India Ratings and Research (Ind-Ra) has downgraded Safety Controls & Devices Pvt Ltd s (SCDPL s) long-term issuer rating to BB with a negative outlook from BB-plus. The company is a leading engineering, procurement and construction contractor of sub-station and fire protection engineers in north India. Ind-Ra said the downgrade reflects a significant decline in SCDPL s revenue in FY20, leading to deterioration in its EBITDA and credit metrics. The revenue plunged to Rs 26 crore in FY20 from Rs 101 crore in the year-ago period due to slower pace of execution of orders. The land availability issues were further aggravated by Covid-19 led supply chain disruptions.
