* Dun & Bradstreet Corp. warned that its third-quarter and full-year profit will drop from a year ago and won’t meet analysts’ expectations because of an unexpected decline in U.S sales. The business information provider said third-quarter profit won’t meet estimates of 40 cents to 41 cents a share. It expects profit for the year to be $1.62 to $1.65 a share, about 10 cents lower than expected. Per-share earnings were 37 cents in the 1998 third quarter and $1.57 for the full year. The company issued its warning after the close of regular U.S. trading.
