Does the Israeli Competition Authority review all M&A transactions?

No. Merger notification is mandatory only when the combined annual turnover of the parties in Israel exceeds NIS 150 million AND the target's Israeli turnover exceeds NIS 10 million, under Section 17 of the Economic Competition Law 5748-1988. Deals below these thresholds do not require filing. The Competition Authority has 30 days to issue a decision after a complete filing, extendable to 90 days in complex cases. Closing without approval when notification is required is a criminal offence.
