Now, I'll turn the call over to Mr. Eitan Oppenheim, Nova's President and CEO. Eitan, please go ahead.
Thank you, Miri, and welcome everyone to our third quarter financial results conference call. I will start the call today by speaking about our quarterly performance highlights and the market dynamics as they relate to Nova. Following my commentary, Dror will review the financial results in detail and present the guidance for the fourth quarter.
Nova reported another sequential growth quarter. Pursuit of Nova's 1 billion plan and the strong execution of our targets throughout the year, we are confident in the company's long-term performance despite some near-term challenges. Our achievements in the quarter and throughout the year were driven mainly by the unique value we consistently add to our customers and our growing position in the market.
Although some of the traditional industry drivers, like PC and mobile, are showing some near-term weakness, we believe that long-term semiconductor demand will persist, propelled by multiple evolving drivers, which are increasing the heterogeneity of the industry. For our customers, we continue developing our advanced metrology portfolio to capitalize on various horizontal and vertical emerging opportunities in the market.
Our consistent outperformance in the last few years, driven by our unique organic engines and growing market exposure, support our expectations to continue our outperformance beyond the pure demand dynamics, which is expectations, and attained the high end of our guidance, including another sequential quarterly record, which represent around 28% growth year-over-year. Our profitability outcome reached the top end of the guidance, reflecting the efficiency embedded into our operational model as revenue grows.
Highlighting the financial results for the third quarter, and given our guidance for the fourth quarter, we currently aim to grow revenue, continuing to deliver strong outperformance versus CapEx and WFE gross numbers for the year. During the quarter, we also held our Investor Day, in which we discussed at length our new strategic plan to attain $1 billion in revenue in five years.
The plan's fundamentals to achieve growth while strengthening our resiliency and agility. The third quarter underscores a few of those elements. First, the diversity of our customer base is well demonstrated by four major customers this quarter, representing our growing expansion in various leading players. Furthermore, the overall customer mix includes contribution from over 20 active customers across geographies, territories, and even new industry segments like advanced packaging, backend, and PCB.
The second element is the continued diversification of our product portfolio and the adoption of new technologies. While we continue to proliferate our traditional OCD products and set new integrated metrology sales records, we also see growing traction with our new organic growth engines.
During the year, as well as in Q3, we continued the momentum of our SI technology and delivered a growing number of Prism tools, both for R&D and high-volume manufacturing for critical 3D applications.
Today, we see that the Prism capabilities are garnering more advantages as highest aspect ratio applications become more challenging, specifically in memory, where SSD layers are added, nanowires, where 3D structures are fabricated, and TSV formation in front-end and back-end steps.
Since acquiring Ancosys, and based on our growing focus to lead the materials metrology space, we are encouraged by the solid contribution of our materials portfolio to the overall revenue mix this quarter.
While we continue moving our next-generation XPS tools to in-line and in-die measurements, we continue focusing on proliferating the Metrion and ELIPSON systems to additional customers. Specifically, I would like to highlight, as shared in the press release during the quarter, that another logic manufacturer selected Nova's Metrion for next generation IC development.
As part of our material strategy, we are also encouraged by the substantial progress in Ancosys product portfolio introduction in several markets. Based on our Q4 guidance, we now expect a record year for Ancosys, creating multiple growth opportunities for next year as well.
The third area to emphasize in our diversification strategy is the hardening demand in trailing edge nodes and Nova's solid position in this segment. While some IC markets are softening, automotive IoT and industry-related applications remain stable.
The continuous demand for mature generation devices drives new expansions to fulfill the demand. Nova is well-positioned to capitalize on the growing opportunities among these customers, whose contributions represented around 50% of our revenues in this quarter.
Spanning over 4,700 active tools to date in our install base, Nova continues to develop and offer our customers a portfolio of services ranging from ongoing support to new upgrades and productivity packages to keep improving utilization rates, metrology accuracy, and fleet matching. As a result, revenue contribution from services is expected to grow approximately 30% this year.
Before I move on to the market environment and its relevance to our business, I would like to address the latest export restrictions announced by the U.S. government. In October, the U.S. government issued new regulations to restrict some aspects of the U.S. semiconductor trade with China. The regulations are mainly related to export control for advanced node in both memory and logic.
As we continue to evaluate the impact of such restrictions on our U.S.-based activity and global re-export conditions, our initial assessment is that the direct impact on Nova's overall business plan for 2023 is marginal and estimated at around $10 million in direct revenue, mainly from our U.S.-based operations. As the foreign wafer fabrication entities in China acquired their temporary license to continue manufacturing, we continue to carefully monitor domestic customers' investment plan going forward.
Furthermore, while the Chinese market becomes more volatile due to the new trade restrictions, we are encouraged by our growing business in the U.S., which demonstrates significant growth year-over-year. We anticipate this growth to continue next year as well, propelled by both new fabs and new expansions.
Finally, as we look at the industry demand environment, although our long-term growth forecast for the industry remains intact, we expect softness in the near term due to excess inventories driven by a slowdown in consumer electronics demand. The impact on semiconductor pricing, particularly in memory, along with other economic and geopolitical factors, is driving our customers to be more conservative in the near term.
Although we are monitoring these trends carefully and increasing agility in our operating model, over the last few years, we have consistently demonstrated our ability to outperform the industry by proliferating our new technologies, expanding diversification, and market share gains.
Considering all aspects, we remain positive about the company's long-term growth potential and reaffirm the strategic target we introduced on our Analyst Day in September. With that, I would like to recap our third quarter results. Nova had a strong quarter against the backdrop of a dynamic market and an increasingly complex environment.
Given our guidance for the fourth quarter, we are striving to achieve another record growth year for Nova. We believe that the company fundamentals that were strengthened this year will support us in continued outperformance in overcoming interim demand cycles in the years to come. With that, let me hand over the call to Dror David. Dror David?
Thanks, Eitan. Good day, everyone, and thank you for joining our 2022 third quarter conference call. Total revenues in the third quarter of 2022 reached a record, approximately 35% from memory. Product revenues included four major customers and three main territories contributing more than 10% each to product revenues.
Blended gross margin in the third quarter was 57% on a GAAP basis and 58% on a non-GAAP basis. Operating expenses for the quarter were ILS 43 million on a GAAP basis and decreased to ILS 38.5 million on a non-GAAP basis. Operating margins in the third quarter were 27% on a GAAP basis and 31% on a non-GAAP basis at the high end of the company updated target model of 27%-31%. The effective tax rate in the third quarter was approximately 13%.
Earnings per share in the third quarter on a GAAP basis were $1.10 per diluted share, and earnings per share on a non-GAAP basis came in at $1.24 per diluted share. Moving into our guidance for the fourth quarter of 2022, we expect to see a strong finish for an exceptional year, led by the company's diversified exposure to multiple customers, geographies, and manufacturing technologies.
Revenues are expected to range from $99 million to $116 million. Non-GAAP earnings per diluted share are expected to range from $1.15 to $1.32. At the midpoint of our fourth quarter 2022 estimates, we anticipate the following. Gross margins of approximately 57%. Operating expenses on a GAAP basis of approximately $45 million.
Operating expenses on a non-GAAP basis of approximately ILS 40 million. Financial income is expected to increase due to expected higher yields on cash reserves and come in at approximately ILS 2.5 million.
Effective tax rate is expected to be approximately 13%. Moreover, including our fourth quarter guidance, the more than ILS 560 million, reflecting CAGR of 20% across the last five years and reflecting yearly revenue growth of 35% or more in 2022 relative to an expectation of single-digit wafer fab equipment growth in 2022.
Gross margins of approximately 58% and operating margins of approximately 31% on an annual basis. As conclusion to my prepared remarks, I would like to note that the company management is closely monitoring the different scenarios of market demand and customer investment plans for 2023.
To mitigate these different scenarios, the company can activate several mechanisms which can restrain expenses as needed. In addition, the company's cash reserves grew to over ILS 500 million at the end of the third quarter of 2022.
This healthy cash level allows us to continue and execute aggressive growth strategies and infrastructure investments as part of the Nova $1 billion strategic plan, as well as to execute the $100 million share repurchase program, which was recently announced and initiated. With that, I will turn the call back to Eitan. Eitan?
Thank you, Dror. Our prepared remarks are now concluded. We would be happy to take your questions now. Operator?
We will now begin the question and answer session. To ask a question, you may press Star, then one on your telephone keypad. If you're using a speaker phone, please pick up your handset before pressing the keys. To withdraw your question, please press Star then two. The first question comes from Vivek Arya of Bank of America. Please go ahead.
Hi. Thanks for taking the question. This is Duksen Jang on behalf of Vivek Arya. Congrats on the quarter. I know you said you outgrew WFE in 2022, but for next year, there seems to be a difference between a lot of your peers, KLA and Lam suggesting that it's gonna be down 20%, whereas ASML suggesting their sales can grow. Which one do you think is more indicative of your performance next year? Thank you.
Thank you for the question. As you know, we don't guide beyond the current quarter, and in this current environment, in this current timing, it will not be so responsible to forecast the full year. I can relate, though, to the market environment, and as I said in my prepared remarks, we are expecting volatility due to softness in memory, which, by the way, we think will start to normalize and recover in the H2 of 2023, where bit demand will grow along with price stabilization.
As mentioned a couple of times in my script, the agility and diversity that we have built in our business model, along with the adoption of our newly introduced technologies and the growing expansion in several markets, should support our consistency and outperformance beyond pure semiconductor demand.
I think that if we look at Nova, there are, besides the pure demand calculation, supply demand calculation, everybody understand is volatile next year. We also benefiting from some expansions in R&D line, some new fabs that are coming in play, penetration into the materials world with new technologies, as well as expanding our portfolio to other markets. Overall, we think that we are more resilient to the market volatility, and as I said before, we hope to outperform the market.
Great. As a follow-up, I know on the Analyst Day you mentioned services will be on track to reach $100 million this year. How resilient is that business into that downturn next year? Also, thanks for the color on the $10 million from the Chinese restrictions impact. Have you noticed any cancellations or order push-outs with regards to that?
Regarding the services, obviously the installed base of the company is growing. We currently have approximately 4,700 tools in service installed base, and this will continue to grow in Q4 and the following quarters.
As a result, we continue to expect to see growth in service revenues also in 2023. Now regarding the second part of the question about China. It's when we're looking right now in the Chinese market. We look at the trade restriction that came from the US in regard to advanced nodes in both DRAM, Flash NAND, and also the logic.
Our estimation for those restrictions that are coming out from the US, because this is the restriction that we are part of, is around $10 million. This is the direct one. Basically for our XPS tools that are shipped from the US. We don't have any currently direct impact on the rest of the shipment. Nevertheless, we cannot estimate right now if something will happen indirectly.
Meaning if, for example, other process tools cannot ship their tools and therefore some of the line will be slowed down and therefore they don't need metrology. This one we cannot estimate currently the impact. I just want to say that most of the revenues of the company in China are coming from trailing nodes that are not part of the restriction on advanced chip manufacturing. Overall, we think that the overall impact on the company will be anyway marginal.
Great. Thank you so much.
As a reminder, if you have a question, please press star one. Seeing that there are no further questions in the queue, I would like to turn the conference back to Eitan Oppenheim, President and CEO, for closing remarks.
Thank you, operator, and thank you all for joining our call today. Thanks.
The conference is now concluded. Thank you for attending today's presentation. You may now disconnect.
