Indus Towers: Network Expansion Meets a Tough FY23 Reset

Indus Towers closed the year ended March 31, 2023 with a larger nationwide tower network and a clear connection to India’s accelerating 5G rollout. But the financial result was much weaker than the operating footprint suggests. Revenue from operations rose 2.4% year on year to Rs 28,381.8 crore, while EBITDA, excluding other income, fell 34.6% to Rs 9,767.0 crore. Profit after tax fell 68.0% to Rs 2,040.0 crore.

The March quarter was materially better than the December quarter. Quarterly revenue was Rs 6,752.9 crore, down 5.1% from a year earlier but broadly stable sequentially. EBITDA was Rs 3,446.6 crore and the EBITDA margin recovered to 51.0%, from 17.5% in the preceding quarter. Profit after tax was Rs 1,399.1 crore after a loss in the December quarter.

The recovery matters, but it does not erase the full-year weakness. A Rs 492.8 crore impairment of the revenue equalisation reserve for a large customer hurt FY23 earnings. The cash-flow statement also included a Rs 5,307.7 crore net provision for doubtful debts and advances. These items put customer credit quality and collections at the centre of the investment case.

A larger network, but lower yield per site

Indus Towers provides shared passive telecom infrastructure. It owned and operated 192,874 towers at March 2023, up from 185,447 a year earlier. Co-locations rose by 7,040 over the year to 342,831. The company added 3,482 towers and 3,396 co-locations in the March quarter alone.

This expansion gives Indus a substantial national footprint across all 22 Indian telecom circles. Its contracts are also long dated. The average residual service-contract period was 6.28 years at March 2023, while future minimum lease payment receivables under long-term non-cancellable agreements stood at Rs 108,055.4 crore.

Still, the quality of network expansion is as important as the quantity. The average sharing factor, which measures co-locations per tower, fell to 1.78 from 1.81 a year earlier. Sharing revenue per tower per month fell 13.9% year on year to Rs 73,535. More assets were added, but average sharing revenue per site declined.

The revenue split shows the model clearly. Sharing revenue, generated from customers using the tower infrastructure, was Rs 17,431.7 crore in FY23. Energy reimbursements were Rs 10,950.1 crore. Sharing revenue therefore represented about 61% of revenue from operations, while energy reimbursements made up about 39%.

The customer-credit issue reshaped the year

FY23 was not simply a period of slower revenue growth. The company took a Rs 492.8 crore impairment of revenue equalisation reserve related to a large customer. This was classified as an exceptional item and had a direct effect on reported profitability.

The cash-flow statement provides another important data point. It shows a Rs 5,307.7 crore net provision for doubtful debts and advances in FY23. Trade receivables were Rs 4,868.7 crore at March 2023, down from Rs 7,058.6 crore a year earlier, but still material relative to the company’s annual earnings. For a tower company, contracted revenue and long-term agreements are valuable. Yet cash collection remains the practical test of that visibility.

The effect was visible in returns. Return on capital employed before tax fell to 11.0% at March 2023, from 25.7% a year earlier. Return on shareholder equity after tax fell to 9.4% from 33.5%. These declines reflect the pressure on annual earnings rather than a shrinking infrastructure base.

The March quarter provided some relief. Other operating expenses declined sharply from the elevated December-quarter level, helping EBITDA rebound to Rs 3,446.6 crore. But investors would need to distinguish between a quarter-on-quarter recovery and proof of a sustained return to prior margin levels.

5G creates demand, while energy remains a cost challenge

The industry backdrop is constructive for network infrastructure. The presentation said the top two operators had launched 5G in more than 500 cities and planned to complete urban coverage over the following three to six months. It also cited more than 140,000 5G base transceiver stations deployed nationally, with weekly deployment run rates rising through the March quarter.

Customer updates pointed to an even faster rollout. Bharti Airtel said its 5G service was available in 500 cities and expected to cover urban India by September 2023. Reliance Jio said its 5G service was available in more than 2,300 towns and cities and aimed to cover every town by December 2023.

For Indus, this activity can support demand for conventional tower space and for denser products such as smart poles, microsites, fibreized connectivity, feather sites and small cells. The company also sees a future role for infrastructure providers in active network sharing, including shared transport networks and shared radio access networks. These are strategic possibilities, not disclosed revenue commitments.

Energy costs remain central to margins. Power and fuel expense was Rs 10,590.8 crore in FY23, the largest cost line. Indus reported about 80,993 green towers and about 1,496 solar-powered and Solar RESCO sites as of March 2023. It is pursuing electrification, advanced storage, removal of air conditioners and other measures intended to reduce diesel consumption.

The company has also initiated lithium and VRLA battery deployment using an HSBTS switch. An aluminium-air energy-generation solution for high diesel-consumption sites was evaluated for a planned pilot. These measures could reduce operating-cost exposure over time, but the presentation does not quantify expected savings or a rollout schedule.

Cash flow and leverage need close attention

Capital expenditure rose 40.7% to Rs 4,121.0 crore in FY23 as the tower base expanded. At the same time, operating free cash flow fell 71.4% to Rs 2,618.2 crore. Adjusted funds from operations fell 48.0% to Rs 5,876.9 crore, while free cash flow was Rs 1,400.1 crore.

Net debt including lease liabilities was Rs 18,886.9 crore at year-end. This was lower than the Rs 19,470.3 crore at December 2022, but above the Rs 17,093.7 crore reported a year earlier. Net debt including lease liabilities to last-twelve-month EBITDA rose to 1.93 times from 1.14 times. Interest coverage declined to 6.72 times from 9.98 times.

None of these figures suggests an immediate operational break. However, they show why future improvement depends on more than adding towers. Indus needs stronger customer collections, stabilisation in sharing revenue per tower, disciplined capital expenditure and continued energy-cost control to rebuild cash conversion and returns.

The FY23 theme: scale is intact, financial quality needs rebuilding

Indus Towers remains a large national infrastructure platform with long-term contracts, a broad tower base and exposure to 5G-led network investment. The March quarter showed that profitability can recover sharply when unusual operating costs subside.

But FY23 also showed the limits of viewing the business only through tower additions. The customer-related impairment, doubtful-debt provisioning, weaker sharing yield, lower returns and reduced operating free cash flow changed the financial picture. The next phase will be judged by whether 5G deployment converts into higher quality tenancy and collections, not merely more sites. That is the key measure of progress for Indus Towers after a difficult year.
