**Item 2.02 Results of Operations and Financial Condition.**

On November 6, 2025, Diodes Incorporated (the "Company") issued a press release announcing its third quarter ended September 30, 2025 financial results. A copy of the press release is furnished as Exhibit 99.1.

In the press release, the Company utilizes financial measures and terms not calculated in accordance with generally accepted accounting principles in the United States ("GAAP") in order to provide investors with an alternative method for assessing the Company's operating results in a manner that enables investors to more thoroughly evaluate its current performance as compared to past performance. The Company also believes these non-GAAP measures provide investors with a more informed baseline for modeling the Company's future financial performance. Management uses these non-GAAP measures for the same purpose. The Company believes that investors should have access to the same set of tools that management uses in analyzing results. These non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for or superior to GAAP results and may differ from similar measures used by other companies. See Exhibit 99.1 for a description and reconciliation with GAAP of the non-GAAP measures used.

The information furnished in this Item 2.02, including the exhibit incorporated by reference, will not be treated as "filed" for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise subject to the liabilities of that section. This information will not be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended (the "Securities Act"), or into another filing under the Exchange Act, unless that filing expressly refers to specific information in this Report.

**Item 7.01 Regulation FD Disclosure.**

The press release furnished as Exhibit 99.1 also provides an update on the Company's business outlook, that is intended to be within the safe harbor provided by the Private Securities Litigation Reform Act of 1995 (the "Act") as comprising forward looking statements within the meaning of the Act.

The information furnished in this Item 7.01, including the exhibit incorporated by reference, will not be treated as "filed" for the purposes of Section 18 of the Exchange Act, or otherwise subject to the liabilities of that section. This information will not be deemed incorporated by reference into any filing under the Securities Act, or into another filing under the Exchange Act, unless that filing expressly refers to specific information in this Report.

**Item 8.01 Other Events.**

From time to time, Diodes Incorporated (the "Company") may give corporate presentations to its customers, suppliers and other related interested parties. Copies of the Company's corporate presentation slides, updated on November 6, 2025, are attached herewith as Exhibit 99.2 and Exhibit 99.3. Exhibit 99.2 provides an update focused on the Company's third quarter 2025 financial results and Exhibit 99.3 is used in the Company's investor relations presentations.

**<u>Forward-Looking Statements</u>** 

Statements in this Current Report on Form 8-K (including in the documents attached as Exhibit 99.1, Exhibit 99.2, and Exhibit 99.3) contain forward-looking statements that involve future risks and uncertainties as contemplated by the safe harbor provided by the Private Securities Litigation Reform Act of 1995. All statements, other than statements of historical facts, included in this Current Report on Form 8-K (including the documents attached as Exhibit 99.1, Exhibit 99.2, and Exhibit 99.3 should be regarded as "forward-looking statements" and Exhibit 99.1, Exhibit 99.2, and Exhibit 99.3 contain a more detailed listing of the risks and uncertainties associated with those forward-looking statements.

**Diodes Incorporated Reports Third Quarter Fiscal 2025 Financial Results**

*Continues Double Digit Year-over-Year Growth and over 12% YTD Growth* 

*over Prior Year Period* 

**Plano, Texas – November 6, 2025** -- Diodes Incorporated (Diodes) (Nasdaq: DIOD) today reported its financial results for the third quarter ended September 30, 2025.

**Third Quarter Highlights**

• Revenue was $392.2 million, compared to $350.1 million in the third quarter 2024 and $366.2 million in the prior quarter;

• GAAP gross profit was $120.5 million, compared to $118.0 million in the same quarter a year ago and $115.3 million in the prior quarter;

• GAAP gross profit margin was 30.7 percent, compared to 33.7 percent in the third quarter of 2024 and 31.5 percent in the prior quarter;

• GAAP net income was $14.3 million, compared to GAAP net income of $13.7 million in the same quarter a year ago and GAAP net income of $46.1 million last quarter;

• Non-GAAP adjusted net income was $17.2 million, compared to $20.1 million in the same quarter a year ago and $15.0 million in the prior quarter;

• GAAP EPS was $0.31 per diluted share, compared to GAAP EPS of $0.30 per diluted share in the third quarter of 2024 and GAAP EPS of $0.99 per share in the prior quarter;

• Non-GAAP EPS was $0.37 per diluted share, compared to $0.43 per diluted share in the same quarter a year ago and $0.32 per diluted share in the prior quarter;

• Excluding $5.4 million, net of tax, non-cash share-based compensation expense, both GAAP net income and non-GAAP adjusted net income would have increased by $0.12 per diluted share;

• EBITDA was $46.6 million, or 11.9 percent of revenue, compared to $46.9 million, or 13.4 percent of revenue during the same quarter last year and $84.5 million, or 23.1 percent of revenue in the prior quarter;

• Achieved $79.1 million cash flow from operations and $62.8 million of free cash flow, including $16.3 million of capital expenditures. Net cash flow was a positive $59.3 million; and

• Free cash flow per share was $1.35 for the quarter and $4.02 per share for the trailing twelve months, approaching the historical high of $4.34 per share in 2021.

Commenting on the results, Gary Yu, President and CEO of Diodes, stated, "Revenue in the quarter increased 7% sequentially and 12% year-over-year driven by strong demand across the general computing market, including for AI-related server applications as well as data center and edge computing. Our global point of sales (POS) increased the strongest in Asia followed by North America. Additionally, our channel inventory is at healthy levels, decreasing again this quarter in terms of dollars and weeks with overall inventory dollars decreasing over 25% from peak levels.

"Even though the rate of recovery in the automotive and industrial markets continues to be slower than expected, revenue increased both sequentially and year-over-year in both of

------

these end markets. When coupled with the computing market growing the strongest along with consumer also increasing sequentially, product mix unfavorably weighed on gross margin during the quarter. Future margin expansion will be driven by ongoing improvements in product mix as the pace of recovery accelerates in our higher-margin automotive and industrial end markets combined with increased new product introductions in all target markets as well as improved loading across our manufacturing facilities.

"At the mid-point of our fourth quarter guidance, we expect to achieve approximately 12% growth for the full year. Looking forward, we are gaining increasing confidence in broader demand improvements in the automotive and industrial markets. Diodes is gaining increasing market share in the automotive market with new programs scheduled to launch early next year combined with increasing content in industrial applications like AI robotics, power management, medical and factory automation."

**Third Quarter 2025** 

Revenue for third quarter 2025 was $392.2 million, compared to $350.1 million in the third quarter 2024 and $366.2 million in the second quarter 2025.

GAAP gross profit for the second quarter 2025 was $120.5 million, or 30.7 percent of revenue, compared to $118.0 million, or 33.7 percent of revenue, in the third quarter of 2024 and $115.3 million, or 31.5 percent of revenue, in the second quarter 2025.

GAAP operating expenses for third quarter 2025 were $108.9 million, or 27.8 percent of revenue, and on a non-GAAP basis were $103.1 million, or 26.3 percent of revenue, which excludes $5.9 million acquisition-related intangible asset cost. GAAP operating expenses in the third quarter 2024 were $96.1 million, or 27.5 percent of revenue and in the second quarter 2025 were $105.9 million, or 28.9 percent of revenue.

Third quarter 2025 GAAP net income was $14.3 million, or $0.31 per diluted share, compared to GAAP net income in the third quarter 2024 of $13.7 million, or $0.30 per diluted share and GAAP net income in the second quarter 2025 of $46.1 million, or $0.99 per diluted share.

Third quarter 2025 non-GAAP adjusted net income was $17.2 million, or $0.37 per diluted share, which excluded, net of tax, $4.8 million of acquisition-related intangible asset amortization cost and $1.9 million of unrealized gain on investments. This compares to non-GAAP adjusted net income of $20.1 million, or $0.43 per diluted share, in the third quarter 2024 and $15.0 million, or $0.32 per diluted share, in the second quarter 2025.

(See the reconciliation tables of GAAP net income to non-GAAP adjusted net income near the end of this release for further details.)

Included in third quarter 2025 GAAP and non-GAAP adjusted net income was approximately $5.4 million, net of tax, non-cash share-based compensation expense. Excluding share-based compensation expense, GAAP earnings per share ("EPS") and non-GAAP adjusted EPS would have increased by $0.12 per share for the third quarter 2025, compared to $0.13 per share in the third quarter 2024 and $0.10 for the second quarter 2025.

EBITDA (a non-GAAP measure), which represents earnings before net interest expense, income tax, depreciation and amortization, in the third quarter 2025 was $46.6 million, or 11.9 percent of revenue, compared to $46.9 million, or 13.4 percent of revenue, in the third quarter 2024 and $84.5 million, or 23.1 percent of revenue, in the second quarter 2025. For a reconciliation of GAAP net income to EBITDA, see the table near the end of this release for further details.

For the third quarter 2025, net cash provided by operating activities was $79.1 million. Net cash flow was positive $59.3 million. Free cash flow (a non-GAAP measure) was $62.8 million, which includes $16.3 million of capital expenditures.

**Balance Sheet** 

As of September 30, 2025, the Company had approximately $392 million in cash and cash equivalents, restricted cash, and short-term investments. Total debt (including long-term and short-term) amounted to approximately $58 million and working capital was approximately $890 million.

The results announced today are preliminary and unaudited, as they are subject to the Company finalizing its closing procedures and completion of the quarterly review by its independent registered public accounting firm. As such, these results are subject to revision until the Company files its Form 10-Q for the quarter ending September 30, 2025.

------

**Business Outlook** 

Gary Yu further commented, "For the fourth quarter of 2025, we expect revenue to be approximately $380 million, plus or minus 3 percent, representing 12 percent over the prior year period at the mid-point, which will be the fifth consecutive quarter of year-over-year growth. GAAP gross margin is expected to be 31.0 percent, plus or minus 1 percent. Non-GAAP operating expenses, which are GAAP operating expenses adjusted for amortization of acquisition-related intangible assets, are expected to be approximately 27.0 percent of revenue, plus or minus 1 percent. We expect net interest income to be approximately $1.0 million. Our income tax rate is expected to be 18.5 percent, plus or minus 3 percent, and shares used to calculate diluted EPS for the fourth quarter are anticipated to be approximately 46.4 million."

Amortization of acquisition-related intangible assets of $4.8 million, after tax, for previous acquisitions is not included in these non-GAAP estimates.

**<u>ADJUSTED NET INCOME AND ADJUSTED EARNINGS PER SHARE</u>**

The Company's financial statements present net income and earnings per share that are calculated using accounting principles generally accepted in the United States ("GAAP"). The Company's management makes adjustments to the GAAP measures that it feels are necessary to allow investors and other readers of the Company's financial releases to view the Company's operating results as viewed by the Company's management, board of directors and research analysts in the semiconductor industry. These non-GAAP measures are not prepared in accordance with, and should not be considered alternatives or necessarily superior to, GAAP financial data and may be different from non-GAAP measures used by other companies. Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies' non-GAAP financial measures, even if they have similar names. The explanation of the adjustments made in the table above, are set forth below:

***Detail of non-GAAP adjustments***

**<u>Amortization of acquisition-related intangible assets</u> –** The Company excluded this item, including amortization of developed technologies and customer relationships. The fair value of the acquisition-related intangible assets is amortized using straight-line methods which approximate the proportion of future cash flows estimated to be generated each period over the estimated useful life of the applicable assets. The Company believes that exclusion of this item is appropriate because a significant portion of the purchase price for its acquisitions was allocated to the intangible assets that have short lives and exclusion of the amortization expense allows comparisons of operating results that are consistent over time for both the Company's newly acquired and long-held businesses. In addition, the Company excluded this item because there is significant variability and unpredictability among companies with respect to this expense.

**<u>Board member retirement</u>** – The Company excluded costs related to the retirement of a board member. These costs represent cash payments and the accelerated vesting of previously issued stock awards. The Company feels it is appropriate to exclude these costs since they don't represent ongoing operating expenses and will present investors with a more accurate indication of our continuing operations.

**<u>Acquisition related costs</u> –** The Company excluded expenses associated with previous acquisitions of that typically consist of advisory, legal and other professional and consulting fees. These costs were expensed as they were incurred and as services were received, and in which the corresponding tax adjustments were made for the non-deductible portions of these expenses. The Company believes the exclusion of the acquisition related costs provides investors with a more accurate reflection of costs likely to be incurred in the absence of an unusual event such as an acquisition and facilitates comparisons with the results of other periods that may not reflect such costs.

**<u>Insurance recovery for manufacturing facility</u>** – The Company recorded gains related to insurance recovery for a manufacturing facility in Asia. The Company believes the exclusion of the insurance recovery provides investors with a more accurate reflection of the continuing operations of the Company and facilitates comparisons with the results of other periods which may not reflect such gains.

**<u>Unrealized gain on investments</u>** – The Company excluded unrealized mark-to-market adjustments on various equity related investments. The Company believes this is not reflective of the ongoing operations and exclusion of this provides investors an enhanced view of the Company's operating results.

**<u>Restructuring charge</u>** – The Company recorded restructuring charges related to various locations. These restructuring charges are excluded from management's assessment of the Company's operating performance. The Company believes the exclusion of the restructuring charges provides investors an enhanced view of the cost structure of the Company's operations and facilitates comparisons with the results of other periods that may not reflect such charges or may reflect different levels of such charges.

**<u>Gain of disposal of subsidiary</u>**– The Company excluded the gain on the disposal of a subsidiary. The Company believes this is not reflective of the ongoing operations and exclusion of this item provides investors an enhanced view of the Company's operating results.

**<u>Impairment of equity investment</u>**– The Company excluded the impairment on equity investment. The Company believes this is not reflective of the ongoing operations and exclusion of this item provides investors an enhanced view of the Company's operating results.

**<u>Non-cash mark-to-market investment adjustments</u>** – The Company excluded mark-to-market adjustments on various equity related investments. The Company believes this is not reflective of the ongoing operations and exclusion of this provides investors an enhanced view of the Company's operating results.

------

**<u>Officer retirement</u>** – The Company excluded costs related to the retirement of two executives. These costs represent cash payments and the accelerated vesting of previously issued stock awards. The Company feels it is appropriate to exclude these costs since they don't represent ongoing operating expenses and will present investors with a more accurate indication of our continuing operations.

**<u>CASH FLOW ITEMS</u>**

**<u>Free cash flow (FCF) (Non-GAAP)</u>**

FCF for the third quarter of 2025 is a non-GAAP financial measure, which is calculated by subtracting capital expenditures from cash flow from operations. For the third quarter of 2025, FCF was $62.8 million, which represents the cash and cash equivalents that we are able to generate after taking into account cash outlays required to maintain or expand property, plant and equipment. FCF is important because it allows us to pursue opportunities to develop new products, make acquisitions and reduce debt.

**<u>CONSOLIDATED RECONCILIATION OF NET INCOME TO EBITDA</u>**

EBITDA represents earnings before net interest expense, income tax provision, depreciation and amortization. Management believes EBITDA is useful to investors because it is frequently used by securities analysts, investors and other interested parties, such as financial institutions in extending credit, in evaluating companies in our industry and provides further clarity on our profitability. In addition, management uses EBITDA, along with other GAAP and non-GAAP measures, in evaluating our operating performance compared to that of other companies in our industry. The calculation of EBITDA generally eliminates the effects of financing, operating in different income tax jurisdictions, and accounting effects of capital spending, including the impact of our asset base, which can differ depending on the book value of assets and the accounting methods used to compute depreciation and amortization expense. EBITDA is not a recognized measurement under GAAP, and when analyzing our operating performance, investors should use EBITDA in addition to, and not as an alternative for, income from operations and net income, each as determined in accordance with GAAP. Because not all companies use identical calculations, our presentation of EBITDA may not be comparable to similarly titled measures used by other companies. For example, our EBITDA takes into account all net interest expense, income tax provision, depreciation and amortization without taking into account any amounts attributable to noncontrolling interest**.** Furthermore, EBITDA is not intended to be a measure of free cash flow for management's discretionary use, as it does not consider certain cash requirements such as tax and debt service payments.
