•

Cash flow used in operations of $31.1 million and a negative $51.5 million of free cash flow, including $20.4 of capital expenditures. Net cash flow was a negative $47.9 million.

Commenting on the results, Gary Yu, President of Diodes, stated, “Revenue in the quarter reflected the slower than expected recovery in the consumer, computing and communications markets coupled with typical first quarter seasonality due to the Chinese New Year holiday. However, late in the quarter we began to see some signs of demand improvement with distributor inventory levels starting to stabilize, supporting our belief that the first quarter should be the low point and are guiding for a return to seasonal growth in the second quarter.

“In the automotive and industrial end markets, first quarter combined product revenue remained above our target model of 40% but continues to be affected by inventory adjustments and softness in certain areas. More broadly, the slower overall demand environment in the quarter contributed to reduced loading at our manufacturing facilities both internal production as well as from our manufacturing service agreements, temporarily impacting gross margin. We expect gross margin to resume toward our target of 40% as we increase our factory loading by qualifying more products combined with increasing revenue

growth from our higher-margin automotive and industrial markets, consistent with our historical performance and long-term growth strategy.

“In summary, with early evidence of recent pricing pressures subsiding, Diodes is well positioned with the size and scale to support a return to growth as global demand and distributor inventory improves across our end markets. We remain focused on operating our manufacturing facilities at a high level of efficiency as demonstrated by the steps the Company has taken over the past several quarters to further develop our process technology and capabilities, while lowering manufacturing costs across our operations.”

Revenue for first quarter 2024 was $302.0 million, compared to $322.7 million in the fourth quarter 2023 and $467.2 million in the first quarter 2023.

GAAP gross profit for the first quarter 2024 was $99.6 million, or 33.0 percent of revenue, compared to $112.5 million, or 34.9 percent of revenue, in the fourth quarter 2023 and $194.5 million, or 41.6 percent of revenue, in the first quarter of 2023.

GAAP operating expenses for first quarter 2024 were $86.6 million, or 28.7 percent of revenue, and on a non-GAAP basis were $87.6 million, or 29.0 percent of revenue, which excludes $3.8 million amortization of acquisition-related intangible asset expenses and $4.8 million insurance recovery for a manufacturing facility. GAAP operating expenses in the fourth quarter 2023 were $91.8 million, or 28.4 percent of revenue and in the first quarter 2023 were $108.0 million, or 23.1 percent of revenue.

First quarter 2024 GAAP net income was $14.0 million, or $0.30 per diluted share, compared to GAAP net income in the fourth quarter 2023 of $25.3 million, or $0.55 per diluted share, and $71.2 million, or $1.54 per diluted share, of GAAP net income in the first quarter 2023.

First quarter 2024 non-GAAP adjusted net income was $13.0 million, or $0.28 per diluted share, which excluded, net of tax, $3.8 million insurance recovery for a manufacturing facility, $3.1 million of acquisition-related intangible asset costs and $0.3 million non-cash mark-to-market investment value adjustment. This compares to non-GAAP adjusted net income of $23.4 million, or $0.51 per diluted share, in the fourth quarter 2023 and $73.4 million, or $1.59 per diluted share, in the first quarter 2023.

The following is an unaudited summary reconciliation of GAAP net income to non-GAAP adjusted net income and per share data, net of tax (in thousands, except per share data):

Note: Throughout this release, we refer to “net income attributable to common stockholders” as “net income.”

(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 2024 GAAP net income and non-GAAP adjusted net income was approximately $4.0 million, net of tax, of non-cash share-based compensation expense. Excluding share-based compensation expense, both GAAP earnings per share (“EPS”) and non-GAAP adjusted EPS would have increased by $0.09 per diluted share for the first quarter 2024, $0.13 for the fourth quarter 2023 and $0.17 for first quarter 2023.

EBITDA (a non-GAAP measure), which represents earnings before net interest expense, income tax, depreciation and amortization, in first quarter 2024 was $48.3 million, or 16.0 percent of revenue, compared to $58.4 million, or 18.1 percent of revenue, in fourth quarter 2023 and $121.8 million, or 26.1 percent of revenue, in first quarter 2023. For a reconciliation of GAAP net income to EBITDA, see the table near the end of this release for further details.

For first quarter 2024, net cash used in operating activities was $31.1 million. Net cash flow was a negative $47.9 million. Free cash flow (a non-GAAP measure) was a negative $51.5 million, which includes $20.4 million of capital expenditures.

As of March 31, 2024, the Company had approximately $280 million in cash and cash equivalents, restricted cash, and short-term investments. Total debt (including long-term and short-term) amounted to approximately $70 million and working capital was approximately $824 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, 2024.

Gary Yu further commented, “For the second quarter of 2024, we expect revenue to be approximately $316 million, plus or minus 3 percent, representing a 4.6% sequential increase at the mid-point and reflecting a return to typical seasonal growth. GAAP gross margin is expected to be 33.5 percent, plus or minus 1 percent, reflecting the lower mix of revenue from the automotive and industrial markets as the 3C markets recover. Non-GAAP operating expenses, which are GAAP operating expenses adjusted for amortization of acquisition-related intangible assets, are expected to be approximately 28.5 percent of revenue, plus or minus 1 percent. We expect net interest income to be approximately $3.0 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 second quarter are anticipated to be approximately 46.5 million.”

Amortization of acquisition-related intangible assets of $3.1 million, after tax, for previous acquisitions is not included in these non-GAAP estimates.

Note: Throughout this release, we refer to “net income attributable to common stockholders” as “net income.”

Note: Included in GAAP and non-GAAP net income was approximately $4.0 million, net of tax, non-cash share-based compensation expense. Excluding share-based compensation expense, both GAAP and non-GAAP diluted earnings per share would have improved by $0.09 per share.

Note: Included in GAAP and non-GAAP adjusted net income was approximately $7.7 million, net of tax, non-cash share-based compensation expense. Excluding share-based compensation expense, both GAAP and non-GAAP adjusted diluted earnings per share would have improved by $0.17 per share.

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:

Amortization of acquisition-related intangible assets – 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.

Officer retirement – 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.

Insurance recovery for manufacturing facility – 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.

Non-cash mark-to-market investment adjustments – 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.

FCF for the first quarter of 2024 is a non-GAAP financial measure, which is calculated by subtracting capital expenditures from cash flow from operations. For the first quarter of 2024, FCF was a negative $51.5 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.

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.
