Caesarstone (Nasdaq: CSTE) reported second-quarter 2026 revenue of US$96.6 million, compared with US$101.1 million in the prior-year quarter. The company described continued softness in North America, partly offset by strength in Australia; on a constant-currency basis, revenue was down about 7.7%.
The quarter showed a sharper profitability picture than the revenue line alone. Gross margin rose to 24.0% from 19.6% a year earlier, while adjusted gross margin reached 26.5% from 19.7%. Adjusted EBITDA loss narrowed to about US$1 million, compared with US$6.4 million a year earlier and US$7.5 million in Q1 2026.
Margin recovery against softer revenue
For the engineered-stone category, Caesarstone's results are a useful operating read because the company is exposed to both market demand and the regulatory pressures now affecting quartz surface products. The improvement in gross margin and the smaller adjusted EBITDA loss indicate progress in profitability even as North American conditions remained soft.
About 44% of Q2 revenue came from the United States. That weighting gives the new US tariff-rate quota on quartz surface products particular importance for the company. The four-year quota took effect August 15, 2026, after the quarter reported. It applies a 25% in-quota duty and a 50% over-quota duty. Caesarstone said the TRQ could raise costs and delay its path to positive adjusted EBITDA.
For a product category sold through slab distributors, fabricators and project supply chains, the distinction between margin recovery and forward cost pressure is consequential. Buyers of an engineered quartz surface are dealing with an industry where supplier operating results can improve while newly effective import measures change the cost and timing of future supply.
Q2 2026 figures reported by Caesarstone
- Revenue: US$96.6 million, versus US$101.1 million in the prior-year quarter.
- Gross margin: 24.0%, versus 19.6% a year earlier.
- Adjusted gross margin: 26.5%, versus 19.7% a year earlier.
- Adjusted EBITDA loss: about US$1 million, versus US$6.4 million a year earlier and US$7.5 million in Q1 2026.
Tariff quota and silicosis exposure
The US tariff measure is one of two forces Caesarstone identified around its outlook. The company operates in a market affected by the new safeguard structure, which buyers can review through the US quartz safeguard TRQ. The 25% in-quota and 50% over-quota rates can alter landed cost calculations for products within the scope of the measure.
The second force is silicosis litigation. Caesarstone faces claims from about 800 individuals alleging injury from respirable crystalline silica dust, including roughly 600 claims in the United States. As of June 30, 2026, it had recorded a US$51.2 million provision for legal settlements and loss contingencies, with US$12.0 million of related insurance receivables.
That exposure sits alongside the wider worker-health debate documented in the California silicosis epidemic report. The reported claims and provision are company-specific, but the underlying issue reaches across engineered stone: cutting and fabrication practices, workplace controls, insurance and legal risk all influence the commercial environment surrounding quartz surfaces.
Caesarstone therefore functions as a bellwether for the category rather than a simple quarterly earnings case. Its figures place improved gross margins next to a US trade measure that may increase costs, and next to litigation provisions linked to respirable crystalline silica dust. Neither factor disappears because the quarter's adjusted EBITDA loss narrowed.
What it means for buyers
For importers and project buyers, Q2 results reinforce the need to distinguish a supplier's reported margin improvement from the landed-cost conditions of future orders. The TRQ became effective August 15, 2026, so quotations, delivery windows and duty allocation should be checked against the quota and rate structure rather than inferred from a prior quarter's revenue performance.
Contract language can help make that separation explicit. Buyers may want orders to identify tariff responsibility, timing for entry, applicable product scope and the process for any cost adjustment. For fabricators, the same review should connect purchase terms to shop planning and to the controls required when working with engineered stone.
The litigation figures also make compliance a procurement issue, not just a legal one. Suppliers and fabricators should be assessed against the relevant cutting, finishing and installation conditions for quartz surfaces. The commercial question is not simply whether material is available; it is how tariff costs, production conditions and claims exposure are reflected through the supply chain. Caesarstone's Q2 report shows those pressures operating at the same time as margin recovery.
The reported Q2 figures also give purchasing teams a defined reference point for discussions with distributors and fabricators. Revenue was US$96.6 million, gross margin was 24.0%, and adjusted gross margin was 26.5%. Those figures should be treated as reported operating data, alongside the later effective tariff quota and the company's recorded litigation provision.
For long-running specifications, the relevant time window extends beyond a single quarterly result. Buyers can document the material scope, expected entry timing and processing responsibilities at the same time they confirm technical requirements for the finished surface. That approach keeps the cost and compliance questions visible through procurement rather than leaving them to a later handover dispute.
