Forward-Looking Statements. Certain statements in this Presentation may be considered forward-looking statements. Forward-looking statements generally relate to future events or one’s or the Company’s future financial or operating performance. For example, statements concerning the following include forward-looking statements: development plans for Markforged’s products; Markforged’s sales projections and financial estimates; the size and growth of the additive manufacturing market; the adoption of Markforged’s products in the manufacturing industry and other industries; and the potential effects of the Business Combination on the Company.

Such forward-looking statements are subject to risks, uncertainties, and other factors which could cause actual results to differ materially from those expressed or implied by such forward looking statements. These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by one and its management, and Markforged and its management, as the case may be, are inherently uncertain. New risks and uncertainties may emerge from time to time, and it is not possible to predict all risks and uncertainties. Factors that may cause actual results to differ materially from current expectations include, but are not limited to, various factors beyond management's control including the inability of the parties to successfully or timely consummate the proposed business combination, including the risk that any required regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the proposed business combination or that the approval of the stockholders of one is not obtained; (iii) the ability to maintain the listing of the combined company’s securities on NYSE; (iv) the inability to complete the PIPE; (v) the risk that the proposed business combination disrupts current plans and operations of Markforged as a result of the announcement and consummation of the transaction described herein; the risk that any of the conditions to closing are not satisfied in the anticipated manner or on the anticipated timeline; the failure to realize the anticipated benefits of the proposed business combination; risks relating to the uncertainty of the projected financial information with respect to Markforged and costs related to the proposed business combination; the outcome of any legal proceedings that may be instituted against the parties following the announcement of the proposed business combination; the amount of redemption requests made by one’s public stockholders; the effects of the COVID-19 pandemic, general economic conditions; and other risks, uncertainties and factors set forth in the section entitled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” in one’s final prospectus relating to its initial public offering, dated August 17, 2020, and other filings with the Securities and Exchange Commission (‘SEC”), as well as factors associated with companies, such as the Company, that are engaged in additive manufacturing.

Finally, while the Company believes its internal research is reliable, such research has not been verified by any independent source. This meeting and any information communicated at this meeting are strictly confidential and should not be discussed outside your organization. Use of Non-GAAP Financial Metrics. This presentation includes certain non-GAAP financial measures (including on a forward-looking basis) such as Adjusted EBITDA and Free Cash Flow. These non-GAAP measures are an addition to, and not a substitute for or superior to, measures of financial performance prepared in accordance with GAAP and should not be considered as an alternative to net income, operating income or any other performance measures derived in accordance with GAAP. Reconciliations of non-GAAP measures to their most directly comparable GAAP counterparts are included in the Appendix to this presentation. Markforged believes that these non-GAAP measures of financial results (including on a forward-looking basis) provide useful supplemental information to investors about Markforged. Markforged’s management uses forward-looking non-GAAP measures to evaluate Markforged’s projected financials and operating performance. However, there are a number of limitations related to the use of these non-GAAP measures and their nearest GAAP equivalents, including that they exclude significant expenses that are required by GAAP to be recorded in Markforged’s financial measures. In addition, other companies may calculate non-GAAP measures differently, or may use other measures to calculate their financial performance, and therefore, Markforged’s non-GAAP measures may not be directly comparable to similarly titled measures of other companies. Additionally, to the extent that forward-looking non-GAAP financial measures are provided, they are presented on a non-GAAP basis without reconciliations of such forward-looking non-GAAP measures due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliations. The reader shall not rely upon any statement, representation or warranty made by any other person, firm or corporation in making its investment or decision to invest in the Company. Neither of one, the Company, nor any of their respective affiliates nor any of its or their control persons, officers, directors, employees or representatives, shall be liable to the reader for any information set forth herein or any action taken or not taken by any reader, including any investment in shares of one or the Company. 3

Key Risk Factors

Key Risk Factors • Markforged is an early-stage company with a history of losses. The Company has not been profitable historically and may not achieve or maintain profitability in the future. • Markforged’s limited operating history and rapid growth makes evaluating its current business and future prospects difficult and may increase the risk of your investment. • The additive manufacturing industry in which Markforged operates is characterized by rapid technological change, which requires the Company to continue to develop new products and innovations to meet constantly evolving customer demands and which could adversely affect market adoption of its products. Moreover, the additive manufacturing industry is competitive and Markforged may face increasing competition in many aspects of its business, including from market incumbents and companies that are better capitalized than Markforged. • Markforged may experience significant delays in the design, production and launch of its additive manufacturing solutions, and it may be unable to successfully commercialize products on its planned timelines. Additionally, Markforged relies on a limited number of third-party logistics providers for shipment and distribution of its products to customers, and their failure to perform effectively would adversely affect its business. • Markforged depends on its network of value added resellers and its business could be adversely affected if they do not perform as expected. Markforged may not be able to sustain or develop new reseller relationships, and a reduction or delay in sales could hurt its business. • Markforged may be unable to consistently manufacture its products to the necessary specifications or in quantities necessary to meet demand at an acceptable cost or at an acceptable performance level. As manufacturing continues to scale, the Company will become exposed to accompanying risks and liabilities. • Markforged’s business model is predicated, in part, on expanding recurring revenues through the sale of its consumables and service contracts. If that recurring stream of revenues does not develop as expected, or if its business model changes as the industry evolves, its operating results may be adversely affected. • Markforged depend on a limited number of third-party contract manufacturers and its one production location for substantially all of its manufacturing needs. Similarly, it relies on a limited number of suppliers, some of which are single source suppliers of certain materials. If Markforged’s facility, or any of its third-party manufacturers or suppliers experience any delay, disruption or quality control problems in their operations, including due to the COVID-19 pandemic, the Company could lose market share and its brand may suffer. If any of Markforged’s third-party manufacturers and suppliers become unavailable or inadequate, the Company could have difficulty replacing them. Any interruption in production could adversely affect Markforged’s customer relationships, results of operations and financial condition. • Markforged relies on its information technology systems to manage numerous aspects of its business and operation of its printers and a disruption of these systems could adversely affect Markforged’s business. Breaches of laws and regulations concerning data protection and privacy could expose Markforged to significant fines and other penalties. Additionally, any unauthorized control or manipulation of Markforged’s products’ systems could result in loss of confidence in the Company and its products and harm its business. 46

Key Risk Factors (Cont’d) • If Markforged is unable to adequately protect or enforce its intellectual property rights or obtain and maintain patent protection for its technology and products or if the scope of the patent protection obtained is not sufficiently broad, such information may be used by others to compete against the Company, in particular in developing consumables that could be used with Markforged’s printing systems in place of its proprietary consumables. • Markforged’s existing and planned global operations subject the Company to a variety of risks and uncertainties that could adversely affect its business and operating results. Markforged’s business is subject to risks associated with selling additive manufacturing machines and other products, some of which may be subject to heightened export controls, in non-United States locations. • A significant portion of Markforged’s business depends on sales to the public sector, and the Company’s failure to receive and maintain government contracts on favorable terms or changes in the contracting or fiscal policies of the public sector could have a material adverse effect on the Company’s business. Some of Markforged’s products may be subject to governmental export regulations, which may limit the markets in which the Company can sell some of its products and the breach of which would expose the Company to liability. • Markforged is, and has been in the recent past, subject to litigation. The Company could be subject to intellectual property, personal injury, property damage, product liability, warranty and other claims involving allegedly defective products that it supplies. • Markforged could face liability if its additive manufacturing solutions are used by its customers to print dangerous objects, or if third parties produce or sell counterfeit or imitation versions of its consumables. • The global COVID-19 pandemic has significantly affected Markforged’s business and operations. Uncertainty regarding purchasing by customers, the measures taken by U.S. federal, state and local governments as well as foreign nations in response to the pandemic may continue to materially impact the Company’s business and future results of operation and financial condition. • Markforged’s management team has limited experience managing a public company. Further, failure to achieve and maintain effective internal controls over financial reporting in accordance with Section 404 of SOX could impair the Company’s ability to produce timely and accurate financial statements or comply with applicable regulations and have a material adverse effect on its business. Additionally, the Company will incur increased costs and become subject to additional regulations and requirements as a public company, which could impair its profitability, make it more difficult to run its business or divert management’s attention from its business. 47
