After-hours trading was relatively quiet Monday, but a handful of names are worth flagging going into Tuesday. CrowdStrike (CRWD) ticked up 2.2% in extended trading after reports of a large enterprise contract win in the financial services vertical. The cybersecurity sector has been a steady beneficiary of rising IT budgets, and CRWD remains a top pick among several sell-side analysts.

Rivian (RIVN) saw a 3.6% after-hours gain following an announcement that it had reached a production milestone of 200,000 vehicles delivered — a significant figure for a company still working toward sustained profitability. The EV maker’s stock has been volatile this year, caught between optimism around its R2 platform launch and concern about cash burn rates. Today’s news is a tangible proof point for the bull case, even if the profitability timeline remains uncertain.

On the downside, GameStop (GME) slid 5.1% in extended trade after a volatile regular session. The stock has been drifting lower since its meme-fueled spike earlier in the spring, and today’s after-hours action suggests no new catalyst to reverse the trend. GameStop’s next quarterly report is due in late June, which will be the real test of whether there’s any operational story underneath the trading activity.
