As previously disclosed in a Form 8-K filed by Acacia Research Corporation (the “Company”) on July 31, 2018, Paul Falzone resigned from the Company’s board of directors (the “Board”) effective as of July 25, 2018.

On July 31, 2018, the Company received correspondence from Nasdaq noting that the Company was no longer in compliance with Nasdaq's audit committee composition requirements as set forth in Nasdaq Listing Rule 5605 (the “Notice”). The Notice also stated, among other things, that, pursuant to Nasdaq Listing Rule 5605(c)(4), the Company is entitled to a cure period in order to regain compliance with Nasdaq Listing Rule 5605(c)(2)(A), which cure period will expire upon (i) the earlier of either the date of the Company's next annual shareholders' meeting or July 26, 2019, or (ii) if the next annual shareholders' meeting is held before January 22, 2019, no later than January 22, 2019.
