    Executive summary

    Biogen Q2 FY26 — Apellis Integration and Pipeline Catalysts Drive Growth Outlook

    Biogen is undergoing a significant transformation, with the successful integration of the Apellis acquisition and strong performance from its growth product portfolio driving a shift towards sustainable revenue growth. The company is also rebuilding its early-stage pipeline and advancing a robust late-stage pipeline, including multiple registrational readouts expected in the near term, positioning it for long-term value creation despite near-term integration and R&D investment costs.

    Highlights

    5
    • Growth product portfolio generated over $1 billion in revenue, up 24% year-over-year and 25% quarter-over-quarter, exceeding the legacy MS portfolio.

    • SPINRAZA high-dose conversion is progressing faster than expected, with anecdotal switchbacks from oral products, contributing to $402 million in revenue, up 2% year-over-year.

    • LEQEMBI IQLIK initiation received FDA approval, offering one-dosing for Alzheimer's treatment and potentially broadening patient eligibility.

    • Apellis acquisition (SYFOVRI and EMPAVELI) contributed $128 million in combined revenue post-acquisition (May 14), accelerating the return to growth.

    • Total second quarter core pharmaceutical revenue was $1.8 billion, up 4% year-over-year, demonstrating strong commercial execution.

    Concerns

    4
    • VUMERITY revenue was down 7% year-over-year to $197 million, partly driven by inventory dynamics.

    • Non-GAAP core operating expenses increased 20% year-over-year, reflecting approximately $95 million of Apellis operating expenses post-acquisition and R&D investments.

    • The Apellis transaction is expected to result in approximately $0.85 of non-GAAP diluted EPS dilution in FY26, primarily from financing costs.

    • Acquired IPR&D and milestone charges totaled $164 million in Q2 FY26, including a $100 million upfront for felzartamab rights in China.

    Risks & headwinds

    6
    Competitive market for SMA treatmentsLonger term

    Extremely competitive market

    Mitigation: SPINRAZA high dose offering considerable efficacy benefits, salinersen coming behind it to maintain market share.

    Competitive market for RRMS treatments

    Increasingly competitive nature of that market

    Mitigation: Evaluating next steps for BIIB091 (BTK inhibitor) despite compelling efficacy, prioritizing capital allocation.

    Biosimilar launch impact on TYSABRI

    TYSABRI revenue down 1% YoY

    Mitigation: TYSABRI demonstrating resilience in demand amidst biosimilar launch in the U.S. and Europe due to long-established importance for MS patients.

    High placebo responses in lupus trials

    High placebo responses seen in past trials

    Mitigation: Trial design for litefilimab (TOPAZ 1 and 2) includes rules to limit standard-of-care utilization and control patient heterogeneity.

    Patient drop-off due to IV administration for Alzheimer's treatments

    One of the largest drop-offs are patients not wanting to take IV in general

    Mitigation: LEQEMBI IQLIK (subcutaneous option) is expected to help accelerate the market by addressing this reason for patient drop-off.

    Dernunersen (Alzheimer's) is a high-risk, high-reward investmentLonger term (next decade)

    Not necessarily part of the equity story near term. Not something that's going to affect Biogen's growth over the rest of this decade.

    Mitigation: Signal is real, but still needs to go through Phase III. Company is doing a lot of investigation and discussion with the neurology community and consulting with the FDA.

    What to watch in Q3 FY26

    Lupus (SLE) Phase III Data Readouts

    Q4 2026
    CurrentTrials (TOPAZ 1 and 2) ongoing
    TargetResults from both trials

    Why it matters

    These readouts are key catalysts for Biogen's late-stage pipeline and could significantly impact the long-term growth outlook in the $8 billion lupus market.

    We are now entering a multiyear registrational cycle, beginning with SLE data by the end of this year.

    Q&A highlights

    6

    How is the high-dose SPINRAZA ramp progressing compared to expectations, what conversion metrics are being observed, and how significant are switchbacks from other therapies to overall volumes?

    High-dose SPINRAZA is exceeding the original launch in start forms and grads in its first 13 weeks, driven by patient demand and urgency. The majority of patients are transitioning from the lower dose, but new starts (including babies) and switchbacks from oral therapies are also occurring, particularly in ex-U.S. markets like Germany. The convenience of 2 loading doses versus 4 for the original SPINRAZA is also a factor.

    SPINRAZA high dose is exceeding the original launch of SPINRAZA in both start forms and grads in the first 13 weeks of launch, and we are growing every single week.

    Detailed Narrative

    01

    Strategic Transformation and Growth Drivers

    Biogen is actively pursuing sustainable revenue growth, driven by its expanding growth product portfolio, which now exceeds the legacy MS portfolio. The recent acquisition of Apellis, integrating SYFOVRI and EMPAVELI, is a significant contributor to this growth. The company is also focused on a robust late-stage pipeline with multiple near-term catalysts and a rebuilt early-stage pipeline, aiming to secure long-term innovation and value creation.

    02

    SPINRAZA High-Dose Success and Franchise Value

    The high-dose regimen of SPINRAZA has seen faster-than-expected conversion rates across all markets (Japan, Europe, U.S.), demonstrating significant efficacy benefits in a competitive market. This has led to anecdotal switchbacks from oral products and strong demand, with the high-dose regimen exceeding the original SPINRAZA launch in its first 13 weeks. This success reinforces the long-term value of the SPINRAZA franchise, supported by the upcoming salinersen.

    03

    LEQEMBI IQLIK Approval and Alzheimer's Market Evolution

    The FDA approval of LEQEMBI IQLIK initiation, the first one-dosing Alzheimer's treatment, is a major achievement. This subcutaneous option is expected to broaden patient eligibility by simplifying administration, potentially increase patient persistence on therapy, and offer a competitive advantage. While initial demand is being tracked, the company anticipates IQLIK will evolve the Alzheimer's market by addressing patient reluctance to IV infusions and improving workflow for physicians.

    04

    Apellis Acquisition Integration and Commercial Performance

    The integration of Apellis, which closed on May 14, is progressing well, with SYFOVRI and EMPAVELI showing strong performance. SYFOVRI generated $162 million in revenue, up 8% YoY, with commercial injections up 13% YoY, driven by reduced free drug programs and improved HCP sentiment. EMPAVELI revenue was $46 million, up 123% YoY. The acquisition is expected to materially contribute to top-line growth and non-GAAP diluted EPS accretion by 2027, with at least $250 million in run-rate synergies by the end of 2027.

    05

    Late-Stage Pipeline Catalysts and Accelerated Timelines

    Biogen is entering a multi-year registrational cycle with 5 Phase III readouts expected within the next four quarters across SLE, CLE, AMR, and Dravet syndrome. Notably, the Phase III readouts for felzartamab in AMR and mitipiimab in CLE have been accelerated to the first half of 2027. These opportunities represent significant potential for long-term growth, with lupus alone estimated as an $8 billion market and AMR as a $2 billion addressable market.

    06

    Rebuilding the Early-Stage Pipeline and Innovation Engine

    The company has made dramatic moves to overhaul its research organization, resulting in 3 IND filings this year and plans to add 6 new programs, including Phase II proof-of-concept studies and first-in-human studies. Strategic collaborations and acquisitions, such as the pending Vatera transaction, are boosting the early-stage pipeline, laying the groundwork for products launching in the mid-2030s and building a durable innovation engine.

    07

    Lupus (SLE/CLE) Market Opportunity

    Biogen sees a significant unmet need in lupus, particularly in CLE where less than 5% of patients receive advanced therapy. The company's SLE trials (TOPAZ 1 and 2) are designed to address high placebo responses and patient heterogeneity, focusing on patients with skin and joint involvement. The upcoming 52-week data for litefolumab in CLE at EADV is expected to provide important insights into durability, with management confident in the potential for a differentiated treatment.

    08

    Felzartamab's Potential in AMR and MVI

    Felzartamab in Antibody-Mediated Rejection (AMR) is viewed as a potential $2 billion addressable market, with Phase III data expected in H1 2027. The Phase II data showed an 80% resolution of AMR, and there is currently no approved product for this high unmet need. The company is also pursuing microvascular inflammation (MVI), a sizable population of 6,000 patients in the U.S., with a trial already underway, believing felzartamab's mechanism of action will be impactful in both indications.
