East West Bancorp Q1 Earnings Miss on Higher Costs East West Bancorp's first-quarter 2019 adjusted earnings per share of $1.16 missed the Zacks Consensus Estimate of $1.22. However, the figure compares favorably with adjusted earnings of $1.13 reported in the prior-year quarter. Results were affected by rise in expenses, higher provisions for credit losses and decline in non-interest income. However, improvement in net interest income, and higher loans and deposits acted as tailwinds.
