2021 Employee Stock Purchase Plan financial

"acquisition of the Issuer's Common Stock pursuant to the EPAM Systems, Inc. 2021 Employee Stock Purchase Plan"

Rule 16b-3(c) regulatory

"This transaction is also exempt from Rule 16b-3(c)."

An SEC rule that lets corporate insiders avoid automatic "short‑swing" profit recovery when they buy or sell their company’s stock under a pre‑approved, written plan that meets specific conditions. For investors, it matters because it clarifies when insider trades are treated as routine, reducing legal uncertainty and helping distinguish trades made for ordinary compensation or pre‑planned reasons from those that might signal opportunistic or timely insider advantage.

Purchase Period financial

"for the ESPP purchase period of November 1, 2025 through April 30, 2026 (the "Purchase Period")."
