Huajin Securities released a research report on April 24 stating that it gave Holevo (688682.SH) an increase in holdings rating. The main reasons for the rating include: 1) steady growth in revenue, fluctuations in gross margin and cost increases are dragging down profits; 2) stealth and satellite measurement systems have increased dramatically, and the development of phased array prototypes is pending; 3) continuous increase in R&D investment to lay out low-altitude economy+low-orbit satellite tracks; 4) self-developed domestic RDSim software, which can be expected to replace domestic production.
