PRESS RELEASE

THERAVANCE ANNOUNCES CLOSING OF PUBLIC OFFERING OF
$287.5 MILLION OF CONVERTIBLE SUBORDINATED NOTES

SOUTH SAN FRANCISCO, CA. — January 24, 2013 — Theravance, Inc. (NASDAQ: THRX) (the “Company”), a biopharmaceutical company with a pipeline of internally discovered product candidates and strategic collaborations with pharmaceutical companies, announced that it closed the sale of its previously announced underwritten public offering of $287.5 million aggregate principal amount of its 2.125% convertible subordinated notes due 2023 (the “notes”), which includes the underwriters’ full exercise of their option to purchase an additional $37.5 million aggregate principal amount of the notes. BofA Merrill Lynch acted as the sole book-running manager for the offering.

In connection with the offering of the notes, the Company entered into privately-negotiated capped call option transactions.  The aggregate cost of the capped call options was $36.8 million.

The capped call options are expected generally to reduce the potential dilution upon conversion of the notes in the event that the market price of the Company’s common stock, as measured under the terms of the capped call transactions, is greater than the strike price of the capped call transactions, which initially corresponds to the conversion price of the notes, and is expected to be subject to customary anti-dilution adjustments.  However, if the market price of the Company’s common stock, as measured under the terms of the capped call transactions, exceeds $38.00 per share, which is the initial cap price of the capped call transactions, the anti-dilutive effect of the capped call transactions will be limited.

In addition to paying for the cost of entering into the capped call option transactions, the Company intends to use the net proceeds of the offering for potential milestone payments to GlaxoSmithKline plc if there is any approval or launch of products under the parties’ long-acting beta2 agonist (LABA) collaboration, including RELVAR™ or BREO™ (fluticasone furoate/vilanterol), ANORO™ (umeclidinium bromide/vilanterol), or vilanterol, for the potential repayment of debt, and for other general corporate purposes.

This press release is neither an offer to sell nor a solicitation of an offer to buy any securities and shall not constitute an offer, solicitation or sale in any jurisdiction in which such offer, solicitation or sale is unlawful.

The offering was made pursuant to a registration statement filed with the U.S. Securities and Exchange Commission (the “SEC”) on January 16, 2013 and including a final prospectus dated January 17, 2013 filed with the SEC on January 18, 2013.
