14 men are convicted of murder, conspiracy to commit terrorism and weapons offences, among other charges. A 15th defendant is found guilty of some of the charges, while nine others are acquitted.
The sentencing will take place later.
The 2019 Easter bombings killed 279 people, including the perpetrators, and injured another 500 in attacks targeting luxury hotels and churches, among other places. The coordinated suicide attacks were the deadliest in Sri Lanka since the end of the civil war in 2009.
Among the men now convicted are relatives and associates of the nine suicide bombers. A domestic Islamist extremist group has been singled out as ultimately responsible.
