There is a particular kind of market structure that rewards patient capital and frustrates everyone else. It is the kind where the incumbent is so deeply entrenched that competition functions not as a genuine threat to the leader but as a persistent pressure on the challenger's margins, where the number two operator must spend aggressively simply to hold its position, and where the regulator's primary concern is ensuring the infrastructure gets built rather than engineering a dramatic redistribution of subscribers. Saudi Arabia's telecommunications sector is precisely this kind of market, and understanding its internal geometry is more analytically useful than reading any single earnings release in isolation.

The Mobily STC market share dynamic is the most instructive starting point.

As of Q1 2025, stc holds approximately 44 percent of the Saudi mobile market and over 70 percent of fixed-line broadband, underpinning its incumbent status in the Kingdom's telecom landscape.

Mobily commands roughly 28 percent of the mobile market, focusing on 5G quality and loyalty.

In fixed broadband specifically, Mobily is the second-largest provider with around 600,000 subscribers, representing 19.4 percent of the market as of December 2024.

These are not the numbers of a market in competitive flux. They are the numbers of a settled oligopoly, and the analytical question worth asking is not whether the gap will close dramatically but what each operator does with the structural position it already occupies.

The answer, it turns out, is quite different for each of them.

Mobily reported an 11.55 percent increase in profit to SAR 3.47 billion in 2025, up from SAR 3.1 billion in 2024, supported by revenue growth across all business segments and an expanding customer base.

That is a meaningful acceleration for a company that spent several years navigating a difficult balance sheet restructuring. The mechanism behind it is worth examining carefully.

Net profit surged 25.6 percent year over year to SAR 830 million in Q2 2025, driven by an 8.1 percent revenue increase and a 37.8 percent EBITDA margin, with a capital expenditure strategy of SAR 2.697 billion in H1 2025 funding infrastructure projects including the Red Sea subsea cable and 5G spectrum licenses.

Mobily is, in essence, buying its way toward a stronger competitive position in the segments where scale matters most: enterprise wholesale, fixed wireless access, and international connectivity.

💡 Insight

For stc, the strategic response to this environment has been to move beyond the definition of a mobile operator entirely..

That capital expenditure commitment is striking in its own right.

The company recorded SAR 2.13 billion in capital expenditure during Q1 2025 alone, an increase of 850 percent year over year, with spending focused on expanding 5G networks, enhancing spectrum capacity, building new data centers valued at more than 906 million dollars, and strengthening subsea connectivity through projects including Africa 1 and the Saudi Egypt cable system.

For investors in Saudi telecom sector stocks, this level of capital deployment raises the obvious question of return timing. Infrastructure of this kind does not generate revenue on the quarter it is commissioned. The investment thesis for Mobily is therefore structurally a medium-term one, premised on the belief that wholesale digital services and enterprise connectivity will generate the ARPU uplift that consumer mobile, in a saturated market, cannot.

Saturation is the word that deserves more analytical weight than it typically receives in sector commentary.

Mobile connections surpass 116 percent of the population, making incremental subscriber additions a zero-sum fight, while stc posted a 5.2 percent profit decline in Q1 2024 despite higher revenue, illustrating margin compression in mature markets, with operators now focused on upselling premium services rather than chasing new lines.

The consumer revenue story in Saudi Arabia is therefore not a volume story. It is an ARPU story.

Mobile data services revenue is forecast to grow at a strong CAGR of 6.6 percent, supported by higher ARPU from premium 5G plans.

The operators that win this particular contest are those that can migrate their existing subscriber bases onto higher-value plans, not those that acquire the most new SIM cards.

This is where the Vision 2030 digital infrastructure dimension becomes analytically substantive rather than merely rhetorical.

Saudi Arabia has been leading the charge in digital infrastructure investment as part of its broader strategy to reduce economic dependence on hydrocarbons, emerging as one of the most dynamic and rapidly growing markets for fixed wireless access, driven by extensive 5G network deployments, unprecedented spectrum availability, and strong government support.

The government's role here is not simply that of a regulator setting rules. It is the role of a structural demand creator, commissioning the connectivity requirements of NEOM, the Red Sea Development, and a network of smart city projects that require enterprise-grade infrastructure at scale.

Saudi Arabia's Vision 2030 diversification push is accelerating, with non-oil GDP expected to grow at 3.3 percent in 2025 and 4.3 percent in 2026, driven by tech, tourism, and infrastructure projects, with these initiatives relying heavily on robust digital infrastructure and creating a virtuous cycle for telecom firms.

For stc, the strategic response to this environment has been to move beyond the definition of a mobile operator entirely.

The commercial launch of stc Bank in 2025 positions telecom-fintech convergence as a major revenue growth vector, offering bundled digital financial and connectivity services to consumers and SMEs.

stc reported 2024 revenues of SAR 77.3 billion with projections for 5 to 8 percent revenue growth in 2025 as enterprise and digital services scale.

The tower infrastructure angle adds another layer of structural interest.

The Public Investment Fund agreed to buy a 51 percent stake in Telecommunications Towers Company TAWAL from stc Group, with PIF and stc combining TAWAL and Golden Lattice Investment Company to set up a newly formed company with around 30,000 mobile tower sites.

The monetization of passive infrastructure through a PIF-backed vehicle is a capital recycling move of considerable elegance, freeing stc's balance sheet while keeping the strategic relationship with the Kingdom's sovereign wealth architecture intact.

The regional comparison sharpens the picture further.

stc Group has emerged as the largest listed telecom operator in the Middle East and North Africa with a market capitalization of $57.7 billion, placing it ahead of UAE's e&, Mobily, Qatar's Ooredoo Group, and Emirates Integrated Telecommunications.

An e& earnings analysis would show a company pursuing a similar diversification logic across the UAE and internationally, but operating in a different regulatory environment and at a different stage of its digital services transition. The GCC telecom sector as a whole is converging on the same strategic conclusion: that connectivity revenues alone, in markets where penetration is already saturated, cannot sustain the growth multiples that listed companies require. The digital services layer is not optional. It is the next competitive frontier.

Companies listed on the Saudi Exchange posted a 3.8 percent increase in total revenue, exceeding SAR 108.4 billion in 2025, with the performance reflecting continued customer growth and an expanding portfolio of digital solutions, underscoring the sector's central role in advancing Vision 2030.

That top-line growth against a backdrop of aggregate profit pressure tells the story with unusual clarity. The sector is investing heavily, and the returns on that investment will arrive unevenly and on a timeline that requires analytical patience. The Mobily STC market share gap is unlikely to close dramatically. What will change, and what is already changing, is the quality and composition of the revenue that each operator extracts from the position it holds. That is the real story inside
