OUR BUSINESS



We are a global biotechnology company focused on the discovery, development and
commercialization of medicines that address critical needs for people impacted
by rare, autoimmune and severe inflammatory diseases. Our pipeline is
purposeful: we apply scientific expertise and courage to bring clinically
meaningful therapies to patients. We believe science and compassion must work
together to transform lives. We have two reportable segments, the orphan segment
and the inflammation segment, and our commercial portfolio is currently composed
of 12 medicines in the areas of rare diseases, gout, ophthalmology and
inflammation.

Impact of COVID-19



The COVID-19 pandemic has continued to have a negative impact on our operations
and net sales during 2022, including due to the emergence of new variants of the
virus and resulting disruptions in healthcare operations and employee absences
among our commercial team. In addition, our clinical trials have been and may in
the future be affected by the COVID-19 pandemic as referred to below.

Economic and health conditions in the United States and across most of the world
are continuing to change because of the COVID-19 pandemic. Although COVID-19 is
a global issue that has altered business and consumer activity, the
biopharmaceutical industry is considered a critical and essential industry in
the United States and many other countries and, therefore, we do not currently
expect any government-imposed extended shut downs of suppliers or distribution
channels, although our suppliers and other third parties on which we rely could
be impacted by employee absences due to COVID-19 illnesses. While certain of our
contract manufacturers are involved in manufacturing vaccines for COVID-19, we
do not currently expect these activities to impact the future supply of our
medicines. In respect of our medicines, we believe we have sufficient inventory
of raw materials and finished goods and we expect patients to be able to
continue to receive their medicines at a site of care, for our infused
medicines, and from their current pharmacies, alternative pharmacies or, if
necessary, by direct shipment from our third-party providers that have such
capability, for our other medicines.

TEPEZZA, KRYSTEXXA and UPLIZNA



In the first half of 2022, demand for TEPEZZA, KRYSTEXXA and UPLIZNA was
negatively impacted by the omicron variant of COVID-19. The omicron variant
resulted in significant employee absences in our commercial organization due to
illness and also impacted operations at sites of care that infuse these
medicines and patient access to and willingness to visit healthcare providers.
These events resulted in lower new patient enrollment forms, delays in new
patients starting infusions and disruptions in therapy. These same events also
impacted enrollment in the TEPEZZA clinical trial for chronic/low clinical
activity score, or CAS, thyroid eye disease, or TED, and we now expect data from
this trial in the first half of 2023. In addition, enrollment in our clinical
trial of UPLIZNA in myasthenia gravis was recently impacted by the COVID-19
related lock-downs in China which, combined with other negative impacts related
to the conflict in Ukraine, has delayed our expected timeline for topline data
to 2024.

Our other medicines

Patient motivation to continue treatment remains high for our other orphan
segment medicines, RAVICTI, PROCYSBI and ACTIMMUNE, and therefore net sales for
these three medicines were stable during 2020, 2021 and the first half of 2022,
with less impact from COVID-19 compared to our other medicines.

Clinical trials



Our clinical trials have been and may in the future be affected by COVID-19. As
referred to above, we experienced enrollment delays in our TEPEZZA clinical
trial in chronic/low CAS TED due to the impacts of the omicron variant of
COVID-19 and in our UPLIZNA clinical trial in myasthenia gravis due to
government ordered COVID-19 lock-downs in China. In addition, clinical site
initiation and patient enrollment may be delayed due to staffing shortages or
prioritization of hospital and healthcare resources toward COVID-19. Current or
potential patients in our ongoing or planned clinical trials may also choose to
not enroll, not participate in follow-up clinical visits or drop out of the
trial as a result of, or a precaution against, contracting COVID-19. Further,
some patients may not be able or willing to comply with clinical trial protocols
if healthcare services are interrupted due to COVID-19. Some clinical sites in
the United States and other countries have slowed or stopped further enrollment
of new patients in clinical trials, denied access to site monitors or otherwise
curtailed certain operations. Similarly, our ability to recruit and retain
principal investigators and site staff who, as healthcare providers, may have
heightened exposure to COVID-19, may be adversely impacted. These events could
delay our clinical trials, increase the cost of completing our clinical trials
and negatively impact the integrity, reliability or robustness of the data from
our clinical trials.

We are continuing to actively monitor the possible impacts from the COVID-19
pandemic, including the emergence of new variants of the virus such as omicron
subvariants, and may take further actions to alter our business operations as
may be required by federal, state or local authorities or that we determine are
in the best interests of patients, healthcare providers and our employees. There
is significant uncertainty about the duration and potential impact of the
COVID-19 pandemic. This means that our results could change at any time and the
contemplated impact of the COVID-19 pandemic on our business results and outlook
represents our estimate based on the information available as of the date of
this Quarterly Report on Form 10-Q.

Strategy



Horizon is a leading high-growth, innovation-driven, profitable global
biotechnology company. We are focused on the discovery, development and
commercialization of medicines that address critical needs for people impacted
by rare, autoimmune and severe inflammatory diseases. Our three strategic goals
are to: (i) maximize the value of our on-market rare disease medicines through
commercial execution and clinical investment; (ii) expand our research and
development, or R&D, pipeline through significant internal investment and
external business development; and (iii) build a global presence in targeted
international markets. Our vision is to build healthier communities, urgently
and responsibly, supported by our philosophy to make a meaningful difference for
patients and communities in need. We believe this generates value for our
multiple stakeholders, including our shareholders.

Our commercialization strategy for our on-market rare disease medicines,
including our key growth drivers TEPEZZA, KRYSTEXXA and UPLIZNA, includes
initiatives to increase awareness of the conditions each medicine is designed to
treat, enhancing efforts to identify target patients and, for TEPEZZA and
KRYSTEXXA, to promote earlier treatment; driving awareness of the benefits of
the medicines, including, for TEPEZZA, in the treatment of chronic/low CAS TED,
and for UPLIZNA, increasing awareness of what differentiates our medicines from
other available therapies; optimizing timely access for patients to the
medicines; and maximizing the value of the medicines through investment in
clinical trials. Specifically, with respect to TEPEZZA, we are further expanding
our commercial team and continuing to invest in our direct-to-consumer marketing
activities, as well as refining our marketing and physician education strategies
to address challenges we recently identified in driving adoption by ocular
specialists and driving an urgency among ophthalmologists and endocrinologists
to diagnose and refer TED patients.

Our R&D strategy is to expand our pipeline of preclinical and clinical
development programs to drive sustainable growth, as well as maximizing the
benefit and value of our existing medicines through development programs. We are
(i) acquiring, licensing and developing medicines for indications that address
unmet needs in rare, autoimmune and severe inflammatory diseases, particularly
those in our therapeutic areas of focus; (ii) maximizing our pipeline candidates
through internal R&D; (iii) expanding our early-stage pipeline through
partnerships and collaborations; and (iv) continuing to build out our research
capabilities to generate discovery-stage candidates internally. Our R&D pipeline
includes more than 20 programs, and we have initiated enrollment in three
clinical trials since the start of the year.

The aim of our global expansion strategy is to build a global presence in
targeted international markets to support the (i) planned launch of UPLIZNA in
certain European markets this year following the European Commission, or EC,
issuing a legally binding decision based on the favorable recommendation of the
Committee for Medicinal Products for Human Use, or CHMP, of the European
Medicines Agency, or EMA, to grant a Centralised Marketing Authorization, or
CMA, for UPLIZNA for the treatment of adult patients with neuromyelitis optica
spectrum disorder, or NMOSD, in the European Union, or EU, in April 2022; (ii)
potential approvals and commercial launches of UPLIZNA in other markets,
including Brazil, in the coming years; and (iii) potential approvals and
commercial launches of TEPEZZA in Japan, Brazil and other international markets
over the next several years. We plan to use a combination of direct marketing
and partnerships for our global expansion efforts and are establishing the
infrastructure needed to support these activities.

months ended June 30, 2021. The increase in net sales during the three months
ended June 30, 2022 was primarily due to an increase in net sales in our orphan
segment of $94.8 million, partially offset by a decrease in net sales in our
inflammation segment of $50.9 million when compared to the three months ended
June 30, 2021. Growth in our orphan segment was primarily due to an increase in
KRYSTEXXA net sales of $37.5 million, an increase in TEPEZZA net sales of $26.6
million and an increase in UPLIZNA net sales of $24.1 million.

Orphan Segment

TEPEZZA. Net sales increased $26.6 million, or 6%, to $479.8 million during the
three months ended June 30, 2022, from $453.2 million during the three months
ended June 30, 2021. Net sales increased by approximately $13.5 million due to
volume growth and $13.1 million due to higher net pricing. Net sales growth for
TEPEZZA was negatively impacted by the omicron variant of COVID-19 as described
above. We have recently begun executing on several opportunities to accelerate
growth, including significantly expanding the size of our TEPEZZA sales force to
allow our representatives more time with core TEPEZZA prescribers while
educating other key physicians about TED and TEPEZZA, and evolving our
commercial focus to improve the effectiveness of the team. We also continue to
invest significantly in direct-to-consumer advertising based on the returns we
have seen to date. However, it will take some time for these strategies to
contribute to TEPEZZA net sales growth.

KRYSTEXXA. Net sales increased $37.4 million, or 29%, to $167.8 million during
the three months ended June 30, 2022, from $130.3 million during the three
months ended June 30, 2021. Net sales increased by approximately $30.5 million
due to volume growth and $6.9 million due to higher net pricing.

RAVICTI. Net sales increased $7.3 million, or 11%, to $75.7 million during the
three months ended June 30, 2022, from $68.4 million during the three months
ended June 30, 2021. Net sales increased by approximately $4.4 million due to
volume growth and $2.9 million due to higher net pricing.

UPLIZNA. Net sales increased $24.1 million, or 167%, to $38.6 million during the
three months ended June 30, 2022, from $14.5 million during the three months
ended June 30, 2021. Net sales in the United States increased by $15.5 million,
which was composed of an increase of $13.3 million due to higher sales volume
and $2.2 million due to higher net pricing. The remaining $8.6 million increase
in net sales relates to revenue from our international partners recognized
during the three months ended June 30, 2022.

                                       35
--------------------------------------------------------------------------------

Inflammation Segment



Our interim goodwill impairment test in the second quarter of 2022 indicated an
impairment of the inflammation reporting unit. As a result, we recognized an
impairment charge of $56.2 million in June 2022 representing the full amount of
goodwill for the inflammation reporting unit. Refer to Note 8, Goodwill and
intangible assets, of the Notes to Condensed Consolidated Financial Statements,
included in Item 1 of this Quarterly Report on Form 10-Q, for further details.

PENNSAID 2%. Net sales decreased $25.3 million, or 52%, to $23.6 million during
the three months ended June 30, 2022, from $48.9 million during the three months
ended June 30, 2021. Net sales decreased by approximately $20.0 million
resulting from lower net pricing and by approximately $5.4 million due to lower
sales volume.

In May 2022, Apotex Corp. and its affiliate, Apotex Inc., or collectively
Apotex, initiated an at-risk launch of a generic version of PENNSAID 2% in the
United States. We subsequently initiated patent infringement litigation against
Apotex and Apotex agreed to a voluntary injunction against further sales of the
generic product pending the outcome of a motion for summary judgment. The
injunction prevents further sales by Apotex but does not prevent wholesalers
from continuing to resell the initial generic product inventory Apotex sold to
them prior to the injunction. The generic competition created pressure on our
PENNSAID 2% sales, resulting in increased utilization of co-pay and other
patient assistance programs for PENNSAID 2%, which negatively impacted net
pricing. We expect our net sales for PENNSAID 2% to continue declining in future
periods primarily due to generic competition and the planned wind down of our
inflammation segment, as described below.

RAYOS. Net sales decreased $2.3 million, or 17%, to $11.1 million during the
three months ended June 30, 2022, from $13.4 million during the three months
ended June 30, 2021. Net sales decreased by approximately $3.4 million due to
lower net pricing, partially offset by an increase of $1.1 million due to higher
sales volume.

We have an exclusive license to U.S. patents and patent applications from
Vectura Group plc covering RAYOS. Under our settlement agreement with Teva
Pharmaceuticals Industries Limited (formerly known as Actavis Laboratories FL,
Inc., which itself was formerly known as Watson Laboratories, Inc. - Florida),
or Teva, Teva may enter the market on December 23, 2022, or earlier under
certain circumstances. As a result, we expect our net sales for RAYOS to decline
in future periods.

VIMOVO. Net sales decreased $1.3 million, or 81%, to $0.3 million during the
three months ended June 30, 2022, from $1.6 million during the three months
ended June 30, 2021. Net sales decreased by approximately $0.9 million due to
lower sales volume as a result of generic competition and $0.4 million due to
lower net pricing.

DUEXIS. Net sales decreased $22.0 million, or 100%, to $0.1 million during the
three months ended June 30, 2022, from $22.1 million during the three months
ended June 30, 2021. Net sales decreased by approximately $19.8 million
resulting from lower sales volume, primarily due to the impact of generic
competition, and by approximately $2.2 million due to lower net pricing.

Due to the impact of the at-risk launch of generic PENNSAID 2%, we are in the
process of redeploying a portion of our inflammation commercial team to support
our TEPEZZA expansion. We plan to wind down activities, including active
promotion efforts and associated HorizonCares support, for our inflammation
segment by the end of the year. As a result, we expect that sales volumes for
PENNSAID 2% and RAYOS will decline significantly for the remainder of 2022.

The table below reconciles our gross to net sales for the three months ended June 30, 2022 and 2021 (in millions, except percentages):

During the three months ended June 30, 2022, co-pay and other patient assistance
costs, as a percentage of gross sales, decreased to 8.0% from 15.2% during the
three months ended June 30, 2021, primarily due to a decreased proportion of
inflammation segment medicines sold. Due to the impacts described above with
respect to the inflammation segment, we expect co-pay and other patient
assistance costs to continue to decrease as a percentage of total gross sales.

                                       36
--------------------------------------------------------------------------------
Cost of Goods Sold. Cost of goods sold increased $29.2 million to $230.2 million
during the three months ended June 30, 2022, from $201.0 million during the
three months ended June 30, 2021. The increase in cost of goods sold during the
three months ended June 30, 2022 compared to the three months ended June 30,
2021, was primarily due to an increase in royalty and earnout expense and an
increase in inventory step-up expense. Royalty and earnout expense increased by
$15.6 million primarily due to royalties payable on net sales of TEPEZZA, which
increased in the three months ended June 30, 2022 compared to the three months
ended June 30, 2021 due to higher net sales. Inventory step-up expense increased
by $10.3 million related to UPLIZNA based on the acquired units of inventory
sold during the three months ended June 30, 2022 compared to the three months
ended June 30, 2021. In addition, we recorded an $8.8 million inventory reserve
due to the impact of generic competition on PENNSAID 2% sales. As a percentage
of net sales, cost of goods sold (excluding intangible amortization expense of
$90.4 million during the three months ended June 30, 2022 and $88.3 million
during the three months ended June 30, 2021) was 16% during the three months
ended June 30, 2022, compared to 14% during the three months ended June 30,
2021. The increase in cost of goods sold as a percentage of net sales was
primarily due to a change in the mix of medicines sold and increases in
inventory step-up expense related to UPLIZNA as noted above.

Research and Development Expenses. R&D expenses decreased $36.6 million to
$103.2 million during the three months ended June 30, 2022, from $139.8 million
during the three months ended June 30, 2021. The decrease was primarily
attributable to recognition of a $40.0 million upfront payment in relation to
the agreement with Arrowhead Pharmaceuticals, Inc., or Arrowhead, during the
three months ended June 30, 2021. This was partially offset by a $11.3 million
increase in clinical trial costs reflecting increased activity in our R&D
pipeline during the three months ended June 30, 2022 compared to three months
ended June 30, 2021.

We expect our R&D expenses to continue increasing significantly in future periods as a result of our on-going and planned clinical trials for our pipeline including new medicine candidates and development programs acquired in 2021.



Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $43.0 million to $398.2 million during the
three months ended June 30, 2022, from $355.2 million during the three months
ended June 30, 2021. The increase was primarily attributable to costs associated
with the commercialization of our medicines and global expansion initiatives,
including an increase of $36.1 million in marketing program costs.

We expect our selling, general and administrative expenses to increase in future
periods primarily due to continued support for our U.S. commercial and global
expansion activities.

Impairment of goodwill. During the three months ended June 30, 2022, we recorded
an impairment charge of $56.2 million in relation to our inflammation reporting
unit. Refer to Note 8, Goodwill, of the Notes to the Condensed Consolidated
Financial Statements, included in Item 1 of this Quarterly Report on Form 10-Q
for further details.

Gain on sale of asset. During the three months ended June 30, 2021, gain on sale
of asset represents a $2.0 million contingent consideration payment related to
the sale of MIGERGOT in 2019. The contingent consideration was earned during the
second quarter of 2021 and it was received in July 2021.

Expense (benefit) for Income Taxes. During the three months ended June 30, 2022,
we recorded an expense for income taxes of $3.8 million compared to a benefit
for income taxes of $42.5 million during the three months ended June 30, 2021.
The expense for income taxes recorded during the three months ended June 30,
2022, resulted primarily from the mix of pre-tax income and losses incurred in
various tax jurisdictions.

Net Sales. The increase in orphan segment net sales during the three months ended June 30, 2022 is described in the Consolidated Results section above.



Segment operating income. Orphan segment operating income decreased $6.1 million
to $315.1 million during the three months ended June 30, 2022, from $321.2
million during the three months ended June 30, 2021. The decrease was primarily
attributable to an increase in selling, general and administrative expenses of
$76.0 million, an increase in royalty expenses of $16.0 million and an increase
in R&D expenses of $14.4 million, partially offset by an increase in net sales
of $94.8 million as described above.

decreased $53.3 million to a $6.5 million operating loss during the three months
ended June 30, 2022, from $46.8 million in operating income during the three
months ended June 30, 2021. The decrease was primarily attributable to a
decrease in net sales of $50.9 million as described above.

Net sales. Net sales increased $586.7 million, or 50%, to $1,761.6 million
during the six months ended June 30, 2022, from $1,174.9 million during the six
months ended June 30, 2021. The increase in net sales during the six months
ended June 30, 2022 was primarily due to an increase in net sales in our orphan
segment of $671.6 million. Growth was primarily due to an increase in TEPEZZA
net sales of $526.0 million, an increase in KRYSTEXXA net sales of $71.4 million
and an increase in UPLIZNA net sales of $52.7 million, partially offset by a
decrease in net sales in our inflammation segment of $84.9 million when compared
to the six months ended June 30, 2021 which was primarily driven by a decrease
in net sales of DUEXIS and PENNSAID 2% due to the impact of generic competition.

Orphan Segment



TEPEZZA. Net sales increased $526.0 million, or 116%, to $981.3 million during
the six months ended June 30, 2022, from $455.3 million during the six months
ended June 30, 2021. Net sales increased by approximately $506.9 million due to
volume growth and $19.1 million due to higher net pricing. Net sales growth for
TEPEZZA was negatively impacted by the omicron variant of COVID-19 and
additional commercial challenges we recently identified, as described above. We
are implementing strategies to further accelerate TEPEZZA net sales growth
however, it will take some time for these strategies to contribute to TEPEZZA
net sales growth.

KRYSTEXXA. Net sales increased $71.4 million, or 30%, to $308.4 million during
the six months ended June 30, 2022 from $237.0 million during the six months
ended June 30, 2021. Net sales increased by approximately $53.3 million due to
volume growth and $18.1 million due to higher net pricing.

RAVICTI. Net sales increased $12.7 million, or 9%, to $153.9 million during the
six months ended June 30, 2022, from $141.2 million during the six months ended
June 30, 2021. Net sales increased by approximately $10.5 million due to volume
growth and $2.2 million due to higher net pricing.

UPLIZNA. Net sales increased $52.7 million, or 323%, to $69.0 million during the
six months ended June 30, 2022, from $16.3 million during the six months ended
June 30, 2021. Net sales in the United States increased by $38.9 million, which
was composed of an increase of $35.9 million due to higher sales volume and $3.0
million due to higher net pricing. The remaining $13.8 million increase in net
sales relates to revenue and milestone payments from our international partners
recognized during the six months ended June 30, 2022.

Inflammation Segment



Our interim goodwill impairment test in the second quarter of 2022 indicated an
impairment of the inflammation reporting unit. As a result, we recognized an
impairment charge of $56.2 million in June 2022 representing the full amount of
goodwill for the inflammation reporting unit. Refer to Note 8, Goodwill and
intangible assets, of the Notes to Condensed Consolidated Financial Statements,
included in Item 1 of this Quarterly Report on Form 10-Q, for further details.

PENNSAID 2%. Net sales decreased $35.8 million, or 38%, to $58.9 million during
the six months ended June 30, 2022, from $94.7 million during the six months
ended June 30, 2021. Net sales decreased by approximately $27.8 million
resulting from lower net pricing and by approximately $8.0 million due to lower
sales volume.

In May 2022, Apotex initiated an at-risk launch of a generic version of PENNSAID
2% in the United States. We subsequently initiated patent infringement
litigation against Apotex and Apotex agreed to a voluntary injunction against
further sales of the generic product pending the outcome of a motion for summary
judgment. The injunction prevents further sales by Apotex but does not prevent
wholesalers from continuing to resell the initial generic product inventory
Apotex sold to them prior to the injunction. The generic competition created
pressure on our PENNSAID 2% sales, resulting in increased utilization of co-pay
and other patient assistance programs for PENNSAID 2%, which negatively impacted
net pricing. We expect our net sales for PENNSAID 2% to continue declining in
future periods primarily due to generic competition and the planned wind down of
our inflammation segment.

RAYOS. Net sales decreased $4.1 million, or 14%, to $24.6 million during the six
months ended June 30, 2022, from $28.7 million during the six months ended June
30, 2021. Net sales decreased by approximately $4.9 million due to lower net
pricing, partially offset by an increase of $0.8 million due to higher sales
volume.

We have an exclusive license to U.S. patents and patent applications from Vectura Group plc covering RAYOS. Under our settlement agreement with Teva, Teva may enter the market on December 23, 2022, or earlier under certain circumstances. As a result, we expect our net sales for RAYOS to decline in future periods.



VIMOVO Net sales decreased $4.7 million, or 80%, to $1.2 million during the six
months ended June 30, 2022, from $5.9 million during the six months ended June
30, 2021. Net sales decreased by approximately $3.7 million due to lower sales
volume as a result of generic competition and $1.0 million due to lower net
pricing.

DUEXIS. Net sales decreased $40.3 million, or 97%, to $1.2 million during the
six months ended June 30, 2022, from $41.5 million during the six months ended
June 30, 2021. Net sales decreased by approximately $36.5 million resulting from
lower sales volume, primarily due to the impact of generic competition, and by
approximately $3.8 million due to lower net pricing.

Due to the impact of the at-risk launch of generic PENNSAID 2%, we are in the
process of redeploying a portion of our inflammation commercial team to support
our TEPEZZA expansion. We plan to wind down activities, including active
promotion efforts and associated HorizonCares support, for our inflammation
segment by the end of the year. As a result, we expect that sales volumes for
PENNSAID 2% and RAYOS will decline significantly for the remainder of 2022.

During the six months ended June 30, 2022, co-pay and other patient assistance
costs, as a percentage of gross sales, decreased to 7.4% from 19.2% during the
six months ended June 30, 2021, primarily due to a decreased proportion of
inflammation segment medicines sold. Due to the impacts described above with
respect to the inflammation segment, we expect co-pay and other patient
assistance costs to continue to decrease as a percentage of total gross sales.

Cost of Goods Sold. Cost of goods sold increased $144.0 million to $445.3
million during the six months ended June 30, 2022, from $301.3 million during
the six months ended June 30, 2021. The increase in cost of goods sold was
primarily due to an increase in royalty and earnout expense, an increase in
inventory step-up expense and an increase in amortization expense. Royalty and
earnout expense increased by $71.1 million primarily due to royalties payable on
net sales of TEPEZZA, which increased during the first half of 2022 compared to
the first half of 2021 due to higher net sales. Inventory step-up expense
increased by $36.6 million related to UPLIZNA based on the acquired units of
inventory sold during the six months ended June 30, 2022 compared to the six
months ended June 30, 2021. Amortization expense increased $24.7 million
primarily due to the acquisition of the UPLIZNA developed technology intangible
asset in March 2021. In addition, we recorded an $8.8 million PENNSAID 2%
inventory reserve due to the impact of generic competition on PENNSAID 2% sales.
As a percentage of net sales, cost of goods sold (excluding amortization expense
of $179.2 million during the first half of 2022 and $154.5 million during first
half of 2021) was 15% during the six months ended June 30, 2022, compared to 12%
during the six months ended June 30, 2021. The increase in cost of goods sold as
a percentage of net sales was primarily due to a change in the mix of medicines
sold and increases in inventory step-up expense related to UPLIZNA as noted
above.

Research and Development Expenses. R&D expenses increased $8.9 million to $206.4
million during the six months ended June 30, 2022, from $197.5 million during
the six months ended June 30, 2021. The increase was primarily attributable to a
$27.7 million increase in clinical trial costs reflecting increased activity in
our R&D pipeline as well as the addition of our new medicine candidates and
development programs following the acquisition of Viela in March 2021, and an
increase of $13.0 million in consultant costs and $8.3 million in
employee-related costs. This is partially offset by $40.0 million of upfront
payments recognized during the six months ended June 30, 2021, in relation to
the agreement with Arrowhead.

We expect our R&D expenses to continue increasing significantly in future periods as a result of our on-going and planned clinical trials for our pipeline including new medicine candidates and development programs acquired in 2021.



Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $83.8 million to $771.0 million during the six
months ended June 30, 2022, from $687.2 million during the six months ended June
30, 2021. The increase was primarily attributable to costs associated with the
commercialization of our medicines and global expansion initiatives. These
include an increase of $87.3 million in marketing program costs and an increase
of $10.1 million in employee-related costs, partially offset by a decrease of
$28.6 million in transaction costs which were incurred during the six months
ended June 30, 2021 relating to the Viela acquisition.

We expect our selling, general and administrative expenses to increase in future
periods primarily due to continued support for our U.S. commercial and global
expansion activities.

Impairment of goodwill. During the six months ended June 30, 2022, we recorded
an impairment charge of $56.2 million in relation to our inflammation reporting
unit. Refer to Note 8, Goodwill, of the Notes to the Condensed Consolidated
Financial Statements, included in Item 1 of this Quarterly Report on Form 10-Q
for further details.

Impairment of long-lived assets. During the six months ended June 30, 2021, we
recorded an impairment charge of $12.4 million as a result of vacating the Lake
Forest office. Refer to Note 15, Lease Obligations, of the Notes to Condensed
Consolidated Financial Statements, included in Item 1 of this Quarterly Report
on Form 10-Q for further details.

Gain on sale of asset. During the six months ended June 30, 2021, gain on sale
of asset represents a $2.0 million contingent consideration payment related to
the sale of MIGERGOT in 2019. The contingent consideration was earned during the
second quarter of 2021 and it was received in July 2021.


Interest Expense, Net. Interest expense, net, increased $6.6 million to $42.6
million during the six months ended June 30, 2022, from $36.0 million during the
six months ended June 30, 2021. The increase was primarily due to an increase in
interest expense of $9.4 million, primarily related to an additional $1.6
billion aggregate principal amount of term loans borrowed pursuant to an
amendment to our Credit Agreement, the proceeds of which, in addition to a
portion of our existing cash on hand, was used to pay the consideration for the
Viela acquisition and increases in interest rates on the portion of our variable
interest debt, partially offset by an increase in interest income of $3.0
million. Refer to Note 13, Debt Agreements, of the Notes to Condensed
Consolidated Financial Statements, included in Item 1 of this Quarterly Report
on Form 10-Q for further details.

Benefit for Income Taxes. During the six months ended June 30, 2022, we recorded
a benefit for income taxes of $27.7 million compared to a benefit for income
taxes of $90.2 million during the six months ended June 30, 2021. The benefit
for income taxes recorded during the six months ended June 30, 2022, resulted
primarily from tax benefits recognized on share-based compensation, partially
offset by the mix of pre-tax income and losses incurred in various tax
jurisdictions.

Segment operating income. Inflammation segment operating income decreased $80.6
million to $8.8 million during the six months ended June 30, 2022, from $89.4
million during the six months ended June 30, 2021. The decrease was primarily
attributable to a decrease in net sales of $84.9 million as described above,
partially offset by a decrease in selling, general and administrative expenses
of $7.9 million.

NON-GAAP FINANCIAL MEASURES



We provide certain non-GAAP financial measures, including EBITDA, or earnings
before interest, taxes, depreciation and amortization, adjusted EBITDA, non-GAAP
net income and non-GAAP earnings per share. These non-GAAP financial measures
are intended to provide additional information on our performance, operations
and profitability. Adjustments to our GAAP figures as well as EBITDA exclude
acquisition/divestiture-related costs, manufacturing plant start-up costs and
restructuring and realignment costs, as well as non-cash items such as
share-based compensation, inventory step-up expense, depreciation and
amortization, non-cash interest expense, long-lived assets impairment charges,
loss on equity security investments 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. We maintain an established non-GAAP cost policy that guides the
determination of what costs will be excluded in non-GAAP measures. We believe
that these non-GAAP financial measures, when considered together with the GAAP
figures, can enhance an overall understanding of our financial and operating
performance. The non-GAAP financial measures are included with the intent of
providing investors with a more complete understanding of our historical
financial results and trends and to facilitate comparisons between periods. In
addition, these non-GAAP financial measures are among the indicators our
management uses for planning and forecasting purposes and measuring our
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 us may be
calculated differently from, and therefore may not be comparable to, non-GAAP
financial measures used by other companies.

Beginning in the fourth quarter of 2021, following consultation with the staff
of the Division of Corporation Finance of the U.S. Securities and Exchange
Commission, we no longer exclude upfront and milestone payments related to
license and collaboration agreements from our non-GAAP financial measures and
its line-item components. For purposes of comparability, non-GAAP financial
measures for the three and six months ended June 30, 2021 have been updated to
reflect this change. The upfront and milestone payments related to license and
collaboration agreements continue to be excluded from our segment operating
income (loss) and from certain measures contained in our credit agreement that
are relevant to, among other things, the calculation of the interest rate.

Reconciliations of reported GAAP net income to EBITDA, adjusted EBITDA and non-GAAP net income, and the related per share amounts, were as follows (in thousands, except share and per share amounts):

(1) Represents depreciation expense related to our property, plant, equipment,


       software and leasehold improvements.



   (2) Intangible amortization expenses are primarily associated with our

developed technology related to TEPEZZA, KRYSTEXXA, RAVICTI, PROCYSBI,


       UPLIZNA, ACTIMMUNE, BUPHENYL and RAYOS.


(3) During the three and six months ended June 30, 2022, we recognized in cost

of goods sold $17.4 million and $44.6 million, respectively, for inventory


       step-up expense related to UPLIZNA inventory revalued in connection with
       the Viela acquisition. We recorded $7.1 million and $8.0 million,
       respectively, of UPLIZNA inventory step-up expense in cost of goods sold
       during the three and six months ended June 30, 2021. Refer to Note 5,

Inventories, of the Notes to Condensed Consolidated Financial Statements,


       included in Item 1 of this Quarterly Report on Form 10-Q for further
       details.



   (4) Our interim goodwill impairment test in the second quarter of 2022
       indicated an impairment which represented the difference between the

estimated fair value of the inflammation reporting unit and its carrying

value. As a result, we recognized an impairment charge of $56.2 million in

June 2022 representing the full amount of goodwill for the inflammation

reporting unit. Refer to Note 8, Goodwill and intangible assets, of the

Notes to Condensed Consolidated Financial Statements, included in Item 1 of


       this Quarterly Report on Form 10-Q, for further details.


(5) Represents share-based compensation expense associated with our stock

option, restricted stock unit and performance stock unit grants to our

employees and non-employee directors, and our employee share purchase plan.

(6) During the three and six months ended June 30, 2022, we recorded $1.6

million and $2.4 million, respectively, of manufacturing plant start-up


       costs related to our biologic drug product manufacturing facility in
       Waterford.


                                       45

--------------------------------------------------------------------------------

(7) Represents rent and maintenance charges as a result of vacating the leased

Lake Forest office in the first quarter of 2021.



   (8) Primarily represents transaction and integration costs, including,

advisory, legal, consulting and certain employee-related costs, incurred in

connection with our acquisitions and divestitures. Costs recovered from

subleases of acquired facilities and reimbursed expenses incurred under

transition arrangements for divestitures are also reflected in this line


       item.


(9) We held investments in equity securities with readily determinable fair

values of $8.1 million as of June 30, 2022, which are included in other

long-term assets in the condensed consolidated balance sheet. For the three

and six months ended June 30, 2022, we recognized a net unrealized loss of

$0.4 million and $5.1 million, respectively, due to the change in fair
       value of these securities.


(10) During the six months ended June 30, 2021, we recorded a right-of-use


        asset impairment charge of $12.4 million as a result of vacating the
        leased Lake Forest office.

        associated with our debt.


(13) Income tax adjustments on pre-tax non-GAAP adjustments represent the

estimated income tax impact of each pre-tax non-GAAP adjustment based on

the statutory income tax rate of the applicable jurisdictions for each


        non-GAAP adjustment.


(14) During the three months ended June 30, 2021, we recognized a U.S. federal


        and state tax liability on U.S. taxable income generated from an
        intercompany transfer and license of intellectual property from a U.S.
        subsidiary to an Irish subsidiary which was partially offset by the

recognition of a deferred tax asset in the Irish subsidiary, resulting in

a non-GAAP tax adjustment of $34.0 million. We also recognized $3.1

million of tax benefit relating to the release of a valuation allowance

which was originally recognized on state net operating losses acquired

through the acquisition of Viela. These state net operating losses are now


        usable, resulting in a non-GAAP tax adjustment of $3.1 million.


(15) As discussed above, following consultation with the staff of the Division

of Corporation Finance of the U.S. Securities and Exchange Commission, we


        no longer exclude upfront and milestone payments related to license and
        collaboration agreements from our non-GAAP financial measures and its
        line-item components. Adjusted EBITDA and non-GAAP net income for the

three and six months ended June 30, 2021, includes $46.5 million and $49.5


        million, respectively, of upfront and milestone payments related to
        license and collaboration agreements. These amounts continue to be
        excluded from our segment operating income (loss) and from certain
        measures contained in our credit agreement that are relevant to, among
        other things, the calculation of the interest rate.

LIQUIDITY, FINANCIAL POSITION AND CAPITAL RESOURCES



As of June 30, 2022, we had retained earnings of $583.8 million. We expect that
our sales and marketing expenses will continue to increase as a result of the
commercialization of our medicines and global expansion initiatives, but we
believe these cost increases will be more than offset by higher net sales and
gross profits in future periods. Additionally, we expect that our R&D costs will
continue to increase as we acquire or develop more development-stage medicine
candidates and advance our candidates through the clinical development and
regulatory approval processes. In particular, we expect to incur substantial
costs in connection with advancing our pipeline of medicine candidates and
development programs in on-going and planned clinical trials.

We are in the process of expanding our production capacity to meet anticipated
future demand for TEPEZZA, primarily for 2023 and beyond. As of June 30, 2022,
we had total purchase commitments, including the minimum annual order quantities
and binding firm orders, with AGC Biologics A/S (formerly known as CMC Biologics
A/S) for TEPEZZA drug substance of €94.9 million ($99.3 million converted at a
Euro-to-Dollar exchange rate as of June 30, 2022 of 1.0462), to be delivered
through June 2024.

We also expect to incur additional costs and to enter into additional purchase
commitments in connection with our efforts to expand TEPEZZA production capacity
in order to meet anticipated increases in demand.

Under our license agreement with F. Hoffmann-La Roche Ltd and Hoffmann-La Roche Inc., or together referred to as Roche, our remaining obligation to Roche relating to the attainment of various TEPEZZA development and regulatory milestones is CHF43.0 million ($45.0 million when converted using a CHF-to-Dollar exchange rate at June 30, 2022 of 1.0467).



In July 2021, we completed the purchase of a biologic drug product manufacturing
facility from EirGen for $67.9 million. Refer to Note 4, Acquisitions,
Divestitures and other Arrangements, of the Notes to Condensed Consolidated
Financial Statements, included in Item 1 of this Quarterly Report on Form 10-Q
for further details. We expect to incur approximately $40.0 million in capital
expenditures during the second half of 2022 in order to complete the drug
product facility.

We are committed to invest as a strategic limited partner in four venture
capital funds: Forbion Growth Opportunities Fund I C.V., Forbion Capital Fund V
C.V., Aisling Capital V, L.P. and RiverVest Venture Fund V, L.P. As of June 30,
2022, the total carrying amount of our investments in these funds was $22.4
million, which is included in other long-term assets in the condensed
consolidated balance sheet, and our total future commitments to these funds are
$38.2 million.

We have financed our operations to date through equity financings, debt
financings and the issuance of convertible notes, along with cash flows from
operations during the last several years. As of June 30, 2022, we had $1.9
billion in cash and cash equivalents and total debt with a book value of $2.6
billion and face value of $2.6 billion. We believe our existing cash and cash
equivalents and our expected cash flows from our operations will be sufficient
to fund our business needs for at least the next 12 months from the issuance of
the financial statements in this Quarterly Report on Form 10-Q. We do not have
any financial covenants or non-financial covenants that we expect to be affected
by the economic disruptions and negative effects of the COVID-19 pandemic.

We have a significant amount of debt outstanding on a consolidated basis. For a
description of our debt agreements, refer to Note 13, Debt Agreements, of the
Notes to Condensed Consolidated Financial Statements, included in Item 1 of this
Quarterly Report on Form 10-Q. This substantial level of debt could have
important consequences to our business, including, but not limited to: making it
more difficult for us to satisfy our obligations; requiring a substantial
portion of our cash flows from operations to be dedicated to the payment of
principal and interest on our indebtedness, therefore reducing our ability to
use our cash flows to fund acquisitions, capital expenditures, R&D and future
business opportunities; limiting our ability to obtain additional financing,
including borrowing additional funds; increasing our vulnerability to, and
reducing our flexibility to respond to, general adverse economic and industry
conditions, including rising interest rates; limiting our flexibility in
planning for, or reacting to, changes in our business and the industry in which
we operate; and placing us at a disadvantage as compared to our competitors, to
the extent that they are not as highly leveraged. We may not be able to generate
sufficient cash to service all of our indebtedness and may be forced to take
other actions to satisfy our obligations under our indebtedness.

In addition, the indenture governing our 5.5% Senior Notes due 2027 and our Credit Agreement impose various covenants that limit our ability and/or our restricted subsidiaries' ability to, among other things, pay dividends or distributions, repurchase equity, prepay junior debt and make certain investments, incur additional debt and issue certain preferred stock, incur liens on assets, engage in certain asset sales or merger transactions, enter into transactions with affiliates, designate subsidiaries as unrestricted subsidiaries; and allow to exist certain restrictions on the ability of restricted subsidiaries to pay dividends or make other payments to us.



On April 25, 2022, we entered into two interest rate swap agreements with
notional amounts totaling $800.0 million, effective June 24, 2022, to hedge or
otherwise protect against interest rate fluctuations on a portion of our
variable rate debt. The agreements effectively fix LIBOR at approximately 2.8%
through December 24, 2026. These agreements were designated as cash flow hedges
of the variability of future cash flows subject to the variable monthly interest
rates on $800.0 million of our 2028 Term Loans and the 2026 Term Loans. Refer to
Note 14, Derivative Instruments and Hedging Activities, of the Notes to
Condensed Consolidated Financial Statements, included in Item 1 of this
Quarterly Report on Form 10-Q for further details.

                                       47
--------------------------------------------------------------------------------
During the six months ended June 30, 2022, we issued an aggregate of 2,955,857
of our ordinary shares in connection with stock option exercises, the vesting of
restricted stock units and performance stock units, and employee share purchase
plan purchases. We received a total of $35.9 million in net proceeds in
connection with such issuances. During the six months ended June 30, 2022, we
made payments of $120.5 million for employee withholding taxes relating to
vesting of share-based awards.

Since our inception, we have not engaged in any off-balance sheet arrangements,
including the use of structured finance, special purpose entities or variable
interest entities, other than the indemnification agreements discussed in Note
16, Commitments and Contingencies, of the Notes to Condensed Consolidated
Financial Statements, included in Item 1 of this Quarterly Report on Form 10-Q.

administrative expenses and payments related to R&D expenses.

During the six months ended June 30, 2021, net cash provided by operating

administrative expenses, including transaction costs related to the Viela
acquisition, and payments related to R&D expenses.

Investing Cash Flows



During the six months ended June 30, 2022, net cash used in investing activities
of $52.9 million was primarily attributable to an upfront payment of $25.0
million paid to Alpine Immune Sciences, Inc., or Alpine, in the first quarter of
2022 relating to an exclusive license agreement entered into in December 2021
and payments related to purchases of property, plant and equipment of $24.4
million. Refer to Note 4, Acquisitions, Divestitures and other Arrangements, of
the Notes to Condensed Consolidated Financial Statements, included in Item 1 of
this Quarterly Report on Form 10-Q, for further details on the Alpine license
agreement.

During the six months ended June 30, 2021, net cash used in investing activities
of $2,815.2 million was primarily attributable to payments for acquisitions, net
of $2,775.3 million which was primarily attributable to $2.6 billion paid in
relation to the Viela acquisition, net of acquired cash. In addition, we made a
milestone payment of CHF50.0 million ($56.1 million when converted using a
CHF-to-Dollar exchange rate at the date of payment of 1.1228) under our license
agreement with Roche, during the first quarter of 2021 and a milestone payment
of $67.0 million to the former River Vision stockholders in April 2021.

Financing Cash Flows



During the six months ended June 30, 2022, net cash used in financing activities
of $92.6 million was primarily attributable to $120.5 million in payments of
employee withholding taxes relating to share-based awards, partially offset by
$35.9 million in proceeds from the issuance of ordinary shares in connection
with stock option exercises and employee share purchase plan purchases.

During the six months ended June 30, 2021, net cash provided by financing
activities of $1,468.7 million was primarily attributable to an additional $1.6
billion aggregate principal amount of term loans borrowed pursuant to an
amendment to our Credit Agreement, the proceeds of which, in addition to a
portion of our existing cash on hand, was used to pay the consideration for the
Viela acquisition, partially offset by the payment of $141.6 million of employee
withholding taxes relating to share-based awards.

--------------------------------------------------------------------------------

Financial Condition as of June 30, 2022 Compared to December 31, 2021



Prepaid expenses and other current assets. Prepaid expenses and other current
assets increased $71.7 million, from $357.1 million as of December 31, 2021 to
$428.8 million as of June 30, 2022. The increase was primarily due to an
increase of $55.4 million in deferred charges for taxes on intercompany profits
and an increase of $28.3 million in upfront payments for inventory, partially
offset by a decrease in prepaid income taxes and an income tax receivable of
$13.1 million.

Developed technology and other intangible assets, net. Developed technology and
other intangible assets, net, decreased $109.5 million, from $2,960.1 million as
of December 31, 2021 to $2,850.6 million as of June 30, 2022, primarily related
to a decrease of $180.6 million related to amortization of developed technology
during the six months ended June 30, 2022. This was partially offset by $70.0
million of in-process research and development, or IPR&D, reclassified to
developed technology in the second quarter of 2022 due to the EC issuing a
legally binding decision to grant a CMA for UPLIZNA for the treatment of adult
patients with NMOSD in the EU in April 2022. Refer to Note 8, Goodwill and
intangible assets, of the Notes to Condensed Consolidated Financial Statements,
included in Item 1 of this Quarterly Report on Form 10-Q, for further details.

In-process research and development. IPR&D decreased $70.0 million, from $880.0
million as of December 31, 2021 to $810.0 million as of June 30, 2022, primarily
related to the reclassification of $70.0 million of IPR&D relating to UPLIZNA to
developed technology in the second quarter of 2022. Refer to Note 8, Goodwill
and intangible assets, of the Notes to Condensed Consolidated Financial
Statements, included in Item 1 of this Quarterly Report on Form 10-Q, for
further details.

Goodwill. Goodwill decreased $56.2 million, from $1,066.7 million as of December
31, 2021 to $1,010.5 million as of June 30, 2022. Our interim goodwill
impairment test in the second quarter of 2022 indicated an impairment which
represented the difference between the estimated fair value of the inflammation
reporting unit and its carrying value. As a result, we recognized an impairment
charge of $56.2 million in June 2022 representing the full amount of goodwill
for the inflammation reporting unit. Refer to Note 8, Goodwill and intangible
assets, of the Notes to Condensed Consolidated Financial Statements, included in
Item 1 of this Quarterly Report on Form 10-Q, for further details.

Accrued expenses and other current liabilities. Accrued expenses and other
current liabilities decreased $104.0 million, from $523.0 million as of December
31, 2021 to $419.0 million as of June 30, 2022. This was primarily due to a
decrease in accrued payroll-related expenses of $65.9 million, a decrease in
accrued upfront and milestone payments of $35.1 million, and a decrease in
accrued royalties of $21.4 million, partially offset by an increase in accrued
advertising and marketing expenses of $14.6 million.

Contractual Obligations

As of June 30, 2022, there were no material changes to our contractual obligations as previously disclosed in Part II, Item 7 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

CRITICAL ACCOUNTING POLICIES



The preparation of financial statements in accordance with U.S. GAAP principles
requires the use of estimates and assumptions that affect the reported amounts
of assets and liabilities and the reported amounts of revenue and expenses.
Certain of these policies are considered critical as these most significantly
impact a company's financial condition and results of operations and require the
most difficult, subjective or complex judgments, often as a result of the need
to make estimates about the effect of matters that are inherently uncertain.
Actual results may vary from these estimates.

During the six months ended June 30, 2022, there have been no significant
changes in our application of our critical accounting policies. A summary of our
critical accounting policies is included in Item 7 to our Annual Report on Form
10-K for the year ended December 31, 2021.
