Analyst · JPMorgan
Thank you, Rick. Please turn to Slide 11 for quarterly financial highlights. KLA delivered a solid quarter in March with revenue at the midpoint and non-GAAP EPS finishing at the upper end of the company's guidance ranges.
Total revenue was $1.424 billion. Non-GAAP gross margin was 61.2%, at the upper end of the guided range for the quarter of 59.5% to 61.5%, driven by a richer product mix than was modeled at the beginning of the quarter. Non-GAAP operating margin was 34.6%. GAAP EPS was $0.50 and non-GAAP EPS was $2.47. At the guided tax planning rate of 13%, EPS would have been $2.52. The reconciliation between the GAAP and non-GAAP EPS includes an impairment of goodwill of $257 million and a $22.5 million loss related to the extinguishment of our November '21 notes that we refinanced in a new bond offering in February.
Let me briefly provide more context on the goodwill impairment. During the March quarter, and consistent with our policy, KLA conducted its annual goodwill impairment assessment based on the discounted cash flows for each reporting unit. Given the uncertainty of the current environment and the associated unknown long-run trajectory of economic growth, we recorded a noncash impairment charge of $257 million in the third quarter to write down a portion of the carrying value of the goodwill associated with the Orbotech acquisition.
Before going into further detail on quarterly results, I want to echo Rick's comments and say that while the COVID-19 situation is unprecedented and presents new challenges to running our business, one thing remains clear. KLA has a resilient business model underpinned by a rock-solid investment-grade balance sheet. We will continue to be agile in the marketplace and actively manage and responsibly navigate our way through this crisis.
Additionally, we remain committed to maintaining our investment-grade credit ratings, and our recent bond offering and refinancing means that we are in a great position and don't have any bond maturities until late 2024. To further expand on that point, I want to highlight that in February, KLA issued $750 million and 3.3% 30-year bonds to redeem $500 million in aggregate principal amount 4.125% senior notes due in November of 2021. And S&P upgraded our credit rating one notch earlier in the quarter to BBB+.
Given our solid balance sheet and consistently robust free cash flow that our business generates, we believe KLA has enough cash and liquidity to respond to any operating condition, while still being able to execute our long-term strategies, invest at a high level in new capabilities across our product portfolio and maintain our well-articulated capital returns approach, which includes our current $3.40 annual per share dividend.
Regarding capital management and deployment, as you would expect, we are reviewing all operating expenses and capital expenditure plans to prioritize and optimize them given the current business conditions and economic environment. One thing is certain. We remain committed to returning 70% or more free cash flow to shareholders over the long term, balanced between dividend payments and share repurchases.
In March, we were consistent with our long-standing capital return framework, returning 113% of quarterly free cash flow to investors, consisting of $133 million in quarterly dividend distributions and $316 million in repurchases of common stock. KLA currently has approximately $1 billion remaining under our share repurchase authorization.
Please turn to Slides 12 and 13 for the breakdown of revenue by segments, end markets, products and regions. Revenue for the Semiconductor Process Control segment, which includes associated service business, was healthy at $1.18 billion. Foundry was once again very strong in March at approximately 55% of Semi Process Control revenue, up from 52% last quarter. Memory was 31% in March, down from 40%. Logic was 14% versus 8% last quarter.
Revenue for the Specialty Semiconductor Process segment was $85 million, up 13% sequentially, driven by strength in RF, MEMS and advanced packaging. PCB, Display and Component Inspection revenue was $160 million, down 14% sequentially and slightly below our internal plans as these businesses, which are closer to consumer markets, softened somewhat as we moved through the quarter.
Now for the breakdown of revenue by major products and regions, starting with the distribution of revenue by major product category. Wafer inspection was 38%. Patterning, which includes reticle inspection, was 21%. Wafer inspection and patterning are part of the Semiconductor Process Control segment. Specialty Semiconductor Process was 5%. PCB, Display and Component Inspection revenue was 7%. Service was 26% of revenue in the quarter and other was 3%.
The regional split of revenue was as follows: China was 25%. Taiwan was 24%. Korea was 21%. The U.S. and Japan were 11% each. Europe, including Israel, was 5%. And the rest of Asia was 3%.
Please turn to Slide 14 for other income statement highlights. Total operating expenses were $378 million, including $215 million of R&D expense. Operating expenses were modestly below our targets for the quarter, with the largest delta to plan coming from lower travel and entertainment expenses and a slower hiring pace than was originally planned. Operating margin was 34.6%. Other income and expense in the March quarter was $38 million.
The non-GAAP tax rate was 14.6% and above the company's long-term tax planning rate of 13% due to negative capital market impact on expense deductions in the company's employee deferred compensation program. Going forward, based on the company's expectations for geographic distribution of profit, you should continue to use 13% as a long-term tax planning rate. Non-GAAP net income was $389 million, and the company had approximately 157 million diluted weighted average shares outstanding.
Turning now to a review of our balance sheet and free cash flow on Slides 15 and 16. KLA ended the quarter with $1.6 billion in cash, total debt of $3.4 billion and a flexible and attractive bond maturity profile supported by investment-grade ratings from all 3 agencies. KLA has a history of consistent free cash flow generation and high free cash flow conversion. Our innovation and differentiation in the marketplace are what drives our industry-leading gross and operating margins and ultimately our free cash flow conversion.
Cash from operations and free cash flow were both strong, coming in at $442 million and $399 million, respectively. Free cash flow margin was 28%, and the annualized free cash flow yield was above 6%. For a frame of reference, over the last 10 years, KLA's free cash flow margin averaged 25%. KLA's business model generates strong free cash flow and is very resilient across the various phases of the business cycle and economic conditions. Over the past 5 years, the company has averaged 98% free cash flow conversion.
Please turn to Slide 17 for a snapshot of our capital return activities. KLA continues to execute on its commitment to return capital to shareholders in the form of both dividends and share repurchases. The dividend payout has increased at a CAGR of approximately 15% since inception 13 years ago. Share repurchases have also increased over the years, with the average price paid to repurchase shares being roughly $73, with approximately $4.1 billion deployed for repurchases since 2010.
Now for our June 2020 guidance on Slide 18. I will start by saying we have mitigated the supply chain issues related to COVID-19 that arose over the past quarter, but fluidity related to this situation makes it a daily challenge to manage as countries around the world handle their respective coronavirus responses. The uncertainties and added complexity associated with global social distancing policies, such as travel restrictions and mandated quarantine periods, continue to pose challenges to our ability to install and support KLA systems.
Accordingly, we have taken extra measures to maintain flexibility and continuity of supply for critical components in our supply chain. Somewhat unique to KLA's business model are longer material lead times and volume hedging strategies that -- to enable flexibility with key components in our products, which slows inventory velocity but allows us to weather short-term disruptions in supply. For short lead time parts, we maintain dual supplier strategies, mostly with suppliers in different countries to optimize capital commitments and ensure we can shift supply to maintain flexibility to meet fluid customer delivery schedules.
In addition, our customers rely on KLA to enable their long-term technology development programs, which tend to be sustained and protected in periods of short-term demand uncertainty and disruption, such as we are currently experiencing. We continue to maintain close ongoing communication with our suppliers to ensure continuity and identify supply chain pressure points, and we remain confident today in our ability to meet our demand and to be able to continue to service and support our customers in the field.
KLA is managing this situation with both determination and creativity. We have fully mobilized our teams and are taking action to minimize disruption in our operations, meet essential customer needs and maintain the resilience of our supply chain to limit the overall impact of COVID-19 across our business.
Given the scale of our worldwide service and support infrastructure, we are supporting our customers with local resources and are executing well. However, it is taking longer in some cases to complete rigorous acceptance criteria for certain products without the support of our factory-centric teams. In all cases, we've done our best to contemplate these factors in our guidance, including the broader range of guidance in our June quarter outlook, which is as follows. Total revenue for the June quarter is expected to be in a range of $1.26 billion to $1.54 billion. Foundry is forecasted to be about 51% of Semi Process Control system revenue, depicting the strength we continue to see amongst our foundry customer base. Memory is expected to be approximately 39%. Logic is expected to be about 10% of Semiconductor Process Control system revenue.
We forecast gross margin to be in a range of 59% to 61% as product mix is modestly less favorable and slightly higher costs are expected in our service business than in the March quarter. Other model assumptions include operating expense of approximately $380 million, interest and other expense of approximately $40 million and a non-GAAP tax rate of approximately 13%.
Finally, GAAP diluted EPS is expected to be in a range of $1.58 to $2.64 and non-GAAP diluted EPS in a range of $1.81 to $2.87. The EPS guidance is based on a fully diluted share count of approximately 156 million shares.
For my financial conclusion, please turn to Slide 19. I'd like to share our perspective on the demand environment for the balance of the year 2020. First, I'd like to address the new export rules published by the U.S. Department of Commerce on April 28, which will go into effect on June 29, 2020. Those rules will expand export license requirements for U.S. companies to sell certain items to companies in China that have operations that could support military end uses even if the item sold by the U.S. companies are used for civilian purposes only.
On this issue, I would note that the new rules do not impact the majority of our business as most of our products are manufactured and assembled outside of the United States. I would also like to point out that we routinely ensure that our products are not used for prohibited military end uses in China. However, the question remains today whether these new rules, when enacted, would make it more difficult to ship to certain customers in China that might be deemed military end users under the new rules as a result of their potential activities supporting military end uses.
We are still assessing the new rules and working with trade associations and others to obtain additional guidance from the U.S. government regarding the scope and practical application of these new rules. Once we have clarity on how these rules will be implemented, we can better determine the impact on our business, if any, in the second half of the calendar year.
Notwithstanding this recent trade issue, our outlook for customer demand in the Semiconductor Process Control business is virtually unchanged today from what we expected in February. As I mentioned earlier, we continue to drive our supply chain in our factories to meet current customer expectations for deliveries. However, we do expect that the overall macroeconomic environment will put pressure at some point on some of our customers' demand for products in certain segments and ultimately could affect their capacity investment plans, both in magnitude and timing.
Obviously, the depth and duration of this impact is unknown today, so we will continue to run our business to maintain the flexibility to respond to any demand scenario. We do expect our customers to continue to progress their technology road maps across all segments, and KLA products are critical to those transitions. We expect investments to continue in this area at a normalized pace, independent of the macro environment.
For our more consumer-centric businesses, we have seen some weakness over the course of the March quarter. And while we are well positioned, we would expect some impact to these businesses compared to what we thought in early February.
Finally, collaboration across global teams and partners on large-scale product development programs without direct in-person engagement is creating some execution challenges, and while early, could put pressure on release dates for new products expected over the next 12 months.
To summarize, as we look ahead to the balance of the year, KLA continues to be well positioned to navigate the uncharted territory we find ourselves in. We derive our strength from our strong balance sheet and liquidity and comfort from not having any bond maturities until late in 2024. Our strong operating performance helps us prioritize critical investments across our technology portfolio and protects our margins while simultaneously generating strong and consistent free cash flow.
Our market position has never been stronger. Despite the usual competitive noise, our share gain and improving process control intensity serve as validation that our products -- our portfolio of products and solutions are adding critical value to our customers' technology road map differentiation and their ability to yield these new technologies at production volumes.
How we allocate capital has never been more important. You can be assured, we will continue to make smart capital allocation decisions, continue to invest in the important R&D to support our customers and new product launches, fuel our long-term growth strategy, maintain our ongoing dividend strategy and preserve our ability to be opportunistic with our buyback program to fully deploy the free cash flow of the company.
Lastly, predictability and business model resiliency matter more now than ever. Our growing diversification, significant exposure to our customers' critical process technology transitions, our subscription-like service revenue stream and our focus on driving operating leverage are key attributes of our business model. We are confident we can continue to excel in managing these areas and position KLA for a brighter future.
Before we begin the Q&A, just a reminder that KLA will participate in many virtual investor webcasted conferences this quarter. Please keep an eye out for notice of future event scheduling, and we look forward to seeing some of you virtually later in the quarter.
With that, I'll turn the call over to Kevin Kessel to begin the Q&A.
