  The measurement of (anti)nuclei production in pp, p-A and A-A collisions at
ultrarelativistic energies is important to understand hadronization. The
excellent tracking and particle identification capabilities of ALICE make it
the most suited detector at the LHC to study light (anti)nuclei produced in
high-energy hadronic collisions. (Anti)nuclei with mass numbers up to 4, such
as (anti)deuterons, (anti)tritons, (anti)$^3$He and (anti)$^4$He have been
successfully identified in ALICE at midrapidity ($|\eta|<$0.9). In this
contribution, multiplicity dependent results on the yields, nuclei-to-protons
ratios as well as the coalescence parameter $B_{\mathrm A}$ as a function of
the charged-particle multiplicity are presented and compared with the
expectations of coalescence and statistical hadronization models (SHM) to
provide insight into their production mechanism in heavy-ion collisions.
