“We are off to a strong start in 2023. We achieved a medical margin of $39.2 million or 13.1% as a percentage of capitated revenue for the quarter, a key metric for validating the effectiveness of P3’s model. As a result of the first quarter strength, we are increasing our Adjusted EBITDA guidance today,” said Dr. Sherif Abdou, CEO of P3.

“It is the mission of P3 to provide every patient with comprehensive care. We work to ensure each patient has a 360-degree review of their health when we onboard them. We then engage with them to provide solutions and proactively address possible health risks. By improving the health of our patients, we can lower overall costs of care in a model where we believe the patient, providers, payors and ultimately our shareholders win,” Dr. Abdou concluded.

(1)Adjusted EBITDA, Adjusted EBITDA per member, per month (“PMPM”), medical margin and network contribution are non-GAAP financial measures. For reconciliations of these measures to the most directly comparable GAAP measures and more information regarding the Company’s use of non-GAAP financial measures, please see the section titled “Non-GAAP Financial Measures.”

(2)The Company is not able to provide a quantitative reconciliation of guidance for Adjusted EBITDA loss, medical margin and medical margin PMPM to net income (loss), operating loss and operating loss PMPM, the most directly comparable GAAP measures, respectively, and has not provided forward-looking guidance for net income (loss), operating loss or operating loss PMPM because of the uncertainty around certain items that may impact net income (loss), operating loss or operating loss PMPM that are not within our control or cannot be reasonably predicted without unreasonable effort. For more information regarding the non-GAAP financial measures discussed in this press release, please see “Non-GAAP Financial Measures” below.

In addition to the financial results prepared in accordance accounting principles generally accepted in the U.S (“GAAP”), this press release contains certain non-GAAP financial measures as defined by the SEC rules, including Adjusted EBITDA and Adjusted EBITDA PMPM, medical margin and network contribution. EBITDA is defined as GAAP net income (loss) before (i) interest, (ii) income taxes and (iii) depreciation and amortization. Adjusted EBITDA is defined as EBITDA, further adjusted to exclude the effect of certain supplemental adjustments, such as (i) mark-to-market warrant gain/loss, (ii) premium deficiency reserves, (ii) equity-based compensation expense and (vi) certain other items that we believe are not indicative of our core operating performances. Adjusted EBITDA PMPM is defined as Adjusted EBITDA divided by the number of at-risk Medicare Advantage members each month divided by the number of months in the period. We believe these non‐GAAP financial measures provide an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing our financial measures with other similar companies. Medical margin represents the amount earned from capitation revenue after medical claims expenses are deducted.

Medical claims expenses represent costs incurred for medical services provided to our members. As our platform grows and matures over time, we expect medical margin to increase in absolute dollars; however, medical margin PMPM may vary as the percentage of new members brought onto our platform fluctuates. New membership added to the platform is typically dilutive to medical margin PMPM. Furthermore, in light of COVID-19, we continue to evaluate the ultimate impact of the pandemic on medical margin. We define network contribution as total operating revenue less the sum of: (i) medical claims expenses and (ii) other medical expenses including physician compensation expense related to surplus sharing and bonuses and other direct medical expenses incurred to improve care for our members. We believe this metric provides insight into the economics of the P3 Care Model, as it includes all medical claims expense associated with our members’ care as well as partner compensation and additional medical costs we incur as part of our aligned partnership model. Other medical expenses are largely variable and proportionate to the level of surplus in each respective market, among other cost factors. We do not consider these non‐GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. These non-GAAP financial measures are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non‐GAAP financial measures. In addition, other companies may calculate non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. The tables at the end of this press release present a reconciliation of Adjusted EBITDA to net income (loss) and Adjusted EBITDA PMPM to net income (loss) PMPM, and medical margin and network contribution to operating income (loss) which are the most directly comparable financial measures calculated in accordance with GAAP.
