Shares of Tata Group companies experienced notable declines following their first-quarter financial updates for fiscal year 2026. Trent, the retail arm of Tata Group, saw its stock price drop between 9% and nearly 12% after reporting a 20% year-on-year increase in standalone revenue to Rs 5,061 crore for the quarter ended June 2025. Despite the revenue growth, the business update fell short of market expectations, raising concerns about its growth momentum. Similarly, Titan's shares fell by 5% to 6% after a Q1 business update that failed to meet investor expectations. Tata Steel reported a slight decline in production and delivery volumes in India, with production slipping 0.2% year-on-year to 5.26 million tonnes and delivery volumes down 3.8% to 4.75 million tonnes. However, the company noted strong growth in automotive, retail, and online sales segments, while European operations remained steady. Tata Steel's shares declined about 2% following the update, with 2.81 million shares traded in a block deal. Union Bank shares fell over 4% after reporting the weakest loan growth in the last four quarters and a 0.8% quarter-on-quarter decline in gross advances, marking its third consecutive session of losses. Phoenix Mills also experienced a 3% decline, falling below a three-session low. Nykaa saw 1.25 million shares traded in a block, though no price movement was specified.
