Effective January 2022, the board of directors of the Company authorized a $1.8 billion share repurchase program through December 2024, of which $412.5 million remains available for repurchase as of March 31, 2024. In May 2024, the board of directors authorized a new $2.0 billion share repurchase program, effective May 2024 through June 2027. The Company's goals for the share repurchase programs are to offset the dilution created by its employee equity compensation programs over time and provide the flexibility to return capital to shareholders as business and market conditions warrant, while still preserving its ability to pursue other strategic opportunities.

During the three months ended March 31, 2024, the Company repurchased 1.1 million shares of its common stock for $125.4 million.

Net Income per Share

Mar. 31, 2024

Earnings Per Share Reconciliation [Abstract]

Net Income per Share

Basic net income per share is computed using the weighted average number of common shares outstanding during the applicable period. Diluted net income per share is computed using the weighted average number of common shares outstanding during the period, plus the dilutive effect of potential common stock. Potential common stock consists of shares issuable pursuant to stock awards, convertible senior notes and warrants issued by the Company. The dilutive effect of outstanding awards is reflected in diluted earnings per share by application of the treasury stock method and the dilutive effect of the convertible securities is reflected in diluted earnings per share by application of the if-converted method.

The components used in the computation of basic and diluted net income per share for the three months ended March 31, 2024 and 2023 were as follows (in thousands, except per share data):


	For the Three Months Ended March 31,
	2024		2023
Numerator:
Net income	$	175,418	$	97,106
Denominator:
Shares used for basic net income per share	151,628		155,637
Effect of dilutive securities:

Stock awards	3,724		498
Convertible senior notes	2,114		—
Warrants related to issuance of convertible senior notes	—		—
Shares used for diluted net income per share	157,466		156,135
Basic net income per share	$	1.16	$	0.62
Diluted net income per share	$	1.11	$	0.62

For the three months ended March 31, 2024 and 2023, certain potential outstanding shares from service-based stock awards and warrants were excluded from the computation of diluted net income per share because the effect of including these items was anti-dilutive. Additionally, certain market- and performance-based stock awards were excluded from the computation of diluted net income per share because the underlying market and performance conditions for such stock awards had not been met as of these dates. The number of potentially outstanding shares excluded from the computation of diluted net income per share for the three months ended March 31, 2024 and 2023 were as follows (in thousands):


	For the Three Months Ended March 31,
	2024	2023

Service-based stock awards	4,161	7,867
Market- and performance-based stock awards	1,328	1,580

Warrants related to issuance of convertible senior notes	32,006	21,991
Total shares excluded from computation	37,495	31,438

The following table summarizes further details of the Notes:


Notes	Issuance Date	Maturity Date	Principal Amount (in thousands)		Coupon Interest Rate		Effective Interest Rate
2029 Notes	August 18, 2023	February 15, 2029	$	1,265,000	1.125	%	1.388	%

2025 Notes	May 21, 2018	May 1, 2025	$	1,150,000	0.125	%	0.350	%

The conversion rights of the Notes are as follows:


Notes	Conversion Date	Conversion Rate (1)	Conversion Price per Share (1)
2029 Notes	October 15, 2028	7.9170	$	126.31
2027 Notes	May 1, 2027	8.6073	$	116.18
2025 Notes	January 1, 2025	10.5150	$	95.10

(1) The conversion rate for the Notes is established as a number of shares of the Company's commons stock per $1,000 principal amount of the Notes, that is equivalent to the conversion price per share, subject to adjustments in certain events. Upon the occurrence of certain corporate events the Company will increase the conversion rate for a holder that elects to convert its Notes.

The Notes consisted of the following components as of March 31, 2024 and December 31, 2023 (in thousands):


	2029 Notes		2027 Notes		2025 Notes		Total

	March 31, 2024		December 31, 2023
Deferred costs included in prepaid expenses and other current assets	$	47,764	$	44,383
Deferred costs included in other assets	43,240		42,738
Total deferred costs	$	91,004	$	87,121

Information related to incremental costs to obtain a contract with a customer for the three months ended March 31, 2024 and 2023 were as follows (in thousands):


	For the Three Months Ended March 31,
	2024		2023
Amortization expense related to deferred costs	$	14,363	$	12,175
Incremental costs capitalized	19,342		12,417

Amortization expense related to deferred costs is primarily included in sales and marketing expense in the interim condensed consolidated statements of income.

Revenue from Contracts with Customers

The Company sells its services through a sales force located both domestically and internationally. Revenue derived from operations outside of the U.S. is determined based on the country in which the sale originated. Other than the U.S., no single country accounted for 10% or more of the Company’s total revenue for any reported period. Revenue by geography included in the Company’s interim condensed consolidated statements of income for the three months ended March 31, 2024 and 2023 was as follows (in thousands):


	For the Three Months Ended March 31,
	2024		2023
U.S.	$	512,347	$	473,833
International	474,623		441,865
Total revenue	$	986,970	$	915,698

The Company reports its revenue in three solution categories: security, delivery and compute. Security includes solutions that are designed to protect business online by keeping infrastructure, websites, applications and users safe. Delivery includes solutions that are designed to enable business online, including media delivery and web performance. Compute includes cloud computing, edge applications, cloud optimization and storage. Revenue by solution category included in the Company’s interim condensed consolidated statements of income for the three months ended March 31, 2024 and 2023 was as follows (in thousands):


	For the Three Months Ended March 31,
	2024		2023
Security	$	490,681	$	405,552
Delivery	351,758		394,384
Compute	144,531		115,762
Total revenue	$	986,970	$	915,698

Most security, delivery and compute services represent obligations that are satisfied over time as the customer simultaneously receives and consumes the services provided by the Company. Accordingly, the majority of the Company's revenue is recognized over time, generally ratably over the term of the arrangement due to consistent monthly usage commitments that expire each period. Any usage over a given commitment is recognized in the period in which the units are served. A small percentage of the Company's contracts are satisfied at a point in time, such as one-time professional services contracts, integration services and most license sales where the primary obligation is delivery of the license at the start of the term. In these cases, revenue is recognized at a point in time of delivery or satisfaction of the performance obligation.

During the three months ended March 31, 2024 and 2023, the Company recognized $60.5 million and $57.5 million of revenue that was included in deferred revenue as of December 31, 2023 and 2022, respectively.

As of March 31, 2024, the aggregate amount of remaining performance obligations from contracts with customers was $3.4 billion. The Company expects to recognize approximately 65% of its remaining performance obligations as revenue over the next 12 months. The majority of the remaining balance is expected to be recognized over the next two to three years. Remaining performance obligations represent the amount of the transaction price under contracts with customers that are attributable to performance obligations that are unsatisfied or partially satisfied at the reporting date. This consists of future committed revenue for monthly, quarterly or annual periods within current contracts with customers, as well as deferred revenue arising from consideration invoiced in prior periods for which the related performance obligations have not been satisfied. It excludes estimates of variable consideration, such as usage-based contracts with no committed contract, as well as anticipated renewed contracts. Revenue recognized during the three months ended March 31, 2024 and 2023, related to performance obligations satisfied in previous periods was not material.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Debt Disclosure [Abstract]

Debt

Convertible Senior Notes

The Company has three convertible senior notes ("2029 Notes", "2027 Notes" and "2025 Notes") outstanding with a par value totaling $3,565.0 million (collectively, the "Notes") that are senior unsecured obligations of the Company and bear interest payable semi-annually in arrears. The following table summarizes further details of the Notes:


Notes	Issuance Date	Maturity Date	Principal Amount (in thousands)		Coupon Interest Rate		Effective Interest Rate
2029 Notes	August 18, 2023	February 15, 2029	$	1,265,000	1.125	%	1.388	%
2027 Notes	August 16, 2019	September 1, 2027	$	1,150,000	0.375	%	0.539	%
2025 Notes	May 21, 2018	May 1, 2025	$	1,150,000	0.125	%	0.350	%

Conversion Rights of the Notes

At their option, holders may exercise the conversion right of the respective Notes at the following specified times and rates to receive the principal amount in cash and receive any amount in excess of the principal amount in cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election.

Prior to the close of business on the business day immediately preceding the conversion date, as noted in the table below, under the following circumstances a holder may exercise their conversion right:

•during any calendar quarter commencing after the calendar quarter ended December 31, 2023 for the 2029 Notes, December 31, 2019 for the 2027 Notes and June 30, 2018 for the 2025 Notes (and only during such calendar quarter), if the last reported sale price of the Company's common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

•during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of the respective Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company's common stock and the conversion rate on each such trading day; or

•upon the occurrence of specified corporate events.

On or after the respective conversion date, as noted in the table below, holders may convert all or any portion of their respective Notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date.

If the Company undergoes a fundamental change at any time prior to the maturity date, holders of the Notes will have the right, at their option, to require the Company to repurchase for cash all or any portion of their Notes at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest up to, but excluding, the fundamental change repurchase date.

The conversion rights of the Notes are as follows:


Notes	Conversion Date	Conversion Rate (1)	Conversion Price per Share (1)
2029 Notes	October 15, 2028	7.9170	$	126.31
2027 Notes	May 1, 2027	8.6073	$	116.18
2025 Notes	January 1, 2025	10.5150	$	95.10

Components and Fair Value of the Notes

The Notes consisted of the following components as of March 31, 2024 and December 31, 2023 (in thousands):


	2029 Notes		2027 Notes		2025 Notes		Total
As of March 31, 2024

Estimated fair value (1)	$	1,376,915	$	1,289,219	$	1,467,274	$	4,133,408

Note Hedges and Warrants

To minimize the impact of potential dilution upon conversion of the Notes, the Company entered into convertible note hedge transactions with respect to its common stock concurrently with each respective note issuance month. The note hedge transactions cover an approximate number of shares of the Company’s common stock at a strike price that corresponds to the conversion prices for the Notes, also subject to adjustment, and are exercisable upon conversion of the Notes. The note hedge transactions expire upon the respective maturity dates of the Notes. The Company determined that the note hedges meet the definition of a derivative and are classified in stockholders’ equity, as the note hedges are indexed to the Company's common stock, and the Company, at its election, may receive cash, shares of the Company's common stock or a combination of cash and shares of the Company's common stock. The Company recorded the purchase of the hedges as a decrease to additional paid-in capital. The Company does not recognize subsequent changes in fair value of the note hedges in its interim condensed consolidated financial statements.

Separately, the Company also entered into warrant transactions concurrently with each of the note issuances, whereby the Company sold warrants to acquire, subject to anti-dilution adjustments, shares of the Company’s common stock at a predetermined strike price per share. The convertible note hedge and warrant transactions will generally have the effect of increasing the conversion price of each of the Notes to the respective strike price related to the warrant transactions. The Company determined that the warrants meet the definition of a derivative and are classified in stockholders’ equity, as the warrants are indexed to the Company's common stock, and the Company, at its election, may pay or deliver to holders cash or shares of the Company's common stock. The Company recorded the proceeds from the issuance of the warrants as an increase to additional paid-in capital. The Company does not recognize subsequent changes in fair value of the warrants in its interim condensed consolidated financial statements. The following table summarizes the main terms impacting the note hedges and warrants (in thousands, except per share data):


	2029 Notes		2027 Notes		2025 Notes
Note hedge transaction cost	$	236,555	$	312,225	$	261,740
Shares covered by note hedge transactions	10,015		9,898		12,093
Shares related to warrant transactions	10,015		9,898		12,093
Strike price per share related to warrant transactions	$	180.44	$	178.74	$	149.18
Aggregate proceeds from sale of warrants	$	90,195	$	185,150	$	119,945

Revolving Credit Facility

In November 2022, the Company entered into a $500.0 million five-year, revolving credit agreement (the “2022 Credit Agreement”). Borrowings under the 2022 Credit Agreement may be used to finance working capital needs and for general corporate purposes. The 2022 Credit Agreement provides for an initial $500.0 million in revolving loans. Under specified circumstances, the facility can be increased to up to $1.0 billion in aggregate principal amount. The 2022 Credit Agreement expires on November, 22, 2027, and any amounts outstanding thereunder will become due and payable, subject to up to two one-year extensions at the Company's request and with the consent of the lenders party thereto.

Borrowings under the 2022 Credit Agreement bear interest, at the Company's option, and subject to a credit spread adjustment, at a term benchmark rate plus a spread of 0.75% to 1.125%, a reference rate plus a spread of 0.75% to 1.125%, or a base rate plus a spread of 0.00% to 0.125%, in each case with such spread being determined based on the Company's consolidated leverage ratio specified in the 2022 Credit Agreement. Regardless of what amounts, if any, are outstanding under the 2022 Credit Agreement, the Company is also obligated to pay an ongoing commitment fee on undrawn amounts at a rate of 0.07% to 0.125%, with such rate being based on the Company's consolidated leverage ratio specified in the 2022 Credit Agreement.

The 2022 Credit Agreement contains customary representations and warranties, affirmative and negative covenants and events of default. As of March 31, 2024, the Company was in compliance with all covenants. The negative covenants include restrictions on subsidiary indebtedness, liens and fundamental changes. These covenants are subject to a number of important exceptions and qualifications. The principal financial covenant requires a maximum consolidated leverage ratio. There were no outstanding borrowings under the 2022 Credit Agreement as of March 31, 2024.

Interest Expense

The Notes bear interest at fixed rates that are payable semi-annually in arrears on their respective interest payment dates each year. Interest expense, together with ongoing commitment fees under the terms of the Company's credit agreements, included in the interim condensed consolidated statements of income for the three months ended March 31, 2024 and 2023 was as follows (in thousands):

Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2024
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's effective income tax rate is based on estimated income for the year, the estimated composition of the income in different jurisdictions and discrete adjustments, if any, in the applicable quarterly periods. Potential discrete adjustments include tax charges or benefits related to stock-based compensation, changes in tax legislation, settlements of tax audits or assessments, uncertain tax positions and acquisitions, among other items. The Company’s effective income tax rate was 6.8% and 23.5% for the three months ended March 31, 2024 and 2023, respectively. The lower effective tax rate for the three months ended March 31, 2024 was primarily due to an increase in the excess tax benefit related to stock-based compensation, a decrease in tax on global intangible low-taxed income and a decrease in the valuation allowance recorded against state and foreign credits. These amounts were partially offset by a decrease in foreign income taxed at lower rates and the impact of the enactment of a 15% global minimum corporate income tax that the Organisation for Economic Co-operation and Development ("OECD") and OECD member countries have begun implementing and which impacted the Company beginning January 1, 2024. For the three months ended March 31, 2024, the effective income tax rate was lower than the federal statutory tax rate due to the excess tax benefit related to stock-based compensation, foreign income taxed at lower rates and the benefit of U.S. federal, state and foreign research and development credits. These amounts were partially offset by non-deductible stock-based compensation and the 15% global minimum corporate income tax. For the three months ended March 31, 2023, the effective income tax rate was higher than the federal statutory tax rate due to tax on global intangible low-taxed income, non-deductible stock-based compensation, a shortfall related to stock-based compensation and an increase in the valuation allowance recorded against tax credits and foreign net operating losses. These amounts were partially offset by foreign income taxed at lower rates and the benefit of U.S. federal, state and foreign research and development credits.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

The Company offers certain eligible employees the ability to participate in a non-qualified deferred compensation plan. The mutual funds held by the Company that are associated with this plan are classified as restricted equity securities. Additionally, the Company holds certain money market funds that are classified as equity securities. These securities are not included in the available-for-sale securities table above but are included in marketable securities in the interim condensed consolidated balance sheets.

Unrealized gains and unrealized temporary losses on investments classified as available-for-sale are included within accumulated other comprehensive loss in the interim condensed consolidated balance sheets. Upon realization, those amounts are reclassified from accumulated other comprehensive loss to interest and marketable securities income, net in the interim condensed consolidated statements of income. As of March 31, 2024, the Company held for investment corporate bonds and U.S. government agency obligations with a fair value of $179.9 million, which are classified as available-for-sale marketable securities and have been in a continuous unrealized loss position for more than 12 months. The unrealized losses related to these securities were $2.6 million and are included in accumulated other comprehensive loss as of March 31, 2024. The unrealized losses are attributable to changes in interest rates. Based on the evaluation of available evidence, the Company does not believe any unrealized losses represent other than temporary impairments.

The fair value measurements within the fair value hierarchy of the Company’s financial assets as of March 31, 2024 and December 31, 2023 were as follows (in thousands):

As of March 31, 2024 and December 31, 2023, the Company grouped money market funds and mutual funds using a Level 1 valuation because market prices for such investments are readily available in active markets. As of March 31, 2024 and December 31, 2023, the Company grouped time deposits, commercial paper, corporate bonds and U.S. government agency obligations using a Level 2 valuation because quoted prices for similar assets in active markets (or identical assets in an inactive market) are available. The Company did not have any transfers of assets or liabilities between Level 1 or Level 2 of the fair value measurement hierarchy during the three months ended March 31, 2024.

When developing fair value estimates, the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs. When available, the Company uses quoted market prices to measure fair value. The valuation technique used to measure fair value for the Company's Level 1 and Level 2 assets is a market approach, using prices and other relevant information generated by market transactions involving identical or comparable assets. If market prices are not available, the fair value measurement is based on models that use primarily market-based parameters including yield curves, volatilities, credit ratings and currency rates. In certain cases where market rate assumptions are not available, the Company is required to make judgments about the assumptions market participants would use to estimate the fair value of a financial instrument.

Contractual maturities of the Company’s available-for-sale marketable securities held as of March 31, 2024 and December 31, 2023 were as follows (in thousands):

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring During the first quarter of 2023, management committed to an action to restructure certain parts of the Company to enable it to prioritize investments in the fastest growing areas of the business. As a result, certain headcount reductions were necessary. The Company has incurred $20.7 million related to this action through March 31, 2024. During the three months ended March 31, 2023, $23.6 million was incurred related to this action. There were no material charges incurred during the three months ended March 31, 2024, and the Company does not expect to incur material additional charges related to this action. The Company launched its FlexBase program in May 2022, which is a flexible workspace arrangement that allows employees to choose to work from their home office, a Company office or a combination of both, which is a significant change to the way employees worked prior to the program. The Company began to identify certain facilities that were no longer needed in the fourth quarter of 2021. As a result, impairments of right-of-use assets and leasehold improvements were recognized. The Company has incurred $35.9 million of restructuring charges related to this action, of which $0.9 million and $18.5 million were incurred during the three months ended March 31, 2024 and 2023, respectively. As the Company continues to execute its FlexBase program, additional charges related to this action are expected to occur through the first half of 2024, however, the Company does not expect to incur any material additional restructuring charges related to this action. The Company also recognizes restructuring charges for redundant employees, facilities and contracts associated with completed acquisitions.

Nature of Business and Basis of Presentation	Nature of Business and Basis of Presentation Akamai Technologies, Inc. (the “Company”) provides solutions to power and protect life online. Its massively distributed edge and cloud platform, or Akamai Connected Cloud, comprises more than 4,100 edge points-of-presence in approximately 130 countries and nearly 750 cities. The Company was incorporated in Delaware in 1998 and is headquartered in Cambridge, Massachusetts. The Company is currently organized and operates as one operating and reportable segment. The accompanying interim condensed consolidated financial statements are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information. These financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation in the accompanying interim condensed consolidated financial statements. Certain information and footnote disclosures normally included in the Company’s annual audited consolidated financial statements and accompanying notes have been condensed in, or omitted from, these interim financial statements. Accordingly, the unaudited interim condensed consolidated financial statements included herein should be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company’s annual report on Form 10-K for the year ended December 31, 2023, filed with the Securities and Exchange Commission on February 28, 2024. The December 31, 2023 condensed consolidated balance sheet included herein is derived from the Company's audited consolidated financial statements. The results of operations presented in this quarterly report on Form 10-Q are not necessarily indicative of the results of operations that may be expected for any future periods. In the opinion of management, these unaudited interim condensed consolidated financial statements include all adjustments, consisting only of normal recurring adjustments, that are necessary for a fair statement of the results of all interim periods reported herein. Recent Accounting Pronouncements In December 2023, the Financial Accounting Standards Board ("FASB") issued guidance to improve income tax disclosures, primarily through enhanced disclosures for the rate reconciliation and income taxes paid, in addition to the modification or elimination of other disclosures. This guidance will be effective for the Company's annual period ending December 31, 2025 and is to be applied prospectively with the option to adopt retrospectively. The Company is evaluating the impact the update will have on its disclosures. In November 2023, the FASB issued guidance to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expense and application of all segment disclosure requirements to entities with a single reportable segment. This guidance will be effective for the Company's annual period ending December 31, 2024 and interim periods beginning on January 1, 2025 and is to be applied retrospectively. The Company is evaluating the impact the update will have on its disclosures.
