“Recent turbulence in the industry and in the quarter had no material impact to our credit quality,” said Mr. Ryan Huanian Liu, Lexin’s chief risk officer. “The credit quality of our educated young adult customers continues to be stable — a reflection of the inherent low risk profile of this customer cohort. Our vintage charge-off rate6 continues to be approximately 2.0%, and our 90 day+ delinquency rate was 1.39% as of September 30, 2018.”

5 Non-GAAP EBIT and adjusted net income are non-GAAP financial measures. For more information on non-GAAP financial measures, please see the section of “Use of Non-GAAP Financial Measures Statement” and the tables captioned “Unaudited Reconciliations of GAAP and Non-GAAP Results” set forth at the end of this press release.

6 “Vintage charge-off rate” refers to, with respect to on- and off-balance sheet loans originated during a specified time period, which we refer to as a vintage, the total outstanding principal balance of the loans that are charged off during a specified period, divided by the total initial principal of the loans originated in such vintage.

Third Quarter 2018 Financial Results:

Operating revenue increased from RMB1.5 billion in the third quarter of 2017 to RMB1.7 billion in the third quarter of 2018. This increase in operating revenues was due to the increase in financial services income for the quarter, driven by continuing increases in the number of active customers and the average total outstanding principal balance of total on-balance and off-balance loans.

Financial services income increased by 37.1% from RMB778 million in the third quarter of 2017 to RMB1.1 billion in the third quarter of 2018. This increase was primarily contributed by increase in the loan facilitation and servicing fees.

Loan facilitation and servicing fees increased by 404% from RMB80.5 million in the third quarter of 2017 to RMB405 million in the third quarter of 2018. This increase was primarily due to the significant increase in off-balance sheet loans originated as a result of the continuing growth of our business as well as business model adjustments. The Company made some adjustments to the business model of Juzi Licai in the second quarter of 2018. As a result, all new loans funded by individual investors on Juzi Licai under this new business model have been accounted for as off-balance sheet loans, commencing from late April 2018.  Prior to this, loans originated on Juzi Licai were accounted for as on-balance sheet loans. As a result, revenues generated through loan facilitation and servicing increased significantly.

Interest and financial services income decreased by 5.40% from RMB655 million in the third quarter of 2017 to RMB620 million in the third quarter of 2018 due to a decrease in on-balance sheet loans originated on our platform, which was primarily due to the aforementioned business model adjustments in the second quarter. The balances of financing receivables and funding debts on our balance sheets decreased along with less volume of on-balance loans originated on our platform as well as the repayment of existing on-balance sheet loans.

Funding cost decreased by 1.2% from RMB211 million in the third quarter of 2017 to RMB208 million in the third quarter of 2018. This decrease was primarily due to a decrease in our on-balance sheet loans originated on our platform.

Processing and servicing cost increased by 37.4% from RMB60.0 million in the third quarter of 2017 to RMB82.5 million in the third quarter of 2018. This increase was primarily due to an increase in fees to third-party payment platforms, an increase in risk management expenses, and an increase in salaries and personnel related costs.

Provision for credit losses increased by 32.8% from RMB151 million in the third quarter of 2017 to RMB201 million in the third quarter of 2018. We are continuing to improve our credit assessment and risk management capabilities to enhance our collection efforts while maintaining credit risks at a reasonable level.

Gross profit increased by 84.7% from RMB337 million in the third quarter of 2017 to RMB623 million in the third quarter of 2018. The significant increase in the gross profit margin is primarily due to the significant increase of loan facilitation and servicing fees resulting from the increase of proportion of the off-balance loans of our total loans as discussed above, which has higher gross profit margins than interest and financial service income

Sales and marketing expenses increased by 24.9% from RMB108 million in the third quarter of 2017 to RMB134 million in the third quarter of 2018. This increase was primarily due to an increase in share-based compensation expenses allocated to sales and marketing expenses, an increase in payroll expenses, and an increase in online promotional fees and advertising costs.

Research and development expenses increased by 39.6% from RMB67.1 million in the third quarter of 2017 to RMB93.6 million in the third quarter of 2018. This increase was primarily due to an increase in payroll and related expenses, an increase in share-based compensation expenses allocated to research and development expenses, and an increase in depreciation expenses allocated to research and development expenses.

General and administrative expenses increased by 39.0% from RMB52.8 million in the third quarter of 2017 to RMB73.5 million in the third quarter of 2018. This increase was primarily due to an increase in share-based compensation expenses allocated to general and administrative expenses and an increase in payroll expenses. In addition, we incurred an increase in professional service fees and rental expenses.

Gain on guarantee liabilities for the third quarter of 2018 was RMB33.9 million, which was resulted from releasing of liabilities through our performance of the guarantee for loans funded by individual investors on Juzi Licai covered by risk safeguard scheme.

Income tax expense for the third quarter of 2018 was RMB43.1 million, compared to income tax expense of RMB69.3 million in the third quarter of 2017. The decrease of the annualized effective tax rate for the third quarter of 2018 was primarily due to the change of our cost structure and lower enacted tax rate for certain qualified entities.

Net income for the third quarter of 2018 was RMB316 million, representing an increase of 363% from RMB68.2 million in the third quarter of 2017.

Adjusted net income for the third quarter of 2018 was RMB354 million, representing an increase of 213% from RMB113 million in the third quarter of 2017.

Use of Non-GAAP Financial Measures Statement

In evaluating our business, we consider and use adjusted net income and non-GAAP EBIT, two non-GAAP measures, as supplemental measures to review and assess our operating performance. The presentation of the 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 U.S. GAAP. We define adjusted net income as net income excluding share-based compensation expenses, interest expense associated with convertible loans and investment-related impairment and we define non-GAAP EBIT as net income excluding income tax expense/(benefit), share-based compensation expenses, interest expense, net and investment-related impairment.

We present these non-GAAP financial measures because it is used by our management to evaluate our operating performance and formulate business plans. Adjusted net income enables our management to assess our operating results without considering the impact of share-based compensation expenses, interest expense associated with convertible loans and investment-related impairment. Non-GAAP EBIT, on the other hand, enables our management to assess our operating results without considering the impact of income tax expense/(benefit), share-based compensation expenses, interest expense, net and investment-related impairment. We also believe that the use of these non-GAAP financial measures facilitate investors’ assessment of our operating performance. These non-GAAP financial measures are not defined under U.S. GAAP and are not presented in accordance with U.S. GAAP.

These non-GAAP financial measures have limitations as an analytical tool. One of the key limitations of using adjusted net income and non-GAAP EBIT is that they do not reflect all items of income and expense that affect our operations. Share-based compensation expenses, interest expense associated with convertible loans, income tax expense/(benefit), interest expense, net and investment-related impairment have been and may continue to be incurred in our business and are not reflected in the presentation of adjusted net income and non-GAAP EBIT. Further, these non-GAAP financial measures may differ from the non-GAAP financial information used by other companies, including peer companies, and therefore their comparability may be limited.

We compensate for these limitations by reconciling the non-GAAP financial measure to the most directly comparable U.S. GAAP financial measure, which should be considered when evaluating our performance. We encourage you to review our financial information in its entirety and not rely on a single financial measure.
