Factors for the Decline While the company posted strong revenue growth (+37.2% sequentially) in their Q2 17 earnings report, issues of increased supply chain pricing negatively impacting their cost structure. Further, these costs look like they are going to continue to increase into 2018. Lastly, the increased pricing coupled with more shipments from lower margin products caused gross margins to come in below expectations. Management’s Take According to Mr. Kangping Chen, CEO, “ Shipments over the past few quarters have surged to new highs, allowing us to continuously capitalize on the growing recognition of JinkoSolar's brand and excellent products and services to increase our market share. While ASPs declined during the quarter, prices along our supply chain remained relatively high and impacting our margins. We also worked with our OEM partners more extensively than expected during the quarter to ensure timely delivery, which adversely impacted our margins. We are currently reviewing our strategy in order to improve profitability and further cut down the use of OEM going forward. Our efforts will also be focused on strengthening inventory management and controlling operating expenses.” Price and Earnings Consensus Graph As you can see in the graph below the stock price had a nice run, but higher than expected supply chain pricing, and lower gross margins have caused the stock price to recede and for future earnings estimates to decline as of late.
