Operator

Good afternoon, and welcome to Marvell Technology's fiscal first quarter 2023 earnings conference call. [Operator instructions]. After today's presentation, there will be an opportunity to ask questions. Please note, this event is being recorded.

I would now like to turn the conference over to Mr. Ashish Saran, senior vice president of investor relations. Please go ahead.

Ashish Saran -- Vice President, Investor Relations

Thank you. And good afternoon, everyone. Welcome to Marvell's first quarter fiscal year 2023 earnings call. Joining me today are Matt Murphy, Marvell's president and CEO; and Jean Hu, our CFO.

Let me remind everyone that certain comments made today may include forward-looking statements, which are subject to significant risks and uncertainties that could cause our actual results to differ materially from management's current expectations. Please review the cautionary statements and risk factors contained in our earnings press release, which we filed with the SEC today and posted on our website as well as our most recent 10-K and 10-Q filings. We do not intend to update our forward-looking statements. During our call today, we will refer to certain non-GAAP financial measures.

A reconciliation between our GAAP and non-GAAP financial measures is available in the investor relations section of our website. With that, I'll turn the call over to Matt for his comments on our performance. Matt?

Matt Murphy -- President and Chief Executive Officer

Thanks, Ashish. And good afternoon, everyone. In the first quarter of fiscal 2023, the Marvell team drove another record level of revenue at $1.45 billion, exceeding the midpoint of guidance, growing 8% sequentially and 74% year over year. We saw continued strength in bookings in all our data infrastructure end markets.

Higher revenue achievement was primarily driven by our datacenter market with additional strength from carrier infrastructure and automotive results both of which were also above forecast. Due to supply chain-related impacts, results from our enterprise networking market were below our guidance. However, growth was still very strong with revenue growing a robust 64% year over year and 9% sequentially. The Marvell operations team did a great job in navigating a tight supply environment that was further compounded by COVID-related manufacturing challenges at our suppliers in certain geographies.

Our team's efforts were a key enabler of our first quarter revenue, exceeding the midpoint of our forecast. We continue to make progress in securing additional capacity with our strategic partners to enable sustained revenue growth. Let me now move on to discussing our five end markets, starting with datacenter. In our datacenter end market, revenue for the first quarter was $640.5 million.

Leading our guidance, having grown 12% sequentially and 131% year over year. Strong performance was broad-based with multiple product lines contributing to excellent results. Cloud continues to be a source of Marvell's strength in the datacenter. We are enabling our hyperscale customers to add new use cases, bringing the benefits of AI and machine learning to businesses, increased process automation and productivity and drive deeper relationships with their customers.

Let me now discuss a number of Marvell product cycles driving strong growth in cloud, starting with electro optics. We are seeing strong demand for our PAM solutions inside datacenters and ZR pluggables between data centers. Inside cloud datacenters, lead Tier 1 customers are currently driving volume deployment of our PAM-based 200-gig and 400-gig solutions. The rest of the market has plans for starting deployments later this year and next year.

As bandwidth requirements continue to grow, we expect the role of PAM-based electro optics to expand, replacing legacy solutions and as a result, to grow our opportunity. We believe that the next generation of more powerful server CPUs will accelerate the need for PAM technology. In addition to this expansion, we are also increasing our content per module with our next generation of higher-speed solutions that we are now starting to ship. Driven by the growth in AI deployments, our first quarter results benefited from a ramp in volume shipments of our 800-gig PAM solutions at two large customers.

The bandwidth expansion inside datacenters is also driving a significant increase in connectivity between datacenters, creating a growing opportunity for our 400 ZR pluggable optics. Team is achieving great success by driving the adoption of these solutions at multiple customers, and we are projecting strong revenue growth from these products. Moving on to compute. Our cloud optimized design win momentum continued in the first quarter, and we won a custom SmartNIC at a hyperscale customer.

We are seeing more adoption of VPU-based architectures inside data centers, a trend that we are ideally positioned to address with our OCTEON platform, which is now in its tenth generation. This design win is one more example of the growing demand for cloud-optimized silicon, which we see as the largest incremental growth opportunity for Marvell inside datacenters. We are confident that we are uniquely positioned to win these opportunities with our leading portfolio of compute, networking, security, storage and high-speed electro-optics IT delivered on our five-nanometer platform. Moving on to storage within the cloud.

In the first quarter, cloud demand for high-capacity storage continued to increase, driving solid growth for our nearline HDD controllers and preamplifiers. Our SSD controllers also contributed to strong year-over-year revenue growth. We are now reaping the benefits from our datacenter SSD business, which we built from the ground up starting in 2016. We increased investment in critical IP development, accelerated our process technology cadence, and quadrupled our firmware team.

Working closely with the leading cloud companies, we optimized our SSD controllers to address their quality of service and security requirements. We developed state-of-the-art error correction for the most advanced NAND flash technologies coupled them with our in-house low-power fives, and accelerated our PCIe roadmap. All the leading SSD devices today are shipping PCIe Gen 4 solutions, Marvell has already won Gen 5 data center sockets at three key NAND OEMs. Additionally, we started investing in PCIe Gen 6 in 2019.

This development, coupled with our five-nanometer technology platform has enabled us to win a key NAND OEM for their Gen 6 SSDs. Our datacenter storage business has been built on a long and sustained period of technology investment, deep system knowledge, extensive customer relationships, and very sticky custom firmware delivered on our advanced process technology platform. We expect our position to continue to strengthen based on our proven technology platform and multiple secured design wins in the next generation of datacenter SSDs. We anticipate that the next big evolution in cloud datacenters will be the adoption of CXL or Compute XpressLink, an industry standard for connecting processors, accelerators in memory, and we are planning to enable that trend.

Last week, we held a tech talk in which we explained the fundamentals of CXL technology in its role in bringing new levels of performance to next-generation cloud datacenters. If you're unable to attend, I would encourage you to watch the recording posted in the investor relations section of our website. We described how silicon components based on CXL will facilitate new cloud architectures by addressing the multiple memory scaling challenges in current data centers. Put simply, CXL will finally allow DRAM memory to escape the constraints of being tied down to a single compute device such as a CPU and become a shared and pulled resource, utilizing the well-established PCIe fabric as the interconnect.

Marvell is uniquely positioned to address the CXL opportunity, given our deep relationships with memory OEMs, our growing position within hyperscale customers and our advanced PCIe roadmap. We recently bolstered our efforts in this area with the acquisition of Tanzanite, a leading developer of advanced CXL technologies. Their complementary IP and world-class team adds more resources to Marvell, accelerating our CXL road map to address opportunities in closed design wins, which are right in front of us at multiple customers. We see opportunities for a host of new products, including CXL expanders, cooling devices, switches and accelerators.

In addition, we see the potential to embed CXL IP in a broad range of our datacenter products, including ASICs, custom compute engines, DPUs, electro optics, retimers, SmartNICs, and SSD controllers. We see a multibillion-dollar PAM expansion opportunity driven by CXL overtime, and I look forward to updating you on our progress. Moving on to our expectations for the second quarter of fiscal 2023 from our datacenter end market, we are projecting continued growth to layer on top of the strong first quarter results. We project our data center revenue in the second quarter to grow sequentially in the low-single digits on a percentage basis and year over year grew approximately 50%.

We expect revenue from cloud to grow significantly faster than the on-premise market, both sequentially and year over year in the second quarter. As we progress into the second half of this fiscal year and beyond, we are looking forward to additional incremental contributions from our cloud Ethernet switches and to ramping our large set of cloud optimized custom design wins. Marvell's unique ability to offer all the critical datacenter IP under one roof, designed to work seamlessly together in a custom solution is proving very attractive to customers. As a result, our engagements with hyperscalers have moved well beyond pure ASIC programs to include various combinations of Marvell IP delivered in solutions tailored to each cloud's unique requirements.

Turning to our carrier infrastructure end market. Revenue for the first quarter was $252 million, above our forecast, growing 5% sequentially and 50% year over year. We previously reported a substantial -- sequential step-up of over 30% in our 5G business in the fourth quarter of fiscal 2022. From this strong base, it was great to see both sequential and year-over-year revenue growth for carrier continue in the first quarter.

The growth in 5G deployment, combined with Marvell product ramps, at multiple base station customers continue to fuel strong growth in this end market. In wired, we are seeing strong demand for our 400-gig coherent electro-optics portfolio driven by rapid adoption in the metro and long-haul carrier markets. Coherent technology is critical to enabling high-speed data transmission across long distances to meet the ever-increasing demand for bandwidth from operators. Earlier this week, we announced that we have shipped over 100,000 400-gig coherent DSPs, positioning us as the leading merchant provider of these products.

We are also aggressively focused on developing and launching our next generation of coherent products. This is a very key piece from the Inphi acquisition as the same technology powers the 400 ZR DCI cloud market you heard about earlier. Looking ahead to the second quarter, we expect revenue from the overall carrier end market to grow in the high-single digits sequentially on a percentage basis, while year-over-year growth is expected to remain strong at approximately 40%. Moving on to our enterprise networking end market.

Revenue for the first quarter was $286.6 million, growing 9% sequentially and 64% year over year as demand remains strong in this end market. While this end market represents our highest delinquency relative to the size of the business, we remain strongly focused on improving our ability to supply more products to our enterprise networking customers to help them meet their growing demand. Our growth has been driven by share gains and our increase in content starting to materialize as our customers began shipping their new platforms to address enterprise network modernization. We have seen a large increase in the adoption of our multi-gigabit fives, which have a significantly higher selling price compared to our gigabit products.

We expect the penetration of multi-gigabit ports will continue to increase a tailwind to our business. Our strong growth in enterprise networking is primarily the result of our own unique product cycles. Looking beyond this quarter, we expect growth to continue leveraging our refresh switch and PHY portfolio and incremental revenue from the ramp of custom silicon and our OCTEON ARM-based DPUs displacing alternative architectures. The second quarter of fiscal 2023, we expect a continuation of strong demand for our products from the enterprise networking end market and further improvements in supply.

As a result, we are projecting revenue to be up sequentially in the mid-teens on a percentage basis and year-over-year growth of approximately 45%. Turning to our automotive and industrial end market. Revenue for the first quarter was $89.3 million, growing 12% sequentially and 94% year over year. All of the sequential growth came from our automotive business, which drove over 50% of the total revenue from this end market.

Although we are still unable to fully satisfy the growing demand for our Brightlane Auto Ethernet solutions, the results supported by incrementally better supply solutions exceeded our guidance. Our auto revenue growth is being driven primarily by our new product cycles. The adoption of Marvell Ethernet technology in cars is continuing to increase, as OEMs design in higher-speed solutions to address the increase in bandwidth, our dollar content per car is continuing to grow. We are also winning new customers and growing our content at existing customers.

We now have Ethernet design wins at eight of the 10 largest auto OEMs worldwide and 36 OEMs in total. Looking ahead to the second quarter of fiscal 2023 for the combined auto and industrial end market, we are projecting sequential revenue growth in the mid-single digits on a percentage basis, while year-over-year growth is expected to be over 60%. We expect strong growth to continue from our automotive business with revenue projected to more than double year over year. Moving on to our consumer end market.

Revenue for the first quarter was $178.5 million, growing 7% year over year. The growth in this end market is being driven by our SSD controllers, partially offset by declines in our PC HDD business. On a sequential basis, revenue declined by 4% in our consumer end market, below our forecast for a flattish outlook due to a reduction in demand from the PC HDD market. While we are not the bellwether of global PC demand as it represents a relatively small amount of our revenue, we did see a rapid change in tone from the PC market, and we expect the weakness to continue.

From our perspective, the shift from HDDs to SSDs in the notebook PC market is almost complete, and our revenue from notebook HDDs in the first quarter of fiscal 2023 was less than 1% of consolidated Marvell revenue. Looking ahead to the second quarter of fiscal 2023 and our consumer end market, we expect revenue to sequentially decline in the mid-single digits on a percentage basis and be flattish year over year. In closing, we delivered record results for the first quarter and are guiding for continued strong growth in the second quarter. We are seeing robust demand for our products, and our design win momentum remains strong.

With 88% of our revenue coming from beta infrastructure, we are confident that Marvell's favorable end market exposure makes us one of the best positioned semiconductor companies to benefit from strong secular growth trends. In the second quarter, at the midpoint of the range, we are guiding our revenue to grow by 41% year over year, which is almost entirely an organic comparison. We expect a strong operating leverage in our business model to drive non-GAAP EPS at the midpoint of guidance to grow by 65% year over year, significantly faster than our projected growth in revenue. As you heard throughout this call, our unique product cycles have been a big part of our above-market revenue growth.

As we look into the second half of this year and beyond, we are confident that our unique growth drivers in our cloud, 5G, auto and enterprise networking end markets, and our strong track record of execution through economic cycles will continue to be a source of strength. You'll remember from our prior calls and our investor day presentation that we have already won a significant number of design wins, which we are projecting will add a substantial amount of incremental revenue to Marvell going forward. While the external environment is challenging, Marvell's business continues to be strong, including strong bookings in our core data infrastructure end markets. As we move forward, we intend to continue to act as we always have, be diligent about changes, react promptly and manage our business and costs aggressively.

On behalf of Marvell's leadership team, I thank our employees for their dedication in driving stellar results. Our employees are the backbone of the company, and we are excited that Marvell recently ranked third overall on the list of Best Places to Work in the Bay Area by the San Francisco Business Times and Silicon Valley Business Journal. Even this award is so special because it is the employees who decide the winners. We have an outstanding team, and this award reflects our culture, values and dedication to creating a collaborative workplace which fosters creativity and innovation.

With that, I'll turn the call over to Jean for more detail on our recent results and outlook.

Jean Hu -- Chief Financial Officer

Thanks, Matt, and good afternoon, everyone. I'll start with a review of our financial results for the first quarter and then provide our current outlook for the second quarter of fiscal 2023. Revenue in the fourth quarter was $1.447 billion, exceeding the middle point of our guidance, growing 8% sequentially and 74% year over year. Datacenter was our largest end market driving 44% of consolidated revenue.

Enterprise networking was next largest to be 20% of total revenue, followed by carrier infrastructure at 18%. Consumer added 12% and the auto industrial at 6%. GAAP gross margin was 51.9%. Non-GAAP gross profit was $947 million or 65.5% of revenue, another record driven by rich product mix.

GAAP operating expenses were $681 million and include the cost of share-based compensation expenses. Amortization of acquired intangible assets, legal segment and acquisition, and divestiture-related costs. Non-GAAP operating expenses were $435 million reflecting the increase in R&D headcount and project expenses to execute design wins across all our data infrastructure end market. As we outlined at our investor day last year, we plan to continue to invest in R&D, given the tremendous opportunities we have in front of us, while keeping opex growth well below top line revenue growth to drive to our long-term target model.

GAAP operating income was $70 million, we achieved record non-GAAP operating profit of $512 million, up 123% from a year ago, and our non-GAAP operating margin was 35.4%. During the first quarter, our GAAP income tax expense was $205 million. This included the impact from a onetime non-cash tax charge of $240 million offset by other tax benefits in the quarter. The $240 million non-cash tax charge was due to the measurement of our net deferred tax asset as a result for obtaining and expansion of a lower foreign restriction tax incentives.

For the first quarter, GAAP loss per diluted share was $0.20. Non-GAAP income per diluted share was $0.52, up 79% year over year, exceeding the middle point of our guidance. Now turning to our balance sheet and cash flow. During the quarter, cash flow from operations was $195 million as we increased our working capital investment to support the top line revenue growth in a very tight supply chain environment.

The increase in working capital was primarily driven by increase in inventory, especially raw materials and work in progress help us manage it through ongoing supply chain disruption. We also made $86 million in payments during the quarter to secure long-term capacity with our suppliers. As of the end of the first fiscal quarter, our cash and cash equivalents were $465 million, and our long-term debt was $4.5 billion. Our gross debt-to-EBITDA ratio was 2.3 times, and net debt-to-EBITDA ratio was two times.

We returned $66 million to million in cash dividends and $15 million to share repurchase during the first quarter. Subsequent to the end of the first quarter of fiscal 2023 over the first three weeks of the second quarter, we repurchased additional $50 million of our shares through our 10b-5 program. We are pleased that we have restarted the share repurchase program as we believe it's in the best interest of the company and our long-term shareholders. In summary, the Marvell team executed exceptionally well delivering accelerated top-line revenue growth and strong earnings expansion significantly faster than revenue growth.

Turning to our guidance. For the second quarter of fiscal 2023, we expect the following results: revenue in the range of $1.515 billion plus or minus 3%. GAAP gross margin in the range of 49.6% to 51.9%. Non-GAAP gross margin in the range of 65% to 65.5%.

GAAP operating expenses to be approximately $669 million. Non-GAAP operating expenses to be approximately $435 million, which assumes that we will complete the acquisition of in the second quarter. For the second quarter, we expect non-GAAP tax rate of 6%. We expect our basic weighted average share outstanding will be 853 million, and our diluted weighted average shares outstanding will be 862 million.

As a result, we expect GAAP earnings per share in the range of $0.02 to $0.10. We expect non-GAAP income per diluted share in the range of $0.53 to $0.59. Operator, please open the line and announce Q&A instructions. Thank you.

Questions & Answers:

Operator

We will now begin the question-and-answer session. [Operator instructions]. Our first question is from Toshiya Hari with Goldman Sachs. Please go ahead.

Toshiya Hari -- Goldman Sachs -- Analyst

Good afternoon. Thank you so much for taking the question. And congrats on the strong execution. Matt, I was hoping you could speak to your expectations for the second half, both from a demand perspective and a supply perspective.

I think last quarter, there was a little bit of confusion as it pertains to the full year outlook. So if you can kind of confirm how you're thinking about your overall business, but particularly datacenter into the second half, that would be super helpful. And then again, if you have the supply to support the strong outlook. Thank you.

Matt Murphy -- President and Chief Executive Officer

Yes. Thanks, Toshiya. Great to hear from you. Yes, so we're pleased with the results and execution in Q2.

And -- I'm sorry, in Q1. And as you saw, we had a very strong quarter in datacenter, which I'll come back to in a minute. But just to kind of reframe from the demand side in all of our end markets, except consumer, we see very strong demand trends, Toshiya. Bookings have been very strong in the last two quarters.

Demand -- our demand outlook for the year continues to be strong. And with respect to datacenter specifically, we did have a strong Q1 better than expected. We still have pent-up demand and lack of supply there for the second quarter, but we expect actually a reacceleration in the datacenter in terms of our growth in Q3 and Q4, i.e., the second half. And on top of that, we have incremental new design wins that we've secured over the last 12 to 18 months, which we've sized roughly at, call it, $400 million incremental next year and $800 million the year after.

That's actually going to start layering in as well in the second half. So from our perspective, ex-consumer demand continues to be very strong. Datacenter in particular is going to have a great first half and a great second half. And then relative to supply, we really, first of all, credit to our operations team doing a great job in the first quarter, navigating all of the different impacts going on, in particular, in China and delivering a strong quarter.

Looking forward, we're starting to see the benefit of all the investment we put in over the last year into our supply chain. Whether that be the improvement in systems and tools, the relationships and the capacity that we've secured. And so we believe that, that's going to continue. And we do see a much improved supply outlook not only in the short term, as you can see from our results, both beating in our Q1 and then guiding strongly for Q2, but also in the second half, Toshiya.

And again, I think that's the result of a lot of hard work and transformation in our supply chain to meet our growth plans. So in summary, we have very strong demand driven by datacenter but also in 5G and automotive and the other things we've talked about and we've seen real improvements in our visibility into the supply we're going to get to go meet that customer demand.

Toshiya Hari -- Goldman Sachs -- Analyst

Great. Thanks for all the details.

Matt Murphy -- President and Chief Executive Officer

Yes.

Operator

The next question is from Chris Caso with Raymond James. Please go ahead.

Chris Caso -- Raymond James -- Analyst

Yes. Thank you. I wonder if you could talk a little bit about the enterprise networking business. And I guess it came in a little below your expectations, but yet you're still speaking about supply constraints in that area.

Is that a situation where your customers are supply constrained elsewhere and you're waiting for them? Maybe just give some explanation of the dynamics in that part of the business.

Matt Murphy -- President and Chief Executive Officer

Yes. Thanks, Chris. Yes, this was definitely a quarter where the mix wasn't exactly where we thought it was going to be from when we guided. As you could see, we overachieved in datacenter, and we underachieved on enterprise.

But as I pointed out in my comments, the delinquency and kind of the unfulfilled backlog relative to the size of the business is actually still the highest in enterprise. So this was really a case of just us being unable to execute our supply plan for the quarter nothing to do with demand. In fact, the demand from our enterprise customers continues to be very robust looking into the second quarter and throughout the year. So it was nothing to do with them.

They want more of our product. And you can see somewhat of a catch-up in Q2 with a very strong guide sequentially into the second quarter. But we see that continuing, Chris. So I know there's been a lot of noise out there around enterprise.

But from our perspective and talking to our customers, demand remains very strong. And in fact, we're behind in terms of our supply to catch up. But I think consistent with what Toshi was asking, we are looking to improve that in the second quarter and also through the second half.

Chris Caso -- Raymond James -- Analyst

Thank you.

Matt Murphy -- President and Chief Executive Officer

Yes.

The next question is from Gary Mobley with Wells Fargo Securities. Please go ahead.

Gary Mobley -- Wells Fargo Securities -- Analyst

Hey, thanks for taking my question. Congratulations on the good results. Wanted to ask about the supply situation and you just articulated improving supply coming online for the balance of the year. To what extent is that being driven by you perhaps giving your foundry partners a better forecast? How much of it is being driven by maybe you growing some more money their way in prepayments? And to what extent is it being influenced by some shifting of fungible capacity as the semiconductor market is no longer universally strong.

So maybe you're benefiting for redistribution of supply?

Matt Murphy -- President and Chief Executive Officer

Yes. Excellent question. And I think there's probably a piece of all of that. I think when I look back over what we've accomplished, one is we had to do a fairly significant education process across the supply chain of Marvell's prospects, how all the different pieces have come together from the different M&A we've done, our end market focus, etc.

And so I think we did a good job of that of getting the broader supply chain ecosystem to understand the Marvell opportunity. And so, to a large extent, they're betting on us and they're supporting our growth. And you can see that, right, just in terms of the year-over-year growth we're achieving, which by the way, is off of a pretty strong year we had last year. So that's clearly a factor.

We have also signed agreements relative to securing capacity. And you can see some of those that have shown up in our Q or 8-Ks we've issued partnerships we've entered into. So some of that has been down payments and supply agreements to ensure that we have the right capacity. I think that's some part of it.

And then it's hard to say, but on the last part of it, the sort of fungibility that may be coming into play a little bit, but it's too early to say. And quite frankly, the supply we're seeing today is we can really mostly attribute that to sort of our own effort. I will say, and just to be very clear for everybody on the call, we're not out of the woods here. Our unfulfilled backlog has continued to grow each quarter.

We're definitely working that down. We're focused very much on the end demand and shipping to the right people. And we feel like we've done a good job of that in terms of keeping our customers' lines moving and not causing impacts and being very agile. But I think to the extent that on that third point, the fungibility side, if there were to be a true reduction or capitulation, let's call it, the PC and consumer end market and not needing all the supply they've consumed, that certainly could be an incremental thing we could look at in the second half.

But that -- that's not quite there yet, but maybe some of it is. We do see pockets of things opening up, but it's really hard when you sort of drill into it where it exactly came from. Hope that's helpful. Kind of a combination that you sort of nailed it comes of the mid.

Gary Mobley -- Wells Fargo Securities -- Analyst

Thanks, Matt.

The next question is from Timothy Arcuri with UBS. Please go ahead.

Timothy Arcuri -- UBS -- Analyst

Hi. Thanks. Matt, I have just a broad question kind of on demand signals. To some degree, because supply has been so tight, it does create the potential that some of the orders, and I'm not saying for you, but I'm just saying broadly, are being placed just to secure their spot in line and not really backed by underlying sell-through at the customer or even the customer's customer level.

And it sort of creates the risk that the chip companies are going to see more of a delay in sort of the demand signals at this time. I think it's less of a risk for you. But I guess my question is, how do you assess that as a risk? And really, the question, I guess, is on the tenor of your discussions with your customers? Do you get the sense that there are some examples of customers placing bookings just to get in the queue because you have such long lead times? I asked because some of the big large cloud customers are beginning to slow some of their hiring, things like that. So I'm just wondering what the tenor is of your talks with them.

Thanks.

Matt Murphy -- President and Chief Executive Officer

Sure, Tim. Yes. No, it's not unlike other cycles, where certainly the phenomena you point out, and this is the investor concern, right, more broadly in semis is have customers over-indexed on their order placements. And what happens when demand stops or slows down.

So we've taken this very seriously. I mean I just did a pretty much half a day review in the last few weeks with my entire team going through each of our product lines, going through to the customers and really kind of working through at an individual level where we still see the demand? Do we see any inventory building up? If so, what does it look like in that type of an exercise? And what I can tell you is there's no real examples I could point to, Tim, or anything thematic. I guess in some ways, we may have the benefit that we've been somewhat behind although I think we've done a good job of keeping everybody's lines moving. But certainly, we haven't been the company that's been swimming in capacity.

So I think as we look out now, especially where the kind of global economy is beginning to moderate. We're able to kind of take a look now and do a refresh, especially with our improved supply situation and really make sure we're allocating it to the right people. So it's a very active process, Tim, but I can't give you any nuggets of specific examples where I think thematically inventory may be building. But I guess I would conclude by saying we did -- we were pretty transparent in the prepared remarks about what we saw in the consumer segment, which albeit it's 12% of the business.

And of that, a smaller portion of it is really exposed to what I would call kind of true consumer like PCs and things like that, but that did very much slow down. There definitely was a change in demand. And as a result, some supply that had there some inventory that had built up but we've got other moving pieces even with consumer that's sort of offsetting it. So a long way of answering it.

I don't have any great examples, but we're on it. We're watching it. But I'd say the bulk of the meeting, to be honest, when I had it was the demand signals being very strong, right, across the cloud companies across our 5G business, enterprise wired. There's a lot of great opportunities for us.

And a lot of this, Tim, is driven on Marvell's product cycles. It's not necessarily an end market phenomena we're dealing with here. It's really the new product ramps that you're very aware of across these different segments, and those seem very much intact in aggregate.

Timothy Arcuri -- UBS -- Analyst

Thanks, Matt. Yes, I mean, I think in the continuum of companies that have risk, you're at the kind of bottom of the list. But thanks for the questions or the answers. Thanks.

Matt Murphy -- President and Chief Executive Officer

Yes.

The next question is from Vivek Arya with Bank of America Securities. Please go ahead.

Vivek Arya -- Bank of America Merrill Lynch -- Analyst

Yes. Thank you for taking my question. Just wanted to clarify, Matt, if you have seen already or are baking in any supply or demand effects of the China lockdown or Europe turmoil. But my bigger question is, how do we conceptually align this notion of rising delinquency or unmet demand with rising inventory at both on semiconductor company balance sheet and even at some of the large networking OEMs, at what point does this rising inventory across the supply chain start to become a concern?

Matt Murphy -- President and Chief Executive Officer

Great. Thanks, Vivek. Yes. On the first question, again, we're -- as you know, based on the timing of our reporting, we're like everybody else who's going right now.

We had the month of April to comprehend in there relative to the China lockdown. And we navigated it really well. I think one of the reasons for us is that when COVID first happened, when the pandemic first began and there was major lockdowns everywhere China, including and also Southeast Asia, our operations team did a really good job of building up supply chain redundancy and resiliency over the last two years. So effectively dual sourced almost everything we can coming in and out of China and even some of the other regions over there.

So there was some impact. There was a little bit of product revenue where could we have gotten supply out of China, we could have fulfilled it, but it was very small, Vivek, to be honest with you. So we're able to be fairly agile in terms of moving things around. So that was a positive.

On the war in Ukraine and the impact on kind of in the again, I think you're hearing the data points, right? We don't see it directly, but certainly on the slowdown in the consumer segment, people's budgets being pinched, things like that. I think that's part of the issue with some of the consumer end market commentary. Again, we're not really in there. And we don't have operations in Ukraine or Russia.

So we didn't really have any impact on that. So I think we're OK there. On the commentary on rising inventory, look, I'm very aware of this. You can pull everybody's Qs out and look at -- and one simple thing we do is look and OEM companies' inventory growth.

And you can see across a wide range of companies and industries, growth in inventory far exceeding revenue growth. So that is something we're paying attention to. We're using that to dive in deep with our customers. But I would say that our view tends to be like a lot of our customers, which is the end demand, especially in enterprise, in cloud and in our product cycle in 5G, the demand looks pretty strong.

But there is -- there are missing pieces. There is the golden screw issue for sure that some of our customers have. We're just trying not to be the golden screw and also be very kind of clear eyed about where the inventory is and what does that mean for Marvell. And so I can tell you is we're digging into it at a part level detail and making sure that we're being prudent about where we allocate the supply.

But it is something we got to keep watching for sure.

Jean Hu -- Chief Financial Officer

Yes. And to add to what Matt said is we actually chose to increase our inventory to support the revenue growth in the second half. We have a very broad set of product lines, and we see strong demand. So the flexibility we need to have raw materials and the way to support the revenue growth is really critical.

So we did choose that to make sure we can support the customers and the future revenue growth.

Vivek Arya -- Bank of America Merrill Lynch -- Analyst

Do you have a target, Jean, on days of inventory?

Jean Hu -- Chief Financial Officer

The current level is what we are comfortable. We think we can help and manage the supplies for the second half. I think if the environment is normalized, we definitely will have a lower inventory like 120 days. That's what we think we should keep.

But right now, we definitely chose to increase it to provide more flexibility.

Vivek Arya -- Bank of America Merrill Lynch -- Analyst

Thanks very much.

Matt Murphy -- President and Chief Executive Officer

Yes. Vivek, just to chime in on Jean's comments, I fully agree. If you look at just the steepness of the revenue ramp we're dealing with. Clearly, the WIP has to go up, right, just to sort of support the growth.

So that part we're comfortable with. And given the given the lockdowns and all the volatility, I think having that extra inventory carry for us is very prudent. And we watch it, and we'll certainly work it down. But I don't think you're going to see many companies go back to the good old days of 80 days or something like that, unless they truly get into trouble.

I just think for a while, we're all going to have to be mindful that there's a lot of volatility in the world. But we're sort of in the range now, and we're very conscious in terms of what we're doing here.

Vivek Arya -- Bank of America Merrill Lynch -- Analyst

The next question is from Matt Ramsay with Cowen. Please go ahead.

Matt Ramsay -- Cowen and Company -- Analyst

Yes. Thank you very much. Good afternoon. Matt, in part of your script, you had talked about the upcoming server launches that include a couple of new technologies, right, and then some CXL support for shared memory.

And I think you guys have done a great job of articulating what that might mean for your Accelerator business and given us some outlook there. I was curious if you might explain a little bit about what PCIe 5 might drive for support of that technology into the storage and network peripherals. Is that material to the growth in the back half? And how much visibility do you have there? Just -- and then just a quick follow-up, question I get all the time is visibility on cloud capex. If you guys look out in your cloud business, is it quarters, years? Like how long are we talking that you feel like you have visibility because there's definitely some concerns there.

I appreciate it. Thank you.

Matt Murphy -- President and Chief Executive Officer

Hey, Matt. Good to hear from you, and good questions. Yes, I think you did nail it on one of the more important aspects of the upcoming CPU cycles is the IO, right, and the release of PCIe Gen 5 and we've certainly been preparing for that. That is a key part of the equation for us, particularly, as you can imagine, in our storage business and our datacenter storage business, which One of the key things we have to align to on our product roadmap is obviously nailing the PCIe IO road map, and it's not a trivial thing, not only the controller, but obviously the PHY and getting everything qualified and working.

And so our team has done a great job there. We're very well positioned in storage on PCIe Gen 5 actually said in my remarks, we've already got wins lined up on Gen 6. That's still a ways out, but that's going to be another leg of growth. And you're right, the PCIe standard is really going to be the fabric and the interconnect that CXL runs on top of.

And so a lot of the effort we put in on both Gen 5 and in the future, Gen 6 is going to give us tremendous leverage as we think about disaggregation, particularly of memory and these different solutions that are going to emerge around CXL. So it's very strategic. We do -- we always make make-or-buy decisions on things in terms of make versus buy, sorry, on technologies, but this is one, particularly on the PHY layer for PCIe that we've -- we do ourselves, and we have -- we're best-in-class in what we do here, and then we leverage that into our larger SOCs. So -- but I think the biggest impact from Marvell will be just driving broader adoption of our data center flash controllers, which again, are well positioned across a number of NAND OEMs.

And products defined directly with the cloud OEMs going back several years, right, to get all this lined up. So it's going to be a good cycle for us. And then sorry, on cloud capex, I don't have any insight. I -- we certainly look at all the publicly available data.

The most recent update certainly looked promising. But I would say for Marvell, Matt, and for the rest of the investors on the call, we're -- of course, the overall capex environment in cloud can certainly be a tailwind and that could be a headwind for anybody that supplies into there. But -- you got to remember, most of our revenue coming from the cloud is really in new product cycles that are very Marvell-specific in some cases. I mean, let's take let's take PAM, for example.

If you went back a year ago, you really had a couple of companies deploying it versus older NRZ-based solutions. You head into this year, there are now additional companies as well that are going to be driving that cycle on 200 and 400-gig. We have new applications like even 800-gig as an example, for AI clusters and things like that where we started ramping our 800-gig product. So whether the capex goes up or down, there's new applications and new replacement cycles that are going on.

And then there's just other things like, for example, in our Cloud Ethernet switch area, right? There was new wins we got through the Innovium team that joined us last year. We expect continued strong growth from that product area. We have new cloud optimized silicon in ASICs and DPUs that were designed in over the last couple of years. Those are going to be ramping up.

So we are very -- we're paying attention to it, Matt, but I would say that that it's a little bit like our 5G business. You can see things go up and down and lumpiness in the market. But when you have a strong product cycle with either content or share gain and new customers coming on, you can power through and that's our full expectation in the cloud. We have very strong conviction on our business there today, particularly in the second half and next year relative to the cloud hyperscale and we'll watch the capex trend, but most of our products are independent of that trend.

The next question is from Ross Seymore with Deutsche Bank. Please go ahead.

Ross Seymore -- Deutsche Bank -- Analyst

Hey, guys. Thanks for letting us ask a question. Jean, I wanted to ask you one on the margin side of the equation. You guys always run a very tight ship in this, but there's lots of moving parts.

Matt's talked a lot about more supply coming on in the back half of this year. Sometimes that can come at a higher price these days. And then even the opex side of things, wage inflation, etc., and some acquisition integration that you talked about. So generally speaking, can you walk us through the puts and takes on the gross margin and the opex side of things for the rest of the year?

Jean Hu -- Chief Financial Officer

Yes. Ross, thanks for the question. I think our team has been very disciplined to manage opex to make sure we follow our overall business model right, grow revenue significantly faster than opex growth and keep the gross margin right in the middle or even above the middle of our long-term target model, so we can drive the earnings expansion much faster than top line revenue growth. When you look at the opex in Q1, as I said earlier, we increased headcount and project expense to really execute on all the design wins we have won.

Q2, it's we keep it flat. In the second half, it's going to go a little bit higher, slightly higher, but it's largely because we are going to grow revenue in second half to support the revenue growth, you have certain variable expenses that will increase slightly in second half. In the longer term, you should continue to expect us to drive top-line revenue growth and opex around 50% slower than top line revenue growth. So we can continue to get the earnings expansion.

So in Q2, if you look at the midpoint of our guide, our operating margin is already above 36%. We are very, very driven to get our operating model to the 38% to 40% range.

Ross Seymore -- Deutsche Bank -- Analyst

Next question is from Tore Svanberg with Stifel. Please go ahead.

Tore Svanberg -- Stifel Financial Corp. -- Analyst

Yes. Thank you, and congratulations on the strong results. Just had a follow-up on the storage question, but this time on Gen 6, not on Gen 5. So just, Matt, can you maybe frame a little bit Marvell's positioning here? I mean I think about the PAM4 IP you have, obviously, you talked about CXL.

I know it's still early days, but if you could just frame a little bit sort of layman's terms, you're positioned for PCI Gen 6, that would be great. Thank you.

Matt Murphy -- President and Chief Executive Officer

Sure, Tore. Yes, Gen 6, as it relates to storage, you're absolutely right. Given the increase in IO throughput and data rate, you had to move to a PAM-based architecture. So that's played right into our strengths.

We've coupled that with our -- and we were early to do this, by the way, with our five-nanometer technology platform. And so there's just a whole lot of goodness and reuse there, as you can imagine. And it really put us in a strong position to get there early, and I give our storage business unit, a lot of credit for really having thought leadership here. I mean they probably jumped like two nodes on everybody, not that it's a whole node game, but in terms of just the power and the performance that we're getting out of these solutions.

And then, of course, the benefit we get to take the IO down to five-nanometer and leveraging PAM is actually a huge help, right, just given the given the complexity. And you saw that in our optical business, right, and kind of how Inphi drove performance over time as they've driven PAM on new process node, same thing over here. So I think that's going to be very strategic. And Yes, I think that that platform now -- again, we're early, right? We're just talking about launch today, but we do like to give color on our future leaning roadmap.

But it definitely plays to our strengths. And I think as you think about also what's going to be required in CXL. I think even things like closing the link and the need for retimers and redrivers, accelerators, pooling applications, they're all going to require robust Gen 6 IP and then be able to integrate those into various different SoCs. And I would just say even today, the CXL activity we're seeing in terms of our design opportunities is pretty broad, and it's almost all -- it really is all in our five-nanometer platform.

So it all kind of hangs together, Tore, and maybe I think you sort of see this, but I think others are as well. The combination of all the IPs that we brought together through the different acquisitions plus the Marvell technology platform has really created an opportunity for us to go-to-market with these semi-custom solutions and be very successful in this next wave of cloud optimized silicon.

Next question is from Harlan Sur with J.P. Morgan. Please go ahead.

Harlan Sur -- J.P. Morgan -- Analyst

Good afternoon. Great job on the quarterly execution. I saw the announcement on -- and you mentioned this map on shipping 100,000 400-gig coherent DSP chipsets. You're pretty early days in this transition, but you guys have already shipped like according to my calculation, almost $200 million plus worth of products.

And the great thing about this family of products is that they've got the same underlying architecture and you've taken that and you're going after different markets, right? Datacenter interconnect with for 400 ZR, long-haul metro with your 400-gig Canopus solution. The adoption seems to be actually on a faster curve. Is this a driver of the upside in your datacenter and carrier franchises? And then I believe that your deployment is being driven by just one cloud titan, are you guys anticipating other cloud titans starting to fire as the year unfolds?

Matt Murphy -- President and Chief Executive Officer

Yes. Thanks, Harlan, for the question. And maybe just to start at the top on coherent DSP. I'm not sure everybody quite understood.

Even the Inphi people that followed Inphi closely, how strategic this technology is. A little bit of background. They had had their own effort in coherent Inphi, and they ended up acquiring a company called ClariPhy a few years before we acquired Inphi. And ultimately, they chose to ClariPhy coherent DSP road map.

This is very, very difficult stuff to do, Harlan. And once you get it right and get it designed in, these are very, very long product life cycles, particularly in the metro long-haul type of markets, the telco type markets. And that's really what's driving -- that's really where the revenue is showing up today for this. The added benefit is obviously the same technology and chips are used in the ZR 400 the ZR market as well for DCI.

So there's a double benefit here. And so on the merchant side, we're a strong leader. We have a road map, obviously, beyond this to 800-gig. That's going to play in well to our next-generation DCI products as well.

And then even longer term, there's discussions longer term about the modulation technology eventually inside datacenter moving to coherent. So it's a very strategic technology for Marvell. And to answer your question on the ZR DCI side, we -- and I said it in my prepared remarks that it might have begun lost, but we do have multiple customers for this, not just one. And those will be ramping up over the next year or so, the additional customers.

We're already shipping and putting out record results on the DCI products as it is. We're really driven by one customer, but there's more coming. So we're pretty excited about this. And we have a whole ecosystem lined up, right? We have a number of module partners for different applications.

And so -- anyway, yes, it's something we'll be talking about more. Maybe we'll do a tech talk on that one, too, Harlan, but it's actually a really important technology that we got from Inphi. And it's obviously an outstanding team that really feeds a lot of the other things that we do inside the company.

Harlan Sur -- J.P. Morgan -- Analyst

Yes. Great insights. Thank you, Matt.

Matt Murphy -- President and Chief Executive Officer

Yes. And just one final thing, I would say, remember, too, this is a chip set as well. So it's not just the DSP, it's the driver, it's the TIA and there's even other components we're looking at to really optimize the solution. So when you hang all that together and you can deliver it as a platform.

It's very powerful.

Harlan Sur -- J.P. Morgan -- Analyst

Perfect. Thank you.

The final question today will be from C.J. Muse with Evercore. Please go ahead.

C.J. Muse -- Evercore ISI -- Analyst

Yes, good afternoon. Thank you for taking the questions and squeezing me in. I guess a question on gross margins. You guided down 25 bps sequentially.

Obviously, a very small amount. But just curious if there's anything mix-wise and/or higher input costs that we should be thinking about there? And then just as a quick follow-up to Jean, are we at the net leverage level now where you plan to return free cash flow via buybacks? Or is that still in more of the opportunistic phase? Thank you.

Jean Hu -- Chief Financial Officer

Yes. So C.J., thanks for the question. First, on the net leverage, if you look at our Q2 guidance at the middle point of our guidance our net leverage ratio will be below two, gross debt-to-EBITDA ratio will be around two, but the net leverage will be below two. As I said earlier, we have restarted share repurchase program even after end of Q1, subsequently, we did purchase additional $50 million through our 10b-5 program.

So our capital allocation principle is still the same, right? We want to invest, but we are also committed to return more than 50% free cash flow to shareholders, primarily through share repurchase. On the gross margin, our gross margin, we are very pleased with the Q1 gross margin, which is a record in the Q2 guide it's all both above middle point for our long-term target. So the Q2 is really just a mix. We have so many different product lines quarter over quarter, you will see the mix change up and down of our middle point I would not predict that closely.

But in general, it should be around 65% sometimes higher.

Matt Murphy -- President and Chief Executive Officer

I'll just add, C.J. I totally agree with Jean, obviously. And just to remind everybody, we set a range of -- on gross margins as our target model of 64% to 66%. We had a record 65.3% in Q4.

Then we had another record of 65.5% in Q1, and then we're guiding 65.25% if you look at the midpoint in Q2. So it's kind of in in the range, if you know what I mean, I think run the company around that 65-ish is a really good place to be. If we can continue to grow the company the way we're growing it and drive leverage and drive design wins and stay competitive. So I think it's -- I think we're in pretty good shape.

I think obviously reasonable to ask the question, but I think, as Jean said, we're going to have little movements here and there on mix. And we're ultimately just focused on keeping it in the right range in the right strike zone and then just driving really strong top-line growth and driving operating leverage through the cycle we're in here.

C.J. Muse -- Evercore ISI -- Analyst
