Investment Thesis With a diversified portfolio of drugs, Amphastar Pharmaceuticals Inc. (AMPH) is continuously operationalizing its drugs that receive FDA approval and filing new applications. With 3 ANDAs under review by the FDA and seven more under development, AMPH has promising growth prospects in 2H2022 and beyond. Furthermore, with recent approvals, AMPH can anticipate nearly doubling its revenue by the end of 2023 with proper operationalization and execution of the approved drugs.

Background Amphastar Pharmaceuticals, Inc. is a diversified drug manufacturer that produces various products, including injectibles, biosimilars, complex generic, inhalation, and proprietary products. The main product lines operated by Amphastar are as follows: Enoxaparin: an anticoagulant that prevents blood clots. This drug is abbreviated Enox. Lidocaine Injection and Jelly: Helps reduce patient discomfort during peripheral nerve blocks. Vitamin K1: vitamin K1, obtained from leafy greens and other vegetables, is used to prevent blood clots. Primatene Mist: FDA-approved asthma inhaler is projected to add $100 million to sales by the end of 2024, with an annualized growth rate of 34%. The success is mainly attributable to the physician sampling program and national TV and radio marketing campaigns. Glucagon: Glucagon is a hormone that prevents blood sugar from becoming too low. It is a mature product for Amphastar and is projected to have a positive trajectory in terms of sales and growth. Epinephrine: This drug is used to treat life-threatening allergic reactions. Like glucagon, this product is on a continued growth trajectory for the foreseeable future. This drug is abbreviated "Epi." in the chart below. Naloxone: Similar to suboxone, Naloxone is used to reverse opioid overdose. Naloxone is the second half of suboxone designed to reverse overdoses. Naloxone is also non-addictive because it only works if the person has opioids in their system. The relative contribution of these medications to the overall portfolio of AMPH is shown below.
