It really depends on what you think is discriminant for this data, but when I look at the HTML, it seems the FONT element with the BGCOLOR set to #ffffff is, so that's the corresponding Html Agility Pack code:

HtmlDocument doc = new HtmlDocument();
doc.Load(yourHtmlFile);
HtmlNode node = doc.DocumentNode.SelectSingleNode("//font[@color='#ffffff']");
Console.WriteLine(node.InnerText.Trim());

will output:
