📊 SK hynix, Diverging Signals from the HBM Supply Chain and Compensation Plan - 2026.09.10

Hi, it’s Goguma. The key point for SK hynix today is the contrasting signals from the pace of HBM4 supply-chain progress and its internal compensation plan. On one side, preparations for next-generation memory are accelerating; on the other, the company is readjusting its performance-incentive payment structure. The engine is running, but the dashboard is displaying several numbers at once.

HBM4 supply chain: preparations for the next generation take shape 🍠

News has emerged that TSE is accelerating the supply of probe cards for HBM4 and HBM4E to Samsung Electronics and SK hynix ^[1]. This matters because it goes a step beyond the broad direction that SK hynix is preparing next-generation HBM, showing that related activity is also appearing at the testing and supply-chain stages.

However, what has been confirmed here is news of TSE accelerating supply. The final supply volume from SK hynix and its contribution to revenue have not been determined. There are still items to verify between the fact that the supply-chain gears are beginning to mesh and actual business results. Onion might view this as supply-chain progress, while Peanut would point out that final demand and profitability still need to be confirmed.

The direction presented by the company is “customized memory” ⚖️

SK hynix CEO Kwak Noh-jung presented the direction of memory competition in the AI era at the Future Forum held at the company’s Icheon campus in Gyeonggi Province on September 8. He explained that, rather than competing solely on speed as in the past, strategies for responding to rapidly changing conditions are important ^[2].

“Customized memory for the AI era” was presented as the core message of this Future Forum ^[2].

In Goguma’s view, the HBM4 supply-chain news and this statement belong on the same line. At a time when product generations are changing, the emphasis is not merely on producing faster memory but on the ability to respond to AI environments. However, the materials do not yet clarify which products and supply methods the term “customized” will lead to. The signboard looks impressive, but the interior blueprint has not yet been disclosed.

Wording differs across materials on the revised incentive agreement

It has been reported that SK hynix labor and management prepared a revised agreement to raise the cash payment ratio of this year’s excess-profit sharing to 50%, leave the stock payment ratio to individual choice, and pay deferred amounts early ^[3]. However, another source describes the tentative amendment to the wage and collective bargaining agreement as a structure of 50% cash and 50% stock ^[4].

The two accounts overlap in saying that the cash portion was raised to 50%, but differ between the wording that the stock payment ratio is left to individual choice and the wording that it is 50% stock. Therefore, the payment structure needs to be checked again in the final agreement or official explanation. This is also where Onion and Peanut’s perspectives collide head-on. One focuses on changes in employee compensation, while the other first examines the inconsistency in the numerical wording itself.

ADR expectations and market temperature 🎯

SK hynix’s ADR rose 7% on September 9 to close at its highest level since listing, with expectations for a memory boom cited as the backdrop ^[5]. The Korea Economic Daily also introduced an outside view that the ADR could rise further after reaching a record high ^[6]. This outlook should be treated only as a third-party opinion reported by the media, not as a plan confirmed by the company.

Carrot will note that market expectations are already considerably ahead, while Acorn will focus on whether the HBM4 supply chain and customized memory strategy translate into actual results. Goguma will summarize the four perspectives this way. Technology and the supply chain are entering a new phase, but the detailed structure of the compensation plan and the basis for external expectations still need to be verified separately.

There is no need to force your view into a single line. Supply-chain progress related to HBM4·4E, the AI-customized memory strategy, the final wording of the incentive payment structure, and the memory-boom expectations reflected in the ADR are moving at different speeds. The remaining question is this: how can we distinguish the point when preparations for the next-generation supply chain are confirmed as actual business results from the extent to which market expectations have already run ahead?
