Eastman Chemical's stock surged 5.61% during intraday trading on Friday, following the release of positive forward-looking financial guidance and an analyst upgrade.

The company forecast second-quarter adjusted earnings per share in the range of $1.70 to $1.90, assuming stable consumer demand. The guidance reflects an expectation for substantially higher Chemical Intermediates spreads, which is expected to offset approximately $45 million in planned maintenance costs. Furthermore, Eastman announced price actions targeting about $500 million in increases for the remainder of 2026 to offset higher raw material and distribution costs.

Adding to the positive sentiment, Mizuho raised its price target on Eastman Chemical to $85 from $80 while maintaining an Outperform rating on the shares. This analyst action, combined with the company's optimistic outlook for capital spending reductions and operating cash flow, contributed to the significant upward movement in the stock price.
