Recent Company History

Recent earnings history for MKS shows consistent revenue growth and improving profitability. Q4 2024 revenue was $935M, rising through Q1–Q3 2025 to $988M, with Adjusted EBITDA in the $237M–$240M range and Non‑GAAP EPS above guidance midpoints. Management repeatedly highlighted deleveraging via multiple $100M voluntary term‑loan prepayments and strong semiconductor and electronics demand. Q4 2025 revenue reached $1,033M. Today’s Q1 2026 report continues this theme with revenue at the high end of guidance and key metrics above guided ranges.

Average Historical Move earnings

In the past year, MKSI reported 5 earnings releases with an average move of 2.76%, mixing strong rallies and occasional sell‑the‑news reactions. This Q1 2026 update fits into a pattern of solid fundamentals but variable price responses.

Earnings releases from Q4 2024 through Q4 2025 show revenue climbing from $935M to $1,033M, steady Adjusted EBITDA near $237M–$249M, and ongoing balance‑sheet work including term‑loan repricing, multiple $100M voluntary prepayments, and issuance of €1.0B senior notes, setting the stage for the current Q1 2026 results and updated guidance.

Analysis

The stock is up +5.5% following this news. A strong positive reaction aligns with the report’s high‑end Q1 2026 revenue of $1,078M and Non‑GAAP EPS of $2.30, each above guidance. Historically, earnings have produced mixed moves, with some double‑digit rallies and some selloffs despite solid results. Elevated leverage, sizeable convertible notes, and recent insider net selling could introduce future volatility as investors reassess balance‑sheet risk against improving demand and guidance.

Key Terms

adjusted EBITDA, non-gaap, senior notes, convertible senior notes, +2 more
6 terms
adjusted EBITDA financial
"Adjusted EBITDA of $277 million and Non-GAAP net earnings per diluted share..."
Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.
non-gaap financial
"Adjusted EBITDA of $277 million and Non-GAAP net earnings per diluted share..."
Non-GAAP refers to financial measures that companies use to show their earnings or performance without including certain expenses or income that are often added back to give a different picture. It matters because it can make a company's results look better or more favorable, but it may also hide important costs, so investors need to look at both GAAP (official rules) and non-GAAP numbers to get a full understanding.
senior notes financial
"private offering of €1.0 billion aggregate principal amount of 4.25% senior notes due 2034."
Senior notes are a type of loan that a company borrows from investors, promising to pay it back with interest. They are called "senior" because in case the company faces financial trouble, these lenders are paid back before others. This makes senior notes safer for investors compared to other types of loans or bonds.
convertible senior notes financial
"the appreciation of our stock price... under the indenture governing our convertible senior notes."
Convertible senior notes are a type of loan that a company issues to investors, which can be turned into company shares later on. They are called "senior" because they are paid back before other debts if the company runs into trouble. This allows investors to earn interest like a loan but also have the chance to own part of the company if its value rises.
revolving credit facility financial
"The Company also upsized its revolving credit facility from $675 million to $1.0 billion."
A revolving credit facility is a type of loan that a business can borrow from whenever it needs money, up to a set limit. It’s like having a credit card for companies—allowing them to borrow, pay back, and borrow again as needed, providing flexibility for managing cash flow or funding short-term expenses.
gaap financial
"GAAP net income of $84 million and net income per diluted share of $1.18"
GAAP, or Generally Accepted Accounting Principles, are a set of standardized rules and guidelines that companies follow when preparing their financial statements. They ensure consistency, transparency, and comparability across different companies, making it easier for investors to understand and compare financial information accurately. This helps investors make informed decisions based on trustworthy and uniform financial reports.

Additional Financial Information

During the first quarter of 2026, the Company completed a private offering of €1.0 billion aggregate principal amount of 4.25% senior notes due 2034. The Company used the net proceeds from the offering, together with the net proceeds from the partial refinancing of its then-existing USD term loan B and refinancing of its then-existing EUR term loan B, both of which were also completed during the first quarter of 2026, and cash on hand to prepay approximately $1.3 billion of, and refinance in full, its existing USD term loan B and refinance in full its existing EUR term loan B. The Company also upsized its revolving credit facility from $675 million to $1.0 billion. In addition, the Company increased its dividend from $0.22 per share to $0.25 per share and paid a cash dividend of $17 million.

At March 31, 2026, the Company had $569 million in cash and cash equivalents, $1.6 billion of secured term loan principal outstanding, $1.4 billion of convertible senior notes outstanding, €1.0 billion of senior notes outstanding and up to $1.0 billion of additional borrowing capacity under a revolving credit facility, subject to certain leverage ratio requirements. The appreciation of our stock price during the first quarter of 2026 resulted in the satisfaction of the stock price conversion condition under the indenture governing our convertible senior notes. As a result, the convertible senior notes are convertible, in whole or in part, at the option of the noteholders at any time during the second quarter of 2026, and were classified as short-term debt, net of issuances costs, at March 31, 2026.

In May 2026, the Company made a voluntary principal prepayment of $100 million on its USD term loan B.

Second Quarter 2026 Guidance

  • Revenue of $1,200 million, plus or minus $40 million
  • Gross margin of 47.0%, plus or minus 1.0%

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.

Restructuring and other includes incremental expenses incurred in connection with restructuring programs and other strategic initiatives, primarily related to changes in business and/or cost structure. Such costs may include third-party services, one-time termination benefits, facility-related costs, contract termination fees and other items that have no direct correlation to our future business operations.

Legal settlement includes charges related to the resolution of legal matters.

Amortization of intangible assets includes non-cash amortization expense associated with intangible assets acquired in acquisitions.

Loss on extinguishment of debt includes the non-cash write-off of unamortized debt issuance costs and original issue discount costs incurred from voluntary prepayments, refinancings and/or repricings of our term loan facility.

Amortization of debt issuance costs includes non-cash additional interest expense related to the amortization of debt issuance costs associated with our debt.

Loss from de-designation of interest rate hedges includes a cash loss from the de-designation of certain interest rate hedges in connection with the voluntary prepayment of the USD term loan B.

Fees and expenses related to debt activities includes direct third-party costs related to repricings or refinancings of our term loan facility and the issuance of our €1.0 billion of senior notes due 2034 in February 2026.

Convertible debt capped calls includes the antidilutive impact of the capped call transactions entered into in connection with the issuance of $1.4 billion of convertible senior notes in May 2024. The capped calls are designed to reduce potential dilution to the Company’s common stock and/or offset cash payments in excess of the principal upon conversion of the notes, subject to an initial cap of $237.42 per share (a 100% premium to the May 13, 2024 closing price of $118.71), subject to customary adjustments. Because the capped calls are excluded from GAAP diluted share calculations, GAAP and Non-GAAP diluted share counts will differ.

Tax effect of Non-GAAP adjustments includes the impact of Non-GAAP adjustments that are tax effected at applicable statutory rates resulting in a difference between the GAAP and Non-GAAP tax rates.
