Cadbury-parent Mondelez International forecast a bigger-than-estimated drop in its annual profit on Tuesday, signaling pressures from higher costs, including from surging cocoa prices, sending its shares down nearly 6% after the bell.

The company is specifically focused on its chocolate business as it navigates cocoa cost inflation, Chief Executive Dirk Van de Put said. The company previously said it expects to raise prices.

MDLZ's fourth-quarter earnings decline year over year amid a challenging operating environment marked by cocoa cost inflation.
