La Caisse has completed one of the largest recent foreign investments in Indian digital infrastructure, paying approximately ₹121 billion, or C$1.76 billion, for a 24% stake in Altius Telecom Infrastructure Trust (NSE: ALTIUSINVIT).
The transaction gives the Canadian investment group a substantial minority position alongside Brookfield, which remains Altius’ largest investor. Existing investors affiliated with GIC and British Columbia Investment Management Corporation also remain shareholders following completion. Altius owns and operates more than 258,000 telecom towers and sites across India.
The disclosed consideration provides an unusually useful valuation reference. Dividing ₹121 billion by the 24% stake implies an equity value of approximately ₹504 billion, or about ₹50,400 crore, for 100% of Altius on the same transaction-price basis. Using La Caisse’s disclosed Canadian-dollar conversion produces an implied value of roughly C$7.3 billion for the entire platform.
That calculation does not mean Altius itself has been sold for ₹504 billion, nor does it account for potential differences between minority and control valuations. It does, however, show the amount of capital institutional investors are prepared to place behind Indian passive telecom infrastructure at a time when mobile-data usage and 5G network density continue to expand.
Why is La Caisse committing ₹121 billion to an Indian telecom tower platform?
La Caisse has positioned the investment around long-term growth in connectivity rather than a short-term telecommunications cycle. The investor said increasing mobile-data demand and India’s economic expansion require continued investment in the physical infrastructure behind wireless networks.
That infrastructure includes tower structures, power systems and sites on which mobile operators deploy their radio equipment. Tower companies can benefit when operators add new sites, place more equipment on existing sites or increase tenancy as networks become denser.
India gives infrastructure investors an unusually large addressable market. Altius already has a pan-India footprint exceeding 258,000 towers and sites and provides infrastructure used by mobile operators for both 4G and 5G services. The company is also positioning its network for longer-term demand from internet-of-things applications, private enterprise connectivity, edge artificial intelligence and eventually 6G.
For La Caisse, buying into an existing nationwide platform avoids the need to assemble an Indian tower portfolio asset by asset. It also places the investor alongside Brookfield, GIC-linked investors and British Columbia Investment Management Corporation, giving Altius a shareholder base dominated by large long-duration institutional capital.
How did Brookfield build Altius into a platform with more than 258,000 telecom sites?
Altius is itself the product of several large infrastructure transactions.
Its development began with the acquisition of Summit Digitel, which houses tower assets originally transferred from Reliance Jio Infocomm Limited. Brookfield agreed in 2019 to invest ₹252.15 billion into the trust structure associated with those assets. Altius subsequently added Crest Digitel in 2022 and acquired the Indian business of American Tower Corporation in 2024, which was renamed Elevar Digitel Infrastructure Private Limited.
The combination of Summit Digitel, Crest Digitel and Elevar created the current Altius platform. By late 2025, management said the business had more than 314,000 tenancies and had achieved a 28% revenue compound annual growth rate since inception through a combination of contractual escalations, organic expansion and acquisitions.
The scale makes Altius difficult to replicate quickly. New entrants can construct individual towers, but building a nationwide portfolio with hundreds of thousands of sites, customer contracts, operating teams and power infrastructure requires enormous capital and years of execution.
That helps explain why pension funds and infrastructure managers are willing to pay substantial amounts for existing platforms. The competitive advantage is not simply ownership of steel towers but the network of leases, customer relationships and locations attached to them.
What does the ₹121 billion investment suggest about Altius’ underlying valuation?
The implied roughly ₹504 billion equity valuation becomes more interesting when placed beside Altius’ recent operating scale.
Company materials show FY2025 reported operating revenue of approximately ₹195 billion, with that financial year including only about seven months of Elevar operations following the American Tower Corporation India acquisition. On a simple, unadjusted basis, the implied equity valuation from the La Caisse transaction is therefore around 2.6 times FY2025 reported revenue.
That is not a conventional enterprise-value-to-revenue multiple because the ₹504 billion calculation reflects implied equity value rather than enterprise value and does not incorporate Altius’ debt. It also compares a 2026 transaction with a fiscal year that did not include a full 12 months of Elevar. The calculation is useful as a scale reference, not as a directly comparable valuation multiple.
Altius’ capital structure matters because telecom towers are infrastructure assets commonly financed with substantial long-duration debt. Credit-rating disclosures show the trust has carried AAA ratings from major Indian agencies, while its operating entities benefit from long-term customer relationships, including Summit Digitel’s master service arrangement with Reliance Jio Infocomm Limited.
The investment therefore combines growth-market exposure with infrastructure characteristics that large pension and institutional investors typically seek: physical assets, long-duration contracts, recurring cash flows and the possibility of incremental revenue as customers add equipment or tenancies.
Did Altius units react to the La Caisse investment on the Bombay Stock Exchange?
Altius Telecom Infrastructure Trust units are listed on BSE Limited under scrip code 543225, although trading patterns are different from highly liquid ordinary equities. The units closed at ₹172 on September 2, up 2.33% from ₹168.09 in the previous session.
The September 2 level sat close to the upper end of the reported 52-week range of ₹142 to ₹178.20. However, the units had fallen 3.95% on September 1 after closing at ₹175 on August 26, so the latest movement is better viewed as a recovery within a relatively narrow recent trading range rather than evidence that investors suddenly repriced the trust solely because of La Caisse.
The transaction itself nevertheless provides a powerful institutional valuation signal. La Caisse is putting ₹121 billion of capital behind a minority stake even after Altius has already completed several years of acquisition-led expansion.
That suggests the investment thesis is shifting from building the tower platform toward extracting growth from the platform now assembled.
What determines whether La Caisse’s ₹121 billion India tower bet delivers its expected returns?
The key variable is utilisation of the existing network.
India does not necessarily need hundreds of thousands of entirely new macro towers for investors to earn attractive returns. Additional operator tenancies, network densification, small cells, fibre connectivity and new equipment deployed at existing locations can all increase revenue from infrastructure already in place.
The second variable is capital discipline. Altius has grown both organically and through acquisitions, and its ability to balance additional investment with distributions and leverage will determine how much of future operating growth reaches investors.
Competition also remains relevant. India contains other major tower portfolios, including Indus Towers, and mobile operators retain strong bargaining power because a small number of large carriers account for substantial network demand.
Still, La Caisse is entering at a point where Altius has already assembled national scale. The ₹121 billion investment is therefore not principally a bet that India will need telecom towers someday. It is a bet that an existing 258,000-site platform can monetise much more traffic, equipment and connectivity as the country’s digital infrastructure requirements deepen.
The transaction has closed and the valuation signal is now visible. What comes next is the harder part: converting India’s enormous growth in data consumption into sustained returns on one of the world’s largest tower portfolios.
