Abstract: The European Strategy for Particle Physics identifies an $e^+e^-$ Higgs factory as its top priority and the first step towards an ultra-high energy future hadron collider. The Future Circular Collider is being proposed at CERN to address these goals. The Future Circular Collider includes an electron-positron collider: FCC-ee, which will be followed by an energy-frontier hadron collider: FCC-hh. New long-lived particles are connected to many new physics models and could be the key to new physics discoveries at FCC-ee. This contribution presents an ongoing sensitivity analysis for exotic Higgs boson decays to long-lived particles at FCC-ee using the FCCAnalyses framework. The study targets the production of a Higgs boson in association with a Z boson in $e^+e^-$ collisions at 240 GeV, with the Higgs boson decaying into two long-lived scalars. This builds upon previous work with improved statistics and a refined analysis strategy
