Rigrodsky & Long, P.A. announces that it is investigating potential claims against the board of directors of WCA Waste Corporation (“WCA” or the “Company”) (Nasdaq: WCAA) concerning possible breaches of fiduciary duty and other violations of law related to the Company’s entry into an agreement to be acquired and taken private by Macquarie Infrastructure Partners II (“Macquarie”) in a transaction with an approximate value of $526 million.

Under the proposed agreement, Macquarie will acquire all of WCA’s outstanding shares for $6.50 per share in cash.
