Futu Announces Second Quarter 2019 Unaudited Financial Results

HONG KONG, August 26, 2019 (GLOBE NEWSWIRE) — Futu Holdings Limited (“Futu” or the “Company”) (NASDAQ: FHL), a leading tech-driven online brokerage platform in China, today announced its unaudited financial results for the second quarter ended June 30, 2019.

Second Quarter 2019 Operational Highlights

Second Quarter 2019 Financial Highlights

“We are pleased to report solid performance in the second quarter of 2019, despite ongoing market volatility,” said Mr. Leaf Hua Li, Futu’s Chairman and Chief Executive Officer. “Our superior technology infrastructure has always been a major source of our competitive advantage. In June, we became the first Chinese broker to offer full market-depth for US option quotes, with quote refresh rates that are much faster than our peers in the region. Our technological capabilities continue to redefine traditional investing for individual investors who we believe deserve a best-in-class trading experience.”

“Our growth outside of mainland China remains strong. In the second quarter of 2019, the number of paying clients in Hong Kong rose 115% year-over-year as we continue to enhance our brand awareness and our new wealth management products gain traction in the region. In May, we officially launched Money Plus, a money market mutual fund distribution platform, in Hong Kong, which marks our initial foray into the wealth management business. Since the end of the second quarter, we have already started to offer a number of fixed income and equity funds, and we plan to distribute more financial products on our platform in the quarters to come.”

“In May, we launched our new enterprise service brand, I&E, to integrate our IPO subscription and ESOP solution services. As of June 30, 2019, we had 39 ESOP clients, and among the 11 new additions in the second quarter were Douyu, the recently-IPO’d game-streaming business, and a number of other leading Chinese new economy companies. We continue to see good synergies between our retail business and enterprise service business, which serves as an important client acquisition channel.”

Mr. Arthur Yu Chen, Futu’s Chief Financial Officer, said, “We were able to maintain our strong growth momentum in the second quarter. The total number of paying clients increased 50.5% year-over-year to over 164 thousand. We think it is particularly encouraging that as our paying clients continued to grow, our quarterly client retention rate also reached a stunning 98.1%, which is a new high since 2018.”

“Overall, our revenue and gross profit reached HK$259.9 million and HK$196.1 million, representing increases of 39.6% and 55.9%, respectively, from the same period in 2018. As we scale our business, our gross margin also rose to 75.5% from 67.6% in the second quarter of 2018. We will continue to invest in technology to sustain our competitive advantages and market our business as we expand globally. We remain confident in our ability to solidify our leading position in the market.”

Second Quarter 2019 Financial Results

Revenues

Total revenues were HK$259.9 million (US$33.3 million), an increase of 39.6% from HK$186.2 million in the second quarter of 2018.

Brokerage commission and handling charge income was HK$122.3 million (US$15.7 million), an increase of 35.7% from HK$90.1 million in the second quarter of 2018. The increase was mainly attributable to a rise in trading volume in the U.S. market as well as the growth in effective fee rates.

Interest income was HK$113.9 million (US$14.6 million), an increase of 30.8% from HK$87.1 million in the second quarter of 2018. The rise was primarily due to 1) the increase in the balance of client deposits and the improved return on the balance due to enhanced capital management and higher benchmark interest rates in the U.S. and Hong Kong; 2) the growth of the Company’s U.S. margin financing business.

Other income was HK$23.6 million (US$3.0 million), an increase of 159.3% from HK$9.1 million in the second quarter of 2018. The rise was primarily due to the increase of underwriting fee income and enterprise public relations service charge income.

Costs

Total costs were HK$63.8 million (US$8.2 million), an increase of 5.6% from HK$60.4 million in the second quarter of 2018.

Brokerage commission and handling charge expenses were HK$24.3 million (US$3.1 million), an increase of 20.9% from HK$20.1 million in the second quarter of 2018. The rise was primarily due to the increase in trading volume, which was in line with the Company’s brokerage commission income.

Interest expenses were HK$18.8 million (US$2.4 million), a decrease of 21.3% from HK$23.9 million in the same period of 2018. The decrease was primarily because the Company had fully repaid funds borrowed from other parties by the end of the first quarter of 2019.

Processing and servicing costs were HK$20.7 million (US$2.6 million), an increase of 25.5% from HK$16.5 million in the second quarter of 2018. The rise was primarily due to the increase in both market information and data fees and cloud service fees as the Company continued to expand market data service and enhance infrastructure.

Gross Profit

Total gross profit was HK$196.1 million (US$25.1 million), an increase of 55.9% from HK$125.8 million in the second quarter of 2018.

Gross margin was 75.5%, compared with 67.6% in the second quarter of 2018. The rise was primarily due to greater operating leverage as a result of the Company’s larger scale and improved operating efficiency.

Operating Expenses

Total operating expenses were HK$144.9 million (US$18.6 million), an increase of 66.6% from HK$87.0 million in the second quarter of 2018.

Research and development expenses were HK$63.7 million (US$8.2 million), an increase of 82.5% from HK$34.9 million in the second quarter of 2018. The rise was primarily due to the continued increase in research and development headcount to support the Company’s business growth.

Selling and marketing expenses were HK$42.3 million (US$5.4 million), an increase of 45.9% from HK$29.0 million in the second quarter of 2018. The rise was primarily due to higher branding and marketing spending in the second quarter of 2019.

General and administrative expenses were HK$38.9 million (US$5.0 million), an increase of 67.7% from HK$23.2 million in the second quarter of 2018. The rise was primarily due to an increase in headcount for general and administrative personnel.

Net Income

Net income increased by 128.5% to HK$55.3 million (US$7.1 million) from HK$24.2 million in the second quarter of 2018. The rise was primarily due to strong topline growth and local tax rebates in relation to prior R&D expenses.

Non-GAAP adjusted net income increased 121.7% to HK$59.2 million (US$7.6 million) from HK$26.7 million in the corresponding period of 2018. Non-GAAP adjusted net income is defined as net income excluding share-based compensation expenses. For further information, see “Use of Non-GAAP Financial Measures” at the bottom of this press release.

Net Income per ADS

Basic net income per American Depositary Share (“ADS”) was HK$0.50 (US$0.06), compared with HK$0.08 in the second quarter of 2018. Diluted net income per ADS was HK$0.44 (US$0.06), compared with HK$0.08 in the second quarter of 2018. The rise was primarily due to higher net income and the conversion of preferred shares to ordinary shares. Each ADS represents eight Class A ordinary shares.

Use of Non-GAAP Financial Measures

In evaluating the business, the Company considers and uses non-GAAP adjusted net income, a non-GAAP measure, as a supplemental measure to review and assess its operating performance. The presentation of the non-GAAP financial measure 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. The Company defines non-GAAP adjusted net income as net income excluding share-based compensation expenses. The Company presents the non-GAAP financial measure because it is used by the management to evaluate the operating performance and formulate business plans. Non-GAAP adjusted net income enables the management to assess the Company’s operating results without considering the impact of share-based compensation expenses, which are non-cash charges. The Company also believes that the use of the non-GAAP measure facilitates investors’ assessment of its operating performance.

Non-GAAP adjusted net income is not defined under U.S. GAAP and is not presented in accordance with U.S. GAAP. This non-GAAP financial measure has limitations as analytical tools. One of the key limitations of using non-GAAP adjusted net income is that it does not reflect all items of expense that affect the Company’s operations. Share-based compensation expenses have been and may continue to be incurred in the business and is not reflected in the presentation of non-GAAP adjusted net income. Further, the non-GAAP measure may differ from the non-GAAP information used by other companies, including peer companies, and therefore their comparability may be limited.

The Company compensates for these limitations by reconciling the non-GAAP financial measure to the nearest U.S. GAAP performance measure, all of which should be considered when evaluating the Company’s performance.

For more information on this non-GAAP financial measure, please see the table captioned “Unaudited Reconciliations of Non-GAAP and GAAP Results” set forth at the end of this press release.
