SIFY Q4 2025: Data Center Backlog Jumps 81MW, CapEx Set to Rise Sharply
SIFY’s data center backlog surged with 81 megawatts contracted for FY26 delivery, setting up a significant revenue-generating capacity ramp. Management signaled sharply higher CapEx as the company aims to nearly double revenue-generating capacity, while regulatory tailwinds and customer demand support an aggressive expansion agenda. Execution focus is shifting to monetization and margin improvement, with digital services still lagging and requiring turnaround investment.
Summary
- Backlog-Driven Growth: 81MW of new data center contracts point to accelerated near-term expansion.
- CapEx Escalation: Capital outlays will rise significantly as SIFY targets a near doubling of revenue-generating capacity.
- Margin Watchpoint: Digital services remain pressured, but management expects gradual improvement and eventual breakeven.
Performance Analysis
SIFY’s revenue mix remains evenly split between network services and data center services, each contributing 39% of total revenue, with digital services at 22%. Network services grew 12% year-over-year, while data center services posted a 23% increase, reflecting robust demand and capacity additions. In contrast, digital services revenue declined by 2%, and segment results dropped 67%, highlighting a clear drag on consolidated margin performance.
EBITDA rose 31% year-over-year, but the company reported a loss before and after tax, driven by higher expenses including a one-time charge related to convertible debentures. CapEx reached INR 13,282 million, with management guiding for a “significantly higher” figure in FY26 as new data center builds accelerate. The data center subsidiary sold 17MW during the year, bringing cumulative sold capacity to 129MW, while the contracted 81MW backlog underpins the growth trajectory for the next several quarters.
- Segment Divergence: Network and data center units delivered robust growth, while digital services remain a margin headwind.
- Cash Position: Year-end cash of INR 5,071 million provides liquidity for expansion, but rising CapEx will test balance sheet discipline.
- Backlog Visibility: 81MW data center backlog offers near-term revenue and utilization clarity, supporting forward guidance.
Operational metrics show strong momentum in network expansion, with 1,224 fiber nodes (+8% YoY) and over 10,000 SD-WAN points deployed nationwide, reinforcing SIFY’s integrated infrastructure positioning.

Strategic Positioning
1. Data Center Scale-Up
SIFY’s data center business is the primary engine of growth, with 129MW revenue-generating capacity and a contracted 81MW backlog for FY26. Design capacity stands at 188MW across 14 live facilities, and management plans to nearly double revenue-generating capacity this year, underpinned by robust customer demand and regulatory incentives.
2. Network Services Expansion
Network services, which include fiber connectivity and SD-WAN, continue to grow at low double-digit rates. The segment’s 8% node count increase and expanded SD-WAN footprint demonstrate SIFY’s ability to leverage its backbone to support both data center tenants and external clients, reinforcing its integrated digital infrastructure model.
3. Digital Services Turnaround
Digital services remain a weak spot, with declining revenue and sharply lower segment results. Management is investing in talent and capability, especially around AI-related infrastructure, but breakeven remains a two-year target. This segment’s recovery is critical for margin improvement and diversification beyond infrastructure services.
4. Regulatory and Policy Tailwinds
Recent government initiatives, including a 20-year tax holiday for foreign cloud providers using Indian data centers, are expected to stimulate demand and attract global hyperscalers. SIFY’s active engagement with these customers positions it to benefit from policy-driven growth.
5. IPO and Capital Structure Moves
The planned IPO of SIFY’s data center subsidiary, CP Infinity Spaces, is approved and sized at INR 3,700 crore (INR 2,500 crore primary, INR 1,200 crore offer for sale). Timing will be market-dependent, but the proceeds are earmarked for expansion and partial partner exit, providing additional capital for growth.
Key Considerations
SIFY’s quarter marks a critical inflection point as the company leans into data center-led growth while tackling operational challenges in digital services. Investors should weigh the sustainability of infrastructure demand, execution risk in scaling, and the path to digital services profitability.
Key Considerations:
- Backlog Monetization: Timely delivery and ramp-up of the 81MW backlog will be key to sustaining revenue growth and utilization rates.
- CapEx Discipline: Significantly higher CapEx raises questions about funding mix, return on investment, and cash flow management.
- Margin Recovery: Digital services must move toward breakeven to support consolidated margin expansion and reduce earnings volatility.
- Policy Leverage: Regulatory incentives could accelerate foreign cloud adoption, but execution and competition will determine share capture.
Risks
Execution risk is rising as SIFY undertakes a near doubling of revenue-generating data center capacity, with large CapEx commitments and delivery timelines. Digital services underperformance remains a margin drag, and any delays in backlog conversion or cost overruns could pressure financials. Market timing for the data center subsidiary IPO is uncertain, and regulatory or geopolitical shifts could impact both demand and capital access.
Forward Outlook
For Q1 FY26, SIFY expects:
- Significant progress on data center backlog delivery, with phased commissioning of contracted capacity.
- CapEx to rise meaningfully as new builds and expansions accelerate.
For full-year FY26, management guided:
- Doubling of revenue-generating data center capacity, with design capacity also increasing.
- Continued double-digit growth in network services and gradual improvement in digital services margins.
Management highlighted several factors that will shape execution:
- Strong policy support and customer demand in India’s digital infrastructure sector.
- Focus on cost competitiveness and cash flow optimization amid rising investment needs.
Takeaways
SIFY’s strategic pivot toward large-scale data center growth is backed by a robust contracted backlog and favorable regulatory trends, but the company must execute flawlessly on delivery and margin improvement. The digital services turnaround remains a key lever for future upside.
- Data Center Execution: The 81MW backlog and planned capacity doubling are central to SIFY’s growth thesis, but delivery pace and utilization will be closely watched.
- Margin Inflection Needed: Digital services must move toward breakeven to unlock full earnings potential and reduce reliance on infrastructure margins.
- IPO and Funding: The CP Infinity Spaces IPO could provide a capital boost, but timing and valuation will depend on market conditions and execution milestones.
Conclusion
SIFY enters FY26 with strong backlog visibility and a clear data center-led growth agenda, but must deliver on execution and margin improvement to realize its full potential. The path forward hinges on converting backlog, managing higher CapEx, and turning around digital services performance.
Industry Read-Through
SIFY’s results underscore a broader surge in Indian data center demand, driven by cloud adoption, regulatory incentives, and global hyperscaler interest. Rising CapEx and backlog visibility are becoming industry norms, and players with integrated network and data center footprints are best positioned to capture share. Digital services margin pressure is a common challenge across the sector, highlighting the need for scale, talent, and differentiated offerings. Policy tailwinds and geopolitical shifts are likely to accelerate India’s emergence as a global data center hub, with implications for both domestic and international infrastructure providers.
