Eastman’s leadership highlighted a multifaceted plan to stabilize its Fibers business following a challenging year. CEO Mark Costa attributed approximately 40% of the segment’s year-over-year EBIT decline to non-tow factors: a $30 million tariff-related drop in textiles, a $20 million headwind from reduced internal cellulosics demand and $50 million in elevated utilization and energy costs. Tow volumes have been stabilized in customer contracts, although achieved with modest price concessions to align with market levels. Management expects customer destocking to persist through the year, with first-quarter volumes starting light and building later under normal back-half seasonality. Additional levers include $125 million to $150 million of company-wide cost reductions this year (on top of $100 million realized in 2025), expanded staple-fiber efforts beyond Naia filament and volume ramp-up in Aventa applications such as food trays and straws.

Costa identified the ethylene-to-propylene (E2P) project as the primary structural improvement in the Chemical Intermediates segment. By converting bulk ethylene into propylene, the project is projected to reduce earnings volatility, replace higher-cost purchased propylene and enhance propylene margins. Depending on market spread levels, the initiative could boost annual earnings by $50 million to $100 million with a payback period under two years. Current CI profitability remains hampered by weak end-market demand and global oversupply pressures, particularly from low-cost Chinese exports. Over half of CI output is consumed internally by Eastman’s specialty businesses, offering a pathway to substitute low-value exports with higher-margin internal sales as specialty demand recovers.

In explaining guidance for the first quarter, management noted the difficult comparison against a strong prior-year period that preceded a mid-year demand downturn. They forecast modest volume improvement sequentially into early 2026 driven by seasonal strength in Advanced Materials and Additives & Functional Products, reduced pre-tariff inventory distortions and fewer CI shutdowns. Offsetting factors include higher energy costs, pricing resets in CI and modest tow price declines. The outlook assumes ongoing customer destocking, with volume ramp-up concentrated in the back half of the year.

The Advanced Materials segment is benefiting from volume growth—particularly in circular solutions—cost reductions and improved utilization as inventory actions unwind. Management acknowledged modest pricing declines as they share raw-material cost benefits with customers, but expect variable margin expansion from favorable mix. Circular investments include a paused second methanolysis plant pending a more capital-efficient design and a debottlenecking project at Kingsport that could raise capacity by 130%. Eastman emphasized that chemical recycling delivers polymer quality on par with virgin resin and cited strategic brand partnerships, including with a major beverage company, to drive rPET volume growth.
