Expected Performance Results from Upgraded LHCb and SMOG2

The LHCb experiment at CERN is a forward spectrometer with a unique heavy-ion physics programme exploiting the collisions of circulating proton and lead beams and, since 2015, is pioneering fixed-target physics at the LHC with the injection of helium, neon, and argon in the accelerator beam-pipe. A further extension of both programmes is now expected along with the experiment upgrade. In this document, the expected performance for data reconstruction and the related physics opportunities are discussed.
