(All comparisons refer to the fourth quarter of 2018, except as noted)

• Growth in total average loans was $1.3 billion, or 5.9%, with average commercial loan growth of $1.1 billion, or 7.8%, and average consumer loan growth of $223 million, or 2.7%.

• Total average deposits grew $1.3 billion, or 5.7%, primarily due to an increase in average non-interest-bearing deposits of $308 million, or 5.1%, and an increase in interest-bearing demand deposits of $1.5 billion, or 15.2%, partially offset by a decrease in average time deposits of $468 million, or 8.7%, largely from a $622 million managed decline in brokered CD balances.

• The loan to deposit ratio was 94.0% at December 31, 2019, compared to 94.4% at December 31, 2018.

Fourth Quarter 2019 Results – Comparison to Prior-Year Quarter

Net interest income totaled $226.4 million, decreasing $5.8 million, or 2.5%. The net interest margin (FTE) (non-GAAP) declined 22 basis points to 3.07%, reflecting lower yields on variable-rate loans due to lower benchmark interest rates during the second half of 2019. The fourth quarter of 2019 included $8.4 million of incremental purchase accounting accretion and $1.2 millionof cash recoveries compared to $8.3 million and $0.9 million, respectively, in the fourth quarter of 2018.

Total average earning assets increased$1.3 billion, or 4.7%, due to average loan growth of $1.3 billion. The total yield on average earning assets decreased to 4.13% from 4.31%, reflecting repricing of variable and adjustable-rate loans as the Federal Open Market Committee (FOMC) lowered its target rate 75 basis points during 2019. The total cost of funds increased to 1.08%, compared to 1.04%, due to higher interest rates on interest-bearing deposits and borrowings driven by continued deposit pricing competition, specifically higher rates on customer money market and time deposits. Average short-term borrowings decreased$764.8 million, while average long-term borrowings increased$712.8 million as we opportunistically secured long-term funding amidst the current low interest rate environment.

Average loans totaled $23.2 billion and increased$1.3 billion, or 5.9%, due to solid growth in the commercial and consumer portfolios. Average total commercial loan growth totaled $1.1 billion, or 7.8%, including $796 million, or

3

17.9%, growth in commercial and industrial loans and commercial real estate balances increased $178 million, or 2.0%. Commercial loan growth was led by strong activity in the Pittsburgh, Cleveland, Charlotte, Raleigh and Mid-Atlantic (Greater Baltimore-Washington D.C. markets) regions. Average consumer loan growth was $223 million, or 2.7%, with growth in residential mortgages of $305 million, or 10.0%, indirect auto loans of $28 million, or 1.5%, and direct installment loans of $15 million, or 0.8%, which were partially offset by a decline of $126 million, or 7.9%, in consumer lines of credit.

Average deposits totaled $24.8 billion, an increase of $1.3 billion, or 5.7%, supported by growth in interest-bearing demand deposits of $1.5 billion, or 15.2%, and non-interest-bearing deposits of $308 million, or 5.1%. The growth in non-interest-bearing and interest-bearing deposits was led by organic growth in personal and commercial relationships. The loan-to-deposit ratio was 94.0% at December 31, 2019, compared to 94.4% at December 31, 2018.

Non-interest income totaled $74.0 million, increasing $5.6 million, or 8.2%. On an operating basis, non-interest income increased $9.9 million, or 14.5%, when excluding $4.3 million in service charge refunds. Capital markets income grew $3.4 million, or 65.6%, reflecting strong customer-related interest rate derivative activity, while trust income grew $0.6 million, or 9.9%. Mortgage banking operations income increased$5.9 million, or 131.0%, due to a $4.9 million increase in gain on loans sold and included $1.9 million of a favorable interest rate-related valuation adjustment on mortgage servicing rights in the fourth quarter of 2019, compared to $0.5 million of unfavorable interest rate-related valuation adjustments in the fourth quarter of 2018. The insurance commissions and fees increase of $1.4 million represents the benefit from new business in the Mid-Atlantic and Carolina regions, as well as organic growth in commercial lines.

Non-interest expense totaled $177.4 million, increasing $7.7 million, or 4.5%. The primary drivers were increases in occupancy and equipment of $2.6 million, or 9.4%, due to investments in technology and strategic projects; and salaries and benefits of $3.8 million, or 4.1%, related primarily to annual merit increases and production-related commissions. These increases were partially offset by a $0.5 million, or 8.4%, decrease in FDIC insurance expense. The efficiency ratio (non-GAAP) totaled 56.0%, compared to 54.1%.

The ratio of non-performing loans and other real estate owned (OREO) to total loans and OREO decreased 6 basis points to 0.55%. For the originated portfolio, the ratio of non-performing loans and OREO to total loans and OREO decreased 2 basis points to 0.59%. Total delinquency remains at satisfactory levels, and total originated delinquency, defined as total past due and non-accrual originated loans as a percentage of total originated loans, increased 7 basis points to 0.71%, compared to 0.64% at December 31, 2018.

The provision for credit losses totaled $7.5 million, compared to $15.2 million. The provision for credit losses supported loan growth and exceeded net charge-offs of $5.3 million, or 0.09% annualized of total average loans, which declined from $13.4 million, or 0.24%. For the originated portfolio, net charge-offs were $5.3 million, or 0.10% annualized, of total average originated loans, compared to $12.1 million, or 0.27% annualized, of total average originated loans. The decline in net charge-offs was attributable to continued favorable asset quality trends. The ratio of the allowance for credit losses to total loans and leases was 0.84% and 0.81% at December 31, 2019, and December 31, 2018, respectively. For the originated portfolio, the allowance for credit losses to total originated loans was 0.93%, compared to 0.95% at December 31, 2018, directionally consistent with credit quality trends.

The effective tax rate was 17.6%, compared to 13.5%, due to benefits from renewable energy tax credits.

The tangible common equity to tangible assets ratio (non-GAAP) increased 53 basis points to 7.58% at December 31, 2019, compared to 7.05% at December 31, 2018. The tangible book value per common share (non-GAAP) was $7.53 at December 31, 2019, an increase of $0.85, or 13%, from $6.68 at December 31, 2018.

The total cost of funds decreased to 1.08% from 1.17%, reflecting lower borrowing costs, as well as a shift in funding mix and reductions in costs on

4

interest-bearing deposits. The cost of short-term borrowings decreased from 2.19% to 1.88% while the average balance decreased $268 million due to deposit growth.

Average loans totaled $23.2 billion with average commercial loan growth of $360 million, or 10.0% annualized, and an increase in average consumer loans of $143 million, or 6.8% annualized.

Non-interest expense totaled $177.4 million, a slight decrease of $0.4 million, or 0.2%. In the prior quarter, the Company recognized an impairment of $3.2 million from a third quarter renewable energy investment tax credit transaction which was offset by the fourth quarter 2019 salaries and employee benefits expense increase of $2.3 million, or 2.5%, mainly due to higher performance-based incentives, and occupancy and equipment expense increase of $1.7 million, or 6.0%, for investments in software and technology infrastructure.

2019 Full-Year Results - Comparison to Full-Year 2018 Period

Net interest income totaled $917.2 million, decreasing $15.3 million, or 1.6%, reflecting the sale of Regency in the third quarter of 2018 and a lower level of purchase accounting benefit, partially offset by average earning asset growth of $1.4 billion, or 5.1%. The net interest margin (FTE) (non-GAAP) contracted 22 basis points to 3.17%, primarily due to the sale of Regency, a lower level of cash recoveries on acquired loans and impact from the lower interest rate environment. Regency contributed 8 basis points to net interest margin for the full year of 2018. The full year of 2019 included $7.7 million of higher incremental purchase accounting accretion and $10.3 million of lower cash recoveries, compared to the full year of 2018. The yield on earning assets increased 6 basis points to 4.29%, while the cost of funds increased 28 basis points to 1.15%, primarily due to competitive pressure on interest-bearing deposits.

Average loans totaled $22.8 billion, an increase of $1.2 billion, or 5.5%, due to solid origination activity across the footprint. Growth in average commercial loans totaled $814 million, or 6.0%, including growth of $663 million, or 15.3%, in commercial and industrial loans and flat commercial real estate balances. Commercial growth was led by strong commercial activity in the Cleveland, Pittsburgh, Charlotte and the Mid-Atlantic regions. Total average consumer loan growth of $381 million, or 4.7%, was led by increases in residential mortgage loans of $368 million and indirect auto loans of $239 million, partially offset by a decline of $140 million in consumer credit lines and a decline of $86 million in direct installment balances.

Average deposits totaled $24.1 billion and increased$1.2 billion, or 5.4%, due to average growth of $727 million, or 7.7%, in interest-bearing demand deposits; $285 million, or 4.9%, in non-interest-bearing deposits; and $246 million, or 4.9%, in time deposits.

Non-interest income totaled $294.3 million, increasing $18.6 million, or 6.8%. On an operating basis, non-interest income increased $26.1 million, or 9.5%, attributable to the continued growth in our fee-based businesses of capital markets of $11.9 million, or 55.5%, reflecting deeper penetration among FNB's new and existing commercial relationships, and mortgage banking income of $9.7 million, or 44.4%, as sold mortgage production volume increased $281 million, or 24%, compared to prior year. Trust income increased $2.1 million, or8.0%, and insurance commissions and fees increased $2.2 million, or 11.7%.

Non-interest expense totaled $696.1 million, increasing $1.6 million, or 0.2%. On an operating basis, non-interest expense increased $2.6 million, or 0.4%. The increase in operating expenses was attributable mainly to an increase of $5.5 million, or 1.5%, in salaries and employee benefits, primarily due to normal merit increases; an increase of $5.2 million, or 4.5%, in occupancy and equipment expense, primarily due to technology investments; and a $3.2 million, or 3.8%, increase in other expenses reflecting an impairment from a third quarter renewable energy investment tax credit transaction of $3.2 million. The related renewable energy investment tax credits were recognized during the third quarter as a benefit to income taxes. These increases were mostly offset by the Regency sale and the elimination of the FDIC's large bank surcharge in the fourth quarter of 2018. The efficiency ratio (non-GAAP) totaled 54.5%, compared to 54.8% in 2018.

The provision for credit losses was $44.6 million, compared to $61.2 million. Net charge-offs totaled $28.3 million, or 0.12%, of total average loans, compared to $56.0 million, or 0.26%, in 2018 reflecting continued strong credit quality trends. Originated net charge-offs were 0.11% of total average originated loans, compared to 0.31% which included the impact from Regency for the first eight months of 2018.

The effective tax rate was 17.7% for 2019 compared to 17.6% in 2018.

Use of Non-GAAP Financial Measures and Key Performance Indicators

To supplement our Consolidated Financial Statements presented in accordance with GAAP, we use certain non-GAAP financial measures, such as operating net income available to common stockholders, operating earnings per diluted common share, return on average tangible equity, return on average tangible common equity, return on average tangible assets, tangible book value per common share, the ratio of tangible equity to tangible assets, the ratio of tangible common equity to tangible assets, efficiency ratio, and net interest margin (FTE) to provide information useful to investors in understanding our operating performance and trends, and to facilitate comparisons with the performance of our peers. Management uses these measures internally to assess and better understand our underlying business performance and trends related to core business activities. The non-GAAP financial measures and key performance indicators we use may differ from the non-GAAP financial measures and key performance indicators other financial institutions use to assess their performance and trends.

6

These non-GAAP financial measures should be viewed as supplemental in nature, and not as a substitute for or superior to, our reported results prepared in accordance with GAAP. When non-GAAP financial measures are disclosed, the Securities and Exchange Commission's (SEC) Regulation G requires: (i) the presentation of the most directly comparable financial measure calculated and presented in accordance with GAAP and (ii) a reconciliation of the differences between the non-GAAP financial measure presented and the most directly comparable financial measure calculated and presented in accordance with GAAP. Reconciliations of non-GAAP operating measures to the most directly comparable GAAP financial measures are included in the tables at the end of this release under the heading “Reconciliations of Non-GAAP Financial Measures and Key Performance Indicators to GAAP”.

Management believes charges such as branch consolidation costs, service charge refunds and special one-time employee 401(k) contributions related to tax reform are not organic costs to run our operations and facilities. These charges are considered significant items impacting earnings as they are deemed to be outside of ordinary banking activities. The branch consolidation charges principally represent expenses to satisfy contractual obligations of the closed branches without any useful ongoing benefit to us. These costs are specific to each individual transaction and may vary significantly based on the size and complexity of the transaction. Similarly, gains derived from the sale of a business are not organic to our operations.

To provide more meaningful comparisons of net interest margin and efficiency ratio, we use net interest income on a taxable-equivalent basis in calculating net interest margin by increasing the interest income earned on tax-exempt assets (loans and investments) to make it fully equivalent to interest income earned on taxable investments (this adjustment is not permitted under GAAP). Taxable-equivalent amounts for the 2019 and 2018 periods were calculated using a federal statutory income tax rate of 21%.

(2	)	Includes all other real estate owned, including those balances acquired through business combinations that have been in the acquired portfolio prior to foreclosure.
(3	)	"Originated Portfolio" or "Originated Loans and Leases" equals loans and leases not included by definition in the Acquired Portfolio.
(4	)	"Acquired Portfolio" or "Loans Acquired in a Business Combination" equals loans acquired at fair value, accounted for in accordance with ASC 805. The risk of credit loss on these loans has been considered by virtue of our estimate of acquisition-date fair value and these loans are considered accruing as we primarily recognize interest income through accretion of the difference between the carrying value of these loans and their expected cash flows.  Because loans acquired in a business combination are initially recorded at an amount estimated to be collectible, losses on such loans, when incurred, are first applied against the non-accretable difference established in purchase accounting and then to any allowance for credit losses recognized subsequent to acquisition.
(5	)	Represents contractual balances.
