Sarika Dhadwal (Senior Director of Investor Relations)
Good morning. Thank you for joining Donaldson's fourth quarter and full year fiscal 2023 earnings conference call. With me today are Tod Carpenter, Chairman, CEO, and President, and Scott Robinson, Chief Financial Officer. This morning, Tod and Scott will provide a summary of our fourth quarter and full year performance and details on our outlook for fiscal 2024. During today's call, we will discuss Non-GAAP or adjusted results. For fourth quarter and full year fiscal 2023, Non-GAAP results exclude restructuring and other charges of $4.9 million and $21.8 million, respectively. Fourth quarter and full year fiscal 2022 Non-GAAP results exclude $3.4 million of charges related to the conflict in Eastern Europe. A reconciliation of GAAP to Non-GAAP metrics is provided within the schedules attached to this morning's press release.
Additionally, please keep in mind that any forward-looking statements made during this call are subject to risks and uncertainties, which are described in our press release and SEC filings. With that, I will now turn the call over to Tod Carpenter. Please go ahead.
Tod Carpenter (Chairman and President, and CEO)
Thanks, Sarika. Good morning. Fiscal year 2023 was a milestone year for Donaldson Company. From a financial perspective, we made great progress on the objectives laid out during our Investor Day in April. We delivered record top and bottom line results, ending the year with $3.4 billion in revenue and $3.04 in adjusted earnings per share, increases of 4% and 13%, respectively. Improved our operating margin by 110 basis points by expanding gross margin while continuing to invest in our strategically important higher-margin growth areas. Delivered cash conversion of 114%, primarily by reducing our inventory levels by over $84 million, and returned $256 million to our shareholders in the form of dividends and share buybacks.
We also made significant strategic changes to our operating structure, laying the foundation to drive Donaldson to the next stage of its evolution and position ourselves for future profitable growth. First, we completed our organizational redesign aimed at better serving our end market customers. Second, we introduced life sciences as a separate operating segment, allowing for increased transparency as we build out our presence in this important growth area. Third, we completed two new life sciences acquisitions, Isolere Bio and Univercells Technologies, companies with game-changing, disruptive technologies that complement our existing capabilities and offerings in the space. Importantly, and in conjunction with Investor Day, we also announced our Filtration for a Thriving Future sustainability strategy and 2030 environmental and social ambitions.
I am continually impressed by the resilience and dedication of the Donaldson employees, particularly with the backdrop of such a dynamic and pivotal year, and I am proud of their accomplishments. Now I'll cover some highlights from the fourth quarter. Sales of $880 million were down 1% year over year, driven by a decline in volume, partially offset by pricing benefits. The impact from currency translation in the quarter was minimal. Volumes continue to be impacted by aftermarket softness, largely driven by OE customer inventory normalization and weakness in disk drive due to market-related conditions and destocking. On the pricing side, as has been the case all year, strategic and value pricing to offset inflationary pressures remain critical for Donaldson. While most input costs have stabilized, our work is ongoing as we continue to see increases in some areas, such as labor and energy.
EPS in the quarter was $0.78, down 7% from prior year. We remain committed to investing in our strategically important growth areas, and during the fourth quarter, we continued those investments, which, in conjunction with the sales decline, resulted in a quarterly year-over-year decrease in earnings. With respect to operations, fill rates, on-time deliveries, and late backlog levels across the organization improved versus prior year as our operations teams continued to deliver for our customers. Throughout the company, while we execute today, we are also ensuring through our strategic investments that we are well positioned to drive future growth. To that end, first, on August 16, we opened our new manufacturing plant in León, Mexico. The 265,000 sq ft facility will help meet future demand, and importantly, was built to include leading sustainability technologies such as higher efficiency lighting, air conditioning, and compressor systems.
This new plant will produce hydraulic, lube, and fuel products. Also in August, Donaldson opened a 25,000 sq ft bioprocessing technical center in Durham, North Carolina. This state-of-the-art facility includes 20,000 sq ft of laboratory and clean room capabilities that will be used to bring Isolere's revolutionary IsoTag technology to market. Isolere's first research use product is expected to launch in the first quarter of fiscal 2024. Second, we are working to meet customer needs through significant investments in R&D and M&A. Specific to M&A, during the fourth quarter, we acquired our fourth life sciences company, Univercells Technologies. Univercells Technologies delivers the next generation of upstream to midstream bioprocessing technologies for cell and gene therapies by leveraging the strengths of process intensification and chaining. The company produces unique bioreactor systems that employ proprietary, single-use, fixed-bed bioreactors, combined with midstream processing capabilities, including depth and tangential flow filtration.
These systems provide measurable advantages over the competition in productivity, concentration, cost reduction, and footprint. This acquisition is part of our String-of-Pearls approach to become a differentiated solutions provider in the bioprocessing space, with a specific focus on filtration and other separation and filtration tools. Our current capabilities give us excellent coverage and growth potential across the bioprocessing production chain, with a focus on plasmid DNA, mRNA vaccines and therapeutics, as well as cell and gene therapies. We expect to add products and technologies through internal development and M&A, that will fill gaps in our current product portfolio and enable us to provide customers with complete solutions. We're excited about these investments and continue to focus on meeting the needs of our current customer base and growing addressable market. Now I'll provide some detail on fourth quarter sales.
Total company sales were $880 million, down 1% from prior year. Pricing was a 5% benefit. In mobile solutions, total sales were $543 million, a 5% decline versus 2022. Pricing added 6%. Performance in mobile businesses were mixed this quarter, with off-road sales of $103 million down slightly, mainly due to weaker market demand in the Americas and China. Aftermarket sales of $402 million were down 7% year-over-year, as we continued to see OEM customers draw down inventories to better reflect normalizing global supply chain conditions. Sales in on-road of $37 million were up 6%, resulting from solid equipment production rates. Also within mobile solutions, an update on China. Sales declined 15% versus 2022, and 10% in constant currency.
Overall, China continues to be challenging given the weak end market conditions, particularly with respect to off-road. That said, our long-term view has not changed, and the sheer market size, combined with our world-class technology and high-quality offerings, give us confidence in our ability to gain share in the China market. Now I will turn to the industrial solutions segment. Industrial had another strong quarter as sales grew 10% to $277 million, ahead of our internal expectations. Pricing added 4%. Industrial Filtration Solutions, or IFS, sales grew 11% to $241 million, driven by continued strength in dust collection sales and power generation project timing. Aerospace and defense sales were up 4% as a result of defense sales strength.
On the life sciences segment, life sciences sales were $60 million, down 12% year-over-year, below our expectations, driven primarily by disk drive as market softness and destocking continued. Importantly, we believe we are now seeing early signs of a slow demand recovery and expect a sequential improvement in disk drive through fiscal 2024 as data center and cloud computing demand recovers. Our long-term life sciences story is partially a function of realizing the full potential of our recently acquired capabilities, and it is worth noting that our acquisitions are generating growth, adding 340 basis points to sales growth in the segment this quarter.
I'm proud of our fiscal 2023 accomplishments, both financial and strategic, and because of the hard work of our Donaldson employees around the globe, we are better positioned than ever to deliver to all of our stakeholders in fiscal 2024. To that end, for the full year, we are forecasting sales, operating margin, and earnings at all-time high levels. More specifically, we are projecting sales growth of between 3% and 7%, or to $3.6 billion at the midpoint. Operating margin in the range of 14.7% and 15.3%, and EPS between $3.14 and $3.30. All records for Donaldson Company. Now I'll turn it over to Scott, who will provide more details on the financials and our outlook for fiscal 2024. Scott?
Scott Robinson (VP and CFO)
Thanks, Tod. Good morning, everyone. Fiscal 2023 was a record year for Donaldson. I would like to thank our global teams who came together, managed through our company-wide organizational redesign, and delivered results consistent with the expectations we laid out at the beginning of the year. Fiscal 2023 serves as a strong foundational year as we work towards the 2020 financial and strategic targets we laid out at Investor Day, and I am excited about continuing to report on our progress. I will provide color on our outlook for fiscal 2024 in a few minutes, but first, we'll give additional details on the results for the fourth quarter. To summarize, sales declined 1% versus 2022. Operating income decreased 7%, driven by investments primarily in life sciences.
EPS of $0.78 decreased 7%, and cash conversion was 173% versus 78% a year ago. Gross margin was 34.3%, a 140 basis point improvement versus prior year. Pricing was the largest driver of the gross margin improvement, followed by benefits from the stabilization of input costs, including lower freight costs. Operating expenses as a percentage of sales were 20.0%, compared with 18.0% a year ago. The deleveraging of operating expenses in the quarter was due to increased post-pandemic hiring expenses, and importantly, nearly half of the deleveraging was from incremental expenses related to our life sciences acquisitions. Operating margin was 14.3%, down 60 basis points versus prior year, as operating expense deleveraging more than offset the year-over-year improvement in gross margin. Now I'll discuss segment profitability.
Mobile Solutions pre-tax profit margin was 16.2%, up 40 basis points year-over-year, and Industrial Solutions pre-tax profit margin was 19.2%, up 60 basis points. Gross margin expansion, driven in large part by pricing, was a key driver in both of these segments. With respect to life sciences, the pre-tax loss of approximately $7 million included a headwind from acquisitions of roughly $8 million. Pre-tax profit margin was -12.4% versus 20.3% a year ago. While incremental investments in our acquisitions, including the purchase of Univercells Technologies, are negatively impacting results in the short term, we remain committed to investing for the future and look forward to scaling these businesses. The decline in disk drive sales was also a margin headwind this quarter. Turning to a few balance sheet and cash flow statement highlights.
Fourth quarter capital expenditures, mainly inclusive of continued capacity expansion investments in North America, were approximately $25 million. As I mentioned earlier, cash conversion in the quarter was 173%, particularly strong versus 78% in 2022. We continue to experience high levels of conversion as a result of our actions to reduce inventory to more normalized levels. In terms of other capital deployment, we acquired Univercells Technologies for $147 million and returned $53 million to shareholders, inclusive of $30 million in the form of dividends and $23 million in share repurchases. Our balance sheet continues to be in great shape. This quarter, our strong cash flow generation enabled significant capital deployment with a minimal change in leverage. We ended the quarter with a net debt to EBITDA ratio of 0.8 times. Now, moving to our fiscal 2024 outlook.
First on sales. We are forecasting fiscal 2024 sales to increase between 3% and 7%. This includes pricing of approximately 2% and a currency translation benefit of about 1%. For mobile solutions, we are anticipating a sales increase of between 1% and 5%, with our first-fit businesses up low single digits and aftermarket sales up mid-single digits. Supportive end market conditions, along with market share gains and aftermarket, are expected to be the drivers. For industrial solutions, sales are expected to increase between 3% and 7%. IFS sales are forecast to rise mid-single digits from strength in virtually every business, including dust collection and industrial services. Aerospace and defense sales are projected to decline low single digits after cycling two years of strong post-pandemic growth in both fiscal 2022 and fiscal 2023.
In life sciences, we are forecasting sales to increase approximately 20% as we drive geographic expansion in food and beverage, as our bioprocessing equipment and consumables business mature and commercialize, and as the disk drive business returns to growth. In addition, we expect full year fiscal 2024 life sciences pretax profit margin to be positive and remain confident in our life sciences investor day targets. Moving on to operating margin, we expect full year operating margin within a range of between 14.7% and 15.3%. An increase versus 14.6% in fiscal 2023, driven by gross margin expansion and partially offset by higher expenses as a rate of sales. Our guidance implies an operating margin at an all-time high for Donaldson, which is important to note, particularly given our ongoing investments as we work to scale our life sciences businesses.
As I always say, we remain committed to higher levels of profitability on higher levels of sales, and we plan to deliver this again in fiscal 2024. In terms of EPS, we are forecasting a range between $3.14 and $3.30, from $3.04 in fiscal 2023. Now on to our balance sheet and cash flow outlook. Cash conversion is expected to be in the range of 95%-105%, slightly down from 114% in fiscal 2023, but still above our historical averages.
Our capital expenditures forecast is $95 million-$115 million, and while heavily weighted towards growth initiatives, includes maintenance investments such as Workplace of the Future, our initiative to update and modernize our building facilities, and our continued commitment to attract and retain talent. In terms of other capital deployment priorities, we continue to focus on reinvesting back into the company, strategic acquisitions, and our commitment to returning value to shareholders through dividends and share repurchases. Now I'll turn the call back to Tod.
Tod Carpenter (Chairman and President, and CEO)
Thanks, Scott. As we begin fiscal 2024, through each of our segments, we are steadfast in fulfilling our purpose of advancing filtration for a cleaner world. In Mobile, we are addressing a growing need, helping our customers solve sustainability challenges by delivering higher performance solutions and utilizing our technology to improve efficiencies and fuel economy.
We continue to build out our alternative power solutions portfolio to ensure we remain well positioned to address all future engine adoption scenarios. In Industrial, we are growing our technologies and solutions to form strategic customer partnerships. Our expanded connectivity applications enable monitoring and alerting, and drive energy efficiency. Our dust and fume control product portfolio, designed for optimized energy consumption and carbon footprint reduction, provides solutions for customer environmental filtration challenges.
In Life Sciences, we are building out capabilities to address process integrity in food and beverage, and improve the sustainability of the global food supply through entry into alternative proteins. We are also leveraging our existing technology, R&D capabilities, and acquisitions to support the development of new therapeutics through differentiated and disruptive technologies.
A few comments on our progress in this regard, which gives us confidence in achieving our growth objectives. We have added over 1,000 years of bioprocessing experience to our team, including 150 scientists, engineers, and commercial and operations personnel. Customer interest in our Purilogics and Isolere technology is tremendous. We are building onto a $210 million opportunity pipeline with large customers, and over 20% of this pipeline has already achieved technical approval.
Lastly, sales of Solaris bioreactor products more than doubled year-over-year in the fourth quarter, and we enter fiscal 2024 with backlogs at record highs. In closing, I look forward to the journey that lies ahead as we execute on our longer-term strategy and drive towards our financial targets, and I'm confident we have the right team in place to achieve those goals. With that, I will now turn the call back to the operator to open the line for questions.
Operator (participant)
At this time, I'd like to remind everyone, in order to ask a question, press star followed by the number one on your telephone keypad. Our first question will come from the line of Bryan Blair with Oppenheimer. Please go ahead.
Bryan Blair (Managing Director and Senior Analyst)
Thank you. Good morning, everyone.
Tod Carpenter (Chairman and President, and CEO)
Good morning.
Bryan Blair (Managing Director and Senior Analyst)
Starting with your top-line outlook, maybe offer some more color on what you're seeing in current order rates and how your team's contemplating first and second half growth by segment. There's, you know, now quite a bit of nuance there and certainly different comps that the segments face as fiscal 2024 moves forward.
Tod Carpenter (Chairman and President, and CEO)
So maybe what I'll do is, This is Tod. So maybe what I'll do is talk at the macro, and Scott could give you a little bit a feel for numbers on the cadence as you work to build your model. Just at a macro level, we see strength in Europe followed by good markets in the United States, okay markets in Latin America, and troubled markets in APAC. As you kind of look at across our businesses, clearly, the Mobile Solutions segment is experiencing destocking, largely because of the OE portion of our aftermarket business.
That is what's keeping us into the low single digits type of growth level. IFS continues to be strong, both aftermarket as well as the equipment side, and that's more of a broad-based type of comment. Within Life Sciences, we would look to continue to execute and see growth across those base businesses that we have been growing in the prior years. So as we just maybe look at the macro model, we're returning more to a more normal cadence of Donaldson Company, whereby last year we were 49% first half, 51% second half. We would expect this fiscal year to be more of a 48, 52 type of a split.
Scott Robinson (VP and CFO)
So maybe I'll just add on a little bit that to that, Brian. So, you know, in terms of quarterly sequencing, in total, you know, like Tod said, we're kind of back to normal seasonality, so that means revenues in the second half will be higher than in the first half. Also, in terms of profitability, both gross margin and operating margin, I mean, we've given you guidance for the year in total, but generally, both the gross margin and the operating margin are gonna be generally sequential up quarter-over-quarter in each of the quarters throughout the year. So it's a little bit of a ramp, this year on both gross margin and operating margin, with revenues, you know, a little bit higher in the back half than in the front half, as Tod mentioned.
So we're kind of sticking to the guidance at the whole level from a quarterly perspective. There are some pluses and minuses within each of the business units, but I think if you stick with the normal seasonality, and revenue's generally increasing, you know, first half to back half, and gross margins and operating margin generally sequentially improving in each of the quarters throughout the year.
Bryan Blair (Managing Director and Senior Analyst)
Okay. Appreciate the color there. Sticking with margin, industrial profitability was, again, actually pretty exceptional in the quarter, and industrial performance overall has been very solid. The last three quarters, you've come in well ahead of your fiscal 2026 targets for industrial margin. Seemed to have pretty good momentum, going into fiscal 2024. Are run rate margins sustainable for the segment, or are there, you know, cost, mix, other factors that we should keep in mind that may moderate profit level going forward?
Tod Carpenter (Chairman and President, and CEO)
Well, let me just start, and I'll turn it over to Scott here for a little bit more color. But just at the macro level, we're executing extremely well with our strategy on industrial. Clearly, that we talked about in Investor's Day with the connected-based products. We are seeing share gain within our aftermarket businesses. Our equipment-based businesses are hanging quite well overall at the macro atmosphere. So we're pretty comfortable with where we are, what we're seeing, and we'll continue to press and execute our strategy.
Scott Robinson (VP and CFO)
Yeah, and maybe I'll just add, Brian, you know, we, like you said, we did have very good performance, and we really had strong, project-based shipments in the last part of last year, so that really drove a very strong leverage and high profitability. So we're, you know, very pleased to see the progress and success of the organization. So we probably over-leveraged a bit, but we expect industrial margins to continue to be strong. We do think about our Investor Day targets. At this point, we've chosen not to change them. We're certainly committed to achieving all of those Investor Day targets. Kind of as you've noted, industrial has got a very good jump on achieving their operating margin targets that we laid out in Industrial Day, and is actually slightly ahead right now.
Bryan Blair (Managing Director and Senior Analyst)
Yep, absolutely. For life sciences, Scott, I think you called it last quarter, you know, 800 basis points or thereabout, margin impact from acquisitions. Sounds like that was, you know, was worse than that at, $8 million or so in dollar impact for fiscal 4Q. We know there's a lot of investment there, and it's a, you know, long-term outlook for, you know, the build-out of, of, the platform. But how should we think about, you know, the near-term progression of margin impact from, from the acquisitions, and how that is, ultimately contemplated in your, fiscal 2024 guide?
Scott Robinson (VP and CFO)
Yeah. So I mean, we certainly talked about that quite a bit, and first off, just to note, we're very proud of the fact that the company continues to put up record levels of sales and record levels of property while we are investing in our life sciences and other businesses to really make sure we secure long-term growth potential for the company.
We've done some acquisitions, and with that comes some amortization and some startup costs, and we've done some investments like that, and we wanna make sure we properly fund those businesses. I said in my script that we expect the life sciences operating margin to be positive next year. So, you know, we definitely invested heavily, and we took on a bit of a run rate expenses, and you see that in our OpEx. We do expect the operating margin for Life Sciences to be positive for next year's fiscal results.
Bryan Blair (Managing Director and Senior Analyst)
Okay, understood. Thanks again.
Operator (participant)
Your next question will come from the line of Nathan Jones with Stifel. Please go ahead.
Nathan Jones (Managing Director)
Good morning, everyone.
Tod Carpenter (Chairman and President, and CEO)
Morning, Nathan.
Brian Drab (Co-Group Head–Industrials)
Morning.
Nathan Jones (Managing Director)
I am gonna follow up on Brian's last question on the Life Sciences margin and see if we can get, you know, any more help with the progression of that through 2024. The margins swung by, you know, 30 points, from the first quarter of 2023 to the fourth quarter of 2023. Just, I know, Scott, you said positive for the year. Is there, you know, any help you can give us with-- I mean, I assume they're gonna start out negative in the first quarter. Should we be thinking about something like the fourth quarter margin in the first quarter, and how that kind of ramps up through the year to get to positive?
Tod Carpenter (Chairman and President, and CEO)
Yeah, I mean, we're looking at next year, where, you know, we definitely stepped up our investments in the fourth quarter. So as sales increase, you know, we'll certainly help cover those costs. Don't forget, we also had the disk drive headwinds this year that we expect to abate next year. You know, so we're looking at, you know, low single-digit profitability and for the most part, relatively consistent throughout the fiscal year, achieving a positive operating margin for the next year. So there's not any massive swings contemplated. You know, the really big investment period, you know, was the fourth quarter, and we had the disk drive headwinds that will normalize sequentially going forward. So we feel like we're in a better position and the results will reflect that.
Nathan Jones (Managing Director)
So the margins, you're not thinking the margins in Life Sciences have a big ramp up throughout the year. They're relatively consistent. I mean, if you're assuming volume gets sequentially better through the year, I assume margins would get sequentially better through the year, but there's not a huge variance in those numbers.
Tod Carpenter (Chairman and President, and CEO)
There's not a huge variance in the numbers, Nathan, and Life Sciences will be actually a little bit lumpy in the year, more than some of the other than the other two segments, but just slight degrees of difference throughout the year. We put out the investor day target, right, of 22.5% operating margin for Life Sciences three years out, and we're still committed to that number and believe it's achievable.
Brian Drab (Co-Group Head–Industrials)
Right.
Nathan Jones (Managing Director)
That's just that just comes from absorbing these costs with revenue as those businesses ramp up, right? I mean, you're still in a position with a number of those businesses where revenue is, you know, pretty minimal.
Tod Carpenter (Chairman and President, and CEO)
Exactly. When you look at what additional CapEx might be needed in the businesses, the way we look at that is we will need some additional manufacturing capability across the Life Sciences segment. We will have that investment within the next three years. Adding that in to be able to meet the manufacturing capabilities, but we bake that all within this guide. We put that all within the investors' targets, and gives us confidence within the targets that we talked about last April.
Nathan Jones (Managing Director)
Maybe, we could get some more color on the $210 million opportunity pipeline that you talked about, Todd. Half has achieved technical approval. I guess that means the other half is still waiting for it. Is that $210 million all business that you expect to win, or is that business that you still have to compete to win? How should we think about that, kind of those projects being released and ramping up?
Tod Carpenter (Chairman and President, and CEO)
The $210 million is the opportunity pipeline, and that's why we pointed out that where 20% of it is approved, right? Eighty percent of it, we are still looking to go through with the particular OE the approval process, or we are in flight of the approval process. But that's near term what we're chasing, and we've looked at that $210 million over a seven-year period. It's important to also understand that what we've baked into this particular guide out of those seed planting-based businesses is very little revenue for this fiscal year. It really starts to show a bit more next year and then ramps up.
Nathan Jones (Managing Director)
Great. Thanks for taking my questions. I'll pass it along.
Operator (participant)
Your next question comes from the line of Brian Drab with William Blair. Please go ahead.
Brian Drab (Co-Group Head–Industrials)
Hi, good morning. Thanks for taking my questions. The Univercells acquisition, I was just curious, you know, that was $10 million in revenue in 2022. You know, you paid a good multiple for that. I think it's like 13.5x trailing sales, so I assume that's growing rapidly. What should we model in for that business doing roughly for fiscal 2024? It must be in the like, I guess, like $15 million range or some thereabout.
Tod Carpenter (Chairman and President, and CEO)
Yeah, we, you know, we baked that into the current guide that we gave you, obviously, with what our expectation--with what our expectations are. We do expect it to grow double digits within that business. But we also have some pieces to put in place in order to be able to execute that, which we have all put in on the revenue side, as well as any particular cost on that into this guide that we just gave you. Remembering that, we have not owned that business very long, so we'll be integrating it throughout this year.
Brian Drab (Co-Group Head–Industrials)
Yeah. Okay, got it. Makes sense. So with the 20% forecast for the Life Sciences segment, you know, I, I guess maybe like, you know... I, I'm going to probably model, like, you know, like 15% organic revenue growth. I'm just wondering: can, can you, you know, should I discern anything from the press release in, in terms of the order that you listed the, the drivers of growth in Life Sciences? Because you know, food and beverage, bioprocessing, then disk drive. I'm just wondering if, like, which of those is expected to contribute most of the incremental organic revenue in, in fiscal 2024, which of those-segments or in the right order?
Tod Carpenter (Chairman and President, and CEO)
Yeah, it's gonna be broad-based, Brian, but, you're right. We've grown the food and beverage business double digits for a number of years. We expect that to happen again this year. Of course, we noted that our Solaris backlogs are at all-time highs. We would have expected that. That just is a good indicator to you that we're executing quite well. We would expect disk drive coming off easier comps to have a low double digit type of a growth rate. So, you know, you pack all that together, that's how... That's what really gives us confidence in the numbers we're giving.
Brian Drab (Co-Group Head–Industrials)
Okay, got it. Thanks. Just one last one. Can you talk about, you know, customer development within the, in, like, acquisition progress that you're making with customers within the life sciences segment? You know, how many customers do you have now? Like, that Solaris backlog, is that across many different customers, or is it one big project for one customer? Any color on that would be really helpful. Thanks.
Tod Carpenter (Chairman and President, and CEO)
Yeah. Thanks, Brian. So it, it's not one big project. It is more broad-based. Remember that Solaris makes the very small desktop type of bioreactors that would go into laboratory type of use, as well as the larger project type of bioreactors that you're referring to. Their backlog is a bit more broad-based than one big elephant, so to speak. So, so we're, we're happy with with the progress that we have there. With the newer acquisitions, we're also happy with the very, very broad-based customer acceptance of those, of those particular products and are working with a number of of opportunities.
Brian Drab (Co-Group Head–Industrials)
Okay. Thanks, Tod.
Operator (participant)
Your next question comes from the line of Laurence Alexander with Jefferies. Please go ahead.
Kevin Estock (VP and Equity Research)
Hi, good morning. This is Kevin Estok on for Laurence. So my questions have largely already been asked, but I guess just, do you guys see any risk of a recession impacting any of your end markets in 2024? I guess, if so, which areas would be most at risk? When you said that you expect your top line in APAC to be troubled next year, is that mostly related to China, or, you know, are there issues elsewhere in the region that you're seeing?
Tod Carpenter (Chairman and President, and CEO)
Yeah. So when you talk about the recession, it's really China, for us, all the time. You know, we're really happy, with where we are with China, based upon... We know that that's a, a very troubled economy over there. Everybody knows that in the world. But we're happy with where we sit, positioned to when it comes out, that should give us tailwind. We have a, a number of different market share gains over there, that, that should be able to, give us some positive outcomes. However, we have not, baked any of that type of lift into, into F '24 guidance. We believe that it'll just be a bit more protracted than, than it's currently or than was, let's say, seemed six months ago.
So we're very careful about projecting China, but for the rest of the world, we have not really seen any early indicators of recessionary type of behavior in any of the other geographies. So we have not contemplated that at this time.
Kevin Estock (VP and Equity Research)
Okay. Thank you.
Operator (participant)
Your next question comes from the line of Rob Mason with Baird. Please go ahead.

Yes, good morning. Maybe, Tod, just wanted to follow up on that last comment. I mean, to the extent that, you've not baked in any recessionary impact, I guess, how do you reconcile some of the, you know, the PMIs that we see out of Europe versus your results, which seem to be very good? It just seems like there's some disconnect there, given the results. Is that more share gain oriented, on your side? Or just, you know, kind of help us versus what we, you know, historically would have expected, you know, given those macro indices.
Tod Carpenter (Chairman and President, and CEO)
Sure. So we've long said that we're a diverse portfolio of businesses across our company. You're starting to see the strength of that, particularly, as you read about particular sectors having some headwinds. Donaldson Company is more broad than that. Some of the execution within the strategies that we talked about Investors Day is actually going extremely well. We clearly have share gains in some of our replacement part-based businesses. So we have good momentum at this point in time, and we'll continue to press, continue to invest, and look for a continuation of the solid execution that we're seeing across our company.
Rob Mason (Senior Research Analyst)
Yep. To the extent, in speaking to the mobile business, I think, particularly, to the extent destocking was heavy in the fourth quarter, it's, it's been going on for several quarters. I thought your commentary around the aftermarket, mobile aftermarket business implied that it may continue, and I was just curious if that's the case. You said it could weigh on the low single digit or influence that low single digit growth rate. You know, how much longer do you think are you anticipating that destocking headwinds impact that business?
Tod Carpenter (Chairman and President, and CEO)
Yeah. Yeah, thanks, Rob. Let me just give a little bit more specific color on that. If you recall in our mobile solutions aftermarket business, our OE portion of that business is 40% of the revenue. Our independent channel is 60% of the revenue. If you look at just the fourth quarter, we would tell you that our independent channel was roughly flat year-over-year, and the OE channel was down mid-teens. So that suggests to you that the destocking across the OE channel, and it's not specific to one end market, but now has more broadened to multiple customers, it has really created the headwind across our aftermarket. It is not the independent distributor channels.
In fact, looking forward, we would expect that destocking from all the behaviors we've seen, from the OE, to pick up just a little bit, looking forward here, in the first two quarters, but not appreciably. So therefore, our estimation is that the destocking at the OE side would go in the first Q and likely the second quarter, because there's a lot of balance sheet management across the OE sector in our second quarter as we end the calendar year, and then pick up in the second half of the year.
Rob Mason (Senior Research Analyst)
Yep. Maybe just to take the other side of that, the First-Fit side in mobile. Now the supply chains have largely normalized, lead times have come down. Are your OE customers still giving you the same level of visibility on their production schedules, or is that, you know, is that shortened up as well? How do you feel about the level of visibility on that side?
Tod Carpenter (Chairman and President, and CEO)
So nothing's changed. Yeah, nothing's changed about the models between our the way we operate with our OEs and balancing companies. We do things where our computers are linked, and so we get a longer look at their production build rates. They may firm the build rates a little tighter. So say at more like 90 days rather than 150 days. But we're still very comfortable with what we're seeing across all of the end markets in the mobile solution. So that's agriculture, construction, mining, and on-road. With on-road likely showing a bit more resiliency than the others.
Rob Mason (Senior Research Analyst)
Very good. I'll pop back in the queue. Thank you.
Operator (participant)
Again, that is star one to ask a question. We have no further questions at this time. I'll turn the call back over to Tod Carpenter for any closing remarks.
Tod Carpenter (Chairman and President, and CEO)
That concludes the call today. Thanks to everyone who participated, and I look forward to reporting our first quarter fiscal 2024 results in November. Have a great day. Goodbye.
Operator (participant)
That will conclude today's call. We thank you all for joining. You may now disconnect.
