We maintain a BUY with a TP of Rs 639/sh (18x Mar-20E EPS). PSPs 1QFY19 revenue of Rs 2.3bn (+50.6%YoY, -11.0% QoQ) was largely driven by the SDB project (~Rs 830mn). EBITDA margin came in at 14%, about 100bps higher than management guidance. Change in project mix (SDB still in initial stage where material cost is significantly higher than labour) was key reason.
