Repligen issues $1.0 billion of 0.25% convertible notes due 2031 in exchange and cash deals

Neutral financing 1.012.033.02

Repligen closed private exchange and subscription transactions on November 6, 2026, issuing $1.0 billion of 0.25% Convertible Senior Notes due 2031. About $541.4 million of the new notes swapped out $456.8 million of its 1.00% notes due 2028, and $458.6 million was sold for cash. The filing shows the company took on new debt with a lower coupon and a conversion price about 20% above the October 29, 2026 closing price, which could mean future share dilution if holders convert.

  • Issued $1.0 billion of 0.25% Convertible Senior Notes due November 1, 2031, with interest paid semi-annually starting May 1, 2027
  • Exchanged $456.8 million of 1.00% 2028 notes for $541.4 million of new notes; $143.2 million of 2028 notes remain outstanding
  • Initial conversion price of about $226.37 per share, roughly 20% above the $188.64 closing price on October 29, 2026
  • Up to 5,301,100 shares of common stock may be issued on conversion, including make-whole additional shares
