See "Results of Operations" below for discussion of our results for the periods presented.

Uncertainty Relating to the COVID-19 Pandemic



The COVID-19 pandemic continues to affect economies and business around the
world. Our global revenue sources, mostly in the form of demand interruptions
such as missed patient infusions and delayed treatment starts for new patients,
and our overall business operations were impacted by COVID-19 during the six
months ended June 30, 2022 and 2021, and we anticipate a continued impact on our
financial results in 2022. The extent and duration of such effects remain
uncertain and difficult to predict, particularly as virus variants continue to
spread. We are actively monitoring and managing our response and assessing
actual and potential impacts to our operating results and financial condition,
as well as developments in our business, which could further impact the
developments, trends and expectations described below. See the risk factor
related to the impact of the coronavirus pandemic, "The COVID-19 pandemic could
continue to materially adversely affect our business, results of operations and
financial condition." described in "Risk Factors" in Part II, Item 1A of this
Quarterly Report, for additional details on the impact of the COVID-19 pandemic.

Business Developments



We continued to grow our commercial business and advance our product candidate
pipeline during 2022. We believe that the combination of our internal research
programs, acquisitions and partnerships will allow us to continue to develop and
commercialize innovative therapies for people with serious and life-threatening
rare diseases and medical conditions. Below is a summary of key business
developments:

Continued Emphasis on Research and Development

New Product Launches and Mid-stage Product Life Cycle Expansion Opportunities



?Voxzogo: The global launch of Voxzogo is actively underway, with market access
and reimbursement progressing as anticipated. As of June 30, 2022, we have seen
worldwide increases in the number of children being treated with commercial
Voxzogo and in the number of active markets contributing to Voxzogo sales.

During the quarter, marketing authorization for Voxzogo was approved in both
Japan and Australia, with commercial sales anticipated beginning in the third
quarter of 2022.

During the quarter, we provided a top-line update on the Phase 2 randomized,
double-blind, placebo-controlled Voxzogo study in infants and young children up
to five years of age with achondroplasia at the 2022 Endocrine Society Annual
Meeting (ENDO). We intend to initiate discussions on the favorable results from
the study with regulatory health authorities to discuss next steps regarding
efforts to expand access to Voxzogo treatment for this younger age group.

Also at the ENDO meeting, the investigator-initiated study with Voxzogo in
children with selected genetic causes of short stature, preliminary six-month
results from 12 subjects demonstrated a positive response in all subgroups with
interindividual variability. The 52-week study is ongoing, and is expected to
complete in 2023.

In the quarter, our interventional Phase 2 study with Voxzogo for the treatment
of infants under the age of two who are at risk for foramen magnum compression
completed enrollment. The study is investigating the safety of
                                       23

Voxzogo in infants at risk of requiring surgery to alleviate compression at the
foramen magnum, the opening in the base of the skull through which the spinal
cord passes. The study will also measure a secondary endpoint to evaluate the
effect of Voxzogo on growth of the foramen magnum volume through magnetic
resonance imaging (MRI) scans.

Late-stage Regulatory Portfolio and Mid-stage Product Life Cycle Expansion Opportunities



?Valoctocogene roxaparvovec: In the quarter, the Committee for Medicinal
Products for Human Use (CHMP) adopted a positive opinion recommending
conditional marketing authorization for valoctocogene roxaparvovec, for adults
with severe hemophilia A. A final approval decision, typically consistent with
the CHMP recommendation, is expected from the European Commission in the third
quarter of 2022.

We are targeting a Biologics License Application (BLA) resubmission for valoctocogene roxaparvovec by the end of September 2022. Typically, BLA resubmissions are followed by a six month review procedure. However, we anticipate three additional months of review may be necessary based on the number of data read-outs that will emerge during the procedure.



In July, at the International Society on Thrombosis and Haemostasis 2022
Congress, we reported that durable hemostatic efficacy was maintained over six
years in the ongoing Phase 1/2 study with valoctocogene roxaparvovec in the
6e13vg/kg dose cohort, representing the longest duration of clinical observation
with any gene therapy treatment for adults with severe hemophilia A.

Product expansion opportunities with valoctocogene roxaparvovec are supported by
a number of clinical studies currently underway. The Phase 3b study to evaluate
valoctocogene roxaparvovec with prophylactic corticosteroids has completed
enrollment and is expected to read-out in early 2023. Two additional studies,
one investigating valoctocogene roxaparvovec treatment in those with active or
prior inhibitors, as well as one study investigating valoctocogene roxaparvovec
in people with pre-existing antibodies against AAV5, are actively recruiting at
sites around the world.

Select Earlier-stage Development Portfolio



?BMN 255 for primary hyperoxaluria type 1, a subset of chronic renal disease: We
were recently given permission by the Food and Drug Administration (FDA) to move
forward with the multiple ascending dose portion of the First-in-Human study
with BMN 255. We believe the availability of a potent, orally bioavailable,
small molecule like BMN 255 may be able to significantly reduce disease and
treatment burden in certain people with chronic renal disease.

?BMN 331 gene therapy product candidate for Hereditary Angioedema (HAE): We announced that we have dosed patients in the Phase 1/2 HAERMONY study to evaluate BMN 331, an investigational AAV5-mediated gene therapy for people living with HAE.




Critical Accounting Estimates

In preparing our Condensed Consolidated Financial Statements in accordance with
U.S. GAAP and pursuant to the rules and regulations promulgated by the
Securities and Exchange Commission (the SEC), we make assumptions, judgments and
estimates that can have a significant impact on our net income/loss and affect
the reported amounts of certain assets, liabilities, revenues and expenses, and
related disclosures. On an ongoing basis, we evaluate our estimates and discuss
our critical accounting estimates with the Audit Committee of our Board of
Directors. We base our estimates on historical experience and various other
assumptions that we believe to be reasonable under the circumstances. Actual
results could differ materially from these estimates under different assumptions
or conditions. Historically, our assumptions, judgments and estimates relative
to our critical accounting estimates have not differed materially from actual
results.

The full extent to which the ongoing COVID-19 pandemic could continue to
directly or indirectly impact our business, results of operations and financial
condition, including revenues, expenses, reserves and allowances, manufacturing,
clinical trials and research and development costs will depend on future
developments that continue to remain highly uncertain at this time, particularly
as virus variants continue to spread. As events continue to evolve and
additional information becomes available, our estimates may change materially in
future periods.

There have been no significant changes to our critical accounting estimates during the six months ended June 30, 2022, compared to those disclosed in "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in our Annual Report on Form 10-K for the year ended December 31, 2021, filed with the Securities and Exchange Commission on February 25, 2022.

Net Product Revenues include revenues generated from our approved products. In
the U.S., our commercial products, except for Palynziq and Aldurazyme, are
generally sold to specialty pharmacies or end-users, such as hospitals, which
act as retailers. Palynziq is distributed in the U.S. through certain certified
specialty pharmacies under the Palynziq Risk Evaluation and Mitigation Strategy
(REMS) program, and Aldurazyme is marketed worldwide by Sanofi. Outside the
U.S., our commercial products are sold to authorized distributors or directly to
government purchasers or hospitals, which act as the end-users. In certain
countries, governments place large periodic orders for our products. The timing
of these large government orders can be inconsistent and can create significant
quarter to quarter variation in our revenues.

The increase in Net Product Revenues for the three months ended June 30, 2022 as
compared to the three months ended June 30, 2021 was primarily attributed to the
following:

•Voxzogo: commercial sales due to new patients initiating therapy in Europe and the U.S. following regulatory approvals in the third and fourth quarters of 2021, respectively;

•Aldurazyme: higher product revenues due to timing of product fulfillment to Sanofi; and

•Brineura: higher sales primarily due to new patients initiating therapy in Europe and the U.S.; partially offset by



•Kuvan: lower sales primarily attributed to generic competition as a result of
the loss of exclusivity in the U.S. that occurred in October 2020. We
anticipated and prepared for this loss of exclusivity and the reduction in our
market share, as well as the adverse effect on our revenues and results of
operations. We expect to continue to experience adverse effects on our market
share and revenues in the future due to the loss of exclusivity in the U.S. and
the contracting sapropterin dihydrochloride market.

The increase in Net Product Revenues for the six months ended June 30, 2022 as
compared to the six months ended June 30, 2021 was primarily attributed to the
following:

•Voxzogo: commercial sales due to new patients initiating therapy in Europe and the U.S.;

•Vimizim and Naglazyme: higher product sales primarily attributed to new patients initiating therapy and timing of orders in countries that place large government orders, particularly in Latin America, the Middle East and Europe;

                             Operations (continued)
          (In millions of U.S. dollars, except as otherwise disclosed)

•Brineura: higher sales primarily due to new patients initiating therapy; partially offset by

•Kuvan: lower sales primarily attributed to generic competition as a result of the loss of exclusivity in the U.S. that occurred in October 2020; and

•Aldurazyme: lower product revenues primarily due to timing of product fulfillment to Sanofi.



In certain countries, governments place large periodic orders for our products.
We expect that the timing of these large government orders will continue to be
inconsistent, which may create significant period to period variation in our
revenues. We anticipate the COVID-19 pandemic will have a continued impact on
the remainder of 2022 Net Product Revenues as many of our products are
administered via infusions in a clinic or hospital setting and/or by a
healthcare professional. Although we continue to work with our patient community
and health care providers to find alternative arrangements where necessary, such
as providing infusions at home, the revenue from the doses of our products that
are missed by patients and the lost revenue from delayed treatment starts for
new patients will never be recouped.

See the risk factors "The sale of generic versions of Kuvan by generic
manufacturers has adversely affected and will continue to adversely affect our
revenues and may cause a decline in Kuvan revenues faster than expected" and
"The COVID-19 pandemic could continue to materially adversely affect our
business, results of operations and financial condition" in "Risk Factors"
included in Part II, Item 1A of this Quarterly Report for additional information
on risks we face.

We face exposure to movements in foreign currency exchange rates, primarily the
Euro. We use foreign currency exchange forward contracts to hedge a percentage
of our foreign currency exposure. The following table shows our Net Product

compared to the three and six months ended June 30, 2021 was primarily driven by
weakness relative to the USD associated with the Euro, currencies from certain
Latin American markets, Turkish Lira and Japanese Yen.

Royalty and Other Revenues



Royalty and Other Revenues include royalties earned on net sales of products
sold by third parties, up-front licensing fees, milestones achieved by licensees
or sublicensees and rental income associated with the tenants in our facilities.

                                     Three Months Ended                    Six Months Ended

The increase in Royalty and Other Revenues for the three months ended June 30,
2022 as compared to the three months ended June 30, 2021 was primarily due to
higher royalties earned from net sales of third parties, partially offset by
lower license revenues earned from third parties.

The decrease in Royalty and Other Revenues for the six months ended June 30,
2022 as compared to the six months ended June 30, 2021 was primarily due lower
license revenues earned, partially offset by an increase in royalties earned
from net

          (In millions of U.S. dollars, except as otherwise disclosed)

sales of third parties. The decrease in licenses revenues is primarily attributed to the absence of the license payment earned in the first quarter of 2021 upon a third party's achievement of a regulatory milestone.

We expect to continue to earn royalties from third parties in the future.

Cost of Sales and Gross Margin



Cost of Sales includes raw materials, personnel and facility and other costs
associated with manufacturing our commercial products. These costs include
production materials, production costs at our manufacturing facilities,
third-party manufacturing costs, and internal and external final formulation and
packaging costs. Cost of Sales also includes royalties payable to third parties
based on sales of our products and charges for inventory valuation reserves.

The following table summarizes our Cost of Sales and gross margin:



                           Three Months Ended                         Six Months Ended
                                June 30,                                  June 30,

Total revenues    $ 533.8       $ 501.7       $ 32.1       $ 1,053.2       $ 987.7       $ 65.5
Cost of sales     $ 123.1       $ 127.1       $ (4.0)      $   240.1       $ 247.2       $ (7.1)
Gross margin         76.9  %       74.7  %       2.2  %         77.2  %       75.0  %       2.2  %


Cost of Sales decreased for the three and six months ended June 30, 2022 as
compared to the three and six months ended June 30, 2021 primarily due to lower
inventory reserves and lower manufacturing costs per unit, partially offset by
costs related to increased sales volumes. Gross margin increased for the three
and six months ended June 30, 2022 as compared to the three and six months ended
June 30, 2021 primarily due to lower inventory reserves and the improved per
unit manufacturing costs.

We expect gross margin to range between approximately 75.5% and 77.5% through 2022.



Research and Development

R&D expense includes costs associated with the research and development of product candidates and post-marketing research commitments related to our approved products. R&D expense primarily includes preclinical and clinical studies, personnel and raw materials costs associated with manufacturing clinical product, quality control and assurance, other R&D activities, facilities and regulatory costs.



We manage our R&D expense by identifying the R&D activities we anticipate will
be performed during a given period and then prioritizing efforts based on
scientific data, probability of successful development, market potential,
available human and capital resources and other similar considerations. We
continually review our product pipeline and the development status of product
candidates and, as necessary, reallocate resources among the research and
development portfolio that we believe will best support the future growth of our
business.

We continuously evaluate the recoverability of costs associated with pre-launch
or pre-qualification manufacturing activities, and capitalize the costs incurred
related to those activities if it is determined that recoverability is highly
likely and therefore future revenues are expected. When regulatory approval and
the likelihood of future revenues for a product candidate are less certain, the
related manufacturing costs are expensed as R&D expenses. We had $31.8 million
of manufacturing-related costs for valoctocogene roxaparvovec capitalized as
pre-launch inventory as of June 30, 2022. See Note 3 to our accompanying
Consolidated Financial Statements for additional information regarding our
inventory.

The decrease in R&D expense for the three months ended June 30, 2022 as compared to the three months June 30, 2021 was primarily comprised of the following:



•a decrease in Voxzogo related expenses due to increased capitalization of
manufacturing costs following the regulatory approvals in the second half of
2021; partially offset by

•higher spend in research and early development programs due to increased pre-clinical activities and Investigational New Drug (IND)-enabling studies for planned IND filings.

The increase in R&D expense for the six months ended June 30, 2022 as compared to the six months June 30, 2021 was primarily comprised of the following:

•higher spend in research and early development programs due to increased pre-clinical activities and IND-enabling studies for planned IND filings; and

•an increase in clinical trial activities related to continued development of valoctocogene roxaparvovec; partially offset by



•a decrease in Voxzogo related expenses due to increased capitalization of
manufacturing costs following the regulatory approvals in the second half of
2021.

We expect R&D expense to increase in future periods, primarily due to increased
activities for our research and early development programs while we continue to
develop our later stage programs.

Selling, General and Administrative



Sales and marketing (S&M) expense primarily consisted of employee-related
expenses for our sales group, brand marketing, patient support groups and
pre-commercialization expenses related to our product candidates. General and
administrative (G&A) expense primarily consisted of corporate support and other
administrative expenses, including employee-related expenses.

SG&A expenses consisted of the following:

The increase in S&M expense for the three and six months ended June 30, 2022 as
compared to the three and six months ended June 30, 2021 was primarily a result
of increased activities in support of Voxzogo commercial launch following EU and
U.S. regulatory approvals in the latter half of 2021 and an increase in
valoctocogene roxaparvovec commercial launch preparation activities.

The increase in G&A expense for the three months ended June 30, 2022 as compared
to the three months ended June 30, 2021 was primarily due to increased external
costs related to our strategic initiatives and legal expenses, partially offset
by lower idle plant time related to maintaining our gene therapy manufacturing
facility. The increase in G&A expense for the six months ended June 30, 2022 as
compared to the six months ended June 30, 2021 was primarily due to increased
external costs related to our strategic initiatives, as well as employee-related
and legal expenses.

We expect SG&A expense to increase in future periods as a result of preparing to launch new products and support of our global business as it grows.

Intangible Asset Amortization and Contingent Consideration and Gain on Sale of Nonfinancial Assets, Net



Changes during the periods presented for Intangible Asset Amortization and
Contingent Consideration and Gain on Sale of Nonfinancial Assets, Net were as
follows:

                                                 Three Months Ended                                Six Months Ended

- $ 108.0 $ - $ 108.0

Fair value of contingent consideration - the decrease in the fair value of contingent consideration for the three and six months ended June 30, 2022 as compared to June 30, 2021 was attributable to the changes in the estimated probability of achieving the remaining sales milestones related to our PKU products, as one milestone was achieved in the first quarter of 2022.



Amortization of intangible assets - the expense for the three and six months
ended June 30, 2022 as compared to the three and six months ended June 30, 2021
was relatively flat.

Gain on Sale of Nonfinancial Assets, Net - the increase in the six months ended
June 30, 2022 as compared to the six months ended June 30, 2021 was due to the
sale in the first quarter of 2022 of the Priority Review Voucher (PRV) that we
received in connection with the FDA approval of Voxzogo in 2021. In exchange for
the PRV, we received lump sum payment of $110.0 million, which was recognized as
a gain on the sale of intangible assets, net of broker fees.

Interest Income



We invest our cash equivalents and investments in U.S. government securities and
other high credit quality debt securities in order to limit default and market
risk.

Interest income   $   2.5      $ 4.5      $ (2.0)     $ 4.3      $ 6.9      $ (2.6)


The decrease in Interest Income for the three and six months ended June 30, 2022
compared to the three and six months ended June 30, 2021 was primarily due to
the absence of one-time interest receipts earned in 2021. We expect Interest
Income to be higher over the next 12 months due to anticipated higher interest
rates and yields on our cash equivalents and investments.

Interest Expense

We incur interest expense primarily on our convertible debt. Interest Expense for the periods presented was as follows:



                             Three Months Ended                    Six Months Ended
                                  June 30,                             June 30,

Interest Expense for the three and six months ended June 30, 2022 was flat as
compared to the three and six months ended June 30, 2021. We do not expect
Interest Expense to fluctuate significantly over the next 12 months as the rates
on our convertible debt are fixed. See Note 6 to our accompanying Condensed
Consolidated Financial Statements for additional information regarding our debt.

Other Income (Expense), Net

Other Income (Expense), Net for the periods presented was as follows:



                                     Three Months Ended                  Six Months Ended
                                          June 30,                           June 30,

Other income (expense), net   $  (2.9)     $ 1.8      $ (4.7)     $ (4.1)

$ 1.3 $ (5.4)




The decrease in Other Income (Expense), Net for the three and six months ended
June 30, 2022 compared to the three and six months ended June 30, 2021 was
primarily due to the loss on the fair value of assets held in our nonqualified
deferred compensation plan.

Provision for Income Taxes

The following table summarizes our Provision for Income Taxes:



                                      Three Months Ended                    Six Months Ended

The increase in Provision for Income Taxes for the three and six months ended
June 30, 2022 as compared to the three and six months ended June 30, 2021 was
primarily due to taxes on higher income recognized and projected for 2022, which

Financial Condition, Liquidity and Capital Resources



Our cash, cash equivalents, and investments as of June 30, 2022 and December 31,
2021 were as follows:

                                           June 30, 2022       December 31, 2021       Change

We believe our cash generated from sales of our commercial products, in addition
to our cash, cash equivalents and investments will be sufficient to satisfy our
liquidity requirements for at least the next 12 months. We believe we will meet
longer-term expected future cash requirements and obligations through a
combination of cash flows from operating activities, available cash and
investments balances and available revolving loan balances. We will need to
raise additional funds from equity or debt securities, loans or collaborative
agreements if we are unable to satisfy our liquidity requirements. For example,
we may require additional financing to fund the repayment of our convertible
debt, future milestone payments and our future operations, including the
commercialization of our products and product candidates currently under
development, preclinical studies and clinical trials, and potential licenses and
acquisitions. The timing and mix of our funding alternatives could change
depending on many factors, including how much we elect to spend on our
development programs, potential licenses and acquisitions of complementary
technologies, products and companies or if we settle our convertible debt in
cash. Our ability to raise additional capital may also be adversely impacted by
potential worsening global economic conditions and the recent disruptions to,
and volatility in, financial markets in the U.S. and worldwide resulting from
the ongoing COVID-19 pandemic.

We are mindful that conditions in the current macroeconomic environment could
affect our ability to achieve our goals. We sell our products in countries that
face economic volatility and weakness. Although we have historically collected
receivables from customers in such countries, sustained weakness or further
deterioration of the local economies and currencies and adverse effects of the
impact of the ongoing COVID-19 pandemic may cause customers in those countries
to be unable to pay for our products. We will continue to monitor these
conditions and will attempt to adjust our business processes, as appropriate, to
mitigate macroeconomic risks to our business.

Our cash flows are summarized as follows:



                                                             Six Months Ended June 30,
                                                         2022           2021         Change

Net cash provided by operating activities             $    10.8      $  196.3      $ (185.5)
Net cash provided by (used in) investing activities   $    58.1      $ (191.0)     $  249.1
Net cash used in financing activities                 $   (37.1)     $  

(13.4) $ (23.7)




The decrease in net cash provided by operating activities in the six months
ended June 30, 2022 compared to June 30, 2021 was primarily attributed to the
timing of cash receipts from our customers, the absence of a tax refund from a
Federal carryback claim received in the first quarter of 2021 and higher
employee compensation-related payments.

The increase in net cash provided by investing activities in the six months ended June 30, 2022 compared to June 30, 2021 was primarily attributable to lower net purchases of investments and the $110.0 million proceeds from the sale of PRV in the first quarter of 2022.



The increase in net cash used in financing activities in the six months ended
June 30, 2022 compared to June 30, 2021 was primarily attributed to the payment
to a third party related to our achievement of a PKU sales milestone.

Financing and Credit Facilities



Our $1.1 billion (undiscounted) of total convertible debt as of June 30, 2022
will impact our liquidity due to the semi-annual cash interest payments as well
as the repayment of the principal amount, if not converted. As of June 30, 2022,
our indebtedness consisted of our 0.599% senior subordinated convertible notes
due in 2024 and our 1.25% senior subordinated convertible notes due in 2027,
which, if not converted, will be required to be repaid in cash at maturity in
August 2024 and May 2027, respectively. For additional information related to
our convertible debt see, Note 6 to our accompanying Condensed Consolidated
Financial

Statements and Note 10 - Debt to the Consolidated Financial Statements accompanying our Annual Report on Form 10-K for the year ended December 31, 2021.



In October 2018, we entered into an unsecured revolving credit facility of up to
$200.0 million which includes a letter of credit subfacility and a swingline
loan subfacility. The credit facility is intended to finance ongoing working
capital needs and for other general corporate purposes. In May 2021, we amended
the credit facility agreement, extending the maturity date from October 19, 2021
to May 28, 2024, among other changes. The amended credit facility contains
financial covenants including a maximum leverage ratio and a minimum interest
coverage ratio. As of June 30, 2022, there were no amounts outstanding under the
credit facility and we and certain of our subsidiaries that serve as guarantors
were in compliance with all covenants.

Material Cash Requirements

Funding Commitments



Our investment in our research and early development of product candidates and
continued development of our existing commercial products has a major impact on
our operating performance. R&D expenses for our commercial products and certain
product candidates for the period since inception as of June 30, 2022 were as
follows:


                               Since Program Inception
Valoctocogene roxaparvovec    $                  886.8
Voxzogo                       $                  754.4

BMN 331                       $                   93.7
BMN 255                       $                   30.4
Other approved products       $                2,430.2


We cannot estimate with certainty the cost to complete any of our product
development programs. We may need or elect to increase our spending above our
current long-term plans to be able to achieve our long-term goals. This may
increase our capital requirements, including: costs associated with the
commercialization of our products? additional clinical trials; investments in
the manufacturing of our commercial products? preclinical studies and clinical
trials for our product candidates? potential licenses and other acquisitions of
complementary technologies, products and companies? and general corporate
purposes. Additionally, we cannot precisely estimate the time to complete any of
our product development programs or when we expect to receive net cash inflows
from any of our product development programs. Please see "Risk Factors" included
in Part II, Item 1A of this Quarterly Report on Form 10-Q, for a discussion of
the reasons we are unable to estimate such information.

Purchase Obligations



As of June 30, 2022, we had obligations of approximately $140.8 million, of
which $16.0 million is expected to be paid in 2023, which primarily related to
firm purchase commitments entered into in the normal course of business to
procure active pharmaceutical ingredients, certain inventory-related items and
certain third-party R&D services, production services and facility construction
services.

Contingent Consideration

As of June 30, 2022, we had $30.0 million of acquisition-related contingent
consideration on our Condensed Consolidated Balance Sheet, all of which was Euro
denominated and was short term. For additional information related to our
obligation to Merck Serono related to a 2016 arrangement, see Note 17 to the
Consolidated Financial Statements accompanying our Annual Report on Form 10-K
for the year ended December 31, 2021.

Other Obligations



Our lease, contingent obligations and unrecognized tax benefits as of June 30,
2022 have not materially changed from those discussed in "Financial Condition,
Liquidity and Capital Resources" in Part II, Item 7 of our Annual Report on Form
10-K for the year ended December 31, 2021.
