Qualcomm Announces Expiration of its Private Exchange Offers for Four Series of Notes Open to Certain Investors

SAN DIEGO – May 29, 2018 – Qualcomm Incorporated (NASDAQ: QCOM) announced today the expiration of its four separate private offers to exchange (the “Exchange Offers”), any and all of the outstanding notes listed in the table below, which have a special mandatory redemption (“SMR”) date of June 1, 2018 (collectively, the “Old Notes”), in exchange for four new series of Qualcomm’s senior notes which have an SMR provision date of November 1, 2018 (the “New Notes”) and cash, on the terms and subject to the conditions set forth in the Offering Memorandum dated May 21, 2018 (the “Offering Memorandum” and, together with the eligibility letter, the Canadian holder form and the notice of guaranteed delivery, the “Exchange Offer Documents”).

The Exchange Offers expired at 5:00 p.m., New York City time, on May 25, 2018 (the “Exchange Offer Expiration Date”). The “Exchange Offer Settlement Date” will be promptly following the Exchange Offer Expiration Date and is expected to be May 31, 2018. On the terms and subject to the conditions set forth in the Offering Memorandum, the table below provides the aggregate principal amount of each series of Old Notes validly tendered and not validly withdrawn at or prior to the Exchange Offer Expiration Date and the aggregate principal amount of each series of Old Notes that Qualcomm expects to accept on the Exchange Offer Settlement Date in connection with the Exchange Offers.

Based on the amount of Old Notes tendered in the Exchange Offers and in accordance with the terms of the Exchange Offers, Qualcomm expects to accept, on the Exchange Offer Settlement Date, all of the Old Notes validly tendered and not validly withdrawn, other than the 2.100% Notes due 2020. Upon the terms and subject to the conditions set forth in the Exchange Offer Documents, Exchange Offer Eligible Holders (as defined below) who (i) validly tendered and who did not validly withdraw Old Notes at or prior to the Exchange Offer Expiration Date or (ii) delivered a properly completed and duly executed notice of guaranteed delivery and all other required documents at or prior to the Exchange Offer Expiration Date and who tender their Old Notes at or prior to 5:00 p.m., New York City time, on May 30, 2018 pursuant to guaranteed delivery procedures, and whose Old Notes are accepted for exchange by Qualcomm, will receive the applicable Total Consideration (as defined in the Offering Memorandum). Exchange Offer Eligible Holders are required to tender the applicable minimum denominations in order to receive the applicable Total Consideration.

Upon the terms and subject to the conditions set forth in the Offering Memorandum, on the Exchange Offer Settlement Date, Qualcomm expects to deliver an aggregate principal amount of (i) $52,338,000 of Floating Rate Notes due 2019; (ii) $14,506,000 of Floating Rate Notes due 2020; and (iii) $56,205,000 of 1.850% Notes due 2019, in each case for the respective series of Old Notes validly tendered and accepted by Qualcomm, plus a cash fee of $2.50 per $1,000 principal amount of the Old Notes validly tendered and accepted by Qualcomm.

The amount of outstanding 2.100% Notes due 2020 validly tendered and not validly withdrawn as of the Exchange Offer Expiration Date, as reflected in the table above, was not sufficient to meet the minimum condition and consequently no 2.100% Notes due 2020 will be accepted for exchange.

Qualcomm will not receive any cash proceeds from the Exchange Offers. The actual aggregate principal amounts of New Notes that will be issued on the Exchange Offer Settlement Date are subject to change based on deliveries under the guaranteed delivery procedures and final validation of tenders.

Qualcomm will deliver New Notes in exchange for Old Notes accepted for exchange in the Exchange Offers and pay the cash consideration on the Exchange Offer Settlement Date. No accrued but unpaid interest will be paid on the Old Notes in connection with the Exchange Offers. However, interest on each New Note will accrue from and include the most recent interest payment date of the tendered Old Note.

The Exchange Offers were only made, the New Notes were only offered and will only be issued, and copies of the Offering Memorandum were only made available, to a holder of Old Notes who has certified its status as either (a) a “qualified institutional buyer” as defined in Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”) or (b) (i) a person who is not a “U.S. person” as defined under Regulation S under the Securities Act, or a dealer or other professional fiduciary organized, incorporated or (if an individual) residing in the United States holding a discretionary account or similar account (other than an estate or trust) for the benefit or account of a non-“U.S. person”, (ii) if located or resident in the European Economic Area, that they are persons other than “retail investors” (for these purposes, a retail investor means a person who is one (or more) of: (x) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (y) a customer within the meaning of Directive 2002/92/EC (as amended, the “Insurance Mediation Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (z) not a qualified investor as defined in Directive 2003/71/EC (as amended, the “Prospectus Directive”)) and (iii) if located or resident in any province or territory of Canada, is not an individual and is an “accredited investor” as such term is defined in National Instrument 45-106 of the Canadian Securities Administrators or section 73.3(1) of the Securities Act (Ontario), and in each case, is also a “permitted client” as defined in National Instrument 31- 103 of the Canadian Securities Administrators (“Canadian Eligible Holders”). Qualcomm refers to holders of Old Notes who certified to Qualcomm that they were eligible to participate in the Exchange Offers pursuant to at least one of the foregoing conditions as “Exchange Offer Eligible Holders”.

Only Exchange Offer Eligible Holders who have confirmed they are Exchange Offer Eligible Holders via the eligibility letter were authorized to receive or review the Exchange Offer Documents or to participate in the Exchange Offers. For Canadian Eligible Holders, such participation was also conditioned upon the receipt of the Canadian holder form. There was no separate letter of transmittal in connection with the Offering Memorandum.

The New Notes have not been registered under the Securities Act or any state securities laws. Therefore, the New Notes may

not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and any applicable state securities laws.
