Strong coatings, weak DIY

01 Running thesis

Two RPMs in one

RPM is working because its commercial and industrial businesses are carrying the load. In Q3 fiscal 2026, Construction Products posted 6.9% organic sales growth, and Performance Coatings posted 5.1% organic sales growth. Those units sell into roofing, wall systems, concrete repair, protective coatings, fireproofing, and infrastructure work.

The problem sits in Consumer. That segment sells brands like Rust-Oleum, DAP, and Zinsser into retail and do-it-yourself channels. In Q3, Consumer organic sales fell 2.4% because DIY demand was soft and RPM was cutting back some lower-value products. Acquisitions helped reported sales, but they did not fix the core volume issue.

The bull case is that RPM can keep turning modest sales growth into faster profit growth. Adjusted diluted EPS rose 62.9% in Q3, while adjusted EBIT rose 48.8%. MAP savings, pricing, and better fixed-cost leverage are helping.

The bear case is that this is not a clean growth story. Management launched the 2026 restructuring action to cut SG&A and rationalize parts of the footprint. That can help margins, but it also shows demand is uneven and execution matters more now.

Apr 2026Q3 fiscal 2026 showed record sales of $1.61 billion, up 8.9%, and adjusted EPS growth of 62.9%. The upgrade is mixed because CPG and PCG grew organically while Consumer organic sales fell 2.4%.
Jan 2026Q2 showed a sharper demand slowdown, with softer DIY demand and longer construction project lead times. Management responded with a cost plan targeting about $100 million in annual savings.
Oct 2025Q1 shifted the story toward growth spending in sales and marketing, but near-term margin pressure rose. Tariffs, healthcare costs, and plant consolidation costs limited the profit benefit from stronger sales.
Jul 2025Q4 fiscal 2025 rebounded from weather disruption and set records for sales, adjusted EBIT, and adjusted EPS. RPM also moved from four reportable segments to three.
Apr 2025Q3 fiscal 2025 was hurt by severe weather, with sales down 3.0% and adjusted EBIT down 29.0%. The miss showed that RPM can still have negative operating leverage when volumes fall.
Jan 2025Q2 fiscal 2025 showed all segments returning to positive volume growth. Management also raised the expected MAP 2025 savings target to $500 million.
02 Business model

Brands plus chemistry

RPM is a holding company. It owns many specialty coatings, sealants, and chemicals businesses. The company makes money by selling branded products to contractors, building owners, distributors, factories, retailers, and home repair shoppers.

The model works best when products solve costly problems. A roof coating, fireproofing system, industrial floor, or corrosion coating can be a small part of a project budget but a big part of avoiding leaks, shutdowns, or safety issues. That gives RPM room to price for value when demand is healthy.

The weaker part is retail DIY. Paints, caulks, primers, and repair products depend more on home project activity and store traffic. When consumers delay projects, RPM can lose volume even if pricing improves.

Management is now balancing growth spending with cost cuts. The 2026 restructuring action is aimed at about $100 million in annual SG&A savings through fewer management layers and footprint rationalization.

03 Product portfolio

What RPM sells

Growth engine

Construction Products Group

This group sells building envelope products, including Tremco roofing systems, Euclid Chemical concrete products, sealants, insulation, and wall system materials. Q3 organic growth was 6.9%, led by North American roofing, wall systems, and concrete admixtures.

Growth engine

Performance Coatings Group

This group sells Stonhard industrial flooring, Carboline corrosion control coatings, and fireproofing products. Q3 organic growth was 5.1%, helped by protective coatings, fireproofing, infrastructure, and emerging market demand.

Cash cow

Consumer Group

This group sells Rust-Oleum paints, DAP caulks and sealants, Zinsser primers, and other retail repair products. The brands are strong, but Q3 organic sales fell 2.4% because DIY demand stayed soft.

Option

Kalzip and metal roofing

RPM announced the acquisition of Kalzip, a metal roofing and facade business. The deal fits RPM's push into commercial building systems.

Steady

Legacy specialty niches

RPM still serves disaster restoration, specialty OEM, industrial wood coating, and other niche markets. These businesses are no longer a separate reportable segment after the June 1, 2025 realignment, and RPM is pruning lower-margin products.

04 Business segments

Latest sales mix

Construction Products Group34%modest
Performance Coatings Group31%modest
Consumer Group35%declining

Segment shares use Q3 fiscal 2026 net sales from the Form 10-Q for the three months ended February 28, 2026. The mix is close, with Consumer the largest by a small margin, but Consumer has the weakest organic trend.

05 Risk factors

What can break

DIY stays weak

High impact · High odds

Consumer organic sales fell 2.4% in Q3 fiscal 2026. If shoppers keep delaying home repair and paint projects, acquisitions may keep hiding weak volumes rather than fixing them. That would make the earnings recovery less durable.

We watchConsumer organic sales growth, retail sell-through, and management comments on DIY traffic.

Restructuring misses the target

High impact · Medium odds

RPM is targeting about $100 million in annual savings from the 2026 restructuring action. The plan includes fewer management layers and footprint rationalization. If savings arrive late, or if service levels suffer, margins may not improve as expected.

We watchQuarterly SG&A as a percentage of sales and updates on the remaining restructuring savings.

Plant moves create drag

Medium impact · Medium odds

Management has already pointed to temporary inefficiencies from plant and warehouse consolidations. These costs can eat into gross margin gains from pricing and MAP savings. The timeline for finishing the footprint rationalizations remains an open question.

We watchGross margin, conversion costs, and any named consolidation costs in quarterly filings.

Construction projects slow

Medium impact · Medium odds

RPM benefits from repair, maintenance, roofing, wall systems, concrete, and infrastructure work. In Q2, management said longer construction project lead times became more pronounced in October and November. If project timing slips again, the strong CPG and PCG trends could cool.

We watchCPG and PCG organic sales growth, backlog comments, and construction project lead-time commentary.

Tariffs and input costs return

Medium impact · Medium odds

Tariffs are a headwind for metal packaging in Consumer and for some epoxy resins and niche chemicals. RPM can raise prices, but not always fast enough. If inflation rises while volumes stay soft, margin gains could fade.

We watchGross margin, price-cost commentary, tariff comments, and Consumer packaging cost updates.
06 Quick answers

In one breath

What does RPM International do?

RPM makes specialty coatings, sealants, roofing systems, flooring, primers, and repair chemicals. Its products are used in commercial buildings, infrastructure, factories, and home improvement projects.

Why is RPM's Consumer segment a concern?

The Consumer segment depends more on do-it-yourself home repair activity. In Q3 fiscal 2026, its organic sales fell 2.4% because DIY demand was soft and RPM was rationalizing products.

What is the 2026 restructuring action?

It is RPM's cost-cutting plan aimed at about $100 million in annual SG&A savings. The plan focuses on management structure changes and footprint rationalization.

What should investors watch next for RPM?

Watch whether CPG and PCG keep growing organically, whether Consumer organic sales stabilize, and whether SG&A savings show up without new plant-move costs. Those signals will show if Q3 was a lasting improvement or a temporary boost.
