Item 8.01 Other Events.
On February 22, 2017, the selling securityholders (as defined below) agreed to purchase $143,750,000 aggregate principal amount of 2014 Series A 2.00%
remarketable junior subordinated notes due 2022 (the Junior Notes) of Spire Inc. (Spire) in connection with the remarketing of the junior subordinated notes comprising a component of the equity units originally issued in June
2014 pursuant to the Purchase Contract and Pledge Agreement (the Purchase Contract and Pledge Agreement), dated as of June 11, 2014, between Spire and U.S. Bank National Association, as purchase contract agent, attorney-in-fact of
the holders of certain purchase contracts, collateral agent, custodial agent and securities intermediary.
Also on February 22, 2017, Spire entered
into a Securities Purchase and Registration Rights Agreement (the SPRRA), among Spire and the several purchasers named therein (the selling securityholders), pursuant to which the selling securityholders agreed to sell the
Junior Notes to Spire on or about February 27, 2017 in exchange for $143,750,000 aggregate principal amount of 3.543% Senior Notes due 2024 (the Senior Notes) of Spire and a cash payment.
The SPRRA granted the selling securityholders the right, by written notice to Spire, to offer the Senior Notes to the public in secondary public offerings
from time to time. Each of the selling securityholders delivered a public offer notice to Spire on February 22, 2017 with respect to all the Senior Notes they held. On February 22, 2017, Spire entered into an underwriting agreement (the
Underwriting Agreement) with the selling securityholders and the several underwriters named therein in connection with the public offering (the Public Offering) of $150,000,000 aggregate principal amount of Senior Notes
consisting of $6,250,000 aggregate principal amount of the Senior Notes issued and sold by Spire and $143,750,000 aggregate principal amount of the Senior Notes sold by the selling securityholders.
The Public Offering was completed on February 27, 2017. Spire intends to use the net proceeds from its sale of the Senior Notes to repay short-term debt.
Spire did not receive any proceeds from the sale of the Senior Notes by the selling securityholders. The sum of the amount received by the selling securityholders for the Senior Notes in the Public Offering and the amount of cash the selling
securityholders received from Spire pursuant to the SPRRA is equal to the purchase price of the Junior Notes purchased by such selling securityholders in the remarketing transaction. Copies of the SPRRA and the Underwriting Agreement are filed as
Exhibits 1.1 and 1.2 to this Current Report, respectively, and are expressly incorporated by reference herein and into the Registration Statement on Form S-3 (Registration No. 333-213759) (the Registration Statement) of Spire which
became automatically effective upon filing with the Securities and Exchange Commission on September 23, 2016. The foregoing descriptions of the SPRRA and the Underwriting Agreement are qualified in their entirety by reference to these exhibits.
