Ann: Entry into Manufacturing Agreement with Sprout Organic, page-38

It isn't commercially viable though, that's the point. It will cost too much for both companies to extract any margin. And something is only commercially viable if both are able to.

Take a look at Synlait Pokeno for instance. They tried dual production but found it so inefficient that they have had to switch to plant-based only (one difference being that they have a large plant-based customer with actual orders).

From an article reporting on their review:
"One of the review’s findings was that switching between processing plant-based proteins and dairy hinders the Pōkeno plant’s operational efficiency."

And Pokeno is a much newer facility which has also invested significantly into upgrading to cater for plant-based. AHF was never designed for it and has not upgraded anything.
