🧾 What This Document Is

This is a definitive additional soliciting material filing, often called a DEFA14A. Think of it as an official update or flyer sent to shareholders after the main proxy statement has been mailed.

👉 In simple terms: BigBear.ai is using this filing to announce and explain a new program aimed at making it easier for everyday investors (like those using Robinhood) to vote their shares. It’s not the main list of things to vote on, but rather instructions and details for a specific voting tool.

🏢 What The Company Does

BigBear.ai Holdings, Inc. (ticker: BBAI) is a company that provides artificial intelligence and machine learning solutions, primarily for government and commercial clients.

👉 In simple terms: They build complex data analysis and decision-support software. Imagine a high-tech analyst that can sift through mountains of information to help organizations spot patterns and make better choices.

🚀 Key Moves: The Retail Voting Program

The core of this document is the launch of a Retail Voting Program through the Robinhood platform.

How it works:

1. Opt-In: BigBear.ai shareholders who hold their stock in a Robinhood account can choose to join this program.
2. Vote with the Board: If they enroll, their shares will automatically be voted in line with the recommendations of BigBear.ai's Board of Directors on all matters at future shareholder meetings.
3. Easy Enrollment: The filing includes step-by-step instructions, screenshots, and FAQs on how shareholders can sign up via email and the Robinhood app.

Why it matters: Companies want high shareholder turnout for votes. This program simplifies the process for a large segment of retail investors, potentially increasing the number of votes cast and aligning them with management's perspective.

🔍 The Details: Program Mechanics & FAQs

The filing contains the actual instructional materials sent to shareholders, which include:

• The enrollment email announcement.
• Screenshots of what the stock detail and voting pages look like in Robinhood for users who are and are not signed up.
• A full page of Frequently Asked Questions (FAQs) to address potential investor concerns about the program.

👉 Key takeaway: This is a hands-on guide designed to drive participation by removing complexity. The company is actively soliciting (hence "soliciting material") votes through this new, streamlined channel.

📅 Key Dates & Contact Information

The materials were first distributed to stockholders on April 10, 2026.

For any questions, the filing directs shareholders to:

• Email: [email protected]
• Website: https://ir.bigbear.ai/ (SEC Filings page)
• SEC Website: All official filings are available at www.sec.gov.

⚖️ Big Picture: Strengths & Risks

• 👍 Strength (Governance): This program is a proactive effort to improve corporate governance by boosting retail investor engagement and participation in the voting process.
• ⚠️ Consideration (Passive Voting): The program relies on shareholders trusting the board's recommendations. It centralizes voting power with the board's directives, which is efficient but reduces independent judgment from participating retail voters.

🧠 The Analogy

It's like your friend group is deciding where to go for dinner. Instead of everyone texting ideas back and forth, one person (the Board) researches the best options and makes a recommendation. This program is like you telling that friend, "Just pick for me—I trust your judgment," so the group can reach a decision faster.

🧩 Final Takeaway

BigBear.ai is launching a voluntary program to simplify voting for its Robinhood-based shareholders, allowing them to automatically align their votes with the company's board. This move aims to increase voter turnout and streamline corporate governance, reflecting a modern approach to engaging with a retail investor base.
