FedEx "is exposed to risk from tariffs and potentially slower trade activity," UBS analysts wrote in a note. About 55 percent of FedEx revenue stems from its "global Express business," and UBS does "not expect" to see benefits from the company's $4.8 billion acquisition of TNT Express to "show up in the next few quarters."
On the other hand, UPS has "multiple ways to win," the firm said. UBS believes the company may be poised to show "improved Domestic Package margin performance and stronger operating income growth" next year, as UPS benefits from a more cost-effective business and increasing revenue.
"We expect UPS's Transformation initiative to generate significant cost savings," UBS said. This, along with UPS' expected $800 million to $1 billion "network initiatives," it said, "can support a transition to Domestic Package margin improvement in 2019" after the company's "weak margin performance the past several years."
UBS lowered its price target on FedEx to $256 per share from $283 per share and raised its price target on UPS to $125 per share from $121 per share.
Shares of UPS closed up over 1 percent in trading and have fallen over 5 percent this year, while FedEx stock closed down 1.5 percent, down over 7 percent this year.
While the UPS agreement with Teamsters has yet to be finalized, UBS wrote that it "may also facilitate growth."
"[A partnership with Teamsters] provides a labor cost structure which allows UPS to be more aggressive in offering Saturday & Sunday delivery," the firm said.
In the case of both companies, UBS said "the Amazon risk" was "a long term factor."
