Black Box Q1 FY27: revenue ₹1,719 cr, PAT +18%. Black Box Ltd. Ask iris. Record quarter sets the tone for FY27. Black Box Ltd (NSE: BBOX) reported its strongest June-quarter performance yet, led by higher execution and a record order pipeline. On the Q1 FY27 earnings call dated August 13, 2026, management highlighted that the quarter delivered the company's highest-ever quarterly revenue and a sharp improvement in profitability. The performance matters because Black Box is positioning itself around large global data center and AI infrastructure programs where scale and execution discipline decide outcomes. The company also pointed to improving supply chain conditions and better mix as supportive factors. Investors tracked the updates closely given the visibility provided by the order backlog. Q1 FY27 financial performance: revenue, profit, and EPS. For the quarter ended June 30, 2026, consolidated revenue from operations came in at ₹1,718.50 crore, up 23.92% year-on-year (YoY) from ₹1,386.74 crore in Q1 FY26. On a quarter-on-quarter (QoQ) basis, revenue rose 1.63% from ₹1,690.94 crore in Q4 FY26. Total income stood at ₹1,722.25 crore, up 24.04% YoY and 1.72% QoQ. Consolidated profit after tax (PAT) was ₹55.92 crore, up 17.90% YoY, but down 13.65% QoQ compared with ₹64.76 crore in Q4 FY26. Basic and diluted EPS for Q1 FY27 was ₹3.15, compared with ₹2.80 and ₹2.79 in Q1 FY26, and ₹3.78 and ₹3.75 in Q4 FY26. EBITDA improves as margins expand. Black Box reported EBITDA of ₹160 crore in Q1 FY27, up 38% YoY from ₹116 crore in the corresponding quarter last year. EBITDA margin improved to 9.3% from 8.4%, an expansion of 90 basis points. Management attributed the margin improvement to operating leverage, a better business mix, and productivity initiatives linked to GCC and AI-led programs. The company also reiterated a medium-term target of reaching 10% EBITDA margin or above. The Q1 margin outcome aligned with the FY27 guidance band, suggesting the company is aiming to hold the gains while scaling execution. Order bookings surge; backlog hits record high. Order bookings for the quarter were US$139 million, and the total order backlog rose to around US$149-950 million, up 83% YoY. The company described the backlog as a record level, providing stronger revenue visibility. Black Box also noted that data center engagement tenures have extended to 24-36 months, which can help smoothen conversion over subsequent quarters. In rupee terms, the backlog was cited as equivalent to ₹8,986 crore. This order stack is central to the company's FY27 outlook, especially as Q1 is typically described by management as a softer quarter in terms of conversion. Major hyperscaler win highlights AI infrastructure positioning. A key Q1 win included a new global hyperscaler client in the US with an order valued at US$131 million, with the company also disclosing an approximate rupee value of ~₹1,240 crore. Management indicated this win validates Black Box's capabilities and scale in the AI infrastructure market. The company described the scope as 100% services. It also indicated that large hyperscaler projects are expected to ramp from November onward, with some growth expected to spill into FY28. Brazil acquisition 2S adds to reported revenue. Black Box said Q1 revenue included about ₹60 crore from the Brazil acquisition 2S, reflecting around two months of contribution. The company stated the balance of the quarter's growth was entirely organic. This split is important because it frames the quarter's revenue momentum as largely driven by execution rather than only consolidation effects. Management commentary also connected performance to disciplined execution and improved operating leverage. Tax rate and profitability drivers. Management flagged a low effective tax rate in the range of 10-15% expected for FY27-28, supported by the consumption of carry-forward operating losses across geographies. It also indicated the tax rate is expected to normalize to around 20% post FY28. In Q1, PAT growth of 18% YoY was cited as being aided by the lower effective tax rate. Profit before tax for Q1 FY27 was ₹61 crore, up 35% from ₹45 crore in Q1 FY26. FY27 guidance: revenue, EBITDA, and PAT targets. Black Box maintained a confident FY27 outlook built around stronger backlog conversion, especially in the second half of the year. Guidance includes revenue of ₹7,800-8,000 crore (23-27% growth) and EBITDA of ₹700-725 crore (27-32% growth). EBITDA margin is guided at 9.3-9.4%, up 30-40 basis points. PAT is expected at ₹325-350 crore, implying growth of 38-50%. On the order side, the company expects to exit FY27 with backlog of US$1.4-1.5 billion (65-75% growth) and full-year order bookings of US$1.3-1.4 billion (45-50% growth).

Key numbers at a glance. | Metric | Q1 FY27 | YoY change | QoQ change / comparison | | Revenue from operations | ₹1,718.50 crore | +23.92% | +1.63% vs ₹1,690.94 crore | | Total income | ₹1,722.25 crore | +24.04% | +1.72% vs ₹1,693.08 crore | | EBITDA | ₹160 crore | +38% | Not stated | | EBITDA margin | 9.3% | +90 bps | Not stated | | PAT | ₹55.92 crore | +17.90% | -13.65% vs ₹64.76 crore | | EPS (basic) | ₹3.15 | Compared with ₹2.80 (Q1 FY26) | Compared with ₹3.78 (Q4 FY26) | | Order bookings | US$139 million | Not stated | Not stated | | Order backlog | ~US$149-950 million | +83% | Not stated | FY27 outlook summary. | Guidance item (FY27) | Company guidance | Growth (as stated) | | Order backlog (FY27 exit) | US$1.4-1.5 billion | +65-75% | | Order bookings | US$1.3-1.4 billion | +45-50% | | Revenue | ₹7,800-8,000 crore | +23-27% | | EBITDA | ₹700-725 crore | +27-32% | | EBITDA margin | 9.3-9.4% | +30-40 bps | | PAT | ₹325-350 crore | +38-50% | Why this quarter matters. The quarter combined record revenue with a step-up in margin, which is critical for a services-heavy infrastructure business where execution and utilization drive outcomes. The record backlog and large hyperscaler deal provide tangible visibility, especially as management expects stronger conversion in H2. At the same time, the QoQ dip in PAT and EPS compared with Q4 FY26 shows the quarter did not improve on every metric sequentially, even as YoY momentum remained strong. Investors will likely monitor whether the guided margin band holds as project ramps begin from November, and how quickly large orders translate into billed revenue. Closing takeaway. Black Box's Q1 FY27 results showed record revenue of ₹1,719 crore, EBITDA margin expansion to 9.3%, and a sharp rise in order backlog to about US$150 million. The company's FY27 guidance sets clear targets across revenue, EBITDA, and PAT, backed by higher bookings expectations. The next major checkpoint will be the post-Q2 update, which management said could improve clarity on backlog consumption and incremental ordering between October and March.
