The extent of the company's withdrawal from the exchange markets will likely be the key focus during the earnings conference call.
Rate submissions for 2017 plans are due May 11 for the states on the Healthcare.gov federal exchange. United offered plans in 36 states this year. So far, the company has confirmed it will exit three markets: Arkansas and Georgia, where it saw sharp losses in 2015, and Michigan.
"I think all the insurance companies deep down think there's a future in [the] direct to consumer market. I don't they want to leave, unless they feel that they have to," said Katherine Hempstead, senior director at the non-profit Robert Wood Johnson Foundation.
Yet Hempstead said it was not surprising United was giving up on the Georgia market. In order to compete, she said the insurer priced below competitors, attracting patients who were sicker and thus racked up higher health costs.
"They had a lot of hospitalizations, above the median, and it just looked like their enrollment was very chaotic," Hempstead said, as a number of members dropped coverage part way through the year.
"If you look at who else is in the market… you can imagine [United] thinking, 'there's not a good future here'," she added.
Leerink analyst Ana Gupte said United's withdrawal from state exchanges could benefit its rivals in their efforts to gain regulatory approval for their respective mergers. That list includes Aetna, Humana, Anthem and Cigna.
"We expect these exits place the Obama Administration in a position where they particularly need Aetna and Anthem to play in these markets," Gupte wrote in a recent note to clients.
Already, a number of state regulators have given their approval of the deals on condition that Anthem and Aetna to maintain or in some cases expand their Obamacare exchange plan offerings.
"We see this as potentially acting as a positive influence on deal close to make it viable for these companies to subsidize these losses as a public service to consumers through the synergies generated by the proposed acquisitions," wrote Gupte.
