About Grab

Grab is Southeast Asia’s leading superapp based on GMV in 2020 in each of food deliveries, mobility and the e-wallets segment of financial services, according to Euromonitor. Grab operates across the deliveries, mobility and digital financial services sectors in over 400 cities in eight countries in the Southeast Asia region - Cambodia, Indonesia, Malaysia, Myanmar, the Philippines, Singapore, Thailand and Vietnam. Grab enables millions of people each day to access its driver- and merchant-partners to order food or groceries, send packages, hail a ride or taxi, pay for online purchases or access services such as lending, insurance, wealth management and telemedicine, all through a single “everyday everything” app. Grab was founded in 2012 with the mission to drive Southeast Asia forward by creating economic empowerment for everyone, and since then, the Grab app has been downloaded onto millions of mobile devices. Grab strives to serve a double bottom line: to simultaneously deliver financial performance for its shareholders and a positive social impact in Southeast Asia.

The announced financial results conference call may include “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 Altimeter Growth Corp. (“AGC”) and regarding Grab’s future business expectations which involve risks and uncertainties. All statements other than statements of historical fact contained in the conference call, 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 the announced conference call 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 (the “SEC”).

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 the conference call 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 the conference call. Accordingly, undue reliance should not be placed upon the forward-looking statements.
