ANDOVER, Mass., April 26, 2021 (GLOBE NEWSWIRE) -- MKS Instruments, Inc. (NASDAQ:MKSI), a global provider of technologies that enable advanced processes and improve productivity, today reported first quarter 2021 financial results.

"We delivered another quarter of record revenue and earnings, as we continue to see strong demand trends in our Semiconductor Market, as well as an acceleration in revenue from our Advanced Markets," said John T.C. Lee, President and Chief Executive Officer. "In our Semiconductor Market, demand was broad-based, as we delivered new quarterly revenue records for our Pressure, Valves, and Flow solutions, while also delivering another robust quarter in Power solutions. As evidenced by recently released VLSI research data for 2020, we gained significant share in the total Critical Subsystems category in 2020, and our portfolio breadth, operational track record and focused innovation strategy position us to continue to outperform our peers."

Mr. Lee added, "Revenue from our Advanced Markets accelerated further in the first quarter, growing 27% year-over-year. We are seeing growing demand for our Surround the Workpiece^® portfolio in Advanced Electronics Manufacturing applications, and we expect momentum to extend into the second quarter."

"We are pleased to deliver first quarter gross margins that exceeded the high end of our guidance, and combined with our continued cost control, enabled us to generate strong Non-GAAP operating margin expansion of 110 basis points sequentially, and 530 basis points year-over-year," said Seth H. Bagshaw, Senior Vice President and Chief Financial Officer.

Mr. Bagshaw added, "Our balance sheet continues to strengthen, as we exited the quarter with $78 million in net cash. Our strong financial position provides added flexibility in executing on our capital allocation priorities."

Second Quarter 2021 Outlook

Based on current business levels, the Company expects revenue in the second quarter of 2021 of $740 million, plus or minus $30 million. At these volumes, the Company expects GAAP net income per diluted share of $2.70, plus or minus $0.26, and Non-GAAP net earnings per diluted share of $2.92, plus or minus $0.26.

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.

Note 1: Acquisition and integration costs during the three months ended March 31, 2021 primarily related to our proposed acquisition of Coherent, Inc. Acquisition and integration costs during the three months ended March 31, 2020 and December 31, 2020 related to integration costs from our acquisition of Electro Scientific Industries, Inc., which closed on February 1, 2019.

Note 2: We recorded additional interest expense related to the amortization of debt issuance costs related to our Term Loan Credit Agreement and our ABL Credit Agreement (each credit agreement, as defined in our Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the SEC on February 23, 2021).

Note 3: Restructuring and other costs during the three months ended March 31, 2021 primarily related to severance costs due to a global cost saving initiative and duplicate facility costs attributed to entering into new leases. Restructuring and other costs during the three months ended December 31, 2020 and March 31, 2020 primarily related to duplicate facility costs attributed to entering into new leases, and costs related to the pending closure of a facility in Europe. Such costs for the three months ended March 31, 2020 were offset by an insurance reimbursement related to a legal settlement.

Note 4: During the three months ended March 31, 2020, we recorded an asset impairment charge as a result of the write-down of long-lived assets related to the pending closure of a facility. During the three months ended December 31, 2020, we recorded the write-off of goodwill related to the pending closure of a facility in Europe.

Note 5: We recorded windfall tax benefits on the vesting of stock-based compensation.

Note 6: We recorded additional withholding taxes on inter-company undistributed earnings following the United Kingdom's departure from the European Union.

Note 7: Non-GAAP adjustments are tax effected at applicable statutory rates resulting in a difference between the GAAP and Non-GAAP tax rates. For the three months ending June 30, 2021, we forecast a GAAP and Non-GAAP tax rate of approximately 17%.
