Black Box Q1 FY27: Record revenue, a bigger backlog, and a data center mix shift

Black Box Limited opened FY27 with its highest ever quarterly revenue, supported by faster execution of an expanding order book and a partial contribution from its newly acquired Brazil business, 2S. Consolidated revenue from operations for Q1 FY27 stood at 1,719 crore, up 24% year on year versus 1,387 crore in Q1 FY26. Profitability improved faster than revenue. EBITDA rose to 160 crore, up 38% year on year, and EBITDA margin expanded to 9.3% from 8.4% in the year-ago quarter. PAT increased to 56 crore, up 18% year on year.

Management positioned the quarter as a continuation of a multi-year transformation that is now shifting into a scaling phase. The key operating signal in the deck and the concall was the strengthening of demand visibility. Order bookings in Q1 FY27 were 339 million dollars and the order backlog rose to 949 million dollars, with the company highlighting longer tenure engagements and a greater share of project-led business.

The backlog is rising, and the revenue mix is moving toward longer programs

The investor presentation shows that order backlog has expanded sharply over the last year, rising from 504 million dollars in Mar 2025 to 792 million dollars in Mar 2026 and 949 million dollars by Jun 2026. Importantly, the mix is also changing. Projects account for 46% of the Jun 2026 backlog, up from 37% in Mar 2026. Management stated that the average tenure of backlog has increased from 12 to 15 months in FY26 to around 18 months, with data center projects typically running 24 to 36 months.

This matters because Black Box is increasingly participating in large data center infrastructure programs, particularly in the US. The company said its win-rate for large deals has improved by more than two times, aided by better pipeline conversion, especially in the data center business. A notable Q1 FY27 win included a 131 million dollar engagement with a new US-based hyperscaler.

The company also expects a meaningful shift in revenue mix in FY27. The deck states that data center revenue contribution was about 17% in FY26 and is expected to rise to about 30% in FY27 due to execution of large data center orders.

Financial performance: growth with operating leverage, but cash conversion remains a focus area

On the P&L, Q1 FY27 gross margin was steady at 30.5% (vs 30.9% in Q1 FY26). The improvement in EBITDA margin was driven by operating leverage and productivity gains, with management citing centralized delivery, procurement discipline, and AI-led productivity initiatives.

However, finance costs increased. Q1 FY27 finance cost was 48 crore versus 34 crore in Q1 FY26. Management also attributed PAT growth being lower than EBITDA growth partly to higher exceptional items and higher finance costs.

Working capital remains a key point to monitor. The historical cash flow table in the deck shows that FY26 cash generated from operations was 111 crore despite EBITDA of 570 crore, reflecting the drag from working capital changes. The balance sheet snapshot shows trade receivables rising to 1,153 crore as of Mar 2026 from 567 crore as of Mar 2025. Management stated in the concall that improving operating cash flow to EBITDA conversion is a priority for FY27, supported by disciplined working capital management.

FY27 guidance: quantified, with an execution timing caveat

Black Box provided full-year guidance across order metrics and financials. For FY27, the company guided revenue of 7,800 to 8,000 crore and EBITDA of 725 to 750 crore, with EBITDA margin of 9.3% to 9.4%. PAT guidance was 300 to 325 crore.

On the order side, the company guided FY27 order backlog of 1,300 to 1,400 million dollars by March 31, 2027 and FY27 order bookings of 1,325 to 1,450 million dollars.

A notable nuance from the concall was the discussion on revenue phasing. Management clarified that large hyperscaler and data center engagements do not always convert to revenue immediately after order award, because customer site readiness and deployment timelines influence when work starts on the ground. In response to a question on conservatism, management indicated that part of the current backlog is likely to spill into FY28, which supports the view that the FY27 revenue guide is based on expected execution schedules rather than backlog size alone.

M&A and FY30 aspiration: 2S adds a Latin America platform

The company reiterated its FY30 aspiration to reach 18,000 crore (2 billion dollars) of revenue, with around 12,000 crore from organic growth and around 6,000 crore from inorganic growth. The presentation described an acquisition approach built around identifying sub-optimal margin businesses for capability expansion, acquiring complementary businesses to scale, and transforming acquired entities by executing synergies and exiting non-strategic low-margin segments.

The Brazil acquisition, 2S Inovações Tecnológicas, was highlighted as an early step in this path. The deck states that the acquisition is intended to add annualized revenue of about 500 crore in FY27. In the concall, management quantified that 2S contributed about 60 crore in Q1 FY27, reflecting two months of consolidation.

Takeaways

Black Box entered FY27 with strong reported growth, margin expansion, and a record order backlog. The presentation and concall repeatedly emphasized that the current demand cycle is being driven by AI-led digital infrastructure and data center build-outs, with Black Box aiming to benefit through large multi-year programs. Guidance for FY27 is clearly quantified across the income statement and order metrics.

At the same time, two practical execution variables will remain central to investor tracking through FY27: working capital and the pace at which large orders convert into on-the-ground execution. Management has acknowledged the dependency on customer timelines for hyperscaler programs and has stated that cash conversion should improve with tighter working capital discipline. If those two elements move in the right direction alongside a rising data center mix, the company’s stated objective of reaching a 10% EBITDA margin at scale becomes more testable over the next few quarters.
