In-Depth Analysis of the Impact of European Regulatory Investigations into Microsoft 365 Price Hikes

The Swiss Competition Commission announced on January 15, 2026 that it had launched a preliminary investigation into the price hikes of Microsoft’s Microsoft 365 office software suite [1]. The investigation stems from complaints from multiple enterprises and government agencies regarding Microsoft’s substantial subscription fee increases in recent years. The Swiss regulator clearly stated, “recent fee increases may constitute signs of illegal restriction of competition”, and emphasized that Microsoft 365 “is widely used by private enterprises as well as numerous government agencies, public companies, and government-related entities” [1].

This is not the first time Microsoft has faced regulatory pressure in Europe. As early as September 2025, Microsoft reached a settlement agreement with the European Commission regarding antitrust issues related to Microsoft 365 and Teams [2]. Under the settlement, Microsoft committed to expanding interoperability, enhancing data portability, and adjusting the licensing, pricing, and discount practices for Microsoft 365, Office 365, and Microsoft Teams. Specifically, Microsoft agreed to increase the price difference (a 50% rise) between suites with Teams and those without, in response to competitors’ allegations of unfair competition through bundling [2].

The Microsoft 365 suite holds an absolute dominant position in the office software market, with a market share of 87.5% as of 2025 [3]. This near-monopoly market position gives its pricing strategy significant industry influence. Starting in January 2025, Microsoft implemented global price adjustments for Microsoft 365, with notable price increases for personal and home editions, and synchronized hikes for enterprise editions [4].

Microsoft’s business model is undergoing a fundamental transformation from traditional perpetual licenses to cloud subscription services. Data for FY2025 Q1 (as of September 30, 2025) shows that Microsoft 365 Commercial products and cloud services revenue reached $23.97 billion, accounting for 30.9% of total revenue, with a 15% year-on-year increase (at constant currency) [5]. On the consumer side, Microsoft 365 subscription users grew to 89 million, with cloud revenue increasing by 11% [5].

Microsoft’s cloud subscription business has become the company’s core growth engine. According to the latest financial report data:

Business Segment	FY2026 Q1 Revenue	Year-on-Year Growth Rate	Revenue Share
Microsoft 365 Commercial	$23.97B	+15%	30.9%
Server Products & Cloud	$28.87B	+22%	37.2%
Azure	Est. $21B+	+40%	-
Gaming	$5.51B	+44%	7.1%
LinkedIn	$4.71B	+10%	6.1%

The revenue growth of Microsoft 365 Commercial is driven by two key factors:

(primarily fueled by small and medium-sized enterprises and frontline employee businesses) and (stemming from price increases) [5]. The consumer business also shows simultaneous growth in user count and ARPU: subscription users increased by 8% to 89 million, and revenue per user rose by 11% due to price hikes [5].

The competitive advantage of Microsoft 365’s subscription model is built on the following key pillars:

: Microsoft 365 forms a complete office ecosystem including Outlook, Teams, SharePoint, and OneDrive. Once users establish work processes and accumulate documents, the switching costs are extremely high [3]. This “lock-in effect” provides Microsoft with strong pricing power.

: The launch of the Microsoft 365 Copilot AI assistant represents a significant monetization opportunity. The enterprise version of Copilot is priced at $30 per user per month, and as enterprise adoption accelerates, it is expected to generate billions of dollars in incremental revenue [3].

: The subscription model brings stable and predictable cash flow, reducing revenue cyclicality. For full-year FY2025, revenue from the Productivity and Business Processes segment increased by 13% year-on-year (+$14 billion), mainly driven by growth in Microsoft 365 and LinkedIn [5].

Microsoft’s subscription business exhibits high-quality financial characteristics:

• High Profit Margins
  : Overall operating margin of 46.27%, net margin of 35.71%, indicating strong profitability of the subscription business [0]
• Adequate Free Cash Flow
  : Latest annual free cash flow reached $71.6 billion, with a healthy FCF margin [0]
• Excellent Capital Efficiency
  : ROE of 31.53%, reflecting strong shareholder return capability [0]

Based on analysis of the regulatory investigation progress, we identify the following potential business impact pathways:

: The EU settlement already requires Microsoft to increase the price difference between Teams-included and Teams-excluded suites by 50%, which essentially reduces the perceived value of bundled products and may cause some price-sensitive customers to opt for separate purchase plans [2]. If the Swiss investigation escalates to a formal inquiry, it may further restrict Microsoft’s pricing freedom.

: Regulators may require Microsoft to provide more flexible product portfolio options, allowing customers to purchase specific components individually instead of being forced to subscribe to the full suite. This will change the current “all-or-nothing” sales model, potentially reducing average revenue per customer.

: To meet regulatory requirements, Microsoft needs to invest resources in product restructuring, pricing system updates, and sales staff training. Estimated compliance costs range from $0.5 to $1.5 billion [0].

: Regulatory intervention may weaken the competitive barriers Microsoft has built through bundling strategies. Competitors (such as Google Workspace, Oracle, Salesforce, etc.) may gain more market access opportunities, which could erode Microsoft’s market share advantage in the long term.

: If regulation restricts Microsoft’s ability to create value through product integration, it may reduce the expected return on R&D investment. However, given Microsoft’s leading position in AI (such as Copilot), the possibility of a substantial decline in innovation incentives is low.

: Regulatory scrutiny may require Microsoft to adopt more consistent pricing strategies across different regions, limiting its ability to engage in price discrimination targeting specific markets.

Regulatory pressure may bring the following competitive dynamics to the market:

• Google Workspace Benefits
  : As the main alternative to Microsoft 365, Google’s collaboration tool suite may attract price-sensitive enterprise customers
• Opportunities for Open-Source Solutions
  : Open-source office software such as LibreOffice may receive more attention from enterprises, especially cost-sensitive small and medium-sized enterprises
• Integration of Niche Markets
  : Some customers may turn to specialized solutions for specific functions (such as project management tool Asana, document collaboration tool Notion, etc.)

Microsoft’s current market capitalization is $3.39 trillion, with a share price of $456.66, corresponding to the following valuation multiples [0]:

Valuation Metric	Value	Industry Comparison
P/E (TTM)	32.35x	Moderately High in the Technology Industry
P/B	9.35x	Reflects Premium for High-Quality Assets
EV/OCF	23.30x	Reasonable Level

The analyst consensus rating is “Buy”, with a target price of $645, implying 41.2% upside potential compared to the current price [0]. 80.8% of analysts have given a Buy recommendation, while only 19.2% maintain a Hold rating [0].

Based on the fact that European business accounts for approximately 28% of total revenue (corresponding to annualized revenue of approximately $26.85 billion), we have constructed a three-scenario valuation impact model:

: No substantive conclusions from the regulatory investigation, Microsoft maintains its existing pricing strategy

• Revenue Impact: $0
• Share Price Impact: $0

: Regulators require limited adjustments, prices decrease by 5%, compliance costs of $0.5 billion

• Net Income Impact: -$1.31 billion
• Share Price Impact: -$3.48 (-0.76%)

: Regulators impose strict restrictions, prices decrease by 12%, compliance costs of $1.5 billion

• Net Income Impact: -$3.38 billion
• Share Price Impact: -$9.01 (-1.97%)

: -$2.85 per share, adjusted target price to $453.81

Price Change	Impact on European Business Revenue	Share Price Impact
-15%	-$4.03B	-$10.74
-10%	-$2.68B	-$7.16
-5%	-$1.34B	-$3.58
0%	0	0
+5%	+$1.34B	+$3.58

The regulatory investigation brings the following risk factors to Microsoft’s share price:

: The market already has certain expectations for regulatory news, and the Swiss investigation is still in the preliminary stage, with no substantive impact yet evident.

: If the investigation escalates to a formal process and leads to product restructuring, it may drag down FY2026 revenue growth by 1-2 percentage points.

: Microsoft’s core competitiveness (ecosystem integration, AI innovation capabilities, brand recognition) is not easily shaken by regulatory intervention. Even if regulators require product unbundling, enterprise customers will still tend to stay in the Microsoft ecosystem due to high switching costs.

---

: The regulatory risks facing Microsoft 365 have limited impact on the overall business. The reasons are as follows:

1. The subscription business has extremely high customer stickiness, and regulators cannot force customers to switch platforms
2. Regulation mainly affects pricing strategies and bundling methods, rather than fundamentally prohibiting the business model
3. European business accounts for only about a quarter of Microsoft’s total revenue

:

• 40% growth in Azure cloud services provides strong momentum [0]
• Incremental monetization potential of the AI assistant Copilot
• Robust financial position (low debt risk rating) [0]
• Sustained strong free cash flow generation capability

Maintain a

rating. Even in the severe impact scenario, the share price decline is controlled within 2%, while the analyst target price of $645 offers 41% upside potential. Regulatory risks are more of a restriction on upside potential rather than a substantial increase in downside risks.

Investors should focus on the following catalysts:

1. Progress of the Swiss Investigation
   : Whether it escalates to a formal investigation process during Q1-Q2 2026
2. Implementation of the EU Settlement
   : The actual impact of pricing adjustments implemented since November 2025 on European sales
3. FY2026 Q2 Earnings Report
   (released on January 28, 2026): Revenue growth rate and customer retention of European business
4. Copilot Adoption Rate
   : The penetration speed of the enterprise AI assistant will determine the long-term growth trajectory

• Escalation of the regulatory investigation may lead to more stringent remedial measures
• An economic recession may suppress enterprise IT spending and affect subscription renewal rates
• Intensified competition in the AI field may erode Copilot’s first-mover advantage
• Macroeconomic uncertainty (inflation, interest rate hikes) may compress valuation multiples for technology stocks

The preliminary investigation by the Swiss Competition Commission into Microsoft 365 price hikes is the latest regulatory challenge Microsoft faces in Europe, but it is unlikely to fundamentally shake its subscription business model or market valuation. Microsoft 365’s core competitiveness—enterprise ecosystem integration and high switching costs—provides a buffer against regulatory intervention. Scenario analysis shows that even in the most adverse scenario, the potential impact on share price is only about 2%, while the analyst target price still offers over 40% upside potential.

Microsoft’s cloud subscription business has established a strong competitive moat, coupled with incremental value brought by AI innovation (Copilot). We believe regulatory risks are manageable short-term disturbances. For long-term investors, the current valuation level (32x P/E) provides an attractive entry opportunity.
