U.S. stock futures are trading lower Tuesday morning, but that's not stopping a handful of companies from grabbing the spotlight with their latest earnings reports. Here's what's moving and what to watch as the market opens.

Before the Bell

Duluth Holdings Inc. (DLTH) is expected to report a quarterly loss of 46 cents per share on revenue of $118.50 million before markets open, according to data from Benzinga Pro. Despite the anticipated loss, Duluth shares climbed 5.4% to $3.30 in after-hours trading, suggesting investors may be positioning for a less-bad-than-expected report.

After-Hours Winners and Losers

B. Riley Financial Inc. (RILY) delivered one of the more dramatic turnarounds in recent memory. The company posted earnings of $4.50 per share for the second quarter, a stark contrast to the $14.35 per share loss it reported in the same quarter last year. Revenue more than doubled, surging to $225.3 million from $94.9 million a year ago. Investors loved it—shares rocketed 30.4% higher to $4.85 in after-hours trading.

On the flip side, Navan Inc. (NAVN) showed what happens when guidance disappoints, even if the quarter itself looks solid. The company reported upbeat third-quarter results but then dropped a bombshell: it now expects fiscal 2026 sales of just $685 million to $687 million, dramatically below the $830.87 million analysts had been modeling. That's a big miss, and the market reacted accordingly. Navan shares tumbled 7.7% to $13.51 after hours.

Still to Come

Analysts are looking for Worthington Enterprises Inc. (WOR) to deliver quarterly earnings of 70 cents per share on revenue of $310.60 million when it reports after the closing bell. Worthington shares fell 0.7% to close at $57.74 on Monday, setting up a relatively neutral starting point for the report.

Meanwhile, homebuilder Lennar Corp. (LEN) is also scheduled to report after the market close, with analysts expecting earnings of $2.21 per share on revenue of $9.02 billion. Lennar shares edged up 0.1% to $119.90 in after-hours trading as investors await the results.

It's shaping up to be an eventful Tuesday for earnings watchers, with plenty of volatility already showing up before the opening bell even rings.
