On September 14, Broadcom fell 3.69% in regular trading, trading at approximately $348.75/share, with turnover of $11.49 billion, as the stock faced a dual headwind from EU regulatory scrutiny and a broad semiconductor downturn.

On the news front, EU antitrust regulators are conducting a deep probe into Broadcom's licensing overhaul for VMware software following its $61 billion acquisition. Regulators have sent questionnaires to European cloud service providers, focusing on whether VMware products are non-substitutable and whether new certification mechanisms impose unfair restrictions. With a March 31 deadline approaching, some smaller European providers may lose the ability to sell VMware subscriptions, raising concerns over potential revenue risks to Broadcom's infrastructure software segment.

The pressure was amplified by a sweeping selloff across the semiconductor sector. Marvell Technology and ARM fell over 7%, Intel and ASML dropped more than 6%, while the Nasdaq Composite opened down 1.20%. Within the sector, NVIDIA declined 3.4%, Micron Technology fell 6.12%, AMD lost 5.24%, Intel dropped 5.77%, and Marvell Technology slid 6.68%.
