prospectus. See “Where You Can Find More Information.”

Q:What is the purpose ofQ:Why am I receiving this proxy statement/prospectus?

A:This proxy statement/prospectus serves as both a proxy statement of Gateway and a prospectus of S&T. As a proxy statement, it is being provided to you because the Gateway board of directors is soliciting your proxy for use at the Gateway special meeting of shareholders at which the Gateway shareholders will consider and vote on (i) adoption of the merger agreement between S&T and Gateway and (ii) authorization of the board of directors to adjourn the special meeting to a later date, if necessary, to solicit additional proxies in favor of adoption of the merger agreement or vote on other matters properly before the special meeting. As a prospectus, it is being provided to you because S&T is offering to exchange shares of its common stock for your shares of Gateway common stock upon completion of the merger.

Q:What is the proposed transaction for which I am being asked to vote?

A:You are being asked to vote upon proposals to (i) adopt thehas entered into an Agreement and Plan of Merger, dated March 29, 2012, by and between S&T and Gateway, whichas of June 5, 2019, with DNB (which, as it may be amended, supplemented or modified from time to time, we refer to as the “merger agreement”). Under the merger agreement, DNB will be merged with and into S&T (which we refer to as the “merger”), with S&T continuing as the surviving corporation (which we refer to as the “surviving corporation”). Immediately following the merger, DNB First, National Association, a wholly owned bank subsidiary of DNB (which we refer to as “DNB Bank”), will merge with and into S&T Bank, S&T’s wholly owned bank subsidiary, with S&T Bank continuing as the surviving bank (which we refer to as the “bank merger”). A copy of the merger agreement is included in this proxy statement/prospectus as Annex A.

The merger cannot be completed unless, among other things, DNB shareholders approve the proposal to approve the merger agreement and the transactions contemplated by the merger agreement (which we refer to as the “DNB merger proposal”).

In addition, DNB is soliciting proxies from its shareholders with respect to two additional proposals, approvals of which are not conditions to the completion of the merger:

a proposal to adjourn the DNB special meeting, if necessary or appropriate, to solicit additional proxies in favor of the DNB merger proposal (which we refer to as the “DNB adjournment proposal”); and
a proposal to adopt an advisory (non-binding) resolution approving the compensation that certain executive officers of DNB may receive in connection with the merger pursuant to agreements or arrangements with DNB (which we refer to as the “DNB compensation proposal”).

DNB will hold a special meeting of shareholders to obtain these approvals (which we refer to as the “DNB special meeting”). This proxy statement/prospectus contains important information about the merger and the other proposals being voted on at the special meeting. You should read it carefully and in its entirety. The enclosed materials allow you to have your shares voted by proxy without attending the DNB special meeting. Your vote is important. We encourage you to submit your proxy as soon as possible.

This proxy statement/prospectus constitutes both a proxy statement of DNB and a prospectus of S&T. It is a proxy statement because the board of directors of DNB is soliciting proxies using this proxy statement/prospectus from DNB shareholders. It is a prospectus because S&T, in connection with the merger, is offering shares of its common stock in exchange for outstanding shares of DNB common stock in the merger.

Q:What will I receive in the merger?

Q:What is the vote required to approve each proposal?
A:Approval of the DNB merger proposal requires the affirmative vote of a majority of the outstanding shares of DNB common stock entitled to vote your shares on the merger agreement without instruction from you. You should instructproposal. If you mark “ABSTAIN” on your brokerproxy card or when voting by Internet or phone, fail to either submit a proxy or vote your shares, followingin person at the directions your broker provides to you. Please check the voting form used by your broker.

Q:What if IDNB special meeting or fail to instruct my broker?your bank, broker or other nominee how to vote with respect to the DNB merger proposal, it will have the same effect as a vote “AGAINST” the DNB merger proposal.

Approval of each of the DNB adjournment proposal and the DNB compensation proposal requires the affirmative vote of the holders of a majority of the votes cast by holders of DNB common stock entitled to vote at the DNB special meeting.

Q:Will my vote affect the amounts that certain executive officers of DNB may receive in connection with the merger?
A:Certain of DNB’s executive officers are entitled, pursuant to the terms of their existing compensation arrangements with DNB, to receive certain payments in connection with the merger. If the merger is completed, S&T, as successor to DNB, is contractually obligated to make these payments to these executives (under certain circumstances). Accordingly, even if the DNB shareholders vote not to approve these payments, the compensation will be payable, subject to the terms and conditions of the arrangements and the merger agreement. DNB is seeking your approval of these payments on an advisory (non-binding) basis in order to comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and related SEC rules.
Q:Why is my vote important?
A:If you do not providereturn your proxy, it will be more difficult for DNB to obtain the necessary quorum to hold its special meeting. In addition, your failure to submit a proxy or vote in person, or failure to instruct your bank, broker with instructions, your broker generally will not be permittedor other nominee how to vote, or your shares onabstention will have the merger proposal, which is referred tosame effect as a “broker non-vote.” For purposesvote “AGAINST” approval of determining the numberDNB merger proposal.

The DNB merger proposal must be approved by the affirmative vote of at least a majority of the outstanding shares of DNB common stock entitled to vote on the merger agreement.

The DNB board of directors unanimously recommend that you vote “FOR” the merger proposal.

Q:If my shares of votes castcommon stock are held in “street name” by my bank, broker or other nominee, will my bank, broker or other nominee automatically vote my shares for me?
A:No. Under stock exchange rules, banks, brokers and other nominees who hold shares of DNB common stock in “street name” for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, banks, brokers and other nominees are not allowed to exercise their voting discretion with respect to the approval of matters determined to be “non-routine,” without specific instructions from the beneficial owner. Broker non-votes are shares held by a bank, broker or other nominee that are represented at the DNB special meeting, but with respect to which the bank, broker or other nominee is not instructed by the beneficial owner of such shares to vote on the particular proposal, and the bank, broker or other nominee does not have discretionary voting power on such proposal. If your bank, broker or other nominee holds your shares of DNB common stock in “street name,” your bank, broker or other nominee will vote your shares of DNB common stock only if you provide instructions on how to vote by filling out the voter instruction form sent to you by your bank, broker or other nominee with this proxy statement/prospectus. We believe that the DNB merger proposal, only those votes cast “for” or “against” the DNB adjournment proposal and the DNB compensation proposal are counted. “Broker non-votes,” if any are submitted by brokers“non-routine” proposals, and your bank, broker or nominees in connection with the special meeting, will not be counted as votes “for” or “against” for purposesother nominee can vote your shares of determining the number of votes cast (thus having the effect of a vote against the proposal to adopt the merger agreement), but will be treated as present for quorum purposes.

Q:When and where is the Gateway special meeting of shareholders?

A:Q:If you are unable to locate your original Gateway stock certificate(s), you should contact Robert Kerr, Secretary of Gateway, at 724-942-2021.

Q:Why is my vote important?

A:

Because the merger cannot be completed without the affirmative vote of 66 2/3% of the votes cast by all shareholders entitled to vote to adopt the merger agreement, and because a majority of the outstanding Gateway common stock entitled to vote is necessary to constitute a quorum in order to transact business at the special meeting, every shareholder’s vote is important.

Q:How does the Gateway board of directors recommend that I vote?

A:The Gateway board of directors recommends that you vote “FOR” adoption of the agreement and plan of merger. At the meeting, the members of the board of directors and the executive officers of Gateway, and their affiliates, in the aggregate have the power to vote approximately 25.1% of the outstanding shares of Gateway common stock. Gateway’s directors and executive officers each entered into a voting agreement with S&T in connection with the execution of the merger agreement and therefore will vote their shares in favor of the proposals to be considered at the Gateway special meeting.

Q:Can I attend the Gateway special meeting and vote my shares in person?

A:Yes. All DNB shareholders, including shareholders of record and shareholders who hold their shares through nomineesbanks, brokers or any other holder of record,nominees, are invited to attend the special meeting.

See “Where You Can Find More Information. on page. Each item in this summary refers to the page of this proxy statement/prospectus on which that subject is discussed in more detail.

The Merger and the Merger Agreement (Page 33)

The terms and conditions of the merger are contained in the merger agreement, a copy of which is attached as Annex A to this proxy statement/prospectus. We encourage you to read the merger agreement carefully and in its entirety, as it is the legal document that governs the merger.

Pursuant to the merger agreement, DNB will merge with and into S&T, with S&T continuing as the surviving corporation. Immediately thereafter, DNB Bank, DNB’s wholly owned banking subsidiary, will merge with and into S&T’s wholly owned banking subsidiary, S&T Bank, with S&T Bank continuing as the surviving bank.

The Merger Consideration (Page 57)

If the merger is completed, DNB common shareholders will receive 1.22 shares of S&T common stock for each share of DNB common stock they hold immediately prior to the merger. S&T will not issue any fractional shares of S&T common stock in the merger. DNB shareholders who otherwise would be entitled to a fraction of a share of S&T common stock will receive an amount in cash (rounded to the nearest whole cent) equal to the product of (x) the fraction of a share of S&T common stock to which the holder would otherwise be entitled and (y) the average closing price per share, rounded to the nearest cent, of S&T common stock on the NASDAQ for the consecutive 10 trading days immediately preceding (but not including) the closing date of the merger.

For example, if you hold 125 shares of DNB common stock, you will receive 152 shares of S&T common stock and a cash payment instead of the 0.5 shares of S&T common stock that you otherwise would have received (125 shares × 1.22 = 152.5 shares).

The market value of the merger consideration will fluctuate with the market price of S&T common stock and will not be known at the time DNB shareholders vote on the merger. Any fluctuation in the market price of S&T common stock after the date of this proxy statement/prospectus will change the value of the shares of S&T common stock that DNB shareholders will receive.

Recommendation of DNB’s Board of Directors (Page 36)

The DNB board of directors unanimously recommends that DNB shareholders vote “FOR” the DNB merger proposal, “FOR” the DNB adjournment proposal and “FOR” the DNB compensation proposal.

The DNB board of directors has determined that the merger agreement and the merger are advisable and in the best interests of DNB and its shareholders and has unanimously approved the merger agreement and the transactions contemplated by the merger agreement. For the factors considered by the DNB board of directors in reaching its decision to approve the merger agreement and the transactions contemplated by the merger agreement, see “The Merger—DNB’s Reasons for the Merger; Recommendation of the DNB Board of Directors.”

Opinion of DNB’s Financial Advisor (Page 39 and 1Annex B)

In connection with the merger, DNB’s financial advisor, PNC FIG Advisory, Inc. (which we refer to as “PNC”), delivered its written opinion, dated June 5, 2019, to DNB’s board of directors to the effect that, as of such date and based upon and subject to various considerations set forth in the opinion, the exchange ratio provided for in the merger was fair to the holders of DNB common stock from a financial point of view.

The full text of PNC’s written opinion, which sets forth, among other things, the assumptions made, procedures followed, factors considered and limitations on the review undertaken, is attached as Annex B to this proxy statement/prospectus. The opinion was rendered for the benefit of DNB’s board of directors (in its capacity as such) in connection with its evaluation of the merger. The opinion is not intended to and does not constitute a recommendation to any DNB shareholder as to how such shareholder should vote or

act with respect to the merger or any matter relating thereto. The opinion does not address the relative merits of the merger as compared to any other transaction or business strategy in which DNB might engage or the merits of the underlying decision by DNB to engage in the merger.

The special meeting will be held on August 1. At the special meeting, Gateway shareholders will be asked to:

1.adopt the merger agreement; and

Each share of Gateway common stock is entitled to one vote. As of the record date of June 25, 2012, there were shares of Gateway common stock entitled to vote at the special meeting.

Required Vote. The affirmative vote of 66 2/3% of the Gateway votes cast is required to adopt the merger agreement and the affirmative vote of a majority of the shares of Gateway common stock present in person or by proxy is required to adjourn the special meeting, in certain circumstances, to solicit additional proxies. A majority of the outstanding Gateway common stock entitled to vote is necessary to constitute a quorum in order to transact business at the special meeting.

Gateway Shareholders Will Receive Cash and Shares of S&T Common Stock in the Merger (page)

You will have the right to receive merger consideration, without interest, for each of your shares of Gateway common stock in the amount of approximately $12.30 per share. You will receive in exchange for each share of Gateway common stock you own immediately prior to completion of the Merger: (i) a cash payment of $3.08 per share; (ii) between 0.3810 and 0.4657 shares of S&T common stock. The precise number of shares will be based upon the average of the high and low sale prices for S&T common stock for the 10 trading day period ending the trading date prior to the closing date.

As an example, based on the average of the high and low sale prices of S&T common stock on The Nasdaq Stock Market for the 10 trading days ending on, 2012 (the most recent practicable date prior to the date of this proxy statement/prospectus), for each share of Gateway common stock held, you would receive $3.08 in cash and shares of S&T common stock, which would have a market value of $.

The following table provides examples of how the value of the merger consideration may change depending on the average high and low share price of S&T common stock. The range of prices set forth in the table has been included for representative purposes only. S&T cannot assure you as to what the market price of the S&T common stock to be issued in the merger will be at or following the time of the exchange. The table assumes that Gateway will not have a right to terminate the merger agreement under the circumstances described under the heading entitled “The Merger Agreement—Termination of the Merger Agreement” on page .

The actual average of the high and low sale prices may be outside the range of the amounts set forth above, and as a result, the actual value of the merger consideration per share of S&T common stock may not be shown in the above table.

You should carefully read “Material United States Federal Income Tax Consequences of the Merger” beginning on page.

The Gateway Stock Options and Warrants Will Be Cancelled in Exchange for a Cash Payment (page)

Upon completion of the merger, each outstanding option and warrant to purchase shares of Gateway common stock, whether or not then exercisable, will be cancelled in exchange for the right to receive a lump sum cash payment equal to the difference between $12.30 and the exercise price of such Gateway stock option or warrant. The lump sum cash payment will be subject to applicable tax withholding.

Your Expected Material United States Federal Income Tax Treatment as a Result of the Merger (page)

We have structured the merger to be treated as a reorganization for United States federal income tax purposes. Each of S&T and Gateway has conditioned the consummation of the merger on its receipt of a legal opinion that this will be the case.

Generally, you will not recognize gain or loss on the exchange of Gateway common stock for S&T common stock in the merger except with respect to the cash you receive, including the cash payment in lieu of a fractional share interest in S&T common stock. With respect to the cash you receive in exchange for your Gateway common stock in the merger, you generally will recognize gain or loss equal to the difference between the amount of cash you receive and your adjusted tax basis in the shares of Gateway common stock you surrender. If you receive cash instead of a fractional share interest in S&T common stock, you will recognize gain or loss on your receipt of that cash.

Exceptions to these conclusions or other considerations may apply. Determining the actual tax consequences of the merger to you can be complicated. Those consequences will depend on your specific situation. For further information, please refer to “Material United States Federal Income Tax Consequences of the Merger” on page .You should also consult your own tax advisor for a full understanding of the merger’s federal income tax and other tax consequences as they apply specifically to you.

Explanation of Use of Non-GAAP Financial Measures

In addition to traditional measures presented in accordance with GAAP, S&T management uses, and this proxy statement/prospectus.

The per share data is not necessarily indicativeprospectus contains or references, certain non-GAAP financial measures identified below. S&T management believes these non-GAAP financial measures provide information useful to investors in understanding S&T’s underlying operational performance and S&T’s business and performance trends as they facilitate comparisons with the performance of other companies in the operating results thatfinancial services industry. Although S&T would have achieved had it completed the merger asmanagement believes that these non-GAAP financial measures enhance investors’ understanding of the beginning of the periods presentedS&T’s business and performance, these non-GAAP financial measures should not be considered as representative of future operations. The pro forma combined information set forth below wasan alternative to GAAP or considered to be more important than financial results determined based upon the issuance of an aggregate of 711,934 sharesin accordance with GAAP, nor are they necessarily comparable with non-GAAP measures which may be presented by S&T.other companies.

RISK FACTORS

In addition to general investment risksCommon tangible book value, common return on average tangible common equity and the ratio of tangible common equity to tangible assets exclude goodwill and other intangible assets in order to show the significance of the tangible elements of S&T’s assets and common equity. Total assets and total average assets are reconciled to total tangible assets and total tangible average assets. Total shareholders' equity and total average shareholders' equity are also reconciled to total tangible common equity and total tangible average common equity. These measures are consistent with industry practice.

TABLE OF CONTENTS

SELECTED CONSOLIDATED HISTORICAL FINANCIAL DATA OF DNB

The following table summarizes selected historical consolidated financial data of DNB for the periods and as of the dates indicated. This information containedhas been derived from DNB’s consolidated financial statements filed with the SEC. Historical financial data as of and for the three months ended March 31, 2019 and March 31, 2018 are unaudited and include, in ormanagement’s opinion, all normal recurring adjustments considered necessary to present fairly the results of operations and financial condition of DNB. You should not assume the results of operations for past periods and for the three months ended March 31, 2019 and March 31, 2018 indicate results for any future period.

You should read this information in conjunction with DNB’s consolidated financial statements and related notes thereto included in DNB’s Annual Report on Form 10-K for the year ended December 31, 2018, and in DNB’s Quarterly Report on Form 10-Q for the three months ended March 31, 2019, which are incorporated by reference into this proxy statement/prospectus, includingprospectus. See “Where You Can Find More Information.”

You should note that the matters underselected historical consolidated financial data includes certain non-GAAP financial measures calculated using non-GAAP amounts. DNB management uses non-GAAP measures to present historical periods comparable to the caption “Cautionary Statement Regarding Forward-Looking Statements,”current period presentation. In addition, DNB management believes the matters discussed under Section 1A, “Risk Factors,” includeduse of non-GAAP measures provides additional clarity when assessing DNB's financial results and use of equity. Disclosures of this type should not be viewed as substitutes for results determined to be in the Annual Reportaccordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other entities.

COMPARATIVE HISTORICAL AND UNAUDITED PRO FORMA PER SHARE DATA
(Unaudited)

Presented below for S&T and DNB is historical, unaudited pro forma combined and pro forma equivalent per share financial data as of and for the year ended December 31, 2011, Gateway shareholders2018 and as of and for the three months ended March 31, 2019. The information presented below should carefully considerbe read together with the following factorshistorical consolidated financial statements of S&T and DNB, including the related notes, filed with the SEC and incorporated by reference into this proxy statement/prospectus. See “Where You Can Find More Information.”

The unaudited pro forma and pro forma equivalent per share information gives effect to the merger as if the merger had been effective on December 31, 2018 or March 31, 2019, in deciding whether to vote for adoptionthe case of the book value data, and as if the merger had been effective as of January 1, 2018, in the case of the earnings per share and the cash dividends data. The unaudited pro forma data combines the historical results of DNB into S&T’s consolidated statement of income. While certain adjustments were made for the estimated impact of fair value adjustments and other acquisition-related activity, they are not indicative of what could have occurred had the acquisition taken place on the dates indicated.

In addition, the unaudited pro forma data includes adjustments that are preliminary and may be revised. The unaudited pro forma data, while helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect the impact of factors that may result as a consequence of the merger or consider any potential impacts of current market conditions or the merger on revenues, expense efficiencies, asset dispositions and share repurchases, among other factors, nor the impact of possible business model changes. As a result, unaudited pro forma data is presented for illustrative purposes only and does not represent an attempt to predict or suggest future results.

TABLE OF CONTENTS

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

The market price of S&T common stock after the merger may be affected by factors different from those currently affecting the shares of S&T.

The businesses of S&T and Gateway differ and, accordingly, the results of operationsSome of the combined company and the market price of the combined company’s shares of common stock may be affected by factors different from those currently affecting the independent results of operations of S&T. For a discussion of the businesses of S&T, see the documentsstatements contained or incorporated by reference in this proxy statement/prospectus and referred to under “Where You Can Find More Information.

Gateway shareholders will have a reduced ownership and voting interest aftercontain forward-looking statements within the merger and will exercise less influence over management.

Gateway’s shareholders currently have the right to vote in the electionmeaning of the boardPrivate Securities Litigation Reform Act of directors of Gateway and on other matters affecting Gateway. When the merger occurs, each Gateway shareholder that receives shares of S&T common stock will become a shareholder of S&T with a percentage ownership of the combined organization that is much smaller than the shareholder’s percentage ownership of Gateway. Upon completion of the merger, the Gateway shareholders will own approximately 2.4% of the outstanding shares of S&T common stock.

Because of this, Gateway’s shareholders will have less influence on the management and policies of S&T than they now have on the management and policies of Gateway.

The merger agreement limits Gateway’s ability1995, including, but not limited to, pursue alternatives to the merger.

The merger agreement contains “no shop” provisions that, subject to specified exceptions, limit Gateway’s ability to discuss, facilitate or commit to competing third-party proposals to acquire all or a significant part of

- 15 -


Gateway. In addition, a termination fee is payable by Gateway under certain circumstances, generally involving the consummation of an alternative transaction. These provisions might discourage a potential competing acquiror that might have an interest in acquiring all or a significant part of Gateway from considering or proposing that acquisition even if it were prepared to pay consideration with a higher per share value than that proposed in the merger, or might result in a potential competing acquiror proposing to pay a lower per share price to acquire Gateway than it might otherwise have proposed to pay.

The merger is subject to the receipt of consents and approvals from governmental and regulatory entities that may impose conditions that could have an adverse effect on S&T.

Before the merger may be completed, various waivers, approvals or consents must be obtained from the Federal Reserve, the FDIC, and the Pennsylvania Department of Banking. These governmental entities may impose conditions on the completion of the merger or require changes to the terms of the merger. Such conditions or changes could have the effect of delaying completion of the merger or imposing additional costs on, or limiting the revenues of, S&T following the merger, any of which might have an adverse effect on S&T following the merger. S&T is not obligated to complete the merger if the regulatory approvals received in connection with the completion of the merger include any condition or restrictions that S&T reasonably determines would have a material adverse effect on S&T or would be unduly burdensome, but S&T could choose to waive this condition.

Gateway’s executive officers and directors have financial interests in the merger that may be different from, or in addition to, the interests of Gateway shareholders.

Gateway’s officers and directors have financial interests in the merger that may be different from, or in addition to, the interests of Gateway shareholders. For example, certain executive officers and employees of Gateway may receive severance payments upon the change of control of Gateway or payments with respect to the cancellation of outstanding equity awards.

Gateway’s board of directors were aware of these interests and took them into account in its decision to approve and adopt the agreement and plan of merger. For information concerning these interests, please see the discussion under the caption “The Merger—Gateway’s Directors and Executive Officers Have Financial Interests in the Merger.

The shares of S&T common stock to be received by Gateway shareholders receiving the stock consideration as a result of the merger will have different rights from the shares of Gateway common stock.

Upon completion of the merger, Gateway shareholders who receive the stock consideration will become S&T shareholders. Their rights as shareholders will be governed by Pennsylvania corporate law and the articles of incorporation and by-laws of S&T. The rights associated with Gateway common stock are different from the rights associated with S&T common stock. See the section of this proxy statement/prospectus titled “Comparison of Shareholders’ Rights” beginning on page for a discussion of the different rights associated with S&T common stock.

If the merger is not consummated by December 31, 2012, either S&T or Gateway may choose not to proceed with the merger.

Either S&T or Gateway may terminate the merger agreement if the merger has not been completed by December 31, 2012, unless the failure of the merger to be completed by such date has resulted from the failure of the party seeking to terminate the merger agreement to perform its obligations.

The fairness opinion obtained by Gateway from its financial advisor will not reflect changes in circumstances subsequent to the date of the merger agreement.

Gateway has obtained a fairness opinion dated as of March 29, 2012 from its financial advisor, KBW. Gateway has not obtained and will not obtain an updated opinion as of the date of this proxy statement/prospectus from KBW. Changes in the operations and prospects of S&T or Gateway, general market

- 16 -


and economic conditions and other factors that may be beyond the control of S&T and Gateway, and on which the fairness opinion was based, may alter the value of S&T or Gateway or the price of shares of S&T common stock or Gateway common stock by the time the merger is completed. The opinion does not speak to the time the merger will be completed or to any other date other than the date of such opinion. As a result, the opinion will not address the fairness of the merger consideration, from a financial point of view, at the time the merger is completed. For a description of the opinion that Gateway received from KBW, please see “The Merger—Opinion of Gateway’s Financial Advisor” beginning on page of this proxy statement/prospectus.

We may fail to realize all of the anticipated benefits of the merger.

The success of the merger will depend, in part, on our ability to realize the anticipated benefits and cost savings from combining the businesses of S&T and Gateway. However, to realize these anticipated benefits and cost savings, we must successfully combine the businesses of S&T and Gateway. If we are not able to achieve these objectives, the anticipated benefits and cost savings of the merger may not be realized fully or at all, or may take longer to realize than expected.

S&T and Gateway have operated and, until the completion of the merger, will continue to operate, independently. It is possible that the integration process could result in the loss of key employees, the disruption of each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect our ability to maintain relationships with clients, customers, depositors and employees or to achieve the anticipated benefits of the merger. Integration efforts between the two companies will also divert management attention and resources. These integration matters could have an adverse effect on S&T and/or Gateway during the transition period.

Another expected benefit from the merger is an expected increase in the revenues of the combined company from anticipated sales of S&T’s wide variety of financial products, and from increased lending out of S&T’s substantially larger capital base, to Gateway’s existing customers and to new customers in Gateway’s market area who may be attracted by the combined company’s enhanced offerings. An inability to successfully market S&T’s products to Gateway’s customer base could cause the earnings of the combined company to be less than anticipated.

If the merger is not completed, S&T and Gateway will have incurred substantial expenses without realizing the expected benefits of the merger.

S&T and Gateway have incurred substantial expenses in connection with the merger described in this proxy statement/prospectus. The completion of the merger depends on the satisfaction of specified conditions and the receipt of regulatory approvals. If the merger is not completed, these expenses would have to be recognized currently and not capitalized and S&T and Gateway would not have realized the expected benefits of the merger.

Gateway will be subject to business uncertainties and contractual restrictions while the merger is pending.

Uncertainty about the effect of the merger on employees and customers may have an adverse effect on Gateway and consequently on S&T. These uncertainties may impair Gateway’s ability to attract, retain and motivate key personnel until the merger is consummated, and could cause customers and others that deal with Gateway to seek to change existing business relationships with Gateway. Retention of certain employees may be challenging during the pendency of the merger, as certain employees may experience uncertainty about their future roles with S&T. If key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with S&T, S&T’s business following the merger could be harmed. In addition, the merger agreement restricts Gateway from making certain acquisitions and taking other specified actions until the merger occurs without the consent of S&T. These restrictions may prevent Gateway from pursuing attractive business opportunities that may arise prior to the completion of the merger. Please see the

section entitled “The Merger Agreement—Covenants and Agreements” beginning on page of this proxy statement/prospectus for a description of the restrictive covenants to which Gateway is subject under the merger agreement.

Future governmental regulation and legislation, including the Dodd-Frank Act, could limit S&T’s future growth.

S&T and its subsidiaries are subject to extensive state and federal regulation, supervision and legislation that govern almost all aspects of the operations of S&T. These laws may change from time to time and are primarily intended for the protection of consumers, depositors and the deposit insurance fund. Any changes to these laws may negatively affect S&T’s ability to expand its services and to increase the value of its business. Additionally, a number of provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, remain to be implemented through the rulemaking process at various regulatory agencies. Certain aspects of the new law, including, without limitation, the higher cost of deposit insurance and the costs of compliance with disclosure and reporting requirements that may be issued by the Bureau of Consumer Financial Protection, could have a significant adverse impact on the combined company’s business, financial condition and results of operations. Compliance with the Dodd-Frank Act may require us to make changes to our business and operations and will likely result in additional costs and a diversion of management’s time from other business activities, any of which may adversely impact our results of operations, liquidity or financial condition. While we cannot predict what effect any presently contemplated or future changes in the laws or regulations or their interpretations would have on S&T, these changes could be materially adverse to S&T’s shareholders.

RISK FACTORS

In addition to the other information contained in or incorporated by reference into this proxy statement/prospectus, including the matters addressed under the caption “Cautionary Statement Regarding Forward-Looking Statements,” you should consider the following risk factors carefully in deciding whether to vote to approve the merger agreement and the transactions contemplated by the merger agreement. Additional risks and uncertainties not presently known to S&T or DNB, if they materialize, also may adversely affect the merger and S&T as the surviving corporation in the merger.

In addition, S&T’s and DNB’s respective businesses are subject to numerous risks and uncertainties, including the risks and uncertainties described in this section and their respective Annual Reports on Form 10-K for the year ended December 31, 2018 and subsequent Quarterly Reports on Form 10-Q, each of which are incorporated by reference into this proxy statement/prospectus. See “Where You Can Find More Information.”

Because the market price of S&T common stock will fluctuate, DNB shareholders cannot be certain of the market value of the merger consideration they will receive.

Upon completion of the merger, each share of DNB common stock will be converted into 1.22 shares of S&T common stock. The market value of the merger consideration may vary from the closing price of S&T common stock on the date the parties announced the merger, on the date that this proxy statement/prospectus is mailed to DNB shareholders, on the date of the special meeting of the DNB shareholders and on the date the merger is completed. Any change in the market price of S&T common stock prior to the completion of the merger will affect the market value of the merger consideration that DNB shareholders will receive upon completion of the merger, and there will be no adjustment to the merger consideration for changes in the market price of either shares of S&T common stock or shares of DNB common stock.

Stock price changes may result from a variety of factors that are beyond the control of S&T and DNB, including, but not limited to, general market and economic conditions, changes in the respective businesses of S&T and DNB, operations and prospects and regulatory considerations. Therefore, at the time of the DNB special meeting, holders of DNB common stock will not know the precise market value of the consideration they will receive at the effective time of the merger. Shareholders should obtain current market quotations for shares of S&T common stock and for shares of DNB common stock.

The market price of S&T common stock after the merger may be affected by factors different from those affecting the shares of DNB or S&T currently.

Upon completion of the merger, holders of DNB common stock will become holders of S&T common stock. S&T’s business differs in important respects from that of DNB, and, accordingly, the results of operations of the combined company and the market price of S&T common stock after the completion of the merger may be affected by factors different from those currently affecting the independent results of operations of each of S&T and DNB.

Approvals required to complete the merger may not be received, may take longer than expected or may impose conditions that are not presently anticipated or that could have an adverse effect on the combined company following the merger.

Before the merger and the bank merger may be completed, S&T and DNB must obtain approvals from the Federal Reserve Board, the FDIC and the Pennsylvania Department of Banking and Securities, as well as from the shareholders of DNB. Other approvals, waivers or consents from regulators may also be required. If these approvals are not obtained or waived, to the extent requiredpermitted by applicable law or regulation, stock exchange rules, the merger may not occur or may be delayed. Additionally, regulators may impose conditions on the completion of the merger or require changes to the terms of the merger. Such conditions or changes could have the effect of delaying or preventing completion of the merger or imposing additional costs on or limiting the revenues of the combined company following the merger, any of which might have an adverse effect on the combined company following the merger. See “The Merger—Regulatory Approvals Required for the Merger.”

Combining the two companies may be more difficult, costly or time consuming than expected and the anticipated benefits and cost savings of the merger may not be realized.

S&T and Gateway undertake no obligationDNB have operated and, until the completion of the merger, will continue to updateoperate, independently. The success of the merger, including anticipated benefits and cost savings, will depend, in part, on S&T’s ability

22

TABLE OF CONTENTS

to successfully combine the businesses of S&T and DNB. To realize these forward-looking statementsanticipated benefits and cost savings, after the completion of the merger, S&T expects to integrate DNB’s business into its own.

It is possible that the integration process could result in the loss of key employees, the disruption of each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect the combined company’s ability to maintain relationships with clients, customers, depositors and employees or to achieve the anticipated benefits and cost savings of the merger. The loss of key employees could adversely affect S&T’s ability to successfully conduct its business in the markets in which DNB now operates, which could have an adverse effect on S&T’s financial results and the value of its common stock. If S&T experiences difficulties with the integration process, the anticipated benefits of the merger may not be realized fully or at all, or may take longer to realize than expected.

As with any merger of financial institutions, there also may be business disruptions that cause S&T and/or DNB to lose customers or cause customers to remove their accounts from S&T and/or DNB and move their business to competing financial institutions. Integration efforts between the two companies will also divert management attention and resources. These integration matters could have an adverse effect on each of S&T and DNB during this transition period and for an undetermined period after completion of the merger on the combined company. In addition, the actual cost savings of the merger could be less than anticipated.

The fairness opinion received by the DNB board of directors from DNB’s financial advisor prior to the signing of the merger agreement does not reflect events orchanges in circumstances aftersince the date of such opinion.

The DNB board of directors received a fairness opinion dated June 5, 2019 from PNC, and such opinion has not been updated as of the date of this proxy statement/prospectus and will not be updated at the time of the completion of the merger. Changes in the operations and prospects of S&T or DNB, general market and economic conditions and other factors that may be beyond the control of S&T and DNB may alter the value of S&T or DNB or the prices of shares of S&T common stock or DNB common stock by the time the merger is completed.

The fairness opinion does not address the fairness of the merger consideration, from a financial point of view, at the time the merger is completed or as of any other date than the date of the opinion. The fairness opinion that the DNB board of directors received from PNC is attached as Annex Bto this proxy statement/prospectus.

For a description of the opinion, see “The Merger—Opinion of DNB’s Financial Advisor.” For a description of the other factors considered by the DNB board of directors in determining to approve the merger agreement and the transactions contemplated by the merger agreement, see “The Merger—DNB’s Reasons for the Merger; Recommendation of the DNB Board of Directors.”

Certain of DNB’s directors and executive officers have interests in the merger that may differ from the interests of DNB’s shareholders, including, if the merger is completed, the receipt of financial and other benefits.

DNB shareholders should be aware that some of DNB’s directors and executive officers have interests in the merger and have arrangements that are different from, or in addition to, those of DNB shareholders generally. These interests and arrangements may create potential conflicts of interest. The DNB board of directors was aware of these interests and considered these interests, among other matters, when making its decision to approve the merger agreement and the transactions contemplated by the merger agreement, and in recommending that DNB’s shareholders vote in favor of approving the merger agreement and the transactions contemplated by the merger agreement.

These interests include:

at the effective time, each restricted stock award in respect of DNB common stock will vest in full and the restrictions thereon will lapse, and will be converted into a right to receive the merger consideration (less applicable tax withholdings) with respect to each share of DNB common stock subject to the award; and
each of the named executive officers of DNB is party to various agreements with DNB and its affiliates that entitle such officers to certain payments and benefits in the event that such named executive officer experiences a qualifying termination of employment following a change in control of DNB.

23

TABLE OF CONTENTS

For a more complete description of these interests, see “The Merger—Interests of DNB’s Directors and Executive Officers in the Merger” and “The Merger Agreement—Treatment of DNB Equity Awards.”

The directors and certain executive officers of DNB have each entered into voting agreements with S&T, solely in his or her capacity as a shareholder of DNB, pursuant to which he or she has agreed, among other things, to vote in favor of the DNB merger proposal and the other proposals presented at the DNB special meeting and against any alternative acquisition proposal. For more information regarding the voting agreements, see “The Merger Agreement—Voting Agreements.” As of the record date, DNB shareholders who are parties to the voting agreements beneficially owned and were entitled to vote approximately [         ] shares of DNB common stock representing approximately [         ]% of the shares of DNB common stock outstanding on that date.

Termination of the merger agreement could negatively impact DNB or S&T.

There may be various negative consequences if the merger agreement is terminated. For example, DNB’s or S&T’s businesses may have been impacted adversely by the failure to pursue other beneficial opportunities due to the focus of management on the merger, without realizing any of the anticipated benefits of completing the merger. Additionally, if the merger agreement is terminated, the market price of DNB’s or S&T’s common stock could decline to the extent that the current market prices reflect a market assumption that the occurrencemerger will be completed. If the merger agreement is terminated under certain circumstances, DNB may be required to pay to S&T a termination fee of unanticipated events.

$8 million.

Failure to complete the merger could negatively impact the stock price and the future business and financial results of S&T or DNB.

- 19 -If the merger is not completed for any reason, including as a result of DNB shareholders declining to approve the merger agreement and the transactions contemplated by the merger agreement, the ongoing business of S&T or DNB may be adversely affected and, without realizing any of the benefits of having completed the merger, S&T or DNB would be subject to a number of risks, including the following:

S&T or DNB may experience negative reactions from the financial markets, including negative impacts on its stock price;
S&T or DNB may experience negative reactions from its customers, vendors and employees;
The merger agreement places certain restrictions on the conduct of S&T’s and DNB’s respective businesses prior to completion of the merger. Such restrictions, the waiver of which is subject to the consent of the other party (not to be unreasonably withheld or delayed), may prevent each company from taking certain specified actions during the pendency of the merger (see “The Merger Agreement—Covenants and Agreements—Conduct of Businesses Prior to the Completion of the Merger”); and
Matters relating to the merger (including integration planning) will require substantial commitments of time and resources by S&T and DNB management, which would otherwise have been devoted to other opportunities that may have been beneficial to S&T and DNB as independent companies.

DNB will be subject to business uncertainties and contractual restrictions while the merger is pending.


Uncertainty about the effect of the merger on employees and customers may have an adverse effect on DNB. These uncertainties may impair DNB’s ability to attract, retain and motivate key personnel until the merger is completed and could cause customers and others that deal with DNB to seek to change existing business relationships with DNB. Retention of certain employees by DNB may be challenging while the merger is pending, as certain employees may experience uncertainty about their future roles with DNB or S&T. If key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with DNB or S&T, DNB’s business or, following the merger, the combined business could be harmed. In addition, subject to certain exceptions, DNB has agreed to operate its business in the ordinary course prior to closing. See “The Merger Agreement—Covenants and Agreements—Conduct of Businesses Prior to the Completion of the Merger” for a description of the restrictive covenants applicable to DNB.

TABLE OF CONTENTS

If the merger is not completed, S&T and DNB will have incurred substantial expenses without realizing the expected benefits of the merger.

Each of S&T and DNB has incurred and will incur substantial expenses in connection with the negotiation and completion of the transactions contemplated by the merger agreement, as well as the costs and expenses of filing, printing and mailing this proxy statement/prospectus and all filing and other fees paid to the SEC and fees to other regulators in connection with the merger. If the merger is not completed, S&T and DNB would have to recognize these and other expenses without realizing the expected benefits of the merger.

The merger agreement limits DNB’s ability to pursue an alternative acquisition proposal and requires it to pay a termination fee of $8 million under certain circumstances.

The merger agreement prohibits DNB from initiating, soliciting, knowingly encouraging or knowingly facilitating certain alternative acquisition proposals with any third party, subject to exceptions set forth in the merger agreement. See “The Merger Agreement—Agreement Not to Solicit Other Offers.” The merger agreement also provides that DNB must pay to S&T a termination fee in the amount of $8 million in the event that the merger agreement is terminated for certain reasons, including circumstances involving a change in company recommendation by the DNB board of directors. These provisions might discourage a potential competing acquirer that might have an interest in acquiring all or a significant part of DNB from considering or proposing such an acquisition. See “The Merger Agreement—Termination Fee.”

The shares of S&T common stock to be received by DNB shareholders as a result of the merger will have different rights from the shares of DNB common stock.

Upon completion of the merger, DNB shareholders will become S&T shareholders, and their rights as shareholders will be governed by S&T’s articles of incorporation and bylaws, each as amended to date, and will continue to be governed by Pennsylvania law. The rights associated with DNB common stock are different from the rights associated with S&T common stock. Please see “Comparison of Shareholders’ Rights” beginning on page 76 for a discussion of the different rights associated with S&T common stock.

DNB’s shareholders will have a reduced ownership and voting interest after the merger and will exercise less influence over management.

Currently, DNB’s shareholders have the right to vote in the election of the DNB board of directors and the power to approve or reject any matters requiring shareholder approval under Pennsylvania law and DNB’s articles of incorporation and bylaws, each as amended to date. Upon the completion of the merger, each DNB shareholder will become a shareholder of S&T, with a percentage ownership of S&T that is smaller than the shareholder’s current percentage ownership of DNB.

After the merger, DNB shareholders in the aggregate are expected to become owners of approximately [         ]% of the outstanding shares of S&T common stock (without giving effect to any shares of S&T common stock held by DNB shareholders prior to the merger). Even if all former DNB shareholders voted together on all matters presented from time to time to S&T’s shareholders, the former DNB shareholders would exercise significantly less influence over S&T after the merger relative to their influence over DNB prior to the merger, and thus would have a less significant impact on the approval or rejection of future proposals submitted to a shareholder vote.

Votes “FOR” and “AGAINST” and “ABSTAIN” will all be counted as present for purposes of determining whether a quorum exists. Broker non-votes are counted as present for purposes of determining whether a quorum exists only if instructions have been provided by the beneficial owner to the applicable bank, brokerage firm or nominee with respect to at least one proposal.

TABLE OF CONTENTS

Shares Held in “Street Name”; Broker Non-votes

A bank, broker or other nominee holding shares in “street name” for a beneficial owner has discretion (but is not required) to vote the client’s shares with respect to “routine” matters if the client does not provide voting instructions. The bank, broker or other nominee, however, is not permitted to vote the client’s shares with respect to “non-routine” matters without voting instructions from the beneficial owner. A “broker non-vote” occurs when your bank, broker or other nominee submits a proxy for your shares but does not vote on a particular proposal because the bank, broker or other nominee does not have discretionary voting power for that item and has not received instructions from you.

We believe that the DNB merger proposal, the DNB adjournment proposal and the DNB compensation proposal are “non-routine” proposals, and your bank, broker or other nominee can vote your shares of DNB common stock only with your specific voting instructions. Broker non-votes, if any, will be counted for purposes of determining a quorum (but only if instructions have been provided by the beneficial owner to the applicable bank, brokerage firm or nominee with respect to at least one proposal), but will not be treated as votes cast. Accordingly, because approval of the DNB merger proposal requires the affirmative vote of at least a majority of the outstanding shares of DNB common stock entitled to vote on the proposal, a broker non-vote will have the effect of a vote “AGAINST” the DNB merger proposal. Broker non-votes will have no effect on the outcome of the DNB merger proposal, the DNB adjournment proposal or the DNB compensation proposal.

Revocability of Proxies and Changes to a DNB Shareholder’s Vote

Any shareholder entitled to vote in person at the DNB special meeting may vote in person regardless of whether a proxy has been previously given, and such vote will revoke any previous proxy but the mere presence (without notifying Gateway’s Secretary) of a shareholderattendance at the DNB special meeting by itself will not constitute revocation ofautomatically revoke your proxy or change your vote– you must cast a previously given proxy.new vote at the DNB special meeting in order to revoke your prior vote.

DNB is asking its shareholders to approve the merger agreement and the transactions contemplated thereby, including the merger. Holders of DNB common stock should read this proxy statement/prospectus carefully and in its entirety for more detailed information concerning the merger agreement and the merger. A copy of the merger agreement is attached to this proxy statement/prospectus as Annex A.

The DNB board of directors has determined that the merger agreement and the merger are advisable and in the best interests of DNB and its shareholders and has unanimously approved the merger agreement and the transactions contemplated by the merger agreement. See “The Merger—DNB’s Reasons for the Merger; Recommendation of the DNB Board of Directors” for a more detailed discussion of the recommendation of the DNB board of directors.

The DNB board of directors unanimously recommends a vote “FOR” the DNB merger proposal.

PROPOSAL NO. 2: DNB ADJOURNMENT PROPOSAL

The DNB special meeting may be adjourned to another time or place, if necessary or appropriate, to permit, among other things, further solicitation of proxies if necessary to obtain additional votes in favor of the DNB merger proposal.

If, at the DNB special meeting, the number of shares of DNB common stock present or represented and voting in favor of the DNB merger proposal is insufficient to approve such proposal, DNB intends to move to adjourn the DNB special meeting in order to solicit additional proxies for the approval of the DNB merger proposal.

In this proposal, DNB is asking its shareholders to authorize the holder of any proxy solicited by the DNB board of directors on a discretionary basis to vote in favor of adjourning the DNB special meeting to another time and place for the purpose of soliciting additional proxies, including the solicitation of proxies from DNB shareholders who have previously voted.

The DNB board of directors unanimously recommends a vote “FOR” the DNB adjournment proposal.

PROPOSAL NO. 3: DNB COMPENSATION PROPOSAL

In accordance with Section 14A of the Securities Exchange Act of 1934, as amended (which we refer to as the “Exchange Act”), the DNB board of directors is providing shareholders with the opportunity to cast a non-binding advisory vote on the compensation payable to the named executive officers of DNB in connection with the merger. This proposal gives DNB shareholders the opportunity to express their views on the compensation that DNB’s named executive officers will be entitled to receive in connection with the proposed merger. This compensation is summarized in the table in the section titled “The Merger—Interests of DNB’s Directors and Executive Officers in the Merger,” including the footnotes to the table.

As required by Section 14A of the Exchange Act, DNB is asking its shareholders to vote on the adoption of the following resolution:

RESOLVED, that the compensation that may be paid or become payable to DNB’s named executive officers in connection with the merger, as disclosed in the section titled “The Merger—Interests of DNB’s Directors and Executive Officers in the Merger,” including the table, associated footnotes and narrative discussion related thereto, is hereby APPROVED.

The vote on the DNB compensation proposal is a vote separate and apart from the vote to approve the merger agreement and the transactions contemplated by the merger agreement. You may vote for the DNB compensation proposal and against the DNB merger proposal, and vice versa. Because the vote on the DNB compensation proposal is advisory only, it will not be binding on either DNB or S&T. Accordingly, because DNB or S&T, as applicable, is contractually obligated to pay the compensation, if the merger is completed, the compensation will be payable, subject to the conditions applicable thereto, regardless of the outcome of the advisory vote.

The DNB board of directors unanimously recommends a vote “FOR” the DNB compensation proposal.

The GatewayDNB board of directors has periodically reviewedunanimously approved the merger agreement and discussed Gateway’s futurethe transactions contemplated by the merger agreement.

For a discussion of the treatment of awards outstanding under DNB’s equity plans outstanding as of the effective time, see “The Merger Agreement—Treatment of DNB Equity Awards.”

DNB shareholders are being asked to approve the merger agreement and the transactions contemplated by the merger agreement. See “The Merger Agreement” for additional, detailed information regarding the legal documents that govern the merger, including information about the conditions to the completion of the merger and the provisions for terminating or amending the merger agreement.

Background of the Merger

As part of its ongoing consideration and evaluation of DNB’s long-term prospects and strategies, the DNB board of directors and management regularly review and assess DNB’s business strategies, opportunities and challenges in light of developments in DNB’s business, in the industries in which it competes, in the economy generally and in the financial markets, with the goal of enhancing value for its shareholders.

The DNB board of directors and members of DNB’s senior management have regularly met with representatives of certain investment banking firms experienced in the banking industry, including representatives of Ambassador Financial Group, Inc. (which was subsequently acquired by PNC Bank, National Association and has considered variousbeen renamed PNC FIG Advisory, Inc. and which we refer to as “PNC”) to discuss market conditions, industry trends, DNB’s performance, developments in mergers and acquisitions and potential strategic alternatives. The expected increaseopportunities. In addition, from time to time, DNB has had general discussions with other financial institutions regarding the possibility of regulationa potential future strategic transaction.

In the early part of 2019, the DNB board of directors and oversight on community banks as a resultmanagement continued their discussions regarding DNB’s business strategies, opportunities and challenges, and began discussing exploring possibilities for enhancing value for shareholders by considering approaches to gain an understanding of the Dodd-Frank Act passedpotential level of interest of third parties in 2010;acquiring DNB. At this time, the difficulty for smaller community banks to access the capital markets to obtain equity capital to meet increasing regulatory capital requirements and to support growth; and the adverse effectsDNB board of a lengthy economic slowdown on Gateway and its customers are all factors which may impact the future financial performance of Gateway. In considering the future direction of Gateway the boarddirectors and management also took advice from financial advisors, investment banking firms,began regularly consulting with legal counsel at Stradley Ronon Stevens & Young, LLP (which we refer to as “Stradley”) regarding DNB’s process for considering various alternatives for enhancing shareholder value. On February 27, 2019, at a regularly scheduled meeting of the DNB board of directors that was attended by representatives of Stradley, members of the board discussed the future and other professionals in the financial industry on the effectsstrategic plans of these factors on Gateway’s ability to increase shareholder valueDNB with DNB’s senior management and maintain a stable financial position in the future. In assessing Gateway’smanagement’s views regarding DNB’s prospects as an independent community bank and the anticipated challenges to maintaining DNB’s competitive position and enhancing shareholder value. Based on those discussions, the DNB board and management also considered the lack of liquidity of Gateway’s privately held common stock.

At the request of a senior officer of another financial institution who was interested in a business combination with Gateway, Gateway’s President and Chief Executive Officer attended a meeting with this senior officer on July 12, 2011. In light of the factors described, Gateway’s President and Chief Executive Officer met again on July 27, 2011 and on August 9, 2011 with representatives of this financial institutiondirectors determined it advisable to discuss the potential for a business combination. On September 8, 2011, Gateway contacted theretain an investment banking firm to serve as DNB’s financial advisor to provide additional assistance to the board as it considered these matters. In connection with its determination, the board authorized a sub-group of its members, consisting of James H. Thornton, the board’s Chairman, Gerald F. Griesser, James R. Biery and John F. McGill to meet with the

33

TABLE OF CONTENTS

investment banks to discuss current market conditions and developments in mergers and acquisitions, as well as a process for exploring the potential interest of third parties in acquiring DNB. Following those meetings, and upon the recommendation of the sub-group, the DNB board of directors approved the engagement of PNC to serve as DNB’s financial advisor.

The DNB board of directors authorized PNC to contact an approved group of financial institutions to solicit their potential interest in pursuing a strategic transaction and discuss their views regarding DNB’s valuation if they were interested in pursuing an acquisition of DNB. The financial institutions contacted by PNC were selected based on a variety of factors, including their expected level of potential interest in pursuing a strategic transaction with DNB, their apparent ability to complete a strategic transaction with DNB, and their perceived strategic fit. In mid-March 2019, with DNB’s approval, PNC contacted 19 financial institutions on a confidential basis. Of the 19 financial institutions contacted, 12 indicated sufficient interest that they were provided a form of non-disclosure agreement that, if executed and returned, would allow them to receive certain nonpublic information regarding DNB. Eight of those financial institutions, including S&T, expressed interest in receiving nonpublic information about DNB. Between March 19, 2019 and April 2, 2019, DNB entered into confidentiality agreements containing customary provisions with each of the eight financial institutions, including with S&T on March 19, 2019. The confidentiality agreements included a customary standstill provision that provided that such provision would terminate if DNB entered into an agreement providing for the sale or change in control of DNB. Thereafter, DNB provided limited high-level diligence information to each of the eight parties that entered into confidentiality agreements.

During the second half of April, four of the parties that entered into confidentiality agreements with DNB delivered to PNC preliminary indications of interest relating to a transaction with DNB. On April 22, 2019, S&T delivered to PNC a preliminary nonbinding proposal to acquire DNB at a price range of $46 and $48 per share of DNB common stock, with the consideration to be paid in S&T common stock using a fixed exchange ratio. S&T also proposed to appoint one member of the DNB board of directors to the S&T board of directors upon consummation of the proposed transaction. In connection with such indication of interest, S&T requested a period of exclusivity of 60 days in order to discuss and finalize a transaction.

On April 24, 2019, the DNB board of directors met at a regularly scheduled meeting. At this meeting, PNC provided the DNB board of directors with an update on the process, including a review of the four preliminary non-binding proposals that had been received. The DNB board of directors discussed the key features of the proposals, including the proposed purchase price, the structure of the merger consideration, each party’s perceived interest in negotiating and entering into a transaction and each party’s likely ability to obtain required transaction approvals from its respective banking regulators in a timely manner, as well as certain background information regarding each of the parties. Stradley provided an overview of legal and fiduciary matters. The DNB board of directors observed that S&T’s proposal represented the highest indicative price level received from any party, noting that the other proposals fell within a range of $41 to $43.50 per share of DNB common stock compared with the $46 to $48 range proposed by S&T, and discussed its belief that S&T’s proposal would provide significantly more value to DNB shareholders as compared to the proposals from the three other potential counterparties and DNB’s standalone alternatives. The DNB board of directors noted the 60-day exclusivity period requested by S&T in its proposal and expressed its belief that, under the circumstances, a 45-day exclusivity period would be appropriate and acceptable. The DNB board of directors then discussed with PNC the possibility that any of the three other potential counterparties would increase their proposed price ranges to be competitive with, or exceed, the price range indicated in the S&T proposal. The DNB board of directors concluded that, based on PNC’s discussions with the three other potential counterparties, it was highly unlikely that any of them would increase their proposed price ranges to be competitive with, or exceed, the price range indicated in the S&T proposal.

The DNB board of directors then approved a motion to authorize management to execute and return the S&T proposal, subject to S&T’s agreement to reduce the exclusivity period from 60 days to 45 days. The DNB board of directors also directed that a request be made to S&T to agree to appoint a second member of the DNB board of directors to the S&T board of directors upon consummation of the proposed transaction. In subsequent discussions between representatives of DNB and S&T, and prior to DNB’s delivery to S&T of a countersigned acceptance of S&T’s proposal, S&T indicated that it would be prepared to discuss and finalize at a future date the exchange ratio within the $46 to $48 price range it had proposed, based on discussions between the

companies and its due diligence findings. S&T also indicated it would propose appointing two members of the DNB board of directors to the S&T board of directors upon consummation of the proposed transaction and agreed to a reduction in the exclusivity period from 60 days to 45 days.

On May 1, 2019, S&T and its representatives, including its financial advisor, Keefe, Bruyette & Woods, Inc. (“KBW”(which we refer to as “KBW”) and legal adviser, Wachtell, Lipton, Rosen & Katz (which we refer to assist Gateway in evaluating whether or not it would be in Gateway’s best interestas “Wachtell, Lipton”) obtained access to remain independent or to explore other strategic alternatives such as a potential merger or sale. KBW and Gateway subsequently signed a Non-Disclosure Agreement dated as of September 14, 2011.

At Gateway’s Executive Committee meeting on October 20, 2011, KBW made a presentation tovirtual data room containing due diligence materials concerning DNB. Over the Committee setting forth the current industry environment, the current merger and acquisition environment, financial projections for Gateway as a standalone institution and a combination analysis for a merger with the institution with which Gateway was engaged in discussions, and combinations with other potential partners. At Gateway’s Executive Committee meeting on November 17, 2011, management was authorized to enter into an agreement with KBW to explore a potential merger or sale with any number of potential partners, in addition to the institution with whom Gateway was currently negotiating, and an engagement letter was entered into between Gateway and KBW dated November 28, 2011.

During the remaindercourse of the year, KBWfollowing month, S&T and Gateway prepared a confidential information memorandum for possible distribution to 14 institutions determined by KBW and Gateway to have potential interest in an acquisition of Gateway. Confidentiality agreements were executed by nine of these institutions and they each received a copy of the confidential information memorandum regarding Gateway.

Five financial institutions, includingits representatives continued S&T, submitted non-binding indications of interest by the preliminary bid deadline of January 20, 2012. Gateway’s Executive Committee held a meeting on January 26, 2012 where KBW reviewed in detail these preliminary indications of interest. Of the five preliminary indications of interest, two were all cash offers, one for $10.00 per share and one for $10.50 to $10.75 per share (with a willingness to offer up to 15% stock), two were mixed stock-cash offers with the first at $10.86 per share with a fixed exchange ratio and stock-cash consideration of 40% stock and 60% cash, and the second at $11.00 per share with a fixed exchange ratio and stock-cash consideration of 70% stock and 30% cash, and one offer of all stock (with a willingness to offer up to 50% cash) at $10.00 to $10.80 per share with a fixed exchange ratio. All of the indications of interest were subject to the completion of&T’s due diligence on Gateway. After conferringinvestigation of DNB, and DNB continued to make due diligence materials available to S&T and its representatives.

On May 9, 2019, senior management of DNB met in person with KBW, the Executive Committee directed KBW to invite threesenior management of these institutions, including S&T to conductdiscuss the potential transaction.

On May 15 and 16, 2019, S&T’s management and its representatives attended in-person due diligence on Gatewaydiscussions with DNB’s management and to submit a second and final indication of interest. As part of the due diligence process,

- 23 -


Gateway documents were made available on an online data site and from February 8, 2012 to February 16, 2012 these three institutions, including S&T, conducted further independent on site due diligence of Gateway at Gateway’s headquarters. On February 16, 2012 KBW transmitted a letter to each of the remaining three institutions inviting them to submit final non-binding indications of interest by February 27, 2012.

At a meeting of Gateway’s Executive Committee on March 2, 2012, the bids of the three final non-binding indications of interest were discussed and were analyzed in detail with the assistance of KBW. The first offer was all cash at $11.45 per share. The second offer was initially a mixed stock-cash offer for $11.50 per share with a fixed exchange ratio and stock-cash consideration of 70% stock and 30% cash. However, on March 1, this offer was orally increased to $12.00 per share with all the other terms remaining the same. The third offer was all stock at $12.00 per share with a fixed exchange ratio (with a willingness to offer up to 25% cash). At the conclusion of this Executive Committee meeting KBW was directed to request that the two $12.00 per share bidders, including S&T, differentiate their respective offers by submitting a best and final non-binding indication of interest by March 7, 2012.its representatives.

On March 9, 2012 Gateway held a meeting of its Executive Committee as well as a meeting of its Board of Directors to compare the final two offers. KBW and Gateway’s legal counsel participated in the meeting.

The first of the final offers was for $12.00 per share with a fixed exchange ratio and stock-cash consideration of 60% stock and 40% cash and the second offer, that of S&T, was for $12.30 per share with a floating exchange ratio at 100% stock and a willingness to offer up to 25% in cash. Both offers had collars with regard to movement in the acquiror’s stock price in excess of 10%. The first collar proposal allowed for a one-time adjustment to the fixed exchange ratio if the 10% collars were breached. The second collar proposal, that of S&T, allowed for a one-time adjustment to cause the floating exchange ratio within the collars to become a fixed exchange ratio if the 10% collars were breached. All other aspects of the two offers were substantially similar. The Executive Committee directed management to proceed with the S&T offer, assuming a stock-cash consideration of 75% stock and 25% cash, and so informed the Gateway Board of Directors, which approved of proceeding in this fashion pending reverse due diligence on S&T and pending the negotiation of a satisfactory merger agreement. On March 9, 2012 Gateway notified S&T that it wished to proceed with exclusive negotiations for an acquisition transaction with S&T and requested that it be able to conduct reverse due diligence on S&T and asked S&T to submitMay 17, 2019, Wachtell, Lipton, distributed a draft merger agreement for Gateway’s review.

AOn May 22, 2019, at a regularly scheduled meeting of the DNB board of directors, DNB senior management discussed with the board the status of negotiations with S&T, the status of S&T’s due diligence and DNB’s plans to proceed with reverse due diligence. Representatives of Stradley discussed with the board key terms of the draft of merger agreement and form of voting agreements, including terms that were the subject of ongoing negotiations between Stradley and Wachtell, Lipton. During the negotiation process, members of the DNB board of directors were regularly apprised of progress in the negotiations by Mr. Thornton, the board’s Chairman.

Over the course of the following weeks, DNB continued its reverse due diligence investigation of S&T, and S&T continued to make due diligence information available to DNB and its representatives.

During late May and continuing into early June 2019, representatives of S&T and DNB regularly met and continued to discuss the final terms of the proposed transaction, including the exchange ratio, which the parties agreed would be established within the range of S&T’s indication of interest. During these discussions, S&T proposed an exchange ratio of 1.20 shares of S&T common stock to be issued in exchange for each share of DNB common stock in the merger. Representatives of DNB proposed an exchange ratio of 1.24.

On the morning of June 1, 2019, the sub-group of DNB’s board of directors (which now included an additional director, G. Daniel O'Donnell) met with certain members of DNB’s senior management and PNC in attendance, to discuss certain open issues regarding the merger agreement, including the proposed exchange ratio and protective provisions that would give DNB a right to terminate the merger agreement in the event of a significant decline in S&T’s stock price after the signing of the merger agreement. Following the discussion, PNC was instructed to again discuss with S&T’s representatives the exchange ratio of 1.24 previously proposed by DNB and also discuss the inclusion of such termination rights in the merger agreement.

On the afternoon of June 3, 2019, a special meeting of Gateway’sthe S&T board of directors was held. At this meeting, management gave a detailed review of the status of discussions, including with respect to the exchange ratio, with DNB and its due diligence findings.

Thereafter, representatives of DNB and S&T tentatively agreed to an exchange ratio of 1.22, subject to the approval of each of their respective boards of directors.

Gateway’s Reasons for the Merger

Gateway’s board of directors carefully considered the process by which potential acquirers were identified and multiple bids were received and evaluated, the terms and conditions of the merger agreement and the value and form of the merger consideration to be received by the holders of Gateway common stock. After taking into consideration the feasibility of remaining independent, and then embarking on a long and thoughtful process of finding a potential acquirer, Gateway’s board determined that it is advisable and in the best interests of Gateway and its shareholders for Gateway to merge with S&T. Accordingly, Gateway’s board of directors unanimously recommends that Gateway’s shareholders vote “FOR” adoption and approval of the merger agreement.

The board of directors of Gateway has reviewed and considered the terms and conditions of the merger agreement and concluded that they are fair to the shareholders of Gateway and that the merger would be in the best interests of Gateway and its shareholders.

In recommending to its shareholders to approve the acquisition of Gateway by S&T, Gateway’s board of directors consulted with and received advice from Gateway’s senior management and Gateway’s financial and legal advisors. Gateway’s board of directors considered a variety of factors, including the following:

The projected book value per share, value and projected earnings per share of Gateway compared to the value of the merger consideration being offered to Gateway’s shareholders.

The board’s assessment of the existing and future operating environment for community banks in Gateway’s market area, including the likelihood of increasing regulatory burdens on community banking organizations, the economic instability on a national and local level, the slow recovery of the banking industry from the economic slowdown which began in 2007, and the impact of these factors on Gateway’s potential future profitability and strategic options.

The potential future value of Gateway common stock compared to the value of the merger consideration being offered by S&T and the potential trading value of S&T stock.

The board’s belief and perception that a merger with a larger institution would avail Gateway’s customers an increased array of products and services which would result from a larger institution.

The board’s perception that the proposed merger would result in increased liquidity for Gateway shareholders given the fact that S&T common stock is traded on the Nasdaq Stock Market.

The board’s perception that certain factors may limit Gateway’s ability to grow to any significant size through normal growth or by acquisition, including the perceived limitations on Gateway’s ability to raise capital on acceptable terms to fund growth given, among other things, Gateway’s asset size and the lack of liquidity of its common stock.

The comprehensive process conducted by Gateway’s senior management and KBW, Gateway’s financial advisor, to identify potential merger partners, including S&T, and to solicit indications of interest from potential merger partners relating to the terms, including consideration, of a potential business combination.

The prospects for continued employment for Gateway’s employees and the severance and other benefits to be provided to Gateway’s employees who do not remain with S&T after the merger.

After careful consideration and discussion, and taking into consideration the matters discussed during that meeting and during prior meetings of the DNB board of directors, including the factors described under “—DNB’s Reasons for the Merger; Recommendation of the DNB Board of Directors,” the DNB board of directors unanimously determined that the merger with S&T was advisable and in the best interests of DNB and its shareholders and voted unanimously to adopt and approve the merger agreement and the transactions contemplated thereby and recommend that the shareholders of DNB approve the merger agreement and the transactions contemplated thereby.

After careful consideration, at a meeting held on June 5, 2019, the DNB board of directors unanimously determined that the merger agreement and the merger are advisable and in the best interests of DNB and its shareholders and unanimously approved the merger agreement and the transactions contemplated thereby.

In reaching its decision to approve the merger agreement and the transactions contemplated by the merger agreement and recommend that DNB shareholders vote “FOR” the DNB merger proposal, the DNB board of directors evaluated the merger agreement and such other transactions in consultation with DNB’s management, as well as DNB’s financial and legal advisors, and considered a number of factors, both positive and negative, including the following material factors:

In the course of its deliberations, the DNB board of directors also considered potential risks and potentially negative factors concerning the merger, including the following material factors:

the fact that, because the merger consideration is a fixed exchange ratio of 1.22 shares of S&T common stock as set forthfor each share of DNB common stock, DNB shareholders could be adversely affected by a decrease in the merger agreement, permitting Gateway shareholders the ability to participate in a portion of the future performance of the combined company.

The fact that Gateway shareholders receiving S&T common stock will experience substantially increased liquidity given the trading volumeprice of S&T common stock prior to the completion of the merger;

the risks and costs associated with integrating DNB’s business and operations with those of S&T, including the risk of not realizing all of the anticipated benefits of the merger or not realizing them in the expected timeframe;
the risk that the merger may not be consummated or that the closing may be unduly delayed because certain conditions to DNB’s and S&T’s obligations to complete the merger agreement have not been satisfied, including the risk that necessary regulatory approvals or DNB shareholder approval might not be obtained or due to other factors or developments that may be outside of either party’s control;
the potential risk of diverting DNB management’s attention and resources from the operation of DNB’s business to consummation of the merger;
the restrictions on The Nasdaq Global Select Market, and the conduct of DNB’s business prior to the completion of the merger, which, subject to specific exceptions, could delay or prevent DNB from realizing certain business opportunities or taking certain actions with respect to its operations that it would otherwise take absent the proposed merger;

The board’s satisfaction with the terms of the merger agreement after its review of the termseffects on business and conditions of the merger agreement with its legal and financial advisors.

Gateway’s board of directors also considered certain potentially adverse factors in connection with the merger, including the following:

The risks associated with possible delays in obtaining the approval of two-thirds (66 2/3%) of the shareholders of Gateway and necessary regulatory approvals required to complete the transaction.

Provisions of the merger agreement which prohibit Gateway from soliciting further offers, and limit its ability to respond to acquisition proposals from third parties and the obligation of Gateway to pay a termination fee of $875,000 in the event that the merger agreement terminatescustomer relationships as a result of Gateway engaging in such activity.

The fact that the stock considerationpending merger and the anticipated merger-related costs;

the provisions of the merger agreement which provide for a floating exchange ratioprohibiting DNB from soliciting alternative acquisition proposals; and
the possibility that the termination fee payable by DNB to S&T if the merger agreement is terminated under certain circumstances might have the effect of discouraging alternative acquisition proposals or reducing the price offered in any such proposals.

While the DNB board of directors considered the foregoing potentially positive and potentially negative factors, the DNB board of directors concluded that, overall, the potentially positive factors outweighed the potentially negative factors. Accordingly, the DNB board of directors unanimously determined that the merger agreement and the merger are advisable and in the best interests of DNB and its shareholders.

The DNB board of directors based its determination and unanimous recommendation on the totality of the information presented to and factors considered by it, including in its discussions with DNB’s management and DNB’s financial and legal advisors.

The projections furnished to KBW and used by it in certain of its analyses were prepared by Gateway’s and S&T’s senior management teams. Gateway and S&T do not publicly disclose internal management projections of the type provided to KBW in connectionIn rendering PNC’s opinion, PNC assumed, with its review of the merger. As a result, such projections were not prepared with a view towards public disclosure. The projections were based on numerous variables and assumptions, which are inherently uncertain, including factors related to general economic and competitive conditions. Accordingly, actual results could vary significantly from those set forth in the projections.

For purposes of rendering its opinion, KBW assumedDNB’s consent, that in all respects material to its analyses:

KBWdraft reviewed by PNC in any respect material to PNC’s analyses or opinion. PNC further assumed, with DNB’s consent, that the merger will be accountedwould qualify for using the acquisition method under generally accepted accounting principles, and that the merger will qualify as a tax-free reorganization for United StatesU.S. federal income tax purposes.

In performing its analyses, KBWPNC made numerous assumptions with respect to industry performance, general business, economic, market and financial conditions and other matters whichthat are beyond the control of KBW, GatewayPNC, DNB and S&T. Any estimates contained in the analyses performed by KBWPNC are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than those suggested by these analyses. Additionally, estimates of the value of businesses or securities do not purport to be appraisals or to reflect the prices at which such businesses or securities might actually be sold. Accordingly, these analyses and estimates are inherently subject to substantial uncertainty. In addition, the KBWPNC’s opinion was among several factors taken into consideration by the GatewayDNB’s board of directors in making its determination to approve the merger agreement and the merger. Consequently, the analyses described below should not be viewed as determinative of the decision of the GatewayDNB board of directors with respect to the fairness of the consideration.exchange ratio. The exchange ratio was determined through negotiation between DNB and S&T, and the decision of DNB to enter into the merger agreement was solely that of DNB’s board of directors.

The financial analyses performed andsummarized below include information presented in connection with such opinion.tabular format. The tables alone do not constitute a complete description of the financial analyses. The preparation of a fairness opinion is a complex analyticanalytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. Therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. In arriving at its opinion, KBWPNC did not attribute any particular weight to any analysis or factor that it considered, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. The financial analyses summarized below include information presented in tabular format. Accordingly, KBWPNC believes that its analyses and the summary of its analyses must be considered as a whole and that selecting portions of its analyses and factors or focusing on the information presented below in tabular format without considering all analyses and factors or the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the process underlying its analyses and opinion. The tables alone do not constitute a complete descriptionNo company, transaction or business used in PNC’s analyses for comparative purposes is identical to DNB, S&T or the proposed merger and an evaluation of the results of those analyses is not entirely mathematical.

DNB Historical Stock Performance
Relative to DNB Comparable Institutions and cost savings were used to calculate the financial impact that the merger would have on certain projected financial results of S&T. In the course of this analysis, KBW used earnings estimates for S&T for 2013 and 2014 per First Call consensus estimates and used earnings estimates for Gateway for 2013 and 2014 from Gateway management. This analysis indicated that the merger is expected to be accretive to S&T’s estimated earnings per share in 2013 and 2014. The analysis also indicated that the merger is expected to be accretive to book value per share and slightly dilutive to tangible book value per share for S&T and that S&T would maintain well capitalized capital ratios. For all of the above analyses, the actual results achieved by S&T following the merger will vary from the projected results, and the variations may be material.

Discounted Cash Flow Analysis of S&T

PNC performed a discounted cash flow analysis to estimate a range for the implied equity value of projected cash flows to Gateway shareholders from 2012 to 2017 and (2) the present value of the terminal value of Gateway’sS&T common stock. In determining cash flows availablethis analysis, PNC assumed discount rates of 9%, 12% and 15% and calculated terminal values of 12x and 15x estimated earnings per share at the end of seven years. PNC used research analysts’ estimates for S&T and long-term growth rate and other assumptions for S&T provided to shareholders, KBW assumedPNC by the management of S&T. This analysis indicated an implied present value range of S&T common stock of $25.52 per share to $43.26 per share, which are 8.6x and 14.5x, respectively, S&T’s last 12 months earnings per share as of March 31, 2019, and 134% and 227%, respectively, of S&T’s tangible book value per share as of March 31, 2019.

Financial Impact Analysis on S&T

PNC also conducted a financial impact analysis assuming that the merger would close at the end of the fourth quarter of 2019. PNC used historical financial data as of March 31, 2019, or for the three months ended March 31, 2019, as well as financial projections and forecasts for DNB provided to PNC by the management of DNB, the most recent research analysts’ estimates for S&T, the long-term growth rate and other assumptions for S&T provided to PNC by the management of S&T and projected cost savings anticipated by the management of S&T to be realized from the merger. PNC also incorporated other pro forma assumptions as provided by S&T. The analysis indicated that the merger could be dilutive to tangible book value per share as of December 31, 2019 and could be accretive to earnings per share (excluding transaction expenses) for each of calendar years 2020, 2021, 2022 and 2023. All of the results of PNC’s financial impact analysis may vary materially from the actual results achieved by S&T.

TABLE OF CONTENTS

Contribution Analysis

PNC analyzed the relative contribution of S&T and DNB to various pro forma balance sheet growth per Gateway managementitems and assumed that Gateway would maintain a tangible common equity / tangible asset ratio of 8.00% and would retain sufficient earnings to maintain that level. Any earnings in excess of what would need to be retained represented dividendable cash flows for Gateway. In calculating the terminal value of Gateway, KBW applied multiples ranging from 0.75 times to 1.25 times 2017 forecasted tangible book value. This resulted in a range of values of Gateway from $6.41 to $9.22 per share. The discounted cash flow present value analysis is a widely used valuation methodology that relies on numerous assumptions, including asset and earnings growth rates, terminal values and discount rates. The analysis did not purport to be indicativenet income of the actual values or expected valuescombined entity and pro forma market capitalization. This analysis excludes the impact of Gateway.purchase accounting marks and one-time merger costs. The results of PNC’s analysis are set forth in the following table:

GatewayInterests of DNB’s Directors and KBWExecutive Officers in the Merger

In considering the recommendation of the DNB board of directors that DNB shareholders vote to approve the DNB merger proposal, DNB shareholders should be aware that certain DNB directors and executive officers may have interests in the merger that are different from, or in addition to, the interests of DNB shareholders generally. These interests are described below. The DNB board of directors was aware of these interests and considered them, among other matters, in evaluating, negotiating and approving the merger agreement and the transactions contemplated by the merger agreement and in determining to recommend to DNB shareholders that they vote to approve the DNB merger proposal.

49

TABLE OF CONTENTS

Except as otherwise specifically noted, for purposes of quantifying the potential payments described in this section, the following assumptions were used:

the relevant price per share of DNB common stock is $44.76, which is the average closing price per share of DNB common stock as quoted on NASDAQ over the five business days following the first public announcement of the merger on June 5, 2019;
the effective time of the merger is June 30, 2019, which is the assumed date of the closing solely for purposes of the disclosure in this section; and
the employment of each executive officer of DNB is terminated without cause or due to resignation by the executive for good reason (as such terms are used in the relevant agreements described below), in each case immediately following the assumed effective time of June 30, 2019.

For purposes of all of the DNB agreements, arrangements and plans described below, the completion of the merger will constitute a change in control.

For purposes of the disclosure included in this section, DNB’s executive officers (each of whom is also a named executive officer) are William J. Hieb, Gerald F. Sopp, James A. Malloy and Bruce E. Moroney.

Board of Directors of S&T

Immediately following the effective time, S&T will appoint two current members of the DNB board of directors to the S&T board of directors. The two current members of the DNB board of directors who will be appointed to the S&T board of directors have not yet been determined. The persons to be appointed must be designated by the Nominating and Corporate Governance Committee of the S&T board of directors and must otherwise comply with applicable governmental and eligibility requirements for service on the S&T board of directors. Subject to the approval of the S&T board of directors, these two directors will also be nominated for election at the next annual meeting of shareholders of S&T.

Voting Agreements

The directors and certain executive officers of DNB have each entered into an engagement agreement relatingvoting agreements with S&T, solely in his or her capacity as a shareholder of DNB, in which each such person has agreed, among other things, to vote the shares of DNB common stock owned beneficially or of record by him or her in favor of the merger and against any proposal made in competition with the merger, as well as to certain other customary restrictions with respect to the servicesvoting and transfer of his or her shares of DNB common stock. For more information regarding the voting agreements, see “The Merger Agreement—Voting Agreements.”

Director and Officer Indemnification and Insurance

The merger agreement provides that from and after the completion of the merger, the surviving corporation will indemnify and hold harmless all present and former directors, officers and employees of DNB or any of its subsidiaries arising out of the fact that such person is or was a director, officer or employee of DNB or any of its subsidiaries or is or was serving at the request of DNB or any of its subsidiaries as a director, officer, employee or agent of a corporation, partnership, joint venture, trust or other enterprise if the claim pertains to any matter arising, existing or occurring at or before the effective time of the merger (including the merger and the other transactions contemplated by the merger agreement), regardless of whether such claims are asserted before or after the effective time, to the fullest extent permitted by applicable law. Further, the merger agreement requires the surviving corporation to maintain, for a period of six years after completion of the merger, DNB’s existing directors’ and officers’ liability insurance policy or a comparable policy, capped at 250% of the annual premium payments paid on DNB’s current policy. For more information regarding director and officer indemnification and insurance, see “Covenants and Agreements—Director and Officer Indemnification and Insurance.”

Acceleration of Vesting of Restricted Stock Awards

Pursuant to the merger agreement, at the effective time, each restricted stock award in respect of DNB common stock will vest in full and the restrictions thereon will lapse, and will be converted into a right to receive the merger consideration (less applicable tax withholdings) with respect to each share of DNB common stock subject to the award.

50

TABLE OF CONTENTS

For an estimate of the value to be providedreceived by KBWeach of DNB’s named executive officers in respect of their unvested DNB restricted stock awards that will vest in connection with the merger. Gateway paid KBW a cash fee of $50,000 upon executionmerger, see the section entitled “—Potential Payments and Benefits to DNB Named Executive Officers in Connection with the Merger” below. Based on the assumptions described above, the estimated value of the engagement agreement and a cash fee of $100,000 concurrently withunvested DNB restricted stock awards held by DNB’s non-employee directors that would become vested at the renderingeffective time of the Fairness Opinion relatingmerger is $649,020.

DNB restricted stock awards are generally subject to a one-year holding requirement following the vesting date of an award. To the extent that any DNB restricted stock awards have vested prior to the Transaction. Additionally, Gateway has agreedeffective time of the merger and would be subject to such holding period, at the effective time of the merger, the holding period requirement will cease to apply.

Cash Incentive Awards

Each participant in a DNB annual incentive plan or program in respect of 2019, including the named executive officers who participate in the Company’s Executive Incentive Plan, will be entitled to the payment of such incentives based on actual achievement of specific company, business unit and/or personal performance goals through the effective date. The amounts reported in the table below are estimates based on multiple assumptions that may or may not actually occur, including an assumption that the employment of each of the named executive officers is terminated without cause immediately following the completion of the merger.

Change in Control Agreements

Messrs. Hieb, Sopp, Malloy and Moroney are each party to a change in control agreement with DNB and DNB First, National Association (which we refer to as the “change in control agreements”). These change in control agreements provide the named executive officers with severance payments and additional benefits in connection with a change in control transaction. The proposed merger would constitute a “change in control” under the terms of the change in control agreements.

As currently in effect as to each of the named executive officers, the change of control agreements obligate DNB to pay the named executive officer, upon a termination of his employment following a change in control, either by DNB or the successor corporation following the change in control other than for cause, or by the named executive officer for good reason (which termination for good reason must occur within two years of the change in control), a severance payment in an amount equal to KBWa designated multiple of his total annual cash compensation. The applicable multiple of total annual cash compensation is 3.0 for Mr. Hieb, 2.5 for Mr. Sopp, 1.0 for Mr. Malloy and 1.0 for Mr. Moroney.

The change in control agreements defines “total annual cash compensation” as the sum of two elements:

The aggregate amount of (i) base salary, (ii) DNB’s cash contribution toward the cost of medical, life, disability and health insurance benefits and (iii) employer contributions (whether or not matching) under DNB’s qualified defined contribution retirement plans, that was payable to or for the benefit of the named executive officer at any time during the most recent full fiscal year of DNB ended prior to the time the named executive officer becomes entitled to severance payments; and
The aggregate cash bonuses that have been earned by the named executive officer for performance by him during the most recent full fiscal year of DNB (or, in the case of Mr. Hieb, the average of such bonuses over the two most recent full fiscal years of DNB) ended prior to the time the named executive officer becomes entitled to severance payments, but any bonus shall only be included to the extent it has been finally approved and fixed as to amount at the time the name executive officer becomes entitled to severance payments.

The severance payment under the change in control agreements is subject to execution of closinga release of claims and is required to be made in a lump sum within one calendar week following the date of termination (unless required to be paid later pursuant to Section 409A of the TransactionCode), subject to applicable withholding requirements. Under the terms of the change in control agreements, for Messrs. Malloy and Moroney, if the severance payment or payments, either alone or together with other payments which he has the right to receive from DNB, would constitute a cash fee,“parachute payment” (as defined in Section 280G of the Code or Contingent Fee, equalany successor provision), such lump sum severance payment is to $322,500. Pursuantbe reduced to the engagementlargest amount as will result in no portion of the lump sum severance payment under the agreement Gatewaybeing subject to the excise tax imposed by Section 4999 of the Code. In connection with the merger, Mr. Hieb and Mr. Sopp have agreed, notwithstanding the terms of their change in

Each change in control agreement also provides for payment of the named executive officer’s health insurance, HMO or other similar medical provider benefits (excluding any disability plans or benefits) for a designated period after termination of employment. For Messrs. Hieb, Sopp, Malloy and Moroney, this period is 12 months.

Messrs. Hieb and Sopp are participants in individual supplemental executive retirement plans maintained by the Company (which we refer to as the “SERPs”). Each of the SERPs contains identical terms.

Under the terms of the SERP, in the event that Mr. Hieb or Mr. Sopp, as applicable, remains continuously employed by DNB until his 67th birthday, DNB shall pay to him a monthly retirement benefit over a period of 15 years in 180 equal monthly installments commencing on the first day of the first month following his 67th birthday. The monthly retirement benefit will be 2.5% of the average of the sum of Mr. Hieb’s or Mr. Sopp’s base salary and cash bonuses, as applicable, paid to him during the three calendar years ending immediately prior to his 67th birthday, except that the base salary for any year shall never be less than the base salary that was in effect on October 25, 2017.

In the event of a change in control prior to the commencement of benefits under the federal securities laws. DuringSERP, each of Mr. Hieb and Mr. Sopp is entitled to receive payment of a lump sum amount equal to the twopresent value of his age 67 benefit described above, based on his base salary and cash bonuses paid to him during the three calendar years precedingending prior to or with the date of its opinionthe change in control. This lump sum amount is required to Gateway, KBW has not received compensation for investment banking services from neither Gateway nor S&T.be paid on the first day of the month following the date of the change in control. The proposed merger would constitute a “change in control” under the terms of the SERPs.

S&T’s Reasons forFor quantification of the amounts that would be payable to each of Mr. Hieb and Mr. Sopp under his respective SERP, see the section entitled “—Potential Payments and Benefits to DNB Named Executive Officers in Connection with the Merger” below.

S&TPost-Merger Arrangements with Executive Officers

As of the date of this proxy statement/prospectus, none of DNB’s executive officers has an ongoing growth strategy within the Western Pennsylvania market area through new branches and acquisitions of other strong financial institutions.

S&T entered into any agreements or arrangements with S&T regarding continued service with S&T after the effective time. However, it is possible that S&T may enter into employment or other arrangements with certain executive officers of DNB regarding continued service with S&T after the effective time.

Potential Payments and Benefits to DNB Named Executive Officers in Connection with the Merger

The information set forth in the following table is intended to comply with Item 402(t) of the SEC’s Regulation S-K, which requires disclosure of information about certain compensation and benefits payable to each of DNB’s named executive officers that is based on, or otherwise relates to, the merger. The compensation payable to these individuals is the subject of a non-binding advisory vote of DNB shareholders, as described above in “DNB PROPOSALS—PROPOSAL NO. 3: DNB COMPENSATION PROPOSAL.”

The following table sets forth the amount of payments and benefits that each of DNB’s named executive officers would receive in connection with the merger, agreement with Gateway to further implement this strategy, and to improve future earnings. Gateway is a commercial bank with a culture focused on strong asset quality, customer service and earnings, making it similar to S&T’s business model. S&T expectsassuming: (i) that the effective time of the merger togetheris June 30, 2019, which is the assumed date of the closing solely for purposes of the disclosure in this section; (ii) a per share price of DNB common stock of $44.76, which is the average closing price per share over the five business days following the first public announcement of the merger on June 5, 2019; and (iii) the employment of each named executive officer of DNB is terminated without cause or due to resignation with its recent acquisitiongood reason (as such terms are defined in the relevant agreements) immediately following the assumed effective time of Mainline Bancorp, Inc., will further its strategic expansion into Western Pennsylvania markets that itJune 30, 2019.

TABLE OF CONTENTS

S&T’s Dividend Policy

Holders of S&T common stock are entitled to dividends as and when declared by the S&T board of directors out of funds legally available for the payment of dividends. The Nasdaq Global Select Market,S&T board of directors has in the past declared and paid regular dividends on a quarterly basis. However, the payment of future dividends is subject to the discretion of the S&T board of directors, who will consider, among other factors, economic and market conditions, S&T’s financial condition and operating results, and other factors including applicable government regulations.

S&T is a legal entity separate and distinct from its banking and other subsidiaries. A substantial portion of its revenues consist of dividend payments it receives from S&T Bank. The payment of common dividends by S&T is subject to certain requirements and limitations of Pennsylvania law described below. S&T Bank, in turn, is subject to federal and state laws and regulations that limit the amount of dividends it can pay to S&T. In addition, both S&T and S&T Bank are subject to various general regulatory policies relating to the payment of dividends, including requirements to maintain adequate capital above regulatory minimums. The Federal Reserve Board has indicated that banking organizations should generally pay dividends only if the organization’s net income available to common shareholders over the past year has been sufficient to fully fund the dividends, and the prospective rate of earnings retention appears consistent with the organization’s capital needs, asset quality and overall financial condition. Thus, under certain circumstances based upon S&T’s financial condition, its ability to declare and pay quarterly dividends may require consultation with the effectivenessFederal Reserve Board and may be prohibited by applicable Federal Reserve Board guidance.

S&T is incorporated under Pennsylvania law and governed by the PBCL. Under the PBCL, S&T cannot pay dividends if after giving effect to the dividend payments, it would be unable to pay its debts as they become due in the usual course of this Registration Statement,its business or if its total assets would be less than the shares willsum of its total liabilities plus the amount that would be freely transferableneeded, or if it were to be dissolved at the time as of which the dividend is measured, in order to satisfy the preferential rights upon dissolution of shareholders whose preferential rights are superior to those receiving the dividends.

Furthermore, if in the opinion of a federal bank regulatory agency, a depository institution under its jurisdiction is engaged in or is about to engage in an unsafe or unsound practice (which, depending on the Securities Actfinancial condition of 1933, as amended,the depository institution, could include the payment of dividends), the agency may require that the bank cease and desist from the practice. The Federal Reserve Board has similar authority with respect to bank holding companies. Finally, these regulatory authorities have established guidelines with respect to the maintenance of appropriate levels of capital by a bank, bank holding company or savings association under their jurisdiction. Compliance with the Securities Act.standards set forth in these guidelines could limit the amount of dividends that S&T and its subsidiaries may pay in the future.

Notice of Intention to Dissent

If you wish to dissent from the merger, you must do the following:

prior to the vote on the merger agreement by Gateway shareholders at the Gateway special meeting, file a written notice of your intention to demand payment of the fair value of your shares of Gateway common stock if the merger with S&T is completed;

make no change in your beneficial ownership of Gateway common stock from the date you give notice of your intention to demand fair value of your shares of Gateway common stock through the day of the merger; and

not vote your Gateway common stock to adopt the merger agreement at the special meeting.

Simply providing a proxy against or voting against the proposed merger at the special meeting of shareholders will not constitute notice of your intention to dissent. Further, if you submit a proxy, but do not indicate how you wish to vote, you will be deemed to have voted in favor of the merger and your right to dissent will be lost.

Notice to Demand Payment

If the merger is adopted by the required vote of Gateway shareholders, Gateway or S&T will mail a notice to all those dissenting shareholders who gave due notice of their intention to demand payment of the fair value of their shares and who did not vote to adopt the merger agreement. The notice will state where and when dissenting Gateway shareholders must deliver a written demand for payment and where such dissenting shareholder must deposit the certificates for Gateway common stock in order to obtain payment. The notice will include a form for demanding payment and a copy of the relevant provisions of Pennsylvania law. The time set for receipt of the demand for payment and deposit of stock certificates will be not less than 30 days from the date of mailing of the notice.

Failure to Comply with Required Steps to Dissent

You must take each step in the indicated order and in strict compliance with Pennsylvania law in order to maintain your dissenters’ rights. If you fail to follow these steps, you will lose the right to dissent and you will receive the same merger consideration as those Gateway shareholders who do not dissent.

Payment of Fair Value of Shares

Promptly after the effective date of the merger, or upon timely receipt of demand for payment if the closing of the merger has already taken place, S&T will send each dissenting shareholder who has deposited his, her or its stock certificates the amount that S&T estimates to be the fair value of the Gateway common stock held by such dissenting shareholder. The remittance or notice will be accompanied by:

a closing balance sheet and statement of income of Gateway for the fiscal year ending not more than 16 months before the date of remittance or notice, together with the latest available interim financial statements;

a statement of S&T’s estimate of the fair value of Gateway common stock; and

a notice of the right of the dissenting shareholder to demand supplemental payment, accompanied by a copy of the relevant provisions of Pennsylvania law.

Estimate by Dissenting Shareholder of Fair Value of Shares

If a dissenting shareholder believes that the amount stated or remitted by S&T is less than the fair value of the Gateway common stock, the dissenting shareholder must send its estimate of the fair value (deemed a demand for the deficiency) of the Gateway common stock to S&T within 30 days after S&T mails its remittance. If the dissenting shareholder does not file its estimated fair value within 30 days after the mailing by S&T of its remittance, the dissenting shareholder will be entitled to no more than the amount remitted by S&T.

Valuation Proceedings

If any demands for payment remain unsettled within 60 days after the latest to occur of:

the effective date of the merger;

timely receipt by Gateway or S&T, as the case may be, of any demands for payment; or

timely receipt by Gateway or S&T, as the case may be, of any estimates by dissenters of the fair value,

then S&T may file an application, in the Court of Common Pleas of Washington County, Pennsylvania, requesting that the court determine the fair value of the Gateway common stock. If this happens, all dissenting shareholders whose demands have not been settled, no matter where they reside, will become parties to the proceeding. In addition, a copy of the application will be delivered to each dissenting shareholder.

If S&T fails to file the application, then any dissenting shareholder, on behalf of all dissenting shareholders who have made a demand and who have not settled their claim against S&T, may file an application in the name of S&T at any time within the 30-day period after the expiration of the 60-day period and request that the Washington County Court of Common Pleas determine the fair value of the shares. The fair value of the shares as determined by the Washington County Court of Common Pleas may, but need not, equal the dissenting shareholders’ estimates of fair value. If no dissenter files an application, then each dissenting shareholder entitled to do so shall be paid no more than S&T’s estimate of the fair value of the Gateway common stock, and may bring an action to recover any amount not previously remitted, plus interest at a rate the Washington County Court of Common Pleas finds fair and equitable.

S&T intends to negotiate in good faith with any dissenting shareholder. If, after negotiation, a claim cannot be settled, then S&T will file an application requesting that the fair value of the Gateway common stock be determined by the Washington County Court of Common Pleas.

Cost and Expenses

The costs and expenses of any valuation proceedings performed by the Washington County Court of Common Pleas, including the reasonable compensation and expenses of any appraiser appointed by such court to recommend a decision on the issue of fair value, will be determined by such court and assessed against S&T, except that any part of the costs and expenses may be apportioned and assessed by such court against any or all of the dissenting shareholders who are parties and whose action in demanding supplemental payment is dilatory, obdurate, arbitrary, vexatious or in bad faith, in the opinion of such court.

Gateway shareholders wishing to exercise their dissenters’ rights should consult their own counsel to ensure that they fully and properly comply with applicable requirements.

Regulatory Approvals Required for the Merger

TheCompletion of the merger is subject to the prior receipt of all approvals and consents required to be obtained from applicable governmental and regulatory authorities, without certain conditions being imposed by any governmental authority as part of a regulatory approval that would reasonably be likely to have a material adverse effect in respect of S&T and its subsidiaries, taken as a whole, or DNB and its subsidiaries, taken as a whole, in each case measured on a scale relative to DNB and its subsidiaries, taken as a whole.

Gateway’s Directors and Executive Officers Have Financial Interests in the Merger

In considering the recommendation of the Gateway Board of Directors that you vote to adopt the merger agreement and plan, you should be aware that Gateway’s directors and executive officers may have financial interests in the merger that are different from, or in addition to, the interests of the Gateway shareholders generally. Gateway’s Board of Directors was aware of and considered these interests, among other matters, in approving and adopting the agreement and plan of merger. For purposes of all of the Gateway agreements and plans described below, the consummation of the transactions contemplated by the merger agreement generally will constitute a change in control of Gateway.56

Severance Payments and Benefits in Employment Agreements

Gateway previously entered into employment agreements with William J. Burt, Robert S. Kerr and Randolph T. Patterson, which employment agreements were each amended in connection with the signing of the merger agreement, and S&T agreed to assume each employment agreement, as amended.

- 37 -


Mr. Burt’s amended employment agreement provides that he will resign for “good reason” immediately upon the consummation of the merger. Upon such resignation, Mr. Burt will be entitled to receive his current base salary of $200,000 for 24 months, and will receive, for 24 months, a payment each month equal to the COBRA premium cost for the group medical plan coverage currently in effect. Mr. Burt will not be entitled to any bonuses or other incentive compensation following the closing of the merger. Mr. Burt remains subject to a one-year non-competition and non-solicitation covenant following his resignation.

Mr. Kerr and Mr. Patterson’s amended employment agreements each provide that the terms of their employment will be extended until December 31, 2013, or the “Expiration Date.” Effective upon the closing of the merger through November 30, 2012, Mr. Kerr’s base salary will be $195,000, and will increase to $200,000 as of December 1, 2012, and Mr. Patterson’s base salary shall be $142,000, with an increase to $148,000 as of December 1, 2012. Each of Messrs. Patterson and Kerr will be eligible to participate in S&T’s bonus and equity compensation programs. The amended employment agreements of each of Messrs. Kerr and Patterson include severance and change-in-control benefits, including:

TABLE OF CONTENTS

if the employment of Mr. Kerr or Mr. Patterson is terminated without “cause” after closing and prior to February 28, 2013, or the “Conversion Date,” each will be entitled to receive his current base salary for 24 months, and will receive, for 24 months, a payment each month equal to the COBRA premium cost for the group medical plan coverage currently in effect.

if Mr. Kerr or Mr. Patterson are employed by S&T, S&T Bank or any affiliate of S&T, each will receive a “change-in-control” payment of their current base salary for 24 months, payable monthly in accordance with S&T’s payroll practices, regardless of whether Mr. Kerr or Mr. Patterson remain employed by S&T subsequent to the Conversion Date. Such change-in-control payments will be in addition to Mr. Kerr and Mr. Patterson’s base salary for continued employment.

if, after the closing and prior to the Expiration Date, Mr. Kerr or Mr. Patterson are terminated without “cause,” each will continue to receive their current base salary from the date of termination until the Expiration Date, subject to the execution and delivery of a general release to S&T. “Cause” means (i) the commission of a felony or material act involving dishonest, fraud or breach of duty of loyalty tending to bring public disgrace or disrepute; (ii) gross negligence or willful misconduct that is not cured upon notice; (iii) a material breach of the employment agreement or willful failure to perform his duties that is not cured upon notice; (iv) addition to drugs or alcohol if the employee has refused treatment or not successfully completed treatment within the past 12 months; and (v) S&T’s good faith determination that such employee failed to substantially perform his duties or materially violated any of S&T’s and its affiliates policies.

Messrs. Kerr and Patterson remains subject to non-competition and non-solicitation covenants following any termination.

Each of the employment agreements provides that the severance payments and benefits described above will be reduced, as needed, by the minimum amount necessary to ensure that the payments are not “excess parachute payments” under Section 280G of the Internal Revenue Code (which, generally, are subject to an excise tax and are non-deductible by the payor).

Treatment of Stock Options and Warrants

THE MERGER AGREEMENT

The following describes certain aspects of the merger, including certain material provisions of the merger agreement. The following description of the merger agreement is subject to, and qualified in its entirety by reference to, the merger agreement, which is attached to this proxy statement/prospectus as Annex A and is incorporated by reference ininto this proxy statement/prospectus. We urge you to read the merger agreement carefully and in its entirety, as it is the legal document governing the merger.

Explanatory Note Regarding the Merger Agreement

The merger agreement and this merger.

Termssummary of terms are included to provide you with information regarding the terms of the Mergermerger agreement. Factual disclosures about S&T and DNB contained in this proxy statement/prospectus or in the public reports of S&T and DNB filed with the SEC may supplement, update or modify the factual disclosures about S&T and DNB contained in the merger agreement. The merger agreement contains representations and warranties by S&T, on the one hand, and by DNB, on the other hand. The representations, warranties and covenants made in the merger agreement by S&T and DNB were qualified and subject to important limitations agreed to by S&T and DNB in connection with negotiating the terms of the merger agreement. In particular, in your review of the representations and warranties contained in the merger agreement and described in this summary, it is important to bear in mind that the representations and warranties were negotiated with the principal purpose of establishing circumstances in which a party to the merger agreement may have the right not to consummate the merger if the representations and warranties of the other party prove to be untrue due to a change in circumstance or otherwise, and allocating risk between the parties to the merger agreement, rather than establishing matters as facts. The representations and warranties also may be subject to a contractual standard of materiality different from that generally applicable to shareholders and reports and documents filed with the SEC and some were qualified by the matters contained in the confidential disclosure schedules that S&T and DNB each delivered in connection with the merger agreement and certain documents filed with the SEC. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this proxy statement/prospectus, may have changed since the date of the merger agreement.

For the foregoing reasons, the representations and warranties or any descriptions of those provisions should not be read alone or relied upon as characterizations of the actual state of facts or condition of S&T or DNB or any of their respective subsidiaries or affiliates. Instead, such provisions or descriptions should be read only in conjunction with the other information provided elsewhere in this document or incorporated by reference into this proxy statement/prospectus. Please see “Where You Can Find More Information.” S&T and DNB will provide additional disclosures in their public reports to the extent they are aware of the existence of any material facts that are required to be disclosed under federal securities laws and that might otherwise contradict the terms and information contained in the merger agreement and they will update such disclosure as required by federal securities laws.

Additionally, the indemnified parties may retain counsel reasonably satisfactory to them after consultation with S&T. However, S&T retains the right to assume the defense thereof and upon such assumption S&T will not be liable to any indemnified party for any legal expenses of other counsel or any other expenses subsequently incurred in connection with the defense thereof, except that if S&T elects not to assume such defense or counsel or the indemnified party reasonably advises that there are issues which raise conflicts of interest between S&T and the indemnified party, the indemnified party may retain counsel reasonably satisfactory to him after notification and S&T will pay the reasonable fees and expenses. Under the merger agreement, S&T is obligated to pay for only one firm of counsel for all indemnified parties, and S&T is not liable for any settlement effected without its prior written consent (which will not be unreasonably withheld). S&T will have no further obligation to any indemnified party when and if a court of competent jurisdiction ultimately determines, and such determination is final and non-appealable, that indemnification is prohibited by law or to any indemnified party that commits fraud. S&T’s indemnification obligations continue for six years after completion of the merger, but the right to indemnification in respect of any claim asserted within that time period continues until the final disposition of the claim.

The merger agreement requires S&T to maintain in effect for six years after completion of the merger the current rights of Gateway directors, officers and employees to indemnification under the Gateway articles of incorporation or the Gateway by-laws or similar governing documents. The merger agreement also provides that, upon completion of the merger, S&T will indemnify and hold harmless, and provide advancement of expenses to, all past and present officers, directors and employees of Gateway and its subsidiaries in their capacities as such against all losses, claims, damages, costs, expenses, liabilities, judgments or amounts paid in settlement to the fullest extent permitted by applicable laws.

The merger agreement provides that S&T will maintain for a period of three years after completion of the merger Gateway’s current directors’ and officers’ liability insurance policies, or policies of at least the same coverage and amount and containing terms and conditions that are not less advantageous than the current policy, with respect to acts or omissions occurring prior to the effective time of the merger, except that S&T is not required to incur an annual premium expense greater than 200% of Gateway’s current annual directors’ and officers’ liability insurance premium.

Conditions to Complete the Merger

Our respective obligations to complete the merger are subject to the fulfillment or waiver of certain conditions, including:

the adoption of the agreement and plan of merger by the requisite vote of Gateway shareholders;

the approval of the listing of S&T common stock to be issued in the merger on The Nasdaq Global Select Market, subject to official notice of issuance;

the effectiveness of the registration statement of which this proxy statement/prospectus ismerger. Instead, a part with respect to the S&T common stock to be issued in the merger under the Securities Act and the absence of any stop order or proceedings initiated or threatened by the SEC for that purpose;

the receipt by each of S&T and Gateway ofDNB shareholder who otherwise would have received a legal opinion with respect to certain United States federal income tax consequences of the merger;

the receipt and effectiveness of all governmental and other approvals, registrations and consents on terms and conditions that would not have a material adverse effect or be unduly burdensome on S&T, and the expiration of all related waiting periods required to complete the merger;

the absence of any law, statute, regulation, judgment, decree, injunction or other order in effect by any court or other governmental entity that prohibits completion of the transactions contemplated by the merger agreement.

- 48 -


Each of S&T’s and Gateway’s obligations to complete the merger is also separately subject to the satisfaction or waiver of a number of conditions including:

the absence of a material adverse effect on the other party; and

the truth and correctness of the representations and warranties of each other party in the merger agreement, subject to the materiality standard provided in the merger agreement, and the performance by each other party in all material respects of their obligations under the merger agreement and the receipt by each party of certificates from the other party to that effect.

In addition, the obligation of S&T to complete the merger is subject to the expiration or unavailability of rights to demand appraisal under the Pennsylvania Business Corporation Law with respect to at least 90% of the outstanding shares of Gateway common stock (excluding Company-Owned Stock)

We cannot provide assurance as to when or if all of the conditions to the merger can or will be satisfied or waived by the appropriate party. As of the date of this proxy statement/prospectus, we have no reason to believe that any of these conditions will not be satisfied.

Termination of the Merger Agreement

The merger agreement can be terminated at any time prior to completion by mutual consent or by either party in the following circumstances:

if there is a breach by the other party that would cause the failure of the closing conditions, unless the breach is capable of being, and is, cured within 30 days of notice of the breach and the terminating party is not itself in material breach;

if the merger has not been completed by December 31, 2012, unless the failure to complete the merger by that date arises out of or results from the knowing action or inaction of the party seeking to terminate;

if any of the required regulatory approvals are denied (and the denial is final and non-appealable); or

if the common shareholders of Gateway fail to adopt the agreement and plan of merger at the special meeting.

In addition, S&T may terminate the merger agreement if the Gateway board of directors fails to recommend that Gateway shareholders adopt the agreement and plan of merger; withdraws or materially modifies, or proposes to withdraw or materially modify, in a manner adverse to S&T, its recommendation of the merger to shareholders; or recommends a competing merger proposal.

Gateway may terminate the merger agreement within five business days of the Determination Date (Determination Date means the later of (i) the date on which all regulatory approvals, and waivers, if applicable, necessary for consummation of the merger and the transactions contemplated by the merger agreement have been received or (ii) the date of the meeting of Gateway shareholders to consider the merger) if its board of directors determines that both of the following conditions have occurred and gives written notice to S&T of such determination:

the average of the daily closing sales pricesfraction of a share of S&T common stock as reported on Nasdaq forwill receive an amount in cash rounded to the 10 consecutive trading days immediately precedingnearest whole cent. This cash amount will be determined by multiplying (x) the Determination Date is less than 80% of the closing sale price of S&T common stock on the last trading date before the date of the merger agreement; and

the average of the daily closing sales pricesfraction of a share of S&T common stock as reported on Nasdaq for the 10 consecutive trading days immediately preceding the Determination Date is such that the price performance of S&T common stock is lower than the price performance of the Nasdaq Bank Index minus 20%.

- 49 -


However, Gateway may not terminate in these circumstances if S&T exercises its option to increase the number of S&T common shares to be received by Gateway shareholders such that the implied value of the merger would be equivalent to the lesser of $9.22 or $9.22 multiplied by the percentage by which the Nasdaq Bank Index declines over the period starting on the last trading date before the date of the merger agreement and ending on the Determination Date.

Effect of Termination. If the merger agreement is terminated, it will become void, and there will be no liability on the part of S&T or Gateway, except that (1) both S&T and Gateway will remain liable for any willful breach of the merger agreement and (2) designated provisions of the merger agreement, including the payment of fees and expenses, the confidential treatment of information and publicity restrictions, will survive the termination.

Termination Fee

Gateway will pay S&T a $875,000 termination fee in the event that the merger agreement is terminated because (1) the Gateway board of directors fails to recommend that Gateway shareholders adopt the agreement and plan of merger, withdraws or modifies its recommendation in a manner adverse to S&T, or recommends an alternative business combination proposal or (2) the Gateway shareholders fail to adopt the merger agreement because of an act or omission discussed in subsection (1) of this paragraph.

Amendment, Waiver and Extension of the Merger Agreement

Subject to applicable law, the parties may amend the merger agreement by written agreement between Gateway and S&T executed in the same manner as the merger agreement.

At any time prior to the completion of the merger, each of the parties, by action taken or authorized by their respective board of directors, to the extent legally allowed, may:

extend the time for the performance of any of the obligations or other acts of the other party;

waive any inaccuracies in the representations and warranties of the other party; or

waive compliance by the other party with any of the other agreements or conditions contained in the merger agreement.

However, after any approval of the transactions contemplated by the agreement and plan of merger by the Gateway shareholders, no amendments or waivers may be made that would require resubmission of the agreement and plan of merger to the Gateway shareholders.

- 50 -


ACCOUNTING TREATMENT

S&T will account for the merger using the acquisition method under U.S. generally accepted accounting principles. Under the acquisition method of accounting, the tangible and identifiable intangible assets and liabilities of Gateway will be recorded, as of completion of the merger, at their respective fair values. The excess of the purchase price over the net assets acquired will be recorded as goodwill to the extent not allocated to core deposit or other intangibles. Goodwill resulting from the merger will not be amortized but will be reviewed for impairment at least annually. Core deposits and other intangibles with finite useful lives recorded in connection with the merger will be amortized.

Financial statements and reported results of operations of S&T issued after completion of the merger will not be restated retroactively to reflect the historical financial position or results of operations of Gateway.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

General

The following is a summary of the anticipated material United States federal income tax consequences of the merger generally applicable to a holder of Gateway common stock. This discussion is based upon provisions of the Internal Revenue Code, applicable current and proposed United States Treasury Regulations, judicial authorities, and administrative rulings and practice, all as in effect as of the date of this proxy statement/prospectus, as well as representations and facts provided by S&T and Gateway to Arnold & Porter LLP, or Arnold & Porter, counsel to S&T. Future legislative, judicial, or administrative changes or interpretations which may or may not be retroactive, or the failure of any such facts or representations to be true, accurate and complete, may affect the statements and conclusions described in this discussion.

This discussion is not intended to be a complete description of all of the United States federal income tax consequences of the merger and no information is provided with respect to the tax consequences of the merger under any other tax laws, including applicable state, local and foreign tax laws. Further, the following discussion may not apply to a holder of Gateway common stock subject to special treatment under the Internal Revenue Code, including but not limited to a holder of Gateway common stock that is:

a financial institution;

an insurance company;

a dealer or broker in securities or foreign currencies;

a trader in securities who elects mark-to-market accounting;

a tax-exempt organization;

a mutual fund;

a trust;

an estate;

a person who holds shares of Gateway common stock in an individual retirement account (IRA), 401(k) plan or similar tax-favored account;

a person who acquired shares of Gateway common stock on exercise of an employee stock option or otherwise as compensation;

a person whose functional currency for United States federal income tax purposes is not the United States dollar;

a person who is a United States expatriate;

a partnership or other pass-through entity (or a person holding Gateway common stock through a partnership or other pass-through entity); or

a person who holds shares of Gateway common stock as part of a hedge, straddle, conversion or constructive sale transaction.

In addition, this discussion applies only to a holder of Gateway common stock who is holding such stock as a capital asset and who is a “United States person” as defined in Section 7701(a)(30) of the Internal Revenue Code.

No ruling has been or will be requested from the Internal Revenue Service regarding the tax consequences of the merger. Moreover, the opinion of Arnold & Porter described in this discussion is not binding on the Internal Revenue Service, and this opinion would not prevent the Internal Revenue Service from challenging the United States federal income tax treatment of the merger. Because of the complexities of the tax laws in general, and the complexities of the tax consequences associated with the receipt of cash in the merger in particular,

- 52 -


holders of Gateway common stock should consult their tax advisors with respect to the federal, state, local and foreign tax consequences of the merger as they apply to their specific situations. This section is not intended to be tax advice to any shareholder.

Arnold & Porter’s Tax Opinion

In connection with the filing with the SEC of the registration statement of which this proxy statement/prospectus is a part, Arnold & Porter has delivered its opinion addressing the United States federal income tax consequences of the merger as described below. This opinion is based upon the facts, representations and assumptions set forth or referred to in such opinion. In rendering this opinion, Arnold & Porter has relied on representations and facts provided by S&T and Gateway. This opinion is to the effect that:

the merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code;

each holder of Gateway common stock who receives S&T common stock and cash (other than cash in lieu of a fractional share interest in S&T common stock) in the merger in exchange for the holder’s shares of Gateway common stock will recognize the gain, if any, realized by the holder, in an amount not in excess of the amount of cash received (other than cash received instead of a fractional share interest in S&T common stock), but will not recognize any loss on the exchange; and

holders of Gateway common stock who receive cash instead of a fractional share interest in S&T common stock will recognize gain or loss equal to the difference between the cash received and the portion of the basis of the holders’ shares of Gateway common stock allocable to that fractional share interest.

S&T and Gateway’s obligations to consummate the merger are conditioned on the receipt by S&T and Gateway of an additional opinion of Arnold & Porter, dated the closing date of the merger, substantially to the foregoing effect. That opinion will be subject to and based on facts, representations and assumptions set forth or referred to in the opinion. In rendering its closing date opinion, Arnold & Porter may rely on representations and facts provided by S&T and Gateway.

Character of Gain on Exchange of Gateway Common Stock for S&T Common Stock and Cash

For purposes of calculating gain in this transaction, a Gateway shareholder that receives S&T common stock and cash (other than cash received instead of a fractional interest in S&T common stock) must calculate gain or loss separately for each identifiable block of shares exchanged. Such gain or loss will be equal to the sum of the amount of cash and the fair market value of S&T common stock received with respect to that block of shares minus the shareholder’s adjusted tax basis in that block of shares. In addition, a loss realized on one block of shares may not be used to offset a gain realized on another block of shares.

As noted above, in the case of a Gateway shareholder that exchanges his or her shares of Gateway common stock for a combination of S&T common stock and cash pursuant to the merger, such shareholder will recognize the gain, if any, realized by such shareholder in the exchange but not in excess of the amount of cash received. In general, the determination of whether any gain recognized in the exchange should be treated as capital gain or has the effect of a distribution of a dividend depends upon whether, and to what extent, the exchange reduces the shareholder’s deemed percentage stock ownership of S&T. For purposes of this determination, the shareholder is treated as if he or she first exchanged all of his or her shares of Gateway common stock solely for S&T common stock and then S&T immediately redeemed (in a “deemed redemption”) a portion of such S&T common stock in exchange for the cash the shareholder actually received. The gain recognized in the exchange will be treated as capital gain if the deemed redemption (i) is “substantially disproportionate” with respect to the shareholder or (ii) is not essentially equivalent to a dividend.

- 53 -


The deemed redemption should generally be “substantially disproportionate” with respect to a shareholder if the percentage of the outstanding stock of S&T the shareholder owns, actually and constructively, immediately after the deemed redemption is less than 80% of the percentage of the outstanding stock of S&T the shareholder is deemed to own, actually and constructively, immediately before the deemed redemption.

Whether the deemed redemption is “not essentially equivalent to a dividend” with respect to a shareholder will depend on the shareholder’s particular circumstances. In order for the deemed redemption to be “not essentially equivalent to a dividend,” the deemed redemption must result in a “meaningful reduction” in the shareholder’s actual and constructive percentage stock ownership of S&T. In general, that determination requires a comparison of the percentage of the outstanding stock of S&T the shareholder is deemed to own, actually and constructively, immediately before the deemed redemption and the percentage of the outstanding stock of S&T the shareholder actually and constructively owns immediately after the deemed redemption. The Internal Revenue Service has ruled that a minority shareholder (i.e., a shareholder whose relative stock interest is minimal in relation to the number of shares outstanding and who exercises no control with respect to corporate affairs) generally is treated as having a “meaningful reduction” in interest if a cash payment results in at least a relatively minor reduction in the shareholder’s actual and constructive percentage ownership.

Tax Basis and Holding Period

The aggregate tax basis of the S&T common stock received by a Gateway shareholder in the merger (including fractional shares deemed received and redeemed as described below) will be the same as the aggregate tax basis of the shares of Gateway common stock surrendered by such shareholder for the S&T common stock, decreased by the amount of any cash received (other than cash received instead of a fractional share interest in S&T common stock) by the shareholder and increased by the amount of income or gain recognized by the shareholder in the exchange (which does not include gain recognized in respect of fractional shares deemed received and redeemed (as described below)).

Each Gateway shareholder’s holding period in any shares of S&T common stock received in the merger (including any fractional shares deemed received and redeemed as described below) will, in each instance, include the period during which the shares of Gateway common stock surrendered in exchange therefor were held, provided that those shares of Gateway common stock were held as capital assets on the effective date of the merger.

Cash Received in Lieu of a Fractional Share Interest

Cash received by a Gateway shareholder in lieu of a fractional share interest in S&T common stock will be treated as though the fractional share had been received and then redeemed for cash, and in general gain or loss will be recognized, measured by the difference between the amount of cash received and the portion of the basis of the shares of Gateway common stock allocable to such fractional interest. Such gain or loss generally will be long-term capital gain or loss if the holding period for such shares of Gateway common stock was more than one year as of the effective date of the merger. If, however, the receipt of cash instead of a fractional share of S&T common stock has the effect of the distribution of a dividend with respect to a shareholder, part or all of the cash received may be treated as a dividend.

S&T and Gateway

S&T and Gateway will each be a party to the reorganization within the meaning of Section 368(b) of the Internal Revenue Code. As a result, no gain or loss will be recognized by S&T or Gateway as a result of the merger (except for amounts resulting from any required change in accounting methods or any income or deferred gain recognized under the relevant consolidated return regulations).

Backup Withholding

Backup withholding at a 28% rate will generally apply to merger consideration that includes cash if the exchanging Gateway shareholder fails to properly certify that it is not subject to backup withholding, generally

- 54 -


on Internal Revenue Service Form W-9. Certain holders, including, among others, United States corporations, are not subject to backup withholding, but they may still need to furnish a Form W-9 or otherwise establish an exemption. Any amounts withheld from payments to a Gateway shareholder under the backup withholding rules are not additional taxes and will be allowed as a refund or credit against the shareholder’s United States federal income tax liability, provided that the required information is timely furnished to the Internal Revenue Service.

Tax matters are very complicated, and the tax consequences of the merger to each holder of Gateway common stock will depend on the facts of that shareholder’s particular situation. The discussion set forth above does not address all United States federal income tax consequences that may be relevant to a particular holder of Gateway common stock and may not be applicable to holders in special situations. Holders of Gateway common stock are urged to consult their own tax advisors regarding the specific tax consequences of the merger.

- 55 -


PROPOSAL 2—AUTHORIZATION TO VOTE ON ADJOURNMENT OR OTHER MATTERS

General

If, at the Gateway special meeting, the number of shares of Gateway common stock, present in person or by proxy, is insufficient to constitute a quorum or the number of shares of Gateway common stock voting in favor is insufficient to adopt the merger agreement, Gateway management intends to move to adjourn the special meeting in order to enable the Gateway board of directors more time to solicit additional proxies. In that event, Gateway will ask its shareholders to vote only upon the adjournment proposal and not the proposal relating to adoption of the merger agreement.

In this proposal, Gateway is asking you to grant discretionary authority to the holder of any proxy solicited by the Gateway board of directors so that such holder can vote in favor of the proposal to adjourn the special meeting to solicit additional proxies. If the shareholders of Gateway approve the adjournment proposal, Gateway can adjourn the special meeting, and any adjourned session of the special meeting, and use the additional time to solicit additional proxies, including the solicitation of proxies from shareholders who have previously voted.

If the special meeting is adjourned, no notice of the adjourned meeting is required to be given to shareholders, other than an announcement at the special meeting of the place, date and time to which the meeting is adjourned.holder would otherwise be entitled by (y) the S&T share value.

Vote Required

Pursuant to Gateway’s by-laws, a meeting may be adjourned by the affirmative vote of at least a majority of the votes that all shareholders present at the special meeting, in person or represented by proxy, are entitled to cast. Abstentions and broker non-votes will not affect the vote on the adjournment proposal.

Recommendation of the Gateway Board of Directors

The Gateway Board of Directors recommends a vote “FORImmediately following the proposal to authorize the board of directors to adjourn the special meeting of shareholders to alloweffective time, for the further solicitation of proxies to approve the adoption of the merger agreement.

Gateway’s results of operations depend primarily on net interest income. Net interest income is the difference between interest income earned on interest-earning assets (loans and investment securities) and the interest paid on interest-bearing liabilities (deposits and short-term borrowings). Net interest income is directly impacted by the market interest rate environment, the shape of the market yield curve, timing of placement and repricing of interest-earning assets and interest-bearing liabilities and prepayment of loans. Results of operations are also directly affected by general economic conditions.

Net Income. Net income for the first three months of 2012 increased to $176,000 compared to $120,000 for the same period in 2011, an increase of $56,000, or 46.7%. Net income per share improved to $0.10 for the first three months of 2012 compared to $0.07 for the same period in 2011. The improvement in earnings was primarily attributable to lower other operating expenses and a lower provision for loan losses.

Net Interest Income and Margin.Net interest income represents the excess of interest income from earning assets less interest expense on interest bearing liabilities. Net interest margin is the percentage of net interest income to earning assets. Net interest income and net interest margin are affected by fluctuations in interest rates and by changes in the amounts and mix of earning assets and interest bearing liabilities. Net interest income for the three months ended March 31, 2012 decreased slightly by $5,000 or 0.5% compared to the same period in 2011, while the net interest margin increased to 3.43% from 3.38% for the respective periods. The decrease in net interest income was due primarily to a lower volume of average earning assets, the result of lower deposit funding between the periods, offset to some extent by a higher net interest margin, the result of a decrease in the average rate for sources of funds which more than offset a lower yield on earning assets.

Interest Income.Interest income for the three months ending March 31, 2012 decreased by $75,000 or 5.9% to $1,202,000 from $1,277,000 for the same period in 2011. This was due to a decrease in average earning assets and a decrease in the average yield on loans. ‘Average’ earning assets decreased $2.4 million or 2.0%, to $117.6 million for the first three months of 2012 from $120.0 million for the same period in 2011. The average loan yield dropped to 4.61% for the first three months of 2012 versus 4.97% for the same period in 2011. Interest rates have generally declined throughout the periods and are at or near all-time lows. This extremely low interest rate environment is exerting downward pressure on loan yields in three ways. First, as variable rate loans reach repricing dates, yields are reduced. Second, new loans added are at rates lower than those originated in prior years. Finally, borrowers with fixed rates loans refinance existing loans into new lower rate loans. Offsetting the impact of a lower yield on loans to some extent was an increase in average loans outstanding between the periods. ‘Average’ loans were $101.2 million for the first three months of 2012 versus $97.9 million for the same period in 2011, an increase of $3.3 million or 3.4%.

Interest Expense.Interest expense for the three month period ended March 31, 2012 decreased by $70,000 or 26.6% to $194,000 from $264,000 during the same period in 2011. The decrease was due to an overall lower average rate paid and lower overall volume of interest bearing liabilities. The average rate paid on interest bearing liabilities was 0.89% for the first three months of 2012 versus 1.16% for the same period in 2011, while average interest bearing liabilities decreased $4.3 million or 4.7% between the periods.

Provisions for Loan Losses. Provisions for loan losses charged to operations are based on management’s judgment after considering a variety of factors, including current economic conditions, diversification of the loan portfolio and delinquency status. Also considered by management in determining the amounts charged to operations are the evaluations done by the independent loan review function, regulators’ analysis performed in connection with regulatory examinations, previous experience and the general financial condition of the borrower. No provisions were charged to operations during the first three months of 2012 compared to $33,000 for the same period in 2011. The decrease in the provision for loan losses reflects the adequacy of the allowance for loan losses in relation to the risk inherent within the portfolio. For further comments about Gateway’s credit risk, see the discussion under “Loan Quality and Allowance for Loan Losses.”

Other Operating Income.Other operating income for the three months ended March 31, 2012 was $14,000 compared to $17,000 for the same period in 2011. The decrease is related to timing of cash collection on service charges on deposit accounts and certain other transaction fees.

Operating Expenses. Total operating expenses for the three months ended March 31, 2012 were $846,000 compared to $877,000 for the same period in 2011, a decrease of $31,000 or 3.6%. Decreases in data processing, FDIC insurance premiums and occupancy/equipment costs were partially offset by increases in salaries and benefits and Pennsylvania shares tax expense.

Comparing the three months ended March 31, 2012 with the same period in 2011, the following discussion further breaks down the variances in other operating expenses. Data processing decreased to $57,000 from $75,000, a $18,000 or 24.0% decrease, related to lower costs post an upgrade to the FiServ operating system, which was completed around mid-year 2011. FDIC insurance premiums are down to $15,000 from $32,000, a decrease of $17,000 or 53.1%, the result of a revised FDIC calculation in June 2011 that resulted in adjusted premiums in April 2011 carried forward. Occupancy/equipment costs were $135,000 versus $147,000, a decrease of $12,000 or 8.2%, due to lower depreciation expense on equipment, the terms of which expired during the second half of 2011. Salaries and benefits costs increased to $471,000 from $463,000, a $8,000 or 1.7% increase, which consists of normal increases in salaries and wages, health care insurance and other employee benefits. Pennsylvania shares tax was $39,000 versus $34,000, an increase of $5,000 or 14.7%, due to growth in the shareholders’ equity and in the assets of the company over the five year average from which the tax is based.

Income Taxes. Gateway has been in existence since May 2004 and has accumulated a net operating loss since its inception. As such, there is no tax expense per books at Gateway.

Net Income. Net income increased to $621,000 for the year ended December 31, 2011 compared to net income of $448,000 for the year ended December 31, 2010, an increase of $173,000, or 38.6%. Net income per share improved to $0.36 for the full year 2011 compared to $0.26 for 2010. The improvement in earnings was primarily attributable to a lower provision for loan losses and higher net interest income offset slightly by higher other operating expenses and lower other operating income.

Net Interest Income and Margin.Net interest income for the year ended December 31, 2011 increased by $117,000 or 3.0% compared to the same period in 2011, while the net interest margin increased to 3.43% from 3.24% for the respective periods. The increase in net interest income and margin was due primarily to a decrease in the average rate paid on interest bearing liabilities, which more than offset a lower yield on earning assets and the negative impact of lower average earning assets. Interest rates were affected by lower overall rates that continued to decline during the year. Earning assets were impacted by lower average interest bearing liabilities between the periods.

Interest Income.Interest income for the year ended December 31, 2011 decreased by $472,000 or 8.6% compared to the same period in 2011. This was due to a decrease in the average yield on loans and investments, and a decrease in average earning assets. The yield on loans averaged 4.85% in 2011 versus 5.12% in 2010 while the investments yield averaged 1.89% in 2011 versus 2.90% in 2010. As noted in previous discussion, interest rates have generally declined throughout the year and affected loan and investment yields in various ways. In addition to lower yields, the level of earning assets decreased to average $118.0 million in 2011 versus $121.2 million in 2010.

Interest Expense.Interest expense for the full year 2011 decreased by $589,000 or 38.3%, to $949,000 in 2011 from $1,538,000 in 2010. The decrease was due to an overall lower average rate paid and lower overall volume of interest bearing liabilities. The average rate paid on interest bearing liabilities was 1.07% for 2011 versus 1.62% for 2010, while average interest bearing liabilities decreased $5.9 million or 6.3% between the periods.

Provisions for Loan Losses. Provisions for loan losses charged to operations are based on management’s judgment after considering a variety of factors, including current economic conditions, diversification of the loan portfolio and delinquency status. Also considered by management in determining the amounts charged to operations are the evaluations done by the independent loan review function, regulators’ analysis performed in connection with regulatory examinations, previous experience and the general financial condition of the borrower. Provision expense was $63,000 in 2011 versus $222,000 in 2010 and reflects the adequacy of the allowance for loan losses in relation to the risk inherent within the portfolio. For further comments about Gateway’s credit risk, see the discussion under “Loan Quality and Allowance for Loan Losses.”

Other Operating Income.Other operating income for 2011 was $79,000 compared to $87,000 in 2011. The decrease is related to timing of cash collection on service charges on deposit accounts and certain other transaction fees.

Other Operating Expenses. Total operating expenses for the year ended December 31, 2011 were $3,444,000 compared to $3,349,000 for the same period in 2011, an increase of $95,000 or 2.8%. Increases in salaries and benefits, data processing, Pennsylvania shares tax expense and certain other operating expenses were partially offset by decreases in FDIC insurance premiums and occupancy/equipment costs.

Comparing the full years 2011 and 2010, the following discussion further breaks down the variances in other operating expenses. Salaries and benefits costs increased to $1,774,000 from $1,685,000, a $89,000 or 5.3% increase, which consists of normal increases in salaries and wages, health care insurance and other employee benefits. Data processing increased to $330,000 from $293,000, a $37,000 or 12.6% increase, related to one-time costs related to a conversion upgrade of the bank’s operating system which was completed mid-year 2011, offset to some extent by lower overall costs under the new system post conversion. Pennsylvania shares tax

- 62 -


was $139,000 versus $125,000, an increase of $14,000 or 11.2%, due to growth in the shareholders’ equity and the assets of the company over the five years average from which the tax is based. Increased ‘other ‘operating expenses was impacted by certain one-time costs during 2011; these included consulting fees paid related to the sale of the company and employee costs related to the system conversion in 2011 for travel, lodging, etc. FDIC insurance premiums are down to $81,000 from $136,000, a decrease of $55,000 or 40.4%, the result of a revised FDIC calculation in June 2011 that resulted in adjusted premiums in April 2011 carried forward. Occupancy/equipment costs were $555,000 versus $580,000, a decrease of $25,000 or 4.3%, due to lower depreciation expense on equipment, the terms of which expired during the second half of 2011.

Income Taxes. Gateway has been in existence since May 2004 and has accumulated a net operating loss since its inception. As such, there is no tax expense per books at Gateway for either 2011 or 2010.

Balance Sheet. Total assets as of March 31, 2012 was $124,107,000, an increase of $3,846,000 or 3.2% compared to total assets of $120,261,000 at December 31, 2011. Total assets increased due to higher cash on hand and in banks and investments due to higher deposits and capital between the periods.

Net loans remained relatively flat between the periods, loans at $100,042,000 at March 31, 2012 and $100,035,000 at year end 2011. Commercial loans increased slightly while consumer loans had a slight decrease.

Total investments increased by $995,000 or 11.0% between the periods. The primary purpose of the investment portfolio is to provide a source of liquidity sufficient to meet loan funding demands and deposit withdrawals, and to secure certain public deposits. Cash on hand and in banks also serves as a source of liquidity and to meet daily operational needs. Cash on hand and in banks can fluctuate on a daily basis and between periods of comparison, depending on these operational needs and customer demands.

Gateway’s deposits are comprised of demand deposits, NOW accounts, money market accounts, savings accounts and other time deposits obtained from individuals and businesses within the communities where branch offices are located. Deposits increased by $3,664,000 or 3.8%, when comparing March 31, 2012 to December 31, 2011. The principal drivers to this increase were higher demand deposits and money market accounts offset slightly by lower NOW accounts and time deposits.

Loan Quality and Allowance for Loan Losses.Gateway did not have any chargeoffs for the first quarter 2012, or past-due or non-accrual loans as of March 31, 2012. The allowance for loan losses at March 31, 2012 was $1,450,000 or 1.43% of total loans outstanding, which remains unchanged from the allowance at December 31, 2011, which also represented 1.43% of total loans outstanding. Management believes reserve levels are adequate to absorb any possible losses in the loan portfolio.

Balance Sheet. Total assets as of December 31, 2011 was $120,261,000, a decrease of $2,207,000 or 1.8% compared to total assets of $122,468,000 at December 31, 2010. Total assets decreased due to lower cash on hand and in banks and investments due to lower deposits offset to some extent by higher borrowed funds and capital between the periods.

Net loans increased between the periods, rising to $100,035,000 at year end 2011 from $98,308,000 at year end 2010, an increase of $1,727,000 or 1.8%. An increase in commercial loans more than offset a decrease in consumer loans.

Total investments decreased by $1,922,000 or 17.6% between the periods. The primary purpose of the investment portfolio is to provide a source of liquidity sufficient to meet loan funding demands and deposit withdrawals, and to secure certain public deposits. Cash on hand and in banks also serves as a source of liquidity and to meet daily operational needs. Cash on hand and in banks can fluctuate on a daily basis and between periods of comparison, depending on these operational needs and customer demands.

Gateway’s source of funding is deposits and borrowed funds. Deposits are comprised of demand deposits, NOW accounts, money market accounts, savings accounts and other time deposits obtained from individuals and businesses within the communities where branch offices are located and contiguous counties. Deposits decreased by $7,577,000 or 7.3%, when comparing year end 2011 to year end 2010. The principal driver to this decrease was lower time deposits offset to some extent by higher demand deposits. Time deposit runoff related to a 18-month CD special promotion that the bank chose not to continue as these time deposits matured in late 2011. Borrowed funds increased by $4,555,000 or 131.0% between the periods. Borrowed funds consist of term funding from the Federal Home Loan Bank of Pittsburgh and securities sold under agreements to repurchase; both of these sources reflected increases between the periods.

Loan Quality and Allowance for Loan Losses.Gateway did not have any chargeoffs in 2011, or past-due or non-accrual loans as of December 31, 2011. The allowance for loan losses at December 31, 2011 was $1,450,000 or 1.43% of total loans outstanding, versus an allowance of $1,387,000 at December 31, 2010 or 1.39% of total loans. Management believes reserve levels are adequate to absorb any probable losses in the loan portfolio.

Non-Performing Assets

Non-performing assets include non-accrual loans, restructured loans, loans 90 days past due which are still accruing interest and other real estate owned (OREO). Non-accrual loans represent loans where interest accruals

- 64 -


have been discontinued. Restructured loans are loans in which the borrower has been granted a concession on the interest rate or the original repayment terms due to financial distress and the loan is performing according to the revised terms. Gateway had no non-performing assets as of March 31, 2012, December 31, 2011, or December 31, 2010.

Capital Resources

Gateway seeks to maintain a strong capital base to support growth, to provide stability to current operations and to promote public confidence. Stockholders’ equity at March 31, 2012 increased to $15,383,000 versus $15,175,000 at December 31, 2011 and $14,299,000 at December 31, 2010. Increases in stockholders’ equity result from net income, as Gateway did not pay dividends during the periods. Gateway’s capital position was well above all regulatory requirements as of March 31, 2012, December 31, 2011 and December 31, 2010.

Regulatory Capital

Gateway is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on the financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, Gateway must meet specific capital guidelines that involve quantitative measures of assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weighting and other factors. Failure to meet capital requirements can initiate regulatory action.

Quantitative measures established by regulators to ensure capital adequacy require the maintenance of minimum amounts and ratios (set forth in the table below) of Total Capital and Tier I Capital (as defined by the regulators) to risk-weighted assets (as defined), and of Tier I Capital (as defined). Management believes, as of March 31, 2012, December 31, 2011 and December 31, 2010, that Gateway meets all capital adequacy requirements to which they are subject.

As of March 31, 2012, December 31, 2011 and December 31, 2010, Gateway was categorized as well capitalized under the regulatory framework for prompt corrective action by regulatory agencies. To be categorized as well capitalized, Gateway must maintain minimum total risk-based, Tier I risk-based and Tier I leverage ratios as set forth in the following table (dollar figures are in thousands). There are no conditions or events since these periods that management believes have changed those categories.

Off-Balance Sheet Arrangements

Gateway, in the normal course of business, is party to financial instruments with off-balance sheet risk. These instruments are required to meet the financial needs of its customers and include such items as unused lines of credit, letters of credit, and other loan commitments. The instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the financial statements.

Gateway’s exposure to credit loss, in the event of nonperformance by the other party to the financial instrument for commitments to extend credit, is represented by the contractual or notional amount of those instruments, although losses are not anticipated. Gateway uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. The following table identifies the contract or notional amount of these instruments:

Executive Overview

Gateway Bank

   March 31,  December 31,
(Dollars in thousands)  2012  2011  2010

Financial instruments whose contract amounts represent risk:

      

Commitments to extend credit

  $    24,331  $    23,270  $    20,880

Interest rate range

  2.00% to 13.50%  2.00% to 13.50%  2.00% to 13.50%

Standby letters of credit

  $     1,705  $     1,635  $     1,600

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Gateway evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by Gateway upon extensions of credit, is based on management’s credit evaluation of the customer. Collateral held varies but may include accounts receivable, inventory, property, plant and equipment and income producing commercial properties. On loans secured by commercial real estate, Gateway generally requires loan to value ratios of no more than 80%. On loans secured by owner-occupied residential properties, Gateway generally requires loan to value ratios not in excess of 90%.

Standby letters of credit are conditional commitments issued by Gateway to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing and similar transactions. The terms of the letters of credit vary and may have renewal features. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. Gateway holds collateral supporting those commitments for which collateral is deemed necessary.

Loans

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at their outstanding unpaid principal balances net of unearned interest and an allowance for loan losses. Interest income is accrued on the unpaid principal balance. Loan origination fees are deferred and recognized as an adjustment of the yield (interest income) of the related loans. Gateway generally amortizes these amounts over the contractual life of the loan.

The accrual of interest is generally discontinued when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about further collectability of principal or interest,

- 66 -


even though the loan is currently performing. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan is placed on non-accrual status, unpaid interest credited to income in the current year is reversed and unpaid interest accrued in prior years is charged against the allowance for loan losses. Interest received on non-accrual loans generally is either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal. Generally, loans are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable time and the ultimate collectability of the total contractual principal is no longer in doubt.

Allowance for Loan Losses

The allowance for loan losses represents the amount which management estimates is adequate to provide for probable losses inherent in its loan portfolio. The allowance method is used in providing for loan losses. Accordingly, all loan losses are charged to the allowance, and all recoveries are credited to it. The allowance for loan losses is established through a provision for loan losses charged to operations. The provision for loan losses is based on management’s periodic evaluation of individual loans, economic factors, past loss experience, changes in the composition and volume of the portfolio, and other relevant factors. The estimates used in determining the adequacy of the allowance for loan losses, including the amounts and timing of future cash flows expected on impaired loans, are particularly susceptible to change in the near term.

Impaired loans are commercial and commercial real estate loans for which it is probable that Gateway will not be able to collect all amounts due according to the contractual terms of the loan agreement. Gateway individually evaluates such loans for impairment and does not aggregate loans by major risk classifications. Factors considered by management in determining impairment include payment status and collateral value. The amount of impairment for these types of loans is determined by the difference between the present value of the expected cash flows related to the loan using the original interest rate and its recorded value, or as a practical expedient in the case of collateralized loans, the difference between the fair value of the collateral and the recorded amount of the loans. When foreclosure is probable, impairment is measured based on the fair value of the collateral.

The definition of “impaired loans” is not the same as the definition of “nonaccrual loans,” although the two categories overlap. Gateway may choose to place a loan on nonaccrual status due to payment delinquency or uncertain collectability, while not classifying the loan as impaired, provided the loan is not a commercial or commercial real estate classification.

Loans secured by one-to-four family properties and all consumer loans are large groups of smaller-balance homogeneous loans and are measured for impairment collectively. Loans that experience insignificant payment delays, which are defined as 90 days or less, generally are not classified as impaired. Management determines the significance of payment delays on a case-by-case basis, taking into consideration all circumstances concerning the loan, the creditworthiness and payment history of the borrower, the length of the payment delay, and the amount of shortfall in relation to the principal and interest owed.

The general component covers non-impaired loans, which management determines by segmenting the loan portfolio into the following pools: commercial loans; commercial real estate loans; first lien consumer real estate loans; subordinate lien consumer real estate loans; and consumer loans. Certain qualitative factors are then added to any historical allocation percentage applied to each pool to obtain the adjusted factor to be applied to nonclassified loans. The following qualitative factors are analyzed for each portfolio segment: levels of and trends in delinquencies, trends in volume and terms, trends in credit quality ratings, changes in management and lending staff, economic trends, and concentrations of credit.

Pennsylvania Anti-Takeover Provisions

Under Pennsylvania business corporation law, certain anti-takeover provisions apply to Pennsylvania “registered corporations” (e.g., publicly traded companies) including those relating to (i) control share acquisitions, (ii) disgorgement of profits by certain controlling persons, (iii) business combination transactions with interested shareholders and (iv) the rights of shareholders to demand fair value for their stock following a control transaction. Pennsylvania law allows registered corporations to opt-out of any of these anti-takeover provisions. S&T is a registered corporation under the PBLC and has opted out of the anti-takeover provisions listed in (i) and (ii) above. Gateway is not a registered corporation and is therefore not subject to these anti-takeover provisions. A general summary of the applicable anti-takeover provisions is set forth below.

Control Share Acquisitions. Pennsylvania law limits control share acquisitions relating to the act of acquiring for the first time voting power over voting shares (other than shares owned since January 1, 1988 and any additional shares distributed with respect to such shares) equal to at least 20%, 33 1/3% and 50% of the voting power of the corporation. Once a control share acquisition has occurred, then all shares in excess of the triggering threshold, plus shares purchased at any time with the intention of acquiring such voting power and shares purchased within 180 days of the date the triggering threshold was exceeded, are considered control shares. Control shares cannot vote either until their voting rights have been restored by two separate votes of the shareholders, described below, at a meeting or until they have been transferred to a person who does not thereby also become the holder of control shares.

The holder of control shares may wait until the next annual or special meeting after the acquisition took place to submit the request for the restoration of voting rights to the shareholders, or the acquiring person may accelerate the process by agreeing to underwrite the cost of a special meeting of shareholders for that purpose. In either case, the acquiring person is required to furnish for distribution to the shareholders an information statement containing a detailed disclosure concerning the acquiring person, its intentions with respect to ownership of securities of the corporation and other matters. As an alternative, a person proposing to make a control share acquisition may request prospective approval by the shareholders of the exercise of the voting rights of the shares proposed to be acquired. Two shareholders’ votes are required to approve the restoration of voting rights: (i) the approval of an absolute majority of all voting power must be obtained, and all voting shares are entitled to participate in this vote; and (ii) the approval of an absolute majority of all disinterested shareholders must be obtained.

For a period of 24 months after the later of (i) a control share acquisition by an acquiring person who does not properly request consideration of voting rights, or (ii) the denial of such a request or lapse of voting rights, the corporation may redeem all the control shares at the average public market sales price of the shares on the date notice of the call for redemption is given by the corporation.

- 72 -


Disgorgement of Profits by Certain Controlling Persons. Pennsylvania law regarding disgorgement of profits by certain controlling persons applies in the event that (i) any person or group publicly discloses that the person or group may acquire control of the corporation, or (ii) a person or group acquires (or publicly discloses an intent to acquire) 20% or more of the voting power of the corporation and, in either case, sells shares within 18 months thereafter. Any profits from sales of equity securities of the corporation received by the person or group during such 18-month period will belong to the corporation if the securities that were sold were acquired during the 18-month period or within 24 months prior thereto.

Business Combination Transactions with Interested Shareholders. Pennsylvania law prohibits certain business combinations with certain ‘interested shareholders,’ persons who acquire the direct or indirect beneficial ownership of shares entitled to cast at least 20% of the votes entitled to be cast for the election of directors. A corporation subject to this provision may not effect mergers or certain other business combinations with the interested shareholder for a period of five years, unless:

the business combination or the acquisition of stock by means of which the interested shareholder became an interested shareholder is approved by the corporation’s board of directors prior to such stock acquisition;

the business combination is approved by the affirmative vote of the holders of all the outstanding common shares of the corporation; or

the business combination is approved by the affirmative vote of the holders of a majority of all shares entitled to vote, excluding votes of shares held by the interested shareholders, and at the time of such vote, the interested shareholder is the beneficial owner of at least 80% of the voting shares of the corporation. This exception applies only if the value of the consideration to be paid by the interested shareholder in connection with the business combination satisfies certain fair price requirements.

After the five-year restricted period, an interested shareholder of the corporation may engage in a business combination with the corporation if (i) the business combination is approved by the affirmative vote of a majority of the shares other than those beneficially owned by the interested shareholder and its affiliates, or (ii) the merger is approved at a shareholders meeting and certain fair price requirements are met.

Rights of Shareholders to Demand Fair Value for Stock Following a Control Transaction.Pennsylvania law regarding the ability of shareholders to dispose of their stock following a control transaction provides, generally, that a person or group that acquires more than 20% of the voting power to elect directors of the corporation is a controlling person and must give prompt notice to each shareholder of record. The other shareholders are then entitled to demand that the controlling person pay them the fair value of their shares under specified procedures. Fair value may not be less than the highest price paid per share by the controlling person at any time during the 90-day period ending on and including the date on which the controlling person became such, plus any increment representing any value, such as a control premium, that is not reflected in such price.

Voting Rights

Amendment of articles of incorporation.

Pennsylvania law provides that shareholders of a registered corporation, such as S&T, are not entitled by statute to propose amendments to the articles of incorporation. By contrast, under Pennsylvania law, an amendment to the articles of incorporation for an “unregistered corporation,” such as Gateway, can only be proposed (1) by adoption by the board of directors of a resolution setting forth the proposed amendment; or (2) unless otherwise provided in the articles, by petition of shareholders entitled to cast at least 10% of the votes that all shareholders are entitled to cast on the proposed amendment. The shareholder petition must set forth the proposed amendment, be directed to the board of directors and filed with the secretary of the corporation.

Except where the approval of the shareholders is unnecessary, the board of directors will then direct that the proposed amendment be submitted to a vote of the shareholders entitled to vote on the proposed amendment. An

- 73 -


amendment proposed pursuant to paragraph (2) above is required to be submitted to a vote either at the next annual meeting held not earlier than 120 days after the amendment is proposed or at a special meeting of the shareholders called for that purpose by the shareholders.

Under Pennsylvania law, an amendment to the articles of incorporation requires the approval of the board of directors and, exceptof S&T, the two appointed directors will be nominated for election at the next annual meeting of shareholders of S&T.

Officers

The officers of S&T in limited cases where a greater voteoffice immediately prior to the effective time, together with such additional persons as may thereafter be required,appointed, shall serve as the affirmative vote of a majorityofficers of the votes cast by all shareholders entitled to vote onsurviving corporation from and after the mattereffective time of the merger in accordance with the bylaws of S&T.

Treatment of DNB Equity Awards

At the effective time, each restricted stock award in respect of DNB common stock will vest in full and the affirmative voterestrictions thereon will lapse, and will be converted into a right to receive the merger consideration (less applicable tax withholdings) with respect to each share of a majority of the votes cast by all shareholders within each class or series of shares if such class or series is entitled to vote on the matter as a class.

Gateway. Gateway has not opted-out of the statutory process by which shareholders of an unregistered corporation may propose amendments to its articles of incorporation. Certain of Gateway’s articles may not be amended unless first approved by the affirmative vote of (a) the holders of at least 80% of the outstanding shares ofDNB common stock of Gateway; provided, that such transaction has received the prior approval of at least the majority of all members of the board of directors; or (b) the holders of at least 66 2/3% of the outstanding shares of common stock of Gateway; provided, that such transaction has received the prior approval of at least 80% of all of the members of the board of directors.

S&T. S&T’s shareholders are not entitled by statute to propose amendments to the articles of incorporation. S&T’s articles of incorporation may be amended as provided under Pennsylvania law, with the following exception: any amendment to Article 9 (Classification of Directors) or Article 12 (Shareholder Action) requires the affirmative vote of holders of at least 66 2/3% of the votes that all shareholders are entitled to cast thereon at a regular or special meeting of shareholders.

Amendment of by-laws.

Gateway. Gateway’s by-laws may be amended or repealed as the board of directors may deem necessary or desirable (so long as such changes are consistent with the Pennsylvania law and its articles of incorporation) subject to the statutory poweraward.

Closing and Effective Time of the shareholders to change such action, butMerger

The merger will be completed only upon the affirmative vote of the holders of at least 75% of the outstanding shares of Gateway, which votes are cast at a regular or special meeting of the shareholders duly convened after noticeif all conditions to the shareholders of that purpose.

S&T. S&T’s by-laws may be amended by a majority vote of the board of directors at any regular or special meeting of the board duly convened.

Required Vote for Certain Business Combinations.

Gateway. A plan of merger consolidation, share exchange, liquidation, or dissolution of Gateway, or any action that resultsdiscussed in the sale or other disposition of all or substantially all of Gateway’s assets, shall not be valid unless first approved by the affirmative vote of (a) the holders of at least 80% of the outstanding shares of common stock; provided, that such transaction has received the prior approval of at least a majority of the members of the board of directors; or (b) the holders of at least 66 2/3% of the outstanding shares of common stock; provided, that such transaction has received the prior approval of at least 80% of all of the members of the board of directors.

S&T. Any plan or proposal for the merger, consolidation, liquidation or dissolution of S&T, or any action that would result in the sale or other disposition of all or substantially all of the assets of S&T, will require the affirmative vote of the holders of at least 66 2/3% of the outstanding shares of common stock.

Regulatory Matters

S&T and DNB have agreed to use, and to cause their respective subsidiaries to use, their respective reasonable best efforts to (1) take, and assist and cooperate with the other party in taking, all actions that are necessary, proper or advisable to comply promptly with all legal requirements with respect to the merger and the other transactions contemplated by the merger agreement, (2) obtain all permits, consents, authorizations, orders, clearances, waivers or approvals of any regulatory authority required or advisable in connection with the merger and the other transactions contemplated by the merger agreement and (3) resolve any objections that may be asserted by any governmental entity with respect to the merger agreement and the transactions contemplated thereby. However, in no event will S&T be required, or will DNB and its subsidiaries be permitted (without S&T’s prior written consent in its sole discretion), to take any action or agree to any condition or restriction involving S&T, DNB or any of their respective subsidiaries if such action, condition or restriction would have, or would be reasonably likely to have, individually or in the aggregate, a material adverse effect in respect of S&T and its subsidiaries, taken as a whole, or DNB and its subsidiaries, taken as a whole, in each case measured on a scale relative to DNB and its subsidiaries, taken as a whole. S&T and DNB have also agreed to furnish each other with all information reasonably necessary in connection with any statement, filing, notice or application in connection with the transactions contemplated by the merger agreement, except as set forth in the merger agreement, as well as to keep each other apprised of the status of matters related to the completion of the transactions contemplated by the merger agreement.

Tax Matters

S&T and DNB have agreed to use their respective reasonable best efforts to cause the merger to qualify as a “reorganization” within the meaning of Section 368(a) of the Code.

Employee Benefits Matters

For a period of one year following the closing date, S&T has agreed to provide to DNB employees (as a group) who are actively employed by DNB on the closing date and who continue to be actively employed by DNB following the effective time (which we refer to as the “covered employees”) with employee benefits and other compensatory or benefit plans, programs, policies or arrangements that are substantially comparable in the aggregate to those made available to similarly situated employees of S&T. Until such time as the covered

64

TABLE OF CONTENTS

employees commence participation in the S&T compensation and benefits programs, such employees’ continued participation in the DNB compensation and employee benefit plans will be deemed to satisfy the requirements of the foregoing covenant. Notwithstanding the foregoing, during the first year following the closing date, any covered employee who experiences a qualifying termination of employment and satisfies the applicable eligibility requirements shall be eligible for severance benefits in accordance with the terms of the severance guidelines or contract applicable to such employee as of immediately prior to the closing date. In addition, S&T has agreed to assume and honor all DNB benefit plans in accordance with their terms, except to the extent any DNB benefit plans are superseded or modified by any S&T plan, policy or agreement.

Additionally, with respect to any S&T employee compensation and benefits in which any covered employee becomes eligible to participate, S&T will recognize all service of covered employees with DNB for purposes of eligibility, participation and vesting under the S&T employee compensation and benefits to the same extent that such service was taken into account under the DNB plan prior to the effective time (except not for purposes of any incentive plan, retiree medical plan or defined benefit pension plan, for purposes of any plan that is intendedfrozen or that provides grandfathered benefits or to the extent such credit would result in a duplication of benefits). Additionally, with respect to any S&T health care plan in which any covered employee first becomes eligible to participate, S&T will use commercially reasonable efforts to: (i) waive all preexisting conditions or eligibility waiting periods, to the extent such limitations would have been waived or satisfied under the DNB health care plan in which such covered employee participated immediately prior to the effective time and (ii) provide credit for any health care expenses incurred by such covered employee in the year that includes the closing date of the merger (or, if later, the year in which the covered employee first becomes eligible to participate in such health care plan) for purposes of any deductibles and annual out-of-pocket expense requirements.

If requested by S&T in writing not less than 10 business days before the closing date, the board of directors of DNB will take steps to terminate DNB’s 401(k) plan, effective as of the day prior to the closing date but subject to the closing. If S&T requests that the DNB 401(k) plan be terminated, the assets of the DNB 401(k) plan will be distributed to participants following the effective time (and as soon as practicable following receipt of a favorable determination letter from the Internal Revenue Service (which we refer to as the “IRS”), if determined by S&T in its sole discretion to be appropriate). Following the effective time, to the extent permitted by S&T’s 401(k) plan, covered employees who are actively employed as of the date following receipt of the favorable determination letter from the IRS (if any) will be permitted to make eligible rollover contributions in the form of cash to the S&T 401(k) plan in an amount equal to the full account balance (excluding loans) distributed to such employee from the DNB 401(k) plan.

Between June 5, 2019 and the closing date of the merger, any written or oral communications to DNB employees, officers or directors pertaining to the merger or to compensation and benefits matters following the closing must be in the form of mutually agreeable communications prepared by DNB in prior consultation with S&T.

Director and Officer Indemnification and Insurance

The merger agreement provides that from and after the completion of the merger, the surviving corporation will indemnify and hold harmless all present and former directors, officers and employees of DNB or any of its subsidiaries (in each case, when acting in such capacity) against all liabilities arising out of the fact that such person is or was a director, officer or employee of DNB or any of its subsidiaries or is or was serving at the request of DNB or any of its subsidiaries as a director, officer, employee or agent of a corporation, partnership, joint venture, trust or other enterprise if the claim pertains to any matter arising, existing or occurring at or before the effective time of the merger (including any matter arising, existing or occurring in connection with the merger and the other transactions contemplated by the merger agreement), regardless of whether such claims are asserted before or after the effective time, to the fullest extent permitted by applicable law.

The merger agreement requires the surviving corporation to maintain, for a period of six years after completion of the merger, the currently existing directors’ and officers’ liability insurance policy maintained by DNB, or policies with a substantially comparable insurer of at least the same coverage and amounts and containing terms and conditions that are no less advantageous to the insured, with respect to claims arising from facts or events that occurred at or before the effective time of the merger, and covering such individuals who are currently covered by such insurance or who become covered by such insurance prior to the completion of the merger. However, the surviving corporation is not required to spend annually an amount more than 250% of the annual

65

TABLE OF CONTENTS

premium payment on DNB’s current directors’ and officers’ liability insurance policy. If the surviving corporation is unable to maintain a policy as described for less than that amount, the surviving corporation will obtain as much comparable insurance as is available for that amount. In lieu of such a policy, (1) S&T or the surviving corporation may substitute a six-year “tail” prepaid policy with terms no less favorable in any material respect to such directors and officers than DNB’s existing policy as of June 5, 2019 or (2) S&T may request that DNB obtain such “tail” prepaid coverage for the six-year period under DNB’s existing insurance programs. If S&T (or any of its successors or assigns) merges with another person and is not the continuing entity, or if S&T transfers or conveys all or substantially all of its properties or assets to another person, then S&T will ensure that its successors and assigns expressly assume S&T’s indemnification and insurance obligations.

Surviving Corporation Board of Directors; Governance Matters

Immediately following the effective time, S&T will appoint two members of the board of directors of DNB to the S&T board of directors. The two appointed members must be designated by the Nominating and Corporate Governance Committee of the S&T board of directors and must additionally satisfy and comply with applicable governmental and eligibility requirements for service on the S&T board of directors. Subject to the approval of the board of directors of S&T, the two appointed directors will be nominated for election at the next annual meeting of shareholders of S&T.

Surviving Corporation Officers

The officers of S&T in office immediately prior to the effective time, together with such additional persons as may thereafter be elected or appointed, shall serve as the officers of the surviving corporation from and after the effective time of the merger in accordance with the bylaws of S&T.

Restructuring Efforts

If DNB fails to receive shareholder approval to approve the merger agreement and the transactions contemplated by the merger agreement at its shareholder meeting, or any adjournment or postponement thereof, DNB will use its reasonable best efforts in good faith to negotiate a restructuring of the merger and/or resubmit the merger agreement or the restructured transactions to its shareholders for approval. In the case of a restructuring of the merger, DNB is not obligated to agree to alter or change any material term of the merger agreement, including the amount or kind of the merger consideration provided for in the merger agreement, or to enter into a restructuring of the transaction that adversely affects the tax treatment of the merger with respect to DNB shareholders.

Certain Policies

DNB has agreed that, prior to the effective time of the merger and to the extent permitted by law, it will modify and change its loan, investments, liquidity, litigation and real estate valuation policies and practices (including loan classifications and levels of reserves), in a manner consistent with GAAP and mutually satisfactory to DNB and S&T, so as to be applied on a basis consistent with that of S&T. However, DNB is not obligated to take any such action unless and until (1) S&T irrevocably acknowledges to DNB in writing that all conditions to its obligation to consummate the merger have been satisfied, (2) S&T irrevocably waives in writing any rights that it may have to terminate the merger agreement and (3) DNB has obtained shareholder approval of the merger agreement and the transactions contemplated by the merger agreement.

Certain Additional Covenants

The merger agreement also contains additional covenants, including covenants relating to the filing of this joint proxy statement/prospectus, obtaining required consents, the listing of the shares of S&T common stock to be issued in the merger, dividends of S&T and DNB to be declared after the date of the merger agreement, the redemption or assumption of DNB’s outstanding debt securities, trust preferred securities or related guarantees, access to information of the other company, notification of certain matters, exemption from takeover laws and public announcements with respect to the transactions contemplated by the merger agreement.

DNB Shareholder Meeting and Recommendation of the DNB Board of Directors

DNB has agreed to hold a meeting of its shareholders for the purpose of voting upon approval of the merger agreement and the transactions contemplated by the merger agreement as promptly as practicable. The DNB board of directors will solicit and use its reasonable best efforts to obtain from DNB shareholders the requisite shareholder approval of the merger agreement and the transactions contemplated by the merger agreement, including by recommending that DNB shareholders approve the merger agreement and the transactions contemplated by the merger agreement, subject to the DNB board of directors’ ability to make a change in company recommendation discussed below in “—Agreement Not to Solicit Other Offers.”

Agreement Not to Solicit Other Offers

For purposes of the merger agreement:

An “acquisition proposal” means any inquiries or the making of any proposal or offer with respect to, or a transaction to effect, a merger, reorganization, share exchange, consolidation, sale of assets, sale of shares of capital stock (including by way of a tender offer), business combination, recapitalization, liquidation, dissolution or similar transaction involving DNB or any of its subsidiaries, as applicable, that, if consummated, would constitute an “alternative transaction” (as described below);
An “alternative transaction” means any of (1) a transaction pursuant to which any person (or group of persons) other than S&T or its affiliates, directly or indirectly, acquires or would acquire more than 25% of the outstanding shares of DNB common stock or outstanding voting power of DNB, whether from DNB or pursuant to a tender offer or exchange offer or otherwise, (2) a merger, reorganization, share exchange, consolidation or other business combination involving DNB and any of its subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the fair market value of the consolidated assets of DNB (except, in each case, the merger or the bank merger), (3) any transaction pursuant to which any person (or group of persons) other than S&T or its affiliates, acquires or would acquire control of assets (including for this purpose, the outstanding equity securities of any DNB subsidiaries, and securities of the entity surviving any merger or business combination involving any DNB subsidiary) of DNB or any of its subsidiaries representing more than 25% of the fair market value of all the assets, deposits, net revenues or net income of DNB or any of its subsidiaries, taken as a whole, immediately prior to such transaction or (4) any other consolidation, business combination, recapitalization or similar transaction involving DNB or any of its subsidiaries, other than the transactions contemplated by the merger agreement, as a result of which the holders of shares of DNB common stock, immediately prior to such transaction do not, in the aggregate, own at least 75% of the outstanding shares of DNB common stock, and the outstanding voting power of the surviving or resulting entity in such transaction immediately following the completion of the transaction, in substantially the same proportion as such holders held the shares of DNB common stock, immediately prior to the completion of such transaction; and
A “superior proposal” for DNB means an unsolicited, bona fide written acquisition proposal made by a third person (or group of persons acting in concert) which the DNB board of directors has in good faith determined (taking into account the advice of its outside legal counsel and financial advisors and the terms of the acquisition proposal and the merger agreement) to be more favorable, from a financial point of view, to DNB shareholders than the transactions contemplated by the merger agreement (as may be proposed to be amended by S&T) and to be reasonably capable of being completed on the terms proposed, taking into account all other legal, financial, timing, regulatory and other aspects of such acquisition proposal and the person making the proposal. However, for purposes of the definition of “superior proposal,” the references to 25% in the definitions of “alternative transaction” and “acquisition proposal” are deemed to be references to 50%.

67

TABLE OF CONTENTS

DNB has agreed that it will not, and will cause each of its subsidiaries and its and their respective officers, directors, employees, agents and representatives not to, directly or indirectly:

initiate, solicit, knowingly encourage or knowingly facilitate any acquisition proposal;
participate in any discussions with or provide any nonpublic information to any person relating to an acquisition proposal or alternative transaction, engage in any negotiations concerning an acquisition proposal or alternative transaction, or knowingly facilitate any effort or attempt to make or implement an acquisition proposal or alternative transaction;
unless the merger agreement has been terminated in accordance with its terms, approve or execute or enter into any letter of intent, agreement in principle, merger agreement, asset purchase or share exchange agreement, option agreement or other contract (other than a confidentiality agreement entered into in compliance with the terms of the merger agreement) related to any acquisition proposal or alternative transaction; or
propose or agree to do any of the above.

However, the board of directors of DNB may, before the DNB shareholder approval is obtained, subject to compliance with its non-solicitation obligations (as described above) and to first entering into a confidentiality agreement having provisions that are no less favorable to DNB than those contained in the confidentiality agreement between S&T and DNB, engage in discussions and negotiations with, or provide any nonpublic information or data to, any person in response to an unsolicited bona fide written acquisition proposal by such person first made after the date of the merger agreement (which did not result from a breach of DNB’s non-solicitation obligations in the merger agreement) and which the DNB board of directors concludes in good faith (after consultation with its outside legal counsel and financial advisors) constitutes or is reasonably likely to result in (A)a superior proposal, if and only to the extent that the DNB board of directors concludes in good faith (after consultation with its outside legal counsel) that failure to do so would more likely than not result in a violation of the fiduciary duties under applicable law.

DNB has agreed to provide S&T prompt notice (and in no event later than 24 hours) after the receipt of any acquisition proposal, or any request for nonpublic information that may relate to an acquisition proposal, or any inquiry relating to a possible acquisition proposal. The notice will be made orally and in writing, and indicate the identity of the person making the acquisition proposal, inquiry or request and the material terms thereof (including a copy thereof if in writing and any related documentation or correspondence). DNB also agrees to provide S&T prompt notice (and in no event later than 24 hours) if it enters into any discussions or negotiations with or provides nonpublic information to a person as required by the directors’ fiduciary duties and permitted under the preceding paragraph. DNB will keep S&T informed of the status and terms of any such proposals, offers, inquiries, discussions or negotiations on a current basis, including by providing a copy of all material related documentation or correspondence.

Furthermore, none of DNB, the DNB board of directors or any of its committees will (1) withhold, withdraw or modify in any manner adverse to S&T (or propose publicly to do so) its recommendation of the merger agreement and the transactions contemplated by the merger agreement, (2) approve or recommend to its shareholders (or resolve to or publicly propose or announce its intention to do so) any acquisition proposal or (3) within 10 business days after an acquisition proposal is made public or any request by S&T, fail to publicly, finally and without qualification recommend against any acquisition proposal or reaffirm its recommendation for DNB shareholders to approve the merger agreement.

Notwithstanding the preceding paragraph, before the DNB shareholder approval is obtained, with respect to an acquisition proposal, the DNB board of directors may make a change in company recommendation if and only if (1) an unsolicited bona fide written acquisition proposal (which did not result from a breach of DNB’s non-solicitation obligations in the merger agreement) is made to DNB by a third party and not withdrawn, (2) the DNB board of directors concludes in good faith (in consultation with its outside legal counsel and financial advisors) that the acquisition proposal constitutes a superior proposal, (3) the DNB board of directors concludes in good faith (after consultation with its outside legal counsel) that failure to make a change in company recommendation would more likely than not result in a violation of the directors’ fiduciary duties under applicable law, (4) prior to effecting the change in company recommendation, DNB has given written notice to S&T advising S&T that it intends to effect a change in company recommendation, and three business days have

68

TABLE OF CONTENTS

elapsed, (5) during the three business day period, DNB has considered any adjustments or modifications to the merger agreement proposed by S&T and engaged in good faith discussions with S&T regarding such adjustments or modifications and (6) at the end of such period, the DNB board of directors again reasonably determines in good faith (after consultation with its outside legal counsel and its financial advisors, and taking into account any proposed adjustments or modifications to the merger agreement proposed by S&T) that the acquisition proposal continues to constitute a superior proposal and that failure to make a change in company recommendation would more likely than not result in a violation of the directors’ fiduciary duties under applicable law. In the event there is an amendment to any material term of the acquisition proposal, DNB is also required to notify S&T of the amendment and to consider any proposed adjustments or modifications to the merger agreement proposed by S&T, but the notification and proposal period will be two instead of three business days.

The merger agreement provides that nothing in the non-solicitation provisions of the merger agreement prohibits DNB or its subsidiaries from (1) taking and disclosing to its shareholders a position contemplated by Rule 14e-2(a) under the Exchange Act, (2) making a statement contemplated by Item 1012(a) of Regulation M-A or Rule 14d-9 under the Exchange Act or (3) issuing a “stop, look and listen” statement pending disclosure of its position under such rules. However, compliance with such rules will not eliminate or modify the effect that any action would otherwise have under the merger agreement. Any such disclosure (other than a “stop, look and listen” statement, which is followed within 10 business days by an unqualified public reaffirmation of the DNB board of directors’ recommendation of the merger agreement and the transactions contemplated by the merger agreement) constitutes a change in company recommendation, unless the DNB board of directors expressly publicly reaffirms, without qualification, its recommendation for the merger agreement in connection with such communication.

DNB has agreed to (1) cease immediately and terminate any and all existing activities, discussions or negotiations with any third parties with respect to any acquisition proposal or alternative transaction or similar transaction (and cause its respective subsidiaries and representatives to cease any such discussions) and (2) not release any third party from or waive the provisions of any confidentiality or standstill agreement to which DNB or its subsidiaries is a party with respect to any acquisition proposal or alternative transaction. DNB has agreed to promptly inform its and its subsidiaries’ representatives of these obligations not to solicit other offers.

S&T’s and DNB’s respective obligations to complete the merger are subject to the fulfillment or waiver of the following conditions:

the approval of the merger agreement and the transactions contemplated by the merger agreement by DNB’s shareholders;
the receipt of required regulatory approvals without a condition or restriction that would have, or would be reasonably likely to have, individually or in the aggregate, a material adverse effect on S&T and its subsidiaries, taken as a whole, or on DNB and its subsidiaries, taken as a whole (measured in each case on a scale relative to DNB and its subsidiaries, taken as a whole), and the expiration or termination of all related statutory waiting periods;
the absence of any order, injunction, decree or judgment by any governmental entity of competent jurisdiction or other legal restraint or prohibition preventing the completion of the merger, the bank merger or any of the other transactions contemplated by the merger agreement, and the absence of any law, order, injunction or decree that prohibits or makes illegal the completion of the merger, the bank merger or any of the other transactions contemplated by the merger agreement;
the authorization of the listing of the S&T common stock to be issued upon the consummation of the merger on the NASDAQ, without objection to the listing from NASDAQ;
the effectiveness of the registration statement of which this proxy statement/prospectus is a part with respect to the S&T common stock to be issued upon the consummation of the merger under the Exchange Act, and the absence of any stop order (or proceedings initiated or threatened by the SEC and continuing);
the readiness of S&T and DNB to consummate the bank merger immediately after the completion of the merger;

69

TABLE OF CONTENTS

the accuracy of the representations and warranties of each other party in the merger agreement as of the date of the merger agreement and as of the closing date as though made at and as of the closing date, subject to the materiality standards provided in the merger agreement (and the receipt by each party of certificates from the other party to such effect);
the performance by the other party in all material respects of all obligations required to be performed by it at or prior to the effective time of the merger under the merger agreement (and the receipt by each party of certificates from the other party to such effect); and
the receipt by each of S&T and DNB of an opinion of its respective legal counsel as to certain tax matters.

Neither DNB nor S&T can provide assurance as to when or if all of the conditions to the merger can or will be satisfied or waived by the appropriate party. As of the date of this proxy statement/prospectus, neither DNB nor S&T has reason to believe that any of these conditions will not be satisfied.

Termination of the Merger Agreement

The merger agreement can be terminated at any time prior to completion of the merger by mutual consent, or by either party in the following circumstances:

the merger has not been completed by the end date, but only if the failure to complete the merger by the end date is not caused by the terminating party’s breach of the merger agreement;
any required regulatory approval has been denied by the relevant regulatory authority and this denial has become final and non-appealable, or a regulatory authority has issued a final, non-appealable injunction or order permanently enjoining or otherwise prohibiting the completion of the merger or the other transactions contemplated by the merger agreement; or
there is a breach by the other party that, if continuing on the closing date, would cause the failure of certain of the closing conditions described above, and such breach is not cured prior to the earlier of the end date and 30 business days following written notice of the breach.

In addition, S&T may terminate the merger agreement under the following circumstances:

the DNB board of directors (1) fails to recommend to the DNB shareholders that they approve the merger agreement and the transactions contemplated by the merger agreement or (2) effects a change in company recommendation with respect to the merger agreement or the transactions contemplated thereby; or
the DNB board of directors fails to comply in any material respect with its non-solicitation obligations described in “—Agreement Not to Solicit Other Offers” or its obligations with respect to calling a shareholder meeting described in “—DNB Shareholder Meeting and Recommendation of the DNB Board of Directors.

In addition, DNB may terminate the merger agreement at any time during the five-day period commencing with the determination date, if both of the following conditions are satisfied:

the average closing price of S&T common stock as reported on NASDAQ for the 20 consecutive trading days ending on the trading day prior to the determination date is less than 75% of the closing price of S&T common stock on the last trading day immediately before the public announcement of the merger agreement; and
S&T common stock underperforms the S&P 600 Bank Index by more than 25% during the same period, as determined by dividing the average closing prices of S&T common stock and the S&P 600 Bank Index, as applicable, for the 20 consecutive trading days ending on the trading day prior to the determination date by the closing price of S&T common stock and the S&P 600 Bank Index, as applicable, on the last trading day immediately before the public announcement of the merger agreement.

TABLE OF CONTENTS

Effect of Termination

If the merger agreement is terminated, it will become void, except that (1) both S&T and DNB will remain liable for any fraud or willful and material breach of the merger agreement and (2) designated provisions of the merger agreement will survive the termination, including those relating to payment of fees and expenses and the confidential treatment of information.

Termination Fee

DNB will pay to S&T an $8 million termination fee if the merger agreement is terminated in the following circumstances:

Amendment, Waiver and Extension of the Merger Agreement

Subject to applicable law, S&T and DNB may amend the merger agreement by written agreement. However, after any approval of the merger agreement and the transactions contemplated by the merger agreement by DNB shareholders, there may not be, without further approval of DNB shareholders, any amendment of the merger agreement that requires further approval under applicable law.

At any time prior to the effective time of the merger, each party, to the extent legally allowed, may extend the time for the performance of any of the obligations or other acts of the other party; waive any inaccuracies in the representations and warranties of the other party; and waive compliance by the other party with any of the agreements and conditions for its benefit contained in the merger agreement.

Voting Agreements

The directors and certain executive officers of DNB have each entered into voting agreements with S&T, solely in their capacities as shareholders of DNB, pursuant to which they have agreed, among other things, to vote in favor of the DNB merger proposal and the other proposals presented at the DNB special meeting and against any alternative acquisition proposal, as well as certain other customary restrictions with respect to the voting and transfer of his or her shares of DNB common stock.

The preceding discussion is a summary of the voting agreements and is qualified in its entirety by reference to the form of voting agreement, which is provided in its entirety as Annex C to this proxy statement/prospectus.

TABLE OF CONTENTS

ACCOUNTING TREATMENT

The accounting principles applicable to this transaction are included in the FASB Codification Topic ASC 805, Business Combinations. ASC 805 provides guidance on the accounting and reporting of transactions that represent business combinations to be accounted for under the acquisition method. The acquisition method entails: (a) identification of the acquirer; (b) determination of the acquisition date; (c) recognition and measurement of the identifiable assets acquired, the liabilities assumed, and any non-controlling interest in the acquiree; and (d) recognition and measurement of goodwill or a gain from a bargain purchase.

In this transaction S&T is the acquirer and will accordingly apply the acquisition method of accounting to the business combination. On the acquisition date, S&T (the acquirer) will recognize and measure, at fair value, all of the identifiable assets acquired and liabilities assumed. S&T will also recognize goodwill arising from the transaction. The results of operations for the combined company will be reported prospectively subsequent to the acquisition date.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

This section describes the material U.S. federal income tax consequences of the merger to “U.S. holders” (as defined below) of DNB common stock that exchange their shares of DNB common stock for shares of S&T common stock in the merger. The following discussion is based upon the Code, the U.S. Treasury regulations promulgated thereunder and judicial and administrative authorities, rulings and decisions, all as in effect as of the date of this proxy statement/prospectus. These authorities may change, possibly with retroactive effect, and any such change could affect the accuracy of the statements and conclusions set forth in this discussion. This discussion does not address any tax consequences arising under the unearned income Medicare contribution tax pursuant to the Health Care and Education Reconciliation Act of 2010, nor does it address any tax consequences arising under the laws of any state, local or foreign jurisdiction, or under any U.S. federal laws other than those pertaining to the income tax.

The following discussion applies only to U.S. holders of shares of DNB common stock who hold such shares as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment). Further, this discussion does not purport to consider all aspects of U.S. federal income taxation that might be relevant to U.S. holders in light of their particular circumstances and does not apply to U.S. holders subject to special treatment under the U.S. federal income tax laws (such as, for example, dealers or brokers in securities, commodities or foreign currencies, traders in securities that elect to apply a mark-to-market method of accounting, banks and certain other financial institutions, insurance companies, mutual funds, tax-exempt organizations, holders subject to the alternative minimum tax provisions of the Code, partnerships, S corporations or other pass-through entities or investors therein, regulated investment companies, real estate investment trusts, controlled foreign corporations, passive foreign investment companies, former citizens or residents of the United States, U.S. expatriates, holders whose functional currency is not the U.S. dollar, holders who hold shares of DNB common stock as part of a hedge, straddle, constructive sale or conversion transaction or other integrated investment, retirement plan, individual retirement account, or other tax-deferred accounts, holders who acquired DNB common stock pursuant to the exercise of employee stock options, through a tax-qualified retirement plan or otherwise as compensation or holders who actually or constructively own more than 5% of DNB common stock).

For purposes of this discussion, the term “U.S. holder” means a beneficial owner of DNB common stock that is for U.S. federal income tax purposes (1) an individual citizen or resident of the United States, (2) a corporation, or entity treated as a corporation for U.S. federal income tax purposes, organized in or under the laws of the United States or any state thereof or the District of Columbia, (3) a trust if (a) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) such trust has a valid election in effect to be treated as a U.S. person for U.S. federal income tax purposes or (4) an estate, the income of which is subject to U.S. federal income tax, regardless of its source.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds DNB common stock, the tax treatment of a partner in such partnership generally will depend on the status of the partner and the activities of the partnership. Any entity treated as a partnership for U.S. federal income tax purposes that holds DNB common stock, and any partners in such partnership, should consult their own independent tax advisors regarding the tax consequences of the merger to their specific circumstances.

Determining the actual tax consequences of the merger to you may be complex and will depend on your specific situation and on factors that are not within our control. You should consult your own independent tax advisor as to the specific tax consequences of the merger in your particular circumstances, including the applicability and effect of the alternative minimum tax and any state, local, foreign and other tax laws and of changes in those laws.

Tax Consequences of the Merger Generally

It is a condition to the obligation of S&T to complete the merger that S&T receive an opinion from Wachtell, Lipton, Rosen & Katz, dated the closing date of the merger, to the effect that the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. It is a condition to the obligation of DNB to complete the merger that DNB receive an opinion from Stradley Ronon Stevens & Young, LLP dated the closing date of the merger, to the effect that the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. These opinions will be based on facts and representations contained in representation

73

TABLE OF CONTENTS

letters provided by S&T and DNB and on customary factual assumptions. Neither of the opinions described above will be binding on the IRS or any court. S&T and DNB have not sought and will not seek any ruling from the IRS regarding any matters relating to the merger, and as a result, there can be no assurance that the IRS will not assert, or that a court would not sustain, a position contrary to any of the conclusions set forth below. In addition, if any of the representations or assumptions upon which those opinions are based are inconsistent with the actual facts, the U.S. federal income tax consequences of the merger could be adversely affected.

Accordingly, upon exchanging your DNB common stock for S&T common stock, you generally will not recognize gain or loss, except with respect to cash received instead of fractional shares of S&T common stock (as discussed below). The aggregate tax basis of the S&T common stock that you receive in the merger (including any fractional shares deemed received and redeemed for cash as described below) will equal your aggregate adjusted tax basis in the shares of DNB common stock you surrender in the merger. Your holding period for the shares of S&T common stock that you receive in the merger (including any fractional share deemed received and redeemed for cash as described below) will include your holding period of the shares of DNB common stock that you surrender in the merger. If you acquired different blocks of DNB common stock at different times or at different prices, the S&T common stock you receive will be allocated pro rata to each block of DNB common stock, and the basis and holding period of each block of S&T common stock you receive will be determined on a block-for-block basis depending on the basis and holding period of the blocks of DNB common stock exchanged for such blocks of S&T common stock.

Cash Instead of Fractional Shares

If you receive cash instead of a fractional share of S&T common stock, you will be treated as having received such fractional share of S&T common stock pursuant to the merger and then as having sold such fractional share of S&T common stock for cash. As a result, you generally will recognize gain or loss equal to the difference between the amount of cash received and the basis in your fractional share of S&T common stock as set forth above. Such gain or loss generally will be capital gain or loss and will be long-term capital gain or loss if, as of the effective date of the merger, the holding period for such fractional share (including the holding period of shares of DNB common stock surrendered therefor) exceeds one year. Long-term capital gains of individuals are generally eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations.

Information Reporting and Backup Withholding

If you are a non-corporate holder of DNB common stock, you may be subject, under certain circumstances, to information reporting and backup withholding (currently at a rate of 24%) on any cash payments you receive. You generally will not be subject to backup withholding, however, if you (1) furnish a correct taxpayer identification number, certify that you are not subject to backup withholding and otherwise comply with all the applicable requirements of the backup withholding rules; or (2) provide proof that you are otherwise exempt from backup withholding. Any amounts withheld under the backup withholding rules are not an additional tax and will generally be allowed as a refund or credit against your U.S. federal income tax liability, provided you timely furnish the required information to the IRS.

This discussion of certain material U.S. federal income tax consequences is not intended to be, and should not be construed as, tax advice. Holders of DNB common stock are urged to consult their independent tax advisors with respect to the application of U.S. federal income tax laws to their particular situations as well as any tax consequences arising under the U.S. federal estate or gift tax rules, or under the laws of any state, local, foreign or other taxing jurisdiction or under any applicable tax treaty.

TABLE OF CONTENTS

DESCRIPTION OF CAPITAL STOCK OF S&T

As a result of the merger, DNB shareholders who receive shares of S&T common stock in the merger will become shareholders of S&T. Your rights as shareholders of S&T will be governed by Pennsylvania law and the articles of incorporation and the bylaws of S&T, each as amended to date. The following briefly summarizes the material terms of S&T common stock. We urge you to read the applicable provisions of the PBCL, S&T’s articles of incorporation and bylaws and federal laws governing bank holding companies carefully and in their entirety. Copies of S&T’s and DNB’s governing documents have been filed with the SEC. To find out where copies of these documents can be obtained, see “Where You Can Find More Information.”

Authorized Capital Stock

S&T’s authorized capital stock consists of 50 million shares of common stock, par value $2.50 per share, and 10 million shares of preferred stock, without par value. As of the record date, there were [      ] shares of S&T common stock outstanding and [      ] shares of S&T preferred stock outstanding.

Common Stock

Dividend Rights

S&T can pay dividends if, as and when declared by the S&T board of directors, subject to compliance with limitations imposed by law. The holders of S&T common stock will be entitled to receive and share equally in these dividends as they may be declared by the S&T board of directors out of funds legally available for such purpose. If S&T issues preferred stock, the holders of such preferred stock may have a priority over the holders of the common stock with respect to dividends.

Voting Rights

Each holder of S&T common stock will be entitled to one vote per share and will not have any right to cumulate votes in the election of directors. Directors will be elected by a plurality of the votes cast at each annual meeting or special meeting called for the purpose of electing such directors. If S&T issues preferred stock, holders of the preferred stock may also possess voting rights.

Liquidation Rights

In the event of liquidation, dissolution or winding-up of S&T, whether voluntary or involuntary, the holders of S&T common stock would be entitled to receive, after payment or provision for payment of all its debts and liabilities, all of the assets of S&T available for distribution. If preferred stock is issued, the holders thereof may have a priority over the holders of the common stock in the event of liquidation or dissolution.

Preemptive Rights

Holders of the common stock of S&T will not be entitled to preemptive rights with respect to any shares which may be issued. Preemptive rights are the priority rights to buy additional shares if S&T issues more shares in the future. Therefore, if additional shares are issued by S&T without the opportunity for existing shareholders to purchase more shares, a shareholder’s ownership interest in S&T may be subject to dilution.

For more information regarding the rights of holders of S&T common stock, see “Comparison of Shareholders’ Rights.”

Preferred Stock

S&T’s articles of incorporation, as amended to date, permit the S&T board of directors to issue up to 10 million shares of preferred stock, no par value, in one or more series, with such designations, voting powers, and such rights, preferences and limitations as may be fixed by the S&T board of directors without any further action by S&T shareholders. The issuance of preferred stock could adversely affect the rights of holders of common stock.

TABLE OF CONTENTS

COMPARISON OF SHAREHOLDERS’ RIGHTS

S&T is incorporated under the laws of the Commonwealth of Pennsylvania, and, accordingly, the rights of S&T shareholders are governed by Pennsylvania law and S&T’s organizational documents. DNB is also incorporated under the laws of the Commonwealth of Pennsylvania, and, accordingly, the rights of DNB shareholders are governed by Pennsylvania law and DNB’s organizational documents. Consequently, after the effective time of the merger, the rights of former DNB shareholders who receive S&T common stock as merger consideration will be governed by Pennsylvania law and determined by reference to S&T’s organizational documents.

The following is a summary of certain material differences between (1) the current rights of DNB shareholders under DNB’s articles of incorporation and bylaws, each as amended to date, and Pennsylvania law, including the PBCL and (2) the current rights of S&T shareholders under S&T’s articles of incorporation and bylaws, each as amended to date, and Pennsylvania law, including the PBCL, which will govern the rights of DNB shareholders who become S&T shareholders following the merger.

The following summary is not a complete statement of the rights of shareholders of the two companies or a complete description of the specific provisions referred to below. This summary is qualified in its entirety by reference to S&T’s and DNB’s respective governing documents and the provisions of the PBCL, which we urge you to read carefully and in their entirety. Copies of the respective companies’ governing documents have been filed with the SEC. To find out where copies of these documents can be obtained, see “Where You Can Find More Information.”

Authorized Capital Stock

S&T

S&T’s articles of incorporation, as amended to date, authorize it to issue up to 60 million shares, consisting of 50 million shares of common stock, par value $2.50 per share, and 10 million shares of preferred stock, without par value. As of the record date, there were [      ] shares of S&T common stock outstanding and no shares of S&T preferred stock outstanding. The S&T board of directors is authorized to issue the preferred stock in one or more series.

DNB

DNB’s amended and restated articles of incorporation authorize DNB to issue up to 10,000,000 shares of common stock, par value $1.00 per share, and up to 1,000,000 shares of preferred stock, par value $10.00 per share. As of the record date for the DNB special meeting, there were [   ] shares of DNB common stock issued and outstanding and no shares of DNB preferred stock issued and outstanding. As of the record date, there were [   ] shares of DNB common stock held by DNB as treasury stock. DNB’s board of directors has the authority, without further action by DNB shareholders, to divide any authorized class of preferred stock into series, and to fix and determine the relative rights and preferences of the shares of any series of preferred stock so established.

Pennsylvania Anti-Takeover Provisions

Under the PBCL, certain anti-takeover provisions apply to Pennsylvania “registered corporations” (e.g., publicly traded companies) including those relating to (1) control share acquisitions, (2) disgorgement of profits by certain controlling persons, (3) business combination transactions with interested shareholders and (4) the rights of shareholders to demand fair value for their stock following a control transaction. Pennsylvania law allows registered corporations to opt out of any of these anti-takeover provisions. S&T is a registered corporation under the PBCL and has opted out of the anti-takeover provisions listed in (1) and (2) above. DNB is a registered corporation under the PBCL and has opted out of the anti-takeover provisions listed in (1) and (2) above.

Control Share Acquisitions

Pennsylvania law limits control share acquisitions relating to the act of acquiring for the first time voting power over voting shares (other than shares owned since January 1, 1988 and any additional shares distributed with respect to such shares) equal to at least 20%, 33 1/3% and 50% or more of the voting power of the corporation. Once a control share acquisition has occurred, all shares in excess of the triggering threshold, plus shares purchased at any time with the intention of acquiring such voting power and shares purchased within 180 days of

76

TABLE OF CONTENTS

the date on which the triggering threshold was exceeded, are considered control shares. Control shares cannot vote until their voting rights have been restored by two separate votes of the shareholders at a meeting or until such shares are transferred to a person who does not thereby also become the holder of control shares.

The holder of control shares may wait until the next annual or special meeting after the acquisition had taken place to submit the request for the restoration of voting rights to the shareholders, or the acquiring person may accelerate the process by agreeing to underwrite the cost of a special meeting of shareholders for that purpose. In either case, the acquiring person is required to furnish for distribution to the shareholders an information statement containing a detailed disclosure concerning the acquiring person, its intentions with respect to ownership of securities of the corporation and other matters. As an alternative, a person proposing to make a control share acquisition may request prospective approval by the shareholders of the exercise of the voting rights of the shares proposed to be acquired. Two shareholders’ votes are required to approve the restoration of voting rights: (1) the approval of an absolute majority of all voting power must be obtained, and all voting shares are entitled to participate in this vote; and (2) the approval of an absolute majority of all disinterested shareholders must be obtained.

For a period of 24 months after the later of (1) a control share acquisition by an acquiring person who does not properly request consideration of voting rights, or (2) the denial of such a request or lapse of voting rights, the corporation may redeem all the control shares at the average public market sales price of the shares on the date on which notice of the call for redemption is given by the corporation.

Disgorgement of Profits by Certain Controlling Persons

Pennsylvania law regarding disgorgement of profits by certain controlling persons applies in the event that (1) any person or group publicly discloses that the person or group may acquire control of the corporation, or (2) a person or group acquires (or publicly discloses an intent to acquire) 20% or more of the voting power of the corporation and, in either case, sells shares within 18 months thereafter. Any profits from sales of equity securities of the corporation received by the person or group during such 18-month period will belong to the corporation if the securities that were sold were acquired during the 18-month period or within 24 months prior thereto.

Business Combination Transactions with Interested Shareholders

Pennsylvania law prohibits certain business combinations with certain “interested shareholders,” persons who acquire the direct or indirect beneficial ownership of shares entitled to cast at least 20% of the votes entitled to be cast for the election of directors. A corporation subject to this provision may not effect mergers or certain other business combinations with the interested shareholder for a period of five years, unless (1) the business combination or the acquisition of stock by means of which the interested shareholder became an interested shareholder is approved by the corporation’s board of directors prior to such stock acquisition; (2) the business combination is approved by the affirmative vote of the holders of all the outstanding common shares of the corporation; or (3) the business combination is approved by the affirmative vote of the holders of a majority of all shares entitled to vote, excluding votes of shares held by the interested shareholders, and at the time of such vote, the interested shareholder is the beneficial owner of at least 80% of the voting shares of the corporation. This exception applies only if the value of the consideration to be paid by the interested shareholder in connection with the business combination satisfies certain fair price requirements.

After the five-year restricted period, an interested shareholder of the corporation may engage in a business combination with the corporation if (1) the business combination is approved by the affirmative vote of a majority of the shares other than those beneficially owned by the interested shareholder and its affiliates, or (2) the merger is approved at a shareholders’ meeting and certain fair price requirements are met.

Rights of Shareholders to Demand Fair Value for Stock Following a Control Transaction

Pennsylvania law regarding the ability of shareholders to dispose of their stock following a control transaction provides, generally, that a person or group that acquires more than 20% of the voting power to elect directors of the corporation is a controlling person and must give prompt notice to each shareholder of record. The other shareholders are then entitled to demand that the controlling person pay them the fair value of their shares under specified procedures. Fair value may not be less than the highest price paid per share by the controlling person at any time during the 90-day period ending on and including the date on which the controlling person became such, plus any increment representing any value, such as a control premium, that is not reflected in such price.

Size of Board of Directors

S&T

S&T’s bylaws, as amended to date, currently provide that the S&T board of directors shall consist of a minimum of nine and a maximum of 17 directors, and that the size of the board may be determined from time to time by resolution of the board.

Cumulative Voting and Election of Directors

S&T

S&T shareholders do not have the right to cumulate their votes with respect to the election of directors. To be elected, each director nominee must receive a plurality of votes cast by S&T common shareholders at each annual meeting of the shareholders, or a similar vote at any special meeting called for the purpose of electing directors. Members of the S&T board of directors are elected annually to a one-year term.

DNB

DNB’s amended and restated articles of incorporation provide that DNB shareholders shall not be permitted to cumulate their votes with respect to the election of directors. DNB’s board of directors is classified. DNB’s amended and restated bylaws, as amended, provide that the board shall be divided into three classes, with directors in each of the classes to hold office for three-year terms. The classes are staggered such that one class of directors stands for election each year. To be elected, each director nominee must receive a plurality of votes cast by DNB common shareholders at each annual meeting of the shareholders, or a similar vote at any special meeting called for the purpose of electing directors.

Removal of Directors

S&T

Under Pennsylvania law, directors may be removed, with or without cause, by the affirmative vote of holders of a majority of the shares entitled to vote on such matter. Because S&T’s articles of incorporation and bylaws, each as amended to date, do not provide otherwise, the default Pennsylvania statute applies to the removal of S&T directors.

DNB

Under Pennsylvania law, directors may be removed, with or without cause, by the affirmative vote of holders of a majority of the shares entitled to vote on such matter. Because DNB’s amended and restated articles of incorporation and amended and restated bylaws, as amended, do not provide otherwise, the default Pennsylvania statute applies to the removal of DNB directors.

Filling Vacancies on the Board of Directors

S&T

S&T’s bylaws, as amended to date, provide that if a vacancy occurs on the S&T board of directors, including a vacancy resulting from an increase in the number of directors, the board of directors may fill the vacancy, or, if the directors in office constitute fewer than a quorum of the board of directors, they may fill the vacancy by the affirmative vote of a majority of all the directors in office. The shareholders may fill a vacancy only if there are no directors in office. The term of any director elected to fill a vacancy shall expire at the next election of directors by the shareholders.

78

TABLE OF CONTENTS

DNB

DNB’s amended and restated bylaws, as amended, provide that vacancies on the board of directors, including vacancies resulting from an increase in the number of directors, may be filled by a majority of the directors then remaining in office, whether or not a quorum exists.

Special Meetings of Shareholders

S&T

Under S&T’s bylaws, as amended to date, special meetings of the shareholders may be called at any time by the board of directors, the chief executive officer, or by the holders of at least 20% of all S&T common shares entitled to vote at such meeting. Only those matters specified in the written notice of the special meeting may be conducted at the meeting.

DNB

Under DNB’s amended and restated bylaws, as amended, a special meeting may be called by the chairperson of the board of directors, the president, the chief executive officer, a majority of the board of directors or a majority of the executive committee of the board of directors. Under the PBCL, shareholders of a registered corporation are not entitled by statute to call a special meeting of shareholders and neither DNB’s amended and restated articles of incorporation nor its amended and restated bylaws, as amended, permit shareholders to call a special meeting.

Quorum

S&T

Under Pennsylvania law, the presence at meetings, in person or represented by proxy, of the holders of the majority of the outstanding shares of S&T common stock entitled to vote at the meeting constitutes a quorum for the transaction of business at the meeting of shareholders.

DNB

Under Pennsylvania law, the presence at meetings, in person or represented by proxy, of the holders of the majority of the outstanding shares of DNB common stock entitled to vote at the meeting constitutes a quorum for the transaction of business at the meeting of shareholders.

Dividends

S&T

Under Pennsylvania law, S&T may not declare a dividend if, after giving effect to such dividend, it would not be able to pay its debts as they become due in the usual course of business or if its total assets would be less than the sum of its total liabilities plus the amount that would be needed, if the corporation were to be dissolved at the time as of which the dividend is measured, to satisfy the preferential rights upon dissolution of shareholders whose preferential rights are superior to those receiving the dividends. In addition, the Federal Reserve Board has the authority to restrict dividends issued by bank holding companies, including S&T.

DNB

Under Pennsylvania law, DNB may not declare a dividend if, after giving effect to such dividend, it would not be able to pay its debts as they become due in the usual course of business or if its total assets would be less than the sum of its total liabilities plus the amount that would be needed, if the corporation were to be dissolved at the time as of which the dividend is measured, to satisfy the preferential rights upon dissolution of shareholders whose preferential rights are superior to those receiving the dividends.

Notice of Shareholder Meetings

S&T

S&T’s bylaws, as amended to date, provide that S&T must give written notice of a shareholder meeting to each shareholder of record entitled to vote at such meeting at least five days prior to the meeting date.

Indemnification of Directors and Officers and Insurance

S&T

S&T’s bylaws, as amended to date, provide for the indemnification of current and former directors and officers to the fullest extent authorized by the laws of the Commonwealth of Pennsylvania. In particular, the S&T bylaws, as amended, indemnify directors and officers against all expense, liability and loss reasonably suffered in their capacity as director or officer so long as such person acted in acted in good faith and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. If requested, S&T must advance the expenses incurred by a director or officer in defending claims in advance of its final disposition, provided that such indemnified director or officer must provide an undertaking to repay the advance if it is ultimately determined by a final judicial decision that such person is not entitled to indemnification.

S&T’s bylaws, as amended to date, provide that S&T may maintain insurance, at its expense to protect itself and any director, officer, employee or agent of S&T or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not S&T would have the power to indemnify such person against any such expense, liability or loss under the Commonwealth of Pennsylvania.

DNB

DNB’s amended and restated bylaws provide that DNB shall indemnify any director, officer and/or employee, or any former officer and/or employee, who was or is a party to, or is threatened to be made a party to, or who is called to be a witness in connection with, any threatened pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative by reason of the fact that such person is or was an officer and/or employee of DNB, or is or was serving at the request of DNB as a director, officer, employee or agent of a corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action, suit or proceeding if he or she acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of DNB, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, shall not of itself create a presumption that the person did not act in good faith and in a manner which he or she reasonably believed to be in, or not opposed to, the best interests of DNB, and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was unlawful. If the indemnification is for an action by or in the right of DNB, the indemnification shall not be made if such person shall have been adjudged to be liable for misconduct in the performance of his or her duty to DNB. The indemnification provisions also permit DNB to pay expenses to a director, officer and/or employee in defending a civil or criminal action, suit or proceeding, provided that the indemnified person undertakes to repay DNB if it is ultimately determined that such person was not entitled to be indemnified by DNB.

Amendments to Articles of Incorporation and Bylaws

S&T

Pennsylvania law provides that shareholders of a registered corporation, such as S&T, are not entitled by statute to propose amendments to the articles of incorporation.

Under Pennsylvania law, an amendment to the articles of incorporation requires the approval of the board of directors and, except in certain instances where a greater vote may be required, the affirmative vote of a majority of the vote cast by all shareholders entitled to vote on the matter (and the affirmative vote of a majority of the votes cast by all shareholders within each class or series if such class or series is entitled vote on the matter as a class).

S&T’s articles of incorporation may be amended as provided under Pennsylvania law, with the following exception: any amendment to Article 12 (Shareholder Action) requires the affirmative vote of holders of at least two-thirds of the votes that all shareholders are entitled to cast thereon at a regular or special meeting. S&T’s bylaws may be amended or repealed by a majority vote of the board of directors at any duly convened meeting of the board.

DNB

The PBCL provides that a company’s articles of incorporation may be amended by a majority vote of the votes cast by all shareholders entitled to vote on such matter, unless the articles of incorporation require a greater vote. Section 6 of DNB’s amended and restated articles of incorporation, relating to the shareholder vote required to approve mergers and similar transactions under certain circumstances, provides that such section may only be amended by the affirmative vote of the holders of at least 75% of the outstanding shares of DNB’s common stock. This provision does not apply to any particular transaction, and such transaction shall require only such affirmative vote as is required by any other provision of DNB’s amended and restated articles of incorporation or any provision of law, if the transaction shall have been approved by a two-thirds vote of the board of directors of DNB.

Action by Written Consent of the Shareholders

S&T

Under Pennsylvania law, shareholders may act without a shareholder meeting by unanimous written consent.

DNB

Under Pennsylvania law, shareholders may act without a shareholder meeting by unanimous written consent.

Shareholder Rights Plan

Neither S&T nor DNB currently has a shareholder rights plan in effect.

Required Vote for Certain Business Combinations

S&T

Any plan or proposal for the merger, consolidation, liquidation or dissolution of S&T or any action that would result in the sale or other disposition of all or substantially all of the assets of S&T, will require the affirmative vote of the holders of at least 66 2/3% of the outstanding shares of common stock.

DNB

Any plan or proposal for the merger, consolidation, liquidation or dissolution of DNB or any action that would result in the sale or other disposition of all or substantially all of the assets of DNB, will require the affirmative vote of the holders of at least seventy-five percent (75%) of the outstanding shares of common stock. The foregoing sentence shall not, however, apply to any particular transaction, and such transaction shall require only such affirmative vote of the holders of at least a majority of the outstanding shares of common stock, if the transaction shall have been approved by a two-thirds vote of the board of directors.

DEADLINES FOR SUBMITTING DNB SHAREHOLDER PROPOSALS

If the merger is completed as currently anticipated, DNB does not expect to hold an annual meeting of shareholders in 2020. However, if the merger is not completed as anticipated, DNB may hold a 2020 annual meeting of shareholders.

DNB shareholders who wish to present a proposal for consideration at DNB’s 2020 annual meeting and want the proposal to be included in DNB’s proxy statement and form of proxy card for that meeting, must send written notice of the proposal to DNB’s Corporate Secretary so that it is received at DNB’s principal executive offices no later than November 23, 2019, which is the month and day that is 120 calendar days before the one-year anniversary of the date that DNB first sent the proxy statement for its 2019 annual meeting of shareholders to DNB shareholders. The proposal must comply with the requirements of SEC Rule 14a-8, and DNB can exclude a proposal in the types of cases described in Rule 14a-8.

Whether or not a DNB shareholder wants DNB to include a proposal in DNB’s proxy statement, DNB’s amended and restated bylaws, as amended, require that, if a shareholder wants a proposal to be eligible for consideration at DNB’s 2020 annual meeting, the shareholder must give written notice of the proposal to DNB’s Corporate Secretary no later than January 23, 2020 (ninety days before April 22, 2020, the scheduled date of DNB’s 2020 annual meeting), including: (a) a brief description of the proposal, why the shareholder is presenting it and why it should be adopted; (b) the shareholder’s name and address as they appear in DNB’s shareholder records; (c) the class and number of DNB shares owned by the shareholder, including shares held in the shareholder’s name or beneficially in another name; and (d) any material interest the shareholder has in connection with the proposal or its adoption.

The chairperson of the meeting may determine whether a proposal was made in accordance with this required procedure. If the chairperson decides that the proposal was not made in accordance with this procedure, the chairperson will state that to the meeting and the defective proposal will be disregarded and laid over for action at the next shareholder meeting that is held at least 30 days after the meeting where the proposal was rejected for this reason.

If a shareholder proposal is presented to the 2020 annual meeting, DNB’s proxy holders will be authorized by DNB’s form of proxy to vote for or against the proposal, in their discretion, if DNB does not receive notice of the proposal, addressed to the Corporate Secretary at DNB’s principal executive offices, prior to the close of business on February 06, 2020, which is the date in 2020 that is the month and day that is 45 days before the one-year anniversary of the date that DNB first sent the proxy statement for the 2019 annual meeting of shareholders to DNB shareholders. Pursuant to SEC Rule 14a-4(c) (2), if DNB receives timely notice of a proposal, DNB’s proxy holders may still exercise discretion to vote on a matter if permitted by that rule and if DNB includes it in DNB’s proxy statement for the meeting, a description of the matter and how the DNB proxies intend to exercise their discretion to vote on the matter.

If a DNB shareholder wants to nominate a candidate for election as a director, the shareholder must notify DNB’s Corporate Secretary in writing no later than January 23, 2020, which is ninety days before April 22, 2020, the scheduled date of DNB’s 2020 annual meeting. If the shareholder wants the Nominating & Corporate Governance Committee of DNB’s board of directors to fully consider the shareholder’s nominee and to consider whether the Nominating & Corporate Governance Committee should nominate the nominee, the shareholder must notify DNB no later than November 23, 2019. The notification must contain the following information to the extent known by the shareholder: (a) the proposed nominee’s name and address; (b) the proposed nominee’s age; (c) the proposed nominee’s principal occupation; (d) the number of DNB shares the proposed nominee owns; (e) the total number of shares the shareholder expects to be voted for the proposed nominee; (f) the shareholder’s name and residence address; and (g) the number of DNB shares owned by the shareholder.

If a nomination made by a shareholder is not made according to these procedures, DNB’s amended and restated bylaws, as amended, require the nomination to be disregarded by the presiding officer of the meeting, and votes cast for the nominee will be disregarded by the judges of election.

2.2   Delivery of Merger Consideration.

(a)   As soon as reasonably practicable after the Effective Time, the Exchange Agent shall mail to each holder of record immediately prior to the Effective Time (each, a “Holder,” and collectively, “Holders”) of certificates representing shares of Company Common Stock (each, a “Certificate”) and uncertificated shares of Common Company Stock represented by book-entry form (“Book-Entry Shares”) that have been converted into the right to receive the Merger Consideration pursuant to Section 1.8, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to Certificate(s) or Book-Entry Share(s) shall pass only upon delivery of Certificate(s) (or affidavits of loss in lieu of such Certificate(s)) or transfer of such Book-Entry Share(s) to the Exchange Agent and shall be substantially in such form and have such other provisions as shall be prescribed by the Exchange Agent and Parent) (the “Letter of Transmittal”) and (ii) instructions for use in surrendering Certificate(s) or Book-Entry Share(s) in exchange for the Merger Consideration and any cash in lieu of a fractional share and any dividends or distributions to which such Holder is entitled pursuant to Section 2.2(c).

(b)   Upon proper surrender to the Exchange Agent of its Certificate(s) or transfer of its Book-Entry Share(s), accompanied by a properly completed Letter of Transmittal, a Holder of Company Common Stock shall be entitled to receive, promptly after the Effective Time, the Merger Consideration in respect of the

A-3

TABLE OF CONTENTS

shares of Company Common Stock represented by its Certificate(s) or Book-Entry Share(s), as applicable. Until so surrendered, each such Certificate or Book-Entry Share shall represent after the Effective Time, for all purposes, only the right to receive, without interest, the applicable Merger Consideration upon surrender of such Certificate or Book-Entry Share in accordance with this Article II, together with any cash in lieu of a fractional share and any dividends or distributions to which such Holder is entitled pursuant to Section 2.2(c).

(c)   No dividends or other distributions declared with respect to Parent Common Stock shall be paid to the Holder of any unsurrendered Certificate or untransferred Book-Entry Share until the Holder thereof shall surrender such Certificate or transfer such Book-Entry Share in accordance with this Article II. Subject to the effect of applicable abandoned property, escheat or similar Laws, following surrender of any such Certificate or transfer of such Book-Entry Share in accordance with this Article II, the Holder thereof shall be entitled to receive, without interest, the amount of any dividends or other distributions with a record date after the Effective Time, which theretofore had become payable with respect to the whole shares of Parent Common Stock to which the shares of Company Common Stock represented by such Certificate or Book-Entry Share have been converted into the right to receive and not paid.

(d)   If the Merger Consideration is to be delivered in exchange for a Certificate representing Company Common Stock to a Person other than the Person in whose name the Certificate so surrendered is registered in the stock transfer records of the Company, it shall be a condition to such exchange that (i) the Certificate so surrendered shall be properly endorsed or otherwise be in proper form for transfer and (ii) the Person requesting such payment or issuance shall pay any transfer or other similar Taxes required by reason of the payment or issuance to a Person other than the registered Holder of the Certificate or establish to the satisfaction of Parent that the Tax has been paid or is not applicable. The Exchange Agent (or, subsequent to the first anniversary of the Effective Time, Parent) shall be entitled to deduct and withhold from any portion of the Merger Consideration such amounts as the Exchange Agent or Parent, as the case may be, is required to deduct and withhold under the Code, or any provision of state, local or foreign Tax Law, with respect to the making of such payment. To the extent that the amounts are so withheld by the Exchange Agent or Parent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Holder of shares of Company Common Stock in respect of whom such deduction and withholding was made by the Exchange Agent or Parent, as the case may be.

(e)   After the Effective Time, there shall be no transfers on the stock transfer books of the Company of any shares of Company Common Stock that were issued and outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates representing such shares or Book-Entry Shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for the Merger Consideration, cash in lieu of a fractional share and any dividends or distributions to which such Holder is entitled pursuant to Section 2.2(c), in accordance with the procedures set forth in this Article II.

(f)   Notwithstanding anything to the contrary contained in this Agreement, no certificates or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender of Certificates or transfer of Book-Entry Shares for exchange, no dividend or distribution with respect to Parent Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of Parent. In lieu of the issuance of any such fractional share, Parent shall pay to each Holder of Company Common Stock who otherwise would be entitled to receive such fractional share, an amount in cash (rounded to the nearest whole cent) determined by multiplying (i) the Parent Share Value by (ii) the fraction of a share (after taking into account all shares of Company Common Stock held by such Holder at the Effective Time and rounded to the nearest one ten-thousandth when expressed in decimal form) of Parent Common Stock to which such Holder would otherwise be entitled to receive pursuant to Section 1.8. The parties acknowledge that payment of such cash consideration in lieu of issuing fractional shares was not separately bargained-for consideration, but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience that would otherwise be caused by the issuance of fractional shares.

(g)   Any portion of the Exchange Fund that remains unclaimed by the Holders of Company Common Stock as of the first anniversary of the Effective Time shall be returned to the Surviving Corporation. Any former Holders of Company Common Stock who have not theretofore complied with this Article II shall thereafter look only to the Surviving Corporation with respect to the Merger Consideration, any cash in lieu

TABLE OF CONTENTS

of fractional shares and any unpaid dividends and distributions on the Parent Common Stock deliverable in respect of each former share of Company Common Stock such Holder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Any Merger Consideration remaining unclaimed as of a date which is immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Entity shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation free and clear of any claims or interest of any Person previously entitled thereto. Notwithstanding the foregoing, none of Parent, the Company, the Surviving Corporation, the Exchange Agent or any other Person shall be liable to any former holder of shares of Company Common Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar Laws.

(h)   In the event that any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent or the Exchange Agent, the posting by such Person of a bond in such amount as Parent may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration, cash in lieu of fractional shares and any dividends or distributions to which such Holder is entitled pursuant to Section 2.2(c) deliverable in respect thereof pursuant to this Agreement.

(i)   Subject to the terms of this Agreement and the Exchange Agent Agreement, Parent, in the exercise of its reasonable discretion, shall have the right to make all determinations, not inconsistent with the terms of this Agreement, governing (i) the validity of any Letter of Transmittal and compliance by any Holder of Company Common Stock with the procedures and instructions set forth herein and therein, (ii) the issuance and delivery of the whole number of shares of the Parent Common Stock portion of the Merger Consideration, into which shares of Company Common Stock are converted in the Merger and (iii) the method of payment of cash in lieu of fractional shares of Parent Common Stock.

Shareholder’s capacity as a director or officer of the assertionCompany or any of dissentersits Subsidiaries or (subject to Section 3) as a fiduciary for others, including in exercising rights a written consent of the record holder. A beneficial owner may not dissent with respect to some but less than all shares of the same class or series owned by the owner, whether or not the shares so owned by him are registered in his name.

Section 1574. Notice of intention to dissent.

If the proposed corporate action is submitted to a vote at a meeting of shareholders of a business corporation, any person who wishes to dissent and obtain payment of the fair value of his shares must file with the corporation, prior to the vote, a written notice of intention to demand that he be paid the fair value for his shares if the proposed action is effectuated, must effect no change in the beneficial ownership of his shares from the date of such filing continuously through the effective date of the proposed action and must refrain from voting his shares in approval of such action. A dissenter who fails in any respect shall not acquire any right to payment of the fair value of his shares under this subchapter. Neither a proxy nor a vote against the proposed corporate action shall constitute the written notice required by this section.

Section 1575. Notice to demand payment.

(a) General rule.—If the proposed corporate action is approved by the required vote at a meeting of shareholders of a business corporation, the corporation shall mail a further notice to all dissenters who gave due notice of intention to demand payment of the fair value of their shares and who refrained from voting in favor of the proposed action. If the proposed corporate action is to be taken without a vote of shareholders, the corporation shall send to all shareholders who are entitled to dissent and demand payment of the fair value of their shares a notice of the adoption of the plan or other corporate action. In either case, the notice shall:

(1) State where and when a demand for payment must be sent and certificates for certificated shares must be deposited in order to obtain payment.

(2) Inform holders of uncertificated shares to what extent transfer of shares will be restricted from the time that demand for payment is received.

(3) Supply a form for demanding payment that includes a request for certification of the date on which the shareholder, or the person on whose behalf the shareholder dissents, acquired beneficial ownership of the shares.

(4) Be accompanied by a copy of this subchapter.

(b) Time for receipt of demand for payment.—The time set for receipt of the demand and deposit of certificated shares shall be not less than 30 days from the mailing of the notice.

Section 1576. Failure to comply with notice to demand payment, etc.

(a) Effect of failure of shareholder to act.—A shareholder who fails to timely demand payment, or fails (in the case of certificated shares) to timely deposit certificates, as required by a notice pursuant to section 1575 (relating to notice to demand payment) shall not have any right under this subchapter to receive payment of the fair value of his shares.

(b) Restriction on uncertificated shares.—If the shares are not represented by certificates, the business corporation may restrict their transfer from the time of receipt of demand for payment until effectuation of the proposed corporate action or the release of restrictions under the terms of section 1577(a) (relatingMerger Agreement, and no such actions or failures to failure to effectuate corporate action).

(c) Rights retained by shareholder.—The dissenter shall retain all other rights of a shareholder until those rights are modified by effectuation of the proposed corporate action.

Section 1577. Release of restrictions or payment for shares.

(a) Failure to effectuate corporate action.—Within 60 days after the date set for demanding payment and depositing certificates, if the business corporation has not effectuated the proposed corporate action, it shall return any certificates that have been deposited and release uncertificated shares from any transfer restrictions imposed by reason of the demand for payment.

(b) Renewal of notice to demand payment.—When uncertificated shares have been released from transfer restrictions and deposited certificates have been returned, the corporation may at any later time send a new notice conforming to the requirements of section 1575 (relating to notice to demand payment), with like effect.

(c) Payment of fair value of shares.—Promptly after effectuation of the proposed corporate action, or upon timely receipt of demand for payment if the corporate action has already been effectuated, the corporation shall either remit to dissenters who have made demand and (if their shares are certificated) have deposited their certificates the amount that the corporation estimates to be the fair value of the shares, or give written notice that no remittance under this section will be made. The remittance or notice shall be accompanied by:

(1) The closing balance sheet and statement of income of the issuer of the shares held or owned by the dissenter for a fiscal year ending not more than 16 months before the date of remittance or notice together with the latest available interim financial statements.

(2) A statement of the corporation’s estimate of the fair value of the shares.

(3) A notice of the right of the dissenter to demand payment or supplemental payment, as the case may be, accompanied by a copy of this subchapter.

(d) Failure to make payment.—If the corporation does not remit the amount of its estimate of the fair value of the shares as provided by subsection (c), it shall return any certificates that have been deposited and release uncertificated shares from any transfer restrictions imposed by reason of the demand for payment. The corporation may make a notation on any such certificate or on the records of the corporation relating to any such uncertificated shares that such demand has been made. If shares with respect to which notation has been so made shall be transferred, each new certificate issued therefor or the records relating to any transferred uncertificated shares shall bear a similar notation, together with the name of the original dissenting holder or owner of such shares. A transferee of such shares shall not acquire by such transfer any rights in the corporation other than those that the original dissenter had after making demand for payment of their fair value.

Section 1578. Estimate by dissenter of fair value of shares.

(a) General rule.—If the business corporation gives notice of its estimate of the fair value of the shares, without remitting such amount, or remits payment of its estimate of the fair value of a dissenter’s shares as permitted by section 1577(c) (relating to payment of fair value of shares) and the dissenter believes that the amount stated or remitted is less than the fair value of his shares, he may send to the corporation his own estimate of the fair value of the shares, whichact shall be deemed a demand for paymentbreach of this Agreement or shall be construed to prohibit, limit or restrict Shareholder from discharging Shareholder’s duties as a director or officer of the amountCompany or the deficiency.

(b) Effect of failure to file estimate.—Where the dissenter does not file his own estimate under subsection (a) within 30 days after the mailing by the corporationany of its remittanceSubsidiaries or notice, the dissenter shall be entitled(subject to no more than the amount stated in the notice or remitted to him by the corporation.

(b) Assessment of counsel fees and expert fees where lack of good faith appears.—Fees and expenses of counsel and of experts for the respective parties may be assessed as the court deems appropriate against the corporation and in favor of any or all dissenters if the corporation failed to comply substantially with the requirements of this subchapter and may be assessed against either the corporation or a dissenter, in favor of any other party, if the court finds that the party against whom the fees and expenses are assessed acted in bad faith or in a dilatory, obdurate, arbitrary or vexatious manner in respect to the rights provided by this subchapter.

(c) Award of fees for benefits to other dissenters.—If the court finds that the services of counsel for any dissenter were of substantial benefit to other dissenters similarly situated and should not be assessed against the corporation, it may award to those counsel reasonable fees to be paid out of the amounts awarded to the dissenters who were benefited.

PART II


INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.20. Indemnification of Directors and Officers.Officers.

Section 1741 of the Pennsylvania Business Corporation Law, or the PBCL, provides, in general, that a corporation will have the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), by reason of the fact that the person is or was a representative of the corporation, or is or was serving at the request of the corporation as a representative of another enterprise. Such indemnity may be against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with the action or proceeding, if the person acted in good faith and in a manner that the person reasonably believed to be in, or not opposed to, the best interests of the corporation and if, with respect to any criminal proceeding, the person did not have reasonable cause to believe his conduct was unlawful.

Section 1742 of the PBCL provides, in general, that a corporation will have the power to indemnify any person whothat was or is a party, or is threatened to be made a party, to any threatened, pending or completed action by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a representative of the corporation or is or was serving at the request of the corporation as a representative of another entity. Such indemnity may be against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of the action if the person acted in good faith and in a manner that the person reasonably believed to be in, or not opposed to, the best interests of the corporation, except no indemnification will be made in respect of any claim, issue, or matter as to which the person has been adjudged to be liable to the corporation unless and only to the extent that the court of common pleas of the judicial district embracing the county in which the registered office of the corporation is located or the court in which the action was brought will determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for the expenses that the court of common pleas or other court deems proper.

Under Section 1743 of the PBCL, the corporation is required to indemnify directors and officers against expenses they may incur in defending actions against them in such capacities if they are successful on the merits or otherwise in the defense of such actions. Under Section 1745 of the PBCL, a corporation may pay the expenses of a director or officer incurred in defending an action or proceeding in advance of the final disposition thereof upon receipt of an undertaking from such person to repay the amounts advanced unless it is ultimately determined that such person is entitled to indemnification from the corporation. Article V of S&T’s by-lawsbylaws provides indemnification of directors, officers and other agents of S&T and advancement of expenses to the extent otherwise permitted by Sections 1741, 1742 and 1745 of the PBCL.

Section 501 of S&T’s by-lawsbylaws provide that the rights to indemnification and advancement of expenses in the by-lawsbylaws are not exclusive, and may be in addition to, any rights granted to an indemnitee under S&T’s Articles of Incorporation, as amended from time to time, an agreement or vote of shareholders or disinterested directors or otherwise. As authorized by Section 1747 of the PBCL and Section 501(4) of S&T’s by-laws,bylaws, S&T maintains, on behalf of its directors and officers, insurance protection against certain liabilities arising out of the discharge of their duties, as well as insurance covering S&T for indemnification payments made to its directors and officers for certain liabilities. The premiums for such insurance are paid by S&T.

The foregoing is only a general summary of certain aspects of Pennsylvania law and S&T’s by-lawsbylaws dealing with indemnification of directors and officers, and does not purport to be complete. The description of the by-lawsbylaws is qualified in its entirety by reference to the detailed provisions of Article V, Section 501 of the by-lawsbylaws of S&T.
