Ladies and Gentlemen:

Certain stockholders named in Schedule 2 hereto (the “Selling Stockholders”) of ▇▇▇▇▇▇ Health Company, a Delaware corporation (the “Company”), propose to sell to the several underwriters listed in Schedule 1 hereto (the “Underwriters”), an aggregate of 20,000,000 shares (the “Underwritten Shares”) of common stock, par value $0.01 per share (“Common Stock”), of the Company. The Underwritten Shares are herein referred to as the “Shares.” The shares of Common Stock of the Company to be outstanding after giving effect to the sale of the Shares are referred to herein as the “Stock.” In the event only one underwriter is listed in Schedule 1 hereto, any references in this Agreement to the “Underwriters” shall be deemed to refer to the sole underwriter in the singular form listed in such Schedule 1.

The Company and the Selling Stockholders hereby confirm their agreement with the Underwriters concerning the purchase and sale of the Shares, as follows:

1. Registration Statement. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a registration statement on Form S-3 (File No. 333-277418), including a prospectus, relating to the Shares. Such registration statement, as amended at the time it became effective, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Preliminary Prospectus” means each prospectus, including any preliminary prospectus supplement, included in such registration statement (and any amendments thereto) before effectiveness, any prospectus filed with the Commission pursuant to Rule 424(a) under the Securities Act and the prospectus included in the Registration Statement at the time of its effectiveness that omits Rule 430 Information, and the term “Prospectus” means the prospectus in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Shares. If the Company has filed an abbreviated registration statement pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement. Any reference in this underwriting agreement (this “Agreement”) to the Registration Statement, any Preliminary Prospectus or the

Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, as of the effective date of the Registration Statement or the date of such Preliminary Prospectus or the Prospectus, as the case may be, and any reference to “amend”, “amendment” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”) that are deemed to be incorporated by reference therein. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus.

At or prior to the Applicable Time (as defined below), the Company had prepared the following information (collectively with the pricing information set forth on Annex A, the “Pricing Disclosure Package”): a Preliminary Prospectus dated September 3, 2025 and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex A hereto.

“Applicable Time” means 4:45 P.M., New York City time, on September 3, 2025.

2. Purchase of the Shares.

(a) Each of the Selling Stockholders agrees, severally and not jointly, to sell the Underwritten Shares to the Underwriters as provided in this Agreement, and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase at a price per share of $15.111 (the “Purchase Price”) from each of the Selling Stockholders the number of Underwritten Shares (to be adjusted by the Underwriters so as to eliminate fractional shares) determined by multiplying the aggregate number of Underwritten Shares to be sold by each of the Selling Stockholders as set forth opposite their respective names in Schedule 2 hereto by a fraction, the numerator of which is the aggregate number of Underwritten Shares to be purchased by such Underwriter as set forth opposite the name of such Underwriter in Schedule 1 hereto and the denominator of which is the aggregate number of Underwritten Shares to be purchased by all the Underwriters from all of the Selling Stockholders hereunder.

(b) The Selling Stockholders understand that the Underwriters intend to make a public offering of the Shares, and initially to offer the Shares on the terms set forth in the Pricing Disclosure Package. The Selling Stockholders acknowledge and agree that the Underwriters may offer and sell Shares to or through any affiliate of an Underwriter.

(c) Payment for the Shares shall be made by wire transfer in immediately available funds to the account specified by each of the Selling Stockholders to the Underwriters in the case of the Underwritten Shares, via teleconference at 10:00 A.M. New York City time on September 5, 2025, or at such other time or place on the same or such other date, not later than the fifth business day thereafter, as the Underwriters and each of the Selling Stockholders may agree upon in writing. The time and date of such payment for the Underwritten Shares is referred to herein as the “Closing Date.”

Payment for the Shares to be purchased on the Closing Date shall be made against delivery to the Underwriters of the Shares to be purchased on such date with any transfer taxes payable in connection with the sale of such Shares duly paid by the Selling Stockholders. Delivery of the Shares shall be made through the facilities of The Depository Trust Company (“DTC”) unless the Underwriters shall otherwise instruct.

(d) Each of the Company and each Selling Stockholder acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company and the Selling Stockholders with respect to the offering of Shares contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company, the Selling Stockholders or any other person. Additionally, no Underwriter is advising the Company, the Selling Stockholders or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company and the Selling Stockholders shall consult with their own advisors concerning such matters and each shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and no Underwriter shall have any responsibility or liability to the Company or the Selling Stockholders with respect thereto. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company or the Selling Stockholders. Moreover, each Selling Stockholder acknowledges and agrees that, although the Underwriters may be required or choose to provide certain Selling Stockholders with certain Regulation Best Interest and Form CRS disclosures in connection with the offering, the Underwriters are not making a recommendation to any Selling Stockholder to participate in the offering, enter into a “lock-up” agreement, or sell any Shares at the price determined in the offering, and nothing set forth in such disclosures is intended to suggest that any Underwriter is making such a recommendation.

As used herein, the term “Prospectus Delivery Period” means such period of time after the first date of the public offering of the Shares as in the opinion of counsel for the Underwriters a prospectus relating to the Shares is required by law to be delivered (or required to be delivered but for Rule 172 under the Securities Act) in connection with sales of the Shares by any Underwriter or dealer.

(c) Amendments or Supplements, Issuer Free Writing Prospectuses. Before making, preparing, using, authorizing, approving, referring to or filing any Issuer Free Writing Prospectus, and before filing any amendment or supplement to the Registration Statement, the Pricing Disclosure Package or the Prospectus, whether before or after the time that the Registration Statement becomes effective, the Company will furnish to the Underwriters and counsel for the Underwriters a copy of the proposed Issuer Free Writing Prospectus, amendment or supplement for review and will not make, prepare, use, authorize, approve, refer to or file any such Issuer Free Writing Prospectus or file any such proposed amendment or supplement to which the Underwriters reasonably object in a timely manner.

Pricing Disclosure Package or any such Issuer Free Writing Prospectus is delivered to a purchaser, not misleading; (vii) of the receipt by the Company of any notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act; and (viii) of the receipt by the Company of any notice with respect to any suspension of the qualification of the Shares for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Company will use its reasonable best efforts to prevent the issuance of any such order suspending the effectiveness of the Registration Statement, preventing or suspending the use of any Preliminary Prospectus, any of the Pricing Disclosure Package or the Prospectus or suspending any such qualification of the Shares and, if any such order is issued, will use its reasonable best efforts to obtain as soon as possible the withdrawal thereof.

(e) Ongoing Compliance. (1) If during the Prospectus Delivery Period (i) any event or development shall occur or condition shall exist as a result of which the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, not misleading or (ii) it is necessary to amend or supplement the Prospectus to comply with law, the Company will immediately notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission and furnish to the Underwriters and to such dealers as the Underwriters may designate such amendments or supplements to the Prospectus (or any document to be filed with the Commission and incorporated by reference therein) as may be necessary so that the statements in the Prospectus as so amended or supplemented (or any document to be filed with the Commission and incorporated by reference therein) will not, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus will comply with law and (2) if at any time prior to the Closing Date (i) any event or development shall occur or condition shall exist as a result of which the Pricing Disclosure Package as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances existing when the Pricing Disclosure Package is delivered to a purchaser, not misleading or (ii) it is necessary to amend or supplement the Pricing Disclosure Package to comply with law, the Company will immediately notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission (to the extent required) and furnish to the Underwriters and to such dealers as the Underwriters may designate such amendments or supplements to the Pricing Disclosure Package (or any document to be filed with the Commission and incorporated by reference therein) as may be necessary so that the statements in the Pricing Disclosure Package as so amended or supplemented will not, in the light of the circumstances existing when the Pricing Disclosure Package is delivered to a purchaser, be misleading or so that the Pricing Disclosure Package will comply with law.

For a period of 45 days after the date of the Prospectus, the Company will not (i) offer, pledge, sell, 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, lend, or otherwise transfer or dispose of, directly or indirectly, or publicly file with, the Commission a registration statement under the Securities Act relating to, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, or publicly disclose the intention to undertake any of the foregoing (provided that the Company shall provide written notice to the Underwriters at least two business days prior to any confidential or non-public submission of a registration statement described in this clause (i)), or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock or any such other securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, without the prior written consent of the Underwriters, other than the Shares to be sold hereunder.

The restrictions described above do not apply to (i) the issuance of shares of Stock or securities convertible into or exercisable for shares of Stock pursuant to the conversion or exchange of convertible or exchangeable securities or the exercise of warrants or options (including net exercise) or the settlement of restricted stock units (“RSUs”) or performance stock units (including net settlement), in each case outstanding on the date of this Agreement and described in the Prospectus; (ii) grants of stock options, stock awards, restricted stock, RSUs, performance stock units, or other equity awards and the issuance of shares of Stock or securities convertible into or exercisable or exchangeable for shares of Stock (whether upon the exercise of stock options, settlement of RSUs or otherwise), in each case, pursuant to or subject to the terms of an equity compensation plan in effect as of the Closing Date and described in the Prospectus (the “Compensation Plans”), provided that such recipients that are executive officers or directors of the Company enter into a lock-up agreement with the Underwriters substantially in the form of Exhibit A hereto; (iii) entry into one or more agreements

providing for, and the issuance of, up to 10% of the outstanding shares of Stock, or securities convertible into, exercisable for, or which are otherwise exchangeable for, Stock, immediately following the Closing Date, in acquisitions of the securities, business, property or assets of another person or entity, joint ventures, commercial relationships or other similar strategic transactions or pursuant to any employee benefit plan assumed by the Company in connection with any such acquisition, provided that such recipients enter into a lock-up agreement with the Underwriters; or (iv) the filing of any registration statement on Form S-8 relating to securities granted or to be granted pursuant to any Compensation Plan described in the Prospectus or any assumed benefit plan pursuant to an acquisition or similar strategic transaction.

If the Company is not eligible to file an automatic shelf registration statement, the Company will, prior to the Renewal Deadline, if it has not already done so, file a new shelf registration statement relating to the Shares, in a form satisfactory to the Underwriters, and will use its best efforts to cause such registration statement to be declared effective within 180 days after the Renewal Deadline. The Company will take all other action necessary or appropriate to permit the issuance and sale of the Shares to continue as contemplated in the expired registration statement relating to the Shares. References herein to the Registration Statement shall include such new automatic shelf registration statement or such new shelf registration statement, as the case may be.

6. Further Agreements of the Selling Stockholders. Each of the Selling Stockholders severally covenants and agrees with each Underwriter that:

(a) It has not used, authorized use of, referred to or participated in the planning for use of, and will not use, authorize use of, refer to or participate in the planning for use of, any “free writing prospectus,” as defined in Rule 405 under the Securities Act (which term includes use of any written information furnished to the Commission by the Company and not incorporated by reference into the Registration Statement and any press release issued by the Company) other than (i) a free writing prospectus that contains no “issuer information” (as defined in Rule 433(h)(2) under the Securities Act) (including through incorporation by reference) that was not included in the Preliminary Prospectus or a previously filed Issuer Free Writing Prospectus, (ii) any Issuer Free Writing Prospectus listed on Annex A or prepared pursuant to Section 3(c) or Section 4(f) above (including any electronic road show), or (iii) any free writing prospectus prepared by such underwriter and approved by the Company in advance in writing (each such free writing prospectus referred to in clauses (i) or (iii), an “Underwriter Free Writing Prospectus”).

untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in paragraph (d) below.

The Company agrees to indemnify and hold harmless each Selling Stockholder from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable legal fees and other reasonable expenses incurred and documented in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, any road show as defined in Rule 433(h) under the Securities Act (a “road show”) or any Pricing Disclosure Package (including any Pricing Disclosure Package that has subsequently been amended), or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, the Selling Stockholder Information.

(c) Indemnification of the Underwriters by the Selling Stockholders. Each of the Selling Stockholders severally in proportion to the number of Shares to be sold by such Selling Stockholder hereunder agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, in each case to the extent, and only to the extent, that such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any Selling Stockholder Information relating to such Selling Stockholder in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Preliminary Prospectus, any Issuer Free Writing Prospectus or the Pricing Disclosure Package.

(d) Indemnification of the Company and the Selling Stockholders by the Underwriters. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each of the Selling Stockholders to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Preliminary Prospectus, any Issuer Free Writing Prospectus, any road show or any Pricing

Disclosure Package (including any Pricing Disclosure Package that has subsequently been amended), it being understood and agreed upon that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: information contained in the third, tenth and eleventh paragraphs under the caption “Underwriting.”

(e) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to the preceding paragraphs of this Section 9, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under the preceding paragraphs of this Section 9 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under the preceding paragraphs of this Section 9. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person, upon request of the Indemnified Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 9 that the Indemnifying Person may designate in such proceeding and shall pay the reasonable fees and expenses in such proceeding and shall pay the reasonable and documented fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person 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 Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such reasonable and documented fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Underwriters and any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company and any such separate firm for the Selling Stockholders shall be designated in writing by the Selling Stockholders selling a majority of the Shares under this Agreement. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement. Notwithstanding the

foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person 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 the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(f) Contribution. If the indemnification provided for in paragraphs (a), (b), (c) or (d) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholders, on the one hand, and the Underwriters, on the other, from the offering of the Shares or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and the Selling Stockholders, on the one hand, and the Underwriters, on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholders, on the one hand, and the Underwriters, on the other, shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Selling Stockholders from the sale of the Shares and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Shares. The relative fault of the Selling Stockholders, on the one hand, and the Underwriters, on the other, 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 the Company and the Selling Stockholders or by the Underwriters, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(g) Limitation on Liability. The Company, the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to paragraph (f) above were determined by pro rata allocation (even if the Selling Stockholders or 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 paragraph (f) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (f) above shall be deemed to include, subject to the limitations

set forth above, any reasonable legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of paragraphs (f) and (g), in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Shares 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 Underwriters’ obligations to contribute pursuant to paragraphs (f) and (g) are several in proportion to their respective purchase obligations hereunder and not joint.

(h) Selling Stockholder Liability. The liability of each Selling Stockholder under the indemnity and contribution agreements contained in Sections 9(c) and 9(f) shall not exceed the aggregate gross proceeds after underwriting commissions and discounts, but before expenses, to such Selling Stockholder from the sale of the Shares sold by such Selling Stockholder pursuant to this Agreement.

(i) Non-Exclusive Remedies. The remedies provided for in this Section 9 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

10. Effectiveness of Agreement. This Agreement shall become effective as of the date first written above.

11. Termination. This Agreement may be terminated in the absolute discretion of the Underwriters, by notice to the Company and the Selling Stockholders, if after the execution and delivery of this Agreement and on or prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by any of the New York Stock Exchange or The Nasdaq Stock Market; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Underwriters, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Shares on the Closing Date on the terms and in the manner contemplated by this Agreement, the Pricing Disclosure Package and the Prospectus.

12. Defaulting Underwriter.

(a) If, on the Closing Date any Underwriter defaults on its obligation to purchase the Shares that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Shares by other persons satisfactory to the Company and the Selling Stockholders on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Shares, then the Company and the Selling Stockholders shall be

entitled to a further period of 36 hours within which to procure other persons reasonably satisfactory to the non-defaulting Underwriters to purchase such Shares on such terms. If other persons become obligated or agree to purchase the Shares of a defaulting Underwriter, either the non-defaulting Underwriters or the Company and the Selling Stockholders may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company, counsel for the Selling Stockholders or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 12, purchases Shares that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters, the Company and the Selling Stockholders as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date does not exceed one-eleventh of the aggregate number of Shares to be purchased on such date, then the Company and the Selling Stockholders shall have the right to require each non-defaulting Underwriter to purchase the number of Shares that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the number of Shares that such Underwriter agreed to purchase on such date) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters, the Company and the Selling Stockholders as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date exceeds one-eleventh of the aggregate amount of Shares to be purchased on such date, or if the Company and the Selling Stockholders shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 12 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 13 hereof and except that the provisions of Section 9 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company, the Selling Stockholders or any non-defaulting Underwriter for damages caused by its default.

13. Payment of Expenses.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company will pay or cause to be paid all costs and expenses incident to the performance of its and the Selling Stockholders’ obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Shares and, subject to the last sentence of this paragraph, any stamp or other issuance or transfer taxes payable in that connection; (ii) the costs incident to the

preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Pricing Disclosure Package and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the fees and expenses of the Company’s counsel and independent accountants, and the fees and expenses of counsel to the Selling Stockholders pursuant to the Second Amended and Restated Registration Rights Agreement, dated as of November 19, 2020 by and among the Company and certain stockholders, or as otherwise approved by the Company; (iv) the reasonable fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Shares under the laws of such jurisdictions as the Underwriters may designate with the prior approval of the Company (such approval not to be unreasonably withheld, conditioned or delayed) and the preparation, printing and distribution of a Blue Sky Memorandum (including the related reasonable fees and expenses of counsel for the Underwriters pursuant to this clause (iv) which shall not exceed $10,000); (v) the cost of preparing stock certificates, if applicable; (vi) the costs and charges of any transfer agent and any registrar; (vii) all reasonable expenses and application fees incurred in connection with any filing with, and clearance of the offering by, FINRA (such application fees and the fees and disbursements of counsel for the Underwriters pursuant to this clause (vii) shall not exceed $25,000); (viii) all expenses incurred by the Company in connection with any “road show” presentation to potential investors; and (ix) all expenses and application fees related to the listing of the Shares on the Nasdaq Market. It is, however, understood that except as provided in this Section 13 or Section 9 hereof, the Underwriters shall pay all of their own costs and expenses, including, without limitation, the fees and disbursements of their counsel, stock transfer taxes payable on resale of any Shares by them and any advertising expenses connected with any offers they make. Each Selling Stockholder further agrees with the Underwriters to pay (directly or by reimbursement) any stock transfer taxes, stamp duties and other similar taxes incident to the sale and delivery of the Shares to be sold by such Selling Stockholder to the Underwriters hereunder.

(b) If (i) this Agreement is terminated pursuant to Section 11, (ii) the Company or the Selling Stockholders for any reason fail to tender the Shares for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Shares for any reason permitted under this Agreement, the Company agrees to reimburse the Underwriters for all out-of-pocket costs and expenses (including the reasonable and documented fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

14. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to herein, and the affiliates of each Underwriter referred to in Section 9 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Shares from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

15. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company, the Selling Stockholders and the Underwriters contained in this Agreement or made by or on behalf of the Company, the Selling Stockholders or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall

survive the delivery of and payment for the Shares and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company, the Selling Stockholders or the Underwriters or the directors, officers, controlling persons or affiliates referred to in Section 9 hereof.

16. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act ; and (d) the term “significant subsidiary” has the meaning set forth in Rule 1-02 of Regulation S-X under the Exchange Act.

Each of the Company and the Selling Stockholders waive any objection which it may now or hereafter have to the laying of venue of any such suit or proceeding in such courts. Each of the Company and the Selling Stockholders agree that final judgment in any such suit, action or proceeding brought in such court shall be conclusive and binding upon the Company and each Selling Stockholder, as applicable, and may be enforced in any court to the jurisdiction of which Company and each Selling Stockholder, as applicable, is subject by a suit upon such judgment.

(d) Waiver of Jury Trial. Each of the parties hereto hereby waives any right to trial by jury in any suit or proceeding arising out of or relating to this Agreement.

(e) Recognition of the U.S. Special Resolution Regimes.

(i) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(ii) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

Annex B-1

Form of Opinion of Counsel for the Company

1.	The Company is validly existing as a corporation in good standing under the laws of the State of Delaware.

2.	The Company has corporate power to own its properties and conduct its business as described in the Pricing Prospectus and the Final Prospectus, and the Company has corporate power to enter into the Underwriting Agreement and to perform its obligations thereunder.

The Securities have been duly authorized by all necessary corporate action of the Company, have been validly issued by the Company and are fully paid and nonassessable; and the holders of outstanding shares of capital stock of the Company are not entitled to any preemptive rights to subscribe for the Securities under the Certificate of Incorporation or By-Laws of the Company or the General Corporation Law of the State of Delaware.

The statements under the heading “Description of Capital Stock” in the Pricing Prospectus and the Final Prospectus, insofar as such statements purport to summarize certain provisions of the Securities and the Certificate of Incorporation of the Company, provide a fair summary of such provisions; the statements under the heading “Underwriting” in the Pricing Prospectus and the Final Prospectus, insofar as such statements purport to summarize certain provisions of the Underwriting Agreement, provide a fair summary of such provisions; and the statements under the heading “Material U.S. Federal Income Tax Considerations for Non-U.S. Holders” in the Pricing Prospectus and the Final Prospectus, insofar as such statements purport to summarize certain federal income tax laws of the United States, constitute a fair summary of the principal U.S. federal income tax consequences to Non-U.S. Holders (as defined therein) of an investment in the Securities.

5.	The execution and delivery of the Underwriting Agreement have been duly authorized by all necessary corporate action of the Company, and the Underwriting Agreement has been duly executed and delivered by the Company.

The performance by the Company of its obligations in the Underwriting Agreement will not, (a) require any consent, approval, authorization, registration or qualification of or with any governmental authority of the United States or the State of New York that in our experience normally would be applicable to general business entities with respect to performance, except such as have been obtained or effected under the Securities Act and the Securities Exchange Act of 1934, as amended (but we express no opinion relating to any state securities or Blue Sky laws), (b) result in a breach of any of the terms and provisions of, or constitute a default under, any of the agreements of the Company filed as an exhibit to the Registration Statement, or a violation of the Certificate of Incorporation or By-Laws of the Company or (c) result in a violation of any United States federal or New

York State law or published rule or regulation that in our experience normally would be applicable to general business entities with respect to such performance (but we express no opinion relating to the United States federal securities laws or any state securities or Blue Sky laws).

7.	The Company is not required to register as an “investment company” as such term is defined in the U.S. Investment Company Act of 1940, as amended.

Form of 10b-5 Statement of Counsel for the Company

The Registration Statement (except the financial statements and schedules and other financial data included therein, as to which we express no view), at the time it became effective, and the Final Prospectus (except as aforesaid), as of the date thereof, appeared on their face to be appropriately responsive in all material respects to the requirements of the Securities Act and the applicable rules and regulations thereunder.

No information has come to our attention that causes us to believe that the Registration Statement (except the financial statements and schedules and other financial data included therein, as to which we express no view), at the time it became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

No information has come to our attention that causes us to believe that the Pricing Prospectus, considered together with the amount and the price to the public of the Securities on the front cover of the Final Prospectus (except in each case the financial statements and schedules and other financial data included therein, as to which we express no view), at [● p.m.] (Eastern time) on September [●], 2025, contained an untrue statement of a material fact or omitted 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.

No information has come to our attention that causes us to believe that the Final Prospectus (except the financial statements and schedules and other financial data included therein, as to which we express no view), as of the date thereof or hereof, contained or contains an untrue statement of a material fact or omitted or omits 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.

Annex B-2

Form of Opinion of Delaware Counsel for the Company

1.	The execution and delivery by the Company of the Underwriting Agreement and the performance by the Company of its obligations under the Underwriting Agreement will not violate the Certificate of Incorporation, the Bylaws or any Delaware law, rule or regulation.

No authorization, approval, consent or order of any Delaware court or Delaware governmental authority is required to be obtained by the Company solely in connection with the execution and delivery by the Company of the Underwriting Agreement and the performance by the Company of its obligations under the Underwriting Agreement.

Annex B-3

Form of Opinion of General Counsel for the Company

1.	Each subsidiary of the Company listed on Schedule I hereto has been duly organized and is validly existing and in good standing under the laws of its respective jurisdiction of organization.

2.	To the best of my knowledge, the statements set forth under the heading “Risk Factors” in the Registration Statement, the Pricing Prospectus and the Final Prospectus, insofar as such statements purport to summarize certain legal and regulatory matters, provide a fair summary of such matters.

To the best of my knowledge, (a) there are no current or pending legal, governmental or regulatory actions, suits or proceedings that are required under the Securities Act to be described in the Registration Statement, the Pricing Prospectus or the Final Prospectus and that are not so described in the Registration Statement, the Pricing Prospectus and the Final Prospectus and (b) there are (i) no contracts or other documents that are required under the Securities Act to be filed as exhibits to the Registration Statement that have not been so filed as exhibits to the Registration Statement and (ii) no statutes, regulations, contracts or other documents are required under the Securities Act to be described in the Registration Statement, the Pricing Prospectus or the Final Prospectus that have not been so described in the Registration Statement, the Pricing Prospectus and the Final Prospectus.

4.	All outstanding shares of capital stock of the Company have been duly and validly authorized and issued and are fully paid and non-assessable.

To the best of my knowledge, from January 1, 2021 to the present the Company, on a consolidated basis, has complied in all material respects with the Food and Drug Laws with respect to its activities and services regulated by the U.S. Food and Drug Administration (“FDA”) or the Drug Enforcement Administration (“DEA”), as applicable, except as described in the Registration Statement, the Pricing Prospectus and the Final Prospectus. “Food and Drug Laws” means the Federal Food, Drug, and Cosmetic Act, the Public Health Service Act, the federal Controlled Substances Act, the applicable rules or regulations of the FDA, the U.S. Department of Health and Human Services, the Centers for Disease Control and Prevention, and the DEA, including those in Titles 21, 42, and 45 of the Code of Federal Regulations, and the applicable laws and regulations of other comparable governmental or regulatory authorities applicable to the testing, manufacture, processing (including by sterilizing or irradiating) or storage of any article tested, manufactured, processed or stored by the Company, on a consolidated basis.

Annex B-4

Form of Opinion of Counsel for the Warburg Selling Stockholders

1.	Each of the WP Selling Stockholders is validly existing and in good standing as a limited partnership under the law of the State of Delaware.

2.	Each of the WP Selling Stockholders has limited partnership power to sell the Securities, to execute and deliver the Underwriting Agreement and to perform its obligations thereunder.

The execution, delivery and performance of the Underwriting Agreement have been duly authorized by all necessary limited partnership action of each WP Selling Stockholder, and the Underwriting Agreement has been duly executed and delivered by each WP Selling Stockholder under the law of the State of New York.

The sale of the Securities by the WP Selling Stockholders to the Underwriters pursuant to the Underwriting Agreement does not, and the execution, delivery and performance by the WP Selling Stockholders of their obligations in the Underwriting Agreement will not, (a) require any consent, approval, authorization, registration or qualification of or with any governmental authority of the United States or the State of New York or pursuant to the Delaware Revised Uniform Limited Partnership Act, in each case, that in our experience normally would be applicable to general business entities with respect to such sale, execution, delivery or performance, except such as have been obtained or effected under the Securities Act and the Securities Exchange Act of 1934, as amended (but we express no opinion relating to any state securities or Blue Sky laws), or (b) result in a violation of the Certificate of Limited Partnership or the Amended and Restated Limited Partnership Agreement of any of the WP Selling Stockholders or other agreement or instrument identified on Annex I hereto, or (c) result in a violation of any United States federal or New York State law or published rule or regulation thereunder or the Delaware Revised Uniform Limited Partnership Act that in our experience normally would be applicable to general business entities with respect to such sale or performance (but we express no opinion relating to the United States federal securities laws or any state securities or Blue Sky laws).

Assuming that (a) The Depository Trust Company (“DTC”) is a “clearing corporation” as defined in Section 8-102(a)(5) of the Uniform Commercial Code as in effect on the date hereof in the State of New York (the “UCC”), and (b) each of the Underwriters acquires its interest in the Securities it has purchased without notice of any adverse claim (within the meaning of Section 8-105 of the UCC), each Underwriter that has purchased Securities from the WP Selling Stockholders delivered on the date hereof to DTC, made payment therefor pursuant to the Underwriting Agreement and had such Securities credited to a securities account of such Underwriter maintained with DTC will have acquired a securities entitlement (within the meaning of Section 8-102(a)(17) of the UCC) to such Securities, and no action based on an adverse claim may be asserted against such Underwriter with respect to such security entitlement.

Annex B-5

Form of Opinion of Counsel for the GTCR Selling Stockholders

1.	The Underwriting Agreement has been duly executed and delivered by or on behalf of each Selling Stockholder under the law of the State of New York.

The execution, delivery and performance of the Underwriting Agreement by each Selling Stockholder, and the sale by each Selling Stockholder of the Shares to be sold by such Selling Stockholder in accordance with the provisions of the Underwriting Agreement, do not and will not (i) violate or conflict with any of the terms or provisions of the certificate of limited partnership, limited partnership agreement and/or other organizational document of such Selling Stockholder, (ii) result in any breach of any of the terms and provisions of, or constitute a default (or an event which with notice or lapse of time, or both, would constitute a default) under, any agreement listed on the Specified Contracts Schedule (the “Specified Contracts”), it being expressly understood that in each case we express no opinion as to compliance with any financial covenant or test or cross-default provision in any Specified Contract, (iii) violate or conflict with any judgment, decree or order identified to us by such Selling Stockholder (we note that none were identified) of any court or any judicial, regulatory or other legal or governmental agency or body having jurisdiction over such Selling Stockholder, or (iv) violate any Specified Law, except in each of the cases of clause (ii), for any such violation, conflict, breach or default which has been waived by the party or parties with power to waive such violation, conflict, breach or default.

No consent, approval, authorization, or order of, or qualification with, any governmental body or agency is required to be obtained by any Selling Stockholder under any Specified Law with respect to the sale of the Shares by such Selling Stockholder and the performance by such Selling Stockholder of its obligations under the Underwriting Agreement.

Upon payment for the Shares to be sold by the Selling Stockholders to the Underwriters pursuant to the Underwriting Agreement, delivery of such Shares, as directed by the Underwriters, to Cede & Co. (“Cede”) or such other nominee as may be designated by the Depository Trust Company (“DTC”), registration of such Shares in the name of Cede or such other nominee and the crediting of such Shares on the records of DTC to securities accounts of such Underwriters: (A) under Section 8-501 of the Uniform Commercial Code as in effect in the State of New York (the “UCC”), such Underwriters will acquire a “security entitlement” (within the meaning of Section 8-102(a)(17) of the UCC) in respect of such Shares; and (B) assuming such Underwriters have so acquired such security entitlement without notice of any adverse claim (within the meaning of Sections 8-102(a)(1) and 8-105 of the UCC) to such Shares, no action based on any adverse claim (within the meaning of Sections 8-102(a)(1) and 8-105 of the UCC) to such Shares may be asserted against such Underwriters with respect to such security entitlements. For purposes of our opinion in this paragraph 4, we have assumed that when such payment, delivery, registration and crediting occur, (x) the Shares being sold by the Selling Stockholders will have been registered in the name of Cede or such other nominee as may be designated by DTC, in each case on the Company’s share registry in accordance with its certificate of incorporation, by-laws and applicable law, (y) DTC will be a “clearing corporation” and thus a “securities intermediary” within the meaning of Section 8-102 of the UCC and its jurisdiction for purposes of Article 8 of the UCC will be the State of the New York and (z) appropriate entries to the securities account or accounts in the name of such Underwriters on the records of DTC will have been made pursuant to the UCC.

In the event only one underwriter is listed in Schedule 1 to the Underwriting Agreement, any references in this Agreement to the “Underwriters” shall be deemed to refer to the sole underwriter in the singular form listed in such Schedule 1. Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Underwriting Agreement.

In consideration of the Underwriters’ agreement to purchase and make the Public Offering of the Securities, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of the Underwriters, the undersigned will not, and will not cause any direct or indirect affiliate (provided, that any “portfolio company” (as such term is customarily used among institutional investors) of the undersigned, or any entity controlled by any such portfolio company, shall not be considered an affiliate of the undersigned) to, during the period beginning on the date of this letter agreement (this “Letter Agreement”) and ending at the close of business on the date that is 45 days after the date of the final prospectus relating to the Public Offering (the “Prospectus”) (such period, the “Restricted Period”), (1) offer, pledge, sell, 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, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (including without limitation, Common Stock or such other securities which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant) (collectively with the Common Stock, the “Lock-Up Securities”), (2) enter into any hedging, swap or other agreement or transaction that transfers, in whole or in part, any of the economic consequences of ownership of the Lock-Up Securities, whether any such transaction

The undersigned acknowledges and agrees that the foregoing precludes the undersigned from engaging in any hedging or other transactions or arrangements (including, without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof, forward, swap or any other derivative transaction or instrument, however described or defined) designed or intended, or which could reasonably be expected to lead to or result in, a sale, loan, pledge or other disposition or transfer (whether by the undersigned or any other person) of any economic consequences of ownership, in whole or in part, directly or indirectly, of any Lock-Up Securities, whether any such transaction or arrangement (or instrument provided for thereunder) would be settled by delivery of Lock-Up Securities, in cash or otherwise, or to publicly disclose the intention to undertake any of the foregoing. The undersigned represents and warrants that the undersigned is not, has not caused or directed any of its affiliates to be or become, and is not aware of any of its affiliates (provided, that any “portfolio company” (as such term is customarily used among institutional investors) of the undersigned, or any entity controlled by any such portfolio company, shall not be considered an affiliate of the undersigned) being, currently a party to any agreement or arrangement that is designed to or which reasonably could be expected to lead to or result in any activity prohibited by this Letter Agreement during the Restricted Period.

In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Letter Agreement.
