A lagged javascript function prevents webread from getting all data from a webpage. Resolve?

So I am trying to get earnings dates from Yahoo. Their API does not have references for this, however their webpage runs a javascript function to get earnings dates from another unknown url. Webread reads the initial state of the page, however the javascript function then runs, and the html changes 2 seconds later, at which point I would like to grab the text of the url. Here is the website:

https://finance.yahoo.com/quote/adbe?ltr=1 Earnings Date goes from N/A to the relevant date after 2 seconds when loading

Does anyone have a solution to grabbing the date instead of the initial condition of N/A from this website? Help much appreciated, will
