What believers are saying

  • Q2 2026 revenue rose 10% to $7.8 billion, led by HIV and Trodelvy.
  • Yeztugo PrEP sales surpassed $1 billion in Q2 2026, proving durable prevention demand.
  • California Supreme Court dismissed 23,000 HIV claims on August 3, removing litigation overhang.

What critics are saying

  • Biktarvy concentration exposes Gilead if ViiV or generics erode HIV share before 2036.
  • Veklury sales plunged 81% in Q2 2026, exposing dependence on shrinking pandemic revenue.
  • Anito-cel’s December 23, 2026 PDUFA is binary; rejection would weaken Gilead’s oncology expansion.

What makes Gilead Sciences unique

  • Biktarvy remains protected until April 1, 2036, anchoring Gilead’s HIV cash engine.
  • Gilead leads long-acting HIV prevention with Yeztugo, now available in 10 priority countries.
  • Its oncology mix combines Trodelvy, Yescarta, Tecartus, and anito-cel’s December 2026 launch.

Gilead Sciences down 11.3% in six months as revenue growth disappoints at 2.7% CAGR

Gilead Sciences' shares have fallen 11.3% to $137.77 over the past six months, contrasting with the S&P 500's 13.1% gain. The biopharmaceutical company has shown disappointing long-term performance, with revenue growing at just 2.7% annually over five years. The company's profitability metrics have deteriorated significantly. Its adjusted operating margin decreased by 34.2 percentage points over the past five years, landing at 9.7% for the trailing 12 months. Earnings per share declined by 15.4% annually during the same period, indicating reduced profitability as the company expanded. Despite trading at a relatively fair valuation of 14.9× forward price-to-earnings ratio, analysts suggest limited upside potential compared to downside risk.

Gilead Sciences beats Q2 estimates with $7.8B revenue as PrEP sales top $1B for first time

Gilead Sciences reported strong Q2 results, with revenue of $7.80 billion, beating analyst estimates of $7.35 billion. The 10.2% year-on-year growth was driven by its HIV franchise, particularly Biktarvy and the PrEP segment, alongside advances in oncology and liver disease treatments. CEO Daniel O'Day highlighted that quarterly PrEP sales doubled year-on-year, exceeding $1 billion for the first time. New product launches, including Trodelvy in breast cancer and Livdelzi in liver disease, contributed to the results. The company raised its full-year revenue guidance to $30.25 billion at the midpoint and increased adjusted EPS guidance by 44.1%. During the earnings call, analysts questioned management about prescription trends, product strategies, revenue diversification, regulatory interactions, and the impact of US insurance changes on Biktarvy's growth.

Nucleai advances ai-powered Tissue Intelligence through large-scale oncology ADC collaboration.

Nucleai advances ai-powered Tissue Intelligence through large-scale oncology ADC collaboration. Wednesday, August 12, 2026 Nucleai, a leader in AI-powered Tissue Intelligence, which integrates multimodal tissue image analysis with clinical data to deliver translational insights, today announced an ongoing translational research collaboration with Gilead Sciences supporting its global antibody-drug conjugate (ADC) clinical development programs. As oncology drug development increasingly depends on understanding tissue biology in its spatial context, AI-powered tissue analytics are becoming an essential component of biomarker discovery and translational research. Pharmaceutical companies are increasingly adopting approaches that integrate tissue architecture, biomarker expression, and clinical outcomes to accelerate therapeutic development. Nucleai's AI-native platform transforms routine pathology images into quantitative biological insights that accelerate biomarker discovery and support evidence-driven development decisions. As part of its collaboration with Gilead, Nucleai has analyzed a large dataset of hematoxylin and eosin (H&E) and immunohistochemistry (IHC) whole-slide images across several clinical studies spanning multiple oncology indications, supporting Gilead's global ADC clinical development programs through advanced AI-driven tissue analytics integrated with clinical outcomes. The collaboration has generated novel biological insights and candidate spatial biomarkers for future scientific presentations and publications. The collaboration demonstrates how AI-powered Tissue Intelligence can standardize biomarker analyses while connecting tissue biology to clinical outcomes, creating a scalable foundation for translational research, biomarker development, and precision medicine. "Precision oncology is entering a new phase, where understanding tissue architecture is becoming just as important as understanding molecular alterations," said Avi Veidman, Chief Executive Officer of Nucleai. "Tissue Intelligence is becoming a foundational capability for precision medicine, helping identify the patients most likely to benefit while enabling pharmaceutical companies to translate tissue biology into reproducible biomarkers that improve the speed and success of oncology drug development." Unlike traditional image analysis approaches, Nucleai's AI-native platform integrates computational pathology, spatial biology, clinical outcomes, and multimodal data into a unified framework. This enables standardized biomarker assessment from preclinical research through late-stage clinical development while revealing mechanisms of response, resistance, and disease progression. The ongoing collaboration with Gilead and other leading pharmaceutical companies reflects growing industry recognition that AI-powered tissue analytics strengthen biomarker development and precision medicine across oncology portfolios. As target expression alone proves insufficient to explain ADC response, Nucleai's Tissue Intelligence platform integrates protein expression with tissue architecture, tumor heterogeneity, and microenvironmental context to better characterize the biological drivers of therapeutic efficacy. "Scale and reproducibility are becoming essential requirements for biomarker development," said Dr. Ken Bloom, Head of Pathology, Nucleai. "Our platform enables standardized spatial analyses across thousands of clinical samples while directly linking tissue biology to patient outcomes, generating evidence that can support translational research, biomarker qualification, and future companion diagnostic strategies." Nucleai continues to expand collaborations with leading pharmaceutical companies to advance biomarker discovery, translational medicine, companion diagnostic development, and AI-powered Tissue Intelligence across the oncology development lifecycle. About Nucleai Nucleai is a leader in AI-powered Tissue Intelligence, transforming pathology images into clinically actionable insights for pharmaceutical companies developing the next generation of precision medicines. By integrating computational pathology, spatial biology, multi-omics, and clinical data, Nucleai enables biomarker discovery, translational research, companion diagnostic development, and enterprise-scale AI-powered tissue analytics across the oncology development lifecycle.

Gilead Q2 sales rise 8% to $7.8B, beating estimates despite acquisition-related loss

Gilead Sciences reported second-quarter product sales rose 8%, driven by double-digit growth in HIV drugs. Overall revenue increased 10% to $7.8 billion, surpassing Wall Street's $7.4 billion estimate. HIV sales grew 12%, whilst cancer drug Trodelvy and liver disease drug Livdelzi also performed strongly. HIV prevention drug Yeztugo generated $232 million, exceeding forecasts, whilst Descovy sales jumped 48% to $967 million. The company posted a quarterly loss due to acquisition costs. Gilead narrowed its projected full-year loss and slightly raised its revenue outlook to between $30.1 billion and $30.4 billion. The California-based biotech firm expressed confidence in achieving $1 billion in annual Yeztugo sales.
