JP Morgan warns 3M's troubles will continue, may cut dividend 'after 37 straight years of increase'

J.P. Morgan analyst Stephen Tusa said in a note that 3M's "premium valuation is unjustified by undifferentiated fundamentals," with growth excluding mergers and acquisitions likely decelerating and benefits to margins fading. 3M's quarterly dividend is "on watch for a cut, after 37 straight years of increase," Tusa said. J.P. Morgan pointed to 3M's growing list of liabilities as another risk to the company's earnings-per-share growth.
