Will union strike, insider trading probe weigh on Samsung Electronics shares?

Market attention is increasingly focused on how a convergence of internal labor tensions and external legal risks surrounding Samsung Electronics could weigh on its share price trajectory, industry analysts said Thursday.
A key challenge is the prospect of a labor strike, with the company’s union signaling a general walkout for the first time in nearly two years, raising the risk of renewed friction between management and workers.
The tech giant’s joint union announced Wednesday that it formally secured strike authorization after winning 93.1 percent support in a vote.
It plans to kick off its campaign with a rally on April 23, followed by a full-scale strike in May, pressing for reforms to the performance-based pay system and broader improvements in compensation.
The union’s core demands for the 2026 wage talks include clearer criteria for calculating bonuses, the removal of caps on incentive payouts and a 7 percent pay raise.
Should the strike materialize, it would mark only the second in the company’s history since its founding in 1969, after the first in July 2024, adding symbolic weight that could dampen market sentiment.
Compounding the labor issue is a growing legal risk tied to a prosecution probe into allegations of insider trading involving non-public information.
State prosecutors have launched an investigation into suspected insider trading linked to Samsung’s acquisition of Rainbow Robotics.
Prosecutors are examining whether insiders and related parties at the robotics firm used undisclosed information to secure illicit gains during the deal. As part of the probe, investigators have searched the company’s headquarters and the residences of individuals involved as well as Samsung’s operations in Suwon, Gyeonggi Province.
The case stems from a referral by the Financial Services Commission. Last month, the regulator referred 16 individuals, including the robotics firm’s CEO and former finance chief, to prosecutors on allegations of violating capital market laws.
The suspects are accused of generating about 3 billion won ($2 million) to 4 billion won in illegal profits by trading on undisclosed information during share purchases carried out between 2022 and 2024.
Market participants note that if the insider trading allegations are substantiated, confidence in Samsung’s governance and internal controls could be undermined, potentially weighing on its stock price.
With both labor tensions and legal uncertainties unfolding simultaneously, the company’s ability to manage and resolve these issues is expected to be a key determinant of its near-term share performance.
Most analysts believe the immediate impact of a strike on Samsung’s output and earnings will likely be limited. However, they warn that if the walkout is prolonged while inventory levels remain low, any disruption to output could quickly translate to lost sales.
“Samsung’s semiconductor plant utilization rate is currently only around 70 percent. The company is intentionally cutting production, which is why prices are rising. Data from last October and this January, when prices surged, show that output fell by about 20 percent month-on-month. If Samsung normalizes production, prices would likely decline. Given this deliberate production cut, a union strike is unlikely to pose a major problem,” said Lee Ju-wan, an industry analyst who previously served as a research fellow at POSCO Research Institute and the Hana Institute of Finance.
“However, with inventories currently at low levels, any real disruption to production could immediately lead to sales losses due to the lack of buffer," Lee said.
