Indus Towers: Profit Recovery Meets a Heavy 5G Buildout

Indus Towers entered the December 2023 quarter with a familiar task: build enough infrastructure for India’s rapidly expanding mobile networks while keeping a close watch on cash, energy costs and collections. The result was a sharp recovery in reported profitability, continued network expansion and an improving leverage profile. But it also showed why a tower business cannot be judged on earnings alone.

Consolidated revenue from operations for the quarter ended December 31, 2023 was Rs 7,199 crore, up 6.4% from Rs 6,765 crore a year earlier. EBITDA, excluding other income, rose to Rs 3,622 crore from Rs 1,186 crore. The EBITDA margin recovered to 50.3% from 17.5%. Profit after tax was Rs 1,541 crore, compared with a loss of Rs 708 crore in the prior-year quarter.

The comparison with the previous year is significant but needs context. The December 2022 quarter included an impairment of the revenue equalisation reserve related to a large customer. That charge pushed other expenses to Rs 2,418 crore in that quarter. In the latest quarter, other expenses were Rs 223 crore, including Rs 65 crore of allowances for doubtful receivables and advances. The recovery therefore reflects both underlying operating performance and the absence of that exceptional prior-year burden.

A larger footprint supports the revenue base

Indus Towers provides passive telecom infrastructure to wireless service providers. Its main business is to acquire, build, own, operate and maintain towers and related equipment, then provide access to operators under long-term master service agreements. The company operates across all 22 telecom circles in India.

The physical network expanded materially in the December quarter. Indus ended the period with 211,775 macro towers and 360,679 macro co-locations. It added 7,563 macro towers and 7,217 macro co-locations during the quarter. Lean co-locations, which are used for targeted coverage and network densification, increased by 1,351 to 9,994.

This buildout is taking place alongside a rapid 5G rollout in India. The presentation noted that almost 400,000 5G Base Transceiver Stations had been deployed nationally, with weekly deployment running above 7,000 in November 2023. That is an important industry backdrop for Indus. New radio equipment and denser networks require sites, power systems and related infrastructure.

Still, the operating data contains a caution. The average sharing factor declined to 1.72 from 1.80 a year earlier. The closing sharing factor declined to 1.70 from 1.79. The sharing factor measures co-locations per tower. A lower figure means fewer operator tenancies, on average, at each tower. That can reduce the revenue productivity of the installed base even as total towers and co-locations grow.

Sharing revenue per tower per month was Rs 71,166, down 3.0% year on year. Sharing revenue per sharing operator per month was Rs 41,454, up 1.5%. In short, Indus is growing its network and total sharing revenue, but it must also improve or stabilise tenant density to maximise returns on the growing asset base.

Energy remains the key operating variable

Power and fuel was Indus Towers’ largest operating cost at Rs 2,795.6 crore in the quarter. It represented 78% of operating expenses. Energy reimbursements were Rs 2,719.5 crore, or 38% of revenue. This makes energy management central to both service delivery and profitability.

The company is pursuing several measures to reduce diesel use and improve energy efficiency. It had about 6,665 solar-powered sites in operation at December 31, 2023, and about 77,099 low-diesel-consumption sites. It is also converting indoor sites to outdoor configurations where practical, reducing use of air conditioning, using high-efficiency power systems for new tower deployments and improving electrification.

Indus has begun deploying a combination of lithium and valve-regulated lead-acid batteries using a hot swappable battery transfer switch. It has also evaluated an aluminium-air energy-generation solution for high diesel-consumption sites and planned a pilot deployment. These initiatives are not presented with quantified savings targets. But the direction is clear: reduce fuel dependence, lower emissions and protect the cost base from increases in power and diesel prices.

The December quarter showed modest sequential progress in energy efficiency. Energy cost per tower per month was Rs 44,803, down from Rs 47,295 in September 2023. Energy cost per co-location per month was Rs 26,098, down from Rs 27,142. These figures can move with site mix, energy prices and network activity, so they should be tracked over several quarters rather than read as a final trend.

Cash flow is the trade-off for expansion

The company’s earnings recovery did not translate directly into operating free cash flow because it is investing heavily in network expansion. Capital expenditure was Rs 2,652.8 crore during the quarter, compared with Rs 1,036.9 crore a year earlier. Operating free cash flow was Rs 162.8 crore, although adjusted funds from operations were Rs 2,504.5 crore.

The difference matters. Indus defines operating free cash flow as adjusted EBITDA after lease-liability repayment and capital expenditure. It is therefore a useful measure of how much cash remains after the investment needed to extend the network. For the first nine months of FY24, capital expenditure was Rs 7,155.9 crore and operating free cash flow was Rs 1,095.8 crore.

Free cash flow was Rs 870.1 crore in the December quarter. Yet cumulative free cash flow for the first nine months was Rs 351.1 crore, versus Rs 704 crore in the comparable prior-year period. The company is building infrastructure for customer demand, but that investment keeps cash generation more variable than the EBITDA margin alone suggests.

Balance-sheet metrics improved in the quarter. Net debt including lease liabilities fell to Rs 19,819.9 crore from Rs 20,353.7 crore at September 2023. Net debt to last-twelve-month EBITDA improved to 1.41 times from 1.75 times. Interest coverage improved to 14.87 times from 9.01 times. Net finance cost was only Rs 10.7 crore in the quarter, helped by Rs 502.8 crore of finance income.

However, the business remains lease-intensive. Total debt including lease liabilities was Rs 19,960.7 crore, and lease obligations were Rs 15,239.6 crore. This is inherent in the site-leasing model, but it means investors should assess both reported debt and lease commitments when tracking leverage.

Revenue visibility is meaningful, but collections need attention

A key support for the Indus model is the duration of its contracts. The weighted average remaining life of service contracts was 6.32 years at December 31, 2023. Future minimum lease payment receivables were Rs 104,610.5 crore. The master service agreements are long-term contracts, include annual escalation clauses and are designed to offer broadly uniform terms to service providers.

That contract base provides visibility, but it does not make credit risk disappear. Trade receivables were Rs 6,018 crore at December 2023, up from Rs 4,868.7 crore at March 2023. The company recorded Rs 64.9 crore of doubtful-receivable and advance allowances in the quarter. Given the impairment recorded in the prior-year period for a large customer, receivable collection remains an item that needs sustained monitoring.

The December quarter was therefore a constructive one for Indus Towers. Revenue grew, profitability normalised, leverage metrics improved and the company expanded its national network at a fast pace. The main questions are not about whether 5G needs infrastructure. It does. The harder questions concern how quickly the enlarged tower base can regain sharing density, how much cash expansion will absorb, and whether energy and collection risks remain controlled.

Indus Towers enters the next phase with a larger footprint, long-dated contracts and a clear focus on energy efficiency. The company’s ability to turn that scale into durable free cash flow will be the most important measure of execution.
