XOMA Announces Proposed Rights Offering

• Rights Offering will be available to all shareholders of record on November 29, 2019
  
• $22 million to be raised; fully backstopped

EMERYVILLE, Calif., Nov. 19, 2019 (GLOBE NEWSWIRE) -- XOMA Corporation (Nasdaq: XOMA) (“XOMA” or the “Company”) today announced its intent to commence a rights offering pursuant to which the Company would raise approximately $22 million through the distribution of subscription rights to holders of its common stock (“Common Stock”), Series X preferred stock (“Series X Preferred”) and Series Y preferred stock (“Series Y Preferred”), which will entitle the holders to purchase shares of XOMA’s Common Stock at $22.00 per share (the “Rights Offering”). The Rights Offering will be fully backstopped by BVF Partners L.P., the Company's largest stockholder, or its assignee/transferee, which has agreed to purchase at a minimum its as-converted pro rata share of the offering amount, plus an additional amount of securities that are not subscribed for by other purchasers in the Rights Offering for a total of up to $22 million.

Under the proposed Rights Offering, the Company plans to distribute non-transferable subscription rights to purchase a portion of a share of Common Stock for each share of Common Stock outstanding and for each share of Common Stock issuable upon conversion of the Company’s outstanding shares of Series X Preferred and Series Y Preferred, at a subscription price per share of $22.00, to its stockholders of record as of the close of business on November 29, 2019 (the “Record Date”).  The subscription rights will be exercisable for an aggregate of 1,000,000 shares of Common Stock, with participation to be allocated among holders of its Common Stock, Series X Preferred and Series Y Preferred on a pro rata basis (assuming full conversion of the Series X Preferred and Series Y Preferred into shares of Common Stock), subject to the aggregate offering threshold and ownership limitations.  The subscription rights are non-transferable and may be exercised only during the anticipated subscription period of Monday, December 2, 2019, through 5:00 PM EDT on Wednesday, December 18, 2019, unless extended.  Any participant in the Rights Offering that, by exercise of its subscription right would become a holder of greater than 9.9% of the outstanding number of shares of Common Stock of the Company following the Rights Offering may elect to instead purchase Series Z Preferred Stock (“Series Z Preferred”) of the Company.  The Company intends to sell the Series Z Preferred at $22,000 per share, and any such holder so electing would have a right to purchase one one-thousandth of a share of Series Z Preferred for each share of Common Stock it had a right to purchase under the subscription rights.  Each share of Series Z Preferred will, subject to certain limitations, be convertible into 1,000 shares of Common Stock at the election of the holder. The Series Z Preferred will generally have no voting rights, except as required by law, and will participate pari passu, on an as-converted basis, with any distribution of proceeds to holders of Common Stock in the event of the Company’s liquidation, dissolution or winding up.

The Rights Offering will be made pursuant to the Company’s effective shelf registration statement on file with the Securities and Exchange Commission and only by means of a prospectus supplement and accompanying prospectus.  The Company expects to mail subscription certificates evidencing the subscription rights and a copy of the prospectus supplement and accompanying prospectus for the Rights Offering shortly following the Record Date.

This press release is not intended to and does not constitute an offer to sell or the solicitation of an offer to subscribe for or buy or an invitation to purchase or subscribe for any securities in any jurisdiction, nor shall there be any sale, issuance or transfer of securities in any jurisdiction in contravention of applicable law.  No offer of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act of 1933, as amended.

BVF Partners L.P., the Company's largest shareholder, currently owning approximately 20.5% of the Company’s outstanding Common Stock (and 53.6% on an as-converted basis), will backstop the Rights Offering and has agreed to purchase up to $22 million of Common Stock  at a subscription price per share of $22.00, subject to approval by Nasdaq, or Series Z Preferred at a price of $22,000 per share in a private placement promptly at the conclusion of the Rights Offering, with the dollar amount to be purchased in such private placement reduced by the dollar amount sold by the Company (including to BVF Partners L.P., and its affiliates) in the Rights Offering.
