Subject Company: Evolv Technologies, Inc.

EMAIL SUBJECT: Evolv Plans to Go Public on NASDAQ!

***Please keep this memo confidential***

Dear Advisory Board,

Thank you for your continued support for our mission to make the world a safer place. Over the years, your counsel, suggestions, outreach and advocacy have helped us be the leading (and only) touchless security screening technology. Our ability to keep a wide range of venues, their staff, and visitors safe has been a major accomplishment. We’ve kept 50 million people safe, and screen over 1,000,000 people each week. All the hard work the organization has done over the past eight years has put us in a great position to significantly grow the business in the future.

We are excited to announce a remarkable milestone for Evolv as we plan to go public and list our stock on NASDAQ. This milestone will be accomplished through a merger with an already publicly traded special purpose acquisition company (SPAC), NewHold Investment Corp. (“NewHold”) (NASDAQ: NHIC).

We will continue to operate under the Evolv name and there will be no substantive changes to our team or how we do business. We are thrilled to be partnering with NewHold. As NHIC is already listed on NASDAQ, Evolv will become a public company when the deal is complete, trading on NASDAQ under the new ticker symbol EVLV. The boards of directors of both Evolv and NHIC have unanimously approved the proposed transaction, which is expected to be completed in Q2 of 2021.

There is work to be done in order to close this transaction. Once the merger is closed, it will deliver significant financial resources to accelerate our strategic growth plans, and substantially enhance our balance sheet. With the proceeds we are raising from this transaction, we will be armed with the capital necessary to accelerate and build upon our leadership position, transforming the physical security world to improve the safety and well-being of our customers and their visitors, employees and students all over the world.

As we enter this new chapter, there are some rules we must all follow. The SEC has strict guidelines governing publicity. To avoid delays or any other repercussions the SEC might impose if we do not adhere to these rules, we must avoid speaking publicly about this process and our business metrics and financials. Accordingly, I ask that you refrain from making statements about our company or the proposed transaction in open forums (e.g., online, to friends, on Facebook, Twitter, LinkedIn, via email, to existing or prospective clients, to the press, etc.).

If you are asked about the process of going public or company fundamentals, we would ask you to decline offering any comment.

Should you receive any press inquiries, please forward details of the inquiry to Dana Loof - 415.244.7863 or dloof@evolvtechnology.com - who can help handle media requests appropriately during this sensitive time. Understanding that communications are highly regulated through this process, please know that we will continue to share updates with you as we have more to report.

We look forward to continuing our work together in this next phase of our business evolution, as we continue to drive toward our mission.

Thank you for all that you do for Evolv.

Peter and Anil

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.
