Shares of Natco Pharma Ltd training higher after its Visakhapatnam-based finished dosage formulations facility received four observations from the US Food and Drug Administration (USFDA).

The USFDA conducted these inspections between 17 August and 21 August 2026. The company said the observations are procedural in nature and that it is confident of addressing them within the stipulated timelines.

The inspection was carried out at Natco Pharma’s FDF manufacturing plant at Parawada, Visakhapatnam, Andhra Pradesh. At the end of the inspection, the USFDA issued a Form 483 containing four observations. 

A Form 483 is issued when FDA inspectors identify conditions that may potentially violate requirements under the Food, Drug, and Cosmetic Act.

Natco Pharma has described the observations as procedural in nature and said it will address them comprehensively within the required timelines. The company has not disclosed detailed information on each of the four observations, so their individual regulatory significance cannot yet be assessed.

The development is important because the US remains a key market for Indian pharmaceutical companies, making regulatory compliance at manufacturing facilities a critical factor for maintaining supplies and approvals. 

While a Form 483 does not by itself represent a final FDA determination or automatically result in regulatory action, the company’s response and subsequent FDA assessment will remain important.

Natco has faced USFDA scrutiny at other facilities in the past, making the latest inspection another development investors will monitor closely. However, the company has currently characterised the latest findings as procedural rather than indicating a serious compliance failure.

The market reaction has so far been relatively limited. At 12:48 pm, Natco Pharma shares were trading around Rs 885.70 on August 24, up about 0.36%, after touching an intraday high of Rs 892.40.
