Immuneering Corp (IMRX)·Q1 2025 Earnings Summary

Executive Summary

• Q1 2025 delivered a narrower net loss and EPS beat versus Wall Street: net loss was $15.0M and diluted EPS was -$0.42, beating S&P Global consensus of -$0.53 by ~$0.11; revenue remained zero given the pre-commercial stage . Values retrieved from S&P Global.*
• Operating discipline continued: R&D $11.5M (up modestly YoY) and G&A $4.0M (down YoY), with cash and equivalents of $35.9M and runway extended into 2026 .
• Clinical updates reinforced the IMM-1-104 thesis: first-line pancreatic cancer combination data (mGnP, mFFX) and second-line monotherapy results showed ORR/DCR improvements vs historical chemo benchmarks and notable PR/CR cases; PFS data in a larger cohort expected in Q2’25 .
• Near-term catalysts: initial progression-free survival readout in Q2’25 and additional combination arms; longer-term, Phase 3 initiation in first-line pancreatic cancer targeted for 2026—key stock narrative drivers .

What Went Well and What Went Wrong

What Went Well

• IMM-1-104 efficacy signals across settings: confirmed complete response in first-line combo therapy, confirmed partial response in second-line monotherapy, and durable disease control in third-line monotherapy (>13 months PFS case) .
• First-line pancreatic cancer combo arms showed favorable ORR/DCR vs historical benchmarks (mGnP ORR 43%, DCR 86%; mFFX initial ORR 50%), supporting potential Phase 3 path; tolerability remained differentiated and favorable .
• Corporate execution strengthened platform: Regeneron clinical supply agreement for Libtayo combo in NSCLC, addition of an experienced CMO to lead clinical development, and cash runway extended into 2026 .

What Went Wrong

• Still pre-revenue; net losses remain substantial with Q1 net loss at $15.0M despite sequential improvement from Q4, reflecting ongoing clinical spend .
• Interest income declined YoY ($0.44M vs $0.80M), reducing an offset to operating losses amid lower marketable securities/cash balances versus earlier periods .
• No earnings call transcript available in the system for Q1 2025; limited visibility into real-time management Q&A clarifications around study design nuances, regulatory dialogue, and timelines beyond prepared remarks [ListDocuments: earnings-call-transcript returned 0 for 2025-03-01 to 2025-06-30].

Financial Results

Estimate comparison:

Values retrieved from S&P Global.*

Observations:

• EPS beat driven by lower total operating expenses versus Q4 and steady G&A, partially offset by lower YoY interest income; sequential net loss improved from Q4 to Q1 .
• Cash decline versus Q3 reflects ongoing clinical progress and spend; management reiterated runway into 2026 .

No reportable segments; core activity remains R&D. KPIs (clinical) are shown below.

Clinical KPIs

Notes: Historical benchmarks for gemcitabine/nab-paclitaxel alone in 1L PDAC include ORR ~23% and DCR ~48% (MPACT); modified regimen ORR ~18.6%—suggesting improvement with IMM-1-104 combinations .

Guidance Changes

No revenue, margin, tax rate, OI&E or dividend guidance provided.

Earnings Call Themes & Trends

No Q1 2025 earnings call transcript available in the system. Themes are synthesized from Q3/Q4 press releases and Q1 8-K press release.

Management Commentary

• “In Q1, we showed that IMM-1-104 can drive exceptional efficacy for patients with pancreatic cancer, including a third-line monotherapy patient with over 13 months progression-free survival, a second-line monotherapy patient with a confirmed partial response, and a first-line combination therapy patient with a confirmed complete response... We are excited to share survival data in a larger group of patients in the coming weeks.” — Ben Zeskind, Ph.D., CEO .
• “Our corporate progress in Q1 has matched the pace of our clinical progress. We announced a clinical supply agreement with Regeneron, expanded our cash runway into 2026, and hired an outstanding Chief Medical Officer as we plan for the initiation of a Phase 3 trial in first-line pancreatic cancer patients.” — Ben Zeskind, Ph.D., CEO .
• On tolerability and efficacy: “We continue to observe a highly differentiated safety profile for IMM-1-104... setting a path to break new ground in indications where no MEK inhibitors have been approved, including pancreatic cancer.” — Ben Zeskind, Ph.D., CEO (Jan 7 update) .

Q&A Highlights

• No Q1 2025 earnings call transcript was available in the system; therefore, analyst Q&A themes, clarifications on regulatory interactions, and detailed dosing/arm expansion timelines could not be extracted [ListDocuments returned 0 for earnings-call-transcript].

Estimates Context

• EPS: Actual -$0.42 beat S&P Global consensus of -$0.53; 3 covering estimates. The beat appears driven by lower total operating expenses versus Q4 and steady G&A, with some contribution from interest income despite YoY decline . Values retrieved from S&P Global.*
• Revenue: Consensus was $0; actual remained $0 given pre-commercial status; 2 covering estimates. Values retrieved from S&P Global.*
• Implications: Estimates likely need modest upward revision for FY/quarterly EPS loss trajectory given sequential expense moderation and potential interest income; revenue remains anchored at zero until commercialization milestones are achieved . Values retrieved from S&P Global.*

Key Takeaways for Investors

• EPS beat vs consensus and sequentially improved loss profile signals operating discipline into major clinical catalysts in Q2’25 . Values retrieved from S&P Global.*
• Clinical momentum: favorable ORR/DCR in first-line combos and confirmed CR/PRs plus durable monotherapy case underpin the IMM-1-104 efficacy narrative ahead of PFS readout .
• Tolerability remains a differentiator for combination strategies, potentially enabling broader use with chemo, PD-1 inhibitors, and targeted agents across multiple indications .
• Strategic expansion: Regeneron Libtayo supply agreement extends combo footprint into NSCLC, adding optionality beyond PDAC .
• Cash runway into 2026 provides funding visibility through Phase 3 initiation planning; financing overhang appears limited near-term given stated runway .
• Near-term trading setup: Q2’25 PFS dataset is a binary-ish catalyst likely to drive estimate revisions and narrative change; positive survival signals could be a stock reaction driver .
• Medium-term thesis: If Phase 3 proceeds in 2026 with sustained efficacy/tolerability, IMM-1-104 may redefine MEK combination utility in PDAC, with optionality in melanoma and NSCLC through checkpoints/BRAF/G12C combinations .
