Re:	HP Inc. Registration Statement on Form S‑4

Ladies and Gentlemen:

We have acted as counsel to HP Inc., a Delaware corporation (the “Company”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) of a Registration Statement on Form S-4 (the “Registration Statement”) under the Securities Act of 1933, as amended (the “Securities Act”), the prospectus included therein, and the offer to exchange pursuant thereto up to $1,000,000,000 aggregate principal amount of the Company’s outstanding 1.450% notes due 2026 (the “2026 Outstanding Notes”) and up to $1,000,000,000 aggregate principal amount of the Company’s outstanding of 2.650% notes due 2031 (the “2031 Outstanding Notes” and, together with the 2026 Outstanding Notes, the “Outstanding Notes”), for up to $1,000,000,000 aggregate principal amount of its new 1.450% notes due 2026 (the “2026 Exchange Notes”) and $1,000,000,000 aggregate principal amount of its new 2.650% notes due 2031 (the “2031 Exchange Notes” and, together with the 2026 Exchange Notes, the “Exchange Notes;” the Outstanding Notes and the Exchange Notes are together referred to as the “Notes”). The Exchange Notes will be issued pursuant to the Indenture, dated as of June 17, 2020, as supplemented by the First Supplemental Indenture, dated as of June 16, 2021 (the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”).

In arriving at the opinions expressed below, we have examined originals, or copies certified or otherwise identified to our satisfaction as being true and complete copies of the originals, of the Indenture, the form of Notes (the “Note Documents”) and such other documents, corporate records, certificates of officers of the Company and of public officials and other instruments as we have deemed necessary or advisable to enable us to render these opinions. In our examination, we have assumed, without independent investigation, the genuineness of all signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us as copies. As to any facts material to these opinions, we have relied to the extent we deemed appropriate and without independent investigation upon statements and representations of officers and other representatives of the Company and others.
