- • Flashlight founder and CEO Sanghyun Lee made an all-cash acquisition offer in August valued at 906.6 billion won ($676 million) for Samsung's entire S-1 stake at 116,000 won per share—a 45.2% premium to the prior close—seeking direct communication channels with affiliate shareholders to advance the bid.

Summary
Flashlight Capital Partners, a Singapore-based activist investor, has escalated its engagement with South Korean security company S-1 Corporation by requesting access to shareholder registers held by five Samsung Group subsidiaries that collectively own 20.6% of the firm. According to Reuters reporting on September 9, founder and CEO Sanghyun Lee stated that access to these registers would enable Flashlight to communicate directly with the shareholders of those Samsung affiliates regarding its acquisition proposal. The Straits Times independently confirmed the register request, the Samsung-affiliate ownership block, and the campaign escalation framework.
Flashlight's S-1 engagement began in June 2026 with an initial $40 million stake, representing approximately 2% of S-1's market capitalization. In August, Lee advanced a formal all-cash offer to acquire Samsung's entire S-1 position for 906.6 billion won (approximately $676 million) at a price of 116,000 won per share—representing a 45.2% premium to the prior closing price of 79,900 won. This valuation and premium structure underscores the activist's confidence in S-1's undervaluation and its willingness to deploy significant capital to acquire control of Samsung's affiliate holdings.
S-1's shareholder structure reflects a dispersed ownership base vulnerable to activist pressure. Japan's SECOM remains the largest shareholder at 25.7%, while Samsung's five affiliated entities hold 20.6% collectively. S-1 maintains approximately 11% of shares in treasury, with the remainder distributed among public shareholders. Neither Samsung Group nor any of the five named subsidiaries (Samsung SDI, Samsung Life Insurance, Samsung Fire & Marine Insurance, Samsung Securities, and Samsung Card) responded to the register request or the acquisition proposal. An S-1 corporate spokesperson stated the company has "no position to state" regarding a proposal by one shareholder to purchase shares held by other shareholders, a measured stance that neither endorses nor opposes Flashlight's initiative.
Market participants responded positively to the escalation, with S-1 shares closing up 3.3% at 81,800 won on September 9, signaling investor recognition of potential value creation from activist engagement. The register request constitutes a standard activist tactic designed to circumvent management intermediaries and establish direct dialogue with beneficial owners—in this case, the asset-owning entities within Samsung Group rather than the conglomerate's central holding structure. This remains an ongoing activist campaign with no confirmed outcome, board response beyond no-comment language, or locked tender agreement.
