Pharmaceutical Preparations · SIC 2834 · Vertical: Pharmaceutical Preparations (SIC 2834)

47.51USD−0.46% · 1 dayClose 04 Nov 2026

AnaptysBio now exclusively manages the financial collaborations for Jemperli with GSK and imsidolimab with Vanda, after spinning off its clinical biopharma business, First Tracks Biotherapeutics, on April 20, 2026. Revenue comes from royalties, and the net loss in the first quarter of 2026 shows the cost structure is still adjusting. The key question is whether royalties grow enough to sustain the company and return value to shareholders.

At the close of 04 Nov 2026, AnaptysBio, Inc. (ANAB) stock was 47.51 USD (−0.46% on the day), with market capitalisation 1.4 bn USD, P/E 11.5 on diluted EPS of 4.14 USD over the last 12 months, beta 0.81, 52-week range 22.06–69.81 USD. Latest reported quarter (Q2 2026): revenue of 27.5 m USD (+23.5% YoY), net income of 183.9 m USD, diluted EPS 3.98 USD.

Memo

ANAPTYSBIO, INC. (ANAB). Latest full fiscal year: 2025; data up to 2026-06-30.

Figures computed from the financial statements: revenue 234.6 m USD in 2025; YoY growth 157.0%; net margin 82.4%.

The estimated value range is 61.85–180.58 USD per share (median of 1 methods, agreement: single method); assumptions are illustrative. Against the central value of 120.61 USD, the price of 47.51 USD leaves a potential of 153.9% (value / price − 1) and a margin of safety of 60.6% (1 − price / value). The range is the median of the methods' low, central and high values, not a probability interval.

Insufficient data for a verdict (score weight coverage: 50.0% of at least 60%).

Text generated deterministically from the figures shown; no language model. Not investment advice.

What supports the thesis

  • Net margin: 82.4%
  • Revenue CAGR 3Y: 183.6%
  • Current ratio: 5.6x
  • P/E (TTM): 11.5x
  • The price is below the estimated value range

What contradicts it

  • FCF conversion: 9.2%
  • FCF yield: 1.3%
  • Shareholder yield (distributions): 0.9%

Not assessed (insufficient data or a ratio without meaning): ROIC, EPS CAGR 3Y, Net debt / EBITDA, Interest coverage, EV/EBITDA, Payout ratio (FCF).

In brief

AnaptysBio now exclusively manages the financial collaborations for Jemperli with GSK and imsidolimab with Vanda, after spinning off its clinical biopharma business, First Tracks Biotherapeutics, on April 20, 2026. Revenue comes from royalties, and the net loss in the first quarter of 2026 shows the cost structure is still adjusting. The key question is whether royalties grow enough to sustain the company and return value to shareholders.

SWOT

Strengths

  • Recurring royalty revenue tied to an approved product that is growing rapidly.
  • Lean operating structure with minimal costs, which could support high margins.
  • Cash and investment reserves that provide a buffer for current activity.

Weaknesses

  • Dependence on the performance of a single product controlled by an external partner.
  • Net losses in the first quarter of 2026, with rising general and administrative costs.
  • Stockholders' equity has fallen significantly, which limits financial flexibility.

Opportunities

  • New GSK trials for Jemperli could expand indications and royalty volume.
  • An FDA decision on imsidolimab could generate new milestones and royalties.
  • New board members with royalty experience could help manage the value of the assets.

Threats

  • A failed trial or delay in GSK programs could reduce royalty prospects.
  • The litigation with GSK could create extra costs and affect the collaboration.
  • If the separation does not create the expected value, returning value to shareholders could be weaker than estimated.

Risks

  • Dependence on Jemperlihigh

    Revenue depends mainly on royalties from Jemperli, which GSK controls. Any change in the partner's strategy or performance could directly affect revenue.

  • Litigation with GSKmedium

    Legal costs tied to the GSK litigation have increased general and administrative expenses. The outcome could influence the terms of the collaboration.

  • Effects of the separationmedium

    The split into two companies is complete, but reclassifying assets and liabilities may create accounting and operational uncertainty.

  • Royalty financing structuremedium

    Monetizing royalties through non-recourse financing involves debt payments that reduce the income available to shareholders.

  • Imsidolimab approvallow

    The application for imsidolimab is under FDA review, and a negative decision could reduce the prospects of this agreement.

Investment thesis

What would need to be true (bull case)

  • If Jemperli sales keep growing and royalties approach the levels announced, the company could have stable revenue with high operating margins.
  • The lean operating structure and the share buyback program could support returning value to shareholders.
  • New GSK trials and the imsidolimab decision could add unexpected revenue sources in the coming years.

What would break the thesis

  • If Jemperli sales slow or trials fail, royalty revenue could be lower than estimated.
  • Net losses and litigation costs could erode stockholders' equity, which is already reduced.
  • If the separation did not create enough value, the company could be left with limited revenue and royalty-related debt.

What to watch

  • Jemperli sales reported by GSK and royalties received by AnaptysBioQ2 2026
  • Completion of the reduction of debt tied to the royalty monetizationend of Q2 2027
  • FDA decision on imsidolimab in generalized pustular psoriasisDecember 12, 2026

Products, market & competition

The business

AnaptysBio, Inc. (Nasdaq: ANAB) was until recently a clinical-stage biotechnology company focused on immunology therapeutics for autoimmune and inflammatory diseases. In September 2025, its board approved plans to explore separating the business into two independent public companies. The separation was completed on April 20, 2026, and the clinical programs, including rosnilimab, ANB033 and ANB101, moved to First Tracks Biotherapeutics. AnaptysBio keeps management of the financial collaborations, meaning the royalties on Jemperli and imsidolimab. The company has not generated product sales; its revenue comes from license payments, research funding, milestones and royalties.

Trends

  • Growth of Jemperli salestailwind

    Jemperli sales are growing strongly, and GSK is investing in new trials, including in rectal and colorectal cancer. If these trials succeed, royalties could grow over the longer term.

  • Higher G&A from separation and litigationheadwind

    The company reported higher general and administrative expenses, partly due to legal costs of the separation and the GSK litigation 3. If these costs persist, they could reduce operating margins.

  • Imsidolimab approval processmixed

    Vanda submitted the application for imsidolimab in generalized pustular psoriasis, and the FDA has set a target action date. A favorable decision could trigger new milestones and royalties.

  • Share buyback and a leaner operating modelmixed

    The company announced a share repurchase program and a lean operating structure with few employees. This model could raise profitability, but it limits the ability to develop new programs.

Competitive position

AnaptysBio does not face direct product competition in the Jemperli market, since commercialization belongs to GSK. The relevant competition is for capital and partners in the royalty and immunology biotech space. The company also competes for the resources it needs for its new activities after the separation.

  • GSKGSK

    Company that markets Jemperli and controls development strategy and sales, from which AnaptysBio receives royalties.

  • Vanda PharmaceuticalsVNDA

    Partner that holds the global license for imsidolimab and is pursuing its approval in generalized pustular psoriasis.

  • First Tracks Biotherapeutics

    Company spun out of AnaptysBio that takes on the clinical work with rosnilimab, ANB033 and ANB101 and competes for capital and investor attention.

  • XOMA Royalty

    Company specialized in acquiring biotech royalties, referenced in the context of a board appointment.
