EXPONENT, INC.

NOTES TO UNAUDITED CONDENSED CON SOLIDATED FINANCIAL STATEMENTS

Note 1: Basis of Presentation

Exponent, Inc. (referred to as the “Company” or “Exponent”) is an engineering and scientific consulting firm that provides solutions to complex problems. The Company operates on a 52-53 week fiscal year ending on the Friday closest to the last day of December.

The accompanying unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X promulgated by the U.S. Securities and Exchange Commission. Accordingly, they do not contain all the information and notes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments which are necessary for the fair presentation of the condensed consolidated financial statements have been included and all such adjustments are of a normal and recurring nature. The operating results for the three and six months ended July 3, 2026 are not necessarily representative of the results of future quarterly or annual periods. The following information should be read in conjunction with the audited consolidated financial statements and accompanying notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended January 2, 2026, which was filed with the U.S. Securities and Exchange Commission on February 27, 2026.

The unaudited condensed consolidated financial statements include the accounts of Exponent and its subsidiaries, which are all wholly owned. All intercompany accounts and transactions have been eliminated in consolidation.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. Items subject to such estimates and assumptions include accounting for revenue recognition and estimating the allowance for contract losses and doubtful accounts. Actual results could differ from those estimates.

Recent Accounting Pronouncement Not Yet Adopted

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (subtopic 220-40), which requires disclosure of disaggregation of certain relevant expenses included in the statements of operations on an annual and interim basis. ASU 2024-03 will be effective for our annual periods beginning January 2, 2027 and interim periods beginning January 1, 2028. The amendments must be applied retrospectively, and early adoption is permitted. The Company is evaluating the effect that this standard may have on its consolidated financial statements and related disclosures.

Note 2: Revenue Recognition

Substantially all of the Company’s engagements are performed under time and materials or fixed-price arrangements. For time and materials contracts, the Company utilizes the practical expedient under Accounting Standards Codification 606 – Revenue from Contracts with Customers, which states if an entity has a right to consideration from a customer in an amount that corresponds directly with the value of the entity’s performance completed to date (for example, a service contract in which an entity bills a fixed amount for each hour of service provided) then the entity may recognize revenue in the amount to which the entity has a right to invoice.

- 9 -

The following table discloses the percent of the Company’s revenue generated from time and materials contracts:

|  | Three Months Ended |  |  | Six Months Ended |
|  | July 3, 2026 |  |  | July 4, 2025 |  |  | July 3, 2026 |  |  | July 4, 2025 |
Engineering & Other Scientific |  |  | 68 | % |  |  | 65 | % |  |  | 65 | % |  |  | 66 | %
Environmental and Health |  |  | 12 | % |  |  | 15 | % |  |  | 13 | % |  |  | 14 | %
Total time and materials revenues |  |  | 80 | % |  |  | 80 | % |  |  | 78 | % |  |  | 80 | %

For fixed-price contracts, the Company recognizes revenue over time because of the continuous transfer of control to the customer. The customer typically controls the work in process as evidenced either by contractual termination clauses or by the Company’s rights to payment for work performed to date to deliver services that do not have an alternative use to the Company. Revenue for fixed-price contracts is recognized based on the relationship of incurred labor hours at standard rates to the Company’s estimate of the total labor hours at standard rates it expects to incur over the term of the contract. The Company believes this methodology achieves a reliable measure of the revenue from the consulting services it provides to its customers under fixed-price contracts given the nature of the consulting services the Company provides.

The following table discloses the percent of the Company’s revenue generated from fixed price contracts:

|  | Three Months Ended |  |  | Six Months Ended |
|  | July 3, 2026 |  |  | July 4, 2025 |  |  | July 3, 2026 |  |  | July 4, 2025 |
Engineering & Other Scientific |  |  | 19 | % |  |  | 19 | % |  |  | 21 | % |  |  | 19 | %
Environmental and Health |  |  | 1 | % |  |  | 1 | % |  |  | 1 | % |  |  | 1 | %
Total fixed price revenues |  |  | 20 | % |  |  | 20 | % |  |  | 22 | % |  |  | 20 | %

Deferred revenues represent amounts billed to clients in advance of services provided. During the second quarter of 20 26, $4,528,000 o f revenues were recognized that were included in the deferred revenue balance at April 3, 2026. During the first six months of 2026, $9,538,000 of rev enues were recognized that were included in the deferred revenue balance at January 2, 2026.

Reimbursements, including those related to travel and other out-of-pocket expenses, and other similar third- party costs such as the cost of materials and certain subcontracts, are included in revenues, and an equivalent amount of reimbursable expenses are included in operating expenses. Any service fee associated with reimbursable expenses is included in revenues before reimbursements. The Company reports revenues net of subcontractor fees for certain subcontracts where the Company has determined that it is acting as an agent because its performance obligation is to arrange for the provision of goods or services by another party. The total amount of subcontractor fees not included in revenues because the Company was acting as an agent were $4,683,000 and $3,178,000 during the second quarter of 2026 and 2025, respectively, and $11,458,000 and $6,682,000 during the first six months of 2026 and 2025, respectively.

Note 3: Fair Value Measurements

The Company measures certain financial assets and liabilities at fair value on a recurring basis, including money market securities, trading fixed income and equity securities held in its deferred compensation plan and the liability associated with its deferred compensation plan. There were no transfers between fair value measurement levels during the three and six months ended July 3, 2026 and July 4, 2025. Any transfers between fair value measurement levels would be recorded on the actual date of the event or change in circumstances that caused the transfer. The fair value of these financial assets and liabilities was determined using the following inputs at July 3, 2026:

Note 4: Net Income Per Share

Basic per share amounts are computed using the weighted-average number of shares of common stock outstanding during the period. Diluted per share amounts are calculated using the weighted-average number of shares of common stock outstanding during the period and, when dilutive, the weighted-average number of potential shares of common stock from the issuance of common stock to satisfy outstanding restricted stock units and the exercise of outstanding options to purchase common stock using the treasury stock method.

The following schedule reconciles the shares used to calculate basic and diluted net income per share:

|  | Three Months Ended |  |  | Six Months Ended |
(In thousands) |  | July 3, 2026 |  |  | July 4, 2025 |  |  | July 3, 2026 |  |  | July 4, 2025 |
Shares used in basic per share computation |  |  | 48,753 |  |  |  | 51,185 |  |  |  | 49,271 |  |  |  | 51,234 |
Effect of dilutive common stock options outstanding |  |  | 8 |  |  |  | 82 |  |  |  | 28 |  |  |  | 93 |
Effect of dilutive restricted stock units outstanding |  |  | 226 |  |  |  | 235 |  |  |  | 272 |  |  |  | 260 |
Shares used in diluted per share computation |  |  | 48,987 |  |  |  | 51,502 |  |  |  | 49,571 |  |  |  | 51,587 |

Common stock options to purchas e 296,933 shares and 175,833 shares were excluded from the diluted per share calculation for the three months ended July 3, 2026 and July 4, 2025, respectively, due to their anti-dilutive effect. Common stock options to purchase 296,933 shares and 135,833 shares were excluded from the diluted per share calculation for the six months ended July 3, 2026 and July 4, 2025, respectively, due to their anti-dilutive effect.

Note 5: Stock-Based Compensation

## Restricted Stock Units

Restricted stock unit grants are designed to attract and retain employees, and to better align employee interests with those of the Company’s stockholders. For a select group of employees, up to 40% of their annual bonus is settled with fully vested restricted stock unit awards. Under these fully vested restricted stock unit awards, the holder of each award has the right to receive one share of the Company’s common stock for each fully vested restricted stock unit four years from the date of grant. Each individual who receives a fully vested restricted stock unit award is also granted a matching number of unvested restricted stock unit awards. Unvested restricted stock unit awards are also granted for select new hires and promotions. These unvested restricted stock unit awards generally cliff vest four years from the date of grant, at which time the holder of each award will have the right to receive one share of the Company’s common stock for each restricted stock unit award provided the holder of each award has met certain employment conditions. In the case of retirement at 59½ years or older, all unvested restricted stock unit awards will continue to vest, provided that the holder of each award does all consulting work through the Company and does not become an employee for a past or present client, beneficial party or competitor of the Company.

The value of these restricted stock unit awards is determined based on the market price of the Company’s common stock on the date of grant. The value of fully vested restricted stock unit awards issued is recorded as a reduction to accrued bonuses. The portion of bonus expense that the Company expects to settle with fully vested restricted stock unit awards is recorded as stock-based compensation during the period the bonus is earned. The Company recorded stock-based compensation expense associated with accrued bonus awards of $3,944,000 and $2,995,000 during the three months ended July 3, 2026 and July 4, 2025, respectively. For the six months ended July 3, 2026 and July 4, 2025, the Company recorded stock-based compensation expense associated with accrued bonus awards of $7,915,000 and $6,147,000, respectively. The value of the unvested restricted stock unit awards granted is recognized on a straight-line basis over the shorter of the four-year vesting period or the period between the grant date and the date the award recipient turns 59½. If the award recipient is 59½ years or older on the date of grant, the value of the entire award is expensed upon grant. The Company recorded stock-based compensation expense associated with the unvested restricted stock unit awards of $2,468,000 and $2,076,000 during the three months ended July 3, 2026 and July 4, 2025, respectively. The Company recorded stock-based compensation expense associated with the

- 13 -

unvested restricted stock unit awards of $6,882,000 and $6,316,000 during the six months ended July 3, 2026 and July 4, 2025, respectively.

## Stock Options

Stock options are granted for terms of ten years and generally vest 25% per year over a four-year period from the grant date. Unvested stock option awards will continue to vest in the case of retirement at 59½ years or older, provided that the holder of each award does all consulting work through the Company and does not become an employee for a past or present client, beneficial party or competitor of the Company. The value of the unvested stock option awards granted is recognized on a straight-line basis over the shorter of the four-year vesting period or the period between the grant date and the date the award recipient turns 59½. If the award recipient is 59½ years or older on the date of grant, the value of the entire award is expensed upon grant. The Company recorded stock-based compensation expense associated with stock option grants of $268,000 and $175,000 during the three months ended July 3, 2026 and July 4, 2025, respectively. The Company recorded stock-based compensation expense associated with stock option grants of $941,000 and $963,000 during the six months ended July 3, 2026 and July 4, 2025, respectively.

The Company uses the Black-Scholes option-pricing model to determine the fair value of options granted. The determination of the fair value of stock option awards on the date of grant using an option-pricing model is affected by the Company’s stock price as well as assumptions regarding a number of complex and subjective variables. These variables include expected stock price volatility over the term of the award, actual and projected employee stock option exercise behaviors, the risk-free interest rate and expected dividends.

The Company used historical exercise, forfeiture, and post-vesting expiration data to estimate the expected term of options granted. The historical volatility of the Company’s common stock over a period of time equal to the expected term of the options granted was used to estimate expected volatility. The risk-free interest rate used in the option-pricing model was based on United States Treasury zero-coupon issues with remaining terms similar to the expected term of the options. The dividend yield assumption considers the expectation of continued declaration of dividends, offset by option holders’ dividend equivalent rights.

The Company accounts for forfeitures of stock-based awards when they occur. All stock-based payment awards are recognized on a straight-line basis over the requisite service periods of the awards.

Note 6: Deferred Compensation Plans

The Company maintains nonqualified deferred compensation plans for the benefit of a select group of highly compensated employees. Under these plans, participants may elect to defer up to 100% of their compensation. Company assets that are earmarked to pay benefits under the plans are held in a rabbi trust and are subject to the claims of the Company’s creditors. As of July 3, 2026 and January 2, 2026, the invested amounts under the plans totaled $142,098,000 and $139,515,000, respectively, and are recorded in prepaid expenses and other current assets and deferred compensation plan assets on the Company’s unaudited condensed consolidated balance sheet. These assets are classified as trading securities and are recorded at fair value with changes recorded as adjustments to miscellaneous income, net.

As of July 3, 2026 and January 2, 2026, vested amounts due under the plans totaled $146,447,000 and $144,706,000, respectively, and are recorded within accrued payroll and employee benefits and deferred compensation plan liabilities on the Company’s unaudited condensed consolidated balance sheet. Changes in the liability are recorded as adjustments to compensation expense. During the three months ended July 3, 2026, the Company recognized additional compensation expense of $11,783,000 as a result of changes in the market value of the trust assets with the same amount being recorded as a gain in miscellaneous income, net. During the three months ended July 4, 2025, the Company recognized additional compensation expense of $16,963,000 as a result of changes in the market value of the trust assets with the same amount being recorded as a gain in miscellaneous income, net. During the six months ended July 3, 2026, the Company recognized additional compensation expense o f $10,645,000 as a result of changes in the market value of the trust assets with the same amount being recorded as a gain in miscellaneous income, net. During the six months ended July 4, 2025, the Company recognized additional compensation expense of $7,627,000 as a result of changes in the market value of the trust assets with the same amount being recorded as a gain in miscellaneous income, net.

The Company maintains allowances for estimated losses over the remaining contractual life of its receivables resulting from the inability of customers to meet their financial obligations or for disputes that affect the Company’s ability to fully collect amounts due. In circumstances where the Company is aware of a specific customer’s inability to meet its financial obligations or aware of a dispute with a specific customer, a specific allowance is recorded to reduce the net recognized receivable to the amount the Company reasonably believes will be collected. For all other customers the Company recognizes allowances for doubtful accounts based upon historical write-offs, customer concentration, customer creditworthiness, current economic conditions, aging of amounts due and future expectations.

A reconciliation of the beginning and ending amount of the allowance for contract losses and doubtful accounts is as follows:

# Note 10: Leases

The Company determines if an arrangement is a lease at the inception of the arrangement. Operating leases are included in operating lease right-of-use (“ROU”) assets, current operating lease liabilities, and long-term operating lease liabilities in the Company’s condensed consolidated balance sheet. The Company does not have any finance leases as of July 3, 2026.

ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate, based on the information available at commencement date, in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The amortization of operating lease ROU assets and the change in operating lease liabilities is disclosed as a single line item in the condensed consolidated statements of cash flows.

The Company leases office, laboratory, and storage space in 13 states and the District of Columbia, as well as in China, Germany, Hong Kong, Switzerland, and the United Kingdom. Leases for these office, laboratory, and storage facilities have terms generally ranging between one and ten years. Some of these leases include options to extend or terminate the lease, none of which are currently included in the lease term as the Company has determined that exercise of these options is not reasonably certain.

The Company has a Test and Engineering Center on 147 acres of land in Phoenix, Arizona. The Company leases this land from the State of Arizona under an agreement that expires in January of 2043 and includes an option to renew for one fifteen-year period.

The Company’s equipment leases are included in the ROU asset and liability balances, but are not material.

The Company leases excess space in its Silicon Valley and Natick facilities. Rental income of $397,000 and $285,000 was included in other income for the three months ended July 3, 2026 and July 4, 2025, respectively. Rental income of $729,000 and $476,000 was included in other income for the six months ended July 4, 2025 and July 4, 2025, respectively.

Engineering and Other Scientific |  | $ | 148,829 |  |  | $ | 120,980 |  |  |  | 23.0 | %
Percentage of total revenues |  |  | 86.7 | % |  |  | 85.2 | % |  |  |

Total revenues |  | $ | 171,612 |  |  | $ | 141,962 |  |  |  | 20.9 | %

The increase in revenues for our Engineering and Other Scientific segment was due to an increase in billable hours, increase in billing rates and an increase in revenues from reimbursements associated with user research projects. Growth during the quarter was driven by user research studies in consumer electronics and risk management in the utilities industry, along with reactive engagements across the consumer products, chemicals, and transportation industries. During the second quarter of 2026, billable hours for this segment increased by 10% to 320,000 as compared to 291,000 during the same period last year. Utilization for this segment increased to 76% during the second quarter of 2026 as compared to 74% during the same period last year. Average technical full-time equivalent employees in this segment increased 7% to 810 during the second quarter of 2026 as compared to 756 for the same period last year.

The increase in revenues for our Environmental and Health segment was due to an increase in billable hours and an increase in billing rates. Growth in this segment was driven by engagements evaluating the impacts of chemicals on human health and the environment. During the second quarter of 2026, billable hours for this segment increased by 3% to 70,000 as compared to 68,000 during the same period last year. Utilization for this segment increased to 66% during the second quarter of 2026 as compared to 65% during the same period last year. Average technical full-time equivalent employees in this segment were flat at 202 during the second quarter of 2026 and 2025.

Compensation and Related Expenses

|  | Three Months Ended |  |  |  |

Compensation and related expenses |  | $ | 100,571 |  |  | $ | 97,474 |  |  |  | 3.2 | %
Percentage of total revenues |  |  | 58.6 | % |  |  | 68.7 | % |  |  |

- 21 -

The increase in compensation and related expense during the second quarter of 2026 was due to an increase in payroll expense and an increase in bonus expense partially offset by a change in the value of assets associated with our deferred compensation plan. During the second quarter of 2026 payroll expense increased by $4,849,000 due to the impact of our annual salary increase and an increase in technical full-time equivalent employees. During the second quarter of 2026, bonus expense increased by $2,990,000 due to a corresponding increase in our bonus pool which is 33% of income before income taxes, interest income, bonus expense, and stock-based compensation. During the second quarter of 2026, deferred compensation expense decreased by $5,180,000 with a corresponding decrease to other income, net, as compared to the same period last year, due to the change in value of assets associated with our deferred compensation plans. During the second quarter of 2026, the value of plan assets increased by $11,783,000 as compared to an increase of $16,963,000 during the same period last year. We expect our compensation expense, excluding the change in value of deferred compensation plan assets, to increase as we selectively add new talent and adjust compensation to market conditions.

Other Operating Expenses

|  | Three Months Ended |  |  |  |
(In thousands, except percentages) |  | July 3, 2026 |  |  | July 4, 2025 |  |  | Percent Change |
Other operating expenses |  | $ | 12,865 |  |  | $ | 12,072 |  |  |  | 6.6 | %
Percentage of total revenues |  |  | 7.5 | % |  |  | 8.5 | % |  |  |

Other operating expenses include facilities-related costs, technical materials, computer-related expenses and depreciation and amortization of property, equipment and leasehold improvements. The increase in other operating expenses during the second quarter of 2026 was primarily due to an increase in computer-related expenses of $354,000 and an increase in occupancy expense of $270,000. The increase in computer-related expenses and occupancy expenses were due to continued investments in our corporate infrastructure. We expect other operating expenses to grow as we selectively add new talent and make investments in our corporate infrastructure.

Reimbursable Expenses

|  | Three Months Ended |  |  |  |
(In thousands, except percentages) |  | July 3, 2026 |  |  | July 4, 2025 |  |  | Percent Change |

Percentage of total revenues |  |  | 13.3 | % |  |  | 6.4 | % |  |  |

The amount of reimbursable expenses will vary from quarter to quarter depending on the nature of our projects. The increase in reimbursable expenses was due to an increase in reimbursable expenses associated with user research projects.

General and Administrative Expenses

|  | Three Months Ended |  |  |  |
(In thousands, except percentages) |  | July 3, 2026 |  |  | July 4, 2025 |  |  | Percent Change |
General and administrative expenses |  | $ | 7,402 |  |  | $ | 6,145 |  |  |  | 20.5 | %
Percentage of total revenues |  |  | 4.3 | % |  |  | 4.3 | % |  |  |

The increase in general and administrative expenses was primarily due to an increase in personnel expenses of $498,000, an increase in travel and meals of $246,000, and several other individually insignificant increases. The increase in personnel expenses was primarily due to an increase in relocation expenses. The increase in travel and meals was due to an increase in client and business development activities. We expect general and administrative expenses to increase as we selectively add new talent and expand our business development and staff development initiatives.

Total operating income |  | $ | 28,022 |  |  | $ | 17,177 |  |  |  | 63.1 | %

The increase in operating income for our Engineering and Other Scientific segment and our Environmental and Health segment during the second quarter of 2026 was due to an increase in utilization.

Certain operating expenses are excluded from our measure of segment operating income. These expenses include the costs associated with our human resources, legal, finance, information technology, corporate, and business development groups; the deferred compensation expense/benefit due to the change in value of assets associated with our deferred compensation plans; stock-based compensation associated with restricted stock unit and stock option awards; and the change in our allowance for contract losses and doubtful accounts.

The decrease in corporate operating expenses during the second quarter of 2026 as compared to the same period last year was primarily due to a decrease in deferred compensation expense. During the second quarter of 2026, deferred compensation expense decreased by $5,180,000, with a corresponding decrease to other income, net, as compared to the same period last year, due to the change in value of assets associated with our deferred compensation plans. During the second quarter of 2026, the value of plan assets increased by $11,783,000 as compared to an increase of $16,963,000 during the same period last year.

Percentage of total revenues |  |  | 7.4 | % |  |  | 13.8 | % |  |

Other income, net, consists primarily of changes in the value of assets associated with our deferred compensation plan, interest income earned on available cash, cash equivalents and short-term investments, and rental income from leasing space in our Silicon Valley and Natick facilities. The decrease in other income, net, was primarily due to a change in the value of assets associated with our deferred compensation plan and a decrease in interest income. During the second quarter of 2026, deferred compensation expense decreased by $5,180,000 with a corresponding decrease to other income, net, as compared to the same period last year, due to the change in value of assets associated with our deferred compensation plan. During the second quarter of 2026, the value of plan assets increased by $11,783,000 as compared to an increase of $16,963,000 during the same period last year. During the second quarter of 2026, interest income decreased by $1,628,000 due to lower average cash equivalent balances.

Total revenues |  | $ | 337,915 |  |  | $ | 287,469 |  |  |  | 17.5 | %

The increase in revenues for our Engineering and Other Scientific segment was due to an increase in billable hours, an increase in billing rates and an increase in revenues from reimbursements associated with user research projects. Growth during the first six months of 2026 was primarily driven by user research studies in consumer electronics and risk management in the utilities industry, along with reactive engagements across the consumer products, construction, and transportation industries. During the first six months of 2026, billable hours for this segment increased by 10% to 648,000 as compared to 591,000 during the same period last year. Utilization for this segment increased to 77% during the first six months of 2026 as compared to 75% during the same period last year. Average technical full-time equivalent employees in this segment increased 7% to 812 during the first six months of 2026 as compared to 759 for the same period last year.

The increase in revenues for our Environmental and Health segment was due to an increase in billing rates partially offset by a decrease in billable hours. During the first six months of 2026, billable hours for this segment decreased by 2% to 141,000 as compared to 144,000 during the same period last year. Utilization in this segment was flat at 68% during the first six months of 2026 and 2025. Average technical full-time equivalent employees in this segment decreased by 1% to 200 during the first six months of 2026 as compared to 203 during the same period last year.

Compensation and Related Expenses

|  | Six Months Ended |  |  |  |
(In thousands, except percentages) |  | July 3, 2026 |  |  | July 4, 2025 |  |  | Percent Change |
Compensation and related expenses |  | $ | 191,980 |  |  | $ | 173,377 |  |  |  | 10.7 | %
Percentage of total revenues |  |  | 56.8 | % |  |  | 60.3 | % |  |  |

The increase in compensation and related expenses during the first six months of 2026 was due to an increase in payroll, an increase in bonuses and the change in the value of assets associated with our deferred compensation plans. During the first six months of 2026, payroll expense increased by $9,008,000 due to an increase in technical full-time equivalent employees and the impact of annual salary increases. During the first six months of 2026, bonus expense increased by $5,928,000 due to a corresponding increase in our bonus pool which is 33% of income before income taxes, interest income, bonus expense, and stock-based compensation. During the first six months of 2026, deferred compensation expense increased by $3,018,000 with a corresponding increase to other income, net, as compared to the same period last year, due to the change in value of assets associated with our deferred compensation plan. This increase consisted of an increase in the value of plan assets of $10,645,000 during the first six months of 2026 as compared to an increase in the value of plan assets of $7,627,000 during the same period last year.

Other Operating Expenses

Percentage of total revenues |  |  | 7.6 | % |  |  | 8.4 | % |  |  |

Other operating expenses include facilities-related costs, technical materials, computer-related expenses and depreciation and amortization of property, equipment and leasehold improvements. The increase in other operating expenses during the first six months of 2026 was primarily due to an increase in occupancy expense of $658,000 and an increase in computer-related expenses of $608,000. The increase in occupancy expense and computer-related

- 24 -

expenses was due to continued investments in our corporate infrastructure. We expect other operating expenses to grow as we selectively add new talent and make investments in our corporate infrastructure.

Reimbursable Expenses

Percentage of total revenues |  |  | 11.0 | % |  |  | 6.0 | % |  |  |

The amount of reimbursable expenses will vary from quarter to quarter depending on the nature of our projects. The increase in reimbursable expenses was due to an increase in reimbursable expenses associated with user research projects.

General and Administrative Expenses

|  | Six Months Ended |  |  |  |
(In thousands, except percentages) |  | July 3, 2026 |  |  | July 4, 2025 |  |  | Percent Change |

Percentage of total revenues |  |  | 4.0 | % |  |  | 3.9 | % |  |  |

The increase in general and administrative expenses was primarily due to an increase in personnel expenses of $676,000 and an increase in travel and meals of $654,000. The increase in personnel expenses was due to an increase in relocation expenses. The increase in travel and meals was due to an increase in client and business development activities. We expect general and administrative expenses to increase as we expand our business development and staff development initiatives.

Operating Income

|  | Six Months Ended |  |  |  |
(In thousands, except percentages) |  | July 3, 2026 |  |  | July 4, 2025 |  |  | Percent Change |

Total operating income |  | $ | 69,401 |  |  | $ | 61,609 |  |  |  | 12.6 | %

The increase in operating income for our Engineering and Other Scientific segment during the first six months of 2026 as compared to the same period last year was due to an increase in utilization. The increase in operating income for our Environmental and Health segment during the first six months of 2026 was due to an increase in billing rates.

Certain operating expenses are excluded from our measure of segment operating income. These expenses include the costs associated with our human resources, legal, finance, information technology, and business development groups; the deferred compensation expense/benefit due to the change in value of assets associated with our deferred compensation plan; stock-based compensation associated with restricted stock unit and stock option awards; and the change in our allowance for contract losses and doubtful accounts.

The increase in corporate operating expenses during the first six months of 2026 as compared to the same period last year was primarily due to an increase in deferred compensation expense. During the first six months of 2026, deferred compensation expense increased by $3,018,000, with a corresponding increase to other income, net, as compared to the same period last year, due to the change in value of assets associated with our deferred compensation plans. During the first six months of 2026, the value of plan assets increased by $10,645,000 as compared to an increase of $7,627,000 during the same period last year.

Other Income, Net

|  | Six Months Ended |  |  |  |
(In thousands, except percentages) |  | July 3, 2026 |  |  | July 4, 2025 |  |  | Percent Change |
Other income (loss), net |  | $ | 13,704 |  |  | $ | 12,966 |  |  |  | 5.7 | %
Percentage of total revenues |  |  | 4.1 | % |  |  | 4.5 | % |  |  |

Other income, net, consists primarily of changes in the value of assets associated with our deferred compensation plan, interest income earned on available cash, cash equivalents and short-term investments, and rental income from leasing space in our Silicon Valley and Natick facilities. The increase in other income, net, was primarily due to a change in the value of assets associated with our deferred compensation plan partially offset by a decrease in interest income. During the first six months of 2026, deferred compensation expense increased by $3,018,000 with a corresponding increase to other income, net, as compared to the same period last year, due to the change in value of assets associated with our deferred compensation plan. During the first six months of 2026, the value of plan assets increased by $10,645,000 as compared to an increase of $7,627,000 during the same period last year. During the first six months of 2026, interest income decreased by $2,624,000 due to a decrease in interest rates and lower average cash equivalent balances.

Income Taxes

(In thousands, except percentages) |  | July 3, 2026 |  |  | July 4, 2025 |  |  | Percent Change |
Income taxes |  | $ | 24,141 |  |  | $ | 21,372 |  |  |  | 13.0 | %

Effective tax rate |  |  | 29.0 | % |  |  | 28.7 | % |  |  |

During the first six months of 2026, we realized a negative tax impact associated with stock-based awards of $843,000 as compared to a negative tax impact of $485,000 during the same period last year. The change in the tax impact associated with stock-based awards was due to the change in the difference of the value of our common stock between the grant date and the release date for the restricted stock units released during the first six months of 2026 as compared to the same period last year. Excluding the negative tax impact, our consolidated tax rate was 28.0% in the first six months of 2026 and 2025.

LIQUIDITY AND CAPITAL RESOURCES

We believe our existing balances of cash, cash equivalents, short-term investments and cash generated from operations will be sufficient to satisfy our working capital needs, capital expenditures, outstanding commitments, stock repurchases, dividends and other liquidity requirements over at least the next 12 months.

|  | Six Months Ended |
(In thousands) |  | July 3, 2026 |  |  | July 4, 2025 |
Net cash provided by operating activities |  | $ | 29,914 |  |  | $ | 43,496 |
Net cash used in investing activities |  |  | (4,228 | ) |  |  | (4,028 | )
Net cash used in financing activities |  |  | (180,833 | ) |  |  | (67,517 | )

We financed our business during the first six months of 2026 through available cash. As of July 3, 2026, our cash and cash equivalents were $66,629,000 as compared to $221,930,000 at January 2, 2026. The decrease in cash and cash equivalents was primarily due to an increase in repurchases of our common stock. During the first six months of 2026, we repurchased $146,138,000 of our common stock as compared to $32,680,000 during the same period last year.

Generally, our net cash provided by operating activities is used to fund our day-to-day operating activities. First quarter operating cash requirements are generally higher due to payment in the first quarter of annual bonuses accrued during the prior year. The largest source of operating cash flows is collections from our clients. Our primary

- 26 -

uses of cash from operating activities are for employee-related expenditures, leased facilities, taxes, and general operating expenses.

The increase in net cash used in investing activities during the first six months of 2026, as compared to the same period last year, was due to an increase in capital expenditures. The increase in capital expenditures was due to an increase in investment in our corporate infrastructure.

The increase in net cash used in financing activities during the first six months of 2026, as compared to the same period last year was primarily due to an increase in repurchases of our common stock. During the first six months of 2026, we repurchased $146,138,000 of our common stock as compared to $32,680,000 during the same period last year.

We lease office, laboratory, and storage space in 13 states and the District of Columbia, as well as in China, Germany, Hong Kong, Switzerland, and the United Kingdom under non-cancellable operating lease arrangements that expire at various dates through 2033. On June 19, 2024, we entered into an agreement with the State of Arizona to extend our land lease for 15 years beginning on January 17, 2028. We are currently obligated to make payments under the lease of $1,009,000 per year, which obligation will continue at that level until January 16, 2028. Beginning on January 17, 2028, our payments under the lease will increase to approximately $6,183,000 per year for the 15-year extension term with adjustments to the annual rent payment in 2033 and 2038 based on the consumer price index.

We expect to continue our investing activities, including capital expenditures. Furthermore, cash reserves may be used to repurchase common stock under our stock repurchase programs, pay dividends, procure facilities and equipment or strategically acquire professional service firms that are complementary to our business.

We maintain nonqualified deferred compensation plans for the benefit of a select group of highly compensated employees. Vested amounts due under the plans of $127,839,000 were recorded as a deferred compensation plan liability on our unaudited condensed consolidated balance sheet at July 3, 2026. Vested amounts due under the plans of $18,609,000 were recorded as an accrued payroll and employee benefits on our unaudited condensed consolidated balance sheet at July 3, 2026. Company assets that are designated to fund the benefits under the plans are held in a rabbi trust and are subject to the claims of our creditors. As of July 3, 2026, invested amounts under the plans of $122,823,000 were recorded as a non-current asset on our unaudited condensed consolidated balance sheet. As of July 3, 2026, invested amounts under the plans of $19,274,000 were recorded as other current assets on our unaudited condensed consolidated balance sheet.

As permitted under Delaware law, we have agreements whereby we indemnify our officers and directors for certain events or occurrences while the officer or director is, or was serving, at our request in such capacity. The indemnification period covers all pertinent events and occurrences during the officer’s or director’s lifetime. The maximum potential amount of future payments we could be required to make under these indemnification agreements is unlimited; however, we have director and officer insurance coverage that reduces our exposure and enables us to recover a portion of any future amounts paid. We believe the estimated fair value of these indemnification agreements in excess of applicable insurance coverage is minimal.

Non-GAAP Financial Measures

Regulation G, Conditions for Use of Non-Generally Accepted Accounting Principles ("Non-GAAP") Financial Measures, and other U.S. Securities and Exchange Commission (“SEC”) rules and regulations define and prescribe the conditions for use of Non-GAAP financial information. Generally, a Non-GAAP financial measure is a numerical measure of a company’s performance, financial position or cash flow that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. We closely monitor two financial measures, EBITDA and EBITDAS, which meet the definition of Non-GAAP financial measures. We define EBITDA as net income before net interest income, income taxes, depreciation and amortization. We define EBITDAS as EBITDA before stock-based compensation. The Company regards EBITDA and EBITDAS as useful measures of operating performance to complement operating income, net income and other GAAP financial performance measures. Additionally, management believes that EBITDA and EBITDAS provide meaningful comparisons of past, present and future operating results. These measures are used to evaluate our financial results, develop budgets and determine employee compensation. These measures, however, should be considered in addition to, and not as a substitute for or superior to, operating income, cash flows,

- 27 -

or other measures of financial performance prepared in accordance with GAAP. A reconciliation of the Non-GAAP measures to the nearest comparable GAAP measure is set forth below.

The following table is a reconciliation of EBITDA and EBITDAS to the most comparable GAAP measure, net income, for the three and six months ended July 3, 2026 and July 4, 2025:

EBITDAS |  | $ | 49,408 |  |  | $ | 42,237 |  |  | $ | 101,602 |  |  | $ | 87,955 |

The following table shows EBITDA (determined as shown in the reconciliation table below) as a percentage of revenues before reimbursements for the three and six months ended July 3, 2026 and July 4, 2025:

|  | Three Months Ended |  |  | Six Months Ended |

EBITDA |  | $ | 42,728 |  |  | $ | 36,991 |  |  | $ | 85,864 |  |  | $ | 74,529 |
EBITDA as a % of revenues before reimbursements |  |  | 28.7 | % |  |  | 27.8 | % |  |  | 28.6 | % |  |  | 27.6 | %

The increase in EBITDA as a percentage of revenues before reimbursements during the three and six months ended July 3, 2026 as compared to the same periods last year was primarily due to an increase in net revenues and an increase in utilization.

Item 3. Quantitative and Qualita tive Disclosures About Market Risk

We are exposed to interest rate risk associated with our balances of cash and cash equivalents. We manage our interest rate risk by maintaining an investment portfolio primarily consisting of debt instruments with high credit quality and relatively short average effective maturities in accordance with our investment policy. The maximum effective maturity of any issue in our portfolio is three years and the maximum average effective maturity of the portfolio cannot exceed 12 months. If interest rates were to instantaneously increase or decrease by 100 basis points, the change in the fair market value of our portfolio of cash equivalents would not have a material impact on our financial statements. We do not use derivative financial instruments in our portfolio. There have not been any material changes during the period covered by this Quarterly Report on Form 10-Q to our interest rate risk exposures, or how these exposures are managed. Notwithstanding our efforts to manage interest rate risk, there can be no assurances that we will be adequately protected against the risks associated with interest rate fluctuations.

We have foreign currency risk related to our revenues and expenses denominated in currencies other than the U.S. dollar, primarily the British Pound, the Euro, the Chinese Yuan, the Hong Kong Dollar, and the Singapore Dollar. Accordingly, changes in exchange rates may negatively affect the revenues and net income of our foreign subsidiaries as expressed in U.S. dollars.

At July 3, 2026, we had net assets of approximately $12.5 million with a functional currency of the British Pound, net assets of approximately $2.8 million with a functional currency of the Chinese Yuan, net assets of approximately $2.8 million with a functional currency of the Hong Kong Dollar, and net assets of approximately $1.8 million with a functional currency of the Singapore Dollar associated with our operations in the United Kingdom, China, Hong Kong, and Singapore, respectively.

We also have foreign currency risk related to foreign currency transactions and monetary assets and liabilities denominated in currencies that are not the functional currency. We have experienced and will continue to experience fluctuations in our net income as a result of gains (losses) on these foreign currency transactions and the remeasurement of monetary assets and liabilities. At July 3, 2026, we had net assets denominated in the non-functional currency of approximately $2.7 million.

We do not use foreign exchange contracts to hedge any foreign currency exposures. To date, the impacts of foreign currency exchange rate changes on our consolidated revenues and consolidated net income have not been significant. However, our continued international growth increases our exposure to exchange rate fluctuations and as a result such fluctuations could have a significant impact on our future results of operations.

Item 4. Controls and Procedures

(a)
Evaluation of Disclosure Controls and Procedures

As required by Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended, an evaluation was performed under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) of the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this quarterly report. Based on that evaluation, the Company’s management, including the Chief Executive Officer and the Chief Financial Officer, concluded that, as of July 3, 2026, the Company’s disclosure controls and procedures were effective.

We review and evaluate the design and effectiveness of our disclosure controls and procedures on an ongoing basis, to improve our controls and procedures over time and to correct any deficiencies that we may discover in the future. Our goal is to ensure that our senior management has timely access to all material financial and non-financial information concerning our business. While we believe the present design of our disclosure controls and procedures is effective to achieve our goal, future events affecting our business may cause us to significantly modify our disclosure controls and procedures.

(b)
Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the three-month period ended July 3, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
