Q4-2023 Analysis
Danimer Scientific Inc

Revenue Decline and EBITDA Loss; Outlook for 2024

The company's Q4 total revenue fell by approximately 28% to $10.9 million, primarily due to decreased sales of PLA-based resins, which dropped by 74% because of the Ukraine conflict. Despite an 11% growth in PHA-based resin sales, gross losses widened to $6.4 million from $2.7 million a year earlier. Adjusted EBITDA loss worsened to $10.7 million in Q4 from $8.6 million, but yearly adjusted EBITDA improved by $6 million year-over-year, showing cost control progress. End-of-year cash was at $59.2 million with a total debt of $382.8 million. For 2024, the company guides an adjusted EBITDA loss between $22 million and $32 million, CapEx of $8 million to $10 million, and expects to end the year with $20 million to $25 million in cash.

Overview of Financial Performance

In the fourth quarter, the company faced a decrease in total revenue, which came in at $10.9 million, dropping from $15.3 million in the previous year, marking a 28% decline in product revenue. This decrease was significantly influenced by a 74% fall in PLA-based resin sales, linked to issues arising from the conflict in Ukraine. However, there was a silver lining as PHA-based resin sales witnessed an 11% growth in the same period.

Profitability and Cost Management

The company reported a steeper gross loss of $6.4 million this quarter, compared to a loss of $2.7 million in the prior year, with the increased loss mainly due to the lowered PLA sales coupled with elevated depreciation expenses. On an adjusted basis, reflecting non-cash items like depreciation and stock-based compensation, the gross loss was $1.2 million, a downturn from an adjusted gross profit of $2.0 million last year. Encouragingly, R&D and SG&A expenses saw a reduction due to cost control measures, leading to a year-over-year improvement of $1.1 million.

Cash Flow and Capital Expenditure

Cash reserves slightly decreased to $59.2 million at the end of the fourth quarter, from $62.8 million at the end of the previous year. Still, the company managed capital expenditures well, aligning with the latest guidance range at $27.7 million for the year. The company's outlook for capital expenses in 2024 is forecasted to be between $8 million and $10 million, reflecting minimal spend on the greenfield project during the year.

Debt and Liquidity Outlook

Total debt stood at $382.8 million, primarily consisting of various forms of long-term debt. The company's unrestricted cash balance is expected to be between $20 million to $25 million by the end of 2024, factoring in adjusted EBITDA estimates, capital expenditures, and cash interest obligations. This projection also assumes improvements in working capital, such as reducing inventory levels and better receivables collections.

2024 and Beyond

Looking ahead, the company aims to capitalize on its potential to transform the plastics market, leveraging its developmental expertise and a solid customer base. With its focus on future goals, the company is confident in its capacity to significantly improve its financial position, projecting a narrower adjusted EBITDA loss range of $22 million to $32 million for 2024 as it continues to streamline its operations and grow its customer base.

Welcome to the Danimer Scientific 2023 Fourth Quarter Earnings Call. [Operator Instructions] I would now like to turn the presentation over to Mr. Blake Chamblee, the company's Investor Relations representative. Please go ahead.

U
Unknown Executive

Thank you, operator. Good afternoon, everyone, and thank you for joining us today for Danimer Scientific's 2023 Fourth Quarter Earnings Call. Leading the call today are Steve Croskrey, Chairman and Chief Executive Officer; and Mike Hajost, Chief Financial Officer. I'd like to note that there is a slide deck that accompanies today's discussion, which is available on the Investor Relations section of our website at danimerscientific.com. As we begin, I'll call your attention to the company's safe harbor language, which is published in our SEC filings and on Slide 2 of the presentation, I just referenced. On today's call, we may discuss forward-looking statements within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 as amended. Forward-looking statements include, among other things, statements regarding future results of operations, including margins, profitability, capacity, production, customer programs and market demand levels. Actual results could differ materially from what is expressed or implied in our forward-looking statements. The company assumes no obligation to update any forward-looking statements to reflect events or circumstances after the date hereof, except as required by law. Today's presentation also includes references to non-GAAP financial measures within the meaning of SEC Regulation G. We believe these non-GAAP measures have analytical value but note that they should be taken as supplementary measures of performance and not as alternatives to GAAP results. We have provided reconciliations for non-GAAP financial measures to the most comparable GAAP financial measures in our earnings release and our presentation. Thank you. And it's now my pleasure to turn the call over to Steve Croskrey, Chairman and Chief Executive Officer of Danimer Scientific.

Stephen Croskrey

Good afternoon, and thank you for joining us. The conclusion of the fourth quarter of 2023 marks the end of a challenging year as Danimer experienced delays in anticipated commercial launches. Despite these delays, we are greatly encouraged by our successes during the year, and we believe we remain well ahead of the competition in both deep understanding of the biodegradable plastics industry and the available production capacity to meet our current and future customers' needs. Some examples of our recent successes include the previously announced 20 million-pound PHA resin cutlery award for a large quick-service restaurant chain, or QSR, the start of a Nodax-based draw scale up with another large QSR, as well as the commercial launch of home compostable certified mini carrot bags under the Bolthouse Farms' brand completed in conjunction with our converter partner, Columbia Packaging Group. We are excited about our partnership with Delta Cafes in the development of single-use coffee pods that will meet stringent EU environmental standards. Additionally, we have made great strides in research and development efforts with several of our customers including Mars-Wrigley, Kemira, Eagle Fishing and Pepsi. We have also announced the completion of our Rinnovo pilot plant in Rochester, New York. This allows us to demonstrate the capabilities of this unique PHA material in meeting our end customers' needs and provides an important proof of concept supporting our designs for commercial scale production. We remain engaged with a major oil and gas company as a colocation partner for a commercial facility and are also in negotiations with another partner to engage in research applications using our Rinnovo PHA. Our work with Chevron Phillips Chemical to develop and commercialize cast extrusion films, blown extrusion films, injection molded parts and rotational molded parts using renewable polymers continues to progress in a very positive manner. Our primary focus remains our development and commercialization efforts in the quick-service restaurant channel. We work closely with the top 3 QSRs as measured by U.S. system-wide sales for a variety of end-use products including straws, cutlery, film wrappers, bowls and container lids. Our previously announced 20-million-pound annual awards provide cutlery resin to a large global QSR chain continues to progress as we anticipated. We have entered the first stage of scale up and expect the first commercial shipments in the second quarter of 2024, with cutlery being delivered to at least one customer distribution center during the third quarter of 2024. We expect this award to reach full run rate in the second quarter of 2025. We have also recently learned an opportunity to expand both in geography, specifically into Asian markets, including Japan and into additional end product categories, including straws and film wrappers for cutlery with this same customer. Scale up of our Nodax-based straw resin with another large QSR has progressed and is expected to enter commercial launch during 2024. The success of these trials has also led to a joint development agreement with the same QSR for lids and coated paper containers. We also continue to advance in the commercialization process of compostable cups using our PHA resins for both aqueous and extrusion coatings. This has been a technically challenging area, but we are very close to a successful outcome. Our partner, Kemira has recently exercised an option to extend their license and exclusivity with us to commercialize biodegradable aqueous barrier coatings to be used on paper-based food and beverage applications. This extension builds on our long-standing successful development partnership, which began in 2020 and bodes well for the future. The QSR industry continues to rapidly move towards more sustainable solutions, and we are thrilled to be a part of this transformation. We partnered with Delta Cafes, a coffee roaster and coffee packaging company in Portugal, to develop a compostable single-use capsule for their Delta Q line of ground espresso. We have begun commercial shipments of this resin in the first quarter of 2024. These pods are in full compliance with proposed new EU regulations requiring any coffee pods sold to meet new compo standards. These capsules degrade inside industrial composting environments, leaving no microplastics or other residues that would harm natural ecosystems. As a reminder, coffee pods and tea bags represent a potential GBP 500 million opportunity in the European marketplace. We have also expanded our research and development contract with Mars-Wrigley to further our relationship with their snacking division, including the completion of testing and validation of a unique product packaging using fully biodegradable PHA materials this year. Our partnership has also made significant progress towards the development of compostable PHA packaging that showcases the desired performance for products in Mars Pet Care and Food & Nutrition businesses. Another promising R&D project is focused on the sports fishing industry. Eagle Fishing, an innovation leader in the industry, has partnered with us to develop a new PAK technology for soft fish base. Development of this new PAK soft plastic technology is nearing completion and full-scale testing can be underway by midyear, which will help to replace the plasticized PVC odors that harm our aquatic ecosystems. This is an exciting market for us as we continue to grow in new directions and end-use applications with our Nodax PHA-based resins. We have successfully completed a joint development agreement with PepsiCo to create home-compostable multi-air films for use in snack food packaging. Our combined R&D efforts have led to the development of a multilayer packaging structure that meets the practical requirements for protecting the product while offering a sustainable disposable alternative. The expected demand growth for our PHA-based products allows us to reaffirm our projected profitability time line for our Kentucky operation and the company in total. We expect our Kentucky facility on a stand-alone basis to become EBITDA positive during the second half of 2024 at plant capacity utilization of just over 30%. We expect the total company will become EBITDA positive when our Kentucky facility reaches 70% to 80% capacity utilization near the start of 2025. To support the customer revenue growth outlined above, we decided to further augment our liquidity position to help ensure an adequate cash runway. As we previously announced, we recently completed an equity offering generating $13.5 million of additional cash after customary closing fees. This additional liquidity, along with our projections for a decreasing cash burn rate as volumes increased at our Kentucky facility will aid us in meeting our forward cash needs. I would like to now draw your attention to Slides 5 and 6 in our investor presentation, which provides a visual reminder of our sales cycle process. From the initial lead to commercialization, this can be a lengthy iterative process rather than a linear one. But we have been at this a long time. We currently have 85 customers in the material selection cycle ranging from initial sample production to larger scale trials to market testing, to regulatory and certification work. This cycle establishes the long-term sales pipeline for our business. We recently announced 2 new Board members. We are honored to welcome Dr. David J. Moody and Mr. Richard Altice to the Danimer Scientific Board of Directors. Dr. Moody, who was appointed to the Board on January 17 of this year, is the former Chief Executive Officer of Jadex Inc., a U.S.-based manufacturing and material science company. He has over 30 years of experience managing chemical and polymer-related businesses. Mr. Richard Altice, whose appointment will be effective April 15, 2024, and is the former President and CEO of NatureWorks, a developer and manufacturer of biopolymers. He has over 30 years of sales, marketing, operational and management experience in the specialty chemicals and biopolymer industries. These new board members bring valuable industry perspective and experience as we seek to rapidly grow our business, and we are very excited about adding these seasoned executives to our team. Finally, we are entering the final stages of our due diligence work with the DOE Loans Program Office, and we look forward to negotiations on a projected term sheet. I will now turn the call over to Mike Hajost, our Chief Financial Officer, to update you on the financial results for the fourth quarter and on our outlook for 2024.

M
Michael Hajost
executive

Thank you, Steve, and good afternoon, everyone. I'll start with our financial results on Slide 7 of our presentation for those of you following along. Fourth quarter total revenue was $10.9 million compared to $15.3 million led by a product revenue decline of $4 million or 28% compared to the prior year level. PHA-based resin sales grew by 11% in the quarter compared to last year. And we continue to experience steady growth, but PLA-based resin sales fell 74% compared to last year, primarily due to the ongoing issues associated with the Ukraine conflict. We reported a fourth quarter 2023 gross loss of $6.4 million as compared to the prior year quarter's gross loss of $2.7 million. The year-over-year increase is primarily due to overall lower PLA sales as well as higher depreciation expenses. After adjusting for depreciation and stock-based compensation, we reported an adjusted gross loss of $1.2 million as compared to an adjusted gross profit of $2.0 million in the fourth quarter of 2022, primarily due to the lower PLA sales. R&D and SG&A expenses, excluding depreciation, amortization, stock bid compensation and certain nonrecurring items, totaled $9.4 million in the fourth quarter of 2023 compared to $10.5 million in the fourth quarter of last year. Our continued cost control initiatives across many areas of the business created this $1.1 million year-over-year improvement. Adjusted EBITDA loss was $10.7 million in the fourth quarter of 2023 and was at loss of $8.6 million in the fourth quarter of 2022. For the full year, we had an adjusted EBITDA loss of $39 million, which was in line with our latest guidance range of minus $37 million to minus $40 million. On a year-over-year basis, this represents a $6 million improvement over prior year's adjusted EBITDA loss of $45 million. Adjusted EBITDA excludes stock-based compensation, depreciation, amortization, interest and other nonrecurring items as reconciled in the appendix. Cash and equivalents at the end of the fourth quarter was $59.2 million as compared to $62.8 million at the end of 2022. Restricted cash was $14.3 million which is mainly held for future interest payments under our senior secured term loan. Capital expenditures were $2 million in the fourth quarter and $27.7 million for the full year which was in line with our latest guidance range of $27 million to $29 million. We ended the fourth quarter with a total debt balance of $382.8 million comprised mainly of our convertible senior notes, the senior secured term loan and our new market tax credit loans, which we expect will be forgiven starting in 2026. We continue to view the magnitude and timing of the customer ramp for PHA-based resins and our increased utilization to serve that demand from our Kentucky operations as the largest factors for variability in our short-term financial results. With the customer expectations described earlier, that will improve cash flow from our Kentucky operations, we are set to release our full year 2024 guidance. We believe our adjusted EBITDA will be in the range of minus $22 million to minus $32 million. With very little required spend on the greenfield project in 2024, we're expecting our total capital expenditures for the company to be in the range of $8 million to $10 million. We also expect to end 2024 with an unrestricted cash balance in the range of $20 million to $25 million. The ending cash balance range is driven by the adjusted EBITDA range as a proxy for cash flow, the 2024 CapEx range, known cash interest for the year based on our current debt structure, the net cash received from our recent equity issuance and significant improvements in working capital. The working capital improvements will be led by our opportunities to reduce inventory from artificially high current levels and our ability to improve our overall receivables collections to include collections from completed R&D contracts. This ending cash balance range does not include potential cash or liquidity from other financing transactions that are available to us. I'll now hand the call back to Steve for his closing remarks.

Stephen Croskrey
executive

Thanks, Mike. In conclusion, and as we look towards 2024, we are focused on the immense long-term opportunity to transform the plastics market. With our developmental expertise, capacity footprint and a growing blue-chip customer base, we believe we remain well ahead of any competition and have a clear path to deliver on our goals for 2024 and beyond. Thank you for your time today, and we look forward to updating you on our progress. We will now open the line for questions.

Operator

[Operator Instructions] Your first question is from Jon Tanwanteng from CJS Securities.

J
Jonathan Tanwanteng
analyst

My first one is, could you talk a little bit more about your expectations for timing and ramp up through the year? It sounds like you're getting a little bit better visibility just as related to the color and some of the other contracts that you may have seen, but I'm wondering if you have any more -- a more detailed breakdown [indiscernible] does ramp by quarter?

S
Stephen Croskrey
executive

Yes, Jon, I don't know that we can give you a detailed ramp by quarter, but I can try to color it in here. Most of this is going to be driven by the color award, which is significantly larger than some of the other opportunities. As we mentioned already, we expect to be in distribution centers by Q3 and to be at full run rate with that by Q2 of next year. Where the project is right now, the converters that have been aware of the business are in the process of getting tools built specifically for this program. One converter has ordered about $9 million worth of new equipment that will be delivered in April. So it's well underway. We don't have specific production requirements yet. But we know what the goals of the customer are that support our point that this will be at full run rate by Q2 of next year. And I'll just point out, that's a GBP 20 million, and that will more than double our PHA sales. And one of the exciting things now is that we're also going to be doing the plastic wrap for the cutlery and that's going to also add significantly to the award.

J
Jonathan Tanwanteng
analyst

Got it. That's helpful. Second, I was wondering if you could give us an update on the DOE loan program. And if there's any movement there, or any changes to expectations?

S
Stephen Croskrey
executive

Okay. We are at the point now where the DOE is nearing completion of its due diligence, and we expect to be negotiating the terms and are looking for a conditional offer conditional commitment by sometime in Q3.

J
Jonathan Tanwanteng
analyst

Got it. And the funds would be available around Q4 in that time line. Is that fair to think about it?

S
Stephen Croskrey
executive

Well, that's possible, Jon. Yes, that's possible, Jon, but it will also depend on what the actual conditional commitment is. So depending on what requirements there might be. We know what we've asked for, but we don't really know exactly what we're getting. So there could still potentially be monies that have to be raised and so it just kind of depends on how much in terms of how long that could take. But we're hopeful that we can get it done by Q4. But until we actually see the term sheet it's really hard to predict exactly.

J
Jonathan Tanwanteng
analyst

Understood. And then lastly, as you think about the greenfield and the time line it might go up and depending on what you get financing for, are you seeing any movement in customers who are willing to take -- could -- commit to either an anchor customer or volume indications, which may indicate they may need the greenfield?

S
Stephen Croskrey
executive

Yes. I would tell you that some of our customers that are included in this current ramp are moving forward with the expectation that we're going to get the greenfield deal done because they know that we won't be able to handle their entire requirements just out of Kentucky. So we think that's a favorable thing, obviously. And we expect, as we continue to get some of these other development projects across the finish line that, as we've said, many times, there's multiples more demand in our pipeline than what we can handle even with the greenfield.

So -- and I would point to one specific need, which are compostable cups, drinking cups, as we get that over the finish line, that's going to create a tremendous amount of demand and we'll require the greenfield to support that.

Operator

Your next question is from Thomas Boyes from TD Cowen.

T
Thomas Boyes
analyst

Maybe just a follow-on, just a bit on the DOE loan. More on the process -- kind of a high level, assuming that the loan conditional improvement comes in 3Q '24, for the $180 million that you've already spent on Bainbridge. Would you get 80% of that all at one time? Is that kind of how that works? And then maybe would it be fair to assume that there's a one quarter lag on CapEx that you spent in 1Q of '25 showing up in 2Q and then the 3 and 4 and so on and so forth. Is that kind of how the timing you think works?

S
Stephen Croskrey
executive

Thanks for the question, Thomas. Let me make sure I -- I'll try to answer it and make sure I'm answering the right question. So we're going to get as part of the term sheet, an LTV loan to value. So we'll get credit for the roughly $190 million-ish that we've already got into the project will count towards our equity. And whenever -- if there's a gap, we'll have to raise additional equity. If there's not a gap, we'll just get started right away, and it will be again immediate draw against the loan proceeds. So there won't be like a step thing each month or anything like that. It will be -- when the loan closes, it will all be available.

T
Thomas Boyes
analyst

Okay. That's helpful. And then just for my second one, could you talk a little bit more about the joint development agreement for the lids and coated paper containers. I know you already have made significant progress internally on lids. And in theory, could that speed up the sales process that you've outlined in the deck?

S
Stephen Croskrey
executive

Yes. I can't really offer too much more, Thomas, to that other than it's for major QSR but these are lids. It's very similar to lids for cups but these are lids specifically for food containers. So it's a little different. But every time we do one of these projects, we learn things, and we learn things that we can translate into other areas. So it's all good.

T
Thomas Boyes
analyst

Got it. And if I could sneak one more in. Just any update on feedstock pricing? What you're seeing in the market? What you've locked in, would be helpful?

S
Stephen Croskrey
executive

Yes. Mike, do you want to take that one?

M
Michael Hajost
executive

Yes, sure, Thomas. Yes, I think overall, in Q4, our canola prices averaged right around $0.86 a pound and we're seeing really about the same type of price here in Q1. It's -- as we look forward here through the rest of the year, where we can -- projecting those prices to move down to about $0.70 by mid-year. And we're also expecting to kind of end the year somewhere in the mid-$0.60 range. So we're seeing a nice decrease in the prices and we're starting to lock some of those in.

Operator

Your next question is from Laurence Alexander from Jefferies.

L
Laurence Alexander
analyst

Just want to start with the filtration process for the customers, the 85 that you mentioned, does that materially change the aggregate potential demand pool that you have compared to what you've talked about previously? Or can you give some sense of kind of if all of those customers did ramp up, how many plants of potential demand that would represent?

S
Stephen Croskrey
executive

Yes. Laurence, in kind of just big round numbers, I would say that those customers represent at least 3x more capacity than is available in Kentucky and the greenfield. And obviously, that's a conservative number without throwing like everything added. That's just the specific projects we're working on. And to be clear, that -- the 85 doesn't necessarily represent a change. It's just -- we've been looking for a way to try to demonstrate to help investors kind of understand the process better and to kind of see where things are. And so this is something we're going to -- we'll continue to refine, but we'll continue to track this in the future and present that kind of information. So any feedback we get on how that looks and how we might do it better would be helpful.

L
Laurence Alexander
analyst

You'll probably get too many metrics, we all want. Speaking of which, one that would be helpful is in terms of the customers who you won earlier and who you've been ramping up with, could you just give us a sense for how much churn you've had, kind of the customers that are increasing the volumes they take versus customers who are dropping out because products either didn't hit their specs or their needs changed?

S
Stephen Croskrey
executive

Sure, Laurence. If you look on Slide 5 and look at the customers on the right, those customers are all growing. And I would say we have never lost a customer once we had them at kind of full run rate. We might -- we had had maybe one customer in the past and this has been a number of years ago, where they launched -- they probably didn't understand their own specifications. It was a smaller company, and we launched, and then they found out things after the fact that, that didn't work for them. But other than that, we have not lost a customer. All these customers are happy and growing with us.

L
Laurence Alexander
analyst

Okay. Great. And then just what's the current market expectation or customer expectation or your messaging to them around when you use a greenfield, do they expect as volumes ramp a significant drop in ASPs? Or we be thinking about kind of flat to modest erosion in mix as you get economies of scale?

S
Stephen Croskrey
executive

Yes, sure. I understand your question. We have talked with some of the larger customers, we've kind of shown them some expectations over like a 10-year period of what that can look like as we scale and what's possible. But we have never specifically offered anybody lower pricing once the greenfield comes online or had any specific discussions like that.

L
Laurence Alexander
analyst

Great. And then just lastly, can you update kind of the market prospects for the Novomer technology, particularly into the aqueous film applications?

S
Stephen Croskrey
executive

Sure. So we are -- as you know, we've just completed the scale-up of the new pilot plant, and that will allow us enough volume to be able to sample some of these customers that will then be able to create demand by validating the material. We have -- are in the middle of negotiations with another major chemical company for a development agreement to support that. And as you know, we're working with Chevron Phillips on a couple of those projects as well. And we have a kind of, just call it, a verbal agreement at this point with -- because we're waiting on the customer traction now, but we have an agreement with another major oil and gas company for colocation venture. We can't -- I can't talk to anything on the aqueous side, but on the film side itself, what we're seeing is, if you remember, Laurence, when we bought that, that one of the things we were adding was, that the barrier properties of that material is much better than other commercial biopolymers, significantly so. And what we're seeing now is it's also better than fossil fuel-based products. So I keep telling people we have a killer app here. When we can get that commercialized and combine it with Nodax, we're going to be able to create applications that none of the other biopolymer competitors that are in the market today or even the ones that are trying to get into the market would be able to compete with on the snack food side because of the barrier properties.

L
Laurence Alexander
analyst

And then just sorry, one last one, and then I'll hop back in the queue. Is there a -- would all of those agreements, if they did pan out, do those represent any significant capital requirements on your part? Or is the goal on that side of the business to be mostly capital-light?

S
Stephen Croskrey
executive

Well, the goal is to be capital-light, but worst case, if we do a co-location, which we're going to do it, that's just how it's going to be done because those suppliers, they have the raw materials that we need, these big oil and gas companies, and so that's just the natural way that it will work. If we do that, the -- that will reduce the CapEx requirement because we will piggyback off of their infrastructure for things like utilities, chillers and electricity and things like that. So we can reduce our capital requirement that way. We're hopeful that we'll find a partner through this process on the commercial side that would like to participate. And we think if we get that, and we think the co-location partner will also want to participate and we can reduce our CapEx requirement even more. But the beauty of this product is that the CapEx cost on a per pound basis is 1/5 of the cost of a Nodax plant. And so even if we have to fit the bill, we expect to be able to do it on a project financing basis.

Operator

[operator instructions] and your next question is from Jon Tanwanteng from CJS Securities.

J
Jonathan Tanwanteng
analyst

I just wanted to follow up on that last one would be, the catalytic PHA. I was wondering when is the earliest you think you could see commercial volumes in that product? Just given the deals that you're working on now, the partners and the kind of the -- with the pilot starting up?

S
Stephen Croskrey
executive

Yes. Look, I think you've got to kind of assume a couple of years to build a plant. I mean, it can be done more quickly. But just to be safe or fair in the analysis here, I'd just call it 2 years to build a plant. And since we're -- we don't actually have that customer partner ready to negotiate. We've got the customer partners that we think we're going to be negotiating with, but they've got to validate the material with their customers first. So I think you got to add -- probably add a year to that 2 years at any given time. So I think 3 years out is fair in terms of an earliest date.

J
Jonathan Tanwanteng
analyst

Okay, great. That's helpful. Mike, if you could, just any thoughts on OpEx this year and if that's going to be -- remain relatively stable? Or if there's any growth plan in the budget guidance?

M
Michael Hajost
executive

Yes. I mean I think we're really pleased with how we've been driving OpEx cost down. If you look at the fourth quarter, we're down another $1 million year-over-year for the whole year 2023 versus '22, I think we drove down $14.4 million, and we're expecting to reduce those operating costs again in 2024 year-over-year versus '23 in the range of about $4 million or so. We've gone through rationalizing headcount. We've gotten rid of a lot of outside services and consultants. We're utilizing our own staff and capabilities to do a lot of those things. We've gotten some better insurance rates. So a number of things across all the boards. We're looking everywhere. That's kind of where we ended up, to which we are really pleased because it's just been a nice year-over-year change now for a couple of years and getting those costs down.

J
Jonathan Tanwanteng
analyst

Got it. That's helpful and good to hear. And just last before I go. Just any thoughts on volumes in Q1? Just we're pretty close on the quarter anyways.

S
Stephen Croskrey
executive

Yes. We can -- we mentioned in our press release that our year-over-year growth with PHA for the quarter will be approximately 60%, and I think it will probably exceed 60% at this point.

M
Michael Hajost
executive

Jon, if I can add also on the OpEx?

S
Stephen Croskrey
executive

I'm sorry, Jon.

I'm sorry. Was there NPL in Q1 last year?

Yes. But we're not -- we haven't provided any guidance on that.

And Jon, I want to just add one thing. I think it would be good for everybody to know. In terms of your models, all that stock-based comp it's been running close to $56 million a year, I think, in 2023. And a lot of those large grants are falling off. We're expecting something that's closer to about $4 million for full year 2024. So I think that's just a good thing for everyone to kind of know not to have that large piece of noise in your models.

There are no further questions at this time. I will now hand the call back to Steve Croskrey for closing remarks.

Thank you for your time, everybody, and your interest in Danimer Scientific. We're pleased with our recent progress and the additional customer opportunities that have been presented to us, and we look forward to talking to you again soon when we present our first quarter earnings, which will be coming up in just several weeks now. Thank you.
