Earnings Call Analysis

Waters Corporation Posts Strong Q2, Adjusts 2024 Outlook

Waters Corporation reported strong Q2 results, surpassing both top and bottom-line guidance. Despite a 4% sales decline, operational resilience and strategic initiatives led to a non-GAAP EPS of $2.63. Notably, the company's M&A activities, especially the Wyatt acquisition, contributed positively. However, due to cautious market conditions and China's uneven recovery, Waters revised its 2024 sales guidance to a range of -2.2% to -0.7% growth in reported sales. Looking forward, the company anticipates gradual improvement, backed by a competitive portfolio and strong customer demand, expecting an adjusted EPS range of $11.55 to $11.65 for the full year.

Introduction and Thank You

The company achieved strong results in the second quarter, surpassing both its top line and bottom line guidance. This was attributed to commercial execution, operational management, and innovation, which collectively enabled differentiated performance and the benefits of pioneering science. A notable improvement was observed in customer spending throughout the quarter, with a significant surge in June.

Sales and Revenue Trends

Sales saw a decline of 4% both as reported and in organic constant currency terms. Non-GAAP earnings per share stood at $2.63 while GAAP EPS was $2.40. Excluding China, sales showed low single-digit declines, with customer capital expenditure (CapEx) spending showing initial signs of improvement. In China, sales declined in the low teens but performed better than expected. Improved growth rates were observed across pharma and industrial sectors compared to the previous quarter.

Operational Performance and Margins

Gross margins remained flat at 59.3%, and adjusted operating margins were solid at 29.2%. Despite facing volume, foreign exchange (FX), and inflationary challenges, the company counteracted these effectively through robust operational management. Looking forward, the company foresees further long-term margin expansion driven by strategic and operational initiatives.

New Product Launches and Innovations

Several new products were launched, including the Xevo MRT, a high-performing benchtop mass spectrometer, and the Acquity QDa mass detector, an enhanced version of a best-selling analytical instrument. These products are designed to meet critical customer needs and contribute significantly to the performance and competitive edge of the company in the market.

Financial Health and Free Cash Flow

Free cash flow for the second quarter was $143 million after funding $36 million in capital expenditures. Year-to-date free cash flow amounted to $377 million, representing 28% of sales. The company maintained a robust balance sheet with $1.7 billion in net debt, equating to a net debt-to-EBITDA ratio of approximately 1.7x.

Guidance Update

The company revised its full-year 2024 sales guidance to account for a more gradual improvement in the second half of the year. The updated guidance predicts a decline in organic constant currency sales growth between -2% and -0.5%. Full-year guidance for reported sales growth is in the range of -2.2% to -0.7%. Non-GAAP earnings per fully diluted share are expected to be between $11.55 and $11.65, considering a 3% headwind due to unfavorable foreign exchange rates.

Geographical Performance

Sales in Asia declined by 3%, while the Americas and Europe saw a 7% decline each. By products and services, instruments declined by 17% whereas chemistry and service revenue grew by 5%. The growth in certain geographies was attributed to improved customer activity and new product offerings.

Environmental and Sustainability Achievements

The company became the first liquid chromatography column provider to receive the ACT Ecolabel Certification from My Green Lab. This certification applies to over 40 LC columns, making it easier for scientists and procurement professionals to choose sustainable lab products. This achievement underscores the company's commitment to environmental, social, and governance (ESG) initiatives.

[Operator]

Good morning. Welcome to the Waters Corporation Second Quarter 2024 Financial Results Conference Call. [Operator Instructions] This call is being recorded. If anyone has objections, please disconnect at this time. It is now my pleasure to turn the call over to Mr. Caspar Tudor, Head of Investor Relations. Please go ahead, sir.

[Caspar Tudor, executive]

Thank you, Brad. Good morning, everyone, and welcome to the Waters Corporation Second Quarter Earnings Call. Today, I'm joined by Dr. Udit Batra, Water's President and Chief Executive Officer; and Amol Chaubal, Water's Senior Vice President and Chief Financial Officer.

Finally, we do not intend to update our guidance, predictions or projections, except as part of a regularly scheduled earnings release or as otherwise required by law. Now I'll hand over to Udit to deliver our key remarks. Following that, Amol will present a more detailed review of our results and guidance, after we'll open up the phone lines for questions. Over to you, Udit.

[Udit Batra, executive]

Thank you, Caspar, and good morning, everyone. We achieved strong results in the second quarter that exceeded both our top line and bottom line reported guidance. I want to begin today's call by thanking my colleagues for their dedication to commercial execution, operational management and innovation. This enables us to deliver differentiated performance and accelerate the benefits of pioneering science.

In the quarter, year-over-year organic constant currency sales were 500 basis points better than Q1 levels. We saw a steady improvement in customer spending throughout the quarter with a strong finish in June. Orders outpaced sales for the quarter as we built good momentum for the second half of the year. We again delivered resilient operational results with earnings surpassing our expectations. This reflects the strength of our downstream business model, progress on our strategic and operational initiatives and our indomitable spirit.

We also continued our steady stream of new product launches, releasing further innovations that address key customer needs. Waters now has a highly competitive portfolio serving attractive end markets. We expect this benefit -- we expect this to benefit us as the market recovers and the instrument replacement cycle picks up pace.

We continue to build the Waters of the future, I would like to welcome Rob Carpio, who has joined us as the new Head of the Waters Division. Rob is a talented leader and a seasoned operator with a record of delivering strong financial results and transformation in life sciences. With his appointment, he will further enhance Waters' performance and a long-term growth strategy.

Turning now to our results. In the second quarter, sales declined 4% as reported and 4% in organic constant currency. Our non-GAAP earnings per share was $2.63. On a GAAP basis, EPS was $2.40. Excluding China, sales declined in low single digits. Growth was consistent with our expectations across each of our end markets. Customer CapEx spending is showing early signs of improvement.

In China, sales declined in the low teens, which was better than expected. Growth rates improved in all end markets compared to the previous quarter, especially in pharma and in industrial. While the stimulus measures announced by the Chinese government this year are still in the early stages of implementation. We are having active conversations with customers who stand to benefit from these initiatives.

So far, this has led to improved quoting and funnel trends in the region. These opportunities are expected to begin converting to orders in 2025. Overall, instruments declined 17% and recurring revenue grew 5%. Wyatt delivered a 2% M&A contribution to sales, which was better than expected. It marks a strong close to the first year following the acquisition, where synergies were delivered well ahead of schedule. Wyatt operates in high-growth markets serving large molecule applications, especially across cell, gene and RNA therapies. Altogether, it should deliver 40 basis points of annualized accretion to the total company growth in the near to midterm.

Now I will talk about our operational performance. Margins remained resilient as we again successfully counteracted volume, FX and inflationary headwinds with solid operational management. Our gross margin for the quarter was flat at 59.3% and our adjusted operating margin was solid at 29.2%. Even with recent progress, our work is far from over. We have runway towards further long-term margin expansion driven by our strategic and operational initiatives. This includes areas such as productivity enhancement where we have various programs that are still in the early stages.

At the same time, our focus on pricing continues to yield contribution that is well ahead of historical levels. Looking forward, we feel very good about our future margin opportunity given our recent success in preserving and expanding our margins during challenging business conditions. Beyond 2024 levels, we expect to deliver a more pronounced impact on our long-term margin performance, particularly when more typical volume leverage returns.

In the second quarter, we launched a steady stream of new products, solving the unmet needs of our customers. At ASMS in June, we unveiled the Xevo MRT, which is now our highest performing Benchtop Mass Spectrometer.

It builds on the multi reflecting time-of-flight technology pioneered by the Select Series MRT, which has greater throughput and a more compact form factor. With up to 6x greater resolution and 2x better mass accuracy than competitive systems, the Xevo MRT sets new industry standards for high resolution at blazingly fast speeds. So far, our customers have been impressed by its capabilities. It will serve discovery and other upstream pharma workflows where it will accelerate R&D times for new drugs.

This includes areas such as metabolite identification where resolution, accuracy and speed are all critical value drivers. We also launched the latest evolution of our Acquity QDa mass detector, one of our all-time best-selling analytical instruments. The QDa II provides a 20% enhancement in mass range, which benefits routine identification and analysis of large molecules. It also has excellent green credentials consuming up to 70% less energy than competing products. This is a benefit of increased importance to our customers.

Most importantly, the QDa II runs on Empower, which allows for seamless regulatory submission of compliance-related data for large molecules. As we look ahead, Waters is well positioned in attractive markets with secular growth drivers where testing volume plays a pivotal role in driving long-term growth. Our full ecosystem of instruments, informatics, advanced chemistry and leading service positions us very well to help ensure the safety of medicine, food and water and batteries in electric vehicles. Along with our business model, the regulated and recurring nature of these applications results in excellent profitability and free cash flow generation.

In recent years, we've made meaningful progress in aligning Waters with faster-growing large molecule applications. Now over 1/3 of our pharma revenues comes from large molecules and novel modalities. At the same time, future testing volume is expected to grow faster than historical levels with increased prescription volumes, including GLP-1s and areas such as PFAS testing. With our revitalized portfolio, we are in an excellent position to capitalize on these growth opportunities. Over the past several years, we've launched multiple innovative new products that have enhanced our competitive edge and created better pricing levers.

Serving our core -- our next-generation LC platform, Alliance iS serves routine QA/QC analysis for both large and small molecule workflows where innovation helps drive -- helps to drive instrument replacement. It also includes our Xevo TQ Absolute mass spectrometer, which is seeing rapid growth in areas such as PFAS testing. Within our high-growth adjacencies, we've launched new products into bioanalytical characterization, battery testing and clinical applications, all of which are gaining traction given the critical unmet needs that they solve.

Finally, recent deferral of routine instrument replacement has created a catch-up opportunities -- catch-up opportunity that lies ahead of us. Weak macroeconomic conditions have put temporary constraints on customer CapEx spending for downstream instrumentation.

Historically, this dynamic has lasted for 4 to 7 quarters and has been followed by a catch up. Looking at the facts, while no two macro environments are the same, Q2 marks the seventh consecutive quarter of LC instrument decline. Expected instrument growth for 2024 equates to a 1% CAGR versus 2019 levels. This is significantly below the 5% long-term average growth rate. Improving funnel trends are a positive leading indicator that we are approaching the early innings of a recovery and initiation of a new replacement cycle.

I will now cover our 2024 full year guidance. While customer activity is showing signs of recovery, we're adding caution to our guide. Accordingly, we are revising our full year 2024 sales guidance to assume a more gradual pace of improvement in the second half of the year. As a result, our revised full year organic growth constant currency sales guidance is negative 2% to negative 0.5%. With our commitment to excellent operational performance, we expect to build leverage in our P&L and deliver an adjusted operating margin of around 31%. Therefore, our updated adjusted EPS guidance is in the range of $11.55 to $11.65.

Now I will pass the call over to Amol to continue covering our financial results in more detail and to provide further guidance -- further details on our guidance. Amol?

[Amol Chaubal, executive]

Thank you, Udit, and good morning, everyone. In the second quarter, sales exceeded our guidance range on a reported basis, declining 4%. Organic constant currency sales also declined 4%, which was a 5% improvement in growth compared with Q1 levels. We saw a steady improvement in customer spending throughout the quarter with orders outpacing sales. M&A contributed 2% to sales covering Wyatt results in the first 1.5 months of the quarter. This was better than expected as we were able to accelerate revenue synergies as part of our integration. We are pleased that within the first year of the acquisition, Wyatt is already EPS and margin accretive and our M&A execution remains well on track.

Overall, FX was a 2% headwind to the second quarter sales. In organic constant currency terms, by end market, Pharma declined 4%, Industrial declined 4% and Academic and Government declined 16%. In Pharma, sales excluding China declined low single digits, while in China, sales declined low double digits. In both cases, this reflects an improvement in growth rates compared to the previous quarter. In Industrial, sales declined 1% outside of China, led by low single-digit growth in the Americas. We again saw strong growth globally for PFAS-related applications, which has been a consistent tailwind for environmental testing.

In China, sales declined low double digits, which was also an improvement in growth rates compared to the previous quarter. For our TA division, sales were flat, driven by improvement in segments such as electronics, advanced materials and chemicals. In Academic and Government, growth remained weak as stimulus in China and elevated global funding drove lumpy spending patterns and a tough 21% comparison in the prior year's quarter.

By geography, sales in Asia declined 3%, while sales in Americas and Europe both declined 7%. By products and services, instruments declined 17%. Chemistry and service both grew 5%. There was no change in the number of days versus the prior year quarter. Our commercial initiatives continue to support robust recurring revenue growth despite ongoing headwinds from China. Within our service business, we have already achieved our goal of increasing service plan attachment by a further 100 basis points this year with service planned revenue growing high single digits in the quarter.

We are now targeting an additional 50 to 100 basis points of service plan attachment over the remainder of the year. Now I will comment on our second quarter non-GAAP financial performance versus the prior year. Despite headwinds from lower sales volume, FX and inflation, our team continued to respond to these challenges with resilience and commitment. Our focus on operational excellence with pricing, productivity and prudent spend management allowed us to deliver a resilient margin performance in the quarter. Gross margin was flat at 59.3% and our second quarter adjusted operating margin was 29.2% as expected.

Excluding FX, both gross margin and adjusted operating margin expanded 40 basis points year-over-year. Our effective operating tax rate for the quarter was 16.5%, and our average share count was 59.5 million shares. Our non-GAAP earnings per fully diluted share was $2.63. On a GAAP basis, earnings per fully diluted share was $2.40. A reconciliation of our GAAP to non-GAAP earnings is attached in this morning's press release and in the appendix of our earnings call presentation.

Turning now to free cash flow, capital deployment and our balance sheet. We define free cash flow as cash from operations, less capital expenditures and excludes special items.

In the second quarter of 2024, free cash flow was $143 million after funding $36 million of capital expenditures. On a year-to-date basis, free cash flow is $377 million or 28% of sales resulting in free cash flow to adjusted net income conversion ratio of 131%. We maintain a strong balance sheet, access to liquidity and a well-structured debt maturity profile. This strength allows us to prioritize investing in growth. We continue to evaluate M&A opportunities that will enhance value creation for our shareholders.

In the second quarter, we continued to delever while paying out this year's tax reform payment of $96 million and other items totaling $30 million. As expected, at the end of the quarter, our net debt position was approximately $1.7 billion which is a net debt-to-EBITDA ratio of about 1.7x. As we continue to delever our balance sheet, we will evaluate the resumption of our share repurchase program throughout the remainder of the year.

Now I would like to share further commentary on our full year outlook and provide you with our guidance for the third quarter. While business conditions showed signs of recovery in the second quarter, we are adding caution to our guidance. As a result, we are revising our full year 2024 sales guidance to assume a more gradual pace of improvement in the second half of the year. Our updated guidance assumes relatively flat quarter-over-quarter revenue progression in Q3 versus Q2. It also implies a weaker than typical budget flush dynamics in the fourth quarter.

Despite the added caution, we are still expecting the business to return to growth in the second half of the year. Given these dynamics, our revised full year 2024 guidance is for organic constant currency sales growth between negative 2% and negative 0.5%. At current exchange rates, we anticipate that currency translation will negatively impact full year sales by approximately 1.5%. Meanwhile, M&A contribution from Wyatt transaction has added 1.3% to our full year from inorganic sales incurred in the first 4.5 months of the year.

Therefore, our total full year 2024 reported sales growth guidance is in the range of negative 2.2% to negative 0.7%. With our commitment to excellent operational performance, we expect to build leverage in our P&L, even with the reduction in our guide. Consistent with our previous guidance, gross margin for the full year is expected to be approximately 59.8%, which is 20 basis points of expansion versus 2023. Our adjusted operating margin is expected to be around 31%. Below the line, we expect full year net interest expense to be approximately $77 million.

Our full year tax rate is expected to be 16.3% and our average diluted 2024 share count is expected to be approximately 59.4 million. Rolling all this together, on a non-GAAP basis, our full year revised 2024 earnings per fully diluted share guidance is projected in the range of $11.55 to $11.65 and includes an estimated headwind of approximately 3% due to unfavorable foreign exchange.

Looking to the third quarter of 2024, we anticipate that customer spending will remain cautious, but show further signs of recovery. We expect an improvement in year-over-year growth compared to that in the second quarter as previous year comparisons, particularly in China become easier and has continued improvement in funnel activity translates to orders. Given these dynamics, our third quarter organic constant currency sales growth guidance is projected in the range of positive 1% to positive 3%.

At current rates, currency translation is expected to subtract approximately 1.5%. Therefore, our third quarter reported sales growth guidance is negative 0.5% to positive 1.5%.

Based on these revenue expectations, third quarter non-GAAP earnings per fully diluted share are estimated to be in the range of $2.60 to $2.70, which includes a negative currency impact of approximately 2 percentage points at current FX rates. Now I would like to turn the call back to Udit for our closing comments. Udit?

[Udit Batra, executive]

Thank you, Amol. So now to summarize, with our strong commercial execution and continued resilient operational performance, our second quarter results demonstrate Waters' ability to deliver solid results in various market conditions. We're positioned well for the future with a long-term outlook that is above our historical growth rate of 6% as global testing volume growth remains on track and customer CapEx spending continues to recover.

I am also proud of what our team has continued to accomplish on ESG and sustainability. Last month, we announced that Waters has become the first liquid chromatography column provider to receive the ACT Ecolabel Certification from My Green Lab. This designation applies to more than 40 of our LC columns and makes it easier for scientists and procurement professionals to choose more sustainable lab products. So with that, I will now turn the call back over to Caspar.

[Caspar Tudor, executive]

Thanks, Udit. That concludes our formal comments. We are now ready to open the phone lines for questions.

[Operator]

[Operator Instructions] Your first question for today will come from Vijay Kumar of Evercore ISI.

[Vijay Kumar, analyst]

One maybe high level on your comments about the progression in the quarter, a strong finish to June, orders above revenues. Help us square what the guidance change, right? I don't think the guide change was a surprise. Is this just a conservatism in light of the strong June finish order momentum commentary? Or how should we input that in light of the guide change?

[Udit Batra, executive]

First, thank you for the question. I think you sort of answered your own question. We just sort of taking first just a step back and a 10,000-foot view. I mean our approach to guidance, Vijay has not changed as we progressed through quarter-on-quarter, right? So we look at 3 different things. We, of course, look at the facts from the funnel, how the quarter is progressing, how it's ending, then we spend a lot of time looking at history. I mean, there's not that many businesses that have 20 years of data on instruments quarter-on-quarter. So we look at that.

And the third thing we do is we talk to our customers and see what the sentiment is, how the orders are progressing, how the sales are progressing. So just to take you through that, and sorry for the long answer, but it will give you context on our philosophy and the guide. So on the fact, you're totally right. We saw -- we've seen progressive improvement from Q1 to Q2. Sales have declined less in Q2 versus Q1. And as Q2 progressed, I mean, as you will know, June is a big month for us, we saw significant momentum in June. You'll remember, in March, we talked about orders and quality of orders. And we said we'll start to see them convert into sales towards the end of Q2.

Exactly -- that's exactly what happened. Lot of sales momentum at the end of the quarter in June and equally, orders growing even faster than sales. So we feel very good about where we see the funnels and what we see with the facts. Now historically, when you look at Waters' business, we have the benefit of, as I said, 20 years of data, especially LC, if you just look at the LC business, when it goes through trough, it is usually between 4 to 7 quarters of negative growth.

And Q2 was the seventh quarter of negative growth. So we are poised for a recovery and we're operating at -- if you just look at Q2 on a 5-year CAGR basis, it's minus 2%. And we're seeing signs of recovery in LC. So we've factored that into our thinking. And then finally, talking to customers, both of those factual pieces of evidence are verified. I spent a lot of time in the quarter in Europe and in the U.S. with large pharma customers, in particular in China is improving.

So as we look at the second half of the year, we're expecting to see improvement quarter-on-quarter as we go from one quarter to the other. The second half will see growth, as you rightly pointed out, we've just taken our guidance down, especially in the fourth quarter to assume a slightly lower ramp than we would see historically. So just a little bit of caution built into it. I think on a constant currency basis, it's not more than $50 million. So there's a bit of caution built into what we're seeing. And as more data emerges, you'll see us correct that. Sorry for the long answer, but I know -- I'm sure many people have the same question.

[Vijay Kumar, analyst]

No, that's helpful. And if I understand you, what you're saying is, look, we're not seeing anything in the quarter. It's positive trends in the right direction. But from a guidance perspective, you're just derisking it. And it's more from the perspective of being conservative versus having seen anything in the quarter. Is that a fair summary?

[Udit Batra, executive]

Yes.

[Vijay Kumar, analyst]

Fantastic. Revenues, I think, were cut maybe 3% below street the implied Q4 dollar revenues. EPS roughly in line with -- the Street. So what changed is the implied operating margins coming in better? Is there any below-the-line contribution that's driving Q4 EPS?

[Amol Chaubal, executive]

Yes. Look, I mean, as you've seen us through last year and this year also back in '22 against inflationary pressures. Our team is super resilient, and we are able to defend margin and even during down volume cycles, we're able to expand margin. As we've discussed before, we have a set of productivity initiatives that have a very long runway, and we are able to accelerate some of them. And that reflects in sort of how we've been able to expand margin even last year.

If you look at the embedded implied margin profile in our guide. Our second half margin is relatively flat versus last year. So there is not any meaningful step-up in the second half versus prior year. The only thing is as we've sort of taken a more cautionary view on the guide, we will see some of the actions that we've put in place already show up in Q4, and that will help us a little bit in Q4. But other than that second half is relatively flat versus last year.

[Operator]

The next question will come from Dan Brennan of TD Cowen.

[Daniel Brennan, analyst]

Maybe just on instruments. Q2 was about in line, right, with what your guide expected down 17%. I think you were down mid-teens. Can you just flush out a little bit LC versus MS? And how are we thinking about the updated instrument outlook for the back half of the year? And kind of what's the math to support that.

[Udit Batra, executive]

So let me start and Amol can jump in, Dan. So instruments declined about 17% in the quarter. LC was a bit modest than that, mid-teens. Mass spec declined a bit more, and TA was around minus 2%, so minus 17% in the quarter. As I mentioned earlier, we're seeing steady improvement as we went through the quarter and the funnels look extremely strong, especially on the LC front. So for the back half of the year, we're assuming that the instrument growth rate would be flat versus the previous year.

So overall, second half is flat. And just to sort of go a bit beyond the numbers, and now as I mentioned earlier, the LC replacement cycle now is in the seventh quarter of its decline, we're starting to see across the globe customers initiating their replacement cycle.

So we expect that to -- we expect a little bit of decline or flat growth in Q3 for LC, but in Q4, we expect the replacement cycle start to kick in, which is consistent with what we see with the funnels. So quite an exciting time just given the renewed portfolio across all the instruments as a replacement cycle begins, we feel very good about where we are sitting today.

[Daniel Brennan, analyst]

Great. And then just China, anything changed with the guide there you were down I think mid-teens kind of in the quarter around what the guide was. And now what are you assuming for the full year? And is the commentary that orders on the kind of stimulus will start in '25? Is that a bit of a push? Like I think I thought I heard you guys say previously maybe orders come back half and then it kind of kicks in '25. Any color on back at our China and then how we think about stimulus impact?

[Udit Batra, executive]

Sure. Firstly, I mean, China came in ahead of expectations, right? I mean that's part of the driver for the beat. I mean just to give you a bit of the facts, I mean, Q1, China declined 26%. In Q2, it was around 10% decline. And I mean, in the largest end market pharma, we went again from about a 25%, 26% decline to what a 10% decline in Q2. So steady improvement in China in the second half of the year has a lower base, but we've kept the full year guide at a low double-digit decline for China, just to sort of watch and see more data. So good things happening in China.

And again, when you compare LC growth rate, and this is sort of an interesting fact -- for the first time in a very long time, China's LC decline was less than the rest of the world, right? So China declined in the high single digits, whereas the overall decline for LC was a bit higher than that. Now as you think of the stimulus, nothing has really changed versus previous commentary. We're spending a lot of time with customers, doing three things.

One, helping them identify the age of instruments. You recall this particular stimulus is targeted towards instrument replacements, the age of the instruments, their visibility for the stimulus and helping them do the paperwork as they start to submit applications for funding. We think this is going to be -- this is going to impact growth only in 2025, maybe a modest impact towards the end of the year, but would not factor that in.

[Operator]

The next question will come from Tycho Peterson of Jefferies.

[Tycho Peterson, analyst]

Maybe just diving in a little bit into the guidance in the back half of the year. So you're guiding to revenues up sequentially from 2Q that's kind of out of line with normal seasonality. So maybe just touch on visibility? And then for the fourth quarter, your -- I think in plant operating margins are mid-to-high 30s to hit EPS guide. I know you said operating margins are flat in the back half of the year. But what drives that fourth quarter ramp in particular? That seems that in line with normal seasonality?

[Amol Chaubal, executive]

Yes. So I mean, look, Q-on-Q, Q2 to Q3 is relatively flat. If you look at last 10 years, it has sort of oscillated between plus and minus 3%, right? So it's sort of within the range. And what gives us comfort and confidence on that is what we have in our funnel and the activity that is progressing as well as the fact that we built some backlog in Q2. So that also helps.

Going to your other question around second half margins. As I said, second half margins are relatively flat versus last year. There's a small difference between Q3 and Q4, one is the prudence in Q3, the second piece is, as we've sort of taken a more cautionary view on the guide, we've put in place certain cost measures that are already playing out particularly around outside services spend, particularly around how we resource certain growth initiatives.

And you will start to see some of that impact flow through more in Q4 than in Q3. So there is some plus/minus between Q3, Q4, but overall, second half operating margins are relatively flat versus last year.

[Tycho Peterson, analyst]

Okay. And then the follow-up, Academics is only 10% of the mix, I know, but it was down 16%. Can you maybe just talk on how much of that was U.S. versus Europe? And what are you thinking back half of the year as the comps ease there for Academic?

[Udit Batra, executive]

I think no change in assumption on the Academic side. It's such a small portion of our business, Tycho. So really no change from the previous assumptions.

[Amol Chaubal, executive]

Yes. And I mean you look at it this way, right, like first half of last year, was super well funded between the China stimulus and what was happening in U.S. and Europe. If you look at it on a 2-year stack basis, pretty much every quarter you will see is like 0.1% growth.

[Operator]

The next question comes from Matt Sykes of Goldman Sachs.

[Matthew Sykes, analyst]

Maybe just first, you guys have leaned into the CDMO channel in China over the past couple of years and that's been in an area of weakness recently due to overcapacity. Could you maybe kind of talk about what you're seeing in the CDMO channel in China? And is it part of sort of some of the inflection that you see maybe towards the back half of this year into next year? Or is that going to remain fairly subdued for the balance of this year and into '25.

[Udit Batra, executive]

Matt, thank you for the question. I think we were -- we gave a lot of details around this time and probably even earlier than that last year on CDMOs in China in particular. So really no change from what we saw last quarter, steady improvement on the recurring side as activity starts to pick up a bit from a very low base, right? You'll recall, it's an extremely low base now but CapEx is still subdued. And we have not assumed any improvement in CapEx in the CDMO segment.

Now overall, the generics market in pharma in China is starting to get a bit better. I mean this is why we exceeded our growth -- in growth expectations in Q1 and now in Q2. So steady improvement in China as you go through the year. Especially on the LC side, we're starting to see some replacement cycles get initiated there. So CDMO less, but generics a bit more starting to see life there.

[Matthew Sykes, analyst]

Got it. And then Amol, just on margins, you discussed sort of back half and your expectations. I'm just wondering on a longer-term basis. You made some pretty positive commentary about some margin -- longer-term margin drivers. Going forward, how should we think about operating margin cadence over the longer term for the business? And where are some of the levers to kind of continue to expand those margins as we move through '25 or maybe on a longer-term framework?

[Amol Chaubal, executive]

Thanks, Matt, for the question. And look, I mean, there are sort of 3 to 4 broad levers here. One is, our business is structured such that if we grow more than 5%, it produces 50 basis points of volume leverage. And that volume leverage largely shows up on the SG&A line versus on the gross margin line.

Two, we have benefit from mix as we move to more recurring as well as with the discipline that we've put in pricing, we feel comfortable like we've seen even in these challenging market situations that we are able to do a little more than 100 basis points better than what we've historically done on pricing. And so mix and pricing sort of is accretive to our margin profile. And then a couple of years ago, we started various productivity and operational excellence initiatives that have started bearing fruit, right?

Things like procurement excellence, operational excellence in manufacturing, setting up GCC in India, and these initiatives have a long runway. I mean, between these initiatives, we expect to cover approximately 300 basis points over a course of about 8 years, right? So they add up to the profile. So overall, our goal is between the 3 vectors to put about 100 basis points of margin expansion on the board and use about 70 to 80 basis points from these gains to fund higher growth adjacencies.

And then as we get into 6, 7, 8th year, when some of these productivity initiatives will start to saturate, we expect these higher growth adjacencies to start to produce one revenue growth and two, margin accretion, and that will then sort of take over the impact of that productivity initiatives have saturated.

Now as we've gone through last couple of years where the volume leverage was not there, in fact, was a headwind. Our teams were able to accelerate some of the benefits on these productivity initiatives as well as we took proactive cost actions and got benefit from pricing, which have allowed us to not just defend margin, but also expand margin during down volume cycles.

And that's where the difference lies, right? Because people look at it and say, last 10 years, Waters margin has been always sticky at 30%. And so where was the volume leverage. And the answer to that is there was always a volume leverage, but we gave it up in a down cycle. And this time around, we like -- we're not giving it up in a down cycle so that we come out much more stronger when the up cycle comes across.

[Udit Batra, executive]

Amol has given a comprehensive answer. Just 2 points to summarize the whole thing. One, the teams have great muscle now to expand margins during a down cycle, number one. And number two, the pricing that we see is very resilient and I'm excited about -- excited about the prospects as we come out of this down cycle given the product portfolio that we have. I mean, it's been totally renewed. We have leading products across the board that customers have had a chance to test during the down cycle. So very excited about what we're about to see.

The next question will come from Rachel Vatnsdal of JPMorgan.

[Rachel Vatnsdal Olson, analyst]

I wanted to follow up on Dan Brennan's question around China here. It sounds like LC was a little bit better than expected in the quarter, but can you unpack the performance by end market within China there? And then also on the China stimulus dynamic, we've heard from a few of your peers that they've called out an air pocket related to China stimulus as customers are really holding off and submitting orders. So can you clarify for us, have you seen any pause in orders from customers in the region? And if not, why have you guys kind of been more immune to that scenario?

[Udit Batra, executive]

Thank you, Rachel. Look, I mean, China, overall, as I said earlier, declined less than what we had thought it for this quarter. So it went from 26% decline in Q1 to about 10% in Q2. Across the different end markets, there was improvement across the board. Pharma went from about 26% decline in Q1 to 10% decline. Same thing with Industrial, which was a 20-ish percent decline, again 11% decline in Q2. And Academic and Government, which had -- which still has very high comps went from over 40% decline to slightly less than 30% decline. I mean, the most interesting thing here is that the replacement cycle is starting to show life in China already.

We went from over a 40% decline in Q1 in LC, over 40% to now less than 10%, which was better than the rest of the world, right? So we're starting to see customer activity pick up in China. It's still negative growth versus previous years, but it's starting to get better quarter-on-quarter. And on your question on the stimulus, look, I mean, we are having a ton of conversations with our customers as the activity level remains consistent, right? So the activity level has remained consistent. It's actually improving quarter-on-quarter.

From a stimulus perspective, as I said earlier, it's a broader stimulus, it's over a longer period of time, and it specifically targets instrument replacement. So we've been spending a lot of time with our customers, identifying the age of their instruments, defining eligibility versus what the government has targeted and helping them do the paperwork to submit proposals for funding that becomes available.

We don't expect that to impact revenue this year. But surely, it will impact what we see in 2025. So overall, improving conditions across all end markets, especially in Pharma, especially in LC, no real sign of what you're calling an air pocket. Activity is continuing at a baseline level, getting better and customers are getting prepared to get funding from the stimulus.

[Rachel Vatnsdal Olson, analyst]

Great. And then I did want to follow up on 2025 quickly. So can you walk us through your exit rates at 4Q? You've kind of talked about some of this replacement cycle starting to heat up in the back half. If we learn some of the weaker comps on the China dynamics that you talked about as well, how are you really thinking about that exit rate underpinning 2025? It looks like the Street is currently just shy of a 6% organic growth rate. So just at an early starting point, how comfortable are you with that?

[Amol Chaubal, executive]

Yes. Look, I mean, if we sort of extrapolate our guide and say, where will Q4 and our '24 exit rates will be a good -- even for ex-China for LC and MS will be a good couple of hundred basis points below the historic average. And this is ex-China, right? So that gives us a lot of hope and comfort that we are at the bottom of this whole slowdown in the replacement cycle and the fleet out there has aged meaningfully beyond its life needing replacement particularly for LC. And then China is a twofold equation of when the fleet is aged far more than that. But then the question is, when does these generic companies feel comfortable with their status and when do they start replacing.

And we're seeing signs of that, right? We've had a few generic companies in China already starting to replace their fleet and we think others will follow over the course of next few quarters.

[Udit Batra, executive]

I just want to embellish a little bit on what we're seeing at the end of Q2 that starts to give us confidence, right? June is one of the largest months of the year for us. And it has surpassed our expectations, right, both in sales and in orders. So there's a lot of momentum that we've built going into Q3. So that gives us confidence in its a lot in the areas that we've just discussed, right? So it's consistent with an improving trend in the industry.

Second, as I said, I spent a fair amount of time with customers, both in Europe and the U.S. in this last quarter especially in large Pharma. Customers are now used to the additional steps in the procurement process.

In fact, one of the largest pharma companies had introduced several steps in the process, which their internal teams were also learning and we were also learning about and that sort of -- that gave a little bit of pause to how fast the orders were converting to sales. This time around, when we said in March, order quality is high, like clockwork, we've seen them convert into sales towards the end of June.

So now the funnel predictability is way better than we've seen, especially in large Pharma and the funnel -- the order quality and the funnel strength is pretty good as we sit looking into the back half of the year.

[Operator]

The next question will come from Dan Arias of Stifel.

[Daniel Arias, analyst]

Can you maybe just refresh us on the picking around the upgrades within this replacement cycle that we're talking about taking place here? And what I mean by this is, obviously, things are still shaky out there on the CapEx side. So when these LC customers come back into the market, should we assume that there's maybe less HPLC to UPLC transitioning and what you see during historical periods? Or do you think these upsell dynamics and the conversion to UPLC could be fairly typical?

[Udit Batra, executive]

I think it's a great question, Dan, right? And I would look at it 2 ways. One, the HPLC to HPLC conversion, right? And that's a robust trend and we have line of sight on what the fleet is. And there, we offer our customers 2 options, go to the Arc HPLC, which is done really, really well, even during the downturn. And then the Alliance iS, which is now also available for biologics with our premier technology, right? And that has been received extremely well.

In a way, the slowdown in the market allowed many of our customers to sample the benefits of Alliance iS, which reduces errors in the QC environment by 40%, which is a significant advance probably the most important advance in the last decade in the HPLC segment itself.

So we feel very good on the like-for-like replacement already. Second, when you think of HPLC to UPLC transitions, we are seeing that as well and GLP-1s are case in point where we see that transition happening. And now on that, let me make 2 comments. One, you've seen that our Biologics revenue as a fraction of overall Pharma has gone from roughly 20% to over 35% in the last 3 to 4 years, right? So that has been a very deliberate effort, not just on the UPLC side, HPLC to UPLC side but also in introducing what we call the premier technology, which is tailor-made for large molecules.

That is now also available on the UPLC segment, which allows customers to transition the larger part of the pipeline, which is Biologics from HPLC to UPLC very comfortably where now the experimental time is reduced dramatically with the premier technology. So we're seeing both and we are well prepared if the customer decides to remain with HPLC. And equally, we are seeing the trend continue as more and more large molecules and novel modalities come through the pipeline from people transitioning to HPLC to UPLC but there, again, on the receiving end, our UPLCs now have the premier technology, which basically reduce experimental time dramatically. I hope that gives you color into the transition.

[Amol Chaubal, executive]

And just to add to that, right, I mean, if you look at our historical instrument growth pattern, the 5% instrument growth has roughly about 50 to 70 basis points of price and 3% of volume, the remaining 1.5% or so really comes from upsell, right? And when we quote our price numbers, their like-for-like SKU and like-for-like geography. So that doesn't include when a customer chooses say, Arc HPLC or Alliance or Alliance iS or Arc HPLC. And in order to achieve that 1.5%, we only need about 7% of these customers to choose an upgrade given the current innovation and the pricing that is out there. And 7%, we feel super comfortable with huge unmet needs that some of our newer launches are directly addressing, which customers are appreciating.

The next question is from Puneet Souda of Leerink Partners.

[Puneet Souda, analyst]

Udit, for you, if I could ask, the June order growth improvement, the significant momentum you talked about in June, has that continued into July as well? And could you elaborate if this momentum is in mostly in Pharma, North America and Europe, it seems like there's some -- still some caution on China that's improving. But just wanted to get some more details there.

[Udit Batra, executive]

Great question. And as you know, and I think we've been through this before, we won't comment on July trends but you can assume that June was very robust. Customer activity has been very, very good. And that gives us confidence on what we're seeing in -- what we've guided for in Q3. So June has a lot to do with the confidence that we built in the replacement cycle, the confidence that we've built in Q3, the confidence we've also built in the ramp towards -- ramp in Q4.

[Puneet Souda, analyst]

Got it. And then an Asia question for you. Just thinking about China, first of all, and then I want to cover just Japan and India. China, just wanted to understand in terms of retaliatory risks for tariffs. If you could elaborate where is your manufacturing position? How much of the business is China for China in case if there are tariffs and sort of retaliatory tariffs in 2025? And then on Japan, I believe you grew -- sorry, in Japan, you were down 11%. In India, you grew about 11% in the quarter. Could you talk a little bit about what happened in those geographies?

[Udit Batra, executive]

Sure. So three questions, right? First, on China. I think we used -- in an interesting way we used the downturn to improve our manufacturing footprint in China and that is going to help us as the stimulus come through. We also increased our commercial presence across China. So we feel very good about what the future holds for China, both in terms of local manufacturing, where bulk of our instrument portfolio now is either finished or manufactured in China and on the commercial side, equally good.

Now on your question on India, India has been a star performer for us for many, many quarters. This quarter was no different. We grew in excess of 20% largely on the back of Pharma. And there in Pharma, LC grew close to 50%, right? And you heard that right, close to 50%. And so that India goes from strength to strength. And the Indian government is giving stimulus to like many other countries to their Academic and Government segments. And there, too, we're benefiting a lot. That segment grew quite rapidly where the funding is captured. And then on Japan, it was a 1% constant currency growth.

[Amol Chaubal, executive]

Yes. I mean, look, Japan, Puneet likely you are looking at the reported number, right? And you know where Japanese yen has been over the last year, that's like close to 11% headwind. So at constant currency, we're more or less flat and that's also sort of the reason why the currency impact for us is somewhat higher and we had to increase it to 1.5% driven by Japan because we have a reasonable Japan footprint. And our team is doing relatively well coming out of the March year-end. So what you see progressing in Q2 and onwards we see healthy demand, and we see good funnel activity in Japan.

[Udit Batra, executive]

Yes. And then just coming back to India. Very excited about the prospects there. As with China, during a downturn, we've sort of figured out where to increase our commercial presence in India, we go from strength to strength. The commercial presence has been increased across the Board. We've increased our collaborations on the ground. And India has gone in the last 2 to 3 years from less than 6% of our sales to close to 8% of our sales, right? So it's becoming a more significant part of our business and it's growing really, really well.

[Operator]

The next question will come from Jack Meehan of Nephron Research.

[Jack Meehan, analyst]

So I wanted to ask about kind of this dynamic of instruments starting to recover, but more looking at it from a margin perspective, Amol was curious, like just how a changing mix dynamic in the second half of the year and into 2025, what that actually -- what that means for gross margin progression?

[Amol Chaubal, executive]

Yes. Great question, Jack, as always. Look, I mean, there is going to be some negative mix impact from more instruments when instruments start to come back. But as you look at our guide, that's sort of factored in the gross margin, 20 basis points of expansion that we've outlined for the year. And as we go into next year, if the mix sort of returns back to, call it, say, 2019 levels, there will be 10-ish basis points adverse impact, but that's largely covered with the productivity initiatives we have in place. So the marginal got to 20 to 30 basis points still remains intact.

[Jack Meehan, analyst]

Got it. Okay. And then two just housekeeping ones. The first is any updated thoughts on buyback returning to that? And second, can you just remind us any selling day changes throughout the year in the third and the fourth quarter?

[Amol Chaubal, executive]

Yes. So on the first one, right, I mean we continue to pay down debt from the Wyatt acquisition. We are at 1.7% now. So we are at a point where we are actively considering the switch between paying down debt versus buying back shares. I mean, the intention is to gain strategic flexibility as much as possible. So we continue to review options. And on the number of days, I mean, the key thing to note is on Q4 this year, we have 3 more days than Q3 of this year and that partly helps about 1.5% in the ramp from Q3 to Q4. And then other than that, I mean, there are 2 more days in Q4 of this year versus Q4 of last year. Q3 is roughly the same.

[Operator]

The next question will come from Catherine Schulte of Baird.

[Catherine Ramsey, analyst]

First, just maybe on Wyatt, it's great to see that coming in ahead of expectations. Are you seeing any different trends in terms of market improvement in that business, just given the exposure to large molecule in cell and gene therapy? .

[Udit Batra, executive]

Yes. Catherine, thank you for the question. Look, we're very happy with the way the integration has progressed. The synergies are being delivered well ahead of target. That's why you saw growth higher than what we had guided for Wyatt itself. And it's, as you know, focused on large molecule applications, which are growing faster than the small molecule applications, be it RNA therapy, be it mAbs, be it AAVs, viral vectors. We're working closely with customers on increasing applications. What's most exciting is that now the teams are working to take multi-angle light scattering that is the wire technology into QA/QC with basically our Empower software, right?

And this is really exciting. Now you can imagine that large molecules don't have so many different analytical techniques that are in QA/QC. It already has liquid chromatography, to some extent, capillary electrophoresis and now multi-angle light scattering, all of these now if they are on and now the QDa II gives us mass analysis. If all of these now, if they talk to Empower allow our customers to submit data to regulators, some very exciting, really good progress on that front, even in a down market, we're seeing good demand for multi angle light scattering.

[Catherine Ramsey, analyst]

Great. And then maybe just going back to the guidance update. Can you just elaborate on if there are any specific areas of that conservatism that you added to your assumptions? Was it around China, Pharma or is it really broader than that? Any further color would be appreciated?

[Amol Chaubal, executive]

No. Look, I mean, most of our guidance caution that we've put in place is around our ex-China business. We just caution for a slower-than-anticipated pace of recovery. China, if anything, if you look at last 2 quarters, we've exceeded our expectations. We haven't just been bold enough to sort of then improve the guidance for the rest of the year, but we remain cautiously optimistic that our team will continue to positively surprise us like they have done in the first 2 quarters.

[Udit Batra, executive]

It's a great setup for exceeding expectations as we go through the year. And it's just the guidance philosophy we talked about at the beginning of the call that Vijay started with, and it's a great place to sort of end the call. I mean it's basically what we've done all along. We look at a lot of data from customers, from funnels. Second, we spend a lot of time looking at history of LC replacement in particular, which bodes well. And third, talk to a lot of customers on how they're receiving our new products, how their spending and growing and all 3-point towards a more positive second half of the year than we've seen. So that's all been factored in Catherine. Thank you for that question. Caspar?

[Caspar Tudor, executive]
