Quarterly revenue of $887 million, at the high end of guidance
Quarterly GAAP net income of $23 million and net income per share of $0.33
Quarterly Adjusted EBITDA of $228 million and Non-GAAP net earnings per diluted share of $1.53, exceeding the high-end of guidance

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

"Our continued execution, especially in our Semiconductor and Electronics & Packaging markets, drove strong financial results in the second quarter. Revenues of $887 million were at the high end of our guidance while Adjusted EBITDA exceeded the upper end of that same guidance," said John T.C. Lee, President and Chief Executive Officer. "As a critical enabler of chipmaking, package substrates and printed circuit boards, we have been able to leverage our broad and differentiated product portfolio and commitment to prudent cost control to generate healthy profits, even in a muted semiconductor and advanced electronics environment."

Mr. Lee added, "The team continues to deliver robust gross margins as we closely manage the cost structure through the current cycle. In addition, we have taken proactive measures to improve our debt profile, including our convertible notes offering in May as well as another repricing and voluntary term loan prepayment of $110 million in July. These actions set the stage for improved operating and earnings leverage when demand conditions recover."

Third Quarter 2024 Outlook

For the third quarter of 2024, the Company expects revenue of $870 million, plus or minus $40 million, Adjusted EBITDA of $206 million, plus or minus $23 million, and Non-GAAP net earnings per diluted share of $1.43, plus or minus $0.28.

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 we are 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, 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, the integration of our acquisition of Atotech Limited ("Atotech"), which we acquired in August 2022 (the "Atotech Acquisition"), 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 in the fourth quarter of 2023 to the definition of 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.

Additional Financial Information

At June 30, 2024, the Company had $851 million in cash, cash equivalents and short-term investments, $3.6 billion of secured term loan principal outstanding, $1.4 billion of convertible senior notes outstanding and up to $675 million of additional borrowing capacity under a revolving credit facility, subject to certain leverage ratio requirements. During the second quarter of 2024, the Company paid a cash dividend of $15 million or $0.22 per diluted share and made a voluntary prepayment of $50 million on its USD term loan B. In May 2024, the Company completed a private offering of $1.4 billion aggregate principal amount of 1.25% convertible senior notes due 2030. In connection with the offering, the Company entered into capped call transactions, which are expected to reduce the potential dilution to the Company's common stockholders upon conversion of any notes, subject to a cap. The Company used substantially all of the net proceeds of the offering to pay the cost of the capped call transactions and repay approximately $1.2 billion in borrowings outstanding under its USD term loan B.

In July 2024, the Company completed the repricing of its USD term loan B and its EUR term loan B and made a voluntary prepayment of $110 million, consisting of $69 million to its USD term loan B and €38 million to its EUR term loan B.

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: Acquisition and integration costs related to the Atotech Acquisition.

Note 2: Restructuring and other costs primarily related to severance costs due to global cost-saving initiatives.

Note 3: 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.

Note 4: We recorded additional interest expense related to the amortization of debt issuance costs associated with our term loan facility.

Note 5: In the first quarter of 2024, we recorded fees and expenses related to an amendment to our term loan facility where we borrowed additional amounts under our USD term loan B and EUR term loan B and fully paid our term loan A.

Note 6: 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 7: During the three and six months ended June 30, 2024, we recorded a charge to write-off deferred financing fees and original issue discount costs related to extinguishment of debt on our USD term loan B and EUR term loan B. Additionally, during the three months ended March 31, 2024 and the six months ended June 30, 2024, we recorded a charge to write-off deferred financing fees related to the extinguishment of our term loan A.

Note 8: During the six months ended June 30, 2023, we recorded a reduction in benefit for income taxes for a retrospective approval of an income tax rate reduction from a foreign jurisdiction.

Note 9: Non-GAAP adjustments are tax effected at applicable statutory rates resulting in a difference between the GAAP and Non-GAAP tax rates.

Note 10: In the fourth quarter of 2023, we modified our definition of Adjusted EBITDA to exclude other (income) expense, net from this Non-GAAP measure. Other (income) 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.
