Community roots, lasting impact

Since 2006, Signature Bank has supported more than 1,000 organizations while strengthening the communities it serves


When Signature Bank was founded in 2006, its mission centered on building meaningful relationships with business owners and entrepreneurs. But from the beginning, our founders also believed a strong bank should contribute to something larger than its balance sheet.

Communities thrive when businesses, nonprofits and community organizations work together. Over the past two decades, Signature Bank has embraced that responsibility by supporting organizations that expand opportunity, strengthen neighborhoods and help individuals build brighter futures.

A philosophy rooted in relationships

Founders Mick O’Rourke, Kevin Bastuga and Bryan Duncan built the bank on the idea that relationships should extend beyond transactions. That same principle shapes how the bank engages with the communities where its clients and employees live and work.

“From the beginning, we wanted Signature to be the kind of bank that shows up for the communities it serves,” said Bryan Duncan, Co-Founder and Executive Vice President. “When the communities around us grow stronger, the businesses we serve grow stronger too. That’s why supporting local organizations has never been separate from our work – it’s part of how we build lasting relationships.”

Over the years, Signature Bank’s charitable giving has touched a wide range of causes, from education and youth development to disability services and food access. Many of those efforts have grown into long-standing partnerships built through consistent involvement and a shared commitment to making a difference.

Meaningful partnerships close to home

Some of those partnerships have become especially personal. Misericordia Heart of Mercy, a Chicago nonprofit providing residential and support services for children and adults with intellectual and developmental disabilities, has long been close to the team’s heart. Employees have supported Misericordia through financial contributions, volunteer efforts and its Candy Days fundraiser, with the downtown branch serving as a counting station where volunteers gather, track donations and share a meal together.

The Evans Scholars Foundation, which provides full college scholarships and housing to hardworking caddies with financial need, holds that same kind of deep personal significance. The connection runs deep: several employees are proud Evans Scholars themselves, and Mick O’Rourke, President and CEO of Signature Bank, serves as Treasurer of the Western Golf Association/Evans Scholars Foundation. The team regularly participates in WGA and Evans Scholars Foundation fundraising events, including golf invitationals and the annual Green Coat Gala, helping support scholarships for students across the country.


“Education opens doors that can change the trajectory of someone’s life,” said O’Rourke. “Organizations like the Evans Scholars Foundation create those opportunities. When we support causes like this, we are investing in future leaders, and that has always felt like the right thing to do.”

Expanding the impact

Signature Bank’s community presence extends well beyond its closest partnerships. The bank has been a long-time supporter of Big Shoulders Fund, which strengthens Chicago’s network of Catholic schools in underserved communities through scholarships, school support and volunteer efforts. Employees have also participated in Mercy Home for Boys & Girls Job Skills Seminars, helping young people prepare for interviews and future careers. And over the years, charity golf tournaments have offered another way to give back, with employees supporting organizations such as Tunnel to Towers Foundation, the Alzheimer’s Association, Boys Hope Girls Hope and others.

A culture of giving back

“Some of the most rewarding moments for our team come from volunteering together,” said Kevin Bastuga, Co-Founder and Executive Vice President. “When you spend time with the people these organizations serve, it reminds you why showing up in person matters.”

That sentiment extends well beyond leadership. Community involvement has become part of who the team is, showing up in countless ways across every branch and every season of the year, from organizing food and Thanksgiving donation drives for A Just Harvest Food Pantry and joining the Village of Niles spring community cleanup, to volunteering at Border Tails Rescue and so much more.

“Some of the most meaningful moments happen when employees come together for causes they care about,” said Michelle Greenwood, Vice President of Treasury Management and an active leader in many of the bank’s volunteer efforts. “Those efforts reflect the kind of team we have built here.”

Since 2006, Signature Bank has contributed more than $1.33 million in support across more than 1,000 organizations. Each contribution serves a different mission, but all share a common thread: strengthening the communities where the bank’s employees and clients live and work.

Continuing the commitment

In the past two decades, our bank has grown, but our underlying philosophy remains unchanged: success should be shared.

“The relationships we’ve built over the past two decades extend well beyond banking,” said O’Rourke. “Our clients are part of these communities, our employees raise their families here and the organizations we support help make these places stronger.”

Looking ahead, Signature Bank plans to continue investing in organizations that create meaningful impact, whether through financial support, volunteer service or long-term partnerships.

Because when a bank grows alongside the communities it serves, the benefits reach far beyond business. That was true in 2006, and it remains true today.

Esquire Financial Holdings, Inc. to Acquire Signature Bancorporation Inc., Expanding into the Chicago Banking Market

Strategic Acquisition of a Premier Chicago Commercial Banking Franchise to Enhance Growth, Diversification and Expand Litigation Vertical in Chicago

Jericho, NY & Rosemont, IL, March 12, 2026 – Esquire Financial Holdings, Inc. (NASDAQ: ESQ) (“Esquire”), the parent company of Esquire Bank, National Association and Signature Bancorporation, Inc. (“Signature”), the parent company of Signature Bank, jointly announced today that they have entered into a definitive merger agreement, pursuant to which Esquire will acquire Signature in an all-stock transaction. The combined company will have approximately $4.8 billion in assets at closing, joining Esquire’s established national verticals with Signature’s established Chicago commercial banking franchise, enhancing our continued industry leading performance and growth metrics.

Andrew C. Sagliocca, Vice Chairman, Chief Executive Officer and President of Esquire, said, “Signature’s leadership in the attractive Chicago market, best-in-class management team, and exceptional core funding provide Esquire with a strong platform for continued growth and expansion in the country’s third largest metropolitan area or MSA and one of the nation’s largest legal markets.  This merger is compelling on multiple levels. Financially, it enhances our operating profile, expands our resources, and diversifies our balance sheet while maintaining a robust capital position for continued expansion in our unique national litigation platform. Strategically, the combination brings together two institutions with highly complementary commercial banking operations and capabilities. Most importantly, it unites two highly talented management teams with deep client relationships and strong market expertise. We are thrilled to welcome Signature’s team, clients, and shareholders to Esquire.”

Mick O’Rourke, Co-Founder, Director, Chief Executive Officer, and President of Signature, said, “We are excited to announce a partnership that will benefit both institutions, our clients, and our shareholders, while also positioning us to work together towards the next chapter of our combined organization’s legacy. By bringing together Signature’s strong Midwest commercial banking franchise with Esquire’s national capabilities, we will have greater resources and expanded reach to support our clients as they grow. As we celebrate Signature’s 20th anniversary, this merger will provide our shareholders with enhanced liquidity and an opportunity to create greater value in the years ahead.”

Strategic Benefits

Expansion in the Chicago Market: Provides Esquire with a premier Chicago commercial banking franchise and talent in the country’s third largest MSA and fourth largest legal market where Esquire traditionally lacked presence while supporting continued growth in Esquire’s national litigation platform and expanding the resources and capabilities available to Signature’s clients in the Midwest.

Enhances Scale and Combines Complementary Strengths: The combined company will be strategically positioned for enhanced scale with improved opportunities for growth and profitability. Signature brings longstanding history of commercial and commercial real estate relationship banking in the Chicago market while Esquire is a national leader in the litigation vertical that seeks to expand its presence in the Chicago market as well as nationwide.  This creates opportunities to bring Esquire’s specialized capabilities to Signature clients while extending Signature’s commercial banking expertise across a broader platform.

Diversification to Drive Future Growth: Reduces Esquire’s litigation vertical loan and funding concentrations from approximately 70%+ to below 50%, supporting future accelerated growth in Chicago, the Midwest and nationwide.

Maintains Strong Profitability while Deploying Excess Capital: Signature’s high-performing commercial bank with strong low-cost core commercial deposits diversifies Esquire’s balance sheet while contributing significant earnings with strong performance metrics, generating a mid to high-teens IRR for the deployment of Esquire’s excess capital in the merger.

Prospects to Accelerate Shareholder Value Creation: Pro forma calculations of the combined company indicate GAAP EPS accretion of 23% for Esquire in 2027 with no associated revenue enhancement in the pro forma calculations. The transaction is approximately 11% accretive to Esquire’s Tangible Book Value. The transaction only assumes 5% cost savings as the value created in this merger is primarily driven by industry leading growth and performance metrics.  Esquire remains well capitalized with no associated capital raise.

Governance and Leadership

Each of the combined company’s and bank’s board of directors will consist of eleven directors, including nine directors from Esquire and two directors from Signature.

  • Leonard S. Caronia: Current Signature Chairman of the Board will join Esquire’s board of directors.
  • Michael G. O’Rourke: Current Signature Chief Executive Officer & President will join Esquire’s board of directors.

The combined company will be led by a well-respected management team with significant commercial banking experience.

  • Signature’s top three executives have entered into new employment agreements and will oversee commercial business development opportunities and operations in the Chicago market.
    • Michael G. O’Rourke: Current Signature Chief Executive Officer & President and post-merger President of Signature, a division of Esquire Bank. 
    • Bryan D. Duncan: Current Signature Executive Vice President and post-merger Executive Vice President of Signature, a division of Esquire Bank. 
    • Kevin Bastuga: Current Signature Executive Vice President and post-merger Executive Vice President of Signature, a division of Esquire Bank. 

Transaction Details

Under the terms of the merger agreement, shareholders of Signature will receive a fixed exchange ratio of 2.63 shares of Esquire common stock for each share of Signature common stock. The per share value equates to $260.48 for Signature shareholders based on the closing price of Esquire common stock on March 11, 2026, or approximately $348.4 million in aggregate transaction value.

The exchange ratio is subject to an adjustment based on the disposition value of certain Signature Bank loans with a total par value of approximately $70M (“Schedule A Loans”).  The adjusted Exchange Ratio at closing will be no higher than 2.80 and no lower than 2.50.  Signature has initiated a sale process and is expected to dispose of Schedule A Loans prior to closing.

The definitive merger agreement has been approved by the board of directors of each company. The transaction remains subject to regulatory approval, approval of Esquire and Signature shareholders, and other customary closing conditions. Pending these approvals, the transaction is anticipated to close in the third quarter of 2026.

Piper Sandler & Co. is serving as financial advisor and Luse Gorman, PC is serving as legal advisor to Esquire. Raymond James & Associates, Inc. is serving as financial advisor to Signature and Vedder Price P.C. is serving as legal advisor to Signature.

Customer spotlight: Reimagining what’s possible in commercial real estate financing

Across Chicago, Milwaukee and communities throughout the Midwest, vacant commercial buildings tell two stories: one of shifting markets – and one of opportunity. Former gyms, restaurants and big-box stores sit empty, waiting for the right vision to give them new purpose.

Successful redevelopment requires more than capital. It requires a commercial real estate partner who understands entrepreneurial decision-making, complex approvals and nontraditional financing structures.

“Signature Bank’s Commercial Real Estate team partners with business owners and investors who are reimagining underutilized spaces for new uses that serve surrounding communities,” said Kevin Bastuga, Co-Founder and Executive Vice President of Signature Bank. “We also work with clients developing new projects from the ground up or refinancing existing properties – staying engaged from concept through completion.”

Led by Steven Vernon III, SVP and Group Head of Commercial Real Estate, the team brings both discipline and creativity to projects that demand thoughtful execution.

Banking built for entrepreneurs, by entrepreneurs

Founded by entrepreneurs in 2006, Signature Bank brings an entrepreneurial mindset to commercial real estate lending. Rather than viewing unconventional projects as obstacles, our team approaches them as calculated opportunities – when supported by clear vision, planning and partnership.

Many of today’s most compelling developments involve repositioning properties that no longer fit their original purpose. These projects often require flexibility, trust and early involvement from a lender.

“The thing about real estate is that there’s always risk,” Vernon noted. “You have to believe in the property, believe in the borrower, and believe they can execute on their vision.”

That belief – grounded in careful underwriting and deep experience – has helped support projects that reshape neighborhoods and create lasting impact.

Life-saving care restores vitality to a vacant fitness building

One recent example is the transformation of a vacant LA Fitness building in Naperville, IL, into a modern surgery center and outpatient medical office.

Rather than leaving a large empty building unused, Capital Healthcare Properties and HSG Medical saw potential. Their vision required more than cosmetic updates – it involved a full reimagining of the property, navigating approvals and aligning the project with a clear community healthcare need.

Signature Bank partnered with the development team early, structuring financing that aligned with the project’s complexity and timeline. The result is a healthcare facility that will deliver critical outpatient services while revitalizing a formerly dormant site.

Projects like this aren’t simple. Medical facilities introduce additional layers of complexity in planning, construction and regulatory approvals. But the right banking partner can play an essential role in helping investors move complex projects forward.

“Redevelopment projects of this nature are inherently entrepreneurial,” noted Vernon. “When successful, the outcome can change the landscape in positive and lasting ways, particularly when they serve a broader community need.”

Daniel Ahlering, managing partner for Capital Healthcare Properties, credits Signature Bank with embracing their long-term vision.

“We entered one of the toughest and most volatile commercial real estate markets since the 2008 financial crisis,” said Ahlering. “At a time when most banks were hesitant to onboard new client relationships, Signature Bank recognized our track record and believed in our vision. They didn’t just understand our potential; they actively partnered with us by financing our first three projects.”

Turning a closed brewery into a new entertainment destination

In Chicago’s River North neighborhood, another vacant property is being repositioned – this time as an experiential entertainment destination.

The former Rock Bottom Brewery, which shut down in January 2023, is set to reopen in summer 2026 as an F1 Arcade – a dining and racing simulator concept inspired by Formula 1. The project transforms an empty restaurant into a high-energy destination that blends food, technology and entertainment.

Signature Bank provided financing to support redevelopment of the prominent location, helping ownership move quickly in a competitive urban market. The project reflects a broader shift in retail and dining toward experience-driven concepts – and the importance of working with a lender who understands how these evolving business models perform in real-world markets.

Vernon notes that many retail and restaurant projects today succeed by creating memorable experiences versus simply filling vacant square footage.

A different kind of partnership 

These redevelopment examples share a common thread: long-term partnership.

Signature Bank’s Commercial Real Estate team prioritizes direct communication, responsiveness and access to decision-makers. Projects are evaluated individually – considering the borrower, the real estate investment strategy and how the project ultimately serves the surrounding community.

That relationship-based approach is especially valuable in today’s environment, where repositioning and adaptive reuse play an increasingly important role in commercial real estate strategy.

“When you have the right partner, you can reimagine what a space can be,” Vernon said. “And when that happens, you’re not just filling vacancies, you’re creating something that lasts.”

Bringing ideas and spaces to life in creative ways 

From healthcare facilities to experiential retail, Signature Bank supports business owners and real estate investors across asset types and markets. The common thread is a shared ability to see opportunity in underutilized properties – and a disciplined path to bringing those visions to life.

“We’ve worked with Signature Bank for over 15 years, and they’ve been true partners every step of the way,” said Kage Brown, chief investment officer and managing partner, Hubbard Street Group. “Steve Vernon and Kevin Bastuga have consistently delivered, providing thoughtful guidance, competitive lending terms and efficient closings. Their team understands our business and has been instrumental in our continued growth.”

“For 20 years, Signature Bank has supported entrepreneurs who see possibility where others see risk,” said Bastuga. “That mindset continues to guide how we approach commercial real estate – with clarity, creativity and long-term commitment.”

Founder reflections: A 20-year journey in relationship banking

When Signature Bank opened its doors in August 2006, three entrepreneurs set out with a clear and somewhat unconventional vision: build a commercial bank rooted in relationships – not transactions.

Mick O’Rourke, Kevin Bastuga and Bryan Duncan were seasoned commercial bankers, but they were entrepreneurs at heart. They raised capital, wrote a business plan and left established institutions to create something they believed was missing in the market – a bank built for entrepreneurs, by entrepreneurs.

Twenty years later, that conviction still defines Signature Bank.

Through economic expansion, recession, a global pandemic and industry-wide liquidity turbulence, the bank has remained grounded in the same belief: long-term success is built on trust – and trust is built through relationships.

Relationships with a capital “R”

From the beginning, the founders envisioned something different.

They saw privately held companies and multi-generational family businesses searching for banking partners who understood not just their balance sheets, but their stories. They believed business owners preferred to work with people who had taken risks themselves – who understood payroll pressure, succession planning and the weight of long-term decision-making.

That entrepreneurial empathy became the cornerstone of the bank’s model.

“Business owners appreciate when their partners understand their world,” said Kevin Bastuga. “We launched our own business. We’ve built payroll. We understand the pressures. That perspective impacts how you relate to clients.”

Relationship banking at Signature Bank has never meant proximity alone. It means access to decision-makers. It means listening before advising. It means evaluating opportunities individually rather than through rigid formulas. It means staying present – especially when circumstances become difficult.

That philosophy has been tested repeatedly.

During the Great Recession, the founders ensured that Signature Bank maintained disciplined underwriting while continuing to support qualified borrowers. During the COVID-19 pandemic, teams worked around the clock to ensure clients secured Paycheck Protection Program loans quickly and accurately. In 2023, when an unrelated institution with a similar name failed, Mick, Kevin and Bryan hit the phones – proactively calling clients to reassure them, provide clarity and affirm they were available for questions any time, day or night.

In each case, the result was the same: relationships endured because they had been built deliberately over time.

“When people think of the term relationship, they think about a relationship with a small r. When we use the word relationship, it’s relationship with a capital R,” said Mick.

For Signature Bank’s founders, that distinction matters. A small “r” relationship may be transactional. A capital “R” relationship is built on consistency and accountability over time.

Relationships inside the bank

The founders’ vision for relationship banking was never limited to clients. From the beginning, Mick, Kevin and Bryan understood that the strength of the bank externally would depend on the strength of relationships internally.

They set the tone early: leadership would be accessible; titles would not create distance. No job would be beneath anyone. Accountability would be shared. If the bank was built on trust, that trust had to exist inside its walls first.

Over time, that example shaped the culture.

When employees describe Signature Bank, one word surfaces consistently: family. It reflects a workplace where colleagues rely on one another, where leaders remain visible and approachable, and where success is collective.

For those who have been part of the bank since its earliest days, the 20-year milestone carries deep meaning. “This anniversary means everything to me. I’m honestly proud every single day,” commented one employee.

That pride is rooted in shared experiences – each year, over the years: the 2006 grand opening, annual holiday parties that welcome employees’ spouses and children, music festivals and boat excursions, and 5-10-15 milestone celebrations marking growth (not just in assets but in people). There’s the comedy of traditional annual white elephant exchanges, and reflective memories of the intense, around-the-clock effort during the pandemic when teams rallied to ensure clients received the support they needed. 

These moments are not incidental; they reinforce the culture.

Modern capabilities, enduring values

Over the past 20 years, commercial banking has changed dramatically and Mick, Kevin and Bryan ensured that Signature Bank evolved alongside it.

From the beginning, the founders understood that strong relationships naturally expand over time. As clients grew, so did the complexity of their financial lives. Business owners were no longer seeking support solely for deposits and loans. They needed guidance around investment strategy, multi-generational wealth transfer, estate planning and fiduciary oversight.

Rather than refer those needs elsewhere, Signature Bank chose to deepen the relationship.

The bank expanded its Wealth Management offerings, strengthening its investment advisory capabilities and building a team focused on aligning financial strategies with clients’ broader personal and business goals. More recently, Signature launched Signature Trust Company, developed in partnership with Midwest Trust, bringing professional fiduciary and estate planning services into the bank’s relationship network.

“Our clients look to us for more than day-to-day banking. We’re here to serve that full financial picture for business and family operations,” said Bryan Duncan. “Expanding service lines was a natural extension of elevating our clients’ experiences.”

These expanded capabilities reflect – and strengthen – the bank’s relationship model.

Modernization has extended beyond advisory services. Digital platforms, real-time payments, enhanced treasury tools and layered fraud protection are now expected in commercial banking, and Signature Bank has invested continuously in modernizing its digital and treasury capabilities to meet those expectations.

Yet technology has never been viewed as a replacement for relationships. It is an enabler.

Integrated systems reduce administrative burden so bankers can spend more time advising, anticipating needs and identifying risk. Modern tools create efficiency, but accessible leadership and direct communication preserve connection.

As Signature Bank evolved – from services to technology – the founders made sure that one principle remained constant: modernization should always enrich the client experience, not diminish it.

Looking ahead: The next 20 years

For Mick, Kevin and Bryan, 20 years is a major milestone – and also a beginning.

“We wrote a business plan in 2005, and we’ve stayed remarkably consistent with it,” said Kevin Bastuga. “When you know who you are and who you serve, you don’t need to chase every trend. You just keep strengthening the relationships.”

The same mindset that led three bankers to leave secure careers and open a bank in 2006 still drives the organization forward. It is grounded in calculated risk, long-term thinking and personal accountability.

By remaining committed to relationship banking, Signature Bank is positioned to consistently grow and excel in its service offerings, even as the industry evolves around it.

“We built this bank on relationships grounded in trust, on capabilities that evolve with purpose, and on leadership that remains accessible,” said Mick O’Rourke. “That was our vision in 2006. It’s still our vision today – and it’s what will guide us for the next 20 years.”

Customer Spotlight: Beyond the Numbers – How a multi-generational family business found a true banking partner for growth 

Benz Metal Products has always prioritized relationships and connections over transactions. It’s the foundation of their business.

The Menomonee Falls, Wisconsin, metal fabrication company, now led by third-generation owners Jake, Joe and Jason van der Kooy, has built its reputation on trust and long-term partnerships. Every team member plays a role in building and maintaining customer relationships.

Over the past 50 years, the family-owned business has grown largely through referrals rather than traditional sales efforts. That relationship-first mindset shapes every part of the business, including the partners they choose, who are flexible and willing to adapt and grow with them. 

That includes Signature Bank.

Seeing more than the numbers

For much of its history, Benz Metal viewed banking primarily as a transactional necessity. The company had changed banks only twice in over 50 years. 

When Benz Metal ultimately switched to Signature Bank, they were struck by our approach. Rather than leading with spreadsheets and formulas, our team focused on learning the business. We asked about customers, growth plans, operations and leadership. We took time to understand how decisions are made and why.

Benz Metal said it was the first time a bank had looked beyond metrics and invested in the bigger picture. That approach aligned with how they do business.

“Signature Bank was the first bank that saw our whole story, more than just black and white numbers,” said Jake van der Kooy, CEO of Benz Metal. “Signature Bank invested in our family business, trusting how we operate. That’s an incredibly innovative approach.”

That understanding and trust didn’t begin in a boardroom. It started as a casual friendship formed between Jake and a Signature Bank banker while watching their sons play football.

From community connection to partnership

“What began as a personal connection became a business relationship,” said Brad Kranich, Senior Vice President and Division Head, Signature Bank in Wisconsin. “Over time, conversations shifted from football and family to their business and its direction.”  

There was no sales pitch and no pressure, just straightforward conversations and a clearer understanding of Benz Metal’s business. 

By the time Benz Metal was ready to explore financing for new equipment and facility expansion, the relationship with Signature Bank was already in place. Discussions felt collaborative, not transactional. And decisions were straightforward, guided by mutual understanding rather than rigid processes.

When trust removes friction

Benz Metal said one of the most meaningful outcomes of the partnership has been the ease of working with Signature Bank. Instead of navigating layers of emails and approvals, conversations are direct. Questions are handled quickly. And the focus stays on the business.

That efficiency matters. It allows the Benz Metal team to focus on running operations, supporting customers and planning for growth rather than getting caught in administrative back-and-forth. It also reflects trust.

Benz Metal has control over its decisions, whether that means investing in equipment, upgrading technology or responding quickly to customer needs. The team knows what’s best for the business, without having to justify every move or navigate unnecessary hurdles.

That assurance is especially meaningful for a third-generation, family-owned company. Benz Metal is focused on building for the long term and growing in ways that support the future of the business.

“By taking the time to understand how the family operates and how decisions are made, we pride ourselves on being a true partner, not just another lender or service provider,” said Mick O’Rourke, President & CEO of Signature Bank. “We’re a trusted supporter of the business and the people behind it.”

Building what comes next

As Benz Metal continues to grow and evolve, the company remains focused on what has always mattered most: relationships, quality and long-term thinking.

With Signature Bank alongside them, Benz Metal is positioned to continue growing while staying true to how the business has always operated. Because when a bank looks beyond the numbers, it can help a business build what comes next.

Let’s start the conversation

When a bank understands the story behind your business, better opportunities follow. If you’re exploring your next phase of growth, connect with Signature Bank to start a conversation about how relationship banking can support your plans. Contact us to get started.

What does modern banking look like? Personal relationships, powered by innovation.

Businesses manage money differently than they did a decade ago. As operations have evolved, so have expectations. Faster payments, real-time cash visibility and stronger fraud protection are no longer optional; they are essential to staying competitive and secure.

Yet modern banking isn’t defined by technology alone. It’s defined by how technology enables stronger client relationships.

At Signature Bank, we view digital innovation as the foundation that makes personalized commercial banking stronger. When systems integrate seamlessly and data flows in real time, our teams spend less time on manual processes and more time advising clients, identifying risk and uncovering opportunity.

That philosophy guides our continued investments in digital banking and treasury capabilities, ensuring innovation enhances the high-touch service our clients rely on.

So what does modern banking — with a personal touch — really look like? It’s trusted relationships backed by the right tools, real-time insight and experienced guidance that empower business leaders to make confident financial decisions.

Banking built for how businesses actually operate 

Treasury management has shifted from a back-office function to a strategic driver of operational efficiency, forecasting and enterprise risk management.

Businesses today should expect more than transaction processing. They should expect:

  • Seamless integration with ERP and accounting systems
  • Automated payment workflows that reduce manual effort
  • Real-time reporting and cash visibility
  • Strong internal controls and layered fraud protection
  • A treasury team that adds true value through discovery — not just implementation

Our process begins by understanding how a business actually operates. We roll up our sleeves, evaluate workflows, identify inefficiencies and uncover potential risks — then design solutions that fit into a client’s systems. 

That often includes helping businesses transition from paper-based payments to automated environments using ACH, virtual card payments and integrated payables platforms. Automation reduces manual steps, lowers the risk of error and fraud, and frees internal teams to focus on strategic priorities that improve cash flow and long-term performance.

Technology delivered with a personal touch

Delivering advanced tools is only the starting point. What sets us apart is how we implement and support them.

“Upgrading our digital banking platform was about more than adding new features — it was about making life easier and safer for our clients,” said Penny Foust, CTP, senior vice president of Treasury Management at Signature Bank. “Efficiency, security and insights are critical, but they only matter if businesses know how to put them to work. That’s where our team comes in. We don’t just hand over technology; we walk side by side with our clients to make sure these tools help their businesses run stronger every day.”

That hands-on philosophy shapes how we engage with clients. We work closely with controllers, CFOs and business leaders across industries — from manufacturing to professional services — to understand their processes, challenges and growth goals before recommending solutions. In many cases, that means rethinking workflows from the ground up and serving as an extension of a client’s internal team.

“Technology has changed everything about banking, from paper-based processes to real-time data and automation. But what hasn’t changed is that it’s still a people business. Technology only creates value when it’s paired with relationships, trust and a deep understanding of how our clients truly operate,” said Foust.

Innovation with security at the core

As digital capabilities expand, so does the fraud landscape. Real-time payments, APIs and system integrations introduce new efficiencies but also increase the importance of strong controls and informed oversight.  

It’s an unfortunate reality: the majority of businesses experience payment fraud in some form. Companies often have just one business day to identify and report unauthorized transactions before they become unrecoverable. Artificial intelligence has also introduced new threats, including digital impersonation and voice replication schemes.

That’s why we view security and fraud controls as integral to innovation, not add-ons or afterthoughts. Signature Bank’s digital and treasury solutions are designed with security embedded from the start, including:

  • Multi-factor authentication and layered access controls
  • Real-time monitoring and proactive alerts
  • Positive pay and advanced payment verification tools
  • Internal fraud mitigation controls
  • Ongoing education around emerging cybersecurity risks

Technology can flag potential risk, but it’s the people behind it who help prevent problems and keep business moving. Even the most advanced fraud detection tools require experienced oversight. When something appears unusual, our clients don’t navigate automated responses alone. They hear directly from someone who understands their business and can step in quickly to assess and respond.

Personalized banking, powered by agility

While many banks offer digital platforms, fewer offer true partnership.

“At Signature Bank, our technology exists to support banker-client relationships,” said Bryan Duncan, Co-Founder and Executive Vice President. “Our treasury, operations, IT and lending teams collaborate closely to ensure digital tools, fraud protections and financing strategies align with our client’s broader goals.”

Signature Bank operates with a team-based approach, which means that clients benefit from continuity and direct access to decision-makers. In an industry where banker turnover can disrupt service, our structure prioritizes long-term relationships and shared institutional knowledge.

That alignment also allows us to move quickly. Without unnecessary layers of bureaucracy, we can refine workflows, customize reporting and deploy enhancements efficiently. Clients don’t navigate red tape — they work directly with professionals who understand their business and can act decisively.

“We will continue investing in digital tools that strengthen efficiency and protection,” added Duncan. “And we will pair those tools with experienced professionals who listen, advise and stand beside our clients as their businesses grow.”

Andrea Brockland, Assistant Vice President, Assistant Retail Manager of Retail Banking at Signature Bank, greets client John Wrenn of Lakefront Hospitality Group.

Twenty years of evolving – and listening

As we celebrate 20 years of serving our clients, we recognize how dramatically commercial banking has changed. Processes that once relied on paper and manual approvals now operate in real time, connected through secure digital ecosystems.

But one principle has remained constant: strong banking relationships are built on trust, insight and accessibility.

“We aren’t just deploying technology,” Foust said. “We’re building financial ecosystems that are dynamic, secure and deeply relationship-driven.  That combination — innovation and high-touch service — is what modern banking should look like because it’s in the best interest of our customers.”

Let’s start the conversation

If you’re evaluating whether your current banking relationship delivers the integration, automation and fraud protection your business needs — along with the personalized guidance you deserve — we invite you to start the conversation.

Strengthening ACH fraud detection: What businesses need to know about Nacha’s 2026 rule changes

ACH (Automated Clearing House) payments are a vital part of how businesses pay employees, vendors and partners. As usage has grown, so have fraud attempts targeting ACH transactions – especially scams like business email compromise (BEC), vendor impersonation and payroll redirection.

To address these risks, Nacha announced new Risk Management Rules effective March 20th, 2026. These changes are designed to reduce ACH fraud, improve visibility into payment activity and strengthen the industry’s ability to recover funds when fraud occurs.

Below is an overview of what’s changing and what your business can do to prepare.

Why Nacha is updating the rules

The new rules reflect Nacha’s broader effort to:

  • Combat evolving fraud schemes – especially scams where fraudsters trick businesses or employees into sending legitimate ACH payments under false information.
  • Improve transparency across the ACH network – so that financial institutions can easily identify, flag and respond to suspicious activity.
  • Enhance fund recovery efforts – by making it easier to trace and react quickly when fraudulent transactions occur.

In short, these changes are about making the ACH network safer and more resilient for everyone who sends or receives payments.

Key changes businesses should understand

1. New fraud monitoring requirements
Nacha is requiring ACH participants to implement risk-based monitoring to better detect and prevent fraudulent ACH activity.

For businesses, this means your financial institution and service providers will be expected to:

  • Monitor payment patterns and behaviors for unusual or high-risk activity
  • Use tools and controls that help identify potential fraud
  • Respond quickly when suspicious transactions appear

While much of the technical monitoring occurs at the bank or processor level, businesses play an important role by reviewing their own ACH activity and using available fraud-prevention tools.

2. Who’s affected and when
The new requirements will be rolled out in two phases:

  • Phase 1 – March 20, 2026
    • Applies to high-volume Originators, ODFIs (Originating Depository Financial Institutions) and RDFIs (Receiving Depository Financial Institutions).
  • Phase 2 – June 19, 2026
    • Extends to all remaining participants in the ACH network.

If your business originates a significant volume of ACH payments, you may be impacted sooner, particularly through your bank’s enhanced monitoring and risk controls.

3. New definition of “False Pretenses”
Nacha is introducing a clearer definition of “False Pretenses” to directly address fraud that occurs when payments are initiated based on deceptive information rather than unauthorized account access.

This includes scams such as:

  • Vendor impersonation – A fraudster pretends to be a known supplier and asks you to change bank details.
  • Business email compromise (BEC) – Criminals gain access to or spoof a company email account and send convincing payment instructions.
  • Payroll redirection schemes – An attacker poses as an employee and requests changes to direct deposit information.

By defining “False Pretenses,” Nacha is recognizing that not all fraud involves a “hacked” account – often, the payment itself is “authorized” but based on false information. The new rules aim to support better prevention and stronger pathways for dispute and recovery.

4. Standardized entry descriptions: PAYROLL and PURCHASE
To improve clarity and make it easier to monitor transactions, Nacha will require standardized descriptions for certain ACH entries:

  • PAYROLL – Used for payroll-related payments, such as employee direct deposits.
  • PURCHASE – Used for purchase-related payments, such as vendor or supplier payments.

These standard entry descriptions help:

  • Enhance transparency into the purpose of each payment
  • Improve monitoring and analytics for fraud detection
  • Support faster identification of unusual or out-of-pattern transactions

For businesses, this may mean working with your bank or payroll/ERP provider to ensure the correct use of these descriptions in your ACH files.

What your business can do now

1. Review your current ACH processes

  • Evaluate how ACH payments are originated, approved and reconciled.
  • Identify any gaps where a fraudulent payment request could slip through—for example, a single person who can both set up and approve new vendors.

2. Strengthen internal controls

  • Require dual approval for new vendors, changes to vendor bank details and high-dollar payments.
  • Implement callback or out-of-band verification for changes to payment instructions.
  • Ensure payroll, AP and finance teams are trained to recognize red flags like urgent or secretive requests.

3. Coordinate across teams
Compliance, finance, operations and IT should work together to:

  • Align internal procedures with the upcoming Nacha standards
  • Document and regularly test fraud-prevention controls
  • Confirm that vendor management and payroll processes include verification steps for bank account changes

4. Engage early with your bank and providers

  • Discuss how your bank, ERP, payroll provider or AP automation platform will support the new Nacha rules.
  • Confirm that your systems will be ready for any file-format or description changes (such as PAYROLL and PURCHASE).
  • Ask about available monitoring tools, alerts and reporting to help you detect unusual ACH activity.

How Signature Bank can help
At Signature Bank, protecting your business from payments fraud is a core priority. Our solutions are built to help you meet evolving Nacha requirements while keeping your operations efficient and secure.

Key tools and capabilities include:

  • Positive Pay – Adds a critical layer of protection to help detect unauthorized or altered checks and or ACH debits before funds are released.
  • ACH monitoring & controls – Supports risk-based review of ACH activity, including filters, blocks and alerts tailored to your business.
  • Finrails® Technology – Integrates AP automation with bank-backed controls, giving you greater visibility, audit trails and security around your payments.

  • Review your current ACH setup and controls
  • Help you understand how Nacha’s 2026 changes apply to your organization
  • Recommend practical steps to reduce fraud risk and improve compliance

Is your business prepared for the fraud you don’t see coming?

Nearly 8 in 10 organizations were targeted by payment fraud last year – and most didn’t recover their losses.

For many business owners, payment fraud still feels like something that happens to someone else. Until it happens to you.

The truth is, fraud isn’t just growing – it’s getting smarter. Sophisticated tactics like altered checks, fake vendor ACH debits and business email compromise are costing businesses time, money, process disruption and potential reputational damage. And while larger companies often have robust fraud teams, smaller and mid-sized businesses are increasingly being targeted because criminals know they may lack strong controls.

At Signature Bank, we believe every business deserves the tools to defend itself – and that starts with Positive Pay Fraud Protection.

What is Positive Pay?
Positive Pay is a low-cost, automated fraud detection service that screens incoming payments – both checks and ACH – against a list of what your company has authorized. If a payment doesn’t match the details you’ve provided (think: wrong amount, wrong vendor, wrong check number), you get an alert and decide whether to approve or reject it.

Think of it as your early warning system – one that works around the clock and doesn’t let fraud slip through unnoticed.

So why aren’t more businesses using it?
It’s a question we hear often, even from our own clients. Many businesses assume their current accounting software or manual review process is “good enough.” Some have never experienced fraud and don’t see the urgency. Others are simply unsure of the setup process or assume it will be time-consuming and cost prohibited.

Here’s the reality: Only 22% of organizations that were victims of payment fraud in 2024 were able to recover 75% or more of their losses. That means for most, once the money’s gone – it’s gone.

Signature Bank makes it easy
We’ve made it our mission to take the friction frustration out of fraud protection. Signature Bank’s Treasury Management team works directly with clients to implement Positive Pay quickly and painlessly. We help you define the right rules, configure alerts, and ensure your files are being submitted securely and accurately.

What sets us apart is our hands-on approach.
You’re not expected to handle fraud detection alone. Our bankers monitor suspicious activity with you – and when something doesn’t look right, you’re not just getting an automated email. You’re getting a partner.

Whether you prefer to submit check files online or transmit them securely via SFTP, we’ve got the flexibility to meet your workflow.

Three ways Positive Pay protects you

  • ACH Positive Pay
    Create rules for vendors, transaction types and dollar limits. We flag or block anything outside your parameters and alert you when action is needed.
  • Check Positive Pay
    Prevent altered, forged, or duplicate checks by matching payee, amount, and check number against your issued file.
  • Reverse Positive Pay
    Want more control? We’ll send you a list of cleared checks for review – so you can approve or reject based on your own thresholds.

Don’t wait for fraud to happen
Positive Pay isn’t just a defense mechanism. It’s peace of mind. It’s control. It’s knowing that you have someone in your corner when the stakes are high.

If your business isn’t using Positive Pay yet, now is the time to act. Fraud is no longer a someday problem – it’s here. And it’s growing.
