Previous Earnings Reports
| Date | Event | Sentiment | Move | Catalyst |
|---|---|---|---|---|
| Mar 19 | Earnings and update | Positive | +4.0% | Q4/FY 2025 results plus Breakthrough Therapy status and BLA timeline details. |
| Nov 05 | Earnings and update | Positive | -15.3% | Q3 2025 results and strong FXN biomarker and mFARS outcome data for nomlabofusp. |
| Aug 14 | Earnings and financing | Positive | +14.5% | Q2 2025 results, robust cash of $203.6M, and clear BLA/Phase 3 development path. |
| Apr 30 | Earnings and update | Positive | +10.9% | Q1 2025 financials with progress on FXN surrogate endpoint and Phase 3 planning. |
| Mar 24 | Earnings and outlook | Positive | -10.2% | FY 2024 results and roadmap toward BLA and global Phase 3 for nomlabofusp. |
Earnings and update releases have often been constructive but produced mixed reactions, with three positive and two negative one-day moves despite generally positive developmental progress.
Across the last five earnings-tagged updates from Mar 24, 2025 through Mar 19, 2026, Larimar consistently tied financial results to progress for nomlabofusp in Friedreich’s ataxia. Prior reports highlighted advancing toward a BLA, growing cash balances, and stronger regulatory positioning, including Breakthrough Therapy Designation and plans for accelerated approval. Price reactions have alternated between gains and drawdowns, underscoring that even clearly positive clinical and cash runway updates have not produced uniformly positive trading responses.
Historical Comparison
Over the last five earnings-style updates, LRMR’s average one-day move was about 0.77%, with both rallies and selloffs despite steadily advancing nomlabofusp toward a BLA.
Successive earnings updates have tracked Larimar’s evolution from early nomlabofusp development to Breakthrough Therapy designation, advancing open-label data, and a clearly defined accelerated-approval BLA and Phase 3 path.
Market Pulse Summary
The stock moved -5.1% in the session following this news. A negative reaction despite detailed guidance on BLA timing and cash runway would fit past episodes where solid development updates met selling pressure. Historical earnings releases have produced both gains and double-digit pullbacks, with an average move near 0.77%. Execution risks around the rolling BLA submission, the adequacy of the safety dataset, and Phase 3 outcomes could all contribute to cautious positioning.

BALA CYNWYD, Pa., May 14, 2026 (GLOBE NEWSWIRE) -- Larimar Therapeutics, Inc. (Larimar) (Nasdaq: LRMR), a clinical-stage biotechnology company focused on developing treatments for complex rare diseases, today reported its first quarter 2026 operating and financial results.
“We have strong momentum as we advance nomlabofusp towards potential approval for the treatment of adults and children with Friedreich’s ataxia (FA). Our ongoing engagement with the U.S. Food and Drug Administration (FDA) continues to support our registrational strategy. As we are coming down the homestretch for the submission of our BLA, pending FDA feedback, we are planning to seek accelerated approval and initiate a rolling BLA submission in June with the nonclinical and clinical modules. To facilitate a seamless review process, we continue to focus on the completeness of our chemistry, manufacturing, and controls (CMC) module, and plan to submit the CMC portion of the BLA in the second half of 2026,” said Carole Ben-Maimon, MD, President and Chief Executive Officer of Larimar Therapeutics. “We look forward to having a Type B meeting prior to initiating the rolling submission to obtain additional FDA feedback on the BLA content. We expect to report topline data from our open-label (OL) study this quarter and plan to dose the first patient in our global confirmatory Phase 3 study in mid-2026. We are focused on disciplined execution to deliver what could become the first disease-modifying therapy for patients living with FA.”
Highlights
- Published Cross-species Nonclinical Findings on Skin FXN Levels. In April, Larimar published a paper entitled Nomlabofusp Treatment Produces Frataxin Levels That Correlate Across Peripheral Tissues: Preclinical and Clinical Support for Surrogate Tissue Sampling in the peer-reviewed journal Clinical and Translational Science. The cross-species nonclinical findings consistently showed that treatment with nomlabofusp increases tissue frataxin (FXN) levels in target tissues (including heart, brain, dorsal root ganglia and skeletal muscle), with changes correlating between the tissues. These data were part of the package reviewed by the U.S. FDA in support of the potential use of skin FXN concentrations as a reasonably likely surrogate endpoint (RLSE) for accelerated approval. The open access article is now available online (https://ascpt.onlinelibrary.wiley.com/doi/10.1111/cts.70565).
- Breakthrough Therapy Designation: In February, the U.S. FDA granted Breakthrough Therapy Designation to nomlabofusp for the treatment of adults and children with FA. The designation was based on the FDA’s review of available clinical data from the Company’s ongoing OL study evaluating nomlabofusp in adult and pediatric patients with FA.
- FDA Meeting Comments Support Continued Alignment for BLA Submission: In February, following a recent Support for Clinical Trials Advancing Rare Disease Therapeutics (START) pilot program meeting with the FDA and review of preliminary clinical data for the nomlabofusp program, Larimar announced continued alignment with the FDA on BLA content including:
- FXN as Surrogate Endpoint: FDA reaffirmed willingness to consider use of FXN as novel surrogate endpoint and confirmed Larimar’s exposure-response analysis exploring the relationship between nomlabofusp exposures and clinical outcome measures is the type that could support the future BLA submission.
- Safety Dataset: FDA stated that the adequacy of the safety dataset will be a matter of review at the time of BLA submission.
- Global Phase 3 Study: FDA is aligned with plans to have the global confirmatory Phase 3 study underway at the time of BLA submission and confirmed that change from baseline in the Upright Stability Score (USS) (a subscale of mFARS) is a reasonable and clinically relevant primary endpoint for the planned Phase 3 study.
- Strengthened Balance Sheet: In February, Larimar announced a
$115.0 million underwritten public offering of common stock, including the exercise in full of the underwriters’ option to purchase additional shares, that included new and existing leading healthcare investors, resulting in net proceeds of$107.6 million and extending its projected cash runway into the second quarter of 2027.
Upcoming Milestones
- Topline OL Study Data in Second Quarter of 2026: Larimar plans to report topline data from the OL study that is intended to support BLA submission in the second quarter of 2026.
- Global Confirmatory Phase 3 Study: Plan to initiate dosing of first patient mid-2026.
- BLA Submission: Type B meeting with FDA scheduled later in Q2 to align on the overall BLA data package readiness. Pending FDA feedback, Larimar is planning to seek accelerated approval in a rolling BLA with submission of nonclinical and clinical modules in June 2026; submission of the final modules including the CMC module expected in second half of 2026. Targeting first half 2027 launch, if approved.
