Data Patterns drops 11% on FY27 margin guide in 2026

What triggered the sharp fall

Data Patterns’ shares slid as much as 11% on the BSE on Friday after investors reacted to the company’s FY27 profitability outlook, announced alongside its March-quarter results. The stock touched an intraday low of ₹3,566.25, down 11.04% at the day’s worst point. By 12:20 PM, it had recovered part of the decline and traded 4.7% lower at ₹3,825.10 per share. The move stood out against the broader market, with the BSE Sensex up 131 points, or 0.17%, at the time.

The immediate concern was management’s guidance for a sharp compression in operating margins in FY27. Data Patterns said it closed FY26 with an EBITDA margin of 56%, but is aiming to maintain EBITDA margins at around 35-40% in FY27. The gap between the reported FY26 margin level and the FY27 target range became the dominant market signal, outweighing a strong jump in quarterly profit.

FY27 margin guidance: the key overhang

The margin guidance is notable because Data Patterns’ Q4FY26 margins were elevated: gross margin was 73% and EBITDA margin was 56% during the quarter. A shift to 35-40% in FY27 implies a materially different profitability profile. The company had previously seen margin volatility, including a reported drop to 22.3% in Q2 FY26 due to competitive pricing on a large project.

Investors typically track defence electronics players for order visibility and execution, but also for steady margins given the specialised nature of their work. When guidance points to sustained margin pressure, valuations can get reassessed quickly, especially for stocks priced for high profitability.

Q4FY26 revenue fell year-on-year, rose sequentially

For the March 2026 quarter (Q4FY26), Data Patterns reported net revenue of ₹344.8 crore, a 13% year-on-year decline from ₹396.2 crore in Q4FY25. Sequentially, revenue improved sharply from ₹173.1 crore in the prior quarter. The quarterly pattern suggests uneven timing in project execution and billing, which is common in defence and aerospace programs.

The company also disclosed segment mix for the quarter. Avionics contributed 48.5% of revenue, followed by the FCS segment at 20.8%. This mix matters because profitability can vary across programs and delivery stages, and changes in mix can affect margins even when the order pipeline remains strong.

Profit and operating performance: EBITDA and PAT surged

Despite the year-on-year decline in revenue, operating profit rose strongly. EBITDA jumped 29% year-on-year and 148.5% quarter-on-quarter to ₹192.8 crore. Net profit (PAT) increased 21.3% year-on-year and 137.3% quarter-on-quarter to ₹138.4 crore.

The combination of lower revenue but higher profits points to improved profitability in the quarter, supported by high gross margins and a strong EBITDA margin. This makes the FY27 margin range of 35-40% even more central to the market debate, because it indicates the current margin level may not be sustained.

Order book: higher quarter-end figure and an all-time high claim

Data Patterns said its order book at the end of the March quarter stood at ₹926.5 crore, up from ₹743.4 crore at the end of December 2025. Separately, the company’s chairman and managing director Srinivasagopalan Rangarajan stated that the order book stands at an all-time high of about ₹2,062 crore, the highest in the company’s history, and that it provides revenue visibility over the coming years.

Management also cited a healthy executable pipeline across radars, electronic warfare, and advanced defence electronics. The company guided for revenue growth of 20-25% over the next two to three years.

What Motilal Oswal flagged before the analyst call

Ahead of the company’s analyst call, Motilal Oswal maintained a ‘Neutral’ rating on Data Patterns. The brokerage said consolidated revenue was lower than its estimate of ₹400 crore for the quarter, but EBITDA was higher than its expectation of ₹180 crore. It also said EBITDA margin beat its expectation of about 45%, while adjusted PAT was in line.

This framing highlights the cross-currents: execution and margin delivery in Q4 were strong versus expectations, but the near-term debate has shifted to the margin outlook and what it implies for future earnings quality.

Valuation sensitivity: why guidance can move the stock

The text also notes that Data Patterns’ valuation looks elevated versus some industry peers. It cites a market capitalisation of about ₹22,500 crore and a price-to-earnings range of 91-95 times trailing earnings. For comparison, it cites Bharat Electronics (BEL) trading at 52-59 times P/E and Hindustan Aeronautics (HAL) at 32-47 times P/E.

It also mentions analyst price targets suggesting limited immediate upside, with an average 12-month forecast range of ₹3,000 to ₹3,800. In such a setup, any indication of structurally lower margins can drive swift de-rating risk, even if order inflows and long-term growth expectations remain intact.

Broader defence backdrop mentioned in the text

The text links the company’s pipeline to broader tailwinds for India’s defence sector. It cites an allocation of ₹784,000 crore (₹7.84 trillion) for defence in the 2026-27 Union Budget, with capital expenditure up 21.8% and 75% of the capital acquisition budget reserved for domestic companies.

While these sector factors can support longer-term demand, Friday’s market reaction suggests investors were more focused on company-level margin guidance and the implications for near-term profitability.

Key numbers at a glance

Conclusion

Data Patterns’ Q4FY26 results showed sharp sequential improvement in revenue and strong growth in EBITDA and net profit, alongside high quarterly margins. But the stock’s steep reaction underlined that FY27 guidance for EBITDA margins of 35-40% is the key variable investors are reassessing. The next market checkpoint is the company’s analyst call and any additional detail on the margin trajectory, project mix, and execution plan supporting its 20-25% revenue growth guidance over the next two to three years.
