Adverum Biotechnologies, Inc. (NASDAQ:ADVM) is a biotechnology company focused on developing gene therapies for ocular and rare diseases. On April 2, 2025, Leonard Braden Michael, a significant shareholder with a 10% stake, purchased 15,209 shares of ADVM at $4.04 each. This acquisition increased his total ownership to 2,757,526 shares, reflecting confidence in the company’s potential.

Despite this insider purchase, Adverum faces scrutiny as Levi & Korsinsky investigates potential federal securities law violations. The company disclosed to the SEC on March 31, 2025, that certain financial statements should not be relied upon due to non-cash accounting errors related to tenant improvement allowances in North Carolina. Consequently, Adverum plans to restate its financials for 2022 and 2023.

The stock price of NASDAQ:ADVM, currently at $4.26, has seen an 11.23% increase, rising by $0.43. Today, the stock fluctuated between $3.87 and $4.39. Over the past year, it reached a high of $14.16 and a low of $3.52. The company’s market capitalization is approximately $88.62 million, with a trading volume of 153,684 shares.

These financial restatements could impact investor confidence and stock performance. However, Leonard Braden Michael’s recent purchase might suggest optimism about Adverum’s future prospects. Investors should monitor the investigation’s outcome and the company’s efforts to address these accounting issues.
