Item 7.01. Regulation FD Disclosure. Green Plains Inc. (“the Company”) in its most recently filed annual report on Form 10-K for the year ended December 31, 2023, reported its operating financial results through three reportable segments: Ethanol Production, Agribusiness and Energy Services, and Partnership. As a result of the completion of the transactions contemplated by the previously announced Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which the Company acquired all of the publicly held common units of Green Plains Partners LP (the “Partnership”) not already owned by the Company and its affiliates on January 9, 2024, the Company’s Chief Executive Officer (“CEO”), who is the Chief Operating Decision Maker (“CODM”), began reviewing the Company’s financial information through two reportable segments. As such, effective for the first quarter of 2024, the Company updated its management reports as reviewed by the CODM and revised its reportable segments from three to two, which are as follows: Ethanol Production and Agribusiness and Energy Services. The changes in the Company’s reportable segments presentation include the following: •The revenue and operating results from fuel storage and transportation services previously disclosed within the Partnership segment are now included within the Ethanol Production segment. •Intersegment activities between the Partnership and Green Plains Trade associated with ethanol storage and transportation services previously treated like third-party transactions and eliminated on a consolidated level are now eliminated within the Ethanol Production segment. Intersegment activities between the Partnership and Green Plains Trade associated with terminal services transacted with the Agribusiness and Energy Services segment will continue to be eliminated on a consolidated level. Selected restated segment financial data reflecting the segments change for the three months ended March 31, 2023, June 30, 2023, September 30, 2023, and the three and twelve months ended December 31, 2023 is incorporated her
