Exponent Reports Third Quarter of Fiscal Year 2025 Financial Results

MENLO PARK, Calif., Oct. 30, 2025 (GLOBE NEWSWIRE) -- Exponent, Inc. (Nasdaq: EXPO) today reported financial results for the third quarter of fiscal year 2025 ended October 3, 2025.

“Exponent delivered a strong third quarter, achieving double digit net revenue growth that reflects the strength of our diversified portfolio and our ability to deliver value across industries,” stated Dr. Catherine Corrigan, President and Chief Executive Officer. “Increasing demand for dispute-related work drove robust growth in reactive engagements across the energy, transportation, life sciences and construction sectors. Proactive engagements were led by risk management and asset integrity projects in the utilities sector and regulatory consulting in the chemical sector. While these were offset by lower activity in consumer electronics, we are encouraged by improving demand trends in this space as we enter the fourth quarter.

“As artificial intelligence is increasingly integrated into safety-critical systems, Exponent is helping clients navigate risk and innovate responsibly. From automotive and utilities to life sciences and consumer products, our teams are at the forefront of addressing the increasingly complex technical and human-machine challenges that accompany rapid technological change. As innovation accelerates, so does our differentiation, driven by a one-of-a-kind, integrated ecosystem of experts that is uniquely positioned to tackle complex challenges while capturing new opportunities for growth,” Dr. Corrigan continued.

Third Quarter Financial Results

Total revenues and revenues before reimbursements for the third quarter of 2025 increased 8% to $147.1 million and 10% to $137.1 million, respectively, as compared to $136.3 million and $125.1 million in the third quarter of 2024.

Net income increased to $28.0 million, or $0.55 per diluted share, in the third quarter of 2025, as compared to $26.0 million, or $0.50 per diluted share, in the same period of 2024.

Inclusive of the tax benefit, Exponent’s consolidated tax rate was 27.4% in the third quarter, as compared to 27.5% for the same period in 2024.

EBITDA¹ increased to $38.8 million, or 28.3% of revenues before reimbursements, in the third quarter of 2025, as compared to $35.8 million, or 28.6% of revenues before reimbursements in the third quarter of 2024.

Net income decreased to $81.2 million, or $1.58 per diluted share, through the first three quarters of 2025, as compared to $85.4 million, or $1.66 per diluted share, in the same period of 2024. During the first three quarters of 2025, we realized a negative tax impact associated with share-based awards of $0.4 million, as compared to a positive benefit of $2.2 million during the same period one year ago.

Through the first three quarters of 2025, Exponent paid $46.7 million in dividends, repurchased $72.7 million of common stock, and closed the period with $207.4 million in cash and cash equivalents.  

In a separate press release today, Exponent announced its quarterly cash dividend of $0.30 to be paid on December 19, 2025 and reiterated its intent to continue to pay quarterly dividends.

Business Overview

Exponent’s engineering and other scientific segment represented 84% of the Company’s revenues before reimbursements in the third quarter and through the first three quarters of 2025. Revenues before reimbursements in this segment increased 10% in the third quarter and 3% through the first three quarters of 2025, as compared to the prior year period. Growth during the quarter was driven by demand for Exponent's risk management and asset integrity management services in the utilities industry and dispute-related services in the energy, automotive and medical device sectors.

Exponent’s environmental and health segment represented 16% of the Company’s revenues before reimbursements in the third quarter and through the first three quarters of 2024. Revenues before reimbursements in this segment increased 9% in the third quarter and 2% through the first three quarters of 2025, as compared to the prior year period. Growth in this segment was driven by increased regulatory consulting engagements in the chemicals industry.

Business Outlook

“We delivered strong financial performance during the third quarter of 2025 and are encouraged by the influx of new engagements and high-quality talent coming into the business. We are strategically increasing headcount to support growth while generating solid utilization and strong rate realization, reflecting our differentiation in the marketplace,” commented Richard Schlenker, Executive Vice President and Chief Financial Officer. “As we close out 2025, we are maintaining our revenue guidance and raising our margin guidance for the full year. Looking ahead, our conviction in Exponent’s long-term growth trajectory remains steadfast, as reflected in the Board of Directors’ recent approval to increase our share repurchase authorization.”

Exponent is returning to a 13-week fiscal fourth quarter in 2025, which poses a headwind for comparisons since Q4 of fiscal 2024 benefited from a 14th week. For the fourth quarter of fiscal 2025 as compared to the fourth quarter of fiscal 2024, Exponent anticipates:

• Revenues before reimbursements to grow in the low to mid-single digits (high single-digit to low double-digit growth when adjusted for the extra week during Q4 of 2024); and,
• EBITDA¹ to be 26.0% to 27.0% of revenues before reimbursements.

Exponent is returning to a 52-week fiscal year in 2025, which poses a headwind for full-year comparisons since fiscal 2024 benefited from a 53rd week. For the full fiscal year 2025 as compared to fiscal year 2024, Exponent anticipates:

• Revenues before reimbursements to grow in the low single digits; and,
• EBITDA¹ to be 27.4% to 27.65% of revenues before reimbursements.

“Rapid innovation is accelerating industry transformation as companies strive to compete, while expectations for safety, health, and the environment reach new heights and the consequences of failure intensify. Exponent is uniquely positioned to capitalize on these enduring and powerful trends, driving long-term growth and value creation for our stakeholders,” concluded Dr. Corrigan.

Use of non-GAAP Financial Measures ¹

EBITDA is a non-GAAP financial measure defined by the Company as net income before income taxes, interest income, depreciation, and amortization. EBITDAS is a non-GAAP financial measure defined by the Company as EBITDA before stock-based compensation. The Company regards EBITDA and EBITDAS as useful measures of operating performance and cash flow 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. 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. These measures, however, should be considered in addition to, and not as a substitute or superior to, operating income, cash flows, or other measures of financial performance prepared in accordance with GAAP.

Exponent has provided its outlook regarding EBITDA as a percentage of revenues before reimbursements. The Company has not reconciled this non-GAAP financial measure to the corresponding GAAP financial measure because guidance for the various reconciling items is not provided and the Company is unable to estimate with reasonable certainty the effect of these items without unreasonable effort. For example, the Company is unable to estimate with reasonable certainty the impact of equity awards on Exponent’s taxes without unreasonable effort. These items are uncertain, depend on various factors, and may have a material effect on Exponent’s results computed in accordance with GAAP. A reconciliation between the historical GAAP and non-GAAP financial measures presented in this release is provided in the financial tables at the end of this release.
