•Company has six months to regain compliance with the minimum price criteria for continued listing on the NYSE

•Company remains focused on executing its Growth Plan and on delivering results and shareholder value

NEW YORK – March 29, 2024 – MultiPlan Corporation (NYSE: MPLN) (“MultiPlan” or the “Company”) announced today that it received notice (the “Notice”) on March 28, 2024 from the New York Stock Exchange (the “NYSE”) that, as of March 27, 2024, it was not in compliance with the continued listing standard set forth in Section 802.01C of the NYSE’s Listed Company Manual (“Section 802.01C”) because the average closing price of the Company’s Class A Common Stock (the “Common Stock”) was less than $1.00 per share over a consecutive 30 trading-day period.

Pursuant to Section 802.01C, the Company has a period of six months following the receipt of the Notice to regain compliance with the minimum price criteria. In accordance with Section 802.01C, the Company plans to notify the NYSE within 10 business days of its receipt of the Notice of its intent to cure the deficiency, which may include, if necessary, effecting a reverse stock split, subject to approval by the Board of Directors and stockholders of the Company.

The Company may regain compliance with the minimum price criteria at any time during the six-month cure period if, on the last trading day of any calendar month during the cure period, the Company has (i) a closing share price of at least $1.00, and (ii) an average closing share price of at least $1.00 over the 30 trading-day period ending on the last trading day of that month.

The Notice has no immediate impact on the listing of the Common Stock, which will continue to be listed and traded on the NYSE during this period, subject to the Company’s compliance with the other continued listing requirements of the NYSE.

The Notice does not affect the Company’s business operations or its reporting obligations with the Securities and Exchange Commission, nor does it conflict with or prompt default under any of the Company’s material debt or other agreements. The Company fully intends to regain compliance and will take necessary action to ensure that the Common Stock continues to be listed on the NYSE. The Company remains focused on executing its Growth Plan and on delivering results and shareholder value.
