Exhibit 99.1

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

Capitalized terms used but not defined in this Exhibit 99.1 shall have the meanings ascribed to the in the Current Report on Form 8-K to which the Exhibit 99.1 is attached.

The following unaudited pro forma condensed combined balance sheet of the Combined Company (as defined below) as of September 30, 2020 and the unaudited pro forma condensed combined statements of operations of the Combined Company for the year ended December 31, 2019 and for the nine months ended September 30, 2020 present the combination of the financial information of South Mountain and Billtrust, after giving effect to the Business Combination, accounted for as a reverse recapitalization, and related adjustments described in the accompanying notes. In connection with the closing of the Business Combination, accounted for as a reverse recapitalization, the registrant changed its name from South Mountain Merger Corp. to BTRS Holdings Inc. (the “Combined Company”).

The unaudited pro forma condensed combined statements of operations for the year ended December 31, 2019 and for the nine months ended September 30, 2020 give pro forma effect to the Business Combination, accounted for as a reverse recapitalization, as if it had occurred on January 1, 2019. The unaudited pro forma condensed combined balance sheet as of September 30, 2020 gives pro forma effect to the Business Combination, accounted for as a reverse recapitalization, as if it was completed on September 30, 2020.

The unaudited pro forma condensed combined financial information is based on and should be read in conjunction with:
 

the accompanying notes to the unaudited pro forma condensed combined financial statements;


the historical unaudited interim financial statements of South Mountain as of September 30, 2020, and for the nine months ended September 30, 2020, and the historical audited financial statements of South Mountain as of December 31, 2019, and for the period from February 28, 2019 (inception) through December 31, 2019, and the related notes, in each case, included elsewhere in this Current Report on Form 8-K or in the Proxy Statement;


the historical unaudited condensed financial statements of Billtrust as of September 30, 2020, and for the nine months ended September 30, 2020, and the historical consolidated financial statements of Billtrust as of and for the year ended December 31, 2019, and the related notes, in each case, included elsewhere in this Current Report on Form 8-K or in the Proxy Statement; and


other information relating to South Mountain and Billtrust contained in this Current Report on Form 8-K or in the Proxy Statement, including the BCA and the description of certain terms thereof set forth under “The Business Combination Agreement,” as well as the disclosures contained in the sections titled “South Mountain Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Billtrust’s Management’s Discussion and Analysis of Financial Condition and Results of Operations”.

The unaudited pro forma condensed combined financial statements have been presented for illustrative purposes only and do not necessarily reflect what the Combined Company’s financial condition or results of operations would have been had the Business Combination, which is accounted for as a reverse recapitalization, occurred on the dates indicated. Further, the unaudited pro forma condensed combined financial information also may not be useful in predicting the future financial condition and results of operations of the Combined Company. The actual financial position and results of operations may differ significantly from the pro forma amounts reflected herein due to a variety of factors. The unaudited pro forma adjustments represent management’s estimates based on information available as of the date of these unaudited pro forma condensed combined financial statements and are subject to change as additional information becomes available and analyses are performed.
 
On January 12, 2021, Billtrust consummated the previously announced Business Combination pursuant to the Agreement dated October 18, 2020 and amended as of December 13, 2020, between South Mountain, First Merger Sub, BT Merger Sub II, LLC and Billtrust, under the terms of which: (i) First Merger Sub, a wholly owned subsidiary of South Mountain merged with and into Billtrust (the “First Merger”), with Billtrust being the surviving company of the First Merger as a wholly owned subsidiary of South Mountain (Billtrust, in its capacity as the surviving corporation of the First Merger, is sometimes referred to as the “Surviving Corporation”) and (ii)  following the First Merger Billtrust merged with and into Second Merger Sub, a wholly owned subsidiary of South Mountain (the “Second Merger,” and together with the First Merger, the “Mergers”), with Second Merger Sub being the surviving entity of the Second Merger. After giving effect to the Mergers, the Combined Company owns, directly, all of the issued and outstanding equity interests of Billtrust, and the pre-Business Combination stockholders of Billtrust hold a portion of the South Mountain Class A Common Stock and all of the South Mountain Class C Common Stock.
 
As part of the Business Combination, accounted for as a reverse recapitalization, each existing share of Billtrust Common Stock, including shares of Billtrust Preferred Stock that were converted into Billtrust Common Stock as part of the Business Combination, accounted for as a reverse recapitalization, was converted into 7.228 shares of South Mountain Class A Common Stock or South Mountain Class C Common Stock, as applicable.

The following pro forma condensed combined financial statements presented herein reflect the actual redemption of 2,015 shares of Class A Common Stock of South Mountain’s stockholders in conjunction with the shareholder vote on the Business Combination contemplated by the Agreement at a meeting held on January 12, 2021.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

Note 1—Description of the Business Combination

On January 12, 2021, Billtrust consummated the previously announced Business Combination pursuant to the Agreement dated October 18, 2020 and amended as of December 13, 2020, between South Mountain, First Merger Sub, BT Merger Sub II, LLC and Billtrust, under the terms of which: (i) First Merger Sub merged with and into Billtrust (the “First Merger”), with Billtrust being the surviving company of the First Merger and (ii) immediately following the First Merger Billtrust merged with and into Second Merger Sub, with Second Merger Sub being the surviving entity of the Second Merger. After giving effect to the Mergers, the Combined Company owns, directly, all of the issued and outstanding equity interests of Billtrust, and the pre-Business Combination stockholders of Billtrust hold a portion of the Combined Company Class A Common Stock and all of the Combined Company Class C Common Stock.

As a result of the Agreement, Billtrust stockholders received aggregate consideration with a value equal to $1,189,502,229, which consists of (i) $90,061,329 in cash at Closing of the Business Combination, accounted for as a reverse recapitalization, and (ii) $1,099,440,900 in South Mountain Class A Common Stock and South Mountain Class C Common Stock at Closing of the Business Combination, accounted for as a reverse recapitalization, or 109,944,090 shares based on an assumed share price of $10 per share.

In connection with the Business Combination, accounted for as a reverse recapitalization, Billtrust stockholders will receive contingent consideration of up to 12,000,000 shares of South Mountain Class A Common Stock or South Mountain Class C Common Stock, as applicable (“Earnout Securities”), contingent upon achieving certain market share price milestones within a period of five years post Business Combination.

In connection with the Business Combination, accounted for as a reverse recapitalization, 1,875,000 shares of South Mountain Class A Common Stock previously issued to the Sponsor and its affiliates in exchange of the founder shares (“Sponsor Vesting Shares”) were placed in a lock-up and will be released from a lock-up upon achieving certain market share price milestones within a period of five years post-Closing. These shares will be forfeited if the set milestones are not reached (see Note 3(d) Impact on equity).

At the Closing, Sponsor forfeited 1,250,000 shares of its South Mountain Class B Common Stock that it owned as of the Closing.

The following table summarizes the pro forma share of the Combined Company Class A Common Stock outstanding after giving effect to the Business Combination, excluding the potential dilutive effect of the Earnout Securities, Sponsor Vesting Shares, and exercise of warrants:

Note 2Basis of presentation

The historical financial information of Billtrust and South Mountain has been adjusted in the unaudited pro forma condensed combined financial information to reflect transaction accounting adjustments related to the Business Combination, accounted for as a reverse capitalization, in accordance with U.S. GAAP. The pro forma adjustments are prepared to illustrate the estimated effect of the Business Combination, accounted for as a reverse recapitalization, and certain other adjustments.

The Business Combination will be accounted for as a reverse recapitalization because Billtrust has been determined to be the accounting acquirer under Financial Accounting Standards Board’s Accounting Standards Codification Topic 805, Business Combinations (“ASC 805”). The determination is primarily based on the evaluation of the following facts and circumstances taken into consideration:
 
Pre-Business Combination stockholders of Billtrust will own a relatively larger portion in the Combined Company compared to the ownership to be held by the pre-Business Combination shareholders of South Mountain;

Billtrust has the right to appoint a majority of BTRS Holdings Inc. Board members;

Senior management of Billtrust will comprise the senior management of the Combined Company; and

The operations of Billtrust prior to the transaction will comprise the only ongoing operations of the Combined Company.

Under the reverse recapitalization model, the Business Combination will be treated as Billtrust issuing equity for the net assets of South Mountain, with no goodwill or intangible assets recorded.
