INVESTMENT HIGHLIGHTS Rare disease
focused, clinical-staged biotechnology company developing a novel, once-daily, inhaled, disease modifying rapamycin formulation (LAM-001) across multiple Phase 2 programs: PH-ILD (~200K US/EU)1 –Current therapies are limited to vasodilation,
not disease modifying2. Promising Ph 2a data on top of standard of care presented ATS 2026; Ph 2b expected to initiate mid-2026. BOS (~30K US/EU)3 - Severe complication of and leading cause of death post lung transplantation4. Positive,
retrospective data from clinical utilization of oral rapamycin support an ongoing Ph 2 trial with data expected 1Q 2027. SAPH (~60K US/EU)5 - Severe complication of sarcoidosis with no approved therapy (PH WHO group 5). Ph 2 trial expected to
initiate in 4Q 2026, supported by proof-of-concept clinical efficacy data from completed PH study. Efficient 505(b)2 development pathway for lead program (LAM-001), with strong IP coverage expected to the mid 2040's US/EU Orphan Disease Status

information, NIH NLM; Revised 5/2026 LIMITATIONS OF ORAL RAPAMYCIN SYSTEMIC EXPOSURE WITH SIGNIFICANT SAFETY RISKS: Oral Rapamune® Key Label Warnings and Precautions: Angioedema, Fluid Accumulation and Impairment of Wound Healing,
Hyperlipidemia, Decline in Renal Function, Proteinuria, Latent Viral Infections, Male Infertility, Embryo-Fetal Toxicity LIMITED LUNG EXPOSURE: Systemic toxicity limits oral dosing levels and may preclude sufficient lung exposure LOW AND VARIABLE
ORAL BIOAVAILABILITY*: Requiring inconvenient plasma monitoring and frequent dose adjustments We believe these limitations preclude the adoption of oral rapamycin in pulmonary diseases where the mTOR pathway has been clearly implicated

Based on non-clinical and clinical
studies conducted by the Company, Sirolimus (Rapamycin) prescribing information. NIH NLM; Revised 5/2026 No head-to-head clinical trials have been conducted evaluating LAM-001 and Rapamycin. Differences exist between study or trial designs and
participant characteristics, and caution should be exercised when comparing data across studies SOLUTION: LAM-001 DESIGNED FOR IMPROVED PULMONARY DELIVERY OF RAPAMYCIN TARGETED DELIVERY: Direct lung delivery à higher local exposure versus oral
or nebulized formulations IDEAL PHYSICAL CHEMICAL PROPERTIES FOR LUNG DELIVERY: Enhanced lung exposure and potential improved efficacy in pulmonary diseases MINIMIZED SYSTEMIC EXPOSURE AND WELL-TOLERATED SAFETY PROFILE: Reduced systemic side effects
compared to oral rapamycin CONVENIENT ADMINISTRATION: Easy-to-use once-a-day dry powder inhaler (DPI) designed to enhance patient compliance; fixed dose with no need for blood level monitoring (required with oral rapamycin due to low and variable
oral bioavailability)
