Overview



We are a biopharmaceutical company driven by our mission to discover, develop
and deliver life-changing treatments that provide hope to underserved patient
communities, starting with sickle cell disease, or SCD. Founded in 2011, our
goal is to transform the treatment and care of SCD, a lifelong, devastating
inherited blood disorder that is marked by red blood cell destruction and
occluded blood flow and hypoxia, which leads to anemia, stroke, multi-organ
failure, severe pain crises, and shortened patient life span. SCD is also marked
by a historical lack of understanding, investment and attention. Although the
fundamental cause of SCD has been understood for decades, therapeutic innovation
and access to care have historically lagged compared to many other rare
diseases. For example, there are approximately three times more individuals in
the United States living with SCD than cystic fibrosis. However, since the
enactment of the Orphan Drug Act passed in 1983, only four drugs have been
approved for SCD compared to at least 15 drugs approved for cystic fibrosis. As
a result of the lack of treatment options, patients with SCD suffer serious
morbidity and premature mortality.

We continue to make progress on our mission to bring innovative therapies to the
SCD community. Our first medicine, Oxbryta, an oral therapy taken once daily, is
the first and only FDA-approved treatment that directly inhibits sickle
hemoglobin polymerization, the root cause of the sickling and destruction of red
blood cells in SCD. Oxbryta was granted accelerated approval by the U.S. Food
and Drug Administration, or FDA, in November 2019, for the treatment of SCD in
adults and children 12 years of age and older, and we have since continued to
grow Oxbryta commercially, with the net number of patients taking Oxbryta
increasing each quarter. In addition, in October 2021, Oxbryta was recognized by
Prix Galien USA with the prestigious Best Biotechnology Product award.

We have also been working to expand Oxbryta's reach to patients at younger ages
as we believe early intervention is critically important for SCD patients.
Starting a disease-modifying therapy earlier in life could potentially help
prevent symptoms and end-organ damage that occurs over time in SCD patients.
This could potentially improve the daily lives of children and their families,
improve patient outcomes and lead to less utilization of healthcare, reducing
healthcare costs for patients and families, and the overall healthcare system.
In December 2021, the FDA granted accelerated approval to expand Oxbryta's
indication for the treatment of SCD to children ages 4 to less than 12 years.
The FDA also approved Oxbryta tablets for oral suspension, a dispersible,
once-daily tablet dosage form suitable for patients ages 4 to less than 12 years
as well as for older patients who have difficulty swallowing whole tablets. We
will continue to study Oxbryta in patients as young as 6 months old, as we look
to potentially further expand access to Oxbryta.

Worldwide, there are millions of people living with SCD, which occurs
predominantly in populations of African, Middle Eastern and South Asian descent
and has an estimated global incidence of 250,000 to 300,000 births annually. We
are executing what we view as a thoughtful and sustainable approach and will
consider distribution and funding approaches to potentially provide access to
our products globally, including in sub-Saharan Africa and India. Across our
current focus areas of the United States, Europe, the Gulf Cooperation Council,
or GCC, region of the Middle East, and Latin America, we believe there is an
opportunity to bring Oxbryta to more than 350,000 people living with SCD in the
next several years.

With respect to Europe, the European Commission, or EC, granted marketing
authorization for Oxbryta in February 2022 for the treatment of hemolytic anemia
(which is low hemoglobin due to red blood cell destruction) due to SCD in adult
and pediatric patients 12 years of age and older as monotherapy or in
combination with hydroxycarbamide (hydroxyurea), and such authorization includes
all member states of the European Union, or EU, as well as the additional member
states of the European Economic Area (Iceland, Liechtenstein and Norway), or
EEA. In July 2022, the MHRA granted our application using the EC Decision
Reliance Procedure for a

                                       20
--------------------------------------------------------------------------------


Great Britain marketing authorization for Oxbryta for the treatment of hemolytic
anemia due to SCD in adult and pediatric patients 12 years of age and older as
monotherapy or in combination with hydroxycarbamide (hydroxyurea).

To provide early access to patients prior to potentially receiving marketing
approval, we established early access and named patient programs for eligible
SCD patients outside the United States, including in the United Kingdom, France,
Germany and Brazil. The United Kingdom and France have the majority of SCD
patients in Europe.

Under the exclusive agreement with our distribution partner, Biopharma-Middle
East and Africa, or Biopharma-MEA, we continue to advance efforts to expand
access to Oxbryta in the six countries that make up the GCC region (Bahrain,
Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates, or UAE). In the
GCC, the U.S. approval of Oxbryta can be referenced to allow access to the
medicine while health authorities conduct their reviews. In the third quarter of
2021, we were granted marketing authorization for Oxbryta by the Ministry of
Health and Prevention (MOHAP) in the UAE for the treatment of SCD in adults and
children 12 years of age and older, with the UAE being the first country outside
of the U.S. to grant regulatory approval of Oxbryta. Oxbryta has also been
approved in Oman for the treatment of SCD in adults and children 12 years of age
and older.

We have ongoing and planned clinical trials in multiple countries to further
evaluate the safety and efficacy of Oxbryta, including trials designed to
demonstrate that improving hemoglobin and reducing hemolysis leads to an
improvement in organ dysfunction. These trials include the Phase 2a HOPE-KIDS 1
Study, an open-label, single- and multiple-dose trial evaluating the safety,
tolerability, pharmacokinetics and exploratory treatment effect of Oxbryta in
pediatric patients as young as 6 months of age. These trials also include the
HOPE-KIDS 2 Study, a post-approval confirmatory study we initiated in December
2019 as a condition of the accelerated approval of Oxbryta in the United States,
that is using transcranial Doppler, or TCD, flow velocity to seek to demonstrate
a decrease in stroke risk in children with SCD 2 to 15 years of age.

Beyond Oxbryta, we are engaged in other research and development activities. Our
development program includes inclacumab, a P-selectin inhibitor, currently in
Phase 3 clinical development to investigate its potential to reduce the
incidence of painful vaso-occlusive crises, or VOCs, and resulting hospital
admissions. We are also advancing GBT021601, or GBT601, our next generation
hemoglobin polymerization inhibitor, which was discovered by our scientists and
is being studied in Phase 1 and Phase 2/3 clinical trials. The Phase 1 clinical
trial was completed in late 2021 and, based on patient demand, then restarted in
the second quarter of 2022 to evaluate a higher daily dose of GBT601 than
previously studied. In June 2022, we announced the initiation of the Phase 2
portion of the planned Phase 2/3 clinical trial of GBT601, with the primary
outcome measure of the Phase 2 portion being the number of patients with a
change from baseline in hemoglobin, or Hb, levels through Week 12. In addition,
our drug discovery teams continue to work on new targets to potentially develop
the next wave of treatments for SCD.

As part of our efforts to build our pipeline, we have entered into in-license
and collaboration agreements and regularly evaluate opportunities to in-license,
acquire or invest in new business, technology or assets or engage in related
discussions with other business entities.

We licensed inclacumab from F. Hoffmann-La Roche Ltd. and Hoffmann-La Roche Inc.
(together, "Roche") under the License Agreement we entered into in August 2018,
or Roche Agreement. Prior to licensing inclacumab to us, Roche conducted
clinical studies that enrolled more than 700 non-SCD patients and demonstrated
an encouraging pharmacokinetic, safety, and tolerability profile for inclacumab.
We expect to be able to leverage the safety data from Roche's prior clinical
studies, as we proceed with our development of inclacumab as a potential
treatment to reduce the frequency of VOCs in patients with SCD and to reduce the
hospital VOC readmission rate for patients that require inpatient treatment for
an initial VOC episode. In July 2021, we announced the initiation of two pivotal
Phase 3 clinical trials of inclacumab. One study is a chronic prevention study
with the primary endpoint of the rate of VOCs over a 48-week treatment period,
and the other study is focusing on hospital readmissions with the primary
endpoint of the rate of readmission to hospitals for VOC within 90 days
following an initial hospitalization for a VOC.

We also have an ongoing early-stage research program under our collaboration
with Syros Pharmaceuticals, Inc., or Syros, under a License and Collaboration
Agreement, or the Syros Agreement, entered into in December 2019, to discover,
develop and commercialize novel therapies for SCD and beta thalassemia. We are
currently exploring orally available, small molecule drugs designed to
upregulate fetal hemoglobin. Under the Syros Agreement, we have an option to
obtain an exclusive worldwide license to develop, manufacture and commercialize
any compounds or products resulting from the collaboration, subject to Syros'
option to co-promote the first product in the United States.

In addition, we entered into a license agreement with Sanofi S.A., or Sanofi, in
March 2021, under which we received an exclusive license under certain
intellectual property controlled by Sanofi to use, develop, manufacture,
commercialize and otherwise exploit certain compounds, including compounds
directed against or that modulate one of two specified targets, or Licensed
Compounds, for the treatment of human diseases worldwide. We currently intend to
explore the Licensed Compounds for the potential treatment of SCD, and we
believe the mechanisms are distinct and potentially complementary to that of
Oxbryta.

In March 2020, the Centers for Disease Control and Prevention, or CDC, declared
a global pandemic related to SARS-CoV-2, the virus that causes coronavirus
disease 2019, or COVID-19, and the pandemic has impacted our business, including
our commercialization of Oxbryta and our research and development activities.
For example, we have continued to see significantly lower rates of weekly new
patient prescriptions for Oxbryta compared to a peak in early March 2020, and we
expect the rate of new patient

                                       21
--------------------------------------------------------------------------------


prescriptions may remain at these lower levels depending on the course of the
pandemic. While we have resumed most of our operations that were temporarily
paused at the beginning of the pandemic, our approach in some cases has changed
to adapt to the new environment, such as the increased use of digital and
internet-based education and outreach to engage with healthcare professionals,
or HCPs, and payors. We do not know how the adjustments we have made in our
operations or the pandemic in general will impact our business in the long term.
Notably, the pandemic has not significantly impacted our supply of Oxbryta. We
continue to believe we have an adequate supply of Oxbryta to sustain estimated
patient need through 2022, and we are continuing to produce Oxbryta tablets.

Overall, our business model is aligned with our social purpose, which is
centered on highlighting the disparities and inequalities of people living with
SCD. This includes helping to address these issues through education, support of
and engagement with the SCD community, as well as charitable giving, such as
through The GBT Foundation we established in 2021. We believe that fostering a
values-driven culture, developing and supporting our people, and creating a more
diverse, equitable and inclusive environment for our employees can help us to
better deliver for SCD patients.

On August 7, 2022, we entered into an Agreement and Plan of Merger, or Merger
Agreement, with Pfizer Inc., a Delaware corporation, or Pfizer, and Ribeye
Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of
Pfizer, or Merger Sub, pursuant to which, and upon the terms and subject to the
conditions described therein, Merger Sub will merge with and into the Company,
with the Company surviving the merger as a wholly owned subsidiary of Pfizer,
which we refer to as the Merger. Under the terms of the Merger Agreement, our
company will be acquired for a total enterprise value of approximately $5.4
billion, including debt and net of cash acquired, or a total equity value of
approximately $5.8 billion. At the closing of the Merger, each issued and
outstanding share of our common stock (other than shares owned by the Company,
any subsidiary of the Company, Pfizer, Merger Sub or any other subsidiary of
Pfizer and other than stockholders of the Company who have validly exercised
their statutory rights of appraisal under the DGCL) will be converted into the
right to receive $68.50 per share, net to the seller in cash, without interest
and subject to any required withholding of taxes. The Merger is expected to
close as early as the fourth quarter of 2022. If the Merger Agreement is
terminated under specified circumstances, we will be required to pay Pfizer a
termination fee of $217 million. The Merger Agreement also provides that, in
connection with the termination of the Merger Agreement under specified
antitrust related circumstances, Pfizer will be required to pay us a "reverse
termination fee" of $326 million.

We are not profitable and have incurred losses and negative cash flows from
operations each year since our inception. We have financed our operations
primarily through sale of equity securities and debt financing, including
several follow-on offerings. In December 2019, we entered into a $150.0 million
term loan agreement, or 2019 Term Loan, with funds managed by Pharmakon Advisors
LP, which are BioPharma Credit PLC, as collateral agent, Biopharma Credit
Investments V (Master) LP, as a lender, and BPCR Limited Partnership, as a
lender, and collectively with Biopharma Credit Investments V (Master) LP, the
Lenders, and drew down proceeds of $72.5 million net of debt issuance costs, and
we drew down the remaining $74.8 million net of debt issuance costs in November
2020. In December 2021, we entered into an Amended and Restated Loan Agreement,
or A&R Term Loan, which amended the 2019 Term Loan to increase the total term
loan by $100.0 million. We received total proceeds, net of the debt issuance
costs of $3.5 million, of an additional $96.5 million. In December 2021, we
issued an aggregate principal amount of $345.0 million of 1.875% convertible
senior notes due 2028, or the 2028 Notes, in a private placement. The aggregate
principal amount on the 2028 Notes sold reflects the full exercise by the
initial purchasers of their option to purchase an additional $45.0 million in
aggregate principal amount of the 2028 Notes. We received total proceeds, net of
debt issuance and offering costs of $11.0 million, of $334.0 million from the
offering. In the six months ended June 30, 2022, we have sold and issued
2,065,358 shares of common stock pursuant to the at-the-market offering program,
or ATM, we entered into in August 2020, with total gross proceeds of $50.0
million before deducting underwriting discounts, commissions, and other offering
expenses payable by us of $1.5 million.

Our net losses were $163.9 million and $144.5 million for the six months ended
June 30, 2022, and 2021. As of June 30, 2022, we had an accumulated deficit of
$1.453 billion. Substantially all of our net losses have resulted from costs
incurred in connection with our research and development programs and from
selling, general and administrative costs associated with our operations. We had
$664.0 million in cash, cash equivalents and investments as of June 30, 2022.


Critical Accounting Policies and Estimates



Our management's discussion and analysis of our financial condition and results
of operations is based on our financial statements, which have been prepared in
accordance with United States generally accepted accounting principles, or U.S.
GAAP. 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 expenses incurred during
the reporting periods. Our estimates are based on our 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.

There have been no material changes to our critical accounting policies and estimates from those described in "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in our Annual Report.

Product sales, net

Product sales consist of sales of Oxbryta, which was approved by the FDA in
November 2019 for the treatment of SCD in adults and children 12 years of age
and older and approved by the FDA in December 2021 for the treatment of SCD in
children ages 4 to less than 12 years. Product sales, net were $71.6 million and
$47.6 million for the three months ended June 30, 2022, and 2021, respectively.
The increase was due to higher volume of sales of $16.5 million driven by
increased patient demand and an increase in distributor inventory of
approximately $7.5 million related to the establishment of an additional
specialty distributor.

Cost of sales



Cost of sales of $1.4 million and $0.7 million for the three months ended June
30, 2022 and 2021, respectively, is related to manufacturing costs incurred
after FDA approval for the cost of Oxbryta sold. The increase was due to higher
volume of sales driven by patient demand. Prior to receiving FDA approval for
Oxbryta in November 2019, we recorded all costs incurred in the manufacture of
Oxbryta as research and development expense. We expect to sell through the
inventory previously expensed to research and development by the end of 2022,
and, accordingly, we expect our costs of product sales of Oxbryta to increase as
a percentage of net sales in future periods as we produce and sell inventory
that reflects the full cost of manufacturing the product.

Research and development

The following table summarizes our research and development expenses incurred during the respective periods (in thousands, except percentages):

Research and development, or R&D, expenses increased by $13.0 million, or 25%,
to $64.8 million for the three months ended June 30, 2022 from $51.8 million for
the three months ended June 30, 2021. The increase was primarily due to an
increase of $9.5 million in external costs related to our inclacumab program due
to an increase in manufacturing activities and ongoing clinical trial
activities, $3.8 million in external costs related to GBT601 due to ongoing
clinical trial activities, and $1.4 million in external costs related to other
preclinical programs. The increase was partially offset by a decrease of $1.7
million in external costs related to Oxbryta due to a decrease in manufacturing
activities for Oxbryta clinical studies. R&D related stock-based compensation
expense was $5.9 million and $4.9 million for the three months ended June 30,
2022, and 2021, respectively.

Selling, general and administrative expenses



Selling, general and administrative, or SG&A, expenses increased by $20.0
million, or 33%, to $81.1 million for the three months ended June 30, 2022 from
$61.1 million for the three months ended June 30, 2021. The increase was
primarily due to an increase of $8.9 million in professional and consulting
services due to increases in medical affairs and commercial related activities
for Oxbryta, an increase of $8.4 million in personnel costs due to higher
headcount, and an increase of $3.9 million in other general and administrative
expenses supporting our growth. The increase was offset by a decrease of $1.2
million in stock-based compensation expenses due to employee turnover. SG&A
related stock-based compensation expense was $13.9 million for the three months
ended June 30, 2022, and $15.1 million for the three months ended June 30, 2021.

Total other expenses, net



Total other expense, net increased by $3.1 million or 88%, to $6.6 million for
the three months ended June 30, 2022 from $3.5 million for the three months
ended June 30, 2021. The increase was primarily due to an increase of $4.4
million in interest expense associated with the A&R Term Loan and the 2028 Notes
issued in December 2021, which was offset by an increase of $1.5 million in
interest income as a result of the higher interest rates on investments.

Product sales, net

Product sales, net were $126.7 million and $86.6 million for the six months ended June 30, 2022, and 2021, respectively. The increase was due to higher volume of sales of $32.6 million driven by increased patient demand and an increase in distributor inventory of approximately $7.5 million related to the establishment of an additional specialty distributor.

Cost of sales



Cost of sales were $2.5 million and $1.3 million for the six months ended June
30, 2022, and 2021, respectively. The increase was due to higher volume of sales
driven by patient demand and increased manufacturing costs of Oxbryta incurred
after FDA approval.

Research and development

The following table summarizes our research and development expenses incurred during the respective periods (in thousands, except percentages):




                                                                                       Change

Total research and development expenses $ 117,608 $ 102,641

    $ 14,967            15 %


Research and development, or R&D, expenses increased by $15.0 million, or 15%,
to $117.6 million for the six months ended June 30, 2022 from $102.6 million for
the six months ended June 30, 2021. The increase was primarily due to an
increase of $9.9 million in external costs related to our inclacumab program due
to an increase in manufacturing activities and ongoing clinical trial
activities, $8.0 million in external costs related to GBT601 due to ongoing
clinical trial activities and $2.1 million in external costs related to other
preclinical programs. The increase was partially offset by a decrease of $5.0
million in external costs related to Oxbryta due to a decrease in manufacturing
activities for Oxbryta clinical studies. R&D related stock-based compensation
expense was $11.5 million and $10.2 million for the six months ended June 30,
2022, and 2021, respectively.

Selling, general and administrative expenses



Selling, general and administrative, or SG&A, expenses increased by $35.6
million, or 30%, to $155.6 million for the six months ended June 30, 2022 from
$120.1 million for the six months ended June 30, 2021. The increase was
primarily due to an increase of $14.8 million in personnel costs due to higher
headcount, an increase of $13.2 million in professional and consulting services
due to increases in medical affairs and commercial related activities for
Oxbryta, and an increase of $10.3 million in other general and administrative
expenses supporting our growth. The increase was offset by a decrease of $2.7
million in stock-based compensation expenses due to employee turnover. SG&A
related stock-based compensation expense was $27.5 million for the six months
ended June 30, 2022, and $30.1 million for the six months ended June 30, 2021.

Total other expenses, net



Total other expense, net increased by $7.6 million or 110%, to $14.5 million for
the six months ended June 30, 2022 from $6.9 million for the six months ended
June 30, 2021. The increase was primarily due to an increase of $8.8 million in
interest expense associated with the A&R Term Loan and the 2028 Notes issued in
December 2021, which was offset by $1.7 million increase in interest income from
our investment portfolio.


Liquidity, Capital Resources and Plan of Operations

We are not profitable and have incurred losses and negative cash flows from operations each year since our inception. We have financed our operations primarily through equity and debt financing. As of June 30, 2022, we had $664.0 million in cash, cash equivalents and investments.



In August 2020, we filed a shelf registration statement on Form S-3, or Shelf
Registration Statement, with the SEC relating to the registration of our common
stock, preferred stock, debt securities, warrants and units or any combination
thereof. Concurrently with the filing of the Shelf Registration Statement, we
entered into a Sales Agreement with SVB Leerink LLC, or Sales Agent, to provide
for the offering, issuance and sale by us of up to an aggregate of $200.0
million of our common stock from time to time in "at-the-market" offerings under
the Shelf Registration Statement, or Sales Agreement. We have agreed to pay to
the Sales Agent cash commissions of up to 3.0% of the gross proceeds from sales
of common stock pursuant to the Sales Agreement. In the six months ended June
30, 2022, we have sold and issued 2,065,358 shares of common stock pursuant to
the Sales Agreement, with total gross proceeds received in 2022 of $50.0 million
before deducting underwriting discounts, commissions, and other offering
expenses payable by us of $1.5 million. As of June 30, 2022, we are authorized
to sell up to a remaining $104.6 million in shares of our common stock under the
Sales Agreement.

In December 2021, we issued an aggregate principal amount of $345.0 million of
1.875% convertible senior notes due 2028 in a private placement, or 2028 Notes.
The aggregate principal amount on the 2028 Notes sold reflects the full exercise
by the initial purchasers of their option to purchase to purchase an additional
$45.0 million in aggregate principal amount of the 2028 Notes. We received total
proceeds, net of debt issuance and offering costs of $11.0 million, of $334.0
million from the offering.

                                       25
--------------------------------------------------------------------------------


In connection with the issuance of the 2028 Notes, we entered into capped call
transactions with certain of the initial purchasers of the 2028 Notes and other
financial institutions, totaling $46.8 million, which we refer to as the Capped
Calls. The Capped Calls cover, subject to customary adjustments, the number of
shares of our common stock that initially underlie the 2028 Notes (or 10,866,983
shares of our common stock). The Capped Calls have an initial strike price and
an initial cap price of $31.7475 per share and $49.80 per share, respectively,
subject to certain adjustments. Conditions that cause adjustments to the initial
strike price of the Capped Calls mirror conditions that result in corresponding
adjustments to the conversion price of the 2028 Notes. The Capped Calls are
expected to offset the potential dilution to our common stock as a result of any
conversion of the 2028 Notes, subject to a cap based on the cap price.

Our primary use of cash is to fund operations. Cash used to fund operations is
impacted by the timing of when we pay these expenses, as reflected in the change
in our outstanding accounts payable and accrued expenses.

We believe that our existing capital resources will be sufficient to fund our
planned operations for at least the next 12 months without giving effect to our
potential acquisition by Pfizer and assuming we remain a standalone entity. We
have based this estimate on assumptions that may prove to be wrong, and we could
utilize our available capital resources sooner than we currently expect. If the
potential acquisition by Pfizer is not completed within the timeframe we
currently expect, we believe we may continue to require additional financing to
commercialize Oxbryta, advance Oxbryta through clinical development, to acquire
and develop other product candidates and to fund operations for the foreseeable
future, and, as such, we may continue to seek funds through equity or debt
financings, collaborative or other arrangements with corporate sources, or
through other sources of financing. Adequate additional funding may not be
available to us on acceptable terms, or at all. In addition, the Merger
Agreement contains restrictions on our issuance of shares of our common stock,
subject to certain exceptions described therein, including pursuant to the Sales
Agreement. Our failure to raise capital as and when needed could have a negative
impact on our financial condition and our ability to pursue our business
strategies. Our future funding requirements will depend on many factors,
including:

the completion of the acquisition by Pfizer within the timeframe we currently expect;

our ability to successfully commercialize Oxbryta, inclacumab, GBT601 and any other product candidates we may identify and develop;


the manufacturing, selling, and marketing costs associated with the
commercialization of Oxbryta and the potential commercialization of inclacumab,
GBT601 and any other product candidates we may identify and develop, including
the cost and timing of establishing or maintaining our sales and marketing
capabilities in any territory(ies);

the amount and timing of sales and other revenues from Oxbryta, inclacumab, GBT601 and any other product candidates we may identify and develop, including the sales price and the availability of adequate third-party reimbursement;

the time and cost necessary to conduct and complete multiple ongoing studies (including our HOPE-KIDS 1 Study, our Phase 3 HOPE-KIDS 2 Study, and other studies;


the time and cost necessary to conduct and complete any additional clinical
studies required to pursue additional regulatory approvals for Oxbryta for SCD,
including our Phase 3 HOPE-KIDS 2 Study (which is intended as our required
confirmatory study to move from our current Subpart H approval to a full
approval of Oxbryta in the United States) and any studies to support potential
label expansions into younger SCD pediatric populations, or any other
post-marketing studies for Oxbryta for SCD;

the progress, data and results of clinical trials of Oxbryta and our product candidates;


the progress, timing, scope and costs of our nonclinical studies, our clinical
trials and other related activities, including our ability to enroll subjects in
a timely manner for our ongoing and future clinical trials of Oxbryta,
inclacumab, GBT601 or any other product candidate that we may identify and
develop;

the costs of obtaining clinical and commercial supplies of Oxbryta, inclacumab, GBT601 and any other product candidates we may identify and develop;


our ability to advance our development programs, including for Oxbryta,
inclacumab, GBT601 and any other potential product candidate programs we may
identify and pursue, the timing and scope of these development activities, and
the availability of approval for any of our other product candidates;


our ability to successfully obtain any additional regulatory approvals from any
regulatory authorities, and the scope of any such regulatory approvals, to
market and sell Oxbryta, inclacumab, GBT601 and any other product candidates we
may identify and develop in any territory(ies);

the cash requirements of any future acquisitions or discovery of product candidates;

the time and cost necessary to respond to technological and market developments;


                                       26
--------------------------------------------------------------------------------


the extent to which we may acquire or in-license other product candidates and
technologies, and the costs and timing associated with any such acquisitions or
in-licenses;

our ability to attract, hire, and retain qualified personnel; and

the costs of maintaining, expanding, and protecting our intellectual property portfolio.



Further, our operating plan may change, and we may need additional funds to meet
operational needs and capital requirements for commercialization, clinical
trials and other research and development expenditures, all subject to whether
the potential acquisition by Pfizer is completed within the timeframe we
currently expect. We currently have no credit facility or committed sources of
capital. Because of the numerous risks and uncertainties associated with the
development and commercialization of Oxbryta and product candidates and ongoing
developments in connection with the COVID-19 pandemic, we are unable to estimate
the amounts of increased capital outlays and operating expenditures associated
with our current and anticipated commercialization, clinical trials and research
and development activities.

The following table summarizes our cash flows for the periods indicated (in
thousands):

Cash flows from operating activities



Cash used in operating activities for the six months ended June 30, 2022 was
$116.2 million, consisting of a net loss of $163.9 million, which was partially
offset by non-cash charges of $39.0 million for stock-based compensation and
$6.2 million for net depreciation and amortization expense, including $1.5
million for non-cash interest expense. The change in our net operating assets
and liabilities was due primarily to a decrease of $6.8 million in accounts
payable due to timing of payments, an increase of $6.8 million in inventories, a
decrease of $2.7 million in operating lease liabilities due to payments made
during the period, a decrease of $2.5 million in accrued compensation, an
increase of $1.0 million in accounts receivable and an increase of $0.4 million
in other non-current assets. The cash outflow was offset by an increase of $14.0
million in accrued liabilities due to timing of receipt of invoices, an increase
of $5.9 million in other non-current liabilities, and a decrease of $3.0 million
in prepaid expenses and other current assets.

Cash used in operating activities for the six months ended June 30, 2021 was
$123.6 million, consisting of a net loss of $144.5 million, which was partially
offset by non-cash charges of $41.2 million for stock-based compensation, $3.0
million for net depreciation and amortization expense, and $0.5 million for
non-cash interest expense. The change in our net operating assets and
liabilities was due primarily to a decrease of $9.7 million in accounts payable
due to timing of payments and receipt of invoices, an increase of $7.7 million
in accrued liabilities due to timing of services performed, a decrease of $7.1
million in prepaid expenses and other current assets, a decrease of $6.8 million
in inventories, a decrease of $4.7 million in accrued compensation primarily due
to the payment of annual employee bonuses, a decrease of $2.3 million in
operating lease liabilities due to payments made during the period, and an
increase in accounts receivable of $2.0 million due to timing of cash receipts
associated with Oxbryta commercial sales.

Cash flows from investing activities

Cash used in investing activities for the six months ended June 30, 2022, was $357.2 million, consisting of purchases of marketable securities of $386.0 million and purchases of property and equipment of $0.7 million, which was offset by maturities of marketable securities of $29.5 million.

Cash provided by investing activities for the six months ended June 30, 2021 was $45.8 million, consisting of maturities of marketable securities of $47.7 million, which was offset by purchases of property and equipment of $1.9 million.

Cash flows from financing activities



Cash provided by financing activities for the six months ended June 30, 2022,
was $50.2 million, primarily from the net proceeds of $48.5 million from the
issuance of common stock pursuant to the ATM and proceeds of $2.8 million from
the issuance of common stock to participants in our employee stock purchase plan
and exercise of stock options, which was offset by $1.1 million in taxes paid
related to net share settlement of equity awards.

Cash provided by financing activities for the six months ended June 30, 2021 was
$2.1 million, primarily from proceeds of $4.1 million from the issuance of
common stock to participants in the employee stock purchase plan and exercise of
stock options, which was partially offset by $2.0 million in taxes paid related
to net share settlement of equity awards.

Contractual Obligations and Other Commitments



Except as noted below, there are no other material changes to our contractual
obligations and commitments outside the ordinary course of business during the
six months ended June 30, 2022, as compared to those disclosed in our Annual
Report on Form 10-K for the year ended December 31, 2021.


In the ordinary course of business, we enter into various firm purchase
commitments related to research development activities and manufacturing
activities. We have entered into agreements with certain vendors for the
provision of goods and services, which include manufacturing services with
contract manufacturing organizations and research and development services with
contract research organizations. These agreements may include certain provisions
for purchase obligations and termination obligations that could require payments
for cancellation of committed purchase obligations or for early termination of
the agreements. The amount of the cancellation or termination payments vary and
are based on the timing of the cancellation or termination and the specific
terms of the agreement. As of June 30, 2022, we have noncancelable contractual
obligations under the terms of a manufacturing agreement of approximately $1.3
million.

See Note 6, Long-term Debt, and Note 7, Convertible Debt, of the notes to our
condensed consolidated financial statements for further details on our future
debt repayment obligations. See Note 8, Commitments and Contingencies, of the
notes to our condensed consolidated financial statements for further details on
our future lease repayment obligation.


As of June 30, 2022, we had no off-balance sheet arrangements as defined in Item 303(a)(4) of Regulation S-K as promulgated by the SEC.

Inflation



Inflation has increased during the periods covered by this Quarterly Report, and
is expected to continue to increase for the near future. Inflationary factors,
such as increases in the cost of our product components, interest rates and
overhead costs may adversely affect our operating results. Although we do not
believe that inflation has had a material impact on our financial position or
results of operations to date, we may experience some effect in the future,
especially if inflation rates continue to rise.
