On December 1, following the close of the A-share market, Loongson Technology made an official announcement, revealing that it had secured a win in the second-instance trial of its defamation lawsuit against Shanghai CSI-Chiplink. The roots of this legal battle trace back to March 2021. At that time, Loongson Technology alleged that CSI-Chiplink had disseminated false information via its official website and other public platforms, which not only tarnished Loongson Technology's reputation but also eroded market confidence.

On July 23, 2025, the Beijing Internet Court handed down its first-instance verdict. It mandated CSI-Chiplink to post an apology statement prominently at the top of its official website's homepage for ten consecutive days. Additionally, CSI-Chiplink was required to compensate Loongson Technology for economic losses, encompassing reasonable expenses, totaling 450,000 yuan. Unwilling to accept the outcome, CSI-Chiplink filed an appeal. However, the second-instance court ultimately rejected the appeal and upheld the original decision. The final judgment is expected to have no bearing on Loongson Technology's regular production, business operations, or financial gains and losses.
