Diodes Incorporated (NASDAQ:DIOD) reported financial results for the third quarter ended September 30, 2026, with revenue of $532.6 million, a record for the semiconductor company. Revenue increased 35.8 percent from $392.2 million a year earlier and 19.5 percent from the second quarter. During the period, the company completed its Acquisition of ElevATE Semiconductor, a provider of high-performance integrated circuits for the automated test equipment market, and closed a private Placement of convertible senior notes. The results show higher revenue alongside a larger share of gross profit, a combination that shaped most of the quarter's reported figures.

Revenue Growth and Gross Margin Expansion

Gross profit reached $192.5 million, compared with $120.5 million in the third quarter of 2025 and $147.6 million in the prior quarter. GAAP gross margin rose to 36.1 percent, an increase of 540 basis points from 30.7 percent a year earlier and 300 basis points from 33.1 percent in the second quarter. Non-GAAP Gross Profit was $192.9 million, with a non-GAAP gross margin of 36.2 percent after excluding $0.4 million of inventory accounting tied to the ElevATE acquisition.

Sequential growth also contributed to the quarter. Revenue rose 19.5 percent from $445.5 million in the second quarter, while gross profit increased from $147.6 million. The combination of higher revenue and a wider gross margin than the prior quarter indicates that the improvement was not limited to a single year-over-year comparison. EBITDA, which the company reported at 16.8 percent of revenue, was lower as a share of revenue than the 18.7 percent recorded in the second quarter.

Gross profit grew by nearly 60 percent over the year, outpacing the 35.8 percent increase in revenue. EBITDA rose to $89.7 million, or 16.8 percent of revenue, compared with $46.6 million, or 11.9 percent of revenue, in the third quarter of 2025.

Earnings and Cash Flow Measures

GAAP Net Income was $43.7 million, or $0.95 per diluted share, compared with $14.3 million, or $0.31 per diluted share, a year earlier. Non-GAAP adjusted net income reached $54.5 million, or $1.18 per diluted share, compared with $17.2 million and $0.37 per diluted share in the third quarter of 2025. The non-GAAP EPS figure increased 219 percent over that period and 68.6 percent sequentially. Share-based compensation of $7.4 million, net of tax, reduced reported Earnings by $0.16 per diluted share, according to the company's disclosure.

Operating cash flow totaled $97.2 million, and free cash flow reached $43.9 million after $53.2 million of capital expenditures. The company reported net cash flow of $134.1 million, a figure that includes approximately $35 million directed to its stock buyback program. Cash generation during the quarter therefore supported both acquisition activity and capital returns to shareholders.

Acquisition, Financing and Revenue Expectations

The ElevATE acquisition expands the company's presence in the automated test equipment segment, where it now offers integrated circuits for test applications. The private placement of 0.00 percent convertible senior notes due 2031, totaling $375 million in aggregate principal, adds a long-dated funding source. Because the notes carry no coupon, the borrowing does not add cash interest expense, although the conversion feature may affect future share count depending on the stock price.

The outlook also includes an expectation of further non-GAAP gross margin expansion, reaching 37.0 percent at the midpoint, which would extend the sequential improvement recorded during the quarter. Management pointed to increasing earnings Leverage and continued cash generation as part of the overall view.

Management expects fourth quarter revenue of approximately $550 million, plus or minus 3 percent, which would represent a 40.4 percent increase year over year and a 3.2 percent sequential increase at the midpoint. For full-year 2026, revenue is projected to rise approximately 30 percent over 2025 at the midpoint, with non-GAAP gross margin expected to reach 37.0 percent at the midpoint.

Final Takeaways

The third quarter results show Diodes expanding revenue at a faster rate than its earlier periods, while gross margin and earnings measures improved in parallel. The acquisition of ElevATE and the convertible notes place the company's Capital Structure and product portfolio in a different position than a year ago. The fourth quarter guidance and full-year projections will indicate whether the pace of growth and margin improvement continues as the company integrates its recent activity.
