                      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 six months ended June 30, 1998 should
        be read in conjunction with the Company's financial statements as of and
        for the year ended December 31, 1997, included in the Company's
        Registration Statement on Form S-4 dated May 13, 1998. The results of
        operations for the six months ended June 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 wholly-owned subsidiaries of the Company with
        W.W. Clyde & Co., Geneva Rock Products, Inc., Utah Service, Inc. and
        Beehive Insurance Agency, Inc. (the "Operating Companies") was
        consummated as of June 30, 1998 wherein 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 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 Company has registered the
        shares of Common Stock of the Company that were issued in the Merger.

        The purchase method of accounting requires consolidated results of
        operations only be reflected from the date of Merger forward. Because
        the Merger was consummated on June 30, 1998, the end of the reporting
        period, no consolidated operating results are included in the statements
        of earnings for the periods presented.

        The following unaudited pro forma consolidated data for the six months
        ended June 30, 1998 and the year ended June 30, 1997 presents the
        results of operations of the Company as if 


                                       8

        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.

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. ("CCI" or the "Company") formerly was a holding
company for shares of common stock of W.W. Clyde & Co., a Utah corporation
("Clyde"), Geneva Rock Products, Inc., a Utah corporation ("Geneva Rock"), Utah
Service, Inc., a Utah corporation ("Utah Service"), and Beehive Insurance
Agency, Inc., a Utah corporation ("Beehive Insurance"). CCI has no operations of
its own. On June 19, 1998, the shareholders of CCI, Clyde, Geneva Rock, Utah
Service and Beehive Insurance, approved the merger (the "Merger") of Clyde,
Geneva Rock, Utah Service and Beehive Insurance with and into wholly owned
subsidiaries of CCI. The Merger became effective as of June 30, 1998. Upon the
effective date of the Merger, each issued and outstanding share of Clyde Common
Stock, Geneva Rock Common Stock, Utah Service Common Stock and Beehive Insurance
Common Stock was converted into respectively, 33.93, 239.27, 43.43 and 4.33
shares of CCI Common Stock. For a description of the Merger and the transactions
contemplated thereby, see the Company's Proxy Statement/Prospectus dated May 13,
1998. Also, see Item 4 below.


RESULTS OF OPERATIONS

CCI

CCI's results of operations depend on the operating results of its two largest
subsidiaries, Clyde and Geneva Rock, and to a lesser extent, on Utah Service and
Beehive Insurance. The results of operations for Clyde and Geneva Rock are
discussed below.

Clyde

        Construction revenue for the six-month period ended June 30, 1998 was
$7,763,174 as compared to $3,851,063 for the six-month period ended June 30,
1997. The increase in construction revenue resulted in a net operating loss of
$97,782 for the 1998 interim period, as compared to a net operating loss of
$2,139,396 for the 1997 interim period. The increase in construction revenue was
largely attributable to the increased backlog of work under contract, and an
unusually mild winter. Backlog of work for the period ended June 30, 1998
increased to an estimated $12,412,273 compared to an estimated $6,255,083 for
the period ended June 30, 1997.

        The increase in construction revenue during the fist six months of 1998
resulted in an improved operating margin on construction revenue. In 1998 Clyde
experienced a 1.25% operating loss as compared to a 55.6% operating loss in
1997. The decrease in the operating loss 


                                       10


<PAGE>   11
was due in large part to the recovery of more of Clyde's fixed costs. The cost
of equipment and machinery owned and maintained by Clyde is a fixed cost which
represents a major component of Clyde's cost of construction. Utilizing this
equipment and machinery more during the six months ended June 30, 1998 allowed
Clyde to recover more of these expenses, thereby improving Clyde's operating
margin. Similarly, during the 1998 interim period the Company was able to
recover a greater percentage of its general and administrative expenses, which
also helped to improve Clyde's operating margin.

        For the reasons explained above, net earnings for the six-month period
ended June 30, 1998 was $506,526 compared with a net loss of $266,842 for the
comparable period in 1997.

        Other income of Clyde in the first six months of 1998 included a gain on
the sale of property and equipment in the amount of $222,700 compared to a gain
of $433,692 for the comparable period in 1997.

        Construction revenue for the three-month period ended June 30, 1998 was
$4,915,154 as compared to $3,049,055 for the three-month period ended June 30,
1997. The increase in construction revenue resulted in a net operating profit of
$61,720 for the 1998 three-month interim period, as compared to a net operating
loss of $478,720 for the 1997 three-month interim period. The increase in
construction revenue was largely attributable to the increased backlog of work
under contract, and an unusually mild winter.

        The increase in construction revenue during the three-month period ended
June 30, 1998 resulted in an improved operating margin on construction revenue.
For the three-month period ended June 30, 1998, Clyde experienced a 1.26%
operating profit as compared to a 15.7% operating loss for the comparable period
in 1997. This improvement was due in large part to the recovery of more of
Clyde's fixed costs and general and administrative expenses, as explained above.

        For the reasons discussed above, net profit for the three-month period
ended June 30, 1998 was $796,640 compared with a net profit of $704,841 for the
comparable period in 1997.

        Other income of Clyde in the three-month period ended June 30, 1998
included a gain on the sale of property and equipment in the amount of $30,200,
compared to a gain of $185,777 for the comparable period in 1997.


Geneva Rock

        Gross sales and contract income decreased by $507,508 or 1% for the
six-month period ended June 30, 1998 as compared to the comparable period in
1997. Gross sales and contract income for the three-month period ended June 30,
1998 and June 30, 1997 decreased $15,660 or less than -1/2 of 1%. This decrease
was primarily due to the slower sales of lumber, hardware, and masonry products
for both time periods by Geneva Rock's subsidiary, J&J Building Supply, Inc.
("J&J"), which is located in St. George, Utah. Geneva Rock earned operating
income of $1,426,834 for the first six months of 1998 as compared to operating
income of $4,343,684 for 


                                       11


<PAGE>   12
the same time period in 1997. For the three months ended June 30, 1998,
operating income decreased to $4,465,510 from $5,796,702 for the three months
ended June 30, 1997. This represents a $1,331,192 or 23% decrease. The reasons
for these decreases are explained below.

        The cost of sales and contracts increased by $2,766,484 or 6.0% for the
six-month period in 1998 over the same period in 1997, and $1,456,818 or 5.3%
for the three month period ending June 30, 1998, compared to the same period in
1997. Because of annual labor increases, both in wages and benefits, cost of
sales and contracts and gross margins were impacted. Labor and related costs
increased $933,825 or 7.4%, over the first six months of 1998 compared to 1997
and increased $426,902 or 5.6% for the three months of 1998 compared to 1997 .
Also, Geneva Rock employed more subcontractors in 1998 than in 1997 to perform
work on construction contracts resulting in an increase of $168,548 in
construction costs for the six months of 1998 compared to 1997 and a decrease in
the three month comparable period of $51,230. During the first six months of
1998, the cost of construction materials purchased by Geneva Rock increased by
$1,479,988 or 9.2% compared to 1997 and by $1,192,424 or 11.1% for the second
quarter of 1998 compared to 1997. In addition, selling prices of construction
materials produced by Geneva Rock such as ready mix concrete, sand, gravel, and
asphalt softened during the second quarter of 1998 and may continue through the
remainder of the year.

        General and administrative expenses decreased from $3,364,897 to
$3,007,737 for the first six months of 1998 compared to 1997 and from $1,919,075
to $1,777,789 for the three months ended June 30, 1998 compared to 1997. The
majority of the decrease is attributed to labor cutting measures at the
administrative level in J&J. These measures were initiated in the last quarter
of 1997 and first quarter of 1998. Other income increased by $219,013 for the
six months of 1998 compared to 1997 primarily due to Geneva Rock selling surplus
equipment earlier in 1998 than in 1997. This is a timing difference and will
correct itself in the third quarter of 1998.

        As a result of the above mentioned items, the net income for the six
month period ended June 30, 1998 was $1,216,954 as compared with a net income of
$2,963,654 for the comparable period in 1997, and for the three month second
quarter was $3,078,002 as compared to $3,766,640.

LIQUIDITY AND CAPITAL RESOURCES

CCI

        Commencing in 1999, CCI will make funds available for the redemption of
a limited number of shares of CCI 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 CCI (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 CCI (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 CCI (after taxes) for the
prior year is a limitation sufficient to protect the liquidity requirements of
CCI and would not adversely affect the Company's cash requirements.

Clyde

        Clyde's primary sources of liquidity have been funds generated by
operations and dividends received from Geneva Rock, in which Clyde had a 34.77%
interest prior to the Merger. Net cash used in operating activities was
approximately $2,245,639 and $1,271,437 for the six-month period ended June 30,
1998 and 1997, respectively. Net cash provided by operating activities is
primarily attributable to Clyde's income before depreciation and amortization
expense.


Geneva Rock

        Geneva Rock's primary source of liquidity has been funds generated by
operations. Net cash provided by operating activities was approximately
$7,873,013 and $4,853,145 for the six months ended June 30, 1998 and 1997,
respectively.

        The cash position of Geneva Rock increased to a June 30, 1998 balance of
$8,455,759 from a June 30, 1997 balance of $5,326,000. Cash increased in the
second quarter even though Geneva Rock reduced its debt by $940,461 by making an
annual payment on the note it issued to purchase J&J. This increase of cash
assets of Geneva Rock resulted from management's efforts to secure a strong cash
position for general corporate purposes and for possible future business
expansion.

        In addition to substantial cash assets on June 30, 1998 and June 30,
1997, Geneva Rock had a line of credit with First Security Bank of Utah, N.A.
Geneva Rock's unsecured line of credit with First Security was $2,000,000 as of
June 30, 1998. Geneva Rock's subsidiary, J & J has an unsecured line of credit
with First Security of $1,500,000. As of June 30, 1998, neither Geneva Rock nor
J & J had any outstanding amounts on the lines of credit.

        Management of Geneva Rock has determined that to maintain and increase
market share, Geneva Rock needs to continually modernize and upgrade its fleet
and equipment. Geneva Rock 


                                       13


<PAGE>   14
has received approval from its Board of Directors to purchase and/or lease
equipment that was scheduled to be delivered in the first two quarters of 1998
in the amount $11,290,000 and has taken delivery of $9,747,834 worth of
equipment as of June 30, 1998. The remaining amount of approved equipment has
been delayed to allow management to determine if the economy will remain strong
enough to justify the acquisitions. Management of Geneva Rock believes that the
company's current cash reserves and future sales revenues will be adequate to
service Geneva Rock's commitments for the purchase and lease payments to be made
on this equipment, without impairing Geneva Rock's liquidity 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.

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

SEASONALITY

        Because the operations of Clyde and Geneva Rock are located primarily in
central and northern Utah, Clyde and Geneva Rock experience significantly lower
sales during the winter months due to adverse weather conditions. Historically,
the months of November through March have shown losses for Clyde and Geneva
Rock, with April through October being profitable months. Clyde and Geneva Rock
have historically dealt well with these seasonal variations in sales and has
established adequate reserves to address the liquidity requirements of Clyde and
Geneva Rock in the winter months.
