                      COMBINED COMPANY UNAUDITED PRO FORMA
                    CONDENSED COMBINED FINANCIAL INFORMATION
                     FOR THE NINE MONTHS ENDED JUNE 30, 2002

    The following table presents a pro forma condensed combined statement of
operations of Alpha Industries (the predecessor to Skyworks Solutions) and the
Washington Business and the Mexicali Operations for the nine months ended June
30, 2002. The information is presented as if the spin-off transaction and the
merger had occurred on October 1, 2001.

    The pro forma data take into account that Skyworks Solutions exchanged 0.351
of a share of Skyworks Solutions common stock for each share of Washington
common stock in the merger and paid an aggregate of $150 million for the
Mexicali operations. For financial accounting purposes, the sale of the Mexicali
operations by Conexant to Skyworks Solutions was treated as if Conexant had
contributed the Mexicali operations to Washington as part of the spin-off
transaction, and the $150 million aggregate purchase price paid by Skyworks
Solutions to Conexant was accounted for as a return of capital to Conexant.

    The merger was accounted for as a purchase business combination as defined
by Statement of Financial Accounting Standards No. 141, Business Combinations.
Because Conexant stockholders owned a majority of the outstanding shares of
Skyworks Solutions after the merger, the merger was accounted for as a reverse
acquisition in which Alpha Industries survived. Accordingly, for accounting
purposes, in the merger Alpha Industries was treated as the acquired company and
Washington was treated as the acquiring company and the historical financial
statements of the Washington Business and the Mexicali operations became those
of Skyworks Solutions after the merger. Under reverse acquisition accounting,
the purchase price of Alpha Industries was based upon the fair market value of
Alpha Industries common stock and the fair value of Alpha Industries stock
options. The purchase price of Alpha Industries was allocated to the assets and
liabilities of Alpha Industries assumed by Washington, as the acquiring company
for accounting purposes, based on their estimated fair market values at the
acquisition date.

    The unaudited pro forma condensed combined financial information is provided
for illustrative purposes only, and is not necessarily indicative of the
operating results or financial position that would have occurred if the spin-off
transaction and the merger had been consummated at the beginning of the period
presented, nor is it necessarily reflective of any future operating results or
financial position. The pro forma adjustments are preliminary and have been made
solely for purposes of developing the pro forma information. The unaudited pro
forma condensed combined financial information does not include any adjustments
related to any potential cost savings or one-time charges that may result from
the merger. The unaudited pro forma condensed combined financial information
reflects a preliminary allocation of the purchase price which is subject to
change based on finalization of the fair value of the tangible and intangible
assets acquired and liabilities assumed as of the date of the closing of the
merger.

    In the pro forma condensed combined financial information, Alpha Industries'
unaudited historical information for the nine months ended June 30, 2002 was
derived from the unaudited quarterly financial statements of Alpha Industries
for the quarter ended June 30, 2002, from Alpha Industries' Annual Report on
Form 10-K for the fiscal year ended March 31, 2002, filed with the Securities
and Exchange Commission on July 1, 2002 and from Alpha Industries' Quarterly
Report on Form 10-Q for the quarterly period ended December 30, 2001, filed with
the Securities and Exchange Commission on February 13, 2002. The
Washington/Mexicali historical statement of operations information for the nine
months ended June 30, 2002 has been derived from the unaudited combined
financial statements of the Washington Business and the Mexicali operations.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

NOTE 1 -- PURCHASE PRICE

    The purchase consideration of the merger was assumed to be approximately
$1.2 billion, based on the sum of the fair market value of the outstanding Alpha
Industries common stock and the fair value of Alpha Industries stock options and
estimated transaction costs. The estimate of the transaction costs of Washington
is preliminary. The fair market value of the shares of Alpha Industries common
stock used in determining the purchase price was $23.79 per share, which
reflects the average of the closing prices of Alpha Industries common stock on
December 17, 2001, the date the merger was announced, and on the three business
days before and after this announcement. Conexant stockholders received 0.351 of
a share of Skyworks Solutions common stock for each share of Washington common
stock issued to them in the spin-off. Alpha Industries stockholders continue to
hold their existing shares of Alpha Industries common stock as shares of
Skyworks Solutions after the merger and did not receive any new shares in the
merger.

    The fair value of Alpha Industries stock options was estimated using the
Black-Scholes option pricing model with the following assumptions: risk free
rate of return of approximately 3.5%, expected lives of approximately three
years, expected dividend rate of 0%, and volatility of approximately 120%.

    The purchase consideration is summarized as follows (in thousands):


      Fair market value of Alpha Industries common stock..        $1,054,111
      Fair value of Alpha Industries stock options .......            95,388
      Estimated transaction costs of Washington...........            33,606
                                                                  ----------
      Total...............................................        $1,183,105
                                                                  ==========

    The unaudited pro forma condensed combined financial information reflects a
preliminary allocation of the purchase price and is subject to revision, which
is not expected to be material, based on the final valuation of the net assets
acquired. The preliminary allocation of the purchase price assuming the
transaction occurred on June 30, 2002 is summarized below (in thousands):


          Working capital.........................    $  120,474
          Property, plant and equipment...........        58,700
          Amortized intangible assets.............        34,082
          Unamortized intangible assets...........         2,300
          Goodwill................................       904,221
          In-process research and development.....        65,500
          Long-term debt..........................           (73)
          Other long-term liabilities.............        (2,236)
          Deferred compensation...................           137
                                                      ----------
          Net assets acquired.....................    $1,183,105
                                                      ==========

    The excess of the purchase price over the fair value of net assets acquired
has been classified as goodwill.





                                       3
<PAGE>
    Amortized intangible assets are comprised of the following (in thousands):

          Current Technology--Semiconductor Segment..........   $17,360
          Current Technology--Ceramics Segment...............     3,900
          Customer Relationships--Semiconductor Segment......     8,600
          Customer Relationships--Ceramics Segment...........     4,100
          Covenant Not to Compete--Semiconductor Segment.....       122
                                                                -------
          Total amortized intangible assets..................   $34,082
                                                                =======

The amortization period for each of the above intangibles is ten years. The
value assigned to Current Technology for Alpha Industries' Semiconductor and
Ceramics Segments was determined by management using the income approach. Under
the income approach, the fair value reflects the present value of the projected
cash flows that are expected to be generated by the products incorporating the
current technology. The value assigned to Customer Relationships for Alpha
Industries' Semiconductor and Ceramics Segments was determined by management
using the cost approach. The cost approach determines the value of an asset as
an estimate of the current cost to purchase or replace the asset.

    Unamortized intangible assets are comprised of the following (in thousands):

                Trademark--Ceramics Segment........    $2,300
                                                       ------
                                                       $2,300
                                                       ======

    The value assigned to Trademark-Ceramics Segment was determined using the
income approach. The type of income approach was the relief from royalty
methodology. Under the relief from royalty methodology, an estimate is made as
to the appropriate royalty income that would be negotiated in an arm's length
transaction if the subject intangible asset were licensed from an independent
third-party owner.

    In-process research and development expense of $65.5 million and other
merger-related expenses of $28.8 million have been excluded from the pro forma
results as they are non-recurring and not indicative of normal operating
results.

    The pro forma condensed combined financial information is intended for
information purposes, and does not purport to represent what the combined
company's results of operations would actually have been had the transaction in
fact occurred at an earlier date, or project the results for any future date or
period. The actual results of operations of the combined company will differ,
perhaps significantly, from the pro forma amounts reflected in the pro forma
condensed combined financial information.

NOTE 2 -- PRO FORMA ADJUSTMENTS

    The following adjustments are reflected in the unaudited pro forma condensed
combined statements of operations to reflect the estimated impact of the merger
on the historical combined results of Alpha Industries and Washington/Mexicali:

          (1) Special charges consist of in-process research and development,
     merger expenses, a write-down of goodwill associated with the acquisition
     of the Philsar Bluetooth business, a write-down of assembly and test
     capacity, and restructuring charges for both Alpha Industries and
     Washington/Mexicali related to a reduction in force and consolidation of
     facilities.

          (2) To record the incremental amortization expense resulting from the
     adjustments to record Alpha Industries amortized intangible assets at
     estimated fair value utilizing the straight-line method over a useful life
     of ten years and to record the amortization of unearned compensation
     related to unvested stock options held by Alpha Industries' employees at
     the time of the closing.

          (3) To eliminate in-process research and development of $65.5 million
     and other merger-related expenses of $28.8 million as they are
     non-recurring and not indicative of normal operating results.

          (4) To record the interest expense on the short-term promissory note
     from Skyworks Solutions to Conexant. The rate of 13% used in these
     calculations reflects the terms of the note provided under the Mexican
     stock and asset purchase agreement. Subsequent to the period presented,
     Skyworks Solutions announced that it intends to issue convertible
     subordinated notes at an annual interest rate of 4.75%. Skyworks Solutions
     intends to use up to $105 million of these notes to prepay this short-term
     promissory note to Conexant. For each 1% decrease in the interest rate, the
     impact would be to increase income before income taxes by $1.1 million for
     the nine months ended June 30, 2002.


                                       4
<PAGE>

          (5) To record the income tax effects of the merger and of the pro
     forma adjustments.

          (6) Pro forma per share data is based on the number of Alpha
     Industries common shares that would have been outstanding had the merger
     occurred at the beginning of each period presented. In order to compute the
     number of shares used in the calculation of pro forma basic and diluted
     loss per share, the weighted-average number of Conexant shares multiplied
     by the exchange ratio of 0.351 per share was added to the weighted-average
     number of Alpha Industries shares outstanding. Potentially dilutive
     securities are not taken into account when their effect would be
     anti-dilutive. A reconciliation of shares used to compute historical basic
     and diluted loss per share to shares used to compute pro forma basic and
     diluted loss per share is as follows (in thousands):

NOTE 3 -- BASIS OF PRESENTATION

    Alpha Industries' unaudited historical information for the nine months ended
June 30, 2002 was derived from unaudited quarterly financial statements of Alpha
Industries for the quarter ended June 30, 2002, the Alpha Industries' Annual
Report on Form 10-K for the fiscal year ended March 31, 2002, filed with the
Securities and Exchange Commission on July 1, 2002 and from Alpha Industries'
Quarterly Report on Form 10-Q for the quarterly period ended December 30, 2001,
filed with the Securities and Exchange Commission on February 13, 2002.
In-process research and development expense of $65.5 million and other
merger-related expenses of $28.8 million have been excluded from the pro forma
results as they are non-recurring and not indicative of normal operating
results.

NOTE 4 -- IN-PROCESS RESEARCH AND DEVELOPMENT

    As of June 30, 2002, Alpha Industries was in the process of developing new
technologies in its semiconductor and ceramics segments. The objective of the
in-process research and development effort is to develop new semiconductor
processes, ceramic materials and related products to satisfy customer
requirements in the wireless and broadband markets.

SEMICONDUCTOR

    The semiconductor segment was involved in several projects that have been
aggregated into the following categories based on the respective technologies:

   Power Amplifier

        Power amplifiers are designed and manufactured for use in different
    types of wireless handsets. The main performance attributes of these
    amplifiers are efficiency, power output, voltage of operation and
    distortion. Current research and development is focused on expanding the
    offering to all types of wireless standards, improving performance by
    process and circuit improvements and offering more integrated solutions.

    The material risks associated with the successful completion of the
in-process technology are associated with Alpha Industries' ability to
successfully finish the creation of viable prototypes and successful design of
the chips, masks and manufacturing processes required. Alpha Industries expects
to benefit from the in-process projects as the individual products that contain
the in-process technology are put into production and sold to end-users. The
release dates for each of the products within the product families are varied.
The fair value of the in-process research and development was determined using
the income approach. Under the income approach, the fair value reflects the
present value of the projected cash flows that are expected to be generated by
the products incorporating the in-process research and development, if
successful.

    The projected cash flows were discounted to approximate fair value. The
discount rate applicable to the cash flows of each project reflects the stage of
completion and other risks inherent in each project. The discount rate used in
the valuation of in-process research and development was 30 percent.
