                                 DIRECTOR REPORT

AUDITED                                                             CONSOLIDATED

Grupo Simec, S.A.B. de C.V. ("Simec") announced today its final audited results
of operations for the year ended December 31, 2007.

Acquisition of Corporacion Aceros DM, S.A. de C.V. On February 21, 2008, Simec
executed an agreement to acquire 100% of the shares of Corporacion Aceros DM,
S.A. de C.V. and certain of its affiliates ("Grupo San"). Grupo San is a long
products steel mini-mill and the second-largest corrugated rebar producer in
Mexico. Grupo San's operations are based in San Luis Potosi, Mexico. Its plants
and its 1,457 employees rely on cutting edge technology to produce 700 thousand
tons of finished products annually.

With this acquisition, Simec and Industrias CH, S.A. de C.V. ("ICH") position
themselves as the second largest producers of rebar and the largest steel
producers in Mexico, with a production capacity of approximately 4.5 million
tons of liquid steel and 3.8 million tons of finished products. With this
strategic acquisition, Simec and ICH will achieve a more diversified product mix
and sales mix, with 50% of sales in Mexico and 50% outside Mexico, both of which
will allow them to better address the natural cycles of the steel industry at
the domestic and global levels. Additionally, Simec and ICH have already
identified significant synergies and economies of scale that will increase
Simec's operating margins. Grupo San's central location in Mexico, where Simec
and ICH are not currently present, also represents a strong competitive
advantage since it provides several strategic benefits mainly related to
distribution given its proximity to Mexico's main cities, sea ports, and
borders. In addition, Grupo San has aggressive expansion plans in its corrugated
rebar business, which ICH and Simec will support and promote to satisfy the
growing demand for this product resulting from the Mexican Government's
aggressive infrastructure plan.

Simec, the main subsidiary of ICH, will acquire 100% of the shares of Grupo San.
The transaction is valued at 850 million U.S. dollars, 85% of which will be paid
with cash generated by the company's operations and by the company's stock
public offering, which took place in February 2007. This acquisition confirms
the growth strategy that has characterized ICH, reaffirming its position as a
consolidator in the steel sector.

This acquisition is subject to the approval of Mexico's federal competition
commission, Comision Federal de Competencia, as well as Simec's shareholders'
meeting. Grupo San's shareholders were advised by Lehman Brothers, Inc. and by
the law office of Galicia y Robles, S.C. Simec was represented by the law office
of Mijares, Angoitia, Cortes y Fuentes, S.C.

Year Ended December 31, 2007 compared to Year Ended December 31, 2006

Net Sales

Net sales increased 3% to Ps. 24,106 million in 2007 compared to Ps. 23,515
million in 2006. Shipments of finished steel products increased 0.5% to 2,693
thousand tons in 2007 compared to 2,673 thousand tons in 2006. Total sales
outside of Mexico in 2007 increased 7% to Ps. 17,031 million compared with Ps.
15,939 million in 2006, while total Mexican sales decreased 7% from 7,576
million in 2006 to Ps. 7,075 million in 2007. The increase in sales can be
explained by higher shipments during 2007, compared with 2006 (14,000 tons
increase). The increase in tons shipped originated mainly in the plant of
Apizaco and compensated for the two unexpected stoppages in the rolling lines of
the plants in Guadalajara and



Apizaco due during the periods July 5-8, July 10-13, and September 10-15, as a
result of the shortage of natural gas due to the explosions on the property of
Petroleos Mexicanos.

Direct Cost of Sales

Direct cost of sales increased 7% from Ps. 19,132 million in 2006 to Ps. 20,499
million in 2007. Direct cost of sales as a percentage of net sales represented
85% in 2007 compared to 81% in 2006. The increase in the Direct Cost of Sales is
attributable mainly to an increase of 6% in real terms in the average cost of
raw materials used to produce steel products in 2007 versus 2006, primarily as a
result of increases in the price of scrap and certain other raw materials and an
increase in the labor costs per ton sold, due to the three unexpected stoppages
in the rolling lines of the plants in Guadalajara and Apizaco due during the
periods July 5-8, July 10-13, and September 10-15, as a result from the shortage
in natural gas due to the explosions on the property of Petroleos Mexicanos.

Gross Profit

Gross profit in 2007 decreased 18% to Ps. 3,607 million compared to Ps. 4,383
million in 2006. Gross profit as a percentage of net sales in 2007 was 15%
compared to 19% in 2006. The decline in gross profit is due to the increase in
cost of goods sold due to the reasons previously mentioned.

Operating Expenses

Operating expenses increased 5% to Ps. 1,423 million in 2007 compared to Ps.
1,351 million in 2006 (depreciation and amortization increased Ps. 99 million in
2007 compared to 2006) but remained stable at 6% of net sales.

Operating Profit

Operating profit decreased 28% from Ps. 3,032 million in 2006 to Ps. 2,184
million in 2007. Operating profit as a percentage of net sales was 9% in 2007
compared to 13% in 2006. The decline in operating profit is due to the increase
in cost of goods sold due to the reasons previously mentioned.

Comprehensive Financial Cost

Comprehensive financial cost in 2007 represented a gain of Ps. 40 million
compared with a expense of Ps. 63 million in 2006. Net interest income was Ps.
273 million in 2007, compared with Ps. 47 million in 2006 due to larger cash
balances during this year partly reflecting our recent capital increase in
February 2007. At the same time we registered an exchange loss of Ps. 38 million
in 2007 compared with an exchange loss of Ps. 37 million in 2006, reflecting a
0.1% decrease in the value of the peso versus the dollar in 2007 compared to
2006. Simec recorded a loss from monetary position of Ps. 195 million in 2007
compared to a loss from monetary position of Ps. 73 million in 2006, reflecting
the domestic inflation rate of 3.6% in 2007 as compared to a 4% inflation rate
in 2006.

Other Expenses (Income) net

The company recorded other income net of Ps. 21 million in 2007 compared to

in 2007 from Ps. 2,399 million in 2006.

467 million of net resources used by financing activities in 2006. Net resources
used in investing activities (to acquire property, plant and equipment, other
non-current assets and liabilities) were Ps. 484 million in 2007 versus net

equipment, other non-current assets and liabilities and proceeds for insurance
claim) of Ps. 13 million in 2006.

STOCK EXCHANGE CODE:  SIMEC                                QUARTER: 4 YEAR: 2007
GRUPO SIMEC, S.A.B. DE C.V.

                            FINANCIAL STATEMENT NOTES

AUDITED                                                             CONSOLIDATED

(1) Operations preparation bases and summary of significant accounting policies:

Grupo Simec, S.A. de C.V. and its Subsidiaries ("the Company") are subsidiaries
of Industrias CH, S.A.B. de C.V. ("ICH"), and their main activities consist of
the manufacturing and sale of steel products primarily destined for the
construction sector of Mexico and other countries.

Significant accounting policies and practices followed by the Companies which
affect the principal captions of the financial statements are described below:

a. Financial statement presentation - The consolidated financial statements have
been prepared in accordance with principles generally accepted in Mexico, which
include the recognition of the effects of inflation on the financial information
and the presentation in constant Mexican pesos.

b. Principles of Consolidation - As part of the financial debt restructuring
agreement into during 1997, Compania Siderurgica de Guadalajara, S.A. de C.V.
("CSG") assumed all of the debt of the Company in return for an equity interest
in its subsidiaries. As a result of the above, the Company is the principal
shareholder of CSG, and CSG is the principal shareholder of the other
subsidiaries that Grupo Simec, S.A. de C.V. ("Simec") controlled before the
restructuring.

The main subsidiaries of CSG are the following:

o (degree) Compania Siderurgica de California, S.A. de C.V.
o (degree) Industrias del Acero y del Alambre, S.A. de C.V.
o (degree) Pacific Steel Inc.
o (degree) SimRep Corporation and PAV Republic and Subsidiaries

All significant intercompany balances and transactions have been eliminated in
consolidation.

c. Cash and cash equivalents - The Company considers short-term investments with
original maturities not greater than three months to be cash equivalent. Cash
equivalents include temporary investments and Mexican Government Treasury Bonds,
and are stated at market value, which approximates cost plus earned interest.
Any increase in market value is credited to operations for the period.

d. Inventories - The inventories are originally stated at average cost and
subsequently adjusted to replacement value at the balance sheet date. The
replacement values do not exceed market and are determined as follows:

Billet finished goods and work in process - At the latest production cost for
the month.

Raw materials - According to purchase prices prevailing in the market at the
balance sheet date.

Materials, supplies and rollers - At historical cost, restated by applying the
steel industry inflation index.



The Company presents as non-current inventories the rollers and spare parts,
which according to historical data and production trends will not be used within
a one-year period.

e.- Derivative financial instruments-- The Company is using derivative financial
instruments for hedging risks associated with natural gas prices and conducted
studies on historical consumption, future requirements and commitments; thus it
avoided exposure to risks other than the normal operating risks. Management of
the Company examines its financial risks by continually analyzing price, credit
and liquidity risks.

The Company uses futures contracts for hedging risks from fluctuations in
natural gas prices, which are based on demand and supply at the principal
international markets.

As applicable, the Company recognized the fair value of instruments either as
liabilities or assets. Such fair value and thus, the value of these assets or
liabilities were restated at each month's-end. The Company opted for the early
adoption of Bulletin C-10 "Derivative Financial Instruments and Hedging";
therefore, at December 31, 2003 the fair value of natural gas in force during
2004, 2005 and 2006 and which effective portions will not be offset against the
asset risks until consumed, were recognized within the comprehensive income
account in stockholders' equity.

f. Property, plant and equipment - Property, plant and equipment of domestic
origin are restated by using factors derived from The National Consumer Price
Index ("NCPI") from the date of their acquisition, and imported machinery and
equipment are restated by applying devaluation and inflation factors of the
country of origin. Depreciation recorded in the consolidated statement of income
(loss) is computed based upon the estimated useful life and the restated cost of
each asset. In addition, Financial expense incurred during the construction
period is capitalized as construction in progress. The capitalized amounts are
restated using a factor derived from the NCPI cumulative from the date of
capitalization through period-end and are amortized over the average
depreciation period of the corresponding assets. The estimated useful lives of
assets as of December 31, 2007 are as follows:

                                                               Years
                                                               -----
           Buildings......................................   15 to 50
           Machinery and equipment .......................   10 to 40
           Buildings and improvements (Republic)..........   10 to 25
           Land improvements (Republic)...................    5 to 25
           Machinery and equipment (Republic).............    5 to 20

g. Other assets - Organization and pre-operating expenses are capitalized and
restated using a factor derived from the NCPI cumulative from the date of
generation through period-end, and their amortization is calculated by the
straight-line method over a period of 20 years.

h. Seniority premiums and severance payments - According to Federal Labor Law,
employees are entitled to seniority premiums after fifteen years or more of
services. These premiums are recognized as expenses in the years in which the
services are rendered, using actuarial calculations based on the projected unit
credit method, and since 1996 by applying real interest and salary increases.

Any other payments to which employees may be entitled in case of separation,
disability or death, are charged to operations in the period in which they
become payable.

i. Pension plan - Until 1995, the Company provided pension benefits for all
personnel with a minimum of 10 years of service and 35 years of age. The Company
had established an irrevocable trust for its contributions, which were based on
actuarial calculations. In December 1995, the board of directors of the Company,
in



agreement with the trade union, discontinued these benefits and related
contributions to the trust fund. This decision was made because of the new
Mexican pension fund system, Administradoras de Fondos para el Retiro, which
establishes similar benefits for the employees. The balance of the trust fund
will be applied to the retirement benefits of qualifying employees until the
fund is exhausted due to the irrevocable status of the fund.

The Company does not have any contractual obligation regarding the payment of
pensions of retirements.

j. Cost of sales - Cost of sales related to sales of inventory items is recorded
at standard cost, which approximates the replacement cost at the date of sale.

k. Income tax and employee profit sharing - In 1999, the Mexican Institute of
Public Accountants issued Bulletin D-4, "Accounting for Income and Asset Taxes
and Employee Profit Sharing", which is effective for all fiscal years beginning
January 1, 2000. Bulletin D-4 establishes financial accounting and reporting
standards for the effects of asset tax, income tax and employee profit sharing
that result from enterprise activities during the current and preceding years.

The Company and its subsidiaries are included in the consolidated tax returns of
the company's parent.

l. Foreign currency transactions and exchange differences - All transactions in
foreign currency are recorded at the exchange rates prevailing on the date of
their execution or liquidation. Foreign currency denominated assets and
liabilities are translated at the exchange rates prevailing at the balance sheet
date. Any exchange differences incurred with regard to assets or liabilities
denominated in foreign currency are charged to operations of the period and are
included in financial income (expense) in the accompanying consolidated
statements of income (loss).

For consolidation purposes, the financial statements of the subsidiaries abroad,
SimRep and subsidiaries, Pacific Steel and Undershaft Investment, were
translated into pesos in conformity with Mexican accounting Bulletin B-15,
Transactions in Foreign Currency and Translation of Financial Statements of
Foreign Operations.

The subsidiary SimRep was considered as a foreign entity for translation
purposes; therefore the financial statements as reported by the subsidiary
abroad were adjusted to conform with Mexican GAAP, which includes the
recognition of the effects of inflation as required by Mexican accounting
Bulletin B-10, applying inflation adjustment factors derived from the U.S.
Consumer Price Index (CPI) published by the U.S. labor department, The financial
information already restated to include inflationary effects, is translated to
Mexican pesos as follows:

-By applying the prevailing exchange rate at the consolidated balance sheet date
for monetary and non-monetary assets and liabilities.

-By applying the prevailing exchange rate for stockholders' equity accounts, at
the time capital contributions were made and earnings were generated.

-By applying the prevailing exchange rate at the consolidated balance sheet date
for revenues and expenses during the reporting period.

-The related effect of translation is recorded in stockholders' equity under the
caption Equity adjustments for non monetary assets.

-The resulting amounts were restated applying adjustment factors derived from
the NCPI, in conformity with Mexican accounting Bulletin B-10.

The subsidiaries Pacific Steel and Undershaft Investment, were considered an
"integral part of the operations" of the Company; and the financial statements
of such subsidiaries were translated into Mexican pesos as follows:



By applying the prevailing exchange rate at the consolidated balance sheet date
for monetary items. By applying the prevailing exchange rate at the time the
non-monetary assets and capital are generated, and the weighted average exchange
rate of the period for income statement items.

The related effect of translation is recorded in the statement of operations as
part of the caption Comprehensive financing cost. The resulting amounts were
restated applying adjustment factors derived from the Mexican NCPI, in
conformity with Mexican accounting Bulletin B-10.

m. Geographic concentration of credit risk - The Company sells its products
primarily to distributors for the construction industry with no specific
geographic concentration. Additionally, no single customer accounted for a
significant amount of the Company's sales, and there were no significant
accounts receivable from a single customer or affiliate at December 31, 2007 and
at December 31, 2007, direct sales to two customers accounted for approximately
10% and 16.6% of the Republic's sales. The Company performs evaluations of its
customers' credit histories and establishes and allowance for doubtful accounts
based upon the credit risk of specific customers and historical trends.

n. Other income (expenses) - Other income (expenses) shown in the consolidated
statements of operations primarily includes other financial operations.

o. Gain on monetary position - The gain on monetary position in the consolidated
statements of income (loss) is determined by applying to net monetary assets or
liabilities at the beginning of each month the factor of inflation derived from
the NCPI and is restated at period-end with the corresponding factor.

p. Restatement of capital stock and retained earnings (losses) - This is
determined by multiplying capital stock contributions and retained earnings
(losses) by factors derived from the NCPI, which measure the cumulative
inflation from the date when capital stock contributions were made and earnings
(losses) were generated, through the latest period-end.

q. Effect of restatement of stockholders' equity - The effect resulting from
restating stockholders' equity includes the accumulated effect from holding
non-monetary assets, which represents the change in the specific price level of
those assets compared to the change in the NCPI.

(2) Financial Debt:

At December 31, 2007 Simec's total consolidated debt consisted of U.S. $302,000
of 8 7/8% medium-term notes ("MTN's") due 1998 (accrued interest at December 31,
2007 was U.S. $363,703 dollars. At December 31, 2006, Simec's total consolidated
debt consisted of U.S. $302,000 of 8 7/8% medium-term notes ("MTN's") due 1998
(accrued interest at December 31, 2006 was U.S. $336,525 dollars.

(3) Commitments and contingent liabilities:

a. Pacific Steel, Inc. (a wholly-owned subsidiary located in the U.S.A.) has
been named in various claims and suits relating to the generation, storage,
transport, disposal and cleanup of materials classified as hazardous waste. The
Company has accrued approximately Ps. 14,727 (U.S. $1,355,297) at December 31,
2007, (included in accrued liabilities) relating to these actions; the reduction
of this reserve from previous levels reflects clean-up activities undertaken by
Simec. Management believes the ultimate liability with respect to this matter
will not exceed the amounts that have been accrued.

b. The Company is subject to various other legal proceeding and claims, which
have arisen, in the ordinary course of its business. It is the opinion of
management that their ultimate resolution will not have a material adverse
effect on the Company's consolidated financial position or consolidated results
of operations.

Foreign currency transactions and exchange differences - All transactions in
foreign currency are recorded at the exchange rates prevailing on the date of
their execution or liquidation. Foreign currency denominated assets and
liabilities are translated at the exchange rates prevailing at the balance sheet

pesos in conformity with Bulletin B-15 "Transactions in Foreign Currency and
Translation of Financial Statements of Foreign Operations".

      prevailing at the date the transactions occurred.

      financial income (expense) in the statement of income (loss).

      inflation in accordance with the dispositions of Bulletin B-10 using the
      NCPI, where such effects are considered significant.
