Scilex Bio, Inc. Acquisition On April 17, 2025, the Company and IPMC Company (“IPMC”) jointly established Scilex Bio, a newly formed legal entity created to develop and commercialize KDS2010, a next-generation reversible MAO-B Inhibitor, a novel inhibitor of aberrant GABA production in reactive astrocytes for the treatment of obesity and neurodegenerative diseases including Alzheimer’s disease in the United States. At formation, the Company contributed 5,000,000 shares of common stock, par value $0.00001 per share, of Semnur (the “Semnur Common Stock”) to Scilex Bio in exchange for a 60% equity interest. IPMC contributed certain license and commercialization rights to KDS2010 in exchange for a 40% equity interest. The Company evaluated Scilex Bio under the variable interest entity (“VIE”) model in accordance with ASC 810 and concluded that Scilex Bio is a VIE because it lacked sufficient equity at risk to finance its activities without additional subordinated support. The Company was determined to be the primary beneficiary of Scilex Bio based on its power to direct key activities through its majority board representation and its significant economic exposure through its 60% equity interest. As a result, the Company consolidated Scilex Bio beginning on the formation date. The Company further concluded that Scilex Bio did not meet the definition of a business under ASC 805, Business Combinations. Therefore, the transaction was accounted for as an asset acquisition under ASC 805-50. As the shares of Semnur Common Stock were contributed by the Company (the parent) to an entity under common control, they were recorded at their historical carrying value of $0 in the consolidated condensed financial statements. The KDS2010 license rights contributed by IPMC were recorded at 40% of their estimated fair value of $8.1 million for $4.4 million and immediately expensed as in-process research and development (“IPR&D”) in accordance with ASC 730, Research and Development, as the contributed IP had no alternative future use. A current liability of $1.1 million was also recognized for the initial upfront payment due under the licensing arrangement (further discussed below). Additionally, the Company recorded $1.5 million in additional paid-in capital as a capital contribution. Net loss from Scilex Bio attributable to the noncontrolling interest was $1.7 million. As of June 30, 2025, Scilex Bio had not commenced revenue-generating operations and remains focused on early-stage development efforts for KDS2010. The Company will reassess its primary beneficiary status and the VIE conclusion for Scilex Bio upon the occurrence of any reconsideration events. In connection with the formation of Scilex Bio, on April 17, 2025, the entity entered into a license agreement with IPMC and NeuroBioGen Company (“NBG”), under which it obtained exclusive rights to develop and commercialize KDS2010 globally, except for Korea. Under the terms of the agreement, Scilex Bio may be required to make aggregate payments of up to KRW 6.5 trillion (approximately $4.8 billion) to NBG, consisting of an upfront fee of KRW 1.5 billion (approximately $1.1 million), and KRW 68.5 billion (approximately $50.7 million) contingent upon the achievement of specified development, regulatory and commercial milestones. Scilex Bio is also required to pay royalties equal to 5% of net sales of licensed products, payable quarterly until the expiration of the last-to-expire licensed patent. Aggregate payments to NBG are capped at KRW 6.5 trillion (approximately $4.8 billion). As of June 30, 2025, only the first tranche of the upfront fee (KRW 1.5 billion or approximately $1.1 million) had become payable and was recorded as a current liability.

Scilex Bio, Inc. Acquisition

On April 17, 2025, the Company and IPMC Company (“IPMC”) jointly established Scilex Bio, a newly formed legal entity created to develop and commercialize KDS2010, a next-generation reversible MAO-B Inhibitor, a novel inhibitor of aberrant GABA production in reactive astrocytes for the treatment of obesity and neurodegenerative diseases including Alzheimer’s disease in the United States. At formation, the Company contributed 5,000,000 shares of common stock, par value $0.00001 per share, of Semnur (the “Semnur Common Stock”) to Scilex Bio in exchange for a 60% equity interest. IPMC contributed certain license and commercialization rights to KDS2010 in exchange for a 40% equity interest.

The Company evaluated Scilex Bio under the variable interest entity (“VIE”) model in accordance with ASC 810 and concluded that Scilex Bio is a VIE because it lacked sufficient equity at risk to finance its activities without additional subordinated support. The Company was determined to be the primary beneficiary of Scilex Bio based on its power to direct key activities through its majority board representation and its significant economic exposure through its 60% equity interest. As a result, the Company consolidated Scilex Bio beginning on the formation date.

The Company further concluded that Scilex Bio did not meet the definition of a business under ASC 805, Business Combinations. Therefore, the transaction was accounted for as an asset acquisition under ASC 805-50. As the shares of Semnur Common Stock were contributed by the Company (the parent) to an entity under common control, they were recorded at their historical carrying value of $0 in the consolidated condensed financial statements. The KDS2010 license rights contributed by IPMC were recorded at 40% of their estimated fair value of $8.1 million for $4.4 million and immediately expensed as in-process research and development (“IPR&D”) in accordance with ASC 730, Research and Development, as the contributed IP had no alternative future use. A current liability of $1.1 million was also recognized for the initial upfront payment due under the licensing arrangement (further discussed below).

Additionally, the Company recorded $1.5 million in additional paid-in capital as a capital contribution. Net loss from Scilex Bio attributable to the noncontrolling interest was $1.7 million.

As of June 30, 2025, Scilex Bio had not commenced revenue-generating operations and remains focused on early-stage development efforts for KDS2010. The Company will reassess its primary beneficiary status and the VIE conclusion for Scilex Bio upon the occurrence of any reconsideration events.

In connection with the formation of Scilex Bio, on April 17, 2025, the entity entered into a license agreement with IPMC and NeuroBioGen Company (“NBG”), under which it obtained exclusive rights to develop and commercialize KDS2010 globally, except for Korea. Under the terms of the agreement, Scilex Bio may be required to make aggregate payments of up to KRW 6.5 trillion (approximately $4.8 billion) to NBG, consisting of an upfront fee of KRW 1.5 billion (approximately $1.1 million), and KRW 68.5 billion (approximately $50.7 million) contingent upon the achievement of specified development, regulatory and commercial milestones. Scilex Bio is also required to pay royalties equal to 5% of net sales of licensed products, payable quarterly until the expiration of the last-to-expire licensed patent. Aggregate payments to NBG are capped at KRW 6.5 trillion (approximately $4.8 billion). As of June 30, 2025, only the first tranche of the upfront fee (KRW 1.5 billion or approximately $1.1 million) had become payable and was recorded as a current liability.
