Executive Summary

Q3 2025 reported collaboration revenue of $1.594M and net loss of $5.520M, with basic/diluted net loss per share of $0.82; results were aided by a one-time $25.5M gain on lease termination recorded in August .
R&D and G&A both stepped up materially Q/Q (R&D $21.6M vs $15.5M; G&A $12.2M vs $7.7M) as restructuring and strategic alternatives progressed; excluding the lease gain, operating spending intensity rose Q/Q .
S&P Global consensus for Q3: revenue $0.55M vs actual $1.59M (beat); Primary EPS consensus -$3.18 vs S&P’s tracked Primary EPS actual -$4.60 (miss). Company-reported net loss per share was -$0.82; note definitional differences with S&P Primary EPS* .
Strategic alternatives remain the core narrative; the company updated cash, cash equivalents and marketable securities to $89.6M at quarter-end and reiterated expectation to fund operating expenditures “for the foreseeable future” .
Catalysts: any outcome of the strategic alternatives process, clarity on operating model post 90% workforce reduction (initiated in mid-August through end-October) and follow-on details around lease settlement accounting impacts .

What Went Well and What Went Wrong

What Went Well

Lease settlement delivered a $25.5M gain on lease termination, materially improving the Q3 loss from operations and net loss versus prior periods .
Collaboration revenue of $1.594M exceeded S&P Global consensus of $0.55M*, supporting top-line relative expectations in a biopharma development stage quarter .
Management reiterated confidence in ctLNP platform advances; prior quarter data highlighted “first-ever siRNA delivery to T cells in non-human primates,” validating selective delivery and tolerability in NHPs: “We believe this new NHP dataset is the first demonstration of siRNA delivery to T cells” .

What Went Wrong

Operating intensity increased Q/Q: R&D rose to $21.6M (from $15.5M) and G&A to $12.2M (from $7.7M), implying higher underlying cash burn excluding lease accounting impacts .
Primary EPS (S&P definition) missed consensus (-$4.60 vs -$3.18*), indicating a wider per-share loss under S&P’s methodology despite company-reported net loss per share of -$0.82 .
Strategic restructuring included a ~90% workforce reduction through October, underscoring significant organizational contraction as alternatives are evaluated, which may raise continuity and execution questions near term .

Estimates Context

Metric	Consensus (S&P Global)	Actual	Beat/Miss
Revenue ($USD)	$0.55M*	$1.594M	Bold beat vs consensus*
Primary EPS ($)	-$3.175*	-$4.604*	Bold miss vs consensus*

Footnote: Company-reported basic/diluted net loss per share for Q3 2025 was -$0.82 , which differs from S&P’s “Primary EPS” definition.
*Values retrieved from S&P Global.

Implications:

Revenue outperformed consensus, while EPS comparison depends on EPS definition. For trading and model purposes, align on EPS definition (company vs S&P Primary EPS) before concluding on magnitude of the beat/miss .

Key Takeaways for Investors

The $25.5M lease termination gain materially improved Q3 headline loss metrics; normalize for this one-time item when assessing operating trajectory .
Underlying OpEx rose Q/Q, with R&D and G&A increasing; watch post-restructuring OpEx trend in Q4 as 90% workforce reduction fully flows through .
Strategic alternatives are the dominant narrative; updates (advisor-led process, transaction outcomes) are key stock catalysts near term .
Liquidity stepped down to $89.6M at Q3; management expects funding of operating expenditures for the foreseeable future — monitor cash burn and runway disclosures for durability .
Collaboration revenue beat consensus; however, variability and limited scale suggest focusing valuation on platform optionality and potential strategic outcomes rather than near-term revenue .
EPS comparisons are definition-sensitive; reconcile S&P “Primary EPS” vs company-reported net loss per share in models to avoid misinterpretation of headline beats/misses* .
Absent a Q3 call transcript, sentiment cues will likely come from filings and press releases; remain attentive to any 8-Ks related to strategic alternatives or restructuring completion .
