What Diodes’ latest earnings tell you about the business

Diodes (DIOD) recently reported second quarter 2026 earnings that showed year over year growth in both sales and net income, alongside guidance that points to higher expected revenue in the coming quarter.

For the second quarter ended June 30, 2026, Diodes reported sales of US$445.53 million compared with US$366.21 million a year earlier. Net income was US$46.65 million compared with US$46.10 million for the prior year period, with basic earnings per share from continuing operations of US$1.02 versus US$0.99.

On a diluted basis, earnings per share from continuing operations were US$1.00 compared with US$0.99 a year earlier. These figures give you a sense of how much profit the company generated for each share after accounting for potential share dilution.

Looking at the first half of 2026, Diodes reported sales of US$851 million versus US$698.33 million for the same period in 2025. Net income for the six months was US$61.61 million compared with US$41.66 million, with basic earnings per share from continuing operations of US$1.34 versus US$0.90.

Diluted earnings per share from continuing operations for the six month period were US$1.33 compared with US$0.90 a year earlier. For investors tracking longer term progress, this half year snapshot sits alongside the company’s reported annual revenue of US$1.63b and net income of US$86.09 million.

Management also provided earnings guidance for the third quarter of 2026. Diodes expects revenue of about US$510 million, plus or minus 3%. At the midpoint, this outlook indicates a 30% year over year increase and a 14% sequential increase, which reflects management’s stated expectations for the next reporting period.

Diodes’ latest update has come alongside an active period for the stock, with the share price at US$100.94 after a 7 day share price return of 22.96% and a year to date share price return of 96.27%. Over the longer term, total shareholder return of 98.58% over 1 year and 25.70% over 3 years points to stronger recent momentum than over the medium term. This suggests the latest earnings, guidance and buyback activity are being viewed as supportive, while the 1 day share price return of 4.02% and 90 day share price return of 2.43% show that sentiment can still shift quickly around results and board changes.

Diodes has surged close to US$101 while analyst targets and intrinsic value estimates sit much higher. Is the real fair value now closer to the recent price action or nearer the top end of that valuation range?

Most Popular Narrative: 33.4% Overvalued

Against the latest close at $100.94, the most followed narrative for Diodes pegs fair value at $75.67 using a 10.65% discount rate. That gap reflects a view that the current price embeds richer expectations than the narrative implies.

Rising demand for Diodes' solutions in AI-related computing and the broader ecosystem of connected devices (including data centers, servers, industrial automation, and IoT) is boosting revenue momentum and contributing to consistent market share gains, improving longer-term top-line growth visibility. Tailwinds from the global trend toward digitalization, industrial automation, and regulatory push for energy efficiency are expanding demand for Diodes' power-efficient semiconductor solutions, increasing long-term addressable markets and supporting multi-year revenue growth.

Want to see what sits behind that fair value for Diodes? The narrative leans on faster revenue compounding, higher margins, and a future earnings multiple that needs to line up with those targets.

Result: Fair Value of $75.67 (OVERVALUED)

However, Diodes’ heavy reliance on Asian revenue and ongoing high inventory levels could quickly challenge this overvaluation narrative if demand or pricing softens.
