Mastercard Incorporated MA reported second-quarter earnings of $1.89 per share, beating the Zacks Consensus Estimate by 3.9%.

Its numerous acquisitions have aided revenue growth.However, escalating costs will put pressure on the company’s bottom line.

Nevertheless, its strong balance sheet enables business investment, thereby driving growth.Mastercard carries a Zacks Rank #3 (Hold).Among the companies in the same space that have reported earnings, Visa Inc.
