You should read the following discussion and analysis of our financial condition
and results of operations in conjunction with our consolidated condensed
financial statements and the notes thereto included elsewhere in this Quarterly
Report on Form 10-Q, with our audited consolidated financial statements and the
notes thereto included in our Annual Report on Form 10-K for the fiscal year
ended December 31, 2020, as amended, or the Annual Report, and with the
information under the heading "Management's Discussion and Analysis of Financial
Condition and Results of Operations" in our Annual Report.

We use the terms "we," "us," "our," or the "Company" in this report to refer to PRA Health Sciences, Inc. and its subsidiaries.

Overview



We are one of the world's leading global contract research organizations, or
CROs, by revenue, providing outsourced clinical development services to the
biotechnology and pharmaceutical industries. We believe we are one of a select
group of CROs with the expertise and capability to conduct clinical trials
across major therapeutic areas on a global basis. Our therapeutic expertise
includes areas that are among the largest in pharmaceutical development, and we
focus in particular on oncology, immunology, central nervous system
inflammation, respiratory, cardiometabolic, and infectious diseases. We believe
that we further differentiate ourselves from our competitors through our
investments in medical informatics and clinical technologies designed to enhance
efficiencies, improve study predictability, and provide better transparency for
our clients throughout their clinical development processes. Our Data Solutions
segment allows us to better serve our clients across their entire product
lifecycle by (i) improving clinical trial design, recruitment, and execution;
(ii) creating real-world data solutions based on the use of medicines by actual
patients in normal situations; and (iii) increasing the efficiency of healthcare
companies' commercial organizations through enhanced analytics and outsourcing
services.

On February 24, 2021, we entered into the a definitive merger agreement with
ICON plc (ICON), ICON US Holdings Inc. (US Holdco) and Indigo Merger Sub, Inc.
(Merger Sub). Under the terms of the merger agreement, Merger Sub will merge
with and into PRA, with PRA surviving as a wholly owned subsidiary of ICON and
US HoldCo. Upon successful completion of the merger, our stockholders will
receive $80.00 per share in cash and 0.4125 ICON ordinary shares for each share
of our common stock.

The merger, which is currently expected to close in July 2021, is subject to the
satisfaction or waiver of certain customary closing conditions, including, among
others, receipt of the required vote of our stockholders and the required vote
of ICON shareholders, and obtaining all required approvals under antitrust and
foreign direct investment laws of certain jurisdictions. The merger agreement
contains certain termination rights for both us and ICON. If the merger
agreement is terminated under certain specified circumstances, we will be
required to pay ICON and ICON US Holdings Inc., a Delaware corporation and
wholly owned subsidiary of ICON ("US Holdco"), a termination fee of $277.0
million (including in connection with our entry into an agreement with respect
to a superior proposal, as defined in the merger agreement, if certain
conditions are met).

How We Assess the Performance of Our Business



The Company is managed through two reportable segments: (i) the Clinical
Research segment and (ii) the Data Solutions segment. Our chief operating
decision-maker uses segment profit as the primary measure of each segment's
operating results in order to allocate resources and in assessing the Company's
performance. In addition to our financial measures in conformity with U.S.
generally accepted accounting principles, or GAAP, including revenue, costs, and
expenses and other measures discussed below, we review various financial and
operational metrics. For our Clinical Research segment, we review new business
awards, cancellations, and backlog.

Our gross new business awards for our Clinical Research segment for the three
months ended March 31, 2021 and 2020 were $908.6 million and $657.9 million,
respectively. New business awards arise when a client selects us to execute its
trial and is documented by written or electronic correspondence, or for our
Strategic Solutions offering when the amount of revenue expected to be
recognized is measurable. The number of new business awards can vary
significantly from year to year, and awards can have terms ranging from several
months to several years. For our Strategic Solutions offering, the value of a
new business award is the anticipated revenue to be recognized in the
corresponding quarter of the next fiscal year. For the remainder of our Clinical
Research segment, the value of a new award is the anticipated revenue over the
life of the contract, which does not include reimbursable expenses.

                                       21
--------------------------------------------------------------------------------
  Table of Contents
In the normal course of business, we experience contract cancellations, which
are reflected as cancellations when the client provides us with written or
electronic correspondence that the work should cease. During the three months
ended March 31, 2021 and 2020, we had $111.4 million and $53.2 million,
respectively, of cancellations for which we received correspondence from the
client for our Clinical Research segment. The number of cancellations can vary
significantly from period to period. The value of the cancellation is the
remaining amount of unrecognized service revenue, less the estimated effort to
transition the work back to the client.

Our backlog consists of anticipated revenue from new business awards that either
have not started or are in process but have not been completed for our Clinical
Research segment. Backlog varies from period to period depending upon new
business awards and contract modifications, cancellations, and the amount of
revenue recognized under existing contracts. Our backlog at March 31, 2021 and
2020 was $5.5 billion and $4.7 billion, respectively.

Sources of Revenue



Total revenues are comprised of revenues from the provision of our services and
revenues from reimbursed expenses and reimbursable investigator grants that are
incurred while providing our services. We do not have any material product
revenues.

Costs and Expenses



Our costs and expenses are comprised primarily of our direct costs, selling,
general and administrative costs, depreciation and amortization expense, and
income taxes.

Direct Costs (Exclusive of Depreciation and Amortization)



For our Clinical Research segment, direct costs consist primarily of
labor-related charges. They include elements such as salaries, benefits, and
incentive compensation for our employees. In addition, we utilize staffing
agencies to procure primarily part time individuals to perform work on our
contracts. Labor-related charges as a percentage of the Clinical Research
segment's total direct costs were 96.9% for both the three months ended March
31, 2021 and 2020. The cost of labor procured through staffing agencies is
included in these percentages and represents 3.8% and 2.9% of the Clinical
Research segment's total direct costs for the three months ended March 31, 2021
and 2020, respectively. Our remaining direct costs are items such as travel,
meals, postage and freight, patient costs, medical waste, and supplies. The
total of all these items as a percentage of the Clinical Research segment's
total direct costs were 3.1% for both the three months ended March 31, 2021 and
2020.

Historically, direct costs have increased with an increase in revenues. The
future relationship between direct costs and revenues may vary from historical
relationships. Several factors will cause direct costs to decrease as a
percentage of revenues. Deployment of our billable staff in an optimally
efficient manner has the most impact on our ratio of direct cost to revenue. The
most effective deployment of our staff is when they are fully engaged in
billable work and are accomplishing contract related activities at a rate that
meets or exceeds budgeted targets. We also seek to optimize our efficiency by
performing work using the employee with the lowest cost. Generally, the
following factors may cause direct costs to increase as a percentage of
revenues: our staff are not fully deployed, as is the case when there are
unforeseen cancellations or delays, or when our staff are accomplishing tasks at
levels of effort that exceed budget, such as rework, as well as pricing pressure
from increased competition.

For our Data Solutions segment, direct costs consist primarily of data costs.
Data costs as a percentage of the Data Solutions segment's total direct costs
were 75.5% and 74.3% for the three months ended March 31, 2021 and 2020,
respectively. Labor-related charges, such as salaries, benefits, and incentive
compensation for our employees, were 19.9% and 20.2% of the Data Solutions
segment's total direct costs for the three months ended March 31, 2021 and 2020,
respectively. Our remaining direct costs are items such as travel, meals, and
supplies, and were 4.6% and 5.5% of the Data Solutions segment's total direct
costs for the three months ended March 31, 2021 and 2020, respectively.

Reimbursable Expenses



As is customary in our industry, we also routinely enter into separate
agreements on behalf of our clients with independent physician investigators in
connection with clinical trials. We also receive funds from our clients for
investigator fees. We are not obligated either to perform the service or to pay
the investigator in the event of default by the client. In addition, we do not
pay the independent physician investigator until funds are received from the
client. We include these investigator fees, as well as our out-of-pocket costs
that are reimbursable by our customers, as reimbursable expenses in our
consolidated condensed statements of operations.
                                       22

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

Table of Contents

Reimbursable expenses are not included in our backlog because they are pass-through costs to our clients.



We believe that the fluctuations in reimbursable expenses are not meaningful to
the final economic performance as measured on a net basis given that such costs
are passed through to the client. The reimbursable expenses are included in our
measure of progress for our long-term contracts.

Selling, General and Administrative Expenses



Selling, general and administrative expenses consist of administration payroll
and benefits, marketing expenditures, and overhead costs such as information
technology and facilities costs. These expenses also include central overhead
costs that are not directly attributable to our operating business and include
certain costs related to insurance, professional fees, and property.

Transaction-related Costs

Transaction-related costs include costs associated acquisition related earn-out liabilities or adjustments to the initial fair value estimates and expenses associated with our acquisitions, including the proposed merger with ICON.

Depreciation and Amortization Expense



Depreciation expense represents the depreciation charged on our fixed assets.
The charge is recorded on a straight-line method, based on estimated useful
lives of three to seven years for computer hardware and software and five to
seven years for furniture and equipment. Leasehold improvements are depreciated
over the lesser of the life of the lease term or the useful life of the
improvements.

Amortization expense consists of amortization recorded on acquisition-related
intangible assets. Customer relationships, backlog, and finite-lived trade names
are amortized on an accelerated basis, which coincides with the period of
economic benefit we expect to receive. All other finite-lived intangibles are
amortized on a straight-line basis. In accordance with GAAP, we do not amortize
goodwill and indefinite-lived intangible assets.

Income Taxes



Because we conduct operations on a global basis, our effective tax rate has
depended and will continue to depend upon the geographic distribution of our
pre-tax earnings among several different taxing jurisdictions. Our effective tax
rate can also vary based on changes in the tax rates of the different
jurisdictions. Our effective tax rate is also impacted by tax credits and the
establishment or release of deferred tax asset valuation allowances and tax
reserves, as well as significant non-deductible items such as portions of
transaction-related costs.

In addition, our effective income tax rate is influenced by U.S. tax law which
has been substantially modified by the U.S. Tax Cuts and Jobs Act of 2017, or
the Act. The following provisions of the Act could have an adverse effect on our
tax rate:
•global intangible low-taxed income, or GILTI;
•limitations on the U.S. deductions for net business interest;
•base erosion anti-abuse provisions, or BEAT; and
•performance-based compensation subject to $1 million limit.

Significant judgment is required related to the application of the Act,
particularly with respect to GILTI and BEAT provisions. If changes occur in the
Company's tax structure, the structure of its customer arrangements, or
interpretations of regulations that clarify these or other provisions of the
Act, these changes could have a material effect on the Company's tax provision.

Foreign subsidiaries are taxed separately in their respective jurisdictions. We
have foreign net operating loss carryforwards in some jurisdictions. The
carryforward periods for these losses vary from four years to an indefinite
carryforward period depending on the jurisdiction. Our ability to offset future
taxable income with the net operating loss carryforwards may be limited in
certain instances, including changes in ownership.

The majority of our foreign operations transact in the Euro, or EUR, or British

rate fluctuations with respect to these currencies. We have translated these
currencies into U.S. dollars using the following exchange rates:

Revenue increased by $150.1 million, or 19.1%, from $783.7 million during the
three months ended March 31, 2020 to $933.8 million during the three months
ended March 31, 2021. Revenue for the three months ended March 31, 2021
benefited from an increase in billable hours, an increase in the effective rate
of hours billed on our studies, and a favorable impact of $12.5 million from
foreign currency exchange rate fluctuations. The growth in revenue and the
increase in billable hours were due largely to the increase in our backlog as we
entered the year, the type of services we are providing on our active studies,
which was driven by the life cycles of projects that were active during the
period, the growth in new business awards as a result of higher demand for our
services across the industries we serve, more effective sales efforts, and the
growth in the overall CRO market. The increase in our effective rate of the
hours billed on our studies is attributable to the contract pricing terms on our
current mix of active studies and the mix of clients and services that we
provide to those clients.

Direct costs, exclusive of depreciation and amortization, increased by $68.1
million, or 16.9%, from $403.9 million during the three months ended March 31,
2020 to $472.0 million during the three months ended March 31, 2021. Salaries
and related benefits in our Clinical Research segment increased $49.3
million due to the hiring of billable staff to support our portfolio of studies.
Data costs in our Data Solutions segment increased $4.1 million due to increased
costs on the renewal of existing contracts and the addition of new sources of
data to expand our data offerings. There was an unfavorable impact of $10.6
million from foreign currency exchange rate fluctuations. Direct costs as a
percentage of revenue were 50.5% and 51.5% during the three months ended March
31, 2021 and 2020, respectively.

Reimbursable expenses increased by $46.5 million from $176.8 million during the
three months ended March 31, 2020 to $223.4 million during the three months
ended March 31, 2021. We believe that the fluctuations in reimbursable expenses
from period to period are not meaningful to our underlying performance over the
full terms of the relevant contracts.

Selling, general and administrative expenses increased by $15.8 million, or
14.8%, from $107.0 million during the three months ended March 31, 2020 to
$122.8 million during the three months ended March 31, 2021. The increase in
selling, general and administrative expenses is primarily related to an increase
in salaries and related benefits, including stock-based compensation expense,
driven by an increase in headcount as we continue to hire staff to support our
growing business. Selling, general and administrative expenses as a percentage
of revenue were 13.1% and 13.6% during the three months ended March 31, 2021 and
2020, respectively.

During the three months ended March 31, 2021, transaction-related costs include
investment banking and legal fees primarily related to the proposed merger with
ICON. During the three months ended March 31, 2020, transaction-related costs
included a $0.6 million adjustment to the fair value of the earn-out liability
associated with the acquisition of Care Innovations, Inc.

Depreciation and amortization expense was $32.6 million and $32.3 million during
the three months ended March 31, 2021 and 2020, respectively. The increase
period over period is due to the amortization of the intangible assets acquired
in connection with the acquisition of Care Innovations as well as an increase in
depreciation expense due to an increase in our depreciable asset base.
Depreciation and amortization expense as a percentage of revenue was 3.5% during
the three months ended March 31, 2021 and 4.1% during the three months ended
March 31, 2020.

Interest expense, net, decreased by $8.3 million, or 61.4%, from $13.5 million
during the three months ended March 31, 2020 to $5.2 million during the three
months ended March 31, 2021. The decrease is primarily due to the expiration of
our floating to fixed interest rate swaps.

Foreign currency gains, net, changed by $4.5 million, from $7.8 million during
the three months ended March 31, 2020 to $12.4 million during the three months
ended March 31, 2021. Foreign currency gains and losses are due to fluctuations
in the U.S. dollar, gains or losses that arise in connection with the
revaluation of short-term inter-company balances between our domestic and
international subsidiaries, and gains or losses from foreign currency
transactions, such as those resulting from the settlement of third-party
accounts receivables and payables denominated in a currency other than the local
currency of the entity making the payment. During the three months ended March
31, 2021, foreign currency gains were primarily due to movement of the U.S.
dollar versus the British pound and Euro.

Provision for income taxes increased by $2.8 million from $16.9 million during
the three months ended March 31, 2020 to $19.7 million during the three months
ended March 31, 2021. Our effective tax rate was 29.3% and 25.7% during the
three months ended March 31, 2020 and 2021, respectively. The comparative
decrease in effective tax rate was primarily driven by the increase of foreign
tax credit resulting from the U.S. inclusion of amounts related to the estimated
tax on GILTI. For the three months ended March 31, 2021, the annual estimated
effective tax rate varied from the U.S. statutory rate of 21% primarily due to
(i) geographic distribution of global pre-tax income, (ii) the U.S. inclusion of
amounts related to the estimated tax on GILTI, and (iii) the impact of state
income taxes.

Revenue increased by $9.6 million, or 16.6%, from $57.6 million during the three
months ended March 31, 2020 to $67.1 million during the three months ended March
31, 2021. The increase in revenue was due to strong contracting activity and
increased volumes across the entirety of Data Solutions' portfolio during the
quarter.

Segment profit increased by $4.9 million, or 40.7%, from $12.1 million during
the three months ended March 31, 2020 to $17.0 million during the three months
ended March 31, 2021 primarily due to an increase in revenue. Segment profit as
a percentage of revenue increased from 21.0% during the three months ended March
31, 2020 to 25.3% for the same period in 2021 primarily due to factors noted
above.

Seasonality

Although our business is not generally seasonal, we typically experience a
slight decrease in our revenue growth rate during the fourth quarter due to
holiday vacations and a similar decrease in new business awards in the first
quarter due to our clients' budgetary cycles and vacations during the year-end
holiday period.

Liquidity and Capital Resources



We assess our liquidity in terms of our ability to generate cash to fund our
operating, investing, and financing activities. Our principal source of
liquidity is operating cash flows. As of March 31, 2021, we had $690.3 million
of cash and cash equivalents of which $116.6 million was held by our foreign
subsidiaries. Additionally, as of March 31, 2021 our Revolver and Accounts
Receivable Financing Agreement provided for $690.2 million of potential
borrowings. Our expected primary cash needs on both a short and long-term basis
are for capital expenditures, expansion of services, geographic expansion, debt
repayments, acquisitions and other strategic transactions, and other general
corporate purposes. We have historically funded our operations and growth,
including acquisitions, with cash flow from operations, borrowings, and
issuances of equity securities. We expect to continue expanding our operations
through internal growth and strategic acquisitions and investments. We expect
these activities will be funded from existing cash, cash flow from operations,
and, if necessary or appropriate, borrowings under our existing or future credit
facilities. Our sources of liquidity could be affected by our dependence on a
small number of industries and clients, compliance with regulations,
international risks (including the ongoing COVID-19 pandemic), and personal
injury, environmental, or other material litigation claims.

Cash Collections



Cash collections from accounts receivable were $1.0 billion during the three
months ended March 31, 2021, including $236.7 million of funds received from
customers to pay independent physician investigators, or investigators, as
compared to $784.2 million during the three months ended March 31, 2020,
including $116.6 million of funds received from customers to pay investigators.
The increase in cash collections during the three months ended March 31, 2021 is
related to our increase in revenue, driven by an increase in new business awards
and an increase in our backlog, as well as improvements in our days sales
outstanding.

Discussion of Cash Flows

                                       26

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

Cash Flow from Operating Activities

During the three months ended March 31, 2021, net cash provided by operations
was $192.2 million compared to $60.6 million for the same period in 2020. Cash
provided by operating activities increased over the prior year primarily due to
improvements in cash flows from working capital changes, driven by an
improvement in our days sales outstanding as compared to the prior year.

Cash Flow from Investing Activities



Net cash used in investing activities was $18.7 million during the three months
ended March 31, 2021 compared to $181.3 million for the same period in 2020. The
decrease in cash outflows is primarily attributable to the acquisition of Care
Innovations in the prior year.

Cash Flow from Financing Activities



Net cash provided by financing activities was $12.0 million during the three
months ended March 31, 2021 compared to $41.2 million for the same period in
2020. The decrease in cash inflows is primarily due to a decrease in our net
borrowings of approximately $45.0 million when compared to the same period in
2020. This is offset by an increase in proceeds from stock option exercises of
approximately $15.4 million when compared to the same period in 2020.

Indebtedness



As of March 31, 2021, we had $1,272.6 million of total indebtedness. We do not
expect to pay dividends in the foreseeable future. Our long-term debt
arrangements contain usual and customary restrictive covenants, and, as of March
31, 2021, we were in compliance with these covenants.
