Mobify (2016): For every 100ms decrease in homepage load speed, Mobify's customer base saw a 1.11% lift in session based conversion, amounting to an average annual revenue increase of $376,789. Similarly, for every 100ms decrease in checkout page load speed, Mobify's customers saw a 1.55% life in session based conversion, amounting to an average annual revenue increase of $526,147 [2].
Staples (2014): conversion increase per second [3].
Or the Obama campaign (2012): making the page 60% faster increased donations by 14% [4].
More new studies from recent years can be found at WPO stats [5].

Well. 100% of web page needs more than 3 seconds to load on my mobile connection.
We'll both agree that I ain't a statistically fair sample. I join @icebraining on that we need information that is relevant to the mobile web.
[2] is behind a paywall.
[3] is quoting all the common worthless old studies. There are some graphs and stuff but lacking test methodologies and information. Graphs are showing a few percent of gains, and latencies going from 1s to 10s, which is a lot less effect than other studies.
[4] is out of topic and gives no data. (x% of what? absolute latency? before? after? well, they didn't test for latency and impact on revenue)
