 Exhibit 10.2 

SEVERANCE AND 
 CHANGE OF
CONTROL AGREEMENT 
 CHANGE OF CONTROL AGREEMENT by and between HOLOGIC, INC., a Delaware corporation (the “Company”), and
Eric Compton (the “Executive”), dated as of March 9, 2014. 
 WHEREAS, the Board of Directors of the Company (the
“Board”), has determined that it is in the best interests of the Company and its shareholders to assure that the Company will have the continued dedication of the Executive, notwithstanding the possibility, threat, or occurrence of a
Change of Control (as defined below) of the Company. The Board believes it is imperative to diminish the inevitable distraction of the Executive by virtue of the personal uncertainties and risks created by a pending or threatened Change of Control
and to encourage the Executive’s full attention and dedication to the Company currently and in the event of any threatened or pending Change of Control, and to provide the Executive with compensation and benefits arrangements upon a Change of
Control which ensure that the compensation and benefits expectations of the Executive will be satisfied and which are competitive with those of other corporations; 

WHEREAS, the Executive was hired as Chief Operating Officer of the Company with a start date of April 14, 2014; 

WHEREAS, in recognition of the Executive’s hiring as Chief Operating Officer, the Company and Executive now desire to enter into this
Severance and Change of Control Agreement, which is consistent with the change of control and severance protection provided to the Company’s most senior officers (the “Agreement”). 

NOW, THEREFORE, in consideration of the mutual covenants and agreements hereinafter set forth, the parties hereto, each intending to be
legally bound, do hereby agree as follows: 
 1. Certain Definitions. 

(a) The “Effective Date” shall be the first date during the “Change of Control Period” (as defined in Section 1(b))
on which a Change of Control occurs. Anything in this Agreement to the contrary notwithstanding, if the Executive’s employment with the Company is terminated or the Executive ceases to be an officer of the Company prior to the date on which a
Change of Control occurs, and it is reasonably demonstrated that such termination of employment (1) was at the request of a third party who has taken steps reasonably calculated to effect the Change of Control or (2) otherwise arose in
connection with or in anticipation of the Change of Control, then for all purposes of this Agreement the “Effective Date” shall mean the date immediately prior to the date of such termination of employment. If prior to the Effective Date,
the Executive’s employment with the Company terminates, then the Executive shall have no further rights under this Agreement, except with respect to benefits under Section 6(e), if applicable, or unless such termination of Employment was
in anticipation of the Change of Control in which case the termination shall be deemed to have occurred after the consummation of the Change of Control. 

 (b) The “Change of Control Period” is the period commencing on the date hereof and
ending on December 31, 2016; provided, that commencing on December 31, 2014 and each December 31 thereafter (each such date to be referred to as the “Renewal Date”), the term of this Agreement shall automatically be
extended, without any further action by the Company or the Executive, so as to terminate three years from such Renewal Date; provided, however that if the Company shall give notice in writing to the Executive at least thirty (30) days prior to
a Renewal Date (the “Pending Renewal Date”), stating that the Change of Control Period shall not be extended, then the Change of Control Period shall expire two years from the Pending Renewal Date. 

2. Change of Control. For the purpose of this Agreement, a “Change of Control” shall mean: 

(a) The acquisition by any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act
of 1934, as amended (the “Exchange Act”)) of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 30% or more of the Voting Stock of the Company; provided, however, that any acquisition by the
Company or its subsidiaries, or any employee benefit plan (or related trust) of the Company or its subsidiaries of 30% or more of Voting Stock shall not constitute a Change in Control; and provided, further, that any acquisition by a corporation
with respect to which, following such acquisition, more than 50% of the Voting Stock of such corporation, is then beneficially owned, directly or indirectly, by all or substantially all of the individuals and entities who were the beneficial owners
of the Voting Stock immediately prior to such acquisition in substantially the same proportion as their ownership, immediately prior to such acquisition, of the Voting Stock, shall not constitute a Change in Control; or 

(b) Any transaction which results in the Continuing Directors (as defined in the Certificate of Incorporation of the Company) constituting
less than a majority of the Board of Directors of the Company (the “Board”); or 
 (c) The consummation of (i) a Merger with
respect to which all or substantially all of the individuals and entities who were the beneficial owners of the Voting Stock immediately prior to such Merger do not, following such Merger, beneficially own, directly or indirectly, more than 50% of
the Voting Stock of the corporation resulting from the Merger (the “Resulting Corporation”) as a result of the individuals’ and entities’ shareholdings in the Company immediately prior to the consummation of the Merger,
(ii) a complete liquidation or dissolution of the Company or (iii) the sale or other disposition of all or substantially all (as defined under Delaware General Corporation Law) of the assets of the Company excluding a sale or other
disposition of assets to a subsidiary of the Company. For purposes of this Agreement “Merger” means a reorganization, merger or consolidation involving the Company, including without limitation as a parent of a direct or indirect
subsidiary of the Company effecting such transaction 
 Anything in this Agreement to the contrary notwithstanding, if an event that would,
but for this paragraph, constitute a Change of Control results from or arises out of a purchase or other acquisition of the Company, directly or indirectly, by a corporation or other entity in which the Executive has a greater than ten percent
(10%) direct or indirect equity interest, such event shall not constitute a Change of Control.

 3. Employment Period. Subject to the terms and conditions hereof, the Company hereby agrees to
continue the Executive in its employ, and the Executive hereby agrees to remain in the employ of the Company, for the period commencing on the Effective Date and ending on the last day of the thirty-sixth month following the month in which the
Effective Date occurs (the “Employment Period”). 
 4. Terms of Employment. 

(a) Position and Duties. 

(i) During the Employment Period, (A) the Executive’s position (including status, offices, titles and reporting
requirements), authority, duties and responsibilities shall be at least commensurate in all material respects with the most significant of those held, exercised and assigned at any time during the 90-day period immediately preceding the Effective
Date and (B) the Executive’s services shall be performed at the location where the Executive was employed immediately preceding the Effective Date or any office or location less than 35 miles from such location. 

(ii) During the Employment Period, and excluding any periods of vacation and sick leave to which the Executive is entitled, the
Executive agrees to devote his full business time to the business and affairs of the Company and, to the extent necessary to discharge the responsibilities assigned to the Executive hereunder, to use the Executive’s reasonable best efforts to
perform faithfully and efficiently such responsibilities. During the Employment Period it shall not be a violation of this Agreement for the Executive to (A) serve on corporate, civic or charitable boards or committees, (B) deliver
lectures, fulfill speaking engagements or teach at educational institutions and (C) manage personal investments, so long as such activities do not significantly interfere with the performance of the Executive’s responsibilities as an
employee of the Company in accordance with this Agreement. It is expressly understood and agreed that to the extent that any such activities have been conducted by the Executive prior to the Effective Date, the continued conduct of such activities
(or the conduct of activities similar in nature and scope thereto) subsequent to the Effective Date. 
 (b) Compensation. 

(i) Base Salary. During the Employment Period, the Executive shall receive an annual base salary (“Annual Base
Salary”), which shall be paid at a monthly rate, at least equal to twelve times the highest monthly base salary paid or payable to the Executive by the Company and its affiliated companies in respect of the twelve-month period immediately
preceding the month in which the Effective Date occurs. During the Employment Period, the Annual Base Salary shall be reviewed at least annually and shall be increased at any time and from time to time as shall be substantially consistent with
increases in base salary awarded in the ordinary course of business to other peer 

  
 -3- 

 
executives of the Company and its affiliated companies. Any increase in Annual Base Salary shall not serve to limit or reduce any other obligation to the Executive under this Agreement. Annual
Base Salary shall not be reduced after any such increase and the term Annual Base Salary as utilized in this Agreement shall refer to Annual Base Salary as so increased. As used in this Agreement, the term “affiliated companies” includes
any company controlled by, controlling or under common control with the Company. 
 (ii) Annual Bonus. In addition to Annual Base Salary, the
Executive shall be awarded, for each fiscal year during the Employment Period, an annual cash bonus (the “Annual Bonus”; which shall include, without limitation, any other annual cash bonus plan or program provided to Executive such as the
Short Term Incentive Plan or any other similar plan, but shall not include any cash sign-on, relocation, retention or other special bonus or payments. ) in cash at least equal to the greater of (a) the average (annualized for any fiscal year
consisting of less than twelve full months or with respect to which the Executive has been employed by the Company for less than twelve full months) bonus (the “Average Annual Bonus”) paid or that has been earned and accrued, but unpaid to
the Executive by the Company and its affiliated companies in respect of the three fiscal years immediately preceding the fiscal year in which the Effective Date occurs, (b) the Annual Bonus paid for the fiscal year immediately preceding the
Effective Date, or (c) the target bonus associated with the Company achieving its 100 percent target payout level as determined in accordance with the terms of the Company’s bonus plans for senior executives for the fiscal year immediately
preceding the Effective Date (the “Target Bonus”; the greater of clauses (a), (b) or (c) to be referred to as the “Highest Annual Bonus”) and shall not be reduced for the application of the Compensation Committee’s
discretion to reduce such bonus or bonus funding, or increased to reflect additional amounts that may be paid or payable if the Company exceeds target. Each such Annual Bonus shall be paid no later than the 15th day of the third month of the fiscal
year next following the fiscal year for which the Annual Bonus is awarded, unless the Executive shall elect to defer the receipt of such Annual Bonus pursuant to any nonqualified plan of the Company. Notwithstanding anything herein to the contrary,
any portion of Annual Base Salary or Annual Bonus electively deferred by the Executive pursuant to a qualified or a non-qualified plan including, but not limited to, the Hologic, Inc. Deferred Compensation Plan or any successor thereto
(“DCP”) shall be included in determining the Annual Base Salary, Annual Bonus and the Average Annual Bonus. If the fiscal year of any successor to this Agreement, as described by Section 11(c) herein, is different than the
Company’s fiscal year at the time of the Change of Control, then the Executive shall be paid (i) the Annual Bonus that would have been paid upon the end of Company’s fiscal year ending after the Change of Control, and (ii) a
pro-rata Annual Bonus for any months of service performed following the end of the Company’s fiscal year, but prior to the first day of the successor’s fiscal year immediately following the Change of Control. The Annual Bonuses thereafter
shall be based on the successor’s first full fiscal year beginning after the Change of Control and successive fiscal years thereafter. “Pro Rata Bonus” shall mean an amount equal to the Bonus Amount (average of the Annual Bonuses paid
or that has been earned and accrued, but unpaid during the three full fiscal years ended prior to the Date of Termination) multiplied by a fraction the numerator of which is the number of months worked in the fiscal year through the Date of
Termination and the denominator of which is 12. Any partial months shall be rounded to the nearest whole number using normal mathematical convention.

 (iii) Incentive, Savings and Retirement Plans. In addition to Annual Base
Salary and Annual Bonus payable as hereinabove provided, the Executive shall be entitled to participate during the Employment Period in all incentive, savings and retirement plans, practices, policies and programs applicable to other peer executives
of the Company and its affiliated companies, but in no event shall such plans practices, policies and programs provide the Executive with incentive, savings and retirement benefits opportunities, in each case, less favorable, in the aggregate, than
the most favorable of those provided by the Company and its affiliated companies for the Executive under such plans, practices, policies and programs as in effect at any time during the one-year immediately preceding the Effective Date, or, if more
favorable to the Executive, those provided generally at any time after the Effective Date to other peer executives of the Company and its affiliated companies. 

(iv) Welfare Benefit Plans. During the Employment Period, the Executive and/or the Executive’s family, as the case
may be, shall be eligible for participation in and shall receive all benefits under welfare benefit plans, practices, policies and programs provided by the Company and its affiliated companies (including, without limitation, medical, prescription,
dental, disability, salary continuance, employee life, group life, accidental death and travel accident insurance plans and programs) and applicable to other peer executives of the Company and its affiliated companies, but in no event shall such
plans, practices, policies and programs provide benefits which are less favorable, in the aggregate, than the most favorable of such plans, practices, policies and programs in effect at any time during the one-year period immediately preceding the
Effective Date, or, if more favorable to the Executive, those provided generally at any time after the Effective Date to other peer executives of the Company and its affiliated companies. 

(v) Expenses. During the Employment Period, the Executive shall be entitled to receive prompt reimbursement for all
reasonable expenses incurred by the Executive upon submission of appropriate accountings in accordance with the most favorable policies, practices and procedures of the Company and its affiliated companies in effect at any time during the one-year
period immediately preceding the Effective Date or, if more favorable to the Executive, as in effect at any time thereafter with respect to other peer executives of the Company and its affiliated companies. 

(vi) Fringe Benefits. During the Employment Period, the Executive shall be entitled to fringe benefits in accordance
with the most favorable plans, practices, programs and policies of the Company and its affiliated companies in effect at any time during the one-year period immediately preceding the Effective Date or, if more favorable to the Executive, as in

 (vii)
Office and Support Staff. During the Employment Period, the Executive shall be entitled to an office or offices of a size and with furnishings and other appointments, and to exclusive personal secretarial and other assistance, at least equal
to the most favorable of the foregoing provided to the Executive by the Company and its affiliated companies at any time during the one-year period immediately preceding the Effective Date or, if more favorable to the Executive, as provided at any
time thereafter with respect to other peer executives of the Company and its affiliated companies.

 (viii) Vacation. During the Employment Period, the Executive shall be
entitled to paid vacation of at least five (5) weeks and in accordance with the most favorable plans, policies, programs and practices of the Company and its affiliated companies as in effect at any time during the one-year period immediately

5. Termination of Employment. 

(a) Death or Disability. The Executive’s employment shall terminate automatically upon the Executive’s death during the
Employment Period. If the Company determines in good faith that the Disability of the Executive has occurred during the Employment Period (pursuant to the definition of “Disability” set forth below), it may give to the Executive written
notice in accordance with Section 13(b) of this Agreement of its intention to terminate the Executive’s employment. In such event, the Executive’s employment with the Company shall terminate effective on the 30th day after receipt of
such notice by the Executive (the “Disability Effective Date”), provided that, within the 30 days after such receipt, the Executive shall not have returned to full-time performance of the Executive’s duties. For purposes of this
Agreement, “Disability” means the absence of the Executive from the Executive’s duties with the Company on a full-time basis for 180 consecutive business days as a result of incapacity due to mental or physical illness which is

(b) Cause. The Company may terminate the Executive’s employment during the Employment Period for “Cause”. For purposes
of this Agreement, “Cause” means (i) an act or acts of personal dishonesty taken by the Executive and intended to result in substantial personal enrichment of the Executive at the expense of the Company, (ii) repeated violations
by the Executive of the Executive’s obligations under Section 4(a) of this Agreement (other than as a result of incapacity due to physical or mental illness) which are demonstrably willful and deliberate on the Executive’s part, which
are committed in bad faith or without reasonable belief that such violations are in the best interests of the Company and which are not remedied in a reasonable period of time after receipt of written notice from the Company or (iii) the
conviction of the Executive of a felony involving moral turpitude. The Company shall provide the Executive with 30 days written notice of any determination of Cause and provide the Executive, for a period of 30 days following such notice, with the
opportunity to appear before the Board, with or without legal representation, to present arguments and evidence on his behalf and following such presentation to the Board, the Executive may only be terminated for Cause if the Board (excluding the
Executive if he is a member of the Board), by unanimous consent reasonably determines in good faith that his actions did, in fact, constitute for Cause.

 (c) Good Reason. The Executive’s employment may be terminated during the Employment
Period by the Executive for Good Reason. For purposes of this Agreement, “Good Reason” means:

diminution in the Executive’s base compensation; 
 (ii) A material diminution in the Executive’s authority, duties
and responsibilities as in effect immediately prior to the Change of Control or, if applicable, the Date of Termination; 

(iii) A material diminution in the authority, duties and responsibilities of the supervisor to whom the Executive is required
to report as in effect immediately prior to the Change of Control or, if applicable, the Date of Termination; 
 (iv) A
material change in the geographic location in which Executive’s principal office was located immediately prior to the Change of Control or, if applicable, the Date of Termination; 

(v) A material diminution in the budget over which the Executive had authority immediately prior to the of the Change of
Control or, if applicable, the Date of Termination; 
 (vi) Any other action or inaction that constitutes a material breach
by the Company of this Agreement or any other agreement under which the Executive provides services; 
 provided, however, that Good Reason
shall not exist unless the Executive has given written notice to the Company within ninety (90) days of the initial existence of the Good Reason event or condition(s) giving specific details regarding the event or condition; and unless the
Company has had at least thirty (30) days to cure such Good Reason event or condition after the delivery of such written notice and has failed to cure such event or condition to the reasonable satisfaction of the Executive within such thirty
(30) day cure period. The Executive’s separation from service must occur not more than one year following the initial existence of one or more of the conditions constituting Good Reason. 

(d) Notice of Termination. Any termination by the Company for Cause or by the Executive for Good Reason shall be communicated by Notice
of Termination to the other party hereto given in accordance with Section 13(b) of this Agreement. For purposes of this Agreement, a “Notice of Termination” means a written notice which (i) indicates the specific termination
provision in this Agreement relied upon, (ii) to the extent applicable, sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive’s employment under the provision so indicated
and (iii) if the Date of Termination (as defined below) is other than the date of receipt of such notice, specifies the termination date (which date shall be not more than fifteen days after the giving of such notice). The failure by the
Executive or the Company to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Good Reason or Cause shall not waive any right of the Executive or the Company hereunder or preclude the Executive or the
Company from asserting such fact or circumstance in enforcing the Executive’s or the Company’s rights hereunder. 

  
 -7- 

 (e) Date of Termination. “Date of Termination” means the date of receipt of the
Notice of Termination or any later date (taking into account any applicable notice and cure period) specified therein, as the case may be; provided however, that (i) if the Executive’s employment is terminated by the Company other than for
Cause, death or Disability, the Date of Termination shall be the date on which the Company notifies the Executive of such termination, and (ii) if the Executive’s employment is terminated by reason of death or Disability, the Date of
Termination shall be the date of death of the Executive or the Disability Effective Date, as the case may be. 
 6. Obligations of the Company upon
Termination.

the Employment Period, this Agreement shall terminate without further obligations to the Executive’s legal representatives under this Agreement, other than for (i) payment of the sum of the following amounts: (A) the Executive’s
Annual Base Salary through the Date of Termination to the extent not theretofore paid, (B) the product of (I) the Highest Annual Bonus and (II) a fraction, the numerator of which is the number of days in the current fiscal year through the

Company and its affiliated companies as in effect and applicable generally to other peer executives and their families during the one year period immediately preceding the Effective Date or, if more favorable to the Executive, as in effect at any
time thereafter with respect to other peer executives of the Company and its affiliated companies and their families (such continuation of such benefits for the applicable period herein set forth and such transfer of the Individual Policy shall be
hereinafter referred to as “Welfare Benefit Continuation”; for purposes of determining eligibility of the Executive for retiree benefits pursuant to such plans, practices, programs and policies, the Executive shall be considered to have
remained employed until the end of the Employment Period and to have retired on the last day of such period), and (iv) payment to the Executive’s estate or beneficiary, as applicable, in a lump sum in cash within 30 days of the Date of

Executive’s family shall be entitled to receive benefits at least equal to the

most favorable benefits provided by the Company and any of its affiliated companies to surviving families of peer executives of the Company and such affiliated companies under such plans,
programs, practices and policies relating to family death benefits, if any, as in effect with respect to other peer executives and their families at any time during the one year period immediately preceding the Effective Date or, if more favorable

(b) Disability. If the Executive’s employment is terminated by reason of the Executive’s Disability during the Employment

(d) Termination Following a Change of Control by the Company without Cause or by the Executive for Good Reason. If during the
Employment Period the Executive is terminated by the Company without Cause or he resigns for Good Reason, then the Company shall pay the Executive the following:

 (i) the Company shall pay the
Executive all Accrued Obligations;

(g) Other Severance Benefits. The severance pay and benefits provided for in Section 6(e) shall be in lieu of any other severance
or termination pay to which the Executive may be entitled under any Company severance or termination plan, program, practice or arrangement. The Executive’s entitlement to any other compensation or benefits shall be determined in accordance

 7. Non-exclusivity of Rights. Except as provided in Section 6, nothing in this Agreement shall
prevent or limit the Executive’s continuing or future participation in any benefit, bonus, incentive or other plans, programs, policies or practices, provided by the Company or any of its affiliated companies and for which the Executive may
qualify, nor shall anything herein limit or otherwise affect such rights as the Executive may have under any other agreements with the Company or any of its affiliated companies. Amounts which are vested benefits or which the Executive is otherwise
entitled to receive under any plan, policy, practice or program of the Company or any of its affiliated companies at or subsequent to the Date of Termination shall be payable in accordance with such plan, policy, practice or program except as
explicitly modified by this Agreement. 
 8. Full Settlement. 

(a) The Company’s obligation to make the payments provided for in this Agreement and otherwise to perform its obligations hereunder shall
not be affected by any set-off, counterclaim, recoupment, defense or other claim, right or action which the Company may have against the Executive or others. In no event shall the Executive be obligated to seek other employment or take any other
action by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement and, except as provided in Section 6(d)(ii), such amounts shall not be reduced whether or not the Executive obtains other
employment. 
 (b) Prior to the occurrence of a Change of Control, the Company agrees to reimburse the Executive for all legal fees and
expenses which the Executive may reasonably incur as a result of any contest by the Company, the Executive or others of the validity or enforceability of, or liability under, any provision of this Agreement or any guarantee of performance thereof,
if the Executive prevails in such contest. Following a Change of Control, the Company agrees to pay promptly as incurred, to the full extent permitted by law, all legal fees and expenses which the Executive may reasonably incur as a result of any
contest (regardless of the outcome thereof) by the Company, the Executive or others of the validity or enforceability of, or liability under, any provision of this Agreement or any guarantee of performance thereof. 

(c) If there shall be any dispute between the Company and the Executive (i) in the event of any termination of the Executive’s
employment by the Company, whether such termination was for Cause, or (ii) in the event of any termination of employment by the Executive, whether Good Reason existed, then, unless and until there is a final, nonappealable judgment by a court
of competent jurisdiction declaring that such termination was for Cause or that the determination by the Executive of the existence of Good Reason was not made in good faith, the Company shall pay all amounts, and provide all benefits, to the
Executive and/or the Executive’s family or other beneficiaries, as the case may be, that the Company would be required to pay or provide pursuant to Section 6(d) as though such termination were by the Company without Cause, or by the
Executive with Good Reason; provided, however, that the Company shall not be required to pay any disputed amount pursuant to this paragraph except upon receipt of an undertaking by or on behalf of the Executive to repay all such amounts to which the
Executive is ultimately adjudged by such court not to be entitled. 

  
 -11- 

 9. 280G Protection. 

(a) In the event that the Executive shall become entitled to payment and/or benefits provided by this Agreement or any other amounts in the
“nature of compensation” (whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement with the Company, any person whose actions result in a change of ownership or effective control covered by
Section 280G(b)(2) of the Internal Revenue Code (the “Code”) or any person affiliated with the Company or such person) as a result of such change in ownership or effective control (collectively the “Company Payments”), and
such Company Payments will be subject to the tax (the “Excise Tax”) imposed by Section 4999 of the Code (and any similar tax that may hereafter be imposed by any taxing authority) the Company shall pay to the Executive the greater of
the following, whichever gives the Executive the highest net after-tax amount (after taking into account federal, state, local and social security taxes at the maximum marginal rates) (x) the Company Payments or (y) one dollar less than
the amount of the Company Payments that would subject the Executive to the Excise Tax. In the event that the Company Payments are required to be reduced pursuant to the foregoing sentence, then the Company Payments shall be reduced as mutually
agreed between the Company and the Executive or, in the event the parties cannot agree, in the following order (1) any lump sum severance based on Base Salary or Annual Bonus, (2) any other cash amounts payable to the Executive,
(3) any benefits valued as parachute payments; and (4) acceleration of vesting of any equity. 
 (b) For purposes of determining
whether any of the Company Payments will be subject to the Excise Tax and the amount of such Excise Tax, (x) the Company Payments shall be treated as “parachute payments” within the meaning of Section 280G(b)(2) of the Code, and
all “parachute payments” in excess of the “base amount” (as defined under Code Section 280G(b)(3) of the Code) shall be treated as subject to the Excise Tax, unless and except to the extent that, in the opinion of the
Company’s independent certified public accountants appointed prior to any change in ownership (as defined under Section 280G(b)(2) of the Code) or tax counsel selected by such accountants or the Company (the “Accountants”) such
Company Payments (in whole or in part) either expressly do not constitute “parachute payments,” represent reasonable compensation for services actually rendered within the meaning of Section 280G(b)(4) of the Code in excess of the
“base amount” or are otherwise not subject to the Excise Tax, and (y) the value of any non-cash benefits or any deferred payment or benefit shall be determined by the Accountants. All determinations hereunder shall be made by the
Accountants which shall provide detailed supporting calculations both to the Company and the Executive at such time as it is requested by the Company or the Executive. If the Accountants determine that payments under this Agreement must be reduced
pursuant to this paragraph, they shall furnish the Executive with a written opinion to such effect. The determination of the Accountants shall be final and binding upon the Company and the Executive. 

(c) In the event of any controversy with the Internal Revenue Service (or other taxing authority) with regard to the Excise Tax, the Executive
shall permit the Company to control issues related to the Excise Tax (at its expense), provided that such issues do not potentially materially adversely affect the Executive, but the Executive shall control any other issues. In the event the issues
are interrelated, the Executive and the Company shall in good faith cooperate so as not to jeopardize resolution of either issue, but if the parties cannot agree the Executive shall 

  
 -12- 

 
make the final determination with regard to the issues. In the event of any conference with any taxing authority regarding the Excise Tax or associated income taxes, the Executive shall permit
the representative of the Company to accompany the Executive, and the Executive and the Executive’s representative shall cooperate with the Company and its representative. 

10. Confidential Information. The Executive shall hold in a fiduciary capacity for the benefit of the Company all secret or confidential
information, knowledge or data relating to the Company or any of its affiliated companies, and their respective businesses, which shall have been obtained by the Executive during the Executive’s employment by the Company or any of its
affiliated companies and which shall not be or become public knowledge (other than by acts by the Executive or representatives of the Executive in violation of this Agreement). After termination of the Executive’s employment with the Company,
the Executive shall not, without the prior written consent of the Company or as may otherwise be required by law or legal process, communicate or divulge any such information, knowledge or data to anyone other than the Company and those designated
by it. In no event shall an asserted violation of the provisions of this Section 10 constitute a basis for deferring or withholding any amounts otherwise payable to the Executive under this Agreement. 

11. Successors. 
 (a) This
Agreement is personal to the Executive and without the prior written consent of the Company shall not be assignable by the Executive otherwise than by will or the laws of descent and distribution. This Agreement shall inure to the benefit of and be
enforceable by the Executive’s legal representatives. 
 (b) This Agreement shall inure to the benefit of and be binding upon the
Company and its successors and assigns. 
 (c) The Company will require any successor (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it
if no such succession had taken place. The Company shall provide written evidence to the Executive to document compliance with the foregoing sentence within ten (10) business days of the Effective Date. As used in this Agreement,
“Company” shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid which assumes and agrees to perform this Agreement by operation of law, or otherwise. In addition, the Executive shall be
entitled, upon exercise of any outstanding stock options or stock appreciation rights of the Company, to receive in lieu of shares of the Company’s stock, shares of such stock or other securities of such successor as the holders of shares of
the Company’s stock received pursuant to the terms of the merger, consolidation or sale. 
 12. Compliance With Section 409A of the Internal
Revenue Code. To the extent applicable, it is intended that this Agreement comply with the provisions of Section 409A of the Code (hereinafter referred to as “Section 409A”). This Agreement shall be administered in a manner
consistent with its intent, and any provision that would cause the Agreement to fail to 

  
 -13- 

 
satisfy Section 409A shall have no force and effect until amended to comply with Section 409A. Notwithstanding any provision of this Agreement to the contrary, in the event any payment
or benefit hereunder is determined to constitute non-qualified deferred compensation subject to Section 409A, then to the extent necessary to comply with Section 409A, such payment or benefits shall not be made, provided or commenced until
six (6) months after the Executive’s “separation from service” as such phrase is defined for the purposes of Section 409A. 
 13.
Release. The Executive agrees that, with the exception of the Accrued Obligations due to him in accordance with the terms hereunder, that the payment of any severance under this Agreement to the Executive by the Company, is subject to
and conditioned on Executive executing a general release of the Company in a form and scope determined by the Company in its sole discretion (the “Release Agreement”), without Executive revoking such Release Agreement within fifty-two
(52) days of the Date of Termination (the “Consideration Period”) and provided that (a) if the Date of Termination occurs in one calendar year and the Consideration Period (including the payment date) expires during the following
calendar year, then notwithstanding anything herein to the contrary, the payments of severance under Section 6(e) will be paid by the Company to the Executive in the second calendar year; (b) the Executive continues to comply with the
provisions of the Non-Competition Agreement; and (c) prior to the expiration of the Consideration Period (i) Executive provides satisfactory evidence to the Company that he has returned all Company property, confidential information and
documentation to the Company, and (ii) provides the Company with a signed written resignation of Executive’s status as an officer of the Company or any of its affiliates, if applicable.

 Exhibit 10.3 

TRANSITION AGREEMENT 

AGREEMENT entered into as of this 13th day of March, 2014 by and between Hologic, Inc., a Delaware corporation with its principal place of
business at 35 Crosby Drive, Bedford, Massachusetts 01730 (the “Company”), and Glenn P. Muir, an individual having his principal residence in Lexington, Massachusetts (the “Executive”). 

WHEREAS, the Executive currently serves as Executive Vice President and Chief Financial Officer of the Company; 

WHEREAS, the Executive and the Company previously entered into a Retention and Severance Agreement, dated May 3, 2006 (the
“Severance Agreement”), and a Change of Control Agreement, dated November 11, 2009 (the “Change of Control Agreement”); 

WHEREAS, at the request of the Company, the Executive has agreed to retire and otherwise assist in the transition to a new Chief Financial
Officer, subject to the terms and conditions set forth herein. 
 NOW, THEREFORE, in consideration of the mutual covenants and agreements
hereinafter set forth, the parties hereto, each intending to be legally bound, do hereby agree as follows: 
 1. Resignation.
The Executive agrees and acknowledges that the Company is searching for his successor as Chief Financial Officer and that effective upon the Company’s appointment of such successor, the Executive will cease to serve as Chief Financial Officer
of the Company (the “Transition Date”). The Executive agrees to remain employed with the Company following the Transition Date to assist in the transition of his duties to his successor. Upon the Resignation Date (as defined below), the
Executive shall retire and resign employment with the Company. The parties hereto agree that such retirement and resignation, being made at the request of the Company, constitutes a termination without cause pursuant to Section 6.1(b) of the
Severance Agreement, and that the Executive shall be entitled to the rights and benefits thereunder as set forth in this Agreement. 
 2.
Transition Period. 
 (a) Title. Upon the Transition Date, the Executive shall be employed by the Company solely as
a full-time non-executive employee through November 30, 2014 (the “Resignation Date”; and the time between the Transition Date and the Resignation Date the “Transition Period”), subject to the terms and conditions of this
Agreement. The Executive further agrees that upon the Transition Date – or if no Transition Date occurs then upon the Resignation Date – the Executive will resign any and all positions held by him including, without limitation, as an
officer, director, manager, or member, as applicable, of the Company and all direct or indirect subsidiaries of the Company. Nothing herein shall preclude the Company from requiring the Executive to resign from any positions prior to the Transition
Date provided that any termination of employment shall be subject to Section 2(d), below. 
 (b) Duties. Prior to the
Transition Date, the Executive shall continue to serve as Chief Financial Officer with all the responsibilities and duties associated with such position. 

 
During the Transition Period and excluding any periods of vacation and sick leave to which the Executive is entitled, the Executive agrees to devote his full business time and best efforts to the
business and affairs of the Company in order to facilitate the transfer of duties to the Company’s new Chief Financial Officer. During the Transition Period, the Executive shall report directly to both the President and Chief Executive Officer,
and the Chief Financial Officer. The Executive further agrees to comply with the Company’s policies and procedures as they may be applicable to him (including without limitation, as an employee) as such policies and procedures may be modified
from time to time. 
 (c) Compensation. From the date hereof until the Resignation Date, unless the Executive’s
employment is terminated earlier, pursuant to Section 2(d) below, (i) the Executive shall be entitled to continue to receive base salary at a rate equal to his current annual base salary of $600,000 (“Base Salary”), payable in
accordance with the Company’s regular payroll practices; (ii) the Executive shall continue to participate in the Company’s Short-Term Incentive Plan for fiscal year 2014 (the “FY 2014 STIP”) in accordance with the terms
thereunder with payment, if any, to be made at such time as bonuses are paid under the FY 2014 STIP (it being understood that the Executive shall not participate in the fiscal year 2015 Short-Term Incentive Plan, unless he continues to serve as
Chief Financial Officer of the Company in FY 2015); (iii) the Executive’s outstanding stock option, restricted stock unit, performance stock unit and market stock unit awards will remain outstanding and, if applicable, will continue to
vest in accordance with and subject to the terms and conditions set forth in the applicable equity incentive plans and award agreements; and (iv) the Executive shall be entitled to participate in any and all retirement (both qualified and
non-qualified), vacation and/or sick pay, medical, dental, life insurance and other employee benefit plans in which he currently participates, all to the extent the Executive remains eligible under the terms of such plans and subject to the terms
and conditions of such plans as may be in effect from time to time, including (without limitation) the Company’s car allowance program. 

(d) Termination. The Executive’s employment during the Transition Period may be terminated (i) by the Company for
material breach by the Executive of the Company’s written policies and this Agreement, including the Employee Intellectual Property rights and Non-Competition Agreement dated May 3, 2006, but only after (x) the Executive has actually
received written notification detailing such material breach and (y) the Executive has been given a 10 business day period to cure such material breach, if curable (and if substantially cured within such 10 business day period, then
Executive’s employment shall not be terminated), or (ii) by reason of the Executive’s death. In the case of any termination of the Executive’s employment prior to the Resignation Date, the Executive’s entitlement to the
compensation and benefits provided in Section 2(c) shall immediately cease and the Executive’s entitlement to full, partial or pro-rated compensation and other benefits under the Company’s benefit plans and arrangements, if any, shall
be determined under the policies and benefit plans of the Company. 
 (e) Final Resignation. The Executive and the Company
agree that on the Resignation Date the Executive’s employment as a full-time non-executive employee shall terminate and the Transition Period shall end. On the Resignation Date, the Executive will receive his final paycheck with accrued and
unpaid pay through that date as well as accrued and unpaid vacation time and payment of all outstanding business expense reimbursements according to Company policy. 

  
 2 

 3. Separation Benefits. As a consequence of the termination of the Executive’s
employment with the Company on or after the Transition Date, or if no Transition Date occurs then upon the Resignation Date, in accordance with Section 6.1(b) of the Severance Agreement and in full discharge of the Company’s obligations
due to the Executive thereunder, the Company shall pay to the Executive or his heirs or estate, if applicable, subject to the Executive executing the Release Agreement attached hereto as Exhibit A within the applicable time period and not
revoking it, a severance amount (the “Severance Amount”) equal to the sum of (x) the Executive’s Base Salary and (y) an amount equal to the average of the annual bonuses paid or payable to the Executive under the
Company’s Short-Term Incentive Plan during the last three (3) fiscal years ended prior to the Resignation Date (including any amount electively deferred by the Executive pursuant to a qualified or non-qualified retirement plan), with 50%
of such Severance Amount payable in a lump sum on the first payroll date following the six-month anniversary of the Resignation Date and the remainder to be paid out pro-rata over the succeeding six month period in accordance with normal payroll
practices for the Company’s senior executive officers. On the first payroll date following the six-month anniversary of the Resignation Date, the Company will also pay the Executive a lump sum equal to COBRA continuation premiums for the
twelve-months following the Resignation Date. Each payment under this Section 3 described above is subject to applicable withholding and taxes. 

4. Non-Competition Agreement. As additional consideration for the substantial benefits being provided to the Executive
hereunder, the Executive agrees to continue to comply with the Non-Competition and Proprietary Information Agreement previously executed and agreed to by Executive. 

5. Other Severance Benefits. The separation pay and benefits provided for in Section 3 shall be in lieu of any other
severance or termination pay to which the Executive may be entitled under any Company severance or termination plan, program or practice (whether written or unwritten) or agreement. Except as otherwise provided herein, the Executive’s
entitlement to any other compensation or benefits shall be determined in accordance with the terms and conditions of the Company’s employee benefit plans (other than severance or termination plans, programs, practices or agreements) and other
applicable programs, policies and practices then in effect. For the avoidance of doubt, nothing herein shall alter, change or otherwise affect Executive’s rights under the Change of Control Agreement during the Transition Period, including
(without limitation) the right to accelerate vesting thereunder. 
 6. Successors: Binding Agreement. 

(a) This Agreement shall be binding upon and shall inure to the benefit of the Company, and its successors and assigns, and the Company
shall require any successors and assigns to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession or assignment had taken place. 

(b) Neither this Agreement nor any right or interest hereunder shall be assignable or transferable by the Executive, his beneficiaries
or legal representatives, except by will or by the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by the Executive’s personal representative. 

  
 3 

 7. Tax Treatment; Tax Withholding. The Company and the Executive hereby acknowledge
and agree that the compensation provided for in Section 2 and the severance pay provided for in Section 3 shall be treated and reported by the Company and the Executive as additional compensation for services rendered and as ordinary
income. The Executive also acknowledges and agrees that the Company may withhold from any compensation or other benefits to which the Executive is entitled hereunder such amounts as may be required to satisfy all federal, state and local withholding
and employment tax obligations. 
 8. General Provisions. 

(a) No Special Employment Rights. No provision of this Agreement shall grant or confer upon, or shall be construed to grant or
confer upon, the Executive any right with respect to the continuation of his employment by the Company or to otherwise affect in any respect the terms and conditions of such employment except to the extent expressly provided hereunder.

the Severance Agreement; provided, however, that the Change of Control Agreement shall terminate effective as of the Resignation Date, provided that the Company has not entered into a definitive agreement to effect a Change of Control (as such term

agreement, restricted stock unit agreement, performance stock unit agreement, market stock unit agreement or other equity instrument by and between the Company and the Executive) shall remain in full force and effect in accordance with the terms and
conditions herein and therein. This Agreement may not be changed orally, but only by an agreement in writing signed by the party against whom enforcement of any such change is sought.

agree that said court in making such determination shall have the power to reduce the duration and scope of such provision to the extent necessary to make it enforceable, and that the Agreement in its reduced form shall be valid and enforceable to
the full extent permitted by law. 
 (h) Governing Law/Jurisdiction. This Agreement shall be binding upon the Executive and
shall inure to the benefit of the Company and its successors and interest and assigns, and shall be construed in accordance with and governed by the laws of the Commonwealth of Massachusetts without regard to conflicts of laws. The parties hereto
intend and hereby confer jurisdiction to enforce the covenants contained herein upon the state and federal courts sitting in the Commonwealth of Massachusetts. In the event that such courts shall hold any such covenant wholly unenforceable by reason
of the breadth of scope or otherwise, it is the intention of the parties hereto that such determination not bar or in any way affect the Company’s right to the relief provided above in the courts of any other states within the geographical
scope of such other covenants having appropriate personal and subject matter jurisdiction over the parties, as to breaches of such covenants in such other respective jurisdictions, the above covenants as they relate to each state being, for this
purpose, severable into diverse and independent covenants. 
 (i) Counterparts. This Agreement may be executed in multiple
counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 
 IN
WITNESS WHEREOF, the parties hereto have duly executed this Agreement as a binding contract as of the date first above written.

 (e) Entire Agreement; Amendment. The recitals hereto are hereby incorporated herein
by this reference. This Release Agreement, together with the Transition Agreement and the exhibits thereto and hereto, constitute the entire agreement between the parties hereto and thereto with regard to the subject matter hereof and thereof,
superseding all prior understandings and agreements, whether written or oral, including, without limitation, the Severance Agreement; provided, however, that the Change of Control Agreement shall terminate effective as of the Effective Date,
provided that the Company has not entered into a definitive agreement to effect a Change of Control (as such term is defined in the Change of Control Agreement) prior to the Effective Date and further provided that any indemnification agreement and
any outstanding vested equity award agreements (including, without limitation, any outstanding vested option agreement, restricted stock unit agreement, performance stock unit agreement, market stock unit agreement or other equity instrument by and
between the Company and the Executive) shall remain in full force and effect in accordance with the terms and conditions herein and therein. This Release Agreement may not be changed orally, but only by an agreement in writing signed by the party
against whom enforcement of any such change is sought. 
 (f) Interpretation. The parties hereto acknowledge and agree that:
(i) each party and its counsel reviewed and negotiated the terms and provisions of this Release Agreement and have contributed to its revision; (ii) the rule of construction to the effect that any ambiguities are resolved against the
drafting party shall not be employed in the interpretation of this Release Agreement; and (iii) the terms and provisions of this Release Agreement shall be construed fairly as to all parties hereto and not in favor of or against any party,
regardless of which party was generally responsible for the preparation of this Release Agreement. 
 (g) Effect of Headings.
The titles of section headings herein contained have been provided solely for convenience of reference and in no way define, limit or describe the scope or substance of any provision of this Release Agreement. 

(h) Severability. The provisions of this Release Agreement are severable, and the invalidity of any provision shall not affect
the validity of any other provision. In the event that any court of competent jurisdiction shall determine that any provision of this Release Agreement or the application thereof is unenforceable because of the duration or scope thereof, the parties
hereto agree that said court in making such determination shall have the power to reduce the duration and scope of such provision to the extent necessary to make it enforceable, and that the Release Agreement in its reduced form shall be valid and
enforceable to the full extent permitted by law. 
 (i) Governing Law/Jurisdiction. This Release Agreement shall be binding
upon the Executive and shall inure to the benefit of the Company and its successors and interest and assigns, and shall be construed in accordance with and governed by the laws of the Commonwealth of Massachusetts without regard to conflicts of
laws. The parties hereto intend and hereby confer jurisdiction to enforce the covenants contained herein upon the state and federal courts sitting in the Commonwealth of Massachusetts. In the event that such courts shall hold any such covenant
wholly unenforceable by reason of the breadth of scope or otherwise, it is the intention of the parties hereto that such determination not bar or in any way affect the Company’s right to relief in the courts of any other states within the
geographical scope of such other covenants having appropriate personal and subject matter jurisdiction over the parties, as to breaches of such covenants in such other respective jurisdictions, the above covenants as they relate to each state being,
for this purpose, severable into diverse and independent covenants.

 (j) Counterparts. This Release Agreement may be executed in multiple counterparts,
each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.
