After the closing bell, a number of companies released results or corporate news that prompted notable after-hours price swings. The moves reflected a mix of earnings beats, guidance that slightly missed market forecasts, operational recalls, contract losses and equity issuance plans.
Zscaler (ZS) dropped sharply, falling 16% after hours. The security-software firm reported results that beat expectations for the third quarter and reiterated strong full-year guidance. The company also signaled full-year revenue of about $3.33 billion. However, investors focused on the fourth-quarter revenue outlook of $875 million to $878 million, which measured just below analysts' consensus of $879.1 million.
Digital Turbine (APPS) climbed 15% in extended trading after delivering a solid fourth-quarter earnings beat. The company reported adjusted earnings per share of $0.16 versus analyst estimates of $0.10. Management also issued fiscal 2027 revenue guidance in the range of $630 million to $650 million, well ahead of the market consensus of $619 million, supporting the post-close rally.
Semtech (SMTC) advanced 5% following quarterly results that surpassed expectations on both revenue and earnings. The chipmaker posted quarterly revenue of $291 million. Investors responded positively to forward-looking guidance for the second quarter of fiscal 2027, which included an EPS range of $0.59 to $0.63 and revenue that the company said sits well ahead of Wall Street's consensus.
Box (BOX) edged lower by about 3% after hours despite a narrow beat on first-quarter earnings and revenue. The decline came after management issued full-year fiscal 2027 EPS guidance of $1.56, slightly under the analyst consensus of $1.57.
Insulet (PODD) slipped 6% after announcing a voluntary Medical Device Correction affecting specific lots of its Omnipod 5, Omnipod DASH and Omnipod Eros systems. The company said internal monitoring identified a manufacturing issue that could potentially result in insulin under-delivery for some users, prompting the correction.
Verra Mobility (VRRM) plunged 29% in after-hours trading following disclosure that Avis Budget Group issued a major contract termination notice. The termination is scheduled to take effect in September 2026 and was interpreted by investors as a significant negative development for Verra Mobility's near-term outlook.
Firefly Aerospace (FLY) presented a mixed picture. The stock had jumped 18% during the regular session after revealing a $75 million subcontract award from NASA's Jet Propulsion Laboratory. However, Firefly reversed course after hours, falling 6% when it announced a public offering of 12 million shares of common stock to be sold by the company and certain selling stockholders.
The after-hours session illustrated how forward guidance and corporate actions can have an outsized effect on share prices even when quarterly results are in line with or better than expectations. Tech, semiconductor, healthcare device, mobility and aerospace names were among the most affected.
