Magna International's stock plummeted 5.39% during intraday trading on Friday, as investors reacted negatively to the company's revised full-year sales outlook despite a strong first-quarter earnings beat.

The automotive supplier reported quarterly adjusted earnings of $1.38 per share, significantly exceeding analyst estimates of $1.01, while sales of $10.38 billion also topped expectations. However, management lowered its 2026 sales guidance to a range of $41.5 billion to $43.1 billion from the previous forecast of $41.9 billion to $43.5 billion.

The guidance reduction reflects more conservative assumptions for light vehicle production in North America and Europe, with the company now expecting 14.9 million units in North America (down from 15.0 million) and 16.6 million units in Europe (down from 16.8 million). CEO Swamy Kotagiri emphasized the company's "disciplined execution, margin expansion and robust free cash flow generation" in the first quarter, but the revised sales target appears to have overshadowed the positive quarterly results in investors' assessment.
