Exhibit (a)(5)(xi)

Ligand Announces Expiration of Tender Offer for Shares of Pfenex Inc.

SAN DIEGO, Calif. (September 30, 2020) – Ligand Pharmaceuticals Incorporated (NASDAQ: LGND) today announced that its tender offer to purchase any and all issued and outstanding shares of common stock of Pfenex Inc. (NYSE American: PFNX) at an offer price of $12.00 per share in cash, plus one non-transferable contractual contingent value right per share representing the right to receive a contingent payment of $2.00 in cash, if a certain specified milestone is achieved, expired at midnight (New York City time), at the end of the day on Tuesday, September 29, 2020.

The depositary for the tender offer has advised that, as of the expiration of the tender offer, a total of approximately 27,591,554 shares were validly tendered and not withdrawn in the tender offer (including shares delivered through notices of guaranteed delivery), representing approximately 80.3% of Pfenex’s outstanding shares. Ligand’s wholly-owned subsidiary will accept for payment all shares that were validly tendered and not withdrawn prior to expiration of the tender offer, and payment for such shares will be made promptly, in accordance with the terms of the tender offer.

Ligand expects the merger to close on October 1, 2020, with Pfenex becoming a wholly owned subsidiary of Ligand. As a consequence of the merger, each outstanding Pfenex share not tendered and purchased in the offer (other than those as to which holders properly exercise dissenters’ rights and those owned at the commencement of the tender offer by Ligand or its direct and indirect subsidiaries) will be converted into the right to receive the same $12.00 per share in cash, plus one non-transferable contractual contingent value right per share representing the right to receive a contingent payment of $2.00 in cash, if a certain specified milestone is achieved, without interest and less any required withholding taxes, that was offered in the tender offer. Following completion of the merger, Pfenex’s common stock will cease to be traded on the New York Stock Exchange American.
