(collectively, the “Wynnchurch Funds”). Pursuant to the Stockholders Agreement, each of the Pamplona Fund and the Wynnchurch Funds have agreed, among other things, to vote their shares of Common Stock to elect members of the board of directors of the Issuer as set forth therein. Because of the relationship between the Pamplona Fund and the Wynnchurch Funds as a result of the Stockholders Agreement, the Reporting Persons may be deemed, pursuant to Rule 13d-3 under the Act, to beneficially own the shares of Common Stock beneficially owned by the Wynnchurch Funds and/or to constitute a “group” with the Wynnchurch Funds. Each Reporting Person disclaims beneficial ownership of the shares of Common Stock beneficially owned by the Pamplona Fund. None of the 61,476,581 shares of Common Stock held by the Pamplona Fund, as reflected in the Schedule 13G filed by the Pamplona Fund and its affiliates on February 11, 2022, are reflected in this report.

CUSIP No. 51819L107

(Wynnchurch Capital Partners IV, L.P. sold 2,702,021 shares of Common Stock and WC Partners Executive IV, L.P. sold 81,376 shares of Common Stock.) The Issuer sold an equal number of shares of Common Stock in a concurrent public offering and used the net proceeds thereof to purchase the shares from the Pamplona Funds and the Wynnchurch Funds.

All percentages calculated in this Schedule 13G are based upon an aggregate of 119,900,905 shares of Common Stock outstanding as of December 30, 2021 as indicated in the Issuer’s Form S-1 filed on January 4, 2022.
