Notes to Consolidated Financial Statements

1. Summary of Significant Accounting Policies

Nature of operations

Building Materials Holding Corporation, a Delaware corporation (“BMC”), is one of the nation’s leading providers of lumber and building materials, doors and millwork, trusses and components and construction services for professional homebuilders and contractors. BMC is privately owned and headquartered in Atlanta, Georgia. BMC employs approximately 6,500 people and operates in 12 states primarily in the western and southeastern United States and Texas. BMC provides building products and construction services in 11 of the top 25 single-family construction markets in the United States, based on National Association of Home Builders (NAHB) building permit activity data for the nine months ended September 30, 2015.

Principles of consolidation

These unaudited consolidated financial statements include BMC’s accounts and subsidiaries. All significant intercompany balances and transactions are eliminated.

Basis of presentation

These unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). BMC’s interim results are not necessarily indicative of results that may be expected for the full year due to, among other things, the seasonal nature of BMC’s business. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the accompanying notes included in BMC’s 2014 Annual Report.

These unaudited consolidated financial statements have not been audited by BMC’s independent auditors. However, in the opinion of management, all adjustments, including those of a normal and recurring nature, necessary to present fairly the results for the periods have been included. The preparation of these unaudited consolidated financial statements requires estimates and assumptions. Actual results may differ from those estimates.

The consolidated balance sheet as of December 31, 2014 has been derived from the audited consolidated financial statements as of that date, however, certain information and disclosures normally included in annual consolidated financial statements prepared in accordance with GAAP have been condensed or omitted.

For a description of BMC’s significant accounting policies, see Note 2, Summary of Significant Accounting Policies, of the Notes to the Consolidated Financial Statements in Item 8 of BMC’s 2014 Annual Report.

Construction services

Revenue recognized using the percentage-of-completion method for both the three and nine months ended September 30, 2015 and September 30, 2014 represented 91% and 94%, respectively, of the total revenue for construction services for each of the respective periods.

Estimated losses on uncompleted contracts and changes in contract estimates

The reserve for these estimated losses was $0.2 million at September 30, 2015 and $0.1 million at September 30, 2014. The activity for the three and nine months ended September 30, 2015 and September 30, 2014, respectively, was not significant.

Shipping and handling

Shipping and handling costs for building products are included as a component of selling, general and administrative expenses and were $21.7 million for the three months ended September 30, 2015 and $16.2 million for the three months ended September 30, 2014. Additionally, shipping and handling costs were $53.9 million for the nine months ended September 30, 2015 and $45.2 million for the nine months ended September 30, 2014.

4

Property and equipment

Property and equipment is net of accumulated depreciation of $76.9 million and $65.3 million as of September 30, 2015 and December 31, 2014, respectively.

Reclassifications

Certain amounts previously reported have been reclassified to simplify presentation. These reclassifications did not affect previously reported results of operations, financial position, or cash flows.

New and recently adopted accounting principles

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers. This accounting principle requires revenue to be recognized based on the performance obligations in the contract with the customer. This accounting principle also requires quantitative disclosure of contracts by categories that depict how the nature, timing and uncertainty of revenue and cash flows are affected by economic factors and qualitative disclosures regarding transaction prices allocated to remaining performance obligations and their timing. For public entities, this accounting principle is effective for annual reporting periods beginning after December 15, 2017, and interim reporting periods within those annual periods. For all other entities, this accounting principle will be effective for annual reporting periods beginning after December 15, 2018, and interim periods within annual periods beginning after December 15, 2019. Early application will be permitted for all entities, but not before annual periods beginning after December 15, 2016.

The standard permits the use of either the retrospective or cumulative effect transition method. BMC has not selected a transition method and BMC is evaluating the changes this accounting principle will have on its results of operations, financial position or cash flows.

In April 2015, the FASB issued Accounting Standards Update 2015-03, Simplifying the Presentation of Debt Issuance Costs. This accounting principle requires debt issuance costs be presented in the balance sheet as a direct deduction from the related debt liability rather than as an asset. For public entities, this accounting principle is effective for annual reporting periods and interim periods within those annual accounting periods beginning after December 15, 2015. For all other entities, this guidance is effective for accounting periods beginning after December 15, 2016. Early adoption is permitted for financial statements that have not been previously issued. BMC has chosen to adopt this accounting principle for annual reporting periods and interim periods within those annual accounting periods beginning after December 15, 2015.

In April 2015, the FASB issued Accounting Standards Update No. 2015-05, Customer's Accounting for Fees Paid in a Cloud Computing Arrangement. This accounting principle provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The guidance will not change GAAP for a customer's accounting for service contracts. The guidance is effective for annual and interim periods beginning after December 15, 2015. For all other entities, the standard is effective for annual periods beginning after December 15, 2015, and interim periods in fiscal years beginning after December 15, 2016. Early adoption is permitted for all entities.

In July 2015, the FASB issued Accounting Standards Update 2015-11, Measurement of Inventory (ASU 2015-11). ASU 2015-11 changes the measurement principle for inventory from the lower of cost or market to lower of cost and net realizable value for entities that measure inventory using a method other than last-in, first-out (LIFO) or the retail inventory method (e.g., first-in, first-out (FIFO), average cost). The ASU 2015-11 also eliminates the requirement for these entities to consider replacement cost or net realizable value less an approximately normal profit margin when measuring inventory. For public entities, this accounting principle is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual reporting periods. For all other entities, this guidance is effective for annual and interim reporting periods beginning after December 15, 2016, and interim periods beginning after December 15, 2017. Early adoption is permitted. BMC is evaluating the changes this accounting principle will have on its results of operations, financial position or cash flows.

In August 2015, the FASB issued Accounting Standards Update No. 2015-15, Interest - Imputation of Interest: Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting (“ASU 2015-15”). ASU 2015-15 clarifies the treatment of debt issuance costs for line-of-credit arrangements, which was not addressed in Accounting Standards Update

5

2015-03, Simplifying the Presentation of Debt Issuance Costs. ASU 2015-15 clarifies that the SEC staff would not object to an entity deferring and presenting debt issuance costs related to a line-of-credit arrangement as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of such arrangement, regardless of whether there are any outstanding borrowings under the line-of-credit arrangement. ASU 2015-15 is effective for the public business entities for the fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. It is effective for all other entities for fiscal years beginning after December 15, 2015, and interim periods within fiscal years after December 15, 2016. Early adoption is permitted for all entities for financial statements that have not been previously issued. BMC is evaluating the impact of the standard on its financial statements.

In September 2015, the FASB issued Accounting Standards Update 2015-16, Simplifying the Accounting for Measurement-Period Adjustments. This update requires an acquirer to recognize adjustments to provisional amounts that are identified during the measurement period, in the reporting period in which the adjustment amounts are determined. The amendments in this update also require an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. This update is effective for all public companies for annual and interim periods beginning after December 15, 2015. For all other entities, the update is effective for annual periods beginning December 15, 2016, and interim periods beginning after December 15, 2017. Early adoption is permitted if financial statements have not been issued. BMC will be adopting this update for annual and interim periods beginning after December 15, 2015.

Other new accounting and disclosure requirements have been issued by accounting authorities; however, these requirements are not applicable to these financial statements. There have been no recently adopted accounting or disclosure requirements and, as a result, there has been no impact on BMC’s results of operations, financial position or cash flows.

Subsequent events

In addition, BMC has evaluated events and transactions subsequent to September 30, 2015 through November 18, 2015, the date these consolidated financial statements were issued.

2. Merger Agreement with Stock Building Supply Holdings, Inc.

On June 2, 2015, BMC and Stock Building Supply Holdings, Inc., a Delaware corporation (“SBS”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which BMC, subject to certain conditions, will be merged with and into SBS, with SBS surviving the merger (the “Merger”).

Under the terms of the Merger Agreement, which has been unanimously approved by the board of directors of each company, BMC stockholders will receive 0.5231 newly issued SBS shares for each BMC share. Upon the closing of the transaction, BMC stockholders will own approximately 60% of the merged entity, with stockholders of SBS immediately prior to the closing of the Merger owning approximately 40%. The transaction is structured to be tax-free to the stockholders of both companies, and is expected to close in the fourth quarter of 2015, subject to approval by the stockholders of SBS and BMC.

The Merger Agreement contains customary representations and warranties from both SBS and BMC, and each party has agreed to customary covenants, including, among others, covenants relating to the conduct of its business during the interim period between the execution of the Merger Agreement and the effective time of the Merger. In addition, SBS and BMC have made customary non-solicitation covenants prohibiting each from: (i) soliciting, providing non-public information or engaging or participating in any discussions or negotiations concerning proposals relating to alternative business combination transactions, or (ii) entering into an acquisition agreement in connection with such an alternative business combination transaction, in each case, except as permitted under the Merger Agreement.

The Merger Agreement contains certain termination rights for SBS and BMC, including in the event that: (i) the Merger is not consummated on or before December 31, 2015, (ii) the approval of the stockholders of SBS is not obtained at a stockholder meeting, (iii) the approval of the stockholders of BMC is not obtained pursuant to written consent, (iv) the other party’s board of directors changes its recommendation to its stockholders due to an intervening event, or (v) either SBS or BMC terminates the Merger Agreement to enter into a binding agreement providing for a superior alternative transaction. The Merger Agreement further provides that, upon termination of the Merger Agreement under specified circumstances, including in connection with a change in the recommendation of the board of directors of SBS or BMC or a termination of the Merger Agreement by SBS or BMC to enter into a binding agreement providing for a superior alternative transaction, SBS or BMC, as the case may be, will pay to the other party a termination fee. The termination fee payable by SBS equals $15.7 million in cash. The termination fee payable by BMC equals $23.6 million in cash.

6

BMC incurred merger and integration costs of $1.0 million and $4.0 million for the three and nine months ended September 30, 2015, respectively.

3. Acquisitions

BMC allocates the purchase price to the estimated fair values of the assets acquired and liabilities assumed as of the date of the acquisition. The market approach, which indicates value based on available market pricing for comparable assets, is utilized to estimate the fair value of inventory and property and equipment. The income approach, which indicates value based on the present value of future cash flows, is primarily used to value the intangible assets. The cost approach, which estimates values by determining the current cost of replacing an asset with another of equivalent utility, is used, as appropriate, for certain assets for which the market and income approaches could not be applied due to the nature of the asset.

VNS Corporation (VNS)

On May 1, 2015, BMC completed the acquisition of Vidalia, Georgia-based VNS Corporation (“VNS”), enabling BMC to expand its product offerings into the southeastern United States. BMC funded the transaction through the use of available cash and borrowings under the Revolver. The preliminary purchase price was $47.0 million, net of $2.3 million of acquired cash. The acquisition was accounted for using the acquisition method of accounting under ASC 805, Business Combinations (ASC 805).

The preliminary allocation of fair value to assets and liabilities acquired on May 1, 2015 was as follows (thousands):

Cash	$	2,344
Receivables	19,594
Inventory	10,665
Deferred income taxes	217
Prepaid and other current assets	917
Current assets	$	33,737
Property and equipment, net	11,668
Other intangibles	12,450
Goodwill	7,837
Other long-term assets	59
Total assets	$	65,751
Accounts payable and other accrued liabilities	11,353
Current liabilities	$	11,353
Deferred income taxes	5,096
Total liabilities	$	16,449

The preliminary purchase price allocation resulted in goodwill of $7.8 million, which is not deductible for income tax purposes. Goodwill consists of expected synergies and cost savings from excess purchase price over identifiable intangible net assets, as well as intangible assets that do not qualify for separate recognition, such as assembled workforce. Other intangible assets consist of customer relationships and trade names. These are expected to be amortized over 10 and 2 years, respectively.

The purchase price allocation is preliminary and subject to revision. At this time, except for the items noted below, we do not expect material changes to the value of the assets acquired or liabilities assumed in conjunction with the VNS acquisition. Specifically, the following assets and liabilities are subject to change:

• Intangible customer relationships and trade names

• Deferred income tax assets and liabilities

• Working capital adjustments

7

As BMC receives additional information during the measurement period, these assets and liabilities may be adjusted.

VNS recorded sales of $35.4 million, gross profit of $8.7 million and net income of $1.6 million for the three months ended September 30, 2015, and sales of $60.1 million, gross profit of $14.0 million and net income of $2.1 million for the period beginning May 1, 2015 through September 30, 2015.

Robert Bowden Inc. (RBI)

On September 1, 2015, BMC purchased certain assets (excluding cash) and assumed certain liabilities of Marietta, Georgia-based Robert Bowden Inc. (“RBI”) for an initial purchase price of $102.7 million in cash (subject to certain adjustments). RBI has three locations in the Atlanta, Georgia area, including its manufacturing facility in Marietta. RBI sells millwork and window products to homebuilders and residential contractors primarily in the Atlanta metro market. BMC funded the transaction through borrowings under the Revolver. The acquisition was accounted for using the acquisition method of accounting under ASC 805.

The preliminary allocation of fair value to assets and liabilities acquired on September 1, 2015 was as follows (thousands):

Receivables	$	8,913
Inventory	6,702
Prepaid and other current assets	122
Current assets	$	15,737
Property and equipment, net	5,524
Other intangibles	39,700
Goodwill	44,960
Total assets	$	105,921
Accounts payable and other accrued liabilities	3,218
Total liabilities	$	3,218

The preliminary purchase price allocation resulted in goodwill of $45.0 million, which is deductible for income tax purposes. Goodwill consists of expected synergies and cost savings from excess purchase price over identifiable intangible net assets, as well as intangible assets that do not qualify for separate recognition, such as assembled workforce. Other intangible assets consist of customer relationships and non-compete agreements. These are expected to be amortized over 10 and 3 years, respectively.

The purchase price allocation is preliminary and subject to revision. At this time, except for the items noted below, we do not expect material changes to the value of the assets acquired or liabilities assumed in conjunction with the RBI acquisition. Specifically, the following assets and liabilities are subject to change:

• Intangible customer relationships and non-compete agreements

• Working capital adjustments

As BMC receives additional information during the measurement period, these assets and liabilities may be adjusted.

RBI recorded sales of $7.3 million, gross profit of $2.6 million and net income of $0.6 million for the month of September 2015. These results are included in BMC’s unaudited consolidated statement of operations for three and nine months ended September 30, 2015.

4. Insurance Deductible Reserves

BMC retains the risk for workers compensation, automobile, general liability and construction defect claims up to the insurance deductibles. Insurance deductibles range from $0.5 million to $2.0 million per claim. Claims in excess of insurance deductibles are insured with third-party insurance providers.

The estimated cost of these claims up to the insurance deductibles is based on actuarial methods as provided by a third-party actuary. Estimated costs of these claims are subject to the nature and frequency of claims, medical cost inflation and changes in

8

the insurance deductibles of the applicable insurance policies. Actual loss experience may differ from the actuarial assumptions. Revisions to insurance deductible reserves for estimated claims are recognized in the period such revisions are known and can be reasonably estimated.

Insurance deductible reserves are not discounted. These claims are expected to be paid over the next five years, however, some claim payments may be longer. Insurance deductible reserves are as follows (thousands):

	September 30, 2015						December 31, 2014
	Current		Long-term		Total		Current		Long-term		Total
Claims prior to 2010
Workers compensation	$	844	$	2,832	$	3,676	$	1,176	$	3,410	$	4,586

(1) In January 2015, BMC entered into a retroactive reinsurance contract to transfer the risk of loss for workers compensation claims incurred for 2006 through 2011 to a reinsurer.

Retroactive reinsurance contract

In January 2015, BMC entered into a retroactive reinsurance contract to transfer the risk of loss of certain insurance deductible reserves for workers compensation claims incurred to another insurance provider, a reinsurer. BMC paid $11.1 million to the reinsurer to assume $8.3 million insurance deductible reserves for workers compensation claims incurred for 2006 through 2011 as of January 2015. Pursuant to the reinsurance contract, the reinsurer is obligated to pay an aggregate maximum of $17.5 million for these claims whereas claims in excess of this aggregate maximum, if any, will be BMC’s obligation.

The $11.1 million payment made to the reinsurer exceeded BMC’s $8.3 million insurance deductible reserve for these claims. Accordingly, BMC recorded an $8.3 million reinsurance receivable as an asset in BMC’s consolidated balance sheet which matches the liability for these claims and recognized $1.7 million expense net of tax in BMC’s unaudited consolidated statement of operations.

Changes in these claims are recorded in BMC’s consolidated balance sheet as an increase or decrease in the insurance deductible reserves and corresponding decrease or increase in the reinsurance receivable. The reinsurance receivable was $6.8 million as of September 30, 2015.

BMC regularly monitors the financial condition of its reinsurer under reinsurance contracts to minimize its exposure to significant losses from reinsurer insolvency. BMC does not believe it is exposed to any significant credit risk.

Letters of credit

BMC provides letters of credit to guarantee payment to BMC’s third-party insurance providers for these claims as well as cash collateral for certain of these letters of credit as follows (thousands):

	September 30, 2015								December 31, 2014
			Collateral								Collateral

(1) As a result of the reinsurance transaction, in January 2015, letters of credit decreased $20.0 million and BMC reduced restricted cash $21.0 million.

Letters of credit are not required to be cash collateralized; however, uncollateralized letters of credit under BMC’s Revolver agreement reduce its Revolver availability. Cash may be retained in a separate bank account at 105% of the related claims.

5. Debt

Long-term debt consists of the following (thousands):

							Effective Interest Rate
							2015		2014

Revolver

In June 2015, BMC entered into an amendment to increase availability under the Revolver from $125.0 million to $215.0 million, with no changes to its maturity. The Revolver was amended in anticipation of BMC’s increasing working capital requirements and the purchases of VNS and RBI. BMC incurred loan costs of $0.9 million as a result of the amendment. The loan cost will be amortized over the remaining term of the Revolver.

The $215.0 million Revolver is subject to availability and matures March 2018. The Revolver is secured by a first priority lien on certain working capital and may consist of both LIBOR and Prime based borrowings.

Variable interest rates are based on average availability for the prior quarter and are LIBOR plus 1.5% to 2.0% or Prime plus 0.50% to 1.0% based on the Revolver availability, plus applicable margin. The variable interest rate in effect at September 30, 2015 was LIBOR plus 1.5% or Prime plus 0.5%. The commitment fee for the unused portion ranged from 0.25% to 0.375%

10

based on average Revolver usage prior to the amendment. Effective June 2015, the commitment fee is 0.25%. Interest is paid monthly.

Revolver availability is subject to a borrowing base and is reduced by outstanding borrowings and letters of credit. The borrowing base generally includes 85% of certain accounts receivable plus 70% of certain inventory, minus an amount equal to three months of rent payable on all leased real property and warehouses where inventory is located. BMC’s borrowing base ranged from $56.9 million to $145.3 million during the three months ended September 30, 2015.

As of September 30, 2015, there was $105.5 million outstanding under BMC’s Revolver and availability was $56.9 million. As of December 31, 2014, there were no amounts outstanding under the Revolver and availability was $89.0 million.

Letters of credit under the Revolver agreement guarantee payment to third-party insurance providers for claims after January 2010 and guarantee construction performance and certain inventory purchases. These letters of credit were $35.3 million as of September 30, 2015 and $31.1 million as of December 31, 2014. The interest rate ranges from 0.75% to 1.25% plus a fronting fee of 0.125%. Interest is paid monthly.

Senior Secured Notes

The Notes mature in September 2018. The Notes are secured by a first priority lien on certain property and equipment and a subordinate lien on certain assets. The Notes are guaranteed by each of BMC’s subsidiaries. As of September 30, 2015, there was $250.0 million of principal outstanding under the Notes.

The interest rate is fixed at 9.0% and is payable semiannually in March and September.

BMC may redeem the Notes at a redemption price of 106.75% beginning September 2015 declining to 103.375% beginning September 2016. Redemption prices are reduced to par value in September 2017.

In connection with the September 2013 refinancing, BMC incurred:

• $10.8 million deferred loan costs; and

◦ $1.2 million original issue discount.

These costs are amortized over the remaining term of the Notes and recorded as interest expense in the unaudited consolidated statement of operations. Amortization expense for deferred loan costs was $0.6 million and $1.8 million for the three and nine months ended September 30, 2015 and $0.6 million and $1.7 million for the three and nine months ended September 30, 2014. Amortization expense for original issue discount was $0.2 million for the nine months ended September 30, 2015 and $0.2 million for the nine months ended September 30, 2014. Amortization expense for original issue discount for the three months ended September 30, 2015 and 2014, respectively, was not material.

Letters of credit facility

Letters of credit under the Letter of Credit Facility guarantee payment to third-party insurance providers for claims prior to January 2010. These letters of credit were $14.4 million as of September 30, 2015 and $34.4 million as of December 31, 2014. The interest rate or fee is 0.75% plus a fronting fee of 1.25%. Interest is paid monthly.

Cash may be retained in a separate bank account at 105% collateral. Restricted cash used as collateral on these letters of credit was $15.1 million as of September 30, 2015 and $36.1 million as of December 31, 2014.

Other

Other long-term debt consists of $7.1 million term notes secured by delivery and handling equipment with various maturities through April 2019 and a $0.5 million term note secured by real property with a maturity of March 2021. The interest rates range from 4.6% to 8.4%. Interest is paid monthly.

Covenants and maturities

The Revolver agreement and indenture for the Notes restrict BMC’s ability to incur restricted payments such as additional indebtedness, create or incur liens, enter into transactions with affiliates, enter into agreements restricting BMC’s subsidiaries ability to pay dividends, make loans or investments, pay dividends, repurchase shares, enter into mergers or acquisitions, use

11

proceeds from equity offerings and sell assets. Compliance with a minimum fixed charge coverage ratio is required before and after these restricted payments as well as in the event Revolver availability is less than $20.0 million. Operating results, particularly income from operations, is a primary factor for this covenant, and BMC’s ability to comply with this covenant depends on its operating performance. As of September 30,2015, our Revolver availability was in excess of $20.0 million and a minimum fixed charge coverage ratio was not required.

Scheduled maturities of long-term debt were as follows (thousands):

2015	$	1,401
2016	2,778
2017	1,970
2018	356,744
2019	145

	$	363,167

6. Headquarters Relocation

In May 2014, BMC announced its plan to relocate its headquarters from Boise, Idaho to Atlanta, Georgia. The decision to relocate reflects the need to fill key management positions to support growth and expand geographically and this requires a more central location with a larger population base and fully accessible air travel.

The relocation will occur in phases over time with the executive team moving immediately. The relocation is expected to be substantially complete no later than December 2016.

BMC expects to incur the following costs in connection with this relocation (thousands):

	Total		Recognized through September 30, 2015		Remaining Costs to be Recognized
Cash charges
Employee:
Retention	$	5,000	$	2,590	$	2,410
Severance	1,500		670		830

Other	—		—		—			—
	$	1,490	$	2,811	$	(1,732	)	$	2,569

Employee retention charges are recognized ratably over the required service periods. Severance, recruiting, relocation and professional fees are recognized in the period incurred. Cash and non-cash charges are recognized in selling, general and administrative expenses. BMC expects the remaining costs to be incurred through 2016.

These costs may change as management executes the approved plan. Revisions to these estimated costs will be recognized in the period such revisions become known.

7. Income Taxes

BMC’s estimated annual effective tax rate is used to allocate expected annual income tax expense to interim periods. Income tax (expense) benefit and effective rates were as follows (thousands):

	Three Months Ended September 30,								Nine Months Ended September 30,
	2015				2014				2015				2014
				Effective Rate				Effective Rate				Effective Rate			Effective Rate
Income tax (expense) benefit	$	(4,168	)	(50.7)%	$	(4,935	)	(39.6)%	$	(3,299	)	(55.8)%	$	66,809	287.1%

BMC’s effective tax rate for the nine months ending September 30, 2015 was 55.8% and comprised of federal and state income tax rates, adjusted for projected permanent differences.

BMC recognized income tax expense of $3.3 million and income tax benefit of $66.8 million for the nine months ended September 30, 2015 and September 30, 2014, respectively. The income tax benefit of $66.8 million in 2014 was recognized at the time of reversal of the valuation allowance, a discrete item on BMC’s deferred tax assets, offset by income tax expense for federal and certain states for the nine months ended September 30, 2014.

No valuation allowance was recorded as of September 30, 2015 or December 31, 2014. BMC evaluated positive and negative evidence to assess whether sufficient future taxable income would be generated to realize the existing deferred tax assets as of September 30, 2015 and December 31, 2014. As part of its evaluation, BMC considered its growth over the preceding few years both organically and through acquisitions, with revenues exceeding $1.3 billion in 2014 and $1.2 billion in 2013, and the consolidated profit before tax in 2013 and 2014. BMC also considered the history of its cumulative pre-tax income since 2012, adjusted for permanent items and taxable income in 2013 and 2014, in its assessment for determining a need for valuation allowance. Over the past three years, taxable income before net operating loss deductions has differed from pre-tax income due primarily to timing differences of deductions related to depreciation of fixed assets and amortization of intangibles.

Factors contributing additional positive evidence to support no valuation allowance as of September 30, 2015 included: (i) $28.5 million in pre-tax income for the full year ended December 31, 2014; (ii) cumulative pre-tax income for the three years

13

ended September 30, 2015; (iii) the May 1, 2015 acquisition of VNS, which had no prior history of net operating loss or unused tax credit carryforwards under federal and state tax law; (iv) the September 1, 2015 acquisition of RBI, an entity with three years of consistent pre-tax income; (v) steadily improving economic indicators such as permit activity, single-family starts and completions in BMC’s markets; (vi) projected future taxable income based on positive financial indicators compared to the prior year; and (vii) no history of expiring tax attributes. Contributing to projected future taxable income were increases in sales, gross margin and sales backlog, as well as external factors, such as growth in home sales and prices and macroeconomic reports indicating falling unemployment, low interest rates and high housing affordability. The negative evidence considered in BMC’s assessment as of September 30, 2015 included: (i) unsettled circumstances associated with the general economy and housing market, as well as mortgage credit availability; (ii) Section 382 limitations related to federal net operating losses; and (iii) no taxable income in the carryback periods. Based upon BMC’s evaluation of the above positive and negative evidence, BMC concluded that it was more likely than not that its net deferred tax assets of $61.8 million as of September 30, 2015 would be realized.

BMC performed a similar analysis to assess if sufficient future taxable income would be generated to recognize the existing deferred tax assets as of December 31, 2014. BMC considered all available evidence, both positive and negative, and based on the weight of that evidence BMC determined that no valuation allowance for the deferred tax assets was needed as of December 31, 2014.

BMC accounts for excess tax benefits related to share-based compensation using the “with-and-without” method. As a result, these excess tax benefits are recognized after using limited operating loss carryforwards. Excess tax benefits that result in a reduction to income taxes payable under this method are recognized as a component of shareholders’ equity. These excess tax benefits recognized were $0.4 million for the nine months ended September 30, 2015 and $0.8 million for the nine months ended September 30, 2014.

Unrecognized tax benefits

BMC’s estimate of the potential outcome of any uncertain tax issue is subject to BMC’s assessment of relevant risks, facts and circumstances at the time. A more-likely-than-not threshold is required for measurement and recognition of tax positions taken or expected to be taken in a tax return. BMC recognizes a liability for the difference between the benefit recognized and the tax position taken or expected to be taken on the tax return. Revisions of estimated tax liabilities are recognized in the period such revisions are known and can be reasonably estimated. There were no unrecognized tax benefits as of September 30, 2015 and December 31, 2014. BMC also recognizes potential interest and penalties related to unrecognized tax benefits in income tax expense. No interest income was recognized for the nine months ended September 30, 2015 and September 30, 2014, respectively.

BMC’s income tax compliance is periodically examined by various taxing authorities. BMC’s tax returns for 2011 to 2014 are open for future examination. BMC believes that the ultimate results of examinations, if any, will not have an adverse effect on BMC’s financial condition, results of operations or cash flows.

8. Fair Values of Assets and Liabilities

BMC has no assets or liabilities measured at fair value on a recurring basis; however, from time to time BMC may be required to measure certain other assets at fair value on a nonrecurring basis. These adjustments to fair value usually result from application of lower-of-cost or market accounting or write-downs of individual assets.

BMC’s debt agreements provide a $215.0 million Revolver subject to borrowing base limitations maturing in March 2018 and $250.0 million Notes maturing in September 2018. As of September 30, 2015, there were $105.5 million borrowings outstanding under the Revolver and $250.0 million outstanding under the Notes.

BMC’s remaining debt consists of Notes, other long-term debt and obligations under equipment leases and is comprised of fixed interest rates.

The estimated market value of the Revolver approximates the carrying amount as the Revolver contains variable interest rates based on LIBOR or Prime and applicable margins. As such, the fair value of the Revolver was classified as a Level 2 measurement in accordance with ASC 820, Fair Value Measurements and Disclosures (ASC 820).

The estimated market value of BMC’s Notes is $13.3 million more than the carrying amount. The fair value is based on the institutional trading activity adjusted for liquidity. As such, the fair value of the Notes was classified as a Level 2 measurement

14

in accordance with ASC 820. Additionally, based on interest rates available to us, the estimated market value of BMC’s other long-term debt and obligations under equipment leases approximates the carrying amount.

9. Commitments and Contingent Liabilities

Legal proceedings

Claims in excess of insurance deductibles are insured with third-party insurance providers. BMC is involved in litigation and other legal matters arising in the normal course of business.

From time to time, various claims, legal proceedings and litigation are asserted or commenced against BMC principally arising from automobile accidents, construction defect claims, tort claims, contract claims, employment related and other disputes. In determining loss contingencies, BMC considers the likelihood of loss, as well as the ability to reasonably estimate the amount of such loss or liability. An estimated loss is recognized when it is considered probable that such liability has been incurred and when the amount of loss can be reasonably estimated. It is not certain that BMC will prevail in these matters; however, BMC does not believe that the ultimate outcome of any pending matters will have a significant adverse effect on BMC’s results of operations, financial position or cash flows.

10. Changes in Working Capital, Net

Net cash provided by (used by) operating activities for changes in working capital, net of effects of acquisitions, are as follows (thousands):

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

On December 1, 2015, Building Materials Holding Corporation ("BMC") was merged with and into Stock Building Supply Holdings, Inc. ("SBS"), with SBS surviving the merger (the "Merger"). Upon completion of the Merger, the combined company was named BMC Stock Holdings, Inc ("BMC Stock", the "Company"). For additional information about the Merger, see the Company’s definitive Joint Proxy and Consent Solicitation Statement/Prospectus, included in a registration statement on Form S-4 (Commission File No. 333-206421) filed with the Securities and Exchange Commission (the “SEC”) on November 2, 2015. The following unaudited pro forma condensed combined financial statements have been prepared to illustrate the effect of the Merger as of and for the nine months ended September 30, 2015, and for the year ended December 31, 2014. The unaudited pro forma condensed combined financial statements have been derived from the audited historical consolidated financial statements of SBS and BMC for the year ended December 31, 2014, and the unaudited historical consolidated financial statements of SBS and BMC as of and for the nine-month period ended September 30, 2015.

The Merger will be accounted for using the acquisition method of accounting, with SBS treated as the legal acquirer and BMC treated as the acquirer for accounting purposes. Additional information about the accounting treatment of the Merger between SBS and BMC is provided in the section entitled “The Merger-Accounting Treatment” of the definitive Joint Proxy and Consent Solicitation Statement/Prospectus filed with the SEC on November 2, 2015.

The unaudited pro forma condensed combined statements of operations reflect adjustments as if the Merger had occurred on January 1, 2014. The unaudited pro forma condensed combined balance sheet reflects adjustments as if the Merger had occurred on September 30, 2015. The historical consolidated financial information has been adjusted in the unaudited pro forma condensed combined financial statements to give effect to pro forma events that are (1) directly attributable to the Merger, (2) factually supportable and (3) with respect to the statements of operations, expected to have a continuing impact on BMC Stock.

The unaudited pro forma condensed combined financial statements are provided for informational purposes only, and this financial information is not necessarily indicative of the future financial position or results of operations of BMC Stock, or the financial position or the results of operations that would have been realized had the Merger been consummated during the periods or as of the dates for which pro forma information is presented. The unaudited pro forma condensed combined financial information does not reflect any cost savings from operating efficiencies or other synergies that could result from the Merger, including one-time costs that will be incurred to achieve operating efficiencies and other synergies. In the opinion of BMC Stock’s management, all adjustments necessary to fairly present such unaudited pro forma condensed combined financial statements have been made based upon the terms of the Merger. Certain pro forma adjustments described in the accompanying notes are based on estimates and various assumptions that BMC Stock believes are reasonable under the circumstances based on currently available information. The actual recorded amounts of the acquisition consideration transferred, the recognized amounts of assets acquired and liabilities assumed and related depreciation and amortization periods will be based on final appraisals, evaluation and estimations of fair value as of the acquisition date. As a result, actual asset and liability values established and related operating results, including actual depreciation and amortization expense, could differ from those reflected in the unaudited pro forma condensed combined financial statements.

The unaudited pro forma condensed combined financial statements, including the notes thereto, should be read in conjunction with the audited consolidated financial statements of SBS for the year ended December 31, 2014 included in SBS’s Annual Report on Form 10-K filed with the SEC on March 2, 2015, the unaudited condensed consolidated financial statements of SBS for the nine months ended September 30, 2015 included in SBS’s Quarterly Report on Form 10-Q filed with the SEC on November 5, 2015, the audited consolidated financial statements of BMC for the year ended December 31, 2014 included in the definitive Joint Proxy and Consent Solicitation Statement/Prospectus filed with the SEC on November 2, 2015, and the unaudited consolidated financial statements of BMC for the nine months ended September 30, 2015 included as Exhibit 99.1 to this Current Report on Form 8-K/A.

BMC Stock Holdings, Inc. and Subsidiaries

Notes to Unaudited Pro Forma Condensed Combined Financial Statements

1.    Description of Transaction

On December 1, 2015, BMC was merged with and into SBS, with SBS surviving the Merger. Upon completion of the Merger, the combined company was named BMC Stock Holdings, Inc. For additional information about the Merger, see the Company’s definitive Joint Proxy and Consent Solicitation Statement/Prospectus, included in a registration statement on Form S-4 (Commission File No. 333-206421) filed with the Securities and Exchange Commission (the “SEC”) on November 2, 2015.

2.    Basis of Presentation

The accompanying pro forma condensed combined financial statements were prepared in accordance with Article 11 of Regulation S-X and present the pro forma consolidated financial position and results of operations of the combined company based upon the historical financial statements of BMC and SBS, after giving effect to the combination and the adjustments described in these notes, and are intended to reflect the impact of the combination on BMC’s consolidated financial statements.

Certain reclassifications have been made to the historical presentation of SBS’s financial statements to conform to the presentation of BMC. These reclassifications have no impact on the historical gross profit, income (loss) from operations, income (loss) from continuing operations, total current assets, total assets, total current liabilities, total liabilities or total stockholders’ equity reported by SBS. Further review may result in additional reclassifications.

The combination will be accounted for under the acquisition method of accounting in accordance with ASC Topic 805, “Business Combinations” (“ASC 805”), with SBS treated as the legal acquirer and BMC treated as the acquirer for accounting purposes. As the accounting acquirer, BMC will account for the transaction by using BMC historical information and accounting policies and adding the assets and liabilities of SBS as of the completion date of the combination at their respective fair values. The allocation of the estimated purchase price is preliminary, pending finalization of various estimates and analyses, including a complete purchase price allocation study. Accordingly, the accompanying unaudited pro forma accounting for the business combination is preliminary and is subject to further adjustments as additional information becomes available and as additional analyses are performed. There can be no assurance that such finalization will not result in material changes from the preliminary accounting for the business combination included in the accompanying unaudited pro forma condensed combined financial statements. The unaudited pro forma condensed combined financial statements have been derived from and should be read in conjunction with:

• The accompanying notes to the unaudited pro forma condensed combined financial statements;

• The audited consolidated financial statements of SBS for the year ended December 31, 2014, included in SBS’s Annual Report on Form 10-K filed with the SEC on March 2, 2015 and the unaudited condensed consolidated financial statements of SBS for the nine months ended September 30, 2015, included in SBS’s Quarterly Report on Form 10-Q filed with the SEC on November 5, 2015; and

• The audited consolidated financial statements of BMC for the year ended December 31, 2014 included in the definitive Joint Proxy and Consent Solicitation Statement/Prospectus filed with the SEC on November 2, 2015, and the unaudited consolidated financial statements of BMC for the nine months ended September 30, 2015 included as Exhibit 99.1 to this Current Report on Form 8-K/A.

3.    Significant Accounting Policies

The accounting policies used in preparing these unaudited pro forma condensed combined financial statements are described in BMC’s and SBS’s audited consolidated financial statements as of December 31, 2014. Based on a preliminary review of each company’s respective accounting policy, the Company's management has determined that no material adjustments are necessary to conform SBS’s financial statements to the accounting policies used by BMC in the preparation of the unaudited pro forma condensed combined financial information. A full review of each company’s accounting policies is currently in process.

4.    Other Events

The unaudited pro forma combined condensed financial statements do not reflect certain events that have occurred or may occur. As such, the combined company’s financial statements may be materially different than the pro forma financial statements presented. The following items related to BMC and SBS are not reflected in the unaudited pro forma condensed combined financial statements:

On May 1, 2015, BMC completed the acquisition of VNS Corporation ("VNS"), enabling BMC to expand its product offerings into the southeastern United States. The purchase price was $49.3 million, which was funded through available cash and BMC’s revolving credit facility. The acquisition was accounted for using the acquisition method of accounting under ASC 805. As the acquisition was completed during the nine months ended September 30, 2015, the assets and liabilities of VNS are reflected in the

5

“BMC Historical” column in the unaudited pro forma condensed combined balance sheet as of September 30, 2015, and the results of operations from the acquisition date through September 30, 2015, are reflected in the “BMC Historical” column in the unaudited pro forma condensed combined statement of operations for the nine months ended September 30, 2015. The results of operations of VNS prior to the acquisition date are not reflected in the pro forma condensed combined statements of operations for the year ended December 31, 2014 and the nine months ended September 30, 2015 as VNS was not considered significant for pro forma purposes.

On September 1, 2015, BMC purchased certain assets and assumed certain liabilities of Marietta, Georgia-based Robert Bowden Inc. ("RBI") for an initial purchase price of $102.7 million in cash (subject to certain adjustments), which was funded primarily through the use of borrowings under the Revolver. RBI has three locations in the Atlanta, Georgia area, including its manufacturing facility in Marietta. RBI sells millwork and window products to homebuilders and residential contractors primarily in the Atlanta metro market. The acquisition was accounted for using the acquisition method of accounting under ASC 805. For the fiscal year ended December 31, 2014, RBI reported sales, net income and Adjusted EBITDA of $77.9 million, $6.5 million and $10.4 million, respectively, or approximately 5.9%, 6.9% and 13.5% of BMC’s results for the same period. RBI’s total assets as of December 31, 2014, were $36.0 million, or approximately 6.1% of BMC’s total assets as of that date. As the acquisition was completed during the nine months ended September 30, 2015, the assets and liabilities of RBI are reflected in the "BMC Historical" column in the unaudited pro forma condensed combined balance sheet as of September 30, 2015, and the results of operations from the acquisition date through September 30, 2015 are reflected in the "BMC Historical" column in the unaudited pro forma condensed combined statement of operations for the nine months ended September 30, 2015. The results of operations of RBI prior to the acquisition date are not reflected in the pro forma condensed combined statements of operations for the year ended December 31, 2014 and the nine months ended September 30, 2015 as RBI was not considered significant for pro forma purposes. For a reconciliation of RBI’s net income to Adjusted EBITDA for the year ended December 31, 2014, see section entitled “BMC Management’s Discussion and Analysis of Financial Condition and Results of Operations—Factors Affecting BMC’s Results of Operations—Acquisition of Robert Bowden Inc.” of the definitive Joint Proxy and Consent Solicitation Statement/Prospectus filed with the SEC on November 2, 2015.

In connection with the Merger, the Company entered into a credit agreement with Wells Fargo and Goldman Sachs Bank USA which provides the Company with a $450.0 million revolving credit facility. The new credit facility was used to refinance outstanding balances under the current revolving credit facilities of BMC and SBS, to support up to $75.0 million in letters of credit and to fund transaction costs, general corporate purposes and working capital. The Company incurred an underwriting fee of $2.35 million which was paid on the closing date of the credit agreement. The credit agreement was filed as Exhibit 10.1 to the Company's Current Report on Form 8-K filed with the SEC on December 7, 2015.

5.    Consideration Transferred

The consideration transferred in the Merger is calculated as follows (in thousands, except share and per share amounts):

Number of SBS shares outstanding (1)	26,186,111
SBS common stock price per share (2)	$	16.99
Deemed (for accounting purposes only) issuance of BMC stock to SBS shareholders	444,902
Fair value of SBS equity awards (3)	8,494
Total consideration transferred	$	453,396

(1)	Number of shares of SBS common stock outstanding as of December 1, 2015.
(2)	Closing price of SBS common stock as of December 1, 2015.
(3)	Reflects the fair value of outstanding SBS restricted stock units and stock options.

6.    Preliminary Fair Value of Net Assets Acquired

Under the acquisition method of accounting, the identifiable assets acquired and liabilities assumed of SBS are recorded at the acquisition date fair values. The pro forma adjustments are preliminary and based on estimates of the fair value and useful lives of the assets acquired and liabilities assumed as of September 30, 2015, and have been prepared to illustrate the estimated effect of the Merger.

6

The following is a preliminary fair value estimate of the net assets acquired:

Working capital	$	152,245
Property and equipment	117,449
Intangible assets	205,790
Other long-term assets	1,193
Long-term debt	(76,464		)
Other long-term liabilities	(32,556		)
Additional net deferred income tax liability related to fair value adjustments	(79,660		)
Identifiable net assets acquired	$	287,997
Goodwill	165,399
Total net assets acquired	$	453,396

Inventory was valued at its estimated net realizable value, which is defined as expected sales price less cost to sell, plus a reasonable margin for the selling effort. When the combined company sells through the acquired inventory, its cost of sales will reflect the increased valuation, which will temporarily reduce the combined company’s gross profit.

Personal property assets were valued using the cost approach and/or market approach, real property assets were valued using the income approach and/or market approach, trademarks were valued using the relief from royalty method, customer relationships were valued using the excess earnings method and non-compete agreements were valued using the lost profit method. In estimating the fair value of favorable lease agreements, market rents were estimated for each of SBS’s leased locations. If the contractual rents were considered to be below the market rent, a favorable lease agreement was valued by discounting the difference between the contractual rent and estimated market rates over the remaining lease term.

The final determination of the accounting for the business combination has not yet been completed. The final consideration, and amounts allocated to assets acquired and liabilities assumed in the Merger could differ materially from the preliminary amounts presented in these unaudited pro forma condensed combined financial statements. A decrease (increase) in the fair value of assets acquired or an increase (decrease) in the fair value of liabilities assumed in the Merger from those preliminary valuations presented in these unaudited pro forma condensed combined financial statements would result in a dollar-for-dollar corresponding increase (decrease) in the amount of goodwill that will result from the Merger. In addition, if the value of the acquired assets is higher than the preliminary indication, it may result in higher amortization and depreciation expense than is presented in these unaudited pro forma condensed combined financial statements.

7.    Unaudited Pro Forma Condensed Combined Balance Sheet Adjustments

(a) Reflects adjustments to record identifiable tangible and intangible assets of SBS at their preliminary estimated fair value. The allocation of purchase price is subject to change as the purchase price is determined, appraisals are completed and more facts become known.

Inventory: Adjustment reflects the preliminary estimated fair value adjustment of $11.7 million to total inventory acquired.

Property, plant and equipment: Adjustment reflects the preliminary fair market value related to the change in fair value of property, plant and equipment acquired. The preliminary amounts assigned to property, plant and equipment are as follows (in thousands):     

Land	$	20,669
Buildings and improvements	17,839
Leasehold improvements	8,012
Furniture, fixtures and equipment	33,614
Vehicles	28,903
Construction-in-progress	8,412
Total estimated preliminary fair value of property, plant and equipment	117,449
Less: SBS book value of property, plant and equipment	88,295
Pro forma adjustment to property, plant and equipment	$	29,154

Deferred financing costs: Adjustment reflects the elimination of deferred financing costs, as they will not have a future cash flow impact.

7

Intangible assets: Adjustment reflects the preliminary fair market value related to the change in fair value of identifiable intangible assets acquired in the Merger. The preliminary amounts assigned to the identifiable assets are as follows (in thousands):

Customer relationships	$	170,000
Trademarks	29,000
Favorable (unfavorable) leases	3,990
Non-compete agreements	2,800
Total estimated preliminary fair value of intangible assets	205,790
Less: SBS book value of intangible assets	20,780
Pro forma adjustments to intangible assets	$	185,010

Other accrued liabilities and other long-term liabilities: Adjustments reflect the elimination of certain deferred balances of SBS that will not have a future cash flow impact, including deferred rent and a deferred gain on a sale-leaseback transaction.

Goodwill: Adjustment reflects the preliminary estimated adjustment to goodwill as a result of the Merger. Goodwill represents the excess of the consideration transferred over the preliminary fair value of the assets acquired and liabilities assumed as described in Note 6. The goodwill will not be amortized, but instead will be tested for impairment at a reporting unit level at least annually and whenever events or circumstances have occurred that may indicate a possible impairment exists. In the event management determines that the value of goodwill has become impaired, the combined entity will incur an accounting charge for the amount of the impairment during the period in which the determination is made. A preliminary allocation of goodwill to reporting units has not been performed because the determination of reporting units of the combined company has not yet been made. The goodwill is attributable to the expected synergies of the combined business operations, new growth opportunities, and the acquired assembled and trained workforce of SBS. The goodwill is not expected to be deductible for tax purposes.

The preliminary pro forma adjustment to goodwill is calculated as follows (in thousands):

Consideration transferred	$	453,396
Less: Fair value of identifiable net assets to be acquired	287,997
Total estimated goodwill	165,399
Less: SBS book value of goodwill	7,186
Pro forma adjustment to goodwill	$	158,213

(b) Reflects estimated transaction related expenses to be incurred subsequent to September 30, 2015 of $15.0 million, consisting of $7.0 million and $8.0 million to be incurred by BMC and SBS, respectively. For pro forma presentation purposes, BMC's remaining expected transaction-related expenses are reflected as a $7.0 million increase in other accrued liabilities, a $1.7 million increase to current income taxes receivable and a $5.3 million reduction of retained earnings. SBS's remaining expected transaction-related expenses are reflected as a $8.0 million increase to other accrued liabilities, a $2.0 million increase to current income taxes receivable and a $6.0 million increase to goodwill.

(c) Reflects the netting of the current income taxes receivable/payable and long-term deferred income tax asset/liability positions of BMC and SBS.

8

(d)    Reflects the deferred income tax effects of the preliminary pro forma adjustments made to the unaudited pro forma condensed combined balance sheet using the federal statutory rate of 35.0%. The preliminary pro forma adjustments to deferred income tax is calculated as follows (in thousands):    

	Pro Forma Adjustment to Asset Acquired			Current Deferred Tax Liability (Asset)			Noncurrent Deferred Tax Liability (Asset)
Estimated fair value adjustment of inventory acquired	$	11,742		$	4,110		$	—
Estimated fair value adjustment of tangible assets acquired	29,154			—			10,204
Estimated fair value adjustment of identifiable intangible assets acquired	185,010			—			64,754
Elimination of deferred financing costs	(1,020		)	(357		)	—
Elimination of deferred rent and deferred gain on sale-leaseback transaction	2,709			182			767
Deferred tax liabilities related to estimated fair value adjustments				$	3,935		$	75,725

(e) Reflects the elimination of SBS’s historical stockholders’ equity.

(f) Under reverse acquisition accounting, the amount of common stock reflects the equity structure of the legal acquirer (the par value and the number of shares issued by SBS). The adjustment reflects the combined company’s expected 65.4 million total post-combination shares at $0.01 par value. The 65.4 million post-combination shares are based on approximately 26.2 million SBS common shares outstanding as of December 1, 2015, plus approximately 39.2 million new common shares issued as part of the Merger, which is calculated as 74.9 million BMC common shares outstanding as of December 1, 2015, multiplied by the exchange ratio of 0.5231.
