“It was an excellent quarter both from capital market and company perspectives. The equity markets garnered momentum during the quarter, with China A shares rising over 30%, delivering its highest increase in the past three years, and the S&P 500 posting its best first quarter since 1998. Investors’ engagement in our securities services was enthusiastic under this bullish market. Benefiting from the market rally and our ability to capitalize on the market opportunities our asset management team delivered outstanding gains and contributed significantly to the financial results. Both factors drove our record revenues of RMB 454.3 million, up 69% year-over-year and 54% sequentially and strong profitability as well for the first time since we transited to a comprehensive financial service provider beginning in the second half of 2017. The strength of these results more than offset the slight decline in commodity trading revenues,” said Mr. Wenbin Chen, Chairman and CEO of Yintech.

“In the first quarter, our asset management business not only delivered outstanding results to both topline and bottom-line growth, but also received industry recognitions thanks to its remarkable performance. In total, we have received 13 high rankings in competitions for the first quarter. For the first two months of 2019 our asset management company ranked No.5 of the ‘Top 10 Equity-Oriented Private Equity Companies’ among over 10,000 peers in China and the ranking was further lifted to No.3 for the first three month period. Our convertible securities funds also delivered outstanding performance, one of which was rated No.6 in February and remained Top 10 in the first quarter out of 1,500 competitors. On average our equity funds and convertible bond products largely outperformed SCI 300 index and other major comparable indexes. We see this recognition as an affirmation of our emphasis on professionalism, value, service, and trust as we attract and support a growing share of China investable wealth. We believe our investment insights and skills will continue to contribute to our financial performance as well as business growth in the mid-to-long run.”

“Under the mission of leveraging our expertise, technology, and people to bring greater ease, knowledge, fun and accessibility to investment and trading to investors, we remain steadfast in our ‘Client First’ approach to diligently seeking to offer accessible value-add products and services that provide investors with greater choices and values. Our Fintech innovation lab rounded out our value-add services continuum in the first quarter with the completion of ‘Intelligent Investor’- compelling stock screening software, focusing on finding undervalued stock against its intrinsic value. Additionally, our advanced technology efforts, such as ‘Stock Profiling’, a 360 degree stock analysis application targeting A share, Hong Kong and US stocks, are gaining traction with clients and we will continue to expand the ways in which our clients can interact with us online, bringing more enjoyment and ultimately more gains to clients and the company.”

“At the same time, we’re expected to see benefits of our successful acquisition of Type 2 and Type 5 regulatory licenses from the Hong Kong Securities and Futures Commission, which permitted Forthright Securities to deal in futures and advise on futures contracts. In securing these licenses, our clients can trade multiple asset classes including securities and futures trading and continue to rely on our leading technology and trading expertise combined with specialist in-depth insight into the securities and futures industry, which is an important component of our value proposition.”

First Quarter 2019 Financial Results

Revenues for the quarter were RMB454.3 million (US$67.7 million), compared with RMB268.5 million for the same quarter last year and RMB295.2 million for the previous quarter. The year-over-year and sequential increases were mainly attributable to increase in net commissions and fees from securities services as well as trading gains generated from our asset management business.

Net commissions and fees for the quarter were RMB246.5 million (US$36.7 million), representing an increase of 1.6% year-over-year and a decrease of 9.8% sequentially. The year-over-year increase was primarily due to the increase in securities services partially offset by the decrease in commodities services. The sequential decrease was mainly resulted from lower trading volume of commodities from the previous quarter.

Net commissions and fees from commodities services for the quarter were RMB123.7 million (US$18.4 million), a decrease of 18.9% from the previous quarter, primarily as a result of decrease in customer trading volume for futures commodities.

Customer trading volume for commodities (representing customer trading volume of spot and futures commodities) was RMB315.3 billion (US$47.0 billion) during the quarter, a decrease of 36.9% year-over-year and 23.8% from the previous quarter primarily due to low volatility of gold in the first quarter.

Effective fee rate for commodities (representing net commissions and fees from commodities services as a percentage of customer trading volume for commodities) for the quarter was 0.039%, compared with 0.040% in the same quarter last year and 0.037% in the previous quarter.

Net commissions and fees from securities services for the quarter were RMB122.8 million (US$18.3 million), an increase of 172.3% year-over-year and 1.6% from the previous quarter, primarily due to growth of overseas brokerage services in more favorable market conditions relative to the previous quarter. The robust growth demonstrates the effectiveness of the Company’s strategy to expand its securities business and its ability to execute.

Expenses for the quarter were RMB306.4million (US$45.7 million), a decrease of 0.9% from RMB309.1 million in the same quarter last year and a decrease of 70.6% from RMB1,041.2 million in the previous quarter. The sequential decrease was mainly attributable to a non-cash impairment charges of RMB639.0 million recognized in the fourth quarter of 2018.

Net income for the quarter was RMB75.1 million (US$11.2 million), compared with net loss of RMB63.1 million in the same quarter last year and net loss of RMB732.2 million in the previous quarter.

Net income attributable to Yintech for the quarter was RMB69.2 million (US$10.3 million), compared with net loss of RMB50.3 million in the same quarter last year and net loss of RMB727.7 million in the previous quarter.

Diluted earnings per ADS for the quarter was RMB0.92 (US$0.14), compared with diluted loss per ADS of RMB0.71 in the same quarter last year and diluted loss per ADS of RMB10.39 in the previous quarter.

Non-GAAP net income attributable to Yintech for the quarter was RMB85.6 million (US$12.8 million), compared with net loss of RMB29.1 million in the same quarter last year and net loss of RMB106.8 million in the previous quarter.

Non-GAAP diluted earnings per ADS for the quarter was RMB1.14 (US$0.17), compared with non-GAAP diluted loss per ADS of RMB0.41 in the same quarter last year and non-GAAP diluted loss per ADS of RMB1.52 in the previous quarter.

As of March 31, 2019, the Company had RMB1,753.2 million (US$261.2 million) in cash and short term investments, compared with RMB1,736.9 million as of December 31, 2018.

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 March 31, 2019, the Company had purchased an aggregate of 938,410 ADSs.

On May 30, 2019, Yintech’s board of directors approved a share repurchase program (“2019-2020 Share Repurchase Program”), effective on June 2, 2019, which authorizes the Company to repurchase up to US$20 million worth of its issued and outstanding American Depositary Shares over the course of 12 months.

The share repurchase program will be funded with Yintech’s available cash balance. As of March 31, 2019, Yintech had cash and short term investments of approximately RMB1,753.2 million (US$261.2 million).

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 impairment and amortization of intangible assets and/or goodwill 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 as 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 impairment and amortization of intangible assets and/or goodwill 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.
