ANDOVER, Mass., Feb. 07, 2024 (GLOBE NEWSWIRE) -- MKS Instruments, Inc. (NASDAQ:MKSI), a global provider of enabling technologies that transform our world, today reported fourth quarter and full year 2023 financial results.

"We closed the year on a solid note with revenue and Adjusted EBITDA exceeding the high-end of our guidance range," said John T.C. Lee, President and Chief Executive Officer.

Mr. Lee added, "We believe our broad portfolio of proprietary and foundational solutions puts us in pole position to capture a wide array of opportunities when end market conditions improve, setting the stage for attractive shareholder value creation in the years to come."

"In 2023, we executed on all the levers under our control, including factory efficiency, operating expense management, lowering our tax rate, and proactive management of our debt, including successfully completing a repricing and allocating more than 80% of our free cash flow for debt paydown," said Seth H. Bagshaw, Executive Vice President and Chief Financial Officer. "In addition, in the last month, we successfully completed a refinancing of our term loan A and made a voluntary debt prepayment of $50 million."

Use of Non-GAAP Financial Results

This press release includes financial measures that are not in accordance with U.S. generally accepted accounting principles ("Non-GAAP financial measures"). These Non-GAAP financial measures should be viewed in addition to, and not as a substitute for, MKS' reported results under U.S. generally accepted accounting principles ("GAAP"), and may be different from Non-GAAP financial measures used by other companies. In addition, these Non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles. MKS management believes the presentation of these Non-GAAP financial measures is useful to investors for comparing prior periods and analyzing ongoing business trends and operating results.

MKS is not providing a quantitative reconciliation of forward-looking Non-GAAP net earnings per diluted share and Adjusted EBITDA to their most directly comparable GAAP financial measures because it is unable to estimate with reasonable certainty the ultimate timing or amount of certain significant items without unreasonable efforts. These items include, but are not limited to, acquisition and integration costs, amortization of intangible assets, ransomware remediation costs, restructuring expense, goodwill and intangible asset impairments, excess and obsolescence inventory charges, amortization of debt issuance costs, debt refinancing fee, loss on extinguishment of debt, and the income tax effect of these items. These items are uncertain, depend on various factors, including, but not limited to, our acquisition of Atotech Limited ("Atotech") in August 2022 (the "Atotech Acquisition"), the timing of ransomware remediation, and the interest rate and refinancing environment, and could have a material impact on GAAP reported results for the relevant period.

For further information regarding these Non-GAAP financial measures, including a change to how MKS defines Adjusted EBITDA, please refer to the tables presenting reconciliations of our Non-GAAP results to our GAAP results and the "Notes on Our Non-GAAP Financial Information" at the end of this press release.

SAFE HARBOR FOR FORWARD-LOOKING STATEMENTS

This press release contains "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 regarding the future financial performance, business prospects and growth of MKS Instruments, Inc. ("MKS", the "Company", "our", or "we"). These statements are only predictions based on current assumptions and expectations. Any statements that are not statements of historical fact (including statements containing the words "will," "projects," "intends," "believes," "plans," "anticipates," "expects," "estimates," "forecasts," "continues" and similar expressions) should be considered to be forward-looking statements. Actual events or results may differ materially from those in the forward-looking statements set forth herein. Among the important factors that could cause actual events to differ materially from those in the forward-looking statements that we make are the need to generate sufficient cash flows to service and repay the substantial indebtedness we incurred in connection with the Atotech Acquisition; the terms of our existing credit facilities under which we incurred such debt; our entry into the chemicals technology business through the Atotech Acquisition, in which we did not have previous experience and which may expose us to significant additional liabilities; the risk that we are unable to integrate the Atotech Acquisition successfully or realize the anticipated synergies, cost savings and other benefits of the Atotech Acquisition; legal, reputational, financial and contractual risks resulting from the ransomware incident we identified in February 2023, and other risks related to cybersecurity, data privacy and intellectual property; competition from larger, more advanced or more established companies in our markets; the ability to successfully grow our business and the businesses of Atotech and Electro Scientific Industries, Inc., which we acquired in February 2019, and financial risks associated with those and potential future acquisitions, including goodwill and intangible asset impairments; manufacturing and sourcing risks, including those associated with limited and sole source suppliers and the impact and duration of supply chain disruptions, component shortages, and price increases; changes in global demand and the impact of COVID-19 or any other widespread health crises, including with respect to such supply chain disruptions, component shortages and price increases; risks associated with doing business internationally, including geopolitical conflicts, such as the Israel-Hamas war, trade compliance, regulatory restrictions on our products, components or markets, particularly the semiconductor market, and unfavorable currency exchange and tax rate fluctuations, which risks become more significant as we grow our business internationally and in China specifically; conditions affecting the markets in which we operate, including fluctuations in capital spending in the semiconductor, electronics manufacturing and automotive industries, and fluctuations in sales to our major customers; disruptions or delays from third-party service providers upon which our operations may rely; the ability to anticipate and meet customer demand; the challenges, risks and costs involved with integrating or transitioning global operations of the companies we have acquired; risks associated with the attraction and retention of key personnel; potential fluctuations in quarterly results; dependence on new product development; rapid technological and market change; acquisition strategy; volatility of stock price; risks associated with chemical manufacturing and environmental regulation compliance; risks related to defective products; financial and legal risk management; and the other important factors described in MKS' Annual Report on Form 10-K for the year ended December 31, 2022 and any subsequent Quarterly Reports on Form 10-Q, as filed with the U.S. Securities and Exchange Commission. MKS is under no obligation to, and expressly disclaims any obligation to, update or alter these forward-looking statements, whether as a result of new information, future events or otherwise after the date of this press release. Amounts reported in this press release are preliminary and subject to finalization prior to the filing of our Annual Report on Form 10-K for the year ended December 31, 2023.

Notes on Our Non-GAAP Financial Information

Non-GAAP financial measures adjust GAAP financial measures for the items listed below. These Non-GAAP financial measures should be viewed in addition to, and not as a substitute for, MKS' reported GAAP results, and may be different from Non-GAAP financial measures used by other companies. In addition, these Non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles. MKS management believes the presentation of these Non-GAAP financial measures is useful to investors for comparing prior periods and analyzing ongoing business trends and operating results. Totals presented may not sum and percentages may not recalculate using figures presented due to rounding.

Note 1: We recorded an excess and obsolescence inventory charge related to a product line that is being discontinued.

Note 2: Costs of revenues included the amortization from the step-up of inventory to fair value as a result of the Atotech Acquisition.

Note 3: Acquisition and integration costs primarily related to the Atotech Acquisition.

Note 4: Restructuring costs during the three and twelve months ended December 31, 2023 and the three months ended September 30, 2023, primarily related to severance costs due to global cost-saving initiatives. Restructuring costs during the three months ended December 31, 2022 primarily related to the closure of two facilities in Europe and movement of certain products to low cost regions. Restructuring costs during the twelve months ended December 31, 2022 primarily related to executive payments made related to the Atotech Acquisition, severance costs due to a global cost-saving initiative, the closure of two facilities in Europe and movement of certain products to low cost regions.

Note 5: During the three months ended June 30, 2023, we noted softer industry demand, particularly in the personal computer and smartphone markets and concluded there was a triggering event at our Materials Solutions Division, which represents the former Atotech business, and Equipment Solutions Business, which represents the former Electro Scientific Industries business and is a reporting unit of our Photonics Solutions Division. We performed a quantitative assessment which resulted in an impairment of $1.3 billion for our Materials Solutions Division and $0.5 billion for our Equipment Solutions Business. In addition, during the three months ended December 31, 2023, as part of our annual goodwill and intangible asset impairment analysis, we recorded additional impairment charges of $62 million for our Materials Solutions Division and $13 million for our Equipment Solutions Business.

Note 6: We recorded a gain on the sale of a minority interest investment in a private company.

Note 7: We recorded additional interest expense related to the amortization of debt issuance costs associated with our term loan facility.

Note 8: We recorded fees and expenses related to the repricing of the USD term loan B under our term loan facility.

Note 9: We recorded costs, net of recoveries, associated with the ransomware incident we identified on February 3, 2023. These costs were primarily comprised of various third-party consulting services, including forensic experts, restoration experts, legal counsel, and other information technology and accounting professional expenses, enhancements to our cybersecurity measures, and costs to restore our systems and access our data.

Note 10: We recorded a charge to write-off deferred financing fees and original issue discount costs related to the repricing of the USD term loan B under our term loan facility.

Note 11: We realized a gain from a euro currency contract used to hedge our financing in connection with the Atotech Acquisition. The contract expired on January 31, 2022.

Note 12: We no longer intend to indefinitely reinvest earnings of our foreign subsidiaries after the Atotech Acquisition. Additional income tax expense was recorded to reflect an estimate of withholding taxes that would be due on repatriation of prior period earnings.

Note 13: Non-GAAP adjustments are tax effected at applicable statutory rates resulting in a difference between the GAAP and Non-GAAP tax rates.

Note 14: In the fourth quarter of 2023, we modified our definition of Adjusted EBITDA to exclude other expense, net from this Non-GAAP measure. Other expense, net primarily relates to changes in foreign exchange rates. We believe this change enhances investor insight into our operational performance. We have applied this modified definition of Adjusted EBITDA to all periods presented.
