Gilead’s Re-Rating: A Shift Toward Durable Growth and Margin Visibility
Share

Over the past 6–9 months, Gilead Sciences has undergone a quiet but powerful re-rating. Once viewed as a defensive value stock with limited growth, the company is now increasingly seen as a high-quality biotech franchise with visible margin expansion, commercial durability, and late-stage pipeline catalysts.

Total return since mid-October 2024 is +32%, far ahead of biotech benchmarks and in line with strong upward revisions in consensus margin forecasts.

The shift is visible across blended forward (BF) valuation metrics: Gilead now trades at a 2% premium on EV/EBITDA and near parity on EV/EBIT, erasing a multi-year discount. Its BF P/E has risen to 13.6x - ~2 standard deviations above historical norm - underscoring improved sentiment around earnings quality and capital efficiency.

Multiple high-margin growth drivers are coming into focus: lenacapavir for HIV prevention (approved June 2025), renewed HIV revenue growth in 2026, and potential 2026 launches for anito-cel and expanded Trodelvy labels. At the same time, operating discipline has returned Gilead to margin leadership in large-cap biotech.

With long-term estimates now stabilizing and stock momentum pausing, investors may be waiting for the next leg. Execution on 2026 catalysts will determine whether this is a new baseline, or just the setup for another step higher.

Risks to Watch

  • Medicare headwinds: Part D reforms will weigh on HIV revenue in 2025 (~$900M impact).

  • Pipeline dependency: Execution risk remains for key launches (lenacapavir, anito-cel, Trodelvy).

  • ADC competition: Trodelvy faces increasing pressure in breast and lung cancer.

  • Regulatory uncertainty: Shifting FDA timelines, global access issues may affect launch cadence.

  • Valuation compression: With multiples near historical peaks, any growth stumble could trigger derating.
