Basis Of Presentation, Description Of Business And Summary Of Significant Accounting Policies	1. BASIS OF PRESENTATION, DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES References to the Company References to “Green Plains” or the “company” in the consolidated financial statements and in these notes to the consolidated financial statements refer to Green Plains Inc., an Iowa corporation, and its subsidiaries. Consolidated Financial Statements The consolidated financial statements include the company’s accounts and all significant intercompany balances and transactions are eliminated. Unconsolidated entities are included in the financial statements on an equity basis. The company owns a 48.9 % limited partner interest and a 2.0 % general partner interest in Green Plains Partners LP. Public investors own the remaining 49.1 % limited partner interest in the partnership. The company determined that the limited partners in the partnership with equity at risk lack the power, through voting rights or similar rights, to direct the activities that most significantly impact the partnership’s economic performance; therefore, the partnership is considered a variable interest entity. The company, through its ownership of the general partner interest in the partnership, has the power to direct the activities that most significantly affect economic performance and is obligated to absorb losses and has the right to receive benefits that could be significant to the partnership. Therefore, the company is considered the primary beneficiary and consolidates the partnership in the company’s financial statements. The assets of the partnership cannot be used by the company for general corporate purposes. The partnership’s consolidated total assets as of June 30, 2021 and December 31, 2020, excluding intercompany balances, are $ 92.4 million and $ 91.2 million, respectively, and primarily consist of property and equipment, operating lease right-of-use assets and goodwill. The partnership’s consolidated total liabilities as of June 30, 2021 and December 31, 2020, excluding intercompany balances, are $ 105.4 million and $ 151.2 million, respectively, which primarily consist of long-term debt as discussed in Note 8 – Debt and operating lease liabilities. The liabilities recognized as a result of consolidating the partnership do not represent additional claims on our general assets. The company also owns a majority interest in BioProcess Algae, a joint venture formed in 2008 as well as a majority interest in Fluid Quip Technologies, LLC with their results being consolidated in our consolidated financial statements. The accompanying unaudited consolidated financial statements are prepared in accordance with GAAP for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Because they do not include all of the information and notes required by GAAP, the consolidated financial statements should be read in conjunction with the company’s annual report on Form 10-K for the year ended December 31, 2020, filed with the SEC on February 16, 2021. The unaudited financial information reflects adjustments, which are, in the opinion of management, necessary for a fair presentation of results of operations, financial position and cash flows for the periods presented. The adjustments are normal and recurring in nature, unless otherwise noted. Interim period results are not necessarily indicative of the results to be expected for the entire year. Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation. These reclassifications did not affect total revenues, costs and expenses or net income. See Note 8 – Debt and Note 11 – Stockholders’ Equity for further details. Revision of Previously Issued Financial Statements During the third quarter of 2020, the company reported an overstatement of both revenues and cost of goods sold by approximately $ 30.0 million within the agribusiness and energy services segment as previously reported for the three and six months ended June 30, 2020. Revenues and cost of goods sold for the three and six months ended June 30, 2020 have been revised to reflect these amounts. Use of Estimates in the Preparation of Consolidated Financial Statements The preparation of consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. The company bases its estimates on historical experience and assumptions it believes are proper and reasonable under the circumstances and regularly evaluates the appropriateness of its estimates and assumptions. Actual results could differ from those estimates. Key accounting policies, including but not limited to those relating to revenue recognition, carrying value of intangible assets, operating leases, impairment of long-lived assets and goodwill, derivative financial instruments, accounting for income taxes and assets acquired and liabilities assumed in acquisitions, are impacted significantly by judgments, assumptions and estimates used in the preparation of the consolidated financial statements. Description of Business The company operates within four business segments: (1) ethanol production, which includes the production of ethanol, including industrial-grade alcohol, distillers grains, Ultra-High Protein and corn oil, (2) agribusiness and energy services, which includes grain handling and storage, commodity marketing and merchant trading for company-produced and third-party ethanol, distillers grains, corn oil, natural gas and other commodities, (3) food and ingredients, which includes food-grade corn oil and (4) partnership, which includes fuel storage and transportation services. The food and ingredients segment had no activity during the three and six months ended June 30, 2021 and 2020. Cash and Cash Equivalents Cash and cash equivalents includes bank deposits as well as short-term, highly liquid investments with original maturities of three months or less. Restricted Cash The company has restricted cash, which can only be used for funding letters of credit, for payment towards a revolving credit agreement, or for capital expenditures as specified in certain credit facility agreements. Restricted cash also includes cash margins and securities pledged to commodity exchange clearinghouses and at times, funds in escrow related to acquisition and disposition activities. To the degree these segregated balances are cash and cash equivalents, they are considered restricted cash on the consolidated balance sheets. Revenue Recognition The company recognizes revenue when obligations under the terms of a contract with a customer are satisfied. Generally, this occurs with the transfer of control of products or services. Revenue is measured as the amount of consideration expected to be received in exchange for transferring goods or providing services. Sales, value add, and other taxes the company collects concurrent with revenue-producing activities are excluded from revenue. Sales of ethanol, distillers grains, corn oil, natural gas and other commodities by the company’s marketing business are recognized when obligations under the terms of a contract with a customer are satisfied. Generally, this occurs with the transfer of control of products or services. Revenues related to marketing for third parties are presented on a gross basis as the company controls the product prior to the sale to the end customer, takes title of the product and has inventory risk. Unearned revenue is recorded for goods in transit when the company has received payment but control has not yet been transferred to the customer. Revenues for receiving, storing, transferring and transporting ethanol and other fuels are recognized when the product is delivered to the customer. The company routinely enters into physical-delivery energy commodity purchase and sale agreements. At times, the company settles these transactions by transferring its obligations to other counterparties rather than delivering the physical commodity. Energy trading transactions are reported net as a component of revenue. Revenues include net gains or losses from derivatives related to products sold while cost of goods sold includes net gains or losses from derivatives related to commodities purchased. Revenues also include realized gains and losses on related derivative financial instruments and reclassifications of realized gains and losses on cash flow hedges from accumulated other comprehensive income or loss. Sales of products, including agricultural commodities, are recognized when control of the product is transferred to the customer, which depends on the agreed upon shipment or delivery terms. Revenues related to grain merchandising are presented gross and include shipping and handling, which is also a component of cost of goods sold. Revenues from grain storage are recognized over time as the services are rendered. Revenues related to the design, engineering and installation of equipment are recognized over the term of the related contracts as equipment is delivered and installed and services are performed. A substantial portion of the partnership revenues are derived from fixed-fee commercial agreements for storage, terminal or transportation services. The partnership recognizes revenue upon transfer of control of product from its storage tanks and fuel terminals, when railcar volumetric capacity is provided, and as truck transportation services are performed. To the extent shortfalls associated with minimum volume commitments in the previous four quarters continue to exist, volumes in excess of the minimum volume commitment are applied to those shortfalls. Remaining excess volumes generating operating lease revenue are recognized as incurred. Shipping and Handling Costs The company accounts for shipping and handling activities related to contracts with customers as costs to fulfill its promise to transfer the associated products. Accordingly, the company records customer payments associated with shipping and handling costs as a component of revenue, and classifies such costs as a component of cost of goods sold. Cost of Goods Sold Cost of goods sold includes direct labor, materials, shipping and plant overhead costs. Direct labor includes all compensation and related benefits of non-management personnel involved in ethanol production. Grain purchasing and receiving costs, excluding labor costs for grain buyers and scale operators, are also included in cost of goods sold. Materials include the cost of corn feedstock, denaturant, and process chemicals. Corn feedstock costs include gains and losses on related derivative financial instruments not designated as cash flow hedges, inbound freight charges, inspection costs and transfer costs, as well as reclassifications of gains and losses on cash flow hedges from accumulated other comprehensive income or loss. Plant overhead consists primarily of plant utilities, repairs and maintenance and outbound freight charges. Shipping costs incurred by the company, including railcar costs, are also reflected in cost of goods sold. The company uses exchange-traded futures and options contracts and forward purchase and sale contracts to attempt to minimize the effect of price changes on ethanol, grain and natural gas. Exchange-traded futures and options contracts are valued at quoted market prices and settled predominantly in cash. The company is exposed to loss when counterparties default on forward purchase and sale contracts. Grain inventories held for sale and forward purchase and sale contracts are valued at market prices when available or other market quotes adjusted for basis differences, primarily in transportation, between the exchange-traded market and local market where the terms of the contract is based. Changes in forward purchase contracts and exchange-traded futures and options contracts are recognized as a component of cost of goods sold. Operations and Maintenance Expenses In the partnership segment, transportation expenses represent the primary component of operations and maintenance expenses. Transportation expenses include railcar leases, freight and shipping of the company’s ethanol and co-products, as well as costs incurred storing ethanol at destination terminals. Derivative Financial Instruments The company uses various derivative financial instruments, including exchange-traded futures and exchange-traded and over-the-counter options contracts, to attempt to minimize risk and the effect of commodity price changes including but not limited to, corn, ethanol, natural gas, soybean meal and soybean oil. The company monitors and manages this exposure as part of its overall risk management policy to reduce the adverse effect market volatility may have on its operating results. The company may hedge these commodities as one way to mitigate risk; however, there may be situations when these hedging activities themselves result in losses. By using derivatives to hedge exposures to changes in commodity prices, the company is exposed to credit and market risk. The company’s exposure to credit risk includes the counterparty’s failure to fulfill its performance obligations under the terms of the derivative contract. The company minimizes its credit risk by entering into transactions with high quality counterparties, limiting the amount of financial exposure it has with each counterparty and monitoring their financial condition. Market risk is the risk that the value of the financial instrument might be adversely affected by a change in commodity prices or interest rates. The company manages market risk by incorporating parameters to monitor exposure within its risk management strategy, which limits the types of derivative instruments and strategies the company can use and the degree of market risk it can take using derivative instruments. The company evaluates its physical delivery contracts to determine if they qualify for normal purchase or sale exemptions which are expected to be used or sold over a reasonable period in the normal course of business. Contracts that do not meet the normal purchase or sale criteria are recorded at fair value. Changes in fair value are recorded in operating income unless the contracts qualify for, and the company elects, cash flow hedge accounting treatment. Certain qualifying derivatives related to ethanol production and agribusiness and energy services are designated as cash flow hedges. The company evaluates the derivative instrument to ascertain its effectiveness prior to entering into cash flow hedges. Unrealized gains and losses are reflected in accumulated other comprehensive income or loss until the gain or loss from the underlying hedged transaction is realized and the physical transaction is completed. When it becomes probable a forecasted transaction will not occur, the cash flow hedge treatment is discontinued, which affects earnings. These derivative financial instruments are recognized in current assets or current liabilities at fair value. At times, the company hedges its exposure to changes in inventory values and designates qualifying derivatives as fair value hedges. The carrying amount of the hedged inventory is adjusted in the current period for changes in fair value. Estimated fair values carried at market are based on exchange-quoted prices, adjusted as appropriate for regional location basis values, which represent differences in local markets, including transportation as well as quality or grade differences. Basis values are generally determined using inputs from broker quotations or other market transactions. However, a portion of the value may be derived using unobservable inputs. Ineffectiveness of the hedges is recognized in the current period to the extent the change in fair value of the inventory is not offset by the change in fair value of the derivative. Recent Accounting Pronouncements On January 1, 2021, the company early adopted the amended guidance in ASC 470-20 , Debt - Debt with Conversion and Other Options and ASC 815-40 , Derivatives and Hedging - Contracts in Entity’s Own Equity - Accounting for Convertible Instruments and Contracts in an Equity’s Own Equity. The adoption of this guidance resulted in a $ 49.5 million decrease in additional paid-in capital, an $ 11.4 million increase in retained earnings and a $ 38.1 million increase in long-term debt, which included a $ 39.4 million increase in debt principal offset by a $ 1.3 million increase in debt issuance costs, resulting from amounts previously bifurcated to equity being reclassified to debt. See Note 8 – Debt and Note 11 – Stockholders’ Equity for further details. In March 2020, the FASB issued amended guidance in ASC 848, Reference Rate Reform - Facilitation of the Effects of Reference Rate Reform on Financial Reporting, and a subsequent update in January 2021, which provides optional expedients and exceptions to U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burden related to the expected market transition from the LIBOR and other interbank offered rates to alternative reference rates. The expedients and exceptions provided by the amended guidance do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The guidance is effective upon issuance and to be applied prospectively from any date beginning March 12, 2020 through December 31, 2022. The amended guidance is not expected to have a material impact on the company’s consolidated financial statements. In December 2019, the FASB issued amended guidance in ASC 740, Income Taxes - Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 74 0. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of ASC 740 by clarifying and amending existing guidance. The amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption of the amendments is permitted. The company is evaluating the impact of this standard on its consolidated financial statements.

Acquisitions And Dispositions [Abstract]
Acquisitions And Dispositions	3. ACQUISITIONS AND DISPOSITIONS Acquisition of a Majority Interest in Fluid Quip Technologies, LLC On December 9, 2020, the company acquired a majority interest in Fluid Quip Technologies, LLC. During the second quarter of 2021, the company identified additional information through analysis of the final FQT acquisition agreements that resulted in a reassessment of certain contingent considerations related to potential earn-out payments which identified an understatement of other long term assets by $ 16.7 million, accrued liabilities of $ 2.4 million, long term other liabilities of $ 12.4 million and noncontrolling interests of $ 1.9 million as previously reported within ethanol production segment as of March 31, 2021 and December 31, 2020. Disposition of Ord Ethanol Plant On March 22, 2021, the company completed the sale of the plant located in Ord, Nebraska and certain related assets, to GreenAmerica Biofuels Ord LLC (the “Ord Transaction”) for a sale price of $ 64.0 million, plus working capital of $ 9.8 million. Correspondingly, the company entered into a separate asset purchase agreement with the Partnership to acquire the storage assets and assign the rail transportation assets to be disposed of in the Ord Transaction for $ 27.5 million, which was used to pay down a portion of the partnership’s credit facility. The divested assets were reported within the company’s ethanol production, agribusiness and energy services and partnership segments. The company recorded a pretax gain on the sale of the Ord plant of $ 35.9 million within corporate activities. The asset and liabilities of the Ord ethanol plant at closing on March 22, 2021 were as follows: (in thousands): Amounts of Identifiable Assets Disposed and Liabilities Relinquished Inventory $ 10,400 Prepaid expenses and other 632 Property and equipment 24,285 Accrued and other liabilities ( 156 ) Total identifiable net assets disposed $ 35,161 The amounts reflected above represent working capital estimates, which are considered preliminary until contractual post-closing working capital adjustments are finalized. The operating lease right-of-use assets and lease liabilities associated with the railcar operating leases, currently estimated at approximately $ 1.8 million, respectively, will be extinguished upon the assignment of the associated leases to GreenAmerica Biofuels Ord LLC, which occurred in July of 2021. Disposition of Hereford Ethanol Plant On December 28, 2020, the company completed the sale of the plant located in Hereford, Texas, and certain related assets, to Hereford Ethanol Partners, L.P. There were no material changes to the assets disposed and liabilities relinquished from the disposition of the Hereford plant during the three and six months ended June 30, 2021. Disposition of Equity Interest in Green Plains Cattle Company LLC On October 1, 2020, pursuant to the Securities Purchase Agreement, the company sold its remaining 50 % joint venture interest in GPCC to AGR, TGAM Agribusiness Fund LP and StepStone (the “Buyers”) for $ 80.5 million in cash, plus closing adjustments. The transaction resulted in a reduction in other assets of $ 69.7 million as a result of the removal of the equity method investment in GPCC, and a reduction in accumulated other comprehensive income (loss) of $ 10.7 million as a result of the removal of the company’s share of equity method investees accumulated other comprehensive loss. Transaction fees related to the disposal were not material. There was no material gain or loss recorded as part of this transaction. The Securities Purchase Agreement contains certain earn-out provisions of up to $ 4.0 million to be paid to the Buyers if certain EBITDA thresholds are met.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	4 . FAIR VALUE DISCLOSURES The following methods, assumptions and valuation techniques were used in estimating the fair value of the company’s financial instruments: Level 1 – unadjusted quoted prices in active markets for identical assets or liabilities the company can access at the measurement date. Level 2 – directly or indirectly observable inputs such as quoted prices for similar assets or liabilities in active markets other than quoted prices included within Level 1, quoted prices for identical or similar assets in markets that are not active, and other inputs that are observable or can be substantially corroborated by observable market data through correlation or other means. Grain inventories held for sale in the agribusiness and energy services segment are valued at nearby futures values, plus or minus nearby basis values, which represent differences in local markets including transportation or commodity quality or grade differences. Level 3 – unobservable inputs that are supported by little or no market activity and comprise a significant component of the fair value of the assets or liabilities. The company currently does not have any recurring Level 3 financial instruments. Derivative contracts include exchange-traded commodity futures and options contracts and forward commodity purchase and sale contracts. Exchange-traded futures and options contracts are valued based on unadjusted quoted prices in active markets and are classified in Level 1. The majority of the company’s exchange-traded futures and options contracts are cash-settled on a daily basis. There have been no changes in valuation techniques and inputs used in measuring fair value. The company’s assets and liabilities by level are as follows (in thousands): Fair Value Measurements at June 30, 2021 Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs (Level 1) (Level 2) Total Assets: Cash and cash equivalents $ 496,932 $ - $ 496,932 Restricted cash 118,441 - 118,441 Inventories carried at market - 50,617 50,617 Unrealized gains on derivatives - 41,377 41,377 Other assets 111 43 154 Total assets measured at fair value $ 615,484 $ 92,037 $ 707,521 Liabilities: Accounts payable (1) $ - $ 19,488 $ 19,488 Accrued and other liabilities (2) - 2,424 2,424 Unrealized losses on derivatives - 12,579 12,579 Other liabilities (2) - 12,498 12,498 Total liabilities measured at fair value $ - $ 46,989 $ 46,989 Fair Value Measurements at December 31, 2020 Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs (Level 1) (Level 2) Total Assets: Cash and cash equivalents $ 233,860 $ - $ 233,860 Restricted cash 40,950 - 40,950 Inventories carried at market - 77,900 77,900 Unrealized gains on derivatives - 21,956 21,956 Other assets 112 29 141 Total assets measured at fair value $ 274,922 $ 99,885 $ 374,807 Liabilities: Accounts payable (1) $ - $ 19,355 $ 19,355 Unrealized losses on derivatives - 10,997 10,997 Total liabilities measured at fair value $ - $ 30,352 $ 30,352 (1) Accounts payable is generally stated at historical amounts with the exception of $ 19.5 million and $ 19.4 million at June 30, 2021 and December 31, 2020, respectively, related to certain delivered inventory for which the payable fluctuates based on changes in commodity prices. These payables are hybrid financial instruments for which the company has elected the fair value option. (2) As of June 30, 2021, accrued and other liabilities includes $ 2.4 million and other liabilities includes $ 12.5 million of consideration related to potential earn-out payments recorded at fair value. The fair value of the company’s debt was approximately $ 759.8 million compared with a book value of $ 726.2 million, excluding debt issuance costs, at June 30, 2021. The fair value of the company’s debt was approximately $ 535.9 million compared with a book value of $ 526.2 million at December 31, 2020. The company estimated the fair value of its convertible notes using Level 1 inputs, and the fair value of its other outstanding debt using Level 2 inputs . The company believes the fair values of its accounts receivable approximated book value, which was $ 80.3 million and $ 55.6 million at June 30, 2021 and December 31, 2020, respectively. Although the company currently does not have any recurring Level 3 financial measurements, the fair values of tangible and intangible assets and goodwill acquired represent Level 3 measurements which were derived using a combination of the income approach, market approach and cost approach for the specific assets or liabilities being valued.

Segment Information [Abstract]
Segment Information	5. SEGMENT INFORMATION The company reports the financial and operating performance for the following four operating segments: (1) ethanol production, which includes the production of ethanol, including industrial-grade alcohol, distillers grains, Ultra-High Protein and corn oil, (2) agribusiness and energy services, which includes grain handling and storage, commodity marketing and merchant trading for company-produced and third-party ethanol, distillers grains, corn oil, natural gas and other commodities, (3) food and ingredients, which includes food-grade corn oil and (4) partnership, which includes fuel storage and transportation services. The food and ingredients segment, had no activity during the three and six months ended June 30, 2021 and 2020. Corporate activities include selling , general and administrative expenses, consisting primarily of compensation, professional fees and overhead costs not directly related to a specific operating segment. During the normal course of business, the operating segments conduct business with each other. For example, the agribusiness and energy services segment procures grain and natural gas and sells products, including ethanol, distillers grains and corn oil for the ethanol production segment. The partnership segment provides fuel storage and transportation services for the ethanol production segment. These intersegment activities are treated like third-party transactions with origination, marketing and storage fees charged at estimated market values. Consequently, these transactions affect segment performance; however, they do not impact the company’s consolidated results since the revenues and corresponding costs are eliminated. The following tables set forth certain financial data for the company’s operating segments (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 Revenues: Ethanol production: Revenues from external customers $ 555,273 $ 290,517 $ 978,995 $ 766,217 Intersegment revenues - 25 - 50 Total segment revenues 555,273 290,542 978,995 766,267 Agribusiness and energy services: Revenues from external customers 167,975 96,123 296,796 252,004 Intersegment revenues 5,512 4,368 10,635 11,676 Total segment revenues 173,487 100,491 307,431 263,680 Partnership: Revenues from external customers 1,170 1,384 2,267 2,672 Intersegment revenues 18,531 18,997 37,840 37,980 Total segment revenues 19,701 20,381 40,107 40,652 Revenues including intersegment activity 748,461 411,414 1,326,533 1,070,599 Intersegment eliminations ( 24,043 ) ( 23,390 ) ( 48,475 ) ( 49,706 ) Total Revenues $ 724,418 $ 388,024 $ 1,278,058 $ 1,020,893 Refer to Note 2 - Revenue , for further disaggregation of revenue by operating segment.

Debt [Abstract]
Debt	8. DEBT On January 1, 2021, the company early adopted the amended guidance in ASC 470-20 , using the modified retrospective method of transition. The adoption of this guidance resulted in a $ 49.5 million decrease in additional paid-in capital, an $ 11.4 million increase in retained earnings and a $ 38.1 million increase in long-term debt, which included a $ 39.4 million increase in debt principal offset by a $ 1.3 million increase in debt issuance costs, resulting from amounts previously bifurcated to equity being reclassified to debt.

Subsequent to June 30, 2021, the partnership refinanced its credit facility. See Note 15 – Subsequent Events for further details. The components of short-term notes payable and other borrowings are as follows (in thousands): June 30, 2021 December 31, 2020 Green Plains Trade: $ 300.0 million revolver $ 100,769 $ 79,251 Green Plains Grain: $ 100.0 million revolver 55,000 38,700 $ 50.0 million inventory financing - - Green Plains Commodity Management: $ 30.0 million hedge line 18,239 21,682 Other - 1,175 $ 174,008 $ 140,808 Corporate Activities In March 2021, the company issued an aggregate $ 230.0 million of 2.25 % convertible senior notes due in 2027, or the 2.25 % notes. The 2.25 % notes bear interest at a rate of 2.25 % per year, payable on March 15 and September 15 of each year, beginning September 15, 2021, and mature on March 15, 2027 . The 2.25 % notes are senior, unsecured obligations of the company. The 2.25 % notes are convertible, at the option of the holders, into consideration consisting of, at the company’s election, cash, shares of the company’s common stock, or a combination of cash and stock (and cash in lieu of fractional shares). However, before September 15, 2026, the 2.25 % notes will not be convertible unless certain conditions are satisfied. The initial conversion rate is 31.6206 shares of the company’s common stock per $ 1,000 principal amount of 2.25 % notes (equivalent to an initial conversion price of approximately $ 31.62 per share of the company’s common stock), representing an approximately 37.5 % premium over the offering price of the company’s common stock. The conversion rate is subject to adjustment upon the occurrence of certain events, including but not limited to; the event of a stock dividend or stock split; the issuance of additional rights, options and warrants; spinoffs; the event of a cash dividend or distribution; or a tender or exchange offering. In addition, the company may be obligated to increase the conversion rate for any conversion that occurs in connection with certain corporate events, including the company’s calling the 2.25 % notes for redemption. On and after March 15, 2024, and prior to the maturity date, the company may redeem, for cash, all, but not less than all, of the 2.25 % notes if the last reported sale price of the company’s common stock equals or exceeds 140 % of the applicable conversion price on (i) at least 20 trading days during a 30 consecutive trading day period ending on the trading day immediately prior to the date the company delivers notice of the redemption; and (ii) the trading day immediately before the date of the redemption notice. The redemption price will equal 100 % of the principal amount of the 2.25 % notes to be redeemed, plus any accrued and unpaid interest to, but excluding, the redemption date. In addition, upon the occurrence of a “fundamental change” (as defined in the indenture for the 2.25 % notes), holders of the 2.25 % notes will have the right, at their option, to require the company to repurchase their 2.25 % notes for cash at a price equal to 100 % of the principal amount of the 2.25 % notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. During June 2019, the company issued an aggregate $ 115.0 million of 4.00 % convertible senior notes due in 2024, or the 4.00 % notes. The 4.00 % notes are senior, unsecured obligations of the company, with interest payable on January 1 and July 1 of each year, beginning January 1, 2020, at a rate of 4.00 % per annum. The 4.00 % notes will mature on July 1, 2024 , unless earlier converted, redeemed or repurchased. The 4.00 % notes will be convertible, at the option of the holders, into consideration consisting of, at the company’s election, cash, shares of the company’s common stock, or a combination of cash and shares of the company’s common stock until the close of business on the scheduled trading day immediately preceding the maturity date. However, before January 1, 2024, the 4.00 % notes will not be convertible unless certain conditions are satisfied. The initial conversion rate is 64.1540 shares of common stock per $ 1,000 of principal, which is equal to a conversion price of approximately $ 15.59 per share. The conversion rate will be subject to adjustment upon the occurrence of certain events, including but not limited to; the event of a stock dividend or stock split; the issuance of additional rights, options and warrants; spinoffs; the event of a cash dividend or distribution; or a tender or exchange offering. In addition, the company may be obligated to increase the conversion rate for any conversion that occurs in connection with certain corporate events, including the company’s calling the 4.00 % notes for redemption. On and after July 1, 2022, and prior to the maturity date, the company may redeem all, but not less than all, of the 4.00 % notes for cash if the sale price of the company’s common stock equals or exceeds 140 % of the applicable conversion price for a specified time period ending on the trading day immediately prior to the date the company delivers notice of the redemption. The redemption price will equal 100 % of the principal amount of the 4.00 % notes to be redeemed, plus any accrued and unpaid interest to, but excluding, the redemption date. In addition, upon the occurrence of a fundamental change, holders of the 4.00 % notes will have the right, at their option, to require the company to repurchase the 4.00 % notes in cash at a price equal to 100 % of the principal amount of the 4.00 % notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. During May 2021, the company entered into a privately negotiated agreement with certain noteholders of the company’s 4.00 % notes. Under this agreement, 3,568,705 shares of the company’s common stock were exchanged for $ 51.0 million in aggregate principal amount of the 4.00 % notes. Common stock held as treasury shares were exchanged for the 4.00 % notes. Pursuant to the guidance within ASC 470, Debt , the company recorded a loss of $ 9.5 million which was recorded as a charge to interest expense in the consolidated financial statements during the three months ended June 30, 2021, of which $ 1.2 million related to unamortized debt issuance costs. In August 2016, the company issued $ 170.0 million of 4.125 % convertible senior notes due in 2022, or the 4.125 % notes. The 4.125 % notes are senior, unsecured obligations of the company, with interest payable on March 1 and September 1 of each year. The company may settle the 4.125 % notes in cash, common stock or a combination of cash and common stock. Prior to March 1, 2022, the 4.125 % notes are not convertible unless certain conditions are satisfied. The initial conversion rate is 35.7143 shares of common stock per $ 1,000 of principal, which is equal to a conversion price of approximately $ 28.00 per share. The conversion rate will be subject to adjustment upon the occurrence of certain events, including but not limited to; the event of a stock dividend or stock split; the issuance of additional rights, options and warrants; spinoffs; the event of a cash dividend or distribution; or a tender or exchange offering. The company may redeem all, but not less than all, of the 4.125 % notes at any time on or after September 1, 2020, if the company’s common stock equals or exceeds 140 % of the applicable conversion price for a specified time period ending on the trading day immediately prior to the date the company delivers notice of the redemption. The redemption price will equal 100 % of the principal plus any accrued and unpaid interest. Holders of the 4.125 % notes have the option to require the company to repurchase the 4.125 % notes in cash at a price equal to 100 % of the principal plus accrued and unpaid interest when there is a fundamental change, such as change in control. If an event of default occurs, it could result in the 4.125 % notes being declared due and payable. In March 2021, concurrent with the issuance of the 2.25 % notes, the company used approximately $ 156.5 million of the net proceeds of the 2.25 % notes to repurchase approximately $ 135.7 million aggregate principal amount of the 4.125 % notes, in privately negotiated transactions. Pursuant to the guidance within ASC 470, Debt , the company recorded a loss upon extinguishment of $ 22.1 million. This charge included $ 1.2 million of unamortized debt issuance costs related to the principal balance extinguished.

The company also has small equipment financing loans, finance leases on equipment or facilities, and other forms of debt financing. Partnership Segment Green Plains Partners has a $ 135.0 million credit facility to fund working capital, capital expenditures and other general partnership purposes. The credit facility includes a $ 130.0 million term loan and a $ 5.0 million revolver, and matures on December 31, 2021 . The partnership made $ 46.8 million in principal payments on the term loan during the six months ended June 30, 2021, including $ 16.3 million of scheduled repayments, $ 27.5 million related to the sale of the storage assets located adjacent to the Ord, Nebraska ethanol plant and a $ 3.0 million prepayment made with excess cash. As of June 30, 2021, no additional prepayments on the term loan were required. Monthly principal payments of $ 2.5 million were required through April 15, 2021, with a step up to monthly payments of $ 3.2 million beginning May 15, 2021 through maturity. In addition, if at any time subsequent to July 15, 2020, the partnership’s cash balance exceeds $ 2.5 million for more than five consecutive business days, prepayments of outstanding principal are required in an amount equal to the excess cash. The partnership is also required to prepay outstanding principal on the credit facility with 100 % of net cash proceeds from any asset disposition or recovery event. Any prepayments on the term loan are applied to the remaining principal balance in inverse order of maturity, including the final payment. The term loan balance, and any advances on the revolver, are subject to a floating interest rate based on a 1.0% LIBOR floor plus 4.50 % to 5.25 % dependent upon the preceding fiscal quarter’s consolidated leverage ratio. Prepayments of $ 40.0 million in excess of the scheduled monthly payments were made prior to April 1, 2021, and as such, the interest rate associated with the term loan balance was not increased to a floating rate based on a 1.00 % LIBOR floor plus 5.00 % to 5.75 %. The unused portion of the revolver is also subject to a commitment fee of 0.50 %. The credit facility also allows for swing line loans subject to the revolver availability. Swing line loans are subject to a floating interest rate based on the Prime Rate plus 3.5 % to 4.25 % dependent upon the preceding fiscal quarter’s consolidated leverage ratio. Under the terms of the credit facility, swing line loans must be repaid within 10 days of the date of the advance. As of June 30, 2021, the term loan had a balance of $ 53.2 million and an interest rate of 5.50 %, and there were no outstanding swing line loans. The partnership’s obligations under the credit facility are secured by a first priority lien on (i) the equity interests of the partnership’s present and future subsidiaries, (ii) all of the partnership’s present and future personal property, such as investment property, general intangibles and contract rights, including rights under any agreements with Green Plains Trade, and (iii) all proceeds and products of the equity interests of the partnership’s present and future subsidiaries and its personal property and (iv) substantially all of the partnership’s real property and material leases of real property. The terms impose affirmative and negative covenants, including restrictions on the partnership’s ability to incur additional debt, acquire and sell assets, create liens, invest capital, pay distributions and materially amend the partnership’s commercial agreements with Green Plains Trade. The credit facility also requires the partnership to maintain a maximum consolidated leverage ratio and a minimum consolidated debt service coverage ratio , each of which is calculated on a pro forma basis with respect to acquisitions and divestitures occurring during the applicable period. The maximum consolidated leverage ratio required, as of the end of any fiscal quarter, is no more than 3.00 x and decreases 0.25 x each quarter to 1.50 x by December 31, 2021. The minimum consolidated debt service coverage ratio for the three months ended March 31, 2021, was set to 1.05 x due to the partnership having completed prepayment of at least $ 40 million of the outstanding principal balance on the credit facility as specified in the loan agreement. The minimum debt service coverage ratio resumed being set to 1.10 x for subsequent quarters. The consolidated leverage ratio is calculated by dividing total funded indebtedness by the sum of the four preceding fiscal quarters’ consolidated EBITDA. The consolidated debt service coverage ratio is calculated by taking the sum of the four preceding fiscal quarters’ consolidated EBITDA minus income taxes and consolidated capital expenditures for such period divided by the sum of the four preceding fiscal quarters’ consolidated interest charges plus consolidated scheduled funded debt payments for such period. Under the amended terms of the credit facility, the partnership may make quarterly distribution payments in an aggregate amount not to exceed $ 0.12 per outstanding unit, so long as (i) no default has occurred and is continuing, or would result from payment of the distribution, and (ii) the partnership and its subsidiaries are in compliance with its financial covenants and remain in compliance after payment of the distribution. The credit facility is not guaranteed by the company. Subsequent to June 30, 2021, the partnership amended its credit facility. Please refer to Note 15 – Subsequent Events for further details. Covenant Compliance The company was in compliance with its debt covenants as of June 30, 2021. Restricted Net Assets At June 30, 2021, there were approximately $ 169.4 million of net assets at the company’s subsidiaries that could not be transferred to the parent company in the form of dividends, loans or advances due to restrictions contained in the credit facilities of these subsidiaries.

The company records noncash compensation expense related to equity awards in its consolidated financial statements over the requisite period on a straight-line basis. Restricted Stock Awards and Deferred Stock Units The non-vested stock award and deferred stock unit activity for the six months ended June 30, 2021, is as follows: Non-Vested Shares and Deferred Stock Units Weighted- Average Grant- Date Fair Value Weighted-Average Remaining Vesting Term (in years) Non-Vested at December 31, 2020 1,028,739 $ 9.15 Granted 344,689 27.07 Forfeited ( 53,958 ) 13.82 Vested ( 456,412 ) 11.45 Non-Vested at June 30, 2021 863,058 $ 14.80 2.1 Performance Shares On February 18, 2021 and March 18, 2020, the board of directors granted performance shares to be awarded in the form of common stock to certain participants of the plan. These performance shares vest based on the level of achievement of certain performance goals, including the incremental value achieved from the company’s high-protein initiatives, annual production levels and return on investment (ROI). Performance shares granted in 2021 and 2020 do not contain market based factors requiring a Monte Carlo valuation model. The performance shares were granted at a target of 100 %, but each performance share will reduce or increase depending on results for the performance period. If the company achieves the maximum performance goals, the maximum amount of shares available to be issued pursuant to the 2021 and 2020 awards are 1,094,205 performance shares which represents approximately 275 % of the 398,102 performance shares which remain outstanding. The actual number of performance shares that will ultimately vest is based on the actual performance targets achieved at the end of the performance period. On February 19, 2019 and March 19, 2018, the board of directors granted performance shares to be awarded in the form of common stock to certain participants of the plan. These performance shares vest based on the company’s average return on net assets (RONA) and the company’s total shareholder return (TSR), as further described herein. The performance shares vest on the third anniversary of the grant, if the RONA and TSR criteria are achieved and the participant is then employed by the company. Fifty percent of the performance shares vest based upon the company’s ability to achieve a predetermined RONA during the three year performance period. The remaining fifty percent of the performance shares vest based upon the company’s total TSR during the three year performance period relative to that of the company’s performance peer group. The performance shares were granted at a target of 100 %, but each performance share will reduce or increase depending on results for the performance period for the company's RONA, and the company’s TSR relative to that of the performance peer group. On March 19, 2021, based on criteria discussed above, the 2018 performance shares vested at a target of 75 %. If the company’s RONA and TSR achieve the maximum goals, the maximum amount of shares available to be issued pursuant to the 2019 awards are 242,501 performance shares or 150 % of the 161,667 performance shares which remain outstanding. The actual number of performance shares that will ultimately vest is based on the actual percentile ranking of the company’s RONA, and the company’s TSR compared to the peer performance at the end of the performance period. For performance shares which include market based factors, the company uses the Monte Carlo valuation model to estimate the fair value of the performance shares on the date of the grant. The weighted average assumptions used by the company in applying the Monte Carlo valuation model for performance share grants and related valuation are illustrated in the following table: FY 2019 Performance Awards Risk-free interest rate 2.45 % Dividend yield 3.13 % Expected volatility 41.69 % Monte Carlo valuation 99.62 % Closing stock price on the date of grant $ 15.34 The non-vested performance share award activity for the six months ended June 30, 2021, is as follows: Performance Shares Weighted- Average Grant- Date Fair Value Weighted-Average Remaining Vesting Term (in years) Non-Vested at December 31, 2020 517,969 $ 10.82 Granted 183,316 26.41 Forfeited ( 53,601 ) 20.91 Vested ( 87,915 ) 17.68 Non-Vested at June 30, 2021 559,769 $ 14.29 2.5 Green Plains Partners Green Plains Partners has a long-term incentive plan (LTIP) intended to promote the interests of the partnership, its general partner and affiliates by providing unit-based incentive compensation awards to employees, consultants and directors to encourage superior performance. The LTIP reserves 2,500,000 common limited partner units for issuance in the form of options, restricted units, phantom units, distribution equivalent rights, substitute awards, unit appreciation rights, unit awards, profit interest units or other unit-based awards. The partnership measures unit-based compensation at fair value on the grant date, with no adjustments for estimated forfeitures. The partnership records noncash compensation expense related to the awards over the requisite service period on a straight-line basis. The unit-based awards activity for the six months ended June 30, 2021, is as follows: Non-Vested Shares and Deferred Stock Units Weighted- Average Grant- Date Fair Value Weighted-Average Remaining Vesting Term (in years) Non-Vested at December 31, 2020 47,620 $ 6.72 Vested ( 47,620 ) 6.72 Non-Vested at June 30, 2021 - $ - 0.0 Stock-Based and Unit Based Compensation Expense Compensation costs for stock-b ased and unit-based payment plans were $ 1.1 million and $ 2.0 million for the three and six months ended June 30, 2021, respectively, and $ 2.3 million and $ 3.6 million for the three and six months ended June 30, 2020, respectively. At June 30, 2021, there was $ 14.8 million of unrecognized compensation costs from stock-based and unit-based compensation related to non-vested awards. This compensation is expected to be recognized over a weighted-average period of approximately 2.2 years. The potential tax benefit related to stock-based payment is approximately 23.9 % of these expe nses .

Earnings Per Share [Abstract]
Earnings Per Share	10. EARNINGS PER SHARE Basic earnings per share, or EPS, is calculated by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. The company computed diluted EPS by dividing net income on an if-converted basis, adjusted to add back net interest expense related to the convertible debt instruments, by the weighted average number of common shares outstanding during the period, adjusted to include the shares that would be issued if the convertible debt instruments were converted to common shares and the effect of any outstanding dilutive securities. The basic and diluted EPS are calculated as follows (in thousands, except per share amounts): Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 Basic EPS: Net income (loss) attributable to Green Plains $ 9,743 $ ( 8,214 ) $ 3,198 $ ( 24,659 ) Weighted average shares outstanding - basic 45,425 34,603 41,581 34,634 EPS - basic $ 0.21 $ ( 0.24 ) $ 0.08 $ ( 0.71 ) Diluted EPS: Net income (loss) attributable to Green Plains $ 9,743 $ ( 8,214 ) $ 3,198 $ ( 24,659 ) Interest and amortization on convertible debt, net of tax effect: 4.125 % convertible notes due 2022 - - - - 4.00 % convertible notes due 2024 577 - - - 2.25 % convertible notes due 2027 1,216 - - - Net income (loss) attributable to Green Plains - diluted $ 11,536 $ ( 8,214 ) $ 3,198 $ ( 24,659 ) Weighted average shares outstanding - basic 45,425 34,603 41,581 34,634 Effect of dilutive convertible debt: 4.125 % convertible notes due 2022 - - - - 4.00 % convertible notes due 2024 4,106 - - - 2.25 % convertible notes due 2027 7,273 - - - Effect of dilutive warrants 669 - 345 - Effect of dilutive stock-based compensation awards 698 - 749 - Weighted average shares outstanding - diluted 58,171 34,603 42,675 34,634 EPS - diluted $ 0.20 $ ( 0.24 ) $ 0.07 $ ( 0.71 ) Anti-dilutive weighted-average convertible debt and stock-based compensation (1) 1,226 14,074 10,233 13,994 (1) Anti-dilutive effects related to the company’s convertible debt and stock-based compensation awards are excluded from diluted EPS for certain periods presented. For the three months ended June 30, 2021, the company excluded the impact of the 4.125 % convertible notes due in 2022, and associated interest and amortization, as inclusion would be anti-dilutive. For the six months ended June 30, 2021, the company excluded the impact of the 4.125 % convertible notes due in 2022, 4.00 % convertible notes due in 2024 and the 2.25 % convertible notes due in 2027, and associated interest and amortization, as inclusion would be anti-dilutive. For the three and six months ended June 30, 2020, all convertible debt and stock-based compensation awards were excluded from diluted EPS as inclusion would be anti-dilutive.

Stockholders' Equity [Abstract]
Stockholders' Equity	11. STOCKHOLDERS’ EQUITY Early Adoption of ASC 470-20 On January 1, 2021, the company early adopted the amended guidance in ASC 470-20 , using the modified retrospective method of transition. The adoption of this guidance resulted in a $ 49.5 million decrease in additional paid-in capital, an $ 11.4 million increase in retained earnings and a $ 38.1 million increase in long-term debt, which included a $ 39.4 million increase in debt principal offset by a $ 1.3 million increase in debt issuance costs, resulting from amounts previously bifurcated to equity being reclassified to debt. Upon adoption of amended guidance in ASC 470-20 , the company reversed the remaining deferred tax liability of $ 9.2 million associated to the equity portion of previously issued convertible debt. As the company had recorded a full valuation allowance against its deferred tax assets, the reversal of the $ 9.2 million deferred tax liability would require an increase to the existing valuation allowance by the same amount, which would normally be recorded through current income tax expense. However, because the change in the deferred tax liability is directly linked to the adoption of ASC 470-20, which is accounted for as a cumulative effect adjustment, the required increase to the valuation allowance is recorded as part of the cumulative adjustment to stockholders’ equity and has no effect on the income statement. Public Offering of Common Stock On March 1, 2021, the company completed an offering of 8,751,500 shares of our common stock, par value $ 0.001 per share, in a public offering at a price of $ 23.00 per share (the “Common Stock Offering”). The Common Stock Offering resulted in net proceeds of $ 191.1 million, after deducting underwriting discounts and commissions as well as the company’s offering expenses. Warrants During the three months ended March 31, 2021, in connection with certain arrangements, the company issued warrants to purchase shares of its common stock. The company measures the fair value of the warrants using the Black-Scholes option pricing model as of the issuance date. Exercisable warrants are equity based and recorded as a reduction in additional paid-in capital. The company has reserved 2,550,000 shares of common stock for the exercise of warrants to non-employees, of which 2,275,000 are exercisable. The remaining 275,000 warrants are contingent upon certain earn-out provisions, treated as liability based awards, and valued quarterly using the company’s stock price. These warrants could potentially dilute basic earnings per share in future periods. The exercise price of the warrants is $ 22.00 and expiration dates are December 8, 2025 for 275,000 warrants, February 9, 2026 for 275,000 warrants and April 28, 2026 for 2,000,000 warrants. Convertible Note Exchange On May 18, 2021, the company closed on a privately negotiated exchange agreement with certain noteholders of the company’s 4.00 % notes , pursuant to which the noteholders agreed to exchange $ 51.0 million in aggregate principal for 3,568,705 shares of the company’s common stock at an implied price of $ 26.80 .

Income Taxes [Abstract]
Income Taxes	12. INCOME TAXES The company records actual income tax expense or benefit during interim periods rather than on an annual effective tax rate method. Certain items are given discrete period treatment and the tax effect of those items are reported in full in the relevant interim period. Green Plains Partners is a limited partnership, which is treated as a flow-through entity for federal income tax purposes and is not subject to federal income taxes. As a result, the consolidated financial statements do not reflect income taxes on pre-tax income or loss attributable to the noncontrolling interest in the partnership. The CARES Act was signed into law on March 27, 2020. The CARES Act includes several significant business tax provisions including elimination of the taxable limit for certain net operating losses (“NOL”), allowing businesses to carry back NOLs arising in 2018, 2019 and 2020 to the five prior tax years, accelerating refunds of previously generated corporate AMT credits , and loosening the business interest limitation under §163(j) from 30 % to 50 %. The CARES Act also contains an employee retention credit to encourage employers to maintain headcounts even if employees cannot report to work because of issues related to the COVID-19. In the first quarter of 2020, the company recorded an income tax benefit related to the expected NOL carry back claim of $ 28.4 million, which was an estimate based on the amount of NOL rated to the 2019 year-end tax provision. No additional tax benefit was recorded related to the CARES Act during the six months ended June 30, 2021. The company recorded income tax benefit of $ 4.8 million and $ 2.9 million for the three and six months ended June 30, 2021, compared with income tax benefit of $ 11.5 million and $ 55.7 million for the same periods in 2020. The decrease in income tax benefit recorded for the three months ended June 30, 2021 was primarily due to an increase in pretax book income for the period offset by the tax benefit for the utilization of previously recorded NOLs. The decrease in the amount of tax benefit recorded for the six months ended June 30, 2021 compared to the same period in 2020 was primarily due to the tax benefit recognized in 2020 associated with the carry back of the tax NOL generated in 2019 to the 2014 tax year under the newly enacted CARES Act. The amount of unrecognized tax benefits for uncertain tax positions was $ 51.4 million as of June 30, 2021 and $ 51.6 million as of June 30, 2020. The effective tax rate can be affected by variances in the estimates and amounts of taxable income among the various states, entities and activity types, realization of tax credits, adjustments from resolution of tax matters under review, valuation allowances and the company’s assessment of its liability for uncertain tax positions. Upon adoption of amended guidance in ASC 470-20, during the first quarter of 2021, the company reversed the remaining deferred tax liability of $ 9.2 million associated to the equity portion of previously issued convertible debt. As the company had recorded a full valuation allowance against its deferred tax assets, the reversal of the $ 9.2 million deferred tax liability would require an increase to the existing valuation allowance by the same amount which would normally be recorded through current income tax expense. However, as the change in the deferred tax liability is directly linked to the adoption of ASC 470-20, which is accounted for as a cumulative effect adjustment, the required increase to the valuation allowance is recorded as part of the cumulative adjustment to stockholders’ equity and has no effect on the consolidated statements of operations.

Commitments And Contingencies [Abstract]
Commitments And Contingencies	13. COMMITMENTS AND CONTINGENCIES Lease Expense The company leases certain facilities, parcels of land, and equipment, with remaining terms ranging from less than one year to 16.4 years. The land and facility leases include renewal options. The renewal options are included in the lease term only for those sites or locations in which they are reasonably certain to be renewed. Equipment renewals are not considered reasonably certain to be exercised as they typically renew with significantly different underlying terms. The company may sublease certain of its railcars to third parties on a short-term basis. The subleases are classified as operating leases, with the associated sublease income being recognized on a straight-line basis over the lease term. The components of lease expense are as follows (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 Lease expense Operating lease expense $ 4,908 $ 5,255 $ 9,842 $ 10,200 Variable lease expense (1) 522 630 591 899 Total lease expense $ 5,430 $ 5,885 $ 10,433 $ 11,099 (1) Represents amounts incurred in excess of the minimum payments required for a certain building lease and for the handling and unloading of railcars for a certain land lease, offset by railcar lease abatements provided by the lessor when railcars are out of service during periods of maintenance or upgrade.

The undiscounted amounts are not included in the tables above. Lease Revenue As described in Note 2 – Revenue , the majority of the partnership’s segment revenue is generated through their storage and throughput services and rail transportation services agreements with Green Plains Trade and are accounted for as lease revenue. Leasing revenues do not represent revenues recognized from contracts with customers under ASC 606, and are accounted for under ASC 842, Leases . Lease revenue associated with agreements with Green Plains Trade is eliminated upon consolidation. The remaining lease revenue is not material to the company. Refer to Note 2 – Revenue for further discussion on lease revenue. Commodities As of June 30, 2021, the company had contracted future purchases of grain, corn oil, natural gas, ethanol and distillers grains, valued at approximately $ 379.4 million. Legal The company is currently involved in litigation that has arisen during the ordinary course of business, but does not believe any pending litigation will have a material adverse effect on its financial position, results of operations or cash flows.

Related Party Transactions [Abstract]
Related Party Transactions	14. RELATED PARTY TRANSACTIONS Aircraft Leases The company entered into two agreements with an entity controlled by Wayne Hoovestol for the lease of two aircraft. Mr. Hoovestol is chairman of the company’s board of directors. Given the limited amount of travel during fiscal year 2020, the companies have agreed to defer the monthly payment until excess carryover hours are used. As of June 30, 2021, the company has approximately 44 hours of flight time available to be used. Once used, the company agreed to pay $ 11,588 per month for the combined use of up to 125 hours per year for the aircraft. Flight time in excess of 125 hours per year will incur additional hourly charges. Payments related to these leases totaled $ 14 thousand and $ 35 thousand during the three and six months ended June 30, 2021 and $ 0 and $ 24 thousand during the three and six months ended June 30, 2020, respectively. The company had no outstanding payables related to these agreements as of June 30, 2021 and December 31, 2020. Green Plains Cattle Company LLC The company engaged in certain related party transactions with GPCC, which was considered a related party until the fourth quarter of 2020 at which time the company’s remaining 50 % interest was sold. The company provided a variety of shared services to GPCC, including accounting and finance, payroll and human resources, information technology, legal, communications and treasury activities.

Subsequent Events	15. SUBSEQUENT EVENTS On July 20, 2021, the partnership entered into an Amended and Restated Credit Agreement (“Amended Credit Facility”) to its existing credit facility with funds and account managed by BlackRock (“BlackRock”) and TMI Trust Company as administrative agent. Under the terms of the agreement, BlackRock purchased the outstanding balance of the existing notes from Bank of America N.A., as previous administrative agent, and certain other commercial lending institutions. The Amended Credit Facility will mature on July 20, 2026 and the principal amount available is $ 60.0 million. As a result of the new maturity date, $ 50.0 million has been reclassified from current maturities of long-term debt to long-term debt as of June 30, 2021. Interest on the Amended Credit Facility is based on 3-month LIBOR plus 8.00 %, with a 0 % LIBOR floor. Interest is payable on the 15th day of each March, June, September and December during the term with the first interest payment being September 15, 2021. The Amended Credit Facility does not require any principal payments; however, the partnership has the option to prepay $ 1.5 million per quarter beginning twelve months following closing. Financial covenants of the agreement will include a maximum consolidated leverage ratio of 2.5 x and a minimum consolidated debt service coverage ratio of 1.1 x. The Amended Credit Facility continues to be secured by substantially all of the assets of the partnership. The Amended Credit Facility removes the prior quarterly distribution restriction of $ 0.12 per outstanding unit and allows for the distribution of all distributable cash flow and cash on hand subject to covenant compliance.

Basis Of Presentation, Description Of Business And Summary Of Significant Accounting Policies [Abstract]
Consolidated Financial Statements	Consolidated Financial Statements The consolidated financial statements include the company’s accounts and all significant intercompany balances and transactions are eliminated. Unconsolidated entities are included in the financial statements on an equity basis. The company owns a 48.9 % limited partner interest and a 2.0 % general partner interest in Green Plains Partners LP. Public investors own the remaining 49.1 % limited partner interest in the partnership. The company determined that the limited partners in the partnership with equity at risk lack the power, through voting rights or similar rights, to direct the activities that most significantly impact the partnership’s economic performance; therefore, the partnership is considered a variable interest entity. The company, through its ownership of the general partner interest in the partnership, has the power to direct the activities that most significantly affect economic performance and is obligated to absorb losses and has the right to receive benefits that could be significant to the partnership. Therefore, the company is considered the primary beneficiary and consolidates the partnership in the company’s financial statements. The assets of the partnership cannot be used by the company for general corporate purposes. The partnership’s consolidated total assets as of June 30, 2021 and December 31, 2020, excluding intercompany balances, are $ 92.4 million and $ 91.2 million, respectively, and primarily consist of property and equipment, operating lease right-of-use assets and goodwill. The partnership’s consolidated total liabilities as of June 30, 2021 and December 31, 2020, excluding intercompany balances, are $ 105.4 million and $ 151.2 million, respectively, which primarily consist of long-term debt as discussed in Note 8 – Debt and operating lease liabilities. The liabilities recognized as a result of consolidating the partnership do not represent additional claims on our general assets. The company also owns a majority interest in BioProcess Algae, a joint venture formed in 2008 as well as a majority interest in Fluid Quip Technologies, LLC with their results being consolidated in our consolidated financial statements. The accompanying unaudited consolidated financial statements are prepared in accordance with GAAP for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Because they do not include all of the information and notes required by GAAP, the consolidated financial statements should be read in conjunction with the company’s annual report on Form 10-K for the year ended December 31, 2020, filed with the SEC on February 16, 2021. The unaudited financial information reflects adjustments, which are, in the opinion of management, necessary for a fair presentation of results of operations, financial position and cash flows for the periods presented. The adjustments are normal and recurring in nature, unless otherwise noted. Interim period results are not necessarily indicative of the results to be expected for the entire year.
Reclassifications	Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation. These reclassifications did not affect total revenues, costs and expenses or net income. See Note 8 – Debt and Note 11 – Stockholders’ Equity for further details.
Revision Of Previously Issued Financial Statements	Revision of Previously Issued Financial Statements During the third quarter of 2020, the company reported an overstatement of both revenues and cost of goods sold by approximately $ 30.0 million within the agribusiness and energy services segment as previously reported for the three and six months ended June 30, 2020. Revenues and cost of goods sold for the three and six months ended June 30, 2020 have been revised to reflect these amounts.
Use of Estimates in the Preparation of Consolidated Financial Statements	Use of Estimates in the Preparation of Consolidated Financial Statements The preparation of consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. The company bases its estimates on historical experience and assumptions it believes are proper and reasonable under the circumstances and regularly evaluates the appropriateness of its estimates and assumptions. Actual results could differ from those estimates. Key accounting policies, including but not limited to those relating to revenue recognition, carrying value of intangible assets, operating leases, impairment of long-lived assets and goodwill, derivative financial instruments, accounting for income taxes and assets acquired and liabilities assumed in acquisitions, are impacted significantly by judgments, assumptions and estimates used in the preparation of the consolidated financial statements.
Description of Business	Description of Business The company operates within four business segments: (1) ethanol production, which includes the production of ethanol, including industrial-grade alcohol, distillers grains, Ultra-High Protein and corn oil, (2) agribusiness and energy services, which includes grain handling and storage, commodity marketing and merchant trading for company-produced and third-party ethanol, distillers grains, corn oil, natural gas and other commodities, (3) food and ingredients, which includes food-grade corn oil and (4) partnership, which includes fuel storage and transportation services. The food and ingredients segment had no activity during the three and six months ended June 30, 2021 and 2020.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents includes bank deposits as well as short-term, highly liquid investments with original maturities of three months or less.
Restricted Cash	Restricted Cash The company has restricted cash, which can only be used for funding letters of credit, for payment towards a revolving credit agreement, or for capital expenditures as specified in certain credit facility agreements. Restricted cash also includes cash margins and securities pledged to commodity exchange clearinghouses and at times, funds in escrow related to acquisition and disposition activities. To the degree these segregated balances are cash and cash equivalents, they are considered restricted cash on the consolidated balance sheets.
Revenue Recognition	Revenue Recognition The company recognizes revenue when obligations under the terms of a contract with a customer are satisfied. Generally, this occurs with the transfer of control of products or services. Revenue is measured as the amount of consideration expected to be received in exchange for transferring goods or providing services. Sales, value add, and other taxes the company collects concurrent with revenue-producing activities are excluded from revenue. Sales of ethanol, distillers grains, corn oil, natural gas and other commodities by the company’s marketing business are recognized when obligations under the terms of a contract with a customer are satisfied. Generally, this occurs with the transfer of control of products or services. Revenues related to marketing for third parties are presented on a gross basis as the company controls the product prior to the sale to the end customer, takes title of the product and has inventory risk. Unearned revenue is recorded for goods in transit when the company has received payment but control has not yet been transferred to the customer. Revenues for receiving, storing, transferring and transporting ethanol and other fuels are recognized when the product is delivered to the customer. The company routinely enters into physical-delivery energy commodity purchase and sale agreements. At times, the company settles these transactions by transferring its obligations to other counterparties rather than delivering the physical commodity. Energy trading transactions are reported net as a component of revenue. Revenues include net gains or losses from derivatives related to products sold while cost of goods sold includes net gains or losses from derivatives related to commodities purchased. Revenues also include realized gains and losses on related derivative financial instruments and reclassifications of realized gains and losses on cash flow hedges from accumulated other comprehensive income or loss. Sales of products, including agricultural commodities, are recognized when control of the product is transferred to the customer, which depends on the agreed upon shipment or delivery terms. Revenues related to grain merchandising are presented gross and include shipping and handling, which is also a component of cost of goods sold. Revenues from grain storage are recognized over time as the services are rendered. Revenues related to the design, engineering and installation of equipment are recognized over the term of the related contracts as equipment is delivered and installed and services are performed. A substantial portion of the partnership revenues are derived from fixed-fee commercial agreements for storage, terminal or transportation services. The partnership recognizes revenue upon transfer of control of product from its storage tanks and fuel terminals, when railcar volumetric capacity is provided, and as truck transportation services are performed. To the extent shortfalls associated with minimum volume commitments in the previous four quarters continue to exist, volumes in excess of the minimum volume commitment are applied to those shortfalls. Remaining excess volumes generating operating lease revenue are recognized as incurred.
Shipping and Handling Costs	Shipping and Handling Costs The company accounts for shipping and handling activities related to contracts with customers as costs to fulfill its promise to transfer the associated products. Accordingly, the company records customer payments associated with shipping and handling costs as a component of revenue, and classifies such costs as a component of cost of goods sold.
Cost of Goods Sold	Cost of Goods Sold Cost of goods sold includes direct labor, materials, shipping and plant overhead costs. Direct labor includes all compensation and related benefits of non-management personnel involved in ethanol production. Grain purchasing and receiving costs, excluding labor costs for grain buyers and scale operators, are also included in cost of goods sold. Materials include the cost of corn feedstock, denaturant, and process chemicals. Corn feedstock costs include gains and losses on related derivative financial instruments not designated as cash flow hedges, inbound freight charges, inspection costs and transfer costs, as well as reclassifications of gains and losses on cash flow hedges from accumulated other comprehensive income or loss. Plant overhead consists primarily of plant utilities, repairs and maintenance and outbound freight charges. Shipping costs incurred by the company, including railcar costs, are also reflected in cost of goods sold. The company uses exchange-traded futures and options contracts and forward purchase and sale contracts to attempt to minimize the effect of price changes on ethanol, grain and natural gas. Exchange-traded futures and options contracts are valued at quoted market prices and settled predominantly in cash. The company is exposed to loss when counterparties default on forward purchase and sale contracts. Grain inventories held for sale and forward purchase and sale contracts are valued at market prices when available or other market quotes adjusted for basis differences, primarily in transportation, between the exchange-traded market and local market where the terms of the contract is based. Changes in forward purchase contracts and exchange-traded futures and options contracts are recognized as a component of cost of goods sold.
Operations and Maintenance Expenses	Operations and Maintenance Expenses In the partnership segment, transportation expenses represent the primary component of operations and maintenance expenses. Transportation expenses include railcar leases, freight and shipping of the company’s ethanol and co-products, as well as costs incurred storing ethanol at destination terminals.
Derivative Financial Instruments	Derivative Financial Instruments The company uses various derivative financial instruments, including exchange-traded futures and exchange-traded and over-the-counter options contracts, to attempt to minimize risk and the effect of commodity price changes including but not limited to, corn, ethanol, natural gas, soybean meal and soybean oil. The company monitors and manages this exposure as part of its overall risk management policy to reduce the adverse effect market volatility may have on its operating results. The company may hedge these commodities as one way to mitigate risk; however, there may be situations when these hedging activities themselves result in losses. By using derivatives to hedge exposures to changes in commodity prices, the company is exposed to credit and market risk. The company’s exposure to credit risk includes the counterparty’s failure to fulfill its performance obligations under the terms of the derivative contract. The company minimizes its credit risk by entering into transactions with high quality counterparties, limiting the amount of financial exposure it has with each counterparty and monitoring their financial condition. Market risk is the risk that the value of the financial instrument might be adversely affected by a change in commodity prices or interest rates. The company manages market risk by incorporating parameters to monitor exposure within its risk management strategy, which limits the types of derivative instruments and strategies the company can use and the degree of market risk it can take using derivative instruments. The company evaluates its physical delivery contracts to determine if they qualify for normal purchase or sale exemptions which are expected to be used or sold over a reasonable period in the normal course of business. Contracts that do not meet the normal purchase or sale criteria are recorded at fair value. Changes in fair value are recorded in operating income unless the contracts qualify for, and the company elects, cash flow hedge accounting treatment. Certain qualifying derivatives related to ethanol production and agribusiness and energy services are designated as cash flow hedges. The company evaluates the derivative instrument to ascertain its effectiveness prior to entering into cash flow hedges. Unrealized gains and losses are reflected in accumulated other comprehensive income or loss until the gain or loss from the underlying hedged transaction is realized and the physical transaction is completed. When it becomes probable a forecasted transaction will not occur, the cash flow hedge treatment is discontinued, which affects earnings. These derivative financial instruments are recognized in current assets or current liabilities at fair value. At times, the company hedges its exposure to changes in inventory values and designates qualifying derivatives as fair value hedges. The carrying amount of the hedged inventory is adjusted in the current period for changes in fair value. Estimated fair values carried at market are based on exchange-quoted prices, adjusted as appropriate for regional location basis values, which represent differences in local markets, including transportation as well as quality or grade differences. Basis values are generally determined using inputs from broker quotations or other market transactions. However, a portion of the value may be derived using unobservable inputs. Ineffectiveness of the hedges is recognized in the current period to the extent the change in fair value of the inventory is not offset by the change in fair value of the derivative.
Recent Accounting Pronouncements	Recent Accounting Pronouncements On January 1, 2021, the company early adopted the amended guidance in ASC 470-20 , Debt - Debt with Conversion and Other Options and ASC 815-40 , Derivatives and Hedging - Contracts in Entity’s Own Equity - Accounting for Convertible Instruments and Contracts in an Equity’s Own Equity. The adoption of this guidance resulted in a $ 49.5 million decrease in additional paid-in capital, an $ 11.4 million increase in retained earnings and a $ 38.1 million increase in long-term debt, which included a $ 39.4 million increase in debt principal offset by a $ 1.3 million increase in debt issuance costs, resulting from amounts previously bifurcated to equity being reclassified to debt. See Note 8 – Debt and Note 11 – Stockholders’ Equity for further details. In March 2020, the FASB issued amended guidance in ASC 848, Reference Rate Reform - Facilitation of the Effects of Reference Rate Reform on Financial Reporting, and a subsequent update in January 2021, which provides optional expedients and exceptions to U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burden related to the expected market transition from the LIBOR and other interbank offered rates to alternative reference rates. The expedients and exceptions provided by the amended guidance do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The guidance is effective upon issuance and to be applied prospectively from any date beginning March 12, 2020 through December 31, 2022. The amended guidance is not expected to have a material impact on the company’s consolidated financial statements. In December 2019, the FASB issued amended guidance in ASC 740, Income Taxes - Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 74 0. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of ASC 740 by clarifying and amending existing guidance. The amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption of the amendments is permitted. The company is evaluating the impact of this standard on its consolidated financial statements.
