good work The simple model is in the attached link. Since the original post, a DCF model is the main focus and yields a slightly higher result in the $44 range. I'd consider the DCF a bit more reliable, as it takes into account specifics of dilution effect, term loan facility payoff, etc. Upon averaging the two model results, a $39 valuation is appropriate. Enjoy and adapt as you please to factor in your own assumptions.
With 5% assumed revenue growth for the next few years, we instead get a $32.60 average valuation.
Edit: Both models updated to reflect lack of termination fee and required dilution now that PG found a new buyer
