Executive Summary

Q4 2024 GAAP net loss improved year over year to $49.1M ($0.21 per share) from $88.1M ($0.45 per share) in Q4 2023, reflecting lower operating expenses and favorable non-cash remeasurements of success payment liabilities and contingent consideration .
Non-GAAP net loss in Q4 2024 was $54.8M ($0.23 per share) vs. $69.1M ($0.35 per share) in Q4 2023; full-year 2024 non-GAAP operating cash burn fell to $195.1M from $233.0M in 2023 .
Cash, cash equivalents, and marketable securities were $152.5M at 12/31/2024; management reiterated expected cash runway into 2026, aided by 2024 equity financing proceeds of $181M .
Clinical momentum is a key 2025 catalyst: positive 12-week T1D (UP421) investigator study data without immunosuppression, plus expected 2025 readouts for SC291 (GLEAM) and SC262 (VIVID); INDs for SC451 (T1D) and SG299 (in vivo CAR-T) targeted as early as 2026 .

What Went Well and What Went Wrong

What Went Well

Expense discipline: R&D ($47.0M) and G&A ($17.3M) decreased year over year in Q4, driven by lower personnel/lab costs (portfolio prioritizations), reduced third-party manufacturing, and lower facility/allocated costs; partially offset by higher clinical development costs .
Improved non-GAAP profile: Q4 2024 non-GAAP net loss of $54.8M vs. $69.1M in Q4 2023; FY24 non-GAAP operating cash burn declined to $195.1M from $233.0M in FY23 .
Clinical validation narrative strengthened: “The updated preliminary 12-week clinical data for UP421 … increase our confidence that we can successfully transplant hypoimmune-modified pancreatic islets … without any immunosuppression,” said CEO Steve Harr; 2025 data expected for SC291 and SC262 .

What Went Wrong

Continuing heavy cash use: FY24 GAAP cash used in operations of $223.2M and capex of $33.4M (offset by $181.0M in equity financing), with year-end cash of $152.5M—runway into 2026 but dependent on continued execution and financing windows .
Non-cash valuation volatility persists: success payment liabilities and contingent consideration remeasurements materially affect GAAP results and are tied to stock price/market cap, introducing P&L variability .
No revenue and ongoing losses: Q4 loss from operations was $50.9M, reflecting the pre-commercial stage of the pipeline .

Management Commentary

“The updated preliminary 12-week clinical data for UP421 … increase our confidence that we can successfully transplant hypoimmune-modified pancreatic islets into a type 1 diabetes patient without any immunosuppression, a result we view as transformational for the company and the field… We expect to share clinical data later this year from two clinical-stage programs, SC291 and SC262… and expect to file an IND [for SC451 and SG299] as early as 2026.” — Steve Harr, President & CEO .
On UP421 results: the study demonstrated C‑peptide production and MMTT response, MRI signals consistent with graft survival, no safety issues, and immune evasion without immunosuppression; longer-term follow-up planned in publications/conferences .

Key Takeaways for Investors

Cash runway into 2026 with $152.5M on hand reduces near-term financing pressure; FY24 non-GAAP operating burn of $195.1M came in below the sub-$200M framework despite Q3 cautionary language .
Clinical catalysts are front and center for 2025: initial data from GLEAM (SC291) in B-cell autoimmune disease and VIVID (SC262) in B‑cell malignancies are expected this year; T1D program continues to build evidence with UP421 and aims for SC451 IND in 2026 .
Q4 operating profile improved YoY: lower R&D and G&A and narrower net loss vs. Q4 2023, aided by expense actions and valuation-driven non-cash gains (success payments/contingent consideration) .
Volatility in non-cash remeasurements (tied to market cap/stock price) will continue to impact GAAP loss; use non-GAAP trends for underlying spend trajectory (R&D and G&A declines YoY) .
Manufacturing and supply chain investments are strategic enablers for later-stage development; management cited progress alongside T1D momentum .
Near-term narrative is binary on clinical data flow; absence of revenue and ongoing losses mean stock action will be driven by readouts (UP421 updates, SC291/SC262 data) and capital planning. Pipeline timing (INDs in 2026) provides medium-term milestones .
