Share repurchase transactions with Sanken Electric Co., LTD. (“Sanken”)

On July 23, 2024, the Company entered into a share repurchase agreement with Sanken (the “Share Repurchase Agreement”) pursuant to which the Company agreed to repurchase 38,767,315 shares of the Company’s common stock from Sanken in a privately negotiated transaction at a price per share equal to the price per share at which the underwriters in a public underwritten equity offering of shares of our common stock would purchase the shares (the “Equity Offering”). The repurchase of shares of common stock occurred in two separate closings, with the first closing taking place after the closing of the Equity Offering (the “First Closing”) and the second closing occurring after the receipt of the proceeds from borrowings under the Refinanced 2023 Term Loan Facility (the “Second Closing”). The First Closing of the share repurchase was conditioned upon the closing of the Equity Offering and certain other conditions, and the Second Closing of the share repurchase was conditioned upon the receipt of net proceeds of no less than $300,000 from the Refinanced 2023 Term Loan Facility. Pursuant to the terms of the Share Repurchase Agreement, Sanken reimbursed the Company for the expenses incurred by the Company in connection with the transactions contemplated by the Share Repurchase Agreement, and paid a facilitation fee of $35,000, which was recorded within additional paid-in-capital with the consolidated statements of changes in equity.

To fund the First Closing, the Company entered into an underwriting agreement (the “Underwriting Agreement”) with Barclays Capital Inc. and Morgan Stanley & Co. LLC, as representatives of the several underwriters (the “Underwriters”), on July 24, 2024, pursuant to which the Company agreed to sell 25,000,000 shares of the Company’s common stock to the Underwriters at a price of $23.16 per share. Under the terms of the Underwriting Agreement, the Company granted the Underwriters a 30-day option to purchase up to an additional 3,750,000 shares of the Company’s common stock at the same purchase price, which option was exercised in full prior to the closing of the Equity Offering.

On July 26, 2024, the Company completed the Equity Offering pursuant to the Underwriting Agreement of 28,750,000 shares of its common stock at a public offering price of $24.00 per share resulting in net proceeds to the Company of approximately $665,850, after deducting $24,150 of underwriting discounts. As described above, the Company used the net proceeds of the Equity Offering to complete the First Closing under the Share Repurchase Agreement.

On July 29, 2024, the Company completed the First Closing under the Share Repurchase Agreement, repurchasing 28,750,000 shares of the Company’s common stock for aggregate consideration of $628,256, which was the Equity Offering price, less the facilitation fee of $35,000, underwriting discounts, and reimbursable transaction expenses. The shares repurchased in the First Closing were retired.

On August 7, 2024, the Company completed the Second Closing under the Share Repurchase Agreement, repurchasing 10,017,315 shares of the Company’s common stock for aggregate cash consideration of $225,549, which was the Equity Offering price, less underwriting discounts and reimbursable transaction expenses. As described above, the Company used a portion of the proceeds from the Refinanced 2023 Term Loan Facility and existing cash on hand to complete the Second Closing. The shares repurchased in the Second Closing were also retired.

The Share Repurchase Agreement was accounted for as a forward repurchase contract as there were certain terms that could have caused the obligation not to be fulfilled. Accordingly, the contract was initially recorded as a liability at its fair value with subsequent remeasurements recognized in loss on change in fair value of forward repurchase contract until the completion of the First Closing and Second Closing. The Company recognized a loss of $34,752 as a result of the fair value forward repurchase contract in the condensed consolidated statements of operations.

In connection with the Share Repurchase Agreement, the Company entered into a Second Amended and Restated Stockholders Agreement with Sanken (the “Second Amended and Restated Stockholders Agreement”), which amended and restated the Amended and Restated Stockholders Agreement, dated as of June 16, 2022, by and among the Company, Sanken and OEP SKNA, L.P. (“OEP”). The Second Amended and Restated Stockholders Agreement, which became effective in accordance with its terms on July 29, 2024, removed OEP as a party and amended certain rights and obligations of the Company and Sanken.
