PART I

Item 1. Business

As used herein, unless the context otherwise requires, ISG, the registrant, is referred to in this Annual Report on Form 10-K for the fiscal year ended December 31,2023 (“Form 10-K”) as the “Company,” “we,” “us” and “our.”

Our Company

Information Services Group, Inc. (Nasdaq: III) is a leading global technology research and advisory firm. A trusted business partner to more than 900 clients, including more than 75 of the top 100 enterprises in our markets, ISG is committed to helping corporations, public sector organizations and service and technology providers achieve operational excellence and faster growth. The Company specializes in digital transformation services, including automation, cloud and data analytics; sourcing advisory; managed governance and risk services; network carrier services; technology strategy and operations design; change management; market intelligence and technology research and analysis. Based in Stamford, Connecticut, ISG employs over 1,500 digital-ready professionals operating in more than 20 countries—a global team known for its innovative thinking, market influence, deep industry and technology expertise, and world-class research and analytical capabilities based on the industry’s most comprehensive marketplace data. For more information, visit www.isg-one.com. The content on our website is available for informational purposes only. It should not be relied upon for investment purposes, nor is it incorporated by reference into this Form 10-K or any other filings.

Our Company was founded in 2006 with the strategic vision to become a high-growth, leading provider of information-based advisory services. We continue to believe that our vision will be realized through the acquisition, integration and successful operation of market-leading brands within the data, analytics and advisory industry.

Our private and public sector clients continue to face significant technological, business and economic challenges that will fuel demand for the professional services we provide. We are focused on providing unique solutions that solve key client problems. In the private sector, for example, we believe that companies will continue to face significant challenges associated with globalization and technological innovation, including the need to decrease operating costs, increase efficiencies, compete against new market entrants and evaluate and adopt increasing numbers of emerging and transformational technologies such as Generative AI. Similarly, public sector organizations at the national, regional and local levels increasingly must deal with the complex and converging issues of outdated technology systems, reduced budgets and an aging workforce. These technological challenges have only been intensified by the post-COVID-19 pandemic remote or hybrid work environment and, therefore, present further opportunity for ISG to assist our private and public sector clients with digital transformation services.

Overall, we believe the global marketplace dynamics at work in both the private and public sectors support growing demand for the professional services, analytics, platforms and advice ISG can provide. In this dynamic environment, the strength of our client relationships greatly depends on the quality of our advice and insight, our unique and valuable datasets, the independence of our thought leadership and the effectiveness of our people in assisting our clients to implement strategies that successfully address their most pressing operational challenges.

We are organized as a corporation under the laws of the State of Delaware. The current mailing address of the Company’s principal executive office is Information Services Group, Inc., 2187 Atlantic Street, Stamford, CT 06902. Our telephone number is (203) 517-3100.

Our Services

ISG specializes in digital transformation services, including sourcing advisory, automation, cloud and data analytics; managed governance and risk services; network carrier services; technology strategy and operations design; change management; market intelligence and technology research and analysis. ISG supports both private and public sector organizations to transform and optimize their operational environments. During periods of expansion or contraction, our services have helped organizations of all sizes across the globe address their most complex operational issues. The functional domain experience of our experts and deep empirical data resources allows clients to better understand their strategic options.

The Company’s operating model is aimed at extending our market leadership, enhancing growth opportunities and driving significant value for all stakeholders. We provide services that address our clients’ most pressing business challenges in two areas most important to them—their continuing digital transformation and getting the most from their digital investments. To meet these needs, we formed two global client solution areas: ISG Digital, focused on developing technology, transformation, sourcing and digital solutions for clients, and ISG Enterprise, focused on helping clients manage change and optimize operations in such areas as finance, human resources (“HR”) and Procure2Pay.

Our core solutions are supported by ISG Research, with its extensive market analyses and provider evaluations, our ISG Network and Software Advisory services and our software platforms, including ISG GovernX®. We also continue to build more industry-specific capabilities in such areas as banking, insurance and smart manufacturing.

Every client engagement passes through our dedicated Solution Hub to bring the best thinking, tools and capabilities to bear to solve every client challenge. Integrated solutions are then delivered through our ISG iFlex™ global delivery model, which enables us to rapidly deploy our resources to support clients, regardless of geography or time zone.

Our Competitive Advantages

We believe that the following strengths differentiate us from our competition:

| · | Independence and Objectivity. We are not an information technology or business process outsourcing service provider. Rather, we are an independent, fact-based data, analytics and advisory firm with no material conflicting financial or other interests. This enables us to maintain a trusted advisor relationship with our clients through our unbiased focus and ability to align our interests with those of our clients.

| · | Proprietary Data Assets and Market Intelligence. We have assembled a comprehensive and unique set of data, analytics and market intelligence built over more than 30 years of data collection and analysis, providing insight into the comparative cost and quality of a variety of operational alternatives.

| ● | Domain Expertise. Averaging over 20 years of experience, our strategic consulting teams bring a wealth of industry and domain-specific knowledge and expertise to address our clients’ most complex transformational needs.

| · | Strong Brand Recognition. ISG continues to gain marketplace awareness as a leading brand in our industry. ISG offers integrated solutions to our clients.

| · | Global Reach. We possess practical experience in global business operations, and we understand the significance of interconnected economies and companies. Our resources in the Americas, Europe and Asia Pacific make us a truly global advisory firm able to consistently serve the strategic and implementation needs of our clients.

We believe the above strengths are central to our ability to successfully advise and support our clients to address any business challenge.

Our Strategy

We intend to use our competitive strengths to develop new services and products, sustain our growth and strengthen our existing market position by pursuing the following strategies:

| · | Preserve and Expand Our Market Share Positions. We expect the trend toward globalization and greater operating efficiency and technological innovation to play an increasing role in the growth in demand for our services. We plan to leverage our combined operating platform to serve the growing number of private and public sector organizations utilizing outside advisors when undertaking transformational projects. We are focused on growing our existing client base by offering integrated solutions that combine our multiple services and capabilities. In addition, we will seek to continue to expand our products and services and the geographic markets we serve opportunistically as global competition spurs demand for cost savings and value creation.

| ● | Preserve Our Financial Positions. In our pursuit of the Company’s growth initiatives, we are committed to maintaining a strong financial position with flexibility and liquidity. The priorities for uses of available cash include payment of dividends, funding growth, repurchases of shares and debt reduction. In addition, we expect our cash flow generation and a solid balance sheet to support the current financial strategy.

| · | Strengthen Our Industry Expertise. We strive to continue to strengthen our market-facing organization to drive increased revenue around 9 global industries: Banking and Financial Services, Consumer Services, Energy and Utilities, Health Sciences, Insurance, Manufacturing, Media and Technology Software and Services, Private Equity and Public Sector.

| · | Aggressively Expand Our Market Focus. We are seeking to drive our service portfolio and relationships with clients further into Digital Advisory Services, including Generative AI, Automation, Business Advisory Services, Strategy, Data & Analytics, Transition and Organizational Change and Network & Software Advisory. These are all areas in which we are investing additional focus to drive increased revenues and expanded relationships with clients.

ISG plans to expand resources and intellectual property (“IP”) around digitization. Our purpose in the digital marketplace is to be a trusted advisor, guiding our clients through digital transformation toward practical innovation of their business models, leveraging strategic partners, emerging technology and thought leadership.

Our digital services now span a volume of offerings and have become embedded as part of our traditional transaction services. Advancements continue to be made to further ‘digitize’ our traditional services. For example, we continue to modernize our traditional sourcing services to bring agility, nimbleness and AI capability to the process of sourcing, RFPs and contracting. Our ISG Tango sourcing platform is a unique and comprehensive solution that helps enterprises and public sector organizations to quickly evaluate their business requirements, identify desired outcomes, fast-track the provider identification and selection process, collaborate with providers on developing the right solution, get to a signed contract and transition operations faster than before.

ISG continues to expand its Supplier and Contract Management capabilities powered by the GovernX® platform, the market’s leading vendor compliance and risk management digital solution. This service provides clients a strategic and disciplined approach to managing supplier relationships and large contract portfolios. These services assist clients with improving supplier performance, reducing spend, mitigating third party risk, and managing/collaborating/innovating with their supplier base. Based on ISG’s 25 years of managing relationships on behalf of our clients, we have a unique and robust dataset that enables ISG to partner with clients to deliver improvements to their business processes and to benchmark the performance of their operations to the broader market. ISG GovernX leverages cognitive technology to automate the management of third-party supplier relationships, including contract and project lifecycles and risk management. Enterprises can leverage the platform to deliver more value from their outsourcing spend. ISG GovernX users can easily manage new contracts and proactive renewals, make timely amendments and handle contract terminations—all on one platform. The platform delivers easy integration with other enterprise applications, such as ServiceNow, and is tightly connected to ISG Research offerings, such as benchmarks, assessments and total-cost-of-ownership evaluations. Additionally, ISG GovernX clients can mitigate supply chain risks and ensure business continuity by reviewing and validating their providers’ business and IT continuity plans and procedures. ISG GovernX includes real-time third-party risk management capabilities, including integrated data feeds and real-time alerts, which are increasingly important as provider ecosystems grow more complex, introducing more risk to the enterprise, and threats against supply-chain integrity become more diverse. In addition to monitoring the operational performance and financial viability of their suppliers, ISG GovernX helps enterprises address a range of other internal and external risks, from data security and regulatory issues, to adverse environmental, health and geopolitical events, to social responsibility, diversity and inclusion considerations.

We continue to invest in ISG Inform™ 2.0, an enhanced version of our data-as-a-service solution that provides benchmarking capability to track digital transformation and application development maturity and performance against industry peers. ISG Inform 2.0 provides a quantified view of the health of the user’s enterprise IT landscape through a series of easy-to-read visual dashboards that display key performance indicators for infrastructure, applications and digital capabilities compared with industry peers. Data and insights are drawn from the ISG sourcing database.

Robotic Process Automation coupled with Generative AI is fundamentally reshaping the way businesses work. Automation is increasingly enabling automated 24/7/365 execution of business processes at a fraction of the cost of human equivalents, as well as leading to dramatic improvements in process execution and cost models. The addition of Generative AI will allow companies to automate “high touch” functions and processes historically requiring human focus.

ISG Automation offers clients a full portfolio of services, including automation and Generative AI assessments and strategy, proof-of-concept deployments, implementation and integration of software bots, and establishment of centers of excellence to scale automation, as well as training and managed services.

| ● | Expand Emerging Services. The focus will be on creating repeatable methods used to drive growth of emerging services, including Generative AI; ISG Automation; ISG Network Select™; HR Technology & Transformations; Providers-as-a-Business; ISG Platform; ISG Digital Engineering; ISG Research; and ISG Training-as-a-Service.

| 1. | ISG Generative AI: ISG is significantly influencing how our clients adopt Generative Artificial Intelligence (GenAI). As these companies transform into AI-powered enterprises, ISG provides crucial buying advice, access to diverse AI technologies and niche implementors via a marketplace, and impartial governance solutions. By offering a comprehensive understanding of various AI providers and platforms, ISG helps companies make informed decisions that align with their specific needs. This strategic advice is essential in an ever-evolving AI landscape. ISG also assists clients in adapting to these changes by helping them reassess the value of their traditional IT operations and contracts with partners - in the context of AI-enhanced productivity. This reassessment or 'marking to market' is crucial for companies to realize the full benefits of AI integration.

​

| 2. | ISG Automation: ISG’s capabilities and service offerings include implementation services for Robotic Process and Cognitive Automation Technology. ISG Automation guides clients through the hurdles of adoption, ensuring the optimal future state with best-fit technologies. ISG Automation tailors programs to specific business needs and helps build governance that works inside the culture of our clients. The size of the Automation market is expected to continue to grow significantly over the next few years. Automation is fundamentally reshaping the world of Information Technology Outsourcing and Business Process Outsourcing. Our solutions will work to optimize repetitive processes using ‘bots’

|  | instead of human labor. ISG Automation will continue to be marketed by industry (e.g., claims processing for insurance) and by back-office functions (e.g., accounting).

| 3. | ISG Network Select: This offering helps streamline and simplify how enterprises build their network solutions. It enables ISG to better meet the growing demand for such leading-edge networking solutions as software-defined networking (SD-WAN, SD-LAN), SD security services, 5G mobility, unified communications-as-a-service (UCaaS) and call center-as-a-service (CCaaS) — which are all critical to enterprise digital transformation. Client demand for networks that are secure, interconnected, interoperable and profitable is rising, as are concerns over security, scale, cost and the complexity of the expanding Internet of Things (“IoT”) landscape. ISG Network Select is designed to help clients find the best solutions, faster, to power their digital transformation initiatives. Clients get access to detailed and current data on their vendor and technology options, insights to help negotiate better pricing, and processes to accelerate ISG Tango networking solutions.

| 4. | HR Technology & Transformations: Advances in technology are transforming the business of HR. From intuitive and mobile self-service software to predictive analytics and integrated talent management suites, technological solutions are changing the way leaders acquire, develop and engage their employees. New applications, enhanced functionality and competition among software providers make it difficult to stay on top of this ever-evolving space. ISG combines deep subject matter expertise, market data and financial frameworks along with sourcing of technology and service providers to help organizations develop and execute HR technology strategies that are right for them.

| 5. | Providers-as-a-Business: Historically, ISG had targeted traditional service providers for these types of services, which included a combination of consulting and research solutions. These services include market intelligence, client retention programs, pursuit effectiveness, satisfaction benchmarking, go-to-market consulting and health checks.

| 6. | ISG Platform: We see growth opportunities in tool-enabling the part of consulting that solves for standard problems. The digital solutioning of ISG will reach its next level as we develop the ISG Platform, an integrated set of software-driven solutions, data and research that will allow us to increase our subscription-based recurring revenues and penetrate new market segments. ISG Inform and ISG GovernX will be at the core of the ISG Platform, as will our new set of offerings that will continue to streamline and digitize the provider selection process. In early 2022, ISG launched ISG Executive Insights™, a market intelligence and data analytics platform that addresses the challenges of managing increasingly complex supplier ecosystems. The new data-analytics-as-a-solution offering is powered by ISG’s market-leading data repository—a comprehensive, curated database of global IT, business process and engineering outsourcing contracts—paired with ISG’s patented IT price benchmarking, market cost intelligence and other analytical tools. We continue to develop and invest in our ISG Platform, which will help us drive recurring revenues.

| 7. | ISG Digital Engineering: ISG has an opportunity to develop and scale a Digital Engineering capability that meets the growing need of enterprises to integrate information technology, operational technology and engineering technology. Over the past five years, enterprise business models have been shifting from selling products as a one-time transaction to becoming more software-oriented to drive more features and functionality, shifting focus to aftermarket solutions to generate recurring revenues via services (servitization) and enhancing customer experience to increase customer acquisition and retention rates. As companies are reimagining their products and services, Digital Engineering is growing rapidly due to the increasing data and software content of products and processes. Our aim is to become an independent governance and end-to-end transformation partner including the sourcing of engineering system integrators and engineering platforms like SIEMENS and Dassault throughout each client’s digital engineering transformation journey, serving multiple industries with an initial focus on manufacturing.

| 8. | ISG Research: In today's digital marketplace, ISG helps large enterprises confront emerging challenges, prepare for new opportunities and ensure they stay ahead of competitors. With a powerful mix of advisory, digital transformation and research capabilities, ISG helps close the gap between where enterprises are and where they need to be. ISG Research has a focus on bringing buyers and sellers of technology together, including large service, cloud and software providers. Our advisory business gives ISG Research a unique perspective on the overall technology and sourcing market. Our research not only incorporates what a traditional analyst firm might cover, but also actual feedback and perspectives from practitioners in the market who are helping some of the largest enterprise clients transform their business. ISG tracks over 180,000 unique technology service contracts and measures and writes about more than 4,000 service and software providers each year. This gives us valuable insights into pricing, capabilities and stability. When large enterprises need to evaluate providers, they reach out to ISG Research for a deep understanding of capabilities, pricing, breadth of coverage and past experience. With the rapid pace of technology including GenAI, ISG Research is ready and well-positioned with buyers and sellers to ensure our clients avoid the hype and capitalize on outcomes.

| 9. | Training-as-a-Service (TaaS): ISG has launched a subscription-based, recurring revenue service that has lowered training development costs at major clients called Training as a Service (TaaS). Building on this success, ISG offers outsourced managed learning services for organizations with limited resources and growing demand for custom learning content and

8

Table of Contents

|  | digital learning platforms. These organizations are typically looking for longer-term training support to address the needs of an evolving workforce. ISG TaaS uses an agile approach with rapid content development tools to accelerate training content and digital adoption platforms (DAP) to integrate learning into the daily flow of work. Services include training advisory, analysis, strategy, custom development, delivery support, learning software subscription models, learning administration, and learning assessment.

| ● | Expand “Recurring Revenue Streams.” These include such annuity-based ISG offerings as ISG GovernX, ISG Research, Software-as-a-Subscription, ISG Inform and the multi-year Public Sector contracts. All are characterized by subscriptions (i.e., renewal-centric as opposed to project-centric revenue streams) or multi-year contracts. As companies begin to recognize the importance of managing the post-sourcing transaction period, managed services have emerged as a revenue driver for the Company, with our offerings delivered through multi-year managed services contracts. We believe that our experience with outsourcing transactions and software implementation initiatives makes us uniquely equipped to provide research insight and direct support to help our clients manage their transformational projects or act as a third-party administrator. We will continue to pursue opportunities to leverage our experience to make research and managed services an even greater revenue generator for us. The U.S. public sector, particularly state governments, local municipalities and higher education, presents a significant opportunity to ISG. Systems are typically outdated; maintenance is expensive and the workforce charged with maintenance is aging. There is a need to refurbish systems to reduce the cost of operations (particularly because governments’ tax revenues are under pressure). We are well-positioned as a third party, objective advisory group with no affiliation to the software providers. ISG will continue to invest in the digitization of these services, driving increased automation, greater profitability and even more value for our clients.

| ● | Consider Acquisitions and Other Growth Opportunities. The business services, information and advisory market is highly fragmented. We believe we are well-positioned to leverage our leading market positions and strong brand recognition to expand through acquisitions and other growth opportunities. Acquiring firms with complementary services and products would allow us to further develop and broaden our service offerings and domain expertise. We will consider and may pursue opportunities to enter joint ventures and to buy or combine with other businesses.

One of our core assets is the information, data, analytics, methodologies and other intellectual property the Company possesses. This intellectual property underpins the independent nature of our operational assessments, strategy development, deal structuring, negotiation and other consulting services we provide to our clients.

With each engagement we conduct, we enhance both the quantity and quality of the intellectual property we employ on behalf of our clients, thus providing a continuous, evolving and unique source of information, data and analytics.

This intellectual property is proprietary, and we rely on multiple legal and contractual provisions and devices to protect our intellectual property rights. We recognize the value of our intellectual property and vigorously defend it. As a result, the Company maintains strict policies and procedures regarding ownership, use and protection of our intellectual property with all parties, including our employees.

Clients

We operate in over 20 countries and across numerous industries. Our private sector clients operate primarily in the manufacturing, banking and financial services, insurance, health sciences, energy and utilities and consumer services industries. Our private sector clients are primarily large businesses ranked in the Forbes Global 2000 companies annually. Our public sector clients are primarily state and local governments (cities and counties) and authorities (airport and transit) in the United States and national and provincial government units in the United Kingdom, Italy and Australia.

Competition

Competition in the sourcing, data, information and advisory market is primarily driven by independence and objectivity, expertise, possession of relevant benchmarking data, breadth of service capabilities, reputation and price. We compete with other sourcing advisors, research firms, strategy consultants and sourcing service providers. A significant number of independent sourcing and advisory firms offer similar services to us. We believe we set ourselves apart with our data repository of recent, comparable transactions and benchmarking data, our depth of experience and our sourcing and technology implementation expertise, all of which are critical to implementing and managing successful transformation projects for business and governments.

Employees

As of December 31, 2023, we employed 1,518 people worldwide.

Table of Contents

Our employee base includes executive management, service leads, partners, directors, advisors, analysts, technical specialists and functional support staff.

We recruit advisors from service providers and consulting firms with direct operational experience. These advisors leverage extensive practical expertise derived from experiences in corporate leadership, consulting, research, financial analysis, contract negotiations and operational service delivery.

All employees are required to execute confidentiality, conflict of interest and intellectual property agreements as a condition of employment. There are no collective bargaining agreements covering any of our employees.

Our voluntary advisor turnover rate has ranged between 12% and 15% over the last three years.

Human Capital Management

ISG strives to employ the brightest, most innovative people in the industry, so that we can provide world-class solutions to our clients. Employees at ISG are anchored in our core values, which include trust, integrity, respect, diversity, passion, entrepreneurship, balance and mentorship.

Our more than 1,500 employees, located in over 20 countries with more than one-fourth in the United States, perform a variety of different roles. We are participants in the competitive research and advisory industries. Attracting, developing and retaining talented people in advisory, research and other positions is critical to executing on our strategy. Our ability to compete effectively depends upon a number of factors, including learning opportunities, compensation/benefits, work environment, career opportunities and a culture of inclusivity. To make this happen, we have certain programs, training, policies and practices in place, including the following:

Diversity/Inclusion

ISG believes a key to our success is our value of diverse backgrounds, experiences and cultures. Our employees function within a collaborative community that welcomes varied ideas and styles. These diverse perspectives produce enhanced results for our clients and result in a preferred place to work.

We exhibit our commitment to diversity and inclusion through our hiring practices, opportunities for learning and advancement and the distribution of rewards. Through efforts such as our Inclusion, Diversity, Equity and Awareness (IDEA) team and Women-In-Digital industry group, we are able to help in the identification and advancement of diverse talent. We strive to provide a culture where each employee is able to bring their whole self to work. While we have made progress in our workforce diversity representation, we seek to continually improve in this area.

ISG WorkLife

We have also introduced ISG WorkLife, which is a series of progressive, best practice, Next-Gen HR offerings designed to improve the quality of our work-life experience, while helping us achieve our firm-wide objectives. ISG believes this will help us attract and retain productive talent. Some of the key offerings here include:

| ● | ISG Cares, our enhanced volunteering program, which, among other things, provides employees paid time off to attend to charitable pursuits.

| ● | ISG Academy, our global learning and development program.

| ● | ISG Aspire, our global mentoring program.

| ● | ISG iRefer, which allows the Company to attract talent through employee referrals, for which employees may earn referral bonuses.

| ● | ISG iTime, which provides flexible paid time off arrangements for employees in certain countries.

| ● | ISG Brand Ambassador, which highlights and encourages our people’s community support and charitable pursuits while elevating the firms global brand.

​

We understand that employees have varied interests both in and outside of the workplace. These programs, and others under ISG WorkLife, provide employees with the opportunity to pursue these activities. This allows us to attract and retain productive employees and enhance diverse perspectives.

Environmental Social and Governance (ESG)

The ISG Environmental Social and Governance program was developed with corporate commitment and accountability on a global level in mind. The program has oversight and executive support to drive real, positive change in alignment with our value and policies, ultimately enabling us to maximize impact and value.

Our ISG Go Green program speaks to the Environmental pillar of ESG. This program seeks to reduce our carbon footprint via awareness and education initiatives that share green practices for ISG employees in both virtual and physical offices. Additionally, ISG is developing measurable carbon reduction best practices that align with our goals for sustainable business operations. Since 2021, we have offset the carbon generated by ISG employee travel and continue to seek ways to pivot to green energy for our physical locations. Our environmental work is centered around three core concepts: compliance with eco-friendly laws and best practices, prevention of waste, pollution and carbon emissions and continuous, measurable improvement.

The IDEA (Inclusion, Diversity, Equity and Awareness) program is the foundation for our Social pillar. Beyond our core Diversity, Equity and Inclusion (DEI) activities, ISG has sub-groups that devote focus to uplifting women in digital, maintaining equitable recruitment, building our supplier diversity and volunteering through our global ISG Cares team. At ISG, we do not just accept difference — we celebrate it, and we thrive on it for the benefit of our employees, our clients and our communities. We commit to building a team that represents a variety of backgrounds, perspectives and skills. ISG is proud to be an equal opportunity workplace, and we are committed to creating an inclusive environment for all employees. Our work in the social pillar is based on ISG values of trust, integrity, respect and diversity, made tangible in our business practices, modern slavery statement and fair labor policies.

For the Governance pillar, ISG has a well-established set of policies, governing bodies and independent validation measures. ISG is governed on a day-to-day basis by our internal international executive board, which meets weekly. ISG also receives governance and support from an external board of directors (“the Board of Directors”). We maintain procedures, policies and codes of conduct around ethical business practices, whistleblowing, suppliers, data protection, information security, privacy, confidentiality, employee comportment and travel. With regard to cybersecurity, we regularly provide training, reporting and scans in compliance with our ISO-27001 certifications and best practices. Every year, our employees attest to reviewing our global policies via digital signature, including in 2023 a new policy regarding the acceptable use of generative automated intelligence.

Learning

ISG’s success depends on the knowledge and productivity of its employees. To that end, the Company invests a significant amount of time and money into providing development opportunities. Our ISG Academy is robust in offering learning in such topics specific to the employee’s industry and functional areas, leadership and people management, certifications and software and technical skills, among others. In 2023, most learning was virtual; there were over 1,200 digital certified professionals that participated in various sessions, devoting a total of more than 45,000 hours to learning and development.

Item 1A. Risk Factors

We operate in a highly competitive and rapidly changing environment that involves numerous risks and uncertainties, some of which are beyond our control. In addition, we and our clients are affected by global economic conditions and trends. The following sections address significant factors, events and uncertainties that make an investment in our securities risky. We urge you to consider carefully the factors described below and the risks that they present for our operations, as well as the risks addressed in other reports and materials that we file with the SEC and the other information included or incorporated by reference in this Form 10-K. When the factors, events and contingencies described below or elsewhere in this Form 10-K materialize, there could be a material adverse impact on our business, prospects, results of operations, financial condition and cash flows, any of which could have a potential negative effect on the trading price of our common stock. Additional risks not currently known to us or that we now deem immaterial may also harm us and negatively affect your investment. 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 give rise to or amplify many of these risks discussed below. Risks in this section are grouped in the following categories: (1) risks related to outstanding debt; (2) risks related to acquisitions; (3) strategy and operation risks; (4) risks related to management and employees; (5) macroeconomic risks; (6) risks related to data, cybersecurity and confidential information; and (7) general risk factors. Many risks affect more than one category, and the risks are not in order of significance or probability of occurrence because they have been grouped by categories.

Risks Related to Outstanding Debt

We have a substantial amount of debt outstanding, which may limit our ability to fund general corporate requirements and obtain additional financing, limit our flexibility in responding to business opportunities and competitive developments and increase our vulnerability to adverse economic and industry conditions and changes in our debt rating.

On February 22, 2023, the Company amended and restated its senior secured credit facility to increase the revolving commitments per the revolving facility (the “2023 Credit Agreement”) from $54.0 million to $140.0 million and eliminate its term loan. As a result of the substantial variable costs associated with the debt obligations, we expect that:

| ● | a decrease in revenues will result in a disproportionately greater percentage decrease in earnings;

| ● | we may not have sufficient liquidity to fund all of these variable costs if our revenues decline or costs increase;

| ● | we may have to use our working capital to fund these variable costs instead of funding general corporate requirements, including capital expenditures;

| ● | we may not have sufficient liquidity to respond to business opportunities, competitive developments and adverse economic conditions; and

| ● | our results of operations will be adversely affected if interest rates increase because, based on our current outstanding borrowings in the amount of $79.2 million as of December 31, 2023, a 1% increase in interest rates would result in a pre-tax impact on earnings of approximately $0.8 million per year.

These debt obligations may also impair our ability to obtain additional financing, if needed, and our flexibility in the conduct of our business. Our indebtedness under the senior secured revolving credit facility is secured by substantially all of our assets, leaving us with limited collateral for additional financing. Moreover, the terms of our indebtedness under the senior secured revolving credit facility restrict our ability to take certain actions, including the incurrence of additional indebtedness, mergers and acquisitions, investments and asset sales. Our ability to pay the fixed costs associated with our debt obligations will depend on our operating performance and cash flow, which in turn depend on general economic conditions and the advisory services market. A failure to pay interest or indebtedness when due could result in a variety of adverse consequences, including the acceleration of our indebtedness. In such a situation, it is unlikely that we would be able to fulfill our obligations, repay the accelerated indebtedness or otherwise cover our fixed costs. As of December 31, 2023, the total principal outstanding under the revolving credit facility was $79.2 million.

Our failure to comply with the covenants in our credit agreement could materially and adversely affect our financial condition and liquidity.

Our credit agreement contains financial covenants requiring that we maintain, among other things, certain leverage and interest coverage ratios. Poor financial performance could cause us to be in default of these covenants. While we were in compliance with these covenants as of December 31, 2023, there can be no assurance that we will remain in compliance in the future. If we fail to comply with the covenants in our credit agreement, we may have to seek an amendment or waiver from our lenders to avoid the termination of their commitments and/or the acceleration of the maturity of outstanding amounts under the credit facility. The cost of our obtaining an amendment or waiver could be significant, and further, there can be no assurance that we would be able to obtain an amendment or waiver.

12

Table of Contents

If our lenders were unwilling to enter into an amendment or provide a waiver, all amounts outstanding under our credit facility would become immediately due and payable.

Our variable rate indebtedness will subject us to interest rate risk, which could cause our annual debt service obligations to increase significantly.

Borrowing under our credit facility bears interest at a rate per annum equal to either (i) the “Base Rate” (which is the highest of (a) the rate publicly announced from time to time by the administrative agent as its “prime rate,” (b) the Federal Funds Rate plus 0.5% per annum and (c) Term SOFR, plus 1.0%), plus the applicable margin (as defined below) or (ii) Term SOFR (which is the Term SOFR screen rate for the relevant interest period plus a credit spread adjustment of 0.10%) as determined by the administrative agent, plus the applicable margin. The applicable margin is adjusted quarterly based upon the Company’s consolidated leverage ratio. If interest rates increase, our debt service obligations on our variable rate indebtedness would increase even though the amount borrowed remained the same, and our cash flows could be adversely affected. An increase in debt service obligations under our variable rate indebtedness could affect our ability to make payments required under the terms of our credit facility.

Risks Related to Acquisitions

We have risks associated with acquisitions or investments.

Since our inception, we have expanded through acquisitions. In the future, we plan to pursue additional acquisitions and investments as opportunities arise. We may not be able to successfully integrate businesses that we acquire in the future without substantial expense, delays or other operational or financial problems. We may not be able to identify, acquire or profitably manage additional businesses. If we pursue acquisition or investment opportunities, these potential risks could disrupt our ongoing business, result in the loss of key customers or personnel, increase expenses and otherwise have a material adverse effect on our business, results of operations and financial condition.

Difficulties in integrating businesses we have acquired, or may acquire in the future, may demand time and attention from our senior management.

Integrating businesses we have acquired, or may acquire in the future, may involve unanticipated delays, costs and/or other operational and financial problems. In integrating acquired businesses, we may not achieve expected economies of scale or profitability or realize sufficient revenue to justify our investment. If we encounter unexpected problems as we try to integrate an acquired firm into our business, our management may be required to expend time and attention to address the problems, which would divert their time and attention from other aspects of our business.

Strategy and Operation Risks

Our operating results have been, and may in the future be, adversely affected by worldwide economic conditions and credit tightening.

Our results of operations are affected by the level of business activity of our clients, which in turn is affected by the level of economic activity in the industries and markets that they serve. A decline in the level of business activity of our clients, such as the impact of a pandemic, inflation, slowing growth, rising interest rates and recession, could have a material adverse effect on our revenue and profit margin. Future economic conditions could cause some clients to reduce or defer their expenditures for consulting services. We have implemented and will continue to implement cost-savings initiatives to manage our expenses as a percentage of revenue. However, current and future cost-management initiatives may not be sufficient to maintain our margins if the economic environment should weaken for a prolonged period.

The rate of growth in the broadly defined business information services and advisory sector and/or the use of technology in business may fall significantly below the levels that we currently anticipate.

Our business is dependent upon continued growth in sourcing activity, the use of technology in business by our clients and prospective clients and the continued trend towards sourcing of complex information technology and business process tasks by large and small organizations. If sourcing diminishes as a management and operational tool, the growth in the use of technology slows down or the cost of sourcing alternatives rises, our business could suffer. Companies that have already invested substantial resources in developing in-house information technology and business process functions may be particularly reluctant or slow to move to a sourcing solution that may make some of their existing personnel and infrastructure obsolete.

Table of Contents

Our engagements may be terminated, delayed or reduced in scope by clients at any time.

Our clients may decide at any time to abandon, postpone and/or reduce our involvement in an engagement. Our engagements can be terminated, or the scope of our responsibilities may be diminished, with limited advance notice. If an engagement is terminated, delayed or reduced unexpectedly, the professionals working on the engagement could be underutilized until we assign them to other projects. Accordingly, the termination or significant reduction in the scope of a single large engagement, or multiple smaller engagements, could harm our business results.

Our operating results may fluctuate significantly from period to period as a result of factors outside of our control.

Our revenues and operating results may vary significantly from accounting period to accounting period due to factors including:

● fluctuations in revenues earned on contracts;

● commencement, completion or termination of engagements during any particular period;

● additions and departures of key advisors;

● transitioning of advisors from completed projects to new engagements;

● seasonal trends;

● introduction of new services by us or our competitors;

● changes in fees, pricing policies or compensation arrangements by us or our competitors;

● strategic decisions by us, our clients or our competitors, such as acquisitions, divestitures, spin-offs, joint ventures, strategic investments or changes in business strategy;

● global economic and political conditions and related risks, including acts of terrorism, war, such as the war in Ukraine and the conflict in the Middle East, pandemics, inflation, slowing growth, rising interest rates and recession; and

● conditions in the travel industry that could prevent our advisors from traveling to client sites.

We depend on project-based advisory engagements, and our failure to secure new engagements could lead to a decrease in our revenues.

Advisory engagements typically are project-based. Our ability to attract advisory engagements is subject to numerous factors, including the following:

● delivering consistent, high-quality advisory services to our clients;

● tailoring our advisory services to the changing needs of our clients;

● matching the skills and competencies of our advisory staff to the skills required for the fulfillment of existing or potential advisory engagements; and

● maintaining a global business operation.

Any material decline in our ability to secure new advisory arrangements could have an adverse impact on our revenues and financial condition.

If we are unable to achieve or maintain adequate utilization for our consultants, our operating results could be adversely impacted.

Our profitability depends to a large extent on the utilization of our consultants. Utilization of our consultants is affected by a number of factors, including:

● additional hiring of consultants because there is generally a transition period for new consultants;

● the number and size of client engagements;

● the unpredictability of the completion and termination of engagements;

● our ability to transition our consultants efficiently from completed engagements to new engagements;

● unanticipated changes in the scope of client engagements or unexpected terminations of client engagements; and

14

Table of Contents

● our ability to maintain an appropriate level of consultants by forecasting the demand for our services.

We could lose money on our fixed-fee or capped-fee contracts.

As part of our strategy, from time to time, we enter into fixed-fee contracts, in addition to contracts based on payment for time and materials with capped fees. Because of the complexity of many of our client engagements, accurately estimating the cost, scope and duration of a particular engagement can be a difficult task. If we fail to make accurate estimates, we could be forced to devote additional resources to these engagements for which we will not receive additional compensation. While losses on our fixed-fee contracts are rare, to the extent that an expenditure of additional resources is required on an engagement, this could reduce the profitability of, or result in a loss on, the engagement.

Our contracts with contingent-based revenue may cause unusual variations in our operating results.

As part of our strategy, from time to time, we earn incremental revenues, in addition to hourly or fixed-fee billings, which are contingent on the attainment of certain contractual milestones or objectives. Because it is uncertain when the milestones or objectives will be achieved, if ever, any such incremental revenues may cause unusual variations in quarterly revenues and operating results. Also, whether any contractual milestones or objectives are achieved may become subject to dispute.

We may not be able to maintain our existing services and products.

We operate in a rapidly evolving market, and our success depends upon our ability to deliver high-quality advice and analysis to our clients. Any failure to continue to provide credible and reliable information and advice that is useful to our clients could have a significant adverse effect on future business and operating results. Further, if our advice proves to be materially incorrect and the quality of service is diminished, our reputation may suffer and demand for our services and products may decline. In addition, we must continue to improve our methods for delivering our products and services in a cost-effective manner.

Expanding our service offerings may not be profitable.

We may choose from time to time to develop new service offerings because of market opportunities or client demands. Developing new service offerings involves inherent risks, including:

● a lack of market understanding;

● competition from more established market participants;

● our inability to estimate demand for the new service offerings; and

● unanticipated expenses to hire qualified consultants and to market our new service offerings.

If we cannot manage the risks associated with new service offerings effectively, we are unlikely to be successful in these efforts, which could harm our ability to sustain profitability.

We may not have the ability to develop and offer the new services and products that we need to remain competitive.

Our future success will depend in part on our ability to offer new services and products. To maintain our competitive position, we must continue to enhance and improve our services and products, develop or acquire new services and products in a timely manner and appropriately position and price new services and products relative to the marketplace and our costs of producing them. These new services and products must successfully gain market acceptance by addressing specific industry and business sectors and by anticipating and identifying changes in client requirements. The process of researching, developing, launching and gaining client acceptance of a new service or product, or assimilating and marketing an acquired service or product, is risky and costly. We may not be able to introduce new, or assimilate acquired, services and products successfully. Any failure to achieve successful client acceptance of new services and products could have an adverse effect on our business results.

We may fail to anticipate and respond to market trends.

Our success depends in part upon our ability to anticipate rapidly changing technologies and market trends and to adapt our advice, services and products to meet the changing sourcing advisory needs of our clients. Our clients regularly undergo frequent and often dramatic changes. That environment of rapid and continuous change presents significant challenges to our ability to provide our clients with current and timely analysis, strategies and advice on issues of importance to them. Meeting these challenges requires the commitment of substantial resources. Any failure to continue to respond to developments, technologies and trends in a manner that meets market needs could have an adverse effect on our business results.

Table of Contents

We may be unable to protect important intellectual property rights.

We rely on copyright and trademark laws, as well as nondisclosure and confidentiality arrangements, to protect our proprietary rights in our methods of performing our services, our data and our tools for analyzing financial and other information. There can be no assurance that the steps we have taken to protect our intellectual property rights will be adequate to deter misappropriation of our rights or that we will be able to detect unauthorized use and take timely and effective steps to enforce our rights. If substantial and material unauthorized uses of our proprietary methodologies, data and analytical tools were to occur, we may be required to engage in costly and time-consuming litigation to enforce our rights. There can be no assurance that we would prevail in such litigation. If others were able to use our intellectual property or were to independently develop our methodologies or analytical tools, our ability to compete effectively and to charge appropriate fees for our services may be adversely affected.

We face competition and our failure to compete successfully could materially adversely affect our results of operations and financial condition.

The business information services and advisory sector is highly competitive, fragmented and subject to rapid change. We face competition from many other providers ranging from large organizations to small firms and independent contractors that provide specialized services. Our competitors include any firm that provides sourcing or benchmarking advisory services, IT strategy or business process consulting, which may include a variety of consulting firms, service providers, niche advisors and, potentially, advisors currently or formerly employed by us. Some of our competitors have significantly more financial and marketing resources, larger professional staffs, closer client relationships, broader geographic presences or more widespread recognition than us.

In addition, limited barriers to entry exist in the markets in which we do business. As a result, additional new competitors may emerge, and existing competitors may start to provide additional or complementary services. There can be no assurance that we will be able to successfully compete against current and future competitors and our failure to do so could result in loss of market share, diminished value in our products and services, reduced pricing and increased marketing expenditures. Furthermore, we may not be successful if we cannot compete effectively on quality of advice and analysis, timely delivery of information, client service or the ability to offer services and products to meet changing market needs for information, analysis or price.

We derive a significant portion of our revenues from our largest clients and could be materially and adversely affected if we lose one or more of our large clients.

Our 25 largest clients accounted for approximately 33% and 35% of revenue in 2023 and 2022, respectively. If one or more of our large clients terminate, significantly reduce their engagement or fail to remain a viable business, then our revenues could be materially and adversely affected. In addition, sizable receivable balances could be jeopardized if large clients fail to remain a going concern.

Risks Related to Management and Employees

The loss of key executives could adversely affect our business.

The success of our business is dependent upon the continued service of a relatively small group of key executives, including Michael P. Connors, Chairman and Chief Executive Officer; Todd D. Lavieri, Vice Chairman and President – ISG Americas and Asia Pacific; Michael A. Sherrick, Executive Vice President and Chief Financial Officer; and Thomas S. Kucinski, Executive Vice President and Chief Human Resources Officer, among others.

Although we currently intend to retain our existing management, we cannot assure that such individuals will remain with us for the immediate or foreseeable future. The unexpected loss of the services of one or more of these executives could adversely affect our business.

We rely heavily on key members of our management team.

We are dependent on our management team. We grant restricted stock units (“RSUs”) from time to time to key employees and, in connection with such grants, require recipients to execute a restrictive covenant agreement. Vested and unvested RSUs will be forfeited upon any violation of the restrictive covenant agreement. We may not be able to retain these managers and may not be able to enforce the restrictive covenants. If we were to lose a number of key members of our management team and were unable to replace these people quickly, we could have difficulty maintaining our growth and certain key relationships with large clients and face competition from these former managers if the restrictive covenants are unenforceable.

We depend upon our ability to attract, retain and train skilled advisors and other professionals.

Our business involves the delivery of advisory and consulting services. Therefore, our continued success depends in large part upon our ability to attract, develop, motivate, retain and train skilled advisors and other professionals who have advanced information technology and business processing domain expertise, financial analysis skills, project management experience and other similar abilities. These advisors could resign and join one of our competitors or provide sourcing advisory services to our clients through their own ventures.

16

Table of Contents

We must also recruit staff globally to support our services and products. We face competition for the limited pool of these 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 a greater ability to attract and compensate these professionals. Moreover, increasing wage inflation may affect our profit margin as we strive to provide compensation packages that are competitive. We face risks related to global labor shortages, and competitive markets have increased attrition throughout our sector. Some of the personnel that we attempt to hire may be subject to non-compete agreements that could impede our short-term recruitment efforts. Any failure to retain key personnel or hire and train additional qualified personnel as required supporting the evolving needs of clients or growth in our business could adversely affect the quality of our products and services, and our future business and operating results.

We may have agreements with certain clients that limit the ability of particular advisors to work on some engagements for a period of time.

We provide services primarily in connection with significant or complex sourcing transactions and other matters that provide potential competitive advantage and/or involve sensitive client information. Our engagement by a client occasionally precludes us from staffing certain advisors on new engagements with other clients because the advisors have received confidential information from a client who is a competitor of the new client. Furthermore, it is possible that our engagement by a client could preclude us from accepting engagements with such client’s competitors because of confidentiality concerns.

Macroeconomic Risks

Our international operations expose us to a variety of risks that could negatively impact our future revenue and growth.

Approximately 39% of our revenues for 2023 and 42% of our revenue for 2022 were derived from sales outside of the Americas. Our operating results are subject to the risks inherent in international business activities, including:

● tariffs and trade barriers;

● regulations related to customs and import/export matters;

● restrictions on entry visas required for our advisors to travel and provide services;

● tax issues, such as tax law changes and variations in tax laws as compared to the United States;

● cultural and language differences;

● an inadequate banking system;

● foreign exchange controls;

● restrictions on the repatriation of profits or payment of dividends;

● crime, strikes, riots, civil disturbances, pandemics, terrorist attacks and wars, such as the war in Ukraine and the conflict in the Middle East;

● nationalization or expropriation of property;

● law enforcement authorities and courts that are inexperienced in commercial matters; and

● deterioration of political relations with the United States.

Air travel, telecommunications and entry through international borders are all vital components of our business. If a pandemic, military conflict, or terrorist attack were to occur, our business could be disproportionately impacted because of the disruption, including potential cancellation of ISG events.

Further, conducting business abroad subjects us to increased regulatory compliance and oversight. For example, in connection with our international operations, we are subject to laws prohibiting certain payments to governmental officials, such as the Foreign Corrupt Practices Act of 1977, as amended. A failure to comply with applicable regulations could result in regulatory enforcement actions as well as substantial civil and criminal penalties assessed against us and our employees.

We intend to continue to expand our global footprint in order to meet our clients’ needs. This may involve expanding into countries beyond those in which we currently operate, including into less-developed countries that may have less political, social or economic stability and less-developed infrastructure and legal systems. As we expand our business into new countries, regulatory, personnel, technological and other difficulties may increase our expenses or delay our ability to start up operations or become profitable in such countries. This may affect our relationships with our clients and could have an adverse effect on our business.

17

Table of Contents

We operate in a number of international areas which exposes us to significant foreign currency exchange rate risk.

We have significant international revenue, which is predominantly collected in local currency. It is expected that our international revenues will continue to grow as European and Asian Pacific markets adopt sourcing solutions. The translation of our revenues into U.S. dollars, as well as our costs of operating internationally, may adversely affect our business, results of operations and financial condition.

Risks Related to Data, Cybersecurity and Confidential Information

Data protection laws and self-regulatory codes may restrict our activities and increase our costs.

Various statutes and rules regulate conduct in areas such as privacy and data protection that may affect our collection, use, storage, and transfer of information both abroad and in the United States. Compliance with these laws and self-regulatory codes may require us to make certain investments or may dictate that we not offer certain types of services or only offer such services after making necessary modifications. Failure to comply with these laws and self-regulatory codes may result in, among other things, civil and criminal liability, negative publicity, restrictions on further use of data and/or liability under contractual warranties.

In addition, there is an increasing public concern regarding data and consumer protection issues, with the result that the number of jurisdictions with data protection laws continues to increase and the scope of existing privacy laws and the data considered to be covered by such laws keep expanding. Changes in these laws (including newly released interpretations of these laws by courts and regulatory bodies) may limit our client data access, use and disclosure, and may require increased expenditures by us or may dictate that we may not offer certain types of services.

As a global firm, ISG must comply with various international and domestic data privacy regulations such as (i) the EU and UK General Data Protection Regulation (“GDPR”), which has extra-territorial scope and substantial fines for breaches (up to 4% of global annual revenue or €20 million, whichever is greater), (ii) the California Consumer Privacy Act, which, unlike data privacy provisions enacted by other US states, covers individuals acting in a commercial or employment context not just as consumers, and (iii) the Australian Privacy Act, among others. In addition, the new India Digital Personal Data Protection Act 2023 (“DPDP”) is likely to come into force in 2024. Like the GDPR, the DPDP has extra-territorial reach. The DPDP shares many provisions with existing privacy laws, and ISG therefore anticipates that its existing processes already broadly align with the new law. However, like the GDPR, failure to comply with the DPDP may lead to substantial fines. ISG is continuing to monitor the development of the EU’s ePrivacy Regulation proposal and industry response and will determine whether to take further action, as needed, if it is adopted.

To mitigate the risk and negative exposure of data outside ISG, we have put in place a data protection framework that includes policies, procedures, guidance, and records. This includes policies and procedures for rights and usage of personal and client data.

We are exposed to risks related to cybersecurity.

A significant portion of our business is conducted over the internet, and we rely on the secure processing, storage, and transmission of confidential, sensitive, proprietary and other types of information relating to our business operations and confidential and sensitive information about our clients and employees in our computer systems and networks, and in those of our third-party vendors. Individuals, groups, and state-sponsored organizations may take steps that pose threats to our operations, our computer systems, our employees, and our clients. The cybersecurity risks we face range from cyberattacks 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 other coordinated disruptions, to more advanced threats that target us because of our prominence in the global research and advisory field. Ransomware risk has increased significantly in recent years and presents a significant risk of financial extortion and loss of data. Our operating model allows employees to continue to work remotely or on a hybrid basis, which magnifies the importance of the integrity of our remote access security measures.

We have robust measures in place to address and mitigate cyber-related risks. Notwithstanding this, we continue to experience attack attempts against our environment. We have and continue to expect to invest in the security and resiliency of our networks and products and to enhance our internal controls and processes, which are designed to help protect our systems and infrastructure and the information they contain. These include timely detection of incidents through monitoring, training, incident response capabilities, and mitigating cyber and security risks to our data, systems, products, and services. However, given the complex, continuing and evolving nature of cyber and other security threats, these efforts may not be fully effective, particularly against previously unknown vulnerabilities that could go undetected for an extended period.

We also face risks related to our use of third-party suppliers if such suppliers are affected by a cybersecurity threat or incident, which could result in a reduction in or loss of their ability to service us (which could be a significant component of our services to clients), the exposure of ISG or client data or a potential backdoor into ISG’s systems and network.

We may be subject to claims for substantial damages by our clients arising out of disruptions to their businesses or inadequate service, and our insurance coverage may be inadequate.

Most of our service contracts with clients contain service level and performance requirements, including requirements relating to the quality of our services. Failure to consistently meet service requirements of a client or errors made by our employees while delivering services to our clients could disrupt the client’s business and result in a reduction in revenues or a claim for damages against us. Additionally, we could incur liability if a process we manage for a client were to result in internal control failures or impair our client’s ability to comply with their own internal control requirements.

Under our service agreements with our clients, our liability for breach of our obligations is generally limited to actual damages suffered by the client and is typically capped at the greater of an agreed amount or the fees paid or payable to us under the relevant agreement. These limitations and caps on liability may be unenforceable or otherwise may not protect us from liability for damages. In addition, certain liabilities, such as claims of third parties for which we may be required to indemnify our clients or liability for breaches of confidentiality, are generally not limited under those agreements. Although we have general commercial liability insurance coverage, the coverage may not continue to be available on acceptable terms or in sufficient amounts to cover one or more large claims. The successful assertion of one or more large claims against us that exceed available insurance coverage or changes in our insurance policies (including premium increases or the imposition of large deductible or co-insurance requirements) could have a material adverse effect on our business.

We could be subject to liability and our reputation could be damaged if our confidential information or client data is compromised through security breaches, cyberattacks or otherwise.

We may be liable to our clients for damages caused by disclosure of confidential information or personal data. We are often required to collect and store sensitive or confidential client data to perform the services we provide under our contracts. Many of our contracts do not limit our potential liability for breaches of confidentiality. If any person, including any of our current or former employees, penetrates our network security or misappropriates sensitive data or if we do not adapt to changes in data protection legislation, we could be subject to significant liabilities to our clients or to our clients’ customers for breaching contractual confidentiality provisions or privacy laws. Also, we could face cyber-based attacks and attempts by hackers and similar unauthorized users to gain access to or corrupt our information technology systems to gain access to confidential information and client data. Such attacks could disrupt our business operations, cause us to incur unanticipated losses or expenses, and result in unauthorized disclosures of confidential or proprietary information.

We could have liability, or our reputation could be damaged, if we fail to protect client and/or our data from security breaches or cyberattacks.

We are dependent on information technology networks and systems to securely process, transmit and store electronic information and to communicate among our locations around the world and with our people, clients, alliance partners and vendors. As the breadth and complexity of this infrastructure continues to grow, because of the use of mobile technologies, social media and cloud-based services, the risk of security breaches and cyberattacks increases. Such breaches could lead to shutdowns or disruptions of or damage to our systems and those of our clients, alliance partners and vendors and unauthorized disclosure of sensitive or confidential information, including personal data.

In addition, Third Party Cyber Security Risk is a critical focus for us. All potential new suppliers go through our Data Protection Impact Assessment (“DPIA”) process. This starts with an initial screening questionnaire. The questionnaire covers what personal data and client data is processed, whether the third party has any access requirements to our environment and how is data is transferred. From this, our security team assesses the third party, conducts further due diligence, and reviews contractual clauses. If the risk assessment identifies that the baseline Information Security & Privacy technical and organizational controls are not met, the business will be advised accordingly. The outcome of all DPIAs is recorded on the DPIA register. All new third parties processing personal data or client data are assessed to be either Tier 1, 2 or 3, with Tier 1 being the highest risk in terms of data processed or interactions to our environment from a cyber security threat perspective. Tier 1 and 2 third parties are recorded on our business-critical services register and reviewed annually, and we review the compliance documentation, such as latest ISO certifications, SOC2 reports and pen tests, of those Tier 1 and 2 third parties. Tier 3 third parties are recorded on the DPIA register, but no further due diligence is performed by the security team, as Tier 3 third parties process no client or personal data and have no access or integration to ISG’s network or systems. As part of our continuous improvement in our third-party risk management process, we plan to engage the services of a third-party risk monitoring services to monitor threat intelligence and known vulnerabilities.

Although we seek to prevent, detect, and investigate cybersecurity threats and incidents, and have taken steps to mitigate the likelihood of network security breaches, there can be no assurance that attacks by unauthorized users will not be attempted in the future or that our security measures will be effective. Unauthorized disclosure of sensitive or confidential client data, whether through breach of our processes, systems or otherwise, could subject us to liability, damage our reputation and cause us to lose existing and potential clients. We may also be subject to civil actions and/or criminal prosecution by government or quasi-government agencies for breaches relating to such

data. Our insurance coverage for breaches or mismanagement of such data may not continue to be available on reasonable terms or in sufficient amounts to cover one or more large claims against us.

Client restrictions on the use of client data could adversely affect our activities.

Most of the data we use to populate our databases comes from our client engagements. The insight sought by clients from us relates to the contractual data and terms, including pricing and costs, to which we have access while assisting our clients in the negotiation of our sourcing agreements. Data is obtained through the course of our engagements with clients who agree to contractual provisions permitting us to consolidate and utilize on an aggregate basis such information. If we were unable to utilize key data from previous client engagements, our business, financial condition, and results of operations could be adversely affected.

​

General Risk Factors

Failure to maintain effective internal control over financial reporting could adversely affect our business and the market price of our common stock.

Pursuant to rules adopted by the SEC implementing Section 404 of the Sarbanes Oxley Act of 2002, we are required to assess the effectiveness of our internal control over financial reporting and provide a management report on our internal control over financial reporting in all annual reports. This report contains, among other matters, a statement as to whether or not our internal control over financial reporting is effective and the disclosure of any material weaknesses in our internal control over financial reporting identified by management.

The Committee of Sponsoring Organizations of the Treadway Commission (COSO) provides a framework for companies to assess and improve their internal control systems. Auditing Standard No. 5 provides the professional standards and related performance guidance for auditors to attest to, and report on, management’s assessment of the effectiveness of internal control over financial reporting under Section 404. Management’s assessment of internal control over financial reporting requires management to make subjective judgments and, some of the judgments will be in areas that may be open to interpretation. Therefore, our management’s report on our internal control over financial reporting may be difficult to prepare, and our auditors may not agree with our management’s assessment.

While we currently believe our internal control over financial reporting is effective, we are required to comply with Section 404 on an annual basis. If, in the future, we identify one or more material weaknesses in our internal control over financial reporting during this continuous evaluation process, our management will be unable to assert such internal control is effective. Therefore, if we are unable to assert that our internal control over financial reporting is effective in the future, or if our auditors are unable to express an opinion on the effectiveness of our internal control, our investors could lose confidence in the accuracy and completeness of our financial reports, which could have an adverse effect on our business and the market price of our common stock.

Our actual operating results may differ significantly from our guidance.

From time to time, we release guidance regarding our future performance that represents our management’s estimates as of the date of release. This guidance, which consists of forward-looking statements, is prepared by our management and is qualified by, and subject to, the assumptions and the other information contained or referred to in the release. Our guidance is not prepared with a view toward compliance with published guidelines of the Public Company Accounting Oversight Board (United States) (the “PCAOB”), and neither our independent registered public accounting firm nor any other independent expert or outside party compiles or examines the guidance and, accordingly, no such person expresses any opinion or any other form of assurance with respect thereto. Guidance is based upon a number of assumptions and estimates that, while presented with numerical specificity, is inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond our control and are based upon specific assumptions with respect to future business decisions, some of which will change. The principal reason that we release this data is to provide a basis for our management to discuss our business outlook with analysts and investors. We do not accept any responsibility for any projections or reports published by any such persons. Guidance is necessarily speculative in nature, and it can be expected that some or all of the assumptions of the guidance furnished by us will not materialize or will vary significantly from actual results. Accordingly, our guidance is only an estimate of what management believes is realizable as of the date of release. Actual results will vary from the guidance and the variations may be material. Investors should also recognize that the reliability of any forecasted financial data diminishes the farther in the future that the data is forecast. In light of the foregoing, investors are urged to put the guidance in context and not to place undue reliance on it. Any failure to successfully implement our operating strategy or the occurrence of any of the events or circumstances set forth in this Annual Report on Form 10-K could result in the actual operating results being different than the guidance, and such differences may be adverse and material.

Item 1C. Cybersecurity

ISG maintains a cyber risk management program designed to identify, assess, manage, mitigate, and respond to cybersecurity threats. This program is integrated within the Company’s enterprise risk management system and addresses both the corporate information technology environment and the Company’s client-facing products. We regularly assess the threat landscape, taking a holistic view of cybersecurity threats, as such term is defined in Item 106(a) of Regulation S-K.

The underlying controls of the cyber risk management program are based on recognized best practices and standards for cybersecurity and information technology. ISG performs annual assessments, by two independent third parties, against the International Organization Standardization (“ISO”) 27001 Information Security Management System requirements for which we maintain certification. ISG also maintains certification across other cyber security frameworks, including the Trusted Information Security Assessment Exchange and UK Cyber Essentials, and is preparing for SOC2 attestation across our GovernX platforms.

The Company’s cybersecurity efforts are led by the Chief Information Security Officer (“CISO”), who reports to the Chief Information Officer (“CIO”) and has responsibilities that cover the management of cybersecurity risk and the protection and defense of our networks and systems. Our CISO has proven cyber operations and cyber risk management experience, having previously worked for UK law enforcement and leading organizations in the financial services, health and advertising sectors. Our CISO also holds relevant cyber management qualifications, such as being a Certified Information Systems Security Professional. The CISO manages a team of qualified cybersecurity professionals with broad experience and expertise across cyber security disciplines that provide ad-hoc reports to the CISO regarding cybersecurity threats and incidents. Cybersecurity risk is maintained and managed under our Information Security Management System framework with oversight through our internal Executive Board (“IEB”) and our Board of Directors, which has delegated responsibility for cybersecurity risk to our Information Security Committee (“ISC”).

Cybersecurity is an important area of focus for our Board of Directors. The Board of Directors reviews and discusses with our CIO the Company’s cybersecurity, privacy and data security programs, the status of projects to strengthen internal cybersecurity, results from third-party assessments, any significant cybersecurity incidents and the emerging threat landscape. Our CIO discusses the same cybersecurity topics covered with the Board of Directors with the IEB. In addition, the IEB makes decisions on resourcing and project prioritization in support of our cybersecurity and compliance initiatives.

Responsibility for cybersecurity risk has been delegated to the ISC, which consists of senior executives (including three IEB members), namely the Chief Financial Officer (IEB member), Chief Human Resources Officer (IEB member), Chief Information Officer, Chief Data and Analytics Officer (IEB member), Chief Information Security Officer, Legal Counsel, Director of Corporate Governance and Data Privacy Manager. The ISC oversees the management of processes for identifying and mitigating cybersecurity risks, material vulnerabilities and high rated incidents, to help align our risk exposure with our strategic objectives. The ISC meets quarterly and receives additional ad-hoc briefings from the CISO as and when required.

In the event of a major security incident, certain members of the ISC form part of our Incident Management Team (“IMT”). The IMT follows our detailed incident response playbook, which outlines the steps to be followed from incident detection to mitigation, recovery and notification, including notifying functional areas (e.g., legal), as well as senior leadership, the IEB and the Board of Directors, as appropriate.

For the evaluation of our security controls, ISG engages third-parties services to conduct penetration testing, independent audits or provide consulting on best practices to address new challenges. These evaluations include testing both the design and operational effectiveness of our security controls. We also share and receive threat intelligence which we utilize to bolster defenses against active threats. These tests and assessments are useful tools for maintaining a robust cybersecurity program to protect our investors, clients, employees, vendors, intellectual property and drive continuous improvement across the security domain.

ISG recognizes that if our third-party suppliers are affected by cyber security incidents, we could be indirectly impacted, including, the potential loss of service (which could be a significant component of our services to clients), exposure of ISG or client data or a potential backdoor into ISG systems or network. We maintain processes and procedures to continuously assess third-party cybersecurity risk and include security and privacy addendums to our contracts where applicable. We seek to work directly with any suppliers to address potential deficiencies when identified.

To mitigate the risk and negative exposure of personal data being breached or inadvertently shared outside of ISG, we maintain a data protection framework that includes policies, procedures, guidance and records. This includes policies and procedures regarding the rights and usage of personal and client data. ISG employs a Data Privacy Manager who briefs the ISC on privacy matters as part of the quarterly ISC meetings. The Data Privacy Manager completes an internal audit annually and works with a specialist third party to complete an external Data Protection Compliance review.

We continue to invest in the cybersecurity and resiliency of our networks and to enhance our internal controls and processes, which are designed to help protect our systems and infrastructure, and the information they contain.

As of the date of this Annual Report on Form 10-K, we are not aware of any cybersecurity threats, including as a result of any previous cybersecurity incidents, that have materially affected, or are reasonably likely to materially affect, the Company, including our business strategy, results of operations or financial condition. Notwithstanding the extensive approach we take to cybersecurity, we may not be successful in preventing or mitigating cybersecurity threats or incidents, and such threats or incidents may have a material adverse effect on us. While ISG maintains cybersecurity insurance, the costs related to cybersecurity threats or service disruptions to both ISG and our clients may not be fully insured.

For more information regarding the risks we face from cybersecurity threats, see the risks identified under “Risks Related to Data, Cybersecurity and Confidential Information” found in “Part 1A, Risk Factors” of this Annual Report on Form 10-K.

Dividends to Shareholders

In May 2023, the Board of Directors approved quarterly dividends of $0.045 per share of ISG common stock. The Company expects to pay a total cash dividend of $0.18 per share for the four quarters ending June 2024. These dividends are funded through cash flow from operations, available cash on hand and/or borrowings under our revolving credit facility. We anticipate we will continue to pay regular quarterly dividends on our common stock for the foreseeable future, the declaration, timing and amounts of any such dividends remain subject to the discretion of our Board of Directors. During the fiscal quarter and fiscal year ended December 31, 2023, we paid dividends and dividend equivalents of $2.2 million and $8.7 million, respectively.

Issuer Purchases of Equity Securities

On August 1, 2023, the Board of Directors approved a new share repurchase authorization of an additional $25.0 million. The new share repurchase program will take effect upon completion of the Company’s current program, which had approximately $0.9 million remaining as of January 1, 2024. The Company had approximately $25.9 million in aggregate available under its share repurchase program as of December 31, 2023. The shares may be repurchased from time to time in open market transactions at prevailing market prices, in privately negotiated transactions, pursuant to a Rule 10b5-1 repurchase plan or by other means in accordance with federal securities laws. The timing and the amount of any repurchases will be determined by the Company’s management based on its evaluation of market conditions, capital allocation alternatives and other factors. There is no guarantee as to the number of shares that will be repurchased, and the repurchase program may be extended, suspended or discontinued at any time without notice at the Company’s discretion.

The following table details the repurchases that were made during the three months ended December 31, 2023.

BUSINESS OVERVIEW

Information Services Group, Inc. (Nasdaq: III) is a leading global technology research and advisory firm. A trusted business partner to over 900 clients, including more than 75 of the top 100 enterprises in our markets, ISG is committed to helping corporations, public sector organizations and service and technology providers achieve operational excellence and faster growth. The Company specializes in digital transformation services, including automation, cloud and data analytics; sourcing advisory; managed governance and risk services; network carrier services; technology strategy and operations design; change management; market intelligence and technology research and analysis. Founded in 2006, and based in Stamford, Connecticut, ISG employs over 1,500 digital-ready professionals operating in more than 20 countries—a global team known for its innovative thinking, market influence, deep industry and technology expertise and world-class research and analytical capabilities based on the industry’s most comprehensive marketplace data. For more information, visit www.isg-one.com.

Our strategy is to strengthen our existing market position and develop new services and products to support future growth plans. As a result, we are focused on growing our existing service model, expanding geographically, developing new industry sectors, productizing market data assets, expanding our managed services offerings and growing via acquisitions. Although we do not expect any adverse conditions that will impact our ability to execute against our strategy over the next twelve months, the more significant factors that could limit our ability to grow in these areas include global macro-economic conditions and the impact on the overall sourcing market, competition, our ability to retain advisors and reductions in discretionary spending with our top client accounts or other significant client events. Other areas that could impact the business would also include natural disasters, pandemics, wars, legislative and regulatory changes and capital market disruptions.

We principally derive revenues from fees for services generated on a project-by-project basis. Prior to the commencement of a project, we reach agreement with the client on rates for services based upon the scope of the project, staffing requirements and the level of client involvement. Revenues for services rendered are recognized on a time and materials basis or on a fixed-fee or capped-fee basis in accordance with accounting and disclosure requirements for revenue recognition.

Revenues for time and materials contracts are recognized based on the number of hours worked by our advisors at an agreed upon rate per hour and are recognized in the period in which services are performed. Revenues for time and materials contracts are billed monthly, semimonthly or in accordance with the specific contractual terms of each project.

We also derive our revenues from certain recurring revenue streams. These include such annuity-based ISG offerings as ISG GovernX, Research, Software as a Subscription (Automation licenses), ISG Inform and the multi-year Public Sector contracts. These offerings are characterized by subscriptions (i.e., renewal-centric as opposed to project-centric revenue streams) or, in some instances, multi-year contracts. Our digital services now span a volume of offerings and have become embedded as part of our traditional transaction services. Digital enablement provides capabilities, digital insights and better engagement with clients and partners.

Our results are impacted principally by our full-time consultants’ utilization rate, the number of business days in each quarter and the number of our revenue-generating professionals who are available to work. Our utilization rate can be negatively affected by increased hiring because there is generally a transition period for new professionals that result in a temporary drop in our utilization rate. Our utilization rate can also be affected by seasonal variations in the demand for our services from our clients. The number of business workdays is also affected by the number of vacation days taken by our consultants and holidays in each quarter. We typically have fewer business workdays available in the fourth quarter of the year, which can impact revenues during that period. Time-and-expense engagements do not provide us with a high degree of predictability as to performance in future periods. Unexpected changes in the demand for our services can result in significant variations in utilization and revenues and present a challenge to optimal hiring and staffing. The volume of work performed for any particular client can vary widely from period to period.

CURRENT ENVIRONMENT

Inflation rates and the adverse effect of interest rates 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. Our exposure from changes to interest rates has impacted our business operations, financial performance and results of operations, as our interest expense has increased from $3.2 million in 2022 to $6.2 million in 2023. The Company continuously monitors these changes and evaluates any effect. 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.

EXECUTIVE SUMMARY

2023 was a largely successful year for ISG. We delivered another year of record revenues, at $291 million. A strong first nine months of the year was followed by a soft fourth quarter, due to lingering macro concerns that impacted demand for advisory services in the short term. Given that the overall IT and business services industry was down 6 percent for the year, we consider our topline growth of 2 percent to be a solid performance.

Our investments in our recurring-revenue businesses continue to pay off. For the year, we generated record recurring revenues of $125 million, up 16 percent, driven by our research and platforms businesses. Recurring revenue now represents 43 percent of our overall revenue, up 500 basis points from the prior year. This puts us on track to reach our previously announced target of $150 million in recurring revenues by the end of 2025.

Our profitability, as measured by adjusted EBITDA, was $38 million, down from the prior year. Even as discretionary spending on advisory services slowed in toward the end of the year, we decided to retain much of our advisory team globally in anticipation of a rebound in 2024, while investing in training more than 1,200 of our employees in AI technology during the fourth quarter.

We continue to expand our business for current and future growth—organically in areas like Cybersecurity, Training-as-a-Service (TaaS), and most recently Enterprise AI Advisory—and through acquisition, with our October purchase of Ventana Research.

A leading technology research business covering the $800 billion global software industry, Ventana Research gives us unmatched analyst coverage of software vendors—adding an important new pillar to our ISG Research portfolio and a strong complement to our Software Advisory business.

With this addition, ISG is increasing its recurring revenue streams, while gaining more than 40 unique new clients and adding nearly two dozen talented research professionals to our roster of world-class technology analysts.

Our acquisition of Ventana Research came one year to the day after we acquired Change 4 Growth, a leading change management firm, in 2022. C4G has proven to be an excellent complement to our existing Enterprise Change business, delivering double-digit growth in 2023.

ISG influences more than $200 billion in enterprise technology spending annually. We are using this market influence to lay the groundwork for the next big thing in technology: Artificial Intelligence, especially the most-talked-about technology development of our time—Generative AI.

Through our new Enterprise AI Advisory business, we are identifying use cases for this exciting new technology and demonstrating where the greatest opportunities lie for ROI. That includes advising clients on performance improvements in their IT operations and business processes and how to design for, buy, build, run and govern AI products, infrastructure and services.

Beyond AI, we are leveraging our global leadership in sourcing advisory to launch a platform solution called ISG Tango™ that puts our sourcing playbooks and intellectual property, contract exhibits, provider intelligence and other tools at the fingertips of our enterprise and provider clients and our advisors, to make the overall sourcing process more efficient and interactive.

ISG Tango™, we believe, will enable us to capture more unadvised transaction activity among the world’s largest enterprises (the G2000), and penetrate the underserved middle market, which spends an estimated $130 billion annually on technology and business services.

RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 2023 COMPARED TO YEAR ENDED DECEMBER 31, 2022

Revenues

Revenues are generally derived from fixed-fee contracts as well as engagements priced on a time and materials basis, which are recorded based on actual time worked as the services are performed. In addition, we also earn revenues which are contingent on the attainment of certain contractual milestones. Revenues related to materials required during an engagement (mainly out-of-pocket expenses such as airfare, lodging and meals) generally do not include a profit mark up and can be charged and reimbursed separately or as part of the overall fee arrangement. Invoices are issued to clients monthly, semimonthly or in accordance with the specific contractual terms of each project.

We operate in one segment, fact-based sourcing advisory services. We operate principally in the Americas, Europe and Asia Pacific. Our foreign operations are subject to local government regulations and to the uncertainties of the economic and political conditions of those areas, and the revenue for our foreign operations is predominantly invoiced and collected in local currency.

​

Geographical revenue information for the segment is as follows:

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Years Ended December 31, |
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | Percent |
Geographic Area |  | 2023 |  | 2022 |  | Change |  | Change |
​ | ​ | (in thousands) |
Americas | ​ | $ | 177,131 |  | $ | 166,661 |  | $ | 10,470 |  | 6 | %
Europe | ​ |  | 87,074 | ​ |  | 89,908 | ​ |  | (2,834) |  | (3) | %
Asia Pacific | ​ |  | 26,849 | ​ |  | 29,698 | ​ |  | (2,849) |  | (10) | %
Total revenues | ​ | $ | 291,054 | ​ | $ | 286,267 | ​ | $ | 4,787 |  | 2 | %

​

Revenues increased by $4.8 million or approximately 2% in 2023. The increase in revenue in the Americas was primarily attributable to an increase in our Consulting and Automation service lines. The slight decrease in revenue in Europe was primarily attributable to a decrease in our Advisory service line, partially offset by an increase in our Automation and Research service lines. The decrease in revenue in Asia Pacific was primarily attributable to a decrease in our Advisory and NaSa service lines, partially offset by an increase in our Research service line. The translation of foreign currency revenues into U.S. dollars was flat with a negative impact in Asia Pacific, being offset by a positive impact in Europe compared to the prior year.

Operating Expenses

The following table presents a breakdown of our operating expenses by functional category:

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | Years Ended December 31, |
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | Percent |
Operating Expenses |  |  | 2023 |  | 2022 |  | Change |  | Change |
​ | ​ | ​ | (in thousands) |
Direct costs and expenses for advisors |  | ​ | $ | 178,913 |  | $ | 169,650 |  | $ | 9,263 |  | 5 | %
Selling, general and administrative | ​ | ​ |  | 91,271 | ​ |  | 81,769 | ​ |  | 9,502 |  | 12 | %
Depreciation and amortization | ​ | ​ |  | 6,258 | ​ |  | 5,368 | ​ |  | 890 |  | 17 | %
Total operating expenses | ​ | ​ | $ | 276,442 | ​ | $ | 256,787 | ​ | $ | 19,655 |  | 8 | %

​

Total operating expenses increased by $19.7 million, or approximately 8%, in 2023. The increase in operating expenses was due primarily to higher bad debt expense of $5.1 million (refer to Note 2 for details), license fees of $5.0 million, contract labor of $3.0 million, restructuring costs of $1.9 million, travel and entertainment expenses of $1.7 million, non-cash stock based compensation of $1.7 million, computer expenses of $1.0 million, professional fees of $0.7 million and conference expenses of $0.5 million. The cost increases were partially offset by lower compensation expenses of $2.4 million.

Compensation costs consist of a mix of fixed and variable salaries, annual bonuses, benefits and retirement plan contributions. Statutory and 401(k) plans are offered to employees as appropriate. Direct costs also include employee taxes, health insurance, workers compensation and disability insurance.

27

Table of Contents

A portion of compensation expenses for certain billable employees are allocated between direct costs and selling, general and administrative costs based on relative time spent between billable and non-billable activities.

Selling costs consist principally of compensation expense related to business development, proposal preparation and delivery and negotiation of new client contracts. Selling costs also include travel expenses relating to the pursuit of sales opportunities, expenses for hosting periodic client conferences, public relations activities, participation in industry conferences, industry relations, website maintenance and business intelligence activities. Additionally, we maintain a dedicated global marketing function responsible for developing and managing sales campaigns, brand promotion, the ISG Index and assembling client proposals.

We maintain a comprehensive program for training and professional development with the related costs included in SG&A. Related expenses include product training, updates on new service offerings or methodologies and development of client project management skills. Also included in training and professional development are expenses associated with the development, enhancement and maintenance of our proprietary methodologies and tools and the systems that support them.

Selling, general and administrative expenses consist principally of executive management compensation, allocations of billable employee compensation related to general management activities, IT infrastructure and costs for finance, accounting, information technology and human resource functions. General and administrative costs also reflect continued investment associated with implementing and operating client and employee management systems. Because our billable personnel operate remotely or on client premises, all occupancy expenses are recorded as general and administrative.

Depreciation and amortization expenses in 2023 and 2022 were $6.3 million and $5.4 million, respectively. The increase of $0.9 million was primarily due to the acquisitions of Change 4 Growth and Ventana Research. See Note 4—Acquisition in the Notes to Consolidated Financial Statements for more regarding these acquisitions. Our fixed assets consist of furniture, fixtures, equipment (mainly personal computers) and leasehold improvements. Depreciation expenses are generally computed by applying the straight-line method over the estimated useful lives of assets. We also capitalize some costs associated with the purchase and development of internal-use software, system conversions and website development costs. These costs are amortized over the estimated useful life of the software or system.

We amortize our intangible assets (e.g., client relationships and databases) over their estimated useful lives. Goodwill related to acquisitions is not amortized but is subject to annual impairment testing.

Other Income (Expense), Net

The following table presents a breakdown of other expense, net:

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

Interest income |  | ​ | $ | 497 |  | $ | 189 |  | $ | 308 |  | 163 | %
Interest expense | ​ | ​ |  | (6,190) | ​ |  | (3,157) | ​ |  | (3,033) |  | (96) | %
Foreign currency transaction gain | ​ | ​ |  | (158) | ​ |  | 170 | ​ |  | (328) |  | (193) | %
Total other expense, net | ​ | ​ | $ | (5,851) | ​ | $ | (2,798) | ​ | $ | (3,053) |  | (109) | %

​

The total increase of $3.1 million was primarily the result of higher interest expense attributable to higher interest rates, our higher debt balance and $0.4 million associated with the write-off of deferred financing costs.

Income Tax Expense

Our effective tax rate varies from period to period based on the mix of earnings among the various state and foreign tax jurisdictions in which business is conducted and the level of non‑deductible expenses incurred in any given period. Our effective tax rate for the year ended December 31, 2023 was 29.8% compared to 26.1% for the year ended December 31, 2022. The variance from the U.S. statutory rate of 21.0% for the year ended December 31, 2023 was primarily caused by the impact of higher tax rates applicable on company earnings in foreign jurisdictions and non-deductible expenses for tax purposes in the United States.

NON-GAAP FINANCIAL PRESENTATION

This management’s discussion and analysis presents supplemental measures of our performance that are derived from our consolidated financial information but are not presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”). We refer to these financial measures, which are considered “non-GAAP financial measures” under SEC rules, as adjusted EBITDA, adjusted net income and adjusted earnings per diluted share, each as defined below. See “Non-GAAP Financial

28

Table of Contents

Measures” below for information about our use of these non-GAAP financial measures, including our reasons for including these measures and reconciliations of each non-GAAP financial measure to the most directly comparable GAAP financial measure.

NON-GAAP FINANCIAL MEASURES

We use non-GAAP financial measures to supplement the financial information presented on a GAAP basis. We provide adjusted EBITDA (defined as net income, plus interest, taxes, depreciation and amortization, foreign currency transaction gains/losses, non-cash stock compensation, interest accretion associated with contingent consideration, tax indemnity receivables, accounts receivables reserve, acquisition-related costs, and severance, integration and other expense), adjusted net income (defined as net income, plus amortization of intangible assets, non-cash stock compensation, foreign currency transaction gains/losses, interest accretion associated with contingent consideration, acquisition-related costs, accounts receivables reserves, write-off of deferred financing cost and severance, integration and other expense on a tax-adjusted basis) and adjusted net income per diluted share, excluding the net of tax effect of the items set forth in the table below. These are non-GAAP measures that the Company believes provide useful information to both management and investors by excluding certain expenses and financial implications of foreign currency translations that management believes are not indicative of ISG’s core operations. These non-GAAP measures are used by the Company to evaluate the Company’s business strategies and management’s performance. These non-GAAP financial measures exclude non-cash and certain other special charges that many investors believe may obscure the user’s overall understanding of the Company’s current financial performance and the Company’s prospects for the future. We believe that these non-GAAP measures provide useful information to investors because they improve the comparability of the financial results between periods and provide for greater transparency of key measures used to evaluate the Company’s performance.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity

Our primary sources of liquidity are cash flows from operations, existing cash and cash equivalents and borrowings under our revolving line of credit. Operating assets and liabilities consist primarily of accounts receivable and contract assets, prepaid expense and other assets, accounts payable, contract liabilities, accrued expenses and other liabilities. The volume of billings and timing of collections and payments affect these account balances.

The following table summarizes our cash flows for the years ended December 31, 2023, 2022 and 2021:

As of December 31, 2023, our liquidity and capital resources included cash, cash equivalents and restricted cash of $22.8 million compared to $30.7 million as of December 31, 2022, a net decrease of $7.9 million, which was primarily attributable to the following:

| ● | our operating activities provided net cash of $12.3 million for the year ended December 31, 2023. Net cash provided from operations was primarily attributable to our net income after adjustments for non-cash charges of approximately $25.5 million partially offset by $13.2 million use of working capital primarily attributable to a $6.7 million change in accounts receivables and contract assets, a $6.5 million change in prepaid expense and other assets, a $4.9 million change in accounts payables, partially offset by a $3.8 million change in accrued expenses and other liabilities; and $1.1 million change in contract liabilities;

| ● | treasury share repurchases of $3.5 million;

| ● | repayment of outstanding debt of $84.2 million;

| ● | payments related to tax withholding for stock-based compensation of $2.7 million;

| ● | cash dividends paid to shareholders of $8.7 million;

| ● | proceeds from revolving facility of $84.2 million;

| ● | payment of contingent consideration of $1.5 million;

| ● | payment for Ventana acquisition of $1.0 million:

Table of Contents

| ● | payments related to debt financing costs of $0.8 million;

| ● | capital expenditures for property, plant and equipment of $3.4 million; and

| ● | proceeds from issuance of employee stock purchase plan shares of $0.9 million.

Capital Resources

The Company’s current outstanding debt may limit our ability to fund general corporate requirements and obtain additional financing, impact our flexibility in responding to business opportunities and competitive developments and increase our vulnerability to adverse economic and industry conditions.

On February 22, 2023, the Company amended and restated its senior secured credit facility to increase the revolving commitments per the revolving facility (the “2023 Credit Agreement”) from $54.0 million to $140.0 million and eliminate its term loan. The material terms under the 2023 Credit Agreement are as follows. Capitalized terms used but not defined herein have the meanings ascribed to them in the 2023 Credit Agreement:

| ● | The revolving credit facility has a maturity date of February 22, 2028.

| ● | The credit facility is secured by all of the equity interests owned by the Company, and its direct and indirect domestic subsidiaries and, subject to agreed exceptions, the Company’s direct and indirect “first-tier” foreign subsidiaries, and a perfected first priority security interest in all of the Company’s and its direct and indirect domestic subsidiaries’ tangible and intangible assets.

| ● | The Company’s direct and indirect existing and future wholly owned domestic subsidiaries serve as guarantors to the Company’s obligations under the senior secured facility.

| ● | At the Company’s option, the credit facility bears interest at a rate per annum equal to either (i) the “Base Rate” (which is the highest of (a) the rate publicly announced from time to time by the administrative agent as its “prime rate,” (b) the Federal Funds Rate plus 0.5% per annum and (c) Term SOFR, plus 1.0%), plus the applicable margin (as defined below) or (ii) Term SOFR (which is the Term SOFR screen rate for the relevant interest period plus a credit spread adjustment of 0.10%) as determined by the administrative agent, plus the applicable margin. The applicable margin is adjusted quarterly based upon the Company’s consolidated leverage ratio. Prior to the end of the first quarter-end following the closing of the credit facility, the applicable margin shall be a percentage per annum equal to 0.50% for the revolving loans maintained as Base Rate loans or 1.50% for the revolving loans maintained as Term SOFR loans.

| ● | The senior secured credit facility contains a number of covenants that, among other things, place restrictions on matters customarily restricted in senior secured credit facilities, including restrictions on indebtedness (including guarantee obligations), liens, fundamental changes, sales or dispositions of property or assets, investments (including loans, advances, guarantees and acquisitions), transactions with affiliates, dividends and other payments in respect of capital stock, optional payments and modifications of other material debt instruments, negative pledges and agreements restricting subsidiary distributions and changes in line of business. In addition, the Company is required to comply with a consolidated leverage ratio and consolidated interest coverage ratio.

| ● | The senior secured credit facility contains customary events of default, including cross-default to other material agreements, judgment default and change of control.

The Company’s financial statements include outstanding borrowings of $79.2 million both as of December 31, 2023 and December 31, 2022, which are carried at amortized cost. The fair value of debt is classified within Level 3 of the fair value hierarchy. The fair value of the Company's outstanding borrowings is approximately $79.8 million and $76.5 million as of December 31, 2023 and December 31, 2022, respectively. The fair values of debt have been estimated using a discounted cash flow analysis based on the Company's incremental borrowing rate for similar borrowing arrangements. The incremental borrowing rate used to discount future cash flows was 6.9% and 6.3% for December 31, 2023 and December 31, 2022, respectively. The Company also considered recent transactions of peer group companies for similar instruments with comparable terms and maturities as well as an analysis of current market conditions and interest rates. In the third quarter of 2023, the Company borrowed $5.0 million against the revolver and subsequently repaid $5.0 million during that quarter. The Company is currently in compliance with its financial covenants.

​

We anticipate that our current cash and the ongoing cash flows from our operations will be adequate to meet our working capital, capital expenditure and debt financing needs for at least the next twelve months. The anticipated cash needs of our business could change significantly if we pursue and complete additional business acquisitions, if our business plans change, if economic conditions change from

31

Table of Contents

those currently prevailing or from those now anticipated, or if other unexpected circumstances arise that may have a material effect on the cash flow or profitability of our business. If we require additional capital resources to grow our business, either internally or through acquisition, or maintain liquidity, we may seek to sell additional equity securities or to secure additional debt financing. The sale of additional equity securities or certain forms of debt financing could result in additional dilution to our stockholders. We may not be able to obtain financing arrangements in amounts or on terms acceptable to us in the future.

The Company has financial covenants underlying its debt which require a debt to adjusted EBITDA ratio of 3.25. The Company was in compliance with its financial covenants under the 2023 Credit Agreement as of December 31, 2023.

Employee Retirement Plans

For the fiscal years ended December 31, 2023 and 2022, we contributed $0.0 million and $2.1 million, respectively, to our 401(k) plan (the “Savings Plan”) on a fully discretionary basis. These amounts were invested by the participants in a variety of investment options under an arrangement with a third-party asset manager. All current and future financial risks associated with the gains and losses on investments are borne by Savings Plan participants.

Critical Accounting Policies and Estimates

The preparation of consolidated financial statements in conformity with generally accepted accounting principles requires the appropriate application of certain accounting policies, many of which require management to make estimates and assumptions about future events and their impact on amounts reported in our consolidated financial statements and related notes. Since future events and their impact cannot be determined with certainty, the actual results may differ from estimates. Such differences may be material to the consolidated financial statements.

We believe the application of accounting policies, and the estimates inherently required therein, are reasonable. These accounting policies and estimates are periodically reevaluated, and adjustments are made when facts and circumstances dictate a change. Historically, we have found the application of accounting policies to be appropriate, and actual results have not differed materially from those determined using necessary estimates.

Our accounting policies are more fully described in Note 2—Summary of Significant Accounting Policies in the Notes to Consolidated Financial Statements. We have identified revenue recognition as a critical accounting estimate:

Revenue Recognition

We recognize our revenues by applying the following five steps: (1) identifying the contract with the customer; (2) identifying the performance obligation(s) in the contract; (3) determining the transaction price; (4) allocating the transaction price to the performance obligation(s); and (5) recognizing revenue when (or as) the Company satisfies the performance obligation(s).

We principally derive revenues from fees for services generated on a project-by-project basis. Prior to the commencement of a project, we reach agreement with the client on rates for services based upon the scope of the project, staffing requirements and the level of client involvement. It is our policy to obtain written agreements from clients prior to performing services or when evidence of enforceable rights and obligations is obtained. In these agreements, the clients acknowledge that they will pay based upon the amount of time spent on the project or an agreed upon fee structure.

Revenues for time and materials contracts, which may include capped-fees or “not-to-exceed” clauses, are recognized based on the number of hours worked by our advisors at an agreed-upon rate per hour and are recognized in the period in which services are performed. Revenues for time and materials contracts are billed monthly, semimonthly or in accordance with the specific contractual terms of each project. For contracts with capped fees or not-to-exceed clauses, we monitor our performance and fees billed to ensure that revenue is not recognized in excess of the contractually capped fee.

Revenues related to fixed-fee contracts are recognized as value is delivered to the customer, consistent with the transfer of control to the customer over time. Revenue for these contracts is recognized proportionally over the term of the contract using an input method based on the proportion of labor hours incurred as compared to the total estimated labor hours for the fixed-fee contract performance obligations, which we consider the best available indicator of the pattern and timing in which contract performance obligations are fulfilled and control transfers to the customer. This percentage is multiplied by the contracted dollar amount of the project to determine the amount of revenue to recognize in an accounting period. The contracted amount used in this calculation typically excludes the amount the client pays for reimbursable expenses. There are situations where the number of hours to complete projects may exceed our original estimate as a result of an increase in project scope or unforeseen events. The results of any revisions in these estimates are reflected in the period in which they become known.

32

Table of Contents

For managed service implementation contracts, revenue is recognized over time as a percentage of hours incurred to date as compared to the total expected hours of the implementation, consistent with the transfer of control to the customer. For ongoing managed services contract, revenue is recognized over time, consistent with the weekly or monthly fee specified within such arrangements.

We also derive revenues based on negotiating reductions in network and software costs of companies with the entities’ related service providers and providing other services such as audits of network and communication expenses and consultation for network architecture. These contracts can be fixed in fees or can be based on the level of savings achieved related to its communications costs. Additionally, these contracts can also have a fixed component and a contingent component that is based on the savings generated by the Company. For network and software contingency contracts with termination for convenience clauses, revenue is recognized over time due to the existence of provisions for payment for progress incurred to date plus a reasonable profit margin. The contract periods range from a few months to in excess of a year.

We also enter into arrangements for the sale of automation software licenses and related delivery of consulting or implementation services at the same time or within close proximity to one another. Such software-related performance obligations include the sale of on-premise software, hybrid and software-as-a-service licenses, as well as other software-related services. Revenue associated with the software performance obligation is primarily recognized at the point at which the software is installed or access is granted.

Revenue associated with events is recognized at the point of time at which the event occurs and is primarily comprised of sponsorships. Conversely, revenue associated with research subscriptions is recognized over time, as the customer accesses our data or related platforms. In addition, we sell research products for which the revenue is recognized at a point in time upon delivery to the client.

The agreements entered into in connection with a project typically allow our clients to terminate early due to breach or for convenience with 30 days’ notice. In the event of termination, the client is contractually required to pay for all time, materials and expenses incurred by us through the effective date of the termination. In addition, from time to time, we enter into agreements with clients that limit our right to enter into business relationships with specific competitors of that client for a specific time period. These provisions typically prohibit us from performing a defined range of services that we might otherwise be willing to perform for potential clients. These provisions are generally limited to six to twelve months and usually apply only to specific employees or the specific project team.

When we recognize revenues in advance of billing, those revenues are recorded as contract assets. When we invoice in advance of earning revenues, those amounts are recorded as contract liabilities.

Recent Accounting Pronouncements

See Note 2 to our consolidated financial statements included elsewhere in this report.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to financial market risks primarily related to changes in interest rates. A 100 basis point change in interest rates would result in an annual change in the results of operations of $0.8 million pre‑tax. We do not enter into investments for trading or speculative purposes.

​

Interest Rate Risk

​

As of December 31, 2023, the Company had $79.2 million in total debt principal outstanding. Note 12 — Financing Arrangements and Long-Term Debt in the Notes to Consolidated Financial Statements provides additional information regarding the Company’s outstanding debt obligations.

​

All of the Company’s total debt outstanding as of December 31, 2023 was based on a floating base rate (SOFR – Secured Overnight Financing Rate) of interest, which potentially exposes the Company to increases in interest rates. However, due to our debt to EBITDA ratio of 2.4 times and forecasted rates from external banks, we believe that our total exposure is limited and is considered in our forecasted cash uses.

​

Foreign Currency Risk

​

A significant portion of our revenues are typically derived from sales outside of the United States. Among the major foreign currencies in which we conduct business are the Euro, the British Pound and the Australian dollar. The reporting currency of our consolidated financial statements is the U.S. dollar. As the values of the foreign currencies in which we operate fluctuate over time relative to the U.S. dollar, the Company is exposed to both foreign currency translation and transaction risk.

​

Translation risk arises as our foreign currency assets and liabilities are translated into U.S. dollars because the functional currencies of our foreign operations are generally denominated in the local currency. Adjustments resulting from the translation of these assets and

33

Table of Contents

liabilities are deferred and recorded as a component of stockholders’ equity. In 2023, the impact of foreign currency translation on our Statement of Stockholders’ Equity was $0.7 million. The translation of our foreign currency revenues and expenses historically has not had a material impact on our consolidated earnings because movements in and among the major currencies in which we operate tend to impact our revenues and expenses fairly equally. However, our earnings could be impacted during periods of significant exchange rate volatility, or when some or all of the major currencies in which we operate move in the same direction against the U.S. dollar.

​

Transaction risk arises when we enter into a transaction that is denominated in a currency that may differ from the local functional currency. As these transactions are translated into the local functional currency, a gain or loss may result, which is recorded in current period earnings. In 2023, the impact on revenues from foreign currency transactions was not material to our condensed consolidated financial statements.

​

Credit Risk

​

Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of short-term, highly liquid investments classified as cash equivalents and accounts receivable and contract assets. The majority of the Company’s cash and cash equivalents are with large investment-grade commercial banks. Accounts receivable and contract assets balances deemed to be collectible from customers have limited concentration of credit risk due to our diverse customer base and geographies.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports that we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2023, as required by Rule 13a-15(b) under the Exchange Act. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of December 31, 2023.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Exchange Act. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements for external reporting purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2023, as required by Rule 13a-15(c) under the Exchange Act. In making this assessment, we used the criteria set forth in the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on its evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2023.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2023 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in its attestation report which appears herein.

Table of Contents

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on the Effectiveness of Controls

Our management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in a cost-effective control system, no controls can provide absolute assurance that misstatements due to error or fraud will not occur, and no evaluation of any such controls can provide absolute assurance that control issues and instances of fraud, if any, within our Company have been detected.

These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of the effectiveness of our controls to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies and procedures.

Item 9B. Other Information

During the three months ended December 31, 2023, none of the Company’s directors or officers adopted, modified or terminated a Rule 10b5-1 trading arrangement or a non-Rule 10b5-1 trading arrangement (each as defined in Item 408 of Regulation S-K under the Exchange Act).

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Information Services Group, Inc. and its subsidiaries (the “Company”) as of December 31, 2023 and 2022, and the related consolidated statements of income and comprehensive income, of stockholders’ equity and of cash flows for each of the three years in the period ended December 31, 2023, including the related notes and financial statement schedule listed in the index appearing under Item 15(a)(2) (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

F-1

Table of Contents

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue Recognition – Estimated Labor Hours to Complete Fixed Fee Contract Performance Obligations

As described in Note 2 to the consolidated financial statements, revenues related to fixed fee contracts are recognized as value is delivered to the customer, consistent with the transfer of control to the customer over time. Revenue for these contracts is recognized proportionally over the term of the contract using an input method based on the proportion of labor hours incurred as compared to the total estimated labor hours for the fixed fee contract performance obligations, which management considers to be the best available indicator of the pattern and timing in which contract performance obligations are fulfilled and control transfers to the customer. This percentage is multiplied by the contracted dollar amount of the project to determine the amount of revenue to recognize in an accounting period. Revenue related to fixed fee contracts is a portion of the Company’s total revenue of $291 million for the year ended December 31, 2023.

The principal considerations for our determination that performing procedures relating to revenue recognition – estimated labor hours to complete fixed fee contract performance obligations is a critical audit matter are the significant judgment by management when developing the total estimated labor hours to complete fixed fee contract performance obligations used to determine the amount of revenue to recognize, which in turn led to a high degree of auditor judgment, subjectivity, and effort in performing procedures to evaluate the total estimated labor hours to complete performance obligations used in revenue recognition for fixed fee contracts.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the revenue recognition process, including controls over the determination of total estimated labor hours to complete fixed fee contract performance obligations. The procedures also included, among others, (i) evaluating management’s process for determining the total estimate of labor hours to complete performance obligations; (ii) evaluating the reasonableness of estimated labor hours used by management for a sample of fixed fee contracts; (iii) testing actual hours incurred and recalculating the revenue recognized to date for a sample of fixed fee contracts; and (iv) considering the factors that can affect the accuracy of estimated labor hours for a sample of fixed fee contracts. Evaluating the revenue recognition for fixed fee contracts involved assessing management’s ability to reasonably estimate labor hours to complete the performance obligations by performing a comparison of the original estimated and actual hours incurred on similar completed fixed fee contracts.

(tabular amounts in thousands, except per share data)

​

NOTE 1—DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIO NS

Information Services Group, Inc. (the “Company”, or “ISG”) was founded in 2006 with the strategic vision to become a high-growth, leading provider of information-based advisory services. The Company specializes in digital transformation services, including automation, cloud and data analytics; sourcing advisory; managed governance and risk services; network carrier services; technology strategy and operations design; change management; market intelligence and technology research and analysis.

NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Principles of Consolidation

​

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. These consolidated financial statements and footnotes are presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All intercompany accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, references to the Company include ISG and its consolidated subsidiaries.

​

​

Use of Estimates

​

​

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the periods reported. Actual results may differ from those estimates. The complexity of the estimation process and issues related to the assumptions, risks and uncertainties inherent in the application of the revenue recognition guidance for contracts in which control is transferred to the customer over time affect the amounts of revenues, expenses, contract assets and contract liabilities. Numerous internal and external factors can affect estimates. Estimates are also used for but not limited to allowance for doubtful accounts, useful lives of furniture, fixtures and equipment and definite lived intangible assets, depreciation expense, fair value assumptions in evaluating goodwill for impairment, income taxes and deferred tax asset valuation and the valuation of stock-based compensation.

Business Combinations

​

​

We have acquired businesses critical to the Company’s long-term growth strategy. Results of operations for acquisitions are included in the accompanying consolidated statement of comprehensive income from the date of acquisition. Acquisitions are accounted for using the purchase method of accounting and the purchase price is allocated to the net assets acquired based upon their estimated fair values at the date of acquisition. The excess of the purchase price over the net assets is recorded as goodwill. Acquisition-related costs are expensed as incurred and recorded in selling, general and administrative expenses.

​

Cash and Cash Equivalents

The Company considers all highly liquid instruments with an original maturity of three months or less to be cash equivalents, including certain money market accounts. The Company principally maintains its cash in money market and bank deposit accounts in the United States of America, which typically exceed applicable insurance limits. The Company believes it is not exposed to any significant credit risk on cash and cash equivalents.

​

Restricted Cash

​

Restricted cash consists of cash and cash equivalents which the Company has committed for rent deposits and are not available for general corporate purposes.

​

Accounts Receivable, Contract Assets and Allowance for Doubtful Accounts

Our trade receivables primarily consist of amounts due for services already performed. The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of clients to pay fees or for disputes that affect its ability to fully collect billed accounts receivable. The allowance for these risks is prepared by reviewing the status of all accounts and recording reserves on a specific identification method based on previous experiences and historical bad debts. However, our actual experience may vary from these estimates. If the financial condition of our clients were to deteriorate, resulting in their inability or unwillingness to pay their invoices, we

(tabular amounts in thousands, except per share data)

​

may need to record additional allowances or write-offs in future periods. To the extent the provision relates to a client’s inability or unwillingness to make required payments, the provision is recorded as bad debt expense, which is classified within selling, general and administrative expense in the accompanying consolidated statement of comprehensive income. Historically, the Company’s bad debt reserves and write-offs have not been significant.

​

The provision for unbilled services is recorded as a bad debt expense to the extent the provision relates to fee adjustments and other discretionary pricing adjustments. Historically, the Company’s unbilled receivable reserves and write-offs have not been significant.

During the fourth quarter of 2023, a client that had engaged us for two multi-year projects, which previously commenced in 2021 and 2022, failed to make payments as per the contracted payment schedule and we ceased performing services under the agreements. After unsuccessful negotiations, we provided the client with notice that we would be terminating the respective projects. Accordingly, during the fourth quarter of 2023, the Company recorded through bad debt expense an allowance for doubtful accounts reserve of $4.8 million associated with this client. The specific reserve recorded as of December 31, 2023 represents management' s best estimate of the probable amount of collection related to the outstanding amounts under these agreements. In the event that collection efforts prove unsuccessful, the Company may seek payment through other means, including legal action. Actual collections from the client may differ from the Company's estimate.

​

​

Prepaid Expenses and Other Current Assets

​

Prepaid expenses and other current assets consist primarily of prepaid expenses for insurance, conferences, deposits for facilities, programs, software and promotion items.

​

Furniture, Fixtures and Equipment, net

​

Furniture, fixtures and equipment are recorded at cost. Depreciation is computed by applying the straight-line method over the estimated useful life of the assets, which ranges from two to five years. Leasehold improvements are depreciated over the lesser of the useful life of the underlying asset or the lease term, which generally ranges from two to five years. Repairs and maintenance are charged to expense as incurred. The cost and accumulated depreciation of assets sold or otherwise disposed of are removed from the accounts and any associated gain or loss thereon is reflected in the accompanying consolidated statement of comprehensive income.

The Company capitalizes internal-use software and website development costs and records these amounts within Furniture, Fixtures and Equipment, net. Accounting standards require that certain costs related to the development or purchase of internal-use software and systems as well as the costs incurred in the application development stage related to its website be capitalized and amortized over the estimated useful life of the software or system. They also require that costs related to the preliminary project stage, data conversion and post implementation/operation stage of an internal-use software development project be expensed as incurred.

​

​

During the years ended December 31, 2023, 2022 and 2021 the Company capitalized $1.7 million, $1.7 million and $0.8 million, respectively, of costs associated with system and website development.

​

Goodwill

Our goodwill represents the excess of the cost of businesses acquired over the fair value of the net assets acquired at the date of acquisition. Goodwill is not amortized but rather tested for impairment at least annually in accordance with accounting and disclosure requirements for goodwill and other indefinite-lived intangible assets. This test is performed by us during our fourth fiscal quarter or more frequently if we believe impairment indicators are present.

A qualitative assessment is performed to determine whether the existence of events or circumstances leads to a determination that it is more likely than not the fair value of the reporting unit is less than its carrying amount. If, based on the evaluation, it is determined to be more likely than not that the fair value is less than the carrying value then goodwill is tested further for impairment. If the fair value of goodwill is lower than its carrying amount, an impairment loss is recognized in an amount equal to the difference. Subsequent increases in value are not recognized in the financial statements.

​

(tabular amounts in thousands, except per share data)

​

There was no impairment of goodwill during the years ended December 31, 2023, 2022 and 2021. There were no indicators identified in 2023, 2022 or 2021 that would suggest that it is more likely than not that the Company’s reporting unit is impaired.

Long-Lived Assets

Long-lived assets, excluding goodwill and indefinite-lived intangibles, to be held and used by the Company are reviewed to determine whether any significant change in the long-lived asset’s physical condition, a change in industry conditions or a reduction in cash flows associated with the asset group that contains the long-lived asset. If these or other factors indicate the carrying amount of the asset group, which is the lowest level for which identifiable cash flows exist that are separately identifiable from other cash flows, may not be recoverable, the Company determines whether impairment has occurred through the use of an undiscounted cash flow analysis. If impairment has occurred, the Company recognizes a loss for the difference between the carrying amount and the fair value of the asset group. The fair value of the asset group is measured using market prices or, in the absence of market prices, an estimate of discounted cash flows. Cash flows are generally discounted at an interest rate commensurate with our weighted average cost of capital. Assets are classified as held for sale when the Company has a plan for disposal of certain assets and those assets meet the held for sale criteria.

​

Debt Issuance Costs

​

Costs directly incurred in obtaining long-term financing, typically bank and attorney fees, are deferred and are amortized over the life of the related loan. Deferred issuance costs are classified as a direct deduction to the long-term debt in the accompanying consolidated balance sheet. Amortization of debt issuance costs is included in interest expense and totaled $0.2 million, $0.3 million and $0.4 million for the years ended December 31, 2023, 2022 and 2021, respectively.

Revenue Recognition

We recognize our revenues by applying the following five steps: (1) identifying the contract with the customer; (2) identifying the performance obligation(s) in the contract; (3) determining the transaction price; (4) allocating the transaction price to the performance obligation(s); and (5) recognizing revenue when (or as) the Company satisfies the performance obligation(s).

We principally derive revenues from fees for services generated on a project-by-project basis. Prior to the commencement of a project, we reach agreement with the client on rates for services based upon the scope of the project, staffing requirements and the level of client involvement. It is our policy to obtain written agreements from clients prior to performing services or when evidence of enforceable rights and obligations is obtained. In these agreements, the clients acknowledge that they will pay based upon the amount of time spent on the project or an agreed upon fee structure.

Revenues for time and materials contracts, which may include capped fees or “not-to-exceed” clauses, are recognized based on the number of hours worked by our advisors at an agreed upon rate per hour and are recognized in the period in which services are performed. Revenues for time and materials contracts are billed monthly, semimonthly or in accordance with the specific contractual terms of each project. For contracts with capped fees or not-to-exceed clauses, we monitor our performance and fees billed to ensure that revenue is not recognized in excess of the contractually capped fee.

Revenues related to fixed-fee contracts are recognized as value is delivered to the customer, consistent with the transfer of control to the customer over time. Revenue for these contracts is recognized proportionally over the term of the contract using an input method based on the proportion of labor hours incurred as compared to the total estimated labor hours for the fixed-fee contract performance obligations, which we consider the best available indicator of the pattern and timing in which contract performance obligations are fulfilled and control transfers to the customer. This percentage is multiplied by the contracted dollar amount of the project to determine the amount of revenue to recognize in an accounting period. The contracted amount used in this calculation typically excludes the amount the client pays for reimbursable expenses. There are situations where the number of hours to complete projects may exceed our original estimate as a result of an increase in project scope or unforeseen events. The results of any revisions in these estimates are reflected in the period in which they become known.

For managed service implementation contracts, revenue is recognized over time as a percentage of hours incurred to date as compared to the total expected hours of the implementation, consistent with the transfer of control to the customer. For ongoing managed services contract, revenue is recognized over time, consistent with the weekly or monthly fee specified within such arrangements.

​

We also derive revenues based on negotiating reductions in network and software costs of companies with the entity’s related service providers and providing other services such as audits of network and communication expenses and consultation for network architecture. These contracts can be fixed in fees or can be based on the level of savings achieved related to its communications costs. Additionally, these contracts can also have a fixed component and a contingent component that is based on the savings generated by the Company. For network and software contingency contracts with termination for convenience clauses, revenue is recognized over time due to the existence of provisions for payment for progress incurred to date plus a reasonable profit margin. The contract periods range from a few months to in excess of a year.

We also enter into arrangements for the sale of automation software licenses and related delivery of consulting or implementation services at the same time or within close proximity to one another. Such software-related performance obligations include the sale of on-premise software, hybrid and software-as-a-service licenses, as well as other software-related services. Revenue associated with the software performance obligation is primarily recognized at the point at which the software is installed or access is granted.

Revenue associated with events is recognized at the point of time at which the event occurs and is primarily comprised of sponsorships. Conversely, revenue associated with research subscriptions is recognized over time, as the customer accesses our data or related platforms. In addition, we sell research products for which the revenue is recognized at a point in time upon delivery to the client.

The agreements entered into in connection with a project typically allow our clients to terminate early due to breach or for convenience with 30 days’ notice. In the event of termination, the client is contractually required to pay for all time, materials and expenses incurred by us through the effective date of the termination. In addition, from time to time, we enter into agreements with clients that limit our right to enter into business relationships with specific competitors of that client for a specific time period. These provisions typically prohibit us from performing a defined range of services that we might otherwise be willing to perform for potential clients. These provisions are generally limited to six to twelve months and usually apply only to specific employees or the specific project team.

When we recognize revenues in advance of billing, those revenues are recorded as contract assets. When we invoice in advance of completing services or earning revenues, those amounts are recorded as contract liabilities.

Reimbursable Expenditures

​

Amounts billed to customers for reimbursable expenditures are included in revenues and the associated costs incurred by the Company are included in direct costs and expenses for advisors in the accompanying consolidated statement of comprehensive income. Non-reimbursable amounts are expensed as incurred. Reimbursable expenditures totaled $1.5 million $0.8 million and $0.3 million for the years ended December 31, 2023, 2022 and 2021, respectively. The increase was attributable to pandemic-related travel restrictions being lifted and attending more in person meetings with clients to drive revenue.

​

Direct Costs and Expenses for Advisors

Direct costs and expenses for advisors include payroll expenses and advisory fees directly associated with the generation of revenues and other program expenses. Direct costs and expenses for advisors are expensed as incurred.

​

Direct costs and expenses for advisors also include expense accruals for discretionary bonus payments. Bonus accrual levels are adjusted throughout the year based on actual and projected Company performance.

​

Stock-Based Compensation

We grant restricted stock units with a fair value that is determined based on the closing price of our common stock on the date of grant. Such grants generally vest ratably over a two-to-four-year period for employees and a three-year period for directors. Stock-based compensation expense is recognized ratably over the applicable service period.

We follow the provisions of accounting and disclosure requirements for share-based payments, including the measurement and recognition of all share-based compensation under the fair value method.

​

Concentration of Credit Risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and accounts receivable. The Company places its cash investments with high-quality financial institutions. The Company extends credit to its customers based upon an evaluation of the customer’s financial condition and credit history and generally does not require collateral.

​

Treasury Stock

The Company makes treasury stock purchases in the open market pursuant to the share repurchase program, which was most recently approved by the Board of Directors on August 1, 2023.

​

Treasury stock is recorded on the consolidated balance sheet at cost as a reduction of stockholders’ equity. Shares are released from Treasury at original cost on a first-in, first-out basis, with any gain or loss on the sale reflected as an adjustment to additional paid-in capital.

The assets and liabilities of the Company’s foreign subsidiaries are translated into U.S. dollars at exchange rates in effect at the end of the reporting period. Revenue and expense items are translated at average exchange rates for the reporting period. Resulting translation adjustments are included in the accompanying statement of comprehensive income and accompanying statement of stockholders’ equity as a component of Accumulated Other Comprehensive Loss.

​

The functional currency of the Company and its subsidiaries is the respective local currency. The Company has contracts denominated in foreign currencies, and therefore a portion of the Company’s revenues are subject to foreign currency risks. Transactional currency gains and losses that arise from transactions denominated in currencies other than the functional currencies of our operations are recorded in Foreign Currency Translation in the accompanying consolidated statement of comprehensive income.

​

Fair Value of Financial Instruments

The carrying value of the Company’s cash and cash equivalents, receivables, accounts payable, other current liabilities and accrued interest approximate fair value.

Fair value measurements were applied with respect to our nonfinancial assets and liabilities measured on a nonrecurring basis, which would consist of measurements primarily to goodwill, intangible assets and other long-lived assets and assets acquired and liabilities assumed in a business combination.

Fair value is the price that would be received upon a sale of an asset or paid upon a transfer of a liability in an orderly transaction between market participants at the measurement date (exit price). Market participants can use market data or assumptions in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market-corroborated or generally unobservable. The use of unobservable inputs is intended to allow for fair value determinations in situations where there is little, if any, market activity for the asset or liability at the measurement date. Under the fair-value hierarchy:

● Level 1 measurements include unadjusted quoted market prices for identical assets or liabilities in an active market;

● Level 2 measurements include quoted market prices for identical assets or liabilities in an active market that have been adjusted for items such as effects of restrictions for transferability and those that are not quoted but are observable through corroboration with observable market data, including quoted market prices for similar assets; and

● Level 3 measurements include those that are unobservable and of a highly subjective measure.

During 2023, there were no transfers of our financial assets between Level 1, Level 2 or Level 3 measures. Our financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

The fair value measurement of contingent consideration is classified within Level 3 of the fair value hierarchy and reflects the Company’s own assumptions in measuring fair values using the income approach. In developing these estimates, the Company considered certain performance projections, historical results and industry trends. This amount was estimated through a valuation model that incorporated probability-weighted assumptions related to the achievement of these milestones and the likelihood of the Company making payments. These cash outflow projections have then been discounted using a rate of 4.9% and 2.5% for December 31, 2023, and 2022, respectively.

​

The Company’s financial instruments include outstanding borrowings of $79.2 million both as of December 31, 2023 and December 31, 2022, which are carried at amortized cost. The fair value of debt is classified within Level 3 of the fair value hierarchy. The fair value of the Company’s outstanding borrowings was approximately $79.8 million and $76.5 million at December 31, 2023 and December 31, 2022, respectively. The fair values of debt have been estimated using a discounted cash flow analysis based on the Company's incremental borrowing rate for similar borrowing arrangements. The incremental borrowing rate used to discount future cash flows was 6.9% and 6.3% for December 31, 2023 and 2022, respectively. The Company also considered recent transactions of peer group companies for similar instruments with comparable terms and maturities as well as an analysis of current market conditions and interest rates. In the third quarter of 2023, the Company borrowed $5.0 million against the revolver and subsequently repaid $5.0 million during that quarter. The Company is currently in compliance with its financial covenants.

Income Taxes

We use the asset and liability method to account for income taxes, including recognition of deferred tax assets and liabilities for the anticipated future tax consequences attributable to differences between financial statement amounts and their respective tax basis. We review our deferred tax assets for recovery. A valuation allowance is established when we believe that it is more likely than not that some portion of its deferred tax assets will not be realized. Changes in the valuation allowance from period to period are included in our tax provision in the period of change.

For uncertain tax positions, we use the prescribed model for assessing the financial recognition and measurement of all tax positions taken or expected to be taken in tax returns. This guidance provides clarification on derecognition, classification, interest and penalties, accounting in interim periods, disclosures and transition. Our provision for income taxes also includes the impact of provisions established for uncertain income tax positions, as well as the related interest.

Recently Issued Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (FASB) issued new guidance on the measurement of credit losses for financial assets measured at amortized cost, which includes accounts receivable and contract assets, and available for sale debt securities. The new guidance replaces the existing incurred loss impairment model with an expected loss methodology, which will result in more timely recognition of credit losses and additional disclosures. We adopted this standard using the modified retrospective approach with an effective date of January 1, 2023. The Company recognized a cumulative effect adjustment increasing accumulated deficit and increasing the allowance for credit losses by $0.1 million.

​

NOTE 3—REVENUE

The majority of our revenue is derived from contracts that can span from a few months to several years. We enter into contracts that can include various combinations of services, which, depending on contract type, are sometimes capable of being distinct. If services are determined to be distinct, they are accounted for as separate performance obligations. A performance obligation is a promise in a contract to transfer a distinct good or service to the client and is the unit of account. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The majority of our contracts have a single performance obligation as the promise to transfer the individual services is not separately identifiable from other promises in the contracts and, therefore, is not distinct. For contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation using our best estimate of the standalone selling price, or SSP, of each distinct product or service in the contract. The Company establishes SSP based on management’s estimated selling price or observable prices of products or services sold separately in comparable circumstances to similar clients.

Our contracts may include promises to transfer multiple services and products to a client. Determining whether services and products are considered distinct performance obligations that should be accounted for separately versus together may require judgment.

Contract Balances

The timing of revenue recognition, billings and cash collections result in billed accounts receivables, unbilled receivables (contract assets) and customer advances and deposits (contract liabilities). Our clients are billed based on the type of arrangement. A portion of our services is billed monthly based on hourly or daily rates. There are also client engagements in which we bill a fixed amount for our services. This may be one single amount covering the whole engagement or several amounts for various phases, functions, or milestones. Generally,

​

billing occurs subsequent to revenue recognition, resulting in contract assets. However, we sometimes receive advances or deposits before revenue is recognized, resulting in contract liabilities. Contract assets and liabilities are generally reported in the current assets and current liabilities sections of the consolidated balance sheet, at the end of each reporting period, based on the timing of the satisfaction of the related performance obligation(s). For multi-year software sales with annual invoicing, we perform a significant financing component calculation and recognize the associated interest income throughout the duration of the financing period. In addition, we reclassify the resulting contract asset balances as current and noncurrent receivables as receipt of the consideration is conditional only on the passage of time and there are no performance risk factors present. See the table below for a breakdown of contract assets and contract liabilities.

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | December 31, |  | December 31,
​ |  | 2023 |  | 2022
Contract assets | ​ | $ | 30,176 | ​ | $ | 32,249
Contract liabilities | ​ | $ | 9,521 | ​ | $ | 7,058

​

Revenue recognized for the year ended December 31, 2023 that was included in the contract liability balance at January 1, 2023 was $5.5 million and represented primarily revenue from our fixed-fee, research, and subscription contracts.

Remaining performance obligations

As of December 31, 2023, the Company had $109.1 million of remaining performance obligations, the majority of which are expected to be satisfied within the next year.

NOTE 4—ACQUISITION

Ventana Research Acquisition

On October 31, 2023, a subsidiary of the Company executed an Asset Purchase Agreement with Ventana Research, Inc. (“Ventana Research”) and consummated the acquisition of substantially all assets, and assumed certain liabilities, of Ventana Research. The purchase price was comprised of $1.0 million of cash consideration paid at closing. Ventana Research will also have the right to receive additional consideration paid via earn-out payments, if certain financial targets are met. At the agreement date, the Company estimated such earn-out payment would be $1.7 million.

The following table summarizes the preliminary consideration transferred to acquire Ventana Research, Inc. and the amount of identified assets acquired, and liabilities assumed, as of the agreement date:

​

​ | ​ | ​ | ​
Cash |  | $ | 1,000
Contingent consideration | ​ |  | 1,657
Total allocable purchase price | ​ | $ | 2,657

​

The amount of recognized identifiable assets acquired and liabilities assumed as of the agreement date:

​

​ | ​ | ​ | ​
Accounts receivable | ​ | $ | 404
Intangible assets | ​ |  | 1,400
Contract liabilities | ​ |  | (1,362)
Net assets acquired | ​ | $ | 442
​ | ​ | ​ | ​
Goodwill | ​ | $ | 2,215

​

The primary factors that drove the goodwill recognized, the majority of which is deductible for tax purposes, were the inclusion of the legacy Ventana Research workforce and allowing the Company to penetrate an entirely new market sector: software technology vendors.

Costs associated with this acquisition are included in the selling, general and administrative expense in the Consolidated Statement of Income and Comprehensive Income and totaled $0.1 million during the year ended December 31, 2023. This business combination was accounted for under the acquisition method of accounting, and as such, the aggregate purchase price was allocated on a preliminary basis to the assets acquired and liabilities assumed based on estimated fair values as of the closing date. Based on the valuation and other factors as described above, the purchase price assigned to intangible assets and the amortization period was as follows:

​

​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | ​ | ​
​ |  | Purchase Price |  | Estimated
​ |  | Allocation |  | Useful Lives
Amortizable intangible assets: | ​ | ​ | ​ | ​ | ​

Total intangible assets | ​ | $ | 1,400 | ​ | ​

​

The Consolidated Statement of Income and Comprehensive Income includes revenue from the Ventana Research acquisition subsequent to the closing. Had the acquisition occurred as of January 1, 2023, approximately $3.9 million of revenue would have been recognized.

​

Change 4 Growth Acquisition

​

On October 31, 2022, a subsidiary of the Company executed an Asset Purchase Agreement with Change 4 Growth, LLC (“Change 4 Growth”) and consummated the acquisition of substantially all the assets, and assumed certain liabilities, of Change 4 Growth. The purchase price was comprised of $3.8 million of cash consideration, $0.6 million of shares of ISG common stock issued promptly after closing and Change 4 Growth will also have the right to receive additional consideration paid via earn-out payments, if certain financial targets are met. At the agreement date, the company estimated such earn-out payment would be $5.6 million.

​

The following table summarizes the consideration transferred to acquire Change 4 Growth and the amounts of identified assets acquired, and liabilities assumed as of the agreement date:

​

​ | ​ | ​ | ​
Cash |  | $ | 3,450

NOTE 5—NET INCOME PER COMMON SHARE

Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that would share in the net income of the Company. For the year ended December 31, 2023, 2.3 million restricted stock units have not been considered in the diluted earnings per share calculation, as the effect would anti-dilutive.

The following tables set forth the computation of basic and diluted earnings per share:

NOTE 8—LEASES

​

The Company recognizes lease payments in the consolidated statements of income on a straight-line basis over the lease term. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of the lease payments.

The Company leases its office space and office equipment under long-term operating lease agreements which expire at various dates through November 2030, some of which include options to extend the leases for up to 3 years, and some of which included options to terminate the leases within 1 year. Under the operating leases, the Company pays certain operating expenses relating to the office equipment and leased property.

The components of lease expense were as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Years Ended December 31,

The revolving loan repayment of the outstanding principal amount and interest payment is due on the maturity date of February 22, 2028.

On February 22, 2023, the Company amended and restated its senior secured credit facility to increase the revolving commitments per the revolving facility (the “2023 Credit Agreement”) from $54.0 million to $140.0 million and eliminate its term loan. The material terms under the 2023 Credit Agreement are as follows. Capitalized terms used but not defined herein have the meanings ascribed to them in the 2023 Credit Agreement:

| ● | The revolving credit facility has a maturity date of February 22, 2028.

| ● | The credit facility is secured by all of the equity interests owned by the Company, and its direct and indirect domestic subsidiaries and, subject to agreed exceptions, the Company’s direct and indirect “first-tier” foreign subsidiaries, and a perfected first priority security interest in all of the Company’s and its direct and indirect domestic subsidiaries’ tangible and intangible assets.

| ● | The Company’s direct and indirect existing and future wholly owned domestic subsidiaries serve as guarantors to the Company’s obligations under the senior secured facility.

| ● | At the Company’s option, the credit facility bears interest at a rate per annum equal to either (i) the “Base Rate” (which is the highest of (a) the rate publicly announced from time to time by the administrative agent as its “prime rate,” (b) the Federal Funds Rate plus 0.5% per annum and (c) Term SOFR, plus 1.0%), plus the applicable margin (as defined below) or (ii) Term SOFR (which is the Term SOFR screen rate for the relevant interest period plus a credit spread adjustment of 0.10%) as determined by the administrative agent, plus the applicable margin. The applicable margin is adjusted quarterly based upon the Company’s consolidated leverage ratio. Prior to the end of the first quarter-end following the closing of the credit facility, the applicable margin shall be a percentage per annum equal to 0.50% for the revolving loans maintained as Base Rate loans or 1.50% for the revolving loans maintained as Term SOFR loans.

| ● | The senior secured credit facility contains a number of covenants that, among other things, place restrictions on matters customarily restricted in senior secured credit facilities, including restrictions on indebtedness (including guarantee obligations), liens, fundamental changes, sales or dispositions of property or assets, investments (including loans, advances, guarantees and acquisitions), transactions with affiliates, dividends and other payments in respect of capital stock, optional payments and modifications of other material debt instruments, negative pledges and agreements restricting subsidiary distributions and changes in line of business. In addition, the Company is required to comply with a consolidated leverage ratio and consolidated interest coverage ratio.

| ● | The senior secured credit facility contains customary events of default, including cross-default to other material agreements, judgment default and change of control.

​

The Company’s financial statements include outstanding borrowings of $79.2 million both as of December 31, 2023 and December 31, 2022, which are carried at amortized cost. The fair value of debt is classified within Level 3 of the fair value hierarchy. The fair value of the Company's outstanding borrowings was approximately $79.8 million and $76.5 million at December 31, 2023 and December 31, 2022, respectively. The fair values of debt have been estimated using a discounted cash flow analysis based on the Company's incremental borrowing rate for similar borrowing arrangements. The incremental borrowing rate used to discount future cash flows was 6.9% and 6.3% as of December 31, 2023 and December 31, 2022, respectively. The Company also considered recent transactions of peer group companies for similar instruments with comparable terms and maturities as well as an analysis of current market conditions and interest rates. In the third quarter of 2023, the Company borrowed $5.0 million against the revolver and subsequently repaid $5.0 million during that quarter. The Company is currently in compliance with its financial covenants.

NOTE 13—COMMITMENTS AND CONTINGENCIES

The Company is subject to contingencies which arise through the ordinary course of business. All material liabilities of which management is aware are properly reflected in the financial statements at December 31, 2023 and 2022.

​

Ventana Research Contingent Consideration

As of December 31, 2023, the Company has recorded a liability of $1.7 million representing the estimated fair value of contingent consideration related to the acquisition of Ventana Research, which was classified as “Accrued expenses and other current liabilities” and “Other liabilities” on the consolidated balance sheet.

​

Change 4 Growth Contingent Consideration

​

As of December 31, 2023, the Company has recorded a liability of $4.2 million representing the estimated fair value of contingent consideration related to the acquisition of Change 4 Growth, which was classified as “Accrued expenses and other current liabilities” and “Other liabilities” on the consolidated balance sheet. In April 2023, the Company made a contingent consideration payment of $1.5 million.

NOTE 14—RELATED PARTY TRANSACTIONS

From time to time, the Company may have receivables and payables with employees and shareholders. The Company had outstanding receivables from related parties, including shareholders, totaling $0.2 million and $0.3 million as of December 31, 2023 and 2022, respectively, and no outstanding payables. These transactions related to personal withholding taxes paid on behalf of expatriate employees.

A valuation allowance was established at December 31, 2023 and 2022 due to estimates of future utilization of net operating loss carryovers in the U.S. and certain foreign jurisdictions, derived primarily from acquisitions and recorded through purchase accounting. The valuation allowance at December 31, 2023 and 2022 also includes a full valuation for the Company’s foreign tax credit carryovers and foreign taxes on certain controlled foreign corporations.

As of December 31, 2023, the Company had foreign net operating loss (NOL) carryforwards of approximately $10.2 million. If not utilized, these NOL carryforwards begin to expire in 2024. The Company also has a federal tax credit carryforward of approximately $2.7 million, which will begin to expire in 2026, if not utilized.

Uncertain tax positions

Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more likely than not recognition threshold is measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more likely than not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more likely than not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met. It is the Company’s policy to accrue for interest and penalties related to its uncertain tax positions within income tax expense.

​

We do not expect our unrecognized tax benefits to significantly change in the next twelve months.

The Company has recognized through income tax expense approximately $1.0 million of interest and penalties related to uncertain tax positions. The amount of unrecognized tax benefit, if recognized, that would impact the effective tax rate is $1.8 million. With few exceptions, the Company is no longer subject to U.S. federal, state, local or non-U.S. income tax examinations by tax authorities for years before 2016.

NOTE 16—STOCK-BASED COMPENSATION PLANS

The Amended and Restated 2007 Equity and Incentive Award Plan (“Incentive Plan”) and Amended and Restated 2007 Employee Stock Purchase Plan (“ESPP”) were approved by the Company’s stockholders at our 2014 annual meeting with a subsequent amendment to the Incentive Plan approved by the Company’s stockholders at our 2017 annual meeting as discussed below. Subject to the terms of the Incentive Plan, the Incentive Plan authorizes the grant of awards, which awards may be made in the form of (i) nonqualified stock options; (ii) stock options intended to qualify as incentive stock options under Section 422 of the Internal Revenue Code (stock options described in clause (i) and (ii), “options”); (iii) stock appreciation rights (“SARs”); (iv) restricted stock and/or restricted stock units; (v) other stock based awards; (vi) performance-based awards, which are equity awards or incentive awards intended to qualify for full tax deductibility by the company under Code Section 162 (m); and (vii) incentive awards, a cash-denominated award earnable by achievement of performance goals. The issuance of shares or the payment of cash upon the exercise of an award or in consideration of the cancellation or termination of an award shall reduce the total number of shares available under the Incentive Plan, as applicable. The provisions of each award will vary based on the type of award granted and will be specified by the Compensation Committee of the Board of Directors. Those awards which are based on a specific contractual term will be granted with a term not to exceed ten years. The SARs granted under the Incentive Plan are granted with an exercise price equal to the fair market value of the Common Shares at the time the SARs are granted.

At the 2020 annual meeting, our stockholders approved an amendment to the Incentive Plan to increase the number of shares of common stock available for issuance under the Incentive Plan by 5,500,000 shares (the “Incentive Plan Amendment”). As of December 31, 2023, there were 2,231,197 and 640,318 shares available for grant under the Incentive Plan and ESPP, respectively.

The Company recognized $9.1 million, $7.5 million and $6.5 million in employee stock-based compensation expense during the years ended December 31, 2023, 2022 and 2021, respectively. This expense was recorded in selling, general and administrative in the consolidated statement of comprehensive income.

Restricted Share Awards/Units

The Incentive Plan provides for the granting of restricted share units (“RSU”), the vesting of which is subject to conditions and limitations established at the time of the grant. Recipients of RSU awards will not have the rights of a shareholder of the Company until such date as the shares of common stock are issued or transferred to the recipient. If the employee retires (at the normal retirement age stated in the applicable retirement plan or applicable law, if there is a mandatory retirement age), the restricted shares continue to vest on the same schedule as if the employee remained employed with the Company. Upon a termination of employment due to an employee’s death or permanent disability, the restricted shares become 100% vested. Dividends accrue and will be paid if and when the restricted shares vest.

The Company also granted RSUs to specific employees which have the following characteristics:

● Performance-Based RSU Vesting (Stock Price): Provided the employee continues to be employed through specific date set forth in the award, the RSUs will vest on such date if specific financial performance is met, otherwise the RSUs will be forfeited.

F-25

​

Table of Contents

​

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

​

(tabular amounts in thousands, except per share data)

​

● Time-Based RSU Vesting: So long as the employee continues to be employed through the anniversary of the grant date, the RSUs will become 100% vested on such date.

If an employee’s employment is terminated (i) at any time during the vesting period due to the employee’s death, disability or retirement prior to the applicable vesting date or (ii) so long as the employee continues to be employed through the vesting dates detailed in the award agreement, the RSUs will become vested according to the agreement. However, no shares will be distributed until the applicable pro rata vesting date (and, in the case of the Performance-Based RSUs, only if and to the extent that the performance target is achieved). In all other terminations occurring prior to the applicable vesting date, the RSUs will expire. Pursuant to the terms of the Incentive Plan, in the event of a change in control, the Compensation Committee of the Board of Directors may accelerate vesting of the outstanding awards of RSUs then held by participants. All RSUs will be payable in shares of the Company’s common stock immediately upon vesting. As part of the Incentive Plan Amendment, dividends/dividend equivalents may be paid or credited on other stock-based awards (such as restricted stock units), but those dividends/dividend equivalents must be subject to the same vesting (or more stringent vesting) applicable to the underlying awards.

The fair value of RSUs is determined based on the closing price of the Company’s shares on the grant date. The total fair value is amortized to expense on a straight-line basis over the vesting period.

A summary of the status of the Company’s RSUs issued under its Incentive Plan as of December 31, 2023 and changes during the years then ended, is presented below:

Employee Stock Purchase Plan

The Company uses the Black-Scholes option pricing model to estimate the fair value of shares expected to be issued under the Company’s employee stock purchase plan. The ESPP provides that a total of 3.6 million shares of common stock are reserved for issuance under the plan. The ESPP, which is intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code, is implemented utilizing three-month offerings with purchases occurring at three-month intervals. The ESPP administration is overseen by the Compensation Committee of the Company’s Board of Directors. Employees are eligible to participate if they are employed by the Company for at least 20 hours per week and more than five months in a calendar year. The ESPP permits eligible employees to purchase common stock through payroll deductions, ranging from one to ten percent of their eligible earnings subject to IRS regulated cap of $25,000. The price of common stock purchased under the ESPP is 90% of the fair market value of the common stock on the applicable purchase date. Employees may end their participation in an offering at any time during the offering period, and participation ends
