This document includes “forward-looking statements” within the meaning of the federal securities laws with respect to the proposed transaction between Grab Holdings Inc. (“Grab”), Grab Holdings Limited (“GHL”) and AGC and regarding Grab’s future business expectations which involve risks and uncertainties. All statements other than statements of historical fact contained in this document, including, but not limited to, statements as to future results of operations and financial position, planned products and services, business strategy and plans, objectives of management for future operations of Grab, market size and growth opportunities, competitive position, technological and market trends and the potential benefits and expectations related to the terms and timing of the proposed transactions, are forward-looking statements. Some of these forward-looking statements can be identified by the use of forward-looking words, including “anticipate,” “expect,” “suggests,” “plan,” “believe,” “intend,” “estimates,” “targets,” “projects,” “should,” “could,” “would,” “may,” “will,” “forecast” or other similar expressions. All forward-looking statements are based upon estimates and forecasts and reflect the views, assumptions, expectations, and opinions of AGC and Grab, which are all subject to change due to various factors including, without limitation, changes in general economic conditions as a result of COVID-19. Any such estimates, assumptions, expectations, forecasts, views or opinions, whether or not identified in this document, should be regarded as indicative, preliminary and for illustrative purposes only and should not be relied upon as being necessarily indicative of future results.

The forward-looking statements contained in this document are subject to a number of factors, risks and uncertainties, some of which are not currently known to Grab or AGC. You should carefully consider the foregoing factors and the other risks and uncertainties described in the “Risk Factors” section of GHL’s registration statement on Form F-4, the proxy statement/ prospectus therein, AGC’s Quarterly Report on Form 10-Q and other documents filed by GHL or AGC from time to time with the U.S. Securities and Exchange Commission.

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. In addition, there may be additional risks that neither AGC nor Grab presently know, or that AGC or Grab currently believe are immaterial, that could also cause actual results to differ from those contained in the forward-looking statements. Forward-looking statements reflect AGC’s and Grab’s expectations, plans, projections or forecasts of future events and view. If any of the risks materialize or AGC’s or Grab’s assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements.

Forward-looking statements speak only as of the date they are made. AGC and Grab anticipate that subsequent events and developments may cause their assessments to change. However, while GHL, AGC and Grab may elect to update these forward-looking statements at some point in the future, GHL, AGC and Grab specifically disclaim any obligation to do so, except as required by law. The inclusion of any statement in this document does not constitute an admission by Grab nor AGC or any other person that the events or circumstances described in such statement are material. These forward-looking statements should not be relied upon as representing AGC’s or Grab’s assessments as of any date subsequent to the date of this document. Accordingly, undue reliance should not be placed upon the forward-looking statements. In addition, the analyses of Grab and AGC contained herein are not, and do not purport to be, appraisals of the securities, assets or business of Grab, AGC or any other entity.
