Episode Details

Ultra Clean Holdings, Inc. (UCTT) Q2 2026 — Reported August 3, 2026 after the US close for Q2 2026 (the quarter ended June 26, 2026). Revenue $644.9M (+24.3% YoY, +20.8% QoQ) vs a $587.6M consensus and the company's own $565-605M guidance - a beat above the TOP END. Products $572.7M (+25.9%), Services $72.2M (+13.0%). GAAP gross margin 16.1%, operating margin 4.6%, net income attributable to UCT $8.7M or $0.19/sh. Non-GAAP gross margin 16.7%, operating margin 7.0%, net income $32.3M or $0.70/sh vs a $0.531 consensus. Q3 2026 guidance: revenue $700-750M (+12% QoQ at the midpoint, +42% YoY), GAAP EPS $0.67-0.87, non-GAAP EPS $0.83-1.03. Shares closed the regular session at $89.17 (+7.0%) BEFORE the release; the reaction session had not opened when this episode was recorded, and UCTT traded around $96.84 in the pre-market, about +8.6%. The stock is up more than 300% from its $21.63 low of August 6, 2025 and 37% below its $142.59 high of June 30, 2026. The line nobody printed: revenue grew 24% and free cash flow was MINUS $100.2M. First-half operating cash flow was -$74.4M against +$57.4M a year ago - a $131.8M swing - and capex took another $25.8M. The bridge is one line: inventories consumed $238.9M of cash, with the balance going from $390.9M in December to $629.9M in June, roughly 106 days on hand against ~83 at year end. Accounts payable gave back $104.4M, so part of the build is being funded by stretching suppliers. Two more things nobody flagged. FIRST, the refinancing is doing about 40% of the earnings growth: interest expense fell to $1.1M from $10.1M after March's $600M 0.00% convertible notes replaced $481.5M of bank debt - roughly $0.16/sh after tax out of a $0.37 YoY improvement in non-GAAP EPS - and those notes convert at $84.75, below the $89.17 close, carrying 7.1M shares or 15.4% dilution. SECOND, the Q3 guide implies a GAAP-to-non-GAAP gap of just $0.16 against $0.51 this quarter; intangible amortisation alone is $0.15/qtr, so the US tax valuation allowance drag has to essentially vanish - a one-time, non-cash benefit, not earnings power. THE CALL: AVOID (3/5, A GREAT QUARTER AT A PRICE WE CANNOT UNDERWRITE) — base-case value ~$62.0 vs ~$89.17 today. KEY METRICS: - CALL: AVOID 3/5 - fair value ~$62 vs the $89.17 close (about -30%), and below the LOWEST price target on Wall Street ($70). This is not a call on the business, which is executing; it is a call on the price of entry. DCF on free cash flow AFTER charging stock-based compensation as a real cost: revenue from ~$2.67B (2026E) to $3.81B by 2031, non-GAAP operating margin 7.0% -> 9.0%, SBC ~$36M growing 5%/yr, capex 2.6% of revenue vs D&A 1.9%, and working capital taking 20 cents of every incremental revenue dollar. At 10.5% and 2.5% terminal growth: PV of 2027-2031 FCF $476M + PV of terminal value $1,444M = EV $1,920M, less $343.5M net debt and $77.3M of noncontrolling interests, / 46.1M diluted shares = $32.52. Bear $12.20, bull $58.51; probability-weighted 25/50/25 = ~$34. We carry ~$62 because semi-cap is priced on mid-cycle earnings multiples, not on DCF: $3.25 of mid-cycle non-GAAP EPS at 18x is $58.50, and $5.00 of peak 2027 EPS at 16x is $80. - REVERSE DCF - THE WHOLE ARGUMENT: at $89.17 the market capitalisation is $4.11B on 46.1M diluted shares and enterprise value is $4.53B - 1.69x revenue and 24.5x our FY2026 non-GAAP operating income estimate of $185M. Growth does NOT close the gap: we tested a 20% five-year revenue CAGR and the model still prints $28, because every incremental dollar of revenue drags ~20 cents of working capital with it. What $89.17 requires is a terminal OPERATING margin near 17% - against a GROSS margin of 16.7%. The discounted cash flow cannot get there at all, at any discount rate: even at an implausibly generous 7.5%, the base case is under $60. - THE CASH: first-half operating cash flow -$74.4M (vs +$57.4M a year ago) less $25.8M capex = -$100.2M of free cash flow, against +$28.2M in the same half of 2025.
