Item 8.01. Other Events.

On December 5, 2012, Bottomline Technologies (de), Inc. (“Bottomline”) issued a press release announcing its intention to offer $150 million aggregate principal amount of convertible senior notes due 2017 in an underwritten public offering pursuant to an effective shelf registration statement on file with the Securities and Exchange Commission. Bottomline also expects to grant the underwriters an option to purchase an additional $22.5 million aggregate principal amount of notes, within 30 days of the offering of the notes, to cover over-allotments.

The notes will pay interest semiannually and will be convertible, under specified circumstances or time periods, into cash or a combination of cash and shares of Bottomline’s common stock. Bottomline plans to hold a special meeting of its stockholders on January 17, 2013 at which Bottomline will seek stockholder approval for an amendment to its amended and restated certificate of incorporation to increase the number of authorized shares of its common stock from 50,000,000 to 100,000,000. Prior to obtaining that stockholder approval, Bottomline will satisfy its conversion obligation solely in cash. Following stockholder approval, Bottomline may deliver cash or a combination of cash and shares of Bottomline’s common stock, at Bottomline’s election, upon conversion of the notes. The completion of Bottomline’s offering of notes is not conditioned on stockholder approval of the increase in the number of authorized shares of common stock, and stockholder approval of such increase will not be conditioned on completion of the offering.

The notes will mature on December 1, 2017, unless repurchased or converted in accordance with their terms prior to that date. The company will not have the right to redeem the notes prior to maturity. The interest rate and terms of the notes, including their conversion rate, will be determined by negotiations among the company and the underwriters.

If certain conditions are met, including the company’s stock price exceeding 130% of the conversion price of the notes during certain specified periods, and during the six months before maturity of the notes regardless of whether such conditions are met, the notes would be convertible into cash or a combination of cash and shares of the company’s common stock. However, prior to obtaining stockholder approval for the increase in the number of authorized shares of the company’s common stock as described above, the company will satisfy its conversion obligations solely in cash. To help minimize dilution to existing stockholders and/or offset potential cash payments in excess of the principal amount of the notes upon their conversion, the company plans to enter into privately negotiated hedge transactions. The company also plans to enter into separate privately negotiated warrant transactions that could have a dilutive effect on the company’s common stock to the extent that the market price of the company’s common stock exceeds the warrants’ exercise price (which is expected to be significantly higher than the conversion price). However, under certain circumstances, the company may elect to settle all of the warrants in cash. The net effect of the hedge and warrant transactions, if they are settled through delivery of the company’s common stock, is generally intended to be an increase in the company’s stock price beyond which the company’s common stock would be diluted. The counterparties to the hedge and warrant transactions may include the underwriters in the offering or their affiliates.

Bottomline intends to use a portion of the net proceeds of the offering for general corporate purposes, which may include the acquisition of companies, businesses or assets, or working capital. In addition, the company intends to use a portion of the net proceeds of the offering to fund the cost to it of the hedge transactions described above.

In connection with the hedge and warrant transactions the company is entering into, the counterparties (or their affiliates) expect to enter into various derivative transactions with respect to the company’s common stock concurrently with or shortly after the expected pricing of the notes. This activity could increase (or reduce the size of any decrease in) the market price of the company’s common stock or the notes at that time. In addition, the counterparties or their affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to the company’s common stock and/or purchasing or selling the company’s common stock or other securities of the company in secondary market transactions following the expected pricing of the notes and prior to the expected maturity of the notes (and are likely to do so during any observation period related to a conversion of notes). This activity could also cause or avoid an increase or a decrease in the market price of the company’s common stock or the notes.

This Form 8-K is neither an offer to sell nor a solicitation of an offer to buy the securities described herein, nor shall there be any sale of these securities in any jurisdiction in which such an offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. The offering of the notes will be made only by means of a prospectus supplement and related prospectus. The hedge and warrant transactions described above and the shares of the company’s common stock underlying the warrant transactions have not been and will not be registered under the Securities Act of 1933, as amended, or the securities laws of any other jurisdiction and may not be offered or sold in the United States without registration or an applicable exemption from registration requirements.

RBC Capital Markets (Sole Coordinator) and RBS are acting as joint book-running managers for the offering. Bottomline has filed a registration statement (including a base prospectus and related preliminary prospectus supplement) with the SEC for the offering. You may get these documents for free by visiting EDGAR on the SEC web site at www.sec.gov. Alternatively, Bottomline, the underwriter or any dealer participating in the offering will arrange to send you the preliminary prospectus supplement and the accompanying prospectus if you request them by contacting RBC Capital Markets, LLC, 3 World Financial Center, 200 Vesey Street, 8th Floor, New York, NY 10281-8098; Attention: Equity Syndicate; Phone: 877-822-4089; Fax: 212-428-6260 or RBS Americas HQ, 600 Washington Boulevard, Stamford, CT 06901; Attention: Equity Prospectus Library; Phone: 203-897-9874; Email: equity.prospectus@rbs.com.
