PART I - FINANCIAL INFORMATION

The condensed consolidated financial statements included herein have been
prepared by Building Materials Holding Corporation ("BMHC" or the "Company")on a
consolidated basis, without audit, pursuant to the rules and regulations of the
Securities and Exchange Commission.  BMHC was formed on September 23, 1997 in a
holding company reorganization in which BMC West Corporation, the former
registrant, became a wholly owned subsidiary of BMHC.  This new structure was
adopted to centralize certain administrative functions as the Company expands
its participation in the consolidation of the contractor focused building
materials distribution industry.  All references to the "Company" will mean BMHC
on a consolidated basis if referring to periods after September 23, 1997, or BMC
West Corporation for all preceding periods. 

In the opinion of management, all adjustments necessary to present fairly the
financial results for the periods presented have been included in management's
discussion and analysis.  The adjustments made were of a normal, recurring
nature.  Certain information and footnote disclosures normally included in the
consolidated financial statements have been condensed or omitted pursuant to the
rules and regulations of the Securities and Exchange Commission, although the
Company believes that the disclosures are adequate to make the information
presented not misleading.  It is recommended that these condensed consolidated
financial statements be read in conjunction with the audited consolidated
financial statements and notes thereto included in the Company's 1997 Annual
Report.

The condensed consolidated results of operations for the periods presented are
not necessarily indicative of the results that might be expected for the fiscal
year.

4.   ACCQISITIONS
     In the second quarter of 1998, the Company completed five acquisitions
     consisting of eight locations, six of which have value-added facilities
     located in Montana, Oregon, Texas and Washington.  The total consideration
     given was $15.6 million consisting of $11.5 million in cash, 299,343 shares
     of common stock valued at $4.0 million and other assumed operating
     liabilities of $81,000.  For purposes of the Statements of Cash Flows,
     those portions of the acquisitions completed by payment of the Company's
     common stock or through the assumption of operating liabilities have been
     treated as non-cash transactions.

5.   START-UP COSTS
     On April 3, 1998, the AICPA issued Statement of Position (SOP)98-5,
     REPORTING ON THE COSTS OF START-UP ACTIVITIES.  This SOP provides guidance
     on the financial reporting of start-up and organization costs.  The SOP
     requires costs of start-up activities and organization costs to be expensed
     as incurred.  This SOP is effective for financial statements with fiscal
     years beginning after December 15, 1998 and earlier application is
     encouraged.  The Company adopted this SOP during the second quarter of
     1998.  The resulting impact on the Company's consolidated  results of
     operations and financial condition was immaterial.


6.   NEW ACCOUNTING PRONOUNCEMENT
     In June, 1998, the Financial Accounting Standards Board issued Statement of
     Financial Accounting Standards No. 133, ACCOUNTING FOR DERIVATIVE
     INSTRUMENTS AND HEDGING ACTIVITIES.  The Statement establishes accounting
     and reporting standards requiring derivative instruments (including certain
     derivative instruments embedded in other contracts) be recorded in the
     balance sheet as either an asset or liability measured at its fair value. 
     This Statement is effective for fiscal quarters of fiscal years beginning
     after June 15, 1999.  The Company plans to adopt this Statement in the
     first quarter of 2000.  The Company is still in process of reviewing this
     Statement, however, given that the Company does not utilize derivative
     instruments, adoption of this Statement is not expected to have an impact
     on the Company's consolidated results of operations or financial condition.

SECOND QUARTER OF 1998 COMPARED TO THE SECOND QUARTER OF 1997

Net sales for the three months ended June 30, 1998 were $226.0 million up 18.6%
from the second quarter of 1997 when sales were $190.6 million.  The largest
portion of this increase was due to acquisitions contributing $26.6 million. 
The increase in net sales also resulted from a 5.7% increase over the second
quarter of 1997 in sales at facilities that operated for at least two months in
both the second quarter of 1997 and the second quarter of 1998 ("same-store
sales").  Sales increased despite overall price deflation of 3.2%, primarily
attributable to commodity wood product prices.  Adjusting for the price
deflation, real same-store sales were approximately 8.9% over the year-ago
quarter.

Gross profit as a percentage of sales increased to 24.2% in the second quarter
of 1998 from 22.8% in the second quarter of 1997, primarily as a result of on-
going efforts by the Company to improve margins through its increased focus on

                                      10


<PAGE>


value-added products, such as roof trusses, pre-hung doors, millwork, and 
pre-assembled windows.

Selling, general and administrative (SG&A) expense, was $44.5 million in the
second quarter of 1998 as compared to $35.8 million in 1997, and increased as a
percentage of net sales from 18.8% in 1997 to 19.7% in 1998.  The Company
attributes this partially to increases in value-added sales that carry higher
SG&A expenses and integrating new operating locations that were not included in
the comparable period.

Interest expense of $2.7 million in the second quarter of 1998 increased from
$2.4 million in the same period of 1997, primarily due to increased borrowings
under the Company's revolving line of credit to support higher working capital
as a result of increased sales and acquisitions made during the previous 12
months.

Income taxes were provided at estimated annual effective tax rates of 39.5% for
the periods ended June 30, 1998 and June 30, 1997.

As a result of the foregoing factors, net income increased by $1.3 million, or
37.4% to $4.8 million, or 2.1% of net sales in the second quarter of 1998, as
compared to $3.5 million, or 1.8% of net sales, in the second quarter of 1997.

FIRST SIX MONTHS OF 1998 COMPARED WITH THE FIRST SIX MONTHS OF 1997

Net sales for the six months ended June 30, 1998 were $409.6 million up 21.4%
from the first half of 1997 when sales were $337.4 million. The largest portion
of this increase was due to acquisitions contributing $47.5 million.   The
increase in net sales also resulted from an increase of 8.7% in same-store
sales, over the first six months of 1997. Sales in the 1998 period were
negatively affected by lower commodity wood product prices.  The price decrease
contributed to an overall price deflator of 3.4%, the effect of which decreased
sales by approximately $11.4 million.  Excluding price deflation, same-store
sales increased 12.1%.

<PAGE>

Gross profit as a percentage of sales improved to 24.1% in the first half of
1998 from 23.1% in the first six months of 1997, primarily as a result of on
going efforts by the Company to improve margins through its increased focus on
value-added products, such as roof trusses, pre-hung doors, millwork and 
pre-assembled windows.

Selling, general and administrative (SG&A) expense, was $85.0 million in the
first six months of 1998 as compared to $67.7 million in 1997, and increased as
a percentage of net sales to 20.7% in 1998 from 20.1% in 1997. The Company
attributes this partially to increases in value-added sales that carry higher
SG&A expenses and integrating new operating locations that were not included in
the comparable period.

Interest expense increased to $5.2 million in the first six months of 1998 from
$4.5 million in the same period of 1997, primarily due to increased borrowings
under the Company's revolving line of credit to support higher working capital
as a result of increased sales and acquisitions made during the previous 12
months.

Income taxes were provided at estimated annual effective tax rates of 39.5% for
the six month periods ended June 30, 1998 and June 30, 1997.  

As a result of the foregoing factors, net income increased by $1.7 million, or
43.1% to $5.6 million, or 1.4% of net sales in the first half of 1998, as
compared to $3.9 million, or 1.2% of net sales, in the first six months of 1997.

LIQUIDITY AND CAPITAL RESOURCES

At June 30, 1998 the Company had $126.6 million of long-term debt outstanding,
consisting of $78.7 million of term borrowings under fixed rate notes, and $47.9
million of variable rate debt under the revolving credit agreement.

In the first half of 1998, the Company generated $9.3 million of cash from
operating activities.  Working capital increased from $118.6 million at 
December 31, 1997 to $128.3 million at June 30, 1998, due primarily to 

                                      12


<PAGE>

increased sales and acquisitions made during the previous 12 months and due to 
the seasonality in the Company's accounts receivable and inventories.

Based on its ability to generate cash from operations and the available
borrowing capacity at June 30, 1998 of $22.1 million under the revolving credit
agreement (availability of which is subject to the satisfaction of certain
customary borrowing conditions), the Company believes it will have sufficient
funds to meet its currently anticipated requirements.


YEAR 2000 SYSTEM ISSUE

The Company continues to review its financial and operating systems with respect
to the Year 2000 issue.  The Company is in the process of making normal upgrades
and modifications to its significant financial and operating systems, including
both hardware and software components.  The upgrades are designed, among other
things, to address the Year 2000 issue, and are not presently expected to result
in a material incremental expense to the Company.  Based on the  Company's
progress to date in addressing its significant operating and financial
applications, the Company does not currently anticipate any material disruption
in its operations as a result of the Year 2000 issue.

PART II -- OTHER INFORMATION

ITEM 1.     LEGAL PROCEEDINGS
            The Company is involved in litigation and administrative
            proceedings primarily arising in the normal course of its
            business.  In the opinion of management, the Company's recovery,
            if any, or the Company's liability, if any, under any pending
            litigation or administrative proceedings would not materially
            affect its financial condition or operations.
