MTAR Technologies shares fell between 12% and 13% Thursday following a setback for key customer Bloom Energy [1, 2].

The decline highlights the risk of high customer concentration for the precision engineering firm, which relies heavily on a single partner for its growth.

Bloom Energy encountered a setback regarding the 1.8 GW Crusoe data-center project [1]. This project is critical for MTAR because the company derives 55% to 65% of its total revenue from Bloom Energy [1]. The inability to secure expected orders for the data center has triggered a significant investor sell-off.

Market analysts said Bloom Energy contracts can be highly lucrative for MTAR. Potential order values are estimated between ₹900 crore and ₹1,100 crore per gigawatt [1]. The disruption of the Crusoe project threatens these projected revenue streams.

In response to the volatility, Indian stock exchanges have taken regulatory action. Both the BSE and NSE placed MTAR Technologies under a long-term Additional Surveillance Measure (ASM) [2]. This measure is designed to monitor stocks with high volatility or unusual price movements to protect investors.

While the share price tumbled over 12% according to some reports [2], other data indicates a drop of 13% [1]. The company's heavy dependence on the success of Bloom Energy's energy solutions makes it vulnerable to the partner's operational hurdles.

The situation underscores the systemic risk MTAR Technologies faces due to its narrow revenue base. When a company depends on one client for more than half of its income, any operational failure by that client—such as the Crusoe data-center setback—creates an immediate and disproportionate impact on the supplier's valuation. The ASM classification further signals that regulators are concerned about the stock's stability.
