9:38 a.m. ET: Caterpillar shares fall around market open as company warns of continued uncertainty

Dow-component Caterpillar (CAT) posted a fourth-quarter earnings beat, but its outlook disappointed as the company warned against future demand concerns stemming from an uncertain economic backdrop. Shares extended losses from early trading and opened about 2% lower.

Fourth-quarter adjusted earnings were $2.63 per share, topping estimates for $2.37. Caterpillar said this was driven by cost controls rather than an increase in sales volumes, with fourth-quarter revenue of $13.14 billion falling 8% over last year.

Caterpillar expects full-year 2020 earnings per share will be in a range of $8.50 to $10.00, or short of the $10.55 expected.

“We expect continued global economic uncertainty to pressure sales to users in 2020 and cause dealers to further reduce inventories,” CEO Jim Umpleby said in a statement.

The S&P 500 and Dow opened lower as fears over the coronavirus and some weak earnings results weighed on the indices.

9:05 a.m. ET: Exxon Mobil, Chevron shares fall after oil majors post mixed results

Exxon Mobil and Chevron posted mixed results for their fiscal fourth quarters, extending concerns for domestic players in the energy sector.

Exxon Mobil (XOM) delivered adjusted earnings per share of 41 cents, missing expectations by 2 cents for the quarter. This, however, excluded the positive impact of a one-time $3.7 billion gain from selling its assets in Norway as part of a broader divestment plan in Europe. Fourth-quarter revenue of $67.2 billion was well ahead of the $64.2 billion expected. Natural gas volumes were down 4% over last year, driven by declines in global gas prices as supplies rise. Overall production topped 4 million barrels a day of oil equivalent.

Chevron (CVX) posted fourth-quarter sales that missed estimates, while adjusted earnings per share of $1.49 were ahead of expectations by 4 cents. However, on an unadjusted basis, Chevron’s loss of $6.6 billion was the largest in a decade, driven by a $10.4 billion write-down of the value of its investments in natural gas fields in North America. Chevron’s production topped 3 million barrels a day of oil equivalent for the first time ever.

7:44 a.m. ET: British pound climbs with Brexit departure due today

It’s Brexit Day overseas, with the United Kingdom due to leave the European Union at 6 p.m. eastern time (11 p.m. GMT) on Friday, more than three-and-a-half years after the Brexit referendum.

Britain, a member of the EU since 1973, is poised to leave the bloc with 27 countries remaining. The UK and EU will enter a transition period through the end of 2020, allowing people and trade to flow between borders as usual, while British and EU negotiators try to come to a longer-term free trade deal by the end of the year.

The British pound climbed 0.2% to 1.18 against the euro (GBPEUR=X) and 0.3% to above 1.31 against the U.S. dollar (GBPUSD=X) Friday morning eastern time. The Bank of England’s monetary policy decision to hold interest rates unchanged on Thursday, when a cut had been expected by some, further supported the currency.
