Memo

WILLDAN GROUP, INC. (WLDN). Latest full fiscal year: 2026; data up to 2026-07-03.

Figures computed from the financial statements: revenue 681.6 m USD in 2026; net margin 8.8%; ROE 21.2%; net debt/EBITDA 0.4x.

The estimated value range is 82.21–115.39 USD per share (median of 2 methods, agreement: low); assumptions are illustrative. Against the central value of 99.93 USD, the price of 74.20 USD leaves a potential of 34.7% (value / price − 1) and a margin of safety of 25.7% (1 − price / value). The range is the median of the methods' low, central and high values, not a probability interval.

olivLaw score 70/100, methodological classification: neutral profile (score, margin of safety and method agreement together; not a judgement of the right price). Groups assessed only in part: returns. Not investment advice.

Text generated deterministically from the figures shown; no language model. Not investment advice.

What supports the thesis

  • Net margin: 8.8%
  • FCF conversion: 95.4%
  • Revenue CAGR 3Y: 10.1%
  • EPS CAGR 3Y: 63.4%
  • Net debt / EBITDA: 0.4x
  • P/E (TTM): 17.4x
  • The price is below the estimated value range

What contradicts it

  • EV/EBITDA: 15.8x
  • The valuation methods diverge

Not assessed (insufficient data or a ratio without meaning): Interest coverage, Shareholder yield (distributions), Payout ratio (FCF).

In brief

Willdan Group provides technical, engineering and consulting services to utilities, public agencies and private clients, focused on energy efficiency, emissions reduction and infrastructure. The company is relevant now because electricity demand from AI data centers and electrification supports its Energy segment, which makes up most of revenue, and contract revenue rose 33.2% in the second quarter of fiscal 2026 23.

SWOT

Strengths

  • The company has long relationships with public agencies and utilities, and many contracts are with clients served for years 1.
  • The offering spans energy services and engineering and consulting, allowing synergies between segments 12.
  • Growth in revenue and gross margin in fiscal 2025 shows an ability to benefit from the contract mix 1.

Weaknesses

  • A significant share of revenue is concentrated in a few large customers, which increases exposure to losing a contract 1.
  • Many contracts are fixed-price, and cost overruns can reduce profit or create losses on individual projects 1.
  • The company relies heavily on subcontractors, which can affect quality and timing if they fail to meet obligations 1.

Opportunities

  • Demand for power from AI data centers and electrification could expand the energy services market 1.
  • Recent acquisitions such as Burton and Compass could add revenue and capabilities if integration succeeds 23.
  • Emissions reduction goals and the modernization of aging infrastructure could create new projects for agencies 1.

Threats

  • An economic slowdown or tighter government budgets could delay or cancel projects 1.
  • Changes in state regulatory commission rules could reduce the appeal of utility contracts 1.
  • Higher interest rates and inflation could raise costs and pressure clients to seek lower prices 1.

Risks

  • Customer concentrationhigh

    Two contracts represent a significant part of revenue in the Energy segment, and losing them could affect results 1.

  • Cost overrun riskhigh

    Fixed-price contracts can generate losses if cost estimates prove wrong or projects are delayed 1.

  • Dependence on regulationmedium

    Energy revenue depends on state commission policies, which can change demand and contract terms 1.

  • Cyclical public demandmedium

    Government budgets and private investment can decline during economic slowdowns 1.

  • Acquisition integrationlow

    Recent acquisitions might not deliver expected benefits if integration of staff and systems proves difficult 3.

Investment thesis

What would need to be true (bull case)

  • If demand linked to AI data centers and electrification continues, revenue growth in the Energy segment could support the higher margins seen in 2026 23.
  • Management's raised net revenue target signals confidence in the contract portfolio and recent acquisitions 3.
  • Long relationships with public and utility clients could provide revenue continuity even during uncertain periods 1.

What would break the thesis

  • Concentration of revenue in a few large clients could make results sensitive to their budget or investment decisions 1.
  • Fixed-price contracts expose the company to cost overruns that could reduce profitability in certain quarters 1.
  • Rapid growth through acquisitions could create integration difficulties and pressure on overhead costs 2.

What to watch

The business

Willdan Group, Inc. is a provider of professional, technical and consulting services to utilities, private industry and public agencies at all levels of government 1. The company was founded in 1964 and describes itself as a professional services firm focused on growth and value creation for clients, employees and shareholders 12. It operates through a network of offices in 22 states, the District of Columbia, the Canadian province of Alberta and Puerto Rico 1.

The business model combines organic growth with strategic acquisitions that expand the services offered to new and existing clients 1. Clients include most of the largest investor-owned electric utilities and over half of the largest municipal utilities in the United States, as well as schools, universities, cities and counties 1. Individual projects typically last between two and twenty-four months, while utility contracts can run up to five years 1.

In 2026 the company added businesses through acquisitions including Burton Energy Group, LLC, acquired in May 2026, and Compass Municipal Advisors, LLC, acquired in January 2026 2. Management raised its fiscal 2026 net revenue target, which points to continued growth if demand for energy services holds 3.

Segments

Energy

The Energy segment accounted for 85% of contract revenue in fiscal 2025 1. It offers energy planning, efficiency programs, grid projects, AI data center power solutions, construction management and measurement and verification services for utilities, governments and commercial clients 12.

Engineering and Consulting

The Engineering and Consulting segment covers the remainder of revenue and focuses on civil infrastructure, building and safety services, city engineering and financial consulting for local governments 12. The company often acts as a municipality's engineering department 2.

Market context

The company operates in the energy services market and the engineering and consulting market, mainly for public agencies, utilities and commercial firms 1. According to the annual report, demand is supported by rapid growth in AI, which raises power demand from data centers, as well as electrification and decarbonization goals 1.

The market is shaped by state energy regulatory commissions, which set goals and terms for utility programs, and changes in those rules can alter demand and contract economics 1. Government budgets and private spending remain key factors, especially during economic slowdowns 1.

Trends

  • Demand from AI data centerstailwind

    Rising grid load from AI data centers is cited by the company as a driver of expansion in the energy services market 1. If this demand materializes, it could support revenue in the Energy segment.

  • Electrification and energy transitiontailwind

    Electric vehicles, battery storage and wind and solar integration change how energy is generated and consumed, creating need for planning and grid modernization services 1. These shifts are favorable if utilities keep investing.

  • Sensitivity of public budgetsheadwind

    Demand for services is cyclical and vulnerable to economic downturns or worsening government fiscal conditions, which can delay or cancel projects 1. These conditions could weigh on the public engineering business.

  • Changes in energy regulationmixed

    Changes in regulatory commission mandates can alter the terms and profitability of utility contracts, either favorably or unfavorably 1. The effect depends on the direction of state policy.

Competitive position

The company says it operates in a highly competitive energy services market and must win new contracts and renew existing ones through bidding processes 3. Public engineering contracts are awarded mainly on professional qualifications rather than fees, which favors firms with long agency relationships 1.

Competition includes energy services and engineering firms offering the same types of contracts to utilities and local governments 13. The sources consulted do not name direct competitors, so market shares and performance comparisons cannot be given.

  • Energy services and energy efficiency firms

    The sources do not name specific competitors; the company describes them only as part of a highly competitive market.

  • Engineering and consulting firms serving public agencies

    Competition comes from firms offering similar municipal engineering and financial consulting services, according to the annual report.

  • Construction and program management firms

    Companies offering construction management and installation of efficiency measures can compete for the same utility projects.

  • Utility program consulting firms

    Firms providing utility program consulting and energy planning appear as alternatives for large clients.
