Lawsuit alleges problems were disclosed too late
Robbins LLP, a law firm specializing in shareholder rights, said on November 3 that a class action lawsuit had been filed against Alphabet Inc. The action was brought on behalf of investors who purchased or otherwise acquired Alphabet securities traded on the Nasdaq under the symbols GOOG or GOOGL between May 19 and July 16, 2026.
The lawsuit alleges that Alphabet failed to timely disclose to investors that the training results for Gemini 3.5 Pro were disappointing. The plaintiff claims this could have significantly delayed the model's planned launch.
Alphabet held its annual Google I/O developer conference on May 19. According to the announcement, Sundar Pichai, the company's CEO, announced at the event that Gemini 3.5 Pro would be released in June. The lawsuit examines this timing and subsequent developments as part of the investor disclosures.
Share price fell in response to the news
Robbins LLP's statement cites a July 16 report by Bloomberg. The report said Google was months behind schedule in delivering Gemini 3.5 Pro, the company's most powerful flagship artificial intelligence model, while continuing to work on the code.
According to information cited by Bloomberg, Google changed the data used to train Gemini at the end of the previous month to improve the model's capabilities, but the results were disappointing. Robbins LLP said that after the news became public, Alphabet's Class A common stock fell $16.46, or 4.4 percent, to $354.46 on July 16. The price of the Class C shares declined by $16.39, also 4.4 percent, to $353.58. The statement also mentioned unusually high trading volume.
The allegations in the lawsuit may be examined by the court during the proceedings. Robbins LLP's statement itself notes that past results do not guarantee a similar outcome.
Affected investors can come forward by November 30
Investors who purchased Alphabet securities during the specified period and suffered significant losses can contact Robbins LLP by November 30. The deadline relates to applying for the role of lead plaintiff.
The lead plaintiff is an investor appointed by the court to represent the interests of the entire class during the lawsuit. According to the statement, being appointed lead plaintiff is not a prerequisite for receiving a share of any potential recovery. Investors who do not seek the role may participate in the proceedings as absent class members.
Robbins LLP said there is no upfront cost to participating because the firm represents investors on a contingency-fee basis. Further information is available by contacting the firm, emailing attorney Aaron Dumas Jr., or calling (800) 350-6003. Brian J. Robbins, the firm's founding partner, said, “Companies are required to provide investors with complete and accurate information so that markets can operate fairly and efficiently.”
