Karyopharm Therapeutics Inc (NASDAQ:KPTI) Reports Q3 2025 Revenue Beat and Earnings Miss

Karyopharm Therapeutics Inc (NASDAQ:KPTI) reported financial results for the third quarter of 2025 that presented investors with a mixed picture, delivering a revenue beat while falling short on earnings expectations. The company's stock has shown notable pre-market activity following the release, suggesting traders are weighing these conflicting signals against the company's ongoing clinical developments.

Recent Performance

The market's immediate reaction to Karyopharm's earnings report appears cautiously optimistic despite the earnings miss. In pre-market trading, the stock has advanced approximately 3.45%, indicating some positive sentiment among investors. This early movement contrasts with the stock's recent trajectory, which has seen declines across multiple timeframes:

• Over the past month: -9.09%
• Over the past two weeks: -2.19%
• Over the past week: -8.52%

The pre-market gain suggests investors may be focusing more heavily on the revenue beat and pipeline updates rather than the earnings shortfall, though trading volume during this period is typically light.

Financial Results Versus Estimates

Karyopharm's third quarter performance presented a clear divergence between top-line and bottom-line results compared to analyst expectations. The company demonstrated stronger product revenue growth while continuing to face significant operational expenses.

• Revenue Performance:

  • Reported Revenue: $44.04 million
  • Analyst Estimate: $42.04 million
  • Beat by: $2.00 million (4.8%)

• Earnings Per Share:

  • Reported Non-GAAP EPS: -$3.82
  • Analyst Estimate: -$3.19
  • Miss by: -$0.63 per share

The revenue strength was primarily driven by the company's commercial product XPOVIO®, which generated $32.0 million in U.S. net product revenue, representing an 8.5% increase compared to the same quarter in 2024.

Pipeline and Business Updates

Beyond the financial figures, Karyopharm provided significant updates regarding its clinical development pipeline that may be influencing investor sentiment. The company confirmed that top-line data from its Phase 3 SENTRY trial in myelofibrosis remains on track for March 2026. This upcoming catalyst represents a potentially important value-driving event for the company, as success in this larger indication could substantially expand the commercial opportunity for selinexor beyond its current oncology applications.

Forward Outlook and Analyst Expectations

Looking ahead, analysts have established expectations for the company's fourth quarter and full-year 2025 performance that investors will use to gauge the company's progress:

• Q4 2025 Analyst Estimates:

  • Revenue: $40.97 million
  • EPS: -$2.01

• Full-Year 2025 Analyst Estimates:

  • Revenue: $152.31 million
  • EPS: -$11.30

The company did not provide formal financial guidance in the press release, leaving these analyst estimates as the primary benchmark against which future performance will be measured.

The market's reaction to Karyopharm's earnings reflects the complex calculus investors must perform when evaluating development-stage biopharmaceutical companies. While the earnings miss highlights the ongoing financial challenges of maintaining research-intensive operations, the revenue beat and maintained pipeline timelines appear to be receiving greater emphasis in early trading. The sustained growth of XPOVIO revenue provides near-term validation of the company's commercial capabilities, while the upcoming SENTRY data readout represents a meaningful medium-term catalyst that could redefine the company's growth trajectory.
