Wireless Ronin Technologies, a Minnetonka maker of software for digital advertising signs, is merging with Broadcast International of Salt Lake City in a stock transaction of undisclosed value.

Wireless Ronin's software manages the flow of advertising messages to digital signs, and in the past its clients have included Kentucky Fried Chicken, Reuters and Chrysler.

Wireless Ronin had a loss of $3.6 million in 2013 on sales of $6.8 million. Its market capitalization Thursday was $4.75 million, based on a closing stock price of 95 cents a share on the over-the-counter market, up 15 cents, or nearly 19 percent.

The company was removed from the Nasdaq market last May for lack of sufficient shareholder equity.
