** SUSS MicroTec SMHNn.DE shares sink about 12% after the German chip equipment manufacturer posted worse-than-expected 2026 guidance
** The company expects an EBIT margin for 2026 between 8% and 10%, below a company-compiled consensus of 11.6%
** Jefferies says margin guidance is disappointing, adding sales decline and rising R&D expenses are affecting it
** It, however, flags 2026 is a transition year and expects revenue and margin improvement from 2027
** SUSS MicroTec shares are on track for their worst day since late October if losses hold
