LEGGETT & PLATT ANNOUNCES FOURTH QUARTER AND 2011 RESULTS

Carthage, MO, February 6, 2012 —

Diversified manufacturer Leggett & Platt reported fourth quarter earnings per diluted share (EPS) of $.06. Fourth quarter EPS would have been $.22, except for a restructuring-related, predominantly non-cash charge (announced on December 28) of $37 million, or $.16 per share. In the fourth quarter of 2010, EPS was $.21.

Fourth quarter 2011 sales were $854 million. Same location sales grew 6%, primarily due to inflation and higher trade sales at the steel mill.

Full Year Financial Results

Full year 2011 EPS was $1.04. Full year EPS would have been $1.20, except for the $.16 restructuring-related charge. Full year 2010 EPS was $1.15. EPS in 2011 benefitted from stock repurchases and a lower effective tax rate. Full year sales increased 8% to $3.64 billion, mainly from inflation and currency rate changes. Unit volume grew 3% primarily due to a shift in the mix of sales at the company’s steel mill (from intra-segment to trade).

The company generated $329 million of cash from operations during 2011. Major uses of cash included $231 million to fund dividends and capital requirements, and $205 million (net) to purchase Leggett stock. Net debt to net capital was 29% at year end, below the conservative end of the company’s 30%-40% target range.

CEO Comments

President and CEO David S. Haffner commented, “We remain well poised for earnings growth when the economy expands. That has not yet occurred broadly; to the contrary, in our markets, aggregate demand was essentially flat in 2011. As a result, we continue to tightly manage costs, exit unprofitable businesses, and focus on other elements of our strategic imperatives.

“Though sales grew in 2011, most of the increase was due to inflation and currency rates, which didn’t generate much profit. After improving for the last three years, EBIT margin declined in 2011 due to restructuring costs, inflation, and weak market demand for some of our products. We are dedicated to reversing this trend in 2012.

“Despite these challenges, for the fourth consecutive year Leggett & Platt stock generated a higher return for investors than did the S&P 500 index. Our shareholders continue to benefit from the company’s 5% dividend yield, 40 years of annual dividend increases, strong cash flow, stock buybacks, conservative balance sheet, and TSR-driven² strategy. As we have for over 20 years, we generated more than enough cash from operations to fund dividends and capital expenditures. Our Total Shareholder Return (TSR) for the 3-year period ending December 31, 2011, ranked in the top 38% of the S&P 500 companies, just shy of our goal to be in the top third.

“In December, we announced our first significant acquisition since 2007. Western Pneumatic Tube specializes in fabricating thin-walled, large diameter, welded tubing from titanium, nickel-based alloys, and other high strength metals for leading aerospace suppliers and manufacturers. As the leading provider of the types of extremely high-quality, critical function, non-commodity products it manufactures, Western is a competitively advantaged business that provides us diversification into a growing, profitable, attractive industry.”

Dividend and Stock Repurchases

2011 marked the 40^th consecutive annual dividend increase for Leggett & Platt, with a compound annual growth rate of nearly 14% during that period. Only two other S&P 500 members can claim as high a rate of dividend growth for as many years. At Friday’s closing share price of $23.22, the indicated annual dividend of $1.12 per share generates a dividend yield of 4.8%.

For the full year, the company purchased 10.1 million shares of its stock, and issued 3.3 million shares through employee benefit and stock purchase plans. As a result, the number of shares outstanding declined by 5% during 2011, to 139 million at year end.

2012 Outlook

Leggett anticipates 2012 sales of $3.6-3.8 billion, reflecting its belief that the economy will improve modestly. The company expects that its recent restructuring activities will benefit 2012 earnings by $.07-.10 per share, but this will be partially offset by higher anticipated interest expense and effective tax rates. Given all these factors, Leggett projects 2012 EPS of $1.20-1.40.

Cash from operations should again exceed $300 million for the full year. Capital expenditures are expected to be about $100 million, and dividend payments should approximate $160 million.

The company continues to seek acquisition opportunities that fit its strategy and meet its criteria. On January 12, 2012, the company completed its $188 million acquisition of Western Tube. Given this use of cash, stock repurchases during 2012 are anticipated to be lower than in recent years, perhaps even zero. As is typical, the company expects to issue approximately 3 million shares to employees via employee benefit plans.

SEGMENT RESULTS – Fourth Quarter 2011 (versus 4Q 2010)

Residential Furnishings – Total sales increased $25 million, or 6%, largely from inflation; unit volume grew 1%. EBIT (earnings before interest and income taxes) decreased $7 million due to restructuring-related costs of $7 million.

Commercial Fixturing & Components – Total sales decreased $4 million, or 4%. Lower sales and production levels contributed to the $3 million decrease in EBIT. Restructuring-related costs were $3 million in both periods.

Industrial Materials – Total sales increased $30 million, or 18%, reflecting steel-related price inflation and higher trade sales from our steel mill. The $21 million EBIT decline reflects $22 million of restructuring-related costs.

Specialized Products – Total sales increased $10 million, or 6%, primarily from unit volume growth in all three sectors of the segment. EBIT decreased $3 million, with the benefit from higher volumes more than offset by restructuring-related costs of $5 million.

SEGMENT RESULTS – Full Year 2011 (versus 2010)

Residential Furnishings – Total sales from Continuing Operations increased $90 million, or 5%, largely from inflation and currency, which generated little profit. Unit volume was flat. EBIT from Continuing Operations decreased $22 million, primarily due to restructuring-related costs, less favorable sales mix, inflation, and other operating costs.

2 of 5

Commercial Fixturing & Components – Total sales from Continuing Operations decreased $27 million, or 5%, due to reduced volumes in the store fixture operations. EBIT from Continuing Operations decreased $7 million as a result of the sales decline.

Industrial Materials – Total sales from Continuing Operations increased $132 million, or 18%, reflecting steel-related price inflation and higher trade sales from our steel mill. EBIT decreased $27 million mainly as a result of restructuring-related costs, and lower wire and tubing volumes.

Specialized Products – Total sales from Continuing Operations increased $107 million, or 17%, primarily from unit volume growth in all three sectors of the segment. EBIT from Continuing Operations increased $11 million, with the benefit from higher volumes partially offset by higher raw material costs, currency impacts, and restructuring-related costs.
