Dongwu Securities released a research report on April 17 stating that it gave Kostar (002518.SZ) a purchase rating. The main reasons for the rating include: 1) energy storage delivery fell short of expectations in 23 due to overseas household storage inventories, and charging piles doubled; 2) data centers took advantage of high growth and active layout to achieve breakthroughs in various fields; 3) the 23Q4 fee rate increased sequentially, and order preparation led to an increase in inventory throughout the year.
