Rivian Automotive's stock surged 17.14% in pre-market trading, reflecting a significant positive reaction from investors following the company's latest financial results and future outlook.

The electric vehicle maker reported better-than-expected fourth-quarter 2025 results, with an adjusted loss per share of $0.54 beating the consensus estimate of a $0.68 loss. Revenue of $1.286 billion also exceeded analyst expectations. Furthermore, Rivian provided optimistic guidance for 2026, forecasting vehicle deliveries between 62,000 and 67,000 units, representing approximately 53% growth over 2025 levels.

Investor enthusiasm is largely driven by the progress of Rivian's more affordable R2 SUV, which remains on track for first customer deliveries in the second quarter of 2026. The R2 is seen as a critical catalyst for expanding beyond the company's premium vehicle lineup and attracting a broader customer base with its lower price point starting around $45,000.
