NSTS Bancorp, Inc. (NSTS): ANSOFF MATRIX [Dec-2025 Updated]

You're looking at the growth blueprint for NSTS Bancorp, Inc. right when the rate environment is making every decision count; after all, even with improved performance in Q2 2025, the bank is still navigating a net loss, and that $5.0 million FHLB advance due in June 2025 demands a proactive stance. Forget vague corporate speak; this Ansoff Matrix cuts straight to the chase, mapping out four distinct paths-from aggressively capturing local deposits with a 1.5% APY offer to exploring entirely new revenue streams through diversification. It's a clear, actionable roadmap designed to move NSTS Bancorp beyond its current 5-county focus and secure solid footing. Here's the quick math: we need to decide which quadrant offers the best risk-adjusted return right now.

NSTS Bancorp, Inc. (NSTS) - Ansoff Matrix: Market Penetration

Increase cross-selling of existing deposit and loan products to current retail clients.

Offer a competitive 1.5% APY promotional rate on checking accounts to attract local competitors' deposits.

Launch a targeted digital marketing campaign within the current 5-county operating area.

Enhance the customer loyalty program to reduce annual customer churn below 8%.

Streamline the mortgage application process to cut approval time to under 48 hours.

NSTS Bancorp, Inc. reported Net interest income of $1,808 thousand for the three months ended June 30, 2025. The Net change in deposits for the six months ended June 30, 2025, was $8,998 thousand. As of December 31, 2024, the net loan portfolio totaled $130.4 million.

The organization's primary lending focus remains on one to four-family residential mortgage lending, which accounted for $119.4 million, or 91.2% of the total loan portfolio, as of December 31, 2024. The total assets reported as of December 31, 2022, were approximately $264 million.

Key financial metrics for recent periods include:

• Net change in deposits (6 months ended Jun 30, 2025): $8,998 thousand
• Net interest income (3 months ended Jun 30, 2025): $1,808 thousand
• Total Assets (Dec 31, 2022): $264 million
• Shares Outstanding (Mar 27, 2025): 5,247,826

The following table details selected balance sheet figures in thousands of USD as of June 30, 2025, compared to December 31, 2024:

Time deposits scheduled to mature in 2025 totaled $13,696 thousand. The weighted average shares outstanding for the nine months ended September 30, 2024, was 4,908,504.

NSTS Bancorp, Inc. (NSTS) - Ansoff Matrix: Market Development

The Market Development quadrant for NSTS Bancorp, Inc. centers on taking existing banking products and services into new geographical areas or new customer segments within a known service area.

The current operational footprint is concentrated, with a headquarters and main banking office in Waukegan, Illinois, alongside two additional full-service offices in Waukegan and Lindenhurst, Illinois. The total full-service physical presence is 3 locations. The lending activity already extends beyond the primary Lake County, Illinois market, actively originating residential home loans in the greater Chicagoland area, which includes loan production offices in Chicago, Aurora, and Plainfield, Illinois, and also in Kenosha County, Wisconsin.

The existing financial scale provides a baseline for expansion efforts. As of June 30, 2025, NSTS Bancorp, Inc. reported Total Assets of $275,976 thousand and Total Deposits of $190.2 million.

The existing commercial loan products, which include multi-family residential mortgage loans and commercial real estate loans, have shown no charge-offs for the years ended December 31, 2024, and 2023.

The Market Development strategies can be mapped against current operational realities:

• Expand physical branch presence into two adjacent, underserved metropolitan statistical areas (MSAs).
• Target the small-to-midsize business (SMB) segment in a new state with existing commercial loan products.
• Utilize digital-only banking to reach college students nationally with current savings accounts.
• Acquire a smaller, non-competing community bank to gain immediate access to a new region.
• Establish a dedicated team to serve high-net-worth individuals (HNWIs) in existing markets.

For the first point, the known adjacent lending area of Kenosha County, Wisconsin, suggests a logical first MSA target, complementing the existing loan production offices in the greater Chicagoland area (Cook County, Will County). The Green Bay Office is listed in Waukegan, IL, not Green Bay, WI, so physical expansion would target new MSAs beyond the current Waukegan/Lindenhurst/Chicago/Aurora/Plainfield footprint.

The digital-only strategy targets college students, a segment estimated at approximately 18.4 million in Spring 2025, with over 15 million being undergraduates. This segment could be reached using current savings accounts, which are offered alongside checking and money market accounts.

Regarding acquisitions, NSTS Bancorp, Inc. has stated that they currently have no agreements to acquire other financial institutions, though they may pursue this in the future.

The existing loan portfolio composition shows that non-1-4 family residential loans, which include commercial and multi-family, account for approximately 8.8% of the total loan portfolio ($130.4 million total loans minus $119.4 million in 1-4 family loans equals $11.0 million, or 8.4% of the total portfolio, with multi-family being $3.4 million). This existing base of commercial real estate and multi-family loans is the foundation for targeting the SMB segment.

NSTS Bancorp, Inc. (NSTS) - Ansoff Matrix: Product Development

You're looking to expand NSTS Bancorp, Inc.'s offerings into new product lines within its existing market, which means focusing on Product Development in the Ansoff Matrix. Given that your net loan portfolio totaled $130.4 million as of December 31, 2024, with 91.2% tied up in one- to four-family residential mortgages ($119.4 million), diversification is key. Your commercial real estate exposure was only $4.2 million, or 3.2% of that portfolio at year-end 2024.

Introduce a specialized green energy commercial loan product for local businesses.

This taps into a growing sector; in 2024, the U.S. deployed $338 billion in financing for energy technologies, and corporate procurement of renewable energy hit a record 28 gigawatts (GW). A specialized loan product could target businesses seeking to meet this energy transition demand. Consider that renewable energy's share of U.S. electricity grew to 24% in 2024.

Develop a proprietary mobile app feature for instant P2P payments and budgeting tools.

This addresses a clear digital preference. In the U.S., 70% of peer-to-peer (P2P) payments are already mobile-based. Furthermore, 71% of consumers in 2025 prefer banks to offer integrated P2P solutions for ease and security. You need to compete where the action is; about 81% of U.S. consumers used a P2P payment app at least once in 2025.

Launch a robo-advisory investment platform integrated with existing checking accounts.

This moves NSTS Bancorp, Inc. into wealth management technology. In the U.S. alone, robo-advisors are projected to manage $520 billion in assets by 2025. Hybrid models, which blend automation with human advice, captured about 45% of the market share in 2025. The average annual fee for these platforms hovers around 0.20% of Assets Under Management (AUM) in 2025.

Create a tiered certificate of deposit (CD) structure with a 6-month early withdrawal option.

This enhances your existing deposit products, where you hold time deposit accounts. The structure should be competitive against current market offerings. For example, you might structure tiers based on duration and penalty:

Offer a new home equity line of credit (HELOC) product with a fixed-rate conversion option.

This leverages the massive equity homeowners currently hold. U.S. homeowners hold nearly $36 trillion in tappable home equity, a record high. With mortgage rates still above 6% for many, homeowners prefer tapping equity via HELOCs rather than refinancing their primary loans. As of December 1, 2025, the average HELOC rate for strong profiles (780+ credit score, 70% CLTV) is 7.64%. A fixed-rate conversion option mitigates the risk of future prime rate increases, which is attractive when some lenders offer introductory rates under 5.99% for the first 12 months.

You have 53 employees to execute these new product rollouts. Your 2024 revenue was $8.93 million, showing an 82.49% increase year-over-year, though you reported losses of -$789,000. The zero dividend payout ratio in December 2024 suggests capital is being retained for growth initiatives like these.

• Green Energy Loan Target: Small to mid-sized commercial real estate clients.
• Mobile App Feature: Integrate budgeting tools with transaction categorization.
• Robo-Advisory: Target existing checking account holders aged 25 to 45.
• HELOC Conversion: Offer conversion at the prevailing fixed rate at the time of conversion request.

NSTS Bancorp, Inc. (NSTS) - Ansoff Matrix: Diversification

You're looking at growth beyond the core market of one- to four-family residential mortgage lending in Lake County, Illinois. Diversification here means moving into new products or new markets, which carries different risk profiles than simply selling more of what you already offer.

The current business, as of September 30, 2025, shows a loan portfolio, net of allowance, of $132,937 thousand, with net interest income for the three months ended June 30, 2025, at $1,808 thousand. This is the baseline for any new venture.

Here's a look at the scale of potential revenue streams from adjacent or new business lines, using data from larger, diversified peers in Q3 2025 to illustrate the magnitude of fee income possible:

The path forward involves specific, concrete actions to enter these new areas. You need to map out the investment required against the potential return for each.

Form a strategic partnership with a national FinTech firm for specialized lending in a new sector.

• This targets New Product/New Market diversification.
• The goal is fee generation from loan origination or servicing outside the current residential mortgage focus.
• A national partner could immediately provide access to markets where NSTS Bancorp, Inc. currently has zero footprint.

Establish a wholly-owned subsidiary offering property and casualty insurance in a new state.

• This is a classic New Product/New Market move.
• Requires capital allocation for licensing, staffing, and initial underwriting reserves.
• The subsidiary would operate under different regulatory oversight than the bank charter.

Acquire a regional wealth management firm to offer full-service brokerage outside the current footprint.

• This leverages an existing service type (wealth management is often adjacent to banking) into a New Market.
• The acquisition cost must be weighed against the potential for AUM (Assets Under Management) growth and recurring management fees.
• For instance, a firm managing $1.5 billion in AUM could generate significant fee income even at a low basis point charge.

Invest in a non-bank payment processing service to generate fee income from new markets.

• This is a pure New Product play, focusing on transaction-based revenue.
• The potential scale is suggested by peers like The Bancorp (TBBK), which saw payment fees reach $30.6 million in Q3 2025.
• This requires significant technology integration risk management.

Develop a specialized agricultural lending division targeting farmers in the Midwest.

• This is a New Market/New Product strategy, shifting credit risk concentration.
• It moves away from the current concentration where 91.2% of the loan portfolio as of December 31, 2024, was one to four-family residential mortgage loans.
• This requires building specialized underwriting expertise from the ground up.
