July 13 (Reuters) - Aeroplane parts maker TransDigm TDG.N said on Monday it was withdrawing from its proposed $960 million acquisition of Stellant Systems, a portfolio company of Arlington Capital Partners.

The company recently concluded that pursuing the transaction through the regulatory review process was no longer in its best interest, TransDigm said in a regulatory filing.

• The Cleveland, Ohio-based manufacturer said it "remains committed to its disciplined acquisition strategy and continues to evaluate acquisition opportunities that it believes will enhance long-term shareholder value."

• The company raised its annual profit forecast in May after posting a better-than-expected quarterly profit on strong aftermarket demand.

• TransDigm develops, manufactures and delivers specialized aircraft components used in almost every commercial and military aircraft in service.

• Defense tech co Stellant designs and makes high-power radio frequency and microwave amplification systems used in military, space, communications, medical and industrial applications.
