Company Overview
Han Mi Semiconductor, founded in 1980 and listed on the KOSPI (South Korea's main stock exchange), is a specialist in back-end semiconductor packaging equipment. Its core product lines include vision placement systems, electromagnetic-interference (EMI) shielding equipment for smartphones, and — most critically — thermal-compression (TC) bonders used in the assembly of advanced AI chip packages. The company has emerged as one of the principal beneficiaries of the global AI semiconductor boom, having secured a near-monopoly position as the sole supplier of TC bonders to SK Hynix for packaging high-bandwidth memory (HBM) chips.
For much of its history, Han Mi exemplified the so-called "Korea discount" — the persistent tendency for South Korean equities to trade well below their intrinsic value despite strong fundamentals. Its price-to-book ratio (PBR) languished below 1x for extended periods even as the business generated healthy profits. Since the South Korean government launched its corporate Value-Up Programme to address this discount, Han Mi has become one of the more aggressive adopters of shareholder-return policies among mid-sized domestic manufacturers. Under chief executive Kwak Dong-shin, the company has combined rising dividends with share buybacks and cancellations in ways that have drawn favourable attention from the market.
Business and Financial Performance
*Products and competitive advantages*
Han Mi's competitive edge rests on more than four decades of accumulated manufacturing know-how and a substantial patent portfolio in back-end semiconductor equipment. Its three main product categories are: vision placement systems, which precisely position chips onto substrates; EMI shielding equipment used in coating smartphone semiconductors; and TC bonders, the thermal-compression bonding machines essential for stacking HBM chips. It is the last of these that has driven exceptional growth. As SK Hynix has expanded its share of the global HBM market — supplying the memory stacks that power Nvidia's AI accelerators — demand for TC bonders has surged, and Han Mi has retained an effectively exclusive position as supplier.
*Financial results*
Year | Revenue (bn KRW) | Operating profit (bn KRW) | Net profit (bn KRW) | Operating margin (%)
2019 | 128.9 | 21.5 | 20.4 | 16.7
2020 | 187.2 | 50.3 | 43.2 | 26.9
2021 | 296.1 | 102.0 | 90.1 | 34.4
2022 | 247.8 | 74.7 | 65.7 | 30.1

2024E | ~900.0 | ~380.0 | — | ~42
*2024 figures are estimates based on reported quarterly results.*
The trajectory since 2021 is striking. Revenue surged 67% year-on-year in 2023 to a record high, and 2024 appears set to break that record again on the back of explosive HBM equipment demand. An operating margin above 40% is exceptional by global standards for capital-equipment makers, reflecting the pricing power that comes with near-monopoly status and high technological barriers to entry.
The Value-Up Journey
*2021 — Formalising buybacks*
Han Mi began meaningfully scaling up its share-buyback programme in 2021, coinciding with that year's sharp profit growth. The company publicly disclosed buyback plans and began retiring a portion of the repurchased shares — a step that reduces the total share count and increases the value of each remaining share. Markets welcomed this as a positive signal, though the absolute scale remained modest.
*December 2022 — Higher dividends and a return-ratio commitment*
At the close of the 2022 financial year, Han Mi raised its per-share dividend and, for the first time, management began signalling publicly that it would maintain shareholder returns above a defined floor as a proportion of annual net profit. This commitment would serve as the foundation for the more formal policies that followed.
*2023 — Record profits, expanded distributions*
On the back of record earnings, Han Mi set its dividend at KRW 200 per share. Although the payout was higher than in prior years, some analysts noted that, against an operating margin exceeding 40% and operating profit above KRW 166bn, the absolute dividend remained modest. Combined buybacks and dividends implied a total shareholder-return ratio of roughly 25% of net profit.
*February 2024 — Pre-emptive share cancellation*
As the government's Value-Up Programme moved from discussion to formal policy, Han Mi announced the cancellation of a tranche of its treasury shares. This went beyond the common Korean corporate practice of buying back shares and holding them indefinitely — effectively a form of value hoarding rather than value creation. Retiring the shares outright signalled a genuine commitment to improving per-share value, and analysts noted it was an unusually swift response for a mid-sized KOSPI manufacturer.
*May 2024 — Formal shareholder-return policy*
In a disclosure filed in May 2024, Han Mi formalised its Value-Up commitment: a dividend payout ratio of at least 30% of net profit, combined with ongoing buybacks and cancellations, targeting a total shareholder-return ratio of 30% or above. The company also indicated it was considering the introduction of quarterly dividends. The announcement, framed in response to the Korea Exchange's Value-Up disclosure guidelines, attracted attention from foreign institutional investors.
*Second half of 2024 — Momentum compounds*
Demand for TC bonders tied to HBM3E packaging for Nvidia's AI chips accelerated sharply in the second half of 2024, driving a surge in orders. Han Mi's share price rose several-fold from its level at the start of the year, and its PBR re-rated well above its long-run average. The confluence of earnings momentum and shareholder-return commitments cemented the company's standing as one of the flagship beneficiaries of South Korea's Value-Up initiative.

Challenges and Assessment
*Challenges ahead*
Several structural risks cloud an otherwise compelling narrative.
Customer concentration. The overwhelming share of TC bonder revenue derives from a single customer, SK Hynix. This creates a chain of dependency running from Han Mi through SK Hynix to Nvidia's AI accelerator demand. Diversification to Samsung Electronics, Micron, or other HBM producers has been consistently identified by analysts as an urgent priority, but progress has been limited.
Cyclicality of shareholder returns. The current intensity of buybacks and dividends is underwritten by a period of exceptional earnings. Should the semiconductor equipment cycle turn down — as it did sharply in 2022 — cash generation will fall and the ability to honour return commitments may be tested.
Governance transparency. The company remains under the control of its founding family, a common structure in South Korea's corporate landscape. Institutional investors continue to question whether the board's independent directors provide genuine oversight. If shareholder-return policy rests entirely on the personal commitment of the controlling family rather than on enforceable board-level governance, it remains vulnerable to reversal in a downturn.
Intensifying competition. Han Mi currently holds a near-monopoly in TC bonders, but rivals — including Japan's Shinkawa and Toray, and America's Kulicke & Soffa — are investing heavily in competing technologies. Should Han Mi's technological lead erode, the earnings base underpinning its Value-Up story would weaken accordingly.
*Overall assessment*
Han Mi's Value-Up record is viewed positively within South Korean capital markets, primarily because it has moved beyond rhetoric. Share cancellations, higher dividends, and a publicly stated return-ratio target represent substantive rather than cosmetic change. The company has succeeded in attracting greater foreign institutional interest and in re-rating its stock from deep-discount to a premium multiple.
That said, the journey is far from complete. A 30% payout-ratio target falls well short of the 40–60% norms common among global blue-chip companies, and lags far behind the 50–80% total return ratios achieved by the industry's leading equipment makers — ASML, Lam Research, and Applied Materials among them. Governance remains an area of legitimate concern, and the durability of return commitments through a full earnings cycle is yet to be tested.
Controversies and Limitations
*Governance under founder-family control*
Han Mi operates under the concentrated control of its founding family. The independence and effectiveness of its outside directors has been a recurring concern among institutional shareholders. So long as shareholder-return policy is driven by the chief executive's personal discretion rather than anchored in board-level governance structures, the risk of commitments being quietly abandoned during a difficult period cannot be dismissed.
*Structural earnings volatility*
The company's fortunes are, in effect, a leveraged bet on SK Hynix's HBM investment cycle, which is itself a derivative of Nvidia's AI chip demand. The sharp profit decline Han Mi experienced during the 2022 semiconductor downturn illustrates how quickly conditions can deteriorate. Value-Up commitments made at the top of a cycle carry inherent credibility risk if they are not structured to survive a trough.
*Return ratios versus global peers*
Whilst Han Mi's 30%-plus payout target is above the South Korean corporate average, it remains unimpressive by global standards. Some institutional investors have noted a gap between the company's Value-Up declarations and the practical reality of its distributions relative to peers.
*Quarterly dividends: announced but not delivered*
Despite signalling in May 2024 that it was considering quarterly dividends, the company had not implemented them by year-end. Retail shareholders expressed frustration with what some viewed as an unfulfilled commitment. More broadly, investor relations activity — roadshows, earnings calls, and direct shareholder engagement — remains less developed than at larger KOSPI companies, an area that will need to improve if Han Mi is to maintain the trust of international investors over the long term.
