MTAR Technologies slips 12% as Bloom project pauses

What happened to MTAR Technologies shares

Shares of MTAR Technologies Ltd fell sharply in Thursday’s trade, sliding 12.16% to hit a low of ₹6,242.25. The stock was also reported to have opened lower at ₹7,100 on NSE and touched an intraday low of ₹6,330, down about 11%. Around 1 pm, it was seen trading near the day’s low at about ₹6,402, down 9.9%. In another update from the same trading day, MTAR Tech was cited as down about 9% and trading near ₹6,470 after falling more than 13% in two days.

The slide came after a strong run-up in the counter, with market participants pointing to profit-booking as a key driver. At the same time, investor sentiment weakened due to concerns around Bloom Energy Corp, a major US-based client of MTAR Technologies. The company was also placed under the long-term Additional Surveillance Measure (ASM) framework by BSE and NSE, which is typically used to caution investors when a stock sees high volatility.

The trigger: Bloomberg report on a paused data-centre project

The immediate concern linked back to a Bloomberg report on Crusoe Energy Systems LLC, a data-centre developer serving companies such as OpenAI and Microsoft. The report said Crusoe paused work on a planned 1.8-gigawatt data-centre campus in Cheyenne, Wyoming. The project was expected to be powered by 900 MW of Bloom Energy fuel cells along with grid electricity.

Crusoe said in a statement: “At the request of our customer, Crusoe has paused its development activities,” without disclosing the customer’s name. Following the report, Bloom Energy’s stock was cited as tumbling 10% overnight, which fed into negative sentiment around its suppliers and partners.

Why Bloom Energy matters for MTAR Technologies

MTAR Technologies is described as a critical manufacturing partner for Bloom Energy. It manufactures and fabricates critical assemblies for the US-based company, including supplying power units, specifically hot boxes, for over nine years. MTAR is also developing and manufacturing hydrogen boxes and electrolysers for Bloom Energy.

Importantly for investors, Bloom Energy was described as the single largest client for MTAR Technologies, contributing more than 55% of the company’s total revenue. That concentration risk became a central talking point once the data-centre project pause surfaced.

Profit-booking after a rally adds to the pressure

Alongside the client-related concern, market participants attributed the fall to profit-booking after a strong rally. The stock had earlier seen volatility after profit booking and concerns related to one of its international clients.

Technical commentary also pointed to weakening momentum. Osho Krishan, Chief Manager – Technical & Derivative Research at Angel One, said MTAR Tech “has seen a decent profit booking after an elongated period of rally and has slipped below its 21 DEMA.”

Exchanges place MTAR Tech under long-term ASM

BSE and NSE placing MTAR Technologies under the long-term ASM framework added another layer of caution. Exchanges use short-term or long-term ASM frameworks to alert investors about unusually high price volatility.

ASM is not a ban, but it can change trading dynamics by increasing scrutiny and, in some cases, tightening trading conditions. For a stock already reacting to client headlines and profit-taking, the ASM tag can reinforce risk-off behaviour among traders.

Recent fundamentals: results, valuation concerns, and order wins

In another recent trading session, MTAR Technologies posted Q4 net profit of ₹44.28 crore, up 223% year-on-year, and revenue of ₹306.1 crore, up 67%. Despite these numbers, the share price dropped 4.16% to ₹6,248.50 on May 12, 2026, with the fall attributed to profit-taking after a sharp rally and elevated valuation.

The valuation metrics cited in the same context included a PE of 302.88 and a price-to-book multiple of 24.69 times. There were also concerns flagged around input costs potentially squeezing future margins, even though EBITDA margin expanded 150 basis points year-on-year to 20.2%. Motilal Oswal Financial Services Ltd (MOFSL) said MTAR’s operating performance came in below estimates, while earnings were largely in line with expectations.

On the positive side, Ravi Singh, Chief Research Officer at MasterTrust, said the long-term outlook still looks positive, especially after the company secured a large international order worth over ₹2,200 crore, improving future revenue visibility. In another report, the international order win was cited at ₹2,279 crore, alongside upgraded FY27 growth guidance, and the stock was reported to have surged up to 9% intraday on May 14.

Technical levels and near-term trading cues

AR Ramachandran, a Sebi-registered research analyst at Tips2trades, said MTAR’s stock is bearish on daily charts with strong resistance at ₹6,622. He added that a daily close below the support of ₹6,000 “could trigger a fall towards ₹5,310 in the near term.”

Such levels gained attention as the stock moved sharply within a narrow band of investor sentiment drivers: profit-booking after an extended rally, valuation debate, and headline risk around a key customer.

Other sentiment factors: promoter encumbrance disclosure

A separate disclosure also coincided with a sharp fall in the stock in another session. MTAR Technologies informed stock exchanges about an encumbrance of 60,000 equity shares by Mrs. Kavitha Reddy Gangapatnam, a member of the promoter group. While pledging shares does not necessarily indicate financial distress, it can sometimes be perceived as a sign of liquidity pressure and can affect sentiment.

Key data points at a glance

Why the move matters for investors

The sharp fall highlighted how quickly sentiment can turn when a stock combines high volatility, concentrated client exposure, and a strong prior rally. The Bloomberg-linked pause in a major US data-centre project directly raised questions about near-term demand visibility for Bloom Energy, and by extension, for key suppliers.

At the same time, MTAR Technologies continues to be positioned around opportunities in clean energy, aerospace, nuclear, and defence. Investors are now balancing those longer-cycle themes against near-term trading risks, including ASM tagging, technical breakdown levels, and client-linked headline flow.

Conclusion

MTAR Technologies’ Thursday decline was driven by profit-booking and renewed concerns around Bloom Energy after a key US data-centre project was paused, with the stock also placed under long-term ASM by exchanges. Going forward, investors are likely to track updates related to Bloom Energy-linked projects, trading conditions under ASM, and any further company disclosures tied to orders, guidance, or client concentration.
