Infineon's stock plunges 7% after UBS downgrade on China demand fears
Infineon Technologies has faced a sharp drop in its stock value after a downgrade by UBS. The analyst firm now predicts weaker demand in China, a key market for the semiconductor company. This comes despite recent growth in Infineon's market share and strategic investments.
On March 12, UBS analyst François-Xavier Bouvignies cut Infineon's rating from 'Buy' to 'Neutral'. The price target was also reduced from €47 to €45. Following this announcement, the company's shares fell by over 7% in a single trading session.
China plays a major role in Infineon's revenue, accounting for about 30% of its total sales. The automotive sector, which makes up 43% of the company's business, has seen strong growth there. Over the past two years, demand for automotive semiconductors in China surged by 15-20% annually, driven by electric vehicle production. The country sold over 8 million EVs in 2024, far outpacing the US and Europe. However, UBS now expects a 7% decline in China's automotive sales for 2026 and 2027 due to weak demand and rising competition from local chipmakers.
Despite these challenges, Infineon has expanded its global presence. The company's microcontroller market share rose to 23.2% in 2025, up from 21.4% the previous year. It also opened a new €60 million R&D centre in Cork, Ireland, creating around 100 jobs. Additionally, Infineon partnered with Subaru on advanced driver assistance systems and acquired Marvell's automotive Ethernet business.
The next quarterly report, due on May 6, 2026, will show whether Infineon's operational progress can balance the slowdown in China. Currently, the stock trades at €41.61, below its 52-week high of €47.03 and under its 50-day moving average of €42.62.
Infineon's stock decline reflects concerns over China's automotive market, a critical revenue source. The upcoming quarterly results will reveal how well the company's growth in market share and new investments can counter these pressures. For now, the stock remains under its recent highs, with investors watching closely for further developments.
