H.B. Fuller Turns Down $1.4 Billion: The Battle Over What an Adhesives Business Is Really Worth

Activist investor Ancora wants to buy one of H.B. Fuller’s major divisions. Management says the offer is too low. Behind the dispute is a much larger question about corporate breakups, debt, and whether a business can be worth more together than apart.

Adhesives rarely attract much attention from investors. They are not particularly glamorous products, and most consumers probably give little thought to the companies responsible for keeping their flooring, packaging, electronics, automobiles, and buildings together.

But adhesives are an essential part of modern manufacturing. A product that accounts for only a small fraction of a customer’s total costs can be indispensable to the finished product’s performance.

That is part of what makes H.B. Fuller an interesting business.

Founded in 1887 and headquartered in St. Paul, Minnesota, H.B. Fuller has grown into the world’s largest pure-play adhesives company, serving customers across more than 30 market segments in approximately 150 countries.

Now, the company finds itself at the center of a dispute that has little to do with the chemistry of adhesives and everything to do with the economics of ownership.

On October 19, H.B. Fuller announced that its board had unanimously rejected a second unsolicited proposal from investment firm Ancora Holdings Group to acquire its Building Adhesive Solutions division for between $1.2 billion and $1.4 billion in cash.

The offer was larger than Ancora’s original proposal in August. It also represented a meaningful amount of money relative to H.B. Fuller’s overall valuation.

Yet management concluded that the revised price still failed to reflect the division’s long-term potential.

At the same time, the company announced that it would explore possible sales of selected businesses and product lines, with proceeds intended to reduce debt.

The two announcements might initially appear contradictory. H.B. Fuller is refusing to sell a major division while simultaneously examining opportunities to sell other assets.

In fact, that distinction is the heart of the story.

The company is not arguing that every business must remain under its ownership. It is arguing that some assets are more valuable inside H.B. Fuller than they would be in the hands of another buyer.

Ancora disagrees.

And the difference between those two views could ultimately determine how billions of dollars in shareholder value are allocated.

The Offer: $1.4 Billion for a Business Ancora Thinks the Market Is Undervaluing

The disagreement began publicly in August, when Ancora proposed acquiring H.B. Fuller’s Building Adhesive Solutions business for between $1.1 billion and $1.2 billion.

H.B. Fuller’s board rejected that proposal, arguing that it undervalued the business and failed to account for its future growth prospects.

On September 29, Ancora returned with an improved offer.

The revised proposal increased the valuation range to $1.2 billion to $1.4 billion and included a letter from Fortress Investment Group expressing a high degree of confidence in arranging the debt financing required for the transaction.

That was a meaningful development.

One of H.B. Fuller’s objections to the original offer concerned whether Ancora could actually finance and execute the purchase. By obtaining support from a major investment firm, Ancora attempted to address that concern.

But a highly confident financing letter is not the same as fully committed acquisition financing.

The proposal remained nonbinding and subject to additional conditions.

Ancora nevertheless argued that its offer represented compelling value.

According to the firm’s September proposal, the price range valued Building Adhesive Solutions at approximately 8.5 to 9.9 times its trailing EBITDA, or roughly nine times estimated 2026 EBITDA at the upper end of the range.

Ancora also argued that the offer represented approximately half of H.B. Fuller’s equity market value while the division contributed only about one-fifth of consolidated revenue.

That comparison was designed to make the proposed sale look particularly attractive.

If H.B. Fuller could receive cash equivalent to roughly half its equity value by selling a business responsible for only a fifth of revenue, why not take the money?

The answer is that revenue contribution and economic value are not necessarily proportional.

A business generating 20% of a company’s revenue could account for a much larger or smaller share of its future profits, cash flow, or strategic advantages.

And that is precisely where H.B. Fuller’s objections begin.

Why H.B. Fuller Believes the Division Is Worth More

Building Adhesive Solutions supplies specialized products used in construction and related industrial applications.

Its markets include activities tied to building materials, infrastructure, and other construction-related demand.

Those industries are cyclical.

When construction slows, customers may purchase fewer materials. When interest rates rise, financing new projects becomes more expensive. And when developers postpone investments, suppliers can experience weaker order volumes.

But the reverse is also true.

A recovery in construction activity can improve demand without requiring a company to rebuild its entire operating infrastructure.

H.B. Fuller believes its Building Adhesive Solutions business is positioned to benefit from such a recovery.

The company’s August response to Ancora highlighted the division’s 6% organic revenue growth in the second quarter of 2026, alongside a 10% improvement in EBITDA.

Management also pointed to opportunities associated with data center construction and its internal restructuring initiative, Project Quantum Leap.

The argument is straightforward.

Ancora is offering a price based on the business as it exists today, while H.B. Fuller believes the division’s future earnings could be materially higher.

That possibility is not unreasonable.

But investors should distinguish a credible opportunity from a guaranteed outcome.

Construction markets may recover more slowly than expected. Customers may remain cautious. Cost pressures could offset revenue growth. And restructuring initiatives do not always produce their anticipated savings.

H.B. Fuller’s management has therefore made an implicit bet.

By refusing the offer, it is choosing to retain the division and pursue the value it believes can be created over time.

The success of that decision will depend on whether those expected improvements actually occur.

The Most Important Detail Is Hidden in the Factories

One of the strongest arguments against the sale has received relatively little attention.

H.B. Fuller says Building Adhesive Solutions shares manufacturing facilities with other company divisions in more than 30 plants around the world.

That matters enormously.

Imagine a factory producing several types of industrial adhesives for different customers and markets.

The factory has a management team, maintenance personnel, equipment, quality-control systems, warehouses, utilities, and transportation arrangements.

Some of those costs can be shared across multiple product lines.

Now imagine selling one division that uses the factory.

The buyer might acquire the division’s products, customer relationships, and intellectual property. But separating the manufacturing operations could be considerably more complicated.

Would the buyer purchase part of the factory? Would H.B. Fuller continue manufacturing products for the buyer under a supply agreement? Would production need to move elsewhere?

Each possibility introduces costs and operational risks.

A factory that was economically efficient when serving several divisions might become less efficient after one business is removed.

H.B. Fuller refers to these potential losses as dis-synergies.

They are the opposite of the synergies companies often promise when announcing acquisitions.

Synergies arise when combining businesses reduces costs or creates additional revenue.

Dis-synergies arise when separating businesses destroys some of those advantages.

This is a critical consideration because the value of a division inside a larger company may differ substantially from its value as a standalone operation.

Ancora’s offer may appear attractive when compared with the division’s reported EBITDA.

But that comparison becomes less persuasive if separating the business creates additional expenses for H.B. Fuller or requires the buyer to establish duplicate infrastructure.

The economics of the transaction depend on what remains after the separation, not simply on the purchase price.

The Debt Argument Is Harder for Management to Dismiss

Ancora’s strongest argument may have less to do with adhesives and more to do with H.B. Fuller’s balance sheet.

At the end of the third quarter of fiscal 2026, H.B. Fuller reported approximately $1.96 billion in net debt.

Its net-debt-to-adjusted-EBITDA ratio stood at approximately 3.0 times.

That represented an improvement from 3.3 times a year earlier.

The company is making progress.

But debt remains a significant consideration, particularly as H.B. Fuller pursues acquisitions and restructuring initiatives.

Ancora’s proposal offers a relatively direct solution.

Sell Building Adhesive Solutions, receive a substantial cash payment, and use the proceeds to reduce borrowings.

To illustrate the potential effect, consider the upper end of the proposed $1.4 billion valuation.

If H.B. Fuller received the entire amount and applied it to debt, its reported net debt could theoretically fall from approximately $1.96 billion to roughly $560 million.

That is a dramatic reduction.

But it is not a realistic pro forma leverage calculation by itself.

The transaction could generate taxes, advisory fees, separation costs, and other expenses. The company would also lose the earnings and cash flow associated with the sold division.

Both sides of the calculation matter.

Debt would decline, but EBITDA would decline too.

Using Ancora’s implied valuation of approximately nine times estimated 2026 EBITDA, a $1.4 billion purchase price corresponds to roughly $156 million in annual EBITDA.

If that amount were removed from H.B. Fuller’s current trailing adjusted EBITDA of approximately $657 million, the remaining business would generate roughly $501 million, before any dis-synergies, retained costs, or other adjustments.

In a simplified scenario, net debt of $560 million divided by $501 million of EBITDA would produce leverage of approximately 1.1 times.

That is materially lower than the company’s reported 3.0 times.

The illustration is not a forecast. It combines figures from different measurement periods and assumes the entire purchase price is available for debt reduction.

Nevertheless, it explains why Ancora believes the transaction could materially strengthen the balance sheet.

The financial attraction is real.

The dispute concerns what H.B. Fuller would sacrifice to obtain it.

Project Quantum Leap: A Restructuring Program With a Lot Riding on It

H.B. Fuller’s defense relies partly on an initiative with an ambitious name: Project Quantum Leap.

The program is intended to improve the company’s operating efficiency, optimize its manufacturing footprint, reduce costs, and support higher margins.

For an industrial business operating across numerous countries and product categories, even modest improvements in manufacturing productivity can have meaningful financial consequences.

Consider a company generating $3.5 billion in annual revenue.

A one-percentage-point improvement in operating profitability, all else equal, would represent approximately $35 million in additional annual operating profit.

A two-percentage-point improvement would represent $70 million.

Those figures are illustrative, not specific company guidance. But they show why manufacturing efficiency matters so much at H.B. Fuller’s scale.

The company has already reported evidence of progress.

In the third quarter of 2026, H.B. Fuller generated $938 million in revenue, an increase of 5.2% from the prior year.

Organic revenue increased 4.4%.

Adjusted EBITDA rose 9% to $187 million, while the adjusted EBITDA margin improved to 19.9%.

That was an 80-basis-point improvement from the comparable period a year earlier.

The company also reported diluted adjusted earnings per share of $1.52, up 21% year over year.

Those results suggest that pricing actions and restructuring savings are contributing to improved profitability.

However, there is an important qualification.

Third-quarter pricing increased revenue by 7.4%, more than offsetting lower sales volume.

That means the company’s organic growth was driven by higher prices rather than an increase in the quantity of products sold.

Price-led growth can be valuable, particularly when a company has differentiated products and strong customer relationships.

But sustained volume weakness can eventually become a problem.

Customers may reduce consumption, delay purchases, or seek alternative suppliers.

H.B. Fuller has demonstrated an ability to protect margins through pricing and cost management.

The next challenge is generating more consistent volume growth.

That is especially important to the argument that Building Adhesive Solutions will become significantly more valuable over time.

The Data Center Opportunity Is Real, but It Should Not Be Exaggerated

One of the more interesting elements of H.B. Fuller’s defense is its reference to data center construction.

The expansion of artificial intelligence and cloud computing has created substantial demand for data center infrastructure.

Those facilities require extensive construction materials, electrical systems, insulation, flooring, sealants, and other specialized products.

Adhesives and related materials can play important roles in these applications.

For a supplier such as H.B. Fuller, the growth of data center construction could create additional demand.

But investors should be careful about treating every industrial supplier as a direct beneficiary of the AI boom.

The relevant questions are how much revenue H.B. Fuller currently generates from data center-related applications, how quickly that business is growing, and what margins it earns.

The company has identified data center construction as a potential tailwind, but the information available does not establish that it represents a dominant share of Building Adhesive Solutions revenue.

That distinction matters.

A growing end market can be attractive without transforming the economics of an entire division.

The opportunity should be evaluated through actual orders, revenue, and profitability rather than through the popularity of artificial intelligence as an investment theme.

Ancora’s Argument Is Not Entirely About the Sale Price

Activist investors frequently focus on the difference between what a company is worth in the stock market and what its individual businesses might be worth if sold separately.

This is sometimes described as a sum-of-the-parts valuation.

The idea is simple.

A diversified company may own several businesses with different growth rates, margins, and competitive positions.

Investors may value the combined company at a relatively modest multiple because its structure is complicated or because weaker divisions obscure the performance of stronger ones.

Selling or separating individual businesses can sometimes reveal value that the stock market has not fully recognized.

Ancora is effectively making that argument about H.B. Fuller.

The firm believes Building Adhesive Solutions has a value that is not adequately reflected in the parent company’s share price.

By offering cash for the division, Ancora is attempting to demonstrate that value through an actual transaction proposal.

But sum-of-the-parts analysis has an important limitation.

Businesses are not always independent pieces that can be separated without consequence.

Shared factories, distribution systems, management teams, customer relationships, and purchasing arrangements can make the combined company more efficient than the individual businesses would be separately.

A breakup can reveal value.

It can also destroy value.

The correct answer depends on the particular economics of the businesses involved.

For H.B. Fuller, the shared manufacturing network makes that question especially important.

The Market Check Is a Quiet Concession

Although H.B. Fuller rejected Ancora’s revised offer, the company also announced that it would explore potential sales of selected businesses and product lines.

That decision deserves attention.

Management is effectively acknowledging that portfolio simplification may create shareholder value.

The company intends to examine assets that are less central to its strategic priorities and assess whether selling them would be financially attractive.

The review will consider possible proceeds, tax consequences, separation costs, operational disruption, and the effects on Project Quantum Leap.

H.B. Fuller expects to complete the market check by the end of 2026.

It has not identified which businesses might be sold or estimated how much money those transactions could generate.

The distinction between this review and Ancora’s proposal is important.

Management wants to retain Building Adhesive Solutions while considering the sale of other assets.

Ancora wants the company to sell a major division immediately.

Both approaches could reduce leverage.

But they involve different trade-offs between cash proceeds, future earnings, and operational complexity.

The market check is therefore more than a routine portfolio review.

It represents an opportunity for H.B. Fuller to demonstrate that its preferred strategy can produce meaningful financial benefits without sacrificing the division it considers strategically important.

If the company identifies attractive buyers for noncore businesses, management’s position may become more persuasive.

If the review produces little progress, Ancora may argue that the company is failing to take sufficiently decisive action.

What Would Make a Sale Worthwhile?

The central valuation question is not whether $1.4 billion is a large amount of money.

It is whether that amount exceeds the value H.B. Fuller can generate by continuing to own Building Adhesive Solutions.

Imagine that the division can produce $156 million in annual EBITDA.

At a nine-times multiple, that implies a value of approximately $1.4 billion.

Now suppose Project Quantum Leap and a recovery in construction markets eventually increase the division’s annual EBITDA to $190 million.

At the same multiple, the implied valuation would rise to approximately $1.71 billion.

That would represent more than $300 million in additional value.

But the outcome is uncertain.

If EBITDA instead declines to $130 million, the same nine-times multiple would imply a valuation of approximately $1.17 billion.

The difference between those scenarios is substantial.

And valuation multiples themselves can change as interest rates, market conditions, and investor expectations evolve.

These examples are not forecasts. They illustrate why management and Ancora can reach different conclusions without either side necessarily misunderstanding the arithmetic.

Ancora is emphasizing the certainty of cash consideration today.

H.B. Fuller is emphasizing the possibility of greater value tomorrow.

The decision depends on the probability of achieving that future value, the time required, and the risks involved.

A dollar received today is not economically identical to a dollar received several years from now.

That is why the time value of money matters.

Even if Building Adhesive Solutions becomes worth more in the future, shareholders must consider whether waiting for that outcome offers a sufficiently attractive return.

A Higher Offer Would Change the Debate

Ancora’s revised proposal has not resolved the disagreement.

The firm increased its offer from a range of $1.1 billion to $1.2 billion to a range of $1.2 billion to $1.4 billion.

At the upper end, that represents an increase of approximately 16.7% over the previous maximum.

The improvement is meaningful, but H.B. Fuller’s board still considers it insufficient.

If Ancora returns with a materially higher proposal, the financial trade-off could become more difficult for management to dismiss.

A higher purchase price would increase the potential proceeds available for debt reduction.

It could also compensate for some of the costs and risks associated with separating the business.

But price is not the only consideration.

A credible proposal would need to address financing commitments, transaction conditions, the separation of shared operations, and the treatment of ongoing commercial relationships between the businesses.

The company has repeatedly raised concerns about those issues.

A buyer willing to pay more but unable to complete the transaction would offer little practical benefit to shareholders.

Conversely, a fully financed proposal with a clear separation plan could strengthen Ancora’s position even without an enormous additional price increase.

For now, the public record does not establish that a third proposal will emerge.

It remains a possibility rather than an announced development.

What Investors Should Watch Before Year-End

The next several months could be particularly revealing.

H.B. Fuller expects to complete its market check by the end of 2026.

That review may identify businesses suitable for sale, but there is no guarantee that any transaction will occur.

Investors should also monitor the company’s debt position as it completes its planned acquisition of Advanced Medical Solutions.

Acquisitions can improve a company’s growth prospects while temporarily increasing leverage.

Management has previously expressed confidence in its ability to return leverage to a target range of 2.5 to 3.0 times within two years following completion of the AMS transaction.

Whether that target remains achievable will depend on cash generation, acquisition integration, and broader operating conditions.

Project Quantum Leap is another important measure.

The company’s recent margin improvements are encouraging, but sustained progress will require continued execution.

And Building Adhesive Solutions itself must deliver on management’s expectations.

If organic growth and profitability continue improving, H.B. Fuller’s decision to reject Ancora may become easier to defend.

If performance deteriorates, the rejected offer could become a source of frustration for shareholders.

Ultimately, management’s credibility will depend less on its ability to explain why the proposal was inadequate and more on its ability to produce a better economic outcome.

The MacroHint View

The H.B. Fuller dispute is a useful example of why corporate finance is rarely as simple as comparing an acquisition offer with a stock-market valuation.

Ancora sees an opportunity to unlock value, reduce debt, and simplify a business whose divisions may be worth more individually than the market recognizes.

H.B. Fuller sees a valuable operating platform whose shared infrastructure, growth opportunities, and restructuring initiatives could produce greater returns if the company remains intact.

Both arguments have merit.

Ancora is right to emphasize that shareholders should not be asked to wait indefinitely for promised improvements.

H.B. Fuller is right to consider the costs of separating a division deeply integrated into its manufacturing network.

The company’s latest earnings provide some support for management’s position. Margins are improving, adjusted EBITDA is growing, and leverage has declined.

But those improvements do not automatically establish that rejecting $1.4 billion is the best decision.

The market check offers management an opportunity to demonstrate that it can reduce debt while retaining the businesses it considers most valuable.

If that strategy succeeds, H.B. Fuller may emerge with a stronger balance sheet and a more focused portfolio.

If it fails, Ancora’s proposal may come to look less like an opportunistic bid and more like an opportunity shareholders wish the company had taken seriously.

The real question is not whether H.B. Fuller can obtain $1.4 billion for Building Adhesive Solutions. It is whether keeping the business will ultimately make shareholders more than $1.4 billion better off after accounting for debt, taxes, separation costs, and the value of future earnings.

That is the calculation management must now justify.

And unlike the adhesives H.B. Fuller manufactures, the company’s shareholders may not be willing to remain stuck with the same strategy forever.
