Form F-4 regulatory

"filed a registration statement on Form F-4 with the SEC"

Form F-4 is an official filing with the U.S. Securities and Exchange Commission used by non-U.S. companies when they offer securities in connection with mergers, acquisitions, exchange offers or similar transactions. It acts like a detailed product label or instruction manual that explains the deal, the securities being offered, financials, risks and voting requirements, and it matters to investors because it provides the essential facts needed to evaluate how the transaction could affect ownership, value and future returns.

proxy statement/prospectus regulatory

"definitive proxy statement/prospectus will be sent to all Legato shareholders"

A proxy statement or prospectus is a document that companies send to shareholders to provide important information about upcoming decisions or investments, such as voting on company issues or offering new shares to the public. It helps investors understand the details and risks involved, enabling them to make informed choices about their ownership or involvement with the company.

forward-looking statements regulatory

"This communication contains certain "forward-looking statements" within the meaning"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

solicitation of proxies regulatory

"may be deemed to be participants in the solicitation of proxies from Legato's shareholders"

Solicitation of proxies is the process by which a company or a shareholder asks other shareholders to authorize their votes on corporate matters by signing or submitting a proxy form. Think of it like asking friends to sign a permission slip on your behalf so a decision can be made without everyone attending; it matters to investors because proxy campaigns determine control of the board, approval of major deals or policies, and can signal contested management battles that affect share value and strategy.

Forward-Looking Statements

This communication contains certain “forward-looking statements” within the meaning of U.S. federal securities laws including, but not limited to, statements regarding the Transaction with Legato and Einride’s expected and potential ARR, as applicable. 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 based on current expectations and assumptions available to the Company and Legato, and, as a result, are subject to risks and uncertainties. Any such expectations and assumptions, whether or not identified in this communication, should be regarded as preliminary and for illustrative purposes only and should not be relied upon as being necessarily indicative of future results. Many factors could cause actual future events to differ materially from the forward-looking statements in this communication, including but not limited to: (1) the occurrence of any event, change or other circumstances that could give rise to the termination of definitive agreements with respect to the Transaction; (2) the outcome of any legal proceedings that may be instituted against Legato, Einride, the combined company or others following the announcement of the Transaction and any definitive agreements with respect thereto; (3) the amount of redemption requests made by Legato public shareholders and the inability to complete the Transaction due to the failure to obtain approval of the shareholders of Legato, to obtain financing to complete the Transaction or to satisfy other conditions to closing; (4) risks related to the scaling of the Company’s business and the timing of expected business milestones; (5) the ability to meet stock exchange listing standards following the consummation of the Transaction; (6) the risk that the Transaction disrupts current plans and operations of the Company as a result of the announcement and consummation of the Transaction; (7) the ability to recognize the anticipated benefits of the business combination, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, maintain relationships with customers and suppliers and retain its management and key employees; (8) costs related to the Transaction; (9) risks associated with changes in laws or regulations applicable to the Company’s solutions and services and the Company’s international operations; (10) the possibility that the Company or the combined company may be adversely affected by other economic, geopolitical, business, and/or competitive factors; (11) supply shortages in the materials necessary for the production of Einride’s solutions; (12) negative perceptions or publicity of the Company; (13) risks related to working with third-party manufacturers for key components of Einride’s solutions; (14) the termination or suspension of any of Einride’s contracts or the reduction in counterparty spending; and (15) the ability of Einride or the combined company to issue equity or equity- linked securities in connection with the Transaction or in the future.

Forward-looking statements are not guarantees of future performance. You should carefully consider the foregoing factors and the other risks and uncertainties that are described in the “Risk Factors” section of the Registration Statement filed by the Company with SEC, and other documents filed by the Company and/or Legato 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 all forward-looking statements in this communication are qualified by these cautionary statements. The Company and Legato 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, except to the extent required by applicable law. Neither the Company nor Legato gives any assurance that either the Company or Legato will achieve its expectations.
