LG Uplus

LG Uplus is Korea's third-largest telecom operator, built on three pillars: wireless (mobile), smart home (IPTV and broadband), and enterprise infrastructure (AI data centers, enterprise lines, solutions).

In the Q2 2026 segment figures the company disclosed, mobile revenue rose 0.9% year on year to KRW 1,660.2bn, smart home rose 4.3% to KRW 663.8bn, and enterprise infrastructure rose 8.6% to KRW 464.4bn, of which AIDC was KRW 124.1bn, solutions KRW 134.6bn and enterprise lines KRW 205.7bn.

On the subscriber base, total mobile lines reached about 31.47mn (MNO 22.44mn, MVNO 9.03mn) and 5G handset users numbered 9.548mn, taking the 5G share of handsets to 84.9%.

In fixed line, broadband subscribers stood at 5.677mn and IPTV subscribers at 5.776mn, supporting steady household revenue anchored by bundled products.

On tariffs, the company launched 'Simply 2.0' in May 2026, consolidating 53 existing 5G and LTE plans into 18 and adding an 'All-in-One' product that signs up mobile and broadband in one step.

In AI, the call application ixi-O and enterprise AICC are the core assets, and the company said its agentic AICC lifted answer accuracy to 89% using large language models and applied sub-second latency technology developed with OpenAI.

On competitive structure, SK Telecom set up a dedicated AIDC entity, SK Hyper, with KRW 750bn of committed capital through 2030, whereas LG Uplus runs the business directly inside the company under a 'One LG Solution' approach and KT operates it out of headquarters.

Analysts cite capital efficiency from tapping group affiliates' cooling, power and network capabilities as a strength, while noting that the investment burden lands directly on the parent balance sheet and channels such as project financing are comparatively limited.

Overseas, the company agreed with Malaysian operator Maxis to pursue a local commercial launch of ixi-O, structured as a software-as-a-service export model.

Annually, revenue climbed steadily from KRW 13,906.0bn in 2022 to KRW 14,372.6bn in 2023, KRW 14,625.2bn in 2024 and KRW 15,451.7bn in 2025, yet operating income slid from KRW 1,081.3bn in 2022 to KRW 998.0bn in 2023 and KRW 863.1bn in 2024 before turning back up to KRW 892.1bn in 2025.

Operating margin also compressed from 7.8% in 2022 to 5.9% in 2024 and 5.8% in 2025, marking a stretch where top-line growth did not translate into profit.

Net profit attributable to owners dropped from KRW 622.8bn in 2023 to KRW 374.5bn in 2024 before recovering to KRW 523.9bn in 2025, and 2025 operating cash flow of KRW 2,963.8bn kept cash generation thick relative to reported earnings.

On the balance sheet, the debt-to-equity ratio declined for four straight years, from 134.0% in 2022 to 129.5% in 2023, 124.8% in 2024 and 117.1% in 2025.

The quarterly path was volatile: operating income fell from KRW 304.5bn in Q2 2025 to KRW 161.7bn in Q3 2025 and KRW 170.5bn in Q4 2025, then rose to KRW 272.3bn in Q1 2026 and KRW 344.5bn in Q2 2026.

That swing is explained by the fact that the company ran a voluntary retirement program for employees aged 50 and above in Q3 2025, with the resulting workforce restructuring showing up as fixed labor cost savings from 2026.

Revenue eased from KRW 3,803.7bn in Q1 2026 to KRW 3,694.9bn in Q2 2026, largely on shrinking handset sales, while the company reported Q2 2026 service revenue up 2.0% at KRW 3,076.5bn, an 11.2% margin on service revenue, and EBITDA up 5.9% at KRW 1,034.8bn.

On costs, labor expenses fell 2.5% year on year and marketing spend declined 6.9% from the prior quarter, and the company said that excluding one-off items the operating profit growth rate was around 5%.

In short, the Q2 2026 improvement combined enterprise infrastructure growth with cost efficiency, and the one-off adjustment leaves room for differing reads on the true scale of the improvement.

Korea's mobile market is mature, with limited headroom from line growth and tariff competition alone, and the three carriers are shifting the competitive axis toward AIDC as a new revenue source amid stalled core-business growth.

Policy is reinforcing that shift: the government launched an 'AI Data Center Alliance' involving the industry ministry and the Ministry of Science and ICT, and said it will foster 18.4GW of AIDC capacity by 2035 as a national strategic industry.

Investment scale differs sharply by operator: SK Telecom plans to bring 5GW of AIDC online in phases from 2029 and expand to 15GW by 2035, KT has flagged KRW 6trn over five years including KRW 5trn for AIDC and KRW 1trn for submarine cables, and LG Uplus has committed roughly KRW 2trn including the Paju AIDC.

The gap also shows in reported results, as SK Telecom's Q2 2026 AIDC revenue rose 92.5% year on year to KRW 136.2bn.

A shared industry challenge is equally clear: the three carriers are ramping AI investment aggressively but have yet to establish clear service revenue models to recoup it, and observers argue they must generate recurring revenue from their own services rather than only competing on data centers and GPUs.

On tariff regulation, the Ministry of Science and ICT will implement an 'optimal tariff notification' scheme with the three carriers from October 2026, informing users when a more favorable plan exists, a variable for average revenue per user.

In response, the industry expects carriers to accelerate launches of premium plans bundling generative AI and OTT services ahead of the October rule. The asymmetric way regulatory risk can fall on individual operators is another defining feature of this sector.

Management's stated direction for 2026 pairs profitability management in the core telecom business with faster AI transformation.

First-half service revenue on a standalone basis rose 3.4% year on year, above the 2% annual growth target set at the start of the year, and CFO Yeo Myung-hee said wireless revenue growth would moderate in the second half but the annual guidance was comfortably achievable.

Capex is rising: the CFO said 2026 capex would increase year on year on expanded AI data center investment but would stay within EBITDA, that leasing and DBO models alongside owned centers would ease cash flow pressure, and that the program would be kept within mid-to-long-term targets without separate external funding.

Paju is the key milestone.

The company is building the 200MW Paju AIDC with roughly KRW 2trn of investment and plans to bring four buildings online sequentially from 2027 through 2028, and it said it pulled the construction schedule forward to meet rising demand, is securing additional power capacity via DBO, and is pursuing regional sites in parallel.

Longer term, the company has set a target of KRW 5trn in cumulative AIDC orders by 2030 with 15-20% average annual revenue growth.

In AI services, second-half priorities include upgrading ixi-O features, expanding voice AI through cooperation with Ericsson, and broadening an LLM-based callbot and chatbot lineup on finance-led AICC demand, while the Maxis agreement positions ixi-O for a localized commercial launch in Malaysia within the year on a SaaS basis.

On shareholder returns, the late-July board raised the interim dividend by 8% year on year and expanded the share buyback to KRW 90bn, with repurchased shares intended for cancellation.

The upshot is that until the first Paju building starts up in the first half of 2027, depreciation and power costs arrive ahead of revenue, making that lead-lag the main earnings item to watch.
