 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.

 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.

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.

counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.
