Record return plans reflect different ownership structures as chipmakers seek lasting stock gains Samsung Electronics flag (left) and SK hynix's Icheon headquarters (Yonhap) Samsung Electronics and SK hynix have unveiled their largest-ever shareholder return programs, moving to share more of the windfall from the artificial intelligence chip boom with investors.The two chipmakers are taking sharply different routes. Samsung is leaning on dividends, while SK hynix is pursuing a massive share buyback and cancellation program — a contrast shaped by their different ownership and financial structures.SK hynix moved first with a 40 trillion won ($28.7 billion) plan to buy back and cancel shares, the largest such program ever announced by a Korean-listed company. The chipmaker plans to complete the purchases by November.Backed by 69 trillion won in net cash as of end-June, SK hynix also raised its shareholder return target from “within 50 percent of cumulative free cash flow” to “50 percent or more,” without specifying the total payout.Samsung followed with a shareholder return program worth 90 trillion to 110 trillion won, combining dividends and share buybacks. At the upper end, the package would be more than five times its previous record of 20.3 trillion won in 2020.Samsung plans to distribute about 30 trillion won in third-quarter dividends, including its regular payout, and return another 60 trillion won to 80 trillion won after finalizing its annual results next January. It separately approved a 15 trillion won buyback to offset dilution from employee compensation.SK hynix bets on buybacks SK Group Chairman Chey Tae-won (center) and other executives pose outside the Nasdaq MarketSite in Times Square, New York, as SK hynix's American depositary receipts begin trading on July 10. (Reuters-Yonhap) For SK hynix, the buyback plan supports the group's ownership structure. Parent SK Square must retain at least 20 percent of the chipmaker under Korean rules for holding companies. Canceling shares automatically raises SK Square's ownership ratio without requiring it to buy more shares, reinforcing its position as the controlling shareholder.The approach also aligns with SK Group Chairman Chey Tae-won's indirect control of the chipmaker through SK Inc. and SK Square. Chey directly owns only 3,620 SK hynix shares that he recently purchased, worth about 4.8 billion won.The cancellation also offsets dilution from the 17.79 million new shares issued for SK hynix's recent Nasdaq American depositary receipt offering, which raised about 40 trillion won for domestic investment. The dollar proceeds and related currency hedging were also credited with helping reverse the won's slide.The strategy effectively allows SK hynix to sell equity at a premium in the US and buy it back more cheaply in Korea.SK hynix said the decision was aimed at strengthening its competitiveness and supporting long-term growth, while noting that its intrinsic value was not fully reflected in the current share price — signaling that the program was also intended to lift its stock valuation.Samsung pays out cash Shareholders check in for Samsung Electronics' 57th annual general meeting at Suwon Convention Center in Suwon, Gyeonggi Province, in March. (Yonhap) Samsung's preference for dividends came as little surprise, given the regulatory and ownership constraints surrounding the company.Under Korea's Act on the Structural Improvement of the Financial Industry, financial companies cannot hold a combined stake of 10 percent or more in a nonfinancial affiliate. Samsung Life Insurance and Samsung Fire & Marine Insurance held 8.51 percent and 1.49 percent of Samsung Electronics, respectively, as of end-June, leaving them right at the 10 percent limit.If Samsung Electronics were to choose share cancellations, it would reduce its outstanding share count and automatically raise the insurers' combined ownership above 10 percent, forcing them to sell shares. Although such sales could generate sizable gains on shares acquired long ago at lower prices, they would shrink the group's affiliated-shareholder bloc and potentially weaken the founding family's influence over Samsung Electronics.Dividends avoid that disruption and offer better tax treatment, as 30 percent of the insurers' domestic dividend income is excluded from taxable income. They also directly benefit Samsung Electronics Chairman Lee Jae-yong and other family members, who hold the shares under their own names.Can record payouts sustain chip rally?Investors initially welcomed the record shareholder return plans, but their longer-term effect on the stocks will depend on whether the two chipmakers can sustain earnings and cash flow through the AI cycle.Samsung Electronics closed 3.87 percent higher at 281,500 won on Friday after touching 285,000 won, although it gave up some gains in after-hours trading. SK hynix rose 2.31 percent to 1.73 million won following its buyback announcement.For Samsung, the large cash payout could strengthen the stock’s appeal to dividend-focused investors and help narrow its valuation discount.“Higher cash returns, including special dividends, could highlight Samsung’s dividend yield and help the stock settle above 300,000 won in the near term,” said Kim Dong-won, head of research at KB Securities. He described Samsung as “a deeply undervalued stock offering both earnings growth and dividend appeal.”For SK hynix, the central question is whether the 40 trillion won buyback marks the start of a longer series of capital returns.Analysts estimate the chipmaker’s cumulative free cash flow over three years at 491 trillion won. At its minimum return rate of 50 percent, the shareholder return pool would exceed 245 trillion won.“This buyback is only an initial deployment,” said Park Jun-young, an analyst at Hanwha Investment & Securities. Additional buybacks exceeding 100 trillion won could progressively reduce the number of outstanding shares and increase earnings and value per share, he added.The immediate direction of both stocks, however, may still be shaped by broader conditions affecting the AI chip rally, including Nvidia’s earnings and US Treasury yields.
