Old Second (OSBC) Q1 2026 Earnings Transcript

Old Second Bancorp posted Q1 net income of $25.6 million, or $0.48 per share, with NIM expanding to 5.14% and tangible book value rising to $14.35 per share. Offsetting the strong margin and capital trends, net charge-offs were elevated at $9.8 million, nonperforming loans rose to $22.7 million, and management flagged ongoing stress in office CRE and powersports credit. The bank reiterated mid-single-digit loan growth and 3%-4% expense growth guidance while continuing aggressive buybacks, including 1.2 million shares repurchased at $19.63.

Analysis

OSBC’s key takeaway is not the quarter’s slight earnings beat; it is that the franchise is still generating enough spread income to self-fund buybacks while absorbing isolated credit slippage. That matters because the market usually prices regional banks as a balance-sheet story first and an earnings story second; here, the earnings engine is intact, so incremental downside is more likely to come from sentiment around office and specialty-lending losses than from core profitability. The stock should trade less like a generic bank and more like a levered compounder with episodic credit headline risk.

The second-order issue is that management is choosing to shrink the funding base and wind down low-quality participation exposure even though that creates a near-term growth headwind. That is constructive for long-duration franchise value: lower wholesale dependence, lower deposit beta, and more capital return capacity all improve resilience if rates stay sticky or drift higher. The tradeoff is that reported loan growth may undershoot headline guidance if the mix continues to migrate away from lower-quality balances, so investors looking only at top-line loans may misread the trajectory.

The most important contrarian point is that elevated charge-offs are not automatically bearish if the portfolio seasoning is improving and pricing power remains rational. The power sports book appears to be behaving like a high-yield specialty lender where the right metric is net contribution after losses, not gross charge-offs; if underwriting tightening and mix shift continue, the current loss print could actually mark peak pain. Office remains the real tail risk: not because of size, but because another mark-down or restructuring could compress the multiple even if earnings hold up, especially if broader CRE sentiment turns again over the next 1-2 quarters.

Key Decisions for Investors

• Long OSBC into weakness over the next 2-6 weeks if the stock sells off on charge-off headlines; risk/reward favors owning a bank that is still buying back stock, compounding TBV, and producing mid-teens ROTCE. Use a 5-8% downside stop if office NPA commentary worsens materially.
• Sell short-dated OSBC puts 5-10% below spot to monetize elevated credit-event premium; thesis is that near-term earnings power and buybacks should cushion the stock unless a new office impairment emerges.
• Pair trade: long OSBC / short a basket of regional banks with weaker NIM and higher deposit beta over 1-3 months. OSBC’s lower funding cost and capital return profile should outperform if rates remain stable and the curve does not re-steepen sharply.
• Avoid chasing higher-beta specialty lenders with worse credit transparency; OSBC’s specialty book is already being repriced by the market, but unlike weaker peers it still has capital flexibility to absorb losses and continue repurchases.
• If OSBC rallies back toward a premium-to-book valuation without evidence of NPA improvement, fade the move with a tactical short or call spread hedge for 1-2 quarters, since multiple expansion likely stalls until office and participation runoff are visibly behind them.
