Brochure Summary

Overview

PAI is the investment adviser to private pooled investment vehicles, the securities of which are offered to investors on a private placement basis (each a “Fund” and collectively, the “Funds”). Its principals and the leaders of its portfolio team are Dr. A. Joon Yun and Dr. Patrick Lee. PAI was previously Palo Alto Investors, LLC, a California limited liability company. On March 30, 2018, it converted into a California limited partnership. At the same time, it organized its affiliate, PAI LLC, a California limited liability company with which it is under common control, to act as the general partner of the Funds that are organized as limited partnerships, and PAI entered into an Investment Adviser Agreement with each of the Funds pursuant to which it manages their assets. PAI was founded by William L. Edwards. While Drs. Yun and Lee have led portfolio management team for some time, until December 31, 2012, Mr. Edwards was PAI’s chairman, chief executive officer and chief investment officer, and the chairman, chief executive officer and sole shareholder of Palo Alto Investors,

a California corporation that served as its manager. Effective as of January 1, 2013, Mr. Edwards transitioned the management of PAI to Drs. Yun and Lee. In connection with that transition, Drs. Yun and Lee replaced Palo Alto Investors as the co- managers of PAI and Mr. Edwards resigned as the PAI’s chairman, chief executive officer and chief investment officer. As of December 31, 2023, PAI had total discretionary assets under management of approximately $1.06 billion. PAI manages assets only on a discretionary basis. PAI invests principally, but not exclusively, in equity and equity-related securities that are traded publicly in U.S. markets and issued by companies primarily in the healthcare industry. Regardless of its current focus, for each of the Funds, PAI is authorized to enter into any type of investment transaction that it deems appropriate under the terms of each Fund’s partnership or investment agreement. The investors in the Funds have no opportunity to select or evaluate any Fund investments or strategies. PAI selects all Fund investments and strategies.
