Preliminary Draft Subject to Review and Significant Revision 15/11/2021 ▪ “We believe CSPR's lower multiple is due to the co. remaining unprofitable (while all others generate profits). Plus, CSPR's performance has been less consistent than the others in the sector over the past year. As such, the purchase price of 0.4x '22E revs appears fair, in our view.” 03/11/2022 ▪ “We think that TIG’s financial profile has come less differentiated in the current hard market, with most commercial peers enjoying comparable or better growth and margins. Also, we believe that TIG is exposed to the risk of downward EPS revisions” 11/01/2023 ▪ “$19/share is higher than where DCT has traded since late 2021, and ~6x FY24E EV/Sales makes sense with a turn premium to close competitor/valuation comp GWRE. The go-shop period has been a focus for several investors, and we think likelihood of a competing bid is low” 23/01/2023 ▪ “We believe SUMO is an inferior asset to others in the observability/security space and should reflect a discounted multiple (in the 3-5x range). we point to the significant difference in scale versus Splunk, its closest competitor” 08/11/2021 ▪ “MCFEs fundamentals are set to soften as comps get tougher and competitive pressures increase. NortonLifeLock's proposed merger with Avast is set to close in mid CY22. This will create a challenger that can outmuscle MCFE in competitive situations with OEM partners, removing a funnel for customer acquisition. Furthermore, McAfee might have to ramp marketing spend to match this larger competitor, limiting margin accretion” 12/10/2022 ▪ “While KnowBe4 has been executing quite well and the firm had yet to note any signs macro slowdown, we likewise know this remains a competitive space, and the reality is that bets on things like SecurityCoach and PasswordIQ have yet to be proven out – that’s to say, we can’t fault the team for selling here” 02/09/2022 ▪ “We believe F45 Training's differentiated technology-enabled platform, strong global presence, and rapidly growing studio footprint are likely to further solidify the company’s competitive positioning in the global fitness industry. Additionally, we believe there is meaningful opportunity for the company to gain market share, as it continues to grow its global studio footprint.” 14/12/2022 ▪ “This price target represents ~50x our CY23 adj. EBITDA and ~2.6x our CY23 sales estimates. Clearly, this is well above peers', entirely reflecting the take private transaction offer. That's why we're Equal Weight.” 11/10/2022 ▪ “This is also slightly above security peer average currently trading at 7.2 EV/CY23 sales and 0.34X growth adjusted. Given recent macro headwinds and negative near-term profitability, we think this is a favorable outcome for the company.” 11/10/2022 ▪ “At the acquisition price of $7.50, UserTesting shares are valued at 4.9 times our 2023 revenue estimate, in line with the SaaS peer group median of 4.8 times. In our view, a materially higher bid is unlikely given recent volatility in software markets and the hefty premium that Thoma Bravo paid. Thus, we are downgrading our rating on UserTesting to Market Perform. Primary risks include competition from larger software vendors in adjacent categories, contributor network churn as the economy normalizes, and a return to traditional lab testing as COVID-19 abates.” Recent IPO Take-Privates (4/6) 5 Source: Broker Reports
