Margin Decline The Result of Higher Feedstock Costs We Anticipate Feedstock Costs Will Decline In 2019 and 2020 9 VTNR “Clean - Dirty” Spread Cost Inputs / Product Pricing > We purchase UMO (e.g. feedstock) at a discount to 3% high sulfur fuel oil (HSFO); we price our finished product versus to NY Harbor Ultra Low Sulfur Diesel Fuel (ULSD) > The “spread” between the UMO cost and our finished product price is our gross margin per gallon sold > IMO 2020 is expected to reduce the value of 3% HSFO; as 3% HSFO oil costs decline, so will UMO (feedstock) costs > Even as our feedstock costs decline, we project that benchmark diesel prices for low sulfur marine fuel will rise materially leading up to IMO 2020 Implies Spread Between 3% HSFO and ULSD NYMEX $/ bbl Higher 3% HSFO Costs Temporarily Impacted Distillate Margin Capture $0.00 $5.00 $10.00 $15.00 $20.00 $25.00 $30.00 $35.00
