Caesarstone overview

We are a leading manufacturer of high quality engineered quartz surfaces sold under our premium Caesarstone brand. Although the use of quartz is relatively new, it is the fastest growing material in the countertop industry and continues to take market share from other materials, such as granite, manufactured solid surfaces and laminate. Between 1999 and 2012, global engineered quartz sales to end-consumers grew at a compound annual growth rate of 15.8% compared to a 4.4% compound annual growth rate in total global countertop sales to end-consumers during the same period. We believe that our strong brand awareness, leading market position, broad and innovative product offering and comprehensive market support provide us with substantial competitive advantages.

Founded in 1987, Caesarstone is a pioneer in the engineered quartz surfaces industry. Our products consist of engineered quartz slabs that are currently sold in 48 countries through a combination of direct sales in certain markets and indirectly through a network of independent distributors in other markets. In 2011, we acquired our former U.S. distributor and now generate the substantial majority of our revenues in the United States from direct distribution of our products. Our products are primarily used as kitchen countertops in the renovation and new housing end markets. Other applications include vanity tops, wall panels, back splashes, floor tiles, stairs and other interior surfaces that are used in a variety of residential and non-residential applications. Our products’ hardness, as well as their non-porous characteristics, offer superior scratch, stain and heat resistance, making them extremely durable and ideal for kitchen and other applications relative to competing products such as granite, manufactured solid surfaces and laminate. Through our innovative design and manufacturing processes we are able to offer a wide variety of colors, styles, designs and textures.

Since our initial public offering in March 2012, we have further increased our penetration of the U.S. and Canadian markets, which became direct distribution markets for us in 2011, and continued to invest in elevating consumers’ perception of Caesarstone as a premium brand in these markets, including through the introduction of new products and designs. In addition, we have extended our global presence, growing from distributing in 42 countries in 2011 to 48 countries as of March 31, 2013. We have also implemented programs to increase our manufacturing capacity to meet growing consumer demand. We currently expect to complete an approximate 25% capacity increase at our existing manufacturing facilities in Israel in two phases, the first during the fourth quarter of 2013 and the second during the first quarter of 2014. We also expect to construct a new manufacturing facility in the United States with one line that we expect to be operational in the fourth quarter of 2014 and another line subject to the growth of our business. We expect that these lines together would grow our current capacity by approximately 50%.

From 2005 to 2007, our revenue grew at a compound annual growth rate of 37.9%, and during the more challenging global economic environment from 2007 to 2012, at a compound annual growth rate of 17.8%. In 2012, we generated revenue of $296.6 million, net income attributable to controlling interest of $39.6 million, adjusted EBITDA of $69.4 million and adjusted net income attributable to controlling interest of $44.0 million. See “ — Summary consolidated financial and other data” for a description of how we define adjusted EBITDA and adjusted net income attributable to controlling interest and

TABLE OF CONTENTS

reconciliations of net income to adjusted EBITDA and net income attributable to controlling interest to adjusted net income attributable to controlling interest. In 2012, our four largest markets, Australia, the United States, Canada and Israel accounted for 30.0%, 29.3%, 13.6% and 12.3% of our total revenue, respectively.

Industry overview

The global countertop industry generated $73.9 billion in sales to end-consumers in 2012 based on average installed price, which includes installation and other related costs. Sales to end-consumers include sales to the end-consumers of countertops as opposed to sales at the wholesale level from manufacturers to fabricators and/or distributors. The largest countertop markets by sales are Asia Pacific, North America and Western Europe each with sales to end-consumers of between $17.0 billion and $20.1 billion in 2012. Laminate accounted for the largest portion of global countertop sales by volume in 2012, followed by manufactured solid surfaces and granite. Countertops have both residential and non-residential applications. We believe they are primarily installed in residential kitchens, as well in bathrooms and in other commercial applications.

The strength, durability and appearance of engineered quartz, as well as the low maintenance it requires, make it ideal for kitchen and bathroom applications, as well as for other applications such as floors, sinks, stairs and walls. In July 2012, quartz received the highest overall score among countertop materials from Consumer Reports Magazine, a leading provider of third-party consumer product reviews, based on performance in several tests, including resistance to staining, heat, cutting and abrasions, as well as price. Between 1999 and 2012, global engineered quartz sales to end-consumers grew at a compound annual growth rate of 15.8%. In comparison, global countertop sales to end-consumers grew at a compound annual growth rate of 4.4% during the same period. As of 2012, engineered quartz had penetrated only 5.0% of the global countertop market by volume and is in the early stages of penetration in most markets compared to other countertop materials, such as granite, manufactured solid surfaces and laminate. Engineered quartz penetration of the global countertop market by sales increased from 2.1% in 1999 to 8.2% in 2012. We believe that growth in the engineered quartz surfaces market is being driven by increasing awareness of the material’s superior quality and characteristics.

Current penetration of engineered quartz surfaces by geographic region varies considerably. For example, in the United States, which accounted for 20% of global countertop sales to end-consumers in 2012, engineered quartz surfaces have penetrated approximately 6% of the countertop market by volume. In certain markets, including Australia and Israel, engineered quartz surfaces have already significantly penetrated the market and represented 35% and 85% of the total countertop market by volume in these countries in 2012, respectively. These levels highlight the penetration opportunity available to engineered quartz.

The engineered quartz surface manufacturing industry is highly fragmented. Engineered quartz surface manufacturers usually sell quartz slabs to a network of distributors that resell primarily to fabricators. Typically, fabricators are hired by contractors, developers and end-consumers to install the slabs at a project site. The engineered quartz surfaces manufacturing industry is characterized by limited vertical integration with few manufacturers controlling their own distribution or pursuing a global brand strategy.

Demand for countertops is primarily driven by the renovation and remodeling of existing homes and the construction of new homes, which are affected by changes in national and local economic conditions, demographics and unemployment levels. Despite the recent economic downturn, we believe that the home building and renovation and remodeling market has started to recover in the United States, which will help drive long-term demand for countertops. We also believe that rising incomes in developing areas such as China and Latin America will contribute to growing long-term demand for countertops.

Our strategy

We intend to pursue the following strategies in order to enhance our product brand and market share, build economies of scale in our business, and grow our revenues and net income:

TABLE OF CONTENTS

Our products

Our products are generally marketed under the Caesarstone brand. Our engineered quartz slabs generally measure 120 inches long by 56½ inches wide with a thickness of ½ of an inch, ¾ of an inch or 1¼ inches. Engineered quartz surfaces are typically comprised of approximately 90% natural crushed quartz and approximately 10% polyester and other polymer resin and pigments. Our products’ quartz composition gives them superior strength and resistance to heat, scratches, cracks and chips. Polyester and other polymer resins, which act as a binding agent in our products, make our products non-porous and highly resistant to stains. Pigments act as a dyeing agent to vary our products’ colors and patterns.

We engineer our products with a wide range of colors, finishes, textures, thicknesses and physical properties, which helps us meet the different functional and aesthetic demands of end-consumers. We offer a wide spectrum of design options in the engineered quartz surface industry with different colors, textures and finishes designed to appeal to end-consumers’ preferences. Our designs range from fine-grained patterns to coarse-grained color blends with a variegated visual texture. Through offering new designs, we capitalize on the Caesarstone brand name and foster our image as a leading innovator in the engineered quartz surface industry.

Our product offerings include four collections, each of which is designed to have a distinct aesthetic appeal. Each product collection is designed, branded and marketed with the goal of reinforcing our products’ premium quality.

We introduced our original product collection, Classico, in 1987, and today, this collection accounts for the substantial majority of our sales. Within this product collection, we offer approximately 70 different colors, with three textures and three thicknesses generally available for each of the collection’s colors. We have since introduced three additional product collections, Concetto, Motivo and Supremo, which are marketed as specialty high-end product collections. The Concetto product collection, launched in 2003, features engineered quartz surfaces with hand-incorporated semi-precious stones. We launched our Motivo product collection in 2009, which features a range of patterned textures that can be customized. In July 2010, we launched our Supremo product collection that is characterized by unique designs inspired by semi-precious stones. We believe our specialty product families increase our brand’s exposure to the entire product supply chain and, through eye-catching aesthetics, raise the profile of all of our products among end-consumers. We also regularly introduce new colors and designs to our product collections based on consumer trends. In 2012, we introduced a total of 12 new colors to our Classico and Supremo collections.

A key focus of our product development is a commitment to substantiating our claim of our products’ superior quality, strength and durability. Our products undergo regular tests for durability and strength internally by our laboratory operations group and by external accreditation organizations. Many of our products are accredited by the National Sanitation Foundation (NSF), a U.S. non-profit, non-governmental organization overseeing standards development and product safety certifications. Our NSF Standard 51 certification certifies our products as safe for use in food preparation and easy to clean and sanitize. In addition, our products are certified as a low volatile organic compound product by GREENGUARD Indoor

TABLE OF CONTENTS

Air Quality, an independent, non-profit accreditation organization. Our products have been consistently highly ranked by the United States Green Building Council for their compliance with environmental standards, which allows contractors to receive Leadership in Energy and Design (LEED) points for projects incorporating our products.

Distribution

Direct distribution markets

We currently have direct sales channels in Australia, the United States, Canada, Israel and Singapore. The first four of these markets accounts for 85.1% of our sales in 2012. Our direct sales channels allow us to maintain greater control over our entire sales channel within a market. As a result, we gain greater insight into market trends, receive feedback more readily from end-consumers regarding new developments in tastes and preferences, and have greater control over inventory management. Our warehouses in each of these countries maintain inventories of our products and are connected to the subsidiary’s sales department. We supply our products primarily to stonemasons, who in turn resell them to contractors, developers, builders and consumers, who are generally advised by architects and designers to use Caesarstone products for a project.

In Israel, where our headquarters and manufacturing operations are located, we distribute our products directly to several local distributors who in turn sell to fabricators. This arrangement minimizes our financial exposure to end-consumers and provides us with significant depth of coverage in the Israeli market. Although we sell our products to distributors in this market, we consider this a direct distribution market due to the warranty we provide to end-consumers in this market, as well as due to our fabricator technical instruction programs and our robust local sales and marketing activities.

In Canada, the United States and Singapore, we have established direct distribution channels in each country with locations in major urban centers complemented by various sub-distributor arrangements in certain areas of the United States. Similar to Australia, in each of these markets, we and our sub-distributors supply our products generally to stonemasons who in turn resell them to contractors, developers, builders and consumers, who are generally advised by architects and designers to use Caesarstone products for a project.

Indirect distribution markets

We distribute our products in other territories in which we do not have a direct sales channel through third-party distributors, who generally distribute our products on an exclusive or non-exclusive basis in a specific country or region to fabricators. Fabricators sell our products to contractors, developers, builders and consumers. In most cases, we engage one distributor to serve a country or region. Today, we sell our products in over 40 countries through third-party distributors. Sales to third-party distributors accounted for 13.4% of our revenues in 2012, after our shift to direct distribution in the United States and Canada in the first half of 2011. This strategy often allows us to accelerate our penetration into multiple new markets. Our distributors typically have prior stone surface experience and close relationships with fabricators, stonemasons, builders and contractors within their respective territory.

We work closely with our distributors to assist them in preparing and executing a marketing strategy and comprehensive business plan. Our distributors are responsible for the sales and marketing of our products and providing technical support to their customers within their respective territories. To assist distributors in the promotion of our brand in these markets, we provide our distributors with marketing materials and in certain cases, monetary participation in marketing activities. Our distributors devote significant effort and resources to generating and maintaining demand for our products along all levels of the product supply chain in their territory. To this end, distributors use our marketing products and strategies to develop relationships with local builders, contractors, developers, architects and designers.

TABLE OF CONTENTS

Sales and marketing

Sales

In our direct markets, we primarily sell directly to fabricators (with limited sales to sub-distributors in the United States and Australia), such as in Australia where we sell our products through our Australian subsidiary, in Canada, where we sell our products through our joint venture, in the United States where we sell our products through our U.S. subsidiary and in Singapore, where we sell our products through our Singaporean subsidiary. Similar to our indirect markets, in Israel, we sell to a limited number of distributors who sell our products to fabricators; however, we consider this a direct market due to our warranty program, our fabricator technical instruction program and our sales and marketing operations in this country. In our indirect markets we sell to third-party distributors who in turn sell our products to fabricators for sizing, fabricating and installation at a project site. In both cases, we manufacture engineered quartz slabs on a purchase order basis and ship our products from our two manufacturing facilities in Israel.

In our indirect sales markets, we sell our products to distributors who are responsible for selling our products to fabricators. In some cases, our distributors sell to sub-distributors located within the territory who in turn sell to fabricators. Unlike distributors, sub-distributors do not engage in brand promotion activities and their activities are limited to sales promotion, warehousing and distributing to fabricators or other customers. We do not control the pricing terms of our distributors’ or sub-distributors’ sales to fabricators. As a result, prices for our products for fabricators vary among markets.

In recent years, our sales department, which is based in Israel, has focused on penetrating new markets, as well as further developing our key growth markets. We have developed a comprehensive methodology for evaluating and entering new markets. In particular, we analyze several factors within a market, including existing demand for stone products supported by stone installation capabilities, gross domestic product per capita, the competitive landscape and the economic growth rate. We focus our efforts on those markets that we believe offer significant growth opportunity for our products. Potential distributors are evaluated based on their experience in the surface products industry, logistics and distribution capabilities and suitability to market our products. During the past two years, we significantly increased the number of countries where our distributors operate by appointing distributors in several new countries on an exclusive or non-exclusive basis, including Brazil, Russia and Turkey. We intend to continue to penetrate new markets in collaboration with distributors.

During the past eight years, we have also significantly increased our revenues within our key existing markets, Australia, the United States, Canada and Israel. We believe our products still have significant growth opportunities in Australia, Canada and the United States. We intend to continue to invest resources to further strengthen and increase our penetration in each of these markets.

In the future, we may enter into agreements with home furnishing retailers to be their supplier of quartz countertops and may agree to do so without placing our brand on such products. Pursuant to such agreements, we may also agree to acquire other countertop materials from third parties and to be responsible for fabricating and installing countertops.

Marketing

We position our engineered quartz surfaces as premium branded products in terms of their designs, quality and pricing. Through our marketing, we seek to convey our products’ ability to elevate the overall quality of an entire kitchen or other interior setting. Our marketing strategy is to deliver this message every time our customers or end-consumers come in contact with our brand. We also aim to communicate our position as a global leader in engineered quartz surface innovation and technology.

The goal of our marketing activities is to drive marketing and sales efforts through our distributors while creating demand for our products from fabricators and end-consumers, which we refer to as a “push-and-pull demand strategy.” We believe that the combination of both pushing our products through all levels

TABLE OF CONTENTS

of the product supply chain while generating demand from end-consumers differentiates us from our competitors in the engineered quartz and surface material industries.

We believe that by localizing our marketing activities at the distributor level, we increase the global exposure of our brand while tailoring marketing activities to the individual needs, tastes and preferences of a particular country. As such, marketing activities across our markets differ as we aim to promote sales among those who have the greatest influence on public perception in each market.

We and our distributors implement a multi-channel marketing strategy in each of our territories and market not only to our direct customers, but to the entire product supply chain, including fabricators, developers, contractors, kitchen retailers, builders, architects and designers. We use multiple marketing channels, including advertisements in home interior magazines and websites, the placement of our display stands and sample books in kitchen retails stores and our company website. Through our Caesarstone University program we educate fabricators and stonemasons about our products, their capabilities and installation methods through manuals and seminars. As a result, our markets benefit from highly trained fabricators and stonemasons with a comprehensive understanding of our products and the ability to install our products in a variety of applications.

Our marketing materials are developed by our central marketing department in Israel and the substantial majority of our distributors use these materials in their respective local market, which helps ensure the consistency of the Caesarstone brand globally. We offer our distributors a refund of a small percentage of their total purchases from us to buy our marketing materials, such as product brochures, promotional packages, print and online advertising materials, sample books, exhibition infrastructure, signage and stationary and display stands. This provides our distributors with significant flexibility to choose the best marketing strategy to implement in their particular territory. Local marketing departments in Australia and in the United States develop their own marketing materials, in addition to using our marketing materials, due to the size and particular characteristics of these territories. In 2012, we spent $14.9 million on advertising.

Our websites are a key part of our marketing strategy. We operate a global company website that serves as the website for all of our distributors. Certain of our third-party distributors and subsidiaries maintain their own websites, which are in accordance with our brand guidelines and link to our website. Our websites enable fabricators and end-consumers to view currently available designs, photo galleries of installations of our products in a wide range of settings, and read product success stories, which feature high profile individuals’ and designers’ use of our products. We also seek to attract positive attention to our brand and products through a range of other methods, such as home design shows, design competitions, social media and through our products’ use in high profile projects and iconic buildings.

Raw materials and service provider relationships

Quartz, pigment and polyester and other polymer resins are the primary raw materials used in the production of our products. We acquire our raw materials from third-party suppliers. Suppliers ship our raw materials to our manufacturing facilities in Israel primarily by sea and all of our raw materials are inspected at the suppliers’ facilities and upon arrival at our manufacturing facilities in Israel. We believe our strict raw material quality control procedures differentiate our products from our competitors because they contribute to our products’ limited number of product defects and the superior quality and appearance of our products.

Our principal raw material, quartz, is acquired from manufacturers generally in Turkey, India, Israel and a number of European countries. We require supplies of particular grades of quartz, including quartzite, for our products. One supplier in Turkey, Mikroman, supplied approximately 55% of our quartzite in 2012. Mikroman has committed to supply us with quartzite at agreed upon prices through the end of 2013 and, thereafter, at prices that will be agreed upon based on then effective market prices through the end of 2014. If we are unable to agree upon prices with Mikroman, Mikroman ceases supplying us with quartzite or if our supply of quartz generally from Turkey is adversely impacted, we would need to locate and

TABLE OF CONTENTS

qualify alternate suppliers, which could take time, increase costs and require adjustments to the appearance of our products. We typically transact business with our suppliers on a purchase order basis. Other than with respect to the quartzite that we obtain from our Turkish supplier, we believe that the raw materials we use are available from additional sources within a relatively short period of time.

Raw quartz must be processed into finer grades of sand and powder before we use it in our manufacturing process. We purchase quartz in two forms: quartz already processed by quartz suppliers and quartz boulders from quartz suppliers, which are then processed by a processor prior to their use in the manufacturing process. We receive such processing services exclusively from our quartz suppliers.

In most cases, we purchase polyester and other polymer resins based on monthly and up to quarterly purchase orders with several suppliers outside of Israel. However, currently, suppliers are unwilling to agree to preset prices for periods longer than one or two months. The cost of polyester and other polymer resins, which generally correlates with oil prices, has fluctuated significantly over the past two years. In the past, we have minimized the impact of these fluctuations on our results of operations through advance purchases of inventory whenever possible and through implementing cost control measures and programs to enhance the efficiency of other elements of our manufacturing operations. From December 2010 to April 2011, there were significant cost increases for future purchases of polyester and other polymer resins although prices have subsequently declined moderately.

Our pigments are purchased in Israel and from suppliers abroad. We are exposed, although to a lesser extent than with resins, to fluctuations in the prices of pigments. Our strategy is to maintain, whenever practicable, multiple sources for the purchase of our raw materials to achieve competitive pricing, provide flexibility and protect against supply disruption.

Manufacturing and facilities

Our products are manufactured at our two manufacturing facilities located in Kibbutz Sdot-Yam in central Israel and Bar-Lev Industrial Park in northern Israel. We completed our Bar-Lev manufacturing facility in 2005, which included our third production line, and we established our fourth production line at this facility in 2007, which doubled our production capacity. Finished slabs are shipped from our facilities to distributors and customers worldwide. We maintain two fully automated production lines at each facility. In the near term, we plan to expand our existing production capacity to meet anticipated demand through the construction of a fifth production line at our Bar-Lev manufacturing facility in Israel and the construction of a new manufacturing facility with capacity for two production lines in the United States. The fifth production line in the Bar-Lev facility is planned to be operational in two phases, the first during the fourth quarter of 2013 and the second during the first quarter of 2014. The first production line in the new U.S. facility is planned to be operational in the fourth quarter of 2014, and the timing of the second production line’s construction is subject to the growth of our business. During the interim period until the expansion projects are complete, we expect to acquire a limited number of basic slab models from third party engineered stone manufacturers to meet demand for our products.

The manufacturing process for our products involves blending approximately 90% natural crushed quartz with approximately 10% polyester and other polymer resins and pigments. Using machinery acquired primarily from Breton S.p.A., the leading supplier of engineered stone manufacturing equipment, together with our proprietary manufacturing enhancements, this mixture is compacted into slabs by a vacuum and vibration process. The slabs are then moved to a curing kiln where the cross-linking of the resin is completed. Lastly, the slabs are gauged, calibrated and polished to enhance shine.

We maintain strict quality control and safety standards for our products and manufacturing process. As a result, we believe that utilizing in-house manufacturing facilities are the most effective way to ensure that our end-consumers receive high quality products. Our manufacturing facilities have several safety certifications from third-party organizations, including an OHSAS 18001 safety certification from the International Quality Network for superior manufacturing safety operations.

Research and development

Our research and development department is located in Israel and is comprised of 12 employees with extensive experience in engineered quartz surface manufacturing, polymer science, engineering, product design and engineered quartz surface applications. A small portion of our research and development efforts has benefited from grants from the Office of the Chief Scientist in the Israeli Ministry of Industry, Trade and Labor. In 2012, research and development costs, net of participation by the OCS, accounted for approximately 0.7% of our total revenues.

The strategic mission of our research and development team is to develop and maintain innovative and leading technologies and top quality designs, develop new and innovative products according to our marketing department’s roadmap, increase the cost-effectiveness of our manufacturing processes and raw materials, and generate and protect company intellectual property in order to enhance our position in the engineered quartz surface industry. We also study and evaluate consumer trends by attending key exhibitions and hosting international design workshops in-house with market and design specialists from around the world. For example, in March 2010, our research and development team developed our “Pure White” product in response to the increasing demand for white surfaces in residential and non-residential applications. In addition, the introduction of our Supremo collection in July 2010 and our supernatural designs within our Classico collection at the end of 2012 were the result of a new proprietary technologies developed by our research and development department, which allows for the creation of unique designs inspired by natural stones.

Competition

We believe that we compete principally based upon product quality, new product development, brand awareness, pricing, customer service and breadth of product offerings. We believe that we differentiate ourselves from competitors on the basis of our signature product designs, our ability to offer our products in major markets globally, our focus on the quality of our product offerings, our customer service oriented culture, our high involvement in the product supply chain and our leading distribution partners.

The dominant surface materials used by end-consumers in each market vary. Our engineered quartz surface products compete with a number of other surface materials such as granite, laminate, marble, manufactured solid surface, concrete, stainless steel, wood and technical ceramic, a new countertop surface material entrant. The manufacturers of these products consist of a number of regional and global competitors. Some of our competitors may have greater resources than we have, and as a result, may adapt to changes in consumer preferences and demand more quickly, devote greater resources to design innovation and establishing brand recognition, manufacture more versatile slab sizes and implement processes to lower costs.

The engineered quartz surface market is highly fragmented and is also served by a number of regional and global competitors. We also face competition from low-cost manufacturers in Asia, particularly in Australia, and the United States. Large multinational companies have also invested in their engineered quartz surface production capabilities. We believe that we are likely to encounter strong competition from these competitors as a result of consolidation in the industry in the future. Such consolidation is likely to occur as a result of the economies of scale associated with engineered quartz manufacturing that are becoming important to remain competitive in an increasingly global engineered quartz surface market and will be increasingly important as the engineered quartz market matures in the future.

Adjusted EBITDA and adjusted net income attributable to controlling interest are metrics used by management to measure operating performance. Adjusted EBITDA represents net income excluding finance expenses, net, taxes on income, depreciation and amortization, equity in losses of affiliate, net, excess cost of acquired inventory, share-based compensation expense, IPO bonus, Caesarstone USA contingent consideration adjustment, litigation gain and Microgil loan and inventory write down.

TABLE OF CONTENTS

Adjusted net income attributable to controlling interest represents net income attributable to controlling interest excluding excess cost of acquired inventory, litigation gain, IPO bonus, Caesarstone USA contingent consideration adjustment, Microgil loan and inventory write down, share-based compensation expense plus adjustment for the related tax impact. We present adjusted EBITDA as a supplemental performance measure because we believe it facilitates operating performance comparisons from period to period and company to company by backing out potential differences caused by variations in capital structures (affecting interest expenses, net), changes in foreign exchange rates that impact financial asset and liabilities denominated in currencies other than our functional currency (affecting finance expenses, net), tax positions (such as the impact on periods or companies of changes in effective tax rates) and the age and book depreciation of fixed assets (affecting relative depreciation expense). Adjusted EBITDA also excludes equity in losses of affiliate, net, because we believe it is helpful to view the performance of our business excluding the impact of our U.S. distributor, which we did not control, and because our share of the net income (loss) of the U.S. distributor includes items that have other been excluded from adjusted EBITDA (such as finance expenses, net, tax on income and depreciation and amortization). In addition, adjusted EBITDA and adjusted net income attributable to controlling interest exclude the impact of share-based compensation and a number of items that we do not believe reflect the underlying performance of our business. Because adjusted EBITDA and adjusted net income attributable to controlling interest facilitate internal comparisons of operating performance on a more consistent basis, we also use adjusted EBITDA and adjusted net income in measuring our performance relative to that of our competitors. Adjusted EBITDA and adjusted net income attributable to controlling interest are not measures of our financial performance under GAAP and should not be considered as alternatives to net income, operating income or any other performance measures derived in accordance with GAAP or as alternatives to cash flow from operating activities as measures of our profitability or liquidity. We understand that although adjusted EBITDA and adjusted net income attributable to controlling interest are frequently used by securities analysts, lenders and others in their evaluation of companies, adjusted EBITDA and adjusted net income have limitations as analytical tools, and you should not consider them in isolation, or as substitutes for analysis of our results as reported under GAAP. Some of these limitations are:

Risk factors

Investing in our ordinary shares involves a high degree of risk. You should consider carefully the following risk factors and the risk factors discussed under the section captioned “ITEM 3: Key Information — Risk Factors” in our Annual Report on Form 20-F for the year ended December 31, 2012, in addition to all of the other information included in this prospectus supplement, the accompanying prospectus, the documents incorporated by reference in this prospectus supplement and the accompanying prospectus, and any free writing prospectus that we have authorized for use in connection with this offering, before investing in our ordinary shares. Please also refer to the section in this prospectus supplement entitled “Forward-looking statements.” Each of these risk factors could harm our business, financial condition or operating results, as well as decrease the value of an investment in our ordinary shares.

Risks related to our ordinary shares and the offering

The controlling share ownership position of Kibbutz Sdot-Yam will limit your ability to influence corporate matters.

Following this offering, Kibbutz Sdot-Yam will beneficially own 52.7% of our ordinary shares and will have the voting power to control the entire composition of our board of directors, which currently has 10 members and may have a maximum of 11 members (other than our two external directors and two independent directors, each of whom was nominated for a three-year period ending in June 2015 and November 2014, respectively). Kibbutz Sdot-Yam has the right to propose for nomination an additional member to our board of directors. If Kibbutz Sdot-Yam proposes such member, and he or she is elected at a general meeting of our shareholders, our board of directors will consist of 11 members. As a result of this concentration of share ownership, Kibbutz Sdot-Yam acting on its own has sufficient voting power to control all matters submitted to our shareholders for approval that do not require a special majority vote, including:

This concentration of ownership of our ordinary shares could delay or prevent proxy contests, mergers, tender offers, open-market purchase programs or other purchases of shares of our ordinary shares that might otherwise give you the opportunity to realize a premium over then-prevailing market price of our ordinary shares. The interests of Kibbutz Sdot-Yam may not always coincide with the interests of our other shareholders. This concentration of ownership may also adversely affect our share price.

The market price of our ordinary shares could be negatively affected by future sales of our ordinary shares.

As of March 31, 2013, we had 34,593,529 ordinary shares outstanding of which, immediately following this offering, 19,456,250 will not be freely tradeable (or 18,368,750 ordinary shares if the underwriters exercise in full their option to purchase additional shares from the selling shareholders). Sales by us or our shareholders of a substantial number of our ordinary shares in the public market, or the perception that these sales might occur, could cause the market price of our ordinary shares to decline or could impair our ability to raise capital through a future sale of, or pay for acquisitions using, our equity securities. Immediately following this offering, approximately 52.7% of our ordinary shares will be beneficially owned by Kibbutz Sdot-Yam, and can be resold into the public markets in accordance with the requirements of Rule 144, including volume limitations, or pursuant to the registration statement of which this prospectus supplement forms a part.

TABLE OF CONTENTS

In connection with this offering, we have agreed to lock-up restrictions, pursuant to which we, our directors and officers and the selling shareholders will not be permitted to sell any of our ordinary shares for 90 days after the date of this prospectus supplement without the prior consent of J.P. Morgan Securities LLC and Barclays Capital Inc., subject to the exceptions discussed in “Underwriting,” which include the right of our officers to sell up to an aggregate of 245,975 ordinary shares commencing 30 days after the date of this prospectus supplement. Although we have been advised that there is no present intention to do so, J.P. Morgan Securities LLC and Barclays Capital Inc. may, in their sole discretion and without notice, release us, our directors and officers or the selling shareholders from all restrictions in any of the lock-up agreements described above. See “Underwriting.”

Following this offering and the expiration of the lock-up agreement entered into with the underwriters, Kibbutz Sdot-Yam may require us to register an additional 16,415,000 shares under the Securities Act for resale into the public markets (in addition to the 1,825,000 remaining shares registered pursuant to the registration statement of which this prospectus supplement forms a part). All shares sold pursuant to an offering covered by such registration statement or statements will be freely transferable. See “ITEM 7: Major Shareholders and Related Party Transactions — Related Party Transactions — Registration rights agreement” in our Annual Report on Form 20-F for the year ended December 31, 2012.

In addition to these registration rights, as of March 31, 2013, 1,126,050 ordinary shares were issuable under stock options granted to employees and office holders and an additional 829,800 ordinary shares were available for future grant. On March 23, 2012, we filed a registration statement on Form S-8 registering the ordinary shares that we may issue under our stock incentive plans. Shares included in such registration statement may be freely sold in the public market upon issuance, except for shares held by affiliates who have certain restrictions on their ability to sell.

The 45% interest that we do not own is subject to a put option exercisable by the holder to us. Following the formation of our joint venture in October 2010, we measured all of the assets contributed to Caesarstone Canada Inc. by our former distributor in Eastern Canada, Canadian Quartz Holdings Inc., at their fair value to determine the redeemable non-controlling interest due to the put option granted to Canadian Quartz Holdings Inc. to sell its 45% ownership interest in Caesarstone Canada Inc. to us.

The foregoing table excludes as of December 31, 2012, 2,375,000 ordinary shares reserved for issuance under our 2011 Incentive Compensation Plan of which options to purchase 1,545,200 ordinary shares were outstanding with a weighted average exercise price of $11.13 per share.

Kibbutz Sdot-Yam is a communal society, referred to in Hebrew as a “kibbutz” (plural “kibbutzim”) with approximately 400 members and an additional 350 residents located in Israel on the Mediterranean coast between Tel Aviv and Haifa. Established in 1940, Kibbutz Sdot-Yam is a largely self-governed community of members who share certain social ideals and values on a communal basis. Initially, the social idea behind the formation of the kibbutzim in Israel was to create a communal society in which all members share equally in all of the society’s resources and which provides for the needs of the community. Over the years, the structure of the kibbutzim has evolved, and today there are a number of different economic and social arrangements adopted by various kibbutzim.

Today, all of the members of Kibbutz Sdot-Yam continue to jointly own all of the assets of the Kibbutz. The members of Kibbutz Sdot-Yam are engaged in a number of economic activities, including agriculture, industrial operations and outdoor venue operations. A number of Kibbutz members are engaged in professions outside the Kibbutz. The Kibbutz is the owner and operator of several private companies. The Kibbutz community holds in common all land, buildings and production assets of these companies.

Many members of Kibbutz Sdot-Yam work in one of the production activities of Kibbutz Sdot-Yam, based on the requirements of Kibbutz Sdot-Yam and the career objectives of the individual concerned. Other members work outside of Kibbutz Sdot-Yam in businesses owned by other entities. Each member must deliver to the Kibbutz all his or her income from work, and receives income based on the position the member holds, his or her economic contribution to the community and his or her seniority, as well as on the size and composition of his or her family. Each member’s income depends on the income of Kibbutz Sdot-Yam from its economic activities. Each member has a pension that

Material tax considerations

The following is a general discussion only and is not exhaustive of all possible tax considerations. It is not intended, and should not be construed, as legal or professional tax advice and should not be relied upon for tax planning purposes. In addition, this discussion does not address all of the tax consequences that may be relevant to purchasers of our ordinary shares in light of their particular circumstances, or certain types of purchasers of our ordinary shares subject to special tax treatment. Examples of this kind of investor include residents of Israel and traders in securities who are subject to special tax regimes not covered in this discussion. Each individual/entity should consult its own tax or legal advisor as to the Israeli tax consequences of the purchase, ownership and disposition of our ordinary shares. To the extent that part of the discussion is based on tax legislation, which has not been subject to judicial or administrative interpretation, we cannot assure that the tax authorities or the courts will accept the views expressed in this section.

Israeli tax considerations

The following contains a discussion of the material Israeli tax consequences to holders of our ordinary shares.

Capital gains tax on sales of our ordinary shares

Capital gains tax is imposed on the disposal of capital assets by an Israeli resident and on the disposal of such assets by a non-Israeli resident if those assets are either (i) located in Israel; (ii) shares or rights to shares in an Israeli resident company, or (iii) represent, directly or indirectly, rights to assets located in Israel. The Israeli Income Tax Ordinance distinguishes between “Real Capital Gain” and “Inflationary Surplus.” The Real Capital Gain on the disposition of a capital asset is the amount of total capital gain in excess of Inflationary Surplus. Inflationary Surplus is computed, generally, on the basis of the increase in the Israeli Consumer Price Index between the date of purchase and the date of disposal of the capital asset.

Real Capital Gain generated by a company is generally subject to tax at the corporate tax rate (24% in 2011 and 25% in 2012 and thereafter). As of January 1, 2012, the Real Capital Gain accrued by individuals on the sale of our securities is taxed at the rate of 25%. However, if the individual shareholder is a “Controlling Shareholder” (i.e., a person who holds, directly or indirectly, alone or together with another, 10% or more of one of the Israeli resident company’s “means of control” (including, among other rights, the right to company profits, voting rights, the right to the company’s liquidation proceeds and the right to appoint a company director) at the time of sale or at any time during the preceding 12 month period, such gain will be taxed at the rate of 30%.

Individual and corporate shareholders dealing in securities in Israel are taxed at the tax rates applicable to business income (a tax rate of 24% for a corporation in 2011 and 25% in 2012 and thereafter and a marginal tax rate of up to 45% for an individual in 2011, 48% in 2012 and 50% in 2013). Notwithstanding the foregoing, capital gains generated from the sale of securities by a non-Israeli shareholder may be exempt under the Israeli Income Tax Ordinance from Israeli taxes provided that all the following conditions are met: (i) the securities were purchased upon or after the registration of the securities on a stock exchange (this requirement generally does not apply to shares purchased on or after January 1, 2009), (ii) the seller of the securities does not have a permanent establishment in Israel to which the generated capital gain is attributed and (iii) if the seller is a corporation, less than 25% of its means of control are held, directly and indirectly, by Israeli resident shareholders. In addition, the sale of the securities may be exempt from Israeli capital gain tax under the provisions of an applicable tax treaty. For example, the Convention between the Government of the United States of America and the Government of Israel with respect to Taxes on Income (the “Israel-U.S.A. Double Tax Treaty”) exempts U.S. residents from Israeli capital gains tax in connection with such sale, provided that (i) the U.S. resident owned, directly or indirectly, less than 10% of the Israeli resident company’s voting power at any time within the

TABLE OF CONTENTS

12-month period preceding such sale; (ii) the seller, if an individual, has been present in Israel for less than 183 days (in the aggregate) during the taxable year; and (iii) the capital gain from the sale was not generated through a permanent establishment of the U.S. resident in Israel.

The purchaser of the securities, the stockbrokers who effected the transaction or the financial institution holding the traded securities through which payment to the seller is made are obligated, subject to the above-referenced exemptions, to withhold tax on the Real Capital Gains resulting from a sale of securities at the rate of 25% for a corporation and/or an individual (the withholding tax rate applicable to an individual was 20% in 2011).

A detailed return, including a computation of the tax due, must be filed and an advance payment must be paid on January 31 and June 30 of each tax year for sales of securities traded on a stock exchange made within the previous six months. However, if all tax due was withheld at the source according to applicable provisions of the Israeli Income Tax Ordinance and the regulations promulgated thereunder, the return does not need to be filed and an advance payment does not need to be made. Capital gains are also reportable on an annual income tax return.

Taxation of non-resident shareholders on receipt of dividends

A distribution of a dividend from income attributed to an Approved Enterprise/Beneficiary Enterprise (either to an individual or a corporation) will be subject to tax in Israel at the rate of 15% (4% for a foreign investor under the Ireland Track), subject to a reduced rate under the provisions of any applicable double tax treaty. A distribution of a dividend from income attributed to a Preferred Enterprise to an Israeli corporation will be tax exempt in Israel. Only a distribution of a dividend to an individual or a foreign company will be subject to tax in Israel at a rate of 15% or in accordance with the relevant tax treaty. In addition, subject to certain conditions, Preferred Enterprises can distribute dividends derived from accumulated historic profits attributed to Approved/Beneficiary Enterprises free of tax. A distribution of a dividend from income that is not attributed to an Approved Enterprise/Beneficiary Enterprise/Preferred Enterprise to an Israeli resident individual will generally be subject to income tax at a rate of 25%. However, a 30% tax rate will apply if the dividend recipient is a “Controlling Shareholder” at the time of distribution or at any time during the preceding 12-month period. If the recipient of the dividend is an Israeli resident company, such dividend will be exempt from income tax provided the income from which such dividend is distributed was generated or accrued in Israel.

As of January 1, 2012, the Israeli Income Tax Ordinance provides that a non-Israeli resident (either an individual or a corporation) is generally subject to an Israeli income tax on the receipt of dividends at the rate of 25% (30% if the dividend recipient is a Controlling Shareholder at the time of distribution or at any time during the preceding 12-month period). Such rates may be reduced by the application of the provisions of applicable double tax treaties. Thus, under the Israel-U.S.A. Double Tax Treaty the following rates will apply to dividends distributed by an Israeli resident company to a U.S. resident: (i) if (A) the U.S. resident is a corporation which held during the portion of the taxable year preceding the date of payment of the dividend and during the whole of its prior taxable year (if any), at least 10% of the outstanding shares of the voting stock of the Israeli resident paying company and (B) not more than 25% of the gross income of the Israeli resident paying company for such prior taxable year (if any) consists of certain type of interest or dividends then the tax rate is 12.5%, (ii) if both the conditions mentioned in section (i) above are met and the dividend is paid from the income of an Israeli resident company which was entitled to a reduced tax rate applicable to an Approved Enterprise/Beneficiary Enterprise/Preferred Enterprise then the tax rate is 15%, and (iii) in all other cases, the tax rate is 25%. The aforementioned rates will not apply if the dividend income was generated through a permanent establishment of the U.S. resident in Israel.

Our company is obligated to withhold tax, upon the distribution of a dividend attributed to an Approved Enterprise’s/Beneficiary Enterprise’s/Preferred Enterprise’s income from the amount distributed at the

TABLE OF CONTENTS

following rates: (i) Israeli resident corporations — 0%, (ii) Israeli resident individuals — 15% and (iii) non-Israeli residents — 15% (4% under the Ireland Track), subject to a reduced tax rate under the provisions of an applicable double tax treaty. If the dividend is distributed from income not attributed to the Approved Enterprise/Beneficiary Enterprise/Preferred Enterprise, the following withholding tax rates will apply: (a) for securities registered and held by a clearing corporation: (i) Israeli resident corporations — 0%, (ii) Israeli resident individuals — 25% and (iii) non-Israeli residents — 25%, subject to a reduced tax rate under the provisions of an applicable double tax treaty; (b) in all other cases: (i) Israeli resident corporations — 0%, (ii) Israeli resident individuals — 25%/30% (the 30% tax rate shall apply if the dividend recipient is a “controlling shareholder” (as defined above) at the time of the distribution or at any time during the preceding 12 month period)), and (iii) non-Israeli residents — 25%/30% as referred to above with respect to Israeli resident individuals, subject to a reduced tax rate under the provisions of an applicable double tax treaty.

United States federal income taxation

The following is a description of the material United States federal income tax consequences to a U.S. Holder (as defined below) of the acquisition, ownership and disposition of our ordinary shares. This description addresses only the United States federal income tax consequences to holders that are initial purchasers of our ordinary shares pursuant to the offering and that will hold such ordinary shares as capital assets for United States federal income tax purposes. This description does not address tax considerations applicable to holders that may be subject to special tax rules, including, without limitation:

Moreover, this description does not address the United States federal estate, gift or alternative minimum tax consequences, or any state, local or foreign tax consequences, of the acquisition, ownership and disposition of our ordinary shares.

This description is based on the United States Internal Revenue Code of 1986, as amended (the “Code”), existing, proposed and temporary United States Treasury Regulations and judicial and administrative interpretations thereof, in each case as in effect and available on the date hereof. All of the foregoing are subject to change, which change could apply retroactively and could affect the tax consequences

TABLE OF CONTENTS

described below. There can be no assurances that the U.S. Internal Revenue Service will not take a different position concerning the tax consequences of the acquisition, ownership and disposition of our ordinary shares or that such a position could not be sustained.

For purposes of this description, a “U.S. Holder” is a beneficial owner of our ordinary shares that, for United States federal income tax purposes, is:

If a partnership (or any other entity treated as a partnership for United States federal income tax purposes) holds our ordinary shares, the tax treatment of a partner in such partnership will generally depend on the status of the partner and the activities of the partnership. Such a partner or partnership should consult its tax advisor as to its tax consequences.

You should consult your tax advisor with respect to the United States federal, state, local and foreign tax consequences of acquiring, owning and disposing of our ordinary shares.

Distributions

Subject to the discussion below under “Passive foreign investment company considerations,” if you are a U.S. Holder, the gross amount of any distribution made to you with respect to our ordinary shares before reduction for any Israeli taxes withheld therefrom, other than pro rata distributions of our ordinary shares to all our shareholders, generally will be includible in your income as dividend income to the extent such distribution is paid out of our current or accumulated earnings and profits as determined under United States federal income tax principles. Subject to the discussion below under “Passive foreign investment company considerations,” non-corporate U.S. Holders may qualify for the lower rates of taxation with respect to dividends on ordinary shares applicable to long-term capital gains (i.e., gains from the sale of capital assets held for more than one year) provided that certain conditions are met, including certain holding period requirements and the absence of certain risk reduction transactions. However, such dividends will not be eligible for the dividends received deduction generally allowed to corporate U.S. Holders. Subject to the discussion below under “Passive foreign investment company considerations,” to the extent that the amount of any distribution by us exceeds our current and accumulated earnings and profits as determined under United States federal income tax principles, it will be treated first as a tax-free return of your adjusted tax basis in our ordinary shares and thereafter as capital gain. We do not expect to maintain calculations of our earnings and profits under United States federal income tax principles and, therefore, U.S. Holders should expect that the entire amount of any distribution generally will be reported as dividend income.

Dividends paid to U.S. Holders with respect to our ordinary shares will be treated as foreign source income, which may be relevant in calculating your foreign tax credit limitation. Subject to certain conditions and limitations, Israeli tax withheld on dividends may be deducted from your taxable income or credited against your United States federal income tax liability. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For this purpose, dividends

TABLE OF CONTENTS

that we distribute generally should constitute “passive category income,” or, in the case of certain U.S. Holders, “general category income.” A foreign tax credit for foreign taxes imposed on distributions may be denied if you do not satisfy certain minimum holding period requirements. The rules relating to the determination of the foreign tax credit are complex, and you should consult your tax advisor to determine whether and to what extent you will be entitled to this credit.

We have not yet determined whether future distributions with respect to our ordinary shares will be paid in U.S. dollars or NIS. If a distribution is denominated in NIS, the amount of such distribution will equal the U.S. dollar value of the NIS received, calculated by reference to the exchange rate in effect on the date that distribution is received, whether or not the U.S. Holder in fact converts any NIS received into U.S. dollars at that time. If the distribution is converted into U.S. dollars on the date of receipt, a U.S. Holder generally will not be required to recognize foreign currency gain or loss in respect of the distribution. A U.S. Holder may have foreign currency gain or loss if the distribution is converted into U.S. dollars after the date of receipt. Any gains or losses resulting from the conversion of NIS into U.S. dollars will be treated as ordinary income or loss, as the case may be, of the U.S. Holder and will be U.S.-source.

Sale, exchange or other disposition of ordinary shares

Subject to the discussion below under “Passive foreign investment company considerations,” U.S. Holders generally will recognize gain or loss on the sale, exchange or other disposition of our ordinary shares equal to the difference between the amount realized on such sale, exchange or other disposition and such holder’s adjusted tax basis in our ordinary shares, and such gain or loss will be capital gain or loss. The adjusted tax basis in an ordinary share generally will be equal to the cost of such ordinary share. If you are a non-corporate U.S. Holder, capital gain from the sale, exchange or other disposition of ordinary shares is generally eligible for a preferential rate of taxation applicable to capital gains, if your holding period for such ordinary shares exceeds one year (i.e., such gain is long-term capital gain). The deductibility of capital losses for United States federal income tax purposes is subject to limitations under the Code. Any such gain or loss that a U.S. Holder recognizes generally will be treated as U.S. source income or loss for foreign tax credit limitation purposes.

Passive foreign investment company considerations

If we were to be classified as a “passive foreign investment company,” or PFIC, in any taxable year, a U.S. Holder would be subject to special rules generally intended to reduce or eliminate any benefits from the deferral of United States federal income tax that a U.S. Holder could derive from investing in a non-U.S. company that does not distribute all of its earnings on a current basis.

A non-U.S. corporation will be classified as a PFIC for United States federal income tax purposes in any taxable year in which, after applying certain look-through rules, either:

Passive income for this purpose generally includes dividends, interest, royalties, rents, gains from commodities and securities transactions, the excess of gains over losses from the disposition of assets which produce passive income, and includes amounts derived by reason of the temporary investment of funds raised in offerings of our ordinary shares. If a non-U.S. corporation owns at least 25% by value of the stock of another corporation, the non-U.S. corporation is treated for purposes of the PFIC tests as owning its proportionate share of the assets of the other corporation and as receiving directly its proportionate share of the other corporation’s income. If we are classified as a PFIC in any year with respect to which a U.S. Holder owns our ordinary shares, we will continue to be treated as a PFIC with respect to such U.S. Holder in all succeeding years during which the U.S. Holder owns our ordinary shares, regardless of whether we continue to meet the tests described above.

TABLE OF CONTENTS

Based on our most current estimates of our gross income and gross assets and the nature of our business, we do not believe we were a PFIC for the taxable year ended December 31, 2012 and do not expect that we will be classified as a PFIC for the taxable year ending December 31, 2013. However, because PFIC status is based on our income, assets and activities for the entire taxable year, it is not possible to determine whether we will be characterized as a PFIC for the 2013 taxable year until after the close of the taxable year. Moreover, we must determine our PFIC status annually based on tests which are factual in nature, and our status in future years will depend on our income, assets and activities in those years. There can be no assurance that we will not be considered a PFIC for any taxable year. If we were a PFIC, then, unless you make one of the elections described below, a special tax regime will apply to both (a) any “excess distribution” by us to you (generally, your ratable portion of distributions in any year which are greater than 125% of the average annual distribution received by you in the shorter of the three preceding years or your holding period for our ordinary shares) and (b) any gain realized on the sale or other disposition of the ordinary shares.

Under this regime, any excess distribution and realized gain will be treated as ordinary income and will be subject to tax as if (a) the excess distribution or gain had been realized ratably over your holding period, (b) the amount deemed realized in each year had been subject to tax in each year of that holding period at the highest marginal rate for such year (other than income allocated to the current period or any taxable period before we became a PFIC, which will be subject to tax at the U.S. Holder’s regular ordinary income rate for the current year and will not be subject to the interest charge discussed below), and (c) the interest charge generally applicable to underpayments of tax had been imposed on the taxes deemed to have been payable in those years. In addition, dividend distributions made to you will not qualify for the lower rates of taxation applicable to long-term capital gains discussed above under “Distributions.” Certain elections may be available that would result in an alternative treatment (such as mark-to-market treatment) of our ordinary shares. We do not intend to provide the information necessary for U.S. Holders to make qualified electing fund elections if we are classified as a PFIC. U.S. Holders should consult their tax advisors to determine whether any of these elections would be available and if so, what the consequences of the alternative treatments would be in their particular circumstances.

If we are determined to be a PFIC, the general tax treatment for U.S. Holders described in this paragraph would apply to indirect distributions and gains deemed to be realized by U.S. Holders in respect of any of our subsidiaries that also may be determined to be PFICs.

If a U.S. Holder owns ordinary shares during any year in which we are classified as a PFIC and the U.S. Holder recognizes gain on a disposition of our ordinary shares or receives distributions with respect to our ordinary shares, the U.S. Holder generally will be required to file an IRS Form 8621 with respect to the company, generally with the U.S. Holder’s federal income tax return for that year. Additionally, recently enacted legislation creates an additional annual filing requirement for U.S. persons who are shareholders of a PFIC. The legislation does not describe what information will be required to be included in the additional annual filing, but rather grants the Secretary of the U.S. Treasury authority to decide what information must be included in such annual filing. If our company were a PFIC for a given taxable year, then you should consult your tax advisor concerning your annual filing requirements.

U.S. Holders should consult their tax advisors regarding whether we are a PFIC and the potential application of the PFIC rules.

Backup withholding tax and information reporting requirements

United States backup withholding tax and information reporting requirements may apply to certain payments to certain holders of stock. Information reporting generally will apply to payments of dividends on, and to proceeds from the sale or redemption of, our ordinary shares made within the United States, or by a U.S. payor or U.S. middleman, to a holder of our ordinary shares, other than an exempt recipient (including a payee that is not a United States person that provides an appropriate certification and certain other persons). A payor will be required to withhold backup withholding tax from any payments of

TABLE OF CONTENTS

dividends on, or the proceeds from the sale or redemption of, ordinary shares within the United States, or by a U.S. payor or U.S. middleman, to a holder, other than an exempt recipient, if such holder fails to furnish its correct taxpayer identification number or otherwise fails to comply with, or establish an exemption from, such backup withholding tax requirements. Any amounts withheld under the backup withholding rules will be allowed as a credit against the beneficial owner’s United States federal income tax liability, if any, and any excess amounts withheld under the backup withholding rules may be refunded, provided that the required information is timely furnished to the U.S. Internal Revenue Service.

3.8% Medicare tax on “net investment income”

Certain U.S. Holders who are individuals, estates or trusts are required to pay an additional 3.8% tax on, among other things, dividends and capital gains from the sale or other disposition of shares of common stock.

Foreign asset reporting

Certain U.S. Holders who are individuals are required to report information relating to an interest in our ordinary shares, subject to certain exceptions (including an exception for shares held in accounts maintained by U.S. financial institutions). U.S. Holders are urged to consult their tax advisors regarding their information reporting obligations, if any, with respect to their ownership and disposition of our ordinary shares.

The above description is not intended to constitute a complete analysis of all tax consequences relating to the acquisition, ownership and disposition of our ordinary shares. You should consult your tax advisor concerning the tax consequences of your particular situation.

Underwriting

The selling shareholders are offering the ordinary shares described in this prospectus supplement through a number of underwriters. J.P. Morgan Securities LLC, Barclays Capital Inc. and Credit Suisse Securities (USA), LLC are acting as joint book-running managers of the offering and as representatives of the underwriters. We and the selling shareholders have entered into an underwriting agreement with the underwriters. Subject to the terms and conditions of the underwriting agreement, the selling shareholders have agreed to sell to the underwriters, and each underwriter has severally agreed to purchase, at the public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus supplement, the number of ordinary shares listed next to its name in the following table:

Name		Number of Ordinary Shares
J.P. Morgan Securities LLC
Barclays Capital Inc.
Credit Suisse Securities (USA) LLC
Stifel, Nicolaus & Company, Incorporated
Robert W. Baird & Co. Incorporated
Total			7,250,000

The underwriters are committed to purchase all the ordinary shares offered by the selling shareholders if they purchase any shares. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated.

The underwriters propose to offer the ordinary shares directly to the public at the initial public offering price set forth on the cover page of this prospectus supplement and to certain dealers at that price less a concession not in excess of $     per ordinary share. Any such dealers may resell ordinary shares to certain other brokers or dealers at a discount of up to $     per ordinary share from the initial public offering price. After the initial public offering of the shares, the offering price and other selling terms may be changed by the underwriters. Sales of shares made outside of the United States may be made by affiliates of the underwriters.

The underwriters have an option to buy up to 1,087,500 additional ordinary shares from the selling shareholders. The underwriters have 30 days from the date of this prospectus supplement to exercise this option. If any ordinary shares are purchased pursuant to this option, the underwriters will purchase such shares in approximately the same proportion as shown in the table above. If any additional ordinary shares are purchased, the underwriters will offer the additional shares on the same terms as those on which the shares are being offered.

The underwriting fee is equal to the public offering price per ordinary share less the amount paid by the underwriters to the selling shareholders per ordinary share. The underwriting fee is $     per share. The following table shows the per ordinary share and total underwriting discounts and commissions to be paid to the underwriters assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares.

We estimate that the total expenses of this offering payable by us will be approximately $0.5 million, which includes an amount not to exceed $10,000 that we have agreed to reimburse the underwriters for certain expenses incurred by them in connection with this offering.

A prospectus supplement in electronic format may be made available on the web sites maintained by one or more underwriters, or selling group members, if any, participating in the offering. The underwriters may agree to allocate a number of ordinary shares to underwriters and selling group members for sale to their online brokerage account holders. Internet distributions will be allocated by the representatives to underwriters and selling group members that may make Internet distributions on the same basis as other allocations.

We have agreed that we will not (i) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise dispose of, directly or indirectly, or file with the Securities and Exchange Commission a registration statement under the Securities Act relating to, any of our ordinary shares or securities convertible into or exchangeable or exercisable for any of our ordinary shares, or publicly disclose the intention to make any offer, sale, pledge, disposition or filing, or (ii) enter into any swap or other arrangement that transfers all or a portion of the economic consequences associated with the ownership of any ordinary shares or any such other securities (regardless of whether any of these transactions are to be settled by the delivery of ordinary shares or such other securities, in cash or otherwise), in each case without the prior written consent of J.P. Morgan Securities LLC and Barclays Capital Inc. for a period of 90 days after the date of this prospectus supplement, other than the ordinary shares to be sold in this offering and any ordinary shares issued upon the exercise of options granted under our existing equity incentive plans.

Our directors and officers and the selling shareholders have entered into lock-up agreements with the underwriters prior to the commencement of this offering pursuant to which each of these persons or entities for a period of 90 days after the date of this prospectus supplement, may not, without the prior written consent of J.P. Morgan Securities LLC and Barclays Capital Inc., (1) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any of our ordinary shares or any securities convertible into or exercisable or exchangeable for our ordinary shares (including, without limitation, ordinary shares or such other securities which may be deemed to be beneficially owned by such persons or entities in accordance with the rules and regulations of the SEC and securities which may be issued upon exercise of a stock option or warrant) or (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the ordinary shares or such other securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of ordinary shares or such other securities, in cash or otherwise, or (3) make any demand for or exercise any right with respect to the registration of any of our ordinary shares or any security convertible into or exercisable or exchangeable for our ordinary shares.

The restrictions described in the immediately preceding paragraph do not apply to, among other things, the sale of up to an aggregate of 245,975 ordinary shares by our officers commencing 30 days after the date of this prospectus supplement.

We and the selling shareholders have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933.

TABLE OF CONTENTS

In connection with this offering, the underwriters may engage in stabilizing transactions, which involve making bids for, purchasing and selling ordinary shares in the open market for the purpose of preventing or retarding a decline in the market price of the ordinary shares while this offering is in progress. These stabilizing transactions may include making short sales of the ordinary shares, which involves the sale by the underwriters of a greater number of ordinary shares than they are required to purchase in this offering, and purchasing ordinary shares on the open market to cover positions created by short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ option to purchase additional shares referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriters may close out any covered short position either by exercising their option, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriters will consider, among other things, the price of shares available for purchase in the open market compared to the price at which the underwriters may purchase shares through their option. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the ordinary shares in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriters create a naked short position, they will purchase shares in the open market to cover the position.

The underwriters have advised us that, pursuant to Regulation M of the Securities Act of 1933, they may also engage in other activities that stabilize, maintain or otherwise affect the price of the ordinary shares, including the imposition of penalty bids. This means that if the representatives of the underwriters purchase ordinary shares in the open market in stabilizing transactions or to cover short sales, the representatives can require the underwriters that sold those shares as part of this offering to repay the underwriting discount received by them.

These activities may have the effect of raising or maintaining the market price of the ordinary shares or preventing or retarding a decline in the market price of the ordinary shares, and, as a result, the price of the ordinary shares may be higher than the price that otherwise might exist in the open market. If the underwriters commence these activities, they may discontinue them at any time. The underwriters may carry out these transactions on the Nasdaq Global Select Market, in the over-the-counter market or otherwise.

In addition, in connection with this offering certain of the underwriters (and selling group members) may engage in passive market making transactions in our ordinary shares on The Nasdaq Stock Market prior to the pricing and completion of this offering. Passive market making consists of displaying bids on The Nasdaq Stock Market no higher than the bid prices of independent market makers and making purchases at prices no higher than these independent bids and effected in response to order flow. Net purchases by a passive market maker on each day are generally limited to a specified percentage of the passive market maker’s average daily trading volume in the ordinary shares during a specified period and must be discontinued when such limit is reached. Passive market making may cause the price of our ordinary shares to be higher than the price that otherwise would exist in the open market in the absence of these transactions. If passive market making is commenced, it may be discontinued at any time.

Certain of the underwriters and their affiliates have provided in the past to us and our affiliates and may provide from time to time in the future certain commercial banking, financial advisory, investment banking and other services for us and such affiliates in the ordinary course of their business, for which they have received and may continue to receive customary fees and commissions. In addition, from time to time, certain of the underwriters and their affiliates may effect transactions for their own account or the account of customers, and hold on behalf of themselves or their customers, long or short positions in our debt or equity securities or loans, and may do so in the future.

Other than in the United States, no action has been taken by us or the underwriters that would permit a public offering of the securities offered by this prospectus supplement in any jurisdiction where action for that purpose is required. The securities offered by this prospectus supplement may not be offered or sold, directly or indirectly, nor may this prospectus supplement or any other offering material or advertisements

Enforceability of civil liabilities

We are incorporated under the laws of the State of Israel. Service of process upon us and upon our directors and officers and the Israeli experts named in this prospectus, substantially all of whom reside outside the United States, may be difficult to obtain within the United States. Furthermore, because substantially all of our assets and substantially all of our directors and officers are located outside the United States, any judgment obtained in the United States against us or any of our directors and officers may not be collectible within the United States.

We have irrevocably appointed Caesarstone USA, Inc. as our agent to receive service of process in any action against us in any United States federal or state court arising out of this offering or any purchase or sale of securities in connection with this offering. The address of Caesarstone USA, Inc. is 6840 Hayvenhurst Ave. Suite 100, Van Nuys, California 91406.

We have been informed by our legal counsel in Israel, Gross, Kleinhendler, Hodak, Halevy, Greenberg & Co., that it may be difficult to initiate an action with respect to United States securities law in Israel. Israeli courts may refuse to hear a claim based on an alleged violation of United States securities laws reasoning that Israel is not the most appropriate forum to hear such a claim. In addition, even if an Israeli court agrees to hear a claim, it may determine that Israeli law and not United States law is applicable to the claim. If United States law is found to be applicable, the content of applicable U.S. law must be proved as a fact by expert witnesses which can be a time-consuming and costly process. Certain matters of procedure may also be governed by Israeli law.

Subject to certain time limitations and legal procedures, Israeli courts may enforce a United States judgment in a civil matter which, subject to certain exceptions, is non-appealable, including judgments

TABLE OF CONTENTS

based upon the civil liability provisions of the Securities Act and the Exchange Act and including a monetary or compensatory judgment in a non-civil matter, provided that:

Even if these conditions are met, an Israeli court will not declare a foreign civil judgment enforceable if:

If a foreign judgment is enforced by an Israeli court, it generally will be payable in Israeli currency, which can then be converted into non-Israeli currency and transferred out of Israel. The usual practice in an action before an Israeli court to recover an amount in a non-Israeli currency is for the Israeli court to issue a judgment for the equivalent amount in Israeli currency at the rate of exchange in force on the date of the judgment, but the judgment debtor may make payment in foreign currency. Pending collection, the amount of the judgment of an Israeli court stated in Israeli currency ordinarily will be linked to the Israeli consumer price index plus interest at the annual statutory rate set by Israeli regulations prevailing at the time. Judgment creditors must bear the risk of unfavorable exchange rates.

DESCRIPTION OF ORDINARY SHARES

Our authorized share capital consists of 200,000,000 ordinary shares, par value NIS 0.04 per share, of which 34,487,385 were issued and outstanding as of February 28, 2013.

Our ordinary shares are not redeemable and do not have preemptive rights. The ownership or voting of ordinary shares by non-residents of Israel is not restricted in any way by our articles of association or the laws of the State of Israel, except for anti-terror legislation and except that citizens of countries which are in a state of war with Israel may not be recognized as owners of ordinary shares.

The description below is a summary of the material provisions of our articles of association and of the Israeli Companies Law, 5759-1999 (the “Companies Law”).

Voting

Holders of our ordinary shares have one vote for each ordinary share held on all matters submitted to a vote of shareholders at a shareholder meeting. Shareholders may vote at shareholder meetings either in person, by proxy or, with respect to certain resolutions, by a voting instrument.

TABLE OF CONTENTS

Israeli law does not allow public companies to adopt shareholder resolutions by means of written consent in lieu of a shareholder meeting. Shareholder voting rights may be affected by the grant of any special voting rights to the holders of a class of shares with preferential rights that may be authorized in the future.

In addition, pursuant to a voting agreement, Kibbutz Sdot-Yam and Tene have agreed to the following:

This voting arrangement between Kibbutz Sdot-Yam and Tene will terminate if Tene’s holdings in our company decrease below 8.25%. Tene will notify Kibbutz Sdot-Yam no later than seven days following the occurrence of such an event.

Transfer of shares

Fully paid ordinary shares are issued in registered form and may be freely transferred under our articles of association unless the transfer is restricted or prohibited by another instrument, Israeli law or the rules of a stock exchange on which the shares are traded.

Election of directors

Our ordinary shares do not have cumulative voting rights for the election of directors. Rather, under our articles of association our directors are elected by the holders of a simple majority of our ordinary shares at a general shareholder meeting (excluding abstentions). As a result, the holders of our ordinary shares that represent more than 50% of the voting power represented at a shareholder meeting and voting thereon (excluding abstentions) have the power to elect any or all of our directors whose positions are being filled at that meeting, provided that either:

See “— Voting” for a description of the voting agreement between Kibbutz Sdot-Yam and Tene Investment Funds.

Dividend and liquidation rights

Under Israeli law, we may declare and pay dividends only if, upon the determination of our board of directors, there is no reasonable concern that the distribution will not prevent us from being able to meet the terms of our existing and foreseeable obligations as they become due. Under the Companies Law, the distribution amount is further limited to the greater of retained earnings or earnings generated over the two most recent years legally available for distribution. In the event that we do not have retained earnings or

TABLE OF CONTENTS

earnings generated over the two most recent years legally available for distribution, we may seek the approval of the court in order to distribute a dividend. The court may approve our request if it is convinced that there is no reasonable concern that the payment of a dividend will prevent us from satisfying our existing and foreseeable obligations as they become due.

In the event of our liquidation, after satisfaction of liabilities to creditors, our assets will be distributed to the holders of ordinary shares on a pro-rata basis. Dividend and liquidation rights may be affected by the grant of preferential dividend or distribution rights to the holders of a class of shares with preferential rights that may be authorized in the future.

Shareholder meetings

We are required to convene an annual general meeting of our shareholders once every calendar year within a period of not more than 15 months following the preceding annual general meeting. Our board of directors may convene a special general meeting of our shareholders and is required to do so at the request of two directors or one quarter of the members of our board of directors, or at the request of one or more holders of 5% or more of our share capital and 1% of our voting power, or the holder or holders of 5% or more of our voting power. All shareholder meetings require prior notice of at least 14 days and, in certain cases, 35 days. The chairman of our board of directors presides over our general meetings. However, if there is no such chairman or if at any meeting the chairman is not present within 15 minutes after the appointed time, or is unwilling to act as chairman, then the board members present at the meeting shall choose one of the board members as chairman of the meeting and if they shall not do so then the shareholders present shall choose a board member, or if no board member is present or if all the board members present decline to take the chair, they shall choose any other person present to be chairman of the meeting. Subject to the provisions of the Companies Law and the regulations promulgated thereunder, shareholders entitled to participate and vote at general meetings are the shareholders of record on a date to be decided by the board of directors, which may be between four and 40 days prior to the date of the meeting, depending on the type of meeting and whether written proxies are being used.

Quorum

Pursuant to our articles of association, the quorum required for a meeting of shareholders consists of at least two shareholders present in person, by proxy or by a voting instrument, who hold at least 25% of our voting power. A meeting adjourned for lack of a quorum generally is adjourned one week thereafter at the same time and place, or to such other day, time and place, as our board of directors may indicate in the invitation to the meeting or in the notice of the meeting to the shareholders. At an adjourned meeting, any number of shareholders constitutes a quorum.

Resolutions

Under the Companies Law, unless otherwise provided in the articles of association or applicable law, all resolutions of the shareholders require a simple majority of the voting rights represented at the meeting, in person, by proxy or, with respect to certain resolutions, by a voting instrument, and voting on the resolution (excluding abstentions). A resolution for the voluntary winding up of the company requires the approval by the holders of 75% of the voting rights represented at the meeting, in person, by proxy and voting on the resolution (excluding abstentions).

Access to corporate records

Under the Companies Law, all shareholders generally have the right to review minutes of our general meetings, our shareholder register and register of significant shareholders (as defined in the Companies Law), our articles of association, our financial statements, other documents as provided in the Companies Law, and any document we are required by law to file publicly with the Israeli Companies Registrar or with the Israel Securities Authority. Any shareholder who specifies the purpose of its request may request to review any document in our possession that relates to any action or transaction with a related party or an action in which an office holder has a personal interest that requires shareholder approval under the Companies Law. We may deny a request to review a document if we determine that the request was not made in good faith, that the document contains a commercial secret or a patent or that the document’s disclosure may otherwise impair our interests.

TABLE OF CONTENTS

Acquisitions under Israeli law

Full tender offer

A person wishing to acquire shares of an Israeli public company and who would as a result hold over 90% of the target company’s issued and outstanding share capital is required by the Companies Law to make a tender offer to all of the company’s shareholders for the purchase of all of the issued and outstanding shares of the company.

A person wishing to acquire shares of an Israeli public company and who would as a result hold over 90% of the issued and outstanding share capital of a certain class of shares is required to make a tender offer to all of the shareholders who hold shares of the same class for the purchase of all of the issued and outstanding shares of the same class.

If the shareholders who do not respond to or accept the offer hold less than 5% of the issued and outstanding share capital of the company or of the applicable class of the shares, and more than half of the shareholders who do not have a personal interest in the offer accept the offer, all of the shares that the acquirer offered to purchase will be transferred to the acquirer by operation of law. However, a tender offer will be accepted if the shareholders who do not accept it hold less than 2% of the issued and outstanding share capital of the company or of the applicable class of the shares.

Upon a successful completion of such a full tender offer, any shareholder that was an offeree in such tender offer, whether such shareholder accepted the tender offer or not, may, within six months from the date of acceptance of the tender offer, petition the Israeli court to determine whether the tender offer was for less than fair value and that the fair value should be paid as determined by the court. However, under certain conditions, the offeror may determine in the terms of the tender offer that an offeree who accepted the offer will not be entitled to petition the Israeli court as described above.

If the shareholders who did not respond or accept the tender offer hold at least 5% of the issued and outstanding share capital of the company or of the applicable class, the acquirer may not acquire shares of the company that will increase its holdings to more than 90% of the company’s issued and outstanding share capital or of the applicable class from shareholders who accepted the tender offer.

The description above regarding a full tender offer shall also apply, with necessary changes, when a full tender offer is accepted and the offeror has also offered to acquire all of the company’s securities.

Special tender offer

The Companies Law provides that an acquisition of shares of an Israeli public company must be made by means of a special tender offer if as a result of the acquisition the purchaser would become a holder of at least 25% of the voting rights in the company. This rule does not apply if there is already another holder of at least 25% of the voting rights in the company.

Similarly, the Companies Law provides that an acquisition of shares in a public company must be made by means of a special tender offer if as a result of the acquisition the purchaser would become a holder of more than 45% of the voting rights in the company, if there is no other shareholder of the company who holds more than 45% of the voting rights in the company.

These requirements do not apply if the acquisition (i) occurs in the context of a private offering, on the condition that the shareholders meeting approved the acquisition as a private offering whose purpose is to give the acquirer at least 25% of the voting rights in the company if there is no person who holds at least 25% of the voting rights in the company, or as a private offering whose purpose is to give the acquirer 45% of the voting rights in the company, if there is no person who holds 45% of the voting rights in the company; (ii) was from a shareholder holding at least 25% of the voting rights in the company and resulted in the acquirer becoming a holder of at least 25% of the voting rights in the company or (iii) was from a holder of more than 45% of the voting rights in the company and resulted in the acquirer becoming a holder of more than 45% of the voting rights in the company.

The special tender offer may be consummated only if (i) at least 5% of the voting power attached to the company’s outstanding shares will be acquired by the offeror and (ii) the special tender offer is accepted by a

TABLE OF CONTENTS

majority of the votes of those offerees who gave notice of their position in respect of the offer; in counting the votes of offerees, the votes of a holder of control in the offeror, a person who has personal interest in acceptance of the special tender offer, a holder of at least 25% of the voting rights in the company, or any person acting on their or on the offeror’s behalf, including their relatives or companies under their control, are not taken into account. In the event that a special tender offer is made, a company’s board of directors is required to express its opinion on the advisability of the offer or shall abstain from expressing any opinion if it is unable to do so, provided that it gives the reasons for its abstention.

An office holder in a target company who, in his or her capacity as an office holder, performs an action the purpose of which is to cause the failure of an existing or foreseeable special tender offer or is to impair the chances of its acceptance, is liable to the potential purchaser and shareholders for damages resulting from his acts, unless such office holder acted in good faith and had reasonable grounds to believe he or she was acting for the benefit of the company. However, office holders of the target company may negotiate with the potential purchaser in order to improve the terms of the special tender offer, and may further negotiate with third parties in order to obtain a competing offer.

If a special tender offer was accepted by a majority of the shareholders who announced their stand on such offer, then shareholders who did not respond to the special offer or had objected to the special tender offer may accept the offer within four days of the last day set for the acceptance of the offer.

In the event that a special tender offer is accepted, then the purchaser or any person or entity controlling it and any corporation controlled by them shall refrain from making a subsequent tender offer for the purchase of shares of the target company and may not execute a merger with the target company for a period of one year from the date of the offer, unless the purchaser or such person or entity undertook to effect such an offer or merger in the initial special tender offer.

Merger

The Companies Law permits merger transactions if approved by each party’s board of directors and, unless certain requirements described under the Companies Law are met, a majority of each party’s shareholders, by a majority of each party’s shares that are voted on the proposed merger at a shareholders’ meeting.

The board of directors of a merging company is required pursuant to the Companies Law to discuss and determine whether in its opinion there exists a reasonable concern that as a result of a proposed merger, the surviving company will not be able to satisfy its obligations towards its creditors, taking into account the financial condition of the merging companies. If the board of directors has determined that such a concern exists, it may not approve a proposed merger. Following the approval of the board of directors of each of the merging companies, the boards of directors must jointly prepare a merger proposal for submission to the Israeli Registrar of Companies.

For purposes of the shareholder vote, unless a court rules otherwise, the merger will not be deemed approved if a majority of the shares voting at the shareholders meeting (excluding abstentions) that are held by parties other than the other party to the merger, any person who holds 25% or more of the means of control of the other party to the merger or any one on their behalf including their relatives or corporations controlled by any of them, vote against the merger. In addition, if the non-surviving entity of the merger has more than one class of shares, the merger must be approved by each class of shareholders.

The term “means of control” is defined as (1) the right to vote at a general meeting of a company or a corresponding body of another corporation; or (2) the right to appoint directors of the corporation.

The term “relative” is defined as a spouse, sibling, parent, grandparent, descendant, spouse’s descendant, sibling and parent and the spouse of each of the foregoing.

If the transaction would have been approved but for the separate approval of each class of shares or the exclusion of the votes of certain shareholders as provided above, a court may still rule that the company has approved the merger upon the request of holders of at least 25% of the voting rights of a company, if the court holds that the merger is fair and reasonable, taking into account the appraisal of the merging companies’ value and the consideration offered to the shareholders.

TABLE OF CONTENTS

Under the Companies Law, each merging company must send a copy of the proposed merger plan to its secured creditors. Unsecured creditors are entitled to receive notice of the merger, as provided by the regulations promulgated under the Companies Law. Upon the request of a creditor of either party to the proposed merger, the court may delay or prevent the merger if it concludes that there exists a reasonable concern that, as a result of the merger, the surviving company will be unable to satisfy the obligations of the target company. The court may also give instructions in order to secure the rights of creditors.

In addition, a merger may not be completed unless at least 50 days have passed from the date that a proposal for approval of the merger was filed with the Israeli Registrar of Companies and 30 days from the date that shareholder approval of both merging companies was obtained.

Anti-takeover measures

The Companies Law allows us to create and issue shares having rights different from those attached to our ordinary shares, including shares providing certain preferred or additional rights to voting, distributions or other matters and shares having preemptive rights. We do not have any authorized or issued shares other than ordinary shares. In the future, if we do create and issue a class of shares other than ordinary shares, such class of shares, depending on the specific rights that may be attached to them, may delay or prevent a takeover or otherwise prevent our shareholders from realizing a potential premium over the market value of their ordinary shares. The authorization of a new class of shares will require an amendment to our articles of association which requires the prior approval of a majority of our shares represented and voting at a general meeting. Shareholders voting at such a meeting will be subject to the restrictions under the Companies Law described in “— Voting.”

Changes in capital

Our articles of association enable us to increase or reduce our share capital. Any such changes are subject to the provisions of the Companies Law and must be approved by a resolution duly passed by our shareholders at a general or special meeting by voting on such change.

PLAN OF DISTRIBUTION

The securities being offered by this prospectus may be sold:

TABLE OF CONTENTS

At any time a particular offer of the securities covered by this prospectus is made, a revised prospectus or prospectus supplement, if required, will be distributed which will set forth the aggregate amount of securities covered by this prospectus being offered and the terms of the offering, including the name or names of any underwriters, dealers, brokers or agents, any discounts, commissions, concessions and other items constituting compensation from us and any discounts, commissions or concessions allowed or reallowed or paid to dealers. Such prospectus supplement, and, if necessary, a post-effective amendment to the registration statement of which this prospectus is a part, will be filed with the SEC to reflect the disclosure of additional information with respect to the distribution of the securities covered by this prospectus. In order to comply with the securities laws of certain states, if applicable, the securities sold under this prospectus may only be sold through registered or licensed broker-dealers. In addition, in some states the securities may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from registration or qualification requirements is available and is complied with.

Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

The distribution of securities may be effected from time to time in one or more transactions, including block transactions and transactions on the Nasdaq Global Select Market or any other organized market where the securities may be traded. The securities may be sold at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to the prevailing market prices or at negotiated prices. The consideration may be cash or another form negotiated by the parties. Agents, underwriters or broker-dealers may be paid compensation for offering and selling the securities. That compensation may be in the form of discounts, concessions or commissions to be received from the selling shareholders or the purchasers of the securities. Any dealers and agents participating in the distribution of the securities may be deemed to be underwriters, and compensation received by them on resale of the securities may be deemed to be underwriting discounts. If any such dealers or agents were deemed to be underwriters, they may be subject to statutory liabilities under the Securities Act.

Agents may from time to time solicit offers to purchase the securities. If required, we will name in the applicable prospectus supplement any agent involved in the offer or sale of the securities and set forth any compensation payable to the agent. Unless otherwise indicated in the prospectus supplement, any agent will be acting on a best efforts basis for the period of its appointment. Any agent selling the securities covered by this prospectus may be deemed to be an underwriter, as that term is defined in the Securities Act, of the securities.

If underwriters are used in a sale, securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale, or other contractual commitments. Securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. If an underwriter or underwriters are used in the sale of securities, an underwriting agreement will be executed with the underwriter or underwriters, as well as any other underwriter or underwriters, with respect to a particular underwritten offering of securities, and will set forth the terms of the transactions, including compensation of the underwriters and dealers and the public offering price, if applicable. The prospectus and prospectus supplement will be used by the underwriters to resell the securities.

If a dealer is used in the sale of the securities, the selling shareholders or an underwriter will sell the securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale. To the extent required, we will set forth in the prospectus supplement the name of the dealer and the terms of the transactions.

The selling shareholders may directly solicit offers to purchase the securities and may make sales of securities directly to institutional investors or others. These persons may be deemed to be underwriters within the meaning of the Securities Act with respect to any resale of the securities. To the extent required, the prospectus supplement will describe the terms of any such sales, including the terms of any bidding or auction process, if used.

TABLE OF CONTENTS

Agents, underwriters and dealers may be entitled under agreements which may be entered into with us or the selling shareholders to indemnification by us and the selling shareholders against specified liabilities, including liabilities incurred under the Securities Act, or to contribution by us or the selling shareholders to payments they may be required to make in respect of such liabilities. If required, the prospectus supplement will describe the terms and conditions of the indemnification or contribution. Some of the agents, underwriters or dealers, or their affiliates may be customers of, engage in transactions with or perform services for us or our subsidiaries.

Any person participating in the distribution of securities registered under the registration statement that includes this prospectus will be subject to applicable provisions of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and the applicable SEC rules and regulations, including, among others, Regulation M, which may limit the timing of purchases and sales of any of our securities by that person. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of our securities to engage in market-making activities with respect to our securities. These restrictions may affect the marketability of our securities and the ability of any person or entity to engage in market-making activities with respect to our securities.

Certain persons participating in an offering may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids that stabilize, maintain or otherwise affect the price of the offered securities. These activities may maintain the price of the offered securities at levels above those that might otherwise prevail in the open market, including by entering stabilizing bids, effecting syndicate covering transactions or imposing penalty bids, each of which is described below.

These transactions may be effected on an exchange, if the securities are listed on that exchange, or in the over-the-counter market or otherwise.

Any underwriters to whom offered securities are sold for public offering and sale may make a market in such offered securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice.

Any securities that qualify for sale pursuant to Rule 144 or Regulation S under the Securities Act, may be sold under Rule 144 or Regulation S rather than pursuant to this prospectus.

To the extent that the selling shareholders make sales to or through one or more underwriters or agents in at-the-market offerings, the selling shareholders will do so pursuant to the terms of a distribution agreement among us, the selling shareholders and the underwriters or agents. If the selling shareholders engage in at-the-market sales pursuant to a distribution agreement, the selling shareholders will sell our ordinary shares to or through one or more underwriters or agents, which may act on an agency basis or on a principal basis. During the term of any such agreement, the selling shareholders may sell ordinary shares on a daily basis in exchange transactions or otherwise as the selling shareholders agree with the underwriters or agents. The distribution agreement will provide that any ordinary shares sold will be sold at prices related to the then prevailing market prices for our ordinary shares. Therefore, exact figures regarding proceeds that will be raised or commissions to be paid cannot be determined at this time and will be described in a prospectus supplement. Pursuant to the terms of the distribution agreement, the selling shareholders also may agree to sell, and the relevant underwriters or agents may agree to solicit offers to purchase, blocks of our ordinary shares. The terms of each such distribution agreement will be set forth in more detail in a prospectus supplement to this prospectus.

TABLE OF CONTENTS

In the event that any underwriter or agent acts as principal, or broker-dealer acts as underwriter, it may engage in certain transactions that stabilize, maintain or otherwise affect the price of our securities. We will describe any such activities in the prospectus supplement relating to the transaction.

The selling shareholders may enter into derivative transactions with third parties or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, such third parties (or affiliates of such third parties) may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, such third parties (or affiliates of such third parties) may use securities pledged by the selling shareholders or borrowed from the selling shareholders or others to settle those sales or to close out any related open borrowings of shares, and may use securities received from the selling shareholders in settlement of those derivatives to close out any related open borrowings of shares. The third parties (or affiliates of such third parties) in such sale transactions will be underwriters and, if not identified in this prospectus, will be identified in the applicable prospectus supplement (or a post-effective amendment).

The selling shareholders may loan or pledge securities to a financial institution or other third party that in turn may sell the securities using this prospectus. Such financial institution or third party may transfer its short position to investors in our securities or in connection with a simultaneous offering of other securities offered by this prospectus or in connection with a simultaneous offering of other securities offered by this prospectus.

Certain legal matters with respect to Israeli law and with respect to the validity of the offered securities under Israeli law will be passed upon for us by Gross, Kleinhendler, Hodak, Halevy, Greenberg & Co., Tel-Aviv, Israel.

In addition, we are not required under the Exchange Act to file periodic reports and financial statements as frequently or as promptly as U.S. companies whose securities are registered under the Exchange Act.

The SEC allows us to “incorporate by reference” information into this prospectus, which means that we can disclose important information to you by referring you to other documents which we have filed or will file with the SEC. We are incorporating by reference in this prospectus the documents listed below and all amendments or supplements we may file to such documents, as well as any future filings we may make with the SEC on Form 20-F under the Exchange Act before the time that all of the securities offered by this prospectus have been sold or de-registered:

In addition, any reports on Form 6-K submitted to the SEC by the registrant pursuant to the Exchange Act after the date of the initial registration statement and prior to effectiveness of the registration statement that we specifically identify in such forms as being incorporated by reference into the registration statement of which this prospectus forms a part and all subsequent annual reports on Form 20-F filed after the effective date of this registration statement and prior to the termination of this offering and any reports on Form 6-K subsequently submitted to the SEC or portions thereof that we specifically identify in such forms as being incorporated by reference into the registration statement of which this prospectus forms a part, shall be considered to be incorporated into this prospectus by reference and shall be considered a part of this prospectus from the date of filing or submission of such documents.

ENFORCEABILITY OF CIVIL LIABILITIES

We are incorporated under the laws of the State of Israel. Service of process upon us and upon our directors and officers and the Israeli experts named in this prospectus, substantially all of whom reside outside the United States, may be difficult to obtain within the United States. Furthermore, because substantially all of

TABLE OF CONTENTS

our assets and substantially all of our directors and officers are located outside the United States, any judgment obtained in the United States against us or any of our directors and officers may not be collectible within the United States.

We have irrevocably appointed Caesarstone USA, Inc. as our agent to receive service of process in any action against us in any United States federal or state court arising out of this offering or any purchase or sale of securities in connection with this offering. The address of Caesarstone USA, Inc. is 6840 Hayvenhurst Ave. Suite 100, Van Nuys, California 91406.

We have been informed by our legal counsel in Israel, Gross, Kleinhendler, Hodak, Halevy, Greenberg & Co., that it may be difficult to initiate an action with respect to United States securities law in Israel. Israeli courts may refuse to hear a claim based on an alleged violation of United States securities laws reasoning that Israel is not the most appropriate forum to hear such a claim. In addition, even if an Israeli court agrees to hear a claim, it may determine that Israeli law and not United States law is applicable to the claim. If United States law is found to be applicable, the content of applicable United States law must be proved as a fact by expert witnesses which can be a time-consuming and costly process. Certain matters of procedure may also be governed by Israeli law.

Subject to certain time limitations and legal procedures, Israeli courts may enforce a United States judgment in a civil matter which, subject to certain exceptions, is non-appealable, including judgments based upon the civil liability provisions of the Securities Act and the Exchange Act and including a monetary or compensatory judgment in a non-civil matter, provided that:

Even if these conditions are met, an Israeli court will not declare a foreign civil judgment enforceable if:

If a foreign judgment is enforced by an Israeli court, it generally will be payable in Israeli currency, which can then be converted into non-Israeli currency and transferred out of Israel. The usual practice in an action before an Israeli court to recover an amount in a non-Israeli currency is for the Israeli court to issue a judgment for the equivalent amount in Israeli currency at the rate of exchange in force on the date of the judgment, but the judgment debtor may make payment in foreign currency. Pending collection, the amount of the judgment of an Israeli court stated in Israeli currency ordinarily will be linked to the Israeli consumer price index plus interest at the annual statutory rate set by Israeli regulations prevailing at the time. Judgment creditors must bear the risk of unfavorable exchange rates.
