As previously reported, Northland analyst Tim Savageaux downgraded Adtran (ADTN) to Market Perform from Outperform following the company's Q2 report and Q3 revenue guidance that met consensus, stating that he views the shares as fairly valued given that he believes the earnings power needed to support a higher share price is "still a ways off." While Adtran is "slowly but clearly diversifying away" from CenturyLink (CTL), Savageaux has lowered expectations for any snap-back at CenturyLink and sees slower than expected progress at other U.S. Tier 1 telecom companies, he tells investors. The analyst, who reduced his estimates for 2019, cut his price target on Adtran shares to $17 from $20.
