NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

June 30, 2021

(1) Basis of Presentation

Description of Business

Medpace Holdings, Inc. (together with its subsidiaries, “Medpace” or the “Company”), a Delaware corporation, is a global provider of clinical research-based drug and medical device development services. The Company partners with pharmaceutical, biotechnology, and medical device companies in the development and execution of clinical trials. The Company’s drug development services focus on full service Phase I-IV clinical development services and include development plan design, project management, regulatory affairs, clinical monitoring, data management and analysis, pharmacovigilance new drug application submissions, post-marketing clinical support, laboratory services, clinical human pharmacology, imaging services, and electrocardiography reading support for clinical trials.

The Company’s operations are principally based in North America, Europe, and Asia.

Unaudited Interim Financial Information

The interim condensed consolidated financial statements include the accounts of the Company, are prepared in conformity with U.S. generally accepted accounting principles (“GAAP”), and are unaudited. In the opinion of the Company’s management, all adjustments of a normal recurring nature necessary for a fair presentation have been reflected. Certain financial information that is normally included in annual financial statements prepared in accordance with GAAP, but that is not required for interim reporting purposes, has been omitted. The preparation of the interim condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the interim condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results and outcomes could differ from management’s estimates and assumptions. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.

Share Repurchases

In the first quarter of 2020, the Board of Directors approved an increase in the stock repurchase authorization by $50.0 million. In the fourth quarter of 2020, the Board approved the stock repurchase authorization up to $150.0 million. In the second quarter of 2021, the Board approved an increase of $150.0 million to the stock repurchase program bringing the total repurchase authorization up to $300.0 million. During the three and six months ended June 30, 2021, the Company repurchased 343,159 shares for $56.1 million, respectively. During the three and six months ended June 30, 2020, the Company repurchased 110,488 and 772,125 shares for $7.6 million and $50.8 million, respectively. As of June 30, 2021, we have remaining authorization of $196.4 million under the repurchase program.  

Repurchases under the share repurchase program are executed in the open market or negotiated transactions under trading plans put in place pursuant to Rule 10b5-1. The Company constructively retired the repurchased shares associated with these approved share repurchases, with all amounts paid in excess of par value reflected within Retained earnings in the Company’s condensed consolidated balance sheets. The repurchase program may be suspended or discontinued at any time without notice.  

Supplemental Cash Flow Disclosure

During the six months ended June 30, 2021, the Company engaged in a non-cash financing activity of $0.3 million related to share repurchases executed, but not yet paid as of period end.

Recently Adopted Accounting Standards

In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes.” The new guidance includes several provisions to reduce the complexity of accounting for income taxes for financial reporting purposes and increasing consistency and clarity for financial statement readers. The new guidance is effective for public entities for fiscal years, and the related interim periods, beginning after December 15, 2020. The Company adopted this standard in the first quarter of 2021 and it has no material impact on the condensed consolidated financial statements.

(2) Net Income Per Share

Basic and diluted earnings or loss per share (“EPS”) are computed using the two-class method, which is an earnings allocation that determines EPS for each class of common stock and participating securities according to dividends declared and participation rights in undistributed earnings. The Company’s Restricted Stock Awards (“RSA”) are considered participating securities because they are legally issued at the date of grant and holders are entitled to receive non-forfeitable dividends during the vesting term.

The computation of diluted EPS includes additional common shares, such as unvested Restricted Stock Units (“RSU”) and stock options with exercise prices less than the average market price of the Company’s common stock during the period (“in-the-money options”), which would be considered outstanding. This assumes that additional shares would have to be issued in cases where the exercise price of stock options is less than the value of the common stock being acquired because the cash proceeds received from the stock option holder would not be sufficient to acquire that same number of shares. The Company does not compute diluted EPS in cases where the inclusion of such additional shares would be anti-dilutive in effect.

The following table sets forth the computation of basic and diluted earnings per share for the three and six months ended June 30, 2021 and 2020 (in thousands, except for earnings per share): 

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2021		2020		2021		2020
Weighted-average shares:
Common shares outstanding		35,894		35,386		35,825		35,705
RSAs		114		95		115		95
Total weighted-average shares		36,008		35,481		35,940		35,800
Earnings per common share—Basic
Net income	$	39,934	$	24,104	$	83,240	$	53,058
Less: Undistributed earnings allocated to RSAs		127		65		267		141
Net income available to common shareholders—Basic	$	39,807	$	24,039	$	82,973	$	52,917
Net income per common share—Basic	$	1.11	$	0.68	$	2.32	$	1.48
Basic weighted-average common shares outstanding		35,894		35,386		35,825		35,705
Effect of diluted shares		1,820		1,942		1,912		1,975
Diluted weighted-average shares outstanding		37,714		37,328		37,737		37,680
Net income per common share—Diluted	$	1.06	$	0.64	$	2.20	$	1.40

During the three and six months ended June 30, 2021, the Company had 0 and 273,588 stock options, respectively, that were excluded due to the exercise price exceeding the average fair value of the Company’s common stock during the period. During the three and six months ended June 30, 2020, the Company had 439,405 stock options, respectively, that were excluded due to the exercise price exceeding the average fair value of the Company’s common stock during the period.

(3) Fair Value Measurements

The Company follows accounting guidance related to fair value measurements that defines fair value, establishes a framework for measuring fair value, and establishes a hierarchy for inputs used in measuring fair value. This hierarchy maximizes the use of “observable” inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. The hierarchy specifies three levels based on the inputs, as follows:

Level 1: Valuations based on quoted prices in active markets for identical assets or liabilities.

Level 2: Valuations based on directly observable inputs or unobservable inputs corroborated by market data.

Level 3: Valuations based on unobservable inputs supported by little or no market activity representing management’s determination of assumptions of how market participants would price the assets or liabilities. 

The fair value of financial instruments such as cash and cash equivalents, accounts receivable and unbilled, net, accounts payable, accrued expenses and advanced billings approximate their carrying amounts due to their short term maturities.

- 9 -

The Company does not have any recurring fair value measurements as of June 30, 2021. There were no transfers between Level 1, Level 2 or Level 3 during the three and six months ended June 30, 2021 or 2020.

(4) Contract Assets and Contract Liabilities

Contract assets and liabilities are reflected in the Company’s condensed consolidated balance sheets within the accounts reflected below.  

Contract Assets

Accounts receivable represent amounts due from the Company’s customers who are concentrated primarily in the pharmaceutical, biotechnology, and medical device industries. Unbilled represents revenue recognized to date that has not been billed or is not yet contractually billable to the customer. In general, amounts become billable upon the achievement of negotiated contractual events, in accordance with predetermined payment schedules or when a reimbursable expense has been incurred. Amounts classified to unbilled are those billable to customers within one year from the respective balance sheet date.

Accounts receivable and unbilled, net consisted of the following (in thousands):

	As of
	June 30,			December 31,
	2021			2020
Accounts receivable	$	127,696		$	137,912

Less: allowance for doubtful accounts		(346	)		(346	)
Total accounts receivable and unbilled, net	$	161,489		$	160,962

Contract Liabilities

Advanced billings represent cash received from customers, or billed amounts per an agreed upon payment schedule, in advance of services being performed or revenue being recognized.

Advanced billings consisted of the following (in thousands):

	As of
	June 30,		December 31,
	2021		2020
Advanced billings	$	282,217	$	255,664

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

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, 2020 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, 2020. 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, 2020.

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, including statements regarding our results of operations; financial position and performance; the anticipated impact of the coronavirus COVID-19 pandemic on our business; 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 operations, marketing, acquisitions and expansion of our business; product approvals and plans; industry trends; 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, are forward-looking statements. 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, 2020 and “Part II – Other Information, Item 1A Risk Factors” herein.

Business Overview

We are one of the world’s leading clinical contract research organizations, or CROs, by revenue, solely focused on providing scientifically-driven outsourced clinical development services to the biotechnology, pharmaceutical and medical device industries. Our mission is to accelerate the global development of safe and effective medical therapeutics. We differentiate ourselves from our competitors by our disciplined operating model centered on providing full-service Phase I-IV clinical development services and our therapeutic expertise. We believe this combination results in timely and cost-effective delivery of clinical development services for our customers. We believe that we are a partner of choice for small- and mid-sized biopharmaceutical companies based on our ability to consistently utilize our full-service, disciplined operating model to deliver timely and high-quality results for our customers.

We focus on conducting clinical trials across all major therapeutic areas, with particular strength in Oncology, Metabolic Disease, Cardiology, Antiviral and Anti-infective, or AVAI, and Central Nervous System, or CNS. Our global platform includes approximately 4,100 employees across 40 countries as of June 30, 2021, providing our customers with broad access to diverse markets and patient populations as well as local regulatory expertise and market knowledge.

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

- 17 -

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.

- 18 -

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 $387.6 million and $743.7 million for the three and six months ended June 30, 2021, respectively. Net new business awards were $254.1 million and $501.0 million for the three and six months ended June 30, 2020, 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 June 30, 2021, our backlog increased by $399.8 million, or 29.8%, to $1,742.6 million compared to $1,342.8 million as of June 30, 2020. Included within backlog as of June 30, 2021 was approximately $915 million to $935 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 $3.3 million for the three months ended June 30, 2021; unfavorable foreign currency adjustments of $0.4 million for six months ended June 30, 2021; unfavorable foreign currency adjustments of $0.2 million for the three months ended June 30, 2020; and unfavorable foreign currency adjustments of $4.1 million for the six months ended June 30, 2020.

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.

Coronavirus (COVID-19)

On March 11, 2020, the World Health Organization declared the coronavirus COVID-19 outbreak to be a pandemic. This pandemic increased travel restrictions and caused the shutdown of many businesses in countries in which we operate. While we continue to operate globally, the pandemic continues to impact our business and the level of activity at each of our locations varies depending on the local governmental requirements and guidelines which continue to evolve and change.

Our office staff are either effectively working remotely or in the office, and our labs are fully operational with modifications made to ensure the safety of our employees. The diversion of resources to treat COVID-19 patients continues to impact the operations at most of the investigative sites where patients in our clinical trials are recruited and treated.

Depending on the duration of the disruption, ongoing studies may be cancelled and some of our clients may lack the funding to complete trials which are extended due to slowed recruitment of patients. We work with many smaller clients with limited financial resources and market disruptions may make raising additional funds difficult for them. Travel restrictions and business closures continue to impact study participants and clinical sites which affects our ability to efficiently provide clinical trial services. We continue to work with our customers to develop solutions to limit disruption to clinical trials while following required regulatory guidelines and maintaining quality to ensure the health and well-being of study participants, including alternative assessment methods such as virtual monitoring visits.

While certain governments eased restrictions during the balance of 2020 and into 2021, the pandemic remains disruptive to our business operations. As we look ahead, we continue to expect impacts to our business to be temporary and primarily relate to limitations on our ability to physically access investigative sites, delays in patient enrollment and trial start-up activities.

The COVID-19 outbreak had a significant adverse effect on our results of operations and we believe that the outbreak may have a continued adverse impact on our results of operations in the future. As we cannot predict the duration or scope of the pandemic, the future financial impact on our results of operations and financial condition cannot be reasonably estimated.

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 expenses are subject to exchange rate fluctuations. We have translated the Euro into U.S. dollars using the following average exchange rates based on data obtained from www.xe.com:

Total revenue increased by $102.4 million to $538.3 million for the six months ended June 30, 2021, from $435.9 million for the six months ended June 30, 2020. The increase for the three months ended June 30, 2021 was primarily driven by growth within the Oncology, Central Nervous System, Metabolic and other uncategorized therapeutic areas, compared to the same period in the prior year.  The increase for the six months ended June 30, 2021 was primarily driven by growth within the Oncology, Central Nervous System, AVAI and other uncategorized therapeutic areas, compared to the same period in the prior year.

Total direct costs increased by $71.0 million, to $385.2 million for the six months ended June 30, 2021 from $314.2 million for the six months ended June 30, 2020. 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 $33.7 million and $36.8 million for the three and six month periods ended June 30, 2021, compared to the same periods in the prior year. The higher personnel costs portion, including severance, increased by $16.7 million and $25.4 million for the three and six months ended June 30, 2021, compared to the same periods in the prior year.

Selling, general and administrative

Selling, general and administrative expenses increased by $5.1 million, to $27.0 million for the three months ended June 30, 2021 from $21.9 million for the three months ended June 30, 2020. Selling, general and administrative expenses increased by $5.7 million, to $52.7 million for the six months ended June 30, 2021 from $47.0 million for the six months ended June 30, 2020.

Miscellaneous income, net

Miscellaneous income, net increased by less than $0.1 million to $0.3 million for the three months ended June 30, 2021 from $0.2 million for the three months ended June 30, 2020. Miscellaneous income, net increased by $0.3 million to $1.2 million for the six months ended June 30, 2021 from $0.9 million for the six months ended June 30, 2020. These changes were mainly attributable to foreign exchange gains or losses that arise in connection with the revaluation of short-term intercompany balances between our domestic and international subsidiaries, 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.

Interest (expense) income, net

Interest (expense) income, net increased by less than $0.1 million of expense to $0.0 million of expense for the three months ended June 30, 2021 from $0.0 million of expense for the three months ended June 30, 2020. Interest (expense) income, net increased by $0.4 million of expense to $0.0 million of expense for the six months ended June 30, 2021 from $0.4 million of income for the six months ended June 30, 2020.

Income tax provision

Income tax provision decreased by $3.5 million, to $2.8 million for the three months ended June 30, 2021 from $6.3 million for the three months ended June 30, 2020. Income tax provision decreased by $5.8 million, to $8.0 million for the six months ended June 30, 2021 from $13.8 million for the six months ended June 30, 2020. The overall effective tax rate for the three months ended June 30, 2021 was 6.4%, compared to an overall effective tax rate of 20.6% for the three months ended June 30, 2020. The overall effective tax rate for the six months ended June 30, 2021 was 8.7%, compared to an overall effective tax rate of 20.6% for the six months ended June 30, 2020. The decrease in the income tax provision and overall effective tax rate was primarily attributable to an increase in excess tax benefits recognized from share-based compensation and an increase in tax benefits related to Foreign Derived Intangible Income (FDII) 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 funds available for borrowing under our unsecured credit facility consisting of up to a $50.0 million revolving line of credit which we entered into on September 30, 2019 (the “Credit Facility”). As of June 30, 2021, we had cash and cash equivalents of $339.0 million. Approximately $28.1 million of cash and cash equivalents, none of which was restricted, was held by our foreign subsidiaries as of June 30, 2021. On March 29, 2021, we extended the expiration date of the Credit Facility to March 31, 2022.

As of June 30, 2021, we had $49.8 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, 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. 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. 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 available borrowing under existing and future credit facilities, we would incur taxes on these earnings if the need for repatriation due to liquidity purposes arises.

Cash Flow from Operating Activities

Cash flows from operations are driven mainly by net income, stock based compensation expense, amortization of intangibles and net movement in advanced billings, accrued expenses, prepaid expenses and other current assets, and accounts receivable and unbilled, net. Accounts receivable and unbilled, net and advanced billings fluctuate on a regular basis as we perform our services, bill our customers and ultimately collect on those receivables. We attempt to negotiate payment terms in order to provide for payments prior to or soon after the provision of services, but this timing of collection can vary significantly on a period by period comparative basis.

Net cash flows provided by operating activities was $120.1 million for the six months ended June 30, 2021 beginning with net income of $83.2 million. Adjustments to reconcile net income to net cash provided by operating activities were $27.2 million, primarily related to noncash lease expense of $7.9 million, depreciation of $7.8 million, stock based compensation expense of $6.4 million and amortization of intangibles of $2.6 million. Changes in operating assets and liabilities provided $9.7 million in operating cash flows and was primarily driven by increased advanced billings of $26.6 million and accrued expenses of $11.9 million, offset by increased prepaid expenses and other current assets of $14.9 million and decreased lease liabilities of $8.0 million.  

Net cash flows provided by operating activities was $93.4 million for the six months ended June 30, 2020 beginning with net income of $53.1 million. Adjustments to reconcile net income to net cash provided by operating activities were $25.2 million, primarily related to stock based compensation expense of $8.1 million, noncash lease expense of $6.3 million, depreciation of $5.1 million and amortization of intangibles of $4.0 million. Changes in operating assets and liabilities provided $15.1 million in operating cash flows and was primarily driven by decreased accounts receivable and unbilled, net of $28.5 million, offset by decreased accounts payable of $7.2 million and decreased accrued expenses of $5.9 million.

Cash Flow from Investing Activities

Net cash used in investing activities was $15.6 million for the six months ended June 30, 2021 primarily consisting of $12.5 million in property and equipment expenditures.

Net cash used in financing activities was $48.9 million for the six months ended June 30, 2020 primarily related to $50.8 million in repurchases on common stock.

Share Repurchases

In the first quarter of 2020, the Board of Directors approved an increase in the stock repurchase authorization by $50.0 million. In the fourth quarter of 2020, the Board approved the stock repurchase authorization up to $150.0 million. In the second quarter of 2021, the Board approved an increase of $150.0 million to the stock repurchase program bringing the total repurchase authorization up to $300.0 million. During the three and six months ended June 30, 2021, the Company repurchased 343,159 shares for $56.1 million, respectively.

As of June 30, 2021, we have remaining authorization of $196.4 million under the repurchase program.

Repurchases under the share repurchase program are executed in the open market or negotiated transactions under trading plans put in place pursuant to Rule 10b5-1. The Company constructively retired the repurchased shares associated with these approved share repurchases, with all amounts paid in excess of par value reflected within Retained earnings in the Company’s condensed consolidated balance sheets. The repurchase program may be suspended or discontinued at any time without notice.

Contractual Obligations and Commercial Commitments

We have various contractual obligations, which are recorded as liabilities in our condensed consolidated financial statements. Other items are not recognized as liabilities in our condensed consolidated financial statements but are required to be disclosed. There have been no material changes, outside of the ordinary course of business, to our contractual obligations as previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

Off-Balance Sheet Arrangements

Off-balance sheet arrangements refer to any transaction, agreement or other contractual arrangement to which an entity not consolidated under our entity structure exists, where we have an obligation arising under a guarantee contract, derivative instrument or variable interest or a retained or contingent interest in assets transferred to such an entity or similar arrangement that serves as credit, liquidity or market risk support for such assets. We have no off-balance sheet arrangements currently.

Critical Accounting Policies and Estimates

The preparation of financial statements in accordance with generally accepted accounting principles in the United States of America, or U.S. GAAP, requires us to make a variety of decisions which affect reported amounts and related disclosures, including the selection of appropriate accounting principles and the assumptions on which to base accounting estimates. In reaching such decisions, we apply judgment based on our understanding and analysis of the relevant circumstances, including our historical experience and other assumptions. Actual results could differ from our estimates. We are committed to incorporating accounting principles, assumptions and estimates that promote the representational faithfulness, verifiability, neutrality and transparency of the accounting information included in the financial statements.

There have been no significant changes in the critical accounting policies and estimates as previously described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

Effect of Recent Accounting Pronouncements

Refer to Note 1 of the Condensed Consolidated Financial Statements for management’s discussion of the effect of recent accounting pronouncements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

There have been no material changes to our quantitative and qualitative disclosures about market risk as compared to the quantitative and qualitative disclosures about market risk described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

Item 4. Controls and Procedures

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Evaluation of Disclosure Controls and Procedures

The Company’s management, with the participation of the President and Chief Executive Officer (the Principal Executive Officer) and Chief Financial Officer (the Principal Financial Officer), has evaluated the effectiveness of the Company’s disclosure controls and procedures, as defined in Rules 13(a)-15(e) and 15(d) -15(e) of the Securities Exchange Act of 1934 (Exchange Act), as of the end of the period covered by this report. Based on this evaluation, we concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective in providing reasonable assurance that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s forms and rules, and the material information relating to the Company is accumulated and communicated to management, including the President and Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.

Control systems, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that control objectives are met. Because of inherent limitations in all control systems, no evaluation of controls can provide assurance that all control issues and instances of fraud, if any, within a company will be detected. Additionally, controls can be circumvented by

- 24 -

individuals, by collusion of two or more people or by management override. Over time, controls can become inadequate because of changes in conditions or the degree of compliance may deteriorate. Further, the design of any system of controls is based in part upon assumptions about the likelihood of future events. There can be no assurance that any design will succeed in achieving its stated goals under all future conditions. Because of the inherent limitations in any cost-effective control system, misstatements due to errors or fraud may occur and not be detected.

Changes in Internal Control over Financial Reporting

In the ordinary course of business, we routinely enhance our information systems by either upgrading current systems or implementing new ones. There were no changes in our internal control over financial reporting that occurred during the three months ended June 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings

We are party to legal proceedings incidental to our business. While the outcome of these matters could differ from management’s expectations, we do not believe that the resolution of these matters is reasonably likely to have a material adverse effect to our financial statements.

Item 1A. Risk Factors

For a discussion of our potential risks and uncertainties, see the information under the heading “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020. There have been no significant changes from the risk factors previously disclosed in our Annual Report.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Description of Business

Medpace Holdings, Inc. (together with its subsidiaries, “Medpace” or the “Company”), a Delaware corporation, is a global provider of clinical research-based drug and medical device development services. The Company partners with pharmaceutical, biotechnology, and medical device companies in the development and execution of clinical trials. The Company’s drug development services focus on full service Phase I-IV clinical development services and include development plan design, project management, regulatory affairs, clinical monitoring, data management and analysis, pharmacovigilance new drug application submissions, post-marketing clinical support, laboratory services, clinical human pharmacology, imaging services, and electrocardiography reading support for clinical trials.

The Company’s operations are principally based in North America, Europe, and Asia.

Unaudited Interim Financial Information

The interim condensed consolidated financial statements include the accounts of the Company, are prepared in conformity with U.S. generally accepted accounting principles (“GAAP”), and are unaudited. In the opinion of the Company’s management, all adjustments of a normal recurring nature necessary for a fair presentation have been reflected. Certain financial information that is normally included in annual financial statements prepared in accordance with GAAP, but that is not required for interim reporting purposes, has been omitted. The preparation of the interim condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the interim condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results and outcomes could differ from management’s estimates and assumptions. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.

The new guidance is effective for public entities for fiscal years, and the related interim periods, beginning after December 15, 2020. The Company adopted this standard in the first quarter of 2021 and it has no material impact on the condensed consolidated financial statements.

Earnings Per Share [Abstract]

Net Income Per Share

(2) Net Income Per Share

Basic and diluted earnings or loss per share (“EPS”) are computed using the two-class method, which is an earnings allocation that determines EPS for each class of common stock and participating securities according to dividends declared and participation rights in undistributed earnings. The Company’s Restricted Stock Awards (“RSA”) are considered participating securities because they are legally issued at the date of grant and holders are entitled to receive non-forfeitable dividends during the vesting term.

The computation of diluted EPS includes additional common shares, such as unvested Restricted Stock Units (“RSU”) and stock options with exercise prices less than the average market price of the Company’s common stock during the period (“in-the-money options”), which would be considered outstanding. This assumes that additional shares would have to be issued in cases where the exercise price of stock options is less than the value of the common stock being acquired because the cash proceeds received from the stock option holder would not be sufficient to acquire that same number of shares. The Company does not compute diluted EPS in cases where the inclusion of such additional shares would be anti-dilutive in effect.

The following table sets forth the computation of basic and diluted earnings per share for the three and six months ended June 30, 2021 and 2020 (in thousands, except for earnings per share):

Fair Value Measurements

(3) Fair Value Measurements

The Company follows accounting guidance related to fair value measurements that defines fair value, establishes a framework for measuring fair value, and establishes a hierarchy for inputs used in measuring fair value. This hierarchy maximizes the use of “observable” inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. The hierarchy specifies three levels based on the inputs, as follows:

Level 1: Valuations based on quoted prices in active markets for identical assets or liabilities.

Level 2: Valuations based on directly observable inputs or unobservable inputs corroborated by market data.

Level 3: Valuations based on unobservable inputs supported by little or no market activity representing management’s determination of assumptions of how market participants would price the assets or liabilities. 

The fair value of financial instruments such as cash and cash equivalents, accounts receivable and unbilled, net, accounts payable, accrued expenses and advanced billings approximate their carrying amounts due to their short term maturities.

The Company does not have any recurring fair value measurements as of June 30, 2021. There were no transfers between Level 1, Level 2 or Level 3 during the three and six months ended June 30, 2021 or 2020.

The Company pays rent, taxes, insurance, and maintenance expenses that arise from the use of the property.

Accounting Policies [Abstract]

Unaudited Interim Financial Information

Unaudited Interim Financial Information

The interim condensed consolidated financial statements include the accounts of the Company, are prepared in conformity with U.S. generally accepted accounting principles (“GAAP”), and are unaudited. In the opinion of the Company’s management, all adjustments of a normal recurring nature necessary for a fair presentation have been reflected. Certain financial information that is normally included in annual financial statements prepared in accordance with GAAP, but that is not required for interim reporting purposes, has been omitted. The preparation of the interim condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the interim condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results and outcomes could differ from management’s estimates and assumptions. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.

Share Repurchases

In the first quarter of 2020, the Board of Directors approved an increase in the stock repurchase authorization by $50.0 million. In the fourth quarter of 2020, the Board approved the stock repurchase authorization up to $150.0 million. In the second quarter of 2021, the Board approved an increase of $150.0 million to the stock repurchase program bringing the total repurchase authorization up to $300.0 million. During the three and six months ended June 30, 2021, the Company repurchased 343,159 shares for $56.1 million, respectively. During the three and six months ended June 30, 2020, the Company repurchased 110,488 and 772,125 shares for $7.6 million and $50.8 million, respectively. As of June 30, 2021, we have remaining authorization of $196.4 million under the repurchase program.  

Repurchases under the share repurchase program are executed in the open market or negotiated transactions under trading plans put in place pursuant to Rule 10b5-1. The Company constructively retired the repurchased shares associated with these approved share repurchases, with all amounts paid in excess of par value reflected within Retained earnings in the Company’s condensed consolidated balance sheets. The repurchase program may be suspended or discontinued at any time without notice.  

Supplemental Cash Flow Disclosure

During the six months ended June 30, 2021, the Company engaged in a non-cash financing activity of $0.3 million related to share repurchases executed, but not yet paid as of period end.

Recently Adopted Accounting Standards

Recently Adopted Accounting Standards

In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes.” The new guidance includes several provisions to reduce the complexity of accounting for income taxes for financial reporting purposes and increasing consistency and clarity for financial statement readers. The new guidance is effective for public entities for fiscal years, and the related interim periods, beginning after December 15, 2020. The Company adopted this standard in the first quarter of 2021 and it has no material impact on the condensed consolidated financial statements.
