Other benefits — such as the Employee Assistance Program (EAP), paid time off, and holidays — add substantial value to the overall benefits program. This booklet highlights key features of the employee benefits program that can answer many of your questions. Please review this booklet carefully and discuss the various plans with your family so you can make responsible enrollment elections. If you have any questions, contact Human Resources at 713-986-4454. As you make your benefit choices, give careful thought to what your future benefit needs will be. Your records of past medical expenses may help you choose the benefits that are best for you. This is your ONLY opportunity to enroll or re-enroll in benefits unless you experience a Qualifying Life Event (QLE). QLEs include the loss of your spouse’s coverage, marriage or divorce, birth or adoption of a child, or death of a dependent. Changes can be made in Paycom Self Service by using your Paycom user ID and password. Contact Human Resources for assistance.

Availability of Summary Health Information Your benefits program offers four medical coverage plan options. To help you compare your plan options and make an informed decision, a Summary of Benefits and Coverage (SBC) for each plan is available in the Paycom self service portal. A paper copy is also available by contacting Human Resources.

Eligibility

You are eligible for benefits if you are a regular, full-time employee working an average of 30 hours per week. If you are an exempt employee, you are eligible to participate on the date of hire. If you are a non-exempt employee, you are eligible to participate on the first of the month following 60 days of active employment. You may also enroll eligible dependents for benefits coverage. The cost to you for dependent coverage will vary depending on the number of dependents you enroll and the particular plans you choose. When covering dependents, you must select the same plans for your dependents as you select for yourself. You may elect coverage for yourself only, or you can include your eligible dependent(s) for coverage:

Making Changes During the Year Your benefit elections remain in effect for the entire plan year until the following Open Enrollment. You may only change coverage during the plan year if you have a QLE such as marriage, divorce, birth or adoption,

Our medical coverage is provided through UnitedHealthcare (UHC). You have a choice of four plans: the Nexus ACO, Choice EPO, Choice Plus PPO, and the HDHP. Two of our medical plans provide access to both in-network and out-of-network providers: Choice Plus PPO and HDHP. You will get better discounts and pay less money by remaining in-network for health care services. All out-of-network services are subjected to Reasonable and Customary (R&C) limitations. This means you are responsible for all charges over this allowance.

the difference if a provider’s fees are above the R&C limits.

Nexus ACO Plan z

Houston, TX – Memorial Hermann Network Only

Austin, TX – Seton Health Alliance Network Only

Orlando, FL – Florida Hospital Network Only

The Nexus ACO option requires you to seek medical services with a Memorial Hermann network physician or facility if you reside in Houston, a Seton Health Alliance network physician or facility if you reside in Austin, or a Florida Hospital network physician or facility if you reside in Orlando. You can reduce your office visit copay as well as reduce your calendar year deductible if you choose this medical option and ONLY utilize contracted network physicians and facilities. If you elect this plan and do not reside in Houston, Austin, or Orlando, you must seek medical services with a UHC Premium Tier 1 provider or facility to receive the Premium Tier 1 benefits, or a provider or facility in the Choice EPO network to receive non-premium Tier 1 benefits.

Choice EPO Plan z

UHC Choice Network

This option is an Exclusive Provider Organization (EPO) plan and provides a larger network of UHC providers and facilities through the UHC Choice network. If you seek services outside of this network, you will be responsible for all billed charges.

Choice Plus POS Plan z

UHC Choice Plus Network

The Point of Service (POS) plan is similar to a Preferred Provider Organization (PPO) plan and allows you the choice of in-network or out-of-network providers. If you choose in-network providers, the benefit will allow for lower deductible, coinsurance, and out-of-pocket limits than that of out-of-network providers and facilities. However, if you have an out-of-network provider that you prefer to use, benefits will be paid on a portion of these services.

HDHP Plan z

UHC Choice Plus Network

The High Deductible Health Plan (HDHP) is also similar to the PPO in that you have the option to choose any provider when you need care. However, in exchange for a lower per-paycheck cost, you must satisfy a higher deductible that applies to almost all health care expenses, including those for prescription drugs. Once your deductible has been met, you will continue to pay a prescription copay until your out-of-pocket maximum is met, then the plan pays 100%.

NOTE: Precertification is required in advance of a scheduled service such as hospitalization or surgical procedures. If you are in-network, your provider is responsible for this precertification. If you are out-of-network, you are responsible for your own precertification. In addition, mental health or substance abuse treatment, as well as certain outpatient procedures, also require this precertification. Failure to precertify while using an out-of-network provider will result in a reduction in benefits.

Prescription Drugs Your prescription drug coverage is provided through UHC and helps manage your prescription drug costs with discounts on certain brand name drugs. The UHC Rx Clinical Management Program may have requirements for certain medications. Please check the UHC Advantage Prescription Drug List for your specific medications to confirm coverage. You generally will pay the lowest copayment when using generics. If a generic is not available, ask your doctor to consider prescribing a brand-name medicine from your formulary list. These brand-name medicines are available at a lower copayment and may provide cost savings to you. Choosing brand-name medicines not on your formulary list may result in a higher copayment. What is the difference between generic, formulary, non-formulary, and specialty drugs? z

Generic Drugs (Tier 1) are cost-effective alternatives to brand-name medicines.

Formulary Brand-Name Drugs (Tier 2) are prescription medications selected by a committee of physicians and pharmacists. The committee chooses the Preferred (Formulary) products using strict criteria such as safety and efficacy (usually does not have a generic alternative).

Non-formulary Brand-Name Drugs (Tier 3) are all other brand-name drugs not included on the Tier 2 list.

Specialty Brand Drugs (Tier 4) are prescription medications that are used to treat complex or rare conditions.

For a complete list of the formulary (preferred brand- name) drugs, go to www.myuhc.com.

Home Delivery For maintenance medications, you can use the UHC Rx home delivery service and receive a 90day supply for a two-month copayment. Employees who are taking maintenance medications — like cholesterol and diabetes medications — benefit by using this plan feature. For more information, please call UHC at the phone number on the back of your ID card. PRESCRIPTIONS Tier 1 Generic

Health Savings Account

Enrolling in the HDHP medical plan provides eligibility to open a Health Savings Account (HSA). An HSA is a personal savings account you can use to pay qualified out-of-pocket medical expenses with pretax dollars. You — not Geospace Technologies — own and control the money in your HSA. The money you deposit is not taxed, and you can invest it in stocks, bonds, and mutual funds. The money in this account (including interest and investment earnings) grows tax-free, and as long as the funds are used to pay for qualified medical expenses, they are spent

If you open and contribute to the HSA through Health Equity, an account with Wells Fargo will be opened for you. A QuickStart Guide will be emailed to you, and a Health Equity debit card will be mailed to your address on record. Review both items for important information on how the HSA works. Note: All HSA participants must comply with the Customer Identification Program (CIP), a required regulation through Section 326 of the USA Patriot Act. The CIP regulation requires institutions, such as Wells Fargo, to verify the identity of all HSA customers including Social Security number, name, date of birth, and physical address (cannot be a P.O. Box). If Wells Fargo is unable to verify the identifying information provided, Wells Fargo will send a letter to the account holder address on file requesting additional documentation to satisfy CIP. The account cannot be opened until CIP is verified.

HDHP and HSA FAQ

Q What is the HDHP medical plan Geospace Technologies offers? A It is an IRS-qualified High Deductible Health Plan allowing you the benefit of a Health

Savings Account. Both employees and employers can make contributions to this account.

Q What is an HSA? A An HSA is a savings account that allows you to save and pay for qualified health expenses for you and your dependents on a tax-free basis. Geospace Technologies will withhold

elected contributions from your payroll and deposit the pretax money into your HSA. For 2026-2027, Geospace Technologies will double your contribution up to $500 annually for Employee Only coverage and up to $750 annually for Family coverage into the HSA.

Q How do I open an HSA bank account? A If you elect to contribute to the HSA when completing your online enrollment through

Paycom, a request will be sent to Wells Fargo on your behalf for an account to be opened. You will be required to complete an online application before any contributions will be deposited into your account. You will be notified via mail on the steps to take to complete your application online.

Q Who is eligible for an HSA? A You must be enrolled in an IRS-qualified HDHP. You must not be covered by another

medical plan unless the other medical plan is also a qualified HDHP. You must not be enrolled in Medicare coverage.

Q Does my HSA earn interest? A Yes, once your account reaches a certain threshold, your HSA may earn interest and the interest is non-taxable.

Q How do I pay for claims through my HSA? A You will receive a debit card from Health Equity. You can use this card for HSA eligible

expenses at certain qualified locations. There are additional ways to utilize your money with Health Equity. Contact Human Resources for additional information.

qualified health expenses from my HSA?

A Yes, you will be subject to your regular income tax rate and a 20% penalty.

Q Do I have to prove my expenses are qualified health expenses?

A You are responsible for saving receipts in the event the IRS audits your tax return.

Q If I do not spend all of the money in my HSA, do I lose it?

A No, you own your HSA. Any unused

funds are yours and remain in your HSA. You can use this money for qualified health-related expenses throughout your life.

Q If I leave Geospace Technologies, do I lose the money in my HSA?

A No, you own your HSA and the money is yours to keep, including the money

Geospace Technologies has deposited on your behalf. You can use this money for qualified health-related expenses throughout your life.

Mark has family coverage with an HDHP.

His total pretax contribution for the year is $6,850.

Every pay period, he puts $259.61 into his HSA.

Mark’s federal tax bracket is 28%.1 Mark lives in Illinois, where HSA contributions are not taxed.2 His total federal income tax savings on contributions this year are ($6,850 × 0.28) + ($6,850 × 0.03) = $2,123.50.

Please see www.irs.gov to determine your tax bracket.

Hypothetical example assumes a state tax rate of 3% in Illinois. While HSAs were created by the federal government, states can choose to follow the federal tax treatment guidelines or establish their own. Some states have chosen to tax HSA contributions.

Voluntary Dental Coverage Our dental plans through Guardian Life help you maintain good dental health through affordable options for preventive care, including regular checkups and other dental work. Premium contributions for dental will be deducted from your paycheck on a pretax basis. You have the choice between a Dental Health Management Organization (DHMO) and a passive Dental Preferred Provider Organization (DPPO) plan.

DPPO Plan The DPPO plan allows you to use ANY dentist. If you receive care from an in-network dentist, you will save money through negotiated network discounts. Using an in-network dentist reduces your share of dental costs, and your dentist agrees not to bill you for covered services over usual and customary limits. Remember, the use of an in-network dentist is OPTIONAL.

DHMO Plan

DPPO

The DHMO plan requires that you select a dentist or dental group for all of your family members when you enroll. This dentist or dental group must provide ALL dental services; otherwise, there will be no benefit. When you go to your selected network dentist, the Schedule of Benefits and subscriber copayments determine your payment. If the dentist requires a procedure that is not listed on the schedule, it will not be covered on this plan.

Health Care FSA A Health Care FSA enables you to take control of your out-of-pocket health care spending by contributing pretax money to your account to pay for everyday eligible expenses. The result can be substantial savings on products and services not covered by your medical, dental, or vision plan such as copayments, coinsurance deductibles, prescription expenses, lab exams, tests, contact lenses, eyeglasses, and more. A complete list of qualified expenses can be found in publication 502 on the IRS website. When you incur the expense, you will be reimbursed the full amount at that time. You can contribute up to $3,400 annually in your Health Care FSA.

Limited Purpose FSA The Limited Purpose FSA is for employees enrolled in the HDHP with HSA medical plan option. The Limited Purpose FSA works the same way as the standard Health Care FSA does: pretax, “use it or lose it” elections, and expenses must occur within the plan year. However, with the Limited Purpose FSA, you can only submit claims for eligible vision and dental expenses. You can contribute up to $3,400 annually to a Limited Purpose FSA.

How to Use the Debit Card The FSA debit card allows you to pay for eligible health care expenses at the point of service and deducts funds directly from your Health Care or Limited Purpose FSA. This allows you to avoid waiting for reimbursement. The debit card is automatically sent to new participants. If you are already a participant, keep your current card. You may use your FSA debit card at locations such as doctor and dentist offices, pharmacies, and vision service providers. The card cannot be used at locations that do not offer services under the plan, unless the provider has also complied with IRS regulations. Should you attempt to use the card at an ineligible location, the swipe transaction will be denied. Should you need to submit a receipt for substantiation, you will receive an email or Receipt Notification. Always retain receipts for your records.

Disability Programs If you suddenly become ill or are involved in an accident and are unable to work, it is easy to fall behind on your rent or mortgage, car payment, and other expenses. That is why a salary replacement plan is an important benefit for you and your family. Geospace Technologies provides full-time employees with Short Term Disability (STD) and Long Term Disability (LTD) income benefits, and pays the full cost of this coverage. In the event you become disabled from a non-work-related injury or sickness, disability income benefits are provided as a source of income. Disability coverage is provided through Guardian Life.

STD Insurance STD coverage pays a percentage of your salary if you are temporarily disabled and unable to work due to an illness, non-work-related injury, or pregnancy. STD benefits are NOT payable if the disability is due to a job-related injury or illness. If you have an STD claim, call Guardian Life at 888-262-5670 to initiate the process. Claims must be submitted and verified by Guardian Life for you to be paid STD. Claims can take 5-7 days to process.

Required Notices Women’s Health and Cancer Rights Act of 1998 In October 1998, Congress enacted the Women’s Health and Cancer Rights Act of 1998. This notice explains some important provisions of the Act. Please review this information carefully. As specified in the Women’s Health and Cancer Rights Act, a plan participant or beneficiary who elects breast reconstruction in connection with a mastectomy is also entitled to the following benefits: z

All stages of reconstruction of the breast on which the mastectomy was performed;

Surgery and reconstruction of the other breast to produce a symmetrical appearance; and

Prostheses and treatment of physical complications of the mastectomy, including lymphedema.

Health plans must determine the manner of coverage in consultation with the attending physician and the patient. Coverage for breast reconstruction and related services may be subject to deductibles and coinsurance amounts that are consistent with those that apply to other benefits under the plan.

Special Enrollment Rights This notice is being provided to ensure that you understand your right to apply for group health insurance coverage. You should read this notice even if you plan to waive coverage at this time.

Loss of Other Coverage or Becoming Eligible for Medicaid or a state Children’s Health Insurance Program (CHIP) If you are declining coverage for yourself or your dependents because of other health insurance or group health plan coverage, you may be able to later enroll yourself and your dependents in this plan if you or your dependents lose eligibility for that other coverage (or if the employer stops contributing toward your or your dependents’ other coverage). However, you must enroll within 31 days after your or your dependents’ other coverage ends (or after the employer that sponsors that coverage stops contributing toward the other coverage). If you or your dependents lose eligibility under a Medicaid plan or CHIP, or if you or your dependents become eligible for a subsidy under Medicaid or CHIP, you may be able to enroll yourself and your dependents in this plan. You must provide notification within 60 days after you or your dependent is terminated from, or determined to be eligible for, such assistance.

Marriage, Birth or Adoption If you have a new dependent as a result of a marriage, birth, adoption, or placement for adoption, you may be able to enroll yourself and your dependents. However, you must enroll within 31 days after the marriage, birth, or placement for adoption.

For More Information or Assistance To request special enrollment or obtain more information, contact: Geospace Technologies Human Resources 7007 Pinemont Houston, TX 77292 713-986-4454

Your Prescription Drug Coverage and Medicare Please read this notice carefully and keep it where you can find it. This notice has information about your current prescription drug coverage with Geospace Technologies and about your options under Medicare’s prescription drug coverage. This information can help you decide whether or not you want to enroll in a Medicare drug plan. Information about where you can get help to make decisions about your prescription drug coverage is at the end of this notice. If neither you nor any of your covered dependents are eligible for or have Medicare, this notice does not apply to you or the dependents, as the case may be. However, you should still keep a copy of this notice in the event you or a dependent should qualify for coverage under Medicare in the future. Please note, however, that later notices might supersede this notice. 1.

Medicare prescription drug coverage became available in 2006 to everyone with Medicare. You can get this coverage through a Medicare Prescription Drug Plan or a Medicare Advantage Plan that offers prescription drug coverage. All Medicare prescription drug plans provide at least a standard level of coverage set by Medicare. Some plans may also offer more coverage for a higher monthly premium.

Geospace Technologies has determined that the prescription drug coverage offered by the Geospace Technologies medical plan is, on average for all plan participants, expected to pay out as much as the standard Medicare prescription drug coverage pays and is considered Creditable Coverage. The HSA plan is not considered Creditable Coverage.

Because your existing coverage is, on average, at least as good as standard Medicare prescription drug coverage, you can keep this coverage and not pay a higher premium (a penalty) if you later decide to enroll in a Medicare prescription drug plan, as long as you later enroll within specific time periods. You can enroll in a Medicare prescription drug plan when you first become eligible for Medicare. If you decide to wait to enroll in a Medicare prescription drug plan, you may enroll later, during Medicare Part D’s annual enrollment period, which runs each year from October 15 through December 7 but as a general rule, if you delay your enrollment in Medicare Part D after first becoming eligible to enroll, you may have to pay a higher premium (a penalty). You should compare your current coverage, including which drugs are covered at what cost, with the coverage and cost of the plans offering Medicare prescription drug coverage in your area. See the Plan’s summary plan description for a summary of the Plan’s prescription drug coverage. If you don’t have a copy, you can get one by contacting Geospace Technologies at the phone number or address listed at the end of this section. If you choose to enroll in a Medicare prescription drug plan and cancel your current Geospace Technologies prescription drug coverage, be aware that you and your dependents may not be able to get this coverage back. To regain coverage, you would have to re-enroll in the Plan, pursuant to the Plan’s eligibility and enrollment rules. You should review the Plan’s summary plan description to determine if and when you are allowed to add coverage. If you cancel or lose your current coverage and do not have prescription drug coverage for 63 days or longer prior to enrolling in the Medicare prescription drug coverage, your monthly premium will be at least 1% per month greater for every month that you did not have coverage for as long as you have Medicare prescription drug coverage. For example, if nineteen months lapse without coverage, your premium will always be at least 19% higher than it would have been without the lapse in coverage.

For more information about this notice or your current prescription drug coverage: Contact the Human Resources Department at 713-986-4454. NOTE: You will receive this notice annually and at other times in the future, such as before the next period you can enroll in Medicare prescription drug coverage and if this coverage changes. You may also request a copy.

You will get a copy of the handbook in the mail every year from Medicare. You may also be contacted directly by Medicare prescription drug plans.

Information about this extra help is available from the Social Security Administration (SSA) online at www. socialsecurity.gov, or you can call them at 800772-1213. TTY users should call 800-325-0778. Remember: Keep this Creditable Coverage notice. If you enroll in one of the new plans approved by Medicare which offer prescription drug coverage, you may be required to provide a copy of this notice when you join to show whether or not you have maintained creditable coverage and whether or not you are required to pay a higher premium (a penalty).

describes how your protected health information may be used or disclosed to carry out treatment, payment, or health care operations, or for any other purposes that are permitted or required by law. We are required to provide this Notice of Privacy Practices to you pursuant to HIPAA. The HIPAA Privacy Rule protects only certain medical information known as “protected health information.” Generally, protected health information (PHI) is health information, including demographic information, collected from you or created or received by a health care provider, a health care clearinghouse, a health plan, or your employer on behalf of a group health plan, from which it is possible to individually identify you and that relates to: 1.

Your past, present, or future physical or mental health or condition;

The provision of health care to you; or

The past, present, or future payment for the provision of health care to you.

I. Contact Information If you have any questions about this Notice or about our privacy practices, and for any correspondence or requests related to the contents of this Notice, please contact: Geospace Technologies Human Resources 7007 Pinemont Houston, TX 77292 713-986-4454

III. Our Responsibilities We are required by law to: 1.

maintain the privacy of your PHI;

provide you with certain rights with respect to your PHI;

provide you with a copy of this Notice of our legal duties and privacy practices with respect to your PHI; and

follow the terms of the Notice that is currently in effect.

We reserve the right to change the terms of this Notice and to make new provisions regarding your PHI that we maintain, as allowed or required by law. If we make any material change to this Notice, we will provide you with a copy of our revised Notice of Privacy Practices.

IV. How We May Use and Disclose Your PHI Under the law, we may use or disclose your PHI under certain circumstances without your permission. The following categories describe the different ways that we may use and disclose your PHI. For each category of uses or disclosures we will explain what we mean and present some examples. Not every use or disclosure in a category will be listed. However, all of the ways we are permitted to use and disclose information will fall within one of the categories. Note that we will use and disclose PHI as described below unless otherwise prohibited or restricted by applicable state or other law, and that information can lose its protected status as PHI once re-disclosed by a recipient. For Treatment. When and as appropriate, we may use or disclose medical information about you to facilitate medical treatment or services by health care providers. We may disclose medical information about you to providers, including doctors, nurses, technicians, medical students, or other hospital personnel who are involved in taking care of you. For example, we might disclose information about you with physicians who are treating you. For Payment. We may use or disclose your protected health information to determine your eligibility for Plan benefits, to facilitate payment for the treatment and services you receive from health care providers, to determine benefit responsibility under the Plan, or to coordinate Plan coverage. For example, we may tell your health care provider about your medical history to determine whether a particular treatment is experimental, investigational, or medically necessary, or to determine whether the Plan will cover the treatment. We may also share your protected health information with a utilization review or pre-certification service provider. Likewise, we may share your protected health information with another entity to assist with the adjudication or subrogation of health claims or to another health plan to coordinate benefit payments. For Health Care Operations. We may use and disclose your protected health information for other Plan operations. These uses and disclosures are necessary to run the Plan. For example, we may use medical information in connection with conducting quality assessment and improvement activities; underwriting, premium rating, and other activities relating to Plan coverage; submitting claims for stop-loss (or excess-loss) coverage; conducting or arranging for medical review, legal services, audit services, and fraud and abuse detection programs; business planning

37 2026–2027 EMPLOYEE BENEFITS GUIDE

and development such as cost management; and business management and general Plan administrative activities. However, we will not use your genetic information for underwriting purposes. Substance Use Disorder (SUD) Treatment Information. Some of your health information may be part of a SUD patient record and subject to additional protections under federal law (42 CFR Part 2) governing confidentiality of SUD patient records. If we receive or maintain any information about you from a SUD treatment program that is covered by 42 CFR Part 2 (a “Part 2 Program”) through a general consent you provide to the Part 2 Program to use and disclose the SUD patient record for purposes of treatment, payment or health care operations, we may use and disclose your SUD patient record for treatment, payment and health care operations purposes as described in this Notice. If we receive or maintain your SUD patient record through specific consent you provide to us or another third party, we will use and disclose your SUD patient record only as expressly permitted by you in your consent as provided to us. In no event will we use or disclose your SUD patient record, or testimony that describes the information contained in your SUD patient record, in any civil, criminal, administrative, or legislative proceedings by any Federal, State, or local authority, against you, unless authorized by your consent or the order of a court after it provides you notice of the court order. To Business Associates. We may contract with individuals or entities known as Business Associates to perform various functions on our behalf or to provide certain types of services. In order to perform these functions or to provide these services, Business Associates will receive, create, maintain, transmit, use, and/or disclose your PHI, but only after they agree in writing with us to implement appropriate safeguards regarding your PHI. For example, we may disclose your PHI to a Business Associate to process your claims for Plan benefits or to provide support services, such as utilization management, pharmacy benefit management, or subrogation, but only after the Business Associate enters into a Business Associate contract with us. Treatment Alternatives or Health-Related Benefits and Services. We may use and disclose your protected health information to send you information about treatment alternatives or other health-related benefits and services that might be of interest to you. As Required by Law. We will disclose your PHI when required to do so by federal, state, or local

law. For example, we may disclose your PHI when required by national security laws or public health disclosure laws. To Avert a Serious Threat to Health or Safety. We may use and disclose your PHI when necessary to prevent a serious threat to your health and safety, or the health and safety of the public or another person. Any disclosure, however, would only be to someone able to help prevent the threat. For example, we may disclose your PHI in a proceeding regarding the licensure of a physician. To Plan Sponsors. For the purpose of administering the plan, we may disclose PHI to certain employees of the Employer. However, those employees will only use or disclose that information as necessary to perform plan administration functions or as otherwise required by HIPAA, unless you have authorized further disclosures. Your PHI cannot be used for employment purposes without your specific authorization.

V. Special Situations In addition to the above, the following categories describe other possible ways that we may use and disclose your PHI without your specific authorization. For each category of uses or disclosures, we will explain what we mean and present some examples. Not every use or disclosure in a category will be listed. However, all of the ways we are permitted to use and disclose information will fall within one of the categories. Organ and Tissue Donation. If you are an organ donor, we may release your PHI after your death to organizations that handle organ procurement or organ, eye, or tissue transplantation or to an organ donation bank, as necessary to facilitate organ or tissue donation and transplantation. Military. If you are a member of the armed forces, we may release your PHI as required by military command authorities. We may also release PHI about foreign military personnel to the appropriate foreign military authority. Workers’ Compensation. We may release your PHI for workers’ compensation or similar programs, but only as authorized by, and to the extent necessary to comply with, laws relating to workers’ compensation and similar programs that provide benefits for work-related injuries or illness.

Health Oversight Activities. We may disclose your PHI to a health oversight agency for activities authorized by law. These oversight activities include, for example, audits, investigations, inspections, and licensure. These activities are necessary for the government to monitor the health care system, government programs, and compliance with civil rights laws. Lawsuits and Disputes. If you are involved in a lawsuit or a dispute, we may disclose your PHI in response to a court or administrative order. We may also disclose your PHI in response to a subpoena, discovery request, or other lawful process by someone involved in a legal dispute, but only if efforts have been made to tell you about the request or to obtain a court or administrative order protecting the information requested.

We are also required, when requested, to provide you with an accounting of most disclosures of your PHI if the disclosure was for reasons other than for payment, treatment, or health care operations, and if the PHI was not disclosed pursuant to your individual authorization.

VII. Other Disclosures Personal Representatives. We will disclose your PHI to individuals authorized by you, or to an individual designated as your personal representative, attorney-in-fact, etc., so long as you provide us with a written notice/authorization and any supporting documents (i.e., power of attorney). Note: Under the HIPAA privacy rule, we do not have to disclose information to a personal representative if we have a reasonable belief that: 1.

You have been, or may be, subject to domestic violence, abuse, or neglect by such person; or

Treating such person as your personal representative could endanger you; and

In the exercise of professional judgment, it is not in your best interest to treat the person as your personal representative.

Spouses and Other Family Members. With only limited exceptions, we will send all mail to the employee. This includes mail relating to the employee’s spouse and other family members who are covered under the Plan and includes mail with information on the use of Plan benefits by the employee’s spouse and other family members and information on the denial of any Plan benefits to the employee’s spouse and other family members. If a person covered under the Plan has requested Restrictions or Confidential Communications (see below under “Your Rights”), and if we have agreed to the request, we will send mail as provided by the request for Restrictions or Confidential Communications. Authorizations. Other uses or disclosures of your PHI not described above will only be made with your written authorization. For example, in general and subject to specific conditions, we will not use or disclose your psychiatric notes; we will not use or disclose your PHI for marketing; and we will not sell your PHI, unless you give us a written authorization. You may revoke written authorizations at any time, so long as the revocation is in writing. Once we receive your written revocation, it will only be effective for future uses and disclosures. It will not be effective for any information that may have been used or disclosed in reliance upon the written authorization and prior to receiving your written revocation.

VIII. Your Rights You have the following rights with respect to your PHI: Right to Inspect and Copy. You have the right to inspect and copy certain PHI that may be used to make decisions about your Plan benefits. If the information you request is maintained electronically, and you request an electronic copy, we will provide a copy in the electronic form and format you request, if the information can be readily produced in that form and format; if the information cannot be readily produced in that form and format, we will work with you to come to an agreement on form and format. If we cannot agree on an electronic form and format, we will provide you with a paper copy. To inspect and copy your PHI, you must submit your request in writing. If you request a copy of the information, we may charge a reasonable fee for the costs of copying, mailing, or other supplies associated with your request.

We may deny your request to inspect and copy in certain very limited circumstances. If you are denied access to your medical information, you may request that the denial be reviewed by submitting a written request. Right to Amend. If you feel that the PHI we have about you is incorrect or incomplete, you may ask us to amend the information. You have the right to request an amendment for as long as the information is kept by or for the Plan. To request an amendment, your request must be made in writing. In addition, you must provide a reason that supports your request. We may deny your request for an amendment if it is not in writing or does not include a reason to support the request. In addition, we may deny your request if you ask us to amend information that: 1.

is not part of the medical information kept by or for the Plan;

was not created by us, unless the person or entity that created the information is no longer available to make the amendment;

is not part of the information that you would be permitted to inspect and copy; or

is already accurate and complete.

If we deny your request, you have the right to file a statement of disagreement with us and any future disclosures of the disputed information will include your statement. Right to an Accounting of Disclosures. You have the right to request an “accounting” of certain disclosures of your PHI. The accounting will not include (1) disclosures for purposes of treatment, payment, or health care operations; (2) disclosures made to you; (3) disclosures made pursuant to your authorization; (4) disclosures made to friends or family in your presence or because of an emergency; (5) disclosures for national security purposes; and (6) disclosures incidental to otherwise permissible disclosures. To request this list or accounting of disclosures, you must submit your request in writing. Your request must state the time period you want the accounting to cover, which may not be longer than six years before the date of the request. Your request should indicate in what form you want the list (for example, paper or electronic). The first list you request within a 12-month period will be provided free of charge. For additional lists, we may charge you for the costs of providing the list. We will notify you of the cost involved and you may choose to withdraw or modify your request at that time before any costs are incurred.

Right to Request Restrictions. You have the right to request a restriction or limitation on your PHI that we use or disclose for treatment, payment, or health care operations. You also have the right to request a limit on your PHI that we disclose to someone who is involved in your care or the payment for your care, such as a family member or friend. For example, you could ask that we not use or disclose information about a surgery that you had. Except as provided in the next paragraph, we are not required to agree to your request. However, if we do agree to the request, we will honor the restriction until you revoke it or we notify you. We will comply with any restriction request if (1) except as otherwise required by law, the disclosure is to a health plan for purposes of carrying out payment or health care operations (and is not for purposes of carrying out treatment); and (2) the PHI pertains solely to a health care item or service for which the health care provider involved has been paid in full by you or another person. To request restrictions, you must make your request in writing. In your request, you must tell us (1) what information you want to limit; (2) whether you want to limit our use, disclosure, or both; and (3) to whom you want the limits to apply-for example, disclosures to your spouse. Right to Request Confidential Communications. You have the right to request that we communicate with you about medical matters in a certain way or at a certain location. For example, you can ask that we only contact you at work or by mail. To request confidential communications, you must make your request in writing. We will not ask you the reason for your request. Your request must specify how or where you wish to be contacted. We will accommodate all reasonable requests. Right to Be Notified of a Breach. You have the right to be notified in the event that we (or a Business Associate) discover a breach of unsecured PHI. Right to a Paper Copy of This Notice. You have the right to a paper copy of this notice. You may ask us to give you a copy of this notice at any time. Even if you have agreed to receive this notice electronically, you are still entitled to a paper copy of this notice.

IX. Complaints If you believe that your privacy rights have been violated, you may file a complaint with the Plan or with the Office for Civil Rights of the United States Department of Health and Human Services. To file a complaint with the Plan, contact the person listed in the Contact Information section of this Notice. All complaints must be submitted in writing. You will not be penalized, or in any other way retaliated against, for filing a complaint with the Office for Civil Rights or with us..

Premium Assistance Under Medicaid and the Children’s Health Insurance Program (CHIP) If you or your children are eligible for Medicaid or CHIP and you’re eligible for health coverage from your employer, your state may have a premium assistance program that can help pay for coverage, using funds from their Medicaid or CHIP programs. If you or your children aren’t eligible for Medicaid or CHIP, you won’t be eligible for these premium assistance programs but you may be able to buy individual insurance coverage through the Health Insurance Marketplace. For more information, visit www.healthcare.gov. If you or your dependents are already enrolled in Medicaid or CHIP and you live in a State listed below, contact your State Medicaid or CHIP office to find out if premium assistance is available. If you or your dependents are NOT currently enrolled in Medicaid or CHIP, and you think you or any of your dependents might be eligible for either of these programs, contact your State Medicaid or CHIP office or dial 1-877-KIDS NOW or www.insurekidsnow.gov to find out how to apply. If you qualify, ask your state if it has a program that might help you pay the premiums for an employer-sponsored plan. If you or your dependents are eligible for premium assistance under Medicaid or CHIP, as well as eligible under your employer plan, your employer must allow you to enroll in your employer plan if you aren’t already enrolled. This is called a “special enrollment” opportunity, and you must request coverage within 60 days of being determined eligible for premium assistance. If you have questions about enrolling in your employer plan, contact the Department of Labor at www.askebsa.dol.gov or call 1-866-444EBSA (3272).

If you live in one of the following States, you may be eligible for assistance paying your employer health plan premiums. The following list of States is current as of January 31, 2026. Contact your State for more information on eligibility.

Continuation of Coverage Rights Under COBRA

You are protected from balance billing for: z

Emergency services – If you have an emergency medical condition and get emergency services from an out-of-network provider or facility, the most the provider or facility may bill you is your plan’s in-network cost-sharing amount (such as copayments and coinsurance). You cannot be balance billed for these emergency services. This includes services you may get after you are in stable condition, unless you give written consent and give up your protections not to be balanced billed for these poststabilization services.

Certain services at an in-network hospital or ambulatory surgical center – When you get services from an in-network hospital or ambulatory surgical center, certain providers there may be out-of-network. In these cases, the most those providers may bill you is your plan’s in-network costsharing amount. This applies to emergency medicine, anesthesia, pathology, radiology, laboratory, neonatology, assistant surgeon, hospitalist, or intensivist services. These providers cannot balance bill you and may not ask you to give up your protections not to be balance billed.

Under the Federal Consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA), if you are covered under the Geospace Technologies group health plan you and your eligible dependents may be entitled to continue your group health benefits coverage under the Geospace Technologies plan after you have left employment with the company. If you wish to elect COBRA coverage, contact your Human Resources Department for the applicable deadlines to elect coverage and pay the initial premium.

Your Rights and Protections Against Surprise Medical Bills When you get emergency care or get treated by an out-of-network provider at an in-network hospital or ambulatory surgical center, you are protected from surprise billing or balance billing.

What is “balance billing” (sometimes called “surprise billing”)? When you see a doctor or other health care provider, you may owe certain out-of-pocket costs, such as a copayment, coinsurance, and/or a deductible. You may have other costs or have to pay the entire bill if you see a provider or visit a health care facility that isn’t in your health plan’s network. “Out-of-network” describes providers and facilities that have not signed a contract with your health plan. Out-of-network providers may be permitted to bill you for the difference between what your plan agreed to pay and the full amount charged for a service. This is called “balance billing.” This amount is likely more than innetwork costs for the same service and might not count toward your annual out-of-pocket limit. “Surprise billing” is an unexpected balance bill. This can happen when you can’t control who is involved in your care—like when you have an emergency or when you schedule a visit at an innetwork facility but are unexpectedly treated by an out-of-network provider.

If you get other services at these in-network facilities, out-of-network providers cannot balance bill you, unless you give written consent and give up your protections. You are never required to give up your protections from balance billing. You also are not required to get care out-of-network. You can choose a provider or facility in your plan’s network.

When balance billing is not allowed, you also have the following protections: z

You are only responsible for paying your share of the cost (like the copayments, coinsurance, and deductibles that you would pay if the provider or facility was in-network). Your health plan will pay out-ofnetwork providers and facilities directly.

Your health plan generally must: y

Cover emergency services without requiring you to get approval for services in advance (prior authorization).

42 GEOSPACE TECHNOLOGIES

Cover emergency services by out-ofnetwork providers.

Base what you owe the provider or facility (cost-sharing) on what it would pay an in-network provider or facility and show that amount in your explanation of benefits.

Count any amount you pay for emergency services or out-of-network services toward your deductible and out-of-pocket limit.

If you believe you have been wrongly billed, you may contact your insurance provider. Visit www. cms.gov/nosurprises for more information about your rights under federal law.

New Health Insurance Marketplace Coverage Options and Your Health Coverage PART A: General Information

Even if you are offered health coverage through your employment, you may have other coverage options through the Health Insurance Marketplace (“Marketplace”). To assist you as you evaluate options for you and your family, this notice provides some basic information about the Health Insurance Marketplace.

What is the Health Insurance Marketplace? The Marketplace is designed to help you find health insurance that meets your needs and fits your budget. The Marketplace offers “one-stop shopping” to find and compare private health insurance options in your geographic area.

Can I Save Money on my Health Insurance Premiums in the Marketplace? You may qualify to save money and lower your monthly premium and other out-of-pocket costs, but only if your employer does not offer coverage, or offers coverage that is not considered affordable for you and doesn’t meet certain minimum value standards (discussed below). The savings on your premium that you’re eligible for depends on your household income. You may also be eligible for a tax credit that lowers your costs.

Does Employment-Based Health Coverage Affect Eligibility for Premium Savings through the Marketplace? Yes. If you have an offer of health coverage from your employer that is considered affordable for you and meets certain minimum value standards, you will not be eligible for a tax credit,

or advance payment of the tax credit, for your Marketplace coverage and may wish to enroll in your employment-based health plan. However, you may be eligible for a tax credit, and advance payments of the credit that lowers your monthly premium, or a reduction in certain cost-sharing, if your employer does not offer coverage to you at all or does not offer coverage that is considered affordable for you or meet minimum value standards. If your share of the premium cost of all plans offered to you through your employment is more than 9.12%1 of your annual household income, or if the coverage through your employment does not meet the “minimum value” standard set by the Affordable Care Act, you may be eligible for a tax credit, and advance payment of the credit, if you do not enroll in the employment-based health coverage. For family members of the employee, coverage is considered affordable if the employee’s cost of premiums for the lowest-cost plan that would cover all family members does not exceed 9.12% of the employee’s household income.1, 2 Note: If you purchase a health plan through the Marketplace instead of accepting health coverage offered through your employment, then you may lose access to whatever the employer contributes to the employment-based coverage. Also, this employer contribution -as well as your employee contribution to employment-based coverage- is generally excluded from income for federal and state income tax purposes. Your payments for coverage through the Marketplace are made on an after-tax basis. In addition, note that if the health coverage offered through your employment does not meet the affordability or minimum value standards, but you accept that coverage anyway, you will not be eligible for a tax credit. You should consider all of these factors in determining whether to purchase a health plan through the Marketplace.

When Can I Enroll in Health Insurance Coverage through the Marketplace? You can enroll in a Marketplace health insurance plan during the annual Marketplace Open Enrollment Period. Open Enrollment varies by state but generally starts November 1 and continues through at least December 15. Outside the annual Open Enrollment Period, you can sign up for health insurance if you qualify for a Special Enrollment Period. In general, you qualify for a Special Enrollment Period if you’ve had certain qualifying life events, such as getting married, having a baby, adopting a child, or losing eligibility for other health coverage. Depending on your Special Enrollment Period type, you

may have 60 days before or 60 days following the qualifying life event to enroll in a Marketplace plan. There is also a Marketplace Special Enrollment Period for individuals and their families who lose eligibility for Medicaid or Children’s Health Insurance Program (CHIP) coverage on or after March 31, 2023, through July 31, 2024. Since the onset of the nationwide COVID-19 public health emergency, state Medicaid and CHIP agencies generally have not terminated the enrollment of any Medicaid or CHIP beneficiary who was enrolled on or after March 18, 2020, through March 31, 2023. As state Medicaid and CHIP agencies resume regular eligibility and enrollment practices, many individuals may no longer be eligible for Medicaid or CHIP coverage starting as early as March 31, 2023. The U.S. Department of Health and Human Services is offering a temporary Marketplace Special Enrollment period to allow these individuals to enroll in Marketplace coverage. Marketplace-eligible individuals who live in states served by HealthCare.gov and either- submit a new application or update an existing application on HealthCare.gov between March 31, 2023 and July 31, 2024, and attest to a termination date of Medicaid or CHIP coverage within the same time period, are eligible for a 60-day Special Enrollment Period. That means that if you lose Medicaid or CHIP coverage between March 31, 2023, and July 31, 2024, you may be able to enroll in Marketplace coverage within 60 days of when you lost Medicaid or CHIP coverage. In addition, if you or your family members are enrolled in Medicaid or CHIP coverage, it is important to make sure that your contact information is up to date to make sure you get any information about changes to your eligibility. To learn more, visit www.HealthCare.gov or call the Marketplace Call Center at 1-800-318-2596. TTY users can call 1-855-889-4325.

What about Alternatives to Marketplace Health Insurance Coverage? If you or your family are eligible for coverage in an employment-based health plan (such as an employer-sponsored health plan), you or your family may also be eligible for a Special Enrollment Period to enroll in that health plan in certain circumstances, including if you or your dependents were enrolled in Medicaid or CHIP coverage and lost that coverage. Generally, you have 60 days after the loss of Medicaid or CHIP coverage to enroll in an employmentbased health plan, but if you and your family lost eligibility for Medicaid or CHIP coverage between March 31, 2023 and July 10, 2023, you

You are not eligible for health insurance coverage through this employer. You and your family may be able to obtain health coverage through the Marketplace, with a new kind of tax credit that lowers your monthly premiums and with assistance for out-of-pocket costs. 1

Indexed annually; see https://www.irs.gov/pub/irs-drop/rp-22-34.pdf for 2023.

An employer-sponsored or other employment-based health plan meets the “minimum value standard” if the plan’s share of the total allowed benefit costs covered by the plan is no less than 60 percent of such costs. For purposes of eligibility for the premium tax credit, to meet the “minimum value standard,” the health plan must also provide substantial coverage of both inpatient hospital services and physician services. 2
