BIOLASE Urges Stockholders To Vote Today "FOR" The Reverse Stock Split

The Adjourned BIOLASE Special Meeting Reconvenes Tuesday, February 16, 2021

FOOTHILL RANCH, Calif., Feb. 1, 2021 /PRNewswire/ -- BIOLASE, Inc. (NASDAQ: BIOL), the global leader in dental lasers, encourages stockholders to vote their shares with respect to the adjourned special meeting of stockholders initially held on January 22, 2021 (the "Special Meeting"), which will reconvene on Tuesday, February 16, 2021. Stockholders are urged to vote TODAY.

Vote "FOR" the Reverse Stock Split.

At the time the Special Meeting was originally convened, there were insufficient votes to approve Proposal 1, which sought approval to amend the Company's Restated Certificate of Incorporation to effect a reverse stock split of the Company's common stock and reduce the authorized shares of common stock at a ratio of 1-for-25, if and when determined by the Company's board of directors. The meeting was adjourned to allow additional time to solicit additional proxies with respect to this proposal.

The Special Meeting will reconvene on February 16, 2021 at 7:00 a.m. Pacific Time at the Company's corporate headquarters. The record date for the Special Meeting has been changed from December 10, 2020 to January 25, 2021. Stockholders of record at the close of business on January 25, 2021 are entitled to vote at the Special Meeting.

BIOLASE stockholders can vote by following the easy instructions on the proxy card accompanying the proxy materials they receive in the mail. Whether or not they plan to attend the Special Meeting, stockholders are encouraged to vote now online or by telephone to ensure their shares are represented at the Special Meeting.

All previously cast votes associated with the Special Meeting, regardless of which voting method was used, will be valid for the Special Meeting, as long as such votes were cast by stockholders who are also stockholders of record on January 25, 2021. If you previously cast your vote and are also a holder of record on the January 25, 2021, you do not need to vote again unless you wish to change your vote.
