Willdan Group, Inc. (WLDN) | The Buildout — AI Infrastructure

The Verdict

Willdan Group is a services company. It provides engineering, program management, and consulting to utilities, government agencies, and commercial clients — the work of planning, designing, and delivering energy and infrastructure projects. Its most direct link to the AI build-out runs through the electric grid: data centers need substations, interconnects, and power blocks, and Willdan's engineering teams design and manage them. It also runs utility energy-efficiency programs and advises on where and how large electric loads get served. It builds no hardware; its capacity is people and leased offices.

Earnings Beat

Q2 FY2026 (quarter ended July 3, 2026) contract revenue was $231.0M, up 33.2%, with net revenue of $117.2M, up 23.5%. Adjusted EBITDA rose 50.6% to $33.0M — a record 28.2% of net revenue and the highest quarterly margin in company history. Net income was $24.3M, up 57.7%, and GAAP diluted EPS was $1.58. Gross margin fell 150 basis points as mix shifted toward performance engineering and commercial work.

Management tone: Management's tone shifted toward confidence with explicit tempering. Across the two calls in the record, they raised full-year guidance twice and raised the long-term adjusted EBITDA margin target to the high 20s, while warning that the record 28.2% margin would not hold. In Q&A they answered directly on the tax change, Burton cross-selling, and geographic expansion, and declined only to forecast LADWP's Q3 contribution, calling it too early to tell.

Management Guidance

Management guides FY2026 net revenue to $415–430M, adjusted EBITDA to $103–107M, and adjusted diluted EPS to $5.00–$5.15, assuming roughly 15.9M diluted shares and a 0% effective tax rate for the year. The company expects the FY2026 adjusted EBITDA margin to reach about 25%, up from 21.8% in 2025, and reaffirmed a long-term target in the high 20s. For the second half it flagged a P&L tax rate of 15%–20% and said Q3 and Q4 should look similar to Q2 but "may not be quite as strong as what Q2 was."

Trajectory

Contract revenue stepped up sharply in Q2 FY2026, to $231.0M from $155.1M in Q1, lifting trailing-twelve-month revenue to $741.8M, about 18% higher year over year. The jump reflects the Burton acquisition, which closed May 4, plus the organic commercial ramp; organic net revenue grew 18%. On the company's own measure, adjusted EBITDA margin reached a record 28.2% of net revenue. On the code-computed basis — operating income plus D&A against contract revenue — EBITDA margin is compressing, and gross margin is roughly flat to lower (Q2's 37.9% versus 39.4% a year earlier). The two views differ because contract revenue is growing faster than net revenue as equipment and subcontractor cost passes through.

The Model

The model projects FY+1 revenue of $820M and EBITDA of $86M, a 10.5% margin, and FY+2 revenue of $980M and EBITDA of $114M, an 11.63% margin. The near-term anchor is the FY2026 guidance range and work already won — the LADWP expansion, the SCE extension, and APG's data-center power projects. The FY+2 step depends on whether APG's 2027–2028 power-block pipeline converts and whether the acquisition pipeline keeps adding engineering capacity.

Projections are the median of 5 independent model runs. The model’s revenue sits 137.4% above analyst consensus.

What Could Go Right — and Wrong

Looking Ahead

The next twelve months turn on whether the named award set converts on schedule. Management has pre-set the shape: Q3 and Q4 similar to Q2 but possibly not as strong, a second-half P&L tax rate of 15%–20%, and the revolver repaid by year-end. The LADWP expansion ramps through Q3 into early 2027, APG's data-center work runs on projects already won, and the acquisition pipeline in electrical engineering remains active.

The Company

Willdan Group provides professional, technical, and consulting services to utilities, private industry, and public agencies. Through engineering, program management, policy advisory, and software and data analytics, it plans, designs, and delivers work that improves efficiency, resiliency, and sustainability in energy and infrastructure. It reports two segments: Energy, which was $128.0M of $155.1M Q1 FY2026 contract revenue (82.5%), and Engineering and Consulting. The most direct tie to AI is electricity — data centers need substations, interconnects, and power blocks, and Willdan's APG team designs and builds them.

Willdan is a services business, not a manufacturer. It discloses no owned manufacturing or plant capacity; its capacity is people and leased offices, plus engineering teams bought through acquisition. Its headquarters is in Anaheim, California, and it has 48 other leased locations. As of the 2026-05-08 call it had active projects in all 50 states and permanent offices in 26 of them, with new hubs opened in Florida, Georgia, North Carolina, Kentucky, and Texas over the prior 18 months. It is broadening beyond a California and New York base, pulled largely by where data centers are being built.

Business Segments

Competitive Landscape

Management describes its edge as relationship- and specialization-based rather than scale-based. It calls itself a "buyer of choice" in M&A because some firms will not sell to private equity, and it points to its ability to displace long-held incumbents — the $27M New York Accelerator contract had been held for many years by one of its strongest competitors. The competitive set includes far larger engineering and consulting firms that also serve utilities, government agencies, and data centers.

Supply Chain

Willdan sits in the service layer of the energy and infrastructure chain — a technical-services intermediary that designs and manages projects for utilities, agencies, and commercial clients, not a manufacturer or a utility. No neighbor transcript in the source names Willdan.
