Thank you, Anthony. Good afternoon everyone, thank you for joining our call today. Veeco executed well in Q1 with solid top and bottom-line results. Our team continues to perform well and remains focused on executing our growth strategy to create value for our customers and shareholders. Today, I'll take you through our first quarter highlights and discuss our markets and technologies. John will provide a financial update and guidance, and then we'll be happy to take questions. Revenue in Q1 came in at $154 million. non-GAAP operating income totaled $20 million, and non-GAAP diluted EPS came in at $0.30, all above the top end of our guided range. This quarter's results reflect solid execution. Revenue for our semiconductor products remained elevated, increasing by 20% year-over-year, led by laser annealing.
Our team did an excellent job of managing supply chain during the quarter. While material lead times remained elevated, our suppliers' on-time deliveries have improved. We're starting to see some signs that material lead times could improve in the second half of the year. As we look ahead in 2023, we remain committed to investing in the semiconductor and compound semiconductor markets with differentiated solutions, positioning Veeco for long-term growth. Switching gears to our markets and technologies. As we've discussed in the past, there are four key mega trends driving growth in our three primary markets of semiconductor, compound semiconductor, and data storage. These trends are high-performance computing and AI, mobility, and the immersive user experience, the transformation of the automobile industry, and the cloud. Turning first to the semiconductor market, our strategy is to expand our served available market by delivering differentiated solutions at the leading edge.
We accomplish this with three key technologies. First, our laser annealing product line, which reduces thermal budgets at advanced nodes, is gaining momentum. This is demonstrated by recent orders for additional annealing steps at leading logic customers. We're also seeing traction within the memory market for advanced nodes, which represents a significant long-term growth opportunity for the company. Second, our ion beam deposition system for EUV is another differentiated technology that new and existing customers continue to adopt. These systems are used to manufacture nearly defect-free EUV mask blanks and have been the system of choice for many years. We expect continued demand for our ion beam deposition systems as customers add capacity to support increased adoption of EUV lithography. ASML recently reiterated their plans to ship around 60 EUV lithography systems in 2023.
With approximately 1 of our systems required for every 10 to 15 EUV lithography systems, we size the market at 3 to 5 systems per year. Third, we provide advanced packaging lithography and wet processing solutions to IDMs, foundries, and OSATs. Our lithography systems serve applications such as copper pillar, bumping, redistribution layers, and wafer-level packaging. Our wet processing systems are primarily used for photoresist strip and solvent cleans. As widely reported, the prevailing consensus for wafer fab equipment spend to decline this year by somewhere in the range of 15 to 25%. The forecasted decline is weighted more heavily towards memory than logic. As our semiconductor business is currently more exposed to logic, we remain confident that our semiconductor market sales will outperform WFE spend in 2023.
A few key highlights from Q1 that further support our positive outlook include multiple LSA orders for DRAM devices from a world-leading memory device manufacturer, despite industry-wide CapEx reductions. Additional production orders from our most recent advanced logic customer. Shipment of an advanced-node logic LSA evaluation system for a second application. Further advancement toward an evaluation system over the next quarter for our next-generation annealing solution. We're making progress towards shipping an ion beam deposition evaluation system for low resistivity metals. We expect growth in our LSA and EUV mask blank product lines to more than offset softness in our advanced packaging lithography and wet processing business due to weak consumer electronic demand. As such, we expect our semiconductor revenue to be slightly up in 2023. Now on to the compound semiconductor market.
We primarily serve this market with our wet processing equipment for RF filter and power amplifier devices, along with our epitaxy equipment for power electronics and photonics applications. Our wet processing business has been weak over the last 6 to 9 months due to softness in the smartphone market. Timing of the market recovery is not yet clear. The power electronics and photonics markets offer promising opportunities for growth. In power electronics, we're focused on GaN with our legacy MOCVD technology and with CVD silicon carbide, which we recently acquired. Integration of the acquired CVD technology is progressing well with our system expected to be demo-ready in the second half of 2023. Our system represents a significant opportunity for a differentiated solution to address growing power electronics demand in the electric vehicle market. Our epitaxy equipment to address micro LED applications continues to display promising long-term growth potential.
We're making ongoing investments in this area, including R&D, supporting customer demos, and evaluations to penetrate these market opportunities. Looking at our data storage market. Veeco's ion beam equipment is used to manufacture our customers' magnetic heads. Despite the industry's widely reported challenges, such as excess capacity and inventory, we continue to expect revenue growth in 2023 based on ship dates of orders in our backlog. Taking a step back, the long-term trends in the HDD industry continue to remain promising. According to Gartner and our internal estimates, nearline hard disk drive exabyte shipments are expected to grow at an approximate 25% CAGR over the next five years. In addition, Seagate recently stated they have not let up on executing their heat-assisted magnetic recording or HAMR-based product roadmap and are tracking well to their plan to recognize initial revenue in the Q2 of the year.
Larger drives use more magnetic heads, and newer recording technologies like HAMR use more complex heads. Adoption of this technology offers an opportunity for increased deposition and etch equipment. As such, we remain positive on the long-term opportunity as the industry recovers from its current challenges. Moving on to our 2023 priorities. As always, our first objective is to keep our employees safe and healthy and to promote a culture that prioritizes teamwork and execution. During the quarter, we maintained our commitment to improving our corporate culture by launching our biannual employee survey to assess our progress on key initiatives. We also reiterated our commitment to further improve transparency, diversity, inclusion, and our environmental responsibility by issuing our fourth sustainability report.
In regard to execution, focusing on our supply chain is one of our top priorities, as on-time delivery and quality metrics are essential to maintaining and improving customer satisfaction. Our investments in future innovation and product development are critical to our future success and growth strategy. We'll continue to engage our customers through evaluation system shipments and remain focused on penetrating the rapidly growing silicon carbide market. Lastly, we're focused on outperforming WFE growth expectations with our semiconductor products, which should support us in maintaining profitability levels. With these priorities in mind, we're committed to making a material difference and building a stronger Veeco that serves all stakeholders. With that, I'll turn it over to John.
Thanks Bill. Good afternoon everyone. Today I'll be discussing non-GAAP financial data and would encourage you to refer to our reconciliation between GAAP and non-GAAP results, which you can find in our press release and at the end of the quarterly earnings presentation. Turning to Q1 revenue by market and geography. Revenue totaled $154 million for the quarter, while flat to the prior quarter, coming in above the high end of our guidance. This was driven by sales to our semiconductor customers, which increased 20% year-over-year. Our semiconductor business comprised 60% of total revenue, in line with the prior quarter, with significant contribution coming from our laser annealing product line. The compound semiconductor market contributed 14% of our revenue versus 16% of revenue in the prior quarter. System shipments for photonics applications were the primary contributor of revenue for the quarter.
Moving along, our data storage business totaled 14% of revenue versus 11% of revenue in the prior quarter. Scientific and other made up 12% of our revenue, similar to last quarter. Now looking at quarterly revenue by region. As expected, revenue from China was higher in Q1 as compared to prior quarters, totaling 40% of revenue. This increase was primarily driven by LSA systems to trailing edge customers. While China revenue in Q2 is forecasted to remain elevated, we expect a sequential decline from Q1 and a further decline in the second half of the year. Revenue from our Asia Pacific region, excluding China, totaled 25% of total revenue, led by semiconductor system sales. The United States came in at 20%. Finally, EMEIA was 15% of total revenue for the quarter.
Looking forward to the second half of the year, we expect revenue growth to be led by tier one advanced semiconductor and data storage customers. Switching gears to our non-GAAP quarterly results. Gross margin came in at 41.5%, a decline sequentially from 42.3%, but above the high end of our guidance range. Higher revenue, favorable product mix and operation spending were contributing factors to gross margin for the quarter exceeding our guidance. Operating expenses for the quarter were $43 million, in line with guidance. We continue to be cautious in adding expenses in the current macroeconomic environment while funding our growth initiatives to expand our served available market. Tax expense for the quarter was approximately $3 million, an increase of approximately $2 million from Q4. Post reversal of the valuation allowance, our effective tax rate was 15% in Q1.
Net income came in at $17 million, and EPS was $0.30 on a diluted share count of 63 million shares. Moving to the balance sheet and cash flow highlights. We ended the quarter with cash and short-term investments of $253 million, a sequential decline of $50 million. This reduction was the result of using $30 million of cash for the Epiluvac acquisition and paying $20 million for extinguishing the remaining 2023 notes. Cash flow from operations came in at $14 million, and CapEx was $7 million. From a working capital perspective, our accounts receivable declined by $4 million to $120 million, with DSOs for the quarter declining to 70 days. Accounts payable increased sequentially by $10 million to $62 million, with the corresponding increase in days payable to 62 days.
Inventory increased by $19 million from the prior quarter to $226 million, with days of inventory also increasing to 213 days. This was driven by an increase in inbound materials to support higher expected revenue in the second half of the year and to build a level of safety stock that was depleted as a result of the supply chain challenges. Debt was recorded at $255 million on the balance sheet and represents the carrying value of our $258 million in convertible notes. Turning to Q2 non-GAAP guidance. Q2 revenue is expected to be between $145 to 165 million with gross margin of approximately 42%. We expect OpEx between $44 to 46 million.
Net income between $14 and 20 million and EPS between $0.26 and $0.34 per diluted share. For some additional color beyond Q2. Based on our current backlog and visibility, we reiterate our 2023 revenue outlook of between $630 and 670 million, with growth in the second half of the year. We also continue to target diluted non-GAAP EPS for the full year to be between $1.15 and 1.35 per diluted share. With that, Bill and I will be happy to take your questions. Operator, please open the line.
Thank you. At this time, we will be conducting a question and answer session. If you would like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star two if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. Our first question comes from the line of Tom O'Malley with Barclays. Please proceed with your question.
Hey guys. Good afternoon, and thanks for taking my question and congrats on the good results. I just wanted to walk through, obviously your products have longer lead times but there are certain areas where you can take advantage of some quick turnarounds. Obviously, with the much better numbers, you've seen an improvement a little quicker than you originally expected. Could you just point to the specific areas where you are seeing that improvement? Do you think that's more of a pull forward of demand where people are looking to capitalize in the short term? Or do you see a sustained recovery here, where you've already kind of seen the bottom of this short term downturn? Thank you.
Thanks for the questions Tom. I think as we look at, you know, Q1 as it compared to our initial guide, there were really, you know, 2 things that drove the higher revenue. An additional semiconductor system, LSA system, and an additional data storage system. I would say that, you know, those were on the fence of either happening at the end of Q1 or the beginning of Q2, and we included them in our guide, you know, more or less in happening in Q2. We don't see anything, you know, structurally, you know, changing there, or particularly, you know, in some of the areas where we have, you know, less, less visibility.
I guess I'll just add John, that in the, you mentioned kind of the shorter lead time products like, lithography or wet processing. We aren't seeing any recovery there, particularly in lithography. I will say though that we are starting to have a little more discussions, more encouraging discussions with our customers for projects, either later in the year or in 2024. That's about the first positive thing we've been able to say in litho for, you know, the last 6 to 9 months.
Helpful. I just kind of wanted to square away, the data storage guidance versus what we're seeing in the market. Western Digital's reporting tonight, Seagate already reported and are talking about sequential downtick in HDDs. Seagate mentioned that they wouldn't see a recovery until Q4. Could you talk about, you know, what that means in terms of, you know, capital spend? They've already kind of taken down guidance there, but, you know, are you seeing an additional, wave of weakness from those customers, or are they, you know, still spending on plan versus what you expected entering the year? Thank you.
Yep Tom. I would say clearly we're seeing the softness, you know, that they're having excess capacity and burning down inventory. I would say that's negatively impacting our spare parts and our service revenue business here in the short term, modestly. You know, we'll have to kind of wait and see how that inventory gets burned off and when that happens. Our outlook for the second half increase in data storage is really driven by the orders that we actually have in backlog and are building now for the second half of the year, and we've recently confirmed those ship dates. That's what gives us the ability to have a higher second half.
Helpful. Let me just sneak 1 more in, if I may.
Sure Tom.
... are normally pretty helpful about giving some segment detail into the June quarter. Could you just talk about sequentially through your business segments, what you're expecting to get to the midpoint of guidance? Thank you.
Yes Tom. So you know, we're expecting a fairly similar quarter overall, but some changes in the makeup, you know, by market. We are expecting, you know, semi to be up in Q2, call it closer to the $105 million range. We're looking at, you know, compound semi, you know, in the $25 million range. These are all at the midpoint of our guide. Data storage, as we talked about, the first half we see exactly as we initially planned out, but as I just mentioned earlier, we had one more system shipment in Q1. We now are expecting, you know, Q2 to be more in the $15 million range, but the first half being right on schedule.
scientific we, you know, sort of see in the $10 million range or so in Q2.
Very helpful. Thank you, guys.
You're welcome.
Yeah thanks Tom.
Our next question comes from the line of Rick Schafer with Oppenheimer. Please proceed with your question.
Hi, this is Wei Mok on the line for Rick. Congrats on the quarter and the recent LSA announcement. I believe this is your first entry into the DRAM memory space. I was wondering if you could help us size this market, and how does it compare to the logic market? When do you expect to ship your first system?
Thoughtful question, Wei. I would say we're really excited about the opportunity in DRAM. It's been a fair amount of work to get these follow-on orders. We size, you know, each customer, each application at each step, kind of in the $25 to 35 million range over a 12 to 24 month period of time. We now have 1 customer and 1 application. We expect to start shipping tools, I think, in this quarter right now, the Q2 , and throughout the rest of this year. Hopefully that gives you a little bit of color on that.
Great. Appreciate it. Thank you so much. As for my follow-up, it looks like this equipment, and the design win is going to be manufactured in your new San Jose facility that you expanded into last year. I was just wondering if you can kind of walk through how much capacity do you have at this facility, do you have enough ample space to support this new order?
Yes and yes. So the new space in San Jose, as a reminder, gave us the opportunity in the same overall square foot building to double our manufacturing, or more than double our manufacturing, you know, output. You know, we have not reached that capacity at this point. Yes, for the, for this business that we're planning on, for this year and, you know, going into next year, the San Jose facility has adequate capacity.
Great. Thank you so much.
Mm-hmm.
Our next question comes from the line of Gus Richard with Northland. Please proceed with your question.
thanks for taking the question. just in terms of MOCVD and GaN, I know you've had an evaluation system out there for a while in Asia, and I think you've been talking to customers about, you know, MOCVD for GaN, and I was just wondering if you'd kind of give us an update on what you're seeing in that market and, you know, what's the opportunity over the next, you know, 12 to 18.
Yeah. We do have an evaluation system for GaN power electronics. It's for the transition from 6 inch to 8-inch. The product is running, and we're in a competitive situation there. Our customers asked us to extend that evaluation through this year, which we are going to do. It's a little slower taking off than we had originally planned, and we're still working at it. I would say we probably won't see any meaningful GaN on silicon power activity beyond where we are today until the 2024 timeframe.
That being said we also have GaN on silicon for micro LED, where we're working with a few customers on opportunities there, and that continues to develop as well for GaN on silicon.
Got it. Got it. I think that's it for me. Thanks so much.
Thanks Gus.
Our next question comes from the line of David Duley with Steelhead Securities. Please proceed with your question.
Yeah thanks for taking my question. My first is about LSA. You mentioned you had customers, I guess plural, that you'd won new applications from in the foundry and logic space. I was just wondering if you could elaborate a little bit more about that?
Yeah. In our press release, we used customers because we had follow-on volume orders for our third logic customer. It's a first volume win there in foundry logic. We also had a win in DRAM with multiple tool orders. Those are the 2 customers that we were specifically. 1 for foundry logic and 1 in memory.
Okay, it wasn't 2 new wins in the foundry and logic space?
No, it was 1 new win in foundry logic and 1 in memory.
Okay, great. A little bit topic to silicon carbide. You know, you've made this acquisition, and I thought you talked about, if I'm not mistaken, having a demo later this late this calendar year. Could you help us understand, you know, the size, the market opportunity that you're chasing in the silicon carbide marketplace and who the key competition is for, like this deposition tool, I guess, that you're talking about?
You know, according to Yole, they're sizing the silicon carbide device market at $2 billion going to about $6 billion in 2027, and the corresponding epitaxy equipment market is about $250 million these days, going to about a half a billion by 2027. There are a few participants in that market today, namely, ASMI, and then NuFlare and Aixtron are competitors in that space.
Okay. Was it accurate that you will have a demo later this year, and then when would you expect to have, I guess, meaningful revenue from this particular opportunity?
Yeah. Thanks for, thanks for reminding me of the first half of your question. I would say right now we are shipping our demo tool from Sweden to our demo lab in Somerset, New Jersey as we speak. We're going to be facilitizing it, and our plan is to be demo ready in the second half of the year. We've met with a number of the tier one and tier 2 players in this market. They're all very excited about, you know, the acquired technology with our worldwide service footprint is very intriguing to them. We're pretty much at the key milestone of having to have the demo tool put down films that can be measured and sent to our customers.
We would expect to have eval systems for some tier ones in 2024, and then also start selling directly to some tier two customers as well. I think we're planning for some modest revenue in 24. I think we'd have more meaningful revenue in 2025.
Okay. Thanks for giving me the competitive layout. Who would you say is the leader, in this space now? You know, I would imagine you're gonna have to show a fairly significant cost of ownership advantage versus whoever that leader is. What would be the key reasons that you can show a superior cost of ownership?
Well, the market actually varies pretty significantly by region or what tier. We do understand cost of ownership is critical as well as yields, and yield plays a big part in that. From our discussions with our customers, they do see an opportunity for us to have a cost of ownership advantage over what's available in the market today.
All right. Thanks.
Thanks Dave.
We have reached the end of the question and answer session. I'll now turn the call back over to CEO Bill Miller for closing remarks.
Thank you. I do wanna thank our customers and shareholders, along with the Veeco United team for their continued support as we execute our growth strategy. Have a great evening, everyone. Thank you.
This concludes today's conference, and you may disconnect your lines at this time. Thank you for your participation.
