Momo Announces Unaudited Financial Results for the First Quarter of 2021

BEIJING, CHINA, June 8, 2021 – Momo Inc. (NASDAQ: MOMO) (“Momo” or the “Company”), a leading mobile social and entertainment platform in China, today announced its unaudited financial results for the first quarter of 2021.

First Quarter of 2021 Highlights

“The first quarter of 2021 was a good quarter and a decent start to the year 2021”, commented Li Wang, CEO of Momo. “We have stepped up our efforts to drive towards the strategic priorities that I set for my team at the beginning of the year. The initiatives we took have started bearing fruits. Despite the negative seasonality MAU reaching a record high, Momo core is on a steady improving trend and will continue to be a very productive and evolving cash cow business. This leaves us ample room to invest in new endeavors beyond Momo and Tantan. I am excited about the growth opportunities that we are seeing in Tantan and have put together a solid plan to unleash their full potential going forward.”

First Quarter of 2021 Financial Results

Net revenues

Total net revenues were RMB3,470.6 million (US$529.7 million) in the first quarter of 2021, a decrease of 3.4% from RMB3,594.1 million in the first quarter of 2020.

1

Live video service revenues were RMB1,962.1 million (US$299.5 million) in the first quarter of 2021, a decrease of 15.9% from RMB2,332.0 million during the same period of 2020. The decrease was primarily due to our structural reform on Momo’s core live video business, which was used to revive the long tail content ecosystem. The decrease was partially offset by the growth from Tantan’s live video service, and live video service revenues from Tantan were RMB251.2 million (US$38.3 million) in the first quarter of 2021,compared to RMB6.1 million in the same period of 2020.

Value-added service revenues mainly include virtual gift revenues and membership subscription revenues. Total value-added service revenues were RMB1,455.5 million (US$222.2 million) in the first quarter of 2021, an increase of 23.8% from RMB1,175.8 million during the same period of 2020. The year-over-year increase was primarily attributable to the continued growth of the virtual gift business on the Momo application driven by more innovative products and operational ideas launched, and more paying scenarios introduced to enhance the social entertainment experience of Momo users, and to a lesser extent, the increase in the virtual gift revenues of new applications. The increase was partially offset by the decrease in the membership subscription revenues of Tantan, due to the decrease of paying users of Tantan.

Mobile marketing revenues were RMB38.7 million (US$5.9 million) in the first quarter of 2021, a decrease of 32.3% from RMB57.2 million during the same period of 2020. The decrease in mobile marketing revenues was primarily caused by our strategy to underweight the line in terms of resource allocation.

Mobile games revenues were RMB11.2 million (US$1.7 million) in the first quarter of 2021, a decrease of 11.9% from RMB12.7 million in the first quarter of 2020. The decrease in mobile game revenues was mainly due to the continued decrease in quarterly paying users of mobile games.

Net revenues from the Momo segment decreased from RMB3,202.1 million in the first quarter of 2020 to RMB2,901.8 million (US$442.9 million) in the first quarter of 2021, primarily due to the decrease in net revenues from live video service, partially offset by the increase in net revenues from value-added service. Net revenues from the Tantan segment increased from RMB381.7 million in the first quarter of 2020 to RMB567.7 million (US$86.6 million) in the first quarter of 2021, which was mainly due to the increase in net revenues from live video service.

Cost and expenses

Cost and expenses were RMB3,016.3 million (US$460.4 million) in the first quarter of 2021, a decrease of 0.3% from RMB3,026.1 million in the first quarter of 2020. The decrease was primarily attributable to: (a) a decrease in revenue sharing with broadcasters related to Momo’s core live video service; (b) a decrease in marketing and promotional expenses to promote our core live video services and attract users on Tantan; (c) a decrease in commission fees paid to payment channels. These decreases were partially offset by an increase in revenue sharing with virtual gift recipients for our virtual gift service, and an increase in revenue sharing with broadcasters related to Tantan’s live video service.

Non-GAAP cost and expenses (note 1) were RMB2,835.3 million (US$432.8 million) in the first quarter of 2021, an increase of 0.6% from RMB2,819.2 million during the same period of 2020.

Income tax expenses

Income tax expenses were RMB91.4 million (US$14.0 million) in the first quarter of 2021, decreasing from RMB162.9 million in the first quarter of 2020. The decrease in income tax expenses was mainly due to the lower profit and tax refund resulted from additional expense deduction related to previous year in the first quarter of 2021.

Note 1: Non-GAAP measures

To supplement our consolidated financial statements presented in accordance with U.S. generally accepted accounting principles (“GAAP”), we use various non-GAAP financial measures that are adjusted from the most comparable GAAP results to exclude share-based compensation and amortization of intangible assets from business acquisitions, and tax impacts related to the amortization of intangible assets from business acquisitions.

Reconciliations of our non-GAAP financial measures to our U.S. GAAP financial measures are shown in tables at the end of this earnings release, which provide more details about the non-GAAP financial measures.

Our non-GAAP financial information is provided as additional information to help investors compare business trends among different reporting periods on a consistent basis and to enhance investors’ overall understanding of the historical and current financial performance of our continuing operations and our prospects for the future. Our non-GAAP financial information should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for or superior to the GAAP results. In addition, our calculation of the non-GAAP financial measures may be different from the calculation used by other companies, and therefore comparability may be limited.

Our non-GAAP information (including non-GAAP cost and operating expenses, income (loss) from operations, net income (loss), net income attributable to Momo Inc., and diluted net income per ADS) is adjusted from the most comparable GAAP results to exclude share-based compensation, amortization of intangible assets from business acquisitions, and tax impacts related to the amortization of intangible assets from business acquisitions. A limitation of using these non-GAAP financial measures is that share-based compensation, amortization of intangible assets from business acquisitions and tax impacts related to the amortization of intangible assets from business acquisitions have been and will continue to be for the foreseeable future a significant recurring expense in our results of operations. We compensate for these limitations by providing reconciliations of our non-GAAP measures to our U.S. GAAP measures. Please see the reconciliation tables at the end of this earnings release.
