Thank you, Garo. Good afternoon, everyone, and thank you for joining us on today's conference call. We delivered a solid Q3 performance with strong execution from the team as supply chain headwinds continue to offset a very strong demand environment. Revenue in the quarter was $564.4 million, which was within our guidance range and grew 18% from a year ago and was essentially flat sequentially. Operationally, we continue to perform at a very high level, which contributed to record non-GAAP operating margins of 10.5% in the quarter, resulting in non-GAAP net income of $1.50 per share. Looking at the quarter in a little more detail, demand across all our product categories remains robust, with supply constraints remaining our biggest obstacle to higher growth.
During this period of component shortages, our team has done a terrific job managing these constraints to better serve our customers. One way we do this is to help our customers source and qualify alternative parts and materials for products we manufacture for them. Sometimes these substitutions are very straightforward, and at other times, more complex products can require re-qualification and validation, not just by our customers, but by their end customers as well. During the Q3 , certain customer programs were delayed by these component re-qualification efforts, adding an estimated $15 million supply chain related headwind to the $30 -35 million supply chain impact we had previously estimated. The good news is that these alternative components have since been fully qualified, and we have already resumed shipment of the associated products, meaning that the revenue has essentially shifted from the Q3 to the fourth.
Now let me provide some additional color on the Q3 . By end market, we had another strong quarter for Optical Communications. Telecom revenue grew both sequentially and year-over-year, and Datacom revenue grew from a year ago, but declined sequentially as this was the area most impacted by the component re-qualifications I just discussed. Non-Optical Communications revenue grew both sequentially and year-over-year to the highest level in our history, driven primarily by strong Automotive revenue, which was up more than 10% sequentially. While we have no direct business in Russia or Ukraine, our Automotive business saw a small impact in the quarter from customers with other suppliers in the region. Turning to capacity expansion, construction of Building 9, our new 1 million sq ft building at our Chonburi campus, is nearly complete.
This building increases our total footprint by approximately 50% to more than 3 million sq ft, which will provide us with ample capacity to meet demand from new and existing customers for some time. In fact, we're excited that certain existing customers experiencing rapid growth are already in discussions with us to expand into the new building. More on this during our Q4 earnings call. As we look at the Q4 more broadly, the strong momentum across all of our business is continuing. Our team continues to do an excellent job managing component supply issues, but these supply chain constraints have not shown any signs of improvement, and if anything, are increasing.
As Csaba will detail in a moment, our revenue guidance for the Q4 would have been $40 -45 million higher if not for these headwinds, which have grown substantially since the beginning of the year. That said, we expect to continue to benefit from our enviable track record of execution that drives industry-leading margins. In summary, I'm very proud of our team's strong execution, both in managing supply constraints as well as delivering industry-leading margins. With demand trends that remain very strong across the board, we are confident that we can deliver top and bottom line growth in the Q4 , including record profitability. Now I'd like to turn the call over to Csaba for additional financial details on our Q3 and our guidance for the Q4 of fiscal 2022. Csaba.
Thank you, Seamus, and good afternoon, everyone. Demand trends in the markets we serve continue to be very healthy, as reflected in our 18% growth from a year ago. While demand continues to increase, supply-related headwinds also grew in the Q3 , resulting in a slight sequential decrease in revenue to $564.4 million, which was within our guidance range. Another quarter of strong execution produced non-GAAP earnings per share of $1.50, which was consistent with the prior quarter. By end market, Optical Communications revenue was $440 million, down 2% from last quarter, but up 22% from a year ago. Within optical, Telecom revenue of $358.3 million increased 2% sequentially. Datacom revenue declined 17% to $81.7 million, due primarily to the requalification delays that Seamus discussed.
By technology, Silicon Photonics revenue was $144.9 million, an 8% decrease sequentially, reflecting the Datacom revenue decline. At 26% of total revenue, our Silicon Photonics mix was the second highest in our history. Revenue from products rated at speeds of 400G or more was up modestly from Q2, reaching a new record of $188.4 million. Revenue from 100G products dipped 11% sequentially to $124.6 million. Non-Optical Communications revenue was up 7% sequentially to $124.4 million and represented 22% of total revenue. Within Non-Optical Communications, Automotive revenue was $53.3 million, up 13% from last quarter, and Industrial Laser revenue was $39 million, which grew 9% sequentially.
Other Non-Optical Communications revenue moderated slightly to $32.1 million. As I discussed the details of our P&L, expense and profitability metrics provided are on a non-GAAP basis, unless otherwise noted. A reconciliation of GAAP to non-GAAP measures is included in our earnings press release and investor presentation, which you can find in the investor relations section of our website. We executed very well in the quarter. Gross margin reached 12.7% and was further assisted by a slight foreign exchange tailwind. Operating expenses in the quarter were $12.6 million, or 2.2% of revenue. This resulted in record operating income of $59.2 million, or 10.5% of revenue.
Effective tax rate was 5.4% in the Q3 , and we continue to anticipate that our tax rate for the fiscal year will be approximately 3%. non-GAAP net income was $56.2 million, or $1.50 per diluted share, which is consistent with our record Q2 performance. On a GAAP basis, net income was $1.35 per diluted share. Turning to the balance sheet and cash flow statement. At the end of the Q3 , cash, restricted cash and investments were $516.1 million, down $5.1 million from the end of the Q2. Operating cash flow was strong, $50.4 million, with CapEx of $23.5 million. Free cash flow was $26.9 million in the quarter.
During the quarter, we increased our buyback activity and repurchased 239,000 shares at an average price of $102.04 for a total cash outlay of $24.4 million. As a result, $52.3 million remain in our share repurchase authorization. Now I will turn to our guidance for the Q4 of fiscal year 2022. As Seamus indicated, demand for our services remains very strong across our business. We anticipate revenue in the range of $570 -590 million in the Q4 . This guidance includes the impact of growing supply constraints, which we estimate to be $40 -45 million in the Q4 .
We are optimistic that our strong execution will extend into the Q4 , and we anticipate non-GAAP net income to be in the range of $1.52-1.59 per diluted share. In summary, we are very pleased with our strong execution and the positive demand trends we continue to see across our business. We are optimistic that despite increasing supply chain pressures, we will be able to deliver sequential growth in both revenue and profitability in the Q4 . Operator, we are now ready to open the call for questions.
If you'd like to ask a question at this time, please press the star then the number one key on your touch- tone telephone. To withdraw your question, press the pound key. Again, that is star then one to ask a question. Our first question comes from Alex Henderson with Needham.
Thanks. I wanted to go, you know, to the recalibration on the Datacom products. Re-quals often take quite a bit of time. Was the total impact of that in the March quarter or does that also cover into the April quarter, and so it's holding back the June quarter somewhat as well, so that the full qualification processes will probably impact positively, somewhat sequentially the June quarter but also positively impact the September quarter?
Yeah, Alex. Hi, this is Seamus. Yeah, the impact was in Q3. The full impact was in Q3. Unfortunately, the qualification took a little bit longer than we would have liked, and it came right at the end of the quarter, so we weren't able to catch up. It's behind us now, so the full impact was in Q3, and therefore the full benefit will be in Q4.
Okay, there's no additional supply constraints that are created by those re-qualifications that actually helps mitigate some of the supply constraints. Is that right?
Yeah, that's correct. There's no additional constraints due to that particular qualification. That's not to say there won't be others that will pop up from time to time and certainly other supply constraints, but that particular specific issue is done and behind us.
Okay. Clearly, the lockdowns in China are on top of everybody's mind, in terms of supply chains and pretty difficult for us to evaluate. Can you give us any kind of qualitative comments around the degree to which you might have things that are embedded in your products that are derived out of China that might be impacted like circuit boards and things of that sort? What portion of your supply chain is emanating out of China, and is it exposed to either of the two regions that are currently being talked about as being locked down most aggressively?
Yeah. I think. I mean, the proportion of our supply chain would be similar to other contract manufacturers. The lockdowns, they've certainly, you know, exacerbated the global supply chain issues, but the impact on us has not been very significant thus far. In Q3, the biggest supply headwind continued to be from just standard, fairly standard parts, as increase in demand puts more pressure on supply chains. Now, that was further stretched by the timing of the re-qualification issue that we talked about earlier. And again, while the re-qualification is complete, you know, we expect additional headwinds from increased demand will persist into Q4. And probably beyond that, actually. We've included an impact of $40 -45 million in our Q4 guidance due to supply chain headwinds.
We haven't been hugely impacted by China. I think again, towards the end of the quarter, we had to do a little bit of scrambling, I would say, while, you know, the lockdown was going on in Shenzhen, that it impacted more logistics than actual component supply. A lot of material comes through Shenzhen, you know, but we were able to scramble and recover from that. Thus far, we have not been significantly impacted by the lockdowns in China.
That's good to hear. One last question, then I'll cede the floor. Can you talk a little bit about the systems market? You know, how much have you benefited? What's going on relative to the systems that you know ramp from your existing customers? When you think about your outlook and the degree to which you're impacted by that $40 -45 million, how are you taking into account the 50%-100% of a full year product in the backlog at those companies? I assume that that's not reflected in your numbers in any way or in that $40 -45 million.
No, because I think what's maybe more interesting is the backlog that they have, yeah, it might be a full year's backlog, but unless that translates into a huge increase for us, it's not particularly relevant to us. We continue to pursue new system wins at existing customers and new customers, in situations where we're already making a lot of the content. That's where it makes more sense for us and where we can be most effective and most successful. Timing of the new wins, it's very hard to predict, as you know, Alex, and they're usually driven by some external catalysts or external factors. While we're, you know, optimistic that there will be more system wins in the future, we can't guess as to when that might be. The demand remains strong.
Overall, the demand remains strong, very strong, I would say. The only thing limiting our revenue and our growth right now is component supply.
On the systems side, it is apples to apples at this point. We're not seeing any extraordinary growth, as a result of new systems lines coming in as opposed to, you know, the customers that you have won, you have now fully up on what projects they had. Correct?
That's correct. They're the you know the two big ones that we've talked about in the past are essentially grandfathered in at this point. The growth that we've been seeing you know nice growth. If you look at our year-on-year growth, it's a very nice growth. It's without those systems in Q3, without additional growth from those systems in Q3.
I see. Thank you.
Thanks, Alex.
As a reminder, to ask a question, press star then one. Our next question comes from Samik Chatterjee with JP Morgan.
Hi, this is Angela Lai on for Samik Chatterjee. Thanks for taking my question. On the gross margin line, you've posted the highest gross margin that we've seen in years. We're wondering, is there a pricing tailwind on gross margins? How are you maintaining high gross margins despite all the current supply issues?
Hi, Angela, this is Csaba. Yes. We indeed benefited from ongoing cost reduction efforts mainly on our gross margin line, so there is no pricing or whatsoever. We typically pass on supply-related headwinds on our customers without marking them up. There is definitely no pricing-related tailwind coming through the gross margin line. We continue to improve our cost structure and improve the gross margin. In addition, in the last quarter, we saw a 20 basis point benefit from exchange rates. Most of our labor cost base is in Thailand, and we saw a depreciation in the last 6 to 9 months as we're executing our hedging strategy, we were able to drop an extra 20 basis point to the bottom line in last quarter.
Got it. You know, barring that, you'd be about 12.5%, and that's what you posted last quarter. I guess the new question becomes, you know, is it sustainable, this sort of 12.5% gross margin or even beyond that moving forward?
Obviously, we are not guiding gross margins, but we are working hard to continue our cost reduction efforts. Obviously, exchange rate is rather unpredictable. I would say the best way to think about it, we have been executing our strategy in terms of cost reduction and maintaining and staying in our target gross margin range. I think the best way to think about it is to really look forward on this cost reduction efforts. If we see any benefits from exchange rate, we will be communicating and articulating that.
Okay. Got it. Just quickly, before I cede the floor, in that $40 -45 million in supply headwinds, is any part of that in the sort of impacts from Russia, Ukraine or China or any of that macro? Is it possible to sort of give us a window into how big that impact might be or become?
Yeah. No, not on the supply side. We don't have any suppliers in either Ukraine or Russia. Some of our customers, particularly on the automotive side, were impacted because they source a lot of cables and cable harnesses out of Ukraine in particular. But we haven't been impacted directly. We don't have suppliers in either Ukraine or Russia.
Okay. Got it. Thank you.
Thank you. Thank you.
I'm showing no further questions in queue at this time. I'd like to turn the call back to Seamus Grady for closing remarks.
Thank you for joining our call today. We're optimistic that as we continue to navigate supply chain constraints impacting the industry, strong demand trends and excellent execution from our team will result in record top and bottom line results in the Q4 . We look forward to speaking with you again. Goodbye.
This concludes today's conference call. Thank you for participating. You may now disconnect.
