Press Release

BOSTON--(BUSINESS WIRE)-- Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today reported consolidated financial results for the quarter ended September 30, 2014. Vertex reported total third quarter 2014 GAAP revenues of $179 million, including revenues of $127 million from KALYDECO^® (ivacaftor). The GAAP net loss for the third quarter of 2014 was $(170) million, or $(0.72) per share, which includes net charges of $84 million. The non-GAAP net loss for the third quarter of 2014 was $(86) million, or $(0.37) per share. The company also today provided updated financial guidance for total 2014 non-GAAP revenues, 2014 KALYDECO revenues and non-GAAP operating expenses. As of September 30, 2014, Vertex had $1.48 billion in cash, cash equivalents and marketable securities.

"With the recent progress across our research and development programs in cystic fibrosis and the expansion of the number of people being treated with KALYDECO, we have established a clear path for the future of our company," said Jeffrey Leiden, M.D., Ph.D., Chairman, President and Chief Executive Officer of Vertex. "We remain focused on investing in the discovery and development of new medicines for CF and other serious and rare diseases while increasing revenues to move us to profitability and drive earnings growth."

Research and Development Updates

In a press release issued on October 9, 2014, Vertex provided a comprehensive update on its research and development programs aimed at developing combinations of medicines to treat the underlying cause of cystic fibrosis (CF) for the majority of people with the disease. Vertex today provided the following updates:

KALYDECO^® (ivacaftor)

Availability of KALYDECO in Australia: In Australia, KALYDECO is expected to be listed on the Pharmaceutical Benefits Scheme (PBS) as of December 1, which will provide reimbursement for all eligible patients to begin and remain on treatment with KALYDECO. There are approximately 250 people age 6 years and older who are expected to be eligible for treatment with KALYDECO in Australia.

R117H Mutation: Based on data from a Phase 3 study, Vertex submitted a supplemental New Drug Application (sNDA) in the U.S. in June and a Marketing Authorization Application (MAA) variation in the E.U. in July for the approval of KALYDECO for use in people who have the R117H mutation. On October 21, the U.S. Food and Drug Administration's Pulmonary Allergy Drugs Advisory Committee (PADAC) voted 13-2 to recommend approval of KALYDECO in people with CF ages 6 and older who have the R117H mutation in the cystic fibrosis transmembrane regulatory (CFTR) gene, which is the indication being reviewed by the FDA. The FDA is not bound by the committee's recommendation, but often follows its advice.

Third Quarter 2014 Non-GAAP Financial Results

The third quarter 2014 non-GAAP financial results exclude stock-based compensation expense, costs related to the relocation of our corporate headquarters, hepatitis C revenues and costs and other adjustments. The third quarter 2013 non-GAAP financial results exclude stock-based compensation expense, expenses related to Alios (HCV), hepatitis C-related costs and other adjustments.

Total Non-GAAP Revenues: Total non-GAAP revenues for the third quarter of 2014 were $165.0 million, including $126.8 million in net product revenues from KALYDECO and $38.2 million from royalties and collaborative revenues, which includes revenues from a one-time payment of $30 million from Janssen related to the out-licensing of VX-787 for the treatment of influenza. The components of total non-GAAP revenues for the third quarter of 2014 were:

		Three Months Ended September 30, 2014

Collaborative revenues		33.5				(1.4		)		32.1
Total revenues		$	179.0			$	(14.0	)		$	165.0

• Net Product Revenues from KALYDECO: Vertex's third quarter 2014 net product revenues from KALYDECO were $126.8 million compared to $101.1 million for the third quarter of 2013. The increased revenues, compared to the third quarter of 2013, resulted primarily from the use of KALYDECO in the U.S. in people with the additional mutations approved by the FDA in February 2014 and from an increase of approximately $7 million that resulted from changes in Vertex's distribution network.

Non-GAAP Operating Expenses: Total non-GAAP operating expenses for the third quarter of 2014 were $212.4 million, compared to $274.7 million for the third quarter of 2013. This reduction was primarily the result of prioritization of investment toward medicines for CF resulting in decreased R&D and SG&A expenses as follows:

• Research and Development (R&D) Expenses: Non-GAAP R&D expenses were $157.4 million for the third quarter of 2014, compared to $200.3 million in non-GAAP R&D expenses for the third quarter of 2013.
• Sales, General and Administrative (SG&A) Expenses: Non-GAAP SG&A expenses were $55.1 million for the third quarter of 2014, compared to $74.4 million in non-GAAP SG&A expenses for the third quarter of 2013.

Non-GAAP Net Income (Loss) Attributable to Vertex: Vertex's third quarter 2014 non-GAAP net loss was $(86.2) million, or $(0.37) per diluted share, compared to a non-GAAP net loss of $(74.4) million, or $(0.32) per diluted share, for the third quarter of 2013. The increased non-GAAP net loss for the third quarter of 2014 was primarily the result of a reduction in INCIVEK net product revenues, partially offset by increased KALYDECO product revenues, decreased operating expenses and the revenues from a one-time payment of $30 million from Janssen related to the out-licensing of VX-787.

Cash Position at September 30, 2014

As of September 30, 2014, Vertex had $1.48 billion in cash, cash equivalents and marketable securities compared to $1.47 billion in cash, cash equivalents and marketable securities as of December 31, 2013. In July 2014, Vertex entered into a credit agreement that provides for a secured loan of up to $500 million, $300 million of which Vertex received in July 2014 and is outstanding as of September 30, 2014.

2014 Financial Guidance

This section contains forward-looking guidance about the financial outlook for Vertex Pharmaceuticals.

On May 1, 2014, Vertex provided guidance for 2014 total non-GAAP revenues of $520 to $550 million, including total 2014 KALYDECO net product revenues of $470 to $500 million. The company now expects total non-GAAP revenues to be $525 to $535 million, with KALYDECO net product revenues expected to be approximately $460 million. The KALYDECO net product revenues range was based on assumptions of the timing of label expansion and reimbursement approvals in certain countries, and the company now expects KALYDECO revenues to be below the range provided in May due primarily to the delay in the reimbursement of KALYDECO in Australia.

Additionally, Vertex provided guidance for 2014 total non-GAAP operating expenses of $890 to $930 million. 2014 total non-GAAP operating expenses are now expected to be approximately $910 to $920 million, which reflects ongoing activities to support the accelerated advancement of VX-661 into a pivotal program in the first half of 2015.

Non-GAAP Financial Measures

In this press release, Vertex's financial results and financial guidance are provided in accordance with accounting principles generally accepted in the United States (GAAP) and using certain non-GAAP financial measures. In particular, non-GAAP financial results exclude: (i) in 2014, stock-based compensation expense, costs related to the relocation of the company's corporate headquarters including a one-time cash payment received related to a lease agreement, hepatitis C revenues and costs and other adjustments and (ii) in 2013, stock-based compensation expense, expenses related to Alios (HCV), the impairment of VX-222, hepatitis C inventory charges and costs, certain interest expenses related to the convertible notes due 2015 and other adjustments. These results are provided as a complement to results provided in accordance with GAAP because management believes these non-GAAP financial measures help indicate underlying trends in the company's business, are important in comparing current results with prior period results and provide additional information regarding the company's financial position. Management also uses these non-GAAP financial measures to establish budgets and operational goals that are communicated internally and externally and to manage the company's business and to evaluate its performance. A reconciliation of the GAAP financial results to non-GAAP financial results is included in the attached financial information.

INDICATION AND IMPORTANT SAFETY INFORMATION FOR KALYDECO (ivacaftor)

Ivacaftor (150 mg tablets) is indicated for the treatment of cystic fibrosis (CF) in patients age 6 years and older who have a G551D mutation in the CFTR gene.

In the United States, ivacaftor is also indicated for the treatment of CF in patients age 6 and older who have one of the following mutations in the CFTR gene: G1244E, G1349D, G178R, G551S, S1251N, S1255P, S549N, or S549R. In Canada, ivacaftor is indicated for these same mutations and additionally for G970R.

Ivacaftor is not effective in patients with CF with 2 copies of the F508del mutation (F508del/F508del) in the CFTR gene. The safety and efficacy of ivacaftor in children with CF younger than 6 years of age have not been established.

Elevated liver enzymes (transaminases; ALT and AST) have been reported in patients receiving ivacaftor. It is recommended that ALT and AST be assessed prior to initiating ivacaftor, every 3 months during the first year of treatment, and annually thereafter. Patients who develop increased transaminase levels should be closely monitored until the abnormalities resolve. Dosing should be interrupted in patients with ALT or AST of greater than 5 times the upper limit of normal. Following resolution of transaminase elevations, consider the benefits and risks of resuming ivacaftor dosing.

Use of ivacaftor with medicines that are strong CYP3A inducers, such as the antibiotics rifampin and rifabutin; seizure medications (phenobarbital, carbamazepine, or phenytoin); and the herbal supplement St. John's Wort, substantially decreases exposure of ivacaftor and may diminish effectiveness. Therefore, co-administration is not recommended.

The dose of ivacaftor must be adjusted when used concomitantly with strong and moderate CYP3A inhibitors or when used in patients with moderate or severe hepatic disease.

Ivacaftor can cause serious adverse reactions including abdominal pain and high liver enzymes in the blood. The most common side effects associated with ivacaftor include headache; upper respiratory tract infection (the common cold), including sore throat, nasal or sinus congestion, and runny nose; stomach (abdominal) pain; diarrhea; rash; and dizziness. These are not all the possible side effects of ivacaftor. A list of the adverse reactions can be found in the product labeling for each country where ivacaftor is approved. Patients should tell their healthcare providers about any side effect that bothers them or does not go away.

Indication and Important Safety Information for INCIVEK (telaprevir)

INCIVEK® (telaprevir) is a prescription medicine used with the medicines peginterferon alfa and ribavirin to treat chronic (lasting a long time) hepatitis C genotype 1 infection in adults with stable liver problems, who have not been treated before or who have failed previous treatment. It is not known if INCIVEK is safe and effective in children under 18 years of age.

Important Safety Information

INCIVEK® (telaprevir) should always be used in combination with peginterferon alfa and ribavirin. INCIVEK combination treatment may cause serious side effects including skin rash and serious skin reactions, anemia (low red blood cell count) that can be severe, and birth defects or death of an unborn baby.

Skin rashes are common with INCIVEK combination treatment. Sometimes these skin rashes and other skin reactions can become serious, require treatment in a hospital, and may lead to death. Patients should call their healthcare provider right away if they develop any skin changes or itching during treatment with INCIVEK. Their healthcare provider will decide if they need treatment or if they need to stop INCIVEK or any of their other medicines. Patients should not stop taking INCIVEK combination treatment without talking with their healthcare provider first.

Patients' healthcare providers will do blood tests regularly to check for anemia. If anemia is severe, the healthcare providers may tell them to stop taking INCIVEK.

INCIVEK combined with peginterferon alfa and ribavirin may cause birth defects or death of an unborn baby. Therefore, a patient should not take INCIVEK combination treatment if she is pregnant or may become pregnant, or if he is a man with a sexual partner who is pregnant. Females who can become pregnant and females whose male partner takes these medicines must have a negative pregnancy test before starting treatment, every month during treatment, and for 6 months after treatment ends. Patients must use two forms of effective birth control during treatment and for 6 months after all treatment has ended. These two forms of birth control should not contain hormones, as these may not work during treatment with INCIVEK.

INCIVEK and other medicines can affect each other and can also cause side effects that can be serious or life-threatening. There are certain medicines patients cannot take with INCIVEK combination treatment. Patients should tell their healthcare providers about all the medicines they take, including prescription and over-the-counter medicines, vitamins and herbal supplements.

The most common side effects of INCIVEK combination treatment include itching, nausea, diarrhea, vomiting, anal or rectal problems (including hemorrhoids, discomfort, burning or itching around or near the anus), taste changes and tiredness. There are other possible side effects of INCIVEK, and side effects associated with peginterferon alfa and ribavirin also apply to INCIVEK combination treatment. Patients should tell their healthcare provider about any side effect that bothers them or doesn't go away.
