Important Information for Investors and Shareholders

NewHold and NewCleo intend to file with the Securities and Exchange Commission (the “SEC”) a Registration Statement on Form F-4 (as may be amended, the “Registration Statement”), which will include a preliminary proxy statement of NewHold and a prospectus of NewCleo (the “Proxy Statement/Prospectus”) in connection with the Business Combination, the private placements of securities in connection with the Business Combination, if any (the “Private Placement Transactions”), and the other transactions contemplated by the Business Combination Agreement and/or as described in this Form 8-K (together with the Business Combination and the Private Placement Transactions, the “Proposed Transactions”). The definitive proxy statement and other relevant documents will be mailed to shareholders of NewHold as of the record date to be established for voting on the Business Combination and other matters as described in the Proxy Statement/Prospectus. NewHold and/or NewCleo will also file other documents regarding the Proposed Transactions with the SEC. This Form 8-K does not contain all of the information that should be considered concerning the Proposed Transactions and is not intended to form the basis of any investment decision or any other decision in respect of the Proposed Transactions. BEFORE MAKING ANY VOTING OR INVESTMENT DECISION, SHAREHOLDERS OF NEWHOLD AND OTHER INTERESTED PARTIES ARE URGED TO READ, WHEN AVAILABLE, THE PRELIMINARY PROXY STATEMENT/PROSPECTUS, AND AMENDMENTS THERETO, AND THE DEFINITIVE PROXY STATEMENT/PROSPECTUS AND ALL OTHER RELEVANT DOCUMENTS FILED OR THAT WILL BE FILED WITH THE SEC IN CONNECTION WITH NEWHOLD’S SOLICITATION OF PROXIES FOR THE EXTRAORDINARY GENERAL MEETING OF ITS SHAREHOLDERS TO BE HELD TO APPROVE THE PROPOSED TRANSACTIONS AND OTHER MATTERS AS DESCRIBED IN THE PROXY STATEMENT/PROSPECTUS BECAUSE THESE DOCUMENTS WILL CONTAIN IMPORTANT INFORMATION ABOUT NEWHOLD, NEWCLEO AND THE PROPOSED TRANSACTIONS. Investors and security holders will also be able to obtain copies of the Registration Statement and the Proxy Statement/Prospectus and all other documents filed or to be filed with the SEC by NewHold and NewCleo, without charge, once available, on the SEC’s website at www.sec.gov, or by directing a request to: NewHold Investment Corp. III, 52 Vanderbilt Avenue, Suite 2005, New York, New York 10017, or to: NewCleo Ltd., 55 South Audley Street London, W1K 2QH, United Kingdom.

A list of the names of NewHold’s directors and executive officers and information regarding their interests in the Business Combination and their ownership of NewHold’s securities is, or will be, contained in NewHold’s filings with the SEC. Additional information regarding the interests of the persons who may, under SEC rules, be deemed participants in the solicitation of proxies from NewHold shareholders in connection with the Business Combination, including the names and interests of NewCleo’s directors and executive officers, will be set forth in the Proxy Statement/Prospectus, which is expected to be filed by NewHold and NewCleo with the SEC. Investors and security holders may obtain free copies of these documents as described above.

No offer of securities shall be made except by means of a prospectus meeting the requirements of the Securities Act or an exemption therefrom. Investors should consult with their counsel as to the applicable requirements for a purchaser to avail itself of any exemption under the Securities Act.

All statements contained in this Form 8-K other than statements of historical fact, including, without limitation, statements regarding the Business Combination between NewHold and NewCleo; the anticipated benefits and timing of the transaction; expected trading of the combined company’s securities on Nasdaq; the completion of investments from certain institutional investors; the expected amount of gross proceeds from any investments or other financing arrangements; the anticipated use of proceeds from such investments or financing arrangements; NewCleo’s development and commercialization of its lead-cooled fast reactor technology, mixed-oxide fuel capabilities and related products and services; the expected timing, cost, performance and benefits of NewCleo’s demonstration projects, fuel facilities, reactor deployments and licensing activities; NewCleo’s ability to execute its business strategy, develop its technology, obtain required regulatory approvals, permits and licenses, enter into commercial arrangements, achieve its market opportunity and positioning and support the growth of advanced nuclear energy; NewCleo’s expectations regarding strategic partnerships, customer demand, project pipeline, revenue streams, capital expenditures and financing needs; and other statements regarding management’s intentions, beliefs, or expectations with respect to the combined company’s future performance, are forward-looking statements.

Such risks and uncertainties include, but are not limited to: (1) the occurrence of any event, change or other circumstances that could delay or prevent the consummation of the proposed Business Combination; (2) the outcome of any legal proceedings that may be instituted against NewHold, NewCleo, the combined company, or others following the announcement of the Proposed Transactions; (3) the inability to complete the Business Combination due to failure to obtain NewHold shareholder approval or satisfy other closing conditions; (4) the inability to complete any Private Placement Transactions or other financing arrangements on the expected terms, or at all; (5) changes to the structure, timing or terms of the Proposed Transactions; (6) the ability of the combined company to meet applicable listing standards or to maintain the listing of its securities following the closing of the Business Combination; (7) the risk that the announcement and consummation of the transaction disrupts current plans, operations, relationships with customers, suppliers, regulators, partners and employees, or NewCleo’s ability to retain key personnel; (8) the ability to recognize the anticipated benefits of the Business Combination, including the ability to fund and execute NewCleo’s technology development, licensing, manufacturing, fuel supply and commercialization plans; (9) risks related to NewCleo’s early stage of development, limited operating history and expected need for substantial additional capital to develop, license, construct and commercialize its technologies and facilities; (10) risks related to the development, demonstration, licensing and deployment of advanced nuclear technologies, including NewCleo’s lead-cooled fast reactor technology and mixed-oxide fuel strategy; (11) risks related to technical performance, engineering, manufacturing, construction, supply chain, fuel availability, cost estimates, project delays, cost overruns, corrosion, materials performance, safety, reliability and other development or operational challenges; (12) risks related to obtaining, maintaining or complying with required regulatory approvals, permits, authorizations, licenses and export control approvals in the United States, the United Kingdom, France, Italy, the European Union and other jurisdictions in which NewCleo may operate; (13) changes in market, regulatory, political and economic conditions affecting the nuclear energy industry, advanced reactor development, energy markets, capital markets and infrastructure financing; (14) the costs related to the Proposed Transactions and those arising as a result of becoming a public company; (15) the level of redemptions of NewHold’s public shareholders, which may reduce the amount of cash available to the combined company and may reduce the public float of, reduce the liquidity of the trading market of, and/or maintain the quotation, listing or trading of securities of NewHold or NewCleo; (16) risks related to increased competition in the industries in which NewCleo will operate; (17) risks related to changes in U.S. or foreign laws and regulations applicable to nuclear energy, export controls, sanctions, trade restrictions, foreign investment, environmental protection, health and safety, securities and public company reporting; (18) the possibility that the combined company may be adversely affected by competitive factors, investor sentiment, litigation, cybersecurity incidents, geopolitical developments or other macroeconomic conditions; (19) the risk of being considered to be a “shell company” by any stock exchange on which NewCleo securities will be listed or by the SEC, which may impact the ability to list NewCleo’s securities and restrict reliance on certain rules or forms in connection with the offering, sale or resale of securities; and (20) other risks detailed from time to time in NewHold’s filings with the SEC, including the Registration Statement and related documents filed or to be filed in connection with the Business Combination.

The foregoing list of risk factors is not exhaustive.

These filings do or will identify and address other important risks and uncertainties that could cause actual results to differ materially from those contained in the forward-looking statements. Additional risks and uncertainties not currently known or that are currently deemed immaterial may also cause actual results to differ materially from those expressed or implied by such forward-looking statements. Readers are cautioned not to put undue reliance on forward-looking statements, and none of the parties or any of their representatives assumes any obligation or intends to update or revise these forward-looking statements, each of which is made only as of the date of this Form 8-K.
