GROWtH letter from the IN CHAIRMAn DIsPAtCHes AND of the ebitda board MAINlY OWING to COst efficiency. the CONDORCOCHA AND AtOCONGO PlANts ReACHeD 100.0% OF their expanded CAPACItY. stock surpluses enabled ResuMPtION OF exports. the PROGRe-sOl NetWORK Is the largest NetWORK OF HARDWARe stores IN the COuNtRY. To ThE ShArEhoLDErS of unacem: During 2014, a significant slowdown has been observed in Peru: the country went from 5.5% growth in 2013, to 2.4% in 2014. the impact of suspending public works and the reduced private investment during the first half of the year had a considerable effect on self-construction, causing our cement dispatches to grow only 1.6% as of the end of the year. Nevertheless, the ebitda grew 14.3%, mainly explained by the increasing cost efficiency. With regard to our operations, in 2014 both our Condorcocha and Atocongo plants reached virtually 100.0% of their expanded capacity. For our clinker production, we worked with a combined utilization rate of 89.0%, and for cement, with a combined utilization rate of 75.0%, which enabled us to lower our fuel and electric power costs; furthermore, the reduced growth of the local cement market, added to the increased clinker production, generated stock surpluses so that we were able to resume our export operations, which this year reached a volume of 423,835 tons of clinker in the last eight months of the year. Meanwhile, we continued working in strengthening our commercial relations through the entire value chain. the Progre-sol network reached 288 hardware points of sale and, for the sixth year in a row, is the leading hardware stores network in the country and adds to the 40 direct points of sale in the central and northeastern Andean regions. In addition, Cemento sol entered the ranking of most valued brands in latin America, according to the consulting firm Millward Brown. this was also a great year for our subsidiaries, which have kept their operating and resource generation levels. unicon and Firth continue leading the ready mix industry, with more than 56.0% share of the national market and, despite the slowdown in important infrastructure projects, they were able to keep the combined dispatch of both companies at levels similar to those of the previous year. CelePsA had a slightly higher electricity production than in 2013; however, on the other hand, its revenues were 1.5% lower due to the unfavorable commercial situation of the energy market. Furthermore, this year was quite meaningful for CelePsA, as it started to grow. In November, it acquired Hidro Marañón, a 20 MW generation project with renewable energy resources (ReR) that will demand a total investment of us$ 60.0 million and will be entirely funded with CelePsA cash flow. In the united states we continue our efforts to achieve that both Drake Cement and Drake Materials streamline their operations in order to have the adequate conditions to meet the surge of demand in Arizona. this year, Drake Cement produced almost 315,000 short tons of cement and we feel confident that finally, the projections of the Portland Cement Association for the next five years will reach an average growth of more than 10.0% per year in Arizona, which will enable Drake to generate positive cash flows. With our subsidiaries PReANsA PeRÚ and PReANsA CHIle and with the forthcoming execution of the PReANsA COlOMBIA project, we are committed to the development of efficient and safe engineering solutions so that we may expand the products and services we offer. growth RegISteRed by CeMent dispatches was 1.6%. 16 2014 AnnuAl RepoRt 17

2014 WAs AN IMPORtANt YeAR FOR OuR subsidiaries. ReleVANt MIlestONe IN OuR GROWtH strategy. ACQuIsItION OF 98.57% shares OF WHAt today Is unacem ecuador s.a. successful IssuANCe OF CORPORAte BONDs IN the INteRNAtIONAl MARKet. CONtINue CReAtING VAlue FOR OuR shareholders AND All OuR stakeholders. undoubtedly, 2014 also represents a relevant milestone in our growth strategy. the acquisition of 98.57% of lafarge Cements s.a., now unacem ecuador, the second largest cement producer in the ecuadorian market, turns us into a company that is becoming significant in the region. We are confident that this acquisition will produce great synergies aside from increasing our production capacity of cement by 18.0%. In 2014, unacem ecuador reached sales amounting to us$ 186.0 million and an approximate market share of 22.0%. this new investment represents great potential to develop new business lines and offer new solutions to our clients in ecuador, always aligned with the purpose of fostering the development of society, as we have been doing for more than 60 years in Peru. to materialize this acquisition, we decided to enter the international capitals market. this process represented a challenge for unacem and all its subsidiaries, as the issuance involved arduous work for all the companies in the group. At the end of October, the trust of the international capitals market was reflected in a successful issuance of corporate bonds that totaled us$ 625.0 million with 7 year maturity. this first international issuance of unacem achieved a demand of almost us$ 3.0 billion and represents the largest high-yield issuance in the history of Peru, confirming the trust of the international market in the company and compelling us to keep working towards creating value for our shareholders, our investors and, in general, all our stakeholders. Finally, but not less important, the gratitude of the Board of Directors to sindicato de Inversiones y Administración s.a., who continued to be in charge of the General Management of unacem; to Inversiones Andino s.a. and ARPl tecnología Industrial, who offer us administrative and technical consulting services; and our special recognition to each and every one of our employees who engage one hundred per cent of their efforts and commitment to stand up to the challenges presented. We will continue placing our bets on the continuous growth of our production activities, fostering the development of the country and the region and creating value in new markets, with new products for all our stakeholders. I invite you to learn about the most relevant events of the performance of unacem during 2014.

otavalo PLAnT, ImBABurA, ECuADor. this was an important year for unacem. In addition to the good operating results of our Atocongo and Condorcocha plants, which recorded historical monthly production and dispatch records in the local cement market, we have taken huge steps in the consolidation and diversification of our cement and precast products operations in the region. this has boosted our growth strategy which, through our subsidiaries, strengthens our commitment to our stakeholders. 28 2014 MeMoRIA AnnuAl RepoRt AnuAl 29

The process lasted several months, as in order to complete the transaction we had to obtain the approval of the competent authorities of Ecuador. Thus, in October, we obtained the authorization for the direct acquisition from the Superintendence of Market Power Control and in November, we received the approval from the Superintendence of Companies and Securities. On November 25, 2014, through our subsidiary Inversiones Imbabura S.A., we acquired by public share offering in the Quito Stock Exchange, 98.57% of the shares of Lafarge Cementos S.A. and as of February 20, 2015, we completed the acquisition of 98.9%, for a total value of US$ 517.1 million, thus consolidating our expansion in the region. UNACEM Ecuador has a plant in Otavalo, in the province of Imbabura. It has a production capacity of 1 million tons of clinker and almost 1.5 million tons of cement; an integrated operation with limestone reserves for more than 60 years; and a broad distribution network serving the Ecuadorian market efficiently. It is an operation that has been working with financial and operating efficiency, but, most importantly, it is located in a market with great potential for growth. With the addition of UNACEM Ecuador, UNACEM and its subsidiaries have a consolidated cement production capacity of approximately 9.7 million tons, which strengthens our growth and commitment with the region. Acquisition of UNACEM ECUADOR S.A. (formerly Lafarge Cementos S.A.) Undoubtedly, the most relevant milestone in 2014, the one that marked our consolidation as a company that starts to have a noticeable regional presence, was the acquisition of Lafarge Cementos S.A., today UNACEM Ecuador S.A. After several months of evaluation and negotiation, on May 27 we announced the acquisition of this large Ecuadorian company (subsidiary of the Lafarge group). That same day we executed the sale and purchase agreement to acquire 98.57% shares of the company; however, being a company listed in the Quito Stock Exchange, a public offer was made for 100.0% of the shares. International issuance of corporate bonds In order to materialize this important acquisition in Ecuador we had to obtain the funds required to finance the operation. This was guaranteed since May, through a firm commitment of a group of banks that granted to UNACEM a bridge loan for a total amount of US$ 560.0 million: BBVA Banco Continental S.A. BBVA Securities Inc.; Deutsche Bank AG London Branch; and The Bank of Nova Scotia Scotiabank Perú S.A. This bridge loan did not have to be disbursed. 30 2014 Annual Report 31

We reassert our long-term commitment with our shareholders to continue creating shared value. After evaluating the different possibilities to finance the long-term operation, the Board of Directors, by delegation from the Shareholders Meeting, approved the issuance of international bonds for an amount of up to US$ 700.0 million. For the placement of these bonds, UNACEM obtained the rating from two international risk agencies: Moody s, which assigned a Ba2 rating to UNACEM and its consolidated subsidiaries and Standard and Poor s, which awarded a BB+ rating. On October 28, UNACEM successfully placed a private offer of Senior Notes in the international market under Rule 144A of the Securities and Exchange Commission of the United States of America and Regulation S of the U.S. Securities Act, in the amount of US$ 625.0 million, with 7 year maturity and 5.875% rate. The issuance funds were used to finalize the acquisition of Lafarge Cementos S.A. and refinance short-term obligations. The structuring and placement agents, joint bookrunners of the transaction, were BBVA Securities Inc., Deutsche Bank Securities Inc. and Scotia Capital (USA) Inc. Otavalo Plant, Imbabura, Ecuador. It is worth highlighting that the placement of UNACEM represents the largest high yield corporate issuance of a Peruvian company in the international market. It was a multi-jurisdictional transaction that required, in addition, a close follow-up of the international capitals markets, which finally led to a successful placement operation, with a demand that exceeded four times the amount issued. This fact confirms the trust of the international market in the company and our long-term commitment with our shareholders and investors to continue creating shared value. 32 2014 Annual Report 33

ACquISItIon of preansa CHIle In January 2014, we finalized the acquisition of 51.0% of the shares of Prefabricados Andinos s.a. PReANsA CHIle for a value of us$ 7.14 million. It is a company that has been present in the Chilean market for more than 17 years, engaged in the development and manufacturing of industrialized concrete structures for industrial, commercial and infrastructure construction projects and whose plant in santiago has 24,000 m 3 of installed capacity. «the international expansion of unacem is the result of its accumulated experience, technological innovation and its firm commitment to continue creating value.

Macroeconomic Environment During 2014, the world economy continued showing moderate signs of recovery. World growth is estimated in 3.3% for 2014, with respect to the previous year, explained by the still weak results of the leading economies and the slower performance of the emerging economies. As for the emerging economies, they presented weak growth rates as a result of the slow economic evolution of the developed countries. China s growth, according to estimates, was slower than in the previous years (7.4%) owing to a weak internal demand and lower export figures, which led the authorities to apply very specific stimulus measures to counteract the situation. Latin America, meanwhile, would have grown only 1.3% mainly owing to the hard impact of the external demand resulting from the lower prices of relevant raw material such as copper, gold, silver, soybean and oil, which have fallen to their lowest level in the past years. The growth shown by the leading economies was uneven. In the Eurozone, the sequels of the crisis and the recession are still slowing down its recovery (0.8% in 2014). In turn, the United States of America counteracted this situation with a growth that exhibited expected variations: a 2.2% rate in line with the International Monetary Fund estimates, as a result of the improved employment situation (unemployment rate closed at 5.6% in December, the lowest since June 2008), added to the increased internal demand. In Peru, the growth slowdown was notorious compared to the levels of the previous years, however, moderate with respect to the largest economies in the region (Brazil, Argentina and Chile). The Peruvian economy recorded a 2.4% growth. This low figure is mostly the result of the unfavorable performance of the global economy (raw material prices and more costly external financing) and of internal structural factors that caused delays in mining projects and the contraction of public investment by local governments, generating a downturn in private investment and lower consumption. 46 2014 Annual Report 47

To counteract these effects, the government has taken measures to boost growth aimed at, for example, increasing public expenditure and tax reductions. Inflation, in turn, closed the year at 3.3%, exceeding the target range of the Central Reserve Bank of Peru (BCR, for its acronym in Spanish) and the foreign exchange rate fluctuated significantly throughout the year: the currency lost value due to the deficit in the current account of the balance of payments and to an increasing perception of upcoming higher Federal Reserve (FED) rates. The nuevo sol quotation as of the closing of the year was S/. 2.989 per US dollar (S/. 2.796 at the closing of 2013). With regard to cement, our production totaled 5,717,525 tons, a 1.5% increase with respect to the 5,631,076 tons of the previous year, enabling us to meet the local cement demand. From this total, 3,792,918 tons correspond to the production of the Atocongo plant (Lima) and 1,924,607 tons to the Condorcocha plant (Junin). 2010-2014 CEMENT PRODUCTION PER PLANT (in thousands of metric tons) The construction sector grew 1.7% during 2014. This reduction in its annual growth is mainly explained by the suspension of public and private works, in particular 7,000 Operations during the first half of the year, added to a lower growth rate in formal employment and the costlier real estate loans. 6,000 5,000 4,000 4,774 4,731 5,355 5,631 5,718 Production and dispatch in the local market 3,000 Our operations kept a steady performance throughout the year, yielding excellent 2,000 operating results. The kilns in both plants worked efficiently at 89.0% of their installed capacity. Clinker production reached 5,951,216 tons, that is, 35.8% more 1,000 than the production registered in 2013, owing basically to the operation of kiln 1 of the Atocongo plant, which was modernized at the end of 2013. This year, the 0 2010 2011 2012 2013 2014 production of clinker from both plants reached altogether a new historical monthly record, which in October totaled 578,861 tons. Condorcocha Atocongo Unacem January 2014 March 2014 We acquired 51.0% of shares of PREANSA CHILE. The Shareholders Meeting designated the 2014-2016 Board of Directors. We started the works at cement mill 8 and bagging unit 5 at the Condorcocha plant. 48 2014 Annual Report 49

Over the year and as part of the merger synergies, we have taken measures to streamline our operations and the associated costs: We suspended the operation of kiln 1 at the Condorcocha plant temporarily. This kiln had been working since 1958, at a production rate of 300 tons/day, with high costs because of its manufacturing technology. To compensate the effect of the suspension of this kiln, the Atocongo plant provided the necessary clinker. We started using a new raw material mixing system for the production of clinker, reducing the limestone stripping ratio of Atocongo. This results in a lower operating cost and improved raw material reserve. Thus, we rationalized the use of equipment in the quarries and exercised better control to avoid distortions in the quality of our products. In 2014, volume dispatched totaled 5,701,464 tons, 1.6% more than the volume reached in 2013, which totaled 5,610,572 tons. During the first half of the year, dispatch levels were similar to those in 2013; however, they were compensated with the growth registered in the second half, which continued increasing in the fourth quarter. Furthermore, our cement dispatches reached a new historical monthly record in November: 512,309 tons. 2005-2014 DOMESTIC CEMENT DISPATCH (in thousands of metric tons) 6,000 5,500 5,000 4,500 4,709 4,702 5,311 5,611 5,701 4,000 3,500 4,126 4,209 3,000 3,452 2,500 2,683 3,056 2,000 1,500 1,000 500 0 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 50 2014 Annual Report 51

Meanwhile, according to recent estimates, cement demand in the country was 11,423,524 tons, up 2.9% from 2013, estimated in 11,099,100 tons. this demand includes dispatches from national producers and an estimate of imported cement entering the country. CoMMeRCIAlIZAtIon We sell our products through two business units: bagged cement and bulk cement, which during 2014, represented 73.9% and 26.1% of the total product dispatched, respectively. the products sold by the bagged cement business unit are: Portland cement type I, under the brands Cemento Andino and Cemento sol ; Portland cement type IP, under the brands Cemento Atlas and Cemento Andino ; and cement types IPM and V, under the brand Cemento Andino. Our most recent introduction, Cemento Apu, blended cement for general use, had a great performance, evidencing a 1,028.5% growth with respect to 2013, when it was first launched to the market. this contributed to a 2.8% growth of the bagged cement business unit in 2014. Our bagged products portfolio is mainly sold through two distribution channels: the traditional hardware stores channel (consisting of the network of Progre-sol hardware stores and independent stores) and the modern hardware channel (consisting of the large self-service hardware warehouses, such as sodimac, Maestro and PROMARt). Along this line, it is worth noting that the success of Apu was so impressive that it did not only replace the sales of other products, but the brand also grew even more at the expense of the main competitors. Despite the growth of Apu, the sales of bagged Cemento sol and Cemento Andino increased 1.1% and 2.6%, respectively, with respect to the previous year. As for return, the success of Apu was also quite significant, besides contributing to reducing CO 2 emissions due to its being blended cement. During 2014, we continued focusing on our goal to optimize our bagged products portfolio in the central Coast of the country. Meanwhile, the bulk cement business unit sells Portland cement type I, IP, IPM and V, mainly supplying the ready mix sellers, hydroelectric power plants, mining, oil and construction companies and companies that manufacture cement-based products. During 2014, dispatches from this unit dropped 1.6% with respect to 2013. Recovery in this line is expected with the incorporation of improvements in the bulk business unit of unacem, aimed at serving the specific needs of this type of client. Our commercial strategy continues to be focused on innovating, strengthening the sustainable commercial relation along the entire value chain (from our plants to the hardware points of sale) and on investing in improving the services offered to our clients and to the final users of our products. Accordingly, since 2008, we keep a close relationship with hardware sellers, entrepreneurs and independents, with outstanding performance in distribution and coverage, through the Progre-sol network of hardware stores. During 2014, the Progre-sol network reached 288 points of sale and was, for the sixth consecutive year, the leading network of hardware stores in the country. In addition, outside the area of influence of Progre-sol, we keep more than 40 direct points of sale corresponding to distributors in cities of the central and northeastern Andes regions in the country, providing us with greater coverage. the bagged CeMent business unit grew 2.8%. 52 2014 AnnuAl RepoRt 53

Exports and port operations In 2014, we resumed our exports of clinker through the Conchan pier, with a total volume of 423,835 tons, representing revenues in the amount of US$ 18.6 million for the company. Main export destinations included Venezuela, Chile and Brazil. We resumed export of 423,835 tons through the Conchan pier. In turn, the tonnage of bulk solids operated through the Conchan pier dropped 31.0% with respect to 2013, as we do not import clinker anymore and, on the contrary, we have started exporting. Furthermore, there was a reduction in our coal imports due to the greater use of natural gas and the reduction of CO 2 emissions from the kilns. Integrated management system (IMS) The integrated management system is one of the most important mainstays of our operation that supports each and every one of the company s areas in streamlining their processes and, thus, our competitiveness in the sector. We currently hold ISO 9001, ISO 14001 and OSHAS 18001 certifications for the Atocongo and Condorcocha plants; and BASC (Business Alliance for Secure Commerce) certification and ISPS (International Ship and Port Facility Security) certification for the Conchan pier. Furthermore, the internal audits performed during 2014 have verified that the processes meet the goals set out and the standard requirements, and have enabled us to identify improvement opportunities in our performance. In 2014, we conducted a customer satisfaction study in Atocongo, through an independent consultant, with respect to our domestic cement clients; we verified improvements in our indicators as compared with the survey made in 2013. Along the year, we also performed environmental impact and risk assessments of the relevant processes, to ensure that the proper operating controls are in place to keep environmental impacts and safety risks within the established limits. At Condorcocha, we performed integrated audits with our contractors with regard to environmental and occupational safety and health management, to ensure that pertinent regulations are complied with. We have placed emphasis in achieving that our contractors are able to identify correctly the hazards in their work area, to evaluate the risks they represent and to implement the established controls to minimize the risk and protect workers integrity and health. 54 2014 Annual Report 55

SubSIdIARIeS And AffIlIAteS InveCo S.A. / unicon S.A. (ownership: 93.4% of InveCo / 100.0% of unicon) unicon is the country s leading company in distribution and sales of ready mix and related services and products. In addition to ready mix, the company produces and sells aggregates for construction, blocks and bricks and offers shotcrete application service for tunnel bracing. During 2014, ready mix dispatches at national level reached 2,298,357 m 3, that is, 2.0% less than in 2013, mostly explained by the slowdown in both the economy and in infrastructure projects. Meanwhile, in lima, dispatches totaled 1,752,595 m 3, 4.0% less than in the previous year. Dispatches outside the capital increased 3.0%, reaching 545,762 m 3. the commercial closing of cubic meters for new projects increased 33.0% with respect to the previous year.
