NEW YORK, Jan 29, 2026, 13:18 EST — Regular session.
Allegro MicroSystems shares climbed roughly 8.5% to $37.50 in Thursday’s afternoon session, buoyed by a sharp rise in quarterly sales and new March-quarter guidance. The chipmaker’s stock fluctuated from $34.56 to $39.75, outpacing the broader semiconductor sector, which dipped. The iShares Semiconductor ETF fell around 0.9%, while auto-focused rivals ON Semiconductor and NXP Semiconductors slid about 4% each.
The results come at a sensitive time for anything linked to autos and factories, where demand can shift rapidly as customers trim inventories. Investors are hunting for clear signals on what reflects genuine end-demand versus mere timing issues.
Allegro sells power and sensing chips for motion control and energy systems, a market tied closely to car and industrial equipment production schedules. Traders often overreact to its updates on orders and backlog, swinging sentiment sharply either way.
Allegro reported fiscal third-quarter net sales climbed 29% year-over-year to $229.2 million, driven by $164.5 million in automotive revenue and $64.7 million from industrial and other segments. Non-GAAP earnings hit $0.15 per share, while GAAP diluted EPS came in at $0.04. The adjusted non-GAAP numbers exclude certain items. Looking ahead to the fourth quarter ending March 27, the company expects sales between $230 million and $240 million, with non-GAAP EPS ranging from $0.14 to $0.18 and a non-GAAP gross margin projected between 49% and 51%. CEO Mike Doogue noted sales “exceed[ed] the high end of our guidance range,” highlighting “growing bookings and backlog.” CFO Derek D’Antilio mentioned a term-loan repricing linked to SOFR, the U.S. dollar benchmark rate.

The March-quarter outlook suggests the company is relying on sustained demand in its key markets, yet it raises the stakes for delivering results in a chip sector known for sudden swings. Investors will be watching closely to see if order momentum holds steady after the initial earnings buzz fades.
Thursday’s price action seemed partly mechanical. The stock swung widely intraday, with options desks pushing sharp moves as they adjusted hedges following earnings.
There is a downside scenario. Allegro pointed out the common pitfalls for chip suppliers: changes in product and customer mix that could squeeze margins, plus any slowdown or disruption in the auto sector.
Next, we turn to longer-term targets. Allegro’s investor calendar marks an Analyst Day on Feb. 18. This event might shift forecasts on automotive electrification, data center exposure, and margin strategies. investors.allegromicro.com
