After-hours movers: AMD, SMCI, GOOGL, AVTX, ANET, UPST, TEM

After-hours movers showed a mixed market reaction to earnings, guidance and clinical news. AMD (primary instrument) jumped after a beat-and-raise quarter with Q1 EPS of $1.37 and revenue of $10.25B and upbeat Q2 guidance of $11.2B. Super Micro Computer rallied on a strong earnings beat and an aggressive Q4 2026 outlook (revenue $11–$12.5B, EPS $0.65–$0.79). AVTX surged on positive Phase 2 trial results for a hidradenitis suppurativa drug. Alphabet gained after reports that Anthropic will spend about $200B with Google Cloud over five years. Conversely, Upstart, Arista and Tempus sold off as they only met — but did not exceed — expectations or issued tepid guidance, prompting profit-taking. Overall the piece highlights company-specific catalysts driving after-hours volatility rather than a broad market theme.
