Celltrion

Dear Valued Shareholders,

Due to external market factors such as growing geopolitical uncertainties in the Middle East, increased volatility in global oil prices, and concentrated capital flows into select sectors within global equity markets, the biotechnology and pharmaceutical sectors as a whole are not being sufficiently valued by the market. Celltrion’s corporate value likewise remains significantly undervalued relative to the meaningful business achievements and strong fundamentals the Company has demonstrated.

Management recognizes the seriousness of the current situation and is closely reviewing the prevailing market environment and the potential risk of shareholder value deterioration. Should these circumstances persist, the Company and its major shareholders plan to comprehensively consider various measures aimed at enhancing shareholder value.

Celltrion continues to execute its mid- to long-term roadmap without disruption, including the expansion of its core biosimilar business, advancement of novel drug pipelines, and strengthening of global market share. In particular, the achievement of record-high first-quarter revenue and improved profitability further demonstrates that the Company’s fundamentals are stronger than ever.

In addition, as Celltrion operates a primarily export-driven business model, foreign exchange fluctuations do not represent a material risk factor for the Company. Furthermore, given that our business portfolio is centered on therapeutics, which generally exhibit low sensitivity to economic cycles, we believe the likelihood of any meaningful deterioration in our fundamentals remains very low.

Celltrion will continue to dedicate its utmost efforts toward strengthening business competitiveness and securing a sustainable foundation for long-term growth. The Company also plans to share its second-quarter results with shareholders as promptly and transparently as possible.

At the same time, we will continue to closely monitor market conditions and pursue bold and unwavering shareholder-friendly policies that meet the expectations of our shareholders.

We sincerely appreciate your continued trust and support.

Thank you.
