NACL reported an improved 4QFY20 result, as expected, driven by lower cost of production. We raise our FY21 EBITDA estimate to factor lower input costs in FY21. Revenue declined 30% YoY (-7% QoQ) to INR19.4b on a lower LME aluminum price of USD1,694/t (-9% YoY, -3% QoQ). EBITDA at INR2.1b (+507% QoQ) came in above our estimate of INR1.2b, led by lower-than-expected production costs. Reported EBITDA still declined 60% YoY due to lower alumina and aluminum prices. EBIT loss was at INR0.2b (v/s INR1.9b profit last year); revenue declined to INR11.3b (-34% YoY, -15% QoQ) on lower LME prices/volumes due to the impact of COVID-19. Realization declined 8% YoY (and 3% QoQ) to USD1,905/t on account of lower LME and premiums. As a result, Operating Cashflows (OCF) were negative at INR3.5b. With estimated gradual recovery in aluminum demand, we expect prices to rise further.
