🔖 What This Document Is

This is a "definitive additional material" (DEFA14A) filing. Think of it as a friendly reminder and instruction manual for a company's upcoming shareholder vote. It's not the full, detailed proxy statement, but a "get out the vote" notice that summarizes the key meeting details and how to cast your ballot. It's filed with the SEC to make sure all shareholders get the information they need to participate.

🏢 What The Company Does

👉 In simple terms, United Community Banks, Inc. (UCBI) is a regional bank. It provides common banking services—like taking deposits, making loans, and offering wealth management—to individuals and businesses, primarily in the Southeastern United States. As a publicly traded company, its shareholders (the owners) get to vote on important matters each year.

📅 The Annual Meeting: Key Details

Your chance to vote as a shareholder is at the 2026 Annual Meeting.

• When: May 13, 2026, at 3:00 PM Eastern Time.
• Where: Virtually on the internet at www.virtualshareholdermeeting.com/UCBI2026.
• Voting Deadline: You must cast your vote by May 12, 2026, at 11:59 PM ET. (If your shares are in a plan, vote by May 10). 👉 Why it matters: This isn't a physical meeting. You'll log in online, and your vote—whether cast in advance or during the meeting—is crucial for electing leadership and guiding the company.

🗳️ What You're Voting On

There are three main items on the ballot this year. The company's Board of Directors recommends voting "FOR" on all of them.

1. Elect the Board of Directors: You are voting to elect 12 individuals to the company's board. These are the people who oversee management and make major strategic decisions for the bank.
2. Approve Executive Pay (Advisory): This is a non-binding vote to approve the compensation of the company's top executives. It's a way for shareholders to voice their opinion on whether the pay packages are fair and align with performance.
3. Ratify the Auditor: This is a routine vote to confirm the appointment of PricewaterhouseCoopers LLP as the company's independent accounting firm for 2026. They are the ones who will audit the bank's financial books.

🧠 The Analogy

Voting your shares is like being a part-owner of a local credit union. Each year, the credit union holds a meeting where you get to help choose the board members, give your opinion on the manager's pay, and confirm the outside auditor. This document is your mailed reminder of that meeting, telling you the date, what's on the agenda, and exactly how you can cast your ballot—even if you can't attend in person.
