“We have come out of the first quarter of 2018 in a strong position with positive Phase 3 results for AR101, which have been met with widespread enthusiasm across the food allergy community,” said Stephen Dilly, MBBS, Ph.D., CEO of Aimmune. “Throughout 2018, we expect to present additional data from the AR101 Phase 3 program and to complete clinical and manufacturing activities in support of BLA and MAA filings. In parallel, we are ramping up precommercial activities for a potential commercial launch of AR101 in the United States in 2019. We are in a strong financial position following our successful public offering completed in the first quarter and continue to own world-wide rights to AR101 and all our other CODIT product candidates. We look forward to an event-rich year ahead as we continue to lead the way in developing therapies for life-threatening food allergies.”

First Quarter Financial Results

For the quarter ended March 31, 2018, net loss was $49.5 million, compared to net loss of $25.9 million for the comparable period of 2017.

On a per share basis, net loss for the quarter ended March 31, 2018, was $0.92, compared to net loss per share of $0.52 for the comparable period of 2017. In the first quarter of 2018, the Company completed an underwritten public offering for the sale and issuance of an aggregate of 6,325,000 shares of common stock, which includes the exercise in full of the underwriters’ option to purchase an additional 825,000 shares of common stock.

Research and development expenses for the quarter ended March 31, 2018, were $33.4 million, compared to $17.4 million for the comparable period in 2017. The increase was primarily due to the progression of the AR101 program, which includes the RAMSES, ARC008, ARTEMIS and ARC011 trials that commenced in 2017, and higher contract manufacturing costs to support clinical development.

General and administrative expenses for the quarter ended March 31, 2018, were $16.7 million, compared to $8.9 million for the comparable period in 2017. The increase was primarily due to additional employee-related costs and external professional services as Aimmune continues to build its infrastructure to support the development and potential commercialization of AR101. Stock-based compensation expense also increased primarily due to the January 2018 issuance of restricted common stock in connection with the expansion and extension of our long-term commercial supply agreement with Golden Peanut Company and modification of certain executives’ stock option arrangements.

Cash, cash equivalents, and investments totaled $331.7 million at March 31, 2018, compared to $182.4 million at December 31, 2017. The increase primarily reflects net cash proceeds of $189.5 million received as of March 31, 2018 from an underwritten public offering, partially off-

set by net cash used in operating activities of $39.8 million and purchase of property and equipment of $2.4 million in the first quarter of 2018.
