Amendment Description	On February 6, 2020, Telenav, Inc. (the “Company”) issued a press release announcing its financial results for the three months ended December 31, 2019. The Company also issued a related investor presentation (which the Company also posted on its website), and hosted an investor conference call and webcast, wherein the Company commented on operating results for the Company’s three months ended December 31, 2019 and provided outlook for the three months ending March 31, 2020. Subsequent to the issuance of the press release and related investor presentation (attached to the Form 8-K dated February 6, 2020 as Exhibits 99.1 and 99.2, respectively), and conference call and webcast with investors, the Company further reviewed and updated its reporting of revenue related to its agreements with Grab Holdings, Inc. and certain of its subsidiaries (as further defined below, the “Grab Transaction,” and Grab, together with its certain subsidiaries, collectively “Grab”). This updated revenue related to the Grab Transaction affects the three months ended September 30, 2019 and the three and six months ended December 31, 2019, as well as the outlook the Company provided on February 6, 2020 for the three months ending March 31, 2020.
