MTB Upgrade Ignores Funding Risk; Maintain WAIT

What happened

M&T Bank was upgraded from Hold to Buy by a Seeking Alpha analyst after Q3, which saw double-digit net interest income growth and top- and bottom-line beats, supported by rising fee-based revenue. That quarterly momentum lifted book value 5% year-over-year, placing the stock at 1.45x P/B, in line with peers. However, the upgrade is based on reported profitability rather than the bank's underlying funding mix, which was a key concern in the prior quarter when deposits declined and short-term borrowings spiked. Without new deposit and wholesale funding data, the upgrade may overstate the durability of earnings if the bank is relying on higher-cost borrowings. Consequently, the positive headline does not resolve the core question of whether NII can be sustained while the Fed eases, and the stock remains a WAIT until funding stability is confirmed.

Implication

The Q3 beat and Buy upgrade may initially attract buyers, but investors should scrutinize the deposit and wholesale funding trends before chasing the stock. The prior quarter showed a sharp rise in short-term borrowings and a slight decline in deposits, which could undermine NII if it persists. The upgrade does not provide evidence that this funding fragility has been resolved. A prudent approach is to wait for the next quarterly filing to confirm that NII growth is funded by stable, low-cost deposits. Only if deposit levels recover and borrowings normalize would the earnings momentum justify a more constructive stance.

Thesis delta

The upgrade to Buy reflects strong Q3 momentum, but it does not address the deposit outflow and wholesale funding reliance flagged in the prior quarter. We maintain a WAIT rating demanding evidence that NII growth is funded by sticky deposits rather than short-term borrowings. Without that, the earnings beat may not be repeatable.
