Recent Business Highlights

· On June 8, 2011, the Company announced that it signed a Letter of Intent with EarthSearch Communications International, Inc. (“EarthSearch”), a subsidiary of East Coast Diversified Corporation (OTC.BB: ECDC.ob) as the basis for further discussion regarding the terms and conditions that may apply in a formal agreement to be executed between both parties in the future.  Under any such formal agreement, ZST Digital would be granted Chinese distribution and marketing rights to EarthSearch’s Logiboxx product, a proprietary technology for integrated wireless communication between GPS and RFID, and ZST would provide technical and administrative support for the product in China.

· On June 20, 2011, the Company announced that it filed a patent application with the Chinese State Intellectual Property Office (SIPO) to ensure intellectual property protection for its Assisted GPS technology.Assisted GPS, or A-GPS, is a technology used to improve the performance of traditional standalone GPS tracking systems which rely solely on radio signals from satellites and can be impacted by poor signal conditions in certain environments, for example in dense urban areas. Without requiring any additional hardware, ZST Digital’s A-GPS system can make use of the GSM modules and location based service (LBS) capabilities of customers’ existing mobile phone equipment, in conjunction with additional software, to introduce LBS capabilities to the GPS system, forming a dual-positioning mode.

· On July 12, 2011, the Company reported that Chairman and Chief Executive Officer Mr. Zhong Bo was named a “Zhengzhou City Outstanding Entrepreneur” in a ceremony held by the Zhengzhou Association of Enterprises and the Zhengzhou Entrepreneurs Association.

Mr. Zhong Bo, Chairman and Chief Executive Officer of ZST, commented, “We delivered another quarter of healthy top- and bottom-line growth supported by strong sales  of our commercial GPS fleet management products and services and continued expansion of our cable TV related businesses.  Sales revenue from our IPTV, cable TV network equipment and commercial GPS fleet management tracking segments accounted for approximately 39%, 32% and 29% of total revenues, respectively.     We continue to benefit from government regulations which are spurring demand within our end markets, especially for commercial GPS fleet management products and services.  We expect these positive trends to continue to support the growth of our commercial GPS-related business segment in the second half of the year, and we remain confident in our ability to reach our full year guidance.  As we enter the second half, we will continue to focus on delivering profitable growth, maintaining the highest standards of transparency and disclosure and increasing shareholder value.”

Mr. Henry Ngan, Chief Financial Officer of ZST, commented, “We delivered a strong financial performance in the second quarter with year-over-year revenue increases across all three of our product segments.   We believe that the underlying demand for our products and services remains healthy, and we are especially pleased with the rapid growth of our commercial GPS segment.  While gross profit margin declined slightly in the quarter due to the change in sales mix of our IPTV products, we nevertheless maintained a healthy profit margin level thanks to the high-margin profile of our commercial GPS products and services.  We further strengthened our balance sheet in the second quarter, and we believe that we are well-positioned to fund our continued growth.  We enter the second half of the year on a strong footing and maintain our commitment to increasing long-term shareholder value.”

Second Quarter 2011 (unaudited) Financial Highlights

Revenue

Revenue for the second quarter of 2011 was US$41.4 million, representing an increase of 25% from US$33.0 million in the second quarter of 2010. The primary reason for the increase in revenue during the quarter was strong growth in the commercial GPS-related business line.  Revenue from sales of GPS devices and related service amounted to $12.1 million, representing an increase of 102% year-over-year, supported by the growing market demand for commercial GPS fleet management systems in response to government regulations requiring the registration of certain types of commercial vehicles on GPS platforms for government monitoring purposes.  For the second quarter, the cable TV-related business and the commercial GPS-related business accounted for approximately 71% and 29% of total revenue, respectively, compared to 82% and 18% for the comparable period in 2010.

Gross Profit and Gross Profit Margin

Gross profit for the second quarter of 2011 was US$10.2 million, representing a 24% year-over-year increase. Gross profit margin for the second quarter of 2011 was 24.7%, essentially flat compared to 25% in the second quarter of 2010.

Operating Expenses

Total operating expenses for the second quarter of 2011 were US$1.4 million, representing an increase of 39% from US$1.0 million in the second quarter of 2010. This increase in operating expenses was primarily a result of the higher volume of business activities generated.

Selling expenses for the second quarter 2011 were US$203,000, an increase of 86% from US$109,000 for the second quarter of 2010.  Selling expenses comprise mainly salaries, shipping costs, and after-sale service expenses.  Since our suppliers cover most of the shipping costs, we have not incurred high selling expense relative to our substantial increase in revenue.  As a percentage of total revenue, selling expenses accounted for 0.5% and 0.3% for the second quarter of 2011 and 2010, respectively.

Research and development expenses (R&D) for the second quarter 2011 were US$167, 000, an increase of 76% compared to US$95,000 for the second quarter of 2010. The increase resulted from the continued focus on the commercial GPS tracking business as we continued to expand the overall scope of the segment. As a percentage to total revenue, R&D expense accounted for 0.4% and 0.3% for the second quarter of 2011 and 2010, respectively.

General and administrative expenses (G&A) for the second quarter 2011 were US$1.1 million, up 28% from US$0.8 million in the second quarter of 2010. The rise in G&A expenses was mainly attributable to an increase in salary expenses and stock-based compensation.  As a percentage to total revenue, G&A expenses accounted for 2.6% and 2.5% for the second quarter of 2011 and 2010, respectively.

Income from Operations

Income from operations was US$8.8 million in the second quarter of 2011 representing an increase of 22% compared to operating income of US$7.2 million in the second quarter of 2010.

Income Tax

Income tax expense for the second quarter of 2011 was US$2.5 million, compared to approximately US$2.0 million in the second quarter of 2010. This increase was mainly due to an increase in taxable income.

Net Income and EPS

Net income for the second quarter of 2011 was US$6.4 million, a year-over-year increase of 22% from US$5.2 million in the second quarter of 2010. Net margin was 15.4% for the second quarter of 2011 compared to 15.7% in the second quarter of 2010.

Diluted net income per share was US$0.55 in the second quarter 2011, compared to US$0.45 for the second quarter of 2010, based on weighted-average common shares outstanding of 11,613,730 and 11,650,442, respectively.

Balance Sheet

Cash and cash equivalents totaled to US$50.2 million as of June 30, 2011, compared to US$40.2 million as of March 31, 2011, primarily attributable to cash generated from operations.

As of June 30, 2011, total accounts receivables were US$27.8 million, an increase of 31% from US$21.3 million as of March 31, 2011, primarily due to a higher volume of business generated.

Full Year 2011 Outlook – For the full year 2011, the Company reiterates its estimates that revenues will range between US$160 million and US$175 million, and net income will range between US$28 million and US$30 million. This represents the Company’s current and preliminary view, which is subject to change.
