Directors’ Report 

The  Directors  present  their  report  and  audited  Consolidated  and  Company  Financial  Statements  of  ICON  plc  (“the 
Company”, “ICON”, "we", "our" or "us"), a public limited company incorporated in the Republic of Ireland, and its subsidiary 
undertakings (“the Subsidiaries”), with the Company and the Subsidiaries being together (“the Group”) for the year ended 
31 December 2022.

The Company’s ordinary shares are traded on the NASDAQ market. The Company is considered a foreign private issuer in 
the U.S. and accordingly it is not subject to the same ongoing regulatory requirements as a U.S. registered company with a 
primary listing on the NASDAQ market.   

These  Consolidated  and  Company  Financial  Statements  (together  “the  financial  statements”)  for  the  year  ended 
31  December  2022  are  prepared  in  accordance  with  IFRS  as  adopted  by  the  EU  and  meet  the  reporting  requirements 
pursuant  to  Irish  Company  Law.  In  addition  to  the  Consolidated  Financial  Statements  contained  in  this  annual  report,  we 
also  prepare  separate  consolidated  financial  statements  on  Form  20-F  pursuant  to  the  rules  and  regulations  of  the  U.S. 
Securities  and  Exchange  Commission  ("SEC")  and  in  accordance  with  accounting  principles  generally  accepted  in  the 
United States (U.S. GAAP). The Form 20-F (under U.S. GAAP) is a separate document, a copy of which may be obtained 
from the Company’s website www.iconplc.com. IFRS differs in certain respects from U.S. GAAP, details of which are set out 
on pages 149 to 153 of this annual report. 

Principal activities, business review and future developments

ICON  is  a  clinical  research  organisation  (“CRO”),  founded  in  Dublin,  Ireland  in  1990.  Over  thirty  years  we  have  grown 
significantly to become a leading global provider of outsourced development and  services to pharmaceutical, biotechnology, 
medical  device  and  government  and  public  health  organisations.  Our  mission  is  to  improve  the  lives  of  patients  by 
accelerating the development of our customers’ drugs and devices through innovative solutions.

We  are  a  public  limited  company  in  Ireland  and  operate  under  the  Irish  Companies Acts.  Our  principal  executive  office  is 
located at: South County Business Park, Leopardstown, Dublin 18, Republic of Ireland. The contact telephone number of 
this office is +353 1 2912000. Our website is www.iconplc.com.

The Group specialises in the strategic development, management and analysis of programmes that support all stages of the 
clinical development process from compound selection to Phase I-IV clinical studies. Our service offering includes clinical 
development,  functional  outsourcing  and  laboratory  services.  Our  clinical  development  services  include  all  phases  of 
development  (Phases  I-IV),  peri  and  post  approval,  data  solutions  and  site  and  patient  access  services.  Our  laboratory 
services  include  a  range  of  high  value  testing  services,  including  bionanalytical,  biomarker,  vaccine,  good  manufacturing 
practice  ("GMP")  and  central  laboratory  services.  We  also  offer  full-service  and  functional  service  partnerships  to  our 
customers. 

Since  ICON  was  founded,  the  Company  has  expanded  through  organic  growth,  together  with  a  number  of  strategic 
acquisitions to enhance its expertise and capabilities in certain areas of the clinical development process and to broaden the 
service portfolio and add scale to existing services. On 1 July 2021, the Company completed the Acquisition of PRA Health 
Sciences, Inc. ("PRA") ("the Acquisition") by means of a merger whereby Indigo Merger Sub, Inc., a Delaware corporation 
and  subsidiary  of  ICON,  merged  with  and  into  PRA,  the  parent  of  the  PRA  Health  Sciences  Group  ("the  Merger").  Upon 
completion  of  the  Acquisition,  PRA  and  its  subsidiaries  became  wholly  owned  subsidiaries  within  the  ICON  Group.  The 
financial statements presented herein reflect the results of the combined Company since the Merger completion on 1 July 
2021. The results of PRA in the period prior to 1 July 2021 are not reflected other than clearly stated & required by GAAP in 
these financial statements. 

The acquisition of PRA has transformed the scale and capabilities of the Company. The combined Company leverages its 
enhanced  operations  to  transform  clinical  trials  and  accelerate  biopharma  customers’  commercial  success  through  the 
development  of  much  needed  medicines  and  medical  devices.  The  new  ICON  has  a  renewed  focus  on  leveraging  data, 
applying technology and accessing diverse patient populations to speed up drug development.

The Group believes that it is one of a select number of CROs with the expertise and capability to conduct clinical trials in 
most  major  therapeutic  areas  on  a  global  basis  and  has  the  operational  flexibility  to  provide  development  services  on  a 
stand-alone basis or as part of an integrated “full service” solution. 

At 31 December 2022, the Group had approximately 41,100 employees, in 111 locations in 53 countries, creating one of the 
world's  most  advanced  healthcare  intelligence  and  clinical  research  organisations.  During  the  year  ended  31  December 
2022,  the  Group  derived  approximately  46.1%,  46.6%  and  7.3%  of  its  revenue  in  the  United  States,  Europe  and  Rest  of 
World, respectively.

Directors’ Report (continued)

We  have  achieved  strong  growth  since  our  foundation  in  1990,  as  a  global  provider  of  outsourced  development  and 
commercialization  services  to  pharmaceutical,  biotechnology,  medical  device  and  government  and  public  health 
organisations.  We focus our innovation on those factors that are critical to our clients - reducing time to market, reducing 
cost  and  increasing  quality.  Our  global  team  has  extensive  experience  in  a  broad  range  of  therapeutic  areas.  ICON  has 
been  recognized  as  one  of  the  world's  leading  CROs  through  a  number  of  high-profile  industry  awards  (see 
www.iconplc.com/awards).  

As  our  market  has  evolved,  biopharmaceutical  companies  are  tackling  productivity  challenges,  increasing  budget 
constraints  and  greater  demands  to  demonstrate  product  value;  all  of  which  are  placing  increased  pressure  on  their 
revenues and levels of profitability. However, these trends have generally been positive for CROs, as continued outsourcing 
has been adopted by these companies as they seek to create greater efficiencies in their development processes, convert 
previously fixed costs to variable, and accelerate time to market for new treatments.

Regulatory  and  reimbursement  pressures  will  increase  the  emphasis  on  late  stage  (post  marketing)  research,  while 
increasing  requirements  to  demonstrate  the  economic  value  of  new  treatments.  As  a  result,  outcomes  and  comparative 
effectiveness  research  will  most  likely  be  required  in  order  to  secure  on-going  product  reimbursement.  Furthermore,  we 
believe  advances  in  molecular  biology  and  genetics  will  drive  further  growth  in  innovation  in  the  long  term  which  in  turn 
should create further growth opportunities for both biopharma companies and their outsource development partners.

We expect that continued outsourcing will be a core strategy of clients in the near term as they respond to the increased 
pressures on their revenues and profitability. Larger clients were the first to form strategic partnerships with global CROs in 
an  effort  to  reduce  the  number  of  outsource  partners  with  whom  they  engage  and  to  reduce  inefficiencies  in  their  current 
drug  development  models.  More  recently  we  have  seen  the  increasing  adoption  of  this  partner  model  with  mid-tier 
pharmaceutical  and  biotechnology  firms  as  they  also  seek  to  drive  development  efficiencies. As  outsourcing  penetration 
increases,  we  believe  clients  may  seek  a  greater  level  of  integration  of  service  offerings  from  CROs,  although  some  will 
continue  to  purchase  services  on  a  stand-alone  basis.  Creating  greater  connectivity  and  “seamlessness”  between  our 
services  and  the  sharing  of  “real-time”  clinical,  operational  and  “real  world”  data  with  clients  will  therefore  become 
increasingly important for CROs. ICON will seek to benefit from this continued outsourcing by clients to grow our business 
by  increasing  market  share  with  our  existing  client  base  and  adding  new  clients  within  the  Phase  I-IV  outsourced 
development services market; the aim being to ensure we will be considered for all major Phase I-IV projects.

Delivery  of  our  mission  and  strategy  is  focused  on  our  four  strategic  pillars,  being  (i)  Patient Access  &  Engagement  (ii) 
Career Development & Employer of choice (iii) Enduring Customer Partnerships and (iv) Healthcare Intelligence & Applied 
Innovation. 

Our strategy is focused on the following areas:

Directors’ Report (continued)

Patient Access & Engagement

ICON has a focused patient, site and data strategy, which is helping us to improve site identification, study placement and 
patient recruitment and retention. 

Accellacare  is  ICON's  global  clinical  research  network  offering  customers  a  wide  range  of  stand-alone  and  integrated 
solutions at the site or in patients' homes as part of decentralized trials. Our patient centric approach accelerates study start-
up and increases patient recruitment and retention for pharmaceutical, biotechnology and medical device industries. 

The Accellacare Site Network encompasses more than 76 sites across 6 countries covering the United States and Europe. 
Accellacare  offers  a  quality  focused  clinical  research  infrastructure  delivering  value  and  benefits  to  sponsors. Accellacare 
supports  customers  with  faster  start-up. The  time  from  site  selected  to  site  initiation  visit  is  on  average  30%  faster  when 
compared  to  other  sites. Also, Accellacare  achieves  an  average  of  40%  more  patients  per  site  when  compared  to  other 
sites.

Accellacare In-Home Services takes study visits directly to patients where they live, work, study or play in all phases and 
therapeutic areas of clinical trials. By bringing trial visits directly to patients, we ease the burden of participating in clinical 
research to increase patient recruitment, retention and diversity. Accellacare In-Home Services has experience in more than 
400  clinical  trials,  tailoring  our  services  to  fit  each  study's  specific  requirements  across  more  than  55  countries.  This 
cohesive  approach  is  leading  to  higher  patient  recruitment  and  retention  rates. Accellacare  is  also  achieving  faster  study 
start-up  for  its  customers  through  efficiencies  gained  in  central  process  management  including  budget  and  contracting, 
which  can  otherwise  be  a  source  of  delay.  This  combined  with  a  finely  tuned  feasibility  approach  allows  the  network  to 
identify and recruit more patients to studies, in a wide range of therapeutic areas, in a shorter time frame. Accellacare is an 
important  part  of  the  integrated  patient,  site  and  data  strategy,  helping  us  to  improve  patient  recruitment  and  retention. 
Through  Accellacare  we  are  committed  to  delivering  on  the  promise  of  patient  centricity  in  clinical  research.  It  is  also 
providing  investigators  with  innovative  treatments  for  their  patients  with  a  quality-focused  clinical  research  infrastructure 
supported by experienced professionals globally.  

In 2021, Accellacare entered new partnerships with six research sites across four countries, expanding its global footprint 
and capabilities. Agreements with Asclepes Research and Olympian Clinical Research in the U.S., Curiositas ad Sanum and 
Intermed in Germany, Quironsalud in Spain, and KO-MED in Poland. Through these new partnerships, Accellacare is also 
enhancing its capability in the central nervous system (CNS) and immune-inflammation therapeutic areas.

In 2022 the continued expansion of the Accellacare Site Network increases access and engagement with investigative sites 
and its patients, with the goal of faster recruitment and reducing the overall time and cost associated with drug development 
for customers. Accellacare now has access to more than 9 million patients.

Finding  and  engaging  suitable  patients  to  conduct  clinical  trials  is  one  of  the  biggest  issues  facing  the  drug  development 
industry today. Less than 1% of the U.S. population participates in clinical trials and the performance of investigative sites 
that do take part in research is uneven, hard to predict and many trials do not meet the initial recruitment goals. The current 
market  challenge  in  patient  enrollment  creates  an  opportunity  for  ICON  to  differentiate  its  service  offering  and  we  are 
working  to  reduce  patient  recruitment  times  through  enhanced  site  and  investigator  selection  based  on  key  performance 
metrics  and  through  use  of  our  proprietary  FIRECREST  technology  which  is  used  to  train  and  support  sites  during  the 
development process. Our Accellacare and Oncacare site network alliances enhances our ability to enroll patients onto the 
clinical studies we perform. We have also developed strategic alliances with investigator site groups and healthcare systems 
in all major global research markets. In partnership with others, we are pioneering patient recruitment solutions that leverage 
cognitive  computing  to  transform  clinical  trial  matching  and  allow  a  data-driven  approach  to  deliver  the  right  patients  for 
trials.  One  Search  is  our  intuitive,  integrated  workflow  and  interrogation  tool  that  enables  access  to  multiple  data  sources 
and  provides  the  visualization  and  tools  necessary  for  optimum  site  identification  based  on  ICON  and  industry  data  of 
capability, experience and performance. Scoring on enrollment performance, speed of start-up and quality supports better 
site selection.

Career Development & Employer of choice

People  have  long  been  central  to  our  mission  to  improve  the  lives  of  patients  by  accelerating  the  development  of  our 
customers’  drugs  and  devices  through  innovative  solutions.  We  encourage  our  people  to  bring  flexibility,  innovation,  and 
determination  to  every  situation.  By  doing  so,  our  people  can  build  exciting  and  rewarding  careers,  and  deliver  results  to 
bring life-changing medicines to market and to maintain our success as an industry leader. 

Our leadership and talent programs contribute to the enhanced retention of our employees, better project deliverables for 
our customers and the enhanced financial performance of the business.

We  aim  to  be  an  industry  leader:  a  Company  where  talented  people  come  to  do  important  work,  a  place  where  our 
employees can shape the future of healthcare, grow their careers, and reach their full potential. We have long held a deep 
commitment to cultivating strong people practices. This includes competitive total rewards packages along with a focus on 
continuous learning. We nurture a culture of development and aim to boost engagement by supporting our people’s growth, 
both personally and professionally. We are dedicated to finding opportunities for our employees to grow and develop.

Our success depends on the knowledge, capabilities, and quality of our people. To improve their skills, we are committed to 
providing continuous learning. This commitment is underpinned by clearly defined competencies, which offer employees a 
clear path along which to develop skills and advance their careers.

To support employees at every stage of their career journeys, training and development programs are aimed at advancing 
scientific,  technical,  and  business  knowledge.  Programs  include  tailored  CRA  academies  and  a  range  of  project 
management curricula, therapeutic-focused programs, and people leader development programs.

Enduring Customer Partnerships

We  continue  to  focus  on  expanding  and  deepening  our  partnerships  with  existing  customers,  while  also  developing  new 
customer relationships. 

Strategic client relationships will increasingly manifest themselves in many different forms. Many of these relationships will 
require innovative forms of collaboration across ICON service areas and departments and will therefore require increased 
flexibility to offer services on both a standalone functional basis and as part of a fully integrated service solution. To support 
this objective, we continue to evolve our collaboration and delivery models, invest in technology that will enable closer data 
integration across our service areas and enhance our project and program management capabilities.

To  meet  the  evolving  needs  of  both  our  existing  and  new  clients  we  continue  to  enhance  our  capabilities  through  both 
organic service development and targeted acquisitions.   

During the year, we continued to enhance our scientific and therapeutic expertise to support our customers in specific areas 
including oncology, orphan and rare diseases, CNS, dermatology, infectious disease and women's health. 

ICON  has  extensive  experience  in  vaccine  clinical  development  for  commercial  businesses,  governments  and  NGOs, 
having participated in over 160 vaccine studies in the past five years. This experience enabled us to play a significant role in 
the  search  for  vaccines  and  treatments  for  COVID-19.  ICON  is  currently  or  has  conducted  a  total  of  over  130  COVID-19 
related trials.

Of particular note was our work in partnering with Pfizer and BioNTech on their investigational COVID-19 vaccine program - 
the first to announce positive efficacy results from a Phase 3, late-stage study of a COVID-19 vaccine and to receive 
Emergency Use Authorization in individuals 16 years of age or older from the U.S. Food and Drug Administration.

ICON mobilized a large global team of therapeutic and operational specialists to partner on the implementation of Pfizer‘s 
and BioNTech’s strategic plan and framework for the  monitoring of the trial, which included a high level of remote clinical 
monitoring  and  source  data  verification  in  addition  to  on-site  monitoring,  safeguarding  data  quality  and  integrity  in  the 
evolving  pandemic  environment.  The  team  combined  the  benefits  of  full  service  and  functional  service  provider  clinical 
operating models to increase efficiency and ensure rapid study start-up.

ICON  worked  with  153  sites  in  the  US,  Europe,  South Africa  and  Latin America  to  ensure  the  recruitment  of  more  than 
44,000  trial  participants  over  a  four-month  period  in  late  2020.  ICON  provided  site  training,  document  management  and 
operational support for patient Informed Consent Form review, coordinated eConsent in most countries, and assisted with 
clinical  supply  management  services.  Achieving  the  unprecedented  trial  timelines,  while  maintaining  high  standards  of 
quality, undertaken in response to the pandemic required collaboration and strong communication between the ICON and 
companies’ project teams.

Directors’ Report (continued)

We continue to target growth in under-penetrated CRO market segments. Penetration within medical device companies has 
lagged  that  of  bio-pharma  firms  but  is  beginning  to  accelerate.  EU  regulatory  reform  enacted  in  2017  has  been  a  further 
catalyst  to  growth  in  this  segment  as  it  included  stricter  requirements  to  perform  clinical  evaluations  and  post-sale 
surveillance. In early 2020, ICON acquired MedPass which has further enhanced our value offering in this area.  

We also invested significantly in our site and patient network (Accellacare), and consider our expertise and offering in this 
area as one of our strategic pillars effective from 2021.  

Healthcare Intelligence & Applied Innovation

Innovation  at  ICON  is  focused  on  the  factors  that  are  critical  to  our  clients.  We  develop  integrated  technologies  to 
significantly  enhance  the  efficiency  and  productivity  of  clients’  drug  and  device  development  programs,  providing  true 
transparency across all areas of a study.

ICON is focused on applying innovation that can help our customers improve their development outcomes. We are focusing 
this  innovation  in  three  critical  areas:  improving  clinical  trial  design  and  execution;  faster  and  more  predictable  patient 
recruitment; and evolving clinical trials to be more patient centric which includes data collection and analysis directly from 
patient’s digital devices. Our approach to developing solutions to these challenges incorporates partnering with best-in-class 
technology providers but is also supported by a suite of differentiated ICON proprietary technologies.

We have continued to invest in building our capabilities in the gathering, analysis and application of real world patient data 
within  both  the  clinical  trial  and  post-trial  observational  study  environments. Alongside  expanding  internal  capabilities,  we 
continue to develop innovative partnerships with providers of real world data including TriNetX. During 2018, we signed an 
agreement with Intel to deploy the Intel® Pharma Analytics Platform for use in clinical trials. The Intel platform is an artificial 
intelligence  solution  that  enables  remote  monitoring  and  continuous  capture  of  clinical  data  from  study  subjects  using 
sensors and wearable devices and can apply machine learning techniques to objectively measure symptoms and quantify 
the impact of new therapies.

ICON’s proprietary One Search tool helps identify optimum trial sites the first time. It synthesizes multiple data sources, 
applying AI machine learning and rich data visualization for optimum site identification, resulting in improved study start-up 
and site cycle times, significant reductions in the percentage of low performing sites and increasing the percentage of 
studies meeting planned First Patient In (FPI).

FIRECREST is ICON’s proprietary comprehensive site performance management system. It is a web-based solution which 
enables accurate study information, including protocol information, training manuals and case report forms, to be rolled out 
quickly  and  simultaneously  to  investigative  sites.  It  allows  site  behavior  to  be  tracked  to  ensure  training  is  understood, 
procedures are being followed and that timelines and study parameters are met. It can significantly reduce the number of 
data queries originated from investigator sites. FIRECREST is now integrated into the ICON Safety Reporting Solution and 
provides a Site Question Management Tool. 

ICON has also developed a patient engagement platform to support improved patient experience and enrollment in clinical 
trials. The web-based patient engagement platform, provides patients with study specific information and connectivity with 
the  nearest  investigative  site.  The  solution  supplements  patient  recruitment  outreach  by  sites  and  increases  visibility  of 
potential study participants for sponsors and sites. An easy to navigate, user friendly interface guides the patient to new and 
ongoing studies in their particular indication and a pre-qualification questionnaire helps to determine if the study is a right fit 
for them. If the patient decides to register interest, they are given the option to select their nearest investigative site. This 
establishes  connection  with  the  site  and  the  patient  can  then  choose  to  contact  the  site  or  ask  to  be  contacted  for  pre-
screening.

We  positively  impact  patients’  lives  by  understanding  their  journeys  and  how  they  can  benefit  from  drugs  currently  in 
development and on the market. We do this by developing a holistic, global data environment across pharmaceutical and 
biotech companies (development to commercial) that gives insights into patients, and how best to serve them. Alongside the 
application of these technology solutions we are also focused on innovation through the redesign and where appropriate the 
automation of current clinical trial processes.

Operational Excellence, Quality and Delivery

Quality  is  the  foundation  of  our  success.  The  quality  of  our  work  is  vital  to  our  mission  of  bringing  better  medications  to 
patients  around  the  world.  We  are  committed  to  maintaining,  supporting,  checking  and  improving  our  quality  systems  to 
meet or exceed the quality standards demanded by our clients, patients and regulatory authorities. We focus our innovation 
on the factors that are critical to our clients – reducing time to market, reducing cost and increasing quality – and our global 
team of experts has extensive experience in a broad range of therapeutic areas.

7

Directors’ Report (continued)

Quality project execution underpins all that we do and we have an ongoing focus on developing our people and processes 
to continue to enhance our service delivery. We also deploy supporting technologies which we believe will enable faster and 
deeper insights into the quality of trial data.  

We  are  focused  on  operational  excellence  across  our  support  functions,  and  we  operate  a  global  business  support 
infrastructure across functions including finance, information technology, facilities, human resources and legal. This enables 
us to enhance the service levels across these support areas whilst driving down the costs of the service provision.

Principal activities of the Company and Group

The  principal  activity  of  the  Company  is  to  act  as  a  holding  Company. The  Company  also  operates  branch  offices:  ICON 
Italy in Milan, ICON Poland in Warsaw, ICON Latvia in Riga and ICON Lithuania in Vilnius. These branches provide contract 
research services to the pharmaceutical industry. 

Acquisition activity

On 1 July 2021, the Company completed the Acquisition of PRA by means of a merger whereby Indigo Merger Sub, Inc., a 
Delaware  corporation  and  subsidiary  of  ICON,  merged  with  and  into  PRA  Health  Sciences,  Inc.,  the  parent  of  the  PRA 
Health  Sciences  Group  ("the Acquisition"  and  "the  Merger").  Upon  completion  of  the Acquisition,    PRA  became  a  wholly 
owned  subsidiary  within  the  ICON  Group.  ICON’s  acquisition  of  PRA  has  brought  together  two  high-quality,  innovative, 
growing  organisations  with  similar  cultures  and  values  to  create  one  of  the  world’s  leading  healthcare  intelligence  and 
clinical contract research organisations. The total value of the Merger consideration is $12.1 billion and has resulted in the 
recognition of goodwill of $8.1 billion, intangible assets of $5.0 billion and an associated deferred tax liability of $1.1 billion.

With approximately 41,100 employees across the globe, the new ICON has established relationships with a majority of the 
world’s top pharmaceutical and biotech companies. We believe the Company now has the expertise, technology, and data 
assets  to  lead  the  industry  into  a  new  paradigm  for  bringing  clinical  research  to  more  patients  and  enabling  expanded 
capabilities for customers. We believe the Merger will deliver a transformational effect on ICON through:

Scale: With a deeper clinical, commercialization and consulting services portfolio, a broader geographic footprint, 
depth in therapeutic expertise, and data-driven healthcare technology, the Company can deliver enhanced globally 
scaled expertise & solutions for all customers and patients.

Focus: The Company has a singular focus on clinical research and commercialization, leveraging transformational 
technology and innovation to execute clinical trials from Phase 1 to post-approval studies with the highest quality, 
expertise and speed. 

Speed to market: Our extensive services portfolio, digital and data technology capabilities, and enhanced access 
to more diverse patient populations, have been combined with flexible delivery approaches and partnership models 
– all with the aim of reducing development time and costs.

Results and dividends

The results for the financial year and state of affairs of the Group are set out in the Consolidated Statement of Profit and 
Loss,  the  Consolidated  Statement  of  Comprehensive  Income,  the  Consolidated  Statement  of  Financial  Position,  the 
Consolidated  Statement  of  Changes  in  Equity  and  the  Consolidated  Statement  of  Cash  Flows  on  pages  36  to  41

The Group commenced a multi-year restructuring programme in 2021 as part of the integration of PRA into the Group. This 
programme is expected to last four years and deliver $150 million in synergies on completion. The programme focuses on 
alignment of people and processes and involves a review of the Group's global office footprint.

Revenue for the year ended 31 December 2022 increased by $2,260.6 million, or 41.3%, to $7,733.4 million from $5,472.8 
million  for  the  year  ended  31  December  2021.  For  the  year  ended  31  December  2022  we  derived  approximately  46.1%, 
46.6% and 7.3% of our revenue in the United States, Europe and Rest of World, respectively. The increase in revenues in 
the year ended 31 December 2022 is due to the Merger and the impact the continued recovery from the COVID-19 global 
pandemic has had on operations including: our ability to ensure laboratory samples are collected and analysed on time, our 
ability  to  perform  on-site  monitoring  of  clinical  trials,  the  ability  of  patients  or  service  providers  to  travel,  and  our  ability  to 
travel.  The  Company  has  earned  revenue  from  clinical  trials  associated  with  COVID-19,  most  notably  with  the  Pfizer 
BioNTech COVID-19 vaccine programme.                                                                                                                                                                              

Revenues  from  our  top  five  customers  amounted  to  $2,187.4  million  in  the  year  ended  31  December  2022  compared  to 
$1,730.6  million  in  the  year  ended  31  December  2021  or  28.3%  and  31.6%  respectively. The  largest  of  these  customers 
related to a strategic partnership with a large global pharmaceutical company.

Revenue  in  Ireland  increased  by  $618.7  million  in  the  year  ended  31  December  2022,  to  $1,984.6  million,  compared  to 
$1,365.9  million  for  the  year  ended  31  December  2021.  Revenue  in  Ireland  during  the  year  ended  31  December  2022 
increased by 45.3% compared to an overall increase in Group revenue of 41.3%. Revenue in Ireland is principally a function 
of our global contracting model (see note 2 - Segmental information). Entities acquired as part of the Merger are currently 
being integrated into the global contracting model and this process remains ongoing at 31 December 2022.

Revenue in the Rest of Europe increased by $442.8 million or 37.7%, to $1,618.4 million, compared to $1,175.5 million for 
the  year  ended  31  December  2021.  Revenue  in  the  U.S.  increased  by  $993.6  million  or  38.6%,  to  $3,566.6  million, 
compared  to  $2,573.0  million  for  the  year  ended  31  December  2021.  Revenue  in  our  Rest  of  World  (‘Other’)  region 
increased by $205.5 million or 57.3%, to $563.9 million compared to $358.4 million for the year ended 31 December 2021. 
Revenue  has  increased  across  all  regions  principally  reflecting  the  Merger  completion  and  continued  recovery  from  the 
COVID-19 global pandemic.

$3,970.0 million for the year ended 31 December 2021. Direct costs consist primarily of investigator and other reimbursable 
costs,  compensation,  associated  fringe  benefits  and  routine  share-based  compensation  expense  for  project-related 
employees and other direct project driven costs. The increase in direct costs during the year arose due to an increase in 
headcount  and  a  corresponding  increase  in  personnel  related  expenditure  of  $919.1  million,  as  a  result  of  the  Merger, 
combined  with an  increase  in  other  direct  project  related  costs  of $182.3  million,  an  increase  in  laboratory  costs  of $10.0 
million,  an  increase  in  third-party  investigator  and  other  reimbursable  costs  of  $434.5  million  and  an  increase  in  travel 
related costs of $5.6 million. As a percentage of gross revenue, direct costs have decreased to 71.4% compared to 72.5% 
for the year ended 31 December 2021.

primarily  comprised  of  compensation,  related  fringe  benefits  and  routine  share  compensation  expense  for  non  project 
related employees, recruitment expenditures, professional service costs, advertising costs and all costs related to facilities 
and information systems. As a percentage of revenue, other operating expenses increased to 17.3% of  revenue, compared 
to  16.5%  of  revenue  for  the  year  ended  31  December  2021  (excluding  exceptional  items).  During  the  year,  general 
overhead costs increased by $49.5 million, facilities related costs increased by $38.2 million, depreciation and amortisation 
increased by $252.4 million, personnel related costs increased by $103.5 million and there was an increase of $3.3 million in 
marketing fees. These increases were partly offset by a decrease of $11.8 million due to foreign exchange movements and 
other immaterial decreases.

During the year ended 31 December 2022, the Company incurred $70.8 million for restructuring, transaction and integration-
related  expenses  associated  with  the  Merger.  The  charge  includes  transaction  and  integration  costs  of  $39.7  million 
associated  with  advisory  costs,  retention  agreements  with  employees,  accelerated  share  compensation  charges  and 
ongoing integration activities. 

The  Company  has  also  undertaken  a  restructuring  programme  following  the  announcement  of  the  Merger  to  review  its 
global office footprint, optimise its locations to best fit the requirements of the Company and reorganise its workforce to drive 
future growth. This programme has resulted in a charge of $31.1 million in the year ended 31 December 2022. In the year 
ended  31  December  2021,  a  restructuring  charge  of  $31.1  million  was  recognised  under  a  restructuring  plan  adopted 
following  a  review  of  operations.  The  restructuring  plan  reflected  resource  rationalisation  across  the  business  to  improve 
resource utilisation.

We expect to incur additional expenses associated with the Merger; however, the timing and the amount of these expenses 
depends on various factors such as, but not limited to, the execution of integration activities and the aggregate amount of 
synergies we achieve from these activities.

Merger.

Risks and uncertainties

Under Irish Company Law (Section 327 the Companies Act), the Directors are required to give a description of the principal 
risks and uncertainties which it faced at 31 December 2022. Details of the principal risks and uncertainties facing the Group 
are set out in Appendix A of this annual report and form an integral part of the Directors’ Report.

Directors’ Report (continued)

Financial risk management

Group financial risk management is governed by policies and guidelines which are reviewed and approved annually by the 
Board of Directors. These policies and guidelines primarily cover foreign exchange risk, credit risk, liquidity risk and interest 
rate risk. The principal objective of these policies and guidelines is to ensure the minimisation of financial risk at reasonable 
cost. The Group’s financial instruments comprise cash and cash equivalents, current asset investments, lease obligations 
and negotiated debt facilities. The main purpose of these financial instruments is to fund the working capital requirements of 
the Group, the cost of new acquisitions and ensure continued growth. The Group also occasionally uses derivative financial 
instruments  to  reduce  exposure  to  fluctuations  in  foreign  exchange  rates.  The  principal  financial  risk  facing  the  Group  is 
foreign exchange risk and interest rate risk. Other financial risks include credit risk and liquidity risk. Further details are set 
out in note 26 to the Consolidated Financial Statements and note 11 to the Company Financial Statements. The Group does 
not undertake any trading activity in financial instruments nor does it enter into any leveraged derivative transactions. The 
Group treasury function centrally manages the Group’s funding and liquidity requirements.  

Financing

In  conjunction  with  the  completion  of  the  Merger,  on  1  July  2021,  ICON  entered  into  a  credit  agreement  providing  for  a 
senior  secured  term  loan  facility  of  $5,515.0  million  and  a  senior  secured  revolving  loan  facility  in  an  initial  aggregate 
principal  amount  of  $300.0  million  (the  "Senior  Secured  Credit  Facilities"). The  proceeds  of  the  senior  secured  term  loan 
facility  were  used  to  repay  the  outstanding  amount  of  (i)  PRA’s  existing  credit  facilities  and  (ii)  the  Company's  private 
placement notes outstanding and fund, in part, the Merger. The senior secured term loan facility will mature in July 2028 and 
the  revolving  loan  facility  will  mature  in  July  2026.  The  credit  agreement  governing  the  Senior  Secured  Credit  Facilities 
provides  that  borrowings  denominated  in  U.S.  Dollars  will  bear  interest  based  on  the  London  Interbank  Offered  Rate 
("LIBOR") or other base rate (as elected by the borrower), plus an applicable margin. On November 29, 2022, the Company 
agreed with its lenders to the adoption of the Secured Overnight Financing Rate ("SOFR") as the benchmark rate within the 
Senior Secured Credit Facilities, thus LIBOR is no longer the benchmark rate available to the Company under the terms of 
the Senior Secured Credit Facilities. 

The  Company  repaid  $800.0  million  and  $513.8  million  of  the  senior  secured  term  loan  facility  for  the  years  ended 
December  31,  2022  and  2021,  respectively.  At  December  31,  2022  and  2021,  no  amounts  were  outstanding  under  the 
senior secured revolving loan facility with the exception of $4.5 million letters of credit given to landlords to guarantee lease 
arrangements.

In addition to the Senior Secured Credit Facilities, on 1 July 2021, the Company, issued $500.0 million in aggregate principal 
amount of 2.875% senior secured notes in a private offering. The senior secured notes will mature on 15 July 2026.

The Company has contractual liabilities for lease arrangements of $189.7 million which will be predominantly settled over 
the next five year period through cash payments.

Directors’ power to purchase and allot company shares

Subject to the provisions of the Companies Act, the Company may purchase any of its own shares. Every contract for the 
purchase of shares, or under which the Company may become entitled or obliged to purchase shares in the Company shall 
be  authorised  by  a  special  resolution  of  the  Company.  The  Company  may  cancel  any  shares  so  purchased  or  may  hold 
them as treasury shares or re-issue them.

A  resolution  was  passed  at  the  Company’s  Annual  General  Meeting  (“AGM”)  on  22  July  2016,  which  authorised  the 
Directors to purchase (buyback) up to 10% of the outstanding shares in the Company. This authorisation was renewed at 
the Company's AGM on each of 25 July 2017, 24 July 2018, 23 July 2019, 21 July 2020, 20 July 2021 and 26 July 2022. On 
3  October  2016,  the  Company  commenced  a  share  buyback  programme  of  up  to  $400  million.  The  share  buyback 
programme was completed during the year ended 31 December 2018 with a total of 4,026,576 ordinary shares redeemed 
for  a  total  consideration  of  $372.1  million.  On  8  January  2019,  the  Company  commenced  a  further  share  buyback 
programme  of  up  to  1,000,000  ordinary  shares  which  was  completed  during  the  year  ended  31  December  2019.  These 
shares  were  redeemed  by  the  Company  for  a  total  consideration  of  $141.6  million.  On  22  October  2019,  the  Company 
commenced  a  further  share  buyback  programme. At  31  December  2019,  35,100  ordinary  shares  were  redeemed  by  the 
Company  under  this  programme  for  a  total  consideration  of  $5.3  million.  During  the  year  ended  31  December  2020, 
1,235,218  ordinary  shares  were  redeemed  by  the  Company  under  this  buyback  programme  for  a  total  consideration  of 
$175.0 million. On 18 February 2022, the Company commenced a share buyback programme which was fully complete at 
31  March  2022.    Under  the  buyback  programme,  420,530  ordinary  shares  were  redeemed  by  the  Company  for  total 
consideration of $100.0 million.

All ordinary shares that are redeemed under the buyback programme will be cancelled in accordance with the constitutional 
documents of the Company and the nominal value of these shares transferred to an undenominated capital fund as required 
under Irish Company law.

Directors’ Report (continued)

Rights and Obligations attaching to the Company’s shares

The  authorised  share  capital  of  the  Company  is  €6,000,000  divided  into  100,000,000  ordinary  shares  of  €0.06  at 
31 December 2022. Holders of ordinary shares will be entitled to receive such dividends as may be recommended by the 
Board  of  Directors  of  the  Company  and  approved  by  the  shareholders  and/or  such  interim  dividends  as  the  Board  of 
Directors of the Company may decide. On liquidation or a winding up of the Company, all assets available for distribution will 
be paid out to the holders of the Company's ordinary shares. Holders of ordinary shares have no conversion or redemption 
rights.  On  a  show  of  hands,  every  holder  of  an  ordinary  share  present  in  person  or  proxy  at  a  general  meeting  of 
shareholders shall have one vote with no individual having more than one vote.

Change of control 

A certain number of the Group’s customer contracts allow the customer to terminate the contract in the event of a change in 
control of the Company.

The  Senior  Secured  Credit  Facilities,  details  of  which  are  set  out  in  note  23  to  the  Consolidated  Financial  Statements, 
provides that, upon the occurrence of a change of control, the obligations thereunder may be accelerated.

Furthermore, certain Group companies have entered capital grant agreements with the Irish government agency, Enterprise 
Ireland,  whereby  the  Group  covenants  that  the  controlling  interest  in  the  Company  will  not  change  without  Enterprise 
Ireland’s prior written consent, which will not be unreasonably withheld.  

Additionally, the Company's share option and restricted share unit plans contain change in control provisions which provide 
for the acceleration of the vesting and exercisability of outstanding options and awards of restricted share units in the event 
that a change in control occurs with respect to the Company. 

Corporate Governance 

The Company is listed on the NASDAQ Global Select Market. The Company complies with the corporate governance listing 
requirements  under  the  NASDAQ  marketplace  rules.  NASDAQ  may  provide  exemptions  from  certain  NASDAQ  corporate 
governance standards to a foreign private issuer in certain circumstances provided that the foreign private issuer properly 
notifies NASDAQ and makes the required disclosure except to the extent that such exemptions would be contrary to United 
States federal securities laws. 

The exemptions that the Company relies on, and the practices the Company adheres to, are as follows:

•

•

•

The Company is exempt from provisions set forth in NASDAQ Rule 5620(c), which requires each issuer (other 
than  limited  partnerships)  to  provide  for  a  quorum  in  its  by-laws  for  any  meeting  of  the  holders  of  common 
stock,  which  shall  in  no  case  be  less  than  33.33%  of  the  outstanding  shares  of  the  issuer’s  common  voting 
stock.  The  Company’s  Constitution  requires  that  only  3  members  be  present,  in  person  or  by  proxy,  at  a 
shareholder  meeting  to  constitute  a  quorum.  This  quorum  requirement  is  in  accordance  with  Irish  law  and 
generally accepted business practices in Ireland.

The  Company  is  exempt  from  provisions  set  forth  in  NASDAQ  Rule  5635(c)  which  requires  (other  than  for 
certain specified exceptions) shareholder approval prior to the establishment or material amendment of a stock 
option or purchase plan or other equity compensation arrangement made or materially amended, pursuant to 
which  stock  may  be  acquired  by  officers,  Directors,  employees  or  consultants.  Irish  law  does  not  require 
shareholder  approval  with  respect  to  equity  compensation  arrangements. Accordingly,  the  2019  Consultants 
and  Directors  Restricted  Share  Unit  Plan,  the  2013  Employees  Restricted  Share  Unit  Plan  and  the 
amendments  to  the  Employee  Share  Option  Plan  2008  and  Consultants  Share  Option  Plan  2008  were 
adopted by the Board of Directors without shareholder approval. 

The  Company  is  exempt  from  provisions  set  forth  in  NASDAQ  Rule  5605(b)(2),  which  requires  independent 
Directors to hold regularly scheduled meetings at which only independent Directors are present. Irish law does 
not  require  independent  Directors  to  hold  regularly  scheduled  meetings  at  which  only  independent  Directors 
are present. The Company holds regularly scheduled meetings which all of the Directors may attend and the 
Lead Independent Director may call meetings of the independent Directors and non-employee Directors of the 
Board, as appropriate, in accordance with the Lead Independent Director Charter.  

The Company's practices with regard to these requirements are not prohibited by Irish law.

Audit Committee

The Audit Committee meets a minimum of four times a year. It reviews the quarterly and annual financial statements, the 
effectiveness  of  the  system  of  internal  control  and  recommends  the  appointment  and  removal  of  the  external  auditors.  It 
monitors the adequacy of internal accounting practices and addresses all issues raised and recommendations made by the 
external  auditors.    The  Audit  Committee  pre-approves  all  audit  and  non-audit  services  provided  to  the  Company  by  its 
external auditors on a quarterly basis. The Audit Committee, on a case by case basis, may approve additional services not 
covered by the quarterly pre-approval, as the need for such services arises. The Audit Committee reviews all services which 
are  provided  by  the  external  auditor  to  review  the  independence  and  objectivity  of  the  external  auditor,  taking  into 
consideration relevant professional and regulatory requirements. The Chief Financial Officer, the Head of Internal Audit, the 
Chief  Administrative  Officer  and  General  Counsel  and  the  external  auditors  normally  attend  all  meetings  of  the  Audit 
Committee and have direct access to the Committee Chairperson at all times. The Audit Committee is currently comprised 
of three independent Directors: Rónán Murphy (Chairperson), Eugene McCague and Julie O'Neill. On April 26, 2022, Hugh 
Brady stepped down as a member of the Committee and Julie O'Neill joined the Committee.

undertakings to the Consolidated Financial Statements.

Political donations

The Group made no disclosable political donations in the period.  

Going concern

The  time  period  that  the  Directors  have  considered  in  evaluating  the  appropriateness  of  the  going  concern  basis  in 
preparing  the  2022  Consolidated  Financial  Statements  is  a  period  of  at  least  twelve  months  from  the  date  of  approval  of 
these financial statements (the "period of assessment").

The  Group  has  considerable  financial  resources  and  a  large  number  of  customers  across  different  geographic  areas. 
Having assessed the relevant business risks (see Appendix A) the Directors believe that the Group is well placed to manage 
these risks successfully and they have a reasonable expectation that ICON plc, and the Group as a whole, has adequate 
financial  and  other  resources  to  continue  in  operational  existence  for  the  period  of  assessment  with  no  material 
uncertainties. For this reason, the Group continues to adopt the going concern basis in preparing the consolidated financial 
statements.

Directors’ Report (continued)

Accounting records

The  Directors  are  responsible  for  ensuring  that  adequate  accounting  records  as  outlined  in  Section  281-285  of  the 
Companies Act, are kept by the Company. The Directors are also responsible for the preparation of the Annual Report. The 
Directors  have  appointed  professionally  qualified  accounting  personnel  with  appropriate  expertise  and  have  provided 
adequate resources to the finance function in order to ensure that those requirements are met. The accounting records of 
the  Company  are  maintained  at  the  Group’s  principal  executive  offices  at  its  registered  office  at  South  County  Business 
Park, Leopardstown, Dublin 18.  

Statement of relevant audit information

The Directors believe that they have taken all steps necessary to make themselves aware of any relevant audit information 
and have established that the Company's statutory auditors are aware of that information. In so far as they are aware, there 
is no relevant audit information of which the Company's statutory auditors are unaware.

Disclosure of non-financial information 

The  European  Union  (Disclosure  of  Non-Financial  and  Diversity  Information  by  certain  large  undertakings  and  groups) 
Regulations 2017 require disclosure of certain non-financial information by certain large undertakings and groups.  

We have sought to address the requirements of the legislation in the sections following. 

Business Model

Our mission is to improve the lives of patients by accelerating the development of our customers’ drugs and devices through 
innovative solutions. We are passionate about providing innovative solutions for customers, we are better together working 
as one team, we value diversity and care about the success of our people, and we care about doing the right thing. We are 
advancing  clinical  research  while  offering  customers  broader  and  deeper  experience,  scale,  and  focus,  complemented  by 
continuity of delivery and speed to market. Our business model is described in the preceding sections. Consistent with our 
values, we seek to not only operate in compliance with applicable laws but also to positively influence our global workforce, 
the communities that we operate in, the environment and society as a whole. Doing so makes us a stronger, more resilient 
organisation by every measure.

Our  business  model  is  described  in  the  "Principal  activities,  business  review  and  future  developments"  section  of  the 
Directors’ Report.

Our core values underpin our mission and drive a culture and mind-set of ownership at ICON. "Own It at ICON", as set out 
below, is a statement of values that has remained at the very heart of ICON’s culture, encouraging our people to seize the 
opportunity  and  bring  flexibility,  innovation,  and  determination  to  every  situation.  We  believe  our  culture  of  ownership 
personifies who we are as a Company — it also helps us apply our expertise, collaborate to get things done, and succeed at 
our mission.  

17

Directors’ Report (continued)

Our  values  underpin  how  we  work  together  to  deliver  on  our  mission  to  improve  the  lives  of  patients  by  accelerating  the 
development  of  our  customers’  drugs  and  devices  through  innovative  solutions.  These  values  and  our  Code  of  Ethical 
Conduct,  which  underpins  these  values,  form  the  core  of  what  we  do,  and  how  we  do  it.  It  applies  to  all  of  our  officers, 
directors,  employees,  consultants  and  agents  globally. All  employees  and  temporary  workers  are  mandated  to  complete 
global ethics training.

At ICON, we care about conducting business sustainably. We care about our people, patients, and the communities in which 
we  live.  We  care  about  doing  the  right  thing  and  we  are  committed  to  working  to  the  highest  ethical  standards  and 
demonstrating our commitment to honesty, transparency, and quality. As a testament to our commitment, we launched our 
“ICON Cares” program at the start of 2023 which incorporates all our Environment, Social and Governance (ESG), Diversity, 
Inclusion  and  Belonging  (DIB),  and  CSR  initiatives  into  one  program.  ICON’s  Environment,  Social,  and  Governance 
Committee  ("ESG  Committee")  brings  together  all  these  initiatives  and  efforts  under  one  umbrella  to  ensure  consistency, 
enhance monitoring, reveal areas for development and facilitate reporting to the Board. The ESG Committee is chaired by 
the  Chief  Administrative  Officer  and  General  Counsel  (CAO),  who  is  responsible  for  reporting  to  the  ICON  executive 
leadership  team,  the  Nominating,  Sustainability  and  Governance  Committee  and  the  Board  on  ESG  matters.  In  February 
2022,  the  Board  delegated  oversight  responsibilities  of  the  Company's  strategies,  activities,  and  risks  in  respect  to  ESG 
matters  to  the  Nominating  and  Governance  Committee,  which  was  renamed  the  “Nominating,  Sustainability  and 
Governance Committee” in April 2022. Accordingly, the CAO reports on ESG matters to the Nominating, Sustainability and 
Governance  Committee  and  reports  to  the  Board  on  an  annual  basis  whilst  also  providing  periodic  ESG  updates  to  the 
executive leadership team.

The ESG Committee is focused on developing our strategy and initiatives relating to the environment, social matters, health 
and  safety,  community  engagement,  corporate  governance,  sustainability,  and  other  public  policy  matters  relevant  to  the 
Company. The ESG Committee is a cross-functional management committee of the Company including representation from 
facilities,  health  and  safety,  corporate  communications,  finance,  legal,  investor  relations,  procurement,  commercial, 
marketing,  and  human  resources  departments.  The  Committee  assists  and  supports  executive  management  and  the 
Nominating, Sustainability and Governance Committee of the Company in:

•
•
•

determining and setting the strategy relating to ESG matters;
developing, implementing and monitoring initiatives and policies based on that strategy; and
communicating these strategies, initiatives, and their results.

18

Directors’ Report (continued)

We are committed to building and developing our ESG strategies and reporting. In 2020 we launched our ESG page on the 
ICON website and have an internal ESG page on our MyICON intranet portal to engage with our employees and provide 
information  and  updates  relating  to  ESG  matters  and  our  commitment  to  sustainability.  In  2021,  as  a  testament  to  our 
commitment to managing ICON responsibly and sustainably, we became a participant in the United Nations Global Compact 
(UNGC),  a  set  of Ten  Principles  covering  the  areas  of  human  rights,  labor,  environment,  and  anti-corruption.  In  our  2021 
ESG report, released in 2022, we reported under the newest Global Reporting Initiative (GRI) standards and the Task Force 
on Climate-Related Financial Disclosures (TCFD). Our report summarises our current policies, priorities, and commitments 
in  respect  to  ESG  matters.  During  2022,  ICON  received  a  silver  medal  from  EcoVadis  in  recognition  of  our  environment, 
social  and  governance  efforts  throughout  ICON.  The  ESG  page  on  our  website  is  available  at  https://www.iconplc.com/
about/esg/.

The  global  landscape  in  respect  to  regulatory  and  legislative  requirements  relating  to  ESG  reporting  and  disclosure 
requirements is rapidly evolving, and we are monitoring potential requirements so that we are positioned to adhere to any 
additional  requirements  in  due  course,  particularly  with  respect  to  the  requirements  of  the  draft  European  Sustainability 
Reporting Standards (ESRSs) which are expected to be effective from 1 January 2024.

Building a sustainable future – our commitment to the United Nations Sustainable Development Goals

As  a  global  Company,  we  maintain  an  ethical  and  sustainable  presence  in  hundreds  of  locations  worldwide. At  its  core, 
ICON’s  mission  is  to  improve  health  and  lives.  We  are  also  committed  to  contributing  to  the  2030  United  Nations 
Sustainable Development Goals (SDGs) and are proud that our work contributes to their advancement.

Our  research,  our  work  with  customers  and  patients  and  our  on-the-ground  efforts  to  meet  the  diverse  needs  across  our 
communities  align  with  the  SDGs.  These  efforts,  however,  focus  on  a  subset  of  themes  where  we  have  the  greatest 
opportunity to effect change and further details are set out in our ESG Report.

Environmental matters 

ICON  is  committed  to  delivering  excellence  in  care  to  our  communities.  To  improve  our  overall  sustainability,  this 
commitment means tracking and improving our environmental performance across all business activities. We achieve this 
by pursuing sustainability strategies that recognize the impact of our operations as a CRO on the environment, addressing 
greenhouse  gas  (GHG)  emissions,  energy  use,  waste  generation  and  procurement-related  activities.  Our  employees, 
directors, officers, contractors, and temporary workers are expected to support our sustainability objectives. 

Our  Global  Environmental  Management  Policy  and  Environmental  Management  Plan  is  our  program  for  managing 
environmental sustainability initiatives. The implementation of the program is led by our facilities team, reporting to our Chief 
Administrative  Officer  and  General  Counsel  (CAO).  The  CAO  is  responsible  for  reporting  on  the  program  to  the  ICON 
executive leadership team and Nominating, Sustainability and Governance Committee and the Board.

ICON  set  environmental  goals  around  the  use  of  renewable  energy  and  carbon  emissions  in  2019  and  we  are  working 
towards achieving these goals which are as follows: 

•
•
•

100% renewable electricity by 2025
20% reduction in kilowatt hours (kWh) of electricity by 2030
Net zero carbon emissions on Scope 1 & 2 by 2030

We  have  programs  in  place  to  manage  and  minimize  climate  impacts  of  business  activities.  To  continue  to  improve 
processes  and  reduce  our  environmental  impact,  we  track,  calculate,  and  report  our  GHG  footprint.  We  apply  the  GHG 
Protocol  Corporate  Standard,  which  is  the  global  corporate  accounting  and  reporting  standard  for  calculating  carbon 
emissions. Carbon Trust provides annual verification of our emissions data. 

In line with carbon reduction targets, ICON’s combined Scope 1 and 2 GHG emissions, relative to revenue and the number 
of employees, have fallen year on year since 2018. Since 2018, following our reduction efforts, the pandemic-related closure 
of  many  of  our  facilities  and  a  reduction  in  business  travel,  GHG  emissions  across  our  operations  declined  significantly. 
Since 2021, as more normal operations resumed, we have seen a decrease in combined Scope 1 and 2 emissions with an 
overall  increase  in  our  total  GHG  emissions  due  to  an  increase  in  business  travel  (Scope  3).   As  the  pandemic  recovery 
continues, and we have resumed more normal operations, we are evaluating additional opportunities to continue to reduce 
our carbon emissions across our organisation to develop and improve our environment program.

CDP (formerly the Carbon Disclosure Project) provides a globally recognized system that enables companies to measure 
and manage their environmental impacts. ICON continues to be committed to improving its current scoring of a C.

Directors’ Report (continued)

We  are  focused  on  reducing  energy  use  across  our  global  operations.  For  example,  reducing  energy  use  and  shifting  to 
renewable energy are components of our specific environment goals. Waste reduction is embedded into our environment 
policies  and  practices  and  is  one  of  the  objectives  of  ICON’s  Environmental  Management  Policy.  We  will  seek  new 
opportunities to reduce waste by increasing recycling volumes, reducing consumption of primary materials, and decreasing 
use of disposable products in our offices and facilities. 

The majority of our sites are leased, and we work closely with our landlords and leasing agents to implement measures to 
ensure  we  operate  in  an  environmentally  sustainable  manner.  The  Acquisition  of  PRA  expanded  our  global  real  estate 
footprint  and  our  real  estate  group  worked  with  other  business  leaders  to  understand  the  sustainability  implications  and 
opportunities of this new footprint and find ways to continue to advance our collective sustainability goals. During 2022, we 
continued to integrate offices and reduce our footprint which resulted in downsizing or closing 31 locations to align with new 
working styles and business needs. When selecting new locations for offices and planning building modifications, experts 
from our real estate team factor in environmental considerations. In addition, we have implemented a series of measures 
globally to reduce the local footprint of our offices, such as installing energy-efficient LED lighting, using motion detectors to 
reduce  energy  use,  purchasing  recycled  office  supplies,  and  reducing  paper  consumption  by  promoting  paperless  office 
processes, or where printing is necessary, enabling double-sided output. 

Our office design has efficiency in mind, utilizing space to provide the maximum number of desks and functional provisions 
while still providing comfortable, safe spaces for our employees. Our strategies include:

•
•
•
•

Perimeter glazing of meeting rooms, offices, and other spaces which allow in natural light.
Recycling areas built into business centers and kitchen/ canteens which reduce waste sent to landfills.
Planted green spaces which contribute to internal air quality, temperature, and humidity.
Building materials and vendors which we select for low environmental impact.

We also require our suppliers to abide by our Global Supplier Code of Conduct which includes a commitment to comply with 
applicable  environment  laws  and  regulations,  our  expectations  around  waste  management  and  sustainable  use  of 
resources.  

Social and Employee matters

Community Engagement

We  are  committed  to  making  a  positive  impact  on  the  communities  in  which  we  work  and  live  and  we  have  aligned  our 
community  efforts  to  a  broader  vision  for  social  impact,  including  by  aligning  priorities  with  our  organisational  goals  of 
diversity, inclusion, and belonging.

Our community engagement activities are focused on two core areas:

•
•

Supporting education and building closer ties between industry and academia.
Improving the welfare of people in the communities in which we live.

Supporting education and building closer ties between industry and academia 

A core area of community support includes building ties between industry and academia to inspire the next generation of 
leaders in business and science. Our existing partnerships continue with the following organisations:

▪

▪

•

The  ICON-McKeon  Research  Fellowship  in  Motor  Neuron  Disease  ('MND')  in  honor  of  Mr.  Declan  McKeon, 
former Board member, acting Chairman, Lead Independent Director and Chair of the ICON Audit committee. The 
ICON-McKeon  Research  Fellow  in  MND  carries  out  research  in  the  areas  of  machine-learning  and  artificial 
intelligence  to  derive  insights  from  multimodal  clinical,  imaging  neuro-electric  signaling,  in  the  context  of  the 
neurodegenerative disease of ALS. 

Partnership with Trinity Centre for People with Intellectual Disabilities ('TCPID') - TCPID situated within the 
School of Education, Trinity College Dublin, aims to promote the inclusion of people with intellectual disabilities in 
education  and  society.  The  Centre  provides  people  who  have  intellectual  disabilities  with  the  opportunity  to 
participate  in  a  higher  education  program  designed  to  enhance  their  capacity  to  fully  participate  in  society  as 
independent adults. The 2-year education program includes work placements and internships to enable students to 
experience  and  participate  in  the  work  environment.  In  2022,  ICON  facilitated  a  12-month  internship  in  our 
Laboratory  and  Facilities  departments  for  one  of  the  TCPID  graduates  and  our  aim  is  to  continue  to  offer  work 
placements and internships as part of this partnership in 2023.

Partnership with Junior Achievement to inspire schoolchildren. Junior Achievement encourages young people 
to  remain  in  education  and  teaches  them  the  skills  they  need  to  succeed  in  a  changing  world.  ICON  volunteers 
take time out of their working day to deliver Junior Achievement programs, teaching primary and secondary-level 

20

Directors’ Report (continued)

students  valuable  business,  STEM  and  entrepreneurship  skills  that  will  serve  them  throughout  their  professional 
lives. ICON expanded its partnership with Junior Achievement to include an additional three locations in the United 
States and the United Kingdom in 2022.

In 2022, we further expanded our industry-academia partnerships through the creation of a new ICON scholarship program 
to  provide  increased  opportunities  for  underrepresented  groups  to  study  STEM  (Science,  Technology,  Engineering  & 
Mathematics)  courses  and  to  build  a  more  diverse  graduate  pool  of  talented  and  ambitious  STEM  professionals  who  can 
help  to  ensure  the  future  success  of  the  life  sciences  industry.  Through  the  program,  ICON  is  partnering  with  three 
universities in Ireland – Dublin City University (DCU), Trinity College Dublin (TCD) and the University of Limerick (UL) – as 
well as with the Thurgood Marshall College Fund (TMCF) in the US, to fund 33 scholarships for students of STEM courses. 
TMCF  is  a  not-for-profit  organisation  that  supports  nearly  300,000  students  attending  its  47  member-schools  that  include 
publicly-supported Historically Black Colleges and Universities (HBCUs).

Improving the welfare of people in the communities in which we live

Through  volunteering,  donations  and  other  charitable  initiatives,  our  employees  across  the  world  are  making  a  positive 
difference  to  their  communities.  We  support  causes  that  are  important  to  our  employees  and  have  several  programs  that 
support the welfare of people in our local communities. In 2022, 540 employees across the world participated in Run in the 
Dark, an annual event organized by the Mark Pollock Foundation to bring people together and fundraise to help find a cure 
for  paralysis.  ICON  was  the  largest  global  corporate  team  to  participate  in  the  event  and  helped  to  raise  $10,000  for  the 
cause. A  team  of  90  ICON  cyclists  from  19  countries  also  participated  in  our  annual  ICON  cycle  challenge,  which  raised 
funds for the International Committee for the Red Cross.

Since  2012,  ICON’s  annual  employee-nominated  charity  donation  program  has  supported  over  90  charities,  donating 
$10,000  to  each  organisation.  The  selected  organisations  focus  on  a  range  of  critical  issues,  from  relieving  poverty  and 
homelessness  to  improving  child  welfare  through  education  and  enhancing  the  lives  of  people  living  with  a  variety  of 
diseases. The organisations were chosen to align with our ESG goals. In addition, to support ongoing humanitarian efforts in 
Ukraine,  we  also  made  a  donation  to  the  Children  of  Heroes  charity  fund  in  Ukraine  to  support  children  who  have  been 
severely impacted by the war in that region.

Talent and People 

Our people are core to our ability to deliver our services and drive better patient outcomes. Through diversity, inclusion and 
belonging, industry-leading talent management practices, a sincere attention to our employees’ needs, well-being and health 
and safety, we continue to power the potential of together. 

At the core of our strategy is our people 

People  have  long  been  central  to  our  mission  to  improve  the  lives  of  patients  by  accelerating  the  development  of  our 
customers’  drugs  and  devices  through  innovative  solutions.  We  encourage  our  people  to  bring  flexibility,  innovation,  and 
determination  to  every  situation.  By  doing  so,  our  people  can  build  exciting  and  rewarding  careers,  and  deliver  results  to 
bring life-changing medicines to market and to maintain our success as an industry leader.

Learning and development of our staff is a key focus for us

Our leadership and talent programs contribute to the enhanced retention of our employees, better project deliverables for 
our customers and the enhanced financial performance of the business.

We aim to be an industry leader where talented people come to do important work and where our employees can shape the 
future of healthcare, grow their careers, and reach their full potential. We have long held a deep commitment to cultivating 
strong  people  practices. This  includes  competitive  total  rewards  packages  along  with  a  focus  on  continuous  learning.  We 
nurture  a  culture  of  development  and  aim  to  boost  engagement  by  supporting  our  people’s  growth,  both  personally  and 
professionally. We are dedicated to finding opportunities for our employees to grow and develop.

Our success depends on the knowledge, capabilities, and quality of our people. To improve their skills, we are committed to 
providing continuous learning. This commitment is underpinned by clearly defined competencies, which offer employees a 
clear path along which to develop skills and advance their careers. 

To support employees at every stage of their career journeys, training and development programs are aimed at advancing 
scientific,  technical,  and  business  knowledge.  Programs  include  tailored  CRA  academies  and  a  range  of  project 
management  curricula,  therapeutic-focused  programs,  and  people  leader  development  programs.  During  2022,  this  also 
included  diversity,  inclusion  and  belonging  training  for  everyone  on  our  talent  acquisition  team  and  many  of  our  People 
Leaders.

21

Directors’ Report (continued)

Our  People  Leader  development  program  focuses  on  providing  our  People  Leaders  with  the  relevant  skills  to  effectively 
manage  themselves,  their  team  and  their  business,  including  psychometrics  to  raise  their  awareness  of  their  behavioral 
preferences  and  the  preference  of  others.    ICON  also  invested  in  Harvard  Manage  Mentor,  an  online  learning  platform 
providing  People  Leaders  with  access  to  learning  available  at  any  time  with  topics  ranging  from  change  management, 
diversity & inclusion, retaining employees and developing employees.

We provide our people with a personalized and flexible learning experience, delivered through a combination of in-person 
and  technology-driven  programs  that  suit  their  learning  styles  and  can  flex  to  suit  their  schedules.  Through  our  industry 
leading  CareerHub,  ICON  employees  are  encouraged  to  broaden  their  scientific,  technical,  leadership,  and  business 
knowledge. By tapping into development programs and partnerships with leading academic institutions, team members can 
use the hub to develop competencies that advance their careers. We also collaborate with UCD Smurfit School Executive 
Development to deliver customized leadership development programs for global employees.

As an organisation we are keen to hear directly from our employees

To attract and retain the best talent, we must listen and respond to employees’ needs. This begins with a focus on diversity, 
inclusion  and  belonging,  and  extends  to  every  aspect  of  our  work,  from  recruitment  and  onboarding,  to  training, 
engagement, enablement, and reward. We pursue  best-in-class approaches to building employee engagement and  these 
include, among others:

•

•

•
•

•

Comprehensive global employee surveys, which measure how people feel about their work and whether they feel 

they have the tools to do their jobs well. Feedback from these studies informs detailed action plans at the group, 

function, and team level.

Pulse check surveys, which are smaller-scale studies designed to measure employee sentiment on specific topics 

and initiatives.

Fostering an environment of diversity, inclusion and belonging where everyone is valued.

Stay  interviews  to  help  managers  understand  why  staff  stay  and  to  uncover  what  might  put  them  at  risk  of 

departing.

Skip-level meetings to develop trust and rapport between senior leaders and employees.

Our  listening  strategy  supports  our  efforts  to  reduce  employee  turnover,  which  we  monitor  closely  through  analytics. 
Qualitative  information  is  collected  through  formal  exit  interviews  and,  where  we  believe  they’ll  make  an  impact,  we 
intervene via retention plans and related efforts.

Employee well-being 

ICON’s commitment to improving health and enriching lives extends beyond the work we do with our customers. Employees 
across the globe have direct access to locally relevant information and resources to support every facet of their well-being, 
including physical, social, psychological, and environmental.

Our global Employee Assistance Program (EAP) ensures that all employees, and their families, have access to a range of 
different, confidential resources and experts to help them better manage their working life and personal life. The EAP also 
delivers a web-based and mobile app platform with access to toolkits providing advice and resources in local languages.

Health and safety

At ICON, the health and safety of our employees, customers and clinical trial patients are our most important priorities. We 
take guidance from global and regional health authorities and governments to protect the safety and welfare of employees, 
as well as abide by government directives. Our global health and safety management system ensures we deliver on all local 
and  national  requirements.  Our  priority  objectives  are  the  safety  of  our  staff,  clinical  trial  patients,  protecting  the 
environment, maintaining business continuity, and ensuring all sensitive health and safety data is protected.

We  are  committed  to  providing  a  safe  working  environment  for  our  people.  We  achieve  this  goal  by  working  in  ways  that 
protect the safety, health, and welfare of all our employees, clinical trial patients, and visitors. Risk assessment is the basis 
of  the  safety  management  system,  and  we  work  to  identify,  mitigate,  and  monitor  existing  and  emerging  health  or 
environment risks that may be associated with our business activities. We work to identify, mitigate, and monitor existing and 
emerging health or environment risks that may be associated with our business activities.

Fostering diversity, inclusion and belonging

We believe in a workplace culture that embraces diverse perspectives and empowers our team members to grow, whether 
at  work,  at  home  or  in  their  communities. The  diversity  of  our  teams  is  critical  to  our  success. As  a  global  operation,  we 
deliberately  structure teams to be diverse to support  the delivery of our customers’ clinical development programs across 
multiple geographies and communities.

Diversity, inclusion, and belonging (DIB) are fundamental to our culture and values. Diversity makes us more innovative and 
more  creative,  which  helps  us  better  serve  our  patients,  our  customers,  and  our  communities.  We  recognize  the  critical 
importance of diversity in clinical trials ensuring all types of patients who will eventually receive therapies are represented on 
clinical  trials,  as  well  as  offering  clinical  trials  as  a  care  option  for  those  who  may  not  otherwise  have  access  to  medical 
treatment.

We are committed to being a workplace where all employees are included and feel a sense of belonging. To achieve this, 
we  acknowledge  and  celebrate  our  differences  in  gender,  ethnicity,  culture,  and  abilities. As  a  values-driven  organisation, 
respect  for  diverse  points  is  foundational  to  how  we  interact  with  each  other,  as  well  as  with  customers,  patients,  and 
suppliers.

ICON’s approach to DIB is a key focus area. To reflect this, inclusion is one of our core values and our DIB strategy is now 
organized into four key ambitions:

ICON’s  DIB  practices  and  programs  are  viewed  through  the  lens  of  our  four  DIB  ambitions.  Each  ambition  has  sponsors 
from our executive leadership team to support and drive the agenda and provide leadership. 

We  believe  in  a  workplace  culture  that  embraces  diverse  perspectives  and  empowers  our  team  members  to  grow  —  at 
work, at home and in their communities. The key areas of focus for our diversity, inclusion, and belonging agenda include 
talent management, country-level inclusion policies, rewards, training, and communications.

We established a Diversity, Inclusion & Belonging Steering Committee in 2019 which brings together individuals from across 
ICON  to  develop  and  execute  work  streams  under  each  of  the  four  ambitions,  with  a  central  team  overseeing  the 
overarching  efforts.  ICON  has  Diversity,  Inclusion  &  Belonging  advocates  from  across  our  global  employee  population  to 
better  understand  local  needs,  build  local  presence  and  awareness,  and  to  give  a  voice  to  every  corner  of  the  company 
across the world. These individuals play a key role in supporting the Diversity, Inclusion & Belonging Steering Committee 
and in aligning activities across the organisation.

Directors’ Report (continued)

The DIB community groups we have at ICON are:

DAWN: The Disability Awareness Network is a community group striving to develop and foster a 
mindset  towards  creating  an  inclusive  workplace  and  working  environment  where 
everyone is treated equally with respect and dignity, irrespective of any visible or hidden 
disabilities.

EmbRACE: Supporting all race and ethnic backgrounds in creating an inclusive workplace culture.

NOW@ICON: Networking  organisation  for  Women  at  ICON  is  committed  to  inspiring  and  connecting 
current and potential leaders through an inclusive environment of targeted initiatives and 
supportive mentorship.

Pride@ICON: Supporting  LGBTQ+  colleagues  and  allies,  ensuring  that  no  matter  where  employees 
are in the world, our offices are a safe space where they are welcomed, respected, and 
valued.

SPACE: Supporting Parents and Carers Everywhere to create a workplace where stepping out of 
careers  due  to  personal  commitments  for  a  period  is  wholly  accepted  and  not  career 
limiting, and where stepping back into their career is an organic and positive process.

As a testament to our commitment to diversity, ICON are aiming for gender parity at the VP level and above by 2025. As at 
31 December 2022, women represent 42% of the positions at the VP level and above.

ICON is focused on building an inclusive culture where employees feel supported by a fair system supporting pay equity.  
We have a long track record of developing talent and filling vacancies through internal hires. Using best-in-class analysis, 
we conduct regular reviews of salary ranges to ensure fair pay, irrespective of gender, race, or ethnicity whilst considering 
legitimate business factors that explain differences such as performance, tenure, and experience.

We continuously monitor and seek to maintain pay equity for our employees. We have structured our pay principles so that 
individual differences not related to tenure, experience or performance criteria are not a factor in how we deliver rewards. 
ICON has made significant investments in organisational design structures, tools and education that uphold and support our 
pay principles.

We are committed to ensuring fair employment practices. For every jurisdiction in which we operate, we act in compliance 
with relevant laws relating to labour rights and labour relations as well as market competitive benefits. We believe in fair and 
equal  treatment  for  all  our  people,  without  regard  to  gender,  race,  ethnicity,  sexual  orientation,  marital  status,  physical  or 
mental  disability,  age,  pregnancy,  veteran  status,  nationality,  religion,  or  any  other  legally  protected  status.  We  do  not 
tolerate our employees being subjected to physical, sexual, racial, psychological, verbal, or any other form of harassment. 
We  encourage  our  employees  to  report  any  issues  of  harassment  or  discrimination.  We  prohibit  retaliation  against  any 
employee who rejects, protests, or complains about unlawful discrimination or harassment.

For further details on risks relating to employee matters refer to Appendix A: Risk Factors.

Directors’ Report (continued)

Human rights

ICON is committed to human rights and in 2021, ICON became a participant in the UN Global Compact (UNGC), signalling 
our commitment to uphold the UNGC’s 10 Principles, including those related to human rights across our global operations. 
Our business model and our policies, including our Global Code of Ethical Conduct and Global Supplier Code of Conduct, 
are intended to fully comply with applicable human rights legislation in the countries where we operate. Our zero-tolerance 
policy on forced labour, slavery, and human trafficking is defined clearly in these policies, which are available to employees, 
suppliers, customers, and the public.

We are opposed to forced labour, slavery, and human trafficking. We will not knowingly support or conduct business with 
any  organisation  involved  in  such  activities.  We  do  not  employ  anyone  below  the  minimum  employment  age  in  the 
jurisdictions in which we operate.

Our  Global  Supplier  Code  of  Conduct  incorporates  the  Pharmaceutical  Supply  Chain  Initiative  (PSCI)  principles  for 
responsible  supply  chain  management,  including  for  labour.  Before  doing  business  with  ICON,  suppliers  must  certify  that 
they  will  comply  with  the  ICON  Global  Supplier  Code  of  Conduct  or  their  own  materially  equivalent  internal  code,  which 
includes  human  rights  protections.  We  perform  pre-engagement  due  diligence  on  our  suppliers,  including  in  relation  to 
labour  issues,  which  we  support  through  periodic  re-screening.  We  hold  our  suppliers  accountable  for  meeting  their 
contractual obligations. Contract non-compliance can result in termination of the business relationship with the supplier and 
exclusion from future business.

Ethics and Compliance

ICON’s commitment to ethics and integrity is embedded in our company values. We act with integrity and integrate ethical 
principles into our business practices and culture. ICON’s Global Code of Ethical Conduct (the Code) establishes our core 
principles  and  standards  for  honest,  fair,  and  ethical  behaviour.  This  Code  addresses  the  core  values  expected  of  our 
people  in  our  internal  interactions  with  each  other  as  well  as  in  external  dealings  with  patients,  customers,  healthcare 
professionals, regulators, investors, vendors and other third parties.

Our Ethics and Compliance program builds on the principles established in the Code to define and drive business conduct 
consistent with company values and the laws, rules and regulations that apply to our business. The Ethics & Compliance 
Team  (E&C)  provides  day-to-day  independent  oversight  for  the  program.  The  team  is  independent  of  the  business  and 
reports  to  the  Chief  Administrative  Officer  and  General  Counsel  (CAO).  The  CAO  reports  on  the  program  to  ICON’s 
executive  leadership  team,  the  Nominating,  Sustainability  and  Governance  Committee  and  the  Board.  The  program 
supports  all  functional  areas  globally  and  is  dedicated  to  the  implementation  of  standardized  global  policies,  procedures, 
training, guidance, communications, monitoring, investigations, issue management, assessing compliance-related risk and 
mitigations, and reporting to ensure the overall compliance program is effectively functioning. 

ICON has incorporated a third-party system, Ethics Line, for employees and third parties to confidentially report ethics and 
compliance questions, as well as concerns, and to track reports through follow-up and resolution. These tools also provide 
visibility into our risks while highlighting opportunities to address them. ICON’s compliance and ethics program will continue 
to grow and evolve in response to changes in our business and in the global business climate.

All employees are required to complete mandatory training in key areas which support our values and our ways of working. 
The training incorporates the key principles of our policies and codes and includes interactive scenarios where applicable.

At ICON, we promote a Speak Up culture that encourages compliance, openness, and accountability without retaliation. The 
Speak  Up  Policy  aims  to  support  our  culture  and  values  and  seeks  to  encourage  the  prompt  reporting  or  surfacing  of 
concerns or violations. Reported ethics concerns and other ethics and compliance-related data are reported via the CAO to 
the Board as appropriate.

For further details on risks relating to ethics and compliance refer to Appendix A: Risk Factors.

Directors’ Report (continued)

Anti-bribery and Corruption 

ICON is guided by the foundational principle that we do not tolerate bribery or any other form of corruption or fraud. Our anti-
bribery and anti-corruption (ABAC) program is a key element of our Ethics and Compliance Program. ICON and all ICON 
directors,  employees,  consultants,  agents  and  all  third  parties  acting  on  ICON's  behalf  must  act  in  compliance  with 
international  laws  and  regulations  relating  to  bribery,  corruption,  and  illicit  payments,  including  the  US  Foreign  Corrupt 
Practices Act and the UK Bribery Act 2010.

ICON  maintains  the  ISO  37001:2016  certification  for  our  Anti-Bribery  Management  System,  which  establishes  the 
framework  for  the  controls  that  prevent,  detect  and  mitigate  the  risk  of  bribery.  Our  program  is  designed  to  ensure  our 
compliance with anti-corruption laws, including due diligence, training, policies, procedures, and internal controls.

Bribery  and  corruption  remain  a  business  risk  as  we  conduct  our  business  across  the  globe  and  enter  partnerships  and 
collaborations. There is no certainty that all employees and third-party business partners (including our vendors, suppliers, 
agents,  contractors,  and  other  partners)  will  comply  with  anti-bribery  laws.  When  working  with  third  parties,  we  are 
committed to working with only those who embrace high standards of ethical behavior consistent with our own. Bribery and 
corruption  risks  are  a  focus  of  our  third-party  diligence  and  management  process.  We  hold  our  suppliers  accountable  for 
meeting  their  contractual  obligations  with  ICON,  including  commitments  that  are  made  with  regard  to  our  Global  Supplier 
Code of Conduct and regulatory compliance. Contract non-compliance can result in termination of the business relationship 
with the supplier and exclusion from future business with ICON. 

ICON's  internal  audit  teams  conduct ABAC  Program  audits.  Internal Audit  focuses  on  testing  for  compliance  and  design 
effectiveness of the overall ABAC Program. Internal Audit incorporates an assessment of ABAC measures in all audits, as 
appropriate. In this approach, bribery and corruption risks are incorporated into the risk assessment and scoping process of 
each audit.

For further details on risks relating to anti-corruption refer to Appendix A.

Information Security and Privacy

Data privacy and information security are fundamental to our business and key to retaining customers, building investors’ 
trust, protecting patients, and complying with global and regional regulations. We recognize and respect that our customers, 
employees,  patients,  and  all  those  who  do  business  with  us  expect  that  we  will  protect  their  personal  information  in 
accordance with our legal obligations and policy commitments. 

Our cybersecurity strategy and program protect our systems and data from an evolving threat landscape. The cybersecurity 
program, overseen by the Chief Information Officer (CIO), has the support of executive leadership and the Board, and we 
have  invested  heavily  in  cybersecurity  technologies  to  protect  our  environment.  Our  processes  and  range  of  information 
security policies are certified to ISO 27001 and are independently audited twice annually. ICON also maintains the Cyber 
Essentials certification. During an acquisition process, we conduct security and privacy due diligence and risk assessments, 
implement policies, deliver employee training, and securely integrate IT systems.

Our  Global  Data  Protection  Policy  regulates  the  processing  of  personal  data  in  accordance  with  the  applicable  data 
protection  laws  of  the  countries  where  we  operate,  including  Europe’s  General  Data  Protection  Regulation  (GDPR) 
framework. This policy governs ICON’s and its employees’ obligations concerning the processing of personal data, including 
core privacy issues such as how we address data subject rights, data protection impact assessments and our obligations to 
maintain records of processing activities (ROPAs).

ICON has a separate Personal Data Incident and Breach Response Policy and Process that governs the management of 
personal  data  incidents  and  breaches  within  ICON.  The  policy  requires  incidents  to  be  reported  to  ICON’s  Global  Data 
Protection Officer (DPO) and Privacy Team, who manage them in collaboration with relevant internal stakeholders (e.g., IT 
Security,  Quality  &  Compliance),  to  ensure  we  comply  with  our  legal  and  contractual  obligations,  including  our  reporting 
obligations. Our privacy program is overseen by the CAO.

Our  people  and  partners  play  a  critical  role  in  safeguarding  data.  ICON  has  training  in  place  for  all  employees  and 
contingent workers on information security and privacy practices so that they understand their responsibilities with respect to 
data security and privacy.

For further details on risks relating to information security and privacy refer to Appendix A.

Sustainable procurement

ICON  maintains  policies  and  practices  to  support  responsible,  sustainable,  and  ethical  business  practices.  Our  goal  is  to 
source  from  suppliers  whose  values  align  with  our  own,  including  suppliers  who  are  committed  to  diversity  and  inclusion, 
and are socially and environmentally responsible and conscious.  

We  manage  our  suppliers  through  our  Global  Procurement  department.  The  onboarding  of  new  suppliers  is  completed 
through a centrally managed due diligence process. Environmental sustainability, bribery, and corruption risks are a focus of 
our collective third-party diligence and management process. We require our suppliers to abide by our Global Supplier Code 
of Conduct which incorporates the Pharmaceutical Supply Chain Initiative (PSCI) principles for Responsible Supply Chain 
Management and sets out our standards and expectations regarding:

•
•
•
•

Ethics and compliance
Labor and human rights
Health and safety
Environmental stewardship

ICON performs pre-engagement due diligence on our suppliers. This includes screening of sanctions lists, debarment, and 
adverse  media.  Suppliers  are  continuously  monitored  against  sanctions  and  debarment  lists  and  are  periodically  re-
screened.  Suppliers  deemed  higher  risk  are  subject  to  enhanced  due  diligence  and  controls,  which  may  include  periodic 
training, auditing, and assessments. 

We  hold  our  suppliers  accountable  for  meeting  their  contractual  obligations,  including  commitments  relating  to  our  Global 
Supplier  Code  of  Conduct  and  regulatory  compliance.  Contract  non-compliance  can  result  in  termination  of  the  business 
relationship and exclusion from future business with our company.    

We have also engaged with EcoVadis, CDP and Supplier IO to assess our key suppliers and allow us to take ESG status 
into our decision making on vendor selection. 

For further details on risks relating to sustainable procurement refer to Appendix A: Risk Factors.

Statement of Directors’ Responsibilities in respect of the Directors’ report and the 
financial statements

The  directors  are  responsible  for  preparing  the  annual  report  and  the  Group  and  Company  financial  statements  in 
accordance with applicable law and regulations.

Company  law  requires  the  directors  to  prepare  the  Group  and  Company  financial  statements  for  each  financial  year. The 
directors have elected to prepare the Group and Company financial statements in accordance with IFRS as adopted by the 
EU and as applied in accordance with the Companies Act.

Under company law the directors must not approve the Group and Company financial statements unless they are satisfied 
that  they  give  a  true  and  fair  view  of  the  assets,  liabilities  and  financial  position  of  the  Group  and  Company  and  of  the 
Group’s profit or loss for that year. In preparing the Group and Company financial statements, the directors are required to:

•

select suitable accounting policies and then apply them consistently;

• make judgements and estimates that are reasonable and prudent; 

•

•

•

state whether applicable Accounting Standards have been followed, subject to any material departures disclosed 
and explained in the financial statements;

assess the Group and Company’s ability to continue as a going concern, disclosing, as applicable, matters related 
to going concern; and

use the going concern basis of accounting unless they either intend to liquidate the Group or Company or to cease 
operations, or have no realistic alternative but to do so.

The directors are responsible for keeping adequate accounting records which disclose with reasonable accuracy at any 
time the assets, liabilities, financial position of the Group and Company and profit or loss of the Group and which enable 
them to ensure that the financial statements comply with the provision of the Companies Act. They are responsible for 
such internal controls as they determine are necessary to enable the preparation of financial statements that are free 
from material misstatement, whether due to fraud or error, and have a general responsibility for safeguarding the assets 
of the Company and the Group, and hence for taking reasonable steps for the prevention and detection of fraud and 
other  irregularities.  The  directors  are  also  responsible  for  preparing  a  directors’  report  that  complies  with  the 
requirements of the Companies Act.

The directors are responsible for the maintenance and integrity of the corporate and financial information included on 
the Company's website. Legislation in the Republic of Ireland governing the preparation and dissemination of financial 
statements may differ from legislation in other jurisdictions.

Independent Auditor’s Report to the members of ICON plc 

Report on the audit of the financial statements

Opinion

We have audited the financial statements of ICON plc (‘the Company’) and its consolidated undertakings  (together, “the 
Group”) for the year ended 31 December 2022, set out on pages 36 to 153, which comprise the Consolidated Statement of 
Profit and Loss, Consolidated Statement of Comprehensive Income, Consolidated Statement of Financial Position, 
Consolidated Statement of Changes in Equity, Consolidated Statement of Cash Flows, Company Statement of Financial 
Position, Company Statement of Changes in Equity, Company Statement of Cash Flows and related notes, including the 
summary of significant accounting policies set out in note 1 of the consolidated financial statements.

The financial reporting framework that has been applied in their preparation is Irish Law and International Financial 
Reporting Standards (IFRS) as adopted by the European Union and, as regards the Company financial statements, as 
applied in accordance with the provisions of the Companies Act 2014.

In our opinion:

•

•

•

•

the financial statements give a true and fair view of the assets, liabilities and financial position of the Group and the 
Company as at 31 December 2022 and of the Group profit for the year then ended;

the Group financial statements have been properly prepared in accordance with IFRS as adopted by the European 
Union; and

the Company financial statements have been properly prepared in accordance with IFRS as adopted by the 
European Union, as applied in accordance with the provisions of the Companies Act 2014; and

the Group and Company financial statements have been properly prepared in accordance with the requirements of 
the Companies Act 2014.

Basis for opinion

We conducted our audit in accordance with International Standards on Auditing (Ireland) (ISAs (Ireland)) and applicable law.  
Our responsibilities under those standards are further described in the Auditor's responsibilities for the audit of the financial 
statements section of our report.  We have fulfilled our ethical responsibilities under, and we remained independent of the 
Company in accordance with ethical requirements that are relevant to our audit of financial statements in Ireland, including 
the Ethical Standard issued by the Irish Auditing and Accounting Supervisory Authority (IAASA), as applied to listed entities.  

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Conclusions relating to going concern

In auditing the financial statements, we have concluded that the director's use of the going concern basis of accounting in 
the preparation of the financial statements is appropriate. Our evaluation of the director’s assessment of the entity’s ability to 
continue to adopt the going concern basis of accounting included.

•

•

•

•

•

agreeing the underlying cash flow projections to management approved forecasts, assessing how these forecasts 
are compiled, and assessing the accuracy of management’s forecasts; 

evaluating the key assumptions within management’s forecasts;

considering liquidity and available financial resources;

assessing whether the stress testing performed by management appropriately considered the principal risks facing 
the business; and

evaluating the feasibility of management’s mitigating actions in the stress testing scenarios.                                                                                                                                                                                                                                                     

Based on the work we have performed, we have not identified any material uncertainties relating to events  or conditions 
that, individually or collectively, may cast significant doubt on the Group’s or the Company’s ability to continue as a going 
concern for a period of at least twelve months from the date when the financial statements are authorised for issue.  

Our  responsibilities  and  the  responsibilities  of  the  directors  with  respect  to  going  concern  are  described  in  the  relevant 
sections of this report.

29

Independent Auditor’s Report to the members of ICON plc (continued)

Detecting irregularities including fraud

We identified the areas of laws and regulations that could reasonably be expected to have a material effect on the financial 
statements and risks of material misstatement due to fraud, using our understanding of the entity's industry, regulatory 
environment and other external factors and inquiry with the directors.  In addition, our risk assessment procedures included:

•

•

•

•

•

•

Inquiring  with  the  directors  as  to  the  Group’s  policies  and  procedures  regarding  compliance  with  laws  and 
regulations,  identifying,  evaluating  and  accounting  for  litigation  and  claims,  as  well  as  whether  they  have 
knowledge of non-compliance or instances of litigation or claims.

Inquiring  of  directors  as  to  the  Group’s  policies  and  procedures  to  prevent  and  detect  fraud,  as  well  as  whether 
they have knowledge of any actual, suspected or alleged fraud.

Inquiring of directors and the audit committee, regarding their assessment of the risk that the financial statements 
may be materially misstated due to irregularities, including fraud.

Inspecting the Group’s regulatory and legal correspondence.

Reading Board and audit committee meeting minutes.

Performing planning analytical procedures to identify any usual or unexpected relationships.

We discussed identified laws and regulations, fraud risk factors and the need to remain alert among the audit team. This 
included communication from the group to component audit teams of relevant laws and regulations and any fraud risks 
identified at the Group level and request to component audit teams to report to the Group audit team any instances of fraud 
that could give rise to a material misstatement at group.

Firstly, the Group is subject to laws and regulations that directly affect the financial statements including companies and 
financial reporting legislation. We assessed the extent of compliance with these laws and regulations as part of our 
procedures on the related financial statement items, including assessing the financial statement disclosures and agreeing 
them to supporting documentation when necessary.

Secondly, the Group is subject to many other laws and regulations where the consequences of non-compliance could have 
a material effect on amounts or disclosures in the financial statements, for instance through the imposition of fines or 
litigation. We identified the following areas as those most likely to have such an effect: health and safety, anti-bribery, 
employment law, environmental law, regulatory capital and liquidity.

Auditing standards limit the required audit procedures to identify non-compliance with these non-direct laws and regulations 
to inquiry of the directors and inspection of regulatory and legal correspondence, if any. These limited procedures did not 
identify actual or suspected non-compliance.

We assessed events or conditions that could indicate an incentive or pressure to commit fraud or provide an opportunity to 
commit fraud. As required by auditing standards, we performed procedures to address the risk of management override of 
controls and the risk of fraudulent revenue recognition. We identified a fraud risk in relation to the Group and Component 
clinical trial service revenue, being the contract realizable value.

In response to the fraud risks, we also performed procedures including:

•

•

•

Identifying  journal  entries  to  test  based  on  risk  criteria  and  comparing  the  identified  entries  to  supporting 
documentation.

Assessing significant accounting estimates for bias.

Assessing the disclosures in the financial statements.

As the Group is regulated, our assessment of risks involved obtaining an understanding of the legal and regulatory 
framework that the Group operates and gaining an understanding of the control environment including the entity’s 
procedures for complying with regulatory requirements.

Owing to the inherent limitations of an audit, there is an unavoidable risk that we may not have detected some material 
misstatements in the financial statements, even though we have properly planned and performed our audit in accordance 
with auditing standards. For example, the further removed non-compliance with laws and regulations (irregularities) is from 
the events and transactions reflected in the financial statements, the less likely the inherently limited procedures required by 
auditing standards would identify it.

30

Independent Auditor’s Report to the members of ICON plc (continued)

In addition, as with any audit, there remains a higher risk of non-detection of irregularities, as these may involve collusion, 
forgery, intentional omissions, misrepresentations, or the override of internal controls. We are not responsible for preventing 
non-compliance and cannot be expected to detect non-compliance with all laws and regulations.

Key audit matters: our assessment of risks of material misstatement

Key audit matters are those matters that, in our professional judgement, were of most significance in the audit of the 
financial statements and include the most significant assessed risks of material misstatement (whether or not due to fraud) 
identified by us, including those which had the greatest effect on: the overall audit strategy; the allocation of resources in the 
audit; and directing the efforts of the engagement team.  These matters were addressed in the context of our audit of the 
financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these 
matters.

In arriving at our audit opinion above, the key audit matters were as follows:

(We continue to perform procedures over the valuation of the customer relationship intangible asset.  However, we have not 
assessed this as one of the most significant risks in our current year audit and, therefore, it is not separately identified in our 
report this year.)

Independent Auditor’s Report to the members of ICON plc (continued)

The key audit matter

How the matter was addressed in our audit

As discussed in Note 3 to the 
consolidated financial statements, 
the Company recognized revenue 
of US$7,734 million for the year 
ended 31 December 2022, a 
portion of which relates to clinical 
trial service revenue. As discussed 
in Note 2 to the consolidated 
financial statements, clinical trial 
service revenue is recognized over 
time, using an input measure, 
being total project costs (inclusive 
of third-party costs, principally 
pass-through/ reimbursable 
expenses) incurred at each 
reporting period as a percentage of 
forecasted total project costs, to 
measure progress towards 
satisfying the Company’s 
performance obligation. The 
transaction price is based on the 
contract or latest change order 
value, adjusted to reflect the 
estimated realizable contract 
value.

We identified the evaluation of 
revenue recognition for clinical trial 
service revenue as a key audit 
matter. Complex and subjective 
auditor judgment was required to 
evaluate the Company’s estimate 
of total forecast project costs and 
the estimated realizable contract 
values.

Our audit procedures included:

• We evaluated the design and tested the operating effectiveness of certain 

internal controls related to the revenue process, including controls over total 
forecast project costs and estimated realizable contract values.

• We tested the total forecast project costs and the realizable contract values 

for a selection of clinical trial service contracts, by evaluating:

•

•

•

•

•

direct costs incurred, both during the year and cumulative over the 
life of the contracts. We tested the accuracy and completeness of 
the direct costs by comparing the amounts to source data

third-party costs incurred, both during the year and cumulative over 
the life of the contracts. We tested the accuracy and completeness 
of the third-party costs incurred by comparing the costs to invoices 
received

findings from interviews with operational personnel of the Company 
to assess progress to date, the estimate of remaining costs to be 
incurred and factors impacting the amount of time and costs to 
complete the selected contracts, including an understanding of the 
nature and complexity of the work to be performed

correspondence of amendments to the scope or contract value, if 
any, between the Company and the customer for the selected 
contracts as part of our evaluation of contract progress —quarterly 
movements in forecast project costs and project margins and 
investigating the reasons for those movements, an

the reasonableness of the Company’s adjustments from total 
contract value to arrive at realizable contract value. We confirmed 
total contract value with customers and compared the assumptions 
used to derive the adjustments from total contract value to realizable 
contract value to underlying records.

• We also evaluated the Company’s methods, assumptions and data used to 
accurately estimate total forecast project costs and realizable contract 
values, by comparing historical estimates developed at contract inception to 
actual results for a selection of clinical trial service contracts.

We found that the estimates and judgements used in determining the progress 
towards completion and realisable contract value related to revenue recognition for 
clinical trial services contracts were appropriate.

Independent Auditor’s Report to the members of ICON plc (continued)

The key audit matter

How the matter was addressed in our audit

Our audit procedures included:

• We compared the carrying value of investments in the Company's 

Balance Sheet to the net assets of the subsidiary financial statements/

• We compared the carrying value of subsidiaries to the market 

capitalisation of the Company at December 31, 2022.

Based on evidence obtained, we found management's assessment of the key 
assumptions used in assessing the carrying value of investments in subsidiary 
undertakings to be appropriate.

The carrying amount of the Company's 
investments in subsidiary undertakings 
represents 97.8% (2021: 96.1%) of the 
Company's total assets. 

The investment in subsidiary 
undertakings is carried in the balance 
sheet of the Company at cost less 
impairment.  At December 31, 2022, the 
investment carrying value was $7,086.4 
million.

There is a significant risk in respect of 
the carrying value of these investments 
if the future cash flows and trading 
performance of these subsidiaries are 
not sufficient to support the balance 
sheet value.

Our application of materiality and an overview of the scope of our audit  

Materiality for the Group financial statements as a whole was set at US$30.0 million (2021: US$30.0 million), determined 
with reference to a benchmark of expected Group profit before tax (this estimated amount was based on earnings guidance 
available at the planning stage of the audit adjusted for exceptional items) (of which it represents 4.76% (2021: 6.62%).  
Due to the nature of the group, group profit before tax is the most relevant metric to the users of the financial statements in 
assessing the financial performance of the Group.

With respect to the Company, we based our calculation of materiality on total assets due to its nature as a holding company.  
As the calculated materiality was higher than Group materiality, we restricted our materiality to US$30.0 million (2021: 
US$70.0 million).

Performance materiality for the Group financial statements and Company financial statements as a whole was set at 
US$22.5m (2021: US$22.5m) and US$22.5m (2021: US$52.5m) respectively, determined with reference to benchmarks of 
expected Group profit before tax for the Group and total assets for the Company ((of which it represents 3.57% (2021: 
4.96%) and 0.31% (2021: 0.75%) respectively).  We applied this percentage in our determination of performance materiality 
based on the level of identified control deficiencies during the prior period.

We reported to the Audit Committee any corrected or uncorrected identified misstatements exceeding US$1.5m (2021: 
US$1.5m), in addition to other identified misstatements that warranted reporting on qualitative grounds.  Our audit was 
undertaken to the materiality and performance materiality level specified above and we applied materiality to assist us 
determine what risks were significant risks and the procedures to be performed.

The structure of the Group’s finance function is such that the majority of transactions and balances are accounted for by the 
central Group finance team. We performed comprehensive audit procedures, including those in relation to the significant risk 
set out above, on those transactions accounted for at Group level. Our audit covered 96% of total Group revenue and 95% 
of total Group assets, including 100% of the Company’s revenue and total assets.

We identified 4 (2021: 3) components in the scope of our audit, we subjected 1 (2021:2) to full scope audits for group 
purposes and 1 to specified risk-focused audit procedures. The latter was not individually financially significant enough to 
require a full scope audit for group purposes, but did present specific individual risks that needed to be addressed. We 
instructed the component auditor as to the significant areas to be covered, including the relevant risks detailed above and 
the information to be reported back.

Other information

The directors are responsible for the other information presented in the Annual Report together with the financial 
statements. The other information comprises the information included in the directors’ report. The financial statements and 
our auditor’s report thereon do not comprise part of the other information. Our opinion on the financial statements does not 
cover the other information and, accordingly, we do not express an audit opinion or, except as explicitly stated below, any 
form of assurance conclusion thereon.

Independent Auditor’s Report to the members of ICON plc (continued)

Our responsibility is to read the other information and, in doing so, consider whether, based on our financial statements 
audit work, the information therein is materially misstated or inconsistent with the financial statements or our audit 
knowledge. Based solely on that work we have not identified material misstatements in the other information.
Based solely on our work on the other information, we report that:

•

•

•

we have not identified material misstatements in the directors’ report;

in our opinion, the information given in the directors’ report is consistent with the financial statements;

in our opinion, the directors’ report has been prepared in accordance with the Companies Act 2014.  

Our opinions on other matters prescribed by the Companies Act 2014 are unmodified

We have obtained all the information and explanations which we consider necessary for the purpose of our audit.

 In our opinion, the accounting records of the Company were sufficient to permit the financial statements to be readily and 
properly audited and the Company’s financial statements are in agreement with the accounting records.  

We have nothing to report on other matters on which we are required to report by exception

The Companies Act 2014 requires us to report to you if, in our opinion, the disclosures of directors’ remuneration and 
transactions required by Sections 305 to 312 of the Act are not made. We have nothing to report in this regard.

The Companies Act 2014 also requires us to report to you if, in our opinion, the Company has not provided the information 
required by section 5(2) to (7) of the European Union (Disclosure of Non-Financial and Diversity Information by certain large 
undertakings and groups) Regulations 2017 for the year ended 31 December 2021 as required by the European Union 
(Disclosure of Non-Financial and Diversity Information by certain large undertakings and groups) (amendment) Regulations 
2018. We have nothing to report in this regard.

Respective responsibilities and restrictions on use

Responsibilities of directors for the financial statements

As explained more fully in their statement set out on page 28, the directors are responsible for: the preparation of the 
financial statements including being satisfied that they give a true and fair view; such internal control as they determine is 
necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud 
or error; assessing the Group and Company’s ability to continue as a going concern, disclosing, as applicable, matters 
related to going concern; and using the going concern basis of accounting unless they either intend to liquidate the Group or 
the Company or to cease operations, or have no realistic alternative but to do so.

Auditor’s responsibilities for the audit of the financial statements

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material 
misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion.  Reasonable 
assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs (Ireland) will 
always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered 
material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users 
taken on the basis of these financial statements.  

A fuller description of our responsibilities is provided on IAASA’s website at 
https://iaasa.ie/publications/description-of-the-auditors-responsibilities-for-the-audit-of-the-financial-statements/

Notes to Consolidated Financial Statements 
for the year ended 31 December 2022

1.  Basis of preparation and statement of accounting policies

Statement of compliance

The  Group  Financial  Statements  have  been  prepared  in  accordance  with  International  Financial  Reporting  Standards 
("IFRS") issued by the International Accounting Standards Board (“IASB”) as adopted by the European Union ("EU") that are 
effective for financial year ending 31 December 2022, and with those parts of the Companies Act applicable to companies 
reporting under IFRS. The Company Financial Statements have been prepared in accordance with IFRS as adopted by the 
EU, as applied in accordance with the Companies Act applicable to companies reporting under IFRS. IFRS adopted by the 
EU differs in certain respects from IFRS issued by the IASB. Reference to IFRS hereafter refers to IFRS adopted by the EU. 
A Company that publishes its Group and Company Financial Statements together can take advantage of the exemption in 
Section 304 of the Companies Act from presenting to its members a Company Statement of Profit and Loss and Company 
Statement of Comprehensive Income and related notes.  

Basis of preparation 

The  Group  and  Company  Financial  Statements  are  presented  in  United  States  dollars  ("U.S.  dollars")  and  all  values  are 
rounded to the nearest thousand ($‘000), except where otherwise indicated. They are prepared on the historical cost basis, 
except  for  the  measurement  at  fair  value  on  date  of  grant  of  share  options,  the  pension  plan  assets,  derivative  financial 
instruments, other investments and financial assets. Other than the amended standards adopted by the Group, accounting 
policies  are  applied  consistently  with  the  prior  year.  Certain  comparative  financial  information  has  been  revised  to  reflect 
measurement period adjustments, in accordance with IFRS 3 Business Combinations (refer to note 14 for further details). 

New standards and interpretations

The  following  standards  and  interpretations  became  effective  for  the  Group  during  the  financial  year  but  do  not  have  a 
material effect on the results or financial position of the Group:

a. Amendments to IAS 16 Property, Plant and Equipment (PPE): Proceeds before Intended Use
b. Amendments to IAS 37 Provisions, Contingent Liabilities and Contingent Assets: Costs to Fulfill a Contract
c. Amendments to IFRS 3 Business Combinations
a. Amendments to IAS 1 Classification of Liabilities as Current or Non-current and Disclosure of Accounting Policies 

The following standards and interpretations are not yet effective for the Group and are not expected to have a material effect 
on the results or financial position of the Group:

a. Amendments to IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors (Effective date: 1 January 

2023)

b. Amendments to IAS 12 Income Taxes (Effective date: 1 January 2023)
c. Amendments to IFRS 17 Insurance Contracts (Effective date: 1 January 2023)
d. Amendments to IFRS 16 Leases (Effective date: 1 January 2024)

Critical accounting judgements and key sources of estimation uncertainty

The preparation of consolidated financial statements requires management to make estimates and judgments that affect the 
reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and 
expenses during the reported period. 

We  base  our  estimates  and  judgments  on  historical  experience  and  on  the  other  factors  that  we  believe  are  reasonable 
under current circumstances. Actual results may differ from these estimates if these assumptions prove to be incorrect or if 
conditions  develop  other  than  as  assumed  for  the  purposes  of  such  estimates.  The  following  is  a  discussion  of  the 
accounting policies used by us, which we believe are critical in that they require estimates and judgements by management. 
The  application  of  these  critical  accounting  policies  and  estimates  is  discussed  with  the Audit  Committee  of  the  Board  of 
Directors.

1.  Basis of preparation and statement of accounting policies (continued)

Revenue recognition

Significant management judgments and estimates must be made and used in connection with the recognition of revenue in 
any accounting period. Material differences in the amount of revenue in any given period may result if these judgments or 
estimates prove to be incorrect or if management’s estimates change on the basis of development of the business or market 
conditions. To date there have been no material differences arising from these judgments and estimates.We earn revenues 
by  providing  a  number  of  different  services  to  our  clients.  These  services,  which  are  integral  elements  of  the  clinical 
development process, include clinical trials management, contract staffing, consulting and laboratory services. The criteria 
for  revenue  recognition  is  based  on  five  steps:  (1)  identify  the  contract(s)  with  a  customer;  (2)  identify  the  performance 
obligation  in  the  contract;  (3)  determine  the  transaction  price;  (4)  allocate  the  transaction  price  to  the  performance 
obligations in the contract; and (5) recognise revenue when (or as) the entity satisfies the performance obligation.

Clinical  trial  services  are  a  single  performance  obligation  satisfied  over  time  i.e.  the  full-service  obligation  in  respect  of  a 
clinical  trial  (including  those  services  performed  by  investigators  and  other  parties)  is  considered  a  single  performance 
obligation.  Promises  offered  to  the  customer  are  not  distinct  within  the  context  of  the  contract.  We  have  concluded  that 
ICON  is  the  contract  principal  in  respect  of  both  direct  services  and  in  the  use  of  third  parties  (principally  investigator 
services)  that  support  the  clinical  research  project.  The  transaction  price  is  determined  by  reference  to  the  contract  or 
change  order  value  (total  service  revenue  and  pass-through/  reimbursable  expenses)  adjusted  to  reflect  a  realisable 
contract value. An assessment of the realisable contract value is judgmental in nature. The realisable value assessment is 
updated at each reporting period, having regard to (i) contract terms and (ii) customer experience.  

Revenue  is  recognised  on  a  percentage  completion  basis  as  the  single  performance  obligation  is  satisfied. The  progress 
towards completion for clinical service contracts is measured therefore based on an input measure being total project costs 
(inclusive of third party costs) at each reporting period. Measurement of the progress towards completion involves judgment 
and estimation.  Assessment of completion requires an evaluation of labour and related time cost incurred at the reporting 
date  and  third  party  costs  incurred  at  the  reporting  date.  The  assessment  of  third  party  costs  incurred  (principally 
investigator costs) requires a review of activity performed and recorded by the third party services providers. The timing of 
payments  to  third  parties  in  respect  of  cost  incurred  reflect  invoicing  by  third  parties.  The  timing  difference  between  the 
activity performed and receipt of invoices from third parties may result in significant accrued amounts at reporting periods.  

The assessment of progress towards completion also requires an up to date evaluation of the forecast costs to complete in 
respect of these projects. Given the long-term nature of the clinical trials, and the complex nature of those trials, the forecast 
costs  to  complete  (being  internal  direct  costs  and  costs  that  will  be  incurred  by  third  parties  (principally  investigators))  is 
judgmental.  Forecast  time  (and  related  costs)  is  determined  by  reference  to  (i)  contract  terms  and  (ii)  past  experience. 
Forecast third party costs to complete are determined by project by reference to (i) contract terms and (ii) past experience. 

The  Company  provides  data  services  to  customers  based  on  agreed-upon  specifications,  including  the  timing  of  delivery, 
which is typically either weekly, monthly, or quarterly. If a customer requests more than one type of data report or series of 
data reports within a contract, each distinct type of data report is a separate performance obligation. The contracts provide 
for the Company to be compensated for the value of each deliverable. The transaction price is determined using list prices, 
discount agreements, if any, and negotiations with the customers, and generally includes any out-of-pocket expenses. 

The Company enters into contracts with some of its larger data suppliers that involve non-monetary terms. The Company 
issues purchase credits to be used toward the data supplier's purchase of the Company's services based on the fair value of 
the data obtained. In exchange, the Company receives monetary discounts on the data received from the data suppliers. 
The  fair  value  of  the  revenue  earned  from  the  customer  purchases  is  recognised  as  services  are  delivered  as  described 
above. At the end of the contract year, any unused customer purchase credits may be forfeited or carried over to the next 
contract  year  based  on  the  terms  of  the  data  supplier  contract.  The  calculation  of  the  fair  value  of  certain  non-monetary 
terms involves management judgement and estimation.

Intangible assets acquired in a business combination

Significant management judgments and estimates must be made and used in connection with the recognition of intangible 
assets associated with a business combination. The cost of a business combination is measured as the aggregate of the fair 
values at the date of exchange of assets given, liabilities incurred or assumed and equity instruments issued in exchange for 
control. The assets, liabilities and contingent liabilities of businesses acquired are generally measured at their fair values at 
the date of acquisition. When the initial accounting for a business combination is determined provisionally, any subsequent 
adjustments to the provisional values allocated to the identifiable assets, liabilities and contingent liabilities are made within 
twelve  months  of  the  acquisition  date  and  presented  as  adjustments  to  goodwill  in  the  reporting  period  in  which  the 
adjustments are determined.

Measurement of intangible assets involves the use of estimates for determining the fair value at the acquisition date.  The 
determination  of  the  fair  values  of  assets  and  liabilities,  as  well  as  of  the  useful  lives  of  the  assets  is  based  on 

43

Notes to Consolidated Financial Statements (continued)

1.  Basis of preparation and statement of accounting policies (continued)

management’s judgment. The valuation of intangible assets required management to develop discounted cash flow models 
which required the use of reasonable and supportable inputs such as customer attrition data, discount rates developed from 
various weighted average cost of capital assumptions, growth rates, margin forecasting and assessment of useful lives (see 
note  13  -  Intangible  assets  -  goodwill  and  other).  Management  utilised  external  valuation  experts,  where  necessary,  to 
ensure the valuation process was sufficiently detailed and robust to develop reliable valuations.

Taxation 

Given the global nature of our business and the multiple taxing jurisdictions in which the Group operates, the determination 
of the Group’s provision for income taxes requires significant judgments and estimates, the ultimate tax outcome of which 
may not be certain. Although we believe our estimates are reasonable, the final outcome of these matters may be different 
than those reflected in our historical income tax provisions and accruals.

Taxable profit differs from net profit as reported in the Consolidated Statement of Profit and Loss because it excludes items 
of  income  or  expense  that  are  taxable  or  deductible  in  other  years  and  further  excludes  items  that  are  not  taxable  or 
deductible. The Group’s liability for income tax is calculated using rates that have been enacted or substantively enacted at 
the reporting date. Income tax is recognised in the Consolidated Statement of Profit and Loss except to the extent that  it 
relates to items recognised directly in equity.

Deferred income tax is provided, using the liability method, on all differences between the carrying amounts of assets and 
liabilities  for  financial  reporting  purposes  and  the  amounts  used  for  taxation  purposes  except  those  arising  from  non-
deductible goodwill or on initial recognition of an asset or liability which affects neither accounting nor taxable profit. 
Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the year when the asset is 
expected to be realised or the liability to be settled.

Recognition of deferred tax assets is based on management’s belief that it is more likely than not that the income tax benefit 
associated with certain temporary differences, income tax operating loss, capital loss carryforwards, and income tax credits, 
would be realised. The carrying amount of deferred income tax assets is reviewed at each reporting date and reduced to the 
extent that it is no longer probable that sufficient taxable profit would be available to allow all or part of the deferred income 
tax asset to be utilised. The Group accounts for the impact of GILTI (“global intangible low-taxed income”) in the period it 
arises and therefore have not provided for deferred taxes in respect of this item. The Group recognises the effect of income 
tax  positions  only  if  those  positions  will  more  likely  than  not  be  sustained.  If  the  estimate  of  future  taxable  income  or  tax 
strategies  changes  at  any  time  in  the  future,  the  Group  would  record  an  adjustment  to  the  deferred  tax  asset.  Recording 
such an adjustment could have a material effect on the Group's financial condition or results of operations.

Accounting policies

The  following  accounting  policies  have  been  applied  consistently  in  dealing  with  items  which  are  considered  material  in 
relation to the Group’s Financial Statements.

Basis of consolidation 

The  Group’s  Financial  Statements  consolidate  the  financial  statements  of  ICON  plc  and  its  subsidiaries.  Subsidiaries  are 
consolidated from the date on which control is transferred to the Group and cease to be consolidated from the date on which 
control is transferred out of the Group. The Group controls an entity when it is exposed to, or has rights to, variable returns 
from  its  involvement  with  the  entity  and  has  the  ability  to  affect  those  returns  through  its  power  over  the  entity.  Financial 
statements of subsidiaries are prepared for the same reporting year as the Company and where necessary, adjustments are 
made to the results of subsidiaries to bring their accounting policies into line with those used by the Group. The Group will 
continue  to  prepare  the  individual  statutory  financial  statements  of  subsidiary  companies  under  GAAP  applicable  in  their 
country of incorporation but adjustments have been made to the results and financial position of such companies to bring 
their accounting policies into line with those of the Group.    

All  intercompany  balances  and  transactions,  including  unrealised  profits  arising  from  inter-group  transactions,  have  been 
eliminated in full. Unrealised losses are eliminated in the same manner as unrealised gains except to the extent that there is 
evidence of impairment.  

Foreign currency translation 

The presentation and functional currency of the Company is US dollars ($). The presentation currency of the Group is US 
dollars ($). The determination of the USD as the functional currency of the Company reflects consideration of the primary 
and  secondary  indicators  as  set  out  in  IAS  21.  The  directors  considered  in  particular  the  currency  in  which  funds  from 
financing activities are generated (debt and equity) and the currency in which receipts from operating activities are usually 
retained. This  assessment  is  consistent  with  the  assessment  that  the  functional  currencies  of  the  main  subsidiary  trading 

44

Notes to Consolidated Financial Statements (continued)

1.  Basis of preparation and statement of accounting policies (continued)

entities  are  USD.  The  Company  Financial  Statements  are  presented  in  US  dollars.  Results  and  cash  flows  of  non-dollar 
denominated  undertakings  are  translated  into  dollars  at  the  actual  exchange  rates  at  the  transaction  dates  or  average 
exchange rates for the year where this is a reasonable approximation. 

The related statements of financial position are translated at the rates of exchange ruling at the reporting date. Goodwill and 
fair  value  adjustments  arising  on  acquisition  of  a  foreign  operation  are  regarded  as  assets  and  liabilities  of  the  foreign 
operation, are expressed in the functional currency of the foreign operation and are recorded at the exchange rate at the 
date of the transaction, and subsequently retranslated at the applicable closing rates. Adjustments arising on translation of 
the results of non-dollar undertakings at average rates, and on the restatement of the opening net assets at closing rates, 
are recorded in the translation reserve within equity.

Transactions in currencies different to the functional currencies of operations are recorded at the rate of exchange ruling at 
the  date  of  the  transaction.  Monetary  assets  and  liabilities  denominated  in  foreign  currencies  are  retranslated  into  the 
functional currency at the rate of exchange at the reporting date. All translation differences, with the exception of translation 
differences on long-term intercompany balances in the Consolidated Financial Statements where repayment is not foreseen, 
are recorded in the Consolidated Statement of Profit and Loss. Translation differences on long-term intercompany balances, 
in  the  Consolidated  Financial  Statements,  where  repayment  is  not  foreseen  are  recorded  within  other  comprehensive 
income in the Statement of Comprehensive Income.   

On disposal of a foreign operation, accumulated currency translation differences, together with any exchange differences on 
foreign  currency  borrowings  that  provide  a  hedge  of  the  net  investment  are  recognised  in  the  Consolidated  Statement  of 
Profit and Loss as part of the overall gain or loss on disposal.

Items of property, plant and equipment are stated at cost less accumulated depreciation and any provisions for impairment 
losses. Depreciation is calculated to write off the original cost of property, plant and equipment less its estimated residual 
value over its expected useful life on a straight line basis. Residual values and useful lives of property, plant and equipment 
are reviewed and adjusted if appropriate at each reporting date. At present it is estimated that all items of property, plant and 
equipment  have  no  residual  value.  The  estimated  useful  lives  applied  in  determining  the  charge  to  depreciation  are  as 
follows:

Buildings

Computer equipment

Office furniture and fixtures

Laboratory equipment

Motor vehicles

Leasehold improvements are amortised using the straight-line method over the estimated useful life of the asset or the lease 
term, whichever is shorter.

On disposal of property, plant and equipment the cost and related accumulated depreciation and impairments are removed 
from the financial statements and the net amount, less any proceeds, is taken to the Consolidated Statement of Profit and 
Loss. 

The  carrying  amounts  of  the  Group’s  property,  plant  and  equipment  are  reviewed  at  each  reporting  date  to  determine 
whether  there  is  any  indicator  of  impairment.  Where  such  an  indicator  exists  an  impairment  review  is  carried  out.  An 

45

impairment loss is recognised whenever the carrying amount of an asset or its cash generation unit exceeds its recoverable 
amount. Impairment losses are recognised in the Consolidated Statement of Profit and Loss.

Subsequent costs are included in an asset’s carrying amount or recognised as a separate asset, as appropriate, only when 
it is probable that future economic benefits associated with the item will flow to the Group and the cost of the replaced item 
can be measured reliably. All other repair and maintenance costs are charged to the Consolidated Statement of Profit and 
Loss during the financial period in which they are incurred. 

Right-of-use assets and lease liabilities 

ICON determines if an arrangement is a lease at inception and recognises the rights and obligations on the Consolidated 
Statements of Financial Position as right-of-use (ROU) assets with corresponding lease liabilities. 

The right-of-use assets comprise the initial measurement of the corresponding lease liability, plus lease payments made at 
or  before  the  commencement  day  and  any  initial  direct  costs,  less  any  lease  incentives  received. They  are  subsequently 
measured at cost less accumulated depreciation and impairment losses. Right-of-use assets are depreciated over the lease 
term. 

The  right-of-use  assets  are  presented  as  a  separate  line  in  the  Consolidated  Statement  of  Financial  Position. The  Group 
applies  IAS  36  to  determine  whether  a  right-of-use  asset  is  impaired  and  accounts  for  any  identified  impairment  loss  as 
described in the ‘Property, Plant and Equipment’ policy.

Lease  liabilities  are  recognised  based  on  the  present  value  of  future  minimum  lease  payments  over  the  lease  term  at 
commencement date or date of transition with the interest element of the finance lease charged to financing expense. As 
most of ICON's leases do not provide an implicit rate, the discount rate used is based on the Group's incremental borrowing 
rate derived from the rate of traded corporate bonds available at the commencement date adjusted for country risk, liquidity 
and lease term.

Current lease liabilities are included in accrued and other liabilities in the Consolidated Statement of Financial Position and 
non-current lease liabilities are presented as a separate line. The lease liability is subsequently measured by increasing the 
carrying  amount  to  reflect  interest  on  the  lease  liability  (using  the  effective  interest  method)  and  by  reducing  the  carrying 
amount to reflect the lease payments made.

Lease  terms  may  also  include  options  to  extend  or  terminate.  Such  options  are  actively  reviewed  and  adjustments  to  the 
ROU asset and lease liability are made when it is reasonably certain the option will be exercised. 

Amendments  to  IFRS  16  were  made  by  the  IASB  in  2020  allowing  rent  concessions  directly  related  to  the  COVID-19 
pandemic not to be accounted as lease modifications. Rental concessions directly related to the COVID-19 pandemic are 
recognised in the Consolidated Statement of Profit and Loss in the period they are received. 

The Group accounts for lease and non-lease components separately with the exception of motor vehicle leases for which 
lease  and  non-lease  components  are  accounted  as  a  single  lease  component.  Lease  components  are  reflected  in  the 
Consolidated  Statements  of  Financial  Position  and  non-lease  components  expensed  directly  to  the  Consolidated 
Statements of Profit and Loss. 

The Group has elected to account for short-term leases using the practical expedient. Instead of recognising a right-of-use 
asset and lease liability, the payments in relation to these are recognised as an expense in the Consolidated Statement of 
Profit and Loss on a straight-line basis over the lease term.

In some cases, ICON enters into sublease agreements and becomes both a lessee and a lessor for the same underlying 
asset.  When  the  Group  is  an  intermediate  lessor,  it  accounts  for  the  head  lease  and  the  sub-lease  as  two  separate 
contracts.  Subleases  are  accounted  for  in  the  same  way  as  other  leases.  The  sub-lease  is  classified  as  a  finance  or 
operating lease by reference to the right-of-use asset arising from the head lease.

Business combinations

Business  combinations  are  accounted  for  using  the  acquisition  method  when  control  is  transferred  to  the  Group.  The  
consideration transferred is measured at fair value, as are the identifiable assets acquired and liabilities assumed. Where a 
business combination agreement provides for an adjustment to the cost of the acquisition which is contingent upon future 
events, the amount of the estimated adjustment is recognised on the acquisition date at the acquisition date fair value of this 
contingent consideration. The accounting treatment of any changes to this estimate in subsequent periods will depend on 
the  classification  of  the  contingent  consideration.  If  the  contingent  consideration  is  classified  as  equity  it  shall  not  be  re-
measured and the settlement shall be accounted for within equity. If the contingent consideration is classified as a liability 

46

Notes to Consolidated Financial Statements (continued)
for the year ended 31 December 2022

1.  Basis of preparation and statement of accounting policies (continued)

any  adjustments  to  the  assessment  of  contingent  consideration  determined  as  at  acquisition  date  will  be  accounted  for 
through the Consolidated Statement of Profit and Loss, as the liability is measured at fair value at each reporting date.  

The  assets,  liabilities  and  contingent  liabilities  of  businesses  acquired  are  measured  at  their  fair  values  at  the  date  of 
acquisition. In the case of a business combination which is completed in stages, the fair values of the identifiable assets, 
liabilities and contingent liabilities are re-determined at the date of each transaction until control is obtained. When the initial 
accounting  for  a  business  combination  is  determined  provisionally,  any  subsequent  adjustments  to  the  provisional  values 
allocated to the identifiable assets, liabilities and contingent liabilities are made within twelve months of the acquisition date 
and presented as adjustments to the original acquisition accounting. Acquisition costs are expensed as incurred.

Goodwill

The Group measures goodwill at the acquisition date as the fair value of the consideration transferred plus the recognised 
amount of any non controlling interests in the acquiree, if the business combination is achieved in stages, the fair value of 
the  pre-existing  equity  interest  in  the  acquiree,  less  the  net  recognised  amount  (generally  fair  value)  of  the  identifiable 
assets  acquired  and  liabilities  assumed.  Goodwill  on  the  acquisition  of  subsidiaries  is  included  in  ‘intangible  assets  – 
goodwill and other’.

At  the  acquisition  date,  any  goodwill  acquired  is  allocated  to  the  cash-generating  units  expected  to  benefit  from  the 
combination's  synergies.  Impairment  is  determined  by  assessing  the  recoverable  amount  of  the  cash-generating  unit  to 
which the goodwill relates. Where goodwill forms part of a cash-generating unit and part of the operation within that unit is 
disposed of, the goodwill associated with the operation disposed of is included in the carrying amount of the operation when 
determining  the  gain  or  loss  on  disposal  of  the  operation.  Goodwill  disposed  of  in  this  circumstance  is  measured  on  the 
basis of the relative values of the operation disposed of and the proportion of the cash-generating unit retained.

Following initial recognition, goodwill is measured at cost less any accumulated impairment losses. Goodwill is reviewed for 
impairment  annually  or  more  frequently  if  events  or  changes  in  circumstances  indicate  that  the  carrying  value  may  be 
impaired.

Intangible assets 

Other intangible assets are stated at cost less accumulated amortisation and impairment losses. Useful lives of intangibles 
are reviewed and adjusted if appropriate at each reporting date. Amortisation is charged to the Consolidated Statement of 
Profit and Loss on a straight-line basis over the estimated useful lives of intangible assets, currently estimated as follows:

Computer software
Customer relationships
Order backlog
Tradenames
Technology asset 
Non-compete arrangements
Patient database

Impairment

Years
2-8
7-23
1-7
3-5
5-8
5
7

The Group assessed at the end of each reporting period whether there is objective evidence that a financial asset or group 
of financial assets is impaired. A financial asset or a group of financial assets is impaired and impairment losses are incurred 
only if there is objective evidence of impairment as a result of one or more events that occur after the initial recognition of 
the asset (a 'loss event') and that loss event (or events) has an impact on the estimated future cash flows of the financial 
asset or group of financial assets that can be reliably estimated.  

Impairment losses in respect of other non-financial assets, other than goodwill, are reversed if there has been a change in 
the estimates used to determine recoverable amount.  Impairment losses are reversed only to the extent that the carrying 
amount  of  the  asset  does  not  exceed  the  carrying  value  that  would  have  been  determined,  net  of  depreciation  or 
amortisation, if no impairment loss had been recognised.  Impairment losses in respect of goodwill are not reversed.

for the year ended 31 December 2022

1.  Basis of preparation and statement of accounting policies (continued)

Inventories

Inventories, which comprise laboratory inventories, are stated at the lower of cost and net realisable value. Cost is based on 
the  first-in,  first-out  principle  and  includes  all  expenditure  incurred  in  acquiring  the  inventories  and  bringing  them  to  their 
present location and condition. Cost in the case of raw materials comprises the purchase price and attributable costs, less 
trade discounts. Net realisable value is the estimated selling price in the ordinary course of business, less selling expenses.   

Accounts payable

Trade and other payables are presented as current liabilities unless payment is not due within 12 months after the reporting 
period. They are recognised initially at fair value and subsequently measured at amortised cost using the effective interest 
rate method.

Government grants

Government  grants  received  that  compensate  the  Group  for  the  cost  of  an  asset  are  recognised  in  the  Consolidated 
Statement of Financial Position initially as deferred income when there is reasonable assurance that it will be received and 
that the Group will comply with the conditions attaching to it. Such grants are recognised in the Consolidated Statement of 
Profit  and  Loss  over  the  useful  economic  life  of  the  asset  which  is  consistent  with  the  depreciation  policy  of  the  relevant 
asset.

Grants that compensate the Group for expenses incurred are recognised in the Consolidated Statement of Profit and Loss 
in the same periods in which the expenditure to which they relate is charged. 

Under grant agreements, amounts received may become repayable in full or in part should certain circumstances specified 
within the grant agreements occur, including downsizing by the Group, disposing of the related assets, ceasing to carry on 
its  business  or  the  appointment  of  a  receiver  over  any  of  its  assets.  The  Group  has  not  recognised  any  such  loss 
contingency having assessed as remote the likelihood of these events arising. 

Provisions

A  provision  is  recognised  in  the  Consolidated  Statement  of  Financial  Position  when  the  Group  has  a  present  or  legal  or 
constructive obligation as a result of a past event, and it is probable that an outflow of economic benefits will be required to 
settle  the  obligation.  If  the  effect  of  the  time  value  of  money  is  material,  provisions  are  determined  by  discounting  the 
expected future cash flows at a pre-tax rate that reflects the time value of money and, where appropriate, the risks specific 
to the liability. Where discounting is used, the increase in the provision due to the passage of time is recognised as a finance 
cost.  

A provision for restructuring is recognised when the Group has approved a detailed and formal restructuring plan, and the 
restructuring has either commenced or has been announced publicly. Future operating costs are not provided for.

Financial Instruments

The Group assesses the business models and contractual cash flows which apply to its financial assets and classified the 
assets into the appropriate IFRS 9 categories accordingly.

See details below.

 (a) 

Cash and cash equivalents 

48

Notes to Consolidated Financial Statements (continued)
for the year ended 31 December 2022

1.  Basis of preparation and statement of accounting policies (continued)

Cash and cash equivalents include cash and highly liquid investments with original maturities of three months or less and 
are stated at fair value on initial recognition followed by amortised cost, which approximates fair value. 

(b) 

Trade receivables 

The Group's financial assets measured at amortised cost, the most significant of which are trade receivables and unbilled 
receivables, are subject to IFRS 9's expected credit loss model. 

For trade receivables and unbilled revenue, the Group applies the simplified approach permitted by IFRS 9, which requires 
expected lifetime losses to be recognised from initial recognition of the receivables. See notes 16 and 26 for further details. 
The expected credit losses on these financial assets are estimated based on the Group’s historical credit loss experience, 
adjusted for factors that are specific to the debtors, general economic conditions and an assessment of both the current, as 
well as the forecast direction of conditions, at the reporting date.

The Group writes off a financial asset when there is information indicating that the debtor is in severe financial difficulty and 
there  is  no  realistic  prospect  of  recovery,  e.g.  when  the  debtor  has  been  placed  under  liquidation  or  has  entered  into 
bankruptcy  proceedings.  Financial  assets  written  off  may  still  be  subject  to  enforcement  activities  under  the  Group’s 
recovery procedures, taking into account legal advice where appropriate. Any recoveries made are recognised in profit or 
loss.

Accounts receivable
Where  the  Company  enters  into  an  agreement  to  sell  certain  portfolios  of  its  accounts  receivable  balances,  the  sale  is 
accounted for in accordance with IFRS 9. Agreements which result in true sales of the transferred receivables, as defined in 
IFRS 9, which occur when receivables are transferred without recourse to ICON, are excluded from amounts reported in the 
Consolidated Balance Sheet. Cash proceeds received from such sales are included in operating cash flows. The associated 
finance costs are presented as interest expense.

(c) 

Current asset investments and non-current financial assets  

The Group classifies its financial assets in the following measurement categories: 

•
•

those to be measured subsequently at fair value through OCI; and
those to be measured subsequently at fair value through profit or loss.

The  classification  depends  on  the  entity's  business  model  for  managing  financial  assets  and  the  contractual  terms  of  the 
cash flows.  

At initial recognition, the Group measures a financial asset at its fair value plus, in the case of a financial asset not at fair 
value  through  profit  or  loss  (FVPL),  transaction  costs  that  are  directly  attributable  to  the  acquisition  of  the  financial  asset. 
Transaction costs of financial assets carried at FVPL are expensed in profit or loss. 

For assets measured at fair value, gains and losses will either be recorded in profit or loss or OCI. For investments in equity 
instruments that are not held for trading, this will depend on whether the Group has made an irrevocable election at the time 
of initial recognition to account for the equity investment at fair value through other comprehensive income (FVOCI). 

The Group reclassifies debt investments when and only when its business model for managing those assets changes.  

Purchases  or  sales  of  financial  assets  are  recognised  on  trade  date,  the  date  the  Group  commits  to  purchase  or  sell  the 
asset. Financial assets are de-recognised when the rights to receive cash flows from the financial assets have expired or 
have been transferred and the group has transferred substantially all the risks and rewards of ownership.  

Subsequent  measurement  of  debt  instruments  depends  on  the  Group's  business  model  for  managing  the  asset  and  the 
cash flow characteristics of the asset.  

There are three measurement categories into which the Group classifies its financial instruments:

•

•

Amortised  cost:  Assets  that  are  held  for  collection  of  contractual  cash  flows  where  those  cash  flows  represent 
solely  payments  of  principal  and  interest  are  measured  at  amortised  cost.  Interest  income  from  these  financial 
assets  is  included  in  finance  income  using  the  effective  interest  rate  method.  Any  gain  or  loss  arising  on 
derecognition  is  recognised  directly  in  profit  or  loss  and  presented  in  other  gains/(losses)  together  with  foreign 
exchange gains and losses.  

FVOCI: Assets that are held for collection of contractual cash flows and for selling the financial assets, where the 
assets' cash flows represent solely payments of principal and interest, are measured at FVOCI. Movements in the 

49

Notes to Consolidated Financial Statements (continued)
for the year ended 31 December 2022

1.  Basis of preparation and statement of accounting policies (continued)

carrying amount are taken through OCI, except for the recognition of impairment losses. When the financial asset 
is derecognised, the cumulative gain or loss previously recognised in OCI is reclassified from equity to profit or loss 
and recognised in other gains/(losses). Interest income from these financial assets is included in finance income 
using the effective interest rate method.  

•

FVPL: Assets that do not meet the criteria for amortised cost or FVOCI are measured at FVPL. A gain or loss on a 
debt investment that is subsequently measured at FVPL is recognised in profit or loss. 

The Group assesses on a forward-looking basis the expected credit losses associated with its debt instruments carried at 
amortised  cost. The  impairment  methodology  applied  depends  on  whether  there  has  been  a  significant  increase  in  credit 
risk.  

(d) 

Interest bearing loans and borrowings 

Borrowings are initially recognised at fair value, net of transaction costs incurred. Borrowings are subsequently measured at 
amortised  cost.  Subsequent  to  initial  recognition,  current  and  non-current  interest  bearing  loans  and  borrowings  are 
measured at amortised cost with any difference between cost and redemption value being recognised in the Consolidated 
Statement  of  Profit  and  Loss  over  the  period  of  the  borrowings  on  an  effective  interest  rate  basis.  Fees  paid  on  the 
establishment of loan facilities are recognised as transaction costs of the loan to the extent that it is probable that some or 
all of the facility will be drawn down. In this case, the fee is deferred until draw down will occur. Where there is no evidence 
that it is probable that some or all of the facility will be drawn down, the fee is capitalised as a prepayment and amortised 
over the period of the facility to which it relates.  

Borrowings are classified as current liabilities unless the Group has an unconditional right to defer settlement of the liability 
for at least 12 months after the reporting date.

Borrowings are removed from the Consolidated Statement of Financial Position when the obligation specified in the contract 
is  discharged,  cancelled  or  expired.  The  difference  between  the  carrying  amount  of  a  financial  liability  that  has  been 
extinguished  or  transferred  to  another  party  and  the  consideration  paid,  including  any  non-cash  assets  transferred  or 
liabilities assumed, is recognised in profit or loss as other income or finance costs. 

(e) 

Derivative financial instruments and hedging

Derivatives  are  initially  recognised  at  fair  value  on  the  date  a  derivative  contract  is  entered  into  and  are  subsequently 
remeasured  to  their  fair  value  at  the  end  of  each  reporting  period.  The  accounting  for  subsequent  changes  in  fair  value 
depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the item being hedged. 

The Group designates certain derivatives as either: 

•
•

•

hedges of the fair value of recognised assets or liabilities or a firm commitment (fair value hedges)
hedges of a particular risk associated with the cash flows of recognised assets and liabilities and highly probable 
forecast transactions (cash flow hedges), or 
hedges of a net investment in a foreign operation (net investment hedges).  

At inception of the hedge relationship, the Group documents the economic relationship between hedging instruments and 
hedged items including whether changes in the cash flows of the hedging instruments are expected to offset changes in the 
cash  flows  of  hedged  items. The  Group  documents  its  risk  management  objective  and  strategy  for  undertaking  its  hedge 
transactions.  

The  fair  value  of  derivative  financial  instruments  designated  in  hedge  relationships  are  disclosed  in  note  26  –  Financial 
instruments. Movements in the hedging reserve in shareholders' equity are shown in shareholders' equity. The full fair value 
of  a  hedging  derivative  is  classified  as  a  non-current  asset  or  liability  when  the  remaining  maturity  of  the  hedged  item  is 
more than 12 months. It is classified as a current asset or liability when the remaining maturity of the hedged item is less 
than 12 months.   

Cash flow hedges that qualify for hedge accounting 

The  effective  portion  of  changes  in  the  fair  value  of  derivatives  that  are  designated  and  qualify  as  cash  flow  hedges  is 
recognised  in  the  cash  flow  hedge  reserve  within  equity. The  gain  or  loss  relating  to  the  ineffective  portion  is  recognised 
immediately in profit or loss, within other gains/(losses).  

50

Notes to Consolidated Financial Statements (continued)
for the year ended 31 December 2022

1.  Basis of preparation and statement of accounting policies (continued)

Gains or losses relating to the effective portion of the change in intrinsic value of the options are recognised in the cash flow 
hedge  reserve  within  equity.  The  changes  in  the  time  value  of  the  options  that  relate  to  the  hedged  item  are  recognised 
within OCI in the costs of hedging reserve within equity.  

When  a  hedging  instrument  expires  or  is  sold  or  terminated,  or  when  a  hedge  no  longer  meets  the  criteria  for  hedge 
accounting, any cumulative deferred gain or loss and deferred costs of hedging in equity at that time remains in equity until 
the forecast transaction occurs.  

Changes in the fair value of any derivative instrument that does not qualify for hedge accounting are recognised immediately 
in profit or loss.  

During the year ended 31 December 2022, the Group entered into two interest rate cap agreements ("2022 Caps") and an 
interest  rate  swap  agreement  ("2022  Swap")  to  limit  its  exposure  to  changes  in  the  variable  interest  rate  on  its  Senior 
Secured  Credit  Facilities.  The  interest  rate  caps  and  swap  are  accounted  for  as  cash  flow  hedges  and  were  considered 
effective hedges on application of the provisions of IFRS 9. The effective portion of the hedges is recorded as a movement 
within Other Reserves for the year ended 31 December 2022.

Put and call options in unconsolidated entities

On 24 July 2020, the Group entered into an agreement to jointly establish a new company, Oncacare, with a third-party. The 
Group owns 49% of the voting share capital with the majority third party owning the remaining 51% voting share capital. The 
majority investor has the right to sell the 51% majority voting share capital exclusively to the Group in a two and half year 
period, commencing 1 January 2023 and the Group also has the right to acquire the 51% majority voting share capital from 
1 August 2025. These option arrangements are derivative financial instruments which have been bifurcated and separately 
recorded from the equity host contract as Oncacare is not part of the Group. These option arrangements will be measured 
at their fair value at each reporting period with changes in the fair value of the financial instruments recorded through the 
Consolidated Statement of Profit and Loss. On April 20, 2023, The Company, ICON Clinical Research Limited, completed 
it's purchase of Oncacare.  See Note 31 Subsequent Events for further details.

(f) 

Investments in subsidiaries - Company

Investments in subsidiary undertakings are stated at cost less any accumulated impairment and are reviewed for impairment 
if there are indicators that the carrying value may not be recoverable.  

Intercompany  loans  receivable  and  payable  are  initially  recognised  at  fair  value.  These  are  subsequently  measured  at 
amortised cost, less any loss allowance, calculated on an expected credit loss basis. 

Share capital

Ordinary shares are classified as equity.  Incremental costs directly attributable to the issue of new shares or options are 
shown in equity as a deduction, net of tax, from the proceeds. 

Where  ordinary  shares  are  re-purchased  by  the  Company  they  are  cancelled  and  the  nominal  value  of  the  shares  is 
transferred to other undenominated capital within equity.

Equity Method Investments

The Company’s investments that are not consolidated are accounted for under the equity method if the Company exercises 
significant  influence  that  is  considered  to  be  greater  than  minor.  These  investments  are  classified  as  equity  method 
investments on the accompanying Consolidated Statements of Financial Position. The Company records its pro rata share 
of the earnings/losses of these investments in Share of equity method investments in the Consolidated Statements of Profit 
and  Loss.  The  Company  reviews  these  for  impairment  whenever  events  or  changes  in  circumstances  indicate  that  the 
carrying amounts may not be recoverable.

Employee benefits

(a) Pension and other post-employment benefits

Certain  companies  within  the  Group  operate  defined  contribution  pension  plans. A  defined  contribution  plan  is  a  pension 
plan  under  which  the  Group  pays  fixed  contributions  into  a  separate  entity.  The  Group  has  no  legal  or  constructive 
obligations to pay further contributions if the fund does not hold sufficient assets to pay all employees the benefits relating to 

51

Notes to Consolidated Financial Statements (continued)
for the year ended 31 December 2022

1.  Basis of preparation and statement of accounting policies (continued)

employee  service  in  the  current  and  prior  periods.  Contributions  to  defined  contribution  pension  plans  are  expensed  as 
incurred.

The  Group  operates  defined  benefit  pension  plans  for  certain  of  its  United  Kingdom  and  Swiss  employees  through 
subsidiary  companies. A  defined  benefit  plan  is  a  pension  plan  that  is  not  a  defined  contribution  plan.  Typically,  defined 
benefit plans define the amount of pension benefit that an employee will receive on retirement, usually dependent on one or 
more factors such as age, years of service and compensation. Obligations for contributions to defined benefit contribution 
pension plans are recognised as an expense in the Consolidated Statement of Profit and Loss as service is received from 
the relevant employees.

The Group’s net obligation in respect of the defined benefit pension plans is calculated separately by estimating the amount 
of  future  benefit  that  employees  have  earned  in  return  for  their  service  in  the  current  and  prior  periods.  This  benefit  is 
discounted to determine its present value, and the fair value of plan assets deducted. The discount rate used in respect of 
the  UK  scheme  is  the  yield  at  the  reporting  date  on  the  iBoxx  corporate  bond  over  15  years  plus  10  basis  points.  The 
discount rate used in respect of the Swiss schemes is determined by the Swiss corporate bond yields at the reporting date. 
The calculation is performed by a qualified actuary using the projected unit credit method. The net finance income/cost are 
recorded  in  operating  costs  in  the  Consolidated  Statement  of  Profit  and  Loss.  When  benefits  of  a  plan  are  improved,  the 
portion of the increased benefit relating to the past service by employees is recognised as an expense in the Consolidated 
Statement of Profit and Loss on a straight line basis over the average period until the benefits become vested. To the extent 
that the benefits vest immediately, the expense is recognised immediately in the Consolidated Statement of Profit and Loss. 

(b) Share-based payments

Share-based  payments  comprise  options  to  acquire  ordinary  shares  in  the  Company,  RSUs  and  PSUs  in  the  form  of 
ordinary share entitlements after a certain period of time. These are awarded to certain key employees and Directors of the 
Group based on service conditions such as term of employment and individual performance. The fair value of options, RSUs 
and  PSUs  granted  is  recognised  as  an  employee  expense  with  a  corresponding  increase  in  equity.  The  fair  value  is 
measured at grant date and spread over the period during which the Directors and other employees become unconditionally 
entitled to the options, RSUs or PSUs.  The fair value of options granted is measured using a binomial lattice model, taking 
into account the terms and conditions upon which the options were granted. The fair value of RSUs and PSUs is equal to 
the market price of a share at date of grant. The total amount to be expensed is determined by reference to the fair value of 
the options, RSUs or PSUs granted. The amount recognised as an expense is adjusted to reflect the actual number of share 
options, RSUs or PSUs that vest. 

Forfeitures  are  estimated  on  the  date  of  grant  and  revised  if  actual  or  expected  forfeiture  activity  differs  materially  from 
original estimates. 

Share-based  payment  expense  is  recognised  over  the  requisite  service  period  for  awards  of  equity  instruments  to 
employees based on the grant date fair value of those awards expected to ultimately vest.  

Replacement awards

In  connection  with  the  completion  of  the  Merger,  the  Company  issued  replacement  awards  to  the  holders  of  PRA  equity 
awards  on  1  July  2021.  An  exchange  of  share-based  compensation  awards  in  a  business  combination  is  treated  as  a 
modification  under  IFRS  2.  The  replacement  awards  and  the  original  acquiree  awards  are  measured  at  fair  value  at  the 
acquisition date and calculated using the fair-value-based measurement principles in IFRS 2. Amounts attributable to pre-
combination vesting are accounted for as part of the consideration transferred for the acquiree. Amounts attributable to post-
combination vesting are accounted for separate from the business combination and are recognised as compensation cost in 
the post-combination period.

(c) Share-based payments – Company

The Company operates a number of share-based payment plans the details of which are presented in note 11 Share-based 
Payments to the Consolidated Financial Statements. The share-based payment expense associated with the share-based 
payment plans is recognised by the entity which receives services in exchange for the share-based compensation. 

The  Statement  of  Profit  and  Loss  of  the  Company  is  charged  with  the  expense  related  to  the  services  received  by  the 
Company. The remaining portions of the share-based payments represent a contribution to Company’s subsidiaries and are 
added to the carrying amount of those investments. Under an agreement, with certain subsidiaries, on the date of exercise 
the Company is paid an amount equal to the fair value of the ordinary shares issued that is in excess of the award exercise 
price with such amount reducing the Company’s investment in its subsidiaries. The net effect of the grant date fair value of 
the Company’s share-based compensation to employees of the Company’s subsidiaries and recharges received from those

subsidiaries is presented as a movement in financial fixed assets (see note 3 Investment in subsidiaries, to the Company 
only financial statements).

Revenue Recognition

The Company primarily earns revenues by providing a number of different services to its customers. These services, which 
are integral elements of the clinical development process, include clinical trials management, consulting, contract staffing, 
data  services  and  laboratory  services.  These  services,  which  are  described  below,  can  be  purchased  collectively  or 
individually as part of a clinical trial contract. There is not significant variability in how economic factors affect these services. 
Contracts range in duration from a number of months to several years. 

Revenue Recognition - Clinical trial service revenue

Under IFRS 15, a clinical trial service is a single performance obligation satisfied over time i.e. the full service obligation in 
respect  of  a  clinical  trial  (including  those  services  performed  by  investigators  and  other  parties)  is  considered  a  single 
performance  obligation.  Promises  offered  to  the  customer  are  not  distinct  within  the  context  of  the  contract.  ICON  is  the 
contract  principal  in  respect  of  both  direct  services  and  in  the  use  of  third  parties  (principally  investigator  services)  that 
support the clinical research project. The transaction price is determined by reference to the contract or change order value 
(total service revenue and pass-through/reimbursable expenses) adjusted downwards to reflect a realisable contract value. 
Revenue is recognised as the single performance obligation is satisfied. The progress towards completion for clinical service 
contracts  is  measured  based  on  an  input  measure  being  project  costs  incurred  as  a  proportion  of  total  project  costs 
(inclusive of third-party costs) at each reporting period.

Revenue Recognition - Contracting services revenue

The  Company  has  availed  of  the  practical  expedient  which  results  in  recognition  of  revenue  on  a  right  to  invoice  basis. 
Application  of  the  practical  expedient  reflects  the  right  to  consideration  from  the  customer  in  an  amount  that  corresponds 
directly  with  the  value  to  the  customer  of  the  performance  completion  to  date.  This  reflects  hours  performed  by  contract 
staff. 

Revenue Recognition - Consulting services revenue

Consulting  services  contracts  represent  a  single  performance  obligation  satisfied  over  time.  The  transaction  price  is 
determined  by  reference  to  contract  or  change  order  value.  Revenue  is  recognised  as  the  performance  obligation  is 
satisfied. The progress towards completion for consulting contracts is measured based on total project inputs (time) at each 
reporting period as a percentage of forecasted total project inputs. 

Revenue Recognition - Laboratory services revenue

Revenue is recognised when, or as, obligations under the terms of a contract are satisfied, which occurs when control of the 
products  or  services  are  transferred  to  the  customer.  Revenue  for  laboratory  services  is  measured  as  the  amount  of 
consideration  we  expect  to  receive  in  exchange  for  transferring  products  or  services.  Where  contracts  with  customers 
contain  multiple  performance  obligations,  the  transaction  price  is  allocated  to  each  performance  obligation  based  on  the 
estimated relative selling price of the promised good or service. Service revenue is recognised over time as the services are 
delivered  to  the  customer  based  on  the  extent  of  progress  towards  completion  of  the  performance  obligation.  The 
determination of the methodology to measure progress requires judgement and is based on the nature of services provided. 
This requires an assessment of the transfer of value to the customer. The right to invoice measure of progress is generally 
related to rate per unit contracts, as the extent of progress towards completion is measured based on discrete service or 
time-based increments, such as samples tested or labour hours incurred. Revenue is recorded in the amount invoiced since 
those amounts corresponds to the value of the Company's performance and the transfer of value to the customer.

Revenue Recognition - Data services revenue

The Company provides data reports and analytics to customers based on agreed-upon specifications, including the timing of 
delivery, which is typically either weekly, monthly, or quarterly. If a customer requests more than one type of data report or 
series of data reports within a contract, each distinct type of data report is a separate performance obligation. The contracts 
provide for the Company to be compensated for the value of each deliverable. The transaction price is determined using list 
prices,  discount  agreements,  if  any,  and  negotiations  with  the  customers,  and  generally  includes  any  out-of-pocket 
expenses. Typically, the Company bills in advance of services being provided with the amount being recorded as unearned 
revenue.

When  multiple  performance  obligations  exist,  the  transaction  price  is  allocated  to  performance  obligations  on  a  relative 
standalone selling price basis. In cases where the Company contracts to provide a series of data reports, or in some cases 

53

 
Notes to Consolidated Financial Statements (continued)
for the year ended 31 December 2022

1.  Basis of preparation and statement of accounting policies (continued)

data,  the  Company  recognises  revenue  over  time  using  the  “units  delivered”  output  method  as  the  data  or  reports  are 
delivered.  Expense  reimbursements  are  recorded  to  revenue  as  the  expenses  are  incurred  as  they  relate  directly  to  the 
services performed.

Certain  arrangements  include  upfront  customisation  or  consultative  services  for  customers.  These  arrangements  often 
include  payments  based  on  the  achievement  of  certain  contractual  milestones.  Under  these  arrangements,  the  Company 
contracts  with  a  customer  to  carry  out  a  specific  study,  ultimately  resulting  in  delivery  of  a  custom  report  or  data  product. 
These  arrangements  are  a  single  performance  obligation  given  the  integrated  nature  of  the  service  being  provided.  The 
Company typically recognises revenue under these contracts over time, using an output-based measure, generally time
elapsed,  to  measure  progress  and  transfer  of  control  of  the  performance  obligation  to  the  customer.  Expense 
reimbursements are recorded to revenue as the expenses are incurred as they relate directly to the service performed.

The Company enters into contracts with some of its larger data suppliers that involve non-monetary terms. The Company 
issues purchase credits to be used toward the data supplier's purchase of the Company's services based on the fair value of 
the data obtained. In exchange, the Company receives monetary discounts on the data received from the data suppliers. 
The  fair  value  of  the  revenue  earned  from  the  customer  purchases  is  recognised  as  services  are  delivered  as  described 
above. At the end of the contract year, any unused customer purchase credits may be forfeited or carried over to the
next contract year based on the terms of the data supplier contract.

Commissions

Incremental costs of obtaining a contract are recognised as an asset on the Consolidated Statement of Financial Position in 
respect of those contracts that exceed one year. Where commission costs relate to contracts that are less than one year, the 
practical expedient is applied as the amortisation period of the asset which would arise on deferral would be one year  or 
less.

Reimbursable expenses

Reimbursable  expenses  comprise  investigator  payments  and  certain  other  costs  which  are  reimbursed  by  clients  under 
terms  specific  to  each  contract  to  the  investigators.  The  Company  includes  reimbursed  expenses  in  revenue  and  direct 
costs as the Company is primarily responsible for fulfilling the promise to provide the specified service, including integration 
of the related services into a combined output to the customer.

Direct costs

Direct  costs  consist  of  compensation,  associated  employee  benefits  and  share-based  payments  for  project-related 
employees and other direct project-related costs. 

Reimbursable  expenses  are  presented  within  direct  costs. This  presentation  is  to  align  the  presentation  of  costs  with  our 
assessment that our clinical trial service is a single performance obligation satisfied over time. Reimbursable expenses are 
recorded once the activity which forms the basis for the cost has occurred. Payments are made based on predetermined 
contractual arrangements. Timing of payments may differ from the timing of the expense.

Other operating expenses

Other  operating  expenses  consist  of  compensation,  associated  employee  benefits  and  share-based  payments  for  non-
project-related  employees  and  other  indirect  costs  associated  with  the  business.  Other  operating  expenses  also  include 
depreciation expense and the amortisation of intangible assets.

Exceptional items

The  Company  has  used  the  term  “exceptional”  to  describe  certain  items  which,  in  management’s  view,  warrant  separate 
disclosure  by  virtue  of  their  size  or  incidence,  or  due  to  the  fact  that  certain  gains  or  losses  are  determined  to  be  non-
recurring  in  nature.  Exceptional  items  may  include  restructuring,  transaction  and  integration-related  expenses,  significant 
impairments, and material changes in estimates. Also see the replacement awards accounting policy described above.

Transaction and integration-related expenses
Transaction and integration-related expenses are the incremental costs directly attributable to the completion and integration 
activities  associated  with  the  Group’s  recent  acquisitions.  The  costs  consist  of  investment  banking  fees,  advisory  costs, 
retention  agreements  with  employees,  contingent  consideration  valuation  adjustments  and  ongoing  integration  activities. 
The  Group  accounts  for  these  transaction  and  integration-related  costs  as  expenses  in  the  period  in  which  the  costs  are 
incurred and the services are received.

54

Restructuring
Restructuring  charges  reflect  certain  one-time  and  associated  unavoidable  costs  arising  from  reorganisation  programmes 
announced by Group management. These programmes generally result in asset impairments and workforce reductions in 
order to optimise the Group’s structure and facilitate improved long-term performance. Impairment charges are taken when 
the value-in-use of the asset is less than the asset’s carrying value. Workforce related charges are taken when an approved 
reorganisation programme is communicated to the relevant employee groups.

Research and development credits

Research and development credits are available to the Group under the tax laws in certain jurisdictions, based on qualifying 
research and development spend as defined under those tax laws. Research and development credits may be recognised 
as a reduction of income tax expense. However, certain tax jurisdictions provide refundable credits that are not wholly 
dependent on the Group's ongoing income tax status or income tax position. In these circumstances the benefit of these 
credits is not recorded as a reduction to income tax expense, but rather as a reduction of operating expenditure.

Financing income

Interest income is recognised in the Consolidated Statement of Profit and Loss as it accrues using the effective interest rate 
method and includes interest receivable on investments.

Financing expense

Financing  expense  comprises  interest  payable  on  borrowings  calculated  using  the  effective  interest  rate  method,  finance 
charges  on  leases,  foreign  exchange  gains  and  losses  on  bank  loans,  non-cash  finance  charges  in  respect  of  contingent 
consideration and gains and losses on hedging instruments that are recognised in the Consolidated Statement of Profit and 
Loss. 

Financing expense also includes fees paid on the establishment of loan facilities which are recognised as transaction costs 
of the loan to the extent that it is probable that some or all of the facility will be drawn down. These fees are deferred and 
recognised in the Statement of Financial Position and are then amortised to the Consolidated Statement of Profit and Loss 
over the term the facility is available to the Group. 

Income tax

Income tax expense in the Consolidated Statement of Profit and Loss represents the sum of income tax currently payable 
and deferred income tax.

Income tax currently payable is based on taxable profit for the year. Taxable profit differs from net profit as reported in the 
Consolidated Statement of Profit and Loss because it excludes items of income or expense that are taxable or deductible in 
other years and further excludes items that are not taxable or deductible. The Group’s liability for income tax is calculated 
using  rates  that  have  been  enacted  or  substantively  enacted  at  the  reporting  date.  Income  tax  is  recognised  in  the 
Consolidated Statement of Profit and Loss except to the extent that it relates to items recognised directly in equity.

Deferred income tax is provided, using the liability method, on all differences between the carrying amounts of assets and 
liabilities  for  financial  reporting  purposes  and  the  amounts  used  for  taxation  purposes  except  those  arising  from  non-
deductible goodwill or on initial recognition of an asset or liability which affects neither accounting nor taxable profit. 
Deferred  income  tax  assets  and  liabilities  are  measured  at  the  tax  rates  that  are  expected  to  apply  in  the  year  when  the 
asset is expected to be realised or the liability to be settled.

Deferred tax assets are recognised for all deductible differences, carry forward of unused tax credits and unused tax losses, 
to the extent that it is probable that taxable profit will be available against which the deductible temporary differences and 
the carry forward of unused tax credits and unused tax losses can be utilised. The carrying amount of deferred income tax 
assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit 
would be available to allow all or part of the deferred income tax asset to be utilised.

Earnings per ordinary share

Basic earnings per share is computed by dividing the profit for the financial year attributable to ordinary shareholders of the 
Company by the weighted average number of ordinary shares outstanding during the financial period. 

Diluted  net  income  per  ordinary  share  is  computed  by  adjusting  the  weighted  average  number  of  ordinary  shares 
outstanding  during  the  period  for  all  potentially  dilutive  ordinary  shares  outstanding  during  the  period  and  adjusting  net 
income for any changes in income or loss that would result from the conversion of such potential ordinary shares. There is 
no difference in net income used for basic and diluted net income per ordinary share. 

Segment reporting

An operating segment is a component of the Group that engages in business activities from which it may earn revenues and 
incur expenses, including revenues and expenses that relate to transactions with any of the Group’s other components. The 
Group  determines  and  presents  operating  segments  based  on  the  information  that  internally  is  provided  to  the  Chief 
Executive Officer (CEO) and Chief Financial Officer (CFO) who together are considered the Group’s chief operating decision 
makers,  the  ‘CODM’.  An  operating  segment’s  operating  results  are  reviewed  regularly  by  the  CODM  to  make  decisions 
about resources to be allocated to the segment and assess its performance, and for which discrete financial information is 
available.

Segment results that are reported to the CODM include items directly attributable to a segment as well as those that can be 
allocated on a reasonable basis. Segment capital expenditure is the total cost incurred during the period to acquire property, 
plant and equipment and right-of-use assets.

Debt issuance costs

Debt issuance costs relating to the Group’s long-term debt are recorded as a direct reduction of long-term debt; these costs 
are deferred and amortised to interest expense using the effective interest method, over the respective terms of the related 
debt.  Debt  issuance  costs  relating  to  the  Group’s  revolving  credit  facilities  are  recorded  as  an  asset;  these  costs  are 
deferred  and  amortised  to  interest  expense  using  the  straight-line  method.  Early  repayment  of  debt  facilities  can  result  in 
modification of the debt and the acceleration of the amortisation of debt issuance costs.

2.  Segmental information

The Company has the expertise and capability to conduct clinical trials in most major therapeutic areas on a global basis 
and has the operational flexibility to provide development services on a stand-alone basis or as part of an integrated "full-
service" solution. The Company has expanded through internal growth, together with a number of strategic acquisitions to 
enhance its expertise and capabilities in certain areas of the clinical development process.

The Company determines and presents operating segments based on the information that is internally provided to the chief 
operating decision maker, together the ('CODM') in accordance with IFRS 8 Operating Segments. The Company determined 
that the CODM was comprised of the Chief Executive Officer and the Chief Financial Officer.

The Company operates as one reporting segment, which is the provision of outsourced development services on a global 
basis to the pharmaceutical, biotechnology and medical devices industries. 

The Group’s listing for its shares is the NASDAQ market in the United States. Consequently, information reviewed by the 
chief operating decision makers is prepared in accordance with US generally accepted accounting principles (“US GAAP”) 
however, the information presented below is prepared in accordance with IFRS reporting standards. Reconciliations of the 
Group’s profit for the financial year and shareholders’ equity from US GAAP to IFRS are set out on pages 149 to 153 of this 
report.  

Revenues  are  allocated  to  individual  entities  based  on  where  the  work  is  performed  in  accordance  with  the  Company's 
global  transfer  pricing  model.  Revenues  and  income  from  operations  in  Ireland  are  a  function  of  our  global  contracting 
model and the Group’s transfer pricing model.

ICON  Ireland  acts  as  the  Group  entrepreneur  under  the  Company’s  global  transfer  pricing  model  given  its  role  in  the 
development and management of the Group, its ownership of key intellectual property and customer relationships, its key 
role in the mitigation of risks faced by the Group and its responsibility for maintaining the Company’s global network. ICON 
Ireland enters into the majority of the Company’s customer contracts.

ICON Ireland remunerates other operating entities in the ICON Group on the basis of a guaranteed cost plus mark-up for 
the  services  they  perform  in  each  of  their  local  territories.  The  cost  plus  mark-up  for  each  ICON  entity  is  established  to 

56

Notes to Consolidated Financial Statements (continued)
for the year ended 31 December 2022

2.  Segmental information (continued)

ensure that each of ICON Ireland and the ICON entities that are involved in the conduct of services for customers, earn an 
appropriate arms-length return having regard to the assets owned, risks borne, and functions performed by each entity from 
these intercompany transactions. The cost plus mark-up policy is reviewed annually to ensure that it is market appropriate. 
The  integration  of  entities  acquired  through  the  Merger  into  this  global  network  and  global  transfer  pricing  model  remains 
ongoing.

The  geographic  split  of  revenue  disclosed  for  each  region  outside  Ireland  is  the  cost  plus  revenue  attributable  to  these 
entities. The residual revenues of the Group, once each ICON entity has been paid its respective intercompany service fee, 
generally fall to be retained by ICON Ireland. As such, revenues and income from operations in Ireland are a function of this 
global transfer pricing model and comprise revenues of the Group after deducting the cost plus revenues attributable to the 
activities performed outside Ireland.

There have been no changes to the basis of segmentation or the measurement basis for the segment results since the prior 
year.

The  total  tax  expense  of  $65.5  million  and  $40.2  million  for  the  years  ended  31  December  2022  and  31  December  2021 
respectively,  reflects  tax  at  standard  rates  on  taxable  profits  in  the  jurisdictions  in  which  the  Group  operates,  foreign 
withholding tax and the availability of tax losses.

The deferred tax credit of $119.7 million for the year ended 31 December 2022 and the deferred tax credit of $70.8 million 
for  the  year  ended  31  December  2021,  relates  to  deferred  tax  arising  in  respect  of  net  operating  losses  and  temporary 
differences in property, plant and equipment, the timing of certain goodwill amortisation on US acquisitions and the timing of 
tax deductions available relating to the Group’s share-based compensation schemes.

Unrecognised deferred tax assets

Deferred tax assets relating to the following net operating losses have not been recognised to the extent that it is considered 
unlikely that a benefit will be received in the future.  

At 31 December 2022, non-US subsidiaries had operating loss carry-forwards for income tax purposes that may be carried 
forward  indefinitely,  available  to  offset  against  future  taxable  income,  if  any,  of  approximately  $37.9  million  (31  December 
2021: $42.3 million). At 31 December 2022, non–US subsidiaries also had additional operating loss carry forwards of $14.8 
million which are due to expire between 2023 and 2029 and operating loss carry forwards of $18.2 million which are due to 
expire between 2030 and 2039.

In  total,  the  Company  has  unrecognised  deferred  tax  assets  of  $43.4  million  at  31  December  2022  and  $45.5  million  at 
31  December  2021.  The  Company  has  not  recognised  these  remaining  deferred  tax  assets  because  it  believes  that  it  is 
more likely than not that the losses and other deferred tax assets will not be utilised given their history of operating losses.

Unrecognised deferred tax liabilities

The  Company  has  recognised  a  deferred  tax  liability  of  $1.6  million  (2021:  $0.8  million)  for  investments  in  foreign 
subsidiaries where the Company does not consider the earnings to be indefinitely reinvested. For the deferred tax liability 
not recognised in respect of temporary differences related to investments in foreign subsidiaries which are considered to be 
indefinitely  reinvested,  it  is  not  practicable  to  calculate  the  exact  unrecognised  deferred  tax  liability,  however,  it  is  not 
expected to be material as Ireland allows a tax credit in respect of distributions from foreign subsidiaries at the statutory tax 
rate  in  the  jurisdiction  of  the  subsidiary  so  that  no  material  tax  liability  would  be  expected  to  arise  in  Ireland  in  the  event 
these earnings were ever remitted. In addition, withholding taxes applicable to remittances from foreign subsidiaries would 
not be expected to be material given Ireland’s tax treaty network and the EU parent subsidiary directive.

Transaction and integration related
In  the  years  ended  31  December  2022  and  31  December  2021  the  Company  incurred  $39.7  million  and  $124.4  million, 
respectively, of merger-related expenses which were accounted for separately from the business combination and expensed 
as incurred within the “Other operating expenses” line item of the Consolidated Statement of Profit and Loss. These costs

bonuses and ongoing integration activities. 

Accelerated stock compensation charge

Committee  seeks  to  foster  a  performance-oriented  environment  by  ensuring  that  a  significant  portion  of  each  executive’s 
cash and equity compensation is based on the achievement of performance targets that are important to the Company, its 
shareholders and other stakeholders.

The  Company’s  executive  compensation  programme  has  three  main  elements:  base  salary,  a  bonus  plan  and  equity 
incentives  in  the  form  of  share  related  awards  granted  under  the  Company’s  equity  incentive  plans. All  elements  of  key 
executives’ compensation are determined by the Compensation and Organisation Committee based on the achievement of 
the Group’s and individual performance objectives.

Non-Executive Directors’ remuneration

Non-Executive Directors are remunerated by way of Directors’ fees and are also eligible for participation in the share equity 
incentive schemes. During 2022, each Non-Executive Director (excluding the Board Chair) was paid an annual retainer of 
$90,000 and additional fees for Board Committee service.

Mr. Ciaran Murray’s Executive Chair term expired on 12 May 2018 and he transitioned to the role of Non-Executive Chair. 
The  current  arrangement  with  the  Chair  provides  for  payment  of  €330,000  (translated  at  average  rate  for  the  year: 
$346,891) annually.

Mr. Rónán Murphy was appointed as Lead Independent Director with effect from 1 January 2019 and receives an additional 
fee of $25,000 for this role.

Non-Executive Directors are not eligible for performance related cash bonuses and no pension contributions are made on 
their behalf. The Compensation and Organisation Committee sets non-Executive remuneration. 

Executive Directors’ and Key Executive Officers’ remuneration

Total cash  compensation is divided into a base salary  portion and a bonus incentive portion. The Committee targets total 
cash compensation with regard to healthcare/ biopharmaceutical companies of similar market capitalisation and peer CRO 
companies, adjusted upward or downward based on individual performance and experience and level of responsibility. The 
Compensation  and  Organisation  Committee  believes  that  the  higher  the  executive’s  level  of  responsibility  within  the 
Company, the greater the percentage of the executive’s compensation that should be tied to the Company’s performance. 
Target bonus incentive for executive officers range between 60% and 125% with actual pay outs for 2022 ranging from 48% 
to 100%, of salary, based on Group and individual performance.  

A total bonus of $1.5 million was awarded to the following individuals; Dr. Steve Cutler, Chief Executive Officer ($1.2  million) 
and  Mr.  Brendan  Brennan,  Chief  Financial  Officer  ($0.3  million)  to  reflect  their  contribution  to  the  performance  of  the 
Company  during  2022.  These  amounts  were  approved  by  the  Compensation  and  Organisation  Committee  and  bonuses 
were paid during the year ended 31 December 2023. 

The  Company’s  executives  are  eligible  to  receive  equity  incentives,  including  stock  options,  restricted  share  units  and 
performance share units, granted under the Company’s equity incentive plans. If executives receive equity incentive grants, 
they  are  normally  approved  annually  at  the  first  scheduled  meeting  of  the  Committee  in  the  fiscal  year. The  grant  date  is 
determined by the Committee, and grants are awarded at the closing price on the day of grant. Newly hired executives may 
receive  sign-on  grants.  In  addition,  the  Committee  may,  in  its  discretion,  issue  additional  equity  incentive  awards  to 
executives  if  the  Committee  determines  such  awards  are  necessary  to  ensure  appropriate  incentives  are  in  place.  The 
equity awards granted to each participant is determined primarily by the Committee at the start of each year based on peer 
groups and advice from independent compensation consultants. 

All  executive  officers  are  eligible  to  participate  in  pension  plans.  The  Company’s  contributions  are  generally  a  fixed 
percentage of their annual compensation, supplementing contributions by the executive. The Company has the discretion to 
make  additional  contributions  if  deemed  appropriate  by  the  Committee.  Contributions  to  this  plan  are  recorded  as  an 
expense in the Consolidated Statement of Profit and Loss.

Retirement benefit obligations 

The Group operates a number of defined contribution schemes and defined benefit pension schemes. The Group accounts 
for pensions in accordance with IAS 19R Employee Benefits (“IAS 19R”).

(i)

Defined Contribution Schemes

Certain  employees  of  the  Group  are  eligible  to  participate  in  a  defined  contribution  or  profit  sharing  plans  (the  "Plans"). 
Participants  in  the  Plans  may  elect  to  defer  a  portion  of  their  pre-tax  earnings  into  a  pension  plan,  which  is  run  by  an 
independent  party.  The  Group  matches  each  participant's  contributions  up  to  certain  levels  of  the  participant's  annual 
compensation. Contributions to the plan are recorded as a remuneration expense in the Consolidated Statement of Profit 
and Loss. Contributions for the year ended 31 December 2022 and year ended 31 December 2021 were $46.3 million and 
$37.1 million respectively.

Notes to Consolidated Financial Statements (continued)
for the year ended 31 December 2022
10.  Retirement benefit obligations (continued)

The  Group's  United  States  operations  maintain  retirement  plans  (the  "U.S.  Plans")  that  qualify  as  deferred  salary 
arrangements  under  Section  401(k)  of  the  Internal  Revenue  Code.  Participants  in  the  U.S.  Plans  may  elect  to  defer  a 
portion  of  their  earnings,  up  to  the  Internal  Revenue  Service  annual  contribution  limit.  The  Group  matches  participant's 
contributions at varying amounts, subject to a maximum of 4.5% of the participant's annual compensation. Contributions to 
the  U.S.  Plans  are  recorded,  in  the  year  contributed,  as  an  expense  in  the  Consolidated  Statement  of  Profit  and  Loss. 
Contributions  for  the  year  ended  31  December  2022  and  year  ended  31  December  2021  were  $30.2  million  and  $23.7 
million respectively.

Defined Benefit Plans

ICON Development Solutions Limited Pension Plan

One of the Group’s subsidiaries, ICON Development Solutions Limited, which was acquired by the Group in 2003, operates 
a defined benefit pension plan in the United Kingdom for certain employees, which is now closed to new members. 

The plan is managed externally and the related pension costs and liabilities are assessed in accordance with the advice of a 
professionally  qualified  actuary.  Plan  assets  at  31  December  2022  and  31  December  2021  consist  of  units  held  in 
independently administered funds.  

Financial assumptions

The following assumptions were used in determining the fair value of the plan assets and the present value of the projected 
benefit obligation at 31 December 2022:

Discount rate

Inflation rate

Future pension increases

Future salary increases

31 December
2022

31 December
2021

 4.88 %

 3.06 %

 3.18 %

 3.56 %

 1.75 %

 3.18 %

 2.90 %

 3.68 %

A single discount rate is used which, when used to discount the projected benefit cashflows underlying a pension scheme 
with a 26 year duration, gives the same result as a full AA corporate bond yield curve. 

The following assumptions were used at the commencement of the year in determining the net periodic pension cost for the 
year ended 31 December 2022:

Discount rate

Future salary increases

31 December
2022

31 December
2021

 1.75 %

Mortality assumptions

Assumptions regarding mortality experience are set based on actuarial advice in accordance with published statistics and 
experience. The mortality assumptions adopted at 31 December 2022 are 108% of the standard tables S3PMA/S3PFA_M, 
Year of Birth, no age rating for males and females, projected using CMI_2020  converging to 1.25% p.a.. These imply the 
following life expectancies, for persons retiring at age 62:

Male retiring in 2022

Female retiring in 2022

Male retiring in 2042

The plan’s assets do not include any of the Group’s own financial instruments, nor any property occupied by, or other assets 
used by the Group.  

At 31 December 2022 the long-term expected rate of return on cash is determined by reference to traditional corporate bond 
rates  at  the  latest  reporting  date.  The  long-term  expected  returns  on  traditional  corporate  and  government  bonds  are 
determined by reference to corporate bond yields and gilt yields respectively at the reporting date. The long-term expected 
returns on equities is based on the rate of return on government bonds with an allowance for out-performance. The long-
term  expected  return  on  high  yield  bonds,  secured  loans  and  multi  asset  credit  is  based  on  the  return  on  traditional 
corporate bonds with an allowance for out-performance. 

The underlying asset split of the funds at 31 December 2022 and 31 December 2021 was as follows:

Government Bonds

Diversified Bonds

Equities

Corporate Bonds (including 50% high yield bonds)

Secured Loans and Multi Asset Credit

The assets of the scheme are held on an investment platform with Mercer Limited which invests in a number of investment 
funds  with  MGI  and  Mercer  Sterling.  The  overall  investment  strategy  is  that  approximately  88%  of  investments  are  in 
government  bonds  and  index  linked  gilts  and  12%  in  diversified  bonds.  There  is  no  self-investment  in  employer  related 
assets.

Sensitivity assumptions

The sensitivity of the defined benefit obligation to changes in the weighted principal assumptions is:

Change in Assumption

Change in Liabilities

Discount Rate

Rate of Inflation

Rate of Salary Growth

Rate of Mortality

Decrease of 0.25% p.a.

Increase of 0.25% p.a.

Increase of 0.25% p.a.

Increase in life expectancy of 1 year

Increase by 4.8%

Increase by 0.8%

Increase by 0.1%

Increase by 2.7%

The sensitivities shown above are approximate. Each sensitivity considers one change in isolation. The inflation sensitivity 
includes the impact of changes to the assumptions for revaluation, pension increases and salary growth. 

The  plan  typically  exposes  the  Company  to  actuarial  risks  such  as  investment  risk,  interest  rate  risk,  salary  growth  risk, 
mortality risk and longevity risk. A decrease in bond yields, a rise in inflation or an increase in life expectancy would result in 
an  increase  to  plan  liabilities.  This  would  detrimentally  impact  the  Statement  of  Financial  Position  and  may  give  rise  to 
increased charges in future Statements of Profit and Loss. This effect would be partially offset by an increase in the value of 
the plan’s bond holdings, and in qualifying death in service insurance policies that cover mortality risk. Additionally, caps on 
inflationary increases are in place to protect the plan against extreme inflation.

Cash flows and Maturity Profiles

The Group expects to contribute approximately $0.1 million of normal contribution to the defined benefit pension scheme for 
the  year  ended  31  December  2023.  The  average  duration  of  the  defined  benefit  obligation  at  the  period  ending 
31 December 2022 is 19 years.

Aptiv Solutions Pension Plan

On 7 May 2014, the Company acquired 100% of the common stock of Aptiv Solutions (“Aptiv”). The acquisition of Aptiv was 
accounted for as a business combination in accordance with IFRS 3 Business Combinations. The Company has a defined 
benefit  plan  covering  its  employees  in  Switzerland  as  mandated  by  the  Swiss  government.  Benefits  are  based  on  the 
employee’s years of service and compensation. The plan is managed externally and the related pension costs and liabilities 
are  assessed  in  accordance  with  the  advice  of  a  professionally  qualified  actuary.  Plan  assets  at 31  December  2022  and

Share Options

On  21  July  2008  the  Company  adopted  the  Employee  Share  Option  Plan  2008  (the  “2008  Employee  Plan”)  pursuant  to 
which  the  Compensation  and  Organisation  Committee  of  the  Company’s  Board  of  Directors  may  grant  options  to  any 
employee,  or  any  director  holding  a  salaried  office  or  employment  with  the  Company  or  a  Subsidiary  for  the  purchase  of 
ordinary  shares.  On  the  same  date,  the  Company  also  adopted  the  Consultants  Share  Option  Plan  2008  (the  “2008 
Consultants Plan”), pursuant to which the Compensation and Organisation Committee of the Company’s Board of Directors 
may grant options to any consultant, adviser or non-Executive Director retained by the Company or any Subsidiary for the 
purchase of ordinary shares. 

On 14 February 2017 both the 2008 Employee Plan and the 2008 Consultants Plan (together the “2008 Option Plans”) were 
amended and restated in order to increase the number of options that can be issued under the 2008 Consultants Plan from 
0.4 million to 1.0 million and to extend the date for options to be granted under the 2008 Option Plans.

An aggregate of 6.0 million ordinary shares have been reserved under the 2008 Employee Plan, as reduced by any shares 
issued  or  to  be  issued  pursuant  to  options  granted  under  the  2008  Consultants  Plan,  under  which  a  limit  of  1.0  million 
shares applies. Further, the maximum number of ordinary shares with respect to which options may be granted under the 
2008  Employee  Option  Plan,  during  any  calendar  year  to  any  employee  shall  be  0.4  million  ordinary  shares. There  is  no 
individual limit under the 2008 Consultants Plan. No options may be granted under the 2008 Option Plans after 14 February 
2027.

Each option granted under the 2008 Employees Plan or the 2008 Consultants Plan (together the “2008 Option plans”) will 
be evidenced by a Stock Option Agreement between the optionee and the Company. The exercise price will be specified in 
each  Stock  Option Agreement,  however,  option  prices  will  not  be  less  than  100%  of  the  fair  market  value  of  an  ordinary 
share on the date the option is granted.

PRA Equity Incentive Plans

The following represents the PRA equity incentive plans, which still have equity outstanding but have been terminated as of 
1 July 2021, as to grants of future awards.

Pursuant to the Merger Agreement, effective on 1 July 2021, each outstanding stock option and restricted stock unit under 
the PRA Plans was assumed by the Company and converted into a stock option or Restricted Share Unit exercisable for or 
payable in Ordinary Shares based on the ratio of the average trading price per Ordinary Share for the ten days prior to 1 
July 2021, and the corresponding value of the Merger consideration for each PRA Share. Accordingly, the plans as detailed 
below were assumed by the Company.

PRA Health Sciences, Inc. 2020 Stock Incentive Plan was amended and restated and assumed by ICON effective as of 1 
July 2021. The 2020 Stock Incentive Plan (“the 2020 Plan”), was approved by the PRA stockholders at their annual meeting 
on 18 May 2020. The 2020 Plan allowed for the issuance of stock options, stock appreciation rights, restricted shares and 
restricted stock units, other stock-based awards, and performance compensation awards as permitted by applicable laws. 
The 2020 Plan authorised the issuance of 2,500,000 shares of common stock plus all shares that remained available under 
the prior plan on 18 May 2020.

The  PRA  Health  Sciences,  Inc.  2018  Stock  Incentive  Plan  was  amended  and  restated  and  assumed  by  the  Company 
effective as of 1 July 2021. The 2018 Stock Incentive Plan (the “2018 Plan”), was approved by the PRA stockholders at their 
annual  meeting  on  31  May  2018.  The  2018  Plan  allowed  for  the  issuance  of  stock  options,  stock  appreciation  rights, 
restricted shares and restricted stock units, other stock-based awards, and performance compensation awards as permitted 
by  applicable  laws.  The  2018  Plan  authorised  the  issuance  of  2,000,000  shares  of  common  stock  plus  all  shares  that 
remained available under the 2014 Plan on 31 May 2018 (which included shares carried over from the 2013 Plan).

The  PRA  Health  Sciences,  Inc.  2014  Omnibus  Incentive  Plan  was  amended  and  restated  and  assumed  by  the  Company 
effective  as  of  1  July  2021  (the  “2014  Plan”).  On  23  November  2014,  the  PRA  Health  Sciences,  Inc.  Board  of  Directors 
approved the formation of the 2014 Plan for Key PRA Employees. The 2014 Plan allowed for the issuance of stock options, 
stock  appreciation  rights,  restricted  shares  and  restricted  stock  units,  other  stock-based  awards,  and  performance 
compensation awards as permitted by applicable laws.

The 2013 Stock Incentive Plan for Key Employees of PRA Health Sciences and its Subsidiaries was amended and restated 
and assumed by ICON effective as of 1 July 2021 (the “2013 Plan”). On 23 September 2013, the PRA Health Sciences, Inc. 
Board  of  Directors  approved  the  formation  of  the  2013  Plan  for  Key  Employees  of  Pinnacle  Holdco  Parent,  Inc.  and  its 
subsidiaries.  The  2013  Plan  allowed  for  the  issuance  of  stock  options  and  other  stock-based  awards  as  permitted  by 
applicable  laws.  The  number  of  shares  available  for  grant  under  the  2013  Plan  was  12.5%  of  the  outstanding  shares  at 
closing on a fully diluted basis. The 2013 Plan authorised the issuance of 2,052,909 shares of common stock.

Fair value of share options – Assumptions

The fair values of options granted during the year ended 31 December 2022 and the year ended 31 December 2021 were 
calculated using a binomial option-pricing-model, using the following assumptions:

Weighted average exercise price
Expected volatility (1)
Expected dividend yield
Risk-free rate (2)
Rate of forced early exercise

commensurate with the expected term of the options granted.
(2) Risk-free rate is dependent on the grant date and term of the award.

Restricted Share Units and Performance Share Units

On 23 April 2013 the Company adopted the 2013 Employees Restricted Share Unit and Performance Share Unit Plan (the 
“2013 RSU Plan”) pursuant to which the Compensation and Organisation Committee of the Company’s Board of Directors 
may  select  any  employee,  or  any  Director  holding  a  salaried  office  or  employment  with  the  Company,  or  a  Subsidiary  to 
receive an award under the plan. On 11 May 2015 the 2013 RSU Plan was amended and restated in order to increase the 
number  of  shares  that  can  be  issued  under  the  RSU  Plan  by  2.5  million  shares. Accordingly,  an  aggregate  of  4.1  million 
ordinary shares have been reserved for issuance under the 2013 RSU Plan. The shares are awarded at zero cost and vest 
over a service period. Awards under the 2013 RSU Plan may be settled in cash or shares at the option of the Company. No 
awards may be granted under the 2013 RSU Plan after 11 May 2025.

On  30  April  2019  the  Company  approved  the  2019  Consultants  and  Directors  Restricted  Share  Unit  Plan  (the  “2019 
Consultants  RSU  Plan”),  which  was  effective  as  of  16  May  2019,  pursuant  to  which  the  Compensation  and  Organisation 
Committee of the Company’s Board of Directors may select any consultant, adviser or non-executive Director retained by 
the Company, or a Subsidiary to receive an award under the plan. 250,000 ordinary shares have been reserved for issuance 
under the 2019 Consultants RSU Plan. The awards are at par value and vest over a service period. Awards granted to non-
executive directors during 2020 and 2021 vest over twelve months. 

The Company has awarded RSUs and PSUs to certain key individuals of the Group. The fair value of RSUs is based on the 
share price at the date of grant, with the expense spread over the vesting period. The following table summarises RSU and 
PSU activity for the year ended 31 December 2022:

Depending on the actual amount of EPS from 2022 to 2024, up to an additional 76,210 PSUs may also be granted.

Notes to Consolidated Financial Statements (continued)
for the year ended 31 December 2022

13.  Intangible assets - goodwill and other (continued)

Impairment review of goodwill

Goodwill is subject to impairment testing on an annual basis, or more frequently if there are indicators of impairment. These 
assets are allocated to groups of cash generating units (CGUs). The recoverable amount of each of the CGUs is determined 
based  on  value-in-use  calculations.  Goodwill  acquired  through  business  combinations  has  been  allocated  to  the  Group’s 
three  CGUs. The  CGUs  identified  represent  the  lowest  level  within  the  Group  at  which  goodwill  is  monitored  and  are  not 
larger than the operating segment determined in accordance with IFRS 8 Operating Segments. 

The Group has identified three CGUs in accordance with the provisions of IAS 36 Impairment of Assets. 

A summary of the allocation of the carrying value of goodwill by CGU, is as follows:

Impairment testing methodology and results

Cash flow forecasts employed for the value-in-use calculations are for a five year period approved by management and a 
terminal value which is applied to the year five cash flows. The terminal value reflects the discounted value of the cash flows 
beyond year five which is based on the weighted average long-term growth rates for each CGU.

Management’s  estimates  of  future  cash  flows  are  based  upon  current  budgets  and  strategic  plans  and  are  reflective  of 
anticipated  growth  rates  within  the  CRO  industry,  expected  growth  in  the  Group’s  market  share  and  reflective  of  past 
experience.  Key  assumptions  applied  in  determining  expected  future  cash  flows  for  these  plans  include  management’s 
estimate of future profitability, replacement capital expenditure requirements, trade working capital investment needs and tax 
considerations.  The Group’s cash flow projections are adjusted each year for actual and expected changes in performance. 

The  following  assumptions  were  applied  in  determining  the  five  year  projected  cash  flows  of  the  three  CGUs  at 
31 December 2022:

Expected revenue growth rate

Expected growth rate for operating costs

Expected effective tax rate

Expected annual working capital growth rate

Expected capital expenditure growth rate

Notes to Consolidated Financial Statements (continued)
for the year ended 31 December 2022

13.  Intangible assets - goodwill and other (continued)

Expected  revenue  growth  and  the  expected  growth  in  operating  costs  are  determined  based  upon  the  expected  growth 
rates  used  in  preparing  the  Group’s  budgets  and  strategic  plans.  In  estimating  budget  revenue,  consideration  is  given  to 
current levels of backlog (i.e. the value of new business awards not yet recognised in revenue) and the estimated timeframe 
over which this is expected to be recognised within revenue, together with an estimate of revenue expected to be generated 
from new awards not currently within backlog. In estimating revenue from new awards consideration is given to current RFP 
(request for proposals) volumes, expected growth rates in both the CRO industry and the Group’s market share, and of past 
experience. In estimating budgeted operating costs, consideration is given to required staffing levels, project related costs, 
facility and information technology costs and other costs. Staff costs and project related costs generally increase in line with 
revenue and are therefore estimated based on revenue growth expectations, while facility and information costs and other 
costs are relatively fixed and are therefore projected based upon a lower growth rate. An expected long-term average tax 
rate of 15.5% has been applied in determining the projected after tax cash flows.

Expected annual working capital growth and expected capital expenditure growth are based upon the expected growth rates 
used in preparing the Group’s budgets and strategic plans. Long term growth rates were based on global macroeconomic 
data.

A  pre-tax  discount  rate  of  11.5%  (2021:  between  11.6%  and  12.1%)  has  been  applied  to  the  projected  cash  flows  of  the 
CGUs in determining its value-in-use. This rate is reflective of both the time value of money and risks specific to the CGUs. 
The discount rate is based upon the Group’s weighted average cost of capital which has been determined by applying the 
Group’s  long-term  optimal  capital  structure  to  its  costs  of  debt  and  cost  of  equity.  The  Group’s  cost  of  debt  has  been 
calculated by applying an appropriate margin over the risk-free interest rate. The Group’s cost of equity has been calculated 
using the capital asset pricing model and includes an appropriate equity risk premium over the available risk-free interest 
rate. The  Group’s  weighted  average  cost  of  capital  is  adjusted  to  reflected  additional  risk  premiums  associated  with  each 
CGU.

No  impairment  was  recognised  in  2022  or  2021  as  a  result  of  the  impairment  testing  which  identified  headroom  in  the 
recoverable amount of the related CGUs as compared to their carrying value.

Sensitivity Analysis

A sensitivity analysis to determine if reasonable changes in key assumptions could lead to an impairment was conducted at 
31 December 2022. The table below identifies the amounts by which each of the specified assumptions may either decline 
or  increase  to  arrive  at  a  zero  excess  of  the  present  value  of  future  cash  flows  over  the  carrying  value  of  goodwill  in  the 
CGU:

Management believes that the assumptions originally used in the value-in-use models are sufficiently prudent to ensure no 
reasonable change, in normal circumstances, in any of the above key assumptions would cause the carrying value of any 
CGU to exceed its recoverable amount.

(a)  

PRA Health Sciences, Inc.

On 1 July 2021 (the "Merger Date"), the Company completed the Acquisition of PRA by means of a merger whereby Indigo 
Merger  Sub,  Inc.,  a  Delaware  corporation  and  subsidiary  of  ICON,  merged  with  and  into  PRA  Health  Sciences,  Inc.,  the 
parent of the PRA Health Sciences Group ("the Acquisition" and "the Merger"). The combined Group has retained the name 
ICON and brought together approximately 38,000 (as at the Merger date) employees across the globe, creating one of the 
world’s  most  advanced  healthcare  intelligence  and  clinical  research  organisation.  The  Merger  was  accounted  for  as  a 
business combination using the acquisition method of accounting in accordance with IFRS 3 'Business Combinations'.

The combined Company leverages its enhanced operations to transform clinical trials and accelerate biopharma customers’ 
commercial  success  through  the  development  of  much  needed  medicines  and  medical  devices.  The  new  ICON  has  a 
renewed  focus  on  leveraging  data,  applying  technology  and  accessing  diverse  patient  populations  to  speed  up  drug 
development.

Upon completion of the Merger, pursuant to the terms of the Merger Agreement, PRA became a wholly owned subsidiary of 
the ICON Group. Under the terms of the Merger, PRA shareholders received per share $80 in cash and 0.4125 shares of 
ICON stock. The trading of PRA common stock on NASDAQ was suspended prior to market open on 1 July 2021. .

In  the  years  ended  31  December  2022  and  31  December  2021,  the  Company  incurred  $39.7  million  and  $124.4  million, 
respectively, of Merger-related expenses which were accounted for separately from the business combination and expensed 
as incurred within the Other Operating Expenses line item of the Consolidated Statement of Profit and Loss. These costs 
consist  primarily  of  investment  banker  fees,  advisory  fees,  legal  costs,  accounting  and  consulting  fees,  and  employee 
retention bonuses. Included in transaction and integration costs for the years ended 31 December 2022 and 31 December 
2021 are acquisition related costs (as defined by IFRS 3) of $0.8 million and $57.1 million, respectively. These costs include 
finders fees, advisory, legal, accounting, valuation, and other professional or consulting fees.

The  Company  also  incurred  approximately  $86.7  million  of  Merger-related  financing  fees  and  amortisation  of  previously 
deferred fees which are included in the “Interest expense” line item in the Consolidated Statement of Profit and Loss for the 
year ended 31 December 2021. During the year ended 31 December 2021, the Company deferred $76.2 million of financing 
costs incurred as a result of the Senior Secured Credit Facility and Senior Secured Notes. These costs are being amortised 
over the term of the related debt.

The Merger Date fair value of the consideration transferred consisted of the following:

Accounts receivables are amounts due from customers for services performed in the ordinary course of business. They are 
generally  due  for  settlement  within  30-90  days  and  therefore  are  all  classified  as  current.  Accounts  receivable  are 
recognised  initially  at  the  amount  of  consideration  that  is  unconditional.  Accounts  receivable  balances  do  not  contain 
significant financing components. The Group holds the accounts receivable with the objective to collect the contractual cash 
flows and therefore measures them subsequently at amortised cost.   

All receivables are due within twelve months of the year ended 31 December 2022. Due to the short-term nature of the 
current receivables, their carrying amount is considered to be the same as their fair value.

Timing may differ between the satisfaction of performance obligations and the invoicing and collection of amounts related to 
our contracts with customers. We record assets for amounts related to performance obligations that are satisfied but not yet 
billed and/or collected. These assets are recorded as unbilled revenue and therefore contract assets rather than accounts 
receivables  when  receipt  of  the  consideration  is  conditional  on  something  other  than  the  passage  of  time.  Liabilities  are 
recorded for amounts that are collected in advance of the satisfaction of performance obligations or billed in advance of the 
revenue being earned.

Unbilled services/revenue balances arise where invoicing or billing is based on the timing of agreed milestones related to 
service  contracts  for  clinical  research.  Contractual  billing  arrangements  in  respect  of  certain  reimbursable  expenses 
(principally investigators) require billing by the investigator to the Company prior to billing by the Company to the customer.    

The  Company  is  the  contract  principal  in  respect  of  both  direct  services  and  in  the  use  of  third  parties  (principally 
investigator services) that support a clinical trial. The progress towards completion for clinical service contracts is measured 
based on total project costs (including reimbursable costs). Reimbursable expenses are included within direct costs and are 
recorded  based  on  activity  undertaken  by  the  third-party.  Amounts  owed  to  investigators  and  others  in  respect  of 
reimbursable  expenses  was  $406.3  million  at  31  December  2022  and  $323.6  million  at  31  December  2021  (see  note  20 
Accrued and other liabilities).  

Unbilled  services  as  at  31  December  2022  increased  by  $334.5  million  as  compared  to  31  December  2021.  Unearned 
revenue  increased  by  $191.5  million  resulting  in  a  decrease  of  $143.0  million  in  the  net  balance  of  unbilled  services  and 
unearned  revenue  between  31  December  2021  and  31  December  2022.  These  fluctuations  are  primarily  due  to  the 
completion of the Merger on 1 July 2021 but are also partially due to timing of payments and invoicing related to the Group's 
clinical trial management contracts. Billings and payments are established by contractual provisions including predetermined 
payment  schedules  which  may  or  may  not  correspond  to  the  timing  of  the  transfer  of  control  of  the  Company's  services 
under the contract. Unbilled services arise from long-term contract when a cost-based input method of revenue recognition 
is applied and revenue recognised exceeds the amount billed to the customer. 

As  of  31  December  2022  approximately $13.7  billion  (2021:  $13.3  billion)  of  revenue  is  expected  to  be  recognised  in  the 
future in respect of unsatisfied performance obligations. The Company expects to recognise revenue on approximately 48% 
(2021:  48%)  of  the  unrealised  performance  obligation  over  the  next  12  months,  with  the  remainder  recognised  thereafter 
over the duration of the customer contracts.  

Impairment of financial assets

At 31 December 2022, the Group maintained an impairment provision of $20.6 million (2021: $7.1 million). The credit loss 
expense  recognised  on  the  Group's  receivables  and  unbilled  services  was  $17.8  million  and  $0.7  million  for  the  twelve 
months ended 31 December 2022 and 2021, respectively.

The Group's estimate of expected credit losses considers historical credit loss information that is adjusted, where necessary, 
for current conditions and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the 
estimation of expected credit losses. The Group's receivables and unbilled services are predominantly due from large and 
mid-tier  pharmaceutical  and  biotechnology  companies  that  share  similar  risk  characteristics.  The  Group  monitors  their 
portfolio of receivables and unbilled services for any deterioration in current or expected credit quality (for example expected 
delinquency level), and adjusts the allowance for credit losses as required. Receivables for which an impairment provision 
was recognised were written off against the provision when there was no expectation of recovering additional cash.

The Group considered that there was evidence of impairment if any of the following indicators were present: 

•
•
•

significant financial difficulties of the debtor
probability that the debtor will enter a financial restructuring process, and 
default or late payment

(b) Non-current financial assets - fair value through profit or loss

The  Company  entered  into  subscription  agreements  with  a  number  of  funds.  Capital  totalling  $20.6  million  had  been 
advanced  under  the  terms  of  the  subscription  agreements  at  31  December  2022  (2021:  $16.9  million).  The  Company 
determined  that  the  interests  in  the  funds  meet  the  definition  of  equity  securities  without  readily  determinable  fair  values. 
There  was  an  increase  in  fair  value  of  $6.3  million  (2021:  $3.2  million)  recognised  in  profit  during  the  year  bringing  the 
carrying value of the subscriptions to $32.6 million at 31 December 2022 (2021: $22.6 million). At 31 December 2022, the 
Company had committed to future investments of $23.3 million in respect of these funds.

(c) Equity method investments

The Company has invested $4.9 million to obtain a 49% interest in the voting share capital of Oncacare. The Company’s 
investment  in  Oncacare  is  accounted  for  under  the  equity  method  due  to  the  Company's  ability  to  exercise  significant 
influence  over  Oncacare  that  is  considered  to  be  greater  than  minor.  The  Company  records  its  pro  rata  share  of  the 
earnings/losses of this investment in 'Share of equity method investment' in the Consolidated Statement of Profit and Loss 
(see note 1 Basis of preparation and statement of accounting policies). 

Oncacare is incorporated in Ireland and operates throughout Europe and the United States.

The majority investor has the right to sell the 51% majority voting share capital exclusively to the Company in a two and half 
year period, commencing 1 January 2023 and ICON also has the right to acquire the 51% majority voting share capital from 
1 August 2025. The following table represents our equity method investment at 31 December 2022:

During the year ended 31 December 2021, the Company provided a loan of $10 million to Oncacare in order to fund the 
continued development of the business operations. The loan accrues annual interest at 1.6% and the loan is repayable on 
30 June, 2025.

For  the  year  ended 31  December  2022,  the  Company  has  recorded  a  loss  of $3.1  million  (31  December  2021:  loss  $2.2 
million) representing its pro rata share of the losses in Oncacare. During the year ended 31 December 2022, the carrying 
value of the Company's investment in Oncacare was reduced by $2.3 million of pro rata losses. The remaining $0.8 million 
in pro rata losses served to reduce the carrying value of the Company's loan receivable from Oncacare. The outstanding 
balance of the Company's loan receivable with Oncacare at 31 December, 2022 is $9.2 million. 

On April  20,  2023,  the  Company  completed  the  purchase  of  the  majority  investor’s  51%  majority  voting  share  capital  of 
Oncacare . As a result of this transaction, Oncacare became a wholly owned subsidiary of the ICON Group. See Note 31 for

The  Company's  primary  financing  arrangements  are  its  senior  secured  credit  facilities  (the  "Senior  Secured  Credit 
Facilities"), which consists of a senior secured term  loan and a revolving credit facility, and the senior secured notes  (the 
"Senior Secured Notes").

Senior Secured Credit Facilities

In  conjunction  with  the  completion  of  the  Merger  Agreement,  on  1  July  2021,  ICON  entered  into  a  credit  agreement 
providing  for  a  senior  secured  term  loan  facility  of  $5,515  million  and  a  senior  secured  revolving  loan  facility  in  an  initial 
aggregate principal amount of $300 million. The proceeds of the senior secured term loan facility were used to repay in full 
(i)  PRA’s  existing  credit  facilities  and  (ii)  the  Company's  private  placement  notes  outstanding  and  fund,  in  part,  the 
transaction. The senior secured term loan facility will mature in July 2028 and the revolving loan facility will mature in July 
2026. The  credit  agreement  governing  the  Senior  Secured  Credit  Facilities  provides  that  borrowings  denominated  in  U.S. 
Dollars will bear interest based on LIBOR or the base rate (as elected by the borrower), plus an applicable margin.  On the 
29th  of  November  2022,  the  Company  agreed  with  its  lenders  to  the  early  adoption  of Term  SOFR  as  the  reference  rate 
within  the  Credit  Agreement  ahead  of  the  June  2023  USD  LIBOR  cessation  date.  LIBOR  is  no  longer  an  applicable 
reference rate available to the Company under the terms of the Credit Agreement.

Borrowings under the senior secured term loan facility amortise in equal quarterly installments in an amount equal to 1.00% 
per annum of the principal amount, with the remaining balance due at final maturity. The interest rate margin applicable to 
borrowings under the senior secured term loan facility is USD Term SOFR and a Term SOFR Adjustment depending on the 
interest  period  chosen  plus  an  applicable  margin  of  2.25%.  The  senior  secured  term  loan  facility  is  subject  to  a  floor  of 
0.50%.

The interest rate margin applicable to borrowings under the revolving loan facility will be, at the option of the borrower, either 
(i) the applicable base rate plus an applicable margin of 1.00%, 0.60% or 0.25% based on ICON’s current corporate family 
rating  assigned  by  S&P  of  BB-  (or  lower),  BB  or  BB+  (or  higher),  respectively,  or  (ii)  Term  SOFR  plus  a  Term  SOFR 
Adjustment  on  the  interest  period  chosen  plus  an  applicable  margin  of  2.00%,  1.60%  or  1.25%  based  on  ICON’s  current 
corporate family rating assigned by S&P of BB- (or lower), BB or BB+ (or higher), respectively. In addition, lenders under the 
revolving loan facility are entitled to commitment fees as a percentage of the applicable margin at the time of drawing and 
utilization fees dependent on the proportion of the facility drawn. At December 31, 2022, $300.0 million remained undrawn 
under the senior secured revolving loan facility.

The Borrowers’ (as defined in the credit agreement) obligations under the Senior Secured Credit Facilities are guaranteed 
by  ICON  and  the  subsidiary  guarantors. The  Senior  Secured  Credit  Facilities  are  secured  by  a  lien  on  substantially  all  of 
ICON’s,  the  Borrowers’  and  each  of  the  subsidiary  guarantor’s  assets  (subject  to  certain  exceptions),  and  the  Senior 
Secured Credit Facilities will have a first-priority lien on such assets, which will rank pari passu with the lien securing the 
Senior Secured Notes (see below), subject to other permitted liens.  The Company is permitted to make prepayments on the 
senior  secured  term  loan  without  penalty.  The  Company's  long-term  debt  arrangements  contain  customary  restrictive 
covenants and, as of 31 December 2022, we were in compliance with our restrictive covenants in all material respects.

23.  Bank credit lines and loan facilities (continued)

On  30  December  2022,  the  Company  repaid $200.0  million  of  the  senior  secured  term  loan  facility  and  made  a  quarterly 
interest  payment  of  $66.1  million.  This  repayment  resulted  in  an  additional  charge  associated  with  previously  capitalised 
fees of $1.8 million. 

On 30 September 2022, the Company repaid $200.0 million of the senior secured term loan facility and made a quarterly 
interest  payment  of  $53.6  million.  This  repayment  resulted  in  an  additional  charge  associated  with  previously  capitalised 
fees of $1.9 million. 

On 30 June 2022, the Company repaid $100.0 million of the senior secured term loan facility and made a quarterly interest 
payment  of  $39.4  million.  This  repayment  resulted  in  an  additional  charge  associated  with  previously  capitalised  fees  of 
$0.9 million. 

On 31 March 2022, the Company repaid $300.0 million of the senior secured term loan facility and made a quarterly interest 
payment  of  $35.1  million.  This  repayment  resulted  in  an  additional  charge  associated  with  previously  capitalised  fees  of 
$3.2 million. 

On  29  December  2021,  the  Company  repaid $500.0  million  of  the  senior  secured  term  loan  facility  and  made  a  quarterly 
interest  payment  of  $40.8  million.  This  repayment  resulted  in  an  additional  charge  associated  with  previously  capitalised 
fees of $5.6 million. 

On  27  September  2021,  the  Company  repaid  $13.8  million  of  the  senior  secured  term  loan  facility  and  made  a  quarterly 
interest payment of $40.4 million.

Senior Secured Notes

In  addition  to  the  Senior  Secured  Credit  Facilities,  on  1  July  2021,  a  subsidiary  of  the  Company  issued  $500  million  in 
aggregate  principal  amount  of  2.875%  senior  secured  notes  due  2026  in  a  private  offering  (the  “Offering”).  The  Senior 
Secured  Notes  will  mature  on  15  July  2026.  The  proceeds  from  the  Offering  and  borrowings  made  under  the  Senior 
Secured Credit Facilities, together with cash on hand, were used to (i) fund the cash consideration payable by ICON for the 
Merger,  (ii)  repay  existing  indebtedness  of  ICON  and  PRA  and  (iii)  pay  fees  and  expenses  related  to  the  Merger,  the 
Offering and the Senior Secured Credit Facilities. The Senior Secured Notes are guaranteed on a senior secured basis by 
ICON and its direct and indirect subsidiaries that guarantee the Senior Secured Credit Facilities.

Fair Value of Debt

The  estimated  fair  value  of  the  Company’s  debt  was  $4,650.3  million  and  $5,507.2  million  at  31  December  2022  and 
31  December  2021,  respectively.  The  fair  values  of  the  Senior  Secured  Credit  Facilities  and  Senior  Secured  Notes  were 
determined based on Level 2 inputs, which are based on rates at which the debt is traded among financial institutions.

Derivatives

The Company has entered into interest rate cap and swap agreements for purposes of managing its exposure to interest 
rate  fluctuations.  These  financial  derivative  agreements  are  designated  as  Cash  Flow  Hedges.    See  note  26  -  Financial 
Instruments for related information and disclosures.

(b) 

Share repurchase programme

A  resolution  was  passed  at  the  Company’s  Annual  General  Meeting  (“AGM”)  on  22  July  2016,  which  authorised  the 
Directors to purchase (buyback) up to 10% of the outstanding shares in the Company. This authorisation was renewed at 
the Company's AGM on each of 25 July 2017, 24 July 2018, 23 July 2019, 21 July 2020, 20 July 2021 and 26 July 2022. On 
3  October  2016,  the  Company  commenced  a  share  buyback  programme  of  up  to  $400  million.  The  share  buyback 
programme was completed during the year ended 31 December 2018 with a total of 4,026,576 ordinary shares redeemed 
for  a  total  consideration  of  $372.1  million.  On  8  January  2019,  the  Company  commenced  a  further  share  buyback 
programme  of  up  to  1.0  million  ordinary  shares  which  was  completed  during  the  year  ended  31  December  2019.  These 
shares  were  redeemed  by  the  Company  for  a  total  consideration  of  $141.6  million.  On  22  October  2019,  the  Company 
commenced  a  further  share  buyback  programme. At  31  December  2019,  35,100  ordinary  shares  were  redeemed  by  the 
Company  for  a  total  consideration  of  $5.3  million.  During  the  year  ended  31  December  2020,  1,235,218  ordinary  shares 
were redeemed by the Company under this buyback programme for a total consideration of $175.0 million. On 18 February

Notes to Consolidated Financial Statements (continued)

24.  Share capital (continued) 

2022, the Company commenced a further share buyback programme. During the year ended 31 December 2022, 420,530 
ordinary shares were redeemed by the Company for total consideration of $100.0 million.

All ordinary shares that were redeemed under the buyback programme were cancelled in accordance with the Constitution 
of the Company and the nominal value of these shares transferred to other undenominated capital as required under Irish 
Company law.

Under the repurchase programme, a broker purchased the Company’s shares from time to time on the open market or in 
privately negotiated transactions in accordance with agreed terms and limitations. The programme was designed to allow 
share  repurchases  during  periods  when  the  Company  would  ordinarily  not  be  permitted  to  do  so  because  it  may  be  in 
possession  of  material  non-public  or  price-sensitive  information,  applicable  insider  trading  laws  or  self-imposed  trading 
blackout  periods.  The  Company’s  instructions  to  the  broker  were  irrevocable  and  the  trading  decisions  in  respect  of  the 
repurchase  programme  were  made  independently  of  and  uninfluenced  by  the  Company.  The  Company  confirms  that  on 
entering  the  share  repurchase  plans  it  had  no  material  non-public,  price-sensitive  or  inside  information  regarding  the 
Company  or  its  securities.  Furthermore,  the  Company  will  not  enter  into  additional  plans  whilst  in  possession  of  such 
information.  The  timing  and  actual  number  of  shares  acquired  by  way  of  the  redemption  will  be  dependent  on  market 
conditions, legal and regulatory requirements and the other terms and limitations contained in the programme. In addition, 
acquisitions  under  the  programme  may  be  suspended  or  discontinued  in  certain  circumstances  in  accordance  with  the 
agreed terms. Therefore, there can be no assurance as to the timing or number of shares that may be acquired under the 
programme.

Share-based payment reserve
The share-based payment reserve is used to account for share-based payments. The fair value of share-based payments is 
expensed  to  the  Consolidated  Statement  of  Profit  and  Loss  over  the  period  the  related  services  are  received,  with  a 
corresponding  increase  in  equity. At  31  December  2022  the  Group  has  recognised  a  cumulative  charge  for  share-based 
payments of $717.6 million net of deferred tax (2021: $661.7 million).  The Group has also recognised a cumulative credit of 
$57.8  million  (2021:  $81.8  million)  in  reserves  for  the  current  and  deferred  tax  effects  of  the  tax  benefits  relating  to  the 
exercise of employee share options in excess of related cumulative compensation expense. The Group has reclassified a 
cumulative  credit  of  $394.2  million  (2021:  $322.5  million)  to  retained  earnings  in  respect  of  exercised  and  expired  share-
based awards.

Other undenominated capital
Other  undenominated  capital  comprises  the  nominal  value  of  shares  repurchased  and  cancelled  by  the  Company  and 
transferred from share capital to other undenominated capital as required under Irish Company Law. During the year ended 
31 December 2022, 420,530 ordinary shares were repurchased and cancelled by the Group (31 December 2021: Nil).

Other reserves
The  Group  has  recognised  a  non-distributable  reserve  of  $5.3  million  in  accordance  with  agreements  made  between  the 
Group and Enterprise Ireland, an Irish government agency. The requirement for these non-distributable reserves will expire 
between the period 2022 and 2025. In 2005 the Group also recognised a capital contribution of $6.1 million being the fair 
value of outstanding ordinary shares transferred to Mr Peter Gray, formerly Vice Chair of the Board of Directors and formerly 
Chief Executive Officer, by founding Directors, Dr. John Climax and Dr. Ronan Lambe.

During  the  year  ended  31  December  2022,  the  Group  entered  into  two  interest  rate  cap  agreements  and  an  interest  rate 
swap  agreement  to  limit  its  exposure  to  changes  in  the  variable  interest  rate  on  its  Senior  Secured  Credit  Facilities.  The 
interest rate caps and swap are accounted for as cash flow hedges and were considered effective hedges on application of 
the  provisions  of  IFRS  9.  The  effective  portion  of  the  hedges  for  the  year  ended  31  December  2022  is  recorded  as  a 
movement of $3.7 million within Other Reserves.

Currency reserve
The currency reserve comprises all foreign exchange differences arising from the translation of the financial statements of 
foreign currency denominated operations of the Group since 1 June 2004, the date of transition to IFRS. As at 31 December 
2022, this amounted to a cumulative loss of $175.1 million (2021: loss of $86.6 million). 

Share premium
Share premium is the difference between the nominal value of shares and the value of consideration for shares issued. 

Merger reserve
On 1 July 2021, the Company completed the Acquisition of PRA by means of a merger whereby Indigo Merger Sub, Inc., a 
Delaware corporation and subsidiary of the Company, merged with and into PRA, the parent of the PRA Health Sciences 
Group.  Upon  completion  of  the  Merger,  pursuant  to  the  terms  of  the  Merger  Agreement,  PRA  became  a  wholly  owned 
subsidiary  of  the  Company.  The  transaction  resulted  in  the  issuance  of  27,372,427  shares  to  the  former  stockholders  of 

107

 
 
 
 
 
 
 
Notes to Consolidated Financial Statements (continued)
for the year ended 31 December 2022

25.  Capital and reserves (continued)

PRA. The Company issued these shares at the prevailing market price and recognised the premium of $5,656.2 million on 
issuance of these shares as a merger reserve as required under Irish Company Law.

Retained earnings
In  addition  to  the  profit  for  the  financial  year  the  Group  has  also  recognised  the  re-measurement  of  the  defined  benefit 
pension  scheme  in  this  reserve.  In  2022,  the  Group  recognised  a  re-measurement  gain  on  the  defined  benefit  pension 
scheme of $13.3 million (31 December 2021: a re-measurement gain of $4.2 million). In 2022, the Group recognised share 
issue  costs  of  $0.0  million  in  this  reserve  (2021:  $0.9  million). The  Group  has  recognised  a  credit  of $71.7  million  (2021: 
credit of $162 million) in respect of exercised and expired share-based awards that have been transferred from the share-
based payment reserve. 

A  resolution  was  passed  at  the  Company’s  Annual  General  Meeting  (“AGM”)  on  July  22,  2016,  which  authorized  the 
Directors to purchase (buyback) up to 10% of the outstanding shares in the Company. This authorization was renewed at 
the Company's AGM on each of July 25, 2017, July 24, 2018, July 23, 2019, July 21, 2020, July 20, 2021 and July 26, 2022. 
On 18 February 2022, the Company commenced a further share buyback programme.During the year ended 31 December 
2022, 420,530 ordinary shares were redeemed by the Company for total consideration of $100.0 million

26.  Financial instruments

The  Board  of  Directors  have  overall  responsibility  for  the  establishment  and  oversight  of  the  Group’s  risk  management 
framework. The Group is exposed to various financial risks in the normal course of its business. The principle financial risks 
to which it is exposed include credit risks related to the creditworthiness of its customers and counterparties, with which it 
invests surplus cash funds, liquidity risk associated with the availability of sufficient financial resources to meet liabilities as 
they fall due, foreign currency risks, including both translation and transaction risk, and interest rate risk.

The  Group’s  risk  management  policies  are  established  to  identify  and  analyse  the  risks  faced  by  the  Group,  to  set 
appropriate risk limits and controls, and to monitor risks and adherence to limits. Risk management policies and systems are 
reviewed  regularly  to  reflect  changes  in  market  conditions  and  the  Group’s  activities. The  Group,  through  its  training  and 
management  standards  and  procedures,  aims  to  develop  a  disciplined  and  constructive  control  environment  in  which  all 
employees understand their roles and obligations. The Audit Committee of the Board oversees how management monitors 
compliance with the Group’s risk management policies and procedures and reviews the adequacy of the risk management 
framework in relation to the risks faced by the Group.  

Credit risk 

Credit risk arises from cash and cash equivalents, contractual cash flows of debt investments carried at fair value through 
other comprehensive income and at fair value through profit or loss, favourable derivative financial instruments and deposits 
with banks and financial institutions, as well as credit exposures to customers, including outstanding accounts receivable, 
unbilled receivables and other receivables.  

Credit risk is managed on a group basis. For banks and financial institutions, independently rated parties with a minimum 
rating of BBB+ for overnight maturities and a minimum of A- for any bank deposits greater than overnight and up to three 
months.  

Current  asset  investments  (recorded  at  fair  value  through  other  comprehensive  income)  comprise  investments  with 
maturities  of  greater  than  three  months. The  minimum  ratings  required  for  investment  are  as  follows:  bank  deposits  (A-), 
money market funds (AAA), liquidity funds (AAA) and fixed rate corporate bonds or floating rate notes (A- non-financial, AA- 
financial).  

The Group’s exposure to credit risk arises predominately in respect of the credit risk assessment of customers. Customer 
credit  risk  is  managed  through  application  of  credit  procedures,  in  particular  through  risk  assessment  of  new  customers, 
through  assessment  of  credit  quality,  taking  into  account  its  financial  position,  past  experience  and  other  factors.  The 
compliance with credit terms is regularly monitored by line management.

Contract  terms  may  range  from  several  weeks  to  several  years  depending  on  the  nature  of  the  work  to  be  performed. 
Contracts are generally fixed price or unit based. In most cases, a portion of the contract fee is paid at the time the study or 
trial is started. The balance of the contract fee is generally billable in instalments over the study or trial duration and may be 
based  on  the  delivery  of  certain  performance  targets  or  "milestones"  or  based  on  units  delivered,  or  on  a  fixed  monthly 
payment schedule such as patient enrolment or database delivery.  

Where customers request changes in the scope of a trial or in the services to be provided, a change order or amendment is 
issued which may result either in an increase or decrease in the contract value.

Financial instruments (continued)

The Group also contracts on a "fee-for-service" or "time and materials" basis.  

During the course of a study, the Group will generally incur reimbursable expenses. Reimbursable expenses are typically 
estimated  and  budgeted  within  the  contract  and  are  generally  invoiced  on  a  monthly  basis  based  on  actual  expenses 
incurred.  Reimbursable  expenses  include  payments  to  investigators,  travel  and  accommodation  costs  and  various  other 
expenses incurred over the course of the clinical trial which are fully reimbursable by the client. 

Most of the Group’s contracts are terminable immediately by the customer with justifiable cause or with 30 to 90 days' notice 
without  cause.  In  the  event  of  termination,  the  Group  is  usually  entitled  to  all  sums  owed  for  work  performed  through  the 
notice of termination and certain costs associated with termination of the study. Termination or delay in the performance of a 
contract  occurs  for  various  reasons,  including,  but  not  limited  to,  unexpected  or  undesired  results,  production  problems 
resulting in shortages of the drug, adverse patient reactions to the drug, the client's decision to de-emphasise a particular 
trial, inadequate patient enrolment or investigator recruitment.

The  Group’s  top  five  customers  accounted  for  approximately  28.3%  and  31.6%  of  revenue  during  the  years  ended 
31  December  2022  and  31  December  2021  respectively.  During  the  year  ended  31  December  2022,  8.8%of  the  Group’s 
revenues were derived from its top customer (2021: 8.0%). The addition of new customer accounts, particularly large and 
mid-tier pharma customers and biotech customers have resulted in a reduction in this concentration of revenues from our 
top five customers.

The  maximum  exposure  of  credit  risk  pertaining  to  customers  is  the  carrying  value  of  accounts  receivable  and  unbilled 
revenue  balances.  The  gross  value  of  accounts  receivable  and  unbilled  revenue  balances,  by  geographic  region,  at 
31 December 2022 was as follows:

The Group has four types of financial assets that are subject to the expected credit loss model: 

•
•
•
•

trade receivables (billed amounts) for services provided to customers
unbilled receivables (contract assets) for services provided to customers
other receivables
cash and cash equivalents

Trade receivables, contract assets and other receivables
The Group applies the IFRS 9 simplified approach to measuring expected credit losses which uses a lifetime expected loss 
allowance for all trade receivables and contract assets.  

To measure the expected credit losses, trade receivables and contract assets have been grouped based on shared credit 
risk characteristics and the days past due. The contract assets relate to unbilled work in progress and have substantially the 
same risk characteristics as the trade receivables for the same types of contracts. The Group has therefore concluded that 
the expected loss rates for trade receivables are a reasonable approximation for the loss rates for the contract assets.  

The  expected  loss  rates  are  based  on  the  payment  profiles  of  revenue  over  a  period  of  36  months  before  31  December 
2022.  The  historical  loss  rates  are  adjusted  to  reflect  current  and  forward-looking  information  on  macroeconomic  factors 
affecting the ability of the customers to settle receivables. The group has identified the GDP and the unemployment rate of 
the countries in which it sells its services to be the most relevant factors, and accordingly adjusts the historical loss rates 
based  on  expected  changes  in  these  factors.  See  note  16  -  Accounts  receivable,  unbilled  services  (contract  assets)  and

unearned  revenue  (contract  liabilities)  for  assessment  of  the  allowance  for  credit  losses  for  both  trade  receivables  and 
contract assets. 

Trade  receivables,  other  receivables  and  contract  assets  are  written  off  when  there  is  no  reasonable  expectation  of 
recovery. Indicators that there is no reasonable expectation of recovery include, amongst others, the failure of a debtor to 
engage  in  a  repayment  plan  with  the  group,  and  a  failure  to  make  contractual  payments  for  a  period  of  greater  than  120 
days  past  due.  Impairment  losses  on  trade  receivables,  other  receivables  and  contract  assets  are  presented  as  net 
impairment losses within operating profit. Subsequent recoveries of amounts previously written off are credited against the 
same line item.  

Liquid and capital resources

The  principal  operating  cash  requirements  of  the  Group  include  payment  of  salaries,  office  rents,  travel  expenditures  and 
payments  to  investigators.  Other  cash  requirements  include  capital  expenditures  for  facilities  and  information  system 
enhancements  and  cash  required  to  fund  acquisitions  and  other  growth  opportunities.  The  CRO  industry  is  generally  not 
capital intensive. The Group primarily finances its operations and growth through cash flows from operations, together with 
amounts drawn under negotiated facilities as required. 

The Group’s primary objectives in managing its liquid and capital resources are as follows:

•
•
•

to maintain adequate resources to fund its continued operations,
to ensure availability of sufficient resources to sustain future development and growth of the business, 
to maintain sufficient resources to mitigate risks and unforeseen events which may arise.

The  Group  manages  risks  associated  with  liquid  and  capital  resources  through  ongoing  monitoring  of  actual  and  forecast 
cash  balances  and  by  reviewing  the  existing  and  future  cash  requirements  of  the  business.  It  ensures  that  sufficient 
headroom is available under the Group’s existing negotiated facilities and negotiates additional facilities as required.  Details 
of the Group’s negotiated facilities are set out in note 23 Bank credit lines and loan facilities. 

In  conjunction  with  the  completion  of  the  Merger  Agreement,  on  1  July  2021,  ICON  entered  into  a  credit  agreement 
providing  for  a  senior  secured  term  loan  facility  of  $5,515  million  and  a  senior  secured  revolving  loan  facility  in  an  initial 
aggregate principal amount of $300 million (the "Senior Secured Credit Facilities"). The proceeds of the senior secured term 
loan facility were used to repay the outstanding amount of (i) PRA’s existing credit facilities and (ii) the Company's private 
placement notes outstanding and fund, in part, the Merger. The senior secured term loan facility will mature in July 2028 and 
the revolving loan facility will mature in July 2026. On the 29th of November 2022, the Company agreed with its lenders to 
the early adoption of Term SOFR as the reference rate within the Credit Agreement ahead of the June 2023 USD LIBOR 
cessation  date.  LIBOR  is  no  longer  an  applicable  reference  rate  available  to  the  Company  under  the  terms  of  the  Credit 
Agreement.  

In addition to the Senior Secured Credit Facilities, on 1 July 2021, the Company issued $500.0 million in aggregate principal 
amount of 2.875% senior secured notes due July 2026 (the “Senior Secured Notes”) in a private offering ("the Offering”). 
The Senior Secured Notes will mature on 15 July 2026. The Issuer will pay interest on the Senior Secured Notes on January 
15 and July 15 of each year. Interest on the Senior Secured Notes will accrue at a rate of 2.875% per annum.

interest on senior notes presented separately above and deferred government grants (2022: $42,000 and 2021: $45,000). 

Foreign currency risk
The Group is subject to a number of foreign currency risks given the global nature of its operations. The principal foreign 
currency  risks  to  which  the  business  is  subject  includes  both  foreign  currency  translation  risk  and  foreign  currency 
transaction risk. Although domiciled in Ireland, the Group presents its results in U.S. dollars. As a consequence, the results 
of  non-U.S.  based  operations,  when  translated  into  U.S.  dollars,  could  be  affected  by  fluctuations  in  exchange  rates 
between the U.S. dollar and the currencies of those operations. 
The Group is also subject to foreign currency transaction exposures as the currency in which contracts are priced can be 
different from the currencies in which costs relating to those contracts are incurred. The Group’s operations in the United 
States  are  not  materially  exposed  to  such  currency  differences  as  the  majority  of  revenues  and  costs  are  in  U.S.  dollars. 
However, outside the United States the multinational nature of the Group’s activities means that contracts are usually priced 
in  a  single  currency,  most  often  U.S.  dollars,  Euros  or  pounds  Sterling,  while  costs  arise  in  a  number  of  currencies, 
depending on, among other things, which of the Group’s offices provide staff for the contract and the location of investigator 
sites. 

Although many such contracts benefit from some degree of natural hedging due to the matching of contract revenues and 
costs  in  the  same  currency,  where  costs  are  incurred  in  currencies  other  than  those  in  which  contracts  are  priced, 
fluctuations in the relative value of those currencies could have a material effect on the results of the Group’s operations. 
The  Group  regularly  reviews  its  foreign  currency  exposures  and  usually  negotiates  currency  fluctuation  clauses  in  its 
contracts which allow for price negotiation if certain exchange rate triggers occur.

A  simultaneous  ten  percent  strengthening  or  weakening  of  the  US  Dollar,  Euro  and  Sterling  against  all  other  currencies 
(which  remained  constant)  would  have  increased  or  decreased  profit  by  $37.2  million,  $19.6  million  and  $22.1  million 
respectively  (31  December  2021:  $27.3  million,  $23.1  million  and  $5.9  million  respectively)  as  a  consequence  of  the 
retranslation of foreign currency denominated financial assets and liabilities at those dates. This change in profit is excluding 
the effect of foreign currency denominated long term loans.

Interest rate risk

The Group is exposed to interest rate risk in respect of our cash and cash equivalents and available for sale investments. 
Our  treasury  function  actively  manages  our  available  cash  resources  and  invests  significant  cash  balances  to  ensure 
optimum returns for the Company. Financial instruments are classified either as cash and cash equivalents or available for 
sale investments depending upon the maturity of the related investment. Funds may be invested in the form of floating rate 
notes  and  medium  term  minimum  “A-”  rated  corporate  securities.  We  may  be  subject  to  interest  rate  risk  in  respect  of 
interest rate changes on amounts invested. Interest rate risk is managed by monitoring the composition of the Company’s 
investment portfolio on an ongoing basis having regard to current market interest rates and future trends.

In  conjunction  with  the  completion  of  the  Merger,  on  July  1,  2021,  ICON  entered  into  a  credit  agreement  providing  for  a 
senior secured term loan facility of $5,515 million and a senior secured revolving loan facility in an initial aggregate principal 
amount of $300 million (the "Senior Secured Credit Facilities"). The proceeds of the senior secured term loan facility were 
used to repay the outstanding amount of (i) PRA’s existing credit facilities and (ii) the Company's private placement notes 
outstanding and fund, in part, the Merger. The senior secured term loan facility will mature in July 2028 and the revolving 
loan  facility  will  mature  in  July  2026.  The  credit  agreement  governing  the  Senior  Secured  Credit  Facilities  provides  that 
borrowings denominated in U.S. Dollars will bear interest based on the London Interbank Offered Rate ("LIBOR") or other 
base  rate  (as  elected  by  the  borrower),  plus  an  applicable  margin.  On  November  29,  2022,  the  Company  agreed  with  its 
lenders to the adoption of the Secured Overnight Financing Rate ("SOFR") as the benchmark rate within the Senior Secured 
Credit  Facilities,  thus  LIBOR  is  no  longer  the  benchmark  rate  available  to  the  Company  under  the  terms  of  the  Senior 
Secured Credit Facilities. 

As at the 31 December 2022 the outstanding principal amount of the Senior Secured Term Loan Facility was $4,201 million. 
The  applicable  interest  rate  for  the  next  quarterly  interest  period  is  expected  to  be  7.092%,  Borrowings  under  the  Senior 
Secured Term Loan facility amortise in equal quarterly instalments in an amount equal to 1.00% per annum of the principal 
amount, with the remaining balance due at final maturity. The interest rate margin applicable to borrowings under the senior 
secured term loan facility is USD Term SOFR and a Term SOFR Adjustment depending on the interest period chosen plus 
an applicable margin of 2.25%. The Senior Secured Term Loan Facility is subject to a floor of 0.50%.

In addition to the Senior Secured Facilities, on 1 July 2021, the Company issued $500 million in aggregate principal senior 
notes  due  in  2026  in  a  private  (“the  Offering“). The  Senior  Secured  Notes  will  mature  in  July  2026  and  pay  a  fixed  semi 
annual coupon to investors of 2.875% per annum. This debt is not subject to movements in interest rate conditions.

We regularly evaluate our debt arrangements, as well as market conditions, and we will explore the opportunity to modify 
our  existing  arrangements  or  pursue  additional  financing  arrangements  that  may  result  in  the  issuance  of  new  debt 
securities by us or our affiliates.

Derivatives

The Company has entered into interest rate cap and swap agreements for purposes of managing its exposure to interest 
rate fluctuations. These financial derivative agreements are designated as Cash Flow Hedges.

On  November  29,  2022,  the  Company  entered  into  two  interest  rate  cap  agreements  ("2022  Caps")  with  an  initial  total 
notional  value  of  $2,101  million  to  limit  its  exposure  to  changes  in  the  variable  interest  rate  on  its  Senior  Secured  Credit 
Facilities. Interest on the 2022 Caps began accruing on December 30, 2022 and the interest rate cap expires on December 
31, 2024. The Company pays a fixed rate of 0.42% and receives a variable rate equal to the amount that the three-month 
SOFR rate exceeds 4.75%.

On November 29, 2022, the Company entered into an interest rate swap agreement ("2022 Swap") with an initial notional 
value of $1,101 million to limit its exposure to changes in the variable interest rate on its Senior Secured Credit Facilities. 
Interest on the 2022 Swaps begins accruing on December 31, 2024 and the interest rate swap expires on December 31, 
2026. The Company will pay a fixed rate of 3.4% and receive a variable rate of interest equal to the three-month SOFR on 
the 2022 Swap.

The critical terms of the caps and swap are substantially the same as the underlying borrowings. The interest rate caps and 
swap  are  accounted  for  as  cash  flow  hedges  as  these  transactions  were  executed  to  hedge  the  Company's  interest 
payments  and  for  accounting  purposes  are  considered  highly  effective.  As  such,  the  effective  portion  of  the  hedges  is 
recorded as unrealized gains (losses) on derivatives in Accumulated Other Comprehensive Income.

The  fair  value  of  these  cash  flow  hedges  represents  the  present  value  of  the  anticipated  net  payments  the  Company  will 
make to the counterparty, which, when they occur, are reflected as interest expense on the consolidate statement of income.  

The fair value of the Company’s derivative financial instruments, on a gross basis, and the line items on the accompanying 
consolidate balance sheets to which they were recorded are summarised in the following table:

Financial instruments (continued)

had  no  outstanding  derivative  financial  instruments.  The  Company  recognized  $0.1  million  of  gain  within  OCI  and 
reclassified $0.1 million of gain from OCI to the income statement for the year end December 31, 2022.

Fair values

Certain financial instruments are measured in the Statement of Financial Position at fair value using a fair value hierarchy of 
valuation inputs. The hierarchy prioritises the inputs into three levels based on the extent to which inputs used in measuring 
fair value are observable in the market. Each fair value measurement is reported in one of three levels, which is determined 
by the lowest level input that is significant to the fair value measurement in its entirety. These levels are:

Level 1: 

Inputs are based upon unadjusted quoted prices for identical instruments traded in active markets.

Level 2: 

Inputs are based upon quoted prices for similar instruments in active markets, quoted prices for identical or 
similar  instruments  in  markets  that  are  not  active  and  model-based  valuation  techniques  for  which  all 
significant assumptions are observable in the market or can be corroborated by observable market data for 
substantially the full term of the assets or liabilities.

Level 3: 

Inputs are generally unobservable and typically reflect management’s estimates of assumptions that market 
participants would use in pricing the asset or liability.

The  fair  value  of  financial  assets  together  with  the  carrying  amounts  shown  in  the  Statement  of  Financial  Position  is  as

The carrying values of accounts receivable (less provision for loss), unbilled revenue (contract assets), other current assets, 
cash and cash equivalents  and other non-current assets are carried at amortised cost and assumed to be approximate to 
their fair values due to the short-term nature of these balances. As such their fair values have not been disclosed. 

Current asset investments carried at fair value result in gains or losses being recognised in the Consolidated Statement of 
Comprehensive Income. The fair value of current asset investments is their market price at the financial year end date. They 
are measured on the basis of Level 1 inputs.

Long-term financial assets carried at fair value result in gains or losses being recognised in the Consolidated Statement of 
Comprehensive Income. The fair value of long-term financial assets meet the definition of equity securities without readily 
determinable fair values.  

The carrying values of accounts payable, accrued and other liabilities and provisions (excluding contingent consideration) 
and other non-current liabilities are carried at amortised cost and assumed to be approximate to their fair values.

Each category of asset and liability has remained within the same level of hierarchy as the prior year as there has been no 
change in the extent to which the inputs used in measuring fair value are or are not observable within the market.

The Group is also subject to call and put option arrangements relating to the 51% majority share capital in the equity method 
investment, Oncacare, currently owned by a third-party. The majority investor has the right to sell the 51% majority voting 
share capital exclusively to the Company in a two and half year period, commencing 1 January 2023 and ICON also has the 
right to acquire the 51% majority voting share capital from 1 August 2025. These option arrangements are considered level 
3 financial instruments due to it being necessary to use unobservable inputs in their valuation. The strike price of the options 
was written to closely approximate fair value. 

There have been no transfers between level 1/2 financial instruments and level 3 financial instruments during the current or 
prior financial year.

The  following  table  shows  the  valuation  techniques  used  in  measuring  Level  3  fair  values,  as  well  as  significant 
unobservable inputs used:

Type

Valuation Technique

Long-term financial assets

Call and put option 
arrangements over 51% 
majority share ownership in 
Oncacare is a derivative 
financial instrument

The valuation model is 
based on the NAV of the 
fund as prepared by an 
independent appraiser to 
prepare a fair value 
assessment of 
investment assets each 
year. 
The valuation model is 
based on the financial 
benefit/obligation of the 
Group possessing the 
option to acquire, or 
being faced with the 
option to purchase, the 
shares compared to 
acquiring the shares at 
the market rate.

Significant Unobservable 
Inputs

The interest on the fund 
are not traded on an 
exchange, or data is not 
published in respect of the 
funds. 

Inter-relationship between 
significant unobservable inputs 
and fair value measurement

The valuation is based on the NAV 
of the fund as prepared by an 
independent appraiser. 

The strike price of the 
options are based on an 
earnings multiple which is 
a significant unobservable 
input to the fair value 
calculation.

If the earnings multiple became less 
than the market rate then the fair 
value of the call option asset would 
increase and the fair value of put 
option liability would decrease.

Where  the  Group  enters  into  financial  guarantee  contracts  to  guarantee  the  indebtedness  of  other  companies  within  the 
Group,  the  Group  considers  these  to  be  insurance  arrangements  and  accounts  for  them  as  such.  The  Group  treats  the 
guarantee contract as a contingent liability until such time as it becomes probable that the Group will be required to make a 
payment under that guarantee. As set out in note 23 Bank credit lines and loan facilities, the Senior Secured Credit Facilities 
are guaranteed by ICON plc.

The Company has guaranteed all of the commitments and liabilities referred to in Section 357(1) (b) of the Companies Act in 
respect  of  the  whole  of  the  financial  year  ending  31  December  2022  for  the  subsidiary  companies  listed  below.  These

The  Group  expects  to  spend  approximately  $200  million  in  the  next  12  months  on  further  investments  in  information 
technology. The  Group  believes  that  it  will  be  able  to  fund  additional  foreseeable  cash  needs  for  the  next  twelve  months 
from cash flow from operations and existing cash balances. In the future, the Group may consider acquiring businesses to 
enhance  service  offerings  and  global  presence. Any  such  acquisitions  may  require  additional  external  financing  and  the 
Group may, from time to time, seek to obtain funds from public or private issues of equity or debt securities. There can be no 
assurance that such financing will be available on terms acceptable to the Group.

The  Company  entered  into  subscription  agreements  with  a  number  of  funds  (see  note  18  Financial  asset  investments). 
Capital  totalling  $20.6  million  had  been  advanced  under  the  terms  of  the  subscription  agreements  at  31  December  2022 
(2021:  $16.9  million).  The  Company  had  committed  to  future  investments  of  $23.3  million  in  respect  of  these  funds.  The 
timing of the commitment is not specified in the subscription agreements. 

29.  Litigation

The Group is not party to any litigation or legal proceedings that the Group believes could reasonably be expected to have a 
material adverse effect on the Group’s business, results of operations and financial position. However, from time to time, we 
may become involved in various lawsuits and legal proceedings which arise in the ordinary course of business. Litigation is 
subject to inherent uncertainties, and an adverse result in these or other matters may arise from time to time that may harm 
our business.

 (ii)  Other related party transactions

On  24  July  2020,  a  subsidiary  of  the  Company,  ICON  Clinical  Research  Limited,  entered  into  an  agreement  to  jointly 
establish a new company, Oncacare, with a third-party. The Company has invested $4.9 million to obtain a 49% interest in 
the  voting  share  capital  of  Oncacare.  The  Company  provided  corporate  support  services  to  Oncacare  to  the  value  of 
$451,000  during  the  year  ended  31  December  2022.  $715,000  was  recorded  as  due  from  Oncacare  at  31  December 
2022. During the year ended 31 December 2021, the Company provided a loan of $10.0 million to Oncacare in order to fund 
the continued start up of the business' operations. The loan accrues annual interest at 1.6% and the loan is repayable on 30 
June 2025. The Company has recorded losses of $3.1 million and $2.2 million representing its pro rata share of the losses 
in  Oncacare  during  the  year  ended  31  December  2022  and  December  31,  2021,  respectively.  The  carrying  value  of  the 
Company's investment in Oncacare was reduced by $2.3 million of pro rata losses.  The remaining $0.8 million in pro rata 
losses  served  to  reduce  the  carrying  value  of  the  Company's  loan  receivable  from  Oncacare  from  $10.0  million  to  $9.2 
million. At 31 December 2022  accrued interest of $183,000 remained outstanding.

The majority investor in Oncacare has the right to sell the 51% majority voting share capital exclusively to the Company in a 
two and half year period, commencing 1 January 2023 and ICON also has the right to acquire the 51% majority voting share 
capital from 1 August 2025. On 20 April 2023 the Company acquired the remaining shares of Oncacare from KM Worldwide 
Business LTD for $5.1 million.

31.  Subsequent events

The Company has evaluated subsequent events from the Balance Sheet date through 25 April 2023, the date at which the 
consolidated financial statements were available to be issued.

On  July  24  2020,  a  subsidiary  of  the  Company,  ICON  Clinical  Research  Limited,  entered  into  an  agreement  to  jointly 
establish a new company, Oncacare Limited (Oncacare), a specialized oncology site network in the US and EMEA regions, 
with a third party. The Company has invested $4.9 million to obtain a 49% interest in the voting share capital of Oncacare.  
On  20  April  2023,  the  Company  completed  the  purchase  of  the  majority  investor’s  51%  majority  voting  share  capital  of 
Oncacare. The consideration paid by ICON to purchase the 51% majority voting share capital was $5.1 million. As a result 
of this transaction, Oncacare and its subsidiaries became wholly owned subsidiaries of the ICON Group.

Notes to Company Financial Statements (continued)
for the year ended 31 December 2022

10.  Litigation

The  Company  is  not  party  to  any  litigation  or  other  legal  proceedings  that  the  Company  believes  could  reasonably  be 
expected  to  have  a  material  adverse  effect  on  the  Company’s  business,  results  of  operations  and  financial  position. 
However, from time to time, we may become involved in various lawsuits and legal proceedings which arise in the ordinary 
course of business. Litigation is subject to inherent uncertainties, and an adverse result in these or other matters may arise 
from time to time that may harm our business.

11.  Financial instruments

The  Company  is  exposed  to  various  financial  risks  in  the  normal  course  of  the  business.  The  Company’s  financial 
instruments  typically  comprise  cash  and  accounts  payable. The  main  purpose  of  these  financial  instruments  is  to  provide 
finance  for  the  Company’s  operations.  The  main  risks  arising  from  the  Company’s  financial  instruments  are  credit  risk, 
liquidity risk, foreign exchange risk and interest rate risk.  

Credit risk

Intercompany  loans  receivable  and  payable  are  initially  recognised  at  fair  value.  These  are  subsequently  measured  at 
amortised cost, less any loss allowance. An expected credit loss assessment was performed in respect of the receivables at 
31 December 2021 and 31 December 2022. The identified impairment loss was immaterial.   

Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails to meet its 
contractual obligations. Credit risk in respect of the Company arises on balances due from group companies. As the Group 
is  financially  sound  and  the  subsidiary  entities  that  the  Company  trades  with  are  in  a  position  to  make  payments  as  and 
when they fall due, the Company has assessed the exposure to credit risk as low. 

Liquidity risk 

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due. The Company’s 
liquidity risk arises from the repayment of short-term debt and other obligations as they fall due. The Company minimises 
liquidity risk by ensuring that sufficient cash balances and committed bank lines of credit are available to meet its obligations 
as  they  fall  due.  The  Company’s  bank  credit  lines  and  facilities  are  the  same  as  the  Group.  Details  of  the  Group’s  bank 
credit lines and facilities are set out in note 23 Bank credit lines and loan facilities.

The following table sets out details of the maturity of the Company’s financial liabilities into the relevant maturity groupings 
based on the remaining period from the financial year end date to the contractual maturity date:

Notes to Company Financial Statements (continued)
for the year ended 31 December 2022

11.  Financial instruments (continued)

Foreign currency risk
While the functional currency of the Company is USD, the functional currency of the branches is Euro. As a consequence, 
the results, when translated into U.S. dollars, could be affected by fluctuations in exchange rates against the U.S. dollar.  At 
31 December 2022 the Company had $Nil US dollar denominated bank loans (2021: $Nil).  

Interest rate risk
The  Company  finances  its  operations  through  a  mixture  of  shareholders’  funds,  borrowings  and  working  capital.  The 
Company borrows in required currencies at both fixed and floating interest rates. In general the Company borrows at floating 
rates of interest but may borrow at fixed rates depending on rates available having regard to current market rates and future 
trends. The Company has no external borrowings.    

Fair values
Financial  instruments  are  measured  in  the  Statement  of  Financial  Position  at  fair  value  using  a  fair  value  hierarchy  of 
valuation inputs. The hierarchy prioritises the inputs into three levels based on the extent to which inputs used in measuring 
fair value are observable in the market. Each fair value measurement is reported in one of three levels, which is determined 
by the lowest level input that is significant to the fair value measurement in its entirety. These levels are:

Level 1: 

Inputs are based upon unadjusted quoted prices for identical instruments traded in active markets.

Level 2: 

Inputs are based upon quoted prices for similar instruments in active markets, quoted prices for identical 
or  similar  instruments  in  markets  that  are  not  active  and  model-based  valuation  techniques  for  which  all 
significant assumptions are observable in the market or can be corroborated by observable market data 
for substantially the full term of the assets or liabilities.

Level 3: 

Inputs are generally unobservable and typically reflect management’s estimates of assumptions that 
market participants would use in pricing the asset or liability.

The  carrying  values  of  amounts  due  from  subsidiary  undertakings,  cash  and  cash  equivalents,  other  current  assets, 
accounts payable and accruals and other liabilities are carried at amortised cost and assumed to be approximate to their fair 
values due to the short-term nature of these balances.    

Amounts  owed  by  subsidiary  undertakings  are  non-interest  bearing  and  repayable  on  demand. All  amounts  are  therefore 
recorded as due within one year.  Fair value is deemed to equal carrying value on this basis.  

Each category of asset and liability has remained within the same level of hierarchy as the prior year as there has been no 
change in the extent to which the inputs used in measuring fair value are or are not observable within the market. 

12.  Approval of financial statements

The Board of Directors approved the Company Financial Statements on 25 April 2023.

148

Reconciliation from IFRS to US Accounting Policies

The  Consolidated  Financial  Statements  set  out  on  pages  36 to  135  have  been  prepared  in  accordance  with  International 
Financial Reporting Standards (“IFRS”), as adopted by the European Union (“EU IFRS”), which differ in certain significant 
respects from generally accepted accounting principles applicable in the U.S. (“U.S. GAAP”).  The material differences as 
they apply to the Consolidated Financial Statements are as follows:

(a) Financial statement format

The format of the financial statements and certain note disclosures differ under U.S. GAAP from those under EU IFRS.  The 
Group  prepared  a  U.S.  Securities  and  Exchange  Commission  Form  20-F  Report  which  was  made  available  to  all 
shareholders in February 2023. The financial statements included in such Form 20-F are prepared in accordance with U.S. 
GAAP.

(b) Merger with PRAI

The Group accounts for business combinations under EU IFRS in accordance with the IFRS 3 Business Combinations. As 
permitted  by  IFRS  1  First  Time  Adoption  of  International  Financial  Reporting  Standards  the  Group  has  only  restated 
business  combinations  from  1  June  2001  onwards.  Business  combinations  prior  to  this  date  have  not  been  restated.  In 
addition, goodwill has no longer been amortised since 1 June 2001, but rather is tested annually for impairment.  U.S. GAAP 
adopts different criteria to EU IFRS for establishing the method of accounting to be adopted for business combinations. On 
28 January 2000, the Group completed a transaction with Pacific Research Associates Inc. (“PRAI”), a Group specialising in 
data management, statistical analysis and medical and regulatory consulting based in San Francisco, USA. The merger with 
PRAI was accounted for using acquisition accounting principles in accordance with EU IFRS whilst U.S. GAAP required that 
the merger be accounted for using the pooling-of-interest method of accounting. U.S. GAAP pooling-of-interest accounting 
has resulted in a number of adjustments. Most significantly: 

(i)

the  Group’s  historic  U.S.  GAAP  financial  statements  have  been  restated  to  reflect  the  combined  results  of  ICON 
and PRAI; 
(ii)
the costs of the merger were expensed for U.S. GAAP purposes and included in the cost of acquisition for IFRS;
(iii) goodwill arising on IFRS has been amortised over its expected useful life up to 31 May 2001. No goodwill arose on 

the merger under U.S. GAAP; 

(iv) the  tax  charge  arising  on  the  conversion  of  PRAI  from  an  S-Corporation  to  a  C-Corporation  is  treated  as  a  pre-

acquisition charge under IFRS.

(c) Share-based payment expense

IFRS requires that the fair value of share-based payments be expensed to the Consolidated Statement of Profit and Loss 
over  the  period  the  related  services  are  received,  with  a  corresponding  increase  in  equity.  The  Group  has  accounted  for 
share-based payments under U.S. GAAP in accordance with ASC 718, Compensation – Stock Compensation, which also 
requires that the fair value of share-based payments be expensed to the Consolidated Statement of Profit and Loss over the 
period the related services are received, with a corresponding increase in equity.  

There  is  a  difference  in  recorded  expense  because  firstly,  different  periods  are  in  scope  for  both  treatments  due  to  the 
different  effective  dates  under  both  standards  and  secondly,  due  to  different  models  used  to  calculate  the  fair  value  of 
options. Under U.S. GAAP the Black-Scholes model was used for the calculation of the expense, whereas under IFRS the 
binomial model has been used.

U.S. GAAP requires that the accelerated graded vesting  attribution approach is applied in respect of awards with  straight 
line graded vesting.  IFRS requires that each instalment of an award where there is graded vesting is treated as a separate 
grant  with  a  different  fair  value.  Each  instalment  is  therefore  separately  measured  and  charged  to  the  Consolidated 
Statement of Profit and Loss over the related vesting period.  This results in accelerated expense recognition under IFRS.

(d) Stock-based Compensation Arrangements in a Business Combination

An  exchange  of  share-based  payment  awards  in  a  business  combination  is  treated  as  a  modification  under  IFRS  2. The 
replacement  awards  and  the  original  acquiree  awards  should  both  be  measured  at  fair  value  at  the  acquisition  date  and 
calculated using the fair-value-based measurement principles in IFRS 2. 

U.S.  GAAP  requires  the  attribution  of  compensation  cost  for  the  acquirer’s  replacement  awards  in  the  post-combination 
financial statements to be based on the acquirer’s attribution policy (i.e., straight-line approach or graded-vesting approach). 
Under  IFRS,  however,  the  graded  vesting  approach  is  required  for  all  awards  with  graded  vesting  features  based  on  the 
requirements in IFRS 2.

149

Reconciliation from IFRS to US Accounting Policies (continued)
(e) IAS 19R Defined Benefit Pensions

The Group has recognised the net interest expense of the defined benefit pension scheme within payroll costs (operating 
expenses)  in  the  Consolidated  Statement  of  Profit  and  Loss  under  IAS19R  which  is  consistent  with  the  U.S.  GAAP 
treatment of this cost. Additional net credits related to the defined benefit pension schemes refer to the adjustment required 
to  reverse  the  application  of  the  corridor  approach  permitted  under  U.S.  GAAP  and  the  different  net  interest  expense 
recorded under IFRS and U.S. GAAP.

(f) Current tax and deferred tax assets

Deferred tax asset

U.S.  GAAP, ASC  740,  Income  Taxes  requires  recognition  of  a  deferred  tax  asset  in  respect  of  the  cumulative  amount  of 
compensation cost recognised in the financial statements in respect of unexercised options that will give rise to a future tax 
deduction.  The tax deduction is based on the intrinsic value of the options, with the full tax deduction recorded in profit or 
loss in the year of exercise.  

IFRS also requires that a deferred tax asset is recognised in respect of options not yet exercised where a tax deduction will 
arise.  IAS 12 Income taxes requires that the tax deduction is estimated.  The fair value estimate is based on the share price 
at the exercise date. 

Current tax benefit

U.S.  GAAP,  ASC  740,  Income  Taxes  requires  recognition  of  a  current  tax  benefit  of  certain  tax  deductions  arising  from 
Share-based payment windfall gains in the Consolidated Statement of Operations. IFRS requires that the current tax benefit 
of these Share-based payment windfall gains is recognised through Equity, in the Share-based payment reserve.

(g) IFRS 16 Leases

Under  U.S.  GAAP,  ASC  842  Leases,  lessees  account  for  leases  as  operating  or  finance.  Costs  in  respect  of  operating 
leases are charged to the Consolidated Statement of Operations on a straight-line basis over the lease term. Lease costs 
for all leases under IFRS 16 are comprised of  the depreciation of right-of-use assets and the interest charge in respect of 
the associated lease liability. 

(h) Contract Assets and Contract Liabilities in a Business Combination

In October 2021, the FASB issued ASU 2021-08 "Business Combinations (Topic 805) - Accounting for Contract Assets and 
Contract Liabilities from Contracts with Customers". The amendments in this ASU require that an entity (acquirer) recognise 
and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. At the 
acquisition  date,  an  acquirer  should  account  for  the  related  revenue  contracts  in  accordance  with  Topic  606  as  if  it  had 
originated the contracts. The Company has adopted the amendments in this ASU for year ended 31 December 2021 and 
has applied the amendments of this ASU to the Merger with PRA, completed on 1 July 2021. 

IFRS 3 Business Combinations does not have a similar fair value measurement exception for contract assets and contract 
liabilities. As a result, contract liabilities will be have a lower valuation under IFRS compared to U.S. GAAP with the valuation 
adjustment being charged to revenue over the life of the contract with the customer.

(i) Measurement period adjustments (acquisition accounting)

Under U.S. GAAP, ASC 805 Business Combinations, any adjustments which are made to provisional acquisition accounting 
(i.e., measurement period adjustments) are reflected in the current period. Under IFRS, measurement period adjustments 
are reflected through retrospective application to the period in which the acquisition occurred. As such, measurement period 
adjustments recorded during 2022, in connection with the finalisation of acquisition accounting for the PRA Acquisition, have 
been  applied  retrospectively  for  IFRS  purposes.  Measurement  period  adjustments  primarily  consist  of  final  acquisition 
accounting adjustments to goodwill, intangible assets and the related deferred tax impact.

Appendix A: Risk Factors
Risk Related to Our Business and Operations

The potential loss or delay of our large contracts, or of multiple contracts, could adversely affect our results.

Our clients may discontinue using our services completely or cancel some projects either without notice or upon 
short notice. The termination or delay of a large contract, or of multiple contracts, could have a material adverse effect on 
our revenue and profitability. Historically, clients have canceled or discontinued projects and may in the future cancel their 
contracts with us for reasons including, amongst others:

•
•
•
•
•

the failure of products being tested to satisfy safety or efficacy requirements;
unexpected or undesired clinical results of the product; 
a decision that a particular study is no longer necessary or viable;
poor project performance, quality concerns, insufficient patient enrollment or investigator recruitment; and 
production problems resulting in shortages of the drug.

As a result, contract terminations, delays or other changes are part of our clinical services business. In the event of 
termination,  our  contracts  often  provide  for  fees  for  winding  down  the  trial  but  these  fees  may  not  be  sufficient  for  us  to 
maintain our margins, and termination may result in lower resource utilization rates. In addition, we may not realize the full 
benefits of our unsatisfied performance obligation of contractually committed services if our clients cancel, delay or reduce 
their  commitments  under  our  contracts  with  them.    Therefore,  the  loss,  early  termination  or  delay  of  a  large  contract  or 
contracts could adversely affect our revenues and profitability.  

If we do not generate new business awards, or if new business awards are delayed, terminated, reduced in scope 
or fail to go to contract, our business, financial conditions, results of operations or cash flows may be materially 
adversely affected. 

Our business is dependent on our ability to generate new business awards from new and existing customers and 
maintain existing customer contracts. If we were unable to generate new business awards on a timely basis and contract for 
those awards, that could have a material impact on our business, financial condition, results of operations or cash flows. 

We depend on a limited number of customers and a loss of, or significant decrease in, business from one or more 
of them could affect our business.

While no customers individually contributed more than 10% of our revenues during the years ended December 31, 
2022 and December 31, 2021, our top five customers represented 28.3% and 31.6% of our revenues, respectively. The loss 
of, or a significant decrease in, business from one or more of these key customers could have a material adverse impact on 
our results of operations and financial results. 

The inability of biotechnology customers to raise adequate financing or funding could affect our business.

A portion of our revenue is generated from sales and services to the biotechnology industry. The clients we serve 
are commonly subject to financial pressures, including, but not limited to, the ability to obtain adequate financing or generate 
sufficient funding. To the extent our clients face such pressures, or they change how they utilize our offerings, the demand 
for our services, or the prices our clients are willing to pay for those services, may decline. Any such decline could have a 
material adverse effect on our business, operating results and financial condition.

Our financial results may be adversely impacted if we underprice our contracts, overrun our cost estimates or fail 
to receive approval for, or experience delays in, documenting change orders.

Many of our contracts are long-term fixed price or fixed unit price contracts for services. As a result, variations in 
the timing and progress of large contracts may materially adversely affect our results of operations. Revenue recognized on 
these service contracts are based on an assessment of progress towards completion being the cost of time and other third 
party costs as a percentage of total estimated time and other third party costs to deliver our services. As a result, variations 
in the timing and progress of large contracts may materially adversely affect our results of operations. Estimating time and 
costs to complete requires judgment and includes consideration of the complexity of the study, the number of geographical 
sites  where  trials  are  to  be  conducted  and  the  number  of  patients  to  be  recruited  at  each  site.  We  regularly  review  the 
estimated hours on each contract to determine if the budget accurately reflects the agreed tasks to be performed, taking into 
account the state of progress at the time of review. 

We bear the risk of cost overruns unless the scope of activity is revised from the contract specifications and we are 
able  to  negotiate  a  contract  modification.  We  endeavor  to  ensure  that  any  changes  in  scope  are  appropriately  monitored 
and  change  orders  or  contract  modifications  are  promptly  negotiated  and  documented  for  changes  in  scope.  If  we  fail  to 
successfully negotiate change orders for changes in the resources required or the scope of the work to be performed, and 

154

 
 
 
 
Appendix A: Risk Factors (continued)

the costs of performance of these contracts exceeded their fixed fees, it could materially adversely affect our operations and 
financial results.

If  we  are  unable  to  successfully  develop  and  market  new  services  or  enter  new  markets,  our  growth,  results  of 
operations or financial condition could be adversely affected. 

A key element of our growth strategy is the successful development and marketing of new services or entering new 
markets that complement or expand our existing business.  As we develop new services or enter new markets, we may not 
have  or  be  able  to  adequately  build  the  competencies  necessary  to  perform  such  services  satisfactorily,  may  not  receive 
market  acceptance  for  such  services  or  may  face  increased  competition.  If  we  are  unable  to  succeed  in  developing  new 
services,  entering  new  markets  or  attracting  a  client  base  for  our  new  services  or  in  new  markets,  we  will  be  unable  to 
implement this element of our growth strategy, and our future business, reputation, results of operations could be adversely 
impacted. 

If we fail to attract or retain key personnel, our performance may suffer.

Our business, future success and ability to continue to expand operations depends upon our ability to attract, hire, 
train and retain qualified professional, scientific and technical operating people. We compete for qualified professionals with 
other  Clinical  Research  organisations  (“CROs”),  temporary  staffing  agencies  and  the  in-house  departments  of 
pharmaceutical, biotechnology and medical device companies. An inability to attract and retain a sufficient number of high 
caliber clinical research professionals (in particular, key personnel and executives) at an acceptable cost would impact our 
ability to provide our services, our future performance and results of operations.

We may face challenges retaining employees which could cause disruption to our integration plans and day-to-day 
activities, which may result in additional costs to the business.

The  attraction,  development  and  retention  of  our  talent  is  critical  to  the  success  of  the  Company,  and  we  are 
working  to  strengthen  processes  around  these  areas  to  minimize  retention  risk  and  support  a  successful  integration. The 
Company, led by the Chief Human Resource Officer, is taking meaningful action to retain employees. Through our annual 
Talent  Review  process  we  have  identified  opportunities  for  improvement  as  it  relates  to  employee  retention.  Our  People 
Plans  have  set  specific  goals  for  each  functional  area  in  terms  of  three  critical  areas:  talent  attraction,  development  and 
retention. However, we can provide no assurances that our efforts in this respect will be successful.

Our  leadership  and  talent  programs  contribute  to  the  enhanced  retention  of  our  employees,  better  project 
deliverables for our customers and the enhanced financial performance of the business. We aim to be an industry leader: a 
company  where  talented  people  come  to  do  important  work,  a  place  where  our  employees  can  shape  the  future  of 
healthcare,  grow  their  careers,  and  reach  their  full  potential.  We  have  long  held  a  deep  commitment  to  cultivating  strong 
people practices. This includes competitive total rewards packages along with a focus on continuous learning. Our success 
depends on the knowledge, capabilities, and quality of our people.

Our ability to perform clinical trials is dependent upon the ability to recruit suitable willing patients.

The successful completion of clinical trials is dependent upon the ability to recruit suitable and willing patients on 
which  to  test  the  drug  under  study. The  availability  of  suitable  patients  for  enrollment  in  studies  is  dependent  upon  many 
factors including, amongst others, the size of the patient population, the design of the study protocol, eligibility criteria, the 
referral practices of physicians, the perceived risks and benefits of the drug under study and the availability of alternative 
medication,  including  medication  undergoing  separate  clinical  trials.  Insufficient  or  inappropriate  patient  enrollment  may 
result in the termination or delay of a study which could have a material adverse impact on our results of operations. 

The  Company  is  focused  on  continuing  to  develop  its  expertise  in  patient  recruitment  with  the  establishment  in 
2020 of Accellacare, a global clinical research network, offering patients easier and faster access to innovative treatments 
and offering customers the option to deploy decentralized trials. The focus is on making it easier for the site and the patient 
to  actively  participate  in  a  trial  to  ensure  increased  predictability,  enrollment  and  retention.  Our  site  and  patient  solutions 
group includes upfront planning of site and patient management including identification, enrollment and engagement.  

Improved site selection is achieved through:

•
•
•

leading technology to identify where the patients are that match the protocol;
assessment of the qualification of sites based on real data;
partnerships  with  leading  technology  vendors  and  developing  the  capability  to  enable  EMR  interrogation  into 
clinical  insights  such  as  sub-populations  and  larger  pre-screened  pool  where  the  technology  and  regulations  are 
enabled.  

155

 
Appendix A: Risk Factors (continued)

The  burden  on  the  site,  in  ensuring  patient  enrollment  and  engagement,  is  achieved  through  integrated  site 
networks.  ICON  has  a  number  of  site  alliance  partners.  During  2018,  we  enhanced  our  site  and  patient  recruitment 
capabilities with an expansion of the PMG Research network through a partnership with the DuPage Medical Group. During 
2019,  we  further  enhanced  our  site  and  patient  recruitment  abilities  through  the  strategic  acquisitions  of  MeDiNova  and 
CRN. In 2020, ICON announced the launch of Accellacare, a global clinical research network offering patients easier and 
faster  access  to  innovative  treatments  and  offering  customers  the  option  to  deploy  decentralized  trials.  The  site  network 
includes  previously  acquired  PMG  Research,  MeDiNova  and  CRN. Also  in  2020,  we  entered  into  an  agreement  to  jointly 
establish a new company, Oncacare Limited ("Oncacare"), with a third party. Oncacare operates as a specialized oncology 
site network in the US and EMEA regions. The new site network is focused on implementing a range of commercial models 
with specialist oncology healthcare providers in the US and EMEA, to accelerate the recruitment and retention of patients 
into oncology trials. The oncology site network operates as a joint venture between the Company and a third party company 
which  has  extensive  experience  in  developing  and  running  a  site  network.  We  also  use  digital  solutions  to  drive  site 
performance,  including  pre-screening,  eConsent,  learning  management,  document  tracking  and  management  with  key 
applications.  

Our ability to perform clinical trials is dependent upon our ability to recruit suitable willing investigators.

We  contract  with  physicians  located  in  hospitals,  clinics  or  other  similar  sites,  who  serve  as  investigators  in 
conducting  clinical  trials  to  test  new  drugs  on  their  patients.  Investigators  supervise  administration  of  the  study  drug  to 
patients  during  the  course  of  the  clinical  trial.  The  successful  conduct  of  a  clinical  trial  is  dependent  upon  the  integrity, 
experience and capabilities of the investigators conducting the trial. Insufficient investigator recruitment, which in turn may 
lead to insufficient or inappropriate patient enrollment, may result in the termination or delay of a study which could have a 
material adverse impact on our results of operations.

Climate  change,  extreme  weather  events,  earthquakes  and  other  natural  disasters  could  adversely  affect  our 
business. 

In  recent  years,  extreme  weather  events  and  changing  weather  patterns  such  as  storms,  flooding,  droughts  and 
temperature  changes  have  become  more  common. As  a  result,  we  are  potentially  exposed  to  varying  natural  disaster  or 
extreme weather risks such as hurricanes, tornadoes, droughts or floods, or other events that may result from the impact of 
climate  change  on  the  environment,  such  as  sea  level  rise. As  a  result,  we  could  experience  increased  costs,  business 
interruptions,  destruction  of  facilities,  and  loss  of  life,  all  of  which  could  have  a  material  adverse  effect  on  our  business, 
financial condition, or results of operations. The potential impacts of climate change may also include increased operating 
costs  associated  with  additional  regulatory  requirements  and  investments  in  reducing  energy,  water  use  and  greenhouse 
gas emissions.

A disease outbreak, epidemic or pandemic such as COVID-19, could adversely affect our business performance. 

A disease outbreak, such as influenza or coronavirus, could negatively impact our operations. We could experience 
restrictions on our ability to travel, or the ability of patients or other service providers to travel, to monitor our clinical trials 
and to ensure laboratory samples are collected and analyzed on time as a result of an outbreak. The potential impact of an 
epidemic  or  pandemic  may  also  result  in  increased  operating  costs  and  result  in  a  requirement  to  increase  investment  in 
impact  prevention.  COVID-19  has  affected,  and  may  continue  to  affect,  our  business  performance  and  could  adversely 
affect the economies and financial markets worldwide, resulting in an economic downturn that could impact our business, 
financial condition and results of operations. We may be required, or choose, to take temporary measures intended to help 
minimize  the  risk  of  infection  from  the  virus  for  our  employees,  which  could  negatively  affect  our  business  and  cannot 
presently be predicted with confidence.  

156

Appendix A: Risk Factors (continued)

Our  business  depends  on  the  continued  effectiveness  and  availability  of  our  information  systems,  including  the 
information systems we use to provide our services to our clients, and any system failures of, security breaches of 
or  cyber  attacks  to  these  systems  may  materially  limit  our  operations  or  have  a  material  adverse  effect  on  our 
results of operations. 

Due to the global nature of our business and our reliance on information systems to provide our services, we use 
web-enabled  and  other  integrated  information  systems  in  delivering  our  services.  We  will  continue  to  increase  the  use  of 
these  systems  and  such  systems  will  either  be  developed  internally  or  provided  in  conjunction  with  third  parties.  We  also 
provide access to similar information systems to certain clients in connection with the services we provide them. As the use, 
scope and complexity of our information systems continue to grow, we are exposed to, and will increasingly be exposed to, 
the risks inherent in the development, integration and ongoing operation of evolving information systems, including:

•
•

•

•

disruption or failure of data centers, telecommunications facilities or other key infrastructure platforms;
security breaches, cyber attacks or other failures or malfunctions in our application or information systems or their 
associated  hardware  or  other  systems  that  we  have  access  to,  or  that  we  rely  upon,  or  that  have  access  to  our 
systems; 
security breaches, cyber attacks or malfunctions with key suppliers or partners who we rely on to provide services 
to customers; and
excessive  costs,  excessive  delays  or  other  deficiencies  in,  or  problems  with,  systems  development  and 
deployment.

The  materialization  of  any  of  these  risks  may  impede  our  ability  to  provide  services,  the  processing  of  data,  the 
delivery of databases and services and the day-to-day management of our business and could result in the corruption, loss 
or unauthorized disclosure of proprietary, confidential or other data, as well as reputational harm. 

While we have cybersecurity controls and disaster recovery plans in place, they might not adequately protect us in 
the  event  of  a  system  failure,  security  breach  or  cyber  attack.  To  date,  no  cyber  attacks  have  had  a  material  impact  on 
operations or financial reporting. Additionally, despite any precautions we take, damage from fire, floods, hurricanes, power 
loss, telecommunications failures, computer viruses, information system security breaches, cyber attacks and similar events 
that impact our various computer facilities could result in interruptions in the flow of data to our servers and from our servers 
to our clients. Corruption or loss of data may result in the need to repeat a trial at no cost to the client, but at significant cost 
to  us,  or  result  in  the  termination  of  one  or  more  contracts,  legal  proceedings  or  claims  against  us  or  damage  to  our 
reputation. Additionally, significant delays in system enhancements or inadequate performance of new or upgraded systems 
once completed could damage our reputation and harm our business. Long-term disruptions in the infrastructure caused by 
events such as security breaches, cyber attacks, natural disasters, the outbreak of war, the escalation of hostilities and acts 
of terrorism, particularly involving cities in which we have offices, could adversely affect our business.

Unauthorized disclosure of sensitive or confidential data, whether through system failure or employee negligence, 
fraud  or  misappropriation,  could  damage  our  reputation  and  cause  us  to  lose  clients.  Similarly,  despite  investing  in 
information  and  cybersecurity  controls,  there  is  a  risk  that  unauthorized  access  to  our  information  systems  or  those  we 
develop for our clients, whether by our employees or third parties, including a cyber attack by computer programmers and 
hackers  who  may  attack  ICON  systems,  develop  and  deploy  viruses,  worms,  ransomware  or  other  malicious  software 
programs, could result in negative publicity, significant remediation costs, legal liability, loss of customers and damage to our 
reputation and could have a material adverse effect on our results of operations and financial results. In addition, our liability 
insurance  might  not  be  sufficient  in  type,  the  cover  provided  or  amount  to  adequately  cover  us  against  claims  related  to 
security breaches, cyber attacks and other related breaches. 

Our information systems, and those of third parties which we utilize, may face increased cybersecurity risks due to 
the  COVID-19  pandemic,  including  from  the  significant  number  of  employees  that  are  working  remotely  or  otherwise 
impacted  by  stay-at-home  orders. Additional  remote  access  points  provide  new  potential  vulnerabilities  to  cybercriminals. 
Employees of ICON and third parties may be more susceptible to social engineering efforts, and to phishing attempts which 
can disguise malware as a legitimate effort to circulate important information relating to COVID-19.  

Additionally, ICON completed the Merger with PRA on July 1, 2021 and, as a result, the IT landscape and physical 
footprint of the Company has increased significantly. As the organisation invests in the consolidation of offices, data centers, 
IT systems and business services a significant amount of due diligence has been completed to understand the IT landscape 
and  increased  attack  surface.  While  the  organisation  continues  with  substantial  integration  efforts,  a  failure  to  effectively 
manage these activities in a timely and cost-effective manner may result in disruption to our business and negatively affect 
our operations.

157

 
Appendix A: Risk Factors (continued)

Upgrading the information systems that support our operating processes and evolving the technology platform for 
our services pose risks to our business. 

Continued efficient operation of our business requires that we implement standardized global business processes 
and evolve our information systems to enable this implementation. We have continued to undertake significant programs to 
optimize business processes with respect to our services. A failure to effectively manage the implementation and adapt to 
new processes designed into these new or upgraded systems in a timely and cost-effective manner may result in disruption 
to our business and negatively affect our operations.

We have entered into agreements with certain vendors to provide systems development and integration services 
that develop or license to us the IT platform for programs to optimize our business processes. If such vendors fail to perform 
as  required  or  if  there  are  substantial  delays  in  developing,  implementing  and  updating  the  IT  platform,  our  customer 
delivery  may  be  impaired  and  we  may  have  to  make  substantial  further  investments,  internally  or  with  third  parties,  to 
achieve  our  objectives. Additionally,  our  progress  may  be  limited  by  parties  with  existing  or  claimed  patents  who  seek  to 
prevent us from using preferred technology or seek license payments from us.

Meeting our objectives is dependent on a number of factors which may not take place as we anticipate, including 
obtaining  adequate  technology-enabled  services,  creating  IT-enabled  services  that  our  customers  will  find  desirable  and 
implementing our business model with respect to these services. We are continuing to develop opportunities for automation 
across ICON using state of the art automation tools including Robotic Process Automation (RPA), the development of new 
applications and capabilities, and enabling deeper integration across our digital ecosystem. To remain competitive within our 
industry and keep pace with the rapid evolution of the technological landscape, it is critical that we continue to innovate and 
expand the capabilities of our current technologies. This applies in particular to our ICONIK, Firecrest, ADDPLAN, Integrated 
Dataverse  (IDV®)  and  One  Search  services. Also,  increased  requirements  for  investment  in  information  technology  may 
negatively impact our financial condition, including profitability. 

Failure  to  meet  productivity  objectives  under  our  business  improvement  objectives  could  adversely  impact  our 
competitiveness and therefore our operating results.

We  continue  to  pursue  business  transformation  initiatives  to  embed  technology  and  innovation  and  deliver 
operational efficiencies. As part of these initiatives, we seek to improve our productivity, flexibility, quality, functionality and 
cost  savings  by  our  on-going  investment  in  global  technologies,  continuous  improvement  of  our  business  processes  and 
functions to deliver economies of scale. These initiatives may not deliver their intended gains or be completed in a timely 
manner which may adversely impact our competitiveness and our ability to meet our growth objectives and therefore, could 
adversely affect our business and operating results, including profitability. 

We rely on our interactive response technologies to provide accurate information regarding the randomization of 
patients and the dosage required for patients enrolled in the trials. 

We develop and maintain computer run and web based interactive response technologies to automatically manage 
the randomization of patients in trials, assign the study drug and adjust the dosage when required for patients enrolled in 
trials we support. An error in the design, programming or validation of these systems could lead to inappropriate assignment 
or dosing of patients, which could give rise to patient safety issues and invalidation of the trial and/or liability claims against 
the Company, amongst other things, any of which could have a material effect on our financial condition and operations.

A failure to identify and successfully close and integrate strategic acquisition targets could adversely impact our 
ongoing business and financial results.

We  have  made  a  number  of  acquisitions,  including  the  Merger,  and  continue  to  review  new  acquisition 
opportunities. If we are unable to identify suitable acquisition targets, complete an acquisition or successfully integrate an 
acquired  company  or  business,  our  business  may  be  disrupted.  The  success  of  an  acquisition  will  depend  upon,  among 
other things, our ability to:

effectively and quickly assimilate the operations and services or products of the acquired company or business; 
integrate acquired personnel; 
retain and motivate key employees; 
retain customers; and 

•
•
•
•
• minimize the diversion of management's attention from other business concerns.

In the event that the operations of an acquired company or business do not meet our performance expectations, 
we  may  have  to  restructure  the  acquired  company  or  business  or  write-off  the  value  of  some,  or  all,  of  the  assets  of  the 
acquired company or business.

158

 
 
Appendix A: Risk Factors (continued)

We may be unable to realize anticipated cost and tax synergies and expect to incur substantial expenses related to 
the Merger.

We expect to generate run rate cost synergies of approximately $150 million and tax savings from the combined 
target effective tax rate; both to be realized within approximately four years after completion of the Merger. Since completion 
of the Merger, we have progressed many of our key integration plans including rationalization of our office footprint, targeted 
headcount  reductions  to  improve  efficiency  and  key  system  integrations. The  actions  completed  to  date  are  ahead  of  our 
original plan such that we now anticipate realizing our run rate cost synergies by the end of 2023. Our ability to achieve such 
cost and tax synergies in the timeframe described, is subject to various assumptions by management, which may or may 
not  prove  to  be  accurate,  as  well  as  the  incurrence  of  costs  in  our  operations  that  offset  all  or  a  portion  of  such  cost 
synergies.  As  a  consequence,  we  may  not  be  able  to  realize  all  of  these  cost  and  tax  synergies  within  the  timeframe 
expected.  Failure  to  achieve  the  expected  cost  and  tax  synergies  could  significantly  reduce  the  expected  benefits 
associated with the Merger. 

We  expect  to  continue  to  incur  non-recurring  costs  associated  with  the  combination  of  the  two  companies  and 
achieving the desired cost synergies. These fees and costs have been, and will continue to be, substantial. Such costs, as 
well  as  other  unanticipated  costs  and  expenses,  could  have  a  material  adverse  effect  on  our  financial  condition  and 
operating results.

Improper performance of our services could adversely impact our reputation and our financial results.

The  performance  of  clinical  development  services  is  complex  and  time-consuming.  We  may  make  mistakes  in 
conducting a clinical trial that could negatively impact or damage the usefulness of the clinical trial or cause the results to be 
reported improperly.  If the clinical trial results are compromised, we could be subject to significant costs or liability, which 
could have an adverse impact on our ability to perform our services. Large clinical trials are costly, and while we endeavor to 
contractually  limit  our  exposure  to  such  risks,  improper  performance  of  our  services  could  have  an  adverse  effect  on  our 
financial  condition,  damage  our  reputation  and  result  in  the  cancellation  of  current  contracts  or  failure  to  obtain  new 
contracts from affected or other clients. 

Our  relationships  with  existing  or  potential  customers  who  are  in  competition  with  each  other  may  adversely 
impact the degree to which other customers or potential customers use our services, which may adversely affect 
our results of operations.

The biopharmaceutical industry is highly competitive, with biopharmaceutical companies each seeking to persuade 
payers,  providers  and  patients  that  their  drug  therapies  are  better  and  more  cost-effective  than  competing  therapies 
marketed  or  being  developed  by  competing  companies.  In  addition  to  the  adverse  competitive  interests  that 
biopharmaceutical companies have with each other, biopharmaceutical companies also have adverse interests with respect 
to  drug  selection  and  reimbursement  with  other  participants  in  the  healthcare  industry,  including  payers  and  providers. 
Biopharmaceutical companies also compete to be first to market with new drug therapies. We regularly provide services to 
biopharmaceutical  companies  who  compete  with  each  other  and  we  sometimes  provide  services  to  such  customers 
regarding competing drugs in development. Our existing or future relationships with our biopharmaceutical customers may 
therefore deter other biopharmaceutical customers from using our services or may result in our customers seeking to place 
limits on our ability to serve other biopharmaceutical industry participants. In addition, our further expansion into the broader 
healthcare market may adversely impact our relationships with biopharmaceutical customers and such customers may elect 
not to use our services, reduce the scope of services that we provide to them or seek to place restrictions on our ability to 
serve  customers  in  the  broader  healthcare  market  with  interests  that  are  adverse  to  theirs.  Any  loss  of  customers  or 
reductions  in  the  level  of  revenues  from  a  customer  could  have  a  material  adverse  effect  on  our  results  of  operations, 
business and prospects.

159

Appendix A: Risk Factors (continued)

We  have  only  a  limited  ability  to  protect  our  intellectual  property  rights  and  these  rights  are  important  to  our 
success.

Our  success  depends,  in  part,  upon  our  ability  to  develop,  use  and  protect  our  proprietary  methodologies, 
analytics, systems, technologies and other intellectual property. Existing laws of the various countries in which we provide 
services or solutions offer only limited protection of our intellectual property rights, and the protection in some countries may 
be very limited. We rely upon a combination of trade secrets, confidentiality policies, non-disclosure, invention assignment 
and  other  contractual  arrangements  and  patent,  copyright  and  trademark  laws,  to  protect  our  intellectual  property  rights. 
These  laws  are  subject  to  change  at  any  time  and  certain  agreements  may  not  be  fully  enforceable,  which  could  further 
restrict  our  ability  to  protect  our  innovations.  Intellectual  property  rights  may  not  prevent  competitors  from  independently 
developing  services  similar  to,  or  duplicative  of,  ours.  Further,  the  steps  we  take  in  this  regard  might  not  be  adequate  to 
prevent  or  deter  infringement  or  other  misappropriation  of  our  intellectual  property  by  competitors,  former  employees  or 
other third parties and we might not be able to detect unauthorized use of, or take appropriate and timely steps to enforce 
our intellectual property rights. Enforcing our rights might also require considerable time, money and oversight and we may 
not be successful in enforcing our rights.

The  biopharmaceutical  industry  has  a  history  of  patent  and  other  intellectual  property  litigation  and  we  might  be 
involved in costly intellectual property lawsuits.

The biopharmaceutical industry has a history of intellectual property litigation, and these lawsuits will likely continue 
in  the  future. Accordingly,  we  may  face  patent  infringement  legal  proceedings  by  companies  that  have  patents  for  similar 
business processes or other legal proceedings alleging infringement of their intellectual property rights. Legal proceedings 
relating  to  intellectual  property  could  be  expensive,  take  significant  time  and  divert  management’s  attention  from  other 
business concerns, regardless of the outcome of the litigation. If we do not prevail in an infringement lawsuit brought against 
us, we might have to pay substantial damages and we could be required to stop the infringing activity or obtain a license to 
use technology on unfavorable terms. Any infringement or other legal processing related to intellectual property could have 
a material adverse effect on our operations and financial condition.

We act as authorized representative or legal representative for some clients pursuant to certain jurisdictional 
requirements for sponsors of clinical trials to appoint an authorized representative or legal representative with a 
local presence within the relevant jurisdiction. 

We act as authorized representative pursuant to Medical Devices Directive 93/42/EEC (“MDD”),  Medical Devices 
Regulation 2017/745 (“MDR”) and Active Implantable Medical Devices Directive 90/385/EEC (“AIMD”) for certain clients who 
are located outside of the European Union. As authorized representative, we act on behalf of medical device manufacturers 
in relation to specified tasks with regard to their obligations under MDR. 

We  also  act  as  legal  representative  pursuant  to  European  Clinical  Trials  Directive  (2021/20/EC)  (“CTD”),  EU 
Clinical Trials Regulation (No.536/2014) (“CTR”), MDD, MDR and AIMD, for certain clients who are located outside of the 
European  Union  with  respect  to  clinical  trials  being  carried  out  by  those  clients  in  the  European  Union.  We  also  perform 
similar  legal  representative  services  for  certain  clients  in  other  non-EU  jurisdictions  where  client  is  located  outside  the 
relevant  local  jurisdiction,  ICON  has  an  established  local  legal  entity  and  analogous  local  regulations  have  a  similar 
requirement for a local legal representative for clinical trials being carried out in those jurisdictions. As legal representative, 
we are responsible for ensuring compliance with the client’s obligations pursuant to CTD, CTR and MDR or analogous local 
legislation  and  we  are  the  addressee  for  all  communications  with  the  client  provided  for  under  CTD,  CTR  and  MDR  or 
analogous local legislation.

We  provide  these  services  subject  to  certain  terms  and  conditions  which  are  contained  in  our  agreements  with 
clients  pertaining  to  these  services.  We  aim  to  reduce  any  potential  liability  associated  with  these  activities  by  seeking 
contractual indemnification from our clients and by maintaining an appropriate level of insurance cover. However, there is no 
guarantee that the specific insurance will be available or that a client will fulfill its obligations in relation to their indemnity.

We  rely  on  third  parties  to  provide  certain  data  and  other  information  to  us.  Our  suppliers  or  providers  might 
increase our cost to obtain, restrict our use of or refuse to license data, which could lead to our inability to access 
certain data or provide certain services and, as a result, materially and adversely affect our operating results and 
financial condition.

Our  services  are  derived  from,  or  include,  the  use  of  data  we  collect  from  third  parties.  We  have  several  data 

suppliers that provide us with a broad and diverse scope of information that we collect, use in our business and sell.

We generally enter into long-term contractual arrangements with many of our data suppliers. At the time we enter 
into a new data supply contract or renew an existing contract, suppliers may increase our cost to obtain and use the data 
provided by such supplier, increase restrictions on our ability to use or sell such data, or altogether refuse to license the data 

160

Appendix A: Risk Factors (continued)

to us. Also, our data suppliers may fail to meet or adhere to our quality control standards or fail to deliver the data to us. 
Although no single supplier is material to our business, if suppliers that collectively provide a significant amount of the data 
we receive or use were to increase our costs to obtain or use such data, further restrict our access to or use of such data, 
fail to meet or adhere to our quality control standards, refuse to provide or fail to deliver data to us, our ability to provide 
data-dependent  services  to  our  clients  may  be  adversely  impacted,  which  could  have  a  material  adverse  effect  on  our 
business, results of operations, financial condition or cash flow.

We  rely  on  third  parties  for  important  products,  services  and  licenses  to  certain  technology  and  intellectual 
property  rights.  If  there  was  failure  in  delivery  by  these  parties,  we  might  not  be  able  to  continue  to  obtain  such 
products, services and licenses.

We depend on certain third parties to provide us with products and services critical to our business. Such services 
include,  among  others,  suppliers  of  drugs  for  patients  participating  in  trials,  suppliers  of  kits  for  use  in  our  laboratories, 
suppliers of reagents for use in our testing equipment and providers of maintenance services for our equipment. The failure 
of  any  of  these  third  parties  to  adequately  provide  the  required  products  or  services,  or  to  do  so  in  compliance  with 
applicable regulatory requirements, could have a material adverse effect on our business.

Some of our services rely on intellectual property, technology and other similar property owned and/or controlled by 
third  parties.  Our  licenses  to  this  property  and  technology  could  terminate  or  expire  and  we  might  not  be  able  to  replace 
these  licenses  in  a  timely  manner. Also,  we  might  not  be  able  to  renew  these  licenses  on  similar  terms  and  conditions. 
Failure to renew these licenses, or renewals of these licenses on less advantageous terms, could have a material adverse 
effect on our business, results of operations, financial condition or cash flow.

Risk Related to Our Industry

Outsourcing trends in the pharmaceutical, biotechnology and medical device industries and changes in spending 
on research and development could adversely affect our operating results and growth rates.

We  are  dependent  upon  the  ability  and  willingness  of  the  pharmaceutical,  biotechnology  and  medical  device 
companies  to  continue  to  spend  on  research  and  development  and  to  outsource  the  services  that  we  provide.  We  are 
therefore subject to risks, uncertainties and trends that affect companies in these industries that we do not control. We have 
benefited to date from the tendency of pharmaceutical, biotechnology and medical device companies to outsource clinical 
research projects. Any downturn in these industries or reduction in spending or outsourcing could materially adversely affect 
our business. The following could each result in such a downturn:

•

•

•

if  pharmaceutical,  biotechnology  or  medical  device  companies  expanded  upon  their  in-house  clinical  or 
development capabilities, they would be less likely to utilize our services;
if governmental regulations were changed, it could affect the ability of our clients to operate profitably, which may 
lead to a decrease in research spending and therefore this could have a material adverse effect on our business; 
and
if unfavorable economic conditions or disruptions in the credit and capital markets negatively impacted our clients.

Large  pharmaceutical  companies  are  increasingly  consolidating  their  vendor  base  and  entering  strategic 
partnership arrangements with a limited number of outsource providers.

Large  pharmaceutical  companies  are  continually  seeking  to  drive  efficiencies  in  their  development  processes  to 
both reduce costs associated with the development of new drug candidates and accelerate time to market. As a result, large 
pharmaceutical  companies,  in  particular,  are  increasingly  looking  to  consolidate  the  number  of  outsource  providers  with 
which  they  engage,  with  many  entering  strategic  partnership  arrangements  with  a  limited  number  of  outsource 
providers.  The  failure  to  enter  strategic  partnership  arrangements  with  customers  or  the  loss  of  existing  customers  as  a 
result of them entering strategic partnership arrangements with our competitors could have a material adverse impact on our 
results of operations.

Increased  collaboration  amongst  pharmaceutical  companies  in  research  and  development  activities  may  lead  to 
fewer research opportunities.

Certain  pharmaceutical  companies  have  begun  to  collaborate  in  seeking  to  develop  new  drug  candidates. 
Increased  collaboration  amongst  pharmaceutical  companies  may  lead  to  fewer  research  opportunities,  which  in  turn  may 
lead  to  fewer  outsource  opportunities  for  companies  within  the  CRO  industry. A  reduction  in  outsource  opportunities  as  a 
result of this increased collaboration could have a material adverse impact on our results of operations.

We operate in a highly competitive and dynamic market.

161

 
Appendix A: Risk Factors (continued)

The  CRO  industry  is  highly  competitive.  In  particular,  we  compete  with  other  large  global  CROs  for  strategic 
relationships with large pharmaceutical companies. If we are unable to retain and renew existing strategic relationships and 
win new strategic relationships, there could be a material adverse impact on our results. Similarly, we compete with other 
CROs for work which comes outside of these strategic relationships and being unable to win work outside of these strategic 
relationships would have a material adverse impact on our results.

The type and depth of services provided by CROs has changed in recent years. Failure to develop and market new 

services or expand existing service offerings could adversely affect our business and operations.

New entrants may also enter the market which would further increase competition and could adversely affect our 

business and operations.

We may be adversely affected by industry, customer or therapeutic concentration.

We  provide  services  to  biopharmaceutical,  biotechnology,  medical  device  and  government  organisations  and  our 
revenue  is  dependent  on  expenditures  by  these  customers.    Our  business  could  therefore  be  adversely  impacted  by 
mergers, consolidation, business failures, distress in financial markets or other factors resulting in a decrease in the number 
of  potential  customers  or  therapeutic  products  being  developed  through  the  drug  development  progress. There  has  been 
consolidation in the biopharmaceutical market in recent years. If the number of our potential customers were to decline in 
the future, they may be able to negotiate price discounts or other terms for services that are less favorable to us than they 
have been historically. 

Risk Related to Our Financial Results and Financial Position

Our quarterly results are dependent upon a number of factors and can fluctuate from quarter to quarter. They may 
fall  short  of  prior  periods,  our  projections  or  the  expectations  of  securities  analysts  or  investors,  which  may 
adversely affect the market price of our stock.  

Our results of operations in any quarter can fluctuate or differ from expected or forecast results depending upon or 
due  to,  among  other  things,  the  number  and  scope  of  ongoing  client  projects,  the  commencement,  postponement, 
variation, cancellation or termination of projects in a quarter, the mix of activity, cost overruns, employee hiring, employee 
attrition and other factors. Our revenue in any period is directly related to the number of employees who were working on 
billable projects together with investigator activity during that period. We may be unable to compensate for periods of under-
utilization during one part of a fiscal period by earning revenue during another part of that period. We believe that operating 
results for any particular quarter are not necessarily a meaningful indicator of future results.

Also,  if  in  future  quarters,  we  are  unable  to  continue  to  deliver  operational  efficiencies  and  our  expenses  grow 
faster  than  our  revenues,  our  operating  margins,  profitability  and  overall  financial  condition  may  be  materially  adversely 
impacted.

Our exposure to exchange rate fluctuations could adversely affect our future results of operations.

Our  contracts  with  clients  are  sometimes  denominated  in  currencies  other  than  the  currency  in  which  we  incur 
expenses  related  to  such  contracts.  Where  expenses  are  incurred  in  currencies  other  than  those  in  which  contracts  are 
priced,  fluctuations  in  the  relative  value  of  those  currencies  could  have  a  material  adverse  effect  on  our  results  of 
operations.

In addition, we are also subject to translation exposures as our consolidated financial results are presented in U.S. 
dollars,  while  the  local  results  of  a  certain  number  of  our  subsidiaries  are  prepared  in  currencies  other  than  U.S.  dollars, 
including, amongst others, the pound sterling and the euro. Accordingly, changes in exchange rates between the U.S. dollar 
and those other currencies will affect the translation of subsidiary companies' financial results into U.S. dollars in reporting 
our consolidated financial results.

162

Appendix A: Risk Factors (continued)

Inflation and rising labor costs could adversely affect our future results of operations.

Inflation and rising labor costs may result in significant increases to the cost of our services, which we may not be 
able  to  recover  from  our  customers.  Our  contracts  with  clients  are  often  fixed  price  or  fixed  price-per-unit  contracts.  If 
macroeconomic  forces,  such  as  inflation,  cause  the  cost  of  inputs  required  to  deliver  these  contracts  to  increase 
significantly, we may be unable to pass along these cost to our customers. A sustained increase in these costs may require 
us to increase the price of future service offerings. These actions could adversely affect our future revenue, gross margin, or 
both.

Our effective tax rate may fluctuate from quarter-to-quarter, which may adversely affect our results of operations. 

Our  quarterly  effective  tax  rate  has  depended  and  will  continue  to  depend  on  the  geographic  distribution  of  our 
taxable  earnings  amongst  the  multiple  tax  jurisdictions  (such  as  Ireland,  United  States  and  United  Kingdom)  in  which  we 
operate  and  the  tax  law  in  those  jurisdictions.  Changes  in  the  geographic  mix  of  our  results  of  operations  amongst  these 
jurisdictions  may  have  a  significant  impact  on  our  effective  tax  rate  from  quarter-to-quarter.  Changes  in  tax  law  in  one  or 
more jurisdictions could also have a significant impact on our tax rate and results. In addition, as we operate in multiple tax 
jurisdictions,  we  may  be  subject  to  audits  in  certain  jurisdictions.  These  audits  may  involve  complex  issues  which  could 
require an extended time period before being resolved. The resolution of audit issues may lead to additional taxes, interest 
as well as fines and/or penalties being imposed which could have a material adverse impact on our effective tax rate and 
our consolidated financial results. 

Our unsatisfied performance obligation may not convert to revenue and the rate of conversion may slow.

Our unsatisfied performance obligation is the amount of awards that has not yet converted to revenue. This value 
is  not  necessarily  a  meaningful  predictor  of  future  results  due  to  the  potential  for  the  cancellation  or  delay  of  projects 
included  in  the  unsatisfied  performance  obligation.  No  assurances  can  be  given  that  we  will  be  able  to  realize  this 
unsatisfied performance obligation in full as revenue. A failure to realize these awards could have a material adverse impact 
on our results of operations. In addition, as the length and complexity of projects increases, the rate at which awards convert 
to revenue may be slower than in the past. A significant reduction in the rate of conversion could have a material impact on 
our results of operations.

The Company is exposed to various risks in relation to our cash and cash equivalents and short term investments.

The Company’s treasury function manages our available cash resources and invests significant cash balances in 
various financial institutions to try to ensure optimum returns for our surplus cash balances. These balances are classified 
as  cash  and  cash  equivalents  or  short  term  investments  depending  on  the  maturity  of  the  related  investment.  Cash  and 
cash  equivalents  comprise  cash  and  highly  liquid  investments  with  maturities  of  three  months  or  less.  Short  term 
investments comprise highly liquid investments with maturities of greater than three months and minimum “A-” rated fixed 
and floating rate securities.

Given  the  global  nature  of  our  business,  we  are  exposed  to  various  risks  in  relation  to  these  balances  including 
liquidity risk, credit risk associated with the counterparties with whom we invest, interest rate risk on floating rate securities, 
sovereign risk (our principle sovereign risk relates to investments in U.S. Treasury funds) and other factors.

Although  we  have  not  recognized  any  significant  losses  to  date  on  our  cash  and  cash  equivalents  or  short  term 
investments,  any  significant  declines  in  their  market  values  could  have  a  material  adverse  effect  on  our  financial  position 
and operating results.

Changes in accounting standards may adversely affect our financial statements. 

We  prepare  our  financial  statements  in  accordance  with  generally  accepted  accounting  principles  in  the  United 
States of America ("US GAAP") which are revised on an on-going basis by the authoritative bodies. It is possible that future 
accounting standard updates may require changes to the accounting treatment that we apply in preparation of our financial 
statements.  These  changes  may  also  require  significant  changes  to  our  reporting  systems.  These  updates  may  result  in 
unexpected variability in the timing of recognition of revenue or expenses and therefore in our operating results. 

Risk Related to Our Indebtedness

We  have  incurred  substantial  additional  indebtedness  in  connection  with  the  Merger,  which  could  impair  our 
flexibility and access to capital and could adversely affect the combined Company’s business, financial condition 
or results of operations.

163

 
 
   
Appendix A: Risk Factors (continued)

Following completion of the Merger and the other transactions contemplated by the Merger Agreement, the Company has a 
substantial  amount  of  debt.  ICON  borrowed  approximately  $6,015  million  in  order  to  pay  PRA  stockholders  the  cash 
consideration due to them as merger consideration under the Merger Agreement, pay related fees and transaction costs in 
connection with the transactions, and refinance existing indebtedness. The total remaining transaction related debt balance 
at 31 December 2022 was $4,701 million. This level of borrowings could adversely affect the Company in a number of ways, 
including, but not limited to, by placing us at a competitive disadvantage compared to our competitors that have less debt, 
causing us to incur substantial fees from time to time in connection with debt amendments or refinancing, making it more 
difficult  for  the  Company  to  satisfy  its  obligations  with  respect  to  its  debt  or  to  its  trade  or  other  creditors,  requiring  a 
substantial  portion  of  the  Company’s  cash  flows  from  operations  for  the  payment  of  interest  on  the  Company’s  debt, 
reducing the Company’s flexibility to respond to changing business and economic conditions, and reducing funds available 
for  the  Company’s  investments  in  research  and  development,  capital  expenditures  and  other  activities.  If  ICON  cannot 
service its debt, it may have to take actions such as selling assets, seeking additional debt or equity, or reducing or delaying 
capital expenditures, strategic acquisitions, investments and alliances.

In  addition,  ICON’s  increased  level  of  indebtedness  could  adversely  affect  ICON’s  credit  rating,  which  could  result  in 
increased borrowing costs for the Company in the future. No assurances can be made that ICON will be able to refinance 
any indebtedness incurred in connection with the Merger on terms acceptable to it or at all.

Covenants  in  our  credit  agreement  and  the  indenture  governing  the  Senior  Secured  Notes  may  restrict  our 
business and operations. Our financial condition and results of operations could be adversely affected if we do not 
comply with those covenants.

The Senior Secured Credit Facilities and the indenture include certain customary covenants that limit our ability to, amongst 
other things, subject to certain exceptions:

• make dividends, investments and other restricted payments;
•
•
•
•
•

enter into sale and leaseback transactions;
engage in share buybacks;
incur or assume liens or additional debt;
engage in mergers or reorganisations; or
enter into certain types of transactions with affiliates.

The  revolving  credit  facility  also  includes  a  financial  covenant  that  requires  us  to  comply  with  a  maximum  consolidated 
leverage ratio. Our ability to comply with this financial covenant may be affected by events beyond our control.

Interest rate fluctuations may materially adversely affect our results of operations and financial conditions due to 
the variable interest rate on our senior secured term loan facility, our revolving credit facility or in respect of any 
future issuances of debt.

Borrowings under the senior secured term loan facility amortise in equal quarterly installments in an amount equal to 1.00% 
per  annum  of  the  original  principal  amount,  with  the  remaining  balance  due  at  final  maturity.  The  interest  rate  margin 
applicable  to  borrowings  under  the  senior  secured  term  loan  facility  is  USD  Term  SOFR  and  a  Term  SOFR  Adjustment 
depending on the interest period chosen plus an applicable margin of 2.25%. The senior secured term loan facility is subject 
to a floor of 0.50%. 

The interest rate margin applicable to borrowings under the revolving loan facility will be, at the option of the borrower, either 
(i) the applicable base rate plus an applicable margin of 1.00%, 0.60% or 0.25% based on ICON’s current corporate family 
rating  assigned  by  S&P  of  BB-  (or  lower),  BB  or  BB+  (or  higher),  respectively,  or  (ii)  Term  SOFR  plus  a  Term  SOFR 
Adjustment  on  the  interest  period  chosen  plus  an  applicable  margin  of 2.00%,  1.60%  or  1.25%  based  on  ICON’s  current 
corporate family rating assigned by S&P of BB- (or lower), BB or BB+ (or higher), respectively. In addition, lenders under the 
revolving loan facility are entitled to commitment fees as a percentage of the applicable margin at the time of drawing and 
utilization fees dependent on the proportion of the facility drawn. At 31 December 2022, no amounts were outstanding under 
the  revolving  loan  facility  with  the  exception  of  $4.5  million  letters  of  credit  given  to  landlords  to  guarantee  lease 
arrangements.

164

Appendix A: Risk Factors (continued)

Because  the  Company  has  variable  rate  debt,  fluctuations  in  interest  rates  affect  our  business.    We  attempt  to  minimize 
interest  rate  risk  and  lower  our  overall  borrowing  costs  through  the  utilization  of  interest  rate  cap  and  interest  rate  swap 
derivative  financial  instruments.    We  have  entered  into  certain  interest  rate  cap  and  interest  rate  swap  agreements  with 
three  financial  institutions  with  respect  to  a  portion  of  our  outstanding  debt.    Accordingly,  any  change  in  market  value 
associated  with  these  agreements  is  offset  by  the  opposite  market  impact  on  the  portion  of  the  debt  covered  by  such 
agreements. See Note 14 - Derivatives.

Borrowings under our Senior Secured Credit Facilities bear interest at a variable rate that is based on the Secured 
Overnight Financing Rate (“SOFR”), which may have consequences for us that cannot be reasonably predicted and 
may adversely affect our liquidity, financial condition, and results of operations.

On  July  27,  2017,  the  U.K.  Financial  Conduct Authority  (the  “FCA”)  announced  that  it  intended  to  end  the  use  of  LIBOR 
effective after December 31, 2021 as the benchmark rate that many banks and issuers use to set interest rates for loans, 
securities,  derivative  contracts  and  other  financial  instruments.  Recognizing  the  need  to  replace  LIBOR,  authorities  in  the 
United States convened the Alternative Reference Rates Committee (“ARRC”) in 2014 to identify a replacement for LIBOR 
with  respect  to  indebtedness  denominated  in  U.S.  Dollars.  In  2017,  the  ARRC  identified  SOFR,  and  in  April  2018,  the 
Federal Reserve Bank of New York began publishing SOFR. 

SOFR  is  a  measure  of  the  cost  of  borrowing  cash  overnight,  collateralized  by  U.S.  Treasury  securities,  and  is  based  on 
directly  observable  U.S.  Treasury-backed  repurchase  transactions.  Although  the  U.S.  Treasury-backed  overnight  repo 
market is highly liquid, there is currently no robust market for determining forward-looking SOFR term rates. Because SOFR 
is an overnight risk-free rate, whereas LIBOR has various terms and an embedded credit charge, the transition from LIBOR 
to SOFR will require adjustments, which may continue to vary for certain forms of indebtedness and financial instruments as 
the  relevant  markets  adapt  to  SOFR’s  implementation.  Similar  alternative  benchmark  replacements  will  be  required  to  be 
implemented  in  respect  of  indebtedness  and  other  financial  instruments  that  are  currently  based  on  LIBOR  quotes  for 
currencies other than the U.S. Dollar.  

The credit agreement governing the Senior Secured Credit Facilities provides that borrowings denominated in U.S. Dollars 
will bear interest based on LIBOR or other base rate (as elected by the borrower), plus an applicable margin.  The credit 
agreement  also  provides  that  LIBOR  may  be  replaced  by  a  SOFR-based  rate  for  borrowings  in  U.S.  Dollars  upon  (i)  the 
FCA ceasing to provide LIBOR for U.S. Dollars or announcing that LIBOR is no longer representative or (ii) an early election 
by  the  Company  and  the  administrative  agent  under  our  credit  agreement  to  transition  from  LIBOR.    On  November  29, 
2022, the Company agreed with its lenders to the adoption of SOFR as the benchmark rate within the Credit Agreement.  
The possible volatility of and uncertainty around SOFR as a LIBOR replacement rate and the applicable credit adjustment 
could  result  in  higher  borrowing  costs  for  us,  which  would  adversely  affect  our  liquidity,  financial  condition,  and  results  of 
operations.

Risk Related to Political, Legal or Regulatory Environment

We  may  lose  business  opportunities  as  a  result  of  healthcare  reform  and  the  expansion  of  managed  care 
organisations.

Numerous  governments,  including  the  U.S.  government,  have  undertaken  efforts  to  control  growing  healthcare 
costs  through  legislation,  regulation  and  voluntary  agreements  with  medical  care  providers  and  drug  companies.  If  these 
efforts  are  successful,  pharmaceutical,  biotechnology  and  medical  device  companies  may  react  by  spending  less  on 
research and development and therefore this could have a material adverse effect on our business.

In addition to healthcare reform proposals, the expansion of managed care organisations in the health care market 
may result in reduced spending on research and development. Managed care organisations' efforts to cut costs by limiting 
expenditures  on  pharmaceuticals  and  medical  devices  could  result  in  pharmaceutical,  biotechnology  and  medical  device 
companies spending less on research and development. If this were to occur, we would have fewer business opportunities 
and our revenues could decrease, possibly materially.

165

 
Appendix A: Risk Factors (continued)

Healthcare reform legislation, other changes in the healthcare industry and in healthcare spending could adversely 
affect our business model, financial condition or results of operations.

Our results of operations and financial conditions could be affected by changes in healthcare spending and policy.  
The healthcare industry is subject to changing political, regulatory and other influences. It is possible that legislation will be 
introduced and passed in the United States repealing, modifying or invalidating the current healthcare reform legislation, in 
whole  or  in  part,  and  signed  into  law.  Because  of  the  continued  uncertainty  about  the  implementation  of  the  current 
healthcare  reform  legislation,  including  the  potential  for  further  legal  challenges  or  repeal  of  that  legislation,  we  cannot 
quantify  or  predict  with  any  certainty  the  likely  impact  of  the  current  healthcare  reform  legislation  or  its  repeal  on  the 
healthcare sector, on our customers and ultimately on our financial condition or results of operations.

On August 16, 2022, the U.S. government enacted the Inflation Reduction Act of 2022, which, among other things, 
implements a 15% minimum tax on book income of certain large corporations, a 1% excise tax on net stock repurchases 
and several tax incentives to promote clean energy, which will go into effect in 2023. The Company is continuing to assess 
the potential impact of these changes.

The conflict in Ukraine could adversely affect our future results of operations.

The  current  conflict  in  Ukraine  has  led  to,  among  other  things,  hardship  and  the  imposition  of  international 
economic sanctions aimed at the region. While the situation is subject to change, there remains the possibility of additional 
and  harsher  sanctions  if  the  conflict  intensifies.  If  that  were  to  happen,  our  operations  in  the  region  may  be  severely 
curtailed or eliminated, which could adversely affect our results of operations. In addition, if the current unrest broadens or 
further escalates, our operations may be severely curtailed, which could adversely affect our results of operations.

We may lose business as a result of changes in the regulatory environment.

Various  regulatory  bodies  throughout  the  world  may  enact  legislation,  rules  and  guidance  which  could  introduce 
changes  to  the  regulatory  environment  for  drug  development  and  research.  The  adoption  and  implementation  of  such 
legislation, rules and guidance is difficult to predict and therefore could have a material adverse effect on our business.

Failure  to  comply  with  the  regulations  and  requirements  of  the  U.S.  Food  and  Drug  Administration  and  other 
regulatory authorities could result in substantial penalties and/or loss of business.

The  U.S.  Food  and  Drug Administration,  ("FDA"),  and  other  regulatory  and  government  authorities  and  agencies 
inspect  and  audit  us  from  time  to  time  to  ensure  that  we  comply  with  their  regulations  and  guidelines,  including 
environmental,  health  and  safety  matters,  and  other  requirements  imposed  in  connection  with  the  performance  of 
government contracts.  We must comply with the applicable regulatory requirements governing the conduct of clinical trials 
and contracting with the government in all countries in which we operate. 

If we fail to comply with any of these requirements we could suffer some or all of: 

•
•
•
•
•
•
•
•

termination of or delay in any research;
disqualification of data;
denial of the right to conduct business;
criminal penalties;
financial penalties;
other enforcement actions including debarment from government contracts;
loss of clients and/or business; and
litigation from clients and/or patients and/or regulatory authorities and/or other affected third parties, and 
resulting material penalties, damages and costs.

We are subject to political, regulatory, operational and legal risks associated with our international operations. 

We are one of a small group of organisations with the capability and expertise to conduct clinical trials on a global 
basis. We believe that this capability to provide our services globally in most major and developing pharmaceutical markets 
enhances  our  ability  to  compete  for  new  business  from  large  multinational  pharmaceutical,  biotechnology  and  medical 
device companies. We have expanded geographically in the past and intend to continue expanding in regions that have the 
potential to increase our client base or increase our investigator and patient populations. We expect that revenues earned in 
emerging  markets  will  continue  to  account  for  an  increasing  portion  of  our  total  revenues.  However,  emerging  market 
operations may present several risks, including civil disturbances, health concerns, cultural differences such as employment, 
regulatory  and  business  practices,  compliance  with  economic  sanctions,  laws  and  regulations,  volatility  in  gross  domestic 
product,  economic  and  governmental  instability,  the  potential  for  nationalization  of  private  assets  and  the  imposition  of 
exchange controls. In addition, operating globally means the Company faces the challenges associated with coordinating its 
services across different countries, time zones and cultures.

Appendix A: Risk Factors (continued)

Changes in the political and regulatory environment in the international markets in which we operate such as price 
or  exchange  controls  could  impact  our  revenue  and  profitability  and  could  lead  to  penalties,  sanctions  and  reputational 
damages if we are not compliant with those regulations. Political uncertainty and a lack of institutional continuity in some of 
the  emerging,  developing  or  other  countries  in  which  we  operate  could  affect  the  orderly  operation  of  markets  in  these 
economies.  In  addition,  in  countries  with  a  large  and  complicated  structure  of  government  and  administration,  national, 
regional, local and other governmental bodies may issue inconsistent decisions and opinions that could increase our cost of 
regulatory compliance and/or have a material adverse effect on our business. The ongoing conflict in Ukraine has resulted in 
an increasingly complex economic sanctions and export controls environment applicable to our business operations in the 
region  (including  Russia  and  Belarus)  as  a  result  of  additional  trade  compliance  measures  enacted  by  the  United  States, 
United Kingdom and European Union member states.  These economic sanctions and export controls restrict our ability to 
do business with sanctioned entities, require additional compliance resources, and could have a material adverse effect on 
the results of our operations.

Uncertainty of the legal environment in some emerging countries could also limit our ability to enforce our rights. In 
certain  emerging  and  developing  countries  we  enjoy  less  comprehensive  protection  for  some  of  our  rights,  including 
intellectual property rights, which could undermine our competitive position. Proceedings to enforce our future patent rights, 
if any, in foreign jurisdictions could result in substantial cost and divert our efforts and attention from other aspects of our 
business. 

If any of the above risks or similar risks associated with our international operations were to materialize, our results 

of operations and financial condition could be materially adversely affected.

We operate in many different jurisdictions and we could be adversely affected by violations of anti-corruption laws, 
including the United States Foreign Corrupt Practices Act of 1977 ("FCPA"), UK Bribery Act of 2010 ("Bribery Act") 
and similar anti-corruption laws in other jurisdictions as well as laws and regulations relating to trade compliance 
and economic sanctions.

The FCPA, UK Bribery Act of 2010 and similar anti-corruption laws in other jurisdictions prohibit us and our officers, 
directors, employees and third parties acting on our behalf, including agents, from corruptly offering, promising, authorizing, 
or providing anything of value to a "foreign official" for the purposes of influencing official decisions or obtaining or retaining 
business or otherwise obtaining favorable treatment. In addition, the FCPA imposes certain books, records and accounting 
control  obligations  on  public  companies  and  other  issuers.  The  UK  Bribery  Act  also  prohibits  "commercial"  bribery  and 
accepting bribes. 

Our  global  business  operations  also  must  be  conducted  in  compliance  with  applicable  export  controls  and 
economic sanctions laws and regulations, including those administered by the U.S. Department of the Treasury’s (the “U.S. 
Treasury”) Office of Foreign Assets Control, the U.S. Department of State, the U.S. Department of Commerce, the United 
Nations Security Council, the European Union, His Majesty’s Treasury and other relevant trade compliance authorities.

Our  internal  policies  mandate  compliance  with  these  anti-corruption  and  trade  compliance  laws  and  regulations. 
We also operate in many jurisdictions in which bribery or corruption can be common and compliance with anti-bribery laws 
may conflict with local customs and practices. Despite our training and compliance program safeguards, we cannot assure 
that our internal control policies, procedures and safeguards will protect us from acts in violation of anti-corruption and trade 
compliance  laws  and  regulations  committed  by  employees  or  other  third  parties  associated  with  us  and  our  continued 
expansion, including in developing countries, could increase such risk in the future. Violations of anti-corruption, economic 
sanctions  and  trade  control  laws  and  regulations,  or  even  allegations  of  such  violations,  could  disrupt  our  business  and 
result in a material adverse effect on our financial condition, results of operations, cash flows and reputation. For example, 
violations  of  anti-corruption  and  trade  compliance  laws  can  result  in  restatements  of,  or  irregularities  in,  our  financial 
statements,  disgorgement  of  profits,  related  stockholder  lawsuits  as  well  as  severe  criminal  or  civil  sanctions.  In  some 
cases, companies that violate anti-corruption and trade compliance laws might be debarred by the U.S. government and/or 
lose their U.S. export privileges. In addition, the U.S. government or other governments may seek to hold us liable based on 
successor liability for violations of anti-corruption and trade compliance laws committed by companies that we acquire or in 
which  we  invest.  Changes  in  anti-corruption  and  trade  compliance  laws  or  enforcement  priorities  could  also  result  in 
increased  compliance  requirements  and  related  costs  which  could  materially  adversely  affect  our  business,  financial 
condition, results of operations and cash flows. The recent increase in economic sanctions and trade controls, particularly 
relating  to  our  ongoing  operations  in  Russia,  Ukraine  and  Belarus,  has  increased  the  amount  of  resources  necessary  to 
ensure compliance in this area.

167

Appendix A: Risk Factors (continued)

Current  and  proposed  laws  and  regulations  regarding  the  protection  of  personal  data  could  result  in  increased 
risks of liability or increased costs to us or could limit our service offerings.

ICON has a strong privacy posture, driven by the implementation of a core privacy governance strategy and the 
adoption  of  policies  and  procedures  designed  to  help  ensure  that  ICON,  including  our  employees  and  contractors,  can 
comply with applicable data protection laws (including, but not limited to, the General Data Protection Regulation (“GDPR”) 
(EU)  2016/679).  Notwithstanding  these  measures,  failure  to  comply  with  applicable  data  protection  laws  may  occur  and 
could result in increased risk of liability or increased costs to us or could limit our service offerings. 

Administrative fines. The GDPR introduced a new regime of administrative fines for data protection infringements 
and provided for a tiered penalty structure based on the nature of the infringement. The EU supervisory authorities for the 
GDPR can directly impose fines on organisations found to be in breach of the GDPR. Lower tier administrative fines allow 
for fines of up to 2% of worldwide turnover of the group in the preceding financial year. Higher tier administrative fines allow 
for fines of up to 4% of worldwide turnover of the group in the preceding financial year. Higher tier administrative fines are 
more  likely  to  be  levied  for  major  infringements  of  the  GDPR  and  core  data  protection  principles  (e.g.  transparency,  data 
retention, accountability). 

Penalties.  The  GDPR  also  permits  Member  States  to  implement  rules  on  other  penalties  applicable  to 
infringements  of  the  GDPR,  in  particular,  for  infringements  which  are  not  subject  to  administrative  fines  under  the  GDPR 
itself. Therefore, Member States may legislate for further fines or penalties that may be criminal in nature. 

Any  fines  levied  under  the  GDPR  must  be  effective,  proportionate,  and  dissuasive.  Supervisory  authorities  have 
been strengthening enforcement activities across the EU in recent years in respect of breaches of GDPR. The risk of fines 
and penalties under the GDPR carries increased risk of liability to ICON and can result in increased costs and disruption to 
the delivery of our services. 

Right to compensation of data subjects. In addition to the risk of administrative and criminal penalties, the GDPR 
also provides that any person who has suffered material or non-material damage as a result of an infringement of the GDPR 
shall have the right to receive compensation for the damage suffered, from the controller or processor responsible for the 
infringement. The level of award of damages is set by the competent court in the applicable EU Member State. This carries 
increased risk of liability for ICON. 

Corrective Powers of the supervisory authorities.  Each supervisory authority across the Member States of the EU 
also  has  corrective  powers.  Supervisory  authorities  have  the  power  to  order  ICON  to  bring  processing  operations  into 
compliance with the provisions of the GDPR in a specified manner within a specified time period, or to impose a temporary 
or  definitive  limitation  including  a  ban  on  processing,  and  to  order  the  suspension  of  data  flows  to  a  recipient  in  a  third 
country or to an international organisation. Supervisory authorities also have powers to conduct audits and investigations of 
ICON and instruct ICON to take certain actions. The exercise of these powers by supervisory authorities has the potential to 
increase costs for ICON and cause disruption to the business and delivery of our services. 

From  a  US  perspective,  the  confidentiality,  collection,  use  and  disclosure  of  personal  data,  including  clinical  trial 
patient-specific  information,  is  subject  to  governmental  regulation  generally  in  the  country  that  the  personal  data  was 
collected or used. For example, United States federal regulations under the Health Insurance Portability and Accountability 
Act of 1996, or ("HIPAA"), and as amended in 2014 by the Health Information Technology for Economic and Clinical Health 
(“HITECH”)  Act,  require  individuals’  written  authorization,  in  addition  to  any  required  informed  consent,  before  Protected 
Health Information may be used for research. HIPAA specifies standards for de-identifications and for limited data sets. We 
are  both  directly  and  indirectly  affected  by  the  privacy  provisions  surrounding  individual  authorizations  because  many 
investigators and organisations with whom we are involved in clinical trials and in our services are directly subject to them 
as a HIPAA “covered entity” and because we obtain identifiable health information from third parties that are subject to such 
regulations. As there are some instances where we are a HIPAA “business associate” of a “covered entity”, we can also be 
directly  liable  to  the  covered  entity  contractually  for  mishandling  protected  health  information  and,  under  HIPAA’s 
enforcement scheme, we can be subject to up to $1.9 million per year in civil money penalties for identical HIPAA violations. 
The  per  violation  penalties  and  calendar  year  cap  on  penalties  are  adjusted  annually  for  inflation  under  the  Federal  Civil 
Penalties Inflation Adjustment Act.

The foundational principles of the GDPR have helped shape the development of many other privacy laws globally. 
Internationally, data protection laws continue to be introduced at a rapid rate, with greater protections afforded to personal 
data than ever before, and greater risk of liability to organisations processing that personal data. As a global organisation, 
ICON must ensure that our privacy posture continues to adapt to these new laws and regulations.

168

Appendix A: Risk Factors (continued)

Additional  legislation  or  regulation  of  this  type  might,  among  other  things,  require  us  to  implement  new  security 
measures  and  processes  which  may  require  substantial  expenditures  or  limit  our  ability  to  offer  some  of  our  services. 
Additionally, if we violate applicable laws, regulations or duties relating to the use, processing or security of personal data, 
we could be subject to civil liability or criminal prosecution, be forced to alter our business practices or suffer reputational 
harm. 

Our  employees  may  engage  in  misconduct  or  other  improper  activities,  including  noncompliance  with  regulatory 
standards and requirements, which could have a material adverse effect on our business. 

We  are  exposed  to  the  risk  of  employee  fraud  or  other  misconduct.  Misconduct  by  employees  could  include 
intentional failures to comply with governmental regulations, comply with federal and state healthcare fraud and abuse laws 
and regulations, report financial information or data accurately or disclose unauthorized activities to us. In particular, sales, 
marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to 
prevent  fraud,  kickbacks,  self-dealing  and  other  abusive  practices.  These  laws  and  regulations  may  restrict  or  prohibit  a 
wide  range  of  pricing,  discounting,  marketing  and  promotion,  sales  commission,  customer  incentive  programs  and  other 
business arrangements. Employee misconduct could also involve the improper use of information obtained in the course of 
clinical studies or data or documentation fraud or manipulation, which could result in regulatory sanctions and serious harm 
to our reputation. It is not always possible to identify and deter employee misconduct, and the precautions we take to detect 
and prevent misconduct may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from 
governmental  investigations  or  other  actions  or  lawsuits  stemming  from  a  failure  to  be  in  compliance  with  such  laws  or 
regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our 
rights, those actions could have a significant impact on our business and results of operations, including the imposition of 
significant fines or other sanctions.

The  failure  to  comply  with  our  government  contracts  or  applicable  laws  and  regulations  could  result  in,  among 
other  things,  fines  or  other  liabilities,  and  changes  in  procurement  regulations  could  adversely  impact  our 
business, results of operations or cash flows.

Revenues  from  our  government  customers  are  derived  from  sales  to  federal,  state  and  local  governmental 
departments  and  agencies  through  various  contracts.  Sales  to  public  segment  customers  are  highly  regulated. 
Noncompliance  with  contract  provisions,  government  procurement  regulations  or  other  applicable  laws  or  regulations 
(including  but  not  limited  to  the  False  Claims  Act)  could  result  in  civil,  criminal  and  administrative  liability,  including 
substantial  monetary  fines  or  damages,  termination  of  government  contracts  or  other  public  segment  customer  contracts, 
and  suspension,  debarment  or  ineligibility  from  doing  business  with  the  government  and  other  customers  in  the  public 
segment. In addition, generally contracts in the public segment are terminable at any time for convenience of the contracting 
agency  or  upon  default.  The  effect  of  any  of  these  possible  actions  by  any  governmental  department  or  agency  could 
adversely affect our business, results of operations or cash flows. In addition, the adoption of new or modified procurement 
regulations and other requirements may increase our compliance costs and reduce our gross margins, which could have a 
negative effect on our business, results of operations or cash flows.

Liability  claims  brought  against  us  could  result  in  payment  of  substantial  damages,  costs  and  liabilities  and 
decrease our profitability.

We  may  face  legal  claims  involving  stockholders,  consumers,  clinical  trial  subjects,  competitors,  regulators  and 
other  parties.  See  'Legal  Proceedings'  in  Part  A,  Item  8  of  this  Form  20-F.  Litigation  and  other  legal  proceedings  are 
inherently  uncertain,  and  adverse  rulings  could  occur,  including  monetary  damages,  or  an  injunction  stopping  us  from 
engaging in business practices, or requiring other remedies, including, but not limited to, compulsory licensing of patents. In 
addition,  the  combined  Company  may  be  exposed  to  increased  litigation  from  stockholders,  customers,  suppliers, 
consumers and other third parties due to the combination of ICON’s business and PRA’s business following the Merger.

Customer Claims

If we breach the terms of an agreement with a customer (for example if we fail to comply with the agreement, all 
applicable regulations or Good Clinical Practice) this could result in claims against us for substantial damages which could 
have  a  material  adverse  effect  on  our  business.  As  we  provide  staff  to  deliver  our  services,  there  is  a  risk  that  our 
management,  quality  and  control  structures  fail  to  quickly  detect  a  failure  by  one  or  more  employees  or  contractors  to 
comply  with  all  applicable  regulations  and  Good  Clinical  Practice  and  our  internal  requirements  and  standard  operating 
procedures thereby exposing us to the risk of claims by customers.

Claims relating to Investigators

We  contract  with  physicians  who  serve  as  investigators  in  conducting  clinical  trials  to  test  new  drugs  on  their 
patients.  These  patients  will  generally  have  underlying  health  conditions  and  this  testing  creates  the  risk  of  liability  for 

169

 
 
 
Appendix A: Risk Factors (continued)

personal injury to the patient or the risk of a serious adverse event occurring. Although investigators are generally required 
by  law  to  maintain  their  own  liability  insurance,  we  could  be  named  in  lawsuits  and  incur  expenses  arising  from  any 
professional malpractice or other actions brought against the investigators with whom we contract.

Indemnification from Customers

Indemnifications provided by our customers against the risk of liability for personal injury to or death of the patients 
arising from a study drug vary from customer to customer and from trial to trial and may not be sufficient in scope or amount, 
or our customer may not have the financial ability to fulfill their indemnification obligations. Furthermore, we would be liable 
for  our  own  negligence  and  negligence  of  our  employees  which  could  lead  to  litigation  from  customers  or  action  or 
enforcement by regulatory authorities.

Insurance

We  maintain  what  we  believe  is  an  appropriate  level  of  worldwide  Professional  Liability/Error  and  Omissions 
Insurance. In the future we may be unable to maintain or continue our current insurance coverage on the same or similar 
terms. If we are liable for a claim or settlement that is beyond the level of insurance coverage, we may be responsible for 
paying all or part of any award or settlement amount. Also, the insurance policies contain exclusions which mean that the 
policy will not respond or provide cover in certain circumstances.

Claims to Date

To  date,  we  have  not  been  subject  to  any  liability  claims  that  are  expected  to  have  a  material  effect  on  our 
business;  however,  there  can  be  no  assurance  that  we  will  not  become  subject  to  such  claims  in  the  future  or  that  such 
claims will not have a material effect on our business.

Environmental, social and governance matters may impact our business and reputation.

Increasingly,  in  addition  to  the  importance  of  their  financial  performance,  companies  are  being  judged  by  their 
performance on a variety of environmental, social and governance ('ESG') matters, which are considered to contribute to the 
long-term sustainability of companies’ performance. A variety of organisations measure the performance of companies on 
such ESG topics, and the results of these assessments are widely publicized. Customers may have specific ESG related 
requirements  or  targets  and  if  we  fail  to  meet  these  targets  we  may  lose  business.  In  addition,  investment  in  funds  that 
specialize  in  companies  that  perform  well  in  such  assessments  are  increasingly  popular,  and  major  institutional  investors 
have publicly emphasized the importance of such ESG measures to their investment decisions. Topics taken into account in 
such assessments include, among others, the Company’s efforts and impacts on climate change and human rights, ethics 
and compliance with law, and the role of the Company’s board of directors in supervising various sustainability issues. We 
actively manage a broad range of such ESG matters, taking into consideration their expected impact on the sustainability of 
our  business  over  time,  and  the  potential  impact  of  our  business  on  society  and  the  environment.  However,  in  light  of 
investors’ increased focus on ESG matters, there can be no certainty that we will manage such issues successfully, or that 
we will successfully meet society’s perceived expectations as to our proper role. Any failure or perceived failure by us in this 
regard  could  have  a  material  adverse  effect  on  our  reputation  and  on  our  business,  share  price,  financial  condition,  or 
results of operations, including the sustainability of our business over time.

Risk Related to Our Common Stock

Volatility in the market price of our common stock could lead to losses by investors.

The market price of our common stock has experienced volatility in the past and may experience volatility in the future which 
could  lead  to  losses  for  investors.  Factors  impacting  volatility  in  the  market  price  of  our  common  stock  include,  amongst 
others:

•
•
•
•
•
•
▪

•

•

general market and economic conditions;
our results of operations; 
issuance of new or changed securities analysts’ reports or recommendations;
developments impacting the industry or our competitors;
declines in the market prices of stocks generally;
strategic actions by us or our competitors; 
announcements  by  us  or  our  competitors  of  significant  contracts,  new  products,  acquisitions,  joint  marketing 
relationships, joint ventures, other strategic relationships or capital commitments;
the public's reaction to press releases, other public announcements by us or third parties, including our filings with 
the SEC;
guidance, if any, that we provide to the public, any changes in this guidance or failure to meet this guidance;

170

 
 
 
Appendix A: Risk Factors (continued)

•
•
•
•
•
•
•
•
•
•

changes in the credit rating of our debt;
sale, or anticipated sale, of large blocks of our stock;
additions or departures of key personnel;
regulatory or political developments;
our performance on ESG matters
litigation and governmental investigations;
changing economic conditions;
exchange rate fluctuations; 
changes in accounting principles; and
other events or factors, including those resulting from natural disasters, war, acts of terrorism or responses to those 
events.   

In  addition,  stock  markets  have  from  time  to  time  experienced  significant  price  and  volume  fluctuations  unrelated  to  the 
operating performance of particular companies. Future fluctuations in stock markets may lead to volatility in the market price 
of our common stock which could lead to losses by investors.

Investment returns may be reduced if we lose our foreign private issuer status. 

We are a “foreign private issuer,” as such term is defined in Rule 405 under the U.S. Securities Act 1933, and, therefore, we 
are not required to file quarterly reports on Form 10-Q or current reports on Form 8-K with the SEC. In addition, the proxy 
rules  and  Section  16  reporting  and  short-swing  profit  recapture  rules  are  not  applicable  to  us.  If  we  lose  our  status  as  a 
foreign private issuer by our election or otherwise and we become subject to the full reporting regime of the United States 
securities laws, we will be subject to additional reporting obligations and proxy solicitation obligations under the Exchange 
Act and our officers, directors and 10% shareholders would become subject to the short-swing profit rules. The imposition of 
these reporting rules would increase our costs and the obligations of those affected by the short-swing rules.

We do not expect to pay any cash dividends for the foreseeable future.

We currently do not expect to declare dividends on our common stock and have not done so in the past. We continue to 
anticipate that our earnings will be used to provide working capital, to support operations, to make debt repayments and to 
finance the growth and development of our business. They may also be used to continue our share repurchase program. 
Any  determination  to  declare  or  pay  dividends  in  the  future  will  be  at  the  discretion  of  our  board  of  directors,  subject  to 
relevant  laws  and  dependent  on  a  number  of  factors,  including  our  earnings,  capital  requirements  and  overall  financial 
condition. Therefore, the only opportunity for stockholders to achieve a return on their investment may be if the market price 
of  our  common  stock  appreciates  and  shares  are  sold  at  a  profit.  The  market  price  for  our  common  stock  may  not 
appreciate and may fall below the price stockholders paid for such common stock. 

A future transfer of ICON ordinary shares, other than one effected by means of the transfer of book entry interests 
in the Depositary Trust Company ("DTC"), may be subject to Irish stamp duty.

Transfers  of  ICON  ordinary  shares  effected  by  means  of  the  transfer  of  book  entry  interests  in  the  Depositary  Trust 
Company  ("DTC")  should  not  be  subject  to  Irish  stamp  duty  where  ICON  ordinary  shares  are  traded  through  DTC,  either 
directly or through brokers that hold such shares on behalf of customers through DTC. However, if ICON ordinary shares 
are held as of record rather than beneficially through DTC, any transfer of ICON ordinary shares could be subject to Irish 
stamp duty (currently at the rate of 1% of the higher of the price paid or the market value of the shares acquired). Payment 
of Irish stamp duty is generally a legal obligation of the transferee. The potential for Irish stamp duty to arise could adversely 
affect the price of ICON ordinary shares.

Forward-looking statements

To  the  extent  any  statements  made  in  this  annual  report  deal  with  information  that  is  not  historical,  these  statements  are 
necessarily  forward-looking.  Because  forward-looking  statements  relate  to  the  future,  they  are  subject  to  inherent 
uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of the Group’s 
control. Any forward-looking statement made by the Group is based only on information currently available as at the time of 
publication of this report. Forward-looking statements are subject to the occurrence of many events outside of the Group’s 
control and are subject to various risk factors that would cause our results to differ materially from those expressed in any 
forward-looking  statement.  These  risk  factors  described  in  Appendix  A  include,  without  limitation,  the  inherent  risk  of 
dependence on pharmaceutical and biotechnology industries and certain clients, termination or delay of large contracts, risk 
of cost overruns, the risk of clinical outcomes, regulatory risks and market competition.
