                      NOTES TO INTERIM FINANCIAL STATEMENTS



1.      Interim Financial Statements

        The accompanying unaudited financial statements have been prepared by
        Clyde Companies, Inc. (the "Company") in accordance with instructions to
        Form 10-Q and Rule 10-01 of S-X. Accordingly, certain information and
        footnote disclosures normally included in financial statements prepared
        under generally accepted accounting principles have been condensed or
        omitted pursuant to such regulations. In the opinion of management, all
        adjustments considered necessary for a fair presentation of the
        Company's financial position, results of operations and cash flows have
        been included. All such adjustments are of a normal recurring nature.
        This report on Form 10-Q for the nine months ended September 30, 1998
        should be read in conjunction with the financial statements of the
        Operating Companies (as defined in Note 2 below) and the Company as of
        and for the year ended December 31, 1997, which are included in the
        Company's Registration Statement on Form S-4 dated May 13, 1998. The
        results of operations for the nine months ended September 30, 1998 may
        not be indicative of the results that may be expected for the year
        ending December 31, 1998.

2.      Agreement and Plan of Merger

        The merger ("Merger") of W.W. Clyde & Co., Geneva Rock Products, Inc.,
        Utah Service, Inc. and Beehive Insurance Agency, Inc. (the "Operating
        Companies") with and into wholly-owned subsidiaries of the Company was
        consummated as of June 30, 1998, and in connection therewith, 4,634,791
        shares of Common Stock of the Company were issued. Each of the Operating
        Companies was affiliated with the Company as a result of common
        shareholders, common directors, and the Company's minority equity
        investment in each entity. Each Operating Company now is a wholly-owned
        subsidiary of the Company.

        The Merger was effected by exchanging shares of the Company's Common
        Stock for shares of common stock of each Operating Company held by their
        respective shareholders. The Merger was accounted for using the
        "purchase" method of accounting. The exchange ratios used in determining
        the number of shares to be exchanged were based upon independent
        valuations of each Operating Company.

        The purchase method of accounting requires consolidated results of
        operations to be reflected only from the date of Merger forward. Because
        the Merger was consummated on June 30, 1998, consolidated operating
        results are included only in the Consolidated Statements of Earnings for
        the three-month period ended September 30, 1998. Prior to June 30, 1998,
        the Company recorded only its equity in the net earnings of the
        Operating Companies.

        The following unaudited pro forma consolidated data for the nine months
        ended September 30, 1998 and the year ended December 31, 1997 presents
        the results of operations of the Company as if the Operating Companies
        had merged on January 1, 1997 (in thousands except per share data). This
        data does not purport to be indicative of the results of operations of
        the Company that might have occurred nor which might occur in the
        future.

</TABLE>


        The property, plant and equipment acquired by the Company in the Merger
        will be depreciated over periods ranging from 3 to 12 years, and the
        intangible assets are to be amortized over 15 years.

        In connection with the Merger, 18 shareholders of the Operating
        Companies (the "Dissenting Shareholders"), who collectively own the
        equivalent of 419,188 shares of Common Stock of the Company, gave notice
        that they intended to exercise their statutory dissenters' rights and
        seek payment of the fair value of their shares. Following the
        consummation of the Merger, the Dissenting Shareholders were paid an
        aggregate of $4,496,890, which is the amount the Operating Companies
        determined to be the fair value of the shares held by the Dissenting
        Shareholders on the date the Merger was consummated.

        After receiving payment for their shares in the Operating Companies, 16
        of the Dissenting Shareholders, who collectively own the equivalent of
        243,223 shares of Common Stock of the Company, notified the Operating
        Companies that, in their opinion, the fair value of their shares on the
        date of the Merger was greater than the amounts which the Operating
        Companies had paid to them for their shares, and they demanded that the
        Operating Companies pay them an additional aggregate amount of
        approximately $2,361,666. This amount is not reflected in the
        Consolidated Balance Sheets of Clyde Companies, Inc. and Subsidiaries.

        The Operating Companies believe that the amounts paid to the Dissenting
        Shareholders represented the fair value of their shares on the date of
        the Merger. Accordingly, on November 3, 1998 the Operating Companies
        filed a Petition with the Third Judicial District Court of Salt Lake
        County to request the Court to determine the fair value of the shares of
        the Operating Companies held by the Dissenting Shareholders who have
        demanded payment of additional amounts for their shares. While the
        Company believes that the amounts paid to the Dissenting Shareholders
        represented the fair value of the shares they held in the Operating
        Companies on the date of the Merger, the Company is not able to predict
        the outcome of this proceeding. See Item 1 - Legal Proceedings.

ITEM 1.   LEGAL PROCEEDINGS

        In connection with the merger (the "Merger") of W.W. Clyde & Co.
("Clyde"), Geneva Rock Products, Inc. ("Geneva Rock"), Utah Service, Inc. ("Utah
Service") and Beehive Insurance Agency, Inc. ("Beehive Insurance") (which are
together referred to as the "Operating Companies") with and into wholly owned
subsidiaries of Clyde Companies, Inc. (the "Company"), 18 shareholders of the
Operating Companies (the "Dissenting Shareholders"), who collectively own the
equivalent of 419,188 shares of Common Stock of the Company, gave notice that
they intended to exercise their statutory dissenters' rights and seek payment of
the fair value of their shares. Following the consummation of the Merger on June
30, 1998, the Operating Companies paid the Dissenting Shareholders an aggregate
amount of $4,496,890 for their shares, which is the amount the Operating
Companies determined to be the fair value of the shares held by the Dissenting
Shareholders on the date of the Merger. The Dissenting Shareholders were paid
$394.13, $2,779.36, $504.45 and $50.30 for each share of Clyde, Geneva Rock,
Utah Service and Beehive Insurance, respectively, which they held.

        After receiving payment for their shares from the Operating Companies,
16 of the Dissenting Shareholders, who collectively own the equivalent of
243,223 shares of Common Stock of the Company, notified the Operating Companies
that, in their opinion, on the date of the Merger the fair value of Clyde,
Geneva Rock, Utah Service and Beehive Insurance was $657, $5,509, $975 and $116
per share, respectively, and they demanded payment of the additional amounts,
plus interest. The aggregate additional amount demanded by the Dissenting
Shareholders, exclusive of interest, is approximately $2,361,666.

        The Operating Companies believe that the amounts they paid to the
Dissenting Shareholders represented the fair value of the shares held by the
Dissenting Shareholders on the date of the Merger. Accordingly, pursuant to Utah
Code Annotated, as amended, Section 16-10A-1330, on November 3, 1998, the
Operating Companies filed a Petition with the Third Judicial District Court of
Salt Lake County (Case No. 980911145) to request the Court to determine the fair
value of the shares of the Operating Companies held by the 16 Dissenting
Shareholders who have demanded the payment of additional amounts for their
shares. In addition, the Operating Companies requested a ruling to the effect
that the Estate of Scott Clyde did not properly exercise its dissenters' rights
with respect to Clyde and, therefore, is not entitled to payment for the shares
of Clyde which it held. The Petition named the following Dissenting Shareholders
as respondents: Terry Carlson; Scott Carlson; Claudia Snyder; Kenneth Snyder;
Kurt Gramoll; Junko Gramoll; James Gramoll; Damon Clyde; Christina Schroeder;
Brian Clyde; Ronald Clyde; Stephen W. Clyde; Robert Clyde; Marcia Clyde, as
personal representative of the Estate of Daniel Clyde, deceased; Janice Clyde,
personally; and Janice Clyde, as personal representative of the Estate of Scott
Clyde, deceased. While the Company believes that the amounts paid to the
Dissenting Shareholders represent the fair value of the shares they held in the
Operating Companies on the date of the Merger, the Company is not able to
predict the outcome of this proceeding.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

        The purpose of this section is to discuss and analyze the Company's
results of operations, financial condition, liquidity and capital resources.

OVERVIEW

        Clyde Companies, Inc. was organized as a holding company for shares of
common stock of Clyde, Geneva Rock, Utah Service and Beehive Insurance. On June
30, 1998, Clyde, Geneva Rock, Utah Service and Beehive Insurance were merged
(the "Merger") with and into the Company, and each issued and outstanding share
of common stock (except for shares owned by the Company) of Clyde, Geneva Rock,
Utah Service and Beehive Insurance was converted into, respectively, 33.93,
239.27, 43.43 and 4.33 shares of Common Stock of the Company. For a description
of the Merger and the transactions contemplated thereby, see the Company's Proxy
Statement/Prospectus dated May 13, 1998.

RESULTS OF OPERATIONS

        The Merger was accounted for using the purchase method of accounting.
The purchase method of accounting requires that consolidated results of
operations be reflected only from the date of the Merger, forward. Because the
Merger was consummated on June 30, 1998, consolidated operating results are
included in the Consolidated Statements of Earnings only for the three-month
period ended September 30, 1998. Prior to June 30, 1998, the Company recorded
only its equity in the net earnings of the Operating Companies. Since the
three-month period ended September 30, 1998 was the first quarter of
consolidated results of operations for the Company, it is not possible to
compare operating results for that period with operating results in prior
periods.

        During the nine-month period ended September 30, 1998, the Utah
construction markets continued to be strong and the economic climate in Utah
during the period was positive. Unemployment in Utah continued at the rate of
about 3.2%, which resulted in continuing labor shortages. Such labor shortages
exerted an upward pressure on wages which in turn increased costs, resulting in
lower profit margins.

        The construction market in Utah is seasonal, slowing down significantly
during winter months. Historically the third quarter of the year has been the
most profitable quarter of the year, due to favorable weather conditions, and
construction work normally begins to slow down in the fourth quarter, as the
weather becomes more unfavorable.

LIQUIDITY AND CAPITAL RESOURCES

        As explained in Note 2 to the Interim Financial Statements and under
Item 1 - Legal Proceedings, in connection with the Merger certain shareholders,
who collectively own the equivalent of 419,188 shares of Common Stock of the
Company, exercised their statutory dissenters' rights and demanded payment for
the fair value of the shares they held in the 


                                       10


<PAGE>   11
Operating Companies. The Operating Companies have paid the Dissenting
Shareholders an aggregate amount of $4,496,890, which is the amount the
Operating Companies determined to be the fair value of the shares held by the
Dissenting Shareholders on the date of the Merger. The Dissenting Shareholders
notified the Operating Companies that, in their opinion, the fair value of their
shares on the date of the Merger was greater than the amounts paid to them by
the Operating Companies, and demanded that the Operating Companies pay them
additional amounts for their shares, in the aggregate amount of approximately
$2,361,666. The Operating Companies have petitioned the Third Judicial District
Court of Salt Lake County to determine the fair value of the shares held by such
Dissenting Shareholders. The Company believes that the amounts paid to the
Dissenting Shareholders represented the fair value of the shares they held in
the Operating Companies on the date of the Merger, but there can be no assurance
that the Court will not determine that the fair value of the Operating Companies
was higher, and require that additional amounts be paid to the Dissenting
Shareholders. If the Company is required to pay substantial additional amounts
to the Dissenting Shareholders, the ability of the Company to pay dividends to
its shareholders and make capital expenditures may be adversely affected.

        Commencing in 1999, the Company will make funds available for the
redemption of a limited number of shares of its Common Stock pursuant to a Stock
Redemption Plan. The Stock Redemption Plan provides for a Redemption Fund (a)
for the years 1999 through 2003 in an amount which is greater than or equal to
7% and less than or equal to 15% of the net earnings of the Company (after
taxes) for the prior year and (b) for the years 2004 and thereafter an amount
which is greater than or equal to 5% and less than or equal to 10% of net
earnings of the Company (after taxes) for the prior year. Management believes
the limitation of the Redemption Fund to an amount not greater than 15% for the
years 1999 through 2003, and 10% for the years 2004 and thereafter, of the net
earnings of the Company (after taxes) for the prior year is a limitation
sufficient to protect the liquidity requirements of the Company and would not
adversely affect the Company's cash requirements.

INFLATION

        Inflation in the U.S. economy has been relatively moderate during the
last few years. Price increases for labor and materials, for the most part, have
kept pace with inflation. The low unemployment rate in Utah and the rapid
increase in the number of workers required in the construction industry in the
state has put increased pressure on the cost of labor. Labor contracts
negotiated in 1997 provide for increases in the 5% to 6% range per year through
the year 2000.

        The Company expects that inflation will affect cost of wages and
materials during the remainder of 1998, and that the current competitive
circumstances of the Utah market will preclude the Company from passing all of
such increases on to its customers. This circumstance may result in lower profit
margins for the Company in the remainder of 1998.

SEASONALITY

        Because the operations of the Company are located primarily in central
and northern Utah, the Company experiences significantly lower sales during the
winter months due to adverse weather conditions. Historically, the months of
November through March have shown 


                                       11

losses, with April through October being profitable months. The Company has
historically been able to deal with these seasonal variations in sales and has
established adequate cash reserves to address its liquidity requirements in the
winter months.
