The company reported first-quarter numbers on May 10. It listed capitated revenue of $298.7 million, up 11%, year over year and 18% sequentially. Capitated revenue is paid to a healthcare provider or organization on a per-member, per-month (PMPM) basis.

The company also reported a net loss of $52.4 million, up 14% from the same period a year ago and a big improvement from the $532.3 million it lost in the fourth quarter.

P3 also released yearly guidance, saying it expected revenue to be between $1.2 billion and $1.25 billion, up from $1 billion in 2022. It also said it expected to have between 115,000 to 120,000 MA members by the end of the year, compared to 100,400 MA members at the end of 2022.
