A cluster of corporate announcements during and after the bell triggered notable after-hours swings. Missed numbers and conservative guidance pressured Hims & Hers, while Archer Aviation advanced a regulatory milestone for eVTOL aircraft alongside quarterly results. Harmonic, AbCellera and Plug Power reported stronger-than-expected first-quarter metrics that lifted their shares, even as Power Solutions International and AST SpaceMobile posted disappointing results and Beazer Homes saw a dramatic takeover bid and board rejection that roiled its stock.

Key Points

  • Several companies reported first-quarter results after the bell, producing mixed reactions: HIMS missed estimates and guided 2026 revenue to $2.8–$3 billion, while HLIT, ABCL and PLUG beat expectations.
  • Archer Aviation reached Phase 3 of the FAA's Type Certification process for eVTOL aircraft, a regulatory milestone that accompanied its first quarter 2026 results and supported a share rise.
  • Beazer Homes experienced extreme intraday volatility after a $704 million unsolicited bid from Dream Finders Homes and a subsequent rejection by Beazer's board, leading to a late-session pullback.

Overview

After the market closed, a string of earnings releases and regulatory updates produced varied price action across several small- and mid-cap names. Some stocks moved higher after topping estimates or announcing milestones, while others fell following profit and revenue misses or corporate drama surrounding a takeover proposal.


Hims & Hers Health, Inc. (HIMS)

Hims & Hers shares slipped 7% in after-hours trading after the company reported first-quarter results that failed to meet analyst expectations. The firm posted Q1 EPS of ($0.40) and revenue of $608 million, both misses versus consensus. Despite the quarterly shortfall, management issued full-year 2026 revenue guidance in a range of $2.8 billion to $3 billion.


Archer Aviation Inc. (ACHR)

Archer shares rose about 4% after the company said it is the first to complete Phase 3 of the Federal Aviation Administration's Type Certification process for eVTOL aircraft. The regulatory milestone was announced together with the company’s first quarter 2026 financial results.


Harmonic (HLIT)

Harmonic shares climbed roughly 8% following a material beat on both the top and bottom lines for the first quarter. The company reported an EPS of $0.17 on revenue of $171.8 million, well above the consensus revenue estimate of $102.21 million.


AbCellera Biologics Inc. (ABCL)

AbCellera shares rose 6% after reporting a narrower-than-expected Q1 loss of ($0.15) per share and revenue of $8.31 million, which topped analyst estimates. The company also disclosed positive Phase 1 clinical trial data for its menopause treatment candidate ABCL635, noting a favorable safety profile in that early-stage study.


Plug Power (PLUG)

Plug Power climbed 5.7% after producing first-quarter results that beat Wall Street expectations. The company posted Q1 EPS of ($0.08) and revenue of $163.5 million, outpacing the consensus estimates of ($0.10) for EPS and $147.97 million for revenue.


Beazer Homes USA, Inc. (BZH)

Beazer Homes was the subject of abrupt intraday volatility tied to an unsolicited takeover approach. Shares earlier spiked by as much as 34% on a reported $704 million bid from Dream Finders Homes. In extended trading the stock fell 6% after the Beazer Board of Directors formally rejected the proposal, saying the offer significantly undervalued the company.


AST SpaceMobile, Inc. (ASTS)

AST SpaceMobile shares declined about 5% after the company released first-quarter results that missed estimates. The company reported a Q1 EPS of ($0.66), described as $0.45 wider than the anticipated analyst loss, and revenue of $14.73 million, well under the consensus estimate of $37.48 million.


Power Solutions International (PSIX)

Power Solutions International plunged roughly 35% following a disappointing second-quarter report. The company posted EPS of $0.36 and revenue of $128.6 million, with both figures falling significantly short of analyst targets.


Market takeaway

The after-hours session reflects a mixed set of catalysts: regulatory progress for an eVTOL maker, better-than-expected quarterly performance for several technology and energy names, clinical trial news in biotech, and takeover speculation in the homebuilder sector. Reactions varied from modest gains to large declines depending on how each company’s results or corporate developments stacked up against market expectations.

Risks

  • Earnings disappointment risk - Companies such as Hims & Hers, AST SpaceMobile and Power Solutions International reported results that missed expectations, which pressured their share prices and highlights sensitivity to quarterly performance - impacts the healthcare, aerospace and industrial sectors.
  • Regulatory and certification risk - Archer Aviation's progress through the FAA Type Certification process is a milestone but remains a key regulatory dependency for its aircraft program - impacts the aviation and eVTOL sector.
  • Mergers and takeover uncertainty - Beazer Homes saw a substantial unsolicited bid followed by a board rejection, creating short-term volatility and uncertainty around corporate control and valuation - impacts the housing and homebuilder sector.
