Digimarc Corporation (DMRC), the online marketing company, witnessed an after-hours plunge of 13.09% in its stock price on Wednesday, following the release of its disappointing fourth-quarter earnings and annual results.

In the intraday trading session, the company reported a net loss of $8.6 million, or $0.40 per share, for the fourth quarter. Adjusted losses were $0.22 per share, missing analysts' expectations. The company's revenue for the quarter stood at $8.7 million.

For the full year, Digimarc reported a substantial net loss of $39 million, or $1.83 per share, on revenue of $38.4 million. The company's lackluster performance and widening losses appear to have triggered the after-hours sell-off in its stock.
