Report overview

Telecom Normalization and AI Data Centers: Two Axes Under Test

Earnings power that collapsed after the 2025 security breach rebounded quickly in the first half of 2026, while AI data centers emerged as the fastest-growing part of the company, redefining what kind of stock this telecom operator is.

1
Full-year 2025 operating profit was KRW 1.073 trillion with a 6.3% operating margin, down sharply from the 9-10% range of 2022-2024; however, quarterly operating profit of KRW 537.6 billion in Q1 2026 and KRW 566.0 billion in Q2 2026 already exceeded the entire prior-year figure in just two quarters.
2
The company said Q2 2026 AI data center revenue reached KRW 136.2 billion, up 92.5% year on year, the fastest-growing area in its portfolio.
3
In July 2026 the board approved the creation of SK Hyper, a wholly owned unit dedicated to AI data center business development, with up to KRW 750 billion of equity injections through 2030, of which KRW 330 billion is the first tranche.
4
The core mobile business has not fully recovered: Q2 2026 mobile revenue was KRW 2.5634 trillion, down 1.9% year on year, and handset market share remains in the 39% range, below the 40% line.
5
After skipping dividends in Q3 and Q4 of 2025, the company declared quarterly dividends of KRW 830 per share in both Q1 and Q2 of 2026, and a March shareholder meeting approved a capital reserve reduction intended to enable tax-exempt dividends.

Business structure

SK Telecom is Korea's largest mobile operator, and wireless service remains the center of gravity for its results.

According to the company, Q2 2026 mobile revenue was KRW 2.5634 trillion, down 1.9% year on year, while 5G subscribers rose from 17.80 million in Q1 to 18.00 million in Q2 and handset subscribers edged up from 21.96 million to 21.97 million (IT Daily, August 2026).

Fixed-line, media and data center operations sit at subsidiary SK Broadband, which on a standalone basis posted Q1 2026 revenue of KRW 1.1498 trillion and operating profit of KRW 116.6 billion, with 7.311 million broadband and 6.75 million IPTV subscribers (TechM, May 2026).

In the same quarter, enterprise revenue was KRW 274.7 billion and AI services for businesses and consumers only KRW 45.0 billion, still small in scale.

The growth engine is shifting to AI infrastructure: AI data center revenue was KRW 131.4 billion in Q1 2026, up 89.3% year on year, followed by KRW 136.2 billion in Q2, up 92.5%.

The customer base is splitting into a domestic retail telecom franchise and an AI infrastructure business selling data center capacity and GPU-as-a-service to global hyperscalers and Korean enterprises.

The competitive structure is an oligopoly of SK Telecom, KT and LG Uplus, where pricing freedom is limited while competition increasingly runs through investment scale. In July 2026 the company consolidated its 5G and LTE tariffs into two simplified tiers, Best and Lite.

On a standalone basis it reported Q2 2026 revenue of KRW 3.1170 trillion and operating profit of KRW 427.7 billion, indicating a rising contribution from subsidiaries within the consolidated numbers.

Earnings analysis

From 2022 to 2024 consolidated revenue rose gradually from KRW 17.3050 trillion to KRW 17.6085 trillion and KRW 17.9406 trillion, while operating profit improved from KRW 1.6121 trillion to KRW 1.7532 trillion and KRW 1.8234 trillion, lifting the operating margin from 9.3% to 10.0% and then 10.2%.

In 2025, however, revenue fell to KRW 17.0992 trillion, operating profit dropped to KRW 1.0732 trillion for a 6.3% margin, and net profit attributable to owners was only KRW 408.4 billion.

The quarterly path shows exactly where the damage concentrated: operating profit fell from KRW 338.3 billion in Q2 2025 to KRW 48.4 billion in Q3, when owners' net result swung to a loss of KRW 158.2 billion, and Q4 operating profit was still just KRW 119.1 billion.

That reflects one-off customer compensation costs and sales restrictions following the USIM data breach, including fee waivers, membership benefits and cancellation-penalty exemptions; in its Q2 2026 release the company noted a base effect from the prior year's temporary spending.

Recovery followed in 2026, with Q1 operating profit of KRW 537.6 billion and owners' net profit of KRW 322.4 billion, then Q2 operating profit of KRW 566.0 billion and owners' net profit of KRW 470.6 billion, so first-half operating profit alone already surpassed the full-year 2025 figure.

Revenue barely moved, at KRW 4.3923 trillion in Q1 2026 and KRW 4.3591 trillion in Q2, showing a structure in which data center growth and cost control offset declining mobile revenue.

Cash generation weakened, with operating cash flow of KRW 5.1593 trillion in 2022, KRW 4.9472 trillion in 2023 and KRW 5.0873 trillion in 2024 falling to KRW 3.9238 trillion in 2025.

On the other hand the debt-to-equity ratio declined from 158.0% in 2024 to 132.4% in 2025 and owners' equity rose from KRW 11.6986 trillion to KRW 12.8631 trillion, a shift consistent with the absence of Q3 and Q4 2025 dividends reducing cash outflow during a period of depressed profits.

Industry analysis

Korea's mobile market is mature, so subscriber additions no longer translate readily into revenue growth. In Q2 2026, SK Telecom's mobile revenue fell 1.9% year on year while KT's wireless revenue of KRW 1.7497 trillion fell 1.8%, leaving all three carriers with stagnant wireless lines (IT Daily, August 2026).

Growth is instead coming from new businesses such as AI data centers, shifting the axis of competition from network speed and tariffs toward AI infrastructure and secured electricity. The bottleneck in AI data centers is power, not buildings.

One industry analysis noted that simply confirming whether the state utility can supply power to a data center takes close to a year, that new restrictions on additional supply in the capital region have been introduced, and that lead times for extra-high-voltage transformers and gas turbines have stretched to two or three times prior norms (e-Focus, July 2026).

As a result, the ability to secure sites and substations in advance has itself become a competitive asset.

On market share, SK Telecom fell below the 40% line after the 2025 USIM breach, standing at 39.02% in January 2026 and around 39.09% in the first quarter, with a partial reversal helped by KT's cancellation-fee waiver period.

Regulation is another variable: research firm Mordor Intelligence noted that a law revised in March 2026 obliges carriers to guide customers to optimal plans based on usage patterns, effective from October 2026.

Overall, with telecom serving as a defensive cash flow source and AI infrastructure as the growth option, the industry is entering a more capital-intensive phase.

Outlook

The most concrete plan the company has laid out is its AI data center roadmap.

On July 23, 2026, the board approved the establishment of SK Hyper, a wholly owned business development company, along with total equity injections of KRW 750 billion through 2030, of which KRW 330 billion goes in first and the remaining KRW 420 billion will be staged according to project progress.

SK Hyper will handle site acquisition, substation construction and operation, global customer acquisition and commercialization, with a first-phase target of progressively opening 5GW of capacity in 2029 and an ambition to expand to 15GW by 2035 depending on market demand.

Geographically it plans a gigawatt-class cluster in Ulsan first, then additional hubs in the Chungcheong and southwestern regions; the Ulsan data center pursued with Amazon Web Services has been reported to target roughly 40MW in a first phase by November 2027 and completion at 103MW by February 2029 (Yonhap News).

In the core telecom business, customer-value moves continue, including the July 2026 unified tariff launch and a membership revamp, and CEO Jung Jae-heon said after the March 2026 annual shareholder meeting that he aims to restore market share to around 40% by year-end.

CFO Park Jong-seok said at the Q2 2026 announcement that the first half was used to consolidate fundamentals on stable telecom earnings while laying the groundwork for rapid AI data center expansion.

On shareholder returns, a policy of distributing at least 50% of consolidated adjusted net profit applies for 2024 through 2026, and the company said the capital reserve reduction approved in March 2026 could be used as a dividend source as early as the year-end dividend once the 2026 financial statements are finalized.

The key things to follow are therefore the pace at which AI data center capacity actually comes online and the sequencing between heavy investment and dividend funding.

Profit-based multiples require careful reading. The trailing four-quarter window still contains Q3 and Q4 of 2025, when breach-related costs were concentrated, so the current earnings-based multiple sits well above the single-digit band in which Korea's three carriers have typically traded.

Conversely, if quarterly profits hold near first-half 2026 levels, the same multiple mechanically compresses, which makes the durability of quarterly earnings more important than the absolute level of the ratio.

Against net assets, the shares trade at a premium to the roughly one-times level long common in the telecom sector, and one market interpretation is that this premium reflects AI infrastructure expectations rather than telecom cash flows.

Indeed, Shinhan Investment Corp. wrote in a report covered in May 2026 that investors' view of the company had shifted from a dividend and defensive name to an AI-related name, and analyst Kim A-ram said in the same coverage that a meaningful portion of the market capitalization is estimated to reflect the value of its Anthropic stake.

On dividends, the missed payouts in Q3 and Q4 of 2025 leave the trailing twelve-month dividend metric below what has typically been expected from the three carriers, and the resumption of quarterly payouts plus any use of the tax-exempt dividend source will determine its direction.

In short, normalization of telecom profits and expectations for AI data centers are priced together, so the same metrics read differently depending on which axis an investor anchors to.

Bull factors

Profit normalization as one-off costs roll off

Operating profit of just KRW 48.4 billion in Q3 2025 and KRW 119.1 billion in Q4 reflected the overlap of breach-related compensation and sales restrictions. Recovery to KRW 537.6 billion in Q1 2026 and KRW 566.0 billion in Q2 pushed first-half operating profit above the entire 2025 total.

The company itself cited a base effect from the prior year's temporary spending in its Q2 release. With revenue barely growing while profit jumped, the source of margin improvement is clearly the cost structure.

AI data center revenue nearly doubling

AI data center revenue of KRW 131.4 billion in Q1 2026, up 89.3% year on year, and KRW 136.2 billion in Q2, up 92.5%, makes it the company's fastest-growing segment. Its share of consolidated revenue is still small, but with capacity coming online there is room for high growth rates to persist.

Management said its GPU subscription business is now on track, and the Ulsan project follows the Gasan facility. As the only growth axis offsetting stagnant telecom revenue, its strategic weight is large.

Shareholder return framework being rebuilt

After confidence in dividends was shaken by the skipped Q3 and Q4 2025 payouts, the company declared quarterly dividends of KRW 830 per share in both Q1 and Q2 of 2026.

A March 2026 shareholder meeting approved a capital reserve reduction to enable tax-exempt dividends, and the company said that source could be used as early as the year-end dividend once the 2026 statements are finalized.

Daishin Securities analyst Kim Hoi-jae was quoted in March 2026 as saying it offers the highest dividend reinvestment yield among the three carriers. The current policy is to return at least 50% of consolidated adjusted net profit for 2024 through 2026.

Bear factors

Wireless revenue and share have yet to recover

Q2 2026 mobile revenue fell 1.9% year on year to KRW 2.5634 trillion, declining even as 5G and handset subscribers increased. Handset share stood at 39.02% in January 2026 and about 39.09% in the first quarter, below the 40% line.

CEO Jung Jae-heon has set a goal of restoring 40% by year-end, but press coverage also noted that recovery may take time. Ramping marketing to win share back would in turn raise cost pressure.

AI data centers demand heavy capital and time

The KRW 750 billion of injections into SK Hyper through 2030 is largely seed money for early business development and power infrastructure, and one analysis noted that actual construction will require project finance and outside investors (Insight Korea, July 2026).

Time needed for grid connection and permits, plus delivery delays for critical equipment such as extra-high-voltage transformers, are schedule risks. Targets of 5GW by 2029 and 15GW by 2035 are long-dated, so slippage at intermediate stages could push out the earnings contribution. The Ulsan project's first phase has been reported for the second half of 2027, limiting near-term contribution.

Shrinking cash flow and dividend policy uncertainty

Operating cash flow fell from KRW 5.0873 trillion in 2024 to KRW 3.9238 trillion in 2025, while the operating margin slipped from 10.2% to 6.3%. With large AI infrastructure investment and dividend funding both required, the priority given to each is the key question.

The current shareholder return policy runs only through 2026, so the shape of the next policy remains to be confirmed. Hana Securities analyst Kim Hong-sik noted in a November 2025 report that confidence in dividends was shaken after the Q3 2025 payout was suspended.

Risk factors

Security and regulatory risk

The April 2025 USIM data leak was recorded as the largest personal data breach in Korean telecom history, and the joint public-private investigation pointed to attacks dating back to 2021 and inadequate remediation by the company.

Class actions, follow-up sanctions and heavier information security spending may continue. The company announced a KRW 700 billion information security overhaul over five years, an additional largely fixed cost.

If a similar incident recurs, the structural vulnerability of simultaneous subscriber losses and compensation costs remains.

Investment and balance sheet risk

The debt-to-equity ratio declined from 157.6% in 2022, 146.3% in 2023 and 158.0% in 2024 to 132.4% in 2025, yet total liabilities in 2025 still stood at KRW 17.1525 trillion.

AI data centers require front-loaded spending on power, land and equipment, so project-level financing is likely to accompany direct equity injections. Higher funding costs or project delays could push back payback timing. The balance between dividend capacity and investment capacity could be strained in the process.

Competition and policy risk

Korea's telecom market is a three-way oligopoly with limited pricing freedom, and tariff cuts and consumer protection policies affect revenue directly.

Mordor Intelligence noted that under a law revised in March 2026, an obligation to guide customers to optimal plans based on usage patterns takes effect in October 2026, a variable that could affect revenue per subscriber alongside tariff simplification.

If the battle for market share reignites, higher marketing costs could pressure operating margins. In AI data centers, rivals, cloud providers and internet platforms are all entering, intensifying competition for contracts.

What to watch next

October 2026
The obligation to guide customers to optimal plans based on usage patterns is due to take effect under the law revised in March 2026. Combined with the July tariff consolidation, its effect on revenue per subscriber and tariff mix warrants monitoring.
Early November 2026
Q3 2026 results and the Q3 dividend decision. Given that the Q3 2025 payout was skipped, continuity of the KRW 830 quarterly dividend, the year-on-year direction of mobile revenue, and whether AI data center growth rates hold are the key items.
December 2026 to January 2027
Year-end handset market share via the Ministry of Science and ICT wireless statistics. Whether the CEO's goal of restoring 40% by year-end is met should be read alongside the impact of marketing spending on Q4 profit.
First quarter of 2027
Finalization of full-year 2026 results and the year-end dividend decision. Points to verify are whether the tax-exempt dividend funded by the capital reserve reduction is actually executed, and whether a new shareholder return policy is announced to succeed the current one ending in 2026.
Second half of 2027
The scheduled first-phase start-up of the Ulsan AI data center pursued with Amazon Web Services, reported at roughly 40MW by November 2027. The pace of SK Hyper's remaining capital injections and progress on securing sites and power in the Chungcheong and southwestern regions are related indicators to track.

Overall view

SK Telecom's current situation requires watching two different clocks at once. The short clock is the return of the core telecom business, whose operating profit had fallen to KRW 1.073 trillion in 2025 with a 6.3% margin after the USIM data breach, to KRW 537.6 billion in Q1 2026 and KRW 566.0 billion in Q2.

The long clock is AI data centers aiming at 5GW in 2029 and 15GW by 2035. On the short clock, a profit surge with almost no revenue growth shows how large the cost base effect was, while also exposing the limitation that mobile revenue still declined year on year.

On the long clock, verifiable milestones now exist, such as the creation of SK Hyper with KRW 750 billion of injections and the Ulsan project schedule, yet the industry-wide bottlenecks of power procurement and permitting remain.

Shareholder returns have a direction again through the resumption of quarterly dividends and the creation of a tax-exempt dividend source, but since the current policy runs only to 2026, the content of the next one is still open.

Valuation metrics blend past quarters loaded with breach costs and recent recovered quarters, so they read differently depending on the reference window.

What ultimately needs verification is the durability of quarterly profits, actual growth in operating AI data center capacity, and the sequencing of capital between investment and dividends; this report is for information purposes and contains no buy or sell opinion or target price.
