Five Korean groups are weighing a Westinghouse stake that Seoul Economic Daily prices at $2.8 billion
Samsung C&T, Hyundai E&C and Doosan Enerbility are weighing a 5% to 10% stake in Westinghouse, the Korea Herald and Seoul Economic Daily reported. Seoul Economic Daily put the cost near $2.8 billion, a price that depends on Westinghouse going public.
The Investor · Invest desk
Key figures: Westinghouse could be valued at as much as $30 billion if it goes public. A 10% stake bought at a 10% discount would cost about $2.7 billion, or roughly 3.7 trillion won. A 5% stake at that valuation and discount would cost about $1.35 billion.
| Figure | Value | Note | Claim |
|---|---|---|---|
| Westinghouse value if it goes public, as much as | $30 billion | 4 | |
| 10% stake after discount | 2.7 about $bn | 5 | |
| 5% stake after discount | 1.35 about $bn | 18 |
What happened
- The government first proposed that domestic nuclear EPC companies take part and is now coordinating each company's investment intentions and the size of its contribution.
- Under the Korea-US agreement Korea can buy at a 10% discount to the offering price, so a 10% stake would still cost about $2.7 billion, or roughly 3.7 trillion won.
- Samsung C&T and Hyundai E&C see a chance at construction work on the eight US reactors, while Doosan Enerbility is eyeing reactor and steam generator orders.
- An SK official said: "It is true that there is active interest at the group level, but this is still under internal review and nothing has been finalized."
Why it matters
- contradiction If SK leads, as the Korea Herald has it, the state utilities may keep little of the cost; if KEPCO and KHNP lead, as Seoul Economic Daily has it, the five are junior co-investors.
- exposure A buyer paying 90% of the offer price is under water at cost once the shares trade below it, so the discount absorbs a 10% fall from the offer price and nothing beyond that.
- constraint Officials judged that KEPCO and KHNP could not carry a 10% stake alone, so their share now depends on how much the private five commit.
- decision SK has to decide whether to extend a $250 million small-reactor position into large reactors, the step Seoul Economic Daily says the new investment would allow.
Investment banking sources put Westinghouse's value at as much as $30 billion in a listing [4], and the Korea Herald gives the same figure for an IPO valuation [12]. Run that ceiling through the discount (which applies to an offer price that does not yet exist) and the range is narrower than the headline suggests. A 10% stake at $30 billion would cost $3.0 billion at the offer price [16], the discount takes $0.3 billion off that [17], and a 5% stake on the same terms would cost about $1.35 billion [18]. The paper's estimate of about 4 trillion won, or $2.8 billion [2], therefore sits at the top of that range and a little above it, because its own price for the full 10% is 3.7 trillion won [5]. The headline is 0.3 trillion won higher [19].
The two papers describe different structures. Seoul Economic Daily has private companies joining a government-led investment spearheaded by KEPCO and KHNP, with the aim of easing the burden on the state-run firms [21]. The Korea Herald, citing reports on Wednesday, says Samsung C&T, Hyundai E&C and Doosan Enerbility are among companies considering a consortium led by SK [22]. It describes the Korea-US agreement as already including a Korean private-sector consortium for the 5% to 10% [11].
In our view the cheque is an entry fee. The $2.8 billion is 2.3% of the $120 billion programme for eight US reactors [15], and Westinghouse works in large-reactor design, fuel and maintenance [14], so the contractors would be buying into a reactor designer. The reports do not say whether owning its shares improves a bidder's odds on any of the eight reactors.
SK is the counter-case. It put $250 million into TerraPower in 2022 [8] and cites AI data-center and semiconductor power demand [10], so for SK the shares themselves may be the objective.
We would drop the view if the eight reactors are awarded with no regard to who holds Westinghouse shares, since $2.8 billion would then buy a minority position and nothing else.
What to watch
- A Westinghouse listing filing with a price range: a valuation below $30 billion cuts the stake cost under the $1.35 billion to $2.7 billion band computed here.
- SK moving from an internal review to a stated amount, or any of the five naming a figure for its contribution.
- A published split of contributions between KEPCO and KHNP and the private group, which would show whether Seoul Economic Daily's or the Korea Herald's structure is right.

Investment banking sources say Westinghouse could be valued at as much as $30 billion if it goes public.

SK Inc. and SK Innovation invested $250 million in 2022 in TerraPower, the U.S. small modular reactor company founded by Bill Gates, and if the new investment goes ahead SK could expand its nuclear business beyond SMRs into large-scale reactors.
- [9]
"It is true that there is active interest at the group level, but this is still under internal review and nothing has been finalized," an SK official said.
- [10]
SK Group has signaled strong interest in joining the investment, citing rising power demand driven by AI data centers and the semiconductor industry, and wants to secure energy infrastructure including nuclear power as a future growth engine.
- [11]
The Seoul-Washington agreement includes a plan for a Korean private-sector consortium to acquire a 5-10 percent stake in Westinghouse.
- [12]

- [14]
Westinghouse has a broad presence across the conventional nuclear power industry, including large-scale reactor design, nuclear fuel and maintenance.
- [15]
The $2.8 billion estimate is about 2.3% of the $120 billion reactor programme.
- [16]
A 10% stake at a $30 billion valuation costs $3.0 billion at the offer price.
- [17]
The 10% discount takes $0.3 billion off a $3.0 billion stake, leaving the $2.7 billion Seoul Economic Daily quotes.

- [21]
The plan would have private companies join a government-led investment spearheaded by KEPCO and KHNP, easing the financial burden on the state-run firms while giving the private sector a foothold in the U.S. nuclear market.
- [22]
Samsung C&T, Hyundai Engineering & Construction and Doosan Enerbility are among the Korean companies reportedly considering joining a consortium being led by SK.
