👥 Board Composition & Structure ⚖️

The Board of Directors is the ultimate supervisory body—it hires, oversees, and holds management accountable. The company places high value on diverse experience, and the structure is designed to ensure checks and balances.

Independent Oversight: The Board is designed with strong checks and balances. Five of the six continuing directors are independent (meaning they are not employees or executives of the Company). This separation of power protects the shareholders' interests.
Committee Oversight: There are three standing, independent committees:
- Audit Committee (Chair: A. J. Buehler): Oversees financial integrity, internal controls, and the auditor's performance.
- Compensation Committee (Chair: Joan K. Chow): Manages executive pay, ensuring compensation rewards long-term performance.
- Nominating & Corporate Governance Committee (Chair: Colin R. Sabol): Manages director selection, Board refreshment, and overall governance policies.
Board Leadership Structure: The Board maintains a separation of powers: Pamela L. Tondreau is the Chair of the Board, while David W. Moon is the President and CEO.
- Why it matters: Separating the CEO and the Board Chair is considered best practice because it gives the independent Board Chair the freedom to question and challenge management without direct conflict.

🧑‍⚖️ Director Nominees and Qualifications 🏅

The Board recommends six directors for election for one-year terms, emphasizing a balance between seasoned veterans and new perspectives. The selection process is guided by finding directors with diverse skills relevant to the company’s complex operations.

The Nominees: The Board recommends that shareholders vote "FOR" the following six individuals:
- Alexander J. Buehler (Age 50)
- Joan K. Chow (Age 65)
- Arve Hanstveit (Age 71)
- David W. Moon (Age 64)
- Colin R. Sabol (Age 58)
- Pamela L. Tondreau (Age 66)
Experience Snapshot: The directors bring a highly diverse, comprehensive skillset, covering multiple vital areas:
- Technical Expertise: Deep experience in water, energy, manufacturing, and global process technology.
- Financial Savvy: Expertise in global financial markets, corporate strategy, and financial auditing.
- Industry Breadth: Significant leadership roles at major companies in resource management and infrastructure (e.g., Xylem, Carrier Global).
Qualifications: The Board stated that the selection process considers board refreshment, the individual's background, and their ability to provide "different skills, experiences, expertise, backgrounds and points of view" to enhance strategic discussions.

💵 Executive Compensation Philosophy 💰

This section addresses how the company plans to pay its leaders, demonstrating a clear philosophy of aligning pay with performance. The goal is to reward growth and risk-taking behavior over time.

The Core Philosophy: The Company's compensation is intended to be "variable, at-risk compensation." This means a substantial portion of executive pay is not guaranteed and depends on achieving specific performance goals.
Key Pillars of Pay:
- At-Risk Pay: A large part of compensation is contingent upon achieving targets.
- Long-Term Vesting: Incentives require service over time (long-term vesting), promoting retention and commitment to the company's sustained success.
- Risk Management: Policies include a clawback policy (allowing the company to reclaim compensation if misconduct is found) and a double-trigger change in control severance (only payable if two specific events occur, ensuring management remains highly engaged).
Prohibited Practices: The company explicitly states what it will not do, including: no repricing of equity, no guaranteed bonuses, and no excessive perquisites, reinforcing transparency and prudence.

🚨 Corporate Governance & Oversight Principles 🛡️

ERII's governance policies show a sophisticated, proactive approach to managing risk. The Board has established multiple layers of oversight, recognizing that modern risk is complex and spans more than just financial reporting.

The Core Principle: The Company’s governance framework is designed to promote transparency and ensure the Board can review business operations and make decisions that are independent of management, always in the stockholders' best interest.
Key Governance Policies:
- Board Evaluations: The Board and its committees conduct regular self-assessments to continuously improve their effectiveness.
- Director Independence: The Board confirms that, except for the CEO (David W. Moon), all current directors and nominees are considered "independent."
- Prohibited Transactions: The company maintains stringent guidelines prohibiting directors from hedging or pledging company stock, which protects the common stock value.
Cybersecurity Governance: The Board takes cyber risks seriously, establishing oversight mechanisms to ensure that cybersecurity considerations are integrated into the company’s overall strategy. The Audit Committee bears the primary responsibility for this domain.

🌱 Sustainability and Ethics Commitments 🌎

Modern corporate governance requires addressing non-financial topics like environment, social impact, and ethics. ERII outlines clear commitments in these areas, which also boosts its market standing.

The Approach: The sustainability approach integrates measurable targets for the company's own operational footprint alongside delivering customer solutions that promote sustainable growth.
The Commitments: Oversight of sustainability is handled by the Nominating & Corporate Governance Committee.
Key Achievements:
- The company received a high rating of AAA from MSCI ESG Research LLC as of March 2026.
- Why it matters: Receiving this high rating in the Industrial Machinery sector signals to investors that ERII has robust corporate governance, strong labor practices, and is positioned favorably for the clean technology transition.

🧠 The Analogy

Think of the Board of Directors as the captain and senior officers of a massive cargo ship (Energy Recovery, Inc.). The Proxy Statement is like the company's official captain's logbook for the year. It doesn't tell you how many barrels of oil were shipped (that's the profit report); instead, it shows you: Who is running the ship (the nominees), Who gets paid for steering the ship (compensation), How they are prevented from making illegal moves (governance rules), and If the ship is crewed by ethical and skilled people (ESG commitments).

🧩 Final Takeaway

This filing confirms that ERII prioritizes a highly structured, independent, and well-governed board. The focus on strong governance, high ESG ratings, and transparent compensation structures suggests the company is built for long-term stability and accountability.
