5 terms

independent director financial

"announced the appointment of Robert J. Willett to Allegro’s Board of Directors (“Board”) as an independent director"

An independent director is a member of a company's board of directors who is not involved in the company's day-to-day operations and has no significant relationships with the company that could influence their judgment. Their role is to provide unbiased oversight and ensure the company is managed in the best interests of all shareholders. This helps build trust and confidence among investors by promoting transparency and accountability.

audit committee financial expert financial

"that Mr. Willett qualifies as an “audit committee financial expert” as defined by the applicable Securities and Exchange Commission"

A person on a company’s board who has deep knowledge of accounting, financial reporting and auditing, able to understand and question the books, controls and audit work like a trained mechanic inspecting an engine. Investors care because that expertise helps spot errors, weaknesses or misleading statements early, improving the likelihood that financial reports are accurate and reducing the risk of surprises that can hurt a company’s value.

Regulation FD Disclosure regulatory

"Item 7.01 Regulation FD Disclosure. A copy of the Company’s press release"

Regulation FD disclosure requires public companies to share important, market-moving information with everyone at the same time instead of tipping off analysts or large investors first. Think of it as making sure all players on a field hear the same announcement simultaneously; that fairness helps investors trust that stock prices reflect the same information and reduces the risk of sudden, unfair trading advantages or regulatory penalties for selective leaks.

emerging growth company regulatory

"405 of this chapter) or Rule 12b-2 of the Securities Exchange Act of 1934 (§ 240.12b-2 of this chapter). Emerging growth company"

An emerging growth company is a recently public or smaller public firm that qualifies for temporary, lighter regulatory and disclosure rules to reduce the cost and effort of being public. For investors, it means the company may provide less historical financial detail and face fewer reporting requirements than larger firms, so it can grow more quickly but also carries higher uncertainty—like buying a promising early-stage product with fewer user reviews.

forward-looking statements regulatory

"This press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

On May 13, 2026, at the recommendation of the Board’s Nominating and Governance Committee and in accordance with the Second Amended and Restated Stockholders Agreement, dated as of July 29, 2024, by and among the Company, and Sanken Electric Co., Ltd., the Board took the following actions, each of which was effective May 13, 2026: (i) expanded the size of the Board to ten, (ii) elected Robert J.

The Board has also determined that Mr. Willett meets the enhanced independence requirements for audit committee members under Rule 10A-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules of The Nasdaq Stock Market, and that Mr. Willett qualifies as an “audit committee financial expert” as defined by the applicable Securities and Exchange Commission (“SEC”) regulations. The Board has further determined that Mr. Willett meets the enhanced independence requirements for compensation committee members under the rules of The Nasdaq Stock Market.

In connection with his election, the Company entered into an indemnification agreement with Mr. Willett providing for the indemnification of and advancement of expenses permitted by Delaware law for claims, suits or proceedings arising out of a director’s service to the Company.

Mr. Willett will receive the same fees for his service on the Board and its committees as the Company’s other non-employee directors, in accordance with the Company’s director compensation program. The Company’s current director compensation program was filed as an exhibit to the Company’s Quarterly Report on Form 10-Q filed with the SEC on January 30, 2026.
