Revenue from operations came in at ₹1,910 crore for the quarter, up from ₹1,019 crore a year ago.

Q1FY27 financial performance at a glance

STL’s revenue momentum has been visible over multiple quarters. The company’s revenue has risen for the last five quarters, from ₹1,020 crore to ₹1,920 crore, with an average increase of 14.2% per quarter. In Q1FY27, revenue growth was supported by a stronger mix of optical connectivity demand and ongoing network investments globally.

Operating profitability improved materially. EBITDA stood at ₹397 crore in Q1FY27, up from ₹140 crore in Q1FY26 and ₹218 crore in Q4FY26. Profit before tax rose to ₹257 crore versus ₹13 crore a year ago and ₹109 crore in the previous quarter.

Net profit for Q1FY27 was ₹197 crore, translating to a year-on-year increase of 1,870%. On a quarter-on-quarter basis, net profit increased 233.90% from ₹59 crore in Q4FY26. Basic EPS for the quarter was ₹4.03, compared with ₹0.20 in Q1FY26 and ₹1.21 in Q4FY26.

Margin expansion and operating metrics

The company reported an EBITDA margin of 20.8% in Q1FY27. This compared with 13.7% in Q1FY26 and 15.1% in Q4FY26, reflecting the operating leverage in the quarter.

STL also disclosed an optical connectivity attach rate of 16% in Q1FY27, compared with 15% in FY26. While the company did not break out segment-level profitability in the provided details, this attach rate is an important operational indicator because it points to a higher share of value-added connectivity in the overall mix.

Record open order book and revenue visibility

STL said it ended Q1FY27 with a record open order book of ₹18,618 crore. The company has also announced several contracts that extend execution visibility into FY29.

A key development was a multi-year supply agreement through its subsidiary, valued at about USD 1.11 billion (about ₹10,000 crore). The award covers optical connectivity products and is scheduled for execution from FY27 to FY29, with completion planned up to March 2029. The quarter was also described as being highlighted by this product contract and by multiple other hyperscaler orders worth over USD 100 million.

Contract wins: hyperscalers, telecom operators, and international orders

STL’s recent deal flow has included both large hyperscaler supply contracts and optical fibre cable orders.

On August 31, 2026, the company disclosed a three-year long-term supply agreement with a leading international hyperscaler worth about USD 288 million, covering calendar years 2027 to 2029. The agreement provides for purchase orders to be released periodically and includes a possible two-year extension by mutual consent.

Other reported wins include a long-term supply contract valued at USD 210 million for high-density optical fibre cables and a ₹1,760 crore international order for high-density optical fibre cables under a three-year contract. STL also received a multi-year domestic order worth about ₹960 crore from a telecom operator for optical fibre cable supply. Separately, the stock rallied over 15% after it agreed with BSNL for a ₹2,631.14 crore contract.

Balance sheet actions: QIP, cash position, and fundraise approval

STL reported it completed a Qualified Institutions Placement of ₹1,500 crore, and that this enabled it to become net debt-free with a net cash balance of ₹483 crore. In addition, the board approved raising up to ₹2,000 crore via equity shares or other equity-linked instruments.

The company also disclosed it had raised ₹124.58 crore till March 31, 2026 through warrants convertible into equity shares on a preferential basis. Separately, news flow referenced the stock moving on receiving approval for a ₹3,000 crore capital expenditure plan.

Product and certification updates tied to AI data centres

Alongside order announcements, STL reported US certification for indoor optical fibre assemblies designed for AI data centres. It also launched India’s first Hollow Core Fibre cable via regulatory filing. According to the company, the technology enables 46% faster signal transmission through air-filled cores and uses a hybrid architecture combining multiple fibre types.

These product moves are aligned with the set of contracts linked to AI infrastructure and data centre buildouts, particularly in the US market.

Why the quarter matters

The Q1FY27 results combine three signals investors typically track in cable and connectivity names: a step-up in earnings, higher margins, and a larger order book. The scale of the ₹18,618 crore open order book and the multi-year nature of hyperscaler-linked awards extend visibility beyond a single fiscal year, with certain contracts explicitly running through 2029.

At the same time, STL’s fundraising actions and its stated net cash position of ₹483 crore after the ₹1,500 crore QIP change the near-term balance sheet narrative. The additional board approval to raise up to ₹2,000 crore, along with reference to a ₹3,000 crore capex plan, suggests the company is keeping financial flexibility for expansion and execution.

Conclusion

Sterlite Technologies’ Q1FY27 showed a strong rebound in profitability, with net profit at ₹197 crore and revenue at ₹1,910 crore, alongside margin expansion and a record ₹18,618 crore order book. Recent announcements around hyperscaler supply contracts, international cable orders, and product certifications have also strengthened revenue visibility into FY29. The next set of updates to watch will be periodic purchase orders tied to multi-year agreements and any further disclosures on the approved fundraising and capex plans.
