uncertainties that could cause actual events or results to differ materially from the events or results described in the

Use of Non-GAAP Financial Measures

This presentation includes financial measures and terms not calculated in accordance with accounting principles generally

accepted in the United States (“GAAP”) in order to provide investors with an alternative method for assessing our

operating results in a manner that enables investors to more thoroughly evaluate our current performance as compared to

past performance. We believe these non-GAAP measures provide investors with a better baseline for modeling our future

earnings expectations. Our management uses these non-GAAP measures for the same purpose. We believe that our

investors should have access to the same set of tools that we use in analyzing our results. These non-GAAP measures

should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute

for or superior to GAAP results. Our calculations of non-GAAP measures are not necessarily comparable to similarly

titled measures reported by other companies. Schedules that reconcile non-GAAP financial

measures to their GAAP equivalents are included later in this presentation.

The residential new construction market has experienced a substantial downturn in recent

years as a result of the recession

The downturn resulted in the largest decline in housing starts since the Great Depression

falling by 74% from the 2005 peak to the current trough

Building products sales have had a corresponding decline

Trends that will drive a recovery in U.S. housing demand include:

Low interest rates, the aging of housing stock, and population growth due to

immigration and birthrates exceeding death rates

The National Association of Home Builders (“NAHB”) is predicting that 2012 U.S.

single family housing starts will grow approximately 21% from 2011, with

approximately 528,000 single family housing starts predicted

NAHB predicts single family housing starts will increase to 665,000 in 2013,

representing a 26% increase over the 2012 forecast

The Macro Environment

BFS is well positioned to take advantage of anticipated renewed demand

12

Commodity Price Trends

Commodity prices have steadily increased from the beginning of the year. Higher commodity prices

will typically result in increased gross profit dollars and improved EBITDA flow through.

Financial Overview

20

Sales for 2011 were 11.2% higher than 2010 primarily due to increased sales volume

Comparing our sales growth to an 8.6% decline in U.S. single family housing starts indicates

significant market share gains

For the year, gross margins increased 150 bps, from 18.8% in 2010 to 20.3% in 2011

Margins improved 90 bps due to increased sales volume and our ability to leverage fixed costs

in cost of goods sold

Improving customer pricing, coupled with less volatility in the commodity market also

contributed to margin improvement

Margins are positioned to expand further due to operating leverage upon increased builder

demand as well as an improved commodity inventory position

Selling, general, and administrative expenses have been monitored closely by management and as a

percentage of sales decreased from 27.3% in 2010 to 24.2% in 2011 (excluding stock compensation

expense and 2010 litigation settlement)

Review of 2011 Operating Results

21

After declines in 2007-2009, revenues stabilized in 2010 and grew 11% in 2011

Historical margins demonstrate the potential for expansion from current margins as the business

builds toward historical scale and leverages a leaner cost structure

Proven ability to conserve capital through tight working capital management and reduced capital

spending

Market Share Gains

BFS sales per South Region single-family housing start for FY 2011 grew 20%

year-over-year.

Gains continued in 2012 as Q3 YTD sales per single-family start grew 9%

compared to Q3 YTD 2011.

24

Sales & Adjusted EBITDA Trends

Consistent sales and adjusted EBITDA growth

Five straight quarters of y/o/y sales growth greater than 20%

Seven straight quarters of y/o/y adjusted EBITDA improvement

In Q2 2012, achieved positive adjusted EBITDA for the first time in 19 quarters

and breakeven LTM adjusted EBITDA at the end of Q3 2012

25

September YTD 2012 Update

Sales for Q3 YTD 2012 were $783.1 million, a 33.5% increase over sales of $586.4 million for Q3

YTD 2011

Sales growth was primarily driven by volume

U.S. single family housing starts (South region) were up only 22.7% over the same period

U.S. single family units under construction (South region) were up only 3.7% over the same

period

Combination of these data points, indicate market share gains

Gross margins was 20.0% for Q3 YTD 2012 compared to 20.2% for Q3 YTD 2011. Increased sales

volume was offset by intra-quarter commodity lumber price inflation relative to quarterly customer

pricing commitments, particularly in Q2 and Q3 2012. Higher than expected sales volume resulted

in us replacing inventory during the latter half of the quarters at higher costs.

At September 30, 2012, our LTM Adjusted EBITDA had improved $23.9 million – ($0.3) million

compared to ($24.2) million for the same period in 2011
