On August 3, Microsoft rose 3.83% in regular trading, trading at $488.535/share, with turnover of $5.304 billion. The stock extended its post-earnings rally as a new enterprise cloud partnership provided fresh catalyst.

ArcelorMittal announced an expansion of its collaboration with Microsoft, designating Azure as its primary cloud computing platform as part of its comprehensive digital transformation strategy. The steelmaker stated it will embed data and AI deeply into business operations to drive scalable digital innovation and data-driven decision-making across its global industrial footprint.

The partnership adds to strong post-earnings momentum following Microsoft's Q4 FY26 results released on July 29, which showed revenue of $90 billion (up 18% YoY) exceeding expectations, EPS of $4.74 versus the $4.25 consensus, and Azure cloud revenue growing 43% YoY with annual revenue surpassing $100 billion for the first time. At least nine brokerages raised their target prices following the report, with consensus now around $560. The stock surged over 15% on earnings day, setting a record for the largest single-day market cap gain in U.S. corporate history at approximately $450 billion.
