topics. • We continue taking steps to ensure CHS has a Board of Directors that can lead the company into the future with vision and commitment to the cooperative system. o Incorporating a nominating committee into CHS governance is one element of that work, giving more structure and transparency to our election process. o The Director elections at this year’s annual meeting will be your first opportunity to vote for candidates that have been assessed and recommended by the nominating committee. o If you know someone who would make an excellent nominating committee member or CHS Director – or if you are interested in those leadership opportunities – please talk with a Board member from your region. 5

© 2026 CHS Inc Public© 2026 CHS Inc Public Business overview Jay Debertin, president and CEO Welcome • Looking forward to connecting through virtual format. • Later our business leaders will come on for a panel, but first I want to give you some of my thoughts on the year and the state of CHS. State of CHS and ag/energy markets • Olivia will speak to the financial impact, but a few thoughts from me on our ag and energy commodity markets. • Energy oSeeing stronger performance and good margins oBut also high costs to operate (RINs) • Grains o Those same policies that create high costs in energy, create opportunity in processing and we’re seeing good margins in oilseed processing 7

oStill see high inventories on grain, strong competition – continue to advocate for year-round E15 as one way to increase domestic demand for corn-based ethanol • Agronomy oHigh prices and changing purchasing decisions What CHS is doing to remain strong – for you • Portfolio review – you may be aware of a few facility closures or sales. We’re focused on making sure every asset is working for us and providing the most value. • At the same time, future investments – we are looking at opportunities within our core capabilities, particularly in areas that reflect what U.S. agriculture is going to need. oAgronomy – more supply certainty among trade and geopolitical uncertainty oProcessing – more domestic consumption of U.S. grain and growth in biofuels oSpeed and space – continued investment in local ag supply chains • Internationally, continuing to diversify origination in order to stay nimble and to continue to supply customers with grain year-round. oCompleted Danube expansion oSantos breaking ground soon oHowever, international investments continues to be a small portion of our CapEx. Transition to Olivia • Now, I’d like turn it over to Olivia for our financial report for the first three quarters of our fiscal year • I’ll be back on for the business panel 7

© 2026 CHS Inc Public© 2026 CHS Inc Public Financial report Olivia Nelligan, CFO, chief strategy officer Thank you for joining us today, and thank you for your business and support of CHS. Today I will share highlights from our financial performance for the first three quarters of fiscal year 2026 through 31 May 2026. 8

This structure reflects how we operate and gives us a clear view of end-to-end profitability, from the farmgate to customers around the world. With that in mind, let’s look at our year-to-date financial performance. 9

While modestly below last year, this is a strong result in light of dynamic market conditions including lower grain prices, compressed margins, shifting global trade flows, regulatory impacts and geopolitical uncertainty. It is also reflective of shifting biofuels policy, as Jay mentioned. 10

• On the grain and processing side, stronger biofuels policy supports demand for feedstocks such as soybean oil. That demand strengthens crush margins and creates opportunities for our oilseed processing business. • At the same time, those same policies increase costs within our refined fuels business through renewable fuel credit obligations, commonly known as RINs. These obligations significantly increase our refinery operating costs and negatively impact our earnings. So while biofuels policy creates a tailwind for grains and processing, it has created a headwind for energy and it is a good example of why our diversified and integrated portfolio makes us a more resilient company. With that backdrop in mind, I will provide a few more specifics on each segment. 10

As we carry out our contracts, there is the potential to see losses reverse and improve earnings in future periods. 11

As we execute contracts, we may see a reversal of these impacts with the potential to see some 12

improvement to earnings in future quarters. These types of contract-related accounting differences are typical every year, but they can have a more outsized impact on our earnings when markets are highly volatile like they are today. 12

However, this was partially offset by lower crop nutrients and crop protection volumes as producers made cautious purchasing decisions amid tight farm margins. 13

We also are proud that we have maintained a strong balance sheet and excellent liquidity throughout the year. Looking ahead, we expect continued commodity volatility due to geopolitical and potential weather impacts. We are expecting a continued environment of policy uncertainty and pressure on the farm economy. 16

Our focus remains on operating efficiently, managing costs, aligning assets with our product-line strategies and investing where we can win and where we can add value for our owners. We are confident in the strength of CHS and our diversified portfolio. We will continue working every day to serve our customers and create value for you. Thank you again for your continued business and your commitment to CHS. Now, I will pass it back to Jay and our panelists. 16
