Company overview
Hyosung TNC is the textiles and chemicals arm of Hyosung Group, one of South Korea's mid-sized conglomerates. Spun off in 2018 when Hyosung restructured into a holding-company model, it makes high-performance fibres including spandex, nylon and polyester yarn. Its commanding position in the global spandex market — where it has held the number-one spot by production capacity for years — has earned it the nickname "the spandex giant." The shares trade on the main board of the Korea Exchange (KOSPI).
Despite that dominant franchise, Hyosung TNC has spent years mired in valuation controversy, battered by extreme earnings swings and a weak record on shareholder returns. A brutal downturn in spandex markets between 2022 and 2023, compounded by a flood of cheap Chinese supply, sent the share price down more than 80% from its all-time peak. That collapse brought shareholder-value concerns to a head — and, when the South Korean government launched its Korea Value-up Programme in 2024 to encourage listed companies to address persistent undervaluation, Hyosung TNC found itself squarely in the spotlight.
Business fundamentals and financial performance
*A world leader caught in a commodity cycle*
Spandex — a stretch fibre used in athleisure wear, underwear and medical textiles — is the engine of Hyosung TNC's business. The company operates production sites across the United States, China, Vietnam, Brazil and Turkey. Demand surged after the Covid-19 pandemic, driving a "supercycle" in 2021 and the first half of 2022 that delivered exceptional margins. Then the cycle turned sharply. Chinese producers had been expanding capacity aggressively, and from the second half of 2022 a wave of new Chinese output flooded the market, crushing the spread between spandex selling prices and raw-material costs. Earnings collapsed from hundreds of billions of won to near zero, and the company slipped into an operating loss in 2023.

*Note: Some figures are estimates based on publicly available information and may differ from final reported results.*
A new management team installed in 2025 identified margin recovery as the prerequisite for any meaningful re-rating — prioritising cost-structure improvement, a higher mix of value-added products, and production efficiency gains over simple dividend increases. By January 2026, there were signs that Chinese spandex producers were cutting output and restructuring, raising hopes that Hyosung TNC could benefit from a rebalancing of global supply.
Value-up milestones
*2024: Korea Value-up Programme focuses attention*
When South Korean financial regulators formally launched the Korea Value-up Programme in 2024 — modelled loosely on Japan's Tokyo Stock Exchange initiative to push companies trading below book value to improve returns on equity — Hyosung TNC became an obvious candidate. Its price-to-book ratio had fallen well below 1x, a threshold that in Korea is shorthand for chronic undervaluation. Whether a company is included in the Korea Value-up Index now directly influences buying decisions by domestic institutional investors, so the pressure on management to articulate a credible shareholder-return policy sharpened considerably.
*May 2025: New leadership signals a strategic reset*
In May 2025, a management reshuffle was accompanied by a public commitment to rebuild profitability as the foundation for sustainable shareholder returns. The market interpreted this as the starting gun for a genuine value-up effort, distinguishing it from the simpler approach of boosting dividends in a favourable year and cutting them when markets turn.
*January 2026: Chinese rivals stumble, opportunity beckons*
Reports in January 2026 suggested that several Chinese spandex manufacturers were suffering losses severe enough to prompt production cuts and corporate restructuring. Analysts began arguing that Hyosung TNC — with its global scale and established customer relationships — was well placed to capture market share and improve margins as Chinese supply contracted. A recovery in earnings, they noted, would also replenish the resources needed to fund enhanced shareholder returns.
*February 2026: Governance reform — dual chief executives appointed*
On 26th February 2026, Hyosung TNC restructured its leadership, appointing Lee Chang-hwang and Yoo Young-hwan as co-chief executives. The company described the move as placing "operational leaders at the front line to strengthen execution." Markets read it as a meaningful shift away from a structure centred on the controlling family — the Cho family, founders of Hyosung Group — toward a more professionalised management model.
*March 2026: Analyst upgrades and share-price momentum*
On 4th March 2026, BNK Securities raised its target price for Hyosung TNC, citing the rising value of subsidiaries and the potential for expanded shareholder returns. The report was notable for making shareholder returns an explicit investment thesis rather than a secondary consideration. The shares responded: they surged 6.61% intraday on 18th March and rose a further 7.52% on 1st April, reflecting a confluence of value-up optimism and expectations of earnings recovery.
*March 2026: National Pension Service votes against chairman's re-election*
On 12th March 2026, Korea's National Pension Service — the country's largest institutional investor — cast its vote against the re-election of Cho Hyun-joon, the controlling chairman, to the board at the company's annual general meeting. The pension fund stated that it was exercising its proxy votes "proactively," signalling a broader intent to hold large-company founders to account. The vote brought governance concerns back to centre stage and reinforced pressure on the company to strengthen board independence.
*June 2026: Korea Value-up Index inclusion mooted*
By June 2026, reports indicated that institutional and foreign investors were concentrating buying in stocks linked to the Korea Value-up Index, and that Hyosung TNC was attracting attention as a potential constituent.
Challenges and assessment
*What still needs to be done*
The two most pressing tasks facing Hyosung TNC are, first, achieving durable profitability rather than cyclical bounces, and second, publishing a concrete, quantified shareholder-return framework. A one-off dividend increase funded by a temporary uptick in spandex spreads will not satisfy long-term investors. What is needed is a formal policy setting out a target payout ratio, a share buy-back and cancellation plan, and return-on-equity targets — all communicated publicly and maintained through the cycle.
On governance, the National Pension Service's vote against the chairman is a clear signal that institutional investors remain uncomfortable with the degree of family control. Practical reforms — raising the proportion of independent directors, establishing a board-level shareholder-returns committee, and making the family's role in strategic decisions more transparent — are widely seen as necessary steps.
A third concern is the risk of Hyosung TNC being used as a financial backstop for weaker group affiliates. Reports in June 2026 put the scale of support extended to a struggling chemicals subsidiary at approximately ₩810bn. When losses from that relationship flow back to ordinary Hyosung TNC shareholders while control of the affiliate remains with the Cho family, the result is a classic governance hazard: privatised control, socialised losses.
*Overall assessment*
Hyosung TNC has a genuine and formidable competitive asset in its global spandex leadership. The series of positive signals over 2025 and 2026 — new management, a co-CEO structure, analyst upgrades, and tentative signs of Chinese supply discipline — are encouraging. But the market's prevailing view is unsentimental: actions must precede announcements. A true re-rating will only materialise when improved profitability and shareholder-return commitments are delivered in practice, not merely declared in principle.
Controversies and structural limitations
*The ₩810bn affiliate bail-out*
A report published on 22nd June 2026 laid out the structural problem at the heart of Hyosung TNC's value-up challenge in blunt terms. The company had channelled approximately ₩810bn into propping up a financially weak chemicals affiliate within the Hyosung Group. The losses from that support were absorbed by Hyosung TNC's general shareholders, yet control of the affiliate remained firmly with the Cho family. Critics described the arrangement as a textbook example of governance risk at family-controlled conglomerates: ordinary shareholders bear the downside while the controlling family retains the strategic upside.
*The pension fund's vote and the limits of activism*
When the National Pension Service opposed the chairman's re-election in March 2026, some voices objected that a state-backed pension fund was overstepping its remit by interfering in corporate management. Institutional investors pushed back, arguing that shareholder activism is precisely what the Value-up Programme demands if it is to have any teeth. The episode crystallised the wider tension in South Korean corporate reform between the rights of controlling shareholders — who have long enjoyed considerable latitude in running family-founded companies — and the interests of minority investors.
*The absence of hard commitments*
Despite the government's Value-up Programme having been in force for well over a year, Hyosung TNC had yet to publish a formal disclosure setting out quantitative targets for its payout ratio, share cancellation programme or return on equity. "A change in management and expressions of intent to improve margins are not sufficient evidence of genuine commitment to value-up," is the recurring complaint from the investment community.
*Structural earnings volatility*
Ultimately, the company's ability to sustain any shareholder-return policy is hostage to the spandex spread. When the cycle is in its favour, as in 2021, profits are exceptional; when Chinese capacity overwhelms demand, as in 2022–23, they evaporate. This structural volatility makes it inherently difficult to offer investors the stable, predictable returns that a serious value-up programme requires.
