Microsoft (MSFT) Stock: Should You Buy After 22% Plunge?

TLDR

• Microsoft stock plunged 22% from all-time highs after January 28 earnings report revealed AI growth challenges
• Copilot adoption reached only 15 million licenses out of 400 million available Microsoft 365 seats
• Azure cloud revenue growth slowed to 39% from 40% previous quarter despite beating analyst expectations
• OpenAI represents $281 billion or 45% of Microsoft’s $625 billion order backlog creating concentration risk
• Stock trades at P/E ratio of 26.5, cheapest valuation in three years compared to Nasdaq-100’s 32.8 multiple

Microsoft stock has tumbled 22% from record highs following its fiscal Q2 2026 earnings release. Shares fell over 10% on January 28 alone as investors questioned the company’s AI momentum.

Microsoft Corporation, MSFT

The stock closed at $393.58 on February 5, marking a sharp retreat from its $555 peak. Despite posting 16.7% revenue growth over the trailing twelve months, concerns about AI execution have spooked Wall Street.

Microsoft’s Copilot virtual assistant has struggled to penetrate enterprise markets. The company sold just 15 million Copilot licenses for Microsoft 365 out of 400 million total business licenses available.

That 3.7% adoption rate doubled from a year earlier but disappointed investors. Copilot integrates AI capabilities into Word, Excel, Outlook and other productivity applications.

The company found more success with developers. Paid Copilot subscriptions for software developers surged 77% from the prior quarter.

Healthcare showed promise too. Dragon Copilot now assists over 100,000 medical professionals and processed 21 million patient encounters in Q2, tripling year-over-year.

Azure Growth Rate Decelerates

Azure cloud platform revenue increased 39% year-over-year in the second quarter. The result beat Wall Street’s 37.1% forecast but slowed from 40% growth three months earlier.

Investors interpreted the deceleration as a warning sign. Azure provides critical infrastructure and AI development tools for businesses building applications.

Microsoft pointed to data center capacity shortages as a limiting factor. The company’s order backlog from customers waiting for infrastructure ballooned 110% year-over-year to $625 billion.

OpenAI Concentration Creates Vulnerability

A closer look at the backlog revealed troubling details. OpenAI alone accounts for $281 billion or 45% of total future commitments.

The AI startup lacks sufficient cash reserves to fund those orders immediately. OpenAI must depend on investor capital and revenue expansion to meet obligations.

Microsoft’s CFO disclosed this concentration during the earnings call. Shareholder lawsuits emerged in February 2026 alleging the company misled investors about OpenAI dependence.

Capital spending reached $37.5 billion in Q2 2026 as Microsoft invests heavily in AI infrastructure. Company-wide gross margins contracted despite revenue gains, pressuring profitability.

The More Personal Computing division declined 3% year-over-year. Gaming revenue fell 9% with Xbox content and services dropping 5%.

Microsoft currently trades at a price-to-earnings ratio of 26.5 based on trailing earnings of $15.98 per share. That represents the lowest valuation in three years.

The Nasdaq-100 trades at a 32.8 P/E multiple, making Microsoft cheaper than most tech peers. Analysts project fiscal 2027 earnings of $19.06 per share, implying a forward P/E of 22.4.

The company maintains robust cash generation with a 25.3% free cash flow margin and 46.7% operating margin. Microsoft’s market capitalization stands at $2.9 trillion as of February 5, 2026.
