 Exhibit 10.5 
 THERMO FISHER SCIENTIFIC INC. 
 NONSTATUTORY STOCK OPTION AGREEMENT

 Granted Under 
 Thermo Fisher Scientific Inc. 2008 Stock Incentive Plan 
 1. Grant of Option.

 This agreement evidences the grant by Thermo Fisher Scientific Inc., a Delaware corporation (the “Company”), on
February 26, 2013 (the “Grant Date”) to Marc N. Casper (the “Participant”), an employee and officer of the Company, of an Option to purchase, in whole or in part, on the terms provided herein and in the Company’s 2008
Stock Incentive Plan (the “Plan”), a total of 161,200 shares (the “Shares”) of common stock, $1.00 par value per share, of the Company (“Common Stock”) at $73.24 per Share. Unless earlier terminated, this Option shall
expire at 5:00 p.m., Eastern time, on February 26, 2020 (the “Final Exercise Date”). 
 It is intended that this
Option evidenced by this agreement shall not be an incentive stock option as defined in Section 422 of the Code. Except as otherwise indicated by the context, the term “Participant”, as used in this Option, shall be deemed to include
any person who acquires the right to exercise this Option validly under its terms. Capitalized terms used in this Agreement and not otherwise defined shall have the same meaning as in the Plan. 

2. Vesting Schedule. Except as otherwise provided in paragraphs (c) through (f) of Section 3 below and the Plan, this Option will
become exercisable (“vest”) as to 25% of the original number of Shares on the first anniversary of the Grant Date and as to an additional 25% of the original number of Shares on each anniversary of the Grant Date following the first
anniversary of the Grant Date until the fourth anniversary of the Grant Date provided that on each such vesting date, the Participant is, and has been at all times since the Grant Date, an employee, officer or director of, or consultant or advisor
to, the Company (an “Eligible Participant”). The right of exercise shall be cumulative so that to the extent the Option is not exercised in any period to the maximum extent permissible it shall continue to be exercisable, in whole or in
part, with respect to all Shares for which it is vested until the earlier of the Final Exercise Date or the termination of this Option under Section 3 hereof. 
 3. Exercise of Option. 
 (a) Form of Exercise. Each election to
exercise this Option shall be in accordance with the instructions provided from time to time by the Company. The Participant may purchase less than the number of shares covered hereby, provided that no partial exercise of this Option may be for any
fractional share. 
 (b) Termination of Relationship with the Company. If the Participant ceases to be an Eligible
Participant for any reason, then, except as provided in paragraphs (c) through (f) below, the right to exercise this Option shall terminate three months after such cessation (but in no event after the Final Exercise Date), provided
that this Option shall be exercisable only to the extent that the Participant was entitled to exercise this Option on the date of such cessation.

 (c) Death or Disability. If the Participant dies or becomes disabled (as defined
below) prior to the Final Exercise Date while he is an Eligible Participant, this Option shall vest and become 100% exercisable upon the date of such death or disability and the right to exercise this Option shall terminate one year following such
date (but in no event after the Final Exercise Date). For the purposes of this Agreement, a Participant shall be deemed to be “disabled” at such time as the Participant is receiving disability benefits under the Company’s Long Term
Disability Coverage, as then in effect. 
 (d) Discharge Without Cause or for Good Reason. If the Participant’s
employment or service is terminated by the Company or any Subsidiary without “Cause” (as defined in Section 1.2 of the 2009 Restatement of Executive Severance Agreement between the Company and the Participant dated November 21,
2009, as may be amended from time to time (the “Severance Agreement”)) or by the Participant for Good Reason (as defined in Section 1.4 of the Severance Agreement), and such termination does not entitle the Participant to severance
benefits under the Executive Change in Control Retention Agreement between the Company and the Participant dated November 21, 2009, as may be amended from time to time (the “CIC Agreement”) prior to the Final Exercise Date, the
unvested portion of this Option shall vest as to the 25% tranche of this Option next scheduled to vest under this Agreement (the “Accelerated Option Shares”), and the Accelerated Option Shares shall become exercisable upon the date of such
termination of employment or service, and the right to exercise this Option (including the Accelerated Option Shares) shall terminate two years following such date (but in no event after the Final Exercise Date). 

(e) Discharge for Cause. If the Participant, prior to the Final Exercise Date, is discharged by the Company or a Subsidiary for
“Cause” (as defined in Section 1.2 of the Severance Agreement), the right to exercise this Option shall terminate immediately upon the effective date of such discharge. The Participant shall be considered to have been discharged for
Cause if the Company determines, within 30 days after the Participant’s resignation, that discharge for Cause was warranted. 
 (f) Change in Control Event. If the Participant’s employment or service is terminated by the Company or any Subsidiary without “Cause” (as defined in Section 1.3 of the CIC
Agreement) or by the Participant for Good Reason (as defined in Section 1.4 of the CIC Agreement) and such termination entitles the Participant to severance benefits under the CIC Agreement, this Option shall vest and become 100% exercisable
upon the date of such termination of employment or service and the right to exercise this Option shall terminate two years following such date (but in no event after the Final Exercise Date). 
 4. Withholding. No Shares will be issued pursuant to the exercise of this Option unless and until the Participant pays to the Company, or makes provision satisfactory to the Company for payment of,
any federal, state or local withholding taxes required by law to be withheld in respect of this Option in accordance with the instructions provided from time to time by the Company; provided, however, except as otherwise permitted by
the Board, the total tax withholding where stock is being used to satisfy such tax obligations cannot exceed the 

  
 2 








 
Company’s minimum statutory withholding obligations (based on minimum statutory withholding rates for federal and state tax purposes, including payroll taxes, that are applicable to such
supplemental taxable income). 
 5. Nontransferability of Option. This Option may not be sold, assigned, transferred, pledged or
otherwise encumbered by the Participant, either voluntarily or by operation of law, except by will or the laws of descent and distribution, and, during the lifetime of the Participant, this Option shall be exercisable only by the Participant.
Notwithstanding the foregoing, the Company consents to the gratuitous transfer of this Option by the Participant to or for the benefit of any immediate family member, family trust or family partnership established solely for the benefit of the
Participant and/or an immediate family member thereof; provided that with respect to such proposed transferee the Company would be eligible to use a Form S-8 for the registration of the sale of the Common Stock subject to such Option under
the Securities Act of 1933, as amended; and provided further that the Company shall not be required to recognize any such transfer until such time as the Participant and such permitted transferee shall, as a condition to such transfer,
deliver to the Company a written instrument in form and substance satisfactory to the Company confirming that such transferee shall be bound by all of the terms and conditions of this Agreement. 

6. Provisions of the Plan. This Option is subject to the provisions of the Plan, a copy of which is furnished to the Participant with this Option.

 7. No Right To Employment or Other Status. The grant of this Option shall not be construed as giving the Participant the right to
continued employment or any other relationship with the Company or Subsidiary. The Company and Subsidiaries expressly reserve the right at any time to dismiss or otherwise terminate its relationship with the Participant free from any liability or
claim under the Plan or this Agreement, except as expressly provided herein. 
 8. Restrictive Covenants. If the Participant engages in
any conduct in breach of any noncompetition, nonsolicitation or confidentiality obligations to the Company or any Subsidiary under any agreement, policy or plan of the Company or any Subsidiary, then such conduct shall also be deemed to be a breach
of the terms of the Plan and this Agreement. Upon such breach, this Option shall be cancelled and, to the extent some or all of this Option was exercised within a period of 12 months prior to such breach, the Participant shall be required to forfeit
to the Company, upon demand, any cash or Shares acquired by the Participant upon such exercise or sale. 
 9. Governing Law. This Option
shall be governed by and interpreted in accordance with the laws of the State of Delaware, without regard to any applicable conflicts of law.

 IN WITNESS WHEREOF, the Company has caused this Option to be executed under its corporate
seal by its duly authorized officer. This Option shall take effect as a sealed instrument.
