BOK FINANCIAL CORPORATION ● ● Exhibit 99 ( a ) CEO Commentary Steven G. Bradshaw , president and chief executive officer , stated , " The organization eclipsed $ 160 million in net income for the first time on another stellar , broad - based contribution from our Wealth Management team and stable net interest revenues . Additionally , growth in our Healthcare portfolio and steady core C & I this quarter provides a solid foundation as we head into the back half of 2021. While growth in other areas of the loan portfolio remains somewhat constrained by near - term labor and supply chain disruptions , our customers ' confidence about future growth is very high , which reaffirms our outlook for the remainder of this year . " NASD : BOKF BOK Financial Corporation Reports Quarterly Earnings of $ 166 million or $ 2.40 Per Share in the Second Quarter Bradshaw continued , " While our top - line strength this quarter was impressive , equally strong was our discipline around operating costs and our excellent credit outcomes . We continue to hold the line on many expense saves gained through the pandemic , driving meaningful earnings leverage . Credit also continues to be a clear differentiator , as oil and natural gas prices rebounded to multi - year highs . Non - performing assets and potential problem loans were both down significantly , and credit costs continue to be at the low end of our historical range . Altogether , this quarter demonstrates just how effectively we can execute on both the top and bottom line and build shareholder value .
