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

On May 7, 2026, Diodes Incorporated (the "Company") issued a press release announcing its first quarter ended March 31, 2026 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 May 7, 2026, are attached herewith as Exhibit 99.2 and Exhibit 99.3. Exhibit 99.2 provides an update focused on the Company's first quarter 2026 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 First Quarter 2026 Financial Results**

*1Q Revenue Increased over 20% and EPS Up over 100% YoY*

**Plano, Texas – May 7, 2026** -- Diodes Incorporated (Diodes) (Nasdaq: DIOD) today reported its financial results for the first quarter ended March 31, 2026.

**First Quarter Highlights**

• Revenue was $405.5 million, compared to $332.1 million in the first quarter 2025 and $391.6 million in the prior quarter;

• GAAP gross profit was $128.8 million, compared to $104.7 million in the first quarter 2025 and $121.9 million in the prior quarter;

• GAAP gross profit margin was 31.8 percent, compared to 31.5 percent in the first quarter 2025 and 31.1 percent in the prior quarter;

• GAAP net income was $15.0 million, compared to GAAP net loss of $4.4 million in the first quarter 2025 and GAAP net income of $10.2 million in the prior quarter;

• Non-GAAP adjusted net income was $19.8 million, compared to $8.8 million in the first quarter 2025 and $15.7 million in the prior quarter;

• GAAP EPS was $0.32 per diluted share, compared to GAAP loss per share of $0.10 per share in the same quarter a year ago and GAAP EPS of $0.22 per diluted share in the prior quarter;

• Non-GAAP EPS was $0.43 per diluted share, compared to $0.19 per diluted share in the first quarter 2025 and $0.34 per diluted share in the prior quarter;

• Excluding $6.0 million, net of tax, non-cash share-based compensation expense, both GAAP net income and non-GAAP adjusted net income would have increased by $0.13 per diluted share;

• EBITDA was $49.4 million, or 12.2 percent of revenue, compared to $26.2 million, or 7.9 percent of revenue in the same quarter a year ago and $41.9 million, or 10.7 percent of revenue in the prior quarter;

• Achieved $64.3 million cash flow from operations and $32.4 million of free cash flow, including $31.9 million of capital expenditures. Net cash flow was a positive $26.9 million.

Commenting on the results, Gary Yu, President and CEO of Diodes, stated, "Our first quarter revenue grew 22% year-over-year and an above-seasonal 3.5% sequentially, highlighting the solid demand recovery and momentum we are seeing across our key focus areas of automotive, industrial and AI-server related applications. In fact, this quarter is the fifth consecutive quarter of double-digit year-over-year growth and the highest percentage increase since the fourth quarter of 2021. Revenue in Europe led the growth as we continued to benefit from increased opportunities and orders from automotive customers as well as improved demand across broad industrial applications.

"Additionally, gross margin improved 70 basis points sequentially due mainly to the higher revenue contribution from the automotive and industrial markets, which totaled 44% of product revenue, combined with improving utilization. Notably, we delivered an over 100% year-over-year increase in quarterly earnings, clearly demonstrating the operating leverage in our model.

------

"After formally releasing our 3-year interim financial targets earlier this year, which includes reaching $2 billion in annual revenue, $700 million in gross profit and over $4.00 in non-GAAP EPS, this quarter was a great first step toward executing on these goals. Content expansion, design win momentum and new product introductions will continue to be the cornerstones of our growth initiatives, combined with increased manufacturing and cost efficiencies to further drive margin expansion."

**First Quarter 2026** 

Revenue for first quarter 2026 was $405.5 million, compared to $332.1 million in the first quarter 2025 and $391.6 million in the prior quarter.

GAAP gross profit for the first quarter 2026 was $128.8 million, or 31.8 percent of revenue, compared to $104.7 million, or 31.5 percent of revenue, in the first quarter 2025 and $121.9 million, or 31.1 percent of revenue, in the prior quarter.

GAAP operating expenses for first quarter 2026 were $109.0 million, or 26.9 percent of revenue, and on a non-GAAP basis were $103.9 million, or 25.6 percent of revenue, which excludes $3.9 million acquisition-related intangible asset cost and $1.1 million of board/officer retirement expense. GAAP operating expenses in the first quarter 2025 were $103.4 million, or 31.1 percent of revenue and $108.7 million, or 27.8 percent of revenue, in the fourth quarter 2025.

First quarter 2026 GAAP net income was $15.0 million, or $0.32 per diluted share, compared to GAAP net loss in the first quarter 2025 of $4.4 million, or a loss of $0.10 per diluted share and GAAP net income in the prior quarter of $10.2 million, or $0.22 per diluted share.

First quarter 2026 non-GAAP adjusted net income was $19.8 million, or $0.43 per diluted share, which excluded, net of tax, $3.2 million of acquisition-related intangible asset amortization cost, $0.9 million of board/officer retirement expense and $0.7 million of loss on investments. This compares to non-GAAP adjusted net income of $8.8 million, or $0.19 per diluted share, in the first quarter 2025 and $15.7 million, or $0.34 per diluted share, in the prior quarter.

Note: Throughout this release, we refer to "net income/loss attributable to common stockholders" as "net income/loss."

(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 first quarter 2026 GAAP and non-GAAP adjusted net income was approximately $6.0 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 $0.13 per share for the first quarter 2026, compared to $0.11 for the first quarter 2025 and $0.12 per share in the prior quarter.

EBITDA (a non-GAAP measure), which represents earnings before net interest expense, income tax, depreciation and amortization, in the first quarter 2026 was $49.4 million, or 12.2 percent of revenue, compared to $26.2 million, or 7.9 percent of revenue, in the first quarter 2025 and $41.9 million, or 10.7 percent of revenue, in the prior quarter. For a reconciliation of GAAP net income to EBITDA, see the table near the end of this release for further details.

For the first quarter 2026, net cash provided by operating activities was $64.3 million. Net cash flow was positive $26.9 million. Free cash flow (a non-GAAP measure) was $32.4 million, which includes $31.9 million of capital expenditures.

**Balance Sheet** 

As of March 31, 2026, the Company had approximately $409 million in cash and cash equivalents, restricted cash, and short-term investments. Total debt (including long-term and short-term) amounted to approximately $55 million and working capital was approximately $891 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 March 31, 2026.

**Business Outlook** 

Gary Yu further commented, "For the second quarter of 2026, we expect revenue to be approximately $435 million, plus or minus 3 percent, representing an 18.8 percent increase year-over-year and a 7.3 percent increase sequentially at the mid-point. This quarter will be the sixth consecutive quarter of double-digit year-over-year growth and another above seasonal sequential growth quarter. GAAP gross margin is expected to be 32.8 percent, plus or minus 1 percent. Non-GAAP adjusted EPS is expected to be $0.60, plus or minus $0.10."

A reconciliation of our forward-looking non-GAAP EPS to the most directly comparable GAAP measures is not provided because such items cannot be reasonably calculated without unreasonable efforts due to the unpredictability of the amounts and timing of events affecting the items we exclude, including acquisition-related intangible asset costs, board member/officer retirements, acquisition-related costs, restructuring costs, gain/loss on investment, non-cash mark-to-market investment adjustments, impairment of equity investment, and other charges.

------

**<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 / Officer retirement</u>** – The Company excluded costs related to (1) the retirement of a board member, these costs represent cash payments and the accelerated vesting of previously issued stock awards, (2) the retirement of an officer, 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>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/Loss on Investment</u>** – The Company excluded gains and losses on various investments. The Company believes these amounts are not reflective on the ongoing operations of the Company and exclusion of these items, 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>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>CASH FLOW ITEMS</u>**

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

FCF for the first quarter of 2026 is a non-GAAP financial measure, which is calculated by subtracting capital expenditures from cash flow from operations. For the first quarter of 2026, FCF was $32.4 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.

The following table provides a reconciliation of net income to EBITDA *(in thousands, unaudited):*
