Overview

Grid Dynamics is a leading provider of technology consulting, platform and product engineering, and advanced analytics services. As a forefront provider of technology consulting, platform and product engineering services, and bespoke software development, we draw from over 7 years of leadership in Enterprise artificial intelligence (“AI”), coupled with profound expertise in cloud, data, and advanced analytics. Our commitment to engineering excellence, R&D leadership, a co-innovation ethos, globally efficient “Follow-the-Sun” delivery model, and an unwavering “whatever it takes” dedication to client success empowers us to solve even the most complex enterprise challenges, ensuring profitable business outcomes and future-proof growth.

Additional market differentiators include:

•

a culture of engineering excellence, R&D investment, and innovation in groundbreaking technologies before they become ubiquitous;

•

a co-innovation model with continuous knowledge-sharing throughout delivery that reduces implementation risk and time-to-value, enables enterprises to build in-house capabilities, retain control of proprietary technology and data, and benefit from the adoption of new technologies; and

•

a global footprint, and a “Follow-the-Sun” delivery model bolstered by engineering talent driven by innovation, and technical mastery, resulting in transformational business outcomes.

Established in 2006 and headquartered in Silicon Valley, Grid Dynamics partners with clients ranging from innovative start-ups to the largest companies in the world. Grid Dynamics believes the key to its success is a culture encouraging an unwavering “whatever it takes” dedication that puts client success over contract terms, products over projects, and real business results over pure technical innovation. With our proprietary processes optimized for innovation, emphasis on talent development, and technical expertise, Grid Dynamics is well-positioned for continued success.

Grid Dynamics has offices across the U.S., Mexico, Jamaica, the U.K., Europe, India, and Argentina. During the last three years, Grid Dynamics acquired JUXT LTD. (“Juxt”), NextSphere Technologies Inc., Mutual Mobile Inc., and Mobile Computing S.A. (“Mobile Computing”). These acquisitions diversified our geographical presence, client base, and industry vertical presence.

Industry Background and Market Opportunity

Digital transformation is a rapidly expanding market that is still in its early stages. Enterprises strive to compete in the digital world, facing the need to transform to survive attacks from the nimbler and more technologically advanced newcomers. Traditional approaches to managing information technology as a mix of vendor solutions and outsourced services often break down in the face of the imperative to innovate through technology. Increasingly, business executives are looking at the use of technology as a competitive advantage rather than a way to cut costs with software-defined capabilities becoming the essence of the business capabilities. The rise of AI signifies a shift from the automation of business processes to the automation of decision-making itself. To differentiate, corporations are directing investments toward building new digital products and experiences, instead of buying off-the-shelf software products and entire business underpinning platforms. This drives demand for highly technical software development, creating an opportunity for pure-play platform engineering and software development service providers such as Grid Dynamics.

TABLE OF CONTENTS

Sophisticated and scalable software platforms developed and continuously adapted to enterprise needs propelled many of today’s most successful companies. Their unique business approaches and ability to move fast in adapting to changing market conditions allowed them to develop strong market positions and maintain defense against competitors. Grid Dynamics is well-placed as a strategic partner of choice for these opportunities. Our focus on the foundation of excellence in platform and software engineering enables the level of collaboration that only a few can offer. Grid Dynamics has offices across Europe, India, and the Americas. As the key drivers of our “Follow-the-Sun” model of engineering excellence, these geographies enable the acceleration of valuable business outcomes for our clients. Our teams and programs are organized and orchestrated for continuous integration, self-sufficiency, and maximum business impact across regions. Another strategic advantage of our “Follow-the-Sun” approach is that these geographies grow technology markets with large talent pools of highly skilled technical talent and cost-efficient scalability due to their large and well-recognized university infrastructures — a valuable asset for fueling our internship programs and attracting top talent. As we expand our geographical reach, we are also investing in developing a multi-discipline approach to address the challenges facing our clients. This involves developing hybrid team capabilities focused on end-to-end problem-solving.

Strategies and Strengths

Grid Dynamics’ objective is to become a global leader in enabling digital transformation at Fortune 1000 companies. Grid Dynamics’ strategy to achieve such an objective is based on leveraging the following core strengths.

Proprietary Processes Optimized for Innovation

Grid Dynamics recognizes the changing dynamics of the IT services space. Increasingly, corporations expect their service providers to participate and help shape innovation programs. This leads to the development of next-level capabilities that traditional service models, used by the traditional outsourcing providers, fail to address effectively. Grid Dynamics melds technical consulting, platform and product engineering, and analytics competencies into unified, cross-functional digital teams that are designed to respond and adapt to changes in a client’s business. The effectiveness of such teams is further increased by close collaboration with a client’s technology and business leadership teams and active inquiry into a client’s business priorities on all levels.

Culture-First Approach to Talent Development

The ever-increasing role of digital transformation leads to the emergence of a new kind of business leader that combines a vision of business transformation with a deep understanding of possibilities brought together by modern digital technology. Earning the trust of these leaders is one of the pillars of Grid Dynamics’ success. Grid Dynamics selects, trains, and promotes its leadership based on the following cultural principles.

•

Global integration. Demands of modern businesses transcend cultural and language boundaries. Grid Dynamics builds teams that are transparently distributed across countries, time zones, and reporting lines.

•

Partnership with client. Grid Dynamics demands accountability and ownership of a client’s success, whether or not such success is a contractual matter. Understanding the goals of Grid Dynamics’ clients and the ability to manage such goals across reporting lines is a must for any leadership role within Grid Dynamics.

•

Technological innovation. Understanding digital transformation and successfully delivering strategic programs is impossible without a strong understanding of emerging technology. Deep knowledge of how new technology, such as cloud, big data, and AI, transforms the way corporations develop their businesses is a prerequisite for leadership roles in Grid Dynamics.

•

Education. Grid Dynamics believes that technology changes rapidly, and Grid Dynamics’ employees must adapt even more rapidly. Grid Dynamics offers many formal and informal training programs, such as Grid University, an online education platform with thousands of hours of training videos, to ensure that professionals can expand and enhance their capabilities.

Our customers benefit from our ability to integrate innovative technologies into their operations, making their supply chains more resilient, agile, and aligned with the digital economy’s demands.

Verticals

Grid Dynamics has strong vertical-specific domain knowledge backed by extensive experience. By merging technology with business processes, Grid Dynamics delivers tailored solutions in several key industry verticals: Tech, Media, and Telecom (“TMT”); Retail; Consumer Packaged Goods (“CPG”)/Manufacturing; Finance.

Tech, Media, and Telecom

Grid Dynamics has a strong presence in the digital technology sector, particularly among analytics, Software as a Service (“SaaS”), and platform vendors that are driven by a constant need for innovation. Grid Dynamics’ long-lasting expertise in complex open-source technology and in building massively scalable distributed systems, the company-wide culture of agile co-creation as well as a deep understanding of digital commerce have enabled Grid Dynamics to build strong business relationships with the leading players in this sector. For example, Grid Dynamics has been providing software engineering, continuous delivery and deployment automation, machine learning, internal tool development, and quality engineering services to one of the largest cloud services providers, becoming one of their key technological services partners.

Retail

By utilizing Grid Dynamics’ deep expertise in the digital retail space and providing a mix of consulting and engineering services, Grid Dynamics enables its clients to win market share, shorten time to market, and reduce the costs of digital operations. For example, Grid Dynamics has worked closely with a large U.S. retail company over many years to develop a strategic omnichannel transformation program and became a key contributor to the development of a new omnichannel platform including consumer experience, product discovery, analytics, and inventory optimization.

CPG and Manufacturing

Grid Dynamics helps its manufacturing customers harness digital transformation by applying novel approaches to engage consumers directly and optimize back-end supply chains. For example, Grid Dynamics accelerated digital transformation in a global shoe manufacturing company by building composable commerce and other digital ecosystem capabilities, replacing a monolithic commerce engine, and speeding time to market with modern and flexible functionality.

Finance

In the early days of Grid Dynamics, the financial sector recognized it for the ability to tackle high-end technology programs, such as moving from the batch to real-time fraud detection. Today, Grid Dynamics has evolved from a niche provider to a proven partner, helping to create agility and lessen time to market in the most challenging regulatory environments.

TABLE OF CONTENTS

Non-GAAP Measures

To supplement our consolidated financial data presented on a basis consistent with generally accepted accounting principles (“GAAP”), this prospectus supplement contains certain non-GAAP financial measures, including Non-GAAP EBITDA, Non-GAAP net income and Non-GAAP diluted earnings per share, or EPS. We have included these non-GAAP financial measures because they are financial measures used by our management to evaluate our core operating performance and trends, to make strategic decisions regarding the allocation of capital and new investments and are among the factors analyzed in making performance-based compensation decisions for key personnel. These measures exclude certain expenses that are required under GAAP. We exclude these items because they are not part of core operations or, in the case of stock-based compensation, non-cash expenses that are determined based in part on our underlying performance.

We believe these supplemental performance measurements are useful in evaluating operating performance, as they are similar to measures reported by our public industry peers and those regularly used by security analysts, investors and other interested parties in analyzing operating performance and prospects. These non-GAAP financial measures are not intended to be a substitute for any GAAP financial measures and, as calculated, may not be comparable to other similarly titled measures of performance of other companies in other industries or within the same industry.

There are significant limitations associated with the use of non-GAAP financial measures. Further, these measures may differ from the non-GAAP information, even where similarly titled, used by other companies and therefore should not be used to compare our performance to that of other companies. We compensate for these limitations by providing investors and other users of our financial information a reconciliation of non-GAAP measures to the related GAAP financial measures. We encourage investors and others to review our financial information in its entirety, not to rely on any single financial measure and to view our non-GAAP measures in conjunction with GAAP financial measures.

We define and calculate our non-GAAP financial measures as follows:

•

Non-GAAP EBITDA: Net income/(loss) before interest income/(expense), provision for income taxes and depreciation and amortization, and further adjusted for the impact of stock-based compensation expense, transaction-related costs (which include, when applicable, professional fees, retention bonuses, and consulting, legal and advisory costs related to Grid Dynamics’ merger and acquisition and capital-raising activities), impairment of goodwill and other income/(expense), net (which includes mainly interest income and expense, foreign exchange gains and losses, fair value adjustments, potential loss contingencies, and other miscellaneous expenses), and restructuring costs.

•

Non-GAAP net income: Net income/(loss) adjusted for the impact of stock-based compensation, impairment of goodwill, transaction-related costs, restructuring costs, other income/expenses, net, and the tax impacts of these adjustments.

•

Non-GAAP diluted EPS: Non-GAAP net income, divided by the diluted weighted-average number of common shares outstanding for the period.

The following tables present the reconciliation of Grid Dynamics’ Non-GAAP EBITDA to its consolidated net income (loss), the most directly comparable GAAP measure, for the periods indicated:

Geographic reorganization includes expenses connected with military actions of Russia against Ukraine and the exit plan announced by the Company and includes travel and relocation-related expenses of employees from the aforementioned countries, severance payments, and allowances as well as legal and professional fees related to geographic repositioning in various locations. These expenses are incremental to those expenses incurred prior to the crisis, clearly separable from normal operations, and not expected to recur once the crisis has subsided and operations return to normal.

TABLE OF CONTENTS

RISK FACTORS

An investment in our securities involves a high degree of risk. You should consider carefully the risks and uncertainties described below, together with all of the other information contained in this prospectus supplement and the other information included and incorporated by reference into this prospectus supplement and the accompanying prospectus, including the risk factors contained in the “Risk Factor” section of our quarterly report on Form 10-Q for the quarterly period ended September 30, 2024, which are hereby specifically incorporated by reference, before deciding to invest in our securities. If any of such risks occur, our business, financial condition and operating results may be materially adversely affected. In that event, the trading price of our securities could decline, and you could lose all or part of your investment. The risks and uncertainties described below or incorporated by reference are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business or results of operations.

Risks Related to This Offering

Our common stock has experienced, and may continue to experience, price volatility, which could result in substantial losses for investors in our common stock.

Our common stock has at times experienced substantial price volatility as a result of many factors, including the general volatility of stock market prices and volumes, changes in securities analysts’ estimates of our financial performance, variations between our actual and anticipated financial results, fluctuations in order or backlog levels, or uncertainty about current global economic conditions. For these reasons, among others, the price of our common stock may continue to fluctuate. In addition, if the stock market in general experiences a loss of investor confidence, the trading price of our common stock could decline for reasons unrelated to our business, financial condition or results of operations. If any of the foregoing occurs, it could cause our stock price to fall and may expose us to lawsuits that, even if unsuccessful, could be costly to defend and be a distraction to management.

Shares eligible for future sale may adversely affect our common stock price.

Sales of our common stock or other securities in the public or private market, or the perception that these sales may occur, could cause the market price of our common stock to decline. This could also impair our ability to raise additional capital through the sale of our equity securities. Under our certificate of incorporation, we are authorized to issue up to 110,000,000 shares of common stock. We cannot predict the size of future issuances of our common stock or other securities or the effect, if any, that future sales and issuances of our common stock and other securities would have on the market price of our common stock.

We have broad discretion in the use of the net proceeds from this offering and may not use them effectively.

Our management has broad discretion in the application of the net proceeds from this offering, including for working capital and other general corporate purposes, including potential acquisitions, and we may spend or invest these proceeds in a way with which our stockholders disagree. Because of the number and variability of factors that will determine our use of the net proceeds from this offering, their ultimate use may vary substantially from their currently intended use.

The failure by our management to apply these funds effectively could harm our business. Pending their use, we may invest such proceeds in a manner that does not produce income or that loses value, which may negatively impact the market price of our common stock.

If you purchase our common stock in this offering, you will incur immediate and substantial dilution.

The public offering price is substantially higher than the net tangible book value per share of our common stock of $3.60 per share as of September 30, 2024. Investors purchasing common stock in this offering will pay a price per share that substantially exceeds the book value of our tangible assets after subtracting our liabilities. As a result, investors purchasing common stock in this offering will incur immediate dilution of $15.10 per share, based on the assumed public offering price of $19.61 per share, the last reported sale price of our common stock on Nasdaq on November 11, 2024.

S-13

TABLE OF CONTENTS

This dilution is due to the substantially lower price paid by our investors who purchased shares prior to this offering as compared to the price offered to the public in this offering, and any previous exercise of stock options granted to our service providers. In addition, as of September 30, 2024, 4,294,147 options to purchase shares of our common stock, and 3,600,016 shares of common stock subject to RSUs and performance share awards were outstanding, as set forth in “The Offering.” The exercise of any of these options, the vesting of RSUs or performance share awards and the exercise of warrants would result in additional dilution. As a result of the dilution to investors purchasing shares in this offering, investors may receive less than the purchase price paid in this offering, if anything, in the event of our liquidation.

FORWARD-LOOKING STATEMENTS

Some of the information contained in this prospectus supplement, the accompanying prospectus, or incorporated herein or therein by reference, contain certain statements that constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Forward-looking statements include all statements that are not historical facts and can be identified by terms such as “anticipates,” “believes,” “could,” “seeks,” “estimates,” “expects,” “intends,” “may,” “plans,” “potential,” “predicts,” “projects,” “should,” “will,” “would,” or similar expressions and the negatives of those terms. Those statements appear in this prospectus supplement and the accompanying prospectus, any accompanying prospectus supplement and the documents incorporated herein and therein by reference, particularly in the sections titled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and include statements regarding the intent, belief or current expectations of our management that are subject to known and unknown risks, uncertainties and assumptions. You are cautioned that any such forward-looking statements are not guarantees of future performance and involve risks and uncertainties, and that actual results may differ materially from those projected in the forward-looking statements as a result of various factors.

Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely upon forward-looking statements as predictions of future events. The events and circumstances reflected in the forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. Except as required by applicable law, including the securities laws of the United States and the rules and regulations of the SEC, we do not plan to publicly update or revise any forward-looking statements contained herein after we distribute this prospectus, whether as a result of any new information, future events or otherwise.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this prospectus, and although we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted a thorough inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

This prospectus and the documents incorporated by reference in this prospectus may contain market data that we obtain from industry sources. These sources do not guarantee the accuracy or completeness of the information. Although we believe that our industry sources are reliable, we do not independently verify the information. The market data may include projections that are based on a number of other projections. While we believe these assumptions to be reasonable and sound as of the date of this prospectus, actual results may differ from the projections.

As a result of a number of known and unknown risks and uncertainties, the Company’s actual results or performance may be materially different from those expressed or implied by these forward-looking statements. The principal factors and uncertainties that make investing in our Company risky include, but are not limited to, the following:

•

we have a relatively short operating history and operate in a rapidly evolving industry, which makes it difficult to evaluate our future prospects and may increase the risk that we will not continue to be successful and may adversely impact our stock price.

•

we may be unable to effectively manage our growth or achieve anticipated growth, particularly as we expand into new geographies and consummate additional acquisitions, which could place significant strain on our management personnel, systems and resources.

•

our revenues have historically been highly dependent on a limited number of clients and industries, and any decrease in demand for outsourced services in these industries may reduce our revenues and adversely affect our business, financial condition and results of operations.

•

we have incurred significant net losses in recent years, we expect to incur losses in the future and we may not be able to generate sufficient revenue to achieve and maintain profitability.

TABLE OF CONTENTS

•

the impact of the military action in Ukraine has affected and may continue to affect our business.

•

macroeconomic conditions, inflationary pressures, and the geopolitical climate could adversely affect our operating results and growth prospects.

•

our revenues are highly dependent on clients primarily located in the U.S. Any economic downturn in the U.S. or in other parts of the world, including Europe, or disruptions in the credit markets may have a material adverse effect on our business, financial condition and results of operations.

•

we face intense competition.

•

damage to our reputation may adversely impact our ability to generate and retain business.

•

our failure to successfully attract, hire, develop, motivate and retain highly skilled personnel could have a significant adverse effect on our business, financial condition, and results of operations.

•

our business operations may be severely disrupted if we lose the services of our senior executives and key employees.

•

failure to adapt to changing technologies, methodologies, and evolving industry standards may have a material adverse effect on our business, financial condition, and results of operations.

•

social and ethical issues relating to the use of artificial intelligence (“AI”) in our offerings may result in reputational harm or liability.

•

security breaches and incidents, system failures or errors, and other disruptions to our networks and systems, could result in unauthorized access to, or disclosure or other processing of, confidential information and expose us to liability, which would cause our business and reputation to suffer.

•

undetected software design defects, errors or failures may result in loss of business or in liabilities that could have a material adverse effect on our reputation, business and results of operations.

•

war, terrorism, other acts of violence, or natural or man-made disasters may affect the markets in which we operate, our clients and our service delivery.

•

our global business, especially in CIS and CEE countries, exposes us to significant legal, economic, tax and political risks.

•

acquisitions (including our recent acquisitions of Juxt and Mobile Computing) could be difficult to identify and integrate, divert the attention of management, disrupt our business, dilute stockholder value and adversely affect our financial condition and results of operations, we may not achieve the financial and strategic goals that were contemplated at the time of a transaction, and we may be exposed to claims, liabilities and disputes as a result of the transaction that may adversely impact our business, operating results and financial condition; and

•

other risks and uncertainties included or incorporated by reference in this prospectus supplement and the accompanying prospectus, including those set forth in “Risk Factors.”

Should one or more of these risks or uncertainties materialize, or should any of the underlying assumptions prove incorrect, actual results may vary in material respects from those expressed or implied by these forward-looking statements. You should not place undue reliance on these forward-looking statements.

TABLE OF CONTENTS

USE OF PROCEEDS

We estimate that the net proceeds to us from our sale of the shares of common stock in this offering will be approximately $92.8 million, or approximately $106.8 million, if the underwriters’ option to purchase additional shares from us is exercised in full, based upon an assumed public offering price of $19.61 per share, the last reported sale price of our common stock on Nasdaq on November 11, 2024, and after deducting estimated underwriting discounts and commissions and estimated offering expenses.

Each $1.00 increase (decrease) in the assumed public offering price of $19.61 per share would increase (decrease) the net proceeds to us from this offering by approximately $4.8 million, assuming the number of shares offered by us, as set forth on the cover page of this prospectus supplement, remains the same and after deducting estimated underwriting discounts and commissions and estimated offering expenses. We may also increase or decrease the number of shares we are offering. Each increase (decrease) of 1.0 million shares in the number of shares offered by us would increase (decrease) the net proceeds to us from this offering by approximately $18.7 million, assuming that the assumed public offering price remains the same, and after deducting the estimated underwriting discounts and commissions and estimated offering expenses. We do not expect that a change in the public offering price or the number of shares by these amounts would have a material effect on our uses of the proceeds from this offering.

The principal purposes of this offering are to increase our financial flexibility, obtain additional capital and to increase our public float. We intend to use the net proceeds from this offering for working capital, capital expenditures and other general corporate expenses. We may also use a portion of our net proceeds to fund potential acquisitions of, or investments in, complementary technologies or businesses, although we have no present commitments or agreements to enter into any such acquisitions or to make any such investments. The timing and amount of our actual expenditures will be based on many factors, including cash flows from operations and the anticipated growth of our business.

The expected use of net proceeds of this offering represents our current intentions based upon our present plans and business conditions. We cannot specify with certainty all of the particular uses for the net proceeds to be received upon the closing of this offering. Pending such uses, we plan to invest the net proceeds of this offering in short-term, investment grade, interest-bearing deposits or securities, such as direct or guaranteed obligations of the U.S. government.

TABLE OF CONTENTS

DIVIDEND POLICY

We have not paid any cash dividends on our common stock since our merger with ChaSerg. The payment of cash dividends in the future will be dependent upon revenues and earnings, if any, capital requirements and general financial condition from time to time and may be limited by the terms of any financing and/or other agreements entered into by us or our subsidiaries from time to time and by requirements under the laws of our subsidiaries’ respective jurisdictions of incorporation to set aside a portion of their net income in each year to legal reserves.

The payment of any cash dividends will be within the discretion of our board of directors and the board of directors will consider whether or not to institute a dividend policy. It is presently expected that we will retain all earnings for use in our business operations and, accordingly, it is not expected that our board of directors will declare any dividends in the foreseeable future. Our ability to pay cash dividends on our common stock may also be limited by the terms of the credit agreement we entered into on March 15, 2022 by and among us, as borrower, the guarantors party thereto from time to time, the lenders party thereto from time to time, and JPMorgan Chase Bank, N.A., as administrative agent for the lenders (our “2022 Credit Agreement”) and the terms of any future debt or indebtedness.

CAPITALIZATION

The following table summarizes our unaudited capitalization as of September 30, 2024:

•

on an actual basis; and

•

on an as adjusted basis to reflect receipt of approximately $92.8 million in net proceeds from the sale and issuance by us of shares of common stock in this offering at an assumed public offering price of $19.61 per share, the last reported sale price of our common stock on Nasdaq on November 11, 2024 after deducting estimated underwriting discounts and commissions and estimated offering expenses.

You should read the information in this table together with our consolidated financial statements and related notes to those statements, as well as the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” incorporated by reference in this prospectus supplement and the accompanying prospectus.

Each $1.00 increase (decrease) in the assumed public offering price of $19.61 per share, the last reported sale price of our common stock on Nasdaq on November 11, 2024, would increase (decrease) each of cash and equivalents, total stockholders’ equity and total debt and stockholders’ equity by approximately $4.8 million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus supplement, remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses. We may also increase or decrease the number of shares we are offering. An increase (decrease) of 1.0 million shares in the number of shares offered by us would increase (decrease) each of cash and cash equivalents, total stockholders’ equity and total debt and stockholders’ equity by approximately $18.7 million, assuming that the assumed public offering price remains the same, and after deducting the estimated underwriting discounts and commissions and estimated offering expenses. The as adjusted information discussed above is illustrative only and will change based on the actual public offering price and other terms of this offering determined at pricing.

The number of shares of common stock outstanding is based on 76,742,933 shares of common stock outstanding as of September 30, 2024, which excludes the following:

•

1,707,230 shares of our common stock issuable upon the vesting of RSUs outstanding as of September 30, 2024;

•

120,675 shares of our common stock issuable upon the vesting of RSUs granted after September 30, 2024;

•

1,892,786 shares of our common stock issuable upon the vesting of performance stock awards outstanding as of September 30, 2024; and

•

2,925,662 shares of our common stock reserved for future issuance under the 2020 Plan, and any additional shares that become available under the 2020 Plan pursuant to the provisions thereof.

TABLE OF CONTENTS

DILUTION

If you invest in our common stock, you will experience immediate and substantial dilution in the net tangible book value of your shares of common stock. Dilution in net tangible book value represents the difference between the price to public per share of our common stock and the as adjusted net tangible book value per share, as adjusted to give effect to this offering.

Net tangible book value represents our total tangible assets less total liabilities and deferred offering costs, divided by the number of shares of common stock outstanding as of September 30, 2024. Our net tangible book value as of September 30, 2024 was $276.3 million or $3.60 per share. After giving further effect to the sale and issuance of 5,000,000 shares of common stock in this offering at an assumed public offering price of $19.61 per share, the last reported sale price of our common stock on Nasdaq on November 11, 2024, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, our as adjusted net tangible book value as of September 30, 2024 would have been approximately $369.1 million, or $4.51 per share. This represents an immediate increase in net tangible book value of $0.91 per share to existing stockholders and an immediate dilution of $15.10 per share to new investors purchasing common stock in this offering.

The following table illustrates this dilution on a per share basis to new investors:

Assumed public offering price per share			$	19.61
Net tangible book value per share as of September 30, 2024	$	3.60
Increase in net tangible book value per share attributable to investors participating in the offering	$	0.91
As adjusted net tangible book value per share, as adjusted to give effect to this offering			$	4.51
Dilution in as adjusted net tangible book value per share to investors participating in this offering			$	15.10

Each $1.00 increase (decrease) in the assumed public offering price of $19.61 per share would increase (decrease) our as adjusted net tangible book value by approximately $4.8 million, or approximately $0.06 per share, and increase (decrease) the dilution per share to investors participating in this offering by approximately $0.94 per share, assuming that the aggregate amount of shares offered by us, as set forth on the cover page of this prospectus supplement, remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses. We may also increase or decrease the number of shares we are offering. An increase of 1.0 million shares in the number of shares offered by us would increase our as adjusted net tangible book value by approximately $18.7 million, or $0.23 per share, and the dilution per share to investors participating in this offering would decrease by $0.17 per share, assuming that the assumed public offering price remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses. Similarly, a decrease of 1.0 million shares in the number of shares offered by us would decrease our as adjusted net tangible book value by approximately $18.7 million, or $0.23 per share, and the dilution per share to investors participating in this offering would increase by $0.18 per share, assuming that the assumed public offering price remains the same, and after deducting underwriting estimated discounts and commissions and estimated offering expenses. The as adjusted information discussed above is illustrative only and will change based on the actual public offering price and other terms of this offering determined at pricing.

If the underwriters exercise in full their option to purchase additional shares of common stock from us in this offering, the as adjusted net tangible book value per share after the offering would be $4.64 per share, the increase in the net tangible book value per share to existing stockholders would be $1.04 per share, and the dilution to new investors purchasing common stock in this offering would be $14.97 per share.

The number of shares of common stock outstanding is based on 76,742,933 shares of common stock outstanding as of September 30, 2024, which excludes the following:

TABLE OF CONTENTS

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES FOR
NON-U.S. HOLDERS OF COMMON STOCK

The following is a summary of the material U.S. federal income tax considerations of the ownership and disposition of our common stock acquired in this offering by a “non-U.S. holder” (as defined below) but does not purport to be a complete analysis of all the potential tax considerations relating thereto. This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended (“Code”), Treasury Regulations promulgated thereunder, administrative rulings and judicial decisions, all as of the date hereof. These authorities may be changed, possibly retroactively, so as to result in U.S. federal income tax consequences different from those set forth below. We have not sought, and do not intend to seek, any ruling from the Internal Revenue Service (“IRS”) with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS or a court will agree with such statements and conclusions.

This summary also does not address the tax considerations arising under the laws of any non-U.S., state or local jurisdiction, under U.S. federal gift and estate tax rules or under any applicable tax treaty. In addition, this discussion does not address any potential application of the Medicare contribution tax on net investment income or any tax considerations applicable to an investor’s particular circumstances or to investors that may be subject to special tax rules, including, without limitation:

•

banks, insurance companies, regulated investment companies, real estate investment trusts or other financial institutions;

•

tax-exempt organizations or accounts;

•

pension plans and tax-qualified retirement plans;

•

controlled foreign corporations, passive foreign investment companies and corporations that accumulate earnings to avoid U.S. federal income tax;

•

brokers or dealers in securities or currencies;

•

traders in securities that elect to use a mark-to-market method of accounting for their securities holdings;

•

persons that own, or are deemed to own, more than 5% of our capital stock (except to the extent specifically set forth below);

•

U.S. expatriates and certain other former citizens or long-term residents of the United States;

•

partnerships (or entities or arrangements classified as such for U.S. federal income tax purposes), other pass-through entities, and investors therein;

•

persons subject to the alternative minimum tax;

•

persons who hold our common stock as a position in a hedging transaction, “straddle,” “conversion transaction” or other risk reduction transaction;

•

persons who hold or receive our common stock pursuant to the exercise of any employee stock option or otherwise as compensation;

•

persons subject to special tax accounting rules as a result of any item of gross income with respect to our common stock being taken into account in an “applicable financial statement” as defined in Section 451(b) of the Code;

•

persons who do not hold our common stock as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment); or

•

persons deemed to sell our common stock under the constructive sale provisions of the Code.

In addition, if a partnership, entity or arrangement classified as a partnership or flow-through entity for U.S. federal income tax purposes holds our common stock, the tax treatment of a partner or beneficial owner generally will depend on the status of the partner or beneficial owner, the activities of the partnership or other entity, and certain determinations made at the partner or beneficial owner level. A partner or beneficial owner

S-22

TABLE OF CONTENTS

in a partnership or other such entity that will hold our common stock should consult his, her or its own tax advisor regarding the tax consequences of the purchase, ownership and disposition of our common stock through a partnership or other such entity, as applicable.

You are urged to consult your tax advisor with respect to the application of the U.S. federal income tax laws to your particular situation, as well as any tax consequences of the purchase, ownership and disposition of our common stock arising under the U.S. federal gift or estate tax rules or under the laws of any state, local, non-U.S. or other taxing jurisdiction or under any applicable tax treaty.

Non-U.S. Holder Defined

For purposes of this discussion, you are a “non-U.S. holder” if you are a beneficial owner of our common stock that, for U.S. federal income tax purposes, is not a partnership (including any entity or arrangement treated as a partnership and the equity holders therein) or:

•

an individual who is a citizen or resident of the United States;

•

a corporation (or other entity treated as a corporation for U.S. federal income tax purposes), created in or organized under (or treated as created in or organized under) the law of the United States or any political subdivision thereof;

•

an estate whose income is subject to U.S. federal income tax regardless of its source; or

•

a trust (1) whose administration is subject to the primary supervision of a U.S. court and that has one or more U.S. persons (within the meaning of the Code) who have the authority to control all substantial decisions of the trust or (2) that has made a valid election under applicable Treasury Regulations to be treated as a U.S. person.

Distributions

As described in “Dividend Policy,” we have never declared or paid any cash dividends on our capital stock since our merger with ChaSerg, and we do not expect to pay any dividends in the foreseeable future. However, if we do make distributions on our common stock, those payments will generally constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed both our current and our accumulated earnings and profits, the excess will constitute a return of capital and will first reduce your basis in our common stock (determined separately with respect to each share of our common stock), but not below zero, and then will be treated as gain from the sale of stock as described below in “— Gain on Disposition of Common Stock.”

Subject to the discussions below on effectively connected income and in “— Backup Withholding and Information Reporting” and “— Foreign Account Tax Compliance Act (FATCA),” any dividend paid to you generally will be subject to U.S. federal withholding tax either at a rate of 30% of the gross amount of the dividend or such lower rate as may be specified by an applicable income tax treaty between the United States and your country of residence. In order to receive a reduced treaty rate, you must provide us with a properly executed IRS Form W-8BEN or W-8BEN-E or other appropriate version of IRS Form W-8 certifying qualification for the reduced rate. Under applicable Treasury Regulations, we may withhold up to 30% of the gross amount of the entire distribution even if the amount constituting a dividend, as described above, is less than the gross amount. If you are eligible for a reduced rate of U.S. federal withholding tax pursuant to an income tax treaty and do not timely provide us with such documentation, you may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. If you hold our common stock through a financial institution or other agent acting on your behalf, you will be required to provide appropriate documentation to the agent, which then will be required to provide certification to us or our paying agent, either directly or through other intermediaries.

Dividends received by you that are treated as effectively connected with your conduct of a U.S. trade or business (and, if required by an applicable income tax treaty, are attributable to a permanent establishment or fixed base maintained by you in the United States) are generally exempt from the 30% U.S. federal withholding tax, subject to the discussion below in “— Backup Withholding and Information Reporting” and “— Foreign Account Tax Compliance Act (FATCA).” In order to obtain this exemption, you must provide us with a

S-23

TABLE OF CONTENTS

properly executed IRS Form W-8ECI or other appropriate form properly certifying such exemption. Such effectively connected dividends, although not subject to U.S. federal withholding tax, are taxed at the same graduated rates applicable to U.S. persons, net of certain deductions and credits, subject to an applicable income tax treaty providing otherwise. In addition, if you are a corporate non-U.S. holder, dividends you receive that are effectively connected with your conduct of a U.S. trade or business (and, if an income tax treaty applies, are attributable to a permanent establishment or fixed base maintained by you in the United States) may also be subject to a branch profits tax at a rate of 30% or such lower rate as may be specified by an applicable income tax treaty between the United States and your country of residence. You should consult your tax advisor regarding the tax consequences of the ownership and disposition of our common stock, including any applicable tax treaties that may provide for different rules.

Gain on Disposition of Common Stock

Subject to the discussion in “— Backup Withholding and Information Reporting,” you generally will not be required to pay U.S. federal income tax on any gain realized upon the sale or other taxable disposition of our common stock unless:

•

the gain is effectively connected with your conduct of a U.S. trade or business (and, if an applicable income tax treaty so provides, the gain is attributable to a permanent establishment or fixed base maintained by you in the United States);

•

you are an individual who is present in the United States for a period or periods aggregating 183 days or more during the calendar year in which the sale or disposition occurs and certain other conditions are met; or

•

our common stock constitutes a United States real property interest by reason of our status as a “United States real property holding corporation” (“USRPHC”) for U.S. federal income tax purposes at any time within the shorter of the five-year period preceding your disposition of, or your holding period for, our common stock, unless our common stock is regularly traded on an established securities market and you hold no more than 5% of our outstanding common stock, directly, indirectly and constructively, at all times, during the shorter of the five-year period ending on the date of the taxable disposition or your holding period for our common stock.

We believe that we are not currently and will not become a USRPHC for U.S. federal income tax purposes, and the remainder of this discussion so assumes. However, because the determination of whether we are a USRPHC depends on the fair market value of our U.S. real property relative to the fair market value of our U.S. and worldwide real property plus our other business assets, there can be no assurance that we will not become a USRPHC in the future. If we are a USRPHC and either our common stock is not regularly traded on an established securities market or you hold, or are treated as holding, more than 5% of our outstanding common stock, directly or indirectly, during the applicable testing period, you will generally be taxed on any gain in the same manner as gain that is effectively connected with the conduct of a U.S. trade or business, except that the branch profits tax generally will not apply. If we are a USRPHC and our common stock is not regularly traded on an established securities market, your proceeds received on the disposition of shares will also generally be subject to withholding at a rate of 15%. You are encouraged to consult your own tax advisors regarding the possible consequences to you if we are, or were to become, a USRPHC.

If you are a non-U.S. holder described in the first bullet above, you will be required to pay tax on the gain derived from the sale (net of certain deductions and credits) under regular graduated U.S. federal income tax rates, and a corporate non-U.S. holder described in the first bullet above also may be subject to the branch profits tax at a 30% rate, or such lower rate as may be specified by an applicable income tax treaty. If you are an individual non-U.S. holder described in the second bullet above, you will be subject to tax on such gain at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on the gain derived from the sale, which gain may be offset by U.S. source capital losses for the year, provided you have timely filed U.S. federal income tax returns with respect to such losses. You should consult your tax advisor regarding any applicable income tax or other treaties that may provide for different rules.

TABLE OF CONTENTS

Backup Withholding and Information Reporting

Generally, we must report annually to the IRS the amount of dividends paid to you, your name and address and the amount of tax withheld, if any. A similar report will be sent to you. Pursuant to applicable income tax treaties or other agreements, the IRS may make these reports available to tax authorities in your country of residence.

Payments of dividends on or of proceeds from the disposition of our common stock made to you may also be subject to backup withholding at a current rate of 24% and information reporting unless you establish an exemption, for example, by properly certifying your non-U.S. status on a properly completed IRS Form W-8BEN or W-8BEN-E or another appropriate version of IRS Form W-8. Notwithstanding the foregoing, backup withholding may apply if either we or our paying agent has actual knowledge, or reason to know, that you are a U.S. person. In addition, proceeds of the sale or other taxable disposition of our common stock within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting if the applicable withholding agent receives the certification described above and does not have actual knowledge or reason to know that you are a U.S. person or you otherwise establish an exemption. Proceeds of a disposition of our common stock conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.

Backup withholding is not an additional tax; rather, the U.S. federal income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund or credit may generally be obtained from the IRS, provided that the required information is furnished to the IRS in a timely manner.

Foreign Account Tax Compliance Act (FATCA)

The Foreign Account Tax Compliance Act, Treasury Regulations issued thereunder and official IRS guidance, collectively “FATCA,” generally impose a U.S. federal withholding tax of 30% on dividends on, and, subject to the discussion of certain proposed Treasury Regulations below, the gross proceeds from a sale or other disposition of our common stock, paid to a “foreign financial institution” (as specially defined under these rules), unless such institution enters into an agreement with the U.S. government to, among other things, withhold on certain payments and to collect and provide to the U.S. tax authorities substantial information regarding the U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners) or otherwise establishes an exemption. FATCA also generally imposes a U.S. federal withholding tax of 30% on dividends on and, subject to the discussion of certain proposed Treasury Regulations below, the gross proceeds from a sale or other disposition of our common stock paid to a “non-financial foreign entity” (as specially defined under these rules) unless such entity provides the withholding agent with a certification identifying the substantial direct and indirect U.S. owners of the entity, certifies that it does not have any substantial U.S. owners or otherwise establishes an exemption. The withholding tax will apply regardless of whether the payment otherwise would be exempt from U.S. nonresident and backup withholding tax, including under the other exemptions described above. Under certain circumstances, a non-U.S. holder might be eligible for refunds or credits of such taxes. An intergovernmental agreement between the United States and an applicable foreign country may modify the requirements described in this section. Prospective investors should consult with their own tax advisors regarding the application of FATCA withholding to their investment in, and ownership and disposition of, our common stock.

The Treasury Secretary has issued proposed Treasury Regulations that, if finalized in their present form, would eliminate withholding under FATCA with respect to payments of gross proceeds from a sale or other disposition of our common stock. In the preamble to such proposed Treasury Regulations, the U.S. Treasury stated that taxpayers may generally rely on the proposed Treasury Regulations until final regulations are issued.

The preceding discussion of U.S. federal tax considerations is for general information only. It is not tax advice to investors in their particular circumstances. Each prospective investor should consult its own tax advisor regarding the particular U.S. federal, state and local and non-U.S. tax consequences of purchasing, holding and disposing of our common stock, including the consequences of any proposed change in applicable laws.

UNDERWRITING

We are offering the shares of common stock described in this prospectus supplement through a number of underwriters. J.P. Morgan Securities LLC and William Blair & Company, L.L.C. are acting as joint book-running managers of the offering and as representatives of the underwriters. We intend to enter into an underwriting agreement with the underwriters. Subject to the terms and conditions of the underwriting agreement, we will agree to sell to the underwriters, and each underwriter will severally agree to purchase, at the public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus supplement, the number of shares of common stock listed next to its name in the following table:

Underwriter			Number of Shares
J.P. Morgan Securities LLC
William Blair & Company, L.L.C.
TD Securities (USA) LLC
Needham & Company, LLC
Total

The underwriters will be committed to purchase all the shares of common stock offered by us if they purchase any shares. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated.

The underwriters propose to offer the shares of common stock directly to the public at the public offering price set forth on the cover page of this prospectus supplement and to certain dealers at that price less a concession not in excess of $ per share. After the offering of the shares to the public, if all of the shares of common stock are not sold at the public offering price, the underwriters may change the offering price and the other selling terms. Sales of any shares made outside of the United States may be made by affiliates of the underwriters. In addition, the underwriters may offer and sell shares through certain of their affiliates.

The underwriters have an option to buy up to an additional 750,000 shares of common stock from us. The underwriters have 30 days from the date of this prospectus supplement to exercise this option to purchase additional shares. If any shares are purchased with this option to purchase additional shares, the underwriters will purchase shares in approximately the same proportion as shown in the table above. If any additional shares of common stock are purchased, the underwriters will offer the additional shares on the same terms as those on which the shares are being offered.

The underwriting fee is equal to the public offering price per share of common stock less the amount paid by the underwriters to us per share of common stock. The underwriting fee is $ per share. The following table shows the per share and total underwriting discounts and commissions to be paid to the underwriters assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares.

We estimate that the total expenses of this offering, including registration, filing and listing fees, printing fees and legal and accounting expenses, but excluding the underwriting discounts and commissions, will be approximately $600,000. The underwriters have agreed to reimburse us for certain expenses.

A copy of this prospectus supplement and the accompanying prospectus in electronic format may be made available on the websites maintained by one or more underwriters, or selling group members, if any, participating in the offering. The underwriters may agree to allocate a number of shares to underwriters and selling group members for sale to their online brokerage account holders.

TABLE OF CONTENTS

In connection with this offering, the underwriters may engage in stabilizing transactions, which involves making bids for, purchasing and selling shares of common stock in the open market for the purpose of preventing or retarding a decline in the market price of the common stock while this offering is in progress. These stabilizing transactions may include making short sales of common stock, which involves the sale by the underwriters of a greater number of shares of common stock than they are required to purchase in this offering, and purchasing shares of common stock on the open market to cover positions created by short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ option to purchase additional shares referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriters may close out any covered short position either by exercising their option to purchase additional shares, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriters will consider, among other things, the price of shares available for purchase in the open market compared to the price at which the underwriters may purchase shares through the option to purchase additional shares. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriters create a naked short position, they will purchase shares in the open market to cover the position.

The underwriters have advised us that, pursuant to Regulation M of the Securities Act, they may also engage in other activities that stabilize, maintain or otherwise affect the price of the common stock, including the imposition of penalty bids. This means that if the representatives of the underwriters purchase common stock in the open market in stabilizing transactions or to cover short sales, the representatives can require the underwriters that sold those shares as part of this offering to repay the underwriting discount received by them.

These activities may have the effect of raising or maintaining the market price of the common stock or preventing or retarding a decline in the market price of the common stock, and, as a result, the price of the common stock may be higher than the price that otherwise might exist in the open market. If the underwriters commence these activities, they may discontinue them at any time. The underwriters may carry out these transactions on Nasdaq, in the over-the-counter market or otherwise.

Other relationships

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. Certain of the underwriters and their affiliates have provided, and may provide from time to time in the future, a variety of these services to the Company and to persons and entities with relationships with the Company, for which they received and may receive customary fees and expenses. In particular, JPMorgan Chase Bank, N.A., an affiliate of J.P. Morgan Securities LLC, is the administrative agent under our 2022 Credit Agreement. In addition, affiliates of certain underwriters are lenders under our 2022 Credit Agreement. As of September 30, 2024, the Company did not have any outstanding debt under the 2022 Credit Agreement. In connection with their participation in our 2022 Credit Agreement, such affiliates receive customary fees, and to the extent we use any of the net proceeds from this offering to repay borrowings outstanding under our 2022 Credit Agreement, such parties will receive their proportionate share of any amount of our 2022 Credit Agreement that is repaid with the net proceeds of this offering.

In addition, in the ordinary course of their various business activities, the underwriters and their respective affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively traded securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of their customers, and such investment and trading activities may involve or relate to assets, securities and/or instruments of the Company (directly, as collateral securing other obligations or otherwise) and/or persons and entities with relationships with the Company. The underwriters and their respective affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such assets, securities or instruments and may at any time hold, or recommend to clients that they should acquire, long and/or short positions in such assets, securities and instruments.

ENFORCEABILITY OF CIVIL LIABILITIES

Certain of our directors named in this prospectus reside outside of the United States. A significant portion of the assets of certain of our directors are located outside of the United States. As a result, you may have difficulty serving legal process within the United States upon any of these persons. You may also have difficulty enforcing, both in and outside the United States, judgments you may obtain in U.S. courts against those persons in any action, including actions based upon the civil liability provisions of U.S. federal or state securities laws.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

LEGAL MATTERS

The validity of the shares of common stock offered hereby will be passed upon for us by Willkie Farr & Gallagher LLP, New York, New York. Certain legal matters in connection with this offering will be passed upon for the underwriters by DLA Piper LLP (US), New York, New York.

EXPERTS

TABLE OF CONTENTS

RISK FACTORS

An investment in our securities involves a high degree of risk. The prospectus supplement applicable to each offering of our securities will contain a discussion of the risks applicable to an investment in our securities. Prior to making a decision about investing in our securities, you should carefully consider the specific risk factors discussed in the section of the applicable prospectus supplement titled “Risk Factors,” together with all of the other information contained or incorporated by reference in the prospectus supplement or appearing or incorporated by reference in this prospectus. You should also consider the risks, uncertainties and assumptions discussed under “Part I — Item 1A — Risk Factors” of our most recent Annual Report on Form 10-K and in “Part II — Item 1A — Risk Factors” in our most recent Quarterly Report on Form 10-Q filed subsequent to such Form 10-K that are incorporated herein by reference, as may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future. The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations.

TABLE OF CONTENTS

FORWARD-LOOKING STATEMENTS

This prospectus, each prospectus supplement and the information incorporated by reference in this prospectus and each prospectus supplement contain certain statements that constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act, and Section 21E of the Exchange Act. Forward-looking statements include all statements that are not historical facts and can be identified by terms such as “anticipates,” “believes,” “could,” “seeks,” “estimates,” “expects,” “intends,” “may,” “plans,” “potential,” “predicts,” “projects,” “should,” “will,” “would,” or similar expressions and the negatives of those terms. Those statements appear in this prospectus, any accompanying prospectus supplement and the documents incorporated herein and therein by reference, particularly in the sections titled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and include statements regarding the intent, belief or current expectations of our management that are subject to known and unknown risks, uncertainties and assumptions. You are cautioned that any such forward-looking statements are not guarantees of future performance and involve risks and uncertainties, and that actual results may differ materially from those projected in the forward-looking statements as a result of various factors.

TABLE OF CONTENTS

USE OF PROCEEDS

Unless we specify otherwise in the applicable prospectus supplement accompanying this prospectus, we will use the net proceeds from the sale of the securities for general corporate purposes.

TABLE OF CONTENTS

DESCRIPTION OF COMMON STOCK

This section describes the general terms and provisions of our common stock. For more detailed information, you should refer to our second amended and restated certificate of incorporation (our “certificate of incorporation”), our amended and restated bylaws (our “bylaws”) and the description of our common stock, each incorporated by reference into the registration statement of which this prospectus forms a part, and filed as exhibits to our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed with the SEC on February 29, 2024.

Common Stock

We are authorized to issue up to 110,000,000 shares of common stock, $0.0001 par value per share.

Voting Rights

Each holder of our common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors. Our stockholders do not have cumulative voting rights in the election of directors. Accordingly, holders of a plurality of the votes cast by the stockholders present in person or represented by proxy at the meeting are able to elect all of the directors.

Dividend Rights

Holders of common stock will be entitled to receive such dividends, if any, as may be declared from time to time by our board of directors in its discretion out of funds legally available therefor. In no event will any stock dividends or stock splits or combinations of stock be declared or made on common stock unless the shares of common stock at the time outstanding are treated equally and identically.

Liquidation, Dissolution and Winding Up

In the event of our voluntary or involuntary liquidation, dissolution, distribution of assets or winding-up, the holders of our common stock will be entitled to receive an equal amount per share of all of our assets of whatever kind available for distribution to stockholders, after the rights of the holders of our preferred stock have been satisfied, as may be established by our board of directors.

Preemptive or Other Rights

Our stockholders will have no preemptive or other subscription rights and there are no sinking fund or redemption provisions applicable to our common stock.

Election of Directors

Our certificate of incorporation provides for our board of directors to be divided into three classes, Class I, Class II and Class III, with only one class of directors being elected in each year and each class (except for those directors appointed prior to our first annual meeting of stockholders) serving a three-year term. There is no cumulative voting with respect to the election of directors, with the result that the election of all directors is determined by a plurality of the votes cast by the stockholders present in person or represented by proxy at the meeting and entitled to vote thereon.

Certain Anti-Takeover Provisions of Delaware Law, our Certificate of Incorporation, and our Bylaws

Our certificate of incorporation provides that our board of directors is classified into three classes of directors. As a result, in most circumstances, a person will be able to gain control of our board only by successfully engaging in a proxy contest at three or more annual meetings.

Our certificate of incorporation does not provide for any action required or permitted to be taken by stockholders to be effected by written consent. Our certificate of incorporation provides that directors may be removed prior to the expiration of their terms by stockholders only for cause and upon the affirmative vote of at least a majority of the voting power of all outstanding common stock.

TABLE OF CONTENTS

Our certificate of incorporation requires that changes or amendments to the certificate of incorporation or the bylaws must be approved by at least a majority of the voting power of the then-outstanding common stock.

Our certificate of incorporation does not provide for cumulative voting in the election of directors. Instead, our board of directors is empowered to elect a director to fill a vacancy created by the expansion of the board of directors or the resignation, death, or removal of a director in certain circumstances. Our advance notice procedures include requirements that the stockholders must comply with in order to nominate candidates to our board of directors or to propose matters to be acted upon at a stockholders’ meeting.

Our certificate of incorporation provides that special meetings of stockholders may be called only by the chairman of our board of directors, our chief executive officer or a majority of our board of directors, and stockholders are specifically denied the right to call special meetings.

Our certificate of incorporation provides that stockholders seeking to bring business before any meeting of stockholders or to nominate candidates for election as directors at any meeting of stockholders must provide advance notice as provided in our bylaws. These advance notice procedures may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed and may also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempt to obtain control of the Company.

Our authorized but unissued common stock and preferred stock are available for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred stock could render more difficult or discourage an attempt to obtain control of the Company by means of a proxy contest, tender offer, merger or otherwise.

Exclusive Forum

Our bylaws provide that the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, another State court in Delaware or the federal district court for the District of Delaware) shall, to the fullest extent permitted by law, be the sole and exclusive forum for the following (except for any claim as to which such court determines that there is an indispensable party not subject to the jurisdiction of such court (and the indispensable party does not consent to the personal jurisdiction of such court within 10 days following such determination), which is vested in the exclusive jurisdiction of a court or forum other than such court or for which such court does not have subject matter jurisdiction):

•

any derivative action or proceeding brought on our behalf;

•

any action asserting a claim of breach of a fiduciary duty owed by, or otherwise wrongdoing by, any of our directors, officers or other employees to us or our stockholders;

•

any action arising pursuant to any provision of the Delaware General Corporation Law (“DGCL”), our certificate of incorporation or bylaws;

•

any action to interpret, apply, enforce or determine the validity of our certificate of incorporation or bylaws; and

•

any other action asserting a claim that is governed by the internal affairs doctrine shall be in a state or federal court located within the State of Delaware.

However, notwithstanding the exclusive forum provisions, our bylaws explicitly state that they would not preclude the filing of claims brought to enforce any liability or duty created under federal securities laws, including the Exchange Act or the Securities Act.

Although we believe these provisions benefit us by providing increased consistency in the application of Delaware law for the specified types of actions and proceedings, the provisions may have the effect of discouraging lawsuits against us or our directors and officers.

In addition, our bylaws provide that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act.

TABLE OF CONTENTS

Registration Rights Agreement

We are party to an amended and restated registration rights agreement with ChaSerg Technology Sponsor LLC (the “Sponsor”) and certain other holders party thereto (the “Existing Holders”) (as amended and restated, the “Registration Rights Agreement”). Under the Registration Rights Agreement, we were required to register for resale our common stock issuable for (i) shares of common stock held by any Existing Holders immediately following the closing of the business combination in March 2020, (ii) any of the 640,000 units issued in private placement transactions by us in October 2018 and (iii) any other equity securities of ours issued or issuable with respect to any securities referenced in clauses (i) and (ii) above by way of a stock dividend or stock split or in connection with a combination of shares, recapitalization, merger, consolidation or reorganization (collectively, “Registrable Securities”).

The holders of a majority-in-interest of the Registrable Securities held by the Existing Holders and any of their permitted transferees were entitled to demand that we register the resale of such securities; provided, however, that we are not required to effect an underwritten offering for any resale of Registrable Securities on a Registration Statement on Form S-3 unless such underwritten offering is reasonably expected to result in gross proceeds in excess of $10 million.

The Existing Holders and their permitted transferees also have certain “piggy-back” registration rights with respect to registration statements and rights to require us to register for resale such securities. We will bear the expenses incurred in connection with the filing of any such registration statements.

Stockholders’ Agreement

On November 13, 2019, ChaSerg Technology Acquisition Corp., the Sponsor, Benhamou Global Ventures, GDB International Investment Limited, GDD International Holding Company, Leonard Livschitz, Victoria Livschitz and Automated Systems Holdings Limited (“ASL”) (together with any individuals or entities that are signatories thereto or become party to the agreement, the “Voting Parties”) entered into a Stockholders’ Agreement, pursuant to which, among other things, the Voting Parties agreed (i) to take all necessary action to cause our board of directors to be comprised of eight directors, (ii) subject to certain share ownership thresholds, to grant each of ASL and the Sponsor rights to designate two directors for election to our board of directors (and the Voting Parties will vote in favor of such designees), (iii) to designate our chief executive officer for election to our board of directors, and (iv) to designate three unaffiliated designates for election to our board of directors.
