Acquisitions carry growth while margins wobble

Q4 sales grew 17% to $371.5 million, but recent acquisitions added $44.1 million of that growth.
Organic growth slowed to 3% in Q4 after 14% in Q3, which makes the base business harder to judge.
Gross margin fell to 27.4% from 29.3% a year ago due to mix and inflation.
Free cash flow was $55 million in Q4 and $170 million for fiscal 2026, giving management room for deals and cash returns.
Data center demand is becoming a real growth lane, with about $13 million of ASME tank shipments in fiscal 2026.

01 Running thesis

Good growth, weaker proof

Worthington had a strong headline year. Fiscal 2026 sales were $1.4 billion, up 20%, and Q4 sales rose 17% to $371.5 million. The catch is quality. In Q4, recent acquisitions added $44.1 million of sales, while organic growth slowed to 3%. That is a sharp step down from 14% organic growth in Q3.

The bull case is still clear. Elgen and LSI are adding sales, WAVE remains a strong joint venture, and Worthington is finding growth in building products tied to data centers. Management said ASME water tanks for liquid cooling shipped about $13 million in fiscal 2026 and expects at least that much in Q1 fiscal 2027 alone.

The bear case is now louder. Gross margin fell to 27.4% from 29.3% a year ago, and management blamed less favorable mix and inflation. ClarkDietrich also remains under pressure from weak nonresidential construction and steel pricing. Worthington is producing cash, raising the dividend, and buying back stock, but investors need to see organic growth recover and margins stabilize.

Jun 2026▼Q4 sales grew 17%, but organic growth slowed to 3% from 14% in Q3. Gross margin fell to 27.4%, so the view shifted toward proving base demand and margin recovery.

Apr 2026→The Q3 10-Q confirmed the sales growth already in the thesis and did not add major new risks. Building Products stayed strong, while equity income was still softer.

Mar 2026▲Q3 improved the case because organic growth reached 14%, with Building Products up 16% excluding acquisitions. Management also gave a clearer data center growth story.

Jan 2026▼The Q2 10-Q confirmed that ClarkDietrich equity income fell sharply, down 57.7% year over year. It also showed gross margin pressure as mix shifted toward lower-margin value streams.

Dec 2025▲Q2 results showed 19% sales growth and the company announced the $205 million LSI acquisition. The update supported the M&A growth case, while Consumer Products stayed cautious.

Oct 2025→The Q1 10-Q showed strong Building Products growth, helped by Elgen and volume gains. That was offset by weaker Consumer Products margins and lower ClarkDietrich equity income.

Sep 2025→Q1 showed strong cooling and construction demand from the A2L refrigerant transition. WAVE stayed strong, but ClarkDietrich and Consumer Products kept the overall view balanced.

Jul 2025▼The FY2025 10-K confirmed a 31.8% full-year decline in ClarkDietrich equity income. It also added focus on customer concentration and AI-related operating risk.

02 Business model

Brands, parts, and joint ventures

Worthington sells two main kinds of products. Consumer Products go through retail channels and include fuel cylinders, torches, helium kits, camping gas, and drywall tools. Building Products go into heating, cooling, cooking, water, roofing, and construction systems.

The company also makes a lot of money through joint ventures. WAVE sells ceiling suspension systems and has been a steady earnings source. ClarkDietrich sells light gauge steel framing, but its profits have been hurt by weak commercial construction and pricing pressure.

Growth comes from three places: new products, productivity work, and acquisitions. The company bought Elgen and LSI to expand Building Products, and management has made clear that M&A is a top use of cash. Share repurchases still happen, but they look more opportunistic than central to the plan.

A key break point is customer and channel exposure. One retail customer accounted for 10.1% of consolidated net sales as of Q2 fiscal 2026. If that customer cuts orders, asks for lower prices, or gives shelf space to rivals, Consumer Products can feel it fast.

03 Product portfolio

What Worthington sells

Steady

Torches, fuel, and outdoor living

Brands such as Bernzomatic and Coleman sell hand torches, fuel cylinders, and camping gas. These products rely on retail demand, so inflation and cautious shoppers can hurt volume.

Option

Balloon Time and celebrations

Balloon Time sells helium kits for parties and events. Management said store count was up 64% from a year ago, and the Balloon Time Mini gained placement in a majority of Walmart stores.

Steady

Drywall and repair tools

Level5 and related tools serve repair and remodel work. This area can weaken when higher rates and tight household budgets slow home projects.

Growth engine

Cooling, refrigerant, and LPG cylinders

These Building Products lines benefited from the A2L refrigerant transition, but Q4 had a hard comparison against high demand last year. Long term, new AC and replacement units can support service demand.

Growth engine

Water tanks and data center cooling

Amtrol and ASME water tanks are tied to liquid cooling for data centers. Worthington shipped about $13 million of ASME tanks for data centers in fiscal 2026 and expects at least that much in Q1 fiscal 2027.

Growth engine

Elgen and LSI building parts

Elgen adds commercial HVAC components, while LSI adds commercial metal roof clips and accessories. Together they drove much of Q4's sales growth, but investors still need proof that they add to profit, not only revenue.

Cash cow

WAVE and ClarkDietrich joint ventures

WAVE remains a major earnings contributor in ceiling suspension systems. ClarkDietrich is more cyclical because it depends on nonresidential construction and steel price conditions.

05 Risk factors

What can go wrong

Organic growth stays weak

High impact · Medium odds

Q4 organic growth slowed to 3% after 14% in Q3. If acquisitions keep masking a slower base business, headline revenue growth will overstate the real demand picture.

We watchOrganic growth in the next two quarters, especially Building Products growth excluding Elgen and LSI.

Margin pressure does not fade

High impact · Medium odds

Gross margin fell to 27.4% from 29.3% a year ago. Management cited mix, purchase accounting at LSI, and inflation. If these costs are not temporary, cash flow and earnings growth could lag sales growth.

We watchGross margin versus 27.4%, plus comments on pricing actions and inflation recovery.

ClarkDietrich remains a drag

Medium impact · High odds

ClarkDietrich has been hurt by weak nonresidential construction and steel pricing pressure. In Q4, lower ClarkDietrich equity income reduced year-over-year adjusted EBITDA by about $7 million. This joint venture matters because equity earnings are a large part of Worthington's profit mix.

We watchClarkDietrich equity income and the Architecture Billings Index, a lead signal for commercial construction.

Consumer spending weakens retail brands

Medium impact · Medium odds

Consumer Products was essentially flat in Q4, with higher prices offsetting lower volume. If shoppers trade down or delay repair and remodel projects, brands like Balloon Time, Bernzomatic, Coleman, and Level5 can lose momentum.

We watchConsumer Products volume trends, retail order commentary, and shelf space at major customers.

M&A adds sales but not enough profit

Medium impact · Medium odds

Elgen and LSI helped drive Q4 sales, but acquisitions also bring integration costs, purchase accounting effects, and execution risk. If acquired businesses do not lift margins and cash flow, the growth strategy becomes less attractive.

We watchBuilding Products adjusted EBITDA margin and management updates on Elgen and LSI integration.

Customer concentration bites

Medium impact · Low odds

A single retail customer accounted for 10.1% of consolidated net sales as of Q2 fiscal 2026. That gives the customer leverage over pricing, placement, and order timing. A lost program or smaller order plan could hit Consumer Products quickly.

We watchAny filing update to top customer sales share and management comments on retail distribution changes.

06 Quick answers

In one breath

What does Worthington Industries actually do?

Worthington makes branded consumer products and building products. Its goods include fuel cylinders, torches, helium kits, drywall tools, water tanks, refrigerant cylinders, HVAC parts, and roofing accessories.

Why did Worthington's Q4 growth look weaker than the headline number?

Sales grew 17% in Q4, but acquisitions added $44.1 million of sales. Organic growth, which strips out that deal impact, slowed to 3%.

How is Worthington tied to data centers?

Worthington makes ASME water tanks used in liquid cooling for data centers. Management said it shipped about $13 million of these tanks in fiscal 2026 and expects at least that much in Q1 fiscal 2027.

What is the biggest thing to watch next?

Watch whether organic growth improves and gross margin stabilizes. If both happen, the M&A and data center story gets stronger. If not, the company may be growing sales without enough profit leverage.
