Goldman Sachs has entered the electric vertical takeoff and landing (eVTOL) sector with its first round of stock ratings. The firm initiated coverage with a "Buy" rating for Beta Technologies (BETA.US), "Neutral" ratings for Archer Aviation (ACHR.US) and Eve Holding (EVEX.US), and a "Sell" rating for Joby Aviation (JOBY.US). Analyst Anthony Valentini highlighted that technological advancements and the current administration's push to reshore manufacturing have improved visibility for eVTOL certification timelines.

"While competition is intense, we don’t view this as a winner-takes-all market," Valentini noted. "We favor business models with strong aftermarket profitability, vertical integration, revenue visibility, and the ability to meet future demand." Below is Goldman Sachs' detailed analysis of each eVTOL stock:

**Beta Technologies (Buy Rating):** "Beta’s phased certification approach via CTOL aircraft allows early revenue generation and accelerates the learning curve without disrupting its eVTOL timeline. As both an aircraft OEM and parts supplier—one of the most attractive business models in aviation—Beta has partnered with GE to develop a hybrid aircraft for defense applications. Its collaborative approach, including selling motors and chargers to competitors, supports scalability. We believe Beta is best positioned, and the recent stock decline offers an attractive entry point."

**Joby Aviation (Sell Rating):** "Joby is the longest-standing player in the space with the most flight hours and a lead in certification. While its ambition to be a full-service provider (manufacturing, supply, and operations) offers the largest market opportunity, we see regulatory hurdles and significant capital requirements as key challenges. The stock trades at a substantial premium, which we view as unjustified."

**Archer Aviation (Neutral Rating):** "Archer’s outsourcing strategy has accelerated its certification timeline despite being a newer entrant. Its aircraft’s size suggests strong performance potential. However, lack of vertical integration limits aftermarket profitability, likely resulting in lower margins. Its partnership with Anduril could yield the best defense product in the sector, but valuation remains unclear due to limited funding visibility."

**Eve Holding (Neutral Rating):** "Embraer’s controlling stake provides advantages in workforce, facilities, and aviation expertise. However, this structure has slowed Eve’s development pace, resulting in fewer flight hours. We expect the company to compete eventually but note its relative lag in certification progress."
