NEW YORK, Dec. 10, 2025 /PRNewswire/ -- Apple Tree Partners ("ATP"), a 
leading life sciences venture capital firm, has announced that on 
December 9, 2025, certain ATP affiliates filed voluntary petitions for 
Chapter 11 relief in the United States Bankruptcy Court for the District 
of Delaware (the "Court") in order to implement a restructuring plan to 
ensure its portfolio companies have the funding and resources required 
to continue their critical missions to research and develop novel 
breakthrough treatments for cancer, neurological disorders, infectious 
diseases, and other serious diseases. Since its inception more than 25 
years ago, ATP has delivered an industry-leading DPI of 1x on $2.5 
billion. The firm's debut fund, ATP I, stands as the second-highest 
returning fund globally for its vintage (1999). Its most recent fund, 
ATP Life Science Ventures, has best-in-class performance over 12 years 
with a net TVPI of 2.7x and a net DPI of 1.0x. 
 
 
 
   ATP and its affiliates will continue to operate during the 
reorganization. 
 
 
   "We undertake this restructuring to serve the best interests of our 
limited partners, our portfolio companies, their employees and founders, 
the health care professionals and institutions who partner with us in 
researching and developing new medical treatments, and ultimately, the 
patients who stand to benefit from everyone's invention, dedication, 
risk, and effort," said Seth Harrison, M.D., founder and Managing 
Partner, ATP. "We have no doubt that the fundamentals underpinning our 
investments are strong, and that our portfolio companies have shown and 
continue to show great promise to deliver significant returns on 
investment and meaningful new treatments and cures." 
 
 
   ATP has retained B. Riley as financial and restructuring advisor to the 
firm, with Perry Mandarino, Senior Managing Director of B. Riley, as 
Chief Restructuring Officer. Quinn Emanuel Urquhart & Sullivan, LLP and 
Potter, Anderson & Corroon LLP have been appointed general bankruptcy 
co-counsels.
