1. Business Overview (Item 1)

Core Technology & Applications

• Spintronics fundamentals: giant magnetoresistance (GMR) and tunneling magnetoresistance (TMR) structures with film thicknesses of just a few nanometers (atomic layers).
• Products:
• Magnetic sensors (position, rotation, speed detection): catalog devices for Industrial Internet of Things (IIoT), and custom sensors for medical implants and other specialized applications.
• Couplers (isolators): GMR-based digital isolators for factory automation and power electronics—higher data speeds, channel density, and reliability vs. optical or transformer couplers.
• Power products: isolated DC-DC converters and voltage regulators that combine data isolation (couplers) and power transfer for battery storage systems, EVs, and industrial IIoT networks.
• MRAM: specialized magnetoresistive memory for anti-tamper, military, and industrial use; lower bit-density roadmap.

Manufacturing & Quality

• End-to-end manufacturing in Eden Prairie, MN: front-end wafer fabrication in ISO 9001:2015–certified cleanrooms, back-end U.S. test and inspection.
• Strategic use of foundry wafers (integrated circuitry) and in-house deposition/patterning of GMR/TMR layers.
• ISO 9001 and ECS/CIG place-of-manufacture approvals; ISO 9001:2015 quality management. Medical sensors built under strict medical device standards.

Customers & Distribution

• Global distributors covering 75+ countries: Digi-Key, America II, Angst+Pfister, plus private-brand IDMs.
• Major customers: Abbott Laboratories (medical) and others, accounting for  > 50% of total revenue (35% and 19%), with multi-year supplier agreements in place.

Competition & Moat

• Sensor rivals: Hall-effect and AMR devices; electromechanical reed switches in medical.
• Coupler alternatives: optical, inductive, capacitive, RF isolators.
• Key advantages: smaller form factor, higher sensitivity and speed, lower power, reliability (no moving parts), long product life.
• Intellectual property: 50+ issued U.S. patents, global patents, plus government-funded inventions. No key patents expire in the next 12 months.

Risks (Item 1A)

• Single-source wafer and materials risk; Asian packaging dependencies.
• Customer concentration and loss of major accounts (Abbott, distributors).
• Product liability in medical devices; potential recalls and reputational damage.
• Cyclicality of semiconductor/industrial end markets.
• Geopolitical trade barriers, tariffs on imports/exports.

Net income	$15.1 M	$17.1 M	–12.0%
EPS (diluted)	$3.11	$3.54	–12.1%

• Margin expansion: stronger mix of direct sales and higher-margin products offset volume declines.
• Expense growth: stepped-up R&D for next-generation TMR sensors, MRAM; SG&A rose to support sales and marketing expansion.

Cash Flow & Liquidity

• Operating cash flow: +$14.3 M (FY 2025) vs. +$18.2 M (FY 2024). A robust cash generator.
• Investing: $1.26 M in capex (add’l $1.13 M down-payment for new production equipment due FY 2026); $11.3 M net in marketable securities purchases offset by $15.2 M maturities.
• Financing: $19.3 M in dividends; $0.11 M from option exercises.

Balance Sheet ($M)	Mar 31 ’25	Mar 31 ’24	Comments
Cash & eq.	8.0	10.3	Decrease due to dividends, inventory build.
Marketable sec.	47.9	52.5	High-grade munis and corporates; unrealized gain of $0.71 M.
Receivables	3.6	3.1	40d DSO; concentration on two large customers.
Inventory	7.4	7.2	Raw, WIP, FG to buffer against supply chain risk.
Total assets	64.3	66.8
Liabilities	2.0	1.2	No debt; lease liability $0.92 M.
Equity	62.3	65.6	Retains > 95% of capital.
