Key Points

  • Palantir beat Q2 estimates and raised full-year 2026 revenue guidance to $8.15–$8.158 billion, outperforming the $7.72 billion Wall Street estimate; shares rose 10%.
  • Snap and Backblaze reported better-than-expected Q2 results and issued optimistic Q3 or full-year guidance, contributing to after-hours gains of 9.6% and 16%, respectively; Snap signaled stabilizing ad demand while Backblaze cited enterprise migration to non-hyperscaler cloud solutions.
  • Ichor, GeneDx and Whirlpool fell after hours despite some positive elements in their reports - Ichor faced profit-taking after a run-up, GeneDx issued light Q3 revenue guidance, and Whirlpool missed Q2 results amid housing and consumer spending pressure.

Equity moves after the market closed reflected a split between companies reporting better-than-expected quarterly results with bullish outlooks, and companies that disappointed on results or forward guidance.

Palantir Technologies (PLTR)

Shares of Palantir jumped 10% after the company reported a second-quarter earnings per share of $0.41, topping consensus by $0.07, on revenue of $1.94 billion. Management highlighted demand for its Artificial Intelligence Platform (AIP) and raised the company’s full-year 2026 revenue guidance to a range of $8.15–$8.158 billion, which sits comfortably above the $7.72 billion Wall Street estimate. The company also provided strong guidance for the third quarter.

Snap Inc. (SNAP)

Snap climbed 9.6% following a better-than-expected top-line showing in Q2. The firm posted EPS of ($0.10), beating the ($0.12) loss consensus, on revenue of $1.6 billion. Management issued third-quarter revenue guidance of $1.7–$1.74 billion, a signal that advertising demand may be stabilizing while its Snapchat+ subscription service continues to gain traction.

Backblaze (BLZE)

Backblaze surged 16% after beating Q2 expectations, delivering EPS of $0.08 on revenue of $42.71 million. The cloud storage specialist issued a "beat-and-raise" outlook, increasing its full-year 2026 revenue target to $172–$174 million, ahead of the $162.3 million consensus, and attributing momentum to enterprise migrations toward non-hyperscaler cloud solutions.

ON Semiconductor (ON)

ON Semiconductor rose 5% after reporting Q2 EPS of $0.74 on $1.6 billion in revenue, topping expectations. The chipmaker set upbeat third-quarter targets, projecting EPS of $0.81–$0.93 and revenue up to $1.75 billion, commentary that reassured investors concerned about industrial and automotive power management demand bottoming out.

Ichor Holdings (ICHR)

In contrast, Ichor shares fell 11% despite a second-quarter beat—EPS of $0.34 on revenue of $294.78 million—and guidance for the third quarter that matched or exceeded analysts’ expectations. The pullback appeared driven by profit-taking after a recent multi-month run-up in semiconductor equipment suppliers, with traders evidently looking for a larger upside surprise in guidance.

GeneDx Holdings (WGS)

GeneDx declined 7% after reporting a wider-than-expected Q2 loss of ($0.28) per share, even as revenue of $114.4 million beat consensus targets. Investor concern was amplified by light third-quarter revenue guidance of $122–$124 million, which sits below the $126 million estimate, overshadowing the company’s reiterated full-year sales outlook.

Whirlpool Corporation (WHR)

Whirlpool shares dipped 4% after missing second-quarter top- and bottom-line estimates, reporting a loss of ($0.21) per share on $3.52 billion in revenue. Management provided a full-year EPS guidance range of $2.50–$3.00 that was slightly above analysts’ consensus, but the company noted ongoing pressure from soft housing market turnover and persistent consumer discretionary spending headwinds affecting home appliance demand.


Market context

The after-hours session highlighted how earnings beats and raised guidance can quickly lift technology and cloud names, while profit-taking and softer-than-expected near-term revenue targets can weigh on semiconductor equipment, diagnostics and consumer discretionary stocks. Movements were driven by reported results, forward guidance and investor positioning following recent runs in specific sectors.

Risks

  • Profit-taking in semiconductor equipment suppliers - Ichor’s share decline illustrates how rapid prior gains can lead to pronounced sell-offs when investors seek larger forward surprises.
  • Soft near-term revenue guidance in diagnostics and healthcare services - GeneDx’s lighter-than-expected Q3 revenue outlook could signal near-term demand sensitivity in genetic testing and related services.
  • Consumer discretionary and housing market weakness - Whirlpool’s miss and management commentary point to ongoing headwinds for home appliance demand tied to housing turnover and consumer spending trends.
