Brussels, Belgium – The European Union announced today that it believes Microsoft has violated antitrust regulations within the region by improperly bundling its Teams and Office products. The European Commission stated that Microsoft has been tying its communication and collaboration tool, Teams, to its productivity suites for businesses, Office 365 and Microsoft 365.

This news has caused Microsoft’s shares to dip slightly in premarket trading. The Commission has communicated its preliminary view to Microsoft, indicating that the tech giant’s actions are in violation of EU antitrust rules. The EU’s executive arm has labeled Microsoft’s bundling practices as “abusive.”

Meanwhile, European markets opened on a negative note on Tuesday following a downturn in U.S. market sentiment. The Stoxx 600 index started the day down 0.32%, with various sectors experiencing divergent trends. Tech stocks were hit hard, dropping 1.53%, while oil and gas sectors saw a rise of 0.99%.

On the other hand, Nvidia shares saw a boost in premarket trading after enduring its worst daily decline since April. The chipmaker’s stock was up over 3%, along with positive movements from AMD and Super Micro Computer.

In another market development, Pool Corp witnessed an 11% drop in its shares after revising its full-year earnings guidance. The company now expects its earnings per share for the year to fall within a lower range than previously forecasted. Sales for the company are trending downwards, showing a decline of 6.5% compared to the same period last year.

To wrap up, stock futures opened with minimal changes on Monday evening, with futures for the Dow Jones Industrial Average adding 25 points and S&P 500 futures hovering near the flatline. Nasdaq-100 futures also inched up by 0.07%, indicating a relatively stable start to the trading week.
