@laoshi - I was just about to hit post on my writeup for the same announcement! :P
Big fan of the acquisition - $2.6m cost (roughly 10% of market cap) and adding 20% to the bottom line (so about $800k) before tax, seems like a good deal on the face of it. Then factoring in how it's a crucial step in the continued vertical integration plan, and the 25 years of experience and patented tech they possess.
I continue to be impressed with management and their efforts to make these smart acquisitions, while still running a profitable & operationally cashflow positive business.

ProEng covers the highlighted stage 4 components, and the hydrogeological consulting is covered by the consulting division they launched six months ago. Not to mention the test pumping component was only announced about 12 months ago too.
@laoshi - Continued good news from Vysarn. Even better to see that it involves re-deploying a rig from dry hire (equipment only), to the full drilling & boring service, so the earnings per rig will be improved.
Will hopefully be a good opportunity for them to employ their new consulting division.
Very excited on the outlook for these guys.
@bjbart - I think you raise a good point on their competitive advantage, and it is one of the few concerns I have for the company. However barriers to entry are generally quite high - I recall reading that to get a brand new rig (which to my knowledge are exclusively manufactured in and shipped from the US) cost around $5m each.
The standard seems to be you need two rigs on every job, one working and one on standby in the case of breakdown. Meaning you would need a $10m investment to be able to run a single job, when you could pay margins of that for the service of having bring the rigs in.
Still a risk of some of the larger companies that are cashed up going a building a fleet of their own, but Vysarn seems to be in a great spot given the current capacity issues (where the current workflow is exceeding the amount of rigs available). I think their intention to vertically integrate the de-watering service is a good sign that they realise the current lucrative situation may not last, and they need to use these earnings to build value adding systems in the long run.
