Item 1.01. Entry into a Material Definitive Agreement.

On September 26, 2018, PetIQ, Inc. (the “Company”), together with certain stockholders of the Company (collectively, the “Selling Stockholders”) entered into an underwriting agreement (the “Underwriting Agreement”) with Jefferies LLC, as representative of the several underwriters named therein (collectively, the “Underwriters”), relating to the public offering of an aggregate 5,750,000 shares of Class A common stock, par value $0.001 per share (the “Common Stock”), at a purchase price per share to the public of $39.00 (the “Offering Price”).

Pursuant to the terms and conditions of the Underwriting Agreement, 2,000,000 shares of Common Stock will be issued and sold by the Company (the “Primary Shares”) and 3,750,000 shares of Common Stock will be sold by the Selling Stockholders (the “Secondary Shares”), including 1,911,964 Class A Shares issuable upon exchange of membership units (the “LLC Interest”) of PetIQ Holdings, LLC (“HoldCo”) with an equal number of shares of the Company’s Class B common stock.

The net proceeds to the Company from the sale of the Primary Shares to be issued and sold by the Company, after deducting underwriting discounts and commissions and estimated offering expenses, will be approximately $73.6 million. The Company intends to use the net proceeds from the offering to purchase 2,000,000 LLC Interests from HoldCo at a price per LLC Interest equal to the public offering price per share of the Common Stock, after deducting underwriting discounts and commissions. The Company intends to cause HoldCo to use the proceeds from the sale of the LLC Interests for working capital and other general corporate purposes. The Company will not receive any of the proceeds from the sale of Secondary Shares by the Selling Stockholders. The offering closed on October 1, 2018.

The Common Stock was offered and sold pursuant to a preliminary prospectus supplement, dated September 24, 2018, a final prospectus supplement, dated September 27, 2018, and a base prospectus, dated September 21, 2018, relating to the Company’s effective shelf registration statement on Form S-3 (File No. 333-227186).

The Underwriting Agreement contains customary representations, warranties and agreements by the Company and the Selling Stockholders, customary conditions to closing, indemnification obligations of the Company, the Selling Stockholders and the Underwriters, including for liabilities under the Securities Act of 1933, as amended, other obligations of the parties and termination provisions.

The 2,000,000 shares to be issued and sold by the Company and the 3,000,000 shares to be sold by the Selling Stockholders are collectively referred to herein as the “Firm Shares”.

Certain of the Selling Stockholders also severally propose to sell to the several Underwriters, subject to the terms and conditions stated herein, up to an additional 750,000 shares of Common Stock (the “Additional Shares”) if and to the extent that the Representative shall have determined to exercise, on behalf of the Underwriters, the right to purchase such shares of Common Stock granted to the Underwriters in Section 3 hereof. The Firm Shares and the Additional Shares are hereinafter collectively referred to as the “Shares.”

On the date hereof, the Company is a holding company which currently holds no material assets and does not engage in any operations. The business of the Company is conducted through PetIQ Holdings, LLC, a Delaware limited liability company (“HoldCo”), of which the Company is the sole managing member, and its subsidiaries, including PetIQ, LLC, an Idaho limited liability company (“OpCo”), of which HoldCo is the sole managing member.

1. Representations and Warranties of the PetIQ Parties. Each PetIQ Party, jointly and severally, represents and warrants to and agrees with each of the Underwriters on the date hereof, on the Time of Sale, the Closing Date (as defined in Section 5) and on the Option Closing Date (as defined in Section 3), if any, that:

(a) The Registration Statement has become effective under the Securities Act; no stop order suspending the effectiveness of the Registration Statement is in effect, and no proceedings for such purpose are pending before or, to the knowledge of the PetIQ Parties, threatened by the Commission. At the time the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 (the “Annual Report”) was filed with the Commission, or, if later, at the time the Registration Statement was originally filed with the Commission, the Company met the then-applicable requirements for use of Form S-3 under the Securities Act. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the Time of Sale Prospectus and the Prospectus, at the time they were or hereafter are filed with the Commission, or became effective under the Exchange Act, as the case may be, complied and will comply in all material respects with the requirements of the Exchange Act.

(b) The Preliminary Prospectus filed as part of the Registration Statement or pursuant to Rule 424 under the Securities Act, when so filed, complied in all material respects with the Securities Act and the rules and regulations thereunder (including, without limitation, Rule 424, 430A and 430B under the Securities Act).

(c) Each preliminary prospectus and the Prospectus when filed complied in all material respects with the Securities Act and, if filed by electronic transmission pursuant to EDGAR, was identical (except as may be permitted by Regulation S-T under the Securities Act) to the copy thereof delivered to the Underwriters for use in connection with the offer and sale of the Shares. Each of the Registration Statement and any post-effective amendment thereto, at the time it became or becomes effective, complied and will comply in all material respects with the Securities Act and did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. As of the Applicable Time, the Time of Sale Prospectus did not, and at the Closing Date and at each applicable Option Closing Date, will not, contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Prospectus, as of its date and at the Closing Date and at each applicable Option Closing Date, will not, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Each Permitted Free Writing Prospectus does not conflict with the information contained in the Registration Statement, the Preliminary Prospectus, the Time of Sale Prospectus or the Prospectus and was accompanied or preceded by the then-most recent Preliminary Prospectus, to the extent required by Rule 433 under the Securities Act. Each road show (as defined in Rule 433 under the Securities Act) presentation that is a “written communication” (as defined in Rule 405 under the Securities Act), when considered together with the Time of Sale Prospectus, does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. The representations and warranties set forth in this Section 1(c) do not apply to statements or omissions in the Registration Statement, the Time of Sale Prospectus, the Preliminary Prospectus, any Permitted Free Writing Prospectus, any road show or the Prospectus or any amendments or supplements (or prospectus wrapper) thereto based upon information relating to any Underwriter furnished to the Company in writing by such Underwriter through Jefferies expressly for use therein, it being agreed that the only information furnished by the Underwriters to the Company expressly for use therein are the statements contained in the first sentence of paragraph 3, paragraph 5 and the paragraphs under “—Stabilization” of the “Underwriting” section of the Time of Sale Prospectus and Prospectus (collectively, the “Underwriter Information”).

On the day, if any, that Additional Shares are to be purchased (the “Option Closing Date”), each Underwriter agrees, severally and not jointly, to purchase the number of Additional Shares (subject to such adjustments to eliminate fractional shares as Jefferies may determine) that bears the same proportion to the total number of Additional Shares to be purchased on such Option Closing Date as the number of Firm Shares set forth in Schedule I hereto opposite the name of such Underwriter bears to the total number of Firm Shares.

4. Terms of Public Offering. It is understood that the Underwriters propose to offer the Shares for sale to the public initially at $39.00 per share (the “Public Offering Price”) and to certain dealers selected by Jefferies at a price that represents a concession not in excess of $1.1115 per share under the Public Offering Price, as set forth in the Prospectus.

5. Payment and Delivery. Payment for the Firm Shares to be sold by (i) the Company shall be made to the Company and (ii) by the Selling Stockholders shall be made to the Custodian in Federal or other funds immediately available in Chicago against delivery of such Firm Shares by the Company and by the Custodian for the respective accounts of the several Underwriters at 10:00 a.m., Central Time, on October 1, 2018, or at such other time on the same or such other date, not later than the fifth business day thereafter, as shall be designated in writing by Jefferies. The time and date of such payment are hereinafter referred to as the “Closing Date.”

Payment for any Additional Shares to be sold by the Selling Stockholders shall be made to the Custodian in Federal or other funds immediately available in Chicago against delivery of such Additional Shares by the Custodian for the respective accounts of the several Underwriters at 10:00 a.m., Central Time, on the date specified in the corresponding notice described in Section 3 or at such other time on the same or on such other date, as shall be designated in writing by Jefferies.

The Firm Shares and Additional Shares shall be registered in such names and in such denominations as Jefferies shall request in writing not later than one full business day prior to the Closing Date or the applicable Option Closing Date, as the case may be. The Firm Shares and Additional Shares shall be delivered to Jefferies on the Closing Date or an Option Closing Date, as the case may be, for the respective accounts of the several Underwriters, with any transfer taxes payable in connection with the transfer of the Shares to the Underwriters duly paid, against payment of the Purchase Price therefor. Delivery of the Shares shall be made through the facilities of DTC for the accounts of the Underwriters, unless Jefferies shall otherwise instruct. The certificates for the Shares, if any, will be made available for inspection and packaging by Jefferies at the office of DTC or its designated custodian not later than 12:00 p.m., Central Time, on the business day prior to the Closing Date or Optional Closing Date, as the case may be.

7. Covenants of the PetIQ Parties. Each of the PetIQ Parties, jointly and severally, covenants with each Underwriter as follows:

(a) The Company will furnish to Jefferies, without charge, a conformed copy of the Registration Statement (including exhibits thereto) and for delivery to each other Underwriter a conformed copy of the Registration Statement (without exhibits thereto) and furnish to Jefferies in Chicago, Illinois, without charge, prior to 10:00 a.m. Central Time on the business day next succeeding the date of this Agreement and during the period mentioned in Section 7(g) or 7(h) below, as many copies of the Time of Sale Prospectus, the Prospectus and any supplements and amendments (including prospectus wrappers) thereto or to the Registration Statement as Jefferies may request.

(b) The Company will cause to be prepared and delivered, at its expense, within one business day from the effective date of this Agreement, to Jefferies and the other Underwriters an “electronic Prospectus” to be used by the Underwriters in connection with the offering and sale of the Shares. As used herein, the term “electronic Prospectus” means a form of Time of Sale Prospectus, and any amendment or supplement thereto, that meets each of the following conditions: (i) it shall be encoded in an electronic format, satisfactory to Jefferies, including, but not limited to, portable document format, or PDF, that may be transmitted electronically by Jefferies and the other Underwriters to offerees and purchasers of the Shares; and (ii) it shall disclose the same information as the paper Time of Sale Prospectus, except to the extent that graphic and image material cannot be disseminated electronically, in which case such graphic and image material shall be replaced in the electronic Prospectus with a fair and accurate narrative description or tabular representation of such material, as appropriate. The Company hereby confirms that it has included or will include in the Prospectus filed pursuant to EDGAR or otherwise with the Commission and in the Registration Statement at the time it was declared effective an undertaking that, upon receipt of a request by an investor or his or her representative, the Company shall transmit or cause to be transmitted promptly, without charge, a paper copy of the Time of Sale Prospectus.

(c) Before amending or supplementing the Registration Statement, the Time of Sale Prospectus or the Prospectus, the Company will furnish to Jefferies a copy of each such proposed amendment or supplement and not file any such proposed amendment or supplement to which Jefferies reasonably objects, file with the Commission within the applicable period specified in Rule 424(b) under the Securities Act the Prospectus required to be filed pursuant to such Rule, and file any issuer free writing prospectus to the extent required by Rule 433 under the Securities Act.

(d) The Company will furnish to Jefferies a copy of each proposed free writing prospectus to be prepared by or on behalf of, used by, or referred to by the Company and not use or refer to any proposed free writing prospectus to which Jefferies reasonably objects.

21

(e) Not to take any action that would result in an Underwriter or the Company being required to file with the Commission pursuant to Rule 433(d) under the Securities Act a free writing prospectus prepared by or on behalf of the Underwriter that the Underwriter otherwise would not have been required to file thereunder.

(f) The Company will advise Jefferies promptly (i) when the Registration Statement has become effective, (ii) when any amendment to the Registration Statement has been filed or becomes effective, (iii) when any supplement to the Prospectus or any issuer free writing prospectus or any amendment to the Prospectus has been filed or distributed, (iv) of any request by the Commission for amendments or supplements to the Registration Statement, any Preliminary Prospectus or Prospectus or for additional information with respect thereto, or (v) of notice of institution of proceedings for, or the entry of a stop order, suspending the effectiveness of the Registration Statement or preventing or suspending the use of any Preliminary Prospectus, the Time of Sale Prospectus or the Prospectus; and if the Commission should enter such a stop order, the Company will use its best efforts to obtain the lifting or removal of such order as soon as possible.

(g) If the Time of Sale Prospectus is being used to solicit offers to buy the Shares at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus in order to make the statements therein, in the light of the circumstances, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement then on file, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, the Company will forthwith prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not, in the light of the circumstances when delivered to a prospective purchaser, be misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with applicable law.

(h) If, during such period after the time of issue of the Prospectus as in the opinion of counsel for the Underwriters the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is required by law to be delivered in connection with sales by an Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is delivered to a purchaser, not misleading, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Prospectus to comply with applicable law, the Company will forthwith prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to the dealers (whose names and addresses Jefferies will furnish to the Company) to which Shares may have been sold by Jefferies on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is delivered to a purchaser, be misleading or so that the Prospectus, as amended or supplemented, will comply with applicable law.

22

(i) If, at or after the time this Agreement is executed and delivered, it is necessary or appropriate for a post-effective amendment to the Registration Statement, or a Rule 462 Registration Statement, to be filed with the Commission and become effective before the Shares may be sold, the Company will use its best efforts to cause such post-effective amendment or such Registration Statement to be filed and become effective, and will pay any applicable fees in accordance with the Securities Act, as soon as possible; and the Company will advise Jefferies promptly and, if requested by Jefferies, will confirm such advice in writing, (i) when such post-effective amendment or such Registration Statement has become effective, and (ii) if Rule 430A under the Securities Act is used, when the Prospectus is filed with the Commission pursuant to Rule 424(b) under the Securities Act (which the Company agrees to file in a timely manner in accordance with such Rules).

(j) The Company will file in a timely manner all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act subsequent to the date of the Prospectus and for so long as the delivery of a prospectus (or, in lieu thereof, the notice referred to in Rule 173(a) under the Securities Act) is required in connection with the offering or sale of the Shares.

(k) The Company will promptly furnish such information or take such action as Jefferies may reasonably request and otherwise to qualify the Shares for offer and sale under the securities or “blue sky” laws of such states and other jurisdictions (domestic or foreign) as Jefferies shall reasonably request, and comply with such laws so as to permit the continuance of sales and dealings therein in such jurisdictions for as long as may be necessary to complete the distribution of the Shares; provided, however, that the Company shall not be required to qualify as a foreign corporation or to file a consent to service of process in any jurisdiction (excluding service of process with respect to the offer and sale of the Shares); and the Company will promptly advise Jefferies of the receipt by the Company of any notification with respect to the suspension of the qualification of the Shares for offer or sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose.

(l) The Company will make generally available to the Company’s security holders and to Jefferies as soon as practicable an earnings statement covering a period of at least 12 months beginning after the effective date of the Registration Statement (as defined in Rule 158(c) under the Securities Act), which shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder; provided that the Company will be deemed to have complied with such requirement by filing such earnings statement on EDGAR.

(m) The Company will use its best efforts to cause the Shares to be listed on the Exchange and to maintain such listing.

(n) During the period beginning on the date hereof and ending 90 days after the date of the Prospectus, and without the prior written consent of Jefferies on behalf of the Underwriters, not to (i) issue, offer, sell, pledge, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, make any short sale, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or Class B common stock, par value $0.001 per share, of the Company (together with the Common Stock, the “Stock”) or any securities convertible into or exercisable or exchangeable for Stock, (ii) enter into any swap, forward contract, hedging transaction or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Stock, whether such transaction described in clause (i) or (ii) above is to be settled by delivery of Stock or such other securities, in cash or otherwise, (iii) file any registration statement with the Commission relating to the offering of any shares of Stock or any securities convertible into or exercisable or exchangeable for Stock, or (iv) publicly disclose or announce an intention to effect any transaction specified in clause (i), (ii) or (iii) above.

(b) Each Selling Stockholder agrees to indemnify and hold harmless each Underwriter Indemnified Party against any loss, claim, damage, liability or expense (including, without limitation, any legal or other documented expenses reasonably incurred in connection with defending, settling, compromising, paying or investigation any such action or claim) as incurred, to which such Underwriter Indemnified Party may become subject, under the Securities Act, the Exchange Act, other federal or state statutory law or regulation, or the laws or regulations of foreign jurisdictions where Shares have been offered or sold or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Selling Stockholder), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus, the Time of Sale Prospectus, any free writing prospectus that the Company has used, referred to or filed, or is required to file, pursuant to Rule 433 of the Securities Act or the Prospectus (or any such amendment or supplement) or the omission or alleged omission to state therein a material fact necessary in order to make the statements, in the light of the circumstances under which they were made, not misleading; provided, however, that the foregoing indemnity agreement only applies to the extent that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, such preliminary prospectus, the Time of Sale Prospectus, such free writing prospectus or the Prospectus (or any such amendment or supplement), in reliance upon and in conformity with the Selling Stockholder Information relating to the Selling Stockholder furnished to the Company by such Selling Stockholder in writing expressly for use therein. Each of the Underwriters hereby acknowledges and agrees that the only

27

information that each Selling Stockholder has furnished to the Company in writing expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) of the Securities Act or the Prospectus (or any amendment or supplement to the foregoing) is (i) the legal name, address and the number of shares of Common Stock of the Company beneficially owned by such Selling Stockholder, before and after the offering, and (ii) the other information with respect to such Selling Stockholder which appears in the table (and corresponding footnotes) under the caption “Selling Stockholders” (with respect to such Selling Stockholder, the “Selling Stockholder Information”) in each case, in the Registration Statement, Preliminary Prospectus Supplement and the Final Prospectus Supplement. The aggregate liability of any Selling Stockholder under the indemnification provisions contained in this paragraph and the contribution provisions in Section 10 shall be limited to an amount equal to the aggregate Public Offering Price (less underwriting discounts and commissions) of the Shares sold by such Selling Stockholder under this Agreement.

(c) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless each PetIQ Party and the directors and officers of the Company who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each Selling Stockholder from and against any and all Losses caused by, arising from or based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Time of Sale Prospectus, any issuer free writing prospectus, any issuer information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any road show or the Prospectus or any amendment, supplement or wrapper thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or omission or alleged untrue statement or omission was made therein in reliance upon and in conformity with the Underwriter Information furnished to the Company in writing by such Underwriter through Jefferies expressly for use therein.

(d) In case any claim, action or other proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 10(a), 10(b) or 10(c) such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the reasonable and documented fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the reasonable and documented fees and expenses of more than one separate law firm (in addition to any local counsel) for all Underwriter Indemnified Parties and (ii) the fees and expenses of more than one separate law firm (in addition to any local counsel) for the PetIQ Parties, the directors and officers of the

28

Company who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section and the Selling Stockholders. In the case of any such separate law firm for the Underwriter Indemnified Parties, such law firm shall be designated in writing by Jefferies. In the case of any such separate law firm for the PetIQ Parties, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. In the case of any such separate law firm for the Selling Stockholders, such firm shall be designated in writing by the Selling Stockholders, it being understood that only one such firm may be designated for the Selling Stockholders collectively. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, then the indemnifying party agrees to indemnify the indemnified party from and against any Loss by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, which consent shall not be unreasonably withheld, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on Losses that are the subject matter of such proceeding.

(e) To the extent the indemnification provided for in Section 10(a), 10(b) or 10(c) is unavailable to an indemnified party or insufficient in respect of any Losses referred to therein (other than as a result of the limitations imposed on indemnification described in such preceding paragraphs of this Section 10), then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such Losses (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offer and sale of the Shares or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. The relative benefits received by the PetIQ Parties and/or the Selling Stockholders on the one hand and the Underwriters on the other hand in connection with the offer and sale of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offer and sale of the Shares (before deducting expenses) received by the Company and/or the Selling Stockholders and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of the PetIQ Parties and/or the Selling Stockholders on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by either PetIQ Party or any Selling Stockholder or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 10 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint.

29

(f) The PetIQ Parties, the Selling Stockholders and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 10 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 10(e). Notwithstanding the provisions of this Section 10, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 10 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any indemnified party at law or in equity.

(g) The indemnity and contribution provisions contained in this Section 10 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter, the PetIQ Parties, the officers or directors of the Company or any person controlling the Company and the Selling Stockholders and (iii) acceptance of and payment for any of the Shares.

11. Termination. The Underwriters may terminate this Agreement by notice given by Jefferies to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (a) there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Registration Statement, the Time of Sale Prospectus or the Prospectus, any material adverse effect, whether or not arising in the ordinary course of business, (b) trading generally shall have been suspended or materially limited on, or by, as the case may be, either the New York Stock Exchange or the NASDAQ Global Market, or by order of the Commission or FINRA or any other governmental authority, (c) trading of any securities of the Company shall have been suspended or materially limited on any exchange or in any over-the-counter market, (d) a material disruption in securities settlement, payment or clearance services in the United States or with respect to Clearstream or Euroclear systems in Europe shall have occurred, (e) any moratorium or material limitation on commercial banking activities shall have been declared by Federal or state authorities, (f) there shall have occurred any outbreak or escalation of hostilities, act of terrorism involving the United States or declaration by the United States of a national emergency or war, or (g) any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (f) or (g), makes it, in Jefferies’s judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus (exclusive of any supplement thereto).

12. Effectiveness; Defaulting Underwriters. (a) This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

(a) If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date (the “Defaulted Shares”), then Jefferies shall have the right to arrange for the purchase by one or more of the non-defaulting Underwriters, or any other underwriters, of all but not less than all of the Defaulted Shares in such amounts as may be agreed upon and upon the terms herein set forth. If within 36 hours after such default by any Underwriter, Jefferies does not arrange for the purchase of such Defaulted Shares, then the Company shall be entitled to a further period of 36 hours (which may

30

be waived by the Company) within which to procure another party or other parties satisfactory to Jefferies to purchase the Defaulted Shares on such terms as are acceptable to the Company. In the event that, within the respective prescribed periods, Jefferies notifies the Company that it has so arranged for the purchase of the Defaulted Shares, Jefferies shall have the right to postpone the Closing Date or an Option Closing Date, as the case may be, for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement, the Time of Sale Prospectus or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement, the Time of Sale Prospectus or the Prospectus which may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section 12 with like effect as if such person had originally been a party to this Agreement with respect to the Defaulted Shares.

(b) If, after giving effect to any arrangements for the purchase of Defaulted Shares by Jefferies or the Company as provided in subsection (a) above, the aggregate number of Defaulted Shares that remains unpurchased does not exceed one-tenth of the aggregate number of the Shares to be purchased on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase under this Agreement at the Closing Date or an Option Closing Date, as the case may be, and, in addition, to require each non-defaulting Underwriter to purchase its pro rata shares (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Defaulted Shares for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of Defaulted Shares by Jefferies or the Company as provided above, the aggregate number of Defaulted Shares that remains unpurchased does not exceed one-tenth of the aggregate number of the Shares to be purchased on the Closing Date or an Option Closing Date, as the case may be, or if the Company shall not exercise the right described in subsection (b) above to require the non-defaulting Underwriters to purchase the Defaulted Shares, then this Agreement (or, with respect to an Option Closing Date, the obligations of the Underwriters to sell the Additional Shares) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for expenses to be borne by the PetIQ Parties and the Underwriters as provided in Section 9 and the indemnification and contribution agreements in Section 10 hereof; but nothing herein shall relieve any defaulting Underwriter from liability for its default.

13. [RESERVED]

14. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the PetIQ Parties, the Selling Stockholders and the Underwriters set forth or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, the PetIQ Parties or any of the officers, directors, employees, agents or controlling persons referred to in Section 10 hereof or the Selling Stockholders, and will survive delivery of and payment for the Shares. The provisions of Sections 9 and 10 hereof shall survive the termination or cancellation of this Agreement.

15. Entire Agreement; No Advisory or Fiduciary Relationship. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement between the PetIQ Parties and the Selling Stockholders, on the one hand, and the Underwriters, on the other, with respect to the preparation of any Preliminary Prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

31

(b) The PetIQ Parties and the Selling Stockholders acknowledge that in connection with the offering of the Shares: (i) the Underwriters have acted at arm’s length, are not agents of, and owe no fiduciary duties to, the PetIQ Parties, the Selling Stockholders or any other person; (ii) the Underwriters owe the PetIQ Parties and the Selling Stockholders only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any; (iii) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offer or sale of the Shares and each of the PetIQ Parties and the Selling Stockholders has consulted its respective legal, accounting, regulatory and tax advisors to the extent that it deemed appropriate; and (iv) the Underwriters may have interests that differ from those of the PetIQ Parties and the Selling Stockholders. The PetIQ Parties and the Selling Stockholders waive to the full extent permitted by applicable law any claims they may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offer and sale of the Shares.

16. Intended Beneficiaries. This Agreement shall inure to the benefit of and be binding upon the Underwriters, the PetIQ Parties, the Selling Stockholders and their respective successors. No purchaser of Shares from any Underwriter shall be deemed to be a successor by reason merely of such purchase. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any individual or entity, other than the Underwriters, the PetIQ Parties, the Selling Stockholders and their respective successors, and the controlling persons, affiliates, officers and directors referred to in Section 10 hereof and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement is intended to be for the sole and exclusive benefit of the Underwriters, the PetIQ Parties, the Selling Stockholders and their respective successors, and said controlling persons, affiliates, officers and directors and their heirs and legal representatives, and for the benefit of no one else.

17. Partial Unenforceability. The invalidity or unenforceability of any Section, subsection, paragraph, clause or other provision of this Agreement shall not affect the validity or enforceability of any other Section, subsection, paragraph, clause or other provision hereof. If any Section, subsection, paragraph, clause or other provision of this Agreement is for any reason determined to be invalid or unenforceable, then there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make the remainder of this Agreement valid and enforceable.

18. Counterparts. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

19. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

20. TRIAL BY JURY. EACH OF THE PETIQ PARTIES (ON ITS BEHALF AND, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ON BEHALF OF ITS SUBSIDIARIES, STOCKHOLDERS AND AFFILIATES), EACH OF THE SELLING STOCKHOLDERS AND EACH OF THE UNDERWRITERS HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

21. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

PetIQ, Inc.

Ladies and Gentlemen:

We have acted as special counsel to PetIQ, Inc., a Delaware corporation (the “Company”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), of (i) the registration statement on Form S-3 (File No. 333-227186) (the “Registration Statement”) initially filed with the Commission on September 4, 2018, (ii) the base prospectus dated September 21, 2018 forming a part of the Registration Statement (the “Base Prospectus”) and (iii) the final prospectus supplement dated September 26, 2018 in the form filed with the Commission pursuant to Rule 424(b) under the Securities Act on September 27, 2018 (together with the Base Prospectus, the “Prospectus Supplement”) in connection with the offering by (i) the Company of 2,000,000 shares (the “Primary Shares”) of the Company’s Class A common stock, par value $0.001 per share (the “Class A Common Stock”), covered by the Registration Statement and (ii) certain selling stockholders named in the Prospectus Supplement (the “Selling Stockholders”) of 3,750,000 shares of Class A Common Stock (the “Secondary Shares” and together with the Primary Shares, the “Shares”). The Shares are being sold pursuant to the Underwriting Agreement, dated September 26, 2018 (the “Underwriting Agreement”), by and among the Company, PetIQ Holdings, LLC (“Holdco” and together with the Company, the “PetIQ Parties”) the Selling Stockholders and Jefferies LLC, as the representative of the underwriters named in Schedule I thereto (the “Underwriters”). We understand that the Shares are to be offered and sold in the manner described in the Prospectus Supplement.

This opinion letter is being delivered in accordance with the requirements of Item 601(b)(5) of Regulation S-K promulgated under the Act.

In rendering the opinion set forth below, we have examined and relied upon such certificates, corporate records, agreements, instruments and other documents that we considered necessary or appropriate as a basis for the opinion, including (i) the Registration Statement, (ii) the Prospectus Supplement and (iii) the Underwriting Agreement. In our examination, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as certified or photostatic copies, the authenticity of the originals of such latter documents and that the Underwriting Agreement constitutes the valid and binding obligation of each party thereto (other than the PetIQ Parties) enforceable against each such party in accordance with its terms. As to any facts material to this opinion that we did not independently establish or verify, we have relied upon oral or written statements and representations of officers and other representatives of the Company and others.

Based upon the foregoing and subject to the assumptions, qualifications and limitations set forth herein, we are of the opinion that (i) the Primary Shares have been duly authorized and, when the Primary Shares are delivered to the Underwriters against payment of the agreed consideration therefor in accordance with the Underwriting Agreement, the Primary Shares will be validly issued, fully paid and nonassessable, and (ii) the Secondary Shares have been duly authorized and are validly issued, fully paid and nonassessable.

The foregoing opinion is limited to the General Corporation Law of the State of Delaware (including the statutory provisions, the applicable provisions of the Delaware Constitution and reported judicial decisions interpreting the foregoing). We express no opinion with respect to any other laws, statutes, regulations or ordinances.

We hereby consent to the filing of this opinion as an exhibit to the Company’s Current Report on Form 8-K to be filed with the Commission on October 2, 2018 and its incorporation by reference into the Registration Statement and to the reference to our firm under the caption “Legal Matters” in the Prospectus Supplement included in the Registration Statement. In giving such consent, we do not concede that we are experts within the meaning of the Securities Act or the rules and regulations thereunder or that this consent is required by Section 7 of the Securities Act.
