A2 Corporation Limited was established in New Zealand in 2000 to commercialise a potentially important discovery relating to further realising the benefits associated with milk. a2 Milk™ is naturally produced to contain maximum amounts of the A2 beta casein protein that a number of studies associate with potential benefits in some individuals.

Listed on the alternative market (NZAX) of the New Zealand Exchange, the company owns and licenses a suite of intellectual property that relates to the identification of cattle and the production and subsequent marketing of a2 Milk™ and related products. The company has entered into business and licensing partnerships to bring a2 Milk™ to the market in New Zealand, Australia, Korea and the United States, and is negotiating arrangements in other markets.

Since 2003, a2 Milk™ has been sold in New Zealand and Australia as a premium brand offering a natural choice in protein content. Consumer response has been very positive, and there has been a growing demand and distribution for A2 products, particularly in Australia. In April 2007, A2 Corporation launched a2 Milk™ into the United States and in October 2007 announced an exclusive license agreement with Lotte Milk Company in South Korea. The product launch is expected to take place in mid 2008.

Although still in its developmental phase, A2 Corporation is sustained by the results of ongoing research by scientific teams worldwide, as well as by remarkable anecdotal reports from consumers that support the beliefs from which a2 Milk™ arose.
