The combined company would be domiciled in Ireland.

(Bloomberg) — Towers Watson & Co. (NYSE:TW) investors should reject a planned merger with insurance broker Willis Group Holdings PLC, proxy advisers Institutional Shareholder Services and Glass Lewis & Co. said.

The consulting firm’s holders should seek improved merger terms, or “the better option at this time is to remain a standalone company,” Glass Lewis said in its report late Thursday. Shares of Towers Watson had dropped when the deal was announced in June.

Both companies’ investors are scheduled to vote on the deal Nov. 18. Willis agreed to merge with Towers Watson in an $8.7 billion transaction to add consulting operations, helping it compete against diversified insurance-broker rivals Aon PLC (NYSE:AON) and Marsh & McLennan Cos. (NYSE:MMC). Willis investors would own 50.1 percent of the combined company, to be domiciled in Ireland and led by Towers Watson CEO John Haley. Towers Watson holders would get 2.649 Willis shares and a one-time cash dividend of $4.87 for each share they own.

“Although Towers shareholders might be willing to forgo a premium in exchange for the potential benefits of this transaction, the magnitude of the discount they are being asked to accept appears excessive,” ISS said in its report.

‘Revenue synergies’

Towers Watson disagrees with the advisers because they focus on short-term trading and discount the “significant” long-term value creation potential of the merger, the company said on Friday. London-based Willis said in a statement that the recommendation “neglects the estimated $4.7 billion in incremental value for shareholders that we expect through clearly identified cost, tax and revenue synergies.”

Willis dropped 68 cents, or 1.5 percent, to $44.60 at 9:39 a.m. in New York trading. Towers Watson slipped 0.1 percent to $129.02, compared with the closing price of $137.98 the day before the deal was announced.

Towers Watson stakeholders including Driehaus Capital Management LLC, which owns more than 1 million shares, have said they’re planning to vote against the proposed deal, and that the consulting company’s quarterly results, announced Monday, highlight its prospects as an independent firm.

“They came out with fantastic earnings that handily exceeded market expectations,” Matthew Schoenfeld, an assistant portfolio manager at Driehaus, said in a phone interview Friday. “It’s not in the best interest of shareholders to sell at a 9 percent discount to market value for a company that is exceeding expectations and that is doing quite well.”
