"We are pleased to report that second quarter financial and operating results continued their path of strong performance,as we consistently implemented our strategy in K-12 one-on-one mass-market offerings,particularly in the non-tier-one cities[3]," said Mr. Jack Jiajia Huang,Founder,Chairman and Chief Executive Officer of 51Talk. "Both net revenues and gross billings exceeded the high end of our second quarter guidance range,firmly led by our K-12 mass-market one-on-one gross billings which reached RMB418.5 million,representing a 50.5% year-over-year increase,and accounted for 84.0% of our total gross billings.

"In addition to strong top-line performance,our balanced approach to both growth and profitability continues to bear positive results. Our Non-GAAP net loss for the second quarter narrowed further to RMB26.7 million,from a loss of RMB59.5 million in the first quarter,representing an improvement of net margin to negative 7.6% from negative 18.4%. The historically low Non-GAAP net loss can be credited to our focus on teaching quality,student satisfaction,and our continued pursuit to optimize operational efficiency and improve profitability. I am very proud to share that we successfully delivered over 90 million one-on-one online English lessons,which also include free trial lessons,from our inception in 2011 through the end of August this year. This is a nice milestone to mark in our vision to empower everyone to talk to the world. Going forward,we will continue to strengthen our core K-12 mass-market one-on-one business in non-tier-one cities by offering high-quality programs coupled with best-in-class technology," Mr. Huang concluded.

Mr. Min Xu,Chief Financial Officer of 51Talk,added,"Second quarter saw continued focus on the comprehensive execution of our operating model with a sharp emphasis on cost efficiency and the pursuit of profitability. We achieved historically high cash flow from operations of RMB99.2 million in the second quarter,a 265.8% year-over-year increase from RMB27.1 million in the same quarter last year. Consolidated gross margin expanded by 3.9 percentage points year-over-year to 69.6%,driven by significant gross margin improvement of both our one-on-one and small class offerings. With our focused growth strategy targeting non-tier-one cities and continued optimization of operating efficiencies,we are confident we can continue to deliver healthy growth and improve our profitability in the second half of 2019."

Impact of Recently Adopted New Accounting Standard

In February 2016,the FASB issued ASU 2016-02 "Leases",which generally requires lessees to recognize operating and financing lease liabilities and corresponding right-of-use assets on the balance sheet and to provide enhanced disclosures surrounding the amount,timing and uncertainty of cash flows arising from leasing arrangements. The Company adopted the new standard on January 1,2019 on a modified retrospective basis and did not restate comparative periods. The Company recognized approximately RMB55.8 million as total right-of-use assets and RMB54.2 million astotal lease liabilities for the operating leases on its consolidated balance sheet as of January 1,2019. The Company recognized RMB48.2 million and RMB46.1 million as total right-of-use assets and total lease liabilities,respectively,for the operating leases on its consolidated balance sheet as of June30,2019. Other than the foregoing,the new lease standard did not have a material impact on the Company's consolidated financial statements.

Outlook

For thethird quarter of 2019,the Company currently expects:

Net revenues to be between RMB395 million to RMB400 million,which would represent an increase of approximately 30.3% to 31.9% from RMB303.2 million for the same quarter last year;

Total gross billings to be between RMB513 million to RMB518 million,which would represent an increase of approximately 20.8% to 22.0% from RMB424.5 million for the same quarter last year.

Gross billings for the Company's one-on-one business are expected to be between RMB505 million to RMB510 million,which would represent an increase of approximately 23.8% to 25.0% from RMB407.9 million for the same quarter last year.

Gross billings for 51Talk's small class business are expected to be approximately RMB8 million,which would represent a decrease of approximately 51.8% from RMB16.6 million for the same quarter last year.

The above outlook is based on the current market conditions and reflects the Company's current and preliminary estimates of market and operating conditions and customer demand,which are all subject to change.

Use of Non-GAAP Financial Measures

In evaluating its business,51Talk considers and uses the following measures defined as non-GAAP financial measures by the SEC as supplemental metrics to review and assess its operating performance: non-GAAP sales and marketing expenses,non-GAAP product development expenses,non-GAAP general and administrative expenses,non-GAAP operating expenses,non-GAAP loss from operations,non-GAAP income tax expenses,non-GAAP net loss,non-GAAP net loss attributable to ordinary shareholders,and non-GAAP net loss attributable to ordinary shareholders per share and per ADS. To present each of these non-GAAP measures,the Company excludes share-based compensation expenses. The presentation of these non-GAAP financial measures is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP. For more information on these non-GAAP financial measures,please see the table captioned "Reconciliations of non-GAAP measures to the most comparable GAAP measures" set forth at the end of this press release.

51Talk believes that these non-GAAP financial measures provide meaningful supplemental information regarding its performance by excluding share-based expenses that may not be indicative of its operating performance from a cash perspective. 51Talk believes that both management and investors benefit from these non-GAAP financial measures in assessing its performance and when planning and forecasting future periods. These non-GAAP financial measures also facilitate management's internal comparisons to 51Talk's historical performance. 51Talk computes its non-GAAP financial measures using the same consistent method from quarter to quarter and from period to period. 51Talk believes these non-GAAP financial measures are useful to investors in allowing for greater transparency with respect to supplemental information used by management in its financial and operational decision-making. A limitation of using non-GAAP measures is that these non-GAAP measures exclude share-based compensation expenses that have been and will continue to be for the foreseeable future a significant recurring expense in the 51Talk's business. Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from each non-GAAP measure. The accompanying table at the end of this press release provides more details on the reconciliations between GAAP financial measures that are most directly comparable to non-GAAP financial measures.
