Here's the thing about Data Patterns (India) Limited — the stock has jumped about 54% year-to-date in 2026, yet the latest quarter tells a very different story.
Revenue dropped to ₹133.25 crore from ₹307.46 crore, down about 57% year-on-year. Investor Presentation
So why did the shares rally roughly 8.7% after these results? The answer isn't in the quarterly earnings themselves. It's in what lies ahead.
The headline number everyone talks about is ₹2,698 crore — the order book including orders received and negotiated. That's about 2.9 times FY26 revenue of ₹925 crore. On paper, that looks like solid revenue visibility for nearly three years. Investor Presentation
But here's the catch. About ₹970 crore of that book is negotiated but not yet formally contracted. The firm order book — the money actually in the door — stands closer to ₹1,724 crore. That's still roughly 1.9 times FY26 revenue, which isn't bad, but it's not the ₹2,698 crore figure making headlines. Investor Presentation
The conversion timeline matters too. Large project orders typically take 18–24 months to execute, while smaller DRDO subsystem orders move faster. HAL contracts stretch over 2–3 years. The negotiated orders have already slipped by more than 1.5 years due to approval delays, with the customer taking another two-month extension. Management expects those contracts to be placed within roughly two months. Transcript +1
This lumpiness is baked into the business model.
The rally narrative often talks about margin expansion. The Q2 numbers tell a different story. EBITDA margin actually contracted to 23.6% in Q2 from 27% in the previous quarter. It's higher than the 22.3% posted in Q2 FY26, but that's because last year's quarter was unusually strong on revenue. Investor Presentation
Management attributes margin pressure to elevated employee costs from capability expansion and a shift in product mix. Other expenses are among the highest in the industry, and the company keeps spending whether or not products ship in a given quarter. Gross margins remain healthy — around 69% in Q2 — but overheads are eating into profitability. Transcript +2
For the full year FY27, management targets 20–25% revenue growth and EBITDA margins of 35–40%. Here's the math: H1 revenue was about ₹249 crore. To hit the guidance, H2 needs to deliver roughly ₹860–905 crore. That's about 65–75% higher than FY26's H2. It's a steep climb that assumes flawless execution and timely placement of those negotiated orders. Transcript
Goldman Sachs has been tracking this closely. The firm initiated coverage in October 2025 with a Buy rating and a target price of ₹3,640, citing the company's cost-efficient design approach and higher EBITDA margins than peers.
The downgrade wasn't about the company's fundamentals falling apart. It was about valuation. Goldman noted the stock was trading at the upper end of its historical range and saw limited near-term catalysts. The brokerage also flagged that the revenue mix is shifting toward defence public sector undertakings, which typically offer lower profitability than Ministry of Defence and DRDO contracts.
Goldman's earnings estimates for FY27–FY29 sit below consensus, reflecting expectations of lower revenue growth and EBITDA margins than the broader market. The firm also pointed out that the order book had remained range-bound with a book-to-bill ratio below one due to robust execution, and visibility on incremental inflows from defence PSUs remained relatively low.
At the current price around ₹4,025, Goldman's target implies roughly 3.5% upside — hardly the stuff of a continued 54% rally.
When you compare Data Patterns to other defence players, the execution gap becomes clear.
Bharat Electronics posted 26% revenue growth and 20% profit growth. Data Patterns was the outlier with declines across the board. Investor Presentation
On order inflows, however, Data Patterns shows strength. H1 FY27 order inflow of ₹1,046 crore was nearly three times H1 FY26. That's better growth than Astra Microwave, which saw about 42% inflow growth in Q1, and far stronger than Bharat Electronics, whose H1 inflow fell 36–44%. Investor Presentation +5
The competitive advantage lies in intellectual property and vertical integration.
With about 1,100 engineers and a 10.28-acre Chennai manufacturing facility, the company has built deep capabilities that act as barriers to entry. The Stac acquisition is expected to improve gross margins through in-house manufacturing and better quality control. Transcript +3
Policy developments are working in the company's favor, at least on paper. The draft Defence Acquisition Procedure (DAP) 2026 proposes simpler acquisition categories, stronger support for indigenous design, and indigenous content requirements of up to 60%. This aligns perfectly with Data Patterns' IP-led model.
But policy doesn't eliminate execution friction. Management has repeatedly pointed to delays in approvals and qualifications. One large programme stretched by more than 1.5 years, and BrahMos seeker approvals are taking time. The Air Force's AMCA-related request for proposal was still unpublished as of Q2 FY26.

The government has streamlined procurement procedures worth nearly ₹1 lakh crore through faster approvals and relaxed penalties for indigenous projects. Yet on the ground, Data Patterns is still waiting for negotiated orders to convert and customer inspection teams to show up.
The 54% YTD rally in Data Patterns isn't wrong — it's just forward-looking. The market is pricing in a strong H2 recovery, successful conversion of negotiated orders, and sustained order inflows beyond the current book. The order book provides a foundation, but the execution risk is real.
Goldman Sachs' downgrade to Neutral reflects this tension. The firm likes the business model and earnings trajectory but believes the valuation already captures much of the upside. For the rally to continue, the company needs to deliver on its back-ended guidance and show that order inflows can accelerate despite the shift toward lower-margin PSU work.
The numbers from Q2 don't support the rally on their own. The story does — if you believe in the conversion.
