We received fresh orders worth Rs. 929 crores in Q2FY27, taking H1FY27 inflows to Rs. 1,046 crore, nearly three times the level recorded in H1FY26. Our current order book, including orders received and negotiated, stands at approximately Rs. 2,698 crores, providing healthy revenue visibility. We are also seeing encouraging opportunities for larger, complete-system contracts across radar, electronic warfare and communication systems, supported by our investments in technology and manufacturing capabilities. Q2FY27 was a more muted quarter from a revenue perspective, following the exceptionally strong execution in Q2FY26. With several programs milestones progressing and deliveries expected to pick up, we expect H2FY27 to be stronger than H1FY27, supported by our healthy order book and execution momentum.

We remain on track to achieve our full-year targets, and our FY27 guidance remains unchanged" About Data Patterns Data Patterns’ core competencies include design and development across electronic hardware, software, firmware, mechanical, product prototype besides its testing, validation and verification.
