Emery, a former Arsenal, Sevilla and Paris St-Germain boss, joined Villa in 2022 from Villarreal.
In his time at Villa he has transformed the side, from a group who were in a relegation fight to one who have qualified for European football every season under his management.
The plan is to announce the new contract once all details have been agreed, which is unlikely to be before the weekend.
The objective is clear: to build an ambitious, competitive Aston Villa capable of taking on the biggest challenges and achievements.
Talks are ongoing about the fine details, the finances and the length of the new agreement.
Emery would relish the opportunity to play an even bigger role in developing the club for the long term.
Aston Villa manager Unai Emery is close to agreeing a contract extension at the club.
Villa intend to confirm the extension only after the remaining terms are settled.
Emery, already under contract until 2029, is now close to signing a new longer-term deal.
The former Villarreal coach has overseen European qualification in every season since arriving in 2022.
