FINANCIAL RESULTS FOR THE YEAR ENDED DECEMBER 31, 2014

Research and development expense for the 2014 Period increased 5% to $2.9 million compared to $2.7 million for the 2013 Period. The primary reasons for this change are related to   increased patent legal fees of $286,111 associated with licenses. Salaries and compensation related expense increased by $252,350 due to hiring over the course of the year. Administrative and allocated expense related to the expansion of the lab during 2014 increased by $206,417. These increases were offset by $702,271 in pre-manufacturing costs as we began manufacturing clinical trial batches.

Clinical and regulatory expense for the 2014 Period increased to $5.3 million compared to $1.4 million for the 2013 Period. The $3.9 million increase from the 2013 Period to the 2014 Period was primarily from an increase of $2.0 million in clinical trial execution, $1.2 million in payments to investigators, specimen management and other clinical trial expenses, and $395,851 in drug development and manufacturing related to our clinical trials.

General and administrative expense for the 2014 Period increased to $4.0 million compared to $2.4 million for the 2013 Period. The $1.6 million increase from the 2013 Period to the 2014 Period is primarily attributable to an increase in personnel costs of $786,595, including non-cash, stock-based compensation of $277,473.  

Total operating expenses for the 2014 period increased to $12.2 million compared to $6.6 million for the 2013 period.  Operating expenses are primarily comprised of research and development, clinical and regulatory, and general and administrative expenses.  

The Company reported a net loss attributable to common stockholders of $11.8 million, or ($1.83) per basic and diluted share for the year ended December 31, 2014.  This compares to a net loss of $9.1 million, or ($2.42) per basic and diluted share for the year ended December 31, 2013, (the “2013 Period”).

As of December 31, 2014, cash, cash equivalents and short-term investments totaled $14.4 million.  On March 16, 2015, the Company closed on a public offering of 1,886,000 shares of common stock, which includes 246,000 shares to cover over-allotments, which the underwriters exercised in full. This offering generated gross proceeds to Heat of approximately $12.3 million, before deducting underwriting discounts and commissions and other estimated offering expenses payable by the Company.
