4 We Have Also Been Optimizing Our Business to Maximize Our Internally Generated Cash Flows Last year, we kicked off an initiative to optimize our spending across our business to: Scrutinize every dollar of OPEX and G&A expenses, with the goal of making meaningful strides in our cost structure to maximize internally generated cash flows High-grade every dollar of our strategic spending to ensure that we only execute projects that meet or beat our internal hurdles and are lean, efficient and effective We successfully identified ~$100 million in cost and spending reductions, across 2022 and 2023 We are continuing to optimize our spending to increase our free cash flow in 2023 2022 Optimization Initiative Results: ~$100MM Aggregate 2022 and 2023 cost and spending reductions
5 And We Have Redeemed the Remaining 1/3 Series D Preferred Units While Continuing to Maintain a Healthy Debt-to-EBITDA Ratio In mid-August, we issued 14.95 million common units for net proceeds of $223 million (including exercise of overallotment option) to complete our redemption of the Series D The equity offering is immediately accretive to cash flows through cost savings on distributions The offering is also slightly accretive to our leverage metric, and we continue to target a healthy debt-to-EBITDA ratio of below 4.0x by year-end 2023 Redeeming the remaining Series D eliminates an obligation senior to our common unitholders, simplifies our capital structure and increases our financial resilience and flexibility We redeemed the remaining one-third of Series D Preferred Units on September 12th, which represents an expedited timeline compared to our previously announced target of YE 2024 Over 12 months ahead of original plan

11 Ammonia is a Critical Chemical for the World’s Food Supply, and a Key Component of DEF, Which Reduces Harmful Emissions Ammonia is the basic building block for all types of nitrogen fertilizer which is an essential nutrient for growing plants About 80% of the 200 million tons of ammonia produced each year is used for fertilizer About 50% of the world’s food production depends on ammonia Ammonia is also used to make urea, a critical component of Diesel Exhaust Fluid (“DEF”) DEF converts the nitrous oxide (NOx) emitted by diesel engines into water and nitrogen Virtually all diesel engines, from those powering light-duty vehicles to heavy-duty truck to industrial machinery operate, require DEF to comply with tightening emissions standards, in the U.S. and also in nations around the world Global DEF demand is expected to continue to grow by an expected ~20% from 2023 to 2026 d 50% of World’s Foo Production Depends on NH3 Renewable Fuels Global Demand for DEF Expected to Grow From 2023 to 2026 by ~20% Sources: Science Magazine, IHS Markit, Argus, Research & Markets Global Ammonia Report
12 Ammonia, the World’s Second-most Widely Used Chemical, Offers Significant “Greening” Opportunities Traditional fossil-fuel ammonia production is estimated to contribute about 1.6% of global GHG emissions, which has driven interest in its de-carbonization “Blue” ammonia is produced with natural gas, but the associated emissions are captured and stored “Green” ammonia is produced using “renewable” electricity to power an electrolyser to extract hydrogen from water and an air separation unit to extract nitrogen from air, which are then combined, through a chemical reaction powered by renewable electricity, to produce ammonia In addition, “blue” and “green” ammonia have potential for use as lower-carbon alternative fuels: for engines/turbines to generate electricity, in alkaline fuel cells, as an up-to-70% blend ICE vehicles and for the maritime industry Ammonia can also be a lower-cost option for transporting hydrogen, which can be used for fuel cells or other applications. Ammonia is easier to transport and store than hydrogen, as it doesn’t require cryogenic or high- pressure storage and can be relatively easily cracked to convert it to hydrogen NH3 Gas Turbine NH3 Fuel-cell Ship 70% NH3-fueled Car Sources: Science Magazine, IHS Markit, Argus, Research & Markets Global Ammonia Report Renewable Fuels Gray Ammonia Blue Ammonia Green Ammonia Derived from natural gas, nearly all of the world’s production made utilizing the Haber-Bosch process Gray Ammonia for which by-product CO2 has been captured and stored, reducing climate impact Produced with hydrogen from water electrolysis powered by renewable energy
13 Our Ammonia System spans approximately 2,000 miles from Louisiana north along the Mississippi to Missouri, and then Northwest and East, to Nebraska and Indiana Today, we provide the lowest-cost option for transporting both imported and domestically produced ammonia to fertilize crops in our nation’s “breadbasket” We have capacity available to transport additional volumes, including “blue” or “green” ammonia Currently running ~30 MBPD (~3,500 STPD1), but have operating capacity close to ~50 MBPD (~5,500 STPD) Our Ammonia System currently represents 5-10% of our pipeline segment revenues We expect the system’s utilization, and its revenue contribution, to see strong growth, starting in early 2024 We have near-term opportunities for low capex projects that we expect to meaningfully increase our system utilization, and we are discussing larger, longer-term ammonia opportunities for our system, as well as for our St. James facility Our Ammonia System has Capacity to Expand Our Utilization 1 – short tons per day Renewable Fuels Third-party terminal NuStar Energy L.P.

14 We have partnered with OCI Global (OCI) to build a new 14-mile pipeline segment that will connect OCI’s facility in Wever, IA to our existing ammonia pipeline OCI’s facility uses ammonia to make fertilizer and to meet growing demand for DEF (Diesel Exhaust Fluid) We have agreed to provide transportation services under a long- term contract Healthy-return, low-capital project will increase utilization Expected completion in early 2024 OCI has committed $30 million in capital expenditures for new ammonia cooling and storage infrastructure at their Wever facility and is expected to bring an additional 1.1 million tons of blue ammonia capacity online in 2025 from the Gulf Coast OCI’s facility in Wever, IA Terminal NuStar Energy L.P.
