Hola Jairo,

Sí, es posible que se trate de un error y que se refiera a 2010. Sin embargo, según el apartado sobre EEUU en la página sobre años fiscales de Wikipedia, parecería ser que las empresas tienen un margen para elegir su propio año fiscal:

United States
The U.S. government's fiscal year begins on October 1 of the previous calendar year and ends on September 30 of the year with which it is numbered. Prior to 1976, the fiscal year began on July 1 and ended on June 30. The Congressional Budget and Impoundment Control Act of 1974 stipulated the change to allow Congress more time to arrive at a budget each year, and provided for what is known as the "transitional quarter" from July 1, 1976 to September 30, 1976. As stated above, the tax year for a business is governed by the fiscal year it chooses.

For example, the United States government fiscal year for 2011 ("FY 2011" or "FY11") is as follows:

1st Quarter: October 1, 2010 - December 31, 2010
2nd Quarter: January 1, 2011 - March 31, 2011
3rd Quarter: April 1, 2011 - June 30, 2011
4th Quarter: July 1, 2011 - September 30, 2011

Si persiste la duda, pediría confirmación al cliente del año fiscal que utiliza la empresa.

Otra solución sería tratar de consultar informes/notas de prensa anteriores. Por ejemplo, intenta ver si encuentras resultasod para el año fiscal 2009 o 2010 y mira a ver cuándo está fechada la noticia.

Suerte,

Álvaro :O)

Otras explicaciones en la misma página:

A fiscal year (or financial year, or sometimes budget year) is a period used for calculating annual ("yearly") financial statements in businesses and other organizations. In many jurisdictions, regulatory laws regarding accounting and taxation require such reports once per twelve months, but do not require that the period reported on constitutes a calendar year (i.e., January through December). Fiscal years vary between businesses and countries. Fiscal year may also refer to the year used for income tax reporting.

In addition, many companies find that it is convenient for purposes of comparison and for accurate stock taking to always end their fiscal year on the same day of the week, where local legislation permits. Thus some fiscal years will have 54 weeks and others 53. Major corporations that adopt this approach include Cisco Systems[1] and Tesco.

Nevertheless, the fiscal year is identical to the calendar year for about 65% of publicly traded companies in the United States and for a majority of large corporations in the UK and elsewhere (with notable exceptions Australia, New Zealand and Japan).

¿Te refieres a la misma cifra de ventas? Parece demasiada casualidad como para no tratar de confirmarla. :O)
