As of May 18, 2025, the company’s stock price has become a focal point for investors and analysts alike, following its recent announcement regarding the anticipated 2027 BLA submission for Rese-cel in Myositis.

A Year of Volatility

The past year has been a rollercoaster for Cabaletta Bio’s stock. From a 52-week high of $13.5 USD on June 13, 2024, the stock plummeted to a low of $0.9857 USD on April 6, 2025.

This volatility has drawn the attention of market watchers, who are keen to understand the underlying factors driving these fluctuations.

Valuation Challenges

The company’s valuation metrics present a complex picture. With a price-to-earnings ratio of -0.718171 and a book ratio of 0.41638, Cabaletta Bio’s financials suggest a challenging valuation landscape.
