Speaking at Dow Jones' All Things D conference, Bartz, who was installed as chief executive earlier this year, said: "The other party has to have a boatload of money and the right technology and give us the right data and so forth. It's that simple."
She added there was still much work to be done on improving Yahoo's performance, noting that she took up the chief executive role in January because "Yahoo needed structure, and I'm good at that".
"Two people ran the front page, two people ran sports: Hello?" she said. "We had bigger silos inside the company than outside - the homepage people didn't want to drive traffic to the finance people."
Yahoo announced in October it would cut about a tenth of the workforce. And, unveiling Yahoo's results in April, Bartz warned the company "is not immune to the ongoing economic downturn".
Globally, Yahoo posted revenue of $1.58bn in Q1 2009. Excluding the impact of currency rate fluctuations, it said revenue for the first quarter of 2009 would have declined 8% from the first quarter of 2008.
