GSK announces Proposed Unregistered Offering of Senior Notes Exchangeable into Theravance Biopharma Ordinary Shares

GlaxoSmithKline plc ("GSK"), acting through its subsidiary GSK Finance (No.3) plc (“the issuer”) announced today its intention to offer senior notes due 2023 (“the notes”) exchangeable into ordinary shares of Theravance Biopharma, Inc. (“Theravance Biopharma”) currently held by GSK and its affiliates.  The notes will be guaranteed by GSK and will be exchangeable at the option of noteholders during specified periods. The notes will not bear a coupon.

The notes will be exchangeable into substantially all of the 9,644,807 ordinary shares of Theravance Biopharma currently held by GSK and its affiliates. Upon exchange of the notes, the issuer expects to deliver ordinary shares of Theravance Biopharma but may, at its option under certain circumstances, deliver cash or a combination of Theravance Biopharma shares and cash. The exchange premium will be set at pricing. In connection with the offering, Theravance Biopharma will agree to file a shelf registration statement with the U.S. Securities and Exchange Commission (the “SEC”) to register resales of its ordinary shares deliverable upon exchange of the notes.

GSK expects to use the net proceeds of the offering for general corporate purposes.  Theravance Biopharma will not receive any proceeds from the offering.

The offering of the notes will not be registered under the U.S. Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws and, unless so registered, may not be offered or sold in the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws. The notes will be offered by means of an offering memorandum solely to persons reasonably believed to be “qualified institutional buyers” (as that term is defined in Rule 144A under the Securities Act) that are also “qualified purchasers” (within the meaning of Section 2(a)(51) of the U.S. Investment Company Act of 1940, as amended). This press release does not constitute an offer to sell or the solicitation of an offer to buy the notes nor shall there be any sale of notes in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such state.

This communication is only being distributed to and is only directed at (i) persons who are outside the United Kingdom (the “UK”) or (ii) investment professionals falling within Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 (the “Order”) or (iii) high net worth companies, and other persons to whom it may lawfully be communicated, falling within Article 49(2)(a) to (d) of the Order (all such persons together being referred to as “relevant persons”).  The notes are only available to, and any invitation, offer or agreement to subscribe, purchase or otherwise acquire such notes will be engaged in only with, relevant persons.  Any person who is not a relevant person should not act or rely on this document or any of its contents.

PROHIBITION OF SALES TO EEA AND UK RETAIL INVESTORS

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”) or in the UK. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II. Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA or in the UK has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA or in the UK may be unlawful under the PRIIPs Regulation.
