Tonisity and Elanco Announce Receipt of Permission from the Japanese Government for Tonisity Px Import and Sales
Tonisity and Elanco to Expand Partnership into the Japanese Swine Market.

Dublin, Ireland (January 31st, 2023) – Elanco Animal Health Incorporated (“Elanco“) (NYSE: ELAN), a global leader in animal health, and Tonisity International Limited (“Tonisity“), an animal health and nutrition company based in Ireland, are pleased to announce that they have received the permission from the Japanese Ministry of Agriculture, Forestry and Fisheries (“MAFF“) to import and sell Tonisity Px in the Japanese market.

Having now obtained permission of MAFF to import Tonisity Px into Japan, Tonisity and Elanco are now positioned to immediately accelerate sales of Px into Japan, an important swine market in Asia.

About Tonisity Px

Tonisity Px is a patented isotonic protein drink that directly nourishes the intestinal cells of the small intestines of certain animals, including piglets, which accelerates and increases the absorption of all nutrients into the body of the animal. The result is higher weight gain, lower mortality and less need for medications for these animals – all producing a high return on investment for producers. Tonisity Px is patented in many countries in the world and is currently being sold in Europe, Asia, North America, South America and Australia. Currently, Tonisity Px is manufactured in Ireland.

Swine Market in Japan

The swine market in Japan is one of the most significant in Asia, with approximately 800,000 to 850,000 sows and 9 million pigs.[1] While there is a notable increase in the number of piglets born per litter, Japan still faces a significant challenge in sufficiently reducing Pre and Post Weaning Mortality. Enhancing piglet performance around the weaning stage remains a major hurdle for swine farms in Japan. Tonisity Px presents itself as a vital solution to these current challenges, and we are confident in its ability to contribute to sustainable production in the region.

Distribution in Japan

Further to the joint news release dated November 15, 2022, Elanco and Tonisity entered into a distribution and promotion agreement (the “Strategic Partnership Agreement“) whereby Elanco is responsible for marketing, promotion and distribution of Tonisity Px and Tonisity PxWTM in a number of countries, including Brazil, Belgium, Denmark, France, Germany, Norway, Portugal, Spain, Sweden, and The Netherlands. The Strategic Partnership Agreement was amended in 2023 to include the Japanese market to the exclusive territory, accordingly, Elanco will act as exclusive distributor of Tonisity Px in Japan. As exclusive distributor, Elanco will be responsible for marketing, promotion and distribution and sale of Tonisity Px in Japan.

The addition of Japan to the territory under the Strategic Partnership Agreement represents the parties’ second expansion into the critically important Asian region.

Tonisity intends to ship its first order of Tonisity Px to Elanco in Japan in the near future.

Pablo Muniesa, Elanco Swine & Ruminants International Strategic Growth Initiatives Leader, comments: “Elanco is pleased to be continuing to expand our global commercial relationship with Tonisity International in Asia and across the globe with Tonisity Px. Elanco has a long history of research in intestinal integrity. We believe this expansion into Japan with Tonisity perfectly fits our strategy and complements Elanco’s value offer. We are looking forward to providing our new and existing swine customers in Japan with this innovative product so they can maintain intestinal integrity in their herds and contributing to produce safe, abundant, and affordable food to its population.”

Mathieu Cortyl, Managing Director of Tonisity, comments: “We are so pleased to be expanding our partnership with Elanco into Japan after having received permission from the Government of Japan to sell in this important market. Elanco is one of the most prominent animal health multinationals in the world, and we can think of no better partner to help us to continue the expansion our swine products into Southeast Asia. We are looking forward to helping the agricultural community in Japan increase their bottom lines while improving the gut health of their animals with Tonisity Px.”

About Tonisity’s Swine Products

Tonisity Px is a patented isotonic protein drink that directly feeds the intestinal cells of livestock, such as piglets. This accelerates and increases the absorption of all nutrients into the body of the animal. Tonisity Px is administered to piglets in the first week of life and around weaning and is voluntarily consumed even by newborn piglets. The result is higher weight gain, lower mortality and less need for medications for these animals – all producing a high return on investment for producers.

Tonisity is dedicated to research and has completed nearly 200 swine trials throughout the world. In studies examining pre-weaning morality, Tonisity Px reduced pre-weaning mortality by 20% which amounts to an extra pig for every three litters. Administration of Tonisity Px also resulted in higher weaning weights and 3 kg extra weight at finisher stage, with an improved feed conversion rate. This technology results in a reliable 3:1 return on investment (5:5-1 in a recent China study[2]) at weaning and 5-6:1 at finishing.[3]

Tonisity PxW™ contains the same key bioactives aimed at nourishing the intestine and is delivered through ordinary waterlines to newly-weaned pigs, with no extra labour required. The weaning period and the first 2-3 weeks after weaning are a major danger period for pigs. Often, newly-weaned pigs struggle to maintain sufficient water intake. Reduced water intake correlates to reduced feed intake, which creates a growth lag and contributes to morbidity and mortality.[4],[5]

Tonisity PxW™ improves water intake by up to 2 times in the first few days after weaning. Pigs given Tonisity PxW™ for five days post-weaning had a 36% reduction in post-weaning mortality and a 18% decrease in post-weaning morbidity. Tonisity PxW™ has also been shown to improve end-Nursery weights by 300 grams when compared to a competitor product[6]. Trials indicate that the return on investment on Tonisity PxW™ is a minimum of 4.5:1.

Tonisity’s swine products can also be given to pigs of any age at other stress points in production, such as weaning, before and after transport, and for sows, at farrowing or during lactation. While both products have been demonstrated to improve the performance of healthy pigs, trial data also shows that they are particularly useful in support of dehydration and recovery from illnesses such as Porcine Reproductive and Respiratory Syndrome and Porcine Epidemic Diarrhea Virus.[7]

Tonisity’s swine products are patented in all key markets and are currently being sold in Europe, Africa, Asia, North America, South America and Australia. Currently, the swine products are manufactured in Ireland.
