Werewolf Therapeutics, Inc. (HOWL)·Q1 2025 Earnings Summary
Executive Summary
- Q1 2025 was operationally strong: HOWL initiated dosing in the Phase 1b/2 WTX-330 trial, kept WTX-124 expansion arms actively enrolling, and reiterated plans to present interim WTX-124 data and meet the FDA in 2H 2025 .
- Financially, net loss was $18.09M and EPS was $(0.40); revenue was $0 as Jazz collaboration revenue has substantially completed—EPS beat consensus by ~$0.03 while revenue missed modestly versus a $0.30M estimate .
- Cash guidance improved: runway extended into 4Q 2026 (previously through at least 2Q 2026), reducing near-term financing risk amid upcoming data catalysts .
- New pipeline expansion: management introduced proprietary INDUCER T cell engagers with a first development candidate targeted by end of Q2 2025, broadening modality reach and potential future partnering options .
What Went Well and What Went Wrong
What Went Well
- WTX-330 progressed into Phase 1b/2 with first patient dosed, aiming to optimize exposure and build on encouraging first-in-human signals—speed of execution de-risks timelines .
- WTX-124 continued to show clinically meaningful anti-tumor activity with tolerable safety; expansion arms are actively enrolling at 18 mg IV Q2W, supporting a potential best-in-class IL-2 profile .
- Cash runway extended into 4Q 2026, increasing operational flexibility ahead of 2H 2025 regulatory interactions and interim data readouts .
Management quotes:
- “We remain on track... to share interim data and meet with the FDA to discuss potential registrational pathways in the second half of this year.” — Daniel J. Hicklin, Ph.D., President and CEO .
- “We recently initiated a Phase 1b/2 clinical trial of WTX-330 to explore antitumor activity and optimize the exposure... in the tumor microenvironment.” — Daniel J. Hicklin, Ph.D. .
- “Our proprietary PREDATOR masking and targeting technology distinctly positions us to build a robust pipeline of T cell engagers...” — Daniel J. Hicklin, Ph.D. .
What Went Wrong
- Revenue was $0 in Q1 2025 as Jazz collaboration revenue recognition ceased after performance obligations were substantially completed—driving reliance on cash and raising sensitivity to cost control .
- Net loss increased year over year (Q1 2025: $18.09M vs. $16.19M in Q1 2024) given continued R&D investment in clinical programs .
- No earnings call transcript available for Q1 2025, limiting visibility into real-time Q&A clarifications on regulatory strategy and trial enrollment pacing .

Values marked with * retrieved from S&P Global.
Notes:
- Collaboration revenue was zero in Q1 and Q4 2024 as performance obligations under the Jazz agreement were substantially completed in mid-2024 .
- With $92.0M cash at 3/31/25 and updated runway into 4Q 2026, liquidity appears sufficient for planned milestones .

Earnings Call Themes & Trends
No Q1 2025 earnings call transcript was available; themes derived from press releases and investor materials.
Management Commentary
- Strategic emphasis: advancing WTX-124 toward potential registrational discussions based on interim data in 2H 2025 while broadening the platform into INDUCER T cell engagers .
- Quote: “We remain on track... to share interim data and meet with the FDA to discuss potential registrational pathways in the second half of this year.” — Daniel J. Hicklin, Ph.D. .
- Quote: “We recently initiated a Phase 1b/2 clinical trial of WTX-330...” — Daniel J. Hicklin, Ph.D. .
- Platform positioning: “PREDATOR masking... positions us to build a robust pipeline of T cell engagers with potentially best-in-class potency and safety profiles...” — Daniel J. Hicklin, Ph.D. .
Q&A Highlights
- No Q1 2025 earnings call transcript was available in the document catalog; no Q&A highlights to report .
- Investor-facing materials (Exhibit 99.2 corporate deck) covered clinical design details, PK findings, and trial strategy, partially substituting for typical call clarifications .
Estimates Context
- EPS beat: Actual $(0.40) vs consensus $(0.4333), +$0.0333 surprise; indicates disciplined OpEx and absence of non-recurring charges in the quarter relative to expectations *.
- Revenue miss: Actual $0 vs consensus $0.30M; consistent with prior disclosure that Jazz collaboration revenue largely ceased after mid-2024 performance completion *.
- Forward consensus leans to continued negative EPS while revenue near zero given development-stage status (limited/no collaboration inflows) [GetEstimates forward periods]*.

Key Takeaways for Investors
- Near-term catalysts: interim WTX-124 data and FDA engagement in 2H 2025; WTX-330 regimen optimization in Phase 1b/2 with multiple expansion indications—key stock reaction drivers over the next 6–9 months .
- Liquidity improved: runway into 4Q 2026 reduces financing overhang through pivotal strategic inflections (data/FDA interactions) .
- Clinical validation narrative strengthening: durable responses across WTX-124 mono/combo and encouraging WTX-330 signals support platform differentiation; patient case reports reinforce mechanism and tolerability .
- Execution momentum: first patient dosed in WTX-330 Phase 1b/2 and active enrollment across WTX-124 arms at RDE (18 mg IV Q2W) demonstrate operational cadence .
- Pipeline breadth: INDUCER T cell engager candidate targeted by end Q2 2025 expands addressable opportunities and potential BD optionality .
- Estimate recalibration: consensus may adjust to slightly better EPS trajectory given cost controls; revenue remains negligible unless new BD/collaboration inflows emerge * *.
- Trading lens: Data timing and FDA dialogue represent primary narrative drivers; improved runway dampens near-term dilution risk and may increase sensitivity to positive clinical disclosures .
Additional Data and KPIs
