Celltrion

Dear Valued Shareholders,

We would like to extend our sincere appreciation to all shareholders for your continued trust and support for Celltrion, even amid recent market volatility and uncertainty.

Following the announcement of our “Shareholder Value Enhancement Plan” on May 21, we have received numerous inquiries regarding the detailed timeline. Accordingly, we would like to provide further clarification as outlined below.

▲ Bonus Share Issuance 

(Ex-rights Date: June 4, 2026 / Record Date: June 5, 2026 / Listing Date: June 30, 2026)

Celltrion will proceed with a bonus share issuance this year, following last year’s initiative. The planned issuance is approximately 10.92 million shares, significantly exceeding last year’s approximately 8.49 million shares. Shareholders will be allotted 0.05 new shares per existing common share. The record date for the bonus issuance is June 5, 2026 (based on settlement date), meaning that shareholders who acquire shares by June 2 will be eligible. The ex-rights date will be June 4, and the newly issued shares are scheduled to be listed on June 30.

▲ Share Buyback (Purchases available from June 8, 2026)

Celltrion plans to repurchase treasury shares worth KRW 100 billion to support stock price stability and enhance shareholder value. In accordance with Article 176-2 of the Enforcement Decree of the Financial Investment Services and Capital Markets Act, the buyback period will run for up to three months starting from June 8, 2026. The company intends to execute purchases in a timely manner, taking market conditions into consideration.

▲ Employee Stock Ownership Plan (ESOP) Subscription (Expected to begin in early June 2026)

Based on strong confidence in Celltrion’s mid- to long-term growth and future value, employees will participate as key stakeholders in responsible management through stock purchases. The subscription process for the employee stock ownership plan is currently underway, with actual purchases expected to commence in early June 2026.

▲ Acquisition of Shares by Major Shareholder Celltrion Holdings (Purchases available from June 18, 2026)

Celltrion’s largest shareholder, Celltrion Holdings, plans to acquire approximately KRW 100 billion worth of Celltrion shares. Through this transaction, the major shareholder aims to demonstrate strong commitment to responsible management while reinforcing corporate value. The acquisition is expected to be completed within 30 days from June 18, 2026, in accordance with Article 200-3 of the Enforcement Decree of the Capital Markets Act.

Celltrion will continue to make every effort to strengthen its business competitiveness and secure a foundation for sustainable growth. We also plan to share our second-quarter earnings with shareholders as swiftly and transparently as possible.

At the same time, we will closely monitor market conditions and continue to implement decisive and consistent shareholder-friendly policies that meet shareholder expectations.

We sincerely appreciate your continued trust and support.

Thank you.
