whether as a result of new information, future events or otherwise. Any forward-looking statements involve risks and

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

forward-looking statements, including risks or uncertainties related to the Company’s revenues and operating results

being highly dependent on, among other things, the homebuilding industry, lumber prices and the economy. Builders

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.

Industry Update

10

Recent downturn in residential new construction market is without precedent since World War II

Since 2008, housing starts have been well below the long term trend of 1.5 million total starts and

1.1 million single family starts.

Overbuild/Underbuild

New Construction Market Trends

11

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 73% 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 2013 U.S.

single family housing starts will grow approximately 24% from 2012, with

approximately 664,000 single family housing starts predicted

NAHB predicts single family housing starts will increase to 855,000 in 2014,

representing a 29% increase over the 2013 forecast

The Macro Environment

BFS is well positioned to take advantage of anticipated renewed demand

12

Commodity Price Trends

Commodity prices have steadily increased since the beginning of the 2012. Higher commodity prices

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

Fully Integrated Distribution Platform

located

Size of facilities tailored to each market to meet customer needs

Offering large-scale, full-service branches in larger markets and smaller, more tailored

facilities in secondary markets

Highly customized, proprietary information technology system drives internal efficiencies

allowing the Company to respond rapidly to customers and reduce their costs

BFS operates and owns the source code to its enterprise resource planning (“ERP”)

computer system that is tailored to the building supply industry in addition to laser

technology that facilitates precision, speed and efficiency in the manufacturing process

16

Due to the breadth of its product offering (65,000 SKUs), BFS functions as a “one-stop shop”

Homebuilders value the convenience and efficiency of using one supplier throughout building process

BFS provides customers with a full range of services including professional installation, turn-key

framing and shell construction and design

Financial Overview

Review of 2012 Operating Results

Sales for 2012 were 37.4% higher than 2011 primarily driven by volume, and to a lesser extent,

commodity price inflation

U.S. single family housing starts (South region) were up only 23.1% over the same period

U.S. single family units under construction (South region) were up only 7.7% over the same

period

Combination of these data points, indicate market share gains

Gross margin decreased slightly from 20.3% in 2011 to 20.0% in 2012. Increased sales volume was

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

commitments. Higher than expected sales volume resulted in us replacing inventory during the latter

half of the quarters at higher costs.

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

percentage of sales decreased from 24.2% in 2011 to 20.4% in 2012 (excluding stock compensation

expense)

FY 2012 Adjusted EBITDA improved $21.4 million – $6.4 million compared to ($15.0) million in

2011

21

After declines in 2007-2009, revenues stabilized in 2010 then grew 11% in 2011 and 37% in 2012

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

March YTD 2013 Update

Sales for Q1 2013 were $319.7 million, a 45.7% increase over sales of $219.4 million for Q1 2012

Sales growth estimated to be driven by volume (29.7%) and price (16.0%)

U.S. single family housing starts (South region) were up only 27.4% over the same period

U.S. single family units under construction (South region) were up only 23.2% over the same

period

Gross margin was 19.5% for Q1 2013 compared to 20.6% for Q1 2012. Increased sales volume was

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

commitments.

At March 31, 2013, our LTM Adjusted EBITDA had improved $21.3 million – $13.9 million

compared to ($7.4) million for the same period in 2012
