Stocks moved broadly in premarket trading as investors digested a string of corporate earnings reports and guidance updates across healthcare, technology, and consumer names. Among the biggest movers, Revvity rose after raising its full-year pro forma adjusted earnings per-share outlook, while Apple fell on a weaker-than-expected margin forecast and a miss on iPad sales. Other results—including Pfizer’s roughly flat trading, Palantir’s decline despite better-than-estimated earnings, and Zebra Technologies’ drop despite exceeding profit expectations—underscored how guidance and cash-flow signals are driving market reactions.
Key takeaways
- Revvity shares jumped about 7% after the life sciences company lifted its full-year pro forma adjusted EPS range, reinforcing investor focus on earnings durability.
- Apple shares fell nearly 4% in premarket on a disappointing margin forecast and iPad sales that missed Street expectations.
- Zebra Technologies dropped more than 6% even with a better-than-expected quarter, as investors weighed cash-flow and guidance nuances.
- Palantir slid nearly 8% despite topping estimates, highlighting that investors are still reacting to the mix of revenue strength and forward expectations.
- Gartner fell over 6% after earnings beat, suggesting that the market may have prioritized the company’s forward guidance or outlook details.
What drove the major premarket moves
Revvity was one of the clearest standouts. The company raised its full-year pro forma adjusted earnings per-share guidance to $5.40 to $5.45, up from a prior $5.30 to $5.40 range, supporting a sharp premarket gain. The update suggests management is pointing to stronger-than-previously expected earnings momentum for the year.
In contrast, Apple came under pressure after reporting results for its fiscal fourth quarter that included a margin forecast investors found disappointing. Apple also missed analysts’ expectations for iPad sales, contributing to premarket weakness of nearly 4%.
Pfizer traded near the flatline following its third-quarter report. The company reported third-quarter earnings of 87 cents per share, excluding certain items, on revenue of $16.58 billion. According to analysts polled by LSEG, the Street expected 73 cents per share on revenue of $15.87 billion—an outcome that may have limited downside reactions, even if investors were not moved enough to drive a substantial upside.
Zebra Technologies, which makes barcode scanners and mobile computers used in retail and other sectors, fell despite posting better-than-expected results. Zebra reported profit of $4.95 per share, excluding certain items, on revenue of $1.61 billion, compared with FactSet expectations for $4.89 per share on $1.57 billion. Still, shares declined more than 6% in premarket as investors weighed free cash flow guidance of at least $1 billion for the year, described as marginally below a $1.02 billion estimate.
Gartner also retreated, with shares sliding over 6% despite a third-quarter beat. The company delivered better-than-expected earnings and revenue, and issued better-than-expected full-year earnings and revenue guidance. The stock’s negative reaction indicates that investors may have focused on aspects of the outlook or the broader quality of the numbers not reflected in headline guidance levels.
Yum Brands, the parent of Taco Bell, was modestly higher after reporting a third-quarter beat. Adjusted earnings per share came in at $1.56, compared with LSEG’s forecast of $1.49, while revenue of $2.05 billion matched the Street consensus. The company also pointed to a rebound at Taco Bell following the cyclospora outbreak linked to iceberg lettuce, a factor that investors may view as improving near-term operating conditions.
Palantir, however, declined nearly 8% even after posting quarterly results that beat Wall Street estimates. The company reported that U.S. commercial revenue rose 148% to $984 million, exceeding U.S. government revenue of $953 million. Palantir also projected about $2.65 billion in fourth-quarter revenue and $8.53 billion for full-year 2026. Despite those positives, the premarket drop suggests investors were not fully satisfied with the outlook, margins, or other forward details—items that can outweigh headline revenue growth when positioning is cautious.
Market reaction: beats weren’t enough for several names
The premarket tape showed a common pattern: multiple companies beat earnings or revenue expectations, but shares still fell when guidance signals or specific line items failed to align with investor expectations. Zebra’s guidance for free cash flow—set at at least $1 billion—was cited as slightly below an estimate, illustrating how capital-return and cash metrics can drive valuation even when profits beat.
Similarly, Gartner’s decline despite better-than-expected results suggests that investors may have reacted to forward-looking details beyond headline earnings and revenue guidance. For Palantir, the split between strong U.S. commercial revenue and the company’s forward revenue projection did not translate into a positive share reaction, implying that the market may be scrutinizing the sustainability of growth rates or the composition of future business.
On the other hand, Revvity’s share jump showed that when guidance is raised—especially for full-year earnings—investors are willing to reprice expectations quickly. In Apple’s case, the margin forecast and iPad sales miss weighed more heavily, reinforcing that investors appear to be prioritizing profitability outlook and product demand signals in large-cap results.
What investors are likely watching next
Heading into the rest of the session, attention is likely to center on how management teams frame forward guidance—particularly for margins, cash flow, and segment performance. Companies with guidance raises may see continued support if investors interpret the update as strengthening earnings visibility. Names experiencing declines despite headline beats may face additional scrutiny from analysts on whether forward commentary points to cost pressures, weaker demand, or cash-flow normalization.
Investors should also watch for follow-on commentary on operational drivers referenced in these reports, including Taco Bell’s recovery trajectory after the cyclospora incident and the quality of Palantir’s commercial versus government revenue growth. With more earnings and corporate updates still in play, the market’s near-term direction may hinge on whether subsequent results and guidance deliver upside revisions or confirm areas of concern signaled by margin or cash-flow expectations.
