Management Commentary

• “bluebird is poised for accelerated growth throughout the rest of 2024” — Andrew Obenshain, CEO .
• “Today, we have 64 activated QTCs, unparalleled compared to others in the field.” — Thomas Klima, CCO/COO .
• “In the first quarter, we reported $18.6 million in total revenue, driven by revenue from ZYNTEGLO… we anticipate gross to net discounts in the range of 20% to 25%.” — Christopher Krawtschuk, CFO .
• “Published coverage policies are in place for more than 200 million U.S. lives [for LYFGENIA],” and “discussions [are] ongoing with Medicaid agencies representing 80%” of Medicaid-insured SCD individuals — Press release .
• “We anticipate recognizing revenue from [the] first infusion of LYFGENIA in the third quarter of 2024.” — Press release .

Q&A Highlights

• Medicaid access not a bottleneck: “It’s not a rate-limiting factor… patients can have access via medical exceptions until policies/OBAs are in place” .
• Patient-start definition and ramp: Starts are defined at first completed cell collection; management expects acceleration into 2H24 as centers and patients move through readiness steps .
• Capacity/readiness: 64 QTCs activated with ~50 receiving LYFGENIA referrals; early adopters moving to second/third patients; centers building gene therapy capacity .
• Manufacturing: Separate, more robust LYFGENIA supply chain; ability to scale capacity aligned to demand .
• Financial disclosure: Restatement limits near-term visibility on COGS/OpEx trends; timeline for filings not provided on the call .

Estimates Context

• S&P Global consensus data for Q1 2024 revenue and EPS were unavailable for BLUE at time of analysis; as a result, comparison to Street estimates could not be presented this quarter (S&P Global consensus unavailable).

Key Takeaways for Investors

• Commercial inflection: First LYFGENIA start and QTC/coverage footprint set the stage for initial LYFGENIA revenue in Q3 and a 2H24 ramp; watch quarterly patient starts and infusion conversions for trajectory confirmation .
• Network and access advantages: 64 QTCs activated and >200M covered lives, with Medicaid discussions spanning ~80% of insured SCD patients, should support broader adoption and reduce payer friction over time .
• Revenue momentum: Q1 revenue of $18.6M outpaced Q4 ($7.8M), driven by ZYNTEGLO; LYFGENIA contributions begin in Q3, providing a second growth leg .
• Temporary overhangs: Restatement delays cloud full financial transparency (EPS/margin), but management says cash/revenue unaffected; monitor filing timing and any updates on cost scaling to 70% long-term gross margin target mentioned previously .
• Capacity scaling: BLUE is proactively increasing supply components (adherent factor) and has distinct supply chains; execution on manufacturing and hospital throughput is key to meeting 85–105 start guidance .
• 2024 guide intact; runway extended: Patient-start range and GTN unchanged; runway extended to Q1 2026 (assumes loan tranche milestones), reducing near-term financing risk .
• Trading setup: Near-term catalysts include additional LYFGENIA starts, payer policy updates (Medicaid OBAs), and restatement/filing completion; the revenue mix shift to include LYFGENIA in Q3 is the pivotal fundamental catalyst .
