Item 8.01 Other Events.

Exhibit 99.1 to this Form 8-K is Theravance, Inc.'s current investor presentation and is incorporated by reference herein.

With regard to expense guidance for 2013, we currently anticipate that total 2013 Research and Development expenses plus Selling, General and Administrative expenses will be in the range of $125 million to $135 million. This guidance does not include stock-based compensation expense or any milestone payments to GlaxoSmithKline plc (GSK) under our long-acting beta2 agonist (LABA) collaboration with GSK.

Our expectations regarding our expenses for 2013 are forward-looking statements based solely on management estimates utilizing currently available information. As described below under "Note Regarding Forward-Looking Statements," investors are cautioned that forward-looking statements are not guarantees of future performance and involve significant risks and uncertainties, and that actual results may differ materially from those projected in the forward-looking statements. Our independent registered public accounting firm has not audited, reviewed or performed any procedures with respect to these expected expenses and, accordingly, does not express an opinion or any other form of assurance with respect to these expectations.

Examples of such statements include statements relating to expense guidance for 2013, the status and timing of clinical studies, data analysis and communication of results, statements regarding the potential benefits and mechanisms of action of drug candidates, statements concerning the timing of seeking regulatory approval of our product candidates (including, with respect to VIBATIV®, statements regarding any expectation that we will be able to respond fully or adequately to the FDA's requests using currently existing clinical data and any expectation that the FDA will approve the VIBATIV® nosocomial pneumonia NDA on the basis of existing preclinical and clinical data or at all), statements concerning the enabling capabilities of our approach to drug discovery and its proprietary insights, statements concerning expectations for the discovery, development and commercialization of product candidates and projections of revenue, expenses and other financial items.
