First Quarter 2014 Financial Results and Guidance

Prothena reported net income of $17.9 million for the first quarter of 2014 as compared to a net loss of $9.0 million for the first quarter of 2013. Net income per share for the first quarter of 2014 was $0.78 on a diluted basis as compared to a net loss per share of $0.51 for the first quarter of 2013.

Prothena reported total revenue of $32.2 million in the first quarter of 2014 as compared to total revenue of $0.2 million for the first quarter of 2013. The increase was primarily due to $32.1 million in collaboration revenue recognized in relation to the PRX002 collaboration with Roche in the current quarter.

Research and development (R&D) expenses totaled $9.3 million for the first quarter of 2014 as compared to $6.0 million for the first quarter of 2013. The increase in R&D expenses was primarily due to increased external expenses, related to drug development and product manufacturing, higher personnel costs including share-based compensation expense. R&D expenses included non-cash share-based compensation expense of $0.5 million for the first quarter of 2014 as compared to $0.1 million of the first quarter of 2013.

General and administrative (G&A) expenses totaled $4.9 million for the first quarter of 2014 as compared to $3.2 million for the first quarter of 2013. The increase in G&A expenses was primarily due to increases in personnel costs including share based compensation and higher external legal fees. G&A expenses included non-cash share-based compensation expense of $0.9 million for the first quarter of 2014 as compared to $0.3 million for the first quarter of 2013.

Total non-cash share-based compensation expense for the first quarter of 2014 was $1.3 million compared to $0.3 million for the first quarter of 2013.

As of March 31, 2014, Prothena had $195.1 million in cash and cash equivalents, no outstanding debt and 21.9 million ordinary shares outstanding.

As previously announced, the Company expects a net cash burn of $7 to $12 million for 2014, ending the year with approximately $167 million in cash (mid-point). The 2014 net cash burn is primarily driven by an estimated net loss of $13 to $18 million, which includes an estimated $6 million of non-cash share-based compensation expense. The Company intends to use the anticipated 2014 spend primarily to progress clinical development programs related to NEOD001 and PRX002, manufacturing and IND enabling study costs related to PRX003 and costs related to the further advancement of its discovery programs.
