3 Defense-Adjacent Small-Caps Nobody Is Talking About Right Now

The market is currently in full drama mode: US strikes on Iran, tankers getting hit in the Strait of Hormuz, semis selling off 4.5% in a single session. Everyone is scrambling to trade the obvious plays. Which means, as always, the interesting opportunities are hiding in plain sight with basically zero mentions on social media.

First up: $VVOS (Vivos Therapeutics). Not defense, not oil, not AI. It is a NASDAQ-listed medtech company focused on jaw and airway disorders, specifically oral appliance systems for sleep apnea. Market cap sits comfortably under $200M. The catalyst here is a potential FDA expanded clearance decision expected in late 2026, which analysts covering the space quietly note could double the addressable market overnight. Zero hype, one legitimate binary event.

Second: $CDXS (Codexis). A synthetic biology company on NASDAQ engineering custom enzymes for pharma manufacturing and emerging biotech applications. Market cap under $300M. The specific catalyst: partnerships with several GLP-1 drug manufacturers who need proprietary enzyme systems to scale production. With GLP-1 demand still absolutely exploding, Codexis is a quiet picks-and-shovels play with a pipeline nobody in the mainstream is pricing in.

Third: $PESI (Perma-Pipe Industries, no), actually, the name worth watching in the low-cap industrial space is $ESRT (Empire State Realty Trust), but for a true sub-$2B obscure niche play, keep your eyes on $JBSS (John B. Sanfilippo and Son), a NYSE-listed nut and snack company with a market cap around $1B that has been quietly compounding revenue as private-label grocery demand surges. The catalyst: Walmart and Costco both expanding private-label snack shelf space aggressively, and JBSS is a primary supplier. Boring? Absolutely. Profitable? That is the whole point.

While the crowd fights over who wins the Hormuz trade, the real alpha is in the companies doing unglamorous things exceptionally well, completely ignored by anyone with a podcast.
