Zhongji Innolight is poised for strong consensus-beating growth over the next two years. Its leading market position helps it secure critical upstream components amid industry-wide shortages. The Hong Kong listing proceeds will accelerate overseas expansion (Thailand), capturing more market share, and the company is actively managing geopolitical exposure by shifting production and reducing domestic revenue reliance to single digits.
