Open Enrollment is the one time every year that you can adjust your benefits so they continue to be the right fit for you and your family. Unless you experience a qualifying life event, this is the only time you can make plan changes, add or drop coverage for dependents, or enroll in a new plan.

Enroll October 28–November 11, 2026

Now is the time to sign up for the benefits you and your family need for 2027. So no matter what comes your way, you’ve got it covered.

Take some time to explore the benefits available to you. Then, choose the coverage you want for you and your family. Your benefit elections are effective January 1, 2027.

If you don’t enroll, you’ll have the same medical, dental, and vision plans you have in 2026, and you will not have a Health Care Flexible Spending Account (FSA) or Dependent Day Care FSA.

Who’s eligible for benefits

If you’re a full-time or part-time regular-status Lam or Silfex employee who works 20 or more hours per week, you’re eligible for Lam benefits. Your spouse or domestic partner and children may also be eligible. No other family members, including parents, are eligible, even if they live with you.

Definition of eligible spouse

A person is your spouse if you are legally married to each other, and the marriage has not been legally terminated, and you and your spouse are not legally separated.

Definition of eligible domestic partner

You must attest that all the following criteria have been met for your same-sex or opposite-sex domestic partner to qualify for coverage:

  • You are both at least 18 years old and live together in the same residence and intend to do so indefinitely. You have resided in the same household for at least 12 months.
  • You are engaged in an intimate, committed relationship of mutual caring and support and are jointly responsible for your common welfare and living expenses.
  • You are each other’s sole domestic partner, and you intend to remain so indefinitely.
  • Neither of you is married nor have you had another domestic partner within the prior 12 months.
  • You are not related by blood to such a degree that you would be prevented from marrying in the state in which you live.

Definition of eligible child

A child who is under age 26 who is:

  • Your, your spouse’s, or your domestic partner’s natural child, stepchild, or legally adopted child or a child who is in the process of being adopted
  • A child for whom you, your spouse, or your domestic partner has been appointed legal guardian (you must provide documentation)
  • A child for whom you, your spouse, or your domestic partner is required to provide coverage under a qualified medical child support order
  • An unmarried child of any age if he or she is dependent on you, your spouse, or your domestic partner for support due to a physical or mental disability

What’s changing

You’ll have the same choices for medical, dental, and vision plans for 2027. Following are some plan changes for 2027.

Computer vision care added for dependents

Family members enrolled in your vision plan will have access to the same coverage you get for computer vision exams, eyeglass frames, and lenses.

For details, visit the Vision page.

Higher HSA savings limit

If you enroll in a Consumer Directed Health Plan (CDHP), Lam will make a generous contribution of up to $1,300 to your Health Savings Account (HSA) if you have individual coverage and up to $2,600 if you cover yourself and one or more dependents. Plus, you can contribute even more to your HSA, with higher IRS limits in 2027:

  • Up to $3,200 if you have individual coverage (for a total of $4,500 with Lam’s contribution)
  • Up to $6,400 if you cover yourself and one or more dependents (for a total of $9,000 with Lam’s contribution)
  • Up to an additional $1,000 if you’re age 55 or older in 2027

Your 2026 contribution elections will roll over to 2027, so be sure to increase your contributions during Open Enrollment if you want to hit the new maximum amount.

Medical plan contributions will increase

Medical costs continue to rise nationally, but thankfully, Lam’s health care cost increase trend is below the national average. 

You’ll contribute more from each paycheck for medical plan coverage in 2027, but Lam continues to cover about 85% of the cost of medical coverage for you and your family. 

The cost for dental and vision coverage will not change.

Anthem and Kaiser CDHPs: Higher deductible for individual in a family

To meet IRS requirements, the individual-in-a-family deductible for the Anthem and Kaiser Consumer Directed Health Plans (CDHPs) will increase to $3,500 (from $3,400).

The plan will begin to pay benefits for a family member once that person has met the individual-in-a-family deductible.

Weight-loss drug coverage in Anthem CDHP

Lam’s medical plans continue to provide coverage for GLP-1 drugs. Under the Anthem CDHP, these drugs are covered under a specific preventive drug list managed by CVS Caremark. To provide more consistency in plan coverage across our medical plans, we are making a change in how GLP-1 weight-loss drugs are covered under the Anthem CDHP in 2027.

If you are enrolled in the Anthem CDHP and prescribed a GLP-1 solely for weight loss, the amount you pay for the drug will change in 2027: You will pay 20% coinsurance after you meet your deductible, up to your annual out-of-pocket maximum. Coverage for GLP-1 drugs prescribed for diabetes will not be affected by this change. If you have questions about how a specific drug will be covered, contact CVS Caremark at 800-378-0780.

There is no change to GLP-1 coverage for Anthem PPO and Kaiser plan participants: You will continue to pay a copayment or coinsurance as you did in 2026.

Short-term disability (STD) changes

You don’t need to do anything during Open Enrollment, but you should know about these changes for the STD plan (and VDI in California), starting January 1, 2027:

  • To be approved for STD, you must be out of work for seven consecutive calendar days. If approved, your STD benefits will be paid back to your first day missed, so you don’t need to use sick time or PTO for that first week. 
  • Your STD benefit covers 75% of your base salary, and there’s no longer a limit to the weekly benefit amount you can receive.
  • You’ll continue to pay 0.5% of your pay for STD coverage, but the wage cap for contributions will increase from $159,000 in 2026 to $190,200, which is the estimated Social Security wage cap for 2027. The maximum contribution will increase from $795 in 2026 to $951 in 2027.
  • To enable the plan to make tax-free payments when you receive benefits for your own medical condition, you’ll pay a small amount of imputed income tax for the amount Lam contributes to your STD coverage.

In some states, you can opt out of the STD plan during Open Enrollment. But think before you do that: If you decline coverage, you will not receive any STD benefits if you need to miss work because you have a baby, get sick, or need to care for a family member.

More ways you’ve got life covered

No matter what comes your way, you can trust that your Lam benefits provide the support you need. Open Enrollment is the time to ensure you have the coverage you and your family will need in the coming year. Think about how your needs may have changed, and consider how these programs may help you.

Be ready for the unexpected with voluntary supplemental medical benefits

Your medical plan from Lam (or somewhere else) pays for care to keep you healthy and get you back on your feet when you’re sick or injured. But medical insurance won’t help you pay your rent or other everyday expenses.

That’s where these voluntary supplemental medical benefits from MetLife can come in handy. The plans pay money directly to you, which you can use for your out-of-pocket medical expenses, like copays and deductibles—or for household expenses and bills.

You can enroll in the supplemental medical benefit plans only during Open Enrollment. You can purchase coverage for yourself, your spouse or domestic partner, and your children, without answering health questions. You pay for these plans with after-tax payroll deductions, so any benefits you receive are not taxed when a claim is paid.

  • Accident insurance pays you a lump-sum payment if you’re injured in an accident.
  • Hospital indemnity insurance pays you a lump-sum payment when you’re admitted to a hospital—plus a per-day payment for each day of your stay. The plan covers hospitalization due to injury, illness, and childbirth.
  • Critical illness insurance provides you with a lump-sum payment of $15,000, $30,000, or $50,000 (depending on the coverage level you select) when you’re diagnosed with a covered health condition.
     

Earn a $50 screening benefit

If you enroll in the hospital indemnity plan and/or critical illness plan, you and your covered dependents can each earn a $50 annual benefit when you complete one of more than 50 eligible health screenings.

Claim your 2026 FSA expenses

Reimbursement requests for eligible 2026 Health Care FSA or Dependent Day Care FSA expenses must be approved by March 31, 2027, so be sure to submit them well before that date.

You can carry over only up to $680 from your 2026 Health Care FSA to your 2027 FSA. You will forfeit any Dependent Day Care FSA balance that is unused at the end of 2026.

Elect your 2027 FSA contributions

For 2027, you can contribute up to $3,400 to a Health Care FSA. You will be able to carry over up to $680 from your 2026 Health Care FSA to your 2027 FSA. The IRS may increase the rollover limit for 2028.

You can also contribute up to the IRS limit, $7,500, to a Dependent Day Care FSA if you’re single or if you’re married and filing a joint tax return, or $3,750 if you’re married and filing separate tax returns.

You will forfeit any unused Dependent Day Care FSA balance at the end of 2026 and at the end of 2027.

Note: If your projected 2027 earnings are higher than $160,000, you will be permitted to contribute up to $4,300 to a Dependent Day Care FSA, including the 15% matching contribution from Lam. This limit—which is more than last year’s $3,000 limit—is intended to help the company comply with IRS regulations regarding plan use by highly compensated employees. If the midyear nondiscrimination test shows that Lam does not meet the IRS requirements, your contribution limit may be further reduced. Lam will notify you if this happens.

Gain peace of mind with extra protection

You can elect the ARAG legal plan for yourself, your parents, and your grandparents for support with a wide variety of legal concerns. And you can enroll in LifeLock identity theft protection to get proactive identity theft monitoring and expert identity restoration support, if needed. You can only add or drop this coverage during Open Enrollment.

Are the people you love protected?

Make sure you’ve named the beneficiaries who will receive the money from your life insurance, 401(k), HSA, and ESPP after you’re gone.

 Learn how

If you take no action during Open Enrollment

  • Your 2026 elections for medical, dental, and vision benefits will roll over to 2027 for you and your covered dependents.
  • If you waived health care coverage in 2026, you will not have Lam health care coverage in 2027.
  • You will not be able to contribute to a Health Care FSA or Dependent Day Care FSA in 2027.
  • If you currently contribute to an HSA, your 2026 HSA employee contribution amount election will roll over to 2027. You’ll need to select a new contribution amount if you want to hit the new, higher HSA maximum for 2027.
  • You will be enrolled automatically in the applicable short-term disability plan (VDI for California employees and STD for all others).

Tips for using the enrollment site

  • When you visit PlanSource during Open Enrollment, you’ll need to create a new password, even if you’ve visited the site recently.
  • Enter your temporary password, which is a combination of the year of your birth and the last four digits of your Social Security number, without spaces. For example, if you were born in 1980 and your Social Security number is 123-45-6789, your temporary password would be: 19806789.
  • After you enter your temporary password on the site, you’ll be asked to create a new password.
  • The enrollment site will display your benefit options with a button that says View/Change (if you have an election carrying over from 2026) or Explore (if you do not yet have an election for 2027). Click the button to see your benefit plan choices.
  • For each benefit, click the desired button: Choose Plan, Keep This Plan, or Decline Coverage.
  • After you make your plan choice, click the Let’s Continue button.
  • Be sure to add your dependents to each plan as you select your benefits. Simply adding dependents to PlanSource in step 2 does not enroll them in benefits. To ensure that each family member is enrolled, review Family Covered under each benefit.
  • You must click Checkout at the bottom of the page to save your benefit elections and complete your enrollment.
  • At checkout, request that a confirmation statement be sent to your work and personal email addresses. 

Password reset

All PlanSource passwords will be reset to the new-hire password before Open Enrollment. You’ll need to create a new password.
