NORTH READING, Mass., Oct. 26, 2021 (GLOBE NEWSWIRE) -- Teradyne, Inc. (NASDAQ:TER) reported revenue of $951 million for the third quarter of 2021 of which $688 million was in Semiconductor Test, $103 million in System Test, $69 million in Wireless Test and $91 million in Industrial Automation (IA). GAAP net income for the third quarter was $256.7 million or $1.41 per diluted share. On a non-GAAP basis, Teradyne's net income in the third quarter was $278.6 million, or $1.59 per diluted share, which excluded losses on convertible debt conversions, acquired intangible asset amortization, restructuring and other charges, non-cash convertible debt interest, discrete tax adjustments and included the related tax impact on non-GAAP adjustments.

"Demand for both our Test and Industrial Automation products remained strong in Q3 and we delivered our eighth consecutive quarter of double-digit, year on year revenue and profit growth," said Teradyne CEO and President Mark Jagiela. "Higher than expected test shipments balanced lower than planned shipments from our Industrial Automation businesses as we encountered supply constraints in those product lines in the quarter."

"Q4'21 sales are expected to increase over 10% from Q4 2020's record level on growing demand in Industrial/Automotive Test, Storage Test, and Industrial Automation. Full year company sales, GAAP EPS and non-GAAP EPS are expected to grow 18%, 28% and 27%, respectively, at the mid-point of our guidance."

Guidance for the fourth quarter of 2021 is revenue of $820 million to $900 million, with GAAP net income of $1.08 to $1.33 per diluted share and non-GAAP net income of $1.14 to $1.40 per diluted share. Non-GAAP guidance excludes acquired intangible asset amortization, non-cash convertible debt interest and includes the related tax impact on non-GAAP adjustments.

Non-GAAP Results

In addition to disclosing results that are determined in accordance with GAAP, Teradyne also discloses non-GAAP results of operations that exclude certain income items and charges. These results are provided as a complement to results provided in accordance with GAAP. Non-GAAP income from operations and non-GAAP net income exclude losses on convertible debt conversions, acquired intangible assets amortization, non-cash convertible debt interest, pension actuarial gains and losses, discrete income tax adjustments, fair value inventory step-up, and restructuring and other, and includes the related tax impact on non-GAAP adjustments. GAAP requires that these items be included in determining income from operations and net income. Non-GAAP income from operations, non-GAAP net income, non-GAAP income from operations as a percentage of revenue, non-GAAP net income as a percentage of revenue, and non-GAAP net income per share are non-GAAP performance measures presented to provide meaningful supplemental information regarding Teradyne's baseline performance before gains, losses or other charges that may not be indicative of Teradyne's current core business or future outlook. These non-GAAP performance measures are used to make operational decisions, to determine employee compensation, to forecast future operational results, and for comparison with Teradyne's business plan, historical operating results and the operating results of Teradyne's competitors. Non-GAAP gross margin excludes fair value inventory step-up. GAAP requires that this item be included in determining gross margin. Non-GAAP gross margin dollar amount and percentage are non-GAAP performance measures that management believes provide useful supplemental information for management and the investor. Management uses non-GAAP gross margin as a performance measure for Teradyne's current core business and future outlook and for comparison with Teradyne's business plan, historical gross margin results and the gross margin results of Teradyne's competitors. Non-GAAP diluted shares include the impact of Teradyne's call option on its shares. Management believes each of these non-GAAP performance measures provides useful supplemental information for investors, allowing greater transparency to the information used by management in its operational decision making and in the review of Teradyne's financial and operational performance, as well as facilitating meaningful comparisons of Teradyne's results in the current period compared with those in prior and future periods.

Safe Harbor Statement

This release contains forward-looking statements regarding Teradyne's future business prospects, the impact of the COVID-19 pandemic, results of operations, market conditions, earnings per share, the payment of a quarterly dividend, the repurchase of Teradyne common stock pursuant to a share repurchase program, and the impact of U.S. and Chinese export and tariff laws. Such statements are based on the current assumptions and expectations of Teradyne's management and are neither promises nor guarantees of future performance, events, earnings per share, use of cash, payment of dividends, repurchases of common stock, payment of the senior convertible notes, the impact of the COVID-19 pandemic, or the impact of U.S. and Chinese export and tariff laws. There can be no assurance that management's estimates of Teradyne's future results or other forward-looking statements will be achieved. Additionally, the current dividend and share repurchase programs may be modified, suspended or discontinued at any time.

On May 16, 2019, Huawei and 68 of its affiliates, including HiSilicon, were added to the U.S. Department of Commerce Entity List under U.S. Export Administration Regulations (the "EAR"). This action by the U.S. Department of Commerce imposed new export licensing requirements on exports, re-exports, and in-country transfers of all U.S. - regulated products, software and technology to the designated Huawei entities. While most of Teradyne's products are not subject to the EAR and therefore were not affected by the Entity List restrictions, some of its products are currently manufactured in the U.S. and thus subject to the Entity List restrictions.

On August 17, 2020, the U.S. Department of Commerce published final regulations expanding the scope of the U.S. EAR to include additional products that became subject to export restrictions relating to Huawei entities including HiSilicon. These new regulations restrict the sale to Huawei and the designated Huawei entities of certain non-U.S. made items, such as semiconductor devices, manufactured for or sold to Huawei entities including HiSilicon under specific, detailed conditions set forth in the new regulations. These new regulations have impacted our sales to Huawei, HiSilicon and their suppliers. Teradyne is taking appropriate actions, including filing for licenses with the U.S. Department of Commerce. However, Teradyne cannot be certain that the actions it takes will mitigate the risks associated with the new export controls that impact its business. It is uncertain the extent these new regulations and any other additional regulations that may be implemented by the U.S. Department of Commerce or other government agency may have on Teradyne's business and financial results.

On April 28, 2020, the U.S. Department of Commerce published new export control regulations for certain U.S. products and technology sold to military end users or for military end-use in China, Russia and Venezuela. The definition of military end user is broad. The regulations went into effect on June 29, 2020. In December 2020, the U.S. Department of Commerce issued a list of companies in China and other countries that it considered to be military end users. Teradyne does not expect that compliance with the new export controls will significantly impact its ability to sell products to its customers in China or to manufacture products in China. The new export controls, however, could disrupt the Company's supply chain, increase compliance costs and impact the demand for the Company's products in China and, thus, have a material adverse impact on Teradyne's business, financial condition or results of operations. In addition, while the Company maintains an export compliance program, its compliance controls could be circumvented, exposing the Company to legal liabilities. Teradyne continues to assess the impact of the new export controls on its business and operations and take appropriate actions, including filing for licenses with the U.S. Department of Commerce, to minimize any disruption. However, Teradyne cannot be certain that the actions it takes will mitigate all the risks associated with the new export controls that may impact its business.

In response to the regulations issued by the U.S. Department of Commerce, the Chinese government has passed new laws that may impact Teradyne's business activities in China. The Company is assessing the potential impact of these new Chinese laws and monitoring relevant laws and regulations issued by the Chinese government.

The global pandemic of the novel strain of the coronavirus (COVID-19) has resulted in authorities implementing numerous measures to try to contain the virus, such as travel bans and restrictions, quarantines, shelter in place orders, shutdowns, and vaccination mandates. These measures have impacted and may further impact Teradyne's workforce and operations, the operations of its customers, and those of its contract manufacturers and suppliers. Most recently, on September 9, 2021, President Biden issued Executive Order 14042 requiring covered employees of certain Federal contractors and subcontractors to be "fully vaccinated," unless legally entitled to an accommodation due to a disability or religious belief, practice, or observance. Additionally, on September 9, 2021, President Biden announced that he has directed the Occupational Safety and Health Administration (OSHA) to develop a rule mandating vaccination or weekly testing for employers with 100+ employees. As Teradyne implements measures to comply with these new regulations, the Company may experience increased compliance costs, increased risk of non-compliance and increased risk of employee attrition.

The COVID-19 pandemic has adversely impacted the Company's results of operations, including increased costs company-wide. The Company cannot accurately estimate the amount of the impact on Teradyne's 2021 financial results and to its future financial results. The COVID-19 outbreak has significantly increased economic and demand uncertainty in Teradyne's markets. This uncertainty resulted in a significant decrease in demand for certain Teradyne products and could continue to impact demand for an uncertain period of time. The spread of COVID-19 has caused Teradyne to modify its business practices (including employee travel, employees working remotely, and cancellation of physical participation in meetings, events and conferences) and the Company may take further actions as may be required by government authorities or that it determines are in the best interests of its employees, customers, contract manufacturers and suppliers. There is uncertainty that such measures will be sufficient to mitigate the risks posed by the virus, and Teradyne's ability to perform critical functions could be impacted. The degree to which COVID-19 impacts Teradyne's results will depend on future developments, which are highly uncertain and cannot be predicted, including, but not limited to, the duration of the virus, its severity, the actions to contain the virus or the availability and impact of vaccines in countries where the Company does business, and how quickly and to what extent normal economic and operating conditions can resume.

Important factors that could cause actual results, earnings per share, use of cash, dividend payments, repurchases of common stock, or payment of the senior convertible notes to differ materially from those presently expected include: conditions affecting the markets in which Teradyne operates; decreased or delayed product demand from one or more significant customers; development, delivery and acceptance of new products; the ability to grow the Industrial Automation business; increased research and development spending; deterioration of Teradyne's financial condition; the continued impact of the COVID-19 pandemic and related government responses on the market and demand for Teradyne's products, on its contract manufacturers and supply chain, and on its workforce; the impact of the global semiconductor supply shortage on our supply chain and contract manufacturers; the consummation and success of any mergers or acquisitions; unexpected cash needs; insufficient cash flow to make required payments and pay the principal amount on the senior convertible notes; the business judgment of the board of directors that a declaration of a dividend or the repurchase of common stock is not in the company's best interests; additional U.S. tax regulations or IRS guidance; the impact of any tariffs or export controls imposed in the U.S. or China; compliance with trade protection measures or export restrictions; the impact of U.S. Department of Commerce or other government agency regulations relating to Huawei and HiSilicon; and other events, factors and risks disclosed in filings with the SEC, including, but not limited to, the "Risk Factors" sections of Teradyne's Annual Report on Form 10-K for the fiscal year ended December 31, 2020 and Quarterly Report on Form 10-Q for the fiscal quarter ended July 4, 2021. The forward-looking statements provided by Teradyne in this press release represent management's views as of the date of this release. Teradyne anticipates that subsequent events and developments may cause management's views to change. However, while Teradyne may elect to update these forward-looking statements at some point in the future, Teradyne specifically disclaims any obligation to do so. These forward-looking statements should not be relied upon as representing Teradyne's views as of any date subsequent to the date of this release.
