BOSTON ( TheStreet) -- Eaton ( ETN) announced a 16% increase to its dividend as the company reported better-than-expected quarterly results, news that helped the stock rally more than 5% during Wednesday's session.

Eaton said it has upped its quarterly dividend to 58 cents per share from 50 cents, boosting the stock's dividend yield to 3.18% from 2.74% on an annualized basis. The new dividend is payable on Aug. 27 to shareholders of record on Aug. 9, the company said.

The dividend increase announcement came as Eaton posted a second-quarter adjusted profit of $1.36 a share, handily beating the Thomson Reuters average estimate of $1.17 a share. The company also offered better-than-expected earnings guidance for the third quarter and full year.

Shares of Eaton were climbing by $3.78, or 5.5% to $72.84.

Elsewhere, Airgas ( ARG) said it has boosted its quarterly dividend by 14% to 25 cents per share from 22 cents. The dividend will be payable on Sept. 30 to shareholders of record as of Sept. 15, the company said.

In addition, Airgas guided full-year earnings above the Thomson Reuters consensus target. In addition, the company once again rebuffed the hostile takeover bid from Air Products ( APD).
