What does Vishay Intertechnology do?

Vishay makes the small basic parts found inside almost every electronic device, such as transistors, diodes, resistors, capacitors and inductors. These parts switch power, protect circuits, control voltage and current, store energy and sense light. Its customers make cars, factory equipment, computers, consumer gadgets, telecom gear, and military, aerospace and medical systems.

What is Vishay Intertechnology's fair value?

On an owner-earnings DCF, Vishay Intertechnology's most-likely fair value is about $11, versus a recent price near $34. A margin-of-safety estimate, not a price target. Analysis, not advice.

How Vishay Intertechnology makes money

Vishay manufactures and sells high volumes of discrete semiconductors and passive components through six product segments. Its customers are makers of electronic equipment in the automotive, industrial, computing, consumer, telecom, defense and healthcare markets, across the US, Europe, Israel and Asia.

What Vishay Intertechnology does

Vishay Intertechnology, founded in 1962 and headquartered in Malvern, Pennsylvania, makes both discrete semiconductors and passive electronic components. It reports six segments. The semiconductor side has three: MOSFETs (low-, medium- and high-voltage power transistors and power ICs), Diodes (rectifiers, protection diodes, thyristors and power modules) and Optoelectronic Components (IR emitters and detectors, optocouplers, solid-state relays, optical sensors and LEDs). The passive side also has three: Resistors, Inductors and Capacitors. It sells under a large group of long-established brands, including Siliconix, Dale, Draloric, Beyschlag, Sfernice, IHLP, Sprague, Vitramon, Roederstein and BCcomponents. It operates in the US, Germany, the rest of Europe, Israel and Asia, and its customers are in the automotive, industrial, computing, consumer, telecom, military, aerospace and healthcare markets. Because it makes such a wide range of basic components, its business follows overall demand for electronics.

What is Vishay Intertechnology worth?

On an owner-earnings DCF, Vishay Intertechnology's most-likely value is about $11 versus a recent price near $34 (69% above fair value). But TacticScale only calls a stock undervalued when the price sits below its conservative no-growth floor (~$6) with a margin of safety — so the honest verdict here is “Stretched — richly priced.” Fair value earns its keep only at the extremes, not in the wide middle.

Verdict: Stretched — richly priced

Owner-earnings fair value · recent price ≈ $34

Fair value (most likely)

$11

Range

$9–$15

No-growth floor

Price

~$34

Today's $34 is above even the optimistic Bull case ($15) — the market expects faster, longer growth than modeled here. Expensive unless that extra growth actually shows up.
