Ironwood Pharmaceuticals Announces Proposed Offering of $300 Million of Convertible Senior Notes

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Ironwood Pharmaceuticals, Inc. (NASDAQ: IRWD) today announced that it intends to offer, subject to market and other conditions, $300 million aggregate principal amount of convertible senior unsecured notes that will mature on June 15, 2022 (the Notes). The Notes will be offered and sold to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. Ironwood also expects to grant the initial purchasers of the Notes an option to purchase up to an additional $45 million aggregate principal amount of the Notes solely to cover over-allotments.

The Notes will bear cash interest, payable on June 15 and December 15 of each year, beginning on December 15, 2015. The Notes will not be redeemable prior to maturity. The Notes will be convertible, only during certain periods and subject to certain circumstances, into cash, shares of Ironwood Class A common stock, or a combination of cash and shares of Ironwood's Class A common stock, at Ironwood's election. Final terms of the Notes, including interest rate, conversion rate, conversion price, and certain other terms of the offering, will be determined at the time of pricing.

In connection with the pricing of the Notes, Ironwood also expects to enter into one or more privately negotiated convertible note hedge transactions and warrant transactions with certain financial institutions (the option counterparties) in order to reduce the potential dilution with respect to shares of Ironwood's Class A common stock upon any conversion of the Notes and/or offset any cash payments Ironwood is required to make in excess of the principal amount of converted Notes, in each case, up to a threshold amount. The warrant transactions could have a dilutive effect with respect to Ironwood's Class A common stock to the extent that the market price per share of Ironwood's Class A common stock, as measured under the terms of the warrant transactions, exceeds the applicable strike price of the warrants on any expiration date of the warrants, which is anticipated to be significantly higher than the closing price of Ironwood's Class A common stock on the date the warrants are issued. If the initial purchasers exercise their option to purchase additional Notes, Ironwood expects to enter into additional convertible note hedge and warrant transactions.

Ironwood intends to use the net proceeds of the offering to strengthen its balance sheet, improve its capital structure and to fund general corporate purposes, which may include the repayment or redemption of all or a portion of its outstanding indebtedness and the acquisition of, or investment in, businesses or other strategic assets, and to pay the cost of the convertible note hedge transactions (after such cost is partially offset by proceeds from the warrant transactions).

Ironwood has been advised that, in connection with the convertible note hedge and warrant transactions, the option counterparties or their respective affiliates expect to enter into various hedging transactions, including (without limitation) derivative transactions, with respect to Ironwood's Class A common stock and/or to purchase Ironwood's Class A common stock concurrently with or shortly after the pricing of the Notes. This activity could increase (or reduce the size of any decrease in) the market price of Ironwood's Class A common stock or the Notes at that time. In addition, the option counterparties and/or their respective affiliates may, from time to time, modify their hedge positions by entering into or unwinding various hedging positions, including (without limitation) derivative transactions, with respect to Ironwood's Class A common stock and/or purchase or sell Ironwood's Class A common stock or other securities of Ironwood in secondary market transactions (and are likely to do so during any observation period related to a conversion of the Notes). This activity could also cause a decrease or offset or avoid an increase in the market price of Ironwood's Class A common stock or the Notes.

The offer and sale of the Notes are not being registered under 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.
