MKS (MKSI): It Beat Every Line - And The Stock Shrugged. Here’s Why.

MKS Inc. (MKSI) Q2 2026 — MKS reports AFTER the close - the 8-K was accepted at 4:31pm ET on Aug 5 - so the -2.39% close at $313.10 is a PRE-print price, not the reaction. The reaction so far is the after-hours tape: last trade $309.25, -1.23%. Revenue $1,248M (+28.3%) beat a ~$1,195M bar, non-GAAP EPS $3.30 beat $2.91, and Q3 is guided to $1,350M and $3.58. MKS beat on revenue, on GAAP earnings, on non-GAAP earnings and on adjusted EBITDA - every one above the high end of its own guidance - then guided Q3 about 8% above the bar. And the stock moved roughly one percent. Here is the line almost nobody read: the diluted share count went from 67.4M to 72.7M, up 7.9%, because the share price itself satisfied the conversion condition on $1.4B of convertible notes. $1,399M of debt moved from long-term into current liabilities. The rally that produced this quarter is quietly issuing the equity. THE CALL: HOLD (3/5, AN EXCELLENT BUSINESS PRICED FOR A CYCLE THAT NEVER TURNS) — base-case value ~$265.0 vs ~$309.25 today. KEY METRICS: - CALL: HOLD 3/5, fair value ~$265 against the $309.25 after-hours print - about 14% BELOW the tape. We DIFFER sharply from the Street's $405.25 average (+31%). DCF base $263 at a 9.5% discount rate; bear $133; bull $415. Cross-check: 13-15x mid-cycle EBITDA gives $239-$284. - THE PRINT: Revenue $1,248M, +28.3% YoY from $973M, against a ~$1,195M bar. Non-GAAP EPS $3.30 vs a $2.91 bar (+13.4%) and $1.77 a year ago. GAAP EPS $2.41 vs $0.92. Gross margin 47.6% vs 46.6%. Adjusted EBITDA $358M, a 28.6% margin vs 24.7%. All above the HIGH END of guidance. - THE CONVERTIBLE - the line nobody read: the trading price satisfied the stock-price conversion condition on $1.4B of convertible senior notes. Diluted shares went 67.4M to 72.7M, +7.9%. Short-term debt went $51M to $1,399M against $611M of cash. Basic EPS was $2.59 and diluted was $2.41 - 18 cents already gone. - THE MIX: Electronics & Packaging $381M, +43.2%, is outrunning Semiconductor at $554M, +28.2%. Specialty Industrial $313M, +13.8%. Every division grew double digits and the incremental non-GAAP operating margin was 42.9% - which runs backwards just as fast in a down-cycle. - THE EV BRIDGE: $21.2B of market value plus $3,332M of net debt is roughly $24.5B of enterprise value - about 16% more than the headline market cap - or 17.0x 2026E adjusted EBITDA of ~$1.44B. Q3 guidance of $1,350M and $3.58 sits about 8% above the pre-print bar. What to watch: UP: Electronics & Packaging holding above 40% growth into 2027, the order book converting as management describes, or the convertible settling in a way that caps the share count. BEAR: a Q4 guide below $1,350M, gross margin slipping under the guided 47%, or working capital continuing to eat free cash flow while the diluted share count climbs again.
