On November 10, 2022, Rubric Capital Management LP issued a press release announcing that it sent a letter to the board of directors of Chimerix, Inc. setting forth certain of its views on the Company. Rubric Capital Management stated that it has had and anticipate having further discussions with officers and directors of the Company in connection with its investment in the Company. In the letter, Rubric Capital Management stated that the Company is on the wrong path and is being frivolous with shareholder value.

Rubric Capital Management added that continuing to invest in ONC201 despite the likely need for an expensive phase 3 trial is not an appropriate course of action for a Company of this size and with such an onerous cost of capital. Rubric Capital Management expressed its view that the Board must simultaneously begin a winddown process to maximize liquidation value available to shareholders and commence a strategic alternatives process for ONC201.
