  • EPS (non-GAAP): $1.45 vs analyst estimates of $1.37 (5.82% beat)
  • Revenue guidance for Q1 2023 is $4.25 billion at the midpoint, below analyst estimates of $5.68 billion
  • Free cash flow of $196 million, down 85% from previous quarter

  • Gross Margin (GAAP): 39.4%, down from 47.8% same quarter last year

Founded in the basement of a Boise, Idaho dental office in 1978, Micron (NYSE:MU) is a leading provider of memory chips used in thousands of devices across mobile, data centers, industrial, consumer, and automotive markets.

Micron is one of the leading producers of both DRAM and NAND memory chips globally, though DRAM has consistently accounted for the majority of Micron’s revenues. Micron’s DRAM is mostly used in PCs, servers, networking gear, along with industrial and automotive verticals. NAND is used in the same end markets, along with a heavy weighting in consumer devices like smartphones and tablets. Memory has the most volatile pricing dynamics in the semiconductors industry, which can result in Micron’s earnings results fluctuating wildly. As a result Micron’s valuation will often appear abnormally low compared to other semiconductors during the peak of the memory cycle, with the stock often trading for low to mid single digit forward earnings multiples (4x-8x) before dramatically expanding to high teens to mid twenties (18x-24x) when the cycle turns down.

Micron’s peers and competitors include Western Digital (NASDAQ:WDC), Seagate (NASDAQ:STX), SK Hynix (KOSI:000660), and Samsung (KOSI:005930).

Memory Semiconductors

The global memory chip market has become concentrated due to the highly commoditized nature of these semiconductors. Despite the market consolidation, DRAM and NAND are subject to wide pricing swings as supply and demand ebbs and flows. This plays itself out in the business models of memory producers, where the large, fixed cost bases required to produce memory chips in volume can become very profitable during times of rising prices due to high demand and tight supply but also can result in periods of low profitability when more supply is brought online or demand drops. Read More There are two main types of memory chips: dynamic random access memory (DRAM) and Flash memory (NAND). In any electronic device where a processor or a graphics chip is conducting a task using data, it needs to read the data from where it is stored, known as memory. Smartphones, PCs, and data centers account for more than two thirds of memory demand. DRAM is “volatile” memory, it is a semiconductor that requires an electric charge to retain data – it is the type of memory commonly used in PCs. The advantages of DRAM are the speed at which a CPU/GPU can access the data and its long useful life. Unfortunately, “volatile” means it only can hold data temporarily when it is powered. By comparison, flash memory or NAND is “non-volatile” memory, which means that it saves data when power is removed, making it commonly used in almost every mobile device, along with USB flash drives. Its smaller form factor and greater storage capacity has made NAND-powered solid state drives (SSDs) the long term replacement for the original computing storage device, the hard disk drive.

Sales Growth

Micron Technology's revenue growth over the last three years has been unremarkable, averaging 12.9% annually. Last year the quarterly revenue declined from $8.27 billion to $6.64 billion. Semiconductors are a cyclical industry and long-term investors should be prepared for periods of high growth, followed by periods of revenue contractions (which can sometimes offer opportune times to buy).

Micron Technology Total Revenue

It was a difficult quarter for Micron Technology, with revenue declining by 19.8%, missing analyst estimates by 1.96%. Micron Technology's growth turned to declines this quarter, signaling that the current downcycle is deepening.

Revenue growth went from positive to negative this quarter, and Micron Technology expects it to stay negative next quarter with an estimated decline of 44.8% YoY and analysts think the declines will continue, with next twelve months estimated at 20.3% declines.

Product Demand & Outstanding Inventory

Days Inventory Outstanding (DIO) are an important metric for chipmakers, as it reflects the capital intensity of the business and the cyclical nature of semiconductor supply and demand. In a tight supply environment, inventories tend to be stable, allowing chipmakers to exert pricing power. Steadily increasing DIO can be a warning sign that demand is weak, and if inventories continue to rise the company may have to downsize production.

Micron Technology Inventory Days Outstanding

This quarter, Micron Technology’s inventory days came in at 151, 35 days above the five year average, suggesting that that inventory has grown to higher levels than what we used to see in the past.

Pricing Power

Micron Technology's gross profit margin, how much the company gets to keep after paying the costs of manufacturing its products, came in at 39.4% in Q4, down 8.4 percentage points year on year.

Micron Technology Gross Margin (GAAP)

Micron Technology' gross margins have been trending up over the last year, averaging 44.9%. This is around the average of what we typically see in semiconductor businesses, but the rising margin may be indicative of improving cost controls.


Micron Technology reported an operating margin of 25% in Q4, down 12.1 percentage points year on year. Operating margins are one of the best measures of profitability, telling us how much the company gets to keep after paying the costs of manufacturing the product, selling and marketing it and most importantly, keeping products relevant through research and development spending.

Micron Technology Adjusted Operating Margin

Operating margins have been trending up over the last year, averaging 33%. Micron Technology's margins remain one of the highest in the semiconductor industry, driven by its highly efficient operating model's economies of scale.

Earnings, Cash & Competitive Moat

Wall St analysts are expecting earnings per share to decline 55.7% over the next twelve months, although estimates are likely to change post earnings.

Earnings are important, but we believe cash is king as you cannot pay bills with accounting profits. Micron Technology's free cash flow came in at $196 million in Q4, down 89.5% year on year.

Micron Technology Free Cash Flow

Micron Technology produced free cash flow of $3.2 billion in the last year, which is 10.4% of revenue. It's good to see positive free cash flow, and that puts the company in a position to reinvest, but we wouldn't mind seeing cashflow yield improve a little.

Micron Technology’s average return on invested capital (ROIC) over the last 5 years of 25.6% implies it has a strong competitive position and is able to invest in profitable growth over the long term.

Key Takeaways from Micron Technology's Q4 Results

Sporting a market capitalization of $56.2 billion, more than $9.33 billion in cash and with positive free cash flow over the last twelve months, we're confident that Micron Technology has the resources it needs to pursue a high growth business strategy.

It was less good to see that the revenue growth was quite weak and the revenue guidance for the next quarter missed analysts' expectations. Overall, this quarter's results could have been better. The company is flat on the results and currently trades at $49.9 per share.

Is Now The Time?

When considering Micron Technology, investors should take into account its valuation and business qualities, as well as what happened in the latest quarter. We cheer for everyone who is making the lives of others easier through technology, but in the case of Micron Technology we will be cheering from the sidelines. Its revenue growth has been weak, and analysts expect growth rates to deteriorate from there.

Micron Technology's price to earnings ratio based on the next twelve months is 14.8x. While we have no doubt one can find things to like about the company, we think there might be better opportunities in the market and at the moment don't see many reasons to get involved.
