In May 2015, Cheil Industries offered to buy Samsung C&T in an all-stock deal valued at about 8.9 trillion won, roughly $8.11 billion.1 At the time, Samsung C&T's 4.06% stake in Samsung Electronics alone was worth close to $8 billion.1 Put those two numbers side by side and the offer was pricing one of Korea's largest builders and trading houses at approximately nothing, on top of a stock position the market already agreed was worth the entire deal. Nobody at Samsung called this a giveaway. The ratio came out of a formula in Korean securities law, and the formula was followed exactly.2
That is the whole story in miniature. Everything that happened over the following eleven years, the injunctions, the pension fund vote, the special prosecutor, a president's impeachment, a cabinet minister's prison sentence, effective control of Samsung Electronics changing hands through a merger of two smaller affiliates, is what happens when a rule followed exactly still produces an answer nobody defending it actually believes.
The ratio was a formula, and the formula was the point
Korea requires listed-to-listed mergers to be priced off recent market trading averages rather than asset or earnings value.2 Samsung C&T had spent years trading at a discount to what it actually held, the ordinary fate of a conglomerate affiliate whose price reflects the market's opinion of the whole group's governance rather than its own balance sheet alone. Cheil Industries, freshly listed the previous December, carried a growth story built on its fashion, resort, and biopharmaceutical holdings. The formula took both prices exactly as May 2015 happened to be quoting them and called the result fair.
Elliott Management, which had built a stake in Samsung C&T, argued the ratio undervalued its shareholders by roughly a third and pushed for a recalculation.3 It was arguing with a calculator that had already done its job correctly. Everyone on Yeouido could tell you Samsung C&T traded cheap because of the group's cross-shareholding structure. That fact didn't disqualify the price from being used. It just meant the price already knew about the discount and quoted it anyway. Using it as the merger value didn't correct the discount. It notarized it.
Lee Jae-yong held 23.2% of Cheil Industries and negligible direct Samsung C&T stock.3 A ratio favorable to Cheil converted his Cheil position into effective control of Samsung Electronics without him buying a single incremental share of it at market price. Nothing about that required breaking a rule. It required knowing, in advance, which day's closing price you wanted the law to treat as the truth.
How a silent share learns to vote yes
Under Korean company law, a company's own treasury shares carry no vote. Samsung C&T held roughly 5.7% of itself in treasury, and days before the shareholder meeting, sold that block to KCC Corporation, a friendly building-materials firm that then voted it for the merger.5 A buyback is normally marketed as a signal that management believes in its own stock. This one was a signal that management believed in exactly one buyer it could trust with the difference between silence and a yes vote.
Elliott went to court twice, first to block the shareholder meeting itself, then to void the KCC sale and stop those shares from voting. The Seoul Central District Court denied the first request on June 30.6 The Seoul High Court rejected the appeals on both on July 16, one day before the vote.7 No statute was bent to get there. Converting mute stock into a loyal bloc, on the eve of the one meeting where it mattered, was simply available to a board willing to authorize the sale and a court willing to call that ordinary business judgment.
It took Korea until February 2026 to close that particular door, and even then it didn't say why. A revised Commercial Act now requires companies to cancel treasury shares within a year of buying them, on the grounds that disposing of them to a chosen buyer creates a control shift that looks like a rights offering but requires only a board vote to execute.26 The reform doesn't mention Samsung C&T or KCC by name. It didn't have to. It closes exactly the door they walked through, eleven years and one merger too late for anyone who was still a Samsung C&T shareholder in 2015.
The shareholder who answered to a cabinet minister
The National Pension Service held 11.21% of Samsung C&T, its largest single shareholder, and multiple outlets described its vote as the swing that carried the merger past the two-thirds threshold.89 NPS is the kind of institutional holder finance coverage treats as a stand-in for the market's own sober judgment: enormous, diversified, professionally staffed. It is also a fund whose governing structure runs through the Ministry of Health and Welfare, which means in a contested vote, that is exactly where pressure has somewhere to go.
The mechanics of how it went are on the record. NPS routed this specific decision through its own internal Investment Management Committee rather than the higher Fund Management Committee, chaired by the health minister, that it had used for a comparable SK Group merger vote earlier the same year. That committee approved the merger 8 to 12 on July 10, 2015. NPS's chief investment officer had met Lee Jae-yong three days earlier.10 An internal report later surfaced showing that at a previously discussed ratio of 1:0.46, the swap would have been roughly neutral for the fund; at the actual ratio of 1:0.35, staff calculated a loss of about 138.8 billion won, and the research division was instructed to preset a synergy estimate of 2.1 trillion won sized specifically to offset it.11
Somewhere inside NPS, an analyst was handed a number and told to go find a model that arrived at it. That isn't valuation work. It's a word problem run in reverse, and the fund's own later review said so once nobody in government still needed the vote.11 NPS itself reportedly considered apologizing for the vote once the scandal broke.12
The vote passed. The verdicts didn't agree with each other.
Samsung C&T shareholders approved the merger on July 17, 2015, with 69.53% in favor, clearing the two-thirds supermajority the deal needed.9 A special prosecutor later established that Samsung had funneled support, including horses and equestrian training in Germany worth roughly $7 million, to the daughter of Choi Soon-sil, a confidante of President Park Geun-hye, as part of a bribery scheme that included smoothing NPS's approval of the merger and backing Samsung's succession plan.13
What followed reads less like a single verdict than four separate courts each grading a different piece of the same afternoon.
Park was impeached, tried, and sentenced to 24 years in April 2018 on 16 of 18 counts, for bribery the trial court valued above 23 billion won across the full scheme.14 She was pardoned in December 2021.15 Moon Hyung-pyo, the health minister who oversaw NPS, was convicted of forcing the fund's endorsement of the merger without adequate diligence and causing it losses; the Supreme Court finalized his 2.5-year sentence on April 14, 2022.16 Lee Jae-yong was convicted in August 2017 of bribing Park to secure government backing for the merger, retried on remand, resentenced to 2.5 years in January 2021, and released on parole that August.1718 He was pardoned in August 2022.19
Then a separate case, the one that actually asked whether the ratio and the accounting behind it were fraudulent, ran its own course. Korea's securities regulator had already ruled in 2018 that Samsung Biologics, Cheil's most consequential holding, intentionally violated accounting rules in valuing its stake in a biosimilars joint venture, fined the company, and referred it to prosecutors.28 Prosecutors charged Lee and thirteen others with accounting fraud, stock manipulation, and breach of trust tied to inflating Cheil's value ahead of the merger. The Seoul Central District Court acquitted all of them on all 19 counts in February 2024.20 The appellate court upheld the acquittal on an expanded 23 counts in February 2025. The Supreme Court dismissed the prosecution's final appeal in July 2025, a ruling that cannot be appealed further.2122
Line those results up and the asymmetry is the finding. Everyone who touched the machinery that produced the vote was, at some point, held criminally liable, and every one of those liabilities was later commuted, paroled, or pardoned into non-consequence, except Moon's. His sentence is the only line item nobody managed to get waived. He is also the person in this story furthest from the money, a cabinet appointee doing what a cabinet appointee is told. On the actual question that started the fight in 2015, whether the ratio itself defrauded Samsung C&T's shareholders, the final and unappealable answer from Korea's courts is no.
Elliott got paid. Then it didn't.
Elliott's 7.12% stake wasn't enough to stop the merger, so it looked for a different forum.4 In 2018 it filed an investor-state dispute claim under the Korea-US Free Trade Agreement, arguing that the government had improperly directed NPS's vote against the fund's own economic interest, and sought roughly $770 million.23 In June 2023, a Permanent Court of Arbitration tribunal found Korea liable and awarded Elliott about $53.59 million plus 5% annual interest compounded from July 16, 2015, the day before the shareholder vote, a little over 7% of what it had asked for.23 With interest, that award had grown to roughly $108 million by early 2026.2425
On February 23, 2026, a UK court, exercising supervisory jurisdiction over the London-seated arbitration, annulled it. Its stated basis: the National Pension Service's vote could not be regarded as state action.24 The case was sent back to arbitration.24
Set that finding next to Moon Hyung-pyo's. A Korean court sent a sitting cabinet minister to prison, and made it final in 2022, for personally forcing a state pension fund to cast a vote it would not otherwise have cast. A UK court ruled in 2026 that the very same vote wasn't the state's doing at all. Both findings can't be true, and Korea gets the use of whichever one is standing in front of it: the minister's conviction when a domestic audience needs someone to have answered for it, the tribunal's characterization when a foreign claimant needs paying. Nobody in either courtroom has to reconcile the other one's record, because "state action" under an investment treaty and "abuse of authority" under a criminal code are different questions asked by different judges who never have to read each other's opinions.
The practical translation for anyone who thinks a treaty claim is their backstop: winning an award against a government is not the same as collecting from one. A state gets to relitigate the legal character of its own conduct for years, in a country that isn't its own, and the forum matters more than the facts you already proved once.
What to check before a government-linked institution sits on your shareholder register
None of this is legal advice about a specific vote. Korea's rules on merger valuation, treasury share disposal, and pension fund governance are being actively rewritten in 2026, and the mechanisms described here should be tested against current law with qualified Korean counsel before you rely on any of them still being open.226 With that said, the diligence questions transfer to any jurisdiction where a state-linked fund, sovereign wealth vehicle, or politically governed pension plan might sit on your cap table or vote in a contest that matters to you:
- Who appoints the committee that instructs this institution's vote, and how many steps removed is that person from an election? NPS's decisive vote ran through an internal committee one health minister away from the presidency.
- Does the process match how this institution normally decides, or has this particular vote been routed somewhere friendlier than usual? NPS used a different committee for this merger than it had used weeks earlier for a comparable one.
- Are there treasury shares on the target's balance sheet, and who is the plausible friendly buyer if a board needs a vote manufactured on short notice? Model the outcome with and without that block voting.
- If your ultimate backstop is an investment treaty, understand that "state action" is litigated as its own question, separate from and potentially contradictory to any domestic finding that the same conduct was official pressure.
- Price a merger ratio against more than whatever valuation method your jurisdiction happens to require. Ask what asset or earnings-based number the required formula is quietly leaving out, and who benefits from the gap.
FAQ
Was the 2015 merger ratio itself ever ruled illegal?
No, not by any court, at any stage. The formula was applied correctly under the securities law that existed in 2015, and the Supreme Court's July 2025 ruling is the final word that no fraud was proven in the accounting or valuation behind it.21 The 2026 Capital Markets Act amendment requiring asset and earnings value alongside trading price is forward-looking, and its sponsors cited the unrelated Doosan Bobcat-Doosan Robotics merger, not the Samsung deal, as the case that moved it.2 Korea changed the rule without ever ruling the 2015 result wrong under the old one.
Does Samsung C&T still trade at a discount to what it holds?
As of mid-2026, activist investors continue to flag Samsung C&T's Samsung Electronics stake as trading well below what the underlying holding is worth, with one fund estimating the company as 63% intrinsically undervalued.27 The gap that made the 2015 ratio cheap for Cheil hasn't closed. It just isn't being used to acquire anyone at the moment.
The bill nobody waived
If you're building toward an exit that will require a shareholder vote you don't fully control, the transferable fact here isn't that Elliott lost. It's that losing didn't cost anyone who mattered anything durable. The minister's sentence is the one line item that never got reduced, paroled, or annulled by a court in a different country, and he is the person in this story who stood closest to being just an employee. Find out now whose employee is going to cast the vote that decides your company's next contested meeting, and find out who that person answers to on the one day it counts. By the time a special prosecutor is asking the same question, the merger will already be years old, closed, and past anyone's ability to undo it.
