A Real Profit Decline, Financing a Real AI Infrastructure Bet
H1 2025 confirms the revenue softness Q1 2025's coverage first flagged wasn't a one-quarter blip: revenue fell 3.1% YoY to Rp27,109.6 billion, and net income attributable to owners fell 14.6% to Rp2,335.3 billion - a genuine decline this time, not distorted by mismatched one-offs on either side of the comparison. Operating income fell 9.9% on a clean basis. Free cash flow collapsed 68.8% YoY to Rp1,512.3 billion, as capex roughly doubled to Rp8,063.5 billion (+68.0% YoY) while operating cash flow held essentially flat.
The capex surge has a clear, disclosed cause: Indosat's H1 2025 presentation states the company became the first operator in Asia to bring NVIDIA GB200 servers live, delivered as part of an "AI Centre of Excellence" launched in partnership with Indonesia's Komdigi (Ministry of Communication and Digital Affairs), NVIDIA, and Cisco - a direct, concrete follow-through on both June 2024's Capital Markets Day roadmap and Q1 2025's GB200 GPU order. The company discloses year-to-date 2025 capex of US$400 million and reiterates it's on track for US$35 million of net new AI-related revenue in 2025, with contribution starting in Q2 2025. This is real, not aspirational: total debt jumped 30.0% quarter-over-quarter to Rp17,681.5 billion, financing much of the buildout, and net debt/EBITDA rose to 0.49x from Q1's 0.36x as a direct result.
The Prescription
Indosat should now disclose the GB200/AI infrastructure investment as its own line item in future capex breakdowns, rather than folding it into overall capex figures - a reader currently has to infer the AI-specific spend from context (the "US$400 million YTD capex" figure and the debt increase) rather than see it stated as a distinct number. What it should keep doing: being genuinely first-mover and concrete about the AI infrastructure claim ("first in Asia," Komdigi/NVIDIA/Cisco partnership named directly) rather than vague strategic language - this is a real, verifiable claim a reader can track, unlike the strategic-direction-only disclosure H1 2024's Capital Markets Day offered.

| Total Cash | Rp5,174.3B | ~$318.9M | Rp4,569.6B (H1 2024 close) | ✅ +13.2% | ✅ |
Total debt jumped to Rp17,681.5 billion from Q1 2025's Rp13,602.7 billion (+30.0% QoQ), the sharpest single-quarter debt increase this site has tracked for Indosat, reversing the deleveraging trend almost entirely - the increase is directly attributable to the AI-infrastructure capex disclosed this half. Free cash flow's 68.8% decline traces almost entirely to capex (Rp8,063.5 billion for the half, +68.0% YoY) growing far faster than operating cash flow (Rp9,575.8 billion, -0.8% YoY, essentially flat).
H1 2025's profit decline (-14.6%) is genuine, not one-off distorted - and it coincides directly with Indosat's real, disclosed AI-infrastructure investment: NVIDIA GB200 servers the company says went live first in Asia, funded by a 30.0% quarter-over-quarter debt increase and US$400 million of year-to-date capex. See Beyond the Usual below.
Key Operational Metrics
H1 2025's presentation discloses over 20,000 BTS added year-to-date 2025 (network densification continuing alongside the AI buildout), but a numeric subscriber count or blended ARPU figure wasn't available in text-extractable form this half.
Segment Comparison
| Segment | Revenue H1 2025 | Revenue H1 2024 | YoY | Share of Revenue |
|---|---|---|---|---|
| Selular (cellular) | Rp22,749.7B | Rp23,601.1B | ⚠️ -3.6% | 83.9% |
| MIDI (enterprise/data/internet) | Rp3,961.6B | Rp3,916.4B | ✅ +1.2% | 14.6% |
| Telekomunikasi Tetap (fixed) | Rp398.3B | Rp458.9B | ⚠️ -13.2% | 1.5% |
| Total | Rp27,109.6B | Rp27,976.3B | ⚠️ -3.1% | 100% |
Selular
Declined 3.6% cumulatively, deepening from Q1 2025's -2.0% - now clearly a two-quarter trend, not a one-off dip, for the company's core segment.
MIDI
Essentially flat cumulatively (+1.2%), still weak against the 23-35% growth rates shown throughout 2024, though marginally positive versus Q1's -0.5% - the segment most likely to benefit from the AI/GPUaaS buildout hasn't yet shown that benefit in the reported revenue numbers.
Telekomunikasi Tetap
Declined 13.2% cumulatively, its steepest decline in this site's coverage, extending the reversal that began with FY2024's -14.1%.
Beyond the Usual
Indosat Says It Was the First Operator in Asia to Bring NVIDIA GB200 Servers Live
The H1 2025 presentation states Indosat became the first operator in Asia to bring NVIDIA GB200 AI servers live, delivered through an "AI Centre of Excellence" launched with Indonesia's Komdigi, NVIDIA, and Cisco - following directly from Q1 2025's GB200 order, which targeted operational status by Q3 2025 (this half's news suggests it arrived ahead of that timeline). The company also discloses US$400 million of year-to-date 2025 capex and reiterates the US$35 million 2025 net-new-AI-revenue target. Flagged yellow rather than green because this is a real, large capital commitment (visible in the 30.0% QoQ debt increase) whose return on investment hasn't yet materialized in reported segment revenue - MIDI, the segment most likely to capture AI/GPUaaS revenue, grew just 1.2% cumulatively this half.
The Company Launched a Security Operations Center With Cisco, a New Enterprise Business Line
Alongside the AI infrastructure news, the presentation discloses the launch of a Security Operations Center in collaboration with Cisco - a new enterprise/ICT service line consistent with the broader "security, network, cloud, IoT, AI" portfolio June 2024's Capital Markets Day first described.
Net Debt/EBITDA Rose to Its Highest Level Since the Merger, Still From a Low Base
Net debt/EBITDA rose to approximately 0.49x from Q1's 0.36x - the sharpest quarter-over-quarter increase this site has tracked, though still comfortably below the roughly 0.60-0.90x levels seen in 2021-2022's post-merger period. Worth watching whether this stabilizes as the initial AI-infrastructure capex wave completes or continues rising with further investment.
Target Valuation Range
Bottom line: roughly Rp1,470-Rp2,440 fair-value range (bear-to-bull, annualized EV/EBITDA-based) against a Rp2,090 actual close - the stock traded in the upper-middle of that range, suggesting the market is pricing the AI-infrastructure investment as a credible growth driver rather than purely as a leverage risk.

| Bear | AI capex keeps rising without the US$35mn 2025 revenue target materializing | ~2.5x | ~Rp64,275B | ~Rp1,447 |
| Base | AI infrastructure investment stabilizes and begins converting into MIDI/enterprise revenue | ~3.25x | ~Rp83,558B | ~Rp2,199 |
| Bull | GB200 first-mover position and GPUaaS revenue scale faster than guided | ~3.75x | ~Rp96,413B | ~Rp2,440 |
Net debt/EBITDA at ~0.49x remains well within a manageable range even after the sharpest quarterly increase this site has tracked, and the market's willingness to price the stock in the upper half of this range suggests investors are treating the AI-infrastructure bet as credible rather than purely dilutive. No multi-year DCF yet: this is a genuine strategic inflection point (a real capex/debt commitment tied to an unproven new revenue line), and this site would want to see at least one or two quarters of actual AI-related revenue realized before building a standalone projection around it.
