Is Tesla Still the EV King?

Tesla reported a challenging Q1, with revenue down 9% to $19.3 billion and adjusted EPS down 50% to $0.27, alongside contracting gross margins to 16.3%, driving a 25% share decline in 2025 and a Zacks 'Strong Sell' rating. In contrast, Rivian shares have gained 2% in 2025, reporting a record quarterly gross profit of $206 million and experiencing positive EPS revisions, signaling a more favorable outlook despite its smaller scale. This divergence highlights shifting dynamics in the EV sector, with profitability pressures impacting established players while challengers show improving fundamentals.

Analysis

A significant divergence in fundamental momentum and investor sentiment is evident between Tesla (TSLA) and Rivian (RIVN). Tesla is facing considerable headwinds, evidenced by a 25% share price decline in 2025, a 9% year-over-year drop in Q1 revenue to $19.3 billion, and a 50% contraction in adjusted EPS to $0.27. The primary concern is eroding profitability, with gross margins shrinking to 16.3%, which has triggered widespread negative EPS revisions and a Zacks Rank #5 (Strong Sell) rating. While its Energy Generation & Storage segment sales grew 67%, this was insufficient to offset the weakness in its core automotive business. In stark contrast, Rivian's stock has gained 2% over the same period, supported by improving operational metrics. The company achieved a record quarterly gross profit of $206 million and met its production and delivery guidance, a key sign of execution. Despite revising its full-year delivery forecast to 40-60k vehicles, the earnings outlook remains bullish, with the consensus EPS estimate revised upward by 14%, signaling growing confidence from analysts.

Key Decisions for Investors

• Given Tesla's declining revenue, contracting gross margins, and strongly negative analyst revisions, investors should approach the stock with caution, waiting for evidence of stabilizing profitability and a reversal in sentiment before initiating new long positions.
• Rivian's positive EPS revisions and achievement of record gross profit present a more favorable fundamental picture; investors could consider its outperformance as a signal of strengthening execution, while closely monitoring its ability to meet revised delivery targets.
• The clear divergence in performance and outlook between the two companies suggests a potential relative value strategy; a pairs trade, going long RIVN and short TSLA, could be considered to capitalize on the contrasting momentum and analyst sentiment.
