Acorn International Reports Financial Results for the Second Quarter and First Half of 2018

SHANGHAI, Sept. 5, 2018 /PRNewswire/ — Acorn International, Inc. (NYSE: ATV) (“Acorn” or the “Company”), today announced its unaudited financial results for the second quarter and six months ended June 30, 2018.

Second Quarter 2018 Financial and Operational Highlights

In the second quarter of 2018, Acorn achieved solid top line growth due to strong sales of its Babaka posture correction products and Youngleda at-home medical devices via its e-commerce channel. The Company recorded another quarter of improving margins and narrowed its loss from continuing operations to US$0.5 million, approaching breakeven. After successfully completing the sale of non-core assets in May, the Company distributed a special one-time dividend in an aggregate amount of US$40.0 million to its shareholders in June. The Company closed the quarter with a cash position of US$19.5 million, as compared to US$21.1 million at December 31, 2017.

Thus far in 2018, Acorn announced the launch of two new business units: Acorn Fresh, which brings the world’s best fresh and safe food directly to the Chinese consumer, as well as Acorn Entertainment, which provides digital PR to western celebrities and brands to enhance their brand value in China. The Company continually evaluates new business opportunities.

The Company will continue to emphasize the e-commerce channel and is focused on leveraging its 20 years of expertise as a leading direct marketing, infomercial company in China. The Company continually evaluates new platforms with positive ROI conversion, including China’s major e-commerce platforms as well as other niche digital platforms.

Financial Results for the Second Quarter of 2018:

Total net revenues were US$6.3 million in the second quarter of 2018, up 39.4% from US$4.5 million in the second quarter of 2017, primarily due to an increase in e-commerce sales of posture correction products as well as other products.

Cost of sales in the second quarter of 2018 was US$1.8 million, up 28.2% from US$1.4 million in the second quarter of 2017. The increase was attributable to the increased sales volume and net revenues.

Gross profit in the second quarter of 2018 was US$4.5 million, up 44.5% from US$3.1 million in the second quarter of 2017. Gross margin was 71.2% in the second quarter of 2018, up from 68.7% in the second quarter of 2017. The increase in gross margin was due to a larger proportion of higher margin products in the product mix. The Company anticipates gross margins may decline from current levels in the near and medium term as the Company expands its distribution platforms to incorporate additional Chinese e-commerce companies into its e-commerce channel.

Total operating expenses in the second quarter of 2018 were US$5.0 million, down 10.3% from US$5.5 million in the second quarter of 2017. The decrease was primarily due to a decline in general and administrative expenses due to lower professional fees and labor costs, which was partially offset by higher selling and marketing expenses to support e-commerce sales. Operating expenses included non-cash, share-based compensation of US$108,645 in the second quarter of 2018. There was no share-based compensation in the second quarter of 2017.

Loss from continuing operations was US$0.5 million in the second quarter of 2018, as compared to loss from continuing operations of US$2.4 million in the second quarter of 2017.

As of June 30, 2018, after payment of a special cash dividend of approximately US$40 million, Acorn’s cash and cash equivalents, with restricted cash, totaled US$19.5 million. Cash and equivalents, with restricted cash, totaled US$21.1 million as of December 31, 2017.

At June 30, 2018, the Company owned 32,723,600 shares of Yimeng Software Technology Co., Ltd. (“Yimeng”), a publicly traded company in China valued at approximately US$43.9 million based on the stock price at December 31, 2017. The Company may sell shares of Yimeng from time to time based on market factors and its other investment and capital requirements.

During the first half of 2018, the Company repurchased 1,860 ADSs at an average price US$20.44 per ADS under its share repurchase program, which was approved by the Board of Directors on December 8, 2017.

Discontinued Operations

In 2017, Acorn reached an agreement to sell a majority stake in its HJX electronic learning products business (“HJX Business”) to a third-party investor and operator, allowing the Company to focus on businesses and brands with higher profit margins, and on achieving profitable growth of new, potentially high margin businesses. Acorn retained a 37.5% stake in a joint venture established with this third party. As a result of this transaction, the Company is required by applicable accounting rules to treat the HJX Business as discontinued operations in the consolidated statements of operations for all periods presented.
