Activist seeks Samsung shareholder list in fight over S-1 Corp

SINGAPORE, Sept 9 (Reuters) – Activist investor Flashlight Capital Partners has requested the shareholder registers of five units of the powerful Samsung conglomerate that hold a substantial stake in S-1 Corporation, stepping up a campaign to improve ​returns at the South Korean security company.

Sanghyun Lee, the founder and CEO of ‌Singapore-based Flashlight, is seeking to reach out to shareholders of five units of the chaebol that he characterised as exerting outsized influence over S-1, which has lagged behind the returns of the benchmark KOSPI over the past few years.

The five companies – Samsung SDI, Samsung Life Insurance, Samsung Fire & Marine Insurance, Samsung Securities and Samsung ‌Card – ​collectively own 20.6% of S-1 Corp’s shares, according to shareholder ⁠information on its website.

S-1’s biggest shareholder ⁠is Japan’s SECOM, with a 25.7% stake, though Samsung Group usually appoints one of its executives as CEO. S-1 also holds 11% of its own stock as treasury shares, a practice that critics say allows management to exercise a defence against hostile ​takeovers.

“With access to the shareholder registers, we will be able to communicate directly with the shareholders of these five companies,” Lee said.

“These shareholders have a direct interest in ensuring that ⁠their boards properly evaluate our offer and make ⁠the decision that best serves shareholder interests,” he said in a press ​release. “We intend to reach as many of them as possible.”

Samsung Group and its five affiliates did ​not respond to requests for comment. For its part, S-1 said it ‌has “no position to state.”

“This matter concerns a proposal by one of our shareholders to purchase shares held by other shareholders,” a spokesperson for S-1 said.

In June, Flashlight launched a campaign to improve shareholder returns at S-1, revealing a $40 million stake, or about 2% of its market ⁠capitalisation.

Last month, Lee escalated the campaign, offering to buy all of the S-1 shares held by the five units of Samsung Group for 906.6 billion won ($676 million). He also said he has ⁠accumulated a small stake in ‌each of the five Samsung units.

“There is no strategic rationale for ⁠Samsung’s lithium battery and financial-services affiliates to continue holding shares in ​a security-services ‌company given the absence of meaningful business synergies,” Lee added.

When ​Lee, a former ⁠Korea head at The Carlyle Group, submitted a 116,000-won-per-share all-cash offer on August 27, it represented a 45.2% premium over S-1’s 79,900 won closing price a day earlier.

So far, he has made little headway in securing concessions from S-1 and Samsung Group. S-1’s shares opened 0.4% lower at 78,900 won as trading began in Seoul on Wednesday.
