Goldman Sachs Group Inc offered new tidbits about its sweeping operational overhaul when reporting first-quarter results on Monday, but investors focused on revenue declines across nearly all its main businesses, sending shares lower.

The bank’s profit fell 20 per cent to $2.2 billion, or $5.71 per share, from $2.7 billion, or $6.95 per share, in the year-ago period.

Analysts had expected a profit of $4.89 per share, according to IBES data from Refinitiv.

A main driver of the profit beat was a sharp drop in compensation costs, which helped cut operating expenses by11 per cent.

Total revenue of $8.81 billion missed Wall Street’s $8.99 billion estimate. The biggest drop came from Goldman’s trading business, which was hurt by lower market volatility and the impact of the US government shutdown.

Rivals JPMorgan Chase & Co and Citigroup Inc reported declines in trading revenue of 10 per cent and 6 per cent, respectively.

One bright spot was Goldman’s financial advisory business, where revenue soared 51 per cent on higher deal volumes. But the backlog of deals declined, indicating that revenue in future quarters may be subdued.

Goldman, the fifth-largest US bank by assets, was once considered a black box of profits, disclosing little about management’s goals or how its core units functioned. Investors and analysts generally accepted that secrecy, since Goldman routinely generated higher returns than peers.

But regulations imposed after the 2007-2009 financial crisis, combined with changing market trends, put some of its core businesses in peril. The bank embarked on a plan in 2017 to generate $5 billion in additional annual revenue, partly by diving into consumer banking, where it had never previously operated. It also promised to disclose more about its progress.

The bank has doubled down on that strategy under Chief Executive David Solomon, who started a “front-to-back” operational review after taking over as CEO in October.

Management is now putting in place the conclusions of that review, and plans to offer bank-wide performance targets early next year, Goldman said in an earnings presentation on Monday.

The bank also disclosed some narrower forecasts, along with “action items” to help grow profit.

But analysts said the bank is taking too long to turn around slumping businesses and set broad, operational goals.

It was also difficult to find evidence that the overhaul was bearing fruit in the first quarter. Declines in trading, underwriting, investment management and investing and lending all contributed to a 13 per cent slump in revenue, which missed Wall Street expectations.

“There’s a lot of work that needs to be done at this company to reposition it for growth over the next decade,” said David Hendler, an analyst at Viola Risk Advisors. “Not completing the strategic review until 2020 is ridiculous. It should be done by the next quarter.”
