Marissa Mayer to be on Yahoo earnings call Oct. 22

From the moment Marissa Mayer was hired as Yahoo CEO and announced she was pregnant, she said her leave would be short and she would likely work through it.

Mayer gave birth to a son on Sept. 30, about a week before her official due date. And while the company said the leave would be short, there was no official date set for her return.

On Thursday, Kara Swisher of All Things D reported that there was an all-hands meeting scheduled yesterday, a memo seemed to indicate Mayer would be there live and in person:

“In an internal memo from Mayer — which was signed “See you Thursday” — she has called for two “Goals All Hands” meetings this morning and this afternoon.”

No further confirmation yet about whether Mayer actually appeared, or whether she has returned full-time.

However,  a Yahoo spokesperson did confirm for me that Mayer will participate in the company’s Oct. 22 earnings call.  That will be welcome news for analysts, who are itching to hear more about Yahoo’s big vision for turning around Yahoo.

Just before the birth, Mayer presented a very broad picture of the strategies and changes she has in mind for Yahoo. But analysts were hoping to hear more. In a note to clients this week, Wedge Partners analyst Martin Pykkonnen wrote that he was highlighting the Oct. 22 in his coverage this month:

“This has much less to do with 3Q12 results than comments to be made by YHOO on their conference call (Oct 22nd) by CEO Marissa Mayer and her plans to rejuvenate the company. We’ve seen several previous YHOO CEOs fall flat with regrowth plans at YHOO, but we think Ms. Mayer brings a new and refreshed enthusiasm – especially for attracting top engineering talent to YHOO. Now, we need to hear the details, including in areas like mobile search technology, dramatic home page redesign, ad technology platforms and generating higher advertising CPMs.”
