Microsoft on Wednesday reported an 11% increase in profit for the July-September quarter compared to the same time last year as investors looked for signs that the company's huge spending on artificial intelligence is paying off. The company reported quarterly net income of $24.7 billion, or $3.30 per share, which beat Wall Street expectations. Analysts polled by FactSet Research were expecting Microsoft to earn $3.10 per share on revenue of $64.6 billion.
