🔎 What This Document Is

This is a "DEFA14A" filing, which stands for "Definitive Additional Materials." It's not the full, official proxy statement. Think of it as an important notice and summary sent to shareholders to tell them the full meeting materials are ready and explain how to access them and vote.

👉 In simple terms: It’s a "Your annual meeting is coming up, and here’s everything you need to know to participate" announcement from the company.

🗳️ The 4 Proposals to Vote On

The company's Board of Directors recommends you vote FOR all of the following items:

1. 👥 Election of Directors: You are voting to elect 8 people to the company's board. The nominees are: Thomas R. Bates, Jr., Christian A. Garcia, John F. Glick, Angela D. John, Sharon B. McGee, Brady M. Murphy, Julia A. Sloat, and Shawn D. Williams.

2. 💼 Advisory Vote on Executive Compensation: This is a non-binding "say-on-pay" vote where shareholders express their opinion on how the company compensates its top executives.

3. 🧾 Ratification of Auditor: You are being asked to officially approve the selection of Grant Thornton LLP as the company's independent accounting firm for the year. This is a standard annual procedure.

4. ✅ Ratification of a Tax Plan Amendment: You are voting to approve an amendment to the company's "Tax Benefits Preservation Plan." This type of plan is often used to help protect certain tax assets by discouraging large, sudden purchases of company stock.

📝 How to Access Materials & Vote

⚖️ Big Picture: Strengths & Risks

• 👍 Strength (Procedural): This notice shows the company is following standard governance protocols by clearly informing shareholders of the meeting, proposals, and voting methods.
• ⚠️ Risk (Contextual): The need to ratify an amendment to the Tax Benefits Preservation Plan (Proposal 4) might signal defensive measures are in place, which can sometimes be a point of contention for investors. The energy sector's volatility also underlies the company's performance.

🧠 The Analogy

This document is like the detailed "save the date" and instruction email for a very important school parent-teacher conference. It tells you when and where the meeting is, lists the specific topics (teacher evaluations, budget approval) you'll vote on, and shows you how to RSVP or send in your vote ahead of time. The full report card and detailed agenda (the proxy statement) are available online if you want to review them before making decisions.

🧩 Final Takeaway

This is a procedural notice for TETRA Technologies' 2026 annual shareholder meeting. The key actions for shareholders are to access the full materials online, review the four proposals (including director elections and auditor ratification), and cast their votes by the May 21 deadline.
