SMIC Clears Final CSRC Regulatory Hurdle for $6B Acquisition of Semiconductor Manufacturing North China — Largest STAR Market Tech Deal

China's securities regulator (CSRC) granted final approval for SMIC's plan to issue 547.2 million A-shares to acquire the remaining 49% stake in Semiconductor Manufacturing North China (SMNC), its Beijing-based foundry subsidiary, in a deal valued at 40.6 billion yuan (~$5.97 billion USD). The approval was announced in regulatory filings covering May 22–23, with widespread coverage confirmed by May 23. Upon completion, SMNC becomes a wholly-owned SMIC subsidiary, consolidating China's domestic chip production capacity under a single fully state-aligned umbrella for the first time — the transaction is expected to be the largest deal in the history of Shanghai's STAR Market for technology stocks. SMNC operates 28nm–40nm mature-node capacity in Beijing primarily serving automotive, IoT, and industrial customers; full integration expands SMIC's unified production management over approximately 900,000 wafers per month across fabs in Shanghai, Beijing, Shenzhen, and Tianjin. The timing is strategically significant: AI-driven global fab demand is tightening capacity at foreign foundries, and SMIC separately noted that overseas clients are increasingly shifting legacy-node orders to Chinese fabs. SMIC's Q2 2026 guidance of $2.86–2.91 billion (+14–16% QoQ) was issued the same week, driven predominantly by AI chip orders. The SMNC consolidation directly supports MIIT's May 2026 internal directive requiring 70% domestic silicon wafer use and 50% domestic equipment for new fab capacity by end-2026 — SMIC now controls a single integrated production entity to execute that mandate across its entire wafer output.
