Non-Confidential Information – Horizon Pharma plc
This presentation contains forward-looking statements, including, but not limited to, statements related to the consummated business
combination transaction between Horizon Pharma, Inc. and Vidara Therapeutics  International plc and the benefits thereof, the strategy, plans,
objectives, expectations (financial or otherwise) and intentions, future financial results and growth potential of the combined company –
Horizon Pharma plc, development programs and management structure, and other statements that are not historical facts.  
This presentation also includes forward-looking statements regarding results of the Phase 2 clinical trial of ACTIMMUNE and management
expectations and plans regarding further study of ACTIMMUNE in Friedreich’s ataxia (FA) , related discussions with the FDA,  the potential for
ACTIMMUNE as a treatment for FA patients, and potential sales opportunity for ACTIMMUNE.   The statements made by representatives of the
Friedreich’s Ataxia Research Alliance and the Collaborative Clinical Research Network in Friedreich’s Ataxia represent their independent
conclusions and recommendations.  
These forward-looking statements are based on Horizon Pharma plc’s current expectations and inherently involve significant risks and
uncertainties.   Actual results and the timing of events could differ materially from those anticipated in such forward looking statements as a
result of these risks and uncertainties, which include, without limitation, risks related to future opportunities and plans for Horizon Pharma plc,
including uncertainty of the expected financial performance and results; disruption from the transaction, making it more difficult to conduct
business as usual or maintain relationships with customers, employees or suppliers; and the possibility that if Horizon Pharma plc does not
achieve the perceived benefits of the transaction as rapidly or to the extent anticipated by financial analysts or investors, the market price of its
shares could decline, as well as other risks related to Horizon Pharma plc’s business, including whether results of subsequent studies will be
consistent with results of the Phase 2 clinical trial of ACTIMMUNE; risks regarding timing and outcome of regulatory review and approval of
product candidates; its dependence on sales of its existing products and its ability to increase sales of its existing products; Horizon Pharma plc’s
ability to successfully execute its commercial strategy and achieve projected financial results in 2014 and 2015; the fact that past financial or
operating results are not a guarantee of future results; competition, including potential generic competition; the ability of Horizon Pharma plc to
protect its intellectual property and defend its patents; regulatory obligations and oversight; and those risks detailed from time-to-time under
the caption “Risk Factors” and elsewhere in Horizon Pharma plc’s  SEC filings and reports, including in its Annual Report on Form 10-K for the
year ended December 31, 2013.  Horizon Pharma plc undertakes no duty or obligation to update any forward-looking statements contained in
this presentation as a result of new information, future events or changes in its expectations.

Note Regarding Use of Non-GAAP Financial Measures
4
Horizon provides certain financial measures such as adjusted non-GAAP net income (loss), adjusted non-GAAP net income (loss) per share, non-
GAAP gross profit margins and non-GAAP cash from operations that include adjustments to GAAP figures.  These adjustments to GAAP exclude
acquisition transaction related expenses as well as non-cash items such as stock compensation, depreciation and amortization, accretion, non-
cash interest expense, and other non-cash adjustments such as the increase or decrease in the fair value of the embedded derivative associated
with the Company’s convertible senior notes.  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.  EBITDA, or earnings before interest, taxes,
depreciation and amortization, and adjusted EBITDA are also used and provided by Horizon as non-GAAP financial measures.  Horizon believes
that these non-GAAP financial measures, when considered together with the GAAP figures, can enhance an overall understanding of Horizon's
financial performance.  The non-GAAP financial measures are included with the intent of providing investors with a more complete
understanding of the Company’s operational results, trends and expectations.  In addition, these non-GAAP financial measures are among the
indicators Horizon’s management uses for planning and forecasting purposes and measuring the Company's performance.  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.  The Company has not provided a reconciliation of full year 2014 or 2015 adjusted
EBITDA outlook to a net income (loss) outlook because certain items that are a component of net income (loss) but not part of adjusted EBITDA,
such as the gain (loss) on derivative revaluation associated with the convertible senior notes, stock compensation, acquisition related expenses
and certain purchase accounting items such as intangibles and step-up inventory, cannot be reasonably projected, either due to the significant
impact of changes in Horizon’s stock price on derivative revaluation and stock compensation, or the variability associated with acquisition
related expenses and purchase accounting items due to timing and other factors.

FA & ACTIMMUNE Phase 2 Clinical Trial Results
Jennifer Farmer,  MS, Certified Genetic Counselor
Executive Director, FARA
Coordinator, Collaborative Clinical Research
Network in FA


Friedreich Ataxia (FA)
A rare, genetic condition that is a progressive
degenerative disease of children, adolescents and
adults
Affects 1 in 50,000
Estimated 4-5,000 individuals in US and 15,000
worldwide
Nicolaus Friedreich first described in 1860’s based on
6 patients from 2 families
Typically thought of as a neurodegenerative disease
as this is the most visible and common symptom;
however FA is a multi-system disease
Genotypic and phenotypic heterogeneity
16
Childhood onset is associated with more rapid progression.
Onset/symptoms appear between ages of 5-15 years
Late teens –
early twenties most individuals are wheelchair-bound
and require assistance with ADLs
Late onset (diagnosed after age 20) is associated with slower progression
and overall more mild phenotype


FA –
Clinical Features
Clinical features:  Neuro
Loss of large sensory neurons -
proprioception
Loss of balance and coordination
Loss of reflexes
Loss of spinocerebellar tracts
Loss of balance and coordination
Loss of motor tracts to a lesser degree
Loss of dentate nucleus of the cerebellum
Dysarthria (slurred speech), modest eye movement
abnormalities
Loss of a few other specific sites.
Vision, hearing loss
Sparing of cerebellar cortex, cerebral cortex
Normal cognition
Overall loss of relatively few neurons, modest number of
axonal tracts----MRI scans are normal or almost normal in
early disease
17


FA –
Not just Neuro but Multi-system condition
Heart:  Cardiomyopathy and arrhythmia
Hypertrophic cardiomyopathy can be
progressive and severe and early
morbidity and mortality
Clinically significant arrhythmia
Endo:  Diabetes –10-20%; >65% Insulin
resistance
ENT
Swallowing difficulty in later stage
patients
Hearing loss –
10-15% of patients
Ophthal
Optic atrophy –
present in 10% of pts
Fixation abnormalities common
(square wave jerks, ocular flutter)
Skeletal:  Scoliosis
-Corrective surgery required in up to
50% of patients
-Pes cavus
Fatigue:  Nearly all patients
experience significant fatigue that
impacts quality of life.
Cognition remains normal
18


Friedreich’s Ataxia:  Management
No treatment to stop progression of disease
Most individuals take vitamins and antioxidants
Annual Echocardiogram and EKG
Treat cardiac symptoms as they appear
No clinical treatment guidelines
Annual glucose
Annual scoliosis screening (especially kids ages 7-18)
Spinal fusion –
as needed
Annual vision and hearing screening
Annual PT/OT/Speech

Measured frataxin levels inversely correlates with GAA repeat
length, suggesting that the assay is useful for assessing severity of
disease in buccal cells.

Two Encouraging Learnings:  1) Individuals with FA

Why Interferon gamma for FA?

Why Interferon gamma for FA?
27


Why Interferon gamma for FA?
FRDA mice improve both locomotor activity and
motor coordination, when treated with IFN
, and
that this is paralleled by both frataxin upregulation
and neuronal preservation in DRG.

Clinical/Regulatory Considerations for FA
Clinical/Regulatory Considerations for FA
FA is a debilitating, life-shortening, ultra orphan disorder
(prevalence of 1 in 50,000 people in U.S.)
No treatment for patients only monitored for symptoms
Increase in initiatives and incentives from FDA to expedite
treatments for conditions such as FA
Rare and orphan disease programs
Expedited programs for serious conditions
Best Pharmaceuticals for Children Act (BPCA)
ACTIMMUNE already FDA approved for two debilitating,
orphan diseases
Supplement approval pathway typically more straightforward
than new entity approval

Chronic Granulomatous Disease (CGD) Overview
CGD was identified in the 1950’s
Survival has improved over time and
most patients are able to manage their
disease and can live well into adulthood
CGD is a disease of the immune system
and described as a primary
immunodeficiency disorder
CGD is the most  common disorder of 
phagocytes making up 6% of primary
immune deficiencies
~1 in every 200,000 babies are born
with CGD.  There are estimated to be
~1,600 CGD patients in the U.S.

ACTIMMUNE Clinical Benefit in CGD
ACTIMMUNE Clinical Benefit in CGD
Fewer Days of Hospitalization
Reduction in Relative Risk of Serious Infections
Non-Confidential Information – Horizon Pharma plc
* Serious infection was defined as an infection requiring hospitalization and parenteral antibiotics 
**The beneficial effect of ACTIMMUNE was demonstrated throughout a 12 month study
67% reduction in relative risk of serious
infection* in patients receiving ACTIMMUNE
(p=0.0006)
64% reduction in total number of serious
infections* (p<0.0001)
Placebo patients required 3x as many inpatient
hospitalization days for treatment of clinical
events compared to patients receiving
ACTIMMUNE (p=0.02)
77% of patients receiving ACTIMMUNE were
free of serious infections vs. 30% receiving
placebo. ** (P= 0.0006). 
The mean duration of
therapy for these patients was 8.9 months
A long-term observational follow-up study of
patients who received adjunctive prophylactic
therapy with ACTIMMUNE demonstrated an
incidence of 0.30 serious infections* per
patient-year


Severe Malignant Osteopetrosis (SMO) Overview
SMO is a one form of osteopetrosis and is sometimes referred to as
marble bone disease or malignant infantile osteopetrosis (MIOP)
Often misdiagnosed as hematologic cancer
~1 in every 250,000 babies are born with SMO 
There are estimated to be ~200 SMO patients in the U.S.

Neurological Examinations and Genetic Testing
Lead to Specialized Care Centers
74
Patients are typically referred by
their primary provider to
neurologists (including pediatric
neurologists) for evaluation and
diagnosis of FA
FA is typically suspected after a
neurological exam, though
genetic testing of frataxin is
needed for definitive diagnosis
KOLs estimate two thirds of FA
patients will eventually receive
care at a center that specializes in
muscular dystrophies, FA or
general ataxias
