Shares of

JLG Industries

(JLG)

were among the

NYSE's

losers Friday, falling 9.2% after the company swung to a first-quarter loss and warned that full-year earnings would fall short of expectations.

The maker of construction equipment posted a first-quarter loss of 20 cents a share on sales of $307 million. The quarter's loss included $26.8 million in unrecovered steel costs and an integration expense of $1.9 million. The company, which had expected unrecovered steel costs of $20 million during the quarter, said the price of steel has climbed even more than it had anticipated. Instead of the 75% jump in weighted average steel costs it had originally forecast for this year, prices will jump more than 100%.

Looking ahead, JLG said that it expects second-quarter results to be challenged by rising steel prices, but it said that it will pass along price increases to its customers, a move that will help mitigate the damage. For the full year, the company forecast a profit of $1 to $1.15 a share. Analysts polled by Thomson First Call are expecting 2005 earnings of $1.22 a share. Shares traded down $1.76 to $17.30.

Electronics Boutique

(ELBO)

fell 7.5% after the video-game retailer posted strong third-quarter results but warned that its fourth-quarter earnings would fall below expectations. During the third quarter the company earned 30 cents a share on sales of $446 million. Analysts were expecting earnings of 29 cents a share on sales of $446.3 million. Looking ahead, Electronics Boutique forecast a fourth-quarter profit of $1.62 to $1.72 a share on sales growth of 18% to 21%. That would imply fourth-quarter sales of $792.4 million to $812.5 million. Analysts had been expecting earnings of $1.73 a share on sales of $814.8 million. Shares traded down $3.09 to $38.26.

Shares of

UnumProvident

(UNM) - Get Report

rose 11.8% after the insurer settled claims by several states that it improperly handled disability claims. The settlement came after the conclusion of a multistate market conduct examination led by Maine, Massachusetts and Tennessee. The company said it would record an after-tax loss of $88 million, or 29 cents a share, after it obtains the consent of two-thirds of the remaining 47 states and two jurisdictions. UnumProvident said the examination didn't turn up any violations of law or market conduct regulations. Still, the company did say the report identified "areas of concern." As a result, the company has made changes and enhancements in the way it handles disability claims. Shares traded up $1.62 to $15.35.

Hughes Supply

(HUG)

rose 7% after the company posted third-quarter earnings that beat expectations and said fourth-quarter sales would be better than expected. The construction products company earned 54 cents a share on sales of $1.17 billion. Analysts were expecting earnings of 52 cents a share on sales of $1.12 billion. Looking ahead, Hughes forecast fourth-quarter earnings of 25 cents to 30 cents a share on sales of $1.04 billion to $1.07 billion. Analysts had been expecting earnings of 27 cents a share on sales of $989 million. Shares traded up $2.12 to $32.26.

Shares of

Compass Minerals

(CMP) - Get Report

fell 5.6% after the company said that several shareholder groups would sell more than 4 million shares in a secondary stock offering. The selling shareholders include Apollo Management, Mosiac Global Holdings and Compass Mineral employees. After the sale, it's anticipated that Apollo will not directly hold any shares of Compass Minerals. As a result, Compass believes that some of its board members who are affiliated with Apollo will step down. Shares traded down $1.35 to $22.61.
