Jakarta, Indonesia – Indosat Ooredoo Hutchison (ISAT), a leading Indonesian telecommunications powerhouse, reported a robust financial year for 2025, not only meeting but significantly exceeding market expectations. The company’s strategic maneuvers and operational efficiency culminated in a formidable net profit of Rp5.5 trillion for the full year, a compelling 12% year-on-year surge, eclipsing consensus estimates by a significant 114%. This impressive trajectory was spearheaded by an exceptional fourth quarter, which saw net profit jump to Rp1.9 trillion, demonstrating an 86% year-on-year and 54% quarter-on-quarter increase.

Operational Excellence Drives Unprecedented ARPU Growth

Indosat’s operational strength shone brightly in 2025, with full-year operating profit holding steady at approximately Rp10.8 trillion, again surpassing consensus by 102%. This stability was underpinned by a 1% year-on-year revenue increase and a commendable 10% year-on-year reduction in operational expenses, despite a 4% rise in cost of revenue. The fourth quarter proved particularly dynamic, with revenues climbing 9% year-on-year and quarter-on-quarter, fueled by a remarkable surge in Average Revenue Per User (ARPU).

ARPU Reaches Post-Merger High, Signals Industry Health

In 4Q25, Indosat’s ARPU ascended to an impressive Rp44,000, marking a substantial 13.1% year-on-year and 10% quarter-on-quarter increase. This figure represents the highest ARPU achieved since the company’s transformative merger in 2022. Management attributes this powerful ARPU growth to several strategic pillars:

• Improved Pricing Discipline: A healthier competitive landscape within the industry.
• Enhanced Customer Experience: Introduction of innovative new services.
• AI-Powered Personalization: Leveraging AI for hyper-personalized offerings, driving greater customer value.

While the subscriber base experienced a slight dip (1.1% year-on-year, 1.4% quarter-on-quarter), the concurrent robust ARPU increase underscores a significant positive shift in market dynamics. This suggests that the fierce pricing competition previously seen in the sector is steadily improving, allowing operators like Indosat to extract more value per user. The company’s leadership remains optimistic, forecasting continued ARPU momentum into 2026.

GPU-as-a-Service: A New Horizon in Digital Infrastructure

Beyond traditional telecom services, Indosat’s ‘Multimedia, Data Communication, and Internet’ (MIDI) segment demonstrated phenomenal growth, with revenues skyrocketing 13% year-on-year and 15% quarter-on-quarter in 4Q25. A key catalyst for this expansion was the successful launch of its GPU-as-a-Service (GPUaaS) business in September 2025. This nascent yet powerful offering contributed US$20 million in revenue in 4Q25 alone. Based on existing contracts, Indosat projects GPUaaS to generate a substantial US$50-60 million in 2026, positioning the company at the vanguard of Indonesia’s burgeoning digital infrastructure demands.

Strategic Future: FiberCo Transaction Unlocks Capital & Growth

Indosat’s forward-looking strategy extends to optimizing its asset base and unlocking new avenues for growth. The company is poised to complete a significant transaction involving the transfer of its fiber optic network for the formation of a new entity, FiberCo, in partnership with Arsari Group and Northstar Group. Indosat anticipates receiving a substantial US$700 million from this transaction in 2Q26/3Q26.

Although Indosat will retain a 45% ownership stake in FiberCo, the structure of this partnership means Indosat will not consolidate FiberCo’s financial performance. However, crucially, Indosat will maintain operational control over FiberCo. Management views this strategic move as a potent catalyst for growth within the fiber business, particularly in the rapidly expanding fiber-to-the-home (FTTH) segment. This move not only injects significant capital but also allows Indosat to participate in the burgeoning demand for high-speed connectivity while focusing its core resources.

With a comprehensive strategy that spans operational excellence, innovative service offerings, and shrewd asset optimization, Indosat is not merely reporting strong numbers; it is actively shaping its future, promising a compelling trajectory for investors and stakeholders alike, as detailed in its latest financial report.
