Executive Summary

• OS Therapies reported Q3 2024 results with a net operating loss of $2.875M and GAAP net loss per share of $0.18 on 15.897M weighted-average shares; management attributed the larger loss primarily to IPO-related expenses, while reiterating the company remains pre-revenue .
• The quarter’s key catalyst is the expected December 2024 topline readout from the fully enrolled, potentially pivotal Phase 2b OST-HER2 trial in resected, recurrent osteosarcoma; management intends to promptly engage the FDA thereafter .
• Corporate execution highlights: completion of final patient dosing in Phase 2b and acceptance into Johnson & Johnson JLABS, positioning the company for regulatory engagement and potential commercialization steps post-data .
• Consensus estimates from S&P Global for Q3 2024 were unavailable at time of analysis due to access limits, so we cannot benchmark EPS/revenue vs. Street; note the company is pre-revenue and did not provide financial guidance metrics .

What Went Well and What Went Wrong

• What Went Well

  • Completed treatment phase for the Phase 2b OST-HER2 trial (41 patients dosed across 21 U.S. sites), with topline data expected in December 2024—keeps regulatory timeline intact .

  • Operating loss increased year over year as IPO-related expenses elevated operating costs; Q3 2024 operating loss was $2.875M vs. $2.006M in Q3 2023 .
  • No revenue yet; management reiterates the company is pre-revenue and anticipates monetization via potential Priority Review Voucher (PRV) upon approval and licensing as milestones de-risk—timing remains contingent on clinical and regulatory outcomes .
  • Street benchmarking unavailable: S&P Global consensus EPS and revenue for Q3 2024 could not be retrieved due to access limits, limiting comparison versus expectations .

Estimates Context

Key Takeaways for Investors

• December 2024 topline readout for OST-HER2 is the pivotal catalyst; management intends to quickly engage the FDA post-data, with multiple expedited designations supporting potential acceleration .
• Operating loss increased versus prior year given IPO-related expenses; watch for normalization of run-rate post-IPO and any changes to cash runway disclosures following the data readout .
• Monetization path articulated: if approved, the company expects to sell a PRV and pursue licensing revenues as milestones de-risk—key to funding the transition into commercialization .
• Execution de-risking continues: final patient dosing completed; acceptance into J&J JLABS adds ecosystem support that may aid clinical, regulatory, and potential commercialization initiatives .
• Pre-revenue status persists; trading setup remains binary around the December data; absence of Street consensus data this quarter limits benchmarking, but the narrative is squarely clinical/regulatory over financials .
• Share structure context from Q2: 20.85M shares outstanding post-IPO with lockups and limited float (1.86M tradable) may amplify volatility around December readout; monitor any updates ahead of the event .
