Based on arXiv:1801.08849, this talk will look at how Higgs alignment can be realised naturally in a low energy type-II Higgs doublet model, originating from Dirac gaugino models with extended supersymmetry at higher energies. It will be discussed how alignment, predicted at tree-level at the scale of the extended supersymmetry, is maintained in the low energy effective theory even after including quantum corrections and increasing the extended supersymmetry scale. A precision study is presented, alongside the associated implications for the Higgs mass and experimental constraints on the scale of the superpartners.
