Global Blood Therapeutics Prices Upsized $345 Million Convertible Notes Offering with Capped Call

The Life Sciences IPOs + Capital Markets team advised Global Blood Therapeutics, Inc. (Nasdaq: GBT) on its offering of 1.875% Convertible Senior Notes due 2028. The deal initially launched at $250 million, but was upsized to $300 million, plus the full exercise of the initial purchasers’ option to purchase an additional $45 million of notes. The initial conversion price of the notes featured a premium of 27.5% up from the reference price of $24.90. In connection with the notes, Global Blood Therapeutics entered into capped call transactions which mitigate equity dilution and/or offset payments due upon conversion of the notes and effectively raises the conversion price of the notes to $49.80 per share, a 100% premium over the reference price.
