Sio Capital Management, LLC – SEC 13F Filing Analysis

Report Period: Q3 2025 (Ended September 30, 2025)

1. Portfolio Overview

Sio Capital Management manages a concentrated portfolio valued at approximately $244.37 million, spread across 35 individual holdings. The firm executed a significant strategic pivot during the quarter, reducing the total portfolio value by 6.7% (down from $261.84 million in the previous quarter).

2. Key Holdings

The portfolio is dominated by a mix of large-cap healthcare giants and high-growth mid-cap biotechnology firms.

  • Top Position: The largest holding is Celuity Inc (CELC), representing 15.90% of the portfolio ($38.85M). This is a new position established in Q3, signaling an aggressive entry into what the firm likely views as an undervalued or high-upside opportunity in oncology diagnostics.
  • Major Caps: The firm maintains substantial exposure to "Big Pharma," with Sanofi (SNY) at 10.87% and Merck (MRK) at 6.09%. Notably, Sanofi was the subject of the largest position increase during the quarter, growing by over 200%.
  • Biotech Concentration: Alkermes PLC and Biomarin Pharmaceutical (BMRN) round out the top five, reinforcing the firm's heavy tilt toward healthcare and life sciences.
  • Significant Weightings: Positions such as Centene Corp (CNC) and Kenvue (KVUE) provide exposure to managed care and consumer health, respectively, though these are outliers in a portfolio heavily skewed toward biotech.
