Management announced the acquisition of Renesas' timing business, expected to significantly alter SiTime Corporation's scale and customer access, with anticipated $300 million in accretive annualized revenue and approximately 70% gross margins attributed to the transaction. The core Comms Enterprise Data Center business delivered 160% year-over-year growth in the quarter and remains the company’s primary growth engine, benefiting from increased AI capex and new product adoption in high-value applications. Guidance for the upcoming quarter points to continued CED business expansion, sequential revenue growth, and gross margin accretion amid ongoing product mix improvements.
Rajesh Vashist, Chief Executive Officer, and Beth Howe, Chief Financial Officer. Please note, in addition to the respective press releases issued this afternoon, a supplemental slide deck related to the proposed acquisition is available on the Investor Relations section of the company's website at investors.sitime.com.

Please refer to the company's press release issued earlier today for a detailed reconciliation between GAAP and non-GAAP financial results. With that, it's now my pleasure to turn the call over to SiTime Corporation's CEO, Rajesh Vashist. Please go ahead.
Rajesh Vashist: Thank you, Brett. Good afternoon, everyone. Thank you for joining us today. We have a lot to talk about. We announced exceptional results for 2025, and we also announced a transformational acquisition. I'll begin with our business and our performance, and then I'll turn to the transaction. Q4 2025 was another exceptional quarter for SiTime Corporation. We delivered $113.3 million in Q4, up 66% year over year and earnings per share tripled from $0.48 to $1.53. In Q4, every end customer segment grew year on year, as did every region. Gross margins in the quarter grew significantly up 61.2%. I'm particularly pleased about this achievement.
In the beginning of 2025, we said we would exit the year at greater than 60% gross margins and we achieved it. We predicted this expansion of gross margins because we anticipated mix changes to higher value products, and we reduced new product costs as they moved into volume production. For all of 2025, we delivered $326.7 million, up 61% year over year. Every end customer segment and region showed growth. Earnings per share more than tripled from $0.93 to $3.20. Demand remained very strong exiting the year, which is an indication of significant future growth in 2026.
While we don't usually discuss our book to bill, we wanted to give you a metric of the demand strength across a customer base as we go into a strong year. So our book to bill was over 1.5 at the end of Q4, and we have excellent visibility for the year. Channel health remains solid exiting 2025. Distributor and contract manufacturer inventory levels were in line with our target reflecting strong sell-through and disciplined supply management. Design win momentum remains solid across all end customer segments and regions, another indication of growth in 2026 and beyond. Q4 growth was again led by Comms Enterprise Data Center, CED, business, which grew 160% year over year.
This marks the seventh consecutive quarter of over 100% year over year growth. Additionally, our 2026 CED forecast has grown since our last earnings call driven by increases in AI CapEx spending. The two to four times increase in computing power of the new XPUs, GPUs, CPUs, is driving the need for faster networking infrastructure and accelerating the adoption of 1.6 terabit optical modules. Our customers have recently increased the 2026 forecast for our oscillators used in 1.6 terabit optical modules by 50%, which is over and above the increase that we reported in November. This move to 1.6 terabit drives the need for higher clocking frequencies from our oscillators for which we get higher ASPs or average selling prices.
The increase in 1.6 terabit modules notwithstanding, demand for oscillators used in 800 gigabit optical modules continues to remain strong. In parallel to the increase in bandwidth of networking infrastructure, the hyperscalers are deploying more XPUs for training, as well as getting ready for inference.
Beth Howe: Since November, this trend has driven a 50% increase in 2026 forecast of our Super TCXOs which are used in both computing infrastructure and the supporting smart NICS or network interface cards. SiTime Corporation's goal has always been to deliver predictable revenue growth. At IPO, CED was just 12% of our revenue, and then we created a strategic plan to expand it to 40 to 50%. Since then, our focused investments in product development, as well as customer acquisition have paid off handsomely. CED today makes up 53% of our revenue, and that is exactly where we want to be.
I'm also very pleased that a large portion of this revenue comes from high value products reflecting the sustained benefit that we bring to our customers. Our CED strategy laid the foundation of our success today and we're using this as a blueprint for rapid growth in our other businesses. We continue to grow across all other end segments, aerospace defense, automotive, and industrial, are all benefiting from increased adoption of autonomous systems and physical AI where systems perceive, reason, and interact in the physical world in real time. These systems need accurate positioning sensor fusion, motor control, and precise synchronization. Where precision timing is essential. Example, in humanoid robots, we see up to $20 of a precision timing product.
And robotaxis in level four ADAS or self-driving cars require up to $15 of precision timing content. In defense, where worldwide spending is accelerating, our product resilience is driving adoption in a variety of applications. In the next few years, we expect that each of our automotive, defense, and industrial businesses to exceed $100 million annually. Entering 2026, demand drivers remain firmly in place. Our strategy remains unchanged, to lead in high value precision timing applications deliver differentiated system level solutions, and scale our operating model to drive long-term value creation. The combination of deep engagement in AI infrastructure, and broad participation across diverse segments positions us exceptionally well for continued growth.
I'm confident in our trajectory and excited about the opportunities ahead. With that, I'll now turn the call over to Beth Howe, our CFO, to review the financial details, after which we'll be happy to take your questions.
Beth Howe: Thanks, Rajesh. Today, I'll walk through our fourth quarter and full year 2025 results and then I'll provide our outlook for 2026. As a reminder, my remarks focus on non-GAAP financial results which are reconciled to GAAP in our press release. Fiscal 2025 has been a pivotal year for the company. In which we delivered exceptional revenue growth, expanded gross margins, and demonstrated meaningful operating leverage. Our results reflect the scalability of our operating model, the strength of demand across our target customer segments and the growing strategic value of our products and solutions. For the full year, revenue reached $326.7 million, an increase of 61% from the prior year.
Gross margins for the year were 59.3% and operating expenses were $135 million. Non-GAAP operating profit was $58.6 million, an increase of $58 million year on year or 18% of revenue. For fiscal 2025, our non-GAAP earnings per share more than tripled to $3.20. Cash flow from operations was $87.2 million for the year. A strong improvement compared to $23.2 million in 2024. Reflecting the combined benefit of higher revenue, richer mix, and disciplined expense management. Overall, our momentum reflects a company operating with focused efficiency and increasing strategic impact. Turning to our fourth quarter results. Q4 was a milestone quarter for the company.
As we surpassed $100 million in quarterly revenue for the first time, and generated operating margins of 30%. Revenue in Q4 was $113.3 million, up 66% year over year and 36% sequentially. Revenue was significantly higher than expected as customer demand continued to strengthen in the quarter. Communications, enterprise and data center continued to be the primary growth engine contributing $64.6 million or 57% of total revenue. And rising 160% year over year. Growth in this segment was broad-based and driven by multiple customers across AI and data centers. Automotive, industrial, and aerospace delivered $24.5 million or 22% of revenue, increasing 19% year over year.
And consumer, IoT and mobile revenue was $24.2 million or 21% of total revenue, up 7% year on year. With our largest consumer customer contributing $17 million for the quarter. Gross margins in Q4 were 61.2% representing a 240 basis point improvement year over year and ending the year above 60% as we had at the 2025. The increase was primarily driven by continued mix shift toward higher margin products. Improving manufacturing overhead absorption also contributed meaningfully to the margin expansion. Operating expenses for the quarter were $35.5 million consisting of $19 million in R&D, and $16.5 million in SG&A.
This was in line with expectations and driven by higher headcount variable compensation tied to revenue performance, and continued investments to support our long-term road map. Operating income for the quarter was $34 million, an increase of $26 million year over year. Demonstrating strong leverage and discipline in our cost structure as revenue scales. Interest and other income and expense was $7.4 million. Non-GAAP net income was $41.3 million or $1.53 per share, more than triple the $0.48 reported a year ago. Now let me turn to the balance sheet. Accounts receivables ended the quarter at $45 million with days sales outstanding at thirty-six days. Up from twenty-four days in Q3 as linearity returned to more normal.
Inventory declined to $81.7 million from $86.7 million in Q3 driven by customer shipments during the quarter and continued focus on inventory management. During the quarter, we generated $25.4 million in cash from operations. We also invested $12.6 million in capital expenditures. Finally, we paid $42.2 million to Aura including the final payment for dye deliveries. Ended the quarter with a strong liquidity position of $88 million in cash and short-term investments. Now let me move to our outlook for March. Because of the acquisition of Renesas' timing business is not expected to close in Q1, it has no impact on our guidance.
Looking ahead to Q1, we expect first quarter seasonality to be less than our historical average and that our Comms Enterprise Data Center, or CED, business will grow sequentially. Since consumer is typically down seasonally sequentially in the first quarter, the higher mix of CED and the lower mix of consumer is also expected to contribute to stronger gross margins in Q1. Thus, we project revenue in the range of $101 to $104 million, up roughly 70% year over year at the midpoint.
Gross margin to be approximately 62% plus minus half a point given our expected product mix for Q1, operating expenses in the range of $39 million to $40 million, interest income of approximately $7 million and a share count of 27 million to 27.5 million shares. As a result, we expect Q1 non-GAAP earnings per share to be in the range of $1.10 to $1.17. With that, I'll hand the call back to Rajesh Vashist to discuss our intent to acquire Renesas' timing business. Rajesh?
Rajesh Vashist: Thanks, Beth. To reflect a little bit, over the past two decades, SiTime Corporation created the precision timing category and fundamentally transformed the timing market by delivering highly differentiated products that solve customers' tough timing problems. Along the journey, there were a handful of defining inflection points. Acquiring Renesas' timing business is perhaps the largest, and one of the most exciting. This business similar to SiTime Corporation, has a differentiated broad product portfolio except that's in clocks. Where we have a small footprint. Additionally, they have an enviable financial profile, a respected team, and a thirty-year heritage that started as ICS, then IDT, and finally, Renesas. We are really glad to have this business as part of SiTime Corporation.
We've always said that customers need complete timing solutions, which include oscillators, resonators, and clocks. Our oscillators and resonators are semiconductors, MEMS based, and we have been investing in this technology for the past twenty years. To grow SiTime Corporation's clock business we invested in our own development. In parallel in 2023, we acquired Aura's clock products which had leadership IP and 50 clock products. Now Renesas' timing business takes us to scale in clocking. They are the preeminent brand with 500 highly differentiated clock products. Because they're focused on clocking in CED, industrial, and automotive, they complement our high-performance oscillator revenue.
This 160 engineers that come over to SiTime Corporation at close gives us an opportunity to build an exciting road map of products that would not have been previously possible. With this acquisition, our revenue mix continues its transformation and increases scale in CED. On a pro forma basis, our 2025 CED revenue will almost double with Renesas' 2025 AI data center comms revenue. To this, we'll add our rapid organic growth in 2026, and combine it with their growth. The breadth and diversity of our customers will grow significantly with this along with faster access to customers that we would have secured only several years in the future.
This acceleration of customers will include 10 hyperscalers, seven AI server leaders, 10 networking and communication vendors, and leading automotive OEMs and tier ones, and leaders in mobile, IoT, and consumer. On Renesas and SiTime Corporation's common customers, there is minimal product overlap. And we have an opportunity to generate new revenue by selling our differentiated oscillators to them. It's an unprecedented opportunity for both SiTime Corporation and our customers to collaborate and build on our twenty and thirty-year heritage to reach an extraordinary level of success in precision timing. This is also an exceptional business with great financials. It's expected to add $300 million in the twelve months after close with approximately 70% in gross margins.
75% of the revenue comes from the fast-growing CED segment which is strategically important to us. It also maintains SiTime Corporation's long-term growth rate of 25 to 30%. This acquisition is a monumental milestone towards fulfilling our vision to transform the timing market, solve our customers' toughest timing challenges, and accelerate our path to $1 billion in revenue. We see remarkable opportunities ahead and we are more excited than ever about the future of SiTime Corporation. I'll turn the call over to Beth to provide more details. Beth?
Beth Howe: Thanks, Rajesh. Building on Rajesh's overview of the strategic rationale, I'll walk through how this acquisition strengthens our financial profile and accelerates our long-term growth trajectory. What is most compelling is the alignment between the strategic value of this business and its financial contribution, both of which meaningfully enhance SiTime Corporation's scale, profitability, and cash generation capacity. Financially, this acquisition significantly elevates SiTime Corporation's revenue profile, margin structure and cash flow potential. Approximately 75% of the acquired revenue comes from our comms enterprise data center sector. A fast-growing and strategically important segment for our long-term success. The remainder is diversified across automotive and industrial, further expanding our reach into durable, attractive applications across timing.
As we integrate the business, we intend to invest in go-to-market capabilities to fully capture these opportunities. Importantly, as Rajesh mentioned, our long-term annual revenue growth target of 25% to 30% remains firmly intact. The acquired portfolio operates with approximately 70% gross margins, reflecting the value and differentiation of the products. This positions SiTime Corporation to reach the upper end of our 60% to 65% long-term gross margin target more quickly while expanding operating margins to above 30% as we scale and benefit from increased operating leverage. The transaction is also expected to be accretive to SiTime Corporation's non-GAAP EPS in the first full year post-close.
And finally, with the combination of our organic growth and the attractive profitability of the acquired business, we expect to generate meaningful cash flow. We have structured this transaction to maintain financial strength and flexibility. Under the terms of the agreement, SiTime Corporation will acquire certain assets related to the Renesas timing business, for $1.5 billion in cash and approximately 4.13 million newly issued SiTime Corporation shares, subject to potential adjustments and a 15% symmetrical collar determined by the ten-day volume adjusted weighted average share price as of the three days prior to the execution of the agreement.
We plan to finance the cash portion using a combination of cash on hand and approximately $900 million of committed debt financing from Wells Fargo. Given the strong free cash flow generation of the combined business, we have a clear path to reducing leverage to under two times within twenty-four months following the closing. The transaction is expected to close by the end of 2026 subject to the satisfaction of customary closing conditions including applicable regulatory approvals. We are thrilled to announce the intent to acquire this highly complementary preeminent clocking business as we enter the next phase of our transformation. The combination strengthens our strategic position, accelerates our financial performance, and enhances our long-term value creation potential.
With that, I'll open the call for questions. Operator?
Operator: To ask a question, please press 11 on your telephone, then wait for your name to be announced. To withdraw your question, please press 11 again. We ask that you limit yourself to one question and one follow-up and then return to the queue for additional questions. Please stand by while we compile the Q&A roster. Our first question comes from the line of Tore Svanberg with Stifel. Your line is open.
Tore Svanberg: Yes. Thank you very much, Rajesh and Beth. Congratulations on the strong results and especially on this highly strategic acquisition. I guess my first question on the core business. So you talked about a book to bill of 1.5. I know you're not gonna give us guidance sort of by segment, but you know, could you give us a sense for, you know, where the most of those bookings are coming from you know, as those bookings obviously are generalized generate revenues for the year. Thank you.
Rajesh Vashist: Well, it's no surprise that most of these bookings will come from CED. Because of the tremendous growth in CED. And I think that our customers are seeing the growth going out through the year, through 2026. And many of them are booking in advance of real demand. I don't mean they're ahead of it. I mean, they're on top of it. And I think but the others are not lagging. We still continue to see our diversified growth in all the other BUs as well. But it just happens to be that just because of its scale, the CED is a bigger portion.
Tore Svanberg: Very good. And as a I had a question on the acquisition and how this is gonna play out. So again, it sounds 75% of the revenue is aligned with your CED mix which is great. I guess that means that, you know, there's you know, end markets or applications that Renesas is targeting that did not come with the acquisition. But you also mentioned that, you know, you might be able to in some of those with your resonated products. So just hoping if you could elaborate a little bit on that, especially on the timing of that potential additional growth engine? Thank you.
Rajesh Vashist: So just to be clear, we're getting 100% of the timing business. Whatever is in the timing business, that's called TPD, timing products division, is coming over to SiTime Corporation. There isn't any business which is being left behind. The integration possibility that we are exploring through the MOU is a completely different one than timing. As you may know, Renesas is a prominent player in the MCU business, in the microcontroller business. And there's an opportunity for SiTime Corporation's resonators, the Titan family of product, to be integrated in their microcontrollers. And that's the one we're exploring.
There's a several billion dollar revenue that they get from their MCUs and we are exploring that and being a timing partner to Renesas. Another way of thinking about this, Tore, is that given the fact that the CEO is joining SiTime Corporation's board at the closing, this becomes really quite a partnership. This makes sure that not only are we a supplier to them, but we are also a partner to them as we go through the integration process and the TSAs and so on. So that's what gives me a lot of confidence in the success and the integration of this business.
Tore Svanberg: Makes a lot of sense. Thank you, and congrats again.
Rajesh Vashist: Thank you.
Operator: Please stand by for our next question. Our next question comes from the line of Quinn Bolton with Needham and Company.
Quinn Bolton: Hi, Rajesh and Beth. Offer my congratulations both on the strong results as well as the acquisition. I guess, like, wanted to start with a question on the core business. You talked about demand strengthening through the fourth quarter, the book to bill of 1.5. You guys have been growing the comms business at, you know, over 100% for seven consecutive quarters. And so I guess, Rajesh, I know you're not guiding to 2026, but certainly feels like the growth engines are there to drive better than your long-term average 25 to 30% growth rate in the core business in 2026.
And so just wondering as you think about, you know, what the core business can do in 2026, is there any framework you might be able to provide you know, for sort of that overall growth rate in 2026.
Rajesh Vashist: Well, qualitatively, and I'll have Beth jump in to give you the level of specificity that she wants to give you. Qualitatively, that's absolutely true. We've been growing. We grew in 2024 at 40%. We grew in 2025 at north of 60%. The business continues. You see Google spending. You see Meta spending. There is no stopping in the AI data center world. And then there is the inference part of it or the LLMs come to physical reality, whether it's humanoid robots, or other kinds of ideas around that. So I expect that this is a series of growth years coming from the AI business even beyond data centers. But I'll let Beth add what she thinks.
Beth Howe: Sure. Thanks, Rajesh. No. I think you know, we do expect it to continue to be led by our comms enterprise data center as Rajesh talked about. As he also alluded, I think we do see opportunities across automotive, industrial, and aerospace. And some specific opportunities, especially within aerospace off a small base. But given the increase in drones and other kinds of defense applications. We see a lot of opportunity there. And then finally, in the consumer space, we do expect to see continued growth there as some of our design wins ramp in 2026. And so those are all some of the opportunities and tailwinds we see for the year. And so we're really excited about 2026.
And where we can go from here. And in terms of the opportunities.
Quinn Bolton: Excellent. The question I had on acquisition. Obviously, Renesas is one of the preeminent players in the clocking business. I'm wondering on a lot of the boards or sockets where Renesas plays, are they typically, you know, paired up with quartz oscillators representing an opportunity for you to cross sell or do you feel like the SiTime Corporation MEMS oscillators are already pretty well placed on, you know, a lot of the boards where Renesas timing or clock products are currently used. I'm just trying to get a better sense for know, how much cross selling opportunity do you see bringing these two businesses under one roof?
Rajesh Vashist: Yeah. You exactly put your finger on it, Quinn. We have very little we have some reasonably solid overlap on customers. But, typically, on products, there's very little. So to your point, they are designed in clocking where the solution is quartz crystal. And this gives us tremendous opportunity to expose the values of our semiconductor differentiated MEMS based solutions to the customers and see how we can get design wins for the future. So this is the cross selling opportunity one way. But there's also a cross selling opportunity another way because we have design wins in AI, in GPUs, in accelerator cards, in switches, where it's not our clock that's in there, the SiTime Corporation native clocks.
It is either their clock or the clock of somebody of another competitor. So that gives us in the next iteration, it gives us another opportunity to present the customer with a value proposition of an integrated solution. It's, of course, not physically integrated. It is notionally integrated or put together as making it easy for the customer to use it, as well as to get the performance they need and, of course, the source of supply which is critical in all of these situations where they need to have one source of supply so some things are not out of whack in that. So yeah, clearly, that is the case.
Quinn Bolton: Thank you, Rajesh. And one last quick one for Beth. On the regulatory front, would you expect to require China SAMR approval to close or do you think, you do not need China SAMR to close the transaction?
Beth Howe: Thanks for the question. So we are going through the required regulatory processes in the countries that have jurisdiction. At this point in time, we do not expect to need SAMR as part of those regulatory approvals.
Quinn Bolton: Perfect. Thank you very much.
Beth Howe: Thank you. Thank you. Please stand by for our next question. Our next question comes from the line of Jim Schneider with Goldman Sachs. Your line is open.
Jim Schneider: First of all, on the synergies with Renesas, can you maybe talk a little bit more about within the data center the specific synergies between your products on the oscillator side and what Renesas is doing perhaps on the memory side or otherwise? And beyond the cross sell, you expect there could be some consolidation of overall board timing content away from other suppliers toward a more holistic solution. In other words, is there a way that you could provide a more holistic solution between the two of you that would maybe would, would be disadvantageous using another supplier.
Rajesh Vashist: Right. To be very clear, there is no product other than timing that we are going to be bringing into this. So you mentioned memory somewhat. You know, onto the side. We have no influence on that. We have no connection with that. Only working on one thing and one thing only, which is a timing product division, which used to belong to IDT before that to ICS. So it's a timing business that we are acquiring and our influence is in timing. But the point that you made, Jim, is a very good one, which is that today, we have products that are oscillators and resonators on one side, and clocks on the other.
With their 160 engineers, with our almost double that number of engineers, I think we would be able to address you know, the issues of density, power, resilience, higher throughput, by delivering solutions, by delivering products that are somehow integrated not just physically integrated, but somehow integrated to deliver vastly superior solutions because the need for performance, for jitter, for high speed, for throughput, for lower latencies, for lower power, those remain undiminished not just in AI and data centers where they're extreme, but in all other areas including consumer, including military, aerospace, defense.
In terms of the one part of AI where clock is not being used right now, and we'll have to see whether the place for it is in the whole optical networking in the cabling, in the smart cables, in the retimers. Typically, those are not using clocks. Those are oscillators. But either way, there's enormous opportunity because, as you know, the market is $11 billion for all timing. And SiTime Corporation's only a very small portion of it. And Renesas, large as it is, the timing business, it's still also a very small portion of it.
There's a significant amount of competitors out there, and it gives us an ability to influence at the highest level the highest differentiated, most performance-centric customers. Allows us to influence that.
Jim Schneider: That's helpful. Thank you. And then relative to the model for 2026, maybe give us a little bit of help on two vectors. One, on the 1.5 times book to bill, can you give us a sense about the duration of that backlog? Is that six, twelve, eighteen months or longer? And then separately, talk about what the relative expected growth rate will be in the mobile and consumer business, do you think you can sort of match the growth rate you put up in 2025? Thank you.
Beth Howe: Maybe I'll start with that one, Jim. So in terms of the book to bill, I think Rajesh talked about the fact that we are seeing customers maybe book out a little longer, but it typically, that's well within twelve months. You know, we see a lot of ordering in over the next couple of quarters, but we are seeing some customers book meaningfully in the second half in terms of that already as well. But I would say, definitely weighted to Q1 and Q2. As far as our consumer business, you know, again, there's a lot of activity there, and we've got a design win that we do expect to ramp meaningfully as we go through the year.
And so I think that will drive a lot of performance of that sector.
Jim Schneider: Thank you.
Operator: Thank you. Please stand by for our next question. Our next question comes from the line of Thomas James O'Malley with Barclays. Your line is open.
Thomas James O'Malley: Looking at your long-term gross margin model, 60 to 65, you're saying the acquisition adds potential to the high end of that. If I look at your business stand alone, over the last year, you've had two quarters where your incremental growth margins are dropping through at 68-70%. You obviously have a mix factor that's helping the gross margins in the March, but as we look at 2026, should we be thinking about something a little bit ahead of that original target just because of the mix of business moving more towards AI? Anything you can help us with on the margin side as we look through '26.
Beth Howe: So as we think about our I'll start with the gross margin. So mix will be the biggest driver of gross margins in the year. And so I think there's a couple of factors that are contributing to that. The CED growth and mix clearly is a very favorable component of that mix. And then the other is the consumer business. So in quarters where the consumer business is a lower percentage of the total, that is a tailwind to gross margins. In quarters where you see a stronger mix of consumer, that can be a bit of an offset to those strong CED gross margins.
So that'll as we go through the year, I do expect you know, that mix between those two to be the biggest driver of the gross margin in the quarter. And then as I think about operating margin, I do expect to continue to see favorable operating leverage in the model. So I do expect to continue to grow revenue faster than operating expenses. We do want to continue to invest in the business in a disciplined way to really be able to capture all the growth that we've been talking about.
And so we do want to make investments both in our go-to-market as well as R&D to continue to have these world-class platforms in order to be able to deliver value to customers. But, there is still meaningful operating leverage in the business.
Thomas James O'Malley: Helpful. And then on the acquisition, I just wanted to understand the OpEx side. Could you maybe give us the split of OpEx between R&D and SG&A of the acquired asset? And then when you look at areas where you can see synergies, could you maybe give us some feel for COGS or OpEx where you could see some of the cost coming out. Thank you.
Beth Howe: Mhmm. So in terms of the transaction that we announced today, we are acquiring the assets from Renesas of their timing division, as Rajesh talked about. So this is a carve-out, and we are acquiring just those specific assets, and we will be once we close the acquisition, we will be integrating that into our own business and our manufacturing operations and taking those over. They have a similar kind of OSAP model as we do. And so that will be really the focus for us. We'll talk more about the specifics of the model and the cost structure. We get to close.
Thomas James O'Malley: Thank you.
Operator: Please stand by for our next question. Next question comes from the line of Christopher Caso with Research. Your line is open.
Christopher Caso: Yes. Thank you. First question is on the business as you go into 2026. With regard to content. And can you speak to the content gains that you realize on the 1.6 terabit platforms and then what do you think will be the growth rate of those 1.6 terabit platforms? You know, how meaningful is that, as a part of your business as you go through '26, given those content gains?
Rajesh Vashist: Yeah. Chris, the content gains on the 1.6, I think, is going to be pretty good. It may not be you know, we mentioned it's in the tens of percent up in ASP. And there is an increased number of units being deployed on that far more than we had thought on our last call in November. So we have we're very optimistic about that business. But at the same time, our business in other, in other optical modules like 800, we called out, continues as well as in some of the lower ones. So I think this is a very healthy business.
We are designed in to a large number of suppliers in the optical module, but also in the AEC, the active cables. As well as in the retimer business. So the whole networking part of this business of SiTime Corporation is very strong.
Christopher Caso: Thank you. As a follow-up, just a question on the transaction. And you speak about the combined business staying on your 25 to 30% growth targets for the existing business. Obviously, you've been growing at a faster rate than that now. So as you go forward, within that 25 to 30% are you expecting is basically each business growing at that 25 to 30% going forward? And maybe you could talk about the growth rate of that business that had been within Renesas in the past. You know, had that been you know, steadily growing at that 25 to 30% rate?
Rajesh Vashist: Yeah. We've always maintained that resonators I mean, sorry, oscillators are a system business. It has a resonator, and it has a clock. So it's a system business. And in this in resonators, excuse me again. Oscillators are being used in some places where clocks are not. So for example, in military aerospace defense, oscillators tend to be used over that. Earlier, I just mentioned certain use cases. In networking, in AI, the optical modules and such. Where there isn't there isn't a use case yet for clocks. But in general, I think, therefore, clocking is a slower growth business than oscillators are.
So I think we will get a very good growth rate for the combined business because, as you mentioned, we are indeed in our oscillator-based business, which is most of our business today. Is quite a high growth business since 2024. But we think that adding the clocking business even though it grows at a somewhat slower rate, still keeps growing at such a healthy rate that we are 25 to 30%. We're very confident on that. For the combined business, that is.
Christopher Caso: Right. Thank you.
Rajesh Vashist: Thank you.
Operator: Please stand by for our next question. Our next question comes from the line of Suji Desilva with Roth Capital.
Suji Desilva: Hi, Rajesh. Hi, Beth. Congratulations on this transaction. Great news. Thank you. I was curious. Yeah. And I read the MOU with Renesas as part of the transaction and the integration of the resonator into the microcontroller SoC products of Renesas. I'm curious, is that ahead of the rest of the industry or other folks? Are you working with other folks on similar efforts? Just curious, you know, how that is positioned. Competitively?
Rajesh Vashist: Yeah. That combined. So as you know, thank you. As you know, the Titan family of products is a breakthrough family. There isn't any other resonator in any technology at that level of quality, reliability, size, power, and use case. So many customers, many semiconductor customers and many system customers are looking at designing it in. And as we have mentioned in the past, it's a somewhat slower design win particularly when it goes in into somebody else's chips. Right? So I think it takes a little bit longer to get the design win. Certainly, there's nothing exclusive about this. But and we're talking to them but I think that they are ahead of making this commitment.
And I think this is as you see in the remarks by their CEO, Shibata, that they are using this as a way to pivot this the sale to SiTime Corporation of the timing business and the MOU as a way to pivot deeper into their what they are calling their core business in embedded compute. So I think it's a win-win for both of us. And certainly, as a potential customer of SiTime Corporation, that becomes a bit of a flagship design win. If and when it happens.
Suji Desilva: Helpful color, Rajesh. And then in CED, you've talked about it a lot. Know, the usual suspects growing here, pluggables, AACs, retimers. I'm wondering if there's other applications which are emerging in growth above and beyond those. That you'd call out with the strong growth there or whether it remains those kind of the ones we kind of already know roughly.
Rajesh Vashist: Yeah. So once we know, there are no new categories, but they're new design ins, and the density you know, we always maintained our growth story comes from three legs. One is whatever design wins we have, the end product sells more units. Right? So that's one. The second is there's an upgrade in functionality from win to win. And there's an upgrade in density of chips used in a particular functionality. So what we are experiencing now in some of these with our native plot products is that they were design wins along with oscillators. And there were more of clocks. And then there were more clocks being used in a design win. So I think that trend continues.
And finally, there's a new use case for our products that didn't exist. An example would be an L4 ADAS, or indeed even the retimers, which didn't meet our level of performance sometime back.
Suji Desilva: Okay. Great. Thanks, Rajesh.
Rajesh Vashist: Yep.
Operator: Thank you. Please stand by for our next question. Our next question comes from the line of Gary Mobley with Loop Capital.
Gary Mobley: Everybody, let me extend my congratulations as well. I want to ask about the strong growth that you're seeing in the ability to support that growth from a supply chain perspective. Are there any capacity constraints that you see now or on the horizon that are causing your ordered lead times to extend? And I guess, conversely, you know, do you see a situation where some of your crystal-based competitors are struggling to fill, you know, surging demand with seems to be industry-wide. And are you able to take advantage of that with your quick turns you know, I guess, supply chain?
Rajesh Vashist: We know of no data that shows that crystal suppliers are struggling. It may be, but we don't know that. But what I can say is that just on the merits of the SiTime Corporation programmability, SiTime Corporation supply chain, the integrity of that given semiconductors, and specifically the quality and reliability of our products, SiTime Corporation is the preferred solution even when there isn't a performance requirement. In fact, we get to charge a premium on our products even when there's no performance simply based on our quality, reliability, support, programmability. We think that we don't have to rely upon anybody's struggle or weakness.
We think we rely on our strength, our value proposition, is strong, and sustainable and customers are recognizing that with every passing quarter, if you will. And we keep on adding to our customer base. Both in existing customers and existing applications, but also new applications. So we feel generally very confident in our supply chain. We had some challenges in the beginning of last year. When we were trying to launch new products at the same time when demand was surging. But we more than caught up in Q3, Q4 and we look forward with a lot of confidence to this year. In terms of supply chain.
Beth Howe: And I think the other thing, we continue to work very closely with our supply chain partners as we see kind of the industry evolving and are mindful of our costs and working very closely with them. To ensure that we can continue to secure the supply that we need and the lines that we need. And, again, watch the cost as well as we see the tightening that I think everybody is seeing.
Gary Mobley: Thanks. As follow-up, I wanted to ask about a few details on the acquisition or the asset carve-out. Just to confirm, this is a fabless business model. And related, is there any foundry crossover? And I just want to confirm that, you know, most of the engineering team, I presume, was down the street from SiTime Corporation's headquarters. Correct?
Rajesh Vashist: Well, starting with the engineering team, it is located mostly in North America. There is a large group in Ottawa, which is the IDT group. Ottawa seems to have a long time ago, ZARLINK also. So there's a nice pool of people that we could hire from in analog design. The next one, as you rightly point out, is right here in South San Jose. And available. And the third one, which is rather large as well, is in Tempe, Arizona and we're looking forward to that as a new location for us. They also have some people in Shanghai, which is new. And then there's people, across some parts of Asia and smaller numbers.
In terms of the other question, which was around Fabless, actually, it's a really very good match. They are mostly they are all IDT. And therefore, they are TSMC point one eight micron, which is fantastic. Since TSMC is already a great supplier to SiTime Corporation. And, also, they are with GlobalFoundries in the 55 nanometer, which is great. On the back end, there's almost complete great connection with ASC and CARSM. And some of the others in Asia. So we are very confident that we can make this the back end of the supply chain work really well.
Gary Mobley: Thanks again.
Rajesh Vashist: Yep.
Operator: Thank you. Ladies and gentlemen, I'm showing no further questions in the queue. I would now like to turn the call back over to Rajesh Vashist for closing remarks.
Rajesh Vashist: Look. This has been a long time coming. And we've been on this spot. When we raised money, many of you asked us what it's for. And we've always been very clear that our next M&A would be in timing. It would be at scale. It would be equal to or better than our gross margins. It would be equal to or better than our net profit margins, and it would not take down the growth rate of 25% to 30% that SiTime Corporation's long-term growth model. I think we have fulfilled that on every count. And not only have we been able to get a clocking business, there couldn't be. There isn't one.
There isn't a better clocking business, and this in the world. The coming together of all of this by our standards, makes us a big company, but we'd still be a pretty small company in the large timing business. The timing business is $10 billion to $11 billion and it grows at 5% to 6% year on year. At the end of these ten years, we'll probably be $17 billion to $18 billion in size. And SiTime Corporation has a long way to go to get to be a large player. Coincidentally, or by design, we don't intend to be a large player. We're not a market share game. We're a value differentiation high growth game.
And so I really look forward given our spectacular results, and our outlook for 2026, plus this new acquisition whenever it closes, to create a billion-dollar company that is solely dedicated to solving tough timing problems of our customers. Timing, as we know, is the heartbeat of all electronics, and SiTime Corporation is dedicated to it. Thank you.
Operator: Ladies and gentlemen, that concludes today's conference call. Thank you for your participation. You may now disconnect.
Tore Svanberg: Thank you.
