Sanjay Mehrotra
President and Chief Executive Officer at Micron Technology
Thank you, Farhan. Good afternoon, everyone. Micron delivered record annual revenue in fiscal 2022 with solid profitability and free cash flow, despite a challenging environment in the latter part of the year. In 2022, we ramped our industry-leading one-alpha DRAM and 176-layer NAND nodes across our portfolio and returned a record amount of cash to shareholders. We strengthened our product portfolio significantly during the year as evidenced by a record revenue in mobile, auto, industrial and networking end markets. Our share gains in client and datacenter SSDs contributed to record revenue in SSDs and also in our consolidated NAND business. We also ramped new product categories like high bandwidth HBM2e memory and GDDR6X. In addition, a record number of customers recognized Micron as the industry leader in product quality.
Our fiscal Q4 financial results were impacted by rapidly weakening consumer demand and significant customer inventory adjustments across all end markets. We are responding decisively to this weak environment by decreasing supply growth through significant cuts to fiscal 2023 capex and by reducing utilization in our fabs. We are confident that the memory industry supply demand balance will be restored as a result of reduced industry supply growth combined with the long-term demand growth drivers for memory.
Micron's technology and manufacturing leadership, deep customer relationships, diverse product portfolio and strong balance sheet put us on a solid footing to navigate this industry downcycle and position the company for strong long-term growth. Our industry-leading 1-alpha DRAM and 176-layer NAND nodes drove strong cost reductions in fiscal 2022. In fiscal Q4, we led the industry again in introducing our 232-layer NAND, becoming the first company to enter volume production on a node with more than 200 layers. We also remain on track to begin the ramp of our 1-beta DRAM node in manufacturing by the end of calendar 2022. Both the 1-beta DRAM node and 232-layer NAND node will provide us with robust cost reduction when they ramp in high volume.
Artificial intelligence, cloud computing, electric vehicles and the ubiquitous connectivity offered by 5G are strong long-term demand drivers for memory and storage. As we have discussed previously, to support memory demand in the second half of the decade and beyond, we will need to add new DRAM wafer capacity. The recently passed CHIPS and Science Act will help to reduce the memory manufacturing cost disparities that exist between the US and Asia. Following passage of the CHIPS Act, Micron announced our intent to invest $40 billion through the end of the decade in leading edge memory manufacturing in the US, contingent on CHIPS Act support. These investments will ultimately create tens of thousands of American jobs, strengthen US supply chain resiliency and further diversify our global fab footprint.
Earlier this month, we announced that we have chosen Boise as one of two leading-edge DRAM manufacturing fab sites that we are planning in the US and we expect to invest approximately $15 billion at the site through the end of the decade. The co-location of this new manufacturing facility with our existing R&D site at our headquarters in Boise, provides multiple strategic benefits, including improving efficiency across both R&D and manufacturing, simplifying technology transfer and reducing time to market for leading-edge products. We will soon announce a second high volume US DRAM manufacturing site. These new fabs will fulfill our requirements for additional wafer capacity starting in the second half of the decade and beyond. We plan to build these sites in stages. Tool installation and production output will be ramped in line with industry demand growth, which is consistent with our goal to maintain stable bit supply share as well as supply discipline.
Now turning to our end markets. Micron's product portfolio has become significantly stronger and contributed to our momentum in the most attractive markets. In fiscal 2022, data center and graphics revenue grew approximately 35% and auto, industrial and networking revenue grew approximately 40%. The combined revenue mix of these important markets grew from approximately 45% of our total revenue in fiscal 2021 to 52% in fiscal 2022, putting us on track to hit our target of 62% by fiscal 2025 as outlined at our Investor Day earlier this year. This portfolio transformation will increase our exposure to the most attractive and stable profit pools in the industry.
In fiscal Q4, data center revenue was down both sequentially and year-over-year, driven primarily by declines in ASP. In fiscal 2022, we set a new revenue record for our cloud revenues, which grew more than 30% year-over-year. Cloud end demand remains healthy, driven by secular growth in AI and the digital economy. However, the data center market, including both cloud and enterprise continues to face some supply constraints that are limiting server builds and customers are reducing memory and storage inventory due to macroeconomic uncertainties. With a diverse set of products across DDR4, DDR5, graphics memory, high bandwidth memory and data center SSDs, Micron offers a wide portfolio of solutions targeting this market with industry leading quality.
Building on our recent momentum of market share gains in data center SSDs, in the first half of calendar 2022, we continue to make solid progress in ongoing qualifications of our 176-layer NVMe data center SSDs at hyperscalers and OEMs around the world.
Fiscal Q4 client revenue was down both sequentially and year-over-year as PC unit and demand declined and customers reduced inventory. We now forecast calendar 2022 PC unit sales to decline by an approximately mid-teens percentage year-over-year. In fiscal Q4 we began ramping 16 gigabit DDR5 in high volume production ahead of anticipated client platform launches. We also commenced volume production of Gen4 QLC NVMe client SSDs and are the only company with a full portfolio of 176-layer TLC and Gen4 QLC NVMe SSDs qualified and shipping to PC OEM.
In fiscal Q4, graphics revenue declined both sequentially and year-over-year. Micron continues to hold an excellent position as a performance leader in the graphics market. In fiscal Q4, we began shipping the industry's fastest graphics memory with 24 gigabit per second GDDR6X, shipping in high volume production. We are excited to see our proprietary GDDR6X memory featured in the recent launch of NVIDIA's GeForce RTX 4090 and 4080 GPUs.
Fiscal Q4 mobile revenue declined both sequentially and year-over-year. Despite the weakness in end unit sales, we achieved two consecutive years of record mobile revenue in fiscal 2021 and 2022. We now project calendar 2022 smartphone unit volume to decline by a high single-digit percentage year-over-year. 5G continues to drive greater content per device and we project 5G penetration to exceed 50% of the smartphone unit TAM in calendar 2022. We continue to execute well on our mobile product roadmap. In fiscal Q4 1-alpha comprised over 70% of our LPDRAM mobile bit shipments and 176-layer made up approximately 95% of our mobile NAND bit shipments.
Micron is exceptionally well positioned as the leader in automotive and industrial markets which are attractive because of strong long-term growth and relatively stable margins. In fiscal Q4, our automotive business delivered another record revenue quarter and fiscal 2022 auto revenues grew 30% year-over-year, setting a new all-time high. In fiscal Q1, we see some slowdown in our automotive demand as our customers rebalance DRAM and NAND inventory levels as they deal with non-memory semiconductor shortages and production challenges. However, we see continued strong growth in our second half of fiscal 2023, with volume ramp of advanced next-generation in-vehicle infotainment systems as well as the broader adoption of more advanced driver-assistance systems. We are extremely excited by the long-term prospects for memory and storage in the automotive market and expect long-term CAGR for DRAM and NAND in autos to be at about twice the rate of the overall DRAM and NAND markets.
While long-term fundamentals remain strong, our industrial IoT business saw sequential and year-over-year revenue declines in fiscal Q4. Softening macroeconomic conditions have led some customers to reduce overall purchases of DRAM and NAND. Nevertheless, our long-term outlook remains strong for our industrial business, driven by the proliferation of factory automation and digitization.
Turning to the market outlook. The memory and storage industry environment has deteriorated sharply since our last earnings call. Calendar 2022 industry bit demand growth for DRAM is now expected to be in the low-to-mid single-digit percentage range, and for NAND, slightly higher than 10%. An unprecedented confluence of events has affected overall demand, including COVID-related lockdowns in China, the Ukraine war, the inflationary environment impacting consumer spending, and the macroeconomic environment influencing customers' buying behavior in multiple segments. In addition, inventory adjustments at customers across all end markets are also contributing to demand weakness. These factors are depressing demand for DRAM and NAND to well below end market consumption levels. We are also seeing an extremely aggressive pricing environment. Due to the sharp decline in near-term demand, we expect supply growth to be significantly above demand growth in calendar 2022, contributing to very high supplier inventories for both DRAM and NAND.
Looking ahead in calendar 2023, while macroeconomic uncertainty is high and visibility is low, we currently expect demand growth to be closer to the long-term growth rates of both DRAM and NAND, bouncing back from very weak levels in calendar 2022. We expect the inventory at our customers to improve in early calendar 2023, causing demand to rebound starting from the second quarter of calendar 2023. We expect calendar 2023 industry DRAM supply to grow well below demand growth. We are modeling a mid-single-digit percentage growth in DRAM industry supply in 2023, which would represent the lowest-ever industry supply growth. NAND supply growth in calendar 2023 is also expected to fall below demand growth. Given the elevated supplier inventories entering calendar 2023, we expect industry profitability to remain challenging in 2023. Following a weak first half of fiscal 2023, we expect strong revenue growth in the second half of fiscal 2023 as bit demand rebounds, following substantial improvement in customer inventories.
Projections for long-term demand trends remain strong across multiple end markets. We expect long-term DRAM bit growth to be in the mid-teens percentage, slightly lower than our prior expectation of mid-to-high teens due to a moderation in expectation of long-term PC unit sales. We continue to expect the NAND market, which benefits from elasticity, to grow around 28% over the long-term.
Turning to our supply. Given the change in market conditions, we have been taking immediate action to reduce our supply growth trajectory and align it to market demand. We made significant reductions to capex and now expect fiscal 2023 capex to be around $8 billion, down more than 30% year-over-year. Capex would be lower if it were not for more than doubling our construction capex year-over-year to support the supply growth required to meet demand for the second half of this decade as well as investment for EUV lithography systems to support 1-gamma node development. WFE capex will decline nearly 50% year-over-year and reflects a much slower ramp of our 1-beta DRAM and 232-layer NAND versus prior expectations. Fiscal 2023, WFE capex is focused on developing the technology capability of our leading nodes and new product introduction. To immediately address our inventory situation and reduce supply growth, we are reducing utilization in select areas in both DRAM and NAND.
Our capex and utilization actions will have an adverse impact on our fiscal 2023 costs, but they are necessary to bring our supply and inventory closer to industry demand. We will aim to grow our DRAM and NAND supply in line with demand over time, while continuing to optimize our costs and portfolio to improve our profitability.
Before passing it over to Mark, I want to reflect on the tremendous progress that the Micron team has made over the last few years. Today we are the technology leader in both DRAM and NAND, with a very competitive cost structure. We have leadership products and a strong portfolio that is transitioning toward high-value solutions, and we are gaining share in products that represent a more attractive profit pool in our industry.
Our balance sheet is strong and allows us to invest appropriately to maintain technology, product and manufacturing leadership going forward. Our world-class quality and manufacturing expertise is recognized by our customers worldwide. We have delivered record revenues in multiple end markets in fiscal 2022 while returning record levels of cash to our shareholders. While the near-term environment is challenging, we are confident in our ability to emerge stronger and deliver financial performance in line with our long-term financial model. The long-term manufacturing investments we are making will further strengthen our diversified fab footprint and position us to capitalize on the exciting long-term opportunities ahead of us.
I will now turn it over to Mark.
