Indosat Q4 Earnings Call Signals Renewed Growth

PT Indosat Tbk Class B ((PTITF)) has held its Q4 earnings call. Read on for the main highlights of the call.

PT Indosat Tbk Class B’s latest earnings call struck a broadly optimistic tone, with management highlighting a powerful rebound in the final quarter of the year. Strong ARPU recovery, double‑digit EBITDA growth, a landmark fiber monetization deal, and a rock‑solid balance sheet underpinned a constructive outlook despite modest full‑year growth and some one‑off profit supports.

Robust Q4 Revenue and EBITDA Upswing

Q4 marked a clear inflection point, as revenue climbed 9.3% quarter‑on‑quarter while EBITDA jumped 11.6%, outpacing the top line. This operational gearing pushed the EBITDA margin up by 1 percentage point to 47.2%, signaling better cost control and improved profitability exiting the year.

ARPU Rebounds to Post‑Merger High

Cellular ARPU surged 11% quarter‑on‑quarter to IDR 44,000, the highest level since the merger and a key driver of earnings momentum. Management said this improvement continued into February and sees room for further ARPU upside, hinting at a strategy focused on quality subscribers over sheer volume.

Profits Strengthen on Quarterly and Annual Basis

Normalized net profit leapt 51.2% in Q4, underscoring the strength of the year‑end recovery. For the full year 2025, reported net profit rose 12.2% and normalized net profit grew 11.6% year‑on‑year, although these gains came off a softer performance earlier in the year.

AI Scam Protection Supports Loyalty and Monetization

The company showcased its AI‑powered 360‑degree scam and spam protection, claiming 99% efficacy and blocking more than 2 billion malicious attempts. Management argued this “100% protection” for covered users is helping reduce churn and improving customer willingness to pay, feeding into the ARPU recovery.

Neocloud GPU‑as‑a‑Service Builds Early Scale

Neocloud, the GPU‑as‑a‑Service offering, delivered around USD 28 million in revenue in 2025, with roughly USD 20 million of that in Q4 alone. For 2026, contracted revenue stands at USD 50–60 million on multi‑year deals of five years or more, giving the business a recurring, high‑growth digital revenue stream.

FiberCo Monetization Unlocks USD 700 Million

A strategic FiberCo transaction is set to generate about USD 700 million in proceeds between the second and third quarters, while Indosat retains operational control of the assets. Management presented the deal as a key value‑unlock, freeing capital to support FTTH expansion and other growth initiatives without sacrificing network control.

Balance Sheet Strength Provides Strategic Flexibility

Net debt‑to‑EBITDA improved to 0.39x, down 0.1x quarter‑on‑quarter, driven by an 18.9% sequential reduction in net debt and a 1.4% decline year‑on‑year. This low leverage gives the group ample headroom to fund growth, absorb CapEx cycles, and support dividends without straining the balance sheet.

Disciplined CapEx and Expanding Home Broadband

CapEx for 2025 came in at IDR 13.3 trillion, matching guidance, with Q4 spending down 22% quarter‑on‑quarter to IDR 2.54 trillion as network roll‑outs normalized. Home broadband remained a bright spot, adding 24,000 customers for 6.6% quarterly growth, while data traffic climbed 7.6%, signaling rising usage and monetization potential.

Full‑Year Growth Trails Q4 Momentum

Despite the strong finish, full‑year revenue rose just 1.1% and EBITDA 0.8% year‑on‑year, revealing that earlier quarters were comparatively soft. The disconnect between modest annual growth and strong Q4 performance suggests investors should watch whether the recent momentum can be sustained through 2026.

Costs Tick Higher, Adding Volatility

Operating expenses increased 1.4% year‑on‑year and 7.3% quarter‑on‑quarter, reflecting a mix of structural and discretionary costs. Personnel expenses spiked 39% quarter‑on‑quarter on higher variable pay, marketing jumped 16%, and cost of services rose 3% sequentially and 5% year‑on‑year, tied to acquisition, installation, and partnership costs.

Non‑Recurring Gains Boost Reported Profit

Part of the profit surge was driven by one‑offs and investment gains that are unlikely to repeat. The quarter benefited from a substantial IDR 142 billion investment gain and a jump in other operating income from IDR 21 billion in 2024 to IDR 509 billion in 2025, helped by tax reversals and other non‑recurring items.

GPU Revenue Guidance Trimmed on Timing Delays

While Neocloud traction is evident, management trimmed near‑term GPU revenue expectations versus earlier commentary of around USD 75 million. The updated 2026 contracted range of USD 50–60 million reflects supply‑chain disruptions and roughly a one‑quarter slip in deployments, highlighting execution and timing risks.

FiberCo Deconsolidation Creates Margin Uncertainty

The spin‑off of fiber assets may lead to deconsolidation and ongoing service payments to the new FiberCo, adding complexity to reported metrics. Management expects limited impact on revenue but flagged a low single‑digit EBITDA hit, leaving some short‑term uncertainty over margins and accounting treatment.

Subscriber Base Pressures Amid ARPU Focus

Management acknowledged earlier subscriber losses of about half a million users in a prior quarter and continues to work on stabilizing the base. While higher ARPU is positive, the timeline for returning to consistent subscriber growth remains unclear, making volume trends a key metric for investors to monitor.

Cautious Stance Despite Strong Exit to the Year

The company’s 2026 guidance of mid‑ to high‑single‑digit revenue and EBITDA growth appears conservative relative to the robust Q4 uplift. Executives cited macro and market uncertainties as reasons for restraint, hinting that upside is possible if current operational trends persist but declining to bake that into official targets.

CapEx Path Clouded by Neocloud Expansion Needs

Base‑case 2026 CapEx guidance of about IDR 13 trillion excludes Neocloud‑related investments, which will be made only as new GPU contracts are signed. This approach limits upfront risk but also means future CapEx could be lumpy and higher than base levels, depending on how quickly cloud and AI demand scales.

Forward‑Looking Outlook and Capital Allocation Plans

For 2026, management expects mid‑ to high‑single‑digit growth in both revenue and EBITDA, while holding EBITDA margins broadly stable in the high‑40s. CapEx is planned at around IDR 13 trillion, with Neocloud spending added only against new contracts, and the company anticipates around USD 700 million FiberCo inflows, low leverage, and a rising dividend payout ratio that is set to climb toward 70% by 2028.

Indosat’s earnings call painted a picture of a telecom operator exiting the year with clear momentum, stronger profitability, and meaningful strategic optionality. While one‑off gains, cost bumps, and execution risks around FiberCo and Neocloud warrant vigilance, the combination of rising ARPU, digital growth, and balance sheet strength offers an encouraging setup for patient investors.
