JPMorgan analyst Philip Cusick views the 21% selloff in Uniti Group (UNIT) shares since the company's Q2 results on August 3 as overdone. He attributes the weakness to fears around Windstream's (WIN) dividend cut and notes Windstream shares are down 45% in the same period. The analyst looks at Uniti's lease with Windstream as "essentially secured debt" and sees no reason that Uniti would reduce or renegotiate its lease with Windstream in or out of bankruptcy. He estimates Uniti shares are now pricing in a 22%-28% lease reduction and subsequent 35%-44% dividend cut. Cusick, however, views Windstream's dividend cut as a positive for Uniti as it "strengthens the durability of the Windstream lease payment." He reiterates an Overweight rating on the shares with a $31 price target.
