operations should be read together with Item 6, "Selected Financial Data" and
the consolidated financial statements and the related notes included in Item 8
of this Annual Report on Form 10-K. This discussion contains forward-looking
statements related to future events and our future financial performance that
are based on current expectations and subject to risks and uncertainties. Our
actual results may differ materially from those anticipated in these
forward-looking statements as a result of many factors, including those set
forth in Part I-Item 1A. "Risk Factors" and "Cautionary Note Regarding Forward
Looking Statements." included in this Annual Report on Form 10-K.

Overview

Our Business



We are an established leader and fully integrated provider committed to
innovative imaging diagnostics, targeted therapeutics, and artificial
intelligence solutions to Find, Fight and Follow serious medical conditions. We
classify our products in three revenue categories: precision diagnostics,
radiopharmaceutical oncology, and strategic partnerships and other revenue. Our
leading precision diagnostic products assist HCPs Find and Follow diseases in
non-oncologic conditions. Our radiopharmaceutical oncology diagnostics and
therapeutics help HCPs Find, Fight and Follow cancer. Our strategic partnerships
and other revenue category focuses on facilitating precision medicine through
the use of biomarkers, digital solutions and radiotherapeutic platforms, and
also includes our license of RELISTOR to Bausch.

Our commercial products are used by cardiologists, internal medicine physicians,
nuclear medicine physicians, oncologists, radiologists, sonographers,
technologists and urologists working in a variety of clinical settings. We
believe that our diagnostic products provide improved diagnostic information
that enables HCPs to better detect and characterize, or rule out, disease, with
the potential to achieve better patient outcomes, reduce patient risk and limit
overall costs for payors and throughout the healthcare system.

We produce and market our products throughout the U.S., selling primarily to
clinics, group practices, hospitals, integrated delivery networks and
radiopharmacies. We sell our products outside the U.S. through a combination of
direct distribution in Canada and third party distribution relationships in
Europe, Canada, Australia, Asia-Pacific, Central America and South America.

Our headquarters are located in North Billerica, MA, with additional offices in Somerset, NJ; Montreal, Canada and Lund, Sweden.



In the first quarter of 2021, we completed the evaluation of our operating and
reporting structure, including the impact on our business of the acquisition of
Progenics, and the sale of our Puerto Rico subsidiary, which resulted in a
change in our operating segments to one reportable business segment.

Key Factors Affecting Our Results

Our 2021 financial performance reflects full year results of the Progenics business, whereas the year ended December 31, 2020 only incorporates results since the June 19, 2020 closing date of the Progenics Acquisition.

Our business and financial performance have been, and continue to be, affected by the following:

PYLARIFY Approval and Commercial Launch



On May 27, 2021, we announced that the U.S. Food and Drug Administration ("FDA")
had approved PYLARIFY, an F 18-labeled PET imaging agent targeting
prostate-specific membrane antigen ("PSMA"). PYLARIFY is a product in our
radiopharmaceutical oncology product category. We commercially launched PYLARIFY
in the U.S. in June 2021.

PYLARIFY is a radioactive diagnostic agent indicated for PET imaging of
PSMA-positive lesions in men with prostate cancer with suspected metastasis who
are candidates for initial definitive therapy and with suspected recurrence
based on elevated serum prostate-specific antigen ("PSA") levels. PYLARIFY works
by binding to PSMA, a protein that is overexpressed on the surface of more than
90% of primary and metastatic prostate cancer cells. PYLARIFY works with PET/CT
technology to produce a combined PET/CT scan that enables the reader of the
PET/CT scan to detect and locate the disease.

According to the American Cancer Society, prostate cancer is the second most
common cancer in American men -- one in eight American men will be diagnosed
with prostate cancer in their lifetimes and over 3.1 million American men are
living with prostate cancer today. Based on estimates from third party sources
regarding the incidence of prostate cancer in men in the U.S., we believe the
market potential for PSMA PET imaging agents could be up to 220,000 annual
scans, comprised of 90,000 scans for patients with intermediate, unfavorable or
high/very high risk of suspected metastases of prostate cancer and 130,000 scans
for patients with

                                       60

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

suspected recurrence of prostate cancer. Because we are in the process of launching this imaging agent, we can give no assurance as to how clinical practice may evolve or what our ultimate market penetration may be.



The approval of PYLARIFY was based on data from two Company-sponsored pivotal
studies ("OSPREY" and "CONDOR") designed to establish the safety and diagnostic
performance of PYLARIFY across the prostate cancer disease continuum. Results
from OSPREY (Cohort A) demonstrated improvement in specificity and positive
predictive value of PYLARIFY PET imaging over conventional imaging in men at
risk for metastatic prostate cancer prior to initial definitive therapy. CONDOR
studied men with biochemical recurrent prostate cancer. In patients with
biochemical recurrent prostate cancer and non-informative baseline imaging,
PYLARIFY demonstrated high correct localization and detection rates, including
in patients with early recurrent disease with low, but rising, PSA blood levels
(median PSA 0.8 ng/mL).

Upon commercial launch in June 2021, PYLARIFY was immediately available in
select parts of the U.S. Over the course of the remainder of 2021, PYLARIFY
availability expanded into additional regions and is now broadly available
nationwide. We continue to expand our geographic coverage, customer contracting
and market access coverage to serve our customers and the U.S. prostate cancer
community.

The commercial launch of PYLARIFY is complex and expensive. During 2021, we
hired additional employees to assist us with the commercialization of PYLARIFY,
including in sales, marketing, reimbursement, quality and medical affairs. To
manufacture PYLARIFY, we assembled and qualified a nationwide network of PMFs
with radioisotope-producing cyclotrons that make F 18, which has a 110-minute
half-life, so PYLARIFY is manufactured and distributed rapidly to end-users.
After being made on a cyclotron at a PMF, the F 18 is then combined with certain
chemical ingredients in specially designed chemistry synthesis boxes to
manufacture PYLARIFY. The finished PYLARIFY is then quality control tested and
transferred to a radiopharmacist who prepares and dispenses patient-specific
doses of the final product. Because each of the PMFs manufacturing these
products is deemed by the FDA to be a separate manufacturing site, each has to
be separately approved by the FDA. Although PYLARIFY is now broadly available
nationwide and we continue to qualify additional PMFs, we can give no assurance
that the FDA will continue to approve PMFs in accordance with our planned
roll-out schedule. If FDA approval of manufacturing sites is delayed or
withdrawn, our future business, results of operations, financial condition and
cash flows could be adversely affected.

In addition to the network of PMFs, we have also been working with academic
medical centers in the U.S. that have radioisotope-producing cyclotrons and
which have expressed an interest in manufacturing PYLARIFY. Under this
initiative, we would enter into a fee-for-service arrangement under which the
academic medical center's PMF would manufacture and supply batches of PYLARIFY,
and its radiopharmacy would prepare patient-ready unit doses, in each case for
and on behalf of us. We would then sell those unit doses to the academic medical
center's hospitals and clinics, and in some instances, to additional customers
in the academic medical center's geographic area, in each case, under separate
purchase agreements. The academic medical center's PMF's ability to manufacture
and supply batches of PYLARIFY will be subject to FDA approval, and we can give
no assurance that the FDA will approve such PMFs in accordance with our planned
roll-out schedule.

Our commercial launch also required obtaining adequate coding, coverage and
payment for PYLARIFY, including not only coverage from Medicare, Medicaid and
other government payors, as well as private payors, but also appropriate payment
levels, to adequately cover our customers' costs of using PYLARIFY in PET/CT
imaging procedures. We received notification that our HCPCS code, which enables
streamlined billing, went into effect as of January 1, 2022. In addition,
effective January 1, 2022, the CMS granted Transitional Pass-Through Payment
Status in the hospital outpatient setting ("TPT Status") for PYLARIFY, enabling
traditional Medicare to provide an incremental payment for PET/CT scans
performed with PYLARIFY in that setting. TPT Status for PYLARIFY is expected to
expire December 31, 2024. After TPT Status expires, under current Medicare
rules, PYLARIFY, similar to other diagnostic radiopharmaceuticals, would not be
separately reimbursed in the hospital outpatient setting but rather would be
included as part of the facility fee a hospital otherwise receives for a PET/CT
imaging procedure, and the facility fee does not always cover the cost of a drug
used in the procedure. We can give no assurance that any CMS reimbursement in
the hospital outpatient setting that follows the expiration of TPT Status will
be adequate to cover the cost of PYLARIFY used in a PET/CT imaging procedure.

We actively pursue patents in connection with PYLARIFY, both in the U.S. and
internationally. In the U.S. for PYLARIFY, we have four Orange Book-listed
patents, including composition of matter patents, which expire in 2030 and 2037.
Outside of the U.S., we are currently pursuing additional PYLARIFY patents to
obtain similar patent protection as in the U.S.

PYLARIFY AI Clearance and Use



During 2021, we also announced that our subsidiary, EXINI, was granted 510(k)
clearance by the FDA in the U.S. and received CE marking in Europe for aPROMISE.
We commercially launched aPROMISE under the name PYLARIFY AI in the U.S. in
November 2021.

                                       61

PYLARIFY AI is artificial intelligence medical device software developed to
assist with the reading and quantification of PYLARIFY scans. The technology
automatically analyzes a PSMA PET/CT image to segment anatomical regions - 51
bones and 12 soft tissue organs. This image segmentation enables automated
localization, detection and quantification of potential PSMA-avid lesions in a
PSMA PET/CT image, which is then incorporated into a standardized report for
physicians.

Anticipated Continued Growth of DEFINITY and Expansion of Our Ultrasound Microbubble Franchise



We believe the market opportunity for our ultrasound microbubble enhancing
agent, DEFINITY, continues to be significant. DEFINITY has been our fastest
growing and highest margin commercial product. We anticipate DEFINITY sales will
continue to grow in the future. As we continue to educate the physician and
healthcare provider community about the benefits and risks of DEFINITY, we
believe we will be able to continue to grow the appropriate use of DEFINITY in
suboptimal echocardiograms. In a U.S. market with three echocardiography
ultrasound enhancing agents approved by the FDA, we estimate that DEFINITY had
over 80% of the market as of December 31, 2021.

As we continue to pursue expanding our microbubble franchise, our activities include:



•Patents - We continue to actively pursue additional patents in connection with
DEFINITY and DEFINITY RT, both in the U.S. and internationally. In the U.S. for
DEFINITY, we have four Orange Book-listed method of use patents, one of which
expires in 2035 and three of which expire in 2037, as well as additional
manufacturing patents that are not Orange Book-listed expiring in 2023 and 2037.
In the U.S. for DEFINITY RT, we have five Orange Book-listed patents, including
a composition of matter patent which expires in 2035. Outside of the U.S., we
are currently pursuing additional DEFINITY and DEFINITY RT patents to obtain
similar patent protection as in the U.S. The Orange Book-listed patents include
a patent on the use of VIALMIX RFID which expires in 2037; we have submitted
additional VIALMIX RFID patent applications in major markets throughout the
world.

Hatch-Waxman Act - Even though our longest duration Orange Book-listed DEFINITY
patent extends until March 2037, because our Orange Book-listed composition of
matter patent expired in June 2019, we may face generic DEFINITY challengers in
the near to intermediate term. Under the Hatch-Waxman Act, the FDA can approve
Abbreviated New Drug Applications ("ANDAs") for generic versions of drugs if the
ANDA applicant demonstrates, among other things, that (i) its generic candidate
is the same as the innovator product by establishing bioequivalence and
providing relevant chemistry, manufacturing and product data, and (ii) either
the marketing of that generic candidate does not infringe the Orange Book-listed
patent(s) or the Orange Book-listed patent(s) is invalid. Similarly, the FDA can
approve a Section 505(b)(2) NDA from an applicant that relies on some of the
information required for marketing approval to come from studies which the
applicant does not own or have a legal right of reference. With respect to the
Orange Book-listed patent(s) covering an innovator product, the ANDA applicant
or the Section 505(b)(2) applicant (if relying on studies related to the
innovator product) (together, the "Applicant") must give a notice (a "Notice")
to the innovator of its certification that its generic candidate will not
infringe the innovator's Orange Book-listed patent(s) or that the Orange
Book-listed patent(s) is invalid. The innovator can then file suit against the
Applicant within 45 days of receiving the Notice, and FDA approval to
commercialize the generic candidate will be stayed (that is, delayed) for up to
30 months (measured from the date on which a Notice is received) while the
patent dispute between the innovator and the Applicant is resolved in court. The
30-month stay could potentially expire sooner if the courts determine that no
infringement had occurred or that the challenged Orange Book-listed patent is
invalid or if the parties otherwise settle their dispute.

As of the date of filing of this Annual Report on Form 10-K, we have not
received any Notice from an Applicant. If we were to (i) receive any such Notice
in the future, (ii) bring a patent infringement suit against the Applicant
within 45 days of receiving that Notice, and (iii) successfully obtain the full
30-month stay, then the Applicant would be precluded from commercializing a
generic version of DEFINITY prior to the expiration of that 30-month stay period
and, potentially, thereafter, depending on how the patent dispute is resolved.
Solely by way of example and not based on any knowledge we currently have, if we
received a Notice from an Applicant in March 2022 and the full 30-month stay
were obtained, then the Applicant would be precluded from commercialization
until at least September 2024. If we received a Notice some number of months in
the future and the full 30-month stay were obtained, the commercialization date
would roll forward in the future by the same number of months. In the event a
505(b)(2) applicant does not rely on studies related to the innovator product,
the 30-month stay would not apply, but additional clinical studies may be
required.

•DEFINITY RT - DEFINITY RT became commercially available in the fourth quarter
of 2021. A modified formulation of DEFINITY that allows both storage and
shipment at room temperature, DEFINITY RT provides clinicians an additional
choice and allows for greater utility of this formulation in broader clinical
settings. Given its physical characteristics, we believe DEFINITY RT is also
well-suited for inclusion in kits requiring microbubbles for other indications
and applications (including in kits developed by third parties of the type
described in the paragraph entitled Microbubble below).

•VIALMIX RFID - VIALMIX RFID, our next-generation activation device designed
specifically for both DEFINITY and DEFINITY RT, became commercially available in
the fourth quarter of 2021. The activation rate and time are controlled by
VIALMIX RFID through the use of radio-frequency identification technology
("RFID") to ensure reproducible activation of

                                       62

DEFINITY and DEFINITY RT. The RFID tag, which is affixed to the vial label, enables the DEFINITY or DEFINITY RT vial to be appropriately activated with the VIALMIX RFID activation device.

Global Mo-99 Supply



We currently have Mo-99 supply agreements with Institute for Radioelements
("IRE"), running through December 31, 2022, with auto-renewal provisions and
terminable upon notice of non-renewal, and with NTP Radioisotopes ("NTP"),
acting for itself and on behalf of its subcontractor, the Australian Nuclear
Science and Technology Organisation ("ANSTO"), running through March 31, 2022,
and for which we are currently negotiating an extension. We also have a Xenon
supply agreement with IRE which runs through December 31, 2023, with
auto-renewal provisions and terminable upon notice of non-renewal.

Although we have a globally diverse Mo-99 supply with IRE in Belgium, NTP in
South Africa, and ANSTO in Australia, we still face supplier and logistical
challenges in our Mo-99 supply chain. The NTP processing facility had periodic
outages in 2017, 2018 and 2019. When NTP was not producing, we relied on Mo-99
supply from both IRE and ANSTO to limit the impact of the NTP outages. In 2019
and 2020, ANSTO experienced multiple facility issues that resulted in ANSTO
outages and volume limitations, during which time we relied on IRE and NTP to
limit the impact of those outages and limitations. Because of the COVID-19
pandemic, we experienced challenges receiving regularly scheduled orders of
Mo-99 from our global suppliers, particularly in the second quarter of 2020. We
continue to manage these various supply chain challenges, but depending on
reactor and processor schedules and operations, at times we have not been able
to fill some or all of the demand for our TechneLite generators on certain
manufacturing days. A prolonged disruption of service from one of our three
Mo-99 processing sites or one of their main Mo-99-producing reactors could have
a substantial negative effect on our business, results of operations, financial
condition and cash flows.

To augment our current supply of Mo-99, we have a strategic arrangement with
SHINE Medical Technologies LLC ("SHINE") for the future supply of Mo-99. Under
the terms of the supply agreement, entered into in November 2014, SHINE will
provide Mo-99 produced using its proprietary LEU-solution technology for use in
our TechneLite generators once SHINE's facility becomes operational and receives
all necessary regulatory approvals, which SHINE now estimates will occur in
2023. The term of this arrangement provides for three years of supply of Mo-99.
However, we cannot assure you that SHINE will be able to produce commercial
quantities of Mo-99 for our business, or that SHINE together with our current
suppliers will be able to deliver a sufficient quantity of Mo-99 to meet our
needs.

Inventory Supply

We obtain a substantial portion of our imaging agents from a third party
supplier. JHS is currently a significant supplier of DEFINITY and our sole
source manufacturer of NEUROLITE, Cardiolite and evacuation vials, the latter
being an ancillary component for our TechneLite generators. In addition to JHS,
we rely on SBL as our sole source manufacturer of DEFINITY RT. Our new
manufacturing agreement with JHS relating to DEFINITY, NEUROLITE and Cardiolite
expires in December 2027.

In 2021, we have constructed a specialized in-house manufacturing facility at
our North Billerica campus for purposes of producing DEFINITY and, potentially,
other sterile vial products. On February 22, 2022, we received FDA approval of
our sNDA, authorizing commercial manufacturing of DEFINITY at our new facility.
DEFINITY manufactured at this facility became commercially available on February
23, 2022. We believe this investment will allow us to better manage DEFINITY
manufacturing and inventory, reduce our costs in a potentially more price
competitive environment, and provide us with supply chain redundancy.

Radiopharmaceuticals are decaying radioisotopes with half-lives ranging from a
few hours to several days. These products cannot be kept in inventory because of
their limited shelf lives and are subject to just-in-time manufacturing,
processing and distribution, which takes place at our facilities in North
Billerica, Massachusetts and Somerset, New Jersey.

COVID-19 Pandemic



The global COVID-19 pandemic has had, and may continue to have, a material
impact on our business. Towards the end of the first quarter of 2020 we began to
experience, and through the date of this filing we are continuing to experience,
impacts to our business and operations related to the COVID-19 pandemic,
including the impact of hospital staffing challenges, vaccination mandates,
employee absences due to illness, and a decline in the volume of certain
procedures and treatments using our products.

Although some of the restrictions, including stay-at-home mandates, imposed in
response to the COVID-19 pandemic have been lifted in much of the U.S., and
there has been a rapid rollout and development of multiple vaccines and
boosters, the resurgence of COVID-19 infections continued to impact certain
aspects of our business during the fourth quarter of 2021. For example, we
believe sales of DEFINITY were impacted by hospital nursing and sonographer
shortages, and sales of AZEDRA were impacted by treatment capacity constraints
in hospitals, treatment deferrals and cancellations by patients, and access
restrictions by hospitals. In addition, there has been a substantial reduction
in pulmonary ventilation studies in which our product, Xenon, is used because of
institutional concerns and professional society guidelines relating to the
possible spread of COVID-19 to technicians and other patients, because

                                       63

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

Table of Contents




Xenon is both inhaled and exhaled by the patient. Our Xenon sales through the
fourth quarter of 2021 continued to be at reduced levels, we expect these
reduced levels to continue for at least as long as COVID-19 precautions remain
in place, and we can give no assurance that Xenon sales will return to historic
levels.

The pandemic could still have a future negative impact on our business,
particularly if there are additional resurgences as a result of mutations or
other variations to the virus that further increase its communicability or its
impact on certain populations, geographic regions and the healthcare system,
including elective procedures and hospital access.

Research and Development Expenses

To remain a leader in the marketplace, we have historically made and will continue to make substantial investments in new product development and lifecycle management for existing products.

•For PYLARIFY, our development of PYLARIFY resulted in approval by the FDA in May 2021.



•For 1095, the ARROW Phase 2 study in mCRPC patients was paused to minimize risk
to subjects and healthcare providers during the pandemic, and new enrollment in
that study restarted in October 2020. In the fourth quarter of 2021, we
completed an interim analysis of the ARROW Phase 2 study and are continuing that
study without modifications. We currently expect to complete enrollment in the
ARROW Phase 2 study later in 2022.

•For LMI 1195, we have commenced a Phase 3 clinical trial for the use of LMI
1195 for the diagnosis and management of neuroblastoma tumors in pediatric and
adult populations. We expect to initiate approximately 20 clinical sites in the
U.S. to enroll approximately 100 patients with known or suspected neuroblastoma.

•We are also exploring additional lifecycle management opportunities for some of our current products, including AZEDRA.



Our investments in these additional clinical activities and lifecycle management
opportunities will increase our operating expenses and impact our results of
operations and cash flow, and we can give no assurances as to whether any of
these clinical development candidates or lifecycle management opportunities will
be successful.

Strategic Partnerships and Other Revenue



We continue to seek ways to further expand our portfolio of products and product
candidates and how best to optimize the value of our current assets, evaluating
a number of different opportunities to collaborate with others or to acquire or
in-license additional products, product candidates, businesses and technologies
to drive our future growth.

Oncology

As we continue to pursue expanding our strategic partnerships, our Pharma Services activities and strategic partnerships in oncology include:



•Prostate Cancer - We collaborate with pharmaceutical companies developing
therapies and diagnostics in prostate cancer. In January 2022, we announced a
collaboration with the Prostate Cancer Clinical Trial Consortium ("PCCTC"), a
premier multicenter clinical research organization that specializes in prostate
cancer research. The intent of the strategic collaboration is to integrate our
AI platform into PCCTC studies to advance the development and validation of
novel AI-enabled biomarkers. In September 2021, we entered into a development
and commercialization collaboration with RefleXion Medical, Inc. to evaluate the
use of piflufolastat F 18 to enable real-time therapeutic guidance of
biology-guided radiotherapy in prostate cancer using the RefleXion X1TM
platform. Prior to 2021, we had also entered into several other agreements,
including ones with Bayer, POINT Biopharma and Regeneron, under which we supply
piflufolastat F 18 in connection with their clinical studies, and Curium, under
which we licensed exclusive rights to Curium to develop and commercialize
piflufolastat F 18 in Europe.

•Immuno-Oncology - In May 2019, we entered into a strategic collaboration and
license agreement with NanoMab, a privately-held biopharmaceutical company
focused on the development of next generation radiopharmaceuticals for cancer
precision medicine.

•Pan-Oncology - In March 2021, we acquired from Ratio Therapeutics LLC
(previously Noria Therapeutics, Inc.) exclusive, worldwide rights to NTI-1309,
an innovative imaging biomarker that targets fibroblast activation protein, an
emerging target with broad potential imaging applicability and use in oncology.
Upon further clinical development, we will assess options to bring NTI-1309 to
market as a diagnostic or potentially a therapeutic product.

Microbubble Franchise

In addition, as described above, we continue to expand our microbubble franchise. In April 2021, we announced a strategic collaboration with Allegheny Health Network ("AHN"), which will use our microbubbles in combination with AHN's ultrasound-


                                       64

assisted non-viral gene transfer technology for the development of a proposed
treatment of xerostomia. Xerostomia is a lack of saliva production leading to
dry mouth and has a variety of causes, including radiotherapy and chemotherapy,
the chronic use of drugs and rheumatic and dysmetabolic diseases. Prior to 2021,
we entered into microbubble collaborations with the following parties: (i)
Cerevast Medical, Inc. ("Cerevast"), in which our microbubbles will be used in
connection with Cerevast's ocular ultrasound device to improve blood flow in
occluded retinal veins in the eye; (ii) CarThera SAS, for the use of our
microbubbles in combination with SonoCloud, a proprietary implantable device in
development for the treatment of recurrent glioblastoma; and (iii) Insightec
Ltd. ("Insightec"), which will use our microbubbles in connection with the
development of Insightec's transcranial guided focused ultrasound device for the
treatment of glioblastoma as well as other neurodegenerative conditions.

Generally, our costs in connection with the strategic partnerships relate to the
supply of drug and other ancillary expenses and the benefits can include
possible supply, milestone and royalty payments, additional intellectual
property rights and strategic relationships. We can give no assurance as to if
or when or if any of these collaborations and other new initiatives will be
successful or accretive to earnings.

Comparison of the Periods Ended December 31, 2021 and 2020

Revenues



We classify our revenues into three product categories: precision diagnostics,
radiopharmaceutical oncology, and strategic partnerships and other revenue.
Precision diagnostics includes DEFINITY, TechneLite and other imaging diagnostic
products. Radiopharmaceutical oncology consists primarily of PYLARIFY and
AZEDRA. Strategic partnerships and other revenue includes partnerships that
focus on facilitating precision medicine through the use of biomarkers, digital
solutions and radiotherapeutic platforms, and on our other products, such as
RELISTOR.

Revenues are summarized by product category on a net basis as follows:

________________________________

(1)We reclassified aggregate rebates and allowances of $19.1 million and $16.6 million for the years ended December 31, 2020 and 2019, respectively, which included $17.5 million and $15.1 million for DEFINITY, $1.3 million and $1.1 million for TechneLite and $0.3 million for other precision diagnostics.



The increase in revenues for the year ended December 31, 2021, as compared to
the prior year period, is primarily driven by the commercial launch of PYLARIFY,
as well as increases in DEFINITY and TechneLite volume period over period as a
result of the COVID-19 pandemic in the prior year, as well as the addition of
the Progenics product portfolio, including RELISTOR. These increases are
partially offset by continued COVID-19 related reduced volumes in our sales of
Xenon throughout 2021 and the divestiture of our Puerto Rico business during the
first quarter of 2021.

Rebates and Allowances

Estimates for rebates and allowances represent our estimated obligations under
contractual arrangements with third parties. Rebate accruals and allowances are
recorded in the same period the related revenue is recognized, resulting in a
reduction to revenue and the establishment of a liability which is included in
accrued expenses. These rebates and allowances result from performance-based
offers that are primarily based on attaining contractually specified sales
volumes and growth, Medicaid rebate programs for our products, administrative
fees of group purchasing organizations and certain distributor related
commissions. The calculation of the accrual for these rebates and allowances is
based on an estimate of the third party's buying patterns and the resulting
applicable contractual rebate to be earned over a contractual period.

An analysis of the amount of, and change in, reserves is summarized as follows:

Gross Profit

The increase in gross profit for the year ended December 31, 2021, as compared
to the prior year period, is primarily due to an increase in volume of DEFINITY
sales and the commercial launch of PYLARIFY in 2021, as well as an asset
impairment loss of $7.3 million on other nuclear products that occurred in the
prior year. These increases were offset, in part, by lower sales of our Xenon
and increased radioisotope transportation costs, both due to COVID-19, as well
as amortization expense of $2.7 million related to assets acquired in the
Progenics Acquisition and accelerated recognition of asset retirement
obligations of $5.4 million due to a change in useful life estimate.

Sales and Marketing



Sales and marketing expenses consist primarily of salaries and other related
costs for personnel in field sales, marketing and customer service functions.
Other costs in sales and marketing expenses include the development and
preparation of advertising and promotional material, professional services,
market research and sales meetings.

Sales and marketing expenses increased $27.5 million for the year ended December
31, 2021, as compared to the prior year period. This was primarily driven by
preparation activities for the launch of PYLARIFY (including the hiring of
additional employees) in 2021 and a full year of sales and marketing expenses
related to AZEDRA, as well as the reduced level of marketing and promotional
programs during the prior year period as a result of the COVID-19 pandemic.

General and Administrative



General and administrative expenses consist of salaries and other related costs
for personnel in executive, finance, legal, information technology and human
resource functions. Other costs included in general and administrative expenses
are professional fees for information technology services, external legal fees,
consulting and accounting services as well as bad debt expense, certain facility
and insurance costs, including director and officer liability insurance.

General and administrative expenses increased $81.1 million for the year ended
December 31, 2021 compared to the prior year period. This was primarily driven
by the $72.4 million fair value adjustment to the contingent asset and
liabilities, including the CVRs (an increase of $74.4 million from the prior
year period), $9.5 million impairment charge related to the sublease of office
space in the World Trade Center, and higher headcount related costs following
the Progenics Acquisition, offset by acquisition-related costs associated with
the Progenics Acquisition in the prior year and synergy capture in the current
year.

Research and Development

Research and development expenses relate primarily to the development of new products to add to our portfolio and costs related to our medical affairs, medical information and regulatory functions.



Research and development expenses increased $12.2 million for the year ended
December 31, 2021 as compared to the prior year period. This was primarily
driven by additional research and development expenses related to 1095 and
preparation activities for the launch of PYLARIFY, as well as higher
employee-related costs in 2021 (including the hiring of additional employees) as
compared to the prior year. The increase in research and development expenses
during 2021 was offset by the filing fee paid in the prior year period related
to the PYLARIFY New Drug Application.

Gain on Sale of Assets

We sold 100% of the stock of our Puerto Rico radiopharmacy subsidiary, resulting in a pre-tax book gain of $15.3 million for the year ended December 31, 2021.

Interest Expense



Interest expense for the year ended December 31, 2021 decreased $1.7 million as
compared to the prior year period due to lower interest rates on our long-term
debt together with reduced debt as a result of the voluntary repayment of the
outstanding principal on our $50.0 million loan agreement (the "Royalty-Backed
Loan") between Progenics, through a wholly-owned subsidiary MNTX Royalties Sub
LLC ("MNTX Royalties"), and a fund managed by HealthCare Royalty Partners III,
L.P. on March 31, 2021.

Gain on Extinguishment of Debt

During the year ended December 31, 2021, we realized a $0.9 million gain on extinguishment of debt related to the voluntary repayment of the outstanding principal on the Royalty-Backed Loan on March 31, 2021.

Other (Income) Loss

Other (income) loss changed by $9.5 million for the year ended December 31, 2021
as compared to the prior year, due to the reduction of indemnified receivables
related to the release of uncertain tax positions.

Income Tax (Benefit) Expense



The income tax benefit of $3.8 million for the year ended December 31, 2021 was
primarily due to incurred losses before tax, the release of a portion of our
uncertain tax positions, stock compensation deductions, and tax credits, offset
by non-deductible expenses related to the changes in fair value of contingent
assets and liabilities, the accrual of interest associated with uncertain tax
positions, and the impact of an increased effective state tax rate on our ending
net deferred tax assets. In accordance with our accounting policy, the change in
the tax liabilities, penalties and interest associated with our uncertain tax
positions (net of any offsetting federal or state benefit) is recognized within
income tax benefit. The majority of our uncertain tax positions are indemnified
liabilities, in accordance with the Stock and Asset Purchase Agreement entered
into with Bristol-Myers ('BMS') in 2008. Changes in the liability result in
offsetting changes in the indemnification receivable. Changes in the
indemnification receivable are recognized within other loss (income) in the
consolidated statement of operations. Assuming that the receivable from BMS
continues to be considered recoverable by us, there will be no effect on net
income and no net cash outflows related to these liabilities. Refer to Note 5,
Income Taxes.

The income tax expense of $2.0 million for the year ended December 31, 2020 was
primarily due to the accrual of interest associated with uncertain tax positions
and the impact of non-deductible acquisition costs, offset by the tax benefits
on losses generated in the period, the recognition of the deferred tax asset on
held for sale assets, and tax credits.

We regularly assess our ability to realize our deferred tax assets. Assessing
the realizability of deferred tax assets requires management judgment. In
determining whether our deferred tax assets are more-likely-than-not realizable,
we evaluate all available positive and negative evidence, and weigh the
objective evidence and expected impact. We continue to record a valuation
allowance against certain of our foreign net deferred tax assets and a small
component of our domestic deferred tax assets.

Our effective tax rate for each reporting period is presented as follows:


                                                   Year Ended
                                                  December 31,

                     Effective tax rate     5.0%             (17.4)%


Our effective tax rate in fiscal 2021 differs from the U.S. statutory rate of
21% principally due to the impact of non-deductible expenses related to changes
in fair value of contingent assets and liabilities, releases of uncertain tax
position liabilities, and state effective tax rate changes that impacted our
ending net deferred tax assets.

The change in the effective income tax rate for the year ended December 31, 2021
as compared to the prior year period is primarily due to the reduction in tax
benefit resulting from the accrual of non-deductible expenses related to changes
in fair value of contingent assets and liabilities.

For a discussion of our liquidity and capital resources related to our cash flow
activities for the fiscal year ended December 31, 2019, see "Part II, Item 7.
Management's Discussion and Analysis of Financial Condition and Results of
Operations" of our annual report on Form 10-K for the fiscal year ended December
31, 2020, filed with the SEC on February 25, 2021.

Net Cash Provided by Operating Activities



Net cash provided by operating activities of $53.9 million was primarily
comprised of net loss adjusted for the net effect of non-cash items such as the
change in fair value of contingent assets and liabilities of $72.4 million
(refer to Note 4, "Fair Value of Financial Instruments", for further details on
contingent consideration liabilities, including CVRs). The primary working
capital sources of cash were the timing of payments to large vendors as well as
an increase in billings associated with PYLARIFY sales. The primary working
capital use of cash were an increase in trade receivables from timing of sale
orders and an increase in collection period as well as the timing of inventory
purchases.

Net cash provided by operating activities of $16.4 million in the year ended
December 31, 2020 was driven primarily by a net loss of $13.5 million, a net
decrease of $22.4 million related to movements in our working capital accounts
during the period and a net decrease of $2.0 million in the fair value of
contingent assets and liabilities offset by $24.7 million of depreciation,
amortization and accretion expense, stock-based compensation expense of $14.1
million, impairment of long-lived assets of $9.9 million and a loss on disposal
of assets of $2.3 million. The overall decreases in cash from our working
capital accounts were primarily driven by the increase in accounts receivable
due to the Progenics Acquisition and increase in collection period as well as
change in inventory related to the COVID-19 impact on products and the timing of
payments and payments of accruals related to general and administrative expenses
in connection with the Progenics Acquisition.

Net Cash Provided by (Used in) Investing Activities



Net cash provided by investing activities during the year ended December 31,
2021 was primarily due to cash proceeds of $15.8 million received from the sale
of our Puerto Rico subsidiary, which was offset by $12.1 million of capital
expenditures.

Net cash used in investing activities during the year ended December 31, 2020
reflected $10.0 million in lending on a note receivable to Progenics prior to
the acquisition and $12.5 million in capital expenditures offset by $17.6
million of acquired cash related to the Progenics Acquisition.

Net Cash Used in Financing Activities



Net cash used in financing activities during the year ended December 31, 2021 is
primarily attributable to the payments on long-term debt and other borrowings of
$43.3 million related to the 2019 Term Facility and Royalty-Backed Loan,
including a voluntary repayment of the outstanding principal on the
Royalty-Backed Loan and payments for minimum statutory tax withholding related
to net share settlement of equity awards of $2.0 million offset by proceeds of
$5.3 million from stock option exercises.

Net cash used in financing activities during the year ended December 31, 2020 is
primarily attributable to the payments on long-term debt and other borrowings of
$15.5 million related to the 2019 Term Facility and Royalty-Backed Loan (defined
below), equity issuance costs related to the Progenics Acquisition of $3.8
million, and payments for minimum statutory tax withholding related to net share
settlement of equity awards of $2.1 million.

External Sources of Liquidity



In June 2019, we refinanced our 2017 $275.0 million five-year term loan facility
with the 2019 Term Facility. In addition, we replaced our $75.0 million
revolving facility with the 2019 Revolving Facility. The terms of the 2019 Term
Facility are set forth in the Credit Agreement, dated as of June 27, 2019, by
and among us, the lenders from time to time party thereto and Wells Fargo Bank,
N.A., as administrative agent and collateral agent (as amended, the "2019 Credit
Agreement"). We have the right to request an increase to the 2019 Term Facility
or request the establishment of one or more new incremental term loan
facilities, in an aggregate principal amount of up to $100.0 million, plus
additional amounts, in certain circumstances.

                                       69

We are permitted to voluntarily repay the 2019 Term Loans, in whole or in part,
without premium or penalty. The 2019 Term Facility requires us to make mandatory
prepayments of the outstanding 2019 Term Loans in certain circumstances. The
2019 Term Facility amortizes at 5.0% per year through September 30, 2022 and
7.5% thereafter, until its June 27, 2024 maturity date.

Under the terms of the 2019 Revolving Facility, the lenders thereunder agreed to
extend credit to us from time to time until June 27, 2024 consisting of
revolving loans in an aggregate principal amount not to exceed $200.0 million at
any time outstanding. The 2019 Revolving Facility includes a $20.0 million
sub-facility for the issuance of letters of credit (the "Letters of Credit").
The 2019 Revolving Facility includes a $10.0 million sub-facility for swingline
loans (the "Swingline Loans"). The Letters of Credit, Swingline Loans and the
borrowings under the 2019 Revolving Facility are expected to be used for working
capital and other general corporate purposes.

Please refer to Note 13, "Long-Term Debt, Net, and Other Borrowings" for further details on the 2019 Facility.



On June 19, 2020, we amended our 2019 Credit Agreement (the "Amendment") as a
result of the impact of the COVID-19 pandemic on our business and operations and
the near-term higher level of indebtedness resulting from our decision not to
immediately repay the Progenics debt secured by the RELISTOR royalties following
the Progenics Acquisition.

The Amendment provides for, among other things, modifications to our financial
maintenance covenants. The covenant related to Total Net Leverage Ratio (as
defined in the 2019 Credit Agreement) was waived from the date of the Amendment
through December 31, 2020. The maximum total net leverage ratio and interest
coverage ratio permitted by the financial covenant is displayed in the table
below:

                                2019 Credit Agreement
                          Period            Total Net Leverage Ratio
                Q3 2021 and thereafter                   3.50 to 1.00

                          Period            Interest Coverage Ratio
                Q2 2021 and thereafter                   3.00 to 1.00

As of December 31, 2021, we were in compliance with all financial and other covenants under the 2019 Credit Agreement.



Under the 2019 Credit Agreement, loans bear interest at LIBOR plus a spread that
ranges from 1.50% to 3.00% or the Base Rate plus a spread that ranges from 0.50%
to 2.00%, and the commitment fee ranges from 0.15% to 0.40%, in each case based
on our Total Net Leverage Ratio.

On June 19, 2020, as a result of the Progenics Acquisition, we assumed Progenics
outstanding debt as of such date in the amount of $40.2 million. On November 4,
2016, Progenics, through MNTX Royalties, entered into the Royalty-Backed Loan.
The Royalty-Backed Loan bore interest at an annual rate of 9.5% and was
scheduled to mature on June 30, 2025. On June 22, 2020, HCRP waived the
automatic acceleration of the Royalty-Backed Loan that otherwise would have been
triggered by the consummation of the Progenics Acquisition and MNTX Royalties
agreed not to prepay the loan until after December 31, 2020.

On March 31, 2021, we voluntarily repaid in full the entire outstanding principal on the Royalty-Backed Loan in the amount of $30.9 million, which included a prepayment amount of $0.5 million, and terminated the agreement.



Our ability to fund our future capital needs will be affected by our ability to
continue to generate cash from operations and may be affected by our ability to
access the capital markets, money markets or other sources of funding, as well
as the capacity and terms of our financing arrangements.

We may from time to time repurchase or otherwise retire our debt and take other
steps to reduce our debt or otherwise improve our balance sheet. These actions
may include prepayments of our term loans or other retirements or refinancing of
outstanding debt, privately negotiated transactions or otherwise. The amount of
debt that may be retired, if any, could be material and would be decided at the
sole discretion of our Board of Directors and will depend on market conditions,
our cash position and other considerations.

Funding Requirements

Our future capital requirements will depend on many factors, including:



•The level of product sales and the pricing environment of our currently
marketed products, particularly DEFINITY, PYLARIFY, as well as any additional
products that we may market in the future, including decreased product sales
resulting from the COVID-19 pandemic;

•Revenue mix shifts and associated volume and selling price changes that could result from contractual status changes with key customers and additional competition;

•The continued costs of the PYLARIFY commercial launch and our ability to successfully commercialize PYLARIFY;

•The costs of acquiring or in-licensing, developing, obtaining regulatory approval for, and commercializing, new products, businesses or technologies, together with the costs of pursuing opportunities that are not eventually consummated;

•Our investment in the further clinical development and commercialization of products and development candidates, including AZEDRA, 1095, and LMI 1195;

•The costs of investing in our facilities, equipment and technology infrastructure;

•The costs and timing of establishing or amending manufacturing and supply arrangements for commercial supplies of our products and raw materials and components;

•Our ability to have product manufactured and released from JHS and other manufacturing sites in a timely manner in the future, or to begin and ramp up our manufacturing of DEFINITY at our in-house manufacturing facility in an amount sufficient to meet our supply needs;



•The costs of further commercialization of our existing products, particularly
in international markets, including product marketing, sales and distribution
and whether we obtain local partners to help share such commercialization costs;

•The extent to which we choose to establish collaboration, co-promotion, distribution or other similar arrangements for our marketed products;

•The legal costs relating to maintaining, expanding and enforcing our intellectual property portfolio, pursuing insurance or other claims and defending against product liability, regulatory compliance, intellectual property or other claims;

•The cost of interest on any additional borrowings which we may incur under our financing arrangements; and

•The impact of sustained inflation on our costs of goods sold and operating expenses.



We are vulnerable to future supply shortages, especially for our single sourced
products. Disruption in our financial performance could also occur if we
experience significant adverse changes in product or customer mix, broad
economic downturns, sustained inflation, adverse industry or company conditions
or catastrophic external events, including pandemics such as COVID-19, natural
disasters and political or military conflict. If we experience one or more of
these events in the future, we may be required to further implement expense
reductions, such as a delay or elimination of discretionary spending in all
functional areas, as well as scaling back select operating and strategic
initiatives.

If our capital resources become insufficient to meet our future capital
requirements, we would need to finance our cash needs through public or private
equity offerings, debt financings, assets securitizations, sale-leasebacks or
other financing or strategic alternatives, to the extent such transactions are
permissible under the covenants of our 2019 Credit Agreement. Additional equity
or debt financing, or other transactions, may not be available on acceptable
terms, if at all. If any of these transactions require an amendment or waiver
under the covenants in our 2019 Credit Agreement, which could result in
additional expenses associated with obtaining the amendment or waiver, we will
seek to obtain such a waiver to remain in compliance with those covenants.
However, we cannot be assured that such an amendment or waiver would be granted,
or that additional capital will be available on acceptable terms, if at all.

At December 31, 2021, our only current committed external source of funds is our
borrowing availability under our 2019 Revolving Facility. We had $98.5 million
of cash and cash equivalents at December 31, 2021. Our 2019 Facility, as
amended, contains a number of affirmative, negative, reporting and financial
covenants, in each case subject to certain exceptions and materiality
thresholds. Incremental borrowings under the 2019 Revolving Facility, as
amended, may affect our ability to comply with the covenants in the 2019
Facility, as amended, including the financial covenants restricting consolidated
net leverage and interest coverage. Accordingly, we may be limited in utilizing
the full amount of our 2019 Revolving Facility, as amended, as a source of
liquidity.

The CVRs we issued in the Progenics Acquisition entitle holders thereof to
future cash payments of 40% of PYLARIFY net sales over (i) $100.0 million in
2022 and (ii) $150.0 million in 2023, which, if payable, we currently intend to
fund from our then-available cash. In no event will our aggregate payments under
the CVRs, together with any other non-stock consideration treated as paid in
connection with the Progenics Acquisition, exceed 19.9% (which we currently
estimate could be approximately $100.0 million) of the total consideration we
pay in the Progenics Acquisition. Refer to Note 4, "Fair Value of Financial
Instruments", for further details on contingent consideration liabilities.

Based on our current operating plans, including our prudent expense management
in response to the COVID-19 pandemic, we believe our balance of cash and cash
equivalents, which totaled $98.5 million as of December 31, 2021, along with
cash generated by ongoing operations and continued access to our 2019 Revolving
Facility, will be sufficient to satisfy our cash requirements over the next
twelve months and beyond. Our material cash requirements include the following
contractual and other obligations.

Debt



As of December 31, 2021, we had maturities of principal obligations related to
our 2019 Term Facility for an aggregate principal amount of $175.0 million, with
$11.3 million payable within twelve months. Future interest payments associated
with the 2019 Term Facility total $8.3 million, with $3.6 million payable within
twelve months.

Leases

We have operating lease arrangements for certain facilities, including corporate
and manufacturing space. As of December 31, 2021, we had fixed operating lease
payment obligations of $22.0 million, with $2.4 million payable within twelve
months.

We have lease arrangements for certain equipment. As of December 31, 2021, we
had fixed finance lease payment obligations of $0.8 million, with $0.4 million
payable within twelve months.

Purchase Obligations

We have purchase obligations that primarily consist of noncancelable obligations
related to minimum quantities of goods or services that have been committed to
be purchased on an annual basis. As of December 31, 2021, we had minimum
purchase obligations of $6.5 million, with $3.5 million due within twelve
months.

License Agreements



We have entered into license agreements in which fixed payments have been
committed to be paid on an annual basis. As of December 31, 2021, we had fixed
license payments of $0.3 million, with $0.1 million due within twelve months.
These amounts do not include potential milestone or contractual payment
obligations contingent upon the achievement or occurrence of future milestones
or events under our license agreements, because they are contingent and the
amounts and timing of such potential obligations are unknown or uncertain. We
may be required to pay additional amounts up to approximately $170.5 million in
contingent payments under our license agreements.

Other Long-Term Liabilities



Our other long-term liabilities in the consolidated balance sheet include the
fair values of contingent consideration liabilities including CVRs and
contingent consideration liabilities related to a previous acquisition completed
by Progenics in 2013. We may be required to pay up to approximately $100.0
million related to the CVRs and approximately $85.0 million related to the
contingent consideration. As of December 31, 2021, these contingent payments
were not expected to be payable within twelve months due to the uncertainty
around the timing of the future cash flows.

Our other long-term liabilities in the consolidated balance sheet include
unrecognized tax benefits and related interest and penalties. As of December 31,
2021, we had unrecognized tax benefits of $20.9 million, which included interest
and penalties, classified as noncurrent liabilities. At this time, we are unable
to make a reasonably reliable estimate of the timing of payments in individual
years in connection with these tax liabilities.

Asset Retirement Obligation



We are required to provide the Massachusetts Department of Public Health and the
New Jersey Department of Environmental Protection financial assurance
demonstrating our ability to fund the decommissioning of our North Billerica,
Massachusetts and Somerset, New Jersey production facilities upon closure,
although we have no current plans to close the facilities. We have provided this
financial assurance in the form of a $28.2 million surety bond (the "Surety
Bond"). As of December 31, 2021, the liability, which was approximately $20.8
million, was measured at the present value of the obligation expected to be
incurred of approximately $26.4 million. These contingent payments are not
expected to be payable within twelve months due to the uncertainty around the
timing of the future cash flows related to the decommissioning of our
radioactive operations.

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

Table of Contents

Off-Balance Sheet Arrangements



As noted above, we have provided the Surety Bond to the Massachusetts Department
of Public Health and New Jersey Department of Environmental Protection. Since
inception, we have not engaged in any other off-balance sheet arrangements,
including structured finance, special purpose entities or variable interest
entities.

Effects of Inflation



We do not believe that inflation has had a significant impact on our revenues or
results of operations. We expect our cost of product sales and other operating
expenses will change in the future in line with periodic inflationary changes in
price levels. Because we intend to retain and continue to use our property and
equipment, we believe that the incremental inflation related to the replacement
costs of those items will not materially affect our operations. However, the
rate of inflation affects our expenses, such as those for employee compensation
and contract services, which could increase our level of expenses and the rate
at which we use our resources. While we generally believe that we will be able
to offset the effect of price-level changes by adjusting our product prices and
implementing operating efficiencies, any material unfavorable changes in price
levels could have a material adverse effect on our financial condition, results
of operations and cash flows.

Recent Accounting Standards

Refer to Note 2, "Summary of Significant Accounting Policies," in the accompanying consolidated financial statements located under Item 8 of this Annual Report on Form 10-K for information regarding recently issued accounting standards that may have a significant impact on our business.

Critical Accounting Estimates



The discussion and analysis of our financial condition and results of operations
are based on our consolidated financial statements, which have been prepared in
accordance with U.S. GAAP. The preparation of these consolidated financial
statements require us to make estimates and judgments that affect our reported
assets and liabilities, revenues and expenses, and other financial information.
Actual results may differ materially from these estimates under different
assumptions and conditions. In addition, our reported financial condition and
results of operations could vary due to a change in the application of a
particular accounting standard.

We believe the following represent our critical accounting estimates used in the preparation of our financial statements.

Revenue from Contracts with Customers



Revenue is measured based on a consideration specified in a contract with a
customer, and excludes any sales incentives and amounts collected on behalf of
third parties. We recognize revenue when we satisfy our performance obligations
by transferring control over products or services to our customers. The amount
of revenue we recognize reflects the consideration to which we expect to be
entitled to receive in exchange for these goods or services. To achieve this
core principle, we apply the following five steps: (1) identify the contracts
with a customer; (2) identify the performance obligations in the contract; (3)
determine the transaction price; (4) allocate the transaction price to the
performance obligations in the contract; and (5) recognize revenue when (or as)
we satisfy performance obligations.

We derive our revenues through arrangements with customers for product sales as
well as licensing and royalty arrangements. We sell our products primarily to
clinics, distributors, group practices, hospitals, integrated delivery networks,
and radiopharmacies, and we consider customer purchase orders, which in some
cases are governed by master sales or group purchasing organization agreements,
to be contracts with our customers. In addition to these arrangements, we also
enter into licensing agreements under which we license certain rights to third
parties. The terms of these arrangements typically include payment to us of one
or more of the following: non-refundable, up-front license fees; development,
regulatory and commercial milestone payments; and royalties on net sales of
licensed products. We analyze various factors requiring management judgment when
applying the five-step model to our contracts with customers.

Our product revenues are recorded at the net sales price (transaction price),
which represents our sales price less estimates related to reserves which are
established for items such as discounts, returns, rebates and allowances that
may be provided for in certain contracts with our customers. Judgment is used in
determining and updating our reserves on an ongoing basis, and where
appropriate, these estimates take into consideration a range of possible
outcomes which are probability-weighted for relevant factors such as our
historical experience, current contractual and statutory requirements, specific
known market events and trends, industry data and forecasted customer buying and
payment patterns. Overall, these reserves reflect our best estimates of the
amount of consideration to which it is entitled based on the terms of the
contract. Actual amounts of consideration ultimately received may differ from
our estimates.

                                       73

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

Table of Contents




For our licensing and royalty arrangements, we use judgment in determining the
number of performance obligations in a license agreement by assessing whether
the license is distinct or should be combined with another performance
obligation as well as the nature of the license. As part of the accounting for
these arrangements, we develop assumptions that require judgment to determine
the stand-alone selling price for each performance obligation identified in a
contract. These key assumptions may include market conditions, reimbursement
rates for personnel costs, development timelines and probabilities of regulatory
success.

Business Combinations

We account for business combinations using the acquisition method of accounting.
We recognize the assets acquired and liabilities assumed in business
combinations on the basis of their fair values at the date of acquisition. We
assess the fair value of assets acquired, including intangible assets, and
liabilities assumed using a variety of methods. Each asset acquired and
liability assumed is measured at fair value from the perspective of a market
participant. The method used to estimate the fair values of intangible assets
incorporates significant assumptions regarding the estimates a market
participant would make in order to evaluate an asset, including a market
participant's use of the asset and the appropriate discount rates. Acquired
in-process research and development ("IPR&D") is recognized at fair value and
initially characterized as an indefinite-lived intangible asset, irrespective of
whether the acquired IPR&D has an alternative future use. Any excess purchase
price over the fair value of the net tangible and intangible assets acquired is
allocated to goodwill. Transaction costs and restructuring costs associated with
a business combination are expensed as incurred.

The fair values assigned to tangible and intangible assets acquired and
liabilities assumed are based on our estimates and assumptions, as well as other
information we have compiled, including valuations that utilize customary
valuation procedures and techniques. If the actual results differ from the
estimates and assumptions used in these estimates, it could result in a possible
impairment of the intangible assets and goodwill, a required acceleration of the
amortization expense of finite-lived intangible assets or the recognition of
additional consideration, which would be expensed.

During the measurement period, which extends no later than one year from the
acquisition date, we may record certain adjustments to the carrying value of the
assets acquired and liabilities assumed with the corresponding offset to
goodwill. After the measurement period, all adjustments are recorded in the
consolidated statements of operations as operating expenses or income.

Intangible and Long-Lived Assets



We test intangible and long-lived assets for recoverability whenever events or
changes in circumstances suggest that the carrying value of an asset or group of
assets may not be recoverable. We measure the recoverability of assets to be
held and used by comparing the carrying amount of the asset to future
undiscounted net cash flows expected to be generated by the asset. If those
assets are considered to be impaired, the impairment equals the amount by which
the carrying amount of the assets exceeds the fair value of the assets. Any
impairments are recorded as permanent reductions in the carrying amount of the
assets. Long-lived assets, other than goodwill and other intangible assets, that
are held for sale are recorded at the lower of the carrying value or the fair
market value less the estimated cost to sell.

Intangible assets, consisting of trademarks, customer relationships, currently
marketed products, licenses and developed technology are amortized in a method
equivalent to the estimated utilization of the economic benefit of the asset.

Our IPR&D represents intangible assets acquired in a business combination that
are used in research and development activities but have not yet reached
technological feasibility, regardless of whether they have alternative future
use. The primary basis for determining the technological feasibility or
completion of these projects is whether we have obtained regulatory approval to
market the underlying products in an applicable geographic region. Because
obtaining regulatory approval can include significant risks and uncertainties,
the eventual realized value of the acquired IPR&D projects may vary from their
fair value at the date of acquisition. We classify IPR&D acquired in a business
combination as an indefinite-lived intangible asset until the completion or
abandonment of the associated research and development efforts. Upon completion
of the associated research and development efforts, we will determine the useful
life and begin amortizing the assets to reflect their use over their remaining
lives. Upon permanent abandonment, we write-off the remaining carrying amount of
the associated IPR&D intangible asset. We test our IPR&D assets at least
annually or when a triggering event occurs that could indicate a potential
impairment and we recognize any impairment loss in our consolidated statements
of operations.

Contingent Consideration Liabilities



The Progenics Acquisition included certain contingent consideration liabilities,
including CVRs, as well as other contingent future payments. CVRs are based on
net sales generated by PYLARIFY in both 2022 and 2023. Other contingent future
payments are based on net sales targets for 1095 and AZEDRA and include a
commercialization milestone for 1095. The estimated fair value of contingent
consideration liabilities, initially measured and recorded on the acquisition
date, are considered to be a Level 3 instrument and are reviewed quarterly, or
whenever events or circumstances occur that indicate a change in fair value. The
contingent

                                       74

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

Table of Contents

consideration liabilities are recorded at fair value at the end of each reporting period with changes in estimated fair values recorded in general and administrative expenses in the consolidated statements of operations.



The estimated fair value is determined based on probability adjusted discounted
cash flows or Monte Carlo simulation models that include significant estimates
and assumptions pertaining to the period of expected milestone achievement,
probability of success, discount rates and sales targets. The most significant
unobservable inputs are the probabilities of achieving regulatory approval of
the development projects and subsequent commercial success.

Significant changes in any of the probabilities of success would result in a
significantly higher or lower fair value measurement. Significant changes in the
probabilities as to the periods in which milestones will be achieved would
result in a significantly lower or higher fair value measurement.
