As previously disclosed, on November 12, 2025, Legato Merger Corp. III, a Cayman Islands exempted company (the "Company"), Einride AB, a limited liability company formed under the laws of Sweden ("Einride"), and Einride Cayman Sub Limited, a Cayman Islands exempted company and a direct, wholly-owned subsidiary of Einride ("Merger Sub"), entered into a Business Combination Agreement ("BCA"). Pursuant to the BCA, the Company will merge with and into Merger Sub, with Merger Sub surviving the merger ("Merger"). As a result of the Merger, Merger Sub will continue as a direct, wholly-owned subsidiary of Einride, with the shareholders of the Company becoming shareholders of Einride.

On May 5, 2026, the Company held an extraordinary general meeting (the "Meeting") to approve the following resolutions:

	●	to resolve as a special resolution, that the Company's amended and restated memorandum and articles of association as adopted by special resolution dated February 5, 2024 with effect from February 5, 2024 be amended pursuant to which the board of directors of the Company may extend the date by which the Company must consummate a business combination on a monthly basis, up to three (3) months (or until August 8, 2026), unless the closing of a business combination shall have occurred prior thereto or such earlier date as shall be determined by the Board in its sole discretion, provided that Einride or another mutually agreed upon third party on behalf of Einride or the Company, including but not limited to each of their respective officers, directors, affiliates or designees, lends to the Company $0.03 per public share outstanding on such date for each month extension utilized to consummate an initial business combination and such funds are deposited into the trust account established by the Company in connection with its initial public offering (the "Extension Proposal").
	●	to resolve as an ordinary resolution, that the adjournment of the Extraordinary General Meeting to a later date or dates, if necessary, to approve the Extension Proposal be approved (the "Adjournment Proposal").

An aggregate of 21,845,115 ordinary shares of the Company, which represented a quorum of the outstanding ordinary shares entitled to vote as of the record date of March 30, 2026, were represented in person or by proxy at the Meeting.

The Company's shareholders voted on the proposals at the Meeting, which were approved as follows:

(1)

Proposal No. 1 - The Extension Proposal

For		Against		Abstain		Broker Non-Votes
21,835,897		5,782		3,436		0

Because quorum was obtained and the Extension Proposal was approved, the Company did not hold a vote on the Adjournment Proposal.

The amendments to the Amended and Restated Memorandum and Articles of Association of the Company to be filed with the Cayman Islands Registrar of Companies to effectuate the foregoing are attached hereto as Exhibit 3.1.

In connection with the Meeting, holders of an aggregate of 3,233,391 public shares of the Company exercised their right to have their shares redeemed for a pro rata amount held in the Company's trust account, or an aggregate of approximately $35.7 million (approximately $11.04 per share). As a result, an aggregate of 16,891,609 public shares remained outstanding following the Meeting.

As required by the Extension Proposal, an aggregate of $506,748.27, representing the payment for the first monthly extension described above, has been deposited into the trust account.

The Company is continuing to attempt to consummate its business combination with Einride.

Cautionary Note Regarding Forward Looking Statements

Neither Legato, Einride nor any of their respective affiliates makes any representation or warranty as to the accuracy or completeness of the information contained in this Current Report on Form 8-K. This Current Report on Form 8-K is not intended to be all-inclusive or to contain all the information that a person may desire in considering the proposed Transactions discussed herein. It is not intended to form the basis of any investment decision or any other decision in respect of the proposed Transactions.

This Current Report on Form 8-K and the exhibits filed or furnished herewith include certain "forward-looking statements" within the meaning of the federal securities laws with respect to the proposed transaction between Legato and Einride, including statements regarding the benefits of the transaction, Einride's or Legato's expectations with respect to future performance, the addressable market for Einride's solutions and services, capitalization of Einride after giving effect to the transaction, the percentage of the Company's shareholders' ownership interest in the equity of the combined company following the closing of the transaction, Einride's expected investments in the U.S. market, the anticipated timing of the Transactions, the business of Einride and the markets in which it operates. Legato's and Einride's actual results may differ from their expectations, estimates and projections and consequently, you should not rely on these forward-looking statements as predictions of future events. These forward-looking statements generally are identified by the words "aspire," "expect," "estimate," "project," "budget," "forecast," "anticipate," "intend," "plan," "may," "will," "will be," "will continue," "will likely result," "could," "should," "would," "believe(s)," "predicts," "potential," "continue," "future," "opportunity," "strategy," and similar expressions are intended to identify such forward-looking statements.

Forward-looking statements are their managements' current predictions, projections and other statements about future events that are based on current expectations and assumptions available to Einride and Legato, and, as a result, are subject to risks and uncertainties. Any such expectations and assumptions, whether or not identified in this Current Report on Form 8-K. should be regarded as preliminary and for illustrative purposes only and should not be relied upon as being necessarily indicative of future results. These forward-looking statements involve significant risks and uncertainties that could cause the actual results to differ materially from the expected results. Most of these factors are outside Legato's and Einride's control and are difficult to predict. Factors that may cause such differences include, but are not limited to: the risk that the benefits of the Merger may not be realized; the risk that the Merger may not be completed in a timely manner or at all, which may adversely affect the price of Legato's securities; the amount of redemption requests made by Legato public shareholders and the failure to satisfy the conditions to the consummation of the Merger, including the failure of Legato's shareholders to approve and adopt the Merger; risks related to the scaling of the Company's business and the timing of expected business milestones; the ability to meet stock exchange listing standards following the consummation of the Merger; the occurrence of any event, change or other circumstance that could give rise to the termination of the BCA; the outcome of any legal proceedings that may be initiated following announcement of the Merger; the combined company's continued listing on the Exchange; the risk that the proposed transaction disrupts current plans and operations of Einride as a result of the announcement and consummation of the Merger; the ability to recognize the anticipated benefits of the transaction, 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; costs related to the Merger; risks associated with changes in applicable laws or regulations applicable to Einride's solutions and services and Einride's international operations; the possibility that the combined company may be adversely affected by other economic, geopolitical, business, and/or competitive factors; supply shortages in the materials necessary for the production of Einride's solutions; negative perceptions or publicity of Einride; risks related to working with third-party manufacturers for key components of Einride's solutions; the termination or suspension of any of Einride's contracts or the reduction in counterparty spending; the ability of Einride or the combined company to issue equity or equity-linked securities in connection with the proposed business combination or in the future; the impact of adverse public health developments; and other risks and uncertainties that is detailed in the Proxy Statement/Prospectus (as defined below) and as indicated from time to time in Legato's filings 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.

Legato and Einride caution that the foregoing list of factors is not exclusive. Legato and Einride caution readers not to place undue reliance upon any forward-looking statements, which speak only as of the date made. Neither Legato nor Einride undertake or accept any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements to reflect any change in its expectations or any change in events, conditions or circumstances on which any such statement is based.

Forward-looking statements are not guarantees of future performance. You should carefully consider the foregoing factors and the other risks and uncertainties described in the "Risk Factors" section of Einride's registration statement on Form F-4 filed by Einride with the SEC (the "Form F-4"), and other documents filed by Einride 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 Current Report on Form 8-K are qualified by these cautionary statements. Einride 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 Einride nor Legato gives any assurance that either Einride or Legato will achieve its expectations. The inclusion of any statement in this Current Report on Form 8-K does not constitute an admission by Einride or Legato or any other person that the events or circumstances described in such statement are material.

Additional Information and Where to Find It

In connection with the proposed transaction between Einride and Legato, Einride has filed the Form F-4 with the SEC which includes Einride's prospectus as well as Legato's proxy statement (the "Proxy Statement/Prospectus").
