Over the weekend, we received an encouraging update about the June launch of Costco Wholesale's (COST) - Get Report new loyalty-card program with Visa (V) - Get Report and Citigroup (C) - Get Report . Last year, Costco announced it was ending its 16-year partnership with American Express (AXP) - Get Report , in which only AmEx credit cards were accepted at the warehouse club, after striking a deal for a new card that would be issued by Citi and processed on the Visa network.

The new Costco Anywhere Visa Card -- which will be mailed to current cardholders in May and become active on June 20 -- not only comes at a lower fee to Costco (expected to benefit annual earnings by 25 cents a share), but also offers perks that are significantly greater than legacy AmEx (as illustrated in Figure 1 below), which in turn should incentivize spending across all Costco locations.

The change will be seamless for current members as any rewards earned on the Amex-Costco card will be automatically transferred over to the new card. In addition, the month-long lag between when members receive the card and when the card becomes active should be enough time to avoid any significant hiccups in the changeover process.

In our view, the deal creates a mutually beneficial relationship for Costco, its members and Visa alike. We remain bullish on both COST and V for the long term and on Monday raised our price target on COST to $175 from $170 to reflect higher comp expectations (28 times 2017 EPS of $6.25) driven by enhanced loyalty. Meanwhile, on Tuesday we added to our position in Visa, given progress the company has made in its expansion into China.
