We study the Higgs-boson mass spectrum of a classical scale-invariant realization of the two-Higgs-doublet model (SI-2HDM). The classical scale symmetry of the theory is explicitly broken by quantum loop effects due to gauge interactions, Higgs self-couplings and top-quark Yukawa couplings. We determine the allowed parameter space compatible with perturbative unitarity and electroweak precision data. Taking into account the LEP and the recent LHC exclusion limits on a Standard-Model-like Higgs boson H(SM), we obtain rather strict constraints on the mass spectrum of the heavy Higgs sector of the SI-2HDM. In particular, if M_H(SM) ~ 125 GeV, the SI-2HDM strongly favours scenarios, in which at least two of the charged or neutral Higgs bosons are generically degenerate and have masses close to 400 GeV, whilst the third one is lighter than ~500 GeV.
