(NYSE:TSM ) generated $122.54 billion (69.9% market share). Samsung Foundry hit roughly $13 billion to $14 billion annualized run-rate (7.1% share). Intel Foundry’s $17.8 billion looks competitive on paper — but $17.5 billion of it was internal. External revenue? Just 1.7% of Taiwan Semi’s total. Profitability : Intel’s rivals both turned profits on advanced nodes while its foundry lost $2.5 billion in Q4 2025 alone and $10.3 billion for the year. Process leadership : Taiwan Semiconductor leads at 2nm and below. Intel’s 18A node (in ramp now) and 14A (2026–2027) target parity, with U.S.-based capacity as a key differentiator for government and hyperscaler customers wary of Taiwan risk. The Terafab partnership gives Intel a domestic, high-profile showcase that neither Taiwan Semi nor Samsung can match for U.S.-centric AI projects . It also positions Intel to capture advanced packaging revenue — EMIB and Foveros — where margins can hit 40%. Key Takeaway This Terafab win is real progress for Intel’s foundry ambitions. It validates the 18A technology roadmap, adds a high-volume external customer, and could accelerate the shift from $307 million in 2025 external revenue toward the billion-dollar deals needed for sustainable returns. That said, the unit still bleeds cash, forward P/E sits above 100, and the dividend remains suspended. No matter how you slice it, Intel’s turnaround hinges on executing these ramps without further delays. Smart investors should treat this as a catalyst, not a finished story. Intel reports earnings on April 23, so look out for updated backlog figures and 18A yield data. If external revenue starts climbing toward 10% to 15% of foundry totals by year-end, the foundry business could finally flip from drag to driver. In any case, this deal gives long-term Intel investors a clearer path to upside — provided it delivers the wafers on time. About the Author
