Korea's Dual-Listing Ban: 3% Rule Lifts Holdcos, Hits IPOs

On July 6, 2026, the Financial Services Commission (FSC) and Korea Exchange unveiled the detailed standards for a dual-listing regime of "banned in principle, allowed by exception." Before taking at face value what you heard on a TV news segment, this piece checks first whether the policy actually exists, and then traces from start to finish how it will reshape our market.

On one economic broadcast's "Market Deep Dive" segment, the reporter opened like this: "The government has released detailed rules banning dual listings. For a spun-off subsidiary that dual-lists, they've decided to apply a 3% rule." He added that Korea's dual-listing ratio, at around 11%, is higher than the US and Japan, that it has been cited as a cause of the Korea discount, and that large IPO candidates such as HD Hyundai Robotics and CJ Olive Young would be affected.

The broadcast's closing line stuck with me: "This is a policy to add fewer dual listings, not to reduce them. Whether this is enough to claw back the Kosdaq and Kospi discount, we'll have to watch the market's judgment a bit longer."

This piece unpacks that broadcast in three steps. First, it verifies whether what the news reported is actually true. Second, it takes apart how the system works, to see what the facts actually change. Third, it maps how those changes affect the stock market and individual names, and what forks lie ahead, through three scenarios. To say the conclusion up front: the news got the facts largely right, and its final comment, "a policy that adds fewer, not reduces," pierced the essence and the limits of this regulation precisely.

In one line

This is a vaccine against future bad dual listings, not a cure for the roughly 11% already piled up in the market. The 3% rule, which caps the controlling shareholder's votes at 3%, hands ordinary shareholders the key to whether a subsidiary lists. Holding companies and parents are the clearest winners; the IPO market and brokerage IB take the sharpest headwind.

Fact-check: was the news true?

To lead with the conclusion, the core facts the broadcast reported line up almost exactly with the actual policy. First a quick comparison table, then item by item in detail.

The policy is real

On July 6, 2026, the FSC and Korea Exchange pre-announced an "amendment to the exchange's listing and disclosure rules" and a "dual-listing guideline," and opened a comment period. It is the first official, concrete set of detailed measures aimed at the practice of dual listing (a parent and subsidiary listed at once), long cited as a structural cause of the Korea discount. The broadcast was accurate to say "the first detailed measures on the dual-listing problem have appeared." The schedule matches the news too: the amendment and guideline run through a comment period until July 14, then take effect after resolution by the Securities and Futures Commission and the FSC's regular meeting.

The core frame: banned in principle, allowed by exception

The broadcast summarized the policy as "in a word, dual listings banned in principle, and allowed by exception." That too is accurate. Precisely, it bans in principle any asymmetric dual listing that fails to consider the interests of the parent's ordinary shareholders, and allows it by exception only when certain procedures and shareholder-protection requirements are met. In the past a subsidiary only had to clear a standard listing review; now an additional dual-listing special review standard applies.

Who it covers: a 20% stake, and down to sub-subsidiaries

The broadcast said "it can include affiliates in which the parent holds a 20%-plus stake, and even sub-subsidiaries that such an affiliate in turn holds above 50%." The rule targets unlisted subsidiaries that a listed parent effectively controls, and since affiliate and sub-subsidiary structures are weighed together in judging control, the news description fits the facts. The crux is that it aims at the structure of "a listed parent newly listing an unlisted subsidiary."

The low-weight exemption: revenue, operating profit, and assets 'all' below 10%

The broadcast said "a low-weight subsidiary with revenue, operating profit, and assets below 10% is seen as having limited shareholder impact, so some procedures are relaxed." The actual rule is a bit stricter. A low-weight subsidiary qualifies for a waiver of shareholder consent only if revenue, operating profit, and asset shares are 'all' below 10% of the parent. And even if all three are under 10%, the waiver does not apply if the subsidiary is deemed material given its expected enterprise value. The news got the broad shape right, but the conditions "all three" and "the enterprise-value caveat" are worth flagging. These two conditions hide a trap important enough to treat separately later.

The 3% rule: a de facto veto for ordinary shareholders

The broadcast explained that "voting rights above 3% are limited to reduce the influence of the largest shareholder and related parties, and an ordinary resolution requires a majority of shareholders present and at least one quarter of total voting rights." This part is very accurate. The 3% rule borrows the Commercial Act's method for appointing audit committee members: with the votes of the largest shareholder and related parties capped at 3%, consent is recognized only when a majority of the shares present, and at least one quarter of total shares outstanding, vote in favor. In particular, for listing a subsidiary spun off via a physical split, this shareholder consent is mandatory. An ordinary subsidiary that obtains consent also earns credit for its investor-protection efforts.

The 3% rule's significance is anything but small. In Korea's chaebol structure, where controlling stakes are overwhelmingly large, tying the largest shareholder's votes to 3% effectively lets ordinary (minority) shareholders decide whether the subsidiary lists. When the broadcast summed it up as "many steps are taken, but the key point is that in the end the shareholders judge," it correctly captured the heart of the system.

The parent board's five duties and the special committee

The broadcast said the parent's board must fulfill five duties: assessing the impact of the dual listing on shareholders, preparing protection measures, confirming shareholder communication and consent, a final board vote for or against, and disclosing the whole process. These five duties match the actual rule. In order: writing a shareholder impact assessment; preparing protection measures such as treasury-share cancellation or in-kind dividends; communicating with or confirming consent from ordinary shareholders; a board vote for or against, with notice to the subsidiary; and disclosing results at each stage. And the broadcast's point that this entire process must pass prior review and resolution by an independent special committee centered on outside directors and external experts is also true.

The exchange's second-stage review

The broadcast said the structure is one where the parent runs the process first, then the exchange verifies. Indeed, the exchange reviews operational and managerial independence, such as whether the subsidiary's main business depends excessively on the parent and whether the parent effectively makes the key management decisions. On top of that, it separately reviews whether the parent's board faithfully carried out the five duties and passed a favorable vote, and whether efforts to protect ordinary shareholders were sufficient. This fits the broadcast's account.

No exception for advanced industries either

The broadcast said "advanced industries like chips and AI face the same shareholder-protection principle, though when the need for funding is large it may be considered as a reference factor in judging the need to list." This too is accurate. The FSC said it will not grant privileges just because an industry is advanced, but will treat funding need as a reference factor in judging the need to list.

Backdoor and overseas listings are in the net too

The broadcast said backdoor listings, via merger or by attaching an unlisted company to an already-listed affiliate, and even overseas exchange listings, are all subject to the rules. True. Backdoor listings that produce the effect of a listing are subject to review, and for overseas listings too, the board of the domestic listed parent still bears the five duties. It is a design meant to close the side doors of loophole tactics in advance.

Penalties: 1 billion won, and a trading halt

The broadcast said a violation can draw a fine of up to 1 billion won, a one-day trading suspension, and disclosure-violation penalties. True. A fine of up to 1 billion won and a one-day trading halt apply, and if violations accumulate it can lead all the way to a delisting review.

The individual-company calls are largely right too

The broadcast made nuanced calls on individual companies as well, and these too fit the logic of the rules.

• Hanwha Energy: An unlisted company at the apex of the Hanwha group's governance, it is far from the typical structure of a listed parent listing an unlisted subsidiary, so it is somewhat distant from direct application.
• Hyundai Motor's Boston Dynamics: As an overseas listing matter, it is not subject to the domestic exchange's listing review, but since it is a subsidiary controlled by a domestic listed company (Hyundai Motor), the parent board's duties may still apply.
• HD Hyundai Robotics: As a subsidiary established via a physical split, it is likely to face strict review.
• CJ Olive Young: An ordinary subsidiary, but given its controlling stake (around 66% per the news) and share of enterprise value, the low-weight (under 10%) exemption looks hard to apply.

That said, since regulators themselves said "specific company cases can only be judged once an actual listing application arrives," these company-by-company calls are clearly "estimates based on the text of the rules."

Fact-check verdict

The policy's skeleton, the 3% rule's requirements, the five duties, the exchange review, the penalty level, the timeline, and the individual-company calls the broadcast reported all matched the actual rules almost exactly. The one point to fine-tune is that the low-weight exemption requires 'all three items' under 10% and carries an enterprise-value caveat, and in fact those two conditions hide a trap important enough to treat separately later. In other words, this news stood on trustworthy facts. So why did this regulation appear now, and in this form? Let us start with the backdrop.

Why now: dissecting the Korea discount

The number that says something is abnormal

The starting point for understanding this regulation is a single comparison figure. As of the end of last year, the dual-listing ratio of the Korean market was 11.2%. The same metric was 0.05% in the US (Nasdaq), 4.0% in Japan, 2.4% in China, and 2.7% in Taiwan. That is more than 200 times the US level. A market where "double counting" is this widespread is rare in the world.

The parent left as an empty shell

Why does dual listing eat away at share prices? The mechanism is this. Spin off a prized business unit into a subsidiary, list that subsidiary separately, and the market prices the value of that business into the subsidiary's stock. But the parent still holds the subsidiary's shares, so the same business value gets counted twice, once at the parent and once at the subsidiary. Knowing about this overlap, the market applies a "holding company discount" to the parent. A perception forms that the parent, having handed its growth engine to the subsidiary, is left an empty shell, and the parent's stock ends up deeply undervalued against net asset value (NAV). As one outlet put it, the minority shareholder's anger at being "left holding an empty shell overnight" comes from here.

The more fundamental problem is the conflict of interest between the controlling shareholder and ordinary shareholders. The controlling shareholder lists the prized subsidiary to raise capital and tighten group control, but in the process the parent's ordinary shareholders' share is diluted. This regulation puts "shareholder protection" front and center and imposes five duties on the board precisely to target that conflict of interest.

An IPO market already frozen

The regulation did not spring up out of nowhere. The H1 2026 IPO market had already frozen on the pre-announcement alone. From January to May 15 this year, 20 companies newly listed in Korea, down 47.4% from 38 in the same period last year. Total offering proceeds also fell 52.9%, from 2.1417 trillion won last year to 1.0079 trillion won this year. As big-ticket candidates sat on their hands to "wait and see," the drought of large deals dragged on.

It is worth noting that the actual cases of dual listing were themselves not many: about 4 in 2024 and 10 last year. The debate over the regulation's effectiveness (covered later) sprouts here. Meanwhile, regulators pointed to Duksan Hi-Metal as a model case, one that did a thorough shareholder-impact assessment and prepared communication and protection measures during a subsidiary listing. In effect, they offered a template for the "right" dual listing the regulation aims for.

What actually changes: the rules of the game

This regulation changes three big things: the nature of the listing review, who owns the listing decision, and the time and cost of listing. Let us take them one at a time.

From review to governance

The most fundamental change is the nature of the regulation. The old listing review was a technical gate that asked "did it meet the financial requirements?" This regulation is a governance review that asks "is this listing fair to the parent's ordinary shareholders?" The power to decide whether to list moves from the company and controlling shareholder to the independent judgment of the board and the consent of ordinary shareholders. This is not just a single rule but, I think, an attempt to rewrite the decision-making grammar of Korea's capital market.

The veto in ordinary shareholders' hands

With the 3% rule, listing a spun-off subsidiary is now impossible without ordinary shareholders' consent. Tie the controlling shareholder's stake to 3%, and the remaining votes decide the outcome. For a company pursuing a listing, this means a surge in uncertainty. No matter that the board passes it, if minority shareholders vote against it at the general meeting it can founder. Naturally, an incentive arises for the company to win over ordinary shareholders before listing with "carrots" such as bigger dividends, treasury-share cancellation, and in-kind dividends. This is where the virtuous cycle of shareholder returns the regulation intends can start to work.

A longer timeline, higher costs

The multi-stage process, from special-committee prior review to board resolution to shareholder communication and consent to exchange verification, clearly lengthens the time and cost to list. With backdoor and overseas listings pulled into the net, the "side doors" have narrowed too. It is a structure in which a company cannot help being far more cautious before it plays the subsidiary-listing card. In fact, there are already observations that many large IPO candidates are shelving listings or weighing alternatives such as a holding-company merger.

The gaps in the rules: loopholes and escape routes

Up to here is the set of rules the regulation newly built. But even the most refined rules have gaps, and the market always finds them first. This chapter follows in turn the three kinds of gaps the regulation leaves: the trap inside the exemption clause, the front door of the regulatory structure itself, and the escape routes that change the listing method wholesale. These gaps are exactly what determines the regulation's effectiveness.

The low-weight exemption trap: a new hole from plugging a hole

The two conditions of the low-weight exemption flagged earlier in the fact-check, the quantitative threshold of "revenue, operating profit, and assets all below 10%" and the caveat that "the exemption is excluded if the expected enterprise value is large," are not to be waved past. The two were paired to check each other, and their combination holds a classic regulatory dilemma of "opening a new hole while trying to plug one."

Look at the quantitative threshold first. Revenue, operating profit, and assets are all backward-looking accounting figures, so a company can engineer them to a degree. It can keep revenue optically low through intra-group transactions and revenue-recognition timing, shift operating profit through cost allocation (a loss is automatically below 10%), and shrink assets with an asset-light structure that leases instead of owns or parks core IP in a separate entity. On top of this come two games peculiar to threshold rules. One is the cliff effect: 9.9% means the shareholder vote is waived, 10.1% means a 3% rule general meeting, so a paper-thin difference swings the outcome to extremes, and a company has an incentive to land the figure right at the 9% range. The other is salami slicing: split one large subsidiary into several each below 10%, and individually all become exemption-eligible. Whether the rule aggregates them is a key question for the final version.

To plug exactly this loophole, the "enterprise-value caveat" was tacked on behind. But this bandage is a bigger spark. "Expected enterprise value" is not a clean number like 10% but a discretionary, forward-looking judgment. A company cannot know in advance whether it qualifies for the exemption, so the premise of its listing prep wobbles (unpredictability), and the judge's wide discretion invites disputes over consistency and favoritism (discretion and litigation risk). Above all, a company lists precisely because it is valuable enough to list separately, so if that gets it labeled a "material subsidiary," nearly every listing candidate falls out of the exemption. The low-weight exemption clause then becomes, in effect, a dead letter.

The sharpest problem is that overlaying the two conditions pins down exactly who gets caught.

That exact "small results, big valuation" combination, AI, bio, and deep-tech with long R&D cycles and thin revenue and profit but high market value, is precisely what the enterprise-value caveat catches. The low-weight exemption looks on the surface like a device that "considers small companies," but the innovators who most need capital are left out of that consideration. This is the basis for the venture industry's pushback that "chaebol slicing and a venture's subsidiary listing are different things." Whether the "funding-need reference factor" opened up for advanced industries is actually honored in practice will determine the size of this regressiveness.

In the end this clause's fate hinges on how much the final version defines "expected enterprise value," and either way a symmetric risk remains. Apply it loosely and the accounting engineering and slicing loopholes survive, stirring an effectiveness debate; apply it strictly and the exemption becomes a dead letter while ventures and growth stocks freeze (Scenario C, discussed later). Where to put the weight, between the clarity of a quantitative standard and the flexibility of a qualitative one, is what decides this clause's success, and it will be settled not in the document but in the precedents the first reviews create.

The regulation's front door: from "post-separation" to "pre-separation"

If the earlier trap is a gap inside the exemption clause, the bigger gap is in the structure of the regulation itself. This regulation's hook boils down to a single sentence: "a listed parent newly listing a subsidiary it effectively controls." Regulators tightly sealed the back doors out of that hook. They review backdoor listings such as mergers and affiliate insertions, impose parent-board duties even on overseas listings, and pull sub-subsidiaries into the governance net. Yet read the hook's wording in reverse and one front door stands open: place the subsidiary outside "the listed parent's control" in the first place, and it never gets caught on the hook at all.

So the biggest behavioral change this regulation will bring is companies moving up the "timing" of separation. The formula so far was "post-separation": grow a prized business inside the parent, then split it off at the last minute and list it. With the regulation taking direct aim at that method, the rational company's response shifts toward "pre-separation," standing the business up separately from the start and growing it independently. There are two paths here.

The first is growing it outside the listed parent. Set it up so that the owner family or an unlisted holding company controls the new business, and it escapes the very definition of "a subsidiary controlled by a listed parent," slipping the whole regulatory net. It is exactly the same logic by which this regulation cannot directly reach an unlisted company at the apex of group governance (the Hanwha Energy type). The problem is that a balloon effect bursts here. If a prized new business grows not in the listed shareholders' hands but in the owner's personal company, then on the spot where the dual-listing problem was pressed down, another governance problem, tunneling and self-dealing, swells up. Block one channel and the water flows to another.

The second is setting it up as a subsidiary from the start while dodging only the "physical split" label. In this case it is still a listed subsidiary, so it is subject to the rules at listing, but it can avoid the "consent mandatory" track attached to spun-off subsidiaries and take the ordinary-subsidiary track, where consent earns protection credit. And in the early days it is low-weight (under 10%), so the exemption is even on the table (though once it grows, it hits the "enterprise-value caveat" seen earlier).

This behavioral change is both good and bad. On the bright side, a business stood up transparently as a separate entity from the start is one the parent's shareholders invest in knowing "this was never mine," so the LG Energy Solution-style surprise value transfer (the sense of betrayal), discussed later, disappears. The conflict of interest is settled in advance, moving closer to a US-style independent-capitalization structure. On the dark side, if the prized growth engine grows outside the listed parent, existing shareholders are cut out of that growth story entirely, and the self-dealing channel just mentioned opens.

In the end, this regulation firmly curbs the "physical-split slicing" method, but the motive to separately capitalize a prized business does not disappear. That motive finds expression through other routes, pre-separation, growing outside the listed company, going overseas, or staying private. So the accurate phrasing is not "such a thing will never happen again" but "the form of the thing changes." And whether that changed form is better or worse for shareholders depends, once again, on how tightly regulators apply the "enterprise-value caveat" and the backdoor review in practice.

An escape-route map: private as an exit, overseas as a half-open door

If "pre-separation" is an escape that moves up the timing of separation, there are two more escape routes that change the very method of listing. Their characters are opposite: one is a door that leaves the regulation entirely (staying private), the other a half-open door (overseas listing).

First, staying private. As long as the regulation's hook is "listing," never listing at all means never getting caught in the net. Liquidity can be partly secured on K-OTC (the over-the-counter market) or private platforms like Securities Plus Unlisted and Seoul Exchange Unlisted, and growth capital raised through private means (pre-IPO rounds, CVC, PEF). But this path is close to a "last resort" that gives up the core benefits of an IPO wholesale: large offering proceeds, an exit at a high valuation, and M&A currency. Yet paradoxically, if a subsidiary stays private and fully inside the parent, its value accrues 100% to the parent (the holdco), so the dual-listing discount never arises in the first place. From a holdco re-rating standpoint it is actually the most ideal picture, and the direction the regulation ultimately means to induce.

Second, overseas listing. This is a "half-open" door. The domestic exchange's substantive review (the second-stage check of operational and managerial independence and so on) cannot reach a foreign exchange, so that part slips through. But even for an overseas listing, the board of the domestic listed parent still bears the five duties: the shareholder impact assessment, the protection plan, confirming consent, and disclosure all follow, and the penalties (1 billion won and the trading halt) are enforced indirectly through the domestic parent rather than the overseas subsidiary. The reason regulators deliberately narrowed this gap is clear. A prized subsidiary of a domestic listed company slipping overseas, as with the 2024 Nasdaq listing of Webtoon Entertainment controlled by Naver, or Hyundai Motor's Boston Dynamics weighing an overseas listing, was exactly the anticipated escape route. The appeal of a tech firm winning a higher valuation and global capital in the US is large, but local regulation and upkeep costs, reduced access for domestic investors, and the premise that a foreign exchange must accept the business in the first place come as the price.

Lay all these routes on one page and the conclusion converges on one thing: there is no fully free escape route.

Staying private dodges the regulation but gives up the benefits of an IPO; going overseas gains valuation but cannot dodge the parent board's duties. So a company ends up choosing an optimum inside the triangle of "business character times funding need times valuation maximization." Heavy funding pressure and a global-tech business point overseas; a wish to keep control and command points to staying private; sufficient domestic valuation and persuadable shareholders point to the head-on route. The answer will differ by company. The watch points differ for investors too: if a prized subsidiary stays private it is favorable for the parent (holdco) value, and if it lists overseas the domestic parent's shareholders may still be sidelined, so confirming that direction name by name is the crux.

A company-by-company impact map

Plug the rules and their gaps into individual companies, and the regulation's real weight varies enormously by governance structure. Below are estimates based on the text of the rules; the final call will come from the regulator's review when an actual listing application arrives.

On top of this, the market sees IPO candidates in chaebol groups with high business linkage, such as SK Ecoplant, as within the direct or indirect zone of impact. In short, the more a subsidiary has a spin-off history, is entangled with the parent's business, and carries a large share of enterprise value, the more heavily it feels the regulation.

The impact on the stock market, and the read

Now the core question. How does this regulation affect our market and investors' judgment? Let us split it into five strands pointing in different directions.

1. Re-rating of holdcos and parents: the clearest beneficiary

The most direct beneficiaries are holding companies and parents. Holdcos that long carried deep discounts to NAV as they spun off and listed prized subsidiaries now see that "subsidiary outflow" risk cut off institutionally. The expectation that the growth engine will stay inside the company narrows the discount. This is the backdrop to "holdco re-rating" already emerging as a powerful 2026 investment theme.

But a condition attaches to the read. Going forward, the crux of holdco re-rating shifts from "when to list the subsidiary and book the gain" to the competitiveness and financial stability of the parent's own business. With the listing card blocked, the wheat and chaff will separate between holdcos with solid substance and those without. Coupled with Commercial Act reform and the Value-Up (corporate value enhancement) policy, the re-rating's momentum could grow further.

2. The IPO market and brokerage IB: a clear headwind

On the other side are the public-offering market and brokerages' IB (corporate finance) divisions. When big-ticket listings are delayed or withdrawn, opportunities shrink for IPO investors, and a shadow falls over the earnings of brokerages that leaned on underwriting fees. The data of H1 new listings and offering proceeds cut in half shows the size of this headwind. An investment strategy dependent on IPO subscriptions must brace for a drought of catalysts for a while.

3. Easing the fear of physical splits: a floor for individual valuations

In the Korean market "physical split" was a word of dread for minority shareholders, and the archetype of that fear is LG Energy Solution. When LG Chem physically split its prized battery business off in 2020 and listed it separately in 2022, LG Chem's stock, robbed of its growth engine to the subsidiary, was crushed. The learned fear, that the moment the prized business of the company you bought is spun into a subsidiary and listed separately your stock becomes a shell, hardened here. In fact this very "LG-ES-type" controversy is part of the backdrop to this regulation's birth.

This regulation places an institutional safety valve on that fear. To physically split and list a large business like batteries from now on, a company must obtain the parent's ordinary shareholders' consent under the 3% rule, and its business weight is too large for the low-weight exemption. If minority shareholders vote against, the listing itself is blocked. The risk of a "surprise split-and-list" is institutionally lowered, and this can work as a psychological effect propping up the floor of individual valuations.

Still, three caveats must be clear. First, it is not retroactive. It cannot undo the LG-ES listing that already happened, and the stock of existing dual listings stays put (which is why it "adds fewer, not reduces"). Second, it is not an outright ban. If a company wins over ordinary shareholders with sufficient compensation, such as in-kind dividends or treasury-share cancellation, and obtains consent, listing is still possible. It hands the decision to shareholders rather than banning it. Third, this safety valve has the "pre-separation" escape route seen earlier, so even if it blocks the LG-ES-style method of betrayal, the motive can leak out through other channels.

4. Funding for ventures and growth stocks: a new risk

Where there is light there is shadow. The venture industry pushes back that "a chaebol's slicing listing and a venture's subsidiary listing are different." For a venture, a subsidiary listing is part of a growth strategy to nurture a new business or secure new technology, and the fear is that regulating it uniformly could shrink venture M&A and funding channels. Firms with long R&D cycles and low near-term results, like AI, bio, and deep-tech, are especially vulnerable. Opening a "funding-need reference factor" for advanced industries is a buffer conscious of this worry, but how flexibly it is honored in actual reviews is unknown. A growth-stock investor must factor in the new variable of constrained funding routes.

5. The foreign view: an opening signal for closing the Korea discount

Seen from afar, this regulation is a signal to foreign investors that Korea has begun to directly address the structural cause of the Korea discount. Governance improvement and shareholder protection are core items global investors watch when they re-rate the Korean market. If, alongside Commercial Act reform and the Value-Up program, this regulation actually works, over the medium to long term it can be priming water that lowers the discount across the whole market. Of course, that is conditional on "if it actually works."

Three scenarios: how it plays out from here

The policy's direction is set, but the outcome is open. Depending on how the regulation settles into the market, three futures are possible.

Scenario A: re-rating takes hold (optimistic)

Premise: The 3% rule and the board's five duties work in substance, and companies turn toward shareholder returns (treasury-share cancellation, bigger dividends) instead of listings. Commercial Act reform and Value-Up create synergy.

Development: Holdco and parent discounts narrow meaningfully, and as the fear of physical splits lifts, individual valuations step up a level. Foreign money flows in responding to the governance-improvement story. The Korea discount narrows gently.

• Winners: Holdcos with solid own businesses, chaebols active in shareholder returns, Value-Up beneficiaries
• Losers: Growth strategies that leaned on listing gains, IPO-dependent investing
• Investment takeaway: Watch holdcos and parents with "undervalued vs NAV + own-business competitiveness + shareholder-return will" from a re-rating angle

Scenario B: it stops at "adding fewer" (base / neutral)

Premise: The regulation curbs new dual listings, but the existing 11% stock of dual listings stays put. Companies seek escape routes such as mergers and overseas-listing reviews. The broadcast's "a policy that adds fewer, not reduces" becomes reality.

Development: The big-IPO gap drags on but the shock to the broad market is limited. Holdco re-rating differentiates by name, and the effectiveness debate ("what is needed is litigation and the Commercial Act, not a guideline") continues. The Korea discount does not narrow dramatically but settles into gentle improvement.

• Winners: Quality holdcos that survive the wheat-and-chaff sorting
• Losers: Low-quality holdcos that expected a blanket re-rating, the IPO market
• Investment takeaway: Beware thematic "buy all holdcos." Verify each firm's asset quality and shareholder-return record individually. Selectively watch voluntary unwinding (merger, full subsidiary) among existing dual-listed names

Scenario C: a funding freeze and a return to loopholes (pessimistic)

Premise: Uniform regulation actually strangles funding for ventures and growth stocks, and companies route around the rules via mergers and overseas listings. The advanced-industry "funding reference factor" becomes a dead letter in practice.

Development: Growth firms' listings and funding shrink and the Kosdaq venture ecosystem freezes. Backdoor-listing loopholes that dodge the regulation multiply, growing the debate over its legitimacy. The IPO slump transmits into brokerage earnings.

• Winners: Large holdcos in the regulation-free zone (relatively)
• Losers: Growth stocks, ventures, Kosdaq, brokerage IB, IPO investing
• Investment takeaway: Recheck the risk of loss-making growth stocks heavily dependent on funding. Beware governance risk in names tagged with regulatory workarounds (merger, overseas listing). Track the direction of policy patches (widening the advanced-industry exception, easing for ventures) as policy events

Scenarios at a glance

Reality is more likely to show the three scenarios mixed by name and sector. In the holdco sector A can work, in the IPO market B to C, and in the venture sector C's risk, all at the same time.

Conclusion: what investors should watch

Back to the broadcast's final comment: "This is a policy to add fewer dual listings, not to reduce them." That one line precisely sums up the essence and the limits of this regulation. It is a vaccine against future bad dual listings, not a cure for the roughly 11% already piled up in the market. Expect the Korea discount to heal from this alone and you may be disappointed. The real change comes when Commercial Act reform, Value-Up, and companies' own will for shareholder returns lock together.

So what should investors watch?

The system has set its direction, and the market has now entered the long process of translating that direction into prices. The regulation's success or failure will be decided not in the document but in the precedents the first cases create. As the broadcast said, it is time to watch the market's judgment a bit longer.
