As previously disclosed, on November 12, 2025, Legato Merger Corp. III, a Cayman Islands exempted company (“Legato” or 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, which was amended by Amendment No. 1 to Business Combination Agreement, dated February 26, 2026, Amendment No. 2 to Business Combination Agreement, dated March 5, 2026, and Amendment No. 3 to Business Combination Agreement, dated April 17, 2026 (as amended, the “Business Combination Agreement”).

On June 9, 2026 (the “Closing Date”), pursuant to the Business Combination Agreement, Legato merged with and into Merger Sub, with Merger Sub surviving the merger as a direct, wholly-owned subsidiary of Einride (the “Merger”). The Merger and the other transactions contemplated by the Business Combination Agreement are referred to herein as the “Business Combination.” As a result of the Merger, Legato ceased to exist as a separate legal entity, and the securityholders of Legato became securityholders of Einride.

Immediately prior to the effective time of the Merger, each outstanding unit of Legato separated into its component securities, and the underlying ordinary shares and warrants were treated as described below. At the effective time of the Merger, each issued and outstanding ordinary share of Legato, par value $0.0001 per share, was automatically cancelled and converted into and exchanged for one ordinary share of Einride in the form of one American depositary share of Einride, each representing one ordinary share of Einride (an “ADS”). Each outstanding whole warrant of Legato was assumed by Einride (the “Einride Warrants”) and became exercisable to purchase one ordinary share of Einride in the form of one ADS.

In connection with the consummation of the Business Combination, Einride consummated its previously announced private placement of an aggregate of 12,235,420 ADSs for an aggregate purchase price of $113.3 million and issued warrants (the “PIPE Warrants”) to purchase an aggregate of 18,353,130 ADSs pursuant to subscription agreements entered into with certain investors. The PIPE Warrants are exercisable for ADSs at an exercise price of $10.90 per ADS, subject to adjustment as set forth therein, and expire five years after the date of issuance.

In connection with the extraordinary general meeting of Legato, holders of 16,596,675 ordinary shares of Legato exercised their right to redeem such shares for a pro rata portion of the funds in Legato’s trust account. After giving effect to such redemptions and the consummation of the Business Combination, Einride has 140,039,054 ordinary shares, of which 16,639,056 are represented by ADSs, and 10,340,313 Einride Warrants outstanding.

Following the consummation of the Business Combination, the ADSs and Einride Warrants commenced trading on The Nasdaq Stock Market LLC under the ticker symbols “ENRD” and “ENRDW,” respectively, on June 10, 2026.
