Thanks, John. Good morning and welcome to Calumet's first quarter 2026 earnings call. The beginning of this year has certainly been an eventful and strategically pivotal period for Calumet. Late in the quarter, we saw the renewable fuels market take a major step forward following EPA's long-awaited Set 2 RVO announcement, and we entered one of the strongest margin environments we've seen across both traditional and renewable energy markets. Further, we brought down Montana Renewables for a turnaround in MaxSAF 150 expansion in early March and successfully commenced operations in early May.
While these developments did not fully benefit first quarter financial results due to previously disclosed downtime at Shreveport and planned expansion work in Montana, Calumet's exceptionally well-positioned to capture these tailwinds, further accelerate deleveraging, and continue our long-term growth and value creation strategy, which we'll discuss further in this call before David takes us through the quarter. Let's turn to slide four and begin with the outlook for our specialties business. First, as we've seen historically, Calumet's integrated business is robust and performs throughout the business cycle and is particularly well-positioned for the current market, with commodity spreads growing sharply due to global disruptions. We make fuels the co-product of our specialty production process. Typically, when cracks are lower, strong and stable specialty margins carry the day. When crack spreads are high, as they are now, we're fully exposed to that upside.
Long term, the Specialty business will take advantage of positive commodity environments to strategically deploy excess cash flow into Specialty's growth. Right now, it creates an accelerated deleveraging opportunity and also opens the door to targeted low-risk, high-return growth opportunities. The recent volatility has also reminded us of the capability of our Specialty's commercial excellence engine. In March, crude oil prices increased over 50% in a two-week period, and it moved further from there. Our commercial team rapidly executed on over 20 price increases across our product lines to counter the cost escalation, and our customers understand the uniqueness of this current environment.
While we have some sales contracts tied to previous month pricing and further downstream in Performance Brands, we see a bit more lag, the fact that our SPS Specialty's business was able to demonstrate $54 a barrel margins this past quarter despite the rapid cost inflation is a testament to the nimbleness of this team. The outlook improves on that with the increases now in. The other pillar of commercial excellence is providing an exceptional customer experience. Despite the craziness in this market, Calumet's team went to great lengths to ensure our customers were as well-serviced as humanly possible in this remarkable time. That didn't come without a bit of short-term financial cost, our Specialty's enterprise is built on delivering a world-class customer experience. Further, let's hit on what's going on in the broader Specialty's market.
We all know that roughly 20% of the world's daily crude oil comes through the Strait of Hormuz by now. What's less publicized is that about 10% of the global base oil supply does as well. Probably more importantly, a disproportionate amount of the world's lube crudes, as we call them, come from the Middle East. These are grades that have particularly good specialty qualities and yields. They're purchased around the world, particularly in Asia. At Calumet, our crude supply is largely domestic and readily available. Further, we always value the fact that we're a fully integrated, fully dedicated producer of Specialty Products, which provides stable and quality control despite the market condition. In strong commodity markets like this one, it also carries an even higher than normal economic benefit.
Non-integrated suppliers purchase intermediates like VGO or fuels like diesel and jet as specialty feedstocks to produce lubes and solvents. We're able to make these end products from crude oil, which means we capture the intermediate value of the distillate and intermediates embedded in the product price. We just completed two successful planned turnarounds at our Cotton Valley and Princeton facilities in April, and we're running at max volumes across the board to capture the current opportunity. Let's turn to slide five. Making nearly as many headlines as the fossil energy market this past quarter was the EPA's Set 2 RVO release in March, which has reset the outlook for the biofuels industry and Montana Renewables. Well, this is spelled like a new market environment given the past two years under the Set 1 Rule.
What we're actually seeing is the EPA applying the same tested and stable dynamic used historically that supports strong, stable margins in this business. Many will remember the error in the 2023 Set 1 ruling was due to the EPA assuming feedstock would not be readily available. With that now corrected, after American farmers proved they'll rise to the challenge and produce the necessary feeds, the EPA resumed applying the methodology it's used for over a decade. In this, they evaluate prior year's biofuel capacity and increase the mandate to incentivize continued utilization growth. We see this dynamic displayed through the three graphics on this slide. Starting on the bottom left-hand of the slide, we're reminded that this industry has seen steady $2 a gallon index margins consistently for years, which is historically what has been required for the industry's biodiesel capacity to run.
When biodiesel was not required during Set 1, this dynamic was broken, and we saw industry utilization at roughly 50%. MRL was able to break even in that environment, which demonstrated our unique position, but we're much more excited about this current market for both our business and the industry. Taking a look at the industry supply stack in a chart on the top right here, we see how efficient this market is as well. Post-ruling, margins have rapidly increased to create an incentive for all biomass-based diesel production to come back online. We also see the Set 2 RVO actually requires the industry to operate at higher than historically demonstrated utilization levels to meet it. Our view is there are three ways that industry can fill this gap. First, the EPA understood there were carry forward RINs available from the small refinery exemptions announced last year.
These carry forwards can satisfy most of the supply and demand gap in 2026, but there aren't nearly enough to settle 2027. Second, imports can fill the gap despite being disadvantaged to domestic biodiesel, given they don't qualify for the PTC. The third is that this policy incentivizes industry to continue its utilization improvement journey. This journey certainly stalled over the past three years, but the administration knows that re-refineries typically run at slightly higher utilization levels, and our industry in its early stages can also continue to improve. Efficiency improvement reduces the cost of biofuels, adds more reliable domestic energy, and incentivizes the growth of more domestic agriculture, all while improving air quality. These results are right down the fairway for the current administration and also be expected to be supported in a bipartisan fashion, as they always have been.
We believe the industry is up for this challenge, and while very high sustained utilization certainly won't happen overnight, especially given the level of damage done over the Set 1 days, it can happen over time. The third chart on this page is a little closer look at historic biomass-based diesel production levels in relation to the RVO on a monthly basis. The difference in production and demand call results in a build or draw on the RIN bank. Again, we see how rapidly industry utilization plummeted during Set 1, and we also see how it's increased with today's more promising future, albeit with a long way to go to meet the Set 2 levels. In addition to a renewed outlook for renewable diesel, we also just commenced operations post our MaxSAF 150 expansion, which was a major step for Montana Renewables.
Let's turn to slide six and further discuss this step and SAF's role in domestic energy growth. We've often discussed the promise of SAF and Montana Renewables' ability to capture the SAF premium, given its first-mover marketing experience. Now that we've started up our plant post the expansion, we turn our focus to producing increased SAF volumes. Through the initial operating period, we'll continue to condition the catalyst, complete a performance validation, and deliberately and steadily ramp production to ensure consistent product quality for our existing customers and for our new customers to integrate into their supply chains over the next few months. In addition to the internal focus on the expansion and the industry's response to the RVO, we've seen the current market conditions highlight a lasting dynamic in jet fuel that we think it's important to note.
The Iranian war is certainly an extreme moment in energy, but there's a natural experiment buried in the event, and we've seen that industry is not equipped to meet a sustained increase in jet demand. Expecting jet fuel demand has been growing and is expected to grow faster than all other liquid fuels combined is important. The number of refineries are decreasing, not increasing. Refineries don't just make jet. Thus, as gas demand slows, the jet shortage grows. SAF can be made at much higher yields and much more intentionally than traditional jet. SAF receives the additional benefit of environmental energy credits, and farmers are rewarded for growing more domestic feedstocks. With an increase in SAF in the RVO, we can make more biofuels to supplement traditional energy, we generate environmental credits, and American farmers grow more and make more money to sell us the feed.
It's an extremely efficient and circular system with dramatic positive impact to our country. Montana Renewables is in the perfect position to support this opportunity. With that, I'll turn the call to David.
Thanks, Todd. Let's get into our results. As Todd mentioned, the first quarter was a transformational quarter for the business as well as strategically. In terms of financial results, the company generated $50.1 million of adjusted EBITDA with tax attributes slightly down from the $55 million generated in the first quarter of 2025. Despite the extraordinary margin environment for both of our businesses, we didn't fully capture the opportunity the market provided due to a previously disclosed operational event in Shreveport, which was ultimately resolved, and the plant is now fully operational. Late in the quarter, organic chlorides were discovered in our crude stream, which caused a loss of about 750,000 barrels of production. Organic chlorides are a serious risk if not identified and managed appropriately.
They're an inorganic contaminant not naturally found in crude oil, which appears in the naphtha fraction of the feed used to produce gasoline. Our industry has seen serious consequences when these are carelessly blended into crude because they cause rapid erosion of steel and/or Shreveport team noticed the corrosion, identified the cause, and acted swiftly to manage the risk of placing the directly impacted naphtha processing equipment and examining the entire facility as a caution. The event, which cost us over $30 million of lost opportunity given the elevated margins at the end of the quarter, is now behind us. The plant is running about 50,000 barrels per day, has done so most of April, and I appreciate the team managing through this complex situation safely and urgently. Turning to slide seven and our Specialty Products and Solutions segment, our underlying business remains strong.
We generated $44.3 million of adjusted EBITDA during the period compared to $56 million generated in Q1 2025. We believe that the unique elements of our business model, integrated assets that provide optionality combined with commercial excellence to capture value, are well suited for periods of extreme volatility like we are in today. As a comparison, today's business environment is similar to 2022 when we saw similarly elevated crack spreads and specialty margins. In that year, the company generated over $400 million in adjusted EBITDA. Our integrated business allows us to produce fuel and take advantage of the attractive high-margin fuel environment. Using current strips, the 2026 full year two-one-one is over $42 per barrel, nearly double what we saw on average over 2025.
Our specialties business, we've now posted the sixth consecutive quarter of sales volume exceeding 20,000 barrels per day. This was accomplished despite the outage at Shreveport, which primarily impacted our fuels business. Specialty margins during the period were temporarily compressed due to the extreme spike in crude oil price. The commercial team acted quickly, pushing through numerous price increases to offset the impact of rising feedstock costs. We've put in place more than $20 price increases to date and anticipate seeing the future benefit of this in the second quarter. These price increases, plus the elevated fuel margin environment, position us well for what we believe will be a strong second quarter where we expect to generate additional cash flow during this attractive margin environment.
To add to that, and to fortify our ability to achieve our deleveraging targets, we've entered into crack spread hedges for portions of 2026 and 2027 fuels production. Currently, we have hedges for approximately 10,000 barrels per day or around 25% of our fuels production on the 2-1-1 crack spread. We entered into a portion of these 2026 hedges at around $22 per barrel of the two-one-one crack using Argus or CBOT for the gasoline leg of the hedge. Note that CBOT trades at a $3-$4 discount to Gulf Coast 87.
Those hedge positions were put in place at attractive historical levels even before the large run-up driven by the conflict in the Middle East, and those cost us around $6 million in realized hedge losses during the period. The next tranche, which was added recently, was 10,000 barrels of production for 2027 at levels closer to $27 a barrel, also on a CBOT basis. How these hedges end up is a function of what happens from here in the Middle East. For us, it's about making sure we deliver on our strategic objective, which is generating strong cash flows to accelerate deleveraging and de-risking a portion of our fuels productions at these extraordinarily high margins. This puts us in a place to support that goal while also leaving plenty of room for upside of our remaining fuels production.
Turning to slide eight in Performance Brands, we also have continued to benefit from our commercial excellence strategy in this segment at a truly premium brand in TRUFUEL. We reported $12.6 million of adjusted EBITDA. The results were partially impacted by margin compression and the normal price lag associated with a more retail-oriented customer base. While we have been also implementing price action, this branded space takes about 60-90 days to fully reflect the increases compared to the less than one-month lag in our SPS business. Taking a closer look at adjusted EBITDA on a like for like comparison basis, we've seen continued growth. As a reminder, the results of Royal Purple industrial business are reflected in the first quarter of 2025 financials when we owned that portion of the business and not included in the current period following the divestiture in March.
Last March. Our commercial and operational teams in less than a year have successfully offset the loss EBITDA associated with Royal Purple industrial business through disciplined cost controls, growth of our trusted brands, and our strong customer relationships. We announced that our TRUFUEL business in February had posted record monthly results, that momentum continued throughout the entire quarter as we posted record sales volume, and we posted another monthly volume record in April. Customers continue to place a premium on the value of our engineered fuels, our innovative packaging options, and overall product reliability and convenience. Turning to slide nine at our Montana Renewables segment. Adjusted EBITDA with tax attributes was $10.2 million for the quarter compared to $3.3 million in Q1 2025. Renewables EBITDA with tax attributes on a Calumet-owned 87% basis was $8.8 million.
As Todd mentioned, we've delivered the MaxSAF 150 expansion on time and on budget. With our new capacity, we are stepping into a market with significant tailwinds from a transformational product mix shift between renewable diesel and SAF that will deliver a 4- 5 fold increase in SAF volumes on an annual run rate basis. The business is incredibly well-positioned as we ramp up production with the new RVO and a diversified portfolio of customers with a contractual SAF premium of $1-$2 per gallon over renewable diesel, all of which is underpinned by our industry-leading low cost structure. As these dynamics further take hold, our renewables business is at a positive inflection point, and we leverage the strategic investments we've made in the business over the last several years with an expectation of meaningful cash flow generation.
As Todd mentioned, following the 2023 RVO and trough-like margins the industry managed through, look no further than the RINs pricing in 2026 to see that that recovery was already in process prior to the extremely constructive RVO announcement in March from the current administration. Finally, capital expenditure during the quarter within MRL was approximately $15 million and funded entirely by cash within MRL on the balance sheet. Before leaving this segment, our Montana asphalt results were in line with the prior year as first quarter 2026 reflected typical seasonality and price lag impacts in our wholesale asphalt business. We are moving into a seasonally stronger period in Q2, as well as an extremely supportive crack environment for fuels also in this segment.
As we've routinely said, we expect the site to produce $30 million- $50 million of annual EBITDA range in a normal environment, and we look forward to the opportunity at hand as these stronger margin environment. Let me now turn the call back to Todd for his concluding remarks.
Thanks, David. Before I turn the call back to our operator for questions, I wanted to remind those joining that we have filed our proxy materials and the voting window is open. For all shareholders listening, we appreciate your support. It's almost two years since our conversion from an MLP. We set out to create a stock with much higher liquidity and a broader investor base. Over the past few years, we appreciate the new investors that have joined us as our daily trading volume has increased over tenfold. Our strategy is focused on creating shareholder value, and we're always available to our investors to further discuss our proxy materials and our business strategy. Thank you for joining us today, and I'll turn the call back to Andrea for questions. Andrea?
Our first question will come from Amit Dayal of H.C. Wainwright. Please go ahead.
Thank you. Good morning, everyone. Thank you for taking my questions. The story seems to be in a really good place, guys. You know, the demand and pricing environment is pretty solid. I'm just trying to get a sense of the risks. Are these primarily coming from, you know, the cost and input side of things or new supply coming online? Can you share any sort of drivers where, you know, we should be paying attention to that may, you know, provide any sort of unexpected surprises, I guess, in terms of, you know, how the setup is right now?
Hey, Amit, it's Todd. Thanks for the question. You know, it's, I'd say we spoke a lot about the market today. There's not a single element in the market in either Renewables or Specialty or kind of more broadly fuels that I'd point to and say has any singular risk that, you know, is keeping us up at night. I think the market's in really good shape. We talked about the reasons why, you know, especially markets supported, you know, by disruptions globally and is just a normal, strong, stable market in any environment. I'd say if there's anything, we just acknowledgment that it's very volatile out there and there's still a meaningful conflict going on and we could see pretty massive volatility.
We've seen how quickly these markets can move. As we sit here today, I think we have a lot of confidence in our commercial team to react accordingly no matter what happens. They've proven that. You know, price increases are in on the Specialty side, so we feel pretty comfortable with where we're at. We'll see a little bit of, you know, margin tightening in Performance Brands while we kind of play through the lag there for the next couple of months. Other than that, we feel like we're positioned pretty well and really looking forward to the opportunity the market's offering.
Thank you, Todd. Just, next one for me is on the SAF side of the story. You know, your SAF contracts, where you are getting the $1- $2 premiums, you know, how long are these in place for? Do you think when these renew, you'll be able to get similar or better terms?
Yeah, Amit, it's Bruce. Thank you for the question. The term contracts are evergreens. The notice periods, you know, we have a distribution of those at this point because we've been selling SAF for three years now. As we step into these, you know, we're gonna kind of have different notice period dates. What I could tell you is the ones that roll have renewed within that guidance range. The new ones are a portfolio of, you know, kind of various next notice dates going forward. You know, they stay with us as evergreen relationships.
I'd just add a little bit of that. You know, on average, these are typically two, three year type evergreens. As Bruce stated, so far they've all continued to roll forward. As far as the margin environment ability to renew, we feel quite comfortable with where those have been. As we've rolled forward contracts historically, we've certainly not had a problem, you know, re-upping them and adding additional supply as we've been doing here recently over the last six months or so. We haven't seen any setback in margins. We think that the underlying fundamental support is there, given all of the, you know, demand for the renewable energy credits, the underlying Scope 3 credits, et cetera. Pretty bullish on the outlook there and our ability to continue growing our marketing.
Good to hear, guys. That's all I have. I'll step back in queue. Thank you so much.
The next question comes from Conor Fitzpatrick of Bank of America. Please go ahead.
Good morning, everybody. Thanks for taking my question. I wanted to dig a bit into maybe an update or a refresh on the second phase of SAF capacity expansion. You know, it's still a ways away, and it could maybe take a more modular form, but I was wondering if there was just any update on CapEx build parameters, engineering, and obviously the contracts coming in for this first phase are pretty bullish, pretty supportive of continued demand. Sounds like there's still the opportunity there to expand at a similar profitability to the first phase.
Hey, Conor, thanks for the question. It's Todd. Yeah, look, we've been focused on the current phase. Obviously, we're just now commencing operations. It's very exciting with where we're at. We wanna stay focused there. We've got our team kind of head down, operating, focused on that operations. At the same time, we do have an independent project team that's certainly looking at kind of the next phase of a modular opportunity. It's probably a little bit too early to get ahead of ourselves on announcing that. We hope to be able to talk more specifically to that soon.
I think in the past we've said, "Let us get a chance to get up, get through this commissioning ramp up here over the next couple of months," and it will certainly be out, and looking forward to doing so in the not too distant future to talk about what's next and how the follow-up steps can play. To your point, you know, we certainly are bullish about the opportunity to continue to expand. We think the opportunity is there, it's readily available, and we're not seeing any, you know, demand gaps that would hinder that. We're just gonna try and take it one step at a time here, but hope to be able to talk about our acceleration plan and next steps pretty soon.
Great. Thank you. I guess a follow-up is, it looks like there are maybe still some impediments to biodiesel capacity ramping to full or peak rates again. I think there are various reasons to do with physically operating, such as feed cost basis in the Midwest, you know, diesel pricing and biodiesel pricing specifically in different regions of the U.S., ability to have the actual cash inflow from 45Z credits soon enough to incentivize production. I was just wondering, you know, how far are we maybe from biodiesel producers, the marginal ones that will be needed to supply the market, until profitability so that they can ramp up fully?
Hey, Conor. Bruce. Yeah, I think that was a good frame of what some of the issues and drivers are. There's two fundamental questions you asked, what about their volume and what about the economics that follow from that? Our supply stack.
Says we're solidly back into a market environment where the prices are gonna have to incent the small biodiesel guys, the independent ones. Remember, some of them are running. Everybody's got their own specific, unique situation. That's why those stacked cost bars have a range to them. The question on volume is how fast and how many? Have these been permanently abandoned? You know, history shows us that it's kinda I call it ghost capacity, but it can come back faster than you think unless somebody just gave up and removed it. We're gonna find that out. You know, a lot of the analysts are calling for getting back into the 90% utilization range of biodiesel capacity by, you know, towards the end of this year.
Okay. Thanks for the color. That's all I have.
The next question comes from Josiah Knight of Goldman Sachs. Please go ahead.
Hey, team. Good morning. Thanks for taking our question. Maybe on the feedstock side of the equation for MRL, how much pressure are you seeing? Can you remind us of MRL's relative advantage and feedstock flexibility in navigating these costs? Thanks.
Hey, Josiah, it's Bruce. Thank you for the question. We have essentially unlimited feedstock flexibility. We set it up that way on purpose. You know, the pre-treater capability is what allows us to follow the market dynamics and pricing volatility. We're pretty aggressive at our monthly re-optimization. You know, we exist in the middle of the feedstock long area, so there's never been a question of any kind of physical shortage, and we seem to do better on optimization and re-optimization when we look at our capture on percentages versus an industry index.
Got it. That's helpful. The follow-up, maybe on the base business, how are you thinking about the earnings outlook in the near and medium term, especially given some of the recent volatility for commodity prices?
Hey, Josiah, it's Todd. Look, I think, as we talked about during the script period earlier, we're pretty confident in the outlook. Obviously the fuel margin is incredibly positive right now. There's pretty meaningful supply disruption. We don't think this is something that just returns in a very short period of time. It's obviously not something that lasts forever, but it feels a lot like 2022, where you kind of just see the shock that we're seeing in the market and you look at inventories out there, and they're depleted not only here, but really throughout the globe. On Specialties side, we've talked a lot about our ability to push price increases through rapidly.
Commercial team did over 20 of them in a very short period across the product line. You know, at current costs, we're quite bullish on the outlook for both fuels and specialties. Obviously, we could see increased volatility from here and if we do, then we've demonstrated that we can react accordingly and we'll do that. I think big picture, the market's pretty constructive on a margin outlook basis, no matter where you look. You know, our specialties business has a domestic supply chain and access to feedstock, and you just can't say that on a global basis right now. You know, we'll continue to serve the market.
That's great. Thanks.
Yeah.
The next question comes from Gregg Brody of Bank of America. Please go ahead.
Morning, guys. Excuse me. You referenced 2022 as how to think about maybe Specialty material margins and the environment you're in. You know, those margins got up to the $90 range during that period, and you know, you've mentioned you'd be able to put through, be able to pass price through. Is that the type of environment we're in right now, or is it gonna take more? Do we have more steps we need to go to get there in terms of price increases?
Hey, Gregg. Yeah, I don't think right now we would look and say we're at $90 specialty margins going forward. I think when we talk about 2022, you're looking at just kind of analogies to the, to the whole demand period. You know, increasing crude costs create a little bit of lag in the specialties business. I think back in 2022, we were able to overcome that in a hurry. We've done the same here. We'll see what happens, right? With volatility in the back half of the year here, but feel pretty good about where we're at. As we sit here right now, I'd say Specialty margins are a tad lower than 2022, and fuel margins are a tad higher than 2022.
If you blend those together, then it's probably a good period. We're not trying to, you know, draw too tight of an analogy here. We're just saying the market feels pretty similar, where supply shocks are going to, you know, drive margins that are sustained for a period of time and provide the ability really to generate some excess cash flow and accelerate our de-leveraging plan.
That's helpful. Are you seeing any response from the consumer, as a result of the price spikes?
We really haven't right now as far as demand. Obviously everybody, you know, is getting their arms around these rapid cost increases. I think where we sit right now, there's such supply disruption throughout the space that consumers need our products. You know, a lot of our products go into consumer necessities and staples and not things that have massive price elasticity. We don't expect this to be something where we're seeing dramatic demand declines, et cetera. You know, we even saw record growth period at some of the downstream, you know, Performance Brands. We talked about a TRUFUEL record, et cetera. We've seen consumer demand continue to stay strong throughout the space. You know, how long that continues is, you know, probably a function of just general consumer sentiment and market volatility. As it sits right now, I think we're pretty positive on the outlook.
You just shifting to the organic chlorides issue which is in the past. Is there any remedies you have to make to the facility to fix any damage that was done at some point or just going forward?
No.
What's the risk of something happening again?
It's a good question. There's no further work needed at the facility. We took the event extremely seriously. We inspected the facility thoroughly. We made quite a few repairs at the time, and I'd say in a very conservative fashion. We weren't taking any risks with the situation. We took a big chunk of our naphtha train out of service and replaced it. We've installed quite a bit of redundancy in the sampling and quality monitoring throughout the system just to ensure that this can't happen again. You know, what typically happens in these types of scenarios throughout industry is chlorides, and a small amount of them can do a lot of harm, sneak in with crude supply and bypass the upfront QC checks.
I think that's what happened here. We're still, you know, fully investigating the deal. If we can figure out what happened, we'd certainly be very aggressive, with, you know, any culprit that created that. As far as the current go-forward position, the facility's operating really well. There's no sustained damage. We aggressively attacked any repairs that needed to be made, and we've been up and running really strong for over a month now.
Got it. Just to shift into the deleveraging plan, you know, you highlighted that you'll use cash to deleverage. You're clearly set up for a windfall here from both the restricted group assets and MRL. Does that change the way you're thinking about potentially monetizing MRL to pay down debt at restricted group? Or that's still the plan right now?
No, I'd say the plan still remains as it has been. You know, ultimately, we think that Montana Renewables is going to present an opportunity to monetize at some point. We're well on track to accomplish that. Obviously, this recent RVO was a major step in the right direction. No game plan changes there. We think the next step here is just showcasing what the earnings power of this business is with both MaxSAF project that's up and running and in a really positive RVO market. That's what we're focused on here for the foreseeable future, next quarter or two, and we'll go from there.
Great. I appreciate the time, guys.
Yeah. Thank you.
The next question comes from Jason Gabelman of TD Cowen. Please go ahead.
Hey. Thanks for taking my questions. You mentioned you're in a validation process of the MaxSAF expansion right now. Can you just talk about what the steps are to get it to a steady state or if it's already at steady state? Then in this type of margin environment, since the asset's been running, what type of margin are you seeing coming out of it?
Hey, Jason. Bruce, I'll start us and see if I touch those three points. Just on the last one, you know, the renewable diesel index margin hit over $3 a gallon at the end of the quarter. We're not calling for it to stay there. You know, if you look at our supply stack, we think the renewable diesel industry structure, you know, the equilibrated structure should be a bit north of $2. The SAF premium overlays above that. Just with that as a reminder of structure, that's how we've always talked about it. In terms of the operational current performance, we did restream the unit after the extended turnaround plus capital projects. Those are the modifications that we've called MaxSAF 150.
We had a little bit of a sidestep on an unrelated electrical power interruption to the site, so we had to restream it a second time. With that behind us, you know, we're finishing the ramp up. We have a performance test design that's probably maybe four weeks out. You know, the catalyst comes with performance guarantees. We've modified the hardware, and we wanna test that we've delivered the engineering expectations. You know, I think we'll have more intelligence in, you know, in a few weeks. No reason, nothing that we see, gives us any reason to think that we've, you know, we've underachieved in any way. We're, you know, we're excited about the go forward.
Got it. Can you also remind me just from an OpEx standpoint, if there's any change on unit OpEx relative to where the initial MRL was at?
Our track record of improving controllable costs and, you know, we got down to something like $0.38 a gallon. That's a chart we publish occasionally. It's pretty compelling. We don't think that we have any kind of reversal on that just because we're fractionating more kerosene out of the total reactor product.
Got it. Thanks for that answer. Then maybe just turning to liquidity. There's been a lot of volatility in the market, and you've seen in some of your refining and biofuel peers, working capital derivative hedging kind of headwinds related to that commodity volatility that we've seen. Have you seen that to a large extent? Can you talk through impacts on cash flow as a result of the volatility and if you would expect that to reverse over time?
Yeah. Yeah. I just start out by saying that, you know, we kind of feel good about our liquidity position and the cash that we're kind of generating in the current environment, kind of after some of the operational things that we saw at Shreveport during the quarter. We've obviously seen a big run-up in crude price. That does impact us, you know, a couple of different ways. One, on the inventory cost that we need to buy. You know, there's a little bit of a lag as we buy into the market. Also accounts receivables. You may have seen that, you know, we were up over $100 billion as the prices that are getting passed through at a premium to, you know, crude just roll into our AR.
There was kind of a big draw on working capital during the period from that run-up that was exacerbated by the downtime that we saw at Shreveport. We're already seeing kind of almost a total unwind of that. We're already seeing it in April. There'll be, you know, a little bit more, you know, into May. Just to touch a little bit, you know, on the liquidity hat, you know, we did this tack on for $150 million kind of earlier in the year. You know, we thought about that as a way to kind of at a pretty cost neutral, even at a premium, kind of pay off some of our 2028s when the call protection steps down in July.
We're looking at this current volatile environment. You know, we don't know how long it'll last, but we were in an attractive position to kind of take from the market, you know, kind of pre-reduce that debt and use that extra cash to balance kind of the spike in crude. As we move forward here, I think we'll still use that cash to pay down debt. We'll just reevaluate, you know, what the market looks like, you know, closer to July when our call protection steps down and, you know, what's happening in the world.
All right. That's great. Thanks. That's all my questions.
This concludes our question- and- answer session. I would like to turn the conference back over to John Kompa for any closing remarks.
Thank you, Andrea. On behalf of Todd and the entire management team, I'd like to thank everyone for their time today and interest in Calumet. Have a great rest of the day. Thank you.
The conference has now concluded. Thank you for attending today's presentation, and you may now disconnect.
