You've probably heard the term Korea Discount about a million times if you've spent any time looking at Asian markets. It's that nagging gap where Korean giants—Samsung, Hyundai, the names everyone knows—trade at prices that would make a Silicon Valley CFO weep. For decades, the narrative was simple: "It's the chaebols." People blamed the big family-run conglomerates for treating minority shareholders like an afterthought. But honestly? Things are shifting so fast right now that the old playbook is basically useless.
2026 is officially the year the "Value-up" talk turns into "Value-up" law.
We aren't just talking about voluntary suggestions anymore. As of January 2026, the South Korean government has pivoted from asking nicely to setting hard deadlines. If you're holding KOSPI stocks or even just watching from the sidelines, the landscape has fundamentally changed. The days of opaque boardrooms and "circular ownership" are being squeezed by a pincer movement of new legislation and a massive surge in shareholder activism.
The 2026 Mandatory Disclosure Hammer
The biggest piece of south korea corporate governance news hitting the wires right now is the expansion of mandatory reporting. Starting this year, every single company listed on the KOSPI—all 800+ of them—must submit a formal corporate governance report.
Previously, this was only a headache for the big fish with over 500 billion won in assets. Now? Even the mid-caps are in the crosshairs. It’s a "comply or explain" system. You either follow the best-practice guidelines or you explain to the entire market exactly why you aren't.
English Disclosures: No More Translation Lag
Foreign investors have complained for years about being the last to know. You'd see a massive price swing and realize a crucial filing was dropped in Korean three hours ago, but the English summary wouldn't show up for days.

That’s ending.
Phase II of the mandatory English disclosure roadmap kicked in on May 1, 2026. If a company has assets over 2 trillion won, they now have to provide English translations for all 55 categories of material disclosures. For the massive firms over 10 trillion won, that translation has to happen on the same day as the Korean filing. No more lag. No more "informational disadvantage."
Why the Commercial Act Changes Actually Matter
In July 2025, a landmark amendment to the Commercial Act basically rewrote the job description for board directors. This is the stuff that actually moves the needle on valuations. For the first time in Korean history, directors have a fiduciary duty not just to "the company" (which was often interpreted as "the founding family"), but to the shareholders as a whole.
It sounds like legal jargon, but it’s a massive shield for minority investors.
- Cumulative Voting: This is a big one. Large companies with assets over 2 trillion won can no longer "opt out" of cumulative voting. This allows minority shareholders to stack their votes for a single board candidate, making it way easier to get an independent voice into the room.
- Audit Committee Independence: Companies now have to elect at least two audit committee members separately from the rest of the board. Plus, there’s a 3% voting cap on the largest shareholder for these roles. Basically, it prevents the chairman from hand-picking the people supposed to be watching his back.
- Board Diversity: The requirement for "Independent Directors" (formerly called Outside Directors) has been bumped up to one-third of the board for all public companies.
Honestly, it’s about time.

The Activism Explosion of 2025-2026
If 2025 was the "Year of the Activist," 2026 is the year they start winning the war. Last year saw a record 255 activist campaigns in Korea. We saw names like City of London Investment Management and local players like Align Partners getting way more aggressive.
They aren't just asking for higher dividends anymore. They are gunning for board seats.
And they are winning. In the 2025 AGM season, activists secured 120 board seats across various firms. The "Korea Discount" is narrowing because the market finally believes that if a company sits on a mountain of cash without a plan, someone is going to show up and demand a share buyback.
The KOSPI Performance Shock
Check the numbers. The KOSPI leapt over 70% in 2025, ending the year at 4,214. Entering early 2026, analysts at firms like EpicAI are even whispering about the 5,000 mark. That's a "golden swan" recovery for an index that was basically the "ugly duckling" of Asia for two decades.
A lot of this is driven by the AI rally, sure, but the underlying "Value-up" program is the floor. When the government vowed to fix the discount, the market actually listened.

Real Talk: The Risks Still Exist
It's not all sunshine and rising tickers. There is still significant pushback from the chaebol families. Inheritance tax in Korea is still punishingly high—around 50%—which incentivizes families to keep stock prices low when they are preparing to pass the torch to the next generation.
Until the tax code catches up with the governance reforms, there will always be a natural friction between the government's "Value-up" goals and the families' desire to minimize tax bills.
Also, the 2026 AGM season in March is going to be the first real test of the new "detailed voting disclosure" rules. Companies now have to report the exact percentage of "for," "against," and "abstain" votes on the same day as the meeting. Expect some fireworks as the gap between what management wants and what shareholders want becomes public in real-time.
Actionable Insights for Investors
If you're looking at south korea corporate governance news to inform your portfolio, keep these points in mind:
- Monitor the 2 Trillion Won Threshold: Companies crossing this asset mark in 2026 face much stricter English disclosure and cumulative voting rules. These are prime targets for re-valuation.
- Watch the Share Buybacks: Total share cancellations in early 2025 already broke records. Companies that are aggressively retiring shares are the ones truly leaning into the "Value-up" spirit.
- Check the AGM Agendas: With the new fiduciary duty laws, look for companies facing shareholder proposals. Directors are now legally vulnerable if they approve deals that clearly hurt minority interests (like those messy "mergers" between affiliates).
- Use the New Tools: The English version of DART (the filing system) is finally becoming a reality. Use it to track executive compensation and stock-linked remuneration, which are now disclosed in much clearer detail.
The shift in Korean governance is no longer just a "vibe" or a political talking point. It’s codified. The 2026 reforms have created a transparency level that simply didn't exist three years ago. While the road is long, the "Korea Discount" is finally being treated as a problem to be solved, rather than an inevitable fact of life.
Next Steps for You:
Check the 2026 "Value-up Index" listings on the KRX website. The index is being re-evaluated this June, and companies that failed to implement their disclosed value-up plans are facing stricter criteria or removal. This is the fastest way to separate the companies that are just talking from the ones that are actually delivering for their shareholders.
