Management Comments

• We believe LB-102 has the potential to be the first benzamide antipsychotic drug approved for neuropsychiatric disorders in the United States.
• We believe LB-102, if approved, can become a mainstay of psychiatric practice by offering a potentially attractive alternative to branded and generic therapeutics.
• Our current strategy is to utilize our recently completed Phase 2 trial in acute schizophrenia as one of two adequate and well-controlled trials required for FDA approval.
• We believe LB-102 has the potential to treat a broad range of patients living with schizophrenia by addressing positive, negative, and cognitive symptom domains of the disease.
• We believe there is significant opportunity in the clinical development and commercial potential of LB-102 in mood disorders and other psychosis-related indications.
• We believe that the success of the 50 mg dose in our schizophrenia Phase 2 trial affords the opportunity to develop an LAI.
• We intend to retain commercialization rights in the United States and may opportunistically evaluate potential commercial collaborations outside of the United States.
• We believe that our existing cash, cash equivalents and marketable securities, including net proceeds from our private placement, will be sufficient to meet our anticipated operating and capital expenditure requirements into the second quarter of 2029.

Industry Context

StockSavvy.ai notes that LB Pharmaceuticals is targeting a significant market, with the U.S. branded antipsychotic market valued at approximately $12 billion in 2024. The strategy to expand LB-102 beyond schizophrenia into mood disorders like bipolar depression and adjunctive MDD aligns with industry trends where antipsychotics with broader indications have achieved substantial revenue increases. The company's focus on a differentiated tolerability profile and potential impact on negative and cognitive symptoms addresses persistent unmet needs, as current therapies often have significant side effects and limited efficacy in these areas. The development of an LAI formulation is also a strategic move to enhance compliance and competitive positioning, given the limited options in this segment.

Comparison to Industry Standards

• LB-102's Phase 2 trial demonstrated a placebo-adjusted PANSS total score reduction of 5.0 points (50mg) to 6.8 points (100mg), with effect sizes ranging from 0.61 to 0.83. This compares favorably to other approved antipsychotics like Caplyta (5.8-4.2 points), Cobenfy (9.6-8.4 points), Rexulti (7.6-6.5 points), and Vraylar (7.6-10.4 points), suggesting competitive efficacy.
• The observed low rates of Extrapyramidal Symptoms (EPS), including akathisia (1.0% at 50mg, 5.6% at 75mg/100mg vs. 3.7% placebo), minimal sedation, few gastrointestinal side effects, and no orthostasis in the Phase 2 trial position LB-102 as potentially class-leading in tolerability among D2 antagonists and partial agonists. This is a significant advantage compared to many existing antipsychotics known for burdensome side effects like EPS (Vraylar 15-19%, Rexulti 6% akathisia) and metabolic changes (Caplyta, Rexulti, Vraylar warnings).
• Amisulpride, the derivative of LB-102, was ranked as the second most effective antipsychotic after clozapine in a 2019 Lancet meta-analysis and more effective than risperidone (a first-line treatment) at reducing overall schizophrenia symptoms. Its effect size was also greater than Cobenfy (0.56) in a 2025 study.
• Amisulpride showed lower weight gain compared to other antipsychotics in a 2014 meta-analysis and significantly lower long-term weight gain than olanzapine in a 2002 head-to-head trial (plateauing at ~1kg vs. ~5kg for olanzapine). LB-102's observed 1.6 kg placebo-adjusted weight gain in 4 weeks, without clinically meaningful metabolic changes, suggests a potentially better metabolic profile than some competitors.
• The observed impact on negative symptoms and cognitive performance in LB-102's Phase 2 trial addresses areas where currently approved therapies, such as firstand second-generation antipsychotics, often fall short, with no FDA-approved treatments for predominantly negative symptoms or cognitive impairment associated with schizophrenia.

Management Changes

Corporate Governance

Legal Proceedings

• The company is not a party to any pending litigation that would have a material adverse effect on its results of operations, financial condition, or cash flows.

Related Party Transactions

• In August 2023, the company entered into Amended and Restated Royalty Agreements with certain existing investors, co-founders, former directors, and executive officers (including Zachary Prensky, Andrew Vaino, Ph.D., and Marc Panoff).
• These agreements obligate the company to pay aggregate royalties of up to 2.75% of net sales of LB-102 worldwide through December 31, 2035, increasing to up to 3.25% thereafter in perpetuity.
• No consideration was received by the company as part of these Amended and Restated Royalty Agreements.
• As of December 31, 2025, certain former and current officers and their affiliates held 1.13% of these future royalties.

Stakeholder Impact

• **Shareholders:** Potential for significant value creation if LB-102 successfully navigates clinical trials and gains regulatory approval, especially given the large market opportunity. However, dilution from future capital raises and the impact of royalty agreements on future revenue streams are considerations. Material weaknesses in internal controls could affect investor confidence.
• **Patients (Schizophrenia, Bipolar Depression, MDD):** Potential for a new, effective, and well-tolerated treatment option (LB-102) that addresses positive, negative, and cognitive symptoms, improving quality of life and adherence compared to existing therapies.
• **Employees:** Increased headcount and expansion of operations are expected, offering growth opportunities. However, a recent Reduction in Force (RIF) impacted several employees, and the company's ability to attract and retain key personnel is crucial for success.
• **Management:** Significant time and resources will be devoted to new compliance initiatives and corporate governance practices as a public company. The Incentive Compensation Recoupment Policy introduces additional accountability.
• **Third-Party Manufacturers/Suppliers:** Continued reliance on CDMOs and other third parties for manufacturing and clinical trial services, highlighting the importance of strong partnerships and compliance with regulatory standards.
• **Regulatory Authorities:** The company is actively engaging with the FDA, with positive feedback on its Phase 2 trial potentially streamlining the approval process. Compliance with evolving U.S. and foreign regulations is a continuous effort.

Next Steps

• Continue the six-week Phase 3 trial (NOVA-2) of LB-102 in acute schizophrenia, with topline data expected in the second half of 2027.
• Initiate an outpatient, open label trial (NOVA-3) concurrently with the Phase 3 trial to accrue requisite safety population for NDA submission (approximately 900 patients).
