Movio focuses on big data analytics through the collection of information from cinemas, and the deal would mean its products will be installed across AMC's 347 locations and 4972 screens in the US.
Founded in 1920 in Kansas, AMC (American Multi-Cinema) has more than 200 million customers annually.
Vista Entertainment bought an initial 30 per cent stake in Auckland-based Movio four years ago before increasing it to 56 per cent last year.
This gave Vista a commanding share in the business, after a year where Movio grew its revenue by 311 per cent and increased staff numbers from seven to 27.
Movio co-founder William Palmer said at the time of the acquisition that working with Vista had helped the company to expand.
"Building the partnership with Vista has been great, it's opened a lot of doors for us and now we have a symbiotic relationship where working together means we can tap into two markets not just one."
Movio collects information on a large scale, according to Palmer, with 90 per cent gathered at point-of-sale.
The data is used to help the cinema industry target movie campaigns - a part of sector which he said was worth more than $20 billion a year.
