Aimmune appreciates the continued strong collaboration with Nestlé Health Science dating back to 2016 through their support as a shareholder and board member, as well as through their consumer/nutrition strength and experience. Their extensive capabilities and global reach, as well as their alignment with our vision of pioneering treatments and solutions for food allergies, are a strong fit for our company.”

“This transaction brings together Nestlé’s nutritional science leadership with one of the most innovative companies in food allergy treatment,” said Nestlé Health Science CEO Greg Behar. “Together, we will be able to create a world leader in food allergy prevention and treatment and offer a wide range of solutions that can transform the lives of people around the world living with food allergies.”

The transaction is expected to close in the fourth quarter of 2020, pending the satisfaction of all conditions to the completion of the tender offer. Until that time, Aimmune will continue to operate as a separate and independent company.

Transaction Details

Under the terms of the merger agreement, Nestlé S.A.’s wholly-owned subsidiary, Société des Produits Nestlé S.A. (SPN), will commence a cash tender offer to acquire all outstanding shares of Aimmune common stock that are not already owned by NHSc for $34.50 per share in cash, and Aimmune agreed to file a recommendation statement containing the unanimous recommendation of the independent members of the Aimmune board that Aimmune stockholders tender their shares to SPN. Following the completion of the tender offer, Nestlé expects to promptly consummate a merger of Aimmune with a subsidiary of SPN, in which shares of Aimmune that have not been tendered in the tender offer will be acquired by SPN and converted into the right to receive the same cash price per share as paid in the tender offer.

The closing of the tender offer is subject to customary closing conditions, including the tender of a majority of outstanding Aimmune shares on a fully diluted basis which shall include the shares of Aimmune common stock currently held by Nestlé and its affiliates and the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act and antitrust approvals in Germany. The merger agreement includes customary termination provisions for both Aimmune and Nestlé.

INDICATION

PALFORZIA is an oral immunotherapy indicated for the mitigation of allergic reactions, including anaphylaxis, that may occur with accidental exposure to peanut. PALFORZIA is approved for use in patients with a confirmed diagnosis of peanut allergy. Initial Dose Escalation may be administered to patients aged 4 through 17 years. Up-Dosing and Maintenance may be continued in patients 4 years of age and older.

PALFORZIA is to be used in conjunction with a peanut-avoidant diet.

Limitations of Use: Not indicated for the emergency treatment of allergic reactions, including anaphylaxis.

IMPORTANT SAFETY INFORMATION

Boxed WARNING:

PALFORZIA can cause anaphylaxis, which may be life threatening and can occur at any time during PALFORZIA therapy.

Prescribe injectable epinephrine, instruct and train patients on its appropriate use, and instruct patients to seek immediate medical care upon its use.

Do not administer PALFORZIA to patients with uncontrolled asthma.

Dose modifications may be necessary following an anaphylactic reaction.

Observe patients during and after administration of the Initial Dose Escalation and the first dose of each Up-Dosing level, for at least 60 minutes.

Page 3 of 6

PALFORZIA is available only through a restricted program called the PALFORZIA REMS.

CONTRAINDICATIONS

PALFORZIA is contraindicated in patients with uncontrolled asthma, or with a history of eosinophilic esophagitis and other eosinophilic gastrointestinal disease.

WARNINGS AND PRECAUTIONS

Anaphylaxis

PALFORZIA can cause anaphylaxis, which may be life threatening. PALFORZIA is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the PALFORZIA REMS because of the risk of anaphylaxis. Only prescribers, healthcare settings, pharmacies, and patients certified and enrolled in the REMS Program can prescribe, receive, dispense or administer PALFORZIA.

Anaphylaxis has been reported during all phases of PALFORZIA dosing, including Maintenance and in subjects who have undergone recommended Up-Dosing and dose modification procedures.

Do not initiate PALFORZIA treatment in a patient who has had severe or life-threatening anaphylaxis within the previous 60 days. PALFORZIA may not be suitable for patients with certain medical conditions that may reduce the ability to survive anaphylaxis, including but not limited to markedly compromised lung function, severe mast cell disorder, or cardiovascular disease. In addition, PALFORZIA may not be suitable for patients taking medications that can inhibit or potentiate the effects of epinephrine.

All Initial Dose Escalation doses and the first dose of each Up-Dosing level must be administered in a certified health care setting.

Patients may be more likely to experience allergic reactions following PALFORZIA administration in the presence of cofactors such as exercise, hot water exposure, intercurrent illness (e.g., viral infection), or fasting. Other potential cofactors may include menstruation, sleep deprivation, nonsteroidal anti-inflammatory drug use, or uncontrolled asthma. Patients should be proactively counseled about the potential for the increased risk of anaphylaxis in the presence of these cofactors. If possible, adjust the time of dosing to avoid these cofactors. If it is not possible to avoid these cofactors, consider withholding PALFORZIA temporarily.

Asthma

Uncontrolled asthma is a risk factor for a serious outcome, including death, in anaphylaxis. Ensure patients with asthma have their asthma under control prior to initiation of PALFORZIA.

PALFORZIA should be temporarily withheld if the patient is experiencing an acute asthma exacerbation. Following resolution of the exacerbation, resumption of PALFORZIA should be undertaken cautiously. Re-evaluate patients who have recurrent asthma exacerbations and consider discontinuation of PALFORZIA.

Eosinophilic Gastrointestinal Disease

Discontinue PALFORZIA and consider a diagnosis of eosinophilic esophagitis in patients who experience severe or persistent gastrointestinal symptoms, including dysphagia, vomiting, nausea, gastroesophageal reflux, chest pain, or abdominal pain.

Gastrointestinal Adverse Reactions

Gastrointestinal adverse reactions were commonly reported in PALFORZIA-treated subjects, and dose modification should be considered for patients who report these reactions. For severe or persistent gastrointestinal symptoms consider a diagnosis of eosinophilic esophagitis.

ADVERSE REACTIONS

The most common adverse events reported in subjects treated with PALFORZIA (incidence ³ 5% and ³ 5% than placebo) are abdominal pain, vomiting, nausea, oral pruritus, oral paresthesia, throat irritation, cough, rhinorrhea, sneezing, throat tightness, wheezing, dyspnea, pruritus, urticaria, anaphylactic reaction, and ear pruritus.
