Exhibit 99.1

Aimmune Therapeutics Announces First Quarter 2019 Financial Results and Provides Operational Highlights

• Potential FDA approval of AR101 for peanut allergy expected by late January 2020; Company on target to be launch-ready in Q4 2019

• Submission of marketing application for AR101 in Europe on track for mid-2019, following positive topline results of ARTEMIS European Phase 3 trial

• Initiation of AR201 phase 2 trial in egg allergy expected in mid-2019

• Strong balance sheet expected to fund commercialization of AR101 in the U.S. and Europe and development of pipeline

• Webcast and conference call today at 4:30 p.m. ET

BRISBANE, California - May 8, 2019 – Aimmune Therapeutics, Inc. (Nasdaq: AIMT), a biopharmaceutical company developing treatments for life-threatening food allergies, today announced financial results for the quarter ended March 31, 2019. For the quarter ended March 31, 2019, net loss was $54.3 million and cash, cash equivalents, and investments totaled $296.3 million on March 31, 2019.

“We are well on track to introduce AR101 as potentially the first-ever approved treatment for peanut allergy, a significant milestone for our Company, the allergist community, and the millions of people who live with the daily risk of serious reactions to accidental peanut exposure,” said Jayson Dallas, M.D., President and CEO of Aimmune Therapeutics. “The FDA’s acceptance of our BLA was a key step forward and now we continue to work with the FDA to facilitate an expeditious review. In parallel, in the U.S., we are continuing our medical education through our MSL Team and are fully ramping up our commercial efforts and scaling our organization to be launch-ready by Q4 this year. Recent market research has provided additional focus to this effort.  For example, we have found that the approximately 30 percent of allergists who are most eager and ready to offer AR101 to their patients, if approved, today see approximately 70 percent of peanut allergic patients.”

Dr. Dallas added: “We also continue to advance efforts toward submitting a marketing authorization application for AR101 to the European Medicines Agency in mid-2019, following our positive ARTEMIS European phase 3 study.  We are excited to present the full ARTEMIS results at EAACI in early June.  In addition, we expect to initiate a phase 2 trial of AR201 in egg allergy in mid-2019. Moreover, we remain in a strong financial position to commercialize AR101 and advance our pipeline programs.”

AR101 Highlights

• Biologics License Application (BLA) for AR101 was accepted for review by the U.S. Food and Drug Administration (FDA). In March 2019, the FDA accepted for review the BLA for AR101 for the treatment of peanut allergy in children and adolescents ages 4 to 17, which Aimmune had submitted to the agency in December 2018. The FDA informed Aimmune that the BLA will be reviewed under a 12-month target review period, as measured from the January 2019

start date. Review of the BLA may therefore take until late January 2020. The FDA expects to convene an advisory committee meeting to discuss the application.

• Positive phase 3 ARTEMIS topline data announced; submission of marketing authorization application (MAA) to European Medicines Agency (EMA) on track. In March 2019, the Company announced that the phase 3 ARTEMIS European clinical trial of AR101 for the treatment of peanut allergy in children and adolescents ages 4 to 17 met its primary efficacy endpoint. Topline data showed the proportion of AR101-treated patients who tolerated a 1,000-mg dose of peanut protein (2,043 mg cumulative) in a blinded exit challenge after approximately nine months of AR101 treatment was significantly higher (p<0.00001) than in the placebo group. The median tolerated dose of peanut protein for AR101-treated patients improved 100-fold, from 10 mg at baseline to 1,000 mg at exit. The trial also greatly exceeded a 15% lower-bound of the 95% confidence interval (CI) of the difference between treatment arms for the primary endpoint. The safety profile and completion rate observed in ARTEMIS were consistent with results seen in previous AR101 clinical trials, and no cases of anaphylaxis or eosinophilic esophagitis (EoE) were observed. Aimmune intends to submit a MAA for AR101 to the EMA in mid-2019. Aimmune also plans to present full results of the ARTEMIS trial in an oral presentation at the European Academy of Allergy and Clinical Immunology (EAACI) Congress on June 2, 2019.

POSEIDON trial and AR101 with adjunctive dupilumab trials ongoing. In December 2018, Aimmune initiated its phase 3 POSEIDON trial to explore the efficacy and safety of AR101 in young peanut-allergic children, ages 1 to 3.  In October 2018, a phase 2 trial of AR101 with adjunctive dupilumab was initiated in peanut-allergic patients. Regeneron is the trial’s sponsor, and Aimmune is supplying AR101 clinical trial material.

AR201 Highlights

• Phase 2 trial initiation on track for mid-2019. Aimmune’s Investigational New Drug (IND) application for AR201 was cleared by the FDA, as previously announced, and the Company remains on track to begin a phase 2 trial in egg allergy in mid-2019.

Upcoming Milestones
Mid 2019	Initiate phase 2 clinical trial of AR201 in egg allergy
Mid 2019	Submit Marketing Authorization Application for AR101 to the European Medicines Agency
Second Half of 2019	Potential FDA Advisory Committee meeting to review AR101 BLA
Jan 2020	Potential FDA approval of AR101 for the treatment of peanut allergy in children and adolescents ages 4 to 17
Q1 2020	Potential U.S. commercial launch of AR101

First Quarter Financial Results

For the quarter ended March 31, 2019, net loss was $54.3 million, compared to net loss of $49.5 million for the comparable period in 2018.

Page 2 of 6

On a per share basis, net loss for the quarter ended March 31, 2019, was $0.87, compared to net loss per share of $0.92 for the comparable period in 2018. The weighted average shares outstanding for the quarter ended March 31, 2019, were 62.0 million, compared 53.6 million shares for the comparable period in 2018.

Research and development expenses for the quarter ended March 31, 2019, were $31.3 million, compared to $33.4 million for the comparable period in 2018. The decrease was primarily due to lower costs from the progression of certain AR101 clinical trials offset by higher contract manufacturing costs to support clinical development and regulatory activities.

General and administrative expenses for the quarter ended March 31, 2019, were $23.7 million, compared to $16.7 million for the comparable period in 2018. The increase was primarily due to additional employee-related costs and external professional services as Aimmune continued to build its infrastructure to support the development and potential commercialization of AR101.

Cash, cash equivalents, and investments totaled $296.3 million on March 31, 2019, compared to $303.9 million on December 31, 2018. The decrease primarily reflects net cash used in operating activities of $45.8 million partially offset by cash provided by financing activities, including net borrowings from our debt issuance in January 2019 of $36.1 million.

About Aimmune Therapeutics

Aimmune Therapeutics, Inc., is a biopharmaceutical company developing oral treatments for life-threatening food allergies. The company’s Characterized Oral Desensitization ImmunoTherapy (CODIT™) approach is intended to provide meaningful levels of protection against allergic reactions resulting from exposure to food allergens by desensitizing patients with defined, precise amounts of key allergens. Aimmune’s first investigational biologic product, AR101, is being developed as a treatment to reduce the frequency and severity of adverse events following exposure to peanut. The BLA for AR101 is under review by the U.S. FDA, which in 2015 granted AR101 Breakthrough Therapy Designation for the desensitization of peanut-allergic patients 4 to 17 years of age. Aimmune expects to file for marketing approval of AR101 in Europe in mid-2019. Aimmune has filed an IND application for its second product, AR201 for the treatment of egg allergy, and intends to start a randomized phase 2 clinical trial in mid-2019.
