Financial Performance

Revenues were $3.9 million for the fourth quarter of 2016 and $50.7 million for the full year 2016, compared to $34.4 million and $73.0 million, respectively, for the same periods in 2015. The decrease in revenue for the fourth quarter of 2016 was primarily due to recognition of milestones and a portion of upfront fees under Aduro’s research and license agreements with Janssen in 2015. The decrease in revenue for the full year 2016 was also due to recognition of milestones and a portion of upfront fees under the Janssen agreements in 2015 partially offset by a $35.0 million payment recognized in 2016 upon achievement of a milestone under Aduro’s collaboration and license agreement with Novartis.

Research and development expenses were $20.9 million for the fourth quarter of 2016 and $87.7 million for the full year 2016, compared to $22.7 million and $58.6 million, respectively, for the same periods in 2015. The decrease in research and development expenses for the fourth quarter of 2016 was primarily due to higher licensing fees paid in 2015. The increase in research and development expenses for the full year 2016 was primarily due to contract manufacturing and research expenses associated with our ongoing studies and increased personnel and facility-related costs.

General and administrative expenses were $8.0 million for the fourth quarter of 2016 and $34.3 million for the full year 2016, compared to $8.8 million and $27.8 million, respectively, for the same periods in 2015. The decrease in general and administrative expenses for the fourth quarter of 2016 was primarily due to lower professional fees in 2016. The increase in general and administrative expenses for the full year 2016 was primarily due to higher personnel and facility related costs. There was no loss from remeasurement of fair value of warrants during the fourth quarter or full year 2016. There was a $26.1 million loss from remeasurement of fair value of warrants in the full year 2015 that occurred in April 2015 when certain outstanding warrants were no longer subject to future remeasurement.

Provision for income taxes was $5.1 million for the fourth quarter of 2016 and $21.5 million for the full year 2016. There was no provision for income taxes for the comparable periods in 2015. The income tax expense recorded for the fourth quarter and full year 2016 was primarily related to current and deferred federal income taxes.
