Financial Performance and Metrics
Diodes has reported consistent financial performance, with annual net sales growing from $1.2 billion in 2020 to $1.3 billion in 2024, representing a compound annual growth rate of approximately 1.6%. The company's net income for the fiscal year 2024 was $44.0 million, or $0.95 per diluted share, compared to $227.2 million, or $4.91 per diluted share, in the previous year.
The company's gross profit margin for 2024 was 33.2%, down from 39.6% in 2023, primarily due to the overall reduction in end-market demand, continued inventory reductions by customers, and lower utilization in the company's factories. Diodes' operating cash flow for 2024 was $119.4 million, and its free cash flow was $46.0 million.
For the most recent quarter, Diodes reported revenue of $339.3 million and net income of $8.2 million. Revenue decreased 21.1% year-over-year, primarily due to decreased demand for semiconductor products and inventory adjustments by customers.
Liquidity
Diodes' balance sheet remains strong, with $322 million in cash, cash equivalents, restricted cash, and short-term investments as of the end of 2024. The company's total debt, including both short-term and long-term, stood at $52 million, demonstrating its financial stability and flexibility. Diodes has a debt-to-equity ratio of 0.018, a current ratio of 3.26, and a quick ratio of 1.99, further highlighting its strong financial position.
The company also has $146 million in available credit facilities, with $114 million unused as of December 31, 2024, providing additional financial flexibility.
Geographic and Market Diversification
Diodes' global reach is a significant advantage, with the majority of its revenue (72% in 2024) generated by its Asian and European subsidiaries. For the twelve months ended December 31, 2024, Asia represented 72% of net sales, Europe represented 15%, and the Americas represented 13%. The company's diverse customer base and end-market exposure have helped mitigate the impact of cyclical fluctuations in any single market.
In 2024, Diodes' revenue was derived from the following end-markets: industrial (23%), automotive (19%), computing (25%), consumer (19%), and communications (14%).
