Plumas Bancorp (PLBC) Q3 2026 earnings review
Plumas Bancorp profit hits a record, but loans stay flat
Plumas Bancorp, the parent of California and Nevada community lender Plumas Bank, reported record profit while its loan book stood still. Net income more than doubled from a year ago to $11 million, because last year's quarter carried $5 million in day-one loan reserves for the Cornerstone acquisition and this quarter gained $1.2 million from green energy tax credits. Chief executive Andrew J. Ryback said loan repricing supported profitability, lifting net interest income 5% to $27 million.
| Net interest income | $26.5M +5.4% from a year ago |
|---|---|
| Net interest margin | 5.05% +0.22 percentage points from a year ago |
| Diluted profit per share | $1.61 +121% from a year ago ($0.73) |
| Nonperforming loans | $21.1M -10% from last quarter ($23.5M) |
⚖️ Verdict: 🟢 Bullish
The story got better because problem loans started shrinking and five-year commercial property loan resets held the net interest margin above 5%. Nonperforming loans fell 10% from June's peak, allowing the bank to record a tiny $150 thousand credit provision. One caution: excluding the tax credit and last year's merger charges, profit rose 7% by our math, and unrealized bond losses cut tangible book value per share by 4% from June.
The question now is whether Plumas can grow its loan book and protect its 5.05% lending margin as interest rates fall. Either new commercial property and government-backed small business loans outpace the planned runoff of auto loans, or falling prime rates squeeze asset yields while loan balances stagnate. Fourth-quarter loan balances and net interest margin will tell.
🐂 Bull Case
Loan Repricing Lifted Lending Margins Over the Year
Plumas Bancorp, the parent of northern California and Nevada community lender Plumas Bank, passed the first anniversary of its July 2025 Cornerstone Community Bancorp purchase. Chief executive Andrew J. Ryback said the bank's low-cost deposits and higher loan yields supported profit, "with continued loan repricing helping to maintain strong net interest margin." Net interest margin is the percentage spread a bank earns between interest on loans and bonds and interest paid on deposits.
- Net interest margin: 5.05%, up 0.22 percentage points from a year ago
- Net interest income: $26.5 million, up 5.4% from a year ago
- Average loan yield: 6.56%, up 0.21 percentage points from a year ago
- Fixed-rate Small Business Administration (SBA) government-backed business loans: $132 million at an 8.0% average rate, up 40.4% from $94 million a year ago
This expansion matters because 79% of the loan book carries a variable interest rate, and 78% of those variable loans reset every five years against the five-year US Treasury bill rate. Older commercial property loans originated in lower-rate years are still resetting higher, while 46.1% of deposits pay zero interest, keeping total funding costs down at 0.86% of earning assets.
What to watch: average loan yield and time deposit rates in the fourth-quarter report. Continued five-year commercial real estate resets above 6.5% would keep net interest margin above 5% even as short-term benchmark rates fall.
Nonperforming Loans Fell From the Second-Quarter Peak
Problem loans have been a central focus since Plumas placed a single agricultural borrowing relationship on nonaccrual status in mid-2025. Nonperforming loans are loans that are past due or no longer accruing interest. "Asset quality slightly improved during the quarter, and we continue to work toward favorable resolutions with the same relationships," Ryback said. A $1.6 million delinquent loan that was still accruing interest in June paid off in full during July.
Nonperforming loans dropped 10.0% from last quarter to $21.1 million, or 1.41% of total loans, down from 1.55% at the end of June. Because problem loans decreased and net loan write-offs stayed low at $148 thousand for the quarter, the bank added only $150 thousand to its credit loss provision, down from $600 thousand in the second quarter. However, nonperforming loans remain 40.6% higher than the $15.0 million recorded a year ago.
What to watch: nonperforming loan balances and loan collection expenses in the fourth quarter. A drop below $15 million would show that the bank has resolved the remaining workouts acquired or flagged last year.
🐻 Bear Case
One-Time Items Drove Most of the Profit Jump
Plumas announced record third-quarter net income of $11.4 million, or $1.61 per diluted share, more than double the $5.1 million, or $0.73 per share, earned a year ago. While the headline growth rate is 121.3%, both periods included large one-time items that distort the comparison across the Cornerstone acquisition close.
- Third-quarter 2025 credit provision: $5.4 million, driven by a $5.0 million day-one accounting charge on acquired Cornerstone loans, versus $150 thousand this quarter
- Third-quarter 2025 merger and bond-sale items: $879 thousand in acquisition costs and a $628 thousand loss on selling investment securities, versus zero this quarter
- Third-quarter 2026 tax credit: bought $14.5 million in green energy tax credits, cutting income tax expense by $1.2 million and lowering the tax rate to 18.9% from 25.6%
Stripping out the $1.2 million tax credit benefit this quarter and comparing against last year's earnings excluding merger items, net income grew 7.1% to $10.2 million by our math. Pre-tax profit excluding last year's merger charges and bond losses and this quarter's $350 thousand in one-off legal and collection fees rose 4.6% by our math, showing modest underlying growth rather than a doubling of core earnings power.
What to watch: fourth-quarter pre-tax income before credit provisions and one-off tax credits. That figure will show whether underlying revenue growth can exceed the 4% to 5% pace without accounting tailwinds.
Lower Benchmark Rates and Auto RunoffCapped Loan Growth
While lending spreads improved from a year ago, net interest margin slipped 0.08 percentage points from the second quarter's 5.13% to 5.05%. The average prime interest rate fell to 6.79% from 7.46% a year ago, which immediately reduced yields on the 19% of variable-rate loans tied to prime and cut the yield earned on Federal Reserve cash balances by 0.74 percentage points to 3.69%.
At the same time, total gross loans stayed flat from a year ago at $1.50 billion and shrank by $16.6 million from the second quarter. Ryback pointed to the "continued planned runoff of our lower-yielding indirect auto portfolio" for the flat loan book. Auto loans fell 43.7% from a year ago to $25.4 million, and agricultural loans dropped 9.6% to $139.3 million, offsetting a $35.2 million increase in commercial real estate loans.
What to watch: net loan balances and the yield on earning assets next quarter. Further prime rate cuts will test whether commercial property and SBA loan originations can outpace auto and agricultural paydowns.
Bond Portfolio Losses Reduced Tangible Book Value
Plumas holds $475.2 million in government agency and municipal debt securities to support liquidity. Over the past year, unrealized losses on this bond portfolio nearly doubled from $23 million to $44 million. Because these bonds are classified as available for sale, the paper losses flow directly through shareholders' equity as accumulated other comprehensive loss, which widened by $14.8 million over the past twelve months to $31.3 million.
Those bond valuation marks caused total shareholders' equity to fall from $272.1 million in June to $262.5 million in September, even though the bank earned $11.4 million in the quarter. Tangible book value per share—net worth excluding goodwill and deposit intangibles—dropped 3.6% from last quarter to $32.95, though it remains up 9.1% from $30.21 a year ago.
What to watch: unrealized security losses and tangible book value per share at year-end. A narrower bond loss would allow retained earnings to flow straight into book value growth.

Lapped Merger Costs Lowered the Efficiency Ratio
Non-interest expense stayed flat from a year ago at $15.1 million, improving the efficiency ratio—operating costs as a share of total revenue—by 3.6 percentage points to 51.6%. Merger expenses fell by 3.2 percentage points of revenue as Cornerstone deal costs lapped, and salaries fell 1.0 point to 26.1% of revenue. Excluding last year's $879 thousand merger charge and $350 thousand of nonrecurring collection and professional fees this quarter, overhead rose 3.8% by our math.
💲 Other KPIs
Deposits rose 2.6% from a year ago, adding $47.1 million, but dipped 1.0% ($18.4 million) from the second quarter. Money market accounts grew $37.8 million from last year—helped by reclassifying $41 million of Cornerstone repurchase agreements—and time deposits rose $22.3 million, while non-interest-bearing accounts held at 46.1% of total deposits.
Plumas Bank's Common Equity Tier 1 capital ratio—core equity as a share of risk-weighted assets—rose 0.6 percentage points from the second quarter and 2.1 points from 14.3% a year ago after the Cornerstone close. The company also repurchased 80 thousand shares for $4.2 million over the past year, including about 20 thousand shares in the third quarter.
Combined customer repurchase agreements ($62.2 million) and bank borrowings ($16.0 million) fell 36.7% from $123.6 million a year ago by our math. The bank redeemed $10 million of assumed Cornerstone subordinated notes in late 2025, shifted $41 million of repurchase accounts into money market deposits, and ended the quarter with $576 million in unused borrowing lines.
❓ Key Questions
What is the timeline for resolving the agricultural nonaccrual loans?
Nonperforming loans fell by $2.3 million this quarter to $21.1 million, but loan collection expenses jumped 163% from a year ago to $287 thousand. Investors need to know how much of the remaining $21.1 million belongs to the 2025 agricultural workout and when collateral sales will close.
How much will the note payable reset add to interest expense?
Plumas holds a $14.3 million loan with a correspondent bank that carries a fixed 3.85% interest rate until January 25, 2027, when it switches to a floating rate tied to the Wall Street Journal Prime Rate. Will management prepay this loan using cash before the rate jumps?
Why did unrealized losses on the bond portfolio double in Q3?
Unrealized losses on available-for-sale investment securities grew from $23 million a year ago to $44 million at September 30, 2026, pulling tangible book value per share down 3.6% in a single quarter. Management has not explained which government agency or municipal holdings drove the mark-to-market drop.
How much remains under the $25 million share repurchase authorization?
The board authorized a $25 million stock buyback program in February 2026 running through the fourth quarter of 2026, and the company has spent $4.2 million over the past twelve months. Will the board extend the program into 2027 or accelerate purchases before year-end?
