“Our record third quarter results reflect the strength of our diversified business model and disciplined execution across the company,” said NBT President and CEO Scott Kingsley. “We delivered solid loan growth, grew net interest income and expanded our net interest margin, and continued to maintain strong capital levels. These results position us well to continue serving our customers and communities and creating long-term value for our shareholders.”

Revenue growth

Two primary revenue streams drive bank earnings. While net interest income, which is earned by charging higher rates on loans than paid on deposits, forms the foundation, fee-based services across banking, credit, wealth management and trading operations provide additional income. NBT Bancorp’s revenue grew at a mediocre 9.8% compounded annual growth rate over the last five years, falling short of the banking sector standard.

Long-term growth matters the most, but within financials, a half-decade historical view may miss recent interest rate changes, market returns and industry trends. NBT Bancorp’s annualized revenue growth of 15.3% over the last two years is above its five-year trend, suggesting its demand recently accelerated. Note: Quarters not shown were determined to be outliers because they were impacted by outsized investment gains/losses that are not indicative of the recurring fundamentals of the business.

This quarter, NBT Bancorp reported modest year-on-year revenue growth of 4.5% but beat Wall Street’s consensus estimates by 0.6%.

Net interest income made up 70.4% of the company’s total revenue during the last five years, meaning lending operations are NBT Bancorp’s largest source of revenue.

Markets consistently prioritize net interest income growth over fee-based revenue, recognizing its superior quality and recurring nature compared to the more unpredictable non-interest income streams.

Tangible book value per share (TBVPS)

Banks are balance sheet-driven businesses because they generate earnings primarily through borrowing and lending. They’re also valued based on their balance sheet strength and ability to compound book value (another name for shareholders’ equity) over time.

This makes tangible book value per share (TBVPS) the most important metric to track for banks. TBVPS represents the real, liquid net worth per share of a bank, excluding intangible assets that have debatable value upon liquidation. Other (and more commonly known) per-share metrics like EPS can sometimes be murky due to M&A or accounting rules allowing for loan losses to be spread out.

NBT Bancorp’s TBVPS grew at a mediocre 4.8% annual rate over the last five years. However, growth accelerated to 7.9% annually over the last two years, with TBVPS rising from $23.83 to $27.75 per share.

Over the next 12 months, consensus estimates call for NBT Bancorp’s TBVPS to grow by 13.6% to $31.52, a decent growth rate.

Key takeaways from NBT Bancorp’s Q3 results

A tangible book value per share miss left NBT Bancorp with a quarter that could have been better. Revenue narrowly topped analysts’ consensus estimates and EPS came in slightly ahead of Wall Street’s consensus, but those positives did not erase the shortfall. Shares remained flat at $52.94 immediately after the results.
