Photronics (PLAB) Deep Dive — Own the Semiconductor Bottleneck at 5x EBITDA

INFERENCE Photronics is the only pure-play publicly-traded photomask company in the United States, operating in a structural oligopoly with Japan's Toppan (Tekscend) and DNP. The photomask market is a critical bottleneck in semiconductor manufacturing — every chip design requires photomasks before a single wafer can be processed, yet the merchant market is controlled by just three suppliers holding >75% share. PLAB trades at 4.86x EV/EBITDA versus the semiconductor average of ~38x P/E, representing one of the most extreme valuation disconnects in the semi supply chain.
