CROSS TIMBERS ROYALTY TRUST

PART I - FINANCIAL INFORMATION

Item 1.  Financial Statements.

The condensed financial statements included herein are presented, without audit, pursuant to the rules and regulations of the Securities and
Exchange Commission. Certain information and footnote disclosures normally included in annual financial statements have been condensed or omitted pursuant to such rules and regulations, although the Trustee believes that the disclosures are adequate
to make the information presented not misleading. These condensed financial statements should be read in conjunction with the financial statements and the notes thereto included in the Trusts latest Annual Report on Form 10-K. In the opinion of the Trustee, all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the assets, liabilities and trust corpus of the Cross Timbers Royalty Trust at
September 30, 2018, and the distributable income and changes in trust corpus for the three-month and nine-month periods ended September 30, 2018 and 2017, have been included. Distributable income for such interim periods is not necessarily
indicative of distributable income for the full year. The condensed financial statements as of September 30, 2018, and for the three-month and nine-month periods ended September 30, 2018 and 2017 have been subjected to a review by
PricewaterhouseCoopers LLP, the Trusts independent registered public accounting firm, whose report is included herein.

Report of Independent Registered Public Accounting Firm

To the Unitholders of Cross Timbers Royalty Trust and

Simmons Bank, Trustee:

Results of Review of Financial Statements

We have reviewed the accompanying condensed statement of assets, liabilities and trust corpus of Cross Timbers Royalty

Trust (the Trust) as of September 30, 2018, and the related condensed statements of distributable income and of changes

in trust corpus for the three-month and nine-month periods ended September 30, 2018 and 2017, including the related

notes (collectively referred to as the interim financial statements). Based on our reviews, we are not aware of any

material modifications that should be made to the accompanying interim financial statements for them to be in conformity

with the modified cash basis of accounting described in Note 1.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board

(United States), the statements of assets, liabilities and trust corpus as of December 31, 2017, and the related statements of

distributable income and of changes in trust corpus for the year then ended (not presented herein), and in our report dated

March 12, 2018, which included a paragraph describing the modified cash basis of accounting, we expressed an

unqualified opinion on those financial statements. In our opinion, the information set forth in the accompanying

condensed statement of assets, liabilities and trust corpus as of December 31, 2017, is fairly stated, in all material respects,

in relation to the statements of assets, liabilities and trust corpus from which it has been derived.

Basis for Review Results

These interim financial statements are the responsibility of the Trusts management. We are a public accounting firm

registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with
respect to the Trust in accordance with the U.S. federal securities laws and the applicable rules and

regulations of the Securities and
Exchange Commission and the PCAOB. We conducted our review in accordance with

the standards of the PCAOB. A review of interim financial
information consists principally of applying analytical

procedures and making inquiries of persons responsible for financial and
accounting matters. It is substantially less in

scope than an audit conducted in accordance with the standards of the PCAOB, the objective
of which is the expression of

an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an
opinion.

Basis of Accounting

As described in Note 1, these financial statements were prepared on the modified cash basis of accounting, which is a

comprehensive basis of accounting other than accounting principles generally accepted in the United States of America.

CROSS TIMBERS ROYALTY TRUST



Notes
to Condensed Financial Statements (Unaudited)



|1. | Basis of Accounting
|-- | -------------------

The financial statements of Cross Timbers Royalty Trust (the Trust) are prepared on the following basis and are
not intended to present financial position and results of operations in conformity with U.S. generally accepted accounting principles (GAAP):



| | - | Net profits income recorded for a month is the amount computed and paid by XTO Energy Inc., the owner of the
underlying properties, to Simmons Bank, as trustee (the Trustee) for the Trust. XTO Energy is a wholly owned subsidiary of Exxon Mobil Corporation. Net profits income consists of net proceeds received by XTO Energy from the underlying
properties in the prior month, multiplied by net profit percentages of 90% for the 90% net profits interests, and 75% for the 75% net profits interests.
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | - | Costs deducted in the calculation of net proceeds for the 90% net profits interests generally include
applicable taxes, transportation, marketing and legal costs. In addition to those costs, the 75% net profits interests include deductions for production expense, development costs, operating charges and other costs.
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | - | Net profits income is computed separately for each of five conveyances under which the net profits interests
were conveyed to the Trust. If monthly costs exceed revenues for any conveyance, such excess costs must be recovered, with accrued interest, from future net proceeds of that conveyance and cannot reduce net proceeds from the other conveyances.
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | - | Interest income and distribution payable to unitholders include interest earned on the previous months
investment.
| | - | -------------------------------------------------------------------------------------------------------------------



| | - | Trust expenses are recorded based on liabilities paid and cash reserves established by the Trustee for
liabilities and contingencies.
| | - | -------------------------------------------------------------------------------------------------------------------------------------



| | - | Distributions to unitholders are recorded when declared by the Trustee.
| | - | -----------------------------------------------------------------------

The Trusts financial statements differ from those prepared in conformity with U.S. GAAP because revenues are recognized
when received rather than accrued in the month of production, expenses are recognized when paid rather than when incurred, and certain cash reserves may be established by the Trustee for contingencies which would not be recorded under U.S. GAAP.
This comprehensive basis of accounting other than U.S. GAAP corresponds to the accounting permitted for royalty trusts by the U.S. Securities and Exchange Commission, as specified by Staff Accounting Bulletin Topic 12:E, Financial Statements of
Royalty Trusts.

Most accounting pronouncements apply to entities whose financial statements are prepared in accordance
with U.S. GAAP, directing such entities to accrue or defer revenues and expenses in a period other than when such revenues were received or expenses were paid. Because the Trusts financial statements are prepared on the modified cash basis, as
described above, most accounting pronouncements are not applicable to the Trusts financial statements.

##### Table of Contents

Impairment of Net Profits Interest

The Trustee reviews the Trusts net profits interests (NPI) in oil and gas properties for impairment whenever
events or circumstances indicate that the carrying value of the NPI may not be recoverable. In general, the Trustee does not view temporarily low prices as an indication of impairment. The markets for crude oil and natural gas have a history of
significant price volatility and though prices will occasionally drop significantly, industry prices over the long term will continue to be driven by market supply and demand. If events and circumstances indicate the carrying value may not be
recoverable, the Trustee would use the estimated undiscounted future net cash flows from the NPI to evaluate the recoverability of the Trust assets. If the undiscounted future net cash flows from the NPI are less than the NPI carrying value, the
Trust would recognize an impairment loss for the difference between the NPI carrying value and the estimated fair value of the NPI. The determination as to whether the NPI is impaired requires a significant amount of judgment by the Trustee and is
based on the best information available to the Trustee at the time of the evaluation. There was no impairment of the NPI during the quarter ended September 30, 2018.

Net profits interests in oil and gas properties

The initial carrying value of the net profits interests of $61,100,449 represents XTO Energys historical net book value
for the interests on February 12, 1991, the creation date of the Trust. Amortization of the net profits interests is calculated on a unit-of-production basis and is
charged directly to trust corpus. Accumulated amortization was $52,395,420 as of September 30, 2018 and $51,789,115 as of December 31, 2017.



|2. | Income Taxes
|-- | ------------

For federal income tax purposes, the Trust constitutes a fixed investment trust that is taxed as a grantor trust. A grantor
trust is not subject to tax at the trust level. Accordingly, no provision for income taxes has been made in the financial statements. The unitholders are considered to own the Trusts income and principal as though no trust were in existence.
The income of the Trust is deemed to have been received or accrued by each unitholder at the time such income is received or accrued by the Trust and not when distributed by the Trust. Impairments recorded for book purposes will not result in a loss
for tax purposes for the unitholders until the loss is recognized.

All revenues from the Trust are from sources within
Texas, Oklahoma or New Mexico. Because it distributes all of its net income to unitholders, the Trust has not been taxed at the trust level in New Mexico or Oklahoma. While the Trust has not owed tax, the Trustee is required to file an Oklahoma
income tax return reflecting the income and deductions of the Trust attributable to properties located in that state, along with a schedule that includes information regarding distributions to unitholders. Oklahoma and New Mexico tax the income of
nonresidents from real property located within those states, and the Trust has been advised by counsel that such states will tax nonresidents on income from the net profits interests located in those states. Oklahoma and New Mexico also impose a
corporate income tax that may apply to unitholders organized as corporations (subject to certain exceptions for S corporations and limited liability companies, depending on their treatment for federal tax purposes).

Texas imposes a franchise tax at a rate of 0.75% on gross revenues less certain deductions, as specifically set forth in the
Texas franchise tax statutes. Entities subject to tax generally include trusts and most other types of entities that provide limited liability protection, unless otherwise exempt. Trusts that receive at least 90% of their federal gross income from
certain passive sources, including royalties from mineral properties and other non-operated mineral interest income, and do not receive more than 10% of their income from operating an active trade or business,

##### Table of Contents

generally are exempt from the Texas franchise tax as passive entities. The Trust has been and expects to continue to be exempt from Texas franchise tax as a passive entity. Because
the Trust should be exempt from Texas franchise tax at the trust level as a passive entity, each unitholder that is a taxable entity under the Texas franchise tax will generally be required to include its Texas portion of trust revenues in its own
Texas franchise tax computation. This revenue is sourced to Texas under provisions of the Texas Administrative Code providing that such income is sourced according to the principal place of business of the Trust, which is Texas.

The Trust could potentially be required to bear a portion of the legal settlement costs arising from the Chieftainsettlement. For information on contingencies, see Note 3 to Condensed Financial Statements.In the event that the Trust is determined to be responsible for such costs, XTO will deduct the costs in its calculation of the net profits income
payable to the Trust from the applicable net profits interests. Thus, for unitholders, the legal settlement costs will be reflected through a reduction in net profits income received from the Trust and thus in a reduction in the gross royalty income
reported by and taxable to the unitholders. In the event that the Trustee objects to such claimed reductions, the Trustee may also incur legal fees in representing the Trusts interests. For unitholders, such costs would be reflected through an
increase in the Trusts administrative expenses, which would be deductible by unitholders in determining the net royalty income from the Trust.

Each unitholder should consult his or her own tax advisor regarding income tax requirements, if any, applicable to such
persons ownership of Trust units.

Unitholders should consult the Trusts latest annual report on Form 10-K for a more detailed discussion of federal and state tax matters.



|3. | Contingencies
|-- | -------------

In December 2010, a royalty class action lawsuit was filed against XTO Energy styled Chieftain Royalty Company v.
XTO Energy Inc.in Coal County District Court, Oklahoma. XTO Energy removed the caseto federal court in the Eastern District of Oklahoma. The plaintiffs alleged that XTO Energy wrongfully deducted fees from royalty payments on Oklahoma
wells, failed to make diligent efforts to secure the best terms available for the sale of gas and its constituents, and demanded an accounting to determine whether they have been fully and fairly paid gas royalty interests. The case was certified as
a class action in April 2012, then decertified in July 2013.

XTO Energy advised the Trustee that in December 2017, it
reached a tentative settlement with the plaintiffs for $80 million and an additional $750 thousand for costs to administer the settlement following final approval. On July 27, 2018, plaintiffs submitted their final plan of allocation
which was approved by the court on the same date. Based on the final plan of allocation XTO Energy has advised the Trustee that it believes approximately $40,000 in additional production costs should be allocated to the Trust. The Trustee has
objected to similar claims relating to the Chieftain settlement with respect to another trust for which it serves as trustee (the Hugoton Royalty Trust) pursuant to a demand for arbitration styled Simmons Bank (successor to Southwest Bank
and Bank of America, N.A.) vs. XTO Energy, Inc.through the American Arbitration Association seeking a declaratory judgment that theChieftainsettlement is not a production cost and that XTO Energy is prohibited from charging
thesettlement as a production cost under the conveyance or otherwise reducing the Hugoton Royalty Trusts payments now or in the future as a result of the Chieftain litigation. The Trustee has asked for additional information
regarding the allocation of the settlement amount to the Cross Timbers Royalty Trust and has asked to be advised by XTO Energy as the matter progresses. Once additional information is made available, the Trustee intends to review any claimed
reductions in

payment to the Trust based on the facts and circumstances of the settlement.

Other

Several states have enacted legislation requiring state income tax withholding from payments made to nonresident recipients of
oil and gas proceeds. After consultation with its tax counsel, the Trustee believes that it is not required to withhold on payments made to the unitholders. However, regulations are subject to change by the various states, which could change this
conclusion. Should amounts be withheld on payments made to the Trust or the unitholders, distributions to the unitholders would be reduced by the required amount, subject to the filing of a claim for refund by the Trust or unitholders for such
amount.



|4. | Excess Costs
|-- | ------------

If monthly costs exceed revenues for any conveyance, such excess costs must be recovered, with accrued interest, from future
net proceeds of that conveyance and cannot reduce net proceeds from other conveyances.

The following summarizes excess
costs activity, cumulative excess costs balances and accrued interest to be recovered by conveyance:

5. XTO Energy Inc.

In computing net proceeds for the 75% net profits interests, XTO Energy deducts an overhead charge as reimbursement for costs
associated with monitoring these interests. This monthly overhead charge at September 30, 2018 was $39,834 ($29,876 NPI) and is subject to annual adjustment based on an oil and gas industry index.

XTO Energy deducts a monthly overhead charge for reimbursement of administrative expenses as operator of the Hewitt Unit,
which is one of the properties underlying the Oklahoma 75% net profits interests. As of September 30, 2018, this monthly charge was approximately $28,000 ($21,000 NPI) and is subject to annual adjustment based on an oil and gas industry index.

Distributable
Income

Quarter

For the quarter ended September 30, 2018, net profits income was $2,257,576 compared to $1,674,186 for third quarter 2017. This 35%
increase in net profits income is primarily the result of higher oil prices ($0.8 million), increased oil production ($0.1 million), decreased development costs ($0.1 million) and decreased production expenses ($0.1 million), partially offset by net
excess costs activity on the Texas working interest properties ($0.2 million), and decreased gas production ($0.3 million). See Net Profits Income below.

After considering interest income of $5,744 and administration expense of $118,614, distributable income for the quarter ended
September 30, 2018 was $ 2,144,706, or $0.357451 per unit of beneficial interest. Administration expense for the quarter decreased $31,431 from the prior year quarter, primarily related to the timing of receipt and payment of Trust expenses and
terms of professional services. Changes in interest income are attributable to fluctuations in net profits income and interest rates. For third quarter 2017, distributable income was $1,526,430, or $0.254405 per unit.

Nine Months

For the nine months ended September 30, 2018, net profits income was $6,868,248 compared to $4,931,974 for the same 2017 period. This 39%
increase in net profits income is primarily the result of increased oil and gas prices ($1.9 million), decreased development costs ($0.3 million) and increased oil production ($0.2 million), partially offset by decreased gas production ($0.3
million), increased taxes, transportation and other ($0.1 million) and net excess costs activity on the Texas working interest properties ($0.1 million). See Net Profits Income below.

After considering interest income of $13,919 and administration expense of $537,953, distributable income for the nine months ended
September 30, 2018 was $6,344,214, or $1.057369 per unit of beneficial interest. Administration expense for the nine months ended September 30, 2018 increased $32,573 from the prior year nine-month period, primarily related to the timing
of receipt and payment of Trust expenses and terms of professional services. Changes in interest income are attributable to fluctuations in net profits income and interest rates. For the nine months ended September 30, 2017, distributable
income was $4,431,402, or $0.738567 per unit.

Net Profits Income

Net profits income is recorded when received by the Trust, which is the month following receipt by XTO Energy and generally two months after
oil production and three months after gas production. Net profits income is generally affected by three major factors:



| | - | oil and gas sales volumes,
| | - | --------------------------



| | - | oil and gas sales prices, and
| | - | -----------------------------



| | - | costs deducted in the calculation of net profits income.
| | - | --------------------------------------------------------

Because properties underlying the 90% net profits interests are primarily royalty and overriding royalty interests, the calculation of net
profits income from these interests includes deductions for production and property taxes, legal costs, and marketing and transportation charges. In addition to these costs, the calculation of net profits income from the 75% net profits interests
includes deductions for production expense, development costs and overhead since the related underlying properties are working interests.

|(a) | Because of the interval between time of production and receipt of royalty income by the Trust,
(1) oil and gas sales for the quarter ended September 30 generally represent oil production for the period May through July and gas production for the period April through June and (2) oil and gas sales for the nine-months ended
September 30 generally represent oil production for the period November through July and gas production for the period October through June.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(b) | Oil and gas sales volumes are allocated to the net profits interests by dividing Trust net cash
inflows by average sales prices. As oil and gas prices change, the Trusts allocated production volumes are impacted as the quantity of production necessary to cover expenses changes inversely with price. As such, the underlying property
production volume changes may not correlate with the Trusts allocated production volumes in any given period. Therefore, comparative discussion of oil and gas sales volumes is based on the underlying properties.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(c) | Production expense includes an overhead charge which is deducted and retained by the operator. XTO
Energy deducts an overhead charge as reimbursement for costs associated with monitoring these interests. See Note 5 to Condensed Financial Statements.

##### Table of Contents

The following are explanations of significant variances on the underlying properties from third
quarter 2017 to third quarter 2018 and from the first nine months of 2017 to the comparable period in 2018:

Sales Volumes

Oil

Oil sales volumes
increased 4% for the third quarter and increased 2% for the first nine months of 2018 primarily because of the timing of cash receipts partially offset by natural production decline.

Gas

Gas sales volumes
decreased 18% for third quarter 2018 primarily because of the timing of cash receipts and natural production decline. Gas sales volumes decreased 5% for the nine-month period primarily because of natural production decline, partially offset by the
timing of cash receipts.

The estimated rate of natural production decline on the underlying oil and gas properties is approximately 6% to
8% a year.

Sales Prices

Oil

The average oil
price increased 43% to $62.65 per Bbl for the third quarter and increased 29% to $58.62 per Bbl for the nine-month period. The third quarter 2018 oil price is primarily related to production from May through July 2018, when the average NYMEX price
was $69.36 per Bbl.

Gas

Gas prices for the third quarter were relatively flat at $4.15 per Mcf and for the nine-month period increased 6% to $4.39 per Mcf. The third
quarter 2018 gas price is primarily related to production from April through June 2018, when the average NYMEX price was $2.80 per MMBtu.

Costs

Taxes,
Transportation and Other

Taxes, transportation and other costs decreased 3% for the third quarter primarily because of lower other
deductions and production taxes related to decreased gas revenues, partially offset by higher production taxes related to increased oil revenues. Taxes, transportation and other costs increased 7% for the nine-month period primarily because of
higher oil production taxes related to increased oil revenues.

Production Expense

Production expense decreased 10% for the third quarter primarily because of decreased overhead and power and fuel costs. Production expense
decreased 1% for the nine-month period primarily because of decreased overhead, labor and repairs and maintenance costs, partially offset by secondary recovery costs.

Development Costs

Development costs decreased 42% for the third quarter and 33% for the nine-month period primarily because of decreased activity and costs,
related to the timing or selection of projects by unit operators on the Texas and Oklahoma oil properties underlying the 75% net profits interests.

Excess Costs

If monthly
costs exceed revenues for any conveyance, such excess costs must be recovered, with accrued interest, from future net proceeds of that conveyance and cannot reduce net proceeds from any other conveyance. Underlying cumulative excess costs for the
Texas working interest conveyance remaining as of September 30, 2018 totaled $1.8 million, including accrued interest of $0.2 million. For further information on excess costs, see Note 4 to Condensed Financial Statements.

Contingencies

For
information on contingencies, see Note 3 to Condensed Financial Statements.

Forward-Looking Statements

Statements in this report relating to future plans, predictions, events or regulatory decisions are forward-looking statements. All statements
other than statements of historical fact included in this Form 10-Q including, without limitation, statements regarding the net profits interests, underlying properties, development activities, annual or
monthly development, production and other costs and expenses, oil and gas prices and differentials to NYMEX prices, distributions to unitholders, and industry and market conditions, are forward-looking statements that are subject to risks and
uncertainties, including those detailed in Part I, Item 1A of the Trusts Annual Report on Form 10-K for the year ended December 31, 2017, which is incorporated by this reference as though fully set
forth herein. XTO Energy and the Trustee assume no duty to update these statements as of any future date.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

Not applicable. Upon qualifying as a smaller reporting company, this information is no longer required.

Item 4. Controls and Procedures.

As of the end of the period covered by this report, the Trustee carried out an evaluation of the effectiveness of the Trusts disclosure
controls and procedures pursuant to Exchange Act Rules 13a-15 and 15d-15. Based upon that evaluation, the Trustee concluded that the Trusts disclosure controls and
procedures are effective in recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by the Trust in the reports that it files or submits under the Securities Exchange Act of 1934 and are effective in
ensuring that information required to be disclosed by the Trust in the reports that it files or submits under the Securities Exchange Act of 1934 is accumulated and communicated to the Trustee to allow timely decisions regarding required disclosure.
In its evaluation of disclosure controls and procedures, the Trustee has relied, to the extent considered reasonable, on information provided by XTO Energy. There has not been any change in the Trusts internal control over financial reporting
during the period covered by this report that has materially affected, or is reasonably likely to materially affect, the Trusts internal control over financial reporting.
