Item 1. Security and Issuer

The title and class of equity security to which this statement on Schedule 13D relates is the Voting Common Stock, no par value (the “Voting Common Stock”) of Trinity Capital Corporation (the “Issuer” or the “Company”). The address of the principal executive officer of the Company is 1200 Trinity Drive, Los Alamos, New Mexico 87544. This Amendment No. 1 to Schedule 13D (this “Amendment”) amends and supplements the Schedule 13D filed on December 20, 2016 (as amended, the “Schedule 13D”) with the Securities and Exchange Commission (the “SEC”). This Amendment is being filed to report the transactions described in Item 4 below, and to remove certain individuals as reporting persons (as further described in Item 2). Unless specifically amended hereby, the disclosures set forth in the Schedule 13D remain unchanged.

Item 2. Identity and Background

Item 2 of the Schedule 13D is hereby amended to remove John M. Eggemeyer, J. Mikesell Thomas, Mark G. Merlo and John T. Pietrzak, each of whom are managing principals of Castle Creek Capital VI LLC (“CCC VI”), as reporting persons. Although each of Messrs. Eggemeyer, Thomas, Merlo and Pietrzak were previously included as reporting persons, upon further review, these individuals are not deemed to be beneficial owners of the Voting Common Stock owned by Castle Creek Capital Partners VI, LP (“Fund VI”) and thus have been removed as reporting persons.

Item 4. Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended by adding the following at the end thereof:

Merger Agreement

On November 1, 2018, the Company and its wholly owned subsidiary, Los Alamos National Bank (“LANB”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Enterprise Financial Services Corp (“EFSC”) and its wholly owned subsidiary, Enterprise Bank & Trust (“EB&T”). Subject to the terms and conditions of the Merger Agreement, the Company will merge with and into EFSC, with EFSC being the surviving corporation (the “Merger”). Immediately following the consummation of the Merger, LANB will merge with and into EB&T, with EB&T being the surviving bank.

Under the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each outstanding share of the Voting Common Stock and the Company’s non-voting common stock, no par value (the “Non-Voting Common Stock”), (except for cancelled shares and Dissenting Shares (as defined in the Merger Agreement)) will be converted into the right to receive (i) 0.1972 shares of EFSC’s common stock and (ii) $1.84 in cash, without interest, with any fractional shares paid in cash. Under the Merger Agreement, Tony Scavuzzo, a Principal of CCC VI and current member of the Company’s board of directors, will be appointed to the board of directors of EFSC effective at or immediately following the Effective Time.

The closing of the Merger is subject to customary closing conditions, including among other things approval of the Merger Agreement by the Company’s shareholders and receipt of certain governmental and regulatory consents and approvals.

The foregoing reference to and descriptions of the Merger Agreement and the transactions contemplated thereby do not purport to be complete and are subject to, and are qualified in their entirety by, the full text of the Merger Agreement, which is attached hereto as Exhibit 99.2 and incorporated herein by reference.

Voting Agreement

In connection with the execution of the Merger Agreement, Fund VI entered into a voting agreement (the “Voting Agreement”) with the Company and EFSC. Subject to the terms and conditions of the Voting Agreement, Fund VI agreed, among other things, to vote the shares of Voting Common Stock beneficially owned by Fund VI in favor of the Merger and the Merger Agreement and against any Superior Proposal, Acquisition Proposal (each term as defined in the Merger Agreement) and certain other actions. In connection therewith, Fund VI appointed EFSC as its proxy and attorney-in-fact to vote or act by written consent in accordance with the Voting Agreement.

Pursuant to the Voting Agreement, Fund VI is subject to certain restrictions regarding transferring or encumbering, or entering into any other voting arrangements with respect to, the Voting Common Stock held by Fund VI. Fund VI also waived any appraisal or dissenters’ rights in connection with the Merger. The Voting Agreement will terminate upon the earliest to occur of (i) the effective time of the Merger, (ii) the date on which the Merger Agreement is terminated in accordance with its terms and (iii) upon any modification, waiver or amendment of the Merger Agreement that either materially adversely affects Fund VI or adversely affects the consideration payable to the Company’s shareholders.

The foregoing reference to and descriptions of the Voting Agreement and the transactions contemplated thereby do not purport to be complete and are subject to, and are qualified in their entirety by, the full text of the Voting Agreement, which is attached hereto as Exhibit 99.3 and incorporated herein by reference.

Item 5. Interest in Securities of the Issuer

Items 5(a) and (b) of the Schedule 13D are hereby amended and restated, with effect from the date of the event giving rise to this Amendment, with the following:

Reporting Person	Amount Beneficially Owned	Percent of Class (3)		Sole Power to Vote or Direct the Vote	Shared Power to Vote or Direct the Vote	Sole Power to Dispose or to Direct the Disposition	Shared Power to Dispose or Direct the Disposition

Castle Creek Capital VI LLC (2)	1,151,475	9.9	%	0	1,151,475	0	1,151,475

(1) Excludes 3,901,192 shares of Non-Voting Common Stock owned by Fund VI.

(2) CCC VI disclaims beneficial ownership of the Voting Common Stock owned by Fund VI, except to the extent of its pecuniary interest therein.

(3) This calculation is based on 11,660,491 shares of Voting Common Stock outstanding as of November 1, 2018, based on information provided in the Merger Agreement.
