Thank you, Brett. Good afternoon, everyone. Thank you for joining us today. We appreciate the continued support from our long-time investors and warmly welcome new SiTime investors. SiTime is pioneering a new category in semiconductors, precision timing, part of the broader $11 billion timing market. To drive growth, we are focused on high-value applications in AI data centers, automated driving, defense and industrial, and successfully delivered differentiated products with exceptional performance and reliability. This focus continues to pay off as we build a high-growth, diverse business across markets, applications and geographies. Q2 2025 was another exceptional quarter for SiTime. We delivered revenue of $69.5 million, which was a 58% increase year-over-year. Gross margin increased to 58.2%, and as new products contribute to a higher percentage of revenue, we expect to see gross margin expansion with revenue growth. EPS increased to $0.47, up from $0.12 a year ago, and every customer segment grew in Q2 2025. Exiting the quarter, we have robust bookings and a healthy funnel. In today's world of significant AI growth, it's no surprise that our data center customer segment continues to lead our growth significantly. In fact, it grew 137% year-over-year. Here, our Elite family of oscillator products, Elite, Elite RF, Elite X, continue to shine along with our Cascade clocking family. These products' performance drove strong design win momentum across the market, including switches, NIC cards, optical modules and active electrical cables. SiTime continues to be the only company that offers a full suite of precision timing solutions that includes oscillators, clocks and software, giving us architectural advantages. As we expand our offerings with new products, our dollar content in the application will grow. For example, in a cloud service provider's 102 terabit switch design, SiTime's dollar content increased by 125% with the addition of a customized lock. Similarly, in a silicon provider's network switch design, SiTime's dollar content increased by 100% with the addition of multiple clock chips. Already in 2025, in AI, we have added design wins worth several hundred million dollars. For SiTime, winning the AI data center market is important, and we will accelerate product development and customer acquisition to expand further in these markets. In this age of accelerated innovation and fast deployment of AI hardware, SiTime is very well qualified to meet the rapid growth in customers' demands. Our programmable product architecture works very well here, and our team and our suppliers have done a phenomenal job of keeping up with demand. One of SiTime's strengths lies in the diversity of our business. This was again evident in Q2 2025, where all markets and geographies demonstrated continued growth. Our revenue grew double-digit percentages year-over-year in mobile, IoT, consumer and auto, defense, industrial as well as every region. In the automotive, defense and industrial markets, a growth theme is around fully autonomous operations playing directly to SiTime's strengths. Precision timing from SiTime is required for accurate positioning, sensing, motor control and synchronization for fully autonomous operations in L3+ and L4 ADAS vehicles, drones and factory robots. In automotive, robotaxis are gaining significant traction. In warehouses, millions of robots are automating tasks and defense spending is accelerating with NATO, for example, expected to spend at an 8x faster growth rate. We are designed in into the leading robotaxi, robot and defense equipment, and as these markets scale, so will our revenue. SiTime has significant experience with a decade of investments in these markets, and we have learned how to anticipate the needs and generate products and features that will drive revenue from these applications. Lastly, in the mobile IoT consumer market, our newly announced Symphonic mobile clock generator chip provides significant power and accuracy advantages to GNSS and 5G applications. It has already started to contribute to our revenue, and we expect its contribution to grow significantly in 2026 and beyond. As we move into the second half of 2025, we anticipate sequential revenue growth in each of Q3 and Q4, supported by strong demand in AI infrastructure and continued momentum across markets. This is the second consecutive year where we expect to grow revenue by at least 40%. We also see that as more customers experience the benefits of our precision timing, more opportunities come to us. To seize them, we will continue to invest in both R&D and customer acquisition while improving operating leverage. To summarize, our success is being driven by both the depth of our engagement in AI, data centers and the breadth of our reach across diverse markets. This balance gives us resilience and positions us for sustainable growth. I'm confident in our trajectory and excited about what lies ahead. I'll now turn the call over to Beth Howe, our CFO, to discuss our financial results in more detail. Beth?

Thanks, Rajesh, and good afternoon, everyone. Today, I'll walk through our second quarter fiscal 2025 results and then provide our outlook for the third quarter. As a reminder, I'll focus on non-GAAP financials, which are reconciled to GAAP in our press release. In the second quarter, revenue increased 58% year-on-year to $69.5 million, fueled by CED, which grew 137% year-on-year to $36 million. Our other markets grew double digits with sales into automotive, industrial and defense market up 11% year-on-year to $16.5 million, and sales into the mobile IoT and consumer market up 23% year-on-year to $17 million. Sales to our largest end customer totaled $11.8 million. In terms of the mix of revenue, the comms, enterprise, data center market represented 52% of revenue, while the automotive, industrial and defense market as well as the mobile, consumer, IoT market each represented 24% of revenue. Non-GAAP gross margin was 58.2% for the quarter, up 80 basis points sequentially, driven by favorable product mix and improving product costs. Total non-GAAP operating expenses were $33.3 million, in line with expectations. For the quarter, R&D expense was $19.5 million and SG&A expense was $13.8 million. We remain disciplined in our approach to investing to drive future growth. Q2 non-GAAP operating income was $7.2 million, an improvement of $9.9 million or 16 percentage points versus the same quarter a year ago. Q2 non-GAAP net income was $11.6 million or $0.47 per share. Turning to the balance sheet. Accounts receivable were $26.9 million, with DSO improving to 35 days versus 42 days in Q1 due to better revenue linearity. Inventory at the end of the quarter was $84.1 million compared with $82.6 million in Q1 as we ramped production for key new products and continued to maintain strong wafer balances for assurance of supply. During the quarter, we generated $15.3 million in cash from operations and invested $18.3 million in capital expenditures. I expect CapEx to step down from these levels in the second half of 2025. During the quarter, we completed a follow-on public offering of 2 million shares at $200 per share, raising $388 million in net proceeds. These proceeds strengthen our balance sheet and support strategic investments in innovation. Our balance sheet remains strong, and we ended the quarter with $796.7 million in cash and short-term investments and no debt. Now I'd like to provide our outlook for the September quarter. For Q3, we expect revenue of $77 million to $79 million, gross margins of between 58% and 59%, and operating expenses to be in the range of $34 million to $34.5 million. Reflecting the offering we completed in June, we expect interest income of $7.5 million to $8 million, and a diluted share count of approximately 26.8 million shares. As a result, we expect third quarter non-GAAP EPS to be in the range of $0.67 to $0.75 per share. In closing, our results demonstrate strong top line momentum and the meaningful operating leverage in our model as we scale. Our expanding product portfolio is delivering differentiated solutions in large growing markets and customer engagement continues to validate our value proposition. We believe we are well positioned to drive sustained growth, operating leverage and long-term value creation. With that, I will open it up for questions. Operator?

Our first question comes from Chris Caso from Wolfe Research.

For the first question, if you could go through what your expectations are for growth by segment as you get to the guidance.

Sure. So I'll take that one, Chris. As we think about the different markets, again, I would expect that our CED led by AI continues to be our strongest growth area. In addition, as we get to the second half, we typically see stronger seasonality in our consumer markets and so we would expect that as well. And then our auto, aerospace, industrial, we've seen some strong growth in several applications in that area, better traction in aerospace, for example, as well as good traction in industrial. And so we expect growth in all three markets there. But I would focus on CED; it's probably our strongest grower in the back half similar to the front half.

Okay. Great. That's helpful. Just as a follow-up, I guess one question would be anything extraordinary of note in your guidance with regard to the mobile segment for the third quarter? And I guess in the past, within that segment, you've had sort of a policy of not including new design wins in guidance unless the products have actually shipped and you confirm you've been in there. I guess, one is anything extraordinary to say within the guidance? And then secondly, is that still your policy with regard to the mobile segment?

Yes. First, let me address the policy, Chris. The policy is that generally, as you know, consumer products, but particularly, mobile products tend to be very volatile. So we only give guidance when we can see it. When we talk about the 40% growth in my prepared remarks, that comprehends the mobile because we now have enough visibility this year to be able to say that. When it comes to next year, we'll probably do what we did at the beginning of this year, which we'll carve out that portion of the business, simply because we wait till greater visibility, and we get visibility. We start to give you pass through that visibility to you. So hopefully, that helps.

Right. So to summarize, for product launching this year, you would include that in your guidance because now you do have that level of visibility?

Correct.

Our next question comes from Tore Svanberg from Stifel.

Congrats on the strong results. I mean, not to sort of pick on a very good trend, but I was a little bit surprised to see your mobile, IoT, consumer business kind of flat sequentially, and I think your largest customer was just barely up sequentially. So just curious if there's some puts and takes there in the business, especially given your sort of new content and some of the devices there.

Yes. As we evaluate our mobile, IoT, and consumer business, our primary focus remains on the communications, enterprise, and data center market, due to the significant growth opportunities and our investments in new products for that sector. This market often serves as the entry point for expansion into aerospace, industrial, and automotive sectors, which is why it receives the bulk of our investments and attention. While we do identify some potential in mobile, IoT, and consumer segments, we will selectively pursue opportunities as they arise, including a recent success we achieved this year with a particular customer. In terms of consumer seasonality, when a product is launched, the initial quarter involves sell-in as we supply the channel with the new product, typically noticeable in the first quarter after launch. Additionally, consumer demand usually sees stronger performance in the latter half of the year, especially in the third and fourth quarters, compared to the first half. This pattern is reflected in our current results.

And Tore, Rajesh here. I wouldn't look too much into it. It's the consumer business. It's dynamic. We know it. It's up, it's down. So I wouldn't read too much into that.

No, that's fair. And I guess as my follow-up for you, Rajesh. As we go into the second half of the year, I think SiTime has a pretty unique view into all end markets given your diversified revenue base. Obviously, the data points remain very, very strong on data center. But I would say in sort of more traditional analog markets like industrial and auto, the data points are quite mixed, especially because of tariffs. So I'm just curious, what are you seeing in some of your non-data center segments, not just in Q3 but even into Q4?

Yes, there is some softness in the automotive sector, which we have noticed, but we are still experiencing growth. We definitely see strength in the industrial sector and significant strength in aerospace and defense. Although it's not a large area for us, it is expected to grow quickly, and we have high hopes for it. Even in the automotive market, the design wins we are securing point to future growth, especially regarding L3+ and L4 automation and advanced driver assistance systems. While we might not see substantial launches before 2026, we anticipate significant opportunities in 2027 and 2028. For the industrial sector, we focus on industrial robots driven by the demand for autonomy and synchronization. Our strengths in sensing, motor control, and synchronization are applicable across all three sectors: industrial, automotive, and military aerospace defense. This unique positioning excites us, and we plan to make significant investments in these areas.

Sounds good. Congrats again.

Our next question comes from Suji Desilva from ROTH Capital.

You talked about gross margin tailwinds coming in the next quarters from new products increasing in the mix. Maybe you can help us understand where new products are as a percent of revenues now by that designation? Where they were a year ago? And what would be the pace of the increase in the next year or two to help the margins?

Well, I don't know if I can give you regular percentages, but I can give you some indications. And the indications are that I referred to the Elite family of products. Those are definitely all our new products, Elite, Elite X, Elite RF, and the Cascade family. And in fact, our whole clocking family, whether it's the Chorus and so on. Definitely in the area of data centers, even in enterprise and communications, so the whole what we call CED, we expect more of the new products than of the older products. It's certainly true that the new products are significantly higher ASP. They are, as I've mentioned before, anywhere from $3, $4 to $10, $12. And so they're significantly valuable in that regard. The design wins coming out in the military, aerospace, defense as well as in the automotive and industrial are also significantly in the new areas. Consumer tends to lag a little bit. And as you know, we have spent most of our R&D in the first two that I said. But consumer, mobile, IoT, we have a bunch of products. And of course, the Symphonic product, we have a lot of high hopes for in this year, the second half as well as in the coming year. So I think it's going to be pretty evenly spread in these markets, but I expect that 2026 will be significant in the new product space. I think this is definitely a transitional year.

Okay. And then maybe kind of digging into the data center content that you've gained, just maybe one level down. Like when you have the opportunity to win a higher dollar clock in some equipment, but other equipment, maybe it's less content. Can you just help us distinguish what gets you that higher content and whether you have upgrade opportunities in other places where you have content or how that lays out across the data center equipment, the switches, the AECs and so forth?

Yes, what sets SiTime apart is that we offer a complete system. We are unique because we manufacture both oscillators and clocks in-house. This allows us to combine them not just as separate components, but as an integrated system, which is crucial since customers have specific timing needs. Relying on different suppliers—typically a quartz crystal supplier for oscillators and a separate company for clocks—can be problematic, especially in demanding environments that require high performance, low latency, and high throughput. For instance, in the terabit switch design we executed, we added value by incorporating a highly customized clock, as many clocks are tailored to specific applications. We also included multiple clock chips in the networking component. Essentially, we address our customers' needs at the architectural level, and this strategy is consistently applied across our various markets, including higher-end consumer products. For example, our Symphonic product uniquely integrates both clocking and oscillator functionalities. This systems approach is worth considering.

Our next question comes from Quinn Bolton from Needham & Company.

Rajesh and Beth, let me offer my congratulations on the nice results and outlook. I guess I wanted to start, Rajesh, I think in the past, you guys have addressed your content opportunity on some of the GPU rack platforms that have been announced over the past, say, 6 to 12 months. But wondering if you have similar content opportunities on the hyperscaler ASIC-based platforms? Do you tend to see similar opportunity on those ASIC platforms as the merchant GPU platforms? And then I've got a follow-up.

Yes. The short answer is yes regarding the hyperscalers. However, our market penetration varies; we are not equally established with all the key hyperscalers. Some have a bit more penetration than others. In the areas where we are present, we also experience significant penetration, though it tends to lag slightly behind. This is because companies that produce GPUs and CPUs usually progress faster. By collaborating with them, we gain a better understanding of the use cases and market dynamics. These semiconductor companies often focus not just on CPU and GPU accelerators, but also on NIC cards, switches, and pluggables. It's natural for us to engage with them more. Nonetheless, we are continually making inroads into the hyperscalers. I believe the architectural advantages increase as we target a larger market alongside the merchant silicon suppliers, if that makes sense.

Yes, it does. It does. And then a follow-up on the Symphonic product. I guess a couple of questions. I believe that targets more of the mobile, consumer, IoT segment. Wondering if there are particular applications where you're seeing success with Symphonic. And you mentioned it's a clock plus an oscillator. Does that meaningfully increase your ASP in some of those mobile IoT product categories? Or does it come in at similar ASPs to products that you already sell into that end market?

Yes. No, it definitely comes at a higher ASP, simply because, as I said, it's a system-level approach. So we're solving multiple problems. It's not just that we are integrating, oh, here's the cost x and a price x and price y of an oscillator plus a clock; you put them together, you don't get x plus y, you get something more than that because when you do it as a system, you solve many other problems on the board, on the bill of materials that the customer now doesn't have to use, whether it's discrete, whether it is the way the clocks are laid out and so on. When we did Symphonic, we were looking at the 5G market. We were looking at the GPS market. We were looking at the millimeter wave market. And those markets will come, but we don't see them happening today. I think they'll come maybe in a year or so, particularly in the area of IoT, particularly in the area of factory and enterprise-based IoT that will use 5G private networks, and we see that coming. But it's a little bit of a ways, but we are going to be ready for the market and we'll be there well ahead of anybody else.

Our next question comes from Thomas O'Malley from Barclays.

Congrats on the nice results. So if I look at last quarter where you kind of let things off, at the high end of guidance, you kind of talked about 30% kind of plus growth for the full year. You're clearly indicating a stronger growth profile now of greater than 40% versus where you were 90 days ago. You're obviously highlighting CED strength as one of the reasons for the uptick. But more specifically, could you talk about what inside of CED is getting stronger? And like, did you just take some conservatism when you were standing there last quarter? Or have things materially improved in the last kind of 90 days?

Yes, it's a combination of all the segments, Tom. Specifically for the data center, we're focusing on areas like networking, accelerators, and switches. After 90 days, we now have better visibility into the second half of the year. We observe persistent strength, growth, and demand from our customers, which is helping us build a solid backlog and a promising sales funnel. Additionally, we have improved insights into our consumer, mobile, and IoT business, which typically sees higher demand in Q3 and Q4. We're also seeing good growth in those areas. Overall, the rest of the business continues to grow steadily as well. Comparatively, last year, it took us some time to reach at least 40%, but this time we clearly see the path to achieving that.

Helpful. And then just something on kind of the trajectory of the year. So you obviously have the consumer portion, particularly the one customer that's stronger in the second half. And you've said that CED is leading the growth in the second half. Does that mean CED is up the most sequentially in Q3 and in Q4? Or does it mean CED is up the most in aggregate between those two quarters? I'm just trying to understand because it looks like you should see a really big pickup in that consumer bucket into the September quarter. Just maybe help me understand that a little better.

So Tom, this is Beth. As I reflect on the overall year, I anticipate the strongest growth will come from CED. I also mentioned that we expect consumer activity to increase in the second half of the year, and this expectation is based on sequential trends and the typical seasonal patterns associated with the consumer business and that customer.

Our next question comes from Tore Svanberg from Stifel.

I have a few follow-up questions, if that's alright. First, Rajesh, regarding data center architectures, I'm interested to know if there are developments related to rack-level infrastructure. You have a wide range of applications, but I'm curious if there are any timing-related factors at play. It seems you are focused on selling oscillators and clocks, but is there anything else happening that could allow you to engage more significantly?

No, I think these systems are becoming increasingly complicated. Reflecting on the past two to two and a half years, the pace of innovation in this area is remarkable. Having been in this field for a long time, I've never seen such rapid advancements aimed at achieving higher throughput with less heat, smaller sizes, lower latencies, and better performance. It's truly impressive. This demand drives the need for more advanced timing products from SiTime. For instance, when we began in this field, jitter requirements were around 70 femtoseconds. Now, we're aiming for under 20 femtoseconds in just three years. This is just one of many metrics we could discuss, including synchronization, stability, phase noise, and temperature. The rate of innovation from our customers is incredible, and it forces us to innovate faster. Consequently, our products tend to have higher average selling prices and are often part of a broader array of solutions rather than a single product. To address your question directly, there is an increasing demand for system-level solutions and for innovative, higher-priced options in timing.

Yes. That's great color. And then just one last one. I know you have still quite a bit of design wins in the 5G space. I know a lot of the focus here near term is still on data center in CED. But just curious if that communications revenue basis is starting to move a little bit.

Yes, it is. We expect more in the coming year, including deployments outside the United States that are looking promising, particularly in India. We anticipate seeing progress in that area. While there is significant growth in the AI data center space, we are also seeing considerable activity in the enterprise sector, not just in communications and traditional end customers.

I'm showing no further questions at this time. I would now like to turn it back to management for closing remarks.

Well, thank you all for this. All I'd like to say is that these are wonderful times, and we're very happy to be rolling out our products and delivering the solutions to our customers. So thank you for joining us along in this journey.

Thank you for your participation in today's conference. This does conclude the program. You may now disconnect.
