US Pre-Market SEC Filings Roundup — May 20, 2026
Overnight filings reveal a bifurcated market, with high-growth tech and LPG shipping surging while traditional energy, real estate, and cash-burning pre-revenue companies deteriorate sharply. Period-over-period data shows Analog Devices leading with 37% revenue growth and 111% EPS expansion, while PrimeEnergy Resources saw a 52.5% net income decline. Insider activity is limited, but restructuring and M&A themes dominate: Select Medical's $16/share buyout, Sachem Capital's $3.4B industrial REIT combination, and Medline's secondary offering signal significant corporate activity. Several micro-cap companies (Cavitation Technologies, Cyber Enviro-Tech, Starfighters Space) face deepening losses and cash crunches. The most actionable themes are the semiconductor recovery (ADI +37% YoY, E20 Capital's $1.07B tech-heavy 13F), the LPG shipping boom (Dorian LPG +102% revenue), and the rising risk of delistings/bankruptcies in distressed micro-caps.
