Smart Analysis
Regeneron Pharmaceuticals Inc (REGN) · 10 metrics scored
Smart Score
Category Performance
WallStSmart pulls financial metrics like revenue growth, profit margins, and valuation ratios and scores each one from 0 to 10 based on how strong or weak it is. Those 10 scores are grouped into 4 categories: Growth, Profitability, Valuation, and Quality — which form the 4 axes of the spider chart you see. The categories are then combined into a final score out of 100, but not equally. Growth and Profitability together count for 60% of the total, because a fast-growing profitable business matters more than just a cheap one. That final number maps to a rating (Strong Buy, Buy, Hold, Avoid) and a letter grade, giving you one clear Stock Rating.

Regeneron Pharmaceuticals Inc (REGN) Detailed Analysis Report
Overall Assessment
This company scores 58/100 in our Smart Analysis, earning a C grade. Out of 10 metrics analyzed, 4 register as strengths (avg 9.3/10) while 6 fall into concern territory (avg 3.8/10). The category breakdown reveals uneven performance, with some areas requiring attention.
The Bull Case
The strongest argument centers on Profit Margin, Institutional Own., Market Cap. Profitability is solid with Operating Margin at 23.10%, Profit Margin at 31.40%.
The Bear Case
The primary concerns are EPS Growth, Revenue Growth, Price/Sales. Some valuation metrics including PEG Ratio (1.56), Price/Sales (5.47), Price/Book (2.48) suggest expensive pricing. Growth concerns include Revenue Growth at 2.50%, EPS Growth at -2.60%, which may limit upside. Profitability pressure is visible in Return on Equity at 14.90%.
Key Dynamics to Monitor
Three factors to monitor going forward. First, whether EPS Growth improves, as this is the primary drag on the overall score. Second, margin trajectory, with Return on Equity at 14.90% needing improvement to support the investment thesis. Third, growth sustainability, with Revenue Growth at 2.50% needing to reaccelerate.
Risk Considerations
Based on the metric profile, this is a moderate-to-high risk investment. There are more areas of concern than strength, warranting a more conservative position size. Investors should size positions according to their risk tolerance and maintain diversification.
Bottom Line
Mixed fundamentals with both positives (Profit Margin, Institutional Own.) and negatives (EPS Growth, Revenue Growth). A cautious approach is warranted. Monitor for improvement in weak areas before increasing conviction.
