ANNUAL NOTICES FOR THE COORSTEK LLC Plan Number 002 CoorsTek LLC ( CoorsTek ) sponsors the CoorsTek LLC Savings and Investment Plan ( Plan ) to help you prepare for retirement. These Notices are provided pursuant to the Pension Protection Act of 2006. They explain several important features of the Plan, including: (1) how automatic enrollment works under the Plan for affected employees, (2) the default investment alternative that applies under the Plan if you do not direct the investment of your account, and (3) your rights and obligations under a design-based safe harbor 401(k) plan. These Notices also explain how to change your contribution election or your investment election under the Plan. If you have questions about the information in these Notices, please contact Fidelity Investments ( Fidelity ) by calling the Fidelity automated telephone service at 1 800 354 3964. If you prefer, you can speak to a Fidelity Participant Services Representative at 1 800 354 3964 between 8:30 a.m. and 8:00 p.m. in your local time zone, Monday through Friday. You may also find information and make changes online by logging on to Fidelity NetBenefits at www.401k.com. Please have your Social Security number and personal identification number (PIN) available when you call or log on. Automatic Enrollment Notice If you are an employee hired by CoorsTek or one of its subsidiaries on or after January 1, 2008, unless you elect otherwise, CoorsTek will automatically enroll you in the Plan and withhold 3% of your Compensation (as defined under the Plan) and contribute it to the Plan on your behalf, effective on the first day of the first month following the 30-day anniversary of your date of hire. This 3% automatic contribution level will increase by 1% per year until it reaches 6% and will continue to apply until you change it. You have the right to change your contribution percentage or to stop contributing altogether, but you must affirmatively elect to do so. Unless you have elected otherwise, your automatic enrollment contributions and the employer s matching contributions are invested in the default investment option described in the Default Investment Option Notice. You have the right to direct the investment of your contributions and your account balance to the Plan s other available investment options. Also, you may designate a beneficiary to indicate to whom any benefits should be paid in the event of your death by following the procedures established by the Plan Administrator. Keep in mind that CoorsTek matches one dollar for each dollar you contribute, up to the first 6% of your eligible compensation, for a maximum match of 6% of your eligible compensation. So, to get the most from the employer matching contributions, you must contribute at least 6% of your eligible compensation. You may change the rate of your contributions or stop your contributions as of the first day of any pay period. If you make the change far enough in advance of payroll processing, the change will be effective for the next paycheck you will receive. Otherwise, the change will be effective for the following paycheck. Default Investment Option Notice The Plan lets you invest in a number of different investment options. You have the right to designate how all contributions and earnings to your account will be invested among the available Plan investment options. If you do not designate how contributions and earnings should be invested, they are invested in the Plan s default investment option. This could occur if: (a) you are automatically enrolled in the Plan, (b) you elect to make contributions to the Plan but do not designate an investment option, (c) you make rollover contributions to the Plan but do not designate an investment option, (d) CoorsTek makes employer contributions to the Plan and you do not designate an investment option, or (e) there is a service provider change that requires a fund transfer and you do not designate an investment option. The Plan s default investment is the Fidelity Freedom K Fund for your age when you are first eligible to contribute, based on an assumed retirement age of 65. A detailed description of the Fidelity Freedom K Fund is included with this Notice and is incorporated into this Notice. The description explains the fund s investment objectives, risk and return characteristics, and fees and expenses. You can change this default investment election at any time without financial penalty. Any change you make will generally be effective on the next business day, unless unusual market conditions dictate otherwise or unless the Plan is in a blackout period due to implementation of changes, upgrades, maintenance or similar activities. Contact Fidelity, as outlined below, for information about the available investment options, including the Fidelity Freedom K Funds. 2 coorstek.com +1 303 271 7000 benefits@coorstek.com

You may use the automated telephone service 24 hours a day or call Monday through Friday from 8:30 a.m. to 8 p.m. in your local time zone to speak with a Fidelity Participant Services Representative. You may also make changes online by logging on to Fidelity NetBenefits at www.401k. com. Please have your Social Security number and personal identification number (PIN) available when you call or log on. Design Based Safe Harbor 401(k) Plan Notice This notice is to advise you that the Plan meets a design-based safe harbor method for satisfying the 401(k) nondiscrimination tests required by the Internal Revenue Code (the average deferral percentage ( ADP ) test and the average contribution percentage ( ACP ) test). This notice describes the safe harbor contributions and related Plan provisions. Contributions Salary Reduction Contributions You may elect to reduce your Compensation and have the Employer contribute the amount of the reduction to the Plan on your behalf. These contributions are called Salary Reduction Contributions. Because you do not receive these amounts, these contributions are not subject to federal income tax and, in most states, state income tax, in the year in which they are made. Thus, you delay paying income taxes on this money until it is actually paid out of the Plan to you. Your Salary Reduction Contributions are subject to Social Security ( FICA ) taxes. For purposes of calculating contributions to the Plan, your Compensation includes the total pay for services rendered that you received from the Employer during the Plan Year (each January 1 through the following December 31) while you were a participant. In addition, Compensation includes salary reduction-type contributions to this Plan, and to any cafeteria plan, flexible spending account plan, qualified transportation fringe benefit plan, or dependent care assistance plan. Compensation excludes fringe benefits (cash and noncash), reimbursements and other expense allowances, moving expenses, deferred compensation and welfare benefits, including but not limited to adoption assistance, baby seat reimbursement, car allowances, fitness reimbursement and tuition reimbursement. The Employer automatically applies your elected contribution percentage to your Compensation. Automatic Election of Salary Reduction Contributions Effective with respect to employees hired on or after January 1, 2008, unless you elect otherwise, the Employer will automatically withhold 3% of your Compensation and contribute it to the Plan on your behalf as Salary Reduction Contributions, effective when you are first eligible to contribute. Each year after you are automatically enrolled, your salary reduction contributions will be increased by 1% until they reach 6%. For example if you are automatically enrolled during 2008 your initial rate of contributions was 3%. This contribution percentage was increased to 4% for 2009, 5% for 2010, and 6% for years after 2010, unless it is changed by you in accordance with Plan procedures. Your contributions will be invested in the Fidelity Freedom K Fund for the year closest to your normal retirement age (65), based on your age when you are first eligible to contribute. You can change this default investment election at any time by following the procedures established by the Plan Administrator. If you wish to avoid automatic withholding of Salary Reduction Contributions, change your contribution percentage, or invest your contributions in another available fund, you must elect otherwise in accordance with procedures established by the Plan Administrator. Catch-up Contributions If you attain age 50 or over before the end of a Plan Year you are permitted to contribute an additional Catch-up Contribution. Your Catchup Contributions for a Plan Year cannot exceed your Compensation minus your Salary Reduction Contributions. Limitations on Salary Reduction and Catch-up Contributions. In general, you may elect to contribute any percentage of your Compensation (including an election to not contribute at all). However, if you elect to contribute to the Plan, the amount of your contribution can never be less than 1% of your Compensation and never more than 80% of your Compensation after subtracting all voluntary and mandatory deductions and withholdings. The following other limitations may also apply. 2017 Disclosures Packet 3

ANNUAL NOTICES FOR THE COORSTEK LLC (a) Under federal law, the maximum amount of salary reduction-type contributions you can make to all 401(k) and 403(b) plans in which you participate in a calendar year is $18,000 for 2016. This limit is indexed for inflation. This dollar limit applies to your Salary Reduction Contributions under this Plan as well as any other 401(k) and 403(b) savings plans in which you may participate in the same year. Catch-up Contributions are not taken into account for this Salary Reduction Contribution limit. Catch-up Contributions may be made by eligible participants in amounts over and above the limit mentioned above. If you are an eligible participant, you may make Catch-up Contributions in the amount of $6,000 for 2016. This limit is also indexed for inflation. (b) Federal law also limits the total amount that can be added to your accounts under the Plan and any other qualified plans maintained by the Employer. In general, the limit is the lesser of 100% of your Compensation from the Employer or $53,000. Catch-up Contributions are not counted for the $53,000 limitation but are counted for the 100% of Compensation limitation. The $53,000 limitation is indexed for inflation and may be increased. Making Changes in Your Contributions You may begin, suspend, resume or change the rate of your contributions during any pay period, effective for the next paycheck you will receive, if you make the change far enough in advance of the payroll processing, otherwise effective for the following paycheck. The Plan Administrator may impose limits on the number of permitted changes. To make any of these types of changes, you must follow the procedure established by the Plan Administrator. Employer Matching Contribution Formula To encourage you to make contributions to the Plan, your Employer makes Employer Matching Contributions equal to 100% of your Salary Reduction Contributions and Catch-up Contributions up to the first 6% of your Compensation. This Employer Matching Contributions formula is intended to meet the requirements of a safe harbor under the Internal Revenue Code which eliminates the need for the Employer to determine whether the Salary Reduction Contributions and Employer Matching Contributions made under the Plan satisfy certain nondiscrimination tests. Your Employer may also, in its discretion, make an additional non-safe harbor match. If your Employer makes an additional non-safe harbor match, this match will be allocated proportionately to all of your Employer s participants who made Salary Reduction Contributions. For example, assume you earn $30,000 of Compensation annually and that the only match is the safe-harbor match. If you elect to defer 6% of your Compensation, your Employer would withhold $1,800 from your pay checks during the year. Your Employer would match dollar for dollar of the first 6% of Compensation for a total Employer Matching Contribution of $1,800 (or a maximum of 6% of your Compensation). Profit Sharing Contribution. In addition to the Employer s Matching Contributions, each year the Employer, in its sole discretion, will determine whether it will make a Profit Sharing Contribution and the amount, if any, of its contribution. The Employer is not required to make a Profit Sharing Contribution for any Plan Year. Vesting You are always 100% vested in your Salary Reduction Contributions account and Employer Matching Contributions account, as well as your other Plan accounts. Loans and In-Service Distributions Distributions Prior to Termination of Employment Generally, the Plan is designed to provide for your financial security when you are no longer working. However, in some circumstances, it may be in your best interest to be able to have access to your benefits prior to termination of your employment. Consequently, the Plan provides that you may borrow money from your vested accounts and, under certain circumstances, withdraw funds from your accounts. Loans The Plan provides that participants may borrow funds from their vested account balances. The loan program is administered by the Plan Administrator. In order to obtain a loan, you must submit an application to the Plan Administrator. The maximum amount of any single loan is the lesser of: (1) $50,000 minus all outstanding loans from the plan minus the excess of the highest total amount of outstanding loan balances in the previous 12-month period over the outstanding balance on the date the loan is made, or (2) one-half of the eligible individual s vested account balance. 4 coorstek.com +1 303 271 7000 benefits@coorstek.com

Account Balances of More than $5,000 If your Plan account balance exceeds $5,000 when you terminate your employment with the Employer, or if you terminate employment because of a disability (as defined in the Plan), you may elect to receive the entire amount in your Plan accounts in a lump sum or in a series of payments (made monthly, quarterly, semi annually, or annually).

There may be a minimal charge for copying costs. 2017 Disclosures Packet 5
