📊 SK hynix, at the Intersection of HBM Competition, Exchange Rates, and Labor Variables - 2026.09.13

Hi, it’s Dotori. On September 13, I see SK hynix’s key issue as the simultaneous emergence of the link between HBM competition and earnings, exchange-rate factors, and labor-management variables. On one side, securities firms expect next-generation HBM leadership to determine second-half earnings, while on the other, the labor-management agreement and revised incentive plan have returned to the ballot. This is not a scene where only one semiconductor gear is turning.

🔗 The Big Picture Is HBM4; the Short-Term Variable Is the Exchange Rate

South Korean securities firms forecast that Samsung Electronics’ and SK hynix’s earnings in the second half of 2026 could vary depending on leadership in next-generation HBM [2]. This is not earnings or a plan confirmed by the companies, but a conditional assessment from the securities industry. Even so, when viewing SK hynix within the broader AI memory industry, it means the HBM4 competition has become an observation point for earnings differentiation, rather than merely a product announcement.

Meanwhile, Herald Economy reported that earnings forecasts for Samsung Electronics and SK hynix were adjusted as the KRW/USD exchange rate fell to the 1,340 KRW range [3]. An exchange rate alone does not change memory demand, but it can act as a variable that shakes earnings forecasts even under the same sales and cost structure. Looking one step deeper, a picture focused only on HBM competitiveness is too flat; the external variable of exchange rates must be layered in as well.

⚙️ The Yongin Fab Is the Supply Chain’s Next Gear

On September 12, Money Today Broadcasting covered related beneficiaries, saying that construction of SK hynix’s first Yongin fab is gaining momentum [5]. The provided material does not confirm specific investment amounts or a completion date, but because fab construction is linked to the company’s medium- to long-term production base, it offers a way to broaden the HBM competition into a supply-chain perspective.

If we deliberately divide the differentiated benefits across the industry’s value chain, first priority is HBM4 competitiveness, second priority is the production base connected to construction of the first Yongin fab, and third priority is the personnel and security systems that prevent technology leaks. This order is not an investment judgment, but the priority for observing the industry linkages revealed in this material. In relay terms, HBM is the lead runner, while the fab and security are the sections that keep the baton from being dropped.

🏭 Labor-Management Agreement Is a Variable Outside Earnings

SK hynix’s wage and collective bargaining agreement overturned the previous result by a margin of 25 votes, and attention is focused on the possibility that the revised incentive plan may go to a vote again [1]. The confirmed facts here extend only to the voting result and the status of renewed discussions. It is difficult to go further and state as confirmed whether the revised plan will pass or how the company’s subsequent cost structure will change.

Still, semiconductor companies do not run on technology and facilities alone. Retaining employees and reaching consensus within the organization are also pillars of the production system. Thus, although this issue is less eye-catching than HBM4 or fab news, it remains a separate variable for assessing whether the supply-chain gears are meshing smoothly.

📚 On the Other Side of the Technology Race: Leakage Risk

A September 13 report pointed out that semiconductor technology leaks and personnel movement could continue even with South Korea expanding its espionage laws, and also mentioned China’s semiconductor pursuit and related cases [4]. The market-share figures cited in the article lack sufficient grounds for comparison with other materials, so I will leave them out here.

Dotori believes the securities industry’s outlook that HBM4 leadership is the central axis of earnings differentiation remains valid, but it must be viewed separately from results confirmed by the company. The questions ahead are clear: whether next-generation HBM competition will lead to actual earnings differences, whether construction of the Yongin fab will translate into a stronger production base, and what friction exchange rates, labor-management relations, and technology security variables will create in that flow.
