What drove Micron's gross profit surge in Q4 2024?

Micron's gross profit surge in Q4 2024 was primarily driven by a combination of factors:

1. **Increase in Revenue**: Micron's total revenue for Q4 2024 reached $8.71 billion, surpassing analyst expectations. This increase in revenue is a direct result of strong demand for Micron's high-value products, such as HBM and LP5, which have been well-received in the market.
2. **Gross Margin Improvement**: The company's gross margin improved significantly, reaching 38.44% by the end of Q4 2024. This improvement can be attributed to a combination of factors, including increased average selling prices for Micron's DRAM and NAND products, cost reductions in manufacturing, and an improved product mix that includes higher-margin products like HBM and LP5.
3. **Operating Expenses Management**: Micron's focus on cost management and strategic investments in growth have allowed the company to maintain profitability despite increased operating expenses. The company reported a 15% increase in OpEx, reflecting investments in growth opportunities.

In summary, Micron's gross profit surge in Q4 2024 was driven by a combination of increased revenue, improved gross margins, and effective management of operating expenses.
