Filed by NYSE Group, Inc. Pursuant to Rule 425 under the Securities Act of 1933, as amended, and deemed filed pursuant to Rule 14a-12 of the Securities Exchange Act of 1934, as amended Subject Companies: New York Stock Exchange, Inc. Archipelago Holdings, Inc. (Commission File No. 001-32274) Date: October 17, 2005 On October 14, 2005, after the close of business, the New York Stock Exchange, Inc. issued the following bulletin to its members: * * * Special Membership Bulletin [Letterhead of John A. Thain] FROM: John A. Thain DATE: October 14, 2005 RE: Summary of October 6 Member Town Hall Meeting We had a productive Member Town Hall Meeting on October 6 covering three principal topics: a business update, the status of our Hybrid Market, and the Archipelago transaction. As I have in the past, I will summarize the major areas of discussion for the benefit of those who were unable to attend. I would like to begin by reiterating the strategy behind the Archipelago deal. First, we are becoming a public, for-profit company, a transformation which many of you had been advocating, and one that I believe we need to undertake in order to compete with other domestic and international exchanges. We are clearly in a period of consolidation in the global marketplace, and we must have a public currency if we wish to participate in that consolidation. Second, through the acquisition of Archipelago, we are broadening our product mix and providing opportunities for greater revenue growth. Given our existing position in our listings, trading and market data businesses, it is unlikely that our revenues would grow beyond that pace at which the market overall is growing. The acquisition of Arca expands our revenue drivers to include an over-the-counter trading business, options, an improved position in the trading of ETFs, and the ability to develop a fixed income trading business and a second listing brand. We also acquire an entrepreneurial, innovative management team. The market has continued to view this strategy positively. Seats have recently been trading at $2.8 million. With the AX stock price at $37.20, the implied value for each seat in the merger is $3.3 million including the $300,000 cash distribution (but not including any excess cash distribution). The implied market value of the new NYSE Group is $6 billion. The various regulatory filings related to the transaction are proceeding on track. We filed Amendment #1 to the S-4 on September 14 and have received comments back from the SEC. We have provided the complete draft of the 19b-4 to the SEC. The IRS tax ruling and Hart-Scott-Rodino antitrust review are proceeding. We currently hope to finalize the S-4 by the end of October and schedule a Member meeting and vote for late November. The timing is, of course, subject to SEC approval. Based on meetings with institutional investors and capital market representatives from the various broker-dealers, we believe there will be considerable interest on the part of investors in owning shares of the NYSE Group. We have been advised, subject to market conditions, that a successful secondary offering of $1 billion to $2 billion could be accomplished shortly after the closing of the deal. This would give Members significant liquidity much sooner than the expiration of the lock-ups. We reviewed the status of the litigation by the small group of Members seeking to deny you the right to vote on this transaction. We were unsuccessful in our attempt to have this litigation dismissed. Therefore, we are in the document production and deposition process, leading to a potential hearing in mid-November. We continue to believe that this lawsuit is without merit and will result only in our having less excess cash to distribute to the Members. We do not believe that you should be denied your right to vote. We discussed my June meeting with representatives of Bain and Blackstone. No offer was made by this group. We are not seeking capital or a minority investor. An equity investor would not further our strategy of becoming a public company and broadening our product mix. We are not seeking to sell the NYSE. We were approached by a Member seeking permission to utilize a Grantor Retained Annuity Trust ("GRAT") as an estate-planning vehicle for his seat. There is potentially a significant benefit, given the current level of seat prices, to utilizing a GRAT prior to the transaction closing. This would require a two-step process: first transfer of the seat to an LLC, then transfer of the LLC interests to a GRAT. While we will not provide tax or legal advice on this process (you must consult your own tax and legal advisors) and our ability to permit these transfers is subject to SEC approval, we will facilitate the process if you wish to pursue this idea. We want to continue to be responsive to the views and ideas of our Members. You may have your tax or legal advisors contact Rich Bernard (212-656-2222) at the Exchange. Development of the NYSE Hybrid Market continues on track. We have sent Amendment #7 of the Hybrid Market filing to the SEC, and are continuing to develop and roll out the technology that will support it. We have heard concerns from the floor about effectuating and reporting floor trades in the Hybrid market, and a special subcommittee of the Technology Policy and Oversight Committee has been established to address the issue. A new floor broker organization, the Independent Broker Action Committee ("IBAC") has been established, in addition to the two existing organizations, to address concerns about the auction market. We continue to believe that the price discovery process of the auction market is core to the value proposition of the NYSE, and that the Hybrid Market will give specialists and brokers powerful new tools to represent their customers and discover prices at the point of sale. The Exchange's business continues to be strong. We have had 111 listings to date, putting us 11% ahead of 2004. The listings include 71 operating companies, 36 closed end funds, and four ETFs. Our share of trading has trended downward slightly, due primarily to a loss of share in high-volume, low-priced stocks and a change in Nasdaq's rules requiring off-hours trades to be printed to the tape. We are considering a variety of options for addressing that decrease in share. We are on track to exceed our net income targets for the year, and have already identified most of the $100 million in 2005-06 expense reduction we committed to achieve. Marsh Carter discussed the question several of you had raised about representation of current NYSE Members on the NYSE Board of Directors. Under our current Constitution, Members are prohibited from serving on the Board. Post-merger, we will be subject to the SEC's and the NYSE's Board independence requirements, which would not preclude shareholders from Board service by virtue of their ownership of NYSE Group shares. Marsh noted there were currently two vacancies on the NYSE Board and that Dr. Alice Rivlin, who heads the Board's Nominating and Governance Committee, was seeking qualified candidates. If you wish to recommend a qualified candidate to the Nominating Committee, please direct that recommendation to Mary Yeager, Acting Corporate Secretary (212-656-2062), who will provide it to Dr. Rivlin and her Committee. As always, we welcome your input and appreciate your support.
