Thank you, Leanne. Welcome everyone and thank you for joining us today. Diodes achieved a number of key milestones in the second quarter, reaching record level across market for our financial metrics, driven by continuous revenue growth, market share gain, and further traction on [Indiscernible] quarter.
Our extraordinary strong performance reflect record sales in both our automotive and industrial end markets, which contributed to a new record revenue level achieved across all regions.
Our automotive revenue was up 50% year-over-year and our industrial revenue at 27% of total revenue was the first time that industrial was our largest representative end market. Additionally, through revenue growth, we continue to decrease in operating expense as a percent of the revenue, also, contributing to our achievement of record EBITDA and record non-GAAP earnings per share in the quarter.
In fact, EBITDA increased over 40% and the non-GAAP net income over 60% as compared to the prior year period on revenue growth of 15%. This further demonstrates the significant leverage in our operating model. As a result, we generated strong cash flow that enabled us to further pay down our long-term debt.
Also, highlighting those solid results is our expectation for continued growth in the third quarter, where we expect to, again, set new records across our business. Our strong results and the growth this year has positioned us with the potential to achieve our most profitable year in the company's history.
With that, let me now turn the call over to Rick to discuss our second quarter financial results and our third quarter guidance in more detail.
Thanks Dr. Lu and good afternoon everyone. As part of my financial review today, I will focus my comments on the sequential change for each of the line items and would refer you to our press release for a more detailed review of our results as well as the year-over-year comparisons.
Revenue for the second quarter 2018 was a record $304.1 million, a 10.8% increase from the $274.5 million in the first quarter of 2018. GAAP gross profit for the second quarter 2018 was also a record at $107.3 million or 35.3% of revenue, representing an 8.8% increase on a dollar basis from the $98.6 million or 35.9% of revenue in the first quarter 2018.
Pricing approved in the second quarter versus first quarter, which offset some lower margin inventory sales due to our inventory reduction efforts. GAAP operating expenses for the second quarter 2018 were $69.4 million or 22.8% of revenue and $64.2 million or 21.1% of revenues on a non-GAAP basis, which excludes $4.7 million amortization of acquisition-related intangible asset expenses and approximately $500,000 of KFAB restructuring costs. This compares with GAAP operating expenses in the first quarter 2018 of $71.7 million or 26.1% of revenue and $64.7 million or 23.6% of revenue on a non-GAAP basis.
First quarter included $2.6 million of offshore retirement expenses, which were not repeated in the second quarter. Total other expenses amounted to approximately $1.4 million for the quarter, including $2.5 million of interest expense. Income before taxes and non-controlling interest in the second quarter of 2018 amounted to $36.4 million compared to $26.3 million in the first quarter 2018.
Turning to income taxes. Our effective income tax rate for the second quarter 2018 was approximately 29.5%. GAAP net income for the second quarter 2018 was a record $25.1 million or $0.49 per diluted share compared to GAAP net income of $18.5 million or $0.37 per diluted share in the first quarter 2018. The share count used to compute GAAP diluted EPS for the second quarter 2018 was 50.8 million shares.
Second quarter 2018 non-GAAP adjusted net income was $29.3 million or $0.58 per diluted share, both of which were records. The adjusted net income excluded net of tax $3.8 million of non-cash acquisition-related intangible asset amortization costs and $400,000 of restructuring expenses. This compares to non-GAAP adjusted net income of $24.2 million or $0.48 per diluted share in the first quarter of 2018. We have included in our earnings release a reconciliation of GAAP net income to non-GAAP adjusted net income, which provides additional details.
EBITDA, which represents earnings before net interest expense, income tax, depreciation and amortization, was a record $64.5 million or 21.2% of revenue in the second quarter 2018 compared with $54.2 million or 19.7% of revenue in the first quarter 2018.
Cash flow generated from operations was $34.4 million for the second quarter 2018. Free cash flow was $13.1 million for the second quarter, which included $21.4 million of capital expenditures. Net cash flow was a negative $30.1 million, including the pay-down of approximately $36.1 million of long-term debt.
Turning to the balance sheet. At the end of the second quarter, cash and cash equivalents plus short-term investments totaled approximately $160 million. Working capital was $380.8 million and long-term debt, including the current portion, was $185.8 million.
At the end of the second quarter, inventory decreased by approximately $14 million from the first quarter 2018 to approximately to $223 million. The decrease in inventory reflects an $18.7 million decrease in finished goods, a $900,000 increase in work in process and a $4.1 million increase in raw materials. The decrease in finished goods inventory reflects our focus on reducing finished goods inventory after four consecutive quarters of finished goods increases. Finished goods inventory days were 38 in the quarter compared to 44 in the first quarter. Total inventory days were 106 in the quarter compared to 116 days in the first quarter of 2018.
Capital expenditures on a cash basis for the second quarter were $21.4 million or 7% of revenue. This CapEx was to put capacity in place or the expected strong revenue growth in the second half of 2018. We expect CapEx for the full year 2018 to return to our target model of 5% to 9% of revenue.
Now, turning to our outlook. After growing 10.8% sequentially in the second quarter, for the third quarter 2018, we expect continued strong growth with revenue increasing to a range of $313 million to $329 million or up 2.9% to 8.2% sequentially.
At the midpoint, this represents a 12.5% growth versus third quarter 2017. We expect GAAP gross margin to be 35.8% plus or minus 1%. Non-GAAP operating expenses, which are GAAP operating expenses adjusted for amortization of acquisition-related intangible assets are expected to be approximately 21% of revenue, plus or minus 1%.
We expect interest expense to be approximately $2.5 million. Our income tax rate is expected to be 29% plus or minus 3% and shares used to calculate diluted EPS for the third quarter are anticipated to be approximately 51.4 million.
Please note, that purchase accounting adjustments of $4 million after-tax for Pericom and previous acquisitions are not included in these non-GAAP estimates.
With that said, I will now turn the call over to Emily Yang.
Thank you, Rick and good afternoon. As we previously highlighted, second quarter revenue was up 10.8% sequentially and up 15.1% year-over-year Q2 distributed POS increased by 15% and POP was up by 14%. All regions reached new record revenue levels of record POS results. China inventory decreased 1.3% sequentially.
During the quarter, we said revenue records on 10 product categories, including AC/DC, battery management, ASIC Interface, LED, MOSFET, standard linear, and switch. We also achieved continued strong momentum in CMOS LDO, Aris [ph], power protection, sensor, and signal integrity, driven by a recent design wins on new products.
Our consistently strong revenue growth is evidenced of our success over the past several quarters with new product introductions, designing momentum, and expanding contract of customers. We expect to continue making additional progress in the second half of 2018.
Looking at global sales in the second quarter, Asia represented 78% of the revenue, Europe 13%, and North America 9%. In terms of our ends market, industrial represent 27% of revenue, consumer 25%, communication 23%, computing 16%, and automotive 9% of the revenue. This was the first time that industrial was our largest representative end market as a result of a continued expansion of the growing market.
Starting with industrial market, Diodes continue to see strong demand for LDOs and LED driver in the souvenir [ph] lighting as well as increasing demand for audio products in the smoke detector, alarm-related applications with audio alarming features. We also continue to demonstrate industrial pace using normal density, trench mark technology, and CMOS application, such as brushless DC motor and LED lighting.
Also, during the quarter, we introduced new product in our high performance high impact launch products that are specifically designed for communication of brushless motor, slow meters, linear and coders, and position sensors in the industrial application.
Turning to our automotive market, which remains a key focus area for Diodes and was up 50% year-over-year. Our design win momentum continues in the three application areas I discussed in detail last quarter. Connected driving, which consists of ADAS, Telematics, and Infotainment system, comfort style and safety, including lighting and brushless DC motor control, and Powertrain covers conventional hybrid electric vehicles.
Contributing to our growth was the successful ramping of the past design wins for power transistors, for driving LEDs in the car lightings. There is also increasing demand for USB Type C product in the automotive applications like infotainment, connected driving in the newer models allow a strong interest in packaged switches and telemetric application.
Additionally, with regular increase of electronics in today's highly connected cars, robot ESP protection is also important. We expect to see strong growth for our protection product in automotive applications in the coming quarters.
We're also seeing new design wins for sensor products with a focus on window, by roof, door, tailgate, seat, seatbelt, gear stick, and mortar applications. Additionally, the market growth for automotive MOSFET continue to be strong, especially in China, where we see significant demand for automotive semiconductors.
Significant multi design wins are being achieved in brushless DC motor, water pump, power windows, electric horn, infotainment, battery management system, and ADAS. In the consumer market, we continue to see growth in charging applications, such as quick charger, direct charger, and wireless power charging as well as in IoT applications, such as smart devices, smart audio, and wireless speakers.
In addition, we see growing demand for USB Type C interface in mobile and IoT devices. As such, the market is responding to customers' demand regarding multiport USB chargers and we expect strong demand for our USB TV decoder devices that have passed USB/PD device certification. Our large selection of protection devices are also gaining momentum in the panel market; mobile, TV, monitor, and notebook panels as well as earphones, wearable, portable, and smart speakers applications.
Turning next to communication market. We continue to see a new design wins in mobile market for charging, power management, and discrete products. We are seeing strong demand for high-voltage charging using USB 2 interface in mobile and smartphone setting. We have secured an increasing number of design wins for our MiFID switch solution, driven by increasing demand for camera module in mobile phones.
Specifically, in smartphones, power density remains a key concern for both manufacturers and consumer. Diodes has been actively addressing this area of the market with this comprehensive smart footprint DFM and CFP MOSFET portfolio. In addition, Diodes continues to expand our portfolio of battery protection MOSFET with our most recent release in Q2.
Lastly, in the computing market, we have continued to see strong growth momentum for the data centers, server, storage, AI, and deep learning, along with PCs and notebooks. We have launched several new products, including PCIe Packet Switch, PCIe Clock Generators, Buffers, and ReDrivers that are suitable for this applications.
We are also seeing increasing interest in our protection devices in the computing market as well since USB Type C is a major growth engine for this device. Our existing solution for to protect all things on type C connector, it's been well received by customers. We have new design wins for our USB Type C [Indiscernible], the DC switches in notebook docking applications beyond our current success in PC [Indiscernible].
In summary, we are very pleased with our performance in the quarter, reaching record levels across a number of financial metrics as well as end markets, targets, geographies and product categories. This achievement are underpinned by our market share gain, customer contact expansion initiatives, as well as continued traction with Pericom products. With continued growth expected in the current third quarter, we anticipate once again setting new records across our business.
With that, we now open the floor to questions. Operator?
Thank you. [Operator Instructions]
And our first question comes from the line of Tristan Gerra from Baird. Your line is now open.
Hi, good afternoon. Looks like in demand [ph] trends remain very strong, but also that the industry is seeing some pressure in terms of manufacturing costs. Could you quantify perhaps the gross margin impact embedded in your Q3 guidance from those higher manufacturing costs? And plans you have to mitigate those higher costs going forward?
Hang on just a second, Tristan.
Tristan, number one, if you see the guidance for our third quarter, our gross margin actually from 35.3 increased to 35.8., okay? So, even some of our material costs went up, but we still due to the cost reduction effort, due to the mix improvement efforts, we still able to increase our gross margin in a flat 15 basis points.
Okay. Okay. I appreciate the feedback. And perhaps we can take it offline. Also you've mentioned inventory reduction that was expected, is that something pretty much completed or do you expect to further reduce channel inventory in Q3?
So, Tristan, the inventory reduction -- let me comment about Diodes' inventory reduction and then Emily can talk about the distributor inventory. So, from a Diodes' perspective, we had a plan to reduce the inventory. We had noted that it had gone up over the last year. Every quarter, it was just up a little bit and we had a plan internally to reduce that inventory and as you can see that we reduced it that $19 million from our finished goods perspective. And in the third quarter, I think we're going to have an additional inventory reduction, but it's not going to be a significant as it was in the second quarter.
And Tristan for the channel inventory, as you noticed is that we had a record POS record in Q2 and our inventory actually went down in Q2. So, I think the key focus is really keeping a healthy inventory profile in the channel to support and sustain our growth. So, we monitor this very closely. I think the key is really healthy inventory to support it.
Typically, our [Indiscernible] would like to have more inventory when the revenue is going up in the future, but we actually -- you can see the effort we put in, in the second quarter, but in the second quarter, even they thinking third quarter revenue would be up, their inventory actually went down and that's because POS is very strong, but we are not pushing the POP. We tried to reduce the inventory and keep it healthy such that we don't need to worry about double ordering or worry about inventory too much in the [Indiscernible] side.
So, our goal is to inventory stays in the channel, will not increase.
Okay, that's very useful. And just last one for me. In the context of the tariffs, how much of Diodes' business is silicon shipped to the U.S. not final products sold to U.S. OEMs, but silicon sold to [Indiscernible] and EMS and therefore, subject to potential tariffs, I'm just trying to get a sense of your potential exposure there.
Yes, so let me answer that. So, Diodes, the products that we import into the United States from China, all of those products are going to be ultimately affected by the tariffs. Right now, there are two tariff lists. The first tariff list was a smaller list and it was effective on July 6th. And we think the impact of that was about $1.1 million per quarter of tariff cost.
Now, there's another list that hasn't been actually put in place yet, but the list is out there, and we've looked at that and we're uncertain about the implementation date, but based on the estimate, we think that that impact is going to be about $2.5 million a quarter. So, if you take the total of those two, it's about $3.6 million per quarter, but we plan to pass these tariff charges on to our customers.
Okay, great. Very useful. Thanks so much.
Okay.
Thank you. And our next question comes from Gary Mobley from Benchmark. Your line is now open.
Hello everyone. Thanks for taking my question. In the quarter -- in the second quarter or even it embedded in your outlook for the third quarter, were there any supply chain constraints that restricted your revenue. And if so, can you speak about them and what revenue could have been if weren’t capacity-constraint?
Okay. We really -- and in a certain degree, expect wafer do have some shortage, no order for the nine has a shortage. The shortage is most coming from the MOSFET. And that is really start with shortage and cost to certain degree of the MOSFET wafer shortage and it affects us, but a lot of our customer is hand to mouth type of situation.
But I could not -- or I cannot give you the forecast if no shortage profit revenues because we just driving our best we can to support the customer demand, but fortunately, we are able to keep the nine do not have a situation, but that's really limited to certain product lines.
Okay. Typically, in the fourth quarter, you see sequential revenue decline somewhere in the neighborhood mid-single-digit percent sequentially. Would you -- based on your visibility sitting here today, would you call the fourth quarter is typical or atypical as a matter of seasonality?
Well, I don't know very clear yet, but so far, I'm hoping, it's not typical, okay. It's better than typical, but I really don't know, okay. Right now I'm focused on the third quarter and we do see a very strong third quarter above the typically second quarter to third quarter is about 5% or -- between 0% to 5% growth and we are able to guide above 5% growth. So, we see better than silicon cycles.
Now, in the fourth quarter, right now, not very clear, but we watch out, okay, and hoping still better silicon is 5% in that and I hope it's better than that, but I don't know yet.
Okay, all right. Very good. I'll let others ask questions. Thanks everyone.
Thank you. And our next question comes from the line of Shawn Harrison of Longbow Research. Your line is now open.
Hi everybody and congrats on the results.
Thank you.
The first question has to do with the gross margin performance for the June quarter. If there is a way to delineate maybe how much of the negative impact the inventory drawdown presented on gross margin as well as the incremental CapEx investment from prior quarters? And how much of that may be rolls off into the September quarter?
I probably cannot give you the exact number, but if you look at, we've finished good $17 million and if you think in the past $17 million, I assume this is not the high [Indiscernible] average, if you're talking about let's say, 10% that means, you've gone to reduce $1.7 million of it, the TP to the average. So, you can see it's a big numbers.
And even in the third quarter, we still intend to reduce more. Basically what I wanted to do is by the end of third quarter, the inventory level [Indiscernible] last year third quarter, end of third quarter levels.
With the revenue, if you compare this year third quarter based on our -- versus last year third quarter, the revenue going to grow quite a bit, but we're hoping we try to drive in this -- the -- our own inventory is best, the same level that means as a percentage it would be much less. That's the goal.
Okay, that's helpful Dr. Lu. And as the follow-up, I was hoping you could speak on the ramping of the 8-inch capacity as well as the transferring of equipment from the KFAB closer into existing sites and where you're at on progresses of both?
Okay. Let's talk about inventory comment. We continue to ramping up, okay, I said last time, we're talking about in 1Q, we only ramp up 800 something wafers less than 1,000 wafers and then, in the 2Q, I think, we are now somewhere -- end of 2Q, we are somewhere around 5,000 to 6,000 wafer per month.
We ramped it up to the end of the second quarter to about 5,000, 6,000 wafer per month. Then we go to the third quarter, we are continuing ramping up, I don't know what, but as far as not yet [Indiscernible] but we'll continue ramping up.
By the end of fourth quarter, I'm hoping we are hoping running somewhere around 9,000 wafers per month. So, we continue to ramp it up.
So, from a 6-inch perspective, we've moved all of those KFAB equipment to SFAB1. It's in the process of being qualified and ramping up, but KFAB has been closed, all of the equipment, everything has been moved. So, it's basically finished.
Okay. Then last, if I may. I know last quarter, there are some -- I think it was -- the term may have been equity investments in the Chengdu that could limit your ability to pay down debt in the back half of the year. But given due to the increased profitability, do you think you'll be in a net cash position exiting 2018 now?
We will make that investment in Chengdu, probably in the next four, five months. We hope to be able to fund that internally, which would preclude us probably from paying down the debt as much as we would like. But we're still in the process. You can see the results are good and operating cash flow is $35 million. So, in fact, it can continue then, we should be on a pretty good position to, at least, continue to pay down some debt.
Okay, perfect. Thank you very much.
Thank you. [Operator Instructions]
And our next question comes from the line of Edgar Roesch from Sidoti & Company. Your line is now open.
Thanks and congratulations.
Thank you.
Thank you.
Thank you.
So, to lead off, earlier in the year, industrial saw a lot of strength from Europe, I think, that led the gains. Did you see that broaden out or is that really still a center of activity for your business?
This is Emily. We're actually seeing across the Board strength in the industrial segment, not only in Europe, but also in North America, as well as in Asia. So, this is across the Board. So, that's how we can achieve our 27% overall end market percentage rate.
Okay, got it. And do you have any exposure to home appliances and can you remind me, which category in which that would fall?
Yes, we do. I think home appliances would be under the consumer segment that we include that over there.
Industrial like hand tool.
Right. So, home appliances, that would be in the consumer, but we also have a lot of industrial applications, [Indiscernible] but that would be under the industrial.
Yes.
Okay. Thanks. And then I think you recently or earlier this year, you launched some higher-voltage products, ICBTs and some other products. And I was wondering do you feel like you have on the power management side a pretty good range of voltages covered? Or is that an area where you will have some new product activity to augment your portfolio?
I think we have overall good coverage from the product. When you really look at across product line, there's quite a number of products which are in the higher-voltage area, but there's still room for us to expand. And one of the things that we're working aggressively is that we continue to develop new products targeting higher-voltage areas.
Well, as you can see we just started that is in the past, it's not our focus area, and we [Indiscernible] our MOSFET. We think we are on the position now to get into ICBT areas. So, we start with the buy and resale for the ICBT parts, but eventually, all gain through the super junction to ICBT, but right now that's very beginning of our actions.
Okay, that's helpful. All right, I think that does it for me. Thanks.
Thank you.
Thank you.
Thank you. And that concludes our question-and-answer session for today. I'd like to turn the call back over to Dr. Lu for closing remarks.
Thank you for your participation on today's call. We're looking forward to providing an update on our business next quarter. Operator, you may now disconnect.
Ladies and gentlemen, thank you for your participation in today's conference. This concludes the program and you may now disconnect. Everyone, have a great day.
