GlaxoSmithKline Pharmaceuticals’ (GSKP) Q3FY23 performance beat our estimates on the profitability front, led by prudent cost controls. Revenues declined 1.7% YoY to Rs8bn (I-Sec: Rs8.8bn) with slowdown in vaccine sales. EBITDA margins saw strong YoY expansion of 430bps (+50bps QoQ) to 28.5%, largely supported by gross margin expansion and lower ‘other expenses’.
