  This prospectus registers 5,000,000 shares of common stock for resale by selling stockholders, finalizing the terms of the offering initiated with the S-3 filing on April 3, 2026.

• No Direct Proceeds to Company

  Kalaris Therapeutics will not receive any proceeds from the sale of these shares by the selling stockholders, except for the exercise price of pre-funded warrants.

• Shares Acquired at Significant Premium

  The shares were originally acquired by selling stockholders in a private placement on December 17, 2025, at a price of $10.00 per share (or $9.9999 per pre-funded warrant), substantially higher than the current market price of $6.31.

• Potential Market Overhang

  The registration of these shares for resale by institutional investors, including Samsara BioCapital, RTW Investments, and Coastlands Capital, could create selling pressure on the stock.

This 424B3 filing finalizes the registration for the resale of 5,000,000 shares by selling stockholders, enabling them to sell these shares into the market. This follows the S-3 registration statement filed on April 3, 2026. While the company itself will not receive proceeds from these sales (except for warrant exercises), the potential influx of shares from institutional investors, who acquired them at a significantly higher price of $10.00 per share in December 2025 compared to the current market price of $6.31, could create downward pressure on the stock. This is a significant event due to the volume of shares relative to the company's market capitalization and the substantial discount at which these shares are now trading compared to their original purchase price.
