1.2Employment and Term of Agreement. Effective November 1, 2023 (the “Start Date”), Bio-Techne agrees to employ Executive and Executive hereby accepts such employment on the terms and conditions set forth in this Agreement. This Agreement shall have an initial term of three years commencing as of November 1, 2023 (the “Start Date”) and ending on October 31, 2026 (the “Term”). This Agreement will automatically renew at the end of the initial Term and at the end of each subsequent Term, for a subsequent Term of one year unless either party gives written notice of non-renewal to the other at least six months prior to the expiration of the then current Term.

1.3Duties. As of the Start Date, Executive shall be employed as the President and Chief Operating Officer of the Company. As Chief Operating Officer, Executive shall report to the Chief Executive Officer of Bio-Techne and to the Chair of the Board of Directors, and shall assume primary responsibility for Bio-Techne’s regular operations.

Article II

COMPENSATION AND BENEFITS

2.1Base Salary. Bio-Techne will pay Executive as base compensation for services to be rendered hereunder an annual base salary as established by Bio-Techne from time to time, to be paid in accordance with the usual payroll practices of Bio-Techne. During the Transition Period, Executive’s annual base salary shall be $750,000, and upon Executive’s appointment as Chief Executive Officer, such annual base salary shall be increased to $900,000. Such annual base salary amount thereafter will be reviewed and adjusted by the Board or the Compensation Committee of the Board (the “Compensation Committee”) from time to time (but no less than annually) in its sole discretion. The annual base salary will be inclusive of all applicable income, Social Security, and other taxes and charges that are required by law to be withheld by Bio-Techne or under any applicable compensation or benefit plan or arrangement.

2.2Management Incentive Plan. Executive shall be eligible to receive an annual cash bonus commensurate with his position and level in accordance with Bio-Techne’s Management Incentive Plan or its equivalent (the “Management Incentive Plan”). The Management Incentive Plan contemplates an annual cash bonus based on a percentage of annual base salary and the achievement of annual performance targets, both of which are established and approved by the Board or the Compensation Committee from time to time. For the portion of each performance period during the Transition Period, Executive’s target annual bonus shall be equal to 100% of his annual base salary, prorated to reflect the portion of the applicable performance period during which Executive was employed in such position, and for the portion of each performance period following Executive’s appointment as Chief Executive Officer, such target annual bonus shall be increased to 110% of his annual base salary, prorated to reflect the portion of the applicable performance period during which Executive was employed in such position. After receipt of Bio-Techne’s final audit report of the applicable fiscal year, the Board or the Compensation Committee will determine and certify in writing the degree to which the annual performance targets have been achieved and calculate the portion of Executive’s annual cash bonus (if any) that will be paid. If earned, the annual cash bonus will be paid as soon as administratively practicable thereafter, but in no event later than would be permitted under the short-term deferral period defined by Section 409A of the Internal Revenue Code of 1986, as amended (“Code Section 409A”).

2.3Long-term Equity Awards. Executive will be eligible to participate in and receive periodic equity-based compensation awards commensurate with his position and level pursuant to any Bio-Techne equity-based compensation plan or program made available generally to executive officers; provided that the amount, timing, and other terms of any future awards shall be determined by the Board or the Compensation Committee, in its sole discretion.

CEO Employment Agreement (10/2023)

2.4Miscellaneous Benefits. Bio-Techne will provide Executive the following additional benefits:

(e)Reimbursement for the reasonable cost of an annual physical examination at a location of Executive’s choice, so long as Executive provides proper documentation of the cost of such physical examination.

2.5Other Compensation and Benefits. In addition to the compensation and benefits provided to Executive in Sections 2.1 through 2.4 hereof, Executive will be entitled to participate in other employee compensation and benefit plans from time to time established by Bio-Techne and made available generally to all employees of Bio-Techne to the extent that Executive’s age, tenure and title make him eligible to receive those benefits. With regard to all insured benefits to be provided to Executive, benefits shall be subject to due application by Executive. Bio-Techne has no obligation to pay insured benefits directly and such benefits are payable to Executive only by the insurers in accordance with their policies. Nothing in this Agreement is intended to or shall in any way restrict Bio-Techne’s right to amend, modify or terminate any of its benefits or benefit plans during the Term of this Agreement. Executive shall not be reimbursed for unused personal days or sick days upon his termination from employment regardless of the reason, whether voluntary or involuntary.

2.6Recoupment. The incentive compensation payable to Executive under any plan or agreement, including the amounts payable pursuant to Sections 2.2 and 2.3 hereof, shall be subject to reduction, cancellation, forfeiture or recoupment as and to the extent required by the applicable provisions of any law (including without limitation Section 10D of the Securities Exchange Act of 1934, as amended, Section 954 of the Xxxx-Xxxxx Xxxx Street Reform and Consumer Protection Act of 2010, and the rules and regulations promulgated thereunder), government regulation or stock exchange listing requirement, or clawback policy or provision implemented by Bio-Techne pursuant to such law, regulation or listing requirement.

Article V

TERMINATION BENEFITS

5.1Termination Without Cause or Resignation for Good Reason. Except as provided in Section 5.2, upon (i) a termination of Executive’s employment by Bio-Techne for a reason other than Cause, as defined in Section 4.1(g), but not including a termination due to Executive’s death or Disability, as provided in Sections 4.1(b) and (c), or (ii) Executive’s resignation for Good Reason, as defined below, Executive will receive the following payments:

(a)an amount equal to one (1) year of Executive’s then-current annual base salary (but not any cash or incentive bonus), payable to Executive on Bio-Techne’s regular payroll dates over the course of a one-year period beginning after expiration of any applicable rescission periods set forth in the Release and in no event later than 60 days following termination of employment,

(b)a prorated annual bonus for the annual performance period during which the termination occurs equal to the amount of the annual bonus that would have been payable if Executive’s employment had continued until the date on which annual bonuses for such performance period are payable to similarly situated employees of Bio-Techne, multiplied by a fraction, the numerator of which is the number of days in such performance period during which Executive was employed and the denominator of which is 365, and payable at the same time that annual bonuses are payable to similarly situated employees of Bio-Techne and

(c)continued payment by Bio-Techne of the employer portion of the premiums for the health, dental and vision coverage Executive was receiving under Bio-Techne’s group health, dental and vision plans as of the Termination Date for one (1) year (the payments in clauses (a), (b) and (c) hereinafter referred to as the “Termination Severance Payments”);

provided, however, that Executive shall be entitled to the Termination Severance Payments set forth in this Section 5.1 only if he executes within 60 days of termination of employment, does not rescind, and fully complies with a release agreement in a customary and mutually acceptable form (the “Release”). Notwithstanding the foregoing, if Bio-Techne determines, in its sole discretion, that payment of the COBRA premiums under this Section 5.1 would result in a violation of the nondiscrimination rules of Section 105(h)(2) of the Internal Revenue Code or any statute or

CEO Employment Agreement (10/2023)

regulation of similar effect, then in lieu of paying the COBRA premiums, Bio-Techne may instead elect to pay Executive on the first day of each month, a fully taxable cash payment equal to the employer portion of the COBRA premiums for that month, subject to applicable tax withholdings (the “Special Severance Payment”), for each remaining month during which Executive is entitled to receive payment of COBRA premiums under this Section 5.1. Executive may, but will not be obligated to, use the Special Severance Payment toward the cost of COBRA premiums.

As used in this Agreement, “Good Reason” means a good faith determination by Executive that any one or more of the following events have occurred; provided, however, that such event shall not constitute “Good Reason” if (x) Executive has expressly consented to such event in writing, (y) Executive fails to provide written notice to Bio-Techne within thirty (30) calendar days after Executive first becomes aware, or reasonably should have become aware, of the occurrence of such event, specifically describing such event, and Bio-Techne fails to remedy such event within thirty (30) calendar days after receipt of such notice, or (z) Executive fails to provide written notice of his decision to terminate within sixty (60) calendar days after the occurrence of such event:

(a)A material adverse change in Executive’s reporting responsibilities, titles or offices, or any removal of Executive from any of such positions, which has the effect of materially diminishing Executive’s responsibility or authority;

(b)A material reduction by Bio-Techne in Executive’s salary or annual bonus opportunity;

(c)A requirement imposed by Bio-Techne on Executive that results in Executive being based at a location that is outside a fifty (50) mile radius of Bio-Techne’s headquarters; or

(d)A material breach of this Agreement by Bio-Techne.

Termination for “Good Reason” shall not include Executive’s termination as a result of death, Disability, retirement or a termination for any reason other than the events specified in clauses (a) through (d) in this Section 5.1.

5.2Payment Upon Termination for Change in Control. If there is a Change in Control, as defined below, and either Executive either resigns for Good Reason or Executive’s employment is terminated by Bio-Techne or its successor without Cause (not including a termination due to Executive’s death or Disability, as provided in Sections 4.1(b) and (c)), and in either case such termination occurs upon the consummation of such Change in Control or within one (1) year thereafter, then in lieu of the severance benefits described in Section 5.1, Executive will receive the following:

(a)payment equal to two (2) years of his then-current annual base salary, payable in a lump sum payment within 60 days after the date of termination; plus

(b)payment equal to the pro-rated value of the greater of: (a) the target bonus for the fiscal year in which the termination occurs; or (b) the target bonus for the fiscal year

CEO Employment Agreement (10/2023)

in which the Change in Control occurs, if different, payable in a lump sum payment within 60 days after the date of termination; plus

(c)the automatic acceleration of any vesting requirements of the equity grants awarded to Executive by Bio-Techne during the Term of the Agreement; plus

(d)continued payment by Bio-Techne of the employer portion of the premiums for the health, dental and vision coverage Executive was receiving under Bio-Techne’s group health, dental and vision plans as of the Termination Date for two (2) years. Notwithstanding the foregoing, if Bio-Techne determines, in its sole discretion, that payment of the COBRA premiums under this Section 5.2 would result in a violation of the nondiscrimination rules of Section 105(h)(2) of the Internal Revenue Code or any statute or regulation of similar effect, payment of the COBRA benefits will be made as a Special Severance Payment as provided in Section 5.1 above.

The payments and benefits described in Section 5.2(a) through (d) above are hereinafter referred to as the “CIC Severance Payment.” However, Executive shall be entitled to the CIC Severance Payment set forth in this Section 5.2 only if he executes within 60 days of resignation or termination of employment, does not rescind, and fully complies with the Release.

For purposes of this Agreement, “Change in Control” shall mean the occurrence, in a single transaction or in a series of related transactions, of any one or more of the events described in subsections (a) through (c) below. For purposes of this definition, a person, entity or group shall be deemed to “Own,” to have “Owned,” to be the “Owner” of, or to have acquired “Ownership” of securities if such person, entity or group directly or indirectly, through any contract, arrangement, understanding, relationship or otherwise, has or shares voting power, which includes the power to vote or to direct the voting, with respect to such securities.

(a)Any person, entity or group becomes the Owner, directly or indirectly, of securities of Bio-Techne representing more than fifty percent (50%) of the combined voting power of Bio-Techne’s then outstanding securities other than by virtue of a merger, consolidation or similar transaction. Notwithstanding the foregoing, a Change in Control shall not be deemed to occur (A) on account of the acquisition of securities of Bio-Techne by an investor, any affiliate thereof or any other person, entity or group from Bio-Techne in a transaction or series of related transactions the primary purpose of which is to obtain financing for Bio-Techne through the issuance of equity securities or (B) solely because the level of Ownership held by any person, entity or group (the “Subject Person”) exceeds the designated percentage threshold of the outstanding voting securities as a result of a repurchase or other acquisition of voting securities by Bio-Techne reducing the number of shares outstanding, provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the acquisition of voting securities by Bio-Techne, and after such share acquisition, the Subject Person becomes the Owner of any additional voting securities that, assuming the repurchase or other acquisition had not occurred, increases the percentage of the then outstanding voting securities Owned by the Subject Person over the designated percentage threshold, then a Change in Control shall be deemed to occur;

CEO Employment Agreement (10/2023)

(b)There is consummated a merger, consolidation or similar transaction involving (directly or indirectly) Bio-Techne and, immediately after the consummation of such merger, consolidation or similar transaction, the stockholders of Bio-Techne immediately prior thereto do not Own, directly or indirectly, either (A) outstanding voting securities representing more than fifty percent (50%) of the combined outstanding voting power of the surviving entity in such merger, consolidation or similar transaction or (B) more than fifty percent (50%) of the combined outstanding voting power of the parent of the surviving entity in such merger, consolidation or similar transaction, in each case in substantially the same proportions as their Ownership of the outstanding voting securities of Bio-Techne immediately prior to such transaction; or

(c)There is consummated a sale, lease, exclusive license or other disposition of all or substantially all of the total gross value of the consolidated assets of Bio-Techne and its subsidiaries, other than a sale, lease, license or other disposition of all or substantially all of total gross value of the consolidated assets of Bio-Techne and its subsidiaries to an entity, more than fifty percent (50%) of the combined voting power of the voting securities of which are Owned by stockholders of Bio-Techne in substantially the same proportions as their Ownership of the outstanding voting securities of Bio-Techne immediately prior to such sale, lease, license or other disposition (for purposes of this Section 5.2(c), “gross value” means the value of the assets of Bio-Techne or the value of the assets being disposed of, as the case may be, determined without regard to any liabilities associated with such assets).

For the avoidance of doubt, the term Change in Control shall not include a sale of assets, merger or other transaction effected exclusively for the purpose of changing the domicile of Bio-Techne. To the extent required, the determination of whether a Change in Control has occurred shall be made in accordance with Code Section 409A and the regulations, notices and other guidance of general applicability issued thereunder.

5.25Change in Control Following Retirement. If there is a Change in Control following the termination of Executive’s employment by Executive as a result of Retirement, the vesting requirements of any unvested portion of any equity grants to Executive that have not expired, terminated, or been forfeited by their terms shall be automatically accelerated upon consummation of such Change in Control. For purposes of this Agreement, “Retirement” means termination of employment by Executive for any reason on or after Executive reached the age of 55 and has completed at least 5 years of continuous service with Bio-Techne and/or any affiliate; provided, however, that Executive shall be credited with continuous service only for periods during which Executive regularly works 20 or more hours per week. The terms of this Section 5.25 will survive the termination of this Agreement.

5.3Termination Due to Disability of Death. Upon a termination of Executive’s employment by Bio-Techne due to Executive’s Disability, as defined in Section 4.1(c), Executive shall receive a prorated annual bonus for the annual performance period during which the termination occurs equal to the amount of the annual bonus that would have been payable if Executive’s employment had continued until the date on which annual bonuses for such performance period are payable to similarly situated employees of Bio-Techne, multiplied by a fraction, the numerator of which is the number of days in such performance period during which

CEO Employment Agreement (10/2023)

Executive was employed and the denominator of which is 365, and payable at the same time that annual bonuses are payable to similarly situated employees of Bio-Techne.

5.4Offsets. All payments made to Executive pursuant to Section 5.1 or 5.2 will be reduced by amounts (A) required to be withheld in accordance with federal, state and local laws and regulations in effect at the time of payment, or (B) owed to Bio-Techne by Executive for any amounts advanced, loaned or misappropriated. Such offset will be made in the manner permitted by and will be subject to the limitations of all applicable laws, including but not limited to Code Section 409A, and the regulations, notices and other guidance of general applicability issued thereunder.

5.5No Other Payments. Except as provided in Section 5.1 and 5.2, including but not limited to if Executive is terminated with Cause or voluntarily terminates his employment at any time without Good Reason, Executive will not be entitled to any compensation or benefits other than that which was due to him as of the date of termination, regardless of any claim by Executive for compensation, salary, bonus, severance benefits or other payments.

Any dispute arising out of or relating to (i) this Agreement or the alleged breach of it, or the making of this Agreement, including claims of fraud in the inducement, or (ii) Executive’s application or candidacy for employment, employment and/or termination of employment with Bio-Techne including, but not limited to, any and all disputes, claims or controversies relating to discrimination, harassment, retaliation, wrongful discharge, and any and all other claims of any type under any federal or state constitution or any federal, state, or local statutory or common law shall be discussed between the disputing Parties in a good faith effort to arrive at a mutual settlement of any such controversy. If, notwithstanding, such dispute cannot be resolved, such dispute shall be settled by binding arbitration. Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction thereof. The arbitrator shall be a retired state or federal judge or an attorney who has practiced securities or business litigation for at least 10 years. If the Parties cannot agree on an arbitrator within 20 days, any Party may request that the chief judge of the District Court for Hennepin County, Minnesota, select an arbitrator. Arbitration will be conducted pursuant to the provisions of this Agreement, and the commercial arbitration rules of the American Arbitration Association, unless such rules are inconsistent with the provisions of this Agreement, but without submission of the dispute to such Association. Limited civil discovery shall be permitted for the production of documents and taking of depositions. Unresolved discovery disputes may be brought to the attention of the arbitrator who may dispose of such dispute. The arbitrator shall have the authority to award any remedy or relief that a court of this state could order or grant; provided, however, that punitive or exemplary damages shall not be awarded. The arbitrator may award to the prevailing Party, if any, as determined by the arbitrator, all of its costs and fees, including the arbitrator’s fees, administrative fees, travel expenses, out-of-pocket expenses and reasonable attorneys’ fees. Unless otherwise agreed by the Parties, the place of any arbitration proceedings shall be Hennepin County, Minnesota. This agreement to arbitrate does not include worker’s compensation claims, claims for

unemployment compensation, or any injunctive or other relief to which the Bio-Techne may be entitled in accordance with Section 3 above.

MISCELLANEOUS PROVISIONS

7.1Modifications. This Agreement supersedes all prior agreements and understandings between the Parties relating to the employment of Executive by Bio-Techne and it may not be changed or terminated orally. No modification, termination, or attempted waiver of any of the provisions of this Agreement will be valid unless in writing signed by the Party against whom the same is sought to be enforced.

7.2Binding Effect. The breach by Bio-Techne of any other agreement or instrument between Bio-Techne and Executive will not excuse or waive Executive’s performance under, or compliance with, this Agreement.

7.3Governing Law. This Agreement will be governed by and construed in accordance with the laws of the State of Minnesota, without regard to conflicts of law principles that would require the application of any other law.

7.4Successors and Assigns. This Agreement is personal to Executive and Executive may not assign or transfer any part of his rights or duties hereunder, or any compensation due to him hereunder, to any other person. This Agreement may be assigned by Bio-Techne and Executive expressly consents to the assignment of any and all obligations of Executive under this Agreement.

7.6No Conflicting Obligations. Executive represents and warrants to Bio-Techne that he is not under, or bound to be under in the future, any obligation to any person, firm, or corporation that is or would be inconsistent or in conflict with this Agreement or would prevent, limit, or impair in any way the performance by Executive of Executive’s obligations hereunder. If Executive possesses any information that he knows or should know is considered by any third party, such as a former employer of Executive’s to be confidential, trade secret, or otherwise proprietary, Executive shall not disclose such information to Bio-Techne or use such information to benefit Bio-Techne in any way.

7.7Waivers. The failure of any Party to require the performance or satisfaction of any term or obligation of this Agreement, or the waiver by any Party of any breach of this Agreement, will not prevent subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach.

7.8Severability. In the event that any provision hereof is held invalid or unenforceable by a court of competent jurisdiction, Bio-Techne and Executive agree that that part should modified by the court to make it enforceable to the maximum extent possible. If the part cannot be

CEO Employment Agreement (10/2023)

modified, then that part may be severed and the other parts of this Agreement shall remain enforceable.

7.9Code Section 409A.

(a)Notwithstanding any other provision of this Agreement to the contrary, the Parties to this Agreement intend that this Agreement will satisfy the applicable requirements, if any, of Code Section 409A in a manner that will preclude the imposition of additional taxes and interest imposed under Code Section 409A. The Parties agree that this Agreement will be read or amended (as determined by Bio-Techne in its sole discretion) to the extent necessary to comply with Code Section 409A, as amended from time to time, and the notices and other guidance of general applicability issued thereunder. For purposes of Code Section 409A, each payment made under this Agreement will be treated as a separate payment. In no event may Executive, directly or indirectly, designate the calendar year of payment.

(b)All reimbursements provided under this Agreement will be made or provided in accordance with the requirements of Code Section 409A, including, where applicable, the requirement that (i) any reimbursement is for expenses incurred during Executive’s lifetime (or during a shorter period of time specified in this Agreement), (ii) the amount of expenses eligible for reimbursement during a calendar year may not affect the expenses eligible for reimbursement in any other calendar year, (iii) the reimbursement of an eligible expense will be made on or before the last day of the calendar year following the year in which the expense is incurred, and (iv) the right to reimbursement is not subject to liquidation or exchange for another benefit.

(c)Further, if any of the payments described in this Agreement are subject to the requirements of Code Section 409A and Bio-Techne determines that Executive is a “specified employee” as defined in Code Section 409A as of the date of Executive’s termination of employment (which will have the same meaning as “separation from service” as defined in Code Section 409A), all or a portion of such payments will not be paid or commence earlier than the first day of the seventh month following the date of Executive’s termination of employment (or, if earlier, the date of Executive’s death), but only to the extent such delay is required for compliance with Code Section 409A.

7.10Notices. All notices given or made pursuant to this Agreement shall be in writing and shall be deemed effectively given, delivered and received (A) upon personal delivery to the Party to be notified; (B) five (5) calendar days after having been sent by registered or certified mail, return receipt requested, postage prepaid; or (C) one (1) business day after the business day of deposit with a nationally recognized overnight courier, specifying next-day delivery, with written verification of receipt.

7.11Construction. The Parties agree that the terms and provisions of this Agreement embody their mutual intent, each Party has had the opportunity to negotiate its provisions and contribute to its drafting, and therefore, it is not to be construed more liberally in favor of, or more strictly against, any Party hereto.

7.12Counterparts. This Agreement may be executed in one or more counterparts, each of which will be deemed to be an original of this Agreement and all of which, when taken together, will be deemed to constitute one and the same agreement. Electronically transmitted (e.g., by facsimile or pdf) signed copies of this Agreement shall be deemed to be original signed versions of this Agreement.

7.13Section 280G. Notwithstanding anything to the contrary contained in this Agreement, to the extent that any of the payments and benefits provided for under this Agreement or any other agreement or arrangement between the Executive and the Bio-Techne (collectively, the “Payments”) constitute a “parachute payment” within the meaning of Section 280G of the Code and, but for this Section 7.13, would be subject to the excise tax imposed by Section 4999 of the Code, then the Payments shall be payable either (i) in full or (ii) as to such lesser amount which would result in no portion of such Payments being subject to excise tax under Section 4999 of the Code; whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the excise tax imposed by Section 4999, results in the Executive’s receipt on an after-tax basis, of the greatest amount of economic benefits under this Agreement, notwithstanding that all or some portion of such benefits may be taxable under Section 4999 of the Code. Unless the Executive and Bio-Techne otherwise agree in writing, any determination required under this Section 7.13 shall be made in writing by Bio-Techne’s independent public accountants (the “Accountants”), whose reasonable determination shall be conclusive and binding upon Executive and Bio-Techne for all purposes. For purposes of making the calculations required by this Section 7.13, the Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of the Sections 280G and 4999 of the Code. Executive and Bio-Techne shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination under this Section 7.13. The Accountants will provide its calculations, together with detailed supporting documentation, to the Company and Executive as soon as practicable following its engagement. If a reduction in Payments is required by this provision and none of the Payments constitute “non-qualified deferred compensation” subject to Code Section 409A, then the reduction will occur in the manner Executive elects in writing prior to the date of payment. If any Payment constitutes “non-qualified deferred compensation” subject to Code Section 409A or if Executive fails to elect an order, then the Payments to be reduced will be determined in a manner which has the least economic cost to Executive and, to the extent the economic cost is equivalent, will be reduced in the inverse order of when payment would have been made to Executive, until the reduction is achieved.
