DUBLIN, IRELAND – Aug. 7, 2017 – Horizon Pharma plc (NASDAQ: HZNP), a biopharmaceutical company focused on improving patients’ lives by identifying, developing, acquiring and commercializing differentiated and accessible medicines that address unmet medical needs, announced its second-quarter and year-to-date 2017 financial results today and increased its full-year 2017 net sales and adjusted EBITDA guidance.

“Our rare disease medicines generated another quarter of strong performance, increasing 70 percent versus a year ago,” said Timothy P. Walbert, chairman, president and chief executive officer, Horizon Pharma plc. “As a result of strong second-quarter performance across our business units, we are raising our full-year sales and adjusted EBITDA guidance.”

Mr. Walbert added, “We also made multiple advancements during the quarter, positioning Horizon Pharma as a sustainable biopharmaceutical company focused on rare disease medicines, including the addition of teprotumumab, a biologic in late-stage development for thyroid eye disease, a rare eye disease, which represents an important step in building our development pipeline to drive long-term growth.”

Company Highlights

• Second-quarter net sales were $289.5 million, an increase of 12 percent compared to the second quarter of 2016, driven by continued strong growth from the Company’s orphan and rheumatology business units.

• Second-quarter net sales of Horizon Pharma’s medicines for rare diseases, which include RAVICTI^®, PROCYSBI^®, KRYSTEXXA^®, ACTIMMUNE^®, BUPHENYL^® and QUINSAIR™, increased 70 percent compared to the second quarter of 2016. Net sales of the Company’s rare disease medicines represented 55 percent of total net sales compared to 36 percent in the second quarter of 2016.

• The Company completed the acquisition of River Vision and its biologic, teprotumumab, on May 8, 2017. Teprotumumab is in late-stage development to treat thyroid eye disease (TED), a rare, debilitating and painful condition with no FDA-approved therapy. With a significant unmet treatment need for TED, the Company anticipates a potential peak annual net sales opportunity for teprotumumab, if approved, of more than $250 million in the United States. The acquisition marks an important first step toward assembling a portfolio of development-stage, rare disease medicines.

• The Company completed the sale of the marketing rights for PROCYSBI and QUINSAIR in the Europe, the Middle East and Africa (EMEA) regions to Chiesi Farmaceutici S.p.A. on June 23, 2017.

• Health Canada approved PROCYSBI for use in Canada on June 19, 2017. PROCYSBI is the only cystine-depleting agent approved in Canada for the treatment of nephropathic cystinosis and is expected to launch by the end of the year.

2

• Four new KRYSTEXXA data analyses were presented at the 2017 Annual European Congress of Rheumatology (EULAR) in evaluating the use of KRYSTEXXA in patients with refractory chronic gout. A new study underscoring the burden of gout on patients and the healthcare system was also presented at EULAR. The study findings showed that U.S. gout-related hospitalizations have increased 410 percent since 1993, and that hospitalizations in patients with gout resulted in costs in 2014 of more than $42.6 billion. These presentations support the Company’s continued efforts to address the lack of awareness and understanding regarding refractory chronic gout and the benefits of KRYSTEXXA.

• The Company received approval from the U.S. Food and Drug Administration (FDA) for a supplemental New Drug Application (sNDA) for RAVICTI on April 28, 2017. The sNDA expands the age range for chronic management of urea cycle disorders (UCDs) in patients to two months of age and older, from the previous age range of two years of age and older.

• Two intellectual property-related developments of note occurred during the second quarter. In May, the U.S. District Court for the District of New Jersey upheld the validity of a patent covering PENNSAID^® 2% that expires in 2027. In June, the U.S. District Court for the District of New Jersey upheld the validity of two Horizon Pharma patents covering VIMOVO^® that expire in 2022 and 2023. Both medicines have numerous Orange Book-listed patents that extend out to 2030 and beyond.

(1) PROCYSBI and QUINSAIR were acquired on Oct. 25, 2016. Q2 16 pre-acquisition net sales of PROCYSBI and QUINSAIR were $31.4 million and $0.7 million respectively.

(2) On June 23, 2017, Horizon Pharma completed the divestiture of a European subsidiary that owns the marketing rights to PROCSYBI and QUINSAIR in Europe, the Middle East and Africa to Chiesi Farmaceutici S.p.A. Horizon Pharma retains marketing rights for the two medicines in the U.S., Canada, Latin America and Asia.

• Orphan Business Unit: Second-quarter net sales for the orphan business unit increased 64 percent compared to the second quarter of 2016. Driving the results were strong net sales performance of RAVICTI and PROCYSBI.

RAVICTI net sales in the second quarter of 2017 were $47.2 million, an increase of 20 percent compared to the second quarter of 2016, driven by continued conversion from older-generation nitrogen-scavenger therapies, as well as the addition of treatment-naïve patients, in part resulting from the FDA approval of the sNDA for RAVICTI on April 28, 2017. The Company continues to expect RAVICTI to be launched in Europe in the second half of 2017 in partnership with Swedish Orphan Biovitrum AB (SOBI).

PROCYSBI net sales in the second quarter of 2017 were $36.7 million, an increase of 17 percent compared to pre-acquisition net sales of $31.4 million in the second quarter of 2016, driven by demand from both patients converting from older-generation therapy as well as from treatment-naïve patients. The differentiated profile of PROCYSBI was highlighted in July at the Cystinosis Research Network 2017 Family Conference in a presentation that demonstrated that patients receiving PROCYSBI had a 26 percent reduction in a metabolite associated with halitosis (i.e., bad breath) compared to those receiving immediate-release cysteamine. This is an important consideration for people living with cystinosis.

ACTIMMUNE net sales in the second quarter of 2017 were $28.8 million, a decrease of 4 percent versus the second quarter of 2016 and an increase of 10 percent sequentially from the first quarter of 2017. This increase was in part due to the Company’s evolved strategy to establish the role of ACTIMMUNE in a broader range of chronic granulomatous disease patients.

The investigator-initiated Fox Chase Cancer Center Phase 1 dose-escalation trial, which is evaluating ACTIMMUNE as part of a combination therapy in solid tumors for certain cancers, continues to advance. In addition, a National Cancer Institute Phase 2 study evaluating a different cancer combination therapy using ACTIMMUNE remains on track to begin later in 2017. A third cancer combination study is also underway with the Moffitt Cancer Center and Research Institute evaluating ACTIMMUNE and other cancer therapies in certain advanced breast cancer patients.

The second-quarter acquisition of teprotumumab expands and diversifies the Company’s rare disease medicine pipeline. The recently completed Phase 2 clinical trial of teprotumumab demonstrated unprecedented clinical efficacy in the treatment of TED. The results of the multicenter, double-blind, randomized placebo-controlled trial, which lasted 24 weeks and involved 88 patients, were published in The New England Journal of Medicine in May. In the intention-to-treat population, 29 of 42 patients who received teprotumumab (69 percent), as compared with 9 of 45 patients who received placebo (20 percent), had a response at week 24 (p<0.001). The primary end point was the response in the study eye; this response was defined as a reduction of 2 points or more in the Clinical Activity Score (scores range from 0 to 7, with a score of ³3 indicating active thyroid eye disease) and a reduction of 2 mm or more in proptosis at week 24. The Company remains on track to begin the confirmatory Phase 3 trial by year end.

• Rheumatology Business Unit: Second-quarter net sales for the rheumatology business unit were $51.7 million, an increase of 56 percent compared to the second quarter of 2016, driven by KRYSTEXXA. KRYSTEXXA net sales in the second quarter of 2017 were $38.3 million, an increase of 93 percent compared to the second quarter of 2016, driven in part by continued strong year-over-year vial demand.

The Company announced during the second quarter that, based on the continued increase in uptake of KRYSTEXXA and the clear unmet need for thousands of refractory chronic gout sufferers, the Company is significantly increasing its commercial infrastructure and investment in the medicine. This is in support of the Company’s expectation for annual peak net sales for KRYSTEXXA of more than $400 million versus the previous estimate of more than $250 million. During the second quarter, the Company began its initiative to expand its rheumatology business unit’s commercial organization to nearly 200 employees from more than 100, with the objective of reaching more physicians and increasing awareness of refractory chronic gout among physicians and patients. The expansion is expected to be complete by the end of the year.

• Primary Care Business Unit: Total second-quarter net sales for the primary care business unit were $117.4 million, a decrease of 22 percent compared to the second quarter of 2016, due to the implementation of the new contracting model with pharmacy benefit managers. Second-quarter 2017 net sales improved sequentially over first-quarter 2017 net sales as a result of higher average net realized price (ANRP) and improved prescription demand.

Note Regarding Use of Non-GAAP Financial Measures

EBITDA, or earnings before interest, taxes, depreciation and amortization, and adjusted EBITDA are used and provided by Horizon Pharma as non-GAAP financial measures. Horizon Pharma provides certain other financial measures such as non-GAAP net income, non-GAAP diluted earnings per share, non-GAAP gross profit and gross profit ratio, non-GAAP operating expenses, non-GAAP tax rate and non-GAAP operating cash flow, each of which include adjustments to GAAP figures. These non-GAAP measures are intended to provide additional information on Horizon Pharma’s performance, operations, expenses, profitability and cash flows. Adjustments to Horizon Pharma’s GAAP figures as well as EBITDA exclude acquisition-related expenses, charges related to the discontinuation of ACTIMMUNE development for Friedreich’s ataxia, gain from divestiture, an upfront fee for a license of a patent, a litigation settlement, loss on debt extinguishment, loss on sale of long-term investments, costs of debt refinancing, drug manufacturing harmonization costs, as well as non-cash items such as share-based compensation, depreciation and amortization, royalty accretion, non-cash interest expense, intangible and other non-current asset impairment charges, and other non-cash adjustments. Certain other special items or substantive events may also be included in the non-GAAP adjustments periodically when their magnitude is significant within the periods incurred. Horizon maintains an established non-GAAP cost policy that guides the determination of what costs will be excluded in non-GAAP measures. Horizon Pharma believes that these non-GAAP financial measures, when considered together with the GAAP figures, can enhance an overall understanding of Horizon Pharma’s financial and operating performance. The non-GAAP financial measures are included with the intent of providing investors with a more complete understanding of the Company’s historical and expected 2017 financial results and trends and to facilitate comparisons between periods and with respect to projected information. In addition, these non-GAAP financial measures are among the indicators Horizon Pharma’s management uses for planning and forecasting purposes and measuring the Company’s performance. For example, adjusted EBITDA is used by Horizon Pharma as one measure of management performance under certain incentive compensation arrangements. These non-GAAP financial measures should be considered in addition to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. The non-GAAP financial measures used by the Company may be calculated differently from, and therefore may not be comparable to, non-GAAP financial measures used by other companies. Horizon Pharma has not provided a reconciliation of its full-year 2017 adjusted EBITDA outlook to an expected net income (loss) outlook because certain items such as acquisition-related expenses and share-based compensation that are a component of net income (loss) cannot be reasonably projected due to the significant impact of changes in Horizon Pharma’s stock price, the variability associated with the size or timing of acquisitions and other factors. These components of net income (loss) could significantly impact Horizon Pharma’s actual net income (loss).
