Mr. Wenbin Chen, Chairman and CEO of Yintech, commented, “Throughout the first nine months of this year we experienced increased macro-economic and capital markets volatility. During the third quarter, the major A-share indexes continued to face strong headwinds, significantly impacting investor sentiment beyond our initial expectations. As a result, lower trading volumes negatively affected our growth, in particular, our securities advisory and investor education services. At the same time, our commodities services business also continued to face unfavorable market conditions, as we previously anticipated. The volatility in the spot price of gold T+D hit another record low during the quarter, further reducing investors’ trading activity. Overall, the decline in gold T+D trading volume was in line with lower trading volumes on the Shanghai Gold Exchange.”

“Despite a challenging market environment, we still generated moderate top line growth sequentially, and improvements in operating efficiency and cost controls positively impacted our bottom line. Since the beginning of this year, we have posted narrower quarterly losses on a sequential basis. Net loss declined 23% sequentially in the third quarter following a 30% decline in the second quarter from the first.”

“Looking ahead, we remain fully committed to investing in client education, enhancing our professional capabilities, introducing more innovative new products and value-added services, as well as investing in new business initiatives to better serve our premium customers. We are realigning our resources with a focus on these key areas as part of our continuous efforts to streamline our business and position our company for rapid growth when market sentiment improves and investors become more active again.”

Third Quarter 2018 Financial Results

Revenues for the quarter were RMB267.8 million (US$39.0 million), compared with RMB388.3 million in the same quarter last year and RMB263.3 million in the previous quarter. Both year-over-year and sequential decreases were mainly due to a decrease in commissions and fees from spot commodities services, which were partially offset by an increase in net commissions and fees from securities services.

Net commissions and fees for the quarter were RMB208.0 million (US$30.3 million), compared with RMB337.9 million in the same quarter last year and RMB217.9 million in the previous quarter, primarily due to the reasons stated above.

Net commissions and fees from commodities services for the quarter were RMB123.8 million (US$18.0 million), a decrease of 5.1% from the previous quarter, primarily as a result of a decrease in customer trading volume for commodities. Customer trading volume for commodities was RMB403.2 billion (US$58.7 billion) during the quarter, a decrease of 0.6% from the previous quarter.

Net commissions and fees from securities services for the quarter were RMB84.2 million (US$12.3 million), a decrease of 3.7% from the previous quarter, primarily due to negative market conditions.

Effective fee rate (representing net commissions and fees from commodities services as a percentage of customer trading volume) for the quarter was 0.031%, compared with 0.04% in the same quarter last year and 0.032% in the previous quarter.

Expenses for the quarter were RMB302.1 million (US$44.0 million), a decrease of 4.2% from RMB315.3 million in the same quarter last year and a decrease of 4.0% from RMB314.6 million in the previous quarter. The year-over-year and sequential decreases were mainly due to cost control measures implemented on advertising and promotion expenses.

Net loss for the quarter was RMB33.9 million (US$4.9 million), compared with net income of RMB66.5 million in the same quarter last year and net loss of RMB44.2 million in the previous quarter.

Net loss attributable to Yintech for the quarter was RMB36.6 million (US$5.3 million), compared with net income of RMB68.6 million in the same quarter last year and net loss of RMB48.5 million in the previous quarter.

Diluted loss per ADS for the quarter was RMB0.50 (US$0.07), compared with diluted earnings per ADS of RMB0.94 in the same quarter last year and diluted loss per ADS of RMB0.64 in the previous quarter.

Non-GAAP net loss attributable to Yintech for the quarter was RMB22.3 million (US$3.2 million), compared with net income of RMB101.0 million in the same quarter last year and net loss of RMB31.0 million in the previous quarter.

Non-GAAP diluted loss per ADS for the quarter was RMB0.31 (US$0.05), compared with non-GAAP diluted earnings per ADS of RMB1.38 in the same quarter last year and non-GAAP diluted loss per ADS of RMB0.41 in the previous quarter.

As of September 30, 2018, the Company had cash of RMB210.3 million (US$30.6 million) and short-term investments of RMB1,599.4 million (US$232.9 million), compared with RMB381.6 million and RMB1,309.6 million as of June 30, 2018, respectively.

As of September 30, 2018, total shareholders’ equity was RMB3,362.5 million (US$489.6 million), compared with RMB3,385.3 million as of June 30, 2018.

2018 Fourth Quarter Guidance

· Revenues will be in the range of RMB280.0 million to RMB300.0 million.

Share Repurchase Program

On May 29, 2018, the Company announced a share repurchase program whereby Yintech is authorized to repurchase up to US$30 million of its issued and outstanding ADSs during the following 12-month period. As of September 30, 2018, the Company had purchased an aggregate of 523,377 ADSs.

Discussion of Non-GAAP Financial Measures

In addition to disclosing financial results prepared in accordance with U.S. GAAP, the Company’s earnings release contains non-GAAP financial measures that exclude the effects of all forms of share-based compensation, as well as amortization of intangible assets in relation to the acquisition of Gold Master. The reconciliation of these non-GAAP financial measures to the nearest GAAP measures is set forth in the table captioned “Reconciliation of GAAP to Non-GAAP Results” below.

The non-GAAP financial measures disclosed by the Company should not be considered a substitute for financial measures prepared in accordance with U.S. GAAP. The financial results reported in accordance with U.S. GAAP and reconciliation of GAAP to non-GAAP results should be carefully evaluated. The non-GAAP financial measure used by the Company may be prepared differently from, and therefore may not be comparable to, similarly titled measures used by other companies.

When evaluating the Company’s operating performance in the periods presented, management reviewed the non-GAAP net income and non-GAAP EPS results reflecting adjustments to exclude the impact of share-based compensation as well as amortization of intangible assets in relation to the acquisition of Gold Master to supplement U.S. GAAP financial data. As such, the Company believes that the presentation of the non-GAAP net income and the diluted non-GAAP income per ADS provides important supplemental information to investors regarding financial and business trends relating to the Company’s financial condition and results of operations in a manner consistent with that used by management. Pursuant to U.S. GAAP, the Company recognized significant amounts of expenses for the restricted shares and share options, as well as amortization of intangible assets in relation to the acquisition of Gold Master in the periods presented. The Company utilized the non-GAAP financial results to make financial results comparable period to period and to better understand its historical business operations.
