Second Quarter and Year-to-Date 2016 Financial Results

For the second quarter ended June 30, 2016, Lion reported research and development expenses of $4.5 million, compared to $4.1 million for the same period in 2015. Year-to-date June 30, 2016 research and development expenses were $8.7 million compared to $6.8 million for the first six months of 2015. The increase in research and development spending in 2016 is due, in part, to the ongoing Phase 2 study for LN-144 and an increase in hiring at the Company's Tampa, Florida research and development facility.

General and administrative expenses increased to $7.3 million for the quarter ended June 30, 2016, compared to $2.4 million for the same period in 2015. Year-to-date June 30, 2016 general and administrative expenses were $10.1 million compared to $4.9 million for the same period in 2015. The increase in general and administrative expenses for 2016 is primarily due to the hiring of new employees along with severance and $3.5 million in non-cash stock compensation charges associated with the Company's former Chief Executive Officer.

Excluding non-cash stock compensation expense, the Company incurred approximately $11.6 million in costs on general and administrative and research and development activities for the six months ended June 30, 2016. After these expenditures and the net proceeds received from the $100 million private placement, the Company held $191.6 million in cash and short-term investments as of June 30, 2016, compared to $103.7 million as of December 31, 2015.

2016 Cash Expectations

Lion anticipates that it will now invest between $35 million and $40 million in its research, development and operations for the 2016 calendar year, resulting in approximately $23 million to $28 million in additional spending for the remainder of 2016.
