This presentation ("Presentation") contemplates a business combination (the "Business Combination") between one ("one") and Markforged, Inc. ("Markforged" or the "Company"). The information contained herein does not purport to be all-inclusive and neither of one, Markforged, nor any of their respective affiliates nor any of its or their control persons, officers, directors, employees or representatives makes any representation or warranty, express or implied, as to the accuracy, completeness or reliability of the information contained in this Presentation. You should consult your own counsel and tax and financial advisors as to legal and related matters concerning the matters described herein, and, by accepting this Presentation, you confirm that you are not relying upon the information contained herein to make any decision. 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. In some cases, you can identify forward-looking statements by terminology such as "may", "should", "expect", "intend", "will", "estimate", "anticipate", "believe", "predict", "potential" or "continue", or the negatives of these terms or variations of them or similar terminology. 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 (i) 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 shareholders of one is not obtained; (ii) the ability to maintain the listing of the combined company's securities on the NYSE; (iii) the inability to complete the PIPE; (iv) 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; (v) the risk that any of the conditions to closing are not satisfied in the anticipated manner or on the anticipated timeline; (vi) the failure to realize the anticipated benefits of the proposed business combination; (vii) risks relating to the uncertainty of the projected financial information with respect to Markforged and costs related to the proposed business combination; (viii) the outcome of any legal proceedings that may be instituted against the parties following the announcement of the proposed business combination; (ix) the amount of redemption requests made by one's public shareholders; (x) the effects of the COVID-19 pandemic and general economic conditions; (xi) and other assumptions, risks, uncertainties and factors set forth in the sections entitled "Projected Financial Information," "Risk Factors" and "Cautionary Note Regarding Forward-Looking Statements" in one's Amendment No. 1 to Registration Statement on Form S-4 relating to the Business Combination, dated May 14, 2021 (the "Registration Statement"), 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. Nothing in this Presentation should be regarded as a representation by any person that the forward-looking statements set forth herein will be achieved or that any of the contemplated results of such forward-looking statements will be achieved. You should not place undue reliance on forward-looking statements in this Presentation, which speak only as of the date they are made and are qualified in their entirety by reference to the cautionary statements herein. Neither one nor the Company undertakes any duty to update these forward-looking statements. Additional Information.

A list of the names of one and Markforged's directors and executive officers, a description of their interests in each of one and Markforged and additional information regarding the interests of the participants in the solicitation of proxies from one's shareholders is contained in the Registration Statement which was filed with the SEC and is available free of charge at the SEC's web site at www.sec.gov, or by directing a request to one, 16 Funston Avenue, Suite A, The Presidio of San Francisco, San Francisco, CA 94129. No Offer or Solicitation. This communication is for informational purposes only and does not constitute, or form a part of, an offer to sell or the solicitation of an offer to sell or an offer to buy or the solicitation of an offer to buy any securities, and there shall be no sale of securities, in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.

Certain information contained in this Presentation relates to or is based on publications, surveys and the Company's own internal estimates and research. In addition, all of the market data included in this Presentation involves a number of assumptions and limitations, and there can be no guarantee as to the accuracy or reliability of such assumptions. Please see the Registration Statement for further information. 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 Adjusted 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#4Introduction#5Presenters Today Markforged LO 5 Shai Terem President & CEO stratasys Morgan Stanley Kornit 20 Digital banding matters David Benhaim Co-Founder & CTO QPalantiri KYRUUS Mark Schwartz Chief Finance Officer trax LAUNCHPAD DIGITAL HEALTH fabrinet ONE Kevin Hartz one Co-Founder & CEO eventbrite FOUNDERS FUND xoom a PayPal Se#6one's Track Record of Early Investments in Transformational Businesses 6 2010 2011 Square Palantir / airbnb 2009 2012 Uber trulia 2005 2014 Opendoor/ reddit Note: $ in billions.
