This former Palantir bear changed his tune on the stock. Here's why.

Mizuho Securities upgraded Palantir (PLTR) to Neutral from Underperform, citing the company's "stunning" execution and momentum across its commercial and government businesses, which could lead to continued revenue acceleration. Despite acknowledging Palantir's extremely high valuation (EV/Sales 97x/77x for 2025/2026) and the potential for multiple reversion, the analysts credit its unique positioning in AI and digital transformation. However, Mizuho remains hesitant to issue a Buy rating, suggesting other software names are more compelling at current levels, and their $135 price target is below recent trading.

Analysis

Mizuho Securities has upgraded Palantir Technologies (PLTR) to Neutral from Underperform, a notable shift from a previously bearish stance driven by the company's 'stunning' recent execution. The upgrade acknowledges a high probability of a fifth consecutive quarter of accelerating revenue growth, supported by exceptional momentum in its U.S. commercial business, which is guided for at least 68% growth this year, and its government segment, which is expected to sustain growth above 40% due to geopolitical tailwinds. Operational catalysts include effective AIP bootcamps that are compressing sales cycles and expanding use cases into new sectors like finance and healthcare. However, this operational strength is juxtaposed with extreme valuation concerns. Palantir trades at an enterprise-value-to-sales multiple of 97 times estimated 2025 sales, which the analyst notes is 'dramatically above anything else in software.' This valuation creates a significant risk of 'material multiple reversion.' The analyst's caution is underscored by a $135 price target, which is below the stock's recent trading level of approximately $150, and the explicit statement that more compelling investment opportunities exist in the software sector.

Key Decisions for Investors

• Investors holding Palantir should recognize this upgrade as validation of the company's operational momentum, but must remain aware that its extreme valuation makes the stock highly vulnerable to a sharp correction if growth decelerates.
• Potential new investors should exercise caution, as the upgrade only to Neutral combined with a price target below the current market price suggests the risk-reward profile is not compelling for fresh capital at these levels.
• Monitor Palantir's upcoming second-quarter earnings closely, as confirmation of continued revenue acceleration could sustain momentum, whereas any sign of a slowdown may act as a catalyst for the 'multiple reversion' the analyst fears.
• Consider evaluating other AI-related software companies that may offer similar thematic exposure but trade at more conventional valuations, as suggested by the analyst's view that more compelling names exist.
