You should read the following discussion and analysis of our financial condition
and results of operations in conjunction with our condensed consolidated
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, 2022 and with the information under the heading "Management
Discussion and Analysis of Financial Condition and Results of Operations" in our
Annual Report on Form 10-K for the fiscal year ended December 31, 2022. This
item and the related discussion contain forward-looking statements reflecting
current expectations that involve risks and uncertainties. Actual results and
the timing of events may differ materially from those indicated in such
forward-looking statements. Important factors that may cause such differences
include, but are not limited to, those discussed under the "Forward-Looking
Statements" below and "Risk Factors" in "Item 1A Risk Factors" of Part I of our
Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

Forward-Looking Statements



This Quarterly Report on Form 10-Q contains forward-looking statements. We
intend such forward-looking statements to be covered by the safe harbor
provisions for forward-looking statements contained in Section 27A of the
Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934.
All statements other than statements of historical facts contained herein, are
forward looking statements. Forward looking statements include, without
limitation, statements regarding our results of operations; financial position
and performance; liquidity and our ability to fund our business operations and
initiatives; capital expenditure and debt service obligations; business
strategies, plans and goals, including those related to marketing, acquisitions
and expansion of our business; product approvals and plans; industry trends;
general economic conditions, including inflation and other pricing pressures
that could decrease our operating margins; expectations regarding consumer
behaviors and trends; our culture and operating philosophy; human resource
management; arrangements with and delivery of our services to the customers;
conversion of backlog; dividend policy; legal proceedings; and our objectives
for future operations. The words "expect," "anticipate," "intend," "plan,"
"believe," "seek," "see," "will," "would," "target," "likely," and similar
expressions are intended to identify forward-looking statements. Forward-looking
statements are based largely on our current expectations and projections about
future events and financial trends that we believe may affect our financial
condition, results of operations, business strategy, short-term and long-term
business operations and objectives, and financial needs. These forward-looking
statements are subject to inherent uncertainties, risks, changes in
circumstances and other important factors that are difficult to predict.
Moreover, we operate in a very competitive and rapidly changing environment in
which new risks emerge from time to time. It is not possible for our management
to predict all risks, nor can we assess the impact of all important factors on
our business or the extent to which any factor, or combination of such factors,
may cause actual results to differ materially from those contained in any
forward-looking statements we may make. In light of these risks, uncertainties
and assumptions, the forward-looking events and circumstances discussed may not
occur and our financial condition and actual results could differ materially and
adversely from those anticipated or implied in the forward-looking statements.
We caution you therefore against relying on these forward-looking statements.

We qualify all of our forward-looking statements by these cautionary statements.
Except as required by applicable law, we do not plan to publicly update or
revise any forward-looking statements contained herein, whether as a result of
any new information, future events, changed circumstances or otherwise. For a
further discussion of the risks relating to our business, see "Item 1A Risk
Factors" of our Annual Report on Form 10-K for the fiscal year ended
December 31, 2022 and "Part II - Other Information, Item 1A Risk Factors"

How We Generate Revenue



We earn fees through the performance of services detailed in our customer
contracts. Contract scope and pricing is typically based on either a fixed-fee
or unit-of-service model, with consideration of activities performed by third
parties, as well as ancillary costs necessary to deliver on the contract scope
that are reimbursable by our customers. Our contracts can range in duration from
a few months to several years. These contracts are individually priced and
negotiated based on the anticipated project scope, including the complexity of
the project and the performance risks inherent in the project. The majority of
our contracts are structured with an upfront fee that is collected at the time
of contract signing, and the balance of the fee is collected over the duration
of the contract either through an arranged billing schedule or upon completion
of certain performance targets or defined milestones.

Revenue, which is distinct from billing and cash receipt, is recognized based on
the satisfaction of the individual performance obligations identified in each
contract. Substantially all of our customer contracts consist of a single
performance obligation, as the promise to transfer the individual services
defined in the contracts are not separately identifiable from other promises in
the contract, and therefore not distinct. Our performance obligations are
generally satisfied over time and recognized as services are performed. The
progression of our contract performance obligations are measured primarily
utilizing the input method of cost to cost. Cancellation provisions in our
contracts allow our customers to terminate a contract either immediately or
according to advance notice terms specified within the applicable contract,
which is typically 30 days. Contract cancellation may occur for various reasons,
including, but not limited to, adverse patient reactions, lack of efficacy, or
inadequate patient enrollment. Upon cancellation, we are entitled to fees for
services rendered through the date of termination, including payment for
subsequent services necessary to conclude the study or close out the contract.
These fees are typically discussed and agreed upon with the customer and are
realized as revenue when we believe the amount can be estimated reliably and its
realization is probable. Changes in revenue from period to period are driven
primarily by new business volume and task order execution activity, project
cancellations, and the mix of active studies during a given period that can vary
based on therapeutic area and or study life cycle stage.

Costs and Expenses

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



Total Direct Costs

Total direct costs are primarily driven by labor and related employee benefits,
but also include contracted third party service related expenses, fees paid to
site investigators, reimbursed out of pocket expenses, laboratory supplies and
other expenses contributing to service delivery. The other costs of service
delivery can include office rent, utilities, supplies and software licenses
which are allocated between Total direct costs and selling, general and
administrative expenses based on the estimated contribution among service
delivery and support function efforts on a percentage basis. Total direct costs
are expensed as incurred and are not deferred in anticipation of contracts being
awarded or finalization of changes in scope. Total direct costs, as a percentage
of net revenue, can vary from period to period due to project labor
efficiencies, changes in workforce, compensation/bonus programs and service mix.

Selling, General and Administrative

Selling, general and administrative expenses are primarily driven by compensation and related employee benefits, as well as rent, utilities, supplies, software licenses, professional fees (e.g., legal and accounting expenses), bad debt expense, travel, marketing and other operating expenses.

Depreciation



Depreciation is provided on our property and equipment on the straight-line
method at rates adequate to allocate the cost of the applicable assets over
their estimated useful lives, which is three to five years for computer
hardware, software, phone, and medical imaging equipment, five to seven years
for furniture and fixtures and other equipment, and thirty to forty years for
buildings. Leasehold improvements are amortized on a straight-line basis over
the shorter of the estimated useful life of the improvement or the associated
remaining lease term.

Amortization

Amortization relates to finite-lived intangible assets recognized as expense using the straight-line method or using an accelerated method over their estimated useful lives of 15 years.

Income Tax Provision



Income tax provision consists of federal, state and local taxes on income in
multiple jurisdictions. Our income tax is impacted by the pre-tax earnings in
jurisdictions with varying tax rates and any related tax credits that may be
available to us. Our current and future provision for income taxes will vary
from statutory rates due to the impact of valuation allowances in certain
countries, income tax incentives, certain non-deductible expenses, and other
discrete items.

Key Performance Metrics

To evaluate the performance of our business, we utilize a variety of financial and performance metrics. These key measures include new business awards, cancellations and backlog.

New Business Awards, Cancellations and Backlog



New business awards represent the value of anticipated future net revenue that
has been awarded during the period that is recognized in backlog. This value is
recognized upon the signing of a contract or receipt of a written pre-contract
confirmation from a customer that confirms an agreement in principle on budget
and scope. New business awards also include contract amendments, or changes in
scope, where the customer has provided written authorization for changes in
budget and scope or has approved us to perform additional work as of the
measurement date. Awards may not be recognized as backlog after consideration of
a number of factors, including whether (i) the relevant net revenue is expected
only after a pending regulatory hurdle, which might result in cancellation of
the study, (ii) the customer funding needed for commencement of the study is not
believed to have been secured or (iii) study timelines are uncertain or not well
defined. In addition, study amounts that extend beyond a three-year timeline are
not included in backlog. The number and amount of new business awards can vary
significantly from period to period, and an award's contractual duration can
range from several months to several years based on customer and project
specifications.

Cancellations arise in the normal course of business and are reflected when we
receive written confirmation from the customer to cease work on a contractual
agreement. The majority of our customers can terminate our contracts without
cause upon 30 days' notice. Similar to new business awards, the number and
amount of cancellations can vary significantly period over period due to timing
of customer correspondence and study-specific circumstances.

Net new business awards represent gross new business awards received in a period
offset by total cancellations in that period. Net new business awards were
$555.8 million and $423.0 million for the three months ended March 31, 2023 and
2022, respectively.

Backlog represents anticipated future net revenue from net new business awards
that have not commenced or are currently in process but not complete. Reported
backlog will fluctuate based on new business awards, changes in the scope of
existing contracts, cancellations, revenue recognition on existing contracts and
foreign exchange adjustments from non-U.S. dollar denominated backlog. As of
March 31, 2023, our backlog increased by $372.1 million, or 17.8%, to $2,460.1
million compared to $2,088.0 million as of March 31, 2022. Included within
backlog as of March 31, 2023 was approximately $1,320.0 million to $1,340.0
million that we expect to convert to net revenue over the next twelve months,
with the remainder expected to convert to net revenue thereafter.

The effect of foreign currency adjustments on backlog was as follows: favorable
foreign currency adjustments of $3.0 million for the three months ended
March 31, 2023 and favorable foreign currency adjustments of $1.2 million for
the three months ended March 31, 2022.

Backlog and net new business award metrics may not be reliable indicators of our
future period revenue as they are subject to a variety of factors that may cause
material fluctuations from period to period. These factors include, but are not
limited to, changes in the scope of projects, cancellations, and duration and
timing of services provided.

Exchange Rate Fluctuations



The majority of our contracts and operational transactions are U.S. dollar
denominated. The Euro represents the largest foreign currency denomination of
our contractual and operational exposure. As a result, a portion of our revenue
and

Total revenue

Total revenue increased by $103.1 million to $434.1 million for the three months
ended March 31, 2023, from $330.9 million for the three months ended March 31,
2022. The increase for the three months ended March 31, 2023 was primarily
driven by growth within the Oncology, Metabolic, Cardiology and other
therapeutic areas, compared to the same period in the prior year.

Total direct costs



Total direct costs increased by $71.6 million, to $303.9 million for the three
months ended March 31, 2023 from $232.3 million for the three months ended
March 31, 2022. The increase was primarily attributed to higher reimbursed
out-of-pocket expenses and higher personnel costs to support the growth in
service activities. Reimbursed out-of-pocket expenses, which can fluctuate
significantly from period to period based on the timing of program initiation
and closeout, increased $46.0 million for the three months ended March 31, 2023,
compared to the same period in the prior year. The higher personnel costs
portion increased by $19.5 million for the three months ended March 31, 2023,
compared to the same periods in the prior year.

Selling, general and administrative



Selling, general and administrative expenses increased by $8.7 million, to $38.0
million for the three months ended March 31, 2023 from $29.4 million for the
three months ended March 31, 2022. The increase was primarily attributed to
higher personnel costs to support the growth in service activities. The higher
personnel costs portion increased by $4.9 million for the three months ended
March 31, 2023, compared to the same periods in the prior year.

Depreciation and Amortization



Depreciation and amortization expense of $6.0 million for the three months ended
March 31, 2023 remained relatively consistent with $5.1 million for the three
months ended March 31, 2022.

Miscellaneous income, net

Miscellaneous income, net decreased by $0.4 million to $0.7 million for the
three months ended March 31, 2023 from $1.1 million for the three months ended
March 31, 2022. These changes were mainly attributable to foreign exchange gains
and losses that arise in connection with the revaluation of short-term
intercompany balances between our domestic and international subsidiaries and
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.

Income tax provision



Income tax provision increased by $9.1 million, to $13.1 million for the three
months ended March 31, 2023 from $4.0 million for the three months ended
March 31, 2022. The overall effective tax rate for the three months ended
March 31, 2023 was 15.3%, compared to an overall effective tax rate of 6.1% for
the three months ended March 31, 2022. The increase in the income tax provision
and overall effective tax rate was primarily attributable to the increase in
pre-tax book income and a decrease in excess tax benefits recognized from share
based compensation and benefits from uncertain tax positions compared to the
same periods in the prior year.

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 sources of
liquidity are operating cash flows and from borrowings under our unsecured
credit facility consisting of up to a $150.0 million revolving line of credit
which we entered into on September 30, 2019 (the "Credit Facility"), and has
subsequently been amended. As of March 31, 2023, we had cash and cash
equivalents of $46.9 million which increased from $28.3 million as of
December 31, 2022. Approximately $15.6 million of cash and cash equivalents,
none of which was restricted, was held by our foreign subsidiaries as of
March 31, 2023.

As of March 31, 2023, we had $34.8 million available for borrowing under the
Credit Facility. Our expected primary cash needs on both a short and long-term
basis are for investment in operational growth, capital expenditures, credit
facility repayments, share repurchases, selective strategic bolt-on
acquisitions, other investments, and other general corporate needs. We have
historically funded our operations and growth with cash flow from operations and
borrowings under our credit facilities. We expect to continue expanding our
operations through organic growth and potentially highly selective bolt-on
acquisitions and investments. As of March 31, 2023, cash commitments to support
operating business needs include lease liabilities discussed in Note 8 of the
Condensed Consolidated Financial Statements, short-term debt discussed in Note 7
of the Condensed Consolidated Financial Statements, purchase commitments
discussed in Note 11 of the Condensed Consolidated Financial Statements and
capital expenditures primarily related to infrastructure investments in our
facilities, equipment and technology. Capital spending as a percentage of
revenue decreased by 61 basis points to 2.19% in the three months ended
March 31, 2023, compared to the same period in the prior year. We expect these
activities will be funded from existing cash, cash flow from operations and, if
necessary, borrowings under our existing or future credit facilities or other
debt. We have deemed that foreign earnings will be indefinitely reinvested and
therefore we have not provided taxes on these earnings. While we do not
anticipate the need to repatriate these foreign earnings for liquidity purposes
given our cash flows from operations and borrowings under existing and future
credit facilities, we would incur taxes on these earnings if the need for
repatriation due to liquidity purposes arises.
