FATH Fathom Digital Manufacturing Corporation

RISK FACTORS

An investment in our securities involves a high degree of risk. You should carefully consider the risks described below before making an investment decision. Our business, prospects, financial condition, or operating results could be harmed by any of these risks, as well as other risks not known to us or that we consider immaterial as of the date of this prospectus. The trading price of our securities could decline due to any of these risks, and, as a result, you may lose all or part of your investment. Our actual results may differ materially from any future results expressed or implied by such forward-looking statements as a result of various factors, including, but not limited to, those discussed in the sections of this prospectus entitled “Cautionary Note Regarding Forward-Looking Statements” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Business Risks

We face significant competition and expect to face increasing competition in many aspects of our business, which could cause our operating results to suffer.

The digital manufacturing industry in which we operate is fragmented and highly competitive. We compete for customers with a wide variety of custom parts manufacturers and methods. Some of our current and potential competitors include captive in-house production capabilities, other custom parts manufacturers, brokers of custom parts and additive manufacturing vendors, including those utilizing 3D printing processes. Moreover, some of our existing and potential competitors are researching, designing, developing and marketing other types of products and manufacturing capabilities. We also expect that future competition may arise from the development or improvement of allied or related techniques for digital manufacturing, including from the issuance of patents to other companies that may inhibit our ability to compete effectively. Furthermore, our competitors may attempt to adopt and improve upon key aspects of our business model, such as development of technology that automates much of the manual labor conventionally required to quote and manufacture custom parts, implementation of interactive web-based and automated user interface and quoting systems and/or building scalable operating models specifically designed for efficient custom parts production. Third-party Computer Aided Design (“CAD”) software companies may develop software that mold-makers, injection molders and CNC machine shops could use to compete with our business model. Additive manufacturers may develop stronger, higher temperature resins or introduce other improvements that could more effectively compete with us on part quality. We may also, from time to time, establish alliances or relationships with other competitors or potential competitors, including 3D printer Original Equipment Manufacturers (“OEMs”). To the extent companies terminate such relationships and establish alliances and relationships with our competitors, our business could be harmed.

Existing and potential competitors may have substantially greater financial, technical, marketing and sales, manufacturing, distribution and other resources and name recognition than us, as well as experience and expertise in intellectual property rights, any of which may enable them to compete effectively against us. For example, a number of companies that possess substantial resources have announced that they are beginning digital manufacturing initiatives, which will further strengthen the competition we face.

Though we plan to continue to expend resources to develop new technologies, processes and manufacturing capabilities, we cannot assure you that we will be able to maintain our current competitive position or continue to compete successfully against current and future sources of competition. Our challenge in developing new business opportunities is identifying custom parts for which our automated quotation and digital manufacturing processes offer an attractive value proposition, and we may not be able to identify any new custom parts categories with favorable economics similar to our existing offerings. If we do not keep pace with technological change, demand for our offerings may decline and our operating results may suffer.

17

Our success depends on our ability to deliver on-demand manufacturing capabilities and custom parts that meet the needs of our customers and to effectively respond to changes in our industry.

We derive almost all of our revenue from the manufacture and sale to our customers of quick-turn, low volume custom parts for prototyping, support of internal manufacturing and limited quantity product release up to mid volume production requirements. Our business has been and, we believe, will continue to be, affected by changes in our customers’ new product and product line introductions, requirements and preferences, rapid technological change and the emergence of new standards and practices, any of which could render our technology and manufacturing capabilities less attractive, uneconomical or obsolete. To the extent that our customers’ need for quick-turn to mid-volume production parts decreases significantly for any reason, it would likely have a material adverse effect on our business and operating results and harm our competitive position. In addition, CAD simulation and other technologies may reduce the demand for physical prototype parts. Therefore, we believe that to remain competitive, we must continually expend resources to enhance and improve our technology and manufacturing capabilities.

In particular, we plan to increase our research and development efforts and to continue to focus a significant portion of those efforts to further develop our technology in areas such as our interactive project management platform and manufacturing processes, technology offerings and broaden the range of parts that we are able to manufacture. We believe successful execution of this part of our business plan is critical for our ability to compete in our industry and grow our business, and there are no guarantees we will be able to do so in a timely fashion, or at all. Broadening the range of parts and technologies that we are able to manufacture and offer is of particular importance because limitations in manufacturability are the primary reason we are not able to fulfill many quotation requests. There are no guarantees that the resources we devote to executing on this aspect of our business plan will improve our business and operating results or result in increased demand for our custom parts and manufacturing capabilities. Failures in this area could adversely impact our operating results and harm our reputation and brands. Even if we are successful in executing in this area, our industry is subject to rapid and significant technological change, and our competitors may develop new technologies and manufacturing capabilities that are superior to ours.

Any failure to properly meet the needs of our customers or respond to changes in our industry on a cost-effective and timely basis, or at all, would likely have a material adverse effect on our business and operating results and harm our competitive position.

Our failure to meet our customers’ expectations regarding quick turnaround time, price or quality could adversely affect our business and results of operations.

We believe many of our customers are facing increased pressure from global competitors to be first to market with their finished products, often resulting in a need for quick turnaround of custom parts. We believe our ability to quickly quote, manufacture and ship custom parts has been an important factor in our results to date. There are no guarantees we will be able to meet customers’ increasing expectations regarding quick turnaround time. If we fail to meet our customers’ expectations regarding turnaround time in any given period, our business and results of operations will likely suffer.

Demand for our custom parts and manufacturing capabilities is sensitive to price. We believe our competitive pricing has been an important factor in our results to date. Therefore, changes in our pricing strategies can have a significant impact on our business and ability to generate revenue. Many factors, including our production and personnel costs and our competitors’ pricing and marketing strategies, can significantly impact our pricing strategies. If we fail to meet our customers’ price expectations in any given period, demand for our custom parts and manufacturing capabilities could be negatively impacted and our business and results of operations could suffer.

Most of our customers have a need for specific quality of quick-turn, on-demand custom parts. We believe our ability to create parts meeting our customers’ specifications and quality expectations is an important factor in

18

our results to date. We cannot assure you that we will be able to continue to consistently manufacture custom parts that achieve the production specifications and quality that our customers expect. If we fail to meet our customers’ specifications and quality expectations in any given period, demand for our custom parts and manufacturing capabilities could be negatively impacted and our business and results of operations could suffer.

The strength of our brands is important to our business, and any failure to maintain and enhance our brands would hurt our ability to retain and expand our customer base as well as further penetrate existing customers.

Because our custom parts and manufacturing capabilities are sold primarily through our website, the success of our business depends upon our ability to attract new and repeat customers to our website in order to increase business and grow our revenue. Customer awareness and the perceived value of our brands will depend largely on the success of our marketing efforts, as well as our ability to consistently provide quality custom parts within the required timeframes and positive customer experiences, which we may not do successfully. A primary component of our business strategy is the continued promotion and strengthening of our brands. We may choose to increase our branding expense materially, but we cannot be sure that this investment will be profitable. If we are unable to successfully maintain and enhance our brands, this could have a negative impact on our business and ability to generate revenue.

Sales efforts to large customers involve risks that may not be present or that are present to a lesser extent with respect to sales to smaller organizations.

Attracting and retaining business from large enterprise customers is an element of our business strategy. Sales to large customers involve risks that may not be present or that are present to a lesser extent with sales to smaller organizations, such as longer sales cycles, more complex customer requirements, substantial upfront sales costs, less predictability in completing some of our sales and extended payment terms. A number of factors influence the length and variability of our sales cycle, including the need to educate potential customers about the uses and benefits of our platform, the various technologies available and manufacturing capabilities, the longer period of time for large customers to evaluate and test our project management platform prior to making a purchase decision and placing an order, the discretionary nature of purchasing and budget cycles and the competitive nature of evaluation and purchasing approval processes. As a result, the length of our sales cycle, from identification of the opportunity to deal closure, may vary significantly from customer to customer, with sales to large enterprises typically taking longer to complete. Moreover, larger organizations may demand more customization, which would increase our upfront investment in the sales effort with no guarantee that these customers will seek to use our manufacturing capabilities widely enough across their organization to justify our substantial upfront investment. A portion of these customers may purchase our offerings on payment terms, requiring us to assume a credit risk for non-payment in the ordinary course of business. If we fail to effectively manage these risks associated with sales to large customers, our business, financial condition and results of operations may be affected.

Our business depends in part on our ability to process a large volume of new custom part designs from a diverse group of customers and successfully identify significant opportunities for our business based on those submissions.

We believe the volume of new custom part designs we process and the size and diversity of our customer base give us valuable insight into the needs of our prospective customers. We utilize this industry knowledge to determine where we should focus our development resources. If the number of new custom part designs we process or the size and diversity of our customer base decrease, our ability to successfully identify significant opportunities for our business and meet the needs of customers could be negatively impacted. In addition, even if we do continue to process a large number of new custom part designs and work with a significant and diverse customer base, there are no guarantees that any industry knowledge we extract from those interactions will be successfully utilized to help us identify significant business opportunities or better understand the needs of our existing or prospective customers.

19

Wage increases and pressure in certain geographies may prevent us from sustaining our competitive advantage and may reduce our profit margin.

Measures are being taken in the United States and globally to increase minimum wages, and there is a shortage of skilled labor in certain locations leading to increased wage pressure. Similarly, with an increased global focus on environmental, social and corporate-governance concerns and sustainability, input costs have been steadily rising. In addition, enhanced federally subsidized unemployment benefits during the ongoing COVID-19 pandemic may have been contributing to labor shortages at some of our facilities. Accordingly, we may need to increase the levels of labor compensation more rapidly than in the past to remain competitive in attracting and retaining the quality and amount of labor that our business requires. To the extent that we are not able to control or recoup wage increases through our pricing, wage increases may reduce our margins and cash flows, which could adversely affect our business.

The loss of one or more key members of our management team or personnel, or our failure to attract, integrate and retain additional personnel in the future, could harm our business and negatively affect our ability to successfully grow our business.

We are highly dependent upon the continued service and performance of the key members of our management team and other personnel. The loss of any of these individuals, each of whom is “at will” and may terminate his or her employment relationship with us at any time, could disrupt our operations and significantly delay or prevent the achievement of our business objectives. We believe that our future success will also depend in part on our continued ability to identify, hire, train and motivate qualified personnel. High demand exists for senior management and other key personnel (including technical, engineering, product, finance and sales personnel) in the digital manufacturing industry. A possible shortage of qualified individuals in the regions where we operate might require us to pay increased compensation to attract and retain key employees, thereby increasing our costs. In addition, we face intense competition for qualified individuals from numerous companies, many of whom have substantially greater financial and other resources and name recognition than us. We may be unable to attract and retain suitably qualified individuals who are capable of meeting our growing operational, managerial and other requirements, or we may be required to pay increased compensation in order to do so. For example, our failure to attract and retain shop floor employees may inhibit our ability to fulfill production orders for our customers. Our failure to attract, hire, integrate and retain qualified personnel could impair our ability to achieve our business objectives.

All of our employees are at-will employees, meaning that they may terminate their employment relationship with us at any time, and their knowledge of our business and industry would be extremely difficult to replace. We generally enter into non-competition agreements with our employees and certain consultants. These agreements prohibit our employees and applicable consultants from competing directly with us or working for our competitors or customers while they work for us, and in some cases, for a limited period after they cease working for us. We may be unable to enforce these agreements under the laws of the jurisdictions in which our employees and applicable consultants work and it may be difficult for us to restrict our competitors from benefiting from the expertise that our former employees or consultants developed while working for us. If we cannot demonstrate that our legally protectable interests will be harmed, we may be unable to prevent our competitors from benefiting from the expertise of our former employees or consultants and our ability to remain competitive may be diminished.

Our growth strategy relies on business acquisitions. We may not realize the anticipated benefits of such acquisitions, and any acquisition, strategic relationship, joint venture or investment could disrupt our business and harm our operating results and financial condition.

Our business and customer base have been built in part through organic growth, but also through acquisitions of businesses that increase market share in our current markets or expand into other markets, or broaden our technology, intellectual property or product line capabilities. We have completed 13 acquisitions

20

during the last three years, and we intend to continue to aggressively pursue attractive opportunities to enhance or expand our offerings through acquisitions, strategic relationships, joint ventures or investments that we believe may allow us to implement our growth strategy. For example, in December 2019, we acquired ICO Mold, LLC (“ICOMold”) to enable us to expand our existing Search Engine Optimization (“SEO”) and Search Engine Marketing (“SEM”) capabilities. During 2020 and 2021, we completed six acquisitions that added CNC machining to our manufacturing capabilities, and three acquisitions that added precision sheet metal fabrication to our offerings. We cannot forecast the number, timing or size of any future acquisitions or other similar strategic transactions, or the effect that any such transactions might have on our operating or financial results. We may not be able to successfully identify future acquisition opportunities or complete any such acquisitions if we cannot reach agreement on commercially favorable terms, if we lack sufficient resources to finance the transaction on our own and cannot obtain financing at a reasonable cost or if regulatory authorities prevent such transactions from being completed.

Although we have substantial experience engaging in these types of transactions, such transactions may be complex, time consuming and expensive, and may present numerous challenges and risks including:

Any one of these challenges or risks could impair our ability to realize any benefit from our acquisitions, strategic relationships, joint ventures or investments after we have expended resources on them, as well as divert our management’s attention. Any failure to successfully address these challenges or risks could disrupt our business and harm our operating results and financial condition. Moreover, any such transaction may not be viewed favorably by investors or other stakeholders.

If we proceed with a particular acquisition, we may have to use cash, issue new equity securities with dilutive effects on existing stockholders, incur indebtedness, assume contingent liabilities, or amortize assets or expenses in a manner that might have a material adverse effect on our financial condition and results of operations. Acquisitions will also require us to record certain acquisition-related costs and other items as current period expenses, which would have the effect of reducing our reported earnings in the period in which an acquisition is consummated. In addition, we could also face unknown liabilities or write-offs due to our acquisitions, which could result in a significant charge to our earnings in the period in which they occur. We will also be required to record any goodwill or other long-lived asset impairment charges in the periods in which they occur, which could result in a significant charge to our earnings in any such period.

Achieving the expected returns and synergies from future acquisitions will depend, in part, upon our ability to integrate the products and services, technology, administrative functions and personnel of these businesses into our offering lines in an efficient and effective manner. We cannot assure you that we will be able to do so, that

21

any acquired businesses will perform at levels and on the timelines anticipated by our management or that we will be able to realize these synergies. In addition, acquired technologies and intellectual property may be rendered obsolete or uneconomical by our own or our competitors’ technological advances. Management resources may also be diverted from operating our existing businesses to certain acquisition integration challenges. If we are unable to successfully integrate acquired businesses, our anticipated revenues and profits may be lower. Our profit margins may also be lower, or diluted, following the acquisition of companies whose profit margins are less than those of our existing businesses.

In addition, from time to time we may enter into negotiations for acquisitions, relationships, joint ventures or investments that are not ultimately consummated. These negotiations could result in significant diversion of management time, as well as substantial out-of-pocket costs.

If we are unable to manage our growth and expand our operations successfully, our reputation and brands may be damaged, and our business and results of operations may be harmed.

Over the past several years, we have experienced rapid growth. For example, we have grown from 44 full-time employees as of October 31, 2018 to 706 full-time employees as of December 31, 2021. We expect this growth to continue and the number of facilities from which we operate to increase in the future. Our ability to effectively manage our anticipated growth and expansion of our operations will require us to do, among other things, the following:

These enhancements and improvements will require significant capital expenditures and allocation of valuable management and employee resources. Furthermore, our growth has placed, and will continue to place, a strain on our operational, financial and management infrastructure. Our future financial performance and our ability to execute on our business plan will depend, in part, on our ability to effectively manage any future growth and expansion. There are no guarantees we will be able to do so in an efficient or timely manner, or at all. Our failure to effectively manage growth and expansion could have a material adverse effect on our business, results of operations, financial condition, prospects, reputation and brands, including impairing our ability to perform to our customers’ expectations.

We may not timely and effectively scale and adapt our existing technology, processes and infrastructure to meet the needs of our business.

A key element to our continued growth is the ability to quickly and efficiently quote an increasing number of customer submissions across geographic regions and to manufacture the related custom parts. This will require us to timely and effectively scale and adapt our existing technology, processes and infrastructure to meet the needs of our business. With respect to our website, project management platform and quoting technology, it may become increasingly difficult to maintain and improve their performance, especially during periods of heavy usage and as our solutions become more complex and our user traffic increases across geographic regions. Similarly, our manufacturing automation technology may not enable us to process the large numbers of unique designs and efficiently manufacture the related custom parts in a timely fashion to meet the needs of our customers as our business continues to grow. Any failure in our ability to timely and effectively scale and adapt our existing technology, processes and infrastructure could negatively impact our ability to retain existing customers and attract new customers, damage our reputation and brands, result in lost revenue, and otherwise substantially harm our business and results of operations.

22

We may require additional capital to support business growth, and this capital might not be available on acceptable terms, if at all. If we are unable to raise additional capital when needed, our financial condition could be adversely affected and we may not be able to execute our growth strategy.

We intend to continue to make acquisitions and other investments to support our business growth and may require additional funds to respond to business challenges, including the need to complement our growth strategy, increase market share in our current markets or expand into other markets, or broaden our technology, intellectual property or manufacturing capabilities. Accordingly, we may need to obtain equity or debt financings to secure additional funds. If we raise additional funds through future issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our common stock. The New Credit Agreement and any debt financing we secure in the future could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. We may not be able to obtain additional financing on terms favorable to us, if at all. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to support our business growth and to respond to business challenges could be significantly impaired, and our business may be adversely affected.

Numerous factors may cause us not to maintain the revenue growth that we have historically experienced.

Although our revenue has grown from $20.6 million for the year ended December 31, 2019 to $152.2 million for the year ended December 31, 2021, we may not be able to maintain our historical rate of revenue growth. We believe that our continued revenue growth will depend on many factors, a number of which are out of our control, including among others, our ability to:

We cannot assure you that we will be successful in addressing the factors above and continuing to grow our business and revenue.

Errors or defects in the software we use or custom parts we manufacture could cause us to incur additional costs, lose revenue and business opportunities, damage our reputation and expose us to potential liability.

The sophisticated software we use and the often complex custom parts we manufacture may contain errors, defects or other performance problems at any point in the life of the software or custom parts. If errors or defects are discovered in our current or future software or in the custom parts we manufacture for customers, we may not be able to correct them in a timely manner or provide an adequate response to our customers. We may therefore need to expend significant financial, technical and management resources, or divert some of our development

23

resources, in order to resolve or work around those errors or defects. We may also experience an increase in our service and warranty costs. Particularly in the medical sector, errors or defects in our software or custom parts we manufacture could lead to claims by patients against us and our customers and expose us to lawsuits that may damage our and our customers’ reputations. Claims may be made by individuals or by classes of users. Our product liability and related insurance policies may not apply or sufficiently cover any product liability lawsuit that arises from defective software we may use or the custom parts we manufacture. Customers such as our collaboration partners may also seek indemnification for third party claims allegedly arising from breaches of warranties under our collaboration agreements.

Errors, defects or other performance problems in the software we use or custom parts we manufacture may also result in the loss of, or delay in, the market acceptance of our platform and digital manufacturing capabilities. Such difficulties could also cause us to lose customers and, particularly in the case of our largest customers, the potentially substantial associated revenue which would have been generated by our sales to companies participating in our customer supply chains. Technical problems, or the loss of a customer with a particularly important national or global reputation, could also damage our own business reputation and cause us to lose new business opportunities.

Interruptions to or other problems with our website, project management platform, information technology systems, manufacturing processes or other operations could damage our reputation and brands and substantially harm our business and results of operations.

The satisfactory performance, reliability, consistency, security and availability of our website and interactive project management platform, information technology systems, manufacturing processes and other operations are critical to our reputation and brands, and to our ability to effectively service customers. Any interruptions or other problems that cause any of our website, interactive project management platform or information technology systems to malfunction or be unavailable, or negatively impact our manufacturing processes or other operations, may damage our reputation and brands, result in lost revenue, cause us to incur significant costs seeking to remedy the problem and otherwise substantially harm our business and results of operations.

A number of factors or events could cause such interruptions or problems, including among others: human and software errors, design faults, challenges associated with upgrades, changes or new facets of our business, power loss, telecommunication failures, fire, flood, extreme weather, political instability, acts of terrorism, war, break-ins and security breaches, contract disputes, labor strikes and other workforce-related issues, capacity constraints due to an unusually large number of customers and potential customers accessing our website or project management platform or ordering parts at the same time, and other similar events. These risks are augmented by the fact that our customers come to us largely for our quick-turn low to mid-volume manufacturing capabilities and that accessibility and turnaround speed are often of critical importance to these customers. We are dependent upon our facilities through which we satisfy all of our production demands and in which we house all of the computer hardware necessary to operate our website and systems as well as managerial, customer service, sales, marketing and other similar functions, and we have not identified alternatives to these facilities or established fully redundant systems in multiple locations. In addition, we are dependent in part on third parties for the implementation and maintenance of certain aspects of our communications and production systems, and therefore preventing, identifying and rectifying problems with these aspects of our systems is to a large extent outside of our control.

Moreover, the business interruption insurance that we carry may not be sufficient to compensate us for the potentially significant losses, including the potential harm to the future growth of our business that may result from interruptions in our offerings and manufacturing processes as a result of system failures.

24

If a natural or man-made disaster strikes any of our manufacturing facilities, we may be unable to manufacture our products for a substantial period of time and our sales will decline.

We manufacture all of our products in 12 manufacturing facilities located in the United States. These facilities and the manufacturing equipment we use would be costly to replace if damaged by a natural or man-made disaster, and could require substantial lead time to repair or replace. Our facilities may be harmed by natural or man-made disasters, including, without limitation, earthquakes, floods, tornadoes, fires, hurricanes, tsunamis, nuclear disasters, terrorist attacks, or as a result of the ongoing COVID-19 pandemic. In the event any of our facilities are affected by a disaster, we may:

Although we possess insurance for damage to our property and the disruption of our business from casualties, this insurance may not be sufficient to cover all of our potential losses and may not continue to be available to us on acceptable terms, or at all.

If our present single or limited source suppliers become unavailable or inadequate, our customer relationships, results of operations and financial condition may be adversely affected.

We acquire substantially all of the manufacturing equipment and certain of our materials that are critical to the ongoing operation and future growth of our business from third parties. We do not have long-term supply contracts with any of our suppliers and operate on a purchase-order basis. While most manufacturing equipment and materials for our products are available from multiple suppliers, certain of those items are only available from single or limited sources. Should any of our present single or limited source suppliers for manufacturing equipment or materials become unavailable or inadequate, or impose terms unacceptable to us such as increased pricing terms, we could be required to spend a significant amount of time and expense to develop alternate sources of supply, and we may not be successful in doing so on terms acceptable to us, or at all. Natural disasters, such as hurricanes or tornadoes, may affect our supply of materials, particularly resins, from time to time, and we may purchase larger amounts of certain materials in anticipation of future shortages or increases in pricing. In addition, if we were unable to find a suitable supplier for a particular type of manufacturing equipment or material, we could be required to modify our existing manufacturing processes and offerings to accommodate the situation. As a result, the loss of a single or limited source supplier could adversely affect our relationship with our customers and our results of operations and financial condition.

We are subject to payment-related risks.

We accept payments using a variety of methods, including credit card, customer invoicing, physical bank check and payment upon delivery. As we offer new payment options to our customers, we may be subject to additional regulations, compliance requirements and fraud risk. For certain payment methods, including credit and debit cards, we pay interchange and other fees, which may increase over time and raise our operating costs and lower profitability. We rely on third parties to provide payment processing services, including the processing of credit cards, debit cards or electronic checks, and it could disrupt our business if these companies become unwilling or unable to provide these services to us. We are also subject to payment card association operating rules, certification requirements and rules governing electronic funds transfers, which could change or be

25

reinterpreted to make it difficult or impossible for us to comply. If we fail to comply with these rules or requirements, we may be subject to fines and higher transaction fees and lose our ability to accept credit and debit card payments from our customers, process electronic funds transfers, or facilitate other types of online payments, and our business and operating results could be adversely affected.

Workplace accidents or environmental damage could result in substantial remedial obligations and damage to our reputation.

Accidents or other incidents that occur at our manufacturing and other facilities or involve our personnel or operations could result in claims for damages against us. In addition, in the event we are found to be financially responsible, as a result of environmental or other laws or by court order, for environmental damages alleged to have been caused by us or occurring on our premises, we could be required to pay substantial monetary damages or undertake expensive remedial obligations. The amount of any costs, including fines or damages payments that we might incur under such circumstances, could substantially exceed any insurance we have to cover such losses. Any of these events, alone or in combination, could have a material adverse effect on our business, financial condition and results of operations and could adversely affect our reputation.

Interruptions, delays in service or inability to increase capacity at third-party data center facilities could adversely affect our business and reputation.

Our business, brands, reputation and ability to attract and retain customers depend upon the satisfactory performance, reliability and availability of our project management platform, depend upon the availability of the internet and our third-party service providers. We rely on third party data center facilities operated by Amazon Web Services (“AWS”), Ace Cloud Hosting (“Ace”), and Right Networks (“Right Networks”) to host our main servers. We do not control the operation of any of AWS’, Ace’s or Right Networks’ data center hosting facilities, and they may be subject to damage or interruption from earthquakes, floods, fires, power loss, telecommunications failures, terrorist attacks and similar events. They may also be subject to interruptions due to system failures, computer viruses, software errors or subject to breaches of computer hardware and software security, break-ins, sabotage, intentional acts of vandalism and similar misconduct. And while we rely on service level agreements with our hosting providers, if they do not properly maintain their infrastructure or if they incur unplanned outages, our customers may experience performance issues or unexpected interruptions and we may not meet our service level agreement terms with our customers. We have experienced, and expect that in the future we may experience interruptions, delays and outages in service and availability from time to time due to a variety of factors, including infrastructure changes, human or software errors, website hosting disruptions and capacity constraints. These and other similar events beyond our control could negatively affect the use, functionality or availability of our services.

Any damage to, or failure of, our systems, or those of our third-party providers, could interrupt or hinder the use or functionality of our website or project management platform. Resulting impairment of or interruptions of our business may reduce revenue, subject us to claims and litigation, cause customers to terminate their contracts and adversely affect our ability to attract new customers. If we are forced to switch hosting facilities for our main servers, we may not be successful in finding an alternative service provider on acceptable terms or in hosting the computer servers ourselves. Our business will also be harmed if customers and potential customers believe our systems are unreliable.

Industry Risks

The COVID-19 pandemic has adversely affected and could in the future adversely affect our business and results of operations. The duration and extent to which it will continue to adversely impact our business and results of operations remains uncertain and could be material. Further, the COVID-19 outbreak has caused severe disruptions in the U.S. and global economy and financial markets and could potentially create widespread business continuity issues of yet unknown magnitude or duration.

The COVID-19 pandemic has resulted in a widespread public health crisis and numerous significant disease control measures being taken to limit its spread, including travel bans and restrictions, quarantines, shelter-in-place orders and shutdowns. These measures have materially impacted and may impact our workforce and operations, the operations of our customers, and those of our respective vendors and suppliers. Our operations are located in the United States, and domestic and global measures taken in effort to contain the pandemic has caused disruptions at some of our manufacturing operations and facilities as well as supplier facilities. Further such disruptions could occur in the future, including outbreaks of other highly infectious or contagious disease and any such disruptions could materially adversely affect our business. The impact of the pandemic on our business has included and could in the future include:

The global spread of COVID-19 also has created significant macroeconomic uncertainty, volatility and disruption, which may adversely affect our and our customers’ and suppliers’ liquidity, cost of capital and ability to access the capital markets. Even after the COVID-19 pandemic has subsided, we may continue to experience adverse impacts to our business as a result of the pandemic’s global economic impact, including any recession, economic downturn, government spending cuts, tightening of credit markets or increased unemployment that has occurred or may occur in the future, which could cause our customers and potential customers to postpone or reduce spending on our manufacturing services and solutions.

27

If demand for our offerings and manufacturing capabilities does not grow as expected, or if market adoption of digital manufacturing does not continue to develop, or develops more slowly than expected, our revenues may stagnate or decline and our business may be adversely affected.

The industrial manufacturing market, which today is dominated by conventional manufacturing processes that do not involve digital manufacturing technology, is undergoing a shift towards digital manufacturing. We may not be able to develop effective strategies to raise awareness among potential customers of the benefits of digital manufacturing technologies or our offerings and manufacturing capabilities may not address the specific needs or provide the level of functionality required by potential customers to encourage the continuation of this shift towards digital manufacturing. If digital manufacturing technology does not continue to gain broader market acceptance as an alternative to conventional manufacturing processes, or if the marketplace adopts digital manufacturing technologies and capacities developed by our competitors, we may not be able to increase or sustain the level of sales of our offerings and our operating results would be adversely affected as a result.

Customers may use our digital manufacturing offerings to produce parts that could be used in a harmful way or could otherwise be dangerous. For example, there have been news reports that 3D printers were used to print guns or other weapons. We have little, if any, control or knowledge over the parts we manufacture for our customers using our offerings, and it may be difficult, if not impossible, for us to monitor and prevent customers from having certain components of weapons or other dangerous objects manufactured with our services. While we have never digitally manufactured weapons for customers, there can be no assurance that we will not be held liable if someone were injured or killed by a weapon or other dangerous object containing a component part or parts manufactured for a customer using one of our offerings.

Because the digital manufacturing market is rapidly evolving, forecasts of market growth in this prospectus may not be accurate.

Market opportunity estimates and growth forecasts included in this prospectus are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. The forecasts and estimates in this prospectus relating to the expected size and growth of the markets for digital manufacturing technology and other markets in which we participate may prove to be inaccurate. Even if these markets experience the forecasted growth described in this prospectus, we may not grow our business at similar rates, or at all. Our future growth is subject to many factors, including continued market adoption of our offerings, which is subject to many risks and uncertainties. Accordingly, the forecasts and estimates of market size and growth described in this prospectus should not be taken as indicative of our future growth. In addition, these forecasts do not consider the impact of the ongoing global COVID-19 pandemic, and we cannot assure you that these forecasts will not be materially and adversely affected as a result.

Unfavorable global economic conditions and changes, including changes in inflation, interest rates and geopolitical matters, could adversely affect our business, financial condition or results of operations.

Our results of operations could be adversely affected by general economic conditions in the global economy and in the global financial markets, including changes in inflation, interest rates and overall economic conditions and uncertainties. We have experienced pricing increases from our suppliers and we have increased compensation to our employees to help ensure employee retention. To the extent inflation or other factors increase our business costs, it may not be feasible to pass price increases on to our customers or offset higher costs through manufacturing efficiencies. Inflation could also adversely affect the ability of our customers to purchase our products and higher interest rates could adversely affect the ability of our customers to invest in product innovation and development that generate demand for our custom parts. An economic downturn could result in a variety of risks to our business, including weakened demand for our products and our inability to raise additional capital when needed on acceptable terms, if at all. A weak or declining economy could also result in further constraints on our suppliers or cause future customers to delay making payments for our products. Any of the foregoing could harm our business and we cannot anticipate all of the ways in which the current economic climate and financial market conditions could adversely impact our business.

28

In addition, the ongoing trade war between the United States and China may impact the cost of raw materials, finished products or other materials used in our offerings and our ability to sell our offerings in China. Other changes in U.S. social, political, regulatory, and economic conditions or in laws and policies governing foreign trade, manufacturing, development and investment could also adversely affect our business. We could experience interruptions in production due to the processing of customs formalities or reduced customer spending in the wake of weaker economic performance. If global economic conditions remain volatile for a prolonged period our results of operations could be adversely affected.

Intellectual Property and Infrastructure-Related Risks

We may not be able to adequately protect or enforce our intellectual property rights, which could impair our competitive position.

Our success and future revenue growth will depend, in part, on our ability to protect our intellectual property. We rely primarily on patents, licenses, trademarks and trade secrets, as well as non-disclosure agreements and other methods, to protect our proprietary technologies and processes globally. Despite our efforts to protect our proprietary technologies and processes, it is possible that competitors or other unauthorized third parties may obtain, copy, use or disclose our technologies and processes or invent around our patents. We cannot assure you that any of our existing or future patents will not be challenged or invalidated in court or patent office proceedings that could be time-consuming, expensive and distract us from operating our business. In addition, competitors could circumvent our patents by inventing around them. As such, any rights granted under these patents may not provide us with meaningful protection. We may not be able to obtain foreign patents corresponding to our United States patents. Even if foreign patents are granted, effective enforcement in foreign countries may not be available. If our patents and other intellectual property do not adequately protect our proprietary technology, our competitors may be able to offer product lines similar to ours. Our competitors may also be able to develop similar technology independently or design around our patents. Any of the foregoing events would lead to increased competition and lower revenue or gross margin, which would adversely affect our net income.

We may incur substantial costs enforcing or acquiring intellectual property rights and defending against third-party claims as a result of litigation or other proceedings. Our failure to expand our intellectual property portfolio could adversely affect the growth of our business and results of operations.

We may incur substantial expense and costs in protecting, enforcing and defending our intellectual property rights against third parties. Intellectual property disputes may be costly and can be disruptive to our business operations by diverting attention and energies of management and key technical personnel and by increasing our costs of doing business. Third-party intellectual property claims asserted against us could subject us to significant liabilities, require us to enter into royalty and licensing arrangements on unfavorable terms, prevent us from providing our offerings to customers, subject us to injunctions prohibiting or restricting our sale of our offerings, or require us to redesign our offerings, causing severe disruptions to our operations or the marketplaces in which we compete or require us to satisfy indemnification commitments with our customers, including contractual provisions under various license arrangements. In addition, we may incur significant costs in acquiring the necessary third-party intellectual property rights for use in our offerings. Any of these could have an adverse effect on our business and financial condition.

Patent applications in the United States and most other countries are confidential for a period of time until they are published, and the publication of discoveries in scientific or patent literature typically lags actual discoveries by several months or more. As a result, the nature of claims contained in unpublished patent filings around the world is unknown to us, and we cannot be certain that we were the first to conceive inventions covered by our patents or patent applications or that we were the first to file patent applications covering such inventions. Furthermore, it is not possible to know in which countries patent holders may choose to extend their filings under the Patent Cooperation Treaty or other mechanisms.

29

In addition, we may be subject to intellectual property infringement claims from individuals, vendors and other companies, including those that are in the business of asserting patents, but are not commercializing products or services in the field of digital manufacturing, or our customers may seek to invoke indemnification obligations to involve us in such intellectual property infringement claims. Furthermore, although we maintain certain procedures to screen custom parts we manufacture on behalf of customers for infringement on the intellectual property rights of others, we cannot be certain that our procedures will be effective in preventing any such infringement. Any third-party lawsuits or other assertion to which we are subject, alleging infringement of trademarks, patents, trade secrets or other intellectual property rights either by us or by our customers may have a significant adverse effect on our financial condition.

Cybersecurity risks and cyber incidents, including cyber-attacks, could adversely affect our business by causing a disruption to our operations, a compromise or corruption of our confidential information and confidential information in our possession and damage to our business relationships, any of which could negatively impact our business, financial condition and operating results.

There has been an increase in the frequency and sophistication of the cyber and security threats we face, with attacks ranging from those common to businesses generally to those that are more advanced and persistent, which may target us due to our substantial reliance on information technology or otherwise. Cyber-attacks and other security threats could originate from a wide variety of sources, including cyber criminals, nation state hackers, hacktivists and other outside parties. As a result of the generally increasing frequency and sophistication of cyber-attacks, and our substantial reliance on technology, we may face a heightened risk of a security breach or disruption with respect to sensitive information resulting from an attack by computer hackers, foreign governments or cyber terrorists.

The operation of our business is dependent on computer hardware and software systems, as well as data processing systems and the secure processing, storage and transmission of information, which are vulnerable to security breaches and cyber incidents. A cyber incident is considered to be any adverse event that threatens the confidentiality, integrity or availability of our information resources. These incidents may be an intentional attack or an unintentional event and could involve gaining unauthorized access to our information systems for purposes of misappropriating assets, stealing confidential information, corrupting data or causing operational disruption. In addition, we and our employees may be the target of fraudulent emails or other targeted attempts to gain unauthorized access to proprietary or other sensitive information. The result of these incidents may include disrupted operations, misstated or unreliable financial data, fraudulent transfers or requests for transfers of money, liability for stolen information, increased cybersecurity protection and insurance costs, litigation and damage to our business relationships, causing our business and results of operations to suffer. Our reliance on information technology is substantial, and accordingly the risks posed to our information systems, both internal and those provided by third-party service providers are critical. We have implemented processes, procedures and internal controls designed to mitigate cybersecurity risks and cyber intrusions and rely on industry accepted security measures and technology to securely maintain confidential and proprietary information maintained on our information systems; however, these measures, as well as our increased awareness of the nature and extent of a risk of a cyber-incident, do not guarantee that a cyber-incident will not occur and/or that our financial results, operations or confidential information will not be negatively impacted by such an incident, especially because the cyber-incident techniques change frequently or are not recognized until launched and because cyber-incidents can originate from a wide variety of sources.

Those risks are exacerbated by the rapidly increasing volume of highly sensitive data, including our and our customers’ proprietary business information and intellectual property, and personally identifiable information of our employees and customers, that we collect and store in our data centers and on our networks. The secure processing, maintenance and transmission of this information are critical to our operations. A significant actual or potential theft, loss, corruption, exposure, fraudulent use or misuse of employee, customer or other personally identifiable or our or our customers’ proprietary business data, whether by third parties or as a result of employee malfeasance (or the negligence or malfeasance of third party service providers that have access to such

30

confidential information) or otherwise, non-compliance with our contractual or other legal obligations regarding such data or intellectual property or a violation of our privacy and security policies with respect to such data could result in significant remediation and other costs, fines, litigation or regulatory actions against us and significant reputational harm.

Our proprietary digital manufacturing software contains third-party open-source software components. Our use of such open-source software may expose us to additional risks and harm our intellectual property and failure to comply with the terms of the underlying open-source software licenses could restrict our ability to sell our offerings.

Our proprietary digital manufacturing software contains components that are licensed under so-called “open source,” “free” or other similar licenses. Open source software is made available to the general public on an “as-is” basis under the terms of a non-negotiable license. We currently combine our proprietary software with open source software, but not in a manner that we believe requires the release of the source code of our proprietary software to the public. We do not plan to integrate our proprietary software with open source software in ways that would require the release of the source code of our proprietary software to the public; however, our use of open source software may entail greater risks than use of third-party commercial software. Open source licensors generally do not provide warranties or other contractual protections regarding infringement claims or the quality of the code. In addition, if we combine our proprietary software with open source software in a certain manner, we could, under certain open source licenses, be required to release to the public or remove the source code of our proprietary software. As is standard practice among technology companies, Fathom OpCo leverages open source software in the development of its internal software. Open source software is commonly used as a foundation to which Fathom OpCo develops upon, allowing us to customize the software based on the specific needs of Fathom. This approach enables faster development of high quality software. We may also face claims alleging noncompliance with open source license terms or infringement or misappropriation of proprietary software. These claims could result in litigation, require us to purchase a costly license or remove the open source software. In addition, if the license terms for open source software that we use change, we may be forced to re-engineer our solutions, incur additional costs or discontinue the sale of certain of our offerings if re-engineering could not be accomplished on a timely basis. Although we monitor our use of open source software to avoid subjecting our offerings to unintended conditions, there is a risk that these licenses could be construed in a way that could impose unanticipated conditions or restrictions on our ability to commercialize our offerings. We cannot guarantee that we have incorporated open source software in our proprietary software in a manner that will not subject us to liability or in a manner that is consistent with our current policies and procedures.

Compliance-Related Risks

Government regulation of the Internet and e-commerce is evolving, and unfavorable changes or failure by us to comply with these regulations could substantially harm our business and results of operations.

We are subject to general business regulations and laws as well as regulations and laws specifically governing the Internet and e-commerce. Existing and future laws and regulations may impede the growth of the Internet or other online services. These regulations and laws may cover taxation, restrictions on imports and exports, customs, tariffs, user privacy, data protection, pricing, content, copyrights, distribution, electronic contracts and other communications, consumer protection, the provision of online payment services, broadband residential Internet access and the characteristics and quality of the types of custom parts we manufacture or may manufacture in the future. It is not clear how existing laws governing issues such as property use and ownership, sales and other taxes, fraud, libel and personal privacy apply to the Internet and e-commerce, especially where these laws were adopted prior to the advent of the Internet and do not contemplate or address the unique issues raised by the Internet or e-commerce. Those laws that do reference the Internet are being interpreted by the courts and their applicability and reach are therefore uncertain. The costs of compliance with these regulations may increase in the future as a result of changes in the regulations or the interpretation of them. Further, any

31

failures on our part to comply with these regulations may subject us to significant liabilities. Those current and future laws and regulations or unfavorable resolution of these issues may substantially harm our business and results of operations.

Aspects of our business are subject to privacy, data use and data security regulations, which may impact the way we use data to target customers.

Privacy and security laws and regulations may limit the use and disclosure of certain information and require us to adopt certain cybersecurity and data handling practices that may affect our ability to effectively market our manufacturing capabilities to current, past or prospective customers. In many jurisdictions consumers must be notified in the event of a data security breach, and such notification requirements continue to increase in scope and cost. The changing privacy laws in the United States, Europe and elsewhere—including the General Data Protection Regulation (GDPR) in the European Union, which became effective May 25, 2018, and the California Consumer Privacy Act of 2018, which was enacted on June 28, 2018 and became effective on January 1, 2020—create new individual privacy rights and impose increased obligations, including disclosure obligations, on companies handling personal data. The impact of these continuously evolving laws and regulations could have a material adverse effect on the way we use data to digitally market and pursue our customers.

Our business involves the use of hazardous materials, and we and our suppliers must comply with environmental, health and safety laws and regulations, which can be expensive and restrict how we do business.

Our business involves the controlled storage, use and disposal of hazardous materials. We and our suppliers are subject to federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of these hazardous materials. Although we believe that the safety procedures utilized by us and our suppliers for handling and disposing of these materials comply with the standards prescribed by these laws and regulations, we cannot eliminate the risk of accidental contamination or injury from these materials. In the event of an accident, federal, state or local authorities may curtail the use of these materials and interrupt our business operations. We do not currently maintain hazardous materials insurance coverage. If we are subject to any liability as a result of activities involving hazardous materials, our business and financial condition may be adversely affected and our reputation and brands may be harmed.

If we are unable to meet regulatory quality standards applicable to our manufacturing and quality processes for the parts we manufacture, our business, financial condition or operating results could be harmed.

As a manufacturer of CNC-machined and injection-molded custom parts, we conform to certain international standards, including International Organization for Standardization, or ISO, 9001:2015 for our injection molding facilities and the AS9100:2016 standard for our CNC-machining facilities in Hartland, WI, Pflugerville, TX, Tempe, AZ, Newark, NY. We conform to the ISO 9001:2015 standard for our plastics manufacturing and the AS9100:2016 standard for our metals manufacturing in Hartland, WI, Pflugerville, TX, Tempe, AZ, and Newark, NY. We conform to the ISO 9001:2015 for our sheet metal custom parts and the AS9100:2016 standards for our CNC-machined custom parts in Hartland, WI, Pflugerville, TX, Tempe, AZ, and Newark, NY. We also conform to international standard ISO 9001:2015 at our manufacturing facilities in Hartland, WI, Oakland, CA, Newark, NY, Pflugerville, TX, Denver, CO, Round Rock, TX, Tempe, AZ, Miami Lakes, FL, and Elk Grove, IL. We conform to the NIST 800-171 standard at our facilities in Oakland, CA and Tempe, AZ. We conform to the ITAR standard at our facilities in Hartland, WI, Oakland, CA, Ithaca, NY, Denver, CO, Tempe, AZ, and Newark, NY. Additionally, we conform to international standard ISO 13485 at our manufacturing facilities in Round Rock, TX and Miami Lakes, FL. If any system inspection reveals that we are not in compliance with applicable standards, registrars may take action against us, including issuing a corrective action request or discontinuing our certifications. If any of these actions were to occur, it could harm our reputation as well as our business, financial condition and operating results.

32

We are subject to environmental, health and safety laws and regulations related to our operations and the use of our digital manufacturing systems and consumable materials, which could subject us to compliance costs and/or potential liability in the event of non-compliance.

We are subject to environmental laws and regulations governing our manufacturing operations, including, but not limited to, emissions into the air and water and the use, handling, disposal and remediation of hazardous substances. A certain risk of environmental liability is inherent in our production activities. These laws and regulations govern, among other things, the generation, use, storage, registration, handling and disposal of chemicals and waste materials, the emission and discharge of hazardous materials into the ground, air or water, the cleanup of contaminated sites, including any contamination that results from spills due to our failure to properly dispose of chemicals and other waste materials, and the health and safety of our employees. Under these laws, regulations and requirements, we could also be subject to liability for improper disposal of chemicals and waste materials. Accidents or other incidents that occur at our facilities or involve our personnel or operations could result in claims for damages against us. In the event we are found to be financially responsible, as a result of environmental or other laws or by court order, for environmental damages alleged to have been caused by us or occurring on our premises, we could be required to pay substantial monetary damages or undertake extensive remedial obligations. If our operations fail to comply with such laws or regulations, we may be subject to fines and other civil, administrative or criminal sanctions, including the revocation of permits and licenses necessary to continue our business activities. In addition, we may be required to pay damages or civil judgments in respect of third-party claims, including those relating to personal injury (including exposure to hazardous substances that we generate, use, store, handle, transport, manufacture or dispose of), property damage or contribution claims. Some environmental laws allow for strict and joint and several liabilities for remediation costs, regardless of fault. We may be identified as a potentially responsible party under such laws. The amount of any costs, including fines or damages payments that we might incur under such circumstances, could substantially exceed any insurance we have to cover such losses. Any of these events, alone or in combination, could have a material adverse effect on our business, financial condition and results of operations and could adversely affect our reputation.

The cost of complying with current and future environmental, health and safety laws applicable to our operations, or the liabilities arising from past releases of, or exposure to, hazardous substances, may result in future expenditures. Any of these developments, alone or in combination, could have an adverse effect on our business, financial condition and results of operations.

We are subject to anti-corruption laws, trade controls, economic sanctions and similar laws and regulations. Our failure to comply with these laws and regulations could subject us to civil, criminal and administrative penalties and harm our reputation.

We service customers located in a number of countries throughout the world. Doing business with foreign customers subjects us to U.S. and other anti-corruption laws and regulations imposed by governments around the world with jurisdiction over such commerce with foreign customers, including the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act 2010, as well as the laws of the countries where we do business. Failure to comply with these anti-corruption laws and regulations could subject us to civil, criminal, and administrative penalties and harm our reputation. We are also subject to various U.S., international, and regional trade laws, including trade and economic sanctions and export controls, imposed by governments around the world with jurisdiction over our commerce with foreign customers. We are also subject to embargoes, sanctions, and trade and export controls imposed by the U.S. and other governments restricting or prohibiting sales to or transactions with specific persons or jurisdictions or the provision of certain items, based on their classification, to certain jurisdictions or persons or for certain end use purposes. Failure to comply with these embargoes, sanctions, and trade and export controls could subject us to civil, criminal and administrative penalties and harm our reputation. These embargoes, sanctions, and trade and export controls can change rapidly with little to no notice, and therefore, our current and future offerings could become subject to heightened restrictions, which could increase our compliance costs and our risks of potential non-compliance in these areas.

Risks of Being a Public Company

Our management team has limited experience managing a public company.

Most members of our management team have limited experience managing a publicly traded company, interacting with public company investors and complying with the increasingly complex laws pertaining to public companies. Our management team may not successfully or efficiently manage our transition to being a public company that is subject to significant regulatory oversight and reporting obligations under the federal securities laws and the continuous scrutiny of securities analysts and investors. These new obligations and constituents will require significant attention from our senior management and could divert their attention away from the day-to-day management of our business, which could harm our business, results of operations and financial condition.

The requirements of being a public company may strain our resources, divert management’s attention and affect its ability to attract and retain qualified board members.

As a public company listed in the United States, we are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”) and any rules promulgated thereunder, as well as the rules of NYSE. The requirements of these rules and regulations increase our legal and financial compliance costs, make some activities more difficult, time-consuming or costly, and increase demand on its systems and resources. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal controls for financial reporting. In order to maintain and, if required, improve our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight will be required and, as a result, management’s attention may be diverted from other business concerns. These rules and regulations can also make it more difficult for us to attract and retain qualified independent members of our board of directors. Additionally, these rules and regulations make it more difficult and more expensive for us to obtain director and officer liability insurance. We may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. The increased costs of compliance with public company reporting requirements and our potential failure to satisfy these requirements could have a material adverse effect on our operations, business, financial condition or results of operations.

We have identified material weaknesses in our internal control over financial reporting, resulting from control deficiencies in our IT general controls and process level controls. Failure to achieve and maintain effective internal control over financial reporting could result in our failure to accurately or timely report our financial condition or results of operations, which could have a material adverse effect on our business and stock price.

We are required to comply with the SEC rules implementing Sections 302 and 404 of the Sarbanes-Oxley Act, which require management to certify financial and other information in our quarterly and annual reports and provide an annual management report on the effectiveness of our controls over financial reporting. Although we are required to disclose changes made in our internal controls and procedures on a quarterly basis, we will not be required to make our first annual assessment of our internal controls over financial reporting pursuant to Section 404 until our Annual Report on Form 10-K for the fiscal year ending December 31, 2022. This assessment will need to include disclosure of any material weaknesses identified by our management in our internal control over financial reporting, as well as a statement that our independent registered public accounting firm has issued an opinion on the effectiveness of our internal control over financial reporting, provided that our independent registered public accounting firm will not be required to attest to the effectiveness of our internal control over financial reporting until our first annual report required to be filed with the SEC, following the later of the date we are deemed to be an “accelerated filer” or a “large accelerated filer,” each as defined in the Exchange Act, or the date we are no longer an emerging growth company, as defined in the Jumpstart Our Business Startups Act (“JOBS”) Act.

34

As previously disclosed in the Registration Statement, we identified material weaknesses in our internal control over financial reporting relating to the following:

In connection with the audit of our Consolidated Financial Statements for the 2021 predecessor and successor periods, and as further described in the attached financial statements, we identified a further material weakness surrounding our revenue recognition process, specifically around terms of contracts, revenue cut-off, and recognition of injection molding revenue over time.

A “material weakness” is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our consolidated financial statements will not be prevented or detected on a timely basis.

Management is working to remediate the material weaknesses by hiring additional qualified accounting and financial reporting personnel, implementing an advanced Enterprise Resource Planning (“ERP”) system, improving contract terms and support for revenue recognition, and further evolving our accounting processes. We may not be able to fully remediate these material weaknesses until these steps have been completed and have been operating effectively for a sufficient period of time. We cannot assure you that the measures we have taken to date and plan to take will be sufficient to remediate the material weakness we identified or avoid the identification of additional material weaknesses in the future. If we are not able to maintain effective internal control over financial reporting, our financial statements and related disclosures may be inaccurate, which could have a material adverse effect on our business and our stock price.

The CORE Investors have substantial influence over our management and policies, and their interests may conflict with ours or yours in the future.

CORE Industrial Partners Fund I, L.P. and CORE Industrial Partners Fund I Parallel, L.P. (the “CORE Investors”) beneficially own approximately 63.1% of our Class A common stock and Class B common stock, which will generally vote together as a single class on matters submitted to a vote of our stockholders, including the election of directors. As a result, the CORE Investors have the ability to influence our business and affairs through their ability to control matters generally submitted to our stockholders for approval, including the election of directors, “negative control” rights through their ownership of our common stock combined with certain supermajority voting provisions of our certificate of incorporation (our “Charter”) and amended and restated bylaws (our “Bylaws”), and the provisions in the Investor Rights Agreement described below. If the other holders of our Class A common stock are dissatisfied with the performance of our board of directors, they have no ability to remove any of our directors, unless for cause and then only upon the affirmative vote of holders of 66-2/3% of our outstanding Class A common stock and Class B common stock, voting as a single class.

35

In addition, in connection with the Business Combination, we entered into the Investor Rights Agreement with the CORE Investors which provides for an initial ten-person board of directors, consisting of nine individuals designated by the CORE Investors, and one independent director mutually agreed by the CORE Investors and Altimar Sponsor II, LLC (the “Sponsor”). The CORE Investors have certain continued nomination rights for a number of directors ranging from the majority of the board of directors to one director, while they beneficially own shares of common stock in excess of certain ownership percentage of the amount owned by the CORE Investors at the closing of the Business Combination (“Closing”), as determined in accordance with the Investor Rights Agreement. In addition, for so long as the CORE Investors beneficially own shares of common stock representing at least 5% of the amount owned by the CORE Investors at Closing, the CORE Investors will have the right to designate a person to attend meetings of our board (including any meetings of any committees thereof) in a non-voting observer capacity. See “Certain Relationships and Related Party Transactions, and Director Independence—Investor Rights Agreement” for more details with respect to the Investor Rights Agreement.

The CORE Investors and their affiliates engage and will continue to engage in a broad spectrum of activities, including investments in the manufacturing and industrial industries generally, and engage and may continue to engage in the same or similar activities or related lines of business as those in which we are engaged or may engage in, directly or indirectly. In the ordinary course of their business activities, the CORE Investors and their affiliates may engage in activities in which their interests conflict with our interests or those of our other shareholders, such as investing in or advising businesses that directly or indirectly compete with certain portions of our business or are suppliers or partners of ours. Our Charter provides that none of the CORE Investors, any of their affiliates or any director who is not employed by us (including any non-employee director who serves as one of our officers in both his director and officer capacities) or its affiliates will have any duty to refrain from engaging, directly or indirectly, in the same business activities or similar business activities or lines of business in which we operate. The CORE Investors and their affiliates also may pursue acquisition opportunities that may be complementary to our business and, as a result, those acquisition opportunities may not be available to us. In addition, the CORE Investors and their affiliates may have an interest in pursuing acquisitions, divestitures and other transactions that, in their judgment, could enhance their investment, even though such transactions might involve risks to you.

Since we are a “controlled company” for purposes of the corporate governance requirements of the NYSE, our stockholders will not have, and may never have, the protections that these corporate governance requirements are intended to provide.

Since we are a “controlled company” for purposes of the corporate governance requirements of the NYSE, we are not required to comply with the provisions requiring that a majority of our directors be independent, the compensation of our executives be determined by independent directors or nominees for election to our board of directors be selected by independent directors. If we choose to take advantage of any or all of these exemptions, our stockholders may not have the protections that these rules are intended to provide.

Under SEC Rules, we are an “emerging growth company” and a “smaller reporting company” and the reduced SEC disclosure requirements applicable to emerging growth companies and smaller reporting companies may make our common stock less attractive to investors.

As a newly public company, we are an “emerging growth company,” as defined in the JOBS Act. As an emerging growth company we may follow reduced disclosure requirements and do not have to make all of the disclosures that public companies that are not emerging growth companies do. We will remain an emerging growth company until the earlier of (a) the last day of the fiscal year in which we have total annual gross revenues of $1.0 billion or more (as adjusted for inflation); (b) the last day of the fiscal year following the fifth anniversary of the date of the completion of the initial public offering of Fathom; (c) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years; or (d) the date on which we are deemed to be a large accelerated filer under the rules of the SEC, which means the market value of our

36

common stock that is held by non-affiliates exceeds $700 million as of the prior June 30. For so long as we remain an emerging growth company, we are permitted and intend to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not emerging growth companies. These exemptions include:

In addition, the JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to use the extended transition period for complying with new or revised accounting standards; and as a result of this election, our financial statements may not be comparable to companies that comply with public company effective dates.

We may choose to take advantage of some, but not all, of the available exemptions for emerging growth companies. We cannot predict whether investors will find our common stock less attractive if we rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our share price may be more volatile.

In order to satisfy our obligations as a public company, we will need to hire qualified accounting and financial personnel with appropriate public company experience.

As a newly public company, we will need to establish and maintain effective disclosure and financial controls and make changes in our corporate governance practices. We may need to hire additional accounting and financial personnel with appropriate public company experience and technical accounting knowledge, and it may be difficult to recruit and retain such personnel. Even if we are able to hire appropriate personnel, our existing operating expenses and operations will be impacted by the direct costs of their employment and the indirect consequences related to the diversion of management resources from research and development efforts.

The Company may be subject to securities litigation, which is expensive and could divert management attention.

Following the Business Combination, the per share price of the Class A common stock may be volatile and, in the past, companies that have experienced volatility in the market price of their stock have been subject to securities litigation, including class action litigation. Litigation of this type could result in substantial costs and diversion of management’s attention and resources, which could have a material adverse effect on our business, financial condition, and results of operations. Any adverse determination in litigation could also subject the Company to significant liabilities.

37

Because we became a publicly traded company by means other than a traditional underwritten initial public offering, the Company’s stockholders may face additional risks and uncertainties.

Because we became a publicly traded company by means of consummating the Business Combination rather than by means of a traditional underwritten initial public offering, there is no independent third-party underwriter selling the shares of the Company’s Class A common stock, and, accordingly, the Company’s stockholders will not have the benefit of an independent review and investigation of the type normally performed by an unaffiliated, independent underwriter in a public securities offering. Due diligence reviews typically include an independent investigation of the background of the company, any advisors and their respective affiliates, review of the offering documents and independent analysis of the plan of business and any underlying financial assumptions. Although Altimar II performed a due diligence review and investigation of Fathom OpCo in connection with the Business Combination, the lack of an independent due diligence review and investigation increases the risk of investment in the Company because Altimar II’s due diligence review and investigation may not have uncovered facts that would be important to a potential investor.

In addition, because the Company did not become a publicly traded company by means of a traditional underwritten initial public offering, security or industry analysts may not provide, or be less likely to provide, coverage of the Company. Investment banks may also be less likely to agree to underwrite secondary offerings on behalf of the Company than they might otherwise be if the Company became a publicly traded company by means of a traditional underwritten initial public offering because they may be less familiar with the Company as a result of more limited coverage by analysts and the media. The failure to receive research coverage or support in the market for the Company’s Class A common stock could have an adverse effect on the Company’s ability to develop a liquid market for the Company’s Class A common stock.

Risks Related to our Structure and Governance

Delaware law, our Charter and our Bylaws contain certain provisions, including anti-takeover provisions, that limit the ability of stockholders to take certain actions and could delay or discourage takeover attempts that stockholders may consider favorable.

Our Charter and the Delaware General Corporation Law (“DGCL”) contain provisions that could have the effect of rendering more difficult, delaying, or preventing an acquisition deemed undesirable by the Fathom board of directors and therefore depress the trading price of Fathom’s Class A common stock. These provisions could also make it difficult for stockholders to take certain actions, including electing directors who are not nominated by the current members of the our board of directors or taking other corporate actions, including effecting changes in management. Among other things, our Charter and Bylaws include provisions regarding:

38

These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in our board or management.

In addition, as a Delaware corporation, Fathom generally is subject to provisions of Delaware law, including the DGCL, although Fathom has elected not to be governed by Section 203 of the DGCL.

Any provision of our Charter, our Bylaws or Delaware law that has the effect of delaying or preventing a change in control could limit the opportunity for stockholders to receive a premium for their shares of Fathom’s capital stock and could also affect the price that some investors are willing to pay for Fathom’s common stock.

In addition, the provisions of the Investor Rights Agreement, as described herein, provide the stockholders party thereto with certain board representation and other consent rights that could also have the effect of delaying or preventing a change in control.

Our Charter designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by Fathom’s stockholders, which could limit Fathom’s stockholders’ ability to obtain a favorable judicial forum for disputes with Fathom or its directors, officers or other employees.

The Charter provides that, unless Fathom consents in writing to the selection of an alternative forum, (a) any derivative action or proceeding brought on behalf of Fathom, (b) any action asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, other employee, agent or stockholder of Fathom to Fathom or Fathom’s stockholders, or any claim for aiding and abetting such alleged breach, (c) any action asserting a claim against Fathom or any current or former director, officer, other employee, agent or stockholder of Fathom (i) arising pursuant to any provision of the DGCL, our Charter (as it may be amended or restated) or our Bylaws or (ii) as to which the DGCL confers jurisdiction on the Delaware Court of Chancery or (d) any action asserting a claim against Fathom or any current or former director, officer, other employee, agent or stockholder of Fathom governed by the internal affairs doctrine of the law of the State of Delaware shall, as to any action in the foregoing clauses (a) through (b), to the fullest extent permitted by law, be solely and exclusively brought in the Delaware Court of Chancery; provided, however, that the foregoing shall not apply to any claim arising under federal securities laws, including the Securities Act as to which the federal district courts of the United States of America shall, to the fullest extent permitted by law, be the sole and exclusive forum. Notwithstanding the foregoing, the provisions of Article XI of our Charter will not apply to suits brought to enforce any liability or duty created by the Exchange Act, or any other claim for which the federal district courts of the United States of America shall be the sole and exclusive forum. Further, Section 22 of the Securities Act of 1933 (the “Securities Act”) creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by that act or the rules and regulations thereunder. Accordingly, there is uncertainty as to whether a court would enforce this forum selection provision as written as to claims arising under the Securities Act.

This choice-of-forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with Fathom or its directors, officers, stockholders, agents or other employees, which

39

may discourage such lawsuits. Alternatively, if a court were to find this provision of our Charter inapplicable or unenforceable with respect to one or more of the specified types of actions or proceedings, Fathom may incur additional costs associated with resolving such matters in other jurisdictions, which could materially and adversely affect Fathom’s business, financial condition and results of operations and result in a diversion of the time and resources of Fathom’s management and board of directors.

Our Charter does not limit the ability of the CORE Investors to compete with us.

The CORE Investors and their affiliates engage in a broad spectrum of activities, including investments in the financial services and technology industries. In the ordinary course of their business activities, the CORE Investors and their affiliates may engage in activities where their interests conflict with Fathom’s interests or those of its stockholders. Our Charter provides that none of the CORE Investors, any of their affiliates or any director who is not employed by Fathom (including any non-employee director who serves as one of its officers in both his director and officer capacities) or its affiliates will have any duty to refrain from engaging, directly or indirectly, in the same business activities or similar business activities or lines of business in which Fathom operates. The CORE Investors and their affiliates also may pursue, in their capacities other than as directors of Fathom, acquisition opportunities that may be complementary to Fathom’s business, and, as a result, those acquisition opportunities may not be available to Fathom. In addition, the CORE Investors may have an interest in pursuing acquisitions, divestitures and other transactions that, in their judgment, could enhance their investment, even though such transactions might involve risks to you.

We are a holding company and our only material asset is our interest in Fathom OpCo, and we are accordingly dependent upon distributions made by Fathom OpCo to pay taxes, and other expenses, including payments under the Tax Receivable Agreement.

We are a holding company with no material assets other than our Class A common units in Fathom OpCo (“New Fathom Units”). As a result, Fathom has no independent means of generating revenue or cash flow. Our ability to pay taxes, and other expenses, including payments under the TRA, described in Note 21—Income Taxes within our consolidated financial statements, will depend on the financial results and cash flows of Fathom OpCo and its subsidiaries and the distributions we receive from Fathom OpCo. Deterioration in the financial condition, earnings or cash flow of Fathom OpCo and its subsidiaries for any reason could limit or impair Fathom OpCo’s ability to pay such distributions. Additionally, to the extent that we need funds and Fathom OpCo and/or its subsidiaries are restricted from making such distributions under applicable law or regulation or under the terms of any financing arrangements, or Fathom OpCo and/or its subsidiaries are otherwise unable to provide such funds, it could materially adversely affect Fathom’s liquidity and financial condition.

Subject to the discussion herein, Fathom OpCo will continue to be treated as a partnership for U.S. federal income tax purposes and, as such, generally will not be subject to any entity-level U.S. federal income tax. Instead, taxable income will be allocated to holders of New Fathom Units. Accordingly, we will be required to pay income taxes on our allocable share of any net taxable income of Fathom OpCo. Under the terms of the Second Amended and Restated Limited Liability Company Agreement of Fathom Holdco, LLC dated as of December 23, 2021 (the “Fathom Operating Agreement”), Fathom OpCo is obligated to make tax distributions to holders of the New Fathom Units (including us) calculated at certain assumed tax rates. In addition to tax expenses, we will also incur expenses related to our operations, including our payment obligations under the TRA, which could be significant, and some of which will be reimbursed by Fathom OpCo (excluding payment obligations under the TRA). We intend to cause Fathom OpCo to make ordinary distributions and tax distributions to holders of New Fathom Units on a pro rata basis in amounts sufficient to cover all applicable taxes, relevant operating expenses, payments by us under the TRA and dividends, if any, declared by us. However, as discussed above, Fathom OpCo’s ability to make such distributions may be subject to various limitations and restrictions including, but not limited to, retention of amounts necessary to satisfy the obligations of Fathom OpCo and its subsidiaries and restrictions on distributions that would violate any applicable restrictions contained in Fathom OpCo’s or its subsidiaries’ debt agreements, or any applicable law, or that

40

would have the effect of rendering Fathom OpCo or a subsidiary insolvent. To the extent that Fathom is unable to make payments under the TRA for any reason, such payments will be deferred and will accrue interest until paid; provided, however, that nonpayment for a specified period may constitute a breach of a material obligation under the Tax Receivable Agreement and therefore accelerate payments under the TRA, which could be substantial.

Additionally, although Fathom OpCo and its subsidiaries generally will not be subject to any entity-level U.S. federal income tax, they may be liable for audit adjustments to prior year tax returns, absent an election to the contrary. In the event Fathom OpCo’s calculations of taxable income are incorrect, Fathom OpCo, its subsidiaries and/or their respective owners, including us, in later years may be subject to material liabilities as a result of such audits.

If Fathom OpCo were treated as a corporation for U.S. federal income tax or state tax purposes, then the amount available for distribution by Fathom OpCo could be substantially reduced and the value of our common stock could be adversely affected.

An entity that would otherwise be classified as a partnership for U.S. federal income tax purposes (such as Fathom OpCo) may nonetheless be treated as, and taxable as, a corporation if it is a “publicly traded partnership” unless an exception to such treatment applies. An entity that would otherwise be classified as a partnership for U.S. federal income tax purposes will be treated as a “publicly traded partnership” if interests in such entity are traded on an established securities market or interests in such entity are readily tradable on a secondary market or the substantial equivalent thereof. If Fathom OpCo were determined to be treated as a “publicly traded partnership” (and taxable as a corporation) for U.S. federal income tax purposes, Fathom OpCo would be taxable on its income at the U.S. federal income tax rates applicable to corporations and distributions by Fathom OpCo to its partners (including Fathom) could be taxable as dividends to such partners to the extent of the earnings and profits of Fathom OpCo. In addition, we would no longer have the benefit of increases in the tax basis of Fathom OpCo’s assets as a result of exchanges of New Fathom Units for shares of Fathom Class A common stock. Pursuant to the Fathom Operating Agreement, the Exchange TRA Parties (as defined in the TRA) may, from time to time, subject to the terms of the Fathom Operating Agreement, exchange their interests in Fathom OpCo and have such interests redeemed by Fathom OpCo for cash or Fathom stock. While such exchanges could be treated as trading in the interests of Fathom OpCo for purposes of testing “publicly traded partnership” status, the Fathom Operating Agreement requires us to impose restrictions on exchanges that we determine to be necessary or advisable so that Fathom OpCo is not treated as a “publicly traded partnership” for U.S. federal income tax purposes. Accordingly, while such position is not free from doubt, Fathom OpCo is expected to be operated such that it is not treated as a “publicly traded partnership” taxable as a corporation for U.S. federal income tax purposes and we intend to take the position that Fathom OpCo is not so treated as a result of exchanges of its interests pursuant to the Fathom Operating Agreement.

Pursuant to the Tax Receivable Agreement, we will be required to make payments to Blocker TRA Parties and Exchange TRA Parties (each as defined in the Tax Receivable Agreement) for certain tax benefits we may claim and those payments may be substantial.

The Exchange TRA Parties (as defined in the Tax Receivable Agreement) may in the future exchange their New Fathom Units, together with the cancellation of an equal number of shares of Class B common stock, for shares of Class A common stock, or cash pursuant to the Fathom Operating Agreement. Such transactions are expected to result in increases in our allocable share of the tax basis of the tangible and intangible assets of Fathom OpCo and its subsidiaries. These increases in tax basis may increase (for income tax purposes) depreciation and amortization deductions and therefore reduce the amount of income or franchise tax that Fathom would otherwise be required to pay in the future had such sales and exchanges never occurred. Additionally, in connection with the closing of the Business Combination Agreement, we acquired the Blockers from the Blocker TRA Parties (each as defined in the Tax Receivable Agreement). Certain tax assets and attributes of the Fathom Blockers may be available to reduce the amount of income or franchise tax that we would otherwise be required to pay in the future had we not acquired the Blockers.

41

In connection with the Business Combination, Fathom entered into the Tax Receivable Agreement, which generally provides for the payment by it of 85% of the net cash savings, if any, in U.S. federal, state and local, income and franchise tax (computed using certain assumptions to address the impact of state and local taxes) that it actually realizes (or in certain cases is deemed to realize) as a result of tax basis in certain assets and other tax attributes of the Blockers and of Fathom at the time of the Business Combination (including as a result of any cash payments made to Fathom OpCo in exchange for New Fathom Units pursuant to the Business Combination), any increases in tax basis and other tax benefits related to the payment of cash consideration pursuant to the Business Combination Agreement and any increases in tax basis and other tax benefits resulting from any exchange of New Fathom Units for shares of Class A common stock or cash in the future and tax benefits related to entering into and making payments under the Tax Receivable Agreement. We will retain the benefit of the remaining 15% of such tax savings.

Payments under the TRA are our obligation not Fathom OpCo’s. The actual increase in our allocable share of Fathom OpCo’s tax basis in its assets, as well as estimating the amount and timing of any payments due to the TRA Parties based on future exchanges under the TRA, is by its nature, imprecise. For purposes of the TRA, savings in tax generally are calculated by comparing Fathom’s actual tax liability (determined by using the actual applicable U.S. federal income tax rate and assumed combined state and local income tax rate) to the amount that Fathom would have been required to pay had it not been able to utilize any of the tax benefits subject to the TRA. The amounts payable, as well as the timing of any payments under the TRA will vary depending upon a number of factors, including the timing of exchanges, the market price of the Class A common stock at the time of the exchange, the extent to which such exchanges are taxable, the depreciation and amortization periods that will apply to any increases in tax basis, the U.S. federal income tax rate then applicable, and the amount and timing of the recognition of Fathom’s income. While many of the factors that will determine the amount of payments that we will make under the TRA are outside of its control, we expect that the payments it will make under the TRA will be substantial. At this time, we are not able to provide a meaningful range of the total amount of payments to be made under the TRA resulting from future exchanges of New Fathom Units for shares of Class A common stock with any specificity or reliability for the reasons discussed above. However, we estimate that the total amount of future tax benefit payments anticipated to be made in the future as a result of the tax basis of Fathom at the time of the Business Combination will be $14.4 million. The amount of these payments is based upon the assumptions that (i) there are no changes in future income tax rates or tax laws, (ii) Fathom is able to fully utilize tax attributes arising in connection with the Business Combination in future tax periods, and (iii) there is no acceleration of amounts due under the TRA on account of early termination.

Any payments made by us under the Tax Receivable Agreement will generally reduce the amount of overall cash flow that might have otherwise been available to us. To the extent that we are unable to make timely payments under the Tax Receivable Agreement for any reason, the unpaid amounts will be deferred and will accrue interest until paid; however, nonpayment for a specified period may constitute a breach of a material obligation under the Tax Receivable Agreement and therefore accelerate payments due under the Tax Receivable Agreement, as further described below. Furthermore, our future obligation to make payments under the Tax Receivable Agreement could make us a less attractive target for an acquisition, particularly in the case of an acquirer that cannot use some or all of the tax benefits that may be realized or deemed realized under the Tax Receivable Agreement. See the section entitled “The Business Combination Agreement—Related Agreements— Tax Receivable Agreement.”

In certain cases, payments under the Tax Receivable Agreement may exceed the actual tax benefits Fathom realizes or be accelerated.

Payments under the Tax Receivable Agreement will be based on the tax reporting positions that Fathom determines under the procedures and assumptions set forth in the Tax Receivable Agreement, and the U.S. Internal Revenue Service (“IRS”) or another taxing authority may challenge all or any part of the tax basis increases, as well as other tax positions that Fathom takes, and a court may sustain such a challenge. In the event that any tax benefits initially claimed by Fathom are disallowed, the Exchange TRA Parties and the Blocker TRA

42

Parties (each as defined in the Tax Receivable Agreement) will not be required to reimburse Fathom for any excess payments that may previously have been made under the Tax Receivable Agreement, for example, due to adjustments resulting from examinations by taxing authorities. Rather, excess payments made to such holders will be netted against any future cash payments otherwise required to be made by Fathom under the Tax Receivable Agreement, if any, after the determination of such excess. However, a challenge to any tax benefits initially claimed by Fathom may not arise for a number of years following the initial time of such payment or, even if challenged early, such excess cash payment may be greater than the amount of future cash payments that Fathom might otherwise be required to make under the terms of the Tax Receivable Agreement and, as a result, there might not be future cash payments against which to net. Actual tax benefits realized by Fathom may differ from tax benefits calculated under the Tax Receivable Agreement as a result of the use of certain assumptions in the Tax Receivable Agreement, including the use of an assumed weighted-average state and local income tax rate to calculate tax benefits. As a result, in certain circumstances Fathom could make payments under the Tax Receivable Agreement in excess of Fathom’s actual income or franchise tax savings, which could materially impair Fathom’s financial condition.

Moreover, the Tax Receivable Agreement provides that, in certain events, including a change of control, breach of a material obligation under the Tax Receivable Agreement, or Fathom’s exercise of early termination rights, Fathom’s obligations under the Tax Receivable Agreement will accelerate and Fathom will be required to make a lump-sum cash payment to the Exchange TRA Parties and the Blocker TRA Parties and other applicable parties to the Tax Receivable Agreement equal to the present value of all forecasted future payments that would have otherwise been made under the Tax Receivable Agreement, which lump-sum payment would be based on certain assumptions, including those relating to Fathom’s future taxable income. The lump-sum payment could be substantial and could exceed the actual tax benefits that Fathom realizes subsequent to such payment because such payment would be calculated assuming, among other things, that Fathom would have certain tax benefits available to it and that Fathom would be able to use the potential tax benefits in future years. Assuming no material changes in the relevant tax law, we expect that if we experienced a change of control or the Tax Receivable Agreement had been terminated immediately after the Business Combination, the estimated lump-sum payment would be approximately $293.2 million (calculated using a discount rate equal to a per annum rate of LIBOR plus 100 basis points, applied against an undiscounted liability of approximately $258.9 million).

There may be a material negative effect on Fathom’s liquidity if the payments required to be made by Fathom under the Tax Receivable Agreement exceed the actual income or franchise tax savings that Fathom realizes. Furthermore, Fathom’s obligations to make payments under the Tax Receivable Agreement could also have the effect of delaying, deferring or preventing certain mergers, asset sales, other forms of business combinations or other changes of control.

Fathom OpCo may directly or indirectly make distributions of cash to us substantially in excess of the amounts we use to make distributions to our stockholders and pay our expenses (including our taxes and payments by us under the Tax Receivable Agreement). To the extent we do not distribute such excess cash as dividends to our shareholders, the direct or indirect holders of New Fathom Units would benefit from any value attributable to such cash as a result of their ownership of our stock upon an exchange of their New Fathom Units.

We are entitled to receive a pro rata portion of any distributions made by Fathom OpCo. Any cash received from such distributions will first be used to satisfy any tax liability and then to make any payments required to be made by Fathom under the TRA. Subject to having available cash and subject to limitations imposed by applicable law and contractual restrictions, the Fathom Operating Agreement requires Fathom OpCo to make certain distributions to holders of New Fathom Units (including Fathom) pro rata to facilitate the payment of taxes with respect to the income of Fathom OpCo that is allocated to them. To the extent that the tax distributions we directly or indirectly receive exceed the amounts we actually require to pay taxes, TRA payments and other expenses (which is likely to be the case given that the assumed tax rate for such distributions will generally

43

exceed our effective tax rate), we will not be required to distribute such excess cash. Our board of directors may, in its sole discretion, choose to use such excess cash for certain purposes, including to make distributions to the holders of our stock. Unless and until our board of directors chooses, in its sole discretion, to declare a distribution, we will have no obligation to distribute such cash (or other available cash other than any declared dividend) to our stockholders.

No adjustments to the exchange ratio of New Fathom Units for shares of our common stock will be made as a result of either (i) any cash distribution by us or (ii) any cash that we retain and do not distribute to our stockholders. To the extent we do not distribute such cash as dividends and instead, for example, hold such cash balances or use such cash for certain other purposes, this may result in shares of our stock increasing in value relative to the New Fathom Units. The holders of New Fathom Units may benefit from any value attributable to such cash balances if they acquire shares of our stock in an exchange of New Fathom Units.

We may amend the terms of the Warrants in a manner that may be adverse to holders of Public Warrants with the approval by the holders of at least 50% of the then outstanding Public Warrants. As a result, the exercise price of the Warrants could be increased, the exercise period could be shortened and the number of Class A common stock purchasable upon exercise of a Warrant could be decreased, all without approval of each Warrant affected.

Our Warrants were issued in registered form under a Warrant Agreement between Continental Stock Transfer and Trust Company, as Warrant Agent, and us. The Warrants collectively consist of (i) 9,900,000 warrants to purchase one of Altimar II’s Class A ordinary shares acquired by the Sponsor in a private placement simultaneously with the closing of the Altimar II IPO (the “Private Placement Warrants”) and (ii) 8,625,000 warrants issued in the Altimar II IPO, entitling the holder thereof to purchase one of Altimar II’s Class A ordinary shares (the “Public Warrants” and, collectively with the Private Placement Warrants, the “Warrants”). Upon closing of the Business Combination, the shares issuable upon exercise of the Private Placement Warrants and the Public Warrants became shares of Fathom’s Class A common stock. The Warrant Agreement provides that the terms of the Warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval by the holders of at least 50% of the then outstanding Public Warrants to make any change that adversely affects the interests of the registered holders of Public Warrants. Accordingly, we may amend the terms of the Public Warrants in a manner adverse to a holder if holders of at least 50% of the then outstanding Public Warrants approve of such amendment. Although our ability to amend the terms of the Public Warrants with the consent of at least 50% of the then outstanding Public Warrants is unlimited, examples of such amendments could be amendments to, among other things, increase the exercise price of the Warrants, convert the Warrants into cash, shorten the exercise period or decrease the number of shares of Class A common stock, as applicable, purchasable upon exercise of a Warrant.

We may redeem unexpired Warrants prior to their exercise at a time that is disadvantageous to holders of Warrants, thereby making such Warrants worthless.

We may redeem unexpired Warrants prior to their exercise at a time that is disadvantageous to holders of Warrants, thereby making such Warrants worthless.

We have the ability to redeem outstanding Warrants at any time after they become exercisable and prior to their expiration, at a price of $0.01 per Warrant, provided that the last sale price of our Class A common stock equals or exceeds $18.00 per share (as adjusted for share splits, share capitalizations, reorganizations, recapitalizations and the like) on each of 20 trading days within a 30 trading-day period ending on the third trading day prior to the date on which notice of such redemption is given. We will not redeem the Warrants unless an effective registration statement under the Securities Act covering the Class A common stock, issuable upon exercise of the Warrants is effective and a current prospectus relating to the Class A common stock, is available throughout the 30-day redemption period, except if the Warrants may be exercised on a cashless basis and such cashless exercise is exempt from registration under the Securities Act. If and when the Warrants

44

become redeemable by us, we may exercise our redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws. Redemption of the outstanding Warrants could force holders thereof to (i) exercise Warrants and pay the exercise price therefor at a time when it may be disadvantageous for such holder to do so, (ii) sell Warrants at the then-current market price when such holder might otherwise wish to hold Warrants or (iii) accept the nominal redemption price which, at the time the outstanding Warrants are called for redemption, is likely to be substantially less than the market value of such Warrants. None of the Private Placement Warrants will be redeemable by us so long as they are held by their initial purchasers or their permitted transferees.

In addition, we may redeem Warrants after they become exercisable for a number of shares of Class A common stock determined based on the redemption date and the fair market value of our Class A common stock. Any such redemption may have similar consequences to a cash redemption described above. In addition, such redemption may occur at a time when the Warrants are “out-of-the-money,” in which case holders thereof would lose any potential embedded value from a subsequent increase in the value of the Class A common stock had such Warrants remained outstanding.

We will receive up to an aggregate of approximately $227.7 million from the exercise of the Warrants, assuming the exercise in full of all 18,525,000 Warrants for cash. We will have broad discretion over the use of proceeds from the exercise of the Warrants. We expect to use the net proceeds from the exercise of the Warrants, if any, for general corporate purposes. There is no assurance that the holders of the Warrants will elect to exercise any or all of such Warrants. To the extent that the Warrants are exercised on a “cashless basis,” the amount of cash we would receive from the exercise of the Warrants will decrease.
