Micron reported Q2 results that beat estimates and guided for Q3 sales and earnings growth above expectations. However, Micron’s share are off 9% post-earnings, which may be due to commentary around soft demand in China, slowing PC sales and concerns that Micron may be nearing the top of the cycle. We believe that these concerns are temporary, and that Micron is structurally becoming a less cyclical company, which deserves a premium multiple. I discuss the company’s latest results and why we believe the recent sell-off is overdone in more detail below.
Micron’s Q2 FY2022 Beat Expectations and Guidance Was Above Consensus
Micron reported Q2 FY2022 results on March 30th, and sales increased 1% QoQ to $7.8 billion driven by a 4% sequential rise in NAND sales, which accounted for ~25% of total revenues. NAND sales also increased 19% YoY and management expects NAND sales to increase by ~30% YoY for the year. Demand for NAND is being driven by Micron’s new 176-layer NAND technology, which represented the majority of Micron’s NAND shipments. We explained the importance of 176-layer NAND here, stating that Micron has significantly increased memory capacity and is a leader in this technology, allowing the company to capture more market share.
Importantly, the strength in NAND should also be a tailwind for Lam Research, which sells the etching equipment necessary to build the layers for 176-layer NAND. In our latest update on Lam Research, we explained that “the key reason we think Lam could fare better than its peers is because as 3D layers increase, capital intensity also increases. The process does not scale linearly, instead it’s non-linear because it takes longer than 2X to etch a stack that is 2X high and requires more complex etch and deposition equipment”. With Micron guiding for $12 billion in Capex this year and plans for $150 billion in capacity expansions over time, we should expect Lam Research to see strong demand for etching equipment going forward.
Micron’s NAND prices also benefitted from the contamination of ~8% of the global supply of NAND. In February, memory peer Western Digital disclosed that there was a contamination event at two of its Japanese JV facilities, which resulted in 6.5 exabytes of NAND memory being contaminated. Likely benefitting from this event, Micron’s Q2 NAND prices rose ~4% QoQ, driving much of the topline growth as volumes were flat. As shown below, Micron has outperformed relative to Western Digital YTD, however, both companies have underperformed the broader market in 2022. I outline a few reasons for this in more detail below, which we believe are only temporary.
Similar to NAND, DRAM sales increased 2% QoQ and were up 29% YoY to $6 billion, or 73% of total sales. DRAM volumes increased but were offset with a decline in ASPs. Strong demand in datacenter drove the increase in DRAM sales. For example, Micron’s largest segment, Compute and Networking, grew sales 31% YoY to $4 billion, driven by a 60% YoY rise in data center sales which were “supported by robust demand across our DRAM and SSD portfolio” (Q2 call, 03/30/22). DRAM sales benefitted from Micron’s leading 1-alpha technology which is increasingly being adopted in the memory-intensive cloud environment. During the Q2 call, CEO Sanjay Mehrotra stated that DRAM sales will continue to ramp into 2023 when he said that “We have broadened the qualifications for our 1-alpha DRAM products and are well positioned to support the data center DDR5 transition driven by new CPU platforms, which are targeted to begin ramping later this calendar year and gain momentum in 2023”.
Following the strength in cloud sales, Storage sales increased 38% YoY to $1 billion as SSDs continue to replace HDDs, while Embedded sales increased 37% YoY driven by strength in automotive. A blemish was weakness in Mobile sales, which increased just 4% YoY to $1.9 billion. While the rollout of 5G phones will lead to a ramp in memory content per phone, there may be demand headwinds on the horizon. For instance, Apple cut its forecast of 5G iPhone shipments by ~20%. I discuss this in more detail below.
Continuing down the income statement, gross margin increased by 2,100 bps YoY and 100 bps QoQ to 47%, benefitting from higher NAND margins and the ramp in 1-alpha DRAM and 176-layer NAND technologies, which reduces costs as it scales. Management noted on the Q2 call that most of the efficiency benefits have been realized, and that margin expansion from the ramp is largely behind the firm. Furthermore, YoY gross margin comps were impacted by a one-time $300 million charge taken last year when Micron switched to FIFO accounting.
The strength in gross margin flowed down to operating profit, which increased 118% YoY to $2.7 billion. The dramatic rise in profitability was driven by higher selling prices and cost reductions from the ramp in new technologies outlined above. However, Micron has historically been a cyclical industry, and there may be concerns that Micron is nearing the top of the cycle. This may explain the recent sell-off in Micron’s sales, yet we believe that Micron is becoming structurally less cyclical and that its multiple will rebound once this is clearly evident in future results (discussed in more detail below).
Finally, GAAP earnings per share were $2.00 while non-GAAP EPS was $2.14, which beat estimates by $0.16. Non-GAAP EPS increased 118% YoY and the strength in EPS growth should continue going forward. For instance, Micron will benefit from a lower tax as Idaho’s governor signed a new tax law on March 16th, 2022 that will reduce Micron’s taxable income (Micron is HQ in Idaho). The CHIPS act may also be a tailwind to earnings as the US government looks to incentivize reshoring of manufacturing capacity.
As of the end of the quarter, Micron had $12 billion in cash and equivalents and free cash flow was over $1 billion during the quarter. Management stated that they expect free cash flow generation will be “substantially higher” over the next two quarters relative to H1 2022. Micron intends to use ~50% of its free cash flow to buy back its stock and pay dividends to shareholders. Since 2019, Micron has reduced its share count by an aggregate 113 million, or by 9%. With Micron guiding for record sales and profits in FY2022, cashflow generation should be significant, which will support more buybacks in the future.
Looking forward, management expects Q3 sales to grow 18% YoY to $8.7 billion, which beat initial topline estimates by 6%. Management stated that they are “tracking ahead” of their initial guide set in Q1 for FY2022 and that demand remains strong, but noted during the Q2 call that “there are some pockets where semiconductor shortages have not improved as fast as we had expected, and these shortages are likely to continue into calendar year 2023”. Nonetheless, Q3 adjusted EPS is expected to grow 14% QoQ to $2.46, which beat initial estimates by 9%.
Potential Risks are only temporary
As discussed above, Micron reported strong top and bottom-line results, guided above consensus and expects to be report record sales and earnings in FY2022. However, despite this, Micron has underperformed in 2022 and is off ~9% since announcing FQ2 results. This may be due to a couple developments: 1) softness in mobile and PC sales and in China, 2) and concerns that Micron may be nearing the top of the cycle.
In regards to the first point, during the Q2 call management stated that “We see some weakness in the China market as the local economy slows, smartphone market share shifts and some customers take a more prudent approach to inventory management.” CEO Mehrotra added that he expects PC unit growth will be “flattish”. These comments may have contributed to a post-ER sell-off, and it is notable that AMD is also off following the Micron Q2 print, likely due to its exposure to PC sales. However, management added further color that enterprise PC sales are expected to be strong in the near term, which are more content rich in terms of DRAM and NAND content, which should offset this pressure.
Moreover, 5G phone sales are just now starting to ramp, but the timing of this ramp remains unknown. As mentioned above, Apple has reportedly cut its production forecasts for its first 5G phone by ~20%. While this may be a near-term headwind, it is inconsequential in the long term. This is because 5G phones will inevitably take share from 4G going forward, and 5G phone DRAM content is 50% higher than 4G, while NAND content is >100%.We expect mobile will be a tailwind going forward, despite the near term uncertainty in the pace of the ramp.
Finally, a trend that is typical with highly cyclical companies is that investors tend to reduce exposure when earnings are high due to concerns that the company may be nearing the top of the cycle. Historically, Micron has been a highly cyclical company with periods of oversupply and rapidly declining prices. However, with more demand drivers coming from data centers/cloud and automotive, memory demand is no longer dependent on the short-cycle PC market.
During the Q2 call, CEO Mehrotra explained that over 75% of its quarterly volume are under long-term agreements (LTA) that go out beyond four quarters or more, up from less than 25% in prior years. CEO Mehrotra added that all of the company’s large customers are now under LTAs, which helps improve demand visibility and reduces uncertainty. An increase in LTAs significantly reduces the cyclicality of Micron’s business.
Moreover, new trends on the horizon further smooth demand for memory, reducing Micron’s dependence on the short-cycle PC market. For example, CEO Mehrotra stated that “new EVs are becoming like data center on wheels, and we expect over 100 new EV models to launch worldwide in this calendar year alone”. The memory content in higher end EVs is 15x higher than the average car, which further reduces the cyclical nature of Micron’s business.
As shown below, Micron trades at a 9x PE multiple, which is below where it was trading in 2017 and well below its multiple in 2020 and 2021. We believe that the market remains in a “wait and see” mode until Micron can prove that it is less cyclical. If Micron can prove that it is less cyclical going forward, we should expect a re-rating of its multiple going forward. A trend that supports this is the reduction in finished goods, which declined QoQ despite the softness in China, PC and mobile. A build in finished goods inventory would signal that demand may be weakening, a trend we have yet to observe in the memory market.

Overview of Micron’s Products:
By Beth Kindig
When we first covered Micron, the company’s revenue was two-thirds DRAM and one-third NAND. The company’s most recent earnings report shows a heavier weight on DRAM at three-quarters revenue compared to one-quarter revenue from NAND.
NAND memory saves data even when the power is removed, such as when a cell phone is turned off. Beyond mobile devices, NAND is found in traffic lights, digital advertising panels/displays, and anything with artificial intelligence that needs to store data.
Dynamic RAM, or DRAM, stores memory when a device is on, such as PC processors and graphics cards. DRAM is also used in gaming devices and video game consoles. DRAM is 100X faster than NAND, lasts longer, and is smaller in size. However, DRAM is known as volatile memory which means when power is turned off, it does not store data. The benefit of loading the data into the RAM is that reading the data is much faster than reading it from the hard drive.
According to the CEO of Micron, AI servers will require six times more DRAM and twice the SSDs compared with standard servers. In the most recent earnings report, it was also pointed out that “DRAM and NAND stem share of the semiconductor industry has steadily grown over the last two decades, from around 10% to approximately 30% today.” Today, data centers are the largest market for memory and storage due to the growth driven by cloud.
Hyperscale data centers are growing faster than DRAM supply can keep up with. Due to higher capacities and low latencies, DRAM is being used across health care, the military, automotive, networking systems, and data centers. DRAM is being used in the Internet of Things (IoT) due to low latency with automotive using up to 80GB compared to 5.5GB in PCs and 2.5GB in handsets.
NAND is used to store pictures or music on a mobile device and is also particularly well suited for edge devices because it’s ideal for high data storage density. Although DRAM drives the majority of Micron’s revenue right now, NAND is the growth segment to watch as AI workloads move to the edge and will require NAND for the increased energy requirements, portability, and ability to store massive amounts of data.
According to FiorMarkets, Global 3D NAND Flash is expected to grow at a 32.3% CAGR from 2019 to 2025. 360 Research Reports put the CAGR at 20.6% between 2021-2026. Overall, NAND is expected to grow at 11.05% between 2021-2026. DRAM has a CAGR of 7% between 2020 and 2026.
Micron’s revenue segments
By business unit, Micron saw the most revenue growth from Embedded (EBU) at 108% year-over-year and 23% QoQ growth. This was also the largest growth in the prior year. EBU refers to memory and storage products used in automotive, consumer markets, and industrial applications. In 2019, Micron had expanded its wafer fab facility in Virginia with a $3 billion investment to manufacture 20nm/1xnm DRAM and 3D NAND for automotive infotainment, advanced driver-assistance systems (ADAS), and also industrial automation and surveillance applications. Two years later, the investment and engineering expansion appears to be paying off.
This is a key segment to watch as industry CAGR for automotive processors is expected to be 65% through 2023, according to IDC. This is driven by automation and the memory content per car will increase up to 16GB of DRAM and 1TB of NAND to run AI, supercomputer, and high-def mapping. Micron holds 48% of automotive memory market share and is the primary supplier to Nvidia and Intel.
Compute and Networking (CNBU) grew at 26% growth year-over-year and 15% quarter-over-quarter. This is the segment that serves cloud servers and PCs, plus graphics and networking markets, and this segment is the largest source of revenue and operating income for Micron. Bradley expands more on this in his write-up below.
Mobile Business Unit (MBU) focuses on mobile and smartphones and mobile saw its highest-ever mobile revenue in fiscal year 2021. This is partly driven by the uMCP5 multichip package which allows smartphones to handle data-intensive 5G workloads. Micron has also released low-power DRAM for edge devices in a promotion with MediaTek. Micron offers a combined chip for both NAND flash storage and DRAM for 5G smartphones to extend battery life and increase performance without taking up circuit board space. This segment is also one to watch as the memory in smartphones will increase exponentially with 5G due to large data volumes.
Micron has exposure to PCs. This has been a boon during the past few years yet could also weigh on Micron if consumer spending slows.
3D NAND product update
Last year, Micron released a 176-layer 3D NAND product that has a layer count 40% higher than the nearest competitor, which is Samsung. The new NAND device is 10 times denser than previous 3D NAND devices which allows smartphones and edge devices with capacity limitations removed and increased power efficiency. Cloud storage also benefits due to being data intensive.
According to Micron, this device has the “industry’s highest data transfer rate” of 1,600 megatransfers per second (MT/s). The device is the same height as the 64-layer design with a fabrication technique that removes stack height limitations to provide higher storage capacities. The company uses CMOS-under-array (CuA) to build a multi-layered cell stack for more memory to be leveraged in a smaller space while also decreasing die size.
The replacement-gate (RG) flash technology replaces the traditional floating-gate design, and according to Micron’s whitepaper, helps the device remain competitive in terms of time it takes to program and/or to limit the reduction in performance. Micron points out in the paper that extending the number of tiered stacks creates cell-to-cell capacitive coupling, which leads to lower program times. Therefore, the more tiers or layers that competitors release will not necessarily result in better performance due to design limitations. This performance becomes critical as program algorithms can add to time delays when writing the data.
In this iteration, Micron changed the design to mitigate issues of the “cell-to-cell capacitance structure,” or a reduction of electric field duration and increase in voltage threshold (VT), which results in higher endurance life span, increased power efficiency, increased storage capacity, and doubled speed of write performance. The company also changed the material from polysilicon to metal. These two improvements result in Micron’s RG 3D NAND to perform up to 2X faster than other current 3D NAND devices.
Memory and storage can be very competitive in terms of price, so we want to track incremental product improvements. According to Micron, “current 3D NAND design has begun to reach the limits of its monolithic die-level maximum capacity. It will continue to fall short of the immense system-level storage capacities demanded by future data-driven applications. Cell-to-cell capacitive coupling complications and smaller etch requirements account for many of these limitations.” If Micron is correct, then this could be an opportunity for the company to see more market share on 3D NAND.
NAND is expected to see a 30.8% increase in total bit demand and an oversupply in the second half of next year. Competition is expected to drive a decrease in average sales price (ASP). In the earnings presentation, Micron forecast calendar year 2022 growth of 30% in NAND.
DRAM product update
Moore’s Law states that the number of transistors or processing power on an integrated circuit doubles every two years while the cost is halved. This has led to shrinking the circuits to fit more transistors or memory cells in the limited space. At one point, you could see a transistor and now they are measured in nanometers, which is not visible by the human eye. This helps chips switch faster and use less energy and are cheaper to make, as well. As size decreased, memory chips moved to the Roman and Greek alphabet to name nodes which is why Micron calls their DRAM “1-alpha.’ This provides a 40% improvement over bit density compared to the 1z node and power consumption has improved by up to “20 percent.”
These chips are manufactured without EUV, or Extreme Ultraviolet Lithography. This manufacturing method uses smaller 13.5nm wavelengths of ultraviolet light to etch wafers as opposed to lasers from Deep Ultraviolet Lithography (DUV). You could argue that EUV is a point of weakness for Micron as Samsung is using this manufacturing method while Micron is delayed until 2024.
DDR5 is the company’s increased bandwidth product that will increase core count resulting in up to 85% increase in bandwidth. The double date rate (DDR) product has been primarily focused on more bandwidth while previous generations focused on reducing power consumption to serve the needs of mobile applications and data centers. The performance increase is between 1.36X and 1.87X. This has not been released yet but is expected to be released soon.
DRAM is expected to see a decrease in average sales price (ASP) next year while DRAM bit demand will increase by 17%. This will lead to an oversupply in the second half of the year. Micron is forecasting DRAM revenue to be in the mid-to-high teens.
Being U.S. based, plus MU, lowered exposure to China
It’s very helpful that Micron is the only U.S. based manufacturer of memory during a time when suppliers are relocating to the United States. Micron announced that it intends to invest $150 billion globally over the next decade in “leading-edge memory manufacturing and research and development (R&D) including potential U.S. fab expansion.” The U.S. Senate passed the U.S. Innovation and Competition Act (USICA) which includes $52 billion in federal investments for the domestic semiconductor research, design and manufacturing provisions in the CHIPS Act. Congress is also considering legislation called the FABS Act that would establish a semiconductor investment tax credit. Policy could strategically help Micron compete with Samsung.
The next hurdle for semis long-term is relying on China sales. Micron changed how they report geographic information from ship-to location to customers headquarters. Micron also lost Huawei revenue during the same time period which Keybanc estimates was 7-9% of Micron’s revenue.
Here's a snapshot from fiscal Q4 2018 where “ship-to location” was heavily weighted to China.
If we go on customer headquarters then we see that Micron has about 18% exposure in FY2021 if we include China and Hong Kong.
Competitors
Micron was the first to build and ship a 176-layer NAND last year and SK Hynix was close behind. In early 2020, Kioxia and Western Digital released a 112-layer device and are expected to move to 160-layer soon based on split-gate architecture by stacking two 80-layer structures. By splitting the gates, the cell size is reduced in half and this increase the capacity. YMTC was a new competitor from China that released a 128-layer very quickly by skipping the 96-layer generation. The company uses an expensive copper hybrid bonding technique that enables higher bit density. YMTC is likely to take market share in China across all memory and storage competitors.
According to TrendForce, SK Hynix saw the largest increase QoQ on NAND flash sales with a 25% QoQ increase and Kioxia reported 3D NAND sales of 20.8% QoQ compared to Micron’s 8% increase QoQ. In terms of DRAM, TrendForce reported that Samsung grew it’s lead with 11% growth QoQ while Micron also grew it’s lead with 12% growth QoQ compared to SK Hynix at 8% QoQ.
Micron is Becoming Less Cyclical
By Bradley Cipriano
Micron has reported strong results over the last few years and this continued into 2021. Micron is a key player in the memory market, which is going through a structural change. Demand is no longer dependent on PCs, rather memory demand is now being driven by much stronger tailwinds such as datacenter server growth and the rollout of 5G. This structural change is making Micron less cyclical.
Looking forward, Micron expects these structural tailwinds to continue to drive growth at the company. CEO Sanjay Mehrotra explained it well during the Q4 FY2021 Conference Call when he said that “Industry trends like the broad integration of artificial intelligence into all computing, proliferation of the intelligent edge, continued data center growth, and deployments of 5G networks create new and expanding opportunities for Micron.”
The rise of cloud data centers has led to a structural increase in demand for semiconductor components such as DRAM and NAND memory, which helps smooth out the boom and busts cycles that Micron was historically exposed to. Micron explained the new market dynamic in its 10K when it stated that “data is today’s new business currency, and memory and storage are a critical foundation for the data economy”.
The IDC estimates data creation will explode going forward (pictured below), driven by the rise of cloud computing. Furthermore, the IDC estimates that less than 2% of data is saved today, and that data creation is far outpacing data storage capacities.
Furthermore, the ramp of the metaverse also requires massive scaling. During Marvel’s (MRVL) Q3 Conference Call, the company stated that the metaverse “will significantly accelerate a number of key trends, which are already occurring in the cloud today, including the need to store huge amounts of data”. With Meta (aka Facebook) guiding for $34 billion in capex in 2022 to develop the metaverse, the demand for data storage will likely be strong for the foreseeable future.
We can see the structural change underway by looking at results over the last four years. For instance, aggregate gross margin over the last four years was 44%, well above historical (cyclical) periods, and aggregate operating cashflow margin was ~50% over the same time period. In response to the structural change underway in the memory market, management recently initiated a quarterly dividend ($0.10 per share), which highlights management’s contention that the memory market is becoming less cyclical. I discuss Micron’s recent financial results in more detail below.
New memory technologies keep pace with cloud innovation
To address the issue of exploding data creation, Micron has innovated on some key new technologies that will enable datacenters to capture and retain much more data. Two of these key new technologies are 176-layer NAND and 1-alpha DRAM, which Micron began shipping in volume this year.
Micron stated that the introduction of “176-layer NAND and 1α (1-alpha) DRAM represent major technology breakthroughs for our company and the first time in our history that we have achieved industry leadership across these two flagship technologies”. 176-layer NAND is an extension of 3D NAND, and as the name implies, has 176 layers of cells that dramatically increase memory capacity. Previously, NAND was on a 2D plane with just one layer, and Micron has significantly increased capacity by expanding beyond a single layer of memory. Furthermore, the 1α DRAM memory node was introduced in 2021 and materially improves the performance of DRAM memory (20% to 30% higher yields), which is critical for cloud servers that rely on low latency and high performance.
With the continued development of AI, cloud servers require significantly higher quantities of DRAM, as the number and capabilities of these intelligent edge devices increases, more data is stored, processed and accessed in the cloud. The demand for storage in the cloud environment is growing exponentially and Micron’s industry leading 1α DRAM nodes should be able to capture market share in this fast growing segment in FY2022. We can see the strength in cloud computing by looking at Micron’s Compute and Networking segment (CNBU) sales, which increased 34% YoY to $12.3 billion during FY2021 and rebounded from an 8% YoY decline in the prior year.
CNBU is Micron’s largest segment (44% of sales) and continued strength here will be rewarded by the market. With that said, there was a deceleration in this segment between fiscal Q3 and fiscal Q4 both YoY and QoQ from 49% down to 26% YoY growth and down from 25% to 15% on QoQ growth.
In Q2 FY2021, Micron also began shipping 1α DRAM nodes for mobile, which improved power efficiency in mobile phones, and allows for memory intense use cases like smart photography. Management explained on the Q4 call that 5G phones have 50% more DRAM than 4G phones, meaning that the continued adoption of 5G phones should be a significant tailwind for Micron going forward.
Micron also began volume shipments of 176-layer NAND for mobile in 2021. On the Q4 call, CEO Mehrotra explained that “176-layer NAND-based mobile product went from just introduction to 1-million-unit shipments in a record time. Fastest RAM in the history of the Company”. The ramp in 176-layer NAND helps put into perspective how much demand there is for Micron’s new technologies. Following this strong demand, Mobile (MBU) segment sales increased 26% YoY to $7.2 billion in FY2021, a record high. The continued roll-out of 5G phones will likely be a tailwind for Micron going forward.
The roll out of these new technologies is just now beginning to ramp. To accelerate the roll out of these new technologies, Micron expects to increase its annual capex by 20% YoY to $12 billion, which follows a 22% YoY rise in capex in FY2021. Micron explained that capex will be driven by its continued transition to 176-NAND, as well as infrastructure support for the introduction of new technologies such as EUV lithography. While increased capex spend does not guarantee increased sales, there are also signs in Micron’s balance sheet that point to heightened demand in the near term, which I discuss in more detail next.
Micron’s financials
Following the roll out of new technologies during the year, Micron reported strong results to end its fiscal year. Specifically, Micron’s Q4 FY2021 sales increased 37% YoY to $8 billion, an acceleration from the 36%, 30%, and 12% YoY increase in Q3, Q2, Q1 respectively. Gross margin increased 1,300 bps YoY to 47%, the highest level since Q3 FY2019. On a rolling four-year basis, gross margin was 44%, highlighting the strong success Micron has experienced in recent years. As shown below, the sustained improvement in four-year rolling gross margin suggests that Micron’s business is becoming less cyclical.
The strong gross margin flowed down into operating margin, which increased 1,600 bps YoY to 36%. On an annual basis, operating margin improved from 14% in FY2020 to 23% in FY2021, while non-GAAP operating margin was 28%, up 1,200 bps YoY. The strong margin performance was driven by pricing increases across DRAM and NAND products and ongoing product transformation. Looking forward, management guided that gross margin would remain strong at 47% +/- 100 bps in Q1 FY2022, as the company continues to benefit from the new product releases (discussed in more detail above).
Continuing down the income statement, GAAP EPS increased 175% YoY to $2.39 and on an annual basis GAAP EPS increased 117% YoY to $5.14. In the last five years, Micron has reported an aggregate $28.94 in GAAP EPS, or nearly five times as much as it had earned in aggregate earnings over the prior 33 years (dating back to 1984). As discussed above, Micron had historically been a cyclical company dependent on PC demand for memory, but tailwinds from datacenter and mobile have structurally changed the demand environment for memory and have made Micron’s business less cyclical and more profitable. Below, we look at the 4-year rolling gross margin to discuss the continued strength in the company.
We can also see this outperformance in cashflows. Micron’s annual cashflow margin was robust at 45%, and FCF margin was also strong at 9%. Annual FCF margin has been positive in all but one year since 2012 and has been positive for five consecutive years. As a result of the strong cashflow performance over the last few years, management initiated a quarterly $0.10 dividend.
CFO Dave Zinsner stated on the Q4 call that “the initiation of a dividend is an important milestone that reflects the structural transformation Micron has undergone over the last several years, and it shows our confidence in the sustainability of our cash flow generation”. He added that Micron expects to return more than 50% of FCF to shareholders through dividends and buybacks going forward. If the memory business is becoming less cyclical, then shareholder returns could be substantial going forward given Micron’s robust profitability and cashflow generation.
Finally, inventory trends also highlight the strong demand for Micron’s products. Inventory declined 17% YoY despite the 37% YoY growth in sales, as Micron has struggled to replenish lean inventory levels in response to strong customer demand. Typically, in cyclical industries, elevated inventory levels can be a sign of concern, so the drawdown in inventory highlights the strong demand for memory in the current environment.
Inventory composition is also bullish, as raw material inventory increased to 11% of total inventory, a three-year seasonal high, while finished goods inventory declined from 19% of inventory to 11% in Q4, a five-year low. The drawdown in finished goods highlights that Micron is shipping its product faster than it can be replaced, highlighting the strong demand it is experiencing. A rise in raw materials and decline in finished goods means that management is quickly selling its product and anticipates that this demand will continue.
Outlook and valuation
However, a risk with the low inventory levels is that Micron will not be able to fulfill the strong demand in the near term. There are also supply chain issues outside of Micron’s control that may impact demand in the near term. CEO Mehrotra explained on the Q4 call that some PC customers are adjusting memory purchases in the near term due to non-memory component shortages. He added that supply chain constraints for IC components will limit some large shipments in the near term.
This commentary helps explain Micron’s Q1 FY2022 forward guide miss. Micron guided Q1 sales to be $7.65 billion at the mid-point, 10% below the Street’s initial estimate at $8.5 billion. Micron also guided Q1 EPS to be $2.10 at the midpoint, or 15% below initial expectations of $2.48. CEO Mehrotra explained that while there are near term supply chain issues, “shipping growth will resume in the second half of the fiscal year, and we're planning to deliver record revenue with solid profitability in fiscal 2022”. While Micron only quantified its Q1 guide, CEO Mehrotra’s statements suggest that growth will rebound in the second half of the year as supply chain issues and low inventory levels normalize.
Looking forward, Micron is expected to report Q1 earnings on December 20th. Q1 sales are expected to increase 33% YoY to $7.65 billion and non-GAAP EPS is expected to rise 169% YoY to $2.10. For the year, Micron is expected to grow sales 16% YoY to $2 billion and to report $9.01 in non-GAAP EPS, which gives it a 9.2x fwd EPS multiple. This is slightly below Intel’s fwd P/E multiple of 9.7 but above Western Digital’s fwd P/E of 6.7x. Furthermore, Micron’s fwd P/E of 9.2x is below the 15.8x level it reached earlier in the year, which highlights that there is room for multiple expansion going forward.
Micron also trades at a slight premium based on trailing earnings. Its TTM P/E multiple of 16x is 45% higher than the peer median of 11x (peers include Samsung, SK Hynix, Intel, and Western Digital). Micron is likely being awarded a premium over its peers due to its current technological lead in key technologies discussed above.
Conclusion
Micron’s sales grew 29% YoY in FY2021 and management expects this growth to continue into FY2022 as demand for memory remains robust. The memory market is becoming less cyclical due to numerous tailwinds that have expanded demand for memory beyond PCs and into more memory intensive markets such as data centers and mobile. Micron is ramping capex to keep pace with outsized demand and has innovated new technologies to keep pace with the cloud environment.
Management also issued a quarterly $0.10 dividend, which further highlights management’s contention that its market is becoming less cyclical. Micron currently trades at 9x fwd P/E, which is near Intel’s and above Western Digital’s multiple. If the company can prove to the market that its business is less cyclical and that its 40% gross margin and 50% cashflow margins are sustainable, then its multiple will likely expand going forward.
