Prior periods' consolidated financial statements are reclassified whenever necessary to conform to the current periods' presentation.

Use of Estimates in the Preparation of Financial Statements

In preparing the consolidated financial statements in accordance with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the respective consolidated balance sheets and the reported amounts of revenues and expenses for the periods presented. Actual results could differ significantly from those estimates.

Material estimates that are particularly susceptible to change relate to the determination of the ACL; estimates of fair value; income taxes; and contingent liabilities.

Recently Adopted Accounting Standards

ASU 2020-08, Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable Fees and Other Costs. The guidance in this ASU pertains to the shortened amortization period for certain purchased callable debt securities held at a premium, which premium is amortized to the earliest call date in accordance with ASC 310-20-25-33, and clarifies that an entity should reevaluate whether a callable debt security is within the scope of paragraph 310-20-25-33 for each reporting period. The amendments in this ASU are effective for fiscal years beginning after December 15, 2020. Synovus adopted ASU 2020-08 effective January 1, 2021 with no material impact to the unaudited consolidated financial statements.

ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. In December 2019, the FASB issued ASU 2019-12 to simplify and reduce complexities when accounting for income taxes by removing certain exceptions. Among the provisions of this guidance are the requirement that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. ASU 2019-12 is effective for public entities for fiscal years beginning after December 15, 2020. Synovus adopted ASU 2019-12 effective January 1, 2021 with no material impact to the unaudited consolidated financial statements unless there are changes in tax law that require recognition as set forth in this guidance.

Recently Issued Accounting Standards Not Yet Adopted

As of March 31, 2021, Synovus had 115 investment securities in a loss position for less than twelve months and no investment securities in a loss position for twelve months or longer. Synovus does not intend to sell investment securities in an unrealized loss position prior to the recovery of the unrealized loss, which may not be until maturity, and has the ability and intent to hold those securities for that period of time. Additionally, Synovus is not currently aware of any circumstances which will require it to sell any of the securities that are in an unrealized loss position prior to the respective securities' recovery of all such unrealized losses. As such, no write-downs to the amortized cost basis of the portfolio were recorded at March 31, 2021.

At March 31, 2021, no ACL was established for investment securities. Substantially all of the unrealized losses on the securities portfolio were the result of changes in market interest rates compared to the date the securities were acquired rather than the credit quality of the issuers or underlying loans. U.S. Treasury and agency securities and agency mortgage-backed securities are issued, guaranteed or otherwise supported by the United States government, an agency of the United States government, or a government sponsored enterprise.

The amortized cost and fair value by contractual maturity of investment securities available for sale at March 31, 2021 are shown below. The expected life of MBSs or CMOs may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. For purposes of the maturity table, MBSs and CMOs, which are not due at a single maturity date, have been classified based on the final contractual maturity date.

Pledged Loans

Loans with carrying values of $14.27 billion and $15.05 billion, respectively, were pledged as collateral for borrowings and capacity at March 31, 2021 and December 31, 2020, respectively, to the FHLB and Federal Reserve Bank.

Portfolio Segment Risk Factors

The risk characteristics and collateral information of each portfolio segment are as follows:

Commercial and Industrial Loans - The C&I loan portfolio is comprised of general middle market and commercial banking clients across a diverse set of industries. In accordance with Synovus' lending policy, each loan undergoes a detailed underwriting process which incorporates uniform underwriting standards and oversight in proportion to the size and complexity of the lending relationship. These loans are secured by collateral such as business equipment, inventory, and real estate. Whether for real estate or non-real estate purpose, credit decisions on loans in the C&I portfolio are based on cash flow from the operations of the business as the primary source of repayment of the debt, with underlying real estate or other collateral being the secondary source of repayment. PPP loans, which are categorized as C&I loans, were $2.36 billion at March 31, 2021 and are guaranteed by the SBA.

Commercial Real Estate Loans - CRE loans primarily consist of income-producing investment properties loans. Additionally, CRE loans include 1-4 family properties loans as well as land and development loans. Investment properties loans consist of construction and mortgage loans for income-producing properties and are primarily made to finance multi-family properties, hotels, office buildings, shopping centers, warehouses and other commercial development properties. 1-4 family properties loans include construction loans to homebuilders and commercial mortgage loans related to 1-4 family rental properties and are almost always secured by the underlying property being financed by such loans. These properties are primarily located in the markets served by Synovus. Land and development loans include commercial and residential development as well as land acquisition loans and are secured by land held for future development, typically in excess of one year. Properties securing these loans are substantially within markets served by Synovus, and loan terms generally include personal guarantees from the principals. Loans in this portfolio are underwritten based on the LTV of the collateral and the capacity of the guarantor(s).

Consumer Loans - The consumer loan portfolio consists of a wide variety of loan products offered through Synovus' banking network including first and second residential mortgages, HELOCs, and credit card loans, as well as home improvement loans, student, personal, and auto loans from third-party lending. The majority of Synovus' consumer loans are consumer mortgages and HELOCs secured by first and second liens on residential real estate primarily located in the markets served by Synovus. The primary source of repayment for all consumer loans is generally the personal income of the borrower(s).

Credit Quality Indicators

The credit quality of the loan portfolio is reviewed and updated no less frequently than quarterly using the standard asset classification system utilized by the federal banking agencies. These classifications are divided into three groups: Not Criticized (Pass), Special Mention, and Classified or Adverse rating (Substandard, Doubtful, and Loss) and are defined as follows:

Pass - loans which are well protected by the current net worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less cost to acquire and sell in a timely manner, of any underlying collateral.

Special Mention - loans which have potential weaknesses that deserve management's close attention. These loans are not adversely classified and do not expose an institution to sufficient risk to warrant an adverse classification.

Substandard - loans which are inadequately protected by the current net worth and paying capacity of the obligor or by the collateral pledged, if any. Loans with this classification are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

Doubtful - loans which have all the weaknesses inherent in loans classified as Substandard with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable on the basis of currently known facts, conditions, and values.

Loss - loans which are considered by management to be uncollectible and of such little value that their continuance on the institution's books as an asset, without establishment of a specific valuation allowance or charge-off, is not warranted. Synovus fully reserves for any loans rated as Loss.

In the following tables, consumer loans are generally assigned a risk grade similar to the classifications described above; however, upon reaching 90 days and 120 days past due, they are generally downgraded to Substandard and Loss, respectively, in accordance with the FFIEC Retail Credit Classification Policy. Additionally, in accordance with Interagency Supervisory Guidance, the risk grade classifications of consumer loans (consumer mortgages and HELOCs) secured by junior liens on 1-4

11

family residential properties also consider available information on the payment status of any associated senior liens with other financial institutions.

The following tables summarize each loan portfolio class by risk grade and origination year as of March 31, 2021 and December 31, 2020 as required under CECL.

Collateral-Dependent Loans

We classify a loan as collateral-dependent when our borrower is experiencing financial difficulty, and we expect repayment to be provided substantially through the operation or sale of collateral. Our commercial loans have collateral that is comprised of real estate and business assets. Our consumer loans have collateral that is substantially comprised of residential real estate.

There were no significant changes in the extent to which collateral secures our collateral-dependent loans during the three months ended March 31, 2021.

Rollforward of Allowance for Loan Losses

The following tables detail the changes in the ALL by loan segment for the three months ended March 31, 2021 and 2020.

Ending balance	$	216,950	$	107,117	$	169,385	$	493,452

The ALL of $563.2 million and the reserve for unfunded commitments of $51.5 million, which is recorded in other liabilities, comprise the total ACL of $614.7 million at March 31, 2021, which decreased during the first quarter of 2021 by $38.8 million, resulting in an ACL to loans coverage ratio of 1.58%. The modeling assumptions for the first quarter of 2021 utilized a two-year reasonable and supportable forecast period and comprised a multiple-scenario economic framework. To the extent the lives of the loans in the portfolio extend beyond the period for which a reasonable and supportable forecast can be made, the Company reverts, on a straight-line basis back to the historical rates over a one-year period. The ACL at March 31, 2021 incorporates a baseline outlook with moderate economic expansion and benefits from the estimated impact of government stimulus. Provision for credit losses includes the provisions for loan losses and unfunded commitments. The reversal of provision for credit losses of $18.6 million for the three months ended March 31, 2021 included net charge-offs of $20.2 million and resulted from the improved economic outlook and stable loan portfolio metrics that were partially offset by the increased size of the loan portfolio including $15.2 million in reserves added as result of purchases of $607.0 million of third-party lending loans, including a $476.2 million prime auto purchase.

Goodwill allocated to each reporting unit at March 31, 2021 and December 31, 2020 is presented as follows (the FMS reportable segment includes two reporting units of Consumer Mortgage and Wealth Management):

(in thousands)	Community Banking Reporting Unit		Wholesale Banking Reporting Unit		Consumer Mortgage Reporting Unit		Wealth Management Reporting Unit		Total
Balance as of December 31, 2020	$	256,323	$	171,636	$	—	$	24,431	$	452,390

Balance as of March 31, 2021	$	256,323	$	171,636	$	—	$	24,431	$	452,390

Goodwill is not amortized but is evaluated for impairment on an annual basis or whenever an event occurs or circumstances change to indicate that it is more likely than not that an impairment loss has been incurred (i.e., a triggering event). Synovus performs its annual evaluation of goodwill impairment during the fourth quarter of each year. See "Part II - Item 8. Financial Statements and Supplementary Data - Note 7 - Goodwill and Other Intangible Assets" to the consolidated financial statements of Synovus' 2020 Form 10-K for information on Synovus' quantitative assessments of goodwill impairment during 2020.

The following table shows the gross carrying amount and accumulated amortization of other intangible assets as of March 31, 2021 and December 31, 2020, which primarily consist of core deposit intangible assets. The CDI is being amortized over its estimated useful life of approximately ten years utilizing an accelerated method. Aggregate other intangible assets amortization expense for the three months ended March 31, 2021 and 2020 was $2.4 million and $2.6 million, respectively.

(in thousands)	Gross Carrying Amount		Accumulated Amortization		Net Carrying Value

Fair Value Option

Synovus has elected the fair value option for mortgage loans held for sale primarily to ease the operational burden required to maintain hedge accounting for these loans. Synovus is still able to achieve effective economic hedges on mortgage loans held for sale without the time and expense needed to manage a hedge accounting program.

The following table summarizes the difference between the fair value and the UPB of mortgage loans held for sale and the changes in fair value of these loans. An immaterial portion of these changes in fair value was attributable to changes in instrument-specific credit risk.

Note 7 - Derivative Instruments and Hedging Activities

Synovus utilizes derivative instruments to manage its exposure to various types of interest rate risk, exposures related to liquidity and credit risk, and to facilitate customer transactions. The primary types of derivative instruments utilized by Synovus consist of interest rate swaps, interest rate lock commitments made to prospective mortgage loan customers, commitments to sell fixed-rate mortgage loans, and foreign currency exchange forwards. Interest rate lock commitments represent derivative instruments since it is intended that such loans will be sold. Synovus is party to master netting arrangements with its dealer counterparties; however, Synovus does not offset assets and liabilities under these arrangements for financial statement presentation purposes. See "Part II - Item 8. Financial Statements and Supplementary Data - Note 1 - Summary of Significant Accounting Policies" to the consolidated financial statements of Synovus' 2020 Form 10-K for additional information regarding accounting policies for derivatives.

Hedging Derivatives

Cash flow hedge relationships mitigate exposure to the variability of future cash flows or other forecasted transactions. Synovus has entered into interest rate swap contracts to manage overall cash flow changes related to interest rate risk exposure on index-based variable rate commercial loans. The contracts effectively modify Synovus' exposure to interest rate risk by utilizing receive fixed/pay index-based variable rate interest rate swaps.

For cash flow hedges, if the hedged exposure is a cash flow exposure, the effective portion of the gain or loss on the derivative instrument is reported initially as a component of accumulated other comprehensive income (loss), net of the tax impact, and subsequently reclassified into earnings when the hedged transaction affects earnings with the impacts recorded in the same income statement line item used to present the earnings effect of the hedged item. When a cash flow hedge relationship is discontinued but the hedged cash flows, or forecasted transactions, are still expected to occur, gains or losses that were accumulated in OCI are amortized into earnings over the same periods which the hedged transactions would have affected earnings. If, however, it is probable the forecasted transactions will no longer occur, the remaining accumulated amounts in OCI at the de-designation date are immediately recognized in earnings.

Synovus recorded unrealized gains of $757 thousand, or $565 thousand, after tax, in OCI during the first quarter of 2021 and $9.8 million, or $7.3 million, after-tax, in OCI, during the first quarter of 2020, related to terminated cash flow hedges, which are being recognized into earnings in conjunction with the effective terms of the original swaps through the fourth

24

quarter of 2025. Synovus recognized pre-tax income of $1.6 million during the three months ended March 31, 2021 related to the amortization of terminated cash flow hedges.

As of March 31, 2021, Synovus expects to reclassify into earnings approximately $43 million in pre-tax income due to the receipt or payment of interest payments on all cash flow hedges within the next twelve months. Included in this amount is approximately $13 million in pre-tax income related to the amortization of terminated cash flow hedges. As of March 31, 2021, the maximum length of time over which Synovus is hedging its exposure to the variability in future cash flows is through the first quarter of 2026.

For derivative instruments that are not designated as hedging instruments, changes in the fair value of the derivatives are recognized in earnings immediately.

Counterparty Credit Risk and Collateral

Entering into derivative contracts potentially exposes Synovus to the risk of counterparties’ failure to fulfill their legal obligations, including, but not limited to, potential amounts due or payable under each derivative contract. Notional principal amounts are often used to express the volume of these transactions, but the amounts potentially subject to credit risk are much smaller. Synovus assesses the credit risk of its dealer counterparties by regularly monitoring publicly available credit rating information, evaluating other market indicators, and periodically reviewing detailed financials. Dealer collateral requirements are determined via risk-based policies and procedures and in accordance with existing agreements. Synovus seeks to minimize dealer credit risk by dealing with highly rated counterparties and by obtaining collateral for exposures above certain predetermined limits. Management closely monitors credit conditions within the customer swap portfolio, which management deems to be of higher risk than dealer counterparties. Collateral is secured at origination and credit related fair value adjustments are recorded against the asset value of the derivative as deemed necessary based upon an analysis, which includes consideration of the current asset value of the swap, customer risk rating, collateral value, and customer standing with regards to its swap contractual obligations and other related matters. Such asset values fluctuate based upon changes in interest rates regardless of changes in notional amounts and changes in customer specific risk.

Collateral Requirements

Pursuant to the Dodd-Frank Act, certain derivative transactions have collateral requirements, both at the inception of the trade and as the value of each derivative position changes. As of March 31, 2021 and December 31, 2020, collateral totaling $121.7 million and $155.4 million, respectively, was pledged to the derivative counterparties to comply with collateral requirements. For derivatives cleared through central clearing houses, the variation margin payments made are legally characterized as settlements of the derivatives. As a result, these variation margin payments are netted against the fair value of the respective derivative contracts in the consolidated balance sheets and related disclosures. At March 31, 2021 and December 31, 2020, Synovus had a variation margin of $81.8 million and $162.7 million respectively, each reducing the derivative liability.

(4)    Includes risk participation agreements sold. Additionally, the notional amount of risk participation agreements purchased was $2.5 million and $2.6 million at March 31, 2021 and December 31, 2020, respectively.

Synovus also provides foreign currency exchange services, primarily forward contracts, with counterparties to allow commercial customers to mitigate exchange rate risk. Synovus covers its risk by entering into an offsetting foreign currency exchange forward contract. The notional amount of foreign currency exchange forwards was $18.4 million and $24.1 million at March 31, 2021 and December 31, 2020, respectively. The fair value of foreign currency exchange forwards was negligible at March 31, 2021 and December 31, 2020 due to the very short duration of these contracts.

As of March 31, 2021 and 2020, there were 32 thousand and 557 thousand, respectively, potentially dilutive shares related to stock options to purchase shares of common stock that were outstanding during these quarters. Potentially dilutive shares are not included in the computation of diluted net income per common share because the effect would be anti-dilutive.

Note 9 - Commitments and Contingencies

In the normal course of business, Synovus enters into commitments to extend credit such as loan commitments and letters of credit to meet the financing needs of its customers. Synovus uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. 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. Synovus also has commitments to fund certain low-income housing investments, solar energy, and CRA investments.

The contractual amount of these financial instruments represents Synovus' maximum credit risk should the counterparty draw upon the commitment, and should the counterparty subsequently fail to perform according to the terms of the contract. Since many of the commitments are expected to expire without being drawn upon, total commitment amounts do not necessarily represent future cash requirements. Additionally, certain commitments (primarily consumer) can generally be canceled by providing notice to the borrower.

27

The ACL associated with unfunded commitments and letters of credit is recorded within other liabilities on the consolidated balance sheets. At March 31, 2021, the ACL for unfunded commitments was $51.5 million, compared to a reserve of $47.8 million at December 31, 2020. Additionally, an immaterial amount of unearned fees relating to letters of credit are recorded within other liabilities on the consolidated balance sheets.

Synovus invests in certain LIHTC partnerships which are engaged in the development and operation of affordable multi-family housing pursuant to Section 42 of the Code. Additionally, Synovus invests in certain solar energy tax credit partnerships pursuant to Section 48 of the Code. Synovus typically acts as a limited partner in these investments and does not exert control over the operating or financial policies of the partnerships and as such, is not considered the primary beneficiary of the partnership. For certain of its LIHTC investments, Synovus provides financing during the construction and development of the properties and is at risk for the funded amount of its equity investment plus the outstanding amount of any construction loans in excess of the fair value of the collateral for the loan, but has no obligation to fund the operations or working capital of the partnerships and is not exposed to losses beyond Synovus’ investment. Synovus receives tax credits related to these investments which are subject to recapture by taxing authorities based on compliance provisions required to be met at the project level.

Synovus also invests in certain other CRA partnerships including SBIC programs. The SBIC is a program initiated by the SBA in 1958 to assist in the funding of small business loans.

Merchant Services

In accordance with credit and debit card association rules, Synovus provides merchant processing services for customers with a contractual arrangement under which certain sales and processing support are provided through an outside merchant services provider with Synovus owning the merchant contract relationship. In addition, Synovus sponsors various third-party MPS businesses that process credit and debit card transactions on behalf of merchants. In connection with these services, a liability may arise in the event of a billing dispute between the merchant and a cardholder that is ultimately resolved in the cardholder's favor. If the merchant defaults on its obligations, the cardholder, through its issuing bank, generally has until six months after the date of the transaction to present a chargeback to the MPS, which is primarily liable for any losses on covered transactions. However, if a sponsored MPS fails to meet its obligations, then Synovus, as the sponsor, could be held liable for the disputed amount. Synovus seeks to mitigate this risk through its contractual arrangements with the MPS and the merchants by withholding future settlements, retaining cash reserve accounts and/or obtaining other security. For the three months ended March 31, 2021 and 2020, Synovus and the sponsored entities processed and settled $26.03 billion and $18.37 billion of transactions, respectively.

Synovus covered chargebacks related to a particular sponsored MPS during 2019 and 2018 where the MPS’s cash reserve account was unavailable to support the chargebacks. As of March 31, 2021, the remaining amount, net of reserves, included in other assets and classified in NPAs, is $15.5 million, compared to $15.6 million at December 31, 2020. While Synovus has contractual protections to mitigate against loss, repayment of the amounts owed to Synovus will depend in large part upon the continued financial viability and/or valuation of the MPS.

28

Legal Proceedings

Synovus and its subsidiaries are subject to various legal proceedings, claims and disputes that arise in the ordinary course of its business. Additionally, in the ordinary course of business, Synovus and its subsidiaries are subject to regulatory and governmental examinations, information gathering requests, inquiries and investigations. Synovus, like many other financial institutions, has been the target of legal actions and other proceedings asserting claims for damages and related relief for losses. These actions include mortgage loan and other loan put-back claims, claims and counterclaims asserted by individual borrowers related to their loans, allegations of violations of state and federal laws and regulations relating to banking practices, and allegations related to Synovus' participation in government stimulus programs, including putative class action matters. In addition to actual damages, if Synovus does not prevail in such asserted legal actions, credit-related litigation could result in additional write-downs or charge-offs of assets, which could adversely affect Synovus' results of operations during the period in which the write-down or charge-off were to occur.

Synovus carefully examines and considers each legal matter, and, in those situations where Synovus determines that a particular legal matter presents loss contingencies that are both probable and reasonably estimable, Synovus establishes an appropriate reserve. An event is considered to be probable if the future event is likely to occur. While the final outcome of any legal proceeding is inherently uncertain, based on the information currently available, advice of counsel and available insurance coverage, management believes that the amounts accrued with respect to legal matters as of March 31, 2021 are adequate. The actual costs of resolving legal claims may be higher or lower than the amounts accrued.

In addition, where Synovus determines that there is a reasonable possibility of a loss in respect of legal matters, Synovus considers whether it is able to estimate the total reasonably possible loss or range of loss. An event is “reasonably possible” if “the chance of the future event or events occurring is more than remote but less than likely.” An event is “remote” if “the chance of the future event or events occurring is more than slight but less than reasonably possible." In many situations, Synovus may be unable to estimate reasonably possible losses due to the preliminary nature of the legal matters, as well as a variety of other factors and uncertainties. For those legal matters where Synovus is able to estimate a range of reasonably possible losses, management currently estimates the aggregate range from our outstanding litigation is from zero to $5 million in excess of the amounts accrued, if any, related to those matters. This estimated aggregate range is based upon information currently available to Synovus, and the actual losses could prove to be lower or higher. As there are further developments in these legal matters, Synovus will reassess these matters, and the estimated range of reasonably possible losses may change as a result of this assessment. Based on Synovus' current knowledge and advice of counsel, management presently does not believe that the liabilities arising from these legal matters will have a material adverse effect on Synovus' consolidated financial condition, results of operations or cash flows. However, it is possible that the ultimate resolution of these legal matters could have a material adverse effect on Synovus' results of operations or financial condition for any particular period.

Synovus intends to vigorously pursue all available defenses to these legal matters, but will also consider other alternatives, including settlement, in situations where there is an opportunity to resolve such legal matters on terms that Synovus considers to be favorable, including in light of the continued expense and distraction of defending such legal matters. Synovus maintains insurance coverage, which may be available to cover legal fees, or potential losses that might be incurred in connection with such legal matters. The above-noted estimated range of reasonably possible losses does not take into consideration insurance coverage which may or may not be available for the respective legal matters.

Note 10 - Segment Reporting

Synovus' business segments are based on the products and services provided or the customers served and reflect the manner in which financial information is evaluated by the chief operating decision makers. Synovus has three major reportable business segments: Community Banking, Wholesale Banking, and Financial Management Services (FMS), with functional activities such as treasury, technology, operations, marketing, finance, enterprise risk, legal, human resources, corporate communications, executive management, among others, included in Treasury and Corporate Other.

Business segment results are determined based upon Synovus' management reporting system, which assigns balance sheet and income statement items to each of the business segments. Certain assets, liabilities, revenues, and expenses not allocated or attributable to a particular business segment are included in Treasury and Corporate Other. Synovus's third-party lending consumer loans and held for sale loans as well as PPP loans are included in Treasury and Corporate Other. The management accounting policies and processes utilized in compiling segment financial information are highly subjective and, unlike financial accounting, are not based on authoritative guidance similar to GAAP. As a result, reported segment results are not necessarily comparable with similar information reported by other financial institutions.

The Community Banking business segment serves customers using a relationship-based approach through its branch, ATM, commercial, and private wealth network in addition to mobile, Internet, and telephone banking. This segment primarily provides individual, small business, and corporate customers with an array of comprehensive banking products and services including commercial, home equity, and other consumer loans, credit and debit cards, and deposit accounts.

29

The Wholesale Banking business segment serves primarily larger corporate customers by providing commercial lending and deposit services through specialty teams including middle market, CRE, senior housing, national accounts, premium finance, structured lending, healthcare, asset-based lending, and community investment capital.

The Financial Management Services (FMS) business segment serves its customers by providing mortgage and trust services and also specializing in professional portfolio management for fixed-income securities, investment banking, the execution of securities transactions as a broker/dealer, asset management, financial planning, and family office services, as well as the provision of individual investment advice on equity and other securities.

Synovus uses a centralized FTP methodology to attribute appropriate net interest income to the business segments. The intent of the FTP methodology is to transfer interest rate risk from the business segments by providing matched duration funding of assets and liabilities. The result is to centralize the financial impact, management, and reporting of interest rate risk in the Treasury and Corporate Other function where it can be centrally monitored and managed. Treasury and Corporate Other includes certain assets and/or liabilities managed within that function. Additionally, Treasury and Corporate Other also charges (credits) an internal cost of funds for assets held in (or pays for funding provided by) each business segment. The process for determining FTP is based on a number of factors and assumptions, including prevailing market interest rates, the expected lives of various assets and liabilities, and the Company's broader funding profile.

The following tables present certain financial information for each reportable business segment for the three months ended March 31, 2021 and 2020. The application and development of management reporting methodologies is a dynamic process and is subject to periodic enhancements. As these enhancements are made, financial results presented by each reportable business segment may be periodically revised.

In this Report, the words “Synovus,” “the Company,” “we,” “us,” and “our” refer to Synovus Financial Corp. together with Synovus Bank and Synovus' other wholly-owned subsidiaries, except where the context requires otherwise.

FORWARD-LOOKING STATEMENTS

Certain statements made or incorporated by reference in this Report which are not statements of historical fact, including those under “Management's Discussion and Analysis of Financial Condition and Results of Operations,” and elsewhere in this Report, constitute forward-looking statements within the meaning of, and subject to the protections of, Section 27A of the Securities Act and Section 21E of the Exchange Act. Forward-looking statements include statements with respect to Synovus' beliefs, plans, objectives, goals, targets, expectations, anticipations, assumptions, estimates, intentions and future performance and involve known and unknown risks, many of which are beyond Synovus' control and which may cause Synovus' actual results, performance or achievements or the financial services industry or economy generally, to be materially different from future results, performance or achievements expressed or implied by such forward-looking statements.

All statements other than statements of historical fact are forward-looking statements. You can identify these forward-looking statements through Synovus' use of words such as “believes,” “anticipates,” “expects,” “may,” “will,” “assumes,” “predicts,” “could,” “should,” “would,” “intends,” “targets,” “estimates,” “projects,” “plans,” “potential” and other similar words and expressions of the future or otherwise regarding the outlook for Synovus' future business and financial performance and/or the performance of the financial services industry and economy in general. Forward-looking statements are based on the current beliefs and expectations of Synovus' management and are subject to significant risks and uncertainties. Actual results may differ materially from those contemplated by such forward-looking statements. A number of factors could cause actual results to differ materially from those contemplated by the forward-looking statements in this document. Many of these factors are beyond Synovus' ability to control or predict. These factors include, but are not limited to:

(1) the risks and uncertainties related to the impact of the COVID-19 pandemic on our assets, business, capital and liquidity, financial condition, prospects and results of operations;

(2) the risk that we may not realize the expected benefits from our efficiency and growth initiatives or that we may not be able to realize such cost savings or revenue benefits in the time period expected, which could negatively affect our future profitability;

(3) the risk that any economic downturn and contraction could have a material adverse effect on our capital, financial condition, credit quality, results of operations and future growth, including the risk that the current economic contraction could last much longer and be more severe if efforts to contain the pandemic are unsuccessful;

(4) the risk that competition in the financial services industry may adversely affect our future earnings and growth;

(5) our ability to attract and retain employees and the impact of executive management transitions that are key to our growth and efficiency strategies;

(6) risks that our asset quality may deteriorate, our allowance for credit losses may prove to be inadequate or may be negatively affected by credit risk exposures, and the risk that we may be unable to obtain full payment in respect of any loan or other receivables;

(7) the impact of recent and proposed changes in governmental policy, laws and regulations, including recently enacted laws, regulations and guidance related to government stimulus programs related to the COVID-19 pandemic, proposed and recently enacted changes in monetary policy and in the regulation and taxation of banks and financial institutions, or the interpretation or application thereof and the uncertainty of future implementation and enforcement of these regulations;

(8) changes in the interest rate environment, including changes to the federal funds rate to include a negative interest rate environment, and competition in our primary market area may result in increased funding costs or reduced earning assets yields, thus reducing margins and net interest income;

(9) the risk that our current and future information technology system enhancements and operational initiatives may not be successfully implemented, which could negatively impact our operations;

32

(10) risks related to our implementation of new lines of business, new products and services or new technologies;

(11) risks related to our business relationships with, and reliance upon, third parties that have strategic partnerships with us or that provide key components of our business infrastructure, including the costs of services and products provided to us by third parties, and risks related to disruptions in service or financial difficulties with a third-party vendor or business relationship;

(12) the risk that our enterprise risk management framework, our compliance program, or our corporate governance and supervisory oversight functions may not identify or address risks adequately, which may result in unexpected losses;

(13) the risk that we may be required to make substantial expenditures to keep pace with regulatory initiatives and the rapid technological changes in the financial services market;

(14) changes in the cost and availability of funding due to changes in the deposit market and credit market;

(15) risks related to the ability of our operational framework to identify and manage risks associated with our business such as credit risk, compliance risk, reputational risk, and operational risk, including by virtue of our relationships with third-party business partners, as well as our relationship with third-party vendors and other service providers;

(16) our ability to identify and address cyber-security risks such as data security breaches, malware, "denial of service" attacks, "hacking" and identity theft, a failure of which could disrupt our business and result in the disclosure of and/or misuse or misappropriation of confidential or proprietary information, disruption or damage of our systems, increased costs, significant losses, or adverse effects to our reputation;

(17) the risk that we may be exposed to potential losses in the event of fraud and/or theft, or in the event that a third-party vendor, obligor, or business partner fails to pay amounts due to us under that relationship or under any arrangement that we enter into with them;

(18) the impact on our financial results, reputation, and business if we are unable to comply with all applicable federal and state regulations or other supervisory actions or directives and any necessary capital initiatives;

(19) the risks that if economic conditions worsen further or regulatory capital rules are modified, we may be required to undertake initiatives to improve or conserve our capital position;

(20) risks related to the continued use, availability and reliability of LIBOR and the risks related to the transition from LIBOR to other benchmark rates;

(21) restrictions or limitations on access to funds from historical and alternative sources of liquidity could adversely affect our overall liquidity, which could restrict our ability to make payments on our obligations and our ability to support asset growth and sustain our operations and the operations of Synovus Bank;

(22) our ability to receive dividends from our subsidiaries could affect our liquidity, including our ability to pay dividends or take other capital actions;

(23) the risk that we may not be able to identify suitable bank and non-bank acquisition opportunities as part of our growth strategy and even if we are able to identify attractive acquisition opportunities, we may not be able to complete such transactions on favorable terms or realize the anticipated benefits from such acquisitions;

(24) the risk that we could realize losses if we sell non-performing assets and the proceeds we receive are lower than the carrying value of such assets;

(25) risks related to regulatory approval to take certain actions, including any dividends on our common stock or preferred stock, any repurchases of common stock or any other issuance or redemption of any other regulatory capital instruments;

(26) the risk that our concentrated operations in the Southeastern U.S. make us vulnerable to local economic conditions, local weather catastrophes, public health issues, and other external events;

33

(27) the costs and effects of litigation, investigations or similar matters, or adverse facts and developments related thereto, including the costs and effects of litigation related to our participation in government stimulus programs associated with the COVID-19 pandemic;

(28) risks related to the fluctuation in our stock price and general volatility in the stock market;

(29) the effects of any damages to our reputation resulting from developments related to any of the items identified above; and

(30) other factors and other information contained in this Report and in other reports and filings that we make with the SEC under the Exchange Act, including, without limitation, those found in "Part II - Item 1A. Risk Factors" of this Report.

For a discussion of these and other risks that may cause actual results to differ from expectations, refer to “Part I - Item 1A. Risk Factors” and other information contained in Synovus' 2020 Form 10-K and our other periodic filings, including quarterly reports on Form 10-Q and current reports on Form 8-K, that we file from time to time with the SEC. All written or oral forward-looking statements that are made by or are attributable to Synovus are expressly qualified by this cautionary notice. You should not place undue reliance on any forward-looking statements since those statements speak only as of the date on which the statements are made. Synovus undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of new information or unanticipated events, except as may otherwise be required by law.

Executive Summary

Net income available to common shareholders for the first quarter of 2021 was $178.8 million, or $1.19 per diluted common share, a significant increase compared to $30.2 million, or $0.20 per diluted common share, in the first quarter of 2020. Adjusted net income per common share, diluted(1) was $1.21, compared to $0.21 for the first quarters of 2021 and 2020, respectively. The year-over-year increase was impacted by a significant provision for credit losses recorded during the first quarter of 2020 due to the onset of COVID-19 following the adoption of CECL on January 1, 2020.

Net interest income for the three months ended March 31, 2021 was $373.9 million, up $597 thousand compared to the same period in 2020 including $24.9 million in PPP processing fees during the first quarter of 2021. Net interest margin was down 33 bps over the comparable three-month period to 3.04%, due primarily to the decline in market interest rates and accelerated prepayment activity. On a sequential quarter basis, net interest income was down $12.1 million and net interest margin was down 8 bps. The sequential quarter decline in net interest income was primarily due to a lower day count and a continuation of low-rate pressure, partially offset by further declines in deposit pricing and continued deployment of excess liquidity. As we progress through the year, we expect to see increases in net interest income, excluding PPP fees, driven by loan growth, deployment of liquidity, a deceleration of prepayments, and further deposit cost reductions.

Non-interest revenue for the first quarter of 2021 was $111.0 million, up $7.1 million, or 7%, compared to the same period in 2020. Adjusted non-interest revenue(1), which excludes net investment securities gains/(losses) and increase/(decrease) in fair value of private equity investments, for the first quarter of 2021 was $112.9 million, up $13.6 million, or 14%, from the first quarter of 2020. Net mortgage banking income of $22.3 million remained strong and drove the year-over-year increase in non-interest revenue. While first quarter 2021 mortgage production levels remained elevated, the recent increase in interest rates is likely to reduce production levels going forward.

Non-interest expense for the first quarter of 2021 was $267.1 million, down $9.1 million, or 3%, compared to the first quarter of 2020 and adjusted non-interest expense(1) of $266.6 million was down $4.6 million, or 2%. The adjusted tangible efficiency ratio(1) for the first three months of 2021 was 54.19%, down 253 bps compared to the same period a year ago. We remain committed to prudent expense management, enabling us to continue investing in areas that position us for greater success, deliver a superior customer experience, and promote profitable growth.

At March 31, 2021, loans, net of deferred fees and costs, of $38.81 billion, increased $552.1 million, or 1%, from December 31, 2020 led by CRE growth of $208.2 million as the recovery of commercial real estate markets continued, C&I growth of $173.7 million driven by a $170.1 million increase in PPP loans, and consumer growth of $170.2 million primarily due to purchases of $607.0 million of third-party lending loans, including a $476.2 million prime auto portfolio purchase. These growth metrics were partially offset by declines in consumer mortgages and HELOCs of $214.3 million and $105.4 million, respectively, as consumers across the industry continued to use government stimulus to reduce revolving credit balances and deleverage.

At March 31, 2021, credit metrics remained stable with NPAs, NPLs, and past dues all near historical lows at Synovus, and net charge-offs remained low and declined $1.9 million on a sequential quarter basis to $20.2 million, or 21 basis points. Given elevated levels of liquidity and continued economic recovery, particularly in the Southeast, we are not expecting a significant change in net charge-offs in the near term. The ACL at March 31, 2021 totaled $614.7 million, a decrease of $38.8 million from December 31, 2020, resulting from the improved economic outlook and stable loan portfolio metrics that were partially offset by the increased size of the loan portfolio. The ACL to loans coverage ratio at March 31, 2021 was 1.58%, or 1.69% excluding PPP loans, and incorporates an outlook with moderate economic expansion and benefits from the recently approved government stimulus.

Total period-end deposits at March 31, 2021 increased $677.4 million, or 1%, compared to December 31, 2020. Core transaction deposits (non-interest bearing, NOW/savings, and money market deposits excluding public and brokered funds) increased $2.05 billion, or 6%, compared to December 31, 2020. The increase in deposit balances compared to December 31, 2020 is due largely to government stimulus programs including deposits associated with PPP loans.

At March 31, 2021, Synovus' CET1 ratio was 9.74%, well in excess of regulatory requirements including the capital conservation buffer of 2.5%, and was up 8 bps compared to December 31, 2020, driven by earnings. Synovus announced on January 26, 2021 that its Board of Directors authorized share repurchases of up to $200 million in 2021. During the first quarter of 2021, the Company did not complete any share repurchases. During the second quarter of 2021, Synovus had repurchased $23.2 million, or 499 thousand shares of its common stock, at an average price of $46.52 per share, as of May 5, 2021.

More detail on Synovus' financial results for the three months ended March 31, 2021 may be found in subsequent sections of "Item 2. – Management's Discussion and Analysis of Financial Condition and Results of Operations" of this Report. See also "Item 1A. - Risk Factors" of this Report.

Changes in Financial Condition

During the three months ended March 31, 2021, total assets increased $764.9 million from $54.39 billion at December 31, 2020 to $55.16 billion. Loans increased $552.1 million, including increases of $170.1 million in PPP loans net of unearned fees and a $476.2 million indirect auto portfolio purchase. Loans held for sale increased $233.8 million. Investment securities available for sale increased $863.3 million while cash and cash equivalents decreased $924.7 million.

The growth in assets was primarily funded by increases of $677.4 million in deposits. Securities sold under repurchase agreements increased $65.7 million. Total shareholders' equity at March 31, 2021 was flat, as compared to December 31, 2020, and included net income of $187.1 million and proceeds from stock option exercises of $12.6 million, offset by unrealized losses in investment securities available for sale and cash flow hedges of $121.0 million and $22.4 million, respectively, and dividends declared on common and preferred stock of $49.1 million and $8.3 million, respectively.

The loan to deposit ratio was 81.9% at both March 31, 2021 and December 31, 2020, compared to 96.1% at March 31, 2020.

At March 31, 2021, loans, net of deferred fees and costs, of $38.81 billion, increased $552.1 million, or 1%, from December 31, 2020 led by CRE growth of $208.2 million as the recovery of commercial real estate markets continued, C&I growth of $173.7 million driven by a $170.1 million increase in PPP loans, and consumer growth of $170.2 million primarily due to purchases of $607.0 million of third-party lending loans, including a $476.2 million prime auto loans purchase. These growth metrics were partially offset by declines in consumer mortgages and HELOCs of $214.3 million and $105.4 million, respectively, as consumers across the industry continued to use government stimulus to reduce revolving credit balances and deleverage. C&I loans remain the largest component of our loan portfolio, representing 50.7% of total loans, while CRE and consumer loans represent 27.1% and 22.2%, respectively. Our portfolio composition is established through a comprehensive concentration management policy which sets limits for C&I, CRE, and consumer loan levels as well as for sub-categories therein.

U.S. Small Business Administration Paycheck Protection Program (PPP)

Synovus is participating in the PPP, which is a loan program that originated from the CARES Act and was subsequently expanded by the Paycheck Protection Program and Health Care Enhancement Act, which was signed into law on April 24, 2020. Under the initial program, PPP loans are forgivable, in whole or in part, if the proceeds are used for payroll and other permitted purposes in accordance with the requirements of the PPP. These loans carry a fixed rate of 1.00% and a term of two years, if not forgiven, in whole or in part. The loans are guaranteed by the SBA. The SBA pays the originating bank a processing fee ranging from 1% to 5%, based on the size of the loan. Synovus began accepting applications from qualified customers on April 3, 2020 and provided nearly $2.9 billion in funding to close to 19,000 customers through the initial PPP, at

37

an average loan size of approximately $150 thousand. In the fourth quarter of 2020, Synovus began receiving first draw PPP loan forgiveness that totals $1.25 billion, or $1.20 billion net of unearned fees, life-to-date through March 31, 2021, including PPP loan forgiveness of $711 million, or $687 million net of unearned fees, during the first quarter of 2021.

On December 27, 2020, the Economic Aid to Hard-Hit Businesses, Nonprofits, and Venues Act was signed into law, and authorized the SBA to reopen the PPP for first draw loans, as well as guarantee second draw PPP loans of up to $2 million for certain eligible borrowers that previously received a PPP loan. These loans carry a fixed rate of 1.00% and a term of five years, if not forgiven, in whole or in part. The loans are guaranteed by the SBA. The SBA pays the originating bank a processing fee based on the size of the loan.

On March 11, 2021, the American Rescue Plan Act of 2021 was enacted which primarily expanded and clarified eligibility for first and second draw PPP loans and revised the exclusions from payroll costs for purposes of loan forgiveness.

Synovus began participating in the second phase of the PPP on January 19, 2021 with almost 10,000 applications submitted totaling $1.09 billion and total fundings of $894 million, or $857 million net of unearned fees, as of March 31, 2021. The total balance of PPP loans was $2.36 billion as of March 31, 2021, compared to $2.19 billion as of December 31, 2020.

Commercial Loans

Total commercial loans (which are comprised of C&I and CRE loans) at March 31, 2021 were $30.23 billion, or 77.9%, of the total loan portfolio, compared to $29.85 billion, or 78.0%, at December 31, 2020 and $28.29 billion, or 73.9%, at March 31, 2020.

At March 31, 2021, Synovus had eight commercial loan relationships with total commitments of $100 million or more (including amounts funded), with one single relationship exceeding $150 million in commitments.

Commercial and Industrial Loans

The C&I loan portfolio represents the largest category of Synovus' loan portfolio and is primarily comprised of general middle market and commercial banking clients across a wide range of industries. The following table shows the composition of the C&I loan portfolio aggregated by NAICS code. In accordance with Synovus' lending policy, each loan undergoes a detailed underwriting process which incorporates uniform underwriting standards and oversight in proportion to the size and complexity of the lending relationship. As of March 31, 2021, 82.5% (93.7% excluding PPP loans) of Synovus' C&I loans are secured by real estate, business equipment, inventory, and other types of collateral compared to 83.2% (93.8% excluding PPP loans) as of December 31, 2020. C&I loans grew $173.7 million, or 1%, from December 31, 2020, driven primarily by a $170.1 million increase in PPP loans at March 31, 2021.

(1)    Loan balance in each category expressed as a percentage of total C&I loans.

At March 31, 2021, $12.66 billion of C&I loans, or 32.6% of the total loan portfolio (including PPP loans of $2.36 billion), represented loans originated for the purpose of financing commercial, financial, and agricultural business activities. The primary source of repayment on these loans is revenue generated from products or services offered by the business or organization. The secondary source of repayment is the collateral, which consists primarily of equipment, inventory, accounts receivable, time deposits, cash surrender value of life insurance, and other business assets.

At March 31, 2021, $7.03 billion of C&I loans, or 18.1% of the total loan portfolio, represented loans originated for the purpose of financing owner-occupied properties. The financing of owner-occupied facilities is considered a C&I loan even though there is improved real estate as collateral. This treatment is a result of the credit decision process, which focuses on cash flow from operations of the business to repay the debt. The secondary source of repayment on these loans is the underlying real estate. These loans are predominately secured by owner-occupied and other real estate, and to a lesser extent, other types of collateral.

Commercial Real Estate Loans

CRE loans consist primarily of income-producing investment properties loans. Additionally, CRE loans include 1-4 family properties loans as well as land and development loans. Total CRE loans of $10.53 billion increased $208.2 million, or 2%, from December 31, 2020, driven primarily by growth in income-producing investment properties as the recovery of commercial real estate markets continues.

Investment properties loans consist of construction and mortgage loans for income-producing properties and are primarily made to finance multi-family properties, hotels, office buildings, shopping centers, warehouses and other commercial development properties. Total investment properties loans as of March 31, 2021 were $9.34 billion, or 88.6%, of the CRE loan portfolio, and increased $232.3 million, or 3%, from December 31, 2020 with most sub-categories experiencing growth other than warehouses, which were down $7.8 million, or 1%, from December 31, 2020.

1-4 Family Properties Loans

1-4 family properties loans include construction loans to home builders and commercial mortgage loans related to 1-4 family rental properties and are almost always secured by the underlying property being financed by such loans. These properties are primarily located in the markets served by Synovus. At March 31, 2021, 1-4 family properties loans totaled $639.0 million, or 6.1% of the CRE loan portfolio, and increased by $10.3 million, or 2%, from December 31, 2020.

39

Land and Development Loans

Land and development loans include commercial and residential development as well as land acquisition loans and are secured by land held for future development, typically in excess of one year. Properties securing these loans are substantially within markets served by Synovus and loan terms generally include personal guarantees from the principals. Loans in this portfolio are underwritten based on the LTV of the collateral and the capacity of the guarantor(s). Land and development loans of $559.2 million at March 31, 2021 decreased $34.4 million, or 6%, from $593.6 million at December 31, 2020.

Consumer Loans

The consumer loan portfolio consists of a wide variety of loan products offered through Synovus' banking network including first and second residential mortgages, HELOCs, and credit card loans, as well as home improvement, student, personal, and auto loans from third-party lending. The majority of Synovus' consumer loans are consumer mortgages and HELOCs secured by first and second liens on residential real estate primarily located in the markets served by Synovus. As of March 31, 2021, weighted-average FICO scores within the residential real estate portfolio based on committed balances were 790 for HELOCs and 773 for Consumer Mortgages.

Consumer loans at March 31, 2021 of $8.58 billion increased $170.2 million, or 2%, compared to December 31, 2020. Consumer mortgages decreased $214.3 million, or 4%, from December 31, 2020, and HELOCs decreased $105.4 million, or 7%, from December 31, 2020. Credit card loans of $267.4 million at March 31, 2021 decreased $13.6 million, or 5% from $281.0 million at December 31, 2020. The reductions in consumer mortgages, HELOCs, and credit card loans are primarily a result of consumers continuing to use government stimulus to reduce revolving credit balances and deleverage as well as the competitive low rate environment. Other consumer loans, which primarily includes third-party lending, increased $503.6 million, or 47%, from December 31, 2020. As of March 31, 2021, third-party lending balances totaled $1.18 billion, or 3.0%, of the total loan portfolio, and increased $503.2 million, or 74%, compared to December 31, 2020, led by purchases of $607.0 million of third-party lending loans, including a $476.2 million prime auto loans purchase. We believe that the risk-return profile, the 2-year average life, and the liquidity of the asset class is a good fit under current market conditions. We will continue to use third-party lending to manage the balance sheet, which could lead to increases in this portfolio.

Total period-end deposits at March 31, 2021 increased $677.4 million, or 1%, compared to December 31, 2020. Core transaction deposits increased $2.05 billion, or 6%, compared to December 31, 2020, due largely to government stimulus programs including deposits associated with the second phase of PPP loans. The sequential quarter growth in lower cost core transaction accounts of $2.05 billion included growth in non-interest-bearing demand deposits of $1.36 billion, money market accounts of $402.5 million, NOW accounts of $167.3 million, and savings balances of $120.8 million, and more than offset decreases of $391.2 million and $375.7 million in time deposits and brokered deposits, respectively, as well as declines of $605.7 million in public funds. Total deposit costs declined 6 bps during the first quarter of 2021, compared to the fourth quarter of 2020, due to repricing and remixing within the deposit portfolio.

On an average basis, the increase in total deposits was $480.9 million, or 1%, compared to the fourth quarter of 2020.

Non-interest Revenue

Non-interest revenue for the first quarter of 2021 was $111.0 million, up $7.1 million, or 7%, compared to the same period in 2020. Adjusted non-interest revenue, which excludes net investment securities gains/(losses) and increase/(decrease) in fair value of private equity investments, for the first quarter of 2021 was $112.9 million, up $13.6 million, or 14%, from the first quarter of 2020. Net mortgage banking income of $22.3 million remained strong and drove the year-over-year increase in non-interest revenue. While first quarter 2021 mortgage production levels remained elevated, the recent increase in interest rates is likely to reduce production levels going forward. See "Table 14 - Reconciliation of Non-GAAP Financial Measures” in this Report for applicable reconciliation to GAAP measures.

The following table shows the principal components of non-interest revenue.

Three Months Ended March 31, 2021 compared to March 31, 2020

Service charges on deposit accounts for the three months ended March 31, 2021 were down $656 thousand, or 3%, due largely to the impact of higher average balances as a result of stimulus funds. Service charges on deposit accounts consist of NSF fees, account analysis fees, and all other service charges. NSF fees were down $3.0 million, or 34%, for the three months ended March 31, 2021. Account analysis fees were up $2.2 million, or 32%, for the three months ended March 31, 2021, following our pricing for value initiative implemented during the first quarter of 2021 as part of Synovus Forward. All other service charges on deposit accounts, which consist primarily of monthly fees on retail demand deposits, saving accounts, and small business accounts, for the three months ended March 31, 2021, were up $132 thousand, or 3%.

Fiduciary and asset management fees are derived from providing estate administration, personal trust, corporate trust, corporate bond, investment management, financial planning, and family office services. Fiduciary and asset management fees increased $2.8 million, or 18%, for the three months ended March 31, 2021. The increases were driven by growth in total assets under management which increased by 35% year-over-year to $20.59 billion.

Card fees for the three months ended March 31, 2021 were up $1.0 million, or 10%, with increased transaction volume in all card fee categories. Card fees consist primarily of credit card interchange fees, debit card interchange fees, and merchant discounts. Card fees are reported net of certain associated expense items including customer loyalty program expenses and network expenses.

Brokerage revenue of $13.0 million for the three months ended March 31, 2021 was up $576 thousand, or 5%. The year-over-year increase was driven by growth in assets under management and higher transaction revenue driven by favorable

41

market conditions. Brokerage revenue consists primarily of brokerage commissions as well as advisory fees earned from the management of customer assets.

Mortgage banking income was significantly higher in the first three months of 2021, with an increase of $10.1 million compared to the three months ended March 31, 2020. Mortgage banking income was driven by higher production and sales, including an increase in refinance volume. Total secondary market mortgage loan production was $573.1 million, up $318.6 million, for the three months ended March 31, 2021. While first quarter 2021 mortgage production levels remained elevated, the recent increase in interest rates is likely to reduce production levels going forward.

Capital markets income primarily includes fee income from customer derivative transactions. Additionally, capital markets income includes fee income from capital raising investment banking transactions and foreign exchange as well as other miscellaneous income from capital market transactions. Capital markets income was $3.7 million lower for the three months ended March 31, 2021, as commercial client activity to lock in lower rates was elevated in 2020.

Income from BOLI, which includes increases in the cash surrender value of policies and proceeds from insurance benefits, increased $2.8 million, or 47%, for the three months ended March 31, 2021, due primarily to income on proceeds from insurance benefits. The first three months of 2021 included income on proceeds from insurance benefits of $2.1 million compared to $118 thousand in 2020.

Investment securities losses, net, of $2.0 million for the three months ended March 31, 2021 reflected strategic sales of mortgage-backed securities.

The main components of other non-interest revenue are fees for letters of credit and unused lines of credit, safe deposit box fees, access fees for ATM use, other service charges and loan servicing fees, income from insurance commissions, gains from sales of GGL/SBA loans, and other miscellaneous items. The three months ended March 31, 2021 included unrealized valuation gains of $3.5 million associated with deferred compensation and the three months ended March 31, 2020 included a sale-leaseback gain of $2.4 million.

Non-interest Expense

Non-interest expense for the first quarter of 2021 was $267.1 million, down $9.1 million, or 3%, compared to the first quarter of 2020 and adjusted non-interest expense of $266.6 million was down $4.6 million, or 2%. The adjusted tangible efficiency ratio for the first three months of 2021 was 54.19%, down 253 bps compared to the same period a year ago. We remain committed to prudent expense management, enabling us to continue investing in areas that position us for greater success, deliver a superior customer experience, and promote profitable growth. See "Table 14 - Reconciliation of Non-GAAP Financial Measures” in this Report for applicable reconciliation to GAAP measures.

The following table summarizes the components of non-interest expense.

Total non-interest expense	$	267,134	$	276,279	(3)	%

Three Months Ended March 31, 2021 compared to March 31, 2020

Salaries and other personnel expense increased $11.8 million, or 8%, for the three months ended March 31, 2021, due primarily to higher mortgage production-based commissions with commission expense up $2.3 million, higher share-based compensation expense of $4.1 million largely due to timing with higher level of retirement eligible expense acceleration, and valuation expense of $3.5 million associated with deferred compensation from higher market valuations (offset with unrealized valuation gains in other non-interest revenue). Total headcount of 5,175 declined 72 from December 31, 2020 and 253 from

42

March 31, 2020 led by Synovus' voluntary early retirement program offered during the fourth quarter of 2020 and branch closures.

Net occupancy, equipment, and software expense decreased $1.1 million, or 3%, during the three months ended March 31, 2021, due primarily to a reduction of 10 branches, as compared to December 31, 2019.

Third-party processing and other services includes all third-party core operating system and processing charges as well as third-party loan servicing charges. Third-party processing expense decreased $2.7 million, or 12%, for the three months ended March 31, 2021. The decline is primarily associated with Synovus' restructure of certain of its third-party consumer-based lending partnership arrangements during the second quarter of 2020 with a shift of new originations to held for sale and thereby reducing third-party loan servicing expense.

Professional fees decreased $1.6 million, or 15%, for the three months ended March 31, 2021, from decreases in consulting fees related to Synovus Forward, our revenue growth and efficiency initiatives.

FDIC insurance and other regulatory fees for the three months ended March 31, 2020 included the benefit of a $1.5 million reversal of estimated additional expense accrued during the fourth quarter of 2019.

During the three months ended March 31, 2021, Synovus recorded $531 thousand in restructuring charges primarily associated with two branch closures that will occur in April 2021 as part of Synovus Forward. During the three months ended March 31, 2020, Synovus recorded restructuring charges of $3.2 million from asset impairments, lease terminations, and severance related to seven branches closed in the first quarter of 2020.

Other operating expenses includes advertising, travel, insurance, network and communication, other taxes, subscriptions and dues, other loan and ORE expense, postage and freight, training, business development, supplies, donations, and other miscellaneous expenses. Other operating expenses were down $11.1 million for the three months ended March 31, 2021 driven by declines in most all expense categories including declines of $3.0 million in advertising and $1.3 million in travel.

Income Tax Expense

Income tax expense was $49.2 million for the three months ended March 31, 2021, representing an effective tax rate of 20.8%, compared to income tax expense of $3.6 million for the three months ended March 31, 2020, representing an effective tax rate of 8.5%. The effective tax rate for the three months ended March 31, 2021 is lower than the statutory tax rate primarily due to discrete benefits of $6.2 million related to changes in amounts taxable by jurisdictions and $1.8 million related to share-based compensation, partly offset by discrete expense of $4.1 million related to other accrual adjustments. The effective tax rate for the three months ended March 31, 2020 was lower than the statutory tax rate primarily due to a one-time discrete benefit of $2.7 million for the carryback of net operating loss deductions as permitted by the CARES Act, and $3.4 million of other discrete benefit items.

Synovus’ effective tax rate considers many factors including, but not limited to, the level of pre-tax income, BOLI, tax-exempt interest, certain income tax credits, and nondeductible expenses. In addition, the effective tax rate is affected by items that may occur in any given period but are not consistent from period-to-period, such as tax benefits related to share-based compensation, jurisdiction statutory tax rate changes, valuation allowance changes, and changes to unrecognized tax benefits. Accordingly, the comparability of the effective tax rate between periods may be impacted.

On March 31, 2021, the Biden Administration released the details of the Made in America Tax Plan which proposes an increase in the federal corporate income tax rate to 28%, up from the current 21%, among numerous other proposals. We continue to monitor the legislative process and the potential impact to the Company and its customers.

CREDIT QUALITY, CAPITAL RESOURCES AND LIQUIDITY

Credit Quality

Synovus continuously monitors the quality of its loan portfolio by industry, property type, geography, as well as credit quality metrics. At March 31, 2021, credit metrics remained stable with NPAs, NPLs, and past dues all near historical lows, and net charge-offs remained low and declined $1.9 million on a sequential quarter basis to $20.2 million, or 21 basis points. Given elevated levels of liquidity and continued economic recovery, particularly in the Southeast, we are not currently expecting a significant change in net charge-offs in the near term.

Non-performing Assets

Total NPAs as a percentage of total loans, ORE, and specific other assets were 0.50% at March 31, 2021, unchanged from both December 31, 2020 and March 31, 2020. Total NPAs were $195.6 million at March 31, 2021 compared to $192.1 million at December 31, 2020 and $190.0 million at March 31, 2020.

Criticized and Classified Loans

Our loan ratings are aligned to federal banking regulators' definitions of pass and criticized categories, which include special mention, substandard, doubtful, and loss. Substandard accruing and non-accruing loans, doubtful, and loss loans are often collectively referred to as classified. Special mention, substandard, doubtful, and loss loans are often collectively referred to as criticized and classified loans. The following table presents a summary of criticized and classified loans. The increase in criticized and classified loans at March 31, 2021 compared to December 31, 2020 was primarily hospitality-related with increases in special mention and substandard accruing loans in the hotel and full-service restaurant industry as a result of COVID-19. We expect the levels of criticized and classified loans to decline as borrowers' reported financial statements begin to reflect the current monthly improvement we are seeing in borrowers' cash flows.

Provision for Credit Losses and Allowance for Credit Losses

Provision for credit losses includes the provisions for loan losses and unfunded commitments. The reversal of provision for credit losses of $18.6 million for the three months ended March 31, 2021 included net charge-offs of $20.2 million and resulted from the improved economic outlook and stable loan portfolio metrics that were partially offset by the increased size of the loan portfolio including $15.2 million in reserves added as result of purchases of $607.0 million of third-party lending loans, including a $476.2 million prime auto purchase. The ACL at March 31, 2021 totaled $614.7 million consisting of an ALL of $563.2 million and reserve for unfunded commitments of $51.5 million, resulting in an ACL to loans coverage ratio of 1.58% and an ACL to NPLs ratio of 396%. Excluding PPP loans, the ACL to loans coverage ratio was 1.69%. The ACL at March 31, 2021 incorporates an outlook with moderate economic expansion and benefits from the estimated impact of government stimulus.

Troubled Debt Restructurings

Accruing TDRs were $129.8 million at March 31, 2021, compared to $135.0 million at December 31, 2020 and $160.1 million at March 31, 2020. Accruing TDRs decreased $5.2 million from December 31, 2020 and $30.4 million from March 31, 2020. Non-accruing TDRs were $36.1 million at March 31, 2021, compared to $39.0 million at December 31, 2020 and $12.8 million at March 31, 2020.

Accruing TDRs are considered performing because they are performing in accordance with the restructured terms. At March 31, 2021, December 31, 2020, and March 31, 2020, approximately 99%, 99%, and 98%, respectively, of accruing TDRs were current. In addition, subsequent defaults on accruing TDRs (defaults defined as the earlier of the TDR being placed on non-accrual status or reaching 90 days past due with respect to principal and/or interest payments within twelve months of the TDR designation) have continued to remain at low levels.

Non-TDR Modifications due to COVID-19

Regulatory agencies have encouraged financial institutions to work prudently with borrowers who are or may be unable to meet their contractual payment obligations because of COVID-19. In the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (initially issued on March 22, 2020 and revised on April 7, 2020), for example, the regulatory agencies expressed their view of loan modification programs as positive actions that may mitigate adverse effects on borrowers due to COVID-19 and their unwillingness to criticize institutions for working with borrowers in a safe and sound manner. Moreover, the Interagency Statement provided that eligible loan modifications related to COVID-19 may be accounted for under section 4013 of the CARES Act or in accordance with ASC 310-40. On December 27, 2020, the Consolidated Appropriations Act, 2021 extended the applicable period of Section 4013 of the CARES Act. This allows banks to elect to not consider loan modifications related to COVID-19 that are made between March 1, 2020 and the earlier of January 1, 2022, or 60 days after the national emergency ends to borrowers that are current (i.e., less than 30 days past due as of December 31, 2019) as TDRs. The regulatory agencies further stated that performing loans granted payment deferrals due to COVID-19 are not considered past due or non-accrual. FASB confirmed the foregoing regulatory agencies' view that such short-term modifications (e.g., six months) made on a good-faith basis in response to COVID-19 for borrowers who are current are not TDRs.

45

During 2020, Synovus provided relief programs consisting primarily of 90-day payment deferral relief to borrowers negatively impacted by COVID-19, and as of March 31, 2021, 0.2% of the total loan portfolio was in a P&I deferral status as compared to 0.3% of the total loan portfolio at December 31, 2020. In addition to our P&I deferment program, under the CARES Act, we have also provided borrowers who have been impacted by COVID-19 with other modifications such as interest only relief or amortization extensions on approximately 2% of total loans, at both March 31, 2021 and December 31, 2020.

Capital Resources

Synovus and Synovus Bank are required to comply with capital adequacy standards established by our primary federal regulator, the Federal Reserve. Synovus and Synovus Bank measure capital adequacy using the standardized approach under Basel III. At March 31, 2021, Synovus and Synovus Bank's capital levels remained strong and exceeded well-capitalized requirements currently in effect. The following table presents certain ratios used to measure Synovus and Synovus Bank's capitalization.

At March 31, 2021, Synovus' CET1 ratio increased to 9.74%, well in excess of regulatory requirements including the capital conservation buffer of 2.5%. The March 31, 2021 CET1 ratio improved 8 bps compared to December 31, 2020 driven by earnings. For additional information on regulatory capital requirements, see "Part II - Item 8. Financial Statements and Supplementary Data - Note 12 - Regulatory Capital" to the consolidated financial statements of Synovus' 2020 Form 10-K. Management reviews the Company's capital position on an on-going basis and believes, based on internal capital analyses and earnings projections, that Synovus is well positioned to meet relevant regulatory capital standards.

Synovus announced on January 26, 2021 that its Board of Directors authorized share repurchases of up to $200 million in 2021. During the first quarter of 2021, the Company did not complete any share repurchases. During the second quarter of 2021, Synovus had repurchased $23.2 million, or 499 thousand shares of its common stock, at an average price of $46.52 per share, as of May 5, 2021.

On August 26, 2020, the federal banking regulators issued a final rule (following an interim final rule issued on March 27, 2020) that allowed electing banking organizations that adopt CECL during 2020 to mitigate the estimated effects of CECL on

46

regulatory capital for two years, followed by a three-year phase-in transition period. Synovus adopted CECL on January 1, 2020 and the March 31, 2021 regulatory capital ratios reflect Synovus' election of the five-year transition provision. At March 31, 2021, $84 million, or a cumulative 20 basis points benefit to CET1, was deferred.

Dividends

Synovus has historically paid a quarterly cash dividend to the holders of its common stock. Management and the Board of Directors closely monitor current and projected capital levels, liquidity (including dividends from subsidiaries), financial markets and other economic trends, as well as regulatory requirements regarding the payment of dividends.

Synovus' ability to pay dividends on its common stock and preferred stock is primarily dependent upon dividends and distributions that it receives from its bank and non-banking subsidiaries, which are restricted by various regulations administered by federal and state bank regulatory authorities.

Synovus declared common stock dividends of $49.1 million, or $0.33 per common share, for the three months ended March 31, 2021, compared to $48.6 million, or $0.33 per common share, for the three months ended March 31, 2020. In addition, Synovus declared dividends on its preferred stock of $8.3 million during both the three months ended March 31, 2021 and 2020.

Liquidity

Liquidity represents the extent to which Synovus has readily available sources of funding to meet the needs of depositors, borrowers and creditors, to support asset growth, and to otherwise sustain operations of Synovus and its subsidiaries, at a reasonable cost, on a timely basis, and without adverse consequences. ALCO monitors Synovus' economic, competitive, and regulatory environment and is responsible for measuring, monitoring, and reporting on liquidity and funding risk as well as market risk.

In accordance with Synovus policies and regulatory guidance, ALCO evaluates contractual and anticipated cash flows under normal and stressed conditions to properly manage the Company’s liquidity profile. Synovus places an emphasis on maintaining numerous sources of current and contingent liquidity to meet its obligations to depositors, borrowers, and creditors on a timely basis. Liquidity is generated through various sources, including, but not limited to, maturities and repayments of loans by customers, maturities and sales of investment securities, and growth in core or wholesale deposits. Management continuously monitors and maintains appropriate levels of liquidity so as to provide adequate funding sources to manage customer deposit withdrawals, loan requests, and other funding demands.

Synovus Bank also generates liquidity through the issuance of brokered certificates of deposit and money market accounts. Synovus Bank accesses these funds from a broad geographic base to diversify its sources of funding and liquidity. Synovus Bank also has the capacity to access funding through its membership in the FHLB system and through the Federal Reserve discount window. At March 31, 2021, based on currently pledged collateral, Synovus Bank had access to incremental FHLB funding of $6.38 billion, subject to FHLB credit policies.

In addition to bank level liquidity management, Synovus must manage liquidity at the parent company level for various operating needs including the servicing of debt, the payment of dividends on our common stock and preferred stock, share repurchases, payment of general corporate expenses and potential capital infusions into subsidiaries. The primary source of liquidity for Synovus consists of dividends from Synovus Bank, which is governed by certain rules and regulations of the GA DBF and the Federal Reserve Bank. Synovus' ability to receive dividends from Synovus Bank in future periods will depend on a number of factors, including, without limitation, Synovus Bank's future profits, asset quality, liquidity, and overall condition. In addition, both the GA DBF and Federal Reserve Bank may require approval to pay dividends, based on certain regulatory statutes and limitations.

Synovus presently believes that the sources of liquidity discussed above, including existing liquid funds on hand, are sufficient to meet its anticipated funding needs. However, if economic conditions were to significantly deteriorate, regulatory capital requirements for Synovus or Synovus Bank were to increase as the result of regulatory directives or otherwise, or Synovus believes it is prudent to enhance current liquidity levels, then Synovus may seek additional liquidity from external sources. See "Part I – Item 1A. Risk Factors - Changes in the cost and availability of funding due to changes in the deposit market and credit market may adversely affect our capital resources, liquidity and financial results" of Synovus' 2020 Form 10-K. Furthermore, Synovus may, from time to time, take advantage of attractive market opportunities to refinance its existing debt, redeem its preferred stock, or strengthen its liquidity or capital position.

Earning Assets and Sources of Funds

Average total assets for the three months ended March 31, 2021 increased $5.49 billion, or 11%, to $54.19 billion as compared to $48.70 billion for the first three months of 2020. Average earning assets increased $5.02 billion, or 11%, in the first three months of 2021 compared to the same period in 2020 and represented 92.2% of average total assets at March 31, 2021, as compared to 92.3% at March 31, 2020. The increase in average earning assets primarily resulted from a $2.16 billion increase in average interest-bearing funds held at the Federal Reserve Bank, a $1.76 billion increase in average investment securities available for sale, an $821.3 million increase in loans held for sale, and a $619.2 million, or 2%, increase in average total loans, net of unearned, which included average PPP loans of $2.24 billion.

Average interest-bearing liabilities increased $567.9 million, or 2%, to $34.08 billion for the first three months of 2021 compared to the same period in 2020. The increase in average interest-bearing liabilities resulted from a $4.37 billion, or 34%, increase in average money market deposits (includes an increase of $573.9 million in average other brokered deposits) and a $2.12 billion, or 33%, increase in average interest-bearing demand deposits. These increases were partially offset by a $3.41 billion, or 38%, decrease in average time deposits (includes a decrease of $747.7 million in brokered time deposits) a $1.48 billion decrease in average long-term debt, including redemption of $250.0 million in subordinated debt in the fourth quarter of 2020, and a $1.38 billion decrease in other short-term borrowings. Average non-interest-bearing demand deposits increased $4.38 billion, or 47%, to $13.79 billion for the first three months of 2021 compared to the same period in 2020, due largely to liquidity associated with PPP lending.

Net interest income for the three months ended March 31, 2021 was $373.9 million, up $597 thousand compared to the same period in 2020 including $24.9 million in PPP processing fees during the first quarter of 2021. Net interest margin was down 33 bps over the comparable three-month period to 3.04%, due primarily to the decline in market interest rates and accelerated prepayment activity. For the three months ended March 31, 2021, the yield on earning assets was 3.32%, a decrease of 101 bps compared to the three months ended March 31, 2020, while the effective cost of funds decreased 68 bps to 0.28%. The yield on loans decreased 60 bps to 4.02% while the yield on investment securities decreased 169 bps to 1.40% over the three months ended March 31, 2020.

On a sequential quarter basis, net interest income was down $12.1 million and net interest margin for the first quarter was 3.04%, which was down 8 bps compared to the fourth quarter of 2020. The sequential quarter decline in net interest income was primarily due to a lower day count and a continuation of low-rate pressure, partially offset by further declines in deposit pricing and continued deployment of excess liquidity. The first quarter of 2021 included average PPP loan balances of $2.24 billion versus $2.55 billion in the fourth quarter of 2020 and $24.9 million recognized for associated PPP processing fees versus $24.8 million in the fourth quarter of 2020. For the first quarter of 2021, the yield on earning assets decreased 17 bps, while the effective cost of funds decreased 9 bps compared to the fourth quarter of 2020.

As we progress through the year, we expect to see increases in net interest income, excluding PPP fees, driven by loan growth, deployment of liquidity, a deceleration of prepayments, and further deposit cost reductions.

Market Risk Analysis

Interest rate risk is the primary market risk to which Synovus is potentially exposed. Synovus measures its sensitivity to changes in market interest rates through the use of a simulation model which incorporates all of Synovus’ earning assets and liabilities. These simulations are used to determine a baseline net interest income projection and the sensitivity of the income profile based on changes in interest rates. These simulations incorporate assumptions and factors, including, but not limited to, changes in market rates, in the size or composition of the balance sheet, and in repricing characteristics as well as customer behaviors. This process is reviewed and updated on an on-going basis in a manner consistent with Synovus’ ALCO governance framework.

Synovus has modeled its baseline net interest income projection assuming a flat interest rate environment with the federal funds rate at the Federal Reserve’s current targeted range of 0% to 0.25% and the current prime rate of 3.25%. Synovus has modeled the impact of a gradual increase in market interest rates across the yield curve of 100 and 200 bps and a gradual decline of 25 bps to determine the sensitivity of net interest income for the next twelve months. The lesser decline of the downrate scenario presented was selected in light of the low absolute level of monetary policy rates and generally incorporates an assumption that rates are floored at the zero-lower-bound. Synovus' current rate risk position is considered asset-sensitive and would be expected to benefit net interest income in a rising interest rate environment and reduce net interest income in a declining interest rate environment. The decline in sensitivity relative to the prior period-end is the result of a host of factors, including a reduction in reserve balances held with the Federal Reserve and the higher absolute level of long-term interest rates. The following table represents the estimated sensitivity of net interest income at March 31, 2021, with comparable information for December 31, 2020.

Table 13 - Twelve Month Net Interest Income Sensitivity
	Estimated % Change in Net Interest Income as Compared to Unchanged Rates (for the next twelve months)
Change in Short-term Interest Rates (in bps)	March 31, 2021	December 31, 2020
+200	4.9%	6.8%
+100	2.4%	3.5%
Flat	—%	—%
-25	(0.3)%	(0.5)%

The net interest income simulation model is the primary tool utilized to evaluate potential interest rate risks over a shorter-term time horizon. Synovus also evaluates potential longer-term interest rate risk through modeling and evaluation of the sensitivity of the Company's Economic Value of Equity (EVE). The EVE measurement process estimates the net fair value of assets, liabilities, and off-balance sheet financial instruments under various interest rate scenarios. Management uses EVE sensitivity analyses as an additional means of measuring interest rate risk and incorporates this form of analysis within its governance and limits framework.

LIBOR Transition

In July 2017, the Financial Conduct Authority (FCA), which regulates LIBOR, announced that it intends to stop persuading or compelling banks to submit rates for the calculation of LIBOR at the end of 2021. On March 5, 2021, the FCA confirmed that all LIBOR settings will either cease to be provided by any administrator or no longer be representative immediately after December 31, 2021 for the 1-week and 2-month US dollar settings and immediately after June 30, 2023 for all remaining US dollar settings.

The ARRC has proposed SOFR as its preferred rate as an alternative to LIBOR and has proposed a paced market transition plan to SOFR from LIBOR. Organizations are currently working on industry-wide and company-specific transition plans related to derivatives and cash markets exposed to LIBOR. As noted within "Part I - Item 1A. Risk Factors" of Synovus' 2020 Form 10-K, Synovus holds instruments that may be impacted by the discontinuance of LIBOR including floating rate obligations, loans, deposits, derivatives and hedges, and other financial instruments but is not able to currently predict the associated financial impact of the transition to an alternative reference rate. Synovus has established a cross-functional LIBOR transition working group that has 1) assessed the Company's current exposure to LIBOR indexed instruments and the data, systems and processes that will be impacted; 2) established a detailed implementation plan; and 3) developed a formal governance structure for the transition.

Critical Accounting Policies

The accounting and financial reporting policies of Synovus are in accordance with GAAP and conform to the accounting and reporting guidelines prescribed by bank regulatory authorities. Synovus has identified certain of its accounting policies as “critical accounting policies,” consisting of those related to the allowance for credit losses and income taxes. In determining which accounting policies are critical in nature, Synovus has identified the policies that require significant judgment or involve complex estimates. It is management's practice to discuss critical accounting policies with the Board of Directors' Audit Committee on a periodic basis, including the development, selection, implementation and disclosure of the critical accounting policies. The application of these policies has a significant impact on Synovus’ unaudited interim consolidated financial statements. Synovus’ financial results could differ significantly if different judgments or estimates are used in the application of these policies. All accounting policies described in "Part II - Item 8. Financial Statements and Supplementary Data - Note 1 - Summary of Significant Accounting Policies" in Synovus' 2020 Form 10-K should be reviewed for a greater understanding of how we record and report our financial performance. There have been no significant changes to the accounting policies, estimates and assumptions, or the judgments affecting the application of these estimates and assumptions from those disclosed in Synovus' 2020 Form 10-K other than the exclusion of goodwill impairment as a critical accounting estimate due to lack of impairment indicators.

Non-GAAP Financial Measures

The measures entitled adjusted non-interest revenue; adjusted non-interest expense; adjusted total revenue; adjusted tangible efficiency ratio; adjusted net income per common share, diluted; adjusted return on average assets; adjusted return on average common equity; adjusted return on average tangible common equity; and tangible common equity ratio are not measures recognized under GAAP and therefore are considered non-GAAP financial measures. The most comparable GAAP measures to these measures are total non-interest revenue; total non-interest expense; total FTE revenue; efficiency ratio-FTE; net income per common share, diluted; return on average assets; return on average common equity; and the ratio of total shareholders' equity to total assets, respectively.

Management believes that these non-GAAP financial measures provide meaningful additional information about Synovus to assist management and investors in evaluating Synovus’ operating results, financial strength, the performance of its business, and the strength of its capital position. However, these non-GAAP financial measures have inherent limitations as analytical tools and should not be considered in isolation or as a substitute for analyses of operating results or capital position as reported under GAAP. The non-GAAP financial measures should be considered as additional views of the way our financial measures are affected by significant items and other factors, and since they are not required to be uniformly applied, they may not be comparable to other similarly titled measures at other companies. Adjusted total revenue and adjusted non-interest revenue are measures used by management to evaluate total FTE revenue and non-interest revenue exclusive of net investment securities gains (losses) and changes in fair value of private equity investments, net. Adjusted non-interest expense and the adjusted tangible efficiency ratio are measures utilized by management to measure the success of expense management initiatives focused on reducing recurring controllable operating costs. Adjusted net income per common share, diluted, adjusted return on average assets, and adjusted return on average common equity are measurements used by management to evaluate operating results exclusive of items that management believes are not indicative of ongoing operations and impact period-to-period comparisons. Adjusted return on average tangible common equity is a measure used by management to compare Synovus' performance with other financial institutions because it calculates the return available to common shareholders without the impact of intangible assets and their related amortization, thereby allowing management to evaluate the performance of the business consistently. The tangible common equity ratio is used by management to assess the strength of our capital position. The computations of these measures are set forth in the tables below.

(b)    The maximum number of Shares of the Share Authorization that may be issued pursuant to ISOs under this Plan shall be 5,500,000.

(c)    Subject to adjustment in Section 4.4, no Nonemployee Director may be granted Awards that have a grant date fair value of more than $350,000 (as determined in a accordance with applicable accounting standards) in any Plan Year, except that this limit on Nonemployee Director Awards shall be increased $500,000 for any Nonemployee Director serving as Chairman of the Board.

4.2    Share Usage. Shares covered by an Award shall only be counted as used to the extent they are actually issued. Any Shares related to Awards which terminate by expiration, forfeiture, cancellation, or otherwise without the issuance of such Shares, are settled in cash in lieu of Shares, or are exchanged with the Committee’s permission, prior to the issuance of Shares, for Awards not involving Shares, shall be available again for grant under this Plan and shall not count against the Share Authorization. However, the full number of Stock Appreciation Rights granted that are to be settled by the issuance of Shares shall be counted against the number of Shares available for award under the Plan, regardless of the number of Shares actually issued upon settlement of such Stock Appreciation Rights. Further, any Shares withheld to satisfy tax withholding obligations on Awards issued under the Plan, Shares tendered to pay the Option Price of Options, and Shares repurchased on the open market with the proceeds of an Option

exercise will no longer be eligible to be returned as available Shares under the Plan. The Shares available for issuance under this Plan may be authorized and unissued Shares or treasury Shares.

4.3    Adjustments in Authorized Shares. In the event of any corporate event or transaction (including, but not limited to, a change in the Shares of the Company or the capitalization of the Company) such as a merger, consolidation, reorganization, recapitalization, separation, partial or complete liquidation, stock dividend, stock split, reverse stock split, split up, spin-off, or other distribution of stock or property of the Company, combination of Shares, exchange of Shares, dividend in-kind, or other like change in capital structure, number of outstanding Shares or distribution (other than normal cash dividends) to shareholders of the Company, or any similar corporate event or transaction, the Committee, in order to prevent dilution or enlargement of Participants’ rights under this Plan, shall substitute or adjust the number and kind of Shares that may be issued under this Plan or under particular forms of Awards, the number and kind of Shares subject to outstanding Awards, the Option Price or Grant Price applicable to outstanding Awards, the Annual Award Limits, or other value determinations applicable to outstanding Awards, with the specific adjustments to be determined by the Committee in its sole discretion.

The Committee shall make appropriate adjustments to any other terms of any outstanding Awards under this Plan to reflect such changes or distributions, including modifications of performance goals and changes in the length of Performance Periods. The determination of the Committee as to the foregoing adjustments, if any, shall be conclusive and binding on Participants under this Plan.

Subject to the provisions of Article 16 and notwithstanding anything else herein to the contrary, without affecting the number of Shares reserved or available hereunder, the Committee may authorize the issuance or assumption of benefits under this Plan in connection with any merger, consolidation, acquisition of property or stock, or reorganization upon such terms and conditions as it may deem appropriate (including, but not limited to, a conversion of equity awards into Awards under this Plan in a manner consistent with Accounting Standards Codification (ASC) 718 Section 55).

Any actions taken under this Section 4.4 shall be subject to compliance with the rules under Code Sections 409A, 422 and 424, as and where applicable.

4.4    Minimum Vesting Requirements. Except with respect to a maximum of five percent (5%) of the Share Authorization, any stock-based Awards which vest on the basis of a Participant’s continued employment with or provision of service to the Company shall have a minimum vesting requirement of one (1) year and any stock-based Awards which vest upon the attainment of performance goals shall provide for a Performance Period of at least one (1) year.

Options granted under this Article 6 shall be exercised by the delivery of a notice of exercise to the Company or an agent designated by the Company in a form specified or accepted by the Committee setting forth the number of Shares with respect to which the Option is to be exercised, accompanied by full payment for the Shares, or by complying with any alternative exercise procedures the Committee may authorize.

The Option Price of any Option shall be payable to the Company in full either: (a) in cash or its equivalent; (b) by tendering (either by actual delivery or attestation) previously acquired Shares having an aggregate Fair Market Value at the time of exercise equal to the Option Price; (c) by a cashless (broker-assisted) exercise; (d) by having the Company withhold Shares having a Fair Market Value on the date of exercise equal to the Option Price; (e) by a combination of (a), (b), (c) and/or (d); or (f) any other method approved or accepted by the Committee in its sole discretion.

Subject to any governing rules or regulations, as soon as practicable after receipt of written notification of exercise and full payment (including satisfaction of any applicable tax withholding), the Company shall deliver to the Participant evidence of book entry Shares, or upon the Participant’s request, Share certificates in an appropriate amount based upon the number of Shares purchased under the Option(s).

Unless otherwise determined by the Committee, all payments under all of the methods indicated above shall be paid in United States dollars.

Each Participant’s Award Agreement shall set forth the extent to which the Participant shall have the right to exercise the Option following termination of the Participant’s employment or provision of services to the Company, its Affiliates, and/or its Subsidiaries, as the case may be. Such provisions shall be determined in the sole discretion of the Committee, shall be included in the Award Agreement entered into with each Participant, need

not be uniform among all Options issued pursuant to this Article 6, and may reflect distinctions based on the reasons for termination.

6.9    No Deferral Feature. No Option shall provide for any feature for the deferral of compensation other than the deferral of recognition of income until the exercise or disposition of the Option.

6.10    No Dividend Equivalents. No Option shall provide for dividend equivalents.

Article 7.    Stock Appreciation Rights                                

7.1    Grant of SARs. Subject to the terms and conditions of this Plan, SARs may be granted to Participants at any time and from time to time as shall be determined by the Committee.

Subject to the terms and conditions of this Plan, the Committee shall have complete discretion in determining the number of SARs granted to each Participant and, consistent with the provisions of this Plan, in determining the terms and conditions pertaining to such SARs.

(b)    The number of Shares with respect to which the SAR is exercised.

At the discretion of the Committee, the payment upon SAR exercise may be in cash, Shares, or any combination thereof, or in any other manner approved by the Committee in its sole discretion. The Committee’s determination regarding the form of SAR payout shall be set forth in the Award Agreement pertaining to the grant of the SAR.

7.6    Termination of Employment/Service. Each Award Agreement shall set forth the extent to which the Participant shall have the right to exercise the SAR following termination of the Participant’s employment with or provision of services to the Company, its Affiliates, and/or its Subsidiaries, as the case may be.

The dividends or dividend equivalents may

be subject to any limitations and/or restrictions determined by the Committee, and shall in all cases be paid in a manner that complies with the restrictions under Code Section 409A.

Article 14.    Change of Control                                    

Notwithstanding any other provision of the Plan to the contrary, unless the Committee specifies otherwise in an Award Agreement, in the event of a Change of Control in which the surviving entity does not assume or otherwise equitably convert or substitute Awards in a manner approved by the Committee or the Board: (i) any Options and Stock Appreciation Rights which are outstanding immediately prior to the effective date such Change of Control, and which are not then exercisable and vested, shall become fully exercisable and vested to the full extent of the original grant; (ii) the restrictions and deferral limitations applicable to any Restricted Stock shall lapse, and such Restricted Stock shall become free of all restrictions and limitations and become fully vested and transferable to the full extent of the original grant; and (iii) the restrictions and deferral limitations and other conditions applicable to any other Awards under the Plan shall lapse, and such other Awards shall become free of all restrictions, limitations or conditions and become fully vested and transferable to the full extent of the original grant. Performance Shares or Performance Units that were outstanding immediately prior to effective time of the Change of Control shall be determined and deemed to have been earned as of the date of the Change of Control based upon (A) an assumed achievement of all relevant performance goals at the “target” level if the Change of Control occurs during the first half of the applicable performance period, or (B) the actual level of achievement of all relevant performance goals against target (measured as of the end of the calendar quarter immediately preceding the date of the Change of Control), if the Change of Control occurs during the second half of the applicable performance period, and, in either such case, there shall be a prorata payout to such Participant within sixty (60) days following the Change of Control (unless a later date is required by Section 19.14 hereof), based upon the length of time within the performance period that has elapsed prior to the date of the Change of Control.

Notwithstanding the foregoing provisions of this Article 14, with respect to Awards granted under this Plan which are assumed by the surviving entity in a Change of Control transaction, or are equitably converted or substituted in connection with a Change of Control, in either case in a manner approved by the Committee or the Board, the vesting of such Awards shall not be accelerated unless the Participant’s employment is terminated within two years following the effective date of such Change of Control either (i) by the surviving entity without cause or (ii) by the Participant for good reason. With regard to each Award, a Participant shall not be considered to have been terminated without Cause or to have resigned for Good Reason unless either (i) the Award Agreement includes such provision or (ii) the Participant is party to an employment, severance or similar agreement with the Company or an Affiliate that includes provisions regarding termination without cause or in which the Participant is permitted to resign for good reason.

Article 15.    Rights of Participants

Nothing in this Plan or an Award Agreement shall interfere with or limit in any way the right of the Company, its Affiliates, and/or its Subsidiaries to terminate any Participant’s employment or service on the Board or to the Company at any time or for any reason not prohibited by law, nor confer upon any Participant any right to continue his employment or service as a Director for any specified period of time.

Neither an Award nor any benefits arising under this Plan shall constitute an employment contract with the Company, its Affiliates, and/or its Subsidiaries and, accordingly, subject to Articles 3 and 17, this Plan and the benefits hereunder may be terminated at any time in the sole and exclusive discretion of the Committee without giving rise to any liability on the part of the Company, its Affiliates, and/or its Subsidiaries.

16.2    Adjustment of Awards Upon the Occurrence of Certain Unusual or Nonrecurring Events. The Committee shall make adjustments in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events, other than those described in Section 4.4 hereof, affecting the Company or the financial statements of the Company or of changes in applicable laws, regulations, or accounting principles, whenever the Committee determines that such adjustments are appropriate in order to prevent unintended dilution or enlargement of the benefits or potential benefits intended to be made available under this Plan. The Committee shall determine any adjustment after taking into account, to the extent applicable, the provisions of the Code applicable to Incentive Stock Options and the provisions of Section 409A of the Code. The determination of the Committee as to the foregoing adjustments, if any, shall be conclusive and binding on Participants under this Plan.

16.3    Awards Previously Granted.

With respect to withholding required upon the exercise of Options or SARs, upon the lapse of restrictions on Restricted Stock and Restricted Stock Units, or upon the achievement of performance goals related to Performance Shares, or any other taxable event arising as a result of an Award granted hereunder, the withholding requirement may be satisfied, in whole or in part, by having the Company withhold Shares having a Fair Market Value on the date the tax is to be determined equal to the amount required to be withheld in accordance with applicable tax requirements (up to the maximum individual statutory rate in the applicable jurisdiction as may be permitted under then-current accounting principles to qualify for equity classification). All such elections shall be irrevocable, made in writing, and signed by the Participant, and shall be subject to any restrictions or limitations that the Committee, in its sole discretion, deems appropriate.

Article 18.    Successors                                        

All obligations of the Company under this Plan with respect to Awards granted hereunder shall be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company.

Article 19.    General Provisions                                    

19.1    Forfeiture Events.

In addition, the Committee may specify in an Award Agreement that the Participant’s rights, payments, and benefits with respect to an Award shall be subject to reduction, cancellation, forfeiture, or recoupment upon the occurrence of certain specified events, in addition to any otherwise applicable vesting or performance conditions of an Award. Such events may include, but shall not be limited to, termination of employment for cause, termination of the Participant’s provision of services to the Company, Affiliate, and/or Subsidiary, violation of material Company, Affiliate, and/or Subsidiary policies, breach of noncompetition, confidentiality, or other restrictive covenants that may apply to the Participant, or other conduct by the Participant that is detrimental to the business or reputation of the Company, its Affiliates, and/or its Subsidiaries.

(b)    Notwithstanding any other provisions in this Plan, any Award which is subject to recovery under any law, government regulation or stock exchange listing requirement will be subject to such deductions and clawback as may be required to be made pursuant to such law, government regulation or stock exchange listing requirement (or any policy adopted by the Company pursuant to any such law, government regulation or stock exchange listing requirement) and the Committee, in its sole and exclusive discretion, may require that any Participant reimburse the Company all or part of the amount of any payment in settlement of any Award granted hereunder.

19.2    Legend. The certificates for Shares may include any legend that the Committee deems appropriate to reflect any restrictions on transfer of such Shares.

19.3    Gender and Number. Except where otherwise indicated by the context, any masculine term used herein also shall include the feminine, the plural shall include the singular, and the singular shall include the plural.

19.4    Severability. In the event any provision of this Plan shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of this Plan, and this Plan shall be construed and enforced as if the illegal or invalid provision had not been included.

19.5    Requirements of Law. The granting of Awards and the issuance of Shares under this Plan shall be subject to all applicable laws, rules, and regulations, and to such approvals by any governmental agencies, the NYSE or other national securities exchanges as may be required.

19.6    Delivery of Title. The Company shall have no obligation to issue or deliver evidence of title for Shares issued under this Plan prior to:

(a)    Obtaining any approvals from governmental agencies that the Company determines are necessary or advisable; and

(b)    Completion of any registration or other qualification of the Shares under any applicable national or foreign law or ruling of any governmental body that the Company determines to be necessary or advisable.

19.7    Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

19.8    Investment Representations. The Committee may require any individual receiving Shares pursuant to an Award under this Plan to represent and warrant in writing that the individual is acquiring the Shares for investment and without any present intention to sell or distribute such Shares.

19.9    Employees Based Outside of the United States. Notwithstanding any provision of this Plan to the contrary, in order to comply with the laws in other countries in which the Company, its Affiliates, and/or its Subsidiaries operate or have Employees or Directors, the Committee, in its sole discretion, shall have the power and authority to:

(a)    Determine which Affiliates and Subsidiaries shall be covered by this Plan.

(b)    Determine which Employees or Directors outside the United States are eligible to participate in this Plan.

(c)    Modify the terms and conditions of any Award granted to Employees or Directors outside the United States to comply with applicable foreign laws.

(d)    Establish subplans and modify exercise procedures and other terms and procedures, to the extent such actions may be necessary or advisable. Any subplans and modifications to Plan terms and procedures established under this Section 19.9 by the Committee shall be attached to this Plan document as appendices.

(e)    Take any action, before or after an Award is made, that it deems advisable to obtain approval or comply with any necessary local government regulatory exemptions or approvals.

Notwithstanding the above, the Committee may not take any actions hereunder, and no Awards shall be granted that would violate applicable law.

19.10    Uncertificated Shares. To the extent that this Plan provides for issuance of certificates to reflect the transfer of Shares, the transfer of such Shares may be effected on a noncertificated basis, to the extent not prohibited by applicable law or the rules of any stock exchange.

19.11    Unfunded Plan. Participants shall have no right, title, or interest whatsoever in or to any investments that the Company and/or its Subsidiaries and/or its Affiliates may make to aid it in meeting its obligations under this Plan. Nothing contained in this Plan, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind, or a fiduciary relationship between the Company and any Participant, beneficiary, legal representative, or any other individual. To the extent that any individual acquires a right to receive payments from the Company, its Subsidiaries, and/or its Affiliates under this Plan, such right shall be no greater than the right of an unsecured general creditor of the Company, a Subsidiary, or an Affiliate, as the case may be. All payments to be made hereunder shall be paid from the general funds of the Company, a Subsidiary, or an Affiliate, as the case may be, and no special or separate fund shall be established and no segregation of assets shall be made to assure payment of such amounts except as expressly set forth in this Plan.

19.12    No Fractional Shares. No fractional Shares shall be issued or delivered pursuant to this Plan or any Award. The Committee shall determine whether cash, Awards, or other property shall be issued or paid in lieu of fractional Shares or whether such fractional Shares or any rights thereto shall be forfeited or otherwise eliminated.

19.13    Retirement and Welfare Plans. Neither Awards made under this Plan nor Shares or cash paid pursuant to such Awards may be included as “compensation” for purposes of computing the benefits payable to any Participant under the Company’s or any Subsidiary’s or Affiliate’s retirement plans (both qualified and nonqualified) or welfare benefit plans unless such other plan expressly provides that such compensation shall be taken into account in computing a Participant’s benefit.

19.14    Code Section 409A.

(a)    It is intended that the payments and benefits provided under the Plan and any Award shall either be exempt from the application of, or comply with, the requirements of Section 409A of the Code. The Plan and all Award Agreements shall be construed in a manner that effects such intent. Nevertheless, the tax treatment of the benefits provided under the Plan or any Award is not warranted or guaranteed. Neither the Company, its Affiliates nor their respective directors, officers, employees or advisers (other than in his or her capacity as a Participant) shall be held liable for any taxes, interest, penalties or other monetary amounts owed by any Participant or other taxpayer as a result of the Plan or any Award.

(b)    Notwithstanding anything in the Plan or in any Award Agreement to the contrary, to the extent that any amount or benefit that would constitute non-exempt “deferred compensation” for purposes of Section 409A of the Code (“Non-Exempt Deferred Compensation”) would otherwise be payable or distributable, or a different form of payment (e.g., lump sum or installment) of such Non-Exempt Deferred Compensation would be effected, under the Plan or any Award Agreement by reason of the occurrence of a Change of Control, or the Participant’s disability or separation from service, such Non-Exempt Deferred Compensation will not be payable or distributable to the Participant, and/or such different form of payment will not be effected, by reason of such circumstance unless the circumstances giving rise to such Change of Control, disability or separation from service meet any description or definition of “change in control event,” “disability” or “separation from service,” as the case may be, in Section 409A of the Code and applicable regulations (without giving effect to any elective provisions that may be available under such definition). This provision does not affect the dollar amount or prohibit the vesting of any Award upon a Change of Control, disability or separation from service, however defined. If this provision prevents the payment or distribution of any amount or benefit, or the application of a different form of payment of any amount or benefit, such payment or distribution shall be made at the time and in the form that would have applied absent the non-409A-conforming event.

(c)    Notwithstanding anything in the Plan or in any Award Agreement to the contrary, if any amount or benefit that would constitute Non-Exempt Deferred Compensation would otherwise

be payable or distributable under this Plan or any Award Agreement by reason of a participant’s separation from service during a period in which the Participant is a Specified Employee (as defined below), then, subject to any permissible acceleration of payment by the Committee under Treas. Reg. Section 1.409A-3(j)(4)(ii) (domestic relations order), (j)(4)(iii) (conflicts of interest), or (j)(4)(vi) (payment of employment taxes); (i) the amount of such Non-Exempt Deferred Compensation that would otherwise be payable during the six-month period immediately following the Participant’s separation from service will be accumulated through and paid or provided on the first day of the seventh month following the Participant’s separation from service (or, if the Participant dies during such period, within 30 days after the Participant’s death) (in either case, the “Required Delay Period”); and (ii) the normal payment or distribution schedule for any remaining payments or distributions will resume at the end of the Required Delay Period. For purposes of this plan, the term “Specified Employee” has the meaning given such term in Code Section 409A and the final regulations thereunder; provided, however, that, as permitted in such final regulations, the Company’s Specified Employees and its application of the six-month delay rule of Code Section 409A(a)(2)(B)(i) shall be determined in accordance with rules adopted by the Board or any committee of the Board, which shall be applied consistently with respect to all nonqualified deferred compensation arrangements of the Company, including this Plan.

(d)    Whenever an Award conditions a payment or benefit on the Participant’s execution and non-revocation of a release of claims, such release must be executed and all revocation periods shall have expired within sixty (60) days after the date of termination of the Participant’s employment; failing which such payment or benefit shall be forfeited. If such payment or benefit is exempt from Section 409A of the Code, the Company may elect to make or commence payment at any time during such 60-day period. If such payment or benefit constitutes Non-Exempt Deferred Compensation, then, subject to subsection (c) above, (i) if such 60-day period begins and ends in a single calendar year, the Company may make or commence payment at any time during such period at its discretion, and (ii) if such 60-day period begins in one calendar year and ends in the next calendar year, the payment shall be made or commence during the second such calendar year (or any later date specified for such payment under the applicable Award), even if such signing and non-revocation of the release occur during the first such calendar year included within such 60-day period.

(e)    The Company shall have the sole authority to make any accelerated distribution permissible under Treas. Reg. Section 1.409A-3(j)(4) to Participants of deferred amounts, provided that such distribution(s) meets the requirements of Treas. Reg. Section 1.409A-3(j)(4).

19.15    Nonexclusivity of This Plan. The adoption of this Plan shall not be construed as creating any limitations on the power of the Board or Committee to adopt such other compensation arrangements as it may deem desirable for any Participant.

19.16    No Constraint on Corporate Action. Nothing in this Plan shall be construed to: (a) limit, impair, or otherwise affect the Company’s or a Subsidiary’s or an Affiliate’s right or power to make adjustments, reclassifications, reorganizations, or changes of its capital or business structure, or to merge or consolidate, or dissolve, liquidate, sell, or transfer all or any part of its business or assets; or, (b) limit the right or power of the Company or a Subsidiary or an Affiliate to take any action which such entity deems to be necessary or appropriate.

19.17    Governing Law. The Plan and each Award Agreement shall be governed by the laws of the State of Georgia, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Plan to the substantive law of another jurisdiction. Unless otherwise provided in the Award Agreement, recipients of an Award under this Plan are deemed to submit to the exclusive jurisdiction and venue of the federal or state courts of Georgia to resolve any and all issues that may arise out of or relate to this Plan or any related Award Agreement.

19.18    Indemnification. Subject to requirements of Georgia law, each individual who is or shall have been a member of the Board, or a committee appointed by the Board, or an officer of the Company to whom authority was delegated in accordance with Article 3, shall be indemnified and held harmless by the Company against and from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by the Participant in connection with or resulting from any claim, action, suit, or proceeding to which the Participant may be a party or in which the Participant may be involved by reason of any action taken or failure to act under this Plan and against and from any and all amounts paid by the Participant in settlement thereof, with the Company’s approval, or paid by the Participant in satisfaction of any judgment in any such action, suit, or proceeding against the Participant, provided the Participant shall give the Company an opportunity, at its own expense, to handle and defend the same before the Participant undertakes to handle and defend it on the Participant’s own behalf, unless such loss, cost, liability, or expense is a result of the Participant’s own willful misconduct or except as expressly provided by statute.

The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such individuals may be entitled under the Company’s Articles of Incorporation or Bylaws, as a matter of law, or otherwise, or any power that the Company may have to indemnify them or hold them harmless.

19.19    Right of Offset. The Company and its Affiliates shall have the right to offset against the obligations to make payment or issue any Shares to any Participant under the Plan any outstanding amounts (including travel and entertainment advance balances, loans, tax withholding amounts paid by the employer or amounts repayable to the Company or Affiliate pursuant to tax equalization, housing, automobile, or other employee programs) such Participant then owes to the company or Affiliate and any amounts the Committee otherwise deems appropriate pursuant to any Company or Affiliate policy or agreement.

This indemnification is limited to the extent such costs and expenses are not covered under insurance as may be now or hereafter provided by Synovus.

ARTICLE 5

AGENT OF THE PLAN

The Agent shall receive all contributions made by Synovus and Participants in cash only. All contributions so received (hereinafter referred to as the “Fund”), shall be held, managed, and administered pursuant to the terms of the Plan. No part of the Fund shall be used for or diverted to purposes other than for the exclusive benefit of the Participants and former Participants in the Plan.

Any Agent may be removed by Synovus at any time with or without cause. Any Agent may resign at any time upon 120 days notice in writing to Synovus. Upon removal or resignation of such Agent, Synovus shall appoint a successor Agent who shall have the same powers and duties as those conferred upon the original Agent hereunder. Upon acceptance of such appointment by the successor Agent, the

predecessor Agent shall assign, transfer, and pay over to such successor Agent the funds and properties then constituting the Fund and any and all records it might have with regard to the Fund and the administration of the Fund.

The Agent shall have the following powers and authority in the administration and investment of the Fund:

(a)    To purchase for the benefit of the Participants in the Plan shares of Synovus Common Stock in its name as Agent, and to retain the same and to cause the shares of Synovus Common Stock held as part of the Fund to be allocated, reallocated and disposed of pursuant to the terms of the Plan.

(b)    To cause any Synovus Common Stock held as part of the Fund to be registered in the Agent’s own name or in the name of one or more nominees, but the books and records of the Agent shall at all times show that all such investments are part of the Fund.

(c)    To keep such portions of the Fund in cash or cash balances as the Agent, from time to time, may in its sole discretion deem to be in the best interests of the Participants in the Plan without liability for interest thereon.

(d)    To make, execute, acknowledge and deliver any and all documents of transfer and conveyance and any and all other instruments as may be necessary or appropriate to carry out the powers herein granted.

(e)    To employ subagents to engage in the actual open market purchase of Synovus Common Stock for the benefit of the Participants in the Plan.

(f)    To do all such acts, take all such proceedings, and exercise all such rights and privileges, although not specifically mentioned herein, as the Agent may deem necessary or desirable to administer the Fund, and to carry out and satisfy the purposes and intent of the Plan.

The Agent shall keep accurate and detailed accounts of all receipts, disbursements, and other transactions hereunder, including, but not limited to, Participant and Matching Contributions received, dividends and other distributions received, and Synovus Common Stock purchased and sold, allocated and held for, and Synovus Common Stock distributed to, Participants hereunder. All accounts, books, and records relating to such transactions shall be open to inspection and audit at all reasonable times by any person designated by Synovus.

On or before the fifteenth day following the close of each month or upon such other reporting schedules and for such other reporting periods as Synovus and the Agent shall agree, the Agent shall file with Synovus a written report setting forth all receipts, disbursements, and other transactions effected during such preceding month or reporting period, and setting forth the current status of the Fund.

ARTICLE 6

STOCK PURCHASES

The Agent shall purchase shares of Synovus Common Stock in the open market for the benefit of the Participants in the Plan on a quarterly basis.

In the event that the Agent retains the services of subagents to make such purchases of shares of Synovus Common Stock, such subagents shall not be controlled by, controlling or under common control with Synovus or its affiliates. Neither Synovus nor any of its affiliates shall have, nor exercise, directly or indirectly, any control or influence over the times when, or the prices at which, Synovus Common Stock may be purchased by the Agent or its subagents, the amounts of Synovus Common Stock to be so purchased or the manner in which such Synovus Common Stock is to be purchased. The Agent may retain the services of said subagents only upon the execution of subagency agreements by and between the Agent and subagents which sets forth terms and conditions not materially different from those contained herein with regard to the purchase and sale of Synovus Common Stock.

Neither the Agent, Synovus, nor any subagent retained by the Agent, shall have any responsibility as to the value of Synovus Common Stock acquired under the Plan. The duties of the Agent and any subagent to cause the purchase of Synovus Common Stock under the Plan shall be subject to any and all legal restrictions or limitations imposed at the time by governmental authority, including, but not limited to, the Securities and Exchange Commission, and shall be subject to any other restrictions, limitations or considerations deemed valid by such Agent or any subagent. Accordingly, neither the Agent, Synovus, nor any subagent shall be liable in any way if, as a result of such restrictions, limitations or considerations, the whole amount of funds available under the Plan for the purchase of Synovus Common Stock is not applied to the purchase of such shares at the time herein otherwise provided or contemplated.

ARTICLE 7

ALLOCATION OF STOCK

As promptly as practical after each purchase by the Agent (or any subagent) of Synovus Common Stock for the benefit of the Participants in the Plan, the Agent shall determine the average cost per share of all shares so purchased. The Agent shall then proportionally allocate such shares to the Plan Accounts of the Participants, charging each such Participant with the average cost, including transactional costs, of the shares so allocated. Full shares and fractional share interests in one share (to three decimal places) shall be allocated.

ARTICLE 8

ISSUANCE OF SHARES OUT OF THE PLAN

    A Participant may request that the Agent issue shares out of the Plan for all or a part of the full number of shares of Synovus Common Stock in a Participant’s Plan

Account for which the six month holding period pursuant to Article 16 has been satisfied or for which the six month holding period does not apply. As promptly as practicable after the later of such Participant’s request and satisfaction of the six-month holding period, if applicable, the Agent will issue such shares out of the Plan and transfer the shares electronically to the Participant’s Synovus Dividend Reinvestment and Direct Stock Purchase Plan account or to a another account specified by the Participant or, if the Participant requests a stock certificate, the Agent will issue the full number of shares out of the Plan and a check representing the value of the fractional share interest and send by U.S. mail a Synovus Common Stock certificate and the check for fractional share interest to the Participant at the Participant’s address of record.

    A Participant may request that the Agent issue shares out of the Plan in the name of another person and the Agent will issue the shares to such other person in accordance with Participant’s instructions; provided, however, that if such instructions are not sufficiently specific for the Agent to be able to comply with such instructions, the Agent shall return such request to the Participant without issuing shares out of such Participant’s account in the Plan.

    Notwithstanding anything herein to the contrary, the Agent will carry out a Participant’s instructions to issue shares out of the Plan only if the Participant clearly indicates the number of shares to be issued out of the Plan or specifies that all shares held in such Participant’s Plan Account are to be issued out of the Plan; otherwise, the Agent shall return such request to the Participant without issuing shares out of such Participant’s account in the Plan.

ARTICLE 9

SALE OF SHARES

    A Participant may request that the Agent sell all or a part of the full number of shares of Synovus Common Stock in a Participant’s Stock Share Account. To facilitate a sale, the Participant must forward a sell request to Synovus Shareholder Services via e-mail, phone or U.S. mail. Synovus Shareholder Services shall forward such request to the Agent. As promptly as practicable after the later of such Participant’s request and satisfaction of the six-month holding period, if applicable, the Agent will sell all or the specified number of shares, deduct brokerage commissions and a transaction charge, and mail a check for the net proceeds to the Participant at the Participant’s address of record. The Participant request must clearly indicate the number of shares to be sold, or specify that all shares held in such Participant’s Plan Account are to be sold; otherwise, Synovus Shareholder Services shall return such request to the Participant without selling any shares in such Participant’s account. No Participant shall have the authority or power to direct the date or sales price at which shares may be sold.

ARTICLE 10

DIVIDENDS AND DISTRIBUTIONS

Stock dividends and stock splits received by the Agent will be allocated by such Agent to each Participant’s Plan Account to the extent that such stock is attributable to the allocated Synovus Common Stock in such Participant’s Plan Account. All cash dividends received by the Agent shall be used to acquire additional shares of Synovus Common Stock pursuant to the provisions of the Plan, and such shares so acquired will be allocated proportionately to the Plan Accounts of Participants. Shares acquired through such dividend reinvestment shall not be subject to the six-month holding period of Article 16.

ARTICLE 11

VOTING RIGHTS

Each Participant in the Plan shall have the rights and powers of ordinary shareholders with respect to the shares of Synovus Common Stock in such Participant’s Plan Account, including, but not limited to, the right to vote such shares. Synovus shall deliver or cause to be delivered to Participants at the time and in the manner such materials are sent to Synovus shareholders generally all reports, proxy solicitation materials and all other disclosure type communications distributed to Synovus shareholders generally.

ARTICLE 12

REPORTS TO PARTICIPANTS

As soon as practical following the end of each Plan Year, or more often and as often as Synovus may elect, Synovus and/or the Agent shall send to each Participant a written report of all transactions for such Participant’s benefit under the Plan for such Plan year.

ARTICLE 13

TERMINATION OF PARTICIPATION IN THE PLAN

A Participant may terminate his or her participation in the Plan by contacting Synovus at least thirty (30) days prior to a Contribution Date. The Participant’s request to terminate participation in the Plan will be communicated to the Agent by Synovus in accordance with Synovus’ administrative procedures for the Plan. Such termination will be effective as promptly as practicable.

As promptly as practicable after receipt of a Participant’s termination notice, the Agent will purchase shares of Synovus Common Stock with the cash remaining in the Participant’s Plan Account as of the next quarterly purchase date. As promptly as practicable thereafter, in accordance with and after receipt by the Agent of such Participant’s request, the Agent will issue such shares out of the Plan (provided that, other than in the case of a termination by reason of death, the shares have been held at

least six months pursuant to Article 16, if applicable) and transfer the shares electronically to the Participant’s account established under the Synovus Financial Corp. Dividend Reinvestment and Direct Stock Purchase Plan account or to an electronic common stock account established for the Participant; or, if the Participant requests a stock certificate, the Agent will issue the full number of shares out of the Plan and a check representing the value of the fractional share interest and send by U.S. mail a Synovus Common Stock certificate and the check for fractional share interest to the Participant at the Participant’s address of record. The Participant may also request to have some or all of the shares of Synovus Common Stock in such Participant’s Plan Account sold in which case the Agent will sell the number of shares specified by the Participant and issue a check made payable to the Participant for the net cash proceeds from the sale of such shares, after deduction of brokerage commissions and a transaction charge.

If no delivery instructions are provided by the former Participant, the shares will be transferred to the Participant’s Synovus Dividend Reinvestment and Direct Stock Purchase Plan Account, or, if the Participant does not have a Synovus Dividend Reinvestment and Direct Stock Purchase Plan Account, then the Agent will transfer the shares to an electronic common stock account for the Participant.

    A Participant may request that the Agent issue shares out of the Plan in the name of another person and the Agent will issue the shares to such other person in accordance with Participant’s instructions; provided, however, that if such instructions are not sufficiently specific for the Agent to be able to comply with such instructions, the Agent shall return such request to the Participant without issuing shares out of such Participant’s account in the Plan.

    Notwithstanding anything herein to the contrary, the Agent will carry out a Participant’s instructions to issue shares out of the Plan only if the Participant clearly indicates the number of shares to be issued out of the Plan or specifies that all shares held in such Participant’s Plan Account are to be issued out of the Plan; otherwise, the Agent shall return such request to the Participant without issuing shares out of such Participant’s account in the Plan.

ARTICLE IV

PARTICIPATING EMPLOYER MATCHING CONTRIBUTIONS

Participating Employers shall make matching contributions to the Plan for each of their employees who are Participants in the Plan of up to fifty percent (50%) of the amount of each such Participant's payroll deduction to the Plan. The Board of Directors may elect to establish a lower matching contribution or may eliminate the matching contribution altogether. Participants shall be provided with written notice of any decrease in the matching contribution percentage prior to the effective date of such decrease.

Participating Employer contributions shall be made on Deduction Dates. As promptly as practicable on or after each Deduction Date, Participating Employers will remit their contributions to the Administrator, who will forward such contributions to the Agent on a quarterly basis.

As Participating Employer contributions to the Plan must be treated by the Participants for whom such contributions are made as compensation income, such amounts will be reflected on the payroll voucher of such Participants as additional compensation income paid by the Participating Employers to such Participants, and such amounts will in turn appear on the payroll vouchers of such Participants as having been withheld from their pay by the Participating Employers to reflect the Participating Employers' contributions made to the Plan for the benefit of such Participants, and the Participating Employers shall withhold additional State and Federal income taxes and Social Security taxes from the pay of such Participants to cover such amount, all at the times Participant payroll deductions are withheld.

Synovus shall indemnify each employee of Synovus and the Participating Employers involved in the administration of the Plan against all costs, expenses and liabilities, including attorney's fees, incurred in connection with any action, suit, or proceeding instituted against such employee alleging any act or omission or

commission performed by such employee while acting in good faith in discharging his or her duties with respect to the Plan.

(c)    Effect of Retirement. If Director’s service with the Board of Directors terminates due to Director’s retirement pursuant to the provisions of the Corporation’s Corporate Governance Guidelines (as they may be amended from time to time), then any RSUs which are not vested at

the time of such termination of service will become vested automatically as of the date of such termination of service. In addition, all previous Restricted Stock Unit Agreements entered into between the Director and the Corporation that vest automatically upon the attainment of age 72 are hereby amended to instead vest automatically upon the Director’s retirement pursuant to the provisions of the Corporation’s Corporate Governance Guidelines (as they may be amended from time to time).

(d)    No Forfeiture of Vested RSUs. Any RSUs which vest pursuant to the preceding provisions of this Section 2 will not thereafter be forfeited.

3.    Conversion of RSUs and Issuance of Shares

Upon vesting of the RSUs as set forth in Section 2, one share of the Corporation’s Common Stock shall be issued for each RSU that vests on such vesting date, subject to the terms and conditions of this Agreement and the Plan.

4.    Status of Director

The Director shall not be, or have rights as, a stockholder of the Corporation with respect to any of the shares of Common Stock subject to the RSUs unless the shares underlying the RSUs have been issued and delivered to him or her. The Corporation shall not be required to issue or transfer any certificates for shares of Common Stock for the RSUs until all applicable requirements of law have been complied with and such shares have been duly listed on any securities exchange on which the Common Stock may then be listed.

5.    Dividend Equivalents

The RSUs will be credited with dividend equivalents equal to amount of cash dividend payments that would have otherwise been paid if the shares of the Corporation’s Common Stock represented by the RSUs (including deemed reinvested additional shares attributable to the RSUs pursuant to this paragraph) were actually outstanding. These dividend equivalents will be deemed to be reinvested in additional shares of the Corporation’s Common Stock determined by dividing the deemed cash dividend amount by the Fair Market Value (as defined in the Plan) of a share of the Corporation’s Common Stock on the applicable dividend payment date. Such credited amounts will be added to the RSUs and will become transferable in accordance with Section 2 based on the transferability of the initial RSUs to which they are attributable. In addition, the RSUs will be credited with any dividends or distributions that are paid in shares of the Corporation’s Common Stock represented by the RSUs and will otherwise be adjusted by the Committee for other capital or corporate events as provided for in the Plan.

6.    General Provisions

(a)    Administration, Interpretation and Construction. The terms and conditions set forth in this Agreement will be administered, interpreted and construed by the Compensation Committee, whose decisions will be final, conclusive and binding on the Corporation, on Director and on anyone claiming under or through the Corporation or Director. Without limiting the generality of the foregoing, any determination as to whether an event has occurred or failed to occur which causes the RSUs to be transferable pursuant to the terms and conditions set forth in this Agreement, will be made in the good faith but absolute discretion of the Compensation

2

Committee. By accepting the transfer of RSUs, Director irrevocably consents and agrees to the terms and conditions set forth in this Agreement and to all actions, decisions and determinations to be taken or made by the Compensation Committee in good faith pursuant to the terms and conditions set forth in this Agreement.

(b)    Withholding. The Corporation will have the right to withhold from any payments to be made to Director (whether under this Agreement or otherwise) any taxes the Corporation determines it is required to withhold with respect to Director under the laws and regulations of any governmental authority, whether Federal, state or local and whether domestic or foreign, in connection with this Agreement, including, without limitation, taxes in connection with the transfer of RSUs. Failure to submit any such withholding taxes shall be deemed to cause otherwise transferable RSUs not to become transferable.

(c)    Rights Not Assignable or Transferable. No rights under this Agreement will be assignable or transferable other than by will or the laws of descent and distribution, either voluntarily, or, to the full extent permitted by law, involuntarily, by way of encumbrance, pledge, attachment, levy or charge of any nature except as otherwise provided in this Agreement. Director’s rights under this Agreement will be exercisable during Director’s lifetime only by Director or by Director’s guardian or legal representative.

(d)    Terms and Conditions Binding. The terms and conditions set forth in the Plan and in this Agreement will be binding upon and inure to the benefit of the Corporation, its successors and assigns, including any assignee of the Corporation and any successor to the Corporation by merger, consolidation or otherwise, and Director, Director’s heirs, devisees and legal representatives.

(e)    No Liability for Good Faith Business Acts or Omissions. Director recognizes and agrees that the Compensation Committee, the Board, or the officers, agents or employees of the Corporation and its Subsidiaries, in their oversight or conduct of the business and affairs of the Corporation and its Subsidiaries, may in good faith cause the Corporation or a Subsidiary to act, or to omit to act, in a manner that may, directly or indirectly, prevent the RSUs from becoming transferable. No provision of this Agreement will be interpreted or construed to impose any liability upon the Corporation, a Subsidiary, the Compensation Committee, Board or any officer, agent or employee of the Corporation or a Subsidiary, for the inability to transfer RSUs that may result, directly or indirectly, from any such action or omission.

(f)    Recapitalization. In the event that Director receives, with respect to RSUs, any securities or other property (other than cash dividends) as a result of any stock dividend or split, spin-off, recapitalization, merger, consolidation, combination or exchange of shares or a similar corporate change, any such securities or other property received by Director will likewise be held by the Plan’s agent and be subject to the terms and conditions set forth in this Agreement and will be included in the term “RSUs.”

(g)    Appointment of Agent. By accepting the transfer of RSUs, Director irrevocably nominates, constitutes, and appoints the Plan’s agent as Executive’s agent for purposes of surrendering or transferring the RSUs to the Corporation upon any forfeiture required or authorized by this Agreement. This power is intended as a power coupled with an interest and will survive Director’s death. In addition, it is intended as a durable power and will survive Director’s disability.

3

(h)    Legal Representative. In the event of Director’s death or a judicial determination of Director’s incompetence, reference in this Agreement to Director shall be deemed, where appropriate, to Director’s heirs or devises.

(i)    Titles. The titles to sections or paragraphs of this Agreement are intended solely for convenience and no provision of this Agreement is to be construed by reference to the title of any section or paragraph.

(j)    Plan Governs. The RSUs are being transferred to Director pursuant to and subject to the Plan, a copy of which is available upon request to the Corporate Secretary of the Corporation. The provisions of the Plan are incorporated herein by this reference, and all capitalized terms in this Agreement shall have the same meanings given to such terms in the Plan. The terms and conditions set forth in this Agreement will be administered, interpreted and construed in accordance with the Plan, and any such term or condition which cannot be so administered, interpreted or construed will to that extent be disregarded.

(k)    Complete Agreement. This instrument contains the entire agreement of the parties relating to the subject matter of this Agreement and supersedes and replaces all prior agreements and understandings with respect to such subject matter. The parties hereto have made no agreements, representations or warranties relating to the subject matter of this Agreement which are not set forth herein or incorporated by reference.

(l)    Amendment; Modification; Wavier. No provision set forth in this Agreement may be amended, modified or waived unless such amendment, modification or waiver shall be authorized by the Compensation Committee and shall be agreed to in writing, signed by Director and by an officer of the Corporation duly authorized to do so. No waiver by either party hereto of any breach by the other party of any condition or provision set forth in this Agreement to be performed by such other party will be deemed a waiver of a subsequent breach of such condition or provision, or will be deemed a waiver of a similar or dissimilar provision or condition at the same time or at any prior or subsequent time.

(m)    Governing Law. The validity, interpretation, performance and enforcement of the terms and conditions set forth in this Agreement will be governed by the laws of the State of Georgia, the state in which the Corporation is incorporated, without giving effect to the principles of conflicts of law of that state.

    The Corporation has issued the RSUs in accordance with the foregoing terms and conditions and in accordance with the provisions of the Plan. By signing below, Director hereby agrees to the foregoing terms and conditions of the RSUs.

    IN WITNESS WHEREOF, Director has set Director’s hand and seal, effective as of the date and year set forth above.

General

The accompanying unaudited interim consolidated financial statements of Synovus Financial Corp. include the accounts of the Parent Company and its consolidated subsidiaries. Synovus Financial Corp. is a financial services company based in Columbus, Georgia. Through its wholly-owned subsidiary, Synovus Bank, a Georgia state-chartered bank that is a member of the Federal Reserve System, the Company provides commercial and retail banking in addition to a full suite of specialized products and services including private banking, treasury management, wealth management, mortgage services, premium finance, asset-based lending, structured lending, and international banking.

The accompanying unaudited interim consolidated financial statements have been prepared in accordance with the instructions to the SEC Form 10-Q and Article 10 of Regulation S-X; therefore, they do not include all information and footnotes necessary for a fair presentation of financial position, results of operations, comprehensive income, and cash flows in conformity with GAAP. All adjustments consisting of normally recurring accruals that, in the opinion of management, are necessary for a fair presentation of the consolidated financial position and results of operations for the periods covered by this Report have been included. The accompanying unaudited interim consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes appearing in Synovus' 2020 Form 10-K.

Reclassifications

Prior periods' consolidated financial statements are reclassified whenever necessary to conform to the current periods' presentation.

Use of Estimates in the Preparation of Financial Statements

In preparing the consolidated financial statements in accordance with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the respective consolidated balance sheets and the reported amounts of revenues and expenses for the periods presented. Actual results could differ significantly from those estimates.

Material estimates that are particularly susceptible to change relate to the determination of the ACL; estimates of fair value; income taxes; and contingent liabilities.

As of March 31, 2021, Synovus had 115 investment securities in a loss position for less than twelve months and no investment securities in a loss position for twelve months or longer. Synovus does not intend to sell investment securities in an unrealized loss position prior to the recovery of the unrealized loss, which may not be until maturity, and has the ability and intent to hold those securities for that period of time. Additionally, Synovus is not currently aware of any circumstances which will require it to sell any of the securities that are in an unrealized loss position prior to the respective securities' recovery of all such unrealized losses. As such, no write-downs to the amortized cost basis of the portfolio were recorded at March 31, 2021.

At March 31, 2021, no ACL was established for investment securities. Substantially all of the unrealized losses on the securities portfolio were the result of changes in market interest rates compared to the date the securities were acquired rather than the credit quality of the issuers or underlying loans. U.S. Treasury and agency securities and agency mortgage-backed securities are issued, guaranteed or otherwise supported by the United States government, an agency of the United States government, or a government sponsored enterprise.

The amortized cost and fair value by contractual maturity of investment securities available for sale at March 31, 2021 are shown below. The expected life of MBSs or CMOs may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. For purposes of the maturity table, MBSs and CMOs, which are not due at a single maturity date, have been classified based on the final contractual maturity date.

Of the interest income recognized during the three months ended March 31, 2021 and 2020, cash-basis interest income was $622 thousand and $961 thousand, respectively.

Pledged Loans

Loans with carrying values of $14.27 billion and $15.05 billion, respectively, were pledged as collateral for borrowings and capacity at March 31, 2021 and December 31, 2020, respectively, to the FHLB and Federal Reserve Bank.

Portfolio Segment Risk Factors

The risk characteristics and collateral information of each portfolio segment are as follows:

Commercial and Industrial Loans - The C&I loan portfolio is comprised of general middle market and commercial banking clients across a diverse set of industries. In accordance with Synovus' lending policy, each loan undergoes a detailed underwriting process which incorporates uniform underwriting standards and oversight in proportion to the size and complexity of the lending relationship. These loans are secured by collateral such as business equipment, inventory, and real estate. Whether for real estate or non-real estate purpose, credit decisions on loans in the C&I portfolio are based on cash flow from the operations of the business as the primary source of repayment of the debt, with underlying real estate or other collateral being the secondary source of repayment. PPP loans, which are categorized as C&I loans, were $2.36 billion at March 31, 2021 and are guaranteed by the SBA.

Commercial Real Estate Loans - CRE loans primarily consist of income-producing investment properties loans. Additionally, CRE loans include 1-4 family properties loans as well as land and development loans. Investment properties loans consist of construction and mortgage loans for income-producing properties and are primarily made to finance multi-family properties, hotels, office buildings, shopping centers, warehouses and other commercial development properties. 1-4 family properties loans include construction loans to homebuilders and commercial mortgage loans related to 1-4 family rental properties and are almost always secured by the underlying property being financed by such loans. These properties are primarily located in the markets served by Synovus. Land and development loans include commercial and residential development as well as land acquisition loans and are secured by land held for future development, typically in excess of one year. Properties securing these loans are substantially within markets served by Synovus, and loan terms generally include personal guarantees from the principals. Loans in this portfolio are underwritten based on the LTV of the collateral and the capacity of the guarantor(s).

Consumer Loans - The consumer loan portfolio consists of a wide variety of loan products offered through Synovus' banking network including first and second residential mortgages, HELOCs, and credit card loans, as well as home improvement loans, student, personal, and auto loans from third-party lending. The majority of Synovus' consumer loans are consumer mortgages and HELOCs secured by first and second liens on residential real estate primarily located in the markets served by Synovus. The primary source of repayment for all consumer loans is generally the personal income of the borrower(s).

Credit Quality Indicators

The credit quality of the loan portfolio is reviewed and updated no less frequently than quarterly using the standard asset classification system utilized by the federal banking agencies. These classifications are divided into three groups: Not Criticized (Pass), Special Mention, and Classified or Adverse rating (Substandard, Doubtful, and Loss) and are defined as follows:

Pass - loans which are well protected by the current net worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less cost to acquire and sell in a timely manner, of any underlying collateral.

Special Mention - loans which have potential weaknesses that deserve management's close attention. These loans are not adversely classified and do not expose an institution to sufficient risk to warrant an adverse classification.

Substandard - loans which are inadequately protected by the current net worth and paying capacity of the obligor or by the collateral pledged, if any. Loans with this classification are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

Doubtful - loans which have all the weaknesses inherent in loans classified as Substandard with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable on the basis of currently known facts, conditions, and values.

Loss - loans which are considered by management to be uncollectible and of such little value that their continuance on the institution's books as an asset, without establishment of a specific valuation allowance or charge-off, is not warranted. Synovus fully reserves for any loans rated as Loss.

In the following tables, consumer loans are generally assigned a risk grade similar to the classifications described above; however, upon reaching 90 days and 120 days past due, they are generally downgraded to Substandard and Loss, respectively, in accordance with the FFIEC Retail Credit Classification Policy. Additionally, in accordance with Interagency Supervisory Guidance, the risk grade classifications of consumer loans (consumer mortgages and HELOCs) secured by junior liens on 1-4

family residential properties also consider available information on the payment status of any associated senior liens with other financial institutions.

The following tables summarize each loan portfolio class by risk grade and origination year as of March 31, 2021 and December 31, 2020 as required under CECL.

(4)    Represent amounts that were 120 days past due. These credits are downgraded to the Loss category with an ALL equal to the full loan amount and are generally charged off upon reaching 181 days past due in accordance with the FFIEC Retail Credit Classification Policy.

Collateral-Dependent Loans

We classify a loan as collateral-dependent when our borrower is experiencing financial difficulty, and we expect repayment to be provided substantially through the operation or sale of collateral. Our commercial loans have collateral that is comprised of real estate and business assets. Our consumer loans have collateral that is substantially comprised of residential real estate.

There were no significant changes in the extent to which collateral secures our collateral-dependent loans during the three months ended March 31, 2021.

Rollforward of Allowance for Loan Losses

The following tables detail the changes in the ALL by loan segment for the three months ended March 31, 2021 and 2020.

	As Of and For the Three Months Ended March 31, 2021
(in thousands)	Commercial & Industrial		Commercial Real Estate		Consumer		Total
Allowance for loan losses:

Ending balance	$	254,777	$	113,812	$	194,625	$	563,214
	As Of and For the Three Months Ended March 31, 2020
(in thousands)	Commercial & Industrial		Commercial Real Estate		Consumer		Total
Allowance for loan losses:
Beginning balance, prior to adoption of ASC 326	$	145,782	$	67,430	$	68,190	$	281,402
Impact from adoption of ASC 326	(2,310)		(651)		85,955		82,994
Beginning balance, after adoption of ASC 326	$	143,472	$	66,779	$	154,145	$	364,396
Charge-offs	(14,885)		(1,017)		(7,972)		(23,874)
Recoveries	1,741		399		1,673		3,813
Provision for loan losses	86,622		40,956		21,539		149,117
Ending balance	$	216,950	$	107,117	$	169,385	$	493,452

The ALL of $563.2 million and the reserve for unfunded commitments of $51.5 million, which is recorded in other liabilities, comprise the total ACL of $614.7 million at March 31, 2021, which decreased during the first quarter of 2021 by $38.8 million, resulting in an ACL to loans coverage ratio of 1.58%. The modeling assumptions for the first quarter of 2021 utilized a two-year reasonable and supportable forecast period and comprised a multiple-scenario economic framework. To the extent the lives of the loans in the portfolio extend beyond the period for which a reasonable and supportable forecast can be made, the Company reverts, on a straight-line basis back to the historical rates over a one-year period. The ACL at March 31, 2021 incorporates a baseline outlook with moderate economic expansion and benefits from the estimated impact of government stimulus. Provision for credit losses includes the provisions for loan losses and unfunded commitments. The reversal of provision for credit losses of $18.6 million for the three months ended March 31, 2021 included net charge-offs of $20.2 million and resulted from the improved economic outlook and stable loan portfolio metrics that were partially offset by the increased size of the loan portfolio including $15.2 million in reserves added as result of purchases of $607.0 million of third-party lending loans, including a $476.2 million prime auto purchase.

TDRs

Information about Synovus' TDRs is presented in the following tables. Synovus began entering into loan modifications with borrowers in response to the COVID-19 pandemic, some of which have not been classified as TDRs, and therefore are not included in the discussion below.

Goodwill is not amortized but is evaluated for impairment on an annual basis or whenever an event occurs or circumstances change to indicate that it is more likely than not that an impairment loss has been incurred (i.e., a triggering event). Synovus performs its annual evaluation of goodwill impairment during the fourth quarter of each year. See "Part II - Item 8. Financial Statements and Supplementary Data - Note 7 - Goodwill and Other Intangible Assets" to the consolidated financial statements of Synovus' 2020 Form 10-K for information on Synovus' quantitative assessments of goodwill impairment during 2020.

The following table shows the gross carrying amount and accumulated amortization of other intangible assets as of March 31, 2021 and December 31, 2020, which primarily consist of core deposit intangible assets. The CDI is being amortized over its estimated useful life of approximately ten years utilizing an accelerated method. Aggregate other intangible assets amortization expense for the three months ended March 31, 2021 and 2020 was $2.4 million and $2.6 million, respectively.

Fair Value Option

Synovus has elected the fair value option for mortgage loans held for sale primarily to ease the operational burden required to maintain hedge accounting for these loans. Synovus is still able to achieve effective economic hedges on mortgage loans held for sale without the time and expense needed to manage a hedge accounting program.

The following table summarizes the difference between the fair value and the UPB of mortgage loans held for sale and the changes in fair value of these loans. An immaterial portion of these changes in fair value was attributable to changes in instrument-specific credit risk.

Summary of Derivative Instruments [Abstract]

Derivative Instruments and Hedging Activities

Note 7 - Derivative Instruments and Hedging Activities

Synovus utilizes derivative instruments to manage its exposure to various types of interest rate risk, exposures related to liquidity and credit risk, and to facilitate customer transactions. The primary types of derivative instruments utilized by Synovus consist of interest rate swaps, interest rate lock commitments made to prospective mortgage loan customers, commitments to sell fixed-rate mortgage loans, and foreign currency exchange forwards. Interest rate lock commitments represent derivative instruments since it is intended that such loans will be sold. Synovus is party to master netting arrangements with its dealer counterparties; however, Synovus does not offset assets and liabilities under these arrangements for financial statement presentation purposes. See "Part II - Item 8. Financial Statements and Supplementary Data - Note 1 - Summary of Significant Accounting Policies" to the consolidated financial statements of Synovus' 2020 Form 10-K for additional information regarding accounting policies for derivatives.

Hedging Derivatives

Cash flow hedge relationships mitigate exposure to the variability of future cash flows or other forecasted transactions. Synovus has entered into interest rate swap contracts to manage overall cash flow changes related to interest rate risk exposure on index-based variable rate commercial loans. The contracts effectively modify Synovus' exposure to interest rate risk by utilizing receive fixed/pay index-based variable rate interest rate swaps.

For cash flow hedges, if the hedged exposure is a cash flow exposure, the effective portion of the gain or loss on the derivative instrument is reported initially as a component of accumulated other comprehensive income (loss), net of the tax impact, and subsequently reclassified into earnings when the hedged transaction affects earnings with the impacts recorded in the same income statement line item used to present the earnings effect of the hedged item. When a cash flow hedge relationship is discontinued but the hedged cash flows, or forecasted transactions, are still expected to occur, gains or losses that were accumulated in OCI are amortized into earnings over the same periods which the hedged transactions would have affected earnings. If, however, it is probable the forecasted transactions will no longer occur, the remaining accumulated amounts in OCI at the de-designation date are immediately recognized in earnings.

Synovus recorded unrealized gains of $757 thousand, or $565 thousand, after tax, in OCI during the first quarter of 2021 and $9.8 million, or $7.3 million, after-tax, in OCI, during the first quarter of 2020, related to terminated cash flow hedges, which are being recognized into earnings in conjunction with the effective terms of the original swaps through the fourth

quarter of 2025. Synovus recognized pre-tax income of $1.6 million during the three months ended March 31, 2021 related to the amortization of terminated cash flow hedges.

As of March 31, 2021, Synovus expects to reclassify into earnings approximately $43 million in pre-tax income due to the receipt or payment of interest payments on all cash flow hedges within the next twelve months. Included in this amount is approximately $13 million in pre-tax income related to the amortization of terminated cash flow hedges. As of March 31, 2021, the maximum length of time over which Synovus is hedging its exposure to the variability in future cash flows is through the first quarter of 2026.

For derivative instruments that are not designated as hedging instruments, changes in the fair value of the derivatives are recognized in earnings immediately.

Counterparty Credit Risk and Collateral

Entering into derivative contracts potentially exposes Synovus to the risk of counterparties’ failure to fulfill their legal obligations, including, but not limited to, potential amounts due or payable under each derivative contract. Notional principal amounts are often used to express the volume of these transactions, but the amounts potentially subject to credit risk are much smaller. Synovus assesses the credit risk of its dealer counterparties by regularly monitoring publicly available credit rating information, evaluating other market indicators, and periodically reviewing detailed financials. Dealer collateral requirements are determined via risk-based policies and procedures and in accordance with existing agreements. Synovus seeks to minimize dealer credit risk by dealing with highly rated counterparties and by obtaining collateral for exposures above certain predetermined limits. Management closely monitors credit conditions within the customer swap portfolio, which management deems to be of higher risk than dealer counterparties. Collateral is secured at origination and credit related fair value adjustments are recorded against the asset value of the derivative as deemed necessary based upon an analysis, which includes consideration of the current asset value of the swap, customer risk rating, collateral value, and customer standing with regards to its swap contractual obligations and other related matters. Such asset values fluctuate based upon changes in interest rates regardless of changes in notional amounts and changes in customer specific risk.

Collateral Requirements

Pursuant to the Dodd-Frank Act, certain derivative transactions have collateral requirements, both at the inception of the trade and as the value of each derivative position changes. As of March 31, 2021 and December 31, 2020, collateral totaling $121.7 million and $155.4 million, respectively, was pledged to the derivative counterparties to comply with collateral requirements. For derivatives cleared through central clearing houses, the variation margin payments made are legally characterized as settlements of the derivatives. As a result, these variation margin payments are netted against the fair value of the respective derivative contracts in the consolidated balance sheets and related disclosures. At March 31, 2021 and December 31, 2020, Synovus had a variation margin of $81.8 million and $162.7 million respectively, each reducing the derivative liability.

The following table reflects the notional amount and fair value of derivative instruments included on the consolidated balance sheets.

Synovus also provides foreign currency exchange services, primarily forward contracts, with counterparties to allow commercial customers to mitigate exchange rate risk. Synovus covers its risk by entering into an offsetting foreign currency exchange forward contract. The notional amount of foreign currency exchange forwards was $18.4 million and $24.1 million at March 31, 2021 and December 31, 2020, respectively. The fair value of foreign currency exchange forwards was negligible at March 31, 2021 and December 31, 2020 due to the very short duration of these contracts.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Note 9 - Commitments and Contingencies

In the normal course of business, Synovus enters into commitments to extend credit such as loan commitments and letters of credit to meet the financing needs of its customers. Synovus uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. 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. Synovus also has commitments to fund certain low-income housing investments, solar energy, and CRA investments.

The contractual amount of these financial instruments represents Synovus' maximum credit risk should the counterparty draw upon the commitment, and should the counterparty subsequently fail to perform according to the terms of the contract. Since many of the commitments are expected to expire without being drawn upon, total commitment amounts do not necessarily represent future cash requirements. Additionally, certain commitments (primarily consumer) can generally be canceled by providing notice to the borrower.

The ACL associated with unfunded commitments and letters of credit is recorded within other liabilities on the consolidated balance sheets. At March 31, 2021, the ACL for unfunded commitments was $51.5 million, compared to a reserve of $47.8 million at December 31, 2020. Additionally, an immaterial amount of unearned fees relating to letters of credit are recorded within other liabilities on the consolidated balance sheets.

Synovus invests in certain LIHTC partnerships which are engaged in the development and operation of affordable multi-family housing pursuant to Section 42 of the Code. Additionally, Synovus invests in certain solar energy tax credit partnerships pursuant to Section 48 of the Code. Synovus typically acts as a limited partner in these investments and does not exert control over the operating or financial policies of the partnerships and as such, is not considered the primary beneficiary of the partnership. For certain of its LIHTC investments, Synovus provides financing during the construction and development of the properties and is at risk for the funded amount of its equity investment plus the outstanding amount of any construction loans in excess of the fair value of the collateral for the loan, but has no obligation to fund the operations or working capital of the partnerships and is not exposed to losses beyond Synovus’ investment. Synovus receives tax credits related to these investments which are subject to recapture by taxing authorities based on compliance provisions required to be met at the project level.

Synovus also invests in certain other CRA partnerships including SBIC programs. The SBIC is a program initiated by the SBA in 1958 to assist in the funding of small business loans.

Merchant Services

In accordance with credit and debit card association rules, Synovus provides merchant processing services for customers with a contractual arrangement under which certain sales and processing support are provided through an outside merchant services provider with Synovus owning the merchant contract relationship. In addition, Synovus sponsors various third-party MPS businesses that process credit and debit card transactions on behalf of merchants. In connection with these services, a liability may arise in the event of a billing dispute between the merchant and a cardholder that is ultimately resolved in the cardholder's favor. If the merchant defaults on its obligations, the cardholder, through its issuing bank, generally has until six months after the date of the transaction to present a chargeback to the MPS, which is primarily liable for any losses on covered transactions. However, if a sponsored MPS fails to meet its obligations, then Synovus, as the sponsor, could be held liable for the disputed amount. Synovus seeks to mitigate this risk through its contractual arrangements with the MPS and the merchants by withholding future settlements, retaining cash reserve accounts and/or obtaining other security. For the three months ended March 31, 2021 and 2020, Synovus and the sponsored entities processed and settled $26.03 billion and $18.37 billion of transactions, respectively.

Synovus covered chargebacks related to a particular sponsored MPS during 2019 and 2018 where the MPS’s cash reserve account was unavailable to support the chargebacks. As of March 31, 2021, the remaining amount, net of reserves, included in other assets and classified in NPAs, is $15.5 million, compared to $15.6 million at December 31, 2020. While Synovus has contractual protections to mitigate against loss, repayment of the amounts owed to Synovus will depend in large part upon the continued financial viability and/or valuation of the MPS.

Legal Proceedings

Synovus and its subsidiaries are subject to various legal proceedings, claims and disputes that arise in the ordinary course of its business. Additionally, in the ordinary course of business, Synovus and its subsidiaries are subject to regulatory and governmental examinations, information gathering requests, inquiries and investigations. Synovus, like many other financial institutions, has been the target of legal actions and other proceedings asserting claims for damages and related relief for losses. These actions include mortgage loan and other loan put-back claims, claims and counterclaims asserted by individual borrowers related to their loans, allegations of violations of state and federal laws and regulations relating to banking practices, and allegations related to Synovus' participation in government stimulus programs, including putative class action matters. In addition to actual damages, if Synovus does not prevail in such asserted legal actions, credit-related litigation could result in additional write-downs or charge-offs of assets, which could adversely affect Synovus' results of operations during the period in which the write-down or charge-off were to occur.

Synovus carefully examines and considers each legal matter, and, in those situations where Synovus determines that a particular legal matter presents loss contingencies that are both probable and reasonably estimable, Synovus establishes an appropriate reserve. An event is considered to be probable if the future event is likely to occur. While the final outcome of any legal proceeding is inherently uncertain, based on the information currently available, advice of counsel and available insurance coverage, management believes that the amounts accrued with respect to legal matters as of March 31, 2021 are adequate. The actual costs of resolving legal claims may be higher or lower than the amounts accrued.

In addition, where Synovus determines that there is a reasonable possibility of a loss in respect of legal matters, Synovus considers whether it is able to estimate the total reasonably possible loss or range of loss. An event is “reasonably possible” if “the chance of the future event or events occurring is more than remote but less than likely.” An event is “remote” if “the chance of the future event or events occurring is more than slight but less than reasonably possible." In many situations, Synovus may be unable to estimate reasonably possible losses due to the preliminary nature of the legal matters, as well as a variety of other factors and uncertainties. For those legal matters where Synovus is able to estimate a range of reasonably possible losses, management currently estimates the aggregate range from our outstanding litigation is from zero to $5 million in excess of the amounts accrued, if any, related to those matters. This estimated aggregate range is based upon information currently available to Synovus, and the actual losses could prove to be lower or higher. As there are further developments in these legal matters, Synovus will reassess these matters, and the estimated range of reasonably possible losses may change as a result of this assessment. Based on Synovus' current knowledge and advice of counsel, management presently does not believe that the liabilities arising from these legal matters will have a material adverse effect on Synovus' consolidated financial condition, results of operations or cash flows. However, it is possible that the ultimate resolution of these legal matters could have a material adverse effect on Synovus' results of operations or financial condition for any particular period.

Synovus intends to vigorously pursue all available defenses to these legal matters, but will also consider other alternatives, including settlement, in situations where there is an opportunity to resolve such legal matters on terms that Synovus considers to be favorable, including in light of the continued expense and distraction of defending such legal matters. Synovus maintains insurance coverage, which may be available to cover legal fees, or potential losses that might be incurred in connection with such legal matters. The above-noted estimated range of reasonably possible losses does not take into consideration insurance coverage which may or may not be available for the respective legal matters.

Segment Reporting

Segment Reporting [Abstract]

Segment Reporting

Note 10 - Segment Reporting

Synovus' business segments are based on the products and services provided or the customers served and reflect the manner in which financial information is evaluated by the chief operating decision makers. Synovus has three major reportable business segments: Community Banking, Wholesale Banking, and Financial Management Services (FMS), with functional activities such as treasury, technology, operations, marketing, finance, enterprise risk, legal, human resources, corporate communications, executive management, among others, included in Treasury and Corporate Other.

Business segment results are determined based upon Synovus' management reporting system, which assigns balance sheet and income statement items to each of the business segments. Certain assets, liabilities, revenues, and expenses not allocated or attributable to a particular business segment are included in Treasury and Corporate Other. Synovus's third-party lending consumer loans and held for sale loans as well as PPP loans are included in Treasury and Corporate Other. The management accounting policies and processes utilized in compiling segment financial information are highly subjective and, unlike financial accounting, are not based on authoritative guidance similar to GAAP. As a result, reported segment results are not necessarily comparable with similar information reported by other financial institutions.

The Community Banking business segment serves customers using a relationship-based approach through its branch, ATM, commercial, and private wealth network in addition to mobile, Internet, and telephone banking. This segment primarily provides individual, small business, and corporate customers with an array of comprehensive banking products and services including commercial, home equity, and other consumer loans, credit and debit cards, and deposit accounts.

The Wholesale Banking business segment serves primarily larger corporate customers by providing commercial lending and deposit services through specialty teams including middle market, CRE, senior housing, national accounts, premium finance, structured lending, healthcare, asset-based lending, and community investment capital.

The Financial Management Services (FMS) business segment serves its customers by providing mortgage and trust services and also specializing in professional portfolio management for fixed-income securities, investment banking, the execution of securities transactions as a broker/dealer, asset management, financial planning, and family office services, as well as the provision of individual investment advice on equity and other securities.

Synovus uses a centralized FTP methodology to attribute appropriate net interest income to the business segments. The intent of the FTP methodology is to transfer interest rate risk from the business segments by providing matched duration funding of assets and liabilities. The result is to centralize the financial impact, management, and reporting of interest rate risk in the Treasury and Corporate Other function where it can be centrally monitored and managed. Treasury and Corporate Other includes certain assets and/or liabilities managed within that function. Additionally, Treasury and Corporate Other also charges (credits) an internal cost of funds for assets held in (or pays for funding provided by) each business segment. The process for determining FTP is based on a number of factors and assumptions, including prevailing market interest rates, the expected lives of various assets and liabilities, and the Company's broader funding profile.

The following tables present certain financial information for each reportable business segment for the three months ended March 31, 2021 and 2020. The application and development of management reporting methodologies is a dynamic process and is subject to periodic enhancements. As these enhancements are made, financial results presented by each reportable business segment may be periodically revised.

Accounting Policies [Abstract]

Reclassifications

Prior periods' consolidated financial statements are reclassified whenever necessary to conform to the current periods' presentation.

Use of Estimates in the Preparation of Financial Statements

In preparing the consolidated financial statements in accordance with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the respective consolidated balance sheets and the reported amounts of revenues and expenses for the periods presented. Actual results could differ significantly from those estimates.

Material estimates that are particularly susceptible to change relate to the determination of the ACL; estimates of fair value; income taxes; and contingent liabilities.

Recently Adopted Accounting Standards and Recently Issued Accounting Standards Not Yet Adopted

Recently Adopted Accounting Standards

ASU 2020-08, Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable Fees and Other Costs. The guidance in this ASU pertains to the shortened amortization period for certain purchased callable debt securities held at a premium, which premium is amortized to the earliest call date in accordance with ASC 310-20-25-33, and clarifies that an entity should reevaluate whether a callable debt security is within the scope of paragraph 310-20-25-33 for each reporting period. The amendments in this ASU are effective for fiscal years beginning after December 15, 2020. Synovus adopted ASU 2020-08 effective January 1, 2021 with no material impact to the unaudited consolidated financial statements.

ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. In December 2019, the FASB issued ASU 2019-12 to simplify and reduce complexities when accounting for income taxes by removing certain exceptions.
