SK hynix Says DRAM, HBM Output Effectively Sold Out Through 2029

By Priya Raman

SK hynix (000660.KS) says its dynamic random access memory (DRAM) and high-bandwidth memory (HBM) output is effectively sold out for the next three years, through 2029.

The company made the statement on the 28th during a conference call about its third-quarter results. Its claim combines long-term agreements (LTAs) already secured with contracts now under discussion with customers.

That distinction matters because a negotiation does not yet equal an executed sale. SK hynix did not disclose the split between executed contracts and pending discussions. The 2029 horizon therefore cannot be independently sized from the disclosure.

For customers, the disclosed position leaves little documented room for additional orders during the stated period, subject to pending contracts closing. For investors, it strengthens volume visibility but does not support a price forecast.

What does “sold out” actually cover?

SK hynix did not provide annual shipment volumes, customer allocations, contract prices or a product breakdown between DRAM and HBM. It also did not say whether the wording applies equally to every generation of product or every customer.

Nor did it quantify planned 2029 production or the share reserved for next-generation products. The statement establishes a sales horizon, not a complete physical supply schedule.

In practical terms, the sell-out language indicates that management expects contracts and discussions to absorb available output through 2029, but the disclosure does not establish how binding that coverage will become.

How much capacity is already secured?

SK hynix said: “Volumes secured through LTAs account for more than 50% of total production capacity for next year and 2028, and we plan to keep the share of mid- to long-term LTAs at a similar level.”

That is the statement’s clearest numerical commitment. It covers next year and 2028, rather than the full 2029 horizon. The phrase “a similar level” gives no precise target and does not guarantee the ratio will remain above 50%.

More than 50% is a majority, but it is not equivalent to the full-horizon sell-out claim. SK hynix did not publish the underlying production total, so investors cannot calculate absolute contracted volume. It also leaves the financial effect unquantified.

Why retain capacity outside contracts?

SK hynix said: “While securing a stable earnings base, we also intend to actively build future competitiveness by using the capacity not covered by LTAs to respond to market conditions and demand for next-generation products.”

The company presents contracted and uncontracted capacity as separate tools. LTAs support a stable earnings base; open capacity can respond to market conditions and demand for next-generation products.

That reserve means the sell-out description does not place every available unit under a signed agreement. No minimum share of open capacity was disclosed, however, nor was its intended use quantified by product.

SK hynix did not specify whether next-generation demand would displace existing DRAM or HBM production. The caveat is material because investors receive no measure of that flexibility.

Does the statement guarantee supply through 2029?

No. The sell-out claim depends on signed LTAs and pending negotiations. The disclosure provides no cancellation terms, delivery schedules, added production capacity or customer-concentration data.

The statement also does not show how much output will ship in each year or at what price. The sell-out claim describes the expected contracting position across three years. The numerical commitment applies to next year and 2028.

Neither establishes a three-year revenue or margin forecast. Contracted volume can still depend on execution, product mix and commercial terms that remain undisclosed. Investors should not translate the sell-out wording directly into a fixed earnings amount.

What should investors monitor next?

• The quarterly share of capacity covered by mid- to long-term LTAs.
• Conversion of pending customer discussions into executed contracts.
• The amount and product allocation of capacity remaining outside LTAs.
• Disclosure of 2029 production, delivery coverage, pricing and customer allocations.

Until those data points appear, the statement supports contractual visibility through 2029 but leaves the financial magnitude unquantified. The defensible conclusion is narrower: management expects contracts and pending discussions to absorb available output while preserving a flexible reserve.

The company has not supplied enough detail to test that expectation against annual output, pricing or profitability.
