SanDisk (SNDK) guides on its Q1 earnings call (webcast) for Q2 revenue of $950M-$1.05B, below a consensus of $1.31B. 2012 sales are expected to fall from 2011 levels (consensus is for 4.1% growth). SanDisk is also guiding for a Q2 gross margin of just 26%-30% (down from Q4's 42.9%), and says some phone OEMs are reducing memory card capacity. SanDisk's lack of exposure to Apple and Samsung appears to be hurting its market position. SNDK -7.3% AH.
