Rewritten

In addition to the effects of the global economic and geopolitical climate on our business and operations (including as a result of U.S. [added: budget cuts,] tariffs, trade barriers and restrictions) discussed in Item 7 of this Form 10-K and in the risk factors below, additional or unforeseen effects from the global economic and geopolitical climate may give rise to or amplify many of these risks discussed below.

Rewritten

*We may not be able to maintain the quality of our existing products and services.* We operate in a rapidly evolving market, and our success depends on our ability to deliver high quality and timely [removed: research and analysis] [added: insights] to our clients.

Rewritten

Any failure to continue to provide credible and reliable information and [removed: insight] [added: insights] that [removed: is] [added: are] useful to our clients could have a material adverse effect on future business and operating results.

Rewritten

Further, if our published data, opinions or viewpoints are considered to be wrong, lack independence, or are not substantiated by appropriate research, our reputation will suffer and demand for our products and [added: services may decline.]

Rewritten

[removed: Additionally, significant] delays in new product or service releases or significant problems in creating new products or services could materially adversely affect our business, results of operations and financial position.

Rewritten

Our future success will depend upon our ability to develop and introduce in a timely manner new [added: offerings,] or [removed: enhance] [added: enhancements to] existing [removed: offerings] [added: offerings,] that address the changing needs of this constantly evolving marketplace.

Rewritten

In addition, some of our content is exposed to Internet search [removed: engines,] [added: engines and large language models (“LLM”),] which help generate website traffic.

Rewritten

Search engines [added: and LLMs] often update their proprietary algorithms, which affects the placement of links to our websites.

Rewritten

Some search engines [added: and LLMs] also provide substantive content in search results, [added: including AI-generated content,] which, if expanded to the areas in which we operate, could reduce the need to enter our websites.

Rewritten

When a major search engine [added: or LLM] changes its algorithms in a manner that negatively affects our placement in search results or makes it less likely for our target audience to enter our websites, our business, results of operations and financial position may be harmed.

Rewritten

Developing, testing, and deploying AI systems [added: has required, and] will [removed: require] [added: continue to require,] additional investment and [removed: increase our costs.][added: increased costs, including costs related to developing talent to implement AI technologies.]

Rewritten

Although [added: generally contractually] prohibited, clients or others may load our proprietary information into large language models, which could reduce the value of our offerings.

Rewritten

*Our [removed: Research] [added: Insights] business depends on renewals of subscription-based services and sales of [removed: new* *subscription-based] [added: new subscription-based] services for a significant portion of our revenue, and [removed: our* *failure] [added: our failure] to renew at historical rates or generate new sales of such [removed: services* *will] [added: services will] lead to a decrease in our revenues.* A large portion of our success depends on our ability to generate renewals of our subscription-based [removed: research] [added: insights] products and services and new sales of such products and services, both to new clients and existing clients.

Rewritten

These products and services constituted approximately [removed: 77%] [added: 78%] and [removed: 76%] [added: 77%] of total revenues from our operations for [removed: 2024] [added: 2025] and [removed: 2023,][added: 2024, respectively.]

Rewritten

Our [removed: research] [added: Insights] subscription contracts are typically for twelve months or longer.

Rewritten

While our [removed: Research] [added: Insights] client retention rate was [added: 85% and] 84% for [removed: both 2024] [added: 2025] and [removed: 2023,] [added: 2024, respectively,] there can be no guarantee that we will continue to maintain this rate of client renewals.

Rewritten

Our insurance coverage for [removed: 2024] [added: 2025] (and likely beyond) excludes coverage for cancellations due to communicable diseases.

Rewritten

*Our Consulting business depends on non-recurring engagements and our failure to secure new* *engagements could lead to a decrease in our revenues.* Consulting segment revenues constituted approximately 9% of total revenues from our on-going operations in both [removed: 2024] [added: 2025] and [removed: 2023.][added: 2024.]

Rewritten

*We may not be able to attract and retain qualified personnel which [removed: could* *jeopardize] [added: could jeopardize] the quality of our products and services and our future growth plans.* Our success is based on attracting and retaining talented employees and we depend heavily upon the quality of our senior management, research analysts, consultants, sales and other key personnel.

Rewritten

Our employee hiring and retention also depend on our brand and reputation as well as our ability to build and maintain an inclusive workplace culture that enables [removed: our employees to thrive.]

Rewritten

Additionally, the laws [added: (including evolving] and [added: uncertain copyright law as it applies to the training, use, developments, and deployment of AI) and] enforcement mechanisms to protect our intellectual property from unauthorized use in new technologies like AI and machine learning [removed: are evolving and] may be inadequate.

Rewritten

The cybersecurity risks we face range from cyber attacks common to most industries, such as the development and deployment of malicious software to gain access to our networks and attempt to steal confidential information, launch distributed denial of service attacks, or attempt [removed: other coordinated disruptions, to more advanced threats that target us because of our prominence in the global research and advisory field.]

Rewritten

Like many multinational corporations, we, and some third parties upon which we rely, have experienced cyber attacks on our computer systems and networks in the past and may experience them in the future, likely with more frequency and [added: sophistication, and involving a broader range of devices and modes of attack, all of which will increase the difficulty of detecting and successfully defending against them.]

Rewritten

We have implemented various security controls [added: designed] to [removed: meet] [added: address] our security [removed: obligations, while also defending] [added: obligations and to defend] against constantly evolving security threats.

Rewritten

Rewritten

Additionally, the security compliance landscape continues to evolve, requiring us to stay apprised of changes in cybersecurity [added: privacy,] and [removed: data privacy laws,] [added: protection laws and] regulations, and security requirements required by our clients, such as the European Union General Data Protection Regulation [removed: (GDPR),] [added: (“GDPR”),] the California Consumer Privacy Act [removed: (CCPA)] [added: (“CCPA”)] and California Privacy Rights Act [removed: (CPRA),] [added: (“CPRA”),] the Brazilian General Data Protection Law [removed: (LGPD),] [added: (“LGPD”),] the Chinese Cybersecurity, Data Security and Personal Information Protection laws (and other new and proposed data protection [removed: laws),] [added: laws) and certain standards of the] International Organization for Standardization [removed: (ISO),] [added: (“ISO”),] and National Institute of Standards and Technology [removed: (NIST).][added: (“NIST”).]

Rewritten

A cyber attack, widespread internet failure or internet access limitations, or disruption of our critical information technology systems [added: (or those of our service providers)] through denial of service, viruses, or other events could cause delays in initiating or completing sales, impede delivery of our products and services to our clients, disrupt other critical client-facing or business processes or dislocate our critical internal functions.

Rewritten

Additionally, any [added: actual or perceived] material [added: security] breaches [removed: of cybersecurity] or [added: incidents or] other technology-related [removed: catastrophe,] [added: catastrophes,] or media reports of perceived security vulnerabilities to our systems or those of our third parties, even if no [removed: breach] [added: breach, incident or catastrophe] has been attempted or occurred, could cause us to experience reputational harm, loss of customers and revenue, fines, regulatory actions and scrutiny, sanctions or other statutory penalties, litigation, liability for failure to safeguard our customers’ information, or financial losses that are either not insured against or not fully covered through any insurance maintained by us.

Rewritten

[removed: The risks involved in each acquisition or investment include the possibility of paying more than the] value we derive from the acquisition, dilution of the interests of our current stockholders should we issue stock in the acquisition, decreased working capital, increased indebtedness, the assumption of undisclosed liabilities and unknown and unforeseen risks, the ability to retain key personnel of the acquired company, the inability to complete the transaction due to regulatory review, the inability to integrate the business of the acquired company, increase revenue or fully realize anticipated synergies, the time to train the sales force to market and sell the products of the acquired business, the potential disruption of our ongoing business and the distraction of management from our day to day business.

Rewritten

Our dispositions involve additional risks and uncertainties, such as ability to sell such businesses on satisfactory price and terms and in a timely manner, or at all, disruption to other parts of the businesses and distraction of management, allocation of internal resources that would otherwise be devoted to completing [added: strategic acquisitions, loss of key employees or customers, and exposure to unanticipated liabilities or ongoing obligations to support the businesses following such dispositions, and other adverse financial impacts.]

Rewritten

[removed: *Our sales to governments are subject to appropriations, complex compliance requirements and some may be terminated early.*] We derive significant revenues from [removed: research] [added: insights] and consulting contracts with the United States government and its respective agencies, numerous state and local governments and their respective agencies, and foreign governments and their agencies.

Rewritten

[added: The outstanding debt may limit the] amount of cash or additional credit available to us, which could restrain our ability to expand or enhance products and services, respond to competitive pressures or pursue future business opportunities requiring substantial investments of additional capital.

Rewritten

In addition, acts of civil unrest, failure of critical infrastructure, terrorism, war and armed [removed: conflict (including the ongoing conflicts in the Middle East, Ukraine and Russia),] [added: conflict,] and abrupt political change, as well as responses by various governments and the international community to such acts, can have a negative effect on our business.

Rewritten

Recent Developments

New in FY2025

Our Insights contract value with the US federal government was approximately $126.0 million at December 31, 2025.

New in FY2025

Less than half of our December 31, 2024 Insights contract value was retained in 2025.

New in FY2025

In addition to the non-renewals, we have received notices of termination-for-convenience from various US government agencies for approximately $3.0 million of contracts that are primarily scheduled to expire in the first quarter of 2026.

New in FY2025

As the current geopolitical environment remains unpredictable, we continue to monitor and evaluate the impact, both direct and indirect, of government actions that could adversely impact our business operations and financial performance.

New in FY2025

On July 4, 2025, the One Big Beautiful Bill Act (the “OBBBA”) was enacted in the U.S. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions.

New in FY2025

The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027.

New in FY2025

OBBBA did not have a material impact on our consolidated financial results in the current period.

New in FY2025

We are currently assessing and will continue to assess and reflect the impact of OBBBA on our future consolidated financial statements as appropriate.

New in FY2025

Our most recent annual impairment test of goodwill was a quantitative analysis conducted during the quarter ended September 30, 2025 that indicated an impairment of the Company's Digital Markets reporting unit.

New in FY2025

During the three months ended September 30, 2025, ongoing weakness in the market as well as changes in our internal organization structure prompted a revision to the long-term earnings forecast for the Digital Markets business.

New in FY2025

During the year ended December 31, 2025, a goodwill impairment loss of $150.0 million was recognized in the Digital Markets reporting unit.

New in FY2025

The fair value of that reporting unit was estimated using a combination of the expected present value of future cash flows and market approach.

New in FY2025

On January 29, 2026, we entered into a definitive agreement to sell our Digital Markets business.

New in FY2025

As of December 31, 2025, the assets and liabilities of Digital Markets were considered held for sale, resulting in $106.4 million of assets held for sale and $20.5 million of liabilities held for sale on the Consolidated Balance Sheet.

New in FY2025

The majority of the held for sale assets were goodwill, property, equipment and leasehold improvements, net and accounts receivable, with carrying amounts of $49.1 million, $26.3 million and $25.2 million, respectively, while the majority of the held for sale liabilities was accounts payable and accrued liabilities, with a carrying amount of $14.2 million.

New in FY2025

On February 5, 2026, we completed the sale of Digital Markets for approximately $110.0 million, prior to customary purchase price adjustments.

New in FY2025

The decrease in 2025 is primarily due to the goodwill impairment loss in 2025, the gain on event cancellation insurance claims in 2024 and an increase in the provision for income taxes.

New in FY2025

When a subscription contract is invoiced, we record the billable amount as a fee receivable, representing our legally enforceable right to payment.

New in FY2025

The corresponding amount is recognized as deferred revenue until the underlying services are provided and control is transferred to the customer.

New in FY2025

In certain instances, we may have satisfied our performance obligations and earned revenue prior to invoicing the customer.

New in FY2025

In such cases, we record an unbilled receivable, which represents our right to payment for services already delivered but not yet billed.

New in FY2025

Goodwill and other intangible assets — Our goodwill is evaluated in accordance with FASB ASC Topic 350, which requires goodwill to be assessed for impairment at least annually and whenever events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable.

New in FY2025

In addition, an impairment evaluation of our amortizable intangible assets may also be performed if events or circumstances indicate potential impairment.

New in FY2025

Among the factors that could trigger an impairment review are current operating results that do not align with our annual plan or historical performance; changes in our strategic plans or the use of our assets; restructuring charges or other changes in our business segments; competitive pressures and changes in the general economy or in the markets in which we operate; and a significant decline in our stock price and our market capitalization relative to our net book value.

New in FY2025

When performing our annual assessment of the recoverability of goodwill, we initially perform a qualitative analysis evaluating whether any events or circumstances occurred or exist that provide evidence that it is more likely than not that the fair value of any of our reporting units is less than the related carrying amount.

New in FY2025

If we do not believe that it is more likely than not that the fair value of any of our reporting units is less than the related carrying amount, then no quantitative impairment test is performed.

New in FY2025

However, if the results of our qualitative assessment indicate that it is more likely than not that the fair value of a reporting unit is less than its respective carrying amount, then we perform a quantitative impairment test.

New in FY2025

Evaluating the recoverability of goodwill requires judgments and assumptions regarding future trends and events.

New in FY2025

As a result, both the precision and reliability of our estimates are subject to uncertainty.

New in FY2025

Among the factors that we consider in our qualitative assessment are general economic conditions and the competitive environment; actual and projected reporting unit financial performance; forward-looking business measurements; and external market assessments.

New in FY2025

To determine the fair values of our reporting units for a quantitative analysis, we typically utilize detailed financial projections, which include significant variables, such as projected rates of revenue growth, profitability and cash flows, as well as assumptions regarding discount rates, our weighted average cost of capital and other data.

New in FY2025

Our most recent annual impairment test of goodwill was a quantitative analysis conducted during the quarter ended September 30, 2025 that indicated an impairment of our Digital Markets reporting unit.

New in FY2025

During the three months ended September 30, 2025, ongoing weakness in the market as well as changes in our internal organization structure prompted a revision to the long-term earnings forecast for the Digital Markets business.

New in FY2025

As a result, during the year ended December 31, 2025 a goodwill impairment loss of $150.0 million was recognized in the Digital Markets reporting unit, which is included in Other for segment reporting purposes.

New in FY2025

The fair value of that reporting unit was estimated using a combination of the expected present value of future cash flows and market approach.

New in FY2025

Subsequent to completing our 2025 annual impairment test, no events or changes in circumstances were noted that required an interim goodwill impairment test.

New in FY2025

Note 1 — Business and Significant Accounting Policies and Note 3 — Goodwill and Intangible Assets in the Notes to Consolidated Financial Statements provide additional information regarding our goodwill and amortizable intangible assets.

Dropped from FY2024

On July 25, 2024 the Company entered into a settlement agreement to resolve litigation concerning the Company's event cancellation insurance for 2020 and 2021.

Dropped from FY2024

The settlement resolved all remaining 2020 and 2021 event cancellation insurance claims for $300.0 million.

Dropped from FY2024

Generally, it is our policy to record the amount of a subscription contract that is billable as a fee receivable at the time the contract is signed with a corresponding amount as deferred revenue because the contract represents a legally enforceable claim.

Dropped from FY2024

In December 2024, we completed an intercompany transfer of certain intellectual property (IP).

Dropped from FY2024

As a result, we recorded a deferred tax asset of approximately $163.2 million, based on the fair value of the IP rights transferred.

Dropped from FY2024

The deferred tax asset represents the value of future tax deductions for amortization of the assets in the acquiring jurisdiction.

Dropped from FY2024

The fair value of the intellectual property was determined using an income approach based on unobservable inputs and involves significant judgments such as, but not limited to, future cash flows and discount rates.

Dropped from FY2024

Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates.

We recognized a pre-tax gain of $135.4 million during the year ended December 31, 2023.
