Material Changes vs. Prior Period
- Revenue Mix Shift: Memory sales increased 11% to $5.0 billion, driven by a 287% surge in NAND Flash sales (now 23% of total revenue). Imaging sales declined 8% to $687 million due to industry softness in mobile handsets.
- Pricing Pressure: Average selling prices (ASP) for DRAM fell 23% and NAND Flash fell 56% compared to 2006. This volume growth was insufficient to offset price declines, leading to a net loss.
- Profitability Decline: The company moved from a net income of $408 million in 2006 to a net loss of $320 million in 2007. Gross margin percentage dropped from 23% to 19%.
- Increased Leverage: Total debt increased significantly to $2.41 billion, primarily due to the issuance of $1.3 billion in Convertible Senior Notes in May 2007 to fund capital expansion.
- Inventory Build-up: Inventories increased by $591 million to $1.53 billion, resulting in a $20 million inventory write-down in Q4 2007 due to falling market prices.
Guidance, Outlook, and Risks
- Capital Spending: Management expects 2008 capital spending to approximate $2.5 billion, primarily for 300mm fabrication facilities to support NAND Flash growth.
- Restructuring: The company incurred a $19 million restructuring charge in Q4 2007 for workforce reductions and expects to incur additional charges through 2008.
- Legal Contingencies: Significant risks remain regarding ongoing antitrust investigations (DRAM, SRAM, Flash) by the DOJ and numerous class-action lawsuits alleging price-fixing. The company settled a direct purchaser DRAM class action in Q1 2007 for $81 million ($50M revenue charge, $31M SG&A charge).
- Intellectual Property: Ongoing litigation with Rambus and Mosaid regarding patent infringement poses potential liability risks.
- Outlook: Management anticipates continued growth in NAND Flash output in 2008 but warns that results could differ materially if ASP declines outpace cost reductions.
Investor Verification Checklist
- Inventory Valuation: Verify the adequacy of inventory reserves given the volatile semiconductor pricing environment and the $20M write-down already recorded.
- Debt Service: Assess the impact of the new $1.3 billion convertible debt and increased interest obligations on future cash flows.
- Antitrust Exposure: Monitor the status of DOJ investigations and class-action lawsuits, as final resolutions could result in significant, unpredictable liabilities.
- NAND Flash Margins: Evaluate whether the massive capital investment in NAND Flash capacity will yield sufficient margins given the 56% ASP decline in 2007.
- Joint Venture Cash Flow: Note that cash held by IM Flash and TECH joint ventures is not available to fund Micron's other operations, potentially constraining liquidity.
