NSE SME Stock Hits Upper Circuit, Delivers 53% Returns In 2026 So Far | Do You Own?

NSE SME Stock: Atmastco Limited ended 5% higher on Monday, May 11, a day after the company shared update related to its defence arm. The NSE SME stock has delivered nearly 53% returns since the beginning of the year 2026.

Amtastco shares ended 4.93% higher at Rs 204.6 per share on NSE with a market capitalisation of Rs 506.07 crore on Monday. The stock had touched an intraday high of Rs 214.80 per share and an intraday low of Rs 194 per share during the trading session.

The company scrip locked in the upper circuit after its defence arm obtained Bureau of Indian Standards certification for Level-6 bulletproof jackets, a key approval that enables commercial sales for institutional and government customers in India's defence market.

The micro cap stock, mainly active in trading steel goods, industrial items, and engineering and erection work, drew strong investor interest after the update, as the certification is compulsory for supplying such protective equipment to official procurement channels.

The company said the BIS approval enhances Atmastco Defence Systems' standing within defence manufacturing, improves trust among customers and agencies, and supports partnerships, while also allowing the start of commercial production of Level-6 bulletproof jackets that may add new revenue streams over time.

The management described the BIS certification as a major achievement that reflects Atmastco Defence Systems' technical skills, manufacturing discipline, and adherence to quality compliance, while investors viewed it as a development that could help Atmastco Limited deepen its position in a defence sector where domestic manufacturing and indigenous equipment demand are increasing.

The disclosure added that Atmastco Defence Systems plans to grow its portfolio in defence and protective equipment, including advanced safety solutions besides bulletproof jackets, with continued emphasis on innovation, regulatory compliance, and product development tailored to evolving defence requirements.

Atmastco Limited operates as an engineering and manufacturing company involved in steel fabrication, EPC projects, defence products, and industrial infrastructure offerings, serving industries such as power, steel, railways, mining, and defence, while the subsidiary Atmastco Defence Systems focuses specifically on protective gear and related defence manufacturing.

On a year-on-year basis, the company reported weaker financial performance, with lower revenue, operating profit, and net profit compared with the previous financial year.
