LETTER TO  
SHAREHOLDERS

Robert A. Bradway, Chairman and  
Chief Executive Officer, Amgen Inc.

TO MY FELLOW SHAREHOLDERS:

Amgen performed very effectively in 
2022, reaching roughly 10 million patients 
around the world with our approved 
medicines, advancing many promising 
new medicines, delivering strong financial 
performance, and keeping the Company 
on track to achieve attractive growth 
through the end of the decade.

Total revenues in 2022 were up 1% from the 
prior year to a record $26.3 billion. We also 
achieved record non-GAAP earnings per 
share of $17.69, up 27% from the prior year, 
and free cash flow of $8.8 billion.1 

In a challenging year for the stock 
market as a whole, Amgen delivered 
total shareholder return in 2022 of 20%, 
ahead of the S&P 500 and the NASDAQ 

Biotechnology 

indices, both 
of which

declined last year. We returned 
approximately $10.5 billion to shareholders 
in 2022 through share repurchases and 
dividends, with our dividend increasing for 
the eleventh consecutive year, up 10% per 
share over 2021.

Our portfolio now includes 27 approved 
medicines, 16 of which generated record 
2022 sales and nine of which generated 
2022 sales in excess of $1 billion. Looking 
across our portfolio as a whole, we 
achieved healthy volume growth of 9% in 
2022, partially offset by a 5% decline in net 
selling price. 

A number of our innovative medicines 
performed particularly well last year, 
including our cholesterol treatment 
Repatha® (sales +16% versus the prior 
year), our osteoporosis medicines EVENITY® 
(+48%) and Prolia® (+12%), and several of 
our oncology and hematology therapies, 
such as Nplate® (+27%), BLINCYTO® (+24%), 
and KYPROLIS® (+13%). Two of our newest 
innovations – LUMAKRAS®/LUMYKRAS™ to 
treat a type of non-small cell lung cancer 
and TEZSPIRE® to treat severe asthma – 
collectively contributed more than $450 
million in 2022 sales, and we are pursuing 
additional indications for both.

2022 Letter to Shareholders  |  Amgenwe are advancing rapidly through clinical 
development. 

Olpasiran is being studied in patients 
with high levels of lipoprotein(a), a type 
of "bad" cholesterol that is genetically 
determined and cannot be modified by 
diet or exercise. Phase 2 data released 
in 2022 showed remarkable reductions 
in lipoprotein(a) levels of as much 
as 95% in patients with established 
cardiovascular disease. We are currently 
enrolling several thousand patients in a 
phase 3 cardiovascular outcomes trial. 

In parallel, we are conducting a study 
in the U.S. focused on Black Americans, 
who are twice as likely to have elevated 
lipoprotein(a) levels as non-Hispanic 
whites. We are collaborating with the 
Morehouse School of Medicine and the 
Association of Black Cardiologists on this 
study, recognizing that minorities are often 
underrepresented in clinical trials despite 
being more susceptible to many diseases 
than the general population. 

Tarlatamab is being studied as a 
treatment for relapsed/refractory small-
cell lung cancer (SCLC), a very aggressive 
disease where the five-year survival rate 
is a mere 3%. We released phase 1 data 
last year showing that tarlatamab 
delivered significant antitumor

2022 Letter to Shareholders  |  AmgenAMG 133 is a potential new medicine to 
treat obesity, one of the most pressing 
public health issues of our time. Once 
thought to be a matter of lifestyle 
solvable through “willpower,” obesity is 
now understood to be a complex, serious 
disease that affects approximately 750 
million people worldwide and one which 
can lead to a myriad of health problems. 
Last year, we announced results from a 
phase 1 trial showing that a once-monthly 
dose of AMG 133 produced weight loss 
that was notable for its degree, rate, and 
durability. We have initiated a phase 2 trial 
of AMG 133 and are studying additional, 
earlier-stage molecules to treat obesity, all 
with different mechanisms of action.

The three molecules described above are 
all “multispecific” medicines, which we 
believe represent the next wave of drug 
discovery. Multispecifics are medicines 
that have more than one target and can 
work in a variety of ways. For example, as 
is the case with olpasiran and tarlatamab, 
they can act as "molecular matchmakers," 
linking a disease-causing target to a 
potent natural effector in our bodies 
that acts upon that target. They also can 
bind to multiple targets, acting on each 
one in a highly specific manner, as is the 
case with AMG 133. Multispecifics give us 
the potential to tackle the approximately 
85% of disease-causing targets in the 
body that have long been considered 
"undruggable."

ACCESSING EXTERNAL INNOVATION

Even as we continue to invest heavily in our 
own pipeline, we also recognize that there 
is great innovation happening outside our 
Company. 

In October of last year, we acquired 
ChemoCentryx, Inc. (ChemoCentryx) 
for approximately $3.8 billion, net of 
cash acquired, adding to our portfolio 
TAVNEOS®, a first-in-class medicine to treat 
antineutrophil cytoplasmic autoantibody 
(ANCA)-associated vasculitis, an 
autoimmune disease that leads to 
inflammation and eventual destruction of 
small blood vessels in vital organs such as 
the kidneys. 

In December, we announced an 
agreement to acquire Horizon 
Therapeutics plc (Horizon) for $27.8 billion. 
The acquisition is expected to close in the 
first half of this year and will add a number 
of first-in-class biologic medicines to our 
portfolio that treat serious inflammatory 
diseases. Horizon’s best-selling product, 
TEPEZZA®, for example, is the first and 
only medicine approved in the U.S. for 
the treatment of active thyroid eye 
disease, a progressive and potentially 
vision-threatening disease that can cause 
symptoms such as eye bulging and 
double vision.

The strategic rationale behind both our 
acquisition of ChemoCentryx and our 
announced Horizon acquisition is the 
same. We believe that our decades 
of leadership in inflammation and 
nephrology, combined with our global 
presence and world-class biologic 
capabilities, will enable us to reach many

2022 Letter to Shareholders  |  Amgenmore patients with life-changing 
medicines like TAVNEOS and TEPEZZA 
than either company could achieve 
on its own.  We’re off to a strong start 
with TAVNEOS, which, combined with 
the medicines we expect to come to 
us through the Horizon acquisition, 
will enhance Amgen’s growth profile 
through the end of the decade and 
beyond, as these products are all 
early in their lifecycle – giving us the 
opportunity to positively impact their 
success over time.

Bemarituzumab and rocatinlimab 
are two additional first-in-class 
medicines that were sourced 
externally. Bemarituzumab came 
to us through our 2021 acquisition 
of Five Prime Therapeutics, Inc., an 
oncology-focused biotechnology 
company. Two phase 3 studies of 
bemarituzumab are underway in 
gastric cancer, which is the fifth-most-
common cause of cancer death 
worldwide and particularly prevalent 
in the Asia-Pacific region, with earlier-
stage trials exploring its use in other 
types of cancer. We are also enrolling 
patients with moderate-to-severe 
atopic dermatitis in a phase 3 trial of 
rocatinlimab in collaboration with our 
long-time partner in Japan, Kyowa 
Kirin Co., Ltd.

We will continue to pursue the best 
innovation, irrespective of where we 
find it.

OPERATING RESPONSIBLY

Society confronts many challenges 
and is increasingly looking to the 
business community for solutions.  
I’ll share two ways Amgen is looking  
to help.

2022 Letter to Shareholders  |  AmgenWe know, for example, that young people 
around the world do not have equal 
access to science education –  
a reality that the COVID-19 pandemic only 
served to exacerbate. And so in 2020 the 
Amgen Foundation and Harvard University 
launched LabXchange, a free, online 
science education platform that enables 
students to practice scientific experiments 
using interactive simulations of the same 
cutting-edge equipment found in modern 
biotech laboratories. In 2022, the Amgen 
Foundation announced that it would more 
than double its financial commitment to 
LabXchange over the next three years as 
part of a push to reach 50 million users 
worldwide by 2025. 

We also know that minority-owned 
businesses in the U.S. have all too often 

lacked the capital they need to flourish. 
Earlier this year, Amgen committed to 
investing $150 million in Project Black, 
a fund that will create minority-owned 
businesses of scale that can serve as 
suppliers to Fortune 500 companies that 
spend billions of dollars a year on outside 
goods and services. This is consistent with 
the goal Amgen set in 2020 to double 
our 2019 spend with diverse suppliers 
in the U.S. and triple our spend with 
Black-owned businesses by 2023. It’s 
also complementary to our participation 
in OneTen, a coalition of companies 
collectively seeking to hire 1 million Black 
Americans into good-paying jobs over the 
next 10 years. 

Environmental	sustainability	has	long	been	a	priority	for	Amgen,	with	the	Company	targeting	to	
achieve	carbon	neutrality	in	its	operations	by	2027,	along	with	reductions	in	water	used	and	waste	
disposed	of	40%	and	75%,	respectively6.	In	2022,	hundreds	of	Amgen	employees	participated	
in	International	Coastal	Cleanup®	day	–	the	17th	consecutive	year	that	we	have	been	a	part	
of	one	of	the	world’s	largest	efforts	to	keep	our	oceans	healthy.	Tanya	Nunez,	manager,	

Environmental	Health,	Safety	and	Sustainability,	organized	the	Company’s	first	cleanup	event	
at	our	Thousand	Oaks	headquarters	in	2005,	and	she	is	proud	to	see	that	our	participation

2022 Letter to Shareholders  |  AmgenAs	the	COVID-19	pandemic	recedes,	many	companies	have	
opted	to	bring	their	workers	back	to	the	office.	Amgen	has	made	
a	different	choice,	providing	our	office-based	employees	with	
continued	flexibility	to	determine,	together	with	their	manager,	
where, when, and how to get their work done. This has helped to 
keep	engagement	high	among	current	employees	and	it	has	also

than	sitting	in	rush-hour	traffic	–	was	a	top	priority	when	she	
began	searching	for	a	new	job.	“It’s	a	critical	time	in	my	kids’	lives

well-positioned to build on our leadership 
in the coming years. 

Everything we achieved last year, and 
everything we will achieve moving forward, 
is due to the hard work and commitment 
of our people. They are passionate about 
our mission to serve patients, they are 
clear on how their work contributes to 
our success, and they are ready to seize 
the many opportunities that await us. I’m 
grateful to all of them.

On behalf of Amgen's board of directors, 
our senior leadership team, and our 
employees around the world, I thank 
you for your continued support of our 
Company and the important work we do.

LEADING INTO THE FUTURE

This is an exciting time to be in 
biotechnology. The need for innovative 
medicines has never been greater, driven 
by a rapidly-aging global population. Our 
ability to innovate has never been greater, 
either, driven by remarkable advances 
in science and technology. Amgen has 
been a biotechnology leader for more 
than 40 years, and I believe we are very

FORWARD-LOOKING STATEMENTS

This communication contains forward-looking statements that are based on the current expectations and beliefs of Amgen. All statements, other than statements of historical fact, are 
statements	that	could	be	deemed	forward-looking	statements,	including	any	statements	on	the	outcome,	benefits	and	synergies	of	collaborations,	or	potential	collaborations,	with	any	other	
company	(including	BeiGene,	Ltd.,	Kyowa-Kirin	Co.,	Ltd.,		or	any	collaboration	to	manufacture	therapeutic	antibodies	against	COVID-19),	the	performance	of	Otezla® (apremilast) (including 
anticipated	Otezla	sales	growth	and	the	timing	of	non-GAAP	EPS	accretion),	the	Five	Prime	Therapeutics,	Inc.	acquisition,	the	Teneobio,	Inc.	acquisition,	the	ChemoCentryx,	Inc.	acquisition,	
or	the	proposed	acquisition	of	Horizon	Therapeutics	plc,	as	well	as	estimates	of	revenues,	operating	margins,	capital	expenditures,	cash,	other	financial	metrics,	expected	legal,	arbitration,	
political,	regulatory	or	clinical	results	or	practices,	customer	and	prescriber	patterns	or	practices,	reimbursement	activities	and	outcomes,	effects	of	pandemics	or	other	widespread	
health	problems	such	as	the	ongoing	COVID-19	pandemic	on	our	business,	and	other	such	estimates	and	results.	Forward-looking	statements	involve	significant	risks	and	uncertainties,	
including	those	discussed	below	and	more	fully	described	in	the	Securities	and	Exchange	Commission	reports	filed	by	Amgen,	including	our	most	recent	annual	report	on	Form	10-K	and	any	
subsequent	periodic	reports	on	Form	10-Q	and	current	reports	on	Form	8-K.	Unless	otherwise	noted,	Amgen	is	providing	this	information	as	of	the	date	of	this	communication	and	does	not	
undertake	any	obligation	to	update	any	forward-looking	statements	contained	in	this	document	as	a	result	of	new	information,	future	events	or	otherwise.

No	forward-looking	statement	can	be	guaranteed	and	actual	results	may	differ	materially	from	those	we	project.	Our	results	may	be	affected	by	our	ability	to	successfully	market	both	
new	and	existing	products	domestically	and	internationally,	clinical	and	regulatory	developments	involving	current	and	future	products,	sales	growth	of	recently	launched	products,	
competition	from	other	products	including	biosimilars,	difficulties	or	delays	in	manufacturing	our	products	and	global	economic	conditions.	In	addition,	sales	of	our	products	are	affected	
by	pricing	pressure,	political	and	public	scrutiny	and	reimbursement	policies	imposed	by	third-party	payers,	including	governments,	private	insurance	plans	and	managed	care	providers	
and	may	be	affected	by	regulatory,	clinical	and	guideline	developments	and	domestic	and	international	trends	toward	managed	care	and	healthcare	cost	containment.	Furthermore,	our	
research,	testing,	pricing,	marketing	and	other	operations	are	subject	to	extensive	regulation	by	domestic	and	foreign	government	regulatory	authorities.	We	or	others	could	identify	safety,	
side	effects	or	manufacturing	problems	with	our	products,	including	our	devices,	after	they	are	on	the	market.	Our	business	may	be	impacted	by	government	investigations,	litigation	and	
product	liability	claims.	In	addition,	our	business	may	be	impacted	by	the	adoption	of	new	tax	legislation	or	exposure	to	additional	tax	liabilities.	If	we	fail	to	meet	the	compliance	obligations	
in	the	corporate	integrity	agreement	between	us	and	the	U.S.	government,	we	could	become	subject	to	significant	sanctions.	Further,	while	we	routinely	obtain	patents	for	our	products	and	
technology,	the	protection	offered	by	our	patents	and	patent	applications	may	be	challenged,	invalidated	or	circumvented	by	our	competitors,	or	we	may	fail	to	prevail	in	present	and	future	
intellectual	property	litigation.	We	perform	a	substantial	amount	of	our	commercial	manufacturing	activities	at	a	few	key	facilities,	including	in	Puerto	Rico,	and	also	depend	on	third	parties	
for	a	portion	of	our	manufacturing	activities,	and	limits	on	supply	may	constrain	sales	of	certain	of	our	current	products	and	product	candidate	development.	An	outbreak	of	disease	or	
similar	public	health	threat,	such	as	COVID-19,	and	the	public	and	governmental	effort	to	mitigate	against	the	spread	of	such	disease,	could	have	a	significant	adverse	effect	on	the	supply	
of	materials	for	our	manufacturing	activities,	the	distribution	of	our	products,	the	commercialization	of	our	product	candidates,	and	our	clinical	trial	operations,	and	any	such	events	may	
have	a	material	adverse	effect	on	our	product	development,	product	sales,	business	and	results	of	operations.	We	rely	on	collaborations	with	third	parties	for	the	development	of	some	of	
our	product	candidates	and	for	the	commercialization	and	sales	of	some	of	our	commercial	products.	In	addition,	we	compete	with	other	companies	with	respect	to	many	of	our	marketed	
products	as	well	as	for	the	discovery	and	development	of	new	products.	Discovery	or	identification	of	new	product	candidates	or	development	of	new	indications	for	existing	products	cannot	
be	guaranteed	and	movement	from	concept	to	product	is	uncertain;	consequently,	there	can	be	no	guarantee	that	any	particular	product	candidate	or	development	of	a	new	indication	
for	an	existing	product	will	be	successful	and	become	a	commercial	product.	Further,	some	raw	materials,	medical	devices	and	component	parts	for	our	products	are	supplied	by	sole	
third-party	suppliers.	Certain	of	our	distributors,	customers	and	payers	have	substantial	purchasing	leverage	in	their	dealings	with	us.	The	discovery	of	significant	problems	with	a	product	
similar to one of our products that implicate an entire class of products could have a material adverse effect on sales of the affected products and on our business and results of operations. 
Our	efforts	to	collaborate	with	or	acquire	other	companies,	products	or	technology,	and	to	integrate	the	operations	of	companies	or	to	support	the	products	or	technology	we	have	acquired,	
may	not	be	successful.	A	breakdown,	cyberattack	or	information	security	breach	could	compromise	the	confidentiality,	integrity	and	availability	of	our	systems	and	our	data.	Our	stock	price	
is	volatile	and	may	be	affected	by	a	number	of	events.	Our	business	and	operations	may	be	negatively	affected	by	the	failure,	or	perceived	failure,	of	achieving	our	environmental,	social	and	
governance	objectives.	The	effects	of	global	climate	change	and	related	natural	disasters	could	negatively	affect	our	business	and	operations.	Global	economic	conditions	may	magnify	
certain	risks	that	affect	our	business.	Our	business	performance	could	affect	or	limit	the	ability	of	our	Board	of	Directors	to	declare	a	dividend	or	our	ability	to	pay	a	dividend	or	repurchase	
our	common	stock.	We	may	not	be	able	to	access	the	capital	and	credit	markets	on	terms	that	are	favorable	to	us,	or	at	all.

BUSINESS

PART I

Amgen Inc. (including its subsidiaries, referred to as “Amgen,” “the Company,” “we,” “our” or “us”) is a biotechnology 
company  committed  to  unlocking  the  potential  of  biology  for  patients  suffering  from  serious  illnesses  by  discovering, 
developing, manufacturing and delivering innovative human therapeutics. This approach begins by using tools like advanced 
human genetics to unravel the complexities of disease and understand the fundamentals of human biology.

Amgen focuses on areas of high unmet medical need and leverages its expertise to strive for solutions that improve health 
outcomes  and  dramatically  improve  people’s  lives.  A  biotechnology  pioneer,  Amgen  has  grown  to  be  one  of  the  world’s 
leading independent biotechnology companies, has reached millions of patients around the world and is developing a pipeline 
of medicines with breakaway potential.

Amgen  was  incorporated  in  California  in  1980  and  became  a  Delaware  corporation  in  1987.  We  have  a  presence  in 

approximately 100 countries worldwide. Amgen operates in one business segment: human therapeutics.

Significant Developments 

Following is a summary of significant developments affecting our business that have occurred and that we have reported 

since the filing of our Annual Report on Form 10-K for the year ended December 31, 2021. 

Acquisitions

Proposed acquisition of Horizon Therapeutics plc

• On December 12, 2022, we announced that we entered into a transaction agreement under which Amgen will acquire 
all shares of Horizon for $116.50 per share in cash for a transaction equity value of approximately $27.8 billion. In 
connection with the proposed acquisition of Horizon, in December 2022 we entered into a bridge credit agreement and 
a term loan credit agreement with an aggregate principal amount of $28.5 billion. Horizon is a global biotechnology 
company  headquartered  in  Dublin,  Ireland  and  is  focused  on  the  discovery,  development  and  commercialization  of 
medicines  that  address  critical  needs  for  people  impacted  by  rare,  autoimmune  and  severe  inflammatory  diseases. 
Horizon  has  12  marketed  medicines  and  a  pipeline  with  more  than  20  development  programs.  The  closing  of  this 
transaction is contingent upon satisfaction of certain regulatory (including FTC review) and other customary closing 
conditions.

◦ On  January  30,  2023,  the  Company  and  Horizon  each  received  a  request  for  additional  information  and 
documentary  materials  (Second  Request)  from  the  FTC  in  connection  with  the  FTC’s  review  of  the 
Company’s proposed acquisition of Horizon. The effect of the Second Request is to extend the waiting period 
imposed by the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, until 30 days after the 
Company and Horizon have substantially complied with the Second Request, unless that period is extended 
voluntarily by the Company and Horizon or terminated sooner by the FTC.

ChemoCentryx, Inc.

• On  October  20,  2022,  we  completed  our  acquisition  of  ChemoCentryx  for  $52.00  per  share  in  cash  totaling 

approximately $3.8 billion, net of cash acquired.

Products/Pipeline

Cardiometabolic

Repatha

• In 2022, we presented results from the Repatha FOURIER-OLE studies, two open label extension (OLE) studies (with 
6,635 patients) to the Phase 3 FOURIER cardiovascular (CV) outcomes trial. FOURIER-OLE was designed to assess 
the long-term safety and tolerability of Repatha in adults with clinically evident atherosclerotic cardiovascular disease 
(ASCVD). In these studies, an exploratory analysis demonstrated that earlier initiation of Repatha resulted in a lower 
risk of cardiovascular outcomes as defined by the composite endpoint of cardiovascular death, myocardial infarction 
(MI) and stroke, and the incidence of serious adverse events did not increase over time.

1

Olpasiran

• In  November  2022,  we  presented  positive  end-of-treatment  results  from  the  Phase  2  OCEAN(a)-DOSE  study 
evaluating olpasiran in adult patients with lipoprotein(a), or Lp(a), levels over 150 nmol/L and a history of ASCVD. 
Olpasiran  is  a  small  interfering  RNA  (siRNA)  designed  to  lower  the  body’s  production  of  apolipoprotein(a),  a  key 
component  of  Lp(a)  that  has  been  associated  with  an  increased  risk  of  CV  events.  In  the  double-blind  placebo-
controlled treatment period, olpasiran was administered up to 225 mg subcutaneously every 12 weeks to patients with 
a median baseline Lp(a) of approximately 260 nmol/L. Patients who received a 75 mg or higher dose every 12 weeks 
had a 95% or greater reduction in Lp(a) compared to placebo at week 36. Overall, the rates of adverse events were 
similar in the olpasiran and placebo arms.

Inflammation

TEZSPIRE

• In September 2022, the EC approved TEZSPIRE in the EU as an add-on therapy in patients 12 years and older with 
severe asthma who are inadequately controlled with high dose inhaled corticosteroids plus another medicinal product 
for maintenance treatment. The approval follows the recommendation by the CHMP of the EMA in July 2022.

ABP 654

• In April 2022, we announced preliminary results from a Phase 3 study evaluating the efficacy and safety of ABP 654 
compared to STELARA (ustekinumab) in adult patients with moderate-to-severe plaque psoriasis. The study met the 
primary efficacy endpoint, demonstrating no clinically meaningful differences between ABP 654 and STELARA.

Oncology/Hematology

LUMAKRAS/LUMYKRAS

• In April 2022, we announced long-term efficacy and safety data from the CodeBreaK 100 Phase 1/2 trial in patients 
with KRAS G12C–mutated advanced non-small cell lung cancer (NSCLC) who received LUMAKRAS/LUMYKRAS. 
In  174  heavily  pre-treated  patients  (172  with  baseline  measurable  lesion(s)),  LUMAKRAS/LUMYKRAS 
demonstrated a centrally confirmed objective response rate (ORR) of 40.7%, disease control rate of 83.7% and median 
duration of response (DOR) of 12.3 months. The results also showed median progression-free survival (PFS) of 6.3 
months and overall survival of 12.5 months, with 32.5% of patients still alive at two years. No new safety signals for 
LUMAKRAS/LUMYKRAS were identified with the long-term follow-up.

• In September 2022, we announced results from the global Phase 3 CodeBreaK 200 trial, which showed once-daily oral 
LUMAKRAS/LUMYKRAS  led  to  significantly  superior  PFS  (primary  endpoint)  and  a  significantly  higher  ORR  (a 
key secondary endpoint) in patients with KRAS G12C–mutated NSCLC, compared with intravenous chemotherapy, 
docetaxel.  LUMAKRAS/LUMYKRAS  significantly  improved  PFS  compared  to  docetaxel  in  heavily  pre-treated 
patients.  The  proportion  of  patients  with  PFS  at  one  year  was  25%  for  LUMAKRAS/LUMYKRAS  versus  10%  for 
docetaxel.  LUMAKRAS/LUMYKRAS  demonstrated  a  significantly  higher  ORR  than  docetaxel  with  double  the 
response rates in the LUMAKRAS/LUMYKRAS arm (28% versus 13%, respectively).

ABP 959

• In August 2022, we announced positive top-line results from the DAHLIA study, a randomized, double-blind, active-
controlled, two-period crossover Phase 3 study evaluating the efficacy and safety of ABP 959, a biosimilar candidate 
to  SOLIRIS  (eculizumab),  compared  with  SOLIRIS  in  adult  patients  with  paroxysmal  nocturnal  hemoglobinuria 
(PNH).  The  study  met  its  primary  endpoints,  demonstrating  no  clinically  meaningful  differences  between  ABP  959 
and SOLIRIS. The safety and immunogenicity profile of ABP 959 was comparable to that of SOLIRIS.

New manufacturing facility

• In  March  2022,  we  broke  ground  to  build  a  drug  substance  plant  in  North  Carolina  that  will  increase  our 

manufacturing network capacity.

Marketing, Distribution and Selected Marketed Products

The largest concentration of our sales and marketing forces is based in the United States and Europe. In recent years, we 
have expanded the commercialization and marketing of our products into other geographic territories, including Japan, China 
and other parts of Asia; Latin America; and the Middle East. This expansion has occurred, and is expected to continue to occur, 
by establishing our own affiliates, by acquiring existing third-party businesses or product rights or by collaborating with third 
parties. See Business Relationships for our significant alliances. Whether we use our own sales and marketing forces or a third 
party’s services varies across these markets. Such use typically depends on several factors, including the nature of entry into the 
new market, the size of an opportunity and operational capabilities. Together with our collaborators, we market our products to 
healthcare providers, including physicians or their clinics, dialysis centers, hospitals and pharmacies.

In  the  United  States,  substantially  all  of  our  sales  are  to  pharmaceutical  wholesale  distributors,  which  are  the  principal 
means  of  distributing  our  products  to  healthcare  providers.  We  also  market  certain  products  through  direct-to-consumer 
channels, including print, television and online media. For further discussion, see Government Regulation—Regulation in the 
United  States—Regulation  of  Product  Marketing  and  Promotion.  Outside  the  United  States,  we  sell  principally  to  healthcare 
providers  and/or  pharmaceutical  wholesale  distributors  depending  on  the  distribution  practice  in  each  country.  In  the  Asia 
Pacific region, we also sell our products in partnership with other companies, including Astellas Pharma Inc., BeiGene, KKC, 
Takeda Pharmaceutical Company Limited and Daiichi Sankyo Co., Ltd.

Our  product  sales  to  three  large  wholesalers,  McKesson  Corporation,  AmerisourceBergen  Corporation  and  Cardinal 
Health, Inc., each individually accounted for more than 10% of total revenues for each of the years 2022, 2021 and 2020. On a 
combined basis, these wholesalers accounted for 82%, 82% and 83% of worldwide gross revenues for 2022, 2021 and 2020, 
respectively. We monitor the financial condition of our larger customers and limit our credit exposure by setting credit limits 
and, in certain circumstances, by requiring letters of credit or obtaining credit insurance.

and is used primarily in indications for the treatment of adult patients with moderately to severely active rheumatoid arthritis, 
patients with chronic moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy and patients 
with active psoriatic arthritis.

Prolia

We  market  Prolia  in  many  countries  around  the  world.  Prolia  contains  the  same  active  ingredient  as  XGEVA  but  is 
approved for different indications, patient populations, dose and frequency of administration. Prolia was launched in the United 
States  and  Europe  in  2010.  In  the  United  States,  it  is  used  primarily  in  the  indication  for  the  treatment  of  postmenopausal 
women  with  osteoporosis  at  high  risk  of  fracture,  defined  as  a  history  of  osteoporotic  fracture,  or  multiple  risk  factors  for 
fracture;  or  in  patients  who  have  failed  or  are  intolerant  to  other  available  osteoporosis  therapy.  In  Europe,  Prolia  is  used 
primarily for the treatment of osteoporosis in postmenopausal women at increased risk of fracture.

Otezla

We market Otezla, a small molecule that inhibits phosphodiesterase 4 (PDE4), in many countries around the world. Otezla 
was  acquired  from  Bristol  Myers  Squibb  Company  in  November  2019  after  their  acquisition  of  Celgene.  Otezla  is  an  oral 
therapy approved for the treatment of adults with plaque psoriasis across all severities (United States and Japan) and moderate-
to-severe plaque psoriasis (other global markets including Europe), for adults with active psoriatic arthritis and for adults with 
oral ulcers associated with Behçet’s disease.

XGEVA

We  market  XGEVA  in  many  countries  around  the  world.  XGEVA  was  launched  in  2010  and  is  used  primarily  in  the 
indication for prevention of skeletal-related events (pathological fracture, radiation to bone, spinal cord compression or surgery 
to bone) in patients with bone metastases from solid tumors and multiple myeloma.

Aranesp

We market Aranesp primarily in the United States and Europe. Aranesp was launched in 2001 and is indicated to treat a 
lower-than-normal number of red blood cells (anemia) caused by chronic kidney disease (CKD) in both patients on dialysis and 
patients  not  on  dialysis.  Aranesp  is  also  indicated  for  the  treatment  of  anemia  due  to  concomitant  myelosuppressive 
chemotherapy in certain patients with nonmyeloid malignancies and when chemotherapy will be used for at least two months 
after starting Aranesp.

Nplate

We  market  Nplate  in  many  countries  around  the  world.  Nplate  was  launched  in  2008  and  is  indicated  to  treat 
thrombocytopenia  in  patients  with  chronic  immune  thrombocytopenia  (ITP)  who  have  had  an  insufficient  response  to 
corticosteroids, immunoglobulins or splenectomy.

Repatha

We  market  Repatha,  a  PCSK9  inhibitor,  in  many  countries  around  the  world.  Repatha  was  launched  in  2015  and  is 
indicated  to  reduce  the  risks  of  myocardial  infarction,  stroke  and  coronary  revascularization  in  adults  with  established  CV 
disease. Repatha is also indicated to reduce low-density lipoprotein cholesterol (LDL-C) in adults with primary hyperlipidemia, 
including heterozygous familial hypercholesterolemia (HeFH).

KYPROLIS

We market KYPROLIS primarily in the United States and Europe. KYPROLIS was launched in 2012 and is indicated in 
combination with (i) dexamethasone, (ii) lenalidomide plus dexamethasone and (iii) DARZALEX plus dexamethasone for the 
treatment of patients with relapsed or refractory multiple myeloma who have received one to three prior lines of therapy. It is 
also  approved  as  a  single  agent  for  patients  with  relapsed  or  refractory  multiple  myeloma  who  have  received  one  or  more 
previous therapies.

Neulasta

We  market  Neulasta,  a  pegylated  protein  based  on  the  filgrastim  molecule,  primarily  in  the  United  States  and  Europe. 
Neulasta was launched in 2002 and is used primarily in the indication to help reduce the chance of infection due to a low white 
blood cell count in patients with certain types of cancer (nonmyeloid) who receive anticancer medicines (chemotherapy) that 
can cause fever and a low blood cell count. In 2015, the Neulasta Onpro kit became available in the United States. The Neulasta 
Onpro kit provides physicians the opportunity to initiate administration of Neulasta on the same day as chemotherapy, with drug 
delivery of the recommended dose of Neulasta at home the day after chemotherapy, thereby saving the patient a trip back to the 
doctor.

EVENITY

Together  with  our  collaboration  partners,  we  market  EVENITY  in  many  countries  around  the  world.  EVENITY  was 
launched  in  the  United  States  and  Japan  in  2019.  In  the  United  States,  it  is  used  in  the  indication  for  the  treatment  of 
osteoporosis in postmenopausal women at high risk for fracture. In Japan, EVENITY is used primarily in the indication for the

Competition

We operate in a highly competitive environment. A number of our marketed products are indicated for disease areas in 
which  other  products  or  treatments  are  currently  available  or  are  being  pursued  by  our  competitors  through  R&D  activities. 
Additionally, some competitor-marketed products target the same genetic pathways as our recently launched marketed products 
or are currently in development. This competition could impact the pricing and market share of our products. We continue to 
pursue ways of increasing the value of our medicines through innovations during their life cycles, which can include expanding 
the disease areas for which our products are indicated and finding new methods to make the delivery of our medicines easier 
and less costly. Such activities can offer important opportunities for differentiation. For example, we market the Neulasta Onpro 
kit, which provides physicians the opportunity to initiate administration of the recommended dose of Neulasta on the same day 
as chemotherapy, with drug delivery at home the day after chemotherapy, thereby saving the patient a trip back to the doctor. 
We plan to continue pursuing innovation efforts to strengthen our competitive position. Such position may be based on, among 
other things, safety, efficacy, reliability, availability, patient convenience, delivery devices, price, reimbursement, access to and 
timing of market entry and patent position and expiration.

Certain  of  the  existing  patents  on  our  principal  products  have  expired,  and  we  face  new  and  increasing  competition, 
including from biosimilars and generics. A biosimilar is another version of a biological product for which marketing approval is 
sought  or  has  been  obtained  based  on  a  demonstration  that  it  is  “highly  similar”  to  the  original  reference  product.  We  have 
experienced adverse effects from biosimilar competition on our originator product sales. Companies have launched biosimilar 
versions  of  EPOGEN,  NEUPOGEN  and  Neulasta  and  have  approved  biosimilars  for  ENBREL.  Once  multiple  biosimilar 
versions  of  one  of  our  originator  products  have  launched,  competition  has  intensified  rapidly,  resulting  in  greater  net  price 
declines for both reference and biosimilar products and a greater effect on product sales. See also Government Regulation—
Regulation in the United States—Approval of Biosimilars. Although competitor biosimilars compete on price, we believe many 
patients, providers and payers will continue to place high value on the reputation, supply reliability and safety of our products. 
As additional biosimilar competitors come to market, we will continue to leverage our global experience to distinguish against 
both branded and biosimilar competition.

We  also  have  our  own  biosimilar  products  both  in  the  United  States  and  outside  of  U.S.  markets  that  are  competing 
against  branded  and  biosimilar  versions  of  our  competitors’  products.  In  2019,  Amgen  launched  MVASI,  a  biosimilar  to 
Avastin, and KANJINTI, a biosimilar to Herceptin; and in 2018, Amgen launched AMGEVITA, a biosimilar to HUMIRA in 
markets outside the United States. We have also received FDA approval of AMJEVITA, a biosimilar to HUMIRA for the U.S. 
market, which launched in January 2023. In 2020, we launched AVSOLA, a biosimilar to Remicade; and in 2021 we launched 
RIABNI, a biosimilar to Rituxan. We expect additional biosimilar competition against both our branded and biosimilar products 
in the future across markets.

Although  most  of  our  products  are  biologics,  some  are  small  molecule  products.  Because  the  FDA  approval  process 
permits  generic  manufacturers  to  rely  on  the  safety  and  efficacy  data  of  the  innovator  product  rather  than  having  to  conduct 
their  own  costly  and  time-consuming  clinical  trials,  generic  manufacturers  can  often  develop  and  market  their  competing 
versions of our small molecule products at much lower prices. For example, following loss of exclusivity of patents directed to 
cinacalcet,  the  active  ingredient  in  our  small  molecule  calcimimetic  Sensipar,  we  lost  a  significant  share  of  the  market  and 
corresponding  revenues  in  a  very  short  period  of  time.  See  Part  IV—Note  19,  Contingencies  and  commitments,  to  the 
Consolidated Financial Statements.

The introduction of new products, the development of new processes or technologies by competitors or the emergence of 
new  information  about  existing  products  may  result  in  (i)  increased  competition  for  our  marketed  products,  even  for  those 
protected by patents and/or (ii) reductions in the prices we receive from selling our products. In addition, the development of 
new  treatment  options  or  standards  of  care  may  reduce  the  use  of  our  products  or  may  limit  the  utility  and  application  of 
ongoing clinical trials of our product candidates. (As used in this document, the term clinical trials may include prospective 
clinical  trials,  observational  studies,  registries  and  other  studies.)  See  Item  1A.  Risk  Factors—Our  products  face  substantial 
competition  and  our  product  candidates  are  also  likely  to  face  substantial  competition  and  Item  1A.  Risk  Factors—We 
currently  face  competition  from  biosimilars  and  generics  and  expect  to  face  increasing  competition  from  biosimilars  and 
generics in the future.

Reimbursement 

Sales of our products are dependent on the availability and extent of coverage and reimbursement from third-party payers. 
In  many  markets  around  the  world,  these  payers,  including  government  health  systems,  private  health  insurers  and  other 
organizations,  remain  focused  on  reducing  the  cost  of  healthcare;  and  their  efforts  have  intensified  as  a  result  of  rising 
healthcare  costs,  economic  pressures  and  broader  challenges  generated  by  the  COVID-19  pandemic.  Drugs  remain  heavily 
scrutinized  for  cost  containment.  As  a  result,  payers  are  becoming  more  restrictive  regarding  the  use  of  biopharmaceutical 
products  and  are  scrutinizing  the  prices  of  these  products  while  requiring  a  higher  level  of  clinical  evidence  to  support  the 
benefits  such  products  bring  to  patients  and  the  broader  healthcare  system.  These  pressures  become  intensified  when  our 
products become subject to competition, including from biosimilars.

In  the  United  States,  healthcare  providers  and  other  entities  such  as  pharmacies  and  PBMs  are  reimbursed  for  covered 
services  and  products  they  deliver  through  both  private-payer  and  government  healthcare  programs  such  as  Medicare  and 
Medicaid. We provide negotiated rebates to healthcare providers, private payers, government payers and PBMs. In addition, we 
are  required  to  (i)  provide  rebates  or  discounts  on  our  products  that  are  reimbursed  through  certain  government  programs, 
including Medicare and Medicaid, and (ii) provide discounts to qualifying healthcare providers under the federal 340B Drug 
Pricing Program. 

Both private and some government payers use formularies to manage access to and utilization of drugs. A drug’s inclusion 
and favorable positioning on a formulary are essential to ensure patients have access to a particular drug. Even when access is 
available,  some  patients  abandon  their  prescriptions  for  economic  reasons.  Payers  continue  to  institute  cost  reduction  and 
containment  measures  that  lower  drug  utilization  and/or  spending  altogether  and/or  shift  a  greater  portion  of  the  costs  to 
patients. Such measures include, but are not limited to, more-limited benefit plan designs, higher patient co-pays or coinsurance 
obligations, limitations on patients’ use of commercial manufacturer co-pay payment assistance programs (including through 
co-pay  accumulator  adjustment  or  maximization  programs),  stricter  utilization  management  criteria  before  a  patient  may  get 
access to a drug, higher-tier formulary placement that increases the level of patient out-of-pocket costs and formulary exclusion, 
which effectively encourages patients and providers to seek alternative treatments or pay 100% of the cost of a drug. The use of 
such  measures  by  PBMs  and  insurers  has  continued  to  intensify  and  has  thereby  limited  Amgen  product  usage  and  sales. 
Furthermore, during the past few years, many PBMs and insurers have consolidated, resulting in a smaller number of PBMs and 
insurers  overseeing  a  large  portion  of  total  covered  lives  in  the  United  States.  As  a  result,  PBMs  and  insurers  have  greater 
market  power  and  negotiating  leverage  to  mandate  stricter  utilization  criteria  and/or  exclude  drugs  from  their  formularies  in 
favor of competitor drugs or alternative treatments. In highly competitive treatment markets such as the markets for ENBREL, 
Otezla,  Repatha  and  Aimovig,  PBMs  are  also  able  to  exert  negotiating  leverage  by  requiring  incremental  rebates  from 
manufacturers in order for them to gain and/or maintain their formulary position.

In addition to market actions taken by private and government payers in the United States, policy makers in both of the 
major  U.S.  political  parties  have  supported  policies  to  lower  drug  costs.  See  Item  1A.  Risk  Factors—Our  sales  depend  on 
coverage and reimbursement from government and commercial third-party payers, and pricing and reimbursement pressures 
have  affected,  and  are  likely  to  continue  to  affect,  our  profitability.  In  August  2022,  the  Inflation  Reduction  Act  (IRA)  was 
enacted  and  includes  provisions  requiring  that  (1)  beginning  in  2026,  mandatory  price  setting  be  introduced  in  Medicare  for 
certain drugs paid for under Parts B and D, whereby manufacturers must accept a price established by the government or face 
penalties on all U.S. sales (starting with 10 drugs in 2026, adding 15 in 2027 and 2028, and adding 20 in 2029 and subsequent 
years such that by 2031 approximately 100 drugs could be subject to such set prices); (2) starting in 2024, Medicare Part D be 
redesigned  to  cap  beneficiary  out-of-pocket  costs  and,  beginning  January  1,  2025,  Federal  reinsurance  be  reduced  in  the 
catastrophic  phase  (resulting  in  a  shift  and  increase  of  such  costs  to  Part  D  plans  and  manufacturers,  including  by  requiring 
manufacturer  discounts  on  certain  drugs);  and  (3)  beginning  October  1,  2022,  manufacturers  now  owe  rebates  on  drugs 
reimbursed  under  Medicare  Part  D  if  price  increases  outpace  inflation,  and  beginning  January  1,  2023,  now  owe  rebates  on 
drugs  reimbursed  under  Medicare  Part  B  if  price  increases  outpace  inflation.  Although  the  IRA  has  passed,  the  environment 
remains dynamic, and the Administration and Congress are continuing to consider drug pricing reforms.

Other  potential  policies  cover  a  wide  range  of  areas,  including  allowing  the  importation  of  drugs  from  other  countries; 
increasing  transparency  in  drug  pricing;  and  using  third-party  value  assessments  to  determine  drug  prices.  The  Infrastructure 
Investment  and  Jobs  Act,  signed  into  law  on  November  15,  2021,  requires  manufacturers  of  certain  Part  B–covered  drugs 
packaged in single-use containers to give refunds to the government starting in 2023 for discarded amounts. 

In  many  countries  other  than  the  United  States,  government-sponsored  healthcare  systems  are  the  primary  payers  for 
drugs  and  biologics.  With  increasing  budgetary  constraints  and/or  difficulty  in  understanding  the  value  of  medicines, 
governments  and  payers  in  many  countries  are  applying  a  variety  of  measures  to  exert  downward  price  pressure.  These 
measures  can  include  mandatory  price  controls,  price  referencing,  therapeutic-reference  pricing,  increases  in  mandates, 
incentives  for  generic  substitution  and  biosimilar  usage  and  government-mandated  price  cuts.  In  this  regard,  many  countries 
have  health  technology  assessment  organizations  that  use  formal  economic  metrics  such  as  cost-effectiveness  to  determine 
prices, coverage and reimbursement of new therapies; and these organizations are expanding in both established and emerging 
markets.  Many  countries  also  limit  coverage  to  populations  narrower  than  those  specified  on  our  product  labels  or  impose 
volume caps to limit utilization. We expect that countries will continue taking aggressive actions to seek to reduce expenditures 
on drugs and biologics. Similarly, fiscal constraints may also affect the extent to which countries are willing to approve new 
and  innovative  therapies  and/or  allow  access  to  new  technologies.  The  EU  is  currently  undergoing  a  review  and  possible 
revision of its pharmaceutical legislation, now scheduled to end in the first half of 2023, with implementation by 2025 or 2026. 
It is likely that this review will lead to proposals that will reduce intellectual property protection for new products, as well as 
change the reimbursement and regulatory landscape in ways that are difficult to predict at this point.

10

The dynamics and developments discussed above create pressures on the pricing and potential usage of our products and 
on the industry. Given the diverse interests in play between payers, biopharmaceutical manufacturers, policy makers, healthcare 
providers and independent organizations, if and whether the parties involved can achieve alignment on the matters discussed 
above remain unclear, and the outcome of any such alignment is difficult to predict. We remain focused on pricing our products 
responsibly and delivering breakthrough treatments for unmet medical needs. Amgen is committed to working with the entire 
healthcare community to ensure continued innovation and to facilitate patient access to needed medicines. We do this by:

•

•

•

•

•

•

•

investing billions of dollars annually in R&D;

pricing our medicines to reflect the value they provide;

developing more affordable therapeutic choices in the form of high-quality and reliably supplied biosimilars;

partnering with payers to share risk and accountability for health outcomes;

providing patient support and education programs; 

helping patients in financial need access our medicines; and

working with policy makers, patients and other stakeholders to establish a sustainable healthcare system with access to 
affordable care and in which patients and their healthcare professionals are the primary decision makers.

See Item 1A. Risk Factors—Our sales depend on coverage and reimbursement from government and commercial third-
party payers, and pricing and reimbursement pressures have affected, and are likely to continue to affect, our profitability and 
Item  1A.  Risk  Factors—Guidelines  and  recommendations  published  by  various  organizations  can  reduce  the  use  of  our 
products.

Manufacturing, Distribution and Raw Materials

Manufacturing

We believe we are a leader in the manufacture of biologics and that our manufacturing capabilities represent a competitive 
advantage. The products we manufacture consist of both biologics and small molecule drugs. The majority of our products are 
biologics  that  are  produced  in  living  cells  and  that  are  inherently  complex  due  to  naturally  occurring  molecular  variations. 
Highly  specialized  knowledge  and  extensive  process  and  product  characterization  are  required  to  transform  laboratory-scale 
processes  into  reproducible  commercial  manufacturing  processes.  Further,  our  expertise  in  the  manufacture  of  biologics 
positions us well for leadership in the global biosimilars market. For additional information regarding manufacturing facilities, 
see Item 2. Properties.

We have been innovating our manufacturing facilities designed to extend our manufacturing advantage by optimizing our 
manufacturing network and/or by mitigating risks while continuing to ensure adequate supply of our products. For example, our 
licensed  next-generation  biomanufacturing  plants  operating  in  Singapore  and  West  Greenwich,  Rhode  Island,  incorporate 
multiple innovative technologies into a single facility. Next-generation biomanufacturing plants require smaller manufacturing 
footprints  and  offer  greater  environmental  benefits,  including  reduced  consumption  of  water  and  energy  and  lower  levels  of 
carbon emissions. Within such plants, the equipment is portable and smaller, which provides greater flexibility and speed in the 
manufacture of different medicines simultaneously. This enables Amgen to respond to changing demands for its medicines with 
increased agility. The Singapore site also has a plant that has been approved by several agencies, including the FDA and EMA, 
to produce small molecule drugs for commercial manufacturing.

Our  internal  manufacturing  network  has  commercial  production  capabilities  for  bulk  manufacturing,  formulation,  fill, 
finish,  tableting  and  device  assembly.  These  activities  are  performed  within  the  United  States  and  its  territory  in  our  Puerto 
Rico, Rhode Island and California facilities as well as internationally in our Ireland, Netherlands and Singapore facilities. In 
addition, we use third-party contract manufacturers to supplement the capacity or capability of our commercial manufacturing 
network.

To support our clinical trials, we manufacture product candidates primarily at our California facilities. We also use third-

party contract manufacturers to supplement the capacity or capability of our overall clinical manufacturing network.

See Item 1A. Risk Factors for a discussion of the factors that could adversely impact our manufacturing operations and 

the global supply of our products. 

11

Distribution

We operate distribution centers in Puerto Rico, Kentucky, California and the Netherlands for worldwide distribution of 
the  majority  of  our  commercial  and  clinical  products.  We  also  use  third-party  distributors  to  supplement  distribution  of  our 
products worldwide.

Other

In addition to the manufacturing and distribution activities noted above, each of our manufacturing locations includes key 
manufacturing  support  functions  such  as  quality  control,  process  development,  engineering,  procurement,  production 
scheduling and warehousing. Certain of those manufacturing and distribution activities are highly regulated by the FDA as well 
as  international  regulatory  agencies.  See  Government  Regulation—Regulation  in  the  United  States—Regulation  of 
Manufacturing Standards.

Manufacturing Initiatives

As discussed above, we have been expanding capacity and advancing new innovations with multiple ongoing projects.

Our  next-generation  biomanufacturing  plant  at  our  West  Greenwich,  Rhode  Island,  campus,  the  first  of  its  kind  in  the 
United States, has been approved by the FDA and EMA. This plant expands our capacity to manufacture certain products for 
U.S. and global markets, as we receive regulatory approval in those markets.

In  November  2021,  we  broke  ground  for  our  newest  biomanufacturing  plant  located  in  New  Albany,  Ohio.  This  final 
product assembly and packaging plant will support the growing demand for Amgen’s medicines in the United States and will 
use state-of-the-art technologies.

In March 2022, we broke ground for our new multi-product drug substance manufacturing facility in Holly Springs, North 
Carolina.  The  new  plant  will  support  both  traditional  stainless  steel-fed  batch  manufacturing  and  next-generation  single-use 
technologies, allowing flexibility in the production of multiple products in one plant.

Amgen continues to embed environmental sustainability into the upfront design, development and execution of our new 
facilities. The new facilities under construction in North Carolina and Ohio contain many examples of environmental advances, 
including on-site photovoltaic renewable energy generation at both sites. We expect our North Carolina facility’s carbon, waste 
and  water  footprints  to  be  substantially  lower  than  those  at  a  traditional  drug  substance  manufacturing  plant,  and  we  expect 
lower footprints per unit produced as well at our Ohio facility compared with existing similar facilities.

See Item 1A. Risk Factors—Manufacturing difficulties, disruptions or delays could limit supply of our products and limit 

our product sales.

Raw Materials and Medical Devices

Certain raw materials, medical devices (including companion diagnostics) and components necessary for the commercial 
and/or  clinical  manufacturing  of  our  products  are  provided  by  and  are  the  proprietary  products  of  unaffiliated  third-party 
suppliers, certain of which may be our only sources for such materials. We currently attempt to manage the risk associated with 
such  suppliers  by  means  of  inventory  management,  relationship  management  and  evaluation  of  alternative  sources  when 
feasible. We also monitor the financial condition of certain suppliers and their ability to supply our needs. See Item 1A. Risk 
Factors—We rely on third-party suppliers for certain of our raw materials, medical devices and components.

We perform various procedures to help authenticate the sources of raw materials, including intermediary materials used in 
the  manufacture  of  our  products;  the  procedures  include  verification  of  country  of  origin  and  are  incorporated  into  the 
manufacturing processes we and our third-party contract manufacturers perform.

To  better  ensure  supply,  Amgen  has  a  risk  mitigation  strategy  that  uses  a  combination  of  methods,  including  multiple 
sources  or  backup  inventory  of  critical  raw  materials.  In  response  to  the  COVID-19  pandemic  and  as  part  of  our  ongoing 
business continuity efforts, we continue to closely monitor our inventory levels and have taken additional measures to mitigate 
against raw material supply interruption. See Item 1A. Risk Factors for a discussion of the factors that could adversely impact 
our manufacturing operations and the global supply of our products.

12

Government Regulation

Regulation by government authorities in the United States and other countries is a significant factor in the production and 
marketing of our products and our ongoing R&D activities. To clinically test, manufacture and market products for therapeutic 
use,  we  must  satisfy  mandatory  procedures  and  safety  and  effectiveness  standards  established  by  various  regulatory  bodies. 
Compliance  with  these  standards  is  complex,  and  failure  to  comply  with  any  of  these  standards  can  result  in  significant 
implications. See Item 1A. Risk Factors for a discussion of factors, including global regulatory implications, that can adversely 
impact our development and marketing of commercial products.

Regulation in the United States

In  the  United  States,  the  Public  Health  Service  Act;  the  FDCA;  and  the  regulations  promulgated  thereunder  as  well  as 
other  federal  and  state  statutes  and  regulations  govern,  among  other  things,  the  production,  research,  development,  testing, 
manufacture,  quality  control,  labeling,  storage,  record  keeping,  approval,  advertising,  promotion  and  distribution  of  our 
products in addition to the reporting of certain payments and other transfers of value to healthcare professionals and teaching 
hospitals.

Clinical Development and Product Approval. Drug development in our industry is complex, challenging and risky, and 
failure  rates  are  high.  Product  development  cycles  are  typically  very  long—approximately  10  to  15  years  from  discovery  to 
market. A potential new medicine must undergo many years of preclinical and clinical testing to establish its safety and efficacy 
for  use  in  humans  at  appropriate  dosing  levels  and  with  an  acceptable  risk–benefit  profile.  We  continue  to  work  toward 
reducing cycle times by applying our expertise in human genetics and innovation in technology, clinical trials and real-world 
evidence.

After  laboratory  analysis  and  preclinical  testing  in  animals,  we  file  an  IND  with  the  FDA  to  begin  human  testing. 

Typically, we undertake an FDA-designated three-phase human clinical testing program.

•

•

•

In phase 1, we conduct small clinical trials to investigate the safety and proper dose ranges of our product candidates in a 
small number of human subjects.

In  phase  2,  we  conduct  clinical  trials  to  investigate  side-effect  profiles  and  the  efficacy  of  our  product  candidates  in  a 
patient population larger than phase 1 but still relatively small, who have the disease or condition under study.

In phase 3, we conduct clinical trials to investigate the short- and long-term safety and efficacy of our product candidates, 
compared to commonly used treatments, in a large number of patients who have the disease or condition under study.

The FDA monitors the progress of each trial conducted under an IND and may, at its discretion, reevaluate, alter, suspend 
or  terminate  the  testing  based  on  data  accumulated  to  that  point  and  the  FDA’s  risk–benefit  assessment  with  regard  to  the 
patients  enrolled  in  the  trial.  The  results  of  preclinical  and  clinical  trials  are  submitted  to  the  FDA  in  the  form  of  either  a 
Biologics  License  Application  for  biologic  products  or  a  New  Drug  Application  for  small  molecule  products.  We  are  not 
permitted to market or promote a new product until the FDA has approved our marketing application.

Approval of Biosimilars. The Affordable Care Act authorized the FDA to approve biosimilars via a separate, abbreviated 
pathway. The pathway allows sponsors of a biosimilar to seek and obtain regulatory approval based in part on the nonclinical-
trial and clinical-trial data of an originator product to which the biosimilar has been demonstrated to be “highly similar” and to 
have no clinically meaningful differences with regard to safety, purity and potency. The relevance of demonstrating “similarity” 
is that in many cases, biosimilars can be brought to market without conducting the full suite of clinical trials typically required 
of  originators,  because  risk–benefit  has  previously  been  established.  To  preserve  incentives  for  future  innovation,  the  law 
establishes a period of exclusivity for originators’ products, which in general prohibits biosimilars from gaining FDA approval 
based in part on reliance on or reference to the originator’s data in their application to the FDA for 12 years after initial FDA 
approval of the originator product. The law does not change the duration of patents granted on biologic products. As part of the 
implementation of the abbreviated approval pathway for biosimilars, the FDA released a number of guidance documents, some 
of which remain in draft form. See Item 1A. Risk Factors—We currently face competition from biosimilars and generics and 
expect to face increasing competition from biosimilars and generics in the future.

13

Regulation of Product Marketing and Promotion. The FDA regulates the marketing and promotion of drug products. Our 
product  promotions  for  approved  product  indications  must  comply  with  the  statutory  standards  of  the  FDCA  and  the  FDA’s 
implemented  regulations  and  guidance.  The  FDA’s  review  of  marketing  and  promotional  activities  encompasses  but  is  not 
limited  to  direct-to-consumer  advertising,  healthcare-provider-directed  advertising  and  promotion,  sales  representative 
communications to healthcare professionals, promotional programming and promotional activities involving electronic media. 
The FDA may also review industry-sponsored scientific and educational activities that make representations regarding product 
safety  or  efficacy  in  a  promotional  context.  The  FDA  may  take  enforcement  action  against  a  company  for  promoting 
unapproved uses of a product or for other violations of the FDA’s advertising and labeling laws and regulations. Enforcement 
action may include product seizures, injunctions, civil or criminal penalties or regulatory letters, which may require corrective 
advertising or other corrective communications to healthcare professionals. Failure to comply with the FDA’s regulations also 
can  result  in  adverse  publicity  or  increased  scrutiny  of  company  activities  by  the  U.S.  Congress  or  other  legislators. 
Additionally, as described below, such failure may lead to additional liability under U.S. healthcare fraud and abuse laws.

Regulation  of  Manufacturing  Standards.  The  FDA  regulates  and  inspects  the  equipment,  facilities,  laboratories  and 
processes  used  in  the  manufacturing  and  testing  of  products  prior  to  granting  approval  to  market  products.  If  after  receiving 
approval  from  the  FDA  we  make  a  material  change  in  manufacturing  equipment,  location  or  process,  additional  regulatory 
review  may  be  required.  We  also  must  adhere  to  current  Good  Manufacturing  Practice  regulations  and  product-specific 
regulations  enforced  by  the  FDA  through  its  facilities  inspection  program.  The  FDA  conducts  regular,  periodic  visits  to 
reinspect our equipment, facilities, laboratories and processes following an initial approval.

Regulation  of  Combination  Products.  Combination  products  are  defined  by  the  FDA  as  products  composed  of  two  or 
more  regulated  components  (e.g.,  a  biologic  and/or  drug  and  a  device).  Biologics/drugs  and  devices  each  have  their  own 
regulatory  requirements,  and  combination  products  may  have  additional  requirements.  A  number  of  our  marketed  products 
meet this definition and are regulated under this framework, and we expect that a number of our pipeline product candidates 
will be evaluated for regulatory approval under this framework as well.

Regulation outside the United States

In EU countries as well as in the United Kingdom, Switzerland, Canada, Australia and Japan, regulatory requirements and 

approval processes are similar in principle to those in the United States.

In the EU, there are currently two potential tracks for seeking marketing approval for a product not authorized in any EU 
member state: a decentralized procedure and a centralized procedure. In the decentralized procedure, identical applications for 
marketing  authorization  are  submitted  simultaneously  to  the  national  regulatory  agencies.  Regulatory  review  is  led  by  one 
member  state  (the  reference-member  state),  and  its  assessment—based  on  safety,  quality  and  efficacy—is  reviewed  and 
approved  (assuming  there  are  no  concerns  that  the  product  poses  a  serious  risk  to  public  health)  by  the  other  member  states 
from which the applicant is seeking approval (the concerned-member states). The decentralized procedure leads to a series of 
single national approvals in all relevant countries. In the centralized procedure, which is required of all products derived from 
biotechnology, a company submits a single Marketing Authorisation Application to the EMA, which conducts an evaluation of 
the dossier, drawing upon its scientific resources across Europe. If the drug product is proven to fulfill requirements for quality, 
safety and efficacy, the EMA’s CHMP adopts a positive opinion, which is transmitted to the EC for final decision on granting 
of the marketing authorization. Even though the EC generally follows the CHMP’s opinion, it is not bound to do so. Subsequent 
commercialization is enabled by country-by-country reimbursement approval.

In the EU, biosimilars are approved under a specialized pathway of the centralized procedure. As with the U.S. pathway, 
an applicant seeks and obtains regulatory approval for a biosimilar once the data exclusivity period for the original reference 
product  has  expired,  relying  in  part  on  the  data  submitted  for  the  originator  product  together  with  data  evidencing  that  the 
biosimilar  is  “highly  similar”  with  regard  to  quality,  safety  and  efficacy  to  the  original  reference  product  authorized  in  the 
European Economic Area. See Item 1A. Risk Factors—We currently face competition from biosimilars and generics and expect 
to face increasing competition from biosimilars and generics in the future.

Other countries such as those in Latin America and the Middle East have review processes and data requirements similar 
to  those  of  the  EU  and  in  some  cases  can  rely  on  prior  marketing  approval  from  U.S.  or  EU  regulatory  authorities.  The 
regulatory  process  in  these  countries  may  include  manufacturing/testing  facility  inspections,  testing  of  drug  product  upon 
importation and other domestic requirements.

14

In Asia Pacific, a number of countries such as China, Japan, South Korea and Taiwan may require local clinical-trial data 
for bridging purposes as part of the drug registration process in addition to global clinical trials, which can add to overall drug 
development and registration timelines. In most of the Asian markets, registration timelines depend on marketing approval in 
the United States or the EU. In some markets in Asia, such as China, Indonesia and Thailand, regulatory timelines can be less 
predictable.  The  regulatory  process  may  also  include  manufacturing/testing  facility  inspections,  testing  of  drug  product  upon 
importation  and  other  domestic  requirements.  Countries  such  as  Australia  and  Japan  have  more-mature  systems  that  would 
allow  for  submissions  under  more-competitive  time  frames.  With  regard  to  biosimilars,  several  of  these  countries  have 
pathways  to  register  biosimilars  (e.g.,  Australia,  India,  Singapore,  South  Korea  and  Taiwan),  and  biosimilar  products  are 
already present on the markets (e.g., Australia and South Korea).

In  some  countries,  such  as  Japan  and  those  in  the  EU,  medical  devices  may  be  subject  to  regulatory  regimes  whereby 
manufacturers must establish that their medical devices conform to essential requirements set out in the law for the particular 
device  category.  For  example,  in  the  EU,  with  limited  exceptions,  medical  devices  placed  on  the  market  must  bear  the 
Conformité Européenne marking to indicate their conformity with legal requirements.

Postapproval Phase

After approval, we continue to monitor adverse events and product complaints reported following the use of our products 
through  routine  postmarketing  surveillance  and  studies  when  applicable.  We  report  such  events  to  the  appropriate  regulatory 
agencies as required by local regulations for individual cases and aggregate reports. We proactively monitor (according to good 
pharmacovigilance practices) and ensure the implementation of signal detection, assessment and the communication of adverse 
events that may be associated with the use of our products. We also proactively monitor product complaints through our quality 
systems, which includes assessing our drug delivery devices for device complaints, adverse events and malfunctions. We may 
also  be  required  by  regulatory  agencies  to  conduct  further  clinical  trials  on  our  marketed  products  as  a  condition  of  their 
approval or to provide additional information on safety and efficacy. Health regulators, including the FDA, have authority to 
mandate labeling changes to products at any point in a product’s life cycle based on new safety information or as part of an 
evolving label change to a particular class of products.

Health  regulators,  including  the  FDA,  also  have  authority  both  before  and  after  approval  to  require  that  a  company 
implement  a  risk  management  program  for  a  product  to  ensure  that  the  benefits  of  the  drug  outweigh  the  risks.  Each  risk 
management  program  is  unique  and  varies  depending  on  the  specific  factors  required.  In  the  United  States,  such  a  risk 
management program is known as a REMS, and we currently have REMSs for Prolia, Nplate and BLINCYTO.

Other Regulation

We are also subject to various laws pertaining to healthcare fraud and abuse, including antikickback laws and false-claims 
laws.  Antikickback  laws  make  it  illegal  to  solicit,  offer,  receive  or  pay  any  remuneration  in  exchange  for  or  to  induce  the 
referral of business, including the purchase or prescribing of a particular drug that is reimbursed by a state or federal program. 
False-claims  laws  prohibit  knowingly  and  willingly  presenting  or  causing  to  be  presented  for  payment  to  third-party  payers 
(including Medicare and Medicaid) any claims for reimbursed drugs or services that are false or fraudulent, claims for items or 
services not provided as claimed or claims for medically unnecessary items or services. Violations of fraud and abuse laws may 
be punishable by criminal and/or civil sanctions, including fines and civil monetary penalties, as well as by the possibility of 
exclusion  from  federal  healthcare  programs  (including  Medicare  and  Medicaid).  Liability  under  false-claims  laws  may  also 
arise  when  violation  of  certain  laws  or  regulations  related  to  the  underlying  product  (e.g.,  a  violation  regarding  improper 
promotional activity or unlawful payments) contributes to the submission of a false claim.

On  April  25,  2019,  we  entered  into  a  settlement  agreement  with  the  DOJ  and  the  OIG  of  the  HHS  to  settle  certain 
allegations  related  to  our  support  of  independent  charitable  organizations  that  provide  patients  with  financial  assistance  to 
access medicines. Additionally, we entered into a corporate integrity agreement that requires us to both maintain a corporate 
compliance program and undertake a set of defined corporate integrity obligations for a period of five years. Due to the breadth 
of the statutory provisions and the absence of guidance in the form of regulations or court decisions addressing some of our 
practices, it is possible that in the future, our practices might be further challenged under antikickback or similar laws. 

The  FCPA  prohibits  U.S.  corporations  and  their  representatives  from  offering,  promising,  authorizing  or  making 
payments to any foreign government official, government staff member, political party or political candidate in an attempt to 
obtain or retain business abroad. The scope of the FCPA arguably includes interactions with certain healthcare professionals in 
many countries. Other countries have enacted similar anticorruption laws and/or regulations. Failure by our employees, agents, 
contractors,  vendors,  licensees,  partners  or  collaborators  to  comply  with  the  FCPA  and  other  anticorruption  laws  and/or 
regulations could result in significant civil or criminal penalties.

We  are  subject  to  various  laws  and  regulations  globally  with  regard  to  privacy  and  data  protection.  These  laws  and 
regulations involve the collection, storage, handling, use, disclosure, transfer and security of personal data. The legislative and 
regulatory environments regarding privacy and data protection are continually evolving and developing because these issues are 
subjects of increasing amounts of attention in countries globally. For example, we are subject to the EU’s GDPR, which became 
effective on May 25, 2018; the CCPA, which became effective on January 1, 2020; the California Privacy Rights Act of 2020, 
which amended the CCPA and became effective on January 1, 2023; and China’s Personal Information Protection Law, which 
became effective on November 1, 2021. Other jurisdictions where we operate have enacted or proposed similar legislation and/
or regulations. For example, Virginia, Colorado, Utah and Connecticut have all subsequently passed similar consumer privacy 
laws, which went into effect in Virginia as of January 1, 2023, and will go into effect in Colorado, Utah and Connecticut later in 
2023. Failure to comply with these laws could result in significant penalties.

Our  business  has  been  and  will  continue  to  be  subject  to  various  other  U.S.  and  foreign  laws,  rules  and  regulations, 

including provisions of the IRA. See Reimbursement section above.

Research and Development and Selected Product Candidates

We  focus  our  R&D  on  novel  human  therapeutics  for  the  treatment  of  serious  illness.  We  capitalize  on  our  strengths  in 
human  genetics,  novel  biology  and  protein  engineering.  We  leverage  our  biologic  expertise  and  seek  to  choose  the  optimal 
modality for a drug target and disease. And we use cutting-edge science and technology to study subtle biological mechanisms 
in search of therapies that will improve the lives of those who suffer from diseases.

Our discovery research programs may therefore yield targets that lead to the development of human therapeutics delivered 
as large molecules, small molecules, other combination modalities or new modalities. We have reshaped our portfolio and have 
increasingly focused our efforts on human genetics when possible to enhance the likelihood of success.

Since early 2021, efforts have been under way to control the COVID-19 pandemic. However, uncertainty remains as to 
the efficacy of these activities with respect to the ongoing trajectory of the pandemic. Challenges to vaccination efforts, new 
variants  and  other  causes  of  virus  spread  may  require  governments  to  change  restrictions  and/or  shutdown  requirements  in 
various geographies. As a result, we expect to see continued volatility for at least the duration of the pandemic as governments 
respond  to  current  local  conditions.  With  regard  to  our  clinical  trial  activities,  we  are  continuously  monitoring  COVID-19 
infection  rates,  including  changes  from  new  variants;  we  are  working  to  mitigate  effects  on  future  study  enrollment  in  our 
clinical trials; and we are evaluating the impact in all relevant countries. We remain focused on supporting our active clinical 
sites in their providing care for patients and in our providing investigational drug supply.

For  the  years  ended  December  31,  2022,  2021  and  2020,  our  R&D  expenses  were  $4.4  billion,  $4.8  billion  and  $4.2 

billion, respectively.

We have major R&D centers in Thousand Oaks and San Francisco, California; Iceland; and the United Kingdom, as well 

as smaller research centers and development facilities globally. See Item 2. Properties.

Our clinical trial activities are conducted by both our internal staff and third-party contract clinical trial service providers. 
To increase the number and diversity of patients available for enrollment in our clinical trials, we have opened clinical sites and 
will continue opening clinical sites and enrolling patients in a number of geographic locations. See Government Regulation—
Regulation in the United States—Clinical Development and Product Approval for a discussion of government regulation over 
clinical development. Also see Item 1A. Risk Factors—We must conduct clinical trials in humans before we commercialize and 
sell any of our product candidates or existing products for new indications.

Some of our competitors are actively engaged in R&D in areas in which we have products or in which we are developing 
product  candidates  or  new  indications  for  existing  products.  For  example,  we  compete  with  other  clinical  trials  for  eligible 
patients,  which  may  limit  the  number  of  available  patients  who  meet  the  criteria  for  certain  clinical  trials.  The  competitive 
marketplace  for  our  product  candidates  is  greatly  dependent  on  the  timing  of  entry  into  the  market.  Early  entry  may  have 
important  advantages  in  gaining  product  acceptance,  thereby  contributing  to  a  product’s  eventual  success  and  profitability. 
Accordingly, we expect that in some cases, the relative speed with which we can develop products, complete clinical testing, 
receive regulatory approval and supply commercial quantities of a product to the market will be important to our competitive 
position.

In addition to product candidates and marketed products generated from our internal R&D efforts, we acquire companies, 
acquire and license certain product and R&D technology rights and establish R&D arrangements with third parties to enhance 
our  strategic  position  within  our  industry  by  strengthening  and  diversifying  our  R&D  capabilities,  product  pipeline  and 
marketed product base. In pursuing these R&D arrangements and licensing or acquisition activities, we face competition from 
other  pharmaceutical  and  biotechnology  companies  that  also  seek  to  license  or  acquire  technologies,  product  candidates  or 
marketed products from those entities performing the R&D.

Business Relationships

From time to time, we enter into business relationships, including joint ventures and collaborative arrangements, for the 
R&D, manufacture and/or commercialization of products and/or product candidates. In addition, we acquire product and R&D 
technology rights and establish R&D collaborations with third parties to enhance our strategic position within our industry by 
strengthening  and  diversifying  our  R&D  capabilities,  product  pipeline  and  marketed-product  base.  These  arrangements 
generally provide for nonrefundable upfront license fees, development and commercial-performance milestone payments, cost 
sharing, royalties and/or profit sharing. The activities under these collaboration agreements are performed with no guarantee of 
either technological or commercial success, and each is unique in nature.

Trade secret protection for our unpatented confidential and proprietary information is important to us. To protect our trade 
secrets,  we  generally  require  counterparties  to  execute  confidentiality  agreements  upon  commencement  of  a  business 
relationship with us. However, others could either develop independently the same or similar information or unlawfully obtain 
access to our information.

BeiGene, Ltd.

In January 2020, we acquired an equity stake in BeiGene for approximately $2.8 billion in cash as part of a collaboration 
to expand our oncology presence in China. For additional information regarding our equity investment in BeiGene, see Part IV
—Note 9, Investments, to the Consolidated Financial Statements. Under the collaboration, BeiGene began selling XGEVA in 
2020, BLINCYTO in 2021 and KYPROLIS in 2022 in China, and Amgen shares profits and losses equally during the initial 
product-specific commercialization periods; thereafter, product rights may revert to Amgen, and Amgen will pay royalties to 
BeiGene on sales in China of such products for a specified period. Amgen manufactures and supplies the collaboration products 
to BeiGene.

In addition, we jointly develop a portion of our oncology portfolio with BeiGene, which shares in global R&D costs by 
providing  cash  and  development  services  of  up  to  $1.25  billion.  Upon  regulatory  approval,  BeiGene  will  assume 
commercialization  rights  in  China  for  a  specified  period,  and  Amgen  and  BeiGene  will  share  profits  equally  until  certain  of 
these product rights revert to Amgen. Upon return of the product rights, Amgen will pay royalties to BeiGene on sales in China 
for a specified period. For product sales outside China, Amgen will also pay royalties to BeiGene.

Human Capital Resources

Overview

Amgen’s  approach  to  human  capital  resource  management  starts  with  our  mission  to  serve  patients.  We  strive  to  serve 
patients by transforming the promise of science and biotechnology into therapies that have the power to restore health or save 
lives. The way we approach our business is guided by our Amgen Values:

Amgen Values

Be Science-Based

Compete Intensely and Win

Create Value for Patients, 
Staff and Stockholders

Be Ethical

Trust and Respect Each Other

Ensure Quality

Work in Teams

Collaborate, Communicate 
and Be Accountable

Our staff are also guided by the Company’s Code of Conduct, which is designed to help every person who does business 
on our behalf worldwide (including all staff, management, consultants, contract workers and temporary workers) to understand 
what is expected of them.

Our  industry  exists  in  a  complex  regulatory  and  reimbursement  environment.  The  unique  demands  of  our  industry, 
together  with  the  challenges  of  running  an  enterprise  focused  on  the  discovery,  development,  manufacture  and 
commercialization of innovative medicines, requires a highly engaged and committed workforce.

As  of  December  31,  2022,  Amgen  had  approximately  25,200  staff  members  in  over  50  countries,  and  we  have  had 
relatively  low  global  turnover  rates  compared  to  available  industry  information.  We  also  supplement  our  workforce  with 
independent  contractors,  contingent  workers  and  temporary  workers,  as  needed.  Outside  of  the  United  States,  some  of  our 
employees  are  represented  by  unions  or  works  councils.  We  consider  our  staff  relations  to  be  good,  supported  by  regular 
assessments of staff engagement surveys on a wide range of topics (including flexible work environments, diversity, inclusion 
and belonging, and maintaining a culture of compliance). We discuss the results of these surveys with our workforce and our 
Board of Directors. Reflecting our staff members’ desire to retain flexibility to work virtually as COVID-19 related restrictions 
eased and sites became more accessible, we implemented a flexible workspace initiative that enables many employees to work 
together with their manager to determine the location that best enables their work at hand, supporting virtual work as well as 
coming on site.

Compensation, Benefits and Development

Our  approach  to  employee  compensation  and  benefits  is  designed  to  deliver  cash,  equity  and  benefit  programs  that  are 
competitive  with  those  offered  by  leading  companies  in  the  biotechnology  and  pharmaceutical  industries,  and  to  attract, 
motivate  and  retain  talent  with  a  focus  on  encouraging  performance,  promoting  accountability  and  adherence  to  Company 
values and alignment with the interests of the Company’s shareholders.

Our  base  pay  program  aims  to  compensate  staff  members  relative  to  the  value  of  the  contributions  of  their  role,  which 
takes into account the skills, knowledge and abilities required to perform each position, as well as the experience brought to the 
job. We also provide annual incentive programs to reward our staff in alignment with achievement of Company-wide goals that 
are established annually and designed to drive aspects of our strategic priorities that support and advance our strategy across our 
Company.  The  majority  of  our  staff  members  are  also  eligible  for  the  grant  of  equity  awards  under  our  long-term  incentive 
program that are designed to align the interests of our staff members with those of our shareholders. For senior level staff, a 
significant proportion of equity award value is based on company performance.

All  staff  also  participate  in  a  regular  performance  measurement  process  through  which  staff  receive  performance  and 
development feedback, and pay is aligned to performance. The Amgen Values and leadership behaviors are an integral part of 
the performance assessments of our staff members, and these evaluations serve as an important information tool and basis for 
compensation decisions.

To support the development of our staff, we provide a variety of programs, including leadership development programs, 
classroom-based  and  virtual  instructor-led  courses,  and  self-paced  learning  options  as  well  as  mentoring,  networking  and 
coaching opportunities.

23

Our  benefit  programs  are  also  generally  broad-based,  promote  health  and  overall  well-being  and  emphasize  saving  for 
retirement. All regular U.S. staff members are eligible to participate in the same core health and welfare and retirement savings 
plans.  Other  U.S.  employee  benefits  include  medical  plans,  dental  plans,  adoption  assistance,  paid  parental  leave  programs, 
access to childcare, employee assistance programs, employee stock purchase plan, flexible spending accounts, life, long-term 
care and business travel accident insurance, short and long-term disability benefits, wellness benefits and work-life resources 
and referrals. Comparable programs and benefits are available globally, with the same health and well-being intent, consistent 
with statutory requirements.

Our Compensation and Management Development Committee provides oversight of our compensation plans, policies and 

programs.

Safety and Wellness and Our Response to the Evolving COVID-19 Pandemic

Creating a safe and healthy workplace for our staff is an important priority at Amgen. Our goal is to have a world class 
safety record through safety leadership, risk management practices and integrating safety throughout our business processes. To 
foster  our  safety  culture,  we  implement  a  comprehensive  safety  program  and  reinforce  desired  safety  behaviors,  driving  to 
understand  and  mitigate  the  root  cause  of  safety  incidents  and  manage  and  control  variability.  We  use  leading  indicators  to 
assess  the  effectiveness  of  our  safety  programs  and  make  course  corrections  as  needed.  Additionally,  we  perform  formal 
executive management review of functional safety performance for Operations, Global Commercial Operations and R&D on a 
quarterly basis with a focus on identifying early signals and taking action to drive continuous improvement. 

In 2022, in response to the evolving requirements of the COVID-19 pandemic, to continue to maintain staff safety while 
enabling greater flexibility for Amgen sites and enhance efficiencies, we began shifting to a decentralized model for COVID-19 
decision-making, empowering our local teams to adjust COVID-19 safety guidance for their individual sites or regions (such as 
the use of masks and other personal protective equipment, occupancy limits, and temperature check and testing, based on local 
regulations and risk assessments of local epidemiology criteria). We will continue to learn and adapt this approach as needed 
for the future.

Our  Corporate  Responsibility  and  Compliance  Committee  provides  general  oversight  of  our  safety  programs  and 

initiatives, while our Board of Directors, as a whole, has overseen our specific responses to the COVID-19 pandemic.

Diversity, Inclusion and Belonging

We believe that a diverse and inclusive culture fosters innovation, which supports our ability to serve patients. Further, we 
also believe our global presence is strengthened by having a workforce that reflects the diversity of the patients we serve. It is 
with these beliefs in mind that we have continued to strengthen and grow our culture of diversity, inclusion and belonging. Our 
Diversity, Inclusion and Belonging Council is led by our executive leadership and is responsible for overseeing our strategy to 
further  a  diverse  and  inclusive  workplace.  We  offer  a  variety  of  diversity,  inclusion  and  belonging  training  and  learning 
programs and have continued to launch enhanced tools and resources that guide staff on the role they play in creating diversity, 
inclusion  and  belonging  throughout  the  organization.  Further,  we  continue  to  incorporate  diversity,  inclusion  and  belonging 
considerations into our business operations, including clinical trial design, procurement and site selection.

Each  of  Amgen’s  Employee  Resource  Groups  is  sponsored  by  senior  executive  leadership.  Our  Employee  Resource 
Groups  promote  leadership,  development  and  belonging  for  members  while  also  working  to  impact  our  business  by  leading 
business initiatives and providing diverse perspectives and experience. In 2022, Amgen launched its newest global Employee 
Resource  Group  called  Recognition  of  Indigenous  Peoples,  Values  and  Environmental  Resources,  or  RIVER,  to  share  and 
continue the traditions, values and culture of Indigenous people.

Building  on  the  successful  adoption  of  our  2021  ESG  goal  under  our  annual  incentive  plan,  we  are  driving  leadership 
ownership and accountability for diversity, inclusion and belonging deeper in the organization with an enhanced ESG goal for 
2022 designed to advance our progress on key ESG initiatives, including by expanding the number of leaders accountable for 
establishing, documenting and executing on diversity, inclusion and belonging action plans.

As  of  December  31,  2022,  women  comprised  over  52%  of  our  global  workforce,  and  ethnic  minorities  accounted  for 
approximately 52% of our U.S. and Puerto Rico-based workforce. In areas of underrepresentation, we develop plans with a goal 
of bringing our representation in line with availability. We engage in outreach efforts to attract, retain and advance more women 
and minorities in our workforce. For example, we have worked to enhance our diverse candidate recruiting pool by developing 
relationships with organizations that can serve as a source of diverse candidates, such as the National Black MBA Association 
and Society of Women in Engineering, as well as historically black colleges and universities. In 2021, a fellowship program 
between  Amgen  and  Howard  University  was  established  to  expand  the  talent  pool  and  diversify  ranks  in  research  and 
development. 

Additionally, we are a founding member of OneTen, a coalition of the world’s largest, best-known companies, that aims 
to  hire  one  million  Black  Americans  (with  a  specific  focus  on  those  without  four-year  college  degrees)  into  good-paying, 
family-sustaining jobs over the next ten years. Amgen is taking a leadership role in the greater Los Angeles region, where the 
company is headquartered, to help expand the coalition of OneTen organizations that share our desire to offer opportunities to 
diverse talent, and we developed an in-house apprenticeship program in support of our OneTen commitment. Other examples of 
actions  that  we  are  taking  in  this  area  include  increased  investment  and  participation  in  the  Healthcare  Businesswomen’s 
Association (a global organization focused on development and business networking for women in healthcare) and the UCLA 
Anderson School of Management leadership advancement programs for women and underrepresented talent.

Item 1A. RISK FACTORS

This  report  and  other  documents  we  file  with  the  SEC  contain  forward-looking  statements  that  are  based  on  current 
expectations,  estimates,  forecasts  and  projections  about  us,  our  future  performance,  our  business,  our  beliefs  and  our 
management’s assumptions. These statements are not guarantees of future performance and involve certain risks, uncertainties 
and assumptions that are difficult to predict. You should carefully consider the risks and uncertainties our business faces. The 
risks described below are not the only ones we face. Our business is also subject to the risks that affect many other companies, 
such as employment relations, general economic conditions, geopolitical events and international operations. Further, additional 
risks not currently known to us or that we currently believe are immaterial may in the future materially and adversely affect our 
business, operations, liquidity and stock price. 

SUMMARY

Risks Related to Economic Conditions and Operating a Global Business, Including During the COVID-19 Pandemic

• The COVID-19 pandemic, and the public and governmental effort to mitigate against the spread of the disease, have had, 
and  are  expected  to  continue  to  have,  an  adverse  effect,  and  may  have  a  material  adverse  effect,  on  our  clinical  trials, 
operations, manufacturing, supply chains, distribution systems, product development, product sales, business and results 
of operations.

• A breakdown of our information technology systems, cyberattack or information security breach could compromise the 
confidentiality, integrity and availability of our information technology systems, network-connected control systems and/
or our data, interrupt the operation of our business and/or affect our reputation.

• Our sales and operations are subject to the risks of doing business internationally, including in emerging markets.

Risks Related to Government Regulations and Third-Party Policies

• Our sales depend on coverage and reimbursement from government and commercial third-party payers, and pricing and 

reimbursement pressures have affected, and are likely to continue to affect, our profitability.

• Guidelines and recommendations published by various organizations can reduce the use of our products.

• The adoption and interpretation of new tax legislation or exposure to additional tax liabilities could affect our profitability.

• Our business may be affected by litigation and government investigations.

Risks Related to Competition

• Our products face substantial competition and our product candidates are also likely to face substantial competition.

27

• Our intellectual property positions may be challenged, invalidated or circumvented, or we may fail to prevail in current 

and future intellectual property litigation. 

• We currently face competition from biosimilars and generics and expect to face increasing competition from biosimilars 

and generics in the future.

• Concentration of sales at certain of our wholesaler distributors and consolidation of private payers may negatively affect 

our business.

Risks Related to Research and Development

• We may not be able to develop commercial products despite significant investments in R&D.

• We  must  conduct  clinical  trials  in  humans  before  we  commercialize  and  sell  any  of  our  product  candidates  or  existing 

products for new indications.

• Our current products and products in development cannot be sold without regulatory approval.

• Some  of  our  products  are  used  with  drug  delivery  or  companion  diagnostic  devices  that  have  their  own  regulatory, 

manufacturing and other risks.

may adversely affect the development and sales of our products.

• Our  efforts  to  collaborate  with  or  acquire  other  companies,  products,  or  technology,  and  to  integrate  the  operations  of 
companies  or  to  support  the  products  or  technology  we  have  acquired,  may  not  be  successful,  and  may  result  in 
unanticipated costs, delays or failures to realize the benefits of the transactions.

Risks Related to Operations

• We perform a substantial majority of our commercial manufacturing activities at our facility in the U.S. territory of Puerto 
Rico  and  a  substantial  majority  of  our  clinical  manufacturing  activities  at  our  facility  in  Thousand  Oaks,  California; 
significant disruptions or production failures at these facilities could significantly impair our ability to supply our products 
or continue our clinical trials.

• We rely on third-party suppliers for certain of our raw materials, medical devices and components.

• Manufacturing difficulties, disruptions or delays could limit supply of our products and limit our product sales.

• Our  business  and  operations  may  be  negatively  affected  by  the  failure,  or  perceived  failure,  of  achieving  our 

environmental, social and governance objectives.

• The effects of global climate change and related natural disasters could negatively affect our business and operations.

General Risk Factors

• Global economic conditions may negatively affect us and may magnify certain risks that affect our business.

• We may not be able to access the capital and credit markets on terms that are favorable to us, or at all.

RISKS  RELATED  TO  ECONOMIC  CONDITIONS  AND  OPERATING  A  GLOBAL  BUSINESS,  INCLUDING 
DURING THE COVID-19 PANDEMIC

The COVID-19 pandemic, and the public and governmental effort to mitigate against the spread of the disease, have had, 
and  are  expected  to  continue  to  have,  an  adverse  effect,  and  may  have  a  material  adverse  effect,  on  our  clinical  trials, 
operations,  manufacturing,  supply  chains,  distribution  systems,  product  development,  product  sales,  business  and  results  of 
operations.

The  novel  coronavirus  identified  in  late  2019,  SARS-CoV-2,  which  causes  the  disease  known  as  COVID-19,  is  an 
ongoing  global  pandemic  that  has  resulted  in  public  and  governmental  efforts  to  contain  or  slow  the  spread  of  the  disease, 
including widespread shelter-in-place orders, social distancing interventions, quarantines, travel restrictions and various forms 
of operational shutdowns. The COVID-19 pandemic and the resulting measures implemented in response to the pandemic are 
adversely  affecting,  and  are  expected  to  continue  to  adversely  affect,  our  business  (including  our  R&D,  clinical  trials, 
operations, manufacturing, supply chains, distribution systems, product development and sales activities), the business activities 

28

of our suppliers, customers, third-party payers and our patients. See Our current products and products in development cannot 
be sold without regulatory approval; see also We must conduct clinical trials in humans before we commercialize and sell any 
of our product candidates or existing products for new indications. Due to the pandemic and these measures and their effects, 
we  have  experienced,  and  expect  to  continue  to  experience,  unpredictable  reductions  in  demand  for  certain  of  our  products, 
exacerbated by COVID-19 surges resulting in repeated shutdowns and/or disruptions in certain geographies.

Federal,  state  and  local,  and  international  governmental  policies  and  initiatives  designed  to  reduce  the  transmission  of 
COVID-19  also  have  resulted  in  the  cancellation  or  delay  of  diagnostic,  elective,  specialty  and  other  procedures  and 
appointments to avoid non-essential patient exposure to medical environments and potential infection with COVID-19 and to 
focus limited resources and personnel capacity toward the treatment of COVID-19. For example, an NPR/Harvard poll in 2021 
found that, with hospitals crowded from COVID-19, one in five U.S. households had to delay care for serious illnesses. These 
measures  and  challenges  will  likely  continue  to  varying  degrees  and  have  significantly  reduced  patient  access  to,  and 
administration of, certain of our drugs. For example, Prolia requires administration by a healthcare provider in doctors’ offices 
or  other  healthcare  settings  that  are  affected  by  COVID-19.  The  U.S.  label  for  Prolia  instructs  healthcare  professionals  who 
discontinue  Prolia  to  transition  the  patient  to  an  alternative  antiresorptive,  including  oral  treatments  that  do  not  require 
administration by a healthcare provider. Further, as a result of COVID-19, oncology patients, in consultation with their doctors, 
may be selecting therapies that are less immunosuppressive or therapies that do not require administration in a hospital setting, 
potentially adversely affecting sales of certain of our products. Also, new patients have been, and are expected to continue to 
be,  less  likely  to  be  diagnosed  and/or  to  start  therapeutics  during  the  pandemic,  and  these  effects,  together  with  the  lower 
treatment  rates  during  the  pandemic,  have  had,  and  are  expected  to  continue  to  have,  a  cumulative  negative  effect  on  the 
commercial performance of our business. The decrease in diagnoses over the course of the pandemic has suppressed the volume 
of new patients starting treatment, which we expect to continue to impact our business. As COVID-19 infection rates ebb and 
flow, we anticipate there could be periodic backlogs of patients seeking appointments with physicians relating to a variety of 
medical conditions, and as a result, patients seeking treatment with certain of our products may have to navigate lower provider 
capacity,  and  this  lower  provider  capacity  could  have  a  continued  adverse  effect  on  our  sales.  Further,  the  effects  of  the 
COVID-19  pandemic  may  result  in  long-term  shifts  in  preferences  among  healthcare  professionals  and  patients  toward 
treatments that do not require administration by healthcare professionals or visits to medical facilities.

As the pandemic continues, and if conditions worsen or if the duration of the pandemic extends significantly, we expect to 
experience additional adverse effects on our development, operational and commercial activities, customer purchases and our 
collections  of  accounts  receivable.  It  remains  uncertain  the  degree  to  which  these  adverse  effects  would  impact  our  future 
operational  and  commercial  activities,  customer  purchases  and  our  collections  as  conditions  begin  to  improve.  There  was  a 
resurgence in COVID-19 infections in numerous jurisdictions in 2022, resulting in the reinstatement of stricter restrictions and 
shutdowns in a number of jurisdictions, including in the United States, Europe and Asia Pacific regions. It is expected that the 
pandemic  will  continue  to  ebb  and  flow,  with  different  jurisdictions  having  higher  levels  of  infections  than  others  over  the 
course of the pandemic. New variants of the SARS-CoV-2 virus have emerged, including the delta and omicron variants and its 
subvariants, and have been shown to be present in many geographies and appear to spread more easily and quickly than other 
variants. Further, although some studies suggest that antibodies generated with currently authorized vaccines may be effective 
against these variants, it remains uncertain whether currently available vaccines will retain their efficacy against future variants 
of the virus. Further, even while vaccine booster shots are available for certain patients, persistent vaccine hesitancy may result 
in  under-vaccinated  populations  which  may  prolong  the  duration  of  the  COVID-19  pandemic  and  continue  to  disrupt  the 
availability of healthcare services to the patients we serve. Jurisdictions may implement, continue or reinstate border closures, 
impose or reimpose prolonged quarantines and further restrict travel and business activity. These measures could significantly 
affect  our  ability  to  support  our  operations  and  customers  and  the  ability  of  our  employees  to  get  to  their  workplaces  to 
discover, study, develop and produce our product candidates and products, disrupt the movement of our products through the 
supply chain, and further prevent or discourage patients from participating in our clinical trials, seeking healthcare services and 
the  administration  of  certain  of  our  products.  The  increased  availability  of  remote  working  arrangements  in  response  to  the 
COVID-19  pandemic  has  expanded  the  pool  of  companies  that  can  compete  for  our  employees  and  employment  candidates. 
Further, in connection with the global outbreak and spread of COVID-19 and in an effort to increase the wider availability of 
needed  medical  products,  we  or  our  suppliers  may  elect  to,  or  governments  may  require  us  or  our  suppliers  to,  allocate 
manufacturing capacity (for example pursuant to the U.S. Defense Production Act) in a way that adversely affects our regular 
operations, customer relationships and financial results. In the United States, on January 21, 2021, President Biden issued an 
Executive  Order  instructing  federal  agencies  to  use  all  available  legal  authorities,  including  the  Defense  Production  Act,  to 
improve current and future pandemic response and biological threat preparedness. The rapid reallocation of resources for the 
treatment  and  prevention  of  COVID-19  (including  the  production  of  COVID-19  vaccines  or  related  therapies,  such  as  our 
agreement to contribute to the production of COVID-19 antibody therapies for Lilly) and/or disruptions and shortages in the 
global supply chain caused by the pandemic, could also result in increased competition for, or reduced availability of, materials 
or components used in the development, manufacturing, distribution or administration of our products. For example, during the 
second  quarter  of  2021,  an  industry-wide  shortage  of  certain  lab  kit  supplies  necessary  for  some  activities  that  support  our 

29

clinical trials has developed that we are actively monitoring and managing. We have also experienced challenges in obtaining 
certain COVID-19-related supplies, including COVID-19 antigen rapid test kits for our staff, as a result of high demand and 
limited supplies during the omicron variant surge. In addition, unpredictable increases in demand for certain of our products 
could exceed our capacity to meet such demand, which could adversely affect our financial results and customer relationships.

The COVID-19 pandemic and the volatile global economic conditions stemming from it may precipitate or amplify the 
other  risks  described  in  this  “Risk  Factors”  section,  which  could  materially  adversely  affect  our  business,  operations  and 
financial condition and results. For example, if a natural disaster or other potentially disruptive event occurs concurrently with 
the COVID-19 pandemic, such disaster or event could deplete our inventory levels and we could experience a disruption to our 
manufacturing or ability to supply our products.

The rapid development and fluidity of the pandemic precludes any prediction as to the ultimate effect of COVID-19 on us. 
The  duration  of  the  measures  being  taken  by  the  authorities  to  mitigate  against  the  spread  of  COVID-19  (including  the 
distribution and/or availability of vaccines and boosters), and the extent to which such measures are effective, if at all, remain 
highly  uncertain.  The  magnitude  and  degree  of  COVID-19’s  adverse  effect  on  our  business  (including  our  product 
development, product sales, operating results and resulting cash flows) and financial condition will be driven by the severity 
and  duration  of  the  pandemic,  the  pandemic’s  effect  on  the  United  States  and  global  economies  and  the  timing,  scope  and 
effectiveness of federal, state, local and international governmental responses to the pandemic. If mitigation of the pandemic 
continues  to  require  further  shelter-in-place  and  shutdown  orders  and/or  restrictions  on  individual  and/or  group  conduct,  any 
adverse  effects  of  the  COVID-19  pandemic  will  likely  grow  and  could  be  enduring,  and  our  business  and  financial  position 
could be materially adversely affected.

A breakdown of our information technology  systems, cyberattack or information security breach could compromise the 
confidentiality, integrity and availability of our information technology systems, network-connected control systems and/or our 
data, interrupt the operation of our business and/or affect our reputation.

To achieve our business objectives, we rely on sophisticated information technology systems, including software, mobile 
applications, cloud services and network-connected control systems, some of which are managed, hosted, provided or serviced 
by  third  parties.  Internal  or  external  events  that  compromise  the  confidentiality,  integrity  and  availability  of  our  systems  and 
data may significantly interrupt the operation of our business, result in significant costs and/or adversely affect our reputation.

Our information technology systems are highly integrated into our business, including our R&D efforts, our clinical and 
commercial  manufacturing  processes  and  our  product  sales  and  distribution  processes.  Further,  as  the  majority  of  our 
employees work remotely for some portion of their jobs in our hybrid work environment, our reliance on our and third-party 
information  technology  systems  has  increased  substantially  and  is  expected  to  continue  to  increase.  The  complexity  and 
interconnected nature of our systems makes them potentially vulnerable to breakdown or other service interruptions. Upgrades 
or changes to our systems or the software that we use may result in the introduction of new cybersecurity vulnerabilities and 
risks. In 2022 we identified a number of security vulnerabilities introduced into our information systems as a result of flaws that 
we  subsequently  identified  in  software  that  we  purchased  and  installed,  and  these  flaws  required  that  we  apply  emergency 
patches to certain of our systems. While we did not experience any significant adverse effects as a result of these vulnerabilities, 
there can be no assurance that we will timely identify and address any future vulnerabilities. Our systems are also subject to 
frequent  perimeter  network  reconnaissance  and  scanning,  phishing  and  other  cyberattacks.  As  the  cyber-threat  landscape 
evolves, these attacks are growing in frequency, sophistication and intensity, and are becoming increasingly difficult to detect. 
Such attacks could include the use of harmful and virulent malware, including ransomware or other denials of service, that can 
be deployed through various means, including the software supply chain, e-mail, malicious websites and/or the use of social 
engineering. We have also experienced denial of service attacks against our network, and although such attacks did not succeed, 
there can be no assurance that our efforts to guard against the wide and growing variety of potential attack techniques will be 
successful  in  the  future.  Attacks  such  as  those  experienced  by  governmental  entities  (including  those  that  approve  and/or 
regulate  our  products,  such  as  the  EMA)  and  other  multi-national  companies,  including  some  of  our  peers,  could  leave  us 
unable to utilize key business systems or access or protect important data and could have a material adverse effect on our ability 
to operate our business, including developing, gaining regulatory approval for, manufacturing, selling and/or distributing our 
products.  For  example,  in  2017,  a  pharmaceutical  company  experienced  a  cyberattack  involving  virulent  malware  that 
significantly disrupted its operations, including its research and sales operations and the production of some of its medicines 
and vaccines. As a result of the cyberattack, its orders and sales for certain products in certain markets were negatively affected. 
In  late  2020,  SolarWinds  Corporation,  a  leading  provider  of  software  for  monitoring  and  managing  information  technology 
infrastructure,  disclosed  that  it  had  suffered  a  cybersecurity  incident  whereby  attackers  had  inserted  malicious  code  into 
legitimate  software  updates  for  its  products  that  were  installed  by  myriad  private  and  government  customers,  enabling  the 
attackers to access a backdoor to such systems. In 2022, Okta, Inc., a provider of software that helps companies manage user 
authentication,  disclosed  that  several  hundred  of  its  corporate  customers  were  vulnerable  to  a  security  breach  that  allowed 

30

attackers to access Okta’s internal network. Although this breach did not have a significant effect on our business, there can be 
no assurance that a similar future breach would not result in a material adverse effect on our business or results of operations.

Our  systems  also  contain  and  utilize  a  high  volume  of  sensitive  data,  including  intellectual  property,  trade  secrets, 
financial  information,  regulatory  information,  strategic  plans,  sales  trends  and  forecasts,  litigation  materials  and/or  personal 
information belonging to us, our staff, our patients, customers and/or other parties. In some cases, we utilize third-party service 
providers to process, store, manage or transmit such data, which may increase our risk. Intentional or inadvertent data privacy 
or  security  breaches  (including  cyberattacks)  resulting  from  attacks  or  lapses  by  employees,  service  providers  (including 
providers  of  information  technology-specific  services),  business  partners,  nation  states  (including  groups  associated  with  or 
supported  by  foreign  intelligence  agencies),  organized  crime  organizations,  “hacktivists”  or  others,  create  risks  that  our 
sensitive  data  may  be  exposed  to  unauthorized  persons,  our  competitors  or  the  public.  System  vulnerabilities  and/or 
cybersecurity breaches experienced by our third-party service providers have constituted a substantial share of the information 
security  risks  that  have  affected  us.  For  example,  in  the  first  half  of  2021,  a  supplier  experienced  a  data  breach  in  which  an 
unauthorized third party acquired access to certain information provided to the supplier in the course of its provision of services 
to  us,  including  business  documents  and  certain  personally  identifiable  patient  information  (not  including  social  security  or 
other financial or health insurance information). As required, we promptly notified the applicable state attorneys general and the 
individuals  whose  personally  identifiable  information  was  affected  of  this  data  breach  at  the  supplier.  In  the  third  quarter  of 
2022,  another  service  provider  experienced  a  similar  cybersecurity  breach  in  which  an  attacker  exfiltrated  certain  data 
(including  non-significant  Amgen  data)  from  the  service  provider’s  systems.  Although  these  supplier  data  breaches  have  not 
resulted in material adverse effects on our business, there can be no assurance that a similar future cybersecurity incident would 
not  result  in  a  material  adverse  effect  on  our  business  or  results  of  operations.  Further,  the  timeliness  of  our  awareness  of  a 
cybersecurity incident affects our ability to respond to and work to mitigate the severity of such events. For example, in 2020 
and 2022, two of our vendors experienced cyberattacks and each initially reported to us that neither event involved our data. 
However,  upon  further  investigation,  they  each  subsequently  informed  us  that  the  attackers  had  accessed  limited,  non-
significant  Amgen  information.  Although  neither  of  these  breaches  had  a  significant  adverse  effect  on  our  business,  in  the 
future we may again not receive timely reporting of cybersecurity events and such events could have a material adverse effect 
on our business.

Cyberattackers  are  also  increasingly  exploiting  vulnerabilities  in  commercially  available  software  from  shared  or  open-
source code. We rely on third party commercial software that may have such vulnerabilities, but as use of open-source code is 
frequently not disclosed, our ability to fully assess this risk to our systems is limited. For example, in December 2021, a remote 
code execution vulnerability was discovered in a widely used software library that is used in a variety of commercially available 
software  and  services.  Although  this  vulnerability  has  not  resulted  in  any  significant  adverse  effects  on  us,  there  can  be  no 
assurances  that  a  similar  future  vulnerability  in  the  software  and  services  that  we  use  would  not  result  in  a  material  adverse 
effect on our business or results of operations. 

Domestic and global government regulators, our business partners, suppliers with whom we do business, companies that 
provide  us  or  our  partners  with  business  services  and  companies  we  have  acquired  or  may  acquire  face  similar  risks,  and 
security breaches of their systems or service outages could adversely affect our security, leave us without access to important 
systems,  products,  raw  materials,  components,  services  or  information  or  expose  our  confidential  data  or  sensitive  personal 
information.  For  example,  in  2019,  two  vendors  that  perform  testing  and  analytical  services  that  we  use  in  developing  and 
manufacturing  our  products  experienced  cyberattacks,  and  in  April  and  September  of  2020,  vendors  that  provide  us  with 
information technology services and clinical data services, respectively, each experienced ransomware attacks. Although there 
was no breach of our systems, each of these incidents required us to disconnect our systems from those vendors’ systems. While 
we  were  able  to  reconnect  our  systems  following  restoration  of  these  vendors’  capabilities  without  significantly  affecting 
product  availability,  a  more  extended  service  outage  affecting  these  or  other  vendors,  particularly  where  such  vendor  is  the 
single source from which we obtain the services, could have a material adverse effect on our business or results of operations. 
In addition, we distribute our products in the United States primarily through three pharmaceutical wholesalers, and a security 
breach that impairs the distribution operations of our wholesalers could significantly impair our ability to deliver our products 
to healthcare providers and patients.

Although  we  have  experienced  system  breakdowns,  attacks  and  information  security  breaches,  we  do  not  believe  such 
breakdowns, attacks and breaches have had a material adverse effect on our business or results of operations. We continue to 
invest in the monitoring, protection and resilience of our critical and/or sensitive data and systems. However, there can be no 
assurances  that  our  efforts  will  detect,  prevent  or  fully  recover  systems  or  data  from  all  breakdowns,  service  interruptions, 
attacks  and/or  breaches  of  our  systems  that  could  adversely  affect  our  business  and  operations  and/or  result  in  the  loss  or 
exposure of critical, proprietary, private, confidential or otherwise sensitive data, which could result in material financial, legal, 
business  or  reputational  harm  to  us  or  negatively  affect  our  stock  price.  While  we  maintain  cyber-liability  insurance,  our 
insurance is not sufficient to cover us against all losses that could potentially result from a service interruption, breach of our 
systems or loss of our critical or sensitive data.

We  are  also  subject  to  various  laws  and  regulations  globally  regarding  privacy  and  data  protection,  including  laws  and 
regulations relating to the collection, storage, handling, use, disclosure, transfer and security of personal data. The legislative 
and regulatory environment regarding privacy and data protection is continuously evolving and developing and the subject of 
significant attention globally. For example, we are subject to the EU’s GDPR, which became effective in May 2018, and the 
CCPA, which became effective in January 2020, both of which provide for substantial penalties for noncompliance. The CCPA 
was  amended  in  late  2020,  to  create  the  California  Privacy  Rights  Act  to  create  opt  in  requirements  for  the  use  of  sensitive 
personal data and the formation of a new dedicated agency for the enforcement of the law, the California Privacy Protection 
Agency.  Virginia,  Colorado,  Utah  and  Connecticut  have  all  subsequently  passed  similar  consumer  privacy  laws,  which  went 
into  effect  in  Virginia  as  of  January  1,  2023,  and  will  go  into  effect  in  Colorado,  Utah  and  Connecticut  later  in  2023.  Other 
jurisdictions  where  we  operate  have  passed,  or  continue  to  propose,  similar  legislation  and/or  regulations.  For  example,  in 
China, the Personal Information Protection Law and the Data Security Law, which regulate data processing activities associated 
with personal and nonpersonal data, are in effect and build upon the existing Cybersecurity Law. Failure to comply with these 
current and future laws could result in significant penalties and reputational harm and could have a material adverse effect on 
our business and results of operations.

Our sales and operations are subject to the risks of doing business internationally, including in emerging markets.

As  we  continue  our  expansion  efforts  in  emerging  markets  around  the  world,  through  acquisitions  and  licensing 
transactions as well as through the development and introduction, both independently and through collaborations such as our 
collaboration with BeiGene, of our products in new markets, we face numerous risks to our business. There is no guarantee that 
our efforts and strategies to expand sales in emerging markets will succeed. Our international business, including in China and 
emerging market countries, may be especially vulnerable to periods of global and local political, legal, regulatory and financial 
instability, including issues of geopolitical relations, the imposition of international sanctions in response to certain state actions 
and/or sovereign debt issues. Further, in 2022 and continuing through early 2023, the Asia Pacific region also experienced a 
surge of COVID-19 infections. While one country in the region initially responded to the surge by activating strict containment 
measures, in late 2022 that country abruptly reversed those measures, resulting in a significant COVID-19 outbreak, causing 
issues such as lack of capacity at hospitals that could lead to a local health emergencies. If relations between the United States 
and other governments deteriorate, our business and investments in such markets may also be adversely affected. We may also 
be  required  to  increase  our  reliance  on  third-party  agents  and  unfamiliar  operations  and  arrangements  including  those 
previously  utilized  by  companies  we  partner  with  or  acquire  in  emerging  markets.  See  We  must  conduct  clinical  trials  in 
humans  before  we  commercialize  and  sell  any  of  our  product  candidates  or  existing  products  for  new  indications.  Our 
expansion efforts in China and emerging markets around the world are dependent upon the establishment of an environment 
that is predictable, navigable and supportive of biopharmaceutical innovation, sustained access for our products and predictable 
pricing  controls.  For  example,  China  continues  to  strengthen  regulations  on  the  collection,  use  and  transmission  of  Chinese 
human  genetic  resources,  and  has  expanded  regulations  on  the  conduct  of  biotechnology  R&D  activities  in  China.  Between 
2020 and 2022, we experienced delays in our applications to the Human Genetic Resources Administration of China that sought 
approval  to  conduct  clinical  trials  in  China.  Our  international  operations  and  business  may  also  be  subject  to  less  protective 
intellectual property or other applicable laws, diverse data privacy and protection requirements, changing tax laws and tariffs, 
trade  restrictions  or  other  barriers  designed  to  protect  industry  in  the  home  country  against  foreign  competition,  far-reaching 
antibribery and anticorruption laws and regulations and/or evolving legal and regulatory environments. 

In  response  to  the  ongoing  armed  conflict  in  Ukraine,  the  U.S.  government,  numerous  state  governments,  the  EU  and 
other  countries  in  which  we  conduct  business  have  imposed  a  wide  range  of  economic  sanctions  that  restrict  commerce  and 
business dealings with Russia, certain regions of Ukraine and certain entities and individuals. This conflict may also precipitate 
or amplify the other risks described herein, including risks relating to cybersecurity, global economic conditions, clinical trials 
and supply chains, which could adversely affect our business, operations and financial condition and results.

As we expand internationally, we are subject to fluctuations in foreign currency exchange rates relative to the U.S. dollar. 
While  we  have  a  program  in  place  that  is  designed  to  reduce  our  exposure  to  foreign  currency  exchange  rate  fluctuations 
through foreign currency hedging arrangements, our hedging efforts do not completely offset the effect of these fluctuations on 
our  revenues  and  earnings.  Overall,  the  legal  and  operational  challenges  of  our  international  business  operations,  along  with 
government controls, the challenges of attracting and retaining qualified personnel and obtaining and/or maintaining necessary 
regulatory  or  pricing  approvals  of  our  products,  may  result  in  material  adverse  effects  on  our  international  product  sales, 
business and results of operations.

RISKS RELATED TO GOVERNMENT REGULATIONS AND THIRD-PARTY POLICIES

Our sales depend on coverage and reimbursement from government and commercial third-party payers, and pricing and 

reimbursement pressures have affected, and are likely to continue to affect, our profitability.

Sales  of  our  products  depend  on  the  availability  and  extent  of  coverage  and  reimbursement  from  third-party  payers, 
including  government  healthcare  programs  and  private  insurance  plans.  Governments  and  private  payers  continue  to  pursue 
initiatives  to  manage  drug  utilization  and  contain  costs.  Further,  pressures  on  healthcare  budgets  from  the  pandemic,  the 
economic  downturn  and  inflation  continue  and  are  likely  to  increase  across  the  markets  we  serve.  Payers  are  increasingly 
focused on costs, which have resulted, and are expected to continue to result, in lower reimbursement rates for our products or 
narrower  populations  for  which  payers  will  reimburse.  Continued  intense  public  scrutiny  of  the  price  of  drugs  and  other 
healthcare costs, together with payer dynamics, have limited, and are likely to continue to limit, our ability to set or adjust the 
price  of  our  products  based  on  their  value,  which  can  have  a  material  adverse  effect  on  our  business.  In  the  United  States, 
particularly over the past few years, a number of legislative and regulatory proposals have been introduced and/or signed into 
law that attempt to lower drug prices. These include legislation promulgated by the IRA that enables the U.S. government to set 
prices for certain drugs in Medicare, redesigns Medicare Part D benefits to shift a greater portion of the costs to manufacturers 
and  enables  the  U.S.  government  to  impose  penalties  if  drug  prices  are  increased  at  a  rate  faster  than  inflation.  Additional 
proposals  focused  on  drug  pricing  continue  to  be  debated,  and  additional  executive  orders  focused  on  drug  pricing  and 
competition are likely to be adopted and implemented in some form. Government actions or ballot initiatives at the state level 
also  represent  a  highly  active  area  of  policymaking  and  experimentation,  including  pursuit  of  proposals  that  limit  drug 
reimbursement under state run Medicaid programs based on reference prices or permitting importation of drugs from Canada. 
Such state policies may also eventually be adopted at the federal level.

We are unable to predict which or how many policy, regulatory, administrative or legislative changes may ultimately be, 
or effectively estimate the consequences to our business if, enacted and implemented. However, to the extent that payer actions 
further decrease or modify the coverage or reimbursement available for our products, require that we pay increased rebates or 
shift other costs to us, limit or affect our decisions regarding the pricing of or otherwise reduce the use of our products, such 
actions could have a material adverse effect on our business and results of operations.

—Changing U.S. federal coverage and reimbursement policies and practices have affected and are likely to continue to 

affect access to, pricing of and sales of our products

A  substantial  portion  of  our  U.S.  business  relies  on  reimbursement  from  federal  government  healthcare  programs  and 
commercial  insurance  plans  regulated  by  federal  and  state  governments.  See  Part  I,  Item  1.  Business—Reimbursement.  Our 
business  has  been  and  will  continue  to  be  affected  by  legislative  actions  changing  U.S.  federal  reimbursement  policy.  For 
example, in August 2022, the IRA was enacted and includes provisions requiring that: (1) beginning in 2026, mandatory price 
setting be introduced in Medicare for certain drugs paid for under Parts B and D, whereby manufacturers must accept a price 
established by the government or face penalties on all U.S. sales (starting with 10 drugs in 2026, adding 15 in 2027 and 2028, 
and adding 20 in 2029 and subsequent years such that by 2031 approximately 100 drugs could be subject to such set prices); (2) 
starting in 2024, Medicare Part D be redesigned to cap beneficiary out-of-pocket costs and, beginning January 1, 2025, Federal 
reinsurance  be  reduced  in  the  catastrophic  phase  (resulting  in  a  shift  and  increase  of  such  costs  to  Part  D  plans  and 
manufacturers,  including  by  requiring  manufacturer  discounts  on  certain  drugs);  and  (3)  beginning  October  1,  2022, 
manufacturers will owe rebates on drugs reimbursed under Medicare Part D if price increases outpace inflation, and beginning 
January 1, 2023, will owe rebates on drugs reimbursed under Medicare Part B if price increases outpace inflation. The IRA’s 
drug pricing controls and Medicare redesign is likely to have a material adverse effect on our sales (particularly for our products 
that  are  more  substantially  reliant  on  Medicare  reimbursement),  our  business  and  our  results  of  operations.  However,  as  the 
degree  of  impact  from  this  legislation  on  our  business  depends  on  a  number  of  implementation  decisions,  the  extent  of  the 
IRA’s  impact  on  our  sales  and,  in  turn,  our  business  remains  unclear.  Further,  following  the  passage  of  the  IRA,  the 
environment remains dynamic, and in October 2022, the Administration issued an Executive Order on Lowering Prescription 
Drug Costs for Americans that calls for the HHS to issue a report within 90 days on Innovation Center models that would lower 
drug  costs  and  promote  access  to  innovative  drug  therapies  for  Medicare  and  Medicaid  beneficiaries.  This  Executive  Order 
follows a 2021 Executive Order that included a timeline designed to increase competition in the healthcare sector, including by 
calling for the FDA to develop prescription drug importation programs and the FTC to apply greater scrutiny of anticompetitive 
activity.  Responses  to  this  order,  including  by  the  HHS,  which  released  a  report  with  drug  pricing  proposals  that  seek  to 
promote  competition,  and  by  the  USPTO,  which  has  taken  steps  to  strengthen  coordination  with  the  FDA  to  address 
impediments  to  generic  drug  and  biosimilar  competition.  CMS  policy  changes  and  demonstration  projects  to  test  new  care, 
delivery and payment models can also significantly affect how drugs, including our products, are covered and reimbursed. In 
September  2021,  HHS  released  a  plan  to  address  drug  pricing  that  included  potential  future  mandatory  models  that  link 
payment for prescription drugs and biologics to certain factors, including the overall cost of care.

33

We also face risks related to the reporting of pricing data that affects reimbursement of and discounts provided for our 
products. U.S. government price reporting regulations are complex and may require biopharmaceutical manufacturers to update 
certain previously submitted data. If our submitted pricing data are incorrect, we may become subject to substantial fines and 
penalties or other government enforcement actions, which could have a material adverse effect on our business and results of 
operations. In addition, as a result of restating previously reported price data, we may be required to pay additional rebates and 
provide additional discounts. 

—Changing reimbursement and pricing actions in various states have negatively affected and may continue to negatively 

affect access to and have affected and may continue to affect sales of our products

At the state level, government actions or ballot initiatives can also affect how our products are covered and reimbursed 
and/or create additional pressure on our pricing decisions. Existing and proposed state pricing laws have added complexity to 
the pricing of drugs and may already be affecting industry pricing decisions. A number of states have adopted, and many other 
states  are  considering,  drug  importation  programs  or  other  pricing  actions,  including  proposals  designed  to  require 
biopharmaceutical manufacturers to report to the state proprietary pricing information or provide advance notice of certain price 
increases.  For  example,  a  California  law  requires  biopharmaceutical  manufacturers  to  notify  health  insurers  and  government 
health plans at least 60 days before scheduled prescription drug price increases that exceed certain thresholds. Similar laws exist 
in Oregon and Washington. Additional proposals directed at Medicaid seek to penalize manufacturers for pricing drugs above a 
certain threshold or limit spending on biopharmaceutical products. States are also seeking to change the way they pay for drugs 
for  patients  covered  by  state  programs.  New  York  has  established  a  Medicaid  drug  spending  cap,  and  Massachusetts 
implemented  a  new  review  and  supplemental  rebate  negotiation  process.  Six  states  (Colorado,  Maine,  New  Hampshire, 
Maryland, Oregon and Washington) have enacted laws that establish Prescription Drug Affordability Boards (PDABs) to study 
drug  prices  and  identify  drugs  that  pose  affordability  challenges,  and  in  three  states  (Colorado,  Maryland  and  Washington) 
include  authority  for  the  state  PDAB  to  set  upper  payment  limits  on  certain  drugs  in  state  regulated  plans.  Other  states  may 
consider implementing similar policies and laws. Additionally, Colorado, Florida, Maine, New Hampshire, New Mexico and 
Vermont have enacted laws, and several other states have proposed bills, to implement importation of drugs from Canada. The 
FDA  has  met  with  representatives  from  Colorado,  Florida,  Maine  and  New  Mexico  to  discuss  those  states’  proposed 
importation programs, and the FDA may be working towards approving such plans. Other states could adopt similar approaches 
or  could  pursue  different  policy  changes  in  a  continuing  effort  to  reduce  their  costs.  Ultimately,  as  with  U.S.  federal 
government actions, existing or future state government actions or ballot initiatives may also have a material adverse effect on 
our product sales, business and results of operations.

—U.S. commercial payer actions have affected and may continue to affect access to and sales of our products 

Payers,  including  healthcare  insurers,  PBMs,  integrated  healthcare  delivery  systems  (vertically-integrated  organizations 
built  from  consolidations  of  healthcare  insurers  and  PBMs)  and  group  purchasing  organizations,  increasingly  seek  ways  to 
reduce their costs. With increasing frequency, payers are adopting benefit plan changes that shift a greater proportion of drug 
costs  to  patients.  Such  measures  include  more  limited  benefit  plan  designs,  high  deductible  plans,  higher  patient  co-pay  or 
coinsurance  obligations  and  more  significant  limitations  on  patients’  use  of  manufacturer  commercial  co-pay  assistance 
programs. Further, government regulation of payers may affect these trends. For example, CMS finalized a policy for plan years 
starting on or after January 1, 2021 that has caused commercial payers to more widely adopt co-pay accumulator adjustment 
programs.  Payers,  including  PBMs,  have  sought,  and  continue  to  seek,  price  discounts  or  rebates  in  connection  with  the 
placement of our products on their formularies or those they manage, and to also impose restrictions on access to or usage of 
our products (such as Step Therapy), require that patients receive the payer’s prior authorization before covering the product, 
and/or chosen to exclude certain indications for which our products are approved. For example, some payers require physicians 
to  demonstrate  or  document  that  the  patients  for  whom  Repatha  has  been  prescribed  meet  their  utilization  criteria,  and  these 
requirements have served to limit and may continue to limit patient access to Repatha treatment. In an effort to reduce barriers 
to  access,  we  reduced  the  net  price  of  Repatha  by  providing  greater  discounts  and  rebates  to  payers  (including  PBMs  that 
administer  Medicare  Part  D  prescription  drug  plans),  and  in  response  to  a  very  high  percentage  of  Medicare  patients 
abandoning  their  Repatha  prescriptions  rather  than  paying  their  co-pay,  we  introduced  a  set  of  new  National  Drug  Codes  to 
make Repatha available at a lower list price. However, affordability of patient out-of-pocket co-pay cost has limited and may 
continue to limit patient use. Further, despite these net and list price reductions, some payers have restricted, and may continue 
to restrict, patient access and may seek further discounts or rebates or take other actions, such as changing formulary coverage 
for Repatha, that could reduce our sales of Repatha. These factors have limited, and may continue to limit, patient affordability 
and use, negatively affecting Repatha sales.

Further, significant consolidation in the health insurance industry has resulted in a few large insurers and PBMs, which 
places  greater  pressure  on  pricing  and  usage  negotiations  with  biopharmaceutical  manufacturers,  significantly  increasing 
discount and rebate requirements and limiting patient access and usage. For example, in the United States, as of the beginning 
of 2023, the top five integrated health plans and PBMs controlled about 92% of all pharmacy prescriptions. This high degree of 

34

consolidation among insurers and PBMs and other payers, including through integrated healthcare delivery systems and/or with 
specialty or mail-order pharmacies and pharmacy retailers, has increased the negotiating leverage such entities have over us and 
other  biopharmaceutical  manufacturers  and  has  resulted  in  greater  price  discounts,  rebates  and  service  fees  realized  by  those 
payers from our business. Each of CVS, Express Scripts and United Health Group (among the top five integrated health plans 
and  PBMs),  each  have  Rebate  Management  Organizations  that  further  increase  their  leverage  to  negotiate  deeper  discounts. 
Ultimately,  additional  discounts,  rebates,  fees,  coverage  changes,  plan  changes,  restrictions  or  exclusions  imposed  by  these 
commercial payers could have a material adverse effect on our product sales, business and results of operations. Policy reforms 
advanced  by  Congress  or  the  Administration  that  refine  the  role  of  PBMs  in  the  U.S.  marketplace  could  have  downstream 
implications or consequences for our business and how we interact with these entities. For example, on June 7, 2022, the FTC 
launched an inquiry into the business practices of PBMs, and the results of such inquiry could have an effect on manufacturer 
interactions with PBMs, resulting in changes to access for certain medicines. See our —Concentration of sales at certain of our 
wholesaler distributors and consolidation of private payers may negatively affect our business.

Our  business  is  also  affected  by  policies  implemented  by  private  healthcare  entities  that  process  Medicare  claims, 
including Medicare Administrative Contractors. For example, in the second quarter of 2022, several Medicare Administrative 
Contractors issued notice, in contravention of TEZSPIRE’s FDA approved labeling, that TEZSPIRE would be added to their 
“self-administered drug” exclusion lists. Although the Medicare Administrative Contractors subsequently removed TEZSPIRE 
from  their  exclusion  lists,  these  exclusions,  if  reintroduced  and/or  implemented,  would  result  in  Medicare  beneficiaries  with 
severe asthma losing access to TEZSPIRE coverage under Medicare Part B and potentially also under Medicare Advantage.

—Government and commercial payer actions outside the United States have affected and will continue to affect access to 

and sales of our products

Outside the United States, we expect countries will also continue to take actions to reduce their drug expenditures. See 
Part  I,  Item  1.  Business—Reimbursement.  Pressures  to  decrease  drug  expenditures  may  further  intensify  as  the  COVID-19 
pandemic  has  strained  government  budgets  and  as  economic  conditions  continue  to  worsen  in  certain  regions,  including  in 
Europe where high inflation and the energy crisis relating to the Russia–Ukraine conflict are challenging the economies in that 
region. International reference pricing has been widely used by many countries outside the United States to control costs based 
on an external benchmark of a product’s price in other countries. International reference pricing policies can change quickly and 
frequently and may not reflect differences in the burden of disease, indications, market structures or affordability differences 
across  countries  or  regions.  Other  expenditure  control  practices,  including  but  not  limited  to  the  use  of  revenue  clawbacks, 
rebates  and  percentage  caps  on  price  increases,  are  used  in  various  foreign  jurisdictions  as  well.  In  addition,  countries  may 
refuse to reimburse or may restrict the reimbursed population for a product when their national health technology assessments 
do  not  consider  a  medicine  to  demonstrate  sufficient  clinical  benefit  beyond  existing  therapies  or  to  meet  certain  cost 
effectiveness  thresholds.  For  example,  despite  the  EMA’s  approval  of  Repatha  for  the  treatment  of  patients  with  established 
atherosclerotic  disease,  prior  to  2020,  the  reimbursement  of  Repatha  in  France  was  limited  to  a  narrower  patient  population 
(such  as  those  with  homozygous  familial  hypercholesterolemia  (HoFH))  following  a  national  health  technology  assessment. 
Many  countries  decide  on  reimbursement  between  potentially  competing  products  through  national  or  regional  tenders  that 
often  result  in  one  product  receiving  most  or  all  of  the  sales  in  that  country  or  region.  Failure  to  obtain  coverage  and 
reimbursement for our products, a deterioration in their existing coverage and reimbursement or a decline in the timeliness or 
certainty of payment by payers to physicians and other providers has negatively affected, and may further negatively affect, the 
ability or willingness of healthcare providers to prescribe our products for their patients and otherwise negatively affect the use 
of our products or the prices we realize for them. Such changes have had, and could in the future have, a material adverse effect 
on our product sales, business and results of operations.

Guidelines and recommendations published by various organizations can reduce the use of our products.

Government  agencies  promulgate  regulations  and  guidelines  directly  applicable  to  us  and  to  our  products.  Professional 
societies,  practice  management  groups,  insurance  carriers,  physicians’  groups,  private  health  and  science  foundations  and 
organizations involved in various diseases also publish guidelines and recommendations to healthcare providers, administrators 
and payers, as well as patient communities. Recommendations by government agencies or other groups and organizations may 
relate to such matters as usage, dosage, route of administration and use of related therapies. In addition, a growing number of 
organizations are providing assessments of the value and pricing of biopharmaceutical products, and even organizations whose 
guidelines  have  historically  been  focused  on  clinical  matters  have  begun  to  incorporate  analyses  of  the  cost  effectiveness  of 
various  treatments  into  their  treatment  guidelines  and  recommendations.  Value  assessments  may  come  from  private 
organizations that publish their findings and offer recommendations relating to the products’ reimbursement by government and 
private payers. Some companies and payers have announced pricing and payment decisions based in part on the assessments of 
private  organizations.  In  addition,  government  health  technology  assessment  organizations  in  many  countries  make 
reimbursement  recommendations  to  payers  in  their  jurisdictions  based  on  the  clinical  effectiveness,  cost-effectiveness  and 
service effects of new, emerging and existing medicines and treatments. Such health technology assessment organizations have 

35

recommended, and may in the future recommend, reimbursement for certain of our products for a narrower indication than was 
approved  by  applicable  regulatory  agencies  or  may  recommend  against  reimbursement  entirely.  See  Our  sales  depend  on 
coverage and reimbursement from government and commercial third-party payers, and pricing and reimbursement pressures 
have  affected,  and  are  likely  to  continue  to  affect,  our  profitability.  Such  recommendations  or  guidelines  may  affect  our 
reputation, and any recommendations or guidelines that result in decreased use, dosage or reimbursement of our products could 
have  a  material  adverse  effect  on  our  product  sales,  business  and  results  of  operations.  In  addition,  the  perception  by  the 
investment community or stockholders that such recommendations or guidelines will result in decreased use and dosage of our 
products could adversely affect the market price of our common stock.

The  adoption  and  interpretation  of  new  tax  legislation  or  exposure  to  additional  tax  liabilities  could  affect  our 

profitability.

We are subject to income and other taxes in the United States and other jurisdictions in which we do business. As a result, 
our  provision  for  income  taxes  is  derived  from  a  combination  of  applicable  tax  rates  in  the  various  places  we  operate. 
Significant judgment is required for determining our provision for income tax.

One or more of our legal entities file income tax returns in the U.S. federal jurisdiction, various U.S. state jurisdictions 
and  certain  foreign  jurisdictions.  Our  income  tax  returns  are  routinely  examined  by  tax  authorities  in  those  jurisdictions. 
Significant disputes can and have arisen with tax authorities involving issues regarding the timing and amount of deductions, 
the  use  of  tax  credits  and  allocations  of  income  and  expenses  among  various  tax  jurisdictions  because  of  differing 
interpretations  of  tax  laws,  regulations  and  relevant  facts,  and  such  tax  authorities  (including  the  IRS)  are  becoming  more 
aggressive in their audits and are particularly focused on such matters. In 2017, we received an RAR and a modified RAR from 
the  IRS  for  the  years  2010–2012,  proposing  significant  adjustments  that  primarily  relate  to  the  allocation  of  profits  between 
certain of our entities in the United States and the U.S. territory of Puerto Rico. We disagreed with the proposed adjustments 
and calculations and pursued resolution with the IRS administrative appeals office but were unable to reach resolution. In July 
2021, we filed a petition in the U.S. Tax Court to contest two duplicate Statutory Notices of Deficiency (Notices) for the years 
2010–2012 that we received in May and July 2021 which seek to increase our U.S. taxable income for the years 2010–2012. 

In  2020,  we  received  an  RAR  and  a  modified  RAR  from  the  IRS  for  the  years  2013–2015,  also  proposing  significant 
adjustments  that  primarily  relate  to  the  allocation  of  profits  between  certain  of  our  entities  in  the  United  States  and  the  U.S. 
territory of Puerto Rico similar to those proposed for the years 2010–2012. We disagreed with the proposed adjustments and 
calculations and pursued resolution with the IRS appeals office but were unable to reach resolution. In July 2022, we filed a 
petition in the U.S. Tax Court to contest a Notice for the years 2013–2015 that we previously reported receiving in April 2022 
that seeks to increase our U.S. taxable income for the years 2013–2015 and asserts penalties.

We firmly believe that the IRS positions set forth in the 2010–2012 and 2013–2015 Notices are without merit. We are 
contesting the 2010–2012 and 2013–2015 Notices through the judicial process. The cases were consolidated on December 19, 
2022. 

We are currently also under examination by the IRS for the years 2016–2018 with respect to issues similar to those for the 

2010 through 2015 period. In addition, we are under examination by a number of state and foreign tax jurisdictions.

Final resolution of these complex tax matters is not likely within the next 12 months. We continue to believe our accrual 
for income tax liabilities is appropriate based on past experience, interpretations of tax law, application of the tax law to our 
facts and judgments about potential actions by tax authorities; however, due to the complexity of the provision for income taxes 
and uncertain resolution of these matters, the ultimate outcome of any tax matters may result in payments substantially greater 
than amounts accrued and could have a material adverse effect on the results of our operations. 

See Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of 

Operations, Income Taxes, and Part IV—Note 6, Income taxes, to the Consolidated Financial Statements.

Our  provision  for  income  taxes  and  results  of  operations  in  the  future  could  be  adversely  affected  by  changes  to  our 
operating structure, changes in the mix of income and expenses in countries with differing tax rates, changes in the valuation of 
deferred tax assets and liabilities and changes in applicable tax laws, regulations or administrative interpretations thereof. The 
2017  Tax  Act  is  complex  and  a  large  volume  of  regulations  and  guidance  has  been  issued  and  could  be  subject  to  different 
interpretations. We could face audit challenges to our application of the 2017 Tax Act. In addition, there are several upcoming 
provisions in the 2017 Tax Act, including increases in the tax rates on foreign earnings and export income scheduled to take 
effect at the end of 2025, that could result in an increase in our effective tax rate. 

The  Administration  and  Congress  continue  to  discuss  changes  to  existing  tax  law  that  could  substantially  increase  the 
taxes we pay in the United States. Further, the OECD reached an agreement to align countries on a minimum corporate tax rate 
and an expansion of the taxing rights of market countries. Some individual countries, including those in the EU, have proposed 

36

legislation  to  implement  the  global  minimum  tax  agreement.  In  other  countries  such  as  the  United  States,  however,  the 
implementation of the OECD agreement remains highly uncertain. If enacted, either by all OECD participants or unilaterally by 
individual countries, the agreement could result in tax increases or double taxation that could affect our United States or foreign 
tax liabilities. Changes to existing tax law in the United States, the U.S. territory of Puerto Rico or other jurisdictions, including 
the  changes  and  potential  changes  discussed  above,  could  result  in  tax  increases  where  we  do  business  and  could  have  a 
material adverse effect on the results of our operations.

Our business may be affected by litigation and government investigations.

We  and  certain  of  our  subsidiaries  are  involved  in  legal  proceedings.  See  Part  IV—Note  19,  Contingencies  and 
commitments,  to  the  Consolidated  Financial  Statements.  Civil  and  criminal  litigation  is  inherently  unpredictable,  and  the 
outcome can result in costly verdicts, fines and penalties, exclusion from federal healthcare programs and/or injunctive relief 
that affect how we operate our business. Defense of litigation claims can be expensive, time consuming and distracting, and it is 
possible that we could incur judgments or enter into settlements of claims for monetary damages or change the way we operate 
our business, which could have a material adverse effect on our product sales, business and results of operations. In addition, 
product liability is a major risk in testing and marketing biotechnology and pharmaceutical products. We may face substantial 
product liability exposure in human clinical trials and for products we sell after regulatory approval. Product liability claims, 
regardless of their merits, could be costly and divert management’s attention and could adversely affect our reputation and the 
demand  for  our  products.  We  and  certain  of  our  subsidiaries  have  previously  been  named  as  defendants  in  product  liability 
actions for certain of our products.

We are also involved in government investigations that arise in the ordinary course of our business. In recent years, 
there has been a trend of increasing government investigations and litigations against companies operating in our industry, both 
in  the  United  States  and  around  the  world.  See  Our  sales  depend  on  coverage  and  reimbursement  from  government  and 
commercial third-party payers, and pricing and reimbursement pressures have affected, and are likely to continue to affect, our 
profitability.  Our  business  activities  outside  of  the  United  States  are  subject  to  the  FCPA  and  similar  antibribery  or 
anticorruption  laws,  regulations  or  rules  of  other  countries  in  which  we  operate,  including  the  U.K.  Bribery  Act.  We  cannot 
ensure that all our employees, agents, contractors, vendors, licensees, partners or collaborators will comply with all applicable 
laws and regulations. On April 25, 2019, we entered into a settlement agreement with the DOJ and the OIG of the HHS to settle 
certain allegations relating to our support of independent charitable organizations that provide patients with financial assistance 
to access their medicines. As a result, we entered into a corporate integrity agreement with the OIG that requires us to maintain 
a  corporate  compliance  program  and  to  undertake  a  set  of  defined  corporate  integrity  obligations  for  a  period  of  five  years. 
While we expect to fully comply with all of our obligations under the corporate integrity agreement, failure to do so could result 
in  substantial  penalties  and  potential  exclusion  from  government  healthcare  programs.  We  may  also  see  new  government 
investigations of or actions against us citing novel theories of recovery. For example, prosecutors are placing greater scrutiny on 
patient support programs, including commercial copay assistance programs, and further enforcement actions and investigations 
regarding such programs could limit our ability to provide co-pay assistance to commercial patients. Greater scrutiny has also 
been placed on sponsorships, speaker programs and other arrangements where healthcare professionals receive remuneration, 
travel or other value to participate in certain events, and further enforcement actions could limit our ability to participate in such 
arrangements. Any of these results could have a material adverse effect on our business and results of operations.

RISKS RELATED TO COMPETITION

Our products face substantial competition and our product candidates are also likely to face substantial competition.

We operate in a highly competitive environment. See Item 1. Business—Marketing, Distribution and Selected Marketed 
Products—Competition.  We  expect  that  our  products  and  product  candidates  will  compete  with  existing  drugs,  new  drugs 
currently in development, drugs currently approved for other indications that may later be approved for the same indications as 
those  of  our  products  and  drugs  approved  for  other  indications  that  are  used  off-label.  Large  pharmaceutical  companies  and 
generics  manufacturers  of  pharmaceutical  products  have  expanded  into,  and  are  expected  to  continue  expanding  into,  the 
biotechnology  field,  and  some  pharmaceutical  companies  and  generics  manufacturers  have  formed  partnerships  to  pursue 
biosimilars. With the proliferation of companies pursuing biopharmaceuticals, several of our biosimilar products have entered, 
and a number of our product candidates may enter, markets with one or more competitors or with competitors soon to arrive. In 
addition,  some  of  our  competitors  may  have  technical,  competitive  or  other  advantages  over  us  for  the  development  of 
technologies and processes or greater experience in particular therapeutic areas, and consolidation among pharmaceutical and 
biotechnology companies can enhance such advantages. These advantages may make it difficult for us to compete with them 
successfully to discover, develop and market new products and for our current products to compete with new products or new 
product indications they may bring to market. As a result, our products have been competing and may continue to compete, and 
our product candidates may compete, against products or product candidates that offer higher rebates or discounts, lower prices, 
equivalent  or  superior  efficacy,  better  safety  profiles,  easier  administration,  earlier  market  availability  or  other  competitive 

37

features. If we are unable to compete effectively, this could reduce our sales, which could have a material adverse effect on our 
business and results of operations.

Our intellectual property positions may be challenged, invalidated or circumvented, or we may fail to prevail in current 

and future intellectual property litigation.

Our success depends in part on our ability to obtain and defend patent rights and other intellectual property rights that are 
important  to  the  commercialization  of  our  products  and  product  candidates.  The  patent  positions  of  pharmaceutical  and 
biotechnology companies can be highly uncertain and often involve complex legal, scientific and factual questions. Driven by 
cost  pressures,  efforts  to  limit  or  weaken  patent  protection  for  our  industry  are  increasing.  For  example,  the  COVID-19 
pandemic has resulted in increased interest in compulsory licenses, march-in rights or other governmental interventions, both in 
the United States and internationally, related to the procurement of drugs, and the World Trade Organization has agreed to a 
waiver  of  COVID-19  vaccine  intellectual  property  protections  through  the  Trade-Related  Aspects  of  Intellectual  Property 
Rights waiver process. See The COVID-19 pandemic, and the public and governmental effort to mitigate against the spread of 
the disease, have had, and are expected to continue to have, an adverse effect, and may have a material adverse effect, on our 
clinical  trials,  operations,  manufacturing,  supply  chains,  distribution  systems,  product  development,  product  sales,  business 
and results of operations. Third parties have challenged and may continue to challenge, invalidate or circumvent our patents 
and  patent  applications  relating  to  our  products,  product  candidates  and  technologies.  Challenges  to  patents  may  come  from 
potential  competitors  or  from  parties  other  than  those  who  seek  to  market  a  potentially-infringing  product.  In  addition,  our 
patent positions might not protect us against competitors with similar products or technologies because competing products or 
technologies  may  not  infringe  our  patents.  For  certain  of  our  product  candidates,  there  are  third  parties  who  have  patents  or 
pending  patent  applications  that  they  may  claim  necessitate  payment  of  a  royalty  or  prevent  us  from  commercializing  these 
product  candidates  in  certain  territories.  Patent  disputes  are  frequent,  costly  and  can  preclude,  delay  or  increase  the  cost  of 
commercialization  of  products.  We  have  been  in  the  past,  are  currently  and  expect  to  be  in  the  future,  involved  in  patent 
litigation. These matters have included, and may in the future include, litigation with manufacturers of products that purport to 
be biosimilars of certain of our products for patent infringement and for failure to comply with certain provisions of the BPCIA. 
A determination made by a court, agency or tribunal concerning infringement, validity, enforceability, injunctive or economic 
remedy, or the right to patent protection, for example, are typically subject to appellate or administrative review. Upon review, 
such initial determinations may be afforded little or no deference by the reviewing tribunal and may be affirmed, reversed or 
made the subject of reconsideration through further proceedings. A patent dispute or litigation has not discouraged, and may not 
in the future discourage, a potential violator from bringing the allegedly infringing product to market prior to a final resolution 
of  the  dispute  or  litigation.  The  period  from  inception  until  resolution  of  a  patent  dispute  or  litigation  is  subject  to  the 
availability and schedule of the court, agency or tribunal before which the dispute or litigation is pending. We have been, and 
may in the future be, subject to competition during this period and may not be able to recover fully from the losses, damages 
and harms we incur from infringement by the competitor product even if we prevail. Moreover, if we lose or settle current or 
future  litigations  at  certain  stages  or  entirely,  we  could  be  subject  to  competition  and/or  significant  liabilities,  be  required  to 
enter into third-party licenses for the infringed product or technology or be required to cease using the technology or product in 
dispute. In addition, we cannot guarantee that such licenses will be available on terms acceptable to us, or at all.

Further, under the Hatch–Waxman Act, our products approved by the FDA under the FDCA have been, and may in the 
future  be,  the  subject  of  patent  litigation  with  generics  competitors  before  expiry  of  the  five-year  period  of  data  exclusivity 
provided  for  under  the  Hatch-Waxman  Act  and  prior  to  the  expiration  of  the  patents  listed  for  the  product.  Likewise,  our 
innovative biologic products have been, and may in the future be, the subject of patent litigation prior to the expiration of our 
patents and, with respect to competitors seeking approval as a biosimilar or interchangeable version of our products, prior to the 
12-year exclusivity period provided under the BPCIA. In addition, we have faced, and may in the future face, patent litigation 
involving  claims  that  the  biosimilar  product  candidates  we  are  working  to  develop  infringe  the  patents  of  other  companies, 
including  those  that  manufacture,  market  or  sell  the  applicable  reference  products  or  who  are  developing  or  have  developed 
other biosimilar versions of such products. Alternatively, patents held by other entities have contributed, and may in the future 
contribute, to a decision by us to not pursue all of the same labeled indications as are held by these companies. While we have 
attempted, and expect to continue to attempt, to challenge the patents held by other companies, our efforts may be unsuccessful. 
For examples of and information related to our patent litigation, see Part IV—Note 19, Contingencies and commitments, to the 
Consolidated Financial Statements.

Certain  of  the  existing  patents  on  our  products  have  expired  or  will  soon  expire.  See  Item  1.  Business—Marketing, 
Distribution  and  Selected  Marketed  Products—Patents.  As  our  patents  expire,  competitors  are  able  to  legally  produce  and 
market  similar  products  or  technologies,  including  biosimilars,  which  has  had,  and  may  continue  to  have,  a  material  adverse 
effect on our product sales, business and results of operations. In addition, competitors have been, and may continue to be, able 
to invalidate, design around or otherwise circumvent our patents and sell competing products.

38

We currently face competition from biosimilars and generics and expect to face increasing competition from biosimilars 

and generics in the future.

We currently face competition from biosimilars and generics in most of the territories in which we operate, including the 
United  States  and  Europe,  and  we  expect  to  face  increasing  biosimilar  and/or  generics  competition  this  year  and  beyond. 
Expiration or successful challenge of applicable patent rights or expiration of an applicable exclusivity period has accelerated 
such competition, and we expect to face more litigation regarding the validity and/or scope of our patents. Our products have 
also experienced greater competition from lower cost biosimilars or generics that come to market when branded products that 
compete with our products lose their own patent protection. To the extent that governments adopt more permissive regulatory 
approval standards and competitors are able to obtain broader or expedited marketing approval for biosimilars and generics, the 
rate of increased competition for our products could accelerate.

In  the  EU,  biosimilars  are  evaluated  for  marketing  authorization  pursuant  to  a  set  of  general  and  product  class-specific 
guidelines. In addition, in an effort to spur biosimilar utilization and/or increase potential healthcare savings, some EU countries 
and some Canadian provinces have adopted, or are considering the adoption of, biosimilar uptake measures such as physician 
prescribing  quotas  or  automatic  pharmacy  substitution  of  biosimilars  for  the  corresponding  reference  products.  Some  EU 
countries impose automatic price reductions upon market entry of one or more biosimilar competitors. In September 2022, the 
EMA and the EU Heads of Medicines’ Agencies (HMA) issued a joint statement providing that biosimilar medicines approved 
in the EU are “interchangeable” with their reference products and other biosimilars of the same reference product. This EMA-
HMA  statement  could  further  contribute  to  the  prescribing  of  biosimilars  and  to  greater  competition  in  Europe.  While  the 
degree  of  competitive  effects  of  biosimilar  competition  differs  between  EU  countries  and  between  products,  in  the  EU  the 
overall  use  of  biosimilars  and  the  rate  at  which  product  sales  of  innovative  products  are  being  affected  by  biosimilar 
competition is increasing.

In the United States, the BPCIA authorizes the FDA to approve biosimilars via a separate, abbreviated pathway. See Item 
1.  Business—Government  Regulation—Regulation  in  the  United  States—Approval  of  Biosimilars.  In  the  United  States,  the 
FDA has approved numerous biosimilars, including biosimilar versions of Neulasta, EPOGEN and ENBREL, and a growing 
number  of  companies  have  announced  that  they  are  also  developing  biosimilar  versions  of  our  products.  For  example,  six 
biosimilar versions of Neulasta are now approved in the United States, and we expect that other biosimilar versions of Neulasta 
may be marketed or receive approval in the future. Impact to our Neulasta sales has accelerated as additional competitors have 
launched.  See  Item  1.  Business—Marketing,  Distribution  and  Selected  Marketed  Products—Competition.  Manufacturers  of 
biosimilars have attempted, and may in the future attempt, to compete with our products by offering lower list prices, greater 
discounts or rebates, or contracts that offer longer-term pricing or a broader portfolio of other products. Companies pursuing 
development of biosimilar versions of our products have challenged and may continue to challenge our patents well in advance 
of  the  expiration  of  our  material  patents.  For  examples  of  and  information  related  to  our  biosimilars  and  generics  patent 
litigation,  see  Part  IV—Note  19,  Contingencies  and  commitments,  to  the  Consolidated  Financial  Statements.  See  Our 
intellectual property positions may be challenged, invalidated or circumvented, or we may fail to prevail in current and future 
intellectual property litigation.

The  U.S.  biosimilar  pathway  includes  the  option  for  biosimilar  products  that  meet  certain  criteria  to  be  approved  as 
interchangeable with their reference products. Some companies currently developing or already marketing biosimilars may seek 
to obtain interchangeable status from the FDA, which could potentially allow pharmacists to substitute those biosimilars for our 
reference  products  without  prior  approval  from  the  prescriber  in  most  states  under  state  law.  The  FDA  approved  the  first 
interchangeable biosimilar in 2021 and has subsequently granted interchangeability designations to three additional biosimilars. 
In 2019, the FDA issued draft guidance that provides that comparative immunogenicity studies will not generally be expected 
for biosimilar and interchangeable insulin products. This has opened the door for other product-specific guidance development 
and  the  removal  of  the  expectation  for  certain  studies,  which  may  contribute  to  increased  biosimilar  competition  for  our 
innovative products. For example, in August 2022, the FDA designated a monoclonal antibody biosimilar as interchangeable 
without  requiring  a  switching  study  to  support  the  interchangeability  determination.  Further,  in  September  2022,  the  FDA 
indicated that while comparative clinical trials will continue to be a requirement for many biosimilar development programs, 
the agency is focused on reducing the need for them in the future through a range of statistical, analytical and pharmacologic 
approaches.

In addition, critics of the 12-year exclusivity period in the biosimilar pathway law will likely continue to seek to shorten 
the  data  exclusivity  period  and/or  to  encourage  the  FDA  to  interpret  narrowly  the  law’s  provisions  regarding  which  new 
products  receive  data  exclusivity.  In  2019,  the  Administration  agreed  to  remove  from  the  United  States-Mexico-Canada 
Agreement a requirement for at least 10 years of data exclusivity for biologic products. Also, the FDA is considering whether 
subsequent  changes  to  a  licensed  biologic  would  be  protected  by  the  remainder  of  the  reference  product’s  original  12-year 
exclusivity  period  (a  concept  known  in  the  generic  drug  context  as  “umbrella  exclusivity”).  If  the  FDA  were  to  decide  that 
umbrella exclusivity does not apply to biological reference products or were to make other changes to the exclusivity period, 

39

this could expose us to biosimilar competition at an earlier time. There also have been, and may continue to be, legislative and 
regulatory  efforts  to  promote  competition  through  policies  enabling  easier  generic  and  biosimilar  approval  and 
commercialization, including efforts to lower standards for demonstrating biosimilarity or interchangeability, limit patents that 
may  be  litigated  and/or  patent  settlements,  implement  preferential  reimbursement  policies  for  biosimilars  and  pass  new  laws 
requiring more disclosure in the FDA’s Orange and Purple Books. For example, in 2021 the FDA sent a letter to the USPTO 
describing  ways  to  strengthen  coordination  between  the  two  agencies,  offered  training  to  help  identify  prior  art,  and  seeking 
USPTO’s  views  on  practices  that  extend  market  exclusivities,  whether  pharmaceutical  patent  examiners  need  additional 
resources, and the effect of post-grant challenges at the Patent Trial and Appeal Board on drug patents. The USPTO responded 
in July 2022 with a letter to the FDA stating that it is prepared to create formal mechanisms to collaborate with the FDA on 
patent  issues  that  may  affect  the  timing  of  generic  and  biosimilar  entry.  In  January  2023,  the  USPTO  held  a  joint  listening 
session with the FDA on USPTO-FDA collaboration efforts.

Upon  the  expiration  or  loss  of  patent  protection  and/or  applicable  exclusivity  for  one  of  our  products,  we  can  lose  the 
majority of revenues for that product in a very short period of time. See Item 1. Business—Marketing, Distribution and Selected 
Marketed Products—Competition. Additionally, if one of our products is the subject of an FDA Written Request for pediatric 
studies and we are unable to adequately complete these studies, we may not obtain the pediatric exclusivity award that extends 
unexpired  regulatory  exclusivity  for  the  product  (and  existing  patents  for  a  small  molecule  product)  by  an  additional  six 
months. 

While we are unable to predict the precise effects of biosimilars and generics on our products, we are currently facing and 
expect to face greater competition in the United States, Europe and elsewhere as a result of biosimilar and generic competition 
and,  in  turn,  downward  pressure  on  our  product  prices  and  sales.  This  competition  has  had,  and  could  increasingly  have,  a 
material  adverse  effect  on  our  product  sales,  business  and  results  of  operations.  State  laws  may  also  have  an  impact  on  our 
business.  For  example,  California  is  the  first  state  to  have  passed  legislation,  effective  on  January  1,  2020,  against  “pay  for 
delay” settlements of patent infringement claims filed by manufacturers of generics or biosimilars where anything of value is 
given in exchange for settlement. Under this law, such settlement agreements are presumptively anticompetitive. The law may 
result  in  prolonged  litigation  and  fewer  settlements.  Other  states,  including  Connecticut,  New  York,  Illinois  and  Minnesota, 
may adopt similar laws or a similar law could be adopted at the federal level.

Concentration of sales at certain of our wholesaler distributors and consolidation of private payers may negatively affect 

our business.

Certain of our distributors, customers and payers have substantial purchasing leverage, due to the volume of our products 
they purchase or the number of patient lives for which they provide coverage. The substantial majority of our U.S. product sales 
is made to three pharmaceutical product wholesaler distributors: McKesson Corporation, AmerisourceBergen Corporation and 
Cardinal Health, Inc. These distributors, in turn, sell our products to their customers, which include physicians or their clinics, 
dialysis centers, hospitals and pharmacies. Similarly, as discussed above, there has been significant consolidation in the health 
insurance industry, including that a small number of PBMs now oversee a substantial percentage of total covered lives in the 
United States. See Our sales depend on coverage and reimbursement from government and commercial third-party payers, and 
pricing  and  reimbursement  pressures  have  affected,  and  are  likely  to  continue  to  affect,  our  profitability.  The  three  largest 
PBMs  in  the  United  States  are  now  part  of  major  health  insurance  providers.  The  growing  concentration  of  purchasing  and 
negotiating power by these entities has, and may continue to, put pressure on our pricing due to their ability to extract price 
discounts  on  our  products,  fees  for  other  services  or  rebates,  negatively  affecting  our  bargaining  position,  sales  and/or  profit 
margins.  In  addition,  decisions  by  these  entities  to  purchase  or  cover  less  or  none  of  our  products  in  favor  of  competing 
products could have a material adverse effect on our product sales, business and results of operations due to their purchasing 
volume. Further, if one of our significant wholesale distributors encounters financial or other difficulties and becomes unable or 
unwilling to pay us all amounts that such distributor owes us on a timely basis, or at all, it could negatively affect our business 
and results of operations. In addition, if one of our significant wholesale distributors becomes insolvent or otherwise unable to 
continue its commercial relationship with us in its present form, it could significantly disrupt our business and adversely affect 
our product sales, our business and results of operations unless suitable alternatives are timely found or lost sales are absorbed 
by another distributor.

RISKS RELATED TO RESEARCH AND DEVELOPMENT

We may not be able to develop commercial products despite significant investments in R&D.

Amgen invests heavily in R&D. Successful product development in the biotechnology industry is highly uncertain, and 
very  few  R&D  projects  yield  approved  and  commercially  viable  products.  Product  candidates,  including  biosimilar  product 
candidates, or new indications for existing products (collectively, product candidates) that appear promising in the early phases 
of development have failed to reach the market for a number of reasons, such as:

•

•

•

•

•

•

•

•

the product candidate did not demonstrate acceptable clinical trial results even though it achieved its primary endpoints 
and/or  demonstrated  positive  preclinical  or  early  clinical  trial  results,  for  reasons  that  could  include  changes  in  the 
standard of care of medicine or expectations of health authorities;

the product candidate was not effective or not more effective than currently available or potentially competitive therapies 
in treating a specified condition or illness;

the product candidate was not cost effective in light of existing or potentially competitive therapeutics;

the product candidate had harmful side effects in animals or humans;

the necessary regulatory bodies, such as the FDA or EMA, did not approve the product candidate for an intended use;

reimbursement for the product candidate is limited despite regulatory approval;

the product candidate was not economical for us to manufacture and commercialize;

other parties had or may have had proprietary rights relating to our product candidate, such as patent rights, and did not let 
us sell it on reasonable terms, or at all;

• we  and  certain  of  our  licensees,  partners,  contracted  organizations  or  independent  investigators  failed  to  effectively 

conduct clinical development or clinical manufacturing activities; 

•

•

•

the pathway to regulatory approval or reimbursement for product candidates was uncertain or not well-defined;

the biosimilar product candidate failed to demonstrate the requisite biosimilarity to the applicable reference product, or 
was otherwise determined by a regulatory authority to not meet applicable standards for approval; and

a  companion  diagnostic  device  that  is  required  with  the  use  of  a  product  candidate  is  not  approved  by  the  necessary 
regulatory authority.

We have spent considerable time, energy and resources developing our expertise in human genetics and acquiring access 
to libraries of genetic information with the belief that genetics could meaningfully aid our search for new medicines and help 
guide our R&D decisions and investments. We have focused our R&D strategy on drug targets validated by genetic or other 
compelling  human  evidence.  However,  product  candidates  based  on  genetically  validated  targets  remain  subject  to  the 
uncertainties  of  the  drug  development  process  and  may  not  reach  the  market  for  a  number  of  reasons,  including  the  factors 
listed above.

We  must  conduct  clinical  trials  in  humans  before  we  commercialize  and  sell  any  of  our  product  candidates  or  existing 

products for new indications.

Before  a  product  may  be  sold,  we  must  conduct  clinical  trials  to  demonstrate  that  our  product  candidates  are  safe  and 
effective  for  use  in  humans.  The  results  of  those  clinical  trials  are  used  as  the  basis  to  obtain  approval  from  regulatory 
authorities  such  as  the  FDA  and  EMA.  See  Our  current  products  and  products  in  development  cannot  be  sold  without 
regulatory approval. We are required to conduct clinical trials using an appropriate number of trial sites and patients to support 
the  product  label  claims.  The  length  of  time,  number  of  trial  sites  and  number  of  patients  required  for  clinical  trials  vary 
substantially, and we may spend several years and incur substantial expense in completing certain clinical trials. In addition, we 
may  have  difficulty  finding  a  sufficient  number  of  clinical  trial  sites  and/or  patients  to  participate  in  our  clinical  trials, 
particularly if competitors are conducting clinical trials in similar patient populations. See The COVID-19 pandemic, and the 
public and governmental effort to mitigate against the spread of the disease, have had, and are expected to continue to have, an 
adverse effect, and may have a material adverse effect, on our clinical trials, operations, supply chains, distribution systems, 
product development, product sales, business and results of operations. Patients may withdraw from clinical trials at any time, 
and privacy laws and/or other restrictions in certain countries may restrict the ability of clinical trial investigators to conduct 
further follow-up on such patients, which may adversely affect the interpretation of study results. Delays and complications in 

41

planned  clinical  trials  can  result  in  increased  development  costs,  associated  delays  in  regulatory  approvals  and  in  product 
candidates reaching the market and revisions to existing product labels.

Further,  to  increase  the  number  of  patients  available  for  enrollment  in  our  clinical  trials,  we  have  opened,  and  will 
continue to open, clinical sites and enroll patients in a number of locations where our experience conducting clinical trials is 
more limited, including India, China, South Korea, the Philippines, Singapore and some Central and South American countries, 
either through utilization of third-party contract clinical trial providers entirely or in combination with local staff. Conducting 
clinical trials in locations where we have limited experience requires substantial time and resources to understand the unique 
regulatory environments of individual countries. For other examples of the risks of conducting clinical trials in China, see also 
Our sales and operations are subject to the risks of doing business internationally, including in emerging markets. Further, we 
must ensure the timely production, distribution and delivery of the clinical supply of our product candidates to numerous and 
varied  clinical  trial  sites.  Additionally,  regional  disruptions,  including  natural  and  man-made  disasters,  health  emergencies 
(such as novel viruses or pandemics such as the one we are currently experiencing with COVID-19), or geopolitical conflicts 
(such as the ongoing armed conflict in Ukraine) have significantly disrupted the timing of clinical trials, and in the future could 
disrupt the timing, execution and outcome of clinical trials. If we fail to adequately manage the design, execution and diverse 
regulatory  aspects  of  our  clinical  trials  or  to  manage  the  production  or  distribution  of  our  clinical  supply,  or  such  sites 
experience  disruptions  as  a  result  of  a  natural/man-made  disaster,  health  emergency  or  geopolitical  conflict,  corresponding 
regulatory  approvals  may  be  delayed  or  we  may  fail  to  gain  approval  for  our  product  candidates  or  could  lose  our  ability  to 
market existing products in certain therapeutic areas or altogether. For example, our clinical trials have been adversely affected 
by  the  COVID-19  pandemic.  See  The  COVID-19  pandemic,  and  the  public  and  governmental  effort  to  mitigate  against  the 
spread  of  the  disease,  have  had,  and  are  expected  to  continue  to  have,  an  adverse  effect,  and  may  have  a  material  adverse 
effect, on our clinical trials, operations, supply chains, distribution systems, product development, product sales, business and 
results  of  operations.  If  we  are  unable  to  market  and  sell  our  products  or  product  candidates  or  to  obtain  approvals  in  the 
timeframe needed to execute our product strategies, our business and results of operations could be materially and adversely 
affected.

We  rely  on  independent  third-party  clinical  investigators  to  recruit  patients  and  conduct  clinical  trials  on  our  behalf  in 
accordance  with  applicable  study  protocols,  laws  and  regulations.  Further,  we  rely  on  unaffiliated  third-party  vendors  to 
perform certain aspects of our clinical trial operations. In some circumstances, we enter into co-development arrangements with 
other pharmaceutical and medical devices companies that provide for the other company to conduct certain clinical trials for the 
product we are co-developing or to develop a diagnostic test used in screening or monitoring patients in our clinical trials. See 
Some of our pharmaceutical pipeline and our commercial product sales rely on collaborations with third parties, which may 
adversely affect the development and sales of our products. We also may acquire companies that have past or ongoing clinical 
trials or rights to products or product candidates for which clinical trials have been or are being conducted. These trials may not 
have been conducted to the same standards as ours; however, once an acquisition has been completed we assume responsibility 
for the conduct of these trials, including any potential risks and liabilities associated with the past and prospective conduct of 
those  trials.  If  regulatory  authorities  determine  that  we  or  others,  including  our  licensees  or  co-development  partners,  or  the 
independent investigators or vendors selected by us, our co-development partners or by a company we have acquired or from 
which we have acquired rights to a product or product candidate, have not complied with regulations applicable to the clinical 
trials,  those  authorities  may  refuse  or  reject  some  or  all  of  the  clinical  trial  data  or  take  other  actions  that  could  delay  or 
otherwise negatively affect our ability to obtain or maintain marketing approval of the product or indication. In addition, delays 
or failures to develop diagnostic tests for our clinical trials can affect the timely enrollment of such trials and lead to delays or 
inability to obtain marketing approval. If we were unable to market and sell our products or product candidates, our business 
and results of operations could be materially and adversely affected.

In addition, some of our clinical trials utilize drugs manufactured and marketed by other pharmaceutical companies. These 
drugs may be administered in clinical trials in combination with one of our products or product candidates or in a head-to-head 
study  comparing  the  products’  or  product  candidates’  relative  efficacy  and  safety.  In  the  event  that  any  of  these  vendors  or 
pharmaceutical companies have unforeseen issues that negatively affect the quality of their work product or create a shortage of 
supply, or if we are otherwise unable to obtain an adequate supply of these other drugs, our ability to complete our applicable 
clinical trials and/or evaluate clinical results may also be negatively affected. As a result, such quality or supply problems could 
adversely affect our ability to timely file for, gain or maintain regulatory approvals worldwide.

Clinical  trials  must  generally  be  designed  based  on  the  current  standard  of  medical  care.  However,  in  certain  diseases, 
such as cancer, the standard of care is evolving rapidly. In some cases, we may design a clinical trial based on the standard of 
care we anticipate will exist at the time our study is completed. The duration of time needed to complete certain clinical trials 
may  result  in  the  design  of  such  clinical  trials  being  based  on  standards  of  medical  care  that  are  no  longer  or  that  have  not 
become  the  current  standards  by  the  time  such  trials  are  completed,  limiting  the  utility  and  application  of  such  trials. 
Additionally, the views of regulatory agencies relating to the requirements for accelerated approval may change over time, and 
trial designs that were sufficient to support accelerated approvals for some oncology products may not be considered sufficient 

42

for  later  candidates.  We  may  not  obtain  favorable  clinical  trial  results  and  therefore  may  not  be  able  to  obtain  regulatory 
approval  for  new  product  candidates  or  new  indications  for  existing  products  and/or  maintain  our  current  product  labels. 
Participants in clinical trials of our products and product candidates may also suffer adverse medical events or side effects that 
could, among other factors, delay or terminate clinical trial programs and/or require additional or longer trials to gain approval.

Even after a product is on the market, safety concerns may require additional or more extensive clinical trials as part of a 
risk management plan for our product or for approval of a new indication. Additional clinical trials we initiate, including those 
required by the FDA, could result in substantial additional expense, and the outcomes could result in further label restrictions or 
the loss of regulatory approval for an approved indication, each of which could have a material adverse effect on our product 
sales, business and results of operations. Additionally, any negative results from such trials could materially affect the extent of 
approvals, the use, reimbursement and sales of our products, our business and results of operations. 

Our current products and products in development cannot be sold without regulatory approval.

Our business is subject to extensive regulation by numerous state and federal government authorities in the United States, 
including the FDA, and by foreign regulatory authorities, including the EMA. We are required in the United States and in the 
other regions and countries in which we, or our partners and affiliates, sell to obtain approval from regulatory authorities before 
we manufacture, market and sell our products. Once our products are approved, the FDA and other U.S. and ex-U.S. regulatory 
agencies have substantial authority to require additional testing and reporting, perform inspections, change product labeling or 
mandate  withdrawals  of  our  products.  Failure  to  comply  with  applicable  regulatory  requirements  may  subject  us  to 
administrative and/or judicially imposed sanctions or monetary penalties as well as reputational and other harms. The sanctions 
could  include  the  FDA’s  or  ex-U.S.  regulatory  authorities’  refusals  to  approve  pending  applications,  delays  in  obtaining  or 
withdrawals  of  approvals,  delays  or  suspensions  of  clinical  trials,  warning  letters,  product  recalls  or  seizures,  total  or  partial 
suspensions of our operations, injunctions, fines, civil penalties and/or criminal prosecutions.

Obtaining and maintaining regulatory approvals have been, and will continue to be, increasingly difficult, time-consuming 
and costly. Legislative bodies or regulatory agencies could enact new laws or regulations, change existing laws or regulations or 
change their interpretations of laws or regulations at any time, which could affect our ability to obtain or maintain approval of 
our products or product candidates. The rate and degree of change in existing laws and regulations and regulatory expectations 
have accelerated in established markets, and regulatory expectations continue to evolve in emerging markets. We are unable to 
predict whether and when any further changes to laws or regulatory policies affecting our business could occur, such as changes 
to  laws  or  regulations  governing  manufacturer  communications  concerning  drug  products  and  drug  product  candidates  and 
whether such changes could have a material adverse effect on our product sales, business and results of operations. Further, we 
are  reliant  on  regulators  having  the  resources  necessary  to  evaluate  and  approve  our  products.  In  the  United  States,  a  partial 
federal government shutdown halted the work of many federal agencies and their employees from late December 2018 through 
late  January  2019.  A  subsequent  extended  shutdown  could  result  in  reductions  or  delays  of  FDA’s  activities,  including  with 
respect to our ongoing clinical programs, our manufacturing of our products and product candidates and our product approvals.

Regulatory authorities have questioned, and may in the future question, the sufficiency for approval of the endpoints we 
select  for  our  clinical  trials.  A  number  of  our  products  and  product  candidates  have  been  evaluated  in  clinical  trials  using 
surrogate  endpoints  that  measure  an  effect  that  is  known  to  correlate  with  an  ultimate  clinical  benefit.  For  example,  a 
therapeutic oncology product candidate may be evaluated for its ability to reduce or eliminate minimal residual disease (MRD), 
or to extend the length of time during and after the treatment that a patient lives without the disease worsening, measured by 
PFS.  Demonstrating  that  the  product  candidate  induces  MRD-negative  responses  or  produces  a  statistically  significant 
improvement in PFS does not necessarily mean that the product candidate will show a statistically significant improvement in 
overall  survival  or  the  time  that  the  patients  remain  alive.  In  the  CV  setting,  a  heart  disease  therapeutic  candidate  may  be 
evaluated for its ability to reduce LDL-C levels, as an elevated LDL-C level has been a surrogate endpoint for CV events such 
as  death,  heart  attack  and  stroke.  The  use  of  surrogate  endpoints  such  as  PFS  and  LDL-C  reduction,  in  the  absence  of  other 
measures  of  clinical  benefit,  may  not  be  sufficient  for  broad  usage  or  approval  even  when  such  results  are  statistically 
significant.  Regulatory  authorities  could  also  add  new  requirements,  such  as  the  completion  of  enrollment  in  a  confirmatory 
study  or  the  completion  of  an  outcomes  study  or  a  meaningful  portion  of  an  outcomes  study,  as  conditions  for  obtaining 
approval or obtaining an indication. For example, despite demonstrating that Repatha reduced LDL-C levels in a broad patient 
population, only after our large phase 3 outcomes study evaluating the ability of Repatha to prevent CV events met certain of its 
primary composite endpoint and key secondary composite endpoint did the FDA grant a broader approval of Repatha to reduce 
the  risk  of  certain  CV  events.  There  may  also  be  situations  in  which  demonstrating  the  efficacy  and  safety  of  a  product 
candidate may not be sufficient to gain regulatory approval unless superiority to other existing treatment options can be shown. 
The imposition of additional requirements or our inability to meet them in a timely fashion, or at all, has delayed, and may in 
the future delay, our clinical development and regulatory filing efforts, delay or prevent us from obtaining regulatory approval 
for new product candidates or new indications for existing products, or prevent us from maintaining our current product labels.

43

Some  of  our  products  have  been  approved  by  U.S.  and  ex-U.S.  regulatory  authorities  on  an  accelerated  or  conditional 
basis with full approval conditioned upon fulfilling the requirements of regulators. For example, in May 2021, we announced 
that the FDA approved LUMAKRAS under accelerated approval for the treatment of adult patients with KRAS G12C-mutated 
local advanced or metastatic NSCLC, as determined by an FDA-approved test, who have received at least one prior systemic 
therapy.  Continued  approval  for  this  indication  is  contingent  upon  verification  and  description  of  clinical  benefit  in 
confirmatory trials, including a requirement by the FDA that we complete a post-marketing trial to investigate whether a lower 
dose will have a similar clinical effect to the results demonstrated in our pre-marketing trial. We have since received the data 
from such post-marketing trial and intend to submit it to the FDA, as required. Regulatory authorities are placing greater focus 
on monitoring products originally approved on an accelerated or conditional basis and on whether the sponsors of such products 
have met the conditions of the accelerated or conditional approvals. If we are unable to fulfill the regulators’ requirements that 
were conditions of a product’s accelerated or conditional approval and/or if regulators reevaluate the data or risk-benefit profile 
of our product, the conditional approval may not result in full approval or may be revoked or not renewed. Alternatively, we 
may be required to change the product’s labeled indications or even withdraw the product from the market.

Regulatory authorities can also impose post-marketing pediatric study requirements. Failure to fulfill such requirements 
may  result  in  regulatory  or  enforcement  action,  including  financial  penalties  or  the  invalidation  of  a  product’s  marketing 
authorization.

Safety  problems  or  signals  can  arise  as  our  products  and  product  candidates  are  evaluated  in  clinical  trials,  including 
investigator sponsored studies, or as our marketed products are used in clinical practice. We are required continuously to collect 
and  assess  adverse  events  reported  to  us  and  to  communicate  to  regulatory  agencies  these  adverse  events  and  safety  signals 
regarding  our  products.  Regulatory  agencies  periodically  perform  inspections  of  our  pharmacovigilance  processes,  including 
our adverse event reporting. In the United States, for our products with approved REMS (see Item 1. Business—Government 
Regulation—Postapproval  Phase),  we  are  required  to  submit  periodic  assessment  reports  to  the  FDA  to  demonstrate  that  the 
goals  of  the  REMS  are  being  met.  REMS  and  other  risk  management  programs  are  designed  to  help  ensure  that  a  drug’s 
benefits outweigh the risks and vary in the elements they contain. If the FDA is not satisfied with the results of the periodic 
assessment reports we submit for any of our REMS, the FDA may also modify our REMS or take other regulatory actions, such 
as implementing revised or restrictive labeling. The drug delivery devices approved for use in combination with our products 
are also subject to regulatory oversight and review for safety and malfunctions. See Some of our products are used with drug 
delivery or companion diagnostic devices that have their own regulatory, manufacturing and other risks. If regulatory agencies 
determine  that  we  or  other  parties  (including  our  clinical  trial  investigators,  those  operating  our  patient  support  programs  or 
licensees of our products) have not complied with the applicable reporting, other pharmacovigilance or other safety or quality 
assessment  requirements,  we  may  become  subject  to  additional  inspections,  warning  letters  or  other  enforcement  actions, 
including fines, marketing authorization withdrawal and other penalties. Our product candidates and marketed products can also 
be affected by safety problems or signals occurring with respect to products that are similar to ours or that implicate an entire 
class of products. Further, as a result of clinical trials, including sub-analyses or meta-analyses of earlier clinical trials (a meta-
analysis involves the use of various statistical methods to combine results from previous separate but related studies) performed 
by  us  or  others,  concerns  may  arise  about  the  sufficiency  of  the  data  or  studies  underlying  a  product’s  approved  label.  Such 
actual or perceived safety problems or concerns can lead to:

•

•

•

•

•

•

•

•

revised or restrictive labeling for our products, or the potential for restrictive labeling that has resulted, and may in the 
future result, in our decision not to commercialize a product candidate;

requirement of risk management or minimization activities or other regulatory agency compliance actions related to the 
promotion and sale of our products;

post-marketing  commitments,  mandated  post-marketing  requirements  or  pharmacovigilance  programs  for  our  approved 
products;

product recalls of our approved products;

required changes to the processes used in the manufacture of our products, which could increase our manufacturing costs 
and affect the availability of contract manufacturers we may utilize to assist in such manufacturing;

revocation of approval for our products from the market completely, or within particular therapeutic areas or patient types;

increased timelines or delays in being approved by the FDA or other regulatory bodies; and/or

treatments or product candidates not being approved by regulatory bodies.

For example, after an imbalance in positively adjudicated CV serious adverse events was observed in one of the phase 3 
clinical  trials  for  EVENITY  but  not  in  another,  larger  phase  3  study,  in  April  2019  the  FDA  approved  EVENITY  for  the 

44

treatment  of  osteoporosis  in  postmenopausal  women  at  high  risk  for  fracture,  along  with  a  post-marketing  requirement.  The 
requirement includes a five-year observational feasibility study that could be followed by a comparative safety study or trial.

In addition to our innovative products, we are working to develop and commercialize biosimilar versions of a number of 
products  currently  manufactured,  marketed  and  sold  by  other  pharmaceutical  companies.  In  some  markets,  there  is  not  yet  a 
legislative or regulatory pathway for the approval of biosimilars. In the United States, the BPCIA provided for such a pathway. 
Discussions within the FDA and other regulatory authorities, and between regulatory authorities and sponsors, continue as to 
the evidence needed to demonstrate biosimilarity or interchangeability for specific products. See We currently face competition 
from biosimilars and generics and expect to face increasing competition from biosimilars and generics in the future. Delays or 
uncertainties  in  the  development  or  implementation  of  such  pathways,  or  changes  in  existing  regulatory  pathways,  including 
degradation  of  regulatory  standards,  could  result  in  delays  or  difficulties  in  getting  our  biosimilar  products  approved  by 
regulatory authorities, subject us to unanticipated development costs or otherwise reduce the value of the investments we have 
made in the biosimilars area. Further, we cannot predict the extent to which any potential legislative or policy initiatives would 
affect  the  biosimilar  pathway  or  have  a  material  adverse  effect  on  our  development  of  biosimilars  or  on  our  marketed 
biosimilars.  In  addition,  if  we  are  unable  to  bring  our  biosimilar  products  to  market  on  a  timely  basis  and  secure  “first-to-
market” or other advantageous positions, our future biosimilar sales, business and results of operations could be materially and 
adversely affected.

Some  of  our  products  are  used  with  drug  delivery  or  companion  diagnostic  devices  that  have  their  own  regulatory, 

manufacturing and other risks.

Many of our products and product candidates may be used in combination with a drug delivery device, such as an injector 
or  other  delivery  system.  For  example,  Neulasta  is  available  as  part  of  the  Neulasta  Onpro  kit,  and  our  AutoTouch  reusable 
autoinjector  is  used  with  ENBREL  Mini  single-dose  prefilled  cartridges.  In  addition,  some  of  our  products  or  product 
candidates,  including  many  of  our  oncology  product  candidates  and  products,  including  LUMAKRAS/LUMYKRAS  and 
bemarituzumab, may also require the use of a companion or other diagnostic device such as a device that determines whether 
the patient is eligible to use our drug or that helps ensure its safe and effective use. In some regions, including the United States, 
regulatory authorities may require contemporaneous approval of the companion diagnostic device and the therapeutic product; 
in others the regulatory authorities may require a separate study of the companion diagnostic device. Our product candidates or 
expanded indications of our products used with such devices may not be approved or may be substantially delayed in receiving 
regulatory approval if development or approval of such devices is delayed, such devices do not also gain or maintain regulatory 
approval or clearance, or if such devices do not remain commercially available. When approval of the product and device is 
sought  under  a  single  marketing  drug  application,  the  increased  complexity  of  the  review  process  may  delay  receipt  of 
regulatory approval. In addition, some of these devices may be provided by single-source unaffiliated third-party companies. 
We are dependent on the sustained cooperation and effort of those third-party companies to supply and/or market the devices 
and, in some cases, to conduct the studies required for approval or clearance by the applicable regulatory agencies. We are also 
dependent  on  those  third-party  companies  continuing  to  meet  applicable  regulatory  or  other  requirements.  Failure  to 
successfully develop, modify, or supply the devices, delays in or failures of the Amgen or third-party studies, or failure of us or 
the  third-party  companies  to  obtain  or  maintain  regulatory  approval  or  clearance  of  the  devices  could  result  in  increased 
development  costs;  delays  in,  or  failure  to  obtain  or  maintain,  regulatory  approval;  and/or  associated  delays  in  a  product 
candidate reaching the market or in the addition of new indications for existing products. We are also required to collect and 
assess  user  complaints,  adverse  events  and  malfunctions  regarding  our  devices,  and  actual  or  perceived  safety  problems  or 
concerns  with  a  device  used  with  our  product  can  lead  to  regulatory  actions  and  adverse  effects  on  our  products.  See  Our 
current products and products in development cannot be sold without regulatory approval. Additionally, regulatory agencies 
conduct routine monitoring and inspections to identify and evaluate potential issues with our devices. For example, in 2017, the 
FDA  reported  on  its  adverse  event  reporting  system  that  it  was  evaluating  our  Neulasta  Onpro  kit.  Subsequently,  we 
implemented  device  and  labeling  enhancements  to  address  product  complaints  received  on  this  device.  We  continuously 
monitor  complaints  and  adverse  events  and  implement  additional  enhancements  as  needed.  Loss  of  regulatory  approval  or 
clearance  of  a  device  that  is  used  with  our  product  may  also  result  in  the  removal  of  our  product  from  the  market.  Further, 
failure to successfully develop, supply, or gain or maintain approval for these devices could adversely affect sales of the related 
approved products.

Some of our pharmaceutical pipeline and our commercial product sales rely on collaborations with third parties, which 

may adversely affect the development and sales of our products.

We  depend  on  alliances  with  other  companies,  including  pharmaceutical  and  biotechnology  companies,  vendors  and 
service providers, for the development of a portion of the products in our pharmaceutical pipeline and for the commercialization 
and sales of certain of our commercial products. For example, we have collaborations with third parties under which we share 
development  rights,  obligations  and  costs  and/or  commercial  rights  and  obligations.  See  Item  1.  Business—Business 
Relationships.

45

Failures  by  these  parties  to  meet  their  contractual,  regulatory,  or  other  obligations  to  us  or  any  disruption  in  the 
relationships  between  us  and  these  third  parties,  could  have  a  material  adverse  effect  on  our  pharmaceutical  pipeline  and 
business. In addition, our collaborative relationships for R&D and/or commercialization and sales often extend for many years 
and have given, and may in the future give, rise to disputes regarding the relative rights, obligations and revenues of us and our 
collaboration  partners,  including  the  ownership  or  prosecution  of  intellectual  property  and  associated  rights  and  obligations. 
This  could  result  in  the  loss  of  intellectual  property  rights  or  protection,  delay  the  development  and  sale  of  potential 
pharmaceutical  products,  affect  the  sale  and  delivery  of  our  commercialized  products  and  lead  to  lengthy  and  expensive 
litigation, administrative proceedings or arbitration. 

Our efforts to collaborate with or acquire other companies, products, or technology, and to integrate the operations of 
companies or to support the products or technology we have acquired, may not be successful, and may result in unanticipated 
costs, delays or failures to realize the benefits of the transactions.

We  seek  innovation  through  significant  investment  in  both  internal  R&D  and  external  transactions,  including 
collaborations,  partnerships,  alliances,  licenses,  joint  ventures,  mergers  and  acquisitions  (collectively,  acquisition  activity). 
Acquisition activities may be subject to regulatory approvals or other requirements that are not within our control. There can be 
no assurance that such regulatory or other approvals will be obtained or that all closing conditions required in connection with 
our acquisition activities will be satisfied or waived, which could result in us being unable to complete the planned acquisition 
activities.  In  addition,  antitrust  scrutiny  by  regulatory  agencies  and  changes  to  regulatory  approval  process  in  the  U.S.  and 
foreign  jurisdictions  may  cause  approvals  to  take  longer  than  anticipated  to  obtain,  not  be  obtained  at  all,  or  contain 
burdensome conditions, which may jeopardize, delay or reduce the anticipated benefits of acquisitions to us and could impede 
the execution of our business strategy.

Acquisition activities are complex, time consuming and expensive and may result in unanticipated costs, delays or other 
operational or financial problems related to integrating the acquired company and business with our company, which may divert 
our  management’s  attention  from  other  business  issues  and  opportunities  and  restrict  the  full  realization  of  the  anticipated 
benefits of such transactions within the expected timeframe or at all. We may pay substantial amounts of cash, incur debt or 
issue  equity  securities  to  pay  for  acquisition  activities,  which  could  adversely  affect  our  liquidity  or  result  in  dilution  to  our 
stockholders,  respectively.  Further,  failures  or  difficulties  in  integrating  or  retaining  new  personnel  or  in  integrating  the 
operations of the businesses, products or assets we acquire (including related technology, commercial operations, compliance 
programs,  manufacturing,  distribution  and  general  business  operations  and  procedures  and  ESG  activities)  may  affect  our 
ability  to  realize  the  benefits  of  the  transaction  and  grow  our  business  and  may  result  in  us  incurring  asset  impairment  or 
restructuring  charges.  These  and  other  challenges  may  arise  in  connection  with  our  acquisitions  of  Otezla,  Five  Prime, 
Teneobio,  ChemoCentryx,  Horizon  and/or  our  collaborations  with  BeiGene  and  KKC,  or  with  other  acquisition  activities, 
which could have a material adverse effect on our business, results of operations and stock price.

RISKS RELATED TO OPERATIONS

We  perform  a  substantial  majority  of  our  commercial  manufacturing  activities  at  our  facility  in  the  U.S.  territory  of 
Puerto Rico and a substantial majority of our clinical manufacturing activities at our facility in Thousand Oaks, California; 
significant disruptions or production failures at these facilities could significantly impair our ability to supply our products or 
continue our clinical trials.

The  global  supply  of  our  products  and  product  candidates  for  commercial  sales  and  for  use  in  our  clinical  trials  is 
significantly  dependent  on  the  uninterrupted  and  efficient  operation  of  our  manufacturing  facilities,  in  particular  those  in  the 
U.S. territory of Puerto Rico and Thousand Oaks, California. See Manufacturing difficulties, disruptions or delays could limit 
supply of our products and limit our product sales.

We  currently  perform  a  substantial  majority  of  our  clinical  manufacturing  that  supports  our  product  candidates  at  our 
facility  in  Thousand  Oaks,  California.  A  substantial  disruption  in  our  ability  to  operate  our  Thousand  Oaks  manufacturing 
facility could materially and adversely affect our ability to supply our product candidates for use in our clinical trials, leading to 
delays in development of our product candidates.

In addition, we currently perform a substantial majority of our commercial manufacturing activities at our facility in the 
U.S.  territory  of  Puerto  Rico.  In  recent  years,  Puerto  Rico  has  been  affected  by  a  number  of  natural  disasters,  including 
Hurricane  Maria  (2017),  earthquakes  (2020)  and  Hurricane  Fiona  (2022).  These  natural  disasters  have  affected,  and  may 
continue to affect, public and private properties and Puerto Rico’s electric grid and communications networks. While the critical 
manufacturing  areas  of  our  commercial  manufacturing  facility  were  not  significantly  affected  by  these  natural  disasters,  the 
restoration of electrical service on the island after Hurricane Maria was a slow process, and our facility relied on backup diesel 
powered generators for some time. We also operated on backup generators for a few weeks after the early 2020 earthquakes in 
Puerto Rico. In 2021, the baseload power generation units of the Puerto Rico Electric Power Authority malfunctioned due to the 

46

lack of adequate maintenance for over a decade, leading to selective outages across the island. In September 2022, Hurricane 
Fiona caused further damage to the island’s utility infrastructure which again resulted in widespread power outages and water 
supply issues. Although these events did not directly have a material effect on our business, they have resulted in disruptions to 
our  third-party  suppliers  on  the  island.  Further  instability  of  the  electric  grid  could  require  us  to  increase  our  use  of  our 
generators or to use them exclusively. In addition, future storms, earthquakes or other natural or man-made disasters or events 
(including  political  unrest  or  labor  shortages)  could  have  a  more  significant  effect  on  our  manufacturing  operations.  The 
COVID-19 pandemic has also resulted in disruptions to activities on the island. In March 2020, the Governor of Puerto Rico 
issued  Executive  Orders  requiring  the  lockdown  of  businesses  and  government  facilities,  imposing  restrictions  on  business 
operations and a curfew on residents in response to COVID-19. Additionally, during the summer of 2021, a labor dispute arose 
between  the  maritime  terminal  operation  company  and  its  employees,  represented  by  the  International  Longshoremen’s 
Association  (ILA),  which  resulted  in  a  strike  that  delayed  cargo  movement  from  the  San  Juan  Port  Zone  for  several  days. 
Hurricanes Maria and Fiona, the 2020 earthquakes, the COVID-19 pandemic and the ILA strike have also placed greater stress 
on the island’s already challenged economy. Beginning in 2016, the government of Puerto Rico defaulted on its roughly $72 
billion  of  debt.  In  response,  the  U.S.  Congress  passed  the  Puerto  Rico  Oversight,  Management,  and  Economic  Stability  Act, 
which established a financial oversight board for Puerto Rico. After years of negotiations with bondholders and other creditors, 
this  financial  oversight  board  reached  an  agreement  with  the  same,  which  was  confirmed  by  the  U.S.  District  Court  for  the 
District  of  Puerto  Rico  effective  March  2022.  Although  our  ability  to  manufacture  and  supply  our  products  has  not,  to  date, 
been significantly affected by natural disasters, unreliable electric utility services, strikes, pandemic lockdowns or the island’s 
economic  challenges,  these,  or  a  combination  of  these  challenges,  or  other  issues  that  create  a  substantial  disruption  to  our 
ability to operate our Puerto Rico manufacturing facility or get supplies and manufactured products transported to and from that 
location, could make it more expensive or difficult for us to operate in Puerto Rico, and could materially and adversely affect 
our ability to supply our products and affect our product sales. See Manufacturing difficulties, disruptions or delays could limit 
supply of our products and limit our product sales.

We rely on third-party suppliers for certain of our raw materials, medical devices and components.

We rely on unaffiliated third-party suppliers for certain raw materials, medical devices and components necessary for the 
manufacturing of our commercial and clinical products. Certain of those raw materials, medical devices and components are 
proprietary products of those unaffiliated third-party suppliers and are specifically cited in our drug applications with regulatory 
agencies so that they must be obtained from that specific sole source or sources and could not be obtained from another supplier 
unless  and  until  the  regulatory  agency  approved  such  supplier.  For  example,  we  rely  on  a  single  source  for  the  SureClick 
autoinjectors  used  in  the  drug  delivery  of  Repatha,  ENBREL,  Aimovig,  AMGEVITA  and  Aranesp.  Also,  certain  of  the  raw 
materials required in the commercial and clinical manufacturing of our products are sourced from other countries and/or derived 
from biological sources, including mammalian tissues, bovine serum and human serum albumin.

Among the reasons we may be unable to obtain these raw materials, medical devices and components include:

•

•

•

•

•

•

•

•

•

•

regulatory requirements or action by regulatory agencies or others;

adverse financial or other strategic developments at or affecting the supplier, including bankruptcy;

unexpected demand for or shortage of raw materials, medical devices or components;

failure to comply with our quality standards which results in quality and product failures, product contamination and/or 
recall;

a material shortage, contamination, recall and/or restrictions on the use of certain biologically derived substances or other 
raw materials;

discovery of previously unknown or undetected imperfections in raw materials, medical devices or components;

cyberattacks on supplier systems; 

natural or other disasters, including hurricanes, earthquakes, volcanoes or fires; 

labor disputes or shortages, including from the effects of health emergencies (such as novel viruses or pandemics such as 
the one we are currently experiencing with COVID-19) or natural disasters; and

geopolitical conflicts.

For example, in prior years we have experienced shortages in certain components necessary for the formulation, fill and 
finish  of  certain  of  our  products  in  our  Puerto  Rico  facility,  and  we  have  also  experienced  shortages  related  to  single  use 
systems  and  packaging  which  has  caused  disruptions  to  our  manufacturing  plans.  Further  quality  issues  that  result  in 

47

unexpected  additional  demand  for  certain  components  have  resulted  in  shortages  and  in  the  future  may  lead  to  shortages  of 
required raw materials or components (such as we have experienced with EPOGEN glass vials). We may experience similar or 
other  shortages  in  the  future  resulting  in  delayed  shipments,  supply  constraints,  clinical  trial  delays,  contract  disputes  and/or 
stock-outs of our products. These or other similar events could negatively affect our ability to satisfy demand for our products 
or conduct clinical trials, which could have a material adverse effect on our product sales, business and results of operations.

Manufacturing difficulties, disruptions or delays could limit supply of our products and limit our product sales.

Manufacturing  biologic  and  small  molecule  human  therapeutic  products  is  difficult,  complex  and  highly  regulated.  We 
manufacture  many  of  our  commercial  products  and  product  candidates  internally.  In  addition,  we  currently  use  third-party 
contract  manufacturers  to  produce,  or  assist  in  the  production  of,  a  number  of  our  products,  and  we  currently  use  contract 
manufacturers  to  produce,  or  assist  in  the  production  of,  a  number  of  our  late-stage  product  candidates  and  drug  delivery 
devices. See Item 1. Business—Manufacturing, Distribution and Raw Materials—Manufacturing. Our ability to adequately and 
timely  manufacture  and  supply  our  products  (and  product  candidates  to  support  our  clinical  trials)  is  dependent  on  the 
uninterrupted and efficient operation of our facilities and those of our third-party contract manufacturers, which may be affected 
by:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

capacity of manufacturing facilities;

contamination by microorganisms or viruses, or foreign particles from the manufacturing process;

natural or other disasters, including hurricanes, earthquakes, volcanoes or fires;

labor disputes or shortages, including the effects of health emergencies (such as novel viruses or pandemics such as the 
one we are currently experiencing with COVID-19) or natural disasters;

compliance with regulatory requirements;

changes in forecasts of future demand;

timing and actual number of production runs and production success rates and yields;

updates of manufacturing specifications;

contractual disputes with our suppliers and contract manufacturers;

timing and outcome of product quality testing;

power failures and/or other utility failures;

cyberattacks on supplier systems;

breakdown,  failure,  substandard  performance  or  improper  installation  or  operation  of  equipment  (including  our 
information technology systems and network-connected control systems or those of our contract manufacturers or third-
party service providers); 

delays in the ability of the FDA or foreign regulatory agencies to provide us necessary reviews, inspections and approvals, 
including as a result of a subsequent extended U.S. federal or other government shutdowns; and/or

geopolitical conflicts. 

If  any  of  these  or  other  problems  affect  production  in  one  or  more  of  our  facilities  or  those  of  our  third-party  contract 
manufacturers, or if we do not accurately forecast demand for our products or the amount of our product candidates required in 
clinical  trials,  we  may  be  unable  to  start  or  increase  production  in  our  unaffected  facilities  to  meet  demand.  If  the  efficient 
manufacture and supply of our products or product candidates is interrupted, we may experience delayed shipments, delays in 
our clinical trials, supply constraints, stock-outs, adverse event trends, contract disputes and/or recalls of our products. From 
time to time, we have initiated recalls of certain lots of our products. For example, in July 2014 we initiated a voluntary recall 
of an Aranesp lot distributed in the EU after particles were detected in a quality control sample following distribution of that lot, 
and  in  April  2018  we  initiated  a  precautionary  recall  of  two  batches  of  Vectibix  distributed  in  Switzerland  after  potential 
crimping  defects  were  discovered  in  the  metal  seals  on  some  product  vials.  If  we  are  at  any  time  unable  to  provide  an 
uninterrupted  supply  of  our  products  to  patients,  we  may  lose  patients  and  physicians  may  elect  to  prescribe  competing 
therapeutics instead of our products, which could have a material adverse effect on our product sales, business and results of 
operations.

48

Our  manufacturing  processes,  those  of  our  third-party  contract  manufacturers  and  those  of  certain  of  our  third-party 
service  providers  must  undergo  regulatory  approval  processes  and  are  subject  to  continued  review  by  the  FDA  and  other 
regulatory authorities. It can take longer than five years to build, validate and license another manufacturing plant, and it can 
take longer than three years to qualify and license a new contract manufacturer or service provider. If we elect or are required to 
make  changes  to  our  manufacturing  processes  because  of  new  regulatory  requirements,  new  interpretations  of  existing 
requirements  or  other  reasons,  this  could  increase  our  manufacturing  costs  and  result  in  delayed  shipments,  delays  in  our 
clinical  trials,  supply  constraints,  stock-outs,  adverse  event  trends  or  contract  negotiations  or  disputes.  Such  manufacturing 
challenges may also occur if our existing contract manufacturers are unable or unwilling to timely implement such changes, or 
at all.

In addition, regulatory agencies conduct routine monitoring and inspections of our manufacturing facilities and processes 
as well as those of our third-party contract manufacturers and service providers. If regulatory authorities determine that we or 
our  third-party  contract  manufacturers  or  certain  of  our  third-party  service  providers  have  violated  regulations,  they  may 
mandate corrective actions and/or issue warning letters, or even restrict, suspend or revoke our prior approvals, prohibiting us 
from manufacturing our products or conducting clinical trials or selling our marketed products until we or the affected third-
party  contract  manufacturers  or  third-party  service  providers  comply,  or  indefinitely.  See  also  Our  current  products  and 
products  in  development  cannot  be  sold  without  regulatory  approval.  Such  issues  may  also  delay  the  approval  of  product 
candidates we have submitted for regulatory review, even if such product candidates are not directly related to the products, 
devices  or  processes  at  issue  with  regulators.  Because  our  third-party  contract  manufacturers  and  certain  of  our  third-party 
service  providers  are  subject  to  the  FDA  and  foreign  regulatory  authorities,  alternative  qualified  third-party  contract 
manufacturers  and  third-party  service  providers  may  not  be  available  on  a  timely  basis,  or  at  all.  If  we  or  our  third-party 
contract manufacturers or third-party service providers cease or interrupt production or if our third-party contract manufacturers 
and  third-party  service  providers  fail  to  supply  materials,  products  or  services  to  us,  we  may  experience  delayed  shipments, 
delays  in  our  clinical  trials,  supply  constraints,  contract  disputes,  stock-outs  and/or  recalls  of  our  products.  Additionally,  we 
distribute a substantial volume of our commercial products through our primary distribution centers in Louisville, Kentucky for 
the United States and in Breda, Netherlands for Europe and much of the rest of the world. We also conduct most of the labeling 
and packaging of our products distributed in Europe and much of the rest of the world in Breda. Our ability to timely supply 
products  is  dependent  on  the  uninterrupted  and  efficient  operations  of  our  distribution  and  logistics  centers,  our  third-party 
logistics providers and our labeling and packaging facility in Breda. Further, we rely on commercial transportation, including 
air  and  sea  freight,  for  the  distribution  of  our  products  to  our  customers,  which  has  been  negatively  affected  by  the  ongoing 
COVID-19 pandemic and may be negatively affected by natural disasters or geopolitical security threats.

There  have  also  been  legislative  and  administrative  proposals  seeking  to  incentivize  greater  drug  manufacturing  in  the 
United  States  with  the  stated  goal  of  improving  supply  reliability  in  the  United  States.  For  example,  on  August  6,  2020,  the 
previous  Administration  issued  an  Executive  Order  aimed  at  boosting  domestic  production  of  essential  medicines,  medical 
countermeasures, and critical inputs titled “Executive Order on Ensuring Essential Medicines, Medical Countermeasures, and 
Critical  Inputs  are  Made  in  the  United  States.”  Additionally,  one  legislative  proposal  would  have  prohibited  the  U.S. 
Department  of  Veterans  Affairs  from  purchasing  certain  drugs  that  have  active  pharmaceutical  ingredients  manufactured 
outside the United States. While we perform a substantial majority of our commercial manufacturing activities in the United 
States, including in the U.S. territory of Puerto Rico, and a substantial majority of our clinical manufacturing activities at our 
facility in Thousand Oaks, California, the passage of such legislation could result in foreign governments enacting retaliatory 
legislation or regulatory actions, which may have an adverse effect on our product sales, business and results of operations.

Our  business  and  operations  may  be  negatively  affected  by  the  failure,  or  perceived  failure,  of  achieving  our 

environmental, social and governance objectives.

We  continue  to  work  towards  operating  our  business  in  an  environmentally  responsible  and  socially  inclusive  manner. 
Stakeholders, including our investors and our employees, have increasingly focused on, and are expected to continue to focus 
on,  our  ESG  practices.  If  our  ESG  practices  fail  to  meet  these  stakeholders’  expectations  and  standards,  there  could  be  a 
material adverse effect on our reputation, business and, ultimately, our stock price.

Our ESG report is made available on our website and describes our ESG goals and the progress we have made on the ESG 
issues deemed most important to our external and internal stakeholders, based on surveys, interviews and certain frameworks 
for corporate responsibility. Achieving our ESG goals requires long-term investments and broad, coordinated activity, and we 
may be required to incur additional costs or allocate additional resources towards monitoring, reporting and implementing our 
ESG practices. Further, we may fail to accurately assess our stakeholders’ ESG priorities, as such priorities have evolved and 
will continue to evolve. While we have achieved most of our goals set in prior years, whether we can achieve our current and 
future ESG goals continues to be uncertain and remains subject to numerous risks, including evolving regulatory requirements 
and social expectations affecting ESG practices, our ability to recruit, develop and retain a diverse workforce, the availability of 
suppliers and collaboration partners that can meet our ESG goals, the effects of the organic growth of our business and potential 

49

acquisitions of other businesses on our ESG performance, and the availability and cost of technologies or resources, such as 
carbon credits, that support our goals. For example, impacts on the commodity market and supply chains caused by the armed 
conflict  in  Ukraine  could  limit  the  availability  of  electric  vehicle  components,  impairing  our  ability  to  meet  some  of  our 
environmental  sustainability  goals.  Any  failure  or  perceived  failure  to  meet  our  ESG  program  priorities  could  result  in  a 
material adverse effect on our reputation, business and stock price.

The effects of global climate change and related natural disasters could negatively affect our business and operations.

Many of our operations and facilities, including those essential to our manufacturing, R&D and distribution activities, are 
in locations that are subject to natural disasters, including droughts, fires, extreme temperatures, hurricanes, tropical storms and/
or floods. For example, in 2017 Hurricane Maria caused catastrophic damage, compounded in 2022 by Hurricane Fiona, to the 
U.S. territory of Puerto Rico, where we perform a substantial majority of our commercial manufacturing activities. Although 
our site was well-protected and suffered minimal damage, there can be no assurances that we would have similar results in the 
face  of  future  natural  disasters.  The  severity  and  frequency  of  weather-related  natural  disasters  has  been  amplified,  and  is 
expected to continue to be amplified by, global climate change. Such natural disasters have caused, and in the future may cause, 
damage to and/or disrupt our operations, which may result in a material adverse effect on our product sales, business and results 
of operations. Our suppliers, vendors and business partners also face similar risks, and any disruption to their operations could 
have  an  adverse  effect  on  our  supply  and  manufacturing  chain.  Further,  many  of  our  key  facilities  are  located  on  islands, 
including Puerto Rico, Singapore and Ireland, which rely on essential port facilities that may be vulnerable to climate change-
related or other natural disasters. Although we have detailed business continuity plans in place and periodic assessments of our 
natural  disaster  risk,  any  natural  disaster  may  also  result  in  prolonged  interruption  to  our  critical  operational  and  business 
activities,  and  we  may  be  required  to  incur  significant  costs  to  remedy  the  effects  of  such  natural  disasters  and  fully  resume 
operations,  which  may  result  in  a  material  adverse  effect  on  our  product  sales,  business  and  results  of  operations.  See  We 
perform a substantial majority of our commercial manufacturing activities at our facility in the U.S. territory of Puerto Rico 
and  a  substantial  majority  of  our  clinical  manufacturing  activities  at  our  facility  in  Thousand  Oaks,  California;  significant 
disruptions or production failures at these facilities could significantly impair our ability to supply our products or continue 
our clinical trials and Manufacturing difficulties, disruptions or delays could limit supply of our products and limit our product 
sales.

GENERAL RISK FACTORS

Global economic conditions may negatively affect us and may magnify certain risks that affect our business.

Our  operations  and  performance  have  been,  and  may  continue  to  be,  affected  by  global  economic  conditions.  The 
economic  downturn  resulting  from  the  COVID-19  pandemic  precipitated  a  global  recession,  and  together  with  high  rates  of 
inflation and energy supply issues experienced in certain regions, have led to regional and/or global macroeconomic challenges, 
the  effects  of  which  may  be  of  an  extended  duration.  In  particular,  acute  rising  energy  costs  may  further  adversely  affect 
productivity and economic conditions in Europe. Additionally, financial pressures may cause government or other third-party 
payers to more aggressively seek cost containment measures in healthcare and other settings. See Our sales depend on coverage 
and  reimbursement  from  government  and  commercial  third-party  payers,  and  pricing  and  reimbursement  pressures  have 
affected,  and  are  likely  to  continue  to  affect,  our  profitability.  As  a  result  of  global  economic  conditions,  some  third-party 
payers  may  delay  or  be  unable  to  satisfy  their  reimbursement  obligations.  Job  losses  or  other  economic  hardships  (including 
inflation) may also affect patients’ ability to afford healthcare as a result of increased co-pay or deductible obligations, greater 
cost sensitivity to existing co-pay or deductible obligations, lost healthcare insurance coverage or for other reasons. We believe 
such conditions have led and could continue to lead to reduced demand for our products, which could have a material adverse 
effect  on  our  product  sales,  business  and  results  of  operations.  The  current  inflationary  environment  related  to  increased 
aggregate  demand,  supply  chain  constraints  and  the  effects  from  the  armed  conflict  in  Ukraine  (including  the  effects  of  the 
sanctions  that  were  implemented  in  response  to  the  conflict  and  the  resulting  impacts  on  the  commodity  market  and  supply 
chains) have also increased our operating expenses and may continue to affect our operating expenses. Our operational costs, 
including the cost of energy, materials, labor, distribution and our other operational and facilities costs are subject to market 
conditions and are being adversely affected by inflationary pressures. Economic conditions may also adversely affect the ability 
of our distributors, customers and suppliers to obtain the liquidity required to buy inventory or raw materials and to perform 
their  obligations  under  agreements  with  us,  which  could  disrupt  our  operations.  Although  we  monitor  our  distributors’, 
customers’  and  suppliers’  financial  condition  and  their  liquidity  to  mitigate  our  business  risks,  some  of  our  distributors, 
customers and suppliers may become insolvent, which could have a material adverse effect on our product sales, business and 
results of operations. A significant worsening of global economic conditions could precipitate or materially amplify the other 
risks described herein.

We  maintain  a  significant  portfolio  of  investments  disclosed  as  cash  equivalents  and  marketable  securities  on  our 
consolidated  balance  sheets.  The  global  spread  of  COVID-19  has  also  led  to  disruption  and  volatility  in  the  global  capital 
markets. We have certain assets, including equity investments, that are exposed to market fluctuations that could, in a sustained 

50

or recurrent series of market disruptions, result in impairments. The value of our investments may also be adversely affected by 
interest  rate  fluctuations,  inflation,  downgrades  in  credit  ratings,  illiquidity  in  the  capital  markets  and  other  factors  that  may 
result  in  other-than-temporary  declines  in  the  value  of  our  investments.  Any  of  those  events  could  cause  us  to  record 
impairment charges with respect to our investment portfolio or to realize losses on sales of investments.

Our stock price is volatile.

Our stock price, like that of our peers in the biotechnology and pharmaceutical industries, is volatile. Our revenues and 
operating results may fluctuate from period to period for a number of reasons. Events such as a delay in product development, 
changes to our expectations or strategy or even a relatively small revenue shortfall may cause financial results for a period to be 
below  our  expectations  or  projections.  As  a  result,  our  revenues  and  operating  results  and,  in  turn,  our  stock  price  may  be 
subject to significant fluctuations. Announcements or discussions, including via social media channels, of possible restrictive 
actions by government or private payers that would negatively affect our business or industry if ultimately enacted or adopted 
may  also  cause  our  stock  price  to  fluctuate,  whether  or  not  such  restrictive  actions  ever  actually  occur.  Similarly,  actual  or 
perceived  safety  issues  with  our  products  or  similar  products  or  unexpected  clinical  trial  results  can  have  an  immediate  and 
rapid effect on our stock price, whether or not our operating results are materially affected.

We may not be able to access the capital and credit markets on terms that are favorable to us, or at all.

The  capital  and  credit  markets  may  experience  extreme  volatility  and  disruption,  which  may  lead  to  uncertainty  and 
liquidity  issues  for  both  borrowers  and  investors.  For  example,  early  in  2020,  there  were  significant  disruptions  in  the 
commercial paper market and several borrowers were unable to obtain funding at normal rates or maturities, which resulted in a 
significant increase in draws of corporate credit lines with banks. Similarly, the bond markets experienced extreme volatility in 
terms of interest rates and credit spreads, with several days without new issuances of corporate bonds. We expect to access the 
capital markets, from time to time, to supplement our existing funds and cash generated from operations to satisfy our needs for 
working capital; capital expenditure and debt service requirements; our plans to pay dividends and repurchase stock; and other 
business  initiatives  we  strategically  plan  to  pursue,  including  acquisitions  (such  as  our  acquisition  of  Horizon)  and  licensing 
activities. In the event of adverse capital and credit market conditions, we may be unable to obtain capital market financing on 
similar favorable terms, or at all, which could have a material adverse effect on our business and results of operations or our 
ability to complete business acquisitions. Changes in credit ratings issued by nationally recognized credit-rating agencies could 
adversely affect our ability to obtain capital market financing and the cost of such financing and have an adverse effect on the 
market price of our securities.

Overview 

Amgen is a biotechnology company committed to unlocking the potential of biology for patients suffering from serious 
illnesses. A biotechnology pioneer since 1980, Amgen has grown to be one of the world’s leading independent biotechnology 
companies,  has  reached  millions  of  patients  around  the  world  and  is  developing  a  pipeline  of  medicines  with  breakaway 
potential.

Our  principal  products  are  ENBREL,  Prolia,  Otezla,  XGEVA,  Aranesp,  Nplate,  Repatha,  KYPROLIS,  Neulasta  and 
EVENITY. We also market a number of other products, including MVASI, Vectibix, BLINCYTO, EPOGEN, AMGEVITA, 
Aimovig,  Parsabiv,  KANJINTI,  LUMAKRAS/LUMYKRAS,  TEZSPIRE,  NEUPOGEN,  Sensipar/Mimpara  and  TAVNEOS. 
For  additional  information  about  our  products,  see  Part  I,  Item  1.  Business—Marketing,  Distribution  and  Selected  Marketed 
Products.

Our strategy includes integrated activities intended to strengthen our competitive position in the industry. We operate in 
six  commercial  areas:  inflammation,  oncology/hematology,  bone  health,  cardiovascular  (CV)  disease,  nephrology  and 
neuroscience.  We  conduct  discovery  research  primarily  in  three  therapeutic  areas:  inflammation,  oncology/hematology  and 
general  medicine.  In  2022,  we  advanced  our  innovative  pipeline,  grew  our  international  business,  completed  a  strategic 
transaction  to  augment  our  marketed  product  portfolio,  announced  our  intention  to  acquire  Horizon  and  continued  providing 
uninterrupted supplies of our medicines globally through the third year of the COVID-19 pandemic. We accomplished these 
objectives while maintaining a strategic and disciplined approach to capital allocation and advancing our ESG efforts.

In  2022,  we  continued  to  advance  our  pipeline,  initiating  phase  3  clinical  trials  for  a  number  of  programs,  including 
LUMAKRAS/LUMYKRAS  for  advanced  colorectal  cancer,  olpasiran  for  CV  disease  and  rocatinlimab  for  atopic  dermatitis. 
We continued to grow our international business, including achieving key regulatory approvals for TEZSPIRE in the EU and 
Japan.  Our  external  business  development  activities  for  2022  included  the  acquisition  of  ChemoCentryx,  adding  recently 
launched  TAVNEOS  to  our  inflammation  portfolio.  We  also  continued  to  advance  our  biosimilar  program,  with  launches  in 
new markets. Our biosimilars are expected to continue launching in new markets throughout 2023, including the U.S. launch of 
AMJEVITA in January 2023.

During 2022, while gradually recovering from the global pandemic and facing increased competition from biosimilars and 
generics, total product sales increased 2%, primarily driven by volume growth for certain brands, partially offset by declines in 
net selling prices of certain products and unfavorable changes to foreign currency exchange rates. Product sales increased 3% in 
the  United  States,  primarily  driven  by  volume  growth,  partially  offset  by  declines  in  net  selling  prices,  and  increased  1%  in 
ROW,  primarily  driven  by  volume  growth,  partially  offset  by  unfavorable  changes  to  foreign  currency  exchange  rates  and 
declines in net selling prices. Total operating expenses decreased 9% due to both the acquired IPR&D write-off from the Five 
Prime  acquisition  and  a  licensing-related  upfront  payment  to  KKC  in  2021,  partially  offset  by  a  loss  on  a  nonstrategic 
divestiture in 2022.

Cash  flows  from  operating  activities  totaled  $9.7  billion,  which  supported  investment  in  our  business  while  returning 
capital to shareholders through the payment of cash dividends and stock repurchases. For 2022, we increased our quarterly cash 
dividend by 10% to $1.94 per share of common stock. In December 2022, we declared a cash dividend of $2.13 per share of 
common stock for the first quarter of 2023, an increase of 10% for this period, to be paid in March 2023. We also repurchased 
26.1 million shares of our common stock during 2022 at an aggregate cost of $6.3 billion. In 2022, we received net proceeds 
from  the  issuance  of  debt  of  $6.9  billion  and  extinguished  $0.3  billion  of  debt.  In  December  2022,  in  connection  with  the 
proposed acquisition of Horizon, we entered into a bridge credit agreement and a term loan credit agreement which provide for 
borrowings in the aggregate of $28.5 billion.

Amgen’s  approach  to  and  investment  in  human  capital  resource  management  is  directed  at  attracting,  motivating, 
developing  and  retaining  talent  to  tackle  the  challenges  of  running  an  enterprise  focused  on  the  discovery,  development  and 
commercialization of innovative medicines. Our compensation, benefits and development programs are designed to encourage 
performance,  promote  accountability  and  adherence  to  Company  values,  and  align  with  the  interests  of  the  Company’s 
shareholders.  Further,  we  believe  that  a  diverse  and  inclusive  culture  fosters  innovation,  which  supports  our  ability  to  serve 
patients. We are engaging in activities and setting goals to improve our focus on diversity, inclusion and belonging. For further 
information on these and other efforts, see Part I, Item 1. Business—Human Capital Resources.

We have a long-standing ambition to be environmentally responsible, and we regularly set targets to challenge ourselves 
to  deliver  further  improvements.  We  achieved  our  targets  for  the  2013–2020  period  while  growing  revenues,  increasing 
production  capacity  and  expanding  to  approximately  100  countries  over  the  same  period.  To  continue  on  our  path  to  greater 
environmental sustainability, in January 2021 we announced a new set of long-term environmental targets to achieve by 2027, 
including  achieving  carbon  neutrality,  reducing  water  consumption  by  40%  and  reducing  waste  disposed  by  75%.(1)(2) 
Additionally,  in  2022  we  issued  our  first  green  bonds  to  finance  eligible  projects  that  meet  specified  criteria  to  reduce  our 
impact on the environment.

Our  long-term  success  depends,  to  a  great  extent,  on  our  ability  to  continue  to  discover,  develop  and  commercialize 
innovative  products  and  acquire  or  collaborate  on  therapies  currently  in  development  by  other  companies.  We  must  develop 
new  products  to  achieve  revenue  growth  and  to  offset  revenue  losses  from  when  products  lose  their  exclusivity  or  when 
competing products are launched. Certain of our products face increasing pressure from competition, including biosimilars and 
generics. For additional information, including information on the expirations of patents for various products, see Part I, Item 1. 
Business—Marketing,  Distribution  and  Selected  Marketed  Products—Patents,  and  Part  I,  Item  1.  Business—Marketing, 
Distribution  and  Selected  Marketed  Products—Competition.  We  devote  considerable  resources  to  R&D  activities,  but 
successful product development in the biotechnology industry is highly uncertain. We also face increasing regulatory scrutiny 
of safety and efficacy both before and after products launch.

Rising  healthcare  costs,  uncertain  macroeconomic  conditions,  including  higher  inflation  and  rising  interest  rates,  and 
geopolitical conflicts continue to pose challenges to our business. As a result of public and private healthcare-provider focus, 
the industry continues to be subject to cost containment measures and significant pricing pressures, including net price declines. 
Moreover, legislation enacted to reduce healthcare expenditures, including provisions of the IRA, have affected, and are likely 
to continue to affect, our business. Finally, wholesale and end-user buying patterns can affect our product sales. These buying 
patterns can cause fluctuations in quarterly product sales but have generally not been significant to date when comparing full-
year  product  performance  to  the  prior  year.  See  Part  I,  Item  1.  Business—Marketing,  Distribution  and  Selected  Marketed 
Products, and Part I, Item 1A. Risk Factors for further discussion of certain factors that could impact our future product sales.

COVID-19 pandemic

Since  the  onset  of  the  pandemic  in  2020,  we  have  been  closely  monitoring  the  pandemic’s  effects  on  our  global 
operations.  We  continue  to  take  appropriate  steps  to  minimize  risks  to  our  employees,  a  significant  number  of  whom  have 
continued to work virtually. To date, our remote working arrangements have not significantly affected our ability to maintain 
critical business operations, and we have not experienced disruptions to or shortages of our supply of medicines.

Over the course of the pandemic we have experienced changes in demand for some of our products as fluctuations in the 
frequency  of  patient  visits  to  doctors’  offices  have  impacted  the  provision  of  treatments  to  existing  patients  and  reduced 
diagnoses in new patients. During 2021, there was a gradual recovery in both patient visits and diagnosis rates that approached 
pre-pandemic  levels.  In  2022,  the  pandemic  continued  to  impact  the  healthcare  sector  and  our  business,  to  varying  degrees 
across our markets. During 2022, with the exception of the Asia Pacific region that was affected by lockdowns during most of 
the year, we saw greater stability in patient visits and demand patterns even in areas that were facing surges in the virus. Given 
the evolution of COVID-19 since its onset, including the proliferation of variants, we cannot predict the impact of future virus 
surges  on  our  business  and  will  continue  to  closely  monitor  the  impact  of  COVID-19  on  our  business  and  on  the  healthcare 
sector more generally.

Since early 2021, efforts have been under way to control the COVID-19 pandemic. However, uncertainty remains as to 
the efficacy of these activities with respect to the ongoing trajectory of the pandemic. Challenges to vaccination efforts, new 
variants  and  other  causes  of  virus  spread  may  require  governments  to  change  restrictions  and/or  shutdown  requirements  in 
various geographies. As a result, we expect to see continued volatility for at least the duration of the pandemic as governments 
respond to current local conditions. 

With regard to our clinical trial activities, we are continuously monitoring COVID-19 infection rates, including changes 
from new variants; we are working to mitigate effects on future study enrollment in our clinical trials; and we are evaluating the 
impact in all relevant countries. We remain focused on supporting our active clinical sites in their providing care for patients 
and in our providing investigational drug supply. For a discussion of the risks the COVID-19 pandemic could present to our 
results, see Part I, Item 1A. Risk Factors of this Form 10-K.

In the following discussion of changes in product sales, any reference to volume growth or decline refers to changes in the 
purchases  of  our  products  by  healthcare  providers  (such  as  physicians  or  their  clinics),  dialysis  centers,  hospitals  and 
pharmacies. In addition, any reference to increases or decreases in inventory refers to changes in inventory held by wholesaler 
customers and end users (such as pharmacies).

Total product sales increased in 2022, primarily driven by volume growth for certain brands, including Repatha, Prolia, 
EVENITY, Nplate, LUMAKRAS/LUMYKRAS, KYPROLIS, Otezla and TEZSPIRE, partially offset by declines in net selling 
prices  of  certain  products,  including  Neulasta,  Repatha  and  MVASI,  and  unfavorable  changes  to  foreign  currency  exchange 
rates. For 2023, we expect that net selling prices will continue to decline at a portfolio level driven by increased competition. 
Further,  the  first  quarter  of  a  year  historically  represents  the  lowest  product  sales  quarter  for  the  year,  in  part  due  to  plan 
changes,  insurance  reverifications  and  higher  co-pay  expenses  as  U.S.  patients  work  through  deductibles,  particularly  for 
products acquired through pharmacy benefit programs.

As  a  result  of  uncertain  macroeconomic  conditions,  we  expect  volatility  around  foreign  currency  exchange  rates  to 
continue.  The  impact  of  unfavorable  changes  to  foreign  currency  exchange  rates  will  be  partially  offset  by  corresponding 
decreases  in  our  international  operating  expenses.  While  not  designed  to  completely  address  foreign  currency  changes,  our 
hedging  activities  also  seek  to  offset,  in  part,  such  effects  on  our  net  income  by  hedging  our  net  foreign  currency  exposure, 
primarily with respect to product sales denominated in euros.

As discussed above, our product sales have been affected by reduced demand as a result of the COVID-19 pandemic. In 
general, the dynamics of the pandemic were most significant on our product sales in the early months of the pandemic, with 
demand beginning to show some recovery in late 2020. In late 2021 and early 2022, increased infection rates caused by variants 
of the virus (including Omicron) led to diminished capacity in the healthcare sector and reduced working days for our own sales 
force,  which  impacted  our  business.  As  of  the  second  quarter  of  2022,  we  saw  the  effects  of  these  variants  recede  in  most 
markets, which allowed us to engage in increased field-facing activities. Provider and patient activity also increased, leading to 
improvements  in  demand  for  our  products  to  pre-pandemic  levels.  However,  the  cumulative  decrease  in  diagnoses  over  the 
course of the pandemic has suppressed the volume of new patients starting treatment, which continues to impact our business. 
Given the unpredictable nature of the pandemic, there could be intermittent disruptions in physician–patient interactions, and as 
a  result,  we  may  experience  quarter-to-quarter  variability.  In  addition,  other  changes  in  the  healthcare  ecosystem  have  the 
potential to introduce variability into product sales trends. For example, changes in U.S. employment have led to changes to the 
insured population. Growth in numbers of Medicaid enrollees and uninsured individuals, along with provisions of the IRA, may 
have a negative impact on product sales. Overall, uncertainty remains around the timing and magnitude of our sales during the 
COVID-19 pandemic. See Risk Factors in Part I, Item 1A. of this Form 10-K.

Other  revenues  decreased  for  2022,  driven  by  lower  revenue  from  COVID-19  antibody  material  and  licensing-related 

revenues.

Operating expenses decreased for 2022 due to both the acquired IPR&D write-off related to the bemarituzumab program 
acquired as part of the Five Prime acquisition and a licensing-related upfront payment to KKC in 2021, partially offset by a loss

The  decrease  in  ENBREL  sales  for  2022  was  primarily  driven  by  unfavorable  changes  to  estimated  sales  deductions, 
lower volume and lower net selling price. For 2023, we expect ENBREL to follow the historical pattern of lower sales in the 
first quarter relative to subsequent quarters due to the impact of benefit plan changes, insurance reverification and increased co-
pay expenses as U.S. patients work through deductibles. In addition, for 2023, we expect further declines in net selling price.

The  decrease  in  ENBREL  sales  for  2021  was  driven  by  lower  net  selling  price,  volume  and  unfavorable  changes  to

Research and development

The  Company  groups  all  of  its  R&D  activities  and  related  expenditures  into  three  categories:  (i)  research  and  early 

pipeline, (ii) later-stage clinical programs and (iii) marketed products. These categories are described below:

Category

Research and early pipeline 

Later-stage clinical programs

Marketed products

Description
R&D  expenses  incurred  in  activities  substantially  in  support  of  early  research 
through  the  completion  of  phase  1  clinical  trials,  including  drug  discovery, 
toxicology, pharmacokinetics and drug metabolism and process development

R&D  expenses  incurred  in  or  related  to  phase  2  and  phase  3  clinical  programs 
intended  to  result  in  registration  of  a  new  product  or  a  new  indication  for  an 
existing product primarily in the United States or the EU

R&D  expenses  incurred  in  support  of  the  Company’s  marketed  products  that  are 
authorized  to  be  sold  primarily  in  the  United  States  or  the  EU.  Includes  clinical 
trials  designed  to  gather  information  on  product  safety  (certain  of  which  may  be 
required by regulatory authorities) and their product characteristics after regulatory 
approval has been obtained, as well as the costs of obtaining regulatory approval of 
a product in a new market after approval in either the United States or the EU has 
been obtained

The  decrease  in  R&D  expense  for  2022  was  driven  by  higher  business  development  activity  in  2021  included  in  later-
stage clinical programs and research and early pipeline and lower marketed products support, partially offset by higher later-
stage clinical programs support and research and early pipeline spend.

The increase in R&D expense for 2021 was driven by a licensing-related upfront payment to KKC included in later-stage 

clinical programs and higher spend in research and early pipeline, including other business development activities.

Acquired in-process research and development

The Acquired IPR&D expense in 2021 was related to the bemarituzumab program, which was acquired as part of the Five 

Prime acquisition in 2021. See Part IV—Note 2, Acquisitions and divestitures, to the Consolidated Financial Statements.

Selling, general and administrative

The increase in SG&A expense for 2022 was primarily driven by higher acquisition-related expenses.

The decrease in SG&A expense for 2021 was primarily driven by lower spend for marketed products and lower general 

and administrative expenses.

Other

Other  operating  expenses  for  2022  primarily  consisted  of  a  loss  on  a  nonstrategic  divestiture.  See  Part  IV—Note  2, 

Acquisitions and divestitures, to the Consolidated Financial Statements.

Other operating expenses for 2021 primarily consisted of expenses related to cost-savings initiatives and a legal judgment.

The increase in Interest expense, net, for 2022 was primarily due to higher overall debt outstanding and higher LIBORs on 

debt for which we effectively pay a variable rate of interest through the use of interest rate swaps.

The decrease in Interest expense, net, for 2021 was primarily due to net higher costs associated with the early retirement 
of debt in 2020 and lower LIBORs in 2021 on debt for which we effectively pay a variable rate of interest through the use of 
interest rate swaps, partially offset by higher overall debt outstanding.

65

 
 
 
 
 
 
Other (expense) income, net

The change in Other (expense) income, net, for 2022 was primarily due to higher losses recognized in connection with our 
BeiGene  investment  compared  with  2021  and  losses  recognized  on  our  investments  in  limited  partnerships,  publicly  traded 
equity securities and other strategic investments.

The change in Other (expense) income, net, for 2021 was primarily due to lower losses incurred in connection with our 
BeiGene  investment  compared  with  2020,  partially  offset  by  lower  income  on  our  interest-bearing  investments  in  2021  and 
other nonrecurring gains recognized in 2020.

Income taxes

The  decrease  in  our  effective  tax  rate  for  2022  compared  with  2021  was  primarily  due  to  the  nondeductible  IPR&D 
expense arising from the acquisition of Five Prime in the prior year, partially offset by a nondeductible loss on a nonstrategic 
divestiture in 2022 and net unfavorable items as compared to the prior year.

The increase in our effective tax rate for 2021 compared with 2020 was primarily driven by the nondeductible IPR&D 

expense arising from the acquisition of Five Prime, partially offset by earnings mix and adjustments to prior-year tax liabilities.

The  Administration  and  Congress  continue  to  discuss  changes  to  existing  tax  law  that  could  substantially  increase  the 
taxes  we  pay  to  the  U.S.  government.  Further,  the  OECD  recently  reached  an  agreement  to  align  countries  on  a  minimum 
corporate  tax  rate  and  an  expansion  of  the  taxing  rights  of  market  countries.  If  enacted,  either  by  all  OECD  participants  or 
unilaterally  by  individual  countries,  this  agreement  could  result  in  a  tax  increase  that  could  affect  our  U.S.  and  foreign  tax 
liabilities. 

The U.S. Treasury released final foreign tax credit regulations in December 2021 that eliminated U.S. creditability of the 
Puerto Rico Excise Tax beginning in 2023, which would have increased our U.S. tax liability. In response, on June 30, 2022, 
the U.S. territory of Puerto Rico enacted Act 52-2022, which provides for an alternate fixed tax rate on industrial development 
income that the U.S. Treasury confirmed will be creditable under federal law. As part of this new law, eligible businesses will 
be subject to incremental income and withholding taxes in lieu of payment of the Puerto Rico Excise Tax. In order to qualify 
for the alternative fixed tax rate, our current tax grant with the Puerto Rico government was amended in December 2022. We 
qualify for this alternative fixed tax rate, beginning January 1, 2023 and our tax expense will increase. 

In  2017,  we  received  an  RAR  and  a  modified  RAR  from  the  IRS  for  the  years  2010–2012,  proposing  significant 
adjustments  that  primarily  relate  to  the  allocation  of  profits  between  certain  of  our  entities  in  the  United  States  and  the  U.S. 
territory  of  Puerto  Rico.  We  disagreed  with  the  proposed  adjustments  and  calculations  and  pursued  resolution  with  the  IRS 
appeals  office  but  were  unable  to  reach  resolution.  In  July  2021,  we  filed  a  petition  in  the  U.S.  Tax  Court  to  contest  two 
duplicate Statutory Notices of Deficiency (Notices) for the years 2010–2012 that we received in May and July 2021, which seek 
to  increase  our  U.S.  taxable  income  for  the  years  2010–2012  by  an  amount  that  would  result  in  additional  federal  tax  of 
approximately $3.6 billion plus interest. Any additional tax that could be imposed for the years 2010–2012 would be reduced 
by up to approximately $900 million of repatriation tax previously accrued on our foreign earnings. 

In  2020,  we  received  an  RAR  and  a  modified  RAR  from  the  IRS  for  the  years  2013–2015,  also  proposing  significant 
adjustments  that  primarily  relate  to  the  allocation  of  profits  between  certain  of  our  entities  in  the  United  States  and  the  U.S. 
territory of Puerto Rico similar to those proposed for the years 2010–2012. We disagreed with the proposed adjustments and 
calculations and pursued resolution with the IRS appeals office but were unable to reach resolution. In July 2022, we filed a 
petition in the U.S. Tax Court to contest a Notice for the years 2013–2015 that we previously reported receiving in April 2022 
that seeks to increase our U.S. taxable income for the years 2013–2015 by an amount that would result in additional federal tax 
of  approximately  $5.1  billion,  plus  interest.  In  addition,  the  Notice  asserts  penalties  of  approximately  $2.0  billion.  Any 
additional  tax  that  could  be  imposed  for  the  years  2013–2015  would  be  reduced  by  up  to  approximately  $2.2  billion  of 
repatriation tax previously accrued on our foreign earnings. 

We firmly believe that the IRS positions set forth in the 2010–2012 and 2013–2015 Notices are without merit. We are 
contesting the 2010–2012 and 2013–2015 Notices through the judicial process. The two cases were consolidated in U.S. Tax 
Court on December 19, 2022.

We  are  currently  under  examination  by  the  IRS  for  the  years  2016–2018  with  respect  to  issues  similar  to  those  for  the 

2010 through 2015 period. In addition, we are under examination by a number of state and foreign tax jurisdictions.

Final resolution of these complex matters is not likely within the next 12 months. We continue to believe our accrual for 
income tax liabilities is appropriate based on past experience, interpretations of tax law, application of the tax law to our facts 
and judgments about potential actions by tax authorities; however, due to the complexity of the provision for income taxes and 

66

uncertain resolution of these matters, the ultimate outcome of any tax matters may result in payments substantially greater than 
amounts accrued and could have a material adverse impact on our consolidated financial statements.

See Part I, Item 1A. Risk Factors—The adoption and interpretation of new tax legislation or exposure to additional tax 
liabilities  could  affect  our  profitability;  Part  II,  Item  7.  Management’s  Discussion  and  Analysis  or  Financial  Condition  and 
Results of Operations—Critical Accounting Policies and Estimates, Income taxes; and Part IV—Note 6, Income taxes, to the 
Consolidated Financial Statements for further discussion.

Our  balance  of  cash,  cash  equivalents  and  marketable  securities  was  $9.3  billion  at  December  31,  2022.  The  primary 
objective of our investment portfolio is to maintain safety of principal, prudent levels of liquidity and acceptable levels of risk. 
Our investment policy limits interest-bearing security investments to certain types of debt and money market instruments issued 
by institutions with primarily investment-grade credit ratings, and it places restrictions on maturities and concentration by asset 
class and issuer.

Capital allocation

Consistent  with  the  objective  to  optimize  our  capital  structure,  we  deploy  our  accumulated  cash  balances  in  a  strategic 
manner  and  consider  a  number  of  alternatives,  including  investments  in  innovation,  both  internally  and  externally,  strategic 
transactions (including those that expand our portfolio of products in areas of therapeutic interest), repayment of debt, payment 
of dividends and stock repurchases.

  We  intend  to  continue  investing  in  our  business  while  returning  capital  to  stockholders  through  the  payment  of  cash 
dividends and stock repurchases, thereby reflecting our confidence in the future cash flows of our business and our desire to 
optimize our cost of capital. The timing and amount of future dividends and stock repurchases will vary based on a number of 
factors,  including  future  capital  requirements  for  strategic  transactions,  availability  of  financing  on  acceptable  terms,  debt 
service  requirements,  our  credit  rating,  changes  to  applicable  tax  laws  or  corporate  laws,  changes  to  our  business  model  and 
periodic  determination  by  our  Board  of  Directors  that  cash  dividends  and/or  stock  repurchases  are  in  the  best  interests  of 
stockholders and are in compliance with applicable laws and the Company’s agreements. In addition, the timing and amount of 
stock  repurchases  may  also  be  affected  by  our  overall  level  of  cash,  stock  price  and  blackout  periods,  during  which  we  are 
restricted  from  repurchasing  stock.  The  manner  of  stock  repurchases  may  include  block  purchases,  tender  offers,  accelerated 
share repurchases and market transactions.

The Board of Directors declared quarterly cash dividends of $1.94, $1.76 and $1.60 per share of common stock paid in 
2022, 2021 and 2020, respectively, an increase of 10% over the prior year in both 2022 and 2021. In December 2022, the Board 
of Directors declared a cash dividend of $2.13 per share of common stock for the first quarter of 2023, an increase of 10% for 
this period, to be paid in March 2023.

We also returned capital to stockholders through our stock repurchase program. During 2022, we repurchased $6.3 billion 
of common stock, including $6.0 billion under ASR agreements and had cash settlements for stock repurchases of $6.4 billion. 
In  2021,  we  repurchased  and  had  cash  settlements  of  $5.0  billion  of  common  stock.  In  2020,  we  repurchased  and  had  cash 
settlements of $3.5 billion of common stock. In October 2022, the Board of Directors increased the amount authorized under 
our  stock  repurchase  program  by  $2.4  billion.  As  of  December  31,  2022,  $7.0  billion  remained  available  under  the  stock 
repurchase program.

67

As  a  result  of  stock  repurchases  and  quarterly  dividend  payments,  we  have  an  accumulated  deficit  as  of  December  31, 
2022 and 2021. Our accumulated deficit is not anticipated to affect our future ability to operate, repurchase stock, pay dividends 
or repay our debt given our expected continued profitability and strong financial position.

We  believe  that  existing  funds,  cash  generated  from  operations  and  existing  sources  of  and  access  to  financing  are 
adequate to satisfy our needs for working capital, capital expenditure and debt service requirements, our plans to pay dividends 
and  repurchase  stock,  and  other  business  initiatives  we  plan  to  strategically  pursue,  including  acquisitions  and  licensing 
activities. We anticipate that our liquidity needs can be met through a variety of sources, including cash provided by operating 
activities, sales of marketable securities, borrowings through commercial paper and/or syndicated credit facilities, and access to 
other domestic and foreign debt markets and equity markets. See Part I, Item 1A. Risk Factors—Global economic conditions 
may negatively affect us and may magnify certain risks that affect our business.

Financing arrangements

To help meet our liquidity requirements, we have entered into various financing arrangements. The noncurrent portions of 
our long-term borrowings as of December 31, 2022 and 2021, were $37.4 billion and $33.2 billion, respectively. The carrying 
values  of  our  long-term  borrowings  are  net  of  fair  value  adjustments  for  interest  rate  swaps  and  unamortized  discounts, 
premiums  and  offering  costs.  As  of  December  31,  2022,  S&P,  Moody’s  and  Fitch  assigned  credit  ratings  to  our  outstanding 
senior  notes  of  BBB+,  Baa1  and  BBB+,  respectively,  which  are  considered  investment  grade.  Unfavorable  changes  to  these 
ratings may have an adverse impact on future financings.

During  2022,  2021  and  2020,  we  issued  debt  with  aggregate  principal  amounts  of  $7.0  billion,  $5.0  billion  and  $9.0 
billion,  respectively.  During  2022,  we  repurchased  portions  of  our  debt  at  a  cost  of  $0.3  billion.  During  2021  and  2020,  we 
repaid/redeemed  debt  of  $4.2  billion  and  $6.5  billion,  respectively.  In  addition,  during  2020,  we  exchanged  $0.7  billion  of 
certain of our outstanding note issuances with $0.9 billion of newly issued notes with a lower interest rate and later maturity 
date.

To achieve a desired mix of fixed-rate and floating-rate debt, we entered into interest rate swap contracts that effectively 
converted a fixed-rate interest coupon for certain of our debt issuances to a floating, LIBOR-based coupon over the lives of the 
respective notes. These interest rate swap contracts qualify and are designated as fair value hedges. As of both December 31, 
2022 and 2021, we had interest rate swap contracts with aggregate notional amount of $6.7 billion.

To hedge our exposure to foreign currency exchange rate risk associated with certain of our long-term notes denominated 
in  foreign  currencies,  we  entered  into  cross-currency  swap  contracts,  which  effectively  convert  the  interest  payments  and 
principal repayment of the respective notes from euros, pounds sterling and Swiss francs to U.S. dollars. These cross-currency 
swap contracts qualify and are designated as cash flow hedges. As of both December 31, 2022 and 2021, we had cross-currency 
swap contracts with aggregate notional amount of $3.4 billion.

As of December 31, 2022, we had a commercial paper program that allows us to issue up to $2.5 billion of unsecured 
commercial paper to fund our working-capital needs. During 2022, 2021 and 2020, we did not issue any commercial paper. No 
commercial paper was outstanding as of December 31, 2022 and 2021.

In 2019, we amended and restated our $2.5 billion syndicated, unsecured, revolving credit agreement, which is available 
for  general  corporate  purposes  or  as  a  liquidity  backstop  to  our  commercial  paper  program.  The  commitments  under  the 
revolving credit agreement may be increased by up to $750 million with the agreement of the banks. Each bank that is a party to 
the  agreement  has  an  initial  commitment  term  of  five  years.  This  term  may  be  extended  for  up  to  two  additional  one-year 
periods  with  the  agreement  of  the  banks.  Annual  commitment  fees  for  this  agreement  are  0.1%  of  the  unused  portion  of  the 
facility based on our current credit rating. In December 2022, this revolving credit agreement was further amended to replace 
LIBOR with SOFR as the reference rate, pursuant to provisions contained therein related to determination of successor rates in 
case  of  phaseout  or  unavailability  of  existing  designated  reference  rates.  Generally,  we  would  be  charged  interest  for  any 
amounts borrowed under this facility, based on our current credit rating, at (i) SOFR plus 1.125% or (ii) the highest of (A) the 
syndication agent bank base commercial lending rate, (B) the overnight federal funds rate plus 0.50% or (C) one-month SOFR 
plus 1.1%. As of December 31, 2022 and 2021, no amounts were outstanding under this facility.

In December 2022, in connection with the proposed acquisition of Horizon, we entered into a bridge credit agreement and 
a  term  loan  credit  agreement  which  provide  for  borrowings  in  the  aggregate  of  $28.5  billion.  As  of  December  31,  2022,  no 
amounts have been borrowed under either agreement. See Part IV—Note 2, Acquisitions and divestitures, to the Consolidated 
Financial Statements.

68

It is anticipated that the U.S. dollar LIBOR rate will be phased out and replaced by 2023. The Alternative Reference Rates 
Committee, a group of private-market participants convened by the Federal Reserve Board and the Federal Reserve Bank of 
New York to help ensure a successful transition from U.S. dollar LIBOR to a more robust reference rate, recommends SOFR as 
the  U.S.  dollar  LIBOR  alternative.  As  such,  we  expect  SOFR  to  become  widely  adopted  by  market  participants.  We  do  not 
expect this change to have a material impact on our consolidated financial statements. See Part I, Item 1A. Risk Factors—Our 
sales and operations are subject to the risks of doing business internationally, including in emerging markets.

In February 2020, we filed a shelf registration statement with the SEC that allows us to issue unspecified amounts of debt 
securities; common stock; preferred stock; warrants to purchase debt securities, common stock, preferred stock or depositary 
shares;  rights  to  purchase  common  stock  or  preferred  stock;  securities  purchase  contracts;  securities  purchase  units;  and 
depositary shares. Under this shelf registration statement, all of the securities available for issuance may be offered from time to 
time with terms to be determined at the time of issuance. This shelf registration statement expires in February 2023, and our 
Board has approved a new shelf registration statement to replace it.

Certain of our financing arrangements contain nonfinancial covenants. In addition, our revolving credit agreement, bridge 
credit agreement and term loan credit agreement include a financial covenant that requires us to maintain a specified minimum 
interest  coverage  ratio  of  (i)  the  sum  of  consolidated  net  income,  interest  expense,  provision  for  income  taxes,  depreciation 
expense,  amortization  expense,  unusual  or  nonrecurring  charges  and  other  noncash  items  (Consolidated  EBITDA)  to  (ii) 
Consolidated  Interest  Expense,  each  as  defined  and  described  in  the  respective  agreements.  We  were  in  compliance  with  all 
applicable covenants under these arrangements as of December 31, 2022.

  These  financing  arrangements  are  more  fully  discussed  in  Part  IV—Note  15,  Financing  arrangements,  and  Note  18, 

Derivative instruments, to the Consolidated Financial Statements.

Cash flows

Our summarized cash flow activity was as follows (in millions):

Net cash (used in) provided by investing activities

Net cash used in financing activities

(4,867) 

Cash provided by operating activities has been and is expected to continue to be our primary recurring source of funds. 
Cash  provided  by  operating  activities  increased  in  2022  primarily  due  to  the  timing  of  payments  for  sales  incentives  and 
discounts,  vendor  purchases,  liabilities  to  tax  authorities  and  receipts  from  corporate  partners,  partially  offset  by  higher 
manufacturing activities in the current year. Cash provided by operating activities decreased during 2021 primarily due to the 
monetization of interest rate swaps that occurred in 2020 and the timing of payments for sales incentives and discounts.

Investing

Cash used in investing activities during 2022 was primarily due to our $3.8 billion purchase of ChemoCentryx and net 
cash outflows related to marketable securities of $1.4 billion. Cash provided by investing activities during 2021 was primarily 
due  to  net  cash  inflows  related  to  marketable  securities  of  $4.3  billion,  partially  offset  by  cash  used  in  the  acquisitions  of 
Teneobio and Five Prime of $2.5 billion. Cash used in investing activities during 2020 was primarily due to our $3.2 billion of 
purchases  of  equity  method  investments,  primarily  BeiGene,  and  net  cash  outflows  related  to  marketable  securities  of  $1.5 
billion.  Capital  expenditures  were  $936  million,  $880  million  and  $608  million  in  2022,  2021  and  2020,  respectively.  We 
currently  estimate  2023  spending  on  capital  projects  to  be  approximately  $925  million.  A  majority  of  the  increase  in 
expenditures relates to expansion of manufacturing capacity to enable supply of products and product candidates.

69

Financing

Cash  used  in  financing  activities  during  2022  was  primarily  due  to  payments  to  repurchase  our  common  stock  of 
$6.4 billion and dividends paid of $4.2 billion, partially offset by proceeds from the issuance of debt of $6.9 billion. Cash used 
in  financing  activities  during  2021  was  primarily  due  to  payments  to  repurchase  our  common  stock  of  $5.0  billion  and  the 
payment of dividends of $4.0 billion, partially offset by proceeds from the issuance of debt, net of repayments of $0.8 billion. 
Cash used in financing activities during 2020 was primarily due to the payment of dividends of $3.8 billion and payments to 
repurchase  our  common  stock  of  $3.5  billion,  partially  offset  by  proceeds  from  issuance  of  debt,  net  of  repayments  of  $2.5 
billion.

See  Part  IV—Note  9,  Investments;  Note  15,  Financing  arrangements;  and  Note  16,  Stockholders’  equity,  to  the 

Consolidated Financial Statements.

Capital requirements

We have material cash requirements to pay third parties under various contractual obligations discussed below.

We are obligated to pay interest and repay principal under our various financing arrangements, including amounts under 
interest  rate  swap  and  cross-currency  swap  contracts  related  to  certain  of  our  long-term  debt  obligations.  For  information  on 
scheduled debt maturities and payments under derivative contracts associated with our long-term debt obligations, see Part IV
—Note 15, Financing arrangements, and Note 18, Derivative instruments, to the Consolidated Financial Statements.

We are obligated to make payments for operating leases, including rental commitments on abandoned leases and leases 
that  have  not  yet  commenced.  For  information  on  these  obligations,  see  Part  IV—Note  13,  Leases,  to  the  Consolidated 
Financial Statements.

Under  the  2017  Tax  Act,  we  elected  to  pay  in  eight  annual  installments  the  repatriation  tax  related  primarily  to  prior 
indefinitely  invested  earnings  of  our  foreign  operations.  For  information  on  the  remaining  scheduled  repatriation  tax 
installments,  see  Part  IV—Note  19,  Contingencies  and  commitments—Commitments—U.S.  repatriation  tax,  to  the 
Consolidated Financial Statements.

We  have  purchase  obligations  of  $3.5  billion  primarily  related  to  (i)  R&D  commitments  (including  those  related  to 
clinical trials) for new and existing products, (ii) capital expenditures and (iii) open purchase orders for the acquisition of goods 
and services in the ordinary course of business. Most of these obligations are expected to be paid within one year, and payment 
of certain of these amounts may be reduced based on certain future events.

 In addition to the purchase obligations noted above, we are contractually obligated to pay additional amounts that in the 
aggregate are significant, upon the achievement of various development, regulatory and commercial milestones for agreements 
we have entered into with third parties, including contingent consideration incurred in the acquisitions of Teneobio and K-A. 
These payments are contingent upon the occurrence of various future events, substantially all of which have a high degree of 
uncertainty of occurring, and any resulting cash requirements are managed through our operational budgeting processes. Except 
with respect to the fair value of the contingent consideration of approximately $0.3 billion, these obligations are not recorded on 
our  Consolidated  Balance  Sheets.  As  of  December  31,  2022,  the  maximum  amount  that  may  be  payable  in  the  future  for 
agreements we have entered into with third parties is $5.6 billion.

We have recorded liabilities for UTBs that, because of their nature, have a high degree of uncertainty regarding the timing 
of future cash payment and other events that extinguish these liabilities. See Part IV—Note 6, Income taxes, to the Consolidated 
Financial Statements.

Critical Accounting Policies and Estimates

The  preparation  of  our  consolidated  financial  statements  in  conformity  with  GAAP  requires  management  to  make 
estimates and assumptions that affect the amounts reported in the financial statements and the notes to the financial statements. 
Some  of  those  judgments  can  be  subjective  and  complex,  and  therefore,  actual  results  could  differ  materially  from  those 
estimates  under  different  assumptions  or  conditions.  Our  significant  accounting  policies  are  included  in  Part  IV—Note  1, 
Summary  of  significant  accounting  policies.  The  following  are  considered  critical  to  our  consolidated  financial  statements 
because they require the most difficult, subjective or complex judgments, often because of the need to make estimates about 
matters that are inherently uncertain.

Product sales and sales deductions

Revenue from product sales is recognized upon transfer of control of a product to a customer, generally upon delivery, 
based  on  an  amount  that  reflects  the  consideration  to  which  we  expect  to  be  entitled,  net  of  accruals  for  estimated  rebates, 
wholesaler chargebacks, discounts and other deductions (collectively, sales deductions) and returns established at the time of 
sale.

We  analyze  the  adequacy  of  our  accruals  for  sales  deductions  quarterly.  Amounts  accrued  for  sales  deductions  are 
adjusted when trends or significant events indicate that adjustment is appropriate. Accruals are also adjusted to reflect actual 
results.  Amounts  recorded  in  Accrued  liabilities  in  the  Consolidated  Balance  Sheets  for  sales  deductions  were  as  follows  (in 
millions):

For the years ended December 31, 2022, 2021 and 2020, total sales deductions were 51%, 47% and 44% of gross product 
sales, respectively. The increase in the total sales deductions balance as of December 31, 2022, compared with December 31, 
2021, was primarily driven by the impact of higher U.S. chargeback and commercial rebate discount rates and an increase in 
gross sales, partially offset by timing of payments. Included in the amounts are immaterial net adjustments related to prior-year 
sales due to changes in estimates. 

In the United States, we use wholesalers as the principal means of distributing our products to healthcare providers such 
as physicians or their clinics, dialysis centers, hospitals and pharmacies. Products we sell in Europe are distributed principally 
to hospitals and/or wholesalers depending on the distribution practice in each country where the products are sold. We monitor 
the  inventory  levels  of  our  products  at  our  wholesalers  by  using  data  from  our  wholesalers  and  other  third  parties,  and  we 
believe  wholesaler  inventories  have  been  maintained  at  appropriate  levels  (generally  two  to  three  weeks)  given  end-user 
demand.  Accordingly,  historical  fluctuations  in  wholesaler  inventory  levels  have  not  significantly  affected  our  method  of 
estimating sales deductions and returns.

Accruals for sales deductions are based primarily on estimates of the amounts earned or to be claimed on the related sales. 
These  estimates  take  into  consideration  current  contractual  and  statutory  requirements,  specific  known  market  events  and 
trends, internal and external historical data and forecasted customer buying patterns. Sales deductions are substantially product 
specific and therefore, for any given year, can be affected by the mix of products sold.

Rebates  include  primarily  amounts  paid  to  payers  and  providers  in  the  United  States,  including  those  paid  to  state 
Medicaid programs, and are based on contractual arrangements or statutory requirements that vary by product, by payer and by 
individual payer plans. As we sell products, we estimate the amount of rebate we will pay based on the product sold, contractual 
terms, estimated patient population, historical experience and wholesaler inventory levels; and we accrue these rebates in the 
period the related sales are recorded. We then adjust the rebate accruals as more information becomes available and to reflect 

71

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
actual claims experience. Estimating such rebates is complicated, in part because of the time delay between the date of sale and 
the actual settlement of the liability. We believe the methodology we use to accrue for rebates is reasonable and appropriate 
given current facts and circumstances, but actual results may differ. 

Wholesaler chargebacks relate to our contractual agreements to sell products to healthcare providers in the United States 
at fixed prices that are lower than the prices we charge wholesalers. When healthcare providers purchase our products through 
wholesalers at these reduced prices, wholesalers charge us for the difference between their purchase prices and the contractual 
prices  between  Amgen  and  the  healthcare  providers.  The  provision  for  chargebacks  is  based  on  expected  sales  by  our 
wholesaler  customers  to  healthcare  providers.  Accruals  for  wholesaler  chargebacks  are  less  difficult  to  estimate  than  rebates 
are, and they closely approximate actual results because chargeback amounts are fixed at the date of purchase by the healthcare 
providers and because we generally settle the liability for these deductions within a few weeks.

Product returns

Returns  are  estimated  by  comparison  of  historical  return  data  to  their  related  sales  on  a  production  lot  basis.  Historical 
rates of return are determined for each product and are adjusted for known or expected changes in the marketplace specific to 
each product, when appropriate. In each of the past three years, sales return provisions have amounted to less than 1% of gross 
product sales. Changes in estimates for prior-year sales return provisions have historically been immaterial.

Income taxes

We  provide  for  income  taxes  based  on  pretax  income  and  applicable  tax  rates  in  the  various  jurisdictions  in  which  we 

operate.

We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be 
sustained upon examination by tax authorities based on the technical merits of the position. The tax benefit recognized in the 
consolidated financial statements for a particular tax position is based on the largest benefit that is more likely than not to be 
realized.  The  amount  of  UTBs  is  adjusted  as  appropriate  for  changes  in  facts  and  circumstances,  such  as  significant 
amendments to existing tax law, new regulations or interpretations by tax authorities, new information obtained during a tax 
examination or resolution of an examination. We believe our estimates for uncertain tax positions are appropriate and sufficient 
for  any  assessments  that  may  result  from  examinations  of  our  tax  returns.  We  recognize  both  accrued  interest  and  penalties, 
when appropriate, related to UTBs in income tax expense.

Certain items are included in our tax return at different times than they are reflected in the financial statements, and they 
cause  temporary  differences  between  the  tax  bases  of  assets  and  liabilities  and  their  reported  amounts.  Such  temporary 
differences create deferred tax assets and liabilities. Deferred tax assets are generally items that can be used as tax deductions or 
credits  in  tax  returns  in  future  years  but  for  which  we  have  already  recorded  the  tax  benefit  in  the  consolidated  financial 
statements.  We  establish  valuation  allowances  against  our  deferred  tax  assets  when  the  amount  of  expected  future  taxable 
income is not likely to support the use of the deduction or credit. Deferred tax liabilities are either (i) tax expenses recognized in 
the  consolidated  financial  statements  for  which  payment  has  been  deferred,  (ii)  expenses  for  which  we  have  already  taken  a 
deduction  on  the  tax  return  but  have  not  yet  recognized  in  the  consolidated  financial  statements  or  (iii)  liabilities  for  the 
difference between the book basis and the tax basis of the intangible assets acquired in many business combinations, because 
future expenses associated with these assets most often will not be tax deductible. 

We  are  a  vertically  integrated  enterprise  with  operations  in  the  United  States  and  various  foreign  jurisdictions.  In  the 
jurisdictions  where  we  conduct  operations,  we  are  subject  to  income  tax  based  on  the  tax  laws  and  principles  of  such 
jurisdictions and on the functions, risks and activities performed therein. Our pretax income is therefore attributed to domestic 
or foreign sources based on the operations performed and risks assumed in each location and the tax laws and principles of the 
respective taxing jurisdictions. For example, we conduct significant operations in Puerto Rico, a territory of the United States 
that  is  treated  as  a  foreign  jurisdiction  for  U.S.  tax  purposes,  pertaining  to  manufacturing,  distribution  and  other  related 
functions to meet our worldwide product demand. Income from our operations in Puerto Rico is subject to tax incentive grants 
through 2050.

In  2017,  we  received  an  RAR  and  a  modified  RAR  from  the  IRS  for  the  years  2010–2012,  proposing  significant 
adjustments  that  primarily  relate  to  the  allocation  of  profits  between  certain  of  our  entities  in  the  United  States  and  the  U.S. 
territory  of  Puerto  Rico.  We  disagreed  with  the  proposed  adjustments  and  calculations  and  pursued  resolution  with  the  IRS 
appeals  office  but  were  unable  to  reach  resolution.  In  July  2021,  we  filed  a  petition  in  the  U.S.  Tax  Court  to  contest  two 
duplicate Statutory Notices of Deficiency (Notices) for the years 2010–2012 that we received in May and July 2021, which seek 
to  increase  our  U.S.  taxable  income  for  the  years  2010–2012  by  an  amount  that  would  result  in  additional  federal  tax  of 
approximately $3.6 billion plus interest. Any additional tax that could be imposed for the years 2010–2012 would be reduced 
by up to approximately $900 million of repatriation tax previously accrued on our foreign earnings.

72

In  2020,  we  received  an  RAR  and  a  modified  RAR  from  the  IRS  for  the  years  2013–2015,  also  proposing  significant 
adjustments  that  primarily  relate  to  the  allocation  of  profits  between  certain  of  our  entities  in  the  United  States  and  the  U.S. 
territory of Puerto Rico similar to those proposed for the years 2010–2012. We disagreed with the proposed adjustments and 
calculations and pursued resolution with the IRS appeals office but were unable to reach resolution. In July 2022, we filed a 
petition in the U.S. Tax Court to contest a Notice for the years 2013–2015 that we received in April 2022 that seeks to increase 
our U.S. taxable income for the years 2013–2015 by an amount that would result in additional federal tax of approximately $5.1 
billion,  plus  interest.  In  addition,  the  Notice  asserts  penalties  of  approximately  $2.0  billion.  Any  additional  tax  that  could  be 
imposed for the years 2013–2015 would be reduced by up to approximately $2.2 billion of repatriation tax previously accrued 
on our foreign earnings.

We firmly believe that the IRS positions set forth in the 2010–2012 and 2013–2015 Notices are without merit. We are 
contesting the 2010–2012 and 2013–2015 Notices through the judicial process. The two cases were consolidated in U.S. Tax 
Court on December 19, 2022.

We  are  currently  under  examination  by  the  IRS  for  the  years  2016–2018  with  respect  to  issues  similar  to  those  for  the 

2010 through 2015 period. In addition, we have examinations by a number of state and foreign tax jurisdictions.

Final resolution of these complex matters is not likely within the next 12 months. We believe our accrual for income tax 
liabilities  is  appropriate  based  on  past  experience,  interpretations  of  tax  law,  application  of  the  tax  law  to  our  facts  and 
judgments  about  potential  actions  by  tax  authorities;  however,  due  to  the  complexity  of  the  provision  for  income  taxes  and 
uncertain resolution of these matters, the ultimate outcome of any tax matters may result in payments substantially greater than 
amounts accrued and could have a material adverse impact on our consolidated financial statements. See Part I, Item 1A. Risk 
Factors—The  adoption  and  interpretation  of  new  tax  legislation  or  exposure  to  additional  tax  liabilities  could  affect  our 
profitability;  Part  II,  Item  7.  Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations—
Results of Operations, Income taxes; and Part IV—Note 6, Income taxes, to the Consolidated Financial Statements for further 
discussion.

Our operations are subject to the tax laws, regulations and administrative practices of the United States, the U.S. territory 
of Puerto Rico, U.S. state jurisdictions and other countries in which we do business. Significant changes in these rules could 
have a material adverse effect on our results of operations. See Part I, Item 1A. Risk Factors—The adoption and interpretation 
of new tax legislation or exposure to additional tax liabilities could affect our profitability.

Contingencies

In  the  ordinary  course  of  business,  we  are  involved  in  various  legal  proceedings,  government  investigations  and  other 
matters such as intellectual property disputes, contractual disputes and class action suits that are complex in nature and have 
outcomes that are difficult to predict. We describe our legal proceedings and other matters that are significant or that we believe 
could become significant in Part IV—Note 19, Contingencies and commitments, to the Consolidated Financial Statements. We 
record  accruals  for  loss  contingencies  to  the  extent  that  we  conclude  it  is  probable  that  a  liability  has  been  incurred  and  the 
amount of the related loss can be reasonably estimated. We evaluate, on a quarterly basis, developments in legal proceedings 
and other matters that could cause an increase or decrease in the amount of the liability that has been accrued previously.

While it is not possible to accurately predict or determine the eventual outcomes of these items, an adverse determination 
in one or more of these items currently pending could have a material adverse effect on our consolidated results of operations, 
financial position or cash flows.

Valuation of assets and liabilities in connection with acquisitions

We  have  acquired  and  continue  to  acquire  intangible  assets  in  connection  with  business  combinations  and  asset 
acquisitions.  These  intangible  assets  consist  primarily  of  technology  associated  with  currently  marketed  human  therapeutic 
products and IPR&D product candidates. Discounted cash flow models are typically used to determine the fair values of these 
intangible assets for purposes of allocating consideration paid to the net assets acquired in an acquisition. See Part IV—Note 2, 
Acquisitions and divestitures, to the Consolidated Financial Statements. These models require the use of significant estimates 
and assumptions, including but not limited to:

•

•

•

determining the timing and expected costs to complete in-process projects, taking into account the stage of completion at 
the acquisition date;

projecting  the  probability  and  timing  of  obtaining  marketing  approval  from  the  FDA  and  other  regulatory  agencies  for 
product candidates;

estimating the timing of and future net cash flows from product sales resulting from completed products and in-process 
projects; and

73

•

developing appropriate discount rates to calculate the present values of the cash flows. 

Significant  estimates  and  assumptions  are  also  required  to  determine  the  business  combination  date  fair  values  of  any 
contingent  consideration  obligations  incurred  in  connection  with  business  combinations.  In  addition,  we  must  revalue  these 
obligations each subsequent reporting period until the related contingencies are resolved and record changes in their fair values 
in  earnings.  The  acquisition  date  fair  values  of  contingent  consideration  obligations  incurred  or  assumed  in  the  acquisitions 
were  determined  using  a  combination  of  valuation  techniques.  Significant  estimates  and  assumptions  required  for  these 
valuations  included  but  were  not  limited  to  the  timing  and  probability  of  achieving  regulatory  milestones,  product  sales 
projections  under  various  scenarios  and  discount  rates  used  to  calculate  the  present  value  of  the  required  payments.  These 
estimates  and  assumptions  are  required  to  be  updated  in  order  to  revalue  these  contingent  consideration  obligations  each 
reporting  period.  Accordingly,  subsequent  changes  in  underlying  facts  and  circumstances  could  result  in  changes  in  these 
estimates and assumptions, which could have a material impact on the estimated future fair values of these obligations.

We believe the fair values used to record intangible assets acquired and contingent consideration obligations incurred in 
connection with business combinations and asset acquisitions are based on reasonable estimates and assumptions given the facts 
and circumstances as of the related valuation dates.

Impairment of long-lived assets

We review the carrying value of our property, plant and equipment and our finite-lived intangible assets for impairment 
whenever  events  or  changes  in  circumstances  indicate  that  the  carrying  amount  of  an  asset  may  not  be  recoverable.  If  such 
circumstances exist, an estimate of undiscounted future cash flows to be generated by the long-lived asset is compared with the 
carrying value to determine whether an impairment exists. If an asset is determined to be impaired, the loss is measured based 
on the difference between the asset’s fair value and its carrying value.

Indefinite-lived intangible assets, composed of IPR&D projects acquired in a business combination that have not reached 
technological  feasibility  or  that  lack  regulatory  approval  at  the  time  of  acquisition,  are  reviewed  for  impairment  annually, 
whenever events or changes in circumstances indicate that the carrying amount may not be recoverable and upon establishment 
of  technological  feasibility  or  regulatory  approval.  We  determine  impairment  by  comparing  the  fair  value  of  the  asset  to  its 
carrying value. If the asset’s carrying value exceeds its fair value, an impairment charge is recorded for the difference, and its 
carrying value is reduced accordingly.

Estimating future cash flows of an IPR&D product candidate for purposes of an impairment analysis requires us to make 
significant estimates and assumptions regarding the amount and timing of costs to complete the project and the amount, timing 
and probability of achieving revenues from the completed product similar to how the acquisition date fair value of the project 
was determined, as described above. There are often major risks and uncertainties associated with IPR&D projects as we are 
required to obtain regulatory approvals in order to be able to market these products. Such approvals require completing clinical 
trials  that  demonstrate  a  product  candidate  is  safe  and  effective.  Consequently,  the  eventual  realized  value  of  the  acquired 
IPR&D  project  may  vary  from  its  fair  value  at  the  date  of  acquisition,  and  IPR&D  impairment  charges  may  occur  in  future 
periods which could have a material adverse effect on our results of operations.

We  believe  our  estimations  of  future  cash  flows  used  for  assessing  impairment  of  long-lived  assets  are  based  on 

reasonable assumptions given the facts and circumstances as of the related dates of the assessments.

Impairment of equity method investments

We  review  the  carrying  value  of  our  equity  method  investments  whenever  events  or  changes  in  circumstances  indicate 
that  the  carrying  amount  of  an  investment  may  not  be  recoverable.  We  record  impairment  losses  on  our  equity  method 
investments if we deem the impairment to be other-than-temporary. We deem an impairment to be other-than-temporary based 
on various factors, including but not limited to, the length of time and the extent to which the fair value is below the carrying 
value, volatility of the security price, the financial condition of the issuer, changes in technology that may impair the earnings 
potential of the investment and our intent and ability to retain the investment to allow for a recovery in fair value. 

We  believe  our  judgments  used  in  assessing  impairment  of  equity  method  investments  are  based  on  reasonable 

assumptions given the facts and circumstances as of the related dates of the assessments.

Item 7A.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risks that may result from changes in interest rates, foreign currency exchange rates and prices 
of equity instruments as well as changes in general economic conditions in the countries where we conduct business. To reduce 
certain of these risks, we enter into various types of foreign currency and interest rate derivative hedging transactions as part of 
our risk management program. We do not use derivatives for speculative trading purposes.

In  the  discussion  that  follows,  we  assumed  a  hypothetical  change  in  interest  rates  of  100  basis  points  from  those  as  of 
December  31,  2022  and  2021.  Except  as  noted  below,  we  also  assumed  a  hypothetical  20%  change  in  foreign  currency 
exchange rates against the U.S. dollar based on its position relative to other currencies as of December 31, 2022 and 2021.

Interest-rate-sensitive financial instruments

Our portfolio of available-for-sale investments as of December 31, 2022 and 2021, was composed almost entirely of U.S. 
Treasury securities and money market mutual funds. The fair values of our available-for-sale investments were $4.3 billion and 
$7.3 billion as of December 31, 2022 and 2021, respectively. Duration is a sensitivity measure that can be used to approximate 
the change in the value of a security that will result from a 100 basis point change in interest rates. Applying a duration model, a 
hypothetical 100 basis point increase in interest rates as of December 31, 2022 and 2021, would not have resulted in a material 
reduction  in  the  fair  values  of  these  securities.  In  addition,  a  hypothetical  100  basis  point  decrease  in  interest  rates  as  of 
December 31, 2022 and 2021, would not result in a material effect on income in the respective ensuing year.

As of December 31, 2022, we had outstanding debt with a carrying value of $38.9 billion and a fair value of $35.0 billion. 
As of December 31, 2021, we had outstanding debt with a carrying value of $33.3 billion and a fair value of $37.9 billion. Our 
outstanding  debt  was  composed  of  debt  with  fixed  interest  rates.  Changes  in  interest  rates  do  not  affect  interest  expense  on 
fixed-rate  debt.  Changes  in  interest  rates  would,  however,  affect  the  fair  values  of  fixed-rate  debt.  A  hypothetical  100  basis 
point decrease in interest rates relative to interest rates as of December 31, 2022 and 2021, would have resulted in an increase of 
$3.5 billion and $4.5 billion, respectively, in the aggregate fair value of our outstanding debt on these dates. Analysis of the 
debt does not consider the impact that hypothetical changes in interest rates would have on related interest rate swap contracts 
and cross-currency swap contracts, discussed below.

To achieve a desired mix of fixed-rate and floating-rate debt, we entered into interest rate swap contracts that qualified 
and were designated for accounting purposes as fair value hedges for certain of our fixed-rate debt. These interest rate swap 
contracts  effectively  converted  a  fixed-rate  interest  coupon  to  a  floating-rate  LIBOR-based  coupon  over  the  life  of  the 
respective  notes.  Interest  rate  swap  contracts  with  aggregate  notional  amounts  of  $6.7  billion  were  outstanding  as  of  both 
December 31, 2022 and 2021. A hypothetical 100 basis point increase in interest rates relative to interest rates as of December 
31,  2022  and  2021,  would  have  resulted  in  reductions  in  fair  values  of  approximately  $210  million  and  $330  million, 
respectively, on our interest rate swap contracts on these dates. Analysis of the interest rate swap contracts does not consider the 
impact that hypothetical changes in interest rates would have on the related fair values of debt that these interest-rate-sensitive 
instruments were designed to offset. 

In connection with the anticipated issuance of long-term fixed-rate debt, we occasionally enter into forward interest rate 
contracts,  which  are  designated  as  cash  flow  hedges,  in  order  to  hedge  the  variability  in  cash  flows  due  to  changes  in  the 
applicable  U.S.  Treasury  rate  between  the  time  we  enter  into  these  contracts  and  the  time  the  related  debt  is  issued.  As  of 
December  31,  2022,  we  had  forward  interest  rate  contracts  outstanding  with  an  aggregate  notional  amount  of  $700  million; 
there were no outstanding forward interest rate contracts as of December 31, 2021. A hypothetical 100 basis point decrease in 
interest rates relative to interest rates as of December 31, 2022 would have resulted in a reduction in fair value of approximately 
$60 million on our forward interest rate contracts on this date.

As  of  both  December  31,  2022  and  2021,  we  had  outstanding  cross-currency  swap  contracts  with  aggregate  notional 
amount  of  $3.4  billion  that  hedge  our  foreign-currency-denominated  debt  and  related  interest  payments.  These  contracts 
effectively convert interest payments and principal repayment of this debt to U.S. dollars from euros, pounds sterling and Swiss 
francs and are designated for accounting purposes as cash flow hedges. A hypothetical 100 basis point adverse movement in 
interest rates relative to interest rates as of December 31, 2022 and 2021, would have resulted in reductions in the fair values of 
our cross-currency swap contracts of approximately $90 million and $170 million, respectively.

75

Foreign-currency-sensitive financial instruments

Our international operations are affected by fluctuations in the value of the U.S. dollar compared with foreign currencies, 
predominantly  the  euro.  Increases  and  decreases  in  our  international  product  sales  from  movements  in  foreign  currency 
exchange  rates  are  partially  offset  by  corresponding  increases  or  decreases  in  our  international  operating  expenses.  Increases 
and  decreases  in  our  foreign-currency-denominated  assets  from  movements  in  foreign  currency  exchange  rates  are  partially 
offset  by  corresponding  increases  or  decreases  in  our  foreign-currency-denominated  liabilities.  To  further  reduce  our  net 
exposure to foreign currency exchange rate fluctuations on our results of operations, we enter into foreign currency forward and 
cross-currency swap contracts.

As of December 31, 2022, we had outstanding euro-, pound-sterling- and Swiss-franc-denominated debt with a principal 
carrying  value  and  a  fair  value  of  $3.0  billion  and  $2.9  billion,  respectively.  As  of  December  31,  2021,  we  had  outstanding 
euro-,  pound-sterling-  and  Swiss-franc-denominated  debt  with  a  principal  carrying  value  and  a  fair  value  of  $3.2  billion  and 
$3.6 billion, respectively. A hypothetical 20% adverse movement in foreign currency exchange rates compared with the U.S. 
dollar  relative  to  exchange  rates  as  of  December  31,  2022,  would  have  resulted  in  an  increase  in  fair  value  of  this  debt  of 
approximately  $580  million  on  this  date  and  a  reduction  in  income  in  the  ensuing  year  of  approximately  $600  million.  A 
hypothetical  20%  adverse  movement  in  foreign  currency  exchange  rates  compared  with  the  U.S.  dollar  relative  to  exchange 
rates as of December 31, 2021, would have resulted in an increase in fair value of this debt of $710 million on this date and a 
reduction  in  income  in  the  ensuing  year  of  $640  million.  The  impact  on  income  from  these  hypothetical  changes  in  foreign 
currency exchange rates would be substantially offset by the impact such changes would have on related cross-currency swap 
contracts, which are in place for the related foreign-currency-denominated debt.

We have cross-currency swap contracts that are designated as cash flow hedges of our debt denominated in euros, pounds 
sterling  and  Swiss  francs,  with  aggregate  notional  amount  of  $3.4  billion  as  of  both  December  31,  2022  and  2021.  A 
hypothetical  20%  adverse  movement  in  foreign  currency  exchange  rates  compared  with  the  U.S.  dollar  relative  to  exchange 
rates on these dates would have resulted in reductions in the fair values of these contracts of approximately $540 million and 
$700 million on these dates, respectively. The impact of this hypothetical adverse movement in foreign currency exchange rates 
on  ensuing  years’  income  from  these  contracts  would  be  fully  offset  by  corresponding  hypothetical  changes  in  the  carrying 
amounts of the related hedged debt.

We  enter  into  foreign  currency  forward  contracts  that  are  designated  for  accounting  purposes  as  cash  flow  hedges  of 
certain  anticipated  foreign  currency  transactions.  As  of  December  31,  2022,  the  fair  values  of  these  contracts  were  a  $288 
million asset and a $76 million liability. As of December 31, 2021, the fair values of these contracts were a $183 million asset 
and  a  $39  million  liability.  As  of  December  31,  2022,  we  had  primarily  euro-based  open  foreign  currency  forward  contracts 
with notional amounts of $6.0 billion. As of December 31, 2021, we had primarily euro-based open foreign currency forward 
contracts  with  notional  amounts  of  $5.7  billion.  With  regard  to  foreign  currency  forward  contracts  that  were  open  as  of 
December 31, 2022, a hypothetical 20% adverse movement in foreign currency exchange rates compared with the U.S. dollar 
relative  to  exchange  rates  as  of  December  31,  2022,  would  have  resulted  in  a  reduction  in  fair  value  of  these  contracts  of 
approximately  $1.1  billion  on  this  date  and  in  the  ensuing  year,  a  reduction  in  income  of  approximately  $590  million.  With 
regard  to  contracts  that  were  open  as  of  December  31,  2021,  a  hypothetical  20%  adverse  movement  in  foreign  currency 
exchange  rates  compared  with  the  U.S.  dollar  relative  to  exchange  rates  as  of  December  31,  2021,  would  have  resulted  in  a 
reduction  in  fair  value  of  these  contracts  of  approximately  $1.1  billion  on  this  date  and  in  the  ensuing  year,  a  reduction  in 
income of $390 million. The analysis does not consider the impact that hypothetical changes in foreign currency exchange rates 
would have on anticipated transactions that these foreign-currency-sensitive instruments were designed to offset.

As of December 31, 2022 and 2021, we had open, short-duration, foreign currency forward contracts that mature in one 
month or less, that had notional amounts of $0.5 billion and $0.7 billion, respectively, and that hedged fluctuations of certain 
assets  and  liabilities  denominated  in  foreign  currencies  but  were  not  designated  as  hedges  for  accounting  purposes.  These 
contracts  had  no  material  net  unrealized  gains  or  losses  as  of  December  31,  2022  and  2021.  With  regard  to  these  foreign 
currency forward contracts that were open as of December 31, 2022 and 2021, a hypothetical 5% adverse movement in foreign 
currency  exchange  rates  compared  with  the  U.S.  dollar  relative  to  exchange  rates  on  these  dates  would  not  have  a  material 
effect on the fair values of these contracts or related income in the respective ensuing years. The analysis does not consider the 
impact  that  hypothetical  changes  in  foreign  currency  exchange  rates  would  have  on  assets  and  liabilities  that  these  foreign-
currency-sensitive instruments were designed to offset.

Market-price-sensitive financial instruments

As  of  December  31,  2022  and  2021,  we  were  exposed  to  price  risk  on  equity  securities  included  in  our  portfolio  of 
investments, which were acquired primarily for the promotion of business and strategic objectives. These investments include 
publicly and privately held small-capitalization stocks, limited partnerships that invest in early-stage biotechnology companies 

76

and our investment in BeiGene. A 20% decrease in the aggregate value of our equity investment portfolio as of December 31, 
2022 and 2021, would result in losses in fair value of approximately $1.1 billion and $1.4 billion, respectively.

Counterparty credit risks

Our financial instruments, including derivatives, are subject to counterparty credit risk, which we consider as part of the 
overall  fair  value  measurement.  Our  financial  risk  management  policy  limits  derivative  transactions  by  requiring  that 
transactions be made only with institutions with minimum credit ratings of A– or equivalent by S&P, Moody’s or Fitch; and it 
places exposure limits on the amount with any individual counterparty. In addition, we have an investment policy that limits 
investments to certain types of debt and money market instruments issued by institutions with investment-grade credit ratings 
and places restriction on maturities and concentrations by asset class and issuer.

CONTROLS AND PROCEDURES

We  maintain  “disclosure  controls  and  procedures,”  as  such  term  is  defined  under  the  Securities  Exchange  Act 
Rule  13a-15(e),  that  are  designed  to  ensure  that  information  required  to  be  disclosed  in  Amgen’s  Exchange  Act  reports  is 
recorded,  processed,  summarized  and  reported  within  the  time  periods  specified  in  the  SEC’s  rules  and  forms  and  that  such 
information  is  accumulated  and  communicated  to  Amgen’s  management,  including  its  Chief  Executive  Officer  and  Chief 
Financial  Officer,  as  appropriate,  to  allow  timely  decisions  regarding  required  disclosures.  In  designing  and  evaluating  the 
disclosure  controls  and  procedures,  Amgen’s  management  recognized  that  any  controls  and  procedures,  no  matter  how  well 
designed  and  operated,  can  provide  only  reasonable  assurance  of  achieving  the  desired  control  objectives,  and  in  reaching  a 
reasonable  level  of  assurance,  Amgen’s  management  necessarily  was  required  to  apply  its  judgment  in  evaluating  the  cost-
benefit relationship of possible controls and procedures. We have carried out an evaluation under the supervision and with the 
participation of our management, including Amgen’s Chief Executive Officer and Chief Financial Officer, of the effectiveness 
of  the  design  and  operation  of  Amgen’s  disclosure  controls  and  procedures.  Based  upon  their  evaluation  and  subject  to  the 
foregoing, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were 
effective as of December 31, 2022.

Management  determined  that  as  of  December  31,  2022,  there  were  no  changes  in  our  internal  control  over  financial 
reporting that occurred during the fiscal quarter then ended that have materially affected or are reasonably likely to materially 
affect our internal control over financial reporting.

Management’s Report on Internal Control over Financial Reporting

Management  of  the  Company  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial 
reporting, as such term is defined in Rule 13a-15(f) under the Securities Exchange Act of 1934. The Company’s internal control 
over  financial  reporting  is  designed  to  provide  reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the 
preparation of financial statements for external purposes in accordance with GAAP in the United States. However, all internal 
control  systems,  no  matter  how  well  designed,  have  inherent  limitations.  Therefore,  even  those  systems  determined  to  be 
effective can provide only reasonable assurance with respect to financial statement preparation and reporting.

Management  assessed  the  effectiveness  of  the  Company’s  internal  control  over  financial  reporting  as  of  December  31, 
2022.  In  making  this  assessment,  management  used  the  criteria  set  forth  by  the  COSO  in  Internal  Control—Integrated 
Framework (2013 framework). Based on our assessment, management believes that the Company maintained effective internal 
control over financial reporting as of December 31, 2022, based on the COSO criteria.

The effectiveness of the Company’s internal control over financial reporting has been audited by Ernst & Young LLP, an 
independent  registered  public  accounting  firm,  as  stated  in  their  attestation  report  appearing  below,  which  expresses  an 
unqualified opinion on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2022.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Amgen Inc. 

Opinion on Internal Control Over Financial Reporting

We  have  audited  Amgen  Inc.’s  internal  control  over  financial  reporting  as  of  December  31,  2022,  based  on  criteria 
established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission  (2013  framework)  (the  COSO  criteria).  In  our  opinion,  Amgen  Inc.  (the  Company)  maintained,  in  all  material 
respects, effective internal control over financial reporting as of December 31, 2022, based on the COSO criteria.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United 
States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2022 and 2021, the related consolidated 
statements  of  income,  comprehensive  income,  stockholders’  equity  and  cash  flows  for  each  of  the  three  years  in  the  period 
ended December 31, 2022, and the related notes and the financial statement schedule listed in the Index at Item 15(a)2 and our 
report dated February 9, 2023 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its 
assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report 
on  Internal  Control  over  Financial  Reporting.  Our  responsibility  is  to  express  an  opinion  on  the  Company’s  internal  control 
over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be 
independent  with  respect  to  the  Company  in  accordance  with  the  U.S.  federal  securities  laws  and  the  applicable  rules  and 
regulations of the Securities and Exchange Commission and the PCAOB.

We  conducted  our  audit  in  accordance  with  the  standards  of  the  PCAOB.  Those  standards  require  that  we  plan  and 
perform  the  audit  to  obtain  reasonable  assurance  about  whether  effective  internal  control  over  financial  reporting  was 
maintained in all material respects.

Our  audit  included  obtaining  an  understanding  of  internal  control  over  financial  reporting,  assessing  the  risk  that  a 
material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed 
risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides 
a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted  accounting  principles.  A  company’s  internal  control  over  financial  reporting  includes  those  policies  and  procedures 
that  (1)  pertain  to  the  maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and 
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting  principles,  and  that  receipts  and 
expenditures  of  the  company  are  being  made  only  in  accordance  with  authorizations  of  management  and  directors  of  the 
company;  and  (3)  provide  reasonable  assurance  regarding  prevention  or  timely  detection  of  unauthorized  acquisition,  use,  or 
disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections  of  any  evaluation  of  effectiveness  to  future  periods  are  subject  to  the  risk  that  controls  may  become  inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

(1) The Amended 2009 Plan employs a fungible share-counting formula for determining the number of shares available for 
issuance  under  the  plan.  In  accordance  with  this  formula,  each  option  or  stock  appreciation  right  counts  as  one  share, 
while each RSU, performance unit or dividend equivalent counts as 1.9 shares. The number under column (a) represents 
the actual number of shares issuable under our outstanding awards without giving effect to the fungible share-counting 
formula. The number under column (c) represents the number of shares available for issuance under this plan based on 
each such available share counting as one share. Commencing with the grants made in April 2012, RSUs and performance 
units  accrue  dividend  equivalents  that  are  payable  in  shares  only  to  the  extent  and  when  the  underlying  RSUs  vest  or 
underlying  performance  units  have  been  earned  and  the  related  shares  are  issued  to  the  grantee.  The  performance  units 
granted  under  this  plan  are  earned  based  on  the  accomplishment  of  specified  performance  goals  at  the  end  of  their 
respective three-year performance periods; the number of performance units granted represent target performance, and the 
maximum number of units that could be earned based on our performance is 200% of the performance units granted in 
2020, 2021 and 2022. 

As of December 31, 2022, the number of outstanding awards under column (a) includes (i) 5,322,407 shares issuable upon 
the exercise of outstanding options with a weighted-average exercise price of $207.29; (ii) 3,173,806 shares issuable upon 
the  vesting  of  outstanding  RSUs  (including  307,825  related  dividend  equivalents);  and  (iii)  1,739,407  shares  subject  to 
outstanding  2020,  2021  and  2022  performance  units  (including  84,603  related  dividend  equivalents).  The  weighted-
average  exercise  price  shown  in  column  (b)  is  for  the  outstanding  options  only.  The  number  of  available  shares  under 
column (c) represents the number of shares that remain available for future issuance under this plan as of December 31, 
2022,  employing  the  fungible  share  formula  and  presumes  the  issuance  of  target  shares  under  the  performance  units 
granted  in  2020,  2021  and  2022  and  related  dividend  equivalents.  The  numbers  under  columns  (a)  and  (c)  do  not  give 
effect to the additional shares that could be issuable in the event above target performance on the performance goals under 
these outstanding performance units is achieved. Maximum performance under these goals could result in 200% of target 
shares being awarded for performance units granted in 2020, 2021 and 2022.

(2) This plan has terminated as to future grants. The number under column (a) with respect to this plan includes 2,191 shares 

issuable upon the settlement of deferred RSUs (including 519 related dividend equivalents).

(3) The  Profit  Sharing  Plan  was  approved  by  the  Board  of  Directors  on  July  28,  2011.  The  Profit  Sharing  Plan  permits 
eligible employees of the Company’s subsidiaries located in Ireland who participate in the Profit Sharing Plan to apply a 
portion of their qualifying bonus and salary to the purchase of the Company’s common stock on the open market at the 
market price by a third-party trustee as described in the Profit Sharing Plan.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Amgen Inc.

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheets of Amgen Inc. (the Company) as of December 31, 2022 and 
2021, the related consolidated statements of income, comprehensive income, stockholders’ equity and cash flows for each of 
the three years in the period ended December 31, 2022, and the related notes and the financial statement schedule listed in the 
Index  at  Item  15(a)2  (collectively  referred  to  as  the  “consolidated  financial  statements”).  In  our  opinion,  the  consolidated 
financial  statements  present  fairly,  in  all  material  respects,  the  financial  position  of  the  Company  at  December  31,  2022  and 
2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in 
conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company’s internal control over financial reporting as of December 31, 2022, based on criteria established in 
Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission 
(2013 framework) and our report dated February 9, 2023 expressed an unqualified opinion thereon.

Basis for Opinion 

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on 
the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission and the PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to 
error  or  fraud.  Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial 
statements,  whether  due  to  error  or  fraud,  and  performing  procedures  that  respond  to  those  risks.  Such  procedures  included 
examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included 
evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as  evaluating  the  overall 
presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that 
were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that 
are  material  to  the  financial  statements  and  (2)  involved  our  especially  challenging,  subjective  or  complex  judgments.  The 
communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as 
a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit 
matters or on the accounts or disclosures to which they relate.

Description of the 
Matter

How We 
Addressed the 
Matter in Our 
Audit

Sales deductions
As  of  December  31,  2022,  the  Company  recorded  accrued  sales  deductions  of  $6.0  billion.  As 
described in Note 1 to the financial statements under the caption “Product sales and sales deductions,” 
revenues  from  product  sales  are  recognized  net  of  accruals  for  estimated  rebates,  wholesaler 
chargebacks,  discounts  and  other  deductions  (collectively  sales  deductions),  which  are  established  at 
the time of sale.

Auditing  the  estimation  of  sales  deductions,  which  are  netted  against  product  sales,  is  complex, 
requires significant judgment, and the amounts involved are material to the financial statements taken 
as  a  whole.  Revenue  from  product  sales  is  recognized  upon  transfer  of  control  of  a  product  to  a 
customer, generally upon delivery, and is based on an amount that reflects the consideration to which 
the Company expects to be entitled, which represents an amount that is net of accruals for estimated 
sales  deductions.  The  estimated  sales  deductions  are  based  on  current  contractual  and  statutory 
requirements, market events and trends, internal and external historical data, and forecasted customer 
buying patterns.

We obtained an understanding, evaluated the design and tested the operating effectiveness of internal 
controls over the sales deduction processes. This included testing controls over management’s review 
of significant assumptions and inputs used in the estimate of sales deductions, including actual sales, 
contractual  terms,  historical  experience,  wholesaler  inventory  levels,  demand  data  and  estimated 
patient  population.  We  also  tested  management’s  controls  over  the  accuracy  of  forecasting  demand 
activity as well as the completeness and accuracy of the significant components included in the final 
sales deduction estimates. 

To  test  management’s  estimated  sales  deductions,  we  obtained  management’s  calculations  for  the 
respective estimates and performed the following procedures, among others. We tested management’s 
estimation  process  over  the  determination  of  sales  discount  accruals  by  developing  an  independent 
expectation  of  the  estimated  accrual  balances,  including  comparing  accrual  balances  recorded  by 
management  to  those  implied  by  historical  payment  trends,  performing  a  lookback  analysis  using 
actual  historical  data  to  evaluate  the  forecasted  amounts,  assessing  subsequent  events  to  determine 
whether there was any new information that would require adjustment to the initial accruals, evaluating 
trends  in  actual  sales  and  discount  accrual  balances,  comparing  cash  receipts  to  product  sales, 
confirming  terms  and  conditions  for  a  sample  of  contracts,  testing  a  sample  of  credits  issued  and 
payments made throughout the year, and agreeing rates to underlying contract terms.

Description of the 
Matter

Unrecognized tax benefits

As  discussed  in  Notes  1  and  6  to  the  consolidated  financial  statements,  the  Company  operates  in 
various  jurisdictions  in  which  differing  interpretations  of  complex  tax  laws  and  regulations  create 
uncertainty  and  necessitate  the  use  of  significant  judgment  in  the  determination  of  the  Company’s 
unrecognized  tax  benefits  related  to  allocation  of  profits  among  various  jurisdictions  (“transfer 
pricing”), particularly in the U.S. federal tax jurisdiction where the Company has significant assets and 
operations.  In  this  regard,  the  Company  uses  significant  judgment  in  (1)  determining  whether  a  tax 
position’s  technical  merits  are  more-likely-than-not  to  be  sustained  and  (2)  measuring  the  amount  of 
tax benefit that qualifies for recognition. As of December 31, 2022, the Company accrued $3.8 billion 
of gross unrecognized tax benefits including those related to transfer pricing. Auditing the assessment 
of  the  technical  merits  and  measurement  of  the  Company’s  unrecognized  tax  benefits  is  challenging 
and can be complex, highly judgmental, and based on interpretations of tax laws and regulations and 
application of those interpretations to the Company’s facts and circumstances.

How We 
Addressed the 
Matter in Our 
Audit

We obtained an understanding, evaluated the design and tested the operating effectiveness of internal 
controls  over  the  Company’s  process  to  assess  the  technical  merits  of  its  tax  positions,  as  well  as 
management’s process to measure the unrecognized tax benefits of those tax positions, particularly in 
regard  to  transfer  pricing.  This  included  testing  controls  over  management’s  review  of  the  inputs, 
calculations, assumptions and methods selected to measure the amount of tax benefits that qualify for 
recognition. 

We  involved  tax  and  transfer  pricing  specialists  to  assist  in  assessing  the  technical  merits  and 
measurement of certain of the Company’s unrecognized tax benefits. Depending on the nature of the 
specific tax position and, as applicable, developments with the relevant tax authorities, our procedures 
included  obtaining  and  reviewing  the  Company’s  correspondence  with  such  tax  authorities  and 
evaluating certain third-party advice to support the Company’s evaluations and recorded positions. We 
used our knowledge of and experience with how the income tax laws and regulations related to transfer 
pricing  are  applied  by  the  relevant  tax  authorities  to  evaluate  the  Company’s  accounting  for  its 
unrecognized  tax  benefits.  We  evaluated  developments  in  the  applicable  regulatory  environments  to 
assess  potential  effects  on 
the  Company’s  recorded  positions.  We  assessed  management’s 
consideration  of  current  tax  controversy,  litigation  and  tax  litigation  trends.  We  analyzed  the 
assumptions  and  data  used  by  the  Company  when  it  determined  the  amount  of  tax  benefits  to 
recognize, including applicable interest and penalties, and we tested the accuracy of those underlying 
calculations.  We  have  also  evaluated  the  Company’s  income  tax  disclosures  included  in  Note  6  in 
relation to these matters.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2022 

1. Summary of significant accounting policies

Business

Amgen  Inc.  (including  its  subsidiaries,  referred  to  as  “Amgen,”  “the  Company,”  “we,”  “our”  or  “us”)  is  a  global 
biotechnology pioneer that discovers, develops, manufactures and delivers innovative human therapeutics. We operate in one 
business segment: human therapeutics.

Principles of consolidation

The  consolidated  financial  statements  include  the  accounts  of  Amgen  as  well  as  its  majority-owned  subsidiaries.  In 
determining whether we are the primary beneficiary of a variable interest entity, we consider whether we have both the power 
to direct activities of the entity that most significantly impact the entity’s economic performance and the obligation to absorb 
losses of, or the right to receive benefits from, the entity that could potentially be significant to that entity. We do not have any 
significant  interests  in  any  variable  interest  entities  of  which  we  are  the  primary  beneficiary.  All  material  intercompany 
transactions and balances have been eliminated in consolidation.

Use of estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates 
and  assumptions  that  affect  the  amounts  reported  in  the  consolidated  financial  statements  and  accompanying  notes.  Actual 
results may differ from those estimates.

Revenues

Product sales and sales deductions

Revenue from product sales is recognized upon transfer of control of a product to a customer, generally upon delivery, 
based  on  an  amount  that  reflects  the  consideration  to  which  we  expect  to  be  entitled,  net  of  accruals  for  estimated  rebates, 
wholesaler chargebacks, discounts and other deductions (collectively, sales deductions) and returns established at the time of 
sale.

We  analyze  the  adequacy  of  our  accruals  for  sales  deductions  quarterly.  Amounts  accrued  for  sales  deductions  are 
adjusted when trends or significant events indicate that an adjustment is appropriate. Accruals are also adjusted to reflect actual 
results. Accruals for sales deductions are based primarily on estimates of the amounts earned or to be claimed on the related 
sales. These estimates take into consideration current contractual and statutory requirements, specific known market events and 
trends, internal and external historical data and forecasted customer buying patterns. Sales deductions are substantially product 
specific  and  therefore,  for  any  given  period,  can  be  affected  by  the  mix  of  products  sold.  Included  in  sales  deductions  are 
immaterial net adjustments related to prior-period sales due to changes in estimates.

Returns  are  estimated  through  comparison  of  historical  return  data  with  their  related  sales  on  a  production  lot  basis. 
Historical rates of return are determined for each product and are adjusted for known or expected changes in the marketplace 
specific to each product, when appropriate. Historically, sales return provisions have amounted to less than 1% of gross product 
sales. Changes in estimates for prior-period sales return provisions have historically been immaterial.

Our payment terms vary by types and locations of customers and by products or services offered. Payment terms differ by 
jurisdiction and customer, but payment is generally required in a term ranging from 30 to 120 days from date of shipment or 
satisfaction of the performance obligation. For certain products or services and certain customer types, we may require payment 
before products are delivered or services are rendered to customers.

Indirect taxes collected from customers and remitted to government authorities that are related to sales of the Company’s 

products, primarily in Europe, are excluded from revenues.

As a practical expedient, sales commissions are expensed when incurred because the amortization period would have been 

one year or less. These costs are recorded in SG&A expense in the Consolidated Statements of Income.

F-9

Other revenues

Other revenues consist primarily of royalty income and corporate partner revenues. Royalties from licensees are based on 
third-party  sales  of  licensed  products  and  are  recorded  when  the  related  third-party  product  sale  occurs.  Royalty  income  is 
estimated based on historical and forecasted sales trends. Corporate partner revenues are composed mainly of license fees and 
milestones  earned  and  our  share  of  commercial  profits  generated  from  collaborations.  See  Arrangements  with  multiple-
performance obligations, discussed below.

Arrangements with multiple-performance obligations

From  time  to  time,  we  enter  into  arrangements  for  the  R&D,  manufacture  and/or  commercialization  of  products  and 
product  candidates.  Such  arrangements  may  require  us  to  deliver  various  rights,  services  and/or  goods,  including  intellectual 
property  rights/licenses,  R&D  services,  manufacturing  services  and/or  commercialization  services.  The  underlying  terms  of 
these  arrangements  generally  provide  for  consideration  to  Amgen  in  the  form  of  nonrefundable,  upfront  license  fees; 
development and commercial-performance milestone payments; royalty payments; and/or profit sharing.

In  arrangements  involving  more  than  one  performance  obligation,  each  required  performance  obligation  is  evaluated  to 
determine whether it qualifies as a distinct performance obligation based on whether (i) the customer can benefit from the good 
or service either on its own or together with other resources that are readily available and (ii) the good or service is separately 
identifiable  from  other  promises  in  the  contract.  The  consideration  under  the  arrangement  is  then  allocated  to  each  separate 
distinct  performance  obligation  based  on  its  respective  relative  stand-alone  selling  price.  The  estimated  selling  price  of  each 
deliverable reflects our best estimate of what the selling price would be if the deliverable was regularly sold by us on a stand-
alone basis or by using an adjusted market assessment approach if selling price on a stand-alone basis is not available.

The consideration allocated to each distinct performance obligation is recognized as revenue when control of the related 
goods  or  services  is  transferred.  Consideration  associated  with  at-risk  substantive  performance  milestones  is  recognized  as 
revenue when it is probable that a significant reversal of the cumulative revenue recognized will not occur. We utilize the sales- 
and usage-based royalty exception in arrangements that resulted from the license of intellectual property, recognizing revenues 
generated from royalties or profit sharing as the underlying sales occur.

Research and development costs

R&D  costs  are  expensed  as  incurred  and  primarily  include  salaries,  benefits  and  other  staff-related  costs;  facilities  and 
overhead  costs;  clinical  trial  and  related  clinical  manufacturing  costs;  contract  services  and  other  outside  costs;  information 
systems’ costs; and amortization of acquired technology used in R&D with alternative future uses. R&D expenses also include 
costs  and  cost  recoveries  associated  with  third-party  R&D  arrangements,  including  upfront  fees  and  milestones  paid  to  third 
parties in connection with technologies that had not reached technological feasibility and did not have an alternative future use. 
Net payment or reimbursement of R&D costs is recognized when the obligations are incurred or as we become entitled to the 
cost recovery. See Note 8, Collaborations.

Selling, general and administrative costs

SG&A costs are primarily composed of salaries, benefits and other staff-related costs associated with sales and marketing, 
finance,  legal  and  other  administrative  personnel;  facilities  and  overhead  costs;  outside  marketing,  advertising  and  legal 
expenses; the U.S. healthcare reform federal excise fee on Branded Prescription Pharmaceutical Manufacturers and Importers; 
and other general and administrative costs. Advertising costs are expensed as incurred and were $841 million, $843 million and 
$962 million during the years ended December 31, 2022, 2021 and 2020, respectively. SG&A expenses also include costs and 
cost  recoveries  associated  with  marketing  and  promotion  efforts  under  certain  collaborative  arrangements.  Net  payment  or 
reimbursement of SG&A costs is recognized when the obligations are incurred or we become entitled to the cost recovery. See 
Note 8, Collaborations.

Leases

At inception of a contract, we determine whether an arrangement is or contains a lease. For all leases, we determine the 
classification as either operating or financing. Operating leases are included in Other noncurrent assets, Accrued liabilities and 
Other noncurrent liabilities in our Consolidated Balance Sheets.

F-10

ROU assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our obligation 
to make lease payments under the lease. Lease recognition occurs at the commencement date, and lease liability amounts are 
based  on  the  present  value  of  lease  payments  made  during  the  lease  term.  Our  lease  terms  may  include  options  to  extend  or 
terminate  a  lease  when  it  is  reasonably  certain  that  we  will  exercise  that  option.  Because  most  of  our  leases  do  not  provide 
information to determine an implicit interest rate, we use our incremental borrowing rate in determining the present value of 
lease  payments.  ROU  assets  also  include  any  lease  payments  made  prior  to  the  commencement  date  less  lease  incentives 
received. Operating lease expense is recognized on a straight-line basis over the lease term.

We  have  lease  agreements  with  both  lease  and  nonlease  components,  which  are  generally  accounted  for  together  as  a 
single lease component. In addition, for certain vehicle and equipment leases, we apply a portfolio approach to determine the 
lease term and discount rate.

Stock-based compensation

We have stock-based compensation plans under which various types of equity-based awards are granted, including RSUs, 
performance  units  and  stock  options.  The  fair  values  of  RSUs  and  stock  option  awards,  which  are  subject  only  to  service 
conditions  with  graded  vesting,  are  recognized  as  compensation  expense,  generally  on  a  straight-line  basis  over  the  service 
period,  net  of  estimated  forfeitures.  The  fair  values  of  performance  unit  awards  are  recognized  as  compensation  expense, 
generally  on  a  straight-line  basis  from  the  grant  date  to  the  end  of  the  performance  period.  See  Note  4,  Stock-based 
compensation.

Income taxes

We  provide  for  income  taxes  based  on  pretax  income  and  applicable  tax  rates  in  the  various  jurisdictions  in  which  we 
operate. Significant judgment is required in determining our provision for income taxes and income tax assets and liabilities, 
including evaluating uncertainties in the application of accounting principles and complex tax laws. Deferred income taxes are 
recorded for the expected tax consequences of temporary differences between the bases of assets and liabilities, as well as for 
loss and tax credit carryforwards for financial reporting purposes and amounts recognized for income tax purposes. We record a 
valuation  allowance  to  reduce  our  deferred  tax  assets  to  the  amount  of  future  tax  benefit  that  is  more  likely  than  not  to  be 
realized.

We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be 
sustained upon examination by tax authorities based on the technical merits of the position. The tax benefit recognized in the 
consolidated financial statements for a particular tax position is based on the largest benefit that is more likely than not to be 
realized.  The  amount  of  UTBs  is  adjusted  as  appropriate  for  changes  in  facts  and  circumstances,  such  as  significant 
amendments to existing tax law, new regulations or interpretations by tax authorities, new information obtained during a tax 
examination  or  resolution  of  an  examination.  We  recognize  both  accrued  interest  and  penalties,  when  appropriate,  related  to 
UTBs in income tax expense. See Note 6, Income taxes. 

Acquisitions

We  first  determine  whether  a  set  of  assets  acquired  constitute  a  business  and  should  be  accounted  for  as  a  business 
combination. If the assets acquired do not constitute a business, we account for the transaction as an asset acquisition. Business 
combinations  are  accounted  for  by  means  of  the  acquisition  method  of  accounting.  Under  the  acquisition  method,  assets 
acquired, including IPR&D projects, and liabilities assumed are recorded at their respective fair values as of the acquisition date 
in our consolidated financial statements. The excess of the fair value of consideration transferred over the fair value of the net 
assets  acquired  is  recorded  as  goodwill.  Contingent  consideration  obligations  incurred  in  connection  with  a  business 
combination  (including  the  assumption  of  an  acquiree’s  liability  arising  from  an  acquisition  it  consummated  prior  to  our 
acquisition)  are  recorded  at  their  fair  values  on  the  acquisition  date  and  remeasured  at  their  fair  values  each  subsequent 
reporting  period  until  the  related  contingencies  have  been  resolved.  The  resulting  changes  in  fair  values  are  recorded  in 
earnings. In contrast, asset acquisitions are accounted for by using a cost accumulation and allocation model. Under this model, 
the cost of the acquisition is allocated to the assets acquired and liabilities assumed. IPR&D projects with no alternative future 
use  are  recorded  in  R&D  expense  upon  acquisition,  and  contingent  consideration  obligations  incurred  in  connection  with  an 
asset  acquisition  are  recorded  when  it  is  probable  that  they  will  occur  and  they  can  be  reasonably  estimated.  See  Note  2, 
Acquisitions and divestitures, and Note 17, Fair value measurement.

Cash equivalents

We consider cash equivalents to be only those investments that are highly liquid, that are readily convertible to cash and 

that mature within three months from the date of purchase.

F-11

Interest-bearing securities

We consider our interest-bearing securities investment portfolio as available-for-sale, and accordingly, these investments 
are recorded at fair value, with unrealized gains and losses recorded in AOCI. Investments with maturities beyond one year may 
be  classified  as  short-term  marketable  securities  in  the  Consolidated  Balance  Sheets  due  to  their  highly  liquid  nature  and 
because they represent the Company’s investments that are available for current operations. See Note 9, Investments, and Note 
17, Fair value measurement.

Inventories

Inventories are stated at the lower of cost or net realizable value. Cost, which includes amounts related to materials, labor 
and overhead, is determined in a manner that approximates the first-in, first-out method. Net realizable value is the estimated 
selling price in the ordinary course of business less reasonably predictable costs of completion, disposal and transportation. See 
Note 10, Inventories.

Derivatives

We  recognize  all  of  our  derivative  instruments  as  either  assets  or  liabilities  at  fair  value  in  the  Consolidated  Balance 
Sheets.  The  accounting  for  changes  in  the  fair  value  of  a  derivative  instrument  depends  on  whether  the  derivative  has  been 
formally designated and qualifies as part of a hedging relationship under the applicable accounting standards and, further, on 
the  type  of  hedging  relationship.  For  derivatives  formally  designated  as  hedges,  we  assess  both  at  inception  and  quarterly 
thereafter whether the hedging derivatives are highly effective in offsetting changes in either the fair value or cash flows of the 
hedged  item.  Our  derivatives  that  are  not  designated  and  do  not  qualify  as  hedges  are  adjusted  to  fair  value  through  current 
earnings. See Note 17, Fair value measurement, and Note 18, Derivative instruments.

Property, plant and equipment, net

Property,  plant  and  equipment  is  recorded  at  historical  cost,  net  of  accumulated  depreciation,  amortization  and,  if 
applicable,  impairment  charges.  We  review  our  property,  plant  and  equipment  assets  for  impairment  whenever  events  or 
changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Depreciation is recorded over 
the assets’ useful lives on a straight-line basis. Leasehold improvements are amortized on a straight-line basis over the shorter 
of their estimated useful lives or lease terms. See Note 11, Property, plant and equipment.

Goodwill and other intangible assets

Finite-lived intangible assets are recorded at cost, net of accumulated amortization, and, if applicable, impairment charges. 
Amortization of finite-lived intangible assets is recorded over the assets’ estimated useful lives on a straight-line basis or based 
on the pattern in which economic benefits are consumed, if reliably determinable. We review our finite-lived intangible assets 
for  impairment  whenever  events  or  changes  in  circumstances  indicate  that  the  carrying  amount  of  an  asset  may  not  be 
recoverable. See Note 12, Goodwill and other intangible assets.

The fair values of IPR&D projects acquired in a business combination that are not complete are capitalized and accounted 
for  as  indefinite-lived  intangible  assets  until  completion  or  abandonment  of  the  related  R&D  efforts.  Upon  successful 
completion  of  the  project,  the  capitalized  amount  is  amortized  over  its  estimated  useful  life.  If  a  project  is  abandoned,  all 
remaining  capitalized  amounts  are  written  off  immediately.  Major  risks  and  uncertainties  are  often  associated  with  IPR&D 
projects because we are required to obtain regulatory approvals before marketing the resulting products. Such approvals require 
completing clinical trials that demonstrate a product candidate is safe and effective. Consequently, the eventual realized value 
of  the  acquired  IPR&D  project  may  vary  from  its  fair  value  at  the  date  of  acquisition,  and  IPR&D  impairment  charges  may 
occur in future periods.

Capitalized IPR&D projects are tested for impairment annually and whenever events or changes in circumstances indicate 
that the carrying amount may not be recoverable. We consider various factors for potential impairment, including the current 
legal and regulatory environment and the competitive landscape. Adverse clinical trial results, significant delays in obtaining 
marketing  approval,  the  inability  to  bring  a  product  to  market  and  the  introduction  or  advancement  of  competitors’  products 
could result in partial or full impairment of the related intangible assets.

We perform an impairment test of goodwill annually and whenever events or changes in circumstances indicate that the 
carrying amount may not be recoverable. To date, an impairment of goodwill has not been recorded. See Note 12, Goodwill and 
other intangible assets.

F-12

Contingencies

In  the  ordinary  course  of  business,  we  are  involved  in  various  legal  proceedings,  government  investigations  and  other 
matters that are complex in nature and have outcomes that are difficult to predict. Certain of these proceedings are discussed in 
Note  19,  Contingencies  and  commitments.  We  record  accruals  for  loss  contingencies  to  the  extent  that  we  conclude  it  is 
probable that a liability has been incurred and the amount of the related loss can be reasonably estimated. We evaluate, on a 
quarterly basis, developments in legal proceedings and other matters that could cause an increase or decrease in the amount of 
the liability that has been accrued previously.

Foreign currency translation

The  net  assets  of  international  subsidiaries  whose  functional  currencies  are  not  in  U.S.  dollars  are  translated  into  U.S. 
dollars using current exchange rates. The U.S. dollar effects that arise from translation of the net assets of these subsidiaries at 
changing rates are recognized in AOCI. The subsidiaries’ earnings are translated into U.S. dollars by using average exchange 
rates.

Equity investments

Marketable and nonmarketable equity securities

Investments in publicly traded equity securities with readily determinable fair values are recorded at quoted market prices 
for identical securities, with changes in fair value recorded in Other (expense) income, net, in the Consolidated Statements of 
Income. Investments in equity securities without readily determinable fair values are recorded at cost minus impairment, if any, 
adjusted  for  changes  resulting  from  observable  price  changes  in  orderly  transactions  for  identical  or  similar  securities.  Such 
adjustments are recorded in Other (expense) income, net, in the Consolidated Statements of Income.

Equity method investments

Equity investments that give us the ability to exert significant influence, but not control, over an investee for which we 
have not elected the fair value option are accounted for under the equity method of accounting. In concluding whether we have 
the ability to exercise significant influence over an investee, we consider factors such as our ownership percentage, voting and 
other shareholder rights, board of directors representation and the existence of other collaborative or business relationships. The 
equity  method  of  accounting  requires  us  to  allocate  the  difference  between  the  fair  value  of  securities  acquired  and  our 
proportionate  share  of  the  carrying  value  of  the  underlying  assets  (the  basis  difference)  to  various  items  and  amortize  such 
differences over their useful lives. Our share of investees’ earnings or losses and amortization of basis differences, if any, are 
recorded  one  quarter  in  arrears  in  Other  (expense)  income,  net,  in  the  Consolidated  Statements  of  Income.  We  record 
impairment  losses  on  our  equity  method  investments  if  we  deem  the  impairment  to  be  other-than-temporary.  We  deem  an 
impairment to be other-than-temporary based on various factors, including but not limited to, the length of time the fair value is 
below  the  carrying  value,  volatility  of  the  security  price  and  our  intent  and  ability  to  retain  the  investment  to  allow  for  a 
recovery in fair value.

For equity method investments for which we have elected the fair value option, changes in fair value are recorded in Other 

(expense) income, net, in the Consolidated Statements of Income.

Additionally, we hold investments in limited partnerships, which primarily invest in early-stage biotechnology companies. 
As a practical expedient, such limited partnership investments are measured by using our proportionate share of the net asset 
values of the underlying investments held by the limited partnerships, with such changes included in Other (expense) income, 
net, in the Consolidated Statements of Income.

Recent accounting pronouncements

In  March  2020,  the  FASB  issued  a  new  accounting  standard  to  ease  the  financial  reporting  burdens  caused  by  the 
expected market transition from the LIBOR and other interbank offered rates to alternative reference rates, commonly referred 
to  as  reference  rate  reform.  The  new  standard  provides  temporary  optional  expedients  and  exceptions  to  current  GAAP 
guidance on contract modifications and hedge accounting. Specifically, a modification to transition to an alternative reference 
rate  is  treated  as  an  event  that  does  not  require  contract  remeasurement  or  reassessment  of  a  previous  accounting  treatment. 
Moreover,  for  all  types  of  hedging  relationships,  an  entity  is  permitted  to  change  the  reference  rate  without  having  to 
dedesignate the hedging relationship. In January 2021, the FASB issued a new accounting standard to expand the scope of the 
original March 2020 standard to include derivative instruments on discounting transactions. The provisions of these standards 
have not had and are not expected to have a material impact on our consolidated financial statements.

F-13

In  November  2021,  the  FASB  issued  a  new  accounting  standard  around  the  recognition  and  measurement  of  contract 
assets  and  contract  liabilities  from  revenue  contracts  with  customers  acquired  in  a  business  combination.  The  new  standard 
clarifies  that  contract  assets  and  contract  liabilities  acquired  in  a  business  combination  from  an  acquiree  should  initially  be 
recognized by applying revenue recognition principles and not at fair value. The standard is effective for interim and annual 
periods beginning on January 1, 2023, and early adoption is permitted. The impact of this standard will depend on the facts and 
circumstances of future transactions.

 2. Acquisitions and divestitures 

Proposed acquisition of Horizon Therapeutics plc

On December 12, 2022, we announced that we entered into a transaction agreement under which Amgen will acquire all 
shares  of  Horizon  for  $116.50  per  share  in  cash  for  a  transaction  equity  value  of  approximately  $27.8  billion.  Horizon  is  a 
global  biotechnology  company  headquartered  in  Dublin,  Ireland  and  is  focused  on  the  discovery,  development  and 
commercialization of medicines that address critical needs for people impacted by rare, autoimmune and severe inflammatory 
diseases.  Horizon  has  12  marketed  medicines  and  a  pipeline  with  more  than  20  development  programs.  The  closing  of  this 
transaction is contingent upon satisfaction of certain regulatory (including FTC review) and other customary closing conditions.

In  connection  with  the  proposed  acquisition  of  Horizon,  Amgen  entered  into  a  364-day  bridge  credit  agreement  with  a 
syndicated group of banks for an aggregate amount of $28.5 billion on December 12, 2022. On December 22, 2022, we entered 
into  a  term  loan  credit  agreement  with  an  aggregate  principal  amount  of  $4.0  billion  which  provides  for  two  equally  sized 
tranches of term loans, one with an 18-month term and one with a three-year term. Accordingly, the bridge credit agreement 
was reduced by the amount of the term loan credit agreement to $24.5 billion. As of December 31, 2022, no amounts have been 
drawn under the bridge credit agreement or the term loan credit agreement. In connection with these credit agreements, Amgen 
incurred  approximately  $97  million  of  financing  costs,  which  was  capitalized  primarily  in  Other  current  assets  in  our 
Consolidated Balance Sheets and is being amortized to Interest expense, net, in our Consolidated Statements of Income over the 
terms  of  the  agreements.  Additionally,  we  have  agreed  to  maintain  a  cash  balance  of  $2.96  billion  that,  together  with  any 
borrowings under the bridge credit agreement and term loan credit agreement, represents sources of funds available to finance 
the acquisition.

On  January  30,  2023,  the  Company  and  Horizon  each  received  a  request  for  additional  information  and  documentary 
materials  (Second  Request)  from  the  FTC  in  connection  with  the  FTC’s  review  of  the  Company’s  proposed  acquisition  of 
Horizon.  The  effect  of  the  Second  Request  is  to  extend  the  waiting  period  imposed  by  the  Hart-Scott-Rodino  Antitrust 
Improvements  Act  of  1976,  as  amended,  until  30  days  after  the  Company  and  Horizon  have  substantially  complied  with  the 
Second Request, unless that period is extended voluntarily by the Company and Horizon or terminated sooner by the FTC.

Acquisition of ChemoCentryx, Inc.

On October 20, 2022, we acquired all the outstanding stock of ChemoCentryx, a publicly traded biotechnology company 
focused on orally-administered therapeutics to treat autoimmune diseases, inflammatory disorders and cancer, for $52.00 per 
share  in  cash,  representing  a  total  consideration  of  $3.9  billion.  The  acquisition,  which  was  accounted  for  as  a  business 
combination, includes TAVNEOS, an orally administered selective complement 5a receptor inhibitor that was approved by the 
U.S.  FDA  in  October  2021  as  an  adjunctive  therapy  for  adults  with  severe  active  anti-neutrophil  cytoplasmic  autoantibody-
associated  vasculitis  (ANCA-associated  vasculitis).  TAVNEOS  is  commercialized  by  us  in  the  United  States;  for  markets 
outside  the  United  States,  TAVNEOS  is  commercialized  by  a  collaboration  partner,  and  Amgen  is  entitled  to  royalties  and 
milestones  based  off  future  sales  of  the  product.  Upon  its  acquisition,  ChemoCentryx  became  a  wholly  owned  subsidiary  of 
Amgen, and its operations have been included in our consolidated financial statements commencing on the acquisition date.

During the three months ended December 31, 2022, the Company incurred approximately $106 million of costs directly 
related to the acquisition of ChemoCentryx, consisting of share-based payments to settle non-vested equity awards attributable 
to post-combination services, severance and other transaction costs. These costs were included primarily in SG&A expense in 
the Consolidated Statements of Income.

The $3.9 billion total consideration consisted of (i) a $3.7 billion cash payment to outstanding common stockholders of 
ChemoCentryx and (ii) a $181 million cash payment to equity award holders of ChemoCentryx for services rendered prior to 
the acquisition date of October 20, 2022, under the ChemoCentryx equity award plans.

The developed-product-technology rights acquired relates to TAVNEOS, which is approved in the United States and EU 
for  ANCA-associated  vasculitis.  The  estimated  fair  values  of  $3.5  billion  were  determined  by  using  a  multi-period  excess 
earnings income approach that discounts expected future cash flows to present value by applying a discount rate that represents 
the estimated rate that market participants would use to value the intangible assets. The developed-product-technology rights 
are being amortized on a straight-line basis over a weighted-average period of approximately 11 years using the straight-line 
method.

The  estimated  fair  value  of  the  acquired  inventory  of  $41  million  was  determined  using  the  comparative  sales  method, 
which uses actual or expected selling prices of inventory as the base amount to which adjustments for selling effort and a profit 
on  the  buyer’s  effort  are  applied.  The  inventory  fair  value  adjustment  is  being  amortized  as  inventory  turns  over,  which  we 
estimate to be approximately 13 months.

A net deferred tax liability of $516 million was recognized on the temporary differences related to the book bases and tax 

bases of the acquired identifiable assets and assumed liabilities, primarily driven by the intangible assets acquired.

The  excess  of  the  acquisition  date  consideration  over  the  fair  values  assigned  to  the  assets  acquired  and  the  liabilities 
assumed of $667 million was recorded as goodwill, which is not deductible for tax purposes. The goodwill value is primarily 
attributable to the expected synergies from the TAVNEOS asset.

Our accounting for this acquisition is preliminary and will be finalized upon completion of our analysis to determine the 
acquisition  date  fair  values  of  certain  assets  acquired,  liabilities  assumed  and  tax-related  items  as  we  obtain  additional 
information during the measurement period of up to one year from the acquisition date.

Acquisition of Teneobio, Inc.

On October 19, 2021, we acquired all of the outstanding stock of Teneobio, a privately held, clinical-stage biotechnology 
company  developing  a  new  class  of  biologics  called  human  heavy-chain  antibodies,  which  are  single-chain  antibodies 
composed  of  the  human  heavy-chain  domain.  The  transaction,  which  was  accounted  for  as  a  business  combination,  includes 
Teneobio’s  proprietary  bispecific  and  multispecific  antibody  technologies,  which  complement  Amgen’s  existing  antibody 
capabilities  and  bispecific  T-cell  engager  BiTE®  platform  and  will  enable  significant  acceleration  and  efficiency  in  the 
discovery  and  development  of  new  molecules  to  treat  diseases  across  Amgen’s  core  therapeutic  areas.  Upon  its  acquisition, 
Teneobio  became  a  wholly  owned  subsidiary  of  Amgen,  and  its  operations  have  been  included  in  our  consolidated  financial 
statements commencing on the acquisition date.

Measurement period adjustments for the year ended December 31, 2022, included changes to the purchase price allocation 
and  total  consideration,  resulting  in  a  net  increase  of  $22  million  to  goodwill.  The  measurement  period  adjustments  resulted 
primarily  from  valuation  inputs  pertaining  to  certain  acquired  assets  based  on  facts  and  circumstances  that  existed  as  of  the 
acquisition date and did not result from events subsequent to the acquisition date. These adjustments did not have a significant 
impact  on  Amgen’s  results  of  operations  during  the  year  ended  December  31,  2022,  and  would  not  have  had  a  significant 
impact on prior-period results if these adjustments had been made as of the acquisition date. The following table summarizes

Consideration for this transaction comprised of (i) an upfront cash payment of $993 million, which included a working-
capital adjustment, and (ii) future contingent milestone payments to Teneobio’s former equity holders of up to $1.6 billion in 
cash, based on the achievement of various development and regulatory milestones with regard to the leading asset (AMG 340, 
formerly  TNB-585)  and  to  various  development  milestones  for  other  drug  candidates.  The  estimated  fair  values  of  the 
contingent  consideration  obligations  aggregated  $299  million  as  of  the  acquisition  date  and  were  determined  using  a 
probability-weighted  expected  return  methodology.  The  assumptions  in  this  method  include  the  probability  of  achieving  the 
milestones and the expected payment dates, with such amounts discounted to present value based on our pretax cost of debt. 
See Note 17, Fair value measurement, for information regarding the estimated fair value of these obligations as of December 
31, 2022.

The estimated fair values of acquired IPR&D assets totaled $991 million, of which $784 million relates to AMG 340, that 
is in a Phase 1 clinical trial for the treatment of metastatic castration-resistant prostate cancer (mCRPC), and the balance relates 
to four separate preclinical oncology programs. The R&D technology rights of $115 million relate to Teneobio’s proprietary 
bispecific  and  multispecific  antibody  technologies;  the  amount  is  being  amortized  over  10  years  by  using  the  straight-line 
method. Teneobio has also licensed its technology and certain identified targets to various third parties, representing contractual 
agreements valued at $41 million. The estimated fair values for these intangible assets were determined using a multi-period 
excess  earnings  income  approach  that  discounts  expected  future  cash  flows  to  present  value  by  applying  a  discount  rate  that 
represents the estimated rate that market participants would use to value the intangible assets. The projected cash flows were 
based on certain assumptions attributable to the respective intangible asset, including estimates of future revenues and expenses, 
the time and resources needed to complete development and the probabilities of obtaining marketing approval from the FDA 
and other regulatory agencies.

A deferred tax liability of $244 million was recognized on temporary differences related to the book bases and tax bases 

of the acquired identifiable assets and assumed liabilities, primarily driven by the intangible assets acquired.

The  excess  of  the  acquisition  date  consideration  over  the  fair  values  assigned  to  the  assets  acquired  and  the  liabilities 
assumed  of  $273  million  was  recorded  as  goodwill,  which  is  not  deductible  for  tax  purposes.  The  goodwill  value  represents 
expected synergies from both AMG 340 and the technologies acquired.

Acquisition of Five Prime Therapeutics, Inc.

On April 16, 2021, Amgen completed its acquisition of Five Prime for a total cash consideration of $1.6 billion, net of 
cash acquired. The purchase price was funded with cash on hand. This transaction was accounted for as an asset acquisition 
because substantially all the value of the assets acquired was concentrated in the intellectual property rights of bemarituzumab, 
a  Phase  3  first-in-class  program  for  gastric  cancer.  Five  Prime’s  operations  have  been  included  in  our  consolidated  financial 
statements commencing after the acquisition date.

We allocated the consideration to acquire Five Prime to the bemarituzumab IPR&D program of $1.5 billion, which was 
expensed  immediately  in  Acquired  IPR&D  expense  in  the  Consolidated  Statements  of  Income;  deferred  tax  assets  of 
$177 million; and other net liabilities of $47 million. The acquired IPR&D expense was not tax deductible.

Divestiture of Gensenta İlaç Sanayi ve Ticaret A.Ş.

On  November  2,  2022,  we  sold  our  shares  in  Gensenta,  a  subsidiary  in  Turkey,  to  Eczacıbaşı  for  net  cash  proceeds  of 
approximately  $130  million.  The  transaction  was  accounted  for  as  a  sale  of  a  business  and  did  not  meet  the  criteria  to  be 
classified  as  discontinued  operations.  Upon  closing  of  this  transaction,  net  assets  related  to  Gensenta  of  $86  million  were 
divested, and during the year ended December 31, 2022, we recognized a loss on divestiture of $567 million recorded in Other 
operating  expenses  in  the  Consolidated  Statements  of  Income,  primarily  due  to  the  reclassification  of  $615  million  of 
cumulative foreign currency translation losses from AOCI into earnings. See Note 16, Stockholders’ equity.

We had product sales to three customers that individually accounted for more than 10% of total revenues for each of the 
years ended December 31, 2022, 2021 and 2020. For the year ended December 31, 2022, on a combined basis, these customers

2022 and 2021, 26% and 27%, respectively, of net trade receivables were due from customers located outside the United States, 
the majority of which were from Europe. Our total allowance for doubtful accounts as of December 31, 2022 and 2021, was not

4. Stock-based compensation

Our  Amended  2009  Plan  authorizes  for  issuance  to  employees  of  Amgen  and  nonemployee  members  of  our  Board  of 
Directors  shares  of  our  common  stock  pursuant  to  grants  of  equity-based  awards,  including  RSUs,  stock  options  and 
performance units. The pool of shares available under the Amended 2009 Plan is reduced by one share for each stock option 
granted and by 1.9 shares for other types of awards granted, including full-value awards. In general, if any shares subject to an 
award granted under the Amended 2009 Plan expire or become forfeited, terminated or canceled without the issuance of shares, 
the shares subject to such awards are added back into the authorized pool on the same basis that they were removed. In addition, 
under the Amended 2009 Plan, shares withheld to pay for minimum statutory tax obligations with respect to full-value awards 
are added back into the authorized pool on the basis of 1.9 shares. As of December 31, 2022, the Amended 2009 Plan provides 
for future grants and/or issuances of up to approximately 15 million shares of our common stock. Stock-based awards under our 
employee compensation plans are made with newly issued shares reserved for this purpose.

The  following  table  reflects  the  components  of  stock-based  compensation  expense  recognized  in  our  Consolidated

Eligible employees generally receive an annual grant of RSUs and, for certain executive-level employees, stock options, 
with  the  size  and  type  of  award  generally  determined  by  the  employee’s  salary  grade  and  performance  level.  Certain 
management  and  professional-level  employees  typically  receive  RSU  grants  upon  commencement  of  employment. 
Nonemployee members of our Board of Directors also receive an annual grant of RSUs.

F-18

 
 
 
 
 
 
 
 
 
 
Our RSU and stock option grants provide for accelerated or continued vesting in certain circumstances as defined in the 
plans and related grant agreements, including upon death, disability, termination in connection with a change in control and the 
retirement  of  employees  who  meet  certain  service  and/or  age  requirements.  RSUs  and  stock  options  generally  vest  in  equal 
amounts on the second, third and fourth anniversaries of the grant date. RSUs accrue dividend equivalents, which are typically 
payable in shares only when and to the extent the underlying RSUs vest and are issued to the recipient.

Restricted stock units

The  grant  date  fair  value  of  an  RSU  equals  the  closing  price  of  our  common  stock  on  the  grant  date,  as  RSUs  accrue 
dividend equivalents during their vesting period. The weighted-average grant date fair values per unit of RSUs granted during 
the years ended December 31, 2022, 2021 and 2020, were $234.47, $233.10 and $235.63, respectively.

The total grant date fair values of RSUs that vested during the years ended December 31, 2022, 2021 and 2020, were $192 

million, $166 million and $161 million, respectively.

Stock options

The  exercise  price  of  stock  options  is  set  as  the  closing  price  of  our  common  stock  on  the  grant  date,  and  the  related 
number  of  shares  granted  is  fixed  at  that  point  in  time.  Awards  expire  10  years  from  the  date  of  grant.  We  use  the  Black–
Scholes option valuation model to estimate the grant date fair value of stock options. 

The weighted-average assumptions used in the option valuation model and the resulting weighted-average grant date fair 

values of stock options granted were as follows:

Closing price of our common stock on grant date

Expected volatility (average of implied and historical volatility)
Expected life (in years)
Risk-free interest rate

The  total  intrinsic  values  of  options  exercised  during  the  years  ended  December  31,  2022,  2021  and  2020,  were  $67 
million, $56 million and $98 million, respectively. The actual tax benefits realized from tax deductions from option exercises 
during the years ended December 31, 2022, 2021 and 2020, were $14 million, $12 million and $21 million, respectively.

As of December 31, 2022, $362 million of unrecognized compensation cost was related to nonvested RSUs and unvested 

stock options, which is expected to be recognized over a weighted-average period of 1.7 years.

Performance units

Certain management-level employees also receive annual grants of performance units, which give the recipient the right to 
receive  common  stock  that  is  contingent  upon  achievement  of  specified  preestablished  goals  over  the  performance  period, 
which is generally three years. The performance goals for the units granted during the years ended December 31, 2022, 2021 
and 2020, which are accounted for as equity awards, are based on (i) Amgen’s stockholder return compared with a comparator 
group of companies, which are considered market conditions and are therefore reflected in the grant date fair values of the units, 
and  (ii)  Amgen’s  stand-alone  financial  performance  measures,  which  are  considered  performance  conditions.  The  expense 
recognized for awards is based on the grant date fair value of a unit multiplied by the number of units expected to be earned 
with respect to the related performance conditions, net of estimated forfeitures. Depending on the outcome of these performance 
goals, a recipient may ultimately earn a number of units greater or less than the number of units granted. Shares of our common 
stock are issued on a one-for-one basis for each performance unit earned. In general, performance unit awards vest at the end of 
the performance period. The performance award program provides for accelerated or continued vesting in certain circumstances 
as  defined  in  the  plan,  including  upon  death,  disability,  a  change  in  control  and  retirement  of  employees  who  meet  certain 
service and/or age requirements. Performance units accrue dividend equivalents that are typically payable in shares only when 
and to the extent the underlying performance units vest and are issued to the recipient, including with respect to market and 
performance conditions that affect the number of performance units earned.

We  use  a  payout  simulation  model  to  estimate  the  grant  date  fair  value  of  performance  units.  The  weighted-average 
assumptions used in the payout simulation model and the resulting weighted-average grant date fair values of performance units 
granted were as follows:

The payout simulation model assumes correlations of returns of the stock prices of our common stock and the common 
stocks of the comparator groups of companies and stock price volatilities of the comparator groups of companies to simulate 
stockholder returns over the performance periods and their resulting impact on the payout percentages based on the contractual 
terms of the performance units.

F-20

 
 
 
 
 
 
 
As of both December 31, 2022 and 2021, 1.6 million performance units were outstanding, with weighted-average grant 
date fair values per unit of $250.27 and $229.39 per unit, respectively. During the year ended December 31, 2022, 0.6 million 
performance units with a weighted-average grant date fair value per unit of $247.48 were granted, and 0.1 million performance 
units with a weighted-average grant date fair value per unit of $250.94 were forfeited.

The total fair values of performance units paid during the years ended December 31, 2022, 2021 and 2020, were $150 
million,  $149  million  and  $230  million,  respectively,  based  on  the  number  of  performance  units  earned  multiplied  by  the 
closing stock price of our common stock on the last day of the performance period.

As of December 31, 2022, $132 million of unrecognized compensation cost was related to nonvested performance units, 

which is expected to be recognized over a weighted-average period of one year. 

5. Defined contribution plan

The Company has defined contribution plans to which certain employees of the Company and participating subsidiaries 
may  defer  compensation  for  income  tax  purposes.  Participants  are  eligible  to  receive  matching  contributions  based  on  their 
contributions, in addition to other Company contributions. Defined contribution plan expenses were $243 million, $279 million 
and $231 million for the years ended December 31, 2022, 2021 and 2020, respectively.

Deferred income taxes reflect the tax effect of temporary differences between the carrying amounts of assets and liabilities 
for financial reporting purposes and the amounts used for income tax purposes, tax credit carryforwards and the tax effects of 
NOL carryforwards. As of December 31, 2022, we elected to establish deferred taxes with respect to the U.S. minimum tax on 
the  earnings  of  our  foreign  subsidiaries  for  the  reversal  of  temporary  items  in  future  years.  Significant  components  of  our 
deferred tax assets and liabilities were as follows (in millions):

Valuation allowances are provided to reduce the amounts of our deferred tax assets to an amount that is more likely than 
not  to  be  realized  based  on  an  assessment  of  positive  and  negative  evidence,  including  estimates  of  future  taxable  income 
necessary to realize future deductible amounts.

The valuation allowance increased in 2022, primarily driven by the Company’s expectation that certain state R&D credits 

will expire unused.

As  of  December  31,  2022,  we  had  $170  million  of  federal  tax  credit  carryforwards  available  to  reduce  future  federal 
income taxes and have provided a valuation allowance for $6 million of those federal tax credit carryforwards. The federal tax 
credit carryforwards expire between 2023 and 2042. We had $896 million of state tax credit carryforwards available to reduce 
future state income taxes and have provided a valuation allowance for $813 million of those state tax credit carryforwards. We 
had $51 million of tax credit carryforwards related to our foreign jurisdictions available to offset future foreign income taxes for 
which we have provided no valuation allowance. 

As of December 31, 2022, we had $1.3 billion of federal NOL carryforwards available to reduce future federal income 
taxes and have provided no valuation allowance on those federal NOL carryforwards. Additionally, $1.0 billion of those federal 
NOL carryforwards have no expiration; the remainder begin to expire between 2023 and 2037. We had $536 million of state 
NOL carryforwards available to reduce future state income taxes and have provided a valuation allowance for $415 million of 
those state NOL carryforwards. We had $1.9 billion of foreign NOL carryforwards available to reduce future foreign income 
taxes  and  have  provided  a  valuation  allowance  for  $186  million  of  those  foreign  NOL  carryforwards.  For  the  foreign  NOLs 
with no valuation allowance provided, $640 million have no expiration; and the remainder will expire between 2023 and 2051.

The reconciliations of the total gross amounts of UTBs were as follows (in millions):

Substantially all of the UTBs as of December 31, 2022, if recognized, would affect our effective tax rate. During the year 
ended December 31, 2020, we effectively settled certain issues with the IRS. As a result, we remeasured our UTBs accordingly.

Interest and penalties related to UTBs are included in our provision for income taxes. During the years ended December 
31,  2022,  2021  and  2020,  we  recognized  $189  million,  $98  million  and  $116  million,  respectively,  of  interest  and  penalties 
through the income tax provision in the Consolidated Statements of Income. The increase in interest expense for the year ended 
December  31,  2022,  was  primarily  due  to  higher  interest  rates  during  2022.  As  of  December  31,  2022  and  2021,  accrued 
interest and penalties associated with UTBs were $1.1 billion and $881 million, respectively.

The reconciliations between the federal statutory tax rate applied to income before income taxes and our effective tax rate 

were as follows:

Foreign-derived intangible income

Credits, Puerto Rico excise tax

Interest on uncertain tax positions

The  effective  tax  rates  for  the  years  ended  December  31,  2022,  2021  and  2020,  differ  from  the  federal  statutory  rate 
primarily due to impacts of the jurisdictional mix of income and expenses. Substantially all of the benefit to our effective tax 
rate from foreign earnings results from the Company’s operations in Puerto Rico, a territory of the United States that is treated 
as a foreign jurisdiction for U.S. tax purposes. Our operations in Puerto Rico are subject to tax incentive grants through 2050. 
Additionally, the Company’s operations conducted in Singapore are subject to a tax incentive grant through 2034. Our foreign 
earnings are also subject to U.S. tax at a reduced rate of 10.5%.

The U.S. territory of Puerto Rico imposes a 4% excise tax on the gross intercompany purchase price of goods and services 
from  our  manufacturer  in  Puerto  Rico  effective  through  December  31,  2022.  For  2022,  we  account  for  the  excise  tax  as  a 
manufacturing cost that is capitalized in Inventories and expensed in Cost of sales when the related products are sold. For U.S. 
income tax purposes, the excise tax results in foreign tax credits that are generally recognized in our provision for income taxes 
when the excise tax is incurred. 

Income taxes paid during the years ended December 31, 2022, 2021 and 2020, were $2.4 billion, $1.9 billion and $1.4 

billion, respectively.

One or more of our legal entities file income tax returns in the U.S. federal jurisdiction, various U.S. state jurisdictions 
and  certain  foreign  jurisdictions.  Our  income  tax  returns  are  routinely  examined  by  tax  authorities  in  those  jurisdictions. 
Significant disputes can and have arisen with tax authorities involving issues regarding the timing and amount of deductions, 
the  use  of  tax  credits  and  allocations  of  income  and  expenses  among  various  tax  jurisdictions  because  of  differing 
interpretations of tax laws, regulations and relevant facts. Tax authorities, including the IRS, are becoming more aggressive and 
are particularly focused on such matters. 

In  2017,  we  received  an  RAR  and  a  modified  RAR  from  the  IRS  for  the  years  2010–2012,  proposing  significant 
adjustments  that  primarily  relate  to  the  allocation  of  profits  between  certain  of  our  entities  in  the  United  States  and  the  U.S. 
territory  of  Puerto  Rico.  We  disagreed  with  the  proposed  adjustments  and  calculations  and  pursued  resolution  with  the  IRS 
appeals  office  but  were  unable  to  reach  resolution.  In  July  2021,  we  filed  a  petition  in  the  U.S.  Tax  Court  to  contest  two 
duplicate Statutory Notices of Deficiency (Notices) for the years 2010–2012 that we received in May and July 2021, which seek 
to  increase  our  U.S.  taxable  income  for  the  years  2010–2012  by  an  amount  that  would  result  in  additional  federal  tax  of 
approximately $3.6 billion plus interest. Any additional tax that could be imposed for the years 2010–2012 would be reduced 
by up to approximately $900 million of repatriation tax previously accrued on our foreign earnings.

In  2020,  we  received  an  RAR  and  a  modified  RAR  from  the  IRS  for  the  years  2013–2015,  also  proposing  significant 
adjustments  that  primarily  relate  to  the  allocation  of  profits  between  certain  of  our  entities  in  the  United  States  and  the  U.S. 
territory of Puerto Rico similar to those proposed for the years 2010–2012. We disagreed with the proposed adjustments and 
calculations and pursued resolution with the IRS appeals office but were unable to reach resolution. In July 2022, we filed a 
petition in the U.S. Tax Court to contest a Notice for the years 2013–2015 that we previously reported receiving in April 2022 
that seeks to increase our U.S. taxable income for the years 2013–2015 by an amount that would result in additional federal tax 
of  approximately  $5.1  billion,  plus  interest.  In  addition,  the  Notice  asserts  penalties  of  approximately  $2.0  billion.  Any 
additional  tax  that  could  be  imposed  for  the  years  2013–2015  would  be  reduced  by  up  to  approximately  $2.2  billion  of 
repatriation tax previously accrued on our foreign earnings.

We firmly believe that the IRS positions set forth in the 2010–2012 and 2013–2015 Notices are without merit. We are 
contesting the 2010–2012 and 2013–2015 Notices through the judicial process. The two cases were consolidated in U.S. Tax 
Court on December 19, 2022.

We  are  currently  under  examination  by  the  IRS  for  the  years  2016–2018  with  respect  to  issues  similar  to  those  for  the 

2010 through 2015 period. In addition, we are under examination by a number of state and foreign tax jurisdictions.

Final resolution of these complex matters is not likely within the next 12 months. We continue to believe our accrual for 
income tax liabilities is appropriate based on past experience, interpretations of tax law, application of the tax law to our facts 
and judgments about potential actions by tax authorities; however, due to the complexity of the provision for income taxes and 
uncertain resolution of these matters, the ultimate outcome of any tax matters may result in payments substantially greater than 
amounts accrued and could have a material adverse impact on our consolidated financial statements.

We are no longer subject to U.S. federal income tax examinations for years ended on or before December 31, 2009.

7. Earnings per share

The  computation  of  basic  EPS  is  based  on  the  weighted-average  number  of  our  common  shares  outstanding.  The 
computation of diluted EPS is based on the weighted-average number of our common shares outstanding and dilutive potential 
common shares, which primarily include shares that may be issued under our stock option, restricted stock and performance 
unit award programs (collectively, dilutive securities), as determined by using the treasury stock method.

The computations for basic and diluted EPS were as follows (in millions, except per-share data):

Income (Numerator):

Net income for basic and diluted EPS

Shares (Denominator):

Weighted-average shares for basic EPS

Effect of dilutive securities

8. Collaborations

A  collaborative  arrangement  is  a  contractual  arrangement  that  involves  a  joint  operating  activity.  Such  arrangements 
involve two or more parties that are both (i) active participants in the activity and (ii) exposed to significant risks and rewards 
dependent on the commercial success of the activity.

From  time  to  time,  we  enter  into  collaborative  arrangements  for  the  R&D,  manufacture  and/or  commercialization  of 
products and/or product candidates. These collaborations generally provide for nonrefundable upfront license fees, development 
and commercial-performance milestone payments, cost sharing, royalties and/or profit sharing. Our collaboration arrangements 
are performed with no guarantee of either technological or commercial success, and each arrangement is unique in nature. See 
Note  1,  Summary  of  significant  accounting  policies,  for  additional  discussion  of  revenues  recognized  under  these  types  of 
arrangements. Operating expenses for costs incurred pursuant to these arrangements are reported in their respective expense line 
items  in  the  Consolidated  Statements  of  Income,  net  of  any  payments  due  to  or  reimbursements  due  from  our  collaboration 
partners,  with  such  reimbursements  being  recognized  at  the  time  the  party  becomes  obligated  to  pay.  Our  significant 
arrangements are discussed below.

BeiGene, Ltd.

In January 2020, we acquired an equity stake in BeiGene for approximately $2.8 billion in cash as part of a collaboration 
to expand our oncology presence in China. For additional information regarding our equity investment in BeiGene, see Note 9, 
Investments. Under the collaboration, BeiGene began selling XGEVA in 2020, BLINCYTO in 2021 and KYPROLIS in 2022 
in China, and Amgen shares profits and losses equally during the initial product-specific commercialization periods; thereafter, 
product  rights  may  revert  to  Amgen,  and  Amgen  will  pay  royalties  to  BeiGene  on  sales  in  China  of  such  products  for  a 
specified period. Amgen manufactures and supplies the collaboration products to BeiGene.

In addition, we jointly develop a portion of our oncology portfolio with BeiGene, which shares in global R&D costs by 
providing  cash  and  development  services  of  up  to  $1.25  billion.  Upon  regulatory  approval,  BeiGene  will  assume 
commercialization  rights  in  China  for  a  specified  period,  and  Amgen  and  BeiGene  will  share  profits  equally  until  certain  of 
these product rights revert to Amgen. Upon return of the product rights, Amgen will pay royalties to BeiGene on sales in China 
for a specified period. For product sales outside China, Amgen will also pay royalties to BeiGene.

During  the  years  ended  December  31,  2022,  2021  and  2020,  net  costs  recovered  from  BeiGene  for  oncology  product 
candidates were $199 million, $220 million and $225 million, respectively, and were recorded as an offset to R&D expense in 
the Consolidated Statements of Income. During the years ended December 31, 2022 and 2021, product sales from Amgen to 

F-25

 
 
 
 
 
 
 
 
 
BeiGene  under  the  collaboration  were  $64  million  and  $72  million,  respectively,  and  were  recorded  in  Product  sales  in  the 
Consolidated  Statements  of  Income.  During  the  years  ended  December  31,  2022  and  2021,  profit  and  loss  share  expenses 
related  to  the  initial  product-specific  commercialization  period  were  $53  million  and  $64  million,  respectively,  and  were 
recorded in SG&A expense in the Consolidated Statements of Income. Product sales from Amgen to BeiGene and profit and 
loss  share  expenses  were  not  material  during  the  year  ended  December  31,  2020.  Amounts  owed  from  BeiGene  for  product 
sales  were  $6  million  and  $21  million  as  of  December  31,  2022  and  2021,  respectively,  which  are  included  in  Trade 
receivables, net, in the Consolidated Balance Sheets. Net amounts owed from BeiGene for cost recoveries and profit and loss 
share payments were $47 million and $61 million as of December 31, 2022 and 2021, respectively, which are included in Other 
current assets in the Consolidated Balance Sheets.

AstraZeneca plc

We  are  in  a  collaboration  with  AstraZeneca  for  the  development  and  commercialization  of  TEZSPIRE.  Under  our 
collaboration, both companies share global costs, profits and losses equally after payment by AstraZeneca of a mid-single-digit 
royalty to Amgen. AstraZeneca leads global development, and both Amgen and AstraZeneca jointly commercialize TEZSPIRE 
in North America. In North America, Amgen, as the principal, recognizes product sales of TEZSPIRE in the United States, and 
AstraZeneca,  as  the  principal,  recognizes  product  sales  of  TEZSPIRE  in  Canada.  AstraZeneca  leads  commercialization  for 
TEZSPIRE outside North America. Amgen manufactures and supplies TEZSPIRE worldwide.

During the years ended December 31, 2022, 2021 and 2020, net costs due to AstraZeneca for global development were 
$74 million, $49 million and $52 million, respectively, and were recorded in R&D Expense in the Consolidated Statements of 
Income. During the years ended December 31, 2022, 2021 and 2020, net costs due to AstraZeneca for global commercialization 
were  $60  million,  $39  million  and  $16  million,  respectively,  and  were  recorded  in  SG&A  Expense  in  the  Consolidated 
Statements of Income. During the year ended December 31, 2022, global profit and loss share expenses were $119 million and 
were recorded primarily in Cost of sales in the Consolidated Statements of Income. TEZSPIRE launched in the United States in 
January 2022.

UCB

We are in a collaboration with UCB for the development and commercialization of EVENITY. Under our collaboration, 
UCB  has  rights  to  lead  commercialization  for  EVENITY  in  most  countries  in  Europe  and  China  (excluding  Hong  Kong). 
Amgen, as the principal, leads commercialization for EVENITY and recognizes product sales in all other territories, including 
the  United  States.  Global  development  costs  and  commercialization  profits  and  losses  related  to  the  collaboration  are  shared 
equally. Amgen manufactures and supplies EVENITY worldwide.

During  the  years  ended  December  31,  2022,  2021  and  2020,  global  profit  and  loss  share  expenses  were  $255  million, 
$186 million and $115 million, respectively, and were recorded primarily in Cost of sales in the Consolidated Statements of 
Income.  Net  costs  recovered  from  and  due  to  UCB  during  the  years  ended  December  31,  2022,  2021  and  2020,  were  not 
material.

Novartis Pharma AG

We  are  in  a  collaboration  with  Novartis  to  jointly  develop  and  commercialize  Aimovig.  On  January  31,  2022,  we 
modified the terms of the collaboration. Effective January 1, 2022, in the United States, Novartis no longer collaborates with 
Amgen,  shares  Aimovig  commercialization  costs  or  is  required  to  pay  milestones,  and  Amgen  no  longer  pays  royalties  to 
Novartis on U.S. sales of Aimovig. Novartis continues to hold global co-development rights and exclusive commercial rights 
outside the United States and Japan for Aimovig. Amgen and Novartis share global development expenses, and Novartis pays 
Amgen double-digit royalties on net sales of the product outside the United States and Japan. Amgen manufactures and supplies 
Aimovig worldwide.

During the year ended December 31, 2022, net costs recovered from Novartis for migraine products were $53 million and 
were  recorded  in  R&D  expense  in  the  Consolidated  Statements  of  Income.  During  the  years  ended  December  31,  2021  and 
2020,  net  costs  recovered  from  Novartis  for  migraine  products  were  $160  million  and  $192  million,  respectively,  and  were 
recorded primarily in SG&A expense in the Consolidated Statements of Income. During the years ended December 31, 2021 
and 2020, royalties due to Novartis for Aimovig were $116 million and $139 million, respectively, and were recorded in Cost 
of sales in the Consolidated Statements of Income. During the years ended December 31, 2022, 2021 and 2020, royalties due 
from Novartis for Aimovig were not material.

F-26

Kyowa Kirin Co., Ltd.

On July 30, 2021, we closed our collaboration and licensing agreement with KKC to jointly develop and commercialize 
rocatinlimab, an anti-OX40 fully human monoclonal antibody, worldwide, except in Japan. Rocatinlimab is for the treatment of 
atopic dermatitis, with potential for treatment of other autoimmune diseases.

Under the terms of the agreement, we lead the global development, manufacture and commercialization of rocatinlimab, 
except  in  Japan.  KKC  will  co-promote  rocatinlimab  with  Amgen  in  the  United  States  and  have  opt  in  rights  to  co-promote 
rocatinlimab in various other markets outside the United States, including in Europe and Asia.

We made an upfront payment of $400 million to KKC that was recognized in R&D expense in the third quarter of 2021. 
Amgen and KKC share equally the global development costs, except in Japan, and the U.S. commercialization costs. Outside 
the  United  States  and  Japan,  any  commercialization  costs  incurred  by  KKC  will  be  reimbursed  by  Amgen.  We  may  also  be 
required to make milestone payments of up to $850 million contingent upon the achievement of certain regulatory events and 
commercial  thresholds.  We  will  also  pay  KKC  significant  double-digit  royalties  on  global  sales,  except  in  Japan.  Net  costs 
recovered from and due to KKC were not material during the years ended December 31, 2022 and 2021.

Other

In addition to the collaborations discussed above, we have various other collaborations that are not individually significant 
to our business at this time. Pursuant to the terms of those agreements, we may be required to pay additional amounts or we 
may receive additional amounts upon the achievement of various development and commercial milestones that in the aggregate 
could be significant. We may also incur or have reimbursed to us significant R&D costs if a related product candidate were to 
advance to late-stage clinical trials. In addition, if any products related to these collaborations are approved for sale, we may be 
required  to  pay  significant  royalties  or  we  may  receive  significant  royalties  on  future  sales.  The  payments  of  these  amounts, 
however, are contingent upon the occurrence of various future events that have high degrees of uncertainty of occurrence.

All interest-bearing securities as of December 31, 2022 and 2021, mature in one year or less.

For the years ended December 31, 2022, 2021 and 2020, realized gains and losses on interest-bearing securities were not

Consolidated Statements of Income. The cost of securities sold is based on the specific-identification method.

The  primary  objective  of  our  investment  portfolio  is  to  maintain  safety  of  principal,  prudent  levels  of  liquidity  and 
acceptable levels of risk. Our investment policy limits interest-bearing security investments to certain types of debt and money 
market  instruments  issued  by  institutions  with  investment-grade  credit  ratings,  and  it  places  restrictions  on  maturities  and 
concentration by asset class and issuer.

Equity securities

We held investments in equity securities with readily determinable fair values (publicly traded securities) of $480 million 
and  $611  million  as  of  December  31,  2022  and  2021,  respectively,  which  are  included  in  Other  noncurrent  assets  in  the 
Consolidated  Balance  Sheets.  For  the  years  ended  December  31,  2022,  2021  and  2020,  net  unrealized  gains  and  losses  on 
publicly traded securities were a loss of $165 million and gains of $161 million and $174 million, respectively. Realized gains 
and losses on publicly traded securities for the years ended December 31, 2022, 2021 and 2020, were not material. 

We held investments of $233 million and $262 million in equity securities without readily determinable fair values as of 
December 31, 2022 and 2021, respectively, which are included in Other noncurrent assets in the Consolidated Balance Sheets. 
For  the  years  ended  December  31,  2022  and  2020,  gains  due  to  upward  adjustments  and  gains  realized  upon  dispositions  of

and gains realized on the dispositions of these securities were $41 million. For the year ended December 31, 2022, downward 
adjustments  to  the  carrying  values  of  these  securities  were  $67  million.  For  the  years  ended  December  31,  2021  and  2020, 
downward adjustments were not material. Adjustments were based on observable price transactions.

Equity Method Investments

BeiGene, Ltd.

On  January  2,  2020,  we  acquired  a  20.5%  ownership  interest  in  BeiGene  for  $2.8  billion,  of  which  $2.6  billion  was 
attributed  to  the  fair  value  of  equity  securities  upon  closing,  with  the  remainder  attributed  to  prepaid  R&D.  Our  equity 
investment in BeiGene is included in Other noncurrent assets in the Consolidated Balance Sheets. As of December 31, 2022, 
our equity investment is accounted for under the equity method of accounting due to our ability to exert significant influence 
over BeiGene. See Note 1, Summary of significant accounting policies, for factors in concluding our ability to exert significant 
influence over BeiGene. The fair value of equity securities acquired exceeded our proportionate share of the carrying value of 
the underlying net assets of BeiGene by approximately $2.4 billion. The equity method of accounting requires us to identify and 
allocate  amounts  to  items  that  give  rise  to  the  basis  difference  and  to  amortize  these  items  over  their  useful  lives.  This 
amortization, along with our share of the results of operations of BeiGene, is included in Other (expense) income, net, in our 
Consolidated Statements of Income. Recognition occurs one quarter in arrears, which began in the second quarter of 2020. The 
basis  difference  was  allocated  to  finite-lived  intangible  assets,  indefinite-lived  intangible  assets,  equity-method  goodwill  and 
related deferred taxes. The finite-lived intangible assets are being amortized over a period ranging from 8 to 15 years.

During  the  years  ended  December  31,  2022,  2021  and  2020,  the  carrying  value  of  the  investment  was  reduced  by  our 
share  of  BeiGene’s  net  losses  of  $394  million,  $265  million  and  $229  million,  respectively,  and  amortization  of  the  basis 
difference of $190 million, $172 million and $109 million, respectively. During the years ended December 31, 2021 and 2020, 
we increased the carrying value by $50 million and $569 million, respectively, as a result of our purchases of additional shares 
of BeiGene; we did not purchase additional shares of BeiGene during the year ended December 31, 2022. In addition, during 
the years ended December 31, 2022, 2021 and 2020, the carrying value increased by $11 million, $265 million and $34 million, 
respectively, from the impact of other BeiGene ownership transactions.

As  of  December  31,  2022  and  2021,  our  ownership  interest  in  BeiGene  was  approximately  18.2%  and  18.4%, 
respectively. As of December 31, 2022 and 2021, the carrying value of our investment in BeiGene was $2.2 billion and $2.8 
billion, respectively. As of December 31, 2022 and 2021, the fair value of our investment in BeiGene was $4.2 billion and $5.1 
billion, respectively. We believe that as of December 31, 2022, the carrying value of our equity investment in BeiGene is fully 
recoverable. For information on a collaboration agreement we entered into with BeiGene in connection with this investment, 
see Note 8, Collaborations.

Effective January 30, 2023, we relinquished our right to appoint a director to BeiGene’s Board of Directors. We no longer 
have the ability to exert significant influence over BeiGene and therefore will account for our equity investment at fair value, 
with changes in fair value recorded in earnings starting in the first quarter of 2023.

Neumora Therapeutics, Inc.

 On September 30, 2021, we acquired an approximately 25.9% ownership interest in Neumora, a privately held company, 
for  $257  million,  which  is  included  in  Other  noncurrent  assets  in  the  Consolidated  Balance  Sheets,  in  exchange  for  a 
$100 million cash payment and $157 million in noncash consideration primarily related to future services. Although our equity 
investment provides us with the ability to exercise significant influence over Neumora, we have elected the fair value option to 
account  for  our  equity  investment.  Under  the  fair  value  option,  changes  in  the  fair  value  of  the  investment  are  recognized 
through  earnings  each  reporting  period.  We  believe  the  fair  value  option  best  reflects  the  economics  of  the  underlying 
transaction. During the year ended December 31, 2022, we made an additional $10 million cash investment via participation in 
Neumora’s  subsequent  financing  round.  As  of  December  31,  2022  and  2021,  our  ownership  interest  in  Neumora  was 
approximately  24.9%  and  25.9%,  respectively,  and  the  fair  value  of  our  investment  was  $335  million  and  $220  million, 
respectively. During the years ended December 31, 2022 and 2021, we recognized a net gain of $105 million and a net loss of 
$37  million,  respectively,  for  the  change  in  fair  values  in  Other  (expense)  income,  net,  in  the  Consolidated  Statements  of 
Income. For information on determination of fair values, see Note 17, Fair value measurement.

Limited partnerships

We  held  limited  partnership  investments  of  $249  million  and  $573  million  as  of  December  31,  2022  and  2021, 
respectively, which are included in Other noncurrent assets in the Consolidated Balance Sheets. These investments, which are 
primarily  investment  funds  of  early-stage  biotechnology  companies,  are  accounted  for  by  using  the  equity  method  of 
accounting and are measured by using our proportionate share of the net asset values of the underlying investments held by the 
limited  partnerships  as  a  practical  expedient.  These  investments  are  typically  redeemable  only  through  distributions  upon 
liquidation  of  the  underlying  assets.  As  of  December  31,  2022,  unfunded  additional  commitments  to  be  made  for  these 
investments during the next several years were $187 million. For the years ended December 31, 2022, 2021 and 2020, net gains 
and losses recognized from our limited partnership investments were a net loss of $284 million and net gains of $143 million 
and $241 million, respectively.

Developed-product-technology rights consists of rights related to marketed products acquired in acquisitions. Licensing 
rights  consists  primarily  of  contractual  rights  acquired  in  acquisitions  to  receive  future  milestone,  royalty  and  profit-sharing 
payments; capitalized payments to third parties for milestones related to regulatory approvals to commercialize products; and 
up-front  payments  associated  with  royalty  obligations  for  marketed  products.  Marketing-related  rights  consists  primarily  of 
rights related to the sale and distribution of marketed products. R&D technology rights pertains to technologies used in R&D 
that  have  alternative  future  uses.  Developed-product-technology  rights  include  assets  acquired  with  the  ChemoCentryx 
acquisition. IPR&D, R&D technology rights and licensing rights includes assets acquired with the Teneobio acquisition. See 
Note 2, Acquisitions and divestitures.

IPR&D consists of R&D projects acquired in a business combination that are not complete at the time of acquisition due 
to remaining technological risks and/or lack of receipt of required regulatory approvals. All IPR&D projects have major risks 
and uncertainties associated with the timely and successful completion of the development and commercialization of product 
candidates, including our ability to confirm safety and efficacy based on data from clinical trials, our ability to obtain necessary 
regulatory approvals and our ability to successfully complete these tasks within budgeted costs. We are not permitted to market 
a  human  therapeutic  without  obtaining  regulatory  approvals,  and  such  approvals  require  the  completion  of  clinical  trials  that 
demonstrate  that  a  product  candidate  is  safe  and  effective.  In  addition,  the  availability  and  extent  of  coverage  and 
reimbursement  from  third-party  payers,  including  government  healthcare  programs  and  private  insurance  plans  as  well  as 
competitive product launches, affect the revenues a product can generate. Consequently, the eventual realized values, if any, of 
acquired  IPR&D  projects  may  vary  from  their  estimated  fair  values.  We  review  IPR&D  projects  for  impairment  annually, 
whenever  events  or  changes  in  circumstances  indicate  that  the  carrying  amounts  may  not  be  recoverable  and  upon  the 
establishment of technological feasibility or regulatory approval.

During the years ended December 31, 2022, 2021 and 2020, we recognized amortization associated with our finite-lived 
intangible  assets  of  $2.6  billion,  $2.6  billion  and  $2.8  billion,  respectively.  Amortization  of  intangible  assets  is  included 
primarily  in  Cost  of  sales  in  the  Consolidated  Statements  of  Income.  The  total  estimated  amortization  for  our  finite-lived 
intangible  assets  for  the  years  ending  December  31,  2023,  2024,  2025,  2026  and  2027,  are  $2.8  billion,  $2.7  billion,  $2.5 
billion, $2.1 billion and $2.1 billion, respectively.

13. Leases

We lease certain facilities and equipment related primarily to R&D, administrative and commercial activities. Leases with 

terms of 12 months or less are expensed as incurred and are not recorded in the Consolidated Balance Sheets.

Most leases include one or more options to renew, with renewal terms that may extend the lease term up to seven years. 
The  exercise  of  lease  renewal  options  is  at  our  sole  discretion.  In  addition,  some  of  our  lease  agreements  include  rental 
payments  adjusted  periodically  for  inflation.  Our  lease  agreements  neither  contain  residual  value  guarantees  nor  impose 
significant restrictions or covenants. We sublease certain real estate to third parties. Our sublease portfolio consists of operating 
leases from former R&D and administrative space.

triggering event we may be required to purchase all or a portion of these debt securities at prices equal to 101% of the principal 
amounts of the notes plus accrued and unpaid interest. In addition, all of our outstanding notes—except our 0.41% 2023 Swiss 
franc  Bonds  and  Other  notes  due  2097—may  be  redeemed  at  any  time  at  our  option—in  whole  or  in  part—at  the  principal 
amounts  of  the  notes  being  redeemed  plus  accrued  and  unpaid  interest  and  make-whole  amounts,  which  are  defined  by  the 
terms of the notes. Certain of the redeemable notes do not require the payment of make-whole amounts if redeemed during a 
specified period of time immediately prior to the maturity of the notes. Such time periods range from one month to six months 
prior to maturity.

Notes, $1.0 billion of the 4.875% 2053 Notes and $1.25 billion of the 4.40% 2062 Notes. The 3.00% 2029 Notes were 
issued to finance eligible projects that meet specified criteria to reduce our impact on the environment.

In 2021, we issued $5.0 billion of debt consisting of $1.25 billion of the 1.65% 2028 Notes, $1.25 billion of the 2.00% 
2032 Notes, $1.15 billion of the 2.80% 2041 Notes and $1.35 billion of the 3.00% 2052 Notes. 

In 2020, we issued $9.0 billion of debt consisting of $500 million of the 1.90% 2025 Notes, $1.75 billion of the 2.20% 
2027 Notes, $1.25 billion of the 2.45% 2030 Notes, $1.25 billion of the 2.30% 2031 Notes, $2.0 billion of the 3.15% 2040 
Notes and $2.25 billion of the 3.375% 2050 Notes.

Debt extinguishment

In  2022,  we  repurchased  portions  of  the  2.20%  2027  Notes,  the  1.65%  2028  Notes,  the  2.00%  2032  Notes,  the  2.80% 
2041 Notes and the 3.00% 2052 Notes for an aggregate cost of $297 million, which resulted in the recognition of a $78 million 
gain on extinguishment of debt recorded in Other (expense) income, net, in the Consolidated Statements of Income.

Debt repayments/redemptions

•

•

•

We made debt repayments/redemptions during the years ended December 31, 2022, 2021 and 2020, as follows:

In 2022, no debt was repaid/redeemed.

In  2021,  we  redeemed  $4.2  billion  of  debt,  including  the  €1.25  billion  aggregate  principal  amount  ($1.4  billion  upon 
settlement of the related cross-currency swap) of the 1.25% 2022 euro Notes, the $500 million aggregate principal amount 
of  the  2.70%  2022  Notes,  the  $1.5  billion  aggregate  principal  amount  of  the  2.65%  2022  Notes  and  the  $750  million 
aggregate principal amount of the 3.625% 2022 Notes. In connection with the redemption of these notes, we paid a total 
of $24 million in make-whole amounts plus associated accrued and unpaid interest, all of which was recognized in Interest 
expense, net, in the Consolidated Statements of Income.

In  2020,  we  repaid/redeemed  $6.5  billion  of  debt,  including  the  repayment  at  maturity  of  the  $300  million  aggregate 
principal amount of the 4.50% 2020 Notes, the $750 million aggregate principal amount of the 2.125% 2020 Notes, the 
$300 million Floating Rate Notes due 2020 and the $700 million aggregate principal amount of the 2.20% 2020 Notes. In 
connection with the redemption of the $900 million aggregate principal amount of the 3.45% 2020 Notes, the $1.0 billion 
aggregate  principal  balance  of  the  4.10%  2021  Notes,  the  $750  million  aggregate  principal  balance  of  the  1.85%  2021 
Notes and the $1.75 billion aggregate principal balance of the 3.875% 2021 Notes, we paid a total of $96 million in make-
whole amounts plus associated accrued and unpaid interest, all of which was recognized in Interest expense, net, in the 
Consolidated Statements of Income.

Interest rate swaps

To achieve a desired mix of fixed-rate and floating-rate debt, we entered into interest rate swap contracts that effectively 
converted fixed-rate interest coupons for certain of our debt issuances to floating LIBOR-based coupons over the lives of the 
respective notes. These interest rate swap contracts qualified and are designated as fair value hedges.

During the year ended December 31, 2021, we entered into interest rate swap contracts with an aggregate notional amount 
of  $1.0  billion  with  respect  to  the  2.45%  2030  Notes  and  an  aggregate  notional  amount  of  $500  million  with  respect  to  the 
2.30% 2031 Notes. In connection with the redemption of the 3.625% 2022 Notes, discussed above, associated interest rate swap 
contracts with an aggregate notional amount of $750 million were terminated.

F-36

In  connection  with  the  redemption  of  certain  of  the  notes  during  the  year  ended  December  31,  2020,  discussed  above, 
associated interest rate swap contracts with an aggregate notional value of $3.65 billion were terminated. In addition, because of 
historically low interest rates, during the year ended December 31, 2020, we terminated interest rate swaps with an aggregate 
notional  amount  of  $5.2  billion  that  hedged  the  3.625%  2024  Notes,  the  2.60%  2026  Notes,  the  4.663%  2051  Notes  and 
portions  of  the  3.625%  2022  Notes  and  the  3.125%  2025  Notes,  which  resulted  in  the  receipt  of  $576  million  of  cash  and 
reduced counterparty credit risk. Immediately following the terminations of these contracts, we entered into new interest rate 
swap  agreements  at  then-current  interest  rates  on  the  same  $5.2  billion  principal  amount  of  notes.  See  Note  18,  Derivative 
instruments.

As of December 31, 2022 and 2021, the effective interest rates on notes for which we have entered into interest rate swap 

contracts and the related notional amounts of these contracts were as follows (dollar amounts in millions):

In 2020, we completed a private offering to exchange portions of certain outstanding senior notes due 2037 through 2043 
(collectively,  Old  Notes),  listed  below,  for  the  $940  million  principal  amount  of  the  newly  issued  2.77%  2053  Notes  (the 
Exchange Offer).

The  following  principal  amounts  of  each  series  of  Old  Notes  were  validly  tendered  and  subsequently  canceled  in 

connection with the Exchange Offer (in millions):

6.375% 2037 Notes

The  2.77%  2053  Notes  bear  interest  at  a  lower  fixed  coupon  rate  while  requiring  higher  principal  repayment  at  a  later 
maturity date as compared to those of the Old Notes that were exchanged. There were no other significant changes to the terms 
between the Old Notes and the 2.77% 2053 Notes. In connection with the Exchange Offer, $85 million was paid to holders of 
the Old Notes (the cash consideration).

The Exchange Offer was accounted for as a debt modification, and accordingly, deferred financing costs and discounts 
associated with the Old Notes, the cash consideration and the $264 million discount associated with the 2.77% 2053 Notes are 
being accreted over the term of these newly issued notes and recorded as Interest expense, net, in the Consolidated Statements 
of Income.

Cross-currency swaps

To hedge our exposure to foreign currency exchange rate risk associated with certain of our long-term notes denominated 
in  foreign  currencies,  we  entered  into  cross-currency  swap  contracts.  The  terms  of  these  contracts  effectively  convert  the 
interest payments and principal repayments on our 0.41% 2023 Swiss franc Bonds, 2.00% 2026 euro Notes, 5.50% 2026 pound 
sterling Notes and 4.00% 2029 pound sterling Notes from euros, pounds sterling and Swiss francs to U.S. dollars. These cross-
currency swap contracts have been designated as cash flow hedges. For information regarding the terms of these contracts, see 
Note 18, Derivative instruments.

In  connection  with  the  redemption  of  the  1.25%  2022  euro  Notes,  discussed  above,  associated  cross-currency  swap 

contracts with an aggregate notional amount of €1.25 billion were terminated. 

Shelf registration statement and other facilities

As of December 31, 2022, we have a commercial paper program that allows us to issue up to $2.5 billion of unsecured 
commercial  paper  to  fund  our  working-capital  needs.  As  of  December  31,  2022  and  2021,  we  had  no  amounts  outstanding 
under our commercial paper program.

In 2019, we amended and restated our $2.5 billion syndicated, unsecured, revolving credit agreement, which is available 
for  general  corporate  purposes  or  as  a  liquidity  backstop  to  our  commercial  paper  program.  The  commitments  under  the 
revolving credit agreement may be increased by up to $750 million with the agreement of the banks. Each bank that is a party to 
the  agreement  has  an  initial  commitment  term  of  five  years.  This  term  may  be  extended  for  up  to  two  additional  one-year 
periods  with  the  agreement  of  the  banks.  Annual  commitment  fees  for  this  agreement  are  0.1%  of  the  unused  portion  of  the 
facility based on our current credit rating. In December 2022, this revolving credit agreement was further amended to replace 
LIBOR with SOFR as the reference rate, pursuant to provisions contained therein related to determination of successor rates in 
case  of  phaseout  or  unavailability  of  existing  designated  reference  rates.  Generally,  we  would  be  charged  interest  for  any 
amounts borrowed under this facility, based on our current credit rating, at (i) SOFR plus 1.125% or (ii) the highest of (A) the 
syndication agent bank base commercial lending rate, (B) the overnight federal funds rate plus 0.50% or (C) one-month SOFR 
plus 1.1%. As of December 31, 2022 and 2021, no amounts were outstanding under this facility.

In February 2020, we filed a shelf registration statement with the SEC that allows us to issue unspecified amounts of debt 
securities; common stock; preferred stock; warrants to purchase debt securities, common stock, preferred stock or depositary 
shares;  rights  to  purchase  common  stock  or  preferred  stock;  securities  purchase  contracts;  securities  purchase  units;  and 
depositary shares. Under this shelf registration statement, all of the securities available for issuance may be offered from time to 
time with terms to be determined at the time of issuance. This shelf registration statement expires in February 2023, and our 
Board has approved a new shelf registration statement to replace it.

In December 2022, in connection with the proposed acquisition of Horizon, we entered into a bridge credit agreement and 
a term loan credit agreement which provide for borrowings aggregating $28.5 billion. As of December 31, 2022, no amounts 
have been borrowed under either agreement. See Note 2, Acquisitions and divestitures.

Certain of our financing arrangements contain nonfinancial covenants. In addition, our revolving credit agreement, bridge 
credit  agreement  and  term  loan  agreement  include  a  financial  covenant,  which  requires  us  to  maintain  a  specified  minimum 
interest  coverage  ratio  of  (i)  the  sum  of  consolidated  net  income,  interest  expense,  provision  for  income  taxes,  depreciation 
expense,  amortization  expense,  unusual  or  nonrecurring  charges  and  other  noncash  items  (Consolidated  EBITDA)  to  (ii) 
Consolidated  Interest  Expense,  each  as  defined  and  described  in  the  respective  agreements.  We  were  in  compliance  with  all 
applicable covenants under these arrangements as of December 31, 2022.

Interest costs are expensed as incurred except to the extent such interest is related to construction in progress, in which 
case interest is capitalized. Interest costs capitalized for the years ended December 31, 2022, 2021 and 2020, were not material. 
Interest paid, including the ongoing impact of interest rate and cross-currency swap contracts, during each of the years ended 
December 31, 2022, 2021 and 2020, were $1.2 billion.

During  the  first  quarter  of  2022,  the  Company  entered  into  ASR  agreements  with  third-party  financial  institutions 
(Dealers) whereby the Company made payments in an aggregate amount of $6.0 billion to the Dealers and received and retired 
an initial 23.3 million shares of the Company’s common stock from the Dealers. The payments were recorded as reductions to 
shareholders’ equity, consisting of a $5.1 billion increase to accumulated deficit, which reflects the value of the initial shares 
received,  and  a  $0.9  billion  decrease  in  additional  paid-in  capital,  which  reflects  the  value  of  the  stock  that  remained  to  be 
delivered by the Dealers. During the third quarter of 2022, an additional 1.5 million shares of the Company’s common stock 
were received from the Dealers which constituted final settlement under the ASR agreements, and accordingly, the $0.9 billion 
decrease  in  additional  paid-in  capital  recorded  in  the  first  quarter  was  reclassified  to  accumulated  deficit.  In  total,  we 
repurchased 26.1 million shares of common stock during the year ended December 31, 2022, consisting primarily of the 24.8 
million shares received under the ASR agreements.

In  October  2022,  our  Board  of  Directors  increased  the  amount  authorized  under  our  stock  repurchase  program  by  an 

additional $2.4 billion. As of December 31, 2022, $7.0 billion remained available under our stock repurchase program. 

Dividends

Our Board of Directors declared quarterly dividends per share of $1.94, $1.76 and $1.60, which were paid in each of the 

four quarters of 2022, 2021 and 2020, respectively.

Historically, we have declared dividends in December of each year, which were paid in the first quarter of the following 
fiscal year and in March, July and October, which were paid in the second, third and fourth quarters, respectively, of the same 
fiscal year. Additionally, on December 12, 2022, the Board of Directors declared a quarterly cash dividend of $2.13 per share of 
common  stock,  which  will  be  paid  in  March  2023,  to  all  stockholders  of  record  as  of  the  close  of  business  on  February  15, 
2023.

17. Fair value measurement

To  estimate  the  fair  value  of  our  financial  assets  and  liabilities,  we  use  valuation  approaches  within  a  hierarchy  that 
maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be 
used when available. Observable inputs are inputs that market participants would use in pricing an asset or liability based on 
market  data  obtained  from  sources  independent  of  the  Company.  Unobservable  inputs  are  inputs  that  reflect  the  Company’s 
assumptions about the inputs that market participants would use in pricing an asset or liability and are developed based on the 
best  information  available  in  the  circumstances.  The  fair  value  hierarchy  is  divided  into  three  levels  based  on  the  source  of 
inputs as follows:

Level 1 — Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company 

has the ability to access

Level 2 — Valuations for which all significant inputs are observable either directly or indirectly—other than Level 1 inputs

Level 3 — Valuations based on inputs that are unobservable and significant to the overall fair value measurement

The availability of observable inputs can vary among the various types of financial assets and liabilities. To the extent that 
the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value 
requires more judgment. In certain cases, the inputs used for measuring fair value may fall into different levels of the fair value 
hierarchy. In such cases, for financial statement disclosure purposes, the level in the fair value hierarchy within which the fair 
value  measurement  is  categorized  is  based  on  the  lowest  level  of  input  used  that  is  significant  to  the  overall  fair  value 
measurement.

The fair values of each major class of the Company’s financial assets and liabilities measured at fair value on a recurring 

basis were as follows (in millions):

Interest-bearing and equity securities

The  fair  values  of  our  U.S.  Treasury  securities,  money  market  mutual  funds  and  equity  investments  in  publicly  traded 
securities  are  based  on  quoted  market  prices  in  active  markets,  with  no  valuation  adjustment.  Other  investments  consist  of 
interest-bearing deposits that are valued at amortized cost, which approximates fair value given their near term maturity. The 
fair  value  of  equity  securities  for  which  the  fair  value  option  was  elected  are  initially  valued  at  the  transaction  price  and 
subsequently valued based on a combination of observable price transactions, when available, market performance and publicly 
available  market  information  for  similar  companies  that  have  actively  traded  equity  securities.  See  Note  9,  Investments— 
Neumora Therapeutics, Inc.

Derivatives

Our  foreign  currency  forward  contracts,  cross-currency  swap  contracts  and  interest  rate  swap  contracts  are  with 
counterparties that have minimum credit ratings of A– or equivalent by S&P, Moody’s or Fitch. We estimate the fair values of 
these contracts by taking into consideration valuations obtained from a third-party valuation service that uses an income-based 
industry-standard valuation model for which all significant inputs are observable either directly or indirectly. These inputs, as 
applicable, include foreign currency exchange rates, LIBOR, swap rates, obligor credit default swap rates and cross-currency 
basis swap spreads. Certain inputs, when applicable, are at commonly quoted intervals. See Note 18, Derivative instruments.

Contingent consideration obligations

As a result of our business acquisitions, we have incurred contingent consideration obligations as discussed below. The 
contingent consideration obligations are recorded at their fair values by using probability-adjusted discounted cash flows, and 
we  revalue  these  obligations  each  reporting  period  until  the  related  contingencies  have  been  resolved.  The  fair  value 
measurements  of  these  obligations  are  based  on  significant  unobservable  inputs  related  to  licensing  rights  and  product 
candidates  acquired  in  business  combinations,  and  they  are  reviewed  quarterly  by  management  in  our  R&D  and  commercial 
sales  organizations.  The  inputs  include,  as  applicable,  estimated  probabilities  and  the  timing  of  achieving  specified 
development,  regulatory  and  commercial  milestones  as  well  as  estimated  annual  sales.  Significant  changes  to  these  inputs 
would  result  in  corresponding  increases  or  decreases  in  the  fair  values  of  the  obligations,  as  applicable.  Changes  in  the  fair 
values  of  contingent  consideration  obligations  are  recognized  in  Other  operating  expenses  in  the  Consolidated  Statements  of 
Income.

Changes in the carrying amounts of contingent consideration obligations were as follows (in millions):

As a result of our acquisition of Teneobio in 2021, we are obligated to pay its former shareholders up to $1.6 billion upon 
achieving separate development and regulatory milestones with regard to various R&D programs. See Note 2, Acquisitions and 
divestitures.

As a result of our acquisition of K-A in 2018, we are obligated to make single-digit royalty payments to Kirin Holdings 

Company, Limited contingent upon sales of brodalumab.

As  a  result  of  our  acquisition  of  BioVex  Group  Inc.  in  2011,  we  were  obligated  to  pay  its  former  shareholders  upon 
achieving separate sales-related milestones with regard to IMLYGIC if certain sales thresholds were met. During the year ended 
December 31, 2020, we determined that the likelihood of achieving these milestones was no longer probable, and accordingly, 
the obligations were written off.

Summary of the fair values of other financial instruments

Cash equivalents

The  fair  values  of  cash  equivalents  approximate  their  carrying  values  due  to  the  short-term  nature  of  such  financial 

instruments.

Borrowings

We  estimated  the  fair  values  of  our  borrowings  by  using  Level  2  inputs.  As  of  December  31,  2022  and  2021,  the 
aggregate fair values of our borrowings were $35.0 billion and $37.9 billion, respectively, and the carrying values were $38.9 
billion and $33.3 billion, respectively.

Investment in BeiGene

We estimated the fair value of our investment in BeiGene by using Level 1 inputs. As of December 31, 2022 and 2021, 

the fair values were $4.2 billion and $5.1 billion, and the carrying values were $2.2 billion and $2.8 billion, respectively.

F-43

 
 
 
 
 
 
During the years ended December 31, 2022 and 2021, there were no transfers of assets or liabilities between fair value 
measurement levels, and there were no material remeasurements to the fair values of assets and liabilities that are not measured 
at fair value on a recurring basis.

18. Derivative instruments

The Company is exposed to foreign currency exchange rate and interest rate risks related to its business operations. To 
reduce  our  risks  related  to  such  exposures,  we  use  or  have  used  certain  derivative  instruments,  including  foreign  currency 
forward,  foreign  currency  option,  cross-currency  swap,  forward  interest  rate  and  interest  rate  swap  contracts.  We  have 
designated certain of our derivatives as cash flow and fair value hedges; we also have derivatives not designated as hedges. We 
do not use derivatives for speculative trading purposes.

Cash flow hedges

We  are  exposed  to  possible  changes  in  the  values  of  certain  anticipated  foreign  currency  cash  flows  resulting  from 
changes  in  foreign  currency  exchange  rates  primarily  associated  with  our  euro-denominated  international  product  sales.  The 
foreign  currency  exchange  rate  fluctuation  exposure  associated  with  cash  inflows  from  our  international  product  sales  are 
partially offset by corresponding cash outflows from our international operating expenses. To further reduce this exposure, we 
enter into foreign currency forward contracts to hedge a portion of our projected international product sales up to a maximum of 
three years into the future; and at any given point in time, a higher percentage of nearer-term projected product sales is being 
hedged than in successive periods.

As of December 31, 2022, 2021 and 2020, we had outstanding foreign currency forward contracts with aggregate notional 
amounts  of  $6.0  billion,  $5.7  billion  and  $5.1  billion,  respectively.  We  have  designated  these  foreign  currency  forward 
contracts,  which  are  primarily  euro  based,  as  cash  flow  hedges.  Accordingly,  we  report  unrealized  gains  and  losses  on  these 
contracts in AOCI in the Consolidated Balance Sheets, and we reclassify them to Product sales in the Consolidated Statements 
of Income in the same periods during which the hedged transactions affect earnings.

To hedge our exposure to foreign currency exchange rate risk associated with certain of our long-term debt denominated 
in foreign currencies, we enter into cross-currency swap contracts. Under the terms of such contracts, we paid euros, pounds 
sterling and Swiss francs and received U.S. dollars for the notional amounts at inception of the contracts; and based on these 
notional  amounts,  we  exchange  interest  payments  at  fixed  rates  over  the  lives  of  the  contracts  by  paying  U.S.  dollars  and 
receiving euros, pounds sterling and Swiss francs. In addition, we will pay U.S. dollars to and receive euros, pounds sterling 
and Swiss francs from the counterparties at the maturities of the contracts for these same notional amounts. The terms of these 
contracts correspond to the related hedged debt, thereby effectively converting the interest payments and principal repayment 
on  the  debt  from  euros,  pounds  sterling  and  Swiss  francs  to  U.S.  dollars.  We  have  designated  these  cross-currency  swap 
contracts  as  cash  flow  hedges.  Accordingly,  the  unrealized  gains  and  losses  on  these  contracts  are  reported  in  AOCI  in  the 
Consolidated Balance Sheets and reclassified to Other (expense) income, net, in the Consolidated Statements of Income in the 
same periods during which the hedged debt affects earnings.

 The notional amounts and interest rates of our cross-currency swaps as of December 31, 2022, were as follows (notional 

amounts in millions):

0.41% 2023 Swiss franc Bonds

In connection with the anticipated issuance of long-term fixed-rate debt, we occasionally enter into forward interest rate 
contracts in order to hedge the variability in cash flows due to changes in the applicable U.S. Treasury rate between the time we 
enter into these contracts and the time the related debt is issued. Gains and losses on forward interest rate contracts, which are 
designated  as  cash  flow  hedges,  are  recognized  in  AOCI  in  the  Consolidated  Balance  Sheets  and  are  amortized  into  Interest 
expense, net, in the Consolidated Statements of Income over the lives of the associated debt issuances. In December 2022, we 
entered  into  a  forward  interest  rate  contract  with  an  aggregate  notional  amount  of  $700  million.  Amounts  expected  to  be 
recognized during the subsequent 12 months on forward interest rate contracts are not material.

To achieve a desired mix of fixed-rate and floating-rate debt, we entered into interest rate swap contracts that qualified for 
and were designated as fair value hedges. These interest rate swap contracts effectively convert fixed-rate coupons to floating-
rate  LIBOR-based  coupons  over  the  terms  of  the  related  hedge  contracts.  As  of  both  December  31,  2022  and  2021,  we  had 
interest rate swap contracts with aggregate notional amounts of $6.7 billion that hedge certain portions of our long-term debt 
issuances. See Note 15, Financing arrangements, for information on our interest rate swaps.

For interest rate swap contracts that qualify for and are designated as fair value hedges, we recognize in Interest expense, 
net, in the Consolidated Statements of Income the unrealized gain or loss on the derivative resulting from the change in fair 
value during the period, as well as the offsetting unrealized loss or gain of the hedged item resulting from the change in fair 
value  during  the  period  attributable  to  the  hedged  risk.  If  a  hedging  relationship  involving  an  interest  rate  swap  contract  is 
terminated, the gain or loss realized on contract termination is recorded as an adjustment to the carrying value of the debt and 
amortized into Interest expense, net, over the remaining life of the previously hedged debt.

The hedged liabilities and related cumulative-basis adjustments for fair value hedges of those liabilities were recorded in 

the Consolidated Balance Sheets as follows (in millions):

Derivatives not designated as hedges

To reduce our exposure to foreign currency fluctuations in certain assets and liabilities denominated in foreign currencies, 
we enter into foreign currency forward contracts that are not designated as hedging transactions. Most of these exposures are 
hedged  on  a  month-to-month  basis.  As  of  December  31,  2022,  2021  and  2020,  the  total  notional  amounts  of  these  foreign 
currency  forward  contracts  were  $517  million,  $680  million  and  $1.0  billion,  respectively.  Gains  and  losses  recognized  in 
earnings for our derivative instruments not designated as hedging instruments were not material for the years ended December 
31, 2022, 2021 and 2020.

Our  derivative  contracts  that  were  in  liability  positions  as  of  December  31,  2022,  contain  certain  credit-risk-related 
contingent provisions that would be triggered if (i) we were to undergo a change-in-control and (ii) our or the surviving entity’s 
creditworthiness  deteriorates,  which  is  generally  defined  as  having  either  a  credit  rating  that  is  below  investment  grade  or  a 
materially weaker creditworthiness after the change-in-control. If these events were to occur, the counterparties would have the 
right, but not the obligation, to close the contracts under early-termination provisions. In such circumstances, the counterparties 
could request immediate settlement of these contracts for amounts that approximate the then current fair values of the contracts. 
In  addition,  our  derivative  contracts  are  not  subject  to  any  type  of  master  netting  arrangement,  and  amounts  due  either  to  or 
from a counterparty under the contracts may be offset against other amounts due either to or from the same counterparty only if 
an event of default or termination, as defined, were to occur.

The cash flow effects of our derivative contracts in the Consolidated Statements of Cash Flows are included in Net cash 
provided by operating activities, except for the settlement of notional amounts of cross-currency swaps, which are included in 
Net cash used in financing activities.

19. Contingencies and commitments 

Contingencies

In  the  ordinary  course  of  business,  we  are  involved  in  various  legal  proceedings,  government  investigations  and  other 
matters  that  are  complex  in  nature  and  have  outcomes  that  are  difficult  to  predict.  See  Part  I,  Item  1A.  Risk  Factors—Our 
business may be affected by litigation and government investigations. We describe our legal proceedings and other matters that 
are significant or that we believe could become significant in this footnote.

We record accruals for loss contingencies to the extent that we conclude it is probable that a liability has been incurred 
and  the  amount  of  the  related  loss  can  be  reasonably  estimated.  We  evaluate,  on  a  quarterly  basis,  developments  in  legal 
proceedings  and  other  matters  that  could  cause  an  increase  or  decrease  in  the  amount  of  the  liability  that  has  been  accrued 
previously.

Our legal proceedings involve various aspects of our business and a variety of claims, some of which present novel factual 
allegations and/or unique legal theories. In each of the matters described in this filing, in which we could incur a liability, our 
opponents seek an award of a not-yet-quantified amount of damages or an amount that is not material. In addition, a number of 
the matters pending against us are at very early stages of the legal process, which in complex proceedings of the sort we face 
often extend for several years. As a result, none of the matters described in this filing, in which we could incur a liability, have 
progressed sufficiently through discovery and/or the development of important factual information and legal issues to enable us 
to estimate a range of possible loss, if any, or such amounts are not material. While it is not possible to accurately predict or 
determine the eventual outcomes of these matters, an adverse determination in one or more of these matters currently pending 
could have a material adverse effect on our consolidated results of operations, financial position or cash flows.

Certain recent developments concerning our legal proceedings and other matters are discussed below:

ANDA Patent Litigation

Otezla ANDA Patent Litigation

Amgen Inc. v. Sandoz Inc., et al.

Beginning in June 2018, Celgene filed 19 separate lawsuits in the U.S. District Court for the District of New Jersey (the 
New Jersey District Court) against Alkem Laboratories Ltd. (Alkem); Amneal Pharmaceuticals LLC (Amneal); Annora Pharma 
Private  Ltd.  and  Hetero  USA  Inc.  (collectively,  Hetero);  Aurobindo  Pharma  Ltd.  and  Aurobindo  Pharma  USA  Inc. 
(collectively,  Aurobindo);  Cipla  Limited  (Cipla  Ltd);  DRL;  Emcure  Pharmaceuticals  Ltd.  and  Heritage  Pharmaceuticals  Inc. 
(collectively,  Emcure);  Glenmark  Pharmaceuticals  Ltd.  (Glenmark);  Macleods  Pharmaceuticals  Ltd.  (Macleods);  Mankind 
Pharma  Ltd.  (Mankind);  MSN  Laboratories  Private  Limited  (MSN);  Pharmascience  Inc.  (Pharmascience);  Prinston 
Pharmaceutical  Inc.  (Prinston);  Sandoz  Inc.  (Sandoz);  Shilpa  Medicare  Ltd.  (Shilpa);  Teva  Pharmaceuticals  USA,  Inc.  and 
Actavis  LLC  (collectively,  Actavis);  Torrent  Pharmaceuticals  Ltd.  (Torrent);  Unichem  Laboratories,  Ltd.  (Unichem);  and 
Zydus Pharmaceuticals (USA) Inc. (Zydus), each for infringement of one or more of the following patents: U.S. Patent Nos. 
6,962,940 (the ’940 Patent), 7,208,516 (the ’516 Patent), 7,427,638 (the ’638 Patent), 7,659,302 (the ’302 Patent), 7,893,101 
(the ’101 Patent), 8,455,536 (the ’536 Patent), 8,802,717 (the ’717 Patent), 9,018,243 (the ’243 Patent) and 9,872,854 (the ’854 
Patent), which are listed in the Orange Book for Otezla. Each of these lawsuits was based on each defendant’s submission of an 
ANDA  seeking  FDA  approval  to  market  a  generic  version  of  Otezla.  The  New  Jersey  District  Court  consolidated  these  19 
lawsuits for discovery and case management purposes into a single case, Celgene Corp. v. Sandoz Inc., et al. Each lawsuit seeks 
an order of the New Jersey District Court making any FDA approval of the respective defendant’s ANDA effective no earlier 
than the expiration of the applicable patents.

In  August  2018,  Celgene  filed  amended  complaints  against  Alkem,  Amneal,  Aurobindo,  Cipla  Ltd,  DRL,  Glenmark, 
Pharmascience, Sandoz, Actavis, Unichem and Zydus additionally asserting U.S. Patent No. 9,724,330 (the ’330 Patent), which 
is  listed  in  the  Orange  Book  for  Otezla.  Between  October  15  and  November  27,  2018,  Celgene  filed  amended  complaints 
against Alkem, Amneal, Hetero, Aurobindo, Cipla Ltd, DRL, Emcure, Glenmark, Macleods, Mankind, MSN, Pharmascience, 
Prinston,  Sandoz,  Actavis,  Torrent,  Unichem  and  Zydus  additionally  asserting  U.S.  Patent  No.  10,092,541  (the  ’541  Patent), 
which is listed in the Orange Book for Otezla. Between March 1 and April 4, 2019, Celgene filed amended complaints against 
Hetero, MSN and Emcure for infringement of one or more of the above-listed patents. On October 1, 2019, Celgene filed an 
amended  complaint  against  Mankind  for  infringement  of  the  ’940,  ’302,  ’536,  ’243  and  ’330  Patents.  On  October  8,  2019, 
Celgene filed a separate lawsuit against Zydus in the New Jersey District Court for infringement of U.S. Patent Nos. 8,093,283 
(the ’283 Patent) and 8,629,173, which are not listed in the Orange Book for Otezla. On December 19, 2019, the New Jersey 
District  Court  consolidated  this  lawsuit  for  discovery  and  case  management  purposes  into  the  existing  consolidated  case, 
Celgene Corp. v. Sandoz Inc., et al. Each defendant has filed an answer to the above-listed complaints and amended complaints 
disputing infringement and/or validity of the patents asserted against it. Along with their answers, each of Alkem, Hetero, Cipla 
Ltd, DRL, Emcure, Glenmark, Macleods, Mankind, Pharmascience, Sandoz, Shilpa, Actavis, Torrent, Unichem and Zydus filed 
declaratory  judgment  counterclaims  asserting  that  some  or  all  of  the  patents  are  not  infringed  and/or  are  invalid.  In  August 
2019,  based  on  a  joint  request  by  Celgene  and  Glenmark,  the  New  Jersey  District  Court  entered  a  consent  judgment  and 
injunction  prohibiting  the  making,  having  made,  using,  selling,  offering  to  sell,  importing,  or  distributing  of  Glenmark’s 
apremilast product during the term of the ’940, ’638, ’302, ’101, ’536, ’243, ’330 and ’541 Patents, unless authorized pursuant 
to a confidential settlement agreement. 

Following Amgen’s acquisition of the patents-in-suit and the new drug application for Otezla, on February 14, 2020, the 
New Jersey District Court issued an order substituting Amgen for Celgene as plaintiff in the consolidated action and all related 
actions, terminating Celgene as plaintiff in the consolidated action and all related actions, and amending the case caption in the 
consolidated action and all related actions to reflect Amgen as the sole plaintiff.

On March 25, 2020, based on a joint request by Amgen and Unichem, the New Jersey District Court entered a consent 
judgment and injunction prohibiting the making, using, selling, offering to sell, or importing of Unichem’s apremilast product

product during the term of the ’940, ’516, ’638, ’302, ’101, ’536, ’717, ’243, ’330, ’854 and ’541 Patents, unless authorized 
pursuant to a confidential settlement agreement. On May 28, 2020, based on a joint request by Amgen and Emcure, the New 
Jersey  District  Court  entered  a  consent  judgment  and  injunction  prohibiting  the  making,  using,  selling,  offering  to  sell,  or 
importing of Emcure’s apremilast product during the term of the ’638, ’101, ’854 and ’541 Patents unless authorized pursuant 
to a confidential settlement agreement. On July 7, 2020, the New Jersey District Court ordered a stipulated dismissal without 
prejudice of all claims, counterclaims, and affirmative defenses between Amgen and Sandoz with respect to the ’717, ’516 and 
’854 Patents, leaving the ’940, ’302, ’536, ’243, ’330, ’638, ’101 and ’541 Patents asserted by Amgen against Sandoz in the 
litigation. On August 6, 2020, based on a joint request by Amgen and Mankind, the New Jersey District Court entered a consent 
judgment and injunction prohibiting the making, using, selling, offering to sell, or importing of Mankind’s apremilast product 
during the term of the ’940, ’302, ’536, ’243, ’330, ’638, ’101 and ’541 Patents, unless authorized pursuant to a confidential 
settlement agreement. On August 14, 2020, based on a joint request by Amgen and Macleods, the New Jersey District Court 
entered a consent judgment and injunction prohibiting the making, using, selling, offering to sell, or importing of Macleods’ 
apremilast  product  during  the  term  of  the  ’638  and  ’541  Patents,  unless  authorized  pursuant  to  a  confidential  settlement 
agreement.  On  October  7,  2020,  based  on  a  joint  request  by  Amgen  and  Amneal,  the  New  Jersey  District  Court  entered  a 
consent judgment and injunction prohibiting the making, using, selling, offering to sell, or importing of Amneal’s apremilast 
product  during  the  term  of  the  ’101,  ’940,  ’638,  ’302,  ’536,  ’243,  ’330  and  ’541  Patents,  unless  authorized  pursuant  to  a 
confidential  settlement  agreement.  On  December  30,  2020,  based  on  a  joint  request  by  Amgen  and  Shilpa,  the  New  Jersey 
District Court entered a consent judgment and injunction prohibiting the making, using, selling, offering to sell, or importing of 
Shilpa’s  apremilast  product  during  the  term  of  the  ’638,  ’101  and  ’854  Patents,  unless  authorized  pursuant  to  a  confidential 
settlement  agreement.  On  January  26,  2021,  based  on  a  joint  request  by  Amgen  and  Actavis,  the  New  Jersey  District  Court 
entered  a  consent  judgment  and  injunction  prohibiting  the  making,  using,  selling,  offering  to  sell,  or  importing  of  Actavis’ 
apremilast  product  during  the  term  of  the  ’940,  ’516,  ’638,  ’302,  ’536,  ’717,  ’330,  ’854  and  ’541  Patents,  unless  authorized 
pursuant to a confidential settlement agreement. On March 24, 2021, based on a joint request by Amgen and Prinston, the New 
Jersey  District  Court  entered  a  consent  judgment  and  injunction  prohibiting  the  making,  using,  selling,  offering  to  sell,  or 
importing  of  Prinston’s  apremilast  product  during  the  term  of  the  ’638  and  ’541  Patents,  unless  authorized  pursuant  to  a 
confidential  settlement  agreement.  On  April  6,  2021,  based  on  a  joint  request  by  Amgen  and  Aurobindo,  the  New  Jersey 
District Court entered a consent judgment and injunction prohibiting the making, using, selling, offering to sell, or importing of 
Aurobindo’s  apremilast  product  during  the  term  of  the  ’940,  ’516,  ’638,  ’302,  ’101,  ’536,  ’717,  ’243,  ’330,  ’854  and  ’541

Trial on the consolidated patent infringement action against Sandoz and Zydus was held at the New Jersey District Court 

from June 14 to 25, 2021, with closing arguments on July 28, 2021. 

On September 28, 2021, consistent with its September 20, 2021 opinion and order, the New Jersey District Court entered 
final  judgment  in  favor  of  Amgen  and  against  Zydus  with  respect  to  claims  3  and  6  of  the  ’638  Patent,  claim  6  of  the  ’536 
Patent and claims 2 and 27 of the ’283 Patent; and final judgment in favor of Zydus and against Amgen with respect to claims 1 
and 15 of the ’101 Patent and claims 2, 19 and 21 of the ’541 Patent. The final judgment ordered that the effective date of any 
final approval by the FDA of Zydus’s ANDA must be after expiration of the three infringed patents (the ’638, ’536 and ’283 
Patents) and any regulatory exclusivity to which Amgen may become entitled. The final judgment also includes an injunction 
prohibiting  Zydus  from  making,  using,  offering  to  sell,  or  selling  in  the  United  States,  or  importing  into  the  United  States, 
Zydus’s generic apremilast products during the term of the three infringed patents. On October 27, 2021, Zydus filed a notice of 
appeal to the Federal Circuit Court with respect to the ’638 Patent. On October 28, 2021, Amgen filed a notice of appeal to the 
Federal Circuit Court.

On October 12, 2021, the New Jersey District Court also entered final judgment in favor of Amgen and against Sandoz 
with respect to claims 3 and 6 of the ’638 Patent, claim 6 of the ’536 Patent and claims 1 and 15 of the ’101 Patent; and final 
judgment in favor of Sandoz and against Amgen with respect to claims 2, 19 and 21 of the ’541 Patent. The final judgment 
ordered  that  the  effective  date  of  any  final  approval  by  the  FDA  of  Sandoz’s  ANDA  must  be  after  expiration  of  the  three 
infringed patents (the ’638, ’536 and ’101 Patents) and any regulatory exclusivity to which Amgen may become entitled. The 
final  judgment  also  includes  an  injunction  prohibiting  Sandoz  from  making,  using,  offering  to  sell,  or  selling  in  the  United 
States, or importing into the United States, Sandoz’s generic apremilast products during the term of the three infringed patents. 
On November 9, 2021, Sandoz filed a notice of appeal to the Federal Circuit Court with respect to the ’638 and ’101 Patents. 
On November 10, 2021, Amgen filed a notice of appeal to the Federal Circuit Court.

Oral argument for Amgen’s, Sandoz’s and Zydus’ appeals was held on February 8, 2023.

Amgen Inc. v. Apotex Inc.

On June 14, 2022, Amgen filed a lawsuit in the New Jersey District Court against Apotex Inc. (Apotex) for infringement 
of the ’638 Patent, the ’854 Patent and the ’541 Patent. This lawsuit was based on Apotex’s submission of an ANDA seeking 
FDA  approval  to  market  a  generic  version  of  Otezla  and  seeks  an  order  of  the  New  Jersey  District  Court  making  any  FDA 
approval of Apotex’s ANDA effective no earlier than the expiration of the applicable patents.

On October 14, 2022, Apotex filed its answer, disputing infringement and/or validity of the patents-in-suit. Along with its 
answer,  Apotex  also  filed  declaratory  judgment  counterclaims  asserting  that  the  patents-in-suit  are  not  infringed  and/or  are 
invalid. 

On January 20, 2023, based on a joint request by Amgen and Apotex, the New Jersey District Court entered a consent 
judgment  and  injunction  prohibiting  the  making,  using,  selling,  offering  to  sell,  or  importing  of  Apotex’s  apremilast  product 
during the term of the ’638, ’854, and ’541 Patents, unless authorized pursuant to a confidential settlement agreement.

Repatha Patent Litigation

Amgen Inc., et al. v. Sanofi, et al. 

In October 2014, Amgen initiated a series of lawsuits that were consolidated by the U.S. District Court for the District of 
Delaware  (Delaware  District  Court)  in  December  2014  into  a  single  case  against  Sanofi,  Sanofi-Aventis  U.S.  LLC  and 
Aventisub  LLC,  formerly  doing  business  as  Aventis  Pharmaceuticals  Inc.  (collectively,  Sanofi)  and  Regeneron 
Pharmaceuticals, Inc. (Regeneron), addressing seven of our patents: U.S. Patent Nos. 8,563,698; 8,829,165 (the ’165 Patent); 
8,859,741  (the  ’741  Patent);  8,871,913;  8,871,914;  8,883,983;  and  8,889,834.  These  patents  describe  and  claim  monoclonal 
antibodies  to  PCSK9.  By  its  complaints,  Amgen  seeks  an  injunction  to  prevent  the  infringing  manufacture,  use  and  sale  of 
Sanofi  and  Regeneron’s  alirocumab,  a  monoclonal  antibody  targeting  PCSK9.  In  January  2016,  the  Delaware  District  Court 
granted Amgen’s motion to amend the complaint to add its affiliates, Amgen Manufacturing, Limited and Amgen USA Inc., as 
plaintiffs and to add the allegation that Sanofi and Regeneron’s infringement of Amgen’s patents is willful.

In  February  2016,  the  Delaware  District  Court  entered  a  stipulated  order  finding  alirocumab  and  the  drug  product 
containing it, PRALUENT infringe certain of Amgen’s patents, including claims 2, 7, 9, 15, 19 and 29 of the ’165 Patent and 
claim 7 of the ’741 Patent. In March 2016, the Delaware District Court entered judgment in favor of Amgen following a five-
day jury trial and a unanimous jury verdict that these patent claims are all valid. In January 2017, the Delaware District Court 
denied Sanofi and Regeneron’s posttrial motions seeking a new trial and for judgment as a matter of law, and granted Amgen’s 
motion for a permanent injunction prohibiting the infringing manufacture, use, sale, offer for sale or import of alirocumab in the 
United States. Sanofi and Regeneron filed an appeal of the judgment and the permanent injunction to the Federal Circuit Court. 
In  February  2017,  following  a  motion  by  Sanofi  and  Regeneron,  the  Federal  Circuit  Court  entered  a  stay  of  the  permanent 
injunction during the pendency of the appeal. In October 2017, the Federal Circuit Court reversed in part the judgment of the 
Delaware  District  Court  and  remanded  for  a  new  trial  two  of  the  patent  validity  defenses  (lack  of  written  description  and 
enablement of the claimed inventions), and affirmed the Delaware District Court’s judgment of infringement of claims 2, 7, 9, 
15, 19 and 29 of the ’165 Patent and claim 7 of the ’741 Patent and the third patent validity defense (finding that the claimed 
inventions were not obvious to a person of ordinary skill in the field of the patents).

In March 2018, the Federal Circuit Court issued a mandate returning the case to the Delaware District Court for a new 
trial on two of Sanofi and Regeneron’s challenges to the validity of our patents (lack of written description and enablement of 
the  claimed  inventions)  and  for  further  consideration  of  a  permanent  injunction.  In  July  2018,  Amgen  filed  a  petition  for 
certiorari with the U.S. Supreme Court seeking review of the Federal Circuit Court’s conclusion that the judgment affirming the 
validity of Amgen’s patents was based, in part, on an erroneous application of the law of written description. On January 7, 
2019, the U.S. Supreme Court denied Amgen’s petition for certiorari. On remand, the Delaware District Court scheduled a new 
trial on Sanofi and Regeneron’s challenges to the validity of our patents based on lack of written description and enablement of 
the  claimed  inventions.  The  Delaware  District  Court  also  entered  judgment  on  the  pleadings  for  Sanofi  and  Regeneron  on 
Amgen’s claim of willful infringement.

On February 25, 2019, a jury of the Delaware District Court again unanimously upheld the validity of claims 19 and 29 of 
the ’165 Patent and claim 7 of the ’741 Patent. The jury also found that claims 7 and 15 of the ’165 Patent meet the enablement 
requirement, but are invalid for failure to meet the written description requirement. On March 18, 2019, Sanofi and Regeneron 
filed  posttrial  motions  seeking  to  reverse  the  jury  verdict  against  them  or  for  a  new  trial,  and  Amgen  filed  a  motion  for  a 
permanent  injunction.  On  August  28,  2019,  the  Delaware  District  Court  ruled  on  the  posttrial  motions,  denying  Sanofi  and 
Regeneron’s request for a new trial and their request to reverse the jury verdict that the ’165 Patent and the ’741 Patent provide 
written description support for the claimed inventions. The Delaware District Court also ruled as a matter of law that claims 19 
and 29 of the ’165 Patent and claim 7 of the ’741 Patent are invalid for failing to meet the enablement requirement, overturning 
the jury verdict. 

On October 23, 2019, Amgen filed a notice of appeal to the Federal Circuit Court and based on the subsequent hearing, on 
February 11, 2021 the Federal Circuit Court issued a decision affirming the Delaware District Court’s ruling. Amgen filed a 
petition for rehearing en banc which was denied on June 21, 2021. On November 18, 2021, Amgen filed a petition for writ of 
certiorari with the U.S. Supreme Court seeking review of the invalidation of claims 19 and 29 of the ’165 Patent and claim 7 of 
the ’741 Patent as lacking an enabling disclosure of the invention. 

On  November  4,  2022,  the  U.S.  Supreme  Court  granted  review  on  Amgen’s  petition  for  certiorari  on  the  question  of 
whether the appropriate standard was applied by the lower courts in invalidating claims 19 and 29 of the ’165 Patent and claim 
7 of the ’741 Patent as lacking an enabling disclosure of the invention. Amgen filed its opening brief on December 27, 2022. 
On  February  3,  2023,  Sanofi  and  Regeneron  filed  a  brief  in  response.  Oral  argument  before  the  U.S.  Supreme  Court  is 
scheduled for March 27, 2023.

Patent Disputes in the International Region

We  are  involved  in  and  expect  future  involvement  in  additional  disputes  regarding  our  PCSK9  patents  in  other 

jurisdictions and regions. This includes matters filed against us and that we have filed in Germany, Spain and Japan. 

In February 2016, the European Patent Office (EPO) granted European Patent No. 2,215,124 (EP 2,215,124) to Amgen. 
This patent describes and claims monoclonal antibodies to PCSK9 and methods of treatment and Sanofi filed an opposition to 
the patent in the EPO seeking to invalidate it. In November 2016, Sanofi-Aventis Deutschland GmbH, Sanofi-Aventis Groupe 
S.A.  and  Sanofi  Winthrop  Industrie  S.A.  filed  a  joint  opposition  against  Amgen’s  patent,  and  each  of  Lilly,  Regeneron  and 
Strawman Ltd. also filed oppositions to Amgen’s patent. In November 2018, the EPO confirmed the validity of Amgen’s EP 
2,215,124, which was appealed to the Technical Board of Appeal (TBA). On October 29, 2020, the TBA upheld the validity of 
certain claims, including claims that protect Repatha, but ruled that broader claims encompassing PRALUENT were invalid. As 
a result of the TBA’s decision, national litigations regarding PRALUENT in Europe are in the process of being resolved. In 
Germany, Sanofi-Aventis Deutschland GmbH and Regeneron have filed actions seeking damages arising from the provisional 
enforcement of an injunction against PRALUENT that was lifted after the TBA’s October 29, 2020 ruling.

On  March  23,  2022,  Amgen  filed  counterclaims  alleging  that  PRALUENT  infringes  Amgen’s  European  Patent  No. 
2,641,917  (the  ’917  Patent).  A  EPO  opposition  to  the  ’917  Patent,  filed  by  Sanofi  on  February  5,  2021,  is  pending,  and  the 
hearing before the EPO’s Opposition Division is scheduled for February 21, 2023.

On July 21, 2022, Sanofi Biotechnology SAS filed an action against Amgen GmbH and Amgen (Europe) B.V. before the 
Regional  Court  of  Dusseldorf  alleging  that  the  marketing  and  sale  of  Repatha  infringes  European  Patent  No.  2,756,004  (the 
EP’004 Patent), seeking infringement damages and injunctive relief. The EP’004 Patent is currently in opposition proceedings, 
initiated by Amgen and an anonymous third party, before the EPO. A hearing before the Opposition Division of the EPO was 
held on June 8 and 9, 2022, and on August 16, 2022, the Opposition Division issued a written decision upholding the validity of 
the EP’004 Patent claims at issue, with narrowing amendments. Proceedings before the TBA commenced on August 17, 2022. 
On November 22, 2022, Amgen filed Grounds of Appeal before the TBA, and on December 30, 2022, Regeneron filed Grounds 
of  Appeal  before  the  TBA.  On  January  23,  2023,  the  TBA  invited  Amgen  to  file  any  response  to  Regeneron’s  Grounds  of 
Appeal by May 23, 2023.

On April 24, 2020, the Supreme Court of Japan declined to hear Sanofi K.K.’s appeals making final the Japanese High 
Court’s  decisions  that  PRALUENT  infringes  Amgen’s  valid  patent  rights  in  Japan.  On  June  24,  2020,  Amgen  filed  written 
answers to the invalidity trials initiated by Regeneron on February 12, 2020 before the Japan Patent Office seeking to invalidate 
Amgen’s Japanese patents that were previously held infringed by PRALUENT and valid over challenges filed by Sanofi K.K. 
On April 15, 2021, the Japanese Patent Office dismissed Regeneron’s invalidity trials, and in August 2021 Regeneron appealed 
the decisions to the Japanese High Court. On January 26, 2023, the Japanese High Court found Amgen’s patent claims invalid 
for lacking adequate support. The decision is subject to appeal to the Japanese Supreme Court. Damages proceedings against 
Sanofi K.K. are ongoing before the Tokyo District Court, where Sanofi K.K. has initiated new validity challenges to Amgen 
patents in Japan. 

ABP 654 (ustekinumab) Patent Litigation

Janssen Biotech, Inc. v. Amgen Inc. 

On  November  29,  2022,  Janssen  filed  a  lawsuit  in  the  Delaware  District  Court  alleging  Amgen’s  infringement  of  two 
patents  by  Amgen’s  submission  of  an  application  for  FDA  licensure  of  ABP  654,  Amgen’s  biosimilar  version  of  Janssen’s 
STELARA (ustekinumab) and also seeking declaratory judgment of infringement of the same two patents.

Antitrust Class Action

Sensipar Antitrust Class Actions

From  February  to  April  2019,  four  plaintiffs  filed  putative  class  action  lawsuits  against  Amgen  and  various  entities 
affiliated with Teva Pharmaceuticals USA, Inc. (Teva) alleging anticompetitive conduct in connection with settlements between 
Amgen  and  manufacturers  of  generic  cinacalcet  product.  two  of  those  actions  were  brought  in  the  Delaware  District  Court, 
captioned UFCW Local 1500 Welfare Fund v. Amgen Inc., et al. (February 21, 2019) (Local 1500) and Cesar Castillo, Inc. v. 
Amgen  Inc.,  et  al.  (February  26,  2019)  (Castillo).  The  third  action  was  brought  in  the  New  Jersey  District  Court,  captioned 
Teamsters Local 237 Welfare Fund, et al. v. Amgen Inc., et al. (March 14, 2019) (Local 237) and the fourth action was brought 
in  the  U.S.  District  Court  for  the  Eastern  District  of  Pennsylvania  (the  Eastern  Pennsylvania  District  Court),  captioned  KPH 
Healthcare Services, Inc. a/k/a Kinney Drugs, Inc. v. Amgen Inc., et al (April 10, 2019) (KPH). Each of the lawsuits is brought 
on behalf of a putative class of direct or indirect purchasers of Sensipar and alleges that the plaintiffs have overpaid for Sensipar 
as a result of Amgen’s conduct that allegedly improperly delayed market entry by manufacturers of generic cinacalcet products. 

F-52

The  lawsuits  focus  predominantly  on  the  settlement  among  Amgen,  Watson  Laboratories,  Inc.  (Watson)  and  Teva  of  the 
parties’  patent  infringement  litigation.  Each  of  the  lawsuits  seeks,  among  other  things,  treble  damages,  equitable  relief  and 
attorneys’ fees and costs. On April 10, 2019, the plaintiff in the KPH lawsuit filed a motion seeking to have the four lawsuits 
consolidated and designated as a multidistrict litigation (MDL) in the Eastern Pennsylvania District Court, and the plaintiff in 
the Local 1500 lawsuit filed a motion seeking to have the four lawsuits, along with Cipla Ltd. v. Amgen Inc., consolidated and 
designated as an MDL in the Delaware District Court. 

On  July  31,  2019,  the  MDL  panel  entered  an  order  consolidating  in  the  Delaware  District  Court  the  four  class  action 
lawsuits. On September 13, 2019, the plaintiffs filed amended complaints, and on October 15, 2019, Amgen filed its motion to 
dismiss both the direct purchaser plaintiffs’ consolidated class action complaint and the indirect purchaser end payer plaintiffs’ 
complaint.  On  December  6,  2019,  the  plaintiffs  responded  to  Amgen’s  motion  to  dismiss  and,  on  January  10,  2020,  Amgen 
filed its response. On February 6, 2020, the motions in the class action lawsuits were transferred to the U.S. Magistrate Judge 
for the District of Delaware (Magistrate Judge) for a recommendation. The MDL panel certified its conditional transfer order on 
February 6, 2020 transferring the additional class action lawsuit brought in the U.S. District Court for the Southern District of 
Florida, captioned MSP Recovery Claims v. Amgen Inc., et al., to the Delaware District Court.

 On July 22, 2020, the Magistrate Judge issued a recommendation to the Delaware District Court that the claims against 
Amgen  be  dismissed  but  leave  be  given  to  plaintiffs  to  amend  their  complaints.  On  August  5,  2020,  the  plaintiffs  filed 
objections to the Magistrate Judge’s report and recommendation. On August 19, 2020, Amgen filed a response to the plaintiffs’ 
objections. On November 30, 2020, the District Court adopted the Magistrate Judge’s recommendation in part and denied it in 
part, denying Amgen’s motion to dismiss on the grounds that plaintiffs adequately alleged reverse payment claims but granted 
Amgen’s  motion  to  dismiss  with  respect  to  the  other  Federal  antitrust  claims.  On  December  23,  2020,  Teva,  Watson  and 
Actavis filed a motion for interlocutory appeal and for a stay pending appeal and Amgen filed its joinder (the 1292 Motion). On 
January  5,  2021,  a  joint  status  report  was  filed  advising  the  Delaware  District  Court  that  the  defendants  are  still  considering 
whether to withdraw the 1292 Motion and plaintiffs’ offer to stay discovery, pending further rulings on motions to dismiss the 
amended complaints. On January 19, 2021, a joint status report was filed pursuant to the Delaware District Court’s January 6, 
2021 order along with a stipulation to defer the 1292 Motion until after rulings on the amended complaints.

On February 16, 2021, the plaintiffs in the antitrust class action lawsuit brought on behalf of putative classes of direct or 
indirect purchasers of Sensipar filed their amended complaints. On March 4, 2021, a stipulation and order regarding the filing 
of a second amended complaint were filed to add another plaintiff: Teamsters Western Region & Local 177 Health Care Fund. 
On  March  17,  2021,  a  defendant,  MSP  Recovery  Claims,  Series  LLC,  filed  its  notice  of  voluntary  dismissal.  On  March  30, 
2021, the remaining defendants, including Amgen, filed their motions to dismiss the second amended complaint.

On  April  27,  2021,  plaintiffs  filed  their  oppositions  to  defendants’  (including  Amgen’s)  motion  to  dismiss,  and 
defendants’ reply was filed on May 25, 2021. A hearing on defendants’ motion to dismiss was held in the Delaware District 
Court on July 13, 2021.

On March 11, 2022, the Delaware District Court granted defendants’ (including Amgen’s) motion to dismiss except as to 
the reverse payment claim and various state law claims from ten of the states in which plaintiffs reside. On May 11, 2022, the 
parties filed motions asking permission to seek interlocutory appeal. The plaintiffs did not oppose Amgen’s motion and instead 
argued all issues should be appealed at this time. Amgen filed its opposition to plaintiffs’ motion on June 10, 2022, and reply 
briefs were filed on June 24, 2022.

Regeneron Pharmaceuticals, Inc. Antitrust Action

On May 27, 2022, Regeneron Pharmaceuticals, Inc. (Regeneron) filed suit against Amgen in the Delaware District Court 
for  federal  and  state  antitrust  and  unfair  competition  violations  and  tortious  interference  with  prospective  business  relations. 
Regeneron  alleges  that  Amgen’s  sales  contracting  practices  for  Repatha,  ENBREL  and  Otezla  with  key  insurers,  third-party 
payers  and  PBMs  have  harmed  the  sales  of  its  product  PRALUENT  and  focuses  on  two  primary  arguments:  that  Amgen 
improperly  bundled  sales  of  Repatha  with  ENBREL,  Otezla  and  potentially  other  products  and  sought  exclusive  or  de  facto 
exclusive formulary positioning for Repatha. Amgen’s initial responsive pleading, a motion to dismiss, was filed on August 1, 
2022.

On August 11, 2022, Amgen moved to stay the case pending the ultimate decision on the merits of the ongoing patent 
litigation between Amgen and Regeneron in Amgen Inc., et al. v. Sanofi, et al. On January 6, 2023, the Delaware District Court 
heard oral argument on the motion to stay and the motion to dismiss.

ChemoCentryx, Inc. Securities Matters

On May 5 and June 8 of 2021, ChemoCentryx and its Chief Executive Officer were named as defendants in two putative 
shareholder  class  actions  filed  in  the  U.S.  District  Court  for  the  Northern  District  of  California  (Northern  District  Court  of 
California).  These  cases  were  consolidated  into  Homyk  v.  ChemoCentryx,  Inc.  in  which  the  plaintiffs  allege  violations  of 
Sections 10(b) and 20(a) of the Securities Exchange Act in connection with statements regarding the New Drug Application for 
TAVNEOS and the underlying Phase 3 clinical trial, seeking an award of damages, interest and attorneys’ fees. On March 28, 
2022, the plaintiffs filed their consolidated amended complaint, and on May 19, 2022, ChemoCentryx moved to dismiss these 
claims.

On  January  25,  2022,  the  Board  of  Directors  and  certain  of  ChemoCentryx’s  officers  were  named  as  defendants  in  a 
putative  shareholder  derivative  action  filed  in  the  Northern  District  Court  of  California,  Napoli  v.  Schall,  and  on  March  11, 
2022, the Northern District Court of California stayed the action until judgment is entered in the Homyk v. ChemoCentryx, Inc. 
action. On December 5, 2022 the plaintiffs in Napoli filed a Notice of Voluntary Dismissal, and on December 22, 2022, the 
Court ordered the dismissal of the case.
