 GRUPO SIMEC ANNOUNCES RESULTS OF OPERATIONS FOR THE FIRST THREE MONTHS OF 2006

GUADALAJARA, MEXICO, April 25, 2006- Grupo Simec, S.A. de C.V. (AMEX-SIM)
("Simec") announced today its results of operations for the three-month period
ended March 31, 2006. Net sales increased 208% to Ps. 5,612 million in the first
quarter of 2006 compared to Ps. 1,824 million in the same period of 2005, due to
the inclusion of net sales of Ps. 4,067 million generated by the newly acquired
plants of PAV Republic, Inc. ("Republic") in July 2005. Simec recorded net
income of Ps. 442 million in the first three months of 2006 versus net income of
Ps. 332 million in the first three months of 2005.

On July 22, 2005 Simec and its parent company Industrias CH, S.A. de C.V.
("ICH") acquired 100% of the stock of Republic. Simec, ICH's largest subsidiary,
acquired 50.2% of Republic's stock, and ICH purchased the remaining 49.8%. The
cash purchase price of U.S. $229 million was financed by internally generated
funds. At March 31, 2006, Republic repaid in full its outstanding bank debt,
which had maturities through 2009. Republic is the leading producer of special
bar quality (SBQ) steel in the United States and, together with Simec, is the
largest producer of this kind of steel in North America.

Simec sold 680,602 metric tons of basic steel products during the three-month
period ended March 31, 2006 (including 436,999 metric tons sold by the newly
acquired plants of Republic), an increase of 176% as compared to 246,202 metric
tons in the same period of 2005. Exports (including sales by U.S. subsidiaries)
of basic steel products were 467,729 metric tons in the three-month period ended
March 31, 2006 (including 436,999 metric tons sold by the newly acquired plants
of Republic) versus 36,796 metric tons in the same period of 2005. Additionally
Simec sold 1,290 metric tons of billet in the three-month period ended March 31,
2006 as compared to 12,870 metric tons of billet in the same period of 2005.
Prices of finished products (excluding sales by Republic) sold in the
three-month period ended March 31, 2006 decreased 13% in real terms versus the
same period of 2005.

Simec's direct cost of sales increased 303% to Ps. 4,684 million in the
three-month period ended March 31, 2006 (including Ps. 3,671 million relating to
the newly acquired plants of Republic) compared to Ps. 1,161 million in the same
period of 2005. The average cost of raw materials used to produce steel products
(excluding the production of Republic) decreased 9% in real terms in the
three-month period ended March 31, 2006 versus the same period of 2005,
primarily as a result of decreases in the price of scrap and certain other raw
materials.

Indirect manufacturing, selling, general and administrative expenses (including
depreciation) were Ps. 319 million in the three-month period ending March 31,
2006 (including Ps. 148 million relating to the newly acquired plants of
Republic), compared to Ps. 189 million in the same period of 2005.

Simec's operating income increased 28% to Ps. 609 million during the first
quarter 2006 (including Ps. 248 million relating to the newly acquired plants of
Republic) from Ps. 474 million in the first quarter of 2005. Operating income
was 11% (23% excluding the operating income of Republic) of net sales in the
first quarter of 2006 compared to 26% of net sales in the first quarter of 2005.



Simec recorded other income, net, from other financial operations of Ps. 11
million in the three-month period ended March 31, 2006 compared to other income,
net, of Ps. 5 million in the same period of 2005. In addition, Simec recorded a
provision for income tax and employee profit sharing of Ps. 94 million in the
three-month period ended March 31, 2006 versus a provision of Ps. 148 million in
the same period of 2005.

Simec recorded financial expense of Ps. 5 million in the three-month period
ended March 31, 2006 compared to financial income of Ps. 1 million in the same
period of 2005 as a result of (i) net interest income of Ps. 1 million in the
three-month period ended March 31, 2006 compared to Ps. 2 million of net
interest income in the same period of 2005, (ii) an exchange gain of Ps. 1
million in the three-month period ended March 31, 2006 compared to an exchange
gain of Ps. 6 million in the same period of 2005 reflecting a decrease of 1.6%
in the value of the peso versus the dollar in the three-month period ended March
31, 2006 compared to a decrease of 0.3% in the value of the peso versus the
dollar in the same period of 2005 and (iii) a loss from monetary position of Ps.
7 million in the three-month period ended March 31, 2006 compared to a loss from
monetary position of Ps. 7 million in the same period of 2005, reflecting the
domestic inflation rate of 0.9% in the three-month period ended March 31, 2006
compared to the domestic inflation rate of 0.8% in the same period of 2005.

At March 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 March 31, 2006

consisted of approximately $38 million of U.S. dollar-denominated debt.

All figures were prepared in accordance with Mexican generally accepted
accounting principles and are stated in constant Pesos at March 31, 2006.

Simec is a mini-mill steel producer in Mexico and manufactures a broad range of
non-flat structural steel products and its subsidiary Republic is the leading
producer of special bar quality (SBQ) steel in the United States.

activities during the current and preceding years. Simec's long-term liability
resulting from the adoption of this Bulletin was Ps. 914 million at March 31,
2006 compared to Ps. 1,394 million at March 31, 2005. The effect on Simec's
consolidated statement of income in the three-month period ended March 31, 2006
was a decrease of Ps. 22 million in the provision for income tax and employee
profit sharing compared to a decrease in the provision of Ps. 44 million in the
same period of 2005. These provisions do not affect the cash flow of Simec.

                            FINANCIAL STATEMENT NOTES
                                     ANNEX 2                        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. 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  Compania Siderurgica de California, S.A. de C.V.

o  Industrias del Acero y del Alambre, S.A. de C.V.

o  Pacific Steel Inc.

o  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 includes 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 March 31, 2006 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
      Machinary 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).

The financial statements of foreign subsidiaries are translated into Mexican
pesos in conformity with Bulletin B-15 "Transactions in Foreign Currency and
Translation of Financial Statements of Foreign Operations".

Pacific Steel and Undershaft investments are considered to be "integrated
foreign operations", as defined in Bulletin B-15, and accordingly such financial
statements were translated as follows:

-     Monetary items at the exchange rate at the balance sheet date.

-     Non-monetary items and stockholders' equity at the exchange rate
      prevailing at the date the transactions occurred.

-     Income and expense items at an appropriate average exchange rate.

-     The resulting foreign currency translation differences are included in the
      financial income (expense) in the statement of income (loss).

-     All resulting Mexican peso amounts are restated for the effects of
      inflation in accordance with the dispositions of Bulletin B-10 using the
      NCPI, where such effects are considered significant.

SimRep and subsidiaries are considered to be "foreign operations", as defined in
Bulletin B-15, and accordingly such financial statements were translated as
follows:

-     Monetary and non-monetary items at the exchange rate at the balance sheet
      date.

-     Income and expense items at the exchange rate at the balance sheet date.

-     The resulting foreign currency translation differences are included in the
      stockholders' equity.

-     All resulting Mexican peso amounts are restated for the effects of
      inflation in accordance with the dispositions of Bulletin B-10 using the
      NCPI, where such effects are considered significant.

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 March 31, 2006 and
2005. 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 March 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 March 31, 2006
was U.S. $316,356 dollars. At December 31, 2005, Simec's total consolidated debt
consisted of U.S. $38 million (Ps. 410 million), of which $33.4 million was debt
held by GE Capital, $4.3 million dollars held by the Ohio Department of
Development Loan, and U.S. $302,000 of 8 7/8% medium-term notes ("MTN's") due
1998 (accrued interest at December 31, 2005 was U.S. 309,311 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. 14,687 (U.S. $1,341,141) at March 31,
2006, (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.

c. Compania Siderurgica de Guadalajara, S.A. de C.V. has entered into a gas and
liquid oxygen purchase agreement with Praxair de Mexico, S.A. de C.V., under
which it is committed to acquire monthly over a fifteen-year period beginning
January 1, 1989, a certain amount of product. At present required purchases
amount to Ps. 1,436 per month.

                                    ANNEX 14                        CONSOLIDATED

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).

The financial statements of foreign subsidiaries are translated into Mexican
pesos in conformity with Bulletin B-15 "Transactions in Foreign Currency and
Translation of Financial Statements of Foreign Operations".

Pacific Steel and Undershaft investments are considered to be "integrated
foreign operations", as defined in Bulletin B-15, and accordingly such financial
statements were translated as follows:

-     Monetary items at the exchange rate at the balance sheet date.

-     Non-monetary items and stockholders' equity at the exchange rate
      prevailing at the date the transactions occurred.

-     Income and expense items at an appropriate average exchange rate.

-     The resulting foreign currency translation differences are included in the
      financial income (expense) in the statement of income (loss).

-     All resulting Mexican peso amounts are restated for the effects of
      inflation in accordance with the dispositions of Bulletin B-10 using the
      NCPI, where such effects are considered significant.

SimRep and subsidiaries are considered to be "foreign operations", as defined in
Bulletin B-15, and accordingly such financial statements were translated as
follows:

-     Monetary and non-monetary items at the exchange rate at the balance sheet
      date.

-     Income and expense items at the exchange rate at the balance sheet date.

-     The resulting foreign currency translation differences are included in the
      stockholders' equity.

-     All resulting Mexican peso amounts are restated for the effects of
      inflation in accordance with the dispositions of Bulletin B-10 using the
      NCPI, where such effects are considered significant.
