Building products has quietly become one of the sectors restructuring professionals are watching intently. Years of debt-funded acquisitions collided with a slowdown in commercial construction and residential remodeling, leaving several sponsor-backed companies with balance sheets built for an operating environment that never arrived.

Wilsonart LLC has increasingly become one of those names.

Wilsonart is one of North America's largest manufacturers of decorative laminates, engineered surfaces, quartz, solid surfaces and adhesives used in commercial buildings and residential remodeling. Its products are found in office buildings, schools, hospitals, hotels, retail locations and homes throughout North America. The company is owned by private equity sponsor Clayton, Dubilier & Rice, LLC.

When S&P Global Ratings downgraded Wilsonart to 'B-' on June 24, 2026, it did more than lower the company's rating. It also laid out the financial metrics it will be watching going forward.

S&P said another downgrade could follow if leverage remains above 10x, EBITDA interest coverage falls below 1x, free operating cash flow remains persistently negative, liquidity weakens or the likelihood of a distressed debt restructuring increases.

As of March 31, 2026, Wilsonart's S&P-adjusted leverage stood at 9.8x and EBITDA interest coverage was 1.1x. Put another way, the company sits only 0.2 turns of leverage and 0.1x of interest coverage away from the levels S&P identified as inconsistent with its current rating.

BankruptcyData first highlighted Wilsonart's deteriorating credit profile in July 2024, when Moody's downgraded the company after debt-funded acquisitions pushed leverage to approximately 7.1x EBITDA. Moody's also cited slowing commercial construction, acquisition integration risk and elevated leverage.

Things continued moving in the wrong direction throughout 2025.

In July 2025, S&P downgraded Wilsonart after adjusted leverage reached approximately 8.9x, free operating cash flow turned negative and demand remained weak across both remodeling and new construction.

By March 2026, leverage had climbed again, this time to 9.8x. That's roughly 2.7 turns of additional leverage in less than two years. Every ratings action over that period pointed back to the same issues: weaker end markets and a capital structure built around a construction recovery that never materialized.

The Cornerstone Comparison

Wilsonart isn't the first Clayton, Dubilier & Rice-owned building products company to find itself in this position.

The closest comparison is Cornerstone Building Brands, Inc., another highly leveraged CD&R portfolio company that manufactures exterior building products including vinyl siding, windows, metal roofing and other residential and commercial construction materials.

Like Wilsonart, Cornerstone entered this cycle carrying significant leverage and relying on stronger construction activity to improve its balance sheet.

At year-end 2025, Cornerstone reported adjusted leverage of 10.4x and EBITDA interest coverage of 1.0x, compared with 8.8x leverage and 1.3x coverage a year earlier.

Not long afterward, creditors began organizing. They retained Moelis & Company and Paul, Weiss, Rifkind, Wharton & Garrison LLP ahead of negotiations with CD&R. Cornerstone retained PJT Partners, and by April, S&P had lowered the issuer rating to CCC+. Reports also indicated the company retained AlixPartners and Latham & Watkins LLP to pursue an out-of-court restructuring of nearly $5 billion of debt.

The point isn't that Wilsonart is destined to follow the same path. It's that the underlying credit metrics have become remarkably similar.

Cornerstone reported 10.4x leverage and 1.0x EBITDA interest coverage, with creditors organizing roughly six weeks after that balance sheet date. Wilsonart reported 9.8x leverage and 1.1x EBITDA interest coverage one quarter later. Those are two of the metrics S&P focused on most heavily, and today they're separated by only fractions of a turn.

The comparison begins to diverge when it comes to liquidity. Unlike Cornerstone, S&P still views Wilsonart's liquidity as adequate and expects available cash and revolving credit capacity to support operations over the next twelve months.

S&P-adjusted free operating cash flow to debt improved to approximately negative 2.2%, compared with negative 4.7% a year earlier. The agency expects it to remain around negative 2% during 2026 as working capital improvements and modest earnings growth help offset higher interest expense.

Cornerstone never got that benefit. Even though it didn't face an immediate maturity wall, S&P concluded that continued negative free operating cash flow would eventually force the company to rely more heavily on its revolving credit facility. That concern, more than any looming maturity, is what came before creditors began organizing.

To me, that's the biggest takeaway. A longer runway buys management time, but it doesn't eliminate the need to execute. Cornerstone showed that lenders don't wait for maturities to become a problem. They start paying closer attention when leverage stays elevated, cash generation remains weak and confidence in the capital structure begins to erode.

Wilsonart's products are tied directly to commercial office, education, healthcare, hospitality, retail and residential remodeling activity. Those remain some of the weakest construction markets entering 2026.

The American Institute of Architects' January 2026 Consensus Construction Forecast projects only 1.0% nonresidential construction growth during 2026 and 2.2% during 2027. Most of that growth is expected to come from data centers rather than traditional commercial construction.

Data centers consume concrete, steel, electrical equipment and cooling infrastructure. They don't consume decorative laminates, quartz countertops or engineered interior surfaces.

Healthcare is expected to perform better than most commercial sectors, but it isn't large enough to offset weakness across Wilsonart's broader portfolio, where approximately 77% of 2025 revenue came from laminates and roughly 78% of revenue was generated in the United States.

On paper, Wilsonart serves several different end markets. In reality, most of those markets are still tied to the same construction cycle.

S&P's June downgrade lowered the issuer rating to 'B-', but it also lowered the unsecured issue-level rating to 'CCC' while improving the secured recovery rating. The agency now estimates recoveries of 70% to 90% for first-lien lenders compared with 0% to 10% for unsecured creditors in a default scenario.

The secondary market is pointing in the same direction. Wilsonart's approximately $1.06 billion first-lien term loan due 2031 trades around 90.9, while its $500 million 11% senior unsecured notes due 2032 trade near 79.7, producing a yield of roughly 16.5%.

That pricing suggests investors remain relatively comfortable with the first-lien position while assigning meaningfully more recovery risk to the unsecured notes. At the same time, unsecured bonds trading around 80 are not pricing an imminent restructuring. Instead, they suggest the market believes Wilsonart still has time to improve operating performance before maturities become a more significant issue, while recognizing that if the company ultimately restructures, unsecured recoveries could be materially lower.

S&P also laid out a fairly clear roadmap for what would support a stable outlook. The agency is looking for leverage to move closer to 8x, EBITDA interest coverage to improve toward 1.5x and free operating cash flow to turn sustainably positive. It believes those improvements are achievable through better pricing, stronger operating performance, resolution of production issues at the Temple facility and modest revenue growth.

There are already some signs of progress. Adjusted EBITDA increased approximately 9% in the most recent quarter, and both the first-lien loan and unsecured notes have recovered from earlier lows. The challenge is that even under S&P's more constructive assumptions, leverage is still expected to remain around 9x through 2026. That's certainly an improvement from where the company has been, but it still falls well short of the level that would represent meaningful deleveraging.

Looking Ahead

None of this means Wilsonart is headed for a restructuring. Plenty of companies have worked through comparable leverage with stronger operating performance, asset sales or improved refinancing markets. The point is simply that Wilsonart has reached the part of the credit cycle where lenders begin asking harder questions instead of assuming the company will simply grow its way out of the problem.

Today, the company still has meaningful advantages. Liquidity remains adequate, operations have begun improving and the first significant maturities don't arrive until 2031 and 2032. Those advantages matter, but S&P has also clearly identified the financial levels that would likely lead to another downgrade, and Wilsonart is now sitting very close to each of them.

Cornerstone showed that lenders don't wait for maturities before they begin preparing for a restructuring. They start paying closer attention when leverage remains elevated, cash generation stays weak and confidence in the capital structure begins to erode. Wilsonart already has one of those characteristics. It doesn't yet have the level of cash burn that ultimately pushed Cornerstone's lenders to organize, and whether it gets there is likely to be one of the more interesting building products credit stories to watch over the next twelve months.
