Credit Suisse produced another rise in net profit for the first quarter of 2019, its first reporting period following the completion of its three-year restructuring plan.

The bank reported a net income of 749 million Swiss francs ($733.93 million) for the first quarter of this year, an 8% increase year-on-year. Analyst expectations were pointing to a net income of 692 million Swiss francs, according to a Reuters poll.

Here are some of the key highlights of the first quarter:

Net revenue hit 5.4 billion Swiss francs, versus 4.8 billion in the fourth quarter of 2018.

Its CET 1 ratio stood at 12.6% in the first quarter, unchanged from the previous quarter.

Tidjane Thiam, chief executive officer of Credit Suisse, told CNBC Wednesday that it was a "good quarter overall, after a very slow and difficult start."

In an earnings statement, the bank said it was operating with a lower risk profile, a stronger capital base and a structurally lower cost base. Thiam reiterated that the bank's model is "resilient," which has allowed it to protect its "bottom line during periods when markets are challenging."

The performance in the first quarter was particularly driven by the bank's international wealth management unit, which delivered a net revenue of 1.4 billion Swiss francs. On the other hand, the investment banking arm reported lower revenues compared to the fourth quarter, with a total net revenue of 356 million Swiss francs.

Shares were up by more 3% in early deals.
