# Mastellone Hermanos corporate restructuring > Live situation record from CLSTR: https://clstr.news/situations/mastellone-hermanos-corporate-restructuring > Updated: 2026-09-02T02:24:15.000Z. Sources: 8. Developments: 2. Mastellone Hermanos, a leading Argentine dairy company, has undergone a significant financial and structural reorganization involving Arcor and Danone. Initially, Arcor and Danone planned to inject US$30 million into Mastellone Hermanos through their joint venture, La Serenísima Unida S.A. (LSU), to settle bank debt and strengthen the company’s financial position following a period of high liabilities and bond maturities. Following these developments, the company’s credit rating was upgraded to AA.ar by Moody’s Argentina for long-term local and foreign currency obligations. This upgrade was attributed to a change in shareholding structure and reduced leverage, as Mastellone is now controlled by Arcor and Danone’s Argentine subsidiary. The restructuring includes the formal operation of the LSU joint venture, which integrates Mastellone, Danone, and Logística La Serenísima. While the company reported a loss of $4,791 million for the first half of 2026 and a decline in domestic sales, export revenues grew by 10.5% during the same period. ## Timeline ### 2026-09-02: Mastellone Hermanos receives credit upgrade amid Arcor and Danone takeover Mastellone Hermanos received a credit rating upgrade following its takeover by Arcor and Danone, despite reporting a loss and declining domestic sales in the first half of 2026. 5 sources. https://clstr.news/cluster/mastellone-hermanos-receives-credit-upgrade-amid-arcor-and-danone-takeover ### 2026-08-27: Arcor and Danone to inject US$30 million into Mastellone Hermanos Arcor and Danone will inject US$30 million into Mastellone Hermanos via their joint venture to pay down bank debt and improve the company's financial solvency. 3 sources. https://clstr.news/cluster/arcor-and-danone-to-inject-us30-million-into-mastellone-hermanos --- Cite as: Mastellone Hermanos corporate restructuring.
