Breaking Down Willdan Group, Inc. (WLDN) Financial Health: Key Insights for Investors

You're looking at Willdan Group, Inc. (WLDN) because the numbers are defintely moving, and you want to know if the underlying business is as strong as the stock chart suggests. The short answer is that the company is riding a powerful wave of electrification and data center demand, which is showing up directly in their latest guidance. Following a stellar Q3 2025 where Net Revenue hit $95.0 million-a 25.5% jump year-over-year-management substantially raised its full-year outlook. They now project 2025 Net Revenue to land between $360 million and $365 million, with Adjusted Diluted Earnings Per Share (EPS) expected to be between $4.10 and $4.20, a significant increase from prior estimates. That's a massive growth story, but it's crucial to understand the engine: 20% organic growth in Q3, largely driven by the Energy segment's work on grid resilience and power optimization for those high-load data centers. We need to map out if this growth is sustainable, especially with the reliance on government and utility contracts, plus, what the expanded Adjusted EBITDA margin, now guided between $77 million and $78 million, truly means for long-term profitability versus a potential slowdown in capital expenditure (CapEx) spending next year.

Revenue Analysis

You need to know where Willdan Group, Inc. (WLDN)'s momentum is coming from, and the answer is simple: the grid. The company is on track for a strong 2025, driven by a surge in demand for energy efficiency and infrastructure work, especially from data centers.

Management raised its full-year 2025 net revenue guidance to a range of $360 million to $365 million, a clear sign of confidence following a powerful third quarter. This revised outlook is defintely a key metric to watch, and it's largely powered by a robust 20% organic growth rate in Q3 2025.

Breaking Down the Revenue Engine

Willdan Group, Inc.'s revenue streams are concentrated, which gives them focus but also adds a layer of customer concentration risk. The vast majority of their business is in the Energy segment, which accounts for roughly 85% of their overall revenue. This segment delivered $154.75 million in revenue during Q3 2025 alone.

The remaining revenue comes from their Engineering & Consulting segment, which contributed $27.26 million in Q3 2025. This split shows you where the core value proposition lies: helping utilities and government entities manage and optimize their power infrastructure. The company's Mission Statement, Vision, & Core Values of Willdan Group, Inc. (WLDN) directly reflect this focus on energy and infrastructure innovation.

Here's the quick math on recent growth:

• Q3 2025 Net Revenue: $95.0 million
• Year-over-Year Net Revenue Growth (Q3 2025): 25.5%
• Nine-Month YTD 2025 Net Revenue: $275.3 million

In terms of customers, the stability comes from utilities, state, and local governments. But the near-term opportunity is in the commercial space. The commercial customer segment is expected to contribute about 15% of fiscal 2025 revenue, and this work is heavily concentrated around the massive electricity usage of data centers.

Shifts and Opportunities in the Revenue Mix

The most significant change in the revenue profile is the accelerating demand tied to electrification and the AI-driven load growth from data centers. This is a clear, structural tailwind, not a one-off trend. For example, Willdan Group, Inc. recently secured a $97 million energy and infrastructure project in Alameda County. That's a concrete example of a large, complex contract win that moves the needle.

Also, don't forget the impact of strategic acquisitions. The recent additions, like Alternative Power Generation, Inc. (APG), contributed 6% of the Q3 2025 net revenue growth, adding both scale and specialized electrical engineering capabilities for substations. This is smart growth, buying expertise that directly addresses the data center and renewables boom.

To be fair, what this estimate hides is the high concentration risk; a large portion of their revenue still comes from a small number of key customers, so monitoring contract renewals is crucial. Still, the overall picture for 2025 revenue is one of strong execution in a high-demand market.

Profitability Metrics

Willdan Group, Inc. (WLDN) shows a clear and accelerating profitability trend in fiscal year 2025, largely driven by its core Energy segment. Your key takeaway is that the company's operational efficiency is improving, pushing margins above recent historical averages, but the net margin still lags behind the strong gross margin.

Looking at the trailing twelve months (TTM) ending in November 2025, Willdan generated a total revenue of approximately $651.93 million. This strong top-line performance translates into solid, improving margins. Here's the quick math on the TTM figures:

• Gross Profit Margin: 38.04% ($248.03 million Gross Profit / $651.93 million Revenue).
• Operating Profit Margin: 6.88% ($44.88 million Operating Income / $651.93 million Revenue).
• Net Profit Margin: 6.37% ($41.53 million Net Income / $651.93 million Revenue).

The most recent quarterly data, Q3 2025, reinforces this upward trajectory, showing a net income surge of 86.8% year-over-year to $13.72 million, with a Net Margin of 5.6% on $182.01 million in revenue..

Operational Efficiency and Margin Trends

The trend in profitability is defintely positive, suggesting the company's strategic focus on high-value energy efficiency and grid services is paying off. The gross margin is a major highlight, improving to 39.4% in Q2 2025 from 34.6% in the same quarter last year, a gain driven by a favorable revenue mix and solid project execution. This shows strong cost management (Cost of Goods Sold) within the core service delivery. The Energy segment is the engine, contributing $154.75 million in Q3 2025 revenue.

However, the gap between the Gross Margin (nearly 38% TTM) and the Operating Margin (6.88% TTM) tells you where the operational costs are concentrated. General and administrative (G&A) expenses rose 33% in Q2 2025, attributed to increased wages, incentive compensation, and higher stock-based compensation, which are necessary investments to support the rapid growth, but they compress the operating profit (EBIT). The TTM Operating Margin of 6.07% as of November 2025 is a significant improvement from 4.72% in 2024, confirming the turnaround is gaining traction.

Peer Comparison: WLDN vs. Industry

When you compare Willdan Group, Inc.'s profitability with its peers in the Engineering & Construction and professional services space, the picture is nuanced. While the company's profitability is on an uptrend, it still sits in the middle of the pack for operating efficiency, but its valuation suggests high growth expectations.

Here is a look at the TTM Operating Margin, which is a clean measure of core business efficiency, against key competitors:

Willdan's 6.07% TTM Operating Margin is competitive, nearly matching Tetra Tech's 6.17%, but it trails Stantec's 7.96%. This suggests there is still room for Willdan to streamline its operating expenses (OpEx) as it scales. Also, the company's Price-to-Earnings (P/E) ratio of 34.5x is notably higher than the industry average of 23.7x, indicating that investors are pricing in substantial future earnings growth to justify the current valuation premium.

Next Step: Finance should model the impact of a 100 basis point (1%) improvement in G&A efficiency on the 2025 Adjusted EBITDA guidance, which is currently projected between $70 million and $73 million.

Debt vs. Equity Structure

You want to know how Willdan Group, Inc. (WLDN) is funding its impressive growth, and the short answer is: mostly through retained earnings and a very conservative use of debt. The company's balance sheet is defintely strong, showing a clear preference for equity and operational cash flow over high leverage.

As of the latest trailing twelve months data, Willdan Group, Inc. carries a total debt of about $67.88 million, which is quite manageable given their scale and recent performance. Breaking that down further, the long-term debt portion was approximately $57.179 million as of July 2025, with a much smaller $2.5 million classified as the current portion of long-term debt. This structure shows that the bulk of their obligations are not due in the immediate near-term, which is a good sign for liquidity.

Low Leverage: A Clear Competitive Edge

The most telling metric here is the Debt-to-Equity (D/E) ratio, which measures how much debt a company is using to finance its assets compared to the value of its shareholders' equity. Willdan Group, Inc.'s D/E ratio stands at a remarkably low 0.24. Here's the quick math: for every dollar of equity, they are only using 24 cents of debt.

This is a massive advantage when you compare it to the broader Industrials sector, where the average Debt-to-Equity (adjusted) is closer to 0.583, or 58.3%. Willdan Group, Inc. is operating with significantly less financial risk than its peers. They are simply not reliant on external financing to fuel their operations, which gives them immense flexibility, especially in a tightening credit environment.

• Willdan Group, Inc. D/E Ratio: 0.24
• Industrials Sector Average D/E Ratio: 0.583
• Low D/E means lower interest expense and higher profit retention.

Financing Growth: Debt Capacity and Acquisitions

Willdan Group, Inc. uses debt strategically, primarily to fund their targeted acquisition strategy, not just for day-to-day working capital. In September 2023, the company completed a key refinancing, putting in place a new credit agreement that includes a $100 million term loan and a $50 million revolving credit facility, both maturing in September 2026. This facility is the backbone of their debt structure.

Their financial discipline is evident in their net debt position. As of the third quarter of 2025, the company had reduced its net debt to only $16 million, a sharp drop from earlier in the year, and their leverage ratio (Net Debt to Adjusted EBITDA) was down to a very conservative 0.2x. This reduction, including a $28 million total debt reduction during Q2 2025, reinforces their commitment to disciplined capital deployment. They have a healthy balance of available liquidity, which stood at a total of $172 million in Q2 2025, giving them plenty of dry powder for future acquisitions or to weather any economic storms. This is a company that is growing fast but doing it responsibly.

Liquidity and Solvency

You want to know if Willdan Group, Inc. (WLDN) can cover its near-term obligations, and the short answer is yes, they are in a strong liquidity position as of the third quarter of 2025. Their operational efficiency is converting record earnings into solid cash flow, which is exactly what you want to see.

For a services company like Willdan Group, Inc., liquidity is all about managing the gap between paying your people and getting paid by your clients. Their balance sheet metrics for the 2025 fiscal year show a healthy cushion, which gives management the flexibility to pursue new growth opportunities, like their recent acquisitions.

Current and Quick Ratios: A Strong Buffer

The first place I look is the Current Ratio (Current Assets / Current Liabilities), which tells us if a company has enough assets to cover its debts due in the next year. Willdan Group, Inc.'s Current Ratio was approximately 1.6x in Q2 2025, which is right in the sweet spot for a stable, growing firm. A 1.6x ratio means they have $1.60 in current assets for every $1.00 in current liabilities.

The Quick Ratio (Acid-Test Ratio) is even more telling because it strips out inventory, which can be hard to liquidate quickly. Willdan Group, Inc.'s Trailing Twelve Month (TTM) Quick Ratio, ending in November 2025, stood at a robust 1.44x. This figure is defintely a green light; it shows their accounts receivable and cash alone are more than enough to meet their immediate bills.

• Current Ratio (Q2 2025): 1.6x
• Quick Ratio (TTM Nov 2025): 1.44x
• Total Liquidity (Q3 2025): $183 million

Working Capital and Cash Flow Efficiency

The key to a strong current ratio is efficient management of working capital, which is the capital available for day-to-day operations. Willdan Group, Inc. has shown a consistent focus here. Their Days Sales Outstanding (DSO) was reported at a disciplined 70 days in Q2 2025, reflecting strong collection practices. That's the quick math on how fast they turn a client invoice into cash in the bank.

This efficiency is translating directly into powerful Free Cash Flow (FCF), which is the cash a company generates after accounting for cash outflows to support operations and maintain its capital assets. For the Trailing Twelve Months ending in Q3 2025, Willdan Group, Inc. generated a substantial $65 million in FCF. That's a huge operational win.

Near-Term Risks and Opportunities

The primary strength is the sheer amount of available capital. Willdan Group, Inc.'s total liquidity-cash plus available credit-stood at an impressive $183 million in Q3 2025. Plus, they expanded their credit facility to $200 million earlier in the year, signaling confidence from their lenders and giving them a massive war chest for future strategic acquisitions.

The only caveat is the valuation pressure. While the cash flow is strong, the Price-to-Free-Cash-Flow ratio was high at 318.7 in Q2 2025, which suggests the market is pricing in a lot of future cash flow growth. So, while the balance sheet is healthy, the stock price demands continued, exceptional FCF performance. You can read more about what's driving this demand in Exploring Willdan Group, Inc.

Valuation Analysis

You are wondering if the run-up in Willdan Group, Inc. (WLDN) is justified, and the short answer is that the market is pricing in significant future growth. While a discounted cash flow (DCF) analysis suggests the stock is undervalued-with one fair value estimate sitting at $132.50-traditional multiples signal a premium compared to peers.

Here's the quick math: Willdan Group, Inc. is trading at a premium on trailing earnings, but the forward-looking picture is more balanced. The market is betting heavily on the company's ability to capitalize on the accelerating demand for electrification and resilient grid infrastructure, which you can read more about in their Mission Statement, Vision, & Core Values of Willdan Group, Inc. (WLDN).

The core valuation ratios for Willdan Group, Inc. (WLDN) as of late 2025 tell a dual story:

• The trailing Price-to-Earnings (P/E) ratio is high at approximately 34.5x, which is notably above the industry average of about 23.7x. This suggests investors are already paying a steep price for past earnings.
• However, the Forward P/E ratio, based on expected 2025 earnings, drops to around 28.38x, indicating a significant expected jump in profitability. That's a strong growth signal.
• The Price-to-Book (P/B) ratio is approximately 4.74, showing the stock trades at a premium to its net asset value, which is common for a fast-growing, service-based business.
• The Enterprise Value-to-EBITDA (EV/EBITDA) ratio is about 22.89x. This multiple is also on the higher end, reflecting the market's expectation that the company will hit its raised 2025 Adjusted EBITDA guidance of between $70 million and $73 million.

Near-Term Price Action and Analyst View

Looking at the last 12 months, Willdan Group, Inc. has been a massive winner. The stock price has surged by over 119.54%, climbing from a 52-week low of $30.43 to a high of $121.00. This dramatic move shows the market's enthusiasm following the company's strong performance and raised guidance, including an Adjusted Diluted EPS target of $3.50 to $3.65 for fiscal year 2025.

To be fair, the volatility is high, with a beta of 1.26, meaning the stock price is about 26% more volatile than the S&P 500. Still, the analyst community is defintely on the bullish side.

The consensus from Wall Street analysts is a clear Buy. The average 12-month price target is $111.50. What this estimate hides is the potential upside; this target suggests a gain of about 14.68% from the recent trading price of $97.23.

One final, simple point: Willdan Group, Inc. does not currently pay a dividend, so your return will be purely from capital appreciation. The dividend yield is 0.00%.

Risk Factors

You're looking at Willdan Group, Inc. (WLDN) after a strong showing in 2025, with full-year adjusted diluted EPS projected between $4.10 and $4.20 per share. But even with that momentum, a seasoned analyst knows to map the risks. The company operates in a high-growth, but also high-stakes, environment, so you need to understand where the vulnerabilities lie.

The primary external risks for Willdan Group, Inc. are tied directly to the very growth drivers that have propelled its stock. The company's focus on energy efficiency and grid services means its fortunes are closely linked to a few massive trends, which can be a double-edged sword. Honestly, relying heavily on a few markets is always a risk.

• Market Concentration Risk: A significant portion of revenue is generated from clients in California, New York, and Nevada. This regional concentration makes Willdan Group, Inc. susceptible to local economic downturns or adverse regulatory shifts in those states.
• Economic Uncertainty: General economic fluctuations can impact government and private sector spending on the infrastructure and energy projects that are Willdan Group, Inc.'s core business.
• Competitive Landscape: The professional technical and consulting services market is defintely highly competitive. Willdan Group, Inc. must consistently innovate to stay ahead of rivals vying for the same utility and government contracts.

Operational and Strategic Vulnerabilities

On the operational and strategic side, two key risks stand out. First, Willdan Group, Inc. has a reliance on data center demand, which, while a massive growth engine-contributing about 15% of commercial segment revenue in fiscal 2025-is a single-point-of-failure risk. If the pace of AI-driven load growth slows, or if a major client shifts strategy, that revenue stream could be pressured. Second, the company's strong financial health, with a total debt-to-equity ratio of 0.42 and a current ratio of 1.6, is generally solid, but the high price-to-free-cash ratio of 318.7 suggests cash flow sustainability is under pressure relative to the stock price.

Here's a quick look at the most recent financial health indicators that highlight the trade-offs:

Mitigation and Actionable Insights

Willdan Group, Inc. is not passive about these risks. Management has been executing a clear strategy to diversify and strengthen its position. They are using strategic acquisitions, like the recent purchase of Alternative Power Generation, Inc. (APG), to bolster their service offerings in areas like electric power solutions and substation work. This helps them move beyond just energy efficiency consulting and into more complex, higher-margin infrastructure projects.

The core mitigation plan is diversification and financial discipline. They are actively working to expand their geographical footprint to reduce dependency on key states. Plus, they are maintaining a strong balance sheet, reducing total debt by $28 million in the second quarter of 2025 alone. This financial flexibility is key for pursuing targeted acquisitions and maintaining a flexible operational model to weather economic downturns. What this estimate hides is the execution risk of integrating those acquisitions, but the intent is clear: reduce concentration risk and increase service differentiation.

Growth Opportunities

You're looking for a clear map of where Willdan Group, Inc. (WLDN) goes from here, and the answer is simple: they are positioned squarely at the intersection of two massive, non-negotiable trends-electrification and the data center boom. This isn't just a cyclical upswing; it's a structural shift that Willdan is actively engineering, not just riding.

The company's most recent guidance, updated in November 2025, reflects this momentum. They've raised their full-year 2025 financial targets significantly, a clear signal of confidence. Here's the quick math: management now expects Net Revenue to land between $360 million and $365 million, with Adjusted EBITDA projected between $77 million and $78 million. That translates to an Adjusted Diluted EPS forecast of $4.10 to $4.20 per share. That's a defintely strong outlook.

Key Growth Drivers and Strategic Moves

Willdan's growth isn't abstract; it's grounded in concrete, high-value projects. The primary driver is the explosive demand for power from AI-driven data centers, which requires massive grid upgrades and resilient infrastructure. Plus, the broader push for electrification in transportation and buildings, often mandated by state and local governments, keeps their core energy solutions segment humming.

To capture this, they've been strategic. Their acquisitions, like APG, have given them a proprietary edge-an AI-driven site selection tool that helps hyperscalers and utilities find optimal land and power connections faster. This innovation can cut data center development costs by up to 30% and reduce interconnect times by 40%. That's a serious competitive advantage (a moat) in a fragmented market.

Recent contract wins show this strategy working at scale:

• A $97 million contract with Alameda County, California, for a comprehensive energy savings performance contract, including HVAC electrification, solar PV, and EV charging stations.
• A $36 million substation project for a Phoenix data center.
• $20 million in grid upgrades for the New York Power Authority (NYPA).
• The multiyear Los Angeles Department of Water and Power (LA DWP) contract is set to ramp up from the fourth quarter of 2025.

Competitive Positioning and Future Outlook

What makes Willdan Group, Inc. a sticky partner for these massive projects is their integrated model-they are a true one-stop energy ecosystem. They combine engineering, consulting, and project management, which is a huge benefit for utilities and government agencies that prefer a single, accountable partner. They also have long-term relationships, like their 24-year history with Alameda County, which creates a high barrier to entry for competitors.

The company's organic growth rate of 20% in net revenue for the third quarter of 2025 tells you all you need to know about current demand. The risk, to be fair, is that they rely heavily on sustained data center demand and favorable economic conditions, but the tailwinds from electrification and grid modernization are powerful enough to support the bullish outlook for now.
