Capital One (COF) previously announced last quarter that it would issue new Walmart cards, but its announcement last night that it will buy the Walmart card portfolio from Synchrony (SYF) should mean that cards will be re-issued and that interchange and other fees associated with spending on those cards will, once converted, accrue to Capital One, explained Stephens analyst Brett Huff. As Capital One's card issuing processor, the news is likely a positive for TSYS (TSS), added Huff, who estimates this could equate to $15M a year, or about 40bps, of extra TSS net revenue growth and 4c, or an extra 1%, of pro forma EPS growth. While noting that he has worries about TSYS' guidance for FY19, Huff reiterates an Overweight rating and $96 price target on TSYS shares.
