Jianpu Receives Notification from NYSE RegardingDelayed Form 20-F Filing

BEIJING, May 21, 2021— Jianpu Technology Inc. (“Jianpu” or the “Company”) (NYSE: JT), a leading independent open platform for discovery and recommendation of financial products in China, today announced that it received a notice dated May 18, 2021 from NYSE Regulation indicating that the Company is not in compliance with Section 802.01E of the NYSE Listed Company Manual as a result of its failure to timely file its Annual Report on Form 20-F for the year ended December 31, 2020 (the “2020 Form 20-F”) with the Securities and Exchange Commission (the “SEC”).

Jianpu was not able to file the 2020 Form 20-F within the prescribed period without unreasonable effort or expense. The preparation of the Company’s Annual Report on Form 20-F for the year ended December 31, 2019 (the “2019 Form 20-F”) was prolonged for the reasons previously disclosed, and the Company had not been in a position to prepare and finalize the 2020 Form 20-F before the 2019 Form 20-F was filed. The Company has filed the 2019 Form 20-F on April 30, 2021, and is making all efforts to prepare its financial statements and the related disclosures to file the 2020 Form 20-F as soon as possible.

NYSE Regulation notified the Company that the NYSE will closely monitor the status of the Company’s late filing and related public disclosures for up to a six-month period from the due date of the annual report. If the Company fails to file its annual report and any subsequent delayed filings within six months from the filing due date, the NYSE may, in its sole discretion, allow the Company’s securities to trade for up to an additional six months depending on specific circumstances, as outlined in Section 802.01E of the NYSE Listed Company Manual. It is expected by the NYSE that the Company will submit an official request for NYSE’s consideration at the appropriate time. If the NYSE determines that an additional six-month trading period is not appropriate, suspension and delisting procedures will commence pursuant to Section 804.00 of the NYSE Listed Company Manual.

Jianpu has also received a notice dated May 17, 2021 from NYSE Regulation acknowledging that the Company furnished its delayed Form 6-K containing the semi-annual financial information for the half year ended June 30, 2020 with the SEC on May 14, 2021 and cured the late filer status in relation to such delayed 6-K submission.
