💰 The 2026 Buyback Program Announcement 🚀

The most significant announcement is the formal approval of the new "2026 Buyback Program." A share buyback allows a company to purchase its own shares from the open market. This reduces the total number of outstanding shares, which generally increases earnings per share (EPS) and signals confidence in the stock.

The Board of Directors approved this program on April 21, 2026, following an ordinary General Shareholders’ Meeting held on March 24, 2026.

• Total Buyback Cap: The program allows for the purchase of common shares, preferred shares, and American Depositary Receipts (ADRs) up to COP$1,350,000,000,000 (one trillion three hundred fifty billion Colombian pesos).
• Term: This massive buyback is structured to run for a three-year period, starting from the approval date until April 21, 2029.

👉 This long-term, large-scale commitment suggests Grupo Cibest plans to use its capital to support its stock price and manage its equity base over the next three years.

🛑 Termination of the 2025 Buyback Program 🛑

Grupo Cibest is simultaneously confirming the termination of its previous buyback initiative, the "2025 Buyback Program." Corporate buyback programs have defined start and end dates, and this filing officially closes the book on the prior agreement.

The program was originally approved at an extraordinary General Shareholders’ Meeting on June 9, 2025.

• What was executed: Under the 2025 Program, the company successfully bought back shares totaling 601,452 common shares and 12,164,612 preferred shares (of which 5,137,320 corresponded to ADRs).
• Total Spending: To date, the company spent COP 690,022 million pesos on these buybacks.
• Execution Rate: This execution represents 51.11% of the total amount approved for the 2025 Buyback Program, showing significant progress toward the prior goal.

👉 The confirmation of the 2025 termination provides a clean break, allowing the company to fully dedicate its focus and resources to the larger, newer 2026 plan.

🧠 The Analogy

Think of a company's shares like marbles in a jar. When a company announces a "buyback," it's like the company reaching into the jar and buying those marbles back. By removing those marbles from circulation, the company makes the total number of marbles (shares) smaller. This is like giving every remaining marble slightly more value, thus boosting the perceived value or earnings per marble (share). The 2026 Program is simply restocking the plan to remove a massive pile of marbles over the next three years.

🧩 Final Takeaway

Grupo Cibest S.A. is aggressively committing to capital return, launching a major three-year buyback program of up to COP$1.35 trillion, while formally closing its previous buyback agreement. This signals strong management confidence in the company's future value to its shareholders.
