The filing states the securities were acquired and are held in the ordinary course of business. It further certifies they were not acquired and are not held for the purpose or effect of changing or influencing control of Grid Dynamics, nor in connection with any control-related transaction.

How did the filing calculate Alyeska’s 4.51% ownership of Grid Dynamics (GDYN)?

The reported 4.51% ownership is calculated using 3,782,506 shares beneficially owned divided by 84,769,058 Grid Dynamics common shares outstanding. The outstanding share count comes from Grid Dynamics’ annual report to security holders filed with the Securities and Exchange Commission on November 10, 2025.

The reporting persons disclose zero sole voting and zero sole dispositive power over Grid Dynamics shares. They report shared voting power and shared dispositive power over all 3,782,506 beneficially owned shares, indicating decisions are made jointly rather than by any single reporting person alone.

Why is this Grid Dynamics (GDYN) Schedule 13G/A marked as ownership of 5 percent or less?

Item 5 indicates ownership of 5 percent or less of the class. The reported 4.51% stake in Grid Dynamics common stock falls below the 5% threshold, so the filing acknowledges that the reporting persons’ holdings are under this level while still meeting disclosure requirements.
