Lino Industry has encountered a significant variable—an indefinite general strike, the first since the company's founding—amid a streak of record-breaking performance. Driven by growing demand for semiconductor test pins and sockets, the company achieved its highest-ever performance in 2025, followed by an operating profit margin of approximately 47% in the first quarter of 2026. However, concerns are mounting that the prolonged general strike, which began in July, could disrupt production schedules and create burdens in the transition to a new factory scheduled for operation in the second half of the year.

[Record-Breaking Performance Streak]

According to preliminary earnings disclosures published on the Korea Exchange (KRX) electronic disclosure system, Lino Industry's revenue for the first quarter of 2026 reached KRW 99.771 billion, up 27.2% year-on-year. Operating profit stood at KRW 47.301 billion (up 35.4%), while net income reached KRW 40.396 billion (up 37.7%). The simple operating profit margin of approximately 47.4%, with operating profit growth outpacing revenue growth, demonstrates the sustained high profitability driven by high-value-added semiconductor test components.

The 2025 performance also reached an all-time high. According to corporate analysis data compiled by the Korea Investors Relations Council based on Lino Industry's business report, 2025 revenue amounted to KRW 372.5 billion (up 33.9% year-on-year), with operating profit reaching KRW 177 billion (up 42.5%).

Lino Industry's flagship products are Lino Pins and IC test sockets used in the electrical performance testing of semiconductors. According to the business report submitted to the KRX, the company operates businesses in semiconductor test components and medical device components, and manages key performance indicators such as revenue growth rate, operating profit achievement rate, new model revenue share, and on-time delivery rate.

[General Strike Triggered by Performance-Sharing Dispute]

The escalation of labor-management disputes amid robust performance has become a new focal point for market observation. According to Yonhap News Agency, the Lino Industry labor union began rotating partial strikes by department on July 20, before entering an indefinite general strike on July 23. Mediation by the Busan Regional Labor Relations Commission broke down on July 13, enabling the union to secure legal dispute rights.

The first negotiation since the start of the general strike was held on July 30 but ended without an agreement. According to Yonhap News, the two sides negotiated for over seven hours on the issue of performance bonuses but failed to narrow their differences. The union demanded a 400% regular bonus and 300% in performance-based pay for each half of the year. Meanwhile, the company proposed a 700% first-half management performance bonus, along with a separate package that included a 300% management performance bonus, an additional base salary increase, holiday bonuses, and various allowances.

Yonhap News reported that approximately 340 of the 665 employees scheduled to work participated in the strike, accounting for more than half of the workforce on duty. Newsis reported that since the Lino Pin and socket production process flows sequentially from raw material processing to assembly and inspection, a work stoppage at even a partial stage of the process could affect the entire production flow. However, specific production reduction volumes and revenue loss figures are not confirmed disclosure numbers, so the actual impact must be verified through future earnings reports.

[KRW 200 Billion New Factory Schedule Could Also Be Affected]

Another reason the strike is drawing attention is the company's push for large-scale production capacity expansion. According to an announcement by the City of Busan, Lino Industry is investing a total of KRW 200 billion to build a new semiconductor factory in Busan Eco Delta City. Targeting operation in the second half of 2026, the facility is being developed on a 72,519-square-meter site—approximately twice the size of the existing factory—with a total floor area of 69,525 square meters, and the company also plans to hire approximately 200 new employees. The investment aims to consolidate scattered production facilities and expand production capacity for semiconductor test components.

If the general strike is prolonged, it is expected to affect not only the operation of existing production lines but also the deployment of personnel to the new factory, equipment relocation, and mass production stabilization schedules. However, this is an inference based on the currently disclosed production structure and the new factory schedule; the company has not officially announced any delay in the new factory's operation.

[Largest Shareholder's 9.18% Stake Sale Also a Variable]

The largest shareholder's large-scale stake sale is another factor that has increased stock price volatility this year. According to a Yonhap News report citing the Financial Supervisory Service's electronic disclosure system, CEO Lee Chae-yoon disclosed a plan in April to dispose of 7 million shares (9.18% of total issued shares) through an after-hours block trade. The estimated transaction value at the time of disclosure was KRW 863.1 billion, with the purpose of the disposal stated as asset management through the sale of shares.

Following the actual disposal of 7 million shares, CEO Lee's holdings decreased from 26,418,345 shares to 19,418,345 shares, bringing the stake down from 34.66% to 25.48%. However, the CEO maintains the position of largest shareholder.

[Future Points to Watch]

The core issue surrounding Lino Industry is not simply the occurrence of the strike itself. Given the record-breaking performance in 2025 and a roughly 47% operating profit margin in the first quarter of 2026, the critical question is whether the conflict over performance distribution will translate into production disruptions. Whether the second-half operation schedule for the new Eco Delta City factory, backed by a KRW 200 billion investment, will be maintained, and to what extent production delays during the general strike have affected order fulfillment and delivery times, are points that must be verified in future quarterly reports.

Lino Industry has secured growth drivers in the form of expanding semiconductor test component demand and production capacity increases. However, following the largest shareholder's massive stake sale and compounded by the company's first-ever general strike, the market's evaluation criteria are broadening beyond technological prowess and financial performance to include the prospects for labor-management agreement and production normalization.
