Core Viewpoint - Goldman Sachs has initiated stock ratings in the eVTOL industry, providing a "Buy" rating for BETA Technologies, "Neutral" ratings for Archer Aviation and Eve Holding, and a "Sell" rating for Joby Aviation [1][2] Group 1: BETA Technologies - BETA Technologies is rated "Buy" due to its phased certification process through CTOL aircraft, which allows for early revenue generation and accelerated learning without affecting the eVTOL timeline [1] - The company operates as both an aircraft manufacturer (OEM) and a parts supplier, representing an attractive business model in the aviation industry [1] - BETA has partnered with General Electric (GE) to develop a hybrid aircraft for defense and is collaborating with competitors to sell motors and chargers, aiding in scaling [2] Group 2: Joby Aviation - Joby Aviation is rated "Sell" as it is the oldest company in the sector with the most flight hours and leads in certification [2] - The company aims to be a one-stop service provider covering manufacturing, supply, and operations, which presents the largest market opportunity [2] - However, Joby faces regulatory hurdles and significant capital requirements, and its current stock price is considered to be at a significant premium, which is deemed unreasonable [2] Group 3: Archer Aviation - Archer Aviation receives a "Neutral" rating, with its outsourcing approach accelerating certification despite being younger than competitors [2] - The size of its aircraft may indicate strong performance, but the lack of vertical integration suggests lower aftermarket profits and margins [2] - Archer's partnership with Anduril could lead to a top defense product, but the lack of funding visibility makes it difficult to assess its value [2] Group 4: Eve Holding - Eve Holding is rated "Neutral," with its parent company Embraer's control providing attractive labor, facilities, and aerospace expertise [2] - This structure, however, results in slower development and fewer flight hours [2] - The company is expected to compete in the market eventually, but it is currently lagging in certification [2]
