Good day, everyone, welcome to this Microchip Technology fourth quarter and fiscal year 2018 financial results conference call. As a reminder, today's call is being recorded. At this time, I would like to turn the call over to Microchip's President and Chief Executive Officer, Mr. Steve Sanghi. Please go ahead, sir.
Thank you. I'd like to turn the call to Eric Bjornholt, Chief Financial Officer first. Eric, go ahead.
Okay. Good morning, everybody. During the course of this conference call, we will be making projections and other forward-looking statements regarding future events or the future financial performance of the company. We wish to caution you that such statements are predictions and that actual events or results may differ materially. We refer you to our press releases of today, as well as our recent filings with the SEC that identify important risk factors that may impact Microchip's business and results of operations. In attendance with me today are Steve Sanghi, Microchip's Chairman and CEO, and Ganesh Moorthy, Microchip's President and COO. I will comment on our fourth quarter and full fiscal year 2018 financial performance, Steve and Ganesh will then give their comments on the results, discuss the current business environment, as well as our guidance, and make some specific comments on the pending acquisition of Microsemi.
We will be available to respond to specific investor analyst questions. I want to remind you that we are including information in our press release and this conference call on various GAAP and non-GAAP measures. We have posted a full GAAP to non-GAAP reconciliation on the investor relations page of our website at www.microchip.com, which we believe you will find useful when comparing GAAP and non-GAAP results. I will now go through some of the operating results, including net sales, gross margin, and operating expenses. I will be referring to these results on a non-GAAP basis, prior to the effects of our acquisition activities and share-based compensation. Non-GAAP net sales in the March quarter were just over $1 billion, above the high end of our guidance and up 0.8% sequentially from net sales of $994.2 million in the immediately preceding quarter.
We have posted a summary of our revenue by product line and geography on our website for your reference. On a non-GAAP basis, gross margins were at the high end of our guidance at 61.7%, which is a new record level for Microchip. Non-GAAP operating expenses were 22.2% of sales, Non-GAAP operating income was a record 39.5%. Non-GAAP net income was a record $351.3 million, resulting in earnings per diluted share of $1.40, which was above the high end of our guidance of $1.37. Non-GAAP EPS in the March 2018 quarter was up 20.7% compared to the March quarter of 2017. For fiscal year 2018, on a non-GAAP basis, net sales were a record $3.981 billion and up 13.7% year-over-year. Gross margins were 61.1%, operating expenses were 22.4% of sales, and operating income was 38.7% of sales.
Net income was $1.356 billion, and non-GAAP EPS was $5.45 per diluted share. On a GAAP basis, gross margins in the March 2018 quarter, including share-based compensation and acquisition related expenses, were 61.4%. GAAP gross margins include the impact of $3.3 million of share-based compensation. Total operating expenses were $371 million and include acquisition intangible amortization of $122.8 million, share-based compensation of $20 million, $5.2 million of acquisition related and other costs, and special charges of $0.2 million. GAAP net income in the quarter was $146.7 million, or $0.58 per diluted share, and was impacted by a couple of discrete events in the quarter. GAAP net income was impacted by a $15.5 million charge associated with marking our investments to market through the P&L.
Since the investments used to be held to maturity, but since the investments will be liquidated to fund the acquisition of Microsemi, the unrealized loss that would have been recorded in other comprehensive income in the absence of the anticipated acquisition was recognized in earnings. GAAP net income was also impacted by $38.9 million of discrete tax expense during the quarter, primarily associated with the Tax Cuts and Jobs Act. For fiscal year 2018, net sales were a record $3.98 billion. Gross margins were 60.8%. Operating expenses were 37.3% of sales, and operating income was 23.5% of sales. Net income of $255.4 million was $1.03 per diluted share. The non-GAAP tax rate was 8.4% in the March quarter.
As we have continued to evaluate the impact of the Tax Cuts and Jobs Act, we are now expecting about $327 million of taxes to be paid over the 8 years related to the tax incurred on foreign earnings that were permanently invested offshore, referred to as the transition tax. This estimate is up modestly from what we had discussed with investors last quarter. We estimate the tax payments to be approximately $26 million in years one through five, $49 million in year six, $65 million in year seven, and $82 million in year eight. We will continue to evaluate the impact of the Tax Cuts and Jobs Act, These estimates may change as we complete our full analysis.
As we look forward, excluding the transition tax from the Tax Cuts and Jobs Act, we expect our ongoing long-term cash tax rate to be between 8% and 9%, which is what we are providing to investors for cash flow and non-GAAP operating model forecasting purposes. Moving on to the balance sheet. Our inventory balance at March 31st, 2018, was $476.2 million. Microchip had 112 days of inventory at March 31st, 2018, down three days from the end of the December quarter. Inventory at our distributors was at 36 days and up two days from the December quarter. The cash flow from operating activities was $359.6 million in the March quarter. As of March 31st, the consolidated cash and total investment position was $2.197 billion, of which over $700 million is domestic cash.
Due to the Tax Cuts and Jobs Act, the majority of our offshore cash can be brought back to the U.S. without incurring any material additional tax cost. Our EBITDA in the March 2018 quarter was a record $429.6 million. Our net leverage, excluding our 2037 convertible debentures, was 0.95 at March 31st, 2018, positioning us well for the Microsemi acquisition. Capital expenditures were $58.4 million in the March 2018 quarter and $206.8 million for fiscal year 2018. In April, we completed a purchase of a building in San Jose for $40.8 million, which we had previously leased. This purchase will reduce our ongoing operating expenses. Excluding this building purchase, we expect about $30 million-$50 million in capital spending in the June quarter.
We expect capital expenditures for fiscal year 2019 to be between $200 million and $250 million, of which $70 million represents the San Jose building purchase and three other buildings being constructed, which we have discussed with you before. We are aggressively adding capital to support the growth of our production capabilities for our fast-growing new products and technologies, and to bring in-house more of the assembly and test operations that are currently outsourced. These capital investments will bring significant gross margin improvement to our business, particularly for the Atmel manufacturing activities that we are bringing into our own factories. Depreciation expense in the March quarter was $32.8 million. I will now ask Ganesh to give us comments on the performance of the business in the March quarter. Ganesh?
Thank you, Eric, and good morning, everyone. We performed better than we expected in the seasonally slower March quarter, with a sequential revenue growth of 0.8%. March quarter 2018 revenue over March quarter 2017 revenue grew 11%, all organic growth, as there was no contribution from acquisitions in the last four quarters. On a fiscal year basis, fiscal year 2018 revenue grew a strong 13.7% over fiscal year 2017. The Microchip 2.0 transformation continues to make good progress, especially in terms of new design opportunities as we enable our clients' innovation with the very best smart, connected, and secure solutions. Taking a closer look at microcontrollers. Our microcontroller businesses performed well for our March quarter, with revenue down sequentially only 0.6% as compared to the December quarter. March quarter 2018 revenue was up a very strong 13.2% over March quarter 2017.
On a fiscal year basis, fiscal year 2018 microcontroller revenue at $2.6 billion was an all-time record and grew a strong 17.5% over fiscal year 2017. Microcontrollers represented 65.6% of Microchip's overall revenue in the March quarter. Last month, Gartner Dataquest released their microcontroller market share report for calendar 2017. We are pleased to report that Microchip retained the number 1 position for 8-bit microcontrollers. We were the fastest growing 8-bit microcontroller franchise and gained substantial market share in calendar 2017, as we grew much faster than the 8-bit microcontroller market. So much so, we are now approximately 60% larger than the number 2 8-bit microcontroller player. In the 16-bit microcontroller market, we remained in the number 5 position but continued to gain significant market share as we grew much faster than the 16-bit microcontroller market and were the fastest-growing franchise.
In the 32-bit microcontroller market, we remained in the number 6 position but also gained significant market share as we grew much faster than the 32-bit microcontroller market and were the fastest-growing franchise here too. For microcontrollers overall, we remained in the number 3 position, were the fastest-growing franchise, and grew at almost 2.5 times the microcontroller market as we continued our relentless march towards the number 1 spot. Our microcontroller portfolio and roadmap has never been stronger, and we are seeing continued growth in our design-in funnel, which we expect will drive future growth as these designs progress into production over time. We believe we have the new product momentum and customer engagement to continue to gain even more share in 2018 as we further build the best performing microcontroller franchise in the industry. Now moving to our analog business.
Our analog revenue was sequentially up 4.7% in the March quarter as compared to the December quarter, setting a new record in the process. March quarter 2018 analog revenue grew 5.1% over March quarter 2017. On a fiscal year basis, fiscal year 2018 analog revenue at $952 million was an all-time record and grew 6% over fiscal year 2017. Analog represented 24.2% of Microchip's overall revenue in the March quarter. As we have highlighted in investor communications over the last few quarters, our publicly reported analog results will see some revenue classification headwinds resulting from a deliberate shift in strategy we made several quarters ago. The change in product line strategy is that we have, for some time, been adding microcontroller cores to several of our more complex analog products, especially those that provide our clients with smart connectivity solutions.
The addition of microcontroller cores to these analog products enables us to sell a higher value and more defensible total system solution. These smart connectivity products are growing nicely, and as they replace older products in new designs, our revenue classification for these products has shifted from analog product line to our microcontroller product line. Transitioning to more sticky and higher margin smart connectivity revenue is the right Microchip answer, but does impact some of the product line reporting that analysts are interested in, as some of the revenue growth shifts into our microcontroller product line. In the longer term, as the revenue from the analog attached design wins continue to ramp, we fully expect that the analog product line revenue will outgrow this revenue classification headwind. Moving next to our licensing business.
This business was seasonally down 4% sequentially in the March quarter, although March quarter 2018 revenue grew 14.6% over March quarter 2017. On a fiscal year basis, fiscal year 2018 licensing business at $104.8 million, was an all-time record and grew 14.9% over fiscal year 2017. We are seeing the fruits of having licensed many foundries and independent device makers for several years on multiple process technology nodes, manifest in our results as the licensed processes ramp volume and generate royalty revenue for many years to come. Finally, our memory business was sequentially up 3.8% in the March quarter as compared to the December quarter. March quarter 2018 grew 9.9% over March quarter 2017. On a fiscal year basis, our fiscal 2018 memory revenue at $199.7 million grew 7.2% over fiscal year 2017. Now a quick update about Microsemi and our progress since our March 1st announcement.
Integration planning meetings and discussions are occurring between the business units, sales, manufacturing, and support groups of both companies. Teams at both companies have started to identify product cross-selling opportunities that we can pursue after the close and have also identified reference designs that can take advantage of our combined total system approach. We're also determining how our product line reporting will be done post the close, and we'll have an update for you no later than the next earnings call. Steve will cover the status of regulatory and other approvals in his section. Now let me pass it to Steve for some comments about our business and our guidance going forward. Steve?
Thank you, Ganesh, and good morning for you everyone. Today, I would like to first reflect on the results of the fiscal fourth quarter of 2018 and fiscal year 2018. I will then provide guidance for the fiscal first quarter of 2019. Our March quarter financial results were excellent. Our net sales were up 0.8% sequentially and up 11% from a year ago quarter and were above the high end of our revised guidance. The sales in our Atmel-originated business was down, consistent with Atmel seasonality. Our core Microchip business was very strong and up significantly sequentially. Our non-GAAP gross margin of 61.7% of sales was a record and at the high end of our guidance.
Operating profit of 39.5% of sales was better than the high end of our guidance and made a new all-time record, and earnings per share of $1.40 was $0.055 better than the midpoint of our revised guidance. Reflecting on the fiscal year 2018 results, it was clearly the best year in the history of Microchip, in which we made many new records. Fiscal year 2018 net sales were up 13.7% from fiscal year 2017, and it was all organic growth. I want to thank all the employees of Microchip worldwide for delivering an outstanding quarter and fiscal year 2018. On non-GAAP basis, this was also our 110th consecutive profitable quarter. Now I will provide you with an update on Microchip 2.0. We are continuing to experience an enormous customer preference to design with our microcontroller solutions in all 8-bit, 16-bit, and 32-bit customer applications.
Our various acquisitions have now built a powerful, diversified product line through which we are able to provide total system solutions to our customers. We are winning incremental design wins with multiple products in the same boards of our customers. At our Analyst and Investor Day on March 1, 2018, we showed that the number of Microchip parts per customer system was growing at 20% annual rate. With another quarter under our belt, the number of parts per system is continuing this trend of being up 20% over the same quarter a year ago. We have a robust design win funnel, and we feel very optimistic that Microchip 2.0 is working. We also recently received SIA numbers for quarter ending March 31, 2018.
Based on SIA numbers, our microcontroller market share grew in each of 8 bit, 16 bit, and 32 bit product lines in March 2018 quarter versus a year ago quarter. Our inventories at Microchip at the end of March 2018 were 112 days, which is just slightly below our target of 115 to 120 days. We continue to make enormous progress on the manufacturing side and bringing capacity online and decreasing lead times. In the last conference call, we stated our lead times to be between 4-14 weeks. Our lead times now are between 4-10 weeks. Normal lead times would be between 4-8 weeks. Our book-to-bill ratio for March quarter was extremely healthy and around the number we had given you at the Analyst Day, and our backlog has gone even higher to another record.
With healthy book-to-bill ratio continuing, now will be the time to stop providing quarterly numbers for book-to-bill ratio as we had said in the Analyst Day. We have always said that book-to-bill ratio is confusing and simply tracks the lead times. We have proven it again with book-to-bill ratio of 1.0 in December quarter, the business remained healthy in March quarter. Providing book-to-bill ratio simply increases volatility in the stock. In the March quarter, we successfully soft landed the business consistent with the guidance we have been providing, and we will continue to grow in the June quarter. During the quarter ending June 30, 2018, we will adopt a new GAAP revenue recognition standard which will result in recognition of revenue at the time products are sold to distributors, whereas currently, revenue on such transactions are deferred until the product is sold by our distributors to an end customer.
We are not able to provide guidance on a GAAP basis as we are not able to predict whether inventory at our distributors will increase or decrease in relation to end market demand, and this is not how we manage our business. As evidence of this uncertainty in recent years, we have seen net inventory at our distributors increase or decrease by a significant amount in a single quarter. Our non-GAAP revenue will be based on true end market demand. We will report a non-GAAP revenue, which will be based on true end market demand in which we measure the revenue based on when the product is sold by our distributors to an end customer, meaning we will continue to report a non-GAAP revenue based on sell-through. We will continue to manage our business and distributor relationships based on such sell-through revenue recognition.
All of Microchip's bonus programs will continue to work based on sell-through revenue recognition. Therefore, along with GAAP results, which will be based on sell-in, we will also report our non-GAAP results based on sell-through revenue recognition. In terms of guidance, we will only provide guidance based on non-GAAP revenue. We expect total non-GAAP net revenue for the June quarter to be up 1%-6% sequentially, giving us a midpoint of the guidance at 3.5%. Given the amount of revenue beat in March quarter, this guidance is modestly better than the expectation we had provided during the Analyst Day. Regarding gross margin, we see a steady improvement in overall gross margin of the company based on Microchip 2.0 margin drivers. We expect gross margin for the June quarter to be between 61.6%-62% of sales.
We expect overall operating expenses to be between 22%-22.4% of sales. We expect operating profit percentage to be between 39.2%-40% of sales. We expect earnings per share to be between $1.39-$1.49 per share. All these numbers do not include Microsemi. Now, I wanted to make a couple of comments on the pending acquisition of Microsemi. On April 12, 2018, we received a U.S. antitrust clearance. On April 19 of 2018, China's MOFCOM accepted Microchip's filing for review under simplified procedure. We cannot confirm yesterday's report in the press that China's MOFCOM has cleared the transaction. We believe that review process is running smoothly, and we remain optimistic that we will receive clearance shortly. In addition, yesterday on May 7th, we did receive Japan's antitrust clearance. We expect several other countries to clear their antitrust review this month.
The Microsemi shareholder vote is scheduled for May 22, 2018, and we believe that we are on schedule for closing the acquisition sometime during early June 2018. I want to remind investors that during our analyst and investor day presentations, we increased our long-term financial model with the Microsemi acquisition to a non-GAAP gross margin of 63%, operating expense of 22.5%, and an operating profit of 40.5%. As you all know, we will be borrowing about $8 billion to close the Microsemi transaction. I want to assure you that after the closure of Microsemi acquisition, we plan to use all of our cash generation, after dividend and capital, of course, to rapidly de-lever the balance sheet until the leverage comes down to about 2.5x, which is our long-term target.
In addition, given all the complications of accounting for the acquisitions, including amortization of intangibles, restructuring charges, and inventory write-up on acquisitions, Microchip will continue to provide guidance and track its results on a non-GAAP basis. We believe that non-GAAP results provide more meaningful comparison to prior quarters, and we request that the analysts continue to report their non-GAAP estimates to First Call. With this, operator, will you please poll for questions?
Thank you. If you would like to ask a question, please signal by pressing *1 on your telephone keypad. If you are using a speakerphone, please make sure your mute function is turned off to allow your signal to reach our equipment. Due to time constraints, we ask that participants please limit themselves to one question. If you do have additional questions, you may rejoin the queue. Again, it is *1 if you would like to ask a question, and we will take our first question from William Stein with SunTrust. Please go ahead.
Great. Thanks so much for taking my question. You highlighted earlier in your prepared remarks that you've added capacity, I think as it related to the Atmel products to reduce the lead times there. I'm wondering if you can talk about your anticipation for lead times as we go forward. Do you expect that to get in the normal range in the current quarter? I'd also like to know as it relates to your raw materials and lead time from foundries, whether you see that as already within the normal range or if it's extended, and if there's anything remarkable about that, I'd love to hear details. Thank you very much.
Thank you, Will. The normal lead times are 4-8 weeks, usually on 85%, 90% of the products. That's what we call a normal lead time. There'll always be some strange products or specialized projects that need extra work or strange circumstances where the lead time would be longer. For a majority of the products, 4-8 weeks lead time is normal. We are currently at 4-10, we got a little more progress to make. As we have been saying for about a year or longer, is that we expect the lead times to essentially become normal by the end of June, and we are really on schedule for that. The other part of your question was lead times at suppliers and foundries and all that. Scattered issues here and there, but in general, the foundry lead times are normal.
We're able to get the capacity we need from our foundries. We're able to get the assembly test equipment that we're acquiring. Again, the lead time could be 2-4 weeks longer to get some of the test equipment, but it also largely depends on what you're buying and what the mix of equipment is, what you're trying to buy, and what particular setup you need. Lead times are really not excessive, either on foundry wafers or on assembly test equipment.
Helpful. Thanks so much, and congrats on the good results and outlook.
Thanks.
Our next question comes from Craig Hettenbach with Morgan Stanley. Please go ahead.
Yes, thank you. Steve, any update on industry pricing, be it from some of the consolidations, some of the favorable impact there, also relative to just the tight conditions today and how that might be influencing pricing?
Sorry, for what?
The pricing environment today. If you can talk about just how the consolidation in the industry is influencing that, as well as just the tight industry conditions?
Okay. Tight industry condition. The pricing is very normal. We've been saying for quite a while that the historic industry practice, where the prices went down every year, we are really no longer following that trend. We have seen some others follow it. We are winning a lot more often at customers, not giving them year-to-year price reduction. Five years ago, we'll succeed some of the times. Today, we succeed most of the time. Industry pricing for us really looks very normal. We did some price increases in the last two years. I think that's kind of largely behind us now. Prices are stable, but they're not going down. Meanwhile, we are continuing to improve cost on a lot of products by bringing assembly test inside with die shrinks and others. In those cases, some of those are improving the gross margin as you're seeing it.
In terms of tight industry conditions, they are obviously helping pricing. The consolidation is also helping prices. Where the industry conditions are tightest are really not on microcontroller, analog, and Wi-Fi, and other products we make. Industry conditions are the tightest on passives. There could be 40, 50 weeks lead time to really get capacitors and products like that. I think that's where we are seeing price increases. We don't sell those devices. We don't compete with them. We buy some of those devices for our development tool and all that. It's not a very high cost component for us, because development tool is a very small business. We are seeing long lead times and tight supply, especially on passives.
Got it. Thanks for sharing that. Just a follow-up for Ganesh on the Microchip 2.0 kind of cross-selling, and any additional milestones you can share with us on the progress you're making?
All our internal indicators look good. As Steve mentioned, attach is one of those things we are continuing to measure how that is growing quarter-over-quarter, year-over-year. It's a long-term process, but you're sowing lots of seeds and taking care of those seeds to make sure that they bloom. We're very confident that it will continue to grow and provide growth for us as an incremental growth driver.
Got it. Thanks.
Our next question comes from Mark Delaney with Goldman Sachs. Please go ahead.
Good morning. Thanks for taking the question. I realize Microchip's own inventory came down and is a little bit below your target range. I was hoping you could extend that discussion a bit further and talk about where you think inventory is in the channel and any changes that you expect distributors to be making with their inventory.
The inventory was a little lower than our expectation because sales were higher than our expectation. Our guidance at the midpoint was on a minus 1% sequentially, based on that, the inventory would be slightly higher and in the range of 115 to 120 days. Instead, we reported sales which were up a 0.8%, so 1.8% beat. Its net result was the inventory in days was slightly lower. I think inventory is fine. Two, three days don't really make that kind of difference. We are comfortable with the inventory position. Inventory, there are always products which are short and the product which are a little high, so there is a continuous effort constantly to get the inventory in the perfect mix, and there is no such thing as perfect, but our inventory is in good shape.
Okay, that's helpful. There's a lot of discussion in the last earnings call and at the Analyst Day about what new seasonality for the company is. I was hoping you could help us better contextualize how you think about the guidance for this coming quarter of up 1% to 6% sequentially. How does that compare to what that new seasonality may be? Are there any headwinds or tailwinds relative to normal seasonality that you're trying to factor into your guidance for this coming quarter?
I think, at the Analyst Day, we said June quarter was 5%, if you recall, sequentially, we beat the March quarter by 1.8%. When you put it all together at the 3.5%, we're slightly better than that guidance. We did better in manufacturing last quarter in shipping some delinquency that originally we thought we're going to ship it in the June quarter, we were able to do better and were able to ship some more in the March quarter, which resulted beating the March quarter and then a little bit of the product went from June into March. We're facing a lot of one-time issues. There is a slight impact because of ZTE. We can't ship to ZTE. There are long lead times on passives that we talked about.
Certain customers are telling us that they don't need our product because they cannot get passives to complete their boards and systems. China VAT has been lowered from 17% to 16%. Doesn't sound much, sounds trivial, a number of customers asked us to delay shipment from April into May because the lower VAT was effective on May 1. That pushed some shipments from April into May, that's kind of a wash for the quarter. You never know whether they didn't do some production in April and whether there'll be any net result for the quarter. Hopefully not. The overall trade tensions, we're not seeing any impact of that, if anything else crazy happens, you have to account for that. None of those items I talked about really are significant.
They're all 0.1%, 0.2% kind of issues sequentially, but you add all four or five of them and it could be in a half a percent to 1% probably impact driven by many of these factors together. I think what we guided June quarter is really seasonal, especially if March quarter was minus one, then the June quarter would have been totally seasonal. We don't have years of experience with Atmel in our numbers for that seasonality, but what we're guiding seems to be close to seasonal. The other point is, this is all going to change again when the Microsemi deal closes in June, then all the rest of the quarters, again, we don't have experience on seasonality. When we come to the next March and next June, we're going to have to go through the same learning process again.
We barely finished that learning process on Atmel. That is the challenge of growth through acquisition.
We will take our next question.
Does that answer your question?
Thanks so much.
We will take our next question from Craig Ellis with B. Riley FBR. Please go ahead.
Thank you for taking the question, and congratulations on the nice execution. Steve, I wanted to start with two clarifications. One, if you could provide any color for us on whether this round of approvals, especially through MOFCOM, is different than what you've seen in the past. Secondly, I thought I heard the statement that the company expected to borrow about $8 billion related to the upcoming Microsemi transaction, but I thought on initial announcement it was $8.6 billion. Has there been a modest reduction in the expected debt that's undertaken to complete that transaction?
Answering your second part of your question first, the number that we had stated was really going off the December numbers. From December to June, we are a substantially cash-generating entity. We have generated half a billion dollar plus of cash in that time, and so has Microsemi. There's a portion reduction coming from there. I think that's the only change. Eric, you want to add anything to that?
No, that's exactly right. That essentially just represents the cash flow between the end of December and the expected closing date.
The debt level that Microsemi has is a bit lower from what was at that time. They have paid some debt down.
That's helpful. Any color on how this process through MOFCOM would differ from prior?
Last time we had MOFCOM approval was when we bought Microsemi, which was in 2012. At that time, MOFCOM didn't have a lot of resources. The M&A activity wasn't as brisk, and it was largely few deals used to require MOFCOM, and it was kind of a long process, seemed relatively unorganized back then. Any of the deals we have done in between, including ISSC, Supertex, Micrel, and Atmel, none of them required MOFCOM. You require MOFCOM if both entities, buyer and the seller, exceed a threshold of revenue in mainland China. I think the number is $83.6 million, but don't exactly hold me to it. It's in that range. None of our other acquisitions have required MOFCOM.
Since 2012, this is the first time we applied for MOFCOM, and we have found that MOFCOM is now substantially very well organized, have a very good procedure. They take the first month to identify a given transaction to be a simple procedure or a normal procedure. A simple procedure usually is cleared within 30 days, and a normal procedure takes a little longer. That's why when our transaction was rated by MOFCOM to be under simple procedure, that was encouraging news, and we shared it with the investors. That happened on April 19, so 30 days really end on May 18. Now, there's no guarantee that even under a simple procedure, you get it on that day or not, or it takes longer or any new questions emerge.
We're pretty optimistic that this is going very smooth, and we should be getting approval very rapidly here.
That's very helpful. If I could ask one question to either you or Ganesh. Impressive performance with Microchip 2.0 initiatives driving a 20% increase in parts per system board. As you look ahead to Microsemi, how does Microsemi impact that growth rate on your design wins on a per system board basis? Thanks, guys.
Go ahead, Ganesh.
It's early days. What we are very encouraged by is the methodology that Microsemi uses for their equivalent of total system solutions. I showed some examples during the Investor Day on March 1st, and they have an extremely well-organized approach of how to take products from multiple business units and position them into the end markets that they're providing solutions for. In the early discussions between the two companies, we have both identified places where each other's products can further strengthen those demo boards or reference designs or customer propositions that we can get. It's too early to tell you what the rate will be, but I am very encouraged by how the approach is common, and the employees of the two companies are looking for ways to exploit that further after the close.
Great. Thanks again.
Our next question comes from Christopher Danely with Citigroup. Please go ahead.
Hey, thanks, guys. Steve, now that we're kind of working through the June quarter, can you just give us your best guess of combined seasonality for you guys plus Atmel for the September and December quarters? Then also maybe compare this deceleration that we've just seen versus the deceleration that occurred at the end of 2014.
I think I don't really have numerical numbers for all the quarters for seasonality. I believe that December and March quarters continue to be weak quarters, and June and September continue to be strong quarters. We're guiding good sequential growth in June, and I would expect the same thing for September. December is usually the weakest quarter for the combined companies. March also, driven by the Atmel seasonality, is slightly negative, although this quarter we just announced was slightly positive. I don't think that has changed. Strong June, strong September, weakest December and a weak March. Mind you, this is all going to change with Microsemi, whose seasonality we do not understand yet. The second part of your question was what?
Yeah, just compare the deceleration that we've seen with lead times coming in to what happened in 2014. We had a deceleration back then. It was obviously a little bit sharper, but it seems like the time period was roughly the same. Would you agree with that?
Well, 2014 deceleration was driven by significant slowdown in China that everybody saw. I don't recall what caused that. I think there were some government regulations changed. They reduced some of the subsidies from the various markets. There were a lot of things, it was so clearly driven by China. This deceleration is not driven by any place. World economies are synchronously going up, I think the business environment is pretty good worldwide. This is just as the longer lead times are coming in, basically business is going back to normal. I don't really think it's at all like the 2014.
Okay, thanks. That's helpful.
Yeah. Investors and analysts have been trying to compare this to 2014. Ever since we put the letter out on April last year, that has been the talk, everybody trying to compare it to 2014, and it's nothing like 2014. We've been telling you that this will soft land, and I think you got to give it to me that we have soft landed it completely.
Our next question comes from Harsh Kumar with Piper Jaffray. Please go ahead.
Hey, thank you, Steve. Congratulations. Excellent results. Perfect segue into my question. Now that the soft landing, I think you said, is complete, would you give us an idea of what you're thinking in terms of just your part of the business, not MSCC, but just your part of the business and how it plays out as far as growth is concerned? I have a question that's follow-up.
Well, I think it's the same question I just answered. Strong June, strong September. You should see good results from us for this quarter and the next quarter, and then we go into a slow December and slow March. I think the numbers we have talked about before, mid to high single digit kind of growth, I think that's where we are, and that's what the current guidance is, and I think the business has gone to normal after soft landing.
Okay, fair enough, Steve. Then your MCU business is pretty strong. I think you mentioned two and a half times the growth rate. A lot of the large players play in the same markets as you. Everybody's targeting industrial automotive, but you guys are doing substantially better. Is share take all of it, or are there other things going on, Steve, in your opinion?
Go ahead, Ganesh, you want to take that?
A substantial portion of it is taking share. I think we're also consistent in an approach that isn't picking, we're only going to do 32 bits and not focus on others. We are broad-based between eight, 16s and 32s. We find the spots that each of them succeed in. Each of them is growing. They're setting new records as they're growing. That breadth of what we have in solutions, how we go to market, in many ways differentiates us from other people who may have a little different way of how they want to go to market. I think the results show that. Year in and year out, the market share has been growing, the position in that ranking has been growing.
I think there's no one silver bullet that's causing it, but our approach and go-to market across the microcontrollers is contributing to the differentiated results of microcontrollers.
Thanks, guys.
I would add to that, Harsh, that we are rapidly being perceived as the most reliable microcontroller supplier. They have seen significant challenges in delivery and other problems from our competitors, both in Japan and Europe, and you know the names of those companies. Those companies have discontinued or end-of-life'd a large number of products from some of the companies they have merged with and created significant havoc at the customers. The other company that is in play right now, waiting for the China MOFCOM, they have seen significant dislocation, or the customers have seen inconsistent supply and challenges. Microchip absorbed a very large acquisition of Atmel and other companies we have bought before. What we have done for the customers and Not end-of-life to any of the microcontrollers. The customers have a very positive experience with us through all that.
I think we are the preferred supplier, that's why.
Congratulations, guys. Thank you.
Thanks.
Our next question comes from Rajvindra Gill with Needham & Company. Please go ahead.
Yes, thank you, and I echo my congratulations. Steve, I was wondering if we could kind of shift the conversation away from kind of inventory and distribution, et cetera, and kind of characterize the demand environment, from a qualitative perspective, what you're seeing in kind of industrial IoT, automotive, and ADAS, how that's maybe different from last year trends and kind of going forward.
I think, demand environment is really as normal as it can be described. I mean, there are always outliers, but demand environment is normal. I think last year, some of the lead times ran out and the environment was more heated after many, many years of low single-digit growth in the industry. Last year industry growth was very positive. This year, the growth is less than last year, but growth is still quite healthy, and the business environment is kind of more normal this year than it was last year. I don't think anybody argues the industry can grow 13%, 14% per year. That's kind of where it grew last year. This year seems to be more normal.
Okay, got it. More normalized growth rate versus last year. Then Eric, in terms of the CapEx, is this kind of the Well, the CapEx is going to change with Microsemi, but I'm wondering if you could kind of give us some insight on how we should think about CapEx in fiscal year 2019, but also on more on a longer-term basis.
For fiscal 2019, we just guided today for CapEx to be between $200 million-$250 million for the year. That includes about $70 million of building projects. There can always be some building projects going on, but we've got four different projects around the world that set us up nicely for efficient growth going forward and we reduce lease costs and things like that. I'd call that one kind of out of the ordinary. If you take building projects out of the last fiscal year, fiscal 2018, as well as fiscal 2019 at $170 million-$175 million range for CapEx, I think that's normal in a growth environment. If for any reason we saw growth decline, our maintenance CapEx is significantly lower than that, and we've seen that, how that can come down dramatically.
We're investing for growth, we're investing to bring manufacturing activities in-house, which enhance our gross margin going forward and give us more control over the overall supply chain. We'll continue to make those investments.
Okay, got it. Just one question on the de-leveraging rapidly. Can you talk about any specific tranches that you're going to start taking out? What the impact will be on the interest expense in the near term and the medium term? Thanks.
I'll take that question, and we're not ready to give specifics yet, but Steve did say in his prepared remarks that really all of our cash flow, outside of what we have for investing in the business and CapEx and dividend, will be used to rapidly de-lever. If you look at the combination of Microchip and Microsemi, these are two very high-quality, high operating margin, high cash flow companies, and those models combined will improve from where they are on day one. Really all that cash generation over the first couple of years is absolutely going to be going to pay down debt and drive us to that 2.5 times leverage target that Steve mentioned in his prepared remarks. Don't have specifics by quarter or by year, but I think modeling can come up with a pretty good estimate.
You can see what we did with the Atmel de-levering as well.
Good point.
Yeah. Excellent. Thank you.
Yeah, I mean, we're going to pay the highest interest first, kind of no-brainer, and with some regards to looking at what's a fixed debt and what's a variable debt, and basically combination of paying down term loan and the line of credit, some combination of that.
Our next question comes from Gil Luria with D.A. Davidson. Please go ahead.
Good morning, congratulations. On the Microsemi acquisition, I don't recall what you thought the earnings accretion might be year one and three. As you did your due diligence, can you comment on any positive or negative surprises? Thank you.
Well, it's a very general question. Since we announced the transaction, we haven't seen any positive or negative surprises. During the diligence, prior to announcement of the transaction, we didn't know as much about the company before, so we didn't really have a baseline against we could see that this was a positive or negative. There always are, as we went through various business units and corporate profile, there were things we liked and the things we did not like. I think it would be probably a longer discussion to go into it, nor do I remember offhand. I think the next step is when we close the transaction and then spend 90 days with the company. That's when we will see probably, what we found as a positive or negative surprise. Probably ask that question in another couple of earnings call later.
Right. Maybe I can just add to that to refresh people's memory of what we said on March 1st, and things haven't changed from that standpoint. We were assuming a June 2018 close, which is still our expectation. We had indicated that Microsemi would add $0.75 of non-GAAP EPS accretion on an annualized run rate basis in the first year after close. In the third year after close, that we would achieve $300 million in synergy from cost savings and revenue growth, and Microsemi would contribute $1.75 of non-GAAP EPS.
I thank you very much. Congratulations.
Thank you.
Our next question is from Kevin Cassidy with Stifel. Please go ahead.
Thanks. Within your microcontroller business, what was the fastest growing? The 8-bit, 16-bit, or 32-bit? Is it units driving the growth or $?
Steve, I can take that. We don't break out growth rates for revenue by segment of the microcontrollers. As you can follow from the prepared remarks, all of them have been setting new records. There's no one of them that is providing the growth that is offsetting anything in the other ones. We're very happy with all three of them, and I think outside of that, there's nothing more to say.
Okay. I know you don't break it out by end markets, can you say what area of the world that you're seeing the best growth from?
Our growth is reflected in how revenue for the company is broken out by the year, by the regions of the world. We have just under 20% in the Americas, just over 20% in Europe, and the balance is all in Asia. Now, Asian revenue reflects not only local consumption and local demand creation, but also represents business that is manufactured there for U.S. or other European companies, which then go back to the originating country. That growth is very similar to the growth rates by end market, and the microcontrollers being such a dominant portion of Microchip at 65% revenue, are going to be in the same range as what Microchip is growing in any of those regions of the world.
Okay, thank you.
As a reminder, it is star one if you would like to ask a question. Our next question comes from Charlie Anderson with Credit Suisse. Please go ahead.
Hi, this is Charlie Anderson on behalf of John Pitzer. Thanks for letting me ask a question today. I was hoping to dive a little bit deeper into the March quarter revenue. Specifically, you narrowed rev guidance on March 1 with a midpoint that was mostly unchanged. Could you just talk a little bit more about what specific buckets of revenue saw upside over the remaining month of the quarter? Thank you.
I don't think we have that data by buckets. By buckets, I don't know whether you mean geographically buckets, or you mean by end markets, or you mean by product line?
Just generically end markets or product lines or whatever you could provide would be helpful. Thank you.
End markets, we don't know, because on a quarterly basis, we cannot break our business by the end markets across 115,000 customers where 53% of the business is through distribution. We only provide the data once in a while after we do some painstaking amount of work. We don't really have the data by end market. By product line, Eric, any nuggets of where the extra growth came from?
Honestly, I think from March 1st to the close, we saw strength across really all of the product lines. They all performed well. You will definitely see that in the quarter, the analog business performed better than the microcontroller business, but that was the opposite the quarter before that. Europe was very strong. That's typically what we see in the March quarter, and it closed out strong, I really don't think that we can peg it down like that. Just good overall growth across the various product lines.
We cleared some delinquencies that helped to, in the month of March, help the growth that we had been expecting versus what we actually saw.
Thank you.
Our next question comes from Christopher Rolland with Susquehanna. Please go ahead.
Thanks, guys, and nice execution on the quarter. I like the sell-through, that you guys are going to report. I wish more people would do that as well. Perhaps you guys can describe how big that difference is between sell-through and sell-in that we've seen in the past. Then Steve, I almost get the sense that you kind of philosophically are against sell-in. Some people think it creates bad behaviors. You're not going to incentivize your sales force on sell-in. I was wondering if you could talk about philosophically how you view that. Thanks.
You're absolutely correct. We are philosophically against sell-in because in sell-in, your relationship with distributors is built on commercial, making the deals where the buyers are distribution to stuff the channel, essentially, "Hey, buy more of my parts, buy more of my parts." In a sell-through incentivization of the sales force, your effort is in driving design wins to revenue so that the parts are going out from distributor shelf to the end customer. That's the main difference. Company after company that we've been involved in, the companies we have bought, Atmel and Micrel and others, they all had sell-in revenue recognition and now we know their history.
We have the record, we have their books and the amount of managing the quarter that goes on at the end of the quarter by giving distribution deals, from pricing concessions to payment terms to buddy-buddy distribution, please take another $10 million from me. All that happens is really bad behavior, and it doesn't represent demand. During the last few years, as FASB was looking at defining revenue recognition, we fought that. I think we wrote a paper on it a long time ago, FASB went down the decision where the revenue recognition for GAAP has to be sell-in. We lost that battle, therefore, we have to announce GAAP based on sell-in. We're not going to throw our religion away. We're going to manage the business based on sell-through. We're going to create demand. Our motto is drive design wins to revenue.
We're going to incentivize our people. All bonus programs will be based on sell-through. We're going to measure distribution based on sell-through, but we'll go through a SEC-required GAAP exercise to report a sell-in.
Great. Thanks for that color and thanks for offering sell-through. Going forward, for me, OpEx was a tiny bit higher as a percentage of revenue. Perhaps just if you guys could talk about where those investments are going. Thanks.
I don't think the change is meaningful in terms of any conscious investments we made anywhere. I think it's just a large juggernaut and there are lots of moving parts, exchange rates too. In the first quarter, you have some of the Social Security payments come back in for some of the people who are maxed out in the later quarters, and you could have slightly lower turnover, higher turnover, and not being able to replace the people. It's just a whole bunch of moving parts. There was really nothing. No conscious decisions were made to invest more or less.
Great. Thanks, guys.
Thank you for adding, [inaudible].
for the end of the quarter.
Yeah, I'm just going to add one thing onto that. We've been operating below what Microchip has said has been our operating expense model. To drive a 40% operating margin company, you have to make investments in R&D, in technical salespeople, and support functions and everything that goes into it. We have a lot of open requisitions in the company, and we're going to continue to make those investments to make sure our business just isn't strong today, but it's strong three, five, 10 years from now.
Great. Thanks, sir.
Our next question comes from Harlan Sur with J.P. Morgan. Please go ahead.
Good morning. Great execution on the fiscal 2018 performance. The analog business drove about half of the incremental upside in the March quarter, and it grew about 5% year-over-year. That's kind of a nice acceleration from the 1.5% growth in the prior quarter and a deceleration trend prior to that, and this is despite the reclassification headwinds. Is the year-over-year reacceleration a reflection of the increased attach rates you're achieving per program as you highlighted at Analyst Day, or you think it's just normal quarterly fluctuations?
Ganesh?
There's certainly some of that, which is a reflection of work we have done previously from an attach standpoint. We've been telling you for several quarters that the headwind is only because of the way we reclassify, that the underlying fundamentals of the analog business and what we are doing to create growth and attach and all those other things remain intact. Quarter to quarter, you're going to see fluctuations on it, I think the longer-term trend you should expect is that analog will have nice growth associated with what we can do with selling it as a part of our total system solutions.
Great. Thanks for the insights there. Aerospace and Defense is only about 2% of core Microchip business, pre-Microsemi. That percentage mix increases about 5.5x with Microsemi. I've heard that A&D is more sticky than your industrial products. I hear margins in A&D are better than industrial. First of all, would you agree with that, and does Microchip have a family of high-rel radiation-hardened MCUs, or is that something you guys hope to achieve with the Microsemi team? Thanks.
Ganesh?
Clearly the portion of our business that'll be Aerospace, Defense and Space will grow up with Microsemi. It is very sticky business. It is high-margin business. In that sense, it joins the family of industrial and automotive and other product lines we have that have similar characteristics. Some of the work technically that we have to do also take advantage of what we have to do for industrial and automotive. Specifically to the rad-hard product line, yes, we do have rad-hard microcontrollers. Some of that work obviously started from Atmel and what they had been doing prior to the acquisition. Microchip had been building more products that were ready for defense business, but the rad-hard portion came really from the Atmel heritage, and it will grow significantly with Microsemi's portfolio, which is quite rich in other areas as well of defense and aerospace.
Great. Thank you.
We have no additional questions at this time. I would like to turn the call back to Mr. Steve Sanghi for any additional or closing remarks.
We want to thank all the investors for joining this call and for being investors in Microchip. All the best from us, and we'll see you during the quarter, maybe at some of the conferences. Thank you.
Ladies and gentlemen, this concludes today's call. We thank you for your participation. You may now disconnect.
