Ironwood Pharmaceuticals Announces Full Exercise of Convertible Notes Over-Allotment

CAMBRIDGE, Mass.--(BUSINESS WIRE)--

Ironwood Pharmaceuticals, Inc. (“Ironwood”) (IRWD), a GI-focused healthcare company, today announced that, in connection with its previously announced offering of 0.75% Convertible Senior Notes due 2024 (the “2024 Notes”) and 1.50% Convertible Senior Notes due 2026 (the “2026 Notes” and, together with the 2024 Notes, the “Notes”), the initial purchaser exercised in full its option to purchase $25 million aggregate principal amount of the 2024 Notes and $25 million aggregate principal amount of the 2026 Notes (the “Additional Notes”).

Ironwood estimates that the net proceeds of the offering will be approximately $390 million (including the previously announced net proceeds of approximately $341 million from the initial closing of the offering of Notes, which occurred on August 12, 2019) after deducting the initial purchaser’s discounts and commissions, but prior to deducting estimated offering expenses. Ironwood plans to use approximately $3 million of the net proceeds from the offering of the Additional Notes to pay the cost of additional capped call transactions entered into in connection with the exercise of the initial purchaser’s option. The cap price of the capped call transactions will initially be approximately $17.05 per share, which represents a premium of approximately 75% over the last reported sale price of Ironwood Class A common stock of $9.74 per share on August 7, 2019, and is subject to certain adjustments under the terms of the capped call transactions.

Ironwood intends to use the remaining net proceeds, together with cash on hand, to redeem all of its outstanding 8.375% Notes due 2026, repurchase approximately $215 million aggregate principal amount of its outstanding 2.25% Convertible Notes due 2022, and, to the extent additional proceeds are available, fund general corporate purposes.

The offer and sale of the Notes has not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws. The Notes may not be offered or sold in the United States except pursuant to an exemption from the registration requirements of the Securities Act and any applicable state securities laws.

This news release does not constitute an offer to sell or a solicitation of an offer to buy the securities described herein, nor shall there be any sale of these securities, in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the laws of such jurisdiction.
