Deep-value bull case for Ampco-Pittsburgh (AP), arguing its Aerofin subsidiary's nuclear heat-exchanger monopoly and SMR/navy exposure make its ~$105M market cap and 0.2x P/S deeply undervalued versus peer Graham Corp.
Unpriced research observations (excluded from Calls and Returns):
AP — LONG The author argues Ampco-Pittsburgh is a deep-value play because its Aerofin subsidiary invented the heat exchanger and holds over 93% market share in cooling coils for the entire US nuclear fleet. At ~$105M market cap and 0.2x P/S, AP generates double the revenue of peer Graham Corp ($GHM, 3.4x sales) yet trades at 1/7th the market cap, which the author calls a massive mispricing. Catalysts cited include real nuclear and defense revenue via a partnership with BWX Technologies supplying thermal management for the US Navy and next-gen SMR prototypes, plus an ASME N-Stamp regulatory moat. The author states he holds over 50,000 shares and won't sell until $50. resolved_asset_type_mismatch
Compared to its peer Graham Corp ($GHM), which trades at 3.4x Sales, $AP generates double the revenue but trades at 1/7th the market cap. This is a massive mispricing that won't last.
