Exxon quietly sells $169 million bond maturing in 2076, tailored to niche tax buyers

Exxon Mobil Corp. has quietly sold a small, highly engineered bond that will not mature until 2076, offering a glimpse into how one of the world’s largest oil companies is tapping niche corners of the debt market to raise money at extremely low cost.

In a Form 8-K filed March 31 with the Securities and Exchange Commission, Exxon said it entered an underwriting agreement on March 26 with RBC Capital Markets LLC, J.P. Morgan Securities LLC and UBS Securities LLC for the issuance and sale of $169.3 million in floating-rate notes due March 30, 2076.

“The Company entered into an underwriting agreement … for the issuance and sale by the Company of $169,312,000 aggregate principal amount of its Floating Rate Notes due 2076,” Exxon stated in the filing.

Small deal, highly customized terms

The securities are small by the standards of a company with a market value above $700 billion and long-term debt in the mid-$30 billion range. But their structure — a 50-year maturity, interest tied to the Secured Overnight Financing Rate (SOFR) at a discount, a web of call and put options, and language tailored to a specific tax provision — highlights how blue-chip issuers fine-tune offerings for specialized investor demand.

Under the prospectus supplement filed in connection with the deal, the notes pay a floating rate equal to compounded SOFR minus 0.45 percentage point per year. Interest is payable quarterly in arrears on March 30, June 30, September 30 and December 30, starting June 30, 2026.

The bonds were sold at 100% of face value, with underwriters receiving a 1% discount, leaving Exxon with estimated net proceeds of about $167 million.

“We estimate that the net proceeds to us from the sale of the Notes will be approximately $167 million,” the company said. “We intend to use the net proceeds from the sale of the Notes for general corporate purposes.”

The notes are senior, unsecured and unsubordinated obligations of Exxon and rank equally with its other unsecured, unsubordinated debt. They were issued under a shelf registration statement on Form S‑3 filed Feb. 18, 2026, giving the company latitude to bring multiple securities to market over time.

Call, put and a “tax event” maturity trigger

Beginning March 30, 2056, Exxon may redeem some or all of the notes at a premium to face value, starting at 105% of principal and stepping down annually until the redemption price reaches 100% on or after March 30, 2066, plus accrued interest.

Holders, for their part, can require Exxon to buy back some or all of their notes starting March 30, 2027, at specified prices and dates detailed in the prospectus. Early in the life of the bonds, many of those put dates come at 98% of principal, later rising toward par and extending through March 30, 2073.

The company also built in a “tax event” clause that allows it to shorten the maturity date if a change in U.S. tax law, regulation or official guidance creates more than an “insubstantial” risk that interest on the notes would not be tax-deductible. In that case, Exxon could advance the maturity and repay the notes at 100% of principal plus accrued interest.

A bond marketed around ESOP tax planning

The prospectus devotes unusual attention to another aspect: potential treatment of the notes as “qualified replacement property” under Section 1042 of the Internal Revenue Code.

That provision allows certain owners of closely held C corporations to defer capital gains tax when they sell stock to an employee stock ownership plan (ESOP) and reinvest the proceeds in qualifying securities of domestic operating companies. Long-term corporate bonds that meet specific tests can qualify.

Exxon tells investors it believes it meets the definition of a domestic operating corporation and that the notes “should constitute ‘qualified replacement property’ for purposes of Section 1042,” provided various conditions are met, including a Passive Income Test based on the company’s income mix.

At the same time, it cautions that the Internal Revenue Service is not bound by its determinations.

“The IRS could disagree with our determinations,” the company warns, adding that it “cannot assure you that the Notes will qualify as ‘qualified replacement property’ at the time of your purchase or throughout your holding period.”

That framing effectively markets the bonds to a narrow but lucrative group: owners of private companies who sell to ESOPs and need to reinvest large sale proceeds into qualifying securities to defer capital gains. Those investors often seek long-dated, highly rated, U.S.-dollar instruments, and they may be less sensitive to modestly below-market coupons if the security fits their tax strategy.

The deal extends a template Exxon has used before. In 2024, the company issued floating-rate notes due 2074 with a similar principal amount, the same reference rate of compounded SOFR minus 0.45 percentage point, comparable call and put features, and the same focus on Section 1042 treatment.

Balance sheet context and SOFR-era risks

For Exxon, the latest offering comes against the backdrop of a balance sheet the company routinely describes as strong. Analysts place the company’s total debt in the mid-$30 billion range and net debt — total debt minus cash and equivalents — at roughly $20 billion, alongside equity in the hundreds of billions. Ratings agencies have historically assigned the company high-grade, A-range ratings on its senior unsecured debt.

The modest size of the 2076 notes means they have little bearing on overall leverage. On March 31, when the 8-K was filed, Exxon’s stock closed modestly lower, but market commentary at the time linked the move primarily to shifting oil prices, not the bond sale.

The notes also situate Exxon firmly within the post-LIBOR shift to SOFR, the overnight rate based on transactions in the U.S. Treasury repurchase market that has become the main replacement benchmark for dollar markets. The prospectus underscores that the new standard carries its own uncertainties.

“The future performance of the Secured Overnight Financing Rate (‘SOFR’) cannot be predicted based on historical performance,” the company writes. “There can be no assurance that SOFR will be positive.”

Exxon says it does not intend to list the notes on any securities exchange. Underwriters may make a market in the bonds but are under no obligation to do so, leaving some risk that liquidity and pricing in secondary trading could be limited.

A 50-year bet beyond midcentury

The 2076 maturity date also stretches well beyond the company’s climate-related targets. Exxon has said it aims for net-zero greenhouse gas emissions from its operated assets’ Scope 1 and 2 emissions by 2050 and has pointed to growth businesses in carbon capture and storage, hydrogen, lower-emission fuels and lithium as part of its long-term strategy.

By issuing conventional senior debt that could remain outstanding until 2076, the company is signaling that it expects its business model — combining oil and gas with expanding lower-emission operations — to generate enough cash to meet obligations far past midcentury.

The filing itself is largely procedural. The March 31 Form 8-K uses Item 8.01, “Other Events,” to describe the transaction, and Item 9.01, “Financial Statements and Exhibits,” to attach the underwriting agreement, officer’s certificate setting the final terms, prior indentures, legal opinions and related consents. No new financial statements were included.

For investors and policymakers, the deal illustrates how a corporate giant uses the machinery of SEC registration, floating-rate benchmarks and the tax code to access a specific pool of capital on favorable terms. For Exxon, it is a small piece of its funding strategy. For buyers, it is both a long-term claim on one of the world’s largest energy companies and, in many cases, a key component of a broader tax and estate plan.

Unless the notes are called, repurchased or their maturity shortened along the way, the final payment date will fall exactly 50 years after the bonds were issued — long after today’s executives have left and decades beyond the company’s current emissions pledges. The willingness of investors to hold that risk, even at a rate below a benchmark overnight rate, reflects a bet not only on Exxon Mobil’s balance sheet, but on its place in the global energy system half a century from now.
