Commenting on the results, Dr. Keh-Shew Lu, Chairman, President and Chief Executive Officer, stated, “In spite of the COVID-related lockdowns and power outages throughout the year in China as well as the global economic slowdown, we delivered 10.8% annual growth over 2021 and achieved record financial performance across all metrics. In fact, the fourth quarter represented our ninth consecutive quarter of year-over-year growth. Additionally, our earnings power and cash generation in 2022 were also significant highlights with gross margin expanding 420 basis points to 41.3%, operating margin expanding 510 basis points to 20.4%, and GAAP EPS increasing 44% to $7.20 and non-GAAP EPS growing 42% to $7.36. We also achieved record cash flow from operations of $393 million.

“Underpinning the Company’s noteworthy performance was continued strong growth in our automotive end market, which increased 40% over 2021 and reached 15% of product revenue for the year. We also continued to drive growth in our industrial end market through our ongoing content expansion efforts, which contributed to our industrial and automotive end markets representing 42% of 2022 product revenue and exceeding our target model of 40%. The growth in these end markets combined with the ongoing increase of our Pericom products also contributed to our strong gross margin expansion throughout the year as part of our product mix improvement efforts.”

Dr. Lu concluded by stating, “Reaching the $2 billion revenue level in 2022 was a significant and meaningful achievement for the entire Diodes team. With gross profit growing 23% to $827 million for the year, we have taken another giant step towards the next goal in our 2025 financial targets to achieve $1 billion in annual gross profit. I am very proud of our accomplishments and our ability to consistently deliver both top line growth and significantly expanded earnings for our shareholders.”

Revenue for fourth quarter 2022 was $496.2 million, increasing 3.3 percent from $480.2 million in the fourth quarter 2021 and down 4.8 percent from $521.3 million in the third quarter 2022, which is slightly better than typical seasonality.

GAAP gross profit for the fourth quarter 2022 was $206.2 million, or 41.6 percent of revenue, increasing from $190.7 million, or 39.7 percent of revenue, in the fourth quarter of 2021 and down from $217.8 million, or 41.8 percent of revenue, in the third quarter 2022.

GAAP operating expenses for fourth quarter 2022 were $109.7 million, or 22.1 percent of revenue, and on a non-GAAP basis were $105.9 million, or 21.3 percent of revenue, which excludes $3.8 million of amortization of acquisition-related intangible asset expenses. GAAP operating expenses in the fourth quarter 2021 were $104.7 million, or 21.8 percent of revenue, and in the third quarter 2022 were $105.4 million, or 20.2 percent of revenue.

Fourth quarter 2022 GAAP net income was $92.1 million, or $2.00 per diluted share, compared to GAAP net income in the fourth quarter 2021 of $65.5 million, or $1.43 per diluted share, and GAAP net income of $86.4 million, or $1.88 per diluted share, in the third quarter 2022.

Fourth quarter 2022 non-GAAP adjusted net income was $79.6 million, or $1.73 per diluted share, which excluded, net of tax, $3.1 million of acquisition-related intangible asset costs. This compares to non-GAAP adjusted net income of $73.3 million, or $1.60 per diluted share, in the fourth quarter 2021 and $92.2 million, or $2.00 per diluted share, in the third quarter 2022.

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 fourth quarter 2022 GAAP net income and non-GAAP adjusted net income was approximately $7.6 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 $0.16 per diluted share for the fourth quarter 2022, $0.14 for fourth quarter 2021 and $0.18 for the third quarter 2022.

EBITDA (a non-GAAP measure), which represents earnings before net interest expense, income tax, depreciation and amortization, in fourth quarter 2022 was $129.6 million, or 26.1 percent of revenue, increasing from $139.0 million, or 28.9 percent of revenue, in fourth quarter 2021 and a decrease from the $141.9 million, or 27.2 percent of revenue, in third quarter 2022. For a reconciliation of GAAP net income to EBITDA, see the table near the end of this release for further details.

For fourth quarter 2022, net cash provided by operating activities was $102.9 million. Net cash flow was a negative $44.7 million, which includes the pay down of $114.1 million of total debt. Free cash flow (a non-GAAP measure) was $39.1 million, which includes $63.8 million of capital expenditures.

As of December 31, 2022, the Company had approximately $348 million in cash and cash equivalents, restricted cash, and short-term investments. Total debt (including long-term and short-term) amounted to approximately $186 million and working capital was approximately $729 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-K for the year ending December 31, 2022.

Dr. Lu concluded, “For the first quarter of 2023, we expect revenue to be approximately $467 million, plus or minus 3 percent. GAAP gross margin is expected to be 41.0 percent, plus or minus 1 percent. Even with the revenue and loading decrease in the first quarter, we expect to maintain our gross margin effectively comparable to last quarter and above our target model of 40 percent. Non-GAAP operating expenses, which are GAAP operating expenses adjusted for amortization of acquisition-related intangible assets, are expected to be approximately 22.2 percent of revenue, plus or minus 1 percent. We expect net interest expense to be approximately $2.5 million. Our income tax rate is expected to be 19.0 percent, plus or minus 3 percent, and shares used to calculate diluted EPS for the first 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 $7.6 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 $0.16 per share.

Note: Included in GAAP and non-GAAP adjusted net income was approximately $6.5 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 $0.14 per share.

Note: Included in GAAP and non-GAAP adjusted net income was approximately $28.7 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 $0.62 per share.

Note: Included in GAAP and non-GAAP adjusted net income was approximately $26.2 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 $0.57 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.

Acquisition related costs – 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.

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.

Gain/Loss on sale of manufacturing facilities - The Company sold a manufacturing subsidiary and as part of the transaction, there are working capital adjustments that are recorded as gains or losses in the statement of operations. 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.

Non-cash mark-to-market investment adjustments – The Company excluded market-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.

Restructuring costs – The Company recorded restructuring charges related to various international 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.

LSC investments related – The Company excluded market to market adjustments and the associated tax on certain LSC equity investments. The Company has also excluded certain taxes related to integration and restructuring activities within certain Taiwan subsidiaries including LSC. 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 fourth quarter of 2022 is a non-GAAP financial measure, which is calculated by subtracting capital expenditures from cash flow from operations. For the fourth quarter of 2022, FCF was $39.1 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.
