Third Quarter 2016 Unaudited Results

November 28, 2016, Mexico City — Empresas ICA, S.A.B. de C.V. (BMV: ICA), announced today its unaudited results for the second quarter of 2016, which have been prepared in accordance with International Financial Reporting Standards. During the fourth quarter of 2015, the Company suspended the sale of its social infrastructure projects. Accordingly, these projects are no longer classified as available for sale. ICA is no longer consolidating San Martín, effective on the fourth quarter of 2015. In addition, ICA is no longer consolidating Facchina as of the third quarter of 2016 and has been presented as a discontinued operation. Financial statements from prior periods have been restated for comparability to reflect the sale suspension of social infrastructure projects and the deconsolidation of Facchina.

· 3Q16 Airports and Concessions segments grew 29% and 2%, respectively versus 3Q15.

· Construction Revenues decreased 71% in 3Q16 versus 3Q15 as a result of our foreign exit strategy, including Facchina, and the completion of Mexican projects, principally urban construction works.

· Ps. 4,531 million net loss generated principally as a result of the effect of a Ps. 2,090 million foreign exchange conversion loss, and the recognition of equity value loss in Facchina, as a result of our foreign exit strategy.

· Comprehensive backlog was Ps. 52,776 million at September 30th, 2016, of which Ps. 29,360 million corresponds to ICA’s participation in non-consolidated affiliates and joint ventures.

· The company continues to focus on its operating restructuring process as well as preparing to initiate a negotiation with its debt-holders that will allow for the conclusion of its financial restructure.

Consolidated Financial Results

Third quarter Consolidated Revenues decreased 35% to Ps. 5,060 million from Ps. 7,739 million in 3Q15. This reduction was principally the result of the slow-down in Construction Revenues caused by the foreign exit strategy and the completion of urban construction works. 3Q16 Construction Revenues are stabilized compared to 1Q16.

1/ 27

Third quarter Consolidated Adjusted EBITDA went to Ps. 1,224 million and 24.2% margin from Ps. 1,713 million and 22.1% margin in 3Q15. For the 9-month accumulated period, EBITDA margin increased to 25.3% in 2016 from 23.0% in 2015. This margin increase was the result of Concessions and Airport segments growth and a reduction in general expenses.

The Consolidated Net loss was Ps. 4,531 million in 3Q16. The foreign exchange conversion loss was Ps. 2,090 million in 3Q16 and Ps 3,920 million for the 9-month accumulated period. Third quarter loss per share was Ps. 8.13 (US$ 1.66 per ADS).

Liquidity and Debt

Total consolidated debt decreased 4% to Ps. 65,005 million at September 30, 2016, as compared to Ps. 67,617 million at December 31, 2015. The decrease was principally the result of loan payments made in 1Q16 to Santander, Deutsche Bank, Barclays, and Value that were secured by the pledge of OMA B shares, payment of a working capital line to BBVA Bancomer, and scheduled amortizations of debt of operating projects from December 31^,2016 to September 30, 2016.

Total cash dropped 12% to Ps. 8,186 million at September 30, 2016 from Ps. 9,258 million at December 31, 2015. This total cash reduction was generated in the Concessions and Construction segments to boost production in major projects such as Palmillas – Apaseo El Grande toll road.

Ps.4,574 million of total cash is restricted and Ps. 3,612 is unrestricted. Ps. 2,736 million of non-restricted cash is in OMA. On November 2016, as means of preparing the execution of new projects including the new NAICM terminal foundation slab project, ICA Promotora de Infraestructura (ICAPI) and Controladora de Operaciones de Infraestructura (CONOISA) disbursed the first tranch of the Fintech convertible loan.

Comprehensive backlog

Comprehensive backlog, including ICA’s share of unconsolidated affiliates and joint ventures backlog, decreased 18% to Ps. 52,776 million at September 30, 2016 from 64,543 million at December 31,

2015, principally due to the foreign exit strategy, execution of construction work in Mexico and the deconsolidation of Facchina.

Civil Construction Backlog decreased 28% to Ps. 23,416 million at September 30, 2016 from Ps. 32,380 million at December 31, 2015, principally due to the foreign exit strategy and the completion of construction works in Mexico.

ICA’s share of unconsolidated affiliates and joint ventures backlog (mainly ICA Fluor) decreased 9% to 29,360 million at September 30, 2016 from Ps. 32,163 million at December 31, 2015 due to construction works execution during this period.

Reduction in Costs and Expenses

Technical-administrative workforce has been reduced by 51% to 1,773 as of September 30, 2016 from 3,619 as of December 31, 2015.

Financial and Operational Restructuring Activities

ICA is currently focused on the consolidation of its operational restructuring and ensuring the long term continuity of the business in order to be in the position to define its financial restructuring plan.

Subsequent Events

On November 3, 2016, the Board of Directors named Guadalupe Phillips as CEO.

On October 21st, the company was awarded a Ps. 7,555 million contract for the New Mexico City International Airport (NAICM) terminal’s foundation slab. The new contract will be reflected in the Consolidated Backlog at December 31, 2016.

On October 6, ADP announced its decision to sell its shareholding in OMA held through SETA, and ICA therefore consolidates 100% of SETA and continues to own directly and indirectly 14.3% of OMA.

Construction Revenues dropped 71% to Ps. 1,334 million in 3Q16 from Ps. 4,526 million in 3Q15 . The slow-down was caused principally by our exit from international business including the deconsolidation of Facchina and the completion of projects in Mexico principally in our urban construction business.

6/ 27

Total Concessions Revenues rose 2% to Ps. 2,023 million in 3Q16 from Ps. 1,987 million in 3Q15. The increase came principally from revenues from the operating concessions, which were partially offset by a slow-down in Revenues from concessions under construction.

Operationing concessions revenues increased 9% to Ps. 1,026 million in 3Q16 from Ps. 938 million in 3Q15. The increase came from La Piedad bypass, Mayab toll road, Rio de los Remedios toll road and Rio Verde – Ciudad Valles toll road and was partially offset by a 6% decrease in the Acapulco tunnel revenues caused by decrease in traffic volume.

Revenues from concessions under construction decreased 21% to Ps. 997 million in 3Q16 from Ps. 1,049 million in 3Q15. The reduction was caused by a slow-down in Mitla – Tehuantepec highway and Diamante Tunnel construction works, and the suspension of Barranca Larga – Ventanilla Highway construction works.

Concessions Adjusted EBITDA dropped 23% to Ps. 842 million in 3Q16 from Ps. 1,096 million in 3Q15

principally due to the fair value adjustment of the Mitla – Tehuantepec highway and Diamante Tunnel.

Concessions Net Loss went to Ps. 508 million in 3Q16 from Ps. 70 million in 3Q15 principally due to the fair value adjustment of the Mitla – Tehuantepec highway.

Average daily traffic volumes (ADTV) on operating highways increased 13% to 4,263 million vehicles in 3Q16 from 3,758 million vehicles in 3Q15 caused by an ADTV increase in all operational concessions except for the Acapulco Tunnel.

Concession debt decreased 9% to Ps. 27,818 million at September 30, 2016 from Ps. 30,534 million at December 31, 2015 principally due to the operational concession debt payments. Of this total debt, 83% is debt for projects in operation and 17% is debt related to projects in construction.

Concessions cash and cash equivalents dropped 7% to Ps. 4,692 million at September 30, 2016 from Ps. 5,042 million at December 31, 2016. The drop was caused principally by the resource application to the construction works in Palmillas – Apaseo El Grande highway.

Total debt as of September 30, 2016 decreased 4% to Ps. 65,006 million from Ps. 67,617 million at December 31, 2015.

Notes and Disclaimer

The unaudited condensed consolidated financial statements of Empresas ICA, S.A.B. de C.V. and subsidiaries have been prepared in accordance with International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB) and presented in accordance with IAS 34 “Intermediate Financial Reporting”. These financial statements include all the adjustments, including those of a normal and recurring nature, required for an adequate presentation of the results of operations. Results for interim reporting periods may not be indicative of full year results. As a result, the reading and analysis of these interim financial statements should be done in conjunction with the financial statements for the year ended December 31, 2015, which were also prepared under IFRS.

Unaudited financials: Financial statements are unaudited statements.

Prior period comparisons: Unless stated otherwise, comparisons of operating or financial results are made with respect to the comparable prior-year period. Percentages may vary due to the consideration of the units’ numbers+.

Percentage changes: Are calculated based on actual amounts.

Adjusted EBITDA: Adjusted EBITDA is not a financial measure computed under IFRS and should not be considered an indicator of financial performance or free cash flow. We define Adjusted EBITDA as net income of controlling interest plus (i) net income of non-controlling interest, (ii) discontinued operations, (iii) income taxes, (iv) share in net income of affiliates, (v) net comprehensive financing cost, (vi) depreciation and amortization, and (vii) net interest expense included in cost of sales. Our management believes that Adjusted EBITDA provides a useful measure of its performance, supplemental to net income and operating income, because it excludes the effects of financing decisions, non-controlling shareholdings, and other non-operating items. The calculation of Adjusted EBITDA is also provided as a result of requests from the financial community and is widely used by investors in order to calculate ratios and to make estimates of the total value of our company in comparison to other companies. Financial ratios calculated on the base of Adjusted EBITDA are also widely used by credit providers in order to gauge the debt servicing capacity of

companies and are relevant measures under one or more of our or our subsidiaries’ financing agreements.

Exchange rate

Amounts in U.S. dollars (US$) are converted at an exchange rate of Ps. 19.5965 per U.S. dollar as of September 30, 2016, and Ps. 17.1149 per U.S. dollar as of September 30, 2015.

Financial Derivative Instruments

ICA enters into financial derivative contracts in the subsidiaries where projects are located solely in order to reduce the uncertainty on the returns on projects. The instruments entered into are established on a notional amount. Interest rate derivatives are used in order to fix maximum financial costs. Exchange rate derivatives are entered into in order to reduce the exchange risk on projects that incur labor and materials costs in a currency different from the currency of the financing of the project, as well as to convert foreign debt into domestic currencies. ICA enters into its financings in the same currency as the source of repayment. ICA has a policy of not entering into derivatives for speculative purposes.

From an accounting perspective, there are two classifications for derivative instruments. “Hedging financial instruments” must meet the specific requirements established in IFRS. Other derivative financial instruments that do not meet IFRS requirements for hedge accounting treatment are designated as trading derivatives.

ICA values all derivatives at fair value. Fair value is based on market prices for derivatives traded in recognized markets; if no active market exists, fair value is based on other recognized valuation methodologies in the financial sector, validated by third party experts, and supported by sufficient, reliable, and verifiable information.

Fair value is recognized in the balance sheet as an asset or liability, in accordance with the rights or obligations derived from the contracts executed and in accordance with accounting norms. For hedging derivatives, changes in fair value are recorded temporarily in other comprehensive income within stockholders’ equity, and are subsequently reclassified to results at the same time that they are affected by the item being hedged. For trading derivatives, the fluctuation in fair value is recognized in results of the period as part of Comprehensive Financing Cost.
