Is Allegro MicroSystems profitable in 2026?

Yes. Allegro reported FY26 (ended March 27, 2026) net sales of $890M, up 23% YoY, non-GAAP EPS of $0.54 (more than doubled YoY), and a record full-year free cash flow of $125M, per its May 7, 2026 earnings release.

Did onsemi acquire Allegro MicroSystems?

No. Onsemi made an unsolicited $6.9B all-cash bid at $35.10/share on March 5, 2025. Allegro's board rejected it as inadequate on March 7, 2025, and onsemi withdrew shortly after. The takeover threat remains unresolved as of mid-2026.

Who owns Allegro MicroSystems?

Sanken Electric of Japan remains the largest shareholder, holding about 32.5% after Allegro repurchased 39M shares from it in August 2024 for $665.9M plus a $400M term loan. JPMorgan Chase held ~6.80% (12.7M shares) as of June 2026.

Could AI replace Allegro MicroSystems' products?

No. Allegro makes physical Hall-effect and TMR magnetic sensor ICs and power semiconductors for automotive and data-center hardware; AI software cannot substitute for physical current-sensing or power-conversion chips, and AI data-center buildout is instead a growing demand driver for Allegro's sensors.

Is Allegro MicroSystems a safe company to join in 2026?

Headcount reached 4,250 employees as of March 27, 2026, up 4.68% year-over-year, alongside a 23% revenue rebound to $890M in FY26 after a 31% FY25 downturn, suggesting recovering, growth-stage hiring rather than contraction.

Who is Allegro MicroSystems' biggest competitor?

Infineon Technologies and Melexis are cited as Allegro's principal rivals in automotive magnetic field and current sensing, while onsemi is a direct competitor that made an unsolicited $6.9B acquisition bid in March 2025, later withdrawn.

The call

Allegro's chips sit inside AI's physical build-out rather than under threat from it, while onsemi's unresolved takeover interest remains the bigger open question.

Allegro MicroSystems designs tiny sensors and power chips for automobiles and AI data centers. Copying what Allegro does is very hard because carmakers lock in its sensors during the design phase, and the company holds special safety certifications (ASIL-D) that take years for rivals like onsemi, Infineon, or Melexis to earn on their own. The company is making more cash than it spends, and no AI software can replace physical sensors made of metal and silicon. The biggest wildcard is whether onsemi or another large chip maker will try to buy Allegro again after their $6.9 billion offer was rejected in March 2025, and whether car sales stay strong or crash again like they did in 2025.

Why

AI pressure: None apparent. AI does not replace Hall-effect or TMR sensors; AI data-center buildout is a growing customer, now 14% of sales. Could AI do the core job? Unlikely.

Bigger players: onsemi. onsemi's $6.9B unsolicited bid was rejected and withdrawn in 2025, but the takeover threat has not gone away. Could a giant copy it? Probably.

What protects it. ASIL-D safety certification and years-long automotive design-in cycles make switching suppliers costly and slow.

What would change this call

Onsemi or another consolidator makes a renewed acquisition approach for Allegro. Would show rivals view Allegro's independence and moat as weakening.
Infineon, Melexis, or TI announces a current-sensing or safety-PMIC platform winning named automotive design slots from Allegro. Would show Allegro's TMR/current-sensing technical lead is being overtaken.
Allegro's China revenue share drops sharply in quarterly filings versus the ~28% level. Would show domestic Chinese competitors are displacing Allegro on price.

Key numbers

FY26 net sales $890M, up 23% YoY (2026-03-27)
Record full-year free cash flow of $125M (2026-03-27)
Data center/AI sales 14% of Q4 sales, up 41% sequential (2026-03-27)

Named risks

Auto-cyclicality could repeat FY25's 31% revenue collapse. Severity: high
China exposure (~28% of revenue in late 2025) faces pricing competition. Severity: medium
Renewed acquisition approach from onsemi or another consolidator. Severity: medium
Sanken retains ~32.5% stake and board chair, creating governance overhang. Severity: medium
High stock volatility (52-week range $22.41-$71.77) around earnings and launches. Severity: low
