Market Report
Diodes (DIOD) traded at $105.32 on May 29, 2026. The local yfinance snapshot showed a 52-week range of $42.28-$117.80, a 50-day average of $92.16, and a 200-day average of $64.56.
The stock has already rebounded sharply. yfinance showed a 137.2% one-year return and a 104.8% YTD return, leaving DIOD above both major moving averages but still below its 52-week high.
DIOD fits the AI and semiconductor queue as an analog, discrete, power, logic, and mixed-signal semiconductor supplier with exposure to automotive, industrial, computing, consumer, communications, AI server, data center, storage, and edge computing applications.
Market read: Buy with a $125 target. This is below the yfinance mean and median analyst target of $129.50, but recognizes strong recovery momentum and the risk that the stock has already doubled YTD.
Sentiment Analyst
Sentiment Report
Sentiment is positive after Q1 2026 results.
Q1 revenue was $405.5 million, compared with $332.1 million in Q1 2025 and $391.6 million in Q4 2025. Management described this as 22% year-over-year growth and above-seasonal 3.5% sequential growth.
GAAP gross profit was $128.8 million, and GAAP gross margin was 31.8%. GAAP net income was $15.0 million, or $0.32 diluted EPS, compared with a GAAP net loss in the prior-year quarter. Non-GAAP adjusted net income was $19.8 million, or $0.43 diluted EPS.
Management cited demand recovery and momentum across automotive, industrial, and AI-server related applications. It also said Q1 was the fifth consecutive quarter of double-digit year-over-year revenue growth.
Sentiment read: Buy because revenue growth, EPS recovery, and management commentary are all moving in the right direction.
News Analyst
News Report
The May 7, 2026 Q1 release is the key current news item.
For Q2 2026, Diodes expects revenue of approximately $435 million plus or minus 3%, implying another double-digit year-over-year increase and sequential growth at the midpoint. The company also guided to GAAP gross margin of 32.8% plus or minus 1% and non-GAAP adjusted EPS of $0.60 plus or minus $0.10.
Q1 EBITDA was $49.4 million, or 12.2% of revenue. Operating cash flow was $64.3 million, and free cash flow was $32.4 million.
The 2025 annual report shows why DIOD belongs in the AI queue. Computing revenue grew 25% in 2025, led by AI server, storage, data center, and edge computing applications. Addressable content in AI servers rose to approximately $103 per box in 2025 from $90 in 2024 and $53 in traditional servers previously.
News read: Diodes is not a pure AI accelerator company, but it is participating in AI infrastructure through higher semiconductor content in servers, data center systems, storage, and edge computing.
Fundamentals Analyst
Fundamentals Report
Fundamentals show a profitable semiconductor recovery with a strong balance sheet.
yfinance showed market cap of approximately $4.84 billion, enterprise value of approximately $4.60 billion, total revenue of approximately $1.56 billion, operating cash flow of approximately $223.1 million, free cash flow of approximately $145.4 million, total cash of approximately $404.2 million, and total debt of approximately $104.9 million.
The Q1 2026 company release showed an even cleaner balance sheet snapshot: approximately $409 million in cash, cash equivalents, restricted cash, and short-term investments; approximately $55 million of total debt; and approximately $891 million of working capital.
yfinance showed revenue growth of 22.1%, gross margin of 31.3%, operating margin of 4.9%, profit margin of 5.5%, trailing P/E of 56.9x, forward P/E of 21.1x, and price/sales of 3.11x.
Fundamental read: Buy because Diodes is moving from trough profitability toward operating leverage, while the balance sheet gives it flexibility.
II. Research Team Decision
Bull Researcher
Bull Research
The bull case is that DIOD is a broad-based semiconductor recovery with specific AI-server content growth.
Q1 revenue increased 22% year over year, Q1 non-GAAP EPS more than doubled year over year to $0.43, and Q2 guidance calls for about $435 million of revenue with $0.60 non-GAAP EPS at the midpoint.
The 2025 annual report adds strategic evidence. Revenue grew 13% to $1.5 billion, computing revenue grew 25% led by AI server, storage, data center, and edge computing, and automotive plus industrial represented 42% of product revenue.
The company also has three-year interim targets of $2.0 billion revenue, approximately $700 million gross profit, 35%+ gross margin, and more than $4.00 non-GAAP EPS.
Bull conclusion: DIOD can continue to re-rate if AI-server content, automotive, industrial, and manufacturing utilization drive margin expansion.
Bear Researcher
Bear Research
The bear case is that the stock has already priced in a large recovery.
DIOD traded at $105.32, up more than 100% YTD and close to its $117.80 52-week high. yfinance showed trailing P/E of 56.9x, which is high because trailing earnings still reflect the downturn.
Gross margin is improving but still well below the company's longer-term 40% gross-profit-margin ambition. Q1 GAAP gross margin was 31.8%, and Q2 guidance calls for 32.8% plus or minus 1%.
Risks include semiconductor cyclicality, inventory corrections, end-market demand volatility, customer order deferrals, competition, manufacturing utilization, automotive/industrial execution, China/Taiwan/geopolitical exposure, tariffs and trade restrictions, currency, acquisitions, cybersecurity, and the possibility that AI-server content growth slows.
Bear conclusion: DIOD can underperform if the cycle stalls before margins and EPS catch up with the stock rally.
Research Manager
Research Manager Synthesis
The bull case is stronger than the bear case at current fundamentals. DIOD is showing double-digit revenue growth, improving gross margin, operating leverage, positive free cash flow, net cash, and clear AI-server content growth.
The bear case is valuation after a sharp rally. That risk matters, so the target should not be far above consensus.
The correct conclusion is Buy with a restrained target. The $125 target is below the yfinance mean and median target of $129.50, but still provides attractive upside from $105.32.
Synthesis: assign Buy with a $125 target.
III. Trading Team Plan
Trader
Trader View
DIOD is above its $92.16 50-day average and $64.56 200-day average, while still below the $117.80 52-week high.
Upside trigger: Q2 revenue above the top end of guidance, non-GAAP EPS above $0.70, gross margin moving above 34%, stronger AI-server content commentary, or progress toward the $2.0 billion revenue and 35%+ gross-margin interim targets.
Downside trigger: revenue below the low end of guidance, weaker automotive or industrial orders, AI-server content disappointment, gross-margin pressure, or a renewed semiconductor inventory correction.
Trading plan: Buy with a $125 6-12 month target. Reassess near the 52-week high and after Q2 results confirm whether operating leverage is accelerating.
IV. Risk Management Team Decision
Aggressive Analyst
Aggressive Risk View
Aggressive investors can buy DIOD for cyclical recovery plus AI-server semiconductor content expansion.
The risk is timing. After a large rally, the stock may need another earnings beat before it can move materially higher.
Aggressive conclusion: Buy.
Conservative Analyst
Conservative Risk View
Conservative investors should respect the rally and position size carefully.
DIOD has net cash and improving profitability, but the stock is near a 52-week high and trailing valuation is elevated.
Conservative conclusion: Hold to small Buy.
Neutral Analyst
Neutral Risk View
The neutral view is constructive.
The balance sheet, Q2 guidance, free cash flow, and AI-server content growth justify a positive stance, while valuation argues for a restrained target.
Neutral conclusion: Buy with a $125 target.

Rating: Buy Price Target: 125
Horizon: 6-12 months Current Price Reference: $105.32 on 2026-05-29
Diodes is rated Buy. It is included in the AI and semiconductor queue because it supplies analog, discrete, power, logic, and mixed-signal semiconductors into automotive, industrial, computing, consumer, communications, AI server, data center, storage, and edge-computing applications.
The latest major financial update is Q1 2026 results. Revenue was $405.5 million, compared with $332.1 million in Q1 2025 and $391.6 million in Q4 2025. Management described the quarter as 22% year-over-year revenue growth and 3.5% sequential growth.
GAAP gross profit was $128.8 million, and GAAP gross margin was 31.8%. GAAP net income was $15.0 million, or $0.32 diluted EPS. Non-GAAP adjusted net income was $19.8 million, or $0.43 diluted EPS. EBITDA was $49.4 million, or 12.2% of revenue. Operating cash flow was $64.3 million, and free cash flow was $32.4 million.
Q2 2026 guidance calls for revenue of approximately $435 million plus or minus 3%, GAAP gross margin of 32.8% plus or minus 1%, and non-GAAP adjusted EPS of $0.60 plus or minus $0.10. Management said demand recovery is being driven by automotive, industrial, and AI-server related applications.
The 2025 annual report supports the AI exposure. Full-year 2025 revenue grew 13% to $1.5 billion. Computing market revenue increased 25%, led by AI server, storage, data center, and edge computing applications. Automotive and industrial represented 42% of 2025 product revenue. Addressable content in AI servers rose to approximately $103 per box in 2025, up from $90 in 2024 and $53 in traditional servers previously.
yfinance showed a latest price of $105.32, market cap of approximately $4.84 billion, enterprise value of approximately $4.60 billion, 52-week range of $42.28-$117.80, total revenue of approximately $1.56 billion, revenue growth of 22.1%, gross margin of 31.3%, operating margin of 4.9%, profit margin of 5.5%, operating cash flow of approximately $223.1 million, free cash flow of approximately $145.4 million, total cash of approximately $404.2 million, total debt of approximately $104.9 million, trailing P/E of 56.9x, forward P/E of 21.1x, price/sales of 3.11x, and mean and median analyst targets of $129.50.
The main risks are valuation after a sharp rally, semiconductor cyclicality, inventory corrections, end-market demand volatility, order deferrals, competition, manufacturing utilization, automotive/industrial execution, China/Taiwan/geopolitical exposure, tariffs and trade restrictions, currency, acquisitions, cybersecurity, and slower AI-server content growth.
The $125 target is deliberately below the yfinance mean and median target of $129.50. It reflects strong Q1 execution, Q2 growth guidance, a net-cash balance sheet, free cash flow, and AI-server content expansion, while acknowledging that the stock has already risen sharply.
