We apply the following assumptions:  2025E: midpoint of A) Tempest Management Plan and B) peer comparables (based on the average excluding the low and high peers)  2026E: peer comparables (using the same methodology as above), flatlined thereafter through the end of the projection period  The resulting projections are shown below, which imply a 10% Revenue CAGR from 2024E to 2028E and 2028E Adjusted EBITDA Margin of 18%, resulting in 2028E Adjusted EBITDA of $274m (vs. Tempest Management Plan Adjusted EBITDA of $380m)  Based on this sensitivity case, the DCF analysis implies a valuation per Tempest share of $4.03 to $6.10 1 Rev e n u e Ass u m p t io n s Adjus t e d E B ITDA Ass u m p t io n s CY2028E CY2027E CY2026E CY2025E CY2024E $2,004 $1,676 $1,396 $1,152 $1,037 T e mpe s t MP 2 R e v e n ue 20% 20% 21% 11% (8%) % Y o Y Gr o w t h 1,497 1,365 1,245 1,136 1,037 S e n s itivity C a s e R e v e n ue 10% 10% 10% 10% (8%) % Y o Y Gr o w t h 10% 8% P eer Av e rag e % Y o Y Gr o w t h 3 M em o : % Y o Y Gr o w t h 14% 8% EPAM 21% 17% Globant – 4 11% Endava – 4 7% Accenture 5% 6% Capgemini 5% 4% Cognizant CY2028E CY2027E CY2026E CY2025E CY2024E $380 $307 $235 $155 $86 T e mpe s t MP 2 Ad j.
