The origins of Mallinckrodt trace back to 1867, when three brothers, Gustav, Otto, and Edward Mallinckrodt Sr., founded G. Mallinckrodt & Co. in St. Louis, Missouri. These German immigrants brought a strong foundation in chemistry, with Otto and Edward having received advanced training in Germany, a nation at the forefront of chemical research during that era. The initial capital investment for their venture was $10,000. The company's initial focus was on manufacturing chemicals to supply local pharmacists, a strategic move that positioned them as the sole chemical company operating west of Philadelphia at the time.

For its initial decades, the enterprise remained privately held and under the control of the Mallinckrodt family, with Edward Sr. and subsequently his son, Edward Jr., leading the company. While specific details regarding equity distribution from the company's inception are not readily available, the concentrated family ownership was instrumental in shaping the company's early strategic direction and product development, including their pioneering work with pharmaceutical chemicals such as morphine and codeine by 1898.

Initially a family-owned business, it became a public company in 1954. The company was acquired by Avon Products, Inc. in 1982, but this ownership was brief, with Avon divesting the company to International Minerals and Chemical Corporation (IMCERA Group Inc.) in 1986.

Over the past three to five years, Mallinckrodt's ownership profile has been significantly reshaped by its financial restructuring. The company filed for Chapter 11 bankruptcy on October 12, 2020, and successfully emerged on November 14, 2023.

Under the terms, Mallinckrodt shareholders are anticipated to hold 50.1% of the combined company on a pro forma basis, with Endo shareholders receiving 49.9% and a $80 million cash payment. The combined entity is expected to be listed on the New York Stock Exchange (NYSE). This transaction is projected to yield at least $150 million in annual operating synergies by year three, reflecting a significant shift in Mallinckrodt stock ownership and strategic direction.

This merger underscores broader industry trends toward consolidation, driven by the pursuit of scale, enhanced financial flexibility, and the capacity to invest in growth opportunities. The pro forma enterprise value of the combined entity is projected at $6.7 billion.
