Dr Reddy’s Laboratories shares drop sharply after the company informs stock exchanges that certain batches of its semaglutide product are out of specification due to an issue related to the active pharmaceutical ingredient (API) used in those batches. Multiple outlets report declines of about 4% to 7% in early trading, with one report noting a fall of around 6.5% to Rs 1,261 on the BSE. The company says an investigation is underway to identify the root cause and that corrective measures are being taken to ensure product quality. Several reports also state that commercial supplies of semaglutide will be delayed until the issue is resolved, raising concerns about availability. The company further clarifies that the development does not impact patient safety or its existing global regulatory filings. The disclosures are consistent across outlets: a quality concern tied to API results in batches being out of specification, and the company moves to prevent further impact by pausing deliveries until quality checks are completed.
