4550 Towne Centre Court
San Diego, CA 92121
La Jolla Pharmaceutical Company is a corporation dedicated to the development and commercialization of innovative therapies that improve outcomes in patients suffering from life-threatening diseases.
Information Regarding Legal Proceedings
To the knowledge of the Reporting Person, it has not been convicted in a criminal proceeding or been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which such party was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.
Citizenship
La Jolla Pharmaceutical Company is a California corporation.
Item 3. | Source and Amount of Funds or Other Consideration |
The Reporting Person has expended an aggregate of approximately $2.7 million to purchase 1,085,000shares of the Issuer’s Common Stock. Such purchases were effected through the open-market. The Reporting Person used its own funds for the purchases, none of which were borrowed or otherwise obtained from any other source for the purpose of acquiring, holding, trading or voting the securities.
Item 4. | Purpose of Transaction |
The Reporting Person is engaged in the pharmaceutical business. The Issuer, a biopharmaceutical company, has received multiple bids in support of an acquisition of the Issuer. On each of May 6, 2020 and May 11, 2020, the Reporting Person sent the Issuer a letter offering to purchase the Issuer at a premium to the purchase price the Issuer had accepted from another prospective purchaser. Before the Reporting Person was able to fully engage with the Issuer on the Reporting Person’s offer, the Issuer entered into an acquisition agreement with another prospective purchaser at a purchase price higher than that offered by the Reporting Person. The Reporting Person sent the Issuer another bid letter on June 19, 2020, once more offering to acquire the Issuer at a premium to the then-current purchase price. The Reporting Person has purchased shares of Common Stock of the Issuer for the purpose of advancing the acquisition proposal it delivered to the Issuer on June 19, 2020. At this time, the Reporting Person does not intend to obtain control of the Issuer through a hostile tender offer or proxy process; instead, the Reporting Person continues to offer and pursue a competing bid for the acquisition of the Issuer.
The Reporting Person may take such actions in the future with respect to its investment in the Issuer’s Common Stock as it deems advisable, including, without limitation, purchasing additional shares, selling shares, entering into hedging transactions with respect to the shares and/or otherwise changing its intention with respect to the matters referred to in Item 4 of Schedule 13D. Such actions will depend on various factors including, without limitation, the Issuer’s response to the Reporting Person’s bids, the Issuer’s financial and strategic direction and position, the price performance of the Issuer’s Common Stock, general conditions in the Issuer’s industry, the economy and securities markets, and the availability of other investment opportunities.
