ASE Technology (ASX): Its Best Quarter Ever — And It Just Burned $1 Billion in Cash

ASE Technology Holding Co., Ltd. (ASX) Q2 2026 — Revenue was NT$191,064M (about US$6.05B), +26.7% YoY and +10.0% QoQ — an all-time record. Gross margin rose to 21.0% from 20.0% and operating income of NT$21,134M was +107% YoY; net income was NT$21,068M vs NT$7,521M. Basic EPS NT$4.80 = US$0.304 per ADS vs consensus near US$0.23. CONVENTION: ASE reports in New Taiwan dollars, 1 ADS = 2 common shares, NT$31.59 = US$1. ATM (assembly and test) did NT$126,148M, +36.3%, at a 27.3% gross margin and 15.7% operating margin — both UP; EMS did NT$65,789M, +11.9%, at 8.9% gross and 2.4% operating — both DOWN. ATM is 66% of revenue and 93.6% of operating income. Testing revenue grew 42.5%, faster than packaging's 34.9%, and computing rose to 30% of ATM revenue from 24%. But free cash flow was MINUS NT$32,835M (about −US$1.04B) on NT$79,849M of cash capex against NT$47,014M of operating cash flow, funded with NT$39,864M of new borrowings as net debt/equity went 0.40 to 0.47. Two things trip everyone up: this is ASE Technology Holding (NYSE: ASX, Taipei 3711), NOT the Australian stock exchange; and one ADS equals TWO common shares at NT$31.59/US$1, so NT$4.80 of EPS is 30.4 US cents per ADS, not 15. ASE is two companies in one ticker — ATM, the real semiconductor business, expanded gross margin to 27.3% while EMS fell to an 8.9% gross and 2.4% operating margin, so the blended 21.0% hides the good business. The AI leverage is measurable: computing went 24% to 30% of ATM revenue and testing grew 42.5%. The most under-covered number is the machine count — testers went 6,797 to 8,348 (+23%) while wirebonders SHRANK from 25,156 to 24,815, and US$804M of US$1,695M equipment capex went into testing. ASE is converting itself into a test house. But the headline capex understates the cash: actual PP&E payments were US$2.53B, 49% more, so free cash flow was about MINUS US$1.04B in the best quarter this company has ever had — funded with debt. We value it on owner earnings (operating cash flow less maintenance capex) of ~US$3.04B/yr, with capex split 31% maintenance / 69% growth. At an 11% discount rate: $16 if the cycle rolls over, $37 if AI packaging is secular, $24 mid case; a 12x FY26E EBITDA cross-check gives $28. We blend to ~$26 per ADS — still ~16% BELOW the $31.12 price even after a 32% drawdown from the June high of $45.52. THE CALL: HOLD (3/5, A RECORD QUARTER, STILL PRICED FOR PERFECTION) — base-case value ~$26.00 vs ~$31.12 today. What to watch: free cash flow turning positive while ATM revenue is still growing — the proof the capacity build pays for itself rather than being financed. We would also raise our number on ATM operating margin pushing through 18% (15.7% today), testing growth holding above 40%, or LEAP tracking above its US$3.5B 2026 guide. What breaks it is ATM gross margin flattening WHILE capex stays at this pace. Buyers again under about $24. Also on YouTube: @ChargedAlpha DISCLAIMER: For informational and educational purposes only.
