El Segundo-based electronics wholesale Bell Industries Inc. has had its bid to acquire Coast Distribution System Inc. rejected by Coast’s board of directors.

Morgan Hill-based Coast, which makes accessories and parts for recreational vehicles and boats, said its board rejected Bell’s unsolicited non-binding offer of $8.10 per share, which had been raised May 5 from a previous offer of $7.70 per share. The board concluded that Coast’s prospects as an independent company “are far superior to Bell’s proposal,” according to a company statement.

“Coast’s board will vigorously oppose any efforts by Bell to take advantage of our stockholders,” Chief Executive Thomas McGuire said. “Our stockholders have been loyal to us and we intend to protect their interests to the fullest.”

Bell Chief Executive John A. Fellow had said in an earlier letter to the company that Bell “wouldn’t hesitate” to nominate two directors who support Bell’s takeover offer to Coast’s board at its annual shareholders’ meeting, if Bell did not receive a favorable response to its overture.
