LEGGETT & PLATT REPORTS RECORD QUARTERLY EPS

Carthage, MO, July 30, 2015 —

Diversified manufacturer Leggett & Platt reported record quarterly earnings of $.54 per share. EPS from continuing operations was $.53, an increase of $.05 versus 2014. Earnings benefited primarily from higher unit volumes, partially offset by a higher effective tax rate.

Sales from continuing operations were $997 million, a second quarter record and an increase versus second quarter 2014 (during which sales increased 9%). In the current quarter, sales volume grew 9% — roughly half from same location unit volume and half from acquisitions — but was partially offset by a 5% impact from raw material-related price deflation and currency translation.

EBIT margin improved 130 basis points versus second quarter last year, from 10.7% to 12.0%, as a result of higher sales, pricing discipline and improved capacity utilization.

CEO Comments

Board Chair and CEO David S. Haffner commented, “We continue to be very pleased with the progress we’re making in 2015. In the second quarter we extended our string of strong quarterly results that began in the second quarter of last year.

“Nearly all of our businesses experienced volume growth during the quarter, despite strong prior year comparisons. During the second quarter we saw unit volume growth in excess of 70% in Comfort Core innersprings and in adjustable beds. In addition, we experienced organic volume growth in excess of 10% in U.S. Spring, Fashion Bed, Automotive, Aerospace, and Machinery. These gains were partially offset by lower sales in CVP.

“We posted record sales and EPS during the second quarter, and achieved our highest quarterly EBIT margin in 15 years. For the full year, we expect similar results: record sales from continuing operations, our highest EBIT margin since 2000, and record EPS.

“We are achieving these results while maintaining our strong financial base. At quarter’s end, we had over $500 million available to us through our commercial paper program. Net debt to net capital was 36%, comfortably within our 30% - 40% target range.”

Dividends and Stock Repurchases

In May, Leggett & Platt’s Board of Directors declared a $.31 second quarter dividend, one cent higher than last year’s second quarter dividend. 2015 marks the 44^th consecutive annual dividend increase for the company, with a compound annual growth rate of 13%. Only one other S&P 500 company can claim as high a rate of dividend growth for as many years.

At yesterday’s closing share price of $49.79, the indicated annual dividend of $1.24 per share generates a dividend yield of 2.5%.

During the second quarter the company purchased 1.2 million shares of its stock at an average price of $48.04, and issued 0.2 million shares through employee benefit plans and option exercises. For the first half of the year, the company purchased 2.8 million shares, and issued 1.8 million. The number of shares outstanding decreased to 136.8 million.

TSR Results

In 2007, the company changed its chief strategic focus from primarily emphasizing revenue growth to pursuing Total Shareholder Return (TSR¹). L&P’s principal financial goal is to generate TSR that ranks among the top third of the S&P 500 companies over rolling 3-year periods.

For the three year period that will end in December of this year, the company has so far (over the last 31 months) generated annual TSR of 31% per year. This performance ranks within the top 20 percent of the S&P 500, exceeding the company’s goal.

2015 Records Anticipated

Leggett & Platt posted record adjusted EPS² from continuing operations for each of the last three years, and expects to do so again in 2015. The company also expects to achieve, in 2015, record sales and EBIT from continuing operations, and its highest EBIT margin since 2000.

Accordingly, the company is raising its EPS guidance, and now projects 2015 EPS of $2.00 - 2.15. Sales are anticipated to be $3.95 - 4.10 billion, growing 4% to 8%, and meeting or exceeding the company’s 4% - 5% annual growth target. This sales forecast includes an expected 5% reduction in sales from raw material-related price deflation and currency translation impacts.

Cash from operations should exceed $350 million in 2015. Capital expenditures are expected to be roughly $120 million, and dividend payments should approximate $170 million.

As has been the company’s practice, after funding dividends and capital expenditures, remaining cash flow will be prioritized toward competitively advantaged acquisitions, which must meet stringent strategic and financial criteria. Should no acquisitions come to fruition, and if excess cash flow is available, the company has standing authorization from the Board of Directors to repurchase up to 10 million shares each year. No specific share repurchase commitment or timetable has been established; however, the company currently anticipates the purchase of between 3 and 5 million shares during 2015, and the issuance of approximately 2.5 million shares via employee benefit plans and option exercises.

SEGMENT RESULTS – Second Quarter 2015 (versus the same period in 2014)

Historical financial amounts reflect the new segment structure described below.

Residential Furnishings – Total sales increased $48 million, or 10%. Same location sales improved 3%, with higher unit volume in most product categories (+7%) partially offset by the impact of raw material-related price deflation and currency translation (-4%). Acquisitions increased sales by 7%. EBIT (earnings before interest and income taxes) increased $2 million; the benefit from higher sales was partially offset by increased performance-based compensation expense.

Commercial Products – Total sales increased $35 million, or 28%. Same location sales grew 18%, primarily from strong demand growth in Adjustable Bed. Acquisitions increased sales by 10%. EBIT increased $3 million primarily due to higher sales.

2 of 5

Industrial Materials – Total sales decreased $18 million, or 9%, due to steel-related price decreases. Unit volumes were basically flat. EBIT increased $6 million, primarily from cost reductions and pricing discipline.

Specialized Products – Total sales increased $1 million, with volume gains in Automotive, Aerospace, and Machinery offset by currency translation impacts (-5%) and volume declines in CVP. EBIT increased $1 million, primarily from higher volume, which was largely offset by increased performance-based compensation expense.

Revised Segment Structure

As disclosed in its 8-K filed on April 16, 2015, the company reorganized its operating segment structure, given the divestiture last year of the majority of the Store Fixtures operations, and the retirement of one of the operating segment presidents. The 18 business units are now organized as follows:
