Increase of 18.6% for the Fiscal First Half of 2019

WENZHOU, China, September 17, 2019 -- ZK International Group Co., Ltd. (ZKIN) ("ZK International" or the "Company"), a designer, engineer, manufacturer, and supplier of patented high-performance stainless steel and carbon steel pipe products primarily used for water and gas supplies, today announced its unaudited financial results for the six months ended March 31, 2019.

Financial Highlights for the six months ended March 31, 2019

Mr. Jiancong Huang, Chairman and Chief Executive Officer of ZK International, commented, "Our first half of fiscal year 2019 results reflected the continued strength in sales volume partially offset by decreased weighted average selling prices (“ASP”) for our products and the depreciation of RMB against US$. As measured in RMB, revenue increased by 23.06% year-over-year to RMB215.4 million despite decrease in blended ASP.”

Mr. Huang continued, "Despite continuing headwinds with challenging pricing environment and depreciation of RMB against US Dollar during the second half of fiscal year 2019, our orders book remains strong and we expect it to continue to drive double digits growth in both sales volume and revenue in the second half of fiscal year 2019 as we continue to expand our product portfolio, build our brands and cultivate new customer relations”.

Financial Results for the Six Months Ended March 31, 2019

Revenue

For the six months ended March 31, 2019, revenue increased by $4.94 million, or 18.6%, to $31.54 million from $26.60 million for the same period of the last fiscal year. The increase in revenue is primarily attributable to the increased sales volume of stainless steel coil products, partially offset by 5.4% depreciation of RMB against US$. As measured in RMB, revenue increased by 23.06% year-over-year to RMB215.4 million, thanks to continued growth in overall sales volume that more than offset the decrease in blended ASP as prices for steel strips and coils dropped during six months ended March 31, 2019.

Gross Profit

Gross profit decreased by $0.55 million, or 6.4%, to $8.08 million for the six months ended March 31, 2019 from $8.63 million for the same period of last fiscal year. As a result, gross margin decreased by 6.82 points to 25.6% for the six months ended March 31, 2019 from 32.4% for the same period of last fiscal year. The decrease in gross margin was primarily due to decreased percentage of sales from higher margin, premium pipe products versus increased percentage of sales from lower margin stainless steel coil products.
