The "Korea Discount" used to be a punchline in Seoul's finance circles. For decades, investors basically accepted that South Korean stocks would trade at a fraction of their global peers because of opaque boards and the iron-fisted grip of family-run chaebols.
Honestly? That era is ending.
If you're looking at korea corporate governance news today, the big story isn't just one law—it's a massive, structural wave of reforms hitting the market this week. As of January 18, 2026, we are seeing the literal "Value-Up" of the KOSPI in real-time. Just a few days ago, data from the Korea Exchange (KRX) confirmed that share buybacks and retirements have more than doubled since this initiative kicked off. We are talking about 21.4 trillion won in shares retired just last year. That is not a small number.
The Massive 3% Rule Shift You Can't Ignore
One of the most technical—but arguably most important—bits of news involves the "3% rule." If you’ve been following the Korean Commercial Code (KCC) amendments, you know that July 2026 is the big deadline. But companies are already scrambling to adjust their boards now during the January planning phase.
Basically, the 3% rule used to have a massive loophole. It capped the voting power of the largest shareholder at 3% when electing audit committee members, but only for certain types of directors. Controlling families could often sidestep this.

Not anymore.
Starting later this year, that 3% cap applies to all audit committee member appointments. It is a speed bump for dominant shareholders that they can't simply drive around. Large companies with assets over 2 trillion won are already looking at their board compositions for the upcoming March AGM (Annual General Meeting) season to avoid a public relations disaster or a loss of control to activist funds.
Why Today’s Cybersecurity Breach is Actually a Governance Story
You might have seen the headlines about the Kyowon ransomware incident or the attacks on Coupang and Upbit. Usually, that’s tucked away in the "tech" section. But in Korea right now, cybersecurity is being reframed as a core governance test.
Mid-tier companies like Coway and Daekyo are suddenly being judged by investors not just on their P/E ratios, but on how their boards oversee digital risk. It’s a shift from "compliance" to "accountability." If a board isn't protecting the data of millions of subscribers, can they really claim to be following the new FSC (Financial Services Commission) guidelines on shareholder protection? Probably not.

Mandatory English Disclosures: No More "Lost in Translation"
Foreign investors have complained for years that they get news days after Korean retail investors. It created an uneven playing field that kept big global funds away.
That gap is closing.
According to the latest FSC roadmap, Phase II of the mandatory English disclosure requirement kicks in on May 1, 2026. This is huge. If you’re a KOSPI-listed company with assets over 10 trillion won, you’ll soon have to file your English disclosures on the same day as the Korean ones. No more three-day delays. No more "waiting for the translation."
- Who is affected? All KOSPI-listed firms with 2 trillion won or more in assets.
- What must be disclosed? All 55 material items, including governance changes and fair disclosure items.
- The Goal: To make the Korean market as transparent as London or New York.
The Rise of Cumulative Voting
Another pillar of korea corporate governance news today is the mandatory adoption of cumulative voting. For a long time, companies could just write a clause in their articles of incorporation to opt out of it.

The new law basically says: "Nice try, but no."
Large listed companies can no longer exclude cumulative voting. This allows minority shareholders to concentrate all their votes on a single director candidate. If there are five board seats open and you have 100 shares, you can dump all 500 votes on one person. It’s the ultimate weapon for activist investors like Palliser Capital or City of London Investment Management, who have been pushing for more board representation in Korean holding companies.
What’s Actually Happening with the "Value-Up" Index?
The Korea Value-Up Index is the government's flagship project to reward "good" companies. But here is the nuance: it isn't just about who has the most money.
The KRX recently clarified that starting from the June 2026 re-evaluation, the index will prioritize companies that have successfully implemented their value-up plans. It's not enough to just file a plan and say you'll do better. You have to actually show the receipts. This has led to a record surge in treasury stock cancellations. Companies are realizing that the "Value-Up" label is becoming a prerequisite for institutional capital.
How to Navigate the 2026 Proxy Season
If you’re an investor or a corporate observer, the next three months are critical. The March 2026 AGMs will be the first time companies are required to disclose voting results in full detail—including exactly how many people voted "against" or "abstained" on every single agenda item.
- Step 1: Check the P/B Ratios. Look for companies still trading below 1x book value. These are the primary targets for reform-driven rallies.
- Step 2: Monitor Treasury Stocks. Watch for announcements regarding the cancellation of treasury shares. This is the clearest signal that a company is serious about the Value-Up program.
- Step 3: Read the English DART. Even if it’s still in the transition phase, the quality of a company’s English disclosures is a great proxy for how much they care about global investors.
- Step 4: Watch for Commercial Code Updates. There is already talk of a "Third Amendment" to the KCC that could make treasury stock cancellation mandatory across the board.
The landscape of South Korean business is changing from a "trust us, we’re a family business" model to a "show us the value" model. It’s messy, it’s loud, and it’s about time.
