On Wednesday, outgoing chief executive John Penno told shareholder "we see considerable opportunities to solidify our current ingredient and infant formula positions and to enter new categories."
The CEO, who will step down in the next 12 months, said the company expects demand to increase significantly for Synlait consumer packaged products.
Penno underscored that investing in a second site will support future growth and mitigate risks associated with having a single site.
The company also said it now expects canned infant formula volume to be at the top of the previously advised range of 30,000 - 35,000 MT in the current financial year.
Its key customers include A2 Milk and New Hope Nutritionals.
The shares fell 3.0 per cent at $7.49 and have risen 148 per cent so far this year.
