We present the analytic calculation of the leading-order three-point energy correlator (EEEC) in hadronic Higgs decays, including both the gluon-initiated channel $H\to gg+X$ and quark-initiated channel $H\to q\overline{q}+X$ . The phase-space integration is evaluated directly using Mandelstam variables $s_{ij}=(p_i+p_j{)}^2$ , and the appearing square roots can be rationalized by either conformal ratios or celestial coordinate variables. Throughout the calculation, we observe the same transcendental function space as in $\mathcal{N}=4$ super–Yang-Mills theory and $e^{+}{e}^{-}\to \text{hadrons}$ . Different infrared limits are also explored using the full analytic result, offering the fixed-order data for EEEC factorization and resummation. Given its nontrivial shape dependence, the EEEC presents an excellent opportunity to explore the dynamics of gluon jets originating from the $H\to gg$ decay channel at future lepton colliders.
