Is Hoban Group Trying to Take Over Korean Air?

Hoban Group, a mid-tier Korean homebuilder with no history in aviation, has spent four years quietly assembling a 20.15% stake in Hanjin Kal — the holding company that controls Korean Air — narrowing the gap with chairman Cho Won-tae's camp to roughly 0.4 percentage points. Hoban says the stake is a simple investment. But the timing lines up with a much bigger event: state-owned Korea Development Bank, which holds enough Hanjin Kal shares to currently keep Cho's camp ahead, has said it plans to sell that stake once the Korean Air–Asiana merger closes on December 17, 2026.

How Did a Homebuilder End Up Holding 20% of Korean Air's Parent Company?

Hoban's position in Hanjin Kal didn't start as a challenge to Korean Air's management. It began in 2022, when Hoban paid roughly ₩564 billion for activist fund KCGI's 13.97% stake, becoming Hanjin Kal's second-largest shareholder. Hoban kept buying steadily over the next four years, reaching a 20.15% stake by July 2026 — the point at which local outlets began describing the gap with the Cho family's own holdings as a genuine "governance variable" rather than a passive position. Hoban has consistently characterized the purchases as simple investment, but the scale and persistence of the buying have made that framing harder to take at face value.

The Cho family camp isn't undefended. Chairman Cho Won-tae's own stake is modest, but combined with allied holders — Delta Air Lines (14.9%), Korea Development Bank (10.58%), and logistics affiliate LX Pantos (3.83%) — the friendly bloc totals close to 49.9%. That figure looks comfortable until you notice that roughly a fifth of it belongs to a state bank that has already announced it intends to sell.

Where Did Hoban Get the Money to Build This Stake?

Hoban's war chest traces back to a controversial practice in Korean real estate development known as "bee-swarm bidding" (벌떼입찰). When Korea's state land developer, LH, releases a portion of a new town's public land to private builders, allocation runs by lottery — any company with three years and 300+ housing units of track record can enter. Mid-tier builders exploited this by registering dozens of nearly dormant shell subsidiaries to enter the same lottery under different names, mathematically stacking the odds in their favor.

Builder	Shell Subsidiaries Used for Bidding
Jungheung Construction	47
Daebang Construction	43
Woomi Construction	41
Hoban Construction	36
Jeil Construction	19

Large conglomerate-affiliated builders are barred from this by fair-trade rules limiting intra-group transactions, which is a large part of why big-name apartment brands are conspicuously absent from many new towns built over the past decade. Mid-tier builders faced no such restriction, won a large share of LH's private-lottery land at below-market cost, and built high-margin apartment complexes on it. Jungheung famously recycled its proceeds into acquiring Daewoo E&C; Hoban has been doing something similar, just aimed at a very different kind of asset. Regulatory scrutiny of the practice intensified starting in 2025, and new-project pipelines for these builders have thinned since — meaning the war chest Hoban is now deploying was largely built before the door started closing.

What Was the LS Corp Fight About, and Why Did Hoban Walk Away From It?

Before Hanjin Kal, Hoban's stake-building target was LS Corp, the holding company behind LS Cable & System — and the reason traces back to a subsidiary. Hoban acquired a 41.95% stake in Daehan Cable in 2021. LS Cable sued Daehan Cable in 2019 for patent infringement over high-voltage power distribution components and won in both the first and second trials; Daehan Cable didn't appeal further, and the ruling — roughly ₩1.5 billion in damages — became final. A far larger dispute followed: Korean police spent three years investigating whether Daehan Cable had obtained LS Cable's submarine high-voltage cable (HVDC) factory design know-how through an architecture firm that had worked on both companies' plants, and referred the case to prosecutors in May–June 2026 with 13 people, including Daehan Cable executives and architecture-firm staff, facing trade-secret violation charges. LS has said it will pursue trillion-won-scale civil damages if the criminal case results in a conviction; Daehan Cable denies requesting or using any LS design materials.

While that dispute unfolded, Hoban built a roughly 3-4% stake in LS Corp itself — enough to secure access to internal accounting records, which several analysts read as leverage for the litigation rather than a takeover attempt. LS responded with a standard defensive playbook: canceling 3.1% of outstanding shares in August 2025 to lift the price and raise the cost of further accumulation, and issuing ₩65 billion in exchangeable bonds to Hanjin Group — bonds that convert into treasury shares and, unlike treasury stock itself, carry voting rights once converted. That made Hanjin a "white knight" for the LS family. In November 2025, Hoban sold its entire LS Corp stake, reportedly booking upward of ₩100 billion in profit, and exited the fight entirely.

⚠️ The LS Exit Isn't Necessarily a Retreat

Reading Hoban's LS Corp exit as a sign it has lost its appetite for shareholder pressure campaigns would be a mistake: the proceeds appear to have been redirected almost directly into further Hanjin Kal purchases. The pattern across both situations is the same — build a large minority stake, gain informational or negotiating leverage, and either extract value or wait for an external event (here, KDB's planned divestment) to change the balance of power. Whether that produces an actual attempt at control, a negotiated settlement, or another profitable exit is not yet resolved, and Hoban's own public position remains that the Hanjin Kal stake is a financial investment.

What Happens to Hanjin Kal's Ownership After the Merger Closes?

The Korean Air–Asiana merger is set to close on December 17, 2026, forming a single "integrated Korean Air." Korea Development Bank has stated it intends to review divesting its Hanjin Kal stake once the integration is complete, framing the holding as a legacy of Asiana's earlier bailout rather than a strategic position it wants to keep. If KDB sells to the open market, to Hoban directly, or to another party unaligned with the Cho family, the friendly bloc supporting current management could shrink well below its current ~49.9% headline figure. If KDB instead sells to a buyer aligned with Cho Won-tae, or the sale is delayed, the current balance could hold. Hanjin Kal's free float also matters here: individual retail investors held 33.8% of the company as of September 3, 2026 — a large enough bloc that how it votes, rather than any single institutional holder, could ultimately decide a close contest.

✅ What to Watch Before December 17, 2026

• How and to whom KDB structures its Hanjin Kal exit — a block sale to a single buyer changes the math very differently than a gradual market sale.
• The prosecution outcome of the LS Corp trade-secret case — a conviction could expose Daehan Cable, and by extension Hoban, to civil liability large enough to affect its capacity to keep funding the Hanjin Kal position.
• Any further Hoban share purchases or public statements before the merger closes, which would be the clearest signal yet of intent beyond "simple investment."

Hoban's war chest — built on discounted land won through a lottery loophole, then expanded further by profitably exiting a fight with LS Corp — is now aimed at the one Korean shareholder registry where a single state bank's decision this December could decide who actually controls Korean Air.

What Should Investors Watch Next?

Two related threads are worth following alongside this one: the broader pattern of family succession and thin controlling stakes at Korean conglomerates like LS Group, where third-generation ownership is fragmented across dozens of heirs, and a closer look at Korea's "bee-swarm bidding" controversy and the regulatory crackdown now reshaping how mid-tier builders fund their next move.

Frequently Asked Questions

Q1. Is Hoban Group actually trying to take over Korean Air?

A. That isn't confirmed. Hoban has consistently described its Hanjin Kal stake as a financial investment, not a takeover bid. What is confirmed is that its 20.15% stake narrows the gap with the Cho family's aligned bloc to roughly 0.4 percentage points, and that the timing coincides with Korea Development Bank's planned post-merger divestment of its own Hanjin Kal shares — which is why analysts are watching the situation closely rather than dismissing it.

Q2. What is "bee-swarm bidding" and why is it controversial?

A. It refers to mid-tier Korean builders registering dozens of largely inactive shell subsidiaries to enter the same public-land lottery run by state developer LH, multiplying their odds of winning discounted land that large conglomerate-affiliated builders are barred from bidding on due to fair-trade restrictions. Regulators began cracking down on the practice starting in 2025.

Q3. Why does Korea Development Bank's Hanjin Kal stake matter so much?

A. KDB's roughly 10.58% stake is currently counted as part of the bloc supporting Chairman Cho Won-tae's management, but KDB has said it plans to review selling that stake once the Korean Air–Asiana merger completes on December 17, 2026. Depending on who buys it, that single sale could either preserve or erase the current management's narrow advantage over Hoban.

A construction company now holds nearly a fifth of Korean Air's parent — and the deciding vote may belong to a state bank that has already said it plans to sell.
