3-Step Filing-to-Valuation Summary

Cash-Flow Fact: 3Q26 CapEx/OCF: SK Hynix 21.8% (+47.3T FCF), TSMC 37.9% (+$16.6B net cash) vs US 4-Peer 115.1%
Valuation Estimate: Balance-sheet fortresses Hynix (4.17x Fwd P/E) & TSMC (26.97x P/E) are undervalued
6–12M Direction: ▲ BULLISH — Self-funded compounders outperform debt-issuing capex spenders in a 3.88% rate regime

Issuer & Live Multiples	Valuation & 6–12M Direction	Primary-Filing Basis & Catalyst
SK Hynix (000660.KS) 21.8% CapEx/OCF · 98.7T Net Cash · Fwd P/E 4.17x	UNDERVALUED (▲ Bullish)	Spends just 21.8% of OCF on CapEx while adding +29.3T KRW net cash in a single quarter
TSMC (2330.TW / TSM) 37.9% CapEx/OCF · NT$2.24T Net Cash · P/E 26.97x	UNDERVALUED (▲ Bullish)	Generates $15.97B quarterly FCF even after deploying $9.73B in leading-edge CapEx
Tesla (TSLA) 75.6% CapEx/OCF · $33.6B Net Cash · P/E 370.14x	OVERVALUED (▼ Cautious)	Strong $47.5B liquidity buffer, but 4Q CapEx step-up and 370.1x P/E limit near-term upside

Capital-cycle solvency check: across Tesla, TSMC, and SK Hynix, 3Q26 AI CapEx was funded out of operating cash flow and balance-sheet cash buffers rather than debt [1][2][3].

As of 2026.10.29 · Source: Tesla 3Q26 Form 8-K & 10-Q, SK Hynix & TSMC 3Q26 Releases · Derived ratios marked (Calc.).

1. Tesla: FCF Flipped Back to +$1.531B Backed by a Two-Layer Liquidity Buffer

Single-Quarter FCF Rebound: After dipping to -$1.092B FCF in 2Q26 on $5.789B CapEx, 3Q26 OCF rose +33.3% QoQ to $6.263B, covering $4.732B of 3Q CapEx ($13.01B in 9M26 toward a >$20B FY26 guide) and generating +$1.531B FCF [1].
$45.45B Cash + $30B Undrawn Line: Ending cash & short-term investments rose to $45.45B (vs. $43.52B in 2Q26, $41.65B in 3Q25), supplemented in Sept 2026 by $30B in undrawn credit facilities [1].

Check Item	3Q26 Disclosed Figures
Tesla Cash Flow	OCF $6.263B, CapEx $4.732B (1Q–3Q cumulative $13.01B), FCF +$1.531B (swung positive from -$1.092B in 2Q26)
Tesla Liquidity Buffer	Cash & short-term investments $45.45B (+$1.92B QoQ, Calc.), plus $30B credit facility limit signed in Sept 2026
TSMC Cash Flow	OCF NT$919.77B, CapEx NT$443.21B (US$13.84B), FCF NT$476.56B, full-year CapEx budget US$60B–$64B
SK Hynix Net Cash	Ending cash 114.5T KRW (+26.5T KRW QoQ), borrowings 15.8T KRW (-2.8T KRW QoQ), net cash 98.7T KRW
SK Hynix Returns & Reinvestment	FY26 return target ~100T KRW (incl. 40T completed buyback), 3Q board resolved 14T dividend + 20T buyback, Yongin fab starts in 2027
Upstream Order Visibility	TSMC raised 2026 USD revenue growth outlook to ~44%; SK Hynix secured LTAs for >50% of 2027–2028 capacity

2. TSMC & SK Hynix: Simultaneous Capacity Expansion + Shareholder Cash Return

TSMC (NT$476.56B 3Q FCF): 3Q26 OCF (NT$919.77B) - CapEx (NT$443.21B / US$13.84B; 9M26 US$40.64B) = NT$476.56B FCF [3]. Even while lifting 2026 USD revenue growth guidance to ~44%, TSMC held its annual CapEx budget steady at US$60B–$64B [3].
SK Hynix (98.7T KRW Net Cash & ~100T KRW Return Target): Cash rose +26.5T KRW QoQ to 114.5T KRW while debt fell -2.8T KRW QoQ to 15.8T KRW (18.6T → 15.8T) → Net Cash = 98.7T KRW [2]. That funds both the ~100T KRW FY26 shareholder return (40T completed Aug buyback + 14T 3Q dividend + 20T new buyback split 10T cancellation / 10T employee comp) and the 2027 Yongin Phase 1 ramp (with >50% of 2027–2028 output under LTAs and Solidigm's IPO halted) without external equity [2].

Takeaway & Next-Quarter Checks

3-Point Cycle Monitor: (1) Does Tesla keep funding CapEx out of OCF without drawing its $30B credit line? (2) Do ASPs absorb 2027 depreciation when TSMC doubles 2nm capacity and SK Hynix opens Yongin Phase 1 / maximizes M15X? (3) How do LTA price bands and CoWoS tightness feed into 4Q/1Q GPM guidance?
