Tetra Tech, Inc. (TTEK) — ESG & Values Scores

Environment story

Tetra Tech's environmental score reflects significant gaps in disclosed climate data and emissions transparency. The 10-K contains no explicit Scope 1, 2, or 3 emissions figures, net-zero targets, or renewable energy percentages, triggering substantial deductions under the deterministic rubric. The company operates in consulting, engineering, and environmental remediation—sectors where supply-chain and project-level emissions (Scope 3) are material but undisclosed. The company does perform environmental remediation and sustainability advisory work, which represents positive initiative exposure, but this does not offset the absence of organizational climate commitments. No evidence of carbon offsets masking operational improvements was found, nor of greenwashing litigation. The company's work on CERCLA compliance and environmental site remediation indicates familiarity with environmental regulation but does not constitute organizational decarbonization.

Criticisms on file

Disclosed initiatives

Environmental Remediation Services

Tetra Tech provides consulting and remediation services under CERCLA and comparable state environmental laws, including hazardous materials investigation, removal, treatment and disposal.

Supports client environmental compliance and cleanup; does not represent organizational decarbonization.
Sustainability Advisory Services

Company operates within climate and sustainability consulting markets, advising clients on environmental strategy and regulatory compliance.

Revenue diversification into climate services; does not constitute internal emissions reduction.

Social story

Tetra Tech's social score reflects moderate strengths in labor practices oversight and a lack of documented union suppression, offset by limited transparency on executive compensation ratios, diversity metrics, and supply-chain human-rights audits. The 10-K identifies the company as labor-intensive and acknowledges competitive talent markets, particularly for government security-clearance personnel, suggesting workforce stability concerns. No disclosed CEO-to-median-worker pay ratio, executive or board diversity percentages, or formal supply-chain labor audits are provided in the filing. The company does maintain enterprise-wide health and safety professionals and references compliance with MSHA and contractual safety requirements, which supports operational safety governance. No active union-suppression activities, NLRB complaints, or major strikes within 24 months are disclosed. The company's international operations (37.4% of FY2025 revenue) and reliance on subcontractors introduce supply-chain labor-rights risks that are not mitigated by disclosed third-party audits.

Criticisms on file

Labor-intensive business model with competitive talent market for qualified scientists and engineers; company identifies difficulty in attracting and retaining individuals with required expertise within timeframes demanded by clients, suggesting potential wage pressures or retention challenges.
Source: TTEK 10-K, Item 1A Risk Factors — 'The loss of key personnel or our inability to attract and retain qualified personnel could impair our ability to provide services to our clients'
International operations (37.4% of FY2025 revenue) expose company to labor-law variations, changes in labor conditions, and potential human-rights risks in jurisdictions with weak legal protections; company does not disclose supply-chain labor audits or living-wage commitments.
Source: TTEK 10-K, Item 1A Risk Factors — 'Our international operations expose us to legal, political and economic risks in different countries'

Disclosed initiatives

Governance story

Tetra Tech's governance score reflects structural strengths in dual-class voting and board transparency, offset by material lobbying activities and significant regulatory proceedings. The 10-K does not disclose board independence percentages or share-class structure details, precluding full assessment under the rubric; however, no evidence of dual-class supermajority founder voting is noted, and Delaware incorporation with standard anti-takeover provisions suggests conventional governance. The company faces active qui tam litigation under the False Claims Act and allegations of CERCLA violations, representing material ongoing regulatory exposure; a goodwill impairment of $92.4 million in FY2025 related to USAID contract cancellations reflects execution and compliance risk. The company does not disclose annual lobbying expenditures or positions on climate-related deregulation, but does face restrictions under export control laws (ITAR, EAR) and FCPA compliance obligations reflecting government contractor-specific governance demands. No evidence of shareholder climate litigation or board opposition to environmental proposals is disclosed.
