Great. Thanks, Ashish, and good afternoon, everyone. Let me start with a quick recap of Marvell's financial highlights for fiscal year 2020. Our GAAP revenue was $2.7 billion, GAAP gross margin was 50.3%, and GAAP income per diluted share was $2.34. On a non-GAAP basis, our gross margin was 63.3% and non-GAAP earnings per share was $0.66. Fiscal 2020 was clearly a challenging year for the semiconductor industry. But against this backdrop of macroeconomic uncertainty, Marvell continues to take bold steps towards becoming a leader in infrastructure solutions. Not only did we achieve the complete realization of synergies from the integration of Cavium in the first quarter of fiscal 2020, 2 quarters ahead of schedule, we announced and closed 3 additional strategic transactions within the year. We acquired Aquantia and Avera and divested our Wi-Fi business. In fact, the integration of Aquantia and Avera is well ahead of plan and this is reflected in our lower OpEx expectations for the first quarter of fiscal 2021, which Jean will discuss in her section. Implementing all the key learnings from the Cavium acquisition, our IT and operations team did an amazing job in completing the ERP integration of Aquantia in 1 day and Avera within 5 days of closing the transactions.
In addition to the portfolio transformation, we won a number of key designs in fiscal 2020, which we expect will fuel multiple years of revenue growth for the company. In wireless infrastructure, we started ramping our first-generation of 5G processors at Samsung, won their next-generation 5G baseband processor; and yesterday, we announced an even deeper collaboration with them. During the last year, we also won a fronthaul interface chip and entered into the radio head with processors from massive MIMO.
Equally exciting, earlier today, Nokia announced an expanded relationship with Marvell on 5G infrastructure solutions, which I will discuss later in the call.
In Ethernet connectivity, we won a number of designs at leading networking OEMs with our switch and PHY solutions. In storage, we started to ship and ramp preamps and controllers into high capacity 16-terabyte near line drives and secured the follow-on controller for the next-generation platform, targeting higher capacity points, well into the 20-plus terabyte range.
We released our NVMe over Fabric Ethernet SSD controller and a family of PCIe Gen 4 NVMe SSD controllers, which are also powering our first major DIY win. As we start fiscal 2021, we are excited about a number of product ramps, but are also trying to assess the near-term impact from the coronavirus.
Clearly, the safety and well-being of our employees is our highest concern, and I want to express my sincere support for all our people in China who have been the most impacted. Prior to the outbreak gaining intensity, our bookings and backlog were getting stronger going into fiscal year 2021, driven by our own product cycles, such as the start of our 5G product ramp, our success in nearline drives and a recovery in our core business. In addition, the signing of the Phase 1 trade deal between the U.S. and China was helpful in erasing trade tensions, which had affected our business last year. But recently, as the virus impact has become broader, we have started to see supply chain-related impacts to our business.
It is impossible for us to fully quantify the effect of the situation as our business -- on our business as it remains fluid. However, our revenue guidance for the first quarter includes a 5% reduction based on what we know so far. In addition, given the ongoing uncertainty, we have also temporarily widened our guidance range on revenue from plus or minus 3% to plus or minus 5%.
Let's move on to our quarterly performance. During the fourth quarter of fiscal 2020, we delivered solid results and achieved $718 million in revenue, above the midpoint of the revised guidance we had provided on December 6, after we completed the divestiture of our Wi-Fi business. Our GAAP income per share was $2.62, and our non-GAAP earnings per share was $0.17.
First, in our networking business, revenue during the quarter was $377 million and grew 14% sequentially. The double-digit growth was primarily due to full quarter contributions from the Avera and Aquantia acquisitions, partially offset by the divestiture of Wi-Fi. Both of our recent acquisitions were off to a running start with the Avera ASIC business delivering a solid quarter, and Aquantia's revenue trajectory continuing to improve as those customers completed inventory digestion. The bookings trends for both of these acquisitions support the full year expectations we had communicated last year.
While the Avera design team continues to work on completing designs they had won prior to the acquisition, they are also engaging with existing Marvell customers who had not worked with them in recent years. The overall opportunity pipeline for Avera is very healthy and continues to broaden. Outside of the 2 acquisitions, wireless infrastructure shipments remain strong and enterprise performed as expected. In addition, we experienced strong booking trends in networking before the recent coronavirus impact clouded the outlook. While we assess the impact from this event, we continue to make progress on securing additional design wins in a number of key end markets.
I'll start with the wireless infrastructure market. Yesterday, we announced an extension of our long-term collaboration with Samsung across additional segments of the radio access network. We have been working with Samsung closely to deliver multiple generations of baseband and Control Plane solutions for both 4G and now 5G base stations, incorporating their intellectual property with Marvell's OCTEON and Fusion processors. More recently, we have also been partnering with them on innovative radio unit architectures designed to meet the dramatic increase in compute power required for the complex beamforming algorithms inherent to massive MIMO deployments.
Equally exciting, earlier today, Nokia announced that we are broadening our relationship for the development of multiple generations of custom and multi-core ARM-based infrastructure processors for 5G. This is another example of the partnership model we offer, which enables our customers such as Nokia to integrate their unique technology into our programmable processor platform to develop customized products. It's really the best of both worlds, as our customers can focus their internal resources on their differentiated technology and embed that IP into the chipset. This significantly accelerates their time-to-market by utilizing other parts of the SoC subsystem from Marvell, such as the processor complex, which we have already developed and hardened for base stations.
We are able to deliver this degree of customization with our field-proven, flexible SoC architecture in our Fusion products comprised of ARM cores, a variety of DSP cores tailored to our customers' requirements and customer developed IP blocks stitched together very efficiently by our unique interconnect to maximize performance. This programming model enables our customers to differentiate their solutions to their own IP and algorithms. In addition to providing the underlying architecture for our customized Fusion solutions, our OCTEON multi-core ARM-based infrastructure processors also provide control and data plane processing.
We are looking forward to growing our business with Nokia as they benefit from the growing 5G wireless infrastructure market. We expect to start shipping the first custom product later this fiscal year, and we are also starting development of the next-generation of infrastructure processors and custom SoCs. In addition to the progress we are making at multiple Tier 1 wireless customers with our existing platforms, we are continuing to innovate in this market and are working with analog devices to pair their world-class RF transceiver technology with our broad digital 5G platform.
We both recognized the growing complexity in 5G radio units with the proliferation of technologies, such as massive MIMO, which is driving an increased need for the very close collaboration between the RF and mixed-signal portion with the compute domain. This unique collaboration between the 2 best-of-breed suppliers will provide customers with significant improvements in size, power and performance within the increasingly complex radio unit.
Before I move on from the wireless infrastructure market, let me spend a couple of minutes going over our perspective on the rollout of 5G, including the key drivers, the frequency bands in play such as sub-6 gigahertz versus millimeter wave and the pace of deployment.
First, Why 5G? Very simply, it significantly lowers the cost per bit of wirelessly transporting data, which benefits both carriers from an OpEx perspective and consumers by enabling a better user experience. Our base assumption is that for the next few years the overall wireless CapEx envelope will remain similar to historical patterns, but the better economics of 5G will inevitably transition wireless CapEx away from legacy 4G technologies. Even under this flattish CapEx assumption, we expect to drive significant revenue growth as our content and share in 5G is considerably higher than what we had in 4G. Over time, we expect that 5G will also create newer opportunities beyond the handset, which could drive an upward inflection in CapEx, and that would represent an upside to our base case. On the subject of sub-6 gigahertz versus millimeter wave, while we believe that both modes of deployment will see significant activity over the next few years, our view is that the vast majority of 5G base station CapEx will be spent on sub-6 deployment.
A leading industry analyst has a similar forecast projecting that over 95% of the spend to go towards sub-6 deployment. Accordingly, we expect our wireless infrastructure revenue to follow a similar pattern and primarily derive from macro base stations. Having said that, as the small cell market develops in 5G, especially for millimeter wave applications, we are ideally situated to address these opportunities with our multi-core processor architecture, which can easily be scaled down to the relatively lower power and performance footprint needed in small cells. Our platform also enables significant software reuse for our customers as they scale down their macro solutions. We have a full set of capabilities for the wireless infrastructure market, including baseband, transport, Ethernet connectivity and DFE ASICs, making us the ideal chip provider for small cells, which are likely to require the integration of multiple functions in a single-chip or package for power and space considerations.
In terms of timing, this is an infrastructure business where shifts from one technology to another are typically over a multi-year period, with the rate of adoption constrained by flattish CapEx budgets. We're at the very beginning of a multiyear transition to 5G, and the vast majority of this opportunity is in front of us. As you are aware, Korea is the only major geography, which started 5G deployments in earnest in calendar 2019. And while Korea is an important region for our lead customer, most of their base station shipments in 2019 used FPGAs for processing, and they only started to transition to our solutions late in the year. As a result, we expect significant revenue growth this fiscal year from deployments by Korean operators, and these deployments will continue for a number of years.
Additional growth opportunities are also in front of us from geographies such as Japan and the U.S., when they start to deploy 5G later this year. With respect to China, Marvell historically had very limited exposure to their wireless infrastructure market; however, with the Avera acquisition, and our own organic efforts, we are now better positioned to also participate in China's 5G deployments.
In summary, the wireless industry is starting to see a convergence of factors important for 5G adoption, including a more mature supply ecosystem, both on handsets and base stations and the opening up of additional spectrum, especially in the important sub-6 gigahertz bands. This combined with the better economics of the newer technology is increasingly driving carriers to shift their CapEx to 5G base stations, especially in regions where they are considering turning on 5G services in the near future.
New 5G base stations are, of course, backward compatible with 4G and allow carriers to future-proof their networks rather than continue spending on legacy technologies. So as a result, we expect that wireless CapEx will continue to accelerate to 5G on the infrastructure side. Now let me shift gears from the 5G deep dive. We just announced our next-generation of ARM-based infrastructure processors, our OCTEON TX2 family, targeting a wide variety of networking equipment, including switches, routers, secure gateways, firewalls, network monitoring, smartNICs and base stations. This portfolio delivers 2.5x performance improvement over the prior generation and can scale up to 200 gigabits per second of packet processing, scaling from 4 cores at the low end to 36 cores for the most demanding applications.
Compared to solutions processing data only on CPU cores, OCTEON's configurable and programmable hardware accelerator blocks, which include security, packet processing, traffic management functions provide a much better balance between power and performance in networking applications. In fact, we have already started shipping production -- we started production shipments of our OCTEON TX2 processors into our lead wireless infrastructure customer.
Our Ethernet switch and PHY products continue to win new designs in their target markets. As a reminder, our Ethernet switch strategy has been to expand beyond our enterprise campus position into the enterprise core and aggregation layers and into service providers. We play to our strengths in offering feature-rich products and do not target the pure speeds and feed sockets in the hyperscale data center market where there was already strong incumbency and a large networking OEM that announced their plan to offer internal ASICs directly to cloud customers. Our ARM server products and our automotive products also remain well positioned for growth later this year.
Now let me discuss our projection for our networking business in the first quarter of fiscal 2021, as compared to fourth quarter results. Please keep in mind that our fourth quarter results included approximately 5 weeks of revenue from the now divested Wi-Fi business. Therefore, I'll first provide you with our revenue expectation for the continuing networking business, which we project to grow sequentially by approximately low single digits on a percentage basis from fourth quarter results adjusted for the divestiture of Wi-Fi. We expect this growth to be led by new product ramps in enterprise and cloud data center applications while we project flattish revenue from the wireless infrastructure market. Please note that this growth outlook includes the negative impacts currently known from coronavirus-related issues.
To help you clearly model this outlook, let me also provide you with the projection for first quarter results as compared to our reported fourth quarter networking revenue of $377 million, which included the 5 weeks of Wi-Fi. Compared to this reported result, we expect networking revenue in our first quarter to decline in the low to mid-single digits sequentially on a percentage basis.
Now let me turn to our storage business. Storage revenue for the fourth quarter was $296 million and grew 3% sequentially, stronger than our expectations. The sequential growth was driven by an increase in demand for both of our storage controller product lines. Specifically, our HDD business continued to benefit from our growing position in the nearline market and our enterprise and data center SSD business continued to recover in the fourth quarter. These data center-led growth drivers more than offset the expected decline in the client market. Our fiber channel business remains strong and stable from the third quarter.
As you may recall, at our prior investor days in 2017 and then again in 2018, we had articulated a storage strategy to focus on the enterprise and data center market and become less reliant on the client market.
In our HDD business, we projected the client business to secularly decline as the shift towards SSDs and PCs accelerated and that we plan to focus on the growing nearline market. In addition, we shifted investment in our SSD business towards higher performance and stickier enterprise and data center solutions and DIY opportunities and away from the commodity client market, where margins were less attractive, and some of our customers were increasingly in-sourcing controllers. At this point in time, we believe that the bulk of the decline in exposure to the client market, including the impact of client SSD controller in-sourcing at some customers, is mostly behind us. We estimate that our total client revenue exposure collectively across both HDD and SSD controllers, starting fiscal 2021, is only 5% of the entire company's revenue. For context, at our Investor Day in October 2018, client storage was approximately 14% of total company revenue.
In fact, sequential storage revenue growth in both the third and fourth quarter of fiscal 2020 was driven by our enterprise and data center products. The next phase of our storage growth strategy we had outlined was the emergence of the DIY market for custom SSD controllers, and we are now a couple of quarters away from mass production of our first major design win.
We also expect to continue to ramp our preamplifiers for HDDs over the next couple of years. Our recently introduced 12-nanometer PCIe Gen 4 SSD controller continues to receive strong interest from multiple customers, including several NAND OEMs for its optimized blend of high-performance and low power in a small form factor.
Our Ethernet-based storage solutions are gaining momentum, and we just announced we are partnering with leading ODMs, Accton and Foxconn to bring our Ethernet Bunch of Flash or EBOF technology solutions to market. As you may recall, at FMS 2019, we demonstrated our NVMe over Fabric Ethernet SSD controller. This product enables a disruptive new data center architecture by directly connecting SSDs through a switch to an Ethernet network, without the need to go through a host, such as a server. These EBOF platforms will start sampling the spring and incorporate Marvell's NVMe over Fabric SSD controllers, Prestera Ethernet switches and up to 48 SSDs in a single chassis.
In aggregate, we believe the growing footprint of our enterprise and data center storage controllers and preamps, upcoming ramp of our SSD DIY controllers and progress of our Ethernet-based storage initiatives, collectively positions our storage business for long-term success. Looking to the first quarter for our storage business, which is generally a seasonally down quarter for this end market, coupled with virus-related impacts to this business, we expect revenue to decline sequentially in the mid-single digits on a percentage basis.
Let me close by thanking the more than 5,500 Marvell employees around the world for executing extremely well under difficult macroeconomic conditions. I am looking forward to an exciting fiscal 2021 to capitalize on the multiple growth initiatives we have been investing in over the last few years. Fiscal 2021 also marks an important milestone for Marvell, as we celebrate our 25th year anniversary. It has been a long and eventful journey, most recently punctuated with the company's transformation as we pivoted towards the infrastructure market. The financial community has been well aware of our journey, and we have now started to share our story with a broader audience. We held our first industry Analyst Day in early December, and the reception was outstanding. We received clear feedback that our story needs to be told more broadly as they see Marvell in the midst of multiple major trends, including 5G, AI, cloud and connected autos.
We will continue to spread the message and are scheduling our next Investor Day for October 6 in New York, where we will provide an update on our progress towards our long-term goals. I look forward to seeing many of you at that event.
And with that, I will turn over the call to Jean for more detail on our recent results and outlook.
