What is the source of Micron's explosive performance? Strong performance is generally influenced by factors such as price increases, increased shipments, a higher proportion of high gross profit products, and cost reductions. Previously, Micron's financial report forecast https://(x.com)/qinbank/status/2068979504081469789 provided a framework for breaking down performance, and then we will break it down according to this framework. Simply put, ASP/price increase is the primary driver, product mix is the secondary driver, bit shipments only make a small positive contribution, and high cost efficiency/execution is mainly driven by profit margin amplifiers. 1. ASP/Price: The biggest source of this season's performance DRAM revenue was $31.3 billion, accounting for 76% of total revenue and a month on month increase of 67%; But DRAM bit shipments only saw low single digit growth, while prices increased by 160%. NAND revenue was 9.9 billion US dollars, accounting for 24% of total revenue, with a month on month growth of 99%; The shipment of NAND bits is also experiencing moderate single digit growth, with a median price increase in the 80% range. A rough breakdown can be seen as follows: In the+67% month on month growth of DRAM, about 60 percentage points come from price/mix, with only low single digits coming from bit; In the+99% month on month growth of NAND, about 80% comes from price/mix, the median comes from bit, and the rest is the multiplier effect of both price and shipment increases. Therefore, approximately 90% of this quarter's revenue increase is likely to come from the growth of ASP, rather than volume. This judgment is also consistent with the management's statement on gross profit margin: the increase in Q3 gross profit margin is mainly driven by higher prices. 2. Bit shipment: contributes, but not the core Bit shipments have not exploded. DRAM bits only increase by low single digits, while NAND bits increase by mid single digits; This indicates that performance is not driven by "selling more capacity", but by "selling the same or slightly more bits at a much higher price". From the business department, it can also be seen that: The growth of Cloud Memory business is driven by both higher prices and bit shipments; Core Data Center business grew by 103%, mainly driven by price and favorable mix; Although the revenue of the Mobile and Client business increased by 49%, the bit shipments actually decreased, indicating that the shipping pressure here was almost completely offset by prices. 3. Product mix: very important and a source of growth for 'higher quality' The core of Mix lies in Micron selling more supply to high-value markets such as AI data centers HBM、 High end DDR, enterprise grade SSD, data center SSD. Micron's data center revenue exceeded $25 billion this quarter, with an annualized increase of over $100 billion; Data center SSD revenue exceeded $5 billion, more than doubling month on month. The business structure is also tilting towards data centers: Cloud Memory Business Unit has a revenue of $13.769 billion, and Core Data Center Business Unit has a revenue of $11.524 billion, accounting for approximately 61% of the company's revenue; Last season, these two departments accounted for approximately 56% of the total. This indicates that Micron is not only selling at a high price, but also allocating production capacity to higher value customers and products. HBM is also key evidence of mix improvement. Micron stated that the production ramp up speed of HBM4 12 high is twice that of HBM3E 12 high, and HBM4 has already shipped over $1 billion in revenue; At the same time, the company also mentioned that AI is driving memory architecture selection and product mix towards higher performance and higher value products. 4. High cost efficiency/execution: Amplify profit margin, but not the main narrative of this season The cost side has indeed helped the gross profit margin, but this quarter cannot be simply attributed to 'cost reduction'. According to the GAAP report, Q3 revenue increased from $23.86 billion in the previous quarter to $41.456 billion, but COGS only increased from $6.105 billion to $6.40 billion; That is to say, with an increase of $17.596 billion in revenue, costs only increased by $295 million, and almost all of the new revenue became gross profit. Micron's own explanation is: The increase in gross profit margin is mainly driven by higher prices, while benefiting from continued execution and favorable mix; The company did not attribute the increase in gross profit margin this quarter mainly to the decrease in unit costs. More importantly, Micron also reminds that in the future, high-performance and high-value products will have higher complexity, with LP5 to LP6, DDR5 to DDR6, and updated generation HBM all bringing higher bit costs. The cost per bit of hybrid DRAM may even increase from the current level. Micron's latest financial report is a combination of "ASP revaluation caused by tight supply and demand+AI/HBM/data center mix up+cost leverage". The easiest one to reverse is ASP, but what makes this round stronger than traditional cycles is that Micron has signed multiple strategic customer agreements, some of which include take or pay, price ranges, and long-term supply commitments, which will increase performance visibility. The most important thing to focus on later is: The Q4 guidance remains strong, with a revenue guidance of $50 billion ± $1 billion and a gross profit margin of approximately 86%. However, the management also stated that the Q4 gross profit margin outlook reflects a "significant slowdown in price increases". This means that the direction is still strong, but the marginal acceleration of ASP may have started to slow down. Of course, the core here is that Micron's current "effective capacity utilization rate" should be very close to full load, especially AI related DRAM/HBM and advanced NAND; The real constraint on the continued increase in revenue at present is not the utilization rate, but the insufficient addition of effective production capacity. The core of ASP growth is still supply far below demand Overall, Micron is not in the stage of low utilization recovery, but in the stage of high utilization+high ASP+high mix+expansion bottleneck. This is beneficial for the gross profit margin, as fixed costs are well absorbed; As for whether the demand and prices can continue to bear the additional production capacity in 2027-2028 in the longer term.
