CHAIRMAN'S MESSAGE

TO OUR SHAREHOLDERS

Over the past year, I've thought frequently of the story I heard a while back about an inscription found outside a small church in Leicestershire, England:

"In the year 1653, when all things sacred were either demolished or profaned, Sir Robert Shirley built this church, whose singular praise it is to have done the best of things in the worst of times, and hoped them in the most calamitous."

By any measure, 2020 was a calamitous time for many. Most of us approached 2020 with great optimism: In recent years, it may have been the exceptional strategic plan or aspirational forecast that had not embraced the double meaning suggested by "2020" to convey a sense of vision and focus. But as if with the flip of a switch, in mid-March the global COVID-19 pandemic upended those plans, and with unprecedented immediacy broad swaths of the U.S. economy were locked down or shut in.

In addition to the pandemic, we saw record-breaking wildfires in California, a major earthquake in ourheadquarters state of Utah, and so many hurricanes along the Gulf Coast that, after exhausting the English alphabet, a third of the Greek alphabet was consumed in naming them. And as a nation, and in our local communities, we found ourselves reflecting deeply on the need for a much greater commitment to racial equity and to ensuring that all Americans have access to the tools needed to succeed in our economy after the series of racially charged events that culminated with the tragic killing of George Floyd in Minneapolis last summer.

As bankers, we've never experienced a time when so many of our clients were in such great need of immediate help as was the case in 2020. I was incredibly proud of our team, who rose to the challenge of doing "the best of things in the worst of times," and of providing hope during such a tumultuous period. This past year testedour ability to respond to challenges in our communities, and to demonstrate our responsibility to provide leadership in delivering solutions.

To its credit, the U.S. Congress recognized the urgency of providing economic aid to businesses and individuals impacted by the pandemic, and almost immediately at its onset provided important tools for banks to use in assisting clients. The Coronavirus Aid, Relief, and Economic Security (CARES) Act was signed into law on March 27, 2020. At a total cost of $2.2 trillion, it was by far the largest economic stimulus initiative in our nation's history, amounting to about 10% of U.S. GDP. Included in the bill was $300 billion in one-time payments to individuals, $260 billion in increased unemployment benefits, and $840 billion in loans and grants to corporations and local governments.

The CARES Act also included $350 billion (later increased to $669 billion) in forgivable, fully government-guaranteed Paycheck Protection Program (PPP) loans for small businesses. The PPP program was designed to help small businesses pay their employees and meet other pressing financial needs while their businesses were adversely affected by the pandemic, by providing for loan forgiveness if the proceeds were used to meet specific needs.

remotely. One visiting our nearly vacant headquarters offices during those early weeks of the pandemic would never have guessed that a giant home-based invisible army of bankers was working through tens of thousands of applications, delivering help to their clients.

Three days after the CARES Act was signed into law, and even before the program's final rules were in place, we'd begun training nearly 2,000 of our front-line bankers, encouraging them to reach out to their clients and to prospective clients in need of help. Within a week, we began taking loan applications, quickly introducing a digital application available via our websites and on mobile devices.

Small businesses have always been one of our most important target market segments, and we understood the importance of going the extra mile to reach out to them during an incredibly stressful time. It was fascinating to witness how various competitors responded to the opportunity to deliver PPP aid to small businesses. At least two of the nation's largest banks at one time or another posted notices on their websites suggesting that clients in need of a PPP loan might want to talk to another bank. Another initially indicated that it would accept applications only from clients who were existing borrowers.

This was all being done a mere two weeks after moving thousands of our office-based bankers to working from home, and it was a great test of our ability to work

Our own approach was to unite great technology with great bankers, and in so doing to provide an experience to clients that combined the simplicity and elegance of

a digital application with the assurance and coaching of a helpful banker focused on seeing that client expectations were exceeded.

It was a huge success: By the time the "2020 round" of the PPP program concluded, Zions Bancorporation was the ninth largest PPP lender in the nation, providing more than $7 billion of loans to over 47,000 businesses, over 30% of which were new clients. In total, our aggregate PPP lending in 2020 equaled 24% of the volume produced by the nation's largest bank - a company 41 times our asset size.

We were particularly proud of the fact that approximately one-third of the dollars loaned were to businesses in low-to-moderate income census tracts, or where minority groups constitute over 50% of the population. This was the result, in part, of outreach to numerous Black, Hispanic, and Asian/Pacific Islander chambers of commerce throughout our market area. Seventy percent of our loans were to businesses with fewer than tenemployees, and the median size of the loans we made was $33,200.

Our success with the PPP program generated approximately $220 million in fee-based revenue (all of which, under accounting rules, is being deferred and recognized as

was thrilled! When I asked her for her 2019 taxes, she started to cry and said she could not do them as she has no money to pay her accountant. I knew then that

I needed to do everything in my power to get this application through and done quickly.

The PPP experience served to validate our belief that the future of banking businesses and their owners - a focal point of our long-term strategy - will continue to be grounded in the intersection of technology and strong banker-to-client relationships.

I want to share a sampling of a few of the stories, letters and emails I received during the course of the PPP campaign. I include them because they communicate, more eloquently and convincingly than I can, why we believe building strong relationships is critical to our success. Clients' names have been changed, where appropriate:

FROM MIKE BUICH, OWNER OF TADICH GRILL IN SAN FRANCISCO, CA: "Since [we've had a] long relationship with [a major national bank], I was confident 'my bank' would take care of me … My hope for assistance quickly turned to frustration when I realized [they] were not processing applications nor providing any direction or answers to my inquiries. On April 13, 2020 I called Zions Bank … and was immediately transferred to Mel Hugentobler, Vice President and Branch Manager, who took personal interest in my plight, and personally handled the application process for the PPP loan … My experience with Zions Bank and the PPP application was seamless. I know your employees have been working long hours, often dealing with clients that are scared, frustrated, and angry, however I wanted to take this time to give you some positive feedback and assure you that their hard work did pay off. I always felt like we were a team working together towards a common goal."

FROM NANCY PEARCE, A ZIONS BANK BRANCH MANAGER IN BOUNTIFUL, UT: "Jane Anders is a single divorced woman who has her own photography business. Her business came to a screaming halt with the pandemic. She originally sent in an incomplete PPP application. I called Jane, and she was surprised to hear from me as she had heard the [PPP money was exhausted]. I assured her there was money available and I would be happy to help her if she still wanted to pursue it. She

"After spending all day Friday with numerous obstacles of expired registration, unfiled 2019 taxes, and account issues I was able to help Jane and finally get her application submitted. With the assistance of Shelly Johnson, we were able to quickly get it moved through the queue. When I informed Jane Friday night she replied, 'Oh my goodness! Best news EVER! I cannot thank you enough. Just know that all your hard work and reopening my application is actually putting groceries in my fridge today.'"

FROM THE OWNER OF A HOSPICE CARE BUSINESS IN BURBANK, CA: "It is with great gratitude that I write this letter of appreciation to Ms. Nhienle Mac [a relationship banker in Pasadena] for the exemplary service I received from her last week.

"I am a Small Business owner and … I was so frustrated with the process of trying to get a PPP loan from [a major national] bank. When I submitted my request for the loan, because of the numerous applications and [the] huge scale of the whole system, I didn't hear anything from the bank. Waiting and waiting and it's like it went into a dark hole. I almost gave up, until a friend of mine referred me to California Bank & Trust and I spoke directly to Ms. Nhienle Mac. It was a surprise that I finally was able to speak to a live person in the bank.

"Ms. Nhienle Mac's enthusiastic, natural, and attentive tone of voice while on the phone helped me feel comfortable during our conversation. She answered my questions with sincerity and honesty that made me feel satisfied in moving forward with the application ... She worked on my loan tirelessly and got it done so swiftly. I got my PPP loan approval in less than 72 hours. Ms. Mac's performance surpassed my expectations. [It's] hard to find words to describe the positive experience I had with her. I am a Registered Nurse, and as part of the health care workers during this COVID-19 global pandemic crisis, we are being hailed as 'heroes.' For me and for sure to many other small business applicants she is helping now, Ms. Nheinle Mac is a true 'superhero.'"

FROM DR. JEFF PATRICIAN, A DENTIST IN BOULDER, CO: "I want to say how lucky I am to have a banking relationship with Vectra and the entire team, specifically Drew Britton [a business banker in Boulder]. Over close to a decade I have depended on Vectra for my business and personal banking needs … That relationship has now saved my office during this disaster. I read horror stories online of dentists who bank with the evil faceless Big Boys finding themselves thrown to the curb and scrambling completely on their own.

"I want to thank Drew and everyone involved for their tireless efforts in the last few weeks. This was a heck of a test you were given, but your tremendous skill with what you do, combined with an inner sense of care for the people you serve … has saved my business, and surely many more. I know how long and hard you've been working, and I wish there was a way I could show my appreciation. This letter will have to do for now. Please feel free to pass it along to people who will want to know."

AND A TWEET FROM ONE OF OUR NEW UTAH CLIENTS, in response to Shark Tank's Mark Cuban, who asked for both positive and negative PPP experiences:

After being with @[large credit union] for 17 years, they wouldn't even process our #PPPLoans app. I called @ZionsBank and they were AWESOME! I can't recommend them more highly! Very hands-on. We will definitely be sending all our deposit business to #zionsbank. What a phenomenal experience!

One of my favorite stories to come out of the PPP experience was the client in Idaho's Wood River Valley who took out a newspaper ad [see below], at his/her own expense, to laud Zions Bank for its performance in delivering PPP aid.

We helped our clients in other ways, as well. We provided payment deferrals or modifications on loans totaling $4.3 billion to clients impacted by COVID-19. At the end of the year, only 1% had payments that were past due 90 days or more. We also participated in the Main Street Lending Program, a facility provided by the Federal Reserve System to assist certain middle market borrowers access the credit markets, originating $148 million in such deals during the year.

As you can imagine, I'm proud beyond words of the work of so many of our bankers - some of whom worked virtually around the clock, at home, for days on end - in helping many thousands of businesses. Of the many heroes we've read about in recent months, they certainly rank among them for their role in helping to rescue these businesses. They truly did the best of things in the worst of times, and provided hope in the most calamitous.

FINANCIAL RESULTS

The bank's financial results in 2020 were materially impacted by the pandemic, which led the Federal Reserve to more vigorously promote a "zero interest rate policy" that adversely affected our primary revenue source - net interest income. The pandemic also resulted in a substantial addition to the bank's loan loss reserves due to concerns about our borrowers' ability to withstand the pandemic's impact on their businesses and their personal financial situations.

Net income available to common shareholders totaled $505 million, or $3.02 per share, a reduction from the prior year's results of $782 million, or $4.16 per share. The most notable factor adversely impacting our performance in 2020 was a provision for credit losses of $414 million, as compared with $39 million in 2019. Aside from the pandemic, the increased provision was also precipitated in part by a new accounting standard that became effective at the beginning of 2020, known as Current Expected Credit Loss, or CECL. This standard, in many cases, requires larger reserves than previously, as reserves must be established for losses expected during the life of a loan, as opposed to only reserving for losses currently inherent in our loans under the prior standard.

Actual net loan and lease charge-offs during the year were $105 million or 0.22% of average (non-PPP) loans, up from $37 million or 0.08% of average loans in 2019.

PPNR-NCOs. This measure employs adjusted PPNR (which we reconcile to Generally Accepted Accounting Principles, or GAAP, in our financial statements), which adjusts tax-exempt revenue to its taxable equivalent value and further adjusts for non-recurring expenses. In 2020, the most significant adjustment was a one-time expense of $28 million to fully terminate our dormant defined-benefit pension plan.

PPNR-NCOs also substitutes actual net charge-offs for the provision for credit losses. Net charge-offs is a measure of actual losses during the period, while the provision for credit losses results from a forecast of future losses that is subject to the increased imprecision (certainly a feature of any forecast) inherent with the implementation of the CECL accounting standard.

When measured by our PPNR-NCOs results, 2020 was a respectable year, considering the impact of the pandemic. PPNR-NCOs was $1.038 billion, a 7.7% reduction from $1.125 billion in 2019 - a year in which realized credit losses were exceptionally low.

The pandemic had a sizable impact on loans and deposits. Average non-PPP loans increased only 0.5%, to $48.5 billion, and non-PPP loans at year end were down $805 million or 1.7%, and would have been down further but for $550 million, or 4.8%, growth in commercial real estate loans, and strong growth of $558 million or 23.3% in municipal loans.

Internally, and for many of our management incentive programs, we focus on a measure we refer to as adjusted Pre-provision Net Revenue, less Net Charge-offs, or

This enormous increase in money supply was accomplished through the open market purchase of securities, which injected immense amounts of cash into the economy. All that cash must end up somewhere, and much of it appears to be in deposit accounts on banks' balance sheets.

The extraordinary economic stimulus consisted of both federal government fiscal policy, which produced a $3.1 trillion deficit equal to about 15% of GDP, and an equal dose of central bank money creation. The Federal Reserve System's balance sheet, which had already swollen from $0.9 trillion prior to the 2008 financial crisis to a pre-pandemic level of $4.3 trillion, was further inflated to $7.4 trillion by the end of 2020. To put this $3.1 trillion increase in money supply in context, a $3.1 trillion stack of dollar bills would reach to the moon; 3.1 trillion gallons of water would fill Lake Powell - a massive 185-mile-long reservoir that straddles the Utah-Arizona border and averages 132 feet in depth.

DEPOSIT GROWTH

Average balances

The purchase of securities by the Fed boosts the market value of those securities and, inversely, creates downward pressure on interest rates: the average 30-year Treasury rate in 2020, at a mere 1.56%, was a full percentage point lower than in 2019; the average 3-month Treasury rate dropped one and three quarters percentage points to 0.36% in 2020, from 2.11% in 2019.

All of this was wonderful for our residential mortgage business - total mortgage production increased 29% from 2019 to $3.5 billion, with another $1.5 billion in the pipeline at the end of December. The profit margins on mortgages we sold increased as well, resulting in an increase in loan sales income of more than 220% when compared with 2019. But the lower interest rates were decidedly less helpful to our net interest margin, which decreased to 3.15% in 2020, from 3.54% in 2019. Average earning asset yields fell 80 basis points (hundredths of a percentage point) as maturing loans were refinanced at current lower rates, while the total cost of deposits and interest-bearing liabilities dropped 45 basis points. With such a large volume of noninterest-bearing demand deposits, and with other deposit rates nearing zero, margin compression is a great challenge in such a low rate environment.

Our taxable-equivalent net interest income, which was negatively impacted by this margin pressure, was greatly

aided by the amortization of deferred PPP revenue, which contributed $148 million to 2020 pretax results. Noninterest income rose 2.1% to $574 million, with customer-related fee income - which excludes dividend income, securities gains and fair value adjustments on derivatives - increasing 4.6% to $549 million. Weakness in retail banking fees and card income was offset by the aforementioned strength in mortgage banking income, which more than tripled during the year, the result of the low interest rate environment and the introduction in 2019 of a very appealing digital mortgage application.

Noninterest expense was well controlled. Total noninterest expense was $1.7 billion, down 2.2% from 2019. When adjusted for certain non-operating expenses, such as the termination of our defined-benefit pension plan, severance, and restructuring costs in both years, noninterest expense decreased $31 million, or $61 million when further adjusted for the one-time $30 million donation made to the Bank's charitable foundation in conjunction with our success in the PPP program.

Our Supply Chain Management group also produced strong results in 2020, with realized savings of $27.5 million, arising from 81 different projects.

We continued to rationalize our branch network in 2020, closing 14 branches and consolidating their accounts and people into other branches, while rightsizing five other branches. At the same time, we opened two new branches during the year in growing markets. While we will continue to constantly evaluate and optimize our branch network, these physical locations remain a vitally important component of our strategy to locate empowered, well-trained, and long-tenured relationship bankers close to our clients.

CREDIT QUALITY

In late 2019, we had anticipated earnings pressure from a low interest rate environment during 2020, and implemented a staff reduction program that, when combined with other net workforce reductions accomplished through attrition and associated with lower branch transactional activity, reduced our full-time equivalent employee count by 510, and contributed to a $54 million, or 4.7%, reduction in salary and benefits expense. Travel, business development, and public relations expenses were also down $21 million, or 75.9%, because of the pandemic.

The strength and resiliency of our borrowing clients, combined with the impact of a great deal of government stimulus and high-quality asset selection, resulted in relatively healthy credit results in 2020, given the backdrop of the pandemic.

We identified approximately $4 billion of non-PPP loans extended to borrowers in ten industries we deemed to have elevated risk due to the pandemic. We conducted extensive reviews of the significant loans in these portfolios and continue to carefully

Our ability to reduce staffing levels has benefited from a focus on applying robotic automation to a wide range of tasks. In late 2018, we established a Business Process Automation Center of Excellence, with a dedicated team that has implemented over 240 automation solutions, reducing human error, improving consistency, and enhancing competitiveness by reducing costs. In 2020, 281,000 manual hours were eliminated, and the team has established an ambitious goal to eliminate an additional 1 million hours by 2022.

I've told Ken Collins, an exceptional executive who oversees much of this process automation effort, that the bank of the future will have a person, a dog, and a computer. The

monitor developments in our clients' businesses. While a higher proportion of these businesses availed themselves of temporary relief through payment deferral programs, there was almost always a strong secondary source of repayment, and 98% of the loans were secured by collateral, generally with real estate and with a median loan-to-value ratio of 53%.

Non-performing asset levels increased during the year, from 0.51% of loans, leases and other real estate owned at the end of 2019 to 0.69% at the end of 2020, but remained at very acceptable levels. Classified loans, those with weaknesses that, if not mitigated, could lead to loss, doubled in 2020, primarily among borrowers in the high-risk COVID-19 industries.

CAPITAL AND LIQUIDITY MANAGEMENT

We finished the year with a strong capital position, with a regulatory Common Equity Tier 1 ratio of 10.8%, up from 10.2% a year ago. Our Tier 1 Leverage ratio declined to 8.3%, from 9.2%, as a result of the strong deposit growth we experienced, and the coinciding increase in high-quality liquid assets.

As pandemic-related concerns produced a sharp decline in equity prices - including our own common share price - throughout the spring, 29.2 million of our ZIONW warrants, issued ten years ago in the aftermath of the financial crisis, expired "out of the money." While this produced a loss for holders of the warrants (myself included!), it was a boon for the company and its common shareholders, as it eliminated over eight million shares from our fully diluted share count. While we purchased 1.7 million shares of our common stock in the open market during the first quarter, we suspended any share buybacks for the remainder of the year after the onset of the pandemic, while maintaining our common dividend at its existing level.

Our balance sheet liquidity increased sharply during the year. At the end of 2019, interest-earning money market investments and securities totaling $15.7 billion comprised 23% of our total assets. By the end of 2020, these liquid assets had increased to $23.5 billion, constituting 29% of total assets. We've maintained a reasonably short duration in our securities portfolio. We believe that a persistent negative interest rate environment is unlikely,and that our downside risk in such a scenario is very limited, while our models indicate that a 100 basis point increase in rates would result in a 9% increase in net interest income, and a 200 basis point increase would result in an 18% rise in such revenue. We continue to believe that the government's posture toward fiscal policy, when combined with the immense amount of liquidity created through very accommodating monetary policy in recent years, creates an environment in which we would expect to see higher levels of inflation - and thus interest rates - in the years ahead.

OUR TECHNOLOGY JOURNEY

We continue to make substantial investments in technology, to ensure that we'll be capable of competing in a world that's become increasingly digital. As noted, we're strong believers in the symbiotic combination of great bankers and great technology. The investments we're making and the projects we've undertaken will allow us to create exceptional experiences for our clients and provide bankers with the products and tools they need to succeed.

Two of our primary projects, the replacement of our core loan and deposit systems (FutureCore), and the replacement of our online and mobile client-facing applications, experienced moderate setbacks due to the pandemic this past year. Work being performed offshore, in particular, was slowed or brought back to the U.S. primarily due to security concerns as contractors moved from working in cleanrooms to working in living rooms.

We're nevertheless proceeding at full speed to complete these two major projects, with the final release of FutureCore - a new and modern deposit system - slated for installation in early 2023; and with the new mobile and online platform beginning its rollout in the first quarter of 2021 with an initial implementation at National Bank of Arizona.

The risk of cyberattacks and data theft or compromise continues to escalate each year, as does our response. Over the past three years we have nearly tripled the size of our cybersecurity team, with a major increase in our associated investment in tools to prevent and detect data and network intrusions. Over that same period, we have increased the number of daily cybersecurity

"signals" or data sources we process and monitor by more than tenfold to secure our systems against this increasing threat.

In addition to the rapid deployment of a digital solution for PPP loans, a sampling of some of our achievements in 2020 included:

• › The launch of a New Accounts Opening Platform for our Treasury Management Select product, streamlining the process of opening new accounts for smaller treasury management clients. It was used to open over 400 new treasury management accounts subsequent to its launch in the fall.

• › The redesign and launch of a digital small business loan application, using the platform we built for the PPP program, and designed to speed the underwriting and processing of unsecured small business loans of under $50,000, and secured loans of up to $175,000.

• › The implementation of our Intelligent Real-time Information System (IRIS), which uses machine learningto help bankers identify solutions for clients. Launched in August with 630 users, it will be rolled out to 3,200 bankers over the next few months.

• › The launch of our Mobile Banker project, equipping hundreds of bankers with iPads that allow them to connect to client data while on calls, and to provide real-time solutions while meeting with clients.

• › The introduction of an online scheduler, allowing clients to schedule appointments with their branch-based bankers, either in the office or via videoconference - on their mobile phones.

• › The launch of a new Application Programming Interface, or API, platform, allowing for faster integration between our core systems and other applications.

• › The completion of a branch teller "capture" project, modernizing the manner in which deposited item information is captured at the point of deposit, eliminating the need for a deposit slip and dramatically reducing balancing and reconciliation issues.

We expect that the investments we're making in foundational technology and digital tools will keep us at the forefront of the banking industry in providing both our bankers and our clients with the capabilities and products they need, and with elegant experiences interacting with us in the years ahead.

Beyond the pandemic, 2020 was marked by an increased awareness throughout our nation of the need to raise our commitment, both institutionally and individually, to inclusiveness. At Zions Bancorporation, we're committed to ensuring this takes place in three areas: in theworkforce, in the workplace, and in the marketplace, in an effort we're calling, "Everyone Counts."

Following the tragic murder of George Floyd, we spent a great deal of time throughout the bank listening to colleagues from minority communities, with the objective of better understanding their hopes and challenges. I expressed my belief that tolerance should never be our objective; none of us aspires to be tolerated. We need to move beyond tolerance and form real friendships with those outside our usual circles and do all we can to help them succeed.

In this spirit, we expanded our company-wide Diversity, Equity and Inclusion (DEI) Council to advise the bank's management on steps we can take to ensure that we're a truly great place for all of our employees to work. Among the objectives we've established are expanding diversity training and ensuring that every new employee participates in it; including DEI questions in our periodic employee surveys; and seeking out more diverse candidates in our recruiting efforts. We've developed a

supplier diversity program, with the goal of expanding the list of diverse suppliers with whom we currently do business.

We also conducted, as we've done for a number of years, a study with the help of an independent third party to review equity in employee compensation. We found that, after adjusting for relevant variables including education, experience and geography, women are paid, on average, above 99% of what men are paid, and minorities are paid above 98% of what non-minorities earn. In a relatively few cases we identified outlier situations that have subsequently been addressed. We're committed to continue this focus on ensuring that Zions Bancorporation has a workplace where all are treated fairly in accordance with their qualifications and abilities, and that it's a place where "everyone counts."

I'm especially determined that we will do all in our power to make a difference for women and minority-owned businesses in the marketplace. Our most potent tool in creating positive change is to put our balance sheet and our bankers to work in funding the capital needs of deserving, underrepresented entrepreneurs. We're working with our regulators at the Office of the Comptroller of the Currency in an effort they're calling Project REACh to develop innovative and prudent methods for providing greater volumes of credit to these small business owners using both conventional and U.S. Small Business Administration (SBA) guaranteed loans. We have a great opportunity to put our small business banking capabilities to work in better serving these communities.

We've also announced a partnership with Unity National Bank, a Black-owned community bank headquartered in Houston, Texas, to provide equity capital. More importantly, we'll be providing Unity National with consulting in compliance and risk; and training, by reserving space in our Banker Development Program for one of their bankers.

The events of this past summer brought tragedy to one of our great bankers, Angela Underwood, a most talented regional manager for California Bank & Trust in California's Antelope Valley, and a woman who has very capably served her community in a number of capacities, including as deputy mayor of the city ofLancaster. During the nation-wide unrest that followed the killing of George Floyd, Angela's brother, Patrick, was shot and killed while protecting a Department of Homeland Security building in Oakland. As we've worked on creating a more equal and inclusive society this year, I've thought often of my friend Angela and her late brother, Patrick, two extraordinary Black citizens who are frequent reminders to me of why this work is so important.

WHAT THE PRESENT MAY TEACH US ABOUT THE FUTURE

One of the pandemic's not-so-minor miracles was the fact that the videoconferencing technology we and so many other businesses used to quickly pivot to working from home was so recently developed and deployed. In our case, we'd made Microsoft Teams® software available to employees in late 2019, only months before it became critical to our ability to function. By the end of the year, we were supporting 3.7 million monthly Teams® interactions.

It's an open question as to how the capabilities we've developed will change the way we work and interact with others. I expect it will allow greater flexibility for occasional work from home for many of us. Long before the pandemic, we'd had a number of employees working remotely, including many of our customer care center employees and some of our technologists.

I also expect that we'll see a reduction in business travel; there are many meetings that simply don't warrant the cost and the travel time required to show up in person now that "virtual" participation has become a good substitute for being physically present.

At the same time, we've seen that it's a real challenge, especially for newly hired employees, to develop the networks and relationships that are critical in our own, and most other businesses if we're not interacting with the people we work with in informal settings - in hallways, break rooms and elevators.

During 2020, we broke ground on two new significant building projects - a new headquarters facility for our Vectra Bank Colorado affiliate bank in Denver and a new technology and innovation campus in the Salt Lake Valley. In both cases, we're consolidating employees

located in multiple locations into more efficient space in a single building. Our technology campus, for instance, will reduce by 20% the space we currently occupy in a dozen different buildings, and will do so in a building that's substantially more energy-efficient and inviting.

Certainly, the digitalization of banking will continue. It will allow all of us to reduce costs and provide greater convenience and access to our clients. We currently average over 85 million mobile and online banking logins annually - creating substantial savings relative to the alternative of providing service in a branch or by telephone. At the same time, when a client is frustrated, or needs coaching with respect to a solution, there's no good substitute for a well-trained, highly qualified banker. Relationships still count. I believe that's not likely to change anytime soon.

As I write this letter, we're delivering the second round of PPP loans to eligible businesses, with $284.5 billion in funding included in a coronavirus relief bill passed by Congress in late December. The SBA opened its web portal to accept applications submitted through participating banks in mid-January, and in its interim report on results through February 15, 2021, Zions Bancorporation was listed as the nation's sixth largest PPP lender. Our bankers are at it again!

Our support of small and middle-market businesses led Greenwich Associates, a leading global financial services research organization, to name Zions Bancorporation as one of only a small number of "Standout Commercial Banks" amid the crisis for the way our people went the

After conducting more than 23,000 interviews with small and middle market businesses, resulting in enough data to evaluate more than 600 banks, Greenwich Associates also awarded Zions Bancorporation 15 "Excellence" awards in a variety of categories - the sixth most of any bank in the nation in 2020.

Finally, I want to express my appreciation to a long-time member of our Board of Directors who retired from his service with us this past year. During Jerry C. Atkin's 27 years as a board member he consistently challenged our thinking and added an abundance of common sense to our discourse. He also added the perspective of the kind of individual we seek out as a client - someone who worked hard over several decades to build a very small family-owned business - SkyWest Airlines - into a national leader in its field. We'll greatly miss Jerry's wisdom and good humor. At the same time, we were extremely pleased to welcome Claire A. Huang to our board. Claire brings us deep experience in financial services marketing with several of the nation's leading banks and brokerage firms. We're delighted to have her with us!

My thanks to each of you as shareholders in Zions Bancorporation. You have every reason to be proud to be associated with one of the most extraordinary teams of bankers in the industry. We look forward with you to a new year that will, I hope, see a recovering economy and a brighter outlook - especially for businesses and individuals who've been particularly hard-hit by the pandemic. The future is very bright, and we appreciate your support in helping us to capitalize on the opportunities that lie ahead of us.

Sincerely,
