重新定價-高級擔保期貸款設施和高級擔保循環信貸設施

2021年7月1日，與PRA公司合併有關，icon plc及其某些子公司簽訂了一份信貸協議（「信貸協議」），該協議規定了一項高級擔保期貸款設施，金額爲5515百萬美元，以及一個最初總額爲3000百萬美元的高級擔保循環信貸設施（後於2023年5月2日增加至5000百萬美元）。

2024年3月14日，信貸協議的各方簽署了信貸協議的第三次修訂（「第三次修訂」），以重新定價高級擔保期貸款設施和高級擔保循環信貸設施。

就優先擔保定期貸款機制而言，重新定價最終導致利潤率降低了25個點子，從2.25％（基於當時的第一留置權淨槓桿比率）降至2.0％；並取消了信貸調整利差。上述因素相結合，導致優先擔保定期貸款額度總體減少了51個點子（假設按季度重新調整）。

With respect to the senior secured revolving credit facility, the repricing culminated in a margin reduction of 0.40%, from 1.25% (based on the then-current S&P corporate family rating) to 0.85%, which is subject to change pursuant to a pricing grid based on the current corporate family rating assigned by S&P; and the elimination of the credit adjustment spread. There were also concurrent fee adjustments to the senior secured revolving credit facility; the commitment fee on drawings was reduced from 0.4375% to 0.2975%, (based on our current corporate family rating from S&P) while the utilization fee increased by 15 basis points, dependent on amount utilized.

Senior Secured Credit Facilities repayment

During the quarter ended September 30, 2024, the Company made mandatory principal repayments of $7.4 million (nine months ended September 30, 2024: mandatory and voluntary repayments of $2,297.3 million) of the senior secured term loan facility. The voluntary repayments made during the nine months ended September 30, 2024 resulted in an accelerated charge associated with previously capitalized fees of $16.9 million.

In addition, during the quarter ended September 30, 2024, the Company drew $50.0 million (nine months ended September 30, 2024: $243.0 million) of the senior secured revolving loan facility and repaid $50.0 million (nine months ended September 30, 2024: $298.0 million). At September 30, 2024, $nil was drawn under the senior secured revolving loan facility. Refer to note 10. Bank credit lines, loan facilities and notes for further details on the Company's Senior Secured Credit Facilities.

Ukraine situation

On February 24, 2022, Russia invaded Ukraine, creating significant instability and unrest in the region. Since that time, the Company's key focus has been on the safety of our employees and their families, patients, investigators and on the mitigation of adverse impacts on ongoing clinical trials. The Company has worked to ensure the safety of employees and their families based in Ukraine through the implementation of a number of employee assistance programs. These programs aim to provide affected employees and their families with transportation, accommodation in neighboring countries, financial assistance, communications and other support services as needed.

The Company's operations in these affected regions have been significantly curtailed as a result of these events. The ongoing conflict in Ukraine continues to result in an increasingly complex economic sanctions and export controls environment applicable to our business operations in the region (including Russia and Belarus) as a result of additional trade compliance measures enacted by the United States, United Kingdom and European Union member states. These economic sanctions and export controls restrict our ability to do business with sanctioned entities, require additional compliance resources, and could have a material adverse effect on the results of our operations. The financial impact of the conflict was not material to the Company during the nine months ended September 30, 2024.

Israel and the conflict area in the Middle East

We are all saddened by the continuing developments in Israel and the conflict area in the Middle East. The Company's key focus continues to be on the safety of our employees and their families, patients, investigators and on the mitigation of adverse impacts on ongoing clinical trials. The Company has worked to ensure the safety of employees and their families through the implementation of a number of employee assistance programs. The team have been advised to work remotely as they continue to support our customers’ studies. The financial impact of the conflict was not material to the Company during the nine months ended September 30, 2024.

Foreign exchange translation
The Company prepares its financial statements in United States dollar while the local results of a certain number of our subsidiaries are prepared in currencies other than United States dollars, including, amongst others, the pound sterling and the euro. In addition, the Company's contracts with clients are sometimes denominated in currencies other than the United States dollar. Finally, the Company is exposed to a wider variety of currencies in the expenses line due to most expenses being incurred in the local currencies of where our global operations are based. Accordingly, changes in exchange rates between the United States dollar and those other currencies can impact the Company’s financial results.

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)
September 30, 2024
1. Basis of presentation

These condensed consolidated financial statements which have been prepared in accordance with United States Generally Accepted Accounting Principles (“US GAAP”) have not been audited. The condensed consolidated financial statements reflect all adjustments, which are, in the opinion of management, necessary to present a fair statement of the operating results and financial position for the periods presented. The preparation of the condensed consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect reported amounts and disclosures in the condensed consolidated financial statements. Actual results could differ from those estimates.

The condensed consolidated financial statements should be read in conjunction with the accounting policies and notes to the consolidated financial statements included in ICON’s Form 20-F for the year ended December 31, 2023 (see note 2 - Summary of significant accounting policies). Operating results for the nine months ended September 30, 2024 are not necessarily indicative of the results that may be expected for the fiscal period ending December 31, 2024.
2. Summary of significant accounting policies
Revenue recognition
The Company earns revenues by providing a number of different services to its customers. These services, which are integral elements of the clinical development process, include clinical trials management, consulting, contract staffing, data services and laboratory services. These services, which are described below, can be purchased collectively or individually as part of a clinical trial contract. There is not significant variability in how economic factors affect these services. Contracts range in duration from a number of months to several years.

ASC 606 requires application of five steps: (1) identify the contract(s) with a customer; (2) identify the performance obligation in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies the performance obligation(s), which have been applied to revenue recognized from each service described below.

Clinical trial service revenue

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

Laboratory services revenue

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

Contracting services revenue

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

Consulting services revenue

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

Data services revenue

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

When multiple performance obligations exist, the transaction price is allocated to performance obligations on a relative standalone selling price basis. In cases where the Company contracts to provide a series of data reports, or in some cases data, the Company recognizes revenue over time using the “units delivered” output method as the data or reports are delivered. Expense reimbursements are recorded to revenue as the expenses are incurred as they relate directly to the services performed.

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

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

Commissions

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

Intangible Assets
Intangible assets are measured at fair value at the date of acquisition and amortized on a straight-line basis over their respective estimated useful lives. The Company has no indefinite-lived intangible assets. The Company evaluates its intangible assets for impairment when indicators of impairment exist.

Intangible assets are amortized on a straight-line basis over their estimated useful lives, as set forth in the table below:

Estimated Useful Life
Customer relationships
16 - 23 years
Order backlog3 years
Trade names3 years
Patient database7 years
Technology assets5 years

The Company periodically assesses the estimated useful lives of intangible assets to evaluate whether what was established at acquisition continues to be appropriate.

Income taxes

The Company applies the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amount of existing assets and liabilities and their respective tax bases and for operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the provision of income taxes in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance to the amount that is more likely than not to be realized. The Company recognizes the effect of income tax positions only if those positions will more likely than not be sustained. Recognized income tax positions are measured at the largest amount of tax benefit that is greater than 50 percent likely of being realized upon settlement. Interest and penalties related to income taxes are included in income tax expense and classified with the related liability on the Consolidated Balance Sheet. The Company accounts for the impact of Global Intangible Low-Taxed Income ("GILTI") in the period it arises and has therefore not provided for deferred taxes in respect of this item.

Recently Issued Accounting Standards

Accounting pronouncements issued but not adopted as of September 30, 2024

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting – Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which amends the guidance in ASC Topic 280, Segment Reporting. The amended guidance requires disclosure of significant segment expenses and other segment items on an annual and interim basis. Furthermore, all disclosures about a reportable segment’s profit or loss, which are currently required annually, will be mandated for interim periods. The additional disclosures required by ASU 2023-07 apply to entities with a single reportable segment. The amended guidance is effective for fiscal periods beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with retrospective application required. The Company is currently evaluating the impact of this ASU on disclosures within its consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which requires disaggregated information about an entity’s effective tax rate reconciliation and additional discloses on income taxes paid. The new requirements are effective for annual periods beginning after December 15, 2024. The guidance is to be applied prospectively, with an option for retrospective application. The Company is currently evaluating the impact of this new guidance on disclosures within its consolidated financial statements.

Net balance$(224,059)$(702,571)$478,512 (68.1)%

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

Unbilled services/revenue balances arise where invoicing or billing is based on the timing of agreed milestones related to service contracts for clinical research. Contractual billing arrangements in respect of certain reimbursable expenses (principally investigators) require billing by the investigator to the Company prior to billing by the Company to the customer. As there is no contractual right to set-off between unbilled services (contract assets) and unearned revenue (contract liabilities), each are separately presented gross on the Condensed Consolidated Balance Sheet.

Unbilled services as at September 30, 2024 increased by $409.3 million compared to December 31, 2023. Unearned revenue decreased by $69.3 million over the same period resulting in a decrease of $478.5 million in the net balance of unbilled services and unearned revenue or payments on account between December 31, 2023 and September 30, 2024. These fluctuations are primarily due to timing of payments and invoicing related to the Group's clinical trial management contracts. Billings and payments are established by contractual provisions including predetermined payment schedules which may or may not correspond to the timing of the transfer of control of the Company's services under the contract. Unbilled services arise from long-term contracts when a cost-based input method of revenue recognition is applied and revenue recognized exceeds the amount billed to the customer.

As of September 30, 2024, approximately $15.5 billion (September 30, 2023: $14.3 billion) of revenue is expected to be recognized in the future in respect of unsatisfied performance obligations. The Company expects to recognize revenue on approximately 51% of the unsatisfied performance obligations over the next 12 months (September 30, 2023: 51%), with the remainder recognized thereafter over the duration of the customer contracts.

The identifiable intangible assets are amortized over their estimated useful lives.

7. Fair value measurements

The Company records certain assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. A three-level fair value hierarchy that prioritizes the inputs used to measure fair value is described below. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

•Level 1 — Quoted prices in active markets for identical assets or liabilities.
•Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.
•Level 3 — Unobservable inputs that are supported by little or no market activity. This includes certain pricing models, discounted cash flow methodologies, and similar techniques that use significant unobservable inputs.

The carrying amounts of financial instruments, including cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to the short maturities of these instruments.

(a) Represents the fair value of highly liquid investments with maturities greater than three months, a minimum "A-" rated fixed term deposit and are based on quoted market prices.

(b) To determine the classification of its investments in equity, the Company considered the nature of its investment, the extent of influence over operating and financial decisions and the availability of readily determinable fair values. The Company determined that certain interests in funds meet the definition of equity securities without readily determinable fair values, which qualify for the Net Asset Value (NAV) practical expedient in ASC 820 'Fair value measurement'. Any increases or decreases in fair value are recognized in net income in the period.

(c) Represents the fair value of the interest rate caps and the interest rate swap.

Non-recurring Fair Value Measurements

Certain assets and liabilities are carried on the accompanying Condensed Consolidated Balance Sheet at cost and are not re-measured to fair value on a recurring basis. These assets include finite-lived intangible assets that are tested for impairment when a triggering event occurs and goodwill that is tested for impairment annually or when a triggering event occurs. As of September 30, 2024, assets carried on the Condensed Consolidated Balance Sheet which are not re-measured to fair value on a recurring basis totaled $12,691.2 million (December 31, 2023: $12,878.0 million) and are identified as Level 3 assets. These assets are comprised of goodwill of $9,085.4 million (December 31, 2023: $9,022.1 million) and net identifiable intangible assets of $3,605.8 million (December 31, 2023: $3,855.9 million).

The estimated fair value of the Company’s debt was $3,538.9 million at September 30, 2024 (December 31, 2023: $3,793.5 million). The fair values of the Senior Secured Credit Facilities, the 2026 Notes and the New Notes were determined based on Level 2 inputs, which are based on rates at which the debt is traded among financial institutions. The fair value of the senior secured revolving loan facility is recorded as its carrying value, due to the short term duration. Refer to note 10. Bank credit lines, loan facilities and notes for further details on the Company's financing arrangements.

The Company's primary financing arrangements are its senior secured credit facilities (the "Senior Secured Credit Facilities"), which consists of a senior secured term loan and a revolving credit facility, the 2026 Notes and the New Notes.

The New Notes

On May 8, 2024, ICON Investments Six Designated Activity Company (the "Issuer"), a wholly-owned subsidiary of ICON plc, issued $2 billion senior secured notes ("the New Notes"). The New Notes were issued in aggregate principal amounts of: $750 million 5.809% Senior Secured Notes due 2027 (the "2027 Notes"), $750 million 5.849% Senior Secured Notes due 2029 (the "2029 Notes") and $500 million 6.000% Senior Secured Notes due 2034 (the "2034 Notes").

The Company paid an underwriting discount of $6.8 million on the New Notes being: 0.250% of the principal amount of the 2027 Notes, 0.350% of the principal amount of the 2029 Notes and 0.450% of the 2034 Notes. Further, the 2034 Notes were issued at a discount of $0.5 million (issued at 99.896% of par).

The proceeds from the issuance were used to repay a portion of the senior secured term loan outstanding under the Senior Secured Credit Facilities and to pay fees, costs and expenses related to the offering.

Interest on the New Notes is payable on May 8 and November 8 of each year, commencing on November 8, 2024. Unless previously redeemed, the 2027 Notes will mature on May 8, 2027, the 2029 Notes will mature on May 8, 2029 and the 2034 Notes will mature on May 8, 2034.

The New Notes are guaranteed on a senior secured basis by ICON and its existing and future wholly owned subsidiaries, in each case that guarantee the obligations under our Senior Secured Credit Facilities and the 2026 Notes. The New Notes are the senior secured obligation of the Issuer and the Guarantors and rank equally in right of payment to all of the Issuer’s and Guarantors’ existing and future senior debt and senior in right of payment to all of the Issuer's and Guarantors' existing and future subordinated debt. The New Notes and the guarantees are secured on a first-lien basis by substantially all of the existing and future assets of the Issuer and the Guarantors that also secure the Issuer’s and the Guarantors’ obligations under the Senior Secured Credit Facilities and the 2026 Notes on a pari passu basis, subject to permitted liens, and the liens on the collateral securing the New Notes rank equally in priority with the liens on the collateral securing borrowings and guarantees under the Senior Secured Credit Facilities, the 2026 Notes and any other future pari passu first lien indebtedness.

Senior Secured Credit Facilities

On July 1, 2021, the Company completed the acquisition of PRA Health Sciences, Inc. ("PRA") by means of a merger whereby Indigo Merger Sub, Inc., a Delaware corporation and subsidiary of ICON, merged with and into PRA, the parent of the PRA Health Sciences ("the Merger"). In conjunction with the completion of the Merger, on July 1, 2021, ICON entered into a credit agreement providing for a senior secured term loan facility of $5,515 million and a senior secured revolving loan facility in an initial aggregate principal amount of $300 million (the "Senior Secured Credit Facilities"). On May 2, 2023, the Company agreed with its lenders to increase the aggregate principal amount of the senior secured revolving loan facility from $300 million to $500 million.

Borrowings under the senior secured term loan facility amortize in equal quarterly installments in an amount equal to 1.00% per annum of the principal amount, with the remaining balance due at final maturity. The interest rate margin applicable to borrowings under the senior secured term loan facility is USD Term SOFR and a Term SOFR Adjustment depending on the interest period chosen plus an applicable margin which is dependent on the Company's net leverage ratio. At September 30, 2024, the applicable margin is 2.0% (which reflects the Third Amendment). The senior secured term loan facility is subject to a floor of 0.50%.

Reflecting the Third Amendment, the interest rate margin applicable to borrowings under the revolving loan facility will be, at the option of the borrower, either (i) the applicable base rate plus an applicable margin of 0.45%, 0.10% or –% based on the Company’s current corporate family rating assigned by S&P of BB (or lower), BB+ or BBB- (or higher), respectively, or (ii) Term SOFR plus a Term SOFR Adjustment on the interest period chosen plus an applicable margin of 1.45%, 1.10%, 0.85%, 0.65%, or 0.50% based on the Company’s current corporate family rating assigned by S&P of BB (or lower), BB+, BBB-, BBB or BBB+ (or higher), respectively. In addition, lenders under the revolving loan facility are entitled to commitment fees as a percentage of the applicable margin at the time of drawing and utilization fees dependent on the proportion of the facility drawn.

The Borrowers’ (as defined in the Senior Secured Credit Facility) obligations under the Senior Secured Credit Facilities are guaranteed by ICON and the subsidiary guarantors. The Senior Secured Credit Facilities are secured by a lien on substantially all of ICON’s, the Borrowers’ and each of the subsidiary guarantor’s assets (subject to certain exceptions), and the Senior Secured Credit Facilities will have a first-priority lien on such assets, which will rank pari passu with the lien securing the 2026 Notes and the New Notes subject to other permitted liens. The Company is permitted to make prepayments on the senior secured term loan without penalty.

Principal repayments, comprising mandatory and voluntary repayments, during the nine months ended September 30, 2024 and year ended December 31, 2023 were as follows:

Principal repayments(in thousands)

2026 Notes

In addition to the Senior Secured Credit Facilities, on July 1, 2021, a subsidiary of the Company issued $500 million in aggregate principal amount of 2.875% senior secured notes (the "2026 Notes") in a private offering (the “Offering”). The 2026 Notes will mature on July 15, 2026.

Fair Value of Debt

The estimated fair value of the Company’s debt was $3,538.9 million at September 30, 2024 (December 31, 2023: $3,793.5 million). The fair values of the Senior Secured Credit Facilities, the 2026 Notes and the New Notes were determined based on Level 2 inputs, which are based on rates at which the debt is traded among financial institutions. The fair value of the senior secured revolving loan facility is recorded as its carrying value due to the short term duration.

11. Derivatives

The Company previously entered into interest rate cap and swap agreements for purposes of managing its exposure to interest rate fluctuations.

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

On November 29, 2022, the Company entered into an interest rate swap agreement ("2022 Swap") with an initial notional value of $1,101 million to limit its exposure to changes in the variable interest rate on its Senior Secured Credit Facilities. Interest on the 2022 Swap was due to begin accruing on December 31, 2024 and the interest rate swap was due to expire on September 30, 2026. Under the terms of the interest rate swap, the Company would have paid a fixed rate of 3.4% and would have received a variable rate of interest equal to the three-month SOFR on the 2022 Swap.

The 2022 Caps and the 2022 Swap were designated as cash flow hedges. Gains and losses were initially reported as a component of other comprehensive income/loss and subsequently recognized in net income.

During the quarter ended June 30, 2024, the Company’s exposure to interest rate fluctuations significantly reduced with the voluntary and mandatory repayments made of $2,014.9 million of the senior secured term loan facility. Given this reduction and the repricing of the Senior Secured Credit facilities (which occurred during the quarter ended March 31, 2024), the Company closed the 2022 Caps and 2022 Swap agreements.

As at September 30, 2024, 72% of the Company’s outstanding debt is at a fixed interest rate (December 31, 2023: 13%).

As of June 30, 2024, following the closure of the interest rate caps and interest rate swap, the Company derecognized the derivative positions (December 31, 2023: current derivative liability of $1.9 million within Other Liabilities and a non-current derivative liability of $0.5 million within Non-Current Other Liabilities).

During the three months ended September 30, 2024, the Company recognized a loss of $0.2 million (September 30, 2023: $5.0 million gain) within other comprehensive income/loss after a reclassification of $0.2 million gain (September 30, 2023: $0.3 million) from other comprehensive income/loss to the income statement.

During the nine months ended September 30, 2024, the Company recognized a gain of $4.8 million (September 30, 2023: $15.1 million) within other comprehensive income/loss after a reclassification of $13.7 million gain (September 30, 2023: $3.3 million) from other comprehensive income/loss to the income statement.

The fair value of the Company’s derivative financial instruments at December 31, 2023 ($nil at September 30, 2024), on a gross basis, are summarized in the following table:

As at September 30, 2024 the Company maintains a $201.4 million liability (December 31, 2023: $187.1 million) for unrecognized tax benefit, which is comprised of $164.2 million (December 31, 2023: $160.0 million) related to items generating unrecognized tax benefits and $37.2 million (December 31, 2023: $27.1 million) for interest and penalties related to such items. The Company recognizes interest accrued on unrecognized tax benefits as an additional income tax expense.

The Company has analyzed the filing positions in all of the significant federal, state and foreign jurisdictions where it is required to file income tax returns, as well as open tax years in these jurisdictions. The only periods subject to audit by the major tax jurisdictions where the Company does business are the 2015 through 2023 tax years. During such audits, local tax authorities may challenge the positions taken by us in our tax returns.
13. Net income per ordinary share

Basic net income per ordinary share attributable to the Group has been computed by dividing net income available to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period.

Diluted net income per ordinary share is computed by adjusting the weighted average number of ordinary shares outstanding during the period for all potentially dilutive ordinary shares outstanding during the period and adjusting net income for any changes in income or loss that would result from the conversion of such potential ordinary shares.

There is no difference in net income used for basic and diluted net income per ordinary share.

The reconciliation of the number of shares used in the computation of basic and diluted net income per ordinary share is as follows:

The Company issues ordinary shares for all options exercised. The total amount of fully vested share options which remained outstanding at September 30, 2024 was 461,732. Fully vested share options at September 30, 2024 have an average remaining contractual term of 3.48 years and an average exercise price of $133.30.

Fair value of Stock Options Assumptions

The weighted average fair value of options granted during the nine months ended September 30, 2024 and September 30, 2023 was calculated using the Black-Scholes option pricing model. The weighted average grant date fair values and assumptions used were as follows:
Nine Months Ended

Assumptions:  
Expected volatility36 %33 %
Dividend yield— %— %
Risk-free interest rate4.20 %4.18 %

Expected volatility is based on the historical volatility of our common stock over a period equal to the expected term of the options; the expected life represents the weighted average period of time that options granted are expected to be outstanding given consideration to vesting schedules and our historical experience of past vesting and termination patterns. The risk-free rate is based on the U.S. government zero-coupon bonds yield curve in effect at time of the grant for periods corresponding with the expected life of the option.

Restricted Share Units and Performance Share Units 

On April 23, 2013, the Company adopted the 2013 Employees Restricted Share Unit and Performance Share Unit Plan (the "2013 RSU Plan") pursuant to which the Compensation and Organization Committee of the Company's Board of Directors may select any employee, or any Director holding a salaried office or employment with the Company, or a subsidiary to receive an award under the plan. On May 11, 2015, the 2013 RSU Plan was amended and restated in order to increase the number of shares that can be issued under the 2013 RSU Plan by 2.5 million shares.

15. Share capital

The Company can acquire up to 10% of its outstanding ordinary shares (by way of redemption), in accordance with Irish law and the Company’s constitutional documents through open market share acquisitions.

On February 20, 2024, the Company's Board of Directors authorized a new buyback program of up to $500 million of the outstanding ordinary shares of the Company. All ordinary shares that are redeemed under the buyback program will be canceled in accordance with the constitutional documents of the Company and the nominal value of these shares transferred to an undenominated capital fund as required under Irish Company law. Repurchases under the share buyback program may be effected from time to time in open market or privately negotiated transactions in accordance with agreed terms and limitations. The timing and amount of the repurchase transactions under this program will depend on a variety of factors, including market conditions and corporate and regulatory considerations. Depending upon results of operations, market conditions and the development of the economy, as well as other factors, generally we will consider share repurchases on an opportunistic basis from time to time.

During the nine months ended September 30, 2024, 337,070 shares were redeemed by the Company under this buyback program for a total consideration of $100.0 million.

On October 22, 2024, the Company's Board of Directors authorized an additional buyback program of up to $250.0 million of the outstanding ordinary shares of the Company. Along with unutilized amounts under the authorization of February 20, 2024, this permits the Company to repurchase up to $650.0 million worth of ordinary shares.
16. Business Segment and Geographical Information

The Company is a CRO providing outsourced services on a global basis to pharmaceutical, biotechnology, medical device and government and public health organizations. It specializes in the strategic development, management and analysis of programs that support all stages of the clinical development process - from compound selection to Phase I-IV clinical studies. The Company has the expertise and capability to conduct clinical trials in the major therapeutic areas on a global basis and has the operational flexibility to provide development services on a stand-alone basis or as part of an integrated "full-service" solution. The Company has expanded through internal growth, together with a number of strategic acquisitions to enhance its expertise and capabilities in certain areas of the clinical development process.

The Company determines and presents operating segments based on the information that is internally provided to the chief operating decision maker, the (‘CODM’) in accordance with ASC 280, Segment Reporting. The Company determined that the CODM was comprised of the Chief Executive Officer and the Chief Financial Officer.

The Company operates as one reportable segment, which is the provision of outsourced development services on a global basis to pharmaceutical, biotechnology, medical device and government and public health organizations.

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

25

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

ICON Ireland remunerates other operating entities in the Group on the basis of an arm’s length return for the services they perform in each of their local territories. The arm’s length return for each ICON entity is established to ensure that each of ICON Ireland and the ICON entities that are involved in the conduct of services for customers, earn an appropriate return having regard to the assets owned, risks borne, and functions performed by each entity from these intercompany transactions. The arm’s length return is reviewed annually to ensure that it is market appropriate.

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

The geographical distribution of the Company’s segment measures for the three and nine months ended September 30, 2024 and September 30, 2023 and as at September 30, 2024 and December 31, 2023 is as follows:

Overview

We are a CRO providing outsourced development services on a global basis to pharmaceutical, biotechnology, medical device and government and public health organizations. We specialize in the strategic development, management and analysis of programs that support all stages of the clinical development process - from compound selection to Phase I-IV clinical studies. Our vision is to be the healthcare intelligence partner of choice by delivering industry leading solutions and best in class performance in clinical development.

We believe that we are one of a select group of CROs with the expertise and capability to conduct clinical trials in the major therapeutic areas on a global basis and have the operational flexibility to provide development services on a stand-alone basis or as part of an integrated “full service” solution. At September 30, 2024, we employed approximately 42,250 employees in 106 locations in 55 countries. During the three months ended September 30, 2024 we derived 37.2%, 51.1% and 11.7% of our revenue in the United States, Europe and Rest of World respectively (during the period ended September 30, 2023: 40.5%, 47.7% and 11.8% respectively).

Revenue consists of fees earned under contracts with third-party clients. In most cases, a portion of the contract fee is paid at the time the study or trial is started, with the balance of the contract fee generally payable in installments over the study or trial duration, based on the delivery of certain performance targets or milestones. Revenue from long term contracts is recognized on a proportional performance method based on the relationship between cost incurred and the total estimated costs of the trial or on a fee-for-service basis according to the particular circumstances of the contract. As is customary in the CRO industry, we contract with third party investigators in connection with clinical trials. Investigator costs and certain other third party costs are included in our assessment of progress towards completion and costs incurred in measuring revenue. Where these costs are reimbursed by clients, they are included in the total contract value recognized over time, based on our assessment of progress towards completion.    

As the nature of our business involves the management of projects, the majority of which have a duration of one to four years, the commencement or completion of projects in a fiscal year can have a material impact on revenues earned with the relevant clients in such years. In addition, as we typically work with some, but not all, divisions of a client, fluctuations in the number and status of available projects within such divisions can also have a material impact on revenues earned from clients from year to year.

Termination or delay in the performance of an individual contract may occur for various reasons, including, but not limited to, unexpected or undesired results, production problems resulting in shortages of the drug, adverse patient reactions to the drug, the client’s decision to de-emphasize a particular trial or inadequate patient enrollment or investigator recruitment. In the event of termination, the Company is usually entitled to all sums owed for work performed through the notice of termination and certain costs associated with the termination of the study. In addition, contracts generally contain provisions for renegotiation in the event of changes in the scope, nature, duration, or volume of services of the contract.

Our unsatisfied performance obligation comprises our assessment of contracted revenue yet to be earned from projects awarded by clients. At September 30, 2024 we had unsatisfied performance obligations of approximately $15.5 billion (see note 4 - Accounts receivable, unbilled revenue (contract assets) and unearned revenue or payments on account (contract liabilities) for further details). We believe that our unsatisfied performance obligations as of any date is not necessarily a meaningful predictor of future results, due to the potential for cancellation or delay of the projects included in the unsatisfied performance obligation, and no assurances can be given on the extent to which we will be able to realize the unsatisfied performance obligation.

Although we are domiciled in Ireland, we report our results in U.S. dollars. As a consequence, the results of our non-U.S. based operations, when translated into U.S. dollars, could be materially affected by fluctuations in exchange rates between the U.S. dollar and the currencies of those operations.

28

In addition to translation exposures, we are also subject to transaction exposures where the currency in which contracts are priced can be different from the currencies in which costs relating to those contracts are incurred. Our operations in the United States are not materially exposed to such currency differences as the majority of our revenues and costs are in U.S. dollars. However, outside of the United States the multinational nature of our activities means that contracts are usually priced in a single currency, most often U.S. dollars or euro, while costs arise in a number of currencies, depending, among other things, on which of our offices provide staff for the contract and the location of investigator sites. Although many such contracts benefit from some degree of natural hedging, due to the matching of contract revenues and costs in the same currency, where costs are incurred in currencies other than those in which contracts are priced, fluctuations in the relative value of those currencies could have a material effect on our results of operations. We regularly review our currency exposures.

As we conduct operations on a global basis, our effective tax rate has depended, and will depend, on the geographic distribution of our revenue and earnings among locations with varying tax rates. Our results therefore may be affected by changes in the tax rates of the various jurisdictions. In particular, as the geographic mix of our results of operations among various tax jurisdictions changes, our effective tax rate may vary significantly from period to period.

Liquidity and capital resources

The CRO industry is generally not capital intensive. The Company’s principal operating cash needs are payment of salaries, office rents, travel expenditures and payments to investigators. Investing activities primarily reflect capital expenditures for facilities and information systems enhancements, the purchase and sale of short term investments and acquisitions. Financing activities primarily reflects the servicing of the Company's external debt and transactions pertaining to its ordinary shares.

Our clinical research and development contracts are generally fixed price with some variable components and range in duration from a few weeks to several years. Revenue from contracts is generally recognized as income on the basis of the relationship between time incurred and the total estimated contract duration or on a fee-for-service basis. The cash flow from contracts typically consists of a down payment at the time the contract is entered into, with the balance paid in installments over the contract's duration, in some cases on the achievement of certain milestones. Therefore, cash receipts do not correspond to costs incurred and revenue recognized on contracts.

Cash flows

Net cash from operating activities

Net cash provided by operating activities increased by $227.4 million to $948.3 million for the nine months ended September 30, 2024 as compared to net cash provided by operating activities of $720.9 million for the nine months ended September 30, 2023. The increase in net cash provided by operating activities of $227.4 million is primarily due to an increase in underlying operating activity.

The change in working capital is primarily attributable to a decrease in accounts receivable of $491.9 million, an increase in unbilled revenue of $437.9 million and a decrease in unearned revenue of $231.2 million. These changes result from differences in timing of revenue recognition, cash collection and billing on clinical trials. The number of days’ revenue outstanding at September 30, 2024 was 52 days (June 30, 2024: 51 days, March 31, 2024: 49 days, December 31, 2023: 47 days, September 30, 2023: 49 days, June 30, 2023: 52 days). A decrease in the number of days’ revenue outstanding during a period will result in cash inflows to the Company while an increase in days revenue outstanding will lead to cash outflows.

Cash generated from working capital and days’ revenue outstanding may be positively or negatively impacted by, amongst others, the scheduling of contractual milestones over a study or trial duration, the achievement of a particular milestone during the period, the timing of receipt of invoices from third parties for reimbursable costs and the timing of cash receipts from customers. Contract fees are generally payable in installments based on the achievement of certain performance targets or “milestones” (e.g. target patient enrollment rates, clinical testing sites initiated or case report forms completed), such milestones being specific to the terms of each individual contract, while revenues on contracts are recognized as contractual obligations are performed. Further, credit terms negotiated between the Company and its customers also impacts cash inflows and days' revenue outstanding.

Further, the Company repurchased 337,070 ordinary shares for a total consideration of $100.0 million. These outflows were offset by $32.4 million received by the Company from the exercise of equity compensation.

Summarized financial information of issuers and guarantors

In connection with the offering of the New Notes by one of our subsidiaries, ICON Investments Six Designated Activity Company (the "Issuer"), disclosures required by Rule 13-01 (a)(1) through (3) of Regulation S-X are provided below.

The New Notes are guaranteed on a senior secured basis by ICON and its existing and future wholly owned subsidiaries organized in the United States, Ireland and the Grand Duchy of Luxembourg (“Luxembourg”), in each case that guarantee the obligations under our Senior Secured Credit Facilities and the 2026 Notes (the “Subsidiary Guarantors” and, collectively with ICON, the “Guarantors”).

The New Notes are the senior secured obligations of the Issuer and the Guarantors and the New Notes rank equally in right of payment to all of the Issuer’s and Guarantors’ existing and future senior debt (including the Senior Secured Credit Facilities and the 2026 Notes) and senior in right of payment to all of the Issuer’s and Guarantors’ existing and future subordinated debt. The New Notes and the guarantees are secured on a first-lien basis by substantially all of the existing and future assets of the Issuer and the guarantors that also secure the Issuer’s and the guarantors’ obligations under the Senior Secured Credit Facilities and the 2026 Notes on a pari passu basis, subject to permitted liens, and the liens on the collateral securing the New Notes (the “Collateral”) rank equally in priority with the liens on the collateral securing borrowings and guarantees under the Senior Secured Credit Facilities, the 2026 Notes and any other future pari passu first lien indebtedness. The New Notes and the guarantees are effectively senior to any of the Issuer’s and the guarantors’ existing and future unsecured indebtedness to the extent of the value of the assets securing the New Notes and the guarantees. The New Notes and the guarantees are structurally subordinated to all existing and future indebtedness and other liabilities of ICON’s subsidiaries that will not guarantee the New Notes, which includes all of ICON’s subsidiaries organized outside the United States, Ireland and Luxembourg and any other subsidiaries that do not guarantee the Senior Secured Credit Facilities or the 2026 Notes.

The New Notes are, jointly and severally, unconditionally, guaranteed on a senior secured basis by ICON and its existing and future wholly owned subsidiaries organized in a covered jurisdiction that guarantee the obligations under the Senior Secured Credit Facilities and the 2026 Notes. The obligations of each Guarantor under its note guarantee are limited as necessary to prevent the relevant note guarantee from constituting a fraudulent conveyance, fraudulent transfer or unlawful financial assistance under applicable law, or otherwise to reflect limitations under applicable law. By virtue of these limitations, the obligations of a Guarantor under its note guarantee could be significantly less than amounts payable with respect to the notes of any series or a Guarantor may have effectively no obligations under its respective note guarantee. ICON may, at any time, cause a subsidiary to become a Guarantor by executing and delivering a supplemental indenture providing for the Guarantee of payment of the applicable series of notes by such subsidiary on the basis provided in the applicable indenture.

Any Guarantor will be automatically and unconditionally released from all obligations under its note guarantee, and such note guarantee shall thereupon terminate and be discharged and of no further force and effect:

•concurrently with any sale, exchange, disposition or transfer (by merger or otherwise) described in the preliminary prospectus supplement for the offering of New Notes, of any capital stock, or all or substantially all assets of such Guarantor following which such Guarantor is no longer a subsidiary of ICON or ceases to be organized in a covered jurisdiction;
•as to all Guarantors (other than ICON), at the time of any collateral release event;
•upon legal defeasance, covenant defeasance or satisfaction and discharge of the indenture governing the New Notes;
•upon the merger, amalgamation or consolidation of any Guarantor into ICON, the Issuer or another Guarantor or upon the liquidation, dissolution or winding up of such Guarantor;
•the release of such Guarantor from its guarantee under the Senior Secured Credit Facilities (except in the case of a release from the repayment in full of the Senior Secured Credit Facilities); or
•upon such Guarantor becoming an excluded subsidiary.
