Samsung C&T Corporation
South Korean conglomerate arm that builds megaprojects and trades for the Samsung group.
On the record
Checkpoint: Q3 2026 earnings and further National Pension Service civil suit hearings
The call
Samsung C&T leans on Samsung group capex and sovereign megaprojects while its home construction business loses ground to domestic rivals.
Samsung C&T builds massive construction projects (like the Burj Khalifa and nuclear plants) and manages trading and energy businesses while holding key stakes in Samsung Electronics and Samsung Life Insurance. It is hard to replace because it has a 12-year track record as Korea's top builder, gets exclusive access to Samsung Electronics' huge factory construction projects that competitors cannot bid on, and has a proven history winning repeat work from Gulf and Korean governments. The main things to watch are whether a court ruling in a shareholder lawsuit over a 2015 merger will damage its reputation, and whether new data center projects it is bidding on actually turn into real contracts in the coming quarters.
Why
01
AI pressure: None apparent. AI data-center and chip-fab construction is work Samsung C&T builds for Samsung Electronics, not a force displacing it. Could AI do the core job? Unlikely.
02
Bigger players: Hyundai E&C and GS E&C. Samsung C&T fell to 3rd in new domestic construction orders in H1 2026, behind Hyundai E&C and GS E&C. Could a giant copy it? No, they are blocked.
03
What protects it. Captive construction pipeline from Samsung Electronics' fab and data-center capex, plus cross-shareholdings that make it the group's de-facto holding company.
What would change this call
H2 2026 Korean builder order-ranking tables (KRW value) versus Hyundai E&C and GS E&C. Shows whether Samsung C&T is losing or regaining domestic order share to rivals.
Whether the Oct 2025 OpenAI floating-data-center LOI converts into a signed, firm contract by mid-2027. Confirms whether the AI-data-center pipeline becomes real revenue or stalls.
Outcome of the National Pension Service civil suit over the 2015 merger (hearings from March 2026). Would show whether governance/legal risk turns into a material financial or reputational hit.

Questions people ask
- Is Samsung C&T profitable in 2025?
- Yes. Samsung C&T reported FY2025 revenue of KRW 40.742T, down 3.2% from KRW 42.103T in 2024, with operating profit of KRW 3.293T, as disclosed in its 2025 annual and Q4 earnings release dated 2026-01-27.
- Could AI replace Samsung C&T?
- No. Its core is physical EPC execution and megaproject delivery (Burj Khalifa, Barakah nuclear), not AI-substitutable. Samsung C&T is instead building AI infrastructure itself, signing an OpenAI data-center LOI on 2025-10-01 and filing for a Chuncheon AI data center permit on 2026-07-07.
- Who owns Samsung C&T?
- As of December 2023, Lee Jae-yong (Samsung Group chairman) held 18.10% of shares, KCC Corp held 9.17%, the National Pension Service held 7.01%, and Lee Boo-jin and Lee Seo-hyun each held 6.23%, per disclosed shareholder data.

- Domestically, Hyundai Engineering & Construction and GS E&C outpaced Samsung C&T in new order volume in H1 2026, with Samsung C&T ranking 3rd at KRW 4.7163T in new construction orders versus their combined roughly KRW 15T, per Chosun reporting dated 2026-07-14.
- Is Samsung C&T facing legal risk from the 2015 merger?
- Yes, but partially resolved. South Korea's Supreme Court acquitted Jay Y. Lee of merger fraud charges on 2025-07-17, however a National Pension Service civil suit over merger losses began hearings on 2026-03-19, and a UK court partly overturned an Elliott Associates arbitration award in February 2026.
- Is Samsung C&T's construction business shrinking?
- Yes, in 2025. Engineering & Construction segment revenue fell from KRW 18.655T in 2024 to KRW 14.148T in 2025, with operating profit dropping to KRW 536B, though Trading & Investment revenue grew to KRW 14.636T over the same period, per company earnings dated 2026-01-27.
