Today's After Hours Market Analysis

TODAY, 5:45p ET: Earnings and secondary offerings drive after-hours volatility amid mixed sector signals. URI surging +15.5% after reporting record revenue and raising full-year 2026 guidance; TXN +10.8% on strong results. ASGN plunging -25.2% following a significant Q1 earnings miss; MEDP -19.1% despite a beat as investors weigh backlog conversion. ALT -13.5% on a dilutive secondary offering.(more...)

Tape Overview

The after-hours session is defined by sharp, earnings-driven divergence and a risk-off reaction to secondary offerings, despite strength in heavy industrials and semiconductors.

Top Mover: United Rentals, Inc. (URI) — Record Q1 results and guidance hike

Shares surged +15.5% on 581k shares after the company reported record first-quarter rental revenue and raised its full-year 2026 outlook. Management cited sustained demand for large-scale infrastructure and data center projects as primary growth drivers.

Top Loser: ASGN Incorporated (ASGN) — Significant Q1 earnings miss

The stock plummeted -25.2% on 533k shares following a disappointing quarterly report where non-GAAP EPS of $0.69 missed estimates by $0.29. Revenue of $968.3 million also fell short of analyst expectations, triggering a sharp sell-off in the IT services provider.

Also Moving

Texas Instruments Incorporated (TXN) climbed +10.8% on 11.3m shares following its earnings release, while Altimmune, Inc. (ALT) dropped -13.5% after announcing a proposed public offering of common stock and warrants. Axe Compute Inc. (AGPU) retreated -15.0% on 83m shares, cooling off after a massive intraday rally fueled by a $260 million Nvidia GPU contract.

Broader Context

Traders should monitor the semiconductor space for follow-through momentum after TXN results, while keeping a close eye on high-volume "unusual" movers like Newsmax, Inc. (NMAX) for potential momentum shifts.
