+ 1.1%

Revenuefor the first quarter ended 31 March 2019 amounts to €1,124.0 million, slightly decreasing compared to the same period of 2018 (- 0,5% on reported basis and + 1.1% restated for deconsolidation of North American talc subsidiaries since February 14, 2019). The decrease in organic growth (- 0.9%) is the result of volumes still impacted by a high comparison basis, a challenging market environment, notably in European automotive, refractory and industrial markets, and large destocking in North America. This is partly compensated by a robust price-mix effect in our two business segments (Performance Minerals and High Temperature Materials and Solutions), up + 2.7%, in an inflationary environment.

Revenue also includes a favorable impact of exchange rates of €28.7 million due mainly to the appreciation of the US dollar versus the euro, which compensates a negative perimeter effect of €24.1 million (- 2.1%), of which -€18.1 million from the deconsolidation of our North American talc subsidiaries following their filing for chapter 11.

CURRENT OPERATING INCOME

First quarter 2019 current operating income totaled €109.6 million, down 15.4% compared to the first quarter of 2018, reflecting mainly the lower contribution from volumes (- €22.2 million). It also takes into account the North American talc subsidiaries deconsolidation (- €3.5 million) and the impact of the temporary shutdown of a wollastonite plant in Willsboro, USA, due to production issues (- €3.4 million). Excluding these two items, the current operating margin was 10.4% in the first quarter of 2019 (versus 9.8% on a reported basis). Effect of exchange rates was a positive €6.2 million.

The firm price mix effect of + €30.7 million fully compensated the carry over of inflation of variable costs, with a €30.1 million negative impact, corresponding to a + 5.5% year-on-year inflation (down from + 6.7% year on year in the fourth quarter of 2018).

The fixed costs and overheads improved by 1.3% (€5.9 million), reflecting the positive effect of the decisions concerning ceramic proppants and Namibian operations.

NET INCOME FROM CURRENT OPERATIONS

Net income from current operations amounted to 75.1 million, down 2.6% compared to the first quarter of 2018. It includes a €17.2 million improvement in financial results, mainly due to the full repayment on March 2019 of the €56 million JPY private placement maturing in 2033. The tax charge of - €31.1 million (versus - € 32.6 million in the first quarter of 2018) reflects an effective tax rate of 29.0 % (versus 29.6% in the first quarter of 2018).

Net income from current operations, Group share, per shareis down - 2.8% to €0.95.

NET INCOME

Other income and operating expenses, net of taxes, amounted to - €7.9 million in the first quarter of 2019. They include €3.3 million net additional costs associated with the temporary shutdown of the Willsboro plant in the USA. Consequently net income, Group share, was €67.2 million, down 8.7%.

OUTLOOK

In the current market environment and with a demanding comparison basis in the second quarter, the Group will continue to sustain its performance6 by giving priority to cost reduction and cash generation.

Operations at Willsboro should restart mid year. As of today, its full-year impact on net income is expected to be around -€25 million.

Imerys has started to deploy its transformation projects with a view to make the most of its simpler, more customer focused organization to support its future growth.

+ 1.5%

The Performance Minerals business segment's revenue totaled €623.1 million in the first quarter of 2019 (decrease of -1.4% on a reported basis). This change takes into account a significant - €19.3 perimeter effect (-3.1%), mainly due to the deconsolidation of the North American talc subsidiaries. A positive exchange rate effect of €20.6 million (+ 3.3%) helped partly offset this impact. As a result, revenue was down -1.7%like-for-like in the first quarter of 2019. Price - mix remained positive in all regions.

On a like-for-like basis, revenue in the Americas was impacted by weak paper markets and destocking from filtration customers, as well as the temporary shutdown of a wollastonite plant in Willsboro, USA, serving the polymers and coatings business industry. On the opposite, building and infrastructure held up well.

Revenue in EMEA were resilient in an adverse market environment, in particular in the automotive sector, whilst paint demand was supported by a positive mix and paper sales sustained by customers' anticipation of Brexit. Filtration was impacted by destocking and ceramics suffered from lower demand in the Middle East.

Revenue in APAC has benefited from positive volumes and mix effects, as a result of an increasing demand for conductive additives for Lithium-ion batteries in China and South Korea, and strong volumes from filtration for food and pharmaceutical markets. To a lesser extent, an overall softer environment in plastics, rubber and paints, as well as decreasing paper & board markets in Japan impacted revenue.

The High Temperature Materials and Solutionsbusiness segment's revenuetotaled €509.6 million in the first quarter of 2019, a + 0.8% year-on-year increase. It includes a + 11.3 million exchange rate impact (+ 2.2%) and a

-€4.8 million perimeter effect (- 0.9%), mainly related to the disposal of a cat litter business (October 1, 2018), and a non-core fused alumina plant in United Kingdom (March 1, 2019). Like-for-like revenue was stable, despite a particularly high comparison basis in the first quarter of 2018. Strong raw material inflation was successfully offset by price adjustments.

The High Temperature Solutions organic growth was impacted by the decline of major kiln refurbishment projects (petrochemicals, boilers, incinerators industries, etc.) and car production weighing on the foundry market in Europe. This was partly compensated by supportive iron & steel markets and positive momentum in South East Asia, while activity in India softened over the period.

Revenue of Refractory, Abrasives and Construction was stable like-for-like. The decrease in volumes stemmed from weak abrasives and refractory demand, particularly in Germany, where the business area has a significant presence. Meanwhile, the building chemistry business continued to expand globally.
