Introduction---Executive Summary MLP Market Backdrop MLPs across all sectors continue to struggle to attract new public investors and have experienced negative fund flows, resulting in very limited access to equity capital Small, low float MLPs have been more negatively impacted given lack of scale, trading liquidity and poor institutional interest Even in the context of solid underlying business fundamentals and reasonably high payout ratios, MLPs broadly have experienced increasingly high distribution yields. Consequently, several sponsors have opted to execute simplification transactions or take their partnerships private There have been 34 MLP take privates since the beginning of 2018, with 13(1) affiliated MLPs currently remaining, all likely to be bought in or restructured in the near term BofA believes a take private of GPP may be the best path forward for GPRE for the following key reasons: GPP is an expensive source of capital – With its 13.9% distribution yield, GPP no longer serves the MLP’s original purpose of providing a low cost source of capital GPP does not provide access to capital and likely will not in the future – There is no clear catalyst to restore access to MLP capital markets as investor sentiment has permanently shifted away from the MLP model. Additionally, GPP will struggle to attract MLP investors with its 30-day average daily trading value of $0.44MM(2) de minimis trading activity, and lack of research analyst coverage Opportunity to retain cash flows – GPP costs GPRE ~$20MM of cash flow per year through distributions to public unitholders plus public company costs, which could otherwise be reinvested into the business Opportunity to simplify structure – A take private allows GPRE to reduce management burden, simplify organizational structure, eliminate public company expenses and increase flexibility to execute desired strategy BofA recommends exploring option to simplify the corporate structure, retain full control and optimize free cash flow 1 MPLX PBFX DKL CQP WES HESM NBLX RTLR CNXM OMP Sources: RTLR Dist.

Introduction---Executive Summary (Cont’d) Process Considerations If GPRE makes an offer to GPP, GPP will likely form a conflicts committee of independent directors which, with the advice of its financial and legal advisors, will negotiate the terms of the transaction on behalf of the unaffiliated unitholders Negotiations in precedent transactions have typically lasted from a few weeks to several months Unitholder consent will be required; however, since GPRE nearly controls a majority of the common units of GPP (0.2% needed), there is a high likelihood that the requisite approval will be obtained An initial proposal at a 0% premium to current trading levels would be consistent with recent precedent MLP buy-in proposals Subject to any unforeseen market or macro disruption and/or moves following announcement of an initial offer, precedent transactions would imply that the final negotiated premium would likely be in the low to high-teens range BofA recommends exploring option to simplify the corporate structure, retain full control and optimize free cash flow 2 1 Executive Summary (Cont’d) Introduction

Introduction---Overview 3 Overview GPP GPRE Simplifies corporate structure and governance and expands investment appeal to a broader range of corporate investors Increases cash flow retention by eliminating GPP distributions to public Reduces public company costs Increases debt capacity at GPRE Improves cost of capital at GPRE Near-term benefit from tax basis step-up Exchanges units for a more liquid security in the form of GPRE stock GPP unitholders able to participate in growth potential of GPRE 2.0 Unitholders may receive a premium; whereas sales in the open market will likely create downward pressure Efficient monetization of unitholders’ interests without being exposed to downside and suffering from poor trading liquidity Introduction A take private of GPP could be the best alternative for all stakeholders

Introduction 6 Introduction Overview of Key Considerations Requires evaluation of the merits and considerations of a public versus private approach to GPP Board Acquirers often prefer the public approach as it substantially increases the chances of two securities trading at a tight exchange ratio band; a public approach also ensures that negotiations stay on track. A private approach is often preferred if the two securities have traded at a consistent exchange ratio, and there is high conviction that a private negotiation will lead to a constructive outcome If a private approach is made, GPP’s Conflicts Committee may still elect to disclose the offer publicly Of the 10 most recent MLP take privates, 7 have used a public approach However, GPRE will be required to update its 13D which will signal a potential transaction to the market even without a formal public announcement – Thus a truly private approach may not be feasible in this situation Given the need to file an amended 13D, GPP may decide to issue a press release upon receipt of the offer Approach Dynamics Conflicts Committee Process Requires evaluation of the merits and considerations of negotiating a merger (substantially more common) or executing a tender offer Even with a tender offer, legal advisors will likely suggest seeking Conflicts Committee approval Execution Method Description Consideration If GPRE were to make an offer to the GPP board to purchase the GPP public units, GPP’s Board would form a Conflicts Committee to review the transaction on behalf of unaffiliated unitholders Conflicts Committee will hire independent financial and legal advisors Roll Out Plan The overall process timeline can range from 3-6 months depending on the execution strategy and length of negotiations with the Conflicts Committee Timeline Per the GPP partnership agreement, a take private can be consummated by a Unit Majority (i.e., a majority of the common units outstanding) The Conflicts Committee may try to negotiate for a “majority of the minority” vote, which would require the approval of a majority of common units by written consent held by unitholders unaffiliated with GPRE – such a requirement is extremely uncommon and GPRE should resist Effective communication of the merits of a transaction can be important to help shape the SIRE market reception Precedent transactions have used a variety of methods to present the transaction to the market including press releases, investor presentations and conference calls Voting Dynamics The following discusses how best to execute a take private of GPP Precedent Transactions While third-party M&A transactions typically require a control premium, affiliate take private transactions where a small minority exits the investment typically require lower premiums; since 2015 mean and median premiums of MLP take private transactions have been 13.4% and 11.2%, respectively

5. Flowback Considerations 5. Flowback Considerations

Flowback Considerations---Flowback Considerations for GPRE 21 Our analysis suggests that, if GPRE were to make a share-based buy-in offer for GPP, we expect flowback to be modest as there is not much shareholder overlap between the two companies The flowback may be from index and active funds with MLP, Midstream and / or infrastructure based mandates Some of these institutions may still be able to hold GPRE stock in other energy sector funds Long only funds will be strategic when exiting and won’t “flood the market” The targeting of incremental buyers will be pivotal to building a long term supportive shareholder base should existing GPP shareholders choose to sell, and demand could be absorbed to an extent by: Existing GPRE shareholders, especially those underweight GPRE vs. peers / S&P 600 Holders of both GPRE and GPP with conviction in the pro forma equity story Merger Arbitrage Investors Selling typically begins immediately following an announcement Active funds that cannot own securities outside of MLP / midstream / infrastructure mandates tend to have more discretion on timing of sales; these investors will make sales before and after the closing of a transaction Merger arbitrage investors will be active upon announcement and typically can represent c.15-20% of a target’s issued share capital Selling pressure is typically concentrated immediately post-announcement and around completion of the transaction Key Takeaways for GPRE Flowback Considerations for GPRE Flowback Considerations

Flowback Considerations---Shareholder Crossover – GPRE & GPP 22 Flowback Considerations GPP Top 20 Active Institutional Shareholders GPRE Top 20 Active Institutional Shareholders Holder of both GPRE and GPP ____________________ Source: Factset as of April 21, 2023 per most recent 13-F filings dated December 30, 2022. Excludes index funds and broker / dealers. While a portion of GPP’s top 20 active holders also have a position in GPRE, indicating they will likely retain a position in the pro forma company, these investors represent only ~1% of total U/O. None of GPRE’s top 20 holders have a top 20 holding in GPP, signaling the risk of active money to churn post-announcement, although these funds could well choose to retain their shares Shareholder Crossover – GPRE & GPP

Many analysts (Jefferies, Craig Hallum, Oppenheimer included) attributed the Q1 2023 miss to volatile ethanol markets, weaker crush margins, and increasing feedstock prices Analysts perceive GPRE as being on track with its transition to GPRE 2.0, as judged by key metrics such as rising run-rate Ultra-High Protein production, full production at existing 5 facilities, and heightened yields (on track for 4.0 lb UHP / bushel vs expected 3.5 lb) The biggest point of concern among research analysts is the projected UHP pricing premium, as, while still a significant value add (~$60 million EBITDA in 2022), it appears to be coming in below management’s expected J-Curve Research analysts project that beginning in 2025, GPRE’s partnership with Summit Carbon Solutions will contribute $50 – $100 million in EBITDA uplift due to a lower CI score with the possibility for further increases from IRA clarification Research analysts expect GPRE 2.0 to be rewarded by the diversity and transparency of its various business operations, and believe they are all viable opportunities to transition away from strict reliance on ethanol Wall Street Research Commentary Regarding Green Plains 2.0 Green Plains Inc. Situation Analysis Analyst Commentary While pointing to a more favorable ethanol crush margin backdrop, we reiterate our view that GPRE is on the precipice of delivering its biorefinery transformation vision. With our first look at UHP sales volumes, we are encouraged by production rates … Looking across each of its growth pillars (protein, oil, sugar, carbon), GPRE has multiple ways to win, however we see only one or two as needed to drive sustained positive EBITDA, and reduced earnings volatility. - Oppenheimer (May 2023) The company continues to make good progress on its 60% protein content product (for aquafeed), which comes with significantly higher premium. Sales towards that market could start in earnest by 4Q22 and grow from there. Additionally, we believe that pricing for recurring business is likely to increase as customers are satisfied with the results of their first order. - BofA Securities (May 2023) The good news is this [GPRE 2.0] plan continues to show tangible progress with full production of High Proteins reached at five plants with strong commercial demand, increased yields for renewable corn oil, Clean Sugars progressing towards the start-up of production at its Shenandoah, IA plant in early 2024, and the overall Carbon Capture opportunity becoming clearer. In addition, GPRE announced its offer to acquire Green Plains Partners (GPP) which would simplify its organization structure, reduce OpEx, and be accretive to cash flow. - Craig-Hallum (May 2023) 41 Source: Wall Street Research

Many analysts (Jefferies, Craig Hallum, Oppenheimer included) attributed the Q1 2023 miss to volatile ethanol markets, weaker crush margins, and increasing feedstock prices Analysts perceive GPRE as being on track with its transition to GPRE 2.0, as judged by key metrics such as rising run-rate Ultra-High Protein production, full production at existing 5 facilities, and heightened yields (on track for 4.0 lb UHP / bushel vs expected 3.5 lb) The biggest point of concern among research analysts is the projected UHP pricing premium, as, while still a significant value add (~$60 million EBITDA in 2022), it appears to be coming in below management’s expected J-Curve Research analysts project that beginning in 2025, GPRE’s partnership with Summit Carbon Solutions will contribute $50 – $100 million in EBITDA uplift due to a lower CI score with the possibility for further increases from IRA clarification Research analysts expect GPRE 2.0 to be rewarded by the diversity and transparency of its various business operations, and believe they are all viable opportunities to transition away from strict reliance on ethanol Wall Street Research Commentary Regarding Green Plains 2.0 Green Plains Inc. Situation Analysis Analyst Commentary While pointing to a more favorable ethanol crush margin backdrop, we reiterate our view that GPRE is on the precipice of delivering its biorefinery transformation vision. With our first look at UHP sales volumes, we are encouraged by production rates … Looking across each of its growth pillars (protein, oil, sugar, carbon), GPRE has multiple ways to win, however we see only one or two as needed to drive sustained positive EBITDA, and reduced earnings volatility. - Oppenheimer (May 2023) The company continues to make good progress on its 60% protein content product (for aquafeed), which comes with significantly higher premium. Sales towards that market could start in earnest by 4Q22 and grow from there. Additionally, we believe that pricing for recurring business is likely to increase as customers are satisfied with the results of their first order. - BofA Securities (May 2023) The good news is this [GPRE 2.0] plan continues to show tangible progress with full production of High Proteins reached at five plants with strong commercial demand, increased yields for renewable corn oil, Clean Sugars progressing towards the start-up of production at its Shenandoah, IA plant in early 2024, and the overall Carbon Capture opportunity becoming clearer. In addition, GPRE announced its offer to acquire Green Plains Partners (GPP) which would simplify its organization structure, reduce OpEx, and be accretive to cash flow. - Craig-Hallum (May 2023) Source: Wall Street Research 42
