It was an understatement to say that Wednesday was a busy and prosperous day for Middlefield Banc (MBCN +17.09%). The lender published its latest set of quarterly figures and announced it was merging with a peer. These happenings pushed its stock up by more than 17% on the day, contrasting very nicely with the S&P 500's (SNPINDEX: ^GSPC) 0.5% slump.
Banking on improvements
Middlefield, a regional banking and financial services company based in Ohio, took the wraps off its third-quarter and nine-month performance that morning.

The numbers were pleasing. Total revenue rose by 18% year over year to $19.9 million, while generally accepted accounting principles (GAAP) net income more than doubled from $2.3 million to $5.3 million ($0.65 per share).
As for key balance sheet items, Middlefield's total loans and deposits both grew by 7% over that one-year stretch. They also both came in just above $1.6 billion.
In the press release detailing the quarter's results, Middlefield attributed the improvements to "steady" asset growth and its ability to improve margins, thanks in no small part to effective operating expense discipline.
