 Marketing/Merchandising   Kristan Barta – Commercial Manager  

 This crop year has had it’s fair share of challeges      

 SIRE CORN 2019    Grind = ~45 Million BushelsEnogen – 10%We offer several attractive marketing strategies: Flat price, Deferred pricing, Basis contracts, HTA’s, Alliance Advantage, and On Farm Pick-Up.  

 SIRE CORN 2019    With 176 bushel per acre yields and 1.73 billion bushels carry out, we expect to see a very historical basis with small volatility – beyond weather or logistic events We are anticipating producers carrying length into the summer months - similar to last year 

 SIRE Basis history 

  November 2017 GRAIN RECEIVINGPit Automation  

 SIRE CORN 2019    Last year, we installed a state of the art pit automation system. This allows us the flexibility and efficiency to utilize both pits for Yellow Corn and Enogen – while being fully automated. We have been able to extend Enogen hours, and dump trucks in less than 8 minutes from scale to scale. This has also allowed our employees to more efficiently distribute their time in performance of tasks for plant operations. 

 Grain Receiving monitor  

 SIRE DIStillers grain    SIRE produced 406,000 tons of distillers grains in Fiscal 2018.Exports important to the distillers program. Last year SIRE exported 120,000 tons of DDG by truck and rail.Southeast Asia has become a large user in recent years, keeping the market trading at averages over 100% VTC. Currently shipping 3,000 tons of Wet distillers grain weekly within a 90 mile radius of the plant.

 SIRE STRENGTHS    We strive to provide a quick unload, helpful service, and a competitive market place for our producers!! 

 Industry Update   Mike Jerke – CEO/President  

 Back to the future… 

 Low Carbon Fuel Standard (LCFS)   California first enacted in 2007 and began implementing in 2011.Goal is to reduce the carbon intensity of fuels over time.All fuel manufacturers are assessed a carbon index (CI) score for the fuel they produce.Ethanol plays significant role in achieving the goals set by California.Plant location, source of energy, and efficiency of process are some of the factors that impact an individual plants CI score.Credit trading system in place to incentivize lower CI gallons.  

 LCFS – Concept is gaining traction beyond California.  CanadaOregonNortheastern United StatesEuropeMidwest United States (recent dialog) 

 Thoughts on the future… (how to improve the three levers discussed earlier)  Core competency is ethanol production along with its associated co-products.Continue to generate value through efficient ethanol production.Evaluation of plant enhancement projects with focus on ROI and increasing efficiency.Revenue diversification. 

   Lucy Norton, Managing Director 

 Professionalism – organized, thoughtful, no short cuts.Focused – relentless, dogged determination.Team-centric – all pulling in the same direction to the common goal.Tie it all together with very good…Communication – Clear and concise   From a personnel perspective, three characteristics (at least) that drive success 

 People, assets, and culture….  …and keeping the safety and well being of each top of mind.
