Three Months Ended June 30, 2021 Compared to Three Months Ended June 30, 2020

Revenue

Our total GAAP revenue increased by 158.6% to US$2.3 billion in the second quarter of 2021 from US$882.0 million in the second quarter of 2020. The increase was mainly driven by the growth in each of the segments detailed as follows:

Cost of Revenue

Our total cost of revenue increased by 98.1% to US$1.3 billion in the second quarter of 2021 from US$681.2 million in the second quarter of 2020.

Other Operating Income

Our other operating income increased by 120.8% to US$72.0 million in the second quarter of 2021 from US$32.6 million in the second quarter of 2020. The increase was mainly attributable to the rebates from e-commerce related logistics services providers.

Sales and Marketing Expenses

Our total sales and marketing expenses increased by 138.5% to US$921.4 million in the second quarter of 2021 from US$386.3 million in the second quarter of 2020. The table below sets forth breakdown of the sales and marketing expenses of our major reporting segments. Amounts are expressed in thousands of US dollars (“$”).

General and Administrative Expenses

Our general and administrative expenses increased by 68.1% to US$243.0 million in the second quarter of 2021 from US$144.5 million in the second quarter of 2020. This increase was primarily due to higher staff compensation and benefit costs from increased staff to support the business growth, office facilities and related expenses, as well as credit losses for our digital financial services business.

Research and Development Expenses

Our research and development expenses increased by 129.0% to US$172.6 million in the second quarter of 2021 from US$75.3 million in the second quarter of 2020, primarily due to the increase in research and development staff force.

Non-operating Income or Losses, Net

Non-operating income or losses mainly consist of interest income, interest expense, investment gain (loss) and foreign exchange gain (loss). We recorded a net non-operating loss of US$25.1 million in the second quarter of 2021, compared to a net non-operating income of US$7.6 million in the second quarter of 2020. Our non-operating loss in the second quarter of 2021 was primarily due to interest expenses on our outstanding convertible notes.

Income Tax Expense

We had a net income tax expense of US$75.2 million and US$27.8 million in the second quarter of 2021 and 2020, respectively. The income tax expense in the second quarter of 2021 was primarily due to corporate income tax and withholding tax expenses incurred by our digital entertainment segment.

Non-GAAP Financial Measures

To supplement our consolidated financial statements, which are prepared and presented in accordance with U.S. GAAP, we use the following non-GAAP financial measures to help evaluate our operating performance:

These non-GAAP financial measures have limitations as analytical tools. None of the above financial measures should be considered in isolation or construed as an alternative to revenue, net loss/income, or any other measure of performance or as an indicator of our operating performance. These non-GAAP financial measures presented here may not be comparable to similarly titled measures presented by other companies. Other companies may calculate similarly titled measures differently, limiting their usefulness as comparative measures to Sea’s data. We compensate for these limitations by reconciling the non-GAAP financial measures to their nearest U.S. GAAP financial measures, all of which should be considered when evaluating our performance. We encourage you to review our financial information in its entirety and not rely on any single financial measure.
