MKS Inc. MKSI used its second-quarter 2026 call to frame AI-driven spending as the key force behind accelerating semiconductor and advanced-packaging demand. Management paired that view with plans to expand manufacturing capacity while preserving operating leverage.
Revenues of $1.25 billion exceeded the Zacks Consensus Estimate of $1.21 billion, while adjusted earnings of $3.3 per share topped the $2.94 consensus estimate. The larger message was that demand visibility now extends well beyond the current quarter.
MKSI Sees Semiconductor Growth Accelerating
President and chief executive officer John Lee said the third-quarter semiconductor outlook implies year-over-year growth of more than 50%, with strength across MKS' portfolio. He also cited a healthy backlog supporting second-half visibility.
Second-quarter semiconductor revenues reached $554 million, up 19% sequentially and 28% year over year. Growth spanned deposition and etch products, NAND-related RF power upgrades, vacuum, plasma, reactive gases, optics and photonics.
A KeyBanc Capital Markets analyst pressed management on NAND. Lee said upgrades should continue before greenfield fabs arrive toward late 2027 and early 2028, with new tools offering broader content opportunities beyond RF power.
MKS Packaging Demand Extends Into 2027
Lee described chemistry equipment demand as the strongest MKS has seen, supported by AI server investment, including optical modules. Electronics and Packaging revenue rose 19% sequentially and 44% year over year to $381 million.
MKS now has chemistry equipment visibility through 2027 and is doubling Guangzhou capacity. Lee said the company has also reactivated its Germany factory to bridge demand until new Guangzhou capacity comes online in the third quarter of 2027.
A Cantor Fitzgerald analyst asked about chemistry. Lee said AI-related applications now account for roughly 15% to 20% of chemistry revenue, while volume chemistry can take 24 to 30 months to ramp after equipment installation.
MKSI Builds Capacity Ahead of Demand
Lee said MKS' new Malaysia center has begun shipping revenue, though management did not need that capacity to satisfy 2026 demand. The facility is being ramped for 2027 and beyond.
Responding to a BMO Capital Markets analyst, Lee said a fully built-out Penang site could support wafer fab equipment spending in the $200 billion to $250 billion range. That plan complements the Guangzhou expansion.
Executive vice president and chief financial officer Ram Mayampurath said factory ramp expenses are costing about 50 to 80 basis points of gross margin per quarter and should persist for at least the next couple of quarters.
MKS Guides to Another Sequential Step-Up
Mayampurath guided third-quarter revenues to $1.35 billion, plus or minus $40 million. Semiconductor revenues are expected at $630 million, Electronics and Packaging at $385 million, and Specialty Industrial at $335 million.
Third-quarter adjusted earnings are projected at $3.58 per share, plus or minus $0.31. Adjusted EBITDA is expected at $395 million, plus or minus $28 million.
Management expects a 47% gross margin, plus or minus 100 basis points, with mix and capacity investments weighing on profitability. Mayampurath said operating expenses should grow much slower than revenues.
MKSI Keeps Deleveraging Behind Growth Investment
Free cash flow was $188 million in the second quarter, or about 15% of revenues. MKS ended the period with more than $1.6 billion of liquidity and leverage of 3 times trailing adjusted EBITDA.
Mayampurath said organic growth remains the first capital priority, with balance-sheet strengthening a close second. He expects capital expenditures and inventory to rise in the second half.
A Cantor Fitzgerald analyst asked about voluntary debt payments. Mayampurath said MKS continues $100 million quarterly term-loan prepayments and is evaluating additional payments in the third and fourth quarters.
MKS Focuses on Execution Through the Ramp
Lee emphasized that customers are sharing plans further out than normal, while MKS is adding labor, inventory and capacity to avoid becoming a constraint. He said lead times remain normal and the supply chain is keeping pace.
Management's posture centered on scaling for semiconductor and packaging growth without abandoning pricing discipline, customer relationships or deleveraging. MKS is accepting near-term margin pressure from capacity and equipment mix to support the ramp.
