Gartner (IT) 10-K risk factor changes: FY2023 vs FY2022

In addition to the effects of the global economic and geopolitical climate on our business and operations 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 [removed: give rise to or amplify many of these risks discussed below.][added: give*]

Risks in this section are grouped in the following categories: (1) strategic and operational risks; (2) macroeconomic and industry risks; [added: and] (3) legal and regulatory [removed: risks; and (4) risks related to our Common Stock.][added: risks.]

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

Nonetheless, to maintain our competitive position, we must continue to anticipate the needs of our clients, develop, [removed: enhance] [added: enhance, protect,] and improve our existing products, as well as new products and services to address those needs, deliver all products and services in a timely, user-friendly and state of the art manner, and appropriately position and price new products and services relative to the marketplace and our costs of developing them.

*Technology is rapidly evolving, and if we do not continue to develop new product and service offerings in response to these changes, our business could suffer.* Disruptive technologies, including in areas of artificial intelligence [added: (“AI”)] and machine learning, are rapidly changing the environment in which we, our clients, and our competitors operate and could affect the nature of how we generate revenue.

However, we may not be successful in responding to these forces and enhancing our product and service offerings on a timely [removed: basis,] [added: basis or in a cost-efficient manner,] and any enhancements we develop may not adequately address the changing needs of our clients.

These products and services constituted approximately 76% [removed: and 79%] of total revenues from our [removed: on-going] operations for [removed: 2022] [added: both 2023] and [removed: 2021, respectively.][added: 2022.]

- delivering high-quality and timely analysis and [removed: advice] [added: insight] to our clients;

While our Research client retention rate was [removed: 86%] [added: 84% and 86.3%] for [removed: both 2022] [added: 2023] and [removed: 2021,] [added: 2022, respectively,] there can be no guarantee that we will continue to maintain this rate of client renewals.

[added: *The profitability and success of our conferences and other meetings are subject to external factors beyond our control.*] The market for desirable dates and locations for our activities has historically been highly competitive.

Our event cancellation [removed: insurance, including] [added: insurance included] a two-year policy covering destination conferences during 2020 and 2021 and a policy covering Evanta conferences during [removed: 2020, provided up to $170 million in coverage for 2020 cancellations with the right to reinstate the policy limits one time if those limits are utilized.][added: 2020.]

[removed: The] [added: However, the] insurer has contested our right to reinstate the limits and [removed: to] use [added: the] reinstated limits to cover [added: additional] losses resulting from [added: 2020] conferences cancelled due to COVID-19.

Gartner's two-year event cancellation policy also covered events that were planned for 2021 but cancelled, with limits of $150 million with the right to reinstate up to that amount [removed: one time] if the initial limits are [removed: inadequate.][added: inadequate to cover the loss.]

The insurer has contested all coverage for events [removed: cancelled in] [added: that were planned for] 2021 [added: but were cancelled] due to [removed: COVID-19.][added: COVID-19, as well as Gartner’s right to reinstate the policy limits.]

[removed: In 2022, Gartner] [added: We are] also [removed: commenced] [added: the plaintiff in] litigation [removed: against] [added: with] the insurance broker [removed: who] [added: that] negotiated and procured our event cancellation insurance.

[removed: It] [added: Although document discovery in our cases against the insurer and insurance broker] is [removed: difficult to] [added: continuing, we cannot] predict how long it will take to resolve these [removed: lawsuits and] [added: lawsuits, whether we will be successful or] the [added: impact the] resolution could [removed: affect] [added: have on] our financial results.

Our insurance coverage for [removed: 2022] [added: 2023] (and likely beyond) excludes coverage for cancellations due to communicable diseases.

*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: 2022] [added: 2023] and [removed: 2021.][added: 2022.]

[removed: In addition, revenue] from our contract optimization business can fluctuate significantly from period to period and is not predictable.

We face competition for qualified professionals from, among others, technology companies, market research firms, consulting firms, financial services companies and electronic and print media companies, some of which have [added: significant financial resources and] a [removed: greater ability] [added: willingness] to [added: deploy those resources to] attract and compensate these professionals.

We face risks related to global [added: and industry-specific] labor shortages, and competitive markets [removed: have increased] [added: can increase] attrition throughout our sector.

An inability to retain key personnel or to hire and train additional qualified personnel could materially adversely affect the quality of our products and services, as well as our future business and operating [removed: results or stock price.][added: results.]

Despite our efforts to protect our intellectual property rights, [removed: unauthorized] third parties may obtain [removed: and use] [added: unauthorized access to our intellectual property,] technology or other information that we regard as proprietary.

[removed: The] [added: Further, the] laws and enforcement mechanisms of certain countries, particularly in emerging markets, do not protect our proprietary rights to the same extent as the laws of the United States.

Conducting business in certain foreign jurisdictions may require accepting compromised protections or yielding of rights to technology, data or intellectual property [removed: rights] in order to access those markets.

[removed: Our] [added: Additionally, our] employees are subject to restrictive covenant agreements (which include provisions related to employees’ ability to compete and solicit customers and employees) and assignment of invention agreements, to the extent permitted under applicable law.

If a former employee violates the provisions of the restrictive covenant agreement, we seek to enforce the restrictions but there is no assurance that we will be successful in our [removed: efforts.][added: efforts, and enforceability of certain restrictive covenants may decrease significantly]

*Privacy concerns could damage our reputation and deter current and potential clients from using our products and [removed: services or attending our conferences.*] [added: services.*] Concerns relating to global data privacy have the potential to damage our reputation and deter current and prospective clients from using our products and services or attending our conferences.

Any [removed: systems failure] [added: system] or [added: process failure, or] compromise of our security that results in the disclosure of our users’ personal [removed: data] [added: data,] could seriously limit the consumption of our products and services and the attendance at our conferences, as well as harm our reputation and brand and, therefore, our business.

We have implemented various security controls to [removed: both] meet our security obligations, while also defending against constantly evolving security threats.

As a result of [removed: transitioning to] [added: operating in] a [removed: virtual-first hybrid, remote-work] [added: hybrid work] environment, most of our employees are working [removed: remotely,] [added: virtually for a period of time,] which magnifies the importance of the integrity of our remote access security measures.

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

[removed: *We have grown, and may continue to grow, through acquisitions] [added: *Our acquisitions, dispositions,] and strategic* *investments, [removed: which could] involve substantial risks.* We have made and may continue to make acquisitions of, or significant investments in, businesses that offer complementary products and services or otherwise support our growth objectives.

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 [added: complete the transaction due to regulatory review, the inability to] integrate the business of the acquired company, increase revenue or fully realize anticipated synergies, [added: 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.]

In [removed: Arlington,] [added: several locations,] we have consolidated [removed: all] our [removed: businesses into a single building] [added: operations] and [removed: have] sublet substantially all [removed: of] the excess [removed: space in our other properties.][added: space.]

To accommodate our growth going forward, we have moved to a global hoteling model to better manage our footprint and operating expenses, and will secure new space when the opportunities and [removed: need] [added: needs] arise.

At December 31, [removed: 2022] [added: 2023] and [removed: 2021,] [added: 2022,] approximately [removed: $932 million] [added: $1.0 billion] and [removed: $790] [added: $932] million, respectively, of our outstanding revenue contracts were attributable to government entities.

*Our outstanding debt obligations could negatively impact our financial condition and future operating results.* As of December 31, [removed: 2022,] [added: 2023,] the Company had outstanding debt of [removed: $282] [added: $274] million under its 2020 term loan and revolving credit facility (the “2020 Credit Agreement”), $800 million of Senior Notes due 2028 (the “2028 Notes”), $600 million of Senior Notes due 2029 (the “2029 Notes”) and $800 million of Senior Notes due 2030 (the “2030 Notes”).

[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.

In addition, acts of civil unrest, failure of critical infrastructure, terrorism, armed [removed: conflict,] [added: conflict (including in the Middle East),] war (including the war in Ukraine), 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.

*rise to or amplify many of these risks discussed below.

Similarly, some of our content is exposed to the datasets leveraged by AI chatbots, and these chatbots may provide substantive content, either with or without contribution, in query responses to users which could reduce the need to enter our websites.

*Uncertainty in the development, deployment, and use of AI in our platform and products and by our customers and competitors may result in harm to our business and reputation.* We use, and may expand our use of, machine learning and AI technologies in some of our products, services, and processes.

Developing, testing, and deploying AI systems will require additional investment and increase our costs.

If we fail to keep pace with rapidly evolving AI technological developments, our competitive position and business results may be negatively impacted.

Moreover, the development, adoption, and use of generative AI technologies are still in their early stages, and ineffective or inadequate AI development or deployment practices by Gartner or third-party developers or vendors could result in unintended consequences.

For example, AI algorithms that we use may be flawed or may be based on datasets that are biased or insufficient.

Third parties may also be able to use AI to create technology that could reduce demand for our products.

Although prohibited, clients or others may load our proprietary information into large language models, which could reduce the value of our offerings.

In addition, the introduction of AI technologies, particularly generative AI, into new or existing offerings may result in new or expanded risks and liabilities, due to enhanced

governmental or regulatory scrutiny, litigation, compliance issues, ethical concerns, confidentiality, data privacy or security risks, as well as other factors that could adversely affect our business, reputation, and financial results.

This insurance included coverage for cancellations due to communicable diseases and enabled us to receive an amount up to the lost contribution margin per conference plus incurred expenses, as more specifically set forth in the policies’ provisions for calculating the amount of recoverable loss, and subject to the policies’ limits of liability.

These policies provided up to $170 million in coverage for 2020 cancellations with the right to reinstate the policy limits for the payment of additional premium if those limits are utilized, for a maximum recovery of $340 million.

The insurer has accepted and paid claims on the initial $170 million of 2020 coverage.

We are the plaintiff in litigation with the insurer and are seeking to reinstate the policy limits pursuant to the policies’ reinstatements of limits clause and recover up to an additional $170 million for events cancelled in 2020.

In addition, revenue

Additionally, the laws and enforcement mechanisms to protect our intellectual property from unauthorized use in new technologies like AI and machine learning are evolving and may be inadequate.

From time to time third parties have asserted, and may continue to assert, intellectual property claims that our products infringe the rights of others.

Such claims can be expensive and time-consuming to defend, regardless of their merit.

The inability to obtain rights to use third-party intellectual property on commercially reasonable terms could also have an adverse impact on our business.

We may face claims based on the theft or unauthorized use or disclosure of third-party trade secrets and other confidential business information.

Any such incidents and claims could harm our business and reputation, cause us to incur significant expenses, and prevent us from selling certain products, all of which could negatively impact our business and results of operations.

due to recent regulatory scrutiny in the U.S. If the laws change to provide greater rights to employees, that could further reduce the effectiveness and enforceability of our restrictive covenant agreements.

Cyber criminals use artificial intelligence tools to increase the effectiveness, speed and complexity of attacks, requiring increased vigilance and threat defense.

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 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.

*We face risks related to leased office space.* We lease all the properties used for our ongoing business operations.

Additionally, tariffs, trade barriers

In its recent report, Global Economics Prospects, January 2024, the World Bank reported that global growth is projected to slow to 2.4% in 2024—the third consecutive year of deceleration—reflecting the lagged and ongoing effects of tight monetary policies to rein in decades-high inflation, restrictive credit conditions, and anemic global trade and investment.

The report also notes that downside risks to the outlook predominate.

The recent conflict in the Middle East, coming on top of the Russian invasion of Ukraine, has heightened geopolitical risks.

Conflict escalation could lead to surging energy prices, with broader implications for global activity and inflation.

Other risks highlighted in the report include financial stress related to elevated real interest rates, persistent inflation, weaker-than-expected growth in China, further trade fragmentation, and climate change-related disasters.

The World Bank notes that the expected growth rates for 2024 and 2025 would be far below the 3.1% average of the 2010s.

Additionally, scarcity of fuel and/or rising green energy costs may increase our operations costs or affect client travel to our Conferences.

The SBTi has

approved Gartner’s near-term science-based emissions reductions targets.

In addition, standards and processes for measuring and reporting carbon emissions and other sustainability metrics may change over time, and may result in inconsistent data, or could result in significant revisions to our strategies and targets, or our ability to achieve them.

In May 2023, Gartner entered into a settlement agreement with the SEC, without admitting or denying the SEC’s allegations, which fully resolved this matter.

In December 2022, the European Union adopted a directive requiring member states to incorporate similar provisions into their domestic laws, to be effective as of January 2024 and January 2025.

In 2023, the OECD issued administrative guidance providing transition and safe harbor rules that may effectively delay the application of these legislative changes in certain countries until January 2027.

*The profitability and success of our conferences and other meetings are subject to external factors beyond our control.* Our Conferences business constituted approximately 7% and 5% of total revenues from our on-going operations in 2022 and 2021, respectively.

As a result of the COVID-19 pandemic, we cancelled in-person conferences scheduled for 2020 beginning in late February/early March 2020.

We began holding virtual conferences during the second half of 2020.

These virtual conferences resulted in significantly less revenue and gross contribution, but we believe aided in client retention and engagement.

We had planned in-person conferences for 2021, but cancelled those conferences due to the ongoing pandemic.

We re-launched in-person destination conferences during the second quarter of 2022 and expect to focus on in-person destination conferences in future periods as conditions permit.

Although we have returned to offering some in-person conferences, our Conferences revenues may continue to be negatively impacted if in-person conferences are not permitted to be held in the jurisdictions of the conference venues, if client policies prohibit or restrict business travel or if there are public health concerns for attendees, exhibitors or our employees.

We are in litigation with the insurer on these issues.

In 2021, we received $166.9 million of insurance proceeds related to 2020 event cancellation claims and recorded a gain of $152.3 million.

We received an additional $3.1 million related to 2020 event cancellation insurance claims in February 2023.

In its lawsuit against the insurer, Gartner is seeking to reinstate and recover up to an additional $20 million for cancelled 2020 Evanta meetings and to reinstate and recover up to an additional $150 million in losses from cancelled 2020 destination conferences.

Additionally, as a result of the COVID-19 pandemic, the vast majority of our employees transitioned to working from home.

In early 2022, we began to operate under a hybrid virtual-first working environment, meaning that most of our employees have the option to work remotely at least some of the time for the foreseeable future.

The hybrid working environment may impair our ability to maintain our culture of collaboration and continuous improvement, and may cause disruptions among our employees, including lost productivity, communication challenges and, potentially, employee dissatisfaction and attrition.

Additionally, there can be no assurance that another party will not assert that we have infringed its intellectual property rights.

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.

*We face risks related to leased office space.* We assumed a significant amount of leased office space, in particular in Arlington, Virginia, in connection with the acquisition of CEB Inc. in 2017.

Additionally, the long-term impact of responses to COVID-19 on leased office space availability and rental costs of leased office space is not yet known.

The outstanding debt may limit the

In addition, variable-rate borrowings under our 2020 Credit Agreement typically use LIBOR as a benchmark based on market participant judgments for establishing the rate of interest.

We expect LIBOR to disappear entirely after June 2023 for rates applicable to the 2020 Credit Agreement and our existing derivatives contracts.

The Alternative Reference Rates Committee (ARRC), which was convened by the Federal Reserve Board and the New York Fed, has identified the Secured Overnight Financing Rate (SOFR) as the recommended risk-free alternative rate for USD LIBOR.

The future consequences of a transition away from LIBOR on our variable-rate borrowings, including the possible transition to rates based on observable transactions, such as SOFR, cannot be predicted at this time, but could include an increase in the cost of our variable-rate indebtedness and volatility in our earnings.

In addition, the withdrawal of nations from existing common markets or trading blocs, such as the exit of the United Kingdom (UK) from the European Union (the EU), commonly referred to as Brexit, could be disruptive and negatively impact the business of our clients.

We continue to monitor Brexit and its potential impacts on our results of operations and financial condition.

Depending on the application of the terms of the trade and cooperation agreement, there could be near or long-term negative impacts on our clients who have significant operations in the UK.

This may cause clients in the UK to forgo new purchases, and decrease renewals of subscription-based services and to request to cancel or renegotiate current subscription-based services.

The impact of any of these effects of Brexit, among others, could materially harm our business and financial results.

In its recent report, Global Economics Prospects, January 2023, the World Bank reported that

global growth is projected to decelerate sharply in 2023, to its third weakest pace in nearly three decades, overshadowed only by the 2009 and 2020 global recessions.

According to the World Bank, this reflects policy tightening aimed at containing very high inflation, worsening financial conditions, and continued disruptions from Russia’s invasion of Ukraine.

The report also notes that further negative shocks – such as higher inflation, even tighter policy, financial stress, deeper weakness in major economies, or rising geopolitical tensions – could push the global economy into recession.

*The COVID-19 pandemic had a material adverse impact on our operations and financial performance, specifically our Conferences segment, and may continue to have an adverse impact on our operations.* We face challenges from evolving factors related to the COVID-19 pandemic that are not within our control, remain uncertain and to which we may not effectively respond.

For example, our operations span numerous locations around the world, and many local governments and countries may impose various restrictions on our employees, partners and customers’ physical movement to limit the spread of COVID-19.

These restrictions are constantly changing, and we cannot predict how long and to what extent they will continue.

We also face increased operational hurdles as we make efforts to promote employee health and safety, including limiting travel and implementing a hybrid virtual-first work policy, meaning that most of our employees will have the option to work remotely at least some of the time, for the foreseeable future.

Additionally, for the continuing risks we face in our Conferences segment related to COVID-19, please refer above to the risk factor *“The profitability and success of our conferences and other meetings are subject to external factors beyond our control.”*

Since that time, we have cooperated fully with their review, and we are working toward a resolution.

At this time, we do not believe the ultimate outcome of these matters will have a material effect on our financial results, however, an unexpected adverse resolution of these matters could negatively impact our financial condition, results of operations, and liquidity.

Tax reform legislation is being proposed or enacted in a number of jurisdictions where we do business.

This MD&A provides an analysis of our consolidated financial results, segment results and cash flows for [removed: 2022] [added: 2023] and [removed: 2021] [added: 2022] under the headings “Results of Operations,” “Segment Results” and “Liquidity and Capital Resources.” For a similar detailed discussion comparing [removed: 2021] [added: 2022] and [removed: 2020,] [added: 2021,] refer to those headings under Item 7., “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” in our Annual Report on Form 10-K for the year ended December 31, [removed: 2021.][added: 2022.]

Important factors that could cause our actual results, performance and achievements, or industry results to differ materially from estimates or projections contained in our forward-looking statements include, among others, the following: the impact of general economic conditions, including inflation (and related monetary policy by governments in response to inflation), on economic activity and our operations; changes in macroeconomic and market conditions and market volatility, including interest rates and the effect on the credit markets and access to capital; the impact of global economic and geopolitical conditions, including inflation, [removed: recession] and [removed: the COVID-19 pandemic;] [added: recession;] our ability to carry out our strategic initiatives and manage associated costs; our ability to recover potential claims under our event cancellation insurance; the timing of conferences and meetings, in particular our Gartner Symposium/Xpo series that normally occurs during the fourth quarter; our ability to achieve and effectively manage growth, including our ability to integrate our acquisitions and consummate and integrate future acquisitions; our ability to pay our debt obligations; our ability to maintain and expand our products and services; our ability to expand or retain our customer base; our ability to grow or sustain revenue from individual customers; our ability to attract and retain a professional staff of research analysts and consultants as well as experienced sales personnel upon whom we are dependent, especially in light of [removed: increasing] labor competition; our ability to achieve continued customer renewals and achieve new contract value, backlog and deferred revenue growth in light of competitive pressures; our ability to successfully compete with existing competitors and potential new competitors; our ability to enforce and protect our intellectual property rights; [added: our ability to keep pace with technological developments in artificial intelligence;] additional risks associated with international operations, including foreign currency fluctuations; the impact on our business resulting from changes in international conditions, including those resulting from the [added: conflict in the Middle East, the] war in Ukraine and current and future sanctions imposed by governments or other authorities; the impact of restructuring and other charges on our businesses and operations; cybersecurity incidents; risks associated with the creditworthiness, budget cuts, and shutdown of governments and agencies; our ability to meet ESG commitments; the impact of changes in tax policy (including [removed: the recently enacted Inflation Reduction Act of 2022)] [added: global minimum tax legislation)] and heightened scrutiny from various taxing authorities globally; changes to laws and regulations; and other risks and uncertainties.

Contract value was [removed: $4.7] [added: $4.8] billion at December 31, [removed: 2022,] [added: 2023,] an increase of [removed: 12%] [added: 8%] compared to December 31, [removed: 2021] [added: 2022] on a foreign currency neutral basis.

Conferences revenues increased to [removed: $389.3] [added: $505.2] million in [removed: 2022,] [added: 2023,] an increase of [removed: 82%] [added: 30%] compared to [removed: 2021] [added: 2022] on a reported basis and [removed: 90%] [added: 29%] excluding the foreign currency impact.

The Conferences gross contribution margin was [removed: 54%] [added: 50%] and [removed: 62%] [added: 54%] in [removed: 2022] [added: 2023] and [removed: 2021,] [added: 2022,] respectively.

The Consulting gross contribution margin was [removed: 39%] [added: 35%] and [removed: 38%] [added: 39%] in [removed: 2022] [added: 2023] and [removed: 2021,] [added: 2022,] respectively.

Backlog was [removed: $139.7] [added: $162.1] million at December 31, [removed: 2022.][added: 2023.]

Cash provided by operating activities was [removed: $1.1] [added: $1.2] billion and [removed: $1.3] [added: $1.1] billion during [removed: 2022] [added: 2023] and [removed: 2021,] [added: 2022,] respectively.

As of December 31, [removed: 2022,] [added: 2023,] we had [removed: $698.0 million] [added: $1.3 billion] of cash and cash equivalents and approximately $1.0 billion of available borrowing capacity on our revolving credit facility.

During [removed: 2022,] [added: 2023,] we repurchased [removed: 3.8] [added: 1.8] million shares of the Company’s common stock for an aggregate purchase price of approximately [removed: $1.0] [added: $0.6] billion.

Accounting for income taxes — [removed: The Company uses] [added: We use] the asset and liability method of accounting for income taxes.

We estimate our income taxes in each of the jurisdictions where [removed: the Company operates.][added: we operate.]

[removed: The Company uses] [added: We use] estimates in determining the amount of unrecognized tax benefits associated with uncertain tax positions.

Accounting for stock-based compensation — [removed: The Company accounts] [added: We account] for stock-based compensation awards in accordance with FASB ASC Topics 505 and 718 and SEC Staff Accounting Bulletins No. 107 and No. 110.

[removed: The Company recognizes] [added: We recognize] stock-based compensation expense, which is based on the fair value of the award on the date of grant, over the related service period.

Depreciation increased by 6% during 2023 compared to 2022.

Amortization of intangibles decreased by 6% during 2023 compared to 2022 primarily due to intangible assets divested as part of the sale of our TalentNeuron business.

Gain from sale of divested operation was attributable to the sale of our TalentNeuron business in February 2023.

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

The increase in the effective income tax rate in 2023 was primarily the result of changes in unrecognized tax benefits year over year.

The increase in net income during 2023 was primarily the result of the gain from sale of divested operations, as well as increased revenue and interest income, partially offset by increased operating expenses, a lower gain from de-designated interest rate swaps and higher income tax expense.

The gross contribution margin was 74% in both 2023 and 2022, as the increase in revenue and decreased research program expenses were offset by an increase in personnel expenses to support future growth.

The decrease in GTS and GBS wallet retention was largely due to lower levels of incremental spending by existing clients compared to the same period in 2022.

| | | | 2023 | | | | | | 2022 | | | | | | | | |

The year-over-year increase was primarily due to increased operating income, excluding the gain from sale of divested operation, and strong collections, partially offset by increased income tax payments, in part as a result of the gain from sale of divested operation in 2023.

The increase from 2022 to 2023 was primarily the result of the proceeds received from the sale of our TalentNeuron business in February 2023.

During the 2023 period, we used $0.6 billion of cash for share repurchases and paid a net $7.8 million in debt principal repayments.

Recent Events

The invasion of Ukraine by Russia and the sanctions and other measures being imposed in response to this conflict have increased the level of economic and political uncertainty.

In March 2022, we began winding down our business in Russia.

Russia has not composed a material portion of our consolidated revenues, net income, net assets or workforce.

We do not have a business in Ukraine.

Other impacts due to this evolving situation are currently unknown and could subject our business to materially adverse consequences should the situation escalate or cause an expansion of economic disruption beyond its current scope to the rest of Europe, where a material portion of our business is carried out.

A prolonged disruption may adversely affect our business operations, financial performance and results of operations.

Inflation rates, particularly in North America and Europe, have increased significantly in the past year.

Inflation has not had a material effect on our business operations, financial performance and results of operations, other than its impact on the general economy.

However, if our costs, in particular personnel-related costs, were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases in future periods.

Our inability or failure to realize these offsets could adversely affect our business operations, financial performance and results of operations.

On August 16, 2022, the Inflation Reduction Act of 2022 was enacted into law in the United States.

The statute includes a 15% corporate alternative minimum tax on U.S. corporations with adjusted financial statement income in excess of $1.0 billion which is effective for taxable years beginning after December 31, 2022.

The statute also includes a 1% excise tax on publicly traded U.S. corporations for the value of any of its stock that is repurchased by the corporation, excluding certain excepted repurchases.

We do not expect it will have a material impact on our future U.S. tax expense, cash taxes and effective tax rate.

We also do not expect it to have a material impact on the amount of potential future share repurchases.

In November 2022, we entered into a definitive agreement to sell our TalentNeuron business.

As of December 31, 2022, the assets and liabilities of TalentNeuron were considered held for sale, resulting in $49.0 million of assets held for sale and $30.8 million of liabilities held for sale on the Consolidated Balance Sheet.

The majority of the held for sale assets were goodwill, intangible assets, net and accounts receivable, with carrying amounts of $16.0 million, $9.5 million and $15.9 million, respectively, while the majority of the held for sale liabilities was deferred revenues, with a carrying amount of $27.1 million.

The year ended December 31, 2021 also included expenses related to cancelled conferences.

Depreciation decreased by 9% during 2022 compared to 2021.

Amortization of intangibles decreased by 10% during 2022 compared to 2021 due to certain intangible assets that became fully amortized in 2021.

The increase is primarily due to expenses related to the pending divestiture of our TalentNeuron business.

The 2021 effective tax rate includes a benefit of approximately $54.1 million from intercompany sales of certain intellectual property, while no such benefit occurred in 2022.

This benefit represents the value of future tax deductions for amortization of the assets in the acquiring jurisdiction, net of any tax recognized in the selling jurisdiction.

The Company’s intellectual property footprint continues to evolve and may result in tax rate volatility in the future.

As of December 31, [removed: 2022,] [added: 2023,] the Company had $2.5 billion in total debt principal outstanding.

Approximately [removed: $282.0] [added: $274.0] million of the Company’s total debt outstanding as of December 31, [removed: 2022] [added: 2023] was based on a floating base rate of interest, which potentially exposes the Company to increases in interest rates.

However, we reduce our overall exposure to interest rate increases through our interest rate swap contract, which effectively [removed: convert] [added: converts] the floating base interest rates on all of our variable rate borrowings to fixed rates.

At December 31, [removed: 2022,] [added: 2023,] we had [removed: $698.0 million] [added: $1.3 billion] of cash and cash equivalents, with a substantial portion denominated in foreign currencies.

If the exchange rates of the foreign currencies we hold all changed in comparison to the U.S. dollar by 10%, the amount of cash and cash equivalents we would have reported on December 31, [removed: 2022] [added: 2023] could have increased or decreased by approximately [removed: $42.9] [added: $79.3] million.

Our outstanding foreign currency forward exchange contracts as of December 31, [removed: 2022] [added: 2023] had an immaterial net unrealized gain.

We believe our people are our most valuable asset, enabling our [removed: long] [added: sustained] track record of [removed: global] growth.

At December 31, [removed: 2022,] [added: 2023,] we had [removed: approximately 19,500] [added: 20,237] employees globally, [removed: approximately 9,110] [added: 9,514] of which were outside of the U.S., and the overwhelming majority of our employees were full time.

Gartner currently has [removed: six] [added: seven] formal ERGs supporting underrepresented racial, ethnic and multicultural backgrounds, women, the LGBTQ+ community, [removed: veterans] [added: veterans,] and [removed: employees] [added: people] with disabilities.

In [removed: 2022,] [added: 2023,] over [removed: 5,300] [added: 6,000] Gartner associates were members of at least one ERG.

In addition to salaries, these programs (which vary by country/region) include annual bonuses, stock awards, an employee stock purchase plan, 401(k) matching, healthcare and insurance benefits, tax savings programs, such as health and dependent care flexible spending accounts, health savings account and pretax commuter benefits, generous paid time off, paid parental leave, life and disability insurance, business travel accident insurance, charity matching, employee assistance programs, tuition assistance and on-site services, such as [removed: health centers and] fitness centers, among others.

Since our Sales and Research & Advisory teams make up approximately [removed: 50%] [added: 45%] of total employees worldwide, we also have formal, dedicated programs to help train and onboard new hires as well as more experienced managers and leaders within Sales and Research & Advisory.

In [removed: 2021,] [added: 2023,] Gartner [removed: transformed] [added: continued to transform and refine] how we onboard new sales [removed: hires] [added: associates,] so they more quickly develop the core competencies tied to sales success.

Gartner, Inc. (NYSE: IT) delivers actionable, objective insight that drives smarter decisions and stronger performance on an organization’s mission-critical priorities.

Our vision is to help build a high-performing organization with a culture of equity and inclusion, enabling Gartner to guide the leaders who shape the world.

Our DEI

Our employees work in 39 different countries and territories.

As we continue to invest in employee self-identification and reporting efforts, we determined our employees were represented by more than 130 self-identified nationalities.

We continue to invest in learning opportunities to develop DEI at Gartner through training modules on important topics such as bias, empathy, equity, equality and individual identity.

Our learning resources provide Gartner associates with awareness and clarity of expectations, equip managers with knowledge and skills to lead inclusively and support team effectiveness, inclusion and belonging.

Total Rewards

We believe our total rewards programs facilitate associate retention and also encourage high performance.

In 2023 more than 6,500 sales associates participated.

Survey results are used for a number of enterprise-wide and business-unit-specific initiatives targeting key areas of engagement and retention, such as leadership effectiveness, career development, business process improvement, and more.

In 2023, associate turnover continued to decrease as compared with the prior year.

Our average tenure increased slightly from 4.5 years

in 2022 to 5.0 years, primarily due to a decrease in associate turnover and a heavy focus on growth through Gartner internal mobility initiatives.

Finally, in 2023, the Science Based Targets initiative validated our near-term emissions targets.

We provide associates an opportunity to engage on environmental sustainability topics and help advance our Net-Zero strategy through the Gartner Green Team, a voluntary, associate-driven group.

In 2023, the Green Team had over 750 members.

Additionally, we introduced a sustainability training module available to all associates interested in learning more about Gartner’s sustainability efforts.

Our expert guidance and tools enable faster, smarter decisions and stronger performance on an organization’s mission critical priorities.

Our DEI efforts are all about building the confidence and conviction in all of our associates – but particularly in our leaders - to do the right things and building a

language of inclusion to foster this.

On a worldwide basis, our employees were represented by more than 85 self-identified nationalities working in 38 different countries and territories.

We also continue to invest in learning opportunities to develop DEI at Gartner.

For example, in addition to our popular Embracing Diversity & Being Inclusive training module, which covers the importance of diversity and inclusion at Gartner and the role of unconscious bias, we added a new module this year called Equity vs. Equality, which focuses on fostering a more equitable workplace.

Health, Safety and Compensation

We believe that our equity grants facilitate retention as well as encourage performance of key personnel.

We operate under a hybrid virtual-first working arrangement, which provides additional flexibility to employees, enabling most of our employees to work remotely a substantial portion of the time.

In 2022, we expanded the program, and more than 3,100 sales associates participated.

Business-unit-specific survey results are used for a number of leader-specific interventions, from individualized coaching to team-based skill-building to business-unit-wide initiatives targeting key areas of engagement.

While we experienced a decrease in associate turnover in 2022, our average employee tenure decreased from 5.1 years in 2021 to 4.5 years in 2022, primarily due to increased new hires in 2022.

We have implemented a layered cybersecurity program to assess, identify, and manage risks from cybersecurity threats that may result in material adverse effects on the confidentiality, integrity, and availability of our information systems, networks, and data systems.

Our cybersecurity program is generally aligned with the National Institute of Standards and Technology (NIST) Cybersecurity Framework.

Information Security Team and Governance.

The Audit Committee has the primary responsibility of assisting our Board of Directors in overseeing risk related to cybersecurity matters.

The Board and/or the Audit Committee receive quarterly cybersecurity-related reports from our Chief Information Officer (CIO), which may address a wide range of topics, such as: cybersecurity strategy, the threat environment, the status of ongoing information security program initiatives, and information security program metrics.

Additionally, we have documented protocols by which certain cybersecurity incidents that meet established reporting thresholds are escalated within the Company and, where appropriate, reported to the Board and/or the Audit Committee.

At the management level, our CIO, who reports directly to the CEO, has over 20 years of experience serving in IT management, software development, and technology-based roles across a variety of industries, including publishing, media and entertainment, and financial and insurance services.

Our Chief Information Security Officer (CISO), who reports directly the CIO, has extensive cybersecurity knowledge and skills gained from over 15 years of work experience serving in security roles for the Company and a variety of financial service firms.

Our CISO is responsible for understanding, managing, and communicating cybersecurity risk internally to our management, and works closely with Legal to oversee compliance with legal, regulatory, and contractual security requirements.

Our CISO heads the Information Security Team, which is responsible for implementing, monitoring, and maintaining cybersecurity and data protection practices across our business.

The Information Security Team covers a wide range of cyber and information security responsibilities.

Our CISO also receives reports on cybersecurity threats on an ongoing basis and regularly reviews risk management measures implemented by the Company to identify and mitigate cybersecurity risks.

In addition to our internal capabilities, we also engage external consultants, legal counsel, or other third-party advisors to assist with assessing, identifying, and managing cybersecurity risks.

Risk Management and Strategy.

Cybersecurity risk management, which involves resource commitments and management attention, is overseen both as a critical component of our overall risk management program and as a standalone program.

We have implemented a risk-based, cross-functional approach to identifying, preventing, and mitigating cybersecurity threats and incidents, while also implementing controls and procedures that provide for the prompt escalation of certain cybersecurity incidents.

Our cybersecurity program uses a layered strategy, relying on technology and human processes to safeguard our client’s data at all layers.

We embed controls within our business processes and technology development, starting with design and engineering and extending to operations.

Our defense-in-depth strategy utilizes numerous layers of security controls, processes, and procedures across our information systems and networks, including but not limited to, vulnerability management, multi-factor authentication (MFA), identity access management (IAM), endpoint security, mobile security, application security, encryption, network security, web security, and event monitoring and logging.

Aspects of our program undergo several independent third-party audits and reviews on a regular basis.

We maintain a written Information Security Policy, which establishes the foundational components of our cybersecurity program and our high-level security responsibilities over all technologies, facilities and data.

When engaging service providers and third-party vendors, we perform due diligence to assess whether these providers have appropriate privacy and security controls, and we generally require these providers to implement appropriate protective measures, and to use confidential information solely for the purposes of performing their services.

Additionally, we have adopted a documented Incident Response Plan that applies in the event of a cybersecurity incident to provide a standardized framework for response.

In general, our incident response process follows the NIST 800-61 framework and focuses on four phases: preparation; detection and analysis; containment, eradication and recovery; and post-incident remediation.

We have implemented a security training and awareness program for all Gartner employees and third-party contractors.

Employees receive security training in connection with onboarding as well as annual awareness and training activities throughout their employment.

Further, Gartner carries cybersecurity insurance covering the company and its subsidiaries.

Material Cybersecurity Risks, Threats & Incidents.

While we have not experienced any material cybersecurity threats or incidents, there can be no guarantee that we will not be the subject of future successful attacks, threats or incidents.

Additional information on cybersecurity risks we face can be found in Part I, Item 1A “Risk Factors” of this Report under the heading “Strategic and Operational Risks – *We are exposed to risks related to cybersecurity,*” which should be read in conjunction with the foregoing information.
