Mr. Jiancong Huang,Chairman of ZK International,commented,"During the fiscal first six months of 2018 we focused on growth and investment. We have not only successfully increased our manufacturing capacity,but also significantly bolstered our sales and marketing capabilities. In doing so,we increased top and bottom line approximately 29% year-over-year,largely driven by new contracts,growth internationally,and new service offerings. Our increased capacity has allowed the Company to meet the demand of the Chinese government to implement mandatory standards for water and gas infrastructure improvements."

Mr. Huang continued,"As we continue to build our brand and cultivate new customer relationships,it is equally important that we remain forward thinkers and innovators. Our investment in research and development has yielded our company the opportunity to one day introduce the Intelligent Piping System to the market which combines revolutionary new aspects to our industry such as the remote water testing sensors and blockchain-based information distribution system. We will continue to invest in ourselves for not only growth today,but for years to come."

Operational Highlights for Fiscal First Half of 2018:

Strategically focused on providing premium pipeline products and engineering and design solutions to water and gas pipe infrastructure sector that has seen increasing governmental investment to supply clean water and safe gas through stainless steel and carbon steel pipe network to accommodate fast paced urbanization of China. As a result of the market trend and sales network expansion,the revenue generated from sale of pipeline products and engineering and design solutions,which yields higher gross profit than the stainless steel coil business line,increased from 66.7% to 88.4% as a percentage of sales and thus gross profit margin increased from 29% to 32.4%.

Expanded business operations into the emerging multi-billion dollar metal pipe market located in Africa,initially targeting Uganda,one of the leading countries in East Africa,for its growth in the Oil and Gas sectors. ZK International is looking to expand its business operations in Uganda as it eyes the Ugandan government's oil and gas initiative to build a 1,445 KM pipeline from Lake Albert in Uganda to the Port of Tanga in Tanzania.

ZK International and its subsidiary,xSigma Corporation,have begun the implementation of its patent pending software and blockchain technologies into its manufacturing process and supply chain management system. In addition,the two companies are working together to develop remote water testing system that can test the quality of water that flows through the Company's pipe using water testing sensors.

Increased sales force in retail piping division from 15 to 49 professionals in 37 cities and 16 provinces,which have allowed the Company to sell products directly to the interior design firms and home owners and build new customer relationships.

Significant Contracts in Fiscal First Half of 2018:

Selected as a major supplier during the annual bid with Changsha Water Group to supply stainless steel piping for the water supply infrastructure of Changsha,the capital and most populous city in Hunan Province. In November 2017,the municipal government of Changsha issued a regulation to immediately begin updating the existing water supply infrastructure pipeline to stainless steel.

After a 400% increase in orders year-over-year,ZK International renewed its contract with Towngas China Company Limited ("Towngas China"),one of the largest public utility providers in China and one of the largest suppliers of gas in Asia.

Signed agreement with Shenzhen Water Group Co.,Ltd. in the amount of $3.0 million to deploy the Company's proprietary stainless steel pipes and fittings through the city's Community Pipeline Network Upgrade Program.

Entered into $1.2 million contract with The XingRong Group,one of the largest water treatment and supply companies in Western China,to supply approximately 280,000 meters of piping and 280,000 pipe fittings over the course of one year.

Financial Results for the Fiscal Six Months Ended March 31,2018:

For the fiscal first half of 2018,revenue increased by 29.2% to $26.6 million as compared to $20.6 million during the fiscal first half of 2017. The increase in revenue is primarily attributable to the increase in capital expenditure by the government in China to build healthier and safer clean water supply infrastructure in urban areas. Additionally,the Company increased international sales in China by 61.5% during the fiscal first half of 2018 as compared to the same period in 2017.

Gross profit for the fiscal first half of 2018 increased 44.6% to $8.6 million as compared to $5.9 million during the fiscal first half of 2017. Gross profit margin increased to 32.4% for the fiscal first half of 2018 as compared to 29% for the fiscal first half of 2017. Gross profit margin increased primarily due to an increase in the Company's sales of premium pipeline products and engineering and design solutions for client construction projects,which yield higher gross margin,increased from 66.7% to 88.4% as a percentage of sales year-over-year. During the fiscal first half of 2018 lower margin stainless steel coil product sales decreased from 33.3% to 11.6% as a percentage of sales year-over-year.

Operating expenses increased 82.8% year-over-year to $3.7 million as compared to $2.1 million year-over-year. The increase is mainly due to an increase in selling and marketing expense. The increase reflected higher Selling and Marketing Expenses related to the sales growth,increased general and administrative expenses ("G&A") and higher research and development ("R&D") costs. During the period,the Company increased its sales force by 227% from 15 to 49 professionals in 37 cities and 16 provinces throughout China to strategically target the consumer plumbing market. As a percentage of revenue,operating expenses were 14.1% in the fiscal first half of 2018,compared with 9.9% in the fiscal first half of 2017.

Income from operations increased 24.6% to $4.8 million in the fiscal first half of 2018 as compared with $3.9 million in the fiscal first half of 2017. As a percentage of revenue,income from operations was 18.3% during the fiscal first half of 2018 as compared to 18.9% in the 2017 for the same period the year prior.

Net income attributable to ZK International for the fiscal first half of 2018 totaled $3.6 million as compared to $2.9 million in the fiscal first half of 2017. Earnings per share for the fiscal first half of 2018 was $0.29,841 shares total outstanding as of the fiscal period.

Comprehensive net income attributable to ZK International for the fiscal first half of 2018 increased 80.04% to $3.8 million as compared with $2.1 million in the fiscal first half of 2017. The increase was mainly due to the increase of net income and appreciation of Chinese Yuan against US Dollar which led to comprehensive gain on currency translation.
