"We had another successful quarter in which we implemented our strategic plan for growth and diversification while generating positive financial results. Our vehicle conversion kit business, which we began late in the first quarter of 2007, saw another quarter of strong growth, accounting for more than 41% of net revenue in the nine months ending September 30, 2007. We incurred higher operating expenses associated with our CNG filling station businesses and have not generated revenue from this business segment as of September 30, 2007. Despite its current expenses, we view development of our CNG vehicle filling station business as an investment in our future as we seek to become a leader in owning and operating CNG vehicle filling stations in central and east China,” said Mr. Bo Huang, CEO of Sinoenergy Corporation.“We plan to use the proceeds from our recent financing to further our retail CNG vehicle filling station strategy.”

September Quarter 2007 Results

For the quarter ending September 30, 2007, net revenue increased by 83.4% to $7.1 million, from $3.9 million in the comparable quarter in 2006. The increase in net revenue was mainly from the recently started vehicle conversion kit business, which generated $4.0 million, or about 56% of net sales, for the quarter.

Gross profit for the third quarter of 2007 increased 44.6% from the third quarter of 2006 to $3.6 million.

Gross margin in the vehicle conversion kit business was 41.0% in the third quarter of 2007, up from 35.0% in the second quarter of 2007. Overall gross margin declined year-over-year to 50.0% from 64.0% in the third quarter of 2006, mostly because of the effect of the gross margin of the vehicle conversion kit business.

Operating expenses in the third quarter of 2007 were $2.0 million, an increase of 241.6% from $582,000 in the third quarter of 2006. Operating expenses increased in the third quarter because of the increased costs of entering new businesses. Operating expenses included a $689,000 increase in general and administration expenses because of the additional management efforts needed to construct CNG filling stations, and $555,000 of expenses associated with developing the vehicle conversion kit business, and a non-cash charge of $191,000 related to the granting of stock options.

Operating income for the third quarter was $1.6 million, a decrease of 15.7% from $1.9 million in the third quarter of 2006.

Net income was $1.3 million in the quarter ending September 30, 2007, or $ 0.04 per share (basic and diluted), down from net income of $3.3 million, or $0.22 per share (basic and diluted) in the same period in 2006. In the quarter ending September 2006, net income reflected the effect of a 100% enterprise income tax holiday granted to one of the Company’s subsidiaries in that quarter, effective January 1, 2006. As a result, a $1.56 million tax accrual was reversed that was recognized in the quarters prior to the quarter in which the tax holiday was granted.

Results for the Nine Month Period Ending September 30, 2007

Net revenue for the nine months ending September 30, 2007 was approximately $15.9 million, a 64% increase from net revenue of approximately $6.2 million for the nine months ending September 30, 2006. This increase resulted primarily from the sale of vehicle conversion kits, which generated revenue of $6.6 million, or 41.5% of sales in the nine months ending September 30, 2007.

Gross profit for this period was $7.8 million, an increase of 63.7% from $4.8 million in the nine months ending September 30, 2006.

The overall gross margin of 49% for this period was virtually the same as in the same period in 2006. The lack of change in gross margin in the nine months ending September 30, 2007 was the result of lower gross margin for the newly developed CNG conversion kit business being offset by higher gross margin for the pressure containers business, which received two high gross margin specialized orders.

Operating expenses were approximately $3.6 million for the nine month period ending September 2007, an increase of $2.0 million, or 127%, from the nine month period ending September 2006. The increase in operating expenses was mainly the result of about $1.2 million in expenses incurred by the CNG filling station business and $ 0.8 million expenses in newly developed vehicle conversion kits business.

Operating income was $4.2 million, which was up 33.4% from $3.2 million in the nine months ending September 30, 2006.

Net income was $3.6 million, or $0.14 per share (basic and diluted), for the first nine months of 2007 compared to net income of $2.3 million, or $ 0.16 per share (basic and diluted) for the same period in 2006.

Private Placement Financing

On September 28, 2007, Sinoenergy closed on a private placement of 12% Guaranteed Senior Notes in the amount of $16 million and 3.0% Guaranteed Senior Convertible Notes in the amount of $14 million both due in 2012. The Company intends to use the net proceeds of $29.9 million exclusively for the expansion of its CNG wholesale and retail business as well as for potential CNG related acquisitions.

Financial Condition

As of September 30, 2007, cash totaled $4.5million, up from $0.6 million at December 31, 2006. Cash as of September 30, 2007 included $1.2 million of restricted cash, representing a deposit for a bill of exchange in the same amount issued in connection with a purchase of materials by the Company. Working capital as of September 30, 2007 was $24.7 million. Short term liabilities were $25.5 million, and long term liabilities, consisting of the recent financing, were $29.4 million. Stockholders’ equity totaled $32.7, up from $16.0 million as of December 31, 2006. The Company generated $5.2 million in cash flow from operating activities during the nine months ended September 30, 2007.

Outlook

In October 2007, Sinoenergy’s first two retail CNG filling stations were opened in Wuhan, Hubei province. A third retail CNG filling station was opened in Xuancheng, Anhui province in November 2007. As of December 31, 2007, additional ten CNG filling stations were substantially completed which are in the process of obtaining government approvals, and another 20 CNG stations are either under construction or in the construction planning stage. The stations to be opened consist of four stations in Pingdingshan, three stations in Xuancheng and 23 stations in Wuhan. A total of 30 stations are expected to be opened by the end of June 2008.

“We are moving forward with our expansion plans to own and operate wholesale and retail filling stations in eastern and central China. We expect our retail stations to generate meaningful revenue and operating income in fiscal years 2008 and 2009,” said Mr. Tianzhou Deng, Chairman of Sinoenergy. “We also anticipate strong demand for CNG infrastructure products, particularly trailers, and expect continuing demand for our vehicle conversion kits. Our focus in fiscal year 2008 is on continuing growth and improving our mix of higher margin products to improve profitability.”

Given the change in fiscal year end, some delays in municipal government approval for each filling station’s construction and the changes in operating circumstance, the Company has updated its guidance for the fiscal year ended September 30, 2008 for revenue in the range of $53 to $56 million, and operating income in the range of $14 to $15 million. (Previous guidance was for the 2008 calendar year was for revenue in the range of $45 to $47 million and operating income in the range of $13 to 15 million.) For fiscal year 2009, the Company expects revenue in the range of $83 to $85 million and operating income in the range of $24 to $26 million.

Recent Events

On July 2007, Sinoenergy paid $400,000 to increase its ownership from 60% to 70% in Jiaxing Lixun, which designs and sells customized electronic fuel switching conversion kits. Electronic switching conversion kits enable vehicles to use both CNG and alternative fuels such as liquefied petroleum gas.

On August 28, 2007, the Company agreed to acquire the entire equity of Qingdao Jingrun General Machinery Company (“Jingrun”) for approximately $8 million. Jingrun has a workshop and a 644,668 square feet plot of land located in the new development zone of Qingdao City, Shandong province, China. As of September 30, 2007, the Company spent $4,087,175 on this purchase before the actual close of the deal.
