ABOUT THIS PROSPECTUS

This prospectus is a part of a registration statement that we filed with the Securities and Exchange Commission (the “SEC”) using a “shelf” registration process. Under this shelf registration process, we may, from time to time, offer any combination of the securities described in this prospectus in one or more offerings.

This prospectus provides you with a general description of each of the securities we may offer. Each time we sell securities, we will provide one or more prospectus supplements, together with one or more pricing supplements, underlying supplements, product supplements and/or other types of offering documents or supplements (together referred to herein as a “prospectus supplement”) that will contain specific information about the terms of the offering. The prospectus supplement may also add, update or change the information in this prospectus. You should read both this prospectus and the accompanying prospectus supplement together with additional information described under the heading “Where You Can Find More Information,” beginning on page 2 of this prospectus.

We have not authorized anyone to provide you with any information other than that contained or incorporated by reference in this prospectus or the accompanying prospectus supplement. We take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. This prospectus and the accompanying prospectus supplement do not constitute an offer to sell or the solicitation of an offer to buy any securities other than the securities described in the accompanying prospectus supplement or an offer to sell or the solicitation of an offer to buy such securities in any circumstances under which such offer or sale is unlawful.

Neither the delivery of this prospectus or the accompanying prospectus supplement, nor any sale made hereunder or thereunder shall, under any circumstances, create any implication that there has been no change in the affairs of First Commonwealth Financial Corporation since the date hereof or that the information contained or incorporated by reference herein or therein is correct as of any time subsequent to the date of such information. You should not assume that the information in or incorporated by reference in this prospectus or any accompanying prospectus supplement prepared by us is accurate as of any date other than the date(s) on the front covers of those documents, regardless of when this prospectus is delivered or when any sale of our securities occurs. Our business, financial condition, results of operations and prospects may have changed since those dates.

The registration statement containing this prospectus, including the exhibits to the registration statement, provides additional information about us and the securities offered under this prospectus. The registration statement can be read at the SEC website or at the SEC offices mentioned under the heading “Where You Can Find More Information.”

We may offer and sell securities directly to you, through agents we select or through underwriters or dealers we select. If we, directly or through agents, solicit offers to purchase securities, we reserve the right to accept and, together with our agents, to reject, in whole or in part, any of such offers. The prospectus supplement will contain the names of the underwriters, dealers or agents, if any, together with the terms of offering, the compensation of those underwriters and the net proceeds to us. Any underwriters, dealers or agents participating in the offering may be deemed “underwriters” within the meaning of the Securities Act of 1933.

Unless otherwise indicated or unless the context requires otherwise, all references in this prospectus to “First Commonwealth,” the “Corporation,” “we,” “us,” “our” or similar references mean First Commonwealth Financial Corporation.

RISK FACTORS

An investment in our securities involves risks. Before making an investment decision, you should carefully consider the risks described in the documents incorporated by reference in this prospectus and in any prospectus supplement used in connection with an offering of our securities, including those risks identified under “Risk Factors” in Item 1A of Part I of our Annual Report on Form 10-K for the year ended December 31, 2014, which is incorporated by reference in this prospectus and which may be amended, supplemented or superseded from time to time by other reports that we subsequently file with the SEC. Additional risks, including those that relate to any particular securities we offer, may be included in a prospectus supplement or free writing prospectus that we authorize from time to time, or incorporated by reference into this prospectus or a prospectus supplement.

RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth our historical ratio of earnings to fixed charges and ratio of earnings to combined fixed charges and preferred stock dividends for the periods indicated:

	For the six months ended June 30,		For the years ended December 31,
	2015	2014	2014	2013	2012	2011	2010
Ratio of earnings to fixed charges:
Excluding interest on deposits	11.32	12.65	10.79	9.86	7.29	2.75	2.92
Including interest on deposits	6.02	4.46	4.30	3.59	2.86	1.35	1.37

Note: We calculate our ratio of earnings to fixed charges by adding income before income taxes plus fixed charges and dividing that sum by our fixed charges. Our fixed charges consist of interest expense and the portion of our rental expense deemed to represent interest. We calculate our ratio of earnings to fixed charges and preferred stock dividends by adding income before income taxes plus fixed charges minus preferred stock dividends and dividing that sum by our fixed charges. Our fixed charges for this ratio consist of interest expense, the portion of our rental expense deemed to represent interest, and preferred stock dividends.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.

The estimated expenses in connection with this registration statement, other than underwriting discounts and commissions, are as follows:

SEC registration fee	$	(1	)
Trustee fees	(2		)
Printing expenses	(2		)
Legal and accounting expenses	(2		)
Rating agency fees	(2		)
Miscellaneous	(2		)
TOTAL	$	(2	)

(1)	Deferred pursuant to Rule 456(b) and to be calculated in connection with the offering of securities under this registration statement pursuant to Rule 457(r).
(2)	These fees are calculated based on the numbers of issuances and amount of securities offered and, accordingly, cannot be estimated at this time. An aggregate amount of these expenses will be reflected in the applicable prospectus supplement.

Item 15. Indemnification of Directors and Officers.

Sections 1741 to 1743 of the Pennsylvania Business Corporation Law (the “BCL”) provide that a corporation may indemnify its representatives (including directors and officers) against expenses, judgments, fines and amounts paid in settlement that they incur in such capacities, provided certain standards are met, including good faith and the reasonable belief that the particular action is in, or not opposed to, the best interests of the corporation or, in a criminal proceeding, they had no reasonable cause to believe their conduct was unlawful. In general, this power to indemnify does not exist in the case of actions against a director or officer by or in the right of the corporation if the person seeking indemnification is adjudged liable to the corporation. A corporation is required to indemnify directors and officers against expenses they may incur in defending actions to which they are made a party by reason of their status as directors or officers if they are successful on the merits or otherwise in the defense of such actions.

Section 1746 of the BCL provides that the foregoing provisions shall not be deemed exclusive of any other rights to which a person seeking indemnification may be entitled under, among other things, any provision in the corporation’s articles of incorporation or bylaws, provided that no indemnification may be made in any case where the act or failure to act giving rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness. Article 11 of the Corporation’s Bylaws provides for the indemnification of directors and officers against expenses and liabilities to the fullest extent permitted by law. Any director or officer who is made, or threatened to be made, a party to any claim, action, suit or proceeding by reason of such person being or having been a director or officer of the Corporation or a subsidiary of the Corporation, or by reason of the fact that such person is or was serving at the request of the Corporation as a director, officer, employee, fiduciary or other representative of another corporation or entity, will be entitled to indemnification. The Bylaws further provide that such indemnification is not exclusive of any other rights to which such individual may be entitled.

Article 12 of the Corporation’s Bylaws provides that no director or officer of the Corporation will be liable by reason of having been a director or officer of the Corporation if the person performs his or her duties in good faith and in a manner reasonably believed to be in the best interests of the Corporation. This standard will be satisfied if the person acted without self-dealing, willful misconduct or recklessness.

II-1

The Corporation has obtained and maintains insurance policies covering its officers and directors and indemnifying them against loss on account of certain claims made against them, within the limits and subject to the limitations of such policies. 

Item 16. Exhibits.

A list of exhibits filed herewith is contained in the exhibit index that immediately precedes such exhibits and is incorporated herein by reference.

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) above do not apply if the information required to be included in a post-effective amendment by those clauses is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described in Item 15 above, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities, other than the payment by us of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding, is asserted by such director, officer or controlling person

II-3

in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

(d) To file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act (the “Act”) in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Act.
