The 5.0% stock rise reflects investor approval of volume growth and margin expansion driven by supply tightness and pricing power, particularly in Chemical Intermediates and specialty plastics amid global supply constraints.

• Chemical Intermediates sales volumes are growing due to improved asset availability post large cracker turnarounds and reduced imports from Asia, supporting higher margins.
• Middle East supply disruptions have tightened the market, allowing Eastman to shift exports from Asia to higher-value regions like Europe.
• Specialty plastics, including methanolysis-based products and rPET, continue to see strong revenue growth (~4-5%), with customers accepting price premiums despite a challenged end market.
• Pricing power benefits stem from competitors facing materially higher feedstock and energy costs, particularly in Asia, and emerging supply shortages expected to drive additional volume upside later in the year.
• Management notes modest end market demand conditions but highlights persistent customer willingness to pay for differentiated, sustainable products.
