Raising estimates slightly & raising target $18 to $20 on continued strength in commodity pricing; next step for the stock will likely come from better execution, which takes longer. While we have had a persistently bullish outlook on memory since early this year, DRAM and NAND have both been slightly better than we expected qtd, and certainly better than the company's cautious outlook starting the quarter. Having said that, we were pounding the table on the stock at $10, and we aren't now - we think from here, the stock will outperform more gradually as the company shows benefit from DRAM and NAND cost reduction.
Pricing continues to be better, though we'd argue that's increasingly discounted by the stock at these levels. DRAM supply remains tight, and with DRAM spending down sharply we'd expect continued tightness, albeit with a seasonal overlay, through 2017. As we wrote about last week, we have see sharp DRAM migration during 3q from producer's balance sheets to customer's balance sheets - but lean producer balance sheets into 4q should create slower supply growth to mitigate the negative impact of customer prebuying. DRAM supply growth seems likely to be sub 20% next year, which should lead to continued tightness. NAND is also very tight heading into seasonal strength , but with potential step functions in supply as suppliers bring 3D online we'd expect more ups and downs through next year, but still with solid economics.
The key to Micron stock from here will be company-specific execution, where we look for 2 key transitions to gradually improve in costs, realized prices, & EPS. Micron has sharply underperformed peers on profitability the last 18 months, due to extended challenges integrating the manufacturing processes of the combined Elpida and Micron fabs (the 20 nm transition was the first process to roll out to all of the fabs globally), and limited cost benefits in the planar NAND business. While we don't expect Micron to regain the profit levels of Korean peers, we do expect to get closer in the coming quarters.
Execution in DRAM has already started to improve - we expect continued follow through. With 22% sequential bit growth last quarter, and higher bit growth this quarter, we are clearly seeing the inflection from the company's ramp of the 20 nm process. There is so much bit growth that we haven't seen benefits that we had hoped for from mix shift towards mobile, and growing bits by that much does create some strain, but in a fixed cost business reflects substantial cost reduction, and we expect substantial improvement in gross margins over the next couple of quarters. The key will be the fast migration to 18 nm that the company has been talking about, as a more mature integration of Elpida positions them to avoid the 20 nm delays. Fast migration to 18 nm should avoid repeating the relative underperformance that the company suffered in the 20 nm migration. We also note signs of better recent execution, with leadership on the GDDR5x graphics RAM standard and better mobile qualifications.
3D NAND transition moving in the right direction, though the pace of the transition has pressured earnings, and some risk remains. We see Micron moving from worst in class cost structure on planar to a middle of the pack cost structure in 3D, which should be a significant positive over time. But we had underestimated how difficult this transition has been, thus far. Taking planar capacity offline to convert to 3D is painful in a fixed cost business, and we estimate that margins should start to improve sharply in the November quarter. It's still not entirely without risk, as the pace of the 3D ramp is so steep that there could be qualification issues that impact pricing, as we saw when the company brought it's Singapore fab up on NAND a couple of years ago. But the potential delta here is substantial, particularly with a relatively quick and less capital intensive migration from 32 layer to 64 layer coming. One key aspect of this transition is that there is substantial negative impact to the May and August quarters from taking planar capacity offline for conversion to 3D - this is low hanging fruit for improvement once the new capacity comes back.
Details on our estimate changes, and new price target goes from $18 to $20 - Our estimate changes are relatively small; we see EPS above the guided range for the August quarter (management guided to a loss of $0.16 to $0.24, we see a loss of $0.13), and we see November quarter EPS at $0.08 vs. our prior $0.06. We'd emphasize that these are small changes, as we had already budgeted for healthy improvement in pricing and were already at the high end of company guidance for the current quarter. For our price target, we are raising our through-cycle EPS estimate from $1.65 to $1.85, based on continued softer DRAM capex - and we expect to be at this EPS run rate within 12 months. We see "through cycle" earnings at slightly above the midpoint of peak ($3.50
