where to invest
to continue to grow this business at an
accelerated rate in the coming years.  And
as we set the foundation for growth in CO2
refrigeration, we must take a hard look at
how this business will develop and grow in
the next three years, as well as where to
invest to tackle other adjacent verticals in
the future as we show success.
I am optimistic about Energy
Recovery’s future, which is one reason why
I took this job.  The foundational aspects of
Energy Recovery that have attracted so
many new shareholders to our company in
recent years remain intact, and we now
must execute to deliver on this future.
Energy Recovery was built upon a solid
foundation of groundbreaking technology
30 years ago, and today we are poised for
decadesof innovation and delivering
financial and environmental value to our
customers, investors, and all of our
stakeholders.

Phased Declassification of the Board of Directors over Three-Year Period (Proposal No. 1)

The Board of Directors (the “Board”) has directed the submission for stockholder approval an amendment to the Company’s Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”) to declassify our Board over a three-year phase out period, which when completed will allow for the election of all directors on an annual basis, beginning with the 2023 Annual Meeting of Stockholders. This requires the affirmative vote of the holders of at least 66 2/3% of the voting power of the then outstanding shares of the Company, voting together as a single class. We recommend that our stockholders approve the amendments to the Certificate of Incorporation at the Annual Meeting.

2021 Director Nominee (Proposal No. 2)

Mr. Ole Peter Lorentzen, a Class I director, has notified the Board that he intends to resign upon the conclusion of his current board term and will not stand for re-election at the Annual Meeting. The Nominating and Corporate Governance Committee and the Board have nominated Olav Fjell for election as a Class I director. Our director nominee has demonstrated his commitment to diligently executing his fiduciary duties on behalf of our stockholders, and we recommend that our stockholders elect the nominee at the Annual Meeting. As a publicly traded company with a principal executive office in California, the Company is subject to the requirements of California Senate Bill 826, which was signed into law on September 30, 2018 (“SB 826”). Under SB 826, the Company was required to have a minimum of one female director by December 31, 2019 and is required to have at least three female directors by December 31, 2021. While the Company was in compliance with SB 826 as of December 31, 2020, the Company will need to increase female representation on the Board prior to December 31, 2021 to meet the requirements of SB 826. The Company intends to fill the Class I director vacancy with one female director prior to December 31, 2021 and will add an additional female director in order to satisfy such requirements.

Ratification of Appointment of Deloitte & Touche LLP (Proposal No. 3)

The Board has directed that Deloitte & Touche LLP’s (“Deloitte”) appointment for the fiscal year ended December 31, 2021 be submitted to our stockholders for ratification at the Annual Meeting. Deloitte is well qualified as our independent registered public accounting firm and has a deep understanding of our operations and accounting practices. The Audit Committee considered the qualifications, performance and independence of Deloitte, the quality of its discussions with Deloitte, and the fees charged by Deloitte for the level and quality of services provided during 2020 and determined that the reappointment of Deloitte is in the best interest of the Company and its stockholders. For these reasons, we recommend that our stockholders ratify the appointment of Deloitte as the Company’s independent registered public accounting firm at the Annual Meeting.

Approval of Executive Compensation on an Advisory Basis (Proposal No. 4)

Our CEO and other executive officers have demonstrated their commitment to fair pay and pay for performance. We are committed to effective compensation governance, as demonstrated by the following compensation policies and practices:

What We Do

What We Dont Do

✔  Substantial Portion of Compensation is At-Risk

✘  No Repricing

✔  Long-Term Vesting

✘  No Gross-Ups

✔  Stock Ownership Guidelines

✘  No Excessive Perquisites

✔  Double Trigger Change in Control

✘  No Executive Retirement Plan Benefits

✔  At-Will Employment of Executive Officers

✘  No Guaranteed Bonuses

✔  Independent Compensation Committee

✘  No Excessive Severance

✔  Independent Compensation Consultant

✔  Risk Assessment

✔  Claw-Back Policy

For these reasons, we recommend that our stockholders approve the advisory vote on the compensation of our executive officers at the Annual Meeting.

Stockholder Engagement and Governance Highlights

We believe that strong corporate governance includes consistent engagement with our stockholders. We engage with stockholders on a variety of topics throughout the year to ensure that we are addressing questions and concerns and to seek input on policies and practices. Our management team, including our CEO, Chief Financial Officer (“CFO”) and VP of Investor Relations, regularly engages in meaningful dialogue with our stockholders through quarterly earnings calls, industry conferences and other channels of communication, which we regularly share with the Board. Stockholders may communicate with our Board as set forth under “Communications between Stockholders and Directors” on page 27.

In addition, our Board regularly assesses and refines our corporate governance policies and procedures to take into account evolving best practices and the valuable feedback of our shareholders and other stakeholders who have provided important external viewpoints that inform our decisions and strategy. For example, at this year’s Meeting, Proposal 1 involves the phased declassification of our Board over a three-year period. Other governance highlights include:

✔  Proxy access rights for shareholders

✔  One class of outstanding shares with each share entitled to one vote

✔  Independent oversight  6 of 7 directors are independent (all except the CEO)

✔  Independent Lead Director with robust responsibilities

✔  100% independent Board Committees

✔  Active Board oversight of the Companys strategy, risk management and ESG

✔  Focus on diversity  goal of adding two additional female directors in 2021

✔  Prohibition on hedging or pledging Company stock

✔  Stringent new clawback policy

✔  Rigorous director and executive stock ownership guidelines

Stockholder Engagement and Governance Highlights
The Company believes that strong corporate governance includes consistent engagement
with its stockholders.  The Company believes in fostering long-term relationships and year-
round, open and honest engagement with its investors, which is critical to the Company’s
success.  The Company engages with stockholders on a variety of topics throughout the year to
ensure that it is addressing questions and concerns and to seek input on policies and practices.
The Company’s management team, including its Chief Executive Officer (“CEO”), Chief Financial
Officer (“CFO”) and VP of Investor Relations, regularly engages in meaningful dialogue with the
Company’s stockholders through 1-on-1 meetings, quarterly earnings calls, industry
conferences and other channels of communication, which the management team regularly
shares with the Board.  Stockholders may communicate with the Board as set forth under
During 2023, the Company engaged with a wide cross section of shareholders (who
collectively owned approximately 54% of the Company’s outstanding stock) through 14 investor
(non-deal) road shows, investor conferences and over 375 1-on-1 investor meetings.  In
addition, since 2020, the Company’s annual meetings have been conducted virtually through a
live webcast and online shareholder tools.  The Company believes the virtual meeting format
enables stockholders to participate fully, and equally, from any location around the world, at
little to no cost to them.  The format of the Company’s 2024 Annual Meeting has been designed
to ensure that its stockholders who attend the Company’s 2024 Annual Meeting will be
afforded the same rights and opportunities to participate as they would at an in-person
meeting.  For more information on the meeting format, see page 88.
The Board regularly assesses and refines the Company’s corporate governance policies
and procedures to take into account evolving best practices and the valuable feedback of the
Company’s shareholders and other stakeholders who have provided important external
viewpoints that inform the Company’s decisions and strategy.

By Mail. You may vote by proxy by filling out the vote instruction form and returning it in the envelope provided to you by your broker, bank, trustee, or other nominee.

At the Virtual Meeting. You may vote live at the virtual Annual Meeting at www.virtualshareholdermeeting.com/ERII2021 using your unique 16-digit control number which appears on the Notice Regarding the Availability of Proxy Materials, the proxy card (printed in the box and marked by the arrow), and the instructions that accompanied the proxy materials.

Q:

How does the Board of Directors recommend I vote on these proposals?

A:

The Board recommends a vote:

FOR the amendment of the Certificate of Incorporation to effect a phased declassification of the Board over the next three years;

FOR the election of director Olav Fjell;

FOR the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2021; and

FOR the approval of our executive compensation.

Q:

What is included in the proxy materials

A:

The proxy materials include this Proxy Statement and our Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the Securities and Exchange Commission (“SEC”) on March 12, 2021 (the “Annual Report”). These materials were first made available to you via the Internet on or about April 26, 2021. Our principal executive offices are located at 1717 Doolittle Drive, San Leandro, CA 94577, and our telephone number is (510) 483-7370. We maintain a website at www.energyrecovery.com. The information on our website is not a part of this Proxy Statement.

Q:

Why did I receive a Notice of Internet Availability of Proxy Materials instead of a full set of proxy materials?

A:

In accordance with the rules of the SEC, we have elected to furnish our proxy materials, including this Proxy Statement and the Annual Report, primarily via the Internet. The Notice containing instructions on how to access our proxy materials is first being mailed on or about April 26, 2021 to all stockholders entitled to vote at the virtual Annual Meeting. Stockholders may request to receive all future proxy materials in printed form by mail or electronically by e-mail by following the instructions contained in the Notice. We encourage stockholders to take advantage of the availability of our proxy materials via the Internet to help reduce the environmental impact of our Annual Meetings.

Q:

How many votes do I have?

A:

On each matter to be voted upon, you have one vote for each share of common stock you own as of the Record Date.

Q:

Can I change my vote or revoke my proxy after submitting my proxy?

A:

You may change your vote or revoke your proxy at any time prior to the taking of the vote at the Annual Meeting.

If you are the stockholder of record, you may change your vote by (1) granting a new proxy bearing a later date (which automatically revokes the earlier proxy) using any of the methods described on page 3 of this Proxy Statement (and until the applicable deadline for each method); (2) providing a written notice of revocation to the Company’s Secretary at Energy Recovery, Inc., 1717 Doolittle Drive, San Leandro, CA 94577 prior to your shares being voted; or (3) attending the Annual Meeting and voting at the Annual Meeting. Attendance at the Annual Meeting will not cause your previously granted proxy to be revoked unless you specifically so request or vote at the virtual Annual Meeting.

For shares you hold beneficially in street name, you generally may change your vote by submitting new voting instructions to your broker, bank, trustee, or nominee following the instructions they provided, or, if you have obtained a legal proxy from your broker, bank, trustee, or nominee giving you the right to vote your shares, by attending the virtual Annual Meeting and voting in person.

Q:

What if I return a proxy card but do not make specific choices?

A:

When proxies are properly dated, executed, and returned, the shares represented by such proxies will be voted at the Annual Meeting in accordance with the instructions of the stockholder. If no specific instructions are given, the shares will be voted in accordance with the recommendations of our Board of Directors as described on page 3 of this Proxy Statement. If any matters not described in this Proxy Statement are properly presented at the Annual Meeting, the proxy holders will use their own judgment to determine how to vote your shares. If the Annual Meeting is postponed or adjourned, the proxy holders can vote your shares on the new meeting date as well, unless you have revoked your proxy instructions, as described above under “Can I change my vote or revoke my proxy after submitting my proxy?”

Q:

Who pays for the expenses related to the preparation and mailing of the Proxy Statement?

A:

The Company will bear the costs of soliciting proxies, including the costs for the preparation, assembly, printing, and mailing of the Proxy Statement and related proxy materials. In addition, the Company will reimburse brokerage firms and other nominees representing beneficial owners of shares for their expenses in forwarding solicitation materials to beneficial owners of those shares. We have retained Alliance Advisors as our proxy solicitors, and proxies may be solicited by a representative of that firm. For its services, we will pay Alliance Advisors a fee of $9,500 plus reasonable expenses. Proxies may also be solicited by certain of the Company’s directors, officers, and regular employees, without additional compensation, either personally, by telephone, facsimile, or mail.

Q:

Who can vote at the Annual Meeting?

A:

Only stockholders of record at the close of business on April 12, 2020, the Record Date, will be entitled to notice of, and to vote at, our Annual Meeting. Each stockholder of record will be entitled to one vote on each matter for each share of common stock held on the Record Date. On the Record Date, the Company had 57,422,485 shares of common stock outstanding, held by 22 holders of record.

Q:

Will there be any other items of business on the agenda?

A:

We do not know of any business to be considered at the Annual Meeting other than the proposals described in this Proxy Statement; however, the proxy holders (who are the management representatives named on the proxy card) may vote using their discretion with respect to any other matters properly presented for a vote at the meeting.

Q:

How many votes are required for the approval of each item?

A:

Proposal No. 1 (declassification of board): An affirmative vote of a at least 66 2/3% of the voting power of the then outstanding shares of the Company, voting together as a single class is required to approve Proposal No. 1, provided that a quorum is present. The Board recommends a vote FOR Proposal No.1.

Proposal No. 2 (election of director): The candidate who receives the greatest number of votes cast at the Annual Meeting will be elected, provided that a quorum is present. The Board recommends a vote FOR the nominee.

Proposal No. 3 (ratification of Deloitte & Touche LLP as our independent registered public accountants) and Proposal No. 4 (advisory approval of the Company’s executive compensation): An affirmative vote of a majority of the shares of the Company’s common stock present and entitled to vote is required to approve Proposals No. 3 and No. 4, provided that a quorum is present. The Board recommends a vote FOR each of the Proposals No.3 and No.4.

Q:

What is the quorum requirement?

A:

A “quorum” of stockholders must be present for us to hold a valid meeting of stockholders. Stockholders representing a majority (more than 50%) of the voting power of our outstanding common stock as of the Record Date, present in person or represented by proxy, constitute a quorum for the transaction of business at the Annual Meeting.

Your shares will be counted towards the quorum only if you submit a valid proxy or if you vote in person at the meeting. Stockholders who submit signed and dated proxies without specifying their votes and broker “non-votes” described below will be counted towards the quorum requirement. If there is no quorum, the chairperson of the meeting or a majority of the votes present at the meeting may adjourn the meeting to another date.

Q:

What is a record holder?

A:

If your shares are registered directly in your name with our transfer agent, American Stock Transfer & Trust Company, LLC, you are considered a “record holder” of those shares. If you are a record holder, you will receive a Notice on how you may access and review the proxy materials on the Internet.

Q:

What is a beneficial owner?

A:

If your shares are held in a stock brokerage account, by a bank, or by another nominee, those shares are registered with American Stock Transfer & Trust Company, LLC in the “street name” of the brokerage account, bank, or other nominee, you are considered the “beneficial owner” of those shares. If you are a beneficial owner, your broker or other nominee will send you a form of voting instructions along with instructions on how to access proxy materials.

As a beneficial owner, you have the right to direct your broker, bank, or other nominee on how to vote your shares by using the voting instruction form included in the mailing or by following the instructions on the voting instruction card for voting via the Internet or telephone.

If there are multiple beneficial owners in the same household, your broker or other nominee may send only one set of voting instructions or copy of the proxy materials to your household. If you are receiving multiple copies of these materials and would like to receive a single copy in the future, please contact your broker, bank, or other nominee to request a single copy in the future.

Q:

How are votes counted?

A:

All shares of common stock represented by valid proxies will be voted in accordance with their instructions. In the absence of instructions, proxies will be voted “FOR” Proposals No. 1, 2, 3 and 4.

Brokers, banks, and other nominees may submit a proxy card for shares of common stock that they hold for a beneficial owner but may decline to vote on certain items because they have not received instructions from the beneficial owner. These are called “Broker Non-Votes” and are not included in the tabulation of the voting results for the election of directors or for purposes of determining the number of votes cast with respect to a particular proposal. Consequently, Broker Non‑Votes will not count as votes cast for purposes of Proposals No. 1, 2, 3 and 4.

Brokers have the discretion to vote such shares for which they have not received voting instructions from the beneficial owners on routine matters but not on non-routine matters. The only routine matter up for vote this year is the ratification of the independent registered public accounting firm (Proposal No. 3).

A broker is prohibited from voting on a non-routine matter unless the broker receives specific voting instructions from the beneficial owner of the shares. The declassification of the board (Proposal No. 1) election of directors (Proposal No. 2) and the advisory vote on executive compensation (Proposal No. 4) are non-routine matters, and your broker cannot vote your shares on these proposals unless you have timely returned applicable voting instructions to your broker.

Abstentions have no effect on the outcome of voting for Proposal No. 2, election of directors. Abstentions are treated as shares present or represented and voting regarding Proposals No. 1, No. 3 and No. 4, so abstentions have the same effect as negative votes on those proposals.

A summary of the voting provisions, provided a valid quorum is present or represented at the Annual Meeting, for the matters described in “What is the purpose of the Annual Meeting?” is as follows:

Accordingly, the nominee receiving the highest number of affirmative votes will be elected as a Class I director to serve (i) until the 2024 Annual Meeting of Stockholders, or (ii) our 2022 Annual Meeting of Stockholders if Proposal No. 1 is approved by our stockholders at the Annual Meeting (and in each case, until his respective successor is duly elected and qualified). Abstentions and broker non‑votes will have no effect on the outcome of the vote.

Q:

Who counts or tabulates the votes?

A:

The votes of stockholders attending the Annual Meeting and voting in person will be counted or tabulated by an independent inspector of election. For our meeting, a representative of Broadridge Investor Communications Solutions, Inc. will tabulate votes cast by proxy and in person.

Q:

How do I access the proxy materials and annual report via the Internet?

A:

A Notice will be mailed or emailed with instructions on how to access proxy materials via the Internet. This Proxy Statement, the 2020 Annual Report, and related proxy materials for the Annual Meeting of Stockholders to be held on June 10, 2021 will also be available electronically at http://ir.energyrecovery.com.

If you have previously chosen to receive the proxy materials via the Internet, you will be receiving an e-mail on or about April 26, 2021 with information on how to access stockholder information and instructions for voting over the Internet. Stockholders of record may vote via the Internet until 11:59 p.m. Eastern Daylight Time (8:59 p.m. Pacific Daylight Time) on June 9, 2021.

If your shares are registered in the name of a brokerage firm and you have not elected to receive proxy materials over the Internet, you may still be eligible to vote shares electronically over the Internet. Many brokerage firms participate in programs that provide eligible stockholders who receive a paper copy of the Proxy Statement and Annual Report the opportunity to vote via the Internet. If your brokerage firm participates in such a program, a form from the broker will provide voting instructions.

Stockholders can elect to view future Proxy Statements and Annual Reports over the Internet instead of receiving paper copies. Stockholders of record wishing to receive future stockholder materials electronically can elect this option by following the instructions provided when voting over the Internet at www.proxyvote.com.

Upon electing to view future Proxy Statements and Annual Reports over the Internet, you will receive an e-mail notification next year with instructions containing the Internet address of those materials. The choice to view future Proxy Statements and Annual Reports over the Internet will remain in effect until you contact your broker or the Company to rescind the instructions. Internet access does not have to be elected each year.

Stockholders who elected to receive this Proxy Statement electronically over the Internet and who would now like to receive a paper copy of this Proxy Statement so that they may submit a paper proxy in lieu of an electronic proxy should contact either their broker or the Company.

Q:

What should I do if I get more than one proxy or voting instruction card?

A:

Stockholders may receive more than one set of voting materials, including multiple copies of the proxy materials and multiple Notices, proxy cards, or voting instruction cards. For example, stockholders who hold shares in more than one brokerage account may receive separate sets of proxy materials for each brokerage account in which shares are held. Stockholders of record whose shares are registered in more than one name will receive more than one set of proxy materials or one Notice. You should vote in accordance with all of the proxy cards and voting instruction cards you receive relating to our Annual Meeting to ensure that all of your shares are counted.

Q:

I share an address with another stockholder, and we received only one paper copy of the proxy materials. How may I obtain an additional copy of the proxy materials?

A:

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Proxy Statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single Proxy Statement addressed to those stockholders. This process is commonly referred to as “house-holding.”

Brokers with account holders who are Energy Recovery stockholders may be house-holding our proxy materials. A single set of proxy materials may be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that it will be house-holding communications to your address, house-holding will continue until you are notified otherwise or until you notify your broker or The Company that you no longer wish to participate in house-holding.

If, at any time, you no longer wish to participate in house-holding and would prefer to receive a separate Proxy Statement and Annual Report, you may (1) notify your broker, (2) direct your written request to: Investor Relations, Energy Recovery, Inc., 1717 Doolittle Drive, San Leandro, CA 94577 or (3) contact our Investor Relations department by email at IR@energyrecover.com or by telephone at (281) 962-8105. Stockholders who receive multiple copies of the Proxy Statement or Annual Report at their address and would like to request house-holding of their communications should contact their broker. In addition, we will promptly deliver, upon written or oral request to the address or telephone number above, a separate copy of the Annual Report and Proxy Statement to a stockholder at a shared address to which a single copy of the documents was delivered.

Q:

What if I have questions about my Energy Recovery shares or need to change my mailing address?

A:

You may contact our transfer agent, American Stock Transfer & Trust Company, LLC, by telephone at (800) 937-5449 (U.S.) or (718) 921-8124 (outside the U.S.), or by email at info@amstock.com, if you have questions about your Energy Recovery shares or need to change your mailing address.

Q:

Where can I find the voting results of the Annual Meeting?

A:

We will announce preliminary voting results at the Annual Meeting. We will also disclose voting results on a Current Report on Form 8-K that we will file with the SEC within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Current Report on Form 8‑K within four business days after the Annual Meeting, we will file a Current Report on Form 8‑K to publish preliminary results and will provide the final results in an amendment to this Current Report on Form 8-K as soon as they become available.

PROPOSALS TO BE VOTED ON AT THE MEETING

Proposal No.1: Amendment of Certificate of Incorporation to Effect a Declassification ofdirectors constituting the Board of Directors

Currently, the Company’s Certificate of Incorporation provides for a classified Board divided into three classes of directors, with each class elected for a three-year term. The classification of the Board results in staggered elections, with each class of directors standing for election every third year. One class consists of two members whose terms expire upon the election and qualification of their successorsis currently set at the Annual Meeting (“ClassI”), one class consists of three members whose terms expire at the 2022 Annual Meeting of Stockholders (“ClassII”), and one class consists of two members whose terms expire at the 2023 Annual Meeting of Stockholders (“ClassIII”).

After careful consideration, the Board has determined that it is advisable and in the best interests of the Company and its stockholders to amend our Certificate of Incorporation to declassify the Board to allow the Company’s stockholders to vote on the election of the entire Board on an annual basis, rather than on a staggered basis.

The general description of the proposed amendments to our Certificate of Incorporation set forth in this Proposal No. 1 is qualified in its entirety by reference to the text thereof, which is attached as Appendix A to this proxy statement.

Declassification of the Board

If this Proposal No. 1 is approved by the Company’s stockholders at the Annual Meeting, the declassification of the Board will be phased in over a three-year period as follows:

at the Annual Meeting of stockholders, the Class I director will be elected to hold office for a term of one year;

at the 2022 Annual Meeting of Stockholders, each of the Class I directors and the Class II directors will be elected to hold office for a term of one year; and

at the 2023 Annual Meeting of Stockholders, and at each annual meeting of stockholders thereafter, all directors will stand for election for one-year terms.

seven

Under the proposed amendments, the annual election of directors will be phased in gradually to assure a smooth transition. The proposed amendments will not shorten the term of a current director. If this Proposal No. 1 is approved by the requisite vote of the Company’s stockholders, any director elected to fill a vacancy that did not arise from an increase in the size of the Board will hold office for the term that remains for the applicable vacating director, and any director elected to fill a vacancy that resulted from an increase in the size of the Board will be elected to serve until the next annual meeting of stockholders.

If this Proposal No. 1directors.  Mr. Robert Yu Lang Mao is not approved by the requisite vote of the Company’s stockholders, the Board will remain classified, with each class of directors serving a term expiring at the annual meeting of stockholders held in the third year following the year of their election.

If this Proposal No. 1 is passed by the requisite vote of the Company’s stockholders, it will become effective when the Company files the amendment to the Certificate of Incorporation with the Secretary of State of the State of Delaware, which the Company intends to do promptly following the 2021 Annual Meeting.

Considerations of the Board

The Company has historically had a classified board structure in which directors have been divided into three classes and one class is elected each year to serve a three-year term. The Board has historically believed that this classified board structure promotes continuity and stability of strategy, ensures that a potential acquirer in a takeover situation negotiates with the Board, and facilitates the ability of the Board to focus on creating long-term stockholder value. The Board also is aware that the current trend in corporate governance is leading away from classified boards in favor of electing all directors annually and also recognizes that a classified board structure may reduce directors’ accountability to stockholders because such a structure does not enable stockholders to express a view on each director’s performance by means of an annual vote. Moreover, many institutional investors believe that the election of directors is the primary means for stockholders to influence corporate governance policies and to hold management accountable for implementing those policies.

In determining whether to support declassification of the Board, the Board carefully considered these factors and has determined that it is advisable and in the best interests of the Company and its stockholders to declassify the Board.

Vote Required

The affirmative vote of at least 66 2/3% of the voting power of the then outstanding shares of our stock that are present in person or by proxy and entitled to vote at the Annual Meeting.

THE BOARD RECOMMENDS THAT THE STOCKHOLDERS VOTEFORTHE ADOPTION OF THE PROPOSED AMENDMENTS TO OUR CERTIFICATE OF INCORPORATION TO PROVIDE FOR THE ANNUAL ELECTION OF DIRECTORS.

The management proxy holders will vote all duly submitted Proxies FOR the adoption of the proposed amendments to our Certificate of Incorporation unless duly instructed otherwise.

Proposal No.2: Election of Director

The Company’s Nominating and Governance Committee has nominated, and our Board has designated, Mr. Olav Fjell to stand for election as a Class I director at the Annual Meeting.

Board Leadership and Governance Structure

ERI is committed to maintaining superior governance practices, and we regularly assess and refine our corporate governance policies and procedures to take into account evolving best practices.

The Board is responsible for establishing and maintaining the most effective leadership structure for the Company. Historically,In October 2023, the Board has determined thatelected Ms. Tondreau as the roles of the ChairmanChair of the Board and appointed

Mr. Moon as the Chief Executive Officer should be separate, withPresident and CEO.  The Company believes that this separation of roles and
allocation of distinct responsibilities to each role facilitates communication between the Chairman an independent director, because that structure affords independent
Company’s senior management and the full Board leadershipabout issues such as corporate governance,
management development, succession planning, executive compensation, and allows the Chief Executive OfficerCompany’s
performance, and best facilitates permitting the Company’s President and CEO to concentrate
on the Company’s business.  Nevertheless,Pursuant to the Company’s corporate governance guidelines, the
Board believes it is appropriate to retainmay in the discretion and flexibility to changefuture combine the structure from time to time as needed to provide appropriate leadership forrole of the Company given the specific circumstances then facing the Company.

The Board is currently led by Mr. Robert Mao, our Chairman,Company’s President and Chief Executive Officer, and Ms. Pamela Tondreau, our Lead Independent Director. The Company believes that our current structure is appropriate at this time as it strikes a balance between effective and efficient Company leadership and oversight by the independent directors.

The Board believes that having Mr. Mao serve as both Chairman and Chief Executive Officer is the most effective leadership structure for the Company at this time. Energy Recovery is at an inflection point in its development as it transitions from a company focused on a single industry since its inception, desalination, to one focused on leveraging its unique IP to develop its PX technology into a more diverse set of industries. In addition, the Company is focused on rapid growth, evolving from a small niche company, to larger more diversified one which demands a new look at operations to assure success. Mr. Mao has over 30 years of experience in the technology and telecommunications industry worldwide, with extensive experience in incubating new and developing technologies, and prior service as a director of other large public companies. This experience makes him uniquely well positioned to lead the Company’s business, operations and strategy during this transition.

The combination of the Chief Executive Officer and Chairman roles allows consistent communication and alignment throughout the Company, assuring effective and efficient implementation of corporate strategy and is important in unifying our team members, including the members of the Board, behind a single vision. The combination of the Chief Executive Officer and Chairman roles is balanced by our strong Lead Independent Director position, by the independence of all our other directors, each of whom has significant business experience and by the three principal committees of the Board, each of which consists solely of independent directors.

The Lead Independent Director is an important element of ensuring strong independent Board leadership. We believe the Lead Independent Director provides the CompanyCEO and the Board with Chair of

the same independent leadership, oversight and benefitsBoard.  If that would be provided by an independent chairman. Our Lead Independent Director is chosen bywere to happen, then the independent Directors. In May 2020, Ms. Pamela Tondreau was elected the Lead Independent Director, succeeding Mr. Arve Hanstveit. Ms. Tondreau has been a member of the Board since 2019 and she currently serves as the Chairman of the Compensation Committee and a member of the Nominating and Corporate Governance Committee. Ms. Tondreau’s extensive corporate and legal experience make her qualified to serve as Lead Independent Director of our Board.

The Lead Independent Director’s duties include consulting with our Chairman and Chief Executive Officer and presiding over meetings of the Board at which the Chairman is not present, including executive sessions of the Board and the independent directors. The Lead Independent Director’s duties also include facilitating discussions amongBoard’s independent directors on key issues and concerns outside of Board meetings, serving aswould elect a liaison between the Chairman and the other directors, reviewing information to be sent to the Board, collaborating with the Chairman and other members of Company management to set meeting agendas and Board information, assisting the chairs of the committees of the Board as requested, and performing such other functions and responsibilities as requested by the Board or the independent directors from time to time. In performing the duties described above, the Lead

Independent Director is expected to consult with, and does consult with, the chairs of the appropriate Board committees.

Director Independence

The Nominating and Corporate Governance Committee and the Board undertake an
annual review of director independence.  The Nominating and Corporate Governance
Committee and the Board evaluated all business and charitable relationships between the
Company and the Company’s non-employee directors, and all other relevant facts and
circumstances.  Based on information provided by each director concerning his background,
employment and affiliations, including family relationships, ourthe Board of Directors has affirmatively
determined that, except for Mr. MaoMoon who is currently serving as an employee,the Company’s President and
CEO, and Mr. Mao who previously served as the Company’s President and CEO, none of ourthe
current directors or continuing director nominees have a relationship that would interfere with
the exercise of independent judgment in carrying out the responsibilities of a director and that
each of these directors is “independent” as that term is defined under the applicable rules and
regulations of the SEC and the listing standards of The Nasdaq Stock MarketNASDAQ (the “Applicable Rules”Applicable Rules).  In making
these determinations, ourthe Board of Directors considered the current and prior relationships that each
director has with ourthe Company and all other facts and circumstances ourthe Board of Directors deemed
relevant in determining their independence.

non-employee director, as defined pursuant to Rule 16b-3 promulgated under the Exchange
Act, and an outside director, as defined pursuant to Section 162(m) of the Internal Revenue Code (“IRC”)
Section 162(m), as amended.

The Board’s standards for determining director independence meet or exceed the applicable rules

While the Nominating and Corporate Governance Committee does not have a written
policy regarding diversity in identifying nominees for directors, the committeeNominating and Corporate
Governance Committee takes diversity into account when looking for best available candidates
to serve on the Board.  In the past, when new directors have been added to ourthe Board, the
Board or Nominating and Corporate Governance Committee has endeavored to select director
candidates who have business, scientific or regulatory specializations; technical skills; or other
backgrounds that increased the range of experience and diversity of perspectives within our the
Board in ways that pertain to ourthe Company’s current and future business goals.  The
Nominating and Corporate Governance Committee also considers diversity in terms of gender,
ethnic background, and national origin.

There are no differences in the manner in which the Nominating and Corporate
Governance Committee evaluates nominees for director based on whether the nominee is
recommended by a stockholder or by the Nominating and Corporate Governance Committee
itself.

In reviewing potential candidates for the Board, the Nominating and Corporate
Governance Committee considers numerous factors including:

whether or not the person has any
relationships that might impair his
or her independence, such as any
business, financial, or family
relationships with the Company, the
Company’s management, the
Company’s stockholders, or the
Company’s affiliates;
whether or not the person serves on
boards of, or is otherwise affiliated
with, competing companies;
whether or not the person is willing
to serve as, and willing and able to
commit the time necessary for the
performance of the duties of, a
director of the Company; and
the contribution that the person can
make to the Board and the
Company, with consideration given
to the person’s experience in the
fields of energy, technology, and
manufacturing as well as leadership
or entrepreneurial experience in
business or education.

whether or not the person has any relationships that might impair his or her independence, such as any business, financial, or family relationships with the Company, its management, its stockholders, or their affiliates;

whether or not the person serves on boards of, or is otherwise affiliated with, competing companies;

whether or not the person is willing to serve as, and willing and able to commit the time necessary for the performance of the duties of, a director of the Company; and

the contribution that the person can make to the Board and the Company, with consideration given to the person’s experience in the fields of energy, technology, and manufacturing as well as leadership or entrepreneurial experience in business or education.

Energy Recovery, Inc.2024 Proxy Statement | 28
Of greatest importance is the individual’s integrity and ability to bring to the Company experience and
knowledge in areas related to the Company’s current and future business.  The Board intends to
continue using these criteria to evaluate candidates for election to the Board.

Board Role in Risk Management

The goal of the Company’s risk management process is to understand and manage
material risks impacting ourthe Company’s business.  ManagementThe Company’s management is responsible
for identifying and managing the risks, while the Company’s directors provide oversight to the
Company’s management in this process, which is designed to support the achievement of
organizational objectives, including strategic objectives, to improve long-term organizational
performance to enhance stockholder value.  A fundamental part of risk management is not only
understanding the risks we facethe Company faces and what steps the Company’s management is
taking to manage those risks, but also understanding what level of risk is appropriate.  ManagementThe
Company’s management is responsible for establishing ourthe Company’s business strategy,

Compensation Philosophy and Objectives

The primary objective of ourthe Company’s executive compensation program is to attract,
retain, and motivate the talent we needit needs to meet and/or exceed the Company’s strategic,
operational and financial goals ofgoals.  Additionally, the Company. Additionally, we wantCompany wants to reward superior
performance and align the long-term interests of ourits executives with our the Company’s
stockholders.  The guiding principles of ourthe Company’s compensation program involve:

incentivizing our key executives to exceed strategic, operational, and financial goals;

attracting and retaining mission critical executive talent;

aligning outcomes and rewards with stockholder expectations; and

rewarding superior performance.

incentivizing the Company’s key
executives to exceed strategic,
operational and financial goals;
attracting and retaining mission
critical executive talent;
aligning outcomes and rewards
with stockholder expectations; and
rewarding superior performance.
The Compensation Committee annually reviews the Company’s executive compensation
program to ensure an appropriate alignment between ourthe Company’s compensation policies
and programs and ourthe Company’s business needs and the interests of our the Company’s
stockholders.  OurThe Company’s executive compensation programs are reviewed to ensure they
achieve a balance between rewarding performance and retaining key people while
accommodating a continuing effort to manage the Company’sits share utilization rate to minimize the dilutive
effects of equity awards to the Company’s stockholders.

In addition, the Compensation Committee reviews ourthe Company’s compensation policies

and practices to determine areas of resulting risk and the actions that we havethe Company has taken,
or should take, to mitigate any such identified risk.  Based on the Compensation Committee’s
review of ourthe Company’s compensation policies and practices with inputs from its independent
compensation consultant, we dothe Company does not believe that any risks relating from ourthe
Company’s compensation policies and practices for ourits employees are reasonably likely to have
a material adverse effect on ourthe Company’s business.

A significant part of ourthe Company’s executive compensation philosophy policy is designed to link
executive compensation to ourthe Company’s performance through at-risk compensation
opportunities, providing significant reward to executives based on ourthe Company’s success.  As
such, the Compensation Committee believes that ourthe Company’s executive officers���officers’ total
compensation should be reflective of ourthe Company’s short and long-term performance.
Accordingly, a significant amount of ourthe Company’s executive officers’ compensation is
composed of performance-based bonus opportunities and equity awards, which derive their
value based on both stock-based performance and Companythe Company’s financial and operational
performance.  As a result, a significant majority of ourthe Company’s executive officers’ target total
direct compensation opportunity is “at risk.”  There is no assurance that the target annual
bonus opportunities or grant date fair values reported for these equity awards will be reflective
of their actual economic value or that comparable amounts will ever be realized by the
Company’s executive officers.

Additionally, in 2020,2023, the CompanyCompany’s granted to its named executive officers a combination of stock options and restricted stock units (“NEOs RSUs.  RSUs”).

meaningful and durable retention tool even in periods of volatile stock price performance with

Executive Compensation Process

The Compensation Committee is responsible for establishing and implementing executive
compensation policies and programs in a manner consistent with ourthe Company’s compensation
objectives and principles.

Compensation Committee and Board of Directors.Directors
Historically, the Compensation Committee has determined annual compensation and
granted annual equity awards at one or more meetings held during the first quarter of the year. However,
In addition, at various meetings throughout the year, the Compensation Committee also
considers matters related to individual compensation, such as compensation for new executive
hires, as well as high-level strategic issues, such as the efficacy of the Company’s compensation
strategy, potential modifications to that strategy and new market and regulatory trends, plans
or approaches to compensation in the Company’s industries.

industries the Company participate.

Role of Executive Officers. Officers
The Compensation Committee meets regularly in executive meetings.  Our Chief Executive OfficerThe Company’s
President and Vice President of Human Resources, along with legal counsel as appropriate,CEO and CFO work together to design and develop compensation programs for our
the Compensation Committee’s consideration, and ultimate approval, recommend changes to
existing compensation programs, recommend performance targets to be achieved under those
programs and implement the decisions of the Compensation Committee.  These individuals also
provide information to ourthe Company’s independent compensation consultant so that it can
perform its duties for the Compensation Committee.

Energy Recovery, Inc.2024 Proxy Statement | 48
At the beginning of each year, our Chief Executive Officerthe Company’s President and CEO provides
recommendations to the Compensation Committee on the compensation levels of named executive officers other than his own,the
Company’s Other NEOs, as well as his review of each other named executive officer’sOther NEO’s performance and
contributions during the previous year.  The Company’s President and CEO does not make any
recommendations to the Compensation Committee with respect to his compensation levels.
When appropriate, members of ourthe Company’s management team, including our Chief Executive Officerthe Company’s
President and Vice President of Human Resources,CEO and CFO, attend portions of the Compensation Committee meetings to
provide information and answer questions.  No named executive officerNEO voted in the final determinations regarding
the structure or amount of any component of histheir compensation package.

Our

The Compensation Committee is responsible for making final decisions on compensation
for ourthe Company’s executive officers.  For all executive officers, as part of its deliberations, the
Compensation Committee may review and consider, as appropriate, one or more of the
following: (i) analysis of the Company’s historical Company executive compensation levels and current
company-wide compensation levels, (ii) trends in compensation paid to similarly situated
executives at ourthe Company’s peer companies developed by a compensation consultant, (iii) an
executive officer’s tenure, past performance and expected contribution to future results,
(iv) criticality of the executive position (both on an absolute basis and relative to other roles
within the organization), and (v) our Chief Executive Officer’sthe Company’s President and CEO’s recommendations based
on his direct knowledge of each executive officer’s performance and contributions during the
previous year as well as expected contributions in the coming year.

The Compensation Committee has not established any formal policies or guidelines for
allocating compensation between current and long-term incentive compensation, or between
cash and non-cash compensation.  The Compensation Committee considers relevant market
data, such as the compensation practices of ourthe Company’s peer group discussed below under “Competitive Positioning”,
“Competitive Positioning,” as well as key qualitative factors when determining each executive’s
recommended pay level.  In general, however, the Compensation Committee emphasizes
equity compensation over cash compensation to promote long-term thinking, strategy and
growth.  In determining the amount and mix of compensation elements and whether each
element provides the correct incentives and rewards for performance consistent with ourthe
Company’s short and long-term goals and objectives, the Compensation Committee relies on its
judgment about each individual rather than adopting a formulaic approach to compensatory
decisions.

The Compensation Committee has the authority under its charter to engage the services
of outside advisors, experts and others to assist it.  Accordingly, the Compensation Committee
retained Compensia a national compensation consulting firm, to advise on matters related to the compensation of its executive officers,
including the Chief Executive Officer.Company’s President and CEO, and the Board.  For 2020,2023, Compensia advised the
Compensation Committee on best practices to attract, retain and incentivize our the Company’s
executives, assisted in the design of ourthe Company’s compensation plan, and derived the peer
group and resulting compensation benchmark data against which the Company’s overall
compensation structure and levels are compared.

the listing standards of the Nasdaq Stock Market,NASDAQ, the Compensation Committee has determined that its
relationship with Compensia and the work of Compensia on behalf of the Compensation
Committee hashave not raised any conflict of interest.

competitive market compensation data and directed Compensia to develop a peer group of
companies against which Energy Recovery’sthe Company’s overall compensation may be compared.  While we havethe

Base Salaries of Named Executive Officers

Base salaries are designed to provide ourthe Company’s executives with a stable source of
income commensurate with their responsibility, experience and performance.  The
Compensation Committee begins with an analysis of base pay relative to the market and ourthe
Company’s peer group.  The Compensation Committee makes adjustments based on vertical
variables such as pay parity relative to other executive officers, experience and internal
accountability and does not target any particular percentile or pay ranking.  The Compensation
Committee reviews base salaries annually and solicits input from the Chief Executive OfficerCompany’s President and
CEO for non-CEO base salaries.  The President and CEO does not provide any input or
recommendations with respect to his own base salary.  The following table describes the
changes that were made to the base salary of the named executive officers based on review of
the factors noted above.  Mr. Clemente received a 14% increase to his base salary in connection with his promotion to Senior Vice President, Water. The other Named Executive Officers’Company’s NEOs’ base salaries were increased on average by 2.5%

Annual Cash Incentive Compensation

The Company’s Annual Incentive Plan or (“AIP”), is our annuala cash incentive plan and is designed to
encourage the performance and retention of eligible employees in recognition of individual
achievement that contributes to the Company’s strategic and financial successsuccess.
Energy Recovery, Inc.2024 Proxy Statement | 52
The AIP is intended to incentivize short-term performance consistent with Company the Company’s
strategy and the achievement of key financial metrics.  Payments under the AIP to a participantthe
Company’s NEOs are based on a formula that takes into account both the level of achievement
of Companythe Company’s performance goals for the year and the level of achievement of individual
performance objectives.  The AIP includes the following performance characteristics:

At the onset of each year, the Compensation Committee establishes the total annual bonus pool (the “Bonus Pool”), the profitability target or other financial metrics applicable to that year (the “Performance Target”) and the minimum performance threshold;

If the Company’s performance equals or exceeds the Performance Target, the Bonus Pool is funded at 100%;

If the Company’s performance exceeds the minimum performance threshold but is less than the Performance Target, the Bonus Pool is calculated based on the allocation curve set forth in the AIP;

If the Company’s performance is less than the minimum performance threshold, the Bonus Pool is not funded; however, the Compensation Committee, in its sole discretion, may elect to approve some funding for the Bonus Pool to be awarded to individual participants for extraordinary performance as determined by the AIP plan committee and approved by the Compensation Committee;

Payments to participants in the AIP if individual performance objectives established under the AIP are met is based on a percentage of base salary; and

The AIP limits the Bonus Pool and individual targets to 100% of target.

For 2020, the Compensation Committee elected to embed the Performance Target directly into the individual MBOs of the Chief Executive Officer and other plan participants in place of the funding mechanism described above. This was due, in large part, to the large number of variables in the Company’s 2020 projected budget. Accordingly, in 2020, a Participant’s2023, each NEO’s bonus determination under the PlanAIP was

determined by multiplying such participant’s base salary by their AIP target bybased on the percentage of achievement of his/her individual MBOs. The Performance Target in 2020 was met 100% by the Company.

grant additional performance-based awards granted to its executive officers should belater in the form year once those award terms were
finalized.  In July 2023, the Compensation Committee determined to postpone the development
of option awards. this performance-based equity program and issued an additional grant of RSUs to NEOs to
constitute the full intended annual award for each individual.  In 2020, 100%addition, in October 2023, the
Compensation Committee approved additional RSUs to Messrs. Clemente and Ghasripoor as

related to thehis appointment as Interim President and Chief Executive Officer and Chief Financial Officer and 50% of the awards to our other named executive officers were in the form of option awards. The Company believes that option awards align the interests of our executives to our common stockholders since stock price appreciation is necessary for our executives to derive financial benefit from the option awards. Accordingly, the Company believes that our use of option awards properly incentivize our executives to focus on the long-term performance of the Company, and as such, are performance-based in nature.

The vesting schedule for the option awards provides that 25% of the options vest on the one-year anniversary of the vesting commencement date, and thereafter, 1/36th of the remaining options vest at the end of each month of active service. Officer.

Change in Control Severance Plan

In August 2009, the Company’s Board of Directors adopted a Change in Control Severance Plan for key employees. In March 2012, the Board adopted a revised

The Energy Recovery, Inc. Change in Control Severance Plan (the “CIC Plan”) for highly paid employees. On December 31, 2012,is
summarized below under the caption “Change in Control Plan” and on each anniversary thereafter,the potential payments are
summarized below under the caption “Potential Payments under the Change in Control Plan.”
Designed as a retention tool, the CIC Plan will beprotects participating executives from economic
harm in the event that their employment is actually or constructively terminated after a change
in control of the Company.  Under this “double trigger” approach, participating executives are
eligible for severance and other benefits under the CIC Plan if they are terminated without
“Cause” or leave for “Good Reason,” as those terms are defined below, within 18 months after
a change in control of the Company.
The Company believes these change of control severance benefits are an essential
element of its executive compensation program and assist the Company in recruiting and
retaining talented individuals.  By establishing these change in control severance benefits, the
Company believes it can mitigate the distraction and loss of executive officers that may occur in
connection with a rumored or actual change in control and protect stockholder interests while a
transaction is under consideration or pending.
Energy Recovery, Inc.2024 Proxy Statement | 57
Change in Control Plan
Pursuant to the terms of the CIC Plan, on each December 31, the CIC Plan is extended
automatically for an additional year unless the Compensation Committee of the Board of Directors delivers written
notice, at least six months prior to the end of each such term, to each participant that the CIC Plan will not be extended. Accordingly, the CIC Plan was extended through December 31, 2021. Each of the named executive officers (except for Mr. Mao) currently serving participates in the CIC Plan described below.

The CIC Plan is summarized below under the caption “Potential Payments Upon Termination or Change of Control” following the compensation tables. Designed as a retention tool, the CIC Plan protects participating executives from economic harm in the event that their employment is actually or constructively terminated after a change in control of the Company. Under this “double trigger” approach, participating executives are eligible for severance and other benefits under the CIC Plan if they are terminated without “Cause” or leave for “Good Reason,” as those terms are defined below, within 18 months after a change in control of the Company.

We believe these change of control severance benefits are an essential element of our executive compensation program and assist us in recruiting and retaining talented individuals. By establishing these change in control severance benefits, we believe we can mitigate the distraction and loss of executive officers that may occur in connection with a rumored or actual change in control and protect stockholder interests while a transaction is under consideration or pending.

Severance and Termination Compensation

In February 2021, the Company’s Board of Directors approved, adopted and established the Energy Recovery, Inc. Severance Plan for the benefit of certain key members of management and other senior employees (the “Severance Plan”), including each of the Named Executive Officers. The Severance Plan sets forth severance benefits in the event of a Qualifying Termination (as defined in the Severance Plan), which includes (i) all payments required by applicable law, including all earned and unpaid salary, all earned but unpaid and un-deferred bonus attributable to the year that ends immediately before the year in which the termination occurs, and other benefits under applicable benefit plans to which the employee was entitled upon such termination; (ii) six (6) months’ salary based on the employee’s annual base salary in effect on the effective date of their termination; (iii) to the extent the Eligible Employee (as defined in the Severance Plan) is eligible and timely elects to continue coverage under the Employer’s health or other benefits plans pursuant to COBRA, payment of Employer’s portion of any such health or other benefit plans premiums on behalf of the Eligible Employee (at the employer level in effect immediately prior to the effective date of termination) towards the Eligible Employee’s COBRA premiums until the earlier of (A) six (6) months following the effective date of termination, or (B) the date the Eligible Employee becomes eligible for coverage under a subsequent employer health plan, whether the Eligible Employee enrolls in such coverage or not, and whether or not the benefit levels and costs are comparable; and (iv) immediate vesting of twenty-five percent (25%) of all unvested equity compensation held by the Eligible Employee on the effective date of termination (the “Accelerated Equity”) which Accelerated Equity, notwithstanding anything to the contrary, may be exercised, where applicable, for up to six (6) months after the effective date of termination; in the case of unvested equity compensation where the amount payable is based on the satisfaction of performance criteria, the amount of unvested equity will be determined by deeming all performance criteria satisfied at 100% target; to the extent the equity compensation is subject to Code Section 409A, the vesting acceleration of the equity compensation shall not cause any distribution or payment under the equity compensation to be made before the earliest date it may be made without violating Code Section 409A. The severance benefits are contingent upon the employee meeting certain eligibility requirements, including delivering to the Company a general release. Because it may be difficult for our executive officers to find comparable employment following a termination without cause, these severance benefits are intended to ease the consequences to an executive officer of an unexpected termination of employment. We also believe that having such arrangements in place can help us attract and retain key employees in a marketplace where these types of arrangements are commonly offered by our peer companies.

Compensation Policies and Practices as They Relate to Risk Management

Our Compensation Committee has reviewed our compensation programs for our employees and believes that our compensation programs are structured in a manner that does not create risks that are reasonably likely to have a material adverse effect on the Company. The Compensation Committee considered, among other factors, the allocation of compensation among annual base salary, AIP and long-term equity awards.

Report of the Compensation Committee

This report is not deemed to be soliciting material filed with the SEC or subject to the liabilities of Section 18 of the Exchange Act, except to the extent that the Company specifically incorporates it by reference into a document filed with the SEC.

The Compensation Committee reviewed and discussed the Compensation Discussion and Analysis (“CD&A”) set forth above with the Company’s management. Based on the review and discussions, the Compensation Committee recommended to the Company’s Board of Directors that the CD&A be included in this Proxy Statement.

Potential Payments Upon Termination or Change of Control

Change in Control Plan

We adopted the CIC Plan in March 2012 to provide change in control severance benefits for certain designated key employees. Each of the named executive officers currently serving participates in the CIC Plan described below.

The CIC Plan became effective on March 5, 2012. On December 31, and on each anniversary thereafter, the CIC Plan is extended automatically for an additional year unless the Compensation Committee of the Company’s Board of Directors delivers written notice, at least six months prior to the end of each such term, to each participant that the CIC Plan will not be extended.  As a result, on December 31, 2020,2023, the CIC Plan was

automatically extended through December 31, 2021.

2024.

The Compensation Committee is authorized by the CIC Plan to designate any full-time
employee of the Company as a participant.  The participants include the Company’s executive
officers and other designated key employees.

A participant is entitled to severance benefits under the CIC Plan if a change of control
occurs and the acquiring company terminates the participant’s employment without cause, or
the participant terminates his or her employment with good reason, in either case within
18 months after a change in control (including, but not limited to, an acquisition of a controlling
interest in the Company by a third party).  The CIC Plan sets forth definitions of cause, good
reason and change in control, which are described in full at the end of this summary.

The severance benefits, conditioned on the participant’s signing a release in favor of the
Company and complying with certain other covenants under the CIC Plan, include the following (in
(in addition to then earned and unpaid amounts owed less deductions required or permitted by
law):

Cash Compensation

A lump-sum payment equal to (i)

Additional 12 months of regular base pay plus (ii) salary upon termination
100% of the participant’s target annual bonus forin the fiscal year in whichof the
occurrence of the change inof control occurs;

COBRA Benefits

Company paid coverage following first eligibility limited to the
lower of 12 months or re-employment eligibility of a comparable
plan with another employer

Equity Compensation
Immediate vesting of all100% of unvested equity compensation held by the participant asawards upon
termination
Other Compensation
Maximum of the date$10,000 of termination (and for this purpose, all performance criteria, if any, underlying unvested awards are deemed to be satisfied at 100% of target) (as described further below);

reasonable outplacement costs

The Company’s regular payment of the monthly premium under COBRA, if the participant timely elects to continue medical, dental, and vision benefits under COBRA, for up to 12 months after employment termination (but not continuing after the participant becomes eligible for these benefits with another employer); and

Payment by the Company of up to $10,000 for reasonable costs of outplacement services.

32

The CIC Plan also provides that if a change in control occurs and a participant’s equity

compensation is not converted, assumed or replaced by a successor entity with an equivalent
award, then immediately prior to the change in control, the participant’s equity compensation
shall become fully exercisable and vested and all forfeiture restrictions on such equity
compensation shall immediately lapse.  In the case of equity compensation, the amount of
which is based on the satisfaction of performance criteria, all performance criteria will be
deemed satisfied at target.  The conversion, assumption or replacement of an equity award for
another equity award of stock that is not publicly traded shall not be considered an equivalent
award for purposes of the CIC Plan.

Energy Recovery, Inc.2024 Proxy Statement | 58
In no event is the Company obligated to gross up any payment or benefit to a participant
to avoid the effects of the “parachute rules” of IRC Sections 280G and 4999 of the Code.4999.  Benefits to a
participant, however, may be reduced if the reduction would result in the participant receiving
a greater payment on an after-tax basis due to the application of those sections of the tax law (such
(such provision, a “better after-tax” provision).  Additionally, payments may be conditioned or
delayed as needed to be exempt from or comply with IRC Section 409A of the Code relating to “nonqualified“non-
qualified deferred compensation.”

The CIC Plan also obligates the Company to make all payments to a Participant required by
applicable law upon employment termination such as earned but unpaid salary and bonus (without
(without regard to a release or other covenants of the participant in the CIC Plan and subject to
deductions required or permitted by applicable law).

Severance and Termination Plan
The Energy Recovery, Inc. Severance Plan (the “Severance Plan”) was approved and
adopted by the Board in February 2021 for the benefit of certain key members of management
and other senior employees, including each of the NEOs.
Designed as a retention tool, the Severance Plan is designed to protect participating
executives from economic harm in the event of a Qualifying Termination (as defined in the
Severance Plan).  The Company believes these severance benefits are an essential element of
its executive compensation program and assist the Company in recruiting and retaining
talented individuals.  The Severance Plan is summarized below under the caption “Severance
Benefits” and the potential payments are summarized below under the caption “Potential
Payments under the Severance Plan.”
Severance Benefits
The Severance Plan sets forth severance benefits in the event of a Qualifying Termination,
which includes all payments required by applicable law, including all earned and unpaid salary,
all earned but unpaid and undeferred bonus attributable to the year that ends immediately
before the year in which the termination occurs and other benefits under applicable benefit
plans to which the employee was entitled upon such termination.  In addition, the Severance
Plan includes the following benefits.
Cash Compensation

These amounts consist

Additional 6 months of twelve months’ base pay and 100% of the target annual bonus. The 2020 annual base salary for Mr. Mao represents the number of months of serviceupon termination
COBRA Benefits
Company paid coverage following first eligibility limited to the Company during the year beginning in January 1, 2020 through May 4, 2020 (4 months) at an annualized base salary
lower of $450,000 and from May 5, 2020 at an annualized base salary6 months or re-employment eligibility of $500,000.

Extension of post-termination exercise period of vested stock
options from 3 months to a Change in Control (whether or not the participant’s employment is terminated) if a Change of Control occurs and (i) the Company’s shares are no longer publicly traded or (ii) if a publicly-traded company acquires the Company, but does not replace unvested Company awards with defined equivalent equity compensation applicable to the acquiring company’s stock. For this purpose, all performance criteria, if any, underlying unvested awards are deemed to be satisfied at 100% of target. The amount in this column for vesting of equity compensation awards assumes hypothetically that each applicable trigger under the CIC Plan occurred on December 31, 2020, and in the case of vesting RSUs is based on the closing price of the Company’s common stock of $13.64 on December 31, 2020 and in the case of vesting option awards is based on $13.64 minus the exercise price of the applicable option.

6 months

COBRA amounts are estimated based on medical, dental, and vision amounts paid by Company on behalf of the Named Executive and amounts paid by the Named Executive.

In the case of unvested equity compensation where the amount payable is based on the
satisfaction of performance criteria, the amount of unvested equity will be determined by
deeming all performance criteria satisfied at 100% target; to the extent the equity
compensation is subject to the IRC Section 409A, the vesting acceleration of the equity
compensation shall not cause any distribution or payment under the equity compensation to be
made before the earliest date it may be made without violating the IRC Section 409A.

CEO Pay Ratio

For

The severance benefits are contingent upon the 2020 fiscal year,employee meeting certain eligibility
requirements, including delivering to the ratioCompany a general release.  Because it may be
difficult for the Company’s executive officers to find comparable employment following a
termination without cause, these severance benefits are intended to ease the consequences to
an executive officer of an unexpected termination of employment.  The Company also believes
that having such arrangements in place can help the Company attract and retain key employees
in a marketplace where these types of arrangements are commonly offered by its peer
companies.

(ii) Eligible Employee is not terminated for a “Non-Qualifying Reason,” each as determined by
the Plan Administrator in its sole discretion.  For clarity, a “Qualifying Termination” shall include
the situation where the Eligible Employee is notified of an involuntary termination without
“Cause” as defined in the CIC Plan, as amended and in effect at the time of their termination,
and which is not for a “Non-Qualifying Reason,” followed by an agreement between the Eligible
Employee and the Employer to have the employee voluntarily resign their employment with
Employer.  In order for an involuntary termination to qualify, the termination of employment
must occur with respect to employment with all entities in the Plan Sponsor’s controlled group
as determined under the rules of IRC Section 414, as modified by IRC Section 409A.
“Non-Qualifying Reason” means either (i) the Eligible Employee voluntarily terminates
their employment for whatever reason (except when such voluntary termination of
employment is based on an agreement with Employer following notice by Employer to the
Eligible Employee of a “Qualifying Termination”); or (ii) the Eligible Employee separates from
Employer for whatever reason, and (a) Eligible Employee accepts any position with Employer
that begins prior to the effective date of their employment termination with Employer, or (b) a
comparable position with Employer is offered to the Eligible Employee prior to the effective
date of their employment termination with Employer.  For comparison of internal positions, a
comparable position is a position determined by the Plan Administrator as having the same or
higher base salary or which is paid no more than 15% lower in base salary than the employee’s
terminated position.

performance vesting awards, held by a participant will vest and become exercisable immediately prior to
termination.  The amount in this column for vesting of our employees other than our Chief Executive Officer (“Median Annual Compensation”) toequity compensation awards assumes hypothetically
that each applicable trigger under the annual total compensationSeverance Plan occurred on December 31, 2023, and in the case of
vesting RSUs is based on the closing price of the Company’s common stock of $18.84 on December 31, 2023

medical, dental and vision amounts paid by the Company on behalf of the NEO and amounts paid by the NEO.

under the data and assumptions summarized below. In this summary, we refer to the employee who received such Median Annual Compensation, who was selected in a manner consistent with Item 402(u) of Regulation S-K, as the “Median Employee.” For purposes of this disclosure, the date used to identify the Median Employee was December 31, 2020 (the “Determination Date”).

manner that does not create risks that are reasonably likely to have a material adverse effect
on the Company.  The CEO Compensation for purposes of this disclosure representsCommittee considered, among other factors, the sum of the total compensation reported for Mr. Mao under “Summary Compensation Table” for the 2020 fiscal year. For purposes of this disclosure, Median Annual Compensation was $86,138 and was calculated by totaling for our Median Employee all applicable elements

Financial Performance Measures
As described in greater detail in “Compensation Discussion and Analysis” above, the
Company’s executive compensation program reflects a variable pay-for-performance
philosophy.  The metrics that the Company uses for both of the long-term and short-term
incentive awards are selected based on an objective of incentivizing the Company’s executive
officers to increase the value of the Company’s enterprise for the Company’s stockholders.
While the Company uses numerous financial and non-financial performance measures for the
purpose of evaluating performance for its compensation programs, the following is an
unranked list of financial performance measures the Company considers the most important in
linking the compensation actually paid to the Company’s NEOs for 2023 with the Company’s
performance:
Revenue
Gross margin
Operating expenses
Operating income
Earnings per share

CEO Pay Ratio
For fiscal year 2023, the ratio of the median of the annual total compensation of all of the
Company’s employees other than the Company’s President and CEO (“Median Annual
Compensation”) to the combined annual total compensation of Mr. Moon, the Company’s
current President and CEO, and Mr. Mao, the Company’s former President and former CEO,
(“CEO Compensation”) was 16.92 to 1.  This ratio is a reasonable estimate calculated in a
manner consistent with Item 402(u) of Regulation S‑K using the data and assumptions
summarized below.  In this summary, the Company refers to the employee who received such
Median Annual Compensation, who was selected in a manner consistent with Item 402(u) of
Regulation S-K, as the “Median Employee.”  For purposes of this disclosure, the date used to
identify the Median Employee was December 31, 2023 (the “Determination Date”) and the
2023 Median Annual Compensation was $126,265, which was calculated by totaling all
applicable elements of compensation of the Company’s Median Employees in accordance with
Item 402(c)(2)(x) of Regulation S‑K for fiscal year 2023.
When calculating the Median Annual Compensation, the Company first determined its
U.S. and non-U.S. employee population as of the Determination Date.  The Company then
measured the compensation of these 253 employees, which represented all full-time
employees using the employee’s 1) annualized base wage; 2) value of equity compensation
awarded; and 3) non-equity compensation earned in 2023.
Energy Recovery, Inc.2024 Proxy Statement | 80

annualized base salary for Mr. Moon and Mr. Mao prorated for the period of service reported
for Mr. Moon and Mr. Mao under the “Base Salaries of Named Executive Officers Table” and

Proposal No. 3 – Ratification of Appointment of Independent
Registered Public Accounting Firm
The Audit Committee has appointed Deloitte & Touche LLP as the Company’s independent
registered public accounting firm for the fiscal year ending December 31, 2024.  Deloitte &
Touche LLP has served as the Company’s auditors since 2018.  A representative of Deloitte &
Touche LLP is expected to be present at the virtual 2024 Annual Meeting.  The representative
will have an opportunity to make a statement and to respond to any questions.
The Audit Committee recognizes the importance of maintaining the independence of the
Company’s independent auditor, both in fact and appearance.  Each year, the Audit Committee
evaluates the qualifications, performance and independence of the Company’s independent
auditor and determines whether to re-engage the current independent auditor.  In doing so,
the Audit Committee considers the quality and efficiency of the services provided by the
auditors, the auditors’ (global) capabilities and the auditors’ technical expertise and knowledge
of the Company’s operations and industry.  Based on this evaluation, the Audit Committee has
retained Deloitte & Touche LLP as the Company’s Independent Auditor for fiscal year 2024.  The
members of the Audit Committee and the Board believe that, due to Deloitte & Touche LLP’s
knowledge of the Company and of the industries in which the Company operate, it is in the
Company and the Company’s stockholder’s best interest to retain Deloitte & Touche LLP to
serve as its independent auditor during fiscal year 2024.
Principal Accountant Fees and Services
The following table sets forth all fees accrued or paid to Deloitte & Touche LLP, the
Company’s independent registered public accountants for fiscal years ended December 31,

Audit Committee Pre-Approval of Audit and Permissible Non-Audit
Services of Independent Registered Public Accounting Firm
The Audit Committee pre-approves audit, audit-related, tax and all other services
provided by the Company’s independent registered public accountants, Deloitte & Touche LLP,
and will not approve services that are impermissible under applicable laws and regulations.  The
pre-approval of services may be delegated to one or more of the Audit Committee’s members,
but the decision of that member to pre-approve specific services must be reported to the full
Audit Committee at its next scheduled meeting.  In the fiscal years ended December 31, 2023
and 2022, all fees identified above under the caption “Audit Fees” that were billed by Deloitte &
Touche LLP for 2023 and 2022 were approved by the Audit Committee in accordance with SEC
requirements.
In the fiscal years ended December 31, 2023 and 2022, there were no other professional
services provided by Deloitte & Touche LLP, other than those listed above, that would have
required the Audit Committee to consider their compatibility with maintaining the
independence of Deloitte & Touche LLP.
Ratification of Deloitte & Touche LLP
Although ratification is not required, the appointment of Deloitte & Touche LLP as the
Company’s independent auditors for fiscal year 2024 is being submitted for ratification at the
2024 Annual Meeting because the Board believes doing so is a good corporate governance
practice.  Furthermore, the Audit Committee will take stockholders’ opinions regarding the
appointment of Deloitte & Touche LLP into consideration in future deliberations.  If Deloitte &
Touche LLP’s appointment is not ratified at the 2024 Annual Meeting, the Audit Committee will
consider the engagement of other independent auditors.  The Audit Committee may terminate
Deloitte & Touche LLP’s engagement as the Company’s independent accountants without the
approval of the Company’s stockholders whenever the Audit Committee deems appropriate.

directors.  Abstentions are treated as shares present or represented and international mergersvoting regarding

Q:I share an address with another stockholder, and we received only one paper copy of the

Brokers with account holders who are the Company’s stockholders may be house-holding
the Company’s proxy materials.  A single set of proxy materials may be delivered to multiple
stockholders sharing an address unless contrary instructions have been received from the
affected stockholders.  Once you have received notice from your broker that it will be
