While disappointing investors, the company said memory chip demand remained strong.
"Major customers are still requesting more memory supply," SK Hynix President Song Hyun-jong said on an earnings call, adding that it was seeking more long-term supply agreements to better manage chip price volatility.
The move underscores how chipmakers are trying to convert today's AI-driven boom into longer-term demand certainty amid concerns that spending on AI infrastructure could eventually cool.
Long-term agreements include financial safeguards such as deposits to ensure contract implementation. The company has concluded talks on around 10 such deals and is continuing discussions with other major industry players, it said.
The move comes as worries about the ability of "hyperscalers" like Microsoft MSFT.O, Alphabet GOOGL.O, Amazon AMZN.O, Meta Platforms META.O and Oracle ORCL.N to fund hundreds of billions of dollars of planned investment in AI infrastructure have driven down chip shares globally in recent weeks.
Despite those concerns, SK Hynix struck an optimistic note on AI memory demand, saying major technology companies continue to expand investments in AI infrastructure.
"With major tech companies increasing their AI infrastructure investments, additional supply requests continue to mount," the company said. "As these investments are supported by revenue generated from AI services, the momentum in memory demand is expected to persist."
While long-term deals improve visibility over future demand, they may also temper near-term pricing gains, contributing to the earnings miss, analysts said.
SK Hynix also has higher exposure to high-bandwidth memory (HBM) chips, whose prices rose less than conventional memory, they said.
Bigger rival Samsung Electronics 005930.KS has estimated a 19-fold jump in second-quarter operating profit and is due to report its results on Thursday.
"Samsung has greater pricing power and has raised prices more aggressively than SK Hynix," said Lee Su-rim, an analyst at DS Investment & Securities.
