No such offering of securities shall be made except by means of a prospectus meeting the requirements of section 10 of the Securities Act of 1933, as amended, or an exemption therefrom. You should not construe the contents of this Presentation as legal, tax, accounting or investment advice or a recommendation.

The recipient acknowledges that it is (a) aware that the United States securities laws prohibit any person who has material, non - public information concerning a company from purchasing or selling securities of such company or from communicating such information to any other person under circumstances in which it is reasonably foreseeable that such person is likely to purchase or sell such securities, and (b) familiar with the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the "Exchange Act"), and that the recipient will neither use, nor cause any third party to use, this Presentation or any information contained herein in contravention of the Exchange Act, including, without limitation, Rule 10b - 5 thereunder. This Presentation and information contained herein constitutes conﬁdential information and is provided to you on the condition that you agree that you will hold it in strict conﬁdence and not reproduce, disclose, forward or distribute it in whole or in part without the prior written consent of the Company and is intended for the recipient hereof only. Use of Projections This Presentation contains ﬁnancial forecasts for the Company with respect to certain ﬁnancial results for the Company's ﬁscal years 2021 through 2025. The Company's independent auditors have not audited, studied, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this Presentation, and accordingly, they did not express an opinion or provide any other form of assurance with respect thereto for the purpose of this Presentation. These projections are forward - looking statements and should not be relied upon as being necessarily indicative of future results. In this Presentation, certain of the above - mentioned projected information has been provided for purposes of providing comparisons with historical data. The assumptions and estimates underlying the prospective ﬁnancial information are inherently uncertain and are subject to a wide variety of signiﬁcant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective ﬁnancial information. Accordingly, there can be no assurance that the prospective results are indicative of the future performance of the Company or that actual results will not differ materially from those presented in the prospective ﬁnancial information. Inclusion of the prospective ﬁnancial information in this Presentation should not be regarded as a representation by any person that the results contained in the prospective ﬁnancial information will be achieved. F i nanc i al Inf o r m a t i on; Non - GAAP Measures The ﬁnancial information and data contained in this Presentation is unaudited and does not conform to Regulation S - X. Such information and data may not be included in, may be adjusted in or may be presented differently in the registration statement to be ﬁled relating to the Business Combination and the proxy statement/prospectus contained therein. This Presentation also includes certain ﬁnancial measures not presented in accordance with generally accepted accounting principles (“GAAP”) including, but not limited to, EBITDA and certain ratios and other metrics derived therefrom. The Company deﬁnes EBITDA as operating income plus depreciation and amortization expenses. These non - GAAP ﬁnancial measures are not measures of ﬁnancial performance in accordance with GAAP and may exclude items that are signiﬁcant in understanding and assessing the Company’s ﬁnancial results. Therefore, these measures should not be considered in isolation or as an alternative to net income, cash ﬂows from operations or other measures of proﬁtability, liquidity or performance under GAAP. You should be aware that the Company’s presentation of these measures may not be comparable to similarly - titled measures used by other companies. The Company believes these non - GAAP measures of ﬁnancial results provide useful information to management and investors regarding certain ﬁnancial and business trends relating to the Company’s ﬁnancial condition and results of operations. The Company believes that the use of these non - GAAP ﬁnancial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends in and in comparing the Company’s ﬁnancial measures with other similar companies, many of which present similar non - GAAP ﬁnancial measures to investors. These non - GAAP ﬁnancial measures are subject to inherent limitations as they reﬂect the exercise of judgments by management about which expense and income are excluded or included in determining these non - GAAP ﬁnancial measures. This Presentation also includes certain projections of non - GAAP ﬁnancial measures. Due to the high variability and diﬃculty in making accurate forecasts and projections of some of the information excluded from these projected measures, together with some of the excluded information not being ascertainable or accessible, the Company is unable to quantify certain amounts that would be required to be included in the most directly comparable GAAP ﬁnancial measures without unreasonable effort. Consequently, no disclosure of estimated comparable GAAP measures is included and no reconciliation of the forward - looking non - GAAP ﬁnancial measures is included. Industry and Market Data In this Presentation, the Company relies on and refer to certain information and statistics obtained from third - party sources which they believe to be reliable. The Company has not independently veriﬁed the accuracy or completeness of any such third - party information. Trademarks This Presentation may contain trademarks, service marks, trade names and copyrights of other companies, which are the property of their respective owners. Solely for convenience, some of the trademarks, service marks, trade names and copyrights referred to in this Presentation may be listed without the TM, SM © or ® symbols, but the Company will assert, to the fullest extent under applicable law, the rights of the applicable owners, if any, to these trademarks, service marks, trade names and copyrights. 2 Disclaimer

Forward Looking Statements This document contains certain forward - looking statements within the meaning of the federal securities laws with respect to the proposed transaction between NewHold Investment Corp. (“NewHold”) and Evolv Technologies, Inc. (“Evolv”). These forward - looking statements generally are identified by the words “believe,” “project,” “expect,” “anticipate,” “estimate,” “intend,” “strategy,” “future,” “opportunity,” “plan,” “may,” “should,” “will,” “would,” “will be,” “will continue,” “will likely result,” and similar expressions. Forward - looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Many factors could cause actual future events to differ materially from the forward - looking statements in this document, including but not limited to: (i) the risk that the transaction may not be completed in a timely manner or at all, which may adversely affect the price of NewHold’s securities, (iii) the failure to satisfy the conditions to the consummation of the transaction, including the adoption of the Agreement and Plan of Merger, dated as of March 5, 2021 (the “Merger Agreement”), by and among NewHold, Evolv and NHIC Merger Sub Inc., a Delaware corporation and a direct wholly owned subsidiary of NewHold, by the stockholders of NewHold, the satisfaction of the minimum trust account amount following redemptions by NewHold’s public stockholders and the receipt of certain governmental and regulatory approvals, (iv) the lack of a third party valuation in determining whether or not to pursue the transaction, (v) the inability to complete the PIPE investment in connection with the transaction, (vi) the occurrence of any event, change or other circumstance that could give rise to the termination of the Merger Agreement, (vii) the effect of the announcement or pendency of the transaction on Evolv Aviation’s business relationships, operating results and business generally, (viii) risks that the proposed transaction disrupts current plans and operations of Evolv and potential difficulties in Evolv employee retention as a result of the transaction, (ix) the outcome of any legal proceedings that may be instituted against Evolv or against NewHold related to the Merger Agreement or the transaction, (x) the ability to maintain the listing of NewHold’s securities on a national securities exchange, (xi) the price of NewHold’s securities may be volatile due to a variety of factors, including changes in the competitive and highly regulated industries in which NewHold plans to operate or Evolv operates, variations in operating performance across competitors, changes in laws and regulations affecting NewHold’s or Evolv’s business and changes in the combined capital structure, (xii) the ability to implement business plans, forecasts, and other expectations after the completion of the transaction, and identify and realize additional opportunities, and (xiii) the risk of downturns and a changing regulatory landscape in Evolv’s highly competitive industry. The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties described in the “Risk Factors” section of NewHold’s registration on Form S - 1 (File No. 333 - 239822), the registration statement on Form S - 4 discussed above and other documents filed by NewHold from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward - looking statements. Forward - looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward - looking statements, and except as required by law NewHold and Evolv assume no obligation and do not intend to update or revise these forward - looking statements, whether as a result of new information, future events, or otherwise. Neither NewHold nor Evolv gives any assurance that either NewHold or Evolv or the combined company will achieve its expectations. Any financial projections in this communication are forward - looking statements that are based on assumptions that are inherently subject to significant uncertainties and contingencies, many of which are beyond NewHold’s and Evolv’s control . While all projections are necessarily speculative, NewHold and Evolv believe that the preparation of prospective financial information involves increasingly higher levels of uncertainty the further out the projection extends from the date of preparation . The assumptions and estimates underlying the projected results are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the projections . The inclusion of projections in this communication should not be regarded as an indication that NewHold and Evolv, or their representatives, considered or consider the projections to be a reliable prediction of future events . I m portant Infor m a t i on fo r In v es t ors and S t oc k ho l ders This document relates to a proposed transaction between NewHold and Evolv. This document does not constitute an offer to sell or exchange, or the solicitation of an offer to buy or exchange, any securities, nor shall there be any sale of securities in any jurisdiction in which such offer, sale or exchange would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. NewHold intends to file a registration statement on Form S - 4 with the SEC, which will include a document that serves as a prospectus and proxy statement of NewHold, referred to as a proxy statement/prospectus.

Risk Factors 40 Risks Related to Evolv Technology’s Business and Industry • We are a rapidly growing company with a history of losses. We have not been profitable historically and may not achieve or maintain profitability in the future. • Our operating results may fluctuate for a variety of reasons, including our failure to close significant customer sales. • We recognize substantially all of our revenue ratably over the term of our agreements with customers and, as a result, downturns or upturns in sales may not be immediately reflected in our operating results. • The touchless security screening market is new and evolving, and may not grow as expected or may develop more slowly or differently than we expect. If the market does not grow as we expect, or if we cannot expand our solutions to meet the demands of this market, our revenue may decline, fail to grow or fail to grow at an accelerated rate, and we may incur operating losses. • Forecasts of our market and market growth may prove to be inaccurate, and even if the markets in which we compete achieve the forecasted growth, there can be no assurance that our business will grow at similar rates, or at all. • If we are unable to acquire new customers, our future revenues and operating results will be harmed. Likewise, potential customer turnover in the future, or costs we incur to retain our existing customers, could materially and adversely affect our financial performance. • If we are unable to sell additional products to our customers and maintain and grow our customer retention rates, our future revenue and operating results will be harmed. • If our products fail or are perceived to fail to detect threats such as a firearm or other potential weapon or explosive device, or if our products contain undetected errors or defects, these failures or errors could result in the loss of life, which could harm our brand and reputation and have an adverse effect on our business and results of operations. • If we do not successfully anticipate market needs and enhance our existing products or develop new products that meet those needs on a timely basis, we may not be able to compete effectively and our ability to generate revenues will suffer. • Our business model is predicated, in part, on building a customer base that will generate a recurring stream of revenues through the sale of our subscription contracts. If that recurring stream of revenues does not develop as expected, or if our business model changes as the industry evolves, our operating results may be adversely affected. • Our sales cycles can be long and unpredictable, and our sales efforts require considerable time and expense. As a result, our sales and revenue are difficult to predict and may vary substantially from period to period, which may cause our results of operations to fluctuate significantly. • We rely on channel and OEM partners to generate a growing portion of our revenue, including in international markets. If we fail to maintain successful relationships with our channel and OEM partners, or if our partners fail to perform, our ability to market, sell and distribute our products will be limited, and our business, financial position and results of operations will be harmed. • A portion of our revenue is generated by sales to government entities, which are subject to a number of challenges and risks. • Fluctuating economic conditions make it difficult to predict revenue for a particular period, and a shortfall in revenue may harm our operating results. • Changes in or interpretations of financial accounting standards may cause an adverse impact to our reported results of operations. • Our brand, reputation and ability to attract, retain and serve our customers are dependent in part upon the reliable performance of our products and infrastructure. • If we are not able to maintain and enhance our brand or reputation as an industry leader, our business and operating results may be adversely affected. • If our customers are unable to implement our products successfully, or if we fail to effectively assist our customers in installing our products and provide effective ongoing support, customer perceptions of our products may be impaired or our reputation and brand may suffer. • We are dependent on the continued services and performance of our senior management and other key employees, as well as on our ability to successfully hire, train, manage and retain qualified personnel, especially those in sales and marketing and research and development.

Risk Factors (Cont.) 41 Risks Related to Evolv Technology’s Business and Industry (Cont.) • If we do not effectively expand, train and retain qualified sales and marketing personnel, we may be unable to acquire new customers or sell additional products to successfully pursue our growth strategy. • If we cannot maintain our company culture as we grow, we could lose the innovation, teamwork, passion and focus on execution that we believe contribute to our success and our business may be harmed. • We incorporate technology from third parties into our products, and our inability to obtain or maintain rights to the technology could harm our business. • We may acquire or invest in other companies or technologies in the future, which could divert management's attention, fail to meet our expectations, result in additional dilution to our stockholders, increase expenses, disrupt our operations or otherwise harm our operating results. • Our intellectual property rights are valuable and any inability to protect our proprietary technology and intellectual property rights could substantially harm our business and operating results. • Assertions by third parties of infringement or other violations by us of their intellectual property rights, whether or not correct, could result in significant costs and harm our business and operating results. • Confidentiality arrangements with employees and others may not adequately prevent disclosure of trade secrets and other proprietary information. • Our products and services may be affected from time to time by design and manufacturing defects that could adversely affect our business and result in harm to our reputation. • We rely on a limited number of suppliers, manufacturers, and logistics partners for our products. A loss of any of these partners could negatively affect our business. • Our third - party contract manufacturers' facilities, and our suppliers' and our customers' facilities, are vulnerable to disruption due to natural or other disasters, strikes and other events beyond our control. • Increases in component costs, long lead times, supply shortages, and supply changes could disrupt our supply chain and have an adverse effect on our business, financial condition, and operating results. • The continuation of worsening of the COVID - 19 coronavirus pandemic could have an adverse effect on our business, results of operations, and financial condition. • Downturns in general economic and market conditions and reductions in spending may reduce demand for our software, services, and products, which could harm our revenue, results of operations and cash flows. • If the general level of physical threats/attacks declines, or is perceived by our current or potential customers to have declined, our business could be harmed. • The markets in which we participate could become increasingly competitive. If we are unable to compete effectively with new entrants and other potential competitors, our sales and profitability could be adversely affected. • New entrants or other increased competition for our product offerings may cause us to lower the sale prices of our products and services, which may reduce our gross profits and adversely impact our financial results. • Because our products may collect and store user and related information, domestic and international privacy and cyber security concerns, and other laws and regulations, could result in additional costs and liabilities to us or inhibit sales of our products. • Failure to comply with applicable anti - corruption legislation and other governmental laws and regulations could result in fines, criminal penalties and materially adversely affect our business, financial condition and results of operations. • Comprehensive tax reform legislation could adversely affect our business and financial condition. • Our operating results may be harmed if we are required to collect sales and use or other related taxes for our products in jurisdictions where we have not historically done so. • We may not be able to utilize a significant portion of our net operating loss carryforwards and research and development tax credit carryforwards. • We may require additional capital to support business growth, and this capital might not be available on acceptable terms, if at all.
