"We entered 2024 with the strongest cash position in the Company's history, several key upcoming clinical and regulatory events, including the potential approvals of Day One's tovorafenib and Zevra Therapeutics' arimoclomol NDAs, and a growing pipeline of asset opportunities."

Financial Results
XOMA recorded total revenues of $1.8 million and $4.8 million for the fourth quarter and full year of 2023, respectively. In 2023, XOMA recognized $2.5 million in milestone payments received from two partners, whereas the Company reported revenues of $6.0 million in 2022, of which $4.0 million were milestone payments received from four partners.

General and administrative ("G&A") expenses were $7.3 million for the fourth quarter and $25.6 million for the full year of 2023. In the fourth quarter and full year of 2022, G&A expenses were $7.6 million and $23.2 million, respectively. The increase of $2.4 million between the two full-year periods was primarily due to a $5.5 million increase in stock-based compensation, partially offset by a $2.1 million decrease in consulting and legal expenses, and a $0.9 million decrease in salaries and related expenses.

In the fourth quarter of 2023, G&A expenses included $2.6 million in non-cash stock-based compensation expense, compared with $1.0 million in the fourth quarter of 2022. For the full year of 2023, G&A expenses included $9.1 million in non-cash stock-based compensation, compared with $3.6 million for the full year of 2022.

XOMA received cash payments of approximately $5.7 million from royalties and milestone payments in the fourth quarter of 2023, as compared to $0.8 million in the comparable period in 2022. During the full year of 2023, the Company received cash payments of approximately $15.5 million from royalties and milestone payments, as compared to $7.2 million in 2022. XOMA's net cash used in operations during the fourth quarter of 2023 was $3.9 million and $18.2 million for the full year, as compared with $3.9 million used during the fourth quarter of 2022 and $12.9 million used for the full year of 2022.

XOMA incurred one-time arbitration settlement costs of $4.1 million in 2023, related to an arbitration proceeding settlement with one of its licensees.

For the year ended December 31, 2023, XOMA recorded $15.8 million in impairment charges, as a result of the discontinuation of operations at Bioasis ($1.6 million) and Organon's decision to terminate its License Agreement for ebopiprant ($14.2 million).

Other income, net was $1.6 million for the full year of 2023 and $0.3 million for the full year of 2022. The increase in other income, net between periods is primarily due to an increase in investment income.

In 2023, net loss for the fourth quarter and year ended December 31, 2023, was $20.1 million and $40.8 million, respectively. In 2022, the net loss for the fourth quarter was $6.0 million and $17.1 million for the full year.

On December 31, 2023, XOMA had cash and cash equivalents of $159.6 million (including $6.3 million in restricted cash). In 2023, XOMA's royalty interests generated cash payments of $7.3 million from Roche related to VABYSMO® sales and $1.7 million from Medexus related to IXINITY® sales. The Company also received a $5.0 million milestone payment from Viracta related to the FDA's acceptance of Day One Pharmaceuticals' NDA for tovorafenib. These cash receipts from royalty and milestone acquisitions reduced XOMA's short-term royalty and commercial payment receivables by $14 million. On October 16, 2023, the Company paid total cash dividends of $1.4 million on the 8.625% Series A Cumulative Perpetual Preferred Stock (Nasdaq: XOMAP) and on the 8.375% Series B Cumulative Perpetual Preferred Stock (Nasdaq: XOMAO). In December 2023, XOMA drew $130.0 million from its royalty-backed loan with certain funds managed by the credit platform of Blue Owl Capital. On December 31, 2022, the Company reported cash of $57.8 million. Based upon the cash flows XOMA expects to receive from VABYSMO®, DSUVIA®, and IXINITY® sales in addition to its current cash position, the Company continues to believe its current cash position will be sufficient to fund XOMA's operations for multiple years.

Subsequent Events
On January 2, 2024, the Company announced a stock repurchase program of up to $50 million through January 2027.

On January 7, 2024, Owen Hughes was appointed as Chief Executive Officer and Jack Wyszomierski was named Chairman of the Board of Directors.

On January 18, 2024, XOMA acquired an economic interest in DSUVIA® (sufentanil sublingual tablet) from Talphera, Inc., for $8 million. DSUVIA® is commercialized by Alora Pharmaceuticals. XOMA will receive 100 percent of all royalties and milestones related to DSUVIA® sales until it receives $20 million. Thereafter, XOMA will receive a 15 percent royalty associated with DSUVIA® commercial sales, a 37.5 percent royalty on DoD purchases and 50 percent of the remaining $116.5 million in potential milestone payments due from Alora Pharmaceuticals.

On February 16, 2024, XOMA announced its intention to acquire Kinnate Biopharma for between $2.3352 and $2.5879 in cash per share plus a contingent value right (CVR). XOMA anticipates it will add approximately $9.5 million to its cash balance at the closing of the acquisition, which is expected to occur in April 2024.

Forward-Looking Statements/Explanatory Notes
Certain statements contained in this press release are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, including statements regarding the timing and amount of potential commercial payments to XOMA and other developments related to VABYSMO® (faricimab-svoa), IXINITY® [coagulation factor IX (recombinant)], DSUVIA® (sufentanil sublingual tablet), tovorafenib, and arimoclomol; the potential out-licensing of ebopiprant to an external partner for further development; the anticipated timings of regulatory filings and approvals related to assets in XOMA's portfolio; the potential of XOMA's portfolio of partnered programs and licensed technologies generating substantial milestone and royalty proceeds over time; and XOMA's cash sufficiency forecast. In some cases, you can identify such forward-looking statements by terminology such as "anticipate," "intend," "believe," "estimate," "plan," "seek," "project," "expect," "may," "will", "would," "could" or "should," the negative of these terms or similar expressions. These forward-looking statements are not a guarantee of XOMA's performance, and you should not place undue reliance on such statements. These statements are based on assumptions that may not prove accurate, and actual results could differ materially from those anticipated due to certain risks inherent in the biotechnology industry, including those related to the fact that our product candidates subject to out-license agreements are still being developed, and our licensees may require substantial funds to continue development which may not be available; we do not know whether there will be, or will continue to be, a viable market for the products in which we have an ownership or royalty interest; if the therapeutic product candidates to which we have a royalty interest do not receive regulatory approval, our third-party licensees will not be able to market them; and the impact to the global economy as a result of the COVID-19 pandemic. Other potential risks to XOMA meeting these expectations are described in more detail in XOMA's most recent filing on Form 10-Q and in other filings with the Securities and Exchange Commission. Consider such risks carefully when considering XOMA's prospects. Any forward-looking statement in this press release represents XOMA's beliefs and assumptions only as of the date of this press release and should not be relied upon as representing its views as of any subsequent date. XOMA disclaims any obligation to update any forward-looking statement, except as required by applicable law.

EXPLANATORY NOTE: Any references to "portfolio" in this press release refer strictly to milestone and/or royalty rights associated with a basket of drug products in development. Any references to "assets" in this press release refer strictly to milestone and/or royalty rights associated with individual drug products in development.

As of the date of this press release, all assets in XOMA's milestone and royalty portfolio, except VABYSMO® (faricimab-svoa), IXINITY® [coagulation factor IX (recombinant)], DSUVIA® (sufentanil sublingual tablet), are investigational compounds.
