COMPENSATION PLAN INFORMATION

We have two equity compensation plans that have been approved by our stockholders:

the Littelfuse, Inc.

Long-Term Incentive Plan that was approved by our stockholders at the April 2017 annual stockholder meeting and the Deferred Compensation Plan for Non-Employee Directors that was approved by our stockholders at the May 2005 annual stockholder meeting.

Pursuant to our acquisition of IXYS Corporation on January 17, 2018, we assumed four equity compensation plans that have not been approved by our stockholders and pursuant to which we may continue to grant equity awards:

IXYS Corporation 2009 Equity Incentive Plan, IXYS Corporation 2011 Equity Incentive Plan, IXYS Corporation 2013 Equity Incentive Plan, IXYS Corporation 2016 Equity Incentive Plan (together, the "IXYS Plans").

We also assumed two expired equity compensation plans that have not been approved by our stockholders and pursuant to which we have outstanding equity awards:

the Zilog, Inc.

2002 Omnibus Stock Incentive Plan and Zilog, Inc.

2004 Omnibus Stock Incentive Plan (together the "Zilog Plans").

The IXYS Corporation 2009 Equity Incentive Plan expired in June 2019 and equity awards remain outstanding under it.

Information about our equity compensation plans that were either approved or not approved by our stockholders as of December 26, 2020, is as follows:

Plan Category Number of securities to

be issued upon exercise of outstanding options, warrants and rights Weighted-average exercise price of outstanding options, warrants, and rights

(1) Number of securities remaining available for future issuance under equity compensation plans (excluding securities reflected in the first column)

Equity compensation plans approved by security holders 719,991 (2) $157.84 699,516 (4)

Equity compensation plans not approved by security holders 129,913 (3) $104.49 206,617 (5)

Total 849,904 $148.01 906,133

(1) The weighted average exercise price does not take into account the shares issuable upon the vesting of outstanding restricted stock units, which have no exercise price.

(2) Includes 175,819 shares reserved for issuance upon vesting of outstanding restricted stock units and 544,172 outstanding stock options granted under the Littelfuse, Inc.

Long-Term Incentive Plan.

(3) Includes 7,136 shares reserved for issuance upon vesting of outstanding restricted stock units under the IXYS Plans and 122,777 outstanding stock options granted under the IXYS Plans and Zilog Plan.

Below is a brief description of the material features of the compensation plans acquired pursuant to the acquisition of IXYS Corporation.

(4) Includes 654,869 shares that remain available for future issuance under the Littelfuse, Inc.

Long-Term Incentive Plan and 44,647 shares that remain available for future issuance under the Deferred Compensation Plan for Non-Employee Directors.

(5) Includes 11,385 shares that remain available for future issuance under the IXYS Corporation 2011 Equity Incentive Plan, 26,689 shares that remain available for future issuance under the IXYS Corporation 2013 Equity Incentive Plan, and 168,543 shares that remain available for future issuance under the IXYS Corporation 2016 Equity Incentive Plan.

In connection with the acquisition of IXYS Corporation, we assumed the IXYS Corporation 2009 Equity Incentive Plan, IXYS Corporation 2011 Equity Incentive Plan, IXYS Corporation 2013 Equity Incentive Plan, IXYS Corporation 2016 Equity Incentive Plan and outstanding unvested stock options originally granted by IXYS Corporation under the IXYS Plans that were held by continuing employees.

At the time of the acquisition of IXYS Corporation, these awards were converted to Littelfuse stock options, with adjustments made to the exercise price of the stock options and the number of shares subject to stock options as agreed upon in the Acquisition Agreement.

These unvested options vest in accordance with their original terms, generally vesting in equal annual installments over a four-year period from the original grant date.

The options, once granted, generally expire ten years from the date of grant.

Under the IXYS Plans, we may grant to former employees of IXYS Corporation or its subsidiaries restricted stock awards, RSUs, stock options and stock appreciation rights with an exercise price that is no less than the fair market value on the date of grant.

Equity awards granted under the IXYS Plans following the acquisition have been on similar terms and consistent with grants made pursuant to the Littelfuse, Inc Long-Term Incentive Plan.

The IXYS Corporation 2009 Equity Incentive Plan expired in June 2019 and no additional grants were made after the expiration date.

As of December 26, 2020, 206,617 shares remained available for issuance under the IXYS Plans.

In connection with the acquisition of IXYS Corporation, we assumed the Zilog, Inc.

2004 Omnibus Stock Incentive Plan and outstanding stock options originally granted by IXYS Corporation under the Zilog Plan that were held by continuing employees of Zilog.

These options vested in accordance with their original terms, generally in equal annual installments over a four-year period from the original grant date.

The options generally expire ten years from the date of grant.

The Zilog 2004 Omnibus Stock Incentive Plan expired in February 2014 and no additional grants have been made thereunder.

Therefore, as of December 26, 2020, no shares remain available for issuance of new awards under the Zilog Plan and 20,499 stock options remain outstanding.
