Willdan $WLDN Up 14% and Sezzle $SZLE Up 51% Revenue: Two Hidden Gems

Everyone is busy staring at Palantir's 40% surge and The Trade Desk's 21% crater. Fair enough. But while you were distracted, two genuinely obscure small-caps quietly posted some of the cleanest earnings in the entire reporting season, and almost nobody noticed.

First up: $WLDN (Willdan Group). If you've never heard of them, you're in good company. Willdan provides engineering and energy efficiency services to utilities and municipalities across the U.S., basically the unsexy backbone of grid modernization. The stock jumped over 14% in a single session after the company beat earnings expectations by a jaw-dropping $0.85 per share. Management followed the beat by laying out aggressive fiscal year 2026 targets, including net revenues up to $430 million. The reason this name stays under the radar: it operates in a niche infrastructure consulting space with no consumer-facing product and zero hype cycle. The catalyst to watch is continued government infrastructure spending and utility capex, both of which are accelerating as the energy security conversation intensifies. Seeking Alpha's quant rating calls it a Hold on valuation post-pop, which feels like analysts covering their eyes after missing a 14% day.

Second pick: $SZLE (Sezzle). This is a buy-now-pay-later fintech that has somehow avoided becoming the next Klarna punching bag. Sezzle just reported a blockbuster Q2 with revenue up 51.7% to nearly $150 million and transaction volume surging 37.9%. The company raised full-year guidance after the print. The really interesting detail is buried in the operational data: AI is now deflecting 68% of customer support inquiries, which is an insane efficiency number that directly compresses the cost structure. Seeking Alpha's quant model rates it a Strong Buy, citing sector-leading profitability and efficient scaling. The bear case is real, BNPL has a brutal track record and credit quality can deteriorate fast in a weakening jobs market. With U.S. payrolls down 23,000 in July, that's a risk worth pricing in.

Both companies share the same profile: mid-cap obscurity, no Wall Street cheerleaders, and genuine operational momentum that doesn't depend on AI hype or macro tailwinds doing them any favors. That combination is pretty rare right now.

The best hidden gems are the ones where the chart moves before anyone on CNBC learns how to pronounce the company name.
