Overview


We are a commercial-stage biopharmaceutical company focused on the discovery,
development and commercialization of novel therapeutic compounds to treat
diseases with high unmet needs through the inhibition of the complement system,
which is an integral component of the immune system, at the level of C3, the
central protein in the complement cascade. We believe that this approach can
result in broad inhibition of the principal pathways of the complement system
and has the potential to effectively control a broad array of
complement-dependent autoimmune and inflammatory diseases.

In May 2021, the U.S. Food and Drug Administration, or the FDA, approved
EMPAVELI® (pegcetacoplan), the first targeted C3 therapy and our first approved
product, for the treatment of paroxysmal nocturnal hemoglobinuria, or PNH.
EMPAVELI is approved for use in adults with PNH and can be used by patients who
are either treatment-naïve or who are switching from C5 inhibitors eculizumab or
ravulizumab. We believe that EMPAVELI has the potential to elevate the standard
of care in PNH and are seeking to establish EMPAVELI as the preferred first-line
treatment for patients. In the United States, there are approximately 1,500
patients with PNH currently being treated with C5 inhibitors and another 150
patients who are expected to be newly diagnosed each year. Since our launch of
EMPAVELI in May 2021 through June 30, 2022, we generated $42.9 million in net
product revenue from sales. For the three and six months ended June 30, 2022, we
generated $15.7 million and $27.8 million, respectively, in net product revenue
from sales of EMPAVELI.

In December 2021, the European Commission, or the EC, approved Aspaveli®
(pegcetacoplan) for the treatment of adults with PNH who are anemic after
treatment with a C5 inhibitor for at least three months. In January 2022,
systemic pegcetacoplan was also approved for the treatment of PNH in Saudi
Arabia and Australia, and in March 2022, systemic pegcetacoplan was approved for
the treatment of PNH in the United Kingdom. Systemic pegcetacoplan is currently
marketed under the trade name EMPAVELI™ in the United States, Saudi Arabia and
Australia and Aspaveli in the European Union and United Kingdom. Under our
collaboration and license agreement with Swedish Orphan Biovitrum AB (Publ), or
Sobi, Sobi has global co-development and exclusive ex-U.S. commercialization
rights for systemic pegcetacoplan and initiated the commercial launch of
EMPAVELI/Aspaveli in jurisdictions outside of the United States during the first
quarter of 2022. We have commercialization rights for systemic pegcetacoplan in
the United States.

We also are leveraging our expertise in targeting C3 to advance intravitreal
pegcetacoplan as the first potential treatment for geographic atrophy, or GA,
secondary to age-related macular degeneration, or AMD. Intravitreal
pegcetacoplan has the potential to be a breakthrough for patients with GA, a
disease that affects approximately one million people in the U.S. and five
million people worldwide. Based on the results of our Phase 3 (DERBY and OAKS)
and Phase 2 (FILLY) clinical trials of intravitreal pegcetacoplan, we submitted
a new drug application, or NDA, to the FDA in June 2022 with a request for
six-month priority review. In July 2022, the FDA accepted the NDA and granted
priority review with a Prescription Drug User Fee Act (PDUFA) target date of
November 26, 2022. The FDA stated that it is not planning to hold an advisory
committee meeting to discuss the NDA. We also plan to submit a

                                       22

market authorization application, or MAA, to the European Medicines Agency, or the EMA, in the second half of 2022. We have exclusive, worldwide commercialization rights for intravitreal pegcetacoplan.


We believe that inhibition of the complement system by targeting C3 may enable a
broad range of therapeutic approaches, and that pegcetacoplan has the potential
to address the limitations of existing treatment options or provide a treatment
option in indications where there currently are none. Under our collaboration
with Sobi, we are co-developing systemic pegcetacoplan for cold agglutinin
disease, or CAD, and hematopoietic stem cell transplantation-associated
thrombotic microangiopathy, or HSCT-TMA, in hematology; C3 glomerulopathy, or
C3G, and immune complex membranoproliferative glomerulonephritis, or IC-MPGN, in
nephrology; and amyotrophic lateral sclerosis, or ALS, in neurology.

We are also evaluating the administration of systemic pegcetacoplan as an
approach to enabling adeno-associated virus, or AAV, vector administration for
gene therapies. We believe complement inhibition may yield important benefits
when used in combination with AAV-delivered gene therapies, such as increasing
the safety of AAV-delivered gene therapies, decreasing the required AAV dose
needed to achieve a therapeutic effect, and allowing for dosing in patients who
have pre-existing antibodies. In collaboration with commercial and academic
researchers, we are advancing pre-clinical studies to assess the impact of
complement inhibition on AAV-delivered gene therapies. In collaboration with
Spark Therapeutics, Inc., we presented pre-clinical data in May 2022 at the
American Society for Gene Therapy Annual Meeting.

Lastly, we are developing additional product candidates with other routes of
administration and plan to conduct clinical trials of these product candidates,
including the combination of EMPAVELI and a small interfering RNA, or siRNA,
which may offer the potential to reduce the treatment frequency of EMPAVELI by
reducing the production of C3 proteins in the liver. Furthermore, we are
collaborating with Beam Therapeutics, Inc., or Beam, on up to six research
programs focused on C3 and other complement targets in the eye, liver and brain,
using Beam's proprietary base editing technology to discover new treatments for
complement-driven diseases.

Intravitreal Pegcetacoplan. In September 2021, we reported top-line data from
our Phase 3 clinical program consisting of two Phase 3 clinical trials
evaluating intravitreal pegcetacoplan in patients with GA. We refer to these
trials as DERBY and OAKS.

Monthly and every-other-month treatment with intravitreal pegcetacoplan met the
primary endpoint in OAKS, significantly reducing GA lesion growth by 21%
(p=0.0004) and 16% (p=0.0055), respectively, compared to pooled sham at 12
months. Monthly and every-other-month treatment with pegcetacoplan did not meet
the primary endpoint in DERBY, showing a reduction in GA lesion growth of 12%
(p=0.0609) and 11% (p=0.0853) with monthly and every-other-month treatment,
respectively, compared to pooled sham at 12 months. In a prespecified analysis
of the combined DERBY and OAKS studies, monthly and every-other-month treatment
with pegcetacoplan reduced GA lesion growth by 16% (p<0.0001) and 14%
(p=0.0014), respectively, compared to pooled sham at 12 months.

In a prespecified analysis of the primary endpoint, pegcetacoplan demonstrated a
greater effect in patients with extrafoveal lesions at baseline. Patients with
GA typically present first with extrafoveal lesions, which then progress toward
the fovea where central vision is impacted. Under the prespecified analysis, in
the combined studies, monthly and every-other-month treatment with pegcetacoplan
decreased GA lesion growth by 26% (p<0.0001) and 23% (p=0.0002), respectively,
in patients with extrafoveal lesions compared to pooled sham at 12 months.

Intravitreal pegcetacoplan was well-tolerated in both DERBY and OAKS. The pooled
rate of new-onset exudations was 6.0% of patients in the monthly treatment
groups, 4.1% in the every-other-month treatment groups, and 2.4% in the sham
groups. Two cases of confirmed infectious endophthalmitis and one case of
suspected infectious endophthalmitis were observed in the study eye out of a
total of 6,331 injections (0.047%). Thirteen events of intraocular inflammation
were observed in the studies (0.21% per injection). No events of retinal
vasculitis or retinal vein occlusion were observed. There were no clinically
relevant changes in vision for patients who developed infectious endophthalmitis
or intraocular inflammation.

In March 2022, we reported longer-term data from DERBY and OAKS showing that
intravitreal pegcetacoplan continued to reduce GA lesion growth and demonstrate
a favorable safety profile at month 18 (all p-values are nominal). In OAKS,
monthly and every-other-month treatment with intravitreal pegcetacoplan reduced
GA lesion growth by 22% (p<0.0001) and 16% (p=0.0018), respectively. In DERBY,
monthly and every-other-month treatment with intravitreal pegcetacoplan reduced
GA lesion growth by 13% (p=0.0254) and 12% (p=0.0332). Further, pegcetacoplan
demonstrated marked improvements in DERBY during months 6-12 with reductions of
17% with monthly and 16% with every-other-month treatment compared to months
0-6, and the treatment effects were sustained through month 18. The treatment
effects observed in DERBY were comparable with OAKS during months 6-18. The
nominal p-values presented in the month 18 results were calculated using the
same methodology as the month 12 primary endpoint analysis.

At month 18, pegcetacoplan continued to demonstrate a favorable safety profile,
consistent with safety at 12 months and longer-term exposure to intravitreal
injections. The rate of infectious endophthalmitis was 0.044% per injection, and
the rate of intraocular inflammation was 0.23% per injection. Rates of
endophthalmitis and intraocular inflammation continue to be generally in line
with those reported in studies of other intravitreal therapies. No events of
retinal vasculitis or retinal vein occlusion were observed. The combined rate of
new-onset exudations at month 18 was 9.5%, 6.2%, and 2.9% in the pegcetacoplan
monthly, every-other-month, and sham groups, respectively.

Additional data presented at the Association for Research in Vision and
Ophthalmology Annual Meeting in May 2022 showed that monthly and
every-other-month intravitreal pegcetacoplan showed a continuous and clinically
meaningful reduction in the growth of both extrafoveal and foveal lesions at
month 18.

We plan to continue the buildout of our ophthalmology team in the United States
with leadership positions in place across medical affairs, marketing and sales,
and market access, and we have also begun to build out our European team and
affiliates in Germany and Australia.

Systemic Pegcetacoplan. In addition to PNH, for which we obtained approval in
the United States, we are developing systemic pegcetacoplan in several other
indications, including C3G, IC-MPGN, ALS, CAD and HSCT-TMA.

PNH. In January 2020, we announced top-line data from the PEGASUS trial, our
Phase 3 clinical trial evaluating systemic pegcetacoplan in 80 patients with PNH
who exhibited signs of moderate to severe anemia. The PEGASUS trial that showed
that pegcetacoplan met the trial's primary efficacy endpoint, demonstrating
superiority to eculizumab, with a statistically significant improvement in
adjusted means of 3.8 g/dL of hemoglobin at week 16 (p < 0.0001). In May 2021,
we and Sobi announced top-line data from the PRINCE trial, a second Phase 3
clinical trial in patients with PNH who have not been treated with complement
inhibitors within three months before entering the trial, which showed that
pegcetacoplan met both of the co-primary efficacy endpoints of hemoglobin
stabilization and reduction in lactate dehydrogenase or LDH compared to standard
of care, which did not include complement inhibitors, at week 26.

In May 2021, the FDA approved systemic pegcetacoplan for the treatment of adult
patients with PNH. EMPAVELI is approved for use in adults with PNH and can be
used by patients who are either treatment-naïve or who are switching from C5
inhibitors eculizumab or ravulizumab. We believe that EMPAVELI has the potential
to elevate the standard of care in PNH and are seeking to establish EMPAVELI as
the preferred first-line treatment for patients. In the United States, there are
approximately 1,500 patients with PNH currently being treated with C5 inhibitors
and another 150 patients who are expected to be newly diagnosed each year.

In December 2021, the EC approved Aspaveli for the treatment of adults with PNH
who are anemic after treatment with a C5 inhibitor for at least three months. In
January 2022, systemic pegcetacoplan was approved for the treatment of PNH in
Saudi Arabia and Australia, and in March 2022, systemic pegcetacoplan was
approved for the treatment of PNH in the United Kingdom. Systemic pegcetacoplan
is currently marketed under the trade name EMPAVELI™ in the United States, Saudi
Arabia and Australia and Aspaveli in the European Union and United Kingdom.
Under our collaboration and license agreement with Sobi, Sobi has global
co-development and exclusive ex-U.S. commercialization rights for systemic
pegcetacoplan and initiated the commercial launch of Aspaveli in jurisdictions
outside of the United States during the first quarter of 2022. We have
commercialization rights for systemic pegcetacoplan in the United States.

C3G/IC-MPGN. We have initiated and will continue to lead our registrational
program in C3G / IC-MPGN. We dosed the first patient in the NOBLE trial in up to
12 patients with post-kidney transplant recurrence of C3G or IC-MPGN in
September of 2021. In June 2022, we dosed the first patient in our Phase 3
VALIANT trial. VALIANT is a randomized, placebo-controlled, double-blinded,
multi-center Phase 3 trial being conducted in approximately 90 patients who are
12 years of age and older with primary IC-MPGN or C3G. VALIANT is the only study
to include both native kidney patients and patients who have recurrent disease
after receiving a kidney transplant.

ALS. In March 2022, we completed enrollment in MERIDIAN, our randomized,
placebo-controlled Phase 2 clinical trial of systemic pegcetacoplan in adults
with sporadic ALS. The trial enrolled approximately 250 adults. Trial
participants are randomized in a 2:1 ratio to receive pegcetacoplan or placebo
while continuing to receive their existing standard of care treatment for ALS.
After 52 weeks of blinded treatment, all patients in the study will receive
pegcetacoplan. We expect to report top-line data from this trial in mid-2023.

CAD and HSCT-TMA. Sobi will lead development activities for a Phase 3 clinical
trial in CAD and a Phase 2 clinical trial in HSCT-TMA. In early 2022, Sobi dosed
the first patient in the Phase 2 clinical trial of systemic pegcetacoplan in
patients with HSCT-TMA. Sobi expects to begin the Phase 3 trial in patients with
CAD in the second half of 2022.

                                       24

Pipeline. We are developing pegcetacoplan in multiple indications and other product candidates targeting C3 through various routes of administration. We plan to conduct clinical trials of these compounds in additional complement-dependent indications.


We plan to advance up to three new product candidates into clinical development
in 2023. These candidates include a siRNA treatment designed to reduce the
production of C3 proteins by the liver; an oral alternative pathway inhibitor
for certain renal conditions; and APL-2006, a novel compound designed to treat
both GA and wet AMD by intravitreal administration. We also plan to continue our
research activities under collaboration with Beam to develop gene-editing
therapies in multiple therapeutic areas.

Since our commencement of operations in May 2010, we have devoted substantially
all of our resources to developing our proprietary technology, developing
product candidates, undertaking preclinical studies and conducting clinical
trials for pegcetacoplan, building our intellectual property portfolio,
organizing and staffing our company, business planning, raising capital,
preparing for and executing the commercial launch of our products and providing
general and administrative support for these operations.

As of June 30, 2022, we had cash, cash equivalents and marketable securities of
$852.8 million. We believe that our cash and cash equivalents and marketable
securities, along with cash anticipated to be generated from sales of EMPAVELI
and committed development reimbursement payments from Sobi, as of June 30, 2022,
will be sufficient to enable us to fund our current operations at least into the
first quarter of 2024. We have based this estimate on assumptions that may prove
to be wrong, and we could exhaust our available capital resources sooner than we
expect. For additional information see "Liquidity and Capital Resources."

Since the launch of EMPAVELI in May 2021 through June 30, 2022, we have
generated $42.9 million of net product revenue from sales. We have incurred
significant annual net operating losses in each year since our inception and
expect to continue to incur net operating losses for the foreseeable future. Our
net losses were $156.0 million and $219.2 million for the three months ended
June 30, 2022 and, 2021, respectively, and $294.9 million and $402.9 million for
the six months ended June 30, 2022 and 2021, respectively. As of June 30, 2022,
we had an accumulated deficit of $2.0 billion.

Our net losses may fluctuate significantly from quarter to quarter and year to
year. We anticipate that our expenses will increase significantly particularly
as we continue to incur significant commercialization expenses related to
building sales, marketing, medical affairs, manufacturing, distribution and
other commercial infrastructure associated with the commercialization of
EMPAVELI for the treatment of PNH. We are incurring significant expenses for the
commercialization and further development of intravitreal pegcetacoplan. In
addition, we expect our expenses to increase if and as we continue to develop
and conduct our ongoing and planned clinical trials of pegcetacoplan and our
other product candidates; initiate and continue research and preclinical and
clinical development efforts for any future product candidates; seek to identify
and develop additional product candidates for complement-dependent diseases;
seek regulatory and marketing approvals for our product candidates that
successfully complete clinical trials, if any; establish sales, marketing,
distribution and other commercial infrastructure to commercialize any additional
products for which we may obtain marketing approval; require the manufacture of
larger quantities of product candidates for clinical development and,
potentially, commercialization; maintain, expand and protect our intellectual
property portfolio; hire and retain additional personnel, such as clinical,
quality control, regulatory and scientific personnel; add operational, financial
and management information systems and personnel, including personnel to support
our product development and add equipment and physical infrastructure to support
our research and development programs and commercialization.

We temporarily closed our facilities in March 2020 in respect to the COVID-19
pandemic. We have since reopened our facilities, subject to compliance with
strict safety guidelines, but many of our employees continue to work remotely.
As of the date of this Quarterly Report on Form 10-Q, we do not believe that the
COVID-19 pandemic has had a significant impact upon our operations, including
sales of EMPAVELI (except to the extent that our representatives' access to the
offices of health care providers was limited during the omicron wave of the
pandemic), our ongoing clinical trials (except for the delay of the clinical
trials for ALS) and the manufacture and supply of our product candidates.

SFJ Agreement


On February 28, 2019, we entered into a development funding agreement, which we
refer to as the SFJ agreement, with SFJ Pharmaceuticals Group, or SFJ, under
which SFJ agreed to provide funding to us to support the development of systemic
pegcetacoplan for the treatment of patients with PNH. Pursuant to the agreement,
SFJ paid us $60.0 million following the signing of the agreement and agreed to
pay us up to an additional $60.0 million in the aggregate in three equal
installments upon the achievement of specified development milestones with
respect to our Phase 3 program for pegcetacoplan in PNH and subject to our
having cash resources at the time sufficient to fund at least 10 months of our
operations.

On June 7, 2019, we amended the SFJ agreement, which we refer to as the SFJ amendment. Under the SFJ amendment, SFJ agreed to make an additional $20.0 million funding payment to us to support the development of systemic pegcetacoplan for the treatment of patients with PNH.

                                       25

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

Table of Contents

On June 27, 2019, we received $40.0 million from SFJ, consisting of $20.0 million as the first installment of the additional $60.0 million upon the achievement of a milestone and the $20.0 million payable under the SFJ amendment.


In September 2019, we received $20.0 million from SFJ, as the second installment
of the additional $60.0 million due to the achievement of a milestone and in
January 2020 received the remaining $20.0 million installment of the additional
$60.0 million upon the announcement of the results of the PEGASUS phase 3 trial.

Under the SFJ agreement, following regulatory approvals by the FDA and the EMA
for the use of systemic pegcetacoplan as a treatment for PNH, we paid SFJ $4.0
million in 2021 in connection with the FDA approval in May 2021. In 2022, we
paid SFJ $16.5 million which consisted of $5.0 million in connection with the
EMA approval in December 2021 and $11.5 million in connection with the one-year
anniversary of the FDA approval, respectively. We are obligated to pay SFJ an
additional $439.5 million in the aggregate in six additional annual payments
with the majority of the payments being made from the third anniversary to the
sixth anniversary of regulatory approval. For the remainder of 2022, we are
obligated to pay a total of $18.0 million in connection with the one-year
anniversary of the EMA approval.

Collaboration Agreement with Sobi


On October 27, 2020, we entered into the Sobi collaboration agreement,
concerning the development and commercialization of pegcetacoplan and specified
other structurally and functionally similar compstatin analogues or derivatives
for use systemically or for local non-ophthalmological administration,
collectively referred to as the licensed products. We granted Sobi an exclusive
(subject to certain rights retained by us), sublicensable license of certain
patent rights and know-how to develop and commercialize licensed products in all
countries outside of the United States. We retained the right to commercialize
licensed products in the United States, and, subject to specified limitations,
to develop licensed products worldwide for commercialization in the United
States. Under the agreement, Sobi made an upfront payment of $250.0 million in
November 2020, and agreed to pay up to an aggregate of $915.0 million upon the
achievement of specified one-time regulatory and commercial milestone events,
including a $50.0 million milestone which would be payable following the first
regulatory and reimbursement approval of system pegcetacoplan in any major
European country, and to reimburse us for up to $80.0 million in development
costs. In January 2021 we received a $25.0 million development reimbursement
payment from Sobi and in January 2022 we received a $20.0 million development
reimbursement payment. We expect to receive the balance annually in installments
over the next two years, subject to certain conditions.

European Commission approval of systemic pegcetacoplan for the treatment of PNH
was received in December 2021. In March 2022, we earned a $50.0 million payment
from Sobi related to the first regulatory and reimbursement milestone in Europe.
We considered the reimbursement approval to be probable at December 31, 2021,
and recorded revenue at that time. We received the $50.0 million payment in
April 2022. We are also entitled to receive tiered, double-digit royalties
(ranging from high teens to high twenties) on sales of licensed products outside
of the United States, subject to customary deductions and third-party payment
obligations, until the latest to occur of: (i) expiration of the last-to-expire
of specified licensed patent rights; (ii) expiration of regulatory exclusivity;
and (iii) ten (10) years after the first commercial sale of the applicable
licensed product, in each case on a licensed product-by-licensed product and
country-by-country basis. We remain responsible for our license fee obligations
(including royalty obligations) to the University of Pennsylvania and for our
payment obligations to SFJ.

Financial Operations Overview

Revenue

Our revenues consist of product sales of EMPAVELI and revenues derived from our collaboration arrangement with Sobi.


Revenue is recognized when, or as, we satisfy a performance obligation by
transferring a promised good or service to a customer. An asset is transferred
when, or as, the customer obtains control of that asset. For performance
obligations that are satisfied over time, we recognize revenue using an input or
output measure of progress that best depicts the satisfaction of the relevant
performance obligation.

Product Revenues

Product revenue is derived from our sales of our commercial product, EMPAVELI, in the United States.

Licensing and Other Revenue


Licensing and other revenue is derived from our collaboration agreement with
Sobi concerning the development and commercialization of pegcetacoplan and
specified other compstatin analogues or derivatives for use systemically or for
local non-ophthalmic administration.

Research and Development Expenses


Research and development expenses consist primarily of costs incurred for our
research activities, including our drug discovery efforts, and the development
of our product candidates, which include:

employee-related expenses including salaries, bonuses, benefits and share-based
compensation expense related to individuals performing research and development
activities;

expenses incurred under agreements with third parties, including contract
research organizations, or CROs, that conduct clinical trials and research and
development activities on our behalf, and contract manufacturing organizations
that manufacture quantities of drug supplies for both our preclinical studies
and clinical trials;

the cost of consultants, including share-based compensation expense; and

various other expenses incident to the management of our preclinical studies and clinical trials.


Research and development costs are expensed as incurred. Nonrefundable advance
payments for goods or services to be received in the future for use in research
and development activities are deferred and capitalized. The capitalized amounts
are expensed as the related goods are delivered or the services are performed.
We have not provided program costs since inception because historically we have
not tracked or recorded our research and development expenses on a
program-by-program basis.

The successful development of our product candidates in clinical development is
highly uncertain. Accordingly, at this time, we cannot reasonably estimate the
nature, timing and costs of the efforts that will be necessary to complete the
remainder of the clinical development of these product candidates. We are also
unable to predict when, if ever, material net cash inflows will commence from
pegcetacoplan in other jurisdictions and indications or any other potential
product candidates. This is due to the numerous risks and uncertainties
associated with developing therapeutics, including the uncertainties of:

establishing an appropriate safety profile in preclinical studies;

successful enrollment in, and completion of clinical trials;

receipt of marketing approvals from applicable regulatory authorities;

establishing commercial manufacturing capabilities or making arrangements with third-party manufacturers;

obtaining and maintaining patent and trade secret protection and regulatory exclusivity for our product candidates;

launching commercial sales of the products, if and when approved, whether alone or in collaboration with others; and

an acceptable safety profile of the products following approval.

A change in the outcome of any of these variables with respect to the development of any of our product candidates would significantly change the costs and timing associated with the development of that product candidate.


Research and development activities are central to our business model. Product
candidates in later stages of clinical development generally have higher
development costs than those in earlier stages of clinical development,
primarily due to the increased size and duration of later-stage clinical trials.
We expect research and development costs to increase for the foreseeable future
as our product candidate development programs progress. However, we do not
believe that it is possible at this time to accurately project total
program-specific expenses through commercialization. There are numerous factors
associated with the successful commercialization of any of our product
candidates, including future trial design and various regulatory requirements,
many of which cannot be determined with accuracy at this time based on our stage
of development. Additionally, future commercial and regulatory factors beyond
our control will impact our clinical development programs and plans.

General and Administrative Expenses


General and administrative expenses consist primarily of employee-related
expenses including salaries, bonuses, benefits and share-based compensation.
Other significant costs include facility costs not otherwise included in
research and development expenses, legal fees relating to patent and corporate
matters, and fees for accounting and consulting services.

We anticipate that our general and administrative expenses will increase in the
future to support the commercialization of EMPAVELI in PNH and, if approved,
intravitreal pegcetacoplan, continued research and development activities,
potential commercialization of our other product candidates and costs of
operating as a public company.

Critical Accounting Policies and Estimates


This discussion and analysis of our financial condition and results of
operations is based on our financial statements, which we have prepared in
accordance with U.S. generally accepted accounting principles. The preparation
of these financial statements requires us to make estimates and assumptions that
affect the reported amounts of assets and liabilities and the disclosure of
contingent assets and liabilities at the date of the financial statements, as
well as the reported amounts of expenses during the reported periods. On an
ongoing basis, we evaluate our estimates and judgments, including those related
to product revenue, licensing revenue, costs of research collaboration
arrangements, inventory, accrued research and development expenses, convertible
notes, capped call transactions and the development derivative liability and
development liability, which we described in our 2021 Annual Report on Form
10-K. We base our estimates on historical experience and on various other
factors that we believe are reasonable under the circumstances, the results of
which form the basis for making judgments about the carrying value of assets and
liabilities that are not readily apparent from other sources. Actual results may
differ from these estimates under different assumptions or conditions.

Our significant accounting policies are described in Note 2 of Part I, Item 1 of
this Quarterly Report on Form 10-Q and in Part I, Item 7, "Critical Accounting
Policies and Estimates" in our 2021 Annual Report on Form 10-K. There have been
no changes to our critical accounting policies and estimates since our 2021
Annual Report on Form 10-K.

Research and development expenses decreased by $44.3 million to $101.7 million
for the three months ended June 30, 2022 from $145.9 million for the three
months ended June 30, 2021, a decrease of 30%. The decrease was primarily
attributable to the $50.0 million cost of research collaboration associated with
the collaboration arrangement with Beam Therapeutics, Inc., or Beam, recorded in
the prior period, a decrease of $10.6 million in contract manufacturing expenses
due primarily to the timing of drug supply and analytical activity, a decrease
of $7.2 million in clinical trial costs due to the completion of our Phase 3
DERBY and OAKS trials, and a decrease of $0.6 million in research and innovation
costs. The decrease was partially offset by a $13.2 million increase in
personnel related costs due to having more employees in the three months ended
June 30, 2022, a decrease of $9.1 million in contra research and development
expense related to the Sobi transaction, and a $1.8 million increase in other
research and development supporting activities primarily driven by regulatory,
quality and medical affairs expenses.

General and Administrative Expenses


General and administrative expenses increased by $14.2 million to $63.2 million
for the three months ended June 30, 2022, from $49.0 million for the three
months ended June 30, 2021, an increase of 29%. The increase was primarily
attributable to higher employee related costs of $7.9 million, an increase in
professional and consulting fees and general commercial preparation activities
of $4.3 million, higher office costs of $2.0 million, an increase in travel
related expenses of $0.9 million, and higher insurance costs of $0.1 million.
The increase was partially offset by lower director stock option compensation of
$1.0 million. The increase in employee related costs of $7.9 million consisted
of a $6.4 million increase in salaries and benefits primarily due to the higher
number of employees in the current period, an increase of $1.3 million in
recruiting expenses, and $0.2 million related to stock compensation expense
associated with the grant of stock options and restricted stock units to
employees. The increase in other professional and consulting fees and general
commercial preparation activities of $4.3 million was primarily related to
higher commercialization related activity of $6.8 million, and was partially
offset by a decrease in general professional fees of $2.5 million.

Loss from Remeasurement of Development Derivative Liability


Loss from remeasurement of development derivative liability was $21.2 million
for the three months ended June 30, 2021. On December 15, 2021, the development
derivative liability was reclassified to development liability and no longer
remeasured to fair value at the end of each quarter. See Note 6 Development
Liability and Development Derivative Liability in the Notes to Unaudited
Condensed Consolidated Financial Statements included in Item 1 of this Report
for additional details regarding the development derivative liability.

Interest Income


Interest income was $1.4 million for the three months ended June 30, 2022, an
increase of $1.3 million, compared to $0.1 million for the three months ended
June 30, 2021. The increase in interest income was primarily attributable to
purchases of marketable securities during the month ended June 30, 2022.

Table of Contents

Interest Expense


Interest expense was $8.4 million for the three months ended June 30, 2022 and
$3.8 million for the three months ended June 30, 2021. The increase is primarily
due to accretion of the development liability discount related to the SFJ
agreement in the current period.

Other Income/(Expense), Net

Other income/(expense), net, increased $0.2 million during the three months ended June 30, 2022 compared to the three months ended June 30, 2021. The increase was primarily due to an increase in other taxes and foreign currency revaluation gains.


Income Tax Expense

Income tax expense increased by $0.5 million during the three months ended June
30, 2022 compared to the three months ended June 30, 2021. The increase
primarily pertained to federal and state income taxes where the utilization of
net operating losses and research and development tax credits are limited.

Research and development expenses decreased by $37.4 million to $192.6 million
for the six months ended June 30, 2022 from $230.0 million for the six months
ended June 30, 2021, a decrease of 16%. The decrease was primarily attributable
to the $50.0 million cost of research collaboration associated with the Beam
arrangement recorded in the prior period, a decrease of $22.1 million in
contract manufacturing expenses due primarily to the timing of drug supply and
analytical activity, a decrease of $11.3 million in clinical trial costs due to
the completion of our Phase 3 DERBY and OAKS trials, and decreases of $0.2
million in research and innovation costs and $0.2 million in pre-clinical study
expenses. The decrease was partially offset by a $26.4 million increase in
personnel related costs due to having more employees in the six months ended
June 30, 2022, a decrease of $12.2 million in contra research and development
expense related to the Sobi transaction, and a $7.8 million increase in other
research and development supporting activities primarily driven by regulatory,
quality and medical affairs expenses.

General and Administrative Expenses


General and administrative expenses increased by $24.9 million to $114.4 million
for six months ended June 30, 2022, from $89.5 million for the six months ended
June 30, 2021, an increase of 28%. The increase was primarily attributable to an
increase in employee related costs of $14.5 million, an increase in professional
and consulting fees and general commercial preparation activities of $9.0
million, an increase in travel related expenses of $1.8 million, higher office
costs of $1.1 million, and an increase in insurance costs of $0.3 million. The
increase was partially offset by lower director stock option compensation of
$1.8 million. The increase in employee related costs of $14.5 million consisted
of a $7.4 million increase in salaries and benefits primarily due to the higher
number of employees in the current period, an increase of $5.2 million related
to stock compensation expense associated with the grant of stock options and
restricted stock units to employees, and an increase of $1.8 million in
recruiting expenses. The increase in other professional and consulting fees and
general commercial preparation activities of $9.0 million primarily related to
higher commercialization related activity of $10.7 million, partially offset by
a decrease in general professional fees of $1.7 million.

Loss on Conversion of Debt


Loss on conversion of debt was $39.5 million for the six months ended June 30,
2021. We did not have any conversions of debt during the six months ended June
30, 2022. See Note 7 Long-term Debt in the Notes to Unaudited Condensed
Consolidated Financial Statements included in Item 1 of this Report for
additional details regarding the conversion of debt in the six months ended June
30, 2021.

Loss from Remeasurement of Development Derivative Liability


Loss from remeasurement of development derivative liability was $38.3 million
for the six months ended June 30, 2021. On December 15, 2021, the development
derivative liability was reclassified to development liability and no longer
remeasured to fair value at the end of each quarter. See Note 6 Development
Liability and Development Derivative Liability in the Notes to Unaudited
Condensed Consolidated Financial Statements included in Item 1 of this Report
for additional details regarding the development derivative liability.

Interest Income

                                       31

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

Table of Contents

Interest income was $1.5 million for the six months ended June 30, 2022, an increase of $1.3 million compared to $0.2 million for the six months ended June 30, 2021. The increase in interest income was primarily attributable to purchases of marketable securities during the month ended June 30, 2022.

Interest Expense


Interest expense was $17.0 million for the six months ended June 30, 2022 and
$7.9 million for the six months ended June 30, 2021. The increase was primarily
due to accretion of the development liability discount related to the SFJ
agreement in the current period.

Other (Expense)/Income, Net


Other (expense)/income, net during the six months ended June 30, 2022 decreased
$1.6 million compared to the six months ended June 30, 2021. The decrease was
primarily due to foreign currency revaluation losses.

Income Tax Expense


Income tax expense increased by $1.7 million during the six months ended June
30, 2022 compared to the six months ended June 30, 2021. The increase primarily
pertained to federal and state income taxes where the utilization of net
operating losses and research and development tax credits are limited.


Liquidity and Capital Resources

Sources of Liquidity


To date, we have financed our operations primarily through $1.6 billion in net
proceeds from public offerings of our common stock, including our initial public
offering, or IPO, $535.8 million in net proceeds from offerings of Convertible
Notes, a $250.0 million up-front payment and a $25.0 million development
reimbursement payment from Sobi pursuant to the Sobi collaboration agreement,
$112.6 million in proceeds from the private placement of shares of our
convertible preferred stock prior to our IPO, $140.0 million under the SFJ
agreement, $20.0 million in proceeds from borrowings under a term loan facility
with Silicon Valley Bank, and $7.0 million in proceeds from our issuance and
sale of a promissory note. We have repaid the term loan facility and the
promissory note in full, and we exchanged $327.2 million of aggregate principal
amount of our Convertible Notes for shares of our common stock in January 2021
and July 2021.

In April 2018, we issued and sold 5,500,000 shares of our common stock in a follow-on public offering at a public offering price of $25.50 per share for net proceeds of $131.2 million, after deducting underwriting discounts and commissions of $8.4 million and offering expenses of $0.5 million.

In March 2019, we issued and sold 6,900,000 shares of our common stock in a follow-on offering at a public offering price of $17.00. We received net proceeds of $109.6 million after deducting underwriting discounts and commissions of $7.0 million and offering costs of $0.7 million.

In September 2019, we completed a private offering of $220.0 million aggregate principal amount of Convertible Notes, or the 2019 Convertible Notes. We received net proceeds of approximately $212.9 million after deducting the initial purchasers' discounts and commissions and offering costs of $7.1 million.


In January 2020, we issued and sold 10,925,000 shares of our common stock in a
follow-on offering at a public offering price of $37.00, including 1,425,000
shares sold pursuant to the underwriters' exercise in full of their option to
purchase additional shares of common stock. We received total net proceeds of
$381.4 million after deducting underwriting discounts and commissions of $22.2
million and offering costs of $0.5 million.

In May 2020, we completed a private offering of $300.0 million aggregate principal amount of Convertible Notes, or the 2020 Convertible Notes. We received net proceeds of approximately $322.9 million, which included accrued interest March 15, 2020 to, but not including May 12, 2020, and the initial purchasers' discounts and commissions and offering costs of $6.0 million.


In January 2021, we entered into separate, privately negotiated exchange
agreements with certain holders of our 2019 Convertible Notes. Under the terms
of these exchange agreements, the holders exchanged approximately $126.1 million
in aggregate principal amount of 2019 Convertible Notes held by them for an
aggregate of 3,906,869 shares of our common stock. These exchange transactions
closed in January 2021.

In July 2021, we entered into separate, privately negotiated exchange agreements
to modify the conversion terms with certain holders of the Convertible Notes.
Under the terms of these exchange agreements, the holders exchanged
approximately $201.1 million in aggregate principal amount of Convertible Notes
held by them for an aggregate of 5,992,217 shares of common stock. These
exchange transactions closed in July 2021.

In November 2021, we issued and sold 10,062,500 shares of our common stock in a
follow-on offering at a public offering price of $40.00, including 1,312,500
shares sold pursuant to the underwriters' exercise in full of their option to
purchase additional shares of common stock. We received total net proceeds of
$380.4 million after deducting underwriting discounts and commissions of $22.1
million and offering costs of $0.6 million.

In March 2022, we issued and sold 8,563,830 shares of our common stock in a
follow-on offering at a public offering price of $47.00, including 1,117,021
shares sold pursuant to the underwriters' exercise in full of their option to
purchase additional shares of common stock. We received total net proceeds of
$380.1 million after deducting underwriting discounts and commissions of $22.1
million and offering costs of $0.3 million.

In July 2022, we entered into separate, privately negotiated exchange agreements
with certain holders of Convertible Notes pursuant to which the holders
exchanged approximately $98.1 million in aggregate principal amount of
Convertible Notes held by them for an aggregate of 3,027,018 shares of common
stock. These exchange transactions closed in August 2022. Following closing of
the exchange transactions, there was $93.9 million in aggregate principal amount
of Convertible Notes outstanding and held by third parties. We held in treasury
Convertible Notes in aggregate principal amount of $425.4 million, which notes
had not been cancelled.

In addition to our existing cash, cash equivalents and marketable securities, we
anticipate cash to be generated from sales of EMPAVELI and committed development
reimbursement payments from Sobi. Our ability to earn these milestone payments
and the timing of earning these payments is dependent upon the outcome of our
research and development and commercialization activities and is uncertain at
this time.

The capped call transactions that we entered into concurrently with the issuance
of the Convertible Notes are expected generally to reduce the potential dilution
to our common stock upon any conversion of the Convertible Notes and/or offset
any cash payments we are required to make in excess of the principal amount of
converted convertible notes, as the case may be, in the event that the market
price per share of our common stock, as measured under the terms of the capped
call transactions, is greater than the strike price of the capped call
transactions, which is initially $39.4625, the conversion price of the
convertible notes.

Refer to Note 7 Long-term Debt in the Notes to Unaudited Condensed Consolidated Financial Statements in Part I, Item I of this Form 10-Q for additional information regarding the convertible notes and capped call transactions.

Net Cash Provided by Financing Activities


Net cash provided by financing activities was $372.0 million during the six

follow-on common stock offering in March 2022 of $380.1 million, $8.8 million
proceeds upon the exercise of stock options and $2.5 million proceeds from the
issuance of common stock under the employee stock purchase plan partially offset
by payments of $16.5 million for the development liability as well as $3.0

purchase plan, offset by $4.0 million for the payment on the development
derivative liability as well as $1.2 million for the payment of employee tax
withholding related to equity-based compensation.

Funding Requirements


We expect our expenses to increase in connection with our ongoing activities,
particularly as we continue to incur significant commercialization expenses
related to product manufacturing, marketing, sales and distribution of EMPAVELI
and pre-commercialization activities related to intravitreal pegcetacoplan for
GA. In addition, we expect our expenses to increase as we continue the research
and development of, and seek marketing approval for, our product candidates.
Accordingly, we will need to obtain substantial additional funding in connection
with our continuing operations. If we are unable to raise capital when needed or
on attractive terms, we would be forced to delay, reduce or eliminate our
research and development programs or commercialization efforts.

We believe that our cash, cash equivalents and marketable securities as of June
30, 2022, along with cash anticipated to be generated from sales of EMPAVELI and
committed development reimbursement payments from Sobi, will enable us to fund
our operating expenses and capital expenditure requirements at least into the
first quarter of 2024. We have based this estimate on assumptions that may prove
to be wrong, and we may use our available capital resources sooner than we
currently expect. We are devoting resources to the building of a commercial
infrastructure for intravitreal pegcetacoplan for GA. We will incur substantial
additional commercialization expenses for intravitreal pegcetacoplan if we
obtain regulatory approval for GA. We are also devoting additional resources to
the development of our product candidates. We will need to seek additional
funding to conduct these activities. Because of the numerous risks and
uncertainties associated with the commercialization of EMPAVELI, the development
of intravitreal pegcetacoplan and other product candidates, and because the
extent to which we may enter into collaborations with third parties for the
development of these product candidates is unknown, we are unable to estimate
the amounts of increased capital outlays and operating expenses associated with
completing the research and development of our product candidates. Our future
funding requirements will depend on many factors, including:

our ability to successfully commercialize and sell EMPAVELI in the United States;

the cost of and our ability to effectively establish and maintain, the
commercial infrastructure and manufacturing capabilities required to support the
commercialization of EMPAVELI, systemic pegcetacoplan and intravitreal
pegcetacoplan and any other products for which we receive marketing approval
including product sales, medical affairs, marketing, manufacturing and
distribution;

the scope, progress, timing, costs and results of clinical trials of, and research and preclinical development efforts for pegcetacoplan, and future product candidates;

                                       34

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

Table of Contents

our ability to maintain a productive collaborative relationship with Sobi with
respect to systemic pegcetacoplan, including our ability to achieve milestone
payments under our agreement with Sobi;

our ability to identify additional collaborators for any of our product candidates and the terms and timing of any collaboration agreement that we may establish for the development and any commercialization of such product candidates;

the number and characteristics of future product candidates that we pursue and their development requirements;

the outcome, timing and costs of clinical trials and of seeking regulatory approvals of pegcetacoplan in other jurisdictions and indications and other product candidates we may pursue

the costs of commercialization activities for pegcetacoplan in additional indications or any of our other product candidates that receive marketing approval to the extent such costs are not the responsibility of our collaborators, including the costs and timing of establishing product sales, marketing, distribution and manufacturing capabilities;

subject to receipt of marketing approval, revenue, if any, received from commercial sales of pegcetacoplan in other jurisdictions and indications and our other product candidates;

our headcount growth and associated costs as we expand our research and development and establish a commercial infrastructure;

the costs of preparing, filing and prosecuting patent applications, maintaining and protecting our intellectual property rights and defending against intellectual property related claims;

the effect of competing technological and market developments;

the effect of the COVID-19 pandemic on the healthcare system and the economy generally and on our clinical trials and other operations specifically;

our ability to obtain adequate reimbursement for EMPAVELI in the United States or any other product we commercialize; and

the costs of operating as a public company.


Until such time, if ever, as we can generate substantial product revenues, we
expect to finance our cash needs through a combination of equity offerings, debt
financings, collaborations, strategic alliances and licensing arrangements. We
currently do not have any committed external source of funds. To the extent that
we raise additional capital through the sale of equity or convertible debt
securities, our stockholders' ownership interests will be diluted, and the terms
of these securities may include liquidation or other preferences that adversely
affect our stockholders' rights. Debt financing, if available, would result in
fixed payment obligations and may involve agreements that include restrictive
covenants that limit our ability to take specific actions, such as incurring
additional debt, making capital expenditures or declaring dividends, that could
adversely impact our ability to conduct our business.


If we raise funds through collaborations, strategic alliances or licensing
arrangements with third parties, we may have to relinquish valuable rights to
our technologies, future revenue streams, research programs or product
candidates or to grant licenses on terms that may not be favorable to us. If we
are unable to raise additional funds through equity or debt financings when
needed, we may be required to delay, limit, reduce or terminate our product
development or future commercialization efforts or grant rights to develop and
market product candidates that we would otherwise prefer to develop and market
ourselves.
