1990–2011: International growth

The first half of the 1990s proved to be favourable for Nestlé. Trade barriers crumbled, and world markets developed into more or less integrated trading areas. Since 1996, there have been various acquisitions, including San Pellegrino (1997), D'Onofrio (1997), Spillers Petfoods (1998), and Ralston Purina (2002). There were two major acquisitions in North America, both in 2002 – in June, Nestlé merged its US ice cream business into Dreyer's, and in August, a US$ 2.6 billion acquisition was announced of Chef America, the creator of Hot Pockets. In the same time-frame, Nestlé entered in a joint bid with Cadbury and came close to purchasing the American company Hershey's, one of its fiercest confectionery competitors, but the deal eventually fell through.

In December 2005, Nestlé bought the Greek company Delta Ice Cream for €240 million. In January 2006, it took full ownership of Dreyer's, thus becoming the world's largest ice cream maker, with a 17.5% market share. In June 2006, Nestlé purchased weight-loss company Jenny Craig for US$600 million. In July 2007, completing a deal announced the year before, Nestlé acquired the Medical Nutrition division of Novartis Pharmaceutical for US$2.5 billion and also acquiring the milk-flavoring product known as Ovaltine, the "Boost" and "Resource" lines of nutritional supplements, and Optifast dieting products.

In April 2007, returning to its roots, Nestlé bought US baby-food manufacturer Gerber for US$5.5 billion. In December 2007, Nestlé entered into a strategic partnership with a Belgian chocolate maker, Pierre Marcolini.

Nestlé agreed to sell its controlling stake in Alcon to Novartis on 4 January 2010. The sale was to form part of a broader US$39.3 billion offer by Novartis for full acquisition of the world's largest eye-care company. On 1 March 2010, Nestlé concluded the purchase of Kraft Foods 's North American frozen pizza business for US$3.7 billion.

Since 2010, Nestlé has been working to transform itself into a nutrition, health and wellness company in an effort to combat declining confectionery sales and the threat of expanding government regulation of such foods. This effort is being led through the Nestlé Institute of Health Sciences under the direction of Ed Baetge. The institute aims to develop "a new industry between food and pharmaceuticals" by creating foodstuffs with preventive and corrective health properties that would replace pharmaceutical drugs from pill bottles. The Health Science branch has already produced several products, such as drinks and protein shakes meant to combat malnutrition, diabetes, digestive health, obesity, and other diseases.

It acquired British pharmaceutical company Vitaflo, which makes clinical nutritional products for people with genetic disorders, in August of 2010. In July 2011, Nestlé SA agreed to buy 60 percent of Hsu Fu Chi International Ltd. for about US$1.7 billion. On 23 April 2012, Nestlé agreed to acquire Pfizer Inc. 's infant-nutrition, formerly Wyeth Nutrition, unit for US$11.9 billion, topping a joint bid from Danone and Mead Johnson.
