On April 27, 2023, the registrant publicly released its financial results for first quarter 2023. The full text of the release is furnished as Exhibit 99.01 to this Current Report on Form 8-K, and is incorporated herein by reference. This information shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

Item 7.01    Regulation FD Disclosure

Unaudited Financial Information Recast for Changes in the Additives & Functional Products Segment and the Chemical Intermediates Segment

Starting in first-quarter 2023, Eastman integrated the functional amines product line into the Additives & Functional Products ("AFP") segment. In addition, organic acid products and some olefin-based products previously reported in the AFP segment are now being managed under the Chemical Intermediates segment. Because the operating results of the new segments for prior years will not be reported until the Form 10-Q is filed for each quarter of 2023, and the Form 10-K for 2023, management desires to provide more timely information to investors to enhance understanding of operating performance of the Company's adjusted segments. Therefore, Exhibit 99.02 to this Current Report on Form 8-K presents selected quarterly unaudited financial information recast for changes in segments for the years ended December 31, 2022, 2021, 2020, and 2019 to supplement financial disclosures included in the Company's previously filed reports and to recast previously disclosed segment financial information under the new reporting structure. The recast of the previous segment financial information is not a restatement of previous financial statements and does not affect the Company's consolidated reported net income, earnings per share, operating income, or total assets or liabilities for any of the previously reported periods. This information shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.
