Market Evaluation

FSS FY2026 market evaluation: at ~$80-130 share price + ~60-61M diluted shares = ~$5-8B market cap; ~$0.50 aggregate annual dividend + ~0.5-0.7% aggregate dividend yield. Selected primary FSS peers: Oshkosh Corporation (OSK, ~$6-8B Mcap; specialty vehicles + access equipment) + Terex (TEX, ~$3-4B; specialty vehicles + aerial work platforms) + Wabash National (WNC, ~$0.8-1.2B; specialty trailers) + Manitowoc Company (MTW, ~$0.4-0.7B; cranes + specialty vehicles) + Allison Transmission (ALSN, ~$8-10B; commercial vehicle transmissions) + Caterpillar (CAT, ~$130-150B; construction + mining + Defense equipment) + Deere & Company (DE, ~$120-140B; Agriculture + Construction equipment) + Cummins (CMI, ~$45-55B; engines + components) + Whelen Engineering (private; #2 US emergency vehicle warning) + ECCO Safety Group (private; warning lights + sirens) + Soundoff Signal (private; emergency vehicle warning) + selected various aggregate US + global specialty vehicle + safety + security signaling equipment companies. Selected FSS ~25-35x P/E (premium specialty vehicle + safety + security signaling with Inflation Reduction Act + Infrastructure Investment & Jobs Act + lead service line replacement demand tailwind + ~$0.95-1.10B aggregate backlog + ~10-year Jennifer Sherman CEO leadership) + selected ~15-22x EV/EBITDA + selected ~0.5-0.7% dividend yield + selected aggregate ~$2.20-2.45B aggregate FY2026 revenue + selected aggregate ~$4.15-4.55 aggregate FY2026 EPS + selected aggregate ~$60-145M aggregate FY2026 capital return + selected aggregate Environmental Solutions Group + Safety & Security Systems Group pipeline. FY2026 base case: ~$2.20-2.45B aggregate revenue + ~$4.15-4.55 adj. EPS + ~$60-145M aggregate capital return. Bull case: Environmental Solutions Group pipeline acceleration (Inflation Reduction Act + Infrastructure Investment & Jobs Act + lead service line replacement demand acceleration to ~$1.95-2.15B FY2026 Environmental Solutions Group revenue + ~$1.05-1.25B aggregate backlog) + Safety & Security Systems Group pipeline acceleration (Federal Signal + Hadady + Tomar emergency vehicle warning + Outdoor warning sirens + Mass notification systems expansion) + post-2021 OSW Equipment + Repair integration synergies completion drives ~$2.40-2.60B aggregate revenue + ~$4.50-4.95 EPS. Bear case: Oshkosh + Terex + Wabash + Manitowoc + Allison + Caterpillar + Deere + Cummins + Whelen + Code 3 + ECCO + Soundoff competitive intensification + Inflation Reduction Act + Infrastructure Investment & Jobs Act policy considerations + Municipal + Utility infrastructure spending cycle weakness + Industrial + Oil & Gas vacuum truck cycle considerations + Police + Fire + Emergency Medical Services budget cycle considerations + post-January 2016 Jennifer Sherman CEO succession planning considerations (~10-year tenure) drives ~$1.95-2.05B revenue + ~$3.30-3.65 EPS.
